An approach to the development of practice guidelines for community health interventions.

The Community Health Practice Guidelines (CHPG) project was initiated to develop a systematic approach to the critical evaluation of evidence on the effectiveness and efficiency of community health interventions and to the formulation of evidence-based practice recommendations. Three community health interventions--immunization delivery methods, partner notification for sexually transmitted diseases and the combination of restaurant inspection and education of food handlers--were used as prototypes to develop a standardized approach. The CHPG process consists of three components: a review of scientific evidence, a practice survey and formulation of practice guidelines. Imperatives for further development of the CHPG and define research priorities process include creating a coalition of public health organizations to sponsor the process and refining the consensus process so that the practice guidelines accurately reflect both the scientific basis of public health practice and the values of those affected.

Development of sexually transmitted diseases treatment guidelines, 1993. New methods, recommendations, and research priorities. STD Treatment Guidelines Project Team and Consultants.

To develop the 1993 Sexually Transmitted Diseases Treatment Guidelines, experts from the Centers for Disease Control and Prevention reviewed the literature on sexually transmitted disease treatment, assembled tables of evidence, and listed key questions on therapeutic outcome: microbiologic cure, alleviation of symptoms, and prevention of sequelae and transmission. At a meeting with external experts, evidence was systematically assessed and guidelines developed. Quality of evidence for microbiologic cure was generally good for gonorrhea and chlamydia, poor for syphilis, and fair for most other diseases. Evidence on preventing sequelae and transmission was limited. The Guidelines include new recommendations for single-dose oral therapy of gonorrhea (cefixime, ciprofloxacin, and ofloxacin), chlamydia (azithromycin), and chancroid (azithromycin); outpatient therapy of pelvic inflammatory disease (ofloxacin and either clindamycin or metronidazole); and patient-applied therapy of genital warts (podofilox). Syphilis therapy did not change substantially. Several global issues that emerged during the development of the World Health Organization Recommendations for the Management of Sexually Transmitted Diseases also are discussed. This evidence-based approach clarified important treatment issues and the rationale for recommendations, and identified research priorities.

An overview of clinical policies with implications for clinical practice, medical education, and research.

Clinical policies, also known as practice parameters or practice guidelines, are gaining notoriety out of a desire to control escalating medical costs, lessen wide practice variations, and improve quality of care. The clinical policies are supposed to influence medical decision making by summarizing scientific data about a clinical problem in a format that is easily understood by patient and physician alike. Developing an evidence-based policy involves: a clearly defined clinical problem, a comprehensive literature review, a summary table of the data (known as an evidence table), a presentation of this data as outcome possibilities from alternative decisions (in the form of a balance sheet), and creation of clinical recommendations that incorporate both financial costs and patient preferences. Well-developed policies can be used by family physicians as guides in areas of clinical uncertainty and by medical educators as up-to-date literature syntheses for teaching critical appraisal and for outlining approaches to common problems. Explicit policy formulation also highlights the shortcomings of existing literature and can suggest more appropriate future research. The future of the clinical policy movement rests on its ability to reduce costs of care and improve patient outcomes. Explicit clinical policy formulation incurs significant development and implementation costs and the evidence on which many policies are based is lacking. Nevertheless, clinical policies in some form are likely to play an increasing role in medical care.

Guidelines for the transfer of critically ill patients. Guidelines Committee of the American College of Critical Care Medicine; Society of Critical Care Medicine and American Association of Critical-Care Nurses Transfer Guidelines Task Force.

