Reducing Surgical Site Infections in a Children’s Hospital: The Fuzzy Elements of Change

Discussion

Duration of Project

The total duration of the Sickkids effort to measure and reduce the rate of SSI and thereby improve the quality of surgical care took almost 8 years. The duration, which ideally should have been about one quarter of that time, was due to multiple issues. First, there were many simultaneous competing demands to improve quality in other IOM domains such as safety and efficiency. Second, no one on the task force had protected time and thus meetings could be no more than monthly because people could not complete tasks in a shorter time frame. Third, many of the steps relied on wider physician involvement such as reviewing the revised guidelines. The physicians were slow to respond and only after all 9 surgical disciplines had signed off on the guidelines could implementation proceed. Finally, many of the important issues came up only after implementation of a specific step. For example, the recognition of the need for an individual audit and feedback mechanism created the need of mapping the procedures to guidelines to SIS procedures, a process that took more than a year to complete. Also the responses to the emails created the need for revisions to the guideline with subsequent delays for re-approval with hospital and IT support for eformulary changes.

Success Factors and Impediments

The factors that in retrospect seem critical to effecting positive change started with a general endorsement of the perioperative services group for improving quality and specifically SSI. The retreat and an open forum involving multiple disciplines was critical in creating a mandate for change. Second, the task force not only had multiple and key discipline representation for each aspect of the change management strategy, but the task force members were passionate about the importance of reducing SSI. Third, the multiple strategies used for change needed to be adaptive and iterative to new findings as they arose. While the task force attempted to anticipate barriers to change, only once the quality initiative started did the task force truly understand the barriers and respond in turn. Finally, the need for relentless energy by the leaders and task force was critical to seeing the project to completion.

While the appropriate use of antibiotics increased with a reduction in SSI, several aspects of this initiative were not successful. First, despite the surgeon-in-chief’s semi-annual lectures, this initiative did not successfully engage the majority of the house staff manifested by their continued habit of prescribing postoperative antibiotics for hours to days despite the guideline advice. Second, because nurses were tasked with asking about and recording the use of antibiotics, an unintended consequence was that they took the brunt of disgruntled physicians. Despite all our attempts, many nurses felt this initiative brought negative responses of physicians toward their charting duties. Third, while audit and feedback was an important strategy to improve guideline compliance, many physicians saw the daily emails in response to noncompliance with the guidelines as intrusive and irritating. Also we could not program SIS to make it a decision support in real time rather than documenting an event after the fact and, thereby, not enhancing care for that individual patient. Finally, we adopted a strategy of health record coding for SSI due to the prohibitive expenses of a comprehensive active monitoring strategies by ICPs.

Exportability

The strategies used in this quality improvement project to reduce SSI may be exportable to other hospitals with similar results. However, the emphasis on which element of change management strategy is most important would likely vary by context [2,6]. The elements most essential for success were a mechanism to develop group buy-in, a dedicated multidisciplinary task force with leader(s) with relentless commitment to achieving meaningful change, and a mechanism to evaluate both the process measures and the final outcome. The elements of change would vary by site and including consideration of the mechanism for physician compensation, commitment of physicians to institutional initiatives to enhance quality, and institutional resources to support quality initiatives.

None of the observed changes in this quality improvement initiative can be confidently attributed to any of the specific interventions. The interventions were completed in stages, but most importantly were constantly changed, emphasized and de-emphasized according to the responses. This is the fuzzy nature of change whereby leaders take reasonable steps to effect change but have to constantly adapt to barriers to change. While a specific change strategy generalizable to all contexts would be ideal, in the end at an institutional level, positive change is the ultimate aim rather than determining which interventions are effective. This response to events as they arise as illustrated in our quality improvement journey, is the fuzzy side of change management.

Conclusion

In conclusion, through a long period with a multitude of strategies, use of a guideline for prophylactic antibiotics increased and was associated with a reduction in SSI. Future directions need to consider cost-effective strategies to actively monitor SSI and testing of other strategies to reduce SSI. Institutions embarking on change need to consider that initiatives will likely need to adapt to specific contextual responses.
