Predicting pressure sore risk with the Norton, Braden, and Waterlow scales in a Hong Kong rehabilitation hospital

BACKGROUND Numerous pressure sore risk calculators have been developed since the 1960s. Each scale is claimed to have predictive value and applicability in various clinical settings, but it has not been determined which one is more relevant for adoption in a rehabilitation setting. OBJECTIVES To compare the predictive power of the three most commonly adopted pressure sore risk calculators: Norton, Braden, and Waterlow scales. METHOD One hundred six patients, free of pressure sores at admission, were assessed using the three scales by independent assessors within 48 hours of admission, followed by a daily monitoring of skin condition for at least 14 days to detect any sore that developed. RESULTS Both the Norton and Waterlow scales had relatively high sensitivity (81% and 95%, respectively), whereas the Braden Scale had both high sensitivity (91%) and specificity (62%). All three scales had relatively high negative predictive values (>90%), but the Braden Scale had better positive predictive value. CONCLUSIONS The Braden Scale is more suitable for use in a rehabilitation hospital.

Pressure ulcer development in older residents in nursing homes: influencing factors

AIM This paper is a report of a study assessing pressure ulcer incidence and factors affecting pressure ulcer development among older nursing home residents. BACKGROUND Previous researchers have shown that demographic, clinical, health status, risk and human resources factors affect pressure ulcer development among older people in various healthcare settings, but none has investigated their interactive effects among older nursing home residents. METHOD This was a prospective cohort study involving 346 residents aged 65 years or over from four private nursing homes in Hong Kong. We collected information on participant demographics and assessed their clinical characteristics, health status and pressure ulcer risk factors. Subsequently, we assessed their skin condition every 2 days for 4 weeks to detect pressure ulcers that developed after the initial assessment. The data were collected between December 2006 and September 2007. RESULTS The pressure ulcer incidence was 25.16%. The model in which the factors of clinical characteristics, health status, pressure ulcer risk and human resources were controlled was more reliable in predicting pressure ulcer development than the other two models. It showed that bedfast or chairfast residents, especially those with co-morbidities (renal failure and stroke) and living in nursing homes where there were no nurses but more nursing assistants, were at higher risk for pressure ulcer development. CONCLUSION Evidence-based interventions should be adopted to minimize the possible problems of pressure, malnutrition, friction and shear force, and the decreased pain perception of bedfast or chairfast residents in nursing homes, especially those with renal failure or stroke.

Assessing predictive validity of the modified Braden scale for prediction of pressure ulcer risk of orthopaedic patients in an acute care setting

AIMS AND OBJECTIVES To assess and compare the predictive validity of the modified Braden and Braden scales and to identify which of the modified Braden subscales are predictive in assessing pressure ulcer risk among orthopaedic patients in an acute care setting. BACKGROUND Although the Braden scale has better predictive validity, literature has suggested that it can be used in conjunction with other pressure ulcer risk calculators or that some other subscales be added. To increase the predictive power of the Braden scale, a modified Braden scale by adding body build for height and skin type and excluding nutrition was developed. DESIGN A prospective cohort study. METHOD A total of 197 subjects in a 106-bed orthopaedic department of an acute care hospital in Hong Kong were assessed for their risk for pressure ulcer development by the modified Braden and Braden scales. Subsequently, daily skin assessment was performed to detect pressure ulcers. Cases were closed when pressure ulcers were detected. RESULTS Out of 197 subjects, 18 patients (9.1%) developed pressure ulcers. The area under the receiver operating characteristic curve for the modified Braden scale was 0.736 and for the Braden scale was 0.648. The modified Braden cut-off score of 19 showed the best balance of sensitivity (89%) and specificity (62%). Sensory perception (Beta = -1.544, OR=0.214, p = 0.016), body build for height (Beta = -0.755, OR = 0.470, p = 0.030) and skin type (Beta = -1.527, OR = 0.217, p = 0.002) were significantly predictive of pressure ulcer development. CONCLUSION The modified Braden scale is more predictive of pressure ulcer development than the Braden scale. RELEVANCE TO CLINICAL PRACTICE The modified Braden scale can be adopted for predicting pressure ulcer development among orthopaedic patients in an acute care setting. Specific nursing interventions should be provided, with special attention paid to orthopaedic patients with impaired sensory perception, poor skin type and abnormal body build for height.

