In this study, we explore how healthcare professionals in primary care and outpatient clinics perceive the outcomes of giving patients online access to their electronic health records. The study was carried out as a case study and included a workshop, six interviews and a survey that was answered by 146 healthcare professionals. The results indicate that professionals working in primary care perceive that an increase in information-sharing with patients can increase adherence, clarify important information to the patient and allow the patient to quality-control documented information. Professionals at outpatient clinics seem less convinced about the benefits of patient accessible electronic health records and have concerns about how patients manage the information that they are given access to. However, the patient accessible electronic health record has not led to a change in documentation procedures among the majority of the professionals. While the findings can be connected to the context of outpatient clinics and primary care units, other contextual factors might influence the results and more in-depth studies are therefore needed to clarify the concerns.
