The evolution of the subjective well-being of the general population during the COVID-19 pandemic period: the case of Belgium.

The consequences of the COVID-19 pandemic period on a nation's well-being remain inadequately understood, especially over time. Therefore, this research aims to map the changes in the subjective well-being (SWB) of the general Belgian adult population during the COVID-19 pandemic. Analyses of variances (ANOVA) were performed to evaluate the changes in SWB during the pandemic at five different time points during the period from February 2020 until December 2022 using repeated cross-sectional representative samples of the Belgian population. The differences over time in subjective well-being were investigated in terms of life evaluation, positive affect, and negative affect. The changes in autonomy, competence, relatedness, loneliness and peace of mind were also explored as explanatory variables. Moderation analyses were performed to investigate the differential changes in well-being for different age groups. Our results show the subjective well-being of the Belgian population decreased during the COVID-19 pandemic, notably during the second lockdown and the fifth wave. Furthermore, younger individuals are significantly more susceptible to negative changes in well-being during the pandemic period. Finally, our results show that peace of mind is an important predictor of all SWB components during the pandemic. Based on these results several policy recommendations are formulated.

Evaluating the health and health economic impact of the COVID-19 pandemic on delayed cancer care in Belgium: A Markov model study protocol.

INTRODUCTION: Cancer causes a substantial burden to our society, both from a health and an economic perspective. To improve cancer patient outcomes and lower society expenses, early diagnosis and timely treatment are essential. The recent COVID-19 crisis has disrupted the care trajectory of cancer patients, which may affect their prognosis in a potentially negative way. The purpose of this paper is to present a flexible decision-analytic Markov model methodology allowing the evaluation of the impact of delayed cancer care caused by the COVID-19 pandemic in Belgium which can be used by researchers to respond to diverse research questions in a variety of disruptive events, contexts and settings. METHODS: A decision-analytic Markov model was developed for 4 selected cancer types (i.e. breast, colorectal, lung, and head and neck), comparing the estimated costs and quality-adjusted life year losses between the pre-COVID-19 situation and the COVID-19 pandemic in Belgium. Input parameters were derived from published studies (transition probabilities, utilities and indirect costs) and administrative databases (epidemiological data and direct medical costs). One-way and probabilistic sensitivity analyses are proposed to consider uncertainty in the input parameters and to assess the robustness of the model's results. Scenario analyses are suggested to evaluate methodological and structural assumptions. DISCUSSION: The results that such decision-analytic Markov model can provide are of interest to decision makers because they help them to effectively allocate resources to improve the health outcomes of cancer patients and to reduce the costs of care for both patients and healthcare systems. Our study provides insights into methodological aspects of conducting a health economic evaluation of cancer care and COVID-19 including insights on cancer type selection, the elaboration of a Markov model, data inputs and analysis.

How job demands and job resources contribute to our overall subjective well-being.

Objectives: How the work environment contributes to employees' overall subjective well-being remains inadequately explored. Building upon the seminal Job Demands-Resources model, this study aims to test a complex model that combines leadership, job demands, and job resources, as factors contributing either indirectly (via job satisfaction) or directly to employees' subjective well-being (SWB). Methods: The cross-sectional data (N = 1,859) of the Belgian National happiness study (2020) were used. Leadership (satisfaction with leadership; perceived supervisor support), job demands (role conflict; job insecurity; work-private conflict; perceived working conditions), job resources (autonomy; relatedness; competence; skill utilization; personal growth), job satisfaction and subjective well-being (life evaluation; positive affect; negative affect) were assessed via self-report questionnaires. The proposed model investigates the direct impact of job demands and resources on SWB, as well as the indirect impact with job satisfaction as mediating factor, and was tested using the Structural Equation Modeling technique. Results: Findings supported the proposed model. Both job demands and job resources have a direct relationship with SWB. Job resources are positively related to overall SWB, whereas job demands negatively affected SWB. Moreover, job resources are more strongly related to SWB compared to job demands. The demands and resources also indirectly contribute to employee's SWB via job satisfaction as job satisfaction appeared to mediate these relationships. Conclusion: The current study shows that both job demands and resources directly and indirectly contribute to employees' SWB. Creating a supportive and healthy work environment is thus of paramount importance in order to foster employees' SWB. In particular, investing in improving job resources may be a fruitful approach to promote employees' overall subjective well-being.

