STarT Back Screening Tool

Objective (9-item tool)

The Keele STarT Back Screening Tool (SBST) (9-item version) is a brief validated tool, designed to screen primary care patients with low back pain for prognostic indicators that are relevant to initial decision making [1].

Intended Population (9-item tool)

Primary care patients with low back pain [1].

Method of Use (9-item tool)

The STarT Back Screening Tool helps primary care clinicians (GPs, physiotherapists etc) to group patients into three categories of risk of poor outcome (persistent disabling symptoms) - low, medium, and high-risk. By being able to categorise patients into these 3 groups, clinicians are then able to target interventions to each sub-group of patients to help outcome [1].

The STarT Back Screening Tool is available in a number of languages including: English, Dutch, French, Spanish, Danish and Welsh (Keele University n.d). The tool produces two scores: overall scores and distress subscale scores [2].

  • The distress subscale score is used to identify the high-risk subgroup. To score this subscale add the last 5 items; fear, anxiety, catastrophising, depression and bothersomeness (bothersomeness responses are positive for 'very much' or 'extremely' bothersome back pain). Subscale scores range from 0 to 5 with patients scoring 4 or 5 being classified into the high-risk subgroup [1].
  • The overall score is used to separate the low risk patients from the medium-risk subgroups. Scores range from 0-9 and are produced by adding all positive items; patients who achieve a score of 0-3 are classified into the low-risk subgroup and those with scores of 4-9 into the medium-risk subgroup [1].

Evidence (9-item tool)

The STarT Back trial [3] compared the clinical and cost effectiveness of stratified management approach; allocating patients to different treatment pathways based on their prognosis (low, medium, or high risk of poor outcome); with that of current best practice. The trial demonstrated that this new model results in greater health benefits, achieved at a lower average health-care cost, with an average saving to health services of £34.39 per patient and societal savings of £675 per patient [1].

The Keele SBST 6-Item Version

The Keele SBST 6-item version includes 6 of the same items as the original 9-item version, with 3 items excluded (fear, anxiety and pain elsewhere), making it quicker it use. However, [1] have reported that their research (unpublished) shows that the 6-item version is only able to allocate patients to one of two subgroups (low risk or high risk). Patients who score 3 or more items positively have a high-risk of persistent disabling low back pain.

The Keele SBST 9-Item Clinical Measurement Tool

The Keele SBST 9-item clinical measurement version has been designed to help physiotherapists objectively measure the severity of the domains screened by the original 9-item version. When repeated measures are used this enables an objective marker of change over time to be made for individual items; essentially this version can be used as an outcome measure in addition to being used to subgroup patients in the same way as the original 9-item version. In order to be able to use this version to subgroup patients in the same way as the original 9-item version, cut-offs have been established for each item. The cut-off points that equate to an agree/positive score on this version for subgrouping are:

  • Leg pain - 'moderately' or more
  • Shoulder/neck - slightly or more
  • Dressing - 5 or more
  • Walking - 5 or more
  • Fear - 7 or more
  • Worry - 3 or more
  • Catastrophising - 6 or more
  • Mood - 7 or more
  • Bothersomeness - 'very' or more [1]

The authors[1] suggest it is very easy to produce an acetate using these cut-off that you place over the questionnaire to quickly enable you to score the clinical measurement tool for subgrouping purposes.

The Keele SBST 5-Item Generic Condition Tool

The Keele SBST 5-item generic condition version is the 9-item psychosocial subscale adapted to screen/identify distress in other conditions. Scores range from 0-5 with patients scoring 4 or 5 being classified as a high psychosocial risk [1].

[1] have stated that for now they are unable to recommend the use of a modified version of the SBST (including the 5-item generic condition version) for conditions other than low back pain.
