MEDLINE (Ovid), EMBASE (Ovid), AMED (Ovid), PsycINFO (Ovid), Cochrane Central (Ovid), CINAHL (EBSCO) and Web of Science (Thomson Reuters, excluding patents) were searched up to November 2016. As per Barnish and Barnish [21 (link)], we applied the following keywords to all databases: “positive heel inclination”, “high heel”, “high-heeled”, ‘“high heeled”, “wedge heel”, “platform heel”, “platform shoe”, “stiletto” and “elevator shoe”. The only change we made was to add quotation marks to increase search specificity. Supplementary searches were conducted in Google Scholar (GS), Directory of Open Access Journals (DOAJ) and bibliographies of relevant articles.

The following bibliographic databases, enabling literature indexing and providing access to abstracts will be consulted: Medline (Ovid), Embase (Embase.com">Embase.com), CINAHL (EBSCO), ÉRUDIT, CAIRN, PsycINFO (Ovid), Sociological Abstracts (Proquest), Web of Science.

In PubMed, Web of Science (Thomson Reuters), and PsycINFO (EBSCO), we identified studies using search terms for burnout and sub-Saharan African countries (Additional file 1: Table S2). Search terms included all sub-Saharan African countries. All articles published prior to February 14, 2019 were eligible for inclusion. We only included articles available in English. Based on the title and abstract review of all articles, we rejected any articles that were not relevant or did not meet the study criteria. Studies were selected for inclusion if (1) they examined a quantitative measure of burnout, (2) the study population was healthcare providers, and (3) the study was conducted in a sub-Saharan African country. Healthcare providers included physicians, nurses, medical or nursing students, midwives, and other hospital workers. Studies were excluded for (1) not including a quantitative measure of burnout, (2) not measured in healthcare providers, or (3) not conducted in sub-Saharan Africa.
Full texts of articles examining populations of healthcare providers were reviewed. Reference sections of included articles were also reviewed for additional relevant studies. A companion article examines burnout among healthcare providers in the Middle East and Northern Africa (Chemali et al, under review).

The relevant literature was identified by using the results of a systematic literature review from 2014 of the same authors [1 (PubMed.ncbi.nlm.nih.gov/24383435/">link)] and by performing new searches in the electronic bibliographic databases Business Source Ultimate (via Ebsco), Cinahl Plus with full text (via Ebsco), Embase (via Ovid), ERIC (via Ebsco), PsycInfo (via Ebsco), PubMed and Web of Science (Core Collection). The 2014 review considered literature from 1995 (the year in which the ADA was published) to 2013. For this review, only the qualitative studies from the 2014 review were used and they were subjected to the same procedure as the newer studies. The new systematic searches in the databases included studies published from 2013 (because that year was just partly covered in the 2014 review) untill January 2021 (the date limit for the search). The searches were focused on dyslexia, employment and qualitative research.

Qualitative and quantitative searches were performed independently in June 2019 using the following databases: MEDLINE (Ovid), EMBASE (Ovid), Web of Science, CINAHL (EBSCOhost), PsycINFO (Ovid), and British Nursing Index (ProQuest). Additionally, ASSIA and Sociological Abstracts (via ProQuest) were also searched for qualitative studies, and the Cochrane Central Register of Controlled Trials (CENTRAL) database was searched for quantitative studies. Reference lists were hand-searched and forward citation tracking of included studies was completed. Searches commenced for studies published from 1995, when the increasing importance of guidelines and advances in technology led to the widespread adoption of computerised medical records,¹⁴ which facilitated the use of templates and the secondary use of data.¹⁴ Prior to submission for publication (July 2020), forward citation tracking was carried out on all included studies, which is recognised as an efficient approach to updating reviews.^{15 (link)}

The following databases were systematically searched between February 28 and March 15, 2021, using defined keywords (and synonyms) like “mental workload,” “health information system,” “assessment,” “health care professionals,” and “eye tracking” that resulted in specified search strings: MEDLINE (PubMed), Web of Science, Academic Search Premier and CINAHL (both EBSCO), and PsycINFO. Additionally, we will search for relevant research in the reference sections of included studies as well as those of relevant recently published reviews. Following PRISMA-P [28 (link)], we organized the search terms by database and question in a separate document (Multimedia Appendix 1).
