Interventions to reduce emergency department utilisation: A review of reviews ☆

Studies measuring the completeness and consistency of trial registration and reporting rely on linking registries with bibliographic databases. In this systematic review, we quantified the processes used to identify these links. PubMed and Embase databases were searched from inception to May 2016 for studies linking trial registries with bibliographic databases. The processes used to establish these links were categorised as automatic when the registration identifier was available in the bibliographic database or publication, or manual when linkage required inference or contacting of trial investigators. The number of links identified by each process was extracted where available. Linear regression was used to determine whether the proportions of links available via automatic processes had increased over time. In 43 studies that examined cohorts of registry entries, 24 used automatic and manual processes to find articles; 3 only automatic; and 11 only manual (5 did not specify). Twelve studies reported results for both manual and automatic processes and showed that a median of 23% (range from 13 to 42%) included automatic links to articles, while 17% (range from 5 to 42%) of registry entries required manual processes to find articles. There was no evidence that the proportion of registry entries with automatic links had increased (R
 2 = 0.02, p = 0.36). In 39 studies that examined cohorts of articles, 21 used automatic and manual processes; 9 only automatic; and 2 only manual (7 did not specify). Sixteen studies reported numbers for automatic and manual processes and indicated that a median of 49% (range from 8 to 97%) of articles had automatic links to registry entries, and 10% (range from 0 to 28%) required manual processes to find registry entries. There was no evidence that the proportion of articles with automatic links to registry entries had increased (R
 2 = 0.01, p = 0.73). The linkage of trial registries to their corresponding publications continues to require extensive manual processes. We did not find that the use of automatic linkage has increased over time. Further investigation is needed to inform approaches that will ensure publications are properly linked to trial registrations, thus enabling efficient monitoring of trial reporting.

A systematic review of the processes used to link clinical trial registrations to their published results

The requirement for literature searches that identify studies for inclusion in systematic reviews should be systematic, explicit, and reproducible extends, at least by implication, to other types of literature review. However, realist reviews commonly require literature searches that challenge systematic reporting; searches are iterative and involve multiple search strategies and approaches. Notwithstanding these challenges, reporting of the "realist search" can be structured to be transparent and to facilitate identification of innovative retrieval practices. Our six-component search framework consolidates and extends the structure advanced by Pawson, one of the originators of realist review: formulating the question, conducting the background search, searching for program theory, searching for empirical studies, searching to refine program theory and identifying relevant mid-range theory, and documenting and reporting the search process. This study reviews reports of search methods in 34 realist reviews published within the calendar year of 2016. Data from all eligible reviews were extracted from the search framework. Realist search reports poorly differentiate between the different search components. Review teams often conduct a single "big bang" multipurpose search to fulfill multiple functions within the review. However, it is acknowledged that realist searches are likely to be iterative and responsive to emergent data. Overall, the search for empirical studies appears most comprehensive in conduct and reporting detail. In contrast, searches to identify and refine program theory are poorly conducted, if at all, and poorly reported. Use of this framework offers greater transparency in conduct and reporting while preserving flexibility and methodological innovation.

The "realist search": A systematic scoping review of current practice and reporting.

Telephone nursing services are expanding globally. Swedish Healthcare Direct is the largest healthcare provider in Sweden. This paper provides a comprehensive understanding of telephone nursing, as reflected by research on Swedish national telephone nursing, and discusses the findings in relation to international literature. A descriptive, mixed-studies literature review was conducted. Twenty-four articles from January 2003 to April 2015 were identified from PubMed, Scopus, and CINAHL, and included. The issues explored in this study are how telephone nursing is perceived by callers, telephone nurses, and managers, and what characterizes such calls. Callers value reassurance, support, respect and satisfaction and involvement in decisions can increase their adherence. The telephone nurses' perspective focused on problems and ethical dilemmas, communication, the decision support tool, and working tasks. The managers' perspective focused on nursing work goals and malpractice claims. Concerning call characteristics, authentic calls, incident reports, and threats to patient safety were considered. Telephone nursing seems safe, but gender can play a role in calls. Future research on caller access, equity, and efficiency, healthcare cost-effectiveness, distribution, and patient safety is needed.

