Accelerating implementation of district health information systems: perspectives from healthcare workers from KwaZulu-Natal, South Africa

Background: Although electronic health record systems are critical for healthcare management, there has been genuine concern about the quantity and quality of data generated by these systems inhibiting its full implementation. Objectives: The purpose of this article was to explore the experiences of healthcare workers (HCWs) and challenges facing the acceleration of the District Health Information System (DHIS) in the KwaZulu-Natal (KZN) province of South Africa. Methods: In this study, an interpretive research paradigm was followed to explore the current state of electronic health in South Africa from the experiences of HCWs in the KZN province. Semi-structured focus group interviews conducted with 20 participants drawn from the district office, clinical nurse practitioners and data capturers allowed thematic analysis of data using a systems approach to link the perspectives HCWs to the design of the DHIS. Results: The participants held the view that e-health is crucial for monitoring disease trends, policy development, planning and allocation of infrastructure, information technology (IT), financial and human resources. Nevertheless, the participants highlighted a concern surrounding e-health regulations, ethics and data confidentiality; data quality and lack of interoperability of Health Information Systems (HIS). This concern was attributed to data fragmentation, internal politics and lack of coordination of the data system. Conclusions: The study suggests that good quality data ­ from an integrated DHIS, is highly critical for the effective utilisation, implementation and acceleration of e-health systems in the province to support epidemiological surveillance and modelling of outbreaks, such as the COVID-19 pandemic.

An investigation in the remineralization and acid resistant characteristics of nanohydroxyapatite produced from eggshell waste via mechanochemistry.

OBJECTIVES: This study focuses on the properties of nanohydroxyapatite (nHAp) in terms of remineralization and acid resistance. The nHAp were produced from waste eggshells via the mechanochemistry process. MATERIALS AND METHODS: The characterization was based on Fourier Transform Spectroscopy, X-ray diffraction, Field Scanning Electron Microscope (FESEM), and High-Resolution Electron Microscope to determine the surface morphology of the nHAp. The acid and remineralization properties were evaluated using bovine enamel and dentine models (n = 5) while the buffering properties against acids were studied using a pH meter. The biocompatibility of the produce nHAp was assessed in vitro against NIH 3T3. RESULTS: The XRD and FTIR results confirm that nHAp were successfully produced from eggshell waste after 5 h of milling. The HRTEM reveals a semi-sphere morphology with an average dimension of 9 to 20 nm. The buffering test suggests that nHAp were highly effective in neutralizing common dietary acids. Also, the nHAp exhibits outstanding remineralization and occluding properties. The cytotoxicity assay suggests that the nHAp had a low toxicity. CONCLUSION: The study concludes that using eggshell waste to produce nHAp will help in waste management and at the same time, provide valuable biomaterial for the treatment of tooth sensitivity.
