[Complications of urinary incontinence surgery: 800 procedures].

OBJECTIVE: To present the complications of urinary incontinence surgery through our experience over 13 years with 800 procedures in continuous practice. These complications were compared to those of the literature for the same type of procedure. STUDY DESIGN: From January 1988 to September 2001, 800 procedures were performed in the same hospital in the gynecology unit. The procedures were: Bologna (91 cases), laparotomic Burch (83 cases), laparoscopic Burch (62 cases), Pereyra (112 cases), Stamey (8 cases), Ingelman-Sundberg (27 cases), Mouchel (40 cases), autograft sling (22 cases), mesh sling: small size (62 cases), large size (12 cases) et TVT (tension free vaginal tape) (281 cases). These procedures were performed alone in 475 cases (125 cases with hysterectomy for other reason), and in 325 cases associated with prolapse surgery. The complications were noted during the hospitalization and at the control at 3 months and 1 year. We only noted the complications attributable to the different procedures. RESULTS: Bladder injuries are found in 3.5% (0 to 6%), hemorrhage in 1% (0 to 3.8%), urinary infection in 4.5% (0 to 11.3%), fever at 48 hours in 1.5% (0 to 9.7%), momentary urine retention in 17% (1.6 to 64.5%), de novo dysuria in 10.9% (0 to 35.5%), de novo urge in 6.9% (0 to 11%). For the other complications, which were less frequent or more procedure-specific, we noted: subcutaneous emphysema in 1.6% of the laparoscopic Burch procedures, cutting thread in 4.8% of the laparoscopic Burch procedures and 2.7% in Pereyra, rejection of prosthetic mesh in 9% of the large slings, 14% with the small sling and 28.2% with the Mouchel procedure, a wound abscess in 3.8% of the Bologna procedures, 1.2% of laparotomic Burch procedures. The percentage of women who had at least one complication was a minimum of 18% for TVT and a maximum of 62.9% for small synthetic sling. In summary, 32% of the patients presented at least one complication. Overall, we noted urinary complications in 41% of the patients, which accounted for 81% of the complications. DISCUSSION: We reviewed more than 100 references concerning complications of the procedures performed in these patients. "Blind" procedures gave more bladder injuries, slings more dysuria and urine retention and procedures using mesh gave more pool healing or rejection especially with the old materials. A particular place must be made for the TVT, recent procedure, which is widely studied. We reviewed 35 references explaining complications of TVT or proposing preventions measures. CONCLUSION: There are many complications of urinary incontinence surgery, but the majority is quickly resolved without consequence. The only after-effects are dysuria which are the most often slow micturition, and urge which are a real problem, sometimes leading to sling removal.

A quality rating scale for aesthetic surgical procedures.

BACKGROUND: Cosmetic dermatologic procedures offer the promise of visible aesthetic enhancement with minimal risk. While in recent years the number of available procedures has proliferated, there are few objective methods for evaluating the relative quality of these procedures for particular indications or specific patients. OBJECTIVE: (A) To develop a simple, easy-to-use numerical rating scale to assess the quality of cosmetic surgical procedures on a range of parameters pertaining to clinical efficacy and patient satisfaction; (B) to statistically validate the discriminative value of this rating scale. METHODS: (A) Patient and physician interviews were performed to elicit a list of factors that may collectively characterize the clinical efficacy and patient tolerability of cosmetic dermatologic procedures. A 0-100 point rating scale was developed based on these factors, with the face-validity of this scale checked by a group of patients and physicians; (B) Statistical analysis of the questionnaire was performed by asking 15 expert cosmetic dermatologic surgeons to use it to rate 23 common cosmetic dermatologic procedures, and analyzing the results. RESULTS: (A) An easy-to-use scale was constructed to assess the quality of cosmetic dermatologic procedures by rating the associated cost, risk, time (procedure and recovery), discomfort, results, and longevity of benefit. A "physician adjustment factor" was used to further increase the relevance of this 0-100 point scale for specific patients; (B) Repeated-measures analysis of variations (ANOVAs) performed on the data from the survey of experts demonstrated that this scale can be used to discriminate between common dermatologic procedures. The differences in mean subscores and total scores among procedures grouped by anatomic site and target lesion-type were significant at the level of P < .05. LIMITATIONS: Patient preferences exogenous to the rating scale may increase or decrease the suitability of specific procedures. CONCLUSIONS: Common cosmetic dermatologic procedures are of uniformly high quality, as per expert ratings on a systematic measure. This quality rating scale appears statistically valid and robust, given that expert raters assigned similar ratings to the same procedures but mean ratings were different across procedures. In the future, this quality rating scale can be used to assess novel interventions, and to help dermatologic surgeons faced with patient concern to optimally select among alternative procedures for a given indication.

