Feasibility Of Post-Operative Mobile Health Monitoring Among Colorectal Surgery Patients, Tanya Kuper

Electronic Thesis and Dissertation Repository

Post-operative readmission following colorectal surgery is a common and costly occurrence. Remote health monitoring via mobile applications has the potential to reduce post-operative readmissions by early identification of complications. This intervention depends on patient acceptance and compliance with available technology. The feasibility of home monitoring using automated daily surveys and wound photo uploads, delivered via a mobile health application, was tested in the immediate post-operative period after colorectal surgery. Patient compliance, the association between generated alerts and readmissions, and patient satisfaction were measured. Patient satisfaction was high; 80.5% of patients reported that they felt safer going home knowing that they …

Voice Analysis With Iphones: A Low Cost Experimental Solution, Benjamin Van Der Woerd

Electronic Thesis and Dissertation Repository

Background:

Acoustic voice analysis requires a resource intensive setup, including a soundproof booth. This project evaluates smartphone microphone and recording environment impacts on voice sample collection for acoustic voice analysis. A proprietary analysis algorithm is presented for validation.

Methods:

Microphone and recording environment were evaluated using previously collected voice samples presented in four conditions to test two microphones and two recording environments. Prospective samples were used to test the proprietary algorithm, whereby samples were analyzed using this and Praat.

Results:

Microphone and recording environment had small, clinically unimportant impacts on most measurements. The proprietary algorithm reliably analyzed sustained vowels, with …
