Trajectory of smoking behaviour during the first 6 months after diagnosis of lung cancer: A study from Taiwan.

AIMS: To identify different classes of change pattern/ trajectory of tobacco smoking behaviour after diagnosis of lung cancer using multi-wave data and to explore factors associated with the class membership. DESIGN: This is a multi-wave observational study. METHODS: Smoking behaviour data were collected at diagnosis and then every month for 6 months from 133 newly diagnosed people with lung cancer who had recently quit smoking or continued to smoke at diagnosis. These patients were recruited from three medical centres and data were collected from May 2014 to January 2017. Smoking behaviour was assessed based on patients' self-reports on whether they smoked during the last month (yes/no) for a total of seven times. Mixture latent Markov model and logistic regression were used to analyse data. RESULTS: Two latent classes of smoking trajectory were identified among recent quitters or current smokers of people with lung cancer, namely "perseverance for abstinence" and "indecisive for abstinence." Patients who were younger age (OR = 0.95, p = 0.026), exposure to second-hand smoke (OR = 3.35, p = 0.012) and lower self-efficacy for not smoking (OR = 0.96, p = 0.011) were more likely to belong to the class of "indecisive for abstinence." CONCLUSIONS: Heterogeneous classes of smoking trajectory existed in newly diagnosed people with lung cancer. The risk factors associated with a less favourable smoking trajectory can be incorporated into tailored smoking-cessation programs for patients newly diagnosed with lung cancer. IMPACT: The dynamic trajectory of smoking behaviour had not been adequately explored among newly diagnosed people with lung cancer. Two classes of smoking trajectory and the predictors associated with the class membership were identified. These findings suggest that the diagnosis of cancer is a teachable moment for smoking cessation. Patients with younger age, lower self-efficacy of not smoking and exposure to second-hand smoke at home need special attention.

Gender Differences in the Prevalence of Metabolic Syndrome Among Taiwanese Air Force Personnel: A Population-Based Study.

BACKGROUND: Authors of several studies have reported differences in the prevalence of metabolic syndrome (MetS) between men and women. However, information is lacking on gender difference among military personnel. OBJECTIVE: The aim of this study was to examine the prevalence of MetS and its component abnormalities among Taiwanese Air Force personnel by gender and age groups. METHODS: A population-based study was conducted including 14 872 Taiwanese Air Force personnel. Data were retrieved from the military's Health Management Information System. Analyses were performed using Student t test, χ test, and linear-by-linear χ test. Statistical significance was defined as P < .05. RESULTS: The MetS prevalence was 14.0% (15.1% in men and 5.3% in women). Metabolic syndrome was associated with age for both men and women (both Ptrend < .001), with a greater prevalence of MetS in men aged 18 to 44 years than in women, but not in the age group of 45 years or older. In men, MetS was most prevalent in those with increased waist circumference (78.2%), followed by those with elevated blood pressure (75.6%). By contrast, in women, it was most prevalent in those with increased waist circumference (86.5%), followed by those with reduced high-density lipoprotein cholesterol (84.3%). CONCLUSIONS: Our findings suggest that military nurses and other health providers should consider the gender- and age-based MetS prevalence trend among Taiwanese Air Force personnel when designing interventions to identify vulnerable subgroups at a high risk of MetS. Health management programs should be adapted to minimize metabolic risks.

[Toward 2020 the International Year of the Nurse and the Midwife: Linking Taiwan Nursing With the World].

To commemorate the 200th birthday of Florence Nightingale, the World Health Organization announced 2020 as the "International Year of the Nurse and the Midwife." Nursing is in the frontline of transformational care. The actions of nurses help bring positive changes to the world. Taiwan cannot stand outside of the global community. The Taiwan Nurses Association is also involved actively in international affairs. The expertise and enthusiasm of Taiwan's nurses may be highlighted by attending and responding to various meetings, conferences, and global nursing events organized by the International Council of Nurses (ICN) such as the Council of National Nursing Association Representatives (CNR), ICN Congress, and Nursing Now campaign. This article shares important information and insights on the 2019 ICN CNR meeting and the ICN Congress to expand the international perspective of nurses and to inspire and explore the future development of the nursing profession in Taiwan.

