To maximize the impact of novel diagnostics on patient outcomes in resource-limited settings, the implementation of new diagnostics must be performed within a given context and culture. However, the population-level of diagnostic utility in South Africa is not known. The investigators aim to estimate the level of POC diagnostic availability, usage and need in rural South Africa, using a cross sectional survey of rural primary healthcare (PHC) clinics in KwaZulu Natal (KZN). The survey focused on the conditions for which the respondent considered a POC test might help improve their clinical decision making during patient care. Determining the current accessibility, availability, usage and need for POC diagnostics in rural and resource limited settings can help inform developers and implementers of POC diagnostic services on context-specific deployment and implementation of POC diagnostics to address the unmet needs of patients in these settings.
