Prevalence and risk factors of non-adherence with immunosuppressive medication in kidney transplant patients.

Non-adherence with immunosuppressive regimen is a major risk factor for poor outcome after kidney transplantation. Identifying patients at risk for non-adherence requires understanding the risk factors for non-adherence. This prospective study included a convenience sample of 249 adult kidney transplant patients >1 year post-transplant. Non-adherence was monitored electronically using MEMS(R). Selected socio-economic, therapy-, patient-, condition- and healthcare team-related risk factors for non-adherence were assessed. Period prevalences were expressed as the percent of prescribed doses taken (taking adherence), the percent of correctly dosed days (dosing adherence), the percentage of inter-dose intervals not exceeding 25% of the prescribed interval (timing adherence), and the number of drug holidays per 100 days (no intake for > 48 h if once daily or for > 24 h if twice daily intake). Testing occurred by simple mixed logistic regression analysis. Factors significant after correction for multiple testing were entered into a multiple logistic regression model. Mean taking, dosing, timing adherence, and drug holidays were 98%, 96%, 93%, and 1.1 days, respectively. Non-adherence was associated with lower self-efficacy, higher self-reported non-adherence, no pillbox usage, and male gender. Adherence declined between Monday and Sunday. This study provides a framework for identifying patients at risk for non-adherence and for developing adherence-enhancing interventions.

Heart failure management programmes in Europe.

BACKGROUND: The ESC guidelines recommend that an organised system of specialist heart failure (HF) care should be established to improve outcomes of HF patients. The aim of this study was therefore to identify the number and the content of HF management programmes in Europe. METHOD: A two-phase descriptive study was conducted: an initial screening to identify the existence of HF management programmes; and a survey to describe the content in countries where at least 30% of the hospitals had a programme. RESULTS: Of the 43 European countries approached, 26 (60%) estimated the percentage of HF management programmes. Seven countries reported that they had such programmes in more than 30% of their hospitals. Of the 673 hospitals responding to the questionnaire, 426 (63%) had a HF management programme. Half of the programmes (n = 205) were located in an outpatient clinic. In the UK a combination of hospital and home-based programmes was common (75%). The most programmes included physical examination, telephone consultation, patient education, drug titration and diagnostic testing. Most (89%) programmes involved nurses and physicians. Multi-disciplinary teams were active in 56% of the HF programmes. The most prominent differences between the 7 countries were the degree of collaboration with home care and GP's, the role in palliative care and the funding. CONCLUSION: Only a few European countries have a large number of organised programmes for HF care and follow up. To improve outcomes of HF patients throughout Europe more effort should be taken to increase the number of these programmes in all countries.

To transplant or not? The importance of psychosocial and behavioural factors before lung transplantation.

The gratifying results of lung transplantation in terms of survival and quality of life stimulate the referral of an ever-increasing number of patients with end-stage lung disease. This in turn compounds the organ shortage, which is the limiting factor in the transplantation rate. In the absence of good alternative treatment modalities, an evidence-based pretransplant screening process is a prerequisite to determine which patients will benefit most from transplantation. Within this evidence-based screening process, medical selection criteria are well established. There is a growing awareness that psychosocial and behavioural factors may determine outcome after transplantation as well. This paper reviews the available evidence for psychosocial and behavioural factors in the screening process for lung transplantation. The relation of various factors with post-transplant outcome was explored. Psychosocial characteristics before transplantation consist of 1) anxiety and depression, 2) personality disorders, 3) neurocognitive problems, and 4) lack of social support. Pretransplant behavioural factors include 1) noncompliance with medication, 2) alcohol abuse or dependence, 3) smoking, 4) noncompliance with dietary guidelines, and 5) noncompliance with monitoring of vital parameters and infections. It appears that the lack of rigorous studies limit the feasibility of an evidence-based screening process. Prospective studies are crucial to this further investigation of the relationship between psychosocial and behavioural determinants before transplantation and outcomes after transplantation, in terms of compliance, morbidity, and mortality. Identification of modifiable risk factors for poor outcome before transplantation is a first step in developing interventions.

Nurse specialists in adult congenital heart disease: the current status in Europe.

