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.

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.

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.

Impact of hematopoietic growth factors on blood transfusion needs, incidence of neutropenia, and overall survival among elderly advanced ovarian cancer patients treated with chemotherapy.
The researchers sought to determine the effectiveness of erythropoietin-stimulating agent (ESA) and granulocyte colony-stimulating factor (CSF) in reducing blood transfusion needs and neutropenia incidence in community-dwelling elderly ovarian cancer patients. They found that erythropoietin-stimulating agents were effective in reducing blood transfusion need. Granulocyte colony-stimulating factors were effective in lowering neutropenia incidence and also were associated with improved survival in elderly ovarian cancer patients.

The comparative effectiveness of biologics among older adults and disabled rheumatoid arthritis patients in the Medicare population.
Older and disabled rheumatoid arthritis (RA) patients are often not present in large numbers in clinical trials or registries. Using a novel, claims-based clinical effectiveness algorithm with the potential to compare the effectiveness of different biologics among this population using large administrative databases, researchers found that abatacept, adalimumab and etanercept are more effective than infliximab among RA patients initiating biologics.

Clinical outcomes of early and later physical therapist services for older adults with back pain.
The purpose of this study was to compare clinical outcomes of patients receiving early or later PT services with those not receiving PT among older adults presenting to primary care for a new visit for back pain. It found that among older adults early referral to PT resulted in no or minimal differences in pain, function, or health-related quality at 3, 6, or 12 months compared with a matched group that did not receive early PT.

Patient-reported outcomes associated with use of physical therapist services by older adults with a new visit for back pain.
The researchers conducted an observational comparative effectiveness research study to investigate the association between types or amounts of physical therapist services and outcomes, such as disability and pain intensity, among older adults. Higher amounts of active physical therapy were associated with decreased back and leg pain and increased odds of clinically meaningful improvements in back and leg pain relative to results obtained with no active physical therapy.

Cost-utility analysis of chemotherapy regimens in elderly patients with stage III colon cancer.
The authors investigated community-level evidence on the effectiveness and cost effectiveness of treatment for stage III colon cancer for elderly patients among those receiving no chemotherapy, 5-fluorouracil (5-FU), and FOLFOX (5-FU + oxaliplatin). They concluded that FOLFOX appears more effective and cost effective than other strategies for colon cancer treatment of older patients, with results being sensitive to age.

Impact of liver-directed therapy in colorectal cancer liver metastases.
This study evaluated the use of liver resection, ablation, and chemoembolization (LDT) in older patients presenting with metastatic colorectal cancer in the setting of improved chemotherapy. It found that many older patients deemed to be appropriate candidates for resection of the primary tumor and receipt of systemic chemotherapy did not receive LDT.

Effectiveness of mesh compared with nonmesh sling surgery in Medicare beneficiaries.
This study assessed the effectiveness of mesh compared to nonmesh slings in the surgical treatment of female incontinence. It found that overall rates of complications were similar for patients undergoing either mesh or nonmesh sling procedures. However, patients undergoing the nonmesh procedure were more likely to require a subsequent intervention for bladder outlet obstruction.
