Emergency peripartum hysterectomies at Muhimbili National Hospital, Tanzania: Review of cases from 2003 to 2007

A retrospective review of all cases of emergency peripartum hysterectomy performed between January 1, 2003 and December 31, 2007 at Muhimbili National Hospital was done to determine the incidence, indications and complications, background characteristics, antenatal care attendance, referral status, and maternal and foetal outcomes. There were 55,152 deliveries during the study period and 165 cases of emergency peripartum hysterectomy, giving the incidence of emergency peripartum hysterectomy of 3 per 1000 deliveries. The main indication was uterine rupture (79%) followed by severe post-partum haemorrhage due to uterine atony (12.7%). The case fatality rate was 10.3% where as perinatal mortality rate was 7.7 per 1000 deliveries. The common complication identified intraoperatively was severe haemorrhage which accounted for 39.4% where as intensive care unit admissions (14.4%) and febrile morbidity (12.4%) were common after the operation. Blood was ordered in all cases but in 31 cases it was indicated that it was not available. Seventy nine patients received blood transfusion with the maximum number of units given to one patient being eight. Twenty two patients were given fresh frozen plasma (FFP), the median number of units given was two (range = 1– 6). In conclusion, emergency peripartum hysterectomy is a life saving procedure and very common at MNH. The most common indication was ruptured uterus followed by severe postpartum haemorrhage. More than half of the patients underwent emergency peripartum hysterectomy were referred from other health facilities with ruptured or suspected ruptured uterus. The procedure was associated with unacceptably high maternal and perinatal morbidity and mortality

Risks for preterm delivery and low birth weight are independently increased by severity of maternal anaemia

OBJECTIVE: To estimate the effect of the severity of maternal anaemia on various perinatal outcomes. DESIGN: A cross-sectional study. SETTING: Labour Ward, Muhimbili National Hospital, Dar es Salaam, Tanzania. METHOD: The haemoglobin of eligible pregnant women admitted for delivery between 15 November 2002 and 15 February 2003 was measured. Data on socio-demographic characteristics, iron supplementation, malaria prophylaxis, blood transfusion during current pregnancy, and current and previous pregnancy outcomes were collected and analysed. Anaemia was classified according to the World Health Organization (WHO) standards: normal - Hb \u3e11.0 g/dl; mild - Hb 9.0 - 10.9 g/dl; moderate - Hb 7.0 - 8.9 g/dl; and severe - Hb \u3c7.0 g/dl. Logistic regression analysis was performed to estimate the severity of anaemia. The following outcome measures were used: preterm delivery (\u3c37 weeks), Apgar score, stillbirth, early neonatal death, low birth weight (LBW) (\u3c2 500 g) and very low birth weight (VLBW) (\u3c1 500 g). RESULTS: A total of 1 174 anaemic and 547 non-anaemic women were enrolled. Their median age was 24 years (range 14 - 46 years) and median parity was 2 (range 0 - 17). The prevalence of anaemia and severe anaemia was 68% and 5.8%, respectively. The risk of preterm delivery increased significantly with the severity of anaemia, with odds ratios of 1.4, 1.4 and 4.1 respectively for mild, moderate and severe anaemia. The corresponding risks for LBW and VLBW were 1.2 and 1.7, 3.8 and 1.5, and 1.9 and 4.2 respectively. CONCLUSION: The risks of preterm delivery and LBW increased in proportion to the severity of maternal anaemia

Grand multiparity: is it still a risk in pregnancy?

