Feasibility of conducting a lung-cancer chemoprevention trial among tin miners in Yunnan, P. R. China.

Tin miners in Yunnan Province in southern China have an extremely high rate of lung cancer, more than one percent per year among those at 'high risk' (40+ years old, with 10+ years of underground mining and/or smelting experience). The extraordinary lung cancer rates result from combined exposure to radon, arsenic, and tobacco smoking (cigarettes and/or bamboo water pipe). A study to determine the feasibility of conducting a large-scale, lung-cancer chemoprevention trial was conducted in 1986 among currently employed or retired miners from the Yunnan Tin Corporation in the city of Gejiu. The study was designed to answer four questions: (i) Could potentially eligible miners be identified and recruited? (ii) Could intervention agents be shipped successfully from the United States to the study area and be appropriately distributed? (iii) Would miners adequately adhere to the study protocol and comply with the intervention regimen? (iv) Could potential adverse effects be monitored and documented? The six-month feasibility study yielded affirmative answers to each of these questions. A roster of over 7,000 high-risk miners was compiled. Four agents (vitamin A, 25,000 IU; beta-carotene, 50 mg; vitamin E, 800 IU; and selenium, 400 micrograms) were administered daily with placebos to 350 miners according to a 2(4) factorial design. Adherence, assessed by pill counts and serum micronutrient levels, was approximately 90 percent. The findings from this preliminary study indicate that a full-scale, lung-cancer chemoprevention trial in this population is feasible.

The feasibility and value of using patient satisfaction ratings to evaluate internal medicine residents.

OBJECTIVE: To determine the feasibility and value of using patient satisfaction ratings to evaluate the physician-patient relationship skills of medical residents. DESIGN: A cross-sectional survey was used to collect patient satisfaction information for medical residents from all patients attending the out-patient teaching clinics over a three-month period. The feasibility of patient rating was assessed by evaluating the reliability of resident satisfaction scores and potential sources of bias in rating. The value of using this method was assessed by evaluating the proportion of variance in ratings attributable to residents, the prevalence of residents with ratings substantially below average, and the effect of training on patient satisfaction. SETTING: The medical clinics of two teaching hospitals at McGill University. PARTICIPANTS: 91 medical residents and clinical clerks, 1,003 patients, and 1,219 visit ratings. RESULTS: An average of 12.2 satisfaction ratings were collected per resident, providing a reliability of 0.56 (intraclass correlation) for resident satisfaction score. Adjustment for differences in patient populations would be necessary to obtain comparable scores among residents. Fifteen percent of the residents had a substantially greater proportion of poor and fair satisfaction ratings than the study average. Residents were responsible for a substantial proportion of the variance in clinic waiting time and patient satisfaction rating. Training appeared to have no effect on improving satisfaction scores, except among women residents. CONCLUSIONS: Patient satisfaction ratings provide valuable information about a resident's ability to establish an effective physician-patient relationship. However, the number of ratings required to obtain a reliable estimate of resident skill may limit the feasibility of using patient ratings as part of residency evaluation.

Feasibility of kangaroo mother care in Mumbai.

OBJECTIVE: The purpose of this study was to determine the feasibility and acceptability of kangaroo care in a tertiary care hospital in India. METHODS: A randomized controlled trial was performed over one year period in which 89 neonates were randomized into two groups kangaroo mother care (KMC) and conventional method of care (CMC). RESULTS: Forty-four babies were randomized into KMC group and 45 to CMC. There was significant reduction in KMC vs CMC group of hypothermia (10/44 vs 21/45, p-value < 0.01), higher oxygen saturations (95.7 vs 94.8%, p-value < 0.01) and decrease in respiratory rates (36.2 vs 40.7, p-value < 0.01). There were no statistically significant differences in the incidence of hyperthermia, sepsis, apnea, onset of breastfeeding and hospital stay in two groups. 79% of mothers felt comfortable during the KMC and 73% felt they would be able to give KMC at home. KMC is feasible, as mothers are already admitted in hospitals and are involved in the care of newborn. CONCLUSION: KMC is a simple and feasible intervention; acceptable to most mothers admitted in hospitals. There may be benefits in terms of reducing the incidence of hypothermia with no adverse effects of KMC demonstrated in the study. The present study has important implications in the care of LBW infants in the developing countries, where expensive facilities for conventional care may not be available at all place.

