There is a paucity of recent prospective data on the incidence of postpartum infections and associated risk factors in sub-Saharan Africa. Retrospective studies estimate that puerperal sepsis causes approximately 10% of maternal deaths in Africa. We enrolled 4231 women presenting to a Ugandan regional referral hospital for delivery or postpartum care into a prospective cohort and measured vital signs postpartum. Women developing fever (> 38.0 °C) or hypothermia (< 36.0 °C) underwent symptom questionnaire, structured physical exam, malaria testing, blood, and urine cultures. Demographic, treatment, and post-discharge outcomes data were collected from febrile/hypothermic women and a random sample of 1708 normothermic women. The primary outcome was in-hospital postpartum infection. Multivariable logistic regression was used to determine factors independently associated with postpartum fever/hypothermia and with confirmed infection. Overall, 4176/4231 (99%) had ≥1 temperature measured and 205/4231 (5%) were febrile or hypothermic. An additional 1708 normothermic women were randomly selected for additional data collection, for a total sample size of 1913 participants, 1730 (90%) of whom had complete data. The mean age was 25 years, 214 (12%) were HIV-infected, 874 (51%) delivered by cesarean and 662 (38%) were primigravidae. Among febrile/hypothermic participants, 174/205 (85%) underwent full clinical and microbiological evaluation for infection, and an additional 24 (12%) had a partial evaluation. Overall, 84/4231 (2%) of participants met criteria for one or more in-hospital postpartum infections. Endometritis was the most common, identified in 76/193 (39%) of women evaluated clinically. Twenty-five of 175 (14%) participants with urinalysis and urine culture results met criteria for urinary tract infection. Bloodstream infection was diagnosed in 5/185 (3%) participants with blood culture results. Another 5/186 (3%) tested positive for malaria. Cesarean delivery was independently associated with incident, in-hospital postpartum infection (aOR 3.9, 95% CI 1.5–10.3, P = 0.006), while antenatal clinic attendance was associated with reduced odds (aOR 0.4, 95% CI 0.2–0.9, P = 0.02). There was no difference in in-hospital maternal deaths between the febrile/hypothermic (1, 0.5%) and normothermic groups (0, P = 0.11). Among rural Ugandan women, postpartum infection incidence was low overall, and cesarean delivery was independently associated with postpartum infection while antenatal clinic attendance was protective.

Uterine rupture is one of the most devastating complications of labour that exposes the mother and foetus to grave danger hence contributing to the high maternal and perinatal mortality and morbidity in Uganda. Every year, 6000 women die due to complications of pregnancy and childbirth, uterine rupture accounts for about 8% of all maternal deaths. The objective of this study was to establish the incidence of uterine rupture, predisposing factors, maternal and fetal outcomes and modes of management at a regional referral university hospital in South-western Uganda. Case–control design of women with uterine rupture during 2005–2006. Controls were women who had spontaneous vaginal delivery or were delivered by caesarean section without uterine rupture as a complication. For every case, three consecutive in-patient chart numbers were picked and retrieved as controls. All available case files, labour ward and theater records were reviewed. A total of 83 cases of uterine rupture out of 10940 deliveries were recorded giving an incidence of uterine rupture of 1 in 131 deliveries. Predisposing factors for uterine rupture were previous cesarean section delivery(OR 5.3 95% CI 2.7-10.2), attending < 4 antenatal visits (OR 3.3 95% CI 1.6-6.9), parity ≥ 5(OR 3.67 95% CI 2.0-6.72), no formal education (OR 2.0 95% CI 1.0-3.9), use of herbs (OR15.2 95% CI 6.2-37.0), self referral (OR 6.1 95% CI 3.3-11.2) and living in a distance >5 km from the facility (OR 10.86 95% CI 1.46-81.03). There were 106 maternal deaths during the study period giving a facility maternal mortality ratio of 1034 /100,000 live births, there were 10 maternal deaths due to uterine rupture giving a case fatality rate of 12%. Uterine rupture still remains one of the major causes of maternal and newborn morbidity and mortality in Mbarara Regional referral Hospital in Western Uganda. Promotion of skilled attendance at birth, use of family planning among those at high risk, avoiding use of herbs during pregnancy and labour, correct use of partograph and preventing un necesarry c-sections are essential in reducing the occurences of uterine repture.

Background: Life-threatening obstetric complications usually lead to the need for referral and constitute the commonest direct causes of maternal deaths. Urgent management of referrals can potentially lower the maternal mortality rate. We explored the experiences of women referred with obstetric emergencies to Mbarara Regional Referral Hospital (MRRH) in Uganda, in order to identify barriers and facilitating factors. Methods: This was an exploratory qualitative study. In-depth interviews (IDIs) were conducted with 10 postnatal women and 2 attendants as key informants. We explored health system and client related factors to understand how these could have facilitated or hindered the referral process. Data was analyzed deductively employing the constructs of the Andersen Healthcare Utilization model. Results: Women experienced transport, care delays and inhumane treatment from health care providers (HCPs). The obstetric indications for referral were severe obstructed labor, ruptured uterus, and transverse lie in advanced labor, eclampsia and retained second twin with intrapartum hemorrhage. The secondary reasons for referral included; non-functional operating theatres due to power outages, unsterilized caesarian section instruments, no blood transfusion services, stock outs of emergency drugs, and absenteeism of HCPs to perform surgery. Four (4) themes emerged; enablers, barriers to referral, poor quality of care and poor health facility organization. Most referring health facilities were within a 30–50 km radius from MRRH. Delays to receive emergency obstetric care (EMOC) led to acquisition of in-hospital complications and eventual prolonged hospitalization. Enablers to referral were social support, financial preparation for birth and birth companion’s knowledge of danger signs. Conclusion: The experience of obstetric referral for women was largely unpleasant due to delays and poor quality of care which contributed to perinatal mortality and maternal morbidities. Training HCPs in respectful maternity care (RMC) may improve quality of care and foster positive postnatal client experiences. Refresher sessions on obstetric referral procedures for HCPs are suggested. Interventions to improve the functionality of the obstetric referral pathway for rural south-western Uganda should be explored.

