The cost effectiveness of NHS physiotherapy support for occupational health (OH) services.

BACKGROUND: Musculoskeletal pain is detrimental to quality of life (QOL) and disruptive to activities of daily living. It also places a major economic burden on healthcare systems and wider society. In 2006, the Welsh Assembly Government (WAG) established a three tiered self-referral Occupational Health Physiotherapy Pilot Project (OHPPP) comprising: 1.) telephone advice and triage, 2.) face-to-face physiotherapy assessment and treatment if required, and 3.) workplace assessment and a return-to-work facilitation package as appropriate. This study aimed to evaluate the feasibility and cost-effectiveness of the pilot service. METHODS: A pragmatic cohort study was undertaken, with all OHPPP service users between September 2008 and February 2009 being invited to participate. Participants were assessed on clinical status, yellow flags, sickness absence and work performance at baseline, after treatment and at 3 month follow up. Cost-effectiveness was evaluated from both top-down and bottom-up perspectives and cost per Quality Adjusted Life Year (cost/QALY) was calculated. The cost-effectiveness analysis assessed the increase in service cost that would be necessary before the cost-effectiveness of the service was compromised. RESULTS: A total of 515 patients completed questionnaires at baseline. Of these, 486 were referred for face to face assessment with a physiotherapist and were included in the analysis for the current study. 264 (54.3%) and 199 (40.9%) were retained at end of treatment and 3 month follow up respectively. An improvement was observed at follow up in all the clinical outcomes assessed, as well as a reduction in healthcare resource usage and sickness absence, and improvement in self-reported work performance. Multivariate regression indicated that baseline and current physical health were associated with work-related outcomes at follow up. The costs of the service were £194-£360 per service user depending on the method used, and the health gains contributed to a cost/QALY of £1386-£7760, which would represent value for money according to current UK thresholds. Sensitivity analyses demonstrated that the service would remain cost effective until the service costs were increased to 160% per user. CONCLUSIONS: This pragmatic evaluation of the OHPPP indicated that it was likely to be feasible in terms of service usage and could potentially be cost effective in terms of QALYs. Further, the study confirmed that improving physical health status for musculoskeletal pain patients is important in reducing problems with work capacity and related costs. This study suggests that this type of service could be potentially be useful in reducing the burden of pain and should be further investigated, ideally via randomised controlled trials assessing effectiveness and cost-effectiveness.

Feeling healthy? A survey of physical and psychological wellbeing of students from seven universities in the UK.

University students' physical and psychological health and wellbeing are important and comprise many variables. This study assessed perceived health status in addition to a range of physical and psychological wellbeing indicators of 3,706 undergraduate students from seven universities in England, Wales and Northern Ireland. We compared differences in these variables across males and females, and across the participating universities. The data was collected in 2007-2008. A self-administered questionnaire assessed socio-demographic information (e.g., gender, age), self-reported physical and psychological health data, as well as questions on health awareness, health service use, social support, burdens and stressors and university study related questions. While females generally reported more health problems and psychological burdens, male students felt that they received/had fewer persons to depend on for social support. The comparisons of health and wellbeing variables across the different universities suggested some evidence of 'clustering' of the variables under study, whereby favourable situations would be exhibited by a cluster of the variables that is encountered at some universities; and conversely, the clustering of less favourable variables as exhibited at other universities. We conclude that the level of health complaints and psychological problems/burdens is relatively high and calls for increased awareness of university administrators, leaders and policy makers to the health and well-being needs of their students. The observed clustering effects also indicated the need for local (university-specific) health and wellbeing profiles as basis and guidance for relevant health promotion programmes at universities.

Does the association between depressive symptomatology and physical activity depend on body image perception? A survey of students from seven universities in the UK.

This cross-sectional study assessed the association between depression and PA in university students of both genders and the role of body image perception as a potential effect modifier. Undergraduate students (N = 3706) from seven universities in the UK completed a self-administered questionnaire that assessed sociodemographic information; a range of health, health behaviour and health awareness related factors; the modified version of Beck's Depression Inventory (M-BDI); educational achievement, and different levels of physical activity (PA), such as moderate PA (at least 5 days per week moderate exercise of at least 30 minutes), and vigorous PA (at least 3 days per week vigorous exercise of at least 20 minutes). Only 12.4% of the sample achieved the international recommended level for moderate PA, and 33.1% achieved the recommendations for vigorous PA. Both moderate and vigorous PA were inversely related to the M-BDI score. Physically active students, regardless of the type of PA, were significantly more likely to perceive their health as good, to have higher health awareness, to perform strengthening exercises, and to be males. The stratified analyses indicated that the association between depression and PA differed by body image. In students perceiving their body image as 'just right', moderate (>4th percentile) and high (>5th percentile) M-BDI scores were inversely related to vigorous PA. However, in students who perceived their body image as 'overweight', the inverse association was only significant in those with high M-BDI scores. We conclude that the positive effect of PA on depression could be down modulated by the negative impact of a 'distorted' body image on depression. The practical implications of these findings are that PA programmes targeting persons with depressive symptoms should include effective components to enhance body image perception.

