Suspect and non-target screening of semi-volatile emerging contaminants in indoor dust from Danish kindergartens.

Indoor dust is a sink of hundreds of organic chemicals, and humans may potentially be exposed to these via indoor activities. This study investigated potentially harmful semi-volatile organic contaminants in indoor dust from Danish kindergartens using suspect and non-target screening on gas chromatography (GC)-Orbitrap, supported by target analyses using GC-low resolution mass spectrometry (LRMS). A suspect list of 41 chemicals with one or more toxicological endpoints, i.e. endocrine disruption, carcinogenicity, neurotoxicity and allergenicity, known or suspected to be present in indoor dust, was established including phthalate and non-phthalate plasticizers, flame retardants, bisphenols, biocides, UV filters and other plastic additives. Of these, 29 contaminants were detected in the indoor dust samples, also including several compounds that had been banned or restricted for years. In addition, 22 chemicals were tentatively identified via non-target screening. Several chemicals have not previously been detected in Danish indoor dust. Most of the detected chemicals are known to be potentially harmful for human health while hazard assessment of the remaining compounds indicated limited risks to human. However, children were not specifically considered in this hazard assessment.

Prognostic factors of knee pain and function 12 months after total knee arthroplasty: A prospective cohort study of 798 patients.

BACKGROUND: Approximately 20% of patients undergoing total knee arthroplasty (TKA) do not experience long-term improvements. Our aim was to identify prognostic factors of knee pain and function 12 months after TKA. METHODS: In a prospective cohort study, 1026 patients underwent primary TKA between 2018 and 2020. Main outcome was measured by the Oxford Knee Score (OKS) categorized in five categories (0-9, 10-19, 20-29, 30-39 and 40-48). Potential prognostic factors obtained at baseline included sex, age, baseline OKS, pain catastrophizing scale, EuroQol 5 dimensions, previous surgery, BMI, ASA classification, opioid consumption, living and employment conditions as well as educational level. Ordinal logistic regression analysis was used to identify prognostic factors of OKS. RESULTS: A total of 915 patients completed follow up (89%), and patients with complete data were included (n = 798). Patients with a baseline OKS between 10-19 and 20-29 had 2.5 (CI 1.6;4.0) and 1.6 (CI 1.1;2.4) higher odds, respectively, of no improvement or deterioration to a lower post-operative OKS category, compared with patients with a baseline score between 30 and 39. Female patients had 1.5 (CI 1.1;2.0) and patients receiving social benefits compared with retired patients had 2.0 (CI 1.1;3.5) higher odds of no improvement or deterioration to a lower OKS category. CONCLUSION: Baseline level of pain and function, sex and employment status were significant prognostic factors of OKS 12 months after TKA. Overall, the regression analysis only explained 4% of the outcome, indicating that it is difficult to predict 12-month TKA outcome prior to surgery.

Patient and public involvement to inform the protocol of a clinical trial comparing total hip arthroplasty with exercise: an exploratory qualitative case study.

OBJECTIVE: To explore patient, clinician and decision-maker perceptions on a clinical trial evaluating the effectiveness of total hip arthroplasty (THA) compared with exercise to inform the trial protocol. DESIGN: This is an exploratory qualitative case study using a constructivist paradigm. SETTING AND PARTICIPANTS: Participants were enrolled into three key stakeholder groups: patients eligible for THA, clinicians, and decision makers. Focus group interviews were conducted in undisturbed conference rooms at two hospitals in Denmark, according to group status using semi-structured interview guides. ANALYSIS: Interviews were recorded, transcribed verbatim and thematic analysed using an inductive approach. RESULTS: We conducted 4 focus group interviews with 14 patients, 1 focus group interview with 4 clinicians (2 orthopaedic surgeons and 2 physiotherapists) and 1 focus group interview with 4 decision-makers. Two main themes were generated. 'Treatment expectations and beliefs impact management choices' covered three supporting codes: Treatment without surgery is unlikely to lead to recovery; Clinician authority impacts the management narrative; The 'surgery vs exercise' debate. 'Factors influencing clinical trial integrity and feasibility' highlighted three supporting codes: Who is considered eligible for surgery?; Facilitators and barriers for surgery and exercise in a clinical trial context; Improvements in hip pain and hip function are the most important outcomes. CONCLUSIONS: Based on key stakeholder treatment expectations and beliefs, we implemented three main strategies to improve the methodological rigorousness of our trial protocol. First, we added an observational study investigating the generalisability to address a potential low enrolment rate. Second, we developed an enrolment procedure using generic guidance and balanced narrative conveyed by an independent clinician to facilitate communication of clinical equipoise. Third, we adopted change in hip pain and function as the primary outcome. These findings highlight the value of patient and public involvement in the development of trial protocols to reduce bias in comparative clinical trials evaluating surgical and non-surgical management. TRIAL REGISTRATION NUMBER: NCT04070027 (pre-results).

