Influence of work values and personality traits on intent to stay among nurses at various types of hospital in Taiwan.

AIM: In this study, the influence of work values and personality traits on the intent to stay at work was examined among nurses in Taiwan. BACKGROUND: No empirical studies in this area have been conducted in the nursing industry. METHODS: A cross-sectional predictive study was performed during 2012 with 1246 nurses recruited from three different types of hospital located in northeastern Taiwan. A structured questionnaire based on the 5-factor model was used. Multiple regression analyses were used to investigate the various factors associated with the intent to stay at work among nurses. RESULTS: The overall response rate was 85%. The nurses who had a high level of intent to stay at work were significantly more likely to be in senior roles; exhibited positive work values, conscientiousness, emotional stability; and worked at a non-religious hospital. CONCLUSION: Age, the role of work values, personality traits and type of hospital were crucial in enhancing the level of intent to stay at work. IMPLICATIONS FOR NURSING MANAGEMENT: The study findings provide evidence for managers to develop an optimal strategy for nurses with specific personality traits and highly positive work values, which can guide the recruitment and retention of nurses.

Sleep quality and morningness-eveningness of shift nurses.

AIM AND OBJECTIVE: The aim of the study was to analyse, while controlling for identified covariates, the effects of morningness-eveningness on sleep quality for shift nurses. BACKGROUND: Shift nurses had greater difficulty falling asleep or staying asleep, thus resulting in higher rates of retiring from hospital. Existing research has addressed the effects of manpower demand and personal preferences on shift assignment; however, the concept of endogenous rhythms is rarely considered. METHODS: This analysis included 137 nurses between the ages of 21-58. Nurses completed the Horne and Ostberg questionnaire to assess morningness-eveningness and the Pittsburgh Sleep Quality Index (PSQI) questionnaire to measure self-reported sleep quality over the last month. The 18-point Chinese version had a Cronbach's reliability coefficient of 0.79 overall and 0.86 respectively. This study analysed correlates of sleep quality by comparing the groups with better or worse sleep quality according to the median of PSQI. Univariate and multivariate analyses were used for the risk factors of worse sleep quality. RESULTS: The result showed that the strongest predictor of sleep quality was morningness-eveningness not the shift schedule or shift pattern for nurses under controlling the variable of age. Greater age and longer years employed in nursing significantly decreased the risk of worse sleep quality. The confounding age factor was properly controlled; evening types working on changing shifts had higher risk of poor sleep quality compared to morning types. CONCLUSIONS: Morningness-eveningness was the strongest predictor of sleep quality under controlling the variable of age in shift nurses. IMPLICATIONS FOR CLINICAL PRACTICE: Our results suggested that determining if nurses were attributed to morning or evening types is an important sleep issue before deciding the shift assignment.

Randomised controlled trial of music on state anxiety and physiological indices in patients undergoing root canal treatment.

OBJECTIVES: The purpose of this randomised investigator-blind controlled trial is to examine the effects of music on the state anxiety and physiological indices among patients undergoing root canal treatment. DESIGN: Randomised controlled trial. METHODS: Purposive sampling was used to recruit 44 adult subjects. The subjects were randomly assigned to the treatment and the control group. There were 22 subjects in each group. Subjects in the music group listened to selected sedative music using headphones throughout the root canal treatment procedure. The control group subjects worn headphones but without the music. Using a repeated measures design with a single pretest and five posttests, the subjects' heart rate, blood pressure and finger temperature were measured before the study and every 10 minutes until the end of the root canal treatment procedure. Anxiety was measured before the study and at the end of the treatment procedure. RESULTS: The results revealed that there were no significant differences between the two groups for baseline data and procedure-related characteristics, except for gender. However, the subjects in the music group showed a significant increase in finger temperature and a decrease in anxiety score over time compared with the control group. The effect size for state anxiety and finger temperature was 0.34 and 0.14 respectively. RELEVANCE TO CLINICAL PRACTICE: The findings provide evidence for nurses and dentists that the use of soothing music for anxiety reduction in patients undergoing root canal treatment procedures is supported by research findings.

Intensive care unit staff nurses: predicting factors for career decisions.

