Diagnostic accuracy of a large language model in rheumatology: comparison of physician and ChatGPT-4.

Pre-clinical studies suggest that large language models (i.e., ChatGPT) could be used in the diagnostic process to distinguish inflammatory rheumatic (IRD) from other diseases. We therefore aimed to assess the diagnostic accuracy of ChatGPT-4 in comparison to rheumatologists. For the analysis, the data set of Gräf et al. (2022) was used. Previous patient assessments were analyzed using ChatGPT-4 and compared to rheumatologists' assessments. ChatGPT-4 listed the correct diagnosis comparable often to rheumatologists as the top diagnosis 35% vs 39% (p = 0.30); as well as among the top 3 diagnoses, 60% vs 55%, (p = 0.38). In IRD-positive cases, ChatGPT-4 provided the top diagnosis in 71% vs 62% in the rheumatologists' analysis. Correct diagnosis was among the top 3 in 86% (ChatGPT-4) vs 74% (rheumatologists). In non-IRD cases, ChatGPT-4 provided the correct top diagnosis in 15% vs 27% in the rheumatologists' analysis. Correct diagnosis was among the top 3 in non-IRD cases in 46% of the ChatGPT-4 group vs 45% in the rheumatologists group. If only the first suggestion for diagnosis was considered, ChatGPT-4 correctly classified 58% of cases as IRD compared to 56% of the rheumatologists (p = 0.52). ChatGPT-4 showed a slightly higher accuracy for the top 3 overall diagnoses compared to rheumatologist's assessment. ChatGPT-4 was able to provide the correct differential diagnosis in a relevant number of cases and achieved better sensitivity to detect IRDs than rheumatologist, at the cost of lower specificity. The pilot results highlight the potential of this new technology as a triage tool for the diagnosis of IRD.

Knowledge on cause, clinical manifestation and treatment for fibromyalgia among medical doctors: A worldwide survey.

OBJECTIVES: Hench introduced the fibromyalgia syndrome almost 50 years ago. In the meantime, the prevalence has increased, the clinical criteria have changed and the way we explain (chronic) pain has altered. DESIGN: In the current study, we conducted a worldwide survey in which we investigate whether medical doctors are familiar with the American College of Rheumatology (ACR) criteria for fibromyalgia and, if so, whether these medical doctors adhere to the clinical guidelines following evidence-based treatments. RESULTS: In total, 286 medical doctors from 43 countries spread over 6 continents filled out the survey. In most of the countries, the diagnosis fibromyalgia was used. Only 10% adhere to the ACR criteria, widespread pain (44%), unrefreshed sleep (24%), fatigue (20%) and cognitive problems (8%) were most used diagnostic criteria. Of the respondents, 94 (32%) mentioned that the cause is unknown or idiopathic, but also a wide variety of other causes was mentioned. More than 70 different treatment options were provided, of which 24% of the responses were classified as according to the clinical guidelines. From this study, we conclude that many medical doctors do not follow the ACR criteria; the majority has an inappropriate knowledge of causes for fibromyalgia and that a minority of treatment advice adhere to the guidelines.

Barriers and Solutions for Pediatric Rheumatology Referrals in a Rural Area: Physician Survey Results From Montana State.

BACKGROUND: Currently, there are 9 states across the United States that do not have a pediatric rheumatologist, including the state of Montana. Patients in these states are often cared for by outreach clinics staffed by pediatric rheumatology (PR) providers from other states or looked after by in-state adult rheumatologists or in-state primary care providers. METHODS: Using a web-based survey, we determined barriers and potential solutions to PR referrals from referring providers (including primary care providers and subspecialists) in Montana state. RESULTS: Eighty-five Montana referring providers responded, with 44% being pediatric physicians and 33% being family medicine physicians. Other respondents were adult rheumatologists, pediatric and family medicine advanced practice providers, orthopedic surgeons, and pediatric subspecialists. Eighty-five percent of providers had previously referred a patient to PR. Referring providers rated difficulty referring MT patients to PR as 27 (on a linear numeric scale of 0-100, with 0 being very difficult) and noted lack of access to local pediatric rheumatologist as the most significant barrier to referral. The top patient barrier as perceived by 95% of providers was travel time. Potential solutions to improve care included presence of local pediatric rheumatologist with 50 miles, development of algorithms for common PR complaints, and outreach clinics. CONCLUSION: Referring providers in Montana report difficulty in referring to PR, with lack of access and travel time being key barriers. Improving access through expanding local PR workforce and increasing access through outreach clinics may help reduce these barriers.

