Objective: To compare the efficacy, safety, and tolerability of olanzapine and quetiapine in adolescents with first episode psychosis. Method: Fifty adolescents (age 16 ± 1.25) with a first episode of psychosis were randomized to quetiapine or olanzapine in a 6-month open label study. Efficacy and side effect scales, as well as vital signs and laboratory data were recorded at baseline, 7, 15, 30, 90, and 180 days (end of study). Results: Out of the total sample included in the study, 32 patients completed the trial (quetiapine n = 16, olanzapine n = 16). Patients in both treatment groups had a significant reduction in all clinical scales with the exception of the negative scale of the Positive and Negative Symptom Scale (PANSS) for olanzapine and the general psychopathology scale of the PANSS for quetiapine. The only difference between treatment arms on the clinical scales was observed on the patients' strength and difficulties questionnaire (SDQ) scale, with greater improvement for olanzapine. Patients on olanzapine gained 15.5 kg and patients on quetiapine gained 5.5 kg. Conclusion: Olanzapine and quetiapine reduced psychotic symptoms in this adolescent sample. Patients on olanzapine gained significantly more weight. Side effects with both drugs seemed to be more prevalent than those reported in adult studies

There has been a remarkable increase in prescription rates of antipsychotics in children and adolescents in recent years. Their side effects are a neglected area of research in this population, despite its vulnerability. In this cross-sectional study, we compared the presence of side effects in 60 children and adolescents who had taken antipsychotic medication for less than 1 month and 66 who had been receiving treatment with antipsychotics for more than 12 months. Mean age for the total sample was 15.62 years (SD 1.85). Groups did not differ in age, gender, or diagnosis. A total of 21.7% of short-term treatment group patients and 37.9% of longer-term treatment group patients presented mild dyskinetic movements (p = 0.004). Hyperprolactinemia was present in 78.6% and 48.5% in the short-term and longer-term treatment groups, respectively. Body mass index (p < 0.001), cholesterol levels (p < 0.001), and low-density lipoprotein-cholesterol (LDL-C) (p = 0.018) were higher in the longer-term treatment group. The use of these drugs in these populations merits careful scrutiny.

It is possible to implement the EFQM model at the hospital was level and it has a positive influence on staff communication and involvement. It is important, when working at this level, to adequately focus the scope of the project on improving quality in those areas where there is decision-making capacity.
