This study was conducted to describe the attitude toward pressure ulcer prevention, knowledge and non-compliance risk for pressure ulcer prevention practice and degrees of nursing performance, as well as to examine the relationship among these variables. To accomplish this, we invited 397 nurses from four hospitals to complete surveys of attitude toward pressure ulcer prevention, knowledge and certainty for pressure ulcer prevention practice, and degrees of nursing performance. Non-compliance risk for pressure ulcer prevention practice was derived from the difference between knowledge and certainty for pressure ulcer prevention. The data were collected from March to June 2017 and analyzed by descriptive statistics, independent t-tests, ANOVA, and partial Pearson's correlation coefficient testing. The correct answer rate regarding the knowledge of pressure ulcer prevention practice was 79%, and the degree of pressure ulcer prevention nursing performance was $2.46{\pm}0.31$. The highest item of the non-compliance risk for pressure ulcer prevention practice was incontinence diapers prevent incontinence-associated dermatitis. There were significant negative correlations between non-compliance risk for pressure ulcer prevention practice and knowledge (r=-0.25, p<0.001), and degree of pressure ulcer prevention nursing performance (r=-0.13, p=0.009). Continuous education and furnishing practical guidelines for pressure ulcer prevention should be implemented to improve knowledge and certainty of pressure ulcer prevention practice.

The medical bed developed in this study is an electrically driven segmental keyboard. First describe the instrument of the segmental bed specially designed for pressure ulcer prevention, then the motor control system and pressure ulcer prevention operation of the bed. The main factor of pressure ulcer generation is displayed as body pressure x time, and when the keyboard falls, the body pressure becomes zero, and the pressure becomes higher than the threshold even if the body pressure is above the threshold, the pressure control algorithm has been developed. Therefore, using the proposed pressure control method, it has no particular ulcer occurred theoretically.

Purpose: The purpose of this study was to construct and test a structural equation model for pressure ulcer prevention action by clinical nurses. The Health Belief Model and the Theory of Planned Behavior were used as the basis for the study. Methods: A structured questionnaire was completed by 251 clinical nurses to analyze the relationships between concepts of perceived benefits, perceived barriers, attitude, subjective norm, perceived control, intention to perform action and behavior. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting pressure ulcer prevention action among clinical nurses. Results: The model fitness statistics of the hypothetical model fitted to the recommended levels. Attitude, subjective norm and perceived control on pressure ulcer prevention action explained 64.2% for intention to perform prevention action. Conclusion: The major findings of this study indicate that it is essential to recognize improvement in positive attitude for pressure ulcer prevention action and a need for systematic education programs to increase perceived control for prevention action.

Purpose: The purpose of this study was to investigate attitudes and preventive practice of pressure ulcer among hospital nurses and identify factors affecting their preventive practice of pressure ulcer. Methods: Data were collected at April, 2011 in a university hospital in Korea. A total of 140 hospital nurses completed a questionnaire including attitudes and preventive practice of pressure ulcer. Data were analyzed with descriptive statistics, Spearmans rho, and stepwise multiple regression via SPSS/WIN 20.0. Results: Levels of attitudes and preventive practice of pressure ulcer were average 3.65 out of 5 and 2.19 out of 3 respectively. There was significant difference in preventive practice of pressure ulcer by area of practice ($x^2$= 43.35, p<.001), frequency of pressure ulcer care ($x^2$=10.72, p=.013), and experience of wound care education (Ζ=4.73, p=.030). The attitudes toward pressure ulcer prevention were positive correlated to preventive practice among nurses (rho=.190, p=.049). Area of practice, attitude toward pressure ulcer prevention and experience of wound care education explained 48% of variance in preventive practice of pressure ulcer. Conclusion: For improving quality of care, it is important to provide educations to change nurses attitudes toward preventive practice of pressure ulcer.

