Five years of Stent for Life in Portugal.

OBJECTIVE: To analyze changes in performance indicators five years after Portugal joined the Stent for Life (SFL) initiative. METHODS: National surveys were carried out annually over one-month periods designated as study Time Points between 2011 (Time Zero) and 2016 (Time Five). In this study, 1340 consecutive patients with suspected ST-elevation myocardial infarction (STEMI) who underwent coronary angiography, admitted to 18 24/7 primary percutaneous coronary intervention (PCI) centers, were enrolled. RESULTS: There was a significant reduction in the proportion of patients who attended primary healthcare centers (20.3% vs. 4.8%, p<0.001) and non-PCI-capable centers (54.5% vs. 42.5%, p=0.013). The proportions of patients who called 112, the national emergency medical services (EMS) number (35.2% vs. 46.6%, p=0.022) and of those transported via the EMS to a PCI-capable center (13.1% vs. 30.5%, p<0.001) increased. The main improvement observed in timings for revascularization was a trend toward a reduction in patient delay (114 min in 2011 vs. 100 min in 2016, p=0.050). System delay and door-to-balloon time remained constant, at a median of 134 and 57 min in 2016, respectively. CONCLUSION: During the lifetime of the SFL initiative in Portugal, there was a positive change in patient delay indicators, especially the lower proportion of patients who attended non-PCI centers, along with an increase in those who called 112. System delay did not change significantly over this period. These results should be taken into consideration in the current Stent - Save a Life initiative.

Systematic investment in the delivery of guideline-coherent therapy reduces mortality and overall costs in patients with ST-elevation myocardial infarction: Results from the Stent for Life economic model for Romania, Portugal, Basque Country and Kemerovo region.

AIMS: The Stent for Life initiative aims at the reduction of mortality in patients with ST-elevation myocardial infarction by enhancing timely access to primary percutaneous coronary intervention. To assess the associated health and socioeconomic impact, the Stent for Life economic project was launched and applied to four model regions: Romania, Portugal, the Basque Country in Spain, and the Kemerovo region in the Russian Federation. METHODS AND RESULTS: The Stent for Life economic model is based on a decision tree that incorporates primary percutaneous coronary intervention rates and mortality. Healthcare costs and indirect costs caused by loss of productivity were estimated. A baseline scenario simulating the status quo was compared to the Stent for Life scenario which integrated changes initiated by the Stent for Life programme. In the four model regions, primary percutaneous coronary intervention numbers rose substantially between 29-303%, while ST-elevation myocardial infarction mortality was reduced between 3-10%. Healthcare costs increased by 8% to 70%. Indirect cost savings ranged from 2-7%. Net societal costs were reduced in all model regions by 2-4%. CONCLUSION: The joint effort of the Stent for Life initiative and their local partners successfully saves lives. Moreover, the increase in healthcare costs was outweighed by indirect cost savings, leading to a net cost reduction in all four model regions. These findings demonstrate that systematic investments to improve the access of ST-elevation myocardial infarction patients to guideline-coherent therapy is beneficial, not only for the individual, but also for the society at large.

Time to reperfusion in high-risk patients with myocardial infarction undergoing primary percutaneous coronary intervention.

INTRODUCTION: Timely reperfusion with primary percutaneous coronary intervention (PPCI) in ST-segment elevation myocardial infarction (STEMI) improves patient outcomes. In recent years, the Stent for Life (SFL) initiative in Portugal developed an action plan to improve timely access to PPCI. This study aims to evaluate performance indicators in high-risk populations (elderly, female, and diabetic patients). METHODS: Data on 1340 patients with suspected STEMI who were admitted to 18 Portuguese interventional cardiology centers were collected during a one-month period every year from 2011 to 2016. The risk of longer patient and system delay in elderly, female, and diabetic patients was assessed by logistic regression analysis. RESULTS: Patient and system delays were longer in elderly patients (incremental median 32 and 40 min; p=0.001 and p<0.001, respectively). Median system delay was also longer in women (incremental median 25 min; p<0.001). Consequently, times to revascularization were longer in elderly patients (incremental median 92 min; p<0.001) and women (incremental median 67 min; p<0.001). There was no significant difference in reperfusion delay in diabetic patients. After adjustment for gender and diabetes, elderly age was an independent predictor of patient delay longer than the median (OR 1.64; 95% CI 1.22-2.20; p=0.001) and system delay >90 min (OR 2.95; 95% CI 1.84-4.72; p<0.001). CONCLUSION: Elderly patients showed longer patient and system delays, regardless of gender and presence of diabetes. These data suggest that the elderly subgroup should be the target of a new action by the SFL initiative.

