RESUMO
BACKGROUND: Isolation of patients with multidrug-resistant organisms has been recommended in several guidelines. Recent evidence has suggested potential negative effects of isolation on patient well-being and facility throughput. Published literature shows a difference in transmission risk of extended-spectrum ß-lactamase (ESBL)-producing organisms, suggesting that contact precautions may not be necessary for all ESBL-positive organisms. METHODS: Incidence rates of health care-associated ESBL organisms were measured before and after eliminating the use of contact precautions for patients with only ESBL-positive organisms. The National Healthcare Safety Network surveillance methodology was used to measure incidence. Surgical site infections and carbapenem-resistant Enterobacteriaceae were excluded from the surveillance incidence. RESULTS: The incidence of health care-associated ESBL infections from January 2014 through November 2015 was 3.71 per 10,000 patient days. The incidence from December 2015 through August 2017 was 3.00 per 10,000 patient days. This rate change was statistically significant (Pâ¯=â¯.022) CONCLUSIONS: This study found that discontinuing the use of contact precautions for patients colonized or infected with ESBL-positive organisms did not lead to an increased rate of health care-associated ESBL-positive infections or colonization.
