A diffusion survey of coronary precautions

Nursing Research

|July 1, 1982

Summary

Despite evidence questioning their efficacy, common coronary care practices like restricting ice water and rectal temperature measurement persist in hospitals. Active intervention is needed to implement research findings into nursing care.

Area of Science:

Nursing Research
Cardiovascular Care
Evidence-Based Practice

Background:

Myocardial infarction (MI) patient care often involves restrictions, but their evidence base is sometimes questioned.
The adoption of research findings into clinical practice can be slow and inconsistent.

Purpose of the Study:

To describe current practices regarding restrictions for myocardial infarction (MI) patients in critical care units (CCUs).
To assess the diffusion of research findings related to MI care restrictions among nurses.

Main Methods:

A national cross-sectional survey of 240 accredited hospitals with CCUs was conducted.
A two-stage mailing survey targeted head nurses and randomly selected nurses, achieving an 87% response rate.
The 'Diffusion of Innovations' framework was used to analyze the adoption of research results.

Main Results:

Coronary precautions, including restricting ice water and rectal temperature measurement, are still commonly practiced despite evidence questioning their necessity.
Increased reading hours and journal readership correlated with higher nurse awareness of questioned restrictions (p < .001).
Nurse awareness levels did not correlate with the perceived importance or frequency of these restrictions.

Conclusions:

Passive dissemination of research findings is insufficient for changing established nursing practices.
Active intervention by nurse researchers and managers is crucial for the effective implementation of evidence-based care for MI patients.
