Background: One of the most commonly used types of evaluation methods is cost-utility analysis (CUA), using the Quality Adjusted Life Year (QALY) indicator as a preference-based measure for assessing effects of a given programme. Such assessments are often translated into health-care provision priorities; therefore, effectively choosing the method of outcome evaluation is crucial for ensuring the best possible allocation of scarce resources. The main objective of this scoping review is to identify what kinds of problems and limitations may occur when the QALY indicator is used to assess the effects of health interventions in the older population. Methods: To identify literature in a scoping review, the databases MEDLINE via PubMed and Scopus were searched. A manual search on relevant organizations’ and associations’ websites was also conducted (EUnetHTA, ISPOR and national governmental agencies responsible for allocation decisions). No limits concerning publication dates were set. All relevant data were extracted and analyzed, then a narrative summary was prepared. Results: The database search identified 10,832 relevant items, finally 32 studies were included in the analysis. The main types of issues indicated in the studies were as follows: (1) lower life expectancy in the older population causes lower QALY gains; (2) an equal value of one QALY is used regardless of age; (3) poorer average health state causes lower QALY gains; (4) inadequate instruments to measure quality of life (QoL); (5) attributes of QoL used regardless of age; and (6) no beyond-health QoL aspects taken into account. Conclusions: This review shows clearly that many problems of different types are connected with using QALY for the older population, but there is no consensus as to whether QALY discriminates against the older population or not – an opinion regarding this issue depends strongly on accepted principles, particularly the approach to equity and how one understands fairness. Health care resources should not be allocated solely on the basis of the health maximization rule because this can lead to discrimination against certain groups (e.g., older, disabled, and/or chronically ill people). To maintain the balance between efficiency and equity, the issues connected with age-based rationing should be widely discussed.

Background: Healthy ageing and health promotion (HP) actions for older people have become an important health sector priority. At the same time, the application of economic evaluation methods in the field of health interventions in order to support allocative decision processes is of growing importance. The aims of the review were to analyze what the existing evidence is on cost-effectiveness of HP and/or primary prevention (PP) programmes for older people whilst providing deeper insight into methodological aspects of such studies, their overall quality and issues related to practical implementation of results. Methods: Systematic review of contemporary evidence (2000–15). Studies’ eligibility criteria included target population 65 years old or older; interventions classified as HP or PP; a full economic evaluation conducted. The search strategy included five electronic databases and Internet websites of institutions or projects related to the topic. Quality assessment of the studies was based on the ‘Drummond checklist’. Results: After screening 6450 records, 29 papers were included, the vast majority of which (22) focus on fall prevention strategies. In this area, there are examples of good and moderate quality studies which confirm the cost-effectiveness of diverse physical activity interventions in fall prevention. The existing studies are characterized by huge differences in the methods applied as well as overall quality which limits the comparability and generalizability of the results. Conclusions: There is a need for development and implementation of economically driven studies, with methods adjusted to particular character of HP and/or PP strategies for older population.

The support of health promotion activities for older people gains societal relevance in terms of enhancing the health and well-being of older people with a view to the efficient use of financial resources in the healthcare sector. Health economic evaluations have become an important instrument to support decision-making processes in many countries. Sound evidence on the cost-effectiveness of health promotion activities would encourage support for the implementation of health promotion activities for older people. This debate article discusses to what extent economic evaluation techniques are appropriate to support decision makers in the allocation of resources regarding health promotion activities for older people. We address the problem that the economic evaluation of these interventions is hampered by methodological obstacles that limit comparability, e.g. with economic evaluations of curative measures. Our central objective is to describe and discuss the specific problems and challenges entailed in the economic evaluation of health promotion activities especially for older people with regard to their usefulness for informing decision making processes. Beyond general problems concerning the economic evaluation of health promotion, our discussion focusses on problems that pertain to the analysis of cost and outcomes of health promotion interventions for older people. With regard to costs these are general problems of economic evaluations, namely the actual implementation of a societal perspective, the appropriate measurement and valuation of informal caregiver time, the measurement and valuation of productivity costs and costs incurred in added years of life. The main problems concerning the identification and measurement of outcomes are related to the identification of outcome parameters that, firstly, adequately reflect the broad effects of health promotion interventions, especially social benefits that gain importance for older people, and secondly, ensure a comparability of effects across different age groups. In particular, the limitations of the widely used QALY for older people are discussed and recently developed alternatives are presented. The key conclusion of the article is that a comparison of the effects of different health promotion initiatives between different age groups by means of economic evaluation is not recommendable. Taking into account the complex outcomes of health promotion interventions it has to be accepted that the outcomes of these interventions will often not be comparable with clinical interventions and have to be assessed differently.

