A prospective 52-week randomized controlled trial of patient-initiated care consultations for patients with psoriasis.

Abstract

Treatment and care of moderate-to-severe psoriasis require lifelong consultations with a dermatologist with close monitoring of systemic treatment. To investigate the effect of patient-initiated care consultation (PICC) for patients with psoriasis in a dermatology outpatient clinic. A prospective randomized controlled trial with patients on well-controlled systemic treatment randomized to either (i) the PICC group, where they participated in one annual consultation with a dermatologist but were able to initiate consultations when needed; or (ii) routine care, where they participated in a consultation every 12-16 weeks. The primary outcome was the Dermatology Life Quality Index (DLQI). Other outcomes were safety, patient adherence and satisfaction with healthcare assessed at baseline and after 52 weeks. The study was registered with clinical trials number NCT02382081. In total 150 patients were included, with 58·0% treated with biologics, 37·3% with methotrexate and 4·7% with acitretin. At week 52 no statistically significant mean difference between groups was detected in DLQI (0·28, 95% confidence interval -0·35 to 0·9) or Psoriasis Area and Severity Index (-0·24, 95% confidence interval -0·84 to 0·36). Patients in the PICC group requested 63% fewer consultations with a dermatologist: mean 2·5 ± 0·1 vs. 5·1 ± 0·6 (P = 0·001). Patient adherence and safety with treatment monitoring were equal between groups, but the PICC group was significantly better at attending consultations than the control group (P = 0·003). PICC offers additional clinical benefits over routine care, making patients less dependent on clinical visits. The intervention adds no harm to monitoring systemic treatment, and patients report high quality of life and satisfaction with healthcare.
