Acceptability and adoption of a multiparameter point-of-care testing (POCT) device in primary healthcare for non-communicable diseases in resourced-limited communities in Peru

ObjectivesTo assess the acceptability and adoption of multiparameter point-of-care testing (POCT) devices for the diagnosis and management of non-communicable diseases (NCDs) at the primary healthcare level in a resource-limited region of Peru.DesignQualitative case-control process evaluation.SettingEight primary healthcare facilities in northern Peru, including both urban and rural centres, where routine chronic care and laboratory services are provided.ParticipantsSixty-three participants: 36 patients, 12 laboratory technicians, 10 healthcare professionals and five facility heads. Eligible patients were ≥18 years, residing in the catchment area, with or without prior NCD diagnoses. Healthcare workers, including physicians, nurses, laboratory staff and facility managers.InterventionsMultiparameter POCT devices were installed in four intervention facilities, accompanied by staff training and community awareness activities, while four control facilities continued with conventional laboratory diagnostics.Primary and secondary outcome measuresPrimary outcome: perceptions of patients and healthcare workers regarding the acceptability and adoption of POCT devices. Secondary outcomes: identification of facilitators and barriers to implementation, including infrastructure, supply chains and training gaps.Results(1) Individuals: POCT was valued for speed and comfort, but concerns over accuracy were mentioned. (2) Intervention characteristics: laboratory staff valued POCT’s practicality in emergencies, but noted limitations in handling multiple samples. (3) Outer setting: urban centres outperformed rural facilities, with more staff and longer operating hours. (4) Inner setting: calibration gaps impacted POCT and conventional test reliability, requiring quality control and training. (5) Process: clear staff communication boosted patient confidence in POCT, but inconsistent training could lead to reliability doubts.ConclusionsMultiparameter POCT devices show promise for enhancing NCD care in resource-limited primary healthcare settings, particularly in rural areas. However, their sustainability depends on broader health system reforms, including reliable supply chains, expanded training and stronger quality assurance mechanisms. Further research should examine strategies for embedding POCT within national regulatory and policy frameworks.
