Out of hospital sudden cardiac death in Italy: a population-based case-control study.

BACKGROUND: Sudden cardiac death (SCD) is a major cause of death in western countries, with coronary heart disease (CHD) being the basis of over 70% of SCD. Incidence in high-CHD risk countries has already been studied, but this information is not available for Mediterranean low-CHD risk countries. Incidence is of paramount importance when cost-effectiveness rate of actions against SCD must be estimated. METHODS: We estimated the incidence of SCD and its potential risk associated with clinical variables, by a means of a case-control study in a general practice setting. The enrolled general practitioners (GPs) provided data about the total number of their patients, and identified all their patients who suffered an out-of-hospital SCD during the previous 365 days. Two age-matched and gender-matched controls visiting GPs office after the SCD selection were also selected. We used a structured questionnaire to obtain information about potential risk factors for SCD. Covariates that were univariately associated with SCD were included in the multivariate regression analyses. RESULTS: In a population of 297 340 (age greater than 14 years), a total of 230 cases were identified (0.77 per 1000 individuals), mostly occurring at home and among persons with known high cardiovascular risk. In the multivariate analysis only CHD (OR: 1.67; 95% CI: 1.09-2.58), arrhythmia (OR: 2.2; 95% CI: 1.3-3.9), obesity (OR: 2.3; 95% CI: 1.5-3.6), alcohol abuse (OR: 1.8; 95% CI: 1.2-2.7), and family history of CHD (OR 3.1; 95% CI: 1.8-5.3) resulted in a significant association with SCD. CONCLUSIONS: The incidence of SCD in Italy is lower than that reported in high-CHD risk population, most of the cases occurring at home and among persons with known high cardiovascular risk. Implementing recommendations for these patients seems to be the most effective strategy to reduce the incidence of SCD.

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.

Standardized-care pathway vs. usual management of syncope patients presenting as emergencies at general hospitals.

AIMS: The study hypothesis was that a decision-making approach improves diagnostic yield and reduces resource consumption for patients with syncope who present as emergencies at general hospitals. METHODS AND RESULTS: This was a prospective, controlled, multi-centre study. Patients referred from 5 November to 7 December 2001 were managed according to usual practice, whereas those referred from 4 October to 5 November 2004 were managed according to a standardized-care pathway in strict adherence to the recommendations of the guidelines of the European Society of Cardiology. In order to maximize its 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 correct application. The 'usual-care' group comprised 929 patients and the 'standardized-care' group 745 patients. The baseline characteristics of the two study populations were similar. At the end of the evaluation, the standardized-care group was seen to have a lower hospitalization rate (39 vs. 47%, P=0.001), shorter in-hospital stay (7.2+/-5.7 vs. 8.1+/-5.9 days, P=0.04), and fewer tests performed per patient (median 2.6 vs. 3.4, P=0.001) than the usual-care group. More standardized-care patients had a diagnosis of neurally mediated (65 vs. 46%, P=0.001) and orthostatic syncope (10 vs. 6%, P=0.002), whereas fewer had a diagnosis of pseudo-syncope (6 vs. 13%, P=0.001) or unexplained syncope (5 vs. 20%, P=0.001). The mean cost per patient and the mean cost per diagnosis were 19 and 29% lower in the standardized-care group (P=0.001). CONCLUSION: A standardized-care pathway significantly improved diagnostic yield and reduced hospital admissions, resource consumption, and overall costs.

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.

Diagnostic pathway of syncope and analysis of the impact of guidelines in a district general hospital. The ECSIT study (epidemiology and costs of syncope in Trento).

BACKGROUND: The ECSIT study was aimed at evaluating the hospital management of syncope patients, at comparing the appropriateness and costs of the hospital diagnostic pathway before (phase 1) and after (phase 2) the introduction of new guidelines and at analyzing the physicians' compliance to the guidelines. METHODS: All syncope patients admitted to the emergency room between August 1 and October 31, 1999 (phase 1) and between March 1 and May 31, 2000 (phase 2) were enrolled and their clinical records were analyzed in a blind fashion. RESULTS: During the study 538 consecutive patients came to the emergency room for syncope with a hospitalization rate of 53% in phase 1 (n = 151) and of 42% in phase 2 (n = 107). The in-hospital stay increased from 9 days in phase 1 to 11.3 days in phase 2 and diagnostic tests from 2.6 per patient (phase 1) to 2.9 per patient (phase 2) with total costs that rose from [symbol: see text] 3,474 to [symbol: see text] 3,647. Patients with no diagnosis decreased from 51 to 45.8% and the principal causes were identified as vascular brain disease (36.1 vs 33.7%) and neurally-mediated mechanisms (35.3 vs 42.2%). CONCLUSIONS: Despite the high costs of syncope management, the appropriateness and efficacy of the hospital diagnostic pathway remains far from ideal and simply introducing new guidelines seems unable to modify clinical practice.
