Comparing the delirium objective structured clinical examination (OSCE) education package to standard education for post-registration nurses: A randomised controlled trial.

BACKGROUND

A recent pilot study demonstrated that an interactive delirium educational intervention, The Delirium OSCE Education Package, had a positive impact on self-perceptions of confidence and competence in the use of delirium assessment tools and delirium knowledge; delirium knowledge scores; clinical practice; and planned practice change for participants. However, it is not known if The Delirium OSCE Education Package is superior to standard methods of professional development education.

OBJECTIVE

To determine if The Delirium OSCE Education Package is superior to standard methods of professional development education on observations of delirium care in practice scores for post-registration nurses.

DESIGN

Clustered randomised, controlled, and observer-blinded, multisite superiority trial with two parallel groups at each site.

SETTINGS: Three private hospitals across New South Wales, Australia.

PARTICIPANTS

Registered nurses (RNs) (n = 153) or enrolled nurses (ENs) (n = 37) working in the eligible inpatient medical or surgical wards at each site.

METHODS

Within each hospital site wards were clusters, with wards rather than individuals being randomised for The Delirium OSCE Education Package or standard professional development education at a ratio of 1:1. The primary outcome was observations of delirium care in practice, 6-weeks post (T1) allocated intervention. Secondary outcomes were self-perceived confidence and competence (self-efficacy) in delirium assessment tools and delirium knowledge; and delirium knowledge scores.

RESULTS

A total of 51.3 % (n = 20) in the intervention group obtained a satisfactory observation of delirium care in practice score, compared to 34.9 % (n = 15) in the control group (p = 0.134, χ2). The odds of a satisfactory observation of delirium care in practice score for the intervention group was 10.1 times higher than the control (p = 0.009). The mean MCQ score and perceptions of confidence and competence in the intervention and control group increased from baseline to six-weeks post-intervention, however, there was no significant difference between the groups.

CONCLUSION

The Delirium OSCE Education Package provides the foundation for facilitating change in delirium care. It is recommended that The Delirium OSCE Education Package is implemented as part of a multicomponent strategy involving a validation delirium screening and assessment tool, hospital-specific policy, interprofessional education, and delirium champions. Future studies are needed to evaluate the sustainability of the intervention and if there is a positive impact on patient-level outcomes.
