Development of a tool to support general practitioners to help adolescents with knee pain: an analysis using the Theoretical Domains Framework.

AIM: Using the Theoretical Domains Framework (TDF) and COM-B model, this study aimed to determine the facilitators to a support tool for adolescent non-traumatic knee pain in general practice. BACKGROUND: Many children and adolescents with non-traumatic knee pain consult their general practice. Currently, there are no tools to support general practitioners in the diagnosis and management of this group. There is a need to identify behavioural targets that would facilitate further development and implementation of such a tool. METHODS: This study was designed as a qualitative study using focus group interviews with 12 medical doctors working in general practice. The semi-structured focus group interviews conducted online and followed an interview guide based on the TDF and COM-B model. Data were analysed via thematic text analysis. FINDINGS: One of the biggest challenges from the general practitioner's perspective was how to manage and guide adolescents with non-traumatic knee pain. The doctors had doubts in their capability to diagnose knee pain and saw opportunity to help structure the consultation. The doctors felt motivated to use a tool but considered access a potential barrier. Increasing opportunity and motivation by creating access in the community among general practitioners was considered important. We identified several barriers and facilitators for a support tool for the management of adolescent non-traumatic knee pain in general practice. To align with user needs, future tools should support diagnostic workup, structure the consultation and be easily available among doctors working in general practice.

Pain medication use for musculoskeletal pain among children and adolescents: a systematic review.

OBJECTIVES: Musculoskeletal pain is common among children and adolescents. Despite the lack of evidence regarding harms and benefits, musculoskeletal pain is often managed with pain medication. The aim of this systematic review is to assess the prevalence of pain medication use for musculoskeletal pain among children and adolescents and the factors and side effects associated with use. CONTENT: Three databases (EMBASE, CINAHL and PsychINFO) were systematically searched to identify studies designed to examine the prevalence, frequency or factors associated with the use of pain medication for musculoskeletal pain in children and adolescents (aged 6-19 years). The included studies were assessed for study quality and data were extracted. SUMMARY: The search initially provided 20,135 studies. After screening titles, abstracts and full-texts, 20 studies were included. In school settings, 8-42% of children used pain medication for musculoskeletal pain, and 67-75% of children in sports clubs and from pain clinics used pain medication. The most consistent factors associated with the use of pain medications were pain characteristics and psychological factors (e.g. being bullied, low-self-esteem), while mixed evidence was found for increasing age and female gender. Only two studies reported on the duration of use and only one study on adverse effects related to the use of pain medication. OUTLOOK: We found that 8-42% of adolescents from school-based samples use pain medication for MSK pain, while the prevalence among adolescents from sports clubs and pain clinics is higher (67-75%). Pain characteristics (pain duration, severity, intensity, disability levels and the presence of ≥2 pain conditions or multisite pain) and psychological factors were associated with a higher use of pain medication, while for higher age and female gender the evidence of association was mixed. Future studies should systematically collect information on the type, duration of use of pain medication and side effects to confirm the findings of this review.

Development and validation of the Sorting non-trauMatIc adoLescent knEe pain (SMILE) tool - a development and initial validation study.

BACKGROUND: Despite the commonality of adolescent knee pain, there are no tools to support medical doctors to correctly diagnose knee pain. This study aimed to develop and evaluate a support tool for diagnosing the most common types of non-traumatic adolescent knee pain. METHOD: A systematic search on Medline identified the literature on clinical tests and diagnoses of adolescent knee pain. The search was supplemented by textbooks and transformed into a diagnostic flowchart based on onset, symptoms, and pain localisation. This tool was revised based on feedback from general practitioners and experts in sports medicine. The tool was evaluated on two separate days with blinded assessors. Overall, 27 participants (aged 10-17 years) with non-traumatic knee pain were included. All participants were diagnosed by medical doctors or medical students, without and with the use of the tool. Diagnoses were compared to a gold standard (expert clinician). An interview to inform optimisations of the tool was performed with the assessors. Percentage agreement with the gold standard, and Kappa statistic for interrater reliability were calculated. RESULTS: The final tool improved diagnostic agreement with the gold standard from 22.7% (95% CI 10.3-35.1) to 77.3% (95% CI 64.9-89.7). Inter-rater reliability increased from poor agreement k = - 0.04 (95% CI, - 0.12-0.04) to moderate agreement k = 0.56 (95% CI, 0.40-0.72). CONCLUSION: This simple diagnostic tool is quick to use and may assist doctors in diagnosing non-traumatic knee pain in adolescents.

