ABSTRACT

In rural sub-Saharan Africa, preventable delays in accessing emergency care remain a dominant factor in maternal and neonatal deaths. The MOMENTUM study is a pragmatic cohort investigation designed to measure the "Three Delays", i.e. delays in recognizing need for care (Type 1), reaching care (Type 2), and receiving care (Type 3) within a remote island health system on Lake Victoria, Kenya. The study utilizes an adaptive methodology to provide actionable data for a locally-directed "Health Navigation" intervention. We present analysis of 56 maternal and neonatal emergency cases occurring between January 2019 and February 2020. The mean Total Delay Interval (Type 1-3) reported was 39.3 ± 32.3hours. Notably, 18 cases in this cohort resulted in a neonatal (n = 16) or maternal death (n = 2). Sub-analysis indicates significant delay interval reductions associated with involvement of a "Health Navigator" in emergency care coordination for Type 2 Delay Intervals (0.5 ± 0.3 vs. 1.2 ± 1.1 hrs., p = 0.002) and Type 3 Delay Intervals (17.9 ± 14.1 vs. 32.9 ± 33.7 hrs., p = 0.030). Prolonged delays, complex barriers, and high mortality highlight the fraught nature of maternal emergencies in this remote setting. We discuss practical considerations for application of the Three Delays model, and avenues for further investigation.

ABSTRACT

Despite worldwide improvements in maternal and infant mortality, mothers and babies in remote, low-resource communities remain disproportionately vulnerable to adverse health outcomes. In these settings, delays in accessing emergency care are a major driver of poor outcomes. The 'Three Delays' model is now widely utilised to conceptualise these delays. However, in out-of-hospital contexts, operational and methodological constraints present major obstacles in practically quantifying the 'Three Delays'. Here, we describe a novel protocol for the MOMENTUM study (Monitoring of Maternal Emergency Navigation and Triage on Mfangano), a 12-month cohort design to assess delays during obstetric and neonatal emergencies within the remote villages of Mfangano Island Division, Lake Victoria, Kenya. This study also evaluates the preliminary impact of a community-based intervention called the 'Mfangano Health Navigation' programme. Utilising participatory case audits and contextually specific chronological reference strategies, this study combines quantitative tools with deeper-digging qualitative inquiry. This pragmatic design was developed to empower local research staff and study participants themselves as assets in unravelling the complex socio-economic, cultural, and logistical dynamics that contribute to delays, while providing real-time feedback for locally driven intervention. We present our methods as an adaptive framework for researchers grappling with similar challenges across fragmented, rural health landscapes.

ABSTRACT

STUDY OBJECTIVE: Hyperglycemia is frequently encountered in the emergency department (ED), and there is no consensus on optimal care before discharge. The importance of glucose reduction in the ED is unknown. We seek to determine whether an association exists between discharge glucose and 7-day adverse outcomes. METHODS: A cohort design with retrospective chart review was conducted at a high-volume urban ED. Patients were included if any glucose level was greater than or equal to 400 mg/dL and they were discharged from the ED. Generalized estimating equation models were created for the 7-day outcomes with a primary predictor of discharge glucose. RESULTS: The cohort consisted of 422 patients with 566 ED encounters. Mean arrival and discharge glucose were 491 mg/dL (SD 82 mg/dL) and 334 mg/dL (SD 101 mg/dL), respectively. In the 7-day follow-up period, 62 (13%) and 36 (7%) patients had a repeat ED visit for hyperglycemia and were hospitalized, respectively. Two patients had diabetic ketoacidosis. After adjustment for arrival glucose, whether a chemistry panel was obtained, amount of intravenous fluids administered, and amount of subcutaneous insulin administered, discharge glucose was not associated with repeat ED visit for hyperglycemia (adjusted odds ratio 0.997; 95% confidence interval 0.993 to 1.001) or hospitalization for any reason (adjusted odds ratio 0.998; 95% confidence interval 0.995 to 1.002). CONCLUSION: ED discharge glucose in patients with moderate to severe hyperglycemia was not associated with 7-day outcomes of repeat ED visit for hyperglycemia or hospitalization. Attaining a specific glucose goal before discharge in patients with hyperglycemia may be less important than traditionally thought.

ABSTRACT

BACKGROUND: In sub-Saharan Africa, failure to initiate and sustain HIV treatment contributes to significant health, psychosocial, and economic impacts that burden not only infected individuals but diverse members of their social networks. Yet, due to intense stigma, the responsibility for managing lifelong HIV treatment rests solely, and often secretly, with infected individuals. We introduce the concept of "HIV risk induction" to suggest that social networks of infected individuals share a vested interest in improving long-term engagement with HIV care, and may represent an underutilized resource for improving HIV/AIDS outcomes within high prevalence populations. METHODS: In 2012, we implemented a 'microclinic' intervention to promote social network engagement in HIV/AIDS care and treatment. A microclinic is a therapy management collective comprised of a small group of neighbors, relatives, and friends who are trained as a team to provide psychosocial and adherence support for HIV-infected members. Our study population included 369 patients on ART and members of their social networks on Mfangano Island, Kenya, where HIV prevalence approaches 30%. Here we report qualitative data from 18 focus group discussions conducted with microclinic participants (n = 82), community health workers (n = 40), and local program staff (n = 39). RESULTS: Participants reported widespread acceptability and enthusiasm for the microclinic intervention. Responses highlight four overlapping community transformations regarding HIV care and treatment, namely (1) enhanced HIV treatment literacy (2) reduction in HIV stigma, (3) improved atmosphere for HIV status disclosure and (4) improved material and psychosocial support for HIV-infected patients. Despite challenges, participants describe an emerging sense of "collective responsibility" for treatment among HIV-infected and HIV-uninfected members of social networks. DISCUSSION: The lived experiences and community transformations highlighted by participants enrolled in this social network intervention in Western Kenya suggest opportunities to reframe the continuum of HIV care from a secretive individual journey into a network-oriented cycle of engagement.

