The investigators propose to evaluate whether an innovative collaborative connected health (CCH) model increases access to specialists and improves patient outcomes. CCH offers multiple modalities for patients and primary care providers (PCPs) to access dermatologists online directly and asynchronously to maximize effectiveness in a real-world setting. CCH also fosters team care and patient engagement through active sharing of management plans and multidirectional, informed communication among patients, PCPs, and dermatologists. The specific aims of the proposal are to (1) determine whether the CCH model results in equivalent improvements in psoriasis disease severity compared to in-person care, (2) determine whether the CCH model results in equivalent improvements in quality of life and mental health compared to in-person care, and (3) assess whether the CCH model provides better access to care than in-person care.
The investigators propose to conduct a 12-month, pragmatic, randomized controlled trial to evaluate the impact of a collaborative connected health model for psoriasis management compared to inperson care. The pragmatic trial will compare psoriasis severity, quality-of-life, mental health, and access-to-care between the two models. We will enroll 300 psoriasis patients from Colorado and California. In addition to recruiting patients from the general population, we will place a specific emphasis on recruiting psoriasis patients living in rural and underserved communities. We will also recruit from the full disease spectrum of mild, moderate, and severe psoriasis patients. We will use an intention-to-treat approach to analyze outcomes and perform longitudinal data analysis using repeated measures approach to identify potential differences in the trend over time between the two arms. To evaluate the utility of CCH for increasing access from patients' and clinicians' perspective, the study team will conduct key informant interviews and use qualitative analytical techniques with investigator triangulation and member checking to enhance the validity of the conclusions.

CCH is an asynchronous, secure online platform where patients can upload images of psoriasis lesions and submit assessments. Likewise, practitioners can request and/or initiate dermatology consultations, assume longitudinal care or communicate with patients directly.
In-person care is the control group because it is currently considered the standard of care in delivering dermatologic services. The intervention includes regular visits to a physician, and may include such treatments as ointments, steroids or UV therapy at the discretion of a physician. In-person care is the major healthcare-delivery model for managing chronic skin diseases and a realistic, primary option that patients face. The patients in the in-person arm can seek psoriasis care from PCPs or dermatologists, just as they would in the real world.

Improvement in Self-Administered Psoriasis Area and Severity Index (SA-PASI)
Participants are asked to complete self-administered Psoriasis Area and Severity Index (SA-PASI). SA-PASI combines the assessment of lesion severity (erythema, induration, and scale) and the affected areas into a single score between 0 (no disease) to 72 (maximal disease). The primary outcome of the study was the mean percent improvement in SA-PASI averaged over three, six, nine, and 12 months. The percent improvement in SA-PASI was defined as the difference in SA-PASI scores between the baseline and each of the follow-up visits divided by the SA-PASI score from the baseline visit.
Time frame: 12 months
Improvement in Quality of Life as Measured by Dermatology-Specific, Quality of Life Instruments
Quality of life will be assessed using dermatology-specific, quality of life instruments, Skindex-16 and Dermatology Life Quality Index (DLQI). Scores for these assessments will be compared between patients randomized to the CCH model and in-person care. Skindex-16 is a validated and reliable instrument that comprehensively captures the effects of skin disease on health-related quality of life. It discriminates among patients with different effects and is responsive to clinical changes over time. Skindex-16 scores range from 0 (no effect) to 100 (effect experienced all the time), and the responses are aggregated in symptoms, emotions, and functioning subscales. The Dermatology Life Quality Index (DLQI) is another validated dermatology-specific quality-of-life instrument that has been used in many psoriasis trials. DLQI scores range from 0 to 30, with higher scores indicating more severe impact on quality of life.
Time frame: 12 months
Access to Care: Distance Traveled
Access to care is an overall term to capture the transportation to care factors including total distance traveled to see a provider (round-trip driving distance from patient's home to provider's office multiplied by the number of in-person visits during the study period).
Time frame: 12 months.
Depression Severity
Participants will be assessed for depression severity using the Patient Health Questionnaire (PHQ), a validated, self-administered diagnostic instrument for common mental disorders. The PHQ-9 score can range from 0 to 27 with 0 = "No" depression and 27 = "Severe" depression. The PHQ is a validated, self-administered version of the Primary Care Evaluation of Mental Disorders (PRIME-MD) diagnostic instrument for common mental disorders. The PHQ-9 is the depression module, which scores each of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) depression criteria as "0" (not at all) to "3" (nearly every day). A PHQ-9 score of 10 or greater has 89% sensitivity and 88% specificity for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. PHQ-9 is a validated tool for diagnosis of depression and monitoring response to interventions.
Time frame: 12 months
Other Psoriasis Disease Severity Measures
Body surface area (BSA) involvement and patient global assessment (PtGA) will be compared between the patients randomized to the CCH model and the in-person care. The BSA assessment is a well-established, validated measure used by psoriasis patients to report percent body surface affected by psoriasis in numerous prior studies. BSA ranges from 0% (no involvement) to 100% (complete body surface affected). The PtGA is a validated instrument that measures the overall psoriasis severity from the patients' perspective.40 PtGA is an ordinal six-point scale ranging from 0 (clear) to 5 (severe).
Time frame: 12 months
Access to Care: Wait Time
Access to care is an overall term to capture transportation factors including time taken to be seen by a provider. me. Wait time is measured by calculating roundtrip transportation time plus in-office waiting time multiplied by the number of in-person visits during the study period.
