RESUMEN
OBJECTIVES: Evidence for the comparative cost-effectiveness of intra-articular corticosteroid injection in people with hip osteoarthritis (OA) remains unclear. This study investigated the cost-effectiveness of best current treatment (BCT) comprising advice and education plus a single ultrasound-guided intra-articular hip injection (USGI) of 40 mg triamcinolone acetonide and 4 ml 1% lidocaine hydrochloride (BCT+US-T) versus BCT alone. METHODS: A trial-based cost-utility analysis of BCT+US-T compared with BCT was undertaken over 6 months. Patient-level cost data were obtained, and effectiveness was measured in terms of quality-adjusted life years (QALYs), allowing the calculation of cost per QALY gained from a United Kingdom (UK) National Health Service (NHS) perspective. RESULTS: BCT+US-T was associated with lower mean NHS costs (BCT+US-T minus BCT: £-161.6, 95% CI: £-583.95 to £54.18) and small but significantly higher mean QALYs than BCT alone over 6 months (BCT+US-T minus BCT: 0.0487, 95% CI: 0.0091, 0.0886). In the base case, BCT+US-T was the most cost-effective and dominated BCT alone. Differences in total costs were driven by number of visits to NHS consultants, private physiotherapists, and chiropractors, and hip surgery, which were more common with BCT alone than BCT+US-T. CONCLUSION: Intra-articular corticosteroid injection plus BCT (BCT+US-T) for patients with hip OA results in lower costs and better outcomes, and is highly cost-effective, compared with BCT alone.

RESUMEN
OBJECTIVE: To assess the longer term impact of the COVID-19 pandemic on the self-reported physical and mental health of people with inflammatory rheumatic diseases (IRDs). METHODS: Two thousand twenty-four patients with IRDs were randomly selected from electronic health records. Survey invitations were sent (August 2021 coinciding with relaxation of UK COVID-19 restrictions) using SMS and postal approaches. Self-reported data included demographics, shielding status and physical (MSK-HQ) and mental health (PHQ8 and GAD7). RESULTS: Six hundred thirty-nine people completed the survey (mean (SD) age 64.5 (13.1) years, 384 (60%) female). Moderate/severe impact of the pandemic on physical and mental health was reported by 250 (41%) and 241 (39%) respectively. One hundred seventy-two (29%) reported moderate/severe depression (PHQ8 ≥ 10) and 135 (22%) moderate/severe anxiety (GAD7 ≥ 10). Females reported greater impacts of the pandemic on physical health (44% vs 34%), mental health (44% vs 34%), arthritis symptoms (49% vs 36%) and lifestyle factors (weight gain and reduced exercise and physical activity) than males. The physical and mental impacts were less in people with RA compared with other IRDs. Physical health impacts did not differ between age groups, but younger patients reported greater impacts on mental health. CONCLUSION: The COVID-19 pandemic has had a significant impact on the physical and mental health of people with IRDs. These effects were greatest in females. Recovery needs to address the negative impact of the pandemic on lifestyle factors to minimise the long-term impacts for people with IRDs. Key Points ⢠The pandemic had a significant impact on long term physical and mental health in almost 40% of people with IRDs. ⢠The impact of the pandemic was greater in women for physical health, mental health and arthritis symptoms. ⢠Many people reported negative pandemic impacts on lifestyle factors including weight and physical activity.

