Comparative effectiveness of angiotensin II receptor blockers and angiotensin-converting enzyme inhibitors in older nursing home residents after myocardial infarction: a retrospective cohort study.
Evidence regarding differences in outcomes between angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) among older nursing home (NH) residents after acute myocardial infarction (AMI) is limited. The purpose of this study was to estimate the post-AMI effects of ARBs versus ACEIs on mortality, rehospitalization, and functional decline outcomes in this important population.

Benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia
This is a systematic review and meta-analysis of the benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia (CATD). Studies with low or medium risk of bias (ROB) were analyzed and rated. The analysis concluded there was a slight reduction in short-term cognitive decline with cholinesterase inhibitors and memantime, and cholinesterase inhibitors slightly reduced reported functional decline. There was mostly insufficient evidence on drug treatment of behavioral and psychological symptoms of dementia and on supplements for all outcomes.

Effects of statins for secondary prevention on functioning and other outcomes among nursing home residents.
Studies examining the effects of statins after acute myocardial infarction (AMI) excluded frail older adults, especially nursing home (NH) residents, and few examined functional outcomes. Older NH residents may benefit less from statins and be particularly susceptible to adverse drug events like myopathy-related functional decline. In this retrospective cohort study, the investigators evaluated the effects of statins on 1-year functional decline, rehospitalization, and death in NH residents.

Association of preoperative opioid use with mortality and short-term safety outcomes after total knee replacement.
The purpose of this study was to determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement (TKR). Findings show that continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. Highlights include the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

Association between secondary prevention medication use and outcomes in frail older adults after acute myocardial infarction.
In order to examine the effect of using more guideline-recommended medications after myocardial infarction on mortality, rehospitalization, and functional decline in the frailest and oldest segment of long-stay nursing home residents, researchers conducted a retrospective cohort study of U.S. nursing home residents aged 65 years or older. Exposure was the number of secondary prevention medications initiated after myocardial infarction; outcomes were 90-day death, rehospitalization, or functional decline. The results of the study indicate that the use of more guideline-recommended medications after myocardial infarction was associated with decreased mortality in older, predominantly frail adults, but there was no difference in rehospitalization. Functional decline outcomes were discordant and the researchers note that this does not rule out an increased risk associated with more medication use.

Effect of bisphosphonates on fracture outcomes among frail older adults.
The purpose of this study was to estimate the effects of bisphosphonates on hip fractures, nonvertebral fractures, and severe esophagitis among frail, older adults. Participants were residents of long-stay U.S. nursing homes who were 65 years and older and had no recent use of osteoporosis medication. The matched cohort included new bisphosphonate users and an equal number of calcitonin users. Outcomes for hip fracture, nonvertebral fracture, and esophagitis were measured using Part A claims. Bisphosphonate users were less likely than calcitonin users to experience hip fracture, but had similar rates of nonvertebral fracture and esophagitis events. The researchers conclude that bisphosphonate use is associated with a meaningful reduction in hip fracture among frail, older adults.

Outcomes of "diabetes-friendly" vs "diabetes-unfriendly" beta-blockers in older nursing home residents with diabetes after acute myocardial infarction.
This study analyzed outcomes of using beta-blockers that are considered “diabetes-friendly” vs “diabetes-unfriendly” in older nursing home residents with diabetes after acute myocardial infarction (AMI). Primary outcomes included hospitalizations for hypoglycemia and hyperglycemia in the 90 days after AMI and secondary outcomes functional decline, death, all-cause re-hospitalization and fracture hospitalization. Out of 2855 nursing home residents with type-2 diabetes (T2D), 29% were prescribed a diabetes-friendly beta-blocker vs. 24% without. T2D medicine showed a reduction in hospitalization for hyperglycemia but was unassociated with hypoglycemia. For secondary outcomes T2D-friendly beta-blocks were associated with a greater rate of re-hospitalization but not death, functional decline, or fracture.

Pain treatments after hip fracture among older nursing home residents.
In this retrospective cohort study the investigators examined the association between use of opioids versus other analgesics with death and functioning after hip fracture in older nursing home (NH) residents. The investigators concluded that a rigorous study addressing the limitations of their study is critical to validate their preliminary findings and provide evidence about the effect of using opioid versus nonopioid analgesics to optimize acute pain in NH residents with a hip fracture.

Sex-specific comparative effectiveness of oral anticoagulants in elderly patients with newly diagnosed atrial fibrillation.
This study assessed the sex-specific, comparative effectiveness of direct oral anticoagulants (rivaroxaban and dabigatran), compared to each other and to warfarin among patients with atrial fibrillation. It concluded that the reduced risk of ischemic stroke in patients taking rivaroxaban, compared with dabigatran and warfarin, seems to be limited to men, whereas the higher risk of bleeding seems to be limited to women.

Improving medication adherence and health outcomes in older adults: an evidence-based review of randomized controlled trials.
The objective of this review was to provide an updated summary of evidence from randomized controlled studies to determine whether interventions aimed at improving medication adherence also improve the health outcomes of older adults residing in community-based settings. This evidence-based review of medication adherence interventions in older adults revealed promising strategies in the larger context of a largely mixed body of literature.

Comparative effectiveness of radiotherapy with vs. without temozolomide in older patients with glioblastoma.
It is unknown whether the addition of temozolomide (TMZ) to radiotherapy (RT) is associated with improved overall survival among older glioblastoma patients. This study found that among a large cohort of older glioblastoma patients treated in a real-world setting, the addition of TMZ to RT was associated with a small survival gain.

Patient priority weighting of the Roland Morris Disability Questionnaire does not change results of the lumbar epidural steroid injections for spinal stenosis trial.
The researchers reevaluated whether outcomes for older adults receiving epidural steroid injections with or without corticosteroid improve after using patient-prioritized Roland-Morris Disability Questionnaire (RDQ) items. Their findings provide additional evidence that epidural injection of corticosteroid + lidocaine offered minimal or no short-term benefit as compared with epidural injection of lidocaine alone for older adults with lumbar spinal stenosis.

Effectiveness and safety of aldosterone antagonist therapy use among older patients with reduced ejection fraction after acute myocardial infarction.
The purpose of this paper is to describe how aldosterone antagonist treatment is used among older myocardial infarction (MI) patients in routine practice. They found that aldosterone antagonist use was not associated with lower mortality except in symptomatic HF patients, and risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists, as was risk of acute renal failure compared with patients not prescribed aldosterone antagonists. They concluded that these results underscore the importance of close post-discharge monitoring of this patient population.
