Transfer of care for outpatients with stable chronic obstructive pulmonary disease from respiratory care physician to respiratory nurse--a randomized controlled study.

OBJECTIVES: To assess effects on patient outcomes when care for patients with stable chronic obstructive pulmonary disease (COPD) is transferred from respiratory care physician to respiratory nurse. METHODS: A randomized controlled trial was used with a follow-up period of 9 months. Of 720 patients from the respiratory outpatient clinic of the general and teaching hospital in Alkmaar (The Netherlands), 187 were eligible for randomization and gave informed consent. Ninety-three patients received care from the nurse, and 87 received usual care. Outcomes measured were: clinical parameters, health status, self-care behaviour (including knowledge), patient satisfaction, and consultations with key care providers. RESULTS: The respiratory nurse reported more consultations than the respiratory care physician [mean (standard deviation)]: number of consultations 3.1 (0.7) by nurse and 2.0 (0.9) by physician (p = 0.007). Patients cared for by the nurse showed worsening in mean forced vital capacity [-5.5% (13.3%) v. +2.9% (18.2%) with physician; p = 0.004], and no difference in self-assessed condition, while improvements were found for subjective knowledge (p = 0.017), self-assessed rate for coping with COPD (p = 0.045), overall satisfaction (p = 0.003), and the majority of individual indicators of satisfaction. Groups showed no differences for forced expiratory volume in 1 s, body mass index, smoking status, health status, objective knowledge, other items of self-care behaviour, and consultations with key care providers. DISCUSSION: Assignment of care for outpatients with stable COPD to the respiratory nurse, working under a protocol, seems to be justified in terms of patient outcomes.

Effectiveness and cost-effectiveness of a minimal psychological intervention to reduce non-severe depression in chronically ill elderly patients: the design of a randomised controlled trial [ISRCTN92331982].

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.

[More social exclusion of chronically ill patients with lower incomes]. / Meer sociale uitsluiting van chronisch zieken bij een lager inkomen.

OBJECTIVE: To determine whether income is connected with the variation in the social exclusion of chronically ill patients. DESIGN: Descriptive. METHOD: In 223 chronically ill patients that had been detected via patients' associations, general practitioners and outpatient clinics, a structured interview was administered during a home visit 4 times during a period of 7 months (October 2003-April 2004). Due to dropouts, the actual number of patients interviewed at each of the 4 times was 223, 176, 143 and 105, respectively. Social exclusion was measured with the aid of the 'Autonomy outside the home' subscale of the 'Impact on participation and autonomy' questionnaire. The possible total score varied from 5 (little social exclusion) to 25 (much social exclusion). In order to explain a possible effect of income, various other patient characteristics were added to the analysis model: type of primary disease (rheumatism, multiple sclerosis, pulmonary emphysema, other), duration of the primary disease, comorbidity, educational level, whether or not the patient was employed or engaged in volunteer work, whether or not the patient lived together with a partner, the self-rated health, physical functioning, social functioning, mental functioning, and the subjective pain. The data were analysed by means of multilevel repeated regression analysis. RESULTS: A low income was associated with social exclusion at all 4 times of measurement. The regression coefficient of income was -1.47 (95% CI: -2.28- -0.65), indicating that the score on the scale for social exclusion decreased by 1.47 for every euro 544,- (= 1 x SD) increase in net monthly income. This relationship could not be explained by the other patient characteristics, not even by a low educational level. CONCLUSION: The supportive care intended for the prevention of social exclusion of chronically ill patients should be concentrated sufficiently on those who have too little income to organise such care for themselves.

Scaling the sickness impact profile using item response theory: an exploration of linearity, adaptive use, and patient driven item weights.

BACKGROUND AND OBJECTIVE: The objective of the study was to enhance the clinical interpretation and practicality of the widely used comprehensive Sickness Impact Profile. METHOD: Item Response Theory (extension of the Rasch model) was used to calibrate the severity of the SIP items, to assess item bias and to construct equally severe short forms of the SIP that can be used interchangeably. The scores of 1507 subjects were analyzed. RESULTS: Of the 127 SIP items, 82 items fitted the extended Rasch model, i.e., the observed proportions of sickness level groups endorsing the items corresponded to the proportions expected by the model. The item severity hierarchy allowed a more straightforward interpretation of the calibrated SIP-82 scores. Some items showed bias in age, gender, or diagnosis groups. The equivalent short forms agreed sufficiently well with the calibrated SIP-82 item pool to be used interchangeably. We observed a moderate correlation between the original SIP item severity weights and the Rasch item severity calibrations (r=0.53). CONCLUSION: The interpretability and practicality of the SIP was enhanced by the IRT calibration. Using the item calibrations, short forms can be assembled that can be used interchangeably.

