Suitable Use of Injectable Agents to Overcome Hypoglycemia Risk, Barriers, and Clinical Inertia in Community-Dwelling Older Adults with Type 2 Diabetes Mellitus Abstract The management of type 2 diabetes mellitus in older adults requires a comprehensive understanding of the relationship between the disease (medical) and the functional, psychological/cognitive, and social geriatric domains, to individualize both glycemic targets and therapeutic approaches. Prevention of hypoglycemia is a major priority that should be addressed as soon as its presence or risk is detected, adjusting the target and therapeutics accordingly. Nonetheless, treatment intensification should not be neglected when applicable, consistent with recommendations from organizations such as the American Geriatrics Society and the American Diabetes Association, to reduce not only long-term macrovascular and microvascular complications (individualization), but also short-term complications from hyperglycemia (polyuria, volume depletion, urinary incontinence). Such complications can negatively impact the physical and cognitive function of older adults, worsen their quality of life, and additionally affect their families and society. We emphasize individualization, utilizing the multiple classes of antihyperglycemic agents available. Metformin remains as first-line therapy, and additional agents offer advantages and disadvantages that ought to be considered when developing a patient-centric plan of care. For selected cases, injectable therapies such as long-acting basal insulin analogs and glucagon-like peptide-1 receptor agonists can offer advantages to counter hypoglycemia risk, patient-related barriers, and clinical inertia. Furthermore, some injectable agents could potentially simplify regimens while providing safe and effective glycemic control. In this review, we discuss the use of injectable therapies for selected community-dwelling older adults, barriers to transition to injectable therapy, and measures aimed at removing these barriers and assisting physicians and their teams to transition older patients to injectable therapies when appropriate.

Blockade of Renin–Angiotensin–Aldosterone System in Elderly Patients with Heart Failure and Chronic Kidney Disease: Results of a Single-Center, Observational Cohort Study Abstract Background Angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEis/ARBs) and mineralocorticoid receptor antagonists (MRAs) have been shown to benefit patients with heart failure with reduced ejection fraction (HFrEF). However, there is a lack of information on the advantages of these drugs for patients with chronic kidney disease (CKD), and this gap is especially pronounced in elderly patients. Objective The objective of this study was to assess the role of treatment consisting of ACEi/ARBs and MRAs in patients ≥ 75 years of age with CKD. Methods From January 2008 to July 2014, 390 consecutive patients ≥ 75 years of age with an ejection fraction ≤ 35% and a glomerular filtration rate (GFR) ≤ 60 mL/min/1.73 m2 were included. We analyzed the relationship between treatment with ACEi/ARBs and MRAs and mortality or cardiovascular events. Results Three hundred and ninety patients were included, with a mean age of 82.6 ± 4.1 years. Mean ejection fraction was 27.9 ± 6.5%. Renal dysfunction was mild (GFR 45–60 mL/min/1.73 m2) in 50.3% of patients, moderate (GFR 30–44 mL/min/1.73 m2) in 37.4%, and severe (GFR < 30 mL/min/1.73 m2) in 12.3%. After 32 ± 23 months, 68.7% of patients were receiving ACEi/ARBs and 40% were receiving MRAs; 65.9% developed a cardiovascular event and 54.4% had died. After multivariate Cox regression analysis, ACEi/ARB treatment was independently associated with a decreased rate of cardiovascular events (hazard ratio 0.71 [95% confidence interval 0.50–0.98]) and MRAs were not associated with a decrease in cardiovascular events or total mortality. Conclusions Treatment with ACEi/ARBs in elderly patients with HFrEF and CKD was associated with a lower rate of cardiovascular events, though MRA treatment failed to reduce the risk of morbidity and mortality in our population.

Pharmacological Management of Osteoporosis in Rheumatoid Arthritis Patients: A Review of the Literature and Practical Guide Abstract Rheumatoid arthritis (RA) is a chronic disabling disease that is associated with increased localized and generalized osteoporosis (OP). Previous studies estimated that approximately one-third of the RA population experience bone loss. Moreover, RA patients suffer from a doubled fracture incidence depending on several clinical factors, such as disease severity, age, glucocorticoid (GC) use, and immobility. As OP fractures are related to impaired quality of life and increased mortality rates, OP has an enormous impact on global health status. Therefore, there is an urgent need for a holistic approach in daily clinical practice. In other words, both OP- and RA-related factors should be taken into account in treatment guidelines for OP in RA. First, to determine the actual fracture risk, dual-energy X-ray absorptiometry (DXA), including vertebral fracture assessment (VFA) and calculation of the 10-year fracture risk with FRAX®, should be performed. In case of high fracture risk, calcium and vitamin D should be supplemented alongside anti-osteoporotic treatment. Importantly, RA treatment should be optimal, aiming at low disease activity or remission. Moreover, GC treatment should be at the lowest possible dose. In this way, good fracture risk management will lead to fracture risk reduction in RA patients. This review provides a practical guide for clinicians regarding pharmacological treatment options in RA patients with OP, taking into account both osteoporotic-related factors and factors related to RA.

