Design: Retrospective observational cohort, 2008–2013. The study population consisted of unique patients with a single thyroid procedure performed by a low- or high-volume surgeon in 2008 to 2013.
Setting: Kaiser Permanente Northern California and Southern California.
Synopsis: Outcomes studied were 30-day rates of complications, postdischarge utilization, mortality, surgical cut-to-close time, length of stay, and the proportion of outpatient cases. Complications were measured dichotomously as present or not during the first 30 days after surgery and included surgery-related complications: hematoma, stridor, transient hypocalcemia, and vocal cord paralysis/paresis.
