    ABSTRACT: Objetivo. Evaluar la relación coste-efectividad del tratamiento en procesos complejos predefinidos que precisan ventilación mecánica (VM). Diseño. Estudio de cohorte retrospectivo con análisis coste-efectividad y estimación del porcentaje de pacientes sometidos a cuidados potencialmente ineficientes (CPI). Ámbito. Unidad de Cuidados Intensivos (UCI) de un hospital general. Pacientes. Pacientes ingresados entre los años 1997 y 2001, asignados al alta hospitalaria a los GRD 475 (diagnósticos del sistema respiratorio con ventilación asistida) y 483 (traqueostomía excepto trastornos de la boca, laringe o faringe). Intervenciones. Ninguna. Variables de interés principales. Edad, sexo, gravedad (mediante APACHE II), estado crónico de salud, grupo patológico de base, estancia en UCI, estancia hospitalaria, duración de la VM, mortalidad hospitalaria predicha y observada. Estimación del coste-efectividad mediante cociente entre costes totales hospitalarios y años de vida ganados (avg). Porcentaje de pacientes sometidos a CPI, definido como pacientes con costes totales superiores al percentil 90 y destino exitus. Resultados. Se estudiaron 247 pacientes, 142 del GRD 475 y 105 del GRD 483. Los dos grupos poseían características similares, salvo mayor predominio de pacientes médicos, menor estancia y duración de VM en el GRD 475. El coste-efectividad fue favorable en todos los subgrupos estudiados, y mostró un incremento en ambos grupos de GRD según aumentaba la edad, la gravedad y la duración de la VM. La distribución del coste-efectividad por estado crónico de salud no mostró diferencias en el GRD 475, mientras que en el GRD 483 se producía un incremento del mismo según empeoraba el estado de salud. En el GRD 483 y grupo patológico de base cardiológico, se observaron los peores valores de coste-efectividad. El porcentaje de CPI fue del 7,0% en GRD 475 y del 5,4% en GRD 483. Conclusiones. El tratamiento de los pacientes críticos agrupables a los GRD 475 y 483, se ha mostrado coste-efectivo de forma global y en todos los subgrupos analizados. La estimación del coste-efectividad y del porcentaje de pacientes sometidos a CPI, en procesos con similar complejidad de la casuística, ofrece información médica y económica del funcionamiento de una UCI.

    ABSTRACT: El absceso prostático es una enfermedad poco frecuente, asociada generalmente a prostatitis, y cuyo diagnóstico puede retrasarse por lo inespecífico de la clínica. Es aún más raro que aparezcan complicaciones graves sistémicas. Será preciso un alto nivel de sospecha y la realización de técnicas de imagen para llegar a un diagnóstico de certeza. Presentamos el caso de un paciente en situación de shock séptico secundario a un absceso de próstata. Tras revisar la bibliografía comprobamos que son escasos los casos documentados de complicaciones sistémicas graves de este tipo de pacientes.

    ABSTRACT: Scarce information is available about the use, clinical course and follow-up of patients with acute myocardial infarction treated with mechanical ventilation. Historical cohort study of patients with acute myocardial infarction, included in Spanish registry ARIAM. Differences in clinical characteristics and prognosis from patients treated with or without mechanical ventilation were compared. Three hundred and thirty-three of the 4143 patients (8.1%) with acute myocardial infarction were treated with mechanical ventilation. Treated patients were older, more frequently female, and had more frequently reinfarcts, anterior infarction, Killip III and IV, and higher creatine phosphokinase peak. Diabetes and high blood pressure were more frequent in those in which the technique was applied. They had a higher mortality at the coronary care unit (65.7 vs 5.1%; p < 0.001) than the non-ventilated patients. In multivariate analysis, creatine phosphokinase peak levels higher than 1.200 units/ml, Killip III and IV, and an infarction localization different to inferior were independent predictors of mechanical ventilation application. The 220 treated patients who died were older, more frequently female, had been more frequently admitted to the coronary unit, and had Killip IV whereas Killip III was more frequent among survivors. In multivariate analysis, restricted to patients treated with mechanical ventilation, Killip III was an independent predictor of survival with an odds ratio for mortality of 0.26 (CI 95%: 0.09-0.77). CONCUSIONS: Mechanical ventilation is a vital support technique employed in a significant number of complicated acute myocardial infarction patients. The high mortality of these patients was related to more extended myocardial infarction and a worse clinical state.

    ABSTRACT: Introduction The clinical-financial management of an intensive care unit (ICU) necessitates a method to approximate individual costs and establish a costs proxy. The aim of this study was to analyze actual costs and their estimation through severity and activity scores, as well as to evaluate whether at an individual level the nine equivalents of nursing manpower use score (NEMS) could be useful for their measurement. Method We performed a cohort study of patients admitted to an ICU in 2000. Stratified random sampling was used to select 106 patients with the 14 most common diagnosis-related groups (DRG). Direct variable costs for each patient were registered with allocation of direct and indirect fixed costs according to length of hospital stay. Length of hospital stay, physiological severity of illness indices (APACHE II, SAPS II, MPM 0, MPM 24) and therapeutic dependence scales (NEMS, TISS-28 and OMEGA) were measured. Statistical analysis was based on Spearman’s correlation coefficient between total costs and indexes. The actual and theoretical costs calculated on the basis of the NEMS were compared by the median difference between these costs (AMD, 5th and 95th percentile) and by the Bland and Altman analysis. The values are expressed as means (95% confidence interval). Results One hundred and six patients were selected from 861 patients in whom length of hospital stay was 1 day or more. The mean age was 68.2 years (65.4; 71.0); 74 were men; length of hospital stay: 7.3 (5.3; 9.3); mean APACHE II score: 17.6 (16.0; 19.2); NEMS: 219.7 (153.7; 285.8); DRG weight: 5.8 (4.6; 6.9); cost/patient 6767.34 euros (4919.95; 8614.74); costs per DRG/patient: 6282.29 euros (4992.82; 7571.76); cost/NEMS: 12.42 euros (11.09; 13.76); cost/length of hospital stay ratio: 921.28 euros (888.22; 954.34). The results of Spearman’s correlation coefficient were as follows, r (p): Length of hospital stay: 0.98 (0.000); APACHE II 0.36 (0.000); SAPS II 0.27 (0.007); MPM 0 0.20 (0.032); MPM 24 0.21 (0.029); NEMS 0.92 (0.000); TISS-28 0.91 (0.000); OMEGA 0.85 (0.000); DRG weight 0.55 (0.000). AMD: –154.71 (–3719.86/958.07). Conclusions Cost calculation through the method described was more approximate than allocation by DRG. The component with the greatest impact on total costs was length of hospital stay. NEMS may be useful for calculating actual costs. Even when there are individual differences between actual and estimated costs, the method used can be useful to calculate the financial resources of an ICU.
