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.

Guidelines for the transfer of critically ill patients. Guidelines Committee, American College of Critical Care Medicine, Society of Critical Care Medicine and the 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 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. RESULTS OF 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 has allowed the authors to develop an evidence-based practice policy for the intra- and interhospital transport of the critically ill.

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.

Primary care research: barriers and opportunities.

A paucity of relevant scientific evidence limits the ability of the primary care disciplines to practice evidence-based medicine and to advocate for health care policy. Significant barriers to primary care research still exist, including difficulties in translating practice-based wisdom into methodologically sound research, the lack of a critical mass of researchers, a poorly developed research culture, and competing demands faced by investigators. In addition, the categorical nature of most available research funding is unfavorable for the generalist focus of primary care research. Efforts to advance primary care research will require support from health care organizations, dedicated federal and state funding sources, and foundations. In addition, there is a need to provide sophisticated methodological training for a small cadre of primary care researchers while increasing opportunities for a large number of clinicians to participate in research. Opportunities for transdisciplinary collaboration need to be increased, including the creation of primary care research centers. The development of a scientific basis for primary care practice will require policy advocacy, development of infrastructure, and creative and sustained individual effort.

Adherence to national guidelines for drug treatment of suspected acute myocardial infarction: evidence for undertreatment in women and the elderly.

BACKGROUND: Evidence-based guidelines for the treatment of patients with acute myocardial infarction (AMI) have been published and disseminated by the American College of Cardiology and the American Heart Association. Few studies have examined the rates of adherence to these guidelines in eligible populations and the influence of age and gender on highly effective AMI treatments in community hospital settings. METHODS: Medical records of 2409 individuals admitted to 37 Minnesota hospitals between October 1992 and July 1993 for AMI, suspected AMI, or rule-out AMI, and meeting electrocardiographic, laboratory, and clinical criteria suggestive of AMI were reviewed to determine the proportion of eligible patients who received thrombolytic, beta-blocker, aspirin, and lidocaine hydrochloride therapy. The effects of patient age, gender, and hospital teaching status on the use of these treatments were estimated using logistic regression models. RESULTS: Eligibility for treatment ranged from 68% (n=1627) for aspirin therapy, 38% (n=906) for lidocaine therapy, and 30% (n=734) for thrombolytic therapy to 19% (n=447) for beta-blocker therapy. Seventy-two percent of patients eligible to receive a thrombolytic agent received this therapy; 53% received beta-blockers; 81% received aspirin; and 88% received lidocaine. Among patients ineligible for lidocaine therapy (n=1503), 20% received this agent. Use of study drugs was lower among eligible elderly patients, especially those older than 74 years (thrombolytic agent: odds ratio, 0.2; 95% confidence interval, 0.1 to 0.4; aspirin: odds ratio, 0.4, 95% confidence interval, 0.3 to 0.6; beta-blocker: odds ratio, 0.4; 95% confidence interval, 0.2 to 0.8). Female gender was associated with lower levels of aspirin use among eligible patients (odds ratio, 0.7; 95% confidence interval, 0.6 to 0.9); and there was a trend toward lower levels of beta-blocker and thrombolytic use among eligible women. CONCLUSIONS: Use of lifesaving therapies for eligible patients with AMI is higher than previously reported, particularly for aspirin and thrombolytic use in nonelderly patients. Lidocaine is still used inappropriately in a substantial proportion of patients with AMI. Increased adherence to AMI treatment guidelines is required for elderly patients and women.

Preventive therapies: weighing the pros and cons.

The author comments on three issues raised by Dr. Kenneth G. Marshall in his series on the benefits and harms of preventive therapies, which begins in this issue on page 1493. First, because the method by which the results of clinical trials are presented markedly affects the perception of those results some measure of absolute benefit and harm must be used when the results of clinical trials are presented. Second, there is increasing interest in decision aids as a means of helping patients to understand evidence and make therapeutic choices. It is important that these aids undergo rigorous testing before they are adopted for common use. Third, evidence-based clinical practice guidelines are a welcome resource for busy clinicians. However, physicians and patients should bear in mind that interpretations of the available evidence can vary, leading to different conclusions about the appropriateness of preventive therapies.