AIMS AND OBJECTIVES: The aim of this study was to understand the factors related to intention to leave their job among intensive care unit (ICU) nurses in eastern Taiwan and to make between-group comparisons between an intention to leave and an intention to stay as well as to predict the influencing factors that affect ICU staff nurses' intention to leave. BACKGROUND: Nurses' intention to leave their job may have an important impact on the actual turnover of nurses. The issue has always been of concern to nursing executives. Only limited empirical studies in the area have been investigated in an Asian culture context and particularly the eastern Taiwan region. METHODS: A cross-sectional predictive study was performed during 2005 with 130 nurses recruited from two ICUs at a medical centre. A researcher-designed questionnaire based on the Cooper's model with structured interviews was used to determine each nurse's characteristics and their intention to leave their job. Multiple logistic regression analysis was employed to investigate the various factors associated with this. RESULTS: The overall response rate was 100%; 63 (48.9%) revealed that they intended to leave their jobs. The findings were that their self-rated health status, the number of diseases, the level of happiness, the presence of depression, job satisfaction, sleep quality, type of license and their unit were significantly associated with an intention to leave (p = 0.05-0.001). Depression and sleep quality proved to be the most significant predictors of ICU staff nurses' intention to leave their job. CONCLUSIONS: The findings suggest that there is a need to take steps to improve nurses' health-related quality of life and to develop effective strategies to improve nurse retention. RELEVANCE TO CLINICAL PRACTICE: A succinct validated instrument would help identify the important factors that predict ICU nurses' intention to leave their job, which may result in job disengagement. Predictors found in this study may be used as outcome variables for developing such an effective method of improving nurse retention in ICUs.

Freshwater clam extract ameliorates acute liver injury induced by hemorrhage in rats.

The freshwater clam is a widely-consumed shellfish and is used as a remedy for chronic hepatitis in Asia. However, its contribution to acute liver injury (ALI) remains unclear. The aim of this study is to assess the protective effects of freshwater clam extract (CE) in ALI induced by hemorrhage in rats. Rats were randomly divided into 5 groups, (1) blood loss (BL) 40%, (2) CE 150 mg/kg plus BL 40%, (3) CE 75 mg/kg plus BL 40%, (4) CE 150 mg/kg, and (5) CE 75 mg/kg groups. CE was given by femoral vein catheter in Groups 2 to 5. Initial hemorrhage was induced by withdrawing blood (loss 40% of total blood volume) from a femoral arterial catheter after CE administration in Groups 2 and 3. The levels of blood tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) were measured at several time points during the experimental period. Rats were sacrificed after 48 hours, and the liver was harvested for hematoxylin and eosin (HE) stain to show liver tissue injury. The results indicated that hemorrhage significantly decreased mean arterial pressure (MAP), increased blood AST, ALT and LDH levels and induced liver injury. Pre-treatment with the CE increased MAP and IL-10 levels and decreased AST, ALT, LDH and TNF-alpha levels after hemorrhage. The HE stains showed diminished organ injury in the CE groups. In conclusion, freshwater clam extract is a potential immunomodulating agent and ameliorates acute liver injury.

Is nursing profession my first choice? A follow up survey in pre-registeration student nurses.

The purpose of this study was to explore how nursing students' value factors, motivational factors, institutional factors and competence factors contributed to career intent. All fifth-year nursing students (n=231) in a college in eastern Taiwan completed a survey which followed-up a study done 1 year previously in the same population were followed for 1 year. A validated and reliable self-administered questionnaire developed by the investigators in 2004 and modified in 2005 was used in the study. Data on value factors, competence factors, motivational factors, and situational factors were collected. The overall response rate was 87.4%. The rates of considering nursing as their first choice improved from 19.1% at the point of college-entry to 34.6% in 2004 and 46.5% in 2005 in the same cohort students. Past experience with being ill, degree of stress, self-rated clinical competency, perceived support from staff nurses, and perceived value were associated with career decision after the completion of a whole year of clinical practice (p<0.05-0.01). In multivariate analysis, perceived support from staff nurses, past experience with being ill, and perceived value proved to be significant predictors of the career intent of pre-registration student nurses. Nursing faculty and nurse administrators need to provide assistance to reduce nursing students' career attrition.

Randomized crossover trial studying the effect of music on examination anxiety.

