Real-world utilisation and switching between Janus kinase inhibitors in Australian patients with rheumatoid arthritis in the OPAL dataset.

OBJECTIVES: To describe use and treatment persistence for Janus kinase inhibitors (JAKi) in rheumatoid arthritis (RA) by line of therapy, and the mechanism of action for the drug switched to after JAKi discontinuation. METHODS: This was a retrospective, observational analysis using the OPAL dataset, a large collection of deidentified electronic medical records from 112 rheumatologists around Australia. Adult patients with RA were included if they initiated tofacitinib (TOF), baricitinib (BARI) or upadacitinib (UPA) between 1 October 2015 and 30 September 2021. Data were summarised using descriptive statistics. Kaplan-Meier survival was used to analyse treatment persistence. RESULTS: 5,900 patients initiated JAKi within the study window (TOF n=3,662, BARI n=1,875, UPA n=1,814). Median persistence was similar across JAKi within each line of therapy where there was sufficient follow-up, and almost 3 years for first-line: 34.9 months (95% CI 30.8, 40.7; n=1,408) for TOF, 33.6 months (95% CI 25.7, not reached; n=545) for BARI. While JAKi to JAKi switching occurred across all lines of therapy, switches to a tumour necrosis factor inhibitor (TNFi) were more frequent after first- or second-line JAKi. JAKi monotherapy use at baseline increased with line of therapy, and was highest at follow-up after switching to another JAKi. 'Lack of efficacy' was the most common reason for discontinuing JAKi. CONCLUSIONS: In this large analysis of Australian real-world practice separated by line of therapy, treatment persistence for JAKi was high overall subject to differential follow-up, but declined in later lines. JAKi to JAKi switching was observed across all lines of therapy.

Optimising patient outcomes: temporal trends in remission rates of rheumatoid arthritis patients in the Australian OPAL dataset between 2009 and 2022.

OBJECTIVE: To describe the trends in remission rates among RA patients in the OPAL dataset, spanning from 2009 to 2022, and provide insights into the effectiveness of evolving RA management approaches in real-world clinical settings. METHODS: Patients with a physician diagnosis of RA and at least 3 visits between 1 January 2009 and December 2022 were identified in the OPAL dataset, an aggregated collection of data extracted from the electronic medical records of patients managed by 117 Australian rheumatologists. Demographics, disease history, prescribed medications and proportions of patients in Disease Activity Score 28-joint count C-reactive protein (DAS28CRP)) categories (remission, low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA)) were described. RESULTS: A large population (n = 48,388) of eligible patients with RA were identified in the OPAL dataset. A consistent and substantial improvement in DAS28CRP remission rates were found in (i) all patients, (ii) patients managed on conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and (iii) patients treated with biological or targeted synthetic (b/ts)DMARD therapy, increasing from approximately 50% in 2009 to over 70% by 2022. The increase in DAS28CRP remission was accompanied by reduced proportions of patients in MDA and HDA states. CONCLUSION: This study highlights a consistent improvement in disease activity and rising remission rates among Australian RA patients within the OPAL dataset, offering the potential for enhanced patient outcomes and reduced disease burden.

Risk of vaccine preventable diseases in UK migrants: A serosurvey and concordance analysis.

