The objective of our study was to describe knowledge, attitudes and practices of Latin-American rheumatology patients regarding management and follow-up of their disease during COVID-19 pandemic. A cross-sectional observational study was conducted using a digital anonymous survey. Rheumatic patients ≥ 18 years from non-English-speaking PANLAR countries were included. Our survey included 3502 rheumatic patients living in more than 19 Latin-American countries. Median age of patients was 45.8(36-55) years and the majority (88.9%) was female. Most frequently self-reported disease was rheumatoid arthritis (48.4%). At least one anti-rheumatic treatment was suspended by 23.4% of patients. Fear of contracting SARS-Cov2 (27.7%) and economic issues (25%) were the most common reasons for drug discontinuation. Self-rated disease activity increased from 30 (7-50) to 45 (10-70) points during the pandemic. Communication with their rheumatologist during the pandemic was required by 55.6% of patients, mainly by telephone calls (50.2%) and social network messages (47.8%). An adequate knowledge about COVID-19 was observed in 43% of patients. Patients with rheumatic diseases in Latin America were negatively affected by the COVID-19 pandemic. An increase in self-rated disease activity, a reduction in medication adherence, and hurdles for medical follow-up were reported. Teleconsultation was perceived as a valid alternative to in-person visits during the pandemic., (© 2021.

Background: Rheumatic diseases are a reason for frequent consultation with primary care doctors. Unfortunately, there is a high percentage of misdiagnosis., Objective: To design an algorithm to be used by primary care physicians to improve the diagnostic approach of the patient with joint pain, and thus improve the diagnostic capacity in four rheumatic diseases., Methods: Based on the information obtained from a literature review, we identified the main symptoms, signs, and paraclinical tests related to the diagnosis of rheumatoid arthritis, spondyloarthritis with peripheral involvement, systemic lupus erythematosus with joint involvement, and osteoarthritis. We conducted 3 consultations with a group of expert rheumatologists, using the Delphi technique, to design a diagnostic algorithm that has as a starting point "joint pain" as a common symptom for the four diseases., Results: Thirty-nine rheumatologists from 18 countries of Ibero-America participated in the Delphi exercise. In the first consultation, we presented 94 items to the experts (35 symptoms, 31 signs, and 28 paraclinical tests) candidates to be part of the algorithm; 74 items (25 symptoms, 27 signs, and 22 paraclinical tests) were chosen. In the second consultation, the decision nodes of the algorithm were chosen, and in the third, its final structure was defined. The Delphi exercise lasted 8 months; 100% of the experts participated in the three consultations., Conclusion: We present an algorithm designed through an international consensus of experts, in which Delphi methodology was used, to support primary care physicians in the clinical approach to patients with joint pain. Key Points • We developed an algorithm with the participation of rheumatologists from 18 countries of Ibero-America, which gives a global vision of the clinical context of the patient with joint pain. • We integrated four rheumatic diseases into one tool with one common symptom: joint pain. It is a novel tool, as it is the first algorithm that will support the primary care physician in the consideration of four different rheumatic diseases. • It will improve the correct diagnosis and reduce the number of paraclinical tests requested by primary care physicians, in the management of patients with joint pain. This point was verified in a recently published study in the journal Rheumatology International (reference number 31).

The aim of this study was to determine the prevalence of musculoskeletal pain and rheumatic diseases in subjects over 18 years of age from the canton of Cuenca, Ecuador. Cross-sectional analytical community-based study was conducted in subjects over 18 years of age using the validated Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) questionnaire. Random sampling was used. The questionnaire was administered by standardized health workers. Subjects were visited house by house. Subjects positive for musculoskeletal (MSK) pain in the last 7 days and at some point in life were assessed by rheumatologists to confirm the diagnosis. A total of 4877 subjects participated, with an average age of 42.8 (SD 18.8) years of age; 59.7 % were women; 69.7 % lived in urban areas. 32.5 % reported MSK pain in the last 7 days and 45.7 % at some point in life. The prevalence of knee osteoarthritis was 7.4 %, hand osteoarthritis 5.3 %, low back pain 9.3 %, rheumatoid arthritis 0.8 %, fibromyalgia 2 %, gout 0.4 %, and lupus 0.06 %. Subjects from rural areas reported experiencing more MSK pain in the last 7 days and at some point in life, lower income, poorer health-care coverage, and increased physical activity involving repetitive tasks such as lifting weights or cooking with firewood. MSK pain prevalence was high. Osteoarthritis and low back pain were the most common diseases. Age, sex, physical activity, repetitive tasks, living in a rural area, and lack of health-care coverage were found to be associated with MSK pain.