Does Deprescribing Improve Quality of Life? A Systematic Review of the Literature Abstract Background Deprescribing has been shown to reduce potentially inappropriate or unnecessary medications; however, whether these benefits translate into improved quality of life (QOL) is uncertain. Objective The objective of this study was to isolate the impact of deprescribing on patient or designated representative reported QOL; satisfaction with care (SWC) and emergency department (ED) visits and hospitalizations were also investigated to further explore this question. Methods This systematic review searched the Cochrane Library, Cumulative Index to Nursing and Allied Health (CINAHL), MEDLINE, and EMBASE from database inception until November 2017. Randomized controlled trials and non-randomized prospective studies of older adults (> 65 years or older) and older persons with life-limiting conditions were included. Two reviewers independently assessed the search results and performed risk of bias assessments. Data on QOL, SWC, and ED visits and hospitalizations were extracted from all identified studies. Risk of bias of individual studies was assessed using measures recommended by the Cochrane Collaboration. Results Screening of 6543 eligible records identified 12 studies within 13 articles. In ten studies investigating the reduction of at least one medication deprescribed, compared with usual care, all but two found no difference in QOL. To date there has only been one study examining the impact of deprescribing on SWC, which was found to be not statistically significant. Four studies exploring the impact of deprescribing on ED visits and hospitalizations also found no significant difference. However, many studies were found to have a higher performance, detection, or other bias. We found considerable heterogeneity in patient populations, targeted medications for deprescribing, and QOL measurements used in these studies. Conclusion Based on a limited number of studies with varying methodological rigor, deprescribing may not significantly improve QOL or SWC; however, it may not contribute to additional ED visits and hospitalizations. Future controlled studies are needed.

Patients’ Attitudes Towards Deprescribing Alpha-Blockers and Their Willingness to Participate in a Discontinuation Trial Abstract Objective The objective of this study was to gain insights into the attitudes of men with lower urinary tract symptoms towards deprescribing alpha-blockers and to assess their willingness to participate in a planned discontinuation trial. Methods This was a cross-sectional questionnaire study. Men aged 30 years and older with lower urinary tract symptoms, who were first prescribed an alpha-blocker in 2015 or 2016, were selected from a population-based prescription database. We recorded lower urinary tract symptom severity (e.g., International Prostate Symptom Score and Overactive Bladder questionnaire) and patient characteristics (e.g., comorbidity and polypharmacy). The linguistically validated Dutch version of the revised Patients’ Attitudes Towards Deprescribing (rPATD) questionnaire was also used, to which we added ten specific questions on attitudes towards the deprescribing of alpha-blockers. Information about a future discontinuation trial on alpha-blockers was then provided and participants were asked to indicate if they would participate. We explored the explanatory factors for the willingness to participate by logistic regression analyses. Results Of the 1380 patients in the database, 421 were using an alpha-blocker, and 195 completed the questionnaire. Of these, 16 men were excluded because of indwelling catheter use or unknown indication. The mean age of the 179 participants was 69.4 (standard deviation 9.2) years. Most men were satisfied with their current therapy, but almost all (93%) were willing to stop the medicine at the request of a doctor. Therefore, most men (61%) were willing to participate in the proposed alpha-blocker discontinuation trial. Willingness to stop therapy was affected by patients’ perceptions of the appropriateness of alpha-blocker therapy and concerns about stopping that therapy. Conclusions Although men who use alpha-blockers are generally satisfied with their current therapy, most will participate in a discontinuation trial.

Management of Gastroesophageal Reflux Disease in the Elderly Patient Abstract Gastroesophageal reflux disease (GERD) is an especially common disorder in the elderly population. Its presentation in this population is often different from that in younger patients. A greater proportion of patients experience atypical GERD symptoms rather than heartburn or regurgitation, increasing the likelihood the diagnosis will be missed or overlooked. Elderly patients more commonly present with severe erosive esophagitis and GERD complications compared with younger patients, and thus may require more aggressive therapy. While diagnostic work-up and management of GERD in elderly patients is similar to the general population and primarily involves acid suppression with endoscopic and surgical techniques reserved for refractory cases, there are many important considerations that are particular to the elderly.

