Improving quality of perinatal care through clinical audit : a study from a tertiary hospital in Dar es Salaam, Tanzania
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Perinatal audit has been tested and proved an important tool for reduction of perinatal mortality and assessment of quality of perinatal care. At Muhimbili National Hospital (MNH), a tertiary hospital in Dar es salaam, Tanzania we performed a retrospective cross-sectional study using data from an obstetrics database to classify all perinatal deaths during 1999-2003. We also determined the prevalence of anaemia in pregnancy and its impact on perinatal outcome. Furthermore, we conducted a perinatal audit to study potential determinants and causes of perinatal and neonatal deaths and their avoidability. We also assessed the quality of care of patients admitted with eclampsia using a criteria based audit. Stillbirth, early neonatal and perinatal mortality rates (PMR) were 96, 27 and 124 respectively. A large proportion of foetuses (38%) had no audible foetal heart beat on admission at MNH labour ward and the majority of the neonatal deaths were asphyxiated at delivery. The PMR for multiples and singletons were 269 and 118 respectively resulting in a rate ratio of 2.4 (95%CI: 2.1-2.4). The prevalence of anaemia and severe anaemia was 68% and 5.8%, respectively. Severity of anaemia increased the risk of preterm delivery with ORs of 1.4, 1.4 and 4.1 for women with mild, moderate and severe anaemia as compared to women with normal haemoglobin levels. The corresponding risks for LBW and VLBW were 1.2, 1.7 and 3.8, and 1.5, 1.9 and 4.2 respectively. The prevalence of preterm delivery and LBW was 17% and 14% respectively. The hospital-based incidence of eclampsia was 504 per 10,000 women or 5.1 % of all mothers admitted. Suboptimal care were identified on criteria regarding management plan by senior staff, review of the plans by specialist obstetrician, delay on caesarean section, monitoring patients on magnesium sulphate and inadequate use of the laboratory. Two out of three patients requiring operation were not operated within set standards. Birth asphyxia was the main cause of intrapartum fresh stillbirth (47%) and early neonatal deaths (51%), whereas eclampsia (25%) and preeclampsia (8.3%) were main maternal medical conditions. The majority of stillbirths were fresh, indicating foetal demise during labour or just before delivery. The audit study identified suboptimal care in about 80% of audited cases out of which about 50% were found to be the likely cause of the adverse perinatal outcome. Inadequate maternal and foetal monitoring during labour were the main suboptimal factors, though delay in referral and operative interventions were also prominent. Based on these studies, we conclude that: The perinatal mortality (PMR) in this study was higher than the national average. About one in four perinatal deaths at MNH can be attributed to avoidable factors linked to obstetric care Main causes of perinatal and neonatal deaths were intrapartum birth asphyxia, immaturity related and infections Management of patients in labour needs to be improved Suboptimal care that is essentially avoidable included: inadequate monitoring of patients during labour, delay of care, e.g. long decision to surgery interval, and delayed referral of patients fromprimary hospitals The prevalence of anaemia in pregnancy was very high; and low birth weight and preterm delivery was independently associated with severity of anaemia The prevalence of eclampsia at MNH was high and the case management needs to be improved

- BACKGROUND: Perinatal death is a devastating experience for the mother and of concern in clinical practice. Regular perinatal audit may identify suboptimal care related to perinatal deaths and thus appropriate measures for its reduction. The aim of this study was to perform a qualitative perinatal audit of intrapartum and early neonatal deaths and propose means of reducing the perinatal mortality rate (PMR).METHODS: From 1st August, 2007 to 31st December, 2007 we conducted an audit of perinatal deaths (n = 133) with birth weight 1500 g or more at Muhimbili National Hospital (MNH). The audit was done by three obstetricians, two external and one internal auditors. Each auditor independently evaluated the cases narratives. Suboptimal factors were identified in the antepartum, intrapartum and early neonatal period and classified into three levels of delay (community, infrastructure and health care). The contribution of each suboptimal factor to adverse perinatal outcome was identified and the case graded according to possible avoidability. Degree of agreement between auditors was assessed by the kappa coefficient.RESULTS: The PMR was 92 per 1000 total births. Suboptimal factors were identified in 80% of audited cases and half of suboptimal factors were found to be the likely cause of adverse perinatal outcome and were preventable. Poor foetal heart monitoring during labour was indirectly associated with over 40% of perinatal death. There was a poor to fair agreement between external and internal auditors.CONCLUSION: There are significant areas of care that need improvement. Poor monitoring during labour was a major cause of avoidable perinatal mortality. This type of audit was a good starting point for quality assurance at MNH. Regular perinatal audits to identify avoidable causes of perinatal deaths with feed back to the staff may be a useful strategy to reduce perinatal mortality.

