    IMPORTANCE: Guidelines recommend delaying noncardiac surgery in patients after coronary stent procedures for 1 year after drug-eluting stents (DES) and for 6 weeks after bare metal stents (BMS). The evidence underlying these recommendations is limited and conflicting.

    OBJECTIVE: To determine risk factors for adverse cardiac events in patients undergoing noncardiac surgery following coronary stent implantation.

    DESIGN, SETTING, AND PARTICIPANTS: A national, retrospective cohort study of ...

    OBJECTIVES: The goal of this study was to compare long-term survival and valve-related complications between bioprosthetic and mechanical heart valves.

    BACKGROUND: Different heart valves may have different patient outcomes.

    METHODS: Five hundred seventy-five patients undergoing single aortic valve replacement (AVR) or mitral valve replacement (MVR) at 13 VA medical centers were randomized to receive a bioprosthetic or mechanical valve.

    RESULTS: By survival analysis at 15 years, all-cause ...

    OBJECTIVE: To determine whether the investment in postgraduate education and training places patients at risk for worse outcomes and higher costs than if medical and surgical care was delivered in nonteaching settings.

    SUMMARY BACKGROUND DATA: The Veterans Health Administration (VA) plays a major role in the training of medical students, residents, and fellows.

    METHODS: The database of the VA National Surgical Quality Improvement Program was analyzed for all major noncardiac operations ...

    OBJECTIVE: The purpose of the study was to investigate the incidence, predictors, morbidity, and mortality associated with postoperative atrial fibrillation (AF) and its impact on intensive care unit (ICU) and postoperative hospital stay in patients undergoing cardiac surgery in the Department of Veterans Affairs (VA).

    SUMMARY BACKGROUND DATA: Postoperative AF after open cardiac surgery is rather common. The etiology of this arrhythmia and factors responsible for its genesis are unclear, ...

    BACKGROUND: Although aspirin therapy started before operation improves vein graft patency after coronary artery bypass grafting, it also causes bleeding. The objective of this prospective, centrally directed, randomized, double-blind, placebo-controlled trial was to compare the effects of aspirin therapy started before operation with aspirin started 6 hours after operation on early (7-10-day) graft patency.

    METHODS AND RESULTS: Patients were randomized to receive either aspirin 325 mg or ...

    OBJECTIVE: The utilization of joint arthroplasty for knee or hip osteoarthritis varies markedly by patient race/ethnicity. Because of concerns about surgical risk, black patients are less willing to consider this treatment. There are few published race/ethnicity-specific data on joint arthroplasty outcomes. The present study was undertaken to examine racial/ethnic differences in mortality and morbidity following elective knee or hip arthroplasty.

    METHODS: Using information from the ...

    BACKGROUND: The long-term success of coronary bypass surgery is dependent on graft patency after surgery. This trial was designed to determine if aspirin improved saphenous vein graft or internal mammary artery (IMA) graft patency between 1 and 3 years after coronary artery bypass grafting (CABG).

    METHODS AND RESULTS: After receiving aspirin 325 mg/d for 1 year after CABG and undergoing a 1-year postoperative cardiac catheterization, patients were randomized to receive either aspirin ...

    OBJECTIVE: Blood loss during surgery is an important operative complication in patients undergoing major noncardiac surgery and may increase postoperative morbidity and mortality. Variations in the delivery of operative blood transfusions to treat blood loss depend not only on the patient and surgery characteristics but also on the hospital transfusion practices, and may explain differences in the hospitals' postoperative outcomes. We determine the relationship between hospital-level ...

    IMPORTANCE: Timing of prophylactic antibiotic administration for surgical procedures is a nationally mandated and publicly reported quality metric sponsored by the Centers for Medicare and Medicaid Services Surgical Care Improvement Project. Numerous studies have failed to demonstrate that adherence to the Surgical Care Improvement Project prophylactic antibiotic timely administration measure is associated with decreased surgical site infection (SSI). OBJECTIVE; To determine whether ...

    ABSTRACTBACKGROUNDPatients who misuse alcohol are at increased risk for surgical complications. Four weeks of preoperative abstinence decreases the risk of complications, but practical approaches for early preoperative identification of alcohol misuse are needed.OBJECTIVETo evaluate whether results of alcohol screening with the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) questionnaire—up to a year before surgery—were associated with the risk of postoperative ...

    BACKGROUND: Clozapine, a relatively expensive antipsychotic drug, is widely used to treat patients with refractory schizophrenia. It has a low incidence of extrapyramidal side effects but may cause agranulocytosis. There have been no long-term assessments of its effect on symptoms, social functioning, and the use and cost of health care.

    METHODS: We conducted a randomized, one-year, double-blind comparative study of clozapine (in 205 patients) and haloperidol (in 218 patients) at 15 ...

    OBJECTIVES: This study was designed to compare the three-year survival after percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG) in physician-directed and patient-choice registries with the Angina With Extremely Serious Operative Mortality Evaluation (AWESOME) randomized trial results.

    BACKGROUND: The AWESOME multicenter randomized trial and registry compared the long-term survival after PCI and CABG for the treatment of patients with medically ...
