Adding Value to the Care of Hospitalized Patients

Following other inpatient models, hospitalist dermatology has begun to demonstrate feasibility, advances in quality improvement, and most importantly improved health care outcomes. In an effort to better characterize the enhancement of such health care delivery, recent literature around the impact of inpatient dermatology consultation has centered on improving key objective hospital-based quality measures, namely diagnosis and management as well as hospital length of stay (LOS) and readmission rates.5,12-18

When identifying cutaneous disease, recent evidence points to the increased diagnostic accuracy by way of dermatology consultation. Specifically, diagnoses were changed 30% to 70% of the time when consultations were provided.6,12-15 Interestingly, misdiagnosis regularly centered on common diagnoses, specifically cellulitis, stasis dermatitis, and hypersensitivity reactions.6,12-16 In a multi-institutional retrospective study that examined the national incidence of cellulitis misdiagnosis, the authors found that when a dermatology consultation for presumed cellulitis was called, approximately 75% (N=55) of cases represented mimickers of cellulitis, such as stasis dermatitis, contact dermatitis, and cutaneous fungal infections. Moreover, in more than 38% (N=21) of such cellulitis consultations, patients often had more than one ongoing disease process, further speaking to the diagnostic accuracy obtained from expert consultation.16 The result of such misdiagnosis is not trivial, as unnecessary hospital admission or inappropriate treatment due to misdiagnosis of cutaneous disease often leads to avoidable complications and preventable health care spending. In a cross-sectional analysis of patients diagnosed with presumed lower extremity cellulitis (N=259), approximately 30% were misdiagnosed. In these cases, more than 90% of patients received unnecessary antibiotics, with approximately 30% of them experiencing a complication or avoidable utilization of health care related to their misdiagnosis.17

Along with the profound impact on diagnostic accuracy, management and treatment are almost universally affected after dermatology consultation.5,12-14 Such findings bear importance on optimizing hospital LOS as well as readmission rates. For hospital LOS, a recent study demonstrated reductions in LOS by 2.64 days as well as 1-year cutaneous disease-specific readmissions for patients who received dermatologic consultation for their inflammatory skin disease.18 Similarly, in a recent prospective cohort study of patients diagnosed with presumed lower extremity cellulitis, hospital LOS decreased by 2 days following a diagnosis of pseudocellulitis via timely dermatologic consultation. Across the United States, such reductions in LOS associated with unnecessary hospitalization due to pseudocellulitis can result in annual health care savings of $100 to $200 million.13 As such, early dermatologic intervention plays a vital role in diagnostic accuracy, appropriate treatment implementation, expedited discharge, and the overall economics of health care delivery and utilization, thereby supporting the utility of clinical decision support through expert consultation.


There is a clear and distinct value that results in having specialized inpatient dermatology services. Such expert consultation enhances quality of care and reduces health care costs. Although the implementation and success of inpatient dermatology services has primarily been observed at large hospitals/tertiary care centers, there is incredible potential to further our impact through engagement in our community hospitals. With that said, all practicing dermatologists should feel empowered to employ their expert skillset in their own communities, as such access to care and specialty support is desperately needed and can remarkably impact health care outcomes. Moreover, in addition to the direct impact on health care delivery and economics, the intangible benefits of an inpatient dermatology presence are innumerable, as opportunities to promote quality research and improve trainee education also demonstrate our value. These facets together provide a positive perspective on the potential contribution that our field can have on shaping the outlook of hospital medicine. As such, in addition to enjoying the current renaissance of inpatient dermatology, it is imperative that dermatologists build on this momentum and invest in the future of consultative dermatology.
