Pharmacotherapy in the heart transplant recipient: A primer for nurse clinicians and pharmacists.

Heart transplantation (HT) is the definitive treatment for eligible patients with end-stage heart disease. A major complication of HT is allograft rejection which can lead to graft dysfunction and death. The guiding principle of chronic immunosuppression therapy is to prevent rejection of the transplanted organ while avoiding oversuppression of the immune system, which can cause opportunistic infections and malignancy. The purpose of this review is to describe immunosuppressive management of the HT recipient-including agent-specific pharmacology and pharmacokinetics, outcomes data, adverse effects, clinical considerations, and recent guideline updates. We will also provide recommendations for medical prophylaxis of immunosuppressed patients based on the most recent clinical guidelines. Additionally, we highlight the importance of medical therapy adherence and the effect of social determinants of health on the long-term management of HT. HT recipients are a complex and high-risk population. The objective of this review is to describe basic pharmacotherapy in HT and implications for nurses and pharmacists.

The Clinical Conundrum of Cannabis: Current Practices and Recommendations for Transplant Clinicians: An Opinion of the Immunology/Transplantation PRN of the American College of Clinical Pharmacy.

Cannabis, or marijuana, comprises many compounds with varying effects. It has become a treatment option for chronic diseases and debilitating symptoms, and evidence suggests that it has immunomodulatory and antiinflammatory properties. Transplant centers are more frequently facing issues about cannabis, as indications and legalization expand. As of February 2020, 33 states and the District of Columbia have legalized medical cannabis, and 14 have legalized recreational cannabis. Moreover, 8 states have passed legislation prohibiting the denial of transplant listing solely based on cannabis use. Studies demonstrate the potential for significant pharmacokinetic and pharmacodynamic interactions between cannabis and immunosuppression. Additionally, safety concerns include increased risk of myocardial infarction, ischemic stroke, tachyarrhythmias, malignancy, neurocognitive deficits, psychosis, other neuropsychiatric disorders, cannabis use disorder, respiratory symptoms, and infection. A recent retrospective database study found a negative association between documented cannabis use disorder and graft survival, but little additional evidence exists evaluating this relationship. In the absence of robust clinical data, transplant centers need a clear, reasoned, and systematic approach to cannabis. The results of our national survey, unfortunately, found little consensus among institutions. As both recreational and medicinal cannabis become more ubiquitous nationwide, transplant centers will need to develop comprehensive policies to address its use.

Report from the 2018 consensus conference on immunomodulating agents in thoracic transplantation: Access, formulations, generics, therapeutic drug monitoring, and special populations.

In 2009, the International Society for Heart and Lung Transplantation recognized the importance and challenges surrounding generic drug immunosuppression. As experience with generics has expanded and comfort has increased, substantial issues have arisen since that time with other aspects of immunomodulation that have not been addressed, such as access to medicines, alternative immunosuppression formulations, additional generics, implications on therapeutic drug monitoring, and implications for special populations such as pediatrics and older adults. The aim of this consensus document is to address critically each of these concerns, expand on the challenges and barriers, and provide therapeutic considerations for practitioners who manage patients who need to undergo or have undergone cardiothoracic transplantation.

The impact of drug shortages on patients with cardiovascular disease: causes, consequences, and a call to action.

Shortages of cardiovascular drugs have become increasingly common, representing an ongoing public health crisis. Given few therapeutic alternatives to many of the drugs in short supply, these shortages also pose a major challenge for cardiovascular care professionals. Although changes in the regulatory environment have led to some improvements in recent years, problems involving manufacturing processes remain the most common underlying cause. Because of the complex nature of drug shortages, sustainable solutions to prevent and mitigate them will require collaboration between regulatory agencies, drug manufacturers, and other key stakeholder groups. In this report, we describe the scope of the cardiovascular drug shortage crisis in the United States, including its underlying causes and the efforts currently being made to address it. Furthermore, we provide specific recommendations for how cardiovascular care professionals can be involved in efforts to limit the impact of drug shortages on patient care as well as policy changes aimed at preventing and mitigating them.

The cost of inpatient death associated with acute coronary syndrome.