Background: Improving the quality of hospital care is an important policy objective. Hospitals operate under pressure to contain costs and might face challenges related to financial deficits. The objective of this paper was to identify and map the available evidence on the association between hospital financial performance (FP) and quality of care (Q). Methods: A scoping review was performed. Searches were conducted in 7 databases: Medline via PubMed, EMBASE, Web of Science, Scopus, EconLit, ABI/INFORM, and Business Source Complete. The search strategy combined multiple terms from 3 topics: hospital AND FP AND Q. The collected data were analysed using both quantitative and qualitative methods. Results: 10 503 records were screened and 151 full text papers analysed. A total of 69 papers were included (60 empirical, 2 theoretical, 5 literature reviews, and 2 dissertations). The majority of identified studies were published within the last decade (2010-2021). Most empirical studies had been conducted in the United States (55/60), used cross-sectional approaches (32/60) and applied diverse regression models with FP measures as dependent variables, thus measuring the impact of Q on hospitals FP (34/60). The comparability of the studies’ results is limited due to differences in applied methods and settings. Yet, the general overview shows that in almost half of the cases the association between hospital FP and Q was positive, while no study showed a clear negative association. Conclusion: This scoping review provides an overview of the available literature on the association between hospital FP and Q. The results highlight numerous research gaps: (1) systematic reviews and meta-analyses of existing studies with similar measures of FP and Q are unavailable, (2) further methodological/conceptual work is needed on the metrics measuring hospital FP and Q, and (3) more empirical studies should analyse the association between FP and Q in nonUS healthcare settings.

There is growing evidence of a positive association between health care providers’ financial standing and the quality of care. In Poland, the instable financial situation and growing debt of public hospitals has been a source of concern for more than two decades now. The objectives of this paper were to compare the financial performance of public hospitals in Poland, depending on the ownership and organizational form; and analyze whether there is an association between financial performance and the chosen variables. We conducted a cross sectional study covering the whole population of public hospitals operating in 2018. The total number of included units was 805. The hospitals’ financial outcomes were measured by several variables; Spearman’s rank correlation was calculated, and a multivariable logistic regression model was performed. In 2018, the majority of public hospitals in Poland (52%) generated a gross loss, while 40% hospitals had overdue liabilities. There were statistically significant differences between hospital groups, with university hospitals and those owned by counties (local hospitals) being in the most disadvantageous situation. Additionally, corporatized public hospitals performed worse than those functioning in the classic legal form of independent health care units. Urgent actions are needed to measure and monitor the potential impact of financial performance on the quality of care.

Background: Hospitals operate under constant pressure to contain costs and improve the quality of care. The literature suggests that there is an association between health care providers’ financial performance and the quality of care. On the one hand, providers that are financially more stable might have better capacity to maintain reliable systems and resources for quality improvement. On the other hand, providing better quality of care might lead to financial gains in the form of increased revenues or achieved savings and, in consequence, a higher profitability. The general objective of this scoping review is to identify and map the available evidence on the association between hospital financial performance and the quality of care. It aims to (1) provide a broad overview of the topic and (2) indicate a more precise research question for a future systematic review.Methods: This scoping review will follow five stages: (1) defining the research question; (2) identifying relevant literature; (3) study selection; (4) data extraction; (5) collating, summarizing, and reporting the results; and (6) the consultation process and engagement of knowledge users. The following databases will be searched: MEDLINE via PubMed, (2) EMBASE, (3) Web of Science, (4) Scopus, (5) EconLit, (6) ABI/INFORM, and (7) Business Source Premier. The reference lists of relevant papers will be visually scanned with the aim of identifying further studies of interest. Also, a gray literature search will be conducted by screening the websites of diverse organizations dealing with hospital performance and/or quality of care. The review will not apply a publication date limit and will include both quantitative and qualitative empirical studies as well as theoretical papers, technical reports, books/chapters, and thesis. The reporting will utilize the PRISMA extension for a Scoping Review checklist.Discussion: This scoping review will provide an overview of the existing literature on the association between hospital financial performance and the quality of care. The review process will apply a rigorous methodological approach while broad inclusion criteria should assure comprehensive coverage of the available literature. The main limitation of the review is related to the general limitation of scoping reviews, i.e., the lack of a systematic quality and risk of bias assessment of included studies. In addition, the review will include only publications in English.Systematic review registration: Open Science Frameworkosf.io/z25ag
