Abstract
Objectives: Patient refusal of transport after treatment of hypoglycemia is common in urban emergency medical services (EMS) systems. The rate of relapse is unknown. The goal of this study was to compare the outcomes of diabetic patients initially refusing transport (refusers) and those transported to an ED. Methods: All paramedic runs from January to July 1995 were retrospectively reviewed. Inclusion criteria were adult patients with a field assessment of hypoglycemic signs/symptoms, and a fingerstick glucose < 80 mg/dL. Data for analysis included paramedic run duration, patient demographics, and refusal or acceptance of transport. Patient outcome was obtained from a review of hospital and medical examiner records. Relapse was defined as hypoglycemia necessitating EMS activation or an ED visit within 48 hours of the initial episode. Student's t‐test and x2 analysis were used to compare means and rates, respectively. Results: Over the 7 months, 374 patients made 571 calls to 9‐1‐1 that met inclusion criteria (5.2% of all paramedic runs). Of these, 412 were refusers (72.2%) and 159 were transported patients (27.8%). The hospital records of 4 transported patients were unavailable. Sixty‐three transported patients were admitted (11.2%), with 1 death from prolonged hypoglycemia. The rates of relapse did not differ between the refusers and the transported patients (p < 0.05). Twenty‐five relapses occurred among the refusers (6.1%), with 14 repeat refusals, 11 transports, 5 admissions, and no deaths. There were 7 relapses among the transported patients (4.4%), with 2 refusals, 5 transports, 2 admissions, and no deaths. The paramedic run time was significantly shorter for the refusers than for the transported patients (p < 0.05). Conclusions: The out‐of‐hospital treatment of hypoglycemic diabetic patients appears to be effective and efficient. Independent of the patient's refusal or acceptance of transport, the out‐of‐hospital treatment of hypoglycemic patients in this system appears to be safe.