Background: Vaccine preventable diseases (VPDs) such as measles and rubella cause significant morbidity and mortality globally every year. The World Health Organization (WHO), reported vaccine coverage for both measles and rubella to be 71 % in 2019, indicating an immunity gap. Migrants in the EU/EEA may be at high risk of VPDs due to under-immunisation and poor living conditions. However, there are limited data on VPD seroprotection rates amongst migrants living in the United Kingdom (UK). Methods: We conducted an exploratory cross-sectional serosurvey amongst a sample of adult migrants living in Leicester, UK to: (a) determine seroprotection rates for measles, varicella zoster, and rubella in this group; (b) identify risk factors associated with seronegativity and, (c) understand if self-reported vaccine or diseases history is an effective measure of seroprotection. Participants gave a blood sample and completed a questionnaire asking basic demographic details and vaccine and disease history for the three VPDs. We summarised the data using median and interquartile range (IQR) for non-parametric continuous variables and count and percentage for categorical variables. We used logistic regression to establish predictors of seroprotection against these diseases. We examined the reliability of self-reported vaccination/disease history for prediction of seroprotection through a concordance analysis. Results: 149 migrants were included in the analysis. Seroprotection rates were: varicella zoster 98 %, rubella 92.6 % and measles 89.3 %. Increasing age was associated with seroprotection (OR 1.07 95 % CI 1.01-1.13 for each year increase in age). Migrants from Africa and the Middle East (aOR 15.16 95 % CI 1.31 - 175.06) and South/East Asia and Pacific regions (aOR 15.43 95 %CI 2.38 - 100.00) are significantly more likely to be seroprotected against measles as compared to migrants from Europe and Central Asia. The proportions of migrants unsure about their vaccination and disease history combined were 53.0 % for measles; 57.7 % for rubella; 43.0 % for varicella. There was no agreement between self-reported vaccination/disease history and serostatus. Conclusion: Our findings suggest lower levels of seroprotection against measles in migrants living in Leicester, UK, with younger migrants and those from Europe and Central Asia more likely to lack seroprotection. A high proportion of surveyed migrants were unaware of their vaccination/disease history and self-reported vaccine/disease was a poor predictor of seroprotection against VPDs which is important for clinical decision-making regarding catch-up vaccination in this population. Our results, although derived from a small sample, suggest that there may be gaps in seroimmunity for certain VPDs in particular migrant populations. These findings should inform future qualitative studies investigating barriers to vaccine uptake in migrants and population-level seroprevalence studies aimed at determining individualised risk profiles based on demographic and migration factors.

The OMERACT whole-body MRI scoring system for inflammation in peripheral joints and entheses (WIPE) in spondyloarthritis - reference image atlas for the knee region.

OBJECTIVE: To develop a reference image atlas for the Outcome Measures in Rheumatology whole-body MRI scoring system for inflammation in peripheral joints and entheses (OMERACT MRI-WIPE) of the knee region. METHODS: Image examples of each pathology, location and grade, were collected and discussed at web-based, interactive meetings within the OMERACT MRI in Arthritis Working Group. Subsequently, reference images were selected by consensus. RESULTS: Reference images for each grade, pathology and location are depicted, along with definitions, reader rules and recommended MRI-sequences. CONCLUSION: The atlas guides scoring whole-body MRIs for inflammation in joints and entheses of the knee region according to MRI-WIPE methodology in clinical trials and cohorts.

Hip and pelvis region MRI reference image atlas for scoring inflammation in peripheral joints and entheses according to the OMERACT-MRI WIPE scoring system in patients with spondyloarthritis.

OBJECTIVE: To develop a reference image atlas for scoring the hip/pelvis region according to the OMERACT whole-body MRI scoring system for inflammation in peripheral joints and entheses (MRI-WIPE). METHODS: We collected image examples of each pathology, location and grade, discussed them at web-based, interactive meetings and, finally, selected reference images by consensus. RESULTS: Reference images for each grade and location of osteitis, synovitis and soft tissue inflammation are provided, as are definitions, reader rules and recommended MRI-sequences. CONCLUSION: A reference image atlas was created to guide scoring whole-body MRIs for arthritis and enthesitis in the hip/pelvis region in spondyloarthritis/psoriatic arthritis clinical trials and cohorts.

A high throughput immuno-affinity mass spectrometry method for detection and quantitation of SARS-CoV-2 nucleoprotein in human saliva and its comparison with RT-PCR, RT-LAMP, and lateral flow rapid antigen test.

