Fear-avoidant beliefs and behaviours after upper limb fracture in older people: a systematic review and meta-ethnography.

PURPOSE: This systematic review aimed to understand older people's perspectives of associated fear-avoidant beliefs following upper limb fracture. METHODS: Published and unpublished literature databases were systematically searched from inception to 1st April 2023. Qualitative studies reporting the perspectives of fear-avoidant beliefs or behaviours in people who had sustained an upper limb fracture were eligible. Data extracted included characteristics of people interviewed, experiences and perceptions of fear, fear of falling, and fear-avoidant beliefs and behaviours. Data were synthesised using a meta-ethnography approach and the GRADE-CERQUAL tool. RESULTS: Eight studies were eligible (n = 150 participants; 109 distal radial/41 humeral fracture). Three overarching themes were identified: (1) type of fear-avoidant experiences, (2) drivers of fear-avoidant beliefs and behaviours, and (3) consequences of fear-avoidant beliefs and behaviours. The themes generated were based on moderate confidence evidence. In summary, whilst some patients initially consider upper limb fractures to be relatively minor injuries, over time, the realisation occurs that they have wide-ranging consequences with longer-term perspectives on recovery. This often occurs following an initial period of reduced fear. Providing education and support immediately post-fracture to prevent or challenge initial health beliefs around fear of falls and fear of movement is imperative to recovery. CONCLUSIONS: Fear-avoidant beliefs can impact heavily on certain older people's recovery, as well as their longer-term health and wellbeing. Consideration of fear avoidance and taking steps to mitigate against this in the acute upper limb trauma setting will better serve these patients in their ongoing recovery from injury.

Surgical versus non-surgical interventions for treating patellar dislocation.

BACKGROUND: Patellar (knee cap) dislocation occurs when the patella disengages completely from the trochlear (femoral) groove. It affects up to 42/100,000 people, and is most prevalent in those aged 20 to 30 years old. It is uncertain whether surgical or non-surgical treatment is the best approach. This is important as recurrent dislocation occurs in up to 40% of people who experience a first time (primary) dislocation. This can reduce quality of life and as a result people have to modify their lifestyle. This review is needed to determine whether surgical or non-surgical treatment should be offered to people after patellar dislocation. OBJECTIVES: To assess the effects (benefits and harms) of surgical versus non-surgical interventions for treating people with primary or recurrent patellar dislocation. SEARCH METHODS: We searched the Cochrane Bone, Joint and Muscle Trauma Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, AMED, CINAHL, Physiotherapy Evidence Database and trial registries in December 2021. We contacted corresponding authors to identify additional studies. SELECTION CRITERIA: We included randomised and quasi-randomised controlled clinical trials evaluating surgical versus non-surgical interventions for treating primary or recurrent lateral patellar dislocation in adults or children. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were recurrent patellar dislocation, and patient-rated knee and physical function scores. Our secondary outcomes were health-related quality of life, return to former activities, knee pain during activity or at rest, adverse events, patient-reported satisfaction, patient-reported knee instability symptoms and subsequent requirement for knee surgery. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We included 10 studies (eight randomised controlled trials (RCTs) and two quasi-RCTs) of 519 participants with patellar dislocation. The mean ages in the individual studies ranged from 13.0 to 27.2 years. Four studies included children, mainly adolescents, as well as adults; two only recruited children. Study follow-up ranged from one to 14 years. We are unsure of the evidence for all outcomes in this review because we judged the certainty of the evidence to be very low. We downgraded each outcome by three levels. Reasons included imprecision (when fewer than 100 events were reported or the confidence interval (CI) indicated appreciable benefits as well as harms), risk of bias (when studies were at high risk of performance, detection and attrition bias), and inconsistency (in the event that pooled analysis included high levels of statistical heterogeneity). We are uncertain whether surgery lowers the risk of recurrent dislocation following primary patellar dislocation compared with non-surgical management at two to nine year follow-up. Based on an illustrative risk of recurrent dislocation in 348 people per 1000 in the non-surgical group, we found that 157 fewer people per 1000 (95% CI 209 fewer to 87 fewer) had recurrent dislocation between two and nine years after surgery (8 studies, 438 participants). We are uncertain whether surgery improves patient-rated knee and function scores. Studies measured this outcome using different scales (the Tegner activity scale, Knee Injury and Osteoarthritis Outcome Score, Lysholm, Kujala Patellofemoral Disorders score and Hughston visual analogue scale). The most frequently reported score was the Kujala Patellofemoral Disorders score. This indicated people in the surgical group had a mean score of 5.73 points higher at two to nine year follow-up (95% CI 2.91 lower to 14.37 higher; 7 studies, 401 participants). On this 100-point scale, higher scores indicate better function, and a change score of 10 points is considered to be clinically meaningful; therefore, this CI includes a possible meaningful improvement. We are uncertain whether surgery increases the risk of adverse events. Based on an assumed risk of overall incidence of complications during the first two years in 277 people out of 1000 in the non-surgical group, 335 more people per 1000 (95% CI 75 fewer to 723 more) had an adverse event in the surgery group (2 studies, 144 participants). Three studies (176 participants) assessed participant satisfaction at two to nine year follow-up, reporting little difference between groups. Based on an assumed risk of 763 per 1000 non-surgical participants reporting excellent or good outcomes, seven more participants per 1000 (95% CI 199 fewer to 237 more) reported excellent or good satisfaction. Four studies (256 participants) assessed recurrent patellar subluxation at two to nine year follow-up. Based on an assumed risk of patellar subluxation in 292 out of 1000 in the non-surgical group, 73 fewer people per 1000 (95% CI 146 fewer to 35 more) had patellar subluxation as a result of surgery. Slightly more people had subsequent surgery in the non-surgical group. Pooled two to nine year follow-up data from three trials (195 participants) indicated that, based on an assumed risk of subsequent surgery in 215 people per 1000 in the non-surgical group, 118 fewer people per 1000 (95% CI 200 fewer to 372 more) had subsequent surgery after primary surgery. AUTHORS' CONCLUSIONS: We are uncertain whether surgery improves outcome compared to non-surgical management as the certainty of the evidence was very low. No sufficiently powered trial has examined people with recurrent patellar dislocation. Adequately powered, multicentre, randomised trials are needed. To inform the design and conduct of these trials, expert consensus should be achieved on the minimal description of both surgical and non-surgical interventions, and the pathological variations that may be relevant to both choice of these interventions.