Hip precautions after posterior-approach total hip arthroplasty among patients with primary hip osteoarthritis do not influence early recovery: a systematic review and meta-analysis of randomized and non-randomized studies with 8,835 patients.

BACKGROUND AND PURPOSE: Hip precautions are routinely prescribed to patients with osteoarthritis to decrease dislocation rates after total hip arthroplasty (THA) using a posterior approach. However, recommendations have been based on very low certainty of evidence. We updated the evidence on the influence of hip precautions on early recovery following THA by this systematic review. MATERIALS AND METHODS: We performed systematic searches for randomized controlled trials (RCT) and non-randomized (NRS) studies in MEDLINE, Embase, PEDro, and CINAHL published from 2016 to July 2022. 2 reviewers independently included studies comparing postoperative precautions with minimal or no precautions, extracted data, and assessed the risk of bias. Random effects meta-analyses were used to synthesize the results. The certainty of the evidence was rated by the Grading of Recommendations Assessment and Evaluation approach. The critical outcome was the risk of hip dislocations within 3 months of surgery. Other outcomes were long-term risk of dislocation and reoperation, self-reported and performance-based assessment of function, quality of life, pain, and time to return to work. RESULTS: 4 RCTs and 5 NRSs, including 8,835 participants, were included. There may be no or negligible difference in early hip dislocations (RCTs: risk ratio [RR] 1.8, 95% confidence interval [CI] 0.6-5.2; NRS: RR 0.9, CI 0.3-2.5). Certainty in the evidence was low for RCTs and very low for NRSs. Finally, precautions may reduce the performance-based assessment of function slightly, but the evidence was very uncertain. For all other outcomes, no differences were found (moderate to very low certainty evidence). CONCLUSION: The current evidence does not support routinely prescribing hip precautions post-surgically for patients undergoing THA to prevent hip dislocations. However, the results might change with high-quality studies.

Increased shoulder pain across an exercise session and subsequent shoulder exercise: a prospective cohort study.

BACKGROUND: Shoulder complaints are common and the recommended first-line treatment is exercise therapy. However, it remains unknown if increased shoulder pain after an exercise session is a barrier for subsequent exercise dose, particularly in people with high fear-avoidance beliefs. Such knowledge could indicate ways to optimise shoulder rehabilitation. The aim was to examine whether increased shoulder pain across an exercise session was associated with a lower subsequent exercise dose, and if high fear-avoidance beliefs exaggerated this association. METHODS: We conducted a prospective cohort study using data from a randomised controlled trial in Central Denmark Region 2017-2019. Participants were employees (n = 79) with shoulder complaints and high occupational shoulder exposures. The intervention was a home-based or partly supervised exercise programme lasting 2-3 months. Linear mixed models were used to examine the associations between change in shoulder pain and exercise dose (number of repetitions, progression level (1-3), resistance level (1-3), and time until next exercise session [days]). RESULTS: At baseline, the participants had a median pain intensity at rest of 2 on a numerical rating scale (0-10). For a 1-cm increase in pain on a visual analogue scale (0-10 cm) during an exercise session, the subsequent number of repetitions, progression level and resistance level were - 1.3 (95% confidence interval [CI] - 3.4 to 0.9), 0.0 (95% CI - 0.1 to 0.0) and - 0.0 (95% CI - 0.1 to 0.0), respectively. Likewise, the time until next exercise session was - 0.6 (95% CI - 2.4 to 1.3) days for a 1-cm increase. There were no interactions with fear-avoidance beliefs. CONCLUSION: Increased pain across an exercise session was not associated with subsequent exercise dose, regardless of fear-avoidance beliefs, among employees with shoulder complaints and high occupational shoulder exposures. TRIAL REGISTRATION: The trial was registered at Clinicaltrials.gov 19/05/2017 (ID: NCT03159910).

Feasibility, safety, and patient-reported outcomes 90 days after same-day total knee arthroplasty: a matched cohort study.