Background The association of grand multiparity and poor pregnancy outcome has not been consistent for decades. Classifying grand multiparous women as a high-risk group without clear evidence of a consistent association with adverse outcomes can lead to socioeconomic burdens to the mother, family and health systems. We compared the maternal and perinatal complications among grand multiparous and other multiparous women in Dar es Salaam in Tanzania. Methods A cross-sectional study was undertaken at Muhimbili National Hospital (MNH). A standard questionnaire enquired the following variables: demographic characteristics, antenatal profile and detected obstetric risk factors as well as maternal and neonatal risk factors. Predictors of adverse outcomes in relation to grand multiparous women were assessed at p = 0.05. Results Grand multiparas had twice the likelihood of malpresentation and a threefold higher prevalence of meconium-stained liquor and placenta previa compared with lower-parity women even when adjusted for age. Neonates delivered by grand multiparous women (12.1%) were at three-time greater risk of a low Apgar score compared with lower-parity women (5.4%) (odds ratio (OR), 2.9; 95% confidence interval (CI), 1.5–5.0). Grand multiparity and low birth weight were independently associated with a low Apgar score (OR, 2.4; 95%, CI 1.4–4.2 for GM; OR, 4.2; 95% CI, 2.3–7.8) for low birth weight. Conclusion Grand multiparity remains a risk in pregnancy and is associated with an increased prevalence of maternal and neonatal complications (malpresentation, meconium-stained liquor, placenta previa and a low Apgar score) compared with other multiparous women who delivered at Muhimbili National Hospital

Efficiency of antenatal care and childbirth services in selected primary health care facilities in rural Tanzania : a cross-sectional study

Background: Cost studies are paramount for demonstrating how resources have been spent and identifying opportunities for more efficient use of resources. The main objective of this study was to assess the actual dimension and distribution of the costs of providing antenatal care (ANC) and childbirth services in selected rural primary health care facilities in Tanzania. In addition, the study analyzed determining factors of service provision efficiency in order to inform health policy and planning. Methods: This was a retrospective quantitative cross-sectional study conducted in 11 health centers and dispensaries in Lindi and Mtwara rural districts. Cost analysis was carried out using step down cost accounting technique. Unit costs reflected efficiency of service provision. Multivariate regression analysis on the drivers of observed relative efficiency in service provision between the study facilities was conducted. Reported personnel workload was also described. Results: The health facilities spent on average 7 USD per capita in 2009. As expected, fewer resources were spent for service provision at dispensaries than at health centers. Personnel costs contributed a high approximate 44% to total costs. ANC and childbirth consumed approximately 11% and 12% of total costs; and 8% and 10% of reported service provision time respectively. On average, unit costs were rather high, 16 USD per ANC visit and 79.4 USD per childbirth. The unit costs showed variation in relative efficiency in providing the services between the health facilities. The results showed that efficiency in ANC depended on the number of staff, structural quality of care, process quality of care and perceived quality of care. Population-staff ratio and structural quality of basic emergency obstetric care services highly influenced childbirth efficiency. Conclusions: Differences in the efficiency of service provision present an opportunity for efficiency improvement. Taking into consideration client heterogeneity, quality improvements are possible and necessary. This will stimulate utilization of ANC and childbirth services in resource-constrained health facilities. Efficiency analyses through simple techniques such as measurement of unit costs should be made standard in health care provision, health managers can then use the performance results to gauge progress and reward efficiency through performance based incentives

Comparison of common adverse neonatal outcomes among preterm and term infants at the National Referral Hospital in Tanzania: a case-control study

Background: Neonatal period is a critical period in a child’s heath because it is associated with higher risk of adverse health outcomes. The objective of this study was to assess common adverse health outcomes and compare the risk of such outcomes between preterm and term neonates, in Tanzania. Methods: This was a case-control study involving infants admitted at Muhimbili National Hospital between August and October 2020. About 222 pairs of preterm and term infants were followed until discharge. Logistic regression was used to compare risk of health outcomes. Statistical significance was achieved at p–value < 0.05 and 95% confidence interval. Result: Preterm neonates had increased risk of mortality (OR = 7.2, 95% CI: 3.4-15.1), apnea (OR = 4.7, 95% CI: 3.4 – 15.1), respiratory distress syndrome (OR = 10.9, 95% CI: 6.1 – 19.6), necrotizing enterocolitis (OR = 5.5, 95% CI: 1.2 – 25.3), anemia (OR = 4.3, 95% CI: 2.8 – 6.6), pneumonia (OR = 2.7, 95% CI: 1.6 – 4.6) and sepsis (OR = 2.6, 95% CI: 1.7 – 3.9). No difference in risk of intraventricular hemorrhage, patent ductus arteriosus and jaundice was observed. Conclusion: For promoting neonates' health, prevention and treatment of the higher risk adverse neonatal outcomes should be prioritized

Maternal death surveillance and response in Tanzania: comprehensiveness of narrative summaries and action points from maternal death reviews.

