- Aims The objective of this study is to investigate the association between multiple antihypertensive use and mortality in residents with diagnosed hypertension, and whether dementia and frailty modify this association.Methods This is a two-year prospective cohort study of 239 residents with diagnosed hypertension receiving antihypertensive therapy across six residential aged care services in South Australia. Data were obtained from electronic medical records, medication charts and validated assessments. The primary outcome was all-cause mortality and the secondary outcome was cardiovascular-related hospitalizations. Inverse probability weighted Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality. Covariates included age, sex, dementia severity, frailty status, Charlson's comorbidity index and cardiovascular comorbidities.Results The study sample (mean age of 88.1 +/- 6.3 years; 79% female) included 70 (29.3%) residents using one antihypertensive and 169 (70.7%) residents using multiple antihypertensives. The crude incidence rates for death were higher in residents using multiple antihypertensives compared with residents using monotherapy (251 and 173/1000 person-years, respectively). After weighting, residents who used multiple antihypertensives had a greater risk of mortality compared with monotherapy (HR 1.40, 95%CI 1.03-1.92). After stratifying by dementia diagnosis and frailty status, the risk only remained significant in residents with diagnosed dementia (HR 1.91, 95%CI 1.20-3.04) and who were most frail (HR 2.52, 95%CI 1.13-5.64). Rate of cardiovascular-related hospitalizations did not differ among residents using multiple compared to monotherapy (rate ratio 0.73, 95%CI 0.32-1.67).Conclusions Multiple antihypertensive use is associated with an increased risk of mortality in residents with diagnosed hypertension, particularly in residents with dementia and among those who are most frail.

- Objectives: To investigate the association between polypharmacy and medication regimen complexity with time to first hospitalization, number of hospitalizations, and number of hospital days over a 12-month period. Design: A 12-month prospective cohort study. Participants and Setting: A total of 383 residents of 6 Australian long-term care facilities (LTCFs). Measurements: The primary exposures were polypharmacy (>= 9 regular medications) and the 65-item Medication Regimen Complexity Index (MRCI). Cox proportional hazards regression was used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between polypharmacy and MRCI with time to first hospitalization. Poisson regression was used to compute incident rate ratios (IRR) and 95% CIs for the association between polypharmacy and MRCI with number of hospitalizations and number of hospital days. Models were adjusted for age, sex, length of stay in LTCF, comorbidities, activities of daily living, and dementia severity. Results: There were 0.56 (95% CI 0.49-0.65) hospitalizations per person-year and 4.52 (95% CI 4.31-4.76) hospital days per person-year. In adjusted analyses, polypharmacy was associated with time to first hospitalization (HR 1.84; 95% CI 1.21-2.79), number of hospitalizations (IRR 1.51; 95% CI 1.09-2.10), and hospital days per person-year (IRR 1.39; 95% CI 1.24-1.56). Similarly, in adjusted analyses a 10-unit increase in MRCI was associated with time to first hospitalization (HR 1.17; 95% CI 1.06-1.29), number of hospitalizations (IRR 1.15; 95% CI 1.06-1.24), and hospital days per person-year (IRR 1.19; 95% CI 1.16-1.23). Conclusions: Polypharmacy and medication regimen complexity are associated with hospitalizations from LTCFs. This highlights the importance of regular medication review for residents of LTCFs and the need for further research into the risk-to-benefit ratio of prescribing in this setting.

Tidskriftsartikel (refereegranskat)abstract
- Frailty is a geriatric condition associated with increased vulnerability to adverse drug events and medication-related harm. Existing clinical practice guidelines rarely provide medication management recommendations specific to frail older people. This report presents international consensus principles, generated by the Optimizing Geriatric Pharmacotherapy through Pharmacoepidemiology Network, related to medication management in frail older people. This consensus comprises 7 principles for clinical practice, 6 principles for research, and 4 principles for education. Principles for clinical practice include (1) perform medication reconciliation and maintain an up-to-date medication list; (2) assess and plan based on individual's capacity to self-manage medications; (3) ensure appropriate prescribing and deprescribing; (4) simplify medication regimens when appropriate to reduce unnecessary burden; (5) be alert to the contribution of medications to geriatric syndromes; (6) regularly review medication regimens to align with changing goals of care; and (7) facilitate multidisciplinary communication among patients, caregivers, and healthcare teams. Principles for research include (1) include frail older people in randomized controlled trials; (2) consider frailty status as an effect modifier; (3) ensure collection and reporting of outcome measures important in frailty; (4) assess impact of frailty on pharmacokinetics and pharmacodynamics; (5) encourage frailty research in under-researched settings; and (6) utilize routinely collected linked health data. Principles for education include (1) provide undergraduate and post-graduate education on frailty; (2) minimize low-value care related to medication management; (3) improve health and medication literacy; and (4) incorporate evidence in relation to frailty into clinical practice guidelines. These principles for clinical practice, research and education highlight different considerations for optimizing medication management in frail older people. These principles can be used in conjunction with existing best practice guidelines to help achieve optimal health outcomes for this vulnerable population. Implementation of the principles will require multidisciplinary collaboration between healthcare professionals, researchers, educators, organizational leaders, and policymakers.

- Background: Little is known about the contribution of 'pro re nata' (PRN) medications to overall medication burden in residential aged care services (RACS). Objectives: To determine the frequency of, and factors associated with PRN medication administration in RACS. Measurements: Details of all medications charted for regular or PRN use were extracted from medication charts for 383 residents of 6 Australian RACS. Records of medications administered over a 7 day period were also extracted. Factors associated with PRN medication administration among residents charted >= 1 PRN were determined using multivariate logistic regression. Results: Of the 360 (94%) residents charted >= 1 PRN medication, 99 (28%) were administered PRN medication at least once. The most prevalent PRN medications were analgesics and laxatives. Residents with greater dependence with activities of daily living (ADL) (adjusted odds ratio (aOR) per additional point on Katz ADL scale: 0.80; 95% confidence interval (CI) 0.72-0.89; p < 0.001) and a greater number of regular medications (aOR per additional medication: 1.06; 95% CI 1.00-1.13; p = 0.042) were more likely to be administered PRN medication. Conclusions: Although most residents are charted PRN medications, rates of administration are relatively low, suggesting the contribution of PRNs to medication burden in RACS may be lower than previously thought.

- Medication management is becoming increasingly challenging for older people, and there is limited evidence to guide medication prescribing and administration for people with multimorbidity, frailty, or at the end of life. Currently, there is a lack of clear research priorities in the field of geriatric pharmacotherapy. To address this issue, international experts from 5 research groups in geriatric pharmacotherapy and pharmacoepidemiology research were invited to attend the inaugural Optimizing Geriatric Pharmacotherapy through Pharmacoepidemiology Network workshop. A modified nominal group technique was used to explore and consolidate the priorities for conducting research in this field. Eight research priorities were elucidated: quality of medication use; vulnerable patient groups; polypharmacy and multimorbidity; person-centered practice and research; deprescribing; methodological development; variability in medication use; and national and international comparative research. The research priorities are discussed in detail in this article with examples of current gaps and future actions presented. These priorities highlight areas for future research in geriatric pharmacotherapy to improve medication outcomes in older people.
