OBJECTIVES To estimate models, via ordinary least squares regression, for predicting Euro Qol 5D (EQ-5D), Short Form 6D (SF-6D), and 15D utilities from scale scores of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). METHODS Forty-eight gastric cancer patients, split up into equal subgroups by(More)
OBJECTIVES The main purpose of this study was to assess the construct validity of the Greek EQ-5D instrument in measuring health-related quality of life, as well as to address the issues of concurrent validity, internal consistency reliability, and sensitivity. METHODS A stratified, representative sample (n = 1388) of the Greek general population was(More)
BACKGROUND Diabetes Mellitus (DM) is a major cause of morbidity and mortality affecting millions of people worldwide, while placing a noteworthy strain on public health funding. The aim of this study was to assess health-related quality of life (HRQOL) of Greek Type II DM patients and to identify significant predictors of the disease in this patient(More)
BACKGROUND The 12-item Health Survey (SF-12) was developed as a shorter alternative to the SF-36 for use in large-scale studies, particularly when overall physical and mental health are the outcomes of interest instead of the typical eight-scale profile. The main purpose of this study was to assess the validity of the Greek version of the SF-12. METHODS A(More)
OBJECTIVES The Greek National Health System has been subjected to a reform initiative in 2001. The new legislation required hospitals to operate as administrative and economic decentralized units, under the control of newly established Regional Health Systems. In addition, Professional Managers have been appointed and signed "efficiency contracts", which(More)
OBJECTIVES To compare the EQ-5D and SF-6D within socio-demographic and clinical groups in a representative sample (n = 1,005) of the Greek general population and to examine mean utility differences across groups differing in health in this population and in a highly morbid disease sample (diabetes, n = 215). METHODS Association and level of agreement(More)
OBJECTIVES The purpose of this methodological study was to to provide insight into the under-addressed issue of the longitudinal predictive ability of mapping models. Post-intervention predicted and reported utilities were compared, and the effect of disease severity on the observed differences was examined. METHODS A cohort of 120 rheumatoid arthritis(More)
OBJECTIVES To estimate lifelong costs and quality adjusted life years (QALYs) of hemodialysis (HD), peritoneal dialysis (PD) and renal transplantation (Tx) in Greece, based on individual patient life expectancy. METHODS A nationally representative patient sample on each modality, HD: N=642, PD: N=65 and Tx: N=167, was self-administered the SF-36 Health(More)
To increase Data Envelopment Analysis (DEA) discrimination of efficient Decision Making Units (DMUs), by complementing "self-evaluated" efficiencies with "peer-evaluated" cross-efficiencies and, based on these results, to classify the DMUs using cluster analysis. Healthcare, which is deprived of such studies, was chosen as the study area. The sample(More)