[Health workforce development in rheumatology : A mapping exercise and wake-up call for health policy]. / Fachkräfteentwicklung in der Rheumatologie : Ein berufsstruktureller Überblick und gesundheitspolitischer Weckruf.

BACKGROUND AND OBJECTIVE: Health workforce shortage in German rheumatology has been identified as a healthcare service and delivery problem. Health policy has increased staffing targets, yet effective intervention strategies are lacking. This research aimed to systematically map the rheumatology workforce to improve the evidence for interventions and explore possibilities for more effective health workforce management. METHODS: The WHO National Health Workforce Accounts provided a conceptual framework for the mapping exercise. Four major sets of indicators were selected, comprising staffing levels, health labor market flows, composition and education/training. A comparison of age groups and time series was applied to explore trends. Public statistics and other secondary sources served our analysis using descriptive methodology. RESULTS: In Germany there are 1076 physicians specialized in internal medical rheumatology. Absolute numbers have nearly doubled (91%) since 2000 but with a strong demographic bias. Between 2000 and 2019 numbers markedly increased in the group aged 50 years and older but only by 9% in the younger group under 50 years; since 2010 the group aged 40-50 years even faces a decrease. In 2019, the absolute numbers of rheumatologists in retirement age exceeded those aged 40 years and under. Since 2015 an expanding workforce trend has overall flattened but this was strongest in the hospital sector; the numbers in resident training did not show any relevant growth. CONCLUSION: Health workforce trends reveal that an available number of rheumatologists cannot meet new health policy planning targets. There is a need for effective health workforce management, focusing on innovation in resident training, improved task delegation and gender equality.

[Specialist training situation in rheumatology from a trainer's perspective]. / Weiterbildungssituation in der Rheumatologie aus Sicht der Weiterbilder.

This article focuses on the training situation of rheumatologists from the perspective of trainers regarding the existing and potentially increasing deficits of specialists for internal medicine and rheumatology. According to the new regulations defining the rheumatologist training, a substantial part of the training schedule is required to be completed in a hospital setting in order to become a specialist rheumatologist. In this context, the increased training capacity necessitates additional hospital training positions. In addition, the rheumatology residents desire a structured training program. Significantly, the work-life balance is an important factor to make working as a specialist for internal medicine and rheumatology more attractive.

[Novel revision of the training regulations for German physicians-Consequences for trainees and trainers in rheumatology]. / Neue Musterweiterbildungsordnung ­ Konsequenzen für die Weiterzubildenden und die Weiterbilder in der Rheumatologie.

Rheumatology training is reorganized with the implementation of the revision of the training regulations for German physicians (MWBO) to become a specialist in internal medicine and rheumatology. This article focusses on novel aspects including far-reaching waiver of reference numbers, the professionally recommended training plan, the e­logbook, the regulation of specific training periods and the requirement of reapplication for the training authorization in addition to the contents of training. These aspects involve direct consequences for trainees and trainers.

