Intervention fidelity, particularly enactment, significantly improved care aide communication in nursing homes. This highlights the importance of how participants engage with interventions for better outcomes.
Area of Science:
- Healthcare research
- Nursing home quality improvement
- Behavioral intervention science
Background:
- Fidelity in complex behavioral interventions is often underexplored.
- The INFORM trial investigated care aide involvement in formal team communications.
- This study assessed the fidelity of the INFORM trial.
Purpose of the Study:
- To examine the fidelity of the INFORM trial intervention.
- To explore the relationship between fidelity, study arm, and care aide communication.
- To determine factors influencing the success of complex behavioral interventions in nursing homes.
Main Methods:
- A concurrent process evaluation of implementation fidelity was performed.
- The study included 33 nursing homes in Western Canada.
- 106 clinical care units were randomized to Basic and Enhanced-Assisted Feedback arms.
Main Results:
- Fidelity of the INFORM intervention was moderate to high.
- Fidelity enactment was higher in teams with greater improvement in formal team communications.
- Study arm was not associated with improvements in communication.
Conclusions:
- Intervention fidelity enactment, not study arm, correlated with improved formal team communications.
- The intensity of participant engagement with an intervention is crucial.
- Assessing and publishing fidelity results are vital for enhancing trial utility.
