[Preventive antibiotic administration for prevention of nosocomial septicemia in very small premature infants (VLBW infants)--preventive vancomycin administration against infections with coagulase negative streptococci--prevention of translocation with oral cefixime therapy in intestinal colonization with pathogenic gram-negative pathogens].

VLBW-infants below 1500 g of birth weight have a quite high risk to acquire a nosocomial sepsis. 20-40% of all infants exhibit signs of nosocomial infection once during neonatal intensive care. The rate of infection is related to technique and amount of used invasive devices as to gestational age. Coagulase-negative staphylococci (CONS) and gram-negative organisms contribute most to these cases of sepsis. In a three phase study we tried to demonstrate the efficacy of different mechanisms to change the rate of nosocomial sepsis. During the first phase a strict hygienical protocol was enforced as isolation, care with sterile gloves and aseptic techniques in introducing and maintaining i.v. lines. In a second phase we started a randomized controlled study of prophylactic vancomycin (10 mg/kg/day in two doses). In a third phase we added an oral antibiotic regime with cefixime for all patients with positive cultures for gramnegative organisms under the hypothesis of translocation from the gut as the way of infection. During the first phase 23.7% of 76 patients enrolled acquired CONS-sepsis, 0.52% gramnegative sepsis. During the second phase (41 patients) 6 patients in the control group acquired CONS-sepsis, none in the vancomycin-group. The rate of gramnegative infections was not different (4 and 3 cases). During the third phase (vancomycin plus cefixime eventually in cases of positive stool cultures) no case of nosocomial sepsis occurred (35 patients, 11 positive cultures). The management used in phase 3 reduced the rate of nosocomial infections in VLBW-infants drastically.

Antibiotics versus placebo for prevention of postoperative infection after appendicectomy.

BACKGROUND: Appendicitis is the most common cause of acute abdominal pain requiring surgical intervention. The cause of appendicitis is unclear and the mechanism of pathogenesis continues to be debated. Despite improved asepsis and surgical techniques, postoperative complications, such as wound infection and intraabdominal abscess, still account for a significant morbidity. Several studies implicate that postoperative infections are reduced by administration of antimicrobial regimes. OBJECTIVES: The objective of this review is to compare the use of antibiotics with placebo or no treatment in patients undergoing appendectomy. Will these patients benefit from antimicrobial prophylaxis? The outcomes are described according to the nature of the appendix, as either simple appendicitis (including the non-infectious stage) and complicated appendicitis. This review do not attempt to compare the effect of different regimens, a clinical question that is addressed in another review undertaken by this Group (CCCG). SEARCH STRATEGY: We searched The Cochrane Controlled Trials Register (Cochrane Library 2000 issue 4), Medline (January 1966 to September 2000), Embase and the Cochrane Colorectal Cancer Group specialised register (September 2000). In addition we manually searched the reference lists of the primary identified trials. SELECTION CRITERIA: Randomised Controlled Trials (RCT) and Controlled Clinical Trials (CCT) in which any antibiotic regime were compared to placebo in patients suspected of having appendicitis undergoing appendectomy were evaluated. Both studies on children and adults were reviewed. The outcome measures of the studies were either wound infection, intraabdominal abscess, length of stay in hospital or mortality. DATA COLLECTION AND ANALYSIS: Eligibility and trial quality were assessed, recorded and cross-checked by to reviewers. MAIN RESULTS: Forty-four studies including 9298 patients were included in this review. The overall result is that use of antibiotics is superior to placebo for the outcome wound infection and intraabdominal abscess, with no apparent difference in the nature of the removed appendix. Studies exclusively on children and studies examining topical application reported results in favour to the above although the results were not significant. REVIEWER'S CONCLUSIONS: Antibiotic prophylaxis is effective in the prevention of postoperative complications in appendectomised patients, whether the administration are given pre-, per- and post-operatively and could be considered for routine in emergency appendectomies.

Can hypertension be prevented? The Danish Hypertension Prevention Project and the Trial of Prevention of Hypertension studies.