Supporting patients to prepare for total knee replacement: Evidence-, theory- and person-based development of a 'Virtual Knee School' digital intervention.

INTRODUCTION: Digital delivery of pre-operative total knee replacement (TKR) education and prehabilitation could improve patient outcomes pre- and post-operatively. Rigorously developing digital interventions is vital to help ensure they achieve their intended outcomes whilst mitigating their potential drawbacks. OBJECTIVE: To develop a pre-operative TKR education and prehabilitation digital intervention, the 'Virtual Knee School' (VKS). METHODS: The VKS was developed using an evidence-, theory- and person-based approach. This involved a mixed methods design with four phases. The first three focused on planning the VKS. The final phase involved creating a VKS prototype and iteratively refining it through concurrent think-aloud interviews with nine patients who were awaiting/had undergone TKR. Meta-inferences were generated by integrating findings from all the phases. ISRCTN registration of the overall project was obtained on 24 April 2020 (ISRCTN11759773). RESULTS: Most participants found the VKS prototype acceptable overall and considered it a valuable resource. Conversely, a minority of participants felt the prototype's digital format or content did not meet their individual needs. Participants' feedback was used to refine the prototype's information architecture, design and content. Two meta-inferences were generated and recommend: 1. Comprehensive pre-operative TKR education and prehabilitation support should be rapidly accessible in digital and non-digital formats. 2. Pre-operative TKR digital interventions should employ computer- and self-tailoring to account for patients' individual needs and preferences. CONCLUSIONS: Integrating evidence, theory and stakeholders' perspectives enabled the development of a promising VKS digital intervention for patients awaiting TKR. The findings suggest future research evaluating the VKS is warranted and provide recommendations for optimising pre-operative TKR care. PATIENT OR PUBLIC CONTRIBUTION: Patient and Public Involvement (PPI) was central throughout the project. For example, PPI representatives contributed to the project planning, were valued members of the Project Advisory Group, had key roles in developing the VKS prototype and helped disseminate the project findings.

Clinical and biomechanical factors associated with falls and rheumatoid arthritis: baseline cohort with longitudinal nested case-control study.

OBJECTIVE: To identify the clinical and biomechanical characteristics associated with falls in people with RA. METHODS: A total of 436 people ≥60 years of age with RA completed a 1 year prospective survey of falls in the UK. At baseline, questionnaires recorded data including personal and medical history, pain and fatigue scores, health-related quality of life (HRQoL), physical activity and medication history. The occurrence of falls wasmonitored prospectively over 12 months by monthly self-reporting. A nested sample of 30 fallers (defined as the report of one or more falls in 12 months) and 30 non-fallers was evaluated to assess joint range of motion (ROM), muscle strength and gait parameters. Multivariate regression analyses were undertaken to determine variables associated with falling. RESULTS: Compared with non-fallers (n = 236), fallers (n = 200) were older (P = 0.05), less likely to be married (P = 0.03), had higher pain scores (P < 0.01), experienced more frequent dizziness (P < 0.01), were frequently taking psychotropic medications (P = 0.02) and reported lower HRQoL (P = 0.02). Among those who underwent gait laboratory assessments, compared with non-fallers, fallers showed a greater anteroposterior (AP; P = 0.03) and medial-lateral (ML) sway range (P = 0.02) and reduced isokinetic peak torque and isometric strength at 60° knee flexion (P = 0.03). Fallers also showed shorter stride length (P = 0.04), shorter double support time (P = 0.04) and reduced percentage time in swing phase (P = 0.02) and in knee range of motion through the gait cycle (P < 0.01). CONCLUSION: People with RA have distinct clinical and biomechanical characteristics that place them at increased risk of falling. Assessment for these factors may be important to offer more targeted rehabilitation interventions.

