RESUMO
BACKGROUND: The elevated prevalence of osteoarthritis in Western countries, the high costs of hip and knee arthroplasty, and the wide variations in the clinical practice have generated considerable interest in comparing the associated costs before and after surgery. OBJECTIVE: To determine the influence of a number of variables on the costs of total knee and hip arthroplasty surgery during the hospital stay and during the one-year post-discharge. METHODS: A prospective multi-center study was performed in 15 hospitals from three Spanish regions. Relationships between the independent variables and the costs of hospital stay and postdischarge follow-up were analyzed by using multilevel models in which the "hospital" variable was used to group cases. Independent variables were: age, sex, body mass index, preoperative quality of life (SF-12, EQ-5 and Womac questionnaires), surgery (hip/knee), Charlson Index, general and local complications, number of beds and economic-institutional dependency of the hospital, the autonomous region to which it belongs, and the presence of a caregiver. RESULTS: The cost of hospital stay, excluding the cost of the prosthesis, was 4,734 Euros, and the post-discharge cost was 554 Euros. With regard to hospital stay costs, the variance among hospitals explained 44-46% of the total variance among the patients. With regard to the post-discharge costs, the variability among hospitals explained 7-9% of the variance among the patients. CONCLUSIONS: There is considerable potential for reducing the hospital stay costs of these patients, given that more than 44% of the observed variability was not determined by the clinical conditions of the patients but rather by the behavior of the hospitals.
antecedentes: la alta prevalencia de artrosis en los países occidentales, el elevado costo de las intervenciones de artroplastia de cadera y rodilla y las amplias variaciones en la práctica médica generan gran interés por comparar los costos asociados antes y después de la cirugía. Objetivo: conocer el costo de las intervenciones de reemplazo total de cadera y rodilla durante la estancia hospitalaria y al año de seguimiento posterior al alta. material y métodos: estudio multicéntrico y prospectivo efectuado en 15 hospitales de tres comunidades autónomas. La relación entre las variables independientes con el costo de la estancia y costo post-alta, se analizó con modelos multinivel y para agrupar los casos se utilizó la variable "hospital." Las variables independientes fueron: edad, sexo, índice de masa corporal, calidad de vida prequirúrgica (cuestionarios ED-5D, SF-12 y Womac), intervención (cadera-rodilla), índice Charlson, complicaciones, número de camas y dependencia económico-institucional del hospital, comunidad autó-noma y presencia de cuidador. Resultados: el costo promedio por paciente, sin incluir el costo de la prótesis, fue de 4,734 Euros ± 2,136 y el costo del seguimiento post alta de 554 Euros ± 509. Si se incluye el costo de la prótesis, al final del año el costo total asciende a 7,645 Euros ± 2,248. Conclusiones: existe un margen considerable en la reducción de los costos de estancia; más de 44% de la variabilidad observada no está determinada por las condiciones clínicas de los pacientes sino por el comportamiento de los centros hospitalarios.

BACKGROUND: The current trend in patient care is towards a more humanized and higher-quality healthcare. The objective of the present study was to evaluate the results of implementing a programme of healthcare with a reference nurse who welcomes the patient at hospital admission, visits regularly during hospital stay, and resolves doubts and problems. METHODS: Quasi-experimental study (149 cases and 454 non-tutored controls) in patients admitted for scheduled trauma surgery at the Virgen de las Nieves University Hospital, Granada. Sociodemographic and clinical data were gathered at admission. At 15 days after discharge, patients were administered with an interviewer-administered Zung score and an ad hoc questionnaire on satisfaction with different healthcare aspects during hospital stay and understanding of information received. Bivariate analyses and linear and multivariate logistic regression analyses were performed with a study of confounding variables. RESULTS: For the outcome variable anxiety level non-tutored patients had a B coefficient of 2.64 (p<0,01) in the multivariate linear regression analysis controlling for the other variables in the final model: sex, presence of informal career, professional activity, days of hospital stay and understanding of health information. For the outcome variable inadequate understanding information non-tutored patients showed an odds ratio of 3.48 in the multivariate analysis controlling for educational level and presence of informal career. Satisfaction with he friendliness of health care personnel and with the hospital setting did not significantly difference, although the percentage of dissatisfied patients was higher in the non-tutored group: 15% vs 11% (p= 0.34) and 18% vs 12 % (p= 0.11) respectively. CONCLUSIONS: The implemented continued care programme proved effective for these patients, increasing their understanding of information received and reducing anxiety levels.
