Abstract Objective Given the significant costs of reduced productivity (presenteeism) in comparison to absenteeism, and overall societal costs, presenteeism has a potentially important role to play ...in economic evaluations. However, these costs are often excluded. The objective of this study is to review applied cost of illness studies and economic evaluations to identify valuation methods used for, and impact of including presenteeism costs in practice. Methods A structured systematic review was carried out to explore (i) the extent to which presenteeism has been applied in cost of illness studies and economic evaluations and (ii) the overall impact of including presenteeism on overall costs and outcomes. Potential articles were identified by searching Medline, PsycINFO and NHS EED databases. A standard template was developed and used to extract information from economic evaluations and cost of illness studies incorporating presenteeism costs. Results A total of 28 studies were included in the systematic review which also demonstrated that presenteeism costs are rarely included in full economic evaluations. Estimation and monetisation methods differed between the instruments. The impact of disease on presenteeism whilst in paid work is high. Conclusions The potential impact of presenteeism costs needs to be highlighted and greater consideration should be given to including these in economic evaluations and cost of illness studies. The importance of including presenteeism costs when conducting economic evaluation from a societal perspective should be emphasised in national economic guidelines and more methodological work is required to improve the practical application of presenteeism instruments to generate productivity cost estimates.
Microbial keratitis (MK) is the most common non-surgical ophthalmic emergency admission in the UK. However, few prospective health-economic studies of MK have been performed, and no specific ...healthcare resources group (HRG) code exists. This study is designed to determine the feasibility of a data collection tool derived from the microbiology ophthalmology group (MOG) clinical record form, to enable quantification of direct costs of inpatient care, as well as prospective capture of epidemiological data relating to outcomes of MK.
Clinical, demographic and economic data were collected retrospectively between January and December 2013 for 101 consecutive patients admitted with MK, using an adaption of the MOG toolset. The direct cost of admission (COA) was calculated using national reference costs and compared to actual income to generate profit/deficit profiles for individual patients. Indices of multiple deprivation were used to assess effect of deprivation on the COA.
The total income generated through discharge coding was £252,116, compared to a COA of £357,075, yielding a deficit of £104,960 (median: £754 per patient). The cost deficit increased significantly with length of stay (LOS, p < 0.001), whilst patients with short LOS were income generators; cost neutrality occurred at 4.8 days. Greater socioeconomic deprivation was also associated with a significantly higher cost deficit.
LOS is the key driver for COA of care for MK admissions. Protocols should encourage discharge of patients who are able to self-administer treatment after the sterilisation phase. The MOG-derived data collection toolset captures pertinent clinical data for quantification of COA. Further development into a multiuser and multisite platform is required for robust prospective testing, together with expansion to capture indirect costs of disease burden, including impact of treatment, visual morbidity and quality of life.
Back pain is a common and costly health problem worldwide. There is yet a lack of consistent methodologies to estimate the economic burden of back pain to society.
To systematically evaluate the ...methodologies used in the published cost of illness (COI) literature for estimating the direct and indirect costs attributed to back pain, and to present a summary of the estimated cost burden.
Six electronic databases were searched to identify COI studies of back pain published in English up to February 2021. A total of 1,588 abstracts were screened, and 55 full-text studies were subsequently reviewed. After applying the inclusion criteria, 45 studies pertaining to the direct and indirect costs of back pain were analysed.
The studies reported data on 15 industrialised countries. The national cost estimates of back pain in 2015 USD ranged from $259 million ($29.1 per capita) in Sweden to $71.6 billion ($868.4 per capita) in Germany. There was high heterogeneity among the studies in terms of the methodologies used for analysis and the resulting costs reported. Most of the studies assessed costs from a societal perspective (n = 29). The magnitude and accuracy of the reported costs were influenced by the case definition of back pain, the source of data used, the cost components included and the analysis method. Among the studies that provided both direct and indirect cost estimates (n = 15), indirect costs resulting from lost or reduced work productivity far outweighed the direct costs.
Back pain imposes substantial economic burden on society. This review demonstrated that existing published COI studies of back pain used heterogeneous approaches reflecting a lack of consensus on methodology. A standardised methodological approach is required to increase credibility of the findings of COI studies and improve comparison of estimates across studies.
There is limited research on the economic burden of low back-related leg pain, including sciatica. The aim of this study was to describe healthcare resource utilisation and factors associated with ...cost and health outcomes in primary care patients consulting with symptoms of low back-related leg pain including sciatica.
This study is a prospective cohort of 609 adults visiting their family doctor with low back-related leg pain, with or without sciatica in a United Kingdom (UK) Setting. Participants completed questionnaires, underwent clinical assessments, received an MRI scan, and were followed-up for 12-months. The economic analysis outcome was the quality-adjusted life year (QALY) calculated from the EQ-5D-3 L data obtained at baseline, 4 and 12-months. Costs were measured based on patient self-reported information on resource use due to back-related leg pain and results are presented from a UK National Health Service (NHS) and Societal perspective. Factors associated with costs and outcomes were obtained using a generalised linear model.