Social inequalities and long-term health impact of COVID-19 in Belgium: protocol of the HELICON population data linkage.

INTRODUCTION: Data linkage systems have proven to be a powerful tool in support of combating and managing the COVID-19 pandemic. However, the interoperability and the reuse of different data sources may pose a number of technical, administrative and data security challenges. METHODS AND ANALYSIS: This protocol aims to provide a case study for linking highly sensitive individual-level information. We describe the data linkages between health surveillance records and administrative data sources necessary to investigate social health inequalities and the long-term health impact of COVID-19 in Belgium. Data at the national institute for public health, Statistics Belgium and InterMutualistic Agency are used to develop a representative case-cohort study of 1.2 million randomly selected Belgians and 4.5 million Belgians with a confirmed COVID-19 diagnosis (PCR or antigen test), of which 108 211 are COVID-19 hospitalised patients (PCR or antigen test). Yearly updates are scheduled over a period of 4 years. The data set covers inpandemic and postpandemic health information between July 2020 and January 2026, as well as sociodemographic characteristics, socioeconomic indicators, healthcare use and related costs. Two main research questions will be addressed. First, can we identify socioeconomic and sociodemographic risk factors in COVID-19 testing, infection, hospitalisations and mortality? Second, what is the medium-term and long-term health impact of COVID-19 infections and hospitalisations? More specific objectives are (2a) To compare healthcare expenditure during and after a COVID-19 infection or hospitalisation; (2b) To investigate long-term health complications or premature mortality after a COVID-19 infection or hospitalisation; and (2c) To validate the administrative COVID-19 reimbursement nomenclature. The analysis plan includes the calculation of absolute and relative risks using survival analysis methods. ETHICS AND DISSEMINATION: This study involves human participants and was approved by Ghent University hospital ethics committee: reference B.U.N. 1432020000371 and the Belgian Information Security Committee: reference Beraadslaging nr. 22/014 van 11 January 2022, available via https://www.ehealth.fgov.be/ehealthplatform/file/view/AX54CWc4Fbc33iE1rY5a?filename=22-014-n034-HELICON-project.pdf. Dissemination activities include peer-reviewed publications, a webinar series and a project website.The pseudonymised data are derived from administrative and health sources. Acquiring informed consent would require extra information on the subjects. The research team is prohibited from gaining additional knowledge on the study subjects by the Belgian Information Security Committee's interpretation of the Belgian privacy framework.

Do Cash-For-Care Schemes Increase Care Users' Experience of Empowerment? A Systematic Review.

BACKGROUND: In cash-for-care schemes, care users are granted a budget or given a voucher to purchase care services, under the assumption that this will enable them to become engaged and empowered customers, leading to more person-centered care. However, opponents of such schemes argue that the responsibility of organizing care is thereby shifted from governments to care users, thus reducing care users' experience of empowerment. The tension between these opposing discourses supposes that other factors affect care users' experience of empowerment. OBJECTIVE: This systematic review explores the experiences of empowerment and person-centered care of budget holders in cash-for-care schemes and the antecedents that can affect this experience. METHOD: We screened seven databases up to October 10, 2022. To be included, articles needed to be peer-reviewed, written in English or French, and contain empirical evidence of the experience of empowerment of budget holders in the form of qualitative or quantitative data. RESULTS: The initial search identified 10,966 records of which 90 articles were retained for inclusion. The results show that several contextual and personal characteristics determine whether cash-for-care schemes increase empowerment. The identified contextual factors are establishing a culture of change, supportive financial climate, flexible regulatory framework, and access to support and information. The identified personal characteristics refer to the financial, social, and personal resources of the care user. CONCLUSION: This review confirms that multiple factors can affect care users' experience of empowerment. However, active cooperation and communication between care user and care provider are essential if policy makers wish to increase care users' experience of empowerment.

