Risk of acute liver failure in patients with drug-induced liver injury: evaluation of Hy's Law and a new prognostic model.
The researchers aimed to develop a highly sensitive model to identify drug-induced liver injury (DILI) patients at increased risk of acute liver failure (ALF). negative predictive value (0.99), but low level of sensitivity (0.68) and positive predictive value (0.02). Their model, comprising data on platelet count and total bilirubin level, identified patients with ALF with a C statistic of 0.87 and enabled calculation of a risk score (Drug-Induced Liver Toxicity ALF Score).

Significant physiological disturbances associated with non-routine event containing and routine anesthesia cases.
The researchers sought to compare anesthesia providers' reporting of non-routine events (NREs) with the incidence of significant physiological disturbances (SPDs) detected via retrospective videotape review. They concluded that SPDs occur more often in NRE-containing cases. The incidence of approximately one NRE-independent SPD per case was similar in NRE-containing and routine case.

Evaluating term coverage of herbal and dietary supplements in electronic health records.
Some supplements can interact with prescription medications, potentially leading to clinically important and potentially preventable adverse reactions. Clinical notes and corresponding medication lists from an integrated healthcare system were extracted and compared with online databases. The authors found that, overall, about 40% of listed medications are supplements, most of which are included in medication lists as nutritional or miscellaneous products. They found gaps between supplement and standard medication terminologies and identified supplements which were not mentioned in the medication lists.

Medicare coverage of anesthesia services during screening colonoscopies for patients at low risk of sedation-related complications.
The authors examined the costs and potential benefit of the Medicare rule change that waived patient cost sharing for anesthesia services during screening colonoscopies. Their results cast doubt on the value associated with Medicare coverage of anesthesia services during screening colonoscopies for patients at low risk of sedation-related complications. They recommended that payers create payment bundles for endoscopy procedures that include anesthesia services in a fixed fee.

Statins and new-onset diabetes mellitus and diabetic complications: a retrospective cohort study of US healthy adults.
The authors studied the long-term relationship between statin use and new-onset diabetes among Tricare beneficiaries. They found that diabetes, diabetic complications, and overweight/obesity were more commonly diagnosed among statin-users than similar nonusers in a healthy cohort of adults, demonstrating that short-term clinical trials might not fully describe the risk/benefit of long-term statin use for primary prevention.