BACKGROUND: Maternal deaths reviews are proposed as one strategy to address high maternal mortality in low and middle-income countries, including Tanzania. Review of maternal deaths relies on comprehensive documentation of medical records that can reveal the sequence of events leading to death. The World Health Organization's and the Tanzanian Maternal Death and Surveillance (MDSR) system propose the use of narrative summaries during maternal death reviews for discussing the case to categorize causes of death, identify gaps in care and recommend action plans to prevent deaths. Suggested action plans are recommended to be Specific, Measurable, Attainable, Relevant and Time bound (SMART). To identify gaps in documenting information and developing recommendations, comprehensiveness of written narrative summaries and action plans were assessed. METHODS: A total of 76 facility maternal deaths that occurred in two regions in Southern Tanzania in 2018 were included for analysis. Using a prepared checklist from Tanzania 2015 MDSR guideline, we assessed comprehensiveness by presence or absence of items in four domains, each with several attributes. These were socio-demographic characteristics, antenatal care, referral information and events that occurred after admission. Less than 75% completeness of attributes in all domains was considered poor while 95% and above were good/comprehensive. Action plans were assessed by application of SMART criteria and according to the place of planned implementation (community, facility or higher level of health system). RESULTS: Almost half of narrative summaries (49%) scored poor, and only1% scored good/comprehensive. Summaries missed key information such as demographic characteristics, time between diagnosis of complication and commencing treatment (65%), investigation results (47%), summary of case evolution (51%) and referral information (47%). A total of 285 action points were analysed. Most action points, 242(85%), recommended strategies to be implemented at health facilities and were mostly about service delivery, 120(42%). Only 42% (32/76) of the action points were deemed to be SMART. CONCLUSIONS: Abstraction of information to prepare narrative summaries used in the MDSR system is inadequately done. Most recommendations were unspecific with a focus on improving quality of care in health facilities

Causes of maternal deaths and delays in care: comparison between routine maternal death surveillance and response system and an obstetrician expert panel in Tanzania.

BACKGROUND: To reduce maternal mortality Tanzania introduced Maternal Death Surveillance and Response (MDSR) system in 2015 as recommended by World Health Organization (WHO). All health facilities are to notify and review all maternal deaths inorder to recommend quality improvement actions to reduce deaths in future. The system relies on consistent and correct categorization of causes of maternal deaths and three phases of delays. To assess its adequacy we compared the routine MDSR categorization of causes of death and three phases of delays to those assigned by an independent expert panel with additional information from Verbal Autopsy (VA). METHODS: Our cross-sectional study included 109 reviewed maternal deaths from two regions in Tanzania for the year 2018. We abstracted the underlying medical causes of death and the three phases of delays from MDSR system records. We interviewed bereaved families using the standard WHO VA questionnaire. The obstetrician expert panel assigned underlying causes of death based on information from medical files and VA according to International Classification of Disease to Death in Pregnancy Childbirth and Puerperium (ICD-MM). They assigned causes to nine ICD-MM groups and identified the three phases of delays. We used Cohen's K statistic to compare causes of deaths and delays categorization. RESULTS: Comparison of underlying causes was done for 99 deaths. While 109 and 84 deaths for expert panel and MDSR respectively were analyzed for delays because of missing data in MDSR system. Expert panel and MDSR system assigned the same underlying causes in 64(64.6%) deaths (K statistic 0.60). Agreement increased in 80 (80.8%) when causes were assigned by ICD-MM groups (K statistic 0.76). The obstetrician expert panel identified phase one delays in 74 (67.9%), phase two in 24 (22.0%) and phase three delays in all 101 (100%) deaths that were assessed for this delay while MDSR system identified delays in 42 (50.0%), 10 (11.9%) and 78 (92.9%).The expert panel found human errors in management in 94 (93.1%) while MDSR system reported in 53 (67.9%) deaths. CONCLUSIONS: MDSR committees performed reasonably well in assigning underlying causes of death. The obstetrician expert panel found more delays than reported in MDSR system indicating difficulties within MDSR teams to critically review deaths

