Current Difficulties for General Practitioners in the Diagnosis and Management of Long COVID Patients: A Cross-Sectional Study Assessing an Online Questionnaire

Background: Long COVID presents a novel and emerging public health challenge. As the first point of contact, general practitioners (GPs) play a key role in diagnosing and coordinating the care of patients presenting with post-acute sequelae of COVID-19 (PASC), despite a lack of experience. This study aimed to identify the main difficulties encountered by GPs in Franche-Comté, France, in managing adult outpatients with long COVID. Methods: We conducted a cross-sectional survey using an anonymous online questionnaire, which contained 21 questions and was distributed to GPs in Franche-Comté, France. The survey assessed definition, diagnostic and therapeutic challenges in managing long COVID. Results: Among the 410 questionnaires distributed, 90 general practitioners (GPs) responded (response rate: 21.9%). The mean age of participants was 34 ± 10 years, and 64.4% were women (n = 58). Regarding knowledge of long COVID, three participants (3.3%) did not recognize it as a distinct clinical entity, while more than half (58.9%, n = 53) reported insufficient knowledge. The main challenges identified were therapeutic management (76.7%, n = 69) and diagnosis (75.6%, n = 68). Only 4.5% of respondents (n = 4) reported no difficulty in defining post-acute sequelae of SARS-CoV-2 infection (PASC). The most frequently reported diagnostic difficulty was distinguishing long COVID from differential diagnoses (93.3%, n = 83/89), particularly fibromyalgia (94.3%, n = 83/88). Only 37.1% of participants (n = 33/89) reported actively following up patients with PASC. During initial management, the main challenge was the difficulty in objectively assessing patients’ complaints using available diagnostic tools (80.7%, n = 67/83). Additionally, a large majority of GPs reported difficulties in addressing patients’ questions (86.7%, n = 72/83) and managing associated anxiety disorders (75.9%, n = 63/83). Conclusions: These findings highlight the immediate need to enhance GP training in Franche-Comté, France, in dealing with long COVID. Improvements such as harmonizing long COVID definitions, testing diagnoses, and strengthening interdisciplinary coordination are essential to provide coherent and patient-centered care for this disease.
