Can education improve clinical practice concerning delirium in older hospitalised patients? Results of a pre-test post-test study on an educational intervention for nursing staff.

BACKGROUND: Delirium is a common and serious complication of hospitalisation in older adults. It can lead to prolonged hospital stay, institutionalisation, and even death. However, it often remains unrecognised or is not managed adequately. The aim of this study was to evaluate the effects of an educational intervention for nursing staff on three aspects of clinical practice concerning delirium in older hospitalised patients: the frequency and correctness of screening for delirium using the 13-item Delirium Observation Screening score (DOS), and the frequency of geriatric consultations requested for older patients. The a priori expectations were that there would be an increase in all three of these outcomes. METHODS: We designed an educational intervention and implemented this on two inpatient hospital units. Before providing the educational session, the nursing staff was asked to fill out two questionnaires about delirium in older hospitalised patients. The educational session was then tailored to each unit based on the results of these questionnaires. Additionally, posters and flyers with information on the screening and management of delirium were provided and participants were shown where to find additional information. Relevant data (outcomes, demographics and background patient data) were collected retrospectively from digital medical files. Data was retrospectively collected for four different time points: three pre-test and one post-test. RESULTS: There was a significant increase in frequency of delirium screening (P = 0.001), and both units showed an increase in the correctness of the screening. No significant effect of the educational intervention was found for the proportion of patients who received a geriatric consultation (P = 0.083). CONCLUSION: The educational intervention was fairly successful in making positive changes in clinical practice: after the educational session an improvement in the frequency and correctness of screening for delirium was observed. A trend, though not significant, towards an increase in the proportion of geriatric consultations for older hospitalised patients was also observed.

The mediating role of disability and social support in the association between low vision and depressive symptoms in older adults.

PURPOSE: Vision loss is highly prevalent in old age and has a substantial impact on different aspects of quality of life including depressive symptoms. Our objective was to examine the mediating role of disability and social support in the association between low vision and depressive symptoms. METHODS: Differences in disability, social support, and depressive symptoms between 148 persons with low vision and a reference population (N = 4,792) all ≥57 years were compared. The association between low vision and depressive symptoms and the mediating role of disability and social support was examined by the means of regression. RESULTS: A significant effect of low vision on depressive symptoms was identified even after the adjustment for disability and social support (standardized beta 0.053, P < 0.001). The association between low vision and symptoms of depression was partially mediated by disability, while social support was identified as a suppressor variable. Low vision, disability, and social support showed unique contributions to depressive symptoms. CONCLUSIONS: Prevention of disability and the increase in social support may help to reduce symptoms of depression in older adults with low vision. By taking such information into account in their intervention work, health professionals working in this area may improve their care quality.

Effects of small-scale, home-like facilities in dementia care on residents' behavior, and use of physical restraints and psychotropic drugs: a quasi-experimental study.

BACKGROUND: Small-scale, home-like care environments are increasingly implemented in institutional nursing care as a model to promote resident-directed care, although evidence on its effects is sparse. This study focuses on the effects of small-scale living facilities on the behavior of residents with dementia and use of physical restraints and psychotropic drugs. METHODS: A quasi-experimental study was conducted comparing residents in two types of long-term institutional nursing care (i.e., small-scale living facilities and traditional psychogeriatric wards) on three time points: at baseline and follow-ups after six and 12 months. Residents were matched at baseline on cognitive and functional status to increase comparability of groups at baseline. Nurses assessed neuropsychiatric and depressive symptoms, agitation, social engagement, and use of physical restraints using questionnaires. Psychotropic drug use was derived from residents' medical records. RESULTS: In total, 259 residents were included: 124 in small-scale living facilities and 135 controls. Significantly fewer physical restraints and psychotropic drugs were used in small-scale living facilities compared with traditional wards. Residents in small-scale living facilities were significantly more socially engaged, at baseline and after six months follow-up, and displayed more physically non-aggressive behavior after 12 months than residents in traditional wards. No other differences were found. CONCLUSIONS: This study suggests positive effects of small-scale living facilities on the use of physical restraints and psychotropic drugs. However, the results for behavior were mixed. More research is needed to gain an insight on the relationship between dementia care environment and other residents' outcomes.

