Association of early physician follow-up and 30-day readmission after non-ST-segment-elevation myocardial infarction among older patients.

ABSTRACT: Hospital readmission rates within 30 days after acute myocardial infarction are a national performance metric. Previous data suggest that early physician follow-up after heart failure hospitalizations can reduce readmissions; whether these results can be extended to acute myocardial infarction is unclear.We analyzed data from the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines (CRUSADE) Registry linked with Medicare claims from 2003 to 2006 for 25 872 non-ST-segment-elevation myocardial infarction patients ?65 years of age discharged home from 228 hospitals with >25 patients and full revascularization capabilities. After adjusting for patient, treatment, and hospital characteristics, we examined the relationship between hospital-level physician follow-up within 7 days of discharge and 30-day all-cause readmission using logistic regression. The median hospital-level percentage of patients receiving early physician follow-up was 23.3% (interquartile range, 17.1%-29.1%). Among 24 165 patients with Medicare fee-for-service eligibility 30 days after discharge, 18.5% of patients were readmitted within 30 days of index hospitalization. Unadjusted and adjusted rates of 30-day readmission did not differ among quartiles of hospital-level early physician follow-up. Similarly, each 5% increase in hospital early follow-up was associated with an insignificant change in risk for readmission (adjusted odds ratio, 0.99; 95% confidence interval, 0.97-1.02; P=0.60). Sensitivity analyses extended these null findings to 30-day cardiovascular readmissions, high-risk subgroups, and early cardiology follow-up.Although rates of early physician follow-up after acute myocardial infarction varied among US hospitals, hospitals with higher early follow-up rates did not have lower 30-day readmission rates. Targeting strategies other than early physician follow-up may be necessary to reduce readmissions in this population.

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.
