BACKGROUND: Multiple systematic reviews examine the introduction of foods in relation to individual health outcomes, but the balance of harms and benefits has not been overviewed systematically. OBJECTIVES: We aimed to perform an overview of systematic reviews on age of introduction of complementary and allergenic foods to the infant diet and long and short-term health outcomes. DATA SOURCES: We searched Medline, Embase, Cochrane, and PubMed (July 25, 2022). STUDY SELECTION: Included systematic reviews examining the introduction of complementary or allergenic foods before age 1. Outcomes included allergic, autoimmune, and inflammatory diseases, neurodevelopment, nutrition, and weight. DATA EXTRACTION: Extraction and quality assessment were performed in duplicate (A Measurement Tool to Assess Systematic Reviews) and strength of evidence was assessed. RESULTS: We screened 4015 articles and included 32 systematic reviews. There was moderate evidence that peanut and egg should be introduced from 4 to 11 months to prevent food allergy (6 of 10 reviews). Complementary food introduction was not associated with food allergy. Moderate certainty evidence suggested age of complementary food introduction was not associated with eczema. Age at introduction of gluten was not associated with celiac disease (high certainty evidence; 3 of 4 reviews). Low certainty evidence indicated that introducing solids before 4 months may increase the risk of childhood obesity, but not growth. There was insufficient evidence regarding an association between any food introduction and bone health, gastrointestinal diseases, autoimmune disorders, asthma, or allergic rhinitis. LIMITATIONS: Gray literature was not included. CONCLUSIONS: Current evidence supports introducing complementary foods around 6 months and allergenic foods before 11 months.

Objective: To summarise and critically appraise systematic review (SR) evidence on the effects of timing of complementary feeding (CF) on the occurrence of allergic sensitisation and disease. Design: Overview of SRs. AMSTAR-2 and ROBIS were used to assess methodological quality and risk of bias (RoB) of SRs. RoB 2 Tool was used to assess RoB of primary randomised controlled trials (RCTs) (or extracted). The certainty of evidence (CoE) was assessed using GRADE. Findings were synthesised narratively. Data Sources: MEDLINE (via PubMed and Ovid), the Cochrane Library and Web of Science Core Collection (2010 to 27 February 2023). Eligibility Criteria: SRs investigating the effects of timing of CF in infants or young children (0–3 years) on risk of developing food allergy (FA), allergic sensitisation, asthma, allergic rhinitis, atopic eczema and adverse events based on RCT evidence. Results: Eleven SRs were included. Only two SRs had low RoB; common issues were failure to report on funding of primary studies and failure to provide a list of excluded trials. Common limitations of included trials were lack of blinding of outcome assessment or detailed trial preregistration, and inadequate handling of high loss to follow up. Primary study overlap was very high for specific FA and slight to moderate for FA in general and other primary outcomes. Introducing specific foods (peanut, cooked egg) early probably reduces the risk of specific FA. Evidence for other allergic outcomes was mostly very uncertain and based on few primary studies. Trials varied regarding timing of CF, nature of complementary foods and population risk, which limited comparability between SRs. Conclusions: For developing guidelines to support decision-making on the timing of CF as a preventive strategy, early introduction of specific foods (i.e. egg and peanut) seems promising and safe, whereas more extensive research is required regarding other allergic outcomes and potential adverse events. © 2023 The Authors.