Base-case results showed improved health outcomes over 12-months for the whole cohort and slightly higher QALYs for patients in the sciatica group. NHS resource use was highest for physiotherapy and GP visits, and work-related productivity loss highest from a societal perspective. The sciatica group was associated with significantly higher work-related productivity costs. Cost was significantly associated with factors such as self-rated general health and care received as part of the study, while quality of life was significantly predicted by self-rated general health, and pain intensity, depression, and disability scores.
Our results contribute to understanding the economics of low back- related leg pain and sciatica and may provide guidance for future actions on cost reduction and health care improvement strategies.

Introduction The choice of the most appropriate approach to valuing productivity loss has received much debate in the literature. The friction cost approach has been proposed as a more appropriate ...alternative to the human capital approach when valuing productivity loss, although its application remains limited. This study reviews application of the friction cost approach in health economic studies and examines how its use varies in practice across different country settings. Methods A systematic review was performed to identify economic evaluation studies that have estimated productivity costs using the friction cost approach and published in English from 1996 to 2013. A standard template was developed and used to extract information from studies meeting the inclusion criteria. Results The search yielded 46 studies from 12 countries. Of these, 28 were from the Netherlands. Thirty-five studies reported the length of friction period used, with only 16 stating explicitly the source of the friction period. Nine studies reported the elasticity correction factor used. The reported friction cost approach methods used to derive productivity costs varied in quality across studies from different countries. Conclusions Few health economic studies have estimated productivity costs using the friction cost approach. The estimation and reporting of productivity costs using this method appears to differ in quality by country. The review reveals gaps and lack of clarity in reporting of methods for friction cost evaluation. Generating reporting guidelines and country-specific parameters for the friction cost approach is recommended if increased application and accuracy of the method is to be realized.
This study aimed to evaluate whether prompting general practitioners (GPs) to routinely assess and manage anxiety and depression in patients consulting with osteoarthritis (OA) improves pain ...outcomes.
We conducted a cluster randomised controlled trial involving 45 English general practices. In intervention practices, patients aged ≥45 y consulting with OA received point-of-care anxiety and depression screening by the GP, prompted by an automated electronic template comprising five questions (a two-item Patient Health Questionnaire-2 for depression, a two-item Generalized Anxiety Disorder-2 questionnaire for anxiety, and a question about current pain intensity 0-10 numerical rating scale). The template signposted GPs to follow National Institute for Health and Care Excellence clinical guidelines for anxiety, depression, and OA and was supported by a brief training package. The template in control practices prompted GPs to ask the pain intensity question only. The primary outcome was patient-reported current pain intensity post-consultation and at 3-, 6-, and 12-mo follow-up. Secondary outcomes included pain-related disability, anxiety, depression, and general health. During the trial period, 7,279 patients aged ≥45 y consulted with a relevant OA-related code, and 4,240 patients were deemed potentially eligible by participating GPs. Templates were completed for 2,042 patients (1,339 31.6% in the control arm and 703 23.1% in the intervention arm). Of these 2,042 patients, 1,412 returned questionnaires (501 71.3% from 20 intervention practices, 911 68.0% from 24 control practices). Follow-up rates were similar in both arms, totalling 1,093 (77.4%) at 3 mo, 1,064 (75.4%) at 6 mo, and 1,017 (72.0%) at 12 mo. For the primary endpoint, multilevel modelling yielded significantly higher average pain intensity across follow-up to 12 mo in the intervention group than the control group (adjusted mean difference 0.31; 95% CI 0.04, 0.59). Secondary outcomes were consistent with the primary outcome measure in reflecting better outcomes as a whole for the control group than the intervention group. Anxiety and depression scores did not reduce following the intervention. The main limitations of this study are two potential sources of bias: an imbalance in cluster size (mean practice size 7,397 intervention versus 5,850 control) and a difference in the proportion of patients for whom the GP deactivated the template (33.6% intervention versus 27.8% control).
In this study, we observed no beneficial effect on pain outcomes of prompting GPs to routinely screen for and manage comorbid anxiety and depression in patients presenting with symptoms due to OA, with those in the intervention group reporting statistically significantly higher average pain scores over the four follow-up time points than those in the control group.

Many pregnant women experience low back pain. Acupuncture appears to be a safe, promising intervention but evidence is needed about its clinical effectiveness and cost-effectiveness.
To assess the ...feasibility of a future large randomised controlled trial (RCT) testing the additional benefit of adding acupuncture to standard care (SC) for pregnancy-related back pain.
