Background: Although supervision is a ubiquitous approach to support health programs and improve health care provider (HCP) performance in low- and middle-income countries (LMICs), quantitative evidence of its effects is unclear. The objectives of this study are to describe the effect of supervision strategies on HCP practices in LMICs and to identify attributes associated with greater effectiveness of routine supervision.Methods: We performed a secondary analysis of data on HCP practice outcomes (e.g., percentage of patients correctly treated) from a systematic review on improving HCP performance. The review included controlled trials and interrupted time series studies. We described distributions of effect sizes (defined as percentage-point [%-point] changes) for each supervision strategy. To identify attributes associated with supervision effectiveness, we performed random-effects linear regression modeling and examined studies that directly compared different approaches of routine supervision.Results: We analyzed data from 81 studies from 36 countries. For professional HCPs, such as nurses and physicians, primarily working at health facilities, routine supervision (median improvement when compared to controls: 10.7%-points; IQR: 9.9, 27.9) had similar effects on HCP practices as audit with feedback (median improvement: 10.1%-points; IQR: 6.2, 23.7). Two attributes were associated with greater mean effectiveness of routine supervision (p < 0.10): supervisors received supervision (by 8.8-11.5%-points), and supervisors participated in problem-solving with HCPs (by 14.2-20.8%-points). Training for supervisors and use of a checklist during supervision visits were not associated with effectiveness. The effects of supervision frequency (i.e., number of visits per year) and dose (i.e., the number of supervision visits during a study) were unclear. For lay HCPs, the effect of routine supervision was difficult to characterize because few studies existed, and effectiveness in those studies varied considerably. Evidence quality for all findings was low primarily because many studies had a high risk of bias.Conclusions: Although evidence is limited, to promote more effective supervision, our study supports supervising supervisors and having supervisors engage in problem-solving with HCPs. Supervision's integral role in health systems in LMICs justifies a more deliberate research agenda to identify how to deliver supervision to optimize its effect on HCP practices.

Background: Quality improvement collaboratives (QICs) have been used to improve health care for decades. Evidence on QIC effectiveness has been reported, but systematic reviews to date have little information from low- and middle-income countries (LMICs). Objective: To assess the effectiveness of QICs in LMICs. Methods: We conducted a systematic review following Cochrane methods, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for quality of evidence grading, and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement for reporting. We searched published and unpublished studies between 1969 and March 2019 from LMICs. We included papers that compared usual practice with QICs alone or combined with other interventions. Pairs of reviewers independently selected and assessed the risk of bias and extracted data of included studies. To estimate strategy effectiveness from a single study comparison, we used the median effect size (MES) in the comparison for outcomes in the same outcome group. The primary analysis evaluated each strategy group with a weighted median and interquartile range (IQR) of MES values. In secondary analyses, standard random-effects meta-analysis was used to estimate the weighted mean MES and 95% confidence interval (CI) of the mean MES of each strategy group. This review is registered with PROSPERO (International Prospective Register of Systematic Reviews): CRD42017078108. Results: Twenty-nine studies were included; most (21/29, 72.4%) were interrupted time series studies. Evidence quality was generally low to very low. Among studies involving health facility-based health care providers (HCPs), for “QIC only”, effectiveness varied widely across outcome groups and tended to have little effect for patient health outcomes (median MES less than 2 percentage points for percentage and continuous outcomes). For “QIC plus training”, effectiveness might be very high for patient health outcomes (for continuous outcomes, median MES 111.6 percentage points, range: 96.0 to 127.1) and HCP practice outcomes (median MES 52.4 to 63.4 percentage points for continuous and percentage outcomes, respectively). The only study of lay HCPs, which used “QIC plus training”, showed no effect on patient care-seeking behaviors (MES -0.9 percentage points), moderate effects on non-care-seeking patient behaviors (MES 18.7 percentage points), and very large effects on HCP practice outcomes (MES 50.4 percentage points). Conclusions: The effectiveness of QICs varied considerably in LMICs. QICs combined with other invention components, such as training, tended to be more effective than QICs alone. The low evidence quality and large effect sizes for QIC plus training justify additional high-quality studies assessing this approach in LMICs. [ABSTRACT FROM AUTHOR]

