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.

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.
