[PMID: 38024895 PMCID: PMC10657104 DOI: 10.4103/jfmpc.jfmpc_178_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 06/08/2023] [Accepted: 06/09/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction As per WHO guidelines, it is important to have quality among mortality audit documents to improve outcome in health services. Objective To assess quality of facility-based neonatal mortality audits implementation. Methodology Mixed-method descriptive analysis was conducted. Totally, 96 death review documents were reviewed. The 25 healthcare workers were interviewed in depth. Observation analysis done for audit meetings using WHO modified checklist for quality in audit toolkit. Results The observation of audit meetings highlighted that almost half of the members were not communicated regarding vision of audit and framework of audit and review meetings. In quantitative analysis, it was found that secondary care hospitals were not having accuracy and consistency in audit documentation. Conclusion The quality of neonatal death audit was poor due to challenges faced by the hospitals in creating an enabling atmosphere, which can be overcome by sharing the vision of audit with the whole staff of the hospital. A standard operating procedure for audit committee to be adopted to implement action plans. Commitment, investment, and intentional leadership from everyone, including all healthcare workers, can make these ambitious goals attainable.

EClinicalMedicine 2023; 59:101976. [PMID: 37180470 PMCID: PMC10173150 DOI: 10.1016/j.eclinm.2023.101976] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 04/05/2023] [Accepted: 04/06/2023] [Indexed: 05/16/2023] Open
Abstract
Background Facility-based stillbirth review provides opportunities to estimate incidence, evaluate causes and risk factors for stillbirths, and identify any issues related to the quality of pregnancy and childbirth care which require improvement. Our aim was to systematically review all types and methods of facility-based stillbirth review processes used in different countries across the world, to examine how stillbirth reviews in facility settings are being conducted worldwide and to identify the outcomes of implementing the reviews. Moreover, to identify facilitators and barriers influencing the implementation of the identified facility-based stillbirth reviews processes by conducting subgroup analyses. Methods A systematic review of published literature was conducted by searching MEDLINE (OvidSP) [1946-present], EMBASE (OvidSP) [1974-present], WHO Global Index Medicus (globalindexmedicus.net), Global Health (OvidSP) [1973-2022 Week 8] and CINAHL (EBSCOHost) [1982-present] from their inception until 11 January, 2023. For unpublished or grey literature, the WHO databases, Google Scholar and ProQuest Dissertations & Theses Global were searched, as well as hand searching the reference lists of included studies. MESH terms encompassing "∗Clinical Audit", "∗Perinatal Mortality", "Pregnancy Complications", and "Stillbirth" were used with Boolean operators. Studies that used a facility-based review process or any approach to evaluate care prior to stillbirth, and explained the methods used were included. Reviews and editorials were excluded. Three authors (YYB, UGA, and DBT) independently screened and extracted data, and assessed the risk of bias using an adapted JBI's Checklist for Case Series. A logic model was used to inform the narrative synthesis. The review protocol was registered with PROSPERO, CRD42022304239. Findings A total of 68 studies from 17 high-income (HICs) and 22 low-and-middle-income countries (LMICs) met the inclusion criteria from a total of 7258 identified records. These were stillbirth reviews conducted at different levels: district, state, national, and international. Three types were identified: audit, review, and confidential enquiry, but not all desired components were included in most processes, which led to a mismatch between the description of the type and the actual method used. Routine data from hospital records was the most common data source for identifying stillbirths, and case assessment was based on stillbirth definition in 48 out of 68 studies. Hospital notes were the most common source of information about care received and causes/risk factors for stillbirth. Short-term and medium-term outcomes were reported in 14 studies, but impact of the review process on reducing stillbirth, which is more difficult to establish, was not reported in any study. Facilitators and barriers in implementing a successful stillbirth review process identified from 14 studies focused on three main themes: resources, expertise, and commitment. Interpretation This systematic review's findings identified that there is a need for clear guidelines on how to measure the impact of implementation of changes based on outputs of stillbirth reviews and methods to enable effective dissemination of learning points in the future and promoting them through training platforms. In addition, there is a need to develop and adopt a universal definition of stillbirth to facilitate meaningful comparison of stillbirth rates between regions. The key limitation of this review is that while using a logic model for narrative synthesis was deemed most appropriate for this study, sequence of implementing a stillbirth review in the real world is not linear, and assumptions are often not met. Therefore, the logic model proposed in this study should be interpreted with flexibility when designing a stillbirth review process. The generated learnings from the stillbirth review processes inform the action plans and allow facilities to consider where the changes should happen to improve the quality of care in the facilities, enabling positive short-term and medium-term outcomes.

