“…The intervention complexity of studies (intervention number and the interaction among interventions in a system’s structure) should be considered in the future, as a mixture of interventions should be applied to NH residents with a more accurate intervention estimation [ 74 ]. The interventions that were conducted to improve residents’ physical, psychological, and cognitive functions included fall prevention, nutrition, oral care, ambulant, feeding, exercise, and so on.…”

“…The interventions that were conducted to improve residents’ physical, psychological, and cognitive functions included fall prevention, nutrition, oral care, ambulant, feeding, exercise, and so on. Scholars should clearly define the research objectives, population to be studied, and scope of treatments when performing MAs to answer the research questions [ 74 ]. NHs have some unique characteristics to consider, such as (a) resident- and organizational-level factors, (b) lengthy resident stays in specific NHs, and (c) randomization.…”

(1) Background: The nursing home (NH) research field lacks quality reporting about meta-analyses (MAs), and most gradings of MA evidence are biased on analyzing the effectiveness of independent variables in randomized control trials. (2) Objectives: This study aimed to perform a critical methodological review of MAs in the NH research field. (3) Methods: We searched the articles from four databases (PubMed, MEDLINE, CINAHL, and PsycINFO) until 15th January 2021. We reviewed a total of 41 published review articles in the NH research field. (4) Results: The studies primarily fell into the following categories: medicine (17/41), nursing (7/41), and psychiatry or psychology (6/41); 36.6% of the reviewed studies did not use any validated MA guidelines. The lowest correctly reported PRISMA 2000 guideline item was protocol and registration (14.6%), and more than 50% of articles did not report risk of bias. Moreover, 78.0% of studies did not describe missing reports of effect size formula. (5) Discussion: NH researchers must follow appropriate and updated guidelines for their MAs in order to provide validated reviews, as well as consider statistical issues such as the complexity of interventions, proper grouping, and scientific effect-size calculations to improve the quality of their study. Future quality review studies should investigate more diverse studies.

“…This alludes to the fact that interventions are most effective when they take a systems approach and target multiple stakeholders at different stages of change 37 . As noted above, interventions investigated in this umbrella review are known to be context‐dependent 38 . Contextual factors that can mediate effectiveness include organisational characteristics, strategic approaches to, and resourcing of, implementation, the degree of support by organisational leaders, and local organisational and disciplinary cultures 10 .…”

To conduct a systematic synthesis of existing evidence reviews on interventions to enhance medication safety in residential aged-care settings (RACS) to establish and compare their effectiveness.Method: This umbrella review included examination of meta-analyses, scoping and systematic reviews. Four electronic databases were examined for eligible reviews.Two authors critically appraised those meeting the inclusion criteria using the Joanna Briggs Institute Critical Appraisal Instrument. Results: Fifteen reviews covering 171 unique, primary studies were included. Of the variety of interventions identified in the literature, five main categories of interventions were commonly reported to be effective in promoting medication safety in RACS (medication review, staff education, multidisciplinary team meetings, computerised clinical decision support systems and miscellaneous). Most reviews showed mixed evidence to support intervention effectiveness due to the significant heterogeneity between studies in their sites, sample sizes and intervention periods. In all intervention categories, pharmacists' collaboration was most beneficial, showing definitive evidence for improving medication safety and quality of prescribing in RACS. Eight reviews recommended multicomponent interventions, particularly medication reviews and staff education, but specific details were infrequently provided. Only five reviews presented insights into implementation facilitators and barriers, while the sustainability of interventions was only discussed in one review. Conclusion: There is strong evidence to support the four main categories of interventions identified. However, limited details are available regarding the most appropriate design and implementation of multicomponent interventions and the sustainability of all interventions, thus solid recommendations cannot be made. Future research in this field should focus on producing theoretically informed, methodologically robust, original research, particularly regarding the design, implementation and sustainability of multicomponent interventions, which appears the most promising approach.

“…The lack of top-quality health economics research on low-income countries is of great concern. These countries face the highest disease burdens globally and have extremely limited resources to finance health R&D. Moreover, research findings from richer countries are rarely exportable to low-income country settings because the estimated intervention effects and costs are often mediated 10 or moderated 11 by the context in which the study occurred (Anderson, 2010;Thomas et al, 2019). These concerns extend to economic experiments conducted in laboratory settings (Levitt & List, 2007).…”

The Journal of Health Economics and Health Economics are arguably the top two journals in the field of health economics. Together, they published 1,679 empirical research articles in the past decade (2010–2019). In line with analyses based on earlier periods, the empirical evidence in top health economics journals continues to be dominated by the United States (37% of all empirical articles), whereas studies based on low‐income countries remain rare (2%). Countries with higher disease burdens receive generally less attention from health economists publishing at the top of their field. Reflecting this, more research was published based on data from the Nordic countries (27 million people) than from sub‐Saharan Africa and South Asia regions combined (2.9 billion people). Finally, one‐third of the empirical articles did not indicate the country of evidence in the title or the abstract, possibly to signal external validity of the findings. This practice was particularly common for articles based on data from North America with more than half of the articles omitting the country of evidence from the title and the abstract. The study concludes by exploring some hypotheses that may explain these findings.