Effect of the Cox maze procedure on the secretion of atrial natriuretic peptide.

OBJECTIVES: The Cox maze procedure has been confirmed to be effective in curing atrial fibrillation. Some authors have reported severe fluid retention after the Cox maze procedure and have suggested decreased secretion of atrial natriuretic peptide as a possible mechanism. This study was designed (1) to examine the serial changes in atrial natriuretic peptide after the Cox maze procedure as compared with changes occurring after coronary artery bypass grafting and (2) to elucidate any differences in atrial natriuretic peptide levels between patients with transient recurrence of atrial fibrillation after the Cox maze procedure and those without recurrence of atrial fibrillation. METHODS: Blood samples were drawn from the right and left atria in patients undergoing the Cox maze procedure (n = 19) and from the right atrium in patients undergoing coronary artery bypass grafting (n = 6) before and 1, 2, and 3 days after the operation. In six patients undergoing the Cox maze procedure, samples were also drawn from the radial artery before and 1, 2, 3, 5, and 7 days after the operation. The plasma samples were prepared by refrigerated centrifugation and stored until radioimmunoassay. In the Cox maze procedure group, atrial natriuretic peptide levels in the right atrium were 629 +/- 366, 154 +/- 112, 162 +/- 112, and 183 +/- 97 pg/ml and those in the left atrium were 276 +/- 168, 152 +/- 91, 162 +/- 111, and 145 +/- 80 pg/ml before and 1, 2, and 3 days after the operation, respectively. A marked decrease in atrial natriuretic peptide levels was evident after the Cox maze procedure (p < 0.001). There was no significant correlation between atrial natriuretic peptide levels and atrial pressures after the Cox maze procedure, which suggests that secretion of atrial natriuretic peptide by the atria was impaired. There was a significant correlation between the atrial natriuretic peptide levels in the left atrium and those in the peripheral radial artery, and the decreased levels of atrial natriuretic peptide in the radial artery continued for 7 days after the Cox maze procedure. There were no differences in the atrial natriuretic peptide levels between the patients with transient recurrence of atrial fibrillation (n = 6) and those without recurrence (n = 13) after the Cox maze procedure. In the coronary artery bypass grafting group, the atrial natriuretic peptide levels in the right atrium were 115 +/- 37, 124 +/- 48, 154 +/- 54, and 156 +/- 36 pg/ml before and 1, 2, and 3 days after the operation, respectively. No change was seen after the operation. CONCLUSIONS: We observed a significant decrease in atrial natriuretic peptide levels after the Cox maze procedure. This may be one of the possible causes of fluid retention after this procedure. These decreased atrial natriuretic peptide levels after the Cox maze procedure may result from the multiple atriotomy incisions and excision of both atrial auricles performed during the procedure, rather than from the conversion of atrial fibrillation to normal sinus rhythm.

Physician discretion and racial variation in the use of surgical procedures.

BACKGROUND: Racial variation in the use of surgical procedures raises concern about equitable access. The goal of our study was to examine racial differences in utilization across a broad range of procedures in Massachusetts and to assess whether racial variation is related to physician discretion. METHODS: We obtained fiscal year 1988 hospital discharge data for all Massachusetts residents, identified 10 clinically important surgical procedures, and calculated age- and sex-adjusted rate ratios for white and black patients. Level of discretion was determined by using a modified Delphi technique. RESULTS: Whites had higher rates for eight procedures (abdominal aortic aneurysm repair, appendectomy, cardiac valve replacement, carotid endarterectomy, cholecystectomy, lumbar disk procedures, open reduction/internal fixation of the femur, and tonsillectomy) and lower rates for two procedures, hysterectomy and prostatectomy. Of the eight procedures for which utilization was higher among whites, four were ranked as moderate- or high-discretion procedures and four were ranked as low-discretion procedures. Hysterectomy, the only procedure for which utilization was substantially higher among blacks (white:black rate ratio < 0.90), was ranked as a high-discretion procedure. CONCLUSIONS: With the exception of hysterectomy and prostatectomy, procedure rates for whites were greater than those for blacks for a wide range of surgical procedures. Racial variation exists for low-discretion procedures as well as for those associated with moderate and high discretion. Variation among low-discretion procedures that is not explained by medical need suggests the possibility of race-related differences in access to care or in the way patients and physicians make clinical decisions.

