DELGADO MORALES, J. L. et al. Observational study of in-patients in an Internal Medicine Department. []. , 21, 1, pp.3-6. ISSN 0212-7199.

Objectives: To analyse the entered more frequent diseases in an Internal Medicine Department , the reasons for hospital admission diagnosis at discharge (according to entrance symptom’s guide), the group of affected population and its correlation among them. Patients and methods: Over a total of 758 internal medicine admissions of the University Hospital of Valladolid during the year 1999 based on the information of discharge and clinical histories, a descriptive and observational epidemic study was made using the variables of sex, age, reason for admission (guide symptom ) and diagnosis at discharge. The obtained results were represented by mean of diagrams of sectors and bars according to the analyzed variables. The data synthesis was made by measures of central tendency and dispersion. SPSS 10.0 version for windows program was used for the statistical study. The non parametric analysis for independent samples was made by the test of median and the U of Mann Whitney, and the parametric by chi-squired test and resistance of Kolmogorov-Smirnov. Results: The median of age is 70 years. Rank 84 years. Interquartile rank 23, fashion in men 75 years and in women 86. The distribution in sex men 51%, women 49%.The more frequent reasons for entrance are dyspnea (35%) and neurological focus (11%).The more frequent diagnosis at discharge are dyspnea and chronic obstructive lung disease worsened by respiratory infection (11%), pneumonia (8%) and acute isquemic stroke (7%). Conclusions: In-patiens in this service, are advanced in years (mainly women) (α = 0.05). The age does not get a normal distribution  (α = 0.05). The frequency of the distribution in sex is similar. The most frequent reason for admission is dyspnea (35%). The most frequent diagnoses at discharge are chronic obstructive lung disease (11%), pneumonia (8%) and acute ischemic stroke (7%). The primary and secondary prevention and an improvement of the therapeutic measures of chronic cardiopulmonary disease would reduce significantly the welfare pressure in Internal Medicine Departement and they would improve the population’s life quality given that we are opposed to the diseases which are among the four first mortality causes in the world.
