研究目的
The purpose of the study is to extend research on patient satisfaction with telemedicine services by employing the theoretical framework of Expectation Disconfirmation Theory (EDT) for diabetic retinopathy screenings focusing on rural patients.
研究成果
The EDT model is a viable framework to study patient satisfaction of telemedicine services. Patients were highly satisfied with telemedicine and developed a favorable disposition towards telemedicine services. The study demonstrates the viability of telemedicine for diabetic retinopathy screenings in rural areas.
研究不足
The study is limited by the use of single-item measures for variables, the lack of a control group of patients who underwent diagnosis and treatment in a face-to-face context, and the focus on a single cross-section of patients attending a rural family practice office in the Midwest of the US.
1：Experimental Design and Method Selection:
The study employed a longitudinal field study design to assess patient satisfaction with telemedicine for diabetic retinopathy screenings using the EDT framework.
2：Sample Selection and Data Sources:
Adult subjects (n=220) with diabetes were recruited from a single family practice office in rural Iowa. Subjects completed a “pre” survey prior to using telemedicine and a “post” survey after receiving recommendations from distant ophthalmologists.
3：List of Experimental Equipment and Materials:
Digital retinal images were captured using a Topcon NW-200 “nonmydriatic” digital fundus camera.
4：Experimental Procedures and Operational Workflow:
Subjects were photographed by a nurse, and digital retinal images were reviewed by retina fellowship-trained ophthalmologists at the University of Iowa.
5：Data Analysis Methods:
Structural equation modeling (SEM) utilizing the partial least squares (PLS) method was used to test the hypotheses.