OBJECTIVE: The development of practice guidelines for the conduct of intra- and interhospital transport of the critically ill patient. DATA SOURCES: A task force of experts in the field of patient transport drawn from the membership of the Society of Critical Care Medicine and the American Association of Critical-Care Nurses provided the personal experience and published literature from which these guidelines were developed. STUDY SELECTION: Study design was not a factor in selecting the literature to validate the experts' personal experience. The lack of well-designed clinical outcome studies was an important factor in determining the method of practice policy development we utilized. DATA EXTRACTION: The expert task force met and developed a draft of these guidelines based on their experiences and the available literature. This draft document was then reviewed by an additional group of experts whose input was used by the task force to develop this final consensus report. DATA SYNTHESIS: Each hospital should have a formalized plan for intra- and interhospital transport that addresses the following elements: pretransport coordination and communication, transport equipment, accompanying personnel, monitoring during the transport, and documentation. The transport plan should be developed by a multidisciplinary team and should be evaluated and refined by the continuous quality improvement process. CONCLUSION: The available data have allowed us to develop an evidence-based practice policy for the intra- and interhospital transport of the critically ill.

Periodic health examination, 1994 update: 1. Obesity in childhood. Canadian Task Force on the Periodic Health Examination.

OBJECTIVE: To update the 1979 Canadian Task Force on the Periodic Health Examination recommendation on screening for childhood obesity by reviewing any new evidence concerning health risks in childhood and adulthood, and effective preventive or therapeutic interventions. OPTIONS: Detection: routine measurement of height and weight, use of skinfold thickness measurements, calculation of body mass index (BMI). INTERVENTION: diet, exercise, behaviour modification and comprehensive family-based weight-reduction programs. Components of these interventions could be offered routinely or reserved for children and families who perceive obesity to be a present or potential problem. OUTCOMES: The task force reviewed the probability of obese children become obese adults as a risk factor for adult heart disease and overall related illness and death in adult life as well as obesity as a risk factor for physical and psychologic illness in childhood. EVIDENCE: A MEDLINE search for relevant articles published between January 1981 and February 1991 was undertaken. VALUES: The task force's evidence-based rules for recommendations were used. BENEFITS, HARMS AND COSTS: If weight reduction in childhood were shown to prevent physical or psychologic illness in childhood, or illness and death in adult life, screening and treatment should be recommended. Screening for obesity may cause anxiety on the part of the child and family; malnutrition in children as a result of parents becoming overly anxious about the health risks of obesity has been reported. Most weight reduction programs have limited long-term effectiveness and can be costly. RECOMMENDATIONS: There is insufficient evidence of short-term or long-term benefits from screening for or treatment of childhood obesity to recommend such screening or recommend against it. There is fair evidence to recommend against very-low-kilojoule diets for preadolescents. There is insufficient evidence to recommend for or against exercise programs or intensive family-based programs for most obese children. VALIDATION: These recommendations are similar to those of the American Academy of Pediatrics and the US Preventive Services Task Force. SPONSOR: These guidelines were developed and endorsed by the Canadian task force, which is funded by Health Canada.

Sickle cell disease: screening, diagnosis, management, and counseling in newborns and infants. The Agency for Health Care Policy and Research.

The AHCPR guideline on sickle cell disease has several strengths and many weaknesses. For the practicing physician it is strongest in recommending medical management of infants with sickle cell disease but weakest on screening and education and counseling. The evidence-based methodology should have been presented in more detail. Until that occurs, family physicians are left with this guideline as a summary of expert opinions with variable documentation of the underlying science.

Periodic health examination, 1993 update: 3. Periodontal diseases: classification, diagnosis, risk factors and prevention. Canadian Task Force on the Periodic Health Examination.

OBJECTIVE: To review the 1979 Canadian Task Force on the Periodic Health Examination recommendations on the diagnosis and prevention of periodontal disease. OPTIONS: Self-care at home, professional care, treatment with antimicrobial agents and management of patients at high risk. OUTCOMES: Maintaining the gingiva, alveolar bone and periodontal ligament in a healthy state (absence of gingival bleeding and no loss of epithelial attachment). EVIDENCE: A literature search for articles published from 1980 to 1993 was conducted. Selected studies published before 1980 were also reviewed if there were no recent updates. Evidence was evaluated and classified as good, fair or poor according to the criteria of the task force. VALUES: The task force's evidence-based rules for recommendations were used. In addition, whenever feasible, and on the basis of advice from the reviewers and experts, recommendations were modified in the interest of maintaining oral health (e.g., dental flossing in children). BENEFITS, HARMS AND COSTS: The recommendations are not expected to increase the costs of preventing periodontal diseases for the general population. They could benefit dental patients and reduce costs because they are based on the periodontal needs of patients rather than on the current universal application approach.

