Potential clinical impact of extended point-of-care testing. Extended point-of-care testings’ potential for clinical impact by identifying additional participants with conditions in need of clinical decision-making compared to usual in-home assessments. A ACNs identified 48 out of 100 participants in need of clinical decision-making by a primary care physician. Extended POCT identified additional 34 participants with a condition in need of clinical decision-making, not identified by the usual in-home assessment. Each specific POCT is illustrated in B, C, D, except for PCR for upper respiratory tract infection and urine flow-cytometry, as results did not change clinical decision-making: B Focused Lung ultrasound identified 21 participants with a condition in need of clinical decision-making not identified by the ACNs in-home assessment. (Feasibility 100%). C POCT for leucocytes with differential count identified 16 participants with a condition in need of clinical decision-making not identified by the ACNs in-home assessment. (Feasibility 89%). D POCT for creatinine identified 9 participants with a condition in need of clinical decision-making not identified by the ACNs in-home assessment. (Feasibility 89%).