The purpose of this study was to assess the effect of lento music on examination anxiety among nursing students. A randomized crossover classroom-based trial was conducted. Thirty-eight students with a mean age of 19.4 years (SD = .54) were randomly assigned to either a music/silence or a silence/music group sequence. The students in the music group were given a 40-min group-based music intervention in a classroom, whereas the students in the silence group received the regular test without music. Using paired t-tests, there were no significant different in pretest scores for state anxiety, examination anxiety, finger temperature and pulse rate between the two conditions. Nonetheless, the findings indicated that music intervention did effectively decrease examination anxiety and state anxiety as well as reducing pulse rate and increasing higher finger temperature (p = 0.05 to 0.001). In addition, significant differences were detected between the pretest and posttest measures for silence (p = 0.001). The results suggest that lento music is effective at anxiety reduction. This study provides evidence for nursing faculty and clinical educators to foster nursing students' mastering over the anxiety of examination by using lento music.

Factors associated with career decision in Taiwanese nursing students: a questionnaire survey.

The vocational decisions of nursing students have always been a concern for nursing educators and administrators. It is unclear, however, what factors play a role in determining the professional choices made by these students. Limited research into this area has been undertaken in Taiwan. This study, therefore, was designed to investigate the factors associated with career choices in Taiwan's nursing students. The convenience sample included all fourth-year nursing students of a college in eastern Taiwan. A validated and reliable self-administered questionnaire developed by the investigators was used in the study. The sample population consisted of 231 fourth-year nursing students. Notably, 65.4% reported that they would not choose nursing as a career after graduation. Significant variables associated with this career decision were clinical ability (t=2.35, p<0.05), degree of stress during clinical practice (t=-3.04, p<0.01), and perceived support from staff nurses (t=2.28, p<0.05). These results suggest that both educators and administrators need to reconsider the way nursing students are educated, and indicate that strategies must be developed to enhance students' motivation to select nursing as a career.

Randomized controlled trial of music during kangaroo care on maternal state anxiety and preterm infants' responses.

The purpose of this randomized controlled trial was to investigate the influences of music during kangaroo care (KC) on maternal anxiety and preterm infants' responses. There are no experimental studies that explore the influences of combination of music and KC on psychophysiological responses in mother-infant dyads. Purposive sampling was used to recruit 30 hospitalized preterm infants body weight 1500 gm and over, gestational age 37 weeks and lower from two NICUs. Mother-infant dyads were randomly assigned to the treatment and the control group using permuted block randomization stratified on gender. There were 15 mother-infant dyads in each group. Subjects in the treatment dyads listened to their choice of a lullaby music during KC for 60 min/section/day for three consecutive days. Control dyads received routine incubator care. Using a repeated measures design with a pretest and three posttests, the responses of treatment dyads including maternal anxiety and infants' physiologic responses (heart rate, respiratory rate, and O2 saturation) as well as behavioural state were measured. The results revealed that there were no significant differences between the two groups on infants' physiologic responses and the values were all in the normal range. However, infants in the treatment group had more occurrence of quiet sleep states and less crying (p<0.05-0.01). Music during KC also resulted in significantly lower maternal anxiety in the treatment group (p<0.01). Maternal state anxiety improved daily, indicating a cumulative dose effect. The findings provide evidence for the use of music during KC as an empirically-based intervention for bahavioural state stability and maternal anxiety in mother-infant dyads.

The physiological changes of cumulative hemorrhagic shock in conscious rats.

Hemorrhagic shock is a common cause of death in emergency rooms. Current animal models of hemorrhage encounter a major problem that the volume and the rate of blood loss cannot be controlled. In addition, the use of anesthesia obscures physiological responses. Our experiments were designed to establish an animal model based on the clinical situation for studying hemorrhagic shock. Hemorrhagic shock was induced by withdrawing blood from a femoral arterial catheter. The blood volume withdrawn was 40% of the total blood volume for group 1 and 30% for group 2 and 3. Group 3 was anesthetized with sodium pentobarbital (25 mg/kg, i.v.) at the beginning of blood withdrawal. Our data showed that the survival rate was 87.5% at 48 h in the conscious group and 0% at 9 h in anesthetic group after hemorrhage. The levels of mean arterial pressure, heart rate, white blood count, TNF-alpha, IL1-beta, CPK, and LDH after blood withdrawal in the anesthetic group were generally lower than those in conscious groups. These results indicated that anesthetics significantly affected the physiology of experimental animals. The conscious, unrestrained and cumulative volume-controlled hemorrhagic shock model was a good experimental model to investigate the physical phenomenon without anesthetic interfernce.
