Healthcare Utilization and Statin Re-Initiation Among Medicare Beneficiaries With a History of Myocardial Infarction.

ABSTRACT: BACKGROUND:Contact with the healthcare system represents an opportunity for individuals who discontinue statins to re-initiate treatment. To help identify opportunities for healthcare providers to emphasize the risk-lowering benefits accrued through restarting statins, we determined the types of healthcare utilization associated with statin re-initiation among patients with history of a myocardial infarction. METHODS AND RESULTS:Medicare beneficiaries with a statin pharmacy fill claim within 30 days of hospital discharge for a myocardial infarction in 2007 to 2012 (n=158 795) were followed for 182 days postdischarge to identify treatment discontinuation, defined as 60 continuous days without statins (n=24 461). Re-initiation was defined as a statin fill within 365 days of the discontinuation date (n=13 136). Using a case-crossover study design and each beneficiary as their own control, healthcare utilization during 0 to 14 days before statin re-initiation (case period) was compared with healthcare utilization 30 to 44 days before statin re-initiation (control period). The mean age of beneficiaries was 75.4 years; 52.8% were women and 81.9% were white. For routine healthcare utilization, the odds ratio (95% confidence interval) for statin re-initiation associated with lipid panel testing was 2.65 (1.93-3.65), outpatient primary care was 1.31 (1.23-1.40), and outpatient cardiologist care was 1.38 (1.28-1.50). For acute healthcare utilization, the odds ratio (95% confidence interval) for statin re-initiation associated with emergency department visits was 1.77 (1.31-2.40), coronary heart disease (CHD) hospitalizations was 3.16 (2.41-4.14) and non-coronary heart disease hospitalizations was 1.73 (1.49-2.01). CONCLUSIONS:The weaker association of routine versus acute healthcare utilization with statin re-initiation suggests missed opportunities to reinforce the importance of statin therapy for secondary prevention.

Project description:ContextPublic reporting of patient outcomes is an important tool to improve quality of care, but some observers worry that such efforts will lead clinicians to avoid high-risk patients.ObjectiveTo determine whether public reporting for percutaneous coronary intervention (PCI) is associated with lower rates of PCI for patients with acute myocardial infarction (MI) or with higher mortality rates in this population.Design, setting, and patientsRetrospective observational study conducted using data from fee-for-service Medicare patients (49,660 from reporting states and 48,142 from nonreporting states) admitted with acute MI to US acute care hospitals between 2002 and 2010. Logistic regression was used to compare PCI and mortality rates between reporting states (New York, Massachusetts, and Pennsylvania) and regional nonreporting states (Maine, Vermont, New Hampshire, Connecticut, Rhode Island, Maryland, and Delaware). Changes in PCI rates over time in Massachusetts compared with nonreporting states were also examined.Main outcome measuresRisk-adjusted PCI and mortality rates.ResultsIn 2010, patients with acute MI were less likely to receive PCI in public reporting states than in nonreporting states (unadjusted rates, 37.7% vs 42.7%, respectively; risk-adjusted odds ratio [OR], 0.82 [95% CI, 0.71-0.93]; P = .003). Differences were greatest among the 6708 patients with ST-segment elevation MI (61.8% vs 68.0%; OR, 0.73 [95% CI, 0.59-0.89]; P = .002) and the 2194 patients with cardiogenic shock or cardiac arrest (41.5% vs 46.7%; OR, 0.79 [95% CI, 0.64-0.98]; P = .03). There were no differences in overall mortality among patients with acute MI in reporting vs nonreporting states. In Massachusetts, odds of PCI for acute MI were comparable with odds in nonreporting states prior to public reporting (40.6% vs 41.8%; OR, 1.00 [95% CI, 0.71-1.41]). However, after implementation of public reporting, odds of undergoing PCI in Massachusetts decreased compared with nonreporting states (41.1% vs 45.6%; OR, 0.81 [95% CI, 0.47-1.38]; P = .03 for difference in differences). Differences were most pronounced for the 6081 patients with cardiogenic shock or cardiac arrest (prereporting: 44.2% vs 36.6%; OR, 1.40 [95% CI, 0.85-2.32]; postreporting: 43.9% vs 44.8%; OR, 0.92 [95% CI, 0.38-2.22]; P = .03 for difference in differences).ConclusionsAmong Medicare beneficiaries with acute MI, the use of PCI was lower for patients treated in 3 states with public reporting of PCI outcomes compared with patients treated in 7 regional control states without public reporting. However, there was no difference in overall acute MI mortality between states with and without public reporting.

