824 - Isolation Rounding - Enforcing Existing Isolation Policies to Conserve Personal Protective Equipment

Background: During the COVID-19 pandemic, supplies of personal protective equipment (PPE) have been limited and sold at increased cost. Prior to the pandemic, we had initiated a project to improve PPE adherence and decrease cost by removing eligible patients from transmission based precautions (TBPs). At baseline, ordering providers are responsible for TBP utilization with orders through the electronic medical record. We observed that patients were in TBP when not indicated; remained in TBP beyond the appropriate time; and a reluctance on the part of providers to discontinue the orders. We tested the effect on TBP duration and PPE utilization house-wide through frequent review of TBP by a nurse educator with communication to providers of discontinuation opportunities.

Methods: From November 2019 to February 2020, all TBP orders in the pediatric intensive care unit (PICU) were reviewed intermittently. In March 2020, review was expanded to all inpatients with daily reviews in all units. Changes recommended and completed were tracked for all reviewed patients. We estimated cost of PPE in the PICU over time based on the number of patients in isolation and type of TBP utilized to determine whether our intervention resulted in reduced PPE use.

Results: Regular rounding in the PICU increased the proportion of patients in appropriate TBP and reduced the need to communicate with providers directly (33% vs 3% requiring intervention, Figure 1).  Over the same time period, less PPE was used and PPE-related costs lowered (average total PPE cost $306.18 vs $95.15 per day, Figure 2). Less of an effect was seen when analyzing house-wide data.Figure 1 - P-chart of Percent Interventions Among Patients in TBP

Conclusion: Isolation rounds is an effective means to ensure proper TBP adherence and manage PPE use appropriately. Additional study is needed to confirm a return on investment, to account for variation among units, and to sustain COVID-19-influenced gains beyond the pandemic.
