Increase in False Positive Fourth Generation HIV Tests in Patients with COVID-19 Disease.

BACKGROUND: We observed an increase in the frequency of false positive (FP) HIV test results correlating with SARS-CoV-2 prevalence, which led us to measure FP rates of a laboratory-based fourth generation HIV antigen/antibody test among those with polymerase-chain reaction (PCR)-confirmed infection with SARS-CoV-2 compared to the FP rate of those testing PCR-negative for SARS-CoV-2. METHODS: All those PCR tested for SARS-CoV-2 result within 2 weeks of a HIV fourth generation assay were selected. Positive HIV fourth generation assays were independently reviewed and divided into groups of FP, true positives (TP), and presumptive negatives (PN). Variables included age, race, ethnicity, gender, pregnancy, and COVID-19 immunization status. Associations with positive SARS-CoV-2 tests were assessed using linear logistic regression. A multivariate logistic regression was used to assess sets of variables. RESULTS: There were 31,910 medical records that met criteria. The frequency of SARS-CoV-2 positive tests was then calculated in groups of HIV TP, FP, and PN. In total, 31,575 patients had a PN HIV test result, 248 patients had a TP, and 87 patients had a FP. Those with HIV FP tests had the highest percentage of COVID-19 positive test results at 19.5%, which was significantly higher than HIV PN (11.3%; p = 0.016) and HIV TP (7.7%; p = 0.002). After adjustment for all covariates, only FP HIV was significantly associated with COVID-19 (odds ratio 4.22; p = 0.001). CONCLUSIONS: This study reveals those patients with positive SARS-CoV-2 PCR tests are significantly more likely to have a FP fourth generation HIV test than those with negative SARS-CoV-2 PCR tests.

Descriptive Analysis of Patients Living With HIV Affected by COVID-19.

BACKGROUND: COVID-19 disease has spread globally and was declared a pandemic on March 11, 2020, by the World Health Organization. On March 10, the State of Michigan confirmed its first 2 cases of COVID-19, and the number of confirmed cases has reached 47,182 as of May 11, 2020, with 4555 deaths. SETTING: Currently, little is known if patients living with HIV (PLWH) are at a higher risk of severe COVID-19 or if their antiretrovirals are protective. This study presents epidemiologic and clinical features of COVID-19 infected PLWH in Detroit, Michigan. METHODS: This is a case series that included 14 PLWH with laboratory-confirmed COVID-19 infection who were evaluated at Henry Ford Hospital in Detroit, Michigan, between March 20, 2020, and April 30, 2020. RESULTS: Fourteen PLWH were diagnosed with COVID-19. Twelve patients were men and 2 were women; 13 patients were virally suppressed. Eight patients were hospitalized, and 6 patients were told to self-quarantine at home after their diagnoses. Three patients who were admitted expired during their hospital stay. No patient required bilevel positive airway pressure or nebulizer use in the emergency department, and none developed acute respiratory distress syndrome, pulmonary embolism, deep venous thrombosis, or a cytokine storm while on therapy for COVID-19. CONCLUSION: Although the clinical spectrum of COVID-19 among PLWH cannot be fully ascertained by this report, it adds to the data that suggest that HIV-positive patients with SARS-CoV-2 infection are not at a greater risk of severe disease or death as compared to HIV-negative patients.

The seroprevalence of COVID-19 in patients living with HIV in metropolitan Detroit.

BACKGROUND: COVID-19, a novel respiratory illness caused by SARS-CoV-2, has become a global pandemic. As of December 2020, 4.8% of the 941 people living with HIV in our Ryan White clinic have tested polymerase chain reaction positive for SARS-CoV-2. The aim of our study was to estimate the seroprevalence of COVID-19 in our Ryan White people living with HIV, irrespective of known past infection. METHODS: We conducted a cross-sectional study that recruited people living with HIV in the Ryan White program at Henry Ford Hospital in Detroit, Michigan, from September 2020 through May 2021. All Ryan White patients were offered participation during clinic visits. After informed consent, patients completed a survey, and had blood sampled for SARS-CoV-2 antibody testing. RESULTS: Of the 529 individuals who completed the written survey, 504 participants were tested for SARS-CoV-2 antibody and 52 people living with HIV were COVID-19 immunoglobulin (Ig) G positive resulting in a seroprevalence of 10.3%. Among 36 persons with PCR-confirmed COVID-19, 52.8% were IgG negative. Inclusion of PCR positive but IgG-negative people living with HIV yields a COVID-19 infection prevalence of 14.1%. CONCLUSIONS: These findings suggest that passive public health-based antibody surveillance in people living with HIV significantly underestimates past infection.