Essential hypertension, a major health problem worldwide, is a disease generally considered to require life-long treatment. However, evidence suggests that hypertension is caused by specific phenotypic changes caused by the combination of genetic and environmental factors. Thus, in principle, hypertension could be prevented by prevention of these phenotypic changes. Animal data indicate that early treatment that blocks the renin-angiotensin system have long-term effects after treatment withdrawal. Here we report on two human trials that are testing whether early treatment (with the AT1-antagonist, candesartan) is able to have a persistent effect after stopping treatment: the Danish Hypertension Prevention Project and Trial of Prevention of Hypertension.

Preventive health care, 1999 update: prevention of oral cancer mortality. The Canadian Task Force on Preventive Health Care.

BACKGROUND: Approximately 3,000 new cases of oral cancer are diagnosed each year in Canada. Most of these cases occur among older adults with a history of tobacco use or excessive alcohol consumption. Preventive interventions for oral cancer include counselling of patients to modify risk factors and screening to identify precancerous and early-stage lesions. This report presents evidence-based guidelines on the prevention of oral cancer and precancer among asymptomatic patients. METHODS: Literature searches of the 1966-1999 MEDLINE and CANCERLIT databases were completed using the major MeSH heading mouth neoplasms. References from articles and recommendations of organizations were also reviewed. The evidence-based methods of the Canadian Task Force on Preventive Health Care were used to assess evidence and to develop guidelines. Advice from experts and other recommendations were taken into consideration. RESULTS: In cohort and case-control studies, smoking cessation decreased the risk of oral cancer and precancer. Randomized controlled trials (RCTs) indicate counselling by trained health care professionals is effective in promoting smoking cessation. Although counselling has been effective for the reduction of excessive alcohol consumption in RCTs, no studies have examined whether alcohol reduction reduces the risk of oral cancer or precancer. The usefulness of general population screening is limited by the low prevalence and incidence of the disease, the potential for false-positive diagnoses and the poor compliance with screening and referral. There is no evidence that screening of the general population or high-risk groups leads to a reduction in mortality or morbidity from oral cancer. INTERPRETATION: There is good evidence to specifically consider smoking cessation counselling in a periodic health examination (grade A recommendation). For population screening, there is fair evidence to specifically exclude screening for oral cancer (grade D recommendation). For opportunistic screening during periodic examinations, there is insufficient evidence to recommend inclusion or exclusion of screening for oral cancer (grade C recommendation). For patients at high risk, annual examination by physician or dentist should be considered. Risk factors include tobacco use and excessive consumption of alcohol. These recommendations are similar to those made by the Canadian Task Force on the Periodic Health Examination in 1994 and by the U.S. Preventive Services Task Force in 1996.

Preventive care in the emergency department, Part I: Clinical preventive services--are they relevant to emergency medicine? Society for Academic Emergency Medicine Public Health and Education Task Force Preventive Services Work Group.

In 1998 the Society for Academic Emergency Medicine's (SAEM's) Board of Directors asked the SAEM Public Health and Education Task Force to develop recommendations for prevention, screening, and counseling activities to be conducted in emergency departments (EDs). The Task Force's work was divided into two phases: 1) a discussion of the rationale for preventive services in the ED, along with generation of a preliminary list of prevention activities that could be studied for ED implementation; and 2) a formal evidence-based review of topics chosen from the preliminary list, along with recommendations for ED implementation and further study. This paper represents Phase I of the project. Phase II, the formal evidence-based review and recommendations, is published separately in this issue.

Nasal continuous positive airways pressure immediately after extubation for preventing morbidity in preterm infants.

