Medication use quality and safety in older adults: 2020 update

Improving the quality of medication use and medication safety are important priorities for prescribers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2020. We selected high-quality studies that moved the field of research forward and were not merely replication studies. The chosen articles cover domains related to deprescribing, medication safety, and optimizing medication use. The first study, a noninferiority randomized clinical trial in England, evaluated whether antihypertensive medication reduction is possible without significant changes in systolic blood pressure control or adverse events over the 12-week follow-up (domain: deprescribing). The second study, a prospective cohort study of women at Kaiser Permanente Southern, California, examined the association between bisphosphonate use and atypical femur fracture (domain: medication safety). The third study examined the effectiveness and safety of a multifaceted antimicrobial stewardship and quality improvement initiative in reducing unnecessary antimicrobial use for unlikely cystitis cases in noncatheterized residents in 25 nursing homes across the United States (domain: optimizing medication use). Lastly, the fourth study, a population-based cohort study in the United Kingdom, examined the association of tramadol use with risk of hip fracture (domain: medication safety). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.     

Medication Use Quality and Safety in Older Adults: 2018 Update

Improving the quality of medication use and medication safety is an important priority for prescribers who care for older adults. The objective of this article was to identify key articles from 2018 that address these issues. In addition, we selected four of these articles to annotate, critique, and discuss their broader implications for clinical practice. The first study highlights a cluster‐randomized trial that utilized a pharmacist‐led education‐based intervention delivered to both patients and physicians to deprescribe four types of inappropriate medications (sedative‐hypnotics, first‐generation antihistamines, selective nonsteroidal anti‐inflammatory drugs, and glyburide). The second study, a nested case‐control study using data from within the UK Clinical Practice Research Datalink, examined the association between anticholinergic exposure, overall and by anticholinergic medication class, and dementia risk in 40 770 older adults. The third study, a longitudinal cohort study of 1028 Swedish older adults, examined the association between antihypertensive medications and incident dementia. The last study was a randomized, double‐blind, placebo‐controlled trial that investigated the effect of daily low‐dose aspirin (100 mg) for primary prevention on cardiovascular events and major hemorrhage in 19 144 community‐dwelling older adults. Collectively, this current article provides insight into the pertinent topics of medication use quality and safety in older adults and helps raise awareness about optimal prescribing in older adults.

Medication use quality and safety in older adults: 2022 update

Improving the quality of medication use and medication safety are important priorities for healthcare providers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2022. We selected high-quality studies from an OVID search and hand searching of major high impact journals that advanced the field of research forward. The chosen articles cover domains related to deprescribing, medication safety, and optimizing medication use. The MedSafer Study, a cluster randomized clinical trial in Canada, evaluated whether patient specific deprescribing reports generated by electronic decision support software resulted in reduced adverse drug events in the 30 days post hospital discharge in older adults (domain: deprescribing). The second study, a retrospective cohort study using data from Premier Healthcare Database, examined in-hospital adverse clinical events associated with perioperative gabapentin use among older adults undergoing major surgery (domain: medication safety). The third study used an open-label parallel controlled trial in 39 Australian aged-care facilities to examine the effectiveness of a pharmacist-led intervention to reduce medication-induced deterioration and adverse reactions (domain: optimizing medication use). Lastly, the fourth study engaged experts in a Delphi method process to develop a consensus list of clinically important prescribing cascades that adversely affect older persons' health to aid clinicians to identify, prevent, and manage prescribing cascades (domain: optimizing medication use). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.     

Multidisciplinary Team Deprescribing Intervention for Polypharmacy in Elderly Orthopedic Inpatients: A Propensity Score-matched Analysis of a Retrospective Cohort Study

Objective This study evaluated the effectiveness of a multidisciplinary team deprescribing intervention to reduce polypharmacy and potentially inappropriate medications (PIMs) in elderly orthopedic inpatients. Methods In this single-center retrospective observational study, orthopedic inpatients ≥75 years old and prescribed ≥6 different medications were enrolled as participants. Interventions comprised multidisciplinary team-led polypharmacy screening and suggestions regarding deprescribing any unnecessary medications during hospital stays. The primary outcome was reduction in the mean number of regular medicines and PIMs. Secondary outcomes included falls, delirium, and other adverse events during hospitalization as well as emergency department visits or unplanned hospital admissions within six months after discharge. Results After propensity score matching, 184 patients (intervention group, n=92; control group, n=92) were included in the analysis. The mean patient age was 83 years old. The mean number of prescribed medications and PIMs at admission were similar in both groups. The mean change in the number of regular medicines was -1.4 [standard deviation (SD), 2.3] in the intervention group and +0.2 (SD, 1.8) in the control group (p<0.001). The mean change in the number of PIMs was -0.5 (SD, 0.9) in the intervention group and +0.1 (SD, 0.8) in the control group (p<0.001). In-hospital adverse events other than falls and delirium were significantly less common in the deprescribing intervention group than in the control group. Conclusion Deprescribing intervention by our multidisciplinary team seems to have been effective in reducing the number of prescribed medicines and PIMs in elderly orthopedic inpatients, with some accompanying reduction in certain adverse events.     

Surgical Guidelines for Perioperative Management of Older Adults: What Geriatricians Need to Know

A multidisciplinary panel of experts representing surgery, anesthesia, and geriatrics recently published guidelines for surgeons on the optimal perioperative management of older adults, including recommendations on postoperative recovery and posthospital transitions of care. Geriatricians have an important role in the care for older adults in the preoperative period as older adults consider surgical options and prepare for surgical procedures, during the perioperative period as inpatient consultants, and in the postoperative period as older adults transition to rehabilitation facilities or to home. This article outlines the perioperative surgical guidelines and describes how they apply to the role of the geriatrician in the care of older adults during the perioperative period.     