Exercise for acutely hospitalised older medical patients.

BACKGROUND: Approximately 30% of hospitalised older adults experience hospital-associated functional decline. Exercise interventions that promote in-hospital activity may prevent deconditioning and thereby maintain physical function during hospitalisation. This is an update of a Cochrane Review first published in 2007. OBJECTIVES: To evaluate the benefits and harms of exercise interventions for acutely hospitalised older medical inpatients on functional ability, quality of life (QoL), participant global assessment of success and adverse events compared to usual care or a sham-control intervention. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was May 2021. SELECTION CRITERIA: We included randomised or quasi-randomised controlled trials evaluating an in-hospital exercise intervention in people aged 65 years or older admitted to hospital with a general medical condition. We excluded people admitted for elective reasons or surgery. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our major outcomes were 1. independence with activities of daily living; 2. functional mobility; 3. new incidence of delirium during hospitalisation; 4. QoL; 5. number of falls during hospitalisation; 6. medical deterioration during hospitalisation and 7. participant global assessment of success. Our minor outcomes were 8. death during hospitalisation; 9. musculoskeletal injuries during hospitalisation; 10. hospital length of stay; 11. new institutionalisation at hospital discharge; 12. hospital readmission and 13. walking performance. We used GRADE to assess certainty of evidence for each major outcome. We categorised exercise interventions as: rehabilitation-related activities (interventions designed to increase physical activity or functional recovery, but did not follow a specified exercise protocol); structured exercise (interventions that included an exercise intervention protocol but did not include progressive resistance training); and progressive resistance exercise (interventions that included an element of progressive resistance training). MAIN RESULTS: We included 24 studies (nine rehabilitation-related activity interventions, six structured exercise interventions and nine progressive resistance exercise interventions) with 7511 participants. All studies compared exercise interventions to usual care; two studies, in addition to usual care, used sham interventions. Mean ages ranged from 73 to 88 years, and 58% of participants were women. Several studies were at high risk of bias. The most common domain assessed at high risk of bias was measurement of the outcome, and five studies (21%) were at high risk of bias arising from the randomisation process. Exercise may have no clinically important effect on independence in activities of daily living at discharge from hospital compared to controls (16 studies, 5174 participants; low-certainty evidence). Five studies used the Barthel Index (scale: 0 to 100, higher scores representing greater independence). Mean scores at discharge in the control groups ranged from 42 to 96 points, and independence in activities of daily living was 1.8 points better (0.43 worse to 4.12 better) with exercise compared to controls. The minimally clinical important difference (MCID) is estimated to be 11 points. We are uncertain regarding the effect of exercise on functional mobility at discharge from the hospital compared to controls (8 studies, 2369 participants; very low-certainty evidence). Three studies used the Short Physical Performance Battery (SPPB) (scale: 0 to 12, higher scores representing better function) to measure functional mobility. Mean scores at discharge in the control groups ranged from 3.7 to 4.9 points on the SPPB, and the estimated effect of the exercise interventions was 0.78 points better (0.02 worse to 1.57 better). A change of 1 point on the SPPB represents an MCID. We are uncertain regarding the effect of exercise on the incidence of delirium during hospitalisation compared to controls (7 trials, 2088 participants; very low-certainty evidence). The incidence of delirium during hospitalisation was 88/1091 (81 per 1000) in the control group compared with 70/997 (73 per 1000; range 47 to 114) in the exercise group (RR 0.90, 95% CI 0.58 to 1.41). Exercise interventions may result in a small clinically unimportant improvement in QoL at discharge from the hospital compared to controls (4 studies, 875 participants; low-certainty evidence). Mean QoL on the EuroQol 5 Dimensions (EQ-5D) visual analogue scale (VAS) (scale: 0 to 100, higher scores representing better QoL) ranged between 48.9 and 64.7 in the control group at discharge from the hospital, and QoL was 6.04 points better (0.9 better to 11.18 better) with exercise. A change of 10 points on the EQ-5D VAS represents an MCID. No studies measured participant global assessment of success. Exercise interventions did not affect the risk of falls during hospitalisation (moderate-certainty evidence). The incidence of falls was 31/899 (34 per 1000) in the control group compared with 31/888 (34 per 1000; range 20 to 57) in the exercise group (RR 0.99, 95% CI 0.59 to 1.65). We are uncertain regarding the effect of exercise on the incidence of medical deterioration during hospitalisation (very low-certainty evidence). The incidence of medical deterioration in the control group was 101/1417 (71 per 1000) compared with 96/1313 (73 per 1000; range 44 to 120) in the exercise group (RR 1.02, 95% CI 0.62 to 1.68). Subgroup analyses by different intervention categories and by the use of a sham intervention were not meaningfully different from the main analyses. AUTHORS' CONCLUSIONS: Exercise may make little difference to independence in activities of daily living or QoL, but probably does not result in more falls in older medical inpatients. We are uncertain about the effect of exercise on functional mobility, incidence of delirium and medical deterioration. Certainty of evidence was limited by risk of bias and inconsistency. Future primary research on the effect of exercise on acute hospitalisation could focus on more consistent and uniform reporting of participant's characteristics including their baseline level of functional ability, as well as exercise dose, intensity and adherence that may provide an insight into the reasons for the observed inconsistencies in findings.

