Assessment of a remote monitoring system for implantable cardioverter defibrillators.

We conducted a multicentre study in five Italian hospitals to assess the feasibility of a remote monitoring service for the follow-up of implanted cardiac devices. The system was designed to monitor device performance as well as physiological aspects of the patient's condition. Sixty-seven patients (mean age 64 years) affected by chronic heart failure and with a biventricular implantable cardioverter defibrillator for cardiac re-synchronization therapy (CRT-D) were enrolled for a three-month observation period. A total of 267 device recordings were transmitted through the ordinary telephone network, with a success rate of 99%. The telemonitoring service was more efficient than conventional face-to-face follow-up in terms of the time savings: both for physicians (4.7 minutes versus 15 minutes for remote and conventional monitoring) and for patients (6.6 minutes versus 116.3 minutes). In addition, a total of 23 clinical events occurred during the study, but only two cases required a clinic visit, thus reducing inappropriate hospital admissions. Finally, the service was well accepted by all the users.

Economic appraisal of the angioplasty procedures performed in 2004 in a high-volume diagnostic and interventional cardiology unit.

OBJECTIVE: Growing interest in the use of drug-eluting stents (DESs) in coronary angioplasty has prompted the Healthcare Agency of the Emilia Romagna Region to draw up recommendations for their appropriate clinical use in high-risk patients. Since the adoption of any new technology necessitates economic appraisal, we analysed the resource consumption of the various types of angioplasty procedures and the impact on the budget of a cardiology department. METHODS: A retrospective economic appraisal was carried out on the coronary angioplasty procedures performed in 2004 in the Department of Interventional Cardiology of Reggio Emilia. On the basis of the principles of activity-based costing, detailed hospital costs were estimated for each procedure and compared with the relevant diagnosis-related group (DRG) reimbursement. RESULTS: In 2004, the Reggio Emilia hospital performed 806 angioplasty procedures for a total expenditure of euro 5,176,268. These were 93 plain old balloon angioplasty procedures (euro 487,329), 401 procedures with bare-metal stents (euro 2,380,071), 249 procedures with DESs (euro 1,827,386) and 63 mixed procedures (euro 481,480). Reimbursements amounted to euro 5,816,748 (11% from plain old balloon angioplasty, 50% from bare-metal stent, 31% from DES and 8% from mixed procedures) with a positive margin of about euro 680,480 between costs incurred and reimbursements obtained, even if the reimbursement for DES and mixed procedures was not covering all the incurred costs. CONCLUSIONS: Analysis of the case-mix of procedures revealed that an overall positive margin between costs and DRG reimbursements was achieved. It therefore emerges that adherence to the indications of the Healthcare Agency of the Emilia Romagna Region for the appropriate clinical use of DESs is economically sustainable from the hospital enterprise point of view, although the DRG reimbursements are not able to differentiate among resource consumptions owing to the adoption of innovative technologies.

A new management of syncope: prospective systematic guideline-based evaluation of patients referred urgently to general hospitals.

AIMS: The guidelines of the European Society of Cardiology (ESC) define the current standard for the management of syncope, but are still incompletely applied in the clinical setting. METHODS AND RESULTS: Prospective systematic evaluation, on strict adherence to the guidelines, of consecutive patients referred for syncope to the emergency departments of 11 general hospitals. In order to maximize the application, a decision-making guideline-based software was used and trained core medical personnel were designated-both locally in each hospital and centrally-to verify adherence to the diagnostic pathway and give advice on its correction. A diagnostic work-up consistent with the guidelines was completed in 465/541 patients (86%). A definite diagnosis was established in 98% (unexplained in 2%): neurally mediated syncope accounted for 66% of diagnosis, orthostatic hypotension 10%, primary arrhythmias 11%, structural cardiac or cardiopulmonary disease 5%, and non-syncopal attacks 6%, respectively. The initial evaluation (consisting of history, physical examination, and standard electrocardiogram) established a diagnosis in 50% of cases. Hospitalization for the management of syncope was appropriate in 25% and was required for other reasons in a further 13% of cases. The median in-hospital stay was 5.5 days (interquartile range, 3-9). Apart from the initial evaluation, a mean of 1.9+/-1.1 appropriate tests per patient was performed in 193 patients and led to a final diagnosis in 182 of these (94%). CONCLUSION: The results of this study assess the current standard for the management of syncope on the basis of a rigorous adherence to guidelines of the ESC and provide a frame of reference for daily activity when dealing with syncope.