Psychosocial screening effects on health-related outcomes in patients receiving radiotherapy. A cluster randomised controlled trial.

OBJECTIVE: This study examined the short-term and long-term effects of using a screening instrument on psychological distress and health-related quality of life (HRQoL) among cancer patients receiving radiotherapy. In addition, we investigated the effect of early psychosocial treatment on patients' overall health-related outcomes as previous research showed that patients in the screening condition were referred to a psychosocial caregiver at an earlier stage. METHODS: A cluster randomised controlled trial with a randomisation at the levels of 14 radiotherapists, 568 patients was conducted. Patients were asked to complete questionnaires at 3 and 12 months follow-up. RESULTS: Mixed models analyses showed no significant intervention effects on patients' overall extent of psychosocial distress and HRQoL, both on the short and long terms. Post-hoc analyses revealed significant interactions of the intervention with early referral and improved HRQoL and anxiety, suggesting that earlier referral might influence short-term HRQoL and experienced anxiety in patients. CONCLUSIONS: Our results suggest that the use of a psychosocial screening instrument among patients receiving radiotherapy in itself does not sufficiently improve patients' health-related outcome. The effective delivery of psychosocial care depends upon several components such as identification of distress and successful implementation of screening procedures. One of the challenges is to get insight in the effects of early referral of cancer patients for psychosocial support because early referral might have a favourable effect on some of the patients' health-related outcomes.

Longitudinal changes in BMI in older adults are associated with meat consumption differentially, by type of meat consumed.

Hypotheses regarding the role of meat consumption in body weight modulation are contradictory. Prospective studies on an association between meat consumption and BMI change are limited. We assessed the association between meat consumption and change in BMI over time in 3902 men and women aged 55-69 y from the Netherlands Cohort Study. Dietary intake was estimated at baseline using a FFQ. BMI was ascertained through baseline self-reported height (1986) and weight (1986, 1992, and 2000). Analyses were based on sex-specific categories of daily total fresh meat, red meat, beef, pork, minced meat, chicken, processed meat, and fish consumption at baseline. Linear mixed effect modeling adjusted for confounders was used to assess longitudinal associations. Significant cross-sectional differences in BMI between quintiles of total meat intake were observed (P-trend < 0.01; both sexes). No association between total fresh meat consumption and prospective BMI change was observed in men (BMI change highest vs. lowest quintile after 14 y: -0.06 kg/m²; P = 0.75) and women (BMI change: 0.26 kg/m²; P = 0.20). Men with the highest intake of beef experienced a significantly lower increase in BMI after 6 and 14 y than those with the lowest intake (BMI change after 14 y 0.60 kg/m²). After 14 y, a significantly higher increase in BMI was associated with higher intakes of pork in women (BMI change highest vs. lowest quintile: 0.47 kg/m²) and chicken in both sexes (BMI change highest vs. lowest category in both men and women: 0.36 kg/m²). The results remained similar when stratifying on median baseline BMI, and age-stratified analyses yielded mixed results. Differential BMI change effects were observed for several subtypes of meat. However, total meat consumption, or factors directly related to total meat intake, was not strongly associated with weight change during the 14-y prospective follow-up in this elderly population.

Disentangling interventions to reduce fear of falling in community-dwelling older people: a systematic review and meta-analysis of intervention components.