Abstract
BACKGROUND Stillbirth rates have shown little improvement for two decades in Australia. Perinatal mortality audit is key to prevention, but the literature suggests that implementation is suboptimal. AIM To determine the proportion of perinatal deaths which are associated with contributing factors relating to care in Queensland, Australia. MATERIALS AND METHODS Retrospective audit of perinatal deaths ≥ 34 weeks gestation by the Health Department in Queensland was undertaken. Cases and demographic information were obtained from the Queensland Perinatal Data Collection. A multidisciplinary panel used the Perinatal Society of Australia and New Zealand (PSANZ) perinatal mortality audit guidelines to classify the cause of death and to identify contributing factors. Contributing factors were classified as 'insignificant', 'possible', or 'significant'. RESULTS From 1 January to 31 December 2018, 65 deaths (56 stillbirths and nine neonatal deaths) were eligible and audited. Most deaths were classified as unexplained (51.8% of stillbirths). Contributing factors were identified in 46 (71%) deaths: six insignificant (all stillbirths), 20 possibly related to outcome (17 stillbirths), and 20 significantly (16 stillbirths). Areas for practice improvements mainly related to the care for women with risk factors for stillbirth, especially antenatal care. The PSANZ guidelines were applied and enabled a systematic approach. CONCLUSIONS A high proportion of late gestation perinatal deaths are associated with contributing factors relating to care. Improving antenatal care for women with risk factors for stillbirth is a priority. Perinatal mortality audit is a valuable step in stillbirth prevention and the PSANZ guidelines allow a systematic approach to aid implementation and reporting.

BMJ Open Qual 2021; 10:e001266. [PMID: 33722879 PMCID: PMC7970257 DOI: 10.1136/bmjoq-2020-001266] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 02/22/2021] [Accepted: 03/04/2021] [Indexed: 11/04/2022] Open
Abstract
PURPOSE To identify approaches, enablers, barriers and outcomes of facility stillbirth and neonatal death audit in low-income and middle-income countries (LMICs). DATA SOURCES We searched MEDLINE, CINAHL Complete, Academic Search Index, Science Citation Index, Complementary index and Global health electronic databases. STUDY SELECTION Studies were considered eligible when reporting the approaches, enablers, barriers and outcomes of facility-based stillbirth and neonatal death audit in LMICs. DATA EXTRACTION Two authors independently performed the data extraction using predefined templates made before data extraction. RESULTS OF DATA SYNTHESIS A total of 10 articles from 7 countries were included in the final analysis. Facility or external multidisciplinary teams performed death audits on a weekly or monthly basis. A total of 1018 stillbirths and neonatal deaths were audited. Of 18 audit enablers identified, nine were at the health provider level while 18 of 23 barriers to audit that were identified occurred at the facility level. The facility-level barriers cited by more than one study included: failure to implement change; inadequate training; limited time; increased workload; too many cases and poor documentation. Six studies reported that death audits resulted in structural improvements in physical structure, training, service organisation, supplies and equipment in the wards. Five studies reported that death audits improved the standard of care, with one study showing a significant improvement in measured standards. One study reported a significant reduction in newborn mortality rate of 29.4% (95% CI 0.6% to 2.4%; p=0.0015) and one study a reduction in perinatal mortality of 4.9% (52.8% in 2007 to 47.9% in 2008) before and after perinatal audit implementation. CONCLUSION Stillbirth and neonatal death audit improves facility structures, processes of care and health outcomes in neonatal care. There is a need to enhance enablers and address barriers identified at both health provider and facility levels to improve the audit process.

Abstract
Background and Objectives: The number of stillbirths has reduced more slowly than has maternal mortality or mortality in children younger than 5 years, which were explicitly targeted in the Millennium Development Goals. Placental pathologies and infection associated with preterm birth are linked to a substantial proportion of stillbirths. Appropriate preconception care and quality antenatal care that is accessible to all women has the potential to reduce stillbirth rates. The aim of the present study was to assess potential risk factors associated with stillbirth within maternal medical diseases and obstetric complications. Materials and Methods: Retrospective cohort study (2001-2014) was used to analyse data from the Medical Birth Register on stillbirth and live births as controls. Adjusted Odds ratios (aOR) with 95% confidence intervals (CI) were estimated. Multiple regression model adjusted for maternal age, parity and gestational age. Results: The stillbirth rate was 6.2 per 1000 live and stillbirths. The presence of maternal medical diseases greatly increased the risk of stillbirth including diabetes mellitus (aOR = 2.5; p < 0.001), chronic hypertension 3.1 (aOR = 3.1; p < 0.001) and oligohydromnios/polyhydromnios (aOR = 2.4; p < 0.001). Pregnancy complications such as intrauterine growth restriction (aOR = 2.2; p < 0.001) was important risk factor for stillbirth. Abruption was associated with a 2.8 odds of stillbirth. Conclusions: Risk factors most significantly associated with stillbirth include maternal history of chronic hypertension and abruptio placenta which is a common cause of death in stillbirth. Early identification of potential risk factors and appropriate perinatal management are important issues in the prevention of adverse fetal outcomes and preventive strategies need to focus on improving antenatal detection of fetal growth restriction.

