Wireless patient monitoring compliance system
Methods and systems for close proximity monitoring of subjects, including in particular at-risk psychiatric subjects, where subjects have a tamper-resistant wearable device that signals an observer device, an observer records an observation of the subject, and the observer device emits an alert when the observer fails to record an observation during a predetermined time period.
1. A method of close-proximity monitoring of a subject, the method comprising:
transmitting a signal from a subject-worn beacon that is secured to a subject in a tamper-resistant manner that prevents the subject-worn beacon from being removed by the subject;
receiving the signal by an observer device worn by an observer;
prompting the observer to record a subject observation at an interval of not more than 20 minutes or less; and
emitting one or more alerts from the observer device when one or more of: the received signal indicates that the observer device is further than a predetermined range from the subject; and the observer does not record a subject observation within a predetermined observation time.
2. The method of claim 1 , further comprising determining a proximity between the subject and the observer from the signal.
3. The method of claim 1 , wherein the signal strength of the received signal is used to determine if the observer device is further than a predetermined range from the subject.
4. The method of claim 1 , wherein prompting the observer comprises prompting the observer at a random time interval of between 1 minute and 20 minutes.
5. The method of claim 1 , wherein prompting the observer comprises prompting the observer at an interval of 15 minutes or less.
6. The method of claim 1 , further comprising confirming that the observer is awake and wherein emitting one or more alerts from the observer device further comprising emitting the one or more alerts when the observer is not awake.
7. The method of claim 1 , further comprising confirming that the observer is awake based on an activity level measured from the observer device and wherein emitting one or more alerts from the observer device further comprising emitting the one or more alerts when the observer is not awake.
8. The method of claim 1 wherein the predetermined range is 10 feet or greater.
9. The method of claim 1 , wherein emitting one or more alerts from the observer device comprises emitting one or more alerts from the observer device when one or more of: the observer is further than a predetermined range from the subject for greater than a predetermined time interval.
10. The method of claim 1 , further comprising transmitting a report to a supervisor if the observer does not comply with the one or more alerts within a compliance time period.
11. The method of claim 10 , wherein the compliance time period is 1 minutes or more.
12. The method of claim 1 , wherein emitting one or more alerts from the observer device comprises emitting one or more of: an audible alert, a tactile alert, and a visual alert.
13. The method of claim 1 , wherein the signal is transmitted from the subject-worn beacon with a periodic frequency 0.01 Hz or greater.
14. The method of claim 1 , wherein the signal is continuously transmitted from the subject-worn beacon.
15. A method of close-proximity monitoring of a subject, the method comprising:
transmitting a signal from a subject-worn beacon that is secured to a subject so that it cannot be removed by the subject;
receiving the signal by an observer device worn by an observer;
determining a proximity between the subject and the observer from the signal;
prompting the observer, at an interval of 20 minutes or less, to record a subject observation in the observer device;
monitoring movement of the observer device; and
emitting one or more alerts from the observer device when one or more of: the observer is further than 10 feet from the subject for greater than a predetermined time interval; the observer device is moved less than a threshold level; and the observer does not record a subject observation within a predetermined observation time.
16. The method of claim 15 , wherein prompting the observer comprises prompting the observer at a random time interval of between 1 minute and 15 minutes.
17. The method of claim 15 , wherein prompting the observer comprises prompting the observer at an interval of 10 minutes or less.
18. The method of claim 15 , wherein the predetermined time interval is 30 seconds or more.
19. The method of claim 15 , further comprising transmitting a report to a supervisor if the observer does not comply with the one or more alerts within a compliance time period.
20. The method of claim 19 , wherein the compliance time period is 1 minutes or more.
