Evaluation of an oral care protocol intervention in the prevention of chemotherapy-induced oral mucositis in paediatric cancer patients

Oral mucositis is the most frequent and severe complication of chemotherapy in children with cancer that can aggravate the childs clinical condition and increase the risk of infection. This prospective comparative study was designed to determine the effectiveness of a preventive oral care protocol in reducing chemotherapy-induced oral mucositis in children with cancer. During an 8-month period, 42 children aged 6 to 17 years with haematological malignancies or solid tumours were evaluated. The 21 children who were included in the first 4-month period of the study constituted the control group. Another 21 children were enrolled in the subsequent 4 months and were assigned to the experimental group, in which they were given an oral care protocol intervention. The oral care protocol consisted of tooth brushing, 0.2% chlorhexidine mouth rinse and 0.9% saline rinse. Children in both groups were evaluated twice a week for 3 weeks. The incidence of ulcerative lesions, severity of oral mucositis and the related pain intensity were used as the main outcome variables. A 38% reduction in the incidence of ulcerative mucositis was found in children using the oral care protocol compared with children in the control group. The severity of oral mucositis (P=0.000002) and the related pain (P=0.0001) were significantly reduced with the intervention. These results support the preventive use of the oral care protocol in paediatric cancer patients who undergo chemotherapy for cancer treatment.

Predictors of quality of life following stroke

Purpose : To determine the factors predicting quality of life during the course of rehabilitation following stroke. Method : Two hundred and fifteen stroke patients aged 41-93 were studied over a period of three months. Measurement of quality of life, functional ability, social support, demographic and treatment data were taken on admission to the rehabilitation hospital, at two weeks and three months. The instruments used were the Sickness Impact Profile (SIP), the Modified Barthel Index (MBI) and The Social Support Questionnaire, short form (SSQ6). Results : Length of stay, previous stroke, functional ability and social support were found to be significantly correlated with quality of life. Stepwise multiple regression analysis indicated that functional ability, psychological and physical SIP dimensions, social support satisfaction at two weeks and previous stroke explained 47% of the variance in sickness impact at three months following stroke. The factors predicting 53% of the variance in sickness impact at two weeks were baseline functional ability, psychological and physical SIP. Conclusions : The findings indicate that both psychosocial and physical factors are important in predicting quality of life in stroke rehabilitation. Determining such predictors at an early stage will help to guide clinical decisions throughout rehabilitation.

A Delphi study to validate an advanced practice nursing tool.

AIM This paper is a report of a study conducted to validate an instrument for measuring advanced practice nursing role delineation in an international contemporary health service context using the Delphi technique. BACKGROUND Although most countries now have clear definitions and competency standards for nurse practitioners, no such clarity exists for many advanced practice nurse roles, leaving healthcare providers uncertain whether their service needs can or should be met by an advanced practice nurse or a nurse practitioner. The validation of a tool depicting advanced practice nursing is essential for the appropriate deployment of advanced practice nurses. This paper is the second in a three-phase study to develop an operational framework for assigning advanced practice nursing roles. METHOD An expert panel was established to review the activities in the Strong Model of Advanced Practice Role Delineation tool. Using the Delphi technique, data were collected via an on-line survey through a series of iterative rounds in 2008. Feedback and statistical summaries of responses were distributed to the panel until the 75% consensus cut-off was obtained. RESULTS After three rounds and modification of five activities, consensus was obtained for validation of the content of this tool. CONCLUSION The Strong Model of Advanced Practice Role Delineation tool is valid for depicting the dimensions of practice of the advanced practice role in an international contemporary health service context thereby having the potential to optimize the utilization of the advanced practice nursing workforce.

Premenstrual syndrome in employed Chinese women in Hong Kong

Premenstrual syndrome (PMS) has been studied in many countries, but few studies have been reported internationally on the experience of Chinese women. Because culture and employment are important factors in the perception of health status, in this study we sought to determine the existence and features of PMS in Chinese clerical women in Hong Kong. We used a cross-sectional, retrospective approach to collect data with a translation of an established questionnaire (the Menstrual Distress Questionnaire). Fatigue was found to be the most prevalent symptom, and the Pain, Water Retention, Behavioral Change, and Negative Affect scales had more than 64% frequency. The main difference between these findings and those of other studies is that negative affect featured most prominently in Western samples, whereas pain featured most highly in this sample of Chinese women.

A pilot study on the effect of progressive muscle relaxation training of patients after stoma surgery

Eighteen patients who had undergone stoma surgery were assessed with respect to their anxiety level and self-reported quality of life (QoL) on three occasions; namely, immediately after surgery, 5 weeks after surgery, and 10 weeks after surgery. The patients were randomised into a control group (n = 10) and an experimental group (n = 8). A 20-min set of audiotaped instructions on progressive muscle relaxation training (PMRT) was given to the patients in the experimental group for home practice. Assessment instructions included the Chinese State-Trait Anxiety Inventory (C-STAI), the Quality of Life Index for Colostomy (QoL-Colostomy) and the Hong Kong Chinese version of the World Health Organisation Quality of Life Scale (WHOQoL). Results indicated that there was a significant decrease in both the C-STAI score (F = 4.66, P < 0.05) and the WHOQoL score (F = 4.74, P < 0.05) in the experimental group. Among the domains of WHOQoL, a significant difference was shown in physical health/independence and general perception of QoL, with the experimental group demonstrating better functioning. For the QoL-Colostomy, however, there was no significant difference between the control and experimental groups. The results suggest that the use of PMRT could enhance quality of life and decrease state anxiety in patients after stoma surgery.

