Brief summary

The aim of this randomized controlled study is to investigate if medication reviews performed by a clinical pharmacist as part of a ward team can reduce drug related problems and reduce readmissions to hospital among elderly patients (≥65 years) with dementia and cognitive failure. Four hundred and sixty patients will be recruited and randomized to control (usual care) and intervention group (enhanced service in which a pharmacist is part of the health care team). Six months after the last patient of the 460 has been discharged the study will be closed. Data about the number of readmissions and visits to the emergency room will be collected during the six-month follow-up and also, the costs associated with each visit or admission. Time until institutionalization will be compared between intervention group and control group.

Interventions

OTHERMedication review

In the intervention, the pharmacist will evaluate: * Is there an indication for the drug? * Has the drug desired effect? * Is the dose correct and dosing scheme correct? * Side effects, contraindications, inappropriate drugs * Interactions * Treatment time * Cost effectiveness * Adherence to recommendation list * Problems with handling the drugs (for example crushing of the tablets) * Untreated indication * Double medications * Administration of drugs

Change in the Number of Participants With Potentially Inappropriate Medications, According to the Swedish National Board of Health and Welfare, at Admission and Discharge Between Intervention and Control Group

Six drug-specific quality indicators as defined by the Swedish National Board of Health and Welfare were used to define use of Potentially inappropriate medications (PIMs) in this study. Four out of the six selected indicators belong to a group where drug-use should be as low as possible regardless of indication: anticholinergic drugs (as defined by the Swedish National Board of Health and Welfare, propiomazine, tramadol, and long-acting benzodiazepines. The two remaining indicators are classified as preparations for which correct and current indication is of particular importance: antipsychotic drugs (N05A except lithium) and Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). In the present study, a PIM was defined as exposure to at least one of the drugs mentioned among the six quality indicators.