Increased proportion of alcohol-related trauma in a South London major trauma centre during lockdown: A cohort study.

PURPOSE: Alcohol has been associated with 10%-35% trauma admissions and 40% trauma-related deaths globally. In response to the COVID-19 pandemic, the United Kingdom entered a state of "lockdown" on March 23, 2020. Restrictions were most significantly eased on June 1, 2020, when shops and schools re-opened. The purpose of this study was to quantify the effect of lockdown on alcohol-related trauma admissions. METHODS: All adult patients admitted as "trauma calls" to a London major trauma centre during April 2018 and April 2019 (pre-lockdown, n = 316), and 1st April-31st May 2020 (lockdown, n = 191) had electronic patient records analysed retrospectively. Patients' blood alcohol level and records of intoxication were used to identify alcohol-related trauma. Trauma admissions from pre-lockdown and lockdown cohorts were compared using multiple regression analyses. RESULTS: Alcohol-related trauma was present in a significantly higher proportion of adult trauma calls during lockdown (lockdown 60/191 (31.4%), vs. pre-lockdown 62/316 (19.6%); (odds ratio (OR): 0.83, 95% CI: 0.38-1.28, p < 0.001). Lockdown was also associated with increased weekend admissions of trauma (lockdown 125/191 weekend (65.5%) vs. pre-lockdown 179/316 (56.7%); OR: 0.40, 95% CI: 0.79 to -0.02, p = 0.041). No significant difference existed in the age, gender, or mechanism between pre-lockdown and lockdown cohorts (p > 0.05). CONCLUSIONS: The United Kingdom lockdown was independently associated with an increased proportion of alcohol-related trauma. Trauma admissions were increased during the weekend when staffing levels are reduced. With the possibility of further global "waves" of COVID-19, the long-term repercussions of dangerous alcohol-related behaviour to public health must be addressed.

Orthopaedic physiotherapists' perceptions of mechanisms for observed variation in the implementation of physiotherapy practices in the early postoperative phase after hip fracture: a UK qualitative study.

OBJECTIVE: to explore physiotherapists' perceptions of mechanisms to explain observed variation in early postoperative practice after hip fracture surgery demonstrated in a national audit. METHODS: a qualitative semi-structured interview study of 21 physiotherapists working on orthopaedic wards at seven hospitals with different durations of physiotherapy during a recent audit. Thematic analysis of interviews drawing on Normalisation Process Theory to aid interpretation of findings. RESULTS: four themes were identified: achieving protocolised and personalised care; patient and carer engagement; multidisciplinary team engagement across the care continuum and strategies for service improvement. Most expressed variation from protocol was legitimate when driven by what is deemed clinically appropriate for a given patient. This tailored approach was deemed essential to optimise patient and carer engagement. Participants reported inconsistent degrees of engagement from the multidisciplinary team attributing this to competing workload priorities, interpreting 'postoperative physiotherapy' as a single professional activity rather than a care delivery approach, plus lack of integration between hospital and community care. All participants recognised changes needed at both structural and process levels to improve their services. CONCLUSION: physiotherapists highlighted an inherent conflict between their intention to deliver protocolised care and allowing for an individual patient-tailored approach. This conflict has implications for how audit results should be interpreted, how future clinical guidelines are written and how physiotherapists are trained. Physiotherapists also described additional factors explaining variation in practice, which may be addressed through increased engagement of the multidisciplinary team and resources for additional staffing and advanced clinical roles.

Consensus on pre-operative total knee replacement education and prehabilitation recommendations: a UK-based modified Delphi study.

BACKGROUND: Over 90,000 total knee replacement (TKR) procedures are performed annually in the United Kingdom (UK). Patients awaiting TKR face long delays whilst enduring severe pain and functional limitations. Almost 20% of patients who undergo TKR are not satisfied post-operatively. Optimising pre-operative TKR education and prehabilitation could help improve patient outcomes pre- and post-operatively; however, current pre-operative TKR care varies widely. Definitive evidence on the optimal content and delivery of pre-operative TKR care is lacking. This study aimed to develop evidence- and consensus-based recommendations on pre-operative TKR education and prehabilitation. METHODS: A UK-based, three-round, online modified Delphi study was conducted with a 60-member expert panel. All panellists had experience of TKR services as patients (n = 30) or professionals (n = 30). Round 1 included initial recommendations developed from a mixed methods rapid review. Panellists rated the importance of each item on a five-point Likert scale. Panellists could also suggest additional items in Round 1. Rounds 2 and 3 included all items from Round 1, new items suggested in Round 1 and charts summarising panellists' importance ratings from the preceding round. Free-text responses were analysed using content analysis. Quantitative data were analysed descriptively. All items rated as 'Important' or 'Very important' by at least 70% of all respondents in Round 3 were included in the final set of recommendations. RESULTS: Fifty-five panellists (92%) (patients n = 26; professionals n = 29) completed Round 3. Eighty-six recommendation items were included in Round 1. Fifteen new items were added in Round 2. Rounds 2 and 3 therefore included 101 items. Seventy-seven of these reached consensus in Round 3. Six items reached consensus amongst patient or professional panellists only in Round 3. The final set of recommendations comprises 34 education topics, 18 education delivery approaches, 10 exercise types, 13 exercise delivery approaches and two other treatments. CONCLUSIONS: This modified Delphi study developed a comprehensive set of recommendations that represent a useful resource for guiding decision-making on the content and delivery of pre-operative TKR education and prehabilitation. The recommendations will need to be interpreted and reviewed periodically in light of emerging evidence.

