A survey of minimally invasive surfactant therapy in Canada.

Abstract

IntroductionMinimally invasive surfactant therapy (MIST) can be used to treat neonatal respiratory distress syndrome in neonatal intensive care units (NICUs). Clinical and institutional variances in MIST utilization persist globally with little published research regarding MIST utilization in Canada. Therefore, the objective of this study was to survey MIST utilization in NICUs in Canada.MethodsAn online survey was emailed to the 33 participating centres of Canadian Neonatal NetworkTM (CNN) Evidence-based Practice for Improving Quality (EPIQ) Lung Health Group (LHG). Site demographics and surfactant therapy procedural details were categorically collected. Free text and multiple-choice questions were utilized to capture perceived barriers and individual preferences for MIST use.ResultsTwenty-eight of 33 participating members of the CNN EPIQ-LHG completed the survey between April 2021 and October 2021 (85%); 17/28 (61%) respondents reported ongoing MIST utilization at their center. Most centers that used MIST techniques administered bovine lipid extract surfactant (68%), commonly using angiocatheters (47%) and purpose-built catheters (41%). MIST was widely used for patients at 26–33 weeks gestational age (88%). Nine centres had never used MIST (32%), and 3 indicated a plan to implement MIST within the next 2 years. Common barriers to MIST use included lack of consensus amongst clinicians (78%), lack of training (56%), and lack of experience with MIST (56%).ConclusionWhile MIST is being increasingly used in Canadian NICUs, universal use is yet to be seen. Clinician inexperience and lack of consensus, formal training, and local guidelines contribute to underutilization of MIST. Training workshops, country-wide data collection, and uniform operating protocols are needed to standardize practice.