CT-guided lymphoscintigraphy in patients with squamous cell carcinoma of the head and neck: a feasibility study.

Accurate knowledge of lymphatic drainage facilitates planning of surgery for patients with squamous cell carcinoma of the head and neck. The aim of this study was to evaluate the feasibility of a new injection technique for lymph node detection in patients with squamous cell carcinoma of the hypopharynx and larynx, in whom simple peritumoural injection is hampered by the tumour localisation. Computed tomography (CT)-guided lymphoscintigraphy was performed in a total of 13 patients with squamous cell carcinoma of the hypopharynx and larynx who could not be injected by simple visual inspection. In a first step, contrast medium-enhanced axial 5-mm-thick CT slices of the neck were obtained. After tumour localisation on these CT images, 1-2 ml contrast medium and, in the event of appropriate distribution, subsequently 50 MBq technetium-99m colloid were injected at one to three peritumoural sites under CT guidance. Peritumoural tracer distribution was controlled by thin-slice CT. Subsequently, planar scintigrams from anterior, right and left lateral views were obtained. In all patients, peritumoural colloid application was feasible, as shown on control CT scans. Post injection, neither severe nor minor complications were noted. The patients complained of only low pain sensations with an average score of 1.8 on a pain scale from 0 to 10. Lymphatic drainage was identified in nine of the 13 patients, with a total of 14 detected lymph nodes. In six patients, ipsilateral sentinel lymph nodes were visualised; bilateral sentinel lymph nodes were identified in one patient and contralateral lymphatic drainage was observed in two patients. CT-guided lymphoscintigraphy is a feasible and minimally invasive diagnostic tool for sentinel lymph node detection in patients with squamous cell carcinoma of the hypopharynx and the larynx. In contrast to endoscopic colloid injection under general anaesthesia, this technique seems to be a well-tolerated method for lymphatic mapping prior to surgical procedures.

MRI for short-term follow-up of acute pulmonary embolism. Assessment of thrombus appearance and pulmonary perfusion: a feasibility study.

Tha aim of this study was to demonstrate the feasibility of MRI for short-term follow-up examinations in patients with acute pulmonary embolism (PE), and to assess temporal changes of pulmonary perfusion and thrombus characteristics that may be helpful in determining thrombus age. Thirty-three patients (15 female, 18 male, mean age 59.4 years) with acute PE were examined initially and 1 week later using both 16-row computed tomography (CT) and MRI with magnetic resonance angiography (MRA), real-time MRI and magnetic resonance (MR) pulmonary perfusion imaging. MRA and MR pulmonary perfusion used contrast-enhanced 3D flash sequences, and real-time MRI used true fast imaging with steady-state precession sequences (repetition time/echo time 3.1/1.5, bandwidth 975 Hz, 256 matrix size, acquisition time 0.4 s per image) in three orthogonal planes. Follow-up examinations were feasible for all patients. Diagnosis of PE was concordant between MRI and CT in all patients. The signal intensity of embolic material increased after 1 week for real-time MRI [132+/-5 vs. 232+/-22 (standard error of the mean), p<0.001], but not significantly for MRA. MR pulmonary perfusion of areas affected by PE increased (area under the curve initially 9.6+/-7.4, at follow-up 40.7+/-7.6, p<0.001). A decreasing time-to-peak in normal lung areas (15.7+/-0.96 and 13.2+/-0.55, respectively, p<0.05) indicated systemic circulatory effects of PE, and subsiding pulmonary artery obstruction improved arterial inflow for the entire lung. Follow-up examinations of patients with acute PE are feasible with MRI, and a relation between thrombus appearance and thrombus age can be implied.

