The effect of a training course in aggression management on mental health nurses' perceptions of aggression: a cluster randomised controlled trial.

Nurses' attitudes towards patient aggression may influence their behaviour towards patients. Thus, their enhanced capacity to cope with aggressive patients may nurture more positive attitudes and alleviate adverse feelings emanating from patient aggression. This cluster randomised controlled trial conducted on six psychiatric wards tested the hypotheses that a 5 day training course in aggression management would positively influence the following outcome measures: Nurses' perception and tolerance towards patient aggression and resultant adverse feelings. A repeated measures design was employed to monitor change. No effect was found. The short time frame between the training course and the follow up measurement or non-responsiveness of the measurement instruments may explain this finding.

The perception of aggression by nurses: psychometric scale testing and derivation of a short instrument.

Patient aggression is a serious problem in psychiatric nursing. Nurses' attitudes towards aggression have been identified as mediating the choice of nursing interventions. To date, investigations are lacking which elucidate the stability of one of the few scales for measuring the attitude of aggression. This study aimed to investigate the test-retest stability of the Perception of Aggression Scale and to derive a shortened version. In order to test the reliability of the Perception of Aggression Scale items, three groups of psychiatric nurses were requested to fill in the Perception of Aggression Scale twice (30 student nurses after 4 days, 32 qualified nurses after 14 days and 36 qualified nurses after 70 days). We derived the shortened version from an independent data set obtained from 729 psychiatry nurses using principal component analysis, aiming to maximize parsimony and Cronbach's alpha. Amongst competing short versions, we selected those with the highest reliability at 70 or 14 day retest. A scale using 12 of the original 32 items was derived yielding alphas of r = 0.69 and r = 0.67 for the two POAS factors with retest reliabilities of r = 0.76 and r = 0.77. The shortened scale offers a practical and viable alternative to the longer version.

Predicting inpatient violence in acute psychiatric wards using the Brøset-Violence-Checklist: a multicentre prospective cohort study.

The Norwegian Brøset-Violence-Checklist (BVC) is one of the few instruments that is suitable for short-term prediction of violence of psychiatric inpatients by nursing staff in routine care. The instrument assesses the presence or absence of six behaviours or states frequently observed before a violent incident. We conducted a study to elucidate whether the predictive properties of the BVC are retained in other psychiatric settings than the original north-Norwegian validation dataset. During their admission period, 219 consecutive patients admitted to six acute psychiatric wards were assessed as to the risk for attack using a German version of the BVC (BVC-G). Data on preventive measures were concurrently collected. Aggressive incidents were registered using an instrument equivalent to the Staff Observation of Aggression Scale (SOAS-R). Fourteen attacks towards staff were observed with incident severity ranging from 5 to 18 of a possible 22 points. BVC-G sensitivity was 64.3%, the specificity 93.9%, the positive predictive value 11.1%, and the area under the receiver operating characteristic curve 0.88. In some false positive cases intense preventive measures had been implemented. The predictive accuracy of the BVC-G proved consistent with the Norwegian original.

The effectiveness of two interventions in the management of patient violence in acute mental inpatient settings: report on a pilot study.

Systematic risk assessment and training courses have been suggested as interventions to deal with patient violence in psychiatric institutions. A dual centre prospective feasibility study was conducted on two Swiss psychiatric admission wards to test the hypothesis that such interventions will reduce the frequency and severity of violent events and coercion. A systematic aggression risk assessment, in combination with a standardized training course in aggression management was administered and the frequency and severity of aggressive incidents and the frequency of coercive measures were registered. The incidence rates of aggressive incidents and attacks showed no significant reduction from the baseline through risk prediction and staff training, but the drop in coercive measures was highly significant. A 'ward effect' was detected with one ward showing a decline in attacks with unchanged incidence rates of coercion and the other ward showing the opposite. The severity of the incidents remained unchanged whilst the subjective severity declined after the training course. We conclude that a systematic risk assessment and a training course may assist in reducing the incidence rate of coercive measures on psychiatric acute admission wards. Further testing of the interventions is necessary to measure the effect of the training alone and to counteract 'ward effects'.

