Association between COVID-19 and Delirium Development while Hospitalized in the General Medical Units at an Academic Medical Center
Overview
We examined 1) the association between COVID-19 diagnosis and incidence of delirium among patients admitted to acute care units, and 2) factors associated with the incidence of delirium among patients admitted with COVID-19.
Key Learnings & Impact
- There were no COVID-19 specific symptoms that are associated with developing delirium
- COVID-positive patients had 62% higher relative risk of developing delirium than COVID-negative patients
- Among COVID-positive patients, development of delirium was associated with male sex and age >60
- COVID-19 positive patients above age 60 are especially vulnerable for delirium and may benefit from extra screening for this often-under-recognized condition
Results Dissemination
- Oral presentation at Society of General Internal Medicine Annual Meeting, April 2022
- Manuscript preparation underway

Racial Disparities in Incidence and Outcomes Among Patients With COVID-19
Overview
We assessed COVID-19 positivity, hospitalization, intensive care unit admission, mechanical ventilation, and death among various racial groups, in addition to other important demographic factors, to learn the impact of these social determinants of health early in the COVID-19 pandemic.
Key Learnings & Impact
- Black race was associated with COVID-19 positivity
- Black race and poverty were associated with hospitalization due to COVID-19
- Poverty, but not Black race, was associated with ICU admission due to COVID-19
Results Dissemination
- Results published in JAMA Network Open, September 2020

Decrease in Positivity Rate of Influenza Tests Coinciding With Outbreak of SARS-CoV-2: Data From a Southeastern Wisconsin Laboratory
Overview
Using laboratory data, we assessed the total number of weekly flu tests and test positivity rates during the 2019-2020 flu season 鈥� coinciding with the start of the COVID-19 pandemic 鈥� with previous flu seasons.
Key Learnings & Impact
- Flu positivity rates declined to 0% more quickly than in any of the 4 previous years
- 0% positivity was achieved 8 weeks ahead of the next earliest 0% positivity year: during the 2nd week of April (2019-2020) vs. during the final week of May (2017-2018)

The Impact of COVID-19 Viral Load at Admission
Overview
We studied whether patient demographics (race & poverty) were associated with varying COVID-19 viral loads at hospital admission. We also assessed if viral load was an indicator of length of stay and discharge disposition.
Key Learnings
- A higher COVID-19 viral load was associated with a longer length of stay and higher likelihood of death, but was not associated with discharge to SNF
- After accounting for viral load, poverty was associated with discharge to a SNF

- Results published in the Wisconsin Medical Journal, December 2021

Hospitalization Outcomes Among Patients With COVID-19 Undergoing Remote Monitoring
Overview
We evaluated a daily remote patient monitoring (RPM) program for patients diagnosed with COVID-19 and are managing symptoms from home. We assessed whether patients managed with RPM were more likely to be admitted to the hospital compared to those not monitored.
Key Learnings & Impact
- Patients managed through RPM had a 30% lower odds of hospitalization
- Of hospitalized patients, those managed through RPM sought care escalation later than those not managed; however, RPM patients had a shorter length of stay and were less likely to be admitted to the ICU