Exploring the role of economics in prioritization in public health: what do stakeholders think?

BACKGROUND: Debates surrounding the use of conventional approaches in public health and the existence of perceived barriers to using the results of economic evaluations have led to questions posed as to how to establish priorities within public health schemes. The aims of this study were therefore to explore the feasibility and validity of economic evaluation techniques in developing priorities within public health programmes and consider the extent to which different presentational approaches are likely to be incorporated into decision-making, from perspectives of relevant stakeholders. METHODS: An advisory board, representative of potential users of economic evaluations, was set up to identify preferences for how findings from economic evaluations might be presented to decision makers and to test the impact of different approaches, different outputs and different presentational styles. The board was divided into two groups, each of which was given three hypothetical 'scenarios' to consider. The scenarios comprised descriptions of methods and outputs, with costs, effects, target population and context of intervention constant across all scenarios. RESULTS: The perceived validity of estimates of effectiveness was vitally important, along with sufficient information to gauge whether designs were appropriate and to assess implementation practicalities. Cost-benefit analysis and cost-utility analysis were the preferred approaches despite their complexity, although participants required benchmarks to place net-benefit estimates from cost-benefit analyses into context. CONCLUSION: Further research is required to substantiate and build on these preliminary findings and collaborations between economists and policy makers are needed to develop clear, rigorous and standard guidance relating to economic evaluation, recognizing the diversity of public health strategies.

Measuring the impact and costs of a universal group based parenting programme: protocol and implementation of a trial.

BACKGROUND: Sub-optimal parenting is a common risk factor for a wide range of negative health, social and educational outcomes. Most parenting programmes have been developed in the USA in the context of delinquency prevention for targeted or indicated groups and the main theoretical underpinning for these programmes is behaviour management. The Family Links Nurturing Programme (FLNP) focuses on family relationships as well as behaviour management and is offered on a universal basis. As a result it may be better placed to improve health and educational outcomes. Developed in the UK voluntary sector, FLNP is popular with practitioners, has impressed policy makers throughout the UK, has been found to be effective in before/after and qualitative studies, but lacks a randomised controlled trial (RCT) evidence base. METHODS/DESIGN: A multi-centre, investigator blind, randomised controlled trial of the FLNP with a target sample of 288 south Wales families who have a child aged 2-4 yrs living in or near to Flying Start/Sure Start areas. Changes in parenting, parent child relations and parent and child wellbeing are assessed with validated measures immediately and at 6 months post intervention. Economic components include cost consequences and cost utility analyses based on parental ranking of states of quality of life. Attendance and completion rates and fidelity to the FLNP course delivery are assessed. A nested qualitative study will assess reasons for participation and non-participation and the perceived value of the programme to families. By the end of May 2010, 287 families have been recruited into the trial across four areas of south Wales. Recruitment has not met the planned timescales with barriers including professional anxiety about families entering the control arm of the trial, family concern about video and audio recording, programme facilitator concern about the recording of FLNP sessions for fidelity purposes and delays due to the new UK research governance procedures. DISCUSSION: Whilst there are strong theoretical arguments to support universal provision of parenting programmes, few universal programmes have been subjected to randomised controlled trials. In this paper we describe a RCT protocol with quantitative and qualitative outcome measures and an economic evaluation designed to provide clear evidence with regard to effectiveness and costs. We describe challenges implementing the protocol and how we are addressing these. TRIAL REGISTRATION: Current Controlled Trials ISRCTN13919732.

Which test is best for Helicobacter pylori? A cost-effectiveness model using decision analysis.

GPs face a potential dilemma in deciding which test to use for detection of Helicobacter pylori. For patients with dyspepsia, the National Institute for Health and Clinical Excellence (NICE) advises primary care practitioners to adopt a 'test and treat' policy before considering a referral for gastroscopy. There are many ways of testing: serology, urea breath test, and faecal antigen test. NICE does not advocate any preferred single test for detecting H. pylori. In the current study a multi-stakeholder 2-day workshop was established to agree and populate a cost-effectiveness decision analysis model. The aim was to analyse the three types of tests available for H. pylori and to determine which is the most practical and cost effective. Agreement on the costs and diagnostic values to be entered into the decision-analytic model was achieved. Results indicate that the faecal antigen test was the most effective in terms of true outcomes and cost. One thousand virtual patients were allocated to each of the three tests. Serology had 903, urea breath test had 961, and the faecal antigen test had 968 true positive outcomes. Data indicate that the faecal antigen test is the preferable strategy for diagnosis of H. pylori in primary care. This has implications for implementing new testing processes and for commissioning new diagnostic pathways for use in primary care.
