Background:
Infection preventionists (IPs) are essential in reducing health care-associated infections across increasingly diverse care settings. As responsibilities expand, it is important to understand the evolution of workforce demographics, education, and roles.
Methods:
The 2025 Association for Professionals in Infection Control and Epidemiology (APIC) MegaSurvey was a cross-sectional, online survey of IPs. Survey development, pilot testing, and administration were led by APIC's Center for Research, Practice, and Innovation. Descriptive statistics and Cochran-Mantel-Haenszel tests were used to compare results with the 2015 and 2020 MegaSurveys.
Results:
Comparisons of the previous MegaSurvey results found significant differences in IP professional background, highest degree achieved, age range, gender, salary, certification, years of experience, and 5-year plans. More IPs (82%) reported a nursing background in 2015 and 2020, than IPs in 2025 (68%; P < .0001). Educational attainment increased, with 48% reporting a master's degree or higher in 2025 compared with 34% in 2015 (P < .0001).
Conclusions:
The IP workforce is becoming more diverse, specialized, educated, and distributed across settings. Ongoing monitoring, competency-based training, and strategic workforce planning are essential to sustain infection prevention capacity.
