Research paper thumbnail of Disability and Physical and Communication-Related Barriers to Health Care Related Services Among Florida Residents: A Brief Report

Disability and Health Journal, 2016

Research has not fully characterized barriers to health care faced by persons with disabilities (... more Research has not fully characterized barriers to health care faced by persons with disabilities (PWD) which constitutes a critical gap given the increased risk of chronic illness faced by PWD. To understand the current barriers to seeking health care-related services for PWD in Florida. The study was based on a random-digit-dial telephone interview survey of respondents aged 18 and over (n = 1429). Multivariable logistic regression assessed the relationship between disability and physical and communication barriers. One thousand four hundred and twenty-nine Florida residents participated in the survey. Thirty-three percent of respondents (n = 471) reported having a disability. PWD were significantly older (mean age 68 vs. 61) and had lower levels of income and education than persons without disabilities (PWOD) (p < 0.05). In adjusted analyses, PWD had significantly higher odds of encountering a physical environment barrier (Odds Ratio [OR] = 16.6 95% CI: 7.9, 34.9), a clinical experience barrier (OR = 13.9 95% CI: 6.9, 27.9) a communication and knowledge barrier (OR = 6.7 95% CI: 4.0, 11.3) and a barrier coordinating care (OR = 5.7 95% CI: 3.4, 9.6) compared to persons without disabilities (PWOD). PWD disproportionately face health care access difficulties that can impede the receipt of high quality care within and between provider visits. Efforts to reduce physical barriers and improve communication between providers and PWD may improve functional status and quality of life for these patients.

These directions are numerically represented by basis sets of mutually orthogonal Gram-Schmidt vectors, whose statistical properties may depend on the chosen phase space-time domain of a trajectory. We examine the degree of stability and localization of Gram-Schmidt vector sets simulated with trajectories of a model three-atom Lennard-Jones cluster. Distributions of finite-time Lyapunov exponent and inverse participation ratio spectra formed from short-time histories reveal that ergodicity begins to emerge on different time scales for trajectories spanning different phase-space regions, in a narrow range of total energy and history length. Over a range of history lengths, the most localized directions were typically the most unstable and corresponded to atomic configurations near potential landscape saddles.
