Frailty as a predictor of death or new disability after surgery: a prospective cohort study.
The purpose of this study was to compare the accuracy of the modified Fried Index (mFI) and the Clinical Frailty Scale (CFS) to predict death or patient-reported new disability 90 days after major elective surgery. Results showed that older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery and that although accuracy was similar, the CFS, compared to the mFI, was easier to use and feasibility was higher.

Relative impact of surgeon and hospital volume on operative mortality and complications following pancreatic resection in Medicare patients.
This study's objective was to evaluate the relative effects of surgeon and hospital volume on mortality and complications after pancreatic resection among older patients. The researchers used Texas Medicare data and found that high surgeon volume and high hospital volume were associated with lower risk of mortality, while high surgeon volume was also associated with lower risk of complications.

Impact of hospital characteristics on failure to rescue following major surgery.
This study determined the effect of hospital characteristics on failure to rescue after high-risk surgery in Medicare beneficiaries. It found that although several hospital characteristics are associated with lower failure to rescue rates, these macrosystem factors explain a small proportion of the variability between hospitals. This suggests that microsystem characteristics may play a larger role in improving a hospital's ability to manage postoperative complications.

Relative contributions of complications and failure to rescue on mortality in older patients undergoing pancreatectomy.
This study evaluated the relative contribution of overall postoperative complications and failure to rescue rates on the observed increased mortality in older patients undergoing pancreatic resection at specialized centers. In experienced hands, the rates of complications after pancreatectomy in patients 80 years or older compared to patients younger than 80 years were similar. However, when complications occurred, older patients were more likely to die.
