Common Problems

Today, the world of research is quite literally available through the touch of a few buttons via online resaerch. But this increase in access and availability is not without its challenges. With ‘hits’ that can run into millions, unless the student knows how to search effectively and efficiently, the information that he or she finds can quickly become overwhelming. This chapter guides students through the process of literature searching for their dissertation. It outlines how to develop a successful search strategy and what to do with the literature once it is discovered. Topics covered include what counts as literature; different ‘types’ of literature searching; how to develop a literature search strategy; and common problems associated with literature searching.

Using heparinised saline as a flush to maintain the patency of arterial and central venous lines is a well-known practice. A literature search was undertaken but found no evidence to support the use of heparinised saline over normal saline. In addition, the use of heparinised saline may be associated with adverse effects. The literature search strategy utilised Ovid CINAHL and Medline databases, as well as hand-searching bibliographies of clinical and research articles from the University of Cambridge Medical Library. Keywords and phrases included ‘heparin’, ‘normal saline’, ‘arterial’, ‘haemodynamic lines’ and ‘catheters’. All types of evidence from each of these resources were examined to identify major themes, areas of agreement and disagreement across clinical practice, changes in the concept over time and emerging trends.

The scope of this study was to conduct a systematic review of the studies on the association between obesity and periodontitis. The methods applied included a literature search strategy and selection of studies using inclusion and exclusion in accordance with the criteria for characteristics of the studies and meta-analysis. The research was conducted in the PubMed, Embase and Lilacs databases through 2010. Selected papers were on studies on humans investigating whether or not obesity is a risk factor for periodontitis. Of the 822 studies identified, 31 studies met the inclusion criteria and were included in this meta-analysis. The risk of periodontitis was associated with obesity (or had a tendency for this) in 25 studies, though it was not associated in 6 studies. The meta-analysis showed a significant association with obesity and periodontitis (OR = 1.30 [95% Confidence Interval (CI), 1.25 - 1.35]) and with mean Body Mass Index (BMI) and periodontal disease (mean difference = 2.75). Obesity was associated with periodontitis, however the risk factors that aggravate these diseases should be better clarified to elucidate the direction of this association. Working with paired samples and avoiding confusion factors may contribute to homogeneity between the studies.

Literature Search Strategy

The management of chronic diseases (CD) includes physical activity (PA). It is necessary to determine the effects of COVID-19 restrictions in CD. The aim was to review the research related to PA levels before and during the COVID-19 pandemic in people with CD. This review was designed according to PRISMA guidelines and registered in PROSPERO: CRD42020218825. The search was performed in CINAHL, Medline, Scopus, and Web of Science up to January 2021. The PICOS recommendations were applied. The search was conducted by two reviewers, who completed the data extraction of included articles. Methodological quality was assessed using the STROBE checklist, and a meta-analysis was conducted. The literature search strategy identified 227 articles. Five studies remained and were included. Only three studies were included in the meta-analysis. Two articles used accelerometers to objectively compare PA levels before and during the pandemic. Three studies made this comparison using an online survey. All articles showed a decrease in PA levels during the COVID-19 pandemic. The meta-analysis showed a significant reduction in PA levels during pandemic. PA levels during the COVID-19 pandemic have been reduced with respect to previous levels of PA in patients with CD.

Literature search strategy for Health Technology Assessment Reports Preparation of HTA reports requires access to the latest and most reliable knowledge in the field of health care. Systematic reviews are the basic tools used to obtain it. In order to find the literature necessary for a systematic review, search strategies are performed in databases. With their help it is possible to thoroughly and reliably search the resources of individual databases and find the required information. Properly executed search strategies also reduce the risk of missing valuable publications. During the preparation of the search strategy, one should use the tools and additional functions implemented in individual databases, thanks to which it is possible to strictly control the process and adapt it to your own needs. Performing a search strategy is a basic skill for anyone who prepares HTA reports.
