Elderly patients have a higher risk of experiencing adverse drug events due to an age related increase in morbidity and medication use. Inappropriate or wrong medication use among elderly patients acutely admitted to hospitals is assumed to result in earlier contact to general practitioner, emergency departments and re-admissions if not corrected during hospital admission. It is therefore our hypothesis that a systematic medication review conducted by pharmacists and physicians specialized in pharmacology will increase time to first unscheduled physician contact (general practitioner, emergency departments, ambulatory care and re-admissions) after discharge from hospital from an average of 21days to 25 days. Further, the following secondary outcome parameters will be measured at discharge and within 3-month follow-up:

• length of in-hospital stay
• number of contacts to general practitioner 30 days after discharge, that resulted in medication changes
• number of re-admissions at 3-month
• number of death at 3-month
• number of contact to primary health care at 3-month
• patients self-experienced quality of health(EQ-5D) 3-month

Inclusion Criteria:

• age 65 years or older
• expected admission time of more than 24 hours
• acute admission

Exclusion Criteria:

• Psychotic patients
• Moribund patients
• Suicidal patients
