Temperature extremes, becoming increasingly frequent due to growing global climate change, are associated with higher rates of missed primary care appointments, according to a recently published study from Drexel University researchers in the American Journal of Preventive Medicine.

The researchers found that rates of missed appointments increased by 0.72% for every 1°F decrease in daily maximum temperatures below 39°F and increased by 0.64% for every 1°F increase above 89°F. Patients 65 and older and those with chronic conditions had stronger associations with an increased rate of missed appointments.

“These findings should be a clarion call for clinical teams, including their practice managers to adapt to ensure care access for patients before the problem gets worse,” said senior author Nathalie S. May, MD, a professor in Drexel University College of Medicine.