Objectives: COVID-19 led to rapid uptake of digital health care. We sought to examine digital access, health and digital literacy, and impact on confidence and satisfaction with remote consultations in people with inflammatory rheumatic diseases (IRDs). Methods: People with IRDs (n = 2024) were identified from their electronic health record and invited to participate in a cross-sectional survey, using short message service (SMS) and postal approaches. Data were collected on demographics, self-reported diagnosis, access to and use of internet-enabled devices, health and digital literacy, together with confidence and satisfaction with remote consultations. Ethical approval was obtained (Ref 21/PR/0867). Results: Six hundred and thirty-nine (639) people completed the survey [mean (s.d.) age 64.5 (13.1) years, 384 (60.1%) female]. Two hundred and eighty-seven (44.9%) completed it online. One hundred and twenty-six (19.7%) people reported not having access to an internet-enabled device. Ninety-three (14.6%) reported never accessing the internet; this proportion was highest (23%) in people with RA. One hundred and seventeen (18%) reported limited health literacy. Even in those reporting internet use, digital literacy was only moderate. People with limited health or digital literacy or without internet access were less likely to report confidence or satisfaction with remote consultations. Conclusion: Limited health and digital literacy, lack of digital access and low reported internet use were common, especially in older people with RA. People with limited health literacy or limited digital access reported lower confidence and satisfaction with remote consultations. Digital implementation roll-out needs to take account of people requiring extra support to enable them to access care digitally or risks exacerbating health inequalities.
RESUMEN
OBJECTIVE: To compare the clinical effectiveness of adding a single ultrasound guided intra-articular hip injection of corticosteroid and local anaesthetic to advice and education in adults with hip osteoarthritis. DESIGN: Pragmatic, three arm, parallel group, single blind, randomised controlled trial. SETTING: Two community musculoskeletal services in England. PARTICIPANTS: 199 adults aged ≥40 years with hip osteoarthritis and at least moderate pain: 67 were randomly assigned to receive advice and education (best current treatment (BCT)), 66 to BCT plus ultrasound guided injection of triamcinolone and lidocaine, and 66 to BCT plus ultrasound guided injection of lidocaine. INTERVENTIONS: BCT alone, BCT plus ultrasound guided intra-articular hip injection of 40 mg triamcinolone acetonide and 4 mL 1% lidocaine hydrochloride, or BCT plus ultrasound guided intra-articular hip injection of 5 mL 1% lidocaine. Participants in the ultrasound guided arms were masked to the injection they received. MAIN OUTCOME MEASURES: The primary outcome was self-reported current intensity of hip pain (0-10 Numerical Rating Scale) over six months. Outcomes were self-reported at two weeks and at two, four, and six months. RESULTS: Mean age of the study sample was 62.8 years (standard deviation 10.0) and 113 (57%) were women. Average weighted follow-up rate across time points was 93%. Greater mean improvement in hip pain intensity over six months was reported with BCT plus ultrasound-triamcinolone-lidocaine compared with BCT: mean difference -1.43 (95% confidence interval -2.15 to -0.72), P<0.001; standardised mean difference -0.55 (-0.82 to -0.27). No difference in hip pain intensity over six months was reported between BCT plus ultrasound-triamcinolone-lidocaine compared with BCT plus ultrasound-lidocaine (-0.52 (-1.21 to 0.18)). The presence of ultrasound confirmed synovitis or effusion was associated with a significant interaction effect favouring BCT plus ultrasound-triamcinolone-lidocaine (-1.70 (-3.10 to -0.30)). One participant in the BCT plus ultrasound-triamcinolone-lidocaine group with a bioprosthetic aortic valve died from subacute bacterial endocarditis four months after the intervention, deemed possibly related to the trial treatment. CONCLUSIONS: Ultrasound guided intra-articular hip injection of triamcinolone is a treatment option to add to BCT for people with hip osteoarthritis.

Musculoskeletal disease is burdensome, costly and reported to be the 4th biggest reason for years lived with disability. Lower back and neck pain were the leading causes of disability in England from 1990 to 2016. Clinical Assessment and Treatment Services (CATs) have been established to provide expert assessment and management for this group of patients, with the aim of providing the majority of care within primary care, reducing referrals going through to secondary care. Such services require professionals with the appropriate skills and autonomy to fulfil this aim. This paper describes the development, implementation and evaluation of a bespoke Musculoskeletal Trainee programme within a large Clinical Assessment and Treatment Service. A 12-month training schedule was designed to assist the transition of a Physiotherapist (Band 7) to Advanced Practitioner level (Band 8a). Trainees worked through a series of competencies, captured their experiences and collected evidence of achievement during the 12-month period. Their experiences were explored using content analysis and common themes were identified. Three Physiotherapists were employed on the basis of undertaking this programme and successfully completed the programme. They highlighted the benefits of the programme being its bespoke nature and its flexibility to reflect their learning needs. Mentorship was a key component as they all identified that progressing to an autonomous role can be challenging. Learning new skills and working differently at a pace that suited them were seen as positives aspects. This programme describes the competencies and experiences of three individuals progressing to Advanced Practice Physiotherapists. This paper may assist those who manage and commission such services.

