Surgeon experience and Medicare expenditures for laparoscopic compared to open colectomy.
This population-based study examined whether surgeon experience with laparoscopy influenced payments for laparoscopy versus open surgery colectomies. The study used 182,852 national Medicare beneficiaries undergoing colectomies between 2010 and 2012. Surgeons with the most laparoscopic experience did experience an average payment savings of $5456 per patient in laparoscopic versus open cases. For surgeons in the lowest quartile of experience there was no difference.

Impact of a claims-based frailty indicator on the prediction of long-term mortality after transcatheter aortic valve replacement in Medicare beneficiaries.
In this study, the investigators sought to characterize the prognostic importance of frailty factors as identified in healthcare billing records in comparison to validated measures of frailty for the prediction of long-term mortality after transcatheter aortic valve replacement (TAVR). The authors suggest that risk prediction models that include frailty as identified in claims data can be used to predict long-term mortality risk after TAVR.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Practical guide to surgical data sets: Medicare claims data.
In this article, the authors discuss pros and cons of Medicare data and explore commonly studied categories using this data (health policy evaluation, comparative effectiveness research, and outcome variations). They conclude that it is important to frame questions carefully and to use appropriate methods to ensure scientific rigor.

National trends in open surgical, endovascular, and branched-fenestrated endovascular aortic aneurysm repair in Medicare patients.
Open repair effectively prevents rupture for patients with abdominal aortic aneurysm (AAA) and is commonly studied as a metric reflecting hospital and surgeon expertise in cardiovascular care. However, given recent advances in endovascular aneurysm repair (EVAR), such as branched-fenestrated EVAR, it is unknown how commonly open surgical repair is still used in everyday practice. This study analyzed trends in open AAA repair, EVAR, and branched-fenestrated EVAR for AAA in Medicare beneficiaries from 2003 to 2013.

Early effects of Medicare's Bundled Payment For Care Improvement program for lumbar fusion.
The purpose of this study was to describe the early effects of Bundled Payment for Care Improvement (BPCI) program participation for lumbar fusion on 90-day reimbursement, procedure volume, reoperation, and readmission. The investigators included 89,605 beneficiaries undergoing lumbar fusion, finding that the mean age was 73.4 years, with 59% women, 92% White, and 22% with a Charlson Comorbidity Index of 2 or more. Participant hospitals had greater procedure volume, bed size, and total discharges. Relative to nonparticipants, risk-bearing hospitals had a slightly increased fusion procedure volume from 2012 to 2013, did not reduce 90-day episode of care costs, increased 90-day readmission rate, and increased repeat surgery rates.

Strategies for reducing population surgical costs in Medicare: local referrals to low-cost hospitals.
An analysis was done of hospital cost variations for elective inpatient surgery in a small geographic area. Medicare payment data was used to calculate 30-day surgical episode costs for elderly patients undergoing 1 of 7 elective surgeries during 2010-2012. The highest and lowest cost hospitals were identified in their metropolitan statistical area. It was found that high-cost hospitals had higher complication and readmission rates than their lower-cost peers. Medicare expenditures at the high-cost hospitals were $4424 to $10,417 higher than the lowest-cost hospitals.
