A portable, battery-powered per-patient device automatically detects and logs patient encounters with items, such as medical equipment, drug containers, caregivers, visitors and other patients, in a healthcare facility. A separate per-patient device is assigned to each patient in the facility. The per-patient device is intended to remain with the patient during the patient's stay. The device may be attached to the patient's bed, wheelchair, walker or the like. If the patient is ambulatory, the patient may carry the device. RF-ID or other suitable tags are attached to items that a patient may encounter. Each per-patient device automatically detects and logs RF-ID-tagged items, including the patient, that come within a range of the device. The device also detects and longs when an item is no longer within range of the device, such as because a caregiver leaves the patient's room or a medical device is removed from the patient's room. The per-patient device also detects and logs when an item is reunited with a patient. Information, such as a time and date on which an RF-ID tag is detected or ceases to be detected, may be included in the log. The logged information may be used to obtain status or location information about the items. In addition, if an item or a patient is found to be infected, all the people or items that encountered the item or patient can be listed by querying the log.
