Point-of-Care Testing Enhances Health Literacy and Self-Management in Chronic Disease

Limited access to general practitioners and pathology services can delay diagnosis and monitoring for people in regional and remote communities. Rapid, on-the-spot testing can shorten turnaround times and reduce travel and costs, but its effect on patient engagement is less clear. Understanding whether immediate results improve self-management is critical for chronic disease care. New findings demonstrate how point-of-care testing can enhance health literacy and patient confidence.

Flinders University (Adelaide, Australia) evaluated point-of-care testing (POCT), pathology assays performed at or near the site of care that generate results during the same visit. Examples include finger-prick blood tests that enable immediate review with a clinician rather than days later via a centralized laboratory. The analysis examined whether POCT influences health literacy, defined as the ability to access, understand, remember, and use health information in daily life.

Published in BMC Public Health, the systematic review assessed 13 studies from multiple countries and included more than 21,000 participants. Most studies focused on non-communicable diseases, particularly diabetes and cardiovascular disease. Outcomes extended beyond clinical endpoints to capture changes in patient understanding of disease, confidence in self-management, motivation for lifestyle modification, and measures such as anxiety and quality of life.

Across cohorts, POCT was associated with better understanding of conditions and increased confidence in self-management, together with greater motivation to improve diet and physical activity. Several studies reported improved medication adherence and favorable shifts in clinical markers, including reductions in long-term blood glucose among people with diabetes. Parents of children with diabetes reported higher confidence when immediate results were available, and community testing initiatives prompted participants to consider healthier choices.

The review was led by Flinders University, including the Flinders Health and Medical Research Institute’s International Center for Point-of-Care Testing. Authors noted that speed and clinical context may shape how patients engage with test results, supporting conversations that connect everyday decisions with long-term outcomes. They also called for research on equitable, scalable deployment of POCT, especially where access to traditional laboratory testing is limited.

“When people receive their results straight away and can talk through what they mean with a health professional, it changes how they engage with their health. It helps turn test results into knowledge people can actually use,” said Dr. Kelcie Miller, lead author, College of Medicine and Public Health, Flinders University.

“Point-of-care testing delivers information in a way that is immediate and meaningful. It supports conversations, builds confidence and helps people connect everyday choices with long-term health outcomes,” said Mark Shephard, Matthew Flinders Professor and Founding Director, FHMRI International Center for Point-of-Care Testing, Flinders University.