- 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. Methods. 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 >= 11.0 g/dl; mild - Hb 9.0 - 10.9 g/dl; moderate - Hb 7.0 - 8.9 g/dl; and severe - Hb <7.0 g/dl. Logistic regression analysis was performed to estimate the severity of anaemia. The following outcome measures were used: preterm deliver), (<37 weeks), Apgar score, stillbirth, early neonatal death, low birth weight (LBW) (<2 500 g) and very low birth weight (VLBW) (<1 500 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.

- In recent decades, there has been growing attention to the overuse of caesarean section (CS) globally. In light of a high CS rate at a university hospital in Tanzania, we aimed to explore obstetric caregivers' rationales for their hospital's CS rate to identify factors that might cause CS overuse. After participant observations, we performed 22 semi-structured individual in-depth interviews and 2 focus group discussions with 5-6 caregivers in each. Respondents were consultants, specialists, residents, and midwives. The study relied on a framework of naturalistic inquiry and we analyzed data using thematic analysis. As a conceptual framework, we situated our findings in the discussion of how transparency and auditing can induce behavioral change and have unintended effects. Caregivers had divergent opinions on whether the hospital's CS rate was a problem or not, but most thought that there was an overuse of CS. All caregivers rationalized the high CS rate by referring to circumstances outside their control. In private practice, some stated they were affected by the economic compensation for CS, while others argued that unnecessary CSs were due to maternal demand. Residents often missed support from their senior colleagues when making decisions, and felt that midwives pushed them to perform CSs. Many caregivers stated that their fear of blame from colleagues and management in case of poor outcomes made them advocate for, or perform, CSs on doubtful indications. In order to lower CS rates, caregivers must acknowledge their roles as decision-makers, and strive to minimize unnecessary CSs. Although auditing and transparency are important to improve patient safety, they must be used with sensitivity regarding any unintended or counterproductive effects they might have.

- Background: Rising caesarean section (CS) rates have been observed worldwide in recent decades. This study sought to analyse trends in CS rates and outcomes among a variety of obstetric groups at a university hospital in a low-income country. Methods: We conducted a hospital-based panel study at Muhimbili National Hospital, Dar es Salaam, Tanzania. All deliveries between 2000 and 2011 with gestational age >= 28 weeks were included in the study. The 12 years were divided into four periods: 2000 to 2002, 2003 to 2005, 2006 to 2008, and 2009 to 2011. Main outcome measures included CS rate, relative size of obstetric groups, contribution to overall CS rate, perinatal mortality ratio, neonatal distress, and maternal mortality ratio. Time trends were analysed within the ten Robson groups, based on maternal and obstetric characteristics. We applied the chi(2) test for trend to determine whether changes were statistically significant. Odds ratios of CS were evaluated using multivariate logistic regression, accounting for maternal age, referral status, and private healthcare insurance. Results: We included 137,094 deliveries. The total CS rate rose from 19% to 49%, involving nine out of ten groups. Multipara without previous CS with single, cephalic pregnancies in spontaneous labour had a CS rate of 33% in 2009 to 2011. Adjusted analysis explained some of the increase. Perinatal mortality and neonatal distress decreased in multiple pregnancies (p < 0.001 and p = 0.003) and nullipara with breech pregnancies (p < 0.001 and p = 0.024). Although not statistically significant, there was an increase in perinatal mortality (p = 0.381) and neonatal distress (p = 0.171) among multipara with single cephalic pregnancies in spontaneous labour. The maternal mortality ratio increased from 463/100, 000 live births in 2000 to 2002 to 650/100, 000 live births in 2009 to 2011 (p = 0.031). Conclusion: The high CS rate among low-risk groups suggests that many CSs might have been performed on questionable indications. Such a trend may result in even higher CS rates in the future. While CS can improve perinatal outcomes, it does not necessarily do so if performed routinely in low-risk groups.

