Canadian Humira Post Marketing Observational Epidemiological Study: Assessing Effectiveness in Psoriasis

PGA≤1: Percentage of Participants at Month 12

The PGA is an assessment by the investigator of the overall disease severity at the time of evaluation. The PGA uses a 6-point scale. The degree of overall lesion severity was evaluated using the following categories: * 0 (Clear): No evidence of scaling or plaque elevation; erythema may be present; * 1 (Minimal): scaling may be present, up to moderate erythema, minimal plaque elevation; * 2 (Mild): Fine scaling, up to moderate erythema, slight plaque elevation; * 3 (Moderate): Coarse scale dominates, moderate erythema, moderate plaque elevation; * 4 (Severe): Coarse non-tenacious scale dominates, severe erythema, marked plaque elevation; * 5 (Very Severe): Very coarse thick tenacious scale predominates, very severe erythema, severe plaque elevation. A higher score indicates greater disease severity. Percentages based on the total number of ITT participants who attended each visit.

Psoriasis and Arthritis Screening Questionnaire (PASQ) Total Score: Change From Baseline to Month 3

PASQ is an 11-item tool that ascertains self-reported presence of joint pain and swelling by the participant. The PASQ questionnaire consists of 10 questions for which a positive and negative response are assigned a score of 1 or 2, and 0, respectively. The maximum score is 10. In addition, participants were also asked to indicate on a diagram where they experienced joint swelling or pain. The diagram was scored 0, 1, 3, or 5, depending on the distribution of the participants' markings. The final composite score for the PASQ ranges from 0 to a maximum of 15.

Body Surface Area of Psoriasis Involvement: Change From Baseline to Month 6

The Body Surface Area (BSA) is an indicator of disease severity and the affected area is expressed as a percentage of the total body surface area.The BSA affected by psoriasis was measured by the physician selecting the participant's right or left hand as the measuring device. For purposes of clinical estimation, the total surface of the palm plus 5 digits was to be assumed to be approximately equivalent to 1% BSA. Measurement of the total area of involvement by the physician was aided by imagining if scattered plaques were moved so that they were next to each other and then estimated the total area involved. A decrease in BSA affected by psoriasis indicates improvement.

Dermatology Quality of Life Index (DLQI) Total Score: Change From Baseline to Month 3

The Dermatology Quality of Life Index (DLQI) is a 10-question questionnaire that asks the participant to evaluate the degree that psoriasis has affected their quality of life in the last week and includes 6 domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment). Responses to each domain are not relevant (0), not at all (0), a little (1), a lot (2), and very much (3). The DLQI is calculated by summing the scores of the questions and ranges from 1 to 30, where 0-1 = no effect on participant's life, 2-5 = small effect, 6-10 = moderate effect, 11-20 = very large effect, and 21-30 = extremely large effect on participant's life. The higher the score, the more the participant's quality of life is impaired. A 5-point change from baseline is considered a clinically important difference.

Work Limitation Questionnaire (WLQ) Total Score: Change From Baseline to Month 6

The Work Limitation Questionnaire (WLQ) is a self-administered questionnaire comprised of 25 questions. The WLQ evaluates the participant's overall ability to work in the last two weeks. It comprises 25 questions each with a range of 100% ('all of the time') to 0% ('none of the time') where 6 represents non-applicability to the patient's line of work. The WLQ Productivity Loss Score indicates the percentage decrement in work output due to health problems. The WLQ Productivity Loss score is based on a weighted sum of the scores from the 4 WLQ scales (Time, Physical, Mental-Interpersonal, and Output). The resulting score (known as the WLQ Index) is in the form of the natural log of work productivity. The final step needed to generate the WLQ Productivity Loss Score is to convert the WLQ Index score to a percentage. The higher the score, the greater the work limitation.

WLQ Productivity Loss Score: Change From Baseline to Month 24

The WLQ is a self-administered questionnaire comprised of 25 questions. The WLQ evaluates the participant's overall ability to work in the last two weeks. It comprises 25 questions each with a range of 100% ('all of the time') to 0% ('none of the time') where 6 represents non-applicability to the patient's line of work. The WLQ Productivity Loss Score indicates the percentage decrement in work output due to health problems. The WLQ Productivity Loss score is based on a weighted sum of the scores from the 4 WLQ scales (Time, Physical, Mental-Interpersonal, and Output). The resulting score (known as the WLQ Index) is in the form of the natural log of work productivity. The final step needed to generate the WLQ Productivity Loss Score is to convert the WLQ Index score to a percentage. The higher the score, the greater the work limitation.
