Background.
Asthma caused substantial economic and health care burden and is susceptible to air pollution.
Particularly, when it comes to elder asthma patient (older than 65), the phenomenon is more significant.
The aim of this study is to investigate the Markov-based acute effects of air pollution on elder asthma hospitalizations, in forms of transition probabilities.
Methods.
A retrospective, population-based study design was used to assess temporal patterns in hospitalizations for asthma in a region of Sichuan province, China.
Approximately 12 million residents were covered during this period.
Relative risk analysis and Markov chain model were employed on daily hospitalization state estimation.
Results.
Among PM2.5, PM10, NO2, and SO2, only SO2 was significant.
When air pollution is severe, the transition probability from a low-admission state (previous day) to high-admission state (next day) is 35.46%, while it is 20.08% when air pollution is mild.
In particular, for female-cold subgroup, the counterparts are 30.06% and 0.01%, respectively.
Conclusions.
SO2 was a significant risk factor for elder asthma hospitalization.
When air pollution worsened, the transition probabilities from each state to high admission states increase dramatically.
This phenomenon appeared more evidently, especially in female-cold subgroup (which is in cold season for female admissions).
Based on our work, admission amount forecast, asthma intervention, and corresponding healthcare allocation can be done.