BACKGROUND AND PURPOSE: Despite increased attention to and acceptance of fast-track procedures, there is a lack of studies concerning discharge on the day of surgery (DOS) following total knee arthroplasty (SD-TKA). We evaluated the feasibility of SD-TKA, and compared safety and patient-reported outcomes (PROs) between patients undergoing SD-TKA and patients undergoing standard TKA. PATIENTS AND METHODS: A SD-TKA group (n = 101) was matched 1:1 to a standard TKA group (n = 101) on age, sex, and ASA score. Feasibility (being discharged on DOS), safety (unplanned contacts and complications evaluated by telephone calls (2 weeks), outpatient visits (2 weeks), and readmission (90 days)) were assessed. Further, Oxford Knee Score (OKS) and Visual Analogue Scale (VAS) (pain at rest and activity) were reported (90 days). RESULTS: 89 of 101 SD-TKA patients were discharged on DOS. The number of telephone calls (≤ 83) and outpatient visits (12) were similar in the 2 groups. The number of readmissions was ≤ 3 in both groups, and only 1 of the readmissions was related to TKA surgery. No differences were found at 90-day follow-up in terms of OKS (34 in both groups) or VAS (rest: SD-TKA = 7 and standard TKA = 8; activity: SD-TKA = 17 and standard TKA = 15). INTERPRETATION: SD-TKA is feasible in a selected group of patients, and safety and PROs are comparable to patients undergoing standard TKA.

High Patient Satisfaction with Examination by Advanced Practice Physiotherapists in an Orthopaedic Outpatient Shoulder Clinic: A Cross-Sectional Study Using Quantitative and Qualitative Methods.

Purpose: To evaluate patients' satisfaction with being examined and diagnosed in an orthopaedic outpatient shoulder clinic, determine whether a difference exists between levels of satisfaction among patients examined by advanced practice physiotherapists (APPs) and orthopaedic surgeons (OSs), and explore patients' experiences with being examined by APPs. Method: One hundred and thirty-three patients participated in a cross-sectional questionnaire study using the Visit-Specific Satisfaction Instrument (VSQ-9). Primary outcome was satisfaction with "The visit overall" (item 9). Nine patients participated in semi-structured interviews, which were thematically analyzed. Results:There was no significant difference in satisfaction with "The visit overall" between patients examined by an OS (median: 75, 1st-3rd quartiles: 75-100) and an APP (median: 100, 1st-3rd quartiles: 75-100). The VSQ-9 total score was not significantly different between groups, but some items regarding direct interaction with the health provider were scored significantly higher in the APP group. Patients were particularly satisfied with APPs' ability to explain during the consultation. Conclusions: The results showed high levels of satisfaction with examinations performed by both OSs and APPs with no difference between groups concerning "The visit overall." From a patient perspective, the results support the use of APPs to examine and diagnose selected patients in an orthopaedic outpatient shoulder clinic.

Objectif : évaluer la satisfaction des patients après un examen et un diagnostic dans une clinique orthopédique ambulatoire de l'épaule, déterminer s'il y a une différence entre les taux de satisfaction chez les patients examinés par des physiothérapeutes en pratique avancée (PPA) et les chirurgiens orthopédiques (CO) et explorer les expériences des patients examinées par des PPA. Méthodologie : au total, 133 patients ont participé à un questionnaire transversal faisant appel à l'instrument de satisfaction lors de la visite (VSQ-9). Le résultat primaire était la satisfaction à l'égard de « l'ensemble de la visite ¼ (point 9). Neuf patients ont participé à des entrevues semi-structurées, analysées par thème. Résultats : il n'y avait pas de différence significative sur le plan de la satisfaction à l'égard de « l'ensemble de la visite ¼ entre les patients examinés par un CO (médiane : 75, premier au troisième quartiles : 75 à 100) et un PPA (médiane : 100, premier au troisième quartiles :75 à 100). Le score total du VSQ-9 n'était pas significativement différent entre les groupes, mais certains points relatifs à l'interaction directe avec le professionnel de la santé obtenaient un pointage beaucoup plus élevé dans le groupe des PPA. Les patients étaient particulièrement satisfaits par la capacité des PPA à donner des explications pendant la consultation. Conclusions : les résultats ont démontré un taux élevé de satisfaction à l'égard des examens effectués à la fois par des CO et des PPA, sans différence entre les groupes au sujet de « l'ensemble de la visite ¼. De l'avis des patients, les résultats soutiennent le recours au PPA pour examiner et diagnostiquer certains patients dans une clinique orthopédique ambulatoire de l'épaule.

