Barriers to increase surgical productivity in Sierra Leone: a qualitative study.

OBJECTIVE: To explore factors influencing surgical provider productivity and identify barriers against and opportunities to increase individual surgical productivity in Sierra Leone, in order to explain the observed increase in unmet surgical need from 92.2% to 92.7% and the decrease in surgical productivity to 1.7 surgical procedures per provider per week between 2012 and 2017. DESIGN AND METHODS: This explanatory qualitative study consisted of in-depth interviews about factors influencing surgical productivity in Sierra Leone. Interviews were analysed with a thematic network analysis and used to develop a conceptual framework. PARTICIPANTS AND SETTING: 21 surgical providers and hospital managers working in 12 public and private non-profit hospitals in all regions in Sierra Leone. RESULTS: Surgical providers in Sierra Leone experience a broad range of factors within and outside the health system that influence their productivity. The main barriers involve both patient and facility financial constraints, lack of equipment and supplies, weak regulation of providers and facilities and a small surgical workforce, which experiences a lack of recognition. Initiation of a Free Health Care Initiative for obstetric and paediatric care, collaborations with partners or non-governmental organisations, and increased training opportunities for highly motivated surgical providers are identified as opportunities to increase productivity. DISCUSSION: Broader nationwide health system strengthening is required to facilitate an increase in surgical productivity and meet surgical needs in Sierra Leone. Development of a national strategy for surgery, obstetrics and anaesthesia, including methods to reduce financial barriers for patients, improve supply-mechanisms and expand training opportunities for new and established surgical providers can increase surgical capacity. Establishment of legal frameworks and appropriate remuneration are crucial for sustainability and retention of surgical health workers.

Catastrophic expenditure and impoverishment after caesarean section in Sierra Leone: An evaluation of the free health care initiative.

BACKGROUND: Utilizing surgical services, including caesarean sections, can result in catastrophic expenditure and impoverishment. In 2010, Sierra Leone introduced the Free Health Care Initiative (FHCI), a national financial risk protection program for the most vulnerable groups. Aim of this study was to investigate catastrophic expenditure and impoverishment related to caesarean section in Sierra Leone and evaluate the impact of the FHCI. METHODS: Women who delivered by caesarean section in nine hospitals were followed up with home visits one month after surgery, and data on medical and non-medical expenditures were collected. Individual income was estimated based on household characteristics and used to determine catastrophic expenditure and impoverishment for each patient. The impact of the FHCI was assessed by comparing actual expenditure with counterfactual expenditures had the initiative not existed. RESULTS: For the 1146 patients in the study, the median expenditure was 23 (IQR 4; 56) international dollars (Int$). Patients in the poorest quintile spent a median Int$ 59 (IQR 28; 76), which was significantly more than patients in the richest quintile, who spent a median Int$ 17 (IQR 2; 38, p<0.001). Travel (32.9%) and food (28.7%) were the two largest expenses. Catastrophic expenditure was encountered by 12.0% and 4.0% (10% and 25% threshold, respectively) of the women. Without the FHCI, 66.1% and 28.8% of the women would have encountered catastrophic expenditure. CONCLUSION: Many women in Sierra Leone face catastrophic expenditure related to caesarean section, mainly through food and travel expenses, and the poor are disproportionally affected. The FHCI is effective in reducing the risk of catastrophic expenditure related to caesarean section, but many patients are still exposed to financial hardship, suggesting that additional support is needed for Sierra Leone's poorest patients.

Travel time and perinatal mortality after emergency caesarean sections: an evaluation of the 2-hour proximity indicator in Sierra Leone.

INTRODUCTION: Longer travel times are associated with increased adverse maternal and perinatal outcomes. Geospatial modelling has been increasingly used to estimate geographic proximity in emergency obstetric care. In this study, we aimed to assess the correlation between modelled and patient-reported travel times and to evaluate its clinical relevance. METHODS: Women who delivered by caesarean section in nine hospitals were followed up with home visits at 1 month and 1 year. Travel times between the location before the delivery and the facility where caesarean section was performed were estimated, based on two models (model I Ouma et al; model II Munoz et al). Patient-reported and modelled travel times were compared applying a univariable linear regression analysis, and the relation between travel time and perinatal mortality was assessed. RESULTS: The median reported travel time was 60 min, compared with 13 and 34 min estimated by the two models, respectively. The 2-hour access threshold correlated with a patient-reported travel time of 5.7 hours for model I and 1.8 hours for model II. Longer travel times were associated with transport by boat and ambulance, visiting one or two facilities before reaching the final facility, lower education and poverty. Lower perinatal mortality was found both in the group with a reported travel time of 2 hours or less (193 vs 308 per 1000 births, p<0.001) and a modelled travel time of 2 hours or less (model I: 209 vs 344 per 1000 births, p=0.003; model II: 181 vs 319 per 1000 births, p<0.001). CONCLUSION: The standard model, used to estimate geographical proximity, consistently underestimated the travel time. However, the conservative travel time model corresponded better to patient-reported travel times. The 2-hour threshold as determined by the Lancet Commission on Global Surgery, is clinically relevant with respect to reducing perinatal death, not a clear cut-off.

