[Adequacy of hospital admissions and stays of patients with uncomplicated inguinal hernia]. / Adecuación de ingresos y estancias hospitalarias en pacientes con hernia inguinal sin complicaciones.

BACKGROUND: Inguinal hernia uncomplicated in patients aged over 17 years, diagnosis-related group (DRG) 162, generates a substantial number of hospital stays due its high frequency in our country. These stays may not be necessary, and present an important temporal and geographical variability. MATERIAL AND METHODS: We have analyzed a total of 612 days of stay belonging to the 124 admissions codified as DRG 162 during the first quarter of 1993 and 1994, using the "Appropriateness Evaluation Protocol". RESULTS: The overall mean stay of the DRG 162 was 5.0 days (2.3 days of inadequate stay and 2.7 days of clinically necessary stay). The mean stay in 1993, 5.6 days, was higher than the mean stay in 1994, 4.1 days (p = 0.006). The percentage of inappropriate admission was higher in 1993 than in 1994 (33.8% versus 18.9%; p = 0.06). Similarly, the percentage of inappropriate stay was higher in 1993 than in 1994 (46.9% versus 41.9%; p = 0.06). The more frequent reasons of inappropriate admission was premature admission (88.2%) and for the stay was delay in the discharge medical order (33.3%). CONCLUSIONS: The mean stay of DRG 162, as well as the percentage of inadequate stay and admission, has decreased from 1993 to 1994 in our hospital. According to the observed trend, the mean stay is approaching the adequate mean stay for this DRG.

[Relationship between coffee and blood cholesterol in a sample of working women]. / Relación entre el café y el colesterol plasmático en una población laboral femenina.

BACKGROUND: Experimental studies have demonstrated that unfiltered coffee increases cholesterolemia. In Spain, filtered coffee is mainly consumed and its effect on cholesterolemia is controversial. METHODS: The relationship between coffee intake and the serum levels of total cholesterol was transversally studied in a population of 609 women between 18 to 65 years in age. The questionnaire and analyses were carried out in the context of periodic health examination. RESULTS: The consumption of coffee was positively associated with cholesterolemia in subjects under 30 years of age (p < 0.01) and in the group from 30 to 45 years in age (p < 0.05). This association was found to be statistically significant on multivariant analysis (multiple lineal regression) after adjusting for age, body mass index, cholesterol consumed in the diet, smoking, alcohol consumption and physical activity. CONCLUSIONS: Coffee was found to increase cholesterolemia in the female population and therefore a reduction in coffee intake would be recommendable in hypercholesterolemic subjects.
