In this paper, we argue that understanding and addressing the problem of poor-quality medical products requires a more interdisciplinary approach than has been evident to date. While prospective studies based on rigorous standardized methodologies are the gold standard for measuring the prevalence of poor-quality medical products and understanding their distribution nationally and internationally, they should be complemented by social science research to unpack the complex set of social, economic, and governance factors that underlie these patterns. In the following sections, we discuss specific examples of prospective quality surveys and of social science studies, highlighting the value of cross-sector partnerships in driving high-quality, policy-relevant research in this area. 相似文献

ObjectivesTo determine the prevalence of restless legs syndrome (RLS) and RLS-mimic conditions, the risk factors for RLS, and whether RLS contributes to functional impairment in children and adolescents with attention-deficit/hyperactivity disorder (ADHD).MethodsADHD children and adolescents were prospectively studied at the outpatient psychiatric clinic. A trained registered nurse used the 2012 Revised International Restless Legs Syndrome Study Group diagnostic criteria to diagnose RLS. Sociodemographic data and medical records were reviewed. Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) Thai version was used to identify association between RLS and 6 domains of function [family, school (learning), school (behavior), life skills, child self-concept, social activities, and risky activities].ResultsA total of 217 patients were included. Of those, 23 (11%) patients met the criteria for RLS, and 49 (23%) had RLS-mimic conditions. Those conditions included myalgia (30/49), habitual foot tapping (23/49), positional discomfort (20/49), leg ulcer/bruise (1/49), and arthralgia/arthritis (1/49). Binary logistic regression revealed first-degree relative having RLS symptom to be significantly associated with RLS in study patients (OR: 5.06, p < 0.01). Multivariate linear regression showed RLS to be independently associated with school (behavior) (Β = 1.18, p = 0.05) and life skills (Β = 2.36, p = 0.05) impairment.ConclusionsRLS was found to be common in ADHD children and adolescents. RLS-mimic conditions were found in two-thirds of patients who previously met 4 essential RLS criteria. First-degree relative with RLS symptom was associated with RLS, and RLS was associated with functional impairment in the life skills and school (behavior) domains. 相似文献

ObjectivesThis study primarily aimed to explore injury incidence rates in the three main domestic competition formats in England and Wales (First-Class, One-Day and Twenty20 [T20]). For the first time, the study also describes the epidemiology of elite men’s domestic cricket injuries across nine seasons (2010–2018 inclusive).DesignProspective cohort analysis.MethodsInjury incidence and prevalence from all injuries calculated according to the updated international consensus statement on injury surveillance in cricket, with statistical process control charts (SPC) used to detect trends in the data.ResultsThe average match injury incidence was 102 injuries/1000 days of play, with highest incidence in One-Day (254 injuries/1000 days of play), followed by T20 (136 injuries/1000 days of play) and First-Class Cricket (68 injuries/1000 days of play). Most match injuries were sustained during bowling (41.6 injuries/1000 days of play), followed by fielding (26.8 injuries/1000 days of play) and batting (22.3 injuries/1000 days of play). The thigh was the body area most commonly injured (7.4 injuries/100 players per season), with lumbar spine injuries the most prevalent (1.3% of players unavailable on any given day during the season). On average, 7.5% of players were unavailable on any given day during the domestic season when all injuries were considered (match and training). The SPC charts showed relatively consistent match injury incidence for all competitions, reproduced across all nine seasons.ConclusionThese findings provide a robust empirical base for the extent of the injury problem in domestic cricket played in England and Wales, with similar injury profiles across the three formats. 相似文献

目的 探讨台州市功能性消化不良的流行病学现状及影响因素。方法 回顾性选取2020年1月至2022年2月浙江省台州医院收治的功能性消化不良患者200例,统计患者的一般资料,分析该病的流行病学现状,对功能性消化不良的影响因素进行单因素分析,然后将差异有统计学意义的因素再进一步纳入多因素Logistic回归分析。结果 200例功能性消化不良患者中,女性发病率高于男性;30~60岁年龄段群体,患病率最高;存在暴饮暴食、喜食烫食、挑食、多食酸制品、未准时进食、常食宵夜、睡眠时间<6h、有药物过敏史、有功能性消化不良家族史、存在便秘情况者的患病率均高于未存在以上情况者,差异均有统计学意义(P<0.05)。多因素Logistic回归分析显示,性别、年龄、暴饮暴食、喜食烫食、挑食、多食酸制品、未准时进食、宵夜摄取情况、每天睡眠时间、药物过敏史、家族史、便秘是该病患病率升高的主要影响因素。结论 性别、年龄、暴饮暴食、喜食烫食、挑食、酸制品、未准时进食情况、宵夜摄取情况、每天睡眠时间、药物过敏史、家族史、便秘是功能性消化不良的主要影响因素。 相似文献