Lung Ultrasound for Detection of Pulmonary Complications in Critically Ill Obstetric Patients in a Resource-Limited Setting.

Critically ill parturients have an increased risk of developing pulmonary complications. Lung ultrasound (LUS) could be effective in addressing the cause of respiratory distress in resource-limited settings with high maternal mortality. We aimed to determine the frequency, timing of appearance, and type of pulmonary complications in critically ill parturients in an obstetric unit in Sierra Leone. In this prospective observational study, LUS examinations were performed on admission, after 24 and 48 hours, and in case of respiratory deterioration. Primary endpoint was the proportion of parturients with one or more pulmonary complications, stratified for the presence of respiratory distress. Secondary endpoints included timing and types of complications, and their association with "poor outcome," defined as a composite of transfer for escalation of care or death. Of 166 patients enrolled, 35 patients (21% [95% CI: 15-28]) had one or more pulmonary complications, the majority diagnosed on admission. Acute respiratory distress syndrome (period prevalence 4%) and hydrostatic pulmonary edema (4%) were only observed in patients with respiratory distress. Pneumonia (2%), atelectasis (10%), and pleural effusion (7%) were present, irrespective of respiratory distress. When ultrasound excluded pulmonary complications, respiratory distress was related to anemia or metabolic acidosis. Pulmonary complications were associated with an increased risk of poor outcome (odds ratio: 5.0; 95% CI: 1.7-14.6; P = 0.003). In critically ill parturients in a resource-limited obstetric unit, LUS contributed to address the cause of respiratory distress by identifying or excluding pulmonary complications. These were associated with a poor outcome.

The rate and perioperative mortality of caesarean section in Sierra Leone.

INTRODUCTION: Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. METHODS: We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016. All facilities performing caesarean sections were visited. Data on in-facility maternal deaths were retrieved from the Maternal Death Surveillance and Response database. Caesarean section mortality was defined as in-facility perioperative mortality. RESULTS: In 2016, there were 7357 caesarean sections in Sierra Leone. This yields a population rate of 2.9% of all live births, a 35% increase from 2012, with district rates ranging from 0.4% to 5.2%. The most common indications for surgery were obstructed labour (42%), hypertensive disorders (25%) and haemorrhage (22%). Ninety-nine deaths occurred during or after caesarean section, and the in-facility perioperative caesarean section mortality rate was 1.5% (median 0.7%, IQR 0-2.2). Haemorrhage was the leading cause of death (73%), and of those who died during or after surgery, 80% had general anaesthesia, 75% received blood transfusion and 22% had a uterine rupture diagnosed. CONCLUSIONS: The caesarean section rate has increased rapidly in Sierra Leone, but the distribution remains uneven. Caesarean section mortality is high, but there is wide variation. More access to caesarean sections for maternal and neonatal complications is needed in underserved areas, and expansion should be coupled with efforts to limit late presentation, to offer assisted vaginal delivery when indicated and to ensure optimal perioperative care.

"For this one, let me take the risk": why surgical staff continued to perform caesarean sections during the 2014-2016 Ebola epidemic in Sierra Leone.

INTRODUCTION: Routine health service provision decreased during the 2014-2016 Ebola virus disease (EVD) outbreak in Sierra Leone, while caesarean section (CS) rates at public hospitals did not. It is unknown what made staff provide CS despite the risks of contracting EVD. This study explores Sierra Leonean health worker perspectives of why they continued to provide CS. METHODS: This qualitative study documents the experiences of 15 CS providers who worked during the EVD outbreak. We interviewed surgical and non-surgical CS providers who worked at public hospitals that either increased or decreased CS volumes during the outbreak. Hospitals in all four administrative areas of Sierra Leone were included. Semistructured interviews averaged 97 min and healthcare experience 21 years. Transcripts were analysed by modified framework analysis in the NVivo V.11.4.1 software. RESULTS: We identified two themes that may explain why providers performed CS despite EVD risks: (1) clinical adaptability and (2) overcoming the moral dilemmas. CS providers reported being overworked and exposed to infection hazards. However, they developed clinical workarounds to the lack of surgical materials, protective equipment and standard operating procedures until the broader international response introduced formal personal protective equipment and infection prevention and control practices. CS providers reported that dutifulness and sense of responsibility for one's community increased during EVD, which helped them justify taking the risk of being infected. Although most surgical activities were reduced to minimise staff exposure to EVD, staff at public hospitals tended to prioritise performing CS surgery for women with acute obstetric complications. CONCLUSION: This study found that CS surgery during EVD in Sierra Leone may be explained by remarkable decisions by individual CS providers at public hospitals. They adapted practically to material limitations exacerbated by the outbreak and overcame the moral dilemmas of performing CS despite the risk of being infected with EVD.

