OASIS: Building a Novel Antibiotic Stewardship Intervention for Nursing Homes
Study Details
Study Description
Brief Summary
The OASIS Collaborative is an organizational intervention aimed at reducing unnecessary antibiotic use in skilled nursing facilities. The first target of intervention is the tasks carried out by nursing staff after a change in condition and after an antibiotic prescription is initiated. The second target are the management staff who provide feedback to staff. The third target are the administrators who identify and overcome organizational barriers to implementation.
In this study, we will implement two tools that are intended to minimize unnecessary antibiotic use in skilled nursing facilities. The first tool helps skilled nursing facility staff assess risk and communicate with prescribers when residents experience a change in health status that may result in the use of antibiotics. The second tool is used after an antibiotic is prescribed; the tool streamlines reassessment of the patient, and provides prescribers the opportunity to consider stopping unnecessary antibiotic prescriptions, narrowing the spectrum of antibiotic therapy, or shortening the duration of antibiotic therapy.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: OASIS Collaborative The nursing homes in this arm will receive facilitated implementation of two tools aimed at minimizing unnecessary antibiotic use. Facilitated implementation includes coaching of the nursing home staff on use of the tools. In addition, nursing home management will be coached on how to monitor implementation fidelity, antibiotic utilization, and consequences to over- and under-utilization of antibiotics as feedback on the effectiveness of the intervention. Finally, nursing home management will receive coaching on how to develop and implement a sustain plan for the OASIS intervention. |

| No Intervention: Control The nursing homes in this arm will continue care as usual, with no tools or facilitated implementation. |
Outcome Measures
Primary Outcome Measures
- Days of Antibiotic Therapy (DOT)/1000 resident days [up to 12 months]
Utilization of antibiotics initiated in the nursing home, defined as the number of days a nursing home resident receives antibiotic therapy. This measure includes antibiotic courses initiated 1) in the nursing home or 2) Emergency Department, if the resident returned to the nursing home without intercurrent hospitalization. This measure excludes antibiotic courses started during a hospital stay and continued in the nursing home after discharge.
- Proportion of Antibiotic Starts meeting Loeb Criteria [up to 12 months]
Defined as the proportion of antibiotic courses started in the nursing home or Emergency department that satisfy the Loeb minimum criteria for initiation of antibiotics. This measure includes antibiotic courses initiated 1) in the nursing home or 2) Emergency Department, if the resident returned to the nursing home without intercurrent hospitalization. This measure excludes antibiotic courses started during a hospital stay and continued in the nursing home after discharge.
Secondary Outcome Measures
- Incidence of antibiotic starts/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the number of antibiotic courses started per 1000 resident days. This measure includes antibiotic courses initiated 1) in the nursing home or 2) Emergency Department, if the resident returned to the nursing home without intercurrent hospitalization. This measure excludes antibiotic courses started during a hospital stay and continued in the nursing home after discharge.
- Fluoroquinolone Days of Therapy (FQD)/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the number of days a nursing home resident receives fluoroquinolone therapy. This measure includes antibiotic courses initiated 1) in the nursing home or 2) Emergency Department, if the resident returned to the nursing home without intercurrent hospitalization. This measure excludes antibiotic courses started during a hospital stay and continued in the nursing home after discharge.
- Incidence of C.diff infection/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the number of positive C. difficile tests per 1000 resident days
- Fluoroquinolone resistance [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the proportion of urine cultures that grow bacteria that are resistant to fluoroquinolone antibiotics.
- Positive Enterococcus species [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the proportion of urine cultures that grow Enterococcus species
- Positive Candida species [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the proportion of urine cultures that grow Candida species
Other Outcome Measures
- Incidence of nursing home deaths/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Includes deaths that occur in 1) the nursing home or 2) the hospital if a resident's bed is kept on hold at the nursing home.
- Incidence of unplanned transfers/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Includes unplanned transfers to 1) the hospital or 2) the emergency room that do not result in hospitalization. This measure excludes planned transfers (e.g., physician clinic visits) or hospitalizations (e.g., for a planned surgical procedure or other therapy).
- Combined deaths and unplanned transfers/1000 resident days [up to 12 months pre-implementation and up to 12 months post-implementation]
Defined as the sum of deaths and unplanned transfers, as defined above.
