Systematic Review of Health Literacy in Childhood Cancer Patients, Survivors, and Their Caregivers

Abstract Objective This systematic review examined the literature regarding health literacy among pediatric cancer patients, survivors, and their caregivers. Specific aims were to identify and summarize measures used, levels of and demographic correlates of health literacy, effects of health literacy interventions, and associations between health literacy and health outcomes. Methods The search strategy was executed in the following databases: PubMed, EMBASE, PsycINFO, CINAHL, ERIC, and the Cochrane Library. Of the 842 unique studies retrieved, 9 met the inclusion criteria and were included in the systematic review. Results Studies used a variety of validated and study-specific measures with no measure emerging as the standard. Levels of health literacy were typically assessed subjectively and across studies the majority of those sampled self-reported adequate health literacy. Few studies examined demographic correlates of health literacy, precluding the identification of consistent predictors. Health literacy intervention research for this population is in its infancy and only pilot projects were identified; effects could not be evaluated. No studies assessed the impact of health literacy on health outcomes. Conclusions Very few studies assessed health literacy in pediatric oncology. As treatment for childhood cancer becomes increasingly complex, and patients and caregivers are expected to have adequate understanding of health information, health literacy is a critical construct that should not be overlooked.

The Impact

IntroductionForgetting to take a medication is the most common reason for non-adherence to self-administered medication. Dose administration aids (DAAs) are a simple and common solution to improve unintentional non-adherence for oral tablets. DAAs can be in the form of compartmentalised pill boxes, automated medication dispensing devices, blister packs and sachets packets. This protocol aims to outline the methods that will be used in a systematic review of the current literature to assess the impact of DAAs on adherence to medications and health outcomes.Methods and analysisRandomised controlled trials will be identified through electronic searches in databases including EMBASE, MEDLINE, CINAHL and the Cochrane Library, from the beginning of each database until January 2020. Two reviewers will independently screen studies and extract data using the standardised forms. Data extracted will include general study information, characteristics of the study, participant characteristics, intervention characteristics and outcomes. Primary outcome is to assess the effects of DAAs on medication adherence. Secondary outcome is to evaluate the changes in health outcomes. The risk of bias will be ascertained by two reviewers in parallel using The Cochrane Risk of Bias Tool. A meta-analysis will be performed if data are homogenous.Ethics and disseminationEthics approval will not be required for this study. The results of the review described within this protocol will be disseminated through publication in a peer-reviewed journal and relevant conference presentations.PROSPERO registration numberCRD42018096087

Abstract Background: Epoetin (EPO), darbepoetin (DARB) and red blood cell transfusions (RBCT) are therapeutic alternatives to treat anemia associated with cancer and cancer therapy. Results of randomized controlled trials (RCTs) conflict, and some question the safety of EPO and DARB. Previously, we systematically reviewed this topic (Bohlius et al, JNCI 2005). Since then many new studies became available necessitating an update the prior systematic review. Objectives: To determine the effectiveness and safety of recombinant human erythropoietin and darbepoetin to prevent or alleviate anemia in cancer patients (pts), and to compare current and previous results of systematic review. Methods: Included RCTs compared EPO or DARB plus RBCT if needed with observation plus RBCT for prophylaxis or treatment of anemia in cancer patients receiving or not receiving antineoplastic therapy. Patients had solid tumors or hematological malignancies including MDS. Endpoints were rates of RBCT, hematological response (defined as transfusion free Hb increase of 2 g/dL), tumor response, overall survival and thrombo embolic events. Medical databases (Cochrane Library, MEDLINE, EMBASE) and conference proceedings were searched (first review:1985–2001, update up to 04/2005). We included full-text and abstract publications plus unpublished data. Data extraction and quality assessment were in duplicate. Results: The update included 57 trials with 9,353 patients. Use of EPO or DARB significantly reduced the relative risk (RR) of RBCTs (RR 0.64; 95%-CI 0.60–0.68; 42 trials, n = 6,510). On average, participants in the EPO/DARB groups received one unit of blood less than controls (weighted mean difference −1.05; 95% CI− 1.32 −0.78; 14 trials, n = 2,353). Hb response (baseline Hb < 12 g/dL) was more likely in the EPO/DARB group (RR 3.43; 95%-CI 3.07–3.84; 22 trials, n = 4,307). Thrombo embolic complications were more frequent in patients receiving EPO/DARB: RR 1.67 (95%-CI 1.35–2.06; 35 trials, n = 6,769). Uncertainties remain whether and how EPO/DARB affects tumor response (fixed effect RR 1.12; 95%-CI 1.01–1.23; random effects: RR 1.09; 95%-CI 0.94–1.26; 13 trials, n = 2,833) or overall survival (HR 1.08; 95%-CI 0.99–1.18; 42 trials, n = 8,167). Subgroup analyses comparing EPO and DARB did not identify clinically or statistically significant differences. This update confirms previous findings for transfusion rates and hematological response. In contrast, the update suggests EPO/DARB may reduce survival whereas the first review suggested possible benefits (HR 0.81; 95%-CI 0.67–0.99; 19 trials, n = 2,865). Factors possibly contributing to these conflicting results include mortality due to thrombo embolic complications and tumor progression but also methodological limitations such as baseline imbalances. Conclusion: EPO or DARB given to cancer pts reduces the relative risk for red blood cell transfusion and increases likelihood of hematological response. However, EPO/DARB also increases the risk of thrombo embolic complications. The impact on tumor response and survival is uncertain.