OBJECTIVES: Many reverse transcription polymerase chain reaction (RT-PCR) methods exist that can detect SARS-CoV-2 RNA in different matrices. RT-PCR is highly sensitive, although viral RNA may be detected long after active infection has taken place. SARS-CoV-2 proteins have shorter detection windows hence their detection might be more meaningful. Given salivary droplets represent a main source of transmission, we explored the detection of viral RNA and protein using four different detection platforms including SISCAPA peptide immunoaffinity liquid chromatography-mass spectrometry (SISCAPA-LC-MS) using polyclonal capture antibodies. METHODS: The SISCAPA-LC MS method was compared to RT-PCR, RT-loop-mediated isothermal amplification (RT-LAMP), and a lateral flow rapid antigen test (RAT) for the detection of virus material in the drool saliva of 102 patients hospitalised after infection with SARS-CoV-2. Cycle thresholds (Ct) of RT-PCR (E gene) were compared to RT-LAMP time-to-positive (TTP) (NE and Orf1a genes), RAT optical densitometry measurements (test line/control line ratio) and to SISCAPA-LC-MS for measurements of viral protein. RESULTS: SISCAPA-LC-MS showed low sensitivity (37.7 %) but high specificity (89.8 %). RAT showed lower sensitivity (24.5 %) and high specificity (100 %). RT-LAMP had high sensitivity (83.0 %) and specificity (100.0 %). At high initial viral RNA loads (<20 Ct), results obtained using SISCAPA-LC-MS correlated with RT-PCR (R2 0.57, p-value 0.002). CONCLUSIONS: Detection of SARS-CoV-2 nucleoprotein in saliva was less frequent than the detection of viral RNA. The SISCAPA-LC-MS method allowed processing of multiple samples in <150 min and was scalable, enabling high throughput.

Comparative effectiveness of etanercept originator and biosimilar for treating rheumatoid arthritis: implications for cost-savings.

BACKGROUND AND AIMS: This study aimed to assess the comparative effectiveness of the etanercept (ETN) originator (Enbrel) and ETN biosimilar SB4 (Brenzys) as first-line treatment in patients with rheumatoid arthritis (RA), while also exploring the potential cost-savings associated with this approach in Australia. METHODS: Clinical data were obtained from the Optimising Patient outcomes in rheumatoLogy Australian real-world data set. Adult patients with RA who had initiated treatment with the ETN originator or biosimilar as their first-recorded biologic or targeted synthetic disease-modifying antirheumatic drug between 1 April 2017 and 31 December 2020 were included. Treatment persistence was analysed using survival analysis. Cost-savings were estimated based on data reported by the Australian National Prescribing Service MedicineWise. RESULTS: Propensity score matching followed by inverse probability of treatment weighting selected patients taking originator (n = 209) or biosimilar (n = 141) with similar baseline characteristics and eliminated small differences in baseline disease activity. The median time for 50% of the patients to stop treatment was 19.4 months (95% confidence interval [CI], 14.7-36.4 months) for the originator and 22.4 months (95% CI, 15.0-33.1 months) for the biosimilar (P = 0.95). As a result of pricing policies established by the Australian Government, introduction of the ETN biosimilar would have resulted in a cost-savings of over AU$9.5 million for 1 year of treatment for the patients reported in this study. CONCLUSION: Treatment persistence using either ETN originator or biosimilar was similar. The cost of all brands of ETN markedly reduced upon listing of the ETN biosimilar, resulting in significant savings for the Australian Government.

Protocol for a cluster randomised waitlist-controlled trial of a goal-based behaviour change intervention for employees in workplaces enrolled in health and wellbeing initiatives.

