ABSTRACT
Village Health Workers (VHWs) in Zimbabwe complement the healthcare staff in primary health care delivery. In 2015 the Ministry of Health streamlined services offered by the VHWs with the VHW Strengthening Plan to improve the effectiveness of the program. However, these continue to offer services not addressing the current and emerging health problems. This three-phased study seeks to develop strategies to improve the effectiveness and efficiency of VHWs in service delivery. Systematic literature review shall be used to develop a conceptual framework to guide the development of VHWs service delivery strategies. Exploratory sequential mixed methods design shall explore VHWs roles in primary health care. A survey in the first stage shall collect qualitative data from 45 purposely selected healthcare workers and VHWs using interviews and then thematically analyzed with MAXQDA. The variables generated will have a cross-sectional survey used to collect quantitative data from 134 VHWs and analyzed on SPSS. The SWOT and basic logic models shall be used to develop strategies validated by the Delphi Technique and Key Stakeholders. Informed consent will be maintained in the study with findings published in journals and presentation symposiums. This protocol was approved by the University of Venda Research Ethics Committee (Registration FHS/23/pH/11/0709).
ABSTRACT
The maternal death rate remains high in South Africa despite the availability of many existing strategies to improve the quality of service. A 30% increase in the maternal mortality rate was reported between 2020 and 2021, with Limpopo ranking fourth highest out of nine provinces. The Vhembe district maintained its position as the third-ranked area with a notably elevated maternal mortality rate. This study aimed to explore the strategies used to reduce the maternal death rate and improve the provision of quality maternal healthcare services based on participant experiences in selected hospitals of the Vhembe district, Limpopo Province. One hospital was purposively sampled from every four municipalities. A qualitative approach using a phenomenological design was employed. Twenty-eight participants were sampled using a convenience sampling method. The semi-structured interview guide was used to collect data, complemented by the use of an audio recorder, continuing until data saturation was reached. Data saturation was reached at the 20th participant; however, the researcher continued until 28 sampled participants were interviewed. An interpretative phenomenological analysis was used following the analytical stages of interpretative data analysis. The study proposal was ethically cleared by the University of Venda Ethics Committee (FHS/22/PH/08/3108). The results indicate that, despite implementing strategies to improve maternal healthcare services and reduce the maternal death rate, several factors, such as the lack of material resources, shortage of staff, incompetent staff and poor infection control, affect the quality of maternal health services in the Vhembe district. The Limpopo Department of Health and hospital management should ensure that hospitals have all the necessary resources and support healthcare professionals through in-service training to ensure the functionality of existing strategies.
ABSTRACT
BACKGROUND: According to WHO, in 2015, over 35% of ischaemic heart disease, the leading cause of death and disability worldwide, and about 42% of strokes, the second largest contributor to global mortality, could have been prevented by reducing or removing exposure to chemical pollutants. Heavy metal and cyanide pollution are prevalent in developing countries, especially in sub-Saharan Africa where the effects of industrial pollutants are more severe, partly due to poor regulation. In Zimbabwe, the mining industry alone contributed to 25% of occupational conditions and injuries in 2020. Therefore, to mitigate these problems, this study seeks to develop a health risk management framework for heavy metals and cyanide pollution in the industrial city of Kwekwe. METHODS: The convergent parallel mixed-method study design will be utilised. Qualitative and quantitative data will be collected, analysed, and merged in order to inform the development of the risk framework. An analytical cross-sectional survey would be used to determine levels of heavy metals in surface water, soil, and vegetables. Free cyanide will be determined in surface water samples only. The phenomenological qualitative inquiry will be used to investigate health events and risks associated with potentially toxic pollutants (heavy metals and cyanide) to describe or interpret participants' lived experiences. The qualitative and quantitative results will be used to develop and validate the framework to manage identified health risks. For data analysis, statistical analysis will be used in the quantitative study, while thematic analysis will be used in the qualitative study. The study was approved by the University of Venda Ethics Committee (Registration Number FHS/22/PH/05/2306) and the Medical Research Council of Zimbabwe (Approval Number MRCZ/A/2944). All ethical principles will be adhered to throughout the study in accordance with the Helsinki Declaration. DISCUSSION: While existing risk management frameworks have significantly contributed to human and environmental health protection, novel and comprehensive frameworks need to be developed to counter the ever-dynamic and evolving risks associated with chemical pollutants. If the management framework is successfully developed, it could offer an opportunity for the prevention and control of potentially toxic elements.
In Zimbabwe, just like most developing countries, the problem of environmental pollution continues to threaten and endanger public health. Current pollution management measures seem insufficient in combating the problem to the extent that communities living in or near industrial areas continue to suffer from associated acute and chronic health conditions. Kwekwe city is an industrial and mining area with several abandoned and active mines and processing plants. Artisanal mining is widespread in the area, and many parts of the city's landscape are littered with open mining pits, dumps, and abandoned tailings. Most of these facilities are potential sources of heavy metals and cyanide and pose risks to human health. This study, therefore, seeks to develop a health risk management framework to address problems, which are associated with anthropogenic pollutants such as heavy metals and cyanide. The study will be conducted in two phases, that is, the first phase would involve the collection and analysis of empirical data from environmental samples, residents, and key stakeholders on heavy metal and cyanide pollution and associated health risks. The second phase would utilise findings from the first phase to develop a regulatory framework and to manage identified health risks. The developed framework would be validated through stakeholder and expert participation. The developed health risk management framework could be useful in the prevention and control environmental contamination, hence assisting to improve non-communicable diseases' outcomes in Kwekwe city.
