The value proposition for point-of-care testing in healthcare: HbA1c for monitoring in diabetes management as an exemplar

Point-of-care testing (POCT) is a key enabling technology for disruptive and transformative innovation in healthcare, allowing tests to be performed quickly and close to the patient. This results in faster clinical decision making and new, more efficient models of care, with clinical, process and economic benefits potentially accruing to all stakeholders. Recognised barriers to the adoption of new technology such as POCT include poor understanding of current practice and thus the unmet need, the challenges of process change, and reluctance to disinvest in redundant resources resulting from improved pathway efficiency. Major contributors to this problem include a background of funding, organisation and management of healthcare that fails to recognise the complexity of a multiple stakeholder health economy seeking to become more outcomes-based and value driven. We examine the concept of a structured value proposition as a generic tool to achieve better adoption of POCT using as an example, the evidence that is available for the rapid measurement of glycated haemoglobin (HbA1c) in the management of diabetes. We highlight the key components of the value proposition, identifying the impact of the test result on all stakeholders and the metrics which are required to define current practice (e.g. a laboratory-based HbA1c testing service), in order to develop the business case and the implementation plan required to demonstrate effective adoption of a POCT-based service. We conclude that the value proposition helps to identify the potential benefits to be gained from using POCT, and the stakeholders to whom they accrue.
