Plain English Summary

Background and study aims
More and more people are now suffering from long-term diseases and multimorbidity (multiple medical conditions in one person), and are treated with an increasing number of long-term drugs. However, polypharmacy (use of multiple medications by a patient) involves severe risks for patient safety. Also, patients are often unable to monitor their frequency of dosage. Reducing inappropriate polypharmacy will contribute to lower levels of adverse drug events and drug-related side effects and will increase patient safety and quality of life. This study will test the effectiveness of an intervention (use of pharmacist-based narrative medication review) within hospitals and aims at reducing the number of long-term prescribed drugs among multimorbid and chronically ill patients.

Who can participate?
Patients aged 60 years and older, taking five or more prescribed long-term drugs, and likely to spend at least one week in the hospital.

What does the study involve?
The hospital wards are randomly allocated to either the intervention or the control group. Patients in the intervention wards receive a pharmacist-based narrative medication review in hospital. Patients in the control group wards will receive care as usual. The study compares the number of prescribed long-term medications between both groups at 12 months after discharge as well as health-related quality of life.

What are the possible benefits and risks of participating?
The findings of this study may result in a major impact on reducing polypharmacy by enhancing both patient-centeredness and patient autonomy. No risks to participants are expected.

Where is the study run from?
Two hospitals in Mecklenburg-Western Pomerania, Germany.

When is the study starting and how long is it expected to run for?
The study will be conducted between November 2013 and October 2016.

Who is funding the study?
German Federal Ministry of Education and Research (BMBF).

Patients with chronic diseases and polypharmacy (≥ 5 prescribed long-term drugs)


During in-patient treatment of chronically ill patients affected by polypharmacy, a pharmacist specially trained in communication skills performs a narrative-based medication review. Apart from detecting potentially inadequate medication, a major aim is to identify patient preferences and to include them - whenever possible - into a list of evidence-based medication recommendations. Patients will be motivated to narrate the drugs they currently take and describe their experiences and expectations related to these drugs. Based on this information the pharmacist prepares a list of possible drugs to be stopped, which will then be discussed with the hospital physician in charge and will be submitted for consent to the patients’ General Practitioner. The active involvement of patients allows for transparency of the decision-making process and will increase the chance for a sustainable medication optimization.

Patients of the control group receive care as usual.

The intervention in the intervention group will take place once, shortly after the admission to hospital. The duration of the entire trial will be 36 months.

Primary outcome measures

The two independent main outcomes are:
1. Health-related quality of life (EQ-5D)
2. The difference in the number of prescribed long-term pharmaceutical agents between intervention and control group at T3.
Primary outcome is defined as pharmaceutical agents rather than number of drugs because combination drugs are commonly used in Germany.

During the baseline and intervention periods, primary outcomes for each patient will be measured at four points in time: at admission to the hospital (T0) and discharge from hospital (T1), as well as 6 (T2) and 12 months (T3) after discharge from the hospital.

Secondary outcome measures

1. Appropriateness of prescribed medication
2. Patient satisfaction
3. Patient empowerment
4. Patient autonomy
5. For all patients insured with the largest public German health insurance provider AOK, cost effectiveness and further aspects of quality of care will be analyzed.

Measured at T0, T2 and T3.

Participant inclusion criteria

Two local hospitals will recruit patients with chronic diseases and polypharmacy meeting the following inclusion criteria:
1. Aged 60+ years
2. Taking ≥ 5 prescribed long-term drugs
3. Likely to spend at least one week in the hospital

Participant type


Age group




Target number of participants

1,626 patients. After baseline: stratified randomization of participating wards. Wards allocated to control and intervention group will recruit another 1,626 patients.

Participant exclusion criteria

Exclusion criteria for participating patients:
1. Inability to take their medication by themselves
2. Inability to give informed consent (e.g. due to dementia)
3. Severe language difficulties
4. Diseases that usually make poly-pharmacotherapy unavoidable (e.g. active malignoma, acquired immunodeficiencies [HIV], hemodialysis)
5. Presumed life expectancy of less than 12 months
