Streamlining Psoriatic Arthritis Screening and Management Using the IDEOM Clinical Framework: A Quality Improvement
This quality improvement initiative improved psoriatic arthritis (PsA) screening and assessment in dermatology clinics. The framework facilitated timely rheumatology referrals, leading to a higher rate of PsA diagnosis and better patient management.
Area of Science:
- Dermatology and Rheumatology
- Clinical Quality Improvement
- Patient Outcomes
Background:
- Psoriatic arthritis (PsA) is frequently undiagnosed, leading to irreversible joint damage.
- Early screening and assessment are crucial for timely intervention and improved patient outcomes.
- A quality improvement initiative was implemented to enhance PsA detection and management in dermatology settings.
Purpose of the Study:
- To evaluate the feasibility and effectiveness of a clinical framework for PsA screening and assessment.
- To integrate validated screening tools into routine dermatology practice.
- To improve the rate of rheumatology referrals and subsequent diagnosis for patients with PsA.
Main Methods:
- Implementation of the Psoriasis Epidemiology Screening Tool (PEST) and Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire into electronic medical records across 26 dermatology clinics.
- PsA screening for Psoriasis (PsO) patients using PEST, with positive screens or existing PsA diagnoses proceeding to PsAID-12 completion.
- Utilizing PsAID-12 scores to guide management decisions, including treatment adjustments and rheumatology referrals for scores exceeding a defined threshold.
Main Results:
- Over 27 months, 37.2% of eligible PsO patients completed the PEST, with 12.5% scoring ≥3 and completing the PsAID-12.
- 75.7% of patients completing the PsAID-12 had scores ≤4, indicating effective disease management.
- Among patients scoring >4 on the PsAID-12, 24.7% were referred to rheumatology, and 44.4% received a subsequent PsA diagnosis. A significant reduction in average PsAID-12 scores was observed in patients assessed twice.
Conclusions:
- The integrated clinical framework is feasible for optimizing PsA screening and assessment in dermatology settings.
- The initiative demonstrated success in identifying undiagnosed PsA and facilitating appropriate rheumatology referrals.
- The study highlights the potential to improve the quality of care for patients with psoriasis and suspected psoriatic arthritis.