PURPOSE: Fear of falling (FoF) is a common and debilitating problem for older people. Most multicomponent interventions show only moderate effects. Exploring the effective components may help in the optimization of treatments for FoF. MATERIALS AND METHODS: In a systematic review of five scientific literature databases, we identified randomized controlled trials with older community-dwelling people that included FoF as an outcome. There was no restriction on types of interventions. Two reviewers extracted information about outcomes and content of interventions. Intervention content was coded with a coding scheme of 68 intervention components. We compared all studies with a component to those without using univariate meta-regressions. RESULTS: Sixty-six studies, reporting on 85 interventions, were included in the systematic review. In the meta-regressions (n = 49), few components were associated with intervention effects at the first available follow up after the intervention, but interventions with meditation, holistic exercises (such as Tai Chi or Pilates) or body awareness were significantly more effective than interventions without these components. Interventions with self-monitoring, balance exercises, or tailoring were less effective compared to those without these components. CONCLUSIONS: The identified components may be important for the design and optimization of treatments to reduce FoF. Implications for rehabilitationFear of falling (FoF) is a common and debilitating issue among older people and multicomponent interventions usually show only small to moderate effects on FoF.This review and meta-analysis investigated 68 intervention components and their relation to intervention effects on FoF.Interventions with meditation, holistic exercises (such as Tai Chi), or body awareness are more effective than interventions without these components.Clinicians aiming to reduce FoF may recommend selected interventions to older people taking into account the current knowledge of intervention components.

Mediating effects of psychosocial factors on concerns about falling and daily activity in a multicomponent cognitive behavioral group intervention.

OBJECTIVES: Concerns about falling, or fear of falling, is highly common in old age and has adverse consequences. The development and understanding of interventions to reduce concerns about falling are therefore relevant. This study explored the mediating effects of psychosocial factors on trajectories of concerns about falling and daily activity in a multicomponent cognitive behavioral group intervention. METHOD: The study sample comprised 540 community-dwelling adults aged 70 years or older, with concerns about falling and associated activity avoidance, who participated in a randomized controlled trial evaluating this intervention. Control beliefs, self-efficacy beliefs, outcome expectations, and social interactions, as potential mediators, and concerns about falling and daily activity, as outcome variables, were assessed at baseline, and at two, eight, and 14 months. Data were analyzed with mixed-effects regression models. RESULTS: Small to moderate statistically significant effects of the intervention on the potential mediators were found at nearly all follow-up assessments. Separate psychosocial factors showed modest mediating effects on the outcomes. When all mediators were taken into account simultaneously, 44-76% of the association between the intervention and the outcomes was explained. CONCLUSION: This study showed that the multicomponent cognitive behavioral intervention improved control beliefs, self-efficacy, outcome expectations, and social interactions. These variables mediated the association between the intervention and concerns about falling or daily activity in community-dwelling older adults. This knowledge may facilitate further improvement and development of interventions to reduce concerns about falling and to increase daily activity.

Intervention Characteristics Associated With a Reduction in Fear of Falling Among Community-Dwelling Older People: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND AND OBJECTIVES: Fear of falling (FoF) is associated with decreased physical functioning and an increased fall risk. Interventions generally demonstrate moderate effects and optimized interventions are needed. Intervention characteristics, such as setting or delivery method may vary. We investigated which overarching intervention characteristics are associated with a reduction in FoF in community-dwelling older people. RESEARCH DESIGN AND METHODS: A systematic review and meta-analysis of randomized controlled trials (RCTs) in community-dwelling older people without specific diseases was performed. Associations between intervention characteristics and standardized mean differences (SMD) were determined by univariate meta-regression. Sensitivity analyses were performed. RESULTS: Data on 62 RCTs were extracted, 50 intervention groups were included in the meta-analysis. Most intervention characteristics and intervention types were not associated with the intervention effect. Supervision by a tai chi instructor (SMD: -1.047, 95% confidence interval [CI]: -1.598; -0.496) and delivery in a community setting (SMD: -0.528, 95% CI: -0.894; -0.161) were-compared to interventions without these characteristics-associated with a greater reduction in FoF. Holistic exercise, such as Pilates or yoga (SMD: -0.823, 95% CI: -1.255; -0.392), was also associated with a greater reduction in FoF. Delivery at home (SMD: 0.384, 95% CI: 0.002; 0.766) or with written materials (SMD: 0.452, 95% CI: 0.088; 0.815) and tailoring were less effective in reducing FoF (SMD: 0.687, 95% CI: 0.364; 1.011). DISCUSSION AND IMPLICATIONS: Holistic exercise, delivery with written materials, the setting and tailoring potentially represent characteristics to take into account when designing and improving interventions for FoF in community-dwelling older people.