BACKGROUND: As a source of readily available evidence, rigorously synthesized and interpreted by expert clinicians and methodologists, clinical guidelines are part of an evidence-based practice toolkit, which, transformed into practice recommendations, have the potential to improve both the process of care and patient outcomes. In Brazil, the process of development and updating of the clinical guidelines for the Brazilian Unified Health System (Sistema Único de Saúde, SUS) is already well systematized by the Ministry of Health. However, the implementation process of those guidelines has not yet been discussed and well structured. Therefore, the first step of this project and the primary objective of this study was to summarize the evidence on the effectiveness of strategies used to promote clinical practice guideline implementation and dissemination. METHODS: This overview used systematic review methodology to locate and evaluate published systematic reviews regarding strategies for clinical practice guideline implementation and adhered to the PRISMA guidelines for systematic review (PRISMA). RESULTS: This overview identified 36 systematic reviews regarding 30 strategies targeting healthcare organizations, healthcare providers and patients to promote guideline implementation. The most reported interventions were educational materials, educational meetings, reminders, academic detailing and audit and feedback. Care pathways-single intervention, educational meeting-single intervention, organizational culture, and audit and feedback-both strategies implemented in combination with others-were strategies categorized as generally effective from the systematic reviews. In the meta-analyses, when used alone, organizational culture, educational intervention and reminders proved to be effective in promoting physicians' adherence to the guidelines. When used in conjunction with other strategies, organizational culture also proved to be effective. For patient-related outcomes, education intervention showed effective results for disease target results at a short and long term. CONCLUSION: This overview provides a broad summary of the best evidence on guideline implementation. Even if the included literature highlights the various limitations related to the lack of standardization, the methodological quality of the studies, and especially the lack of conclusion about the superiority of one strategy over another, the summary of the results provided by this study provides information on strategies that have been most widely studied in the last few years and their effectiveness in the context in which they were applied. Therefore, this panorama can support strategy decision-making adequate for SUS and other health systems, seeking to positively impact on the appropriate use of guidelines, healthcare outcomes and the sustainability of the SUS.

BACKGROUND & OBJECTIVE: It has been suggested that prenatal vitamin D plays a role in the development of childhood asthma and wheeze. Several systematic reviews have been conducted, but the results are inconsistent, and the methodological quality has not been studied. Therefore, the objective of this umbrella review was to assess the internal validity of the evidence base and the evidence for an association between prenatal vitamin D and asthma or wheezing in the offspring. METHODS: We searched the electronic databases Embase, PubMed, and Cochrane Library for studies on prenatal vitamin D using search words such as vitamin D, 25-hydroxyvitamin D, calcidiol, fetal, and neonatal. The search was conducted in June 2020, and the databases were searched from their date of establishment. We included systematic reviews and/or meta-analyses of experimental and observational studies assessing the association between prenatal vitamin D or asthma and wheeze. We excluded narrative reviews, commentaries, and other umbrella reviews. The methodological quality of systematic reviews was assessed using AMSTAR 2 tool. PROSPERO reg. no. CRD42020151329. RESULTS: We identified 22 eligible systematic reviews (17 on asthma and 20 on wheeze). Using the AMSTAR 2 quality assessment tool, the methodological quality was rated as critically low in 21 out of 22 systematic reviews, suggesting that previous reviews and meta-analyses did not provide accurate and comprehensive summaries of the included studies and that conclusions reached were potentially flawed. The majority of the included reviews reported that prenatal vitamin D reduces the risk of wheeze in the offspring. CONCLUSION: Prior to informing public guidelines, high-quality systematic reviews of the current evidence are greatly warranted.

BACKGROUND: The underuse or overuse of knowledge products leads to waste in healthcare, and primary care is no exception. OBJECTIVE: We aimed to characterize which knowledge products are frequently implemented, the implementation strategies used in primary care, and the implementation outcomes that are measured. METHODS: We performed a systematic review of systematic reviews (SR) using the Cochrane systematic approach to include eligible SR. The inclusion criteria were: any primary care contexts; healthcare professionals and patients; any EPOC implementation strategies of specified knowledge products; any comparator; and any implementation outcomes based on the Proctor framework. We searched the Medline, EMBASE, CINAHL, Ovid PsycINFO, Web of Science, and Cochrane Library databases from their inception to October 2019, without any restriction. We searched the references of the included SR. Pairs of reviewers independently performed selection, data extraction and methodological quality assessment with AMSTAR 2. Data extraction was informed by EPOC taxonomy for implementation strategies and the Proctor framework for implementation outcomes. We performed a descriptive analysis and summarized the results using a narrative synthesis. RESULTS: Of the 11,101 records identified, 81 SR were included. Forty-seven SR involved healthcare professionals alone. Fifteen SR were of high or moderate methodological quality. Most of them addressed one type of knowledge product (56/81), common clinical practice guidelines (26/56) or management, and behavioural or pharmacological health interventions (24/56). Mixed strategies were used for implementation (67/81), predominantly educational-based (meetings in 60/81, materials distribution in 59/81, and academic detailing in 45/81), reminder (53/81) and audit and feedback (40/81) strategies. Education meetings (P=.13) and academic detailing (P=.11) seem to be more used when the population is composed of Healthcare professionals alone. The improvement of the adoption of knowledge products was the most commonly measured outcome (72/81). The evidence level was reported in 10/81 SR on 62 outcomes (including 48 improvement of adoption), of which 16 outcomes were of moderate or high level. CONCLUSIONS: Clinical practice guidelines and management, behavioural or pharmacological health interventions are the most commonly implemented knowledge products through the mixed use of educational, reminders and audit and feedback strategies. There is need for a strong methodology for the SR of RCTs to explore their effectiveness and the whole cascade of implementation outcomes. CLINICALTRIAL: Not applicable.