Perfluorocarbon-perfused vitrectomy: a new method for vitrectomy--a safety and feasibility study.

PURPOSE: To evaluate the safety and feasibility of perfluorocarbon-perfused vitrectomy (PCPV) as a technique during vitrectomy for proliferative diabetic retinopathy (PDR) and rhegmatogenous retinal detachment (RRD). METHODS: In an experimental, prospective, noncomparative and interventional study, 28 eyes of 28 patients were submitted to vitrectomy with the PCPV technique, 18 eyes with PDR and 10 with RRD. In this technique we replaced the traditional balanced saline solution (BSS) in the infusion line (conventional vitrectomy) by perfluorocarbon liquids (PCL). Some patients with PDR were treated with oxygenated PCL. Clinical evaluation, electroretinography (ERG), and endothelial cell count (ECC) were used to assess the safety of this procedure. An arbitrary grading system (grades 0-5) was used to classify the surgery and maneuvers to assess feasibility. RESULTS: No eyes had a significant decrease in ECC, and the patients in whom we could obtain ERG postoperatively showed no significant differences from preoperative ERG. In the PDR group (using oxygenated and nonoxygenated PCL), 77.8% were graded 5/5; in the RRD group 90% were 5/5. PCPV allowed better visualization of vitreous and intraocular structures, rapid retinal reattachment, less blood in the vitreous cavity, subretinal fluid resolution, blood confinement, retinal stabilization, and easier dissection of epiretinal membranes. In all cases at least one surgical step was eliminated. CONCLUSIONS: PCPV in humans is a safe and feasible technique. Probably in selected cases the use of PCL offers several advantages over BSS, because of their properties (gravitational forces, immiscibility with bodily fluids, and ability to transport oxygen). Prospective and comparative studies are necessary to establish formal indications and possible contraindications.

Impact of prior surgery on the feasibility of laparoscopic surgery for children: a prospective study.

BACKGROUND: This study aimed to determine the impact of prior surgery on the feasibility of laparoscopic surgery for children. METHODS: A prospective study analyzed 471 consecutive children who underwent laparoscopic surgery over a 4-year period. Laparoscopic procedures were classified "easy," "difficult," or "demanding." The end points of the study were conversion rate, intraoperative events, and duration of operation. RESULTS: A total of 89 patients (19%) had undergone previous abdominal surgery. The conversion rate was 18% for the patients with prior surgery versus 9% for those without a prior operation (16/89 vs 35/382; p < 0.05). This difference reflects a significantly higher conversion rate for "easy" procedures among patients with than among those without prior surgery, but not for "difficult" and "demanding" procedures. The type of prior surgery had no significant impact on the mean duration of the operation. Of 71 procedures, 12 (17%) after prior conventional surgery were converted, as compared with 4 (22%) of 18 after prior laparoscopy (p > 0.05). Intraoperative events, mainly attributable to adhesions and lack of overview, occurred in 8% of patients with prior procedures, as compared with 2% without former surgery (7/89 vs 9/382; p < 0.05). Relevant complications were not significantly more frequent after prior surgery. The incidence of conversions decreased with increased time between current and previous surgery. It was 64% for surgeries less than 1 year later, 25% for surgeries 1 to 5 years later, and 5% for surgeries more than 5 years later (7/11 vs 6/24 vs 3/54; p < 0.001). CONCLUSIONS: Prior surgery has a limited impact on the feasibility of laparoscopic surgery for children. The conversion rate and the incidence of intraoperative events, mainly because of adhesions and lack of overviewing, is increased, but not the incidence of relevant complications. The feasibility improves considerably with increased time between surgery and prior surgery. The authors consider laparoscopy to be the first-choice technique after prior surgery.

Reducing the unmet needs of patients with colorectal cancer: a feasibility study of The Pathfinder Volunteer Program.

