according to an analysis of the 2012-2017 National Inpatient Sample (NIS).
The findings are consistent with prior studies implicating earlier and more severe disease in Black and Hispanic patients, and reinforce the importance of accurate diagnosis and early treatment.
Dermatologists should maintain “a higher index of suspicion for MF in patients with skin of color, as early diagnosis may help mitigate the downstream costs of management,” Justin Choi, BA, a medical student at the University of Illinois at Chicago, said at the annual Skin of Color Society symposium.
Mr. Choi and coinvestigators, led by Shawn Kwatra, MD, of Johns Hopkins University, Baltimore, identified hospital admissions for MF in the NIS for 10,790 White patients, 4,020 Black patients, and 1,615 Hispanic patients over the 5-year period. The inpatient prevalence of MF – the most common variant of primary cutaneous T-cell lymphoma – was highest in these groups.
Black and Hispanic patients who were hospitalized for MF were significantly younger than White patients, with a mean age of 51.7 years and 48.5 years, respectively, compared with 59.9 years (P < .001 in each case). They also had longer lengths of stay: 8.34 days on average for Black patients and 8.88 for Hispanic patients, compared with 6.66 days for White patients (P < .001 and P = .001, respectively).
Hispanic patients accrued the highest costs of care (a mean of $107,242 vs. $64,049, P =.003) and underwent more procedures (a mean of 2.43 vs. 1.93, P = .004) than White patients. Black patients similarly had higher costs associated with their hospital stay (a mean of $75,053 vs. $64,049, P =.042).
In a multivariate linear regression adjusted for age, sex and insurance type, Black race remained significantly associated with a longer LOS than White race, and Hispanic ethnicity with a longer LOS, increased costs, and more procedures than White race.
The NIS is a publicly available, all-payer inpatient care database developed for the Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project.
