Implementing Publicly Funded Noninvasive Prenatal Testing for Fetal Aneuploidy in Ontario, Canada: Clinician Experiences With a Disruptive Technology.

The last decade has experienced unprecedented uptake of noninvasive prenatal testing (NIPT), creating significant changes in the way prenatal clinicians provide services. Through the lens of social shaping of technology, we examine the effects of the introduction of this technology on the health care system in Ontario, Canada. Using a qualitative descriptive approach, we conducted a cross-sectional study investigating clinicians' perspectives of NIPT in 2014, 2016, and 2018. Through in-depth interviews (n = 37), we explored their perspectives on the impact of NIPT on their referral practices, workload, coordination of testing modalities, education and counseling, and elicited their views on recent expansions of the test. Findings suggest that the introduction of NIPT has created unintended consequences with respect to clinician workload and wellness, clinician education, equity of access, and public system resources. Responsiveness from decision makers is key to ensuring the responsible use of NIPT in the health care system.