Report of the Canadian Hypertension Society Consensus Conference: 4. Hypertension in the elderly.

Several knowledge gaps, which made evidence-based guidelines impossible in 1985, have since been filled. There is now unequivocal evidence that treatment of isolated systolic hypertension benefits elderly patients, as does treatment beyond the age of 75 years. Pseudohypertension, although occasionally problematic, is not common and is not a reason to neglect the treatment of elderly patients, including those with isolated systolic hypertension. In general, long-term antihypertensive treatment of the elderly is well tolerated and does not cause important decreases in mental function. Comparative drug studies continue to accumulate; most show no clinically significant general differences between drugs, aside from the somewhat decreased efficacy and tolerability of beta-blockade in elderly patients. As in the young, certain drugs may be preferred in the presence of other conditions--e.g., congestive heart failure or diabetes.

Whither ultrasonic prediction of fetal macrosomia?

During the past 15-20 years, ultrasonic estimation of fetal weight (EFW) has been used increasingly to make management decisions regarding the induction of labor or delivery route. The propriety of this approach depends on proof that its use improves newborn or maternal outcome without disproportionate increases in morbidity and mortality. A barrier to achieving this goal is the inaccuracy associated with ultrasonic EFW. The current ultrasonic EFW procedures are not accurate enough for detecting macrosomia defined by weight criteria. Even if clinicians could determine fetal weight accurately, the frequency of persistent fetal injuries associated with vaginal birth of the macrosomic fetus is so low that induction of labor or cesarean birth is not justified on that basis. Furthermore, the inaccurate ultrasonic determination of fetal weight leads to inappropriate obstetric interventions. Evidence-based decision-making should be an important goal for all obstetric care givers. Delivery decisions based on inaccurate EFW should be avoided.

A model for technology assessment applied to pulse oximetry. The Technology Assessment Task Force of the Society of Critical Care Medicine.

OBJECTIVES: To test a model for the assessment of critical care technology. To develop practice guidelines for the use of pulse oximetry. DATA SOURCES: A computer-assisted search of the English language literature and interviews with recognized experts in the field of pulse oximetry. STUDY SELECTION: Those studies that addressed one or more of the seven questions contained in our technology assessment template were analyzed. Study design was not a factor in article selection. However, the lack of well-designed clinical outcome studies was an important factor in determining the method of practice policy development we utilized. DATA EXTRACTION: A focus person summarized the data from the selected studies that related to each of the seven assessment questions. The preliminary data summary developed by the focus person was further analyzed and refined by the task force and then sent to 16 expert reviewers for comment. These expert comments were considered by the task force, and this final consensus report was developed. DATA SYNTHESIS: Pulse oximetry combines the principles of spectrophotometry and plethysmography to noninvasively measure oxygen saturation with a high degree of accuracy over the range of 80% to 100% saturation, assuming the device is being used according to the manufacturer's instructions and without any adverse operating conditions. The appropriate clinical uses of pulse oximetry fall into one of two broad categories: as a warning system based on continuous real-time measurement of arterial desaturation, or as an end-point for titration of therapeutic interventions. There are no published studies that allow for definitive, outcome-based conclusions concerning either the clinical impact or cost-benefit ratio of pulse oximetry. CONCLUSIONS: The model developed for technology assessment proved to be appropriate for assessing pulse oximetry. The available data have allowed us to develop an evidence-based practice policy for the use of pulse oximetry in critical care. Critical care clinicians, researchers, and industry have a shared responsibility to provide valid outcome and efficacy studies of new technologies.