GOALS OF THE WORK: Many cancer patients experience unmet needs and elevated levels of anxiety and depression. This paper describes a volunteer-delivered intervention to reduce the psychosocial needs of cancer patients and presents findings from a feasibility study of this intervention. MATERIALS AND METHODS: The telephone-based intervention, called the Pathfinder Program, involves the assignment of volunteers to patients to assist them in addressing their needs as identified in questionnaires. Fifty-two patients with colorectal cancer were involved in the feasibility study, with 18 in the intervention. Sixty-two percent of the sample was male and the mean age was 64 years. Patients' needs were assessed using The Supportive Care Needs Survey, a colorectal cancer symptom checklist, and the Hospital Anxiety and Depression Scale. All patients completed baseline questionnaires (Time 1) and 47 completed Time 2 questionnaires 3 months later. MAIN RESULTS: The most common needs were fear of the cancer spreading and returning, concerns about the worries of others, gas or wind, changes in weight, and bowel problems such as diarrhea, constipation, and pain. A statistically significant Time 1 to Time 2 decrease in supportive care needs and depression was found for the intervention group. CONCLUSIONS: The Pathfinder Program has been found to be feasible, acceptable for patients, and has the potential to reduce needs and depression. A larger, randomized controlled trial is needed to determine the impact of this program on colorectal symptoms and anxiety.

Feasibility of hanging maneuvers in orthotopic liver transplantation with inferior vena cava preservation and in liver surgery.

BACKGROUND/PURPOSE: The aim of this work was to study the feasibility and complication rates of liver hanging maneuvers: the Belghiti liver hanging maneuver (BLHM) in liver resection and the modified liver hanging maneuver (MLHM) in orthotopic liver transplantation (OLT) with inferior vena cava (IVC) preservation. METHODS: From January 2001 to August 2003, BLHM was planned in 26 consecutive right hepatectomies and MLHM in 28 consecutive OLTs with IVC preservation. RESULTS: BLHM was performed in 24/26 patients (92%). In the 2 remaining patients, chronic biliary infection (n = 1) and intraparenchymal hemorrhagic hepatocellular carcinoma (n = 1) did not allow BLHM to be achieved. Bleeding during the BLHM procedure occurred in 1 patient (4%), with no need for interruption. MLHM was performed in all 28 patients, and in none of them was bleeding observed during the maneuver. CONCLUSIONS: BLHM and MLHM are important technical refinements with several advantages. Feasibility rates were 92% and 100%, respectively. Bleeding risk remained low (4%) for BLHM and was 0% for MLHM. The rate of BLHM failure suggests that the feasibility rate may be higher in normal liver parenchyma.

Unknown primary carcinoma: a feasibility assessment of combination chemotherapy with cisplatin and docetaxel.

BACKGROUND: Docetaxel (Taxotere) and cisplatin are two of the most active single agents used in the treatment of solid tumors. We examined the feasibility of using a combination of docetaxel and cisplatin for the treatment of unknown primary carcinoma in order to prepare a larger scale prospective study. METHODS: Eligible patients were aged 18 to 75 years, with an Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less and a life expectancy of 8 weeks or more, and had been diagnosed as having unknown primary carcinoma by the required examinations. Patients were not permitted to have received prior chemotherapy and had to have measurable lesions. Docetaxel (60 mg/m(2)) was given intravenously over a 1-h period immediately before cisplatin (80 mg/m(2)), which was given intravenously over a 2-h period, every 3 weeks. Premedication included dexamethasone, granisetron, and standard hyperhydration. RESULTS: Twenty-six treatment courses in five patients were tested according to the protocol and feasibility was assessed. Adverse events observed included grade 4 neutropenia, leukopenia, grade 3 nausea/vomiting, grade 2 diarrhea, and mucositis. These adverse events were well tolerated, reversible, and manageable. Doses were not reduced and all injections were given or their due date without any delay in all patients. Four patients achieved a partial response and one had stable disease. CONCLUSION: Treatment of patients with unknown primary carcinoma with a combination of docetaxel and cisplatin is feasible. Conduct of a phase II trial of this regimen is warranted.