ABSTRACT

BACKGROUND: Despite progress in the global scale-up of antiretroviral therapy, sustained engagement in HIV care remains challenging. Social capital is an important factor for sustained engagement, but interventions designed to harness this powerful social force are uncommon. METHODS: We conducted a quasiexperimental study evaluating the impact of the Microclinic Social Network intervention on engagement in HIV care and medication adherence on Mfangano Island, Kenya. The intervention was introduced into 1 of 4 similar communities served by this clinic; comparisons were made between communities using an intention-to-treat analysis. Microclinics, composed of patient-defined support networks, participated in 10 biweekly discussion sessions covering topics ranging from HIV biology to group support and group HIV status disclosure. Nevirapine concentrations in hair were measured before and after study. RESULTS: One hundred thirteen (74%) intervention community participants joined a microclinic group, 86% of whom participated in group HIV status disclosure. Over 22-month follow-up, intervention community participants experienced one-half the rate of ≥ 90-day clinic absence as those in control communities (adjusted hazard ratio: 0.48; 95% confidence interval: 0.25 to 0.92). Nevirapine hair levels declined in both study arms; in adjusted linear regression analysis, the decline was 6.7 ng/mg less severe in the intervention arm than control arm (95% confidence interval: -2.7 to 16.1). CONCLUSIONS: The microclinic intervention is a promising and feasible community-based strategy to improve long-term engagement in HIV care and possibly medication adherence. Reducing treatment interruptions using a social network approach has important implications for individual patient virologic suppression, morbidity, and mortality and for broader community empowerment and engagement in healthcare.

ABSTRACT

Antiretroviral hair levels objectively quantify drug exposure over time and predict virologic responses. We assessed the acceptability and feasibility of collecting small hair samples in a rural Kenyan cohort. Ninety-five percentage of participants (354/373) donated hair. Although median self-reported adherence was 100% (interquartile range, 96%-100%), a wide range of hair concentrations likely indicates overestimation of self-reported adherence and the advantages of a pharmacologic adherence measure. Higher nevirapine hair concentrations observed in women and older adults require further study to unravel behavioral versus pharmacokinetic contributors. In resource-limited settings, hair antiretroviral levels may serve as a low-cost quantitative biomarker of adherence.

ABSTRACT

OBJECTIVE: To determine whether the use of cardiocerebral resuscitation (CCR) or AHA/ERC 2005 Resuscitation Guidelines improved patient outcomes from out-of-hospital cardiac arrest (OHCA) compared to older guidelines. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE, EMBASE, Web of Science and the Cochrane Library databases. We also hand-searched study references and consulted experts. STUDY SELECTION: Design: randomised controlled trials and observational studies. POPULATION: OHCA patients, age >17 years. COMPARATORS: 'Control' protocol versus 'Study' protocol. 'Control' protocol defined as AHA/ERC 2000 Guidelines for cardiopulmonary resuscitation (CPR). 'Study' protocol defined as AHA/ERC 2005 Guidelines for CPR, or a CCR protocol. OUTCOME: Survival to hospital discharge. QUALITY: High-quality or medium-quality studies, as measured by the Newcastle Ottawa Scale using predefined categories. RESULTS: Twelve observational studies met inclusion criteria. All the three studies using CCR demonstrated significantly improved survival compared to use of AHA 2000 Guidelines, as did five of the nine studies using AHA/ERC 2005 Guidelines. Pooled data demonstrate that use of a CCR protocol has an unadjusted OR of 2.26 (95% CI 1.64 to 3.12) for survival to hospital discharge among all cardiac arrest patients. Among witnessed ventricular fibrillation/ventricular tachycardia (VF/VT) patients, CCR increased survival by an OR of 2.98 (95% CI 1.92 to 4.62). Studies using AHA/ERC 2005 Guidelines showed an overall trend towards increased survival, but significant heterogeneity existed among these studies. CONCLUSIONS: We demonstrate an association with improved survival from OHCA when CCR protocols or AHA/ERC 2005 Guidelines are compared to use of older guidelines. In the subgroup of patients with witnessed VF/VT, there was a threefold increase in OHCA survival when CCR was used. CCR appears to be a promising resuscitation protocol for Emergency Medical Services providers in increasing survival from OHCA. Future research will need to be conducted to directly compare AHA/ERC 2010 Guidelines with the CCR approach.
