b'The bars in each figure represent communities with populations ranging from 100,000 to over 3 million. The red dotted line denotes the national average for benchmarking purposes (overall survival: 10.5%; Utstein survival: 33.4%; bystander CPR: 41.7%), while the grey vertical lines indicate quartile cut points. PUBLIC REPORTING OF STATE AGGREGATE METRICSSurvival after out-of-hospital cardiac arrest varies across regions in the United States. With an increasing number of CARES state participants, there is a unique opportunity to present aggregate metrics by state, allowing for a better understanding of OHCA incidence, survival outcomes, and bystander intervention rates nationwide. Table 4 presents aggregate metrics for state participants that had at least 50% population catchment in 2024. A total of 22 states and the District of Columbia voluntarily agreed to participate in reporting these metrics.The included states have a wide range of both population catchment (from 590,952 to over 32 million) and incidence rates (from 57.4121.4 per 100,000; a 2.1-fold difference). There is also marked variability in community interventions, with bystander CPR rates ranging from 23.479.7% (a 3.4-fold difference) and public AED use rates ranging from 5.821.4% (a 3.7-fold difference), as well as patient outcomes (overall survival: 7.515.7% (2.1-fold difference); Utstein survival: 11.745.0% (3.8-fold difference)).OHCA Incidence Non-Traumatic EtiologyBystander Intervention Survival Rates Rates CARES CasesCARESTotal State% PopulationIncidence RateOverall SurvivalUtstein Public AED Use Reported PopulationPopulation Covered (per 100,000) to HospitalSurvival (%) CPR (%) (%)Catchment Discharge (%)National 137,119 174,141,709 334,914,895 52.0% 78.7 10.5 33.4 41.7 12.6StateAlaska 527 590,952 733,406 80.6% 89.2 12.3 35.1 79.7 16.1California 24,008 32,535,740 38,965,193 83.5% 73.8 8.7 31.7 42.0 9.9Colorado 3,500 4,852,658 5,877,610 82.6% 72.1 12.6 36.3 43.0 16.4Connecticut 1,888 2,836,386 3,617,176 78.4 66.6 8.7 40.8 23.8 10.3Delaware 1,253 1,031,890 1,031,890 100.0% 121.4 13.8 45.0 34.4 14.9Florida 10,437 11,731,223 22,610,726 51.9% 89.0 12.3 31.8 39.5 14.1Hawaii 1,560 1,435,138 1,435,138 100.0% 108.7 13.0 34.9 43.8 18.2Kansas 1,407 1,813,183 2,940,546 61.7% 77.6 11.9 34.9 50.8 12.6Maine 1,352 1,395,722 1,395,722 100.0% 96.9 8.5 23.6 50.6 11.1Michigan 8,632 8,849,839 10,037,261 88.2% 97.5 9.0 30.5 40.0 12.8Minnesota 3,478 5,276,497 5,737,915 92.0% 65.9 11.5 35.0 36.8 12.3Missouri 2,829 3,325,545 6,196,156 53.7% 85.1 10.3 31.2 37.8 10.9Montana 656 1,132,812 1,132,812 100.0% 57.9 11.3 36.2 49.3 10.8Nebraska 661 1,152,390 1,978,379 58.3% 57.4 15.7 42.2 46.3 21.4Nevada 2,309 3,004,759 3,194,176 94.1% 76.8 14.0 42.2 57.5 19.0North Carolina 8,471 9,803,971 10,835,491 90.5% 86.4 11.5 30.8 44.4 13.9Oregon 2,919 3,933,331 4,233,358 92.9% 74.2 13.4 37.0 54.6 11.5Pennsylvania 7,277 9,021,953 12,961,683 69.6% 80.7 9.3 33.4 37.1 17.2Utah 1,915 3,267,846 3,417,734 95.6% 58.6 14.1 42.8 48.1 13.3Vermont 587 647,464 647,464 100.0% 90.7 7.8 11.7 46.4 5.8Washington 5,188 7,631,371 7,812,880 97.7% 68.0 14.1 40.8 53.6 13.0Wisconsin 2,882 3,791,731 5,910,955 64.2% 76.0 10.3 34.7 34.3 12.6District of751 678,972 678,972 100.0% 110.6 7.5 37.5 40.2 7.0ColumbiaCARES extends its sincere appreciation to the state participants who voluntarily contributed data for public reporting.
