Collaborative practice: development, implementation, and evaluation of a weaning protocol for patients receiving mechanical ventilation.

Abstract

BACKGROUND: Use of protocols to reduce weaning time for patients receiving mechanical ventilation helps reduce cost and length of stay. However, implementation of this type of protocol is not easy and requires a consistent collaborative effort. OBJECTIVE: To provide a systematic approach to the weaning process by developing, implementing, and evaluating a protocol for weaning patients from mechanical ventilation in a medical respiratory intensive care unit. METHODS: The weaning protocol used was a modification of a protocol developed by Ely et al. Modifications included a more aggressive approach in proceeding to the spontaneous breathing trial, inclusion of the Richmond Agitation-Sedation Scale, and documentation of the production of secretions. RESULTS: Implementation of the protocol significantly reduced the duration of mechanical ventilation as measured by 8-hour shifts and ventilator days. Although length of stay in the intensive care unit was not significantly reduced (P = .29), a continuing downward trend occurred, from a mean of 8.6 days before the protocol was implemented to 7.9 days during the last 6 months of data collection (P = .07). CONCLUSIONS: The need to provide efficient care requires the collaboration of all disciplines involved in providing patients' care. The weaning protocol introduced in this study demonstrates the benefits of using a collaborative team to identify best practices and implement them in a practice setting.
