Abstract
Objectives
The Keele STarT MSK tool is a questionnaire to identify the prognostic factors for musculoskeletal conditions, such as shoulder complaints, developed by Keele University, UK. This study assessed whether the Keele STarT MSK tool can predict the risk of poor outcome in non-specific shoulder complaints in a Dutch population.
Design
Multicentre prospective cohort study.
Setting
Fourteen primary care physiotherapy clinics in the Netherlands participated in this study.
Participants
In total, 180 patients with non-specific shoulder complaints with complete data from the Keele STarT MSK tool (baseline), Short-Form 12 Health Survey (SF-12), Shoulder Pain and Disability Index (SPADI), Numeric Pain Rating Score (NPRS) and Global Perceived Effect (GPE) scale at week 6, week 12 or endpoint were included. Data were collected from January 2019 to January 2020. Of these, 180 patients were eligible for the study. Of these, 139 completed the study and were included in the analysis.
Main outcome measures
Poor outcome was defined as: SF-12 score ≤33 (physical health), SPADI score ≥30% (disability in activity), NPRS score ≥3 (pain intensity) and GPE scale score ≥3 (patient-reported recovery).
Results
The area under the receiver operating characteristic curves for prediction of outcome were excellent for the SF-12, acceptable for the SPADI and NPRS, and showed no discrimination for the GPE scale. The optimal cut-off value for the Keele STarT MSK score to discriminate between low and medium/high risk groups was ≥5.
Conclusions
The Keele STarT MSK tool is able to predict the risk of poor outcome in patients with non-specific shoulder complaints in primary care physiotherapy clinics. Further research is needed to establish whether stratified care (subgrouping and targeted treatment) is more efficient.
Contribution of paper
- The results of this study confirm the applicability of the Keele STarT MSK tool in patients with non-specific shoulder complaints in the Netherlands.
- The optimal cut-off value for this target group was determined and corresponds to the previous results described by Van den Broek et al. [20].
- By applying the Keele Start MSK tool, the patient with shoulder complaints is better screened for his complaints. This allows the patient to be referred to the right healthcare provider to receive the right care.
