Osteoarthritis and the rule of halves

<b>Background</b> Symptomatic osteoarthritis poses a major challenge to primary health care but no studies have related accessing primary care ("detection"), receiving recommended treatments ("treatment"), and achieving adequate control ("control").<p></p> <b>Objective</b> To provide estimates of detection, treatment, and control within a single population adapting the approach used to determine a Rule of Halves for other long-term conditions.<p></p> <b>Setting</b> General population.<p></p> <b>Participants</b> 400 adults aged 50+ years with prevalent symptomatic knee osteoarthritis.<p></p> <b>Design</b> Prospective cohort with baseline questionnaire, clinical assessment, and plain radiographs, and questionnaire follow-up at 18 and 36 months and linkage to primary care medical records.<p></p> <b>Outcome measures</b> "Detection" was defined as at least one musculoskeletal knee-related GP consultation between baseline and 36 months. "Treatment" was self-reported use of at least one recommended treatment or physiotherapy/hospital specialist referral for their knee problem at all three measurement points. Pain was "controlled" if characteristic pain intensity <5 out of 10 on at least two occasions.<p></p> <b>Results</b> In 221 cases (55.3%; 95%CI: 50.4, 60.1) there was evidence that the current problem had been detected in general practice. Of those detected, 164 (74.2% (68.4, 80.0)) were receiving one or more of the recommended treatments at all three measurement points. Of those detected and treated, 45 (27.4% (20.5, 34.3)) had symptoms under control on at least two occasions. Using narrower definitions resulted in substantially lower estimates.<p></p> <b>Conclusion</b> Osteoarthritis care does not conform to a Rule of Halves. Symptom control is low among those accessing health care and receiving treatment

Insomnia in survivors 8.5 years after the Utøya Island terrorist attack: transition from late adolescence to early adulthood - the Utøya study

Background: Insomnia is a global health concern, associated with many mental and physical health conditions. Prevalence of insomnia is reported to increase during adolescence and early adulthood. High levels of insomnia are also reported in adolescents up to 2.5 years after a traumatic event. What is less well understood is the prevalence of insomnia in a trauma exposed population transitioning from adolescence to adulthood. Objective: To assess insomnia in the survivors in the 2011 Utøya Island terrorist attack, 2.5 years and 8.5 years after the attack when the majority of survivors were transitioning from late adolescence to early adulthood. Method: Participants were 336 survivors of the Utøya Island attack who completed the Utøya Study 2.5 years (T3) and 8.5 years (T4) after the attack. Participants completed a face-to-face interview including the Bergen Insomnia Scale (BIS), which was used to assess insomnia symptoms and prevalence of meeting diagnostic criteria for insomnia. Results: Insomnia was indicated in 47.7% of survivors 8.5 years after the attack. Insomnia prevalence did not significantly change from 2.5 to 8.5 years after the attack, though insomnia symptoms (BIS sum score) were found to increase. Age was negatively associated with insomnia at T4, with older age being associated with less insomnia. No significant sex difference was found in insomnia prevalence at T4. Conclusion: Almost a decade after the Utøya Island terrorist attack, nearly a half of the young survivors in our study reported insomnia and typical age- and sex-related differences in sleep were not always seen. This rate is almost double what is reported in the general population (20–30%) indicating a high level of unmet need in this population. The implications of such sleep disruption during a critical time for physical, mental, social and cognitive development are far reaching

Implementation of musculoskeletal Models of Care in primary care settings: Theory, practice, evaluation and outcomes for musculoskeletal health in high-income economies

Musculoskeletal conditions represent one of the largest causes of years lived with disability in high-income economies. These conditions are predominantly managed in primary care settings, and yet, there is a paucity of evidence on which approaches work well in increasing the uptake of best practice and in closing the evidence-to-practice gap. Increasingly, musculoskeletal models of service delivery (as components of models of care) such as integrated care, stratified care and therapist-led care have been tested in primary health care pathways for joint pain in older adults, for low back pain and for arthritis. In this chapter, we discuss why implementation of these models is important for primary care and how models are implemented using three case examples: we review implementation theory, principles and outcomes; we consider the role of health economic evaluation; and we propose key evidence gaps in this field. We propose the following research priorities for this area: investigating the generalisability of models of care across, for example, urban and rural settings, and for different musculoskeletal conditions; increasing support for self-management; understanding the importance of context in choosing a model of care; detailing how implementation has been undertaken; and evaluation of implementation and its impact

Development of a behaviour change intervention: a case study on the practical application of theory

