Short term exposure to fine particulate matter and hospital admission risks and costs in the Medicare population: time stratified, case crossover study.

ABSTRACT: Objective: To assess risks and costs of hospital admission associated with short term exposure to fine particulate matter with diameter less than 2.5 µm (PM_2.5) for 214 mutually exclusive disease groups.

Design: Time stratified, case crossover analyses with conditional logistic regressions adjusted for non-linear confounding effects of meteorological variables.

Setting: Medicare inpatient hospital claims in the United States, 2000-12 (n=95 277 169).

Participants: All Medicare fee-for-service beneficiaries aged 65 or older admitted to hospital.
