Training needs analysis is considered essential to professional and organizational development, for continuing education and for incorporation into professional practice. Increasingly, nurses are encouraged to develop their health promotion role. Despite this there has been relatively little research in Scotland into the health promotion role of the hospital nurse. This study describes the results of a health promotion training needs analysis undertaken on qualified, hospital-based nurses in Lanarkshire, Scotland. Information on the nurses' current health promotion practices, their attitudes and beliefs, their views on role development and priorities for further training were collated, analysed and discussed within the framework of the Health Action Model. This model was originally designed to assist understanding of the gap that exists between an individual intention to act and the eventual health action. However, in this study the ways in which ‘cognitive factors’ (knowledge and beliefs) and ‘motivational factors’ (considering values, attitudes and drives) and pressures from social norms and significant others assisted in the understanding of the nurse's orientation to, and beliefs about, health promotion practice. Fifty-seven per cent of nurses in the study considered health promotion activities to be emerging in clinical care and 4% considered them to be advanced. The interest respondents have in role development and the further integration of health promotion activities into nursing practice was explored by ascertaining the nurses' attitudes and beliefs about their own health promotion role. Of 107 respondents, a majority 72 (67%) agreed health promotion interventions to be an important function of the nurse with 29 (27%) strongly agreeing (n=107). Sixty per cent stated they would be interested in developing their role and 30% were very strongly interested. Recommendations are therefore made for future planning and development strategies for the health promotion role of hospital nurses.  相似文献

Studies on the effectiveness of pain management have uniformly concluded that health care providers underestimate or undertreat pain. In the emergency department (ED) in which this study was conducted, physicians receive formal didactic and bedside teaching on pain recognition and management in order to heighten the awareness of patient's need for pain control. The purpose of this study was to determine if this outpatient pain management of patients with acute, painful conditions is better than that reported in the medical literature. In this prospective study, 110 adult patients who had an acute, painful diagnosis were telephoned 48 hours after discharge from the ED and asked if they felt their pain at home was well controlled. Patient satisfaction with pain control was higher (91%) than that reported in the medical literature. Also, pain medication was provided more frequently by this study's ED (95%). Education on pain awareness and treatment is a way to improve pain management.  相似文献

Such research evidence as exists on effective drug strategies in prevention and education draws attention to the importance of involving parents along with other community agencies and school governors. Much depends nevertheless on the way in which 'involvement' is interpreted and the assumptions that are made about parents' knowledge of drugs and drug education as well as their attitudes to drug issues. As the age of initial experimentation and contact with drugs continues to fall, the importance of enskilling parents to support drug education programmes for 5 year olds and upwards continues to rise. This paper reports the first wide ranging survey of parents' knowledge of drugs and drug issues across an entire English county embracing younger as well as older children. The need for more coordinated, informed and systematic guidance to parents is established.  相似文献

Drug related hospital admissions   总被引:13,自引:0,他引:13  
Summary As part of a high-intensity monitoring study of drug events as the cause of admission to departments of internal medicine, the effect of an educational intervention programme was studied. Two departments were included, one specialising in geriatrics and one that received patients by non-selected referral. The series consisted of 607 consecutive admissions studied before and 703 after the intervention. The drug events considered were adverse drug reactions and dose-related therapeutic failures, mainly due to non-compliance.A modest, statistically non-significant decrease in drug related hospital admissions (DRH) was seen, from 14% before to 13% after the intervention period. However, DRHs classified as definitely avoidable showed the significant decrease of 83%.There was no apparent relationship between the topics selected for the intervention programme and changes in the pattern of DRHs. No relationship between alterations in sales data and hospital admissions caused by a given drug could be demonstrated. A blinded external evaluation of case abstracts did not disclose any significant shift in the investigators' assessments.The intervention may have had an non-specific effect on avoidable DRHs.  相似文献

The purpose of this study was to assess the degree of consistency in student ratings of teacher effectiveness during the first year of medical school. Student ratings of teaching effectiveness represent a commonly used source of information that enters into the academic decision-making process. In medical school, student evaluations often represent a major source of information that is used in promotion and tenure decisions. It is essential that the precision of such ratings be ascertained so that decision-makers will know how much confidence to place in this source of information on teaching effectiveness. In this study, each member of a first-year medical school class was randomly assigned a two-digit identification number at the beginning of the spring semester, 1986. As the semester progressed students were asked to evaluate each full-time teacher in three major courses. Multiple instructors were utilized in each course (n = 10). Each teacher was evaluated immediately after lectures during the first (T1) and second (T2) halves of the course. Students evaluated the teacher a third time (T3) as part of the end-of-semester overall course evaluation. The teachers were evaluated on a short eight-item Likert-type scale that identified several key indicators of effective teaching. Students attached their anonymous identification numbers to individual ratings so that their responses could be matched in the analysis. The results indicate that medical students are only moderately consistent in the extent to which they evaluate teachers. This inconsistency varied by course and by instructors within courses.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

India is called the land of villages. In 1951, 82.7% of the Indian population lived in rural areas. Sanskritisation and urbanisation have changed the pattern. It is expected that by the year 2020 this percentage would come down to 55%. These villagers are relocating in urban slums. Thus from the rehabilitation point of view both problems pose challenges. An Indian village community is a political, economic and cultural unit. At the urban slum area at Malwani and in small villages near Juchandra, community rehabilitation programmes were found to be most pragmatic. Community education and preventive occupational therapy are found to be essential steps in rural rehabilitation. Therapists have to work on ‘disability, attitude and beliefs’ and change the behaviour to deal with the grass root (basic) causes. It is felt that for longer sustainment, community-based rehabilitation should originate within the community. Heath professionals must recognise the capabilities of individuals within the support structure of the family and community, while helping individuals to improve the quality of their lives.  相似文献

Teaching of medical ethics   总被引:1,自引:0,他引:1  
Teaching medical ethics in Manchester within the introductory course of obstetrics and gynaecology is a joint activity with the Centre for Social Ethics and Policy. This interdisciplinary teaching has evolved through lecture sessions with small-group discussions dealing with topics of interest in human reproduction. The small-group discussion have been replaced by an open debate conducted by the students. Their own involvement and participation and an exposure to the disciplines of the humanities has broadened their approach to different ways of problem-solving of these real issues.  相似文献