Path modeling of knowledge, attitude and practice toward palliative care consultation service among Taiwanese nursing staff: a cross-sectional study.

BACKGROUND: The Taiwanese government has promoted palliative care consultation services (PCCS) to support terminally ill patients in acute ward settings to receive palliative care since 2005. Such an intervention can enhance the quality of life and dignity of terminally ill patients. However, research focusing on the relationship between the knowledge, attitude and practice of a PCCS using path modelling in nursing staff is limited. Therefore, the aim of this study was to elucidate the effect of path modeling on the knowledge, attitude and practice toward PCCS in Taiwanese nursing staff. METHODS: This was a cross-sectional, descriptive study design using convenience sampling. Data collected included demographics, knowledge, attitude and practice as measured by the PCCS inventory (KAP-PCCSI). Two hundred and eighty-four nursing staff from a medical center in northern Taiwan participated in the study in 2013. We performed descriptive statistics, regression analysis, and path modeling using SPSS 19.0 and set p < 0.05 as the statistical significance threshold. RESULTS: The results showed that the identical factor significantly associated with knowledge, attitude, and practice toward PCCS among nurses was the frequency of contact with PCCS. In addition, higher level of knowledge toward PCCS was associated with working in haematology and oncology wards, and participation in education related to palliative care. A more positive attitude toward PCCS was associated with working in a haematology and oncology ward, and experience of friends or relatives dying. Higher level of practice toward PCCS was associated with nurses who participated in education related to palliative care. In the path modeling, we found that holders of a master's degree indirectly positive affected practice toward PCCS. Possession of a bachelor degree or above, being single, working within a haematology and oncology ward, and frequency of contact with PCCS positively affected practice toward PCCS. CONCLUSIONS: Based on this study, it is proposed that consultation with PCCS has a positive impact on the care of terminally ill patients. Encouragement of staff to undertake further education can improve the practice of ward staff providing palliative care.

Using a New Measurement to Evaluate Pain Relief Among Cancer Inpatients with Clinically Significant Pain Based on a Nursing Information System: A Three-Year Hospital-Based Study.

OBJECTIVE: Developing a new measurement index is the first step in evaluating pain relief outcomes. Although the percentage difference in pain intensity (%PID) is the most popular indicator, this indicator does not take into account the goal of pain relief. Therefore, the aims of this study were to develop a pain relief index (PRI) for outcome evaluation and to examine the index using demographic characteristics of cancer inpatients with clinically significant pain. DESIGN: Retrospective cohort study. SETTING: A national hospital. SUBJECTS: All cancer inpatients. METHODS: Pain intensity was assessed using a numerical rating scale, a faces pain scale or the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Tool. Using a nursing information system, a pain score database containing data from 2011 through 2013 was analyzed. RESULTS: Cancer patients representing 93,812 hospitalizations were considered in this study. We focused on cancer patients for whom the worst pain intensity (WPI) was ≥ 4 points. PRI values of -62.02% to -72.55% were observed in the WPI ≥ 7 and 4 ≤ WPI ≤ 6 groups. Significant (P < 0.05) effects on PRI values were observed among patients who were > 65 years old, those who were admitted to the medicine or gynecology and those who had a hospital stay > 30 days. CONCLUSION: This hospital-based study demonstrated that the PRI is an effective and valid measure for evaluating outcome data using an electronic nursing information system. We will further define the meaningful range of percentage difference in PRI from various perspectives.

Evaluation of uraemic pruritus in long-term dialysis patients using a modified Chinese scale.