Total hip arthroplasty versus progressive resistance training in patients with severe hip osteoarthritis: protocol for a multicentre, parallel-group, randomised controlled superiority trial.

INTRODUCTION: Hip osteoarthritis (OA) is the leading cause for total hip arthroplasty (THA). Although, being considered as the surgery of the century up to 23% of the patients report long-term pain, and deficits in physical function and muscle strength may persist after THA. Progressive resistance training (PRT) appears to improve multiple outcomes moderately in patients with hip OA. Current treatment selection is based on low-level evidence as no randomised controlled trials have compared THA to non-surgical treatment. The primary aim of this trial is to investigate whether THA followed by standard care is superior to 12 weeks of supervised PRT followed by 12 weeks of optional unsupervised PRT for improving hip pain and function in patients with severe hip OA. METHODS AND ANALYSIS: This is a protocol for a multicentre, parallel-group, assessor-blinded, randomised controlled superiority trial conducted at four hospitals across three healthcare regions in Denmark. 120 patients aged ≥50 years with clinical and radiographic hip OA found eligible for THA by an orthopaedic surgeon will be randomised to THA followed by standard care, or 12 weeks of PRT (allocation 1:1). The primary outcome will be change in patient-reported hip pain and function, measured using the Oxford Hip Score, from baseline to 6 months after initiating the treatment. Key secondary outcomes will be change in the Hip disability and Osteoarthritis Outcome Score subscales, University of California Los Angeles Activity Score, 40 m fast-paced walk test, 30 s chair stand test and occurrence of serious adverse events. Patients declining participation in the trial will be invited into a prospective observational cohort study. ETHICS AND DISSEMINATION: The trial has been approved by The Regional Committees on Health Research Ethics for Southern Denmark (Project-ID: S-20180158). All results will be presented in peer-reviewed scientific journals and international conferences. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov (NCT04070027).

The translated Danish version of the Western Ontario Meniscal Evaluation Tool (WOMET) is reliable and responsive.

PURPOSE: The purpose of this study was to translate and cross-culturally adapt the Western Ontario Meniscal Evaluation Tool (WOMET) for use in Denmark and evaluate its test-retest reliability and comparative responsiveness. METHODS: Sixty patients (mean age 50 years (range 19-71 years), females 57%) with meniscal injury scheduled for arthroscopic meniscal surgery at a small Danish hospital in the period from September 2017 to February 2018 were included in this study. The WOMET was translated into Danish using forward and backward translation. The WOMET was completed at baseline (pre-surgery), at 3 and 6 months postoperatively. Additionally, reliability was assessed at 3 months and 3 months plus 1 week, for patients with a stable symptom state (global response question) between test and retest. Comparative responsiveness was assessed between the WOMET and the Knee Injury and Osteoarthritis Outcome Score (KOOS4-aggregate score of 4 of the 5 KOOS subscales). RESULTS: The Danish version of WOMET showed excellent test-retest reliability, intraclass correlation coefficient of 0.88 (95% CI 0.84-0.92) for the total score. The standard error of measurement was 125 points and the minimal detectable change was 347 points (i.e. 8% and 22% of the total score, respectively). The WOMET was responsive with an effect size (ES) of 1.12 at 6 months after surgery, which was comparable to the KOOS4 (ES 1.10). CONCLUSION: The Danish version of the WOMET is a reliable and responsive measure of health-related quality of life in patients with meniscal pathology. LEVEL OF EVIDENCE: Level II.

Inter-professional agreement and collaboration between extended scope physiotherapists and orthopaedic surgeons in an orthopaedic outpatient shoulder clinic - a mixed methods study.