[Care dependency in nursing homes--a psychometric study].

The Dutch Care Dependency Scale, an instrument for the assessment of a patient's care dependency, has been translated into German. The purpose of this study was to examine the reliability and validity of the German version of the scale. The 15-item scale has been developed for the use in nursing homes. Data were collected from 81 people living in nursing homes in Berlin, Germany. The sample was measured three times. Cronbach's alpha was 0.94. Interrater and intrarater reliability revealed moderate to substantial Kappa statistics. As the results of this study were satisfying, positive recommendations regarding the suitability of the German version of the Care Dependency Scale for use in nursing homes could be made. However, further psychometric testing of the scale is recommended.

Patients' autonomy in surgical care: a comparison of nurses' perceptions in five European countries.

BACKGROUND: This report forms part of the results of an international comparative study funded by the European Commission (1998-2001). AIM: To describe and compare the maintenance of patients' autonomy on surgical wards, from the point of view of nursing staff, in five European countries (Finland, Spain, Greece, Germany and Scotland). Autonomy is defined in terms of information received and decision making by patients. METHOD: The data were collected using a questionnaire specifically designed for use in this study. Responses (response rate 66%) were obtained from 1280 nurses working on surgical wards. Data analysis was based on descriptive statistics, t-tests, analysis of variance (ANOVA) with posthoc Tukey's HSD test and logistic regression. RESULTS: There were clear between-country differences in nurses' perceptions, especially on a north-south axis (Finland and Scotland vs. Greece and Spain), regarding the extent to which the autonomy of surgical patients is supported by nursing staff. Training and ethics education, in particular, were associated with nurses' perceptions of the maintenance of patient autonomy in Finland and Greece. CONCLUSION: Further research is needed to establish whether the results obtained are caused by differences in cultures, nursing practices or roles of health-care personnel or patients in different European countries.

Coercive procedures and facilities in Swiss psychiatry.

BACKGROUND: Coercive measures in psychiatry,although in many cases effective in violence management and injury reduction, have been criticised from a consumerist point of view. METHOD: A questionnaire regarding coercive facilities and procedures was dispatched to the charge nurses of 86 acute psychiatric admission wards in German speaking Switzerland covering a catchment area of 75% of the Swiss population. RESULTS: 95% of all wards responded rendering the survey representative. The majority of wards have seclusion rooms and 55% of charge nurses perceive seclusion facilities as adequate. Two to twenty staff members are involved in overwhelming dangerous patients and some discontent is expressed at the haphazard fashion in which such events occur. Almost 70% of the wards use a form for reporting, 42 % of wards keep statistics on violent incidents and 17% of wards have access to these data. Of all wards 84% register injections against patients' will, 83% seclusion, and 78% mechanical restraint and a minority of wards register the coercive administration of oral medication, forced nutrition, threats of coercive measures in case of pharmacological non-compliance. DISCUSSION: Isolation, the coercive administration of medicine and restraint techniques are sensitive forms of treatment. Deficits reported by the charge nurses point to the need for enhanced facilities and improved forms of coercion management such as training in the use of mechanical restraints and the overwhelming of dangerous patients. CONCLUSION: The data show considerable differences in the facilities, the use, and the recording of coercive measures in the area under scrutiny.

Perception of aggression among psychiatric nurses in Switzerland.

OBJECTIVE: To identify principal components and patterns in the perception of aggression by psychiatric nurses and to explore relationships between the perception of aggression and personal and workplace characteristics. METHOD: Seven hundred and twenty-nine nurses working in psychiatric inpatient departments of German-speaking Switzerland completed the perception of aggression scale (POAS). Data analysis included factor analysis, group comparisons and multivariate analysis of covariance. RESULTS: Two plausible factors were identified, representing different dimensions in the perception of aggression and accounting for 35% of the variance. Firstly, aggression is perceived as dysfunctional/ undesirable and, secondly, aggression is perceived as a functional/ comprehensible phenomenon. Only minor differences were found in the perception of aggression with regard to personal characteristics or work environment of the nurses. CONCLUSION: Nurses perceive aggression not just as a negative phenomenon. The perception of aggression as measured by POAS is independent of many characteristics expected to be related to the perception of violence, such as grade of education, work experience, etc.

