[Suitability of the use of low-molecular-weight heparins in the prevention of venous thromboembolism]. / Adecuación de la utilización de heparinas de bajo peso molecular en la prevención de la enfermedad tromboembólica venosa.

OBJECTIVE: To investigate the prevalence of low-molecular-weight heparin (LMWH) prescription in venous thromboembolism prophylaxis in a general hospital and the suitability of the recommendations from the clinical practice guidelines. METHOD: A descriptive, observational and cross-sectional study of the indication-prescription type, carried out on patients admitted to medical departments and for surgery. RESULTS: 345 patients were included. The prevalence of HBPM use was 44.6% (95% CI, 39.3-50.1). Depending on the risk of thromboembolism, the decision to treat prophylactically (or not) was appropriate in 261 cases (75.7%; 95% CI, 70.7-80.1), and the action guidelines were not suitable for the remainder of patients. 55 patients (15.9%; 95% CI, 12.2-20.2) presented a high risk and were not prescribed prophylactically (underuse); and 29 patients (8.4%; 95% CI, 5.7-11.8) at low risk were treated prophylactically (overuse). There was a relationship between the appropriateness of the prescription and the type of patient (p<0.01). In the group of medical patients the prevalence of prescription was 22.6% (95% CI, 16.9-29.1) and only 33.3% of patients with a high to moderate risk of thromboembolism received prophylaxis. The prevalence of prescription in general surgery was 84.2% and 91.3% in traumatology. CONCLUSIONS: The degree of prophylaxis is adequate in surgical patients, but there was a significant percentage of medical patients with a high to moderate risk who did not receive suitable prophylaxis (underuse), despite recommendations with scientific and professional backing.

[Prevalence of obesity in hospitalized internal medicine patients]. / Prevalencia de obesidad en pacientes médicos hospitalizados.

OBJECTIVE: We describe the weight's distribution in a sample of medical patients in hospital. We estimate the global prevalence and the presence between other different clinical variables. MATERIAL AND METHODS: A prevalence cross-sectional study was carried out. We determine weight, stature and several clinical variables in 101 patients admit in the internal medicine department of Juan Ramón Jiménez hospital in Huelva. The patients were admitted from 6th to 7th of june in 2000. The Body Mass Index (BMI) > or = 30 Kg/m2 was used to define the obesity. RESULTS: The prevalence of obesity was 32.2% [0.236-0.416]. In the study we find an association with female (prevalente rate -PR- 3.22), HTA (PR 4.72), dislipemia (RP 4.40) and hyperuricacemia (RP 4.28). CONCLUSIONS: The prevalence of obesity in our patients was between 23.41%, it was greater than others estimations in general people. We find association with women and classic cardiovascular risk factors.

Prevalencia de obesidad en pacientes médicos hospitalizados / Prevalence of obesity in an internal medicine department

Fundamento: Se describe la distribución ponderal de una muestra de pacientes médicos hospitalizados. Se estima la prevalencia global y su presencia entre diferentes variables clínicas. Material y métodos: Se diseñó un estudio descriptivo de prevalencia y se determinó el peso, la talla y diversas variables clínicas de 101 pacientes hospitalizados en el Servicio de Medicina Interna del Hospital Juan Ramón Jiménez de Huelva. Los pacientes fueron ingresados entre los días 6-7 de junio de 2000. La obesidad fue definida por un índice de masa corporal (IMC) 30 Kg/m2. Resultados: La prevalencia de la obesidad global fue de 32,7% [0,236 - 0,416]. En el estudio encontramos asociación estadísticamente significativa con el sexo femenino (Razón de prevalencia -RP- 3,22), HTA (RP 4,72), dislipemia (RP 4,40) e hiperuricemia (RP4,28). Conclusiones: La prevalencia de obesidad de nuestros pacientes oscila entre el 23 y 41%, por encima de las estimaciones sobre población general. Más prevalente entre las mujeres y asociada a los factores de riesgo cardiovasculares clásicos (AU)
