Teamwork by a wide range of professional staff, coupled with support from leadership, enabled one academic community hospital to cut its rate of hospital-onset Clostridioides difficile infections (HO-CDIs) by almost two-thirds in 1 year and by over three-quarters in 3 years, a study published in the American Journal of Infection Control reports.
C. diff. is a major health threat. According to the U.S. Centers for Disease Control and Prevention, CDIs, mainly linked with hospitals, caused an estimated 223,900 cases in hospitalized patients and 12,800 deaths in the United States in 2017.
“The interventions and outcomes of the project improved patient care by ensuring early testing, diagnosis, treatment if warranted, and proper isolation, which helped reduce C. diff. transmission to staff and other patients,” lead study author Cherith Walter, MSN, RN, a clinical nurse specialist at Emory Saint Joseph’s Hospital, Atlanta, told this news organization. “Had we not worked together as a team, we would not have had the ability to carry out such a robust project,” she added in an email.
Each HO-CDI case costs a health care system an estimated $12,313, and high rates of HO-CDIs incur fines from the Hospital-Acquired Condition Reduction Program of the Centers for Medicare & Medicaid Services (CMS), the authors write.
A diverse staff team collaborated
Emory Saint Joseph’s, a 410-bed hospital in Atlanta, had a history of being above the national CMS benchmark for HO-CDIs. To reduce these infections, comply with CMS requirements, and avoid fines, Ms. Walter and colleagues launched a quality improvement project between 2015 and 2020.
With the approval of the chief nursing officer, chief quality officer, and hospital board, researchers mobilized a diverse team of professionals: a clinical nurse specialist, a physician champion, unit nurse champions, a hospital epidemiologist, an infection preventionist, a clinical microbiologist, an antimicrobial stewardship pharmacist, and an environmental services representative.
The team investigated what caused their hospital’s HO-CDIs from 2014 through 2016 and developed appropriate, evidence-based infection prevention interventions. The integrated approach involved:
- Diagnostic stewardship, including a diarrhea decision-tree algorithm that enabled nurses to order tests of any loose or unformed stool for C. diff. during the first 3 days of admission.
- Enhanced environmental cleaning, which involved switching from sporicidal disinfectant only in isolation rooms to using a more effective Environmental Protection Agency–approved sporicidal disinfectant containing hydrogen peroxide and peracetic acid in all patient rooms for daily cleaning and after discharge. Every day, high-touch surfaces in C. diff. isolation rooms were cleaned and shared equipment was disinfected with bleach wipes. After patient discharge, staff cleaned mattresses on all sides, wiped walls with disinfectant, and used ultraviolet light.
- Antimicrobial stewardship. Formulary fluoroquinolones were removed as standalone orders and made available only through order sets with built-in clinical decision support.
- Education of staff on best practices, through emails, flyers, meetings, and training sessions. Two nurses needed to approve the appropriateness of testing specific specimens for CDI. All HO-CDIs were reviewed and findings presented at CDI team meetings.
- Accountability. Staff on the team and units received emailed notices about compliance issues and held meetings to discuss how to improve compliance.