Clinical presentation of pregnant women in isolation units for Ebola virus disease in Sierra Leone, 2014.

OBJECTIVES: To examine Ebola virus disease (EVD) symptom prevalence and EVD status among pregnant women in Ebola isolation units in Sierra Leone. METHODS: In an observational study, data were obtained for pregnant women admitted to Ebola isolation units across four districts in Sierra Leone from June 29, 2014, to December 20, 2014. Women were admitted to isolation units if they had suspected EVD exposures or fever (temperature >38°C) and three or more self-reported symptoms suggestive of EVD. Associations were examined between EVD status and each symptom using χ2 tests and logistic regression adjusting for age/labor status. RESULTS: Of 176 pregnant women isolated, 55 (32.5%) tested positive for EVD. Using logistic regression models adjusted for age, EVD-positive women were significantly more likely to have fever, self-reported fatigue/weakness, nausea/vomiting, headache, muscle/joint pain, chest pain, vaginal bleeding, unexplained bleeding, or sore throat upon admission. In models adjusted for age/labor, only women with fever or vaginal bleeding upon admission were significantly more likely to be EVD-positive. CONCLUSIONS: Several EVD symptoms and complications increased the odds of testing EVD-positive; some of these were also signs and symptoms of labor/pregnancy complications. The study results highlight the need to refine screening for pregnant women with EVD.

Maternal and perinatal outcomes in pregnant women with suspected Ebola virus disease in Sierra Leone, 2014.

OBJECTIVE: To describe maternal and perinatal outcomes among pregnant women with suspected Ebola virus disease (EVD) in Sierra Leone. METHODS: Observational investigation of maternal and perinatal outcomes among pregnant women with suspected EVD from five districts in Sierra Leone from June to December 2014. Suspected cases were ill pregnant women with symptoms suggestive of EVD or relevant exposures who were tested for EVD. Case frequencies and odds ratios were calculated to compare patient characteristics and outcomes by EVD status. RESULTS: There were 192 suspected cases: 67 (34.9%) EVD-positive, 118 (61.5%) EVD-negative, and 7 (3.6%) EVD status unknown. Women with EVD had increased odds of death (OR 10.22; 95% CI, 4.87-21.46) and spontaneous abortion (OR 4.93; 95% CI, 1.79-13.55) compared with those without EVD. Women without EVD had a high frequency of death (30.2%) and stillbirths (65.9%). One of 14 neonates born following EVD-negative and five of six neonates born following EVD-positive pregnancies died. CONCLUSION: EVD-positive and EVD-negative women with suspected EVD had poor outcomes, highlighting the need for increased attention and resources focused on maternal and perinatal health during an urgent public health response. Capturing pregnancy status in nationwide surveillance of EVD can help improve understanding of disease burden and design effective interventions.

Post-Ebola situational assessment of opportunities for capacity building at the national obstetrics and gynecology referral hospital in Sierra Leone.

OBJECTIVE: To describe a site assessment of the Princess Christian Maternity Hospital (PCMH; Freetown, Sierra Leone), the national referral center for reproductive, maternal, newborn, child and adolescent health (RMNCAH) services and logical site for focused efforts to train and expand the RMNCAH workforce in Sierra Leone. METHODS: In April 2016, a mixed-methods assessment approach was used involving facility observation and staff interviews using the WHO's Service Availability and Readiness Assessment (SARA) tool. Quantitative and qualitative data were obtained. RESULTS: PCMH had 150 inpatient beds and provided care for more than 4600 deliveries in 2015. The number of maternal deaths increased at a rate of approximately 40% per month from January 2015 to June 2016 (P=0.005). Key factors requiring attention were identified in the categories of infrastructure and supplies, RMNCAH services, and human resources. CONCLUSION: SARA provided a framework for identifying strengths and weaknesses in infrastructure and supplies, RMNCAH services, and human resources. The process described might serve as a model for evaluating obstetrics and gynecology training facilities in low- and middle-income countries. Human resources are currently insufficient for the volume and complexity of patients at PCMH. Numerous opportunities exist for strengthening healthcare services and capacity building in Sierra Leone.
