1. A dressing and/or securement device for a catheter, comprising:
a support member configured to receive a portion of the catheter therethrough, the support member including:
a first temperature sensor configured to obtain a first temperature measurement at a first location on a body of a patient adjacent a catheter insertion site of the catheter; and
an array of temperature sensors configured to obtain a plurality of temperature measurements at a plurality of locations on the body of the patient, wherein each temperature sensor of the array of temperature sensors is spaced apart from the first temperature sensor on the support member, and wherein the array of temperature sensors comprises temperature sensors at a plurality of different distances from the first temperature sensor;
a wired or wireless communication device configured to communicate the first temperature measurement and the plurality of temperature measurements; and
one or more processors configured to receive the first temperature measurement and the plurality of temperature measurements from the wired or wireless communication device, wherein the one or more processors are programmed and/or configured to:
determine a plurality of first temperature differences between the first temperature measurement and each of the plurality of temperature measurements;
determine, based on the plurality of first temperature differences, an alert condition associated with the dressing and/or securement device for the catheter and/or the catheter; and
in response to the determination of the alert condition, generate an alert for transmission to a device.