BACKGROUND: Preterm infants being extubated following a period of intermittent positive pressure ventilation via an endotracheal tube are at risk of developing respiratory failure as a result of apnea, respiratory acidosis and hypoxia. Nasal continuous positive airway pressure appears to stabilise the upper airway, improve lung function and reduce apnea and may therefore have a role in facilitating extubation in this population. OBJECTIVES: In preterm infants having their endotracheal tube removed following a period of intermittent positive pressure ventilation (IPPV), does management with nasal continuous positive airways pressure (NCPAP) lead to an increased proportion remaining free of additional ventilatory support, compared to extubation directly to headbox oxygen? SEARCH STRATEGY: Searches were made of the Oxford Database of Perinatal Trials, Medline, previous reviews including cross references, abstracts of conferences and symposia proceedings, expert informants, journal handsearching mainly in the English language and expert informant searches in the Japanese language by Prof. Ogawa. SELECTION CRITERIA: All trials utilising random or quasi-random patient allocation, in which NCPAP (delivered by any method) was compared with headbox oxygen for post-extubation care were included. Methodological quality was assessed independently by the two authors. DATA COLLECTION AND ANALYSIS: Data were extracted independently by the two authors. Prespecified subgroup analysis to determine the impact of different levels of NCPAP, differences in duration of IPPV and use of aminophylline were also performed using the same package. MAIN RESULTS: Nasal CPAP, when applied to preterm infants being extubated following IPPV, reduces the incidence of adverse clinical events (apnea, respiratory acidosis and increased oxygen requirements) indicating the need for additional ventilatory support. A reduction in the incidence of chronic lung disease at 28 days of age is also seen in the group extubated to NCPAP. REVIEWER'S CONCLUSIONS IMPLICATIONS FOR PRACTICE: nasal CPAP is effective in preventing failure of extubation and reducing oxygen use at 28 days of life in preterm infants following a period of endotracheal intubation and IPPV. Implication for research: further definition of the patient gestational age and weight groups in whom these results apply is required. Optimal levels of NCPAP as well as methods of administration remain to be determined.

Reduced dietary salt for prevention of cardiovascular disease.

BACKGROUND: Restricting sodium intake in elevated blood pressure over short periods of time reduces blood pressure. Long term effects (on mortality, morbidity or blood pressure) of advice to reduce salt in patients with elevated or normal blood pressure are unclear. OBJECTIVES: To assess in adults the long term effects (mortality, cardiovascular events, blood pressure, quality of life, weight, urinary sodium excretion, other nutrients and use of anti-hypertensive medications) of advice to restrict dietary sodium using all relevant randomised controlled trials. SEARCH STRATEGY: The Cochrane Library, MEDLINE, EMBASE, bibliographies of included studies and related systematic reviews were searched for unconfounded randomised trials in healthy adults aiming to reduce sodium intake over at least 6 months. Attempts were made to trace unpublished or missed studies and authors of all included trials were contacted. There were no language restrictions. SELECTION CRITERIA: Inclusion decisions were independently duplicated and based on the following criteria: 1) randomisation was adequate; 2) there was a usual or control diet group; 3) the intervention aimed to reduce sodium intake; 4) the intervention was not multifactorial; 5) the participants were not children, acutely ill, pregnant or institutionalised; 6) follow-up was at least 26 weeks; 7) data on any of the outcomes of interest were available. DATA COLLECTION AND ANALYSIS: Decisions on validity and data extraction were made independently by two reviewers, disagreements were resolved by discussion or if necessary by a third reviewer. Random effects meta-analysis, sub-grouping, sensitivity analysis and meta-regression were performed. MAIN RESULTS: Three trials in normotensives (n=2326), five in untreated hypertensives (n=387) and three in treated hypertensives (n=801) were included, with follow up from six months to seven years. The large, high quality (and therefore most informative) studies used intensive behavioural interventions. Deaths and cardiovascular events were inconsistently defined and reported; only 17 deaths equally distributed between intervention and control groups occurred. Systolic and diastolic blood pressures were reduced at 13 to 60 months in those given low sodium advice as compared with controls (systolic by 1.1 mm Hg, 95% CI 1.8 to 0.4, diastolic by 0.6 mm hg, 95% CI 1.5 to -0.3), as was urinary 24 hour sodium excretion (by 35.5 mmol/ 24 hours, 95% CI 47.2 to 23.9). Degree of reduction in sodium intake and change in blood pressure were not related. People on anti-hypertensive medications were able to stop their medication more often on a reduced sodium diet as compared with controls, while maintaining similar blood pressure control. REVIEWER'S CONCLUSIONS: Intensive interventions, unsuited to primary care or population prevention programmes, provide only minimal reductions in blood pressure during long-term trials. Further evaluations to assess effects on morbidity and mortality outcomes are needed for populations as a whole and for patients with elevated blood pressure. Evidence from a large and small trial showed that a low sodium diet helps in maintenance of lower blood pressure following withdrawal of antihypertensives. If this is confirmed, with no increase in cardiovascular events, then targeting of comprehensive dietary and behavioural programmes in patients with elevated blood pressure requiring drug treatment would be justified.

