Details and patient eligibility

About

The purpose of this study is to evaluate the process, accuracy and patient outcomes of pre-screening dermatology referrals in a clinical setting by a qualified nurse. The long-range goal of the proposed program is to improve referral wait times for patients to see a dermatologist for lesions suspicious for melanoma in comparison to normal standards of care in NS. If effective, this screening program would decrease wait times for those patients with lesions suspicious for melanoma providing earlier diagnosis and expedited treatment, and potentially reducing mortality rates.

Full description

The purpose of this study is to evaluate the process, accuracy and patient outcomes of pre-screening dermatology referrals in a clinical setting by a qualified nurse using a dermatoscope, triaging suspicious lesions vs. benign lesions. The long-range goal of the proposed program is to improve referral wait times for patients to see a dermatologist for lesions suspicious for melanoma in comparison to normal standards of care in NS. If effective, this screening program would decrease wait times for those patients with lesions suspicious for melanoma providing earlier diagnosis and expedited treatment, and potentially reducing mortality rates.

Trial design

121 participants in 2 patient groups

Group 1 Control group

Description:

Patients randomized into this group will follow normal standard of care in Nova Scotia

Group 2 Active group

Demographic data: gender, date of birth, ethnicity 3. Health history (duration of lesion, changes in lesion, specific changes, who identified the lesion, measurement in two greatest dimensions radially and color.
