Índice de severidad del área de psoriasis (PASI) en pacientes del Hospital Nacional Daniel Alcides Carrión durante el período 1996-2005 / Psoriasis area and severity index (PASI) in patients of the National Hospital Daniel Alcides Carrion during the period of 1996 to 2005

OBJETIVO: Evaluar el índice de severidad del área de psoriasis (PASI) en 349 pacientes nuevos que ingresaron al programa de Psoriasis del Hospital Nacional Daniel Alcides Carrión (HNDAC) en el período 1996-2005. MATERIAL Y MÉTODOS: Estudio descriptivo, retrospectivo y observacional. Se recolectó los informes de las evaluaciones del PASI realizadas en la primera consulta del paciente psoriásico que ingresaba al programa y se correlacionó con la edad, sexo y tiempo de enfermedad. Se realizó estadística univariada y bivariada con las pruebas estadísticas del Chi Cuadrado y U de Mann Whitney con un nivel de confianza del 95 por ciento. RESULTADOS: La edad promedio de los pacientes fue de 42.6 años, con predominio de psoriasis tipo II. Se obtuvo un promedio general de PASI de 12.3 (Psoriasis leve). En los varones el PASI promedio fue de 15.04 y en las mujeres de 9.37 (p menor que 0.0001). El tiempo de enfermedad promedio fue de 9.6 años, existió diferencia estadísticamente significativa para el tiempo de enfermedad en pacientes PASI severo en comparación con aquellos que tenían PASI leve y moderado. CONCLUSIÓN: En el HNDAC la psoriasis severa muestra mayor severidad en varones con un tiempo de enfermedad mayor.

AIM: To evaluate the psoriasis area and severity index (PASI) in 349 new patients admitted to the Psoriasis Program of the National Hospital Daniel Alcides Carrion (HNAC) since 1996 to 2005. MATERIAL AND METHODS: Descriptive, retrospective and observational study. The reports of the evaluations made of Psoriasis Area and Severity Index, (PASI) in patients of the Hospital Daniel Alcides Carrion that income by the first time to the program and were correlated with the age, sex and time of illness. It has been revised with the statistical test of the Chi square and Mann Whitney (comparation of averages). RESULTS: The average age was 42,6, with prevalent of psoriaris type II. The average of PASI was 12.3 (mild psoriasis); for males the average arose to 15.04 and for women 9.37; with a significant statistical difference of p = 0001 It was 42.6 years old average, talking about the age in which prevails the psoriasis type II. The average last of illness was 9.6 years. There was a significant statistical difference for time of illness in severe PASI patients in comparison with these with mild or moderated PASI. CONCLUSION: At the HNDAC, severe psoriasis showed major severity in males with a major time of sickness.

A practical approach to advanced terminology services in health information systems.

As the medical informatics field evolves, new functions appear as the focus of interest; a more advanced management of terminology is one of them. Using comprehensive and detailed terminology to represent clinical rules in computer systems, associated with patient information, would allow clinical software to provide patient specific recommendations or alerts. In order to uniform data collection through our HIS, and lay the foundations for future clinical decision support systems, we decided to move from our previous classification-based medical record into new terminology services built around Snomed CT, Spanish Language Version. This paper describes the characteristics of our Terminology Server. The most important achievements of our new terminology system are the centralization of knowledge representation, using a much more detailed terminology system. Clinical data entered at any place of the institution and level of care, is represented uniformly through the whole health information system.

Creation of a local interface terminology to SNOMED CT.

This paper describes the steps followed in the creation of a local Interface Terminology to SNOMED CT (as reference terminology) with a strong focus on user acceptability. The resulting list of terms is used for clinical data input by physicians and nurses at the Hospital Italiano in Buenos Aires, Argentina. Description includes data model, mappings to SNOMED CT and classifications, subsets definitions and extensibility mechanisms. The Interface Terminology is currently used in the recording of diagnosis and procedures in inpatient discharge summaries and its coverage is improving from user feedback. Its current size is 24,800 concepts, 67% of them needed post-coordination for appropriate semantic representation, due to a very flexible policy that allows the use of any number of modifiers on concepts.