An assessment of the feasibility and utility of the MS symptom and impact diary (MSSID).

The Multiple Sclerosis Symptom and Impact Diary (MSSID) was developed to provide a more comprehensive assessment of the impact of multiple sclerosis (MS) on HRQoL for use in clinical practice. This paper reports on an assessment of its feasibility and utility in two outpatient samples of people with MS (n = 13 and n = 63) using quantitative and qualitative methods. The response rate in study 2 was 82% and 83% of days were fully completed. Most respondents found the MSSID easy to understand and got into the habit of completing it. Missing items increased over time and those who experienced a relapse had more missing items than those who did not but there was no difference in the number of missed days. Some respondents found completing the MSSID enabled them to manage their lives more effectively and provided useful information to their neurologist. It is concluded that the MSSID is feasible for people with MS to complete and some may find the MSSID helpful as a tool to monitor their condition. Further research is needed to examine clinicians' perceptions of the feasibility and utility of the MSSID within clinical practice.

US-Canada Great Lakes Regional Specimen Bank Feasibility Study.

A study to examine the feasibility of establishing a Regional Specimen Bank in the Great Lakes area of the United States and Canada has recently been initiated by the Michigan Audubon Society. There are several existing formal and informal specimen banking facilities active in the region but their combined adequacy has not been evaluated. This feasibility study will establish the need and use of a regional bank and the institution(s) necessary to satisfy this need will be recommended. The study will address the scope required to meet present and future needs including the types of specimens to be represented in the bank, geographic coverage and protocols for collection, shipping, processing, analysis and storage. A management policy of the bank will be developed encompassing business operation, costs, governing structure and personnel requirements. The legal requirements of the bank will be determined with regards to the acquisition of samples, transport across national boundaries, access to specimens and information, and liability during operation. An effective information dissemination network will be recommended that is compatible with national and international partners, will facilitate technology and information transfer and support the quality and status of the bank. Determination of secure, long-term funding sources will be one of the key elements to ensuring a safe repository. This feasibility study is funded by the Great Lakes Protection Fund.

Feasibility of a computerized alcohol screening and personalized written advice in the ED: opportunities and obstacles.

This study evaluates the feasibility of a computerized alcohol screening and intervention in patients seeking care at an emergency department. The aim of the study was to explore prevailing attitudes among nursing staff to alcohol prevention in general and the computerized screening concept before the introduction of the computerized screening procedure. Interviews were performed with six nursing staff members and a written questionnaire applied to all staff participating in training before the implementation of the concept. Observation was done in order to evaluate how the screening was performed and implemented in order to gain more knowledge about possible obstacles to alcohol screening at an emergency department. The project concept of computerized screening and low staff involvement was found to be a feasible way to overcome organizational barriers such as time limitation but there were still important attitudinal barriers among staff; thus a great disparity in practices between different staff members was observed. The results suggest that it is possible, given the time limitation, to include a computerized screening and intervention in the routines of an emergency department, when the staff regard prevention as part of their responsibilities. The findings provide evidence about the acceptability by nursing staff and feasibility of a computerized screening and personalized print out as feed back to the patients.

Feasibility and applicability of paramedic-based prehospital fibrinolysis in a large North American center.

