Data-Driven Dermatology Improves Patient Outcomes

The use of realworld data and realworld evidence to inform health care decisions is increasing. While randomized controlled trials (RCTs) are still the gold standard for evidence-based medicine, the strict inclusion/exclusion criteria and tightly controlled conditions limit their generalizability to real-world clinical practice.  Real world evidence (RWE), generated during routine clinical practice, is becoming increasingly important in determining effectiveness outside of the tightly controlled conditions of RCTs, and is now recognized by regulatory bodies such as the US Food & Drug Administration (FDA) and European Medicines Agency (EMA) as a valuable complement to RCTs.1

Real world data (RWD) is collected in routine clinical practice and can be gathered prospectively or retrospectively via a range of studies including prospective and retrospective observational studies, patient registries and post-marketing studies.

Real world evidence (RWE) is the clinical evidence about the usage and potential benefits or risks of a medical product derived from analysis of RWD.

Realworld evidence and observational studies help to bridge the gap in knowledge that exists between clinical trials and clinical practice. Compared with RCTs, RWE better reflects the actual clinical environments in which medical interventions are used, including patient demographics, comorbidities, adherence, and concurrent treatments.3

Real World Evidence Corroborates Colloidal Oatmeal Efficacy for AD

Atopic dermatitis (AD) is a common, relapsing inflammatory skin disease with pruritus, characterized by recurrent exacerbations and remissions.4 AD impairs patients’ quality of life and places a heavy burden on patients.5

The efficacy and safety of colloidal oatmeal formulations for the treatment of children and adults with mild to moderate atopic dermatitis is well established, proven to reduce itch severity and improve quality of life in clinical trials.6-8

In fact, colloidal oatmeal is the only single skin protectant OTC active ingredient that can claim to temporarily protect and help relieve symptoms of eczema as recognized by the US FDA & Health Canada OTC Monographs.9,10

Retrospective study shows using emollients for AD results in fewer primary care visits and reduced healthcare utilization11

This is the first comprehensive study to show the impact emollients, and specifically AVEENO® can have over other emollients when used as first-line therapy for the treatment of AD.  Over 54,000 patients with chronic dry skin and eczema were identified using the UK Clinical Practice Research Datalink (CPRD) and their records were reviewed for the 2 years following first diagnosis.

AVEENO® Colloidal Oatmeal lotion reduced the need for prescription steroids and antimicrobials11

Patients using AVEENO® first over other emollients were at least 21% less likely to receive a prescription for a potent or very potent topical corticosteroid or an antimicrobial within 2 years after diagnosis. This supports previous research suggesting emollient use can reduce the need for a TCS prescription12-15 Timely prescribing of AVEENO® to improve the integrity of the skin barrier can also result in fewer flares.16-17

This study used real world evidence from children and adults with chronic dry skin and eczema to confirm that the use of emollients results in fewer primary care visits, reduced healthcare utilization and reduced costs in the treatment of AD.
