Background: Reducing avoidable healthcare-associated harm is a global health priority. Progress in evaluating the burden and aetiology of avoidable harm in prisons is limited compared with other healthcare sectors. To address this gap, this study aimed to develop a definition of avoidable harm to facilitate future epidemiological studies in prisons. Methods: Using a sequential mixed methods study design we first characterised and reached consensus on the types and avoidability of patient harm in prison healthcare involving analysis of 151 serious prison incidents reported to the Strategic Executive Information System (StEIS) followed by in-depth nominal group (NG) discussions with four former service users and four prison professionals. Findings of the NG discussions and StEIS analysis were then synthesised and discussed among the research team and study oversight groups to develop an operational definition of avoidable harm in prison healthcare which was subsequently tested and validated using prison patient safety incident report data derived from the National Reporting and Learning System (NRLS). Results: Analysis of StEIS incident reports and NG discussions identified important factors influencing avoidable harm which reflected the unique prison setting, including health care delivery issues and constraints associated with the secure environment which limited access to care. These findings informed the development of a new working two-tier definition of avoidable harm using appropriate and timely intervention, which included an additional assessment of harm avoidability taking into the account the prison regime and environment. The definition was compatible with the NRLS incident report narratives and illustrated how the prison environment may influence identification of avoidable harm and judgements of avoidability. Conclusions: We have developed a working definition of avoidable harm in prison health care that enables consideration of caveats associated with prison environments and systems. Our definition enables future studies of the safety of prison healthcare to standardise outcome measurement. [ABSTRACT FROM AUTHOR]

Compared to other species, the extent of human cooperation is unparalleled. Such cooperation is coordinated between community members via social norms. Developmental research has demonstrated that very young children are sensitive to social norms, and that social norms are internalized by middle childhood. Most research on social norm acquisition has focused on norms that modulated intra-group cooperation. Yet around the world, multi-ethnic communities also cooperate, and this cooperation is often shaped by distinct inter-group social norms. In the present study, we will investigate whether inter-ethnic and intra-ethnic social norm acquisition follows the same, or distinct, developmental trajectories. Specifically, we will work with BaYaka foragers and Bandongo fisher-farmers who inhabit multi-ethnic villages in the Republic of the Congo. In these villages, inter-ethnic cooperation is regulated by sharing norms. Through interviews with adult participants, we will provide the first descriptive account of the timing and mechanism by which BaYaka and Bandongo learn to share with out-group members. Children (5–17 years) and adults (17+ years) will also participate in a modified Dictator Game to investigate the developmental trajectories of children's intra- and inter-ethnic sharing choices. Based on our ethnographic knowledge of the participating communities, we predict that children's intra-ethnic sharing choices in the Dictator Game will match those of adults at an earlier age than their inter-ethnic sharing choices. We will analyze our data using logistic Bayesian modelling. [ABSTRACT FROM AUTHOR]

While all lower limb prosthesis walkers have a high risk of tripping and/or falling, above knee prosthesis users are reported to fall more frequently. Recognising this, engineers designed microprocessor knees (MPK) to help mitigate these risks, but to what extent these devices reduce this disparity between above and below knee users is unclear. A service review was carried out in a prosthetic limb centre regarding the frequency of trips and falls in the previous four weeks. Data from unilateral, community ambulators were extracted. Ordered logistic regressions were applied to investigate whether MPKs mitigated the increased risk of trips and falls for prosthetic knee users, compared to below knee prosthesis users. Socio-demographics (sex, age), prosthesis (prosthesis type, years of use), health (comorbidities, vision, contralateral limb status, medication), and physical function (use of additional walking aids, activity level) were included as covariates. Of the 315 participants in the analysis, 57.5% reported tripping and 20.3% reported falling. Non-microprocessor prosthetic knee (non-MPK) users were shown to trip significantly more than below knee prosthesis users (OR = 1.96, 95% CI = 1.17–3.28). Other covariates showing a significant association included contralateral limb injuries (OR = 1.91, 95% CI = 1.15–3.18) and using an additional walking aid (OR = 1.99, 95% CI = 1.13–3.50). Non-MPK users were also shown to fall significantly more than below knee prosthesis users (OR = 3.34, 95% CI = 1.73–6.45), with no other covariates showing a significant association. MPK users did not show an increased frequency of trips (OR = 0.74, 95% CI = 0.33–1.64) or falls (OR = 0.34, 95% CI = 0.18–2.62), compared to below knee prosthesis users. Of those who tripped at least once in the previous four weeks, those using a non-MPK (OR = 2.73, 95% CI = 1.30–5.74) presented an increased frequency of falling. These findings provide evidence to suggest that the use of MPKs reduces the difference in falls risk between above knee and below knee prosthesis users, providing justification for their provision.

