The COVID-19 infection control response at a large stand-alone comprehensive cancer center in Los Angeles County.

BACKGROUND: The City of Hope National Medical Center (COH) is the only stand-alone comprehensive cancer center in Los Angeles, a county that was deemed a COVID-19 pandemic epicenter at the height of the 2020 winter surge. The immunocompromised patient population frequently experienced delays in infection control guidelines from local and government bodies due to minimal data available in comparison to the general population. This required COH to make swift, informed decisions for the best interest of the patient population. AIM: Here, we review the comprehensive COVID-19 infection control response conducted at COH within the context of a high-risk patient population, predominately comprised of patients with hematologic malignancies. METHODS AND RESULTS: This infection control response focused on prevention of COVID-19 transmission on campus, COVID-19 testing, and isolation management. These efforts consisted of COVID-19 screening, limitation of personnel on campus, source control, contact tracing, COVID-19 vaccination, establishment of in-house testing and implementation and management of COVID-19 testing. Between January 2020 and September 2021, COH implemented a robust in-house testing program, completed well over 1000 contact traces, ensured COVID-19 vaccinations were distributed to all eligible staff and patients, and established an algorithm for COVID-19 infection resolution, all without compromising the number of hematopoietic stem cell transplants (HCTs) performed, surgical volume, or healthcare-associated standardized infection ratios (SIR). CONCLUSION: Institutional collaboration and attention to infection control was pivotal to minimizing the burden of the COVID-19 pandemic.

Pandemic Operating Room Supply Shortage and Surgical Site Infection: Considerations as We Emerge from the Coronavirus Disease 2019 Pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic created shortages of operating room (OR) supplies, forcing healthcare systems to make concessions regarding "standard" OR attire. At our institution, we were required to reduce shoe covers, reuse face masks, and allow washable head coverings. We determined if these changes affected surgical site infection (SSI) rates. STUDY DESIGN: A single institutional study was performed to compare the SSI rates reported to the National Healthcare Safety Network in the 2 years preceding COVID-19 (PRE, January 1, 2018, to December 31, 2020) with the first 12 months after the pandemic (POST, April 1, 2020, to March 31, 2021). We confirmed our findings using propensity score matching and multivariate analysis. RESULTS: Elimination of traditional shoe covers, disposable head covers, and single-use face masks was associated with a decreased SSI rate from 5.1% PRE to 2.6% POST (p < 0.001). Furthermore, this was despite a 14% increase in surgical volume and an increase in the number of contaminated/dirty cases (2.2% PRE vs 7.4% POST, p < 0.001). Use of disposable face masks decreased by 4.3-fold during this period from 3.5 million/y PRE to 0.8 million/y POST. Of note, inpatient hand hygiene throughout the hospital increased from 71% PRE to 85% POST (p < 0.001). CONCLUSIONS: This analysis has practical applications as we emerge from the pandemic and make decisions regarding OR attire. These data suggest that disposable head covers and shoe covers and frequent changes of face masks are unnecessary, and discontinuation of these practices will have significant cost and environmental implications. These data also reinforce the importance of good hand hygiene for infection prevention.
