Objectives: Longitudinal studies are often challenging to implement because of financial constraints, time demands on the investigators, and high attrition rates of study participants. Our objective is to describe the approach used to capture Patient-Reported Outcomes (PROs) and minimize study attrition during the Management of Dentin Hypersensitivity study in the National Dental Practice-Based Research Network (

Methods: This was a prospective, multicenter cohort study of patients with dentin hypersensitivity (DH) conducted in the network. PROs were assessed based on patients’ perceptions of pain using Visual Analog Scales and Labeled Magnitude scales at baseline and at 1, 4, and 8 weeks post-baseline. A total of 1,862 patients formed the study population.

Results: Eighty-five percent of study patients chose to complete follow-up assessments via an electronic mode; the remaining 15% completed them via a paper mode. Certain characteristics (age, education level, network region) of these two patient groups were significantly different. The overall retention rate of study patients was 92% at the 8-week assessment. Based on a mixed-effects logistic regression model, there was no significant difference in the proportion of patients who completed the 8-week assessment, comparing those who completed the study using the electronic mode to those who completed the study using the paper mode (p-value=0.34).

Conclusions: The electronic mode of data capture was as effective as the traditional paper mode method, while also providing the advantage of eliminating data entry errors, not involving site research coordinators in measuring the PROs, and not incurring cost and potential delays associated with mailing study forms.
