Medical cannabis use by rheumatology patients in routine clinical care: results from The Ontario Best Practices Research Initiative.

OBJECTIVES: Medical cannabis is often used to alleviate common symptoms in patients with chronic conditions. With cannabis legalisation in Canada and easier access, it is important that rheumatologists understand its potential impact on their practice. Among patients attending rheumatology clinics in Ontario we assessed: the prevalence of medical cannabis use; symptoms treated; rheumatologists' perceptions. METHODS: Eight rheumatology clinics recruited consecutive adult patients in a 3-part medical cannabis survey: the first completed by rheumatologists; the second by all patients; the third by medical cannabis users. Student's t-test and Chi-square test were used to compare medical cannabis users to never users. RESULTS: 799 patients participated, 163 (20.4%) currently using medical cannabis or within <2 years and 636 never users; most had rheumatoid arthritis (37.8%) or osteoarthritis (34.0%). Compared to never users, current/past-users were younger; more likely to be taking opioids/anti-depressants, have psychiatric/gastrointestinal disorders, and have used recreational cannabis (p<0.05); had higher physician (2.9 vs. 2.1) and patient (6.0 vs. 4.2) global scores, and pain (6.2 vs. 4.7) (p<0.0001). Pain (95.5%), sleeping (82.3%) and anxiety (58.9%) were the most commonly treated symptoms; 78.2% of current/past-users reported medical cannabis was at least somewhat effective. Most rheumatologists reported being uncomfortable to authorise medical cannabis, primarily due to lack of evidence, knowledge, and product standardisation. CONCLUSIONS: Medical cannabis use among rheumatology patients in Ontario was two-fold higher than that reported for the general population of similar age. Use was associated with more severe disease, pain, and prior recreational use. Reported lack of research, knowledge, and product standardisation were barriers for rheumatologist use authorisation.

Exploring the Health Informatics Occupational Group in the 2018 Australian Health Information Workforce Census.

There has been no empirical evidence about the health informatics workforce in Australia produced in the last ten years. This study reports the findings from an analysis of a subset of the 2018 Australian Health Informatics Workforce Census data. Analysing 420 responses that were identified as the occupational group Health Informatics, the results indicate that whilst most of the workforce is classified as aged (>45 years), many respondents are still relatively early in their health informatics careers. Furthermore, most do not possess any formal education in health informatics and almost a quarter undertake their health informatics role alongside another health-related role. The broad range of position titles and functions demonstrates the breadth within this workforce. Ongoing monitoring of this occupational group is required to inform workforce reform and renewal.

Planning for the Rheumatologist Workforce: Factors Associated With Work Hours and Volumes.

OBJECTIVE: The aim of this study was to evaluate factors associated with rheumatologists' clinical work hours and patient volumes based on a national workforce survey in rheumatology. METHODS: Adult rheumatologists who participated in a 2015 workforce survey were included (n = 255). Univariate analysis evaluated the relationship between demographics (sex, age, academic vs. community practice, billing fee for service vs. other plan, years in practice, retirement plans) and workload (total hours and number of ½-day clinics per week) or patient volumes (number of new and follow-up consults per week). Multiple linear regression models were used to evaluate the relationship between practice type, sex, age, and working hours or clinical volumes. RESULTS: Male rheumatologists had more ½-day clinics (p = 0.05) and saw more new patients per week (p = 0.001) compared with females. Community rheumatologists had more ½-day clinics and new and follow-up visits per week (all p < 0.01). Fee-for-service rheumatologists reported more ½-day clinics per week (p < 0.001) and follow-ups (p = 0.04). Workload did not vary by age, years in practice, or retirement plans. In multivariate analysis, community practice remained independently associated with higher patient volumes and more clinics per week. Female rheumatologists reported fewer clinics and fewer follow-up patients per week than males, but this did not affect the duration of working hours or new consultations. Age was not associated with work volumes or hours. CONCLUSIONS: Practice type and rheumatologist sex should be considered when evaluating rheumatologist workforce needs, as the proportion of female rheumatologists has increased over time and alternative billing practices have been introduced in many centers.

Perceived Versus Performance Fatigability in Patients With Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is a chronic, inflammatory disease that affects 1% of the general population. Fatigue is a common complaint of patients with RA, however their perceived fatigue may be more exacerbated than objective measures of fatigue may indicate. The assessment of fatigue is made complex due to inconsistent and vague terms used to define fatigue, and the task dependence of fatigability. Fatigue is defined as a state of exhaustion and decreased strength, while fatigability indicates an individual's susceptibility to fatigue. In order to offer some clarity to the manifestation of fatigue in clinical populations, in this review we outline that fatigue should be described with subsections that are related to the symptom, such as: perceived fatigability and performance fatigability. Where perceived fatigability indicates the subjective state of the individual and thus involves the individual's subjective measure of fatigue, performance fatigability would be measured through clinical and laboratory-based assessments that quantify the functional decline in performance. This review describes RA and the various neuromuscular changes associated with the disease that can lead to alterations in both perceived and performance fatigue. From there, we discuss fatigue and RA, how fatigue can be assessed, effects of exercise interventions on RA symptoms and fatigue, and recommendations for future studies investigating subjective and objective measures of fatigability.

The Development of a National Census of the Health Information Workforce: Expert Panel Recommendations.

