Association between sanitary toilets and health poverty vulnerability among rural western Chinese adults aged 45 years and older: A cross-sectional study

This study aimed to investigate the association between sanitary toilets and health poverty vulnerability among rural western Chinese adults aged 45 years and older. Using data from the 'Rural Household Health Inquiry Survey' conducted in 2022, a three-stage feasible generalized least squares method was employed to calculate health poverty vulnerability. Propensity score matching (PSM) and mediation effect analysis were used to assess the association between sanitary toilets and health poverty vulnerability among rural western Chinese adults aged 45 years and older and the mechanisms underlying this impact. This study revealed that the use of sanitary toilets was significantly associated with decreased health poverty vulnerability in adults over 45 years of age. Heterogeneity analysis revealed that this effect was more pronounced among males (β = -0.0375, P<0.05), those aged 60-74 years (β = -0.0476, P<0.05), and households with middle income (β = -0.0590, P<0.01). Mediation effect analysis identified total household income (a×b = -0.0233, P<0.05), household size (a×b = -0.0181, P<0.01), number of household laborers (a×b = -0.0107, P<0.01), and registered poor households (a×b = -0.0081, P<0.01) as the mediating factors between sanitary toilets and health poverty vulnerability. The provision of sanitary toilets has been instrumental in mitigating health-related poverty among middle-aged and elderly people residing in rural areas. By improving household livelihood capital, the vulnerability of these individuals to health-related poverty can be significantly reduced.

Do Integrated Community Psychiatry Services in Primary Health Care Settings Improve Continuity of Care? A Mixed-methods Study of Health Care Users' Experiences in South Africa

Background

A community psychiatry service is provided from selected primary health care (PHC) clinics in Gauteng, South Africa. This study described the demographic and clinical characteristics of health care users (HCUs), and explored HCUs' experiences of these services in order to shed light on the challenges of integrating psychiatric services into PHC.

Methods

A mixed-methods study was conducted at two PHC clinics, where 384 clinical records were reviewed and 23 HCUs were interviewed. In Clinic-1, community psychiatry services were co-located, while in Clinic-2, these services were physically integrated into the PHC clinic.

Results

HCUs from both clinics were generally female (55%), had not completed secondary level education (65%), and were unemployed (80%). Both clinics struggled with medication stock-outs and had the same number of community psychiatry health care providers. Compared to the co-located clinic, the physically integrated clinic had insufficient consultation rooms (compromising confidentiality), higher caseloads (910 compared to 580), more HCUs with psychotic disorders (61% compared to 44%) and a history of missed medication (58% compared to 40%). In both clinics, overall care coordination was limited, although some nurses coordinated care for HCUs. While organisational integration approaches improved the proximity of mental health services, there were challenges in continuity of care within and across health care sites.

Conclusion

Coordination and continuity of care were constrained in both clinics, regardless of the organisational integration approaches used. As low- and middle-income countries work towards integrating mental health care into PHC, the implementation of organisational integration approaches should consider physical space, caseload, HCU need, and the inclusion of dedicated providers to coordinate care.

Patient Safety Culture: Nurses' Perspective in the Hospital Setting

(1) Background: Patient safety culture (PSC) encompasses the values, attitudes, norms, beliefs, practices, perceptions, competencies, policies, and behaviours of professionals that determine organisational commitment to quality and patient safety. Few studies use mixed methods to analyse patient safety culture, and none offer the richness of using a mixed methodology to develop their theoretical model. This study aims to identify the factors nurses believe contextualise and influence PSC in relation to existing theoretical frameworks. (2) Methods: This study employed a sequential explanatory mixed-methods design combined with the Pillar Integration Process for data integration. (3) Results: In the final data integration process, 26 factors affecting nurses' PSC were identified. Factors nurses related to PSC not being assessed with the tool used in phase 1 were notification system, flow of patients, patient involvement, resources and infrastructure, and service characteristics. (4) Conclusions: This mixed-methods study provides an opportunity to identify the weaknesses and strengths of currently developed theoretical frameworks related to PSC and offers content for its improvement. Even though multiple studies aim to assess PSC using existing quantitative method tools, the development of this study offers a glimpse of some aspects relevant to nurses' PSC not included in the theoretical framework of the said tools, such as patient involvement, the flow of patients, and service infrastructure.

Prevalence of Human Norovirus GII.4 Sydney 2012 [P31] between 2019 and 2021 among Young Children from Rural Communities in South Africa

Acute gastroenteritis (AGE) accounts for considerable morbidity and mortality in the paediatric population worldwide, especially in low-income countries. Human norovirus (HNoV), particularly GII.4 strains, are important agents of AGE. This study aimed to detect and characterise HNoV in children with and without AGE. Between 2019 and 2021, 300 stool samples (200 AGE and 100 without AGE) were collected from children below 5 years of age referred to the healthcare facilities of the rural communities of Vhembe District, South Africa. After detection using real-time RT-PCR, HNoV positive samples were subjected to RT-PCR and Sanger sequencing. Partial nucleotide sequences (capsid/RdRp) were aligned using the Muscle tool, and phylogenetic analysis was performed using MEGA 11. The nucleotides' percent identity among HNoV strains was compared using ClustalW software. A significant difference in HNoV prevalence between AGE children (37%; 74/200) and non-AGE (14%; 14/100) was confirmed (p < 0.0001). Genogroup II (GII) HNoV was predominant in AGE children (80%; 59/74), whereas most non-AGE children were infected by the GI norovirus genogroup (64%; 9/14). GII.4 Sydney 2012 [P31] strains were dominant (59%; 19/32) during the study period. A phylogenetic analysis revealed a close relationship between the HNoV strains identified in this study and those circulating worldwide; however, ClustalW showed less than 50% nucleotide similarity between strains from this study and those from previously reported norovirus studies in the same region. Our findings indicate significant changes over time in the circulation of HNoV strains, as well as the association between high HNoV prevalence and AGE symptoms within the study area. The monitoring of HuNoV epidemiology, along with stringent preventive measures to mitigate the viral spread and the burden of AGE, are warranted.

A bottom-up view of antimicrobial resistance transmission in developing countries

Antimicrobial resistance (AMR) is tracked most closely in clinical settings and high-income countries. However, resistant organisms thrive globally and are transmitted to and from healthy humans, animals and the environment, particularly in many low- and middle-income settings. The overall public health and clinical significance of these transmission opportunities remain to be completely clarified. There is thus considerable global interest in promoting a One Health view of AMR to enable a more realistic understanding of its ecology. In reality, AMR surveillance outside hospitals remains insufficient and it has been very challenging to convincingly document transmission at the interfaces between clinical specimens and other niches. In this Review, we describe AMR and its transmission in low- and middle-income-country settings, emphasizing high-risk transmission points such as urban settings and food-animal handling. In urban and food production settings, top-down and infrastructure-dependent interventions against AMR that require strong regulatory oversight are less likely to curtail transmission when used alone and should be combined with bottom-up AMR-containment approaches. We observe that the power of genomics to expose transmission channels and hotspots is largely unharnessed, and that existing and upcoming technological innovations need to be exploited towards containing AMR in low- and middle-income settings.
