Background:
Although outpatient cardiac rehabilitation (OCR) is associated with improved outcomes post myocardial infarction (MI), authors of limited US studies report OCR travel distance/time estimates with fewer providing rural-urban comparisons.
Objective:
We examined travel distance/time to the closest OCR facility for each Tennessee county.
Methods:
We identified n = 61 Tennessee OCR facilities through a Tennessee Association of Cardiovascular and Pulmonary Rehabilitation list and a data scraping process using cardiac rehabilitation-related keywords. County-level mean travel distance/time to the closest OCR facility was determined using geospatial analysis. We conducted Kruskal-Wallis tests to examine whether mean travel distance/time varied by rural/urban county status and also by MI hospitalization rate status (low, 0 to <33.33 percentile; medium, 33.33 to <66.66 percentile; high, ≥66.66 percentile).
Results:
Of Tennessee's 95 counties, 62.3% of facilities were in its 42 urban counties. Mean (SD) county-level travel distance to the closest OCR was 16.6 (10.0) miles, and mean (SD) county-level travel time was 27.9 (13.6) minutes. Travel distance/time did not significantly differ by rural/urban county status (rural: 15.4 miles, 28.9 minutes; urban: 12.9 miles, 23.2 minutes) or by MI hospitalization rate status (low: 10.4 miles, 19.6 minutes; medium: 14.5 miles, 24.1 minutes; high: 18.8 miles, 30.7 minutes).
Conclusions:
Our findings indicate that overall mean travel distance was around half an hour, but lack of OCR facilities in rural Tennessee counties did not correspond with significantly greater travel distance/time to OCR in rural versus urban counties. Additional efforts are warranted to help patients post-MI with actual or perceived high travel burden navigate personal and structural factors precluding OCR receipt.

01:30Specialized Care Centers and Settings-II
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
