Insurance expansion and the utilization of inpatient surgery: evidence for a "Woodwork" effect?
The researchers examined rates of elective surgery in previously insured individuals before and after Massachusetts health care reform. They observed no increase in the overall rate of selected discretionary inpatient surgeries in Massachusetts versus control states for the entire population , as well as among the white and low-income subgroups.

The risk paradox: use of elective cholecystectomy in older patients is independent of their risk of developing complications.
For older patients with newly diagnosed symptomatic gallstones, researchers calculated their 2-year risk of emergent gallstone-related hospitalization. They found that patients in the high-risk group were less likely to receive elective cholecystectomy than those in the low-risk group. The study used Texas Medicare data for 161,568 patients with an episode of symptomatic gallstones.

Thirty-day postoperative mortality among individuals with HIV infection receiving antiretroviral therapy and procedure-matched, uninfected comparators.
The researchers explored the current relationship between perioperative mortality and indicators of immune function, anemia, and hypoalbuminemia among HIV-infected and uninfected individuals. Among HIV-infected patients receiving antiretroviral therapy, modern postoperative mortality rates are low and lower CD4 cell counts are associated with increased mortality, but characteristics other than HIV status, such as age and hypoalbuminemia, are also important determinants of outcome.

Postoperative burden of hospital-acquired Clostridium difficile infection.
This study of 35,363 surgical patients found that 0.51 percent developed a clostridium difficile infection (CDI), with the highest rates occurring after lower-extremity amputation, bowel resection or repair, and gastric or esophageal operations. Post-operative CDI was also associated with higher rates of extended length of stay, emergency room presentations, and readmissions.
