Objectives: To our best knowledge, no study in France has comprehensively investigated the prehospital history of patients admitted for severe cases of COVID-19. 'Patients' voice is an excellent means to capture data on primary care pathways. We aimed to identify clusters of COVID-19 hospitalised patients with similar prehospital symptom sequences, and to test whether these clusters were associated with a higher risk of poor clinical outcomes. Design: Cross-sectional online survey using life-event calendars. Setting: All patients hospitalised for COVID-19 between September 2020 and May 2021 in the Infectious Disease Departments in Nice and in Marseilles in France. Participants: 312 patients responded to the survey. Main outcome measures: From the day of symptom onset to the day of hospitalisation, we defined a symptom sequence as the time-ordered vector of the successive symptom grades (grade 1, grade 2, grade 3). State sequence analysis with optimal matching was used to identify clusters of patients with similar symptom sequences. Multivariate logistic regressions were performed to test whether these clusters were associated with admission to intensive care unit (ICU) and COVID-19 sequelae after hospitalisation. Results: Three clusters of symptom sequences were identified among 312 complete prehospital pathways. A specific group of patients (29%) experienced extended symptoms of severe COVID-19, persisting for an average duration of 7.5 days before hospitalisation. This group had a significantly higher probability of being admitted to ICU (adjusted OR 2.01). They were less likely to know a loved one who was a healthcare worker, and more likely to have a lower level of education. Similarly, this group of patients, who were more likely to have previously visited the emergency room without exhibiting severe symptoms at that time, may have been inclined to postpone reassessment when their health worsened. Their relatives played a decisive role in their hospitalisation. [ABSTRACT FROM AUTHOR]

Since several years, the use of intravenous immunoglobulins (IVIg) has increased. This growth has encouraged some countries to publish guidelines. In parallel, some countries have conducted audits to know how IVIg are used in clinical practice in the light of the available guidelines. The objective of this study was to assess IVIg use in three French university hospitals in 2006. All IVIg administrations were evaluated during 6 months (12 September 2005-12 March 2006) in French university hospitals of Marseille. Different data were recorded for each administration: patient characteristics, indication, formulation and quantity. During the study period, 2802 administrations of IVIg (corresponding to a total quantity of 76 780 g) have been recorded. Four hundred and thirty-five patients received at least one of these administrations. The five most reported indications were multifocal motor neuropathy (11.0% of total quantity), chronic inflammatory demyelinating polyradiculoneuropathy (10.2%), corticoresistant dermatomyositis (10.2%), immune thrombocytopaenia (9.9%) and primary immune deficiency (9.1%). According to available French recommendations, 70% of the IVIg use was for 'acknowledged indications', 9% for 'indications to be assessed' and 18% for 'unwarranted indications'. The 10 most reported indications were 'acknowledged indications' according to available recommendations of the French expert group. Nevertheless, the two most reported indications were not approved by the French Health Products Agency (AFSSAPS) at the time of the study and were approved since. [ABSTRACT FROM AUTHOR]
