“…Physiotherapists were the most common professional group in these interface services, working independently [17, 18, 22-29, 35, 38, 40], or alongside other professionals [19-21, 30, 34, 37, 41, 43]. Figure 2 illustrates that interface services were community-based [23-26, 30, 39-42] or hospital-based [19-21, 34-37, 43], although the location was not always clear, and three studies used hospital-led telehealth-assisted triage [31,32,38]. Interface services were principally accessed via direct referral from primary care, although in a small number of pathways the referral was first sent to a secondary care consultant service and subsequently triaged to an interface clinic [31,32,34,36,38,41,43] or both direct and indirect referral was available [24][25][26]35].…”