Assessing the Importance of Factors Associated with Cost-Related Nonadherence to Medication for Older US Medicare Beneficiaries Abstract Background Prescription drug costs have been rising rapidly in the USA, contributing to the persistent problem of cost-related medication nonadherence (CRN) among older Medicare beneficiaries. Given the importance of CRN and the negative outcomes associated with it, it is important to examine the factors that affect CRN. This study aims to estimate the factors influencing CRN among older Medicare beneficiaries and to rank their relative contribution in explaining CRN. Methods We used a 2015 Medicare Current Beneficiary Survey linked to Medicare claims data to identify older Medicare beneficiaries aged 65 years and over. Multivariate logistic regression was performed to identify factors associated with CRN. Factors included in the regression analyses were based on a conceptual framework adapted from Piette et al., including main effects (financial factors and regimen complexity) and contextual factors (sociodemographic, lifestyle and health factors). Dominance analysis was conducted to determine their relative importance in predicting CRN. Results Our study sample included 4427 older Medicare beneficiaries, 13.43% of whom reported CRN. For main effects, drug coverage and regimen complexity were significantly associated with CRN. Compared to beneficiaries with public coverage, those with private drug coverage were less likely to report CRN while those without drug coverage were more likely to report CRN. Having more than two monthly prescriptions was also associated with higher CRN. Significant contextual factors included age, activities of daily living limitations, perceived health status, cancer, rheumatoid arthritis, non-rheumatoid arthritis, depression, and lung disease. Dominance analysis showed drug coverage was the most influential factor in explaining CRN, after which age, ADL limitations, and depression ranked in sequence. Conclusions These findings can help policy makers understand the relative importance of factors affecting CRN and identify the most important areas for intervention to improve CRN.

Reducing Inappropriate Drug Use in Older Patients by Use of Clinical Decision Support in Community Pharmacy: A Mixed-Methods Evaluation Abstract Introduction Older people are prone to drug-related harm. Clinical decision support systems (CDSSs) in community pharmacies may improve appropriate prescribing in this population. Objective This study investigated (persistent) drug therapy changes and its determinants to reduce potentially inappropriate medication (PIM) in older patients based on CDSS alerts and to investigate barriers and facilitators for implementation of drug therapy changes based on these CDSS alerts. Methods Five clinical decision rules based on national guidelines for inappropriate drugs in older patients were incorporated in a web-based CDSS in 31 community pharmacies between February and April 2017. The CDSS generated alerts for patients aged > 70 years who had prescriptions for one of the following drugs: alprazolam, amitriptyline, barnidipine, duloxetine, fluoxetine, trazodone, quetiapine and olanzapine. The registered alert management data and medication dispensing histories were analysed to find potential determinants of persistent drug therapy changes. Ten pharmacists were interviewed about the barriers and facilitators for implementing drug therapy changes based on CDSS alerts. An inductive thematic analysis of the transcripts was performed. Results The pharmacists recorded the management of 1810 of the 2589 generated alerts, and 158 (8.7%) alerts were associated with a persistent drug therapy change. A logistic regression analysis found that the drug triggering the alert and the type of prescription [first dispensing vs. repeat; odds ratio 2.1 (95% confidence interval 1.4–3.2)] were significantly associated with persistent drug therapy changes. No association was found between persistent changes and age, sex, number of medicines in use, or recent clinical medication review. Analysis of the interviews revealed nine barriers and facilitators associated with drug therapy change. Conclusion When community pharmacists implemented CDSS alerts to reduce inappropriate drug use in older patients, they registered a persistent drug therapy change in 8.7% of the cases. Alerts triggered by a first prescription were two times more likely to be associated with a persistent drug therapy change than alerts triggered by repeat prescriptions. This study found that clinical rules can be used to detect inappropriate drug use in older patients and that drug therapy can change based on the alerts. This suggests that CDSS alerts are a useful tool for implementing guidelines on PIM in older patients in daily practice.

Frequency and Predictors of Polypharmacy in US Medicare Patients: A Cross-Sectional Analysis at the Patient and Physician Levels Abstract Background Polypharmacy in older patients increases the risk of medication-related adverse events and can be a marker of unnecessary care. Objectives The aim of this study was to describe the frequency of polypharmacy among patients 65 years of age or older and identify factors associated with the occurrence of patient-level and physician-level polypharmacy. Methods We performed a cross-sectional analysis of 100% Medicare claims data from January 1, 2016 to December 31, 2016. All patients with continuous Medicare coverage (Parts A, B, and D) throughout 2016 who were 65 years of age or older and who were prescribed at least one medication for at least 30 days were included in the analysis. Each patient was attributed to the primary care physician who prescribed them the most medications. Physicians treating fewer than ten patients were excluded. We defined polypharmacy based on the highest number of concurrent medications at any point during the year. We used hierarchical linear regression to study patient- and physician-level characteristics associated with high prescribing rates. Results We identified 25,747,560 patients attributed to 147,879 primary care physicians. The patient-level mean [standard deviation (SD)] concurrent medication rate was 5.6 (3.3), and the physician-level mean (SD) was 5.6 (1.1). A total of 6108 physicians (4.1% of sample) had a mean concurrent number of medications greater than two SDs above the physician-level mean. At the patient level in the adjusted model, a history of HIV/AIDS, diabetes mellitus, solid organ transplant, and systolic heart failure were the comorbidities most strongly associated with polypharmacy. The relative difference in number of medications associated with these comorbidities were 1.89, 1.39, 1.32, and 1.06, respectively. At the physician level, increased time since medical school graduation and smaller practice size were associated with lower rates of polypharmacy. Conclusions Patterns of high prescribing to older patients is common and measurable at the physician level. Addressing high outlier prescribers may represent an opportunity to reduce avoidable harm and excessive costs.