AIM: To examine the reliability and validity of a modified Chinese version of the uraemic pruritus scale for measurement of different degrees of itching, as well as to identify the predictors for the severity of uraemic pruritus among long-term dialysis patients. METHODS: Long-term dialysis patients (n = 110) were recruited for a cross-sectional study from a medical centre in Taiwan. A modified Chinese version of the uraemic pruritus scale was used to evaluate sleep disturbance and the severity, frequency and distribution of itching. Reliability was evaluated using item-total correlations, Cronbach's α, and intra-class correlation. Validity was evaluated by the content validity index, predictive and discriminative validity. Multiple linear regression was used on the predictors for the severity of uraemic pruritus. RESULTS: After optimization for reliability, the scale retained seven items. The Cronbach's α was 0.86, and the results showed that the scale had predictive and discriminative validity. High intact-parathyroid hormone and creatinine clearance rate were important predictors for the severity of uraemic pruritus. The severity of uraemic pruritus was the important predictor for the sleeping disturbance. CONCLUSION: The modified uraemic pruritus scale can discriminate between patients with a total pruritus score of ≥11 and those with a score of 0 points. The modified Chinese scale is a useful tool for clinically assessing the various degrees of itching among long-term dialysis patients. Our study validates that it could apply to clinical practice in assessment of uraemic pruritus.

Examining the causal model linking health literacy to health outcomes of asthma patients.

AIMS AND OBJECTIVES: To explore health literacy status in asthma patients and to examine the causal model linking health literacy to health outcome-related factors via mediator and moderator variables. BACKGROUND: Understanding how low health literacy may influence health outcomes is important. DESIGN: This is a cross-sectional survey study. METHODS: A total of 326 asthma patients aged 20 years and older (average: 51 ± 18·3 years) were recruited by purposive sampling from pulmonary medicine outpatient departments at three medical centres and a regional teaching hospital in northern Taiwan. Data were collected via structured questionnaires, including measures of socio-demographic and disease characteristics; medical decision-making; asthma knowledge, attitudes and self-efficacy; healthcare experience and health outcome-related factors (metered-dose inhaler/dry-powder inhaler usage proficiency, medical use, self-management behaviour). Three hundred patients who met the inclusion criteria and completed the questionnaire survey were analysed. RESULTS: Overall, 217 subjects (72·3%) had adequate functional health literacy, 42 (14%) had inadequate functional health literacy, and 41 (13·7%) had marginal functional health literacy. Subjects' average asthma knowledge, attitudes and self-efficacy scores were 7·23 ± 2·69, 51·46 ± 6·18 and 58·31 ± 8·10, respectively. Health literacy correlated positively with asthma knowledge (r = 0·605), attitudes (r = 0·192) and medical decision-making (r = 0·413). CONCLUSIONS: Health literacy is positively associated with proficiency in metered-dose inhaler usage, asthma knowledge, attitudes and medical decision-making, but is not significantly associated with medical care use and self-management behaviour. Health literacy had an indirect effect on self-management behaviour through the mediation effect of asthma attitudes. No moderator was found for the effect of health literacy on health outcome-related factors. RELEVANCE TO CLINICAL PRACTICE: Results of this study may help to develop adequate intervention strategies to improve the health outcomes of asthma patients.

Effects of an early postoperative walking exercise programme on health status in lung cancer patients recovering from lung lobectomy.

AIMS AND OBJECTIVES: To examine the effects of an early postoperative walking exercise programme on postlobectomy lung cancer patients. BACKGROUND: Few interventional studies on the postoperative health status of lung cancer patients have considered the efficacy of programmes designed to improve critical health variables. DESIGN: A two-group quasi-experimental, longitudinal approach repeated four times examined participant data collected 12-18 hours prior to surgery and again at one, three and six months after surgery. METHODS: We assigned the first 33 enrolled participants to the intervention group and the second 33 to the control group. The intervention was a daily supervised walking exercise programme consisting of 12 weeks of brisk walking exercise that began on the day following transfer to the regular ward along with weekly telephone calls until 12 weeks after discharge. Health status was measured using a structured questionnaire (World Health Organization Quality of Life, brief version) and clinical tests (pulmonary function test and 6-minute walk test). We analysed data using general estimating equations, with p < 0·05 considered significant. RESULTS: Intervention group pulmonary and physical functions were increasingly better over time than those of the control group, with no significant difference in quality of life between the two groups. Compared to the control group, the intervention group earned significantly better values for FVC% at postoperative month 3 and for FEV1 % at postoperative months 3 and 6. Intervention group 6MWT scores were significantly better than those of the control group at postoperative months 1, 3 and 6. CONCLUSION: This study demonstrated the benefits of an early postoperative walking exercise intervention for pulmonary and physical function in postlobectomy lung cancer patients. RELEVANCE TO CLINICAL PRACTICE: The results may guide the design of appropriate interventions in the future. Clinical trials in other populations are needed to confirm the results of this study.