Anticholinergic drugs and incident dementia, mild cognitive impairment and cognitive decline: a meta-analysis.

BACKGROUND: the long-term effect of the use of drugs with anticholinergic activity on cognitive function remains unclear. METHODS: we conducted a systematic review and meta-analysis of the relationship between anticholinergic drugs and risk of dementia, mild cognitive impairment (MCI) and cognitive decline in the older population. We identified studies published between January 2002 and April 2018 with ≥12 weeks follow-up between strongly anticholinergic drug exposure and the study outcome measurement. We pooled adjusted odds ratios (OR) for studies reporting any, and at least short-term (90+ days) or long-term (365+ days) anticholinergic use for dementia and MCI outcomes, and standardised mean differences (SMD) in global cognition test scores for cognitive decline outcomes. Statistical heterogeneity was measured using the I2 statistic and risk of bias using ROBINS-I. RESULTS: twenty-six studies (including 621,548 participants) met our inclusion criteria. 'Any' anticholinergic use was associated with incident dementia (OR 1.20, 95% confidence interval [CI] 1.09-1.32, I2 = 86%). Short-term and long-term use were also associated with incident dementia (OR 1.23, 95% CI 1.17-1.29, I2 = 2%; and OR 1.50, 95% CI 1.22-1.85, I2 = 90%). 'Any' anticholinergic use was associated with cognitive decline (SMD 0.15; 95% CI 0.09-0.21, I2 = 3%) but showed no statistically significant difference for MCI (OR 1.24, 95% CI 0.97-1.59, I2 = 0%). CONCLUSIONS: anticholinergic drug use is associated with increased dementia incidence and cognitive decline in observational studies. However, a causal link cannot yet be inferred, as studies were observational with considerable risk of bias. Stronger evidence from high-quality studies is needed to guide the management of long-term use.

Association between different methods of assessing blood pressure variability and incident cardiovascular disease, cardiovascular mortality and all-cause mortality: a systematic review.

BACKGROUND: Blood pressure variability (BPV) is a possible risk factor for adverse cardiovascular outcomes and mortality. There is uncertainty as to whether BPV is related to differences in populations studied, measurement methods or both. We systematically reviewed the evidence for different methods to assess blood pressure variability (BPV) and their association with future cardiovascular events, cardiovascular mortality and all-cause mortality. METHODS: Literature databases were searched to June 2019. Observational studies were eligible if they measured short-term BPV, defined as variability in blood pressure measurements acquired either over a 24-hour period or several days. Data were extracted on method of BPV and reported association (or not) on future cardiovascular events, cardiovascular mortality and all-cause mortality. Methodological quality was assessed using the CASP observational study tool and data narratively synthesised. RESULTS: Sixty-one studies including 3,333,801 individuals were eligible. BPV has been assessed by various methods including ambulatory and home-based BP monitors assessing 24-hour, "day-by-day" and "week-to-week" variability. There was moderate quality evidence of an association between BPV and cardiovascular events (43 studies analysed) or all-cause mortality (26 studies analysed) irrespective of the measurement method in the short- to longer-term. There was moderate quality evidence reporting inconsistent findings on the potential association between cardiovascular mortality, irrespective of methods of BPV assessment (17 studies analysed). CONCLUSION: An association between BPV, cardiovascular mortality and cardiovascular events and/or all-cause mortality were reported by the majority of studies irrespective of method of measurement. Direct comparisons between studies and reporting of pooled effect sizes were not possible.

Barriers to uptake of the hip fracture core outcome set: An international survey of 80 hip fracture trialists.

