Prognostic Implications of Door-to-Balloon Time and Onset-to-Door Time on Mortality in Patients With ST -Segment-Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention.

ABSTRACT: Background In patients with ST-segment-elevation myocardial infarction, timely reperfusion therapy with door-to-balloon (D2B) time <90 minutes is recommended by the current guidelines. However, whether further shortening of symptom onset-to-door (O2D) time or D2B time would enhance survival of patients with ST-segment-elevation myocardial infarction remains unclear. Therefore, the current study aimed to evaluate the prognostic impact of O2D or D2B time in patients with ST-segment-elevation myocardial infarction who underwent primary percutaneous coronary intervention. Methods and Results We analyzed 5243 patients with ST-segment-elevation myocardial infarction were treated at 20 tertiary hospitals capable of primary percutaneous coronary intervention in Korea. The association between O2D or D2B time with all-cause mortality at 1 year was evaluated. The median O2D time was 2.0 hours, and the median D2B time was 59 minutes. A total of 92.2% of the total population showed D2B time ?90 minutes. In univariable analysis, 1-hour delay of D2B time was associated with a 55% increased 1-year mortality, whereas 1-hour delay of O2D time was associated with a 4% increased 1-year mortality. In multivariable analysis, D2B time showed an independent association with mortality (adjusted hazard ratio, 1.90; 95% CI , 1.51-2.39; P<0.001). Reducing D2B time within 45 minutes showed further decreased risk of mortality compared with D2B time >90 minutes (adjusted hazard ratio, 0.30; 95% CI , 0.19-0.42; P<0.001). Every reduction of D2B time by 30 minutes showed continuous reduction of 1-year mortality (90 to 60 minutes: absolute risk reduction, 2.4%; number needed to treat, 41.9; 60 to 30 minutes: absolute risk reduction, 2.0%; number needed to treat, 49.2). Conclusions Shortening D2B time was significantly associated with survival benefit, and the survival benefit of shortening D2B time was consistently observed, even <60 to 90 minutes.

Project description:BackgroundThe impact of reducing door-to-balloon time on hospital revenues, costs, and net income is unknown.MethodsWe prospectively determined the impact on hospital finances of (1) emergency department physician activation of the catheterization lab and (2) immediate transfer of the patient to an immediately available catheterization lab by an in-house transfer team consisting of an emergency department nurse, a critical care unit nurse, and a chest pain unit nurse. We collected financial data for 52 consecutive ST-elevation myocardial infarction patients undergoing emergency percutaneous intervention from October 1, 2004-August 31, 2005 and compared this group to 80 consecutive ST-elevation myocardial infarction patients from September 1, 2005-June 26, 2006 after protocol implementation.ResultsPer hospital admission, insurance payments (hospital revenue) decreased ($35,043 +/- $36,670 vs. $25,329 +/- $16,185, P = 0.039) along with total hospital costs ($28,082 +/- $31,453 vs. $18,195 +/- $9,242, P = 0.009). Hospital net income per admission was unchanged ($6962 vs. $7134, P = 0.95) as the drop in hospital revenue equaled the drop in costs. For every $1000 reduction in total hospital costs, insurance payments (hospital revenue) dropped $1077 for private payers and $1199 for Medicare/Medicaid. A decrease in hospital charges ($70,430 +/- $74,033 vs. $53,514 +/- $23,378, P = 0.059), diagnosis related group relative weight (3.7479 +/- 2.6731 vs. 2.9729 +/- 0.8545, P = 0.017) and outlier payments with hospital revenue>$100,000 (7.7% vs. 0%, P = 0.022) all contributed to decreasing ST-elevation myocardial infarction hospitalization revenue. One-year post-discharge financial follow-up revealed similar results: Insurance payments: $49,959 +/- $53,741 vs. $35,937 +/- $23,125, P = 0.044; Total hospital costs: $39,974 +/- $37,434 vs. $26,778 +/- $15,561, P = 0.007; Net Income: $9984 vs. $9159, P = 0.855.ConclusionAll of the financial benefits of reducing door-to-balloon time in ST-elevation myocardial infarction go to payers both during initial hospitalization and after one-year follow-up.Trial registrationClinicalTrials.gov ID: NCT00800163.
