Number of musculoskeletal pain sites leads to increased long-term healthcare contacts and healthcare related costs – a Danish population-based cohort study

BMC Health Services Research (2021)

Søren Mose Peter Kent Anne Smith Johan Hviid Andersen David Høyrup Christiansen

Abstract Background People with musculoskeletal pain seek more healthcare than the general population, however little is known about the long-term effect on healthcare use. The aim of this study was to examine the consequences of number of musculoskeletal pain sites on long-term care-seeking and healthcare-related costs and explore how health anxiety influences this relationship. Methods We conducted a Danish population-based longitudinal cohort study of 4883 participants combining self-reported survey data from 2008 with ten-year follow-up data from national health registers. Using a causal inference framework, we examined associations between number of pain sites (range 0–7)/level of health anxiety (high/low level) and face-to-face healthcare contacts/healthcare-related costs. Data were analyzed using negative binomial regression with generalized estimating equations. Regression models were adjusted for sex, age, duration of pain, level of education, comorbidity, personality traits, risk of depression, marital status, physical job exposure, and previous healthcare utilization. Results For each additional pain site general healthcare contacts (Incidence Rate Ratio (IRR): 1.04 (95% CI: 1.03–1.05)), healthcare-related costs (IRR: 1.06 (95% CI: 1.03–1.08) and musculoskeletal healthcare contacts (IRR: 1.11 (95% CI:1.09–1.14) increased. Those with high levels of health anxiety at baseline had a slightly higher number of general healthcare contacts (IRR 1.06 (1.01–1.11), independent of number of pain sites. However, level of anxiety did not influence the effect of number of pain sites on any healthcare use or cost outcomes. Conclusions We found evidence for a causal association between increasing number of pain sites and greater healthcare use and cost, and high levels of health anxiety did not increase the strength of this association. This suggests that number of pain sites could be a potential target for biopsychosocial interventions in order to reduce the need for future care-seeking.

Occupational and health-related risk factors for incident and recurrent back disorders in Danish fishers – a register-based study

Journal of Occupational and Environmental Medicine (2024)

Line Nørgaard Remmen Ulrich Halekoh David Høyrup Christiansen Kimmo Herttua Heidi Klakk

Background Fishers are at risk of back disorders due to their physically demanding work. The aim was to investigate risk factors for back disorders in fishers in Denmark. Methods All male Danish registered fishers between 1994 and 2017 were included. ICD-10 codes classified back disorders (M40-M54* and DM99.1-4*). A multistate model on a cause-specific cox regression model was conducted. Results Of 13,165 fishers included, 16% had a hospital contact with an incident back disorder, and 52% at least had 1 recurrent episode. Having worked in another occupation (HR 1.14; 95% CI: 1.02, 1.27) and another musculoskeletal disorder (HR 1.84; 95% CI: 1.69, 2.01) were significant risk factors for the incident back disorder. No risk factors were seen for recurrent episodes. Conclusions Risk factors for incident and recurrent back disorders were different; thus, episode-specific initiatives are needed to reduce back disorders among fishers.

Using a Shoulder Exoskeleton in Slaughterhouse Work: Expectations, Experiences, and Feasibility

Jeppe Frost David Høyrup Christiansen Annett Dalbøge Regine Grytnes

BACKGROUNDWork in the slaughterhouse industry increase the risk of shoulder disorders due to high occupational mechanical exposures. Assistive devices, such as exoskeletons, have been developed to reduce the mechanical exposures, but few studies have investigated exoskeleton´s feasibility, when used in a workplace setting.OBJECTIVESThe objective was to explore managers' and workers' expectations and experiences related to using a shoulder exoskeleton, and to evaluate its feasibility at a Danish slaughterhouse.PARTICIPANTSThe participants included 26 production line workers and their managers at a packaging department at a large slaughterhouse facility.METHODSIn a 5-month field study, data on worker´s expectations and experiences of using a shoulder exoskeleton, was compared to an existing assistive device (a 'lifting glove') and to working without any assistive device. Data was collected using semi-structured interviews, questionnaires, and on-site observations.RESULTSExpectations was that shoulder exoskeletons would reduce the mechanical exposure and strain in workers. Some managers also expected that workers could handle more weight/ produce more and that the need for job rotation could be reduced. Workers reported the exoskeleton to 'straighten the body', and reduced strain, but e others experienced no perceived support or found donning and doffing too time consuming.CONCLUSIONWe found different expectations as to what the shoulder exoskeleton should achieve. This could influence the evaluation of the feasibility of using a shoulder exoskeleton in slaughterhouse work. To facilitate the feasibility of exoskeletons it is important to explicate different expectations and to allow for individual tailoring in its implementation.

