Study summary

This validation study aims to develop a standardised investigator global assessment (IGA) score for keratosis pilaris and test the validity and reliability of the score through a one-day scoring exercise held at a private practice and compare it to a standard 0-4 IGA score specifically defined for keratosis pilaris.

Read the detailed description

This is a prospective validation study aiming to develop and validate a standardised IGA score for KP. Firstly, a preliminary score will be developed using deidentified photos of patients with KP. These photos will only be used to create the training slide for the assessors. The proposed score, Keratosis Pilaris Area Index (KPAI), is a 5-point IGA score (0-4) of five main body areas: face, upper limbs, lower limbs, trunk, and buttocks, for a maximum of 20 in two main categories, activity (erythema, skin roughness and papulation) and damage (pigmentation and scarring). The final score will be a maximum of 100. This will be compared to a standard 0-4 IGA score, defined specifically for KP, known as a KP-IGA.

The one-day scoring exercise has been modified from the Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI) validation (Loh et al., 2014). It will take place at Premier Specialists, Kogarah, Sydney with all co-investigators conducting the study in person at this single study site. Each dermatologist and medical professional involved will receive training on using the scores through a slideshow of training photos prior to the live scoring session. Five dermatologists and four medical professionals will be randomly assigned to assess 20 KP patients in 5-minute intervals, using the proposed scoring system, KPAI, and the KP-IGA score. This data will be used to assess inter-rater reliability.

Each dermatologist or medical professional will be randomly assigned to rescore two patients after seeing other patients to minimise recall bias. The randomisation will be done by an investigator who is uninvolved in the scoring session and has had no interaction with both patients and assessors. Data gathered from this section is used to determine intra-rater reliability.

Every participant will also complete two QOL questionnaires: the DLQI/CDLQI and HADS. This data will be used to provide insight of patient's subjective perceptions of KP and the psychological impact it may have on them.

Participants who attended the scoring day will be invited to attend a follow-up scoring session in September - October 2022. The purpose of this scoring session is to see how stable their condition is and take baseline photographs of their skin to monitor their condition.

Four assessors will score the participants in 5-minute intervals with the proposed scoring system KPAI and the KP-IGA. Participants will be offered free samples of Cerave Salicylic Acid Smoothing Cleanser and Cream to try. They will be invited to return for another rescoring in November - December 2022 to see if there is any improvement in their KP and if the score is responsive to change.

In the November - December 2022 scoring session, participants will be given free samples of Propaira 30% Urea exfoliating emollient and Propaira 20% Lactic acid exfoliating lotion to try. They will be invited to return for a fourth scoring session in December to monitor their progress and see if the scores improve.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Keratosis Pilaris Area Index (KPAI)

    This study aims to develop and validate an IGA score for evaluating KP (KPAI) by determining the intra-rater and inter-rater reliability through testing the composite IGA score on patients and comparing it to a standard 0-4 IGA that will be defined specifically for KP.

    Time frame: through study completion, an average of 1 year

Secondary outcomes

  1. QOL questionnaires (DLQI/CDLQI)

    The secondary aim of the study is to explore the impact KP may have on patients' QOL by using the (Child) Dermatology Life Quality (DLQI/CDLQI) Index questionnaires.

    Time frame: through study completion, an average of 1 year

  2. QOL questionnaires (HADS)

    The secondary aim of the study is to explore the impact KP may have on patients' QOL by using the hospital anxiety and depression scale (HADS) questionnaires.

    Time frame: through study completion, an average of 1 year
