Trends in Reoperative Coronary Artery Bypass Graft Surgery for Older Adults in the United States, 1998 to 2017.

ABSTRACT: Background The likelihood of undergoing reoperative coronary artery bypass graft surgery (CABG) is important for older patients who are considering first-time CABG. Trends in the reoperative CABG for these patients are unknown. Methods and Results We used the Medicare fee-for-service inpatient claims data of adults undergoing isolated first-time CABG between 1998 and 2017. The primary outcome was time to first reoperative CABG within 5 years of discharge from the index surgery, treating death as a competing risk. We fitted a Cox regression to model the likelihood of reoperative CABG as a function of patient baseline characteristics. There were 1 666 875 unique patients undergoing first-time isolated CABG and surviving to hospital discharge. The median (interquartile range) age of patients did not change significantly over time (from 74 [69-78] in 1998 to 73 [69-78] in 2017); the proportion of women decreased from 34.8% to 26.1%. The 5-year rate of reoperative CABG declined from 0.77% (95% CI, 0.72%-0.82%) in 1998 to 0.23% (95% CI, 0.19%-0.28%) in 2013. The annual proportional decline in the 5-year rate of reoperative CABG overall was 6.6% (95% CI, 6.0%-7.1%) nationwide, which did not differ across subgroups, except the non-white non-black race group that had an annual decline of 8.5% (95% CI, 6.2%-10.7%). Conclusions Over a recent 20-year period, the Medicare fee-for-service patients experienced a significant decline in the rate of reoperative CABG. In this cohort of older adults, the rate of declining differed across demographic subgroups.

Project description:ImportanceImprovements in insurance coverage and access to care have resulted from the Affordable Care Act (ACA). However, a focus on short-term pre- to post-ACA changes may distract attention from longer-term trends in unmet health needs, and the problems that persist.ObjectiveTo identify changes from 1998 to 2017 in unmet need for physician services among insured and uninsured adults aged 18 to 64 years in the United States.Design, setting, and participantsSurvey study using 20 years of data, from January 1, 1998, to December 31, 2017, from the Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System to identify trends in unmet need for physician and preventive services.Main outcomes and measuresThe proportion of persons unable to see a physician when needed owing to cost (in the past year), having no routine checkup for those in whom a routine checkup was likely indicated (within 2 years), or failing to receive clinically indicated preventive services (in the recommended timeframe), overall and among subgroups defined by the presence of chronic illnesses and by self-reported health status. We estimated changes over time using logistic regression controlling for age, sex, race, Census region, employment status, and income.ResultsAmong the adults aged 18 to 64 years in 1998 (n = 117 392) and in 2017 (n = 282 378) who responded to the Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System (mean age was 39.2 [95% CI, 39.0-39.3]; 50.3% were female; 65.9% were white), uninsurance decreased by 2.1 (95% CI, 1.6-2.5) percentage points (from 16.9% to 14.8%). However, the adjusted proportion unable to see a physician owing to cost increased by 2.7 (95% CI, 2.2-3.8) percentage points overall (from 11.4% to 15.7%, unadjusted); by 5.9 (95% CI, 4.1-7.8) percentage points among the uninsured (32.9% to 39.6%, unadjusted) and 3.6 (95% CI, 3.2-4.0) percentage points among the insured (from 7.1% to 11.5%, unadjusted). The adjusted proportion of persons with chronic medical conditions who were unable to see a physician because of cost also increased for most conditions. For example, an increase in the inability to see a physician because of cost for patients with cardiovascular disease was 5.9% (95% CI, 1.7%-10.1%), for patients with elevated cholesterol was 3.5% (95% CI, 2.5%-4.5%), and for patients with binge drinking was 3.1% (95% CI, 2.3%-3.3%). The adjusted proportion of chronically ill adults receiving checkups did not change. While the adjusted share of people receiving guideline-recommended cholesterol tests (16.8% [95% CI, 16.1%-17.4%]) and flu shots (13.2% [95% CI, 12.7%-13.8%]) increased, the proportion of women receiving mammograms decreased (-6.7% [95% CI, -7.8 to -5.5]).Conclusions and relevanceDespite coverage gains since 1998, most measures of unmet need for physician services have shown no improvement, and financial access to physician services has decreased.

