OBJECTIVE: Determine if a standardized methadone and lorazepam weaning protocol that is based on dose and duration of exposure can reduce the length of opioid and benzodiazepine weaning and shorten hospital stay.
METHODS: Retrospective cohort study performed in a 24-bed medical/surgical PICU. A total of 177 patients on opioid and/or benzodiazepine infusions for >3 days were included; 75 patients pre protocol (June 2012- June 2013) were compared with 102 patients post implementation of a standardized weaning protocol of methadone and lorazepam (March 2014-March 2015). The recommended wean was based on duration of infusions of >3 days up to 5 days (no wean), 5 to 13 days (short wean), and ≥14 days (long wean).
RESULTS: Median number of days on methadone for patients on opioid infusions for 5 to 13 days was reduced from 8.5 to 5.7 days (p = 0.001; n = 45 [pre], n = 68 [post]) and for patients on opioid infusions for ≥14 days, from 29.7 to 11.5 days (p = 0.003; n = 9 [pre], n = 9 [post]) after protocol implementation. The median number of days on lorazepam for patients on benzodiazepine infusions for 5 to 13 days was reduced from 8.1 to 5.2 days (p = 0.020; n = 43 [pre], n = 55 [post]) and for patients on benzodiazepine infusions for ≥14 days, from 27.4 to 9.3 days (p = 0.011; n = 9 [pre], n = 8 [post]). There was no difference in methadone or lorazepam wean length for patients on 3 to 5 days of infusions. There was no difference in adverse events or hospital length of stay.
CONCLUSIONS: A methadone and lorazepam weaning protocol based on patient's exposure to opioids and benzodiazepines (dose and duration) reduces weaning length.