Background: Health care provider (HCP) performance in low- and middle-income countries (LMICs) is often inadequate. The Health Care Provider Performance Review (HCPPR) is a comprehensive systematic review of the effectiveness and cost of strategies to improve HCP performance in LMICs. We present the HCPPR’s methods, describe methodological and contextual attributes of included studies, and examine time trends of study attributes. Methods: The HCPPR includes studies from LMICs that quantitatively evaluated any strategy to improve HCP performance for any health condition, with no language restrictions. Eligible study designs were controlled trials and interrupted time series. In 2006, we searched 15 databases for published studies; in 2008 and 2010, we completed searches of 30 document inventories for unpublished studies. Data from eligible reports were double-abstracted and entered into a database, which is publicly available. The primary outcome measure was the strategy’s effect size. We assessed time trends with logistic, Poisson, and negative binomial regression modeling. We were unable to register with PROSPERO (International Prospective Register of Systematic Reviews) because the protocol was developed prior to the PROSPERO launch. Results: We screened 105,299 citations and included 824 reports from 499 studies of 161 intervention strategies. Most strategies had multiple components and were tested by only one study each. Studies were from 79 countries and had diverse methodologies, geographic settings, HCP types, work environments, and health conditions. Training, supervision, and patient and community supports were the most commonly evaluated strategy components. Only 33.6% of studies had a low or moderate risk of bias. From 1958–2003, the number of studies per year and study quality increased significantly over time, as did the proportion of studies from low-income countries. Only 36.3% of studies reported information on strategy cost or cost-effectiveness. Conclusions: Studies have reported on the efficacy of many strategies to improve HCP performance in LMICs. However, most studies have important methodological limitations. The HCPPR is a publicly accessible resource for decision-makers, researchers, and others interested in improving HCP performance.

Objectives. We evaluated an intervention to support health workers after training in Integrated Management of Childhood Illness (IMCI), a strategy that can improve outcomes for children in developing countries by encouraging workers' use of evidence-based guidelines for managing the leading causes of child mortality. Methods. We conducted a randomized trial in Benin. We administered a survey in 1999 to assess health care quality before IMCI training. Health workers then received training plus either study supports (job aids, nonfinancial incentives, and supervision of workers and supervisors) or usual supports. Follow-up surveys conducted in 2001 to 2004 assessed recommended treatment, recommended or adequate treatment, and an index of overall guideline adherence. Results. We analyzed 1244 consultations. Performance improved in both intervention and control groups, with no significant differences between groups. However, training proceeded slowly, and low-quality care from health workers without IMCI training diluted intervention effects. Per-protocol analyses revealed that workers with IMCI training plus study supports provided better care than did those with training plus usual supports (27.3 percentage-point difference for recommended treatment; P<.05), and both groups outperformed untrained workers. Conclusions. IMCI training was useful but insufficient. Relatively inexpensive supports can lead to additional improvements.

Background. In June 1998, we investigated one of the largest foodborne outbreaks of enterotoxigenic Escherichia coli gastroenteritis reported in the United States. Methods. We conducted cohort studies of 11 catered events to determine risk factors for illness. We used stool cultures, polymerase chain reaction, and serologic tests to determine the etiologic agent, and we conducted an environmental inspection to identify predisposing conditions and practices at the implicated establishment. Results. During 5-7 June, the implicated delicatessen catered 539 events attended by >16,000 people. Our epidemiological study of 11 events included a total of 612 attendees. By applying the median prevalence of illness (20%) among events with ill attendees to the total number of events with any ill attendees, we estimate that at least 3300 persons may have developed gastroenteritis during this outbreak. Multiple food items (potato salad, macaroni salad, egg salad, and watermelon) were associated with illness, all of which required extensive handling during preparation. Enterotoxigenic Escherichia coli serotype 06:H16 producing heat-labile and heat-stable toxins was isolated from the stool specimens from 11 patients. Eight patients with positive stool culture results, 11(58%) of 19 other symptomatic attendees, and 0 (0%) of 17 control subjects had elevated serum antibody titers to E. coli O6 lipopolysaccharide. The delicatessen had inadequate hand-washing supplies, inadequate protection against back siphonage of wastewater in the potable water system, a poorly draining kitchen sink, and improper food storage and transportation practices. Conclusions. In the United States, where enterotoxigenic Escherichia coli is an emerging cause of foodborne disease, enterotoxigenic Escherichia coli should be suspected in outbreaks of gastroenteritis when common bacterial or viral enteric pathogens are not identified.

Objectives. To characterize community health worker (CHW) performance using an algorithm for managing common childhood illnesses in Siaya District, Kenya, we conducted CHW evaluations in 1998, 1999, and 2001. Methods. Randomly selected CHWs were observed managing sick outpatient and inpatient children at a hospital, and their management was compared with that of an expert clinician who used the algorithm. Results. One hundred, 108, and 114 CHWs participated in the evaluations in 1998,1999, and 2001, respectively. The proportions of children treated "adequately" (with an antibiotic, antimalarial, oral rehydration solution, or referral, depending on the child's disease classifications) were 57.8%, 35.5%, and 38.9%, respectively, for children with a severe classification and 27.7%, 77.3%, and 74.3%, respectively, for children with a moderate (but not severe) classification. CHWs adequately treated 90.5% of malaria cases (the most commonly encountered classification). CHWs often made mistakes assessing symptoms, classifying illnesses, and prescribing correct doses of medications. Conclusions. Deficiencies were found in the management of sick children by CHWs, although care was not consistently poor. Key reasons for the deficiencies appear to be guideline complexity and inadequate clinical supervision; other possible causes are discussed.
