Safety of Tiotropium + Olodaterol in Chronic Obstructive Pulmonary Disease (COPD) Patients in Taiwan: a Non-interventional Study Based on the Taiwan National Health Insurance (NHI) Data

Incidence rate of adverse events in patients with COPD treated with Tiotropium+Olodaterol (Tio+Olo) per number of person-years is reported. From the index date until the earliest: Outcome of interest, disenrollment, the end of the study period, death, discontinuation of the index drug, addition of Inhaled corticosteroids mono on top of Tio/Olo. The incidence rate was reported as (Total number of patients in the Tio+Olo cohort experiencing an event of interest for the 1st time during the given time period) / (Total person-time at risk from current use of Tio+Olo during the given period). Urinary tract infection: (1): Diagnosis codes were primary inpatient diagnosis associated with a hospitalization. (2): Diagnosis codes were primary or secondary diagnosis associated with a hospitalization.(3): Diagnosis codes were primary or secondary diagnosis associated with a hospitalization OR associated with at least 2 outpatient/emergency visits within 30 days of each other.

Categorized as 0, 1, or 2+ according to the frequency of previous acute COPD exacerbation in 1 year for each patient.

Number of participants with comorbidities in 1 year prior to index date according to whether they started Tio+Olo or another LAMA/LABA is reported. The following comorbidities are reported: Cardiovascular disease, Cerebrovascular disease, Diabetes, Chronic kidney disease, Pneumonia, Cancer and Cirrhosis.

Charlson Comorbidity Index (CCI) according to whether they started Tio+Olo or another LAMA/LABA is reported.

The CCI (using Deyo version) is a comorbidity index used to evaluate survival rate in patients with multiple comorbidities. 17 comorbidities were assessed with different weights, and the total score was determined by adding the scores of each comorbidity. The total score goes from 0 to 37, with higher values predicting a higher mortality rate.