2019 EULAR recommendations for the generic core competences of health professionals in rheumatology.

BACKGROUND/OBJECTIVES: To maintain and optimise the quality of care provided by health professionals in rheumatology (HPRs), adequate educational offerings are needed. This task force (TF) aimed to develop evidence-based recommendations for the generic core competences of HPRs, with specific reference to nurses, physical therapists (PTs) and occupational therapists (OTs) to serve as a basis for their postgraduate education. METHODS: The EULAR standardised operating procedures for the development of recommendations were followed. A TF including rheumatologists, nurses, PTs, OTs, patient-representatives, an educationalist, methodologists and researchers from 12 countries met twice. In the first TF meeting, 13 research questions were defined to support a systematic literature review (SLR). In the second meeting, the SLR evidence was discussed and recommendations formulated. Subsequently, level of evidence and strength of recommendation were assigned and level of agreement (LoA) determined (0-10 rating scale). RESULTS: Three overarching principles were identified and 10 recommendations were developed for the generic core competences of HPRs. The SLR included 79 full-text papers, 20 of which addressed the competences, knowledge, skills, attitudes and/or educational needs of HPRs from multiple professions. The average LoA for each recommendation ranged from 9.42 to 9.79. Consensus was reached both on a research and educational agenda. CONCLUSION: Evidence and expert opinion informed a set of recommendations providing guidance on the generic core competences of HPRs. Implementation of these recommendations in the postgraduate education of HPRs at the international and national level is advised, considering variation in healthcare systems and professional roles.

Substitution of hospital care with Primary Care Plus: differences in referral patterns according to specialty, specialist and diagnosis group.

BACKGROUND: Primary Care Plus (PC+) is an intervention where patients consult specialists in a primary care setting outside the hospital. Two facilities have been founded in the city of Maastricht, the Netherlands. Main aim is to achieve substitution of hospital care with primary care and hence reduce costs. The objective of this study is to evaluate referral patterns per specialty, specialist and diagnosis group, as input for deliberations to optimise substitution. METHODS: Prospectively collected referral data after PC+ consultations between November 2014 and March 2016 was analysed for eight participating specialties. Primary outcomes were differences in referral patterns per specialty, specialist and diagnosis group. Absolute counts and percentages were recorded for categorical variables, means and standard deviations for continuous variables. Statistical analyses were performed using IBM SPSS Statistics 23 (SPSS Inc., Chicago, IL). RESULTS: In total 4536 patients were seen in PC+; 3132 (69.0%) were referred back to the general practitioner (GP), whereas 1275 (28.1%) were referred to secondary care. Referral information of 130 (2.9%) patients was unknown. Large differences in referral numbers to secondary care after PC+ consultation were found between specialties (from 8.6% (gynaecology) to 43.8% (orthopaedic surgery)), specialists (14.5 to 65.2%) and diagnosis groups (11.1 to 93.4%). CONCLUSIONS: Wide variation in referral numbers to secondary care between specialties, specialists and diagnosis groups exists after PC+ consultations. This data indicates that deliberation and further research is needed in order to optimize substitution initiatives like PC+.

[Medical assistant-a profession in a state of flux]. / Medizinische Fachangestellte ­ ein Beruf im Wandel.

New treatment strategies and treatment possibilities as well as undertreatment due to the lack of medical specialists especially in rheumatology, necessitate a qualified further training of rheumatological assistant personnel. The increasing independent work of medical and rheumatological assistants expected by physicians with respect to patient management and practice organization, necessitates an intensive cooperation between the two professional groups. The aim is to guarantee the competent treatment of chronically ill patients with rheumatism. Finally, this concept offers the chance of additional professional qualifications for the rheumatological assistant profession and support for rheumatologists in the daily routine. This particularly applies to the engagement at several levels supported by the results of various studies, which indicate tasks that can be delegated to rheumatological assistants and confirm an improvement in the quality of patient care.

[What rheumatologists can learn from nephrologists]. / Was der Rheumatologe vom Nephrologen lernen kann.

Rheumatology and nephrology have some characteristics in common. In some places this leads to the marginalization of the respective other discipline, instead of an interdisciplinary morbidity-oriented approach. In order to cope with the complexity of systemic autoimmune diseases, a care mandate should be defined and interdisciplinary and cross-sectoral structures, such as interdisciplinary boards or special outpatient clinics should be established.

