Dire Numbers of Covid-19 Cases and Fatalities in Nursing Homes

Our data analysts recently examined a Medicare data file containing medical claims records of Covid-19 patients who reside in nursing homes. The file contained all U.S. patient cases as of June 7, along with records related to nursing home staff with the coronavirus. Most disturbing were the numbers of fatalities and the corresponding fatality rate, as most of these elderly patients also had underlying health issues that put them at a much higher risk for a serious bout of the disease.

Tracking the Spread of Active Covid-19 Cases Across the Country

We continue our analysis of Covid-19 data reported by state and local health agencies with a look at Active Cases: the number of cases reported by the state during the prior 14 days. We also look at the number of coronavirus tests administered by a state, it's ratio to the number of diagnosed cases, and the TcP ratio's use in forecasting Covid-19 cases. Explore our findings.

Commercial and Medicare Covid-19 Patient Co-Morbidities

We return to our analyses of medical claims records with a special focus on the chronic diseases identified by the CDC as the most troublesome for Covid-19 patients, including comparisons between patients on commercial insurance and older patients on Medicare. After tallying the numbers and percentages of these co-morbidities in Covid-19 claims records database, we also compare those figures to co-morbidities found in 100,000 records randomly selected from 2019 commercial claims.

Coronavirus Cases, Hospitalizations, Tests, and Recoveries by State by Pop.

This week we take a look at the coronavirus data reported by U.S. county and state health agencies since the beginning of April. We compare the number cases for each state by looking at the ratio of cases per 100,000 population. We also look at the fatality rate by state, specifically the ratio of diagnosed cases that end in death. Finally, we examine each state's daily average of new cases by month to determine where a state stands as they evaluate restrictions and the reopening of their economies.

Service Line Management Trends in Covid-19 Cases

As the number of claims records related to Covid-19 patients increases in our database, we are starting to see patterns emerge that shed new light on the bodily systems affected by this disease. In addition, by analyzing the volumes of cases by diagnosis code category, type, and especially by service line, we are able to  gauge the impact of Covid-19 on the hospitals and providers that care for these patients.

Making the Connection between Coronavirus Cases and Claims

In this week's analysis, we continue to track the increases in medical claims records for suspected and confirmed Covid-19 patients. After an initial period for the claims to reflect the new diagnosis codes, we saw a decrease in the number of suspected cases as confirmed cases increased in the U.S. We also tracked the progression of the U.S. population as more patients were diagnosed with the coronavirus. Review our findings.

Evaluation and Management Codes for Covid-19 Patients

Our deep dive into COVID-19 patient medical histories this week quantified the top ten Evaluation / Management and Procedure codes used during provider visits. The data also illustrates the growing use of telemedicine with a pediatrician and a national service. Read more.

Initial Insights into Covid-19 Patients from Medical Claims Data

In addition to our interactive map of Covid-19 cases across U.S. counties, and our state-wide projections, our data analysts went further and examined the medical histories of de-identified Covid-19 patients. Within the data they found intriguing information that we've compiled into the following data briefs. The first brief sets forth the methodology and some of the initial findings.
