Influence of socioeconomic status on antipsychotic prescriptions among youth in France

Abstract

BackgroundRecent studies analysing the trends in antipsychotic (AP) prescriptions for children and adolescents have raised concerns regarding the influence of socioeconomic status. Previous findings have also shown variable prescription rates for first-generation (FG) and second-generation (SG) APs.MethodOur objectives were to assess the proportion of patients from low-income families receiving APs and the most commonly prescribed APs in France. We conducted a descriptive analysis of AP drugs dispensed during a 1-year period (July 1, 2013–June 30, 2014) in a northwestern region of France with 941,857 subjects less than 18 years old. All data were extracted from an exhaustive, individual and anonymous social security database. We obtained each subject’s socioeconomic status (by identifying their affiliation with a specific social security program) and also collected sociodemographic data, drug type, prescribing and dispensing dates and amount, and prescriber type (e.g., hospital physician, general practitioner, psychiatrist, paediatrician).ResultsThere were two main novel findings. First, we found that the proportion of patients with AP prescriptions was nearly ten times higher in low-income families than in the general population: 35.9% of CMU-C patients compared to 3.7% in all of Pays de la Loire (X 2 = 7875.1, p < 0.001). Additionally, we found a higher rate of FGAP than SGAP prescriptions (65% vs. 57%).ConclusionsOur study suggests two types of AP misuse that could provide interesting targets for public healthcare interventions.First, our results strongly suggest an over-representation of patients from low-income families. Low-income families primarily resided in areas with low physician density and appeared to receive drugs to treat their conditions more frequently than other individuals. This increased prescription rate is a public health issue, potentially requiring political action. Second, the use of FGAPs did not adhere to the latest recommendations for drug use in this population, and this discrepancy should be addressed with informational campaigns targeted to medical practitioners.

Comparison of antipsychotic drug use among Dutch Youth before and after implementation of the Youth Act (2010–2019)

“…Second, the IADB database only includes parts of the Netherlands, representing mainly less urbanized areas. Some literature suggests antipsychotic drug prescriptions might decrease with greater medical density [28]. Hypothesizing that urban regions contain more medical facilities, this might have led to an overestimation of the prescription rates found in our study.…”

Unraveling ethnic disparities in antipsychotic prescribing among patients with psychosis: A retrospective cohort study based on electronic clinical records

“…We also included variables on history of substance use, socioeconomic status and neighbourhood ethnic density, given their associations with prescription of antipsychotics ( Bonnot et al, 2017 ; Foglia et al, 2017 ; Termorshuizen et al, 2018 ). Cannabis use, one of the most commonly used illicit substance among those with psychosis ( Foglia et al, 2017 ), was extracted via NLP and recorded as a binary variable representing whether or not there was evidence of cannabis use recorded in EHR.…”

“…Their mission was to guarantee the scientific validity of the work and define all data selection that were made, interpret results, as well as to define therapeutic changes that may be indicative of a worsening of patients’ clinical states. Our scientific committee already with this register and using this specific methodology ( Bonnot et al, 2017 ; Bulteau et al, 2021 ).…”
