Development of the Rehabilitation Health Policy, Systems, and Services Research Field: Quantitative Analyses of Publications over Time (1990–2017) and across Country Type
Abstract
:1. Introduction
- What is the total amount, absolute growth, and relative growth of Rehabilitation HPSSR publications (i.e., as the percentage of all rehabilitation research publications, and as the percentage of all HPSSR publications)?
- Which portion of the Rehabilitation HPSSR has been published in rehabilitation journals, and has that changed over time?
- Which portion of the country-specific rehabilitation HPSSR publications focus on high-income countries (HICs) versus low- and middle-income countries (LMICs)?
- What are the yearly rates of the Rehabilitation HPSSR publications that declare funding support, and how does that compare to rehabilitation research overall and HPSSR overall.

Appendix A. Search Strategy
- In this Appendix, we present the complete search filters that were used. They enable the reproduction of the searches in PubMed (https://0-www-ncbi-nlm-nih-gov.brum.beds.ac.uk/pubmed). Of note, as the indexation process in PubMed is an ongoing endeavor; hence, values retrieved can be slightly higher than those presented in the results, especially for the number of articles published in the more recent years.
- Whenever reproducing the target searches, one needs to combine the relevant search filters below, using the Bolean operator “AND” in between.
- ○
- For example, in the search aimed at locating rehabilitation HPSSR, the following combination of search filters must be employed: the Common Filter (used into all searches) AND the HPSSR filter AND the Rehabilitation Filter.
- Search filters were based essentially on MeSH terms. All lower-level MeSH Terms, i.e., all under those actually written, are included by default, unless otherwise specified (i.e., with the use of the operator “NOT”).
- The hierarchical tree of MeSH terms, their definitions, and which MeSH terms are included under each MeSH term can be consulted at: https://0-www-ncbi-nlm-nih-gov.brum.beds.ac.uk/mesh.
Note: Even though not written down, relevant MeSH terms such as but not limited to “Health Services Needs and Demand”[Majr] OR “Health Workforce”[Majr] OR “Health Services Accessibility”[Majr] OR “Health Equity” [Majr] are included into the search filter (i.e., fully contained within upper-level MeSH terms included, such as but not limited to “Health Administration”[Majr]). In practice, adding any of the terms exemplified above to the search filter do not change the total number of articles retrieved.
Note: Even though not written down, relevant MeSH terms such as but not limited to “Neurological Rehabilitation”[Majr] and “Cardiac Rehabilitation”[Majr] are included into the search filter (i.e., fully contained within upper-level MeSH terms included, such as “Rehabilitation”[Majr]). In practice, adding any of the illustrated MeSH terms to the search filter above do not change the total number of articles retrieved.
Note: This filter contains all the forms of funding support.