BACKGROUND: Although considered the highest level of evidence and critical-to-test novel therapies, clinical trials are unrepresentative of the "real world" as they lack a true patient denominator, which limits general applicability of results. Accordingly, in conjunction with the Assessment of the Safety and Efficacy of a New Thrombolytic Regimen 3+ trial, we evaluated a comprehensive contemporary cohort of patients with ST segment elevation myocardial infarction (STEMI) to investigate: feasibility, applicability, safety, and efficacy of de novo paramedic-based prehospital fibrinolysis (PHF) program. METHODS: Prospective observational comparative cohort of all patients with STEMI encountered during the Assessment of the Safety and Efficacy of a New Thrombolytic Regimen 3+ enrollment period. Time-to-treatment, systematic electrocardiographic (ECG) analysis, peak creatine kinase, inhospital clinical events, and mortality were assessed. RESULTS: During the 22-month study period, 1095 patients with STEMI were admitted to hospital; 46% (119/258) of eligible patients received PHF (< or = 6 hours of symptom onset by ambulance). Paramedics contacted the study physician 3.6 times per week: 33% (119/357) of patients enrolled, and ECG transmission failure is 6%. Time-to-treatment was reduced with PHF versus inhospital (1 hour 43 minutes vs 2 hours 38 minutes; P < .001). Despite higher baseline Thrombolysis in Myocardial Infarction Scores and greater ECG territory at risk (ST), prehospital patients achieved more favorable outcomes: peak creatine kinase (1413 vs 1549 U/L; P = .122), Q wave at discharge (56.3% vs 70.7%; P = .003), and intracranial hemorrhage (0% vs 0.8%; P < 1.0), respectively. Inhospital mortality for PHF versus inhospital patients was 3.4% versus 4.8% (P = .627), with an adjusted odds ratio of 0.60 (confidence interval, 0.19-1.87). CONCLUSION: Feasibility and applicability of PHF was demonstrated with a substantial reduction in treatment delay and favorable clinical outcomes. Extending the unrealized potential of paramedic-based PHF programs in North America is feasible and desirable.

[Novel Doppler indexes of estimation of pulmonary capillary pressure: influence of age, feasibility in the acute setting and reproducibility].

BACKGROUND: The Doppler indexes E/Vp, E/Ea, 1000/(2 x IRT + Vp), 1000/(2 x IRT + Ea) and DTd (E: peak E mitral velocity; Vp: flow propagation velocity by color M-mode; Ea: peak early diastolic velocity at lateral mitral annulus by tissue Doppler; IRT: isovolumic relaxation time; DTd: deceleration time of the pulmonary venous diastolic wave) have been proposed for the non-invasive prediction of left ventricular filling pressures. However, the influence of age, the feasibility in acute setting and the reproducibility of these Doppler indexes have never been simultaneously investigated. OBJECTIVE: The present study was conducted to evaluate the influence of age in 56 healthy subjects (57 +/- 20 years of age), the feasibility in 40 critically ill patients (72 +/- 13 years of age; 21 with decompensated heart failure) and the reproducibility in 15 patients. RESULTS: Only the indexes E/Vp (R = 0.37, P = 0.005) and E/Ea (R = 0.72, P < 0.001) were correlated with age. The feasibility was 92, 90, 72, 72 and 45% for E/Ea, 1000/(2 x IRT + Ea), E/Vp, 1000/(2 x IRT +Vp) and DTd, respectively. The best reproducibility was observed for the Doppler parameters E and Ea. CONCLUSION: Despite it is influenced by age, E/Ea appears to be the most useful index for predicting left ventricular filling pressures routinely.

Telephone self-monitoring among alcohol use disorder patients in early recovery: a randomized study of feasibility and measurement reactivity.

Frequent symptom self-monitoring protocols have become popular tools in the addiction field. Interactive Voice Response (IVR) is a telephone monitoring system that has been shown to be feasible for collecting frequent self-reports from a variety of research populations. Little is known, however, about the feasibility of using IVR monitoring in clinical samples, and few controlled trials exist assessing the impact of any type of frequent self-report monitoring on the behaviors monitored. This pilot study with patients in early recovery from an alcohol use disorder (n=98) evaluated compliance with two IVR monitoring protocols, subjective experiences with monitoring, and change in symptoms associated with monitoring (i.e., measurement reactivity). Participants were randomly assigned to call an IVR system daily for 28 days, once per week for 4 weeks, or only to complete 28-day follow-up assessment including retrospective drinking reports. Monitoring calls assessed alcohol craving, substance use, emotional well-being, and PTSD symptoms. Most monitoring participants completed calls on at least 75% of scheduled days (72.2% and 59.2% for daily and weekly, respectively). Including reconstructed data from follow-up of missed calls yielded 77.8% and 74.1% of maximum data points, respectively. Most monitoring participants indicated the protocol was manageable and reported positive or no effects of monitoring on urges to use alcohol, actual drinking, and PTSD symptoms. Analyses of measurement reactivity based on assessment one month after randomization found no significant group differences on drinking, craving for alcohol, or PTSD-related symptoms. Results suggest that IVR technology is feasible and appropriate for telephone symptom monitoring in similar clinical samples.