AIM: Recommendations for the management of adults with congenital heart disease indicate that specialist referral centres should employ nurse specialists who are trained and educated in the care for these patients. We surveyed the involvement, education and activities of nurse specialists in the care for adults with congenital cardiac anomalies in Europe. METHODS: The Euro Heart Survey on Adult Congenital Heart Disease has previously showed that 20 out of 48 specialist centres (42%) have nurse specialists affiliated with their programme. Fifteen of these 20 centres (75%) validly completed a web-based survey tool. RESULTS: Specialist centres had a median number of 2 nurse specialists on staff, corresponding with 1 full-time equivalent. In most centres, the nurse specialists were also affiliated with other cardiac care programmes, in addition to congenital heart disease. The involvement of nurse specialists was not related to the caseload of inpatients and outpatient visits. Physical examination was the most prevalent activity undertaken by nurse specialists (93.3%), followed by telephone accessibility (86.7%), patient education (86.7%), co-ordination of care (73.3%), and follow-up after discharge (73.3%). Patient education covered mainly prevention and prophylaxis of endocarditis (100%), cardiovascular risk factors (92.3%), sport activities (92.3%), the type and characteristics of the heart defect (92.3%), the definition and aetiology of endocarditis (84.6%), cardiac risk in case of pregnancy (84.6%), and heredity (84.6%). Two third of the nurse specialists were involved in research. CONCLUSION: This survey revealed gaps in the provision of care for these patients in Europe and demonstrated that there is room for improvement in order to provide adequate chronic disease management. The results of this study can be used by individual hospitals for benchmarking.

Is the severity of congenital heart disease associated with the quality of life and perceived health of adult patients?

OBJECTIVE: To explore whether the severity of congenital heart disease is associated with the quality of life and perceived health status of adult patients. DESIGN: Descriptive, cross sectional study. SETTING: Adult congenital heart disease programme in one tertiary care centre in Belgium. PATIENTS: 629 patients (378 men, 251 women) with a median age of 24 years. MAIN OUTCOME MEASURES: Disease severity was operationalized in terms of initial diagnosis (classification of Task Force 1 of the 32nd Bethesda Conference), illness course (disease severity index), and current functional status (New York Heart Association (NYHA) class, ability index, congenital heart disease functional index, and left ventricular ejection fraction). Quality of life was measured by a linear analogue scale, the satisfaction with life scale, and the schedule for evaluation of individual quality of life. Perceived health status was also assessed with a linear analogue scale. RESULTS: Scores derived from the disease severity classification systems were weakly negatively associated with quality of life and health status, ranging from -0.05 to -0.27. The NYHA functional class and ability index were consistently associated with quality of life and perceived health. CONCLUSIONS: This study showed that the severity of congenital heart disease is marginally associated with patients' quality of life and perceived health. Functional status was more related to patients' assessment of their quality of life than was the initial diagnosis or illness course.

Meeting the challenges for gerontological nursing in Europe: The European Nursing Academy for Care of Older persons (ENACO).

In order to support the urgent need for proactive and targeted investments in care for older persons a group of geriatric nurse specialists from different European countries convened in Leuven (Belgium) in November 2002 to launch the European Nursing Academy for Care of Older persons (ENACO). The mission of ENACO is to enhance outcomes of older persons and their caregivers through strengthening gerontological clinical nursing care, education, research and health policy within an interdisciplinary context. Specific objectives of ENACO are: 1) providing up-to-date education and training by "teaching the teachers". More specifically, the target groups are master's prepared nurses specialized in gerontology who can contribute and guide the development of gerontological/geriatric nursing care in their own country; 2) developing a core curriculum for basic gerontological nursing education in Europe and; 3) developing an European network of gerontological nursing expertise. More specifically, a web page providing opportunities for interactive communication as well as a mentoring program will be developed for nurses interested in the deepening and fine-tuning of their professional experience in care for older persons. The fact that care for older persons is high on the European agenda, the collaboration with the European Academy for Medicine of Ageing (EAMA), and other professional organizations in Europe and other parts of the world, are promising elements in the development of ENACO.

[Developing and establishing an expanded and more comprehensive HIV/AIDS nursing practice].

Developing and establishing an advanced nursing practice is an essential step toward future-oriented nursing care. An action research process was initiated to establish advanced nursing practice at the HIV clinic of the outpatient department at the University Hospital Basel with the goal to offer advanced nursing care to patients. Participatory action research allows generating knowledge about a social system while at the same time tempts to promote social change. The most important goal is to constantly analyse, improve, and evaluate nursing care for patients and family caregivers. Advanced nursing practice in HIV/AIDS is based on solid knowledge regarding the illness and current therapies. Central concepts are caring, clinical experiences, evidence based practice, and patient preferences. Through a systematic step-by-step process, the nurses at the HIV clinic are being better educated and more experienced in these concepts. An essential aspect of advanced nursing practice is the specialization of each nurse in a self selected topic within HIV/AIDS care. These nurses now offer new services such as medication management and adherence support, health maintenance and prevention, and symptom management. This ongoing process of learning while establishing advanced nursing practice in HIV/AIDS, enables the nurses to face future changes in health care in a proactive way.