Optimizing non-pharmaceutical intervention strategies against COVID-19 using artificial intelligence.

One key task in the early fight against the COVID-19 pandemic was to plan non-pharmaceutical interventions to reduce the spread of the infection while limiting the burden on the society and economy. With more data on the pandemic being generated, it became possible to model both the infection trends and intervention costs, transforming the creation of an intervention plan into a computational optimization problem. This paper proposes a framework developed to help policy-makers plan the best combination of non-pharmaceutical interventions and to change them over time. We developed a hybrid machine-learning epidemiological model to forecast the infection trends, aggregated the socio-economic costs from the literature and expert knowledge, and used a multi-objective optimization algorithm to find and evaluate various intervention plans. The framework is modular and easily adjustable to a real-world situation, it is trained and tested on data collected from almost all countries in the world, and its proposed intervention plans generally outperform those used in real life in terms of both the number of infections and intervention costs.

Psychosocial factors associated with health-related quality of life in patients with chronic disease: Results of a cross-sectional survey.

OBJECTIVE: The impact of various psychosocial factors (sense of coherence, illness perception, patient enablement, self-efficacy, health literacy, personality) is not fully understood across a wide range of chronic diseases, and in particular in patients with multimorbidity. As such, this study assessed the key psychosocial factors associated with impaired health-related quality of life (HRQoL) in patients with one or more chronic diseases based on cross-sectional data collected in Flanders (Belgium). METHODS: Cross-sectional data on 544 chronically ill patients were analysed. Multiple linear regression models were built to analyze the key psychosocial factors associated with HRQoL (EQ-5D-5Lindex as dependent factor). RESULTS: Overall, the strongest independently associated factor with HRQoL was illness perceptions (ß = -0.52, P < 0.001). In addition, sense of coherence (ß = 0.14, P = < 0.05) was independently positively associated with HRQoL. Moreover, after stratification for multimorbidity, the negative association of illness perceptions with HRQoL was stronger when multimorbidity is present compared to when it is absent (ß = -0.62, P < 0.001 vs ß = -0.38, P < 0.001). CONCLUSIONS: This study revealed interesting associations of the modifiable psychosocial factors of illness perceptions and sense of coherence with HRQoL in a population of chronically ill persons. Given that the burden of chronic diseases will rise in the next decades, designing and implementing interventions that enhance these psychosocial abilities of patients, especially illness perceptions in multimorbid patients, is needed in order to reduce the burden of chronic diseases in terms of impaired HRQoL.

Polypharmacy and Health-Related Quality of Life/Psychological Distress Among Patients With Chronic Disease.

INTRODUCTION: To date, no study has investigated the impact of polypharmacy (use of ≥5 medications concurrently) on health-related quality of life (HRQOL) and psychological distress in a combined sample of chronic disease patients and patients with multimorbidity, using diverse HRQOL measures. This study aimed to explore the association between polypharmacy and HRQOL/psychological distress by using data from a cross-sectional study in Flanders (Belgium). METHODS: We analyzed cross-sectional survey data on 544 chronically ill patients recruited from June 2019 through June 2021. HRQOL was measured with the EuroQol-5 Dimension-5 Level questionnaire (EQ-5D-5L) and the 12-Item Short Form Health Survey (SF-12); psychological distress was measured with the Hospital Anxiety and Depression Scale (HADS). Multiple linear regression models were built to assess the association between polypharmacy and HRQOL/psychological distress. RESULTS: Overall, compared with patients without polypharmacy, patients with polypharmacy reported worse EQ-5D-5L index values, EuroQol visual analogue scale (EQ-VAS) scores, SF-12 physical component scores (PCS), SF-12 mental component scores (MCS), and HADS anxiety and depression subscales. In the final regression model adjusting for age, sex, educational attainment, and multimorbidity, polypharmacy remained significantly associated with lower HRQOL in terms of the EQ-5D-5L index (ß = -0.12; P = .008), EQ-VAS (ß = -0.11; P = .01), and SF-12 PCS (ß = -0.15; P = .002) but not with psychological distress (HADS) and SF-12 MCS. CONCLUSION: This study found that polypharmacy was negatively associated with the physical domain of HRQOL, but not with the mental domain, among patients with chronic diseases. These results may be especially important for patients with multimorbidity, given their greater risk of polypharmacy.

