title: Hospital admissions for non-cystic fibrosis bronchiectasis in New Zealand.
abstract: OBJECTIVE
  To investigate hospital admissions for non-cystic fibrosis bronchiectasis during July 1, 2008 to June 30, 2013; and to describe their distribution and annual cost in New Zealand.
  
  
  METHODS
  Admissions with a principal diagnosis of bronchiectasis (ICD10 J47), excluding cystic fibrosis, and length of stay <90 days were analysed by age, sex, ethnicity, socioeconomic deprivation, DHB, re-admissions and seasonality.
  
  
  RESULTS
  There were 5,494 admissions with a mean annual rate of 25.7 (age adjusted rate 20.4) per 100,000. Admission rates peaked in childhood and in the elderly, and increased steeply with socioeconomic deprivation. Age-adjusted rates were 38% higher for women, 4.9-fold higher for Māori and 9.1-fold higher for Pacific peoples. Counties Manukau had the highest unadjusted rate for any DHB (49.4 per 100,000). The overall 30 day readmission rate was 12.4%. Admissions peaked in winter and spring. The estimated cost in financial year 2012/13 was NZD 5.34M.
  
  
  CONCLUSIONS
  Hospital admissions for bronchiectasis are concentrated in socioeconomically disadvantaged young and elderly Māori and Pacific peoples; are more common in winter and spring, and incur a high annual cost. Evidence-based interventions to reduce the disproportionate burden of bronchiectasis in Māori and Pacific children and the elderly is a public health priority.
