چکیده

Background-utilization of cardiac services varies across regions and hospitals,yet little is known regarding variation in the intensity of outpatient cardiac care across cardiology physician practices or the association with clinical endpoints,an area of potential importance to promote efficient care. methods and results-we included 7 160 732 medicare beneficiaries who received services from 5635 cardiology practices in 2012. beneficiaries were assigned to practices providing the plurality of office visits,and practices were ranked and assigned to quartiles using the ratio of observed to predicted annual payments per beneficiary for common cardiac services (outpatient intensity index). the median (interquartile range) outpatient intensity index was 1.00 (0.81-1.24). mean payments for beneficiaries attributed to practices in the highest (q4) and lowest (q1) quartile of outpatient intensity were: all cardiac payments (q4 $1272 vs q1 $581; ratio,2.2); cardiac catheterization (q4 $215 vs q1 $64; ratio,3.4); myocardial perfusion imaging (q4 $253 vs q1 $83; ratio,3.0); and electrophysiology device procedures (q4 $353 vs q1 $142; ratio,2.5). the adjusted odds ratios (95% ci) for 1 incremental quartile of outpatient intensity for each outcome was: cardiac surgical/procedural hospitalization (1.09 [1.09,1.10]); cardiac medical hospitalization (1.00 [0.99,1.00]); noncardiac hospitalization (0.99 [0.99,0.99]); and death at 1 year (1.00 [0.99,1.00]). conclusion-substantial variation in the intensity of outpatient care exists at the cardiology practice level,and higher intensity is not associated with reduced mortality or hospitalizations. outpatient cardiac care is a potentially important target for efforts to improve efficiency in the medicare population. © 2016 the authors.