Cost-effectiveness of screening for albuminuria with subsequent fosinopril treatment to prevent cardiovascular events: A pharmacoeconomic analysis linked to the prevention of renal and vascular endstage disease (PREVEND) study and the prevention of renal and vascular endstage disease intervention trial (PREVEND IT).

OBJECTIVE: This study estimated the cost-effectiveness,from the Dutch health care perspective, of screening for albuminuria in the general Dutch population to prevent cardiovascular events (CVEs) with subsequent angiotensin-converting enzyme inhibitor treatment, using data from the Prevention of REnal and Vascular ENdstage Disease Intervention Trial (PREVEND IT). METHODS: PREVEND IT was a single-center, double-blind, randomized, placebo-controlled trial with a 2 x 2 factorial design within the larger observational Prevention of REnal and Vascular ENdstage Disease (PREVEND) study. The PREVEND IT study was conducted to assess the effects of fosinopril 20 mg and pravastatin 40 mg on CVEs in subjects with specific inclusion criteria: urinary albumin excretion (UAE) rate in the range from 15 to 300 mg/d, blood pressure <160/100 mm Hg, and plasma cholesterol level <8.0 mmol/L. Cost-effectiveness estimates for the Dutch population were expressed in euros (2002; 1 euro = US 1.01 dollars) as net costs per life-year gained (LYG) in the baseline and sensitivity (stochastic) analyses. RESULTS: Data were assessed for 864 subjects, with a mean (SD) follow-up of 46 (7) months. CVEs occurred in 45 (5.2%) subjects. Subjects who received fosinopril had a 40% lower incidence of CVEs than subjects in the placebo group (3.9% vs 6.5%, respectively; P = NS). The cost-effectiveness of screening for albumnuria was determined to be euro 16,700/LYG for the study population. Stochastic analysis indicated that the probability of the cost-effectiveness being below the suggested Dutch threshold of euro 20,000/LYG was 59% in the baseline analysis. The probability of cost-effectiveness below euro 20,000/LYG would increase to 91% if only subjects with UAE >50 mg/d were treated with fosinopril. Limiting the screening to subjects aged >50 years and >60 years also improved cost-effectiveness. CONCLUSIONS: The results of our study suggest that screening the general Dutch population for albuminuria and subsequently treating those found positive with fosinopril may be cost-effective compared with no screening and adopting the Dutch health care perspective. However, confirmation from larger multicenter trials is needed.

Centers for Disease Control and Prevention injury research agenda: identification of acute care research topics of interest to the Centers for disease Control and Prevention--National Center for Injury Prevention and Control.

