The use of a mobile obstetric emergency system to improve obstetric referrals in Bong County, Liberia: A pre-post study.

OBJECTIVE: Liberia experiences an unmet need for cesarean section with about 5% population coverage, lower than 9%-19% coverage associated with improved maternal and newborn outcomes. Delays in the referral process for comprehensive emergency obstetric and newborn care (CEmONC) services due to ineffective communication between a rural health facility (RHF) and a district hospital contribute to the low CS rate. This study examined the association between mobile obstetric emergency system (MORES) implementation and referral time for obstetric emergencies as well as maternal/newborn outcomes. METHODS: A pre-post descriptive analysis was conducted on data collected from 20 rural health facilities (RHFs) and two hospitals in Bong County. Women with referral data from both RHFs and hospitals were matched and information including transfer time, reasons for referral, and maternal and newborn outcomes were extracted. Descriptive analysis and logistic regression models examined the relationship between the intervention's implementation and mode of delivery, maternal outcome, newborn outcome, and transfer time from RHF to district hospital. Ethics approval was obtained from two study centers. RESULTS: Women had higher odds of undergoing a CS at endline (OR: 1.86 95% CI: 0.99-3.46) compared to baseline. Additionally, newborns had lower odds of showing non-vigorous symptoms (OR: 0.31; 95% CI: 0.14-0.68), defined as a newborn with poor respiratory effort, muscle tone, or heart rate. There was no significant association between the intervention's implementation and transfer time. CONCLUSION: The MORES intervention is a promising means to increase timely care seeking along the referral pathway which may enhance access to cesarean section as well as improved newborn outcome in low- and middle-income countries.

Are lopinavir and efavirenz serum concentrations in HIV-infected children in the therapeutic range in clinical practice?

BACKGROUND: In antiretroviral treatment the role of therapeutic drug monitoring via measurement of serum levels remains unclear, especially in children. AIM: To quantify exposure to LPV and EFV in children receiving therapy in a routine clinical setting in order to identify risk factors associated with inadequate drug exposure. METHOD: A prospective study was conducted in a routine clinical setting in Tygerberg Children's Hospital, South Africa. A total of 53 random serum levels were analyzed. Serum concentrations were determined by an established high-performance liquid chromatography method. RESULTS: Of 53 HIV-infected children treated with lopinavir (n = 29, median age 1·83 y) or efavirenz (n = 24, median age 9·3 years), 12 showed serum levels outside the therapeutic range (efavirenz) or below Cmin (lopinavir). Low bodyweight, rifampicin co-treatment, and significant comorbidity were potential risk factors for inadequate drug exposure. CONCLUSION: These findings, together with previous studies, indicate that therapeutic drug monitoring can improve the management of antiretroviral therapy in children at risk.