The Stent for Life initiative: Factors predicting system delay in patients with ST-segment elevation myocardial infarction.

INTRODUCTION AND AIMS: System delay (time between first medical contact and reperfusion therapy) is an indicator of quality of primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) patients. This study aimed to assess changes in system delay between 2011 and 2015, and to identify its predictors. METHODS: The study included 838 patients admitted to 18 Portuguese interventional cardiology centers suspected of having STEMI with less than 12 hours' duration who were referred for primary percutaneous coronary intervention. Data were collected for a one-month period every year from 2011 to 2015. Univariate and multivariate logistic regression models were used to determine predictors of system delay. RESULTS: No significant changes in system delay were observed during the study. Only 27% of patients had a system delay of ≤90 min. Multivariate analysis identified four predictors of system delay: age ≥75 years (OR 2.57; 95% CI 1.50-4.59; p=0.001), attending a center without pPCI (OR 4.08; 95% CI 2.75-6.10; p<0.001), not calling the national medical emergency number (112) (OR 0.47; 95% CI 0.32-0.68; p<0.001), and Central region (OR 3.43; 95% CI 1.60-8.31; p=0.003). CONCLUSIONS: The factors age ≥75 years, attending a center without pPCI, not calling 112, and Central region were identified as predicting longer system delay. This knowledge may help in planning interventions to reduce system delay and to improve the clinical outcomes of patients with STEMI.

Factors influencing patient delay before primary percutaneous coronary intervention in ST-segment elevation myocardial infarction: The Stent for life initiative in Portugal.

INTRODUCTION AND AIMS: Shorter patient delays are associated with a better prognosis for patients diagnosed with ST-segment elevation myocardial infarction (STEMI). This study aimed to identify predictors of patient delay in the Portuguese population. METHODS: Data on 994 patients with suspected STEMI of less than 12 hours' duration and referred for primary percutaneous coronary intervention (pPCI) and admitted to 18 Portuguese interventional cardiology centers were collected for a one-month period every year from 2011 to 2015. Univariate and multivariate linear regression models were used to identify predictors of patient delay. RESULTS: No significant differences were observed in patient delay over the course of the survey. The multivariate analysis identified five predictors of patient delay: age ≥75 years (exp[beta] 1.28; 95% CI 1.10-1.50; p=0.001), symptom onset between 0:00 and 8:00 a.m. (exp[beta] 1.26; 95% CI 1.10-1.45; p=0.001), and attending a primary care unit before first medical contact (exp[beta] 1.75; 95% CI 1.41-2.16; p<0.001) predicted longer patient delay, while calling the national medical emergency number (112) (exp[beta] 0.84; 95% CI 0.71-1.00; p=0.045) and transport by the emergency medical services to the pPCI facility (exp[beta] 0.71; 95% CI 0.59-0.84; p<0.001) predicted shorter patient delay. CONCLUSIONS: We identified five factors predicting patient delay, which will help in planning interventions to reduce patient delays and to improve the outcome of patients with STEMI.

Stent for Life in Portugal: This initiative is here to stay.

AIMS: Portugal has one of the lowest rates of primary percutaneous coronary intervention (p-PCI) in Western Europe. This study assessed the progress of Portuguese p-PCI performance indicators one year after Portugal joined the Stent for Life (SFL) initiative. METHODS AND RESULTS: Two national surveys were carried out, each covering a period of one month: the first when Portugal joined the SFL in 2011 (Moment Zero), and the second one year later (Moment One). A total of 397 consecutive patients with probable ST-segment elevation myocardial infarction were enrolled (201 at Moment Zero and 196 at Moment One) from 15 centers. During this period, the number of patients who arrived at a local hospital without p-PCI decreased (62-47%; p=0.004) and transportation to a p-PCI hospital by the National Institute for Medical Emergencies (INEM) increased significantly (13-37%; p<0.001). Shorter times to revascularization were observed, due to shorter patient delay (118-102 min; p=0.008). Door-to-balloon delay and system delay remained unchanged. CONCLUSIONS: Improvements in performance indicators for p-PCI demonstrate the success of the first year of the local SFL plan, which was mainly focused on raising public awareness of the need to use the INEM emergency services, which has reduced patient delay, and on improving secondary transportation.
