Implementation of patient-reported outcome measures in U.S. total joint replacement registries: rationale, status, and plans.
The authors report on the status of patient-reported outcomes (PRO) implementation as well as perceived barriers and facilitators of PRO use among five U.S. total joint replacement registries. They find that the current stage of implementation of patient-reported outcomes measures varies widely among U.S. registries.

Cost-effectiveness of elective laparoscopic cholecystectomy versus observation in older patients presenting with mild biliary disease.
The objective was to determine the threshold for probability of recurrent symptoms at which elective cholecystectomy became the most effective and cost-effective options for older patients with mild biliary disease. This procedure was more effective than observation when the probability of continued symptoms exceeded 45.3 percent; when the probability exceeded 82.7 percent, the procedure became more cost-effective as well.

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.

Indications for spine surgery: validation of an administrative coding algorithm to classify degenerative diagnoses.
The Spine Patient Outcomes Research Trial (SPORT) provided a unique opportunity to examine the validity of a claims-based algorithm for grouping patients by surgical indication. SPORT enrolled patients for lumbar disc herniation, spinal stenosis, and degenerative spondylolisthesis. The researchers found that their claims-based hierarchical coding algorithm of spine-related medical encounters correctly classified more than 90 percent of Medicare patients into their respective SPORT cohorts.

Comparative effectiveness of endovascular and surgical revascularization for patients with peripheral artery disease and critical limb ischemia: systematic review of revascularization in critical limb ischemia.
This systematic review found that there is no difference in clinical outcomes for patients with critical limb ischemia treated with endovascular or surgical revascularization. This review of 23 studies found no differences in overall death, amputation, or amputation-free survival at 2 or more years following treatment.