Many workplaces offer health and wellbeing initiatives to their staff as recommended by international and national health organisations. Despite their potential, the influence of these initiatives on health behaviour appears limited and evaluations of their effectiveness are rare. In this research, we propose evaluating the effectiveness of an established behaviour change intervention in a new workplace context. The intervention, 'mental contrasting plus implementation intentions', supports staff in achieving their health and wellbeing goals by encouraging them to compare the future with the present and to develop a plan for overcoming anticipated obstacles. We conducted a systematic review that identified only three trials of this intervention in workplaces and all of them were conducted within healthcare organisations. Our research will be the first to evaluate the effectiveness of mental contrasting outside a solely healthcare context. We propose including staff from 60 organisations, 30 in the intervention and 30 in a waitlisted control group. The findings will contribute to a better understanding of how to empower and support staff to improve their health and wellbeing. Trial registration: ISRCTN17828539.

Unintended consequences of the 18-week referral to treatment standard in NHS England: a threshold analysis.

OBJECTIVE: In 2012, an '18-week referral to treatment standard' was introduced in England. Among people on the list of those waiting for hospital treatment at a point in time, the standard states that at least '92% of patients should have been waiting for less than 18 weeks'. Targets can have unintended consequences, where patients are prioritised based on the target rather than clinical need. Such an effect will be evident as a spike in the number of hospital trusts at the target threshold, referred to as a threshold effect. This study examines for threshold effects across all non-specialist acute NHS England hospital trusts by financial year. METHODS: A retrospective observational study of publicly available data examined waiting times for patients on the waiting list. We examined trust performance against the 92% target by financial year, from 2015/16 to 2021/22, using Cattaneo et al's manipulation density test (test for discontinuity/spike in data around target threshold) for all patients and by type of treatment. RESULTS: The proportion of NHS hospital trusts meeting the 92% target deteriorated over time. From 2015/16 to 2019/20, there was strong evidence of a threshold effect at the 92% target (p<0.001). There was no evidence of a threshold effect in 2020/21 (p=0.063) or 2021/22 (p=0.090). Threshold effects were present across most types of treatment in 2016/17 and fewer types from 2017/18 onwards. CONCLUSION: We observed striking evidence of a threshold effect suggesting that while targets change behaviour, they do so in a selective way, focusing on the threshold rather than a pervasive improvement in practice. However, at the height of the pandemic, as almost no trusts could reach the target, the threshold effect disappeared.

Magnetic resonance imaging RAMRIS-SAFE score-A low-risk effective measure of rapid response to therapy in rheumatoid arthritis clinical trials.

AIM: To assess the rapidity of magnetic resonance imaging (MRI) measured synovitis (as measured by synovial thickening using the RAMRIS-SAFE score) and bone edema in active rheumatoid arthritis (RA) subjects treated with golimumab. Secondary aims: to correlate MRI measures with disabilities of the arm, shoulder, and hand (DASH), physician global (PhysG) and patient global (PatG) assessments. METHODS: Patients with active RA and inadequate response to methotrexate were recruited. Active RA was defined as RA with a Disease Activity Score of 28 joints - C-reactive protein ≥4.2 at screening AND active disease (synovitis and edema) of the chosen hand or wrist on MRI at screening, as determined by the central blinded MRI reader (PB). Outcomes measures were assessed at baseline, 2, 6, and 12 weeks. MRI results were interpreted by one experienced observer (PB), blinded to clinical measures. Pearson's correlation co-efficient (SPSS) was used to express the relationship between DASH, PhysG, PatG and MRI measures. RESULTS: Eighteen patients were included in the study. All subjects completed follow-up visits and MRI assessment. Mean age was 60.6 years (range 22-72), and 10 were female, 8 male, and disease duration was mean 4.72 years (range 1-28); all patients were taking background methotrexate. The changes in MRI synovial volume were evident by visit 2. The strongest correlations with the DASH for MRI parameters were total synovial thickening (0.923) and edema (0.921). CONCLUSION: Golimumab was associated with rapid improvement in clinical measures and patient-reported outcome measures. Mean synovial thickening demonstrated early rapid improvement. MRI synovial thickening demonstrated a strong correlation with DASH, PatG and PhysG.

RheuMetric Quantitative 0 to 10 Physician Estimates of Inflammation, Damage, and Distress in Rheumatoid Arthritis: Validation Against Reference Measures.