BACKGROUND: The purpose of this report is to identify the most important research questions pertaining to the acute care of the injured patient using a Web-based Delphi technique to achieve expert opinion consensus. METHODS: Experts in trauma care from the United States and Canada (n =39) generated structured research questions and then ranked these questions in order of importance, using a Web-based survey for question generation, question ranking, and a Delphi technique of consensus. Guidelines for question construction and ranking specified that participants considered questions that fall within the interest and domain of the Centers for Disease Control (CDC)-National Center for Injury Prevention and Control (NCIPC). RESULTS: One hundred thirty-seven questions in 18 distinct categories of interest were initially generated. After two rounds of merging, collating, reassessing, and ranking by significance and importance, 25 research questions were deemed most important and significant in the care of the injured patient. Ten of these (40%) were considered to be appropriate issues for the CDC-NCIPC to address and fund, dealing with injury prevention strategies, trauma systems design and funding, the epidemiology of injury, and global outcome determinants. These 25 questions were also reviewed with consideration given to the most likely source of federal funding of investigations. CONCLUSION: This report identifies the areas of trauma care in which research efforts might best be directed. Fully 40% of the key research questions could be considered to fall under the interest and auspices of the CDC-NCIPC. The remaining questions cover a broad range of topics and likely funding sources, emphasizing the need for a coordinated oversight of research funding in trauma care.

Prostaglandins for prevention of postpartum haemorrhage.

BACKGROUND: Prostaglandins have mainly been used for postpartum haemorrhage when other measures fail. Misoprostol, a newer and cheaper prostaglandin E1 analogue, has sometimes been used for management of the third stage of labour. OBJECTIVES: The objective of this review was to assess the effects of prophylactic prostaglandin use in the third stage of labour. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register were searched. Researchers in the field were also contacted. Date of the latest search: December 1999. SELECTION CRITERIA: Randomized or quasi-randomized trials comparing a prostaglandin agent with another uterotonic or no prophylactic uterotonic (nothing or placebo) as part of management of the third stage of labour. DATA COLLECTION AND ANALYSIS: Eligibility and trial quality was assessed by one reviewer. MAIN RESULTS: Seven trials were included. There were six trials of injectable prostaglandins and one of rectal misoprostol. The main limitations of these studies are their small sample sizes and lack of blind assessment of the outcomes. Injectable prostaglandins were associated with decreased blood loss (weighted mean difference -72 millilitres, 95% confidence interval -70 to -75) and shortened duration of third stage when compared to other uterotonics. Severe postpartum haemorrhage (1000 millilitres or more blood loss) occurred in two of four studies and was seen in fewer women receiving prostaglandins, though the difference was not statistically significant. Adverse effects (vomiting, diarrhoea and abdominal pain) were more common with prostaglandins when compared to other uterotonic agents. REVIEWER'S CONCLUSIONS: Although injectable prostaglandins appear to be effective in preventing postpartum haemorrhage, concerns about safety and costs limit their suitability for routine prophylactic management of third stage of labour. However, injectable prostaglandins should continue to be used for the treatment of postpartum haemorrhage when other measures fail. Misoprostol is cheap, stable and seems to be safe. Trials addressing the effectiveness of misoprostol are continuing.

Putting prevention into practice. Impact of a multifaceted physician education program on preventive services in the inner city.

BACKGROUND: Physicians' prevention practices often differ from guidelines published by national authorities. Effective preventive services are most needed in inner city settings that suffer disproportionately from preventable diseases. This study examined the impact of a multifaceted physician prevention education program on the provision of preventive services in an inner city municipal hospital. METHODS: The study used a controlled intervention comparative design at two inner city municipal hospitals--Harlem Hospital Center, New York, NY (intervention site) and Kings County Hospital, Brooklyn, NY (comparison site)--serving predominantly African-American patient populations. The intervention site received prototype materials for physicians, patients, and the office setting from the US Public Health Service's Put Prevention Into Practice campaign and a series of prevention lectures from November 1991 through April 1992. Change in physician prevention practices and knowledge was assessed by self-administered questionnaires and change in patients' reports of preventive services received was assessed by structured interviews. RESULTS: Physicians at Harlem Hospital Center reported a greater postintervention increase in prevention practices and demonstrated a greater increase in prevention knowledge in comparison with physicians at Kings County Hospital. Patients at Harlem Hospital Center reported receiving increased preventive services from physicians after the intervention, while patients at Kings County Hospital did not report any significant change in preventive services received. CONCLUSIONS: A multifaceted physician education program using prototype materials from the Put Prevention Into Practice campaign with prevention lectures significantly increased the prevention knowledge and practices reported by physicians and the preventive services reported received by patients at an inner city municipal hospital.

