Laboratory Monitoring Practices Among Canadian Multiple Sclerosis Clinicians

Abstract

ABSTRACT:Background: Advances in multiple sclerosis (MS) disease modifying therapy (DMT) have increased laboratory monitoring requirements. Our goal was to survey existing practices and perceptions of risk in laboratory monitoring throughout Canada and assess whether opportunities to improve patient care and safety exist. Methods: A web-based survey assessing prescriber demographics, current infrastructure, and concerns for lab monitoring was sent to the Canadian Network of MS Clinics (CNMSC) listserv, inviting MS clinicians across the country to participate. Results: Respondents included 32/65 CNMSC-affiliated neurologists (49%), 6 registered nurses (RN), 2 nurse practitioners (NP), and 2 non-neurologist physicians from 8/10 provinces. For some questions, analysis was limited to 34 DMT-prescribing clinicians only. Despite broad implementation of electronic medical records (25/34, 74%), many prescribers (15/34, 44%) still receive laboratory results in paper form. In terms of lab monitoring infrastructure, we noted regional variability in the employment of nursing to monitor patient compliance with required laboratory monitoring. There is also a gap in laboratory surveillance, as less than 5% of respondents reported regularly reviewing results on weekends. Providers’ length of practice and volume of MS patients were not associated with different perception of DMT laboratory monitoring risk. Conclusions: This nation-wide survey showed variability in infrastructure used in laboratory monitoring and regional variation in nursing involvement. Providers’ level of concern for laboratory monitoring for DMTs did not vary by years of experience or volume of MS patients followed, suggesting that improved systems, rather than education, could ameliorate perceptions of risk.