Objective The purpose of this review was to systematically evaluate the effects of an alcohol vehicle solution (V-Sol) compared with an essential-oils mouthwash (EOMW) and if available with a water-based control (WC) on plaque, gingival inflammation parameters and extrinsic tooth staining. Materials and Methods The PubMed-MEDLINE, Cochrane-CENTRAL and EMBASE databases were searched. Where appropriate, a meta-analysis was performed, and difference of means (DIFFM) as calculated. Results In total, 971 unique papers were found of which five met the eligibility criteria. The DIFFM of the meta-analysis of four 6-month studies showed that the EOMW provided significantly better plaque control (DIFFM = 0.39, P < 0.00001) and gingival inflammation reduction as measured by the Loe and Silness Index (DIFFM = 0.36, P = 0.00001) as compared to the V-Sol. Regarding extrinsic tooth staining, a small but significant difference (DIFFM = −0.08, P = 0.03) was observed. Conclusion Limited data, but with a low risk of bias, were available to assess the potential benefit of the alcohol-containing V-Sol. ‘High’- and ‘moderate’-quality data were available for the analysis of plaque and gingivitis, respectively. Within these limitations, EOMW appears to provide a significant oral health benefit during the 6 months of use. The data retrieved for this review suggest that the essential oils produce an effect on plaque and gingivitis that extends beyond the V-Sol. Furthermore, the V-Sol proved to be no different from a WC.

Patient safety is a persistent problem in telephone triage research; however, studies have not differentiated between clinicians' and non-clinicians' respective safety. Currently, four groups of decision makers perform aspects of telephone triage: clinicians (physicians, nurses), and non-clinicians (emergency medical dispatchers (EMD) and clerical staff). Using studies published between 2002-2012, we applied Donabedian's structure-process-outcome model to examine groups' systems for evidence of system completeness (a minimum measure of structure and quality). We defined system completeness as the presence of a decision maker and four additional components: guidelines, documentation, training, and standards. Defining safety as appropriate referrals (AR) - (right time, right place with the right person), we measured each groups' corresponding AR rate percentages (outcomes). We analyzed each group's respective decision-making process as a safe match to the telephone triage task, based on each group's system structure completeness, process and AR rates (outcome). Studies uniformly noted system component presence: nurses (2-4), physicians (1), EMDs (2), clerical staff (1). Nurses had the highest average appropriate referral (AR) rates (91%), physicians' AR (82% average). Clerical staff had no system and did not perform telephone triage by standard definitions; EMDs may represent the use of the wrong system. Telephone triage appears least safe after hours when decision makers with the least complete systems (physicians, clerical staff) typically manage calls. At minimum, telephone triage decision makers should be clinicians; however, clinicians' safety calls for improvement. With improved training, standards and CDSS quality, the 24/7 clinical call center has potential to represent the national standard.

Safety of Clinical and Non-Clinical Decision Makers in Telephone Triage: A Narrative Review:

Background: Authors of systematic reviews have difficulty obtaining unpublished data for their reviews. This project aimed to provide an in-depth description of the experiences of authors in searching for and gaining access to unpublished data for their systematic reviews, and to give guidance on best practices for identifying, obtaining and using unpublished data. Methods: This is a qualitative study analyzing in-depth interviews with authors of systematic reviews who have published Cochrane reviews or published systematic reviews outside of The Cochrane Library. We included participants who 1) were the first or senior author of a published systematic review of a drug intervention, 2) had expertise in conducting systematic reviews, searching for data, and assessing methodological biases, and 3) were able to participate in an interview in English. We used non-random sampling techniques to identify potential participants. Eighteen Cochrane authors were contacted and 16 agreed to be interviewed (89% response rate). Twenty-four non-Cochrane authors were contacted and 16 were interviewed (67% response rate). Results: Respondents had different understandings of what was meant by unpublished data, including specific outcomes and methodological details. Contacting study authors was the most common method used to obtain unpublished data and the value of regulatory agencies as a data source was underappreciated. Using the data obtained was time consuming and labor intensive. Respondents described the collaboration with other colleagues and/or students required to organize, manage and use the data in their reviews, generally developing and using templates, spreadsheets and computer programs for data extraction and analysis. Respondents had a shared belief that data should be accessible but some had concerns about sharing their own data. Respondents believed that obtaining unpublished data for reviews has important public health implications. There was widespread support for government intervention to ensure open access to trial data. Conclusions: Respondents uniformly agreed that the benefit of identifying unpublished data was worth the effort and was necessary to identify the true harms and benefits of drugs. Recent actions by government, such as increased availability of trial data from the European Medicines Agency, may make it easier to acquire critical drug trial data.