A Comparative Study of Chinese, American and Japanese Nurses’ Perceptions of Ethical Role Responsibilities

This article reports a survey of nurses in different cultural settings to reveal their perceptions of ethical role responsibilities relevant to nursing practice. Drawing on the Confucian theory of ethics, the first section attempts to understand nursing ethics in the context of multiple role relationships. The second section reports the administration of the Role Responsibilities Questionnaire (RRQ) to a sample of nurses in China (n = 413), the USA (n = 163), and Japan (n = 667). Multidimensional preference analysis revealed the patterns of rankings given by the nurses to the statements they considered as important ethical responsibilities. The Chinese nurses were more virtue based in their perception of ethical responsibilities, the American nurses were more principle based, and the Japanese nurses were more care based. The findings indicate that the RRQ is a sensitive instrument for outlining the embedded sociocultural factors that influence nurses’ perceptions of ethical responsibilities in the realities of nursing practice. This study could be important in the fostering of partnerships in international nursing ethics.

Drawing a qualitative distinction of caring practices in a professional context: the case of Chinese nursing.

How to draw a qualitative distinction between nursing work and the work of a servant has been a major concern for nurses in China. This article explains the ways in which nurses in China articulate the meaning of caring in practice situations. Seventy nurses in Beijing were invited to share their experience about what caring meant to them as nurses and examples of caring in practice situations. Van Kaams phenomenologic method of controlled explication was used to analyze the data. The findings reveal that these Chinese nurses are able to articulate the cheng and jing versions of caring practices that emphasize flexible, pluralist, contextualized, individualized, and subjectively informed practices. To further this study, we would suggest nurses be more proactive in starting a dialogue with society so as to seek nursings legitimate practice that can foster responsive care to patients and society on the one hand and the professional integrity of nursing on the other.

Stabilizing and destabilizing forces in the nursing work environment: A qualitative study on turnover intention

Abstract Background The nursing work environment, which provides the context of care delivery, has been gaining increasing attention in recent years. A growing body of evidence points to an inseparable link between attributes of the nursing work environment and nurse and patient outcomes. While most studies have adopted a survey design to examine the workforce and work environment issues, this study employed a phenomenological approach to provide empirical evidence regarding nurses’ perceptions of their work and work environment. Aim The aim of this study was to advance our understanding of the phenomenon of increasing nurse turnover through exploring frontline registered nurses’ lived experiences of working in Hong Kong public hospitals. Methods and participants A modified version of Van Kaams controlled explication method was adopted. Individual semi-structured interviews were conducted with 26 frontline nurses recruited from ten acute regional, district and non-acute public hospitals in Hong Kong. Their perspectives in regard to their work and work environment, such as workload, manpower demand and professional values, were extensively examined, and a hypothetical description relating the nursing work environment with nurses’ turnover intention was posited. Results Contemplation of nurses’ experiences revealed the vulnerable aspects of nursing work and six essential constituents of the nursing work environment, namely staffing level, work responsibility, management, co-worker relationships, job, and professional incentives. These essential constituents have contributed to two sets of forces, stabilizing and destabilizing forces, which originate from the attributes of the nursing work environment. Nurses viewed harmonious co-worker relationships, recognition and professional development as the crucial retaining factors. However, nurses working in an unfavorable environment were overwhelmed by destabilizing forces; they expressed frustration and demonstrated an intention to leave their work environment. Conclusions The nursing work environment is a complex entity comprising multiple constituents; its attributes affect nurses’ perceptions of their work and work environment, which warrant special attention in addressing the phenomenon of increasing nurse turnover.

The Blessings and the Curses of Filial Piety on Dignity at the End-of-Life: Lived Experience of Hong Kong Chinese Adult Children Caregivers

This study critically examines the evolving nature of filial piety and the role that it plays in the contemporary experience of “living and dying with dignity” among Hong Kong Chinese families facing the end of life. Meaning-oriented interviews were conducted with a purposive sample of 15 adult-children caregivers, ages 30 to 62, to elicit their narratives and stories in caring for a dying elderly parent. Qualitative content analysis reveals that although traditional filial beliefs provided motivation for family caregiving, the regrets of unfulfilled filial responsibilities create emotional distance between parents and adult children, which acts as a cultural barrier for reconciliation and contentment at lifes final margin. These findings underscore the importance of intergenerational dynamics and interactions in the transformation of filial attitudes and behaviors, highlighting the importance of reciprocal relationships (versus authority relationship), mutual support (versus complete obedience), compassionate duty (versus obligatory duty), emotional connection (versus task fulfillment), and appreciation and forgiveness (versus guilt and shame) in the promotion of dignity at the end of life. Policy and clinical implications are discussed.