The impact of multimorbidity patterns on health-related quality of life in the general population: results of the Belgian Health Interview Survey.

BACKGROUND: Chronic diseases and multimorbidity are a major cause of disease burden-for patients, caregivers, and society. Little is known however about potential interaction effects between specific disease combinations. Besides an additive effect, the presence of multiple conditions could also act synergistically or antagonistically regarding the impact on patients' health-related quality of life (HRQoL). The aim was to estimate the impact of coexisting chronic diseases on HRQoL of the adult general Belgian population. METHODS: The Belgian Health Interview Survey 2018 provided data on self-reported chronic conditions and HRQoL (EQ-5D-5L) for a nationally representative sample. Linear mixed models were used to analyze two-way and three-way interactions of disease combinations on HRQoL. RESULTS: Multimorbidity had a prevalence of 46.7% (≥ 2 conditions) and 29.7% (≥ 3 conditions). HRQoL decreased considerably with the presence of multiple chronic diseases. 14 out of 41 dyad combinations and 5 out of 13 triad combinations showed significant interactions, with a dominant presence of negative/synergistic effects. Positive/antagonistic effects were found in more subjective chronic diseases such as depression and chronic fatigue. Conditions appearing the most frequently in significant disease pair interactions were dorsopathies, respiratory diseases, and arthropathies. CONCLUSIONS: Diverse multimorbidity patterns, both dyads and triads, were synergistically or antagonistically associated with lower HRQoL. Tackling the burden of multimorbidity is needed, especially because most disease combinations affect each other synergistically, resulting in a greater reduction in HRQoL. Further knowledge about those multimorbidity patterns with a greater impact on HRQoL is needed to better understand disease burden beyond mortality and morbidity data.

Cost-Effectiveness of COVID-19 Policy Measures: A Systematic Review.

OBJECTIVES: The COVID-19 pandemic has had a major impact on our society, with drastic policy restrictions being implemented to contain the spread of the severe acute respiratory syndrome coronavirus 2. This study aimed to provide an overview of the available evidence on the cost-effectiveness of various coronavirus disease 2019 policy measures. METHODS: A systematic literature search was conducted in PubMed, Embase, and Web of Science. Health economic evaluations considering both costs and outcomes were included. Their quality was comprehensively assessed using the Consensus Health Economic Criteria checklist. Next, the quality of the epidemiological models was evaluated. RESULTS: A total of 3688 articles were identified (March 2021), of which 23 were included. The studies were heterogeneous with regard to methodological quality, contextual factors, strategies' content, adopted perspective, applied models, and outcomes used. Overall, testing/screening, social distancing, personal protective equipment, quarantine/isolation, and hygienic measures were found to be cost-effective. Furthermore, the most optimal choice and combination of strategies depended on the reproduction number and context. With a rising reproduction number, extending the testing strategy and early implementation of combined multiple restriction measures are most efficient. CONCLUSIONS: The quality assessment highlighted numerous flaws and limitations in the study approaches; hence, their results should be interpreted with caution because the specific context (country, target group, etc) is a key driver for cost-effectiveness. Finally, including a societal perspective in future evaluations is key because this pandemic has an indirect impact on the onset and treatment of other conditions and on our global economy.

