Computerized adaptive resting with the I-HaND scale for monitoring patients with upper limb nerve pathology.

The Impact of Hand Nerve Disorders scale is a patient-reported outcome measure for upper limb nerve pathology. We aimed to assess its structural validity using item response theory and to develop computerized adaptive testing algorithms. We conducted a series of psychometric studies to assess constructs measured, applied an item response theory model to the data, then developed computerized adaptive testing algorithms.

Development and validation of a new patient-reported outcome measure for peripheral nerve disorders of the hand, the I-HaND© Scale.

Following guidelines from the Patient-Centred Outcomes Research Institute and using a mixed methods study, a new patient-reported outcome measure (PROM) for both nerve trauma and compression affecting the hand, the Impact of a Hand Nerve Disorders (I-HaND) Scale, was developed. Face-to-face interviews with 14 patients and subsequent pilot-testing with 61 patients resulted in the development of the 32-item PROM. A longitudinal validation study with 82 patients assessed the psychometric properties of the I-HaND.

Study Design: Grounded theory.

Introduction: The broader perspective of health offered by the World Health Organization's International Classification of Functioning, Disability and Health has had a significant bearing on how we view the measurement of health outcomes after surgical or therapy interventions for peripheral nerve disorders affecting the hand. The value of the patient's perspective is now recognized and outcomes which reflect this are being advocated in the clinical management and support of this population.