BACKGROUND: Core outcome sets are an agreed recommendation to inform the selection of outcome measures in clinical trials. There has been low uptake of the 2014 hip fracture core outcome set. The reasons for this remain unclear. The aim of this study was to understand the reasons for the non-adoption and approaches to increase adoption of the hip fracture core outcome set. METHODS: Randomised controlled trials from PubMed (2017-2019) and ClinicalTrials.gov (2015-2019) were identified. Corresponding authors for each identified trial (n = 302) were surveyed using five questions on awareness of the hip fracture core outcome set, reasons for non-adoption and approaches to increase adoption. Data were analysed descriptively using frequencies, mean values and standard deviations. RESULTS: Fifty-four percent of the respondents (n = 43) were aware of the concept of core outcome set. Only 15% (n = 12) based the outcome measure selection on the 2014 hip fracture core outcome set. Key reasons for non-adoption included the following: authors being unaware and perceived inappropriateness to their trial design. Eighty-six percent (n = 69) of respondents agreed to the need for increased awareness of core outcome sets through research training, academic and clinical journal requirements, and funding or publication stipulations. Eighty-eight percent (n = 70) of respondents indicated the current core outcome set required revision to focus on trials investigating people with cognitive impairment, caregivers, rehabilitation, surgical interventions and anaesthetic trial designs. CONCLUSION: Barriers to the adoption of the hip fracture core outcome set centre on education, awareness of the core outcome sets and applicability to the breath of hip fracture trial designs. Further consideration should be made to address these, to improve the harmonisation of outcome measures across hip fracture trials.

Enhanced rehabilitation and care models for adults with dementia following hip fracture surgery.

BACKGROUND: Hip fracture is a major injury that causes significant problems for affected individuals and their family and carers. Over 40% of people with hip fracture have dementia or cognitive impairment. The outcomes of these individuals after surgery are poorer than for those without dementia. It is unclear which care and rehabilitation interventions achieve the best outcomes for these people. This is an update of a Cochrane Review first published in 2013. OBJECTIVES: (a) To assess the effectiveness of models of care including enhanced rehabilitation strategies designed specifically for people with dementia following hip fracture surgery compared to usual care. (b) To assess for people with dementia the effectiveness of models of care including enhanced rehabilitation strategies that are designed for all older people, regardless of cognitive status, following hip fracture surgery, compared to usual care. SEARCH METHODS: We searched ALOIS (www.medicine.ox.ac.uk/alois), the Cochrane Dementia and Cognitive Improvement Group Specialised Register, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), CINAHL (EBSCOhost), Web of Science Core Collection (ISI Web of Science), LILACS (BIREME), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 16 October 2019. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials evaluating the effectiveness of any model of enhanced care and rehabilitation for people with dementia after hip fracture surgery compared to usual care. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion and extracted data. We assessed risk of bias of the included trials. We synthesised data only if we considered the trials to be sufficiently homogeneous in terms of participants, interventions, and outcomes. We used the GRADE approach to rate the overall certainty of evidence for each outcome. MAIN RESULTS: We included seven trials with a total of 555 participants. Three trials compared models of enhanced care in the inpatient setting with conventional care. Two trials compared an enhanced care model provided in inpatient settings and at home after discharge with conventional care. Two trials compared geriatrician-led care in-hospital to conventional care led by the orthopaedic team. None of the interventions were designed specifically for people with dementia, therefore the data included in the review were from subgroups of people with dementia or cognitive impairment participating in randomised controlled trials investigating models of care for all older people following hip fracture. The end of follow-up in the trials ranged from the point of acute hospital discharge to 24 months after discharge. We considered all trials to be at high risk of bias in more than one domain. As subgroups of larger trials, the analyses lacked power to detect differences between the intervention groups. Furthermore, there were some important differences in baseline characteristics of participants between the experimental and control groups. Using the GRADE approach, we downgraded the certainty of the evidence for all outcomes to low or very low. The effect estimates for almost all comparisons were very imprecise, and the overall certainty for most results was very low. There were no data from any study for our primary outcome of health-related quality of life. There was only very low certainty for our other primary outcome, activities of daily living and functional performance, therefore we were unable to draw any conclusions with confidence. There was low-certainty that enhanced care and rehabilitation in-hospital may reduce rates of postoperative delirium (odds ratio 0.04, 95% confidence interval (CI) 0.01 to 0.22, 2 trials, n = 141) and very low-certainty associating it with lower rates of some other complications. There was also low-certainty that, compared to orthopaedic-led management, geriatrician-led management may lead to shorter hospital stays (mean difference 4.00 days, 95% CI 3.61 to 4.39, 1 trial, n = 162). AUTHORS' CONCLUSIONS: We found limited evidence that some of the models of enhanced rehabilitation and care used in the included trials may show benefits over usual care for preventing delirium and reducing length of stay for people with dementia who have been treated for hip fracture. However, the certainty of these results is low. Data were available from only a small number of trials, and the certainty for all other results is very low. Determining the optimal strategies to improve outcomes for this growing population of patients should be a research priority.

A loaded self-managed exercise programme for patellofemoral pain: a mixed methods feasibility study.

