“…Each category of adopters has an expected proportion: Innovators (2.5%), Early Adopters (13.5%), Early Majority (34%), Late Majority (34%), and Laggards (16%) (10). This typical technology adoption life cycle has been found to be applicable to other biotechnologies using 2-to 4-year intervals (11). Because our initial results found that 43% of Massachusetts EDs had adopted video laryngoscopy 9 years since its development (putting it in the Early Majority stage), we used the longer 4-year intervals, dividing the video laryngoscopy technology adoption life cycle into the periods 2000-2003 (Innovators), 2004-2007 (Early Adopters), and 2008 (Early Majority).…”