Comparison of 1997 Medicare relative value units for gender-specific procedures: is Adam still worth more than Eve?

BACKGROUND: On January 1, 1992, Congress implemented a Medicare payment system based on relative value units (RVUs). The total RVU (which is made up of work, practice, and malpractice RVUs) is multiplied by a dollar conversion factor to set the reimbursement for all procedures covered by Medicare. In a previous study, we found that significant gender bias exists in Medicare reimbursement for female-specific services. Recently, HCFA approved increases (beginning January 1997) in the work RVU for many gynecologic procedures. This study was undertaken to compare work and total RVUs for gender-specific procedures effective January 1, 1997. METHODS: Using the May 1996 Federal Register, we compared work and total RVUs for 24 pairs of gender-specific procedures. The groups were matched so that the amount of work and level of difficulty would be similar, if not identical. We validated our selection of procedures for comparison by also evaluating the average time required to perform these procedures. RESULTS: Comparison of work RVUs for the 24 paired procedures revealed that in 19 cases (80%), male-specific procedures had a higher RVU; in 3 cases (12%), female-specific procedures were higher; and in 2 cases, there was no difference. On average, work RVUs were 49% higher for urologic procedures than for gynecologic procedures. Comparison of total RVUs revealed that in 20 cases (83%), urologic procedures had a higher total RVU and in 3 cases (12%), gynecologic procedures were higher. On average, male-specific surgeries are reimbursed at an amount which is 37% higher than that for female-specific surgeries. CONCLUSION: Recent increases in work RVUs for many gynecologic procedures have resulted in improved reimbursement. However, even with these improvements, significant gender bias still exists in the Medicare reimbursement of female-specific procedures. This gender bias is further magnified as more private insurance carriers use the system to set reimbursement.

Pain behaviors observed during six common procedures: results from Thunder Project II.

OBJECTIVE: Patients frequently display behaviors during procedures that may be pain related. Clinicians often rely on the patient's demonstration of behaviors as a cue to presence of pain. The purpose of this study was to identify specific pain-related behaviors and factors that predict the degree of behavioral responses during the following procedures: turning, central venous catheter insertion, wound drain removal, wound care, tracheal suctioning, and femoral sheath removal. DESIGN: Prospective, descriptive study. SETTING: Multiple units in 169 hospitals in United States, Canada, England, and Australia. PATIENTS: A total of 5,957 adult patients who underwent one of the six procedures. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A 30-item behavior observation tool was used to note patients' behaviors before and during a procedure. By comparing behaviors exhibited before and during the procedure as well as behaviors in those with and without procedural pain (as noted on a 0-10 numeric rating scale), we identified specific procedural pain behaviors: grimacing, rigidity, wincing, shutting of eyes, verbalization, moaning, and clenching of fists. On average, there were significantly more behaviors exhibited by patients with vs. without procedural pain (3.5 vs. 1.8 behaviors; t = 38.3, df = 5072.5; 95% confidence interval, 1.6-1.8). Patients with procedural pain were at least three times more likely to have increased behavioral responses than patients without procedural pain. A simultaneous regression model determined that 33% of the variance in amount of pain behaviors exhibited during a procedure was explained by three factors: degree of procedural pain intensity, degree of procedural distress, and undergoing the turning procedure. CONCLUSIONS: Because of the strong relationship between procedural pain and behavioral responses, clinicians can use behavioral responses of verbal and nonverbal patients to plan for, implement, and evaluate analgesic interventions.

Multiple combined indirect procedure for the surgical treatment of children with moyamoya disease. A comparison with single indirect anastomosis and direct anastomosis.

