Substandard emergency obstetric care - a confidential enquiry into maternal deaths at a regional hospital in Tanzania

Objective (i) To identify clinical causes of maternal deaths at a regional hospital in Tanzania and through confidential enquiry (CE) assess major substandard care and make a comparison to the findings of the internal maternal deaths audits (MDAs); (ii) to describe hospital staff reflections on causes of substandard care. Methods A CE into maternal deaths was conducted based on information available from written sources supplemented with participatory observations and interviews with staff. The compiled information was summarized and presented anonymously for external expert review to assess for major substandard care. Hospital based maternal deaths between 2006 and 2008 (35 months) were included. Of 68 registered maternal deaths sufficient information for reviewing was retrieved for 62 cases (91%). As a supplement, in-depth interviews with staff about the underlying causes of substandard care were performed. Results The causes of death were infection (40%), abortion (25%), eclampsia (13%), post-partum haemorrhage (12%), obstructed labour (6%) and others (4%). The median time available for hospital staff to manage the fatal complication was 47 h. The CE identified major substandard care in 46 (74%) of the 62 cases reviewed. During the same time period MDA identified substandard care in 18 cases. Staff perceived poor organization of work and lack of training as important causes for substandard care. Local MDA was considered useful although time-consuming and sometimes threatening, and staff dedication to the process was questioned. Conclusion Quality assurance of emergency obstetric care might be strengthened by supplementing internal MDA with external CE. Soins obstétriques d’urgence de qualité inférieure - enquête confidentielle sur les décès maternels dans un hôpital régional en Tanzanie Objectif: (1) Identifier les causes cliniques de la mortalité maternelle dans un hôpital régional en Tanzanie et au moyen d’une enquête confidentielle (EC), évaluer les soins majeurs de qualité inférieure et comparer ces résultats avec ceux des audits internes des décès maternels (ADM), (2) décrire les réflexions du personnel hospitalier sur les causes de soins de qualité inférieure. Méthodes: Une EC sur les décès maternels a été réalisée sur base des informations disponibles à partir de sources écrites, complétée par des observations de participation et des entretiens avec le personnel. Les informations recueillies ont été résumées et présentées de façon anonyme pour examen par des experts externes afin d’évaluer les soins de qualité inférieure aux normes. Les décès maternels basés à l’hôpital entre 2006 et 2008 (35 mois) ont été inclus. Sur 68 décès maternels enregistrés des informations suffisantes pour l’examen ont été récupérées pour 62 cas (91%). Comme complément, des entretiens approfondis avec le personnel sur les causes sous-jacentes des soins de qualité inférieure ont été réalisées. Résultats: Les causes de décès étaient: infection (40%), avortement (25%), éclampsie (13%), hémorragie post-partum (12%), dystocies (6%) et autres (4%). Le délai médian disponible au personnel hospitalier pour gérer la complication fatale était de 47 heures. L’EC a identifié des soins de qualité inférieure sur 46 (74%) des 62 cas examinés. Pendant la même période les ADM ont identifié des soins de qualité inférieure dans 18 cas. Le personnel a perçu une mauvaise organisation du travail et un manque de formation comme causes importantes des soins de qualité inférieure. Une MDA locale a été jugé utile quoique exigeant en terme de temps et assez intimidant. Le dévouement du personnel au processus a aussi été questionné. Conclusion: L’assurance pour la qualité des soins obstétriques d’urgence pourrait être renforcée en la complétant avec des ADM internes et des EC externes. Cuidados obstétricos de emergencia por debajo del estándar – un análisis confidencial sobre las muertes maternas en un hospital regional de Tanzania Objetivo: (1) Identificar las causas clínicas de las muertes maternas ocurridas en un hospital regional en Tanzania, y mediante entrevistas confidenciales (EC), evaluar cuales son los mayores cuidados subestándar y compararlo con los hallazgos de las auditorías internas de muertes maternas (AMM); (2) describir las reflexiones del personal hospitalario sobre las causas de los cuidados subestándar. Métodos: Las EC de muertes maternas se realizaron basándose en información disponible de fuentes escritas, suplementadas con observaciones y entrevistas al personal sanitario. La información recopilada se resumió y presentó de forma anónima a expertos externos para su revisión con el fin de evaluar los principales cuidados subestándar. Se incluyeron todas las muertes maternas hospitalarias acaecidas entre 2006 y 2008 (35 meses). De 68 muertes maternas registradas había suficiente información para recuperar 62 casos (91%). Adicionalmente se realizaron entrevistas a fondo con el personal sanitario sobre las causas subyacentes de cuidados subestándar. Resultados: Las causas de muerte fueron infección (40%), aborto (25%), eclampsia (13%), hemorragia post parto (12%), parto obstruido (6%) y otros (4%). El tiempo medio disponible para que el equipo sanitario manejase una complicación fatal era de 47 horas. La EC identificó cuidados subestándar mayores en 18 casos. El equipo sanitario percibía la mala organización del trabajo y la falta de entrenamiento como causas importantes de cuidados subestándar. La AMM local se consideraba como útil aunque se percibía que consumía mucho tiempo y a veces era descrita como “amenazadora”, y se cuestionaba la dedicación del equipo médico al proceso. Conclusión: El control de calidad de EmOC podría fortalecerse mediante la suplementación de los AMM internos con EC externos. The 5th of