This study aims to review the literature evaluating the design, acceptance, use and usability of inpatient portals for family caregivers. Fourteen articles were included. Information about patient medication, lab results and healthcare team was most important. Most caregivers were satisified and perceived the ease of use and usefulnesss of portals. Further research is needed to collect sufficient evidence with regard to the impact of inpatient portals on patient engagement and quality of care.
