Background

Work disability due to low back pain (LBP) is a global concern, resulting in significant healthcare costs and welfare payments. In recognition of this, recent UK policy calls for healthcare to become more ‘work-focused’. However, an ‘evidence-policy’ gap has been identified, resulting in uncertainty about how this is to be achieved. Clear, evidence-based recommendations relevant to both policy-makers and healthcare practitioners are required.

Methods

A policy theory approach combining scientific evidence with governance principles in a pragmatic manner was undertaken. This entailed extracting evidence from a recent review of the system influences on work disability due to LBP* (focused specifically on the healthcare system) and appraising it alongside the most recent review evidence on the implementation of clinical guidance, and policy material aimed at developing work-focused healthcare.

Background

Current policy and practice aimed at tackling work disability due to low back pain is largely aligned with the Psychosocial Flags Framework, which focuses on addressing individual beliefs and behaviours (yellow and blue flags). However, our understanding of the systemic and contextual factors (black flags) that are also proposed to act as obstacles within this Framework is under-represented, resulting in a disproportionate evidence base and suboptimal interventions.

Methods

A ‘best-evidence’ synthesis was conducted to collate the evidence on those ‘black flags’ proposed to be the most important: compensatory systems (worker's compensation and disability benefits), healthcare provider systems and ‘significant others’ (spouse/partner/close family members). A systematic search of scientific and grey literature databases was performed, and the validity and merit of the available evidence was assessed using a system adapted from previous large-scale policy reviews conducted in this field.

Background: Evidence-based occupational health guidelines recommend that some form of case-management approach, involving getting ‘all players onside’, should be implemented for control of absence due to back pain; this approach has not been formally tested in the UK.

Methods/Results: A quasi-experimental controlled trial was conducted at selected sites of a large pharmaceutical company in the UK. The experimental intervention, delivered by occupational health nurses working to a guidelines-based protocol, was implemented at two manufacturing sites (n=1,435). Three matched sites acted as controls, delivering management as usual (n=1,483). Absence data were collected for both experimental and control sites for the two years prior to, and the two years during, the intervention period.

The intended early contact (within first week) of workers absent with musculoskeletal disorders only occurred at one experimental site; the control sites had no procedure for early contact. Absence rates improved over the four years at the intervention sites compared with the control sites: a decrease of 2.0 v an increase of 0.9 days/1000 working hours. The median return-to-work time for early intervention compared with controls was 4 days v 5 days (P=NS). Considering return-to-work time irrespective of whether the intervention was delivered early or late, the median durations were also 4 days v 5 days (P< 0.05). When looking at work retention over 12 months, the median duration of subsequent absence for early intervention was 5 days compared with 11 days for controls (P=NS). For the larger number of workers receiving a late intervention, the median duration of subsequent absence was median 4 days v 11 days for controls (P< 0.05).

Conclusion: The data consistently favoured a reduction in absence at the experimental sites, but organisational obstacles (black flags) precluded statistically significant results for early intervention. Implementation of certain guidelines principles (a supportive network with ‘all players onside’) can be effective for reducing absence.

Background: The influence of psychosocial factors on absence rates is incompletely understood; much research has been cross-sectional, involving a limited range of psychosocial variables. This paper reports a large prospective study of the relationship between psychosocial factors and absence rates due to low back pain across a multi-site UK pharmaceutical company.

Methods/Results: Baseline data were collected from 4,637 workers, and absence data over the ensuing 15 months were obtained from company records. In addition to demographic and historical variables, a wide range of psychosocial variables was included with a focus on occupational psychosocial factors, termed ‘blue flags’. Validated questionnaires were used to quantify job satisfaction, social support, attribution of cause, control over work, and organisation of work, with psychological distress as a ’yellow flag’. 176 workers took absence due to back pain during follow-up.

Previously defined cut-off scores were used to categorise hypothesised risk; scores beyond the cut-off point were considered detrimental, and the ‘flag’ was considered to be ‘flying’. Odds ratios (OR) were calculated to explore the association between the flags and taking sick leave; a statistically significant association was found with ORs between 1.5 and 2.9. The cut-off scores were then used to compare the length of absence between workers who had zero flags flying and those who had one or more flags flying. Absence over the ensuing 15 months was significantly longer for those people who had one or more flags flying (mean 10.6 days compared with 6.1 days, P< 0.05). There was a trend for longer absence with more flags flying.

