They excluded 115 potential concepts for the following reasons: inadequate conceptualisation (31 concepts in 17 studies 11,150,155,160,162,169,173,178,181,188,192,196,197,206,208,219 ); did not explore HCP experience (18 concepts in seven studies 168,174,198,202,203,215,223 ); and explored a topic with limited transferability beyond a specific context (five concepts in five studies 166,167,197,208,223 ). We agreed that for some topics there were insufficient concepts to allow us to develop robust conceptual categories: return to work (seven concepts in two studies 167,182 ), ethnicity (11 concepts in five studies 171,204,205,215,216 ), gender (seven concepts in one study 206 ) and older people (21 concepts in nine studies 159,160,162,165,176,187,194,199,…”
