A lack of infection prevention and control staffing leads to more healthcare-associated infections, according to a new study in the American Journal of Infection Control. Researchers analyzed the infection preventionists (IPs) staffing needs at 390 acute care hospitals and the number of optimal IPs was based on factors such as the presence of an emergency department, burn unit, stem cell transplant unit, or inpatient rehabilitation unit. The majority of the 390 hospitals surveyed (79.2%) were understaffed according to the calculator in infection control personnel, which assumed a baseline staffing level of 1 full-time IP per 85 beds. Overall, the median IP full-time equivalent to bed ratio was 121.0 beds for the 390 hospitals.