OBJECTIVE: To analyze a RheuMetric checklist, which includes four feasible physician 0 to 10 scores for DOCGL, inflammation (DOCINF), damage (DOCDAM), and distress (DOCSTR) for criterion and discriminant validity against standard reference measures. METHODS: A prospective, cross-sectional assessment was performed at one routine care visit at Liverpool Hospital, Sydney, Australia. Rheumatologists recorded DOCGL, DOCINF, DOCDAM, DOCSTR, and 28 joint counts for swelling (SJC), tenderness (TJC), and limited motion/deformity (DJC). Patients completed a multidimensional health assessment questionnaire (MDHAQ), which includes routine assessment of patient index data (RAPID3), fibromyalgia assessment screening tool (FAST4), and MDHAQ depression screen (MDS2). Laboratory tests and radiographic scores were recorded. RheuMetric estimates of inflammation, damage, and distress were compared with reference and other measures using correlations and linear regressions. RESULTS: In 173 patients with RA, variation in RheuMetric DOCINF was explained significantly by SJC and inversely by disease duration; variation in DOCDAM was explained significantly by DJC, radiographic scores, and physical function; and variation in DOCSTR was explained significantly by fibromyalgia and depression. CONCLUSION: RheuMetric DOCINF, DOCDAM, and DOCSTR estimates were correlated significantly and specifically with reference measures of inflammation, damage, and distress, documenting criterion and discriminant validity.

Comparative validation of the knee inflammation MRI scoring system and the MRI osteoarthritis knee score for semi-quantitative assessment of bone marrow lesions and synovitis-effusion in osteoarthritis: an international multi-reader exercise.

Background: Bone marrow lesions (BMLs) and synovitis on magnetic resonance imaging (MRI) are associated with symptoms and predict degeneration of articular cartilage in osteoarthritis (OA). Validated methods for their semiquantitative assessment on MRI are available, but they all have similar scoring designs and questionable sensitivity to change. New scoring methods with completely different designs need to be developed and compared to existing methods. Objectives: To compare the performance of new web-based versions of the Knee Inflammation MRI Scoring System (KIMRISS) with the MRI OA Knee Score (MOAKS) for quantification of BMLs and synovitis-effusion (S-E). Design: Retrospective follow-up cohort. Methods: We designed web-based overlays outlining regions in the knee that are scored for BML in MOAKS and KIMRISS. For KIMRISS, both BML and S-E are scored on consecutive sagittal slices. The performance of these methods was compared in an international reading exercise of 8 readers evaluating 60 pairs of scans conducted 1 year apart from cases recruited to the OA Initiative (OAI) cohort. Interobserver reliability for baseline status and baseline to 1 year change in BML and S-E was assessed by intra-class correlation coefficient (ICC) and smallest detectable change (SDC). Feasibility was assessed using the System Usability Scale (SUS). Results: Mean change in BML and S-E was minimal over 1 year. Pre-specified targets for acceptable reliability (ICC ⩾ 0.80 and ⩾ 0.70 for status and change scores, respectively) were achieved more frequently for KIMRISS for both BML and synovitis. Mean (95% CI) ICC for change in BML was 0.88 (0.83-0.92) and 0.69 (0.60-0.78) for KIMRISS and MOAKS, respectively. KIMRISS mean SUS usability score was 85.7 and at the 95th centile of ranking for usability versus a score of 55.4 and 20th centile for MOAKS. Conclusion: KIMRISS had superior performance metrics to MOAKS for quantification of BML and S-E. Both methods should be further compared in trials of new therapies for OA.

Comparative Effectiveness of First-Line Baricitinib in Patients With Rheumatoid Arthritis in the Australian OPAL Data Set.

