Mortality and cause of death in patients with dermatologic diseases: An 11-year record-based observational study

Abstract

Background: Information on the cause of death is critical in guiding decisions on health infrastructure. However, there is a relative paucity of mortality data in patients with dermatologic diseases. Objectives: We aim to assess the overall mortality from dermatological disorders in a third-level university hospital which serves as a dermatology referral center. Methods: A retrospective medical note review of patients with dermatologic diseases who died during an 11-year period (from March 2008 to February 2020) was undertaken. Results: There were 63 death cases out of 2810 admissions for patients with dermatologic diseases (crude mortality 2.24%). The average age was 61.8 years and the male-to-female ratio was 2.3. Cutaneous malignancies (53.96%) were the primary causes of death, followed by drug reactions (23.8%). Among skin cancers, squamous cell carcinoma (SCC; 47.05%) and melanoma (35.29%) were the leading causes of death. Toxic epidermal necrolysis (53.33%) was the leading cause of death among drug reactions. Sepsis (30.74%) was the most common immediate cause of mortality in this series. A large fraction of patients (73%) had significant underlying comorbidities. Conclusion: The principal cause of mortality was cutaneous malignancies (mainly SCC and melanoma) followed by drug reactions. Sepsis was the most common immediate cause of death.
