- Abstract
Since the 1990s, following similar reforms to its general politico-administrative systems, Uganda has decentralized its public healthcare system by shifting decision-making power away from its central Ministry of Health and towards more distal administrative levels. Previous research has used decision space-the decision-making autonomy demonstrated by entities in an administrative hierarchy-to measure overall health system decentralization. This study aimed to determine how the decision-making autonomy reported by managers of Ugandan healthcare facilities (de facto decision space) differs from that which they are allocated by official policies (de jure decision space). Additionally, it sought to determine associations between decision space and indicators of managerial performance. Using quantitative primary healthcare data from Ugandan healthcare facilities, our study determined the decision space expressed by facility managers and the performance of their facilities on measures of essential drug availability, quality improvement and performance management. We found managers reported greater facility-level autonomy than expected in disciplining staff compared with recruitment and promotion, suggesting that managerial functions that require less financial or logistical investment (i.e. discipline) may be more susceptible to differences in de jure and de facto decision space than those that necessitate greater investment (i.e. recruitment and promotion). Additionally, we found larger public health facilities expressed significantly greater facility-level autonomy in drug ordering compared with smaller facilities, which indicates ongoing changes in the Ugandan medical supply chain to a hybrid 'push-pull' system. Finally, we found increased decision space was significantly positively associated with some managerial performance indicators, such as essential drug availability, but not others, such as our performance management and quality improvement measures. We conclude that increasing managerial autonomy alone is not sufficient for improving overall health facility performance and that many factors, specific to individual managerial functions, mediate relationships between decision space and performance.

- Abstract
Background: Person-centeredness is a foundation of high-quality health systems but is poorly measured in low- and middle-income countries (LMICs). We piloted an online survey of four LMICs to identify the prevalence and correlates of excellent patient-reported quality of care (QOC).Objective: The aims of this study were to investigate the examine people's overall ratings of care quality in relation to their experiences seeking care in their respective health systems as well as individual-, provider- and facility-level predictors.Methods: We administered a cross-sectional online survey using Random Domain Intercept Technology to collect a sample of random internet users across India, Kenya, Mexico and Nigeria in November 2016. The primary outcome was patient-reported QOC. Covariates included age, gender, level of education, urban/rural residence, person for whom care was sought, type of provider seen, public or private sector status of the health facility and type of facility. The exposure was an index of health system responsiveness based on a framework from the World Health Organization. We used descriptive statistics to determine the prevalence of excellent patient-reported QOC and multivariable Poisson regression to calculate adjusted prevalence ratios (aPRs) for predictors of excellent patient-reported quality.Results: Fourteen thousand and eight people completed the survey (22.6% completion rate). Survey respondents tended to be young, male, well-educated and urban-dwelling, reflective of the demographic of the internet-using population. Four thousand one and ninety-one (29.9%) respondents sought care in the prior 6 months. Of those, 21.8% rated their QOC as excellent. The highest proportion of respondents gave the top rating for wait time (44.6%), while the lowest proportion gave the top rating for facility cleanliness (21.7%). In an adjusted analysis, people who experienced the highest level of health system responsiveness were significantly more likely to report excellent QOC compared to those who did not (aPR 8.61, 95% confidence interval [95% CI]: 7.50, 9.89). In the adjusted model, urban-dwelling individuals were less likely to report excellent quality compared to rural-dwelling individuals (aPR 0.88, 95% CI: 0.78, 0.99). People who saw community health workers (aPR 1.37, 95% CI: 1.12, 1.67) and specialists (aPR 1.30, 95% CI: 1.12, 1.50) were more likely to report excellent quality than those who saw primary care providers. High perceived respect from the provider or staff was most highly associated with excellent ratings of quality, while ratings of wait time corresponded the least.Conclusion: Patient-reported QOC is low in four LMICs, even among a well-educated, young population of internet users. Better health system responsiveness may be associated with better ratings of care quality. Improving person-centered care will be an important component of building high-quality health systems in these LMICs. [ABSTRACT FROM AUTHOR]- Published

