AB0801 TIME FOR REFERRAL AND DEFINITIVE DIAGNOSIS IN PATIENTS WITH HAND ARTHRALGIA

Abstract

Background:Early referral of patients with suspicion of progression to rheumatoid arthritis (RA) is of paramount importance in disease prognosis. We had previously described a time delay of 28 months between symptom onset and evaluation by a rheumatologist, and a mean wait time of 9.5 weeks for referral to a secondary-level public hospital (1). The availability of specialized interdisciplinary evaluation of patients in a third-level of care raises the possibility of shortening this time gap, as well as describing patient and physician decisions amidst the referral to a Rheumatology center.Objectives:Describe the diagnosis profile of patients with hand arthralgia and time of referral to Rheumatology in a Family Medicine clinic.Methods:A cohort study was conducted in 110 patients from October 2018 to December 2020 in a Family Medicine clinic within the tertiary-care University Hospital “Dr. Jose Eleuterio Gonzalez” in Monterrey, Mexico. Patients with hand arthralgia as their chief complaint were recruited. An observational, descriptive compilation of patient history was retrieved prospectively through medical records. Variables included time of inclusion, number of medical visits until referral and definitive diagnosis. Descriptive statistics, Kaplan-Meier curves and log-rank tests were used to test the association between time of diagnosis and clinical variables of interest.Results:Assessed variables are shown in Table 1. Out of 110 patients with hand arthralgia, a quarter received a final diagnosis within 3 medical visits. Less than half of patients were referred, and only a third attended the referral indication. It takes 39.3 days from the first medical visit to be referred, and 69 days and 2.89 consultations to receive a definitive diagnosis. Around half of patients will have a definitive diagnosis, osteoarthritis being the most common. The log-rank test for categoric variables including a positive squeeze test or ≥4 criteria of clinically suspect arthralgia did not show a significant association for time of referral and definitive diagnosis (data not shown).Table 1.Diagnostic and referral characteristics of patients with hand arthralgia attending a Family medicine clinicPatients recruited in a Family Medicine clinicn = 110Female, n (%)90 (81.8)Age in years, mean ± SD49.69 ± 14.90RF, ACPA, or hand radiography request, n (%)100 (90.9)Diagnosis in Family MedicineDiagnosed patients after 1 medical visit, cumulative n (%)5 (4.6)Diagnosed patients after 2 medical visits, cumulative n (%)22 (20.0)Diagnosed patients after 3 medical visits, cumulative n (%)26 (23.6)Referral to Rheumatology for diagnostic doubt or clinical follow-upPatients referred to a Rheumatology clinic, n (%)49 (44.5)Patients attending Rheumatology referral, n (%)34 (30.9)Time for referral, days ± SD39.37 ± 38.64Global definitive diagnosisPatients with a definitive diagnosis, n (%)51 (46.4)Osteoarthritis diagnosis, n (%)23 (20.9)Rheumatoid arthritis diagnosis, n (%)13 (11.8)Overlap syndrome diagnosis, n (%)5 (4.5)Time for definitive diagnosis, days ± SD68.96 ± 106.57Number of consultations for definitive diagnosis, mean ± SD2.86 ± 1.05RF, rheumatoid factor; ACPA, anticitrullinated protein antibodies; SD, standard deviation.Conclusion:Patients with hand arthralgia evaluated in a tertiary-care Rheumatology center receive a timely referral in one month and a definitive diagnosis after 3 medical visits in around two months.References:[1]Vega-Morales, D., Covarrubias-Castañeda, Y., Arana-Guajardo, A.
