Professional overview

Dr. Ji Eun Chang is passionate about understanding the coordination of care within and across organizations. Her research pursuits are centered on exploring the factors that contribute to care continuity, developing a measure for team-based continuity of care, and examining how work is coordinated across the social services and healthcare delivery sectors. Her previous research included exploring coordination across innovative new sites of ambulatory care such as urgent care centers and retail clinics, the integration of community health workers into patient centered medical homes, and developing cancer screening guidelines through a collaborative multi-stakeholder panel. Dr. Chang has also conducted research and evaluation projects across a range of local, federal, and international public and non-profit organizations including the NYC Health and Hospitals, the Community Health Worker Network of NYC, the DC Department of Human Services, the US Department of Health and Human Service, and the South Australian Department of Further Education, Employment, and Training.

In addition to research, Dr. Chang is enthusiastic about developing new courses in the  Public Health Policy and Management program and training students to face the workforce with skills that are both desired and needed in public health organizations.

Abstract
BACKGROUND/OBJECTIVES: Patient activation encompasses the knowledge, skills, and confidence that equip adults to participate actively in their healthcare. Patients with hearing loss may be less able to participate due to poor aural communication. We examined whether difficulty hearing is associated with lower patient activation. DESIGN: Cross-sectional study. SETTING/PARTICIPANTS: A nationally representative sample of Americans aged 65 years and older (n = 13 940) who participated in the Medicare Current Beneficiary Survey (MCBS) during the years 2011 to 2013. MEASUREMENT: Self-reported degree of difficulty hearing (“no trouble,” “a little trouble,” and “a lot of trouble”) and overall activation based on aggregated scored responses to 16 questions from the MCBS Patient Activation Supplement: low activation (below the mean minus 0.5 SDs), high activation (above the mean plus 0.5 SDs), and medium activation (the remainder). Sociodemographic and self-reported clinical measures were also included. RESULTS: “A little trouble” hearing was reported by 5655 (40.6%) of respondents, and “a lot of trouble” hearing was reported by 893 (6.4%) of respondents. Difficulty hearing was significantly associated with low patient activation: in analyses using multivariable multinomial logistic regression, respondents with “a little trouble” hearing had 1.42 times the risk of low vs high activation (95% confidence interval [CI] = 1.27-1.58), and those with “a lot of trouble” hearing had 1.70 times the risk of low vs high activation (95% CI = 1.29-2.11), compared with those with “no trouble” hearing. CONCLUSIONS: Nearly half of people aged 65 years and older reported difficulty hearing, and those reporting difficulty were at risk of low patient activation. That risk rose with increased difficulty hearing. Given the established link between activation and outcomes of care, and in view of the association between hearing loss and poor healthcare quality and outcomes, clinicians may be able to improve care for people with hearing loss by attending to aural communication barriers.

Abstract
Urgent care centers have been identified as one means of shifting care from high-cost emergency departments while increasing after-hours access to care. However, the episodic nature of urgent care also has the potential to fragment care. In this study, we examine the adoption of 2 coordination activities—referrals and the electronic exchange of health information—at urgent care centers and other ambulatory providers across the United States. We find that setting is significantly associated with both health information exchange and referrals. Several organization-level variables and environment-level variables are also related to the propensity to coordinate care.