BACKGROUND: No studies have addressed the cost of inpatient mortality during an acute coronary syndrome (ACS) admission. OBJECTIVE: Compare ACS-related length of stay (LOS), total admission cost, and total admission cost by day of discharge/death for patients who died during an inpatient admission with a matched cohort discharged alive following an ACS-related inpatient stay. METHODS: Medical and pharmacy claims (2009-2012) were used to identify admissions with a primary diagnosis of ACS from patients with at least 6 months of continuous enrollment prior to an ACS admission. Patients who died during their ACS admission (deceased cohort) were matched (one-to-one) to those who survived (survived cohort) on age, sex, year of admission, Chronic Condition Index score, and prior revascularization. Mean LOS, total admission cost, and total admission cost by the day of discharge/death for the deceased cohort were compared with the survived cohort. A generalized linear model with log transformation was used to estimate the differences in the total expected incremental cost of an ACS admission and by the day of discharge/death between cohorts. A negative binomial model was used to estimate differences in the LOS between the two cohorts. Costs were inflated to 2013 dollars. RESULTS: A total of 1,320 ACS claims from patients who died (n=1,320) were identified and matched to 1,319 claims from the survived patients (n=1,319). The majority were men (68%) and mean age was 56.7±6.4 years. The LOS per claim for the deceased cohort was 47% higher (adjusted incidence rate ratio: 1.47, 95% confidence interval: 1.37-1.57) compared with claims from the survived cohort. Compared with the survived cohort, the adjusted mean incremental total cost of ACS admission claims from the deceased cohort was US$43,107±US$3,927 (95% confidence interval: US$35,411-US$50,803) higher. CONCLUSION: Despite decreasing ACS hospitalizations, the economic burden of inpatient death remains high.

Risk Factors of Prescription Opioid Overdose Among Colorado Medicaid Beneficiaries.

UNLABELLED: This study aims to determine risk factors of opioid overdose among the Colorado Medicaid population. A retrospective nested case-control study was undertaken. Medicaid beneficiaries who had ≥1 medical claim for an emergency department visit or a hospitalization associated with an opioid overdose from July 2009 to June 2014 were defined as cases. Controls were selected using a nearest neighbor matching without replacement. The matched controls were selected on the basis of age, sex, and opioid prescription. One case was matched with three controls. Multivariate conditional logistic regression was used to compare risk factors. A total of 816 cases with 2,448 controls were included. Six factors were associated with opioid overdose: mean morphine dose equivalent (>50 mg/d; odds ratio [OR] = 1.986 [95% confidence interval [CI], 1.509-2.614]), methadone use (switching opioid to methadone vs. no methadone use; OR = 7.230 [95% CI, 2.346-22.286]), drug/alcohol abuse (OR = 3.104 [95% CI, 2.195-4.388]), other psychiatric illness (OR = 1.730 [95% CI, 1.307-2.291]), benzodiazepine use (OR = 2.005 [95% CI, 1.516-2.652]), and the number of pharmacies used by the beneficiary (≥4 pharmacies vs. 1 pharmacy; OR = 1.514 [95% CI, 1.003-2.286]). In conclusion, several factors are associated with opioid overdose. States and communities should ensure the availability of at-home intranasal naloxone for overdose rescue on the basis of the presence of risk factors. PERSPECTIVE: This article presents the risk factors of opioid overdose among the Colorado Medicaid population. On the basis of study findings, Colorado Medicaid is currently working with physicians, hospitals, and other health system stakeholders to continue to develop policies to identify and assist this subset of our population. One such policy will be to provide at-home intranasal naloxone for overdose rescue.

Impact of a Telehealth and Care Management Program on All-Cause Mortality and Healthcare Utilization in Patients with Heart Failure.

BACKGROUND: Telehealth has the potential to improve chronic disease management and outcomes, but data regarding direct benefit of telehealth in patients with heart failure (HF) have been mixed. The objective of this study was to determine whether the Health Buddy Program (HBP) (Bosch Healthcare, Palo Alto, CA), a content-driven telehealth system coupled with care management, is associated with improved outcomes in Medicare beneficiaries with HF. MATERIALS AND METHODS: This was a retrospective cohort study of 623 Medicare beneficiaries with HF offered HBP enrollment compared with a propensity score-matched control group of Medicare beneficiaries with HF from the Medicare 5% sample. Associations between availability of the HBP and all-cause mortality, hospitalization, hospital days, and emergency department visits were evaluated. RESULTS: Beneficiaries offered enrollment in the HBP had 24.9% lower risk-adjusted all-cause mortality over 3 years of follow-up (hazard ratio [HR] = 0.75; 95% confidence interval [CI], 0.63-0.89; p = 0.001). Patients who used the HBP at least once (36.9%) had 57.2% lower mortality compared with matched controls (HR = 0.43; 95% CI, 0.31-0.60; p < 0.001), whereas patients who did not use the HBP had no significant difference in survival (HR = 0.96; 95% CI, 0.78-1.19; p = 0.69). Patients offered the HBP also had fewer hospital admissions following enrollment (Δ = -0.05 admissions/quarter; p = 0.011), which was primarily observed in patients who used the HBP at least once (Δ = -0.10 admissions/quarter; p < 0.001). CONCLUSIONS: The HBP, a content-driven telehealth system coupled with care management, was associated with significantly better survival and reduced hospitalization in Medicare beneficiaries with HF. Prospective study is warranted to determine the mechanism of this association and opportunities for optimization.

