Multicenter Study Comparative Study
Comparative effectiveness of laparoscopic adjustable gastric banding vs laparoscopic gastric bypass.
Laparoscopic Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (AGB) are 2 of the most commonly performed bariatric procedures worldwide. However, few large, multisite studies have directly compared the benefits and harms of these procedures. ⋯ In this large bariatric cohort from 10 health care systems, we found that RYGB resulted in much greater weight loss than AGB but had a higher risk of short-term complications and long-term subsequent hospitalizations. On the other hand, RYGB patients had a lower risk of long-term subsequent intervention procedures than AGB patients. Bariatric surgery candidates should be well informed of these benefits and risks when they make their decisions about treatment.

Multicenter Study
Lobectomy, sublobar resection, and stereotactic ablative radiotherapy for early-stage non-small cell lung cancers in the elderly.
The incidence of early-stage non-small cell lung cancer (NSCLC) among the elderly is expected to rise dramatically owing to demographic trends and increased computed tomographic screening. However, to our knowledge, no modern trials have compared the most common treatments for NSCLC. ⋯ Lobectomy was associated with better outcomes than sublobar resection in elderly patients with early-stage NSCLC. Propensity score matching suggests that SABR may be a good option among patients with very advanced age and multiple comorbidities.

Randomized Controlled Trial Multicenter Study
Cost-effectiveness of cervical total disc replacement vs fusion for the treatment of 2-level symptomatic degenerative disc disease.
Cervical total disc replacement (CTDR) was developed to treat cervical spondylosis, while preserving motion. While anterior cervical discectomy and fusion (ACDF) has been the standard of care for 2-level disease, a randomized clinical trial (RCT) suggested similar outcomes. Cost-effectiveness of this intervention has never been elucidated. ⋯ The incremental cost-effectiveness ratio of CTDR compared with traditional ACDF is lower than the commonly accepted threshold of $50,000 per QALY. This remains true with varying input parameters in a robust sensitivity analysis, reaffirming the stability of the model and the sustainability of this intervention.

Multicenter Study
The association between hospital care intensity and surgical outcomes in medicare patients.
Hospitals' care intensity varies widely across the United States. Payers and policy makers have become focused on promoting quality, low-cost, efficient health care. ⋯ Failure-to-rescue rates were lower at high-care intensity hospitals. Conversely, care intensity explains a very small proportion of variation in failure-to-rescue rates across hospitals.
