Pre-school wheeze hospital presentations: A demographic profile and review of clinical management.

AIM: Pre-school wheeze is a common hospital presentation in Australasia. The aim of this study was to describe the regional hospital presentation and cost of pre-school wheeze.

METHODS

Audit of children diagnosed with pre-school wheeze at two hospitals in Auckland, New Zealand from October 2017 to September 2019. Guideline adherence was determined.

RESULTS

One hundred and ninety-two children made 247 pre-school wheeze hospital presentations. Pre-school wheeze accounted for a larger proportion of acute hospital presentations for Māori versus non-Māori children (rate ratio 1.76, 95% confidence intervals 1.32-2.31). Hospital representations with pre-school wheeze occurred in 38/192 (20%) children. The proportion with a pre-school wheeze representation was larger for Māori than non-Māori (30% vs. 16%, P = 0.02). Pre-school wheeze event median length of stay increased as household deprivation increased (P = 0.01). Clinical severity of 247 pre-school wheeze episodes was mild (n = 64, 26%), moderate (n = 153, 62%) and severe (n = 30, 12%). Of 244 episodes, inhaled bronchodilators only were given for 149 (61%), oxygen for 54 (22%) and intravenous treatment for 41 (17%). Hospital guideline use was evident in 164/247 (66%) episodes. Neither clinical severity nor treatment intensity varied with child sex, age or ethnicity or household deprivation. The estimated median (interquartile range) direct medical costs of each pre-school wheeze episode were NZ$1279 (NZ$774-2158).

CONCLUSIONS

In Auckland, pre-school wheeze accounts for a larger proportion of acute hospital presentations for Māori compared with non-Māori and Māori children have increased odds of pre-school wheeze readmissions. Length of hospital stay for pre-school wheeze episodes increased with household deprivation. In this audit pre-school wheeze guideline adherence was poor.
