Markers of Risk of Asthma Death or Readmission in the 12 Months Following a Hospital Admission for Asthma
Why the study?
Do markers of asthma severity predict asthma death or readmission in patients aged 5-45 years following a hospital admission for asthma?
Population
528 people aged 5-45 years who had a hospital admission for asthma in New Zealand during 1981-1987…
Comparison
Markers of asthma severity vs Absence of these markers

Implication
Recent admission flags high-risk asthma patients for closer monitoring; supports risk stratification but leaves open prospective validation.
Structured PICO
Do markers of asthma severity predict asthma death or readmission in patients aged 5-45 years following a hospital admission for asthma?
P
Population
528 people aged 5-45 years who had a hospital admission for asthma (index admission) in New Zealand during 1981-1987, excluding those prescribed fenoterol. Comprises 39 who died of asthma, 226 readmitted for asthma, and 263 controls.
I
Intervention
Markers of asthma severity (prior admission in previous 12 months, prescription of 3 or more categories of asthma drugs, prescription of oral corticosteroids)
C
Comparator
Absence of these markers
O
Outcome
Asthma death or hospital readmission for asthma during the 12 months after index admissionhard clinical
A previous hospital admission for asthma within 12 months is a strong predictor of subsequent asthma death or readmission.
