Tai Chi and Health-Related Quality of Life in Nursing Home Residents

PURPOSE Health-related quality of life (HRQOL) that is good is regarded as the goal of elderly residential care. However, limited evidence exists indicating a promising intervention that can achieve this goal. The aim of this study is to examine the effect of Tai Chi on HRQOL in nursing home residents. DESIGN A nonequivalent pretest-posttest control-group design. METHODS A convenience sample of 139 residents from six nursing homes in Hong Kong was used. The experimental group (n=66) joined a 26-week Tai Chi program, while the control group (n=73) continued with usual daily activities. The physical and mental components of HRQOL were designated as the dependent variables. Resident satisfaction was considered as a covariate. Doubly multivariate repeated measures analysis of covariance was done to examine the intervention effect. FINDINGS After adjusting for the confounding effect of resident satisfaction, a statistically significant difference (p<0.05) in the physical and mental components of HRQOL between the experimental and control groups was found. Findings showed significant improvement in HRQOL after residents practiced Tai Chi. CONCLUSIONS These investigators contribute additional knowledge about the health benefits of Tai Chi among nursing home residents and indicates support for its use in this population to improve HRQOL. CLINICAL RELEVANCE Tai Chi has unique characteristics as a health exercise that is particularly suitable for nursing home residents. The inclusion of Tai Chi exercise in elderly residential care practice is recommended.

The psychosocial effect of Tai Chi on nursing home residents

AIM To determine the psychosocial effect of Tai Chi on nursing home residents. BACKGROUND Moving into a nursing home usually imposes a certain degree of psychosocial challenge to older people. However, there is limited evidence suggesting a promising intervention that can promote the psychosocial health for this group. Although previous studies suggest that Tai Chi has the potential to enhance psychosocial well-being, existing evidence is deemed scarce and thus imposes a limitation on drawing out conclusions on this matter. DESIGN Non-equivalent pretest-posttest control group design. METHODS A convenience sample of 139 residents from six nursing homes in Hong Kong was recruited for this study. The experimental group (n = 66) participated in a 26-week Tai Chi programme, while the control group (n = 73) continued its normal daily activities. The outcome measures included state self-esteem, the physical and mental component of health-related quality of life, social support network and social support satisfaction. Resident satisfaction was identified as a covariate because it demonstrated significant correlation with the outcome variables and, likewise, showed significant difference between the two study groups at baseline. Doubly multivariate analysis of covariance was performed to examine the effect of the intervention. RESULTS Results indicate significant Group x Time interactions, with the experimental group experiencing significant improvement in the composite outcome of state self-esteem, the physical component of health-related quality of life and the mental component of health-related quality of life across the 26-week study period [F(6, 131) = 2.61, p = 0.02)]. No significant changes were detected regarding the effect of the Tai Chi programme on social support. CONCLUSION Tai Chi practice is beneficial for nursing home residents. RELEVANCE TO CLINICAL PRACTICE Tai Chi has unique characteristics that are particularly suitable in the practice of health exercise for nursing home residents. The inclusion of Tai Chi in residential care practice for older people is recommended.

Depressive symptoms among community-dwelling, post-stroke elders in Hong Kong.

LAM S.C., LEE L.Y.K. & TO K.W. (2010) Depressive symptoms among community-dwelling, post-stroke elders in Hong Kong. International Nursing Review57, 269–273 Background:  Depressive symptoms adversely affect functional recovery among post-stroke elders. Such symptoms manifest when elders face difficulties in realistic daily living after being discharged. Aims:  The aim of this study was to examine (1) the prevalence of depressive symptoms among community-dwelling post-stroke elders, (2) the relationship between depressive symptoms and demographic and clinical characteristics among community-dwelling post-stroke elders, and (3) the demographic and clinical factors that differentiate post-stroke elders with and without depressive symptoms. Methods:  A descriptive cross-sectional survey was performed on 50 post-stroke elders from a geriatric day clinic. Findings:  Depressive symptoms were highly prevalent (68%) among the community-dwelling post-stroke elders. Depressive symptoms were negatively correlated with social support network, social support satisfaction and functional independence. Lastly, poor social support satisfaction and lower functional independence was found to differentiate those post-stroke elders with and without depressive symptoms. Conclusion:  The inclusion of psychosocial assessment and delivery of appropriate psychosocial interventions to post-stroke elders are recommended.BACKGROUND Depressive symptoms adversely affect functional recovery among post-stroke elders.