Applying low disease activity criteria using the DAS28 to assess stability in patients with rheumatoid arthritis.

OBJECTIVES: To examine whether low disease activity criteria using the disease activity score (DAS28) can be applied to identify a reasonably large number of patients with stable low disease activity of rheumatoid arthritis (RA) over a six month period, with the ultimate intention of including these patients in a substitution based, shared care model. Additionally, to assess the reliability of the DAS28 for selecting patients with stable disease from an outpatient population. METHODS: Patients regularly seen at the rheumatology outpatient department of the university hospital Maastricht, were invited for assessment of the stability of their RA. The shared care model was intended to provide care to patients with stable, low disease activity of RA by nurse specialists. For this, patients underwent assessments using the DAS28 criteria at entry and three and six months later. Test-retest reliability was assessed for composing measures as well as for the DAS28. RESULTS: Of the 97 outpatients included, one third (31 patients) did not complete the study. Patients with missing data were older and assessed their disease activity as greater than patients with complete data. Applying the low disease activity criteria to assess stability over a period of six months (DAS28(T0)

The nurse specialist as main care-provider for patients with type 2 diabetes in a primary care setting: effects on patient outcomes.

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.

A risk model for the prediction of recurrent falls in community-dwelling elderly: a prospective cohort study.

The object of this article was to determine the predictive value of risk factors for recurrent falls and the construction of a fall risk model as a contribution to a mobility assessment for the identification of community-dwelling elderly at risk for recurrent falling in general practice. The design was a prospective cohort study (n = 311). There were four primary health care centers. A sample stratified on previous falls, age, and gender of community-dwelling elderly persons aged 70 years or over (n = 311) was taken from the respondents to a mail questionnaire (n = 1660). They were visited at home to assess physical and mental health, balance and gait, mobility and strength. A 36-week follow-up with telephone calls every 6 weeks was conducted. Falls and fall injuries were measured. During follow-up 197 falls were reported by 33% of the participants: one fall by 17% and two or more falls by 16%. Injury due to a fall was reported by 45% of the fallers: 2% hip fractures, 4% other fractures, and 39% minor injuries. A fall risk model for the prediction of recurrent falls with an area under the curve (AUC) of 0.79, based on logistic regression analysis, showed that the main determinants for recurrent falls were: an abnormal postural sway (OR 3.9; 95% Cl 1.3-12.1), two or more falls in the previous year (OR 3.1; 95% Cl 1.5-6.7), low scores for hand grip strength (OR 3.1; 95% Cl 1.5-6.6), and a depressive state of mind (OR 2.2; 95% CI 1.1-4.5). To facilitate the use of the model for clinical practice, the model was converted to a "desk model" with three risk categories: low risk (0-1 predictor), moderate risk (two predictors), and high risk (> or =3 predictors). A fall risk model converted to a "desk model," consisting of the predictors postural sway, fall history, hand dynamometry, and depression, provides added value in the identification of community-dwelling elderly at risk for recurrent falling and facilitates the prediction of recurrent falls.

Substitution model with central role for nurse specialist is justified in the care for stable type 2 diabetic outpatients.

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.

The construction of a patient record-based risk model for recurrent falls among elderly people living in the community.

BACKGROUND: Predictive models of fall risk in the elderly living in the community may contribute to the identification of elderly at risk for recurrent falling. OBJECTIVES: Our aim was to investigate occurrence, determinants and health consequences of falls in a community-dwelling elderly population and the contribution of data from patient records to a risk model of recurrent falls. METHODS: A population survey was carried out using a postal questionnaire. The questionnaire on occurrence, determinants and health consequences of falls was sent to 2744 elderly persons of 70 years and over, registered in four general practices (n = 27 000). Data were analysed by bivariate techniques and logistic regression. RESULTS: A total of 1660 (60%) responded. Falls (> or =1 fall) in the previous year were reported by 44%: one-off falls by 25% and recurrent falls (> or =2 falls) by 19%. Women had significantly more falls than men. Major injury was reported by 8% of the fallers; minor injury by 49%. Treatment of injuries was by the GP in 67% of cases. From logistic regression, a risk model for recurrent falls, consisting of the risk factors female gender, age 80 years or over, presence of a chronic neurological disorder, use of antidepressants, problems of balance and sense organs and complaints of muscles and joints was developed. The model predicted recurrent falls with a sensitivity of 64%, a specificity of 71%, a positive predictive value of 42% and a negative predictive value of 86%. CONCLUSION: A risk model consisting of six variables usually known to the GP from the patient records may be a useful tool in the identification of elderly people living in the community at risk for recurrent falls.

