Objective: To describe the overall drug use in Swedish nursing homes and to
comment on the impact of regular multidisciplinary team interventions on t
he quantity of inappropriate medications.
Design and Setting: This randomised, controlled trial was carried out in a
sample of 33 nursing homes, 15 experimental homes and 18 control homes, rep
resenting 5% of all Swedish nursing homes.
Participants: The sample consisted of 1854 nursing home residents with an a
verage age of 83 years. 70% of the residents were female and 42% had a docu
mented diagnosis of dementia. An additional 5% had a psychotic disorder and
7% had a diagnosis of depression.
Measurements: Lists of each resident's prescriptions were collected 1 month
before and 1 month after the 12-month intervention. Measures included the
proportion of residents receiving any particular drug. The number of drugs
classified by guidelines as inappropriate was also measured before and afte
r the intervention period.
Results The nursing home residents were prescribed on average 7.7 medicatio
ns, the majority on a regular basis. The most frequently prescribed group o
f drugs was laxatives, followed by psychotropic agents and cardiovascular d
rugs. Some groups of drugs decreased in the intervention homes.
Conclusion: Extensive and somewhat inappropriate drug use in Swedish nursin
g homes is a significant and serious problem. Careful monitoring is necessa
ry to ensure well tolerated drug therapy in this frail population. Neither
written information from the Medical Products Agency, nor the campaign in t
he pharmacies alone had an impact on drug use in Swedish nursing homes. Mul
tidisciplinary team discussions contributed to improved drug use, but more
research is needed to understand the mechanisms behind this finding.