Considering three different bypass procedures now in use, (single indirect nonanastomotic bypass procedure, multiple combined indirect (MCI) nonanastomotic procedure and direct anastomosis), the authors attempted to identify the most appropriate bypass procedure for treating ischemic-type moyamoya disease in children. The authors performed three procedures (the original encephaloduroarteriosynangiosis [EDAS] alone, the frontotemporoparietal combined indirect bypass procedure, and the superficial temporal artery--middle cerebral artery [STA-MCA] anastomosis with encephalomyosynangiosis [EMS]) on 72 hemispheres in 50 patients with pediatric moyamoya disease. Analyses were then performed to compare postoperative collateral vessel formation found on angiograms, complications, and clinical improvements. Postoperative collateral formations were observed in more than two-thirds of the MCA distribution after the EDAS alone, the MCI procedure, and the direct anastomosis in 44%, 52%, and 74% of the surgically treated hemispheres, respectively. In addition, frontal encephalomyoarteriosynangiosis of the MCI bypass procedure formed collateral vessels of the anterior cerebral artery distribution in 94% of the treated hemispheres. Postoperatively, clinical symptoms resolved in 56%, 63%, and 74% of the treated sides 1 year after EDAS alone, MCI procedure, and the direct anastomosis, respectively. One patient suffered a minor stroke after EDAS alone, two patients developed epidural hematomas after the MCI procedure, and one patient suffered a major stroke and one patient a minor stroke after undergoing direct anastomosis. The direct anastomosis procedure was found to result in the best postoperative collateral vessel formation and clinical improvement. However, the single and multiple combined indirect nonanastomotic bypass procedures were found to be safer than direct anastomosis. Furthermore, the frontotemporoparietal combined indirect bypass procedure caused the formation of collateral circulation not only in the MCA but also in the ACA distribution. Based on analysis of these findings, the authors recommend the MCI procedure as the appropriate surgical procedure in the treatment of children with moyamoya disease, although the best treatment is the STA-MCA anastomosis with EMS when feasible.

Enhancing procedural training in a family practice residency.

BACKGROUND AND OBJECTIVES: Teaching outpatient procedures is a major responsibility of family practice residencies. This requires equipment, faculty expertise, and curricula. This report documents one residency program's attempt to enhance the teaching of outpatient procedures. METHODS: We tabulated all office procedures completed during the years 1993 through 1996 at a family practice residency program in the southeastern United States. We compared the number of procedures and dollar charges before and during an educational intervention designed to increase the number of procedures performed and to improve procedural training of residents. The intervention consisted of hiring a full-time procedural nurse and new procedural equipment. RESULTS: The residency program spent $177,000 over 4 years to improve procedural training, but income from procedures was estimated to be only $127,000. From 1993 to 1996, the total number of annual procedures increased from 322 to 540. Both the number of procedures and procedural income declined in the final year of the project when the procedural nurse assumed other clinical and administrative duties. CONCLUSIONS: Volume and teaching of common procedures in a family practice residency program can be enhanced by a dedicated effort, but this effort requires considerable staffing and financial resources.

Combined procedures in laparoscopic surgery.

With advancements in minimal access surgery, combined laparoscopic procedures are now being performed for treating coexisting abdominal pathologies at the same surgery. In our center, we performed 145 combined surgical procedures from January 1999 to December 2002. Of the 145 procedures, 130 were combined laparoscopic/endoscopic procedures and 15 were open procedures combined with endoscopic procedures. The combination included laparoscopic cholecystectomy, various hernia repairs, and gynecological procedures like hysterectomy, salpingectomy, ovarian cystectomy, tubal ligation, urological procedures, fundoplication, splenectomy, hemicolectomy, and cystogastrostomy. In the same period, 40 patients who had undergone laparoscopic cholecystectomy and 40 patients who had undergone ventral hernia repair were randomly selected for comparison of intraoperative outcomes with a combined procedure group. All the combined surgical procedures were performed successfully. The most common procedure was laparoscopic cholecystectomy with another endoscopic procedure in 129 patients. The mean operative time was 100 minutes (range 30-280 minutes). The longest time was taken for the patient who had undergone laparoscopic splenectomy with renal transplant (280 minutes). The mean hospital stay was 3.2 days (range 1-21 days). The pain experienced in the postoperative period measured on the visual analogue scale ranged from 2 to 5 with a mean of 3.1. Of 145 patients who underwent combined surgical procedures, 5 patients developed fever in the immediate postoperative period, 7 patients had port site hematoma, 5 patients developed wound sepsis, and 10 patients had urinary retention. As long as the basic surgical principles and indications for combined procedures are adhered to, more patients with concomitant pathologies can enjoy the benefit of minimal access surgery. Minimal access surgery is feasible and appears to have several advantages in simultaneous management of two different coexisting pathologies without significant addition in postoperative morbidity and hospital stay.