Effects on quality of care for patients with NIDDM or COPD when the specialised nurse has a central role: a literature review.

Chronic care has to be organised in a way that care from any one caregiver is linked up to that provided by others so that disturbing gaps, contradictions and overlaps are avoided. In the search for the most effective and efficient combination of health professionals to deliver care to chronic patients, the role of the specialised nurse has become important. This article reviews a Medline search for publications about the effects of models of care for patients with NIDDM or COPD in which the specialised nurse has a central role. Main features of the models are identified and related to expected and statistically significant effects. In this young domain of effect evaluation ten publications met our criteria. Depending on the division of tasks between care providers, improvements are seen in self-care, quality of life and patient satisfaction, as well as increased medical consumption. More methodologically suitable evaluations with the use of only valid measures are needed.

Effects of a programme of multifactorial home visits on falls and mobility impairments in elderly people at risk: randomised controlled trial.

OBJECTIVE: To evaluate whether a programme of multifactorial home visits reduces falls and impairments in mobility in elderly people living in the community. DESIGN: Randomised controlled trial with 18 months of follow up. SETTING: Six general practices in Hoensbroek, the Netherlands. PARTICIPANTS: 316 people aged 70 and over living in the community, with moderate impairments in mobility or a history of recent falls. INTERVENTION: Five home visits by a community nurse over a period of one year. Visits consisted of screening for medical, environmental, and behavioural factors causing falls and impairments in mobility, followed by specific advice, referrals, and other actions aimed at dealing with the observed hazards. MAIN OUTCOME MEASURES: Falls and impairments in mobility. RESULTS: No differences were found in falls and mobility outcomes between the intervention and usual care groups. CONCLUSION: Multifactorial home visits had no effects on falls and impairments in mobility in elderly people at risk who were living in the community. Because falls and impairments in mobility remain a serious problem among elderly people, alternative strategies should be developed and evaluated.

Effects of preventive home visits to elderly people living in the community: systematic review.

OBJECTIVE: To assess the effects of preventive home visits to elderly people living in the community. DESIGN: Systematic review. SETTING: 15 trials retrieved from Medline, Embase, and the Cochrane controlled trial register. MAIN OUTCOME MEASURES: Physical function, psychosocial function, falls, admissions to institutions, and mortality. RESULTS: Considerable differences in the methodological quality of the 15 trials were found, but in general the quality was considered adequate. Favourable effects of the home visits were observed in 5 out of 12 trials measuring physical functioning, 1 out of 8 measuring psychosocial function, 2 out of 6 measuring falls, 2 out of 7 measuring admissions to institutions, and 3 of 13 measuring mortality. None of the trials reported negative effects. CONCLUSIONS: No clear evidence was found in favour of the effectiveness of preventive home visits to elderly people living in the community. It seems essential that the effectiveness of such visits is improved, but if this cannot be achieved consideration should be given to discontinuing these visits.

Preventing falls and mobility problems in community-dwelling elders: the process of creating a new intervention.

Mobility impairments and the consequences of falls can have a considerable impact on community-dwelling elders' autonomy and quality of life. This article describes the development and implementation of a falls and mobility intervention that features preventive home visits by public health nurses; the study accompanying the intervention also is presented. This article offers practical guidelines to health professionals who are considering, developing, implementing, and testing new interventions aimed at the prevention of falls and mobility problems in this population.

Multigenerational caregiving and well-being: distress of middle-aged daughters providing assistance to elderly parents.

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.

Screening for mobility disorders by the Mobility Control subscale of the short version of the Sickness Impact Profile.

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.

How ageing and social factors affect memory.