[Frequency of falls in german hospitals].

PURPOSE: So far, there are no statistics on falls by patients in German hospitals. This study records data on the frequency and results of inpatient falls and compares patients who suffered from falls, with the other patients. METHODS: In a prevalence study, we collected data from 3012 patients in 11 hospitals in Berlin and surrounding areas. RESULTS: 3.5 % of all patients fell during their clinical stay. 13 % of the patients who fell suffered a fracture or a joint injury, 20 % another injury while 67 % had no any injuries. The patients who fell were older and more care-dependent than the other patients. Most of the patients fell on geriatric wards. CONCLUSION: Older patients fall more frequently than other patients while in hospital.

Privacy: a review of the literature.

The concept of privacy is used in many disciplines and is recognised as one of the important concepts also in nursing. In this review, a description about the perspectives and dimensions of the concept will be made and empirical studies in the area will be analysed. Perspectives include units experiencing privacy, desired-achieved state, and reactiveness. Dimensions are divided into physical, psychological, social and informational. In the empirical studies, the concept of the privacy has mainly been studied in hospital organisations using the physical dimension. The concept needs further clarification in future.

[The care dependency scale, an assessment instrument].

The Care Dependency Scale, an instrument for the assessment of patients'care dependency, has been translated into German. The scale was tested on (inter-) rater reliability and criterion and construct validity in a hospital population on geriatric, surgical and paediatric wards. As the results of this study were very satisfying, positive recommendations regarding the suitability of the scale for use in the German nursing care situation could be made. However further psychometric testing of the scale is important, for instance in other populations. A final conclusion is that the scale may be used in care settings in German-speaking countries.

The role of CNSs in promoting elderly patients' autonomy in long-term institutions: problems and implications for nursing practice and research.

Autonomy has become an important focus within healthcare. Elderly patients, however, are often denied the right to independent decision making on grounds of incompetence and incapacity. In long-term institutions there are several ways in which the clinical nurse specialist can promote the autonomy of elderly patients. This article provides an overview of the concept of autonomy and discusses some of the problems in its realization in long-term nursing institutions. It also outlines strategies for supporting autonomy in elderly patients and concludes with a discussion of the implications of autonomy to nursing practice and research.

[Knowledge of professional rules of ethics among professional nurses].

During recent years numerous publications on ethical issues appeared in German nursing literature. Nursing theorists repeatedly refer to the Code of Ethics of the International Council of Nursing (ICN). The implementation of codes of ethics is discussed as an indispensable stage within the development of independent nursing ethics. However, it is not clear whether nurses in Germany know about the ICN Code of Ethics or other codes of ethics. The authors' objective is to learn more about how much is known about codes of ethics by practical nurses in four selected hospitals. In addition, it is of interest to know, which advantages nurses might associate with codes of ethics and secondly from which sources nurses prefer to receive ethical education. The study shows that only 25% of the participants know about codes of ethics. It also reveals that further education offered by hospitals or the basic nursing education are seen as the most important source of information related to ethics. The major advantage of codes of ethics seen by the participants is to provide guidance in the decision-making process of ethical dilemma situations in nursing. Secondly the Code of Ethics is regarded as a useful framework to define obligations and rights of nurses in the relationship with patients and relatives. The results of the study indicate that the ICN Code of Ethics is practically unknown among nurses and should be discussed more extensively by practical nurses and nursing theorists.

German nursing students' knowledge of and attitudes to HIV and AIDS: two decades after the first AIDS cases.