A new era in the surgical treatment of atrial fibrillation: the impact of ablation technology and lesion set on procedural efficacy.

BACKGROUND/OBJECTIVE: While the Cox-Maze procedure remains the gold standard for the surgical treatment of atrial fibrillation (AF), the use of ablation technology has revolutionized the field. To simplify the procedure, our group has replaced most of the incisions with bipolar radiofrequency ablation lines. The purpose of this study was to examine results using bipolar radiofrequency in 130 patients undergoing a full Cox-Maze procedure, a limited Cox-Maze procedure, or pulmonary vein isolation alone. METHODS: A retrospective review was performed of patients who underwent a Cox-Maze procedure (n = 100), utilizing bipolar radiofrequency ablation, a limited Cox-Maze procedure (n = 7), or pulmonary vein isolation alone (n = 23). Follow-up was available on 129 of 130 patients (99%). RESULTS: Pulmonary vein isolation was confirmed by intraoperative pacing in all patients. Cross-clamp time in the lone Cox-Maze procedure patients was 44 +/- 21 minutes, and 104 +/- 42 minutes for the Cox-Maze procedure with a concomitant procedure, which was shortened considerably from our traditional cut-and-sew Cox-Maze procedure times (P < 0.05). There were 4 postoperative deaths in the Cox-Maze procedure group and 1 in the pulmonary vein isolation group. The mean follow-up was 13 +/- 10, 23 +/- 15, and 9 +/- 10 months for the Cox-Maze IV, the pulmonary vein isolation, and the limited Cox-Maze procedure groups, respectively. At last follow-up, freedom from AF was 90% (85 of 94), 86% (6 of 7), and 59% (10 of 17) in the in the Cox-Maze procedure group, limited Cox-Maze procedure group, and pulmonary vein isolation alone group, respectively. CONCLUSIONS: The use of bipolar radiofrequency ablation to replace Cox-Maze incisions was safe and effective at controlling AF. Pulmonary vein isolation alone was much less effective, and should be used cautiously in this population.

The closure of iatrogenic membrane defects after amniocentesis and endoscopic intrauterine procedures.

OBJECTIVE: To describe a new technique for wound closure after endoscopic intrauterine procedures which prevents amniotic fluid leakage after the procedure. STUDY DESIGN: This is an observational study which reviews a new technique under an IRB-approved protocol. The rationale for this study was the increasing frequency of intrauterine endoscopic procedures. The most common complication of these procedures is persistent leakage of amniotic fluid from puncture sites, which can result in preterm labor and preterm delivery. Thus, these procedures carry a high morbidity rate that may overcome the benefit of the intervention. We have employed a new technique, which has successfully prevented amniotic fluid leakage following the procedure. The instruments used for the endoscopic procedures were no larger than 3.5 mm for all cases. A sealant of platelets was rapidly injected followed by injection of fibrin glue and powdered collagen slurry at each puncture site. Sonography for modified AFI, clinical examination for nitrazine and ferning, and pad count were performed after each procedure at three intervals: immediately after the procedure, 24 h and 48 h. RESULTS: Eight patients undergoing an endoscopic intrauterine procedure (either cord ligation for twin-twin transfusion syndrome or sealing of ruptured membranes after amniocentesis) were included. All patients were treated between 18 and 24 weeks of gestation. Sonography, clinical examination and pad count revealed no evidence of amniotic fluid leakage either intra-abdominally or vaginally in any of the patients. There was 1 patient who ruptured membranes 12 h after the procedure due to severe vomiting. Another patient elected to terminate the pregnancy 48 h after the procedure without evidence of leakage. The remaining patients continued for 8 weeks or more without fluid leakage. CONCLUSION: The technique described, immediate sealing of puncture wounds following endoscopic intrauterine procedures, is effective in preventing amniotic fluid loss after the procedure.