OBJECTIVE To present an overview of systematic reviews on throughput interventions to solve the overcrowding of emergency departments. METHODS Electronic searches for reviews published between 2007 and 2018 were made on PubMed, Cochrane Library, EMBASE, Health Systems Evidence, CINAHL, SciELO, LILACS, Google Scholar and the CAPES periodicals portal. Data of the included studies was extracted into a pre-formatted sheet and their methodological quality was assessed using AMSTAR 2 tool. Eventually, 15 systematic reviews were included for the narrative synthesis. RESULTS The interventions were grouped into four categories: (1) strengthening of the triage service; (2) strengthening of the ED's team; (3) creation of new care zones; (4) change in ED's work processes. All studies observed positive effect on patient's length of stay, expect for one, which had positive effect on other indicators. According to AMSTAR 2 criteria, eight revisions were considered of high or moderate methodological quality and seven, low or critically low quality. There was a clear improvement in the quality of the studies, with an improvement in focus and methodology after two decades of systematic studies on the subject. CONCLUSIONS Despite some limitations, the evidence presented on this overview can be considered the cutting edge of current scientific knowledge on the topic.

AIM: Integrated care commonly involves provision of comprehensive community-based care for people with chronic conditions. It is anticipated that implementation of integrated care, with a proactive approach to management of chronic conditions, will reduce reliance on hospital and emergency department (ED) services. The aim of this rapid review was to summarize the best available evidence on the impact of integrated care for patients with chronic conditions on hospital and ED utilization and investigate trends in outcomes over time. METHODS: Given the large body of literature available on this topic, this rapid review considered existing systematic reviews and meta-analyses that included adults with chronic conditions. Any model of integrated care that involved management of patients across the continuum of care, with the aim to provide more care in community settings, was considered for inclusion. A search of PubMed, CINAHL, Google Advanced, and websites of international healthcare provider organizations was conducted to locate relevant published and gray literature. RESULTS: A total of 13 systematic reviews were included. Overall, evidence suggests that integrated care may reduce the risk of hospitalization, with reviews including patients with diverse chronic conditions showing a 19% reduction. Integrated care appears effective in reducing readmissions for patients with heart failure, with an absolute risk reduction of 8% for first and 19% for subsequent rehospitalization. For ED presentations, evidence indicates that integrated care has no effect overall but may reduce ED visits for patients aged 65 years or more. For patients with chronic obstructive pulmonary disease, integrated care was associated with reductions in length of stay ranging from 2.5 to 4 days. Studies with shorter follow-up, from 3 to 12 months, in general appeared to show a greater impact of integrated care than studies with longer follow-up of 18 months or more. CONCLUSION: The evidence identified suggests integrated care generally reduces utilization of hospital services. In some instances, there were no differences observed between integrated care and usual care, but no included reviews reported increased utilization of these services. The impact of integrated care may be greater in the short-term, given the ultimate deterioration associated with advanced chronic disease which may negate any long-term benefits.