Radial access for cardiac catheterization and intervention in India has been growing steadily over the last decade with favorable clinical outcomes. However, its usage by interventional cardiologists varies greatly among Indian operators and hospitals due to large geographic disparities in health care delivery systems and practice patterns. It also remains unclear whether the advantages, as well as limitations of transradial (TR) intervention (as reported in the western literature), are applicable to developing countries like India or not. An evidence-based review involving various facets of radial procedure for cardiac catheterization, including practical, patient-related and technical issues was conducted by an expert committee that formed a part of Advancing Complex CoronariES Sciences through TransRADIAL intervention (ACCESS RADIAL™) Advisory Board. Emerging challenges in redefining TR management based on evidence supporting practices were discussed to formulate these final recommendations through consensus.

BACKGROUND: Evidence on the effectiveness of intra-articular corticosteroid injection for hip osteoarthritis is limited and conflicting. The primary objective of the Hip Injection Trial (HIT) is to compare pain intensity over 6 months, in people with hip OA between those receiving an ultrasound-guided intra-articular hip injection of corticosteroid with 1% lidocaine hydrochloride plus best current treatment with those receiving best current treatment alone. Secondary objectives are to determine specified comparative clinical and cost-effectiveness outcomes, and to explore, in a linked qualitative study, the lived experiences of patients with hip OA and experiences and impact of, ultrasound-guided intra-articular hip injection. METHODS: The HIT trial is a pragmatic, three-parallel group, single-blind, superiority, randomised controlled trial in patients with painful hip OA with a linked qualitative study. The current protocol is described, in addition to details and rationale for amendments since trial registration. 204 patients with moderate-to-severe hip OA will be recruited. Participants are randomised on an equal basis (1:1:1 ratio) to one of three interventions: (1) best current treatment, (2) best current treatment plus ultrasound-guided intra-articular hip injection of corticosteroid (triamcinolone acetonide 40 mg) with 1% lidocaine hydrochloride, or (3) best current treatment plus an ultrasound-guided intra-articular hip injection of 1% lidocaine hydrochloride alone. The primary endpoint is patient-reported hip pain intensity across 2 weeks, 2 months, 4 months and 6 months post-randomisation. Recruitment is over 29 months with a 6-month follow-up period. To address the primary objective, the analysis will compare participants' 'average' follow-up pain NRS scores, based on a random effects linear repeated-measures model. Data on adverse events are collected and reported in accordance with national guidance and reviewed by external monitoring committees. Individual semi-structured interviews are being conducted with up to 30 trial participants across all three arms of the trial. DISCUSSION: To ensure healthcare services improve outcomes for patients, we need to ensure there is a robust and appropriate evidence-base to support clinical decision making. The HIT trial will answer important questions regarding the clinical and cost-effectiveness of intra-articular corticosteroid injections. TRIAL REGISTRATION: ISRCTN: 50550256 , 28th July 2015.

Background: Synovitis is believed to play a role in producing symptoms in persons with hand osteoarthritis, but data on slow-acting anti-inflammatory treatments are sparse. Objective: To determine the effectiveness of hydroxychloroquine versus placebo as an analgesic treatment of hand osteoarthritis. Design: Randomized, double-blind, placebo-controlled clinical trial with 12-month follow-up. (ISRCTN registry number: ISRCTN91859104). Setting: 13 primary and secondary care centers in England. Participants: Of 316 patients screened, 248 participants (82% women; mean age, 62.7 years) with symptomatic (pain ≥4 on a 0- to 10-point visual analogue scale) and radiographic hand osteoarthritis were randomly assigned and 210 (84.7%) completed the 6-month primary end point. Intervention: Hydroxychloroquine (200 to 400 mg) or placebo (1:1) for 12 months with ongoing usual care. Measurements: The primary end point was average hand pain during the previous 2 weeks (on a 0- to 10-point numerical rating scale [NRS]) at 6 months. Secondary end points included self-reported pain and function, grip strength, quality of life, radiographic structural change, and adverse events. Baseline ultrasonography was done. Results: At 6 months, mean hand pain was 5.49 points in the placebo group and 5.66 points in the hydroxychloroquine group, with a treatment difference of -0.16 point (95% CI, -0.73 to 0.40 point) (P = 0.57). Results were robust to adjustments for adherence, missing data, and use of rescue medication. No significant treatment differences existed at 3, 6, or 12 months for any secondary outcomes. The percentage of participants with at least 1 joint with synovitis was 94% (134 of 143) on grayscale ultrasonography and 59% on power Doppler. Baseline structural damage or synovitis did not affect treatment response. Fifteen serious adverse events were reported (7 in the hydroxychloroquine group [3 defined as possibly related] and 8 in the placebo group). Limitation: Hydroxychloroquine dosage restrictions may have reduced efficacy. Conclusion: Hydroxychloroquine was no more effective than placebo for pain relief in patients with moderate to severe hand pain and radiographic osteoarthritis.