German nursing students' knowledge of and attitudes to HIV and AIDS: two decades after the first AIDS case This study describes German nursing students' (n=180) knowledge and attitudes relating to HIV/AIDS, their homophobia level, willingness to care for people with AIDS, and their approach to possible sexual risk behaviours. A questionnaire was used to collect the data (response rate 97.8%). The results indicated that the nursing students had a rather high knowledge level concerning AIDS. However, there were gaps of knowledge, such as regarding AIDS immunopathology or the symptoms of the disease. Single nursing students and those having cared for a person with AIDS had a more thorough knowledge about the disease. In general, the attitudes towards AIDS and people with AIDS were tolerant and positive, and homophobia was only found with a small minority. Students having positive attitudes towards people with HIV/AIDS had less homophobia compared to those having negative attitudes towards persons suffering from AIDS. Those with positive attitudes were more willing to care for patients with HIV/AIDS, while those with a high homophobia level were less willing to do so. In addition, students having a high AIDS knowledge level tended less towards negative attitudes and homophobia than those with a low level of knowledge. The implications of the research for nursing education will be discussed.

An international psychometric testing of the care dependency scale.

In an international study, psychometric properties of the Care Dependency Scale (CDS) were examined by analysing data gathered in Dutch, Canadian, Italian and Norwegian nursing homes. For that purpose, from these countries a convenience sample was developed consisting of 525 patients with dementia. The English, Italian and Norwegian research instruments were translations of the original Dutch CDS. Psychometric evaluations of the CDS were carried out for each country separately as well as for the four countries combined. High alpha coefficients between 0.94 and 0.97 were calculated. Subsequent test-retest and inter-rater reliability revealed moderate to substantial Kappa values. Factor analysis resulted in a one-factor solution. The scalability of the CDS was demonstrated by means of Mokken scale analysis. One of the main outcomes of the cross-cultural comparison was that the findings in the four countries show more similarities than differences, so that the scale can be used appropriately in nursing home practice.

A reliability and utility study of the care dependency scale.

The purpose of this study was to examine the reliability and utility of the Care Dependency Scale (CDS). This 15-item scale has been developed recently for assessing the care dependency of demented or mentally handicapped inpatients. Data for this study were collected from 153 demented and 139 mentally handicapped inpatients. The sample was measured three times. Internal consistency was determined using Cronbach's alpha and ranged from 0.95 to 0.97. Interrater reliability revealed moderate to substantial weighted Kappa statistics between 0.51 and 0.83. Test-retest reliability analysis resulted in substantial weighted Kappas between 0.66 and 0.89. Utility tests also revealed satisfactory results. The findings support the reliability and utility of the CDS.

Predictors of care dependency in Alzheimer's disease after a two-year period.

This paper presents the results from a panel study in the Netherlands of 68 female in-patients with Alzheimer's disease. The main focus of this study was to investigate longitudinal changes and differences in care dependency. Descriptive statistics indicated an increase in almost all 15 features of dependency in a two-year period. A stepwise regression procedure revealed that the loss of social relationships, the loss of the ability to communicate, and the degree of care dependency at entry to the study were the strongest predictors of the follow-up ratings. The pattern of findings reveals that the Care Dependency Scale is sensitive to care dependency increase after a two-year period, and that the scale has utility in establishing longitudinal patterns of care dependency.

Construct validity of the Nursing Care Dependency Scale.

This paper describes the results of a study determining construct validity aspects of the Nursing Care Dependency (NCD) Scale. This 15-item instrument has been developed recently for the assessment of the care dependency of dementia or learning-disabled inpatients. Data was collected for 450 dementia and 203 learning-disabled patients using the NCD instrument. Factor analysis of the NCD instrument resulted in one Factor. With Mokken scale analysis an H-coefficient of 0.75 was found, which implied a strong hierarchical scale. Cronbach's alpha coefficients (0.97) were high enough to use the NCD instrument in clinical practice, at both group and individual levels.
