Critical Illness-Related Corticosteroid Insufficiency (CIRCI) among Patients with Refractory Shock at a Tertiary Hospital: A Look into Clinical Practices and Patient Outcomes

Abstract

Introduction. A significant number of critically ill patients, as high as 60% among patients with septic shock, suffer from critical illness-related corticosteroid insufficiency (CIRCI), which refers to an inadequate corticosteroid response to the level of stress.
 Objectives. This study aimed to determine the strategies employed in managing patients with critical illness-related corticosteroid insufficiency and the outcomes of these patients at a tertiary hospital.
 Methods. This was a single-center, mixed-methods study which consisted of a review of charts of patients 19 years old and above admitted for shock or developed refractory hypotension from January 2017-December 2019, and key informant interviews and focus group discussion among clinicians who have experience in managing CIRCI.
 Results. A total number of 362 patient charts reviewed showed a relatively low rate of initiation of corticosteroids for patients with refractory shock, at just 28.57% of the entire population. After corticosteroids were initiated, patients were in shock for a median of just one day and the median blood pressure improved to 100/60 mm Hg. In this cohort, patients who were started on steroids had more severe illness, as measured by the Mortality Probability Model (MPM) score, which had a median of 43.65% for the group on steroids and just 25.0% for the non-steroid group (p ≤ 0.0001). Patients who were started on steroids had a statistically significant longer median days on a ventilator, 5 days vs. 3 days for the non-steroid group (p = 0.0297); longer median length of intensive care unit (ICU) stay, 8 days vs. 5 days for the non-steroid group (p = 0.0410), and a higher morbidity and mortality rate. The need for steroids, the presence of septic shock, and a higher MPM score were significant predictors of mortality.
 Discussions among clinicians revealed significant variability in practices in the management of CIRCI.
 Conclusion. The presence of clinical features of CIRCI is a poor prognostic factor. Timely recognition, work-up, and interventions to address CIRCI are paramount in critical care.
