Background:
There is a need to determine the difference in response to mail, e-mail, and phone in clinical research surveys.
Methods:
We enrolled 150 new and follow-up patients presenting to our hand and upper extremity department. Patients were assigned to complete a survey by mail, e-mail, or phone 3 months after enrollment, altering the follow-up method every 5 patients, until we had 3 groups of 50 patients. At initial enrollment and at 3 month follow-up (range 2-5 months), patients completed the short version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), the short version of the Patient Health Questionnaire (PHQ-2), the Pain Self-Efficacy Questionnaire (PSEQ), and rated their pain intensity.
Results:
The percent of patients that completed the survey was 34 % for mail, 24 % for e-mail, and 80 % for phone. Factors associated with responding to the survey were older age, nonsmoking, and lower pain intensity. Working full-time was associated with not responding.
Conclusions:
The response rate to survey by phone is significantly higher than by mail or e-mail. Younger age, smoking, higher pain intensity, and working full-time are associated with not responding.
Type Of Study/Level Of Evidence:
Prognostic I.