Strategies for obtaining unpublished drug trial data: a qualitative interview study

Objectives. We documented barriers to workers' compensation and injury-related medical care faced by homecare or Personal Assistance Services (PAS) workers. We explored differences between independent providers and agency-employed workers. Methods. We conducted in-depth, semi-structured interviews with a diverse sample of 38 injured workers. Participants were primarily female and racial-ethnic minorities. Results. Most participants (82%) were independent providers. Common barriers to reporting injury included commitments to clients and financial pressure. Unlike agency employees, many independent providers knew little about workers' compensation eligibility and injury reporting procedures, and frequently were given “the runaround” by the social service bureaucracy when they attempted to report injury and access injury-related medical care. Among independent providers, delays in filing a claim and receiving timely medical attention were common. Conclusions. The lack of a traditional employment inf...

Exposure to pollution is a significant risk to human health. However few studies have attempted to identify the types of policy interventions that can reduce the health risks of pollution exposure in the United States. The study objective was to conduct a realist review of policy interventions conducted or aimed at reducing chemical exposures in humans or the environment where exposure was measured. A systematic literature search identified published articles that assessed policy interventions using exposure data. Two coders independently extracted data from the studies, assessing methods, context, details of interventions, outcomes, and risks of bias. Data were analyzed iteratively and manually to identify the most effective and transferrable types of interventions. The reasons for variability in the success of different interventions were explored. The review found that regulatory interventions that eliminate point sources of pollution appeared to reduce exposure to environmental hazards. Regular monitoring to provide environmental and human exposure data helped assess compliance with the regulatory standards. Educational and economic interventions were less successful. Although some types of regulatory interventions appear to reduce exposures, our findings are limited by the nature of existing interventions, the weaknesses of the study designs used in the literature, and the lack of details on implementation. Information on contextual factors that influence implementation would assist with future reviews and could help identify effective interventions.

Author(s): Wolfe, Nicole Elizabeth | Advisor(s): Harrington, Charlene | Abstract: In 2006, Gardasil, the first human papillomavirus (HPV) vaccine was approved by the Food and Drug Administration to protect women age 9-26 against four strains of HPV, 16, 18, 6, and 11 that cause 70 percent of cervical cancer cases and 90 percent of genital warts cases respectively. The objective of this dissertation was to understand the process of the development, approval, and marketing of the Gardasil vaccine. This project used a qualitative, exploratory, single case study research method using data collected from articles, press releases, government, and industry documents, as well as interviews from key informants in 2008 and 2009. After the technology was acquired by Merck in 1995, the clinical trials were conducted from 1997 to 2005, and Gardasil was approved with five years of data to support claims of safety and efficacy. Promotional campaigns began in 2005 prior to Gardasil's release through awareness efforts that linked HPV and cervical cancer. The primary marketing campaign for Gardasil began after its approval and release to encourage females to visit their physicians to discuss vaccination and to encourage physicians to give the vaccine. The campaign has been a success, resulting in about 25 percent of eligible females receiving the vaccine and making Gardasil a profitable venture. Gardasil is sold at high prices largely in the United States where cervical cancer has been largely mitigated by pap smears and preventive health care. Merck facilitated the social construction of the human papillomavirus as a problem needing treatment and successfully positioned Gardasil to be the solution to that problem.