INTRODUCTION: Positive HIV results disclosure plays a significant role in the successful prevention and care of HIV infected patients. It provides significant social and health benefits to the individual and the community. Non-disclosure is one of the contextual factors driving the HIV epidemic in Uganda. Study objectives: to determine the frequency of HIV disclosure, associated factors and disclosure outcomes among HIV positive pregnant women at Mbarara Hospital, southwestern Uganda. METHODS: a cross-sectional study using quantitative and qualitative methods among a group of HIV positive pregnant women attending antenatal clinic was done and consecutive sampling conducted. RESULTS: the total participant recruitment was 103, of which 88 (85.4%) had disclosed their serostatus with 57% disclosure to their partners. About 80% had disclosed within less than 2 months of testing HIV positive. Reasons for disclosure included their partners having disclosed to them (27.3%), caring partners (27.3%) and encouragement by health workers (25.0%). Following disclosure, 74%) were comforted and 6.8% were verbally abused. Reasons for non-disclosure were fear of abandonment (33.3%), being beaten (33.3%) and loss of financial and emotional support (13.3%). The factors associated with disclosure were age 26-35 years (OR 3.9, 95% CI 1.03-15.16), primary education (OR 3.53, 95%CI 1.10-11.307) and urban dwelling (OR 4.22, 95% CI 1.27-14.01). CONCLUSION: participants disclosed mainly to their partners and were comforted and many of them were encouraged by the health workers. There is need to optimize disclosure merits to enable increased participation in treatment and support programs.

Introduction: In resource limited settings, the highest burden of adverse maternal-fetal outcomes at referral hospitals is registered from emergency obstetric referrals from lower health facilities. Implementation of referral protocols has not been optimally successful possibly attributed to lack of understanding of profile of obstetric referrals and local challenges faced during implementation process. Objective: This study described the profile of emergency obstetric referrals, challenges faced in implementation of obstetric referral processes and explored self-reported solutions by health workers. Methods: This was a mixed methods study done at Mbarara Regional Referral Hospital (MRRH) and health centre IVs in South-Western Uganda. We consecutively recruited emergency obstetric referrals from Isingiro district for delivery at MRRH. Using a pre-tested questionnaire, we collected demographics, obstetric and referral characteristics. We described the profile of referrals using frequencies and proportions based on demographics, obstetric and referral characteristics. We conducted focus group discussions and in-depth interviews with health workers using discussion/interview guides. Using thematic analysis, we ascertained the challenges and health worker self-reported solutions. Results: We recruited 161 referrals: 104(65%) were below 26 years, 16(10%) had no formal education, 11(7%) reported no income, 151(94%) had no professional-escort, 137(85%) used taxis, 151(96%) were referred by midwives. Common diagnoses were previous cesarean scar (24% [n=39]) and prolonged labour (21% [n=33]). There was no communication prior to referral and no feedback from MRRH to lower health facilities. Other challenges included inconsistencies of ambulance and anesthesia services, electric power, medical supplies, support supervision, and harassment by colleagues. Self-reported solutions included the use of phone call technology for communication, audit meetings, support supervision and increasing staffing level. Conclusion: Most referrals are of poor social-economic status, use taxis, and lack professional-escort. Health workers suffer harassment, lack of communication and shortage of supplies. We need to experiment whether mobile phone technology could solve the communication gap.

Over 3 million stillbirths occur annually in sub Saharan Africa; most occur intrapartum and are largely preventable. The standard of care for fetal heart rate (FHR) assessment in most sub-Saharan African settings is a Pinard Stethoscope, limiting observation to one person, at one point in time. We aimed to test the functionality and acceptability of a wireless FHR monitor that could allow for expanded monitoring capacity in rural Southwestern Uganda. In a mixed method prospective study, we enrolled 1) non-laboring healthy term pregnant women to wear the device for 30 min and 2) non-study clinicians to observe its use. The battery-powered prototype uses Doppler technology to measure fetal cardiotocographs (CTG), which are displayed via an android device and wirelessly transmit to cloud storage where they are accessible via a password protected website. Prototype functionality was assessed by the ability to obtain and transmit a 30-min CTG. Three obstetricians independently rated CTGs for readability and agreement between raters was calculated. All participants completed interviews on acceptability. Fifty pregnant women and 7 clinicians were enrolled. 46 (92.0%) CTGs were successfully recorded and stored. Mean scores for readability were 4.71, 4.71 and 4.83 (out of 5) with high agreement (intra class correlation 0.84; 95% CI 0.74 to 0.91). All pregnant women reported liking or really liking the device, as well as high levels of comfort, flexibility and usefulness of the prototype; all would recommend it to others. Clinicians described the prototype as portable, flexible, easy-to-use and a time saver. Adequate education for clinicians and women also seemed to improve correct usage and minimise concerns on safety of the device. This prototype wireless FHR monitor functioned well in a low-resource setting and was found to be acceptable and useful to both pregnant women and clinicians. The device also seemed to have potential to improve the experience of the users compared with standard of care and expand monitoring capacity in settings where bulky, wired or traditional equipment are unreliable. Further research needs to investigate the potential impact and cost of such innovations to improve perinatal outcomes.
