The Effects of Online Access to General Practice Medical Records Perceived by Patients: Longitudinal Survey Study

Background: Patient online access to medical records is assumed to facilitate patient empowerment and advance patient-centered health care. However, to date, the actual effects of online access to medical records perceived by patients and other outcomes are insufficiently empirically tested.Objective: This study aimed to investigate the effects of online access to medical records on patient empowerment, informed decision-making, and the patient-provider relationship perceived by patients.Methods: A nationwide, 2-wave, longitudinal survey study was conducted among Dutch adults (N=2402). Linear regression analyses were performed. In model 1, the perceived effects of online access to medical records (measured at T1 [first measurement; July 2021]) on 16 outcomes (measured at T2 [second measurement; January 2022]), which were associated with the use of online access to general practice medical records in previous research, were investigated. Model 2 included sociodemographic factors and patient characteristics as confounders.Results: Users indicated more strongly than nonusers that online access to medical records would increase their participation in health care, improve the relationship with their general practitioner, and support informed decision-making. These results were robust when adjusted for the influence of confounders. Effect sizes were very small, with unstandardized regression coefficients (B) ranging between -0.39 and 0.28. Higher digital and health literacy were associated with higher ratings of almost all effects.Conclusions: Online access to medical records has the potential to empower patients and foster informed decision-making among patients. The effects in this study were small but might grow over time. Other factors, such as the attitude of general practitioners toward online access to medical records, might moderate these effects. The results indicate that the potential benefits of online access to medical records might be unevenly distributed. We suggest future exploration of the conditions under which online access to medical records can improve health care system functioning and efficiency without increasing health inequality.

Automated summary

This study aimed to investigate the effects of online access to medical records on patient empowerment, informed decision-making, and the patient-provider relationship. The results showed that users were more likely than nonusers to believe that online access to medical records would increase their participation in healthcare, improve their relationship with their general practitioner, and facilitate informed decision-making. Overall, online access to medical records has the potential to empower patients and enhance informed decision-making, but the effects are small.