Factors Associated with Resilience of Adult Survivors Five Years after the 2008 Sichuan Earthquake in China

Given the paucity of quantitative empirical research on survivors’ resilience and its predictors in the context of long-term recovery after disasters, we examined how resilience predictors differed by gender among adult survivors five years after the Sichuan earthquake. This was a cross-sectional survey study of adult survivors (N = 495; aged 18–60) living in reconstructed communities five years into the recovery process after the Wenchuan earthquake. The instruments we used included assessments of sociodemographic characteristics and earthquake exposure level, the Connor-Davidson Resilience Scale, and the Social Support Rating Scale. Support-seeking behaviors emerged as a significant predictor of male survivors’ resilience, while subjective support and marital status were found to be predictors of female survivors’ resilience. Annual household income and chronic disease were predictors for both male and female groups. The findings of this study can be used in devising methods to boost survivors’ resilience by promoting their satisfaction with social support and their ability to obtain effective support. Additionally, the results suggest how to assist survivors who may have relatively poor resilience.

Effect of a life review program for Chinese patients with advanced cancer: a randomized controlled trial.

BACKGROUND Empirical data suggest that life review is an effective psychospiritual intervention. However, it has not been applied to Chinese patients with advanced cancer, and its effects on this population remain unknown. OBJECTIVE The aim of the study was to determine the effect of a life review program on quality of life among Chinese patients with advanced cancer. METHODS In this prospective randomized controlled trial, a total of 80 patients were randomly assigned to the life review program group and the control group. The 3-weekly life review program included reviewing a life and formulating a life review booklet. Outcome data were assessed by a collector who was blinded to group assignment before and immediately after the program and at a 3-week follow-up. RESULTS Significantly better scores in overall quality of life, support, negative emotions, sense of alienation, existential distress, and value of life were found in the life review group immediately after the program and at the 3-week follow-up. CONCLUSION This study provides additional data on the potential role of a life review in improving quality of life, particularly psychospiritual well being; it also indicates that the life review program could enable Chinese patients with advanced cancer to express their views on life and death. IMPLICATIONS FOR PRACTICE The life review program offers advanced cancer patients an opportunity to integrate their whole life experiences and discuss end-of-life issues, which lays the ground for further active intervention in their psychospiritual distress. The program could be integrated into daily home care to enhance the psychospiritual well-being of Chinese patients with advanced cancer.

Ethical Analysis of Non-Medical Fetal Ultrasound:

Obstetric ultrasound is the well-recognized prenatal test used to visualize and determine the condition of a pregnant woman and her fetus. Apart from the clinical application, some businesses have started promoting the use of fetal ultrasound machines for nonmedical reasons. Non-medical fetal ultrasound (also known as ‘keepsake’ ultrasound) is defined as using ultrasound to view, take a picture, or determine the sex of a fetus without a medical indication. Notwithstanding the guidelines and warnings regarding ultrasound safety issued by governments and professional bodies, the absence of scientifically proven physical harm to fetuses from this procedure seems to provide these businesses with grounds for rapid expansion. However, this argument is too simplistic because current epidemiological evidence is not synchronous with advancing ultrasound technology. As non-medical fetal ultrasound has aroused very significant public attention, a thorough ethical analysis of this topic is essential. Using a multifaceted approach, we analyse the ethical perspective of non-medical fetal ultrasound in terms of the expectant mother, the fetus and health professionals. After applying four major theories of ethics and principles (the precautionary principle; theories of consequentialism and impartiality; duty-based theory; and rights-based theories), we conclude that obstetric ultrasound practice is ethically justifiable only if the indication for its use is based on medical evidence. Non-medical fetal ultrasound can be considered ethically unjustifiable. Nevertheless, the ethical analysis of this issue is time dependent owing to rapid advancements in ultrasound technology and the safety issue. The role of health professionals in ensuring that obstetric ultrasound is an ethically justifiable practice is also discussed.