Comparative Effectiveness of Ranolazine Versus Traditional Therapies in Chronic Stable Angina Pectoris and Concomitant Diabetes Mellitus and Impact on Health Care Resource Utilization and Cardiac Interventions.

Comparative studies evaluating traditional versus newer antianginal (AA) medications in chronic stable angina pectoris (CSA) on cardiovascular (CV) outcomes and utilization are limited, particularly in patients with diabetes mellitus (DM). Claims data (2008 to 2012) were analyzed using a commercial database. Patients with CSA receiving a ß blocker (BB), calcium channel blocker (CCB), long-acting nitrate (LAN), or ranolazine were identified and followed for 12 months after a change in AA therapy. Patients on traditional AA medications were required to have concurrent sublingual nitroglycerin. Therapy change was defined as adding or switching to another traditional AA medication or ranolazine to identify patients whose angina was inadequately controlled with previous therapy. Four groups were identified (BB, CCB, LAN, or ranolazine users) and matched on relevant characteristics. A DM subset was identified. Logistic regression compared revascularization at 30, 60, 90, 180, and 360 days. Negative binomial regression compared all-cause, CV-, and DM-related (in the DM cohort) health care utilization. A total of 8,008 patients were identified with 2,002 patients in each matched group. Majority were men (mean age 66 years). A subset of 3,724 patients with DM (BB, n = 933; CCB, n = 940; LAN, n = 937; and ranolazine, n = 914) resulted from this cohort. Compared to ranolazine in the overall cohort, traditional AA medication exhibited greater odds for revascularization and higher rates in all-cause outpatient, emergency room visits, inpatient length of stay, and CV-related emergency room visits. In the DM cohort, ranolazine demonstrated similar benefits over traditional AA medication. In conclusion, ranolazine use in patients with inadequately controlled chronic angina is associated with less revascularization and all-cause and CV-related health care utilization compared to traditional AA medication.

One-year post-discharge resource utilization and treatment patterns of patients with acute coronary syndrome managed with percutaneous coronary intervention and treated with ticagrelor or prasugrel.

OBJECTIVE: Our objective was to compare 1-year real-world healthcare resource utilization (HRU), associated charges, and antiplatelet treatment patterns among patients with acute coronary syndrome (ACS) managed with percutaneous coronary intervention (PCI) and treated with ticagrelor or prasugrel. METHODS: Using the ProMetis-Lx database, adult ACS-PCI patients treated with ticagrelor or prasugrel post-discharge were identified between 1 August 2011 and 31 May 2013 and propensity matched to adjust for baseline differences. RESULTS: Before matching, ticagrelor-treated patients (n = 2991) were older with increased baseline ischemic and bleeding risks compared with prasugrel-treated patients (n = 12,797). After matching, ticagrelor patients had higher all-cause HRU (2.5 vs. 2.4 per patient per month; P = 0.012) and cardiovascular (CV) HRU (0.4 vs. 0.3 per patient per month; P = 0.026), with the difference in CV rehospitalizations (17.7 vs. 15.7 %; P = 0.011) primarily driven by congestive heart failure (CHF) (4.9 vs. 3.8 %; P = 0.02). All-cause charges within 1 year did not significantly differ between groups ($US5456 vs. 4844 per patient per month; P = 0.37), but dyspnea-related total charges were significantly higher with ticagrelor ($US139 vs. 95 per patient per month; P = 0.005). Although infrequent, switching was slightly higher with ticagrelor (8.3 vs. 6.0 %; P < 0.001) at 1 year, and mean persistence was slightly longer with prasugrel (150 vs. 159 days; P = 0.002), with no significant difference in mean adherence (61 vs. 63 %; P = 0.17). CONCLUSION: Overall monthly HRU was slightly lower with prasugrel than with ticagrelor, with no significant difference in bleeding HRU. Prasugrel was associated with slightly higher pharmacy charges, but lower dyspnea charges, resulting in no significant difference in total charges. Patients receiving prasugrel tended to use it for longer than those receiving ticagrelor as less switching occurred. These findings may aid decision making, but must be tempered due to inherent study limitations.

