Abstract

Objective:

To investigate compliance with isolation precautions.

Design:

A prospective observational study carried out during ten weeks of 1989. Participants were unaware of the study.

Setting:

The isolation bay of a 24-bed surgical intensive care unit in a 900-bed university tertiary care facility.

Participants:

Study participants included any healthcare worker or visitor entering the patient room during designated 15-minute intervals.

Results:

We observed 467 subjects entering patient rooms. Compliance with strict isolation (65%) was better than with wound/skin (40%) or excretion/secretion (36%) isolation (p<.01). Visitors were more compliant than healthcare workers (88% versus 41%; p<.01). Spending more time in the room was associated with improved compliance (p<.01). Compliance was higher for subjects entering with a group compared with those entering alone (51% versus 41%; p<.05). The compliance rate for nurses improved as the nurse/patient ratio improved (p= .14). Compliance was independent of severity of illness. Multivariate analysis revealed that the amount of time spent in the room, being a visitor, and use of strict isolation were independent predictors of compliance.

Conclusions:

Noncompliance was wide-spread. When increased demands are placed on the time of physicians and nurses in the name of cost containment, unperceived consequences, such as those resulting from decreased compliance, must be considered.
