Cumulative Index to Nursing and Allied Health Literature search strategies for identifying methodologically sound causation and prognosis studies

Context Video games represent a multibillion-dollar industry in the U.S. Although video gaming has been associated with many negative health consequences, it may also be useful for therapeutic purposes. The goal of this study was to determine whether video games may be useful in improving health outcomes. Evidence acquisition Literature searches were performed in February 2010 in six databases: the Center on Media and Child Health Database of Research, MEDLINE, CINAHL, PsycINFO, EMBASE, and the Cochrane Central Register of Controlled Trials. Reference lists were hand-searched to identify additional studies. Only RCTs that tested the effect of video games on a positive, clinically relevant health consequence were included. Study selection criteria were strictly defined and applied by two researchers working independently. Study background information (e.g., location, funding source), sample data (e.g., number of study participants, demographics), intervention and control details, outcomes data, and quality measures were abstracted independently by two researchers. Evidence synthesis Of 1452 articles retrieved using the current search strategy, 38 met all criteria for inclusion. Eligible studies used video games to provide physical therapy, psychological therapy, improved disease self-management, health education, distraction from discomfort, increased physical activity, and skills training for clinicians. Among the 38 studies, a total of 195 health outcomes were examined. Video games improved 69% of psychological therapy outcomes, 59% of physical therapy outcomes, 50% of physical activity outcomes, 46% of clinician skills outcomes, 42% of health education outcomes, 42% of pain distraction outcomes, and 37% of disease self-management outcomes. Study quality was generally poor; for example, two thirds (66%) of studies had follow-up periods of <12 weeks, and only 11% of studies blinded researchers. Conclusions There is potential promise for video games to improve health outcomes, particularly in the areas of psychological therapy and physical therapy. RCTs with appropriate rigor will help build evidence in this emerging area.

The Cochrane Collaboration was established in 1993, following the opening of the UK Cochrane Centre in 1992, at a time when searching for studies for inclusion in systematic reviews was not well-developed. Review authors largely conducted their own searches or depended on medical librarians, who often possessed limited awareness and experience of systematic reviews. Guidance on the conduct and reporting of searches was limited. When work began to identify reports of randomized controlled trials (RCTs) for inclusion in Cochrane Reviews in 1992, there were only approximately 20,000 reports indexed as RCTs in MEDLINE and none indexed as RCTs in Embase. No search filters had been developed with the aim of identifying all RCTs in MEDLINE or other major databases. This presented The Cochrane Collaboration with a considerable challenge in identifying relevant studies.Over time, the number of studies indexed as RCTs in the major databases has grown considerably and the Cochrane Central Register of Controlled Trials (CENTRAL) has become the best single source of published controlled trials, with approximately 700,000 records, including records identified by the Collaboration from Embase and MEDLINE. Search filters for various study types, including systematic reviews and the Cochrane Highly Sensitive Search Strategies for RCTs, have been developed. There have been considerable advances in the evidence base for methodological aspects of information retrieval. The Cochrane Handbook for Systematic Reviews of Interventions now provides detailed guidance on the conduct and reporting of searches. Initiatives across The Cochrane Collaboration to improve the quality inter alia of information retrieval include: the recently introduced Methodological Expectations for Cochrane Intervention Reviews (MECIR) programme, which stipulates 'mandatory’ and 'highly desirable’ standards for various aspects of review conduct and reporting including searching, the development of Standard Training Materials for Cochrane Reviews and work on peer review of electronic search strategies. Almost all Cochrane Review Groups and some Cochrane Centres and Fields now have a Trials Search Co-ordinator responsible for study identification and medical librarians and other information specialists are increasingly experienced in searching for studies for systematic reviews.Prospective registration of clinical trials is increasing and searching trials registers is now mandatory for Cochrane Reviews, where relevant. Portals such as the WHO International Clinical Trials Registry Platform (ICTRP) are likely to become increasingly attractive, given concerns about the number of trials which may not be registered and/or published. The importance of access to information from regulatory and reimbursement agencies is likely to increase. Cross-database searching, gateways or portals and improved access to full-text databases will impact on how searches are conducted and reported, as will services such as Google Scholar, Scopus and Web of Science. Technologies such as te...

“…Using comprehensive search strategies that combined terms for pressure ulcer 9 with published prognosis study search filters, [10][11][12][13] we searched Ovid MEDLINE and EBSCO CINAHL Plus on 14 February 2017 without any restriction. We also searched ProQuest for relevant doctoral theses and screened the reference lists of eight relevant systematic reviews, 8,[14][15][16][17][18][19][20] as well as of potentially eligible studies.…”

Summary Background Empirical evidence is uncertain regarding the value of nonblanchable erythema in predicting the incidence of stage 2 (or more severe) pressure ulcers. Objectives To investigate whether nonblanchable erythema is an independent prognostic factor for pressure ulcer incidence using individual patient data. Methods We performed an electronic database search in February 2017 to identify longitudinal studies that considered nonblanchable erythema for predicting pressure ulcer risk in any population. We collected individual participant data for the included studies, and assessed the risk of bias of these studies using the Quality In Prognosis Studies tool. We analysed individual participant data in Stata using mixed‐effects logistic regression to investigate the association of interest. The certainty of evidence from individual participant data analysis was assessed using the Grades of Recommendation Assessment, Development and Evaluation. The study was registered with PROSPERO (CRD42017081151). Results From the 13 included studies (total 68 077 participants) we had access to individual participant data from four (n = 3223), and 11·9% of participants (383 of 3223) developed new pressure ulcers of stage 2 or above within 28 days. Mixed‐effects logistic regression showed that participants with nonblanchable erythema had higher odds of developing new pressure ulcers of stage 2 or above within 28 days of follow‐up than those without nonblanchable erythema (multivariable association: n = 2684; odds ratio 2·72, 95% confidence interval 2·02–3·69; τ2 = 0; moderate‐certainty evidence). Conclusions This first prognostic factor review with individual‐level data analysis in patients with pressure ulcers suggests that people with nonblanchable erythema are more likely to develop new pressure ulcers of stage 2 or above within 28 days than people without nonblanchable erythema. It is important to identify nonblanchable erythema in practice and to intervene appropriately to prevent pressure ulceration. What's already known about this topic? Pressure ulcer reduction is a high priority for healthcare systems. Regularly inspecting skin to identify skin abnormalities is one key practice for preventing ulceration. Nonblanchable erythema – discoloration of the skin that does not turn white when pressed – is one clinically important skin abnormality. Empirical evidence synthesized using conventional meta‐analysis is uncertain regarding the value of nonblanchable erythema for predicting open pressure ulcer incidence; this is partly because the conventional technique has weakness in terms of pooling prognostic effects of different multivariable analyses across studies. What does this study add? This prognostic factor review used individual‐level data analysis to overcome the limitations of the conventional meta‐analysis technique. For the first time there is confirmatory and moderate‐certainty evidence on the association of nonblanchable erythema with pressure ulcer incidence. People with nonblanchable erythema are m...