Applying the Transtheoretical Model of Change to exercise in young Chinese people.

OBJECTIVES: The objective of the present study was to test the application of the Transtheoretical Model of Change (TTM) in relation to exercise behaviour of 298 Hong Kong Chinese undergraduates. DESIGN AND METHODS: A cross-sectional design was used. Respondents completed measures of stages of change, self-efficacy, processes of change, decisional balance, exercise and demographic data. RESULTS: Significant effects for stage of change were found for self-efficacy, pros, exercise and nine of the 10 processes of change. In general, scores on these variables were found to increase across the stages although post hoc tests revealed slightly different patterns of significant differences. Cons were not found to differ significantly across stages of change. The relationship between self-efficacy and processes of change was dependent on stage of change. CONCLUSIONS: The results support some of the assumptions of the TTM but raise questions about the predicted relationships between stages of change and processes of change and between self-efficacy and processes of change at each stage of change. The practical implications of the findings for the development of interventions to improve young peoples exercise levels are discussed.

Knowledge of and Attitudes Toward Sex among Chinese Adolescents

This study was conducted to examine the knowledge of and attitudes toward sex of 178 Chinese secondary school students in Hong Kong. The data were collected using a questionnaire that comprised three parts: the Chinese version of the Mathtech Knowledge Test, the Chinese version of the Mathtech Attitude and Value Scale, and a demographic sheet seeking sociodemographic information. In general, students demonstrated a low level of sexual knowledge, especially in relation to adolescent marriage, the probability of pregnancy, and adolescent sexual activity. With regard to attitudes, students indicated positive attitudes toward importance of family and importance of birth control. Male students in comparison with their female counterparts had a higher level of agreement with premarital intercourse and the use of pressure and force in sexual activity.

Delineating the practice profile of advanced practice nursing: A cross-sectional survey using the modified strong model of advanced practice

AIMS To test a model that delineates advanced practice nursing from the practice profile of other nursing roles and titles. BACKGROUND There is extensive literature on advanced practice reporting the importance of this level of nursing to contemporary health service and patient outcomes. Literature also reports confusion and ambiguity associated with advanced practice nursing. Several countries have regulation and delineation for the nurse practitioner, but there is less clarity in definition and service focus of other advanced practice nursing roles. DESIGN A statewide survey. METHODS Using the modified Strong Model of Advanced Practice Role Delineation tool, a survey was conducted in 2009 with a random sample of registered nurses/midwives from government facilities in Queensland, Australia. Analysis of variance compared total and subscale scores across groups according to grade. Linear, stepwise multiple regression analysis examined factors influencing advanced practice nursing activities across all domains. RESULTS There were important differences according to grade in mean scores for total activities in all domains of advanced practice nursing. Nurses working in advanced practice roles (excluding nurse practitioners) performed more activities across most advanced practice domains. Regression analysis indicated that working in clinical advanced practice nursing roles with higher levels of education were strong predictors of advanced practice activities overall. CONCLUSION Essential and appropriate use of advanced practice nurses requires clarity in defining roles and practice levels. This research delineated nursing work according to grade and level of practice, further validating the tool for the Queensland context and providing operational information for assigning innovative nursing service.

Stress associated with tasks for family caregivers of patients with cancer in Hong Kong

Family caregivers share the strain of cancer and are at risk of physical and psychological symptoms in relation to caregiver stress. This study investigated the relationships between perceived difficulty in managing caregiver tasks and the experience of stress symptoms among 26 family caregivers of terminally ill patients with cancer in Hong Kong. The findings revealed that more stress symptoms were experienced by caregivers who had reported increased difficulty in managing caregiver tasks (rs = 0.64; p < 0.001). Wilcoxon signed-ranks test indicated that psychological stress symptoms, rather than physical symptoms, overwhelmed most of the caregivers (z = -2.15; p < 0.05). There were significantly more negative responses to stress by caregivers who had a shorter duration of experience in providing care. In addition, caregivers who had less education were at higher risk of developing stress (p < 0.01). These findings indicate the need for the provision of support to facilitate the emotional and physical adaptation of caregivers at risk for health problems.

Improved functional ability and independence in activities of daily living for older adults at high risk of hospital readmission: a randomized controlled trial

OBJECTIVE During hospitalization older people often experience functional decline which impacts on their future independence. The objective of this study was to evaluate a multifaceted transitional care intervention including home-based exercise strategies for at-risk older people on functional status, independence in activities of daily living (ADLs) and walking ability. METHODS A randomized controlled trial was undertaken in a metropolitan hospital in Australia with 128 patients (64 intervention, 64 control) aged over 65 years with an acute medical admission and at least one risk factor for hospital readmission. The intervention group received an individually tailored programme for exercise and follow-up care which was commenced in hospital and included regular visits in hospital by a physiotherapist and a registered nurse, a home visit following discharge and regular telephone follow-up for 24 weeks following discharge. The programme was designed to improve health-promoting behaviours, strength, stability, endurance and mobility. Data were collected at baseline, then 4, 12 and 24 weeks following discharge using the Index of ADL, Instrumental Activities of Daily Living (IADL) and the Walking Impairment Questionnaire (WIQ; modified). RESULTS Significant improvements were found in the intervention group in IADL scores (P < 0.001), ADL scores (P < 0.001) and WIQ scale scores (P < 0.001) in comparison to the control group. The greatest improvements were found in the first 4 weeks following discharge. CONCLUSIONS Early introduction of a transitional model of care incorporating a tailored exercise programme and regular telephone follow-up for hospitalized at-risk older adults can improve independence and functional ability.