BACKGROUND: Extended scope physiotherapists (ESP) are increasingly supplementing orthopaedic surgeons (OS) in diagnosing patients with musculoskeletal disorders. Studies have reported satisfactory diagnostic and treatment agreement between ESPs and OSs, but methodological study quality is generally low, and only few studies have evaluated inter-professional collaboration. Our aims were: 1) to evaluate agreement on diagnosis and treatment plan between ESPs and OSs examining patients with shoulder disorders, 2) to explore and evaluate their inter-professional collaboration. METHODS: 1) In an orthopaedic outpatient shoulder clinic, 69 patients were examined independently twice on the same day by an ESP and an OS in random order. Primary and secondary diagnoses (nine categories) and treatment plan (five categories, combinations allowed) were registered by each professional and compared. Percentage of agreement and kappa-values were calculated. 2) Two semi-structured focus-group interviews were performed with ESPs and OSs, respectively. Interviews were based on the theoretical concept of Relational Coordination, encompassing seven dimensions of communication and relationship among professionals. A thematic analysis was conducted. RESULTS: 1) Agreement on primary diagnosis was 62% (95% CI: [50; 73]). ESPs and OSs agreed on the combination of diagnoses in 79% (95% CI: [70; 89]) of the cases. Partial diagnostic agreement (one professional's primary diagnosis was also registered as either primary or secondary diagnosis by the other) was 96% (95% CI: [91; 100]). Across treatment categories, agreement varied between 68% (95% CI: [57; 79]) and 100%. In 43% (95% CI: [31; 54]) of the cases, ESP and OS had full concordance between treatment categories chosen, while they agreed on at least one recommendation in 96% (95% CI: [91; 100]). 2) Positive statements of all dimensions of relational coordination were found. Three themes especially important in the inter-professional collaboration emerged: Close communication, equal and respectful relationship and professional skills. CONCLUSIONS: In the majority of cases, the ESP and OS registered the same or partly the same diagnosis and treatment plan. Indications of a high relational coordination implying a good inter-professional collaboration were found. Our results support that ESPs and OSs can share the task of examining selected patients with shoulder disorders in an orthopaedic clinic.

Patient perspectives on home-based rehabilitation exercise and general physical activity after total hip arthroplasty: A qualitative study (PHETHAS-2).

Background: Home-based rehabilitation exercise following Total Hip Arthroplasty (THA) shows similar outcomes compared to supervised outpatient rehabilitation exercise. Little is known about patients' experiences with home-based rehabilitation, and this study aimed to investigate how patients perceived home-based rehabilitation exercise and general physical activity after THA, focusing on facilitators and barriers. Methods: Semi-structured interviews of qualitative design were conducted with 22 patients who had undergone THA and who had performed home-based rehabilitation exercise. The study took place in a regional hospital in Denmark between January 2018 and May 2019. Data were analyzed using an interpretive thematic analysis approach, with theoretical underpinning from the concept 'conduct of everyday life'. The study is embedded within the Pragmatic Home-Based Exercise Therapy after Total Hip Arthroplasty-Silkeborg trial (PHETHAS-1). Results: The main theme, 'wishing to return to the well-known everyday life', and four subthemes were identified. Generally, participants found the home-based rehabilitation exercise boring but were motivated by the goal of returning to their well-known everyday life and performing their usual general physical activities, though some lacked contact to physiotherapist. Participants enrolled in the PHETHAS-1 study used the enrollment as part of their motivation for doing the exercises.  Both pain and the absence of pain were identified as barriers for doing home-based rehabilitation exercise. Pain could cause insecurity about possible medical complications, while the absence of pain could lead to the rehabilitation exercise being perceived as pointless. Conclusions: The overall goal of returning to the well-known everyday life served as a facilitator for undertaking home-based rehabilitation exercise after THA along with the flexibility regarding time and place for performing exercises. Boring exercises as well as both pain and no pain were identified as barriers to the performance of home-based rehabilitation exercise. Participants were motivated towards performing general physical activities which were part of their everyday life.

Effectiveness of supervised resistance training for patients with hip osteoarthritis - a systematic review.

INTRODUCTION: The overall effectiveness of supervised progressive resistance training among patients with hip osteoarthritis is only scarcely investigated. The objective of this study was to estimate the effectiveness of supervised progressive resistance training compared with common treatment for patients with hip osteoarthritis, focusing on patient-reported function, pain, health-related quality of life, performance-based function at end of treatment and patient-reported function at 6-12 months. METHODS: This was a systematic review and meta-analysis. A systematic search was performed on 30 January 2019 in eight electronic databases (Medline, Embase, Cochrane, Pedro, AMED, Scopus, SPORTDiscus and Cinahl). The methodology of the included studies and the overall quality of evidence was assessed using the Cochrane Risk of Bias tool and the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: A total of 189 participants with hip osteoarthritis > 50 years of age were included in the three studies. A significant difference in favour of the supervised progressive resistance groups was found in patient-reported function (weighted mean difference (MD) = 9.13 (95% confidence interval (CI): 4.45-13.80)), hip-related pain (weighted MD = 7.83 (95% CI: 2.64-13.02)) and health-related quality of life (weighted MD = 6.80 (95% CI: 1.96-11.63)) at end of treatment. The overall quality of evidence was downgraded to low due to a lack of blinding in the included studies and due to imprecision. CONCLUSIONS: Supervised progressive resistance training might be of clinical relevance for patients with hip osteoarthritis and was effective in improving patient-reported function, hip-related pain and health-related quality of life. The level of evidence is low and future studies may therefore affect the findings reported herein.