Phase 1: a questionnaire survey described current care for pregnancy-related back pain. Focus groups and interviews with midwives, physiotherapists and pregnant women explored acceptability and feasibility of acupuncture and the proposed RCT. Phase 2: a single-centre pilot RCT. Participants were identified using six methods and randomised to SC, SC plus true acupuncture or SC plus non-penetrating acupuncture.
Phase 1: 1093 physiotherapists were surveyed and 15 midwives, 21 physiotherapists and 17 pregnant women participated in five focus groups and 20 individual interviews. Phase 2: 125 women with pregnancy-related back pain participated.
SC: a self-management booklet and onward referral for one-to-one physiotherapy (two to four sessions) for those who needed it. SC plus true acupuncture: the self-management booklet and six to eight treatments with a physiotherapist comprising true (penetrating) acupuncture, advice and exercise. SC plus non-penetrating acupuncture: the self-management booklet and six to eight treatments with a physiotherapist comprising non-penetrating acupuncture, advice and exercise.
Pilot RCT outcomes included recruitment rates, treatment fidelity, follow-up rate, patient-reported pain and function, quality of life and health-care resource use. Birth and neonatal outcomes were also assessed. Staff overseeing outcome data collection were blind to treatment allocation.
Phase 1: 629 (57.5%) physiotherapists responded to the survey, 499 were experienced in treating pregnancy-related back pain and reported 16 advice and 18 treatment options. Typical treatment comprised two to four individual sessions of advice and exercise over 6 weeks. Acupuncture was reported by 24%. Interviews highlighted the impact of back pain and paucity of effective interventions. Women and midwives strongly supported a RCT and expressed few concerns. Physiotherapists' concerns about acupuncture in pregnancy informed a training programme prior to the pilot RCT. Phase 2: We recruited 125 of 280 potentially eligible women (45%) in 6 months and randomised 41 to SC and 42 each to the SC plus true acupuncture and SC plus non-penetrating acupuncture arms. Analysis was conducted with 124 participants (41, 42 and 41, respectively) as one participant was randomised in error. Three of six recruitment methods were the most successful. In total, 10% of women (n = 4) randomised to SC alone accessed one-to-one physiotherapy and received an average of two treatments. The average number of treatments was six for both SC plus true acupuncture and SC plus non-penetrating acupuncture. Treatments were in line with protocols. Eight-week follow-up was 74%. Patient-reported outcomes (pain, function and quality of life) favoured the addition of acupuncture. There was no evidence of serious adverse events on mothers or birth and neonatal outcomes. The Pelvic Girdle Questionnaire was found to be an appropriate outcome measure for a future trial.
A future main RCT is feasible and would be welcomed by women and clinicians. Longer-term follow-up and further follow-up efforts are recommended for a main trial.

Background and objectivesThe health workforce (HWF) is at the core of ensuring an efficient, effective and functional health system, but it faces chronic underinvestment. This paper presents a fiscal ...space analysis of 20 countries in East and Southern Africa to generate sustained evidence-based advocacy for significant and smarter investment in the HWF.MethodsWe adapted an established empirical framework for fiscal space analysis and applied it to the HWF. Country-specific data were curated and triangulated from publicly available datasets and government reports to model the fiscal space for the HWF for each country. Based on the current knowledge, three scenarios (business as-usual, optimistic and very optimistic) were modelled and compared.FindingsA business-as-usual scenario shows that the cumulative fiscal space across the 20 countries is US$12.179 billion, which would likely increase by 28% to US$15.612 billion by 2026 but varies across countries—the highest proportional increases expected in Seychelles (117%) and Mozambique (69%) but lowest in Zambia (15%). Under optimistic assumptions, allocating an additional 1.5% of gross domestic product (GDP) to health even without further prioritising the proportional allocation to the wage bill could boost the cumulative fiscal space for HWF by US$4.639 billion. In a very optimistic scenario of a 1.5% increase in health expenditure as a proportion of GDP and further prioritisation of HWF within the health expenditure, the cumulative fiscal space for HWF could improve by some 105%—ranging from 24% in Zambia to 330% in Lesotho.ConclusionSmall increments in government health expenditure and increased prioritisation of HWF in funding in tandem with the 57% global average could potentially increase the fiscal space for HWF by at least 32% in 11 countries. Unless the HWF is sufficiently prioritised within the health expenditures, only increasing the overall health expenditure to even recommended levels would still portend severe underinvestment in HWF amid unabating shortages to deliver health services. Thus, HWF strategies and investment plans should include fiscal space analysis to deepen advocacy for sustainable investment in the HWF.
Background
Usual primary care for patients with musculoskeletal pain varies widely and treatment outcomes are suboptimal. Stratified care involves targeting treatments according to patient subgroups, ...in the hope of maximising treatment benefit and reducing potential harm or unnecessary interventions. This programme developed a new prognostic stratified primary care approach, where treatments are matched to a patient’s risk of future persistent pain and disability based on a prognostic tool, and compared this with usual care.