The establishment of an integrated skills training centre for undergraduate nursing education

AIM This paper details the experience of establishing an integrated skills training centre for use in undergraduate nursing education in The Open University of Hong Kong. BACKGROUND Skills training is an essential element in undergraduate nursing education. Owing to the increasing complexity of the health-care system and patient health needs, undergraduate nursing students should be well prepared for integrated skills competency, critical thinking and rapid decision-making. To achieve this goal, the use of simulation as a skills training tool is being recommended. CONCLUSION The Clinical Nursing Education Centre is established. It adopts simulation as a teaching and learning tool. It has four specific education units, namely: (1) clinical simulation education unit, (2) virtual reality education unit, (3) nursing skills education unit, and (4) Chinese medicinal education unit. These units are specifically designed for the teaching and learning of nursing skills related to general, mental and Chinese medicinal nursing from elementary to advanced level. Experiences pertaining to the conceptualization, exploration and actualization phases of the establishment are presented. Details of the structure and specific functions of the centre are also illustrated. Finally, there is discussion on the challenges encountered during the establishment process and how they were overcome.

Pedometer‐Determined Physical Activity and Body Composition in Chinese Working Adults

Purpose: Overweight and obesity are prevalent public health problems in many developed and developing regions. Despite extensive documentation on the health benefits of physical activities, little is known about the level of physical activity in the Hong Kong Chinese population. Working adults, in particular, deserve primary attention because they account for the largest proportion of Hong Kong society. The purposes of this study were to investigate pedometer-determined physical activity and examine the associations between physical activity and body composition variables among Chinese working adults in Hong Kong. Design: This study adopted a descriptive cross-sectional design. Methods: A quota sample of 913 working adults from nine major occupational categories was recruited. Demographic characteristics and body composition parameters (weight, height, and waist and hip circumferences) were assessed. Body mass index and waist-to-hip ratio were then calculated. Physical activity was measured in terms of daily walking steps using a pedometer over 1 week. Participants were then categorized as “inactive,”“somewhat active,” or “regularly active.” Descriptive and inferential statistics (analysis of variance, t test, and χ2 test) were used appropriately. Findings: Of the 913 participants, 893 returned complete step count records. The completion rate was 97.8%. Participants on average walked 8,661 steps per day, suggesting a “somewhat active” populace. Significant differences were found between the group “regularly active” and “inactive” in most of the body composition parameters. However, a significant weak correlation was found between physical activity and body mass index (r= 0.12, p= .001). Such findings deserve further investigation. Conclusions: The Chinese working adults in Hong Kong were found to be somewhat active in physical activity. Clinical Relevance: Findings pose implications for healthcare professionals who are responsible for health promotion in the Asian community setting. Leisure-type physical activity, such as walking, can be incorporated into daily routines.

Evaluation of the user seal check on gross leakage detection of 3 different designs of N95 filtering facepiece respirators

Background The use of N95 respirators prevents spread of respiratory infectious agents, but leakage hampers its protection. Manufacturers recommend a user seal check to identify on-site gross leakage. However, no empirical evidence is provided. Therefore, this study aims to examine validity of a user seal check on gross leakage detection in commonly used types of N95 respirators. Methods A convenience sample of 638 nursing students was recruited. On the wearing of 3 different designs of N95 respirators, namely 3M-1860s, 3M-1862, and Kimberly-Clark 46827, the standardized user seal check procedure was carried out to identify gross leakage. Repeated testing of leakage was followed by the use of a quantitative fit testing (QNFT) device in performing normal breathing and deep breathing exercises. Sensitivity, specificity, predictive values, and likelihood ratios were calculated accordingly. Results As indicated by QNFT, prevalence of actual gross leakage was 31.0%-39.2% with the 3M respirators and 65.4%-65.8% with the Kimberly-Clark respirator. Sensitivity and specificity of the user seal check for identifying actual gross leakage were approximately 27.7% and 75.5% for 3M-1860s, 22.1% and 80.5% for 3M-1862, and 26.9% and 80.2% for Kimberly-Clark 46827, respectively. Likelihood ratios were close to 1 (range, 0.89-1.51) for all types of respirators. Conclusions The results did not support user seal checks in detecting any actual gross leakage in the donning of N95 respirators. However, such a check might alert health care workers that donning a tight-fitting respirator should be performed carefully.
