Drug Prescriptions in Nursing Home Residents during their Last 6 Months of Life: Data from the IQUARE Study

Drug prescribing changes in the last year of life among homebound older adults: national retrospective cohort study

OBJECTIVES

This study aimed to evaluate the prescription patterns of drugs during the last year of life in homebound older adults who received home medical care.

METHODS

We used a nationwide claims database in Japan and selected older adults aged ≥75 years who received home medical care services from ≥12 months before their death. We evaluated medications prescribed 12 months before death (month 12), 3 months before death (month 3) and in the last month of life (month 1). We explored the factors associated with the decreased number of cardiovascular preventive drugs from month 12 to both month 3 and month 1.

RESULTS

A total of 118 661 participants were included, and the majority were aged ≥90 years and women. The prevalence of cardiovascular preventive drugs decreased but remained common in month 1, which included antihypertensives (34.7%), antiplatelets (15.9%), oral anticoagulants (7.6%), antidiabetic drugs (7.3%) and lipid-lowering drugs (6.1%). The relative decrease from month 12 to month 1 was the largest for lipid-lowering drugs (44.8%) and the smallest for oral anticoagulants (13.6%). Among other drugs, laxatives (enema), antiemetics, oral corticosteroids, analgesics, expectorants, bronchodilators and antibiotics showed a large relative increase. Older age, duration of home medical care services for <1 year and diagnoses of cancer, dementia and Parkinson's disease were associated with a greater likelihood of a decreased number of cardiovascular preventive drugs.

CONCLUSIONS

There is room for deprescribing to avoid inappropriate polypharmacy by balancing preventive and symptom management drugs in those receiving home medical care with a limited life expectancy.

Medication use in aged care residents in the last year of life: A scoping review

BACKGROUND

A substantial number of older adults die in residential aged care facilities, yet little is known about the characteristics of and how best to optimise medication use in the last year of life.

AIM

The aim of this review was to map characteristics of medication use in aged care residents during the last year of life in order to examine key concepts related to medication safety and draw implications for further research and service provision.

DESIGN

A scoping review following Arskey and O'Malley's framework was conducted using a targeted keyword search, followed by assessments of eligibility based on title and content of abstracts and full papers. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the scoping review protocol was prospectively registered to the Open Science Framework on 27 November 2018.

DATA SOURCES

We searched MEDLINE, EMBASE, AMED, CINAHL and Cochrane databases to identify peer-reviewed studies published between 1937 and 2018, written in English and looking at medication use in individuals living in aged care facilities within their last year of life.

RESULTS

A total of 30 papers were reviewed. Five key overarching themes were derived from the analysis process: (1) access to medicines at the end of life, (2) categorisation and classes: medicines and populations, (3) polypharmacy and total medication numbers, (4) use of symptomatic versus preventive medications and (5) 'inappropriate' medications.

CONCLUSION

Number of prescriptions or blunt categorisations of medications to assess their appropriateness are unlikely to be sufficient to promote well-being and medication safety for older people in residential aged care in the final stages of life.
