Introduction: Hidradenitis suppurativa (HS) is associated with a significant disease burden. The use of high-cost settings care are common among HS patients.
Objective: To explore factors that may influence hospital admissions and readmissions among HS patients.
Methods: Using ICD-9/10 codes (705.83 and L73.2), we extracted the medical records of adult HS patients who visited the Henry Ford Health System (HFHS) ED between 2010 and 2020.
Results: Of the 100 HS patients, 52 (52%) were admitted to an inpatient service. Hypertension (OR:2.55,95% CI:1.11-5.83, p value=0.027), diabetes mellitus (OR:2.42, 95%CI:1.05-5.61, p value =0.039), cellulitis (OR: 19.28, 95%CI:4.23-87.96 p<0.001), sepsis (OR:10.25, 95%CI:1.34-89.24, p value=0.025), and depression (OR:3.32, 95%CI:1.10-10.04, p value =0.002) were significant predictors of admission. Chronic kidney disease (OR:3.05, 95% CI:1.00-9.23,p value=0.049), congestive heart failure (OR:4.06, 95%CI:1.19-13.80, p value =0.025), coronary artery disease (OR:15.20, 95%CI:2.80-82.65, p value=0.002), chronic obstructive pulmonary disease (OR:8.94, 95%: 1.51-52.86, p value =0.003), cellulitis (OR:4.62, 95%CI:1.66-12.88, p=0.003), sepsis (OR:3.75, 95%CI:1.02-13.82,p value =0.047), and depression (OR:4.50, 95%CI:1.54-13.18, p value=0.006) were positively associated with readmission. Those who received outpatient dermatology care had a lower risk of being admitted (n=87, 28.7% vs n=13,100%, p <0.001) and readmitted (n=10, 11.5% vs n=5, 38.5%, p value =0.0108).
Discussion: In this study, we demonstrate that certain comorbidities, that are common among HS patients, are significant determinants of admission to an inpatient service. Furthermore, the increase access to outpatient dermatology care significantly reduces the likelihood of HS patients being admitted and readmitted.
Conclusion: The findings of this study illuminate the pivotal role of dermatologists in improving patients’ health outcomes while minimizing the avoidable use of high-cost settings care.