Development of the Prevent for Work questionnaire (P4Wq) for assessment of musculoskeletal risk in the workplace: part 1—literature review and domains selection

BMJ Open (2021)

Francesco Langella Steffan Wittrup Christensen Þorvaldur Skúli Pálsson Morten Høgh Nicolo Gagni

Objective This study aims to define appropriate domains and items for the development of a self-administered questionnaire to assess the risk of developing work-related musculoskeletal disorder (WMSD) and the risk of its progression to chronicity. Design Literature review and survey study. Setting and participants A literature review and a two-round interview with 15 experts in musculoskeletal pain were performed to identify the available domains for WMSD assessment. Interventions and outcome To ensure quality, only validated questionnaires were included for the Delphi process. A three-round Delphi method, with three round steps, was used to select the most pertinent and relevant domains and items. Results Nine questionnaires were identified through the expert discussion and literature review, comprising 38 candidate domains and 504 items. In the first round of the Delphi group, 17 domains reached more than 70% agreement and were selected. In the second round, 10 domains were rejected, while 11 were selected to complete the pool of domains. In the third and final round, 89 items belonging to 28 domains were defined as significant to develop a WMSDs risk assessment questionnaire. Conclusions No specific risk assessment questionnaires for WMSDs were identified from the literature. WMSD risk of presence and chronicity can be defined by an assessment tool based on the biopsychosocial model and the fear-avoidance components of chronic pain. The present study provides the formulation and operationalisation of the constructs in domains and items needed for developing and validating the questionnaire.

Predicting change in symptoms and function in patients with persistent shoulder pain: a prognostic model development study

BMC Musculoskeletal Disorders (2021)

Mathias Moselund Rønnow Thor André Brøndberg Stæhr David Høyrup Christiansen

Persistent shoulder pain causes considerable disruption of the individual's life and imposes high costs on healthcare and society. Well-informed treatment and referral pathways are crucial as unsuccessful interventions and longer duration of symptoms minimizes the likelihood of success in future interventions. Although physiotherapy is generally recommended as first line treatment, no prognostic model or clinical prediction rules exists to help guide the treatment of patients with persistent shoulder pain undergoing physiotherapy. Thus, the objective of this study was to develop a prognostic model to inform clinical decision making and predict change in symptoms and function in patients with persistent shoulder pain.

Responsiveness and Minimal Clinically Important Change: A Comparison Between 2 Shoulder Outcome Measures

Journal of Orthopaedic and Sports Physical Therapy (2015)

David Høyrup Christiansen Poul Frost Deborah Falla Jens Peder Haahr Lars Henrik Frich

Study Design A prospective cohort study nested in a randomized controlled trial. Objectives To determine and compare responsiveness and minimal clinically important change of the modified Constant score (CS) and the Oxford Shoulder Score (OSS). Background The OSS and the CS are commonly used to assess shoulder outcomes. However, few studies have evaluated the measurement properties of the OSS and CS in terms of responsiveness and minimal clinically important change. Methods The study included 126 patients who reported having difficulty returning to usual activities 8 to 12 weeks after arthroscopic decompression surgery for subacromial impingement syndrome. The assessment at baseline and at 3 months included the OSS, the CS, and the European Quality of Life-5 Dimensions-3 Level (EQ-5D-3L) index. Responsiveness was assessed as follows: by correlation analysis between the change scores of the OSS, CS, and EQ-5D-3L index, and the Patient Global Impression of Change (PGIC) scale; by receiver-operating-characteristic (ROC) curve analysis using the PGIC scale as an external anchor; and by effect-size statistics. Results At 3 months, a follow-up assessment of 112 patients (89%) was conducted. The change scores of the CS and the OSS were more strongly correlated with the external anchor (PGIC scale) than the change score of the EQ-5D-3L index. The areas under the ROC curves exceeded 0.80 for both shoulder scores, with no significant differences between them, and comparable effect-size estimates were observed for the CS and the OSS. Minimal clinically important change ROC values were 6 points for the OSS and 11 points for the CS, with upper 95% cutoff limits of 12 and 22 points, respectively. Conclusion The CS and the OSS were both suitable for assessing improvement after decompression surgery.