Small-scale, homelike facilities versus regular psychogeriatric nursing home wards: a cross-sectional study into residents' characteristics.

BACKGROUND: Nursing home care for people with dementia is increasingly organized in small-scale and homelike care settings, in which normal daily life is emphasized. Despite this increase, relatively little is known about residents' characteristics and whether these differ from residents in traditional nursing homes. This study explored and compared characteristics of residents with dementia living in small-scale, homelike facilities and regular psychogeriatric wards in nursing homes, focusing on functional status and cognition. METHODS: A cross-sectional study was conducted, including 769 residents with dementia requiring an intensive level of nursing home care: 586 from regular psychogeriatric wards and 183 residents from small-scale living facilities. Functional status and cognition were assessed using two subscales from the Resident Assessment Instrument Minimum Data Set (RAI-MDS): the Activities of Daily Living-Hierarchy scale (ADL-H) and the Cognitive Performance Scale (CPS). In addition, care dependency was measured using Dutch Care Severity Packages (DCSP). Finally, gender, age, living condition prior to admission and length of stay were recorded. Descriptive analyses, including independent samples t- tests and chi-square tests, were used. To analyze data in more detail, multivariate logistic regression analyses were performed. RESULTS: Residents living in small-scale, homelike facilities had a significantly higher functional status and cognitive performance compared with residents in regular psychogeriatric wards. In addition, they had a shorter length of stay, were less frequently admitted from home and were more often female than residents in regular wards. No differences were found in age and care dependency. While controlling for demographic variables, the association between dementia care setting and functional status and cognition remained. CONCLUSIONS: Although residents require a similar intensive level of nursing home care, their characteristics differ among small-scale living facilities and regular psychogeriatric wards. These differences may limit research into effects and feasibility of various types of dementia care settings. Therefore, these studies should take resident characteristics into account in their design, for example by using a matching procedure.

Nurse-led self-management group programme for patients with congestive heart failure: randomized controlled trial.

AIM: This paper reports on of the effects of the Chronic Disease Self-Management Programme on psychosocial attributes, self-care behaviour and quality of life among congestive heart failure patients who experienced slight to marked limitation of physical activity. BACKGROUND: Most self-management programmes for congestive heart failure patients emphasize the medical aspects of this chronic condition, without incorporating psychosocial aspects of self-management. The programme has been used with various patient groups, but its effectiveness with congestive heart failure patients when led by pairs of cardiac nurse specialists and peer leaders is unknown. METHOD: A randomized controlled trial with 12 months of follow-up from start of the programme was conducted with 317 patients. Control group patients (n = 131) received usual care, consisting of regular outpatient checkups. Intervention group patients (n = 186) received usual care and participated in the six-week self-management programme. The programme teaches patients medical, social and emotional self-management skills. Twenty-one classes were conducted in six hospitals in the Netherlands, and data were collected between August 2004 and January 2007. RESULTS: Directly after the programme, statistically significant effects were found for cognitive symptom management (P < 0.001), self-care behaviour (P = 0.008) and cardiac-specific quality of life (P = 0.005). No effects were found at 6- and 12-month follow-up. CONCLUSION: Further research is necessary to study how long-term effectiveness of the programme with patients with congestive heart failure can be achieved, and how successful adaptations of the programme can be integrated into standard care.

Alcohol consumption and risk of pancreatic cancer in the Netherlands cohort study.

