Individualized pretest risk estimates to guide treatment decisions in patients with clinical high risk for psychotic disorders.

INTRODUCTION: Clinical High Risk for Psychosis (CHR) states are associated with an increased risk of transition to psychosis. However, the predictive value of CHR screening interviews is dependent on pretest risk enrichment in referred patients. This poses a major obstacle to CHR outreach campaigns since they invariably lead to risk dilution through enhanced awareness. A potential compensatory strategy is to use estimates of individual pretest risk as a 'gatekeeper' for specialized assessment. We aimed to test a risk stratification model previously developed in London, UK (OASIS) and to train a new predictive model for the Swiss population. METHOD: The sample was composed of 513 individuals referred for CHR assessment from six Swiss early psychosis detection services. Sociodemographic variables available at referral were used as predictors whereas the outcome variable was transition to psychosis. RESULTS: Replication of the risk stratification model developed in OASIS resulted in poor performance (Harrel's c = 0.51). Retraining resulted in moderate discrimination (Harrel's c = 0.67) which significantly differentiated between different risk groups. The lowest risk group had a cumulative transition incidence of 6.4% (CI: 0% - 23.1%) over two years. CONCLUSION: Failure to replicate the OASIS risk stratification model might reflect differences in the public health care systems and referral structures between Switzerland and London. Retraining resulted in a model with adequate discrimination performance. The developed model in combination with CHR assessment result, might be useful for identifying individuals with high pretest risk, who might benefit most from specialized intervention.

Pathways to care in youth and young adults at clinical high risk for psychosis in Switzerland: Current situation and clinical implementation of the PsyYoung project.

AIM: We aim to give an insight into the current situation in Switzerland concerning the pathways to care of young people with clinical high risk of psychosis. In a second step we propose a procedure of optimizing pathways to care developed within the project PsyYoung. METHODS: A qualitative survey derived and adapted from Kotlicka-Antczak et al. (2020) was conducted in large early detection services of three Swiss cantons (Geneva, Basel-Stadt, Vaud) focusing on pathways to care. More specifically, using questionnaires delivered to the heads of participating services, information was collected on referral sources, on activities to implement outreach campaigns and on the use of a pre-screening tool. RESULTS: Main results on referral source indicated that sources were variable but seemed to come primarily from the medical sector and more so from the psychiatric sector. Very few referrals came from non-medical sectors. Outreach activities included the contact to other clinics as well as through brochures and posters. All services but one used the Prodromal Questionnaire - 16 as pre-screening tool. CONCLUSIONS: All in all, the results indicate a referral and care pathway system implemented mostly within the medical and particularly mental health sector. Accordingly, the PsyYoung project proposes a procedure for pathways to care which could help overcome the obstacle of referrals being restrained to a narrow field of mental health and to harmonize the referral process within services dedicated to the same aim of helping young people at high risk of developing a psychosis.

Comparison of Tympanostomy Tubes Under Local Anesthesia Versus General Anesthesia for Children.

OBJECTIVE: Tympanostomy tube insertion (TTI) is typically accomplished under general anesthesia (GA) in the operating room. We aimed to compare pain between GA and local anesthesia (LA) in surgically naïve children undergoing TTI. Secondary objectives examined patient's quality of life (QoL) and parent's satisfaction. STUDY DESIGN: Prospective single-center study. SETTING: Tertiary pediatric academic center. METHODS: Consecutive children who underwent TTI under GA were compared to patients under LA. Pain standardized observational pain scales (Face, Legs, Activity, Cry, Consolability Scale [FLACC], Children's hospital of Eastern Ontario Pain Scale [CHEOPS]) were completed pre-procedure, during the first tympanostomy and second tympanostomy, and post-procedure, as well as 1 week postoperatively. General health-related QoL (PedsQL) and QoL specific to otitis media (OM-6) were measured before insertion and 1 month postoperatively. Parental satisfaction was also evaluated using a qualitative scale. RESULTS: LA group had statistically significant higher pain levels at the beginning (7.3 vs. 0), during the first tympanostomy (7.8 vs. 0), during the second tympanostomy (7.7 vs. 0), and at end of the procedure (6.9 vs. 0) with the FLACC scale (all p < 0.01). Results were similar with the CHEOPS scale. No pain was noted 1 week after surgery in either group. Both groups had similar improvement in their QoL (p > 0.05). Minor complication occurred at a similar rate (p > 0.05). Parents were equally satisfied with their choice of anesthesia in both groups when initially questioned after the procedure (p > 0.05). CONCLUSIONS: Children experienced significantly less pain under GA than LA. If LA is to be used, pain and distress-reducing strategies are critical. Shared decision-making with families is essential.

Improving Pathways to Care for Patients at High Psychosis Risk in Switzerland: PsyYoung Study Protocol.

AIMS: Psychotic disorders are one of the main causes of chronic disability in young people. An at-risk mental state (ARMS) is represented by subclinical symptoms that precede the first episode of psychosis (FEP). The PsyYoung project aims to optimize the detection of an ARMS while reducing unnecessary psychiatric treatments. It investigates the effects of service changes on the referrals and outcomes of young people with ARMS or a FEP. METHODS: Six psychiatric outpatient clinics in three cantons (Basel-Stadt, Vaud, and Geneva) participated in the project. They passed through an implementation phase including service changes and the adaptation of a standardized stepped care model for diagnosis and assessment, in addition to measures for increasing the awareness, networking and training of local professionals. PRELIMINARY RESULTS: All participating cantons had entered the implementation phase. By March 2023, there were 619 referrals to participating sites. A total of 163 patients (37% FEP and 31% ARMS) and 15 close relatives had participated in individual longitudinal assessments, and 26 patients participated in qualitative interviews. CONCLUSION: This national collaborative project addresses the issue of early intervention for emerging psychoses, and creates spaces for fruitful reflections and collaboration in Switzerland. The ultimate aim of PsyYoung is to harmonize clinical practices in early intervention of psychosis on a national level.
