The MCPHD sister's agency is the area hospital that accepts medically underserved patients. With this access to the patient system, the electronic medical records of 21 people meeting the search criteria and seeking care at this emergency department between June 1, 2011, and July 29, 2011 were reviewed. An extended time period was reviewed to see if there were obvious differences in the counts of patients or terminology used in the chief complaint once the heat wave was upon the city. Five (24%) sought care in June 2011, 16 (76%) in July. Fifty percent of those seeking care for heat-related issues were seen in a 2-day period in July. Six people (29%) developed symptoms while at work. Work-related tasks included roofing, painting, working in metal tanks and driving trucks without air conditioning. Two homeless persons (10%) sought care during the 2-day time frame when half of the cases were identified as well as four of the six who developed symptoms while at work. Alcohol and drugs may have been a contributing factor for three (14%) of those seeking care. Nine individuals (43%) were treated for medical conditions, such as chronic obstructive pulmonary disease, diabetes, urinary tract infections, gastrointestinal infections or pneumonia.
