RESUMO
Objective: The objective was to describe the relationship between the location of care, the malaria test result, and the type of medicine consumed for the fever, and to determine whether community-based access to malaria testing reduced polypharmacy. Methods: This is a secondary analysis of a cluster-randomized trial of an intervention designed to increase diagnostic testing and targeting of Artemesinin Combined Therapies (ACTs). Data collected at baseline, 12, and 18 months were analyzed to determine the impact of diagnostic testing on drug consumption patterns among febrile individuals. Results: Of the 5,756 participants analyzed, 60.1% were female, 42% were aged 5-17 years, and 58.1% sought care for fever in a retail outlet. Consumption of both ACT and antibiotics was 22.1% (n = 443/2008) at baseline. At endline, dual consumption had declined to 16.6%. There was reduced antibiotic consumption among those testing positive for malaria (39.5%-26.5%) and those testing negative (63.4%-55.1%), accompanied by a substantial decline in ACT use among malaria-negative participants. Conclusion: Diagnostic testing for malaria reduces dual consumption of ACTs and antibiotics, especially among those testing outside the formal healthcare sector.

Overstating the impact of interventions through incomplete or inaccurate reporting can lead to inappropriate scale-up of interventions with low impact. Accurate reporting of the impact of interventions is of great importance in global health research to protect scarce resources. In global health, the cluster randomised trial design is commonly used to evaluate complex, multicomponent interventions, and outcomes are often binary. Complete reporting of impact for binary outcomes means reporting both relative and absolute measures. We did a systematic review to assess reporting practices and potential to overstate impact in contemporary cluster randomised trials with binary primary outcome. We included all reports registered in the Cochrane Central Register of Controlled Trials of two-arm parallel cluster randomised trials with at least one binary primary outcome that were published in 2017. Of 73 cluster randomised trials, most (60 [82%]) showed incomplete reporting. Of 64 cluster randomised trials for which it was possible to evaluate, most (40 [63%]) reported results in such a way that impact could be overstated. Care is needed to report complete evidence of impact for the many interventions evaluated using the cluster randomised trial design worldwide.

Background: India's high prevalence of iron-deficiency anemia has largely been attributed to the local diet consisting of nonheme iron, which has lower absorption than that of heme iron.Objective: We assessed the efficacy of the consumption of iron-supplement bars in raising hemoglobin concentrations and hematocrit percentages in anemic (hemoglobin concentration <12 g/dL) Indian women of reproductive age.Design: The Let's be Well Red study was a 90-d, pair-matched, cluster-randomized controlled trial. A total of 361 nonpregnant women (age 18-35 y) were recruited from 10 sites within Mumbai and Navi Mumbai, India. All participants received anemia education and a complete blood count (CBC). Random assignment of anemic participants to intervention and control arms occurred within 5 matched site-pairs. Intervention participants received 1 iron-supplement bar (containing 14 mg Fe)/d for 90 d, whereas control subjects received nothing. CBC tests were given at days 15, 45, and 90. Primary outcomes were 90-d changes from baseline in hemoglobin concentrations and hematocrit percentages. Linear mixed models and generalized estimating equations were used to model continuous and binary outcomes, respectively.Results: Of 179 anemic participants, 136 (76.0%) completed all follow-up assessments (65 intervention and 71 control participants). Baseline characteristics were comparable by arm. Mean hemoglobin and hematocrit increases after 90 d were greater for intervention than for control participants [1.4 g/dL (95% CI: 1.3, 1.6 g/dL) and 2.7% (95% CI: 2.2%, 3.2%), respectively]. The anemia prevalence at 90 d was lower for intervention (29.2%) than for control participants (98.6%) (OR: 0.007; 95% CI: 0.001, 0.04).Conclusions: The daily consumption of an iron-supplement bar leads to increased hemoglobin concentrations and hematocrit percentages and to a lower anemia prevalence in the target population with no reported side effects. This intervention is an attractive option to combat anemia in India. This trial was registered at clinicaltrials.gov as NCT02032615.

BACKGROUND: Obstetric fistula has severe psychological consequences, but no evidence-based interventions exist to improve mental health in this population. This pilot trial evaluated a psychological intervention for women receiving surgical care for obstetric fistula. METHODS: A parallel two-armed pilot RCT was conducted between 2014 and 2016. The intervention was six individual sessions, based on psychological theory and delivered by a nurse facilitator. The study was conducted at a tertiary hospital in Moshi, Tanzania. Women were eligible if they were over age 18 and admitted to the hospital for surgical repair of an obstetric fistula. Sixty participants were randomized to the intervention or standard of care. Surveys were completed at baseline, post-treatment (before discharge), and 3 months following discharge. Standardized scales measured depression, anxiety, traumatic stress, and self-esteem. Feasibility of an RCT was assessed by participation and retention. Feasibility and acceptability of the intervention were assessed by fidelity, attendance, and participant ratings. Potential efficacy was assessed by exploratory linear regression and clinical significance analysis. RESULTS: Eighty-five percent met criteria for mental health dysfunction at enrollment. All eligible patients enrolled, with retention 100% post and 73% at 3 months. Participants rated the intervention acceptable and beneficial. There were sharp and meaningful improvements in mental health outcomes over time, with no evidence of differences by condition. CONCLUSIONS: A nurse-delivered mental health intervention was feasible to implement as part of in-patient clinical care and regarded positively. Mental health treatment in this population is warranted given high level of distress at presentation to care. TRIAL REGISTRATION: ClinicalTrials.Gov NCT01934075.
RESUMO
OBJECTIVE: To assess relationships between self-assessed control over life events, subjective beliefs about longevity, time and risk preference, and other factors on use of recommended care for diabetes mellitus (DM), self-assessed control of diabetes, general health, and laboratory measures of HbA1c levels. DATA SOURCES: Health and Retirement Study (HRS) and 2003 HRS Diabetes Study (HRS-DS). STUDY DESIGN: We used logit and ordered logit analyses to assess use of recommended care, and subjective and objective measures of health outcomes. DATA COLLECTION: Secondary analysis of HRS and HRS-DS data. PRINCIPAL FINDINGS: Individuals with higher self-assessed control over life events and higher subjective probabilities of living 10 years engaged in more recommended DM care practices and had better self-assessed DM control and general health. However, these beliefs did not influence HbA1c levels. More highly educated and cognitively able persons were more likely to follow care recommendations. There were differences by race/ethnicity in health outcomes, but not in health investment among Hispanics. CONCLUSIONS: Individuals' beliefs about control over life events and longevity influenced health investment and subjective health outcomes, although these beliefs did not translate into differences in HbA1c levels. Hispanics may realize lower returns on health investments, at least for diabetes care.
