Meeting time goals for patients with time-sensitive conditions can be challenging in rural emergency departments (EDs), and adopting policies is critical. ED-based telemedicine has been proposed to improve quality and timeliness of care in rural EDs.
The objective of this study was to test the hypothesis that diagnostic testing in telemedicine-supplemented ED care for patients with myocardial infarction (MI) and stroke would be faster than nontelemedicine care in rural EDs.
This observational cohort study included all ED patients with MI or stroke in 19 rural critical access hospitals served by a single real-time contract-based telemedicine provider in the upper Midwest (2007-2015). The primary outcome for the MI cohort was time-to-electrocardiogram (EKG) and for the stroke cohort was time-to-head computed tomography (CT) interpretation. To measure the relationship between telemedicine and timeliness parameters, generalized estimating equations models were used, clustering on presenting hospital.
Of participating ED visits, 756 were included in the MI cohort (29% used telemedicine) and 140 were included in the stroke cohort (30% used telemedicine). Time-to-EKG did not differ when telemedicine was used (1% faster, 95% confidence interval [CI] -4% to 7%), or after telemedicine was implemented (4% faster, 95% CI -3% to 10%). Head CT interpretation was faster for telemedicine cases (15% faster, 95% CI 4-26%). No differences were observed in time to reperfusion therapy.
Telemedicine implementation was associated with more timely head CT interpretation for rural patients with stroke, but no difference in early MI care. Future work will focus on the specific manner in which telemedicine changes ED care processes and ongoing professional education.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 February 2019.
All research outputs
#24,121,891
of 34,411,289 outputs
Outputs from Telemedicine Journal and e-Health
#1,541
of 2,230 outputs
Outputs of similar age
#252,832
of 374,733 outputs
Outputs of similar age from Telemedicine Journal and e-Health
#17
of 28 outputs
Altmetric has tracked 34,411,289 research outputs across all sources so far. This one is in the 28th percentile – i.e., 28% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,230 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.8. This one is in the 27th percentile – i.e., 27% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 374,733 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 28 others from the same source and published within six weeks on either side of this one. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
