Study population: Adult COVID-19 patients discharged from all French hospitals from 01 February to 30 June 2020

Brief summary: Since March 2020, 3.5 million people have been infected with SARS-COV2 in France, and about 250 000 patients have been hospitalized and successfully discharged.

In a majority of cases, the evolution of the disease is favourable, but both hospitalized or patients with a mild form of the disease may present so called "Long-COVID" syndrome - a patient-created term which describes the effects of COVID-19 that continue for weeks or months beyond the initial symptoms. There is thus an urgent need to evaluate the long-term medical resource utilisation (MRU) and health care burden incurred by patients with Long-COVID, as well as risk factors for Long-COVID.

We will use the SNDS database to extract and analyze the data relevant to the project objectives. Indeed, the SNDS database is the French NHS database providing individual anonymous information of primary and secondary care linked at individual level (data from PMSI, the French DRG-based medical information system). It currently covers more than 98% of the French population.

For the first time, our study will provide an estimation of MRU and associated costs of hospitalized COVID-19 patients. It will also provide an estimation of the rate of long COVID forms developed by hospitalized COVID patients, as well as detailed MRU and costs incurred by long COVID patients compared to patients with non-long COVID-19.

Detailed description: Since March 2020, 3.5 million people have been infected with SARS-COV2 in France, and about 250 000 patients have been hospitalized and successfully discharged . Currently, the French epidemiological situation shows a stable and high level of new cases of COVID-19 (around 20 000 per day) and associated hospitalizations (around 9 000 per week).

COVID19 may present mild or severe forms, the latter possibly requiring conventional (20%) or intensive care unit (ICU) hospitalization (5%). In most cases, the evolution of the disease is favorable, but both hospitalized or patients with a mild form of the disease may present so called "Long-COVID" syndrome - a patient-created term which describes the effects of COVID-19 that continue for weeks or months beyond the initial symptoms. Persistent symptoms have been described in 5 to 36% of the patients, i.e. symptoms persisting for 4 weeks or more after the onset of the disease. There is growing evidence of the post-COVID-19 chronic syndrome as a postinfectious entity, including but not limited to a range of symptoms ranging from cough and shortness of breath, to fatigue, headache, palpitations, chest pain, joint pain, physical limitations, depression, and insomnia, persisting for longer than two months. This post-COVID chronic syndrome is often called "long COVID". As it is more and more described since the start of the pandemic, the French national health agency (Haute Autorité de Santé, HAS) has recently published specific recommendations for the management of patients presenting long COVID forms.

Although the evidence is still scarce, patients who have been hospitalized for COVID19 may be at higher risk of presenting long COVID. Consequently, they may require more healthcare resource use. As they are easy to identify through administrative databases, we propose to focus on hospitalized and discharged COVID-19 patients with persisting symptoms, in order to investigate their healthcare resource use and corresponding costs, and to compared them to patients not presenting the long COVID form of the disease.

The objectives of this study are:

1. to assess "long-COVID" patients' health care burden (costs) and resource use and to compare them to COVID patients not developing the long form of the disease
2. to identify predictive variables for the development of "long-COVID",
3. to investigate whether different patterns of long-COVID healthcare consumption may be identified.

This will be performed using the Système National des Données de Santé (SNDS) French medico-administrative database.