OBJECTIVES: To explore the relationships between lifestyle and memory, and determine whether social factors influence memory. METHODS: the relationship between memory and lifestyle was examined in 497 adults aged 25-80 years, using the Mectamemory in Adulthood questionnaire. We asked about sports activity and perceived activity, participation in voluntary organizations and social contacts. RESULTS: Activity and frequent contact with friends and family were related to higher memory capacity scores. Those with higher capacity scores were also younger, had better health and a stronger internal locus of control. In contrast, people with higher anxiety scores had more symptoms and less education, and were more externally oriented. CONCLUSIONS: people who consider themselves socially and physically active also consider their memory capacity to be good and are less anxious about their memory than less socially and physically active people. Perceived memory change appears to be predominantly influenced by ageing, whereas memory capacity and memory anxiety are more influenced by social factors.

Impact of gait problems and falls on functioning in independent living persons of 55 years and over: a community survey.

In a cross-sectional, population-based study among community-dwelling persons of 55 years and over the incidence of falls, risk indicators for falls, specifically age, and the impact of gait problems, falls and other risk factors on functioning was determined. A randomly age-stratified sample (n = 655) was taken from all independent living persons of 55 years and over (n = 2269) and registered in a primary health care centre. They received a mail questionnaire concerning demographic data, history of falls and injuries due to falls, physical and mental health status, gait problems, functional status, including social activities. The response rate was 62% (n = 405). Of the subjects aged 55 years and of those aged 65 years and over, 25% and 31% respectively fell at least once in the previous year. Half of the people reporting falls fell more than once. Serious injury occurred in 9% of the fallers, with 4% fractures. There is a significant association between falling and age and, even more clearly, between gait problems and age. The main risk factors of single and recurrent falls were female gender, physical health status and gait problems. Logistic regression analysis reveals that the main determinants of falling in general are gait problems and female gender and, of recurrent falling female gender, physical complaints and gait problems. Falls have some negative effect on functioning, i.e. mobility range and social activities, but this is overshadowed by mental status indicators and gait problems.

Use of care by home-dwelling stroke patients during three years following hospital discharge.

Of 82 stroke survivors who had been discharged from hospital, 49 were still living at home after a three-year period. Thirty-three of these patients formed the population of the present study of the use of care at home. Sixty-one percent had received professional care and 88% had received family care. Although their overall functional status indicated only mild handicaps, after three years patients still reported a large number of disabilities and problems. The average weekly amount of family care was 37 h, and many family carers experienced a high burden of care and had emotional problems coping with the patients' disabilities. Concerning factors related to the use of care, in spite of the relatively small number of study patients, some interesting hypotheses can be advanced.

[Nursing home day-care: a growing function for a rather stable patient group]. / Verpleeghuisdagbehandeling: een groeiende functie voor een tamelijk vast omschreven doelgroep.

This article is a descriptive study of the characteristics of nursing home day-care patients in the Netherlands in 1995 at first admission and at discharge. Data were derived from the National Nursing Home Registration System (SIVIS), in which in 1995 over 85% of Dutch nursing homes participated. Newly admitted day-care patients are characterized by high age (89% older than 65 years), a distribution with (only!) 9% more women than men and a morbidity pattern of chronic somatic (cerebrovascular disease 45%) and psychogeriatric (dementia 80%) disorders. This morbidity pattern was associated with a considerable degree of disability, in particular regarding the activities of daily living and mobility. Most patients (78%) come from their own homes. The average length of stay from admittance to discharge, for both somatic and psychogeriatic day-care patients was nine months. For about 10% of the somatic patients and 40% of the psychogeriatic ones ambulatory day-care resulted in (subsequent) admission to the nursing home itself. In the last decade nursing home day-care capacity has increased rapidly and parallel to this also the number of day-care patients. Remarkably the average level of disability and the average period of treatment of nursing home day-care patients has remained approximately the same in this period.

Women of a middle generation and parent care.

This article addresses women who are caring for both parents and children, the so called sandwich generation or women-in-the-middle. Gerontological studies on this topic reflect controversies on the concept as well as on the size of the phenomenon. Our study attempts to demonstrate empirically to what extent middle-aged women respond to the care demands of both the generation ahead as well as the generation behind them. A population-based sample among women aged forty to fifty-four in the Netherlands (N = 933) is utilized. The study indicates the prevalence of women-in-the-middle and presents analyses of their socio-demographic characteristics as well as of patterns of parent care. Further, the potential for a cross-cultural comparison between the Netherlands and other countries is discussed regarding parent care as a normative experience and the chances of middle-aged women getting "caught" between care demands from two generations.
