Abstract Background Depression is a prevalent disorder in chronically ill elderly persons. It may decrease quality of life, and increase functional disability, medical costs, and healthcare utilisation. Because patients may slip into a downward spiral, early recognition and treatment of depression is important. Depression can be treated with antidepressants or psychological interventions; the latter can also be applied by trained paraprofessionals. In this paper, we describe the design of the DELTA study (Depression in Elderly with Long-Term Afflictions). The first objective of the DELTA study is to evaluate the effectiveness and cost-effectiveness of a minimal psychological intervention (MPI) to reduce depression in chronically ill elderly patients. The second objective is to evaluate whether a potential effect of the MPI may differ between types of chronic illnesses. The tailor-made intervention is administered by nurses, who are trained in the principles of cognitive behavioural therapy and self-management. Methods/Design DELTA is a two-armed randomised controlled trial, comparing MPI to usual care. A total number of 180 patients with diabetes mellitus type II (DM) and 180 patients with chronic obstructive pulmonary disease (COPD), who in addition suffer from non-severe depression, will be included in the study. In our study, non-severe depression is defined as having minor depression, mild major depression or moderate major depression. The primary outcome measure is depression using the Beck Depression Inventory. Secondary outcome measures include quality of life, daily functioning, self-efficacy, autonomy, and participation. In the economic evaluation, cost-effectiveness and cost-utility ratios will be calculated. Furthermore, a process evaluation will be carried out. Analyses will include both univariate and multivariate techniques and according to the intention to treat principle. The economic evaluation will be done from a societal perspective and data of the process evaluation will be analysed using descriptive techniques. Discussion A total number of 361 patients has been included in the study. All interventions have been administered and follow-up data will be complete in September 2006. Preliminary results from the process evaluation indicate that patients' satisfaction with the intervention is high. If this intervention proves to be effective, implementation of the DELTA intervention is considered and anticipated.

Given the increasingly heavy workload in the primary health care sector, the option of allocating activities involving the management of chronic diseases to non-physicians has recently come under scrutiny. The purpose of this study was to assess the feasibility of the support provided by non-physicians to general practitioners (GPs) in the early detection of chronic obstructive pulmonary disease (COPD). A convenience sample consisting of 231 patients [40-70 years; >10 pack years (number of packs of cigarettes smoked per day multiplied by the number of years the individual has smoked)] from eight general practices in the Maastricht region in the southern Netherlands, who consulted their GP for reasons unrelated to respiratory diseases, were assessed for their respiratory function. Prior to the first assessment, patients were interviewed about their medical history and symptoms. By taking the results of the lung function measurement as the starting point, the predictive value of medical history and symptoms in the identification of patients at risk for airflow obstruction or of COPD was assessed and compared with findings in the literature. Seventeen patients (7.4%) were diagnosed with COPD, 11 patients (4.8%) with asthma. In addition to age and moderate smoking history, breathlessness and a history of heavy smoking were identified as risk factors for airflow limitation and COPD. Early detection of COPD in primary health care by non-physicians is feasible and should be considered for middle aged, moderate and heavy smokers experiencing breathlessness. [ABSTRACT FROM AUTHOR]

A solution to safeguard high quality diabetes care may be to allocate care to the nurse specialist. By using a one group pretest-posttest design with additional comparisons, this study evaluated effects on patient outcomes of a shared care model with the diabetes nurse as main care-provider for patients with type 2 diabetes in a primary care setting. The shared care model resulted in an improved glycaemic control, additional consultations and other outcomes being equivalent to diabetes care before introduction, with the general practitioner as main care-provider. Assignment of care for patients with type 2 diabetes to nurse specialists seems to be justified. [ABSTRACT FROM AUTHOR]