Variation in training for interventional pulmonary procedures among US pulmonary/critical care fellowships: a survey of fellowship directors.

STUDY OBJECTIVES: The American College of Chest Physicians has published guidelines recommending minimum competency requirements for 17 interventional pulmonary procedures. Our aim was to assess what procedures are offered to fellows in US pulmonary/critical care fellowships and to determine whether the recommended competency numbers are being met. METHODS: Surveys were mailed to 122 pulmonary/critical care fellowship directors in the United States, and fellowship demographics, the types of procedures offered, and the average number of procedures performed were recorded. The presence of a dedicated interventional pulmonologist (IP) was ascertained, and procedural offerings and volume were compared with programs that did not have an IP. RESULTS: The response rate of the survey was 77%. There was wide variation in the procedures offered by different programs. The presence of an IP was associated with an increased likelihood of advanced procedural training in brachytherapy (p < 0.05), electrocautery/argon plasma coagulation (p < 0.001), stents (p < 0.001), laser therapy (p < 0.01), rigid bronchoscopy (p < 0.001), and cryotherapy (p < 0.05). For only 3 of the 17 procedures did > 50% of the programs reach the targeted numbers to obtain competency. CONCLUSIONS: There is a large variation in the spectrum of pulmonary procedures offered to trainees. Programs with a dedicated IP are more likely to offer training in advanced therapeutic procedures. When interventional procedures are offered by fellowships, < 30% of programs meet the competency recommendations. These findings have implications for training, delivery of care, and research. An extra year of fellowship in interventional pulmonology might be desirable if one is to reach the desired competency numbers. An alternative to reaching the recommended numbers for select procedures would be to consider regionalizing care at centers that perform many procedures. Finally, to provide justification for the current competency recommendations, clinical outcomes should be correlated with physicians' procedural volume, as has been done in other subspecialties.

Post-surgical infections: prevalence associated with various periodontal surgical procedures.

BACKGROUND: Of the various adverse outcomes that may be encountered following periodontal surgery, the risk of infection stands at the forefront of concern to the surgeon, since infection can lead to morbidity and poor healing outcomes. This paper describes a large-scale retrospective study of multiple surgical modalities in a diverse periodontal practice undertaken to explore the prevalence of clinical infections post-surgically and the relationship between diverse treatment variables and infection rates. METHODS: A retrospective review of all available periodontal surgical records of patients treated in the Department of Periodontics at Wilford Hall Medical Center, San Antonio, Texas, was conducted. The sample comprised 395 patients and included 1,053 fully documented surgical procedures. Surgical techniques reviewed included osseous resective surgery, flap curettage, distal wedge procedures, gingivectomy, root resection, guided tissue regeneration, dental implant surgery, epithelialized free soft tissue autografts, subepithelial connective tissue autografts, coronally positioned flaps, sinus augmentations, and ridge preservation or augmentation procedures. Infection was defined as increasing and progressive swelling with the presence of suppuration. The impact of various treatment variables was examined including the use of bone grafts, membranes, soft tissue grafts, post-surgical chlorhexidine rinses, systemic antibiotics, and dressings. Results were analyzed using Fisher's exact test and Pearson's chi-square test. RESULTS: Of the 1,053 surgical procedures evaluated in this study, there were a total of 22 infections for an overall prevalence of 2.09%. Patients who received antibiotics as part of the surgical protocol (pre- and/ or post-surgically) developed eight infections in 281 procedures (2.85%) compared to 14 infections in 772 procedures (1.81%) where antibiotics were not used. Procedures in which chlorhexidine was used during post-surgical care had a lower infection rate (17 infections in 900 procedures, 1.89%) compared to procedures after which chlorhexidine was not used as part of post-surgical care (five infections in 153 procedures, 3.27%). The use of a post-surgical dressing demonstrated a slightly higher rate of infection (eight infections in 300 procedures, 2.67%) than non-use of a dressing (14 infections in 753 procedures, 1.86%). Despite these trends, no statistically significant relationship was found between post-surgical infection and any of the treatment variables examined, including the use of perioperative antibiotics. CONCLUSIONS: The results of this study confirm previous research demonstrating a low rate of postoperative infection following periodontal surgical procedures. Although perioperative antibiotics are commonly used when performing certain regenerative and implant surgical procedures, data from this and other studies suggest that there may be no benefit in using antibiotics for the sole purpose of preventing post-surgical infections. Further large-scale, controlled clinical studies are warranted to determine the role of perioperative antibiotics in the prevention of periodontal post-surgical infections.

