The field of infection prevention is rapidly evolving and becoming increasingly complex, as resource-intensive responses to device-associated outbreaks, global epidemics, and regulatory requirements continue to grow. This increasing complexity coupled with changing health care systems present important challenges to infection prevention staffing and resources. We describe the development of a novel infection prevention and control (IPC) staffing structure that includes both infection preventionists (IPs) and role-specific support staff to meet the evolving IPC needs and challenges of an expanding health care network.

The IPC department at Children's Hospital of Philadelphia underwent iterative modifications to its staffing structure between 2014 and 2018, including the development of revised job descriptions and promotional criteria, career ladders, and supporting roles. Data on key infection prevention activities, including rounding frequency and performance of audits and observations, growth metrics and infection data was evaluated for trends before and after departmental restructuring. An overall health care associated infection (HAI) index was calculated based on existing surveillance data and used to monitor patient outcomes over time. In addition, departmental employee engagement was assessed via a standard survey instrument to evaluate improvements in teamwork and professional growth opportunities over time.

Between 2014 and 2018, the number of unique job descriptions for IPs and support staff increased from 4 to 9, creating a 3-tier career ladder for IPs and increasing full time equivalents from 8.2 to 11.6. Additional support roles included a Hand Hygiene Program Manager, Infection Prevention Associates and a Clinical Practice Analyst; these roles, along with increased IP staffing, expanded the education and consultative range of the department, as measured by a 33% increase in environmental rounding and a 7-fold increase in performance of isolation audits. Team diversity also expanded, changing from a team with predominantly nursing backgrounds, to one with an equal distribution of nursing, public health, and laboratory scientists. Results from serial engagement surveys showed an increase in teamwork and professional growth by 7.4% and 5.4%, respectively. Over this time period, the total HAI index decreased by 23%, while patient days, central line days, and ventilator days increased each year, and there was a statistically significant reduction in rates of harm across 5 key HAI indicators.

Role diversity and varying professional backgrounds within IPC programs offer a complement of strengths and increase capacity to support patient care activities, improving patient outcomes. This strategy leads to a more cost-effective, robust IPC program that supports the growing needs and evolving challenges of the field.
