Objetivos: Evaluar la eficacia de un programa de intercambio de jeringuillas (PIJ) en una prisión para reducir la prevalencia de infecciones asociadas al uso de drogas intravenosas, y conocer la aceptación del programa por internos y funcionarios del centro penitenciario. Material y métodos: Estudio observacional con cortes transversales al inicio, 6 y 12 meses y 10 años de desarrollo del programa. Se realizaron entrevistas a los usuarios del programa y encuestas a muestras accidentales de funcionarios en los distintos cortes, y a una muestra aleatoria de internos a los 10 años. Se registraron diariamente los indicadores de actividad del programa, y se valoró la prevalencia de infección por VIH, hepatitis B y C al inicio y a los 10 años. Para el análisis estadístico utilizamos la prueba ji-cuadrado con la corrección de Yates en caso necesario. Resultados: Durante estos diez años se suministraron 15.962 jeringuillas a 429 usuarios (media de 20,2 usuarios/mes), recuperándose 11.327 (70,9%). La prevalencia de infección por VIH pasó del 21% en 1999 al 8,5% en 2009, la de VHC del 40% al 26,1% (pObjectives: To evaluate the effectiveness of NEPs in prison to reduce the prevalence of infections associated with intravenous drug use and to know more about acceptance of the program by inmates and staff. Material and methods: cross-sectional observational study at baseline, 6 and 12 months and 10 years of program development. Interviews were conducted with program users, as well as random sample surveys of officials at the various cuts, and a random sample of inmates from the centre after10 years. Activity indicators of the program were recorded continuously, and the prevalence of HIV, HBV and HCV at baseline and after 10 years was evaluated. For the statistical analysis, the chi-square test was used with the Yates correction when necessary. Results: In ten years we have supplied a total of 15,962 syringes to 429 users, (average 20.2 users/month), and 11,327 (70.9%) were returned. The prevalence of HIV infection decreased from 21% in 1999 to 8.5% in 2009, HCV prevalence from 40% to 26.1% (p

Abstract Aims Disturbances in personality and addictions are associated with an increased risk of committing crimes and therefore of being imprisoned. In this study, the relationship between these factors is analyzed through a sample of inmates in the Prison of Pereiro de Aguiar, Ourense. Material and method 204 inmates participated in this transversal simple blind design study. The following variables were analyzed: presence of personality disorders and psychopathy, history of addictive psychoactive substance use, criminal history and socio-demographic variables. Results 101 (49.5%) inmates received a diagnosis of personality disorder, the most frequent being: narcissistic, 43 (21.08%); antisocial, 38 (18.63%); and paranoid, 29 (14.22%). The presence of any personality disorder was associated with an increase in the risk of committing crimes, especially violence and crimes against property. The most frequent personality disorders were associated with higher scores in the psychopathy assessment tools. Higher scores in the Psychopathy Checklist Reviewed (PCL-R) correlated with an increased risk of committing the following crimes: violent, against public health, against property and disorderly conduct. The consumption of addictive psychoactive substances was associated with the commission of crimes against property. Methadone stood out for its protective role against the commission of violent crimes. Discussion This sample shows that inmates have a higher prevalence of personality disorders, psychopathy and consumption of addictive psychoactive substances. These three variables significantly increased the risk of committing crimes.

Interviews were conducted with program users, as well as random sample surveys of officials at the various cuts, and a random sample of inmates from the centre after10 years.

The prevalence of HIV infection decreased from 21% in 1999 to 8.5% in 2009, HCV prevalence from 40% to 26.1% (p <0.01), finding no significant differences in the prevalence of HBsAg +. Most of the inmates and civil servants believe that the program did not increase intravenous drug use and improves hygienic living conditions in prison., Conclusions: After ten years of development of the NEP, there was a significant decrease in the prevalence of HIV and HCV in the prison population at the centre, and the program is accepted as beneficial by most of the inmates and staff participating in the survey.
