Evaluation of a medically coordinated care program in the management of autism.

Autism spectrum disorders (ASD) are neurodevelopmental disorders of varying intensity and disability. The reference health strategy in France for the care of young children with autism is day care hospital (DCH). As the number of places in DCH is insufficient, medically coordinated care programs by the mental health consultation centers (MHCC) are being developed in response. OBJECTIVES: Our objective is to evaluate the effectiveness of a medically coordinated care program in a MHCC versus the care in DCH of child psychiatry. METHODS: Non-inferiority retrospective study comparing the evolution after one year of care of 20 ASD children divided into two groups DCH and MHCC. In the DCH ASD group, the child is taken care of two half-days a week in a day hospital with individual educational care. In the MHCC ASD group, the child benefits from a medically coordinated care program. The medical care is reinforced by more frequent and longer consultations with guidance offered to parents. In both groups, the child receives speech therapy and psychomotor therapy in private practice at the same rate. Comparison is made using a composite criterion associating CARS-2 and VABS-II. Non-inferiority of the medically coordinated care program in autism in reference to DCH was tested on the difference between the changes (DCH group variation - MHCC group variation) with a non-inferiority threshold of 10% of the initial value of each score. RESULTS: We observed a reduction in autism severity at the CARS-2 and a moderate improvement in socio-adaptive behavior at the VABS-II in both groups. This trend was even more pronounced in the MHCC group than in the DCH group, but only the greater reduction in CARS-2 severity in the MHCC was statistically significant. CONCLUSIONS: As it is necessary to integrate the two scales into the composite criterion, it is not possible to retain the non-inferiority of the MHCC with care program. However, both those children followed in DCH and those in the MHCC care program progress. This shows the relevance of the care offered at the MHCC for children suffering from ASD, in the context of a growing lack of space in DCH. The continuation of this research work through multicenter studies with larger numbers could demonstrate the non-inferiority of coordinated care programs in the MHCC versus DCH. It would also allow subgroups to be set up, taking into account the initial characteristics of the children in order to have more precise indications concerning the relevance of each treatment.

Patterns of Pregabalin Users from Substance Abuse Treatment Facilities: Results from the French OPPIDUM Program from 2008 to 2022.

INTRODUCTION: In recent years, pregabalin has received growing attention due to its abuse liability. The aim of this study was to further characterize patterns of pregabalin users from substance abuse treatment facilities and detect changes in users profile over the study period. METHODS: The data source was the Observation des Produits Psychotropes Illicites ou Détournés de leur Utilisation Médicamenteuse (OPPIDUM) program, an annual, repeated, cross-sectional, nationwide, multicenter survey that collects consumption data from patients with substance use disorders. First, we described the characteristics of pregabalin users and their consumption patterns. We compared these data between 2008 and 2018 (P1) and 2019 and 2022 (P2). Second, we conducted a multiple correspondence analysis to identify profiles of users. RESULTS: From 2008 to 2022, 291 pregabalin users (0.37% of all users) from 116 substance abuse treatment facilities were identified. The number of pregabalin users was lower than 15 per year in P1 (n = 89) and between 40 and 60 per year in P2 (n = 202). The number of users who reported pregabalin as the first substance leading to dependence increased significantly in P2 compared with P1 (p < 0.005). When comparing P2 with P1, there was a significant increase in precarity (p < 0.001), users in prison (p = 0.002), withdrawal symptoms (p < 0.001), dependence (p < 0.001), use of higher dose of pregabalin (p = 0.029), and acquisition by deal/street market (p < 0.001). The multiple correspondence analysis allowed for the identification of distinct profiles of pregabalin users: (i) a cluster with mainly users from P1, who presented a simple use of pregabalin, and were older (> 45 years), were involved in opioid agonist treatment (OAT), and obtained pregabalin legally; and (ii) a cluster with mainly users from P2, who presented pregabalin dependence, and were younger (< 26 years), reported pregabalin as the first substance leading to dependence, used doses higher than the market authorization, were in severe precarity, and were in prison. CONCLUSIONS: These data showed that the profile of pregabalin users has changed in the last years. Pregabalin use disorders also affect users without history of addiction.

Patterns of ketamine use among people with substance use disorder in France: Multisource analysis of the data from the French Addictovigilance Network.

BACKGROUND: Due to its psychoactive effects, ketamine has become a drug used for non-medical purpose. OBJECTIVES: To assess the latest trends in ketamine use among people with substance use disorder and to characterize its clinical complications using complementary health data sources of the French Addictovigilance Network. METHODS: First, we extracted all reports involving ketamine from 2012 to 2021 from the database of the OPPIDUM program (i.e., a multicentric program conducted in collaboration with hundreds of substance abuse treatment facilities that collects data on drugs used by subjects with substance use disorders). We described the reports globally and the changes from 2012 to 2021. Second, we extracted all cases involving ketamine from July 2020 to December 2022 from the French National Pharmacovigilance Database (BNPV). We identified the cases related to ketamine use among people with substance use disorder and described them. RESULTS: There was a 2.5-fold increase in the number of ketamine users with substance use disorder in the OPPIDUM program, from 35 (0.7%) subjects in 2012 to 89 (1.7%) subjects in 2021. There was an increase in the proportion of subjects who were daily users, had distress upon discontinuation, and presented addiction. There were 238 cases related to ketamine use among people with substance use disorder in the French National Pharmacovigilance Database from July 2020 to December 2022. Among them, 94 (39.5%) cases involved ketamine use disorder, 20 (8.4%) cases involved urinary tract and kidney symptoms, and 13 (5.5%) cases involved hepatobiliary symptoms. CONCLUSION: The trend observed over 10 years reflects the growth in ketamine use among people with substance use disorder, although it does not allow to estimate the rates of non-medical use of ketamine in the general population. Ketamine-induced uropathy and cholangiopathy are reported in ketamine users with substance use disorder, especially in case of repeated and/or prolonged use of high doses.
