Multicenter prospective observational study on hospital pharmacist interventions to reduce inappropriate medications

Background: In Japan, the involvement of hospital pharmacists in inappropriate medications (IMs) practices has not been sufficiently reported. Therefore, this prospective study described the interventions of hospital pharmacists in discontinuing inappropriate drugs or reducing drug doses. Methods: We conducted a prospective, multicenter, observational study to investigate the intervention of hospital pharmacists in inappropriate prescriptions for inpatients in September 2018. Fifty pharmacists from 45 hospitals in Japan participated in this study. IMs were defined as medications that pharmacists deemed inappropriate for patient treatment. The subjects of the study were patients who interacted with the participating pharmacists. Results: During the study period, the median number of beds in hospitals where the 50 participating pharmacists worked was 380, and the average number of beds for which the pharmacists were responsible was 49. The enrolled hospital pharmacists recommended that doctors discontinue or reduce the doses of their regular drugs for 347 out of 1,415 (24.5%) patients. Among the 391 pharmacists' recommendations to reduce IMs for 347 patients, physicians accepted 368 (94.1%) recommendations, and 523 drugs were discontinued as a result. Pharmacist intervention also led to improvements in hypnotic sedation, delirium, and hypotension. The most common reasons for IMs identified by pharmacists were "long-term administration of irresponsible or aimless medications" (44.5%), "adverse effects caused by medications" (31.5%), and "medications-mediated duplication of the pharmacological effect" (15.3%). Approximately 90% of pharmacists' suggestions to reduce medications were accepted for each reason. The average number of regular medications used by patients involved in drug reduction was 8.2, and the average number of medications reduced was 1.7. A sub-analysis showed that patients using opioids tended to take more medications, and these patients were able to reduce the amount of medications taken. Interventions by pharmacists certified in palliative pharmacies tended to reduce adverse drug events. Conclusion: This was the first multicenter prospective observational study conducted in Japan to demonstrate hospital pharmacist intervention's effectiveness in promoting appropriate prescription and, consequently, a reduction in the number of medications in use and polypharmacy.

Inappropriate medications and physical function: a systematic review

Background and aims:

Inappropriate medication prescription is highly prevalent in older adults and is associated with adverse health outcomes. The aim of this study was to examine the associations between potentially inappropriate medications (PIMS) and potential prescribing omissions with physical function in older adults situated in diverse environments.

Methods:

A systematic search was completed using the following databases: MEDLINE, CINAHL, PsycINFO, EMBASE and COCHRANE. Results were extracted from the included studies.

Results:

In total, 55 studies reported on 2,767,594 participants with a mean age of 77.1 years (63.5% women). Study designs comprised 26 retrospective cohort studies, 21 prospective cohort studies and 8 cross-sectional studies. Inappropriate medications in community and hospital settings were significantly associated with higher risk of falls (21 out of 30 studies), higher risk of fractures (7 out of 9 studies), impaired activities of daily living (ADL; 8 out of 10 studies) and impaired instrumental ADL (IADL) score (4 out of 6 studies). Five out of seven studies also showed that PIMs were associated with poorer physical performance comprising the Timed Up and Go test, walking speed, grip strength, time to functional recovery, functional independence and scale of functioning. Many medication classes were implicated as PIMs in falls, fractures and impairment in physical performance including antipsychotic, sedative, anti-anxiety, anticholinergic, antidiabetic, opioid and antihypertensive medications. For patients not receiving musculoskeletal medications, such as calcium, vitamin D and bisphosphonates, older adults were found to be at risk of a hospital admission for a fall or fracture.

Conclusion:

Inappropriate medication prescriptions are associated with impaired physical function across longitudinal and cross-sectional studies in older adults situated in diverse settings. It is important to support older people to reduce their use of inappropriate medications and prevent prescribing omissions.