Study Question: Is maternal polycystic ovarian syndrome (PCOS) associated with developmental delays in offspring?Summary Answer: Offspring of mothers with PCOS were at higher risk of failure on the Ages and Stages Questionnaire (ASQ).What Is Known Already: There is growing evidence that offspring of mothers with PCOS may be at higher risk for developmental disorders due to potential exposure to hyperandrogenism and insulin resistance. Few studies exist regarding maternal PCOS and early childhood development in the USA.Study Design, Size, Duration: The Upstate KIDS Study is a population-based prospective cohort study of infants born between 2008 and 2010 in New York State (excluding New York City), originally designed to study-and finding no impact of-infertility treatment exposure on child development. Children were followed up to 36 months of age. In all, 4453 mothers completed one or more developmental screening instruments for 5388 children (35.5% twins) up to 36 months of age.Participants/materials, Setting, Methods: In our study, 458 mothers (10.3%) reported a healthcare provider's diagnosis of PCOS, as well as the related treatment received, on the baseline study questionnaire. Parents completed the ASQ on their child's development at 4, 8, 12, 18, 24, 30 and 36 months of age to assess fine motor, gross motor, communication, personal-social functioning and problem-solving cognitive domains. We used generalized linear mixed models to estimate odds ratios (OR) between PCOS diagnosis and failures in the ASQ adjusted for maternal age, race, BMI, education, marital status, smoking, alcohol consumption, diabetes, insurance and plurality.Main Results and the Role Of Chance: Diagnosis of PCOS was associated with increased risk of the offspring failing the fine motor domain (adjusted odds ratio (aOR) = 1.77; 95% CI: 1.09, 2.89), largely driven by higher risk in female singletons (aOR = 2.23; 1.16, 4.29). Twins of mothers with PCOS had higher risk of failing the communication (aOR = 1.94; 1.19, 3.18) and personal-social functioning (aOR = 1.76; 1.12, 2.77) domains compared to twins born to mothers without PCOS. Compared to offspring of women without PCOS, offspring of women who reported receiving no treatment for their PCOS had a stronger association with failing the ASQ (aOR = 1.68; 0.95, 2.75) than the association among offspring of women who reported PCOS treatment (aOR = 1.16; 0.79, 1.73).Limitations, Reasons For Caution: Further study is needed to confirm the role of maternal PCOS in early offspring development with provider-validated diagnosis of PCOS.Wider Implications Of the Findings: If confirmed, these findings suggest that offspring of women with PCOS may be at increased risk for developmental delay.Study Funding/competing Interest(s): Supported by the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD; contracts HHSN275201200005C, #HHSN267200700019C).

Evidence from experimental studies suggests that the long-chain ω-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid have beneficial effects that may lead to reduced mortality from chronic diseases, but epidemiologic evidence is mixed. Our objective was to evaluate whether intake of long-chain ω-3 fatty acids from diet and supplements is associated with cause-specific and total mortality. Study participants (n = 70,495) were members of a cohort study (the Vitamins and Lifestyle Study) who were residents of Washington State aged 50–76 years at the start of the study (2000–2002). Participants were followed for mortality through 2006 (n = 3,051 deaths). Higher combined intake of eicosapentaenoic acid and docosahexaenoic acid from diet and supplements was associated with a decreased risk of total mortality (hazard ratio (HR) = 0.82, 95% confidence interval (CI): 0.73, 0.93) and mortality from cancer (HR = 0.77, 95% CI: 0.64, 0.92) but only a small reduction in risk of death from cardiovascular disease (HR = 0.87, 95% CI: 0.68, 1.10). These results suggest that intake of long-chain ω-3 fatty acids may reduce risk of total and cancer-specific mortality. [ABSTRACT FROM PUBLISHER]