Association Between Antihypertensive Medication Use and Non-cardiovascular Outcomes in Older Men

Background Antihypertensive drugs are prescribed commonly in older adults for their beneficial cardiovascular and cerebrovascular effects, but few studies have assessed antihypertensive drugs’ adverse effects on non-cardiovascular outcomes in routine clinical practice. Objective To evaluate, among older adults, the association between antihypertensive medication use and physical performance, cognition, and mood. Design and Setting Prospective cohort study in a Veterans Affairs primary care clinic, with patients enrolled in 2000–2001 and assessed for medication use, comorbidities, health behaviors, and other characteristics; and followed-up 1 year later. Participants 544 community-dwelling hypertensive men over age 65 years. Measurements Timed chair stands; Trail Making Test part B; and Centers for Epidemiologic Studies Depression (CES-D) scores. Results Participants had a mean age of 74.4 ± 5.2 years and took a mean of 2.3 ± 1.2 antihypertensive medications at baseline. After adjustment for age, comorbidities, level of blood pressure, and other confounders, each 1-unit increase in antihypertensive medication “intensity” was associated with a 0.11-second (95% confidence interval, 0.05–0.16) increase in the time required to complete the timed chair stands. No significant relationship was found between antihypertensive medication intensity and outcomes for Trail Making B or CES-D scores. Conclusions A higher cumulative exposure to antihypertensive medications in community-living older men was associated with adverse effects on physical performance, but not on the cognitive or depression measures available in this study. Clinicians should consider non-cardiovascular related adverse effects when treating older males taking multiple antihypertensive medications.     

Enhancing the Quality of Prescribing Practices for Older Veterans Discharged from the Emergency Department (EQUiPPED): Preliminary Results from Enhancing Quality of Prescribing Practices for Older Veterans Discharged from the Emergency Department,a Novel Multicomponent Interdisciplinary Quality Improvement Initiative

Suboptimal medication prescribing for older adults has been described in a number of emergency department (ED) studies. Despite this, few studies have examined ED‐targeted interventions aimed at reducing the use of potentially inappropriate medications (PIMs). Enhancing Quality of Prescribing Practices for Older Veterans Discharged from the ED (EQUiPPED) is an ongoing multicomponent, interdisciplinary quality improvement initiative in eight Department of Veterans Affairs EDs. The project aims to decrease the use of PIMs, as identified by the Beers criteria, prescribed to veterans aged 65 and older at the time of ED discharge. Interventions include provider education; informatics‐based clinical decision support with electronic medical record–embedded geriatric pharmacy order sets and links to online geriatric content; and individual provider education including academic detailing, audit and feedback, and peer benchmarking. Poisson regression was used to compare the number of PIMs that staff providers prescribed to veterans aged 65 and older discharged from the ED before and after the initiation of the EQUiPPED intervention. Initial data from the first implementation site show that the average monthly proportion of PIMs that staff providers prescribed was 9.4 ± 1.5% before the intervention and 4.6 ± 1.0% after the initiation of EQUiPPED (relative risk = 0.48, 95% confidence interval = 0.40–0.59, P < .001). Preliminary evaluation demonstrated a significant and sustained reduction of ED‐prescribed PIMs in older veterans after implementation of EQUiPPED. Longer follow‐up and replication at collaborating sites would allow for an assessment of the effect on health outcomes and costs.     

Measuring the Quality of Medication Use in Older Adults

The quality of health care in the United States continues to fall short of expectations. A contributing factor is the suboptimal use of medications, a problem that is causing significant morbidity and mortality and costing the healthcare industry billions of dollars each year. Older adults are especially vulnerable to suboptimal quality medication use because of their concurrent medical conditions, multiple medications, and the physiological effects of aging on the use of drug therapy. In addition, older adults and their caregivers are often responsible for managing complex medication regimens. Efforts to measure the quality of medication use in older adults have traditionally focused on inappropriate medications and doses, select indicators of medication appropriateness, or diseases rather than the unique medication needs of individual patients. The goal is to move toward a measure that can account for the complexities of an individual's medication regimen and that is responsive to individual patient values and needs. The purpose of this article is to discuss the benefits and limitations of current strategies to measure the quality of medication use in older adults and, using a case study, illustrate the variations in quality measurement using existing measures. The article concludes with recommendations for moving toward a more-comprehensive approach to measuring the quality of medication use in older adults.     

American Geriatrics Society 2015 Updated Beers Criteria for Potentially Inappropriate Medication Use in Older Adults

The 2015 American Geriatrics Society (AGS) Beers Criteria are presented. Like the 2012 AGS Beers Criteria, they include lists of potentially inappropriate medications to be avoided in older adults. New to the criteria are lists of select drugs that should be avoided or have their dose adjusted based on the individual's kidney function and select drug–drug interactions documented to be associated with harms in older adults. The specific aim was to have a 13‐member interdisciplinary panel of experts in geriatric care and pharmacotherapy update the 2012 AGS Beers Criteria using a modified Delphi method to systematically review and grade the evidence and reach a consensus on each existing and new criterion. The process followed an evidence‐based approach using Institute of Medicine standards. The 2015 AGS Beers Criteria are applicable to all older adults with the exclusion of those in palliative and hospice care. Careful application of the criteria by health professionals, consumers, payors, and health systems should lead to closer monitoring of drug use in older adults.