Dissemination of guidelines on cholesterol. Effect on patterns of practice of general practitioners and family physicians in Ontario. Ontario Task Force on the Use and Provision of Medical Services.

A telephone survey of a random sample of Ontario family physicians was conducted 6 to 8 months after disseminating evidence-based guidelines for screening and managing asymptomatic hypercholesterolemia. Seventy-eight percent of respondents stated they followed these guidelines. However, specific questions revealed as few as 5% of respondents actually followed the guidelines.

Patients with urinary tract infection: proposed management strategies of general practitioners, microbiologists and urologists.

BACKGROUND: It is difficult to implement change in general practice. It is not known how best to conduct effective continuing medical education in general practice. General practitioners' criteria for good clinical practice vary and it is unknown whether systematic education by hospital specialists could be expected to reduce variation between general practitioners. AIM: A study was undertaken to describe general practitioners', microbiologists' and urologists' strategies for diagnosis, treatment, and follow up of female patients with symptoms of urinary tract infection, a common reason for consultation in general practice. The findings of the study were to be used as a base upon which to discuss the advantages and disadvantages of using hospital specialists as a resource in general practitioners' peer group based continuing medical education. METHOD: Three vignettes together with several proposals for diagnosis, treatment and follow up were presented in a questionnaire to general practitioners, microbiologists and urologists in Denmark. The case histories concerned three female patients (aged 10, 30 and 60 years) who consulted their general practitioner for advice. The female patients were otherwise healthy and well known to the practice. General practitioners', microbiologists' and urologists' recommendations for good clinical practice were compared. RESULTS: A total of 154 general practitioners (77%), 45 microbiologists (51%) and 54 urologists (61%) who were eligible for the study responded to the questionnaire. There was considerable variation in the management strategies proposed by doctors within each specialty and between the specialties. Microbiologists and urologists were more likely to suggest treating the 30-year-old woman by giving advice and a prescription by telephone compared with their general practitioner colleagues. Conversely, the microbiologists and urologists were more likely to suggest asking the 10- and 60-year-old patients to attend the clinic for examination compared with the general practitioners. The general practitioners reported asking the patients to return for follow up more commonly than the hospital specialists. CONCLUSION: Large variation in suggested strategies for diagnosis, treatment and follow up was shown both within and between specialties. Continuing medical education of general practitioners based on small peer group discussions using hospital specialists as a group resource would not necessarily reduce variation in clinical practice between general practitioners. A need for evidence-based rather than consensus-directed guidelines would be needed in order to reduce variation in clinical practice between doctors.

What's the meta now? More updates on the problems with systematic reviews.

BACKGROUND: Systematic reviews are intended to provide trustworthy evidence synthesis, yet previous iterations of this living review have identified numerous recurring problems in their conduct and reporting. This article presents the third version and second update of the living systematic review examining issues raised across the academic literature. METHODS: Using consistent eligibility criteria and methods from earlier versions, literature searches were updated to May 2025. Eligible meta-research and editorial articles describing problems with systematic reviews were analyzed to identify emerging themes. Additionally, four basic indicators of methodological quality of the included meta-research were presented across review versions. RESULTS: The update included 209 additional articles. Critically low methodological quality and absence of protocols remained among the most frequently reported issues in systematic reviews across disciplines and journals but notably in evidence underpinning clinical practice guidelines. Spin in abstracts and conflicts of interest continued to be common. Apparent improvements in reporting quality were inconsistent, with modest gains in some full-text reporting but persistent deficiencies in abstracts. Authorship diversity of systematic reviews improved in gender representation but remained geographically concentrated in high-income countries, and primary research included in reviews similarly lacked global representativeness. The issue of misalignment between systematic review evidence bases and global burden of disease bring the total number of problems with systematic reviews to 69. Emerging use of automation and artificial intelligence was variably reported. Descriptive comparison of meta-research articles over the three versions of this living review suggests a greater proportion meeting basic quality indicators in more recent updates. CONCLUSION: Across successive updates, problems with systematic reviews remain widespread and consistent rather than isolated. Incremental reporting improvements coexist with persistent concerns about transparency, bias, and representativeness. Future efforts should prioritize evaluating interventions and aligning research incentives to support genuinely trustworthy evidence synthesis.