BACKGROUND: Use of theory in implementation of complex interventions is widely recommended. A complex trial intervention, to enhance self-management support for people with osteoarthritis (OA) in primary care, needed to be implemented in the Managing Osteoarthritis in Consultations (MOSAICS) trial. One component of the trial intervention was delivery by general practitioners (GPs) of an enhanced consultation for patients with OA. The aim of our case study is to describe the systematic selection and use of theory to develop a behaviour change intervention to implement GP delivery of the enhanced consultation. METHODS: The development of the behaviour change intervention was guided by four theoretical models/frameworks: i) an implementation of change model to guide overall approach, ii) the Theoretical Domains Framework (TDF) to identify relevant determinants of change, iii) a model for the selection of behaviour change techniques to address identified determinants of behaviour change, and iv) the principles of adult learning. Methods and measures to evaluate impact of the behaviour change intervention were identified. RESULTS: The behaviour change intervention presented the GPs with a well-defined proposal for change; addressed seven of the TDF domains (e.g., knowledge, skills, motivation and goals); incorporated ten behaviour change techniques (e.g., information provision, skills rehearsal, persuasive communication); and was delivered in workshops that valued the expertise and professional values of GPs. The workshops used a mixture of interactive and didactic sessions, were facilitated by opinion leaders, and utilised 'context-bound communication skills training.' Methods and measures selected to evaluate the behaviour change intervention included: appraisal of satisfaction with workshops, GP report of intention to practise and an assessment of video-recorded consultations of GPs with patients with OA. CONCLUSIONS: A stepped approach to the development of a behaviour change intervention, with the utilisation of theoretical frameworks to identify determinants of change matched with behaviour change techniques, has enabled a systematic and theory-driven development of an intervention designed to enhance consultations by GPs for patients with OA. The success of the behaviour change intervention in practice will be evaluated in the context of the MOSAICS trial as a whole, and will inform understanding of practice level and patient outcomes in the trial

The management of osteoarthritis in general practice: development and implementation of a model consultation

Background People with osteoarthritis (OA) frequently consult general practitioners (GPs) for the problem but the care they receive in these consultations is often sub-optimal. The aim of the studies described in this thesis was to enhance GP clinical practice for OA by developing and implementing a model OA consultation for the initial contact between a GP and an older patient presenting with peripheral joint pain. Methods A consensus exercise was undertaken to develop the model OA consultation. This was followed by the development, and delivery in a series of workshops, of a behaviour change intervention to implement the model in practice. Impact of workshops was assessed by before-and-after methods on directly observed GP use of the model OA consultation in video-recorded consultations with simulated patients, and by self-report measures (at baseline, and one and five months after). Learner reactions and delivery in day-to-day practice were assessed. Results The model OA consultation consisted of 25 tasks for assessment and initial management. A four workshop series was developed and delivered to 24 GPs and included didactic, interactive and skills training (with simulated patients) sessions. The workshops addressed barriers and facilitators for change identified in the development of the behaviour change intervention. GP use of the model OA consultation, by 15 GPs whose video-recorded consultations were assessed, was enhanced after workshops compared with before, evidenced by increased use of 14 tasks from a median of 7 tasks before to 11 after. Impact on self-report measures was inconclusive. Learner reactions were positive but delivery in day-to-day practice was limited. Conclusion A before and after study has demonstrated that GP use of a model OA consultation in a simulated setting can be enhanced. Further research and quality improvement initiatives will be needed to enhance use of the model OA consultation in day-to-day practice

Sleep-related memory consolidation in the psychosis spectrum phenotype

Sleep and memory processing impairments range from mild to severe in the psychosis spectrum. Relationships between memory processing and sleep characteristics have been described for schizophrenia, including unaffected first-degree relatives, but they are less clear across other high-risk groups within the psychosis spectrum. In this study, we investigated high-risk individuals with accumulated risk-factors for psychosis and subthreshold symptoms. Out of 1898 screened individuals, 44 age- and sex-matched participants were sub-grouped into those with substantial environmental risk factors for psychosis and subthreshold psychotic symptoms (high-risk group) and those without these phenotypes (low-risk controls). Four groups (high/low risk, morning/evening training) were trained and tested in the laboratory for sustained attention, motor skill memory (finger-tapping task) and declarative memory (word-pair learning task) immediately after training, again after a night of EEG-recorded sleep at home or a period of daytime wakefulness, and again after 24 h from training. No differences in sustained attention or in memory consolidation of declarative and motor skill memory were found between groups for any time period tested. However, a group difference was found for rapid-eye movement (REM) sleep in relation to motor skill memory: the longer the total sleep time, particularly longer REM sleep, the greater the performance gain, which occurred only in high-risk individuals. In conclusion, our results suggest a gain in motor skill performance with sufficient sleep opportunity for longer REM sleep in high-risk individuals with subthreshold psychotic symptoms. Declarative memory did not benefit from sleep consolidation above or beyond that of the control group
