Continuity, Regularity, and Specialty in COPD Care: an Exploration of Long-term Costs and Health Outcomes
Our specific objectives for the present application include:
Objective 1: To describe and assess the excess resource use in patients with COPD, compared with the general population. We will compare the pattern of ambulatory resource use in COPD patients compared with a matched cohort of patients without COPD. Hypothesis a:Individuals with COPD utilize higher amount of ambulatory care services, both for COPD and non-COPD causes, than the general population.
Objective 2 (Specialty in COPD care): To study the association between care provider's specialty and health and cost outcomes in patients with COPD.
Hypothesis a: Controlled for case mix, initiation of care by specialists after discharge from a COPD-related hospitalization episode is associated with a lower risk of short-term readmission and lower short-term COPD-related medical costs, compared with initiation of care by generalists.
Hypothesis b: Controlled for case mix, care provided by experienced generalists is associated with lower long-term all-cause medical costs, compared with provision of care by specialists.
Objective 3 (Continuity and regularity in COPD care): To study the association between continuity and regularity of care and long-term costs and health outcomes of COPD.
Hypothesis a: Controlled for case mix and intensity of care, continuity and regularity of care are associated with lower long-term rates of all-cause hospital admission and lower long-term direct medical costs.
