Identifying risk factors for perinatal death at Tororo District Hospital, Uganda: a case-control study.

BACKGROUND: Sub-Saharan Africa faces a disproportionate burden of perinatal deaths globally. However, data to inform targeted interventions on an institutional level is lacking, especially in rural settings. The objective of this study is to identify risk factors for perinatal death at a resource-limited hospital in Uganda. METHODS: This is a retrospective case-control study at a district hospital in eastern Uganda using birth registry data. Cases were admissions with stillbirths at or beyond 24 weeks or neonatal deaths within 28 days of birth. Controls were admissions that resulted in deliveries immediately preceding and following each case. We compared demographic and obstetric factors between cases and controls to identify risk factors for perinatal death. Subgroup analysis of type of perinatal death was also performed. Chi square, Fisher's exact, t-test, and Wilcoxon-Mann-Whitney rank sum tests were utilized for bivariate analysis, and multiple logistic regression for multivariate analysis. RESULTS: From January 2014 to December 2014, there were 185 cases of perinatal death, of which 36% (n = 69) were macerated stillbirths, 40% (n = 76) were fresh stillbirths, and 25% (n = 47) were neonatal deaths. The rate of perinatal death among all deliveries at the institution was 35.5 per 1000 deliveries. Factors associated with increased odds perinatal death included: prematurity (adjusted odds ratio (aOR) 19.7, 95% confidence interval (CI) 7.2-49.2), breech presentation (aOR 7.0, CI 1.4-35.5), multiple gestation (aOR 4.0, CI 1.1-13.9), cesarean delivery (aOR 3.8, CI 2.3-6.4) and low birth weight (aOR 2.5, CI 1.1-5.3). Analysis by subtype of perinatal death revealed distinct associations with the aforementioned risk factors, in particular for antepartum hemorrhage, which was only associated with fresh stillbirths (aOR 6.7, CI 1.6-28.8), and low birth weight. CONCLUSIONS: The rate of perinatal death at our rural hospital site was higher than national targets, and these deaths were associated with prematurity, low birth weight, breech presentation, multiple gestation, and cesarean delivery. This data and the approach utilized to acquire it can be leveraged to inform targeted interventions to reduce the rate of stillbirths and neonatal deaths in similar low resource settings.

Evaluation of a Mobile Health Approach to Tuberculosis Contact Tracing in Botswana.

Tuberculosis (TB) contact tracing is typically conducted in resource-limited settings with paper forms, but this approach may be limited by inefficiencies in data collection, storage, and retrieval and poor data quality. In Botswana, we developed, piloted, and evaluated a mobile health (mHealth) approach to TB contact tracing that replaced the paper form-based approach for a period of six months. For both approaches, we compared the time required to complete TB contact tracing and the quality of data collected. For the mHealth approach, we also administered the Computer System Usability Questionnaire to 2 health care workers who used the new approach, and we identified and addressed operational considerations for implementation. Compared to the paper form-based approach, the mHealth approach reduced the median time required to complete TB contact tracing and improved data quality. The mHealth approach also had favorable overall rating, system usefulness, information quality, and interface quality scores on the Computer System Usability Questionnaire. Overall, the mHealth approach to TB contact tracing improved on the paper form-based approach used in Botswana. This new approach may similarly benefit TB contact tracing efforts in other resource-limited settings.

Perinatal outcomes and 2017 ACC/AHA blood pressure categories.

OBJECTIVE: To evaluate the association of blood pressure category < 20 weeks according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) criteria with adverse perinatal outcomes. STUDY DESIGN: A retrospective cohort study of singleton deliveries between 1/2014 and 10/2017 was undertaken. Blood pressure category assigned by 2017 ACC/AHA criteria applied to blood pressures prior to 20 weeks gestation: normal (systolic < 120 and diastolic < 80), elevated blood pressure (systolic 120-129 and diastolic < 80 mmHg), stage 1 hypertension (systolic 130-139 and/or diastolic 80-89), stage 2 hypertension (prior diagnosis of chronic hypertension or systolic ≥ 140 or diastolic ≥ 90 mmHg). MAIN OUTCOME MEASURES: The primary outcome was preeclampsia. Secondary outcomes included preterm birth and postpartum readmission. Chi-square, ANOVA and Kruskal-Wallis tests and multivariable Poisson regression were used for analysis. RESULTS: Of the 6,067 eligible pregnancies, 3,855 (63.5%) had normotensive blood pressure, 1,224 (20.2%) elevated blood pressure, 624 (10.3%) stage 1 hypertension, and 364 (6.0%) stage 2 hypertension. Compared to 4.6% prevalence of preeclampsia among normotensive pregnancies, higher categories were associated with higher preeclampsia prevalence: elevated blood pressure (10.7%, adjusted relative risk (aRR) 2.2, 95% confidence interval (CI) 1.8-2.6), stage 1 hypertension (15.1%, aRR 2.7, 95% CI 2.2-3.4) and stage 2 hypertension (38.7%, aRR 6.2, 95% CI 5.1-7.4). Non-normal categories were also associated with a higher risk of preterm birth and postpartum readmission. CONCLUSION: Patients with elevated blood pressure and stage 1 and 2 hypertension at < 20 weeks are at increased risk of adverse obstetric perinatal outcomes.

Patient and provider perspectives on preterm birth risk assessment and communication.

OBJECTIVE: To describe and compare how obstetric patients and care providers view preterm birth risk assessment and communication. METHODS: We conducted eight focus groups with obstetric patients (n = 35) and 16 qualitative interviews with obstetric providers. Grounded theory was used to identify and analyze themes. RESULTS: Patients' knowledge about preterm birth varied greatly. Similar benefits and risks of preterm birth risk counseling were discussed by patients and providers with notable exceptions: patients cited preparedness as a benefit and providers cited maternal blame, patient alienation, and estimate uncertainty as potential risks. Most patients expressed a desire to know their personalized preterm birth risk during pregnancy. Providers differed in whether they offer universal versus selective, and quantitative versus qualitative, preterm birth risk counseling. Many providers expressed concern about discussing social and structural risk factors for preterm birth. CONCLUSION: While many patients desired knowing their personalized preterm birth risk, prenatal care providers' disclosure practices vary because of uncertainty of estimates, concerns about negative consequences and challenges of addressing systemic inequities and social determinants of health. PRACTICE IMPLICATIONS: Given the existing asymmetry of information about preterm birth risk, providers should consider patient preferences regarding and potential benefits and risks of such disclosure in their practice.

A mobile health approach to tuberculosis contact tracing in resource-limited settings.

Tuberculosis remains a leading cause of morbidity and mortality worldwide. In 2011, there were 8.7 million new cases and 1.4 million deaths from the disease, with >95% of these deaths taking place in low- and middle-income countries [1]. Contact tracing prevents the spread of tuberculosis by identifying and screening a case's contacts and referring symptomatic individuals to health care providers. Traditionally, contact tracing has been conducted with paper forms, which can lead to considerable inefficiencies in data collection, storage, and retrieval. These inefficiencies are problematic as tuberculosis can continue to spread if disruption of disease transmission is delayed. Mobile health approaches to tuberculosis contact tracing remain largely unaddressed and limited to management and monitoring of multidrug-resistant tuberculosis [2].To address these limitations, a mobile health application that digitizes and automates contact tracing was developed. This poster presents work currently underway to evaluate this new approach in Botswana, which has the tenth highest incidence rate of tuberculosis in the world [3]. Operational considerations for implementing a mobile health approach to contact tracing in resource-limited settings are also presented.