To examine prospectively the relation between alcohol consumption and pancreatic cancer risk, the authors analyzed data from the Netherlands Cohort Study. Participants were 120,852 persons who completed a baseline questionnaire in 1986. After 13.3 years of follow-up, 350 cases of pancreatic cancer (67% microscopically confirmed) were available for analysis. Compared with abstention, the highest category of alcohol consumption (> or =30 g/day of ethanol) was positively associated with pancreatic cancer risk (for all cases, rate ratio = 1.57, 95% confidence interval: 1.03, 2.39; P(trend) = 0.12; for microscopically confirmed cases, rate ratio = 1.54, 95% confidence interval: 0.94, 2.54; P(trend) = 0.22). In a subgroup of stable alcohol users (no change during the 5 years before baseline), a similarly increased risk of pancreatic cancer was found. This increased risk was limited to the first 7 years of follow-up. No associations were observed between consumption of specific alcoholic beverages and risk of pancreatic cancer. The associations were not modified by folate intake or smoking. Overall, these findings suggest an increased pancreatic cancer risk for persons with a high ethanol intake (> or =30 g/day). However, this increased risk was observed only during the first 7 years of follow-up.

The impact of a self-management group programme on health behaviour and healthcare utilization among congestive heart failure patients.

AIMS: The 'Chronic Disease Self-Management Programme' (CDSMP) emphasizes patients' responsibility for the day-to-day management of their condition(s) and has shown favourable effects on health behaviour and healthcare utilization among various groups of patients with chronic conditions. However, the effects of the CDSMP among congestive heart failure (CHF) patients are unknown. We therefore aimed to assess the effects of the CDSMP on health behaviour and healthcare utilization in patients with CHF. METHODS AND RESULTS: This randomized, controlled trial with 12 months of follow-up included 317 CHF patients with a slight to marked limitation of physical activity. Control patients (n = 131) received usual care, consisting of regular checkups at an outpatient clinic. Intervention group patients (n = 186) received usual care and participated in a 6-week self-management group programme. Favourable effects on walking for exercise and other physical activities such as aerobic, stretching, and strength exercises, sports, and gardening were reported in the intervention group immediately after completion of the programme. The effect of the programme on other physical activities extended to 6 months of follow-up. No favourable effects were found for the other outcomes. CONCLUSION: The CDSMP significantly improved physical activity among CHF patients for up to 6 months after the end of the programme; however, it did not affect other health behaviour outcomes or healthcare utilization.

The effectiveness of the Screening Inventory of Psychosocial Problems (SIPP) in cancer patients treated with radiotherapy: design of a cluster randomised controlled trial.

BACKGROUND: The Screening Inventory of Psychosocial Problems (SIPP) is a short, validated self-reported questionnaire to identify psychosocial problems in Dutch cancer patients. The one-page 24-item questionnaire assesses physical complaints, psychological complaints and social and sexual problems. Very little is known about the effects of using the SIPP in consultation settings. Our study aims are to test the hypotheses that using the SIPP (a) may contribute to adequate referral to relevant psychosocial caregivers, (b) should facilitate communication between radiotherapists and cancer patients about psychosocial distress and (c) may prevent underdiagnosis of early symptoms reflecting psychosocial problems. This paper presents the design of a cluster randomised controlled trial (CRCT) evaluating the effectiveness of using the SIPP in cancer patients treated with radiotherapy. METHODS/DESIGN: A CRCT is developed using a Solomon four-group design (two intervention and two control groups) to evaluate the effects of using the SIPP. Radiotherapists, instead of cancer patients, are randomly allocated to the experimental or control groups. Within these groups, all included cancer patients are randomised into two subgroups: with and without pre-measurement. Self-reported assessments are conducted at four times: a pre-test at baseline before the first consultation and a post-test directly following the first consultation, and three and 12 months after baseline measurement. The primary outcome measures are the number and types of referrals of cancer patients with psychosocial problems to relevant (psychosocial) caregivers. The secondary outcome measures are patients' satisfaction with the radiotherapist-patient communication, psychosocial distress and quality of life. Furthermore, a process evaluation will be carried out. Data of the effect-evaluation will be analysed according to the intention-to-treat principle and data regarding the types of referrals to health care providers and patient satisfaction about the with radiotherapists will be analysed by means of descriptive techniques. The process evaluation data will also be analysed by means of descriptive techniques. DISCUSSION: Using the SIPP may prevent underdiagnosis of early symptoms reflecting psychosocial problems, should facilitate communication between physicians and patients about psychosocial distress and may contribute to adequate referral to relevant (psychosocial) caregivers.

