Adoption of an innovation to repair aortic aneurysms at a Canadian hospital: a qualitative case study and evaluation

<p>Abstract</p> <p>Background</p> <p>Priority setting in health care is a challenge because demand for services exceeds available resources. The increasing demand for less invasive surgical procedures by patients, health care institutions and industry, places added pressure on surgeons to acquire the appropriate skills to adopt innovative procedures. Such innovations are often initiated and introduced by surgeons in the hospital setting. Decision-making processes for the adoption of surgical innovations in hospitals have not been well studied and a standard process for their introduction does not exist. The purpose of this study is to describe and evaluate the decision-making process for the adoption of a new technology for repair of abdominal aortic aneurysms (endovascular aneurysm repair [EVAR]) in an academic health sciences centre to better understand how decisions are made for the introduction of surgical innovations at the hospital level.</p> <p>Methods</p> <p>A qualitative case study of the decision to adopt EVAR was conducted using a modified thematic analysis of documents and semi-structured interviews. Accountability for Reasonableness was used as a conceptual framework for fairness in priority setting processes in health care organizations.</p> <p>Results</p> <p>There were two key decisions regarding EVAR: the decision to adopt the new technology in the hospital and the decision to stop hospital funding. The decision to adopt EVAR was based on perceived improved patient outcomes, safety, and the surgeons' desire to innovate. This decision involved very few stakeholders. The decision to stop funding of EVAR involved all key players and was based on criteria apparent to all those involved, including cost, evidence and hospital priorities. Limited internal communications were made prior to adopting the technology. There was no formal means to appeal the decisions made.</p> <p>Conclusion</p> <p>The analysis yielded recommendations for improving future decisions about the adoption of surgical innovations. ese empirical findings will be used with other case studies to help develop guidelines to help decision-makers adopt surgical innovations in Canadian hospitals.</p

A comparative rewarming trial of gastric versus peritoneal lavage in a hypothermic model.

A comparison of gastric lavage versus peritoneal lavage rewarming was studied in a hypothermic rabbit model. The gastric lavage group (n = 5) had a mean rewarming time of 136 +/- 25.1 minutes versus the peritoneal lavage group (n = 6) mean rewarming time of 131.7 +/- 27.9 minutes (p = .795). Good correlation was found between tympanic membrane temperature readings and both rectal temperature readings (r = .69) in the gastric lavage group and esophageal temperature readings (r = .90) in the peritoneal lavage group. Gastric lavage and peritoneal lavage have the same rewarming rates in the present hypothermic model

The new training paradigms and the unfilled match positions of 2004: Will history repeat itself?

ObjectiveThe new millennium has seen an increase in vascular residency vacancies. The American Board of Vascular Surgery recently proposed new training paradigms, but their impact on recruitment remains unknown. We surveyed vascular fellows regarding factors and timing of career decisions to determine an optimal strategy for recruitment.MethodsSurveys were sent electronically to vascular residents for completion. Data were analyzed using SPSS software. Additional data were obtained from the National Resident Matching Program.ResultsOf the 90 fellows that responded, 84% committed to vascular surgery during residency. Of these, 18% decided during postgraduate year 1, 54% by year 2, 84% by year three, and 95% by year 4. Sixteen percent of all trainees decided in medical school. Seventy-three percent of residents performed a minimum of 20 to 50 cases before reaching a decision. Among the group deciding between years 2 to 4 of residency, there was a significant difference in the number of vascular rotations before career commitment (P = .0001). In the 2004 Match, 21% of vascular residency positions were unfilled, up from 12% in 2003, 9% in 2002, and 4% in 2001.ConclusionsLeaders in the field of vascular surgery have proposed focused training through the new paradigms. The incline in unmatched vascular residency positions over the past 4 years highlights the importance of a strategic plan to optimize recruitment. Few current trainees decided early in training about career choice, and volume appears critical to the decision process. Utilizing the current matching system (an 18-month process) and without any proactive change in recruitment, an integrated program after medical school would be reasonable for only 16% of applicants, or the 3+3 option for 54% of residents. For the new paradigms to be successful and to prevent more unfilled positions, increased medical student integration into vascular rotations and early active exposure to endovascular and open procedures during general surgical training will be necessary across the country
