Characterizing Baclofen Withdrawal: A National Survey of Physician Experience.

OBJECTIVE

We studied physicians' opinions and experiences concerning clinical concerns, perceived severity, occurrence, and management of baclofen withdrawal due to abrupt discontinuation.

METHODS

A nationwide 26-question electronic survey was distributed via e-mail to physicians (N = 952) representing varying specialties who manage spasticity with baclofen. A total of 110 physicians provided responses to the survey (response rate = 11.6%). Results were evaluated using descriptive statistics.

RESULTS

Withdrawal from both oral and intrathecal (IT) baclofen was recognized as a significant concern and was observed by most respondents. However, approximately 75% and 35% of respondents or their clinic sites lack established management protocols for managing anticipated interruption of oral or IT baclofen, respectively.

CONCLUSIONS

These findings highlight the need for further research on and the development of guidelines for the prevention and treatment of baclofen withdrawal. The results of this survey, along with a systematic literature review and multidisciplinary stakeholder input, may be helpful in establishing guidelines for the treatment and prevention of baclofen withdrawal.