Clinical course and prognosis of musculoskeletal pain in patients referred for physiotherapy: does pain site matter?

BMC Musculoskeletal Disorders (2017)

Nils-Bo de Vos Andersen Peter Kent Jakob Hjort David Høyrup Christiansen

Danish patients with musculoskeletal disorders are commonly referred for primary care physiotherapy treatment but little is known about their general health status, pain diagnoses, clinical course and prognosis. The objectives of this study were to 1) describe the clinical course of patients with musculoskeletal disorders referred to physiotherapy, 2) identify predictors associated with a satisfactory outcome, and 3) determine the influence of the primary pain site diagnosis relative to those predictors. This was a prospective cohort study of patients (n = 2,706) newly referred because of musculoskeletal pain to 30 physiotherapy practices from January 2012 to May 2012. Data were collected via a web-based questionnaire 1–2 days prior to the first physiotherapy consultation and at 6 weeks, 3 and 6 months, from clinical records (including primary musculoskeletal symptom diagnosis based on the ICPC-2 classification system), and from national registry data. The main outcome was the Patient Acceptable Symptom State. Potential predictors were analysed using backwards step-wise selection during longitudinal Generalised Estimating Equation regression modelling. To assess the influence of pain site on these associations, primary pain site diagnosis was added to the model. Of the patients included, 66% were female and the mean age was 48 (SD 15). The percentage of patients reporting their symptoms as acceptable was 32% at 6 weeks, 43% at 3 months and 52% at 6 months. A higher probability of satisfactory outcome was associated with place of residence, being retired, no compensation claim, less frequent pain, shorter duration of pain, lower levels of disability and fear avoidance, better mental health and being a non-smoker. Primary pain site diagnosis had little influence on these associations, and was not predictive of a satisfactory outcome. Only half of the patients rated their symptoms as acceptable at 6 months. Although satisfactory outcome was difficult to predict at an individual patient level, there were a number of prognostic factors that were associated with this outcome. These factors should be considered when developing generic prediction tools to assess the probability of satisfactory outcome in musculoskeletal physiotherapy patients, because the site of pain did not affect that prognostic association.

Effectiveness of a 24-hour access outpatient clinic for patients with chronic conditions in hospital outpatient follow-up: a registry-based controlled cohort study of healthcare utilisation and mortality

Integrated Healthcare Journal (2022)

Anders Damgaard Møller Schlünsen David Høyrup Christiansen Ulrich Fredberg Peter Vedsted

Objective

To evaluate the effectiveness of a 24-hour telephone access outpatient clinic (24-hour access clinic) in terms of healthcare utilisation and mortality in patients with five chronic conditions (chronic obstructive pulmonary disease, atrial fibrillation/flutter, congestive heart failure, inflammatory bowel disease and chronic liver disease).

Methods and analysis

This was a registry-based controlled cohort study. The 24-hour access clinic was established at Silkeborg Regional Hospital in Central Denmark Region. The five other regional hospitals served as comparison hospitals. The 24-hour access clinic allowed patients with five chronic conditions with ongoing hospital outpatient follow-up to call the hospital outpatient clinic in case of an exacerbation. Outcomes were use of hospital admissions, length of stay (LOS), outpatient visits, contacts to general practice and all-cause mortality during 18 months of follow-up.

Results

The study included 992 the 24-hour access patients and 3878 usual care patients. For the five conditions combined, the 24 hours access patients had fewer all-cause admissions (incidence rate ratio (IRR) 0.81, 95% Cl 0.71 to 0.92), general practice out-of-hours contacts (IRR 0.81, 95% C 0.71 to .92) and shorter LOS (IRR 0.71, 95% CI 0.57 to 0.88). The rate of all-cause outpatient visits tended to be higher (IRR 1.07, 95% CI 0.99 to 1.15). General practice daytime contacts were similar between the groups, and there was no significant difference in mortality.

Conclusions

The results suggest that a 24-hour telephone access clinic may lead to enhanced integration of care measured as unplanned acute care substituted with planned outpatient care.
