Search, screen, and selection of SCD in pregnancy CPGs
We used literature searches of bibliographic databases (Medline/PubMed
and Google Scholar), EBSCO DynaMed Plus (USA), and relevant CPG
databases: the ECRI Institute Guidelines Trust, National Institute of
Health and Care Excellence (NICE; UK), Guidelines International Network
(G-I-N) International guideline library, Scottish Intercollegiate
Guidelines Network (SIGN; UK), and the Australian National Health and
Medical Research Council (NHMRC; Australia). Moreover, we searched
databases of national and international societies specializing in fields
related to our health topic of SCD in pregnancy like the American
College of Obstetricians and Gynecologists (ACOG), Royal College of
Obstetricians and Gynaecologists (RCOG), Royal Australian and New
Zealand College of Obstetricians and Gynaecologists (RANZCOG), Society
for Maternal Fetal Medicine (SMFM), Saudi Society for Obstetrics and
Gynecology (SSOG), and Arab Association of Obstetrics and Gynaecology
Societies (FAGOS). Keywords used included “sickle cell disease” AND
“pregnancy” OR “pregnant women” AND “guideline,” “practice
guideline,” “clinical practice guideline,” “practice parameter,”
“guidance,” OR “recommendations”.11
The PubMed electronic search strategy included; (”anemia, sickle
cell”[MeSH Terms] OR (”anemia”[All Fields] AND ”sickle”[All
Fields] AND ”cell”[All Fields]) OR ”sickle cell anemia”[All
Fields] OR (”sickle”[All Fields] AND ”cell”[All Fields] AND
”disease”[All Fields]) OR ”sickle cell disease”[All Fields]) AND
”pregnan”[All Fields] AND (”pregnancy”[MeSH Terms] OR
”pregnancy”[All Fields]) OR (”pregnant women”[MeSH Terms] OR
(”pregnant”[All Fields] AND ”women”[All Fields]) OR ”pregnant
women”[All Fields]) AND (”guideline”[Publication Type] OR
”guidelines as topic”[MeSH Terms] OR ”guidelines”[All Fields])
AND (Practice Guideline[ptyp] AND (”2014/01/01”[PDAT] :
”2019/12/31”[PDAT]) AND ”humans”[MeSH Terms]). Furthermore, we
used the PIPOH (Patient Population, Interventions, Professionals,
Outcomes, and Healthcare Setting) model to support the CPG eligibility
process.10 Three reviewers (YA, MA, YS) screened
titles and abstracts of retrieved CPGs and articles meeting the
inclusion criteria independently. The screening was re-checked by three
different reviewers (GE, AA, OK). Disagreements were resolved by focus
group discussions within the whole group after retrieval and review of
the full-text articles or full CPG documents, including links to any
accessible online supplementary documents or web resources. The search
was repeated before the final manuscript submission to retrieve any new
eligible CPG.