[Appropriateness of medical procedures: measurements and relations with needs and access to health care].

Efforts to reduce cost expenditures and improve quality of care have raised some concern over the recent years as to the appropriateness of medical procedures. However, the relationships between the appropriateness of medical procedures, the need for such procedures and access to health care have not been described in detail. The appropriateness of medical procedures is usually measured on the basis of procedures actually performed. We present a critical appraisal of this type of measurement. From a population point of view, measurement of appropriateness does not actually reflect simply those procedures which have been performed, but rather involves three parameters: needs for a particular procedure, access to the procedure by those who need it, and non performance of the procedure among those who do not need it. This analysis revealed three consequences. First, there is an inverse relationship between access to a procedure among subjects who need the procedure and the appropriateness of such a procedure among those who do not need it. Secondly, comparisons of appropriateness rates between individual facilities or between regions must take into account the need for this procedure in the general population. Finally, it is possible to observe similar rates of procedure performance between regions or social groups despite major regional or social differences in appropriateness and access to health care.

Selling comfort: A survey of interventions for needle procedures in a pediatric hospital.

Abstract Needle procedures are a necessary component of the treatment of hospitalized children. However, for many children they can be both painful and distressing. There was concern among the nurses at our pediatric hospital that we were not adequately controlling pain from needle procedures. We were interested in obtaining more information about the incidence and types of needle procedures and the current use of topical analgesics. A survey was designed to describe the frequency, type, time to complete, and perceived ease of needle procedures. The use of topical anesthetics and other comfort measures was also examined. The most common needle procedures performed were venipunctures for blood work, followed by intravenous cannulations, capillary sticks, port-a-cath access, and intramuscular injections. In total, 387 procedures were performed over a 23-day period. The majority of the procedures were perceived as easy, and the modal time to complete the procedures was 5 minutes. A topical anesthetic was used for 74 procedures (i.e., 19%), and the majority of these procedures were performed on the medical day unit with oncology patients. Results of the survey provided information about the day-to-day practice of needle procedures in order to identify both the supports and the barriers to providing these procedures atraumatically. Examining needle procedures within a framework of atraumatic care broadened our perspective and enabled us to integrate the use of topical anesthetics as just one of a number of strategies to minimize the pain and distress associated with needle procedures.

Comparison of three dosing procedures for administration of bovine surfactant to neonates with respiratory distress syndrome.

A multicenter, randomized, double-blind, controlled trial compared three beractant (Survanta) administration procedures in the treatment of neonatal respiratory distress syndrome. Infants weighing > or = 600 gm with respiratory distress syndrome who required assisted ventilation were treated within 8 hours of birth with beractant administered intratracheally. Procedure A required administration in two fractional doses after removal of the infant from the ventilator. Procedure B required administration in two fractional doses through a neonatal suction valve and did not require removal of the infant from the ventilator, and procedure C required administration in four fractional doses during removal from the ventilator. Procedure C is the method used in all previous beractant studies. Of the 299 infants enrolled, 103 were randomly assigned to procedure A, 100 to procedure B, and 96 to procedure C. The results indicate no significant differences among the treatment groups in the clinical outcome measures of fractional inspired oxygen, mean airway pressure, and arterial-alveolar ratio of partial pressure of oxygen at 72 hours of life, or in the incidences of air leaks, pulmonary interstitial emphysema, or death through 72 hours of life. There were no significant differences in the lowest heart rates recorded during administration of doses, but there was less oxygen desaturation during administration of dose 1 with procedure B than with procedure A (p = 0.001), and more reflux of beractant after procedure B than after procedure C (p = 0.007). We conclude that the three procedures are equally effective and can be used to administer beractant safely and effectively. Procedure B has the advantage of allowing administration without interrupting mechanical ventilation.

Local anaesthetic endonasal endoscopic laser dacryocystorhinostomy: analysis of patients' acceptability and various factors affecting the success of this procedure.

