Initial investigation into the event identified that the patient submitted a 1.0 lb decrease from the previous day's measurement but the system triggered a weight increase flag.In reviewing the patient records, the measurements sent by the patient over the past 8 days show that the patient had a (b)(6).The investigation determined the reason for the weight increase flag is that the system intervention rule evaluates the difference of the largest and the smallest value over the defined number of days.If the change in measurement meets the requirements, the intervention rule flags.The decrease measurement works similarly, it evaluates difference between the smallest value and largest value over a defined number of days.If the change in measurement meets the requirements after the set number of days the intervention rule flags.The two rules are applied separately, and as the patient experienced both a larger weight gain and smaller weight loss, with only the weight gain meeting the requirements, the weight gain was flagged.
