What does the evidence show about the consequences of disasters on diabetes and other chronic conditions? What does this mean for preparedness? (#60)
Disasters are extraordinary events that threaten lives and damage infrastructure, exceeding the local community’s ability to recover without outside assistance. Natural disasters, including bushfires, floods, storms and cyclones are occurring annually in Australia.
Disasters result in acute and chronic health effects, particularly in those with pre-existing medical conditions. Patient with diabetes mellitus are especially vulnerable; not only do they require frequent glycaemic control monitoring and screening for complications, but also commonly have associated comorbidities. The research shows that elevations in HbA1C % levels and insulin requirements may occur post disaster. One of the findings after the 1994 Los Angeles earthquake was an increased incidence of newly diagnosed insulin dependent diabetes mellitus admitted to the Los Angeles Children’s Hospital. Furthermore, glycaemic control in patients with diabetes mellitus can be adversely affected by disasters even many years after the event.
Changes in environment with limited or increased consumption of food, changes in exercise routine, and variable access to medication, refrigeration and monitoring equipment can all contribute to poor diabetic control. Co-morbidities including mental health effects may also affect care. Planning for disaster followed by early medical review with regular check-ups would be expected to improve outcomes after such events.
