EVALUATION OF AN ADAPTIVE PATIENT DATA ENTRY INTERFACE

Clinical data collected from patients is critical to delivering medical
care, monitoring care quality and tracking care outcomes. Data collection by
clinicians is costly and time consuming. Automated systems based on
questionnaires have been used to collect clinical information directly from
patients; such systems have an advantage over paper-based modalities because
they capture patient data in an electronic format that can be readily analyzed.
These systems, however, have not been widely used because of high costs and
failure to accommodate the diverse literacy and computer skills of individual
patients. The goal of this project is to revolutionize automated data
collection from patients by adapting both the questionnaire content and the
content-presentation/response-entry interface to fit the skills of the patient.
In the first half of this 3 year project, three parallel development efforts
will create the Adaptive User Interface System (AUIS): Aim I will create a
generalized, Web-based program for assessing patient aptitudes in a clinical
setting; Aim 2 will define a generalized approach for developing sets of
multimedia interfaces customized to user skill categories that will be used to
create the presentation of a health maintenance/risk assessment (HM/RA)
questionnaire; Aim 3 will develop the Web-based AUIS to present questionnaires
through adapted user interfaces by modifying the interface presentations of an
existing questionnaire-presenting system (created by this research team) to
incorporate the patient assessment program and the customized multimedia
interface sets developed in Aims 1 and 2, respectively. Finally (Aim 4), this
project will test the hypotheses that a questionnaire presented using the AUIS
will collect clinical data with greater completeness, higher quality, more
efficiency and lower cost than traditional, paper-based methods. Specifically,
completion of a HM/RA questionnaire will be evaluated in a randomized,
crossover controlled trial comparing the paper-based questionnaire data
collection method with an automated, Webbased questionnaire presented through
an adaptive user interface. The trial will be performed at two primary care
clinics representing diverse patient populations. The interface will be adapted
primarily on patient native languaguage (English or Spanish) and literacy and
secondarily on patient computer skills and familiarity with medical
terminology. If proven effective, the AUIS will introduce a novel approach for
enhancing, data quality and lowering data collection costs. The AUIS can be
widely disseminated at relatively low cost because of its Web-based,
generalized design and its utility across diverse patient populations.
The research team is fully qualified to conduct all aspects of the
proposed project because of its past work developing a Webbased, interactive
clinical guideline server; refining literacy assessment tools; creating
tailored patient data collection systems; and evaluating decision support
systems in clinical practice.
