Modeling cross-border care in the EU using a principal-agent framework.
Cross-border care is likely to become a major issue among EU countries because patients have the option of obtaining treatment abroad under Community Regulations 1408/71. This paper develops a model formalizing both the patient's decision to apply for cross-border care and the authorizing physician's decision to admit a patient to the program. The patient is assumed to maximize expected utility, which depends on the quality of care and the length of waiting in the home country and the host country, respectively. Not all patients qualifying for the EU program present themselves to the authorizing physician because of the transaction cost involved. The physician in her turn shapes effective demand for authorization through her rate of refusal, which constitutes information to potential applicants about the probability of obtaining treatment abroad. The authorizing physician thus acts as an agent serving two principals, her patient and her national government, trading off the perceived utility loss of patients who are rejected against her commitment to domestic health policy. The model may be used to explain existing patient flows between EU countries.

[Validity of the Spanish version of the Addenbrooke's Cognitive Examination for the diagnosis of dementia and to differentiate Alzheimer's disease and frontotemporal dementia].
INTRODUCTION: The Addenbrooke's Cognitive Examination (ACE) is a brief bedside test battery to detect mild dementia and differentiate frontotemporal dementia (FTD) from Alzheimer's disease (AD). AIM: To validate the ACE in Spanish. PATIENTS AND METHODS: The study evaluated the Spanish version of ACE on 128 subjects consisting in two groups a patient group (n = 76) and a control subjects group (n = 52). The patient group was divided in AD (n = 54) based on the NINCDS-ADRDA criteria and FTD (n = 22) based on the Lund y Manchester criteria. All patients underwent clinical, neuropsychological, radiologic (MRI, CT, and SPECT), and laboratory evaluations. Group's differences were evaluated using ANOVA. The internal consistency of the Spanish version of the ACE was measured using the Cronbach's alpha coefficient. The discriminative capability of the Spanish version of the ACE was examined by the receiver operating characteristic (ROC) analysis. RESULTS: The cut-off score of 86 showed a sensitivity of 92% (CI 95% = 83.6-97.0) and a specificity of 96.2% (CI 95% = 86.8-99.4). The ROC curve showed higher sensitivity and specificity of the ACE than the Mini-Mental State Examination in discriminating the dementia and control group. The VLOM ratio (verbal fluency + language)/(orientation + memory) of < 1.82 discriminated for FTD and > 4.87 discriminated for AD. CONCLUSION: The Spanish version of ACE is a brief and reliable instrument for early detection of dementia in highly educated people and offers a simple objective index to differentiate AD and FTD. More studies in less educated people are warranted.
