[Cost-effectiveness of digital care and face-to-face care in the first-level of care].

Background: The medical care paradigm is face-to-face; however, technological development has led to the digital modality. Objective: To determine cost-effectiveness of digital care and face-to-face care at the first level of care. Material and methods: Cost-effectiveness study. 2 groups were integrated: the digital service and the face-to-face service. The sample size was calculated with the percentage formula for 2 groups, and the result was 217 per group. The effectiveness was evaluated in 3 dimensions: the satisfaction of the patient, of the doctor and of the medical assistant. In all 3 cases the Visual analogue scale was used. The cost corresponded to the fixed unit cost estimated with the technique of times and movements adjusted for the duration of care. The statistical analysis included averages, percentages and cost-effectiveness ratio. Results: The cost of digital attention is $343.83 and face-to-face attention is $171.91 (all estimated in Mexican pesos). From the patient's perspective, the effectiveness in digital care is $9.47 and in face-to-face is $9.25. The cost to reach effectiveness of 10 in face-to-face care is $185.85 and in digital care $363.20. From the physician's perspective, the cost to achieve effectiveness of 10 is $419.13 in digital care and $184.52 in face-to-face care. From the perspective of the medical assistant, to achieve effectiveness of 10, the cost in digital care is $468.43 and in face-to-face $179.83. Conclusions: Currently, the best cost-effectiveness ratio corresponds to face-to-face care; however, digital care is an option that will have to evolve.