Adherence to key domains in low back pain guidelines: A cross-sectional study of Danish physiotherapists.

OBJECTIVE: The aim of the study was threefold: Firstly, to investigate the adherence to clinical practice guidelines for low back pain (LBP) among Danish physiotherapists with regard to three key domains: (a) activity, (b) work and (c) psychosocial risk factors. Secondly, to investigate whether adherence differed between physiotherapists working in private clinics (private physiotherapists) and physiotherapists working at public healthcare centres (public physiotherapists). Thirdly, to describe the physiotherapists' treatment modalities for patients with LBP. METHODS: A cross-sectional online survey was conducted with 817 physiotherapists working in the Central Denmark Region. Adherence to the guideline domains was assessed using two vignettes. The difference in adherence between the groups was assessed using the Chi-squared test. Treatment modalities were reported using descriptive statistics. RESULTS: A total of 234 physiotherapists responded, hereof 163 private physiotherapists and 71 public physiotherapists (response rate 29%). The proportions of physiotherapists managing the patients strictly in line with the guideline domains were 32% (activity), 16% (work) and 82% (psychosocial risk factors) for Vignette 1 and 6% (activity), 53% (work) and 60% (psychosocial risk factors) for Vignette 2. Public physiotherapists were more likely to manage patients strictly in line with guidelines for assessing the psychosocial risk factors compared to private physiotherapist (Vignette 1: 92% vs. 77% p = .030; Vignette 2:70% vs. 55% p = .035). Regarding the other two domains, there was no significant difference between the two groups in terms of adherence (p > .05). Concerning treatment modalities, the majority of physiotherapists instructed the patients in adopting an exercise program or informed the patients about the benign nature and prognosis of LBP. CONCLUSION: Overall, the participating Danish physiotherapists strictly adhered to only one out of three key domains. This underlines the importance of bringing focus on implementing the current guidelines' recommendations in clinical practice.

A retrospective study of 251 patients admitted to a multidisciplinary, neurorehabilitation unit with intensive care unit capabilities.

Introduction: In Denmark, specialised neurorehabilitation is centralised in two centres; one is Hammel Neurocentre. The neurointensive stepdown unit at Silkeborg Regional Hospital offers intensive care in addition to specialised neurorehabilitation of patients transferring to Hammel. Knowledge on patient's characteristics and course of rehabilitation in this kind of setting is sparse.Objective: To characterise the patients, their change in function and to identify variables associated with referral time to Hammel.Methods: Functional scores and available covariates were extracted from hospital records on 251 patients admitted from 01 November 2011 to 31 July 2016. Statistical methods included logistic regression and paired tests.Results: Mean (standard deviation) time from injury to admission at the neurointensive stepdown unit was 30 (22) d, medians (interquartile range) of Functional Independence Measure and Early Functional Abilities increased significantly from 18 (18, 19) to 24 (18, 44) and 37 (30, 46) to 52 (43, 70), respectively, during admission (p < 0.01). Spontaneous ventilation and Early Functional Abilities score on admission were positively associated with early referral. Obesity and anoxic brain injury were negatively associated with early referral.Conclusions: This study demonstrated functional improvement in patients in a neurointensive stepdown unit and identified variables associated with early referral. The study indicated higher sensitivity of the Early Functional Abilities score as compared to the Functional Independence Measure.Implications for rehabilitationPatients requiring prolonged intensive care services after severe acquired brain injury may require the fusion of neurorehabilitation and intensive care services to benefit maximally.There is a need for a consensus on which functional scores to use when documenting functional level and functional changes in patients with severe acquired brain injury and very low functional levels.The Early Functional Abilities score is an example of a valuable tool when assessing functional levels of patients with severe acquired brain injury and very low functional levels.