[Preparing Taiwan nurses for professional practice: a discussion of current international trends].

Taiwan is currently considering revising the minimum educational requirements for becoming a licensed registered nurse (RN). This article analyzes this issue from an international perspective within the framework of Taiwan's experience. Suggestions regarding possible approaches are given.

[Centennial retrospective on the evolution and development of the nursing profession in Taiwan].

This article explores the evolution and development of the Taiwanese nursing profession. After introducing the origins of nursing, this article proceeds to introduce nursing during various periods in Taiwan, including the early-Qing Dynasty, foreign missionary nursing, the Japanese Colonial Era, and the Nationalist Chinese Era following World War Two up to the present. The authors then present the current situation in the Taiwanese nursing profession in terms of gender issues, high-technology developments, educational issues, the nursing licensing examination, hiring and training, multiple role functions, and the skill-mix care model. Finally, the authors make recommendations for the further development and improvement of the nursing profession in Taiwan.

[The new era of evidence-based nursing: comprehensive mobilization and development of the nursing sciences].

Science is subject to inevitable evolutionary change. Philosopher of science Thomas Kuhn defined a scientific revolution as a period in time during which a particular field of scientific knowledge is set to transition to a new paradigm that will propel it toward a new milestone. Because person-centered care embraces the universal values of trans-disciplinary healthcare teams, evidence-based healthcare represents a paradigm shift toward evidence-based nursing. The rapid development of evidence-based practice is an evolutionary process of revolutionary importance to science. The resulting era of evidence-based nursing will help fully realize the development potential of the nursing sciences. This article introduces the process of knowledge construction in evidence-based nursing, reviews the literature to identify the general model used to promote evidence-based nursing internationally, and proposes practical strategies to promote evidence-based nursing in Taiwan. We hope this article will help further promote the clinical application of evidence-based nursing and the development of nursing science.

[Resilience in cancer patients and related nursing interventions].

Cancer is a critical health problem in Taiwan. The range of physical, psychological, social, and existential stressors associated with cancer diagnosis and treatment can cause significant distress in cancer patients and survivors. The focus of cancer research has broadened in the past decade from the disease itself to factors that can have a positive influence on the health and life quality of cancer patients. However, few studies have explored how patients adapt and become resilient to the life challenges of their disease. This article introduces the concept of resilience and its influence factors. We analyze study findings and introduce four nursing interventions that have been used to nurture resilience in cancer patients. The authors hope findings help strengthen nurse competencies in order to enhance cancer patient quality of care.

The determinants of health-related quality of life among patients with newly diagnosed lung cancer in Taiwan: A cross-sectional study.