Mismatched ambition, execution and outcomes: implementing maternal death surveillance and response system in Mtwara region, Tanzania

BACKGROUND: Since 2015, Tanzania has been implementing the Maternal Death Surveillance and Response (MDSR) system. The system employs interactions of health providers and managers to identify, notify and review maternal deaths and recommend strategies for preventing further deaths. We aimed to analyse perceptions and experiences of health providers and managers in implementing the MDSR system. METHODS: An exploratory qualitative study was carried out with 30 purposively selected health providers and 30 health managers in four councils from the Mtwara region between June and July 2020. Key informant interviews and focus group discussions were used to collect data. Inductive thematic analysis was used to analyse data. RESULTS: Two main themes emerged from this study: 'Accomplishing by ambitions' and 'A flawed system'. The themes suggest that health providers and managers have a strong desire to make the MDSR system work by making deliberate efforts to implement it. They reported working hard to timely notify, review death and implement action plans from meetings. Health providers and managers reported that MDSR has produced changes in care provision such as behavioural changes towards maternal care, increased accountability and policy changes. The system was however flawed by lack of training, organisational problems, poor coordination with other reporting and quality improvements systems, assigning blame and lack of motivation. CONCLUSION: The implementation of the MDSR system in Tanzania faces systemic, contextual and individual challenges. However, our results indicate that health providers and managers are willing and committed to improve service delivery to avoid maternal deaths. Empowering health providers and managers by training and addressing the flaws will improve the system and quality of care

Cost-effectiveness of an electronic clinical decision support system for improving quality of antenatal and childbirth care in rural Tanzania: an intervention study

Background: QUALMAT project aimed at improving quality of maternal and newborn care in selected health care facilities in three African countries. An electronic clinical decision support system was implemented to support providers comply with established standards in antenatal and childbirth care. Given that health care resources are limited and interventions differ in their potential impact on health and costs (efficiency), this study aimed at assessing cost-effectiveness of the system in Tanzania. Methods: This was a quantitative pre- and post- intervention study involving 6 health centres in rural Tanzania. Cost information was collected from health provider’s perspective. Outcome information was collected through observation of the process of maternal care. Incremental cost-effectiveness ratios for antenatal and childbirth care were calculated with testing of four models where the system was compared to the conventional paper-based approach to care. One-way sensitivity analysis was conducted to determine whether changes in process quality score and cost would impact on cost-effectiveness ratios. Results: Economic cost of implementation was 167,318 USD, equivalent to 27,886 USD per health center and 43 USD per contact. The system improved antenatal process quality by 4.5% and childbirth care process quality by 23.3% however these improvements were not statistically significant. Base-case incremental cost-effectiveness ratios of the system were 2469 USD and 338 USD per 1% change in process quality for antenatal and childbirth care respectively. Cost-effectiveness of the system was sensitive to assumptions made on costs and outcomes. Conclusions: Although the system managed to marginally improve individual process quality variables, it did not have significant improvement effect on the overall process quality of care in the short-term. A longer duration of usage of the electronic clinical decision support system and retention of staff are critical to the efficiency of the system and can reduce the invested resources. Realization of gains from the system requires effective implementation and an enabling healthcare system. Trial registration: Registered clinical trial at www.clinicaltrials.gov (NCT01409824).