Effect of adenosine 5'-triphosphate infusions on the nutritional status and survival of preterminal cancer patients.

The aim of the study was to investigate the effect of intravenous infusions of adenosine 5'-triphosphate (ATP) on nutritional status and survival in preterminal cancer patients. Ninety-nine preterminal cancer patients (estimated life expectancy 1-6 months) with mixed tumor types were randomly allocated to receive either intravenous ATP weekly (8-10 h/week, maximum 50 microg/kg/min) for 8 weeks, or no ATP (control group). Nutritional status parameters were assessed until 8 weeks, and analyzed by repeated-measures analysis of covariance. Cox proportional hazards models were fitted to assess the effect of ATP on short-term (0-8 weeks) and long-term (0-6 months) survival. Fifty-one patients were randomized to ATP and 48 to the control group. Results showed a significant favorable effect of ATP on triceps skin fold thickness [between-group difference per 8 weeks 1.76 mm, 95% confidence interval (CI): 0.48-3.12 mm; P = 0.009] and on short-term survival [0-8 weeks hazard ratio (HR): 0.40, 95% CI: 0.17-0.95; P = 0.037]. In weight-stable patients and in lung cancer patients, long-term survival (0-6 months) was also significantly better in ATP-treated patients (weight-stable patients HR: 0.40, 95% CI: 0.19-0.83; P = 0.014; patients with lung cancer: HR: 0.35, 95% CI: 0.14-0.88; P = 0.025). In conclusion, in this population of preterminal cancer patients, ATP infusions, at the dose and schedule studied, had a favorable effect on triceps skin fold thickness and survival, especially in weight-stable patients and patients with lung cancer. Larger studies are warranted to confirm these findings and to further define the effect of ATP on tumor growth and survival.

The effects of small-scale, homelike facilities for older people with dementia on residents, family caregivers and staff: design of a longitudinal, quasi-experimental study.

BACKGROUND: Small-scale and homelike facilities for older people with dementia are rising in current dementia care. In these facilities, a small number of residents live together and form a household with staff. Normal, daily life and social participation are emphasized. It is expected that these facilities improve residents' quality of life. Moreover, it may have a positive influence on staff's job satisfaction and families involvement and satisfaction with care. However, effects of these small-scale and homelike facilities have hardly been investigated. Since the number of people with dementia increases, and institutional long-term care is more and more organized in small-scale and homelike facilities, more research into effects is necessary. This paper presents the design of a study investigating effects of small-scale living facilities in the Netherlands on residents, family caregivers and nursing staff. METHODS AND DESIGN: A longitudinal, quasi-experimental study is carried out, in which 2 dementia care settings are compared: small-scale living facilities and regular psychogeriatric wards in traditional nursing homes. Data is collected from residents, their family caregivers and nursing staff at baseline and after 6 and 12 months of follow-up. Approximately 2 weeks prior to baseline measurement, residents are screened on cognition and activities of daily living (ADL). Based on this screening profile, residents in psychogeriatric wards are matched to residents living in small-scale living facilities. The primary outcome measure for residents is quality of life. In addition, neuropsychiatric symptoms, depressive symptoms and social engagement are assessed. Involvement with care, perceived burden and satisfaction with care provision are primary outcome variables for family caregivers. The primary outcomes for nursing staff are job satisfaction and motivation. Furthermore, job characteristics social support, autonomy and workload are measured. A process evaluation is performed to investigate to what extent small-scale living facilities and psychogeriatric wards are designed as they were intended. In addition, participants' satisfaction and experiences with small-scale living facilities are investigated. DISCUSSION: A longitudinal, quasi-experimental study is presented to investigate effects of small-scale living facilities. Although some challenges concerning this design exist, it is currently the most feasible method to assess effects of this relatively new dementia care setting.

Influenza vaccination in the elderly: 25 years follow-up of a randomized controlled trial. No impact on long-term mortality.