Abstract
INTRODUCTION Stillbirth is one of the most common adverse pregnancy outcomes worldwide. Late foetal death (LFD) rates are mostly used for international comparisons because of the large variations in stillbirth rates between countries. OBJECTIVE To examine trends in LFD (including antepartum and intrapartum) by multiple births, birth weight, and maternal age in two time periods. METHODS A retrospective cohort study was used to analyse data from the Medical Birth Register (2001-2014), divided into 2 periods of 7 years each. In total, data on 1,340 singletons were analysed. This study calculated LFD rates and rate ratios (RR). RESULTS The overall LFD rate showed a slight statistically significant reduction (p < 0.001) of 18% between 2001-2007 and 2008-2014. There was a slight increase in the mortality rate from multiple pregnancies (RR 1.1/1000; 95% CI 0.6-1.9). There were no major differences in the LFD rate by maternal age during the time periods. CONCLUSIONS LFD decreased (RR 0.8/1000 births), as well as intrapartum LFD (RR 0.6/1000 births). Older maternal age influenced pregnancy outcomes, and higher LFD rates were observed in the age group ≥35 years. Substantial intrapartum stillbirths rates indicate problems with quality of intrapartum care and emergency obstetric care. Further research is needed to evaluate the strategies necessary to substantially reduce the number of stillbirths in the country.

Abstract
Resumo Avaliou-se a adequação da investigação do óbito infantil no Recife-PE, Brasil. Estudo transversal com 120 variáveis da ficha de investigação, agrupadas em seis dimensões (pré-natal; parto e nascimento; puericultura; características da família; ocorrência do óbito; e conclusão e recomendações), ponderadas pela técnica de consenso e analisadas quanto ao preenchimento. A investigação foi classificada (adequada, parcialmente adequada e inadequada) segundo um indicador composto de avaliação (ICA). Houve dissenso em 11 variáveis (9, na dimensão pré-natal; 1, no parto e nascimento; 1, na conclusões e recomendações). Dos 568 óbitos estudados, 56,2% apresentam investigação adequada. A ocorrência do óbito foi a dimensão melhor avaliada, e pré-natal, a mais deficiente. A elaboração do ICA possibilita aos profissionais e gestores das políticas de saúde da criança, identificar os pontos de estrangulamento da investigação dos óbitos infantis para um melhor direcionamento das ações e contribui com a reflexão sobre esta vigilância em outros municípios e estados.

Abstract
Abstract Objectives: assess the implementation of child mortality surveillance in Recife/PE. Methods: an analytical evaluative study was conducted on its implementation. It was a single-case study that correlated degree of implementation with the of the result indicators surveillance. A logic model on this strategy and a matrix of indicators and judgments according to model components were drawn up. The degree of implementation was obtained from structure and process indicators and this was then correlated with result indicators, in a deductive approach based on intervention theory. Results: the structure approach presented superior results to the process in all evaluated components. This strategy was considered to have been partially implemented (75. 7%), however, the components of 'identification of deaths' (85.7%), 'epidemiological research' (88.1%) and 'referral of proposals for promotion and health care and correction of official statistics' (95.8%) were classified implemented. Regarding the relation of the degree of implantation of the surveillance and its results with the logical model, only one of the 17 indicators was considered inconsistent. Conclusions: this strategy was considered to have been partially implemented. The model of child mortality surveillance and its assessment were shown to be adequate for signaling the consistency of the interrelations between the activities proposed and the effects expected, and would be reproducible within other scenarios.

