Volcanic disruption: the impact of Whakaari White Island on the provision of elective surgical care in Counties Manukau.

Abstract

On 9 December 2019, Whakaari White Island erupted while 47 people were on the island. Thirty-one people were subsequently hospitalized. Fourteen volcanic burn victims were managed at the National Burns Centre at Middlemore Hospital. Between December 2019 and March 2020 these patients required 124 procedures in theatre, using 23 709 operative minutes. Elective surgical lists were cancelled to fulfil this demand for acute operating theatre time and theatre staff. To quantify the elective surgical resource lost in the aftermath of the Whakaari White Island eruption by surgical specialty. A data set listing all surgical procedures undertaken within Counties Manukau District Health Board during the period 1 December 2019-1 March 2020 and the corresponding months from the preceding 3 years was analysed. Sum operating time and procedures post-Whakaari were compared with the average of the prior 3 years to quantify loss in resource. In the 3 months post-Whakaari, 698 fewer elective operations were completed across all surgical specialties than the average of the previous 3 years, a decrease of 26.3%. All major surgical specialties except urology showed an absolute decrease in elective procedures completed. The most significant decrease was the 59.1% (533 procedures) loss in plastic surgery elective procedures, with no sign of recovery by March 2021. The plastic surgery department was the worst affected by the Whakaari disaster. Overall elective surgical delivery within Counties Manukau was substantially impacted, and would not yet recover by the time of the national COVID-19 lockdown in March 2020.