Boosting Perceived Customer Orientation as a Driver of Patient Satisfaction.

OBJECTIVE: Several hospitals have embraced customer orientation as a strategy to better meet patients' needs, desires, and wishes. This study therefore investigates how hospitals can boost the extent to which patients feel treated in a customer-oriented way by staff (hereafter, "perceived customer orientation") and its implications for their satisfaction with the hospital. DESIGN: A cross-sectional study of hospital staff's interpersonal skills (interpersonal quality) and the atmosphere and physical features of the hospital (environmental quality) as drivers of perceived customer orientation and its satisfaction implications. PARTICIPANTS AND SETTING: Two hundred eighty-nine patients in seven surgery wards and two day-surgery departments of a Belgian hospital. MAIN OUTCOME MEASURES: Perceived customer orientation and patient satisfaction. RESULTS: Our results show that interpersonal and environmental qualities have a positive impact on perceived customer orientation, with the interpersonal skills of nursing staff having a greater effect than those of physicians. Perceived customer orientation, however, matters most for patient satisfaction when the nature of the service involves high-contact frequency. CONCLUSIONS: Interpersonal and environmental qualities may help to ensure that patients feel treated in a customer-oriented way, which improves patient satisfaction with the hospital.

The relationship of nursing home price and quality of life.

BACKGROUND: Knowledge about the relationship between the residents' Quality of Life (QOL) and the nursing home price is currently lacking. Therefore, this study investigates the relationship between 11 dimensions of QOL and nursing homes price in Flemish nursing homes. METHODS: The data used in this cross-sectional study were collected by the Flemish government from years 2014 to 2017 and originates from 659 Flemish nursing homes. From 2014 to 2016, data on the QOL of 21,756 residents was assessed with the InterRAI instrument. This instrument contains 11 QOL dimensions. Multiple linear regression analyses were conducted to examine the research question. RESULTS: The multiple linear regressions indicated that a 10 euro increase in the daily nursing home price is associated with a significant decrease (P <  0.001) of 0.1 in 5 dimensions of QOL (access to services, comfort and environment, food and meals, respect, and safety and security). Hence, our results indicate that the association between price and QOL is very small. When conducting a subgroup analysis based on ownership type, the earlier found results remained only statistically significant for private nursing homes. CONCLUSION: Our findings show that nursing home price is of limited importance with respect to resident QOL. Contrary to popular belief, our study demonstrates a limited negative effect of price on QOL. Further research that includes other indicators of QOL is needed to allow policymakers and nursing home managers to improve nursing home residents' QOL.

Cost-effectiveness of an in-home respite care program to support informal caregivers of persons with dementia: A model-based analysis.

OBJECTIVES: To evaluate cost-effectiveness of an in-home respite care program in addition to standard community-based dementia care to support informal caregivers of persons with dementia compared with standard community-based dementia care. METHODS: An age-dependent decision-analytic Markov model was applied from a third-party payer and a societal perspective projecting results of a quasi-experimental study over a time horizon of 5 years assuming a repetition of the program every 6 months. Additionally, to deal with uncertainty and to test robustness of the model scenario, one-way and probabilistic sensitivity analyses were conducted. RESULTS: Implementing the program resulted in a quality-adjusted life year (QALY) gain of 0.14 in favor of the invention group compared with controls and an incremental cost of 1270€ from the third-party payer perspective and of 1220€ from the societal perspective. Next, an incremental cost-effectiveness ratio of 9042€/QALY and of 8690€/QALY was found in the base case, from the third-party payer perspective and the societal perspective, respectively. The scenario, one-way sensitivity, and probabilistic analyses demonstrated robustness of the base-case results. CONCLUSION: This cost-effectiveness analysis suggests that an in-home respite care program in addition to standard community-based dementia care is a cost-effective approach compared with standard community-based dementia care only. These findings provide more insight into the value of such services for the patient, the caregiver, and for society.

