Abstract

Importance: The value of inpatient dermatology consultations has traditionally been demonstrated with frequency in changes of diagnosis and management; however, the impact of dermatology consultations on metrics such as hospital length of stay and readmission rates remains unknown.

Objective: To determine the association of dermatology consultations with patient care in hospitalized patients using objective values.

Design, Setting, and Participants: We retrospectively queried the deidentified database of patients hospitalized between January 1, 2012, and December 31, 2014, at a single university medical center. A total of 413 patients with a primary inflammatory skin condition discharge diagnosis and 647 patients with primary inflammatory skin condition admission diagnosis were selected.

Main Outcomes and Measures: Hospital length of stay and 1-year readmission with inflammatory skin conditions.

Results: The 413 patients with a primary inflammatory skin condition discharge diagnosis were 61.0% female and had a mean (SD) age of 55.1 (16.4) years. The 647 patients with primary inflammatory skin condition admission diagnosis were 50.8% female and had a mean (SD) age of 57.8 (15.9) years. Multivariable modeling showed that dermatology consultations were associated with a reduction of 1-year inflammatory skin condition readmissions among patients who were discharged primarily with an inflammatory skin condition (readmission probability, 0.0025; 95% CI, 0.00020-0.030 with dermatology consult vs 0.026; 95% CI, 0.0065-0.10 without; odds ratio, 0.093; 95% CI, 0.010-0.840; P = .03). No other confounding variable was associated with reduction in readmissions. Multivariable modeling also showed that dermatology consultations were associated with a reduction in the adjusted hospital length of stay by 2.64 days (95% CI, 1.75-3.53 days; P < .001).

Conclusions and Relevance: Dermatology consultations were associated with improvements of outcomes among hospitalized patients. The expansion of the role of dermatology consultation services may improve patient care in a cost-effective manner.
