Evaluation of a traditional birth attendant training programme in Bangladesh

Background and context

the 1997 Safe Motherhood Initiative effectively eliminated support for training traditional birth attendants (TBAs) in safe childbirth. Despite this, TBAs are still active in many countries such as Bangladesh, where 88% of deliveries occur at home. Renewed interest in community-based approaches and the urgent need to improve birth care has necessitated a re-examination of how provider training should be conducted and evaluated.

Objective

to demonstrate how a simple evaluation tool can provide a quantitative measure of knowledge acquisition and intended behaviour following a TBA training program.

Design

background data were collected from 45 TBAs attending two separate training sessions conducted by Bangladeshi non-governmental organization (NGO) Gonoshasthaya Kendra (GK). A semi-structured survey was conducted before and after each training session to assess the TBAs’ knowledge and reported practices related to home-based management of childbirth.

Setting

two training sessions conducted in Vatshala and Sreepur in rural Bangladesh.

Participants

45 active TBAs were recruited for this training evaluation.

Findings

there were significant improvements following the training sessions regarding how TBAs reported they would: (a) measure blood loss, (b) handle an apneic newborn, (c) refer women with convulsions and (d) refer women who are bleeding heavily. A greater degree of improvement, and higher scores overall, were observed among TBAs with no prior training and with less birth experience.

Key conclusions and recommendations for practice

as the Safe Motherhood community strives to improve safe childbirth care, the quality of care in pregnancy and childbirth for women who rely on less-skilled providers should not be ignored. These communities need assistance from governments and NGOs to help improve the knowledge and skill levels of the providers upon which they depend. Gonoshasthaya Kendra's extensive efforts to train and involve TBAs, with the aim of improving the quality of care provided to Bangladeshi women, is a good example of how to effectively integrate TBAs into safe motherhood efforts in resource-poor settings. The evaluation methodology described in this paper demonstrates how trainees’ prior experiences and beliefs may affect knowledge acquisition, and highlights the need for more attention to course content and pedagogic style.     

Patient safety and communication: A new assessment for doctors trained in countries where language differs from that of the host country: Results of a pilot using a domain-based assessment

Objective

Global migration of healthcare workers places responsibility on employers to comply with legal employment rights whilst ensuring patient safety remains the central goal. We describe the pilot of a communication assessment designed for doctors who trained and communicated with patients and colleagues in a different language from that of the host country. It is unique in assessing clinical communication without assessing knowledge.

Methods

A 14-station OSCE was developed using a domain-based marking scheme, covering professional communication and English language skills (speaking, listening, reading and writing) in routine, acute and emotionally challenging contexts, with patients, carers and healthcare teams. Candidates (n = 43), non-UK trained volunteers applying to the UK Foundation Programme, were provided with relevant station information prior to the exam.

Results

The criteria for passing the test included achieving the pass score and passing 10 or more of the 14 stations. Of the 43 candidates, nine failed on the station criteria. Two failed the pass score and also the station criteria. The Cronbach's alpha coefficient was 0.866.

Conclusion

This pilot tested ‘proof of concept’ of a new domain-based communication assessment for non-UK trained doctors.

Practice implications

The test would enable employers and regulators to verify communication competence and safety in clinical contexts, independent of clinical knowledge, for doctors who trained in a language different from that of the host country.     

A novel region-based level set method initialized with mean shift clustering for automated medical image segmentation

Appropriate initialization and stable evolution are desirable criteria to satisfy in level set methods. In this study, a novel region-based level set method utilizing both global and local image information complementarily is proposed. The global image information is extracted from mean shift clustering without any prior knowledge. Appropriate initial contours are obtained by regulating the clustering results. The local image information, as extracted by a data fitting energy, is employed to maintain a stable evolution of the zero level set curves. The advantages of the proposed method are as follows. First, the controlling parameters of the evolution can be easily estimated by the clustering results. Second, the automaticity of the model increases because of a reduction in computational cost and manual intervention. Experimental results confirm the efficiency and accuracy of the proposed method for medical image segmentation.     