Public preferences for prevention versus cure: what if an ounce of prevention is worth only an ounce of cure?

BACKGROUND: The belief that small preventive efforts bring large benefits may explain why many people say they value prevention above all other types of health care. However, it often takes a great deal of preventive medicine to prevent a bad outcome. This study explores whether people value prevention or cure more when each brings the same magnitude of benefit and examines whether preferences for prevention or cure vary according to the severity of the disability of the patients who can receive the preventive or curative intervention. METHODS: 289 prospective jurors were presented with a policy dilemma involving how best to allocate funds to benefit people with varying levels of disability. Each project was said to influence the functional ability of 100 nursing home residents, either by improving their level of function or by preventing their level of function from declining. RESULTS: When given a choice between preventive and curative interventions, more subjects preferred the preventive intervention (37% vs 21%, p=0.002). However, when the strength of people's preferences was taken into account, the preference for preventive interventions was not statistically significant (p=0.135). With both preventive and curative interventions, the subjects preferred helping patients with more severe disabilities (p < 0.005 for both comparisons). This preference for helping more severely disabled patients did not differ for prevention and cure (p=0.663). CONCLUSION: When the magnitude of benefit was held constant, the subjects slightly preferred prevention over cure. In addition, they preferred directing limited resources toward those with greater disabilities, regardless of whether those resources were targeted toward prevention or cure. These findings suggest that previously stated preferences for prevention over cure may result from a belief that small efforts at prevention will be repaid by large reductions in the later need for cure.

[Preventive pain therapy. Preventive tramadol infusion versus bolus application in the early postoperative phase].

Even today, adequate postoperative analgesia is still a great problem. Based on positive results of former studies using a continuous infusion of tramadol for postoperative pain relief, we aimed to improve this regimen. In order to investigate the effectiveness of preventive analgesia, one group of patients was given 100 mg tramadol (Tramal) at the time of extubation, followed by a maintenance infusion. The other group was treated with single boluses of tramadol on demand, thus representing common pain treatment. METHODS. 112 patients undergoing abdominal surgery were chosen at random for this double-blind study. Half of them (preventive group) received an injection of 100 mg tramadol at the time of extubation; the others (on-demand group) were given a placebo instead. A continuous infusion of 500 ml NaCl 0.9% (administered with 30 ml/h) followed, either containing 200 mg tramadol (preventive group) or a placebo (on-demand group) and was maintained until the end of the study. At the first expression of pain, patients in the preventive group received 50 mg tramadol (representing the first subsequent injection) whereas patients of the on-demand group were given 100 mg tramadol as a loading dose. For further treatment of pain, the members of both groups received 50 mg tramadol when necessary. The level of pain was assessed by means of VAS (visual analogue scale) every hour and additionally at first expression of pain, and finally by VRS (verbal rating scale) after eight hours at the end of the study. RESULTS. 112 patients were chosen at random. 18 had to be excluded--two treatment failures, twelve violations of the study protocol and four patients of the on-demand group, who did not ask for treatment for pain and therefore did not receive any tramadol. Hence only 94 patients could be statistically evaluated. 50% of the remaining 48 patients in the preventive group needed none or only one subsequent injection of tramadol, the other 50% needed two or more subsequent injections. However the patients in the on-demand group, now 46, split up into 71.7% who where administered up to one subsequent injection and 28.3% who received more than one subsequent injection. The number of patients who asked for treatment for pain twice or more during the study period totalled 50% in the preventive group and 58.7% in the on-demand group. The average interval between extubation and first expression of pain was 106.3 +/- 84.2 min in the preventive group, and 75.0 +/- 22.7 min in the on-demand group. The intensity of pain evaluated by VAS as that time was comparable: 55.6 +/- 22.7 (preventive) versus (63.4 +/- 18.3 (on demand). The pain relief obtained, shown by the VAS-differences between the first expression of pain and following assessment, came up to 27.7 +/- 22.9 in the preventive group and 30.3 +/- 23.4 in the on-demand group within a period of 46.2 +/- 17.2 min (preventive) and 43.7 +/- 17.2 min (on-demand). Retrograde assessment of pain (VRS) showed that 85.5% of the preventive group found pain relief excellent or good and 78.3% of the on-demand group were of the same opinion. Total consumption of tramadol totalled 281.4 +/- 53.6 mg in the preventive group in comparison with 150.0 +/- 53.7 mg in the on-demand group. CONCLUSIONS. Only 28.3% of patients of the on-demand group received more than one subsequent injection of tramadol in comparison with 50% of the preventive group--an unexpected result. However, it has to be considered that the injection of tramadol given at the first expression of pain in the preventive group was counted as the first subsequent injection already. The patients in the preventive group asked, on average, 30 min later for treatment for pain. The subsequent pain relief in both groups was comparable, although the amount of tramadol administered at that time was higher in the on demand group than in the preventive group (100 mg versus 50 mg+ amount given by infusion). These facts show the efficacy of the preventive infus

