Analysis of a nurses' knowledge survey on the use of physical restraint in intensive care units

Abstract

Objectives: To determine nurses' knowledge level regarding physical restraint use in intensive care units and its associated factors.

Method: A cross-sectional multicentre study was carried out in 12 critical care units of 8 hospitals in Spain (n=354 nurses). An 'ad-hoc' knowledge survey was developed, and their content was validated by experts. The survey obtained a test-retest stability of ICC=.71 (95% CI: .57-.81) in a previous pilot study. A final 8-item tool was designed. Sociodemographic and professional variables from the participants were collected; as well as structural and clinical variables from the units analyzed. A descriptive and association analysis between variables was performed. A p-value <.05 was deemed statistically significant.

Results: Two hundred and fifty nurses answered the survey (70.62%). Mean age of the participants was 36.80 (SD 9.54) with 10.75 (SD 8.38) years of professional experience in critical care. Seventy-three point six percent had never received previous training about physical restraints. Knowledge mean value was 4.21 (SD 1.39) (range 0-8). Knowledge level was associated with the referral hospital (p<.001). Nurses with a higher knowledge level are more likely to work in units with informed consent sheets for physical restraint use (p<.001); flexible family visiting (p<.001); analgo-sedation protocol (p=.011), and units in which nurses had autonomy to manage analgo-sedation (p<.001). Individual sociodemographic and professional data was not associated with knowledge level.

Conclusions: Further training regarding physical restraint use is needed for critical care nurses. The work environment where nursing care is given has a great influence on nurses' knowledge level about this intervention.