Conclusion: This prospective study confirms the influence of blue, as well as yellow, psychosocial flags on both the taking of sick leave and the subsequent length of absence. This supports their hypothesised role as obstacles to recovery that might be suitable targets for occupational health interventions.

Objective: To implement an early occupational intervention which tackles the psychosocial factors (yellow and blue flags) that influence recovery from occupational back pain.

Design: An early, psychosocial, occupational health nurse-led intervention using a basic ‘counselling’ technique that reinforces evidence-based messages and advice, along with availability of modified work.

Subjects: 206 workers from a sample of Glaxosmithkline sites who took absence due to back pain.

Outcome measures: Duration of presenting absence.

Results: The target for contacting the worker was achieved at Site 1 (mean 3 days), but not Site 2 (mean 12 days). Results showed that late contact of absent workers (> 1 week) was significantly associated with both longer presenting absence and fewer recipients of the psychosocial intervention, compared with early contact. Preliminary results show that the psychosocial intervention (irrespective of early or late contact) reduces the length of presenting absence by half.

Conclusions: The lack of early contact at Site 2 was due to local sickness absence management differences. This study reveals a third class of obstacles to recovery – organisational policies (black flags) – that can negate the effect of occupational rehabilitation programs.

Study design: Cross-sectional questionnaire-based workforce survey together with collection of retrospective data on work absence.

Objectives: To determine if psychosocial ‘blue flags’ are related to back pain and/or sickness absence due to back pain.

Summary of background: The original description of the psychosocial ‘yellow flags’ for back pain chronicity included a mixture of individual psychological parameters and parameters related to perceptions about work and the workplace. It has recently been suggested that these latter parameters should be considered separate and distinct from the individual parameters , and can be termed ‘blue flags’. To date, however, there has been no attempt to explore the specific relationship between the blue and yellow flags or their relative relationship to symptoms and disability.

Methods: The workforce of a large multi-site company was invited to complete a booklet of questionnaires, which included the standard Nordic instrument for obtaining back pain data, and specific instruments to obtain data on ‘yellow’ and ‘blue’ psychosocial flags. The blue flags included psychosocial aspects of work, attribution and elements from the demand/control model, with psychological distress used as a yellow flag comparator. Of the 7,500 workers, 60% responded. Sickness absence records identified workers who had taken absence for back pain. The exploration of the data involved determining statistically significant relationships between psychosocial scores and both back pain history and absence. Appropriate statistical procedures were then used to establish cut-off points for the psychosocial variables. Odds ratios were calculated for two particular outcome variables: self-reported back pain in the previous 12 months and recorded absence over the same period.

Results: Cut-off points were established for each variable, along with the odds ratio (OR) that this score or a score above or below (depending on the scale direction) is associated with reports of back pain or absence. The ORs for psychological distress were 1.9 and 2.4 respectively for LBP and absence in the last 12 months. The ORs for the blue flag variables varied from 1.1 to 1.5 for LBP and from 1.8 to 3.2 for absence.

Conclusions: The psychosocial blue flags reported here are statistically significantly related both to reported back pain and absence. The effect size is less than that for distress in respect of back pain, but variously higher and lower for absence. Whilst prospective studies are needed to determine cause/effect, the results offer tentative support for the suggestion that blue flags should be addressed in clinical interventions.

Traditional biomedical/ergonomic occupational interventions to reduce work loss show limited success. Attention is now focussing on tackling the psychosocial factors that influence occupational back pain.

A workforce survey of Glaxo Smith Kline (reported to the Society last year) established that clinical and occupational psychosocial factors (yellow & blue flags) act independently and may represent obstacles to recovery. Consequently, a nurse-led intervention was devised. Occupational nurses at two manufacturing sites were trained to identify both clinical and occupational psychosocial factors, and address them using a basic ‘counselling’ technique that reinforces evidence-based messages and advice, along with availability of modified work. The program should ideally be implemented within the first days of absence, with ‘case-management’ by the nurse for a further 4 weeks. Control sites simply offer ‘usual management’. Outcomes at 12-month follow-up are rates for work loss/work retention.

The target for contacting the worker (3 days) was achieved at one site, but not the other (mean 12 days), thus exerting a differential delay in delivering the intervention. The lack of early identification at the second site was due to local reporting/recording mechanisms. This study reveals a third class of obstacles to recovery – black flags – company policies/procedures that can impede occupational rehabilitation programs.