Interventions with a significant mortality difference in acute respiratory distress syndrome: A systematic review and comparison with Guidelines.

INTRODUCTION: Acute respiratory distress syndrome (ARDS) has a high mortality rate. European Society of Intensive Care Medicine (ESICM) and American Thoracic Society (ATS) Guidelines are the worldwide reference for clinicians in management of ARDS. Mortality represents one of the most important outcomes in intensive care practice and randomized controlled trials (RCTs) the highest level of evidence. We compared Guidelines recommendations with RCT results to highlight differences and find potential new therapeutic opportunities. METHODS: We performed a systematic review of all RCTs reporting a statistically significant mortality difference in ARDS and a subsequent comparison with ESICM and ATS Guidelines recommendations. RESULTS: We identified 33 RCTs and 23 interventions with mortality difference in ARDS patients. Seven interventions relate to invasive ventilation strategies, two to noninvasive ventilation strategies, one to extracorporeal membrane oxygenation (ECMO), 12 to drugs and one to nutritional support. In 25/33 (76%) RCTs the intervention was associated with mortality reduction and in 8/33 with mortality increase (24%). Multicenter studies were 24/33 (73%) while blinding was adopted in 19/33 (58%) studies. Guidelines recommendations supported by RCTs with mortality impact include: the use of low tidal volume ventilation, prone positioning, venovenous ECMO, steroids and the avoidance of high frequency oscillatory ventilation. Eight of the interventions identified were not mentioned by Guidelines but demonstrated reduced mortality, and five further interventions demonstrated increased mortality. CONCLUSIONS: This systematic review highlights potential gaps between RCTs results and Guidelines that could be used to plan future research or highlight topics to be discussed in future Guidelines.

Assessment of blinding in pharmacotherapy and noninvasive neuromodulation randomized controlled trials for neuropathic pain in adults.

In randomized controlled trials (RCTs), study participants and research personnel are often blinded to minimize biases related to knowing treatment allocation. To determine if blinding was effective, participants may be asked which treatment they believe they received ("treatment guess"). This descriptive review characterized blinding assessment (BA) reporting in pharmacotherapy and neuromodulation neuropathic pain RCTs. Of 288 papers, 36 (12.5%) reported a BA. One paper reported the results of 2 studies, so in total 37 studies with a BA were assessed. Of these, 19 were crossover, 17 parallel, and 1 partial crossover in design. All 37 studies assessed participant blinding, and 10 also assessed investigator blinding. Approximately 27% included an "unsure" answer option for treatment guess, and 38% asked the reason for the guess. There were no clear patterns in BA reporting across time nor based on treatment type. Seventeen trials provided sufficient data to calculate Bang Blinding Index (BI) to determine blinding success. Participants remained blinded (BI = 0 &#xb1; 0.2) in 10/17 placebo and 10/17 treatment arms, 6 placebo and 5 treatment arms had a BI > 0.2 suggesting possible unblinding, whereas 1 placebo and 2 treatment arms had a BI < -0.2 suggesting misinformed guessing. Overall, we found that BAs are done in a minority of published neuropathic pain trials and with variable methodology. Given the importance of minimizing risk of bias because of treatment unblinding, future studies should consider including BAs, and further consensus building is necessary to determine if and how BAs should be conducted and interpreted in analgesic clinical trials.

Impact of Physical Environment of Pediatric Inpatient Wards on Children: A Systematic Literature Review.