The Impact

The impact of ABO blood type in the development of venous thromboembolism in cancer patients remains controversial. To develop a sense of the current opinion in this area, we conducted a systematic review and meta-analysis. In March 2021, we performed a systematic search of PubMed, the Cochrane library, and Scopus for studies that compared cancer patients who had a blood type of either O or non-O (A, B, and AB). Our objective was to use multivariate logistic regression analysis to determine how ABO blood type was associated with the development of venous thromboembolism. Our selection criteria were met by a total of nine studies in 25,884 patients for the systematic review and five studies in 22,777 patients for the meta-analysis. In cancer patients, we found that non-O blood type was associated with a nearly two-fold increase in risk of venous thromboembolism (pooled OR: 1.74, 95% CI: 1.44–2.10). Additionally, among the eligible patients, 21,889 patients were post-operative urological cancer patients. In these patients, the analysis also showed an association between non-O blood type and increasing risk of venous thromboembolism after pelvic surgery for malignancy (pooled OR: 1.73, 95% CI: 1.36–2.20). Our meta-analysis suggested that non-O blood type is a risk factor for venous thromboembolism among patients with cancer. As blood type is routinely determined preoperatively by objective and standardized methods, we anticipate that our results will be useful for managing venous thromboembolism in cancer patients, especially after pelvic surgery for urological cancers.

The Impact

BackgroundGPs often act as gatekeepers, authorising patients’ access to specialty care. Gatekeeping is frequently perceived as lowering health service use and health expenditure. However, there is little evidence suggesting that gatekeeping is more beneficial than direct access in terms of patient- and health-related outcomes.AimTo establish the impact of GP gatekeeping on quality of care, health use and expenditure, and health outcomes and patient satisfaction.Design and settingA systematic review.MethodThe databases MEDLINE, PreMEDLINE, Embase, and the Cochrane Library were searched for relevant articles using a search strategy. Two authors independently screened search results and assessed the quality of studies.ResultsElectronic searches identified 4899 studies (after removing duplicates), of which 25 met the inclusion criteria. Gatekeeping was associated with better quality of care and appropriate referral for further hospital visits and investigation. However, one study reported unfavourable outcomes for patients with cancer under gatekeeping, and some concerns were raised about the accuracy of diagnoses made by gatekeepers. Gatekeeping resulted in fewer hospitalisations and use of specialist care, but inevitably was associated with more primary care visits. Patients were less satisfied with gatekeeping than direct-access systems.ConclusionGatekeeping was associated with lower healthcare use and expenditure, and better quality of care, but with lower patient satisfaction. Survival rate of patients with cancer in gatekeeping schemes was significantly lower than those in direct access, although primary care gatekeeping was not otherwise associated with delayed patient referral. The long-term outcomes of gatekeeping arrangements should be carefully studied before devising new gatekeeping policies.