Reducing shoulder complaints in employees with high occupational shoulder exposures: study protocol for a cluster-randomised controlled study (The Shoulder-Café Study).

BACKGROUND: In Denmark, exercise therapy in combination with work modification is the first-choice treatment for persons with shoulder complaints and high occupational shoulder exposures. To obtain this treatment they must visit several healthcare providers, which makes usual care fragmented and uncoordinated. Therefore, we developed a new intervention which unifies the expertise that is needed. The main hypotheses are that a group-based Shoulder-Café intervention will more effectively reduce (1) shoulder complaints and (2) occupational shoulder exposures than an individual-based Shoulder-Guidance intervention (active control - enhanced usual care). METHODS: A cluster-randomised trial is conducted including 120 employees with high occupational shoulder exposures. Companies (clusters) are randomised to either Shoulder-Café or Shoulder-Guidance with a 1:1 allocation ratio. Participants are 18-65 years old and have an Oxford Shoulder Score (OSS) ≤ 40. Both interventions include a home-based shoulder-exercise programme, assessment of shoulder exposures by technical measurements and self-report, and general information on how to reduce shoulder exposures. The Shoulder-Café course also includes three café meetings with physiotherapist-supervised exercises, clinical shoulder evaluation, education on shoulder anatomy, workplace-orientated counselling, and an opportunity for a workplace visit by a health and safety consultant. The primary outcomes are the OSS at 6-month follow-up (hypothesis I), and the mean number of min/day with the arm elevated > 60° shortly after the end of the intervention (hypothesis II). We will use a mixed-model analysis that allows for company clustering, and data will be analysed according to the intention-to-treat principle. DISCUSSION: Persons with shoulder complaints and high occupational shoulder exposures are an obvious target group for secondary prevention efforts. We developed the Shoulder-Café to reduce shoulder complaints and shoulder exposures while unifying the expertise that is needed to evaluate and treat shoulder complaints. If the intervention is effective, it would warrant widespread implementation. TRIAL REGISTRATION: Clinicaltrials.gov, ID: NCT03159910. Registered on 18 May 2017.

Asymmetry and pelvic movements 6 months after total hip replacement Secondary analyses from a randomized controlled trial.

The aim was to investigate gait asymmetry and pelvic range of motion during walking and stair ascending after total hip replacement, and secondly to test whether these parameters were influenced by resistance training. A consecutive sample of 32 patients within a randomized controlled trial (control versus exercise group) was included. Speed, asymmetry and pelvic range of motion (walk and stair test) and leg power were measured preoperative, 10weeks and 6 months postoperative. Walking and stair ascending speed, leg power and pelvic movements (frontal plane) during walking increased to 6 months follow up (p<0.005). There were no significant changes in gait asymmetry or the remaining pelvic movements (p>0.05) and no between-group differences. Pelvic movements in the frontal plane during walking increased after surgery. No changes occurred in gait asymmetry and pelvic movements 6 months after total hip replacement while leg power and speed during walking and stair ascending increased significantly.

Pragmatic Home-Based Exercise after Total Hip Arthroplasty - Silkeborg: Protocol for a prospective cohort study (PHETHAS-1).

Introduction: Rehabilitation exercises are offered to patients after total hip arthroplasty (THA); however, the effectiveness and optimal type and dose of exercise remains unknown. The primary objective of this trial is to indicate the preliminary efficacy of home-based rehabilitation using elastic band exercise on performance-based function after THA, based on the relationship between the performed exercise dose and the change in performance-based function (gait speed) from 3 (start of intervention) to 10 weeks (end of intervention) after surgery. The secondary objective is to investigate if a dose-response relationship exists between the performed exercise dose and changes in: hip-related disability, lower-extremity functional performance, and hip muscle strength Methods: In this prospective cohort study, patients scheduled for THA will be consecutively included until 88 have completed the intervention period from 3 to 10 weeks postoperatively. Participants perform the standard rehabilitation program with elastic band exercises. Exercise dose (exposure) will be objectively quantified using a sensor attached to the elastic band. The primary outcome is gait speed measured by the 40-m fast-paced walk test. Secondary outcomes include: patient reported hip disability (Hip disability and Osteoarthritis Outcome Score (HOOS)), hip muscle strength (hand-held dynamometry) and lower extremity function (30-s chair stand test). Discussion: This trial will add knowledge concerning the relationship between performed exercise dose and post-operative outcomes after THA. The protocol paper describes the study design and methods in detail, including the statistical analysis plan.