Indirect and direct costs of acute coronary syndromes with comorbid atrial fibrillation, heart failure, or both.

BACKGROUND: The objective of this study was to determine the direct and indirect costs of acute coronary syndromes (ACS) alone and with common cardiovascular comorbidities. METHODS: A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF), ACS with heart failure (HF), and ACS with both conditions. Direct costs were calculated for all-cause and cardiovascular-related health care resource utilization. Indirect costs were determined from productivity losses from missed days of work. Regression analysis was developed for each outcome controlling for age, US census region, insurance coverage, sex, race, ethnicity, education attainment, family income, and comorbidity burden. A negative binomial regression model was used for health care utilization variables. A Tobit model was utilized for health care costs and productivity loss variables. RESULTS: Total health care costs were greatest for those with ACS and both AF and HF ($38,484±5,191) followed by ACS with HF ($32,871±2,853), ACS with AF ($25,192±2,253), and ACS only ($17,954±563). Compared with the ACS only cohort, the mean all-cause adjusted health care costs associated with ACS with AF, ACS with HF, and ACS with AF and HF were $5,073 (95% confidence interval [CI] 719-9,427), $11,297 (95% CI 5,610-16,985), and $15,761 (95% CI 4,784-26,738) higher, respectively. Average wage losses associated with ACS with and without AF and/or HF amounted to $5,266 (95% CI -7,765, -2,767), when compared with patients without these conditions. CONCLUSION: ACS imposes a significant economic burden at both the individual and society level, particularly when with comorbid AF and HF.

Hidden costs associated with venous thromboembolism: impact of lost productivity on employers and employees.

OBJECTIVE: To determine productivity loss and indirect costs with deep vein thrombosis (DVT) and pulmonary embolism (PE). METHODS: Medical and pharmacy claims with short-term disability (STD) and long-term disability (LTD) claims from 2007 to 2010 were analyzed from the Integrated Benefits Institute's Health and Productivity Benchmarking (IBI-HPB) database (STD and LTD claims) and IMS LifeLink™ data (medical and pharmacy claims), which were indirectly linked using a weighting approach matching from IBI-HPB patients' demographic distribution. RESULTS: A total of 5442 DVT and 6199 PE claims were identified. Employees with DVT lost 57 STD and 440 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7414 and $58181, respectively. Employees with PE lost 56 STD and 364 LTD days per disability incident. The average per claim productivity loss from STD and LTD was $7605 and $48,751, respectively. CONCLUSIONS: Deep vein thrombosis and PE impose substantial economic burdens.

The economic burden of acute coronary syndromes for employees and their dependents: medical and productivity costs.

OBJECTIVE: To determine the total burden of illness, including direct and indirect costs for employees and their dependents with acute coronary syndrome (ACS). METHODS: Medical and pharmacy claims along with short-term disability (STD) and long-term disability (LTD) claims from 2007 to 2010 were analyzed using two data sets: Integrated Benefits Institute's Health and Productivity Benchmarking Database (STD and LTD claims) and IMS LifeLink™ Health Plan Data (medical and pharmacy claims). RESULTS: Employees with ACS lost 60.2 ± 0.29 STD and 397.9 ± 8.09 LTD days per disability incident. For employers, the estimated average per claim productivity loss from STD and LTD was $7943 ± 39.7 and $52,473 ± 1114, respectively. Total annual ACS health care costs per employee were $8170 ± 106, with $7545 ± 104 for annual medical costs. Hospitalizations accounted for 75% of total annual ACS health care costs. CONCLUSIONS: ACS imposes a substantial economic burden on employees, employers, and society.

Clinical pharmacy services in heart failure: an opinion paper from the Heart Failure Society of America and American College of Clinical Pharmacy Cardiology Practice and Research Network.

