The original search yielded 970 articles. A total of 141 duplicates were removed. In the initial title and abstract screening step, 829 articles were examined. A further 801 articles were removed upon applying exclusion criteria. The exclusion criteria were: unrelated to SDH (n = 229), associated with undergraduate curricula (n = 129), not curriculum-based (n = 97), irrelevant (n = 71), nursing curricula (n = 62), related to public health and disease prevention (n = 57), allied health curricula (n = 50), considered with global health and elimination of global issues (n = 25), internship (n = 20), unstructured programs (n = 20), social accountability (n = 13), pharmacy curricula (n = 11), dentistry curricula (n = 9) and book chapter (n = 8).
Only 28 articles met the inclusion criteria. The next step was a full examination of the 28 articles that met the inclusion criteria and whose focus was oriented towards the contents of the SDH in graduate medical education. At this point, we removed seven articles as they did not meet the quality assessment criteria.
A total of 21 articles met the inclusion criteria and were included in the review. A hand search through the references of the included articles yielded another four studies; three were deemed eligible for inclusion, and one pilot program was excluded. The final number of articles included in the review was 24.

Summary of the graduate SDH training programs
Of the twenty-four programs included in the current scoping review, twenty-two were from graduate residency programs in the United States of America, one program was from Canada and one program was from a residency program in Kenya. 50% (n = 12) of the articles were based in paediatric graduate curricula, while almost 21% (n = 5) were from internal medicine programs, as indicated in Table 2.

Structure and duration of the postgraduate SDH training
As explained in table 3, the duration of the program relating to SDH varied. A total of twelve programs had longitudinal modules, which spanned between one to three years of the postgraduate medical residency [22–33], while five other programs spanned between two to nine months of postgraduate medical residency [34–38]. Seven programs took between two weeks and six weeks [39–43, 43, 44], while the shortest program involved three online simulations, each simulation is 4 hours (one-half day) and completed during a module on advocacy .[45]

The structure of the programs related to SDH varied across a range of thematic areas. A total of five courses had a focus on home visits and different community healthcare interventions [23, 30, 31, 40, 41], while another set of ten programs were in the form of case-based workshops on a variety of topics such as prison healthcare, housing issues locating pharmacies and follow-up of patients after discharge [24–26, 28, 29, 32, 34, 39, 43, 45] Lastly, nine programs focused on health advocacy topics, such as opportunities to integrate SDH at community health clinics, housing, education and legal issues, integration of health disparities to clinical practices and equity, diversity, and inclusion [22, 27, 33–38, 44].
Programs presentation methods
The approach to presenting the graduate SDH training and learning activities varied. All the programs used participatory learning," where the learners are actively participating instead of being passive listeners," as an educational strategy in combination with other teaching modalities. Eleven programs combined participatory learning with community placement and didactic teaching [23–25, 28, 31, 33, 34, 36, 40–42]. Another six programs relied on a participatory approach, with community placement and no formal lectures[27, 35, 36, 43–45]. Three programs integrated didactic teaching and a participatory approach with no community engagement [29, 37, 38]. Another set of four programs included participatory learning only, requiring participant engagement, such as information gathering, group discussions, and activities [22, 26, 32, 39].
Evaluation of the graduate SDH programs
All the reviewed programs (n = 24) had an evaluation component in their curriculum. Eight programs used pre- and post-learning evaluation surveys [24, 25, 29, 30, 32, 35, 38, 43], while eleven programs used only post-learning evaluation surveys [22, 27, 28, 31, 36, 37, 39–41, 44, 45]. Two programs used thematic analysis of participants’ written reflections and interviews [26, 34]. One program used both survey and reflection through the course of the program.[23]. Only one program evaluated the participant's and the patient's primary guardians' views [33].
Four programs evaluated the participants’ affective learning, including their attitude of awareness, interest, and empathy combined with their level of knowledge regarding the SDH within the local context [29, 31, 42, 44]. Another three programs used affective learning assessment solely [33, 35, 41]. One program adopted comprehensive assessment on the three levels, including participants’ attitudes, knowledge and performance [43]. Another program incorporated knowledge and performance as an evaluation tool [38], and one used the candidate's performance as the main evaluation aspect [34]. An additional twelve programs only used the participants’ knowledge level as an evaluation indictor [24–28, 30, 32, 37, 39–41, 45].