Abstract Background Aboriginal and Torres Strait Islander peoples continue to experience poorer health outcomes than other population groups. While data specific to Indigenous Australians are scarce, a known social health literacy gradient exists linking low health literacy and poor health outcomes within many minority populations. Improving health literacy among Indigenous Australians is an important way to support self-determination and autonomy in both individuals and communities, by enhancing knowledge and improving health outcomes. This review aims to rigorously examine the effectiveness of health literacy interventions targeting Aboriginal and Torres Strait Islander peoples. Methods A systematic review across six databases (The Cochrane Library, PubMed, Embase, SCOPUS, ProQuest Dissertation and Thesis and Web of Science) was performed for publications evaluating interventions to improve health literacy among Indigenous Australian adults using search terms identifying a range of related outcomes. Results Of 824 articles retrieved, a total of five studies met the eligibility criteria and were included in this review. The included studies evaluated the implementation of workshops, structured exercise classes and the provision of discounted fruit and vegetables to improve nutrition, modify risk factors for chronic diseases, and improve oral health literacy. All interventions reported statistically significant improvement in at least one measured outcome. However, there was limited involvement of the Aboriginal and Torres Strait Islander community members in the research process and participant retention rates were sub-optimal. Conclusion There is limited evidence on interventions to improve health literacy in Indigenous Australian adults. Participation in interventions was often suboptimal and loss to follow-up was high. Future studies co-designed with Aboriginal and Torres Strait Islander community members are needed to improve health literacy in this population.

The Impact

Background Immigrants in the United States (US) today are facing a dynamic policy landscape. The Trump administration has threatened or curtailed access to basic services for 10.5 million undocumented immigrants currently in the US. We sought to examine the historical effects that punitive laws have had on health outcomes in US immigrant communities. Methods In this systematic review, we searched the following databases from inception–May 2020 for original research articles with no language restrictions: Ovid MEDLINE, Ovid EMBASE, Cochrane Library (Wiley), Web of Science Core Collection (Clarivate), CINAHL (EBSCO), and Social Work Abstracts (Ovid). This study is registered with PROSPERO, CRD42019138817. Articles with cohort sizes >10 that directly evaluated the health-related effects of a punitive immigrant law or policy within the US were included. Findings 6,357 studies were screened for eligibility. Of these, 32 studies were selected for inclusion and qualitatively synthesized based upon four themes that appeared throughout our analysis: (1) impact on healthcare utilization, (2) impact on women’s and children’s health, (3) impact on mental health services, and (4) impact on public health. The impact of each law, policy, mandate, and directive since 1990 is briefly discussed, as are the limitations and risk of bias of each study. Interpretation Many punitive immigrant policies have decreased immigrant access to and utilization of basic healthcare services, while instilling fear, confusion, and anxiety in these communities. The federal government should preserve and expand access for undocumented individuals without threat of deportation to improve health outcomes for US citizens and noncitizens.

Pediatric Cancer Patients

BackgroundPediatric cancer patients are at high risk for life-threatening infections, therapy associated complications and cancer-related side effects. Exercise is a promising tool to support the immune system and reduce inflammation. The primary objective of this systematic review was to evaluate the effects of exercise interventions in pediatric cancer patients and survivors on the immune system.MethodsFor this systematic review (PROSPERO ID: CRD42021194282) we searched four databases (MEDLINE, Cochrane Library, ClinicalTrials.gov, SPORTDiscus) in June 2021. Studies with pediatric patients with oncological disease were included as main criterion. Two authors independently performed data extraction, risk of bias assessment, descriptive analysis and a direction ratio was calculated for all immune cell parameters.FindingsOf the 1448 detected articles, eight studies with overall n = 400 children and adolescents with cancer and n = 17 healthy children as controls aged 4-19 years met the inclusion criteria. Three randomized, four non-randomized controlled trials and one case series were analyzed descriptively. The exercise interventions had no negative adverse effects on the immune system. Statistically significant results indicated enhanced cytotoxicity through exercise, while changes in immune cell numbers did not differ significantly. Interventions further reduced days of in-hospitalization and reduced the risk of infections. Several beneficial direction ratios in immune parameters were identified favoring the intervention group.InterpretationExercise interventions for pediatric cancer patients and survivors had no negative but promising beneficial effects on the immune system, especially regarding cytotoxicity, but data is very limited. Further research should be conducted on the immunological effects of different training modalities and intensities, during various treatment phases, and for different pediatric cancer types. The direction ratio parameters given here may provide useful guidance for future clinical trials.Systemic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021194282, Prospero ID: CRD42021194282.

