In this study, individuals will be monitored for 28 days. They will be asked to fill out the Pressure Injury Information Form and the Pressure Injury Skills Checklist for Caregivers to be informed about pressures throughout the study process. The researcher will fill out the Bates-Jensen Wound Assessment Tool to ensure that their pressures are improving. Individuals who will undergo the intervention will use the mobile application. Face-to-face training will be provided to individuals. Individual-specific audio reminders will be based on daily living activities and will be delivered via the mobile application according to changes in individual dependencies. After 30 days, individuals will be asked to fill out the Mobile Health Application Acceptance Scale, the Pressure Injury Knowledge Scale for Caregivers, and the Pressure Injury Skills Checklist. The Bates-Jensen Wound Assessment Tool will be filled out by the researcher.

The assessment tool developed by Bates-Jensen et al. in 1992 is a scale that broadly addresses the physiological and anatomical characteristics of the wound. It consists of 13 items: size, depth, edges, tunneling, type and amount of necrotic tissue, type and amount of exudate, color of the skin around the wound, peripheral tissue edema and induration, granulation tissue and epithelialization. As a result of the scale scoring, 1 point indicates that the wound is in better condition, while 5 points indicate that the wound condition is worse. In the presence of necrotic tissue, the type and amount of necrosis are also included in the assessment. The total score obtained varies between 13-65, and an increase in the score indicates that the wound condition is worsening.

The Pressure Injury Patient Information Form was prepared by the researcher in line with the literature. There are questions about the management of pressure injuries. The form consists of 15 questions. Each question is 1 point, the lowest score is "0" and the highest score is "15". As the score increases, the knowledge of individuals to manage pressure injuries increases. Before starting the research, expert opinions will be presented and arrangements will be made.

The Pressure Injury Skill Form was prepared by the researcher in line with the literature. The form consists of 10 items. For each item, "Not Applied" was evaluated as "0" points, "Partially Applied" as "1" points, and "Applied" as "2" points. The lowest score to be received from the checklist is "0" and the highest score is "20". An increase in the score indicates that the individual's pressure injury skills have improved. Before starting the research, it will be presented to expert opinions and arrangements will be made.
