Value-Based ST-Segment-Elevation Myocardial Infarction Care Using Risk-Guided Triage and Early Discharge.

ABSTRACT: BACKGROUND:Prior studies suggest that low-risk ST-segment-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention can be considered for early discharge. We describe the implementation of an STEMI risk score to decrease cost while maintaining optimal patient outcomes. METHODS AND RESULTS:We determined the impact of risk-guided STEMI care on healthcare value through the retrospective application of the Zwolle Risk Score to 967 patients receiving primary percutaneous coronary intervention between 2009 and 2011. Of these patients, 540 (56%) were categorized as low risk, indicating they may be safely triaged directly to a telemetry unit rather than the intensive care unit and targeted for early discharge. We subsequently developed and implemented a modified Zwolle Risk Calculator into the electronic medical record to support application of the fast-track protocol for low-risk STEMI patients. Among 549 prospective patients with STEMI, 62% were low risk, and the fast-track protocol was followed in 75% of cases. Prospective results confirmed lower rates of complications (low risk 8.3% versus high risk 38.7%; P<0.001) and in-hospital mortality (low risk 0.4% versus High risk 12.5%; P<0.001) in the low-risk cohort. Low-risk patients had a shorter median length of stay (median and [25th, 75th percentiles]: low risk 2 [2, 3] versus high risk: 3 [2, 6]; P<0.001) and lower overall costs (low risk $6720 [$5280-$9030] versus high risk $11?783 [$7953-$25?359]; P<0.001). Low-risk patients treated on-protocol had shorter median length of stay (on-protocol 2 [1, 2] versus off-protocol 2 [2, 3]; P<0.001) and hospital costs (on-protocol $6090 [$4730, $7356] versus off-protocol $11?783 [$7953, $25?359]; P<0.001) than those treated off-protocol. On-protocol low-risk patients in the prospective cohort also had lower costs and shorter length of stay than low-risk patients in the retrospective cohort (P<0.001 for both). CONCLUSIONS:In our study, risk-guided triage and discharge after primary percutaneous coronary intervention for STEMI improved healthcare value by reducing costs of care without compromising quality of care or patient outcomes.

Project description:ImportanceChallenges to improving ST-segment elevation myocardial infarction (STEMI) care are formidable in low- to middle-income countries because of several system-level factors.ObjectiveTo examine access to reperfusion and percutaneous coronary intervention (PCI) during STEMI using a hub-and-spoke model.Design, setting, and participantsThis multicenter, prospective, observational study of a quality improvement program studied 2420 patients 20 years or older with symptoms or signs consistent with STEMI at primary care clinics, small hospitals, and PCI hospitals in the southern state of Tamil Nadu in India. Data were collected from the 4 clusters before implementation of the program (preimplementation data). We required a minimum of 12 weeks for the preimplementation data with the period extending from August 7, 2012, through January 5, 2013. The program was then implemented in a sequential manner across the 4 clusters, and data were collected in the same manner (postimplementation data) from June 12, 2013, through June 24, 2014, for a mean 32-week period.ExposuresCreation of an integrated, regional quality improvement program that linked the 35 spoke health care centers to the 4 large PCI hub hospitals and leveraged recent developments in public health insurance schemes, emergency medical services, and health information technology.Main outcomes and measuresPrimary outcomes focused on the proportion of patients undergoing reperfusion, timely reperfusion, and postfibrinolysis angiography and PCI. Secondary outcomes were in-hospital and 1-year mortality.ResultsA total of 2420 patients with STEMI (2034 men [84.0%] and 386 women [16.0%]; mean [SD] age, 54.7 [12.2] years) (898 in the preimplementation phase and 1522 in the postimplementation phase) were enrolled, with 1053 patients (43.5%) from the spoke health care centers. Missing data were common for systolic blood pressure (213 [8.8%]), heart rate (223 [9.2%]), and anterior MI location (279 [11.5%]). Overall reperfusion use and times to reperfusion were similar (795 [88.5%] vs 1372 [90.1%]; P = .21). Coronary angiography (314 [35.0%] vs 925 [60.8%]; P < .001) and PCI (265 [29.5%] vs 707 [46.5%]; P < .001) were more commonly performed during the postimplementation phase. In-hospital mortality was not different (52 [5.8%] vs 85 [5.6%]; P = .83), but 1-year mortality was lower in the postimplementation phase (134 [17.6%] vs 179 [14.2%]; P = .04), and this difference remained consistent after multivariable adjustment (adjusted odds ratio, 0.76; 95% CI, 0.58-0.98; P = .04).Conclusions and relevanceA hub-and-spoke model in South India improved STEMI care through greater use of PCI and may improve 1-year mortality. This model may serve as an example for developing STEMI systems of care in other low- to middle-income countries.
