abstract: 'Background Anticoagulation with warfarin represents a
|
|
|
|
|
|
|
|
|
|
transportation-sensitive treatment state. Transportation barrier is a
|
|
|
|
|
|
|
|
|
|
common reason for not using health care services.
|
|
|
|
|
|
|
|
|
|
Objective To assess the association between transportation barriers to
|
|
|
|
|
|
|
|
|
|
anticoagulation clinic and anticoagulation control (AC) among an
|
|
|
|
|
|
|
|
|
|
inner-city, low-income population.
|
|
|
|
|
|
|
|
|
|
Patients/Methods Adults expected to be on chronic warfarin therapy were
|
|
|
|
|
|
|
|
|
|
recruited from an ambulatory anticoagulation clinic. Participants
|
|
|
|
|
|
|
|
|
|
completed a validated questionnaire that assessed transportation
|
|
|
|
|
|
|
|
|
|
barriers to clinic, defined as self-reported trouble getting
|
|
|
|
|
|
|
|
|
|
transportation to a clinic and a composite score of the presence of
|
|
|
|
|
|
|
|
|
|
transportation barriers. Suboptimal AC was defined as time in
|
|
|
|
|
|
|
|
|
|
therapeutic range (TTR) <60\% over 6 months. Prevalence ratios with 95\%
|
|
|
|
|
|
|
|
|
|
confidence intervals (CIs), adjusted for age, sex, and annual household
|
|
|
|
|
|
|
|
|
|
income, described the association of transportation trouble and barriers
|
|
|
|
|
|
|
|
|
|
with AC.
|
|
|
|
|
|
|
|
|
|
Results Of 133 participants, 42.9\% had suboptimal AC. Mean age was 60.4
|
|
|
|
|
|
|
|
|
|
(SD, 13.6) years, and the majority of participants were women (62.2\%).
|
|
|
|
|
|
|
|
|
|
Participants with transportation trouble were more likely to report
|
|
|
|
|
|
|
|
|
|
being disabled/unable to work (63.6\%) and annual household income <\$15
|
|
|
|
|
|
|
|
|
|
000 (45.5\%). Mean TTR was significantly lower for participants with
|
|
|
|
|
|
|
|
|
|
transportation trouble compared to those without (53.8\% {[}SD, 24.7\%]
|
|
|
|
|
|
|
|
|
|
vs 64.7\% {[}SD, 25.0\%]; P = .03). Participants reporting
|
|
|
|
|
|
|
|
|
|
transportation trouble or at least one transportation barrier were 1.60
|
|
|
|
|
|
|
|
|
|
(95\% CI, 1.07-2.39) and 1.68 (95\% CI, 1.01-2.80) times more likely,
|
|
|
|
|
|
|
|
|
|
respectively, to have suboptimal AC compared to those without.
|
|
|
|
|
|
|
|
|
|
Conclusion Inner-city, low-income individuals with transportation
|
|
|
|
|
|
|
|
|
|
barriers were more likely to have suboptimal AC. Further research is
|
|
|
|
|
|
|
|
|
|
warranted to evaluate the impact of alleviating patient-specific
|
|
|
|
|
|
|
|
|
|
transportation barriers on anticoagulation outcomes.'
