Implementation Intentions as a Strategy to Increase the Notification Rate of Potential Ocular Tissue Donors by Nurses: A Clustered Randomized Trial in Hospital Settings

الملخص EN

Aim.

The purpose of this study is to evaluate the impact, among nurses in hospital settings, of a questionnaire-based implementation intentions intervention on notification of potential ocular tissue donors to donation stakeholders.

Methods.

This randomized intervention was clustered at the level of hospital departments with two study arms: questionnaire-based implementation intentions intervention and control.

In the intervention group, nurses were asked to plan specific actions if faced with a number of barriers when reporting potential ocular donors.

The primary outcome was the potential ocular tissue donors’ notification rate before and after the intervention.

Analysis was based on a generalized linear model with an identity link and a binomial distribution.

Results.

We compared outcomes in 26 departments from 5 hospitals, 13 departments per condition.

The implementation intentions intervention did not significantly increase the notification rate of ocular tissue donors (intervention: 23.1% versus control: 21.1%; χ2=1.14, 2; P=0.56).

Conclusion.

A single and brief implementation intentions intervention among nurses did not modify the notification rate of potential ocular tissue donors to donation stakeholders.

Low exposure to the intervention was a major challenge in this study.

Further studies should carefully consider a multicomponent intervention to increase exposure to this type of intervention.