Abstract
Accurate and consistent classification of causes and associated conditions for perinatal deaths is essential to inform strategies to reduce the five million which occur globally each year. With the majority of deaths occurring in low- and middle-income countries (LMICs), their needs must be prioritised. The aim of this paper is to review the classification of perinatal death, the contemporary classification systems including the World Health Organization's International Classification of Diseases - Perinatal Mortality (ICD-PM), and next steps. During the period from 2009 to 2014, a total of 81 new or modified classification systems were identified with the majority developed in high-income countries (HICs). Structure, definitions and rules and therefore data on causes vary widely and implementation is suboptimal. Whereas system testing is limited, none appears ideal. Several systems result in a high proportion of unexplained stillbirths, prompting HICs to use more detailed systems that require data unavailable in low-income countries. Some systems appear to perform well across these different settings. ICD-PM addresses some shortcomings of ICD-10 for perinatal deaths, but important limitations remain, especially for stillbirths. A global approach to classification is needed and seems feasible. The new ICD-PM system is an important step forward and improvements will be enhanced by wide-scale use and evaluation. Implementation requires national-level support and dedicated resources. Future research should focus on implementation strategies and evaluation methods, defining placental pathologies, and ways to engage parents in the process.

Abstract
Each year, the Board of Directors of the Society for Obstetric Anesthesia and Perinatology selects an individual to review a given year's published obstetric anesthesiology literature. This individual then produces a syllabus of the year's most influential publications, delivers the Ostheimer Lecture at the Society's annual meeting, the Hughes Lecture at the following year's Sol Shnider meeting, and writes corresponding review articles. This 2016 Hughes Lecture review article focuses specifically on the 2014 publications that relate to maternal morbidity and mortality. It begins by discussing the 2014 research that was published on severe maternal morbidity and maternal mortality in developed countries. This is followed by a discussion of specific coexisting diseases and specific causes of severe maternal mortality. The review ends with a discussion of worldwide maternal mortality and the 2014 publications that examined the successes and the shortfalls in the work to make childbirth safe for women throughout the entire world.

Secretory Aspartyl Proteinases Cause Vaginitis and Can Mediate Vaginitis Caused by Candida albicans in Mice. mBio 2015; 6:e00724.

Abstract
UNLABELLED Vaginal inflammation (vaginitis) is the most common disease caused by the human-pathogenic fungus Candida albicans. Secretory aspartyl proteinases (Sap) are major virulence traits of C. albicans that have been suggested to play a role in vaginitis. To dissect the mechanisms by which Sap play this role, Sap2, a dominantly expressed member of the Sap family and a putative constituent of an anti-Candida vaccine, was used. Injection of full-length Sap2 into the mouse vagina caused local neutrophil influx and accumulation of the inflammasome-dependent interleukin-1β (IL-1β) but not of inflammasome-independent tumor necrosis factor alpha. Sap2 could be replaced by other Sap, while no inflammation was induced by the vaccine antigen, the N-terminal-truncated, enzymatically inactive tSap2. Anti-Sap2 antibodies, in particular Fab from a human combinatorial antibody library, inhibited or abolished the inflammatory response, provided the antibodies were able, like the Sap inhibitor Pepstatin A, to inhibit Sap enzyme activity. The same antibodies and Pepstatin A also inhibited neutrophil influx and cytokine production stimulated by C. albicans intravaginal injection, and a mutant strain lacking SAP1, SAP2, and SAP3 was unable to cause vaginal inflammation. Sap2 induced expression of activated caspase-1 in murine and human vaginal epithelial cells. Caspase-1 inhibition downregulated IL-1β and IL-18 production by vaginal epithelial cells, and blockade of the IL-1β receptor strongly reduced neutrophil influx. Overall, the data suggest that some Sap, particularly Sap2, are proinflammatory proteins in vivo and can mediate the inflammasome-dependent, acute inflammatory response of vaginal epithelial cells to C. albicans. These findings support the notion that vaccine-induced or passively administered anti-Sap antibodies could contribute to control vaginitis. IMPORTANCE Candidal vaginitis is an acute inflammatory disease that affects many women of fertile age, with no definitive cure and, in its recurrent forms, causing true devastation of quality of life. Unraveling the fungal factors causing inflammation is important to be able to devise novel tools to fight the disease. In an experimental murine model, we have discovered that aspartyl proteinases, particularly Sap2, may cause the same inflammatory signs of vaginitis caused by the fungus and that anti-Sap antibodies and the protease inhibitor Pepstatin A almost equally inhibit Sap- and C. albicans-induced inflammation. Sap-induced vaginitis is an early event during vaginal infection, is uncoupled from fungal growth, and requires Sap and caspase-1 enzymatic activities to occur, suggesting that Sap or products of Sap activity activate an inflammasome sensor of epithelial cells. Our data support the notion that anti-Sap antibodies could help control the essence of candidal vaginitis, i.e., the inflammatory response.