Plain language summary

Inappropriate medications and physical function

Background and aims: The use of inappropriate medications is very common in older adults and is associated with harmful health problems. The aim was to examine associations between potentially inappropriate medications and potential prescribing omissions with physical function in older adults situated in diverse environments. Methods: Library databases were examined for possible studies to include and a systematic search was completed. Relevant information was obtained from the included studies. Results: In total, 55 studies reported on 2,767,594 participants who were an average age of 77.1 years and about 6 out of 10 were women. A variety of different study designs were used. Inappropriate medication prescriptions in community and hospital settings were significantly associated with higher risk of falls (21 out of 30 studies), higher risk of fractures (7 out of 9 studies), problems with activities of daily living (ADL), such as eating, bathing, dressing, grooming, walking and toileting (8 out of 10 studies) and problems with instrumental ADL such as managing medications, house cleaning and shopping (4 out of 6 studies). Five out of seven studies also showed that inappropriate medications were associated with poorer physical performance involving the Timed Up and Go test, walking speed, grip strength, time to functional recovery, functional independence and scale of functioning. Many types of medication classes were shown to be associated with a risk of falls, fractures and problems with physical performance. Omitted medications were also associated with falls and fractures. Conclusion: Inappropriate medication prescriptions are associated with problems relating to physical function. It is important to support older people to reduce their use of inappropriate medications and prevent prescribing omissions.

Assisted Living: Optimal Person-Environment Fit

Assisted living (AL) is a well-established alternative to nursing homes, promoting autonomy and choice in a residential environment. This article examines the opportunities that AL affords for older adults and areas for further research to optimize the fit between resident needs and the AL environment. The model of person-environment fit provides an organizing framework for our commentary. The environment of AL emphasizes choice, independence, and privacy. The acuity of health care needs in AL residents has evolved since its inception. Unlike earlier residents, many today live with multiple chronic conditions and need for functional supports. Regulated by states, there is high variability in oversight, staffing, and resources available in AL. Families play an important role in supporting residents, yet expectations for their engagement may not be clear. Descriptive research abounds but there is a need for more sophisticated approaches to understanding how the AL environment can provide optimal supports for older adults, across all states and across income and racial/ethnic groups. There are several methodological challenges to AL research, including the high variability among AL settings and across states, the lack of common data elements, and difficulty accessing representative samples. With the popularity of AL as an option, it will be important to continue to examine how this environment can evolve to meet the changing needs of the resident population, while balancing the elements of autonomy and affordability.

A nationwide survey of hospital pharmacist interventions to improve polypharmacy for patients with cancer in palliative care in Japan

Background

There is no nationwide data on polypharmacy in palliative care in Japan. In this study, the research committee of the Japanese Society for Pharmaceutical Palliative Care and Sciences conducted an online survey on polypharmacy and inappropriate prescriptions involving its members who worked as hospital pharmacists.

Methods

The online questionnaire included questions about hospital pharmacist interventions for cancer patients who regularly used six or more drugs during a two-month period from October to November 2017.

Results

Of 2618 hospital pharmacists, 359 responded (13.7%). With regard to cancer patients receiving opioids, 40.9 and 22.3% of the respondents replied that percentages of patients prescribed six or more regular medications were “40–69%” and “70–99%,” respectively. Regarding patients on polypharmacy, 73.0% of the respondents reported a low or moderate rate of inappropriate prescriptions, with responses such as “long-term administration of irresponsible or aimless medications”, “adverse drug reactions,” and “duplication of the pharmacological effect”. Furthermore, 24.2, 46.8, and 23.4% of respondents replied that the rates of drug reduction due to pharmacist recommendations were “0”, “1–39%”, and “more than 40%,” respectively. Pharmacist interventions decreased the use of inappropriate medications, including antiemetics, gastrointestinal medications, and hypnotic sedatives, and reduced or prevented adverse drug reactions such as extrapyramidal symptoms, delirium, and sleepiness. Similar results were obtained for cancer patients who did not use opioids. However, the rates of cancer patients on polypharmacy and with reduction of inappropriate medications by pharmacist interventions were significantly higher in cancer patients receiving opioids. Finally, recommendations of board-certified pharmacists in palliative pharmacy contributed to a decrease in the use of inappropriate medications in cancer patients on polypharmacy (p = 0.06).

Conclusion

This nationwide survey clarified pharmacist interventions for polypharmacy in palliative care in Japan. Our data showed frequent polypharmacy in cancer patients receiving opioids, and benefits of pharmacist interventions, especially by board-certified pharmacists in palliative pharmacy, for reducing inappropriate medications and improving adverse drug reactions.