Objectives
In four linked work packages, we refined and validated a prognostic tool the Keele STarT MSK (Subgrouping for Targeted Treatment for Musculoskeletal pain) Tool to identify risk of poor outcome and defined cut-off scores to distinguish patient risk subgroups (work package 1); defined and agreed new matched treatment options for each risk subgroup and developed a support package for delivery of stratified care (work package 2); tested the feasibility of delivering the stratified approach through a pilot randomised controlled trial and externally validated the prognostic tool (work package 3); and tested the effectiveness of the approach by comparing the clinical effectiveness and cost-effectiveness of stratified primary care with that of usual care through a cluster randomised controlled trial with embedded health economic and qualitative studies (work package 4).
Setting
General practices and linked musculoskeletal services in the West Midlands of England, UK.
Participants
Adults registered with participating practices consulting with back, neck, shoulder, knee or multisite musculoskeletal pain, and clinicians involved in managing these patients.
Design
The programme included the following work packages: work package 1 – a prospective cohort study in 12 practices; work package 2 – an evidence synthesis, consensus group workshops and qualitative studies; work package 3 – a cluster feasibility and pilot trial in eight practices; and work package 4 – a main cluster randomised controlled trial in 24 practices, with health economic analyses and process evaluation.
Interventions
Stratified care comprised training general practitioners to use the tool and match patients to treatment options depending on their risk subgroup. Usual care comprised usual non-stratified primary care without formal stratification tools.
Main outcome measures
Cohort primary end points included function (Short Form questionnaire-36 items physical component score) and pain intensity (numerical rating scale). The trial primary end point for patient outcomes was pain intensity (monthly for 6 months) (0–10 numerical rating scale). An audit of primary care electronic medical records evaluated the impact of stratified care on clinical decision-making regarding patient management.
Results
Work package 1 – the cohort study (
n
= 1890 patients) refined and validated a new 10-item tool with which to stratify patients with the five most common musculoskeletal pain presentations. The tool subgroups patients into three strata with different characteristics and prognoses. Work package 2: 17 treatment options were recommended – four for patients at low risk, 10 for patients at medium risk and 15 for patients at high risk. Work package 3: the feasibility and pilot trial included 524 patients, and the learning led to amendments to several tool items and a reduced set of treatments (14 in total). Work package 4: in the main trial, 1211 patients consented to data collection (534 in stratified care, 677 in usual care). Stratified primary care did not lead to statistically significant differences in the primary patient outcome of pain intensity stratified care mean 4.4 (standard deviation 2.3) vs. usual care mean 4.6 (standard deviation 2.4); adjusted mean difference –0.16, 95% confidence interval –0.65 to 0.34;
p
= 0.535. Where differences were observed, these were largely isolated to patients at high risk of poor outcome (the smallest subgroup), in favour of stratified care. Positive differences were, however, observed in general practitioner clinical decision-making, with increased provision of written self-management information and referrals to physiotherapy, plus reductions in prescription medication. The economic evaluation demonstrated that costs of care were similar across trial arms (£6.85, 95% confidence interval –£107.82 to £121.54 more for stratified care), with incremental quality-adjusted life-years of 0.0041 (95% confidence interval –0.0013 to 0.0094), representing a net quality-adjusted life-year gain. Stratified care was associated with an incremental cost-effectiveness ratio of £1670 per additional quality-adjusted life-year gained. At a willingness-to-pay threshold (λ) of £20,000 per quality-adjusted life-year, the incremental net monetary benefit was £132 and the probability of stratified care being cost-effective was approximately 73%. The very small differences suggest caution in the interpretation of this result. The qualitative findings revealed that general practitioners felt stratified care had a positive role in informing clinical decision-making, helped them to give greater attention to psychosocial issues and take a more functional approach, and facilitated negotiations with patients about treatment options such as imaging.
Limitations
The randomised controlled trial was not powered to detect differences between stratified and usual care for patients in each risk subgroup (low, medium and high) nor with each different musculoskeletal pain presentation. The stratified care electronic medical record template ‘fired’ only once per patient.
Conclusions
The Keele STarT MSK Tool is a valid instrument with which to discriminate between, and predict outcomes of, primary care patients with musculoskeletal pain. Although the randomised trial showed no significant benefit in patient-reported outcomes compared with usual care, some aspects of clinical decision-making improved and the approach was cost-effective.
Future work
The Keele STarT MSK Tool has been shared with over 1000 tool license requestees, leading to other work. Trial data sets have also led to other work, developing personalised prognostic models for back and neck pain patients (the European Union-funded Back-UP project). The challenge remains how to improve outcomes for primary care patients with musculoskeletal pain.