OBJECTIVE: To analyze comparative treatment persistence for first-line baricitinib (BARI) versus first-line tumor necrosis factor inhibitor (TNFi) in patients with rheumatoid arthritis (RA) and for first-line BARI initiated as monotherapy versus first-line BARI initiated with at least one conventional synthetic disease-modifying antirheumatic drug (csDMARD). METHODS: Patients with RA who initiated BARI or TNFi as first-line biologic or targeted synthetic DMARD from October 1, 2015, to September 30, 2021, were identified in the OPAL data set. Drug survival times to 6, 12, and 24 months were analyzed using restricted mean survival time (RMST). Multiple imputation and inverse probability of treatment weighting were used to address missing data and nonrandom treatment assignment. RESULTS: A total of 545 patients initiated first-line BARI, including 118 as monotherapy and 427 as csDMARD combination therapy. Three thousand five hundred patients initiated first-line TNFi. There was no difference in drug survival to 6 or 12 months for BARI compared with TNFi; differences in RMST were 0.02 months (95% CI: -0.08 to 0.013; P = 0.65) and 0.31 months (95% CI: -0.02 to 0.63; P = 0.06), respectively. Patients in the BARI group had 1.00 month (95% CI: 0.14 to 1.86; P = 0.02) longer drug survival to 24 months. There was no difference in drug survival for BARI monotherapy compared with combination therapy, with differences in RMST to 6, 12, and 24 months of -0.19 months (95% CI: -0.50 to 0.12; P = 0.12), -0.35 months (95% CI: -1.17 to 0.42; P = 0.41), and -0.56 months (95% CI: -2.66 to 1.54; P = 0.60), respectively. CONCLUSION: In this comparative analysis, treatment persistence up to 24 months was significantly longer for first-line BARI compared with TNFi, but the effect size of 1.00 month is not clinically meaningful. There was no difference in persistence for BARI monotherapy versus combination therapy.

Comparative Effectiveness of Adalimumab vs Tofacitinib in Patients With Rheumatoid Arthritis in Australia.

Importance: There is a need for observational studies to supplement evidence from clinical trials, and the target trial emulation (TTE) framework can help avoid biases that can be introduced when treatments are compared crudely using observational data by applying design principles for randomized clinical trials. Adalimumab (ADA) and tofacitinib (TOF) were shown to be equivalent in patients with rheumatoid arthritis (RA) in a randomized clinical trial, but to our knowledge, these drugs have not been compared head-to-head using routinely collected clinical data and the TTE framework. Objective: To emulate a randomized clinical trial comparing ADA vs TOF in patients with RA who were new users of a biologic or targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD). Design, Setting, and Participants: This comparative effectiveness study emulating a randomized clinical trial of ADA vs TOF included Australian adults aged 18 years or older with RA in the Optimising Patient Outcomes in Australian Rheumatology (OPAL) data set. Patients were included if they initiated ADA or TOF between October 1, 2015, and April 1, 2021; were new b/tsDMARD users; and had at least 1 component of the disease activity score in 28 joints using C-reactive protein (DAS28-CRP) recorded at baseline or during follow-up. Intervention: Treatment with either ADA (40 mg every 14 days) or TOF (10 mg daily). Main Outcomes and Measures: The main outcome was the estimated average treatment effect, defined as the difference in mean DAS28-CRP among patients receiving TOF compared with those receiving ADA at 3 and 9 months after initiating treatment. Missing DAS28-CRP data were multiply imputed. Stable balancing weights were used to account for nonrandomized treatment assignment. Results: A total of 842 patients were identified, including 569 treated with ADA (387 [68.0%] female; median age, 56 years [IQR, 47-66 years]) and 273 treated with TOF (201 [73.6%] female; median age, 59 years [IQR, 51-68 years]). After applying stable balancing weights, mean DAS28-CRP in the ADA group was 5.3 (95% CI, 5.2-5.4) at baseline, 2.6 (95% CI, 2.5-2.7) at 3 months, and 2.3 (95% CI, 2.2-2.4) at 9 months; in the TOF group, it was 5.3 (95% CI, 5.2-5.4) at baseline, 2.4 (95% CI, 2.2-2.5) at 3 months, and 2.3 (95% CI, 2.1-2.4) at 9 months. The estimated average treatment effect was -0.2 (95% CI, -0.4 to -0.03; P = .02) at 3 months and -0.03 (95% CI, -0.2 to 0.1; P = .60) at 9 months. Conclusions and Relevance: In this study, there was a modest but statistically significant reduction in DAS28-CRP at 3 months for patients receiving TOF compared with those receiving ADA and no difference between treatment groups at 9 months. Three months of treatment with either drug led to clinically relevant average reductions in mean DAS28-CRP, consistent with remission.