Objective: To assess the prevalence of musculoskeletal (MSK) pain and rheumatic diseases in the southeastern Mexican state of Yucatán., Methods: Using the Community Oriented Program in the Rheumatic Diseases (COPCORD) methodology, we performed a door-to-door, cross-sectional study generated through a multistage, stratified, randomized method on 3915 adult residents (age 42.7 ± 17.1 yrs; women 61.8%; urban setting 45.7%) of the Mexican state of Yucatán. We used universally accepted criteria for the diagnosis or classification of rheumatoid arthritis (RA), osteoarthritis (OA; knee and hand), fibromyalgia, systemic lupus erythematosus (SLE), gout, ankylosing spondylitis, regional rheumatic pain syndromes, and inflammatory back pain., Results: Nontraumatic MSK pain in the last 7 days was present in 766 (19.6%; 95% CI 18.3-20.8) individuals. MSK pain was more prevalent in women (26.6%) versus men (12.2%; p < 0.01). Self-reported MSK disability occurred in 1.7%. Most MSK pain-related variables were consistently more prevalent in the urban setting. The prevalence of rheumatic disease was: OA 6.8% (95% CI 6.0-7.6); back pain 3.8% (95% CI 3.2-4.4); RA 2.8% (95% CI 2.2-3.3); rheumatic regional pain syndromes 2.3% (95% CI 1.9-2.8); inflammatory back pain 0.7% (95% CI 0.5-1.0); fibromyalgia 0.2% (95% CI 0.1-0.4); gout 0.1% (95% CI 0.07-0.3); and SLE 0.07% (95% CI 0.01-0.2)., Conclusion: The prevalence of MSK pain was 19.6%. MSK pain was more prevalent in women and in the urban setting. A remarkably high prevalence of RA was found in this population, which suggests a role for geographic factors.

Objective: To estimate the prevalence of musculoskeletal (MSK) disorders and to describe predicting variables associated with rheumatic diseases in 5 regions of México., Methods: This was a cross-sectional, community-based study performed in 5 regions in México. The methodology followed the guidelines proposed by the Community Oriented Program for the Control of the Rheumatic Diseases (COPCORD). A standardized methodology was used at all sites, with trained personnel following a common protocol of interviewing adult subjects in their household. A "positive case" was defined as an individual with nontraumatic MSK pain of > 1 on a visual analog pain scale (0 to 10) during the last 7 days. All positive cases were referred to internists or rheumatologists for further clinical evaluation, diagnosis, and proper treatment., Results: The study included 19,213 individuals; 11,602 (68.8%) were female, and their mean age was 42.8 (SD 17.9) years. The prevalence of MSK pain was 25.5%, but significant variations (7.1% to 43.5%) across geographical regions occurred. The prevalence of osteoarthritis was 10.5%, back pain 5.8%, rheumatic regional pain syndromes 3.8%, rheumatoid arthritis 1.6%, fibromyalgia 0.7%, and gout 0.3%. The prevalence of MSK manifestations was associated with older age and female gender., Conclusion: The prevalence of MSK pain in our study was 25.5%. Geographic variations in the prevalence of MSK pain and specific diagnoses suggested a role for geographic factors in the prevalence of rheumatic diseases.

Objective: To estimate the prevalence, burden of illness, and help-seeking behavior of patients with musculoskeletal complaints and provide point prevalence estimates of osteoarthritis, low back pain, fibromyalgia, rheumatoid arthritis, gout, and bone fractures not related to trauma among the adult population in a urban community in Havana City., Methods: Home survey of adults validated against physical examination. Forty-eight trained family doctors and 3 rheumatologists supervised the interviews and confirmed diagnoses. Family doctors applied a validated Community Oriented Program for the Control of Rheumatic Diseases core questionnaire. A diagnosis using American College of Rheumatology criteria was established. Analysis was based on descriptive statistics and point prevalence estimates with 95% confidence intervals (CIs) of most common diseases and associated disability rate., Results: One thousand two hundred thirty-eight men and 1917 women were included. Prevalence of musculoskeletal pain was estimated in 43.9% (95% CI: 42.2-45.7). The knees were the most affected area (11.7%; 95% CI: 10.6-12) followed by low back pain (11.6%; 95% CI: 10.5-12.8). Point prevalence and 95% CI were as follows: osteoarthritis, 20.4% (95% CI: 19-21.8); gout, 0.38% (95% CI: 0.2-0.6); fibromyalgia, 0.22% (95% CI: 0.09-0.4); systemic lupus erythematosus, 0.06% (95% CI: 0.01-0.25); spondyloarthropathies, 0.19% (95% CI: 0.07-0.4); and rheumatoid arthritis,1.24% (95% CI: 0.8-1.7). Bone fractures not related to trauma were found in 1.14%, hip fracture being the most common (30.5%). Most patients were seen by the general practitioner (65.4%) and 6.2% described some disability., Conclusions: Musculoskeletal pain is highly prevalent in Cuba. Prevalence estimates are similar to those described in other surveys except for rheumatoid arthritis that seems more prevalent in Cuba and fibromyalgia less prevalent.