Project description:High-intensity statins are recommended following myocardial infarction. However, patients may not continue taking this medication with high adherence.To estimate the proportion of patients filling high-intensity statin prescriptions following myocardial infarction who continue taking this medication with high adherence and to analyze factors associated with continuing a high-intensity statin with high adherence after myocardial infarction.Retrospective cohort study of Medicare patients following hospitalization for myocardial infarction. Medicare beneficiaries aged 66 to 75 years (n?=?29?932) and older than 75 years (n?=?27?956) hospitalized for myocardial infarction between 2007 and 2012 who filled a high-intensity statin prescription (atorvastatin, 40-80 mg, and rosuvastatin, 20-40 mg) within 30 days of discharge. Beneficiaries had Medicare fee-for-service coverage including pharmacy benefits.Sociodemographic, dual Medicare/Medicaid coverage, comorbidities, not filling high-intensity statin prescriptions before their myocardial infarction (ie, new users), and cardiac rehabilitation and outpatient cardiologist visits after discharge.High adherence to high-intensity statins at 6 months and 2 years after discharge was defined by a proportion of days covered of at least 80%, down-titration was defined by switching to a low/moderate-intensity statin with a proportion of days covered of at least 80%, and low adherence was defined by a proportion of days covered less than 80% for any statin intensity without discontinuation. Discontinuation was defined by not having a statin available to take in the last 60 days of each follow-up period.Approximately half of the beneficiaries were women and fourth-fifths were white. At 6 months and 2 years after discharge among beneficiaries 66 to 75 years of age, 17?633 (58.9%) and 10?308 (41.6%) were taking high-intensity statins with high adherence, 2605 (8.7%) and 3315 (13.4%) down-titrated, 5182 (17.3%) and 4727 (19.1%) had low adherence, and 3705 (12.4%) and 4648 (18.8%) discontinued their statin, respectively. The proportion taking high-intensity statins with high adherence increased between 2007 and 2012. African American patients, Hispanic patients, and new high-intensity statin users were less likely to take high-intensity statins with high adherence, and those with dual Medicare/Medicaid coverage and more cardiologist visits after discharge and who participated in cardiac rehabilitation were more likely to take high-intensity statins with high adherence. Results were similar among beneficiaries older than 75 years of age.Many patients filling high-intensity statins following a myocardial infarction do not continue taking this medication with high adherence for 2 years postdischarge. Interventions are needed to increase high-intensity statin use and adherence after myocardial infarction.

Project description:BACKGROUND:Recent policy efforts have focused on improving the value of acute myocardial infarction (AMI) care. Medicare payment programs, for example, increasingly evaluate hospital performance based on spending, as determined by payments made to institutions and providers, and outcome measures for a longitudinal episode of AMI care. Little is known about the relationship between total 30-day payments-both in the inpatient and immediate postdischarge timeframe-and outcomes after an admission for AMI. METHODS AND RESULTS:Using Medicare claims data, we identified Medicare fee-for-service beneficiaries ?65 years of age who were hospitalized at an acute-care hospital for AMI between July 1, 2011, and June 30, 2014, and examined the association between hospital-level 30-day payments for an episode of AMI care and patient 30-day mortality using mixed regression models with a logit link function and random hospital intercepts. Our cohort included 642 105 index hospitalizations for AMI at 2319 acute-care hospitals. Overall mean 30-day episode payments per beneficiary were $22 128 (SD, $1750). The observed 30-day mortality rate was 12.9%. Higher 30-day payments were associated with lower 30-day mortality after adjustment for patient characteristics and comorbidities (adjusted odds ratio for additional $1000 payments, 0.986; 95% confidence interval, 0.979-0.992; P<0.001). Additional adjustment for potential mediating factors, including hospital characteristics, coronary revascularization rates, and discharge disposition, did not significantly attenuate the relationship (adjusted odds ratio for additional $1000 payments, 0.987; 95% confidence interval, 0.980-0.994; P<0.001). CONCLUSIONS:Higher hospital-level 30-day payments-both inpatient and in multiple settings after discharge-for AMI care were associated with lower 30-day mortality among beneficiaries. This may have implications for payment programs that incent reduction in payments without considering value.
