نبذة مختصرة : Introduction Limited information is available regarding the clinical features, optimal treatment and prognosis of Paranoid Personality Disorder (PPD) and Delusional Disorder (DD). This is partly due to the low prevalence of cases and poor patient insight. The difference between DD and PPD has been questioned in the literature, as some studies have described them as a continuum, highlighting the role of specific personality traits in the transition to clinical delusions. Nonadherence to pharmacological treatment is one of the most challenging aspects. This further leads to relapses, increased use of emergency psychiatric services, psychiatric admissions, longer periods of hospitalization, and an increased cost of illness to healthcare systems. Objectives The primary goal of this study is to compare the differences between DD and PPD in terms of medication adherence, relapses, lost to follow-up, and costs. Other aims of this study are to analyze the differences in these variables between patients who are adequately adherent and patients who are not Methods An observational, retrospective, and multicenter descriptive epidemiological study was conducted. Patients were selected from four public departments of psychiatry in Madrid, providing an area of roughly one million people. All patients were older than 18 years-old, diagnosed with DD or PPD from 2005 to 2022. Data were extracted from electronic medical records and from electronic prescribing program used in the public health system.The study was approved by the Hospital Fundación Jiménez Díaz Ethics Committee. Results 1227 individuals diagnosed with DD (974 patients,79,3%) or PPD (253 patients, 20.61%). 23.81% (232 patients) of the DD-group did not take out the prescribed medication of the pharmacy, and 16.6% (42 patients) of the PPD-group were considered non-adherent. Adherent patients had greater follow-up (4.02 vs 2.89 years) and shorter hospital stays (5.15 vs 8.6 days, p