BACKGROUND: Although considered one of the most important prognostic factors for lung cancer patients, the health-related quality of life (HRQOL) of the newly diagnosed lung cancer population remains scarcely focused on in the literature. Therefore, we aimed to identify the determinants of HRQOL among newly diagnosed lung cancer patients in Taiwan. METHODS: Two hundred and fifty patients newly diagnosed with lung cancer were recruited from a medical center in northern Taiwan through convenience sampling. Four structured questionnaires, including the Taiwanese version of the MD Anderson symptom inventory (MDASI-T), the Taiwanese version of the Pittsburgh Sleep Quality Index (PSQI-T), the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and the World Health Organization Quality of Life-BREF (WHOQOL-BREF), were used to collect data. Further, a multivariate stepwise linear regression was conducted to determine the independent risk factors for HRQOL. A p value of less than 0.05 was considered statistically significant. RESULTS: The patients (mean age was 61.04 years, 51.2% male, 94.0% non-small-cell lung cancer, 56.4% stage IIIB-IV) had moderate levels of HRQOL among the physical, psychological, social, and environmental domains, as well as overall QOL. HRQOL was not correlated with married status, religion, and comorbidity. Gender, age, family income, smoking status, cancer stage, ECOG PS scores, PA, symptom burden (severity and interference), and PSQI global scores were correlated with HRQOL. Notably, symptom severity was the dominant negative predictor affecting the psychological and environmental domains of QOL (ß = -4.313 and -3.500, respectively), accounting for 23.2% and 14.6% of the variance, respectively. On the other hand, symptom interference was the dominant negative predictor affecting the physical and social domains of QOL, as well as overall QOL (ß = -3.592, -1.984, and -0.150, respectively), accounting for 44.4%, 15.0%, and 24.1% of the variance, respectively. CONCLUSION: Newly diagnosed lung cancer patients suffered symptom severity and interference that significantly impaired their HRQOL; particularly, symptom interference affected the physical domain of QOL. Healthcare professionals should pay more attention to cancer-related symptom severity, symptom interference, and HRQOL changes when caring for newly diagnosed lung cancer patients.

Correlation of N-terminal-pro-brain natriuretic peptide with postoperative outcomes of older patients undergoing transcatheter aortic valve replacement.

BACKGROUND: Patients undergoing transcatheter aortic valve replacement surgery (TAVR) are typically older adults with multiple chronic diseases and therefore have a high surgical risk. The N-terminal of brain natriuretic peptide (BNP) and pro-BNP, referred to as NT-pro-BNP, is an easily measurable biomarker of heart failure. Studies on correlation between higher NT-pro-BNP levels and adverse prognoses after TAVR have yielded inconsistent results. Here, we investigated whether preoperative NT-pro-BNP levels are correlated with outcomes among older adults undergoing TAVR. METHODS: This retrospective study included older adults with severe aortic stenosis (AS) who received TAVR from a medical center between January 2013 and June 2017. The patients' demographics, preoperative laboratory data, postoperative complications, and 1-year mortality were recorded. They were divided into two groups based on their preoperative NT-pro-BNP levels. The post-TAVR outcomes in the two groups were analyzed using a multivariate logistic regression analysis of the binary results. RESULTS: Of the 132 patients included (mean age: 81.5 ± 8.1 years; 47% men), 96 (72.7%) had preoperative NT-pro-BNP levels ≤ 4853 ng/L, and 36 (27.3%) had preoperative NT-pro-BNP levels > 4853 ng/L. The postoperative outcomes were significantly better in the NT-pro-BNP≤4853 group than in the NT-pro-BNP>4853 group: postoperative extracorporeal membrane oxygenation fittings (4.2% vs 16.7%, p = 0.025), number of days in hospital (17.5 ± 21.0 vs 27 ± 17.0, p = 0.009), in-hospital mortality (4.2% vs 16.7%, p = 0.025), and 1-year mortality (11.5% vs 38.9%, p = 0.001); the significant differences persisted after controlling for other variables. CONCLUSION: For older patients undergoing TAVR with NT-pro-BNP levels > 4853 ng/L, their postoperative outcomes and 1-year mortality were correlated. Thus, NT-pro-BNP is useful for the risk assessment of patients undergoing TAVR and should be regarded as a biomarker in future risk assessments.

Influence of family caregiver caring behavior on COPD patients' self-care behavior in Taiwan.