Periodic health examination, 1996 update: 1. Prenatal screening for and diagnosis of Down syndrome. Canadian Task Force on the Periodic Health Examination.

OBJECTIVE: To make recommendations to physicians providing prenatal care on (1) whether prenatal screening for and diagnosis of Down syndrome (DS) is advisable and (2) alternative screening and diagnosis manoeuvres. OPTIONS: "Triple-marker" screening of maternal serum levels of alpha-fetoprotein, human chorionic gonadotropin and unconjugated estriol; fetal ultrasonographic examination; amniocentesis; and chorionic villus sampling (CVS). OUTCOMES: Accuracy of detection of DS in fetuses, and risks to the mother, including psychologic distress, and to the fetus from the screening and diagnostic interventions. EVIDENCE: A MEDLINE search for relevant articles published from Jan. 1, 1966, to Mar. 31, 1994, with the use of MeSH terms "Down syndrome," "prenatal diagnosis," "screening," "prevention," "amniocentesis," "chorionic villus sampling," "ultrasonography," "anxiety," "depression" and "psychological stress" and a manual search of bibliographies, recent issues of key journals and Current Contents. VALUES: The evidence-based methods and values of the Canadian Task Force on the Periodic Health Examination were used. A high value was placed on providing pregnant women with the opportunity to determine whether they are carrying a fetus with DS and to make choices concerning the termination of the pregnancy. The economic issues involved are complex and were not considered. BENEFITS, HARMS AND COSTS: Triple-marker screening identifies an estimated 58% of fetuses with DS, but it has an estimated rate of true-positive results of 0.1% and of false-positive results of 3.7% (given a risk cut-off of one chance in 190 of DS). These rates vary with maternal age and the risk cut-off chosen. Women with a known risk of having a fetus with DS (e.g., those who have had a previous child with DS) may benefit from a reduction in anxiety after confirmation that their fetus does not have DS. Screening allows women at low risk of having a child with DS to detect fetuses with the syndrome, but may cause psychologic distress if there is a false-positive screening test result. Up to 20% of women with positive results of screening tests may decline to undergo a subsequent amniocentesis. Amniocentesis and CVS are very accurate in diagnosing DS in fetuses and have a very low rate of serious complications for the mother. Amniocentesis is associated with a 1.7% rate of fetal loss when it is performed after 16 weeks' gestation, whereas the rate among controls is 0.7% (for a difference of 1%, 95% confidence interval 0.3% to 1.5%). CVS entails a greater risk of fetal loss than amniocentesis (odds ratio 1.32, 95% confidence interval 1.11 to 1.57). There is little evidence from controlled trials of significant associations between amniocentesis or CVS and neonatal morbidity or malformations; however, samples have been too small to show differences in rare outcomes. Results from some case-control studies suggest that CVS increases the risk of transverse limb deficiency. Costs were not considered because they are beyond the scope of this review. RECOMMENDATIONS: There is fair evidence to offer triple-marker screening through a comprehensive program to pregnant women under 35 years of age (grade B recommendation). Women given detailed information about serum-marker screening show more satisfaction with the screening than those not given this information. There is fair evidence to offer amniocentesis or CVS to pregnant women 35 years of age and older and to women with a history of a fetus with DS or of a chromosome 21 anomaly (grade B recommendation). Information on the limitations and advantages of each procedure should be offered. Triple-marker screening may be offered as an alternative to CVS or amniocentesis to pregnant women over 35. VALIDATION: Recommendations concerning prenatal diagnosis are similar to those of the US Preventive Services Task Force, the Society of Obstetricians and Gynaecologists of Canada, the Canadian College of Medical Geneticists and the Cochrane Pregnancy and Childbirth Group. No previous specific recommendations concerning triple-maker screening exist. SPONSORS: These guidelines were developed and endorsed by the Canadian Task Force on the Periodic Health Examination, which is funded by Health Canada and the National Health Research and Development Program.

Meta-analysis, clinical trials, and transferability of research results into practice. The case of cholesterol-lowering interventions in the secondary prevention of coronary heart disease.