OBJECTIVE: To assess the sonographic frequency of synovial effusion, synovial hypertrophy, synovitis, and double contour sign at joints commonly affected by gout and whether these features differ according to serum urate levels, disease duration, and use of urate-lowering therapy. METHODS: Participants with gout were recruited from rheumatology clinics. A detailed clinical assessment was undertaken of gout history, co-morbidities, medication, alcohol consumption, height, weight, clinical synovitis, tophi, and serum urate. Sonographic examination of the metatarsophalangeal joints, ankles, knees, metacarpophalangeal joints, wrists and elbows for synovial effusion, synovial hypertrophy, synovitis and double contour sign was undertaken. The mean number of joints affected were compared according to serum urate (<360 µmol/L versus ≥360 µmol/L), urate-lowering therapy (yes/no), and disease duration (≤5 years versus>5 years). RESULTS: Forty patients participated in the study. Synovial effusion, synovial hypertrophy, synovitis, and double contour sign were identified in 36 (90%), 38 (95%), 24 (62%) and 37 (93%) participants respectively. Synovial effusion was seen most frequently at the knee (right 70%, left 68%) followed by the first metatarsophalangeal (right 48%, left 40%) and lesser metatarsophalangeal joints (right 45%, left 35%). Synovial hypertrophy, synovitis, and double contour sign were seen most frequently at the first metatarsophalangeal joint (hypertrophy: right 65%, left 60%; synovitis: right 18%, left 18%; double contour: right 60%, left 68%). These findings did not differ according to serum urate, disease duration, or use of urate-lowering therapy. CONCLUSION: Polyarticular sonography frequently identifies synovial effusion, synovial hypertrophy, synovitis and double contour sign in patients with gout, particularly at the metatarsophalangeal joints and knees.

Online surveys were conducted to determine the impact of endorser credibility, endorser effectiveness, and consumers' involvement in direct-to-consumer advertising. In a randomized posttest only study, using the elaboration likelihood model, survey participants (U.S. adults) were either exposed to a fictitious prescription drug ad with a celebrity or a noncelebrity endorser. There was no significant difference in credibility and effectiveness between the celebrity and the noncelebrity endorser. High involvement consumers viewed the ad more favorably and exhibited significantly stronger drug inquiry intentions during their next doctor visit. Further, consumers' involvement did not moderate the effect of celebrity endorser.

BACKGROUND: Little empirical evidence exists regarding the influence and outcomes of inappropriate medication use among elderly nursing home residents. OBJECTIVE: To identify the prevalence of inappropriate medication use among elderly patients in Georgia nursing homes using the Beers criteria and identify the relationship between inappropriate drug use and the likelihood of an adverse health outcome. METHODS: A cohort design was used to review 1117 patient medical records in 15 Georgia nursing homes with a high risk of polypharmacy. Prevalence of inappropriate medication use among elderly patients, as defined by the Beers criteria, was estimated. The adverse health outcomes of hospitalizations, emergency department visits, or deaths were identified from Medicaid claims data. RESULTS: A total of 519 (46.5%) patients received at least one inappropriate medication and 143 (12.8%) patients experienced at least one adverse health outcome. Logistic regression revealed that the total number of medications taken (OR 1.139, 95% CI 1.105 to 1.173) significantly increased the likelihood of receiving an inappropriate drug, while having a diagnosis of "dementia" (OR 0.748, 95% CI 0.565 to 0.991) decreased the likelihood. Inappropriate medication use increased the likelihood of experiencing at least one adverse health outcome more than twofold (OR 2.34, 95% CI 1.61 to 3.40). Propoxyphene use alone was significantly associated with the occurrence of an adverse health outcome (OR 2.39, 95% CI 1.54 to 3.71). CONCLUSIONS: Inappropriate drug use was common in our study cohort. Inappropriate use of medication in the elderly, particularly propoxyphene, is associated with a higher risk of adverse health outcomes.

