Reevaluating a Standardized Sedation Weaning Protocol for Pediatric Laryngotracheal Reconstruction for Continuous Quality Improvement

Abstract

Health care organizations are complex and evolving systems. To date, longitudinal evaluation to ensure the sustainability of quality improvement (QI) initiatives has been missing from the otolaryngology literature. We sought to reassess perioperative management of laryngotracheal reconstruction, which requires adequate sedation. Using principles of continuous QI, the objectives of this study were to (1) describe step-by-step methods to sustain QI efforts and (2) revisit a series of process, outcome, and balance measures for sedation weaning management following implementation of a new electronic health record (EHR). A standardized sedation weaning protocol was previously developed and instituted in February 2013. To address healthcare system-wide changes, a 7-step, Institute for Healthcare Improvement methodology was used to reevaluate a series of measures comparing a previous postweaning group (2013-2014; 13 patients) and current post-EHR group (2016; 11 patients). We conducted a focus group review of these 24 patients. The primary outcome measure was length of sedation weaning. Secondary outcome, process, and balance measures included total length of sedation, absence of standardized wean document, absence of specific recommendations on weaning regimen, length of stay, continued weaning at discharge, discharge location, absence of discharge instructions on weaning regimen or iatrogenic withdrawal syndrome (IWS), discharge within 72 hours of stopping weaning, and readmission. The postweaning and post-EHR groups were similar in age (20.5 months [95% CI, 11.92-29.15] vs 26.5 months [95% CI, 17.68-35.40]), as well as male sex (11 of 13 [85%] vs 10 of 11 [91%]), respectively. In the post-EHR group, the standardized sedation wean document was missing from 9 of 11 (82%) medical records. However, the primary outcome measure, length of sedation weaning, remained stable at 9.45 (95% CI, 7.62-11.29) days in the post-EHR group compared with 9.08 (95% CI, 7.00-11.18) days in the postweaning group. In addition, only 5 of 11 (46%) of discharges in the post-EHR group had specific guidance on weaning since the standardized template was no longer in use. As a result, in the post-EHR group, patients were 15.2 (95% CI, 0.46-242.34) times as likely to lack discharge instructions on weaning or IWS. Quality improvement is meant to be a continuous process in which reevaluation of care practices are regularly performed. System-wide redesign can be achieved using a formal methodological approach. Moving forward, notable QI opportunities for our institution included the development of a flexible sedation weaning template, as well as enhancements to discharge instructions to include IWS diagnosis and treatment.
