Health care providers use a variety of computerized medical information sources to reduce knowledge gaps and support patient care decisions. Few studies have evaluated the impact of medical information sources on patient outcomes. Skin problems are the reason for many visits to primary care providers and result in a high percentage of referrals to dermatologists and return visits to primary care for the same skin problem.
The objective is to evaluate the impact of primary care providers' use of a dermatology information source, VisualDx, on skin problems outcomes.
The study design is a cluster-randomized controlled trial. Participants include primary care providers as clusters and their patients with skin problems. Providers are randomized to intervention group that refers to VisualDx when seeing a patient with a skin problem, or to the control group who does not. Patients have the randomized group status of the doctor they saw for the problem.
Patients are interviewed to determine the problem status and how many follow-up visits they had for the problem at intervals after the index visit.

Experimental: Intervention - VisualDx Arm
Arm had 2 levels: provider (cluster) level and patient level. Providers, randomly assigned to the intervention arm, refer to VisualDx when they saw a patient who presented with a skin problem. Their patients were assigned to the intervention group and interviewed about the outcomes of their treatment.
VisualDx is a computerized clinical information technology with medical image and text content in dermatology.
No Intervention: Control - Usual Care Arm
Arm had 2 levels: provider (cluster) level and patient level. Providers, randomly assigned to control, did not refer to VisualDx but could refer to other information sources or none per usual care. Their patients were assigned to the control group and interviewed about the outcomes of their treatment
- Number of Patients With Resolved Skin Problems [ Time Frame: Period of assessment was up to 3 months (90 days) after index visit. ]Resolved skin disease status was assessed by phone interview. Patient reported status. Patients were censored if "unresolved" at 90 days.
- Number of Follow-Up Visits to Any Provider for the Same Problem [ Time Frame: Period of Assessment is up to 90 days after index visit ]Follow-up visits count is assessed at each phone interview. Patients report return visits.
