A method is provided for automatically determining the status of a wearable sensor device configured to be worn by a user. The wearable sensor device includes at least one accelerometer that generates device acceleration data indicating an acceleration of the sensor device. The device acceleration data is used for both (a) a sensor device attachment analysis and (b) a turn protocol compliance analysis. The sensor device attachment analysis includes comparing the device acceleration data to stored reference data, determining an attachment or position status of the sensor device with respect to the user based on the comparison, and generating a corresponding alert notification. The turn protocol compliance analysis includes monitoring an orientation of the user based on the device acceleration data, comparing the monitored user orientation to at least one turn parameter defined by a turn protocol, and generating a turn protocol alert notification based on the comparison.