Laparoscopic extraperitoneal adenomectomy (Millin): pilot study on feasibility.

OBJECTIVE: The aim of the present work is to describe the surgical technique and to assess the feasibility of laparoscopic extraperitoneal adenomectomy in a pilot study. METHODS: Eighteen consecutive patients in whom an open adenomectomy was planned were operated on in a laparoscopic extraperitoneal fashion. In all patients indication was based on objective signs of obstruction. The laparoscopic approach was standard in all cases as follows: creation of a preperitoneal workspace, haemostatic control of lateral venous vesicoprostatic pedicles, transversal anterior incision of the prostate capsule, progressive enucleation of the adenoma with the help of an harmonic scalpel, suture of the posterior bladder neck to the prostate fossa, closure of the prostate capsule, and retrieval of the specimen. Feasibility was assessed by objective operative parameters (reconversion, operating time, and blood loss and transfusion requirements) and per operative complications. Data on short term follow-up are also available. RESULTS: Mean age of the patients was 67.8 years (S.D. 6.2) and mean prostatic weight calculated by TRUS 95.1cm(3) (S.D. 28.1). Mean maximal flow (Q(max)) was 4.3ml/s (S.D. 3.4) with four patients (22.2%) presenting in retention. Mean duration of intervention was 145min (S.D. 32.5) and mean blood loss 192ml (S.D. 178). Mean excised tissue was 47.6g (S.D. 30). Neither conversions to open prostatectomy nor transfusions were required. The urethral catheter remained in place an average of 3.0 days (S.D. 2.4) in 14 patients, while 4 needed a re-catheterization. Mean postoperative hospital stay was 5.9 days (S.D. 5.5). Five patients (27.7%) presented complications during follow-up, mild in most of the cases but one who required a secondary intervention for persistent obstruction. CONCLUSIONS: Laparoscopic extraperitoneal adenomectomy (Millin's procedure) is feasible with a reasonable complication rate. Although comparison with open adenomectomy is not yet available, this technique might have potential advantages in terms of blood loss and postoperative catheter time.

A multimedia psychosocial support program for couples receiving infertility treatment: a feasibility study.

OBJECTIVE: To develop and test the feasibility of a theory-driven, psychosocial support CD-ROM prototype for couples in infertility treatment. DESIGN: Focus group meetings with reproductive health experts, semistructured interviews with infertility patients, and content analysis of an infertility message board to determine content domains of the CD-ROM. Usability and acceptance testing of prototype CD-ROM based on predetermined feasibility criteria. SETTING: Private offices and fertility centers. PATIENT(S): Expert panel of 5 reproductive health specialists; interviews with 62 individuals with infertility (35 women, 27 men); feasibility study with 12 patients and 12 experts in reproductive medicine and infertility support. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Product usability/acceptance test. RESULT(S): Participant feedback and content analysis informed the development of a prototype patient education CD-ROM that uses audio, video, interactive tasks, and personalized feedback. Over 80% of participants successfully completed usability tasks, and over 90% rated prototype satisfaction as "good" to "excellent." Some areas were noted for improvement in navigation and refinement in delivery of instructions. Results strongly indicate an interest in an infertility multimedia support tool. CONCLUSION(S): Multimedia methods may serve as an effective, innovative psychosocial intervention for infertility patients and overcome barriers of limited local access to educational and support services.