ObjectiveThe study aimed to examine empirical studies published between 2003 and 2025 to identify elements of physical environments influencing health outcomes and experiences of children and families.BackgroundIn the past 40 years, research has shown that the physical environment influences the health and well-being of patients in the healthcare environment. However, similar research in the context of "pediatric inpatient wards" remains underexplored.MethodsPubMed, Embase, Scopus, and Web of Science were used to identify relevant articles. All extracted articles underwent a three-step screening process using PRISMA. A total of 30 eligible articles were used for the analysis. The protocol is registered at PROSPERO (CRD42023408997).ResultsKey findings reveal positive and negative impacts of identified elements. Positive-effect elements include play spaces, space for parents, natural light, connections with nature, and so on, which promote comfort, healing, and emotional resilience. Conversely, negative-effect elements, such as noise, artificial lighting, uncomfortable temperature, and so on, contribute to stress and disrupted sleep. Mixed effects were observed for elements like art and television, which underscore the complexity of designing environments that address the diverse needs of different age groups and genders.ConclusionsThe review findings highlight significant knowledge gaps. The study also tries to bridge existing gaps between research and practice by systematically identifying environmental elements, offering actionable insights to architects, designers, healthcare providers, and policymakers. Future research must adopt rigorous, culturally inclusive approaches to advance the field of pediatric healthcare design and ensure equitable care across diverse sociocultural contexts.

A Digital Tool for Clinical Evidence-Driven Guideline Development by Studying Properties of Trial Eligible and Ineligible Populations: Development and Usability Study.

BACKGROUND: Clinical guideline development preferentially relies on evidence from randomized controlled trials (RCTs). RCTs are gold-standard methods to evaluate the efficacy of treatments with the highest internal validity but limited external validity, in the sense that their findings may not always be applicable to or generalizable to clinical populations or population characteristics. The external validity of RCTs for the clinical population is constrained by the lack of tailored epidemiological data analysis designed for this purpose due to data governance, consistency of disease or condition definitions, and reduplicated effort in analysis code. OBJECTIVE: This study aims to develop a digital tool that characterizes the overall population and differences between clinical trial eligible and ineligible populations from the clinical populations of a disease or condition regarding demography (eg, age, gender, ethnicity), comorbidity, coprescription, hospitalization, and mortality. Currently, the process is complex, onerous, and time-consuming, whereas a real-time tool may be used to rapidly inform a guideline developer's judgment about the applicability of evidence. METHODS: The National Institute for Health and Care Excellence-particularly the gout guideline development group-and the Scottish Intercollegiate Guidelines Network guideline developers were consulted to gather their requirements and evidential data needs when developing guidelines. An R Shiny (R Foundation for Statistical Computing) tool was designed and developed using electronic primary health care data linked with hospitalization and mortality data built upon an optimized data architecture. Disclosure control mechanisms were built into the tool to ensure data confidentiality. The tool was deployed within a Trusted Research Environment, allowing only trusted preapproved researchers to conduct analysis. RESULTS: The tool supports 128 chronic health conditions as index conditions and 161 conditions as comorbidities (33 in addition to the 128 index conditions). It enables 2 types of analyses via the graphic interface: overall population and stratified by user-defined eligibility criteria. The analyses produce an overview of statistical tables (eg, age, gender) of the index condition population and, within the overview groupings, produce details on, for example, electronic frailty index, comorbidities, and coprescriptions. The disclosure control mechanism is integral to the tool, limiting tabular counts to meet local governance needs. An exemplary result for gout as an index condition is presented to demonstrate the tool's functionality. Guideline developers from the National Institute for Health and Care Excellence and the Scottish Intercollegiate Guidelines Network provided positive feedback on the tool. CONCLUSIONS: The tool is a proof-of-concept, and the user feedback has demonstrated that this is a step toward computer-interpretable guideline development. Using the digital tool can potentially improve evidence-driven guideline development through the availability of real-world data in real time.