Practitioners' views on community implementation of point-of-care ultrasound (POCUS) in the UK: a qualitative interview study.

BACKGROUND: Implementing Point-of-care ultrasound (POCUS) in community practice could help to decide upon and prioritise initial treatment, procedures and appropriate specialist referral or conveyance to hospital. A recent literature review suggests that image quality, portability and cost of ultrasound devices are all improving with widening indications for community POCUS, but evidence about community POCUS use is needed in the UK. We aimed to explore views of clinical practitioners, actively using ultrasound, on their experiences of using POCUS and potential facilitators and barriers to its wider implementation in community settings in the UK. METHODS: We conducted a qualitative interview study with practitioners from community and secondary care settings actively using POCUS in practice. A convenience sample of eligible participants from different clinical specialties and settings was recruited using social media adverts, through websites of relevant research groups and snowball sampling. Individual semi-structured interviews were conducted online using Microsoft Teams. These were recorded, transcribed verbatim, and analysed using a Framework approach supported by NVivo 12. RESULTS: We interviewed 16 practitioners aged between 40 and 62 years from different professional backgrounds, including paramedics, emergency physicians, general practitioners, and allied health professionals. Participants identified key considerations and facilitators for wider implementation of POCUS in community settings in the UK: resource requirements for deployment and support of working devices; sufficient time and a skilled workforce; attention to training, education and support needs; ensuring proper governance, guidelines and quality assurance; workforce considerations; enabling ease of use in assisting decision making with consideration of unintended consequences; and more robust evidence to support perceptions of improved patient outcomes and experience. CONCLUSIONS: POCUS could be useful for improving patient journey and health outcomes in community care, but this requires further research to evaluate outcomes. The facilitators identified could help make community POCUS a reality.

Retrospective evaluation of an intervention based on training sessions to increase the use of control charts in hospitals.

BACKGROUND: Statistical process control charts (SPCs) distinguish signal from noise in quality and safety metrics and thus enable resources to be targeted towards the most suitable actions for improving processes and outcomes. Nevertheless, according to a recent study, SPCs are not widely used by hospital boards in England. To address this, an educational training initiative with training sessions lasting less than one and a half days was established to increase uptake of SPCs in board papers. This research evaluated the impact of the training sessions on the inclusion of SPCs in hospital board papers in England. METHODS: We used a non-randomised controlled before and after design. Use of SPCs was examined in 40 publicly available board papers across 20 hospitals; 10 intervention hospitals and 10 control hospitals matched using hospital characteristics and time-period. Zero-inflated negative binomial regression models and t-tests compared changes in usage by means of a difference in difference approach. RESULTS: Across the 40 board papers in our sample, we found 6287 charts. Control hospitals had 9/1585 (0.6%) SPCs before the intervention period and 23/1900 (1.2%) after the intervention period, whereas intervention hospitals increased from 89/1235 (7%) before to 328/1567 (21%) after the intervention period; a relative risk ratio of 9 (95% CI 3 to 32). The absolute difference in use of SPCs was 17% (95% CI 6% to 27%) in favour of the intervention group. CONCLUSIONS: The results suggest that a scalable educational training initiative to improve use of SPCs within organisations can be effective. Future research could aim to overcome the limitations of observational research with an experimental design or seek to better understand mechanisms, decision-making and patient outcomes.