BACKGROUND: A novel loaded self-managed exercise programme that includes pain education and self-management strategies may result in better outcomes for people with patellofemoral pain (PFP). However, establishing program feasibility is an essential first step before testing efficacy. The purpose of this study was to evaluate the feasibility and acceptability of conducting a definitive RCT which will evaluate the clinical and cost-effectiveness of a loaded self-managed exercise programme for people with PFP compared with usual physiotherapy. METHODS: In a mixed methods, pragmatic, randomised controlled feasibility study, 60 participants with PFP (57% female; mean age 29 years) were recruited from a physiotherapy clinic within a large UK teaching hospital. They were randomly allocated to receive either a loaded self-managed exercise programme (n = 30) or usual physiotherapy (n = 30). Feasibility indicators of process, resources, and management were collected through follow-up of standardised questionnaires six months after recruitment and semi-structured interviews with 20 participants and physiotherapists. RESULTS: Recruitment rate was 5 participants per month; consent rate was 99%; adherence to intervention appointments was 87%; completeness of questionnaire data was 100%; and adherence to intervention delivery was 95%. Three exercise diaries were returned at six months (5%). At six months, 25 questionnaire booklets were returned (9 in the loaded self-managed group, 16 in the usual physiotherapy group), with a total retention rate of 42%. At six months, 56% (5/9) of respondents in the loaded self-managed group and 56% (9/16) in the usual physiotherapy group were classified as 'recovered'. Both groups demonstrated improvements in average pain (VAS), kinesiophobia, pain catastrophizing, general self-efficacy and EQ-5D-5 L from baseline to six months. CONCLUSION: The results of this feasibility study confirm that it is feasible and acceptable to deliver a loaded self-managed exercise programme to adults with PFP in an NHS physiotherapy outpatient setting. However, between group differences in lost to follow up and poor exercise diary completion mean we are uncertain on some feasibility aspects. These methodological issues need addressing prior to conducting a definitive RCT. TRIAL REGISTRATION: ISRCTN 35272486 . Registered 19th December 2016.

Trajectory of social isolation following hip fracture: an analysis of the English Longitudinal Study of Ageing (ELSA) cohort.

Background: social isolation is defined as a lack of meaningful and sustained communication or interactions with social networks. There is limited understanding on the prevalence of social isolation and loneliness in people following hip fracture and no previous understanding of how this changes over time. Objective: to determine the prevalence and trajectory of social isolation and loneliness before a hip fracture, during the recovery phase and a minimum of 2 years post-hip fracture in an English population. Methods: data were from the English Longitudinal Study of Ageing (ELSA) cohort (2004/5-2014/15). The sample comprised of 215 participants who had sustained a hip fracture. Measures of social isolation and loneliness were analysed through multilevel modelling to determine their trajectories during three-time intervals (pre-fracture; interval at hip fracture and recovery; minimum 2 years post-fracture). The prevalence of social isolation and loneliness were determined pre- and post-fracture. Results: prevalence of social isolation was 19% post-hip fracture and loneliness 13% post-hip fracture. There was no statistically significant change in social isolation pre-fracture compared to a minimum of 2 years post-fracture (P = 0.78). Similarly, there was no statistically significant change in loneliness pre-fracture compared to a minimum of 2 years post-fracture (P = 0.12). Conclusion: this analysis has determined that whilst social isolation and loneliness do not change over time following hip fracture, these remain a significant problem for this population. Interventions are required to address these physical and psychological health needs. This is important as they may have short and longer term health benefits for people post-hip fracture.

Association between lower limb osteoarthritis and incidence of depressive symptoms: data from the osteoarthritis initiative.

Background: osteoarthritis (OA) is associated with a number of medical morbidities. Although the prevalence of depression and depressive symptoms is presumed to be high in people with OA, no prospective comparative study has analyzed its incidence. Objective: to determine whether OA was associated with an increased odds of developing depressive symptoms. Design: longitudinal cohort study (follow-up: 4.2 years). Setting: data were gathered from the North American Osteoarthritis Initiative (OAI) dataset. Subjects: people at higher risk developing OA. Methods: OA diagnosis was defined as the presence of OA at hand, knee, hip, back/neck or other sites at baseline. Depressive symptoms were defined using the 20-item Center for Epidemiologic Studies-Depression (cut-off 16 points) after 4 years. Results: a total of 3,491 people without depressive symptoms at baseline were analyzed (1,506 with OA/1,985 without). Using an adjusted logistic regression analysis for 12 potential confounders, people with OA had a similar odds of depressive symptoms at follow-up compared to those without OA (odds ratio (OR): 1.26; 95% confidence of interval (CI): 0.95-1.67). However, multi-site OA (i.e. OA ≥2 sites; OR: 1.48, 95% CI: 1.07-2.05) and the specific presence of hip (OR: 1.72; 95% CI: 1.08-2.73) or knee OA (OR: 1.43; 95% CI: 1.03-1.98) were associated with a greater odds of developing depressive symptoms compared to people without OA. Conclusions: this is the first study of longitudinal data to demonstrate people with multi-site, hip or knee OA have a greater odds of developing depressive symptoms compared to people without OA. This suggests that OA may be associated with future mental health burden.

A systematic review of the physical activity assessment tools used in primary care.