The Impact

Abstract Background Intimate partner violence (IPV) is a population health problem linked to a myriad of negative psychological, physical, emotional, sexual and reproductive health outcomes for women. The movement towards working with boys and men over the past couple of decades has increased the number of interventions specifically directed at men who perpetrate violence against a female partner. There is little evidence-based research on key characteristics of effective interventions directed at men to reduce or prevent IPV against female partners. The objective of this systematic review is to identify interventions specifically directed at males , as the perpetrators of violence against women, that have proven to be effective in preventing or reducing intimate partner violence. Methods The following electronic databases will be used to search for peer-reviewed studies: MEDLINE (OVID), Embase (OVID), PsycInfo (OVID), CINAHL (EBSCO), Global Health (EBSCO), Gender Watch (ProQuest), Web of Science (Web of Knowledge), PROSPERO, Cochrane Central Register of Controlled Trials Database (Ovid) and SCOPUS. We will include randomized control trials, non-randomized studies of interventions published in peer-reviewed journals and relevant unpublished manuscripts, books/chapters and clinical or programme study reports. Studies have to demonstrate direction of effect (i.e. pre-post intervention/difference between groups) in terms of prevention or reduction in the outlined outcomes. Primary outcomes include change in behaviour and knowledge of male perpetrator regarding the impact of IPV on women as well as women’s experience of IPV. Secondary outcomes include change in behaviours around substance use and social activities, decrease in negative mental health outcomes and interactions with law enforcement. Studies will be screened, appraised and extracted by two reviewers; any conflicts will be resolved through discussion. Narrative synthesis will be used to analyse and present findings. If sufficient and comparable data is available, a meta-analysis will be conducted. Discussion This review will provide synthesized evidence on interventions directed at males to reduce or prevent their perpetration of intimate partner violence against female partners. Implications for practice will include key characteristics of interventions proven to be effective based on evidence synthesis and certainty of findings. Recommendations for further research will also be considered. Systematic review registration This protocol was submitted for registration in the International Prospective Register of Systematic Reviews (PROSPERO) on September 4, 2020.

The Impact

Objectives: Cardiac surgery using cardiopulmonary bypass frequently provokes a systemic inflammatory response syndrome. This can lead to the development of low cardiac output syndrome (LCOS). Both of these can affect morbidity and mortality. This study is a systematic review of the impact of gaseous nitric oxide (gNO), delivered via the cardiopulmonary bypass (CPB) circuit during cardiac surgery, on post-operative outcomes. It aims to summarise the evidence available, to assess the effectiveness of gNO via the CPB circuit on outcomes, and highlight areas of further research needed to develop this hypothesis. Methods: A comprehensive search of Pubmed, Embase, Web of Science and the Cochrane Library was performed in May 2020. Only randomised control trials (RCTs) were considered. Results: Three studies were identified with a total of 274 patients. There was variation in the outcomes measures used across the studies. These studies demonstrate there is evidence that this intervention may contribute towards cardioprotection. Significant reductions in cardiac troponin I (cTnI) levels and lower vasoactive inotrope scores were seen in intervention groups. A high degree of heterogeneity between the studies exists. Meta-analysis of the duration of mechanical ventilation, length of ICU stay and length of hospital stay showed no significant differences. Conclusion: This systematic review explored the findings of three pilot RCTs. Overall the hypothesis that NO delivered via the CPB circuit can provide cardioprotection has been supported by this study. There remains a significant gap in the evidence, further high-quality research is required in both the adult and paediatric populations.