OBJECTIVE: The heritability of disease activity and function in ankylosing spondylitis (AS) have been estimated at 0.51 and 0.63 (i.e., 51% and 63%), respectively. We examined the concordance of disease severity among family members in terms of disease activity, function, radiological change, prevalence of iritis, and juvenile onset. METHODS: Disease activity and functional impairment due to AS were studied using the Bath AS Disease Activity Index (BASDAI) and Functional Index (BASFI) self-administered questionnaires; radiographic involvement was measured using the Bath AS Radiology Index (BASRI) scale. Familial correlation of BASDAI and BASFI was assessed in 406 families with 2 or more cases, using the program PAP. Parent-child and sibling-sibling concordance for iritis and juvenile AS were also studied in these families. Heritability of radiological disease severity based on the BASRI was assessed in 29 families containing 60 affected individuals using the program SOLAR. RESULTS: Correlations between parent-child pairs for disease activity and function were 0.07 for both. Correlations between sibling pairs for disease activity and function were 0.27 and 0.36, respectively. The children of AS parents with iritis were more likely to develop iritis [27/71 (38%)] than children of non-iritis AS parents [13/70 (19%)] (p = 0.01). Parents with JAS were more likely to have children with JAS [17/30 (57%) compared to non-JAS parents 34/111 (30%)] (p = 0.002). The heritability of radiological disease severity based on the BASRI was 0.62. CONCLUSION: While correlation in severity between parent and child is poor, siblings do resemble each other in terms of severity, supporting the findings of segregation studies indicating significant genetic dominance in the heritable component of disease activity. Significant parent-child concordance for iritis and juvenile disease onset suggest that there are genetic risk factors for these traits independent of those determining the risk of AS itself. The finding of significant heritability of radiological change (BASRI) provides support using an objective measure for the observed heritability of the questionnaire-assessed disease severity scores, BASDAI and BASFI.

OBJECTIVE: To determine whether visual analog scales (VAS) can be used over the Internet to assess the patient with ankylosing spondylitis (AS) accurately or if the use of this different medium will affect the results. METHODS: Patients with AS (n = 50) attending a physiotherapy/educational course completed both an Internet based and a paper based version of the Bath Ankylosing Spondylitis Functional Index (BASFI) that uses VAS. The Internet version was completed twice to assess intrarespondent variation reliability and compared with the paper version to assess interrespondent variation reliability. Patients were also asked to assess ease of use and to suggest changes to the Internet version. RESULTS: The interclass coefficient of intra- and interrespondent reliability were 0.989 (p < 0.001) and 0.976 (p < 0.001), respectively. There was a 3% difference in assessments carried out over the Internet compared to those on paper and a 2% difference in repeatability of Internet assessed questionnaires. Bland and Altman plots showed a mean difference between paper compared to the Internet version was 0.0156 with 95% limits of agreement at -1.07 to 1.03. More than half the participants reported that the Internet version was easier to complete than the paper version (96% rated usability as 1 on a scale of 1-10, with 1 being extremely easy and 10 being impossible). CONCLUSION: Assessment of disease severity by VAS may be accurately carried out over the Internet. This means that the evaluation of disease status and the longterm followup of people in different countries and perhaps in different languages may now be possible, using the Internet.

The growth in direct-to-consumer advertising(DTCA)over the past two decades has facilitated the communication of prescription drug information directly to consumers. Data from a 1999 national survey are employed to determine the factors influencing consumers' opinions of the utility of DTC ads for health care decision making. We also analyze whether consumers use DTC ad information in health care decision making and who are the key drivers of such information utilization. The study results suggest that consumers have positive opinions of DTCA utility, varying across demographics and perceptions of certain advertisement features. Specifically, consumers value information about both risks and benefits, but the perception of risk information is more important in shaping opinions of ad utility than the perception of benefit information. Consumers still perceive, however that the quality of benefit information in DTC ads is better than that of risk information. Opinions about ad utility significantly influence whether information from DTC ads is used in health care decision making.

The proliferation of both manufacturer-controlled and independent medication-related websites has aroused concern among consumers and policy-makers concerning the trustworthiness of Web-based drug information. The authors examine consumers' trust in on-line prescription drug information and its influence on information search behavior. The study design involves a retrospective analysis of data from a 1998 national survey. The findings reveal that trust in drug information from traditional media sources such as television and newspapers transfers to the domain of the Internet. Furthermore, a greater trust in on-line prescription drug information stimulates utilization of the Internet for information search after exposure to prescription drug advertising.