Effectiveness of an in-home respite care program to support informal dementia caregivers: A comparative study.

OBJECTIVES: Dementia is a major public health problem with important physical, psychosocial, emotional, and financial consequences for patients, their caregivers, and society. Since patients prefer to be managed at home, extensive research has been conducted into effectiveness of psychosocial interventions to support informal caregivers. The aim of this study was to assess the effectiveness of an in-home respite care program. METHODS: In a prospective quasi-experimental study, 99 dyads who received an in-home respite care program were compared at 6 months post-baseline, with 99 matched dyads receiving standard dementia care. Additionally, the short-term effect of the program was evaluated 14 to 15 days post-intervention. The primary outcome was caregiver burden. The secondary outcomes were: desire to institutionalize the patient, caregiver quality of life, and frequency and impact of behavioral problems. Mixed model analyses were performed to evaluate the impact of the intervention. RESULTS: After 6 months, no significant difference on caregiver burden was observed, but intervention group caregivers had a significant lower desire to institutionalize the patient compared with control group caregivers (adj.diff = -0.51; p = .02). Shortly after the program, intervention group caregivers also had a significant lower role strain (adj.diff = 0.75; p = .05), and a lower burden on social and family life (adj.diff = 0.55; p = .05) compared with baseline. CONCLUSIONS: This study was the first comparative study to investigate effectiveness of an in-home respite care program to support informal caregivers of persons with dementia. The results partly confirm earlier positive findings from explorative studies.

Factors Associated with the Caregivers' Desire to Institutionalize Persons with Dementia: A Cross-Sectional Study.

BACKGROUND/AIMS: Dementia is one of the main reasons for institutionalization among the elderly. Few studies have explored factors associated with the caregivers' (CG) desire to institutionalize (DTI) a person with dementia (PWD). The objective of this study is to identify modifiable and non-modifiable psychosocial and sociodemographic factors associated with a caregiver's DTI. METHODS: Cross-sectional data of 355 informal CG of community-dwelling PWD were analyzed. Several characteristics were identified in CG and PWD to be included in a multivariable regression model based on the purposeful selection method. RESULTS: Positively modifiable associated factors were: higher CG burden, being affected by behavioral problems, and respite care use. Positively associated non-modifiable factors were: CG older age, being professionally active, and CG higher educational level. Cohabitation and change of professional situation were negatively associated. CONCLUSION: Although no causality can be assumed, several practical recommendations can be suggested. First of all, these results reconfirm the importance of multicomponent strategies, especially support aimed at decreasing burden and in learning coping strategies. Also, CG might benefit from information about support options, such as respite care services. Finally, special attention should be given to older and working CG. In the latter, flexible and adaptive working conditions might alleviate burden and therefore reduce the DTI of the PWD.

Effectiveness and cost-effectiveness of an in-home respite care program in supporting informal caregivers of people with dementia: design of a comparative study.

BACKGROUND: Frequent hospitalization and permanent nursing home placement not only affect the well-being of persons with dementia, but also place great financial strain on society. Therefore, it is important to create effective strategies to support informal caregivers so that they can continue to perform their demanding role. Preliminary qualitative evidence suggests that community-based respite services can actually be important for caregivers, and that the level of evidence should be further established in terms of effectiveness. Therefore, a comparative study to assess the effectiveness and cost-effectiveness of an in-home respite care program will be initiated. METHODS: This manuscript described a quasi-experimental study to assess (cost)-effectiveness of an in-home respite care program to support informal caregivers of persons with dementia. STUDY POPULATION: 124 informal caregivers and persons with dementia will be included in the intervention group and will receive an in-home respite care program by an organization called Baluchon Alzheimer. 248 dyads will be included in the control group and will receive standard dementia care. The primary outcome is caregiver burden. Secondary outcomes are: quality of life of caregivers, frequency of behavioral problems of persons with dementia and the reactions of caregivers to those problems, intention to institutionalize the care-recipient, time to nursing home placement, resource use of the care-recipient, and willingness to pay for in-home respite care. When the trial demonstrates a difference in outcomes between both groups, within-trial and modeled cost-effectiveness analyses will be conducted in a separate economic evaluation plan to evaluate possible cost-effectiveness of the in-home respite care program compared to the control group receiving standard dementia care. Finally, the model based cost-effectiveness analyses will allow to extrapolate effects over a longer time horizon than the duration of the trial. DISCUSSION: This study will have great added value because to date no studies measured effectiveness and cost-effectiveness of an in-home respite care program of the Baluchon type. Results of this trial can thus give much more insight in potential benefits and disadvantages of community-based respite care. Conclusions based on this trial can help policy-makers in elaborating future directions of dementia care. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT02630446 .

