ReviewDoes close temperature regulation affect surgical site infection rates?
The argument for close temperature control, to which regulatory bodies have held health systems in an effort to reduce the burden of hospital-acquired infections, is not fully supported by current evidence. The literature is complex on the topic, and overinterpretation of historical data supporting close temperature regulation does not preclude an important recognition of these early works' contribution to high-quality surgical care. Avoidance of hypothermia through the regular use of active rewarming should be a routine part of safe surgical care. ⋯ Clinicians, researchers, and policymakers must be careful in how they apply these well-supported findings to process metrics in an era of limited resources with increasingly stringent quality guidelines and outcomes measures. Discrete temperature targets in current measures are not supported by the existing literature. Not only do these targets artificially anchor clinicians to temperature values with an inadequate scientific basis but they demand intensive resources from health institutions that could potentially be better used on quality requirements with stronger evidence of their ultimate effect on patient care.

Laparoscopic cholecystectomy is widely established as the standard operation in acute cholecystectomy. Valid data from several prospective studies, including a recent large randomized multicenter trial, are available, demonstrating that early cholecystectomy is associated with less morbidity, a shorter length of hospital stay, and lower total hospital costs compared with delayed cholecystectomy after a conservative treatment period with antibiotics. Early cholecystectomy within 24 hours of hospital admission is the therapy of choice in patients fit for surgery and should be implemented as the standard treatment algorithm for this condition.

Current recommendations from the 2002 ASA Task Force on Preanesthesia Evaluation are not specific to ambulatory surgery and are not based on strongly designed and adequately powered studies. Furthermore, although the ASA does not advocate routine testing or testing without indication, the guidelines for "selective" or "indicated" testing are unclear. As a result, preoperative testing in the United States is overused relative to the current ASA Task Force recommendations. ⋯ Identification of reasons for overuse of testing is the first step toward changing practice. Once clear guidelines are developed, the creation of preoperative clinics that centralize preoperative care, or promoting the use of clinical pathways and/or checklists for determining appropriate tests, may improve the adequate use of preoperative tests. It will be critical for quality improvement measures to include surgeons, anesthesiologists, hospital administrators, and governing bodies such as the ASA and American College of Surgeons to achieve success.

The practice of general surgery has undergone a marked evolution in the past 20 years, which has been inadequately recognized and minimally addressed. The changes that have occurred have been disruptive to residency training, and to date there has been inadequate compensation for these. Evidence is now emerging of significant issues in the overall performance of recent graduates from at least 3 sources: the evaluation of external agents who incorporate these graduates into their practice or group, the opinions of the residents themselves, and the performance of graduates on the oral examination of the American Board of Surgery during the past 8 years. ⋯ Hence, solutions to the problems must be sought in other areas. To address the issues effectively, greater recognition and engagement are needed by the surgical community so that effective solutions can be crafted. These will need to include improvements in the efficiency of teaching, with the assumption of greater individual resident responsibility for their knowledge, the establishment of more defined standards for knowledge and skills acquisition by level of residency training, with flexible self-assessment available online, greater focus of the curriculum on current rather than historical practice, increased use of structured assessments (including those in a simulated environment), and modifications to the overall structure of the traditional 5-year residency.