COVID-19: A pluralistic and integrated approach for efficient management of the pandemic

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which triggered the ongoing pandemic, was first discovered in China in late 2019. SARS-CoV-2 is a respiratory virus responsible for coronavirus disease 2019 (COVID-19) that often manifests as a pneumonic syndrome. In the context of the pandemic, there are mixed views on the data provided by epidemiologists and the information collected by hospital clinicians about their patients. In addition, the literature reports a large proportion of patients free of pneumonia vs a small percentage of patients with severe pneumonia among confirmed COVID-19 cases. This raises the issue of the complexity of the work required to control or contain the pandemic. We believe that an integrative and pluralistic approach will help to put the analyses into perspective and reinforce collaboration and creativity in the fight against this major scourge. This paper proposes a comprehensive and integrative approach to COVID-19 research, prevention, control, and treatment to better address the pandemic. Thus, this literature review applies a pluralistic approach to fight the pandemic.     

Global prevalence of latent toxoplasmosis in pregnant women: a systematic review and meta-analysis

BackgroundToxoplasma gondii infection, if acquired as an acute infection during pregnancy, can have substantial adverse effects on mothers, fetuses and newborns. Latent toxoplasmosis also causes a variety of pathologies and has been linked to adverse effects on pregnancy.ObjectiveHere, we present results of a comprehensive systematic review and meta-analysis of the global prevalence of latent toxoplasmosis in pregnant women.Data sourceWe searched PubMed, EMBASE, Web of Science, SciELO and Scopus databases for relevant studies that were published between 1 January 1988 and 20 July 2019.Study eligibility criteriaAll population-based, cross-sectional and longitudinal studies reporting the prevalence of latent toxoplasmosis in healthy pregnant women were considered for inclusion.ParticipantsPregnant women who were tested for prevalence of latent toxoplasmosis.InterventionsThere were no interventions.MethodWe used a random effects model to calculate pooled prevalence estimates with 95% confidence intervals (CIs). We grouped prevalence data according to the geographic regions defined by the World Health Organization (WHO). Multiple subgroup and meta-regression analyses were performed.ResultsIn total, 311 studies with 320 relevant data sets representing 1 148 677 pregnant women from 91 countries were eligible for inclusion in the meta-analysis. The global prevalence of latent toxoplasmosis in pregnant women was estimated at 33.8% (95% CI, 31.8–35.9%; 345 870/1 148 677). South America had the highest pooled prevalence (56.2%; 50.5–62.8%) of latent toxoplasmosis in pregnant women, whereas the Western Pacific region had the lowest prevalence (11.8%; 8.1–16.0%). A significantly higher prevalence of latent toxoplasmosis was associated with countries with low income and low human development indices (p < 0.001).ConclusionOur results indicate a high level of latent toxoplasmosis in pregnant women, especially in some low- and middle-income countries of Africa and South America, although the local prevalence varied markedly. These results suggest a need for improved prevention and control efforts to reduce the health risks to women and newborns.

Don't let the suffering make you fade away: An ethnographic study of resilience among survivors of genocide-rape in southern Rwanda

Rape has been used in contemporary armed conflicts to inflict physical, psychological, cultural and social damage. In endeavoring to address the psychological damage of collective violence, some researchers and global health practitioners are turning toward post-conflict mental health promotion approaches that centrally feature resilience. Though previous findings from resilience and coping research are robust, few studies have actually investigated resilience among genocide-rape survivors in cultural context in non-Western settings. This paper presents ethnographic data gathered over 14 months (September 2005 to November 2006) in southern Rwanda on resilience among genocide-rape survivors who were members of two women's genocide survivor associations. Study methods included a content analysis of a stratified purposive sample of 44 semi-structured interviews, as well as participant-, and non-participant-observation. Resilience among genocide-rape survivors in this context was found to be shaped by the cultural-linguistic specific concepts of kwihangana (withstanding), kwongera kubaho (living again), and gukomeza ubuzima (continuing life/health), and comprised of multiple sociocultural processes that enabled ongoing social connection with like others in order to make meaning, establish normalcy, and endure suffering in daily life. The results of this research show that the process of resilience among genocide-rape survivors was the same regardless of whether genocide survivor association membership was organized around the identity of genocide-rape survivorship or the identity of widowhood. However, the genocide-rape survivors' association members were more involved with directing resilience specifically toward addressing problems associated with genocide-rape compared to the members of the genocide widows' association. The findings from this research suggest that ethnographic methods can be employed to support resilience-based post-conflict mental health promotion efforts through facilitating collective sexual violence survivors to safely socially connect around their shared experiences of rape, neutralizing social threats of stigma and marginalization.