Prevention of oral mucositis or oral candidiasis for patients with cancer receiving chemotherapy (excluding head and neck cancer).

BACKGROUND: Treatment of cancer with chemotherapy is becoming increasingly more effective but is associated with short and long-term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. OBJECTIVES: To evaluate the effectiveness of oral (and topical) prophylactic agents for oral mucositis and oral candidiasis in patients with cancer (excluding head and neck cancer), compared with placebo or no treatment. SEARCH STRATEGY: Computerised MEDLINE, EMBASE, CINAHL, CANCERLIT, the Cochrane Controlled Trials Register and the Cochrane Oral Health Group Specialist Register search up to July 1999. Reference lists from relevant articles were scanned and the authors of eligible studies were contacted to identify trials and obtain additional information. SELECTION CRITERIA: Studies were selected if they met the following criteria: design - random or quasi-random allocation of participants; participants - anyone with cancer receiving chemotherapy (excluding head and neck cancer); interventions - prophylactic agents prescribed to reduce oral conditions arising from cancer or its treatment; outcomes - mucositis and oral candidiasis. DATA COLLECTION AND ANALYSIS: Information regarding methods, participants, interventions and outcome measures and results were independently extracted, in duplicate, by two reviewers (JC & HW). Specialist advice was sought to categorise interventions. Authors were contacted for details of randomisation and withdrawals and a quality assessment was carried out using the Jadad criteria (Jadad 1998). The Cochrane Oral Health Group statistical guidelines were followed and relative risk values calculated using random effects models where significant heterogeneity was detected (P < 0.1). MAIN RESULTS: Thirty-eight reports of trials were initially included. Two were duplicate reports and nine were excluded as there was no useable information. Of the 27 useable studies 14 had data for mucositis comprising 945 randomised patients and 15 included data for oral candidiasis with 1164 randomised patients. Of the eight prophylactic agents used for mucositis only one, ice chips, was effective (Relative risk 0.57, 95% CI 0.43 to 0.77, chi-square for heterogeneity = 0.26 (df = 1), p = 0.61). The NNT to prevent one extra case of mucositis over the baseline incidence using ice chips was 4 (95%CI: 3 to 7). The NNT for when the baseline incidence of mucositis in the population ranges from 50% to 80% are 5 to 4 respectively. There is evidence that antifungal agents which are partially or fully absorbed from the gastrointestinal tract prevent oral candidiasis and that the partially absorbed agents may be more effective than the fully absorbed agents. The RR for partially absorbed agents was 0.13 (95% CI 0.06 to 0.27, chi-square for heterogeneity = 5.3 (df = 3), P = 0. 15). The NNT to prevent one extra case of oral candidiasis over the baseline incidence using partially absorbed drugs was 3 (95% CI: 3 to 5). The NNT for when the baseline incidence of oral candidiasis in the population ranges from 30% to 70% are 4 to 2 respectively. The general reporting of RCT's was poor however the median Jadad score was acceptable and improved further when the authors provided additional information. The sensitivity analysis confirmed the findings for oral candidiasis. REVIEWER'S CONCLUSIONS: There is some evidence that ice chips prevent mucositis. None of the other prophylactic agents included in this review prevented mucositis. There is evidence that prophylactic use of antifungal agents which are absorbed or partially absorbed from the gastrointestinal tract reduce the clinical signs of oral candidiasis, and the partially absorbed drugs may be more effective. Future trials in this area should address the link between oral and general health including outcomes relevant to the patient. Collaboration between medical and dental teams is indicated.