Ethics and Professionalism 2016.

Whether a reaction to events in the clinical arena, a consequence of technological innovation, or the legitimization of the marked ethos in health care, the field of medical ethics has become a complex domain in our time. Indeed, the ubiquity of ethical dilemmas in the provision of health care is well documented with more than 99% of primary care physicians reporting ethical problems arising in the conduct of their practices (1-3). Although commentary relating to this domain has most often originated in the primary care setting, hospital-based medicine and its ethics committees are another fertile source, as is medical research. Yet when one examines subspecialty medicine, a remarkable dearth of analysis and discourse pertaining to medical ethics emerges. This discussion is an attempt to address this deficit, at least as it pertains to one subspecialty: rheumatology. Leading with a brief overview of medical ethics writ large, perceptions concerning the ethical challenges arising in current rheumatic disease practice will be presented, hopefully enhancing awareness and sensitivity to the ethical challenges arising in modern day medical practice.

MACRA: A New Age for Physician Payments.

The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 introduced a new system of physician payments in the United States. This legislation and the complex rules written to enact the law intend to force a shift away from volume-based payments and into so called value-based payments. Physicians and other clinicians will be graded via quality and cost metrics and payments will be adjusted based on performance. Robust use of certified electronic health records is required under MACRA. Physicians will follow one of two payment reform tracks known as the Merit-Based Incentive Payment System (MIPS) and the Alternative Payment Model (APM) pathways. Although there are rheumatology and other specialty specific quality measures in the MIPS program, there are no rheumatology specific APMs to date. A thorough understating of MACRA is required for medical practices to survive the new era of payment reform.

Development of a Multidimensional Additive Points System for Determining Access to Rheumatology Services.

OBJECTIVE: In many countries, including New Zealand, the demand for rheumatology services exceeds their supply, resulting in some patients experiencing long delays or being denied access. The principal aim of this work was to create a validated, transparent, and fair system for determining access to rheumatology services. METHODS: A panel of 5 rheumatologists, 6 primary care physicians, and 4 nurse specialists ranked a series of 25 clinical scenarios in order of priority to see a rheumatologist. Important determining factors were weighted in an iterative process to generate a multidimensional additive point score to determine access to rheumatology service. RESULTS: The score comprises 6 domains of 2 to 4 items weighted to give a total score out of 100. The effect of the problem on the patient's life and role, the presence of an inflammatory rheumatic disease, appropriateness of current treatment, and the ability of the rheumatologist to influence the current symptoms and future prognosis were felt to be critical factors in determining access to the service. The score showed a strong correlation with the rankings agreed by the clinical panel, and the overall intraclass correlation coefficient for the rheumatologists was 0.698. CONCLUSIONS: Our score has face validity, is easy to perform, and has been assessed by an independent panel of rheumatologists as providing a fair system for determining access to rheumatology services. The system is acceptable to primary care physicians and has been adopted by our local primary care organizations.

Evaluating a competency framework for rheumatology nurses.

The Royal College of Nursing (RCN) competency framework for rheumatology nurses was developed in 2020. As part of the framework proposal, a service evaluation was planned following the framework's roll-out to determine its usefulness and acceptability. The aim of this evaluation was to explore rheumatology nurse specialists' answers to the research question: 'What was your experience of using the RCN's rheumatology competency framework?' A total of 14 rheumatology nurse specialists were interviewed and shared their opinions regarding the competency framework. Five themes were identified: personal usage; benefits to managers; inequalities and inequity in nursing; ideas for improvement; and general properties. The findings of this evaluation demonstrated the value of the framework, which enabled rheumatology nurse specialists to document the competency level they were working at and to identify their future training needs.

Lay Health Worker Interventions in Rheumatology: A Scoping Review.