COVID-19 Pandemic and Catheter-associated Urinary Tract Infection Trends

Background It has been postulated that the COVID-19 pandemic would increase the overall catheter-associated urinary tract infections (CAUTI) risk in part due to higher acuity, increased indwelling urinary catheter (IUC) utilization, longer length of stay, changes in infection prevention practices due to staffing shortages. However, reported data are limited. The goal of this study was to evaluate the impact of the COVID-19 pandemic on our CAUTI rates. Methods This was a retrospective cross-sectional study comparing CAUTI rate per 1,000 indwelling urinary catheter (IUC) days, urine culture (UC) utilization rate per 1,000 IUC days, IUC utilization rate per 1,000 patient days, Standardized Infection Ratio (SIR) and Standardized Utilization Ratio (SUR) in the pre-COVID-19 period from January 1, 2019 to December 31, 2019 to the COVID-19 period from April 1, 2020 to March 31, 2021 at an 877-bed tertiary care hospital in Detroit, Michigan. CAUTI, UC utilization and IUC utilization rate were extracted from the electronic medical record (Epic™ Bugsy). SIR and SUR data were extracted from National Healthcare Safety Network (NHSN). Results The average CAUTI rate per 1,000 IUC days decreased from 0.99 pre-COVID-19 to 0.64 during COVID-19, yielding a 35% reduction. The UC order rate per 1,000 IUC days decreased from 19.19 to 18.83 with only 2% reduction. However, IUC utilization rate increased by 55% from 0.184 to 0.286. The SIR decreased from 0.483 to 0.337 with a 30% reduction, although this was not statistically significant ((P-value 0.283). The overall SUR decreased significantly from 0.806 to 0.762 (P-value < 0.001). Figure 2 is a control chart of the CAUTI rate from July 2019 to April 2021. Figure 1. CAUTI, indwelling urinary catheter and urine culture utilization rates pre-and during COVID-19 pandemic. Figure 2. CAUTI control chart pre-and during COVID-19 pandemic. Conclusion Although the IUC utilization increased during the COVID-19 pandemic, CAUTI rate, SIR and SUR decreased and UC orders remained unchanged. Thus, the pandemic did not have a negative impact on our CAUTI rates. Disclosures All Authors: No reported disclosures

Telehealth and HIV Care During the COVID-19 Pandemic

Background The COVID-19 Pandemic led to many restrictions in health care services, and as a consequence, an expansion of telehealth capabilities. In order to meet the needs of PLWH along the Care Continuum, we developed a process to promote the use of our MyChart app. This HIPAA-compliant app allows patients to view their medical records, communicate with their providers, make appointments, and have video visits on their smart devices. This report describes our preliminary findings. Methods PLWH enrolled in the Ryan White Program, in the Infectious Diseases Clinic at Henry Ford Hospital who had not used telehealth services were asked to sign up for our MyChart (electronic medical record software) initiative. A telehealth Navigator interviewed and taught PLWH how to download and use MyChart, and supplied pre-loaded phones, as needed, to make virtual visits accessible. We collected demographic and clinical information and reasons for not using telehealth services. Results From October 2020 to May 2021, 209 PLWH were enrolled into our pilot program (Table 1). Of these: 48% were 45-64 years old (yo), while 21% were >/+ 60 yo and 3% < 25 yo;75% were male, 85% Black;48% MSM, and 84% virally suppressed (HIV RNA < 200 copies/mm3). When asked why they were not using telehealth services, 29% reported a lack of technology or capability to install MyChart on their phones, 27% needed further education, and 18% and had not prioritized installation of the application. Conclusion The crises created by the COVID-19 pandemic revealed a new role for telehealth services. Although available to all PLWH in our RW program, many had never used telehealth services. Over half lacked compatible devices or needed help to download or use the app. Compared to younger PLWH, older individuals were more likely to need assistance. Further work is needed to understand and promote digital parity. Disclosures All Authors: No reported disclosures

Rapid Reorganization of an Academic Infectious Diseases Program During the Coronavirus Disease 2019 Pandemic in Detroit: A Novel Unit-based Group Rounding Model.

The surge of coronavirus disease 2019 (COVID-19) hospitalizations at our 877-bed quaternary care hospital in Detroit led to an emergent demand for Infectious Diseases (ID) consultations. The traditional 1-on-1 consultation model was untenable. Therefore, we rapidly restructured our ID division to provide effective consultative services. We implemented a novel unit-based group rounds model that focused on delivering key updates to teams and providing unit-wide consultations simultaneously to all team members. Effectiveness of the program was studied using Likert-scale survey data. The survey captured data from the first month of the Detroit COVID-19 pandemic. During this period there were approximately 950 patients hospitalized for treatment of COVID-19. The survey of trainees and faculty reported an overall 95% positive response to delivery of information, new knowledge acquisition, and provider confidence in the care of COVID-19 patients. This showed that the unit-based consult model is a sustainable effort to provide care during epidemics.