Influenza vaccination is proven effective in preventing influenza. However, long-term effects on mortality have never been supported by direct evidence. In this study we assessed the long-term outcome of influenza vaccination on mortality in the elderly by conducting a 25-year follow-up study of a RCT on the efficacy of influenza vaccination as baseline. The RCT had been conducted in the Netherlands 5 years before vaccination was recommended for those aged >65 and 17 years before recommending it for those aged >60. The RCT included 1838 community-dwelling elderly aged ≥ 60 that had received an intramuscular injection with the inactivated quadrivalent influenza vaccine (n = 927) or placebo (n = 911) during the 1991/1992 winter. In our follow-up study, outcomes included all-cause mortality, influenza-related mortality and seasonal mortality. Unadjusted and adjusted hazard ratios (HRs) were estimated by Cox regression and sub-hazard ratios (SHRs) by competing risk models. Secondary analyses included subgroup analyses by age and disease status. The vital status up to January 1, 2017 was provided in 1800/1838 (98%) of the cases. Single influenza vaccination did not reduce all-cause mortality when compared to placebo (adjusted HR 0.95, 95% CI 0.85-1.05). Also, no differences between vaccination and placebo group were shown for underlying causes of death or seasonal mortality. In those aged 60-64, median survival increased with 20.1 months (95% CI 2.4-37.9), although no effects on all-cause mortality (adjusted HR 0.86, 95% CI 0.72-1.03) could be demonstrated in survival analysis. In conclusion, this study did not demonstrate a statistically significant effect following single influenza vaccination on long-term mortality in community-dwelling elderly in general. We propose researchers designing future studies on influenza vaccination in the elderly to fit these studies for longer-term follow-up, and suggest age-group comparisons in observational research.

Cost-effectiveness of an integrated 'fast track' rehabilitation service for multi-trauma patients: A non-randomized clinical trial in the Netherlands.

BACKGROUND: Multidisciplinary rehabilitation has been recommended for multi-trauma patients, but there is only low-quality evidence to support its use with these patients. This study examined whether a Supported Fast track multi-Trauma Rehabilitation Service (Fast Track) was cost-effective compared to conventional trauma rehabilitation service (Care As Usual) in patients with multi-trauma from a societal perspective with a one-year follow-up. METHODS: An economic evaluation alongside a prospective, multi-center, non-randomized, controlled clinical study, was conducted in the Netherlands. The primary outcome measure was the Functional Independence Measure (FIM). Generic Quality of Life and Quality Adjusted Life Years (QALYs) of the patients were derived using the Short-form 36 Health Status Questionnaire. Incremental Cost-Effectiveness Ratios (ICERs) were stated in terms of costs per unit of FIM improvement and costs per QALY. To investigate the uncertainty around the ICERs, non-parametric bootstrapping was used. RESULTS: In total, 132 patients participated, 65 Fast Track patients and 67 Care As Usual patients. Mean total costs per person were €18,918 higher in the Fast Track group than in the Care As Usual group. Average incremental effects on the FIM were 3.7 points (in favor of the Fast Track group) and the incremental (extra) bootstrapped costs were €19,033, resulting in an ICER for cost per FIM improvement of €5,177. Care As Usual dominated Fast Track in cost per QALY as it gave both higher QALYs and lower costs. All sensitivity analyses attested to the robustness of our results. CONCLUSIONS: This study demonstrated that a multidisciplinary rehabilitation program for multi-trauma patients according to the supported fast track principle is promising but cost-effectiveness evidence remains inconclusive. In terms of functional outcome, Fast Track was more expensive but yielded also more effects compared to the Care As Usual group. Looking at the costs per QALYs, unfavorable ICERs were found. Given the lack of a willingness-to-pay threshold for functional recovery and the relatively short time horizon, it is not possible to draw firm conclusions about the first.

Effects on health care use and associated cost of a home visiting program for older people with poor health status: a randomized clinical trial in the Netherlands.