Project description:Background There are limited contemporary data on the use of emergent coronary artery bypass grafting (CABG) in acute myocardial infarction. Methods and Results Adult (aged >18 years) acute myocardial infarction admissions were identified using the National (Nationwide) Inpatient Sample (2000-2017) and classified by tertiles of admission year. Outcomes of interest included temporal trends of CABG use; age-, sex-, and race-stratified trends in CABG use; in-hospital mortality; hospitalization costs; and hospital length of stay. Of the 11 622 528 acute myocardial infarction admissions, emergent CABG was performed in 1 071 156 (9.2%). CABG utilization decreased overall (10.5% [2000] to 8.7% [2017]; adjusted odds ratio [OR], 0.98 [95% CI, 0.98-0.98]; P<0.001), in ST-segment-elevation myocardial infarction (10.2% [2000] to 5.2% [2017]; adjusted OR, 0.95 [95% CI, 0.95-0.95]; P<0.001) and non-ST-segment-elevation myocardial infarction (10.8% [2000] to 10.0% [2017]; adjusted OR, 0.99 [95% CI, 0.99-0.99]; P<0.001), with consistent age, sex, and race trends. In 2012 to 2017, compared with 2000 to 2005, admissions receiving emergent CABG were more likely to have non-ST-segment-elevation myocardial infarction (80.5% versus 56.1%), higher rates of noncardiac multiorgan failure (26.1% versus 8.4%), cardiogenic shock (11.5% versus 6.4%), and use of mechanical circulatory support (19.8% versus 18.7%). In-hospital mortality in CABG admissions decreased from 5.3% (2000) to 3.6% (2017) (adjusted OR, 0.89; 95% CI, 0.88-0.89 [P<0.001]) in the overall cohort, with similar temporal trends in patients with ST-segment-elevation myocardial infarction and non-ST-segment-elevation myocardial infarction. An increase in lengths of hospital stay and hospitalization costs was seen over time. Conclusions Utilization of CABG has decreased substantially in acute myocardial infarction admissions, especially in patients with ST-segment-elevation myocardial infarction. Despite an increase in acuity and multiorgan failure, in-hospital mortality consistently decreased in this population.

Project description:ObjectiveTo characterize the contemporary efficacy and utilization patterns of coronary artery bypass grafting (CABG) in specific cancer types.MethodsWe leveraged the data from the National Inpatient Sample and plotted trends of utilization and outcomes of isolated CABG (with no other additional surgeries during the same hospitalization) procedures from January 1, 2003, through September 1, 2015. Propensity score matching was used to assess for potential differences in outcomes by type of cancer status among contemporary (2012-2015) patients.ResultsOverall, the utilization of CABG decreased over time (250,677 in 2003 vs 134,534 in 2015, P<.001). However, the proportion of those with comorbid cancer increased (7.0% vs 12.6%, P<.001). Over time, in-hospital mortality associated with CABG use in cancer remained unchanged (.9% vs 1.0%, P=.72); yet, cancer patients saw an increase in associated major bleeding (4.5% vs 15.3%, P<.001) and rate of stroke (.9% vs 1.5%, P<.001) over time. In-hospital cost-of-care associated with CABG-use in cancer also increased over time ($29,963 vs $33,636, P<.001). When stratified by cancer types, in-hospital mortality was not higher in breast, lung, prostate, colon cancer, or lymphoma versus non-cancer CABG patients (all P>.05). However, there was a significantly higher prevalence of major bleeding but not stroke in patients with breast and prostate cancer only compared with non-cancer CABG patients (P<.01). Discharge dispositions were not found to be different between cancer sub-groups and non-cancer patients (P>.05), except for breast cancer patients who had lower home care, but higher skilled care disposition (P<.001).ConclusionAmong those undergoing CABG, the prevalence of comorbid cancer has steadily increased. Outside of major bleeding, these patients appear to share similar outcomes to those without cancer indicating that CABG utilization should be not be declined in cancer patients when otherwise indicated. Further research into the factors underlying the decision to pursue CABG in specific cancer sub-groups is needed.
