Update in hospital medicine: studies likely to affect inpatient practice in 2011.

Dabigatran (Pradaxa) will likely start to replace warfarin (Coumadin) both to prevent stroke in patients with atrial fibrillation and to prevent recurrent venous thromboembolism. Using a checklist during insertion of central venous catheters can decrease the rate of catheter-related bloodstream infections in the intensive care unit. The overall survival rate of patients who undergo cardiopulmonary resuscitation in the intensive care unit is approximately 16%; the rate is lower in patients who are receiving pressor drugs and higher in those with ventricular tachycardia or ventricular fibrillation. Patients lacking follow-up with a primary care physician within 30 days of discharge are at high risk of readmission and have a trend for longer length of hospital stay. Preoperative stress testing for patients undergoing noncardiac surgery should be done selectively, i.e., in patients at high risk.