BACKGROUND: COPD becomes a long-term burden on family members who serve as day-to-day caregivers, and causes healthcare systems to incur substantial costs. COPD is both preventable and treatable, and one important aspect of COPD treatment is patients' self-management. This study aimed to investigate relationships between self-management and the caregiver burden, and the influence of family caregivers' caring behavior on COPD patients' self-care behavior. METHODS: In a cross-sectional study conducted between March 2007 and January 2008, 192 pairs of COPD patients (age > 40 years, normal cognitive function) and their primary family caregivers were recruited to answer questionnaires measuring COPD characteristics and COPD knowledge (patients and caregivers); functional status, health beliefs, self-efficacy, and self-care (patients); and caring behavior and caregiver response (family members). All questionnaires were shown to have acceptable validity and reliability, and the data were analyzed using univariate and multivariate techniques. RESULTS: Patients' ages, scores in health belief, self-efficacy and disease-related knowledge were shown to correlate with patients' self-care behavior. Patients' self-care behavior was negatively correlated with family caregivers' caring behavior (ρ = -0.21, P = .003), but positively with caring duration of family caregiver caring behavior (ρ = 0.15, P = .037). Patients with a spouse as caregiver exhibited higher self-care ability than patients not married to their caregivers (P = .038). However, patients' self-care behavior decreased with higher family caregivers' COPD knowledge (P = .041) and caring behavior (P = .01), and patients regularly taking medication exhibited low self-care scores. CONCLUSIONS: Family caregivers' caring behavior had a partial negative effect on COPD patients' self-care behavior.

Effectiveness of influenza vaccination in the elderly: a population-based case-crossover study.

BACKGROUND: There is limited information regarding the effectiveness of influenza vaccines for older adults. Particularly, controlling for healthy senior bias is challenging in observational studies. We aimed to assess the efficacy of influenza vaccination in the elderly while addressing potential healthy senior bias and whether it was related to virus-vaccine strains matching. METHOD: To control between-individual confounder, we used a case-crossover study design using Taiwan's National Health Insurance Research Dataset to analyse the association between influenza vaccination in older adults and the risk of hospitalisation for community-acquired pneumonia (CAP). Individuals were a 'case' in vaccinated years and a 'control' in unvaccinated years. The study periods were 2006/2007 and 2007/2008 seasons because virus-vaccine strains were matching in 2006/2007 season and unmatching in 2007/2008 season. Older adults were categorised into two groups: admitted for CAP during the pre-vaccination period (Admitted, n=311) and not hospital admitted for CAP (Non-admitted, n=572 432). The outcome was hospitalisation for CAP during the influenza period. Conditional logistic regression assessed influenza vaccine efficacy in reducing CAP. RESULTS: Influenza vaccination had no protective effects in Admitted group. However, because of the tiny numbers in Admitted group, we could draw very limited conclusions. Receiving an influenza vaccine significantly prevented CAP in Non-admitted group only during the vaccine-circulating strain-matched year (OR, 0.72; 95% CI, 0.64 to 0.83). In addition, there was no protective effect against CAP hospitalisation among individuals with a Charlson Comorbidity Index score over 2. CONCLUSION: Influenza vaccine efficacy was associated with vaccine-circulating strain-matched. When vaccine-circulating strains were all matching, receiving a shot reduced the probability of CAP hospitalisation by 28% in Non-admitted group. However, high comorbidity may reduce the vaccine efficacy. Therefore, it is necessary to educate older adults to receive annual influenza vaccination and in combination with non-pharmaceutical interventions to reduce the risk of CAP.

Facing death, facing self: nursing students' emotional reactions during an experiential workshop on life-and-death issues.

