A team of researchers led by Penn Medicine anesthesiologists have pinpointed the “top five” most common perioperative procedures that are supported by the least amount of clinical evidence, in an effort to direct providers to make more cost-effective treatment decisions. Their findings are published in the current issue of JAMA Internal Medicine.

The team surveyed anesthesiologists, many of them in academic practice, to identify the most common activities that should be questioned in the field, using practice parameters developed by the American Society of Anesthesiology (ASA) and other perioperative guidelines. Criteria for inclusion were common clinical practices that may be tied to poorer quality of care or increased costs, those for which there is little or no benefit to patients and that could easily be ceased in practice. Items were restricted to common preoperative and intraoperative practices, with the exclusion of postoperative and pain services.

The “Choosing Wisely” campaign is an ongoing effort by the American Board of Internal Medicine Foundation to help physicians become better stewards of health care resources. The Physician’s Charter, a similar initiative, was issued in 2002 and outlined the physician’s responsibilities to ensure access to high quality care by practicing evidence-based medicine, cost-effectively, and maintaining trust by minimizing conflicts of interest. This initiative was adopted by the ASA and more than 130 other organizations.

“The elimination of low-value services in low-risk patients represents a substantial savings, but we needed some consensus from our peers as to what the top least-valued services and procedures were,” said the study’s lead author, Onyi C. Onuoha, MD, MPH, assistant professor of Anesthesiology and Critical Care.

The researchers surveyed their peers on 18 items. First, practicing academic anesthesiologists affiliated with the Society of Academic Anesthesiology Associations responded, narrowing the list to 11 items. The list was then disseminated to the Association of University Anesthesiologists and to a subset of ASA members.

Respondents were overwhelmingly male, from academic practice settings, in practice for more than 20 years and working with the leadership of the ASA.

Survey respondents were asked to report their feedback on each clinical item across five domains, including frequency in practice, impact on quality of care, impact on cost of care, evidence supporting the activity, and the ease in implementation of avoidance.
