The utility of a data-logging device for measuring adherence to home phototherapy.
BACKGROUND
Treatment adherence to home phototherapy is not well characterized.


OBJECTIVE
To develop an accurate measure of home phototherapy unit usage.


METHODS
We tested a commercially available data logger containing a photo-sensor on two home phototherapy units.


RESULTS
The data logger accurately recorded actual usage and did not record stray light sources over the study period.


CONCLUSIONS
A data logger can accurately capture usage patterns for a home phototherapy unit. These devices could potentially be used in clinical trials to measure adherence to home phototherapy treatment regimens.