BACKGROUND: There is a need to develop a national census of the health information workforce to inform the planning and forecasting of the workforce and inform education and training needs. Yet, this raises a number of issues that need to be incorporated into the planning stage. This paper discusses the issues and recommendations for the development of a national health information workforce census and an Expert Panel's recommendations for how we should proceed. METHODS: Nominated participants from Australia and New Zealand participated as Expert Panel members in focus groups to identify and discuss the issues. Recommendations were identified during the focus groups and documented for participant verification. These were then grouped into themes. RESULTS AND DISCUSSION: The themes of the issues and considerations identified in the focus groups were: Aim of the census; Census advertisement; Census delivery; Participants; Longitudinal study; Types of data elements; Data development and standards; Data ownership, access and governance; Global census; Dissemination of results.

Stand Up and Be Counted: Measuring and Mapping the Rheumatology Workforce in Canada.

OBJECTIVE: To characterize the practicing rheumatologist workforce, the Canadian Rheumatology Association (CRA) launched the Stand Up and Be Counted workforce survey in 2015. METHODS: The survey was distributed electronically to 695 individuals, of whom 519 were expected to be practicing rheumatologists. Demographic and practice information were elicited. We estimated the number of full-time equivalent rheumatologists per 75,000 population from the median proportion of time devoted to clinical practice multiplied by provincial rheumatologist numbers from the Canadian Medical Association. RESULTS: The response rate was 68% (355/519) of expected practicing rheumatologists (304 were in adult practice, and 51 pediatric). The median age was 50 years, and one-third planned to retire within the next 5-10 years. The majority (81%) were university-affiliated. Rheumatologists spent a median of 70% of their time in clinical practice, holding 6 half-day clinics weekly, with 10 new consultations and 45 followups seen per week. Work characteristics varied by type of rheumatologist (adult or pediatric) and by practice setting (community- or university-based). We estimated between 0 and 0.8 full-time rheumatologists per 75,000 population in each province. This represents a deficit of 1 to 77 full-time rheumatologists per province/territory to meet the CRA recommendation of 1 rheumatologist per 75,000 population, depending on the province/territory. CONCLUSION: Our results highlight a current shortage of rheumatologists in Canada that may worsen in the next 10 years because one-third of the workforce plans to retire. Efforts to encourage trainees to enter rheumatology and strategies to support retention are critical to address the shortage.

Measuring the Rheumatology Workforce in Canada: A Literature Review.

OBJECTIVE: The number of rheumatologists per capita has been proposed as a performance measure for arthritis care. This study reviews what is known about the rheumatologist workforce in Canada. METHODS: A systematic search was conducted in EMBASE and MEDLINE using the search themes "rheumatology" AND "workforce" AND "Canada" from 2000 until December 2014. Additionally, workforce databases and rheumatology websites were searched. Data were abstracted on the numbers of rheumatologists, demographics, retirement projections, and barriers to healthcare. RESULTS: Twenty-five sources for rheumatology workforce information were found: 6 surveys, 14 databases, 2 patient/provider resources, and 3 epidemiologic studies. Recent estimates say there are 398 to 428 rheumatologists in Canada, but there were limited data on allocation of time to clinical practice. Although the net number of rheumatologists has increased, the mean age was ≥ 47.7 years, and up to one-third are planning to retire in the next decade. There is a clustering of rheumatologists around academic centers, while some provinces/territories have suboptimal ratios of rheumatologists per capita (range 0-1.1). Limited information was found on whether rural areas are receiving adequate services. The most consistent barrier reported by rheumatologists was lack of allied health professionals. CONCLUSION: In Canada there are regional disparities in access to rheumatologist care and an aging rheumatologist workforce. To address these workforce capacity issues, better data are needed including information on clinical full-time equivalents, delivery of care to remote communities, and use of alternative models of care to increase clinical capacity.

Intrauterine growth restriction leads to changes in sulfur amino acid metabolism, but not global DNA methylation, in Yucatan miniature piglets.

Intrauterine growth restriction (IUGR), in both animals and humans, has been linked to metabolic syndrome later in life. There has been recent evidence that perturbations in sulfur amino acid metabolism may be involved in this early programming phenomenon. Methionine is the precursor for cellular methylation reactions and for the synthesis of cysteine. It has been suggested that the mechanism behind the "fetal origins" of adult diseases may be epigenetic, involving DNA methylation. Because we have recently demonstrated the fetal origins phenomenon in Yucatan miniature swine, we hypothesized that sulfur amino acid metabolism is altered in IUGR piglets. In this study, metabolites and the activities of sulfur amino acid cycle enzymes were analyzed in liver samples of 3- to 5-day-old runt (IUGR: 0.85±0.13 kg) and large (1.36±0.21 kg) Yucatan miniature pig littermates (n=6 pairs). The IUGR piglets had significantly lower specific and total activities of betaine-homocysteine methyltransferase (BHMT) and cystathionine γ-lyase (CGL) than larger littermates (P<.05). Expression of CGL (but not BHMT) mRNA was also lower in IUGR piglets (P<.05). This low CGL reduced cysteine and taurine concentrations in IUGR pigs and led to an accumulation of hepatic cystathionine, with lower homocysteine concentrations. Methylation index and liver global DNA methylation were unaltered. Reduced prenatal growth in Yucatan miniature piglets impairs their remethylation capacity as well as their ability to remove cystathionine and synthesize cysteine and taurine, which could have important implications on long-term health outcomes of IUGR neonates.