AIM AND OBJECTIVES: This study presents the findings of a qualitative study exploring the experiences of undergraduate nursing students imagining the possibility of their own death during a workshop on life-and-death issues. BACKGROUND: Didactic instruction in end-of-life care is a critical element of nursing education and for most health professions training in general. Properly implementing this often-overlooked educational process requires providing students with opportunities to reflect on death and dying along with guidance during nursing practice in coping with emotional reactions to caring for dying patients. DESIGN: An interpretive descriptive design was adopted. METHOD: Data were gathered from the text of 20 students' reflective journals and workshop evaluations and researchers' field notes on observations during the workshop at a Taiwan university in August 2007. RESULTS: Students experienced a process of dying, death and rebirth. Students not only expressed emotional responses that included surprise, reluctance to let go and gratitude but also realised the importance of cherishing the present, committing to the nursing profession and valuing their own lives. CONCLUSIONS: Students can learn their fear of death and possible emotional reactions towards dying patients through self-reflection during a workshop on life-and-death issues. The foundation for facilitating students' self-awareness is a safe environment for them to gain experiential knowledge of the dying process and end-of-life care. Experiential education not only helps students grow personally but also increases their motivation to learn. RELEVANCE TO CLINICAL PRACTICE: Students' ability to recognise and manage their own emotional reactions towards death and dying patients should be included as part of end-of-life education. A workshop on life-and-death issues can help students discover that they are not alone and that they can support each other and learn how to manage their own emotions.

[Clinical management of poor sleep quality in patients with chronic obstruction pulmonary disease].

Sleep disturbance is the most common clinical problem for patients with chronic obstruction pulmonary disease (COPD). Potentially the result of changes in patient breathing patterns, symptoms of the disease, or pharmacological side effects, sleep disturbance can negatively affect COPD patients both physiologically and psychologically. It is therefore important for the medical community to acknowledge the problem through clear observation and suitable application of assessment tools in order to recommend therapies able to promote sleep quality. The article reviews the literature and analyzes clinical cases to discuss the effects of chronic obstruction pulmonary disease on sleep and potential management strategies. I hope this article will be a useful resource for the medical community to improve clinical nursing quality.

["Ineffective breathing pattern" care for COPD patients].

Chronic obstructive pulmonary disease (COPD) is a long-term, chronic respiratory disease from which patients never fully recover. COPD patients usually face abnormal aeration caused by the disease. Patients that are unable to breathe and aspirate adequately and maintain lung appropriate expansion and contraction are considered to have ineffective breathing patterns. This causes physical, psychological and behavioral changes in COPD patients and impacts their emotional condition, daily activities and quality of life. Nurses who care for COPD patients with ineffective breathing patters can improve breathing muscle functions, improve respiration and keep the airway clean. In this paper, the author reviews and integrates relevant findings on this subject from the empirical literature in order to assist clinical nurses responsible for the care of COPD patients.

Trajectory of growth in Taiwanese nursing students' professional self-concept over two years and its association with critical thinking and class climate.

BACKGROUND: Nursing is a practice-oriented profession, and the goal of education is to cultivate confidence and assertiveness for future clinical practice. Nurturing a professional self-concept at school is expecting to help students to approach their success in the nursing profession. PURPOSE: Using a hierarchical model associated with critical thinking, academic achievement, class climate, and work experience, this longitudinal correlational study explored the growth trajectory of professional self-concept over two years in students attending 2- or 4-year baccalaureate nursing programs. METHOD: This was a longitudinal and correlational study with five repeated measurements. Questionnaire data were collected by using the Chinese version of the Nurses Self-Concept Instrument (NSCI-C) and the California Critical Thinking Disposition Inventory (CCTDI). RESULTS: Scores for overall professional self-concept ranged from 84.51 (standard deviation [SD] 12.34) when the students began this study to 89.28 (SD 11.23) at graduation. Hierarchical linear modeling yielded the growth trajectory of professional self-concept was significantly associated with time (ß = 0.93, p < .01), CCTIDI (ß = 0.13, p < .001), and class climate (ß = 5.20, p < .01). An intraclass correlation coefficient was 55.48%. CONCLUSION: This study confirmed the positive growth trajectory of the professional self-concept in the nursing students' two academic years. The continuous development of the professional self-concept of nursing students is encouraged. Development of critical thinking through their studies, feelings of belonging in their classes, and campus culture all contributed to this trend. To construct a comprehensive hierarchical model, future investigations should use large sample sizes from various classes and conduct multisite evaluations.