OBJECTIVE: To evaluate, in the comprehensive scenario of "evidence-based" medicine, the transferability of the results of published randomized clinical trials and meta-analyses on cholesterol-lowering interventions to clinical practice. METHOD: Overview of randomized clinical trials on cholesterol-lowering interventions in the secondary prevention of coronary heart disease. RESULTS: The present overview on secondary prevention of coronary heart disease included 34 trials with cholesterol-lowering interventions in 24968 individuals. There was a 12.5% mortality in the group that was allocated active intervention and a 17.2% mortality in the control group (risk reduction, 13%; 95% confidence interval, -19% to -6%). Coronary and cardiovascular odds of deaths were significantly reduced. No clear association was found between noncoronary mortality and cholesterol-lowering interventions. Baseline total cholesterol levels had no clear influence on total mortality. Intermediate (10%-20%) and high ( > 20%) total cholesterol reductions were associated with similar reductions in the odds of death (-23% and -30%, respectively). No conclusion could be reached for patients who were less represented in the studies (ie, women and elderly persons). Patients with more complicated baseline clinical conditions (eg, congestive heart failure) had little nonsignificant benefit from cholesterol-lowering interventions. CONCLUSIONS: The effect of cholesterol-lowering interventions at least in the secondary prevention of coronary heart disease can be considered as established, but the transferability of such results to real-life patients remains the critical, unanswered question.

Periodic health examination, 1996 update: 2. Screening for chlamydial infections. Canadian Task Force on the Periodic Health Examination.

OBJECTIVE: To update the 1984 recommendations of the Canadian Task Force on the Periodic Health Examination on the routine screening of asymptomatic patients for infection with Chlamydia trachomatis. OPTIONS: Screening, with the use of culture or nonculture tests, of the general population, of certain high-risk groups or of all pregnant women; or no routine screening. OUTCOMES: Rates of asymptomatic and symptomatic chlamydial infection, perinatal complications, longterm complications of infection (i.e., pelvic inflammatory disease, infertility and ectopic pregnancy), coinfection with other sexually transmitted diseases, disease spread, hospital care, complications of therapy and costs of infection and of screening. EVIDENCE: Search of MEDLINE for articles published between Jan. 1, 1983, and Dec. 31, 1995, with the use of the major MeSH heading "chlamydial infections," references from recent review articles and recommendation by other organizations. VALUES: The evidence-based methods of the Canadian Task Force on the Periodic Health Examination were used. Advice from reviewers and experts and recommendations of other organizations were taken into consideration. Prevention of symptomatic disease and decreased overall costs were given high values. BENEFITS, HARMS AND COSTS: The greatest potential benefits of screening asymptomatic patients for chlamydial infections are the prevention of complications, especially infertility and perinatal complications, and the prevention of disease spread. There is no evidence that screening of the general population for chlamydial infections leads to a reduction in complications, and screening may increase costs. However, there is evidence that annual screening of selected high-risk groups and of pregnant women during the first trimester is beneficial in preventing symptoms and reducing the overall cost resulting from infection. RECOMMENDATIONS: There is fair evidence to support screening and treatment of pregnant women during the first trimester (grade B recommendation) as well as annual screening and treatment of high-risk groups (sexually active women less than 25 years of age, men or women with new or multiple sexual partners during the preceding year, women who use nonbarrier contraceptive methods and women who have symptoms of chlamydial infection: cervical friability, mucopurulent cervical discharge or intermenstrual bleeding; grade B recommendation). There is fair evidence to exclude routine screening of the general population (grade D recommendation). VALIDATION: These recommendations are similar to those of the US Preventive Services Task Force and the US Centers for Disease Control and Prevention, Atlanta. SPONSOR: These guidelines were developed and endorsed by the Canadian Task Force on the Periodic Health Examination, which is funded by Health Canada and the National Health Canada and the National Health Research and Development Program. The principal author (H.D.D.) was supported in part by the Ontario Ministry of Health and the Canadian Infectious Diseases Society Lilly Fellowship.

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.
