The purpose of this study was to describe patients' learning needs after hip arthroplasty and compare them prior to and 2 weeks after hospital discharge. Data were collected in two phases from 22 surgical wards in 17 hospitals in Finland using a Canadian Patient Learning Needs Scale (Galloway et al., 1996). The first questionnaire (n=212, 81%) was completed before hospital discharge and the second (n=144, 55%) was completed at home after hospital discharge. Results indicated that patients' learning needs diminished significantly after hospital discharge. In both questionnaires patients felt that the most important information was about complications and symptoms. Information about medication was ranked the second most important. Demographic variables such as age, gender, education and working life were clearly related to learning needs. Women over 60 years old, and less educated and retired respondents had many learning needs.
