Temporal Trends in Acute Mental Health Problems during the Emergency Medical Team Response to Cyclone Idai 2019 in Mozambique: Findings from the WHO Emergency Medical Team Minimum Data Set

In 2017, the World Health Organization introduced an international standardized medical data collection tool for disasters, known as the Emergency Medical Team (EMT) Minimum Data Set (MDS). The EMT MDS was activated for the first time in 2019 in response to Cyclone Idai in Mozambique. The present study aimed to examine the daily and phase trends in acute mental health problems identified by international EMTs during their response to Cyclone Idai and reported using the EMT MDS.

Joinpoint regression analysis was used to examine daily trends in acute mental health consultations. Trends were also examined by phases, which were identified using joinpoints.

During the 90-day EMT response period following Cyclone Idai, 94 acute mental health consultations were reported. The daily trend analysis showed a significant increase in the daily number and percentage of acute mental health consultations from response onset until day 13, followed by a gradual decline (P<0.05). The phase trend analysis showed a consistent decrease across the identified phases (P for trend<0.001).

The findings of this study provide insight into the need for mental health support in the immediate aftermath of natural disasters and how that need may change over time.
