The development of pGALSplus: evaluating feasibility and acceptability of an assessment to facilitate the identification and triage of children with musculoskeletal presentations.

Objectives: Healthcare professionals (HCPs) need to identify potentially serious musculoskeletal (MSK) presentations in children and refer them to specialists appropriately. Our aim was to develop 'pGALSplus' (paediatric gait, arms, legs and spine plus) to support clinical assessment, aid decision-making and assess feasibility and acceptability in exemplar MSK pathologies. Methods: We used a three-phase mixed methods approach: phase 1, preliminary stakeholder engagement and scoping review to propose pGALSplus; phase 2, iterative development of pGALSplus involving an expert working group; and phase 3, testing the feasibility of pGALSplus in exemplar MSK conditions [JIA, mucopolysaccharidoses (MPS), muscular dystrophy (MD), developmental coordination disorder (DCD) and healthy controls (HCs)]. The final pGALSplus was derived from analysis of phase 3 data and feedback from HCPs, families and expert consensus input from an international e-survey (n = 22) and virtual event (n = 13). Results: Feasibility was tested in 45 children (JIA, n = 10; MPS, n = 6; MD, n = 9; DCD, n = 10; HCs, n = 10). Overall the assessment was achievable in the target age range (2-10 years) and quick to complete [median 12 min (range 8-20)], with high acceptability from families. Expert feedback deemed pGALSplus to be very useful and of particular use to non-specialists in MSK paediatrics. The final pGALSplus comprises 26 clinical observations/skills with a colour-coding approach to aid decision-making and identification of more serious MSK presentations and additional resources to support its use in clinical practice. Conclusions: pGALSplus is a novel evidence- and consensus-based assessment building on pGALS, with high acceptability and feasibility. As community-based MSK assessment in children becomes more established, we propose that pGALSplus will facilitate and inform decision-making to promote access to specialist care.

Beyond pGALS: the need for a multifaceted musculoskeletal decision-making tool ('pGALSplus') in community-based clinical practice.

Musculoskeletal (MSK) problems in children are common, and health-care professionals must identify those requiring onward referral. Paediatric gait, arms, legs and spine (pGALS) is an MSK assessment to discern abnormal joints. We aimed to identify MSK assessments to add to pGALS (pGALSplus) to facilitate decision-making in the context of exemplar conditions representing a spectrum of MSK presentations, namely JIA, mucopolysaccharidoses, muscular dystrophy and developmental co-ordination disorder. A literature review identified 35 relevant articles that focused on clinical assessments [including questionnaire(s), physical examination and functional tests] used by health-care professionals in the context of the exemplar conditions. We provide a description of these assessments and the rationale regarding how they, or components of such tools, might be useful within pGALSplus. This process provides a foundation for further work to develop and validate pGALSplus.
