Prehospital management of acute Addison Disease: Audit of patients attending a referral hospital in a regional area

Abstract

Context: Adrenal crisis (AC) causes morbidity and mortality in patients with Addison disease[primary adrenal insufficiency (PAI)]. Patient-initiated stress dosing (oral or parenteral hydrocortisone) is recommended to avert ACs. Although these should be effective, the continued incidence of ACs remains largely unexplained.

Methods: Audit of all attendances between 2000 and 2017 of adult patients with treated PAI to one large regional referral center in New South Wales, Australia. Measurements were those taken on arrival at hospital.

Results: There were 252 attendances by 56 patients with treated PAI during the study period. Women comprised 60.7% (n 5 34) of the patients. The mean age of attendees was 53.7 (19.6) years. Nearly half (45.2%, n 5 114) of the patients had an infection. There were 61 (24.2%) ACs diagnosed by the treating clinician. Only 17.9% (n 5 45) of the hospital presentations followed any form of stress dosing. IM hydrocortisone was used prior to presentation 7 (2.8%) attendances only. Among patients with a clinician-diagnosed AC, only 32.8% (n 5 20) had used stress dosing before presentation. Vomiting was reported by 47.6% (n 5 120) of the patients but only 33 (27.5%) of these attempted stress dosing and 5 patients with vomiting used IM hydrocortisone. The numberof prior presentations was an independent predictor of use of stress doses [1.05 (1.01, 1.09)]. Conclusion: Dose-escalation strategies are not used universally or correctly by unwell patients with PAI; many patients do not use IM or subcutaneous hydrocortisone injections. Previous hospital treatment increases the likelihood of stress dosing, and hospital attendance offers the opportunity for reinforcement of prevention strategies.