Background: Primary care is an ideal setting for physical activity interventions to prevent and manage common long-term conditions. To identify those who can benefit from such interventions and to deliver tailored support, primary care professionals (e.g. GPs, practice nurses, physiotherapists, health care assistants) need reliable and valid tools to assess physical activity. However, there is uncertainty about the best-performing tool. Objective: To identify the tools used in the literature to assess the physical activity in primary care and describe their psychometric properties. Method: A systematic review of published and unpublished literature was undertaken up to 1 December 2016). Papers detailing physical activity measures, tools or approaches used in primary care consultations were included. A synthesis of the frequency and context of their use, and their psychometric properties, was undertaken. Studies were appraised using the Downs and Black critical appraisal tool and the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) initiative checklist. Results: Fourteen papers reported 10 physical activity assessment tools. The General Practice Physical Activity Questionnaire (GPPAQ) was most frequently reported. None of the assessment tools identified showed high reliability and validity. Intra-rater reliability ranged from kappa: 0.53 [Brief Physical Activity Assessment Tool (BPAAT)] to 0.67 (GPPAQ). Criterion validity ranged from Pearson's rho: 0.26 (GPPAQ) to 0.52 (Physical Activity Vital Sign). Concurrent validity ranged from kappa: 0.24 (GPPAQ) to 0.64 (BPAAT). Conclusion: The evidence base about physical activity assessment in primary care is insufficient to inform current practice.

Freedom of Information Act: scalpel or just a sharp knife?

The concluding statement of the Burns Commission, established to evaluate whether changes are needed to the Freedom of Information Act (FOIA), ruled no major legislative changes were required. As such Freedom of Information (FOI) legislation still enables anyone to obtain information from public authorities. In this brief report article we explore arguments regarding FOI as an instrument for healthcare research using an international research programme as a case study.

Is there a difference in physical activity levels in patients before and up to one year after unilateral total hip replacement? A systematic review and meta-analysis.

OBJECTIVE: To determine the difference in physical activity levels before and up to one year after unilateral primary total hip replacement. DATA SOURCES: A search was performed on 13 July 2016. Studies were eligible for inclusion if they presented preoperative and up to one year postoperative measures of physical activity for patients who had undergone unilateral primary total hip replacement. REVIEW METHODS: Any article that used a measure of physical activity pre and up to one year post-unilateral primary total hip replacement. Data was synthesised using a meta-analysis with 95% confidence intervals (CI), if appropriate. The Critical Appraisal Skills Programme cohort study checklist was used to assess the quality of evidence. RESULTS: From 6024 citations, 17 studies were selected: Nine studies were analysed in a meta-analysis and eight studies were analysed qualitatively. The quality of the evidence was 'low' to 'moderate'. There was no statistically significant difference in physical activity pre- to post-total hip replacement when assessed using: movement-related activity (mean difference (MD): -0.08; 95% CI: 1.60, 1.44; I2 = 0%; n = 77), percentage of 24-hours spent walking (MD: -0.21; 95% CI: -1.36, 0.93; I2 = 12%; n = 65), 6-minute walk test (MD: -60.85; 95% CI: -122.41, 0.72; I2 = 84%; n = 113) or the cardiopulmonary exercise test (MD: -0.24; 95% CI: -1.36, 0.87; I2 = 0%; n = 76). CONCLUSION: There is no statistically significant difference in physical activity levels before and up to one year after unilateral primary total hip replacement. However, the low to moderate methodological quality of the included articles should be taken into consideration when drawing conclusions.

The effect of targeted treatment on people with patellofemoral pain: a pragmatic, randomised controlled feasibility study.

BACKGROUND: Targeted treatment, matched according to specific clinical criteria e.g. hip muscle weakness, may result in better outcomes for people with patellofemoral pain (PFP). However, to ensure the success of future trials, a number of questions on the feasibility of a targeted treatment need clarification. The aim of the study was to explore the feasibility of matched treatment (MT) compared to usual care (UC) management for a subgroup of people with PFP determined to have hip weakness and to explore the mechanism of effect for hip strengthening. METHODS: In a pragmatic, randomised controlled feasibility study, 24 participants with PFP (58% female; mean age 29 years) were randomly allocated to receive either MT aimed specifically at hip strengthening, or UC over an eight-week period. The primary outcomes were feasibility outcomes, which included rates of adherence, attrition, eligibility, missing data and treatment efficacy. Secondary outcomes focused on the mechanistic outcomes of the intervention, which included hip kinematics. RESULTS: Conversion to consent (100%), missing data (0%), attrition rate (8%) and adherence to both treatment and appointments (>90%) were deemed successful endpoints. The analysis of treatment efficacy showed that the MT group reported a greater improvement for the Global Rating of Change Scale (62% vs. 9%) and the Anterior Knee Pain Scale (-5.23 vs. 1.18) but no between-group differences for either average or worst pain. Mechanistic outcomes showed a greatest reduction in peak hip internal rotation angle for the MT group (13.1% vs. -2.7%). CONCLUSION: This feasibility study indicates that a definitive randomised controlled trial investigating a targeted treatment approach is achievable. Findings suggest the mechanism of effect of hip strengthening may be to influence kinematic changes in hip function in the transverse plane.