Background: Prevalence of accessing antenatal care (ANC) services among Indigenous women in the Chittagong Hill Tracts (CHT) is unknown. This study aims to estimate the prevalence of accessing ANC services by Indigenous women in the CHT and identify factors associated with knowledge of, and attendance at, ANC services. Methods: Using a cross-sectional design three Indigenous groups in Khagrachari district, CHT, Bangladesh were surveyed between September 2017 and February 2018. Indigenous women within 36 months of delivery were asked about attending ANC services and the number who attended was used to estimate prevalence. Socio-demographic and obstetric characteristics were used to determine factors associated with knowledge and attendance using multivariable logistic regression techniques adjusted for clustering by village; results are presented as odds ratios (OR), adjusted OR, and 95% confidence intervals (CI). Results: Of 494 indigenous women who met the inclusion criteria in two upazilas, 438 participated (89% response rate) in the study, 75% were aged 16–29 years. Sixty-nine percent were aware of ANC services and the prevalence of attending ANC services was 53% (n = 232, 95%CI 0.48–0.58). Half (52%; n = 121) attended private facilities. Independent factors associated with knowledge about ANC were age ≥30 years (OR 2.2, 95%CI 1.1–4.6), monthly household income greater than 20,000 Bangladeshi Taka (OR 3.4, 95%CI 1.4–8.6); knowledge of pregnancy-related complications (OR 3.6, 95%CI 1.6–8.1), knowledge about nearest health facilities (OR 4.3, 95%CI 2.1–8.8); and attending secondary school or above (OR 4.8, 95%CI 2.1–11). Independent factors associated with attending ANC services were having prior knowledge of ANC benefits (OR 7.7, 95%CI 3.6–16), Indigenous women residing in Khagrachhari Sadar subdistrict (OR 6.5, 95%CI 1.7–25); and monthly household income of 20,000 Bangladeshi Taka or above (OR 2.8, 95%CI 1.1–7.4). Conclusion: Approximately half of Indigenous women from Chittagong Hill Tracts Bangladesh attended ANC services at least once. Better awareness and education may improve ANC attendance for Indigenous women. Cultural factors influencing attendance need to be explored. [ABSTRACT FROM AUTHOR]

Background: Increased maternal health care (MHC) service utilisation in Bangladesh over the past decades has contributed to improvements in maternal health outcomes nationally, yet there is little understanding of Indigenous women's experiences of accessing MHC services in Bangladesh. Methods: Face-to-face semi-structured qualitative interviews with 21 Indigenous women (aged 15–49 years) within 36 months of delivery from three ethnic groups (Chakma, Marma and Tripura) were conducted between September 2017 and February 2018 in Khagrachhari district. Purposive sampling was used to recruit women representative of the population distribution in terms of age, ethnic community and service use experience. All interviews were conducted in Bangla language and audio-recorded with consent. Interviews were transcribed directly into English before being coded. Data were analysed thematically using a qualitative descriptive approach aided by NVivo12 software. Results: Of the 21 women interviewed, 14 had accessed at least one MHC service during their last pregnancy or childbirth and were categorised as the User group. The remaining seven participants were categorised as 'Non-users' as they had not access antenatal care, facility delivery or postnatal care services. Women reported that they wanted culturally relevant, respectful, home-based and affordable care, and generally perceived formal MHC services as being only for complications and emergencies. Barriers to accessing MHC services included low levels of understanding about the importance of MHC services, concerns about service costs, limited transport and fears of intrusive practices. Experiences within health services that deterred women from accessing future MHC services included demands for unofficial payments and abusive treatment by public facility staff. Conclusion: Improving access to MHC services for the CHT Indigenous women requires improved understandings of cultural values, priorities and concerns. Multifaceted reform is needed at individual, community and health systems levels to offer culturally appropriate health education and flexible service delivery options. [ABSTRACT FROM AUTHOR]