A pilot study of expenditures on, and utilization of resources in, health care in adults with congenital heart disease.

BACKGROUND: Congenital cardiac disease may be a chronic condition, necessitating life-long follow-up for a substantial proportion of the patients. Such patients, therefore, are often presumed to be high users of resources for health care. Information on utilization of resources in adults with congenital heart disease, however, is scarce. METHODS: This retrospective pilot study, performed in Belgium, investigated 192 adults with congenital heart disease to measure the annual expenditures and utilization of health care and compared the findings with data from the general population. We also sought to explore demographic and clinical parameters as predictors for the expenditures. RESULTS: Hospitalization was documented in 20.3% of the patients, with a median length of stay of 5 days. The overall payment by health insurance associations in 1997 was 1794.5 ECU per patient, while patients paid on average 189.5 ECU out-of-pocket. For medication, the average reimbursement and out-of-pocket expenses were estimated at 78 ECU and 20 ECU, respectively. Expenditures for patients with congenital heart disease were considerably higher than the age and gender-corrected expenditures for the general population (411.7 ECU), though this difference was accounted for by only one-eighth of the cohort of those with congenital heart disease. In general, higher expenditures were associated with abnormal left ventricular end-diastolic diameter, female gender, functional impairment and higher age, although the explained variance was limited. CONCLUSION: Our study has provided pilot data on the economic outcomes for patients with congenital heart diseases. We have identified parameters that could predict expenditure, but which will have to be examined in future research. This is needed to develop guidelines for health insurance for those with congenital heart diseases.

[Visions for the future--nursing as a profession in German-speaking Swiss health care].

Social, scholarly, and technical changes and changes in health politics have a lasting influence on the nursing profession. The development of nursing science programs can be seen in this context and institutions, which offer educational programs for nurses, have to orient them toward the new demands of the profession. Up to now in the German-speaking realm, published data, which describe the changes the nursing profession can expect, have not been available, nor have possible future fields of activity of nursing been examined. In order to close this gap, a group of opinion leaders and experts in nursing in German-speaking Switzerland were studied. Eighty-one people were surveyed by means of a questionnaire, and ten people were interviewed in-depth. The results reflect the visions and perspectives of the nursing profession of the future in German-speaking Switzerland. The expectation is that nursing should deal increasingly with sociopolitical changes and that the main issues of nursing with regard to type of client and locations where care is given will change. A re-orientation toward strengthening professional identity is called for in the following areas: involvement in determining and shaping decisions in politics and health politics; taking entrepreneurial initiatives; building clinical practice on caring, patient preferences, and evidence; making professional training and continuing education clinically-oriented as well as the development and the establishment of nursing science. Through a re-orientation, nursing should be better able to meet the challenges, which it faces because of health and social problems in the population. A great discrepancy exists between the expectations for nursing in the future and present reality. The challenge will be to see whether it will be possible to close the gap between visions and reality by means of training, continuing education, and changes in clinical practice.

A nurse-led interdisciplinary intervention program for delirium in elderly hip-fracture patients.

OBJECTIVES: To develop and test the effect of a nurse-led interdisciplinary intervention program for delirium on the incidence and course (severity and duration) of delirium, cognitive functioning, functional rehabilitation, mortality, and length of stay in older hip-fracture patients. DESIGN: Longitudinal prospective before/after design (sequential design). SETTING: The emergency room and two traumatological units of an academic medical center located in an urban area in Belgium. PARTICIPANTS: 60 patients in an intervention cohort (81.7% females, median age = 82, interquartile range (IQR) = 13) and another 60 patients in a usual care/nonintervention cohort (80% females, median age = 80, IQR = 12). INTERVENTION: (1) Education of nursing staff, (2) systematic cognitive screening, (3) consultative services by a delirium resource nurse, a geriatric nurse specialist, or a psychogeriatrician, and (4) use of a scheduled pain protocol. MEASUREMENTS: All patients were monitored for signs of delirium, as measured by the Confusion Assessment Method (CAM). Severity of delirium was assessed using a variant of the CAM. Cognitive and functional status were measured by the Mini-Mental State Examination (MMSE) (including subscales of memory, linguistic ability, concentration, and psychomotor executive skills) and the Katz Index of activities of daily living (ADLs), respectively. RESULTS: Although there was no significant effect on the incidence of delirium (23.3% in the control vs 20.0% in the intervention cohort; P =.82), duration of delirium was shorter (P =.03) and severity of delirium was less (P =.0049) in the intervention cohort. Further, clinically higher cognitive functioning was observed for the delirious patients in the intervention cohort compared with the nonintervention cohort. Additionally, a trend toward decreased length of stay postoperatively was noted for the delirious patients in the intervention cohort. Despite these positive intervention effects, no effect on ADL rehabilitation was found. Results for risk of mortality were inconclusive. CONCLUSIONS: This study demonstrated the beneficial effects of an intervention program focusing on early recognition and treatment of delirium in older hip-fracture patients and confirms the reversibility of the syndrome in view of the delirium's duration and severity.

