Objectives
Practicing antimicrobial stewardship in nursing homes faces many challenges, particularly in non-academic settings. We sought to identify features of community nursing home environments that are associated with lower rates of overall antibiotic use.
Design
In this pilot study, we used an explanatory sequential design that incorporated comparative feedback about antibiotic use to inform a discussion about antimicrobial stewardship practices among community nursing homes.
Measurements
For the quantitative phase, we measured the number of antibiotic prescriptions, length of therapy and days of therapy/1000 days of care at 6 nursing homes. For the qualitative phase, we conducted semi-structured interviews with healthcare workers in leadership positions at 5 community nursing homes. Transcripts from the recorded interviews were assessed using emergent thematic analysis. For the triangulation phase, we evaluated themes from the semi-structured interviews in the context of each NHs antibiotic use.
Results
The number of antibiotic prescriptions ranged from 172 to 1244, with 50% to 83% written for ≤ 7 days. All nursing homes reported a similar proportion of fluoroquinolone use (27–32% days of therapy). Triangulation yielded 6 themes for which the environment at each facility ranged from less to more supportive antimicrobial stewardship: practice patterns, external influences, infection control, leadership, communication and facility culture. All nursing homes reported pressure from well-intentioned family members to prescribe antibiotics. Nursing homes with shorter lengths of therapy and lower overall antibiotic use were consonant with an environment more supportive of antimicrobial stewardship.
Conclusion
Our findings suggest several features of nursing homes that are supportive of antimicrobial stewardship: practice patterns grounded in established diagnostic criteria, proactive infection control and prevention, open communication and interconnectedness among staff.