- BACKGROUND: The maternal near-miss (MNM) concept has been developed to assess life-threatening conditions during pregnancy, childhood, and puerperium. In recent years, caesarean section (CS) rates have increased rapidly in many low- and middle-income countries, a trend which might have serious effects on maternal health. Our aim was to describe the occurrence and panorama of maternal near-miss and death in two low-resource settings, and explore their association with CS complications.METHODS: We performed a cross-sectional study, including all women who fulfilled the WHO criteria for MNM or death between February and June 2012 at a university hospital and a regional hospital in Dar es Salaam, Tanzania. Cases were assessed individually to determine their association with CS. Main outcome measures included MNM ratio; maternal mortality ratio; proportion of MNM and death associated with CS complications; and the risk for such outcomes per 1,000 operations. The risk ratio of life-threatening CS complications at the university hospital compared to the regional hospital was calculated.RESULTS: We identified 467 MNM events and 77 maternal deaths. The MNM ratio was 36 per 1,000 live births (95% CI 33-39) and the maternal mortality ratio was 587 per 100,000 live births (95% CI 460-730). Major causes were eclampsia and postpartum haemorrhage, but we also detected nine MNM events and five deaths from iatrogenic complications. CS complications accounted for 7.9% (95% CI 5.6-11) of the MNM events and 13% (95% CI 6.4-23) of the maternal deaths. The risk of experiencing a life-threatening CS complication was three times higher at the regional hospital (22/1,000 operations, 95% CI 12-37) compared to the university hospital (7.0/1,000 operations, 95% CI 3.8-12) (risk ratio 3.2, 95% CI 1.5-6.6).CONCLUSIONS: The occurrence of MNM and death at the two hospitals was high, and many cases were associated with CS complications. The maternal risks of CS in low-resource settings must not be overlooked, and measures should be taken to avoid unnecessary CSs. More comprehensive training of staff, improved postoperative surveillance, and a more even distribution of resources within the health care system might reduce the risks of CS.

- Objective: To investigate if multiparous individuals who had undergone a previous cesarean delivery experienced an increased risk of severe maternal outcomes or adverse perinatal outcomes compared with multiparous individuals who had undergone previous vaginal deliveries. Methods: An analytical cross-sectional study at a university hospital in Dar es Salaam, Tanzania, enrolled multiparous participants of at least 28 weeks of pregnancy between February 1 and June 30, 2012. Data were collected from patients' medical records and the hospital's obstetric database. Odds ratios (OR) and 95% confidence intervals (Cl) were calculated to compare outcomes among patients who had or had not undergone previous cesarean deliveries. Results: A total of 2478 patients were enrolled. A previous cesarean delivery resulted in no increase in the risk of severe maternal outcomes (OR0.86, 95% CI 0.58-1.26; P = 0.46), and decreased risk of stillbirth (OR 0.42, 95% CI 0.29-0.62, P < 0.001), and intrapartum stillbirth and neonatal distress (OR 0.58, 95% CI 038-0.87, P = 0.007). Conclusion: Previous cesarean delivery was not a risk factor for severe maternal outcomes or adverse perinatal outcomes. The present study was conducted at a referral institution, where individuals with previous cesarean deliveries may constitute a healthy group. Additionally, there could be differences between the study groups in terms of healthcare-seeking behavior, referral mechanisms, intrapartum monitoring, and clinical decision making.

'What about the Mother?' : Rising Caesarean Section Rates and their Association with Maternal Near-Miss Morbidity and Death in a Low-Resource Setting
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In recent decades, there has been a seemingly inexhaustible rise in the use of caesarean section (CS) worldwide. The overall aim with this thesis is to explore the effects of and reasons for an increase in the CS rate at a university hospital in Dar es Salaam, Tanzania.In Study I, we analysed time trends in CS rates and maternal and perinatal outcomes between 2000 and 2011 among different obstetric groups. In Study II, we documented the occurrence and panorama of maternal ‘near-miss’ morbidity and death, and analysed their association with CS complications. We also strived to determine if women with previous CS scars had an increased risk of maternal near-miss, death, or adverse perinatal outcomes in subsequent pregnancies. Studies III and IV explored women’s and caregivers’ in-depth perspectives on CS and caregivers’ rationales for their hospital’s high CS rate.During the study period, the CS rate increased from 19% to 49%. The rise was accompanied by an increased maternal mortality ratio (odds ratio [OR] 1.5, 95% Confidence Interval [CI] 1.2–1.8) and improved perinatal outcomes. CS complications accounted for 7.9% (95% CI 5.6–11) of the maternal near-miss events and 13% (95% CI 6.4–23) of the maternal deaths. Multipara with previous CS scars had no increased risk of maternal near-miss or death compared with multipara with previous vaginal deliveries, and a lower risk of adverse perinatal outcomes (adjusted OR 0.51, 95% CI 0.33–0.80). Both women and caregivers stated they preferred vaginal birth, but caregivers also had a favourable attitude towards CS. Both groups justified maternal risks with CS by the need to ‘secure’ a healthy baby. Caregivers stated that they sometimes performed CSs on doubtful indications, partly due to dysfunctional team-work and a fear of being blamed by colleagues. This thesis raises a concern that maternal health, interests, and voices are overlooked through the CS decision for the benefit of perinatal outcomes and caregivers’ liability. An overuse of CS should be seen as a sign of substandard care and preventing such overuse needs to be among the key actions when formulating new targets for the post-2015 era.
