Development and Evaluation of a Self-Assessment Tool for Psoriasis Severity

Psoriatic arthritis (PsA) is an inflammatory arthritis that develops in approximately 2.9% of patients with psoriasis each year1,2. Early prediction of which patients will develop PsA is crucial for a patient&#39;s quality of life as a diagnostic delay of as little as six months may cause irreversible damage to the joints3. A previous study had identified features associated with early-stage PsA. The three components of the Investigator&#39;s Global Assessment (IGA)-induration (thickness), erythema (redness), and desquamation (scaliness)-were highly correlated with each other and were nominally associated with subsequent PsA development. Multivariate analysis showed that a history of fingernail psoriasis and untreated induration of psoriasis lesions were independent PsA predictors4. Other studies have also identified psoriasis severity as associated with psoriatic arthritis2,5,6. The collection of these clinical factors is likely to be important in future PsA screening.
Several PsA screening tests exist7,8,9,10, but they require physicians to conduct them. A questionnaire-based screening test that can be completed by patients without physician assistance is an ideal format because it will not burden the dermatology and primary care clinics. Previously, the authors described a questionnaire with images that depict different severities of erythema and desquamation in multiple skin tones11. However, the measurement of induration requires a reference card corresponding to various plaque severities, such as that developed by the National Psoriasis Foundation12. The reference card is characterized by multiple raised areas of varying elevations, each corresponding to a number representing induration severity. To assess a patient&#39;s psoriasis severity in terms of induration, the card user compares the thickest psoriasis patch on a patient&#39;s body to the elevated areas on the card.
However, distributing a reference card to psoriasis patients may not be the most efficient approach for reaching a broad audience, especially for patients located outside the USA and for online survey studies. For researchers and clinicians gathering induration self-assessments from numerous patients, an alternative option could involve creating a homemade induration card using inexpensive office supplies. For patients, creating a homemade device from inexpensive office supplies can be more cost-effective than purchasing commercially available alternatives. This protocol describes how to create the Psoriasis Thickness Reference Card, an induration reference card that psoriasis patients can feel to assess the severity of their psoriasis induration. The Card can be made with standard office supplies and is inexpensive to make.

Psoriasis plaque severity metrics, such as induration (thickness), erythema (redness), and desquamation (scaliness), are associated with the subsequent development of psoriatic arthritis (PsA) among cutaneous-only psoriasis patients (patients with skin or nail psoriasis but no psoriatic arthritis). These metrics can be used for PsA screening. However, a key challenge in PsA screening is to optimize accessibility and minimize costs for patients, while also reducing the burden on healthcare systems. Therefore, an ideal screening tool consists of questions that patients can answer without a physician's assistance. Although reference images can be used to help a patient self-assess erythema and desquamation severity, a patient would need a tactile induration reference card to self-assess induration severity. This protocol describes how to create an induration reference card, the Psoriasis Thickness Reference Card, as well as how to use it to assess lesion induration severity. Administration of reference images for erythema and desquamation and a Psoriasis Thickness Reference Card for induration to 27 psoriasis patients showed that patients were moderately successful at self-assessing the severity of these three metrics. These findings support the feasibility of a future PsA screening test that patients can complete without the need for physician assistance.

This paper details the creation of a Psoriasis Thickness Reference Card, enabling psoriasis patients to self-assess their psoriasis plaque thickness without the need for physician assistance. Additionally, the precision of self-assessment for psoriasis redness and scaliness by employing reference images depicting various skin tones is assessed.