Guideline for Prevention of Surgical Site Infection, 1999. Centers for Disease Control and Prevention (CDC) Hospital Infection Control Practices Advisory Committee.

EXECUTIVE SUMMARY The "Guideline for Prevention of Surgical Site Infection, 1999" presents the Centers for Disease Control and Prevention (CDC)'s recommendations for the prevention of surgical site infections (SSIs), formerly called surgical wound infections. This two-part guideline updates and replaces previous guidelines.1,2 Part I, "Surgical Site Infection: An Overview," describes the epidemiology, definitions, microbiology, pathogenesis, and surveillance of SSIs. Included is a detailed discussion of the pre-, intra-, and postoperative issues relevant to SSI genesis. Part II, "Recommendations for Prevention of Surgical Site Infection," represents the consensus of the Hospital Infection Control Practices Advisory Committee (HICPAC) regarding strategies for the prevention of SSIs.3 Whenever possible, the recommendations in Part II are based on data from well-designed scientific studies. However, there are a limited number of studies that clearly validate risk factors and prevention measures for SSI. By necessity, available studies have often been conducted in narrowly defined patient populations or for specific kinds of operations, making generalization of their findings to all specialties and types of operations potentially problematic. This is especially true regarding the implementation of SSI prevention measures. Finally, some of the infection control practices routinely used by surgical teams cannot be rigorously studied for ethical or logistical reasons (e.g., wearing vs not wearing gloves). Thus, some of the recommendations in Part II are based on a strong theoretical rationale and suggestive evidence in the absence of confirmatory scientific knowledge.It has been estimated that approximately 75% of all operations in the United States will be performed in "ambulatory," "same-day," or "outpatient" operating rooms by the turn of the century.4 In recommending various SSI prevention methods, this document makes no distinction between surgical care delivered in such settings and that provided in conventional inpatient operating rooms. This document is primarily intended for use by surgeons, operating room nurses, postoperative inpatient and clinic nurses, infection control professionals, anesthesiologists, healthcare epidemiologists, and other personnel directly responsible for the prevention of nosocomial infections. This document does not: Specifically address issues unique to burns, trauma, transplant procedures, or transmission of bloodborne pathogens from healthcare worker to patient, nor does it specifically address details of SSI prevention in pediatric surgical practice. It has been recently shown in a multicenter study of pediatric surgical patients that characteristics related to the operations are more important than those related to the physiologic status of the patients.5 In general, all SSI prevention measures effective in adult surgical care are indicated in pediatric surgical care. Specifically address procedures performed outside of the operating room (e.g., endoscopic procedures), nor does it provide guidance for infection prevention for invasive procedures such as cardiac catheterization or interventional radiology. Nonetheless, it is likely that many SSI prevention strategies also could be applied or adapted to reduce infectious complications associated with these procedures. Specifically recommend SSI prevention methods unique to minimally invasive operations (i.e., laparoscopic surgery). Available SSI surveillance data indicate that laparoscopic operations generally have a lower or comparable SSI risk when contrasted to open operations.6-11 SSI prevention measures applicable in open operations (e.g., open cholecystectomy) are indicated for their laparoscopic counterparts (e.g., laparoscopic cholecystectomy). Recommend specific antiseptic agents for patient preoperative skin preparations or for healthcare worker hand/forearm antisepsis.