the eight Millennium Development Goals (MDG 5) declared by the United Nations is a 75% reduction in maternal deaths from 1990 to 2015 (United Nations 2000). The global progress towards MDG 5 is minimal, especially in sub-Saharan Africa, where the problem is most severe (Hill et al. 2007; Bryce et al. 2008). The main strategy to reach MDG 5 has been to have a ‘skilled birth attendant’ (SBA) at 90% of all births (World Health Organization 2005). However, a review of ecological and observational studies in developing countries concludes that there is ‘little evidence that giving birth with a health professional reduces the risk of dying, and in some settings it appears to be associated with an increased risk of dying’ (Scott (ii) delays in transport; (iii) delays within the health facilities. If health facility delays are a major contributing factor to maternal deaths they must be reduced to an acceptable level before the other delays are addressed (Thaddeus written information was retrieved from hospital statistics, case records, hospital registration books and local MDA forms. Participatory observations and interviews with staff contributed additional information. The compiled information was summarized and presented as cases in an anonymous form for external expert review to assess for substandard care. As a supplement to the case-specific CE, in-depth interviews with staff about the causes of delays in care in general were conducted. The study took place in Tanzania at a regional hospital providing comprehensive EmOC. MDA was initiated in January 2006 and a consultant in obstetrics and gynaecology was appointed as medical officer in charge of the hospital in December 2007. One hundred and eight maternal deaths were registered at the regional hospital between 2004 and 2008. The CE was performed for all registered maternal deaths at the hospital from January 2006 to November 2008 (35 months), the same period during which MDAs had been carried out. In all, 68 maternal deaths had been registered and sufficient written information for reviewing was retrieved from 62 (91%) cases (47 from case files and 15 from the ‘hospital registration book’). These 62 cases were included in the CE. According to the Regional Medical Officer’s statistics, only two maternal deaths at peripheral health facilities referring to the study site were registered during the study period and no community based maternal deaths. Data were collected during the periods July–November 2007 and July–November 2008. An exploratory approach with the intention to exhaust all available data sources related to each case was applied. Data sources were: (i) written documentation from registers and case files supplemented by (ii) participatory observations, and (iii) interviews with staff. The case files for registered maternal deaths and the ‘hospital registration book’ were reviewed and detailed notes were made. For supplementary information, MDA reports and registration books from the operating theatre and labour ward were reviewed. Not included were six maternal deaths with insufficient or no written documentation about management (four cases of maternal death from infection and two from eclampsia). Normal deliveries at the labour ward for 4 weeks in August 2007 were observed. During this period and on two other occasions, six cases of maternal deaths were observed. Interviews with staff about clinical management were carried out and added minor information to 27 (44%) cases. As a supplement to the case-specific data collection, semi-structured in-depth interviews about causes in general for substandard care were performed with nine staff representing different professions: three health administrators (HA), three nurse-midwives (NM) and three assistant medical officers (AMO). AMOs have 4 years of pre-graduate training and are responsible for clinical management and surgery in the absence of medical doctors (MD). The interviews lasted from 20 to 45 min, six were recorded and transcribed and notes were written while being conducted. From the available information, the cases of maternal deaths were reviewed. Based on the material, the main clinical causes of death could be categorized under the following: ‘infections’, ‘complications from abortions’, ‘post-partum haemorrhage’ (PPH), ‘pregnancy-induced hypertension’ (PIH), ‘obstructed labour’ and ‘others’ and were listed by frequency (Table 2). The time available to provide EmOC at the hospital was estimated. If the patient arrived at the hospital with the complication, the ‘time to provide EmOC’ was the time from admission to death. Each maternal death was described as thoroughly as possible from the retrieved information and assessed by three external Tanzanian reviewers, all consultants in obstetrics and gynaecology. For each case the reviewers assessed if there was major substandard care involved, in other words, whether the maternal death could have been avoided without the delay. Answer options were ‘yes’, ‘no’ or ‘in doubt’. Each reviewer assessed the cases individually with the possibility of discussing cases or asking questions if clarification was required. If two or three reviewers had answered ‘yes’ the case was judged as involving a ‘significant’ delay. The in-depth interviews with staff about their reflections on causes in general for substandard care were analyzed separately. By reading through the interview transcripts the following main themes were identified: ‘organization of work’, ‘training’ and ‘maternal death was a major to maintain anonymity of the staff and others in the maternal deaths that were reviewed. were presented to reviewers in a where the health and the could not be The study had from the of Medical Research in was from the of Medical Research and from of Health and Tanzania as as from the Medical One hundred and eight maternal deaths were registered between 2004 and 2008.