Profiles of patients who experienced a late acute rejection due to nonadherence with immunosuppressive therapy.

The purpose of this study was to determine the significance and patient profiles of nonadherence with immunosuppressive therapy in the etiology of late acute rejections (LARs), more than 1 year after heart transplantation. Nonadherence was assessed in 101 heart transplant recipients (14 females, 87 males) with a median age of 56 (Q1=50; Q3=61) and a median posttransplant status of 3 (range, 1-6) years, using electronic event monitoring and self-report. The influence of depression, perceived self-efficacy, knowledge, perceived health, symptom frequency and distress, perceived social support, and adherence with outpatient appointments on medication nonadherence was examined. Ten LARs occurring in six patients were observed. Nine of the rejections, emerging in five patients, appeared to be caused by medication nonadherence. Nonadherence with immunosuppressive therapy is a major risk factor in the etiology of LAR. Patient profiles allow the identification of patients at risk.

What do adult patients with congenital heart disease know about their disease, treatment, and prevention of complications? A call for structured patient education.

OBJECTIVE: To assess how much adults with congenital heart disease understand about their heart defect, its treatment, and the preventive measures necessary to avoid complications. DESIGN: Descriptive, cross sectional study. SETTING: Adult congenital heart disease programme in one tertiary care centre in Belgium. PATIENTS: 62 adults with congenital heart disease (47 men; 15 women), median age 23 years. MAIN OUTCOME MEASURES: Patients' knowledge was assessed during an outpatient visit using the Leuven knowledge questionnaire for congenital heart diseases, a 33 item instrument developed for this study. RESULTS: Patients had adequate knowledge (> 80% correct answers) about their treatment, frequency of follow up, dental practices, occupational choices, appropriateness of oral contraceptives, and the risks of pregnancy. Knowledge about the name and anatomy of the heart defect, the possibility of recurrent episodes of endocarditis during their lifetime, and the appropriateness of different physical activities was moderate (50-80% correct answers). There was poor understanding (< 50% correct answers) about the reasons for follow up, the symptoms of deterioration of the heart disease, the definition, characteristics, and risk factors of endocarditis, the impact of smoking and alcohol on the heart disease, the hereditary nature of the condition, and the suitability of intrauterine devices as contraceptives. CONCLUSIONS: Adults with congenital heart disease have important gaps in their knowledge about their condition. The results of this study can be used as a basis for developing or optimising structured educational interventions to enhance patients' health behaviour.

Psychosocial and behavioral selection criteria for solid organ transplantation.

An evidence-based selection process for organ transplantation may be a valuable approach to improve posttransplant outcomes. This paper reviews state-of-the-art psychosocial and behavioral selection criteria and assesses their validity in view of predicting outcomes after transplantation. Psychosocial factors addressed are psychiatric disorders, mental retardation, irreversible cognitive dysfunction, and lack of social support. Behavioral selection criteria discussed are alcoholism, smoking, drug abuse, and obesity. This review reveals that the evidence concerning these selection criteria in scarce. There is a definite need for more longitudinal research to strengthen the scientific basis of the psychosocial and behavioral dimension of transplantation.

Psychometric properties of the "Modified Transplant Symptom Occurrence and Symptom Distress Scale".

The aim of this study was to assess key aspects of the reliability and validity of the "Modified Transplant Symptom Occurrence and Distress Scale," an instrument measuring symptom experience associated with side effects of triple drug therapy in transplant patients. This cross-sectional, comparative study included 108 renal transplant recipients (61% men; 39% women) with a median age of 47 years and a median posttransplant status of 5.5 years. Renal transplant patients were matched by age and gender with 108 healthy control persons not taking immunosuppressive drugs. Content validity, construct validity and discriminant validity of the instrument were substantiated. Internal consistency reliability was not useful to assess in this instrument, as the conditions for calculating Cronbach's alpha were not satisfied. These findings document the validity of the "Modified Transplant Symptom Occurrence and Symptom Distress Scale" as an instrument to measure symptom experience with immunosuppressive drugs.