OBJECTIVE: To determine next steps for lay health worker (LHW) intervention research, specifically in patients with rheumatic musculoskeletal diseases (RMDs), there is a need to establish what strategies have been effective for chronic disease management thus far. The goal of this scoping review is to collate the literature of LHW interventions for adults with RMDs to inform next steps for LHW research. METHODS: A comprehensive literature search was performed in the following databases from inception to September 2021: Ovid Medline, Ovid Embase, CINAHL, PsycINFO, and The Cochrane Library. Studies retrieved were then screened for eligibility against predefined inclusion and exclusion criteria. RESULTS: Twenty-two articles were eligible and included in this review. The most common RMDs studied, not mutually exclusive, were osteoarthritis (n = 13), rheumatoid arthritis (n = 9), and unspecified or other RMD (n = 14). Most studies had a homogenous patient population, enrolling White, non-Hispanic, or Latina women over the age of 60 (n = 13). Eight studies observed statistically significant results in the intervention arm compared with the control. Only one of these studies exhibited sustained treatment effects past one year. CONCLUSION: There are not enough data to conclude if LHW interventions have a positive, null, or negative effect on patients with RMDs. Future LHW interventions should specify a priori hypotheses, be powered to detect statistical significance for primary outcomes, employ a theoretical framework, include an active control, describe training protocols for LHWs, and increase minority representation to establish the effectiveness of LHWs for patients with RMDs.

Effect of a Billing Code to Reimburse Nurse-Supported Rheumatology Care on Health Care Costs and Access: An Interrupted Time Series Analysis.

OBJECTIVE: This study was undertaken to evaluate the impact of a Multidisciplinary Care Assessment (MCA) billing code on health system costs and access to care in British Columbia (BC). METHODS: Data on all people treated by rheumatologists in BC were obtained from five linked health administrative databases held by Population Data BC from April 1, 2006, to March 31, 2020. Rheumatologists were allocated to either the intervention (ever-billers) or control groups (never-billers). For the intervention group, the index date was the month of the first MCA code billing. For the control group the index dates were imputed from intervention index dates. Our analysis focused on a 48-month period (24 months before and after the index date). We evaluated the impact on two cost (costs related to rheumatoid arthritis [RA]; total health care costs) and access outcomes (rheumatology-related visits per rheumatologist; days between rheumatology visits for patients with RA) using an interrupted time series analysis. RESULTS: A total of 46 rheumatologists (31 intervention and 15 control) met our inclusion criteria. Introduction of the MCA was associated with a small but significant increase in RA-related costs that, at 2 years, translates to a net absolute change of $9.66 per patient per month, but no statistically significant changes in total health care costs. There was no statistically significant change in the number of rheumatology-related visits, but at 2 years there was a net absolute reduction in the median days between rheumatologist visits for patients with RA (6.3 days). CONCLUSION: The introduction of the MCA code was associated with a negligible increase in the RA-related costs and an improvement in access to ongoing care for patients.

A physician assistant rheumatology fellowship.

A rheumatology postgraduate fellowship for physician assistants was inaugurated in 2004 as a pilot initiative to supplement shortages in rheumatologists. An administrative analysis documented that each PA trainee achieved a high level of rheumatology exposure and proficiency. Classes in immunology, rheumatology, and internal medicine augmented clinical training. Faculty and trainees considered PA postgraduate training in rheumatology worthwhile.

Training the Next Generation of Rheumatologists: What Is the Best Way to Teach Fellows About Scleroderma?

Rheumatology is rich in educational opportunities, learning about a variety of diseases. Rheumatology subspecialty training is a time of unparalleled learning, and within the curriculum of a training program, the connective tissue diseases (CTDs) represent a unique challenge to the fellows. The challenge therein lies in the multisystem presentations they are faced with mastering. Scleroderma, as a rare and life-threatening CTD, remains one of the most difficult conditions to manage and treat. In this article, the authors focus on an approach to training the next generation of rheumatologists to take care of patients with scleroderma.
