Pressure Injury Prediction and Education Model Using a Mobile Application System

Change from the baseline score of the knowledge of pressure injury care to before discharge

The investigators designed the ten questions regarding pressure injury care knowledge to detect caregivers' understanding of pressure injury care. The higher scores reflect a greater understanding of pressure injury care.

Time frame: Data will be collected on admission(baseline-T0) and before discharge(T1).

Change from the baseline score of the pressure injury care self-efficacy of caregivers to before discharge

The fourteen items of the self-efficacy of pressure injury care are designed to detect caregivers' self-efficacy on pressure injury care. Response options on the items range from "no confidence" (1 point) to "every confidence" (5 points). The higher scores reflect greater self-efficacy on pressure injury care.

Time frame: Data will be collected on admission(baseline-T0) and before discharge(T1).

Change from the baseline score of the General Anxiety Disorder-7(GAD-7) to before discharge

The GAD-7 (Spitzer et al., 2006) is a one-dimensional instrument designed to detect generalized anxiety disorder symptoms defined in the DSM-IV. The item scores range from 0 (not at all) to 3 (nearly every day), resulting in a sum score ranging from 0 to 21. The higher scores reflect greater anxiety severity.

Time frame: Data will be collected on admission(baseline-T0) and before discharge(T1).

Change from the baseline score of the Patient Health Questionnaire-9(PHQ-9) to before discharge

The nine items of the PHQ-9 are designed to capture the nine Diagnostic and Statistical Manual of Mental Disorders (DSM) symptom criteria for a major depressive episode. Response options on the items range from "not at all" (0 points) to "nearly every day" (3 points). As a severity measure, the PHQ-9 score can range from 0 to 27.

Time frame: Data will be collected on admission(baseline-T0) and before discharge(T1).
