Association of socioeconomic deprivation with outcomes in critically ill adult patients: an observational prospective multicenter cohort study.

Background: The influence of socioeconomic deprivation on health inequalities is established, but its effect on critically ill patients remains unclear, due to inconsistent definitions in previous studies.

Methods: Prospective multicenter cohort study conducted from March to June 2018 in eight ICUs in the Greater Paris area. All admitted patients aged ≥ 18 years were enrolled.

Hospitalizations for gastrointestinal and cardiovascular events in the CADEUS cohort of traditional or Coxib NSAID users.

Aims: To assess hospital admission rates for gastrointestinal (GI) or cardiovascular (CV) events in real-life use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Methods: CADEUS is a real-life population-based cohort study of 23 535 coxib (celecoxib or rofecoxib) and 22 919 traditional NSAID (tNSAID) users. Each hospitalization reported between index day (NSAID delivery) and questionnaire submission (median = 75 days) was explored using hospital discharge summaries.

Impact of prescriber nonresponse on patient representativeness.

Background: In pharmacoepidemiology studies where patients are selected by prescribers, there is concern that the patients of responding prescribers are not necessarily an unbiased sample of all patients. However, this usually cannot be explored. In the CADEUS study, patients and prescribers were independently contacted so that data are available for patients irrespective of whether their prescriber responded or not.

Channelling of COX-2 inhibitors to patients at higher gastrointestinal risk but not at lower cardiovascular risk: the Cox2 inhibitors and tNSAIDs description of users (CADEUS) study.

Purpose: To describe the characteristics of users of cyclo-oxygenase (COX)-2 inhibitors and traditional nonselective non-steroidal anti-inflammatory drugs (tNSAIDs) in France.

Methods: Between 1 August 2003 and 31 July 2004, patients who received at least one dispensing of celecoxib, rofecoxib or tNSAIDs were randomly sampled with a 1:1:2 target ratio within the French National Healthcare Insurance database. Patients and prescribers were asked to fill a questionnaire on socio-demographic characteristics, NSAID indication and use and previous medical history.
