To describe the first 30 days of rapid adolescent telehealth scale-up in response to the coronavirus (COVID-19) pandemic at a single academic medical center and assess for disparities in visit completion rates by patient characteristics. Methods: Visit outcome and patient demographic data were obtained via electronic health record (EHR) reports. Telehealth visit completion rates were compared by patient characteristics using the chi-square test and t-test. We used zip code data to generate latitude-and longitude-based maps of the range and density of service delivery. Patient cases highlighting challenges and opportunities for adolescent telehealth were summarized. Results: Between March 16 and April 15, 2020, 392 telehealth visits were scheduled in 331 unique patients, with an 82% appointment completion rate. Video visits were conducted for eating disorders (39%), contraception/menstrual disorders (22%), gender-affirming care (17%), general adolescent medicine (15%), HIV treatment (6%), and substance abuse (1%). The majority of telehealth patients were female Caucasian minors with private insurance. There were no significant differences in telehealth visit completion rates by age, sex, gender, or insurance. Patients coded as non-white (African-American, Asian, or other) in the EHR had lower visit completion rates than white patients (p ¼ .003). Telehealth patients were distributed across five states, with the highest concentration in the zip codes nearest to the clinic. Conclusions: Rapid scale-up of telehealth for Adolescent Medicine was achieved at this large academic medical center. Future implementation research is needed to assure telehealth reaches adolescents without widening health disparities.

Central centrifugal cicatricial alopecia (CCCA) is a common cause of hair loss among patients of African and/or Caribbean descent, and there is little data exploring the quality of life of patients with this condition. This pilot demonstrates that CCCA has a significant impact on overall quality of life, and patients may benefit from resources to address psychosocial aspects of this diagnosis.

RATIONALE: As pain can exacerbate asthma, we hypothesize that people with back pain and asthma experience exacerbation of asthma during flare of back pain. Men and women equally suffer from back pain. Whether sex and age influence the co-occurrence of asthma and back pain has not been determined. METHODS: A cross sectional data analysis was performed using secondary data of adults (n520,588) treated at Kings County Hospital Center (inpatient, Emergency Department, Ambulatory Surgery) between Oct 2015 and March 2017 with ICD 10 code for back pain (M54.) and/or asthma (J45.). Logistic regression was used to determine likelihood of presentation. RESULTS:The mean age of the study population was 46 yrs 6 15 while the median age was 47 years. Females made up 12,189 (59%) of the study sample and males 8, 399 (41%). The occurrence of asthma with back pain was 404 (2%); of this, 274 (68%) were females and 130 (32%) were males (P <0.001). Age was not significantly associated with the co-occurrence of asthma and back pain. Males were 36% less likely to present with asthma and back pain when compared to females after adjusting for location of treatment and age (OR 0.64 (95% CI: 0.51 to 0.79), P<0.001. CONCLUSIONS: Females were more likely to present with a cooccurrence of asthma and back pain than males in acute care hospital settings. J ALLERGY CLIN IMMUNOL FEBRUARY 2019 AB224 Abstracts MONDAY