BACKGROUND AND OBJECTIVES: Endonasal endoscopic laser dacryocystorhinostomy is now a well established, effective approach to relieve nasolacrimal duct obstruction. Whereas attempts have been made to comment on the efficacy of the procedure, no study has been conducted to evaluate the acceptability of this procedure by those at the receiving end, ie, the patients. An attempt has been made in the present study to critically evaluate the procedure from the point of view of patients' acceptability and also to evaluate certain factors which may influence the success rate of this procedure. PATIENTS AND METHODS: Forty-six eyes from 40 patients underwent endonasal endoscopic laser dacryocystorhinostomy, performed by the same surgeon, over a period of 15 months. Various aspects of the procedure were evaluated by patients by filling out a simple questionnaire (Figure 1). In addition to recording patients' views, success of the procedure was confirmed by performing a postoperative sac washout in the clinic. Patients were also subdivided according to their age, duration of symptoms and history of previous surgical intervention. The data were statistically analysed using chi-square tests with the Yates correction. RESULTS: The percentage of patients who declared themselves completely cured was 65.22%. A partial resolution was felt by 23.91% of patients and no improvement was reported by 10.87% of patients. Forty-two out of the 46 eyes (91.3%) achieved anatomical success by the procedure, as shown by a postoperative sac washout performed in the clinic. Some of them, however, did not have complete resolution of their symptoms perhaps due to an additional factor of lacrimal pump dysfunction in these patients. During the procedure 60.86% of eyes felt no discomfort at all whereas 39.14% of eyes felt some discomfort at some point of time during the procedure (Table 1). When directly asked 86.12% of patients recommended the procedure (implying that the procedure had some good effect on their quality of life), 8.33% of patients did not recommend it and 5.55% of patients made no comments. Various factors affecting the success of this procedure were analysed (Table 2) and it was found that eyes which had no previous surgical intervention showed a complete cure rate which was significantly higher than that seen in eyes which had some sort of previous intervention (P = 0.0003); eyes with a short (<6 mths) duration of symptoms showed significantly higher success rates (P = 0.0098) in comparison to that shown by eyes with longer (>6 mths) duration of symptoms; and younger patients (<50 yrs) had a complete resolution rate much higher than patients over 50 yrs of age (P = 0.0309). CONCLUSION: The present study clearly shows that endonasal endoscopic laser DCR is an effective procedure, well tolerated and recommended by the patients. Discomfort during the procedure is not a major problem. Younger patients, with no previous surgical intervention and with short duration of symptoms are likely to be benefited the most. Though success rates are higher with external DCR, endonasal endoscopic laser DCR offers certain advantages over the external approach while keeping the option of external DCR open, if needed at a later date.

Comparison of procedures to determine electrical stimulation thresholds in cochlear implant users.

OBJECTIVE: This study was designed to evaluate threshold estimation procedures for cochlear implantees, both for clinical and research purposes. Precision and testing time of eight procedures were evaluated. These procedures included three variations of two adaptive tasks and two variations of an adjustment procedure. DESIGN: Electrical thresholds were obtained with eight different procedures. For each procedure, one of three tasks was combined with one of four decision strategies. With the adjustment task, current level was adjusted from "inaudible" to "just audible" or from "clearly audible" to "just audible." With the two adaptive tasks (i.e., "count the number of pulses" and "choose the interval with the pulse"), current level was adjusted during the sequence of trials by subjects' preceding responses according to three decision criteria (Levitt, 1971). Experimental data were collected on both an apical and a basal channel of six Laura cochlear implantees, and test-retest measures were obtained for each procedure, channel and subject. Moreover, total testing time was recorded in each test, to examine the trade-off with precision, and to investigate the feasibility of the procedures in a clinical setting. RESULTS: In general, the "count the pulses" procedures yield higher threshold values than the "choose the interval with the pulse" and adjustment procedures. Precision was not a statistically significant factor, although the test-retest variation was approximately a factor of 2 larger in the adjustment procedures than in the adaptive procedures. Test duration differences were large. Moreover, analyses of the adaptive procedures showed that a stable estimate requires at least six reversals and that the first four reversals should not be taken into account for threshold estimation. CONCLUSIONS: In a clinical setting, where precision and time are important parameters, precise thresholds can be obtained with the adjustment procedure. However, for research purposes, it is advised to use the "choose the interval with the pulse" task together with one of the transformed up-down decision criteria.