BACKGROUND: Heart failure (HF) care takes place in multiple settings, with a variety of providers, and generally involves patients who have multiple comorbidities. This situation is a "perfect storm" of factors that predispose patients to medication errors. METHODS AND RESULTS: The goals of this paper are to outline potential roles for clinical pharmacists in a multidisciplinary HF team, to document outcomes associated with interventions by clinical pharmacists, to recommend minimum training for clinical pharmacists engaged in HF care, and to suggest financial strategies to support clinical pharmacy services within a multidisciplinary team. As patients transition from inpatient to outpatient settings and between multiple caregivers, pharmacists can positively affect medication reconciliation and education, assure consistency in management that results in improvements in patient satisfaction and medication adherence, and reduce medication errors. For mechanical circulatory support and heart transplant teams, the Centers for Medicare and Medicaid Services considers the participation of a transplant pharmacology expert (e.g., clinical pharmacist) to be a requirement for accreditation, given the highly specialized and complex drug regimens used. Although reports of outcomes from pharmacist interventions have been mixed owing to differences in study design, benefits such as increased use of evidence-based therapies, decreases in HF hospitalizations and emergency department visits, and decreases in all-cause readmissions have been demonstrated. Clinical pharmacists participating in HF or heart transplant teams should have completed specialized postdoctoral training in the form of residencies and/or fellowships in cardiovascular and/or transplant pharmacotherapy, and board certification is recommended. Financial mechanisms to support pharmacist participation in the HF teams are variable. CONCLUSIONS: Positive outcomes associated with clinical pharmacist activities support the value of making this resource available to HF teams.

Discharge counseling for patients with heart failure or myocardial infarction: a best practices model developed by members of the American College of Clinical Pharmacy's Cardiology Practice and Research Network based on the Hospital to Home (H2H) Initiative.

Hospital to Home is a quality-based initiative led by the American College of Cardiology and the Institute for Healthcare Improvement, aimed at reducing 30-day hospital readmission rates for patients with heart failure or myocardial infarction. Several factors have been shown to attribute to early readmission for these conditions including comorbidities, environmental factors, insufficient discharge planning, lack of health literacy, and nonadherence to drug therapy. Pharmacists play a significant role in reducing readmissions by ensuring that appropriate evidence-based pharmacotherapy regimens have been prescribed during hospitalization; monitoring for drug duplications, medication errors, and adverse reactions; and performing medication reconciliation. Studies have demonstrated the role of pharmacists in reducing medication-related visits to the emergency department as well as hospital readmissions, solely by preventing adverse drug events. Although all of these factors impact early readmissions, providing quality counseling to the patient as well as the patients' caregiver(s) at discharge is critical in order to optimize adherence as well as outcomes. In order to accomplish the goal of reducing readmissions, health care providers must partner together across the continuum of care and include pharmacists as pivotal members of the health care team. In this best practice statement, we summarize key components of discharge counseling for patients with heart failure or myocardial infarction including medication use, medication dose and frequency, drug interactions, medications to avoid, common adverse effects, role of the medication in the disease state, signs and symptoms of the disease, diet, the patient's role in self-care (lifestyle modifications), and when patients should seek medical advice.

Statins and daptomycin: safety assessment of concurrent use and evaluation of drug interaction liability.

BACKGROUND: Acute muscle injury and potentially fatal rhabdomyolysis may occur with use of statins and certain interacting medications. This investigation assessed risk for myopathy in patients receiving treatment with a statin in combination with daptomycin, a medication also associated with muscle injury. METHODS: Patients hospitalized from July 1, 2005, through June 30, 2010, who received simvastatin or rosuvastatin concurrently with daptomycin were identified and their medical records were examined. Patients were judged to have treatment-related muscle injury if their records contained evidence of myalgia with or without weakness and secondarily impaired mobility together with elevated creatine kinase (CK) levels. These assessments were compared with similar data from hospitalized patients who received a statin alone. RESULTS: A total of 52 patients received 66 courses of concurrent treatment with simvastatin or rosuvastatin and daptomycin. Of these, no patient (0%) met evidentiary requirements for diagnosis of myopathy or related complications. No patient (0%) developed muscle pain or discomfort and none developed markedly elevated CK levels. The incidence of asymptomatic elevations of CK in these simvastatin or rosuvastatin plus daptomycin recipients (9%) was statistically indistinguishable from the incidence of CK elevations found in a cohort of 105 inpatients who received simvastatin or rosuvastatin alone (21%; p=0.135). CONCLUSIONS: In patients receiving treatment with simvastatin or rosuvastatin and daptomycin, no symptoms or objective evidence of muscle injury attributable to a drug interaction were identified. These findings are consistent with data indicating that the myopathic effects of statins and daptomycin are incited by disparate and perhaps unique pharmacological mechanisms. Risk of muscle injury therefore appears to be no greater when a statin is administered with daptomycin than when either medication is used alone.