BACKGROUND: Current interventions to support medication adherence in people with type 2 diabetes are generally resource-intensive and ineffective. Brief messages, such as those delivered via short message service (SMS) systems, are increasingly used in digital health interventions to support adherence because they can be delivered on a wide scale and at low cost. The content of SMS text messages is a crucial intervention feature for promoting behavior change, but it is often unclear what the rationale is for chosen wording or any underlying mechanisms targeted for behavioral change. There is little guidance for developing and optimizing brief message content for use in mobile device-delivered interventions. OBJECTIVE: This review aimed to (1) identify theoretical constructs (ie, the targets that interventions aim to change) and behavioral strategies (ie, features of intervention content) found to be associated with medication adherence in patients with type 2 diabetes and (2) map these onto a standard taxonomy for behavior change techniques (BCTs, that is, active ingredients of interventions used to promote behavioral change, to produce an evidence-based set of approaches that have shown promise of improving adherence in previous studies and which could be further tested in digital health interventions. METHODS: A rapid systematic review of existing relevant systematic reviews was conducted. MEDLINE and PsycINFO databases were searched from inception to April 10, 2017. Inclusion criteria were (1) systematic reviews of quantitative data if the studies reviewed identified predictors of or correlates with medication adherence or evaluated medication adherence-enhancing interventions and included adult participants taking medication to manage a chronic physical health condition, and (2) systematic reviews of qualitative studies of experiences of medication adherence for adult participants with type 2 diabetes. Data were extracted on review characteristics and BCTs, theoretical constructs, or behavioral strategies associated with improved adherence. Constructs and strategies were mapped onto the BCT version 1 taxonomy. RESULTS: A total of 1701 references were identified; 25 systematic reviews (19 quantitative reviews, 3 qualitative reviews, and 3 mixed-method reviews) were included. Moreover, 20 theoretical constructs (eg, self-efficacy) and 19 behavioral strategies (eg, habit analysis) were identified in the included reviews. In total, 46 BCTs were identified as being related to medication adherence in type 2 diabetes (eg, habit formation, prompts or cues, and information about health consequences). CONCLUSIONS: We identified 46 promising BCTs related to medication adherence in type 2 diabetes on which the content of brief messages delivered through mobile devices to improve adherence could be based. By using explicit systematic review methods and linking our findings to a standardized taxonomy of BCTs, we have described a novel approach for the development of digital message content. Future brief message interventions that aim to support medication adherence could incorporate the identified BCTs.

OBJECTIVES: Globally, healthcare policy promotes supported self-management as a strategy for people with long-term conditions. This meta-review aimed to explore how people with hypertension make sense of their condition, to assess the effectiveness of supported self-management in hypertension, and to identify effective components of support. METHODS: From a search of eight databases (January 1993-October 2012; update June 2017) we included systematic syntheses of qualitative studies of patients' experiences, and systematic reviews of randomized controlled trials evaluating the impact of supported self-management on blood pressure and medication adherence. We used meta-ethnography, meta-Forest plots and narrative analysis to synthesise the data. RESULTS: Six qualitative and 29 quantitative reviews provided data from 98 and 446 unique studies, respectively. Self-management support consistently reduced SBP (by between 2 and 6 mmHg), and DBP (by between 1 and 5 mmHg). Information about hypertension and treatment, home BP monitoring (HBPM) and feedback (including telehealth) were widely used in effective interventions. Patients' perceptions of a disease with multiple symptoms contrasted with the professional view of an asymptomatic condition. HBPM, in the context of a supportive patient-professional relationship, changed perceptions of the significance of symptoms and fostered confidence in ability to self-manage hypertension. CONCLUSION: Our systematic qualitative and quantitative meta-reviews tell complementary stories. Supported self-management can improve blood pressure control. Interventions are complex and encompass a broad range of support strategies. HBPM (with or without telehealth) within the context of a supportive patient-professional partnership can bridge the gap between medical and lay perspectives of hypertension and enable effective self-management.

IMPORTANCE: Medical overuse has historically focused on adult health care, but interest in how children are affected by medical overuse is increasing. This review examines important research articles published in 2016 that address pediatric overuse. OBSERVATIONS: A structured search of PubMed and a manual review of the tables of contents of 10 journals identified 169 articles related to pediatric overuse published in 2016, from which 8 were selected based on the quality of methods and potential harm to patients in terms of prevalence and magnitude. Articles were categorized by overtreatment, overmedicalization, and overdiagnosis. Findings included evidence of overtreatment with commercial rehydration solution, antidepressants, and parenteral nutrition; overmedicalization with planned early deliveries, immobilization of ankle injuries, and use of hydrolyzed infant formula; and evidence of overdiagnosis of hypoxemia among children recovering from bronchiolitis. CONCLUSIONS AND RELEVANCE: The articles were of high quality, with most based on randomized clinical trials. The potential harms associated with pediatric overuse were significant, including increased risk of infection, developmental disability, and suicidality.
