Description and management of patients with anal fissure: insights on Italian primary care setting coming from real-world data

To describe patients with anal fissure (AF) and their management in primary care. Retrospective study using the Italian Longitudinal Patient Database on 18 + years old subjects with AF records during 'July 2016-June 2021' (selection period). Index Date (ID) was the first AF record during selection period. Sub-cohorts were defined by presence/absence of prescriptions on ID of the combination of topical nifedipine 0.3% and lidocaine 1.5% (NIF/LID). Patients' information on the 12-month period before (baseline) and after (follow-up) ID was analyzed. Subjects with AF were 8632: 14.0% had NIF/LID on ID. Mean age was 52 (+/- 17.2) years, there were more women in ' < 50 years' group, and more men in '50-70' one. Prevalences of pregnancy and immunodepression were around 5%; most common comorbidities were hypertension (29.6%) and heart disease (13.1%), while constipation and diarrhea were < 5%. Healthcare resources utilization (HRUs) increased during follow-up, but still few patients were prescribed NIF/LID (2.8%), other treatments for AF (10.3%), or proctological visits (7.7%). NIF/LID patients were younger (< 40 years people: 30.7% versus 23.9%; p value < 0.0001), and more likely to have constipation (4.3% versus 2.5%; p value < 0.001); patients without NIF/LID showed slightly higher prevalences of hypertension (30.0% versus 27.1%; p value: 0.039) and depression (4.0% versus**2.5%; p value: 0.009), and a little higher overall HRUs. Results show that general practitioners are used to manage AF. However, there is still a gap between guidelines' recommendations and actual management. Educational campaigns on common anal problems in primary care might help further improving AF management and optimizing HRUs.