Purpose: The purpose of this study was to develop an algorithm for preventing and managing of pressure ulcer and to verify the its appropriateness. Methods: The first step was development of a pre-algorithm through a literature review and expert opinion. The second step was to establish content validity by submitting the algorithm questionnaires about the content to 12 experts. The third step was the revision of the algorithm. The fourth and last step was to establish the clinical validity of the algorithm with 25 experienced nurses. Results: For the ease of the practitioner the algorithm for prevention and the management of pressure ulcers was confined to one page depicting the main algorithm pathway and seven stepwise guidelines. The guidelines included skin care of pressure ulcer prevention, mechanical loading care, support surface care, reposition care of pressure ulcer, and Stages II, III and IV explanations along with debridement/wound irrigation and infection control. Most of all algorithm courses chosen more than 80% of agreement by expert index of content validity. The usefulness, appropriateness, and convenience of the algorithm were demonstrated through clinical validity with intensive care unit and ward nurses. Conclusion: The algorithm will improve the quality of pressure ulcer nursing care as it provides a model for decision making for clinical nurses as well as providing consistent and integrated nursing care for patients with pressure ulcer throughout an institution.

Purpose: This study aimed to identify the incidence and risks for pressure ulcer among older patients with hip fracture. Methods: The subject were 215 older patients suffering from hip fracture who were admitted for surgical operation from January 1, 2012 to April 30, 2016 in a university-affiliated hospital. The incidence of pressure ulcer was collected retrospectively through medical record review and the risk factors were analyzed using Cox's proportional hazard model. Results: Out of the total, 32 patients (14.9%) developed pressure ulcer with the average occurrence period being 4.72 (${\pm}3.81$) days. Stage II pressure ulcer was the most common at 72.0%. Risk factors included ambulation status before injury (p= .039), spinal anesthesia (p= .029), and stay at intensive care unit after operation (p= .009). Conclusion: Despite pressure ulcer prevention efforts, the incidence remained relatively high. Considering the identified risk factors, more efforts is needed for early detection and prevention of pressure ulcers in such patients.

Despite numerous air mattresses marketed to prevent Pressure Ulcers (PU), none have fully succeeded due to residual pressure surpassing critical levels. We introduces an innovative medical bed system aiming at complete PU prevention. This system employs a unique 4-bar link mechanism, moving keys up and down to manage body pressure. Each of the 17 keys integrates a sensor controller, reading pressure from 10 sensors. By regulating motor input, we maintain body pressure below critical levels. Keys are equipped with a servo drive and sensor controller, linked to the main controller via two CAN series. Using fuzzy or PI/IP controllers, we adjust keys to minimize total error, dispersing body pressure and ensuring comfort. In case of controller failure, keys alternate swiftly, preventing ulcer development. Through experimental tests under varied conditions, the fuzzy controller with tailored membership functions demonstrated swift performance. PI control showed rapid convergence, while IP control exhibited slower convergence and oscillations near zero error. Our specialized medical robot bed, incorporating 4-bar links and pressure sensors, underwent testing with three controllers-fuzzy, PI, and IP-showcasing their effectiveness in keeping body pressure below critical ulcer levels. Experimental results validate the proposed approach's efficacy, indicating potential for complete PU prevention.

The purpose of this study was to examine the degree of knowledge of care workers working at long term care hospitals and nursing homes on pressure ulcer. A total of 81 care workers including 34 at long term care hospitals and 47 at nursing homes were surveyed. 24 questions were used to evaluate their degree of knowledge on pressure ulcer. Their knowledge on pressure ulcer scored 12.84 out of the total score of 24 points(SD=3.40), which was equal to 53.50 (SD=24.23) out of 100 points. Their knowledge on the prevention of pressure ulcer was highest among the subareas of evaluation. Their knowledge on pressure ulcer statistically significantly differed according to education on pressure ulcer(P<.05). A pressure ulcer is a skin disorder that may be prevented and cured. At this point when long term care facilities are rapidly increasing, care workers highlevel knowledge on and good management of pressure ulcer is very important. Practically educating them on pressure ulcer including the provision of recent, updated relevant knowledge will be necessary.