Improving the referral pattern of patients with knee osteoarthritis to the orthopaedic surgeon: Development and evaluation of a new screening algorithm based on patient-reported data and radiographs.

INTRODUCTION: Many patients with knee osteoarthritis referred to orthopaedic surgeons are not eligible for surgery and might benefit from being examined by other healthcare professionals. The objective of this study was to develop and test a screening algorithm to define relevant referral to the OS. METHODS: Prior to clinical examination, 173 consecutive patients referred to the orthopaedic outpatient clinic completed questionnaires, and radiographic osteoarthritis severity was graded. The gold standard for relevant referral to an orthopaedic surgeon was based on actual treatment. The performance of the algorithm in predicting relevant referrals and total knee replacement (TKR) was assessed using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: Referral to an orthopaedic surgeon was considered relevant in 65% (113/173) of patients. Sensitivity, specificity, PPV and NPV for predicting relevant referral to an orthopaedic surgeon were 0.70, 0.56, 0.76 and 0.48, respectively. The corresponding estimates for predicting TKR surgery were 0.92, 0.56, 0.55 and 0.92. CONCLUSIONS: The algorithm was able to identify most patients relevant for referral to an orthopaedic surgeon, but less suitable for identifying those not relevant. The algorithm demonstrated excellent performance in predicting TKR surgery. With further development, this screening algorithm might contribute to improvement of the referral pattern in the orthopaedic outpatient clinic.

Low complication rate after same-day total hip arthroplasty: a retrospective, single-center cohort study in 116 procedures.

Background and purpose - Length of hospital stay (LOS) following total hip arthroplasty (THA) has been markedly reduced. Recently, same-day THA (SD-THA) was introduced, and previous studies have indicated satisfactory safety. However, studies are heterogeneous and only a few report results on SD-THA when using a posterolateral surgical approach. Thus, our aim was to evaluate the feasibility of and complications after SD-THA when using a posterolateral approach. Patients and methods - Consecutive patients scheduled for SD-THA between October 2015 and June 2016 were included. Eligibility criteria for SD-THA were: primary THA, motivation for same-day procedure, age > 18 years, ASA I or II, and the presence of a support person who could remain with the patient for 24 hours after surgery. A posterolateral surgical approach was used. Data were collected retrospectively from hospital records and the Danish National Patient Registry. Outcome measures were: complications during admission, LOS, causes of prolonged admission, and prevalence and causes of readmission at 90 days' follow-up. Results - 102 of 116 (88%) patients scheduled for SD-THA were discharged on the day of surgery. The remaining 14 patients were discharged the following day. Primary causes of prolonged admission were: dizziness/nausea, pain, and wound seepage. 7 patients had an estimated blood loss above 400 mL, but all were discharged as planned. No major complications occurred during admission. At follow-up, 3 patients had been readmitted due to pneumonia, wound infection, and dislocation, respectively. Interpretation - The results indicate that SD-THA performed with a posterolateral approach is feasible and can be performed with a low complication rate in a selected group of patients.

An Obturator Nerve Block does not Alleviate Postoperative Pain after Total Hip Arthroplasty: a Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: A substantial group of patients suffer from moderate to severe pain following elective total hip arthroplasty (THA). Due to the complex innervation of the hip, peripheral nerve block techniques can be challenging and are not widely used. Since the obturator nerve innervates both the anteromedial part of the joint capsule as well as intra-articular nociceptors, we hypothesized that an obturator nerve block (ONB) would decrease the opioid consumption after THA. METHODS: Sixty-two patients were randomized to receive ONB or placebo (PCB) after primary THA in spinal anesthesia. Primary outcome measure was opioid consumption during the first 12 postoperative hours. Secondary outcome measures included postoperative pain score, nausea score and ability to ambulate. RESULTS: Sixty patients were included in the analysis. Mean (SD) opioid consumption during the first 12 postoperative hours was 39.9 (22.3) mg peroral morphine equivalents (PME) in the ONB group and 40.5 (30.5) mg PME in the PCB group (p=0.93). No difference in level of pain or nausea was found between the groups. Paralysis of the hip adductor muscles in the ONB group reduced the control of the operated lower extremity compared with the PCB group (p=0.026). This did, however, not affect the subjects' ability to ambulate. CONCLUSIONS: A significant reduction in postoperative opioid consumption was not found for active versus PCB ONB after THA.