BACKGROUND: Home visiting programs have been developed to improve the functional abilities of older people and subsequently to reduce the use of institutional care services. The results of trials have been inconsistent and their cost-effectiveness uncertain. Home visits for a high-risk population rather than the general population seems a promising approach. We therefore studied the effects of a home visiting program for older people with poor health. This article describes the effects on health care use and associated cost. METHODS: We conducted a randomized clinical trial among 330 community-dwelling citizens, aged 70-84 years, in the Netherlands. Participants in the intervention group (n = 160) received eight home visits by a trained home nurse over an 18-month period; a multidimensional geriatric assessment of problems was included. The main outcomes are: admissions to hospital, nursing home, and home for older persons; contacts with medical specialists, general practitioners, and paramedics; and hours of home care help. The data on health care use were mostly obtained from computerized databases of various medical administration offices; the follow-up period was 24 months. RESULTS: Inpatient and outpatient health care use was similar for both groups, with the exception of a higher distribution of aids and in-home modifications in favor of the intervention group. No differences were found between the intervention and control group in health care cost. CONCLUSION: The home visiting program did not appear to have any effect on the health care use of older people with poor health and had a low chance of being cost-effective. We conclude that these visits are probably not beneficial for such persons within the health care setting in the Netherlands or comparable settings in other Western countries.

Working in small-scale, homelike dementia care: effects on staff burnout symptoms and job characteristics. A quasi-experimental, longitudinal study.

AIM: This paper reports on a quasi-experimental, longitudinal study on the effects of working in a new type of dementia care facility (i.e. small-scale living facilities) on staff burnout symptoms and job characteristics (job autonomy, social support, physical demands and workload). METHODS: It is hypothesised that nursing staff working in small-scale facilities experience fewer burnout symptoms, more autonomy and social support, and fewer symptoms of physical demands and workload compared with staff in regular wards. Two types of long-term institutional nursing care settings were included: 28 houses in small-scale living facilities and 21 regular psychogeriatric wards in nursing homes. At baseline and at follow-ups after 6 and 12 months nursing staff were assessed by means of self-report questionnaires. In total, 305 nursing staff members were included in the study, 114 working in small-scale living facilities (intervention group) and 191 in regular wards (control group). RESULTS: No overall effects on burnout symptoms were detected. Significantly fewer physical demands and lower workload were experienced by staff working in small-scale living facilities compared with staff in regular wards. They also experienced more job autonomy. No significant effect was found for overall social support in the total group. CONCLUSIONS: This study suggests positive effects of the work environment on several work characteristics. Organisational climate differs in the two conditions, which might account for our results. This may influence nursing staff well-being and has important implications for nursing home managers and policy makers. Future studies should enhance our understanding of the influence of job characteristics on outcomes.

Effects of a Medication Review on Delirium in Older Hospitalised Patients: A Comparative Retrospective Cohort Study.

BACKGROUND: Delirium in older hospitalised patients is a common and serious disorder. Polypharmacy and certain medications are risk factors for developing delirium. A medication review could benefit older hospitalised patients with delirium. OBJECTIVES: (1) Evaluate the effects of medication review on length of delirium, length of hospital stay, mortality, and discharge destination; and (2) describe and analyse the proposed changes to medication and its implementation by the treating physician. SETTING: The study was conducted at Maastricht University Medical Centre+. METHODS: We compared two cohorts of older patients with delirium: the first cohort from before introducing the medication review, and a second cohort 5 months after introduction of the medication review. Data were extracted from the patients' digital medical records. RESULTS: A significant interaction effect of cohort and number of medications taken by the patient was found for duration of delirium: patients from the second cohort taking between zero and six medications had significantly shorter delirious episodes than patients in the first cohort. This effect bordered on significance for patients taking between seven and 11 medications, but disappeared for patients taking 12 or more medications. No other statistically significant differences were found between the cohorts. The proposed changes in medication were implemented for 71% of the patients. CONCLUSION: A medication review seems to significantly decrease the length of an older patient's delirious episode. Given the clinical relevance of these findings, we advise medication reviews for all older patients who are delirious or are at risk of developing delirium.