Translation, validity and reliability of the Danish version of the Adolescent Insomnia Questionnaire.

Background: The Adolescent Insomnia Questionnaire (AIQ), English version, is the only validated screening measure developed specifically to identify insomnia symptoms in adolescents. To date, no specific screening tool for adolescent insomnia is present in Danish language. The aim of this study was to translate and validate the AIQ in a sample of Danish adolescents. Methods: The AIQ underwent a process of forward-backward translation and pilot testing. Subsequently, data were collected at baseline and two-week follow-up from adolescents aged 11-19, who completed both the AIQ and an available adult measure of insomnia (the Athens Insomnia Scale, AIS). The internal consistency, test-retest reliability and convergent validity were assessed. Exploratory factor analysis was conducted to identify the latent factors underlying the questionnaire. Results: At baseline 185 adolescents (18% males and 82% females, mean age 16.0 years) and 102 (55.1%) at two-week follow-up completed the questionnaires. The AIQ showed excellent internal consistency for the total score (Cronbach's a: 0.88) and good convergent validity with the AIS total score (Pearson's correlation value= 0.86, P<0.001). The test-retest reliability at two weeks was very satisfactory (ICC coefficient = 0.89; 95% CI 0.84, 0.92). Results from the exploratory factor analysis identified a three-model solution corresponding to the same three-model solution identified within the original development sample. Conclusions: The Danish version of the AIQ demonstrated satisfactory psychometric properties in terms of internal consistency, test-retest reliability and validity, which supports its use as a screening tool for the identification of insomnia symptoms in adolescents, including Danish-speaking adolescents.

Long-term Prognosis and Impact of Osgood-Schlatter Disease 4 Years After Diagnosis: A Retrospective Study.

BACKGROUND: Knee pain is common during adolescence, with Osgood-Schlatter disease (OSD) being the most frequent condition. Despite this, research regarding the long-term prognosis of OSD is limited. PURPOSE: To evaluate the prognosis 2 to 6 years after the diagnosis of OSD. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This retrospective cohort study included patients diagnosed with OSD at a single orthopaedic department between 2010 and 2016. Patients were contacted in 2018 and asked to complete a self-reported questionnaire regarding knee pain, knee function (Knee injury and Osteoarthritis Outcome Score [KOOS] Sports/Recreation subscale), Health-related quality of life (HRQoL) (youth version of EuroQol 5 dimensions 3 levels [EQ-5D-3L-Y]), and physical activity. RESULTS: Out of 84 patients, 43 responded. Of these, 60.5% (n = 26) reported OSD-related knee pain at follow-up (median follow-up, 3.75 years). The median symptom duration was 90 months (interquartile range, 24-150 months) for those still experiencing knee pain, and 42.9% of these reported daily knee pain. Fifty-four percent with knee pain had reduced their sports participation compared with 35.3% of those without knee pain. KOOS Sports/Recreation subscale scores were significantly lower in those with knee pain compared with those without knee pain (53 [95% CI, 42-63] vs 85 [95% CI, 76-94], respectively). Participants with knee pain reported lower HRQoL (0.71 [95% CI, 0.57-0.84]) compared with those without knee pain (0.99 [95% CI, 0.97-1.00]). CONCLUSION: This study indicates that OSD may not always be self-limiting. The lower self-reported function and HRQoL in those with continued pain may be a consequence of impaired physical activity due to knee pain.