Effectiveness of respite care in supporting informal caregivers of persons with dementia: a systematic review.

OBJECTIVE: Supporting informal caregivers of persons with dementia is considered to be an effective strategy for improving the well-being of caregivers and care recipients and for delaying nursing home placement. Although considerable research has been conducted to investigate the effectiveness of psychoeducational interventions, cognitive behavioral therapy, and occupational therapy, research into the effectiveness of respite care is rare. This systematic review aims to investigate the effectiveness of different types of respite care in supporting informal caregivers of persons with dementia. METHODS: A systematic literature search was conducted using Web of Science and PubMed, and the Quality Assessment Tool for Quantitative Studies was used to assess the methodological quality. Randomized controlled trials, quasi-experimental studies, pretest-posttest studies without a control group, and cohort studies were included. RESULTS: Seventeen papers met the inclusion criteria. Day care services are effective in decreasing caregiver burden and behavioral problems in persons with dementia, but they also accelerate time to nursing home admission. The results of temporary residential admission are rather mixed and show unexpected adverse effects on both caregivers and care recipients. High-quality comparable evidence on community-based respite care is still lacking, although earlier qualitative evidence indicated promising results. CONCLUSION: Unlike in previous reviews, we were able to draw some conclusions about the effectiveness of some types of respite care. There is nonetheless still a need for new intervention studies measuring the impact of respite care, especially in-home respite care programs, on the caregiver, the care recipient, and health care resource utilization.

Effectiveness of Supporting Informal Caregivers of People with Dementia: A Systematic Review of Randomized and Non-Randomized Controlled Trials.

BACKGROUND: Dementia is known as a major public health problem affecting both patients and caregivers, and placing a high financial strain upon society. In community-dwelling patients, it is important to support informal caregivers in order to help them sustain their demanding role. Previous reviews about effectiveness of such supporting strategies often included a small number of studies, focused only on particular supportive types, particular outcomes, or solely on caregivers. OBJECTIVE: A general systematic review was conducted investigating effectiveness of different supportive strategies on at least the well-being of the caregiver or the care-recipient. METHODS: A systematic literature search was conducted in Web of Science and PubMed. An adapted version of the Downs and Black (1998) checklist was used to assess methodological quality. A new classification was developed to group different types of caregiver support. RESULTS: Fifty-three papers met the inclusion criteria. Although 87% of the interventions were to some extent effective, methods and findings were rather inconsistent. Psychoeducational interventions generally lead to positive outcomes for caregivers, and delay permanent institutionalization of care-recipients. Cognitive behavioral therapy decreases dysfunctional thoughts among caregivers. Occupational therapy decreases behavioral problems among patients and improves self-efficacy of caregivers. In general, those interventions tailored on individual level generate better outcomes. Comparative research on respite care was very rare. CONCLUSIONS: Despite methodological inconsistency, supporting caregivers appears to be an effective strategy often improving well-being of caregiver or care-recipient and resulting in additional benefits for society. However, there is a need for more research on the (cost)-effectiveness of respite care.