AIM OF THE STUDY: Assessment of effects on quality of care, in terms of patient outcomes, when tasks in the care for outpatients with stable type 2 diabetes are transferred from internist to nurse specialist and from outpatient clinic to general practice. BACKGROUND: For the management of chronic diseases with a high prevalence and requiring current monitoring, it is suggested that substitution of care may be an appropriate solution to safeguard high quality care. DESIGN AND METHODS: A 12-month nonequivalent control group design was used. General practitioners (GPs) referring diabetes patients to the University Hospital Maastricht were asked to choose for the traditional model or the nurse specialist model. Informed consent was obtained from patients with stable diabetes type 2 attending these practices. All patients received care according to the model chosen by their GP. Identified outcomes were: clinical status, health status, self-care behaviour, knowledge of diabetes, patient satisfaction, and consultation with care-providers. RESULTS: In the control group (n=47) no patients were treated with oral hypoglycaemic agents (OHA) only. The control group was compared with an intervention subgroup (n=52) also without patients receiving OHA only. Clinical data were available for all patients. Patients without complete data from questionnaires had better mean concentration of HbA1c than patients with complete data (P=0.004). The traditional care model and the nurse specialist model achieved equal outcomes, while glycaemic control of patients in the nurse specialist model improved (from 8.6% to 8.3%) but deteriorated in the traditional model (from 8.6% to 8.8%; P-value between groups=0.001). CONCLUSIONS: The model with nurse specialists taking on roles and tasks beyond those traditionally regarded as their remit as well as new ones, is effective for the care of stable diabetic outpatients.

This article investigates whether being a caregiver of an elderly parent and the caregiver's involvement in multiple roles increases distress in middle-aged women. Previous studies assumed that providing care to frail parents causes distress in women, in particular when they have other social roles as well. Longitudinal data were collected within a cohort of middle-aged women (n = 934; n = 743). The acquisition or loss of the caregiver role did not appear to affect levels of distress of middle-aged women, nor did additional roles of caregivers increase distress levels or caregiver role strain. Most distressed were women not performing any major social role, suggesting that the lack of social roles rather than the multiplicity of roles is associated with distress. The caregiver role might even reduce distress when women have very few other roles. Findings are explained in terms of the role scarcity, the role expansion and role accumulation hypotheses of role theory. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To test the usefulness of the Mobility Control subscale (MC scale) of the short version of the Sickness Impact Profile (SIP68) as a simple self-administered questionnaire for screening mobility disorders in a population of independent living elderly. DESIGN: The SIP68-MC scale was compared with the results of one functional test as independent criteria. SUBJECTS AND SETTING: A group of 81 people of 70 years and older was selected from a potential population of over 200 people. All were independent living elderly persons selected from a general practice. Interventions: The short version of the Sickness Impact Profile and questions about falling last year were applied. Three functional tests were carried out: walking 10 metres, get up and sit down in a chair five times and a test for standing balance. A trained observer rated all tests. RESULTS: It is shown that the sensitivity of the MC scale (cut-off point: 1) with the total functional score is 91%, with a relative low specificity (59%). The relationship between the SIP-MC score and falling frequency is significant when there is a falling frequency equal to or more than two times a year. CONCLUSION: It is concluded that the MC scale is a useful test for screening mobility disorders in the elderly. [ABSTRACT FROM AUTHOR]

This study examines to what extent memory capacity is influenced by lifestyle, health or sociodemographic factors. The data were derived from the Maastricht Aging Study (MAAS), a large study carried out in The Netherlands. For the current study 1,673 people aged 24-88 years completed a postal survey on 'Health, Cognition, and Psychosocial factors'. The dependent variable was 'memory capacity' as measured by the Metamemory in Adulthood (MIA) questionnaire. The study shows that age, gender and coping abilities play an important role in influencing the variation in memory capacity. The lifestyle factors of smoking and mental activity also had a significant effect on memory capacity in certain age-specific subgroups. These results suggest that future research should focus on these variables as determinants of cognitive ageing. [ABSTRACT FROM AUTHOR]

This paper describes the results of a detailed evaluation of the intervention process of a multifactorial home visit programme aimed at preventing falls and mobility impairments among elderly persons living in the community. The aim of the study is to provide insight in factors related to the intervention process that may have influenced the effectiveness of this home visit programme. The programme consisted of five home visits performed by a community nurse over a period of 1 year. During the home visits the participants were screened for risk factors potentially influencing falls and mobility. The screening was followed by recommendations, referrals, and other actions aimed at dealing with the hazards observed. Data regarding the intervention process were gathered by means of interviews with nurses and participants, and by means of structured forms and questionnaires administered by the nurses during the intervention period. We conclude that our 1-year multifactorial home visit programme consisting of five home visits is feasible for nurses and participants. Despite this, it seems to be an unsuitable intervention technique to reduce falls and mobility impairments among elderly people at risk. [ABSTRACT FROM AUTHOR]
