Evaluation of the Association Between Different Patient Indexing Strategies and Effective Indexing in Health Centers of the Public System of the Autonomous City of Buenos Aires: An Exploratory Study

摘要

During the implementation of an electronic health record (EHR) system in the public system of the city of Buenos Aires, Argentina, different patient indexing strategies were devised and implemented. We sought to assess the association between these strategies and effective indexing (proportion of patients who are indexed and have a consultation registered in the EHR). Strategies were grouped into three modalities (High, Intermediate, and Low intensity). We estimated hazard ratios (HR) comparing the High and Low intensity to the Intermediate strategies. The crude analyses showed a significant difference between the curves (p < 0.0001). In the multivariate analysis, the HRs of High and Low intensity interventions showed on average, values above 1 from 0 to 90 days compared to the Intermediate intensity strategy (High: 2.08 (1.65, 2.52); Low: 2.59 (2.29, 2.9)). From that point on, the HRs of both strategies were not different from 1.