Cost-effectiveness of statin therapy for vascular event prevention in adults with elevated C-reactive protein: implications of JUPITER.

OBJECTIVES: High-sensitivity C-reactive protein (hs-CRP) has been explored for use in predicting cardiovascular risk. The recent Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER) study found that statin therapy reduced cardiovascular events in those with low-density lipoprotein (LDL) cholesterol levels below current treatment thresholds (≤130 mg/dL, 3.4 = mmol/L), but with elevated hs-CRP levels (≥2.0 mg/L). This study examines the cost-effectiveness of statin treatment for individuals with elevated hs-CRP but normal LDL cholesterol. METHODS: A Markov decision-analytic model was conducted from the U.S. societal perspective. Data from JUPITER were used to estimate rates of myocardial infarction, angina and stroke. Statin costs were based on generic simvastatin 80 mg, equipotent to the rosuvastatin 20 mg dose used in JUPITER. Primary prevention was the focus and secondary prevention was not modeled explicitly. Quality-adjusted life-years (QALYs) were calculated using nationally representative preference-based utility weights. One-way sensitivity analyses and multivariate probabilistic sensitivity analysis were used to explore uncertainty in model parameters as well as estimate the likelihood of cost-effectiveness when all event rates, costs and utilities were drawn randomly from distributions reflecting uncertainty. RESULTS: Statin therapy cost $10,889/QALY for vascular event prevention in this population. Results were sensitive to the cost of statin treatment. Based on 10,000 simulations, statin therapy was cost-effective in 99.5% of simulations, using a willingness-to-pay threshold of $20,000/QALY, and 100% of simulations using a threshold of $50,000/QALY. CONCLUSIONS: Treatment with statins in patients with elevated hs-CRP but normal cholesterol appears to be cost-effective. Limitations of this study include the assumption that an equipotent dose of simvastatin resulted in the same risk reduction as rosuvastatin. Further, post-event states simulated the average experience of a patient. Continued statin use, subsequent events and/or heart failure were not explicitly modeled.

The risk of adverse drug events and hospital-related morbidity and mortality among older adults with potentially inappropriate medication use.

BACKGROUND: Inappropriate medication prescribing is a significant problem among older adults that may contribute to increased morbidity and mortality as well as increased costs of care. The development of specific lists of medications that are considered potentially inappropriate for older adults, such as the Beers criteria (BC), make it relatively easy to study prescribing practices in large numbers of patients. OBJECTIVE: The goal of this study was to determine how frequently adverse drug events (ADEs) in the acute care setting are related to BC medications and to determine if BC medication prescribing is significantly associated with the occurrence of ADEs and other negative outcomes in older hospitalized adults. METHODS: This was a retrospective review of patients aged > or =75 years admitted to 2 adult internal medicine services over 18 months (March 2000-August 2001). Data regarding general demographic and clinical information were collected; this information included place of residence before admission and at discharge; medications at admission, during the hospital stay, and at discharge; ADEs; length of stay; and in-hospital mortality Patient medical records were used to determine the occurrence of ADEs. RESULTS: : A total of 389 patients (68.9% female; mean age, approximately 79 years) were included. Of these 389 eligible patients, 107 (27.5%) were prescribed a total of 116 BC medications, and 124 (31.9%) experienced a total of 131 ADEs. Only 9.2% (12/131) of the ADEs were attributed to medications listed among the BC. After controlling for covariates, prescription of a BC medication was not significantly associated with experiencing an ADE (adjusted odds ratio [OR], 1.51; 95% CI, 0.98-2.35; P = 0.064), length of stay (adjusted OR, 1.03; 95% CI, 0.64-1.63; P = 0.91), discharge to higher levels of care (adjusted OR, 1.39; 95% CI, 0.82-2.34; P = 0.22), or in-hospital mortality (adjusted OR, 1.49; 95% CI, 0.77-2.92; P = 0.24). CONCLUSIONS: Interventions targeted specifically at BC medications would have seemingly done little to change the risk of ADEs in this population. Interventions that are more comprehensive than the BC are necessary to reduce the risk of ADEs and the associated morbidity and mortality in acute care of the elderly.
