527. Project “Isolation Zero”: Discontinuing Contact Precautions for Patients Colonized/Infected with Multidrug-Resistant Organisms through Community-Level Follow-Up in Spain

Background In an effort to prevent and control the spread of multidrug-resistant organisms (MDROs), hospitals implement contact precautions (CP) for patients colonized/infected with MDROs. All agencies related to the prevention and control of infections recommend this practice, but they also recognize that is not exempt from unintended consequences. In 2017, SHEA published an expert guideline where they provide recommendations for discontinuation of CP. Currently, the most accepted recommendation is to perform at least one microbiological culture prior to discontinuing CP. The main objective of this project is to implement and evaluate a novel community -level approach to safely discontinue CP in patients with a history of colonization/infection with an MDRO. Methods The “Isolation Zero” project (IZ) was rolled out in November 2018 in the healthcare area of A Coruña, Spain. All clinical records of patients included in the MDROs alert system between 2005–2012 in A Coruña were reviewed. Patients included in the study were those who reside in the healthcare area of A Coruña and did not have any positive microbiological culture for MDROs in the last 2 years (Figure 1). Those who met the inclusion criteria were sent a letter suggesting that they obtain a nurse consultation in the next 2 months and that they provide specific MDRO cultures (Figure 2). Finally, the Department of Preventive Medicine (PM) reviewed all the results and identified patients for which CP could be safely discontinued in future hospitalizations. Results A total of 792 clinical records were reviewed (Table 1). 184 patients met the inclusion criteria. The response rate was 60.3% (111 patients). The most frequent MDRO tested was MRSA (84.8%), followed by MDR Acinetobacter (7.6%). CP were withdrawn for a total of 83 patients, while 15 patients continued to test positive (Table 2). Conclusion These results suggest that even after more than 2 years without a positive result, 13,5% of patients remain positive for MDROs. Therefore, in order to safely minimize the use of CP, we conclude that an approach similar to that used in IZ is a good option for PM Departments. Follow-up at the community -level can help reduce the number of hospital isolations required and can help improve the overall quality of care. Disclosures All authors: No reported disclosures.
