    from week-0 to week-24

  • Percentage of patients who achieved >0%, ≥25%, ≥50%, 100% OCS reduction of daily maintenance OCS dose from week-0 to week-24 respectively.

    (the number of patients who achieved \>0%, ≥25%, ≥50%, 100% OCS reduction of daily maintenance OCS dose) / (number of total patients ) x 100

    from week-0 to week-24

  • Total amount of maintenance OCS prescribed during outcome period.

    from index date to 24 weeks later

  • Percentage reduction on daily dose of maintenance OCS from week-0 to week-24 with two groups.

    Two groups are amount of regular OCS use at index date is ①5mg/day or more and ②10mg/day or more respectively.

    from week-0 to week-24

  • Total amount of SCS during outcome period.

    from index date to 24 weeks later

Secondary Outcomes (2)

    from week-0 to week-8.

  • Percentage of OCS reduction of maintenance OCS dose from week-0 to week-16.

    from week-0 to week-16

Other Outcomes (9)

  • Percentage reduction on daily dose of maintenance OCS from week-0 to week-24 between benralizumab or mepolizumab initiated severe asthma patients with regular maintenance OCS use and BIO non-initiated severe asthma patients with regular.

    from week-0 to week-24

  • Total amount of maintenance OCS prescribed during one year and two years respectively.

    during one year and two years

  • Total amount of SCS during one year and two year respectively.

Study Population

All individuals who meet followed inclusion / exclusion criteria will be identified between study period in the MDV database, and will be included in Full Analysis Set.

You may qualify if:

  • Patients aged ≥16 years at index date.
  • Patients with records of receiving high dose ICS or high dose ICS/LABA and diagnosed as asthma (ICD-10 code: J45 or J46 ) during baseline period. High dose ICS and high dose ICS/LABA will be defined in the appendices (Table 6-9).
  • Patients who had visit histories at least one visit during baseline period, at least two visits during outcome period and at least one visit after outcome period.
  • Patients who had a total of 12 weeks of OCS prescribed during the baseline period including the index date.

You may not qualify if:

  • \. Patients diagnosed with selected autoimmune diseases during the baseline period because OCS is used as a therapeutic agent for these disease. Autoimmune disease will be identified by following ICD-10 code (M30, M05, M06, L93, M32, K50, K51, K52, N04).
