Primary Health Care System SEED FUNDING REPORTS
Abstract :Objective: To evaluate the feasibility of an aspect of data quality (data reliability) improvement in four specific areas of the electronic medical record (EMR) chart: diagnostic coding for a chronic disease [chronic obstructive pulmonary disease (COPD)]; structured data entry for a risk factor (smoking); structured specialist referral designation (meta-data) and interprofessional encounter designation. Design: Feasibility project incorporating an evaluation of data quality with a quasi-experimental before and after evaluation of a data quality management intervention. Participants: Thirteen community-based family physicians that are members of an interdisciplinary Family Health Team (the North York FHT). Intervention: Once baseline measures were recorded, a data clerk was then tasked with correcting the data as follows: a) changing all unstructured smoking data into structured categories; b) with physician permission, adding the ICD9 COPD code “496” in the cumulative patient profile (CPP) instead of free text; c) changing referral designations in the address book of the EMR to conform with College of Physicians and Surgeons of Ontario specialist designation ; d) adding interprofessional encounter headers to the EMR if not present and inform Allied Health Professionals (AHPs). The participating physicians and AHPs were provided with “data manuals” suggesting improved methods of data entry, along with screen shots. Main outcome measure: EMR data quality was measured as outlined above at baseline and six months. Evaluation of acceptability by physicians will be measured through a questionnaire incorporating usefulness and usability at 6 months (in progress). Results: Unstructured smoking data decreased from 29% to 2% at 6 months after data entry. Coded COPD entries in the CPP increased from 56% to 96%. Referrals with specialist designations increased from 50% to 71%. Identifiable interprofessional headers increased from 28% to 37%. A statistical analysis is underway. The data entry clerks spent 53 hours restructuring the smoking data, 3 hours on recoding COPD, 70 hours on adding specialist designations to the address book. Interprofessional headers were added in less than an hour. Conclusion: This intervention (using a data clerk to restructure data in the four areas of the EMR we indentified) led to measureable improvements in the aspects of data reliability we measured, with a reasonable use of resources such as time and personnel. The results could be used to plan a phase 2 study. Key Messages:
