[Appropriateness of requests for urgent outpatient cardiological services and impact on waiting lists: the experience of the Azienda Socio-Sanitaria Territoriale of the Province of Lodi].

Background: The Cardiology Complex Structure of the Azienda Socio Sanitaria Territoriale (ASST) of Lodi, Italy, assists patients with clinical conditions ranging from emergency to chronicity. The model of Homogeneous Waiting Groups should guide the appropriateness of prescriptions categorized as U (urgent), B (brief), D (deferrable), and P (programmable). This study aims to describe and analyze the characteristics of prescription and delivery of clinical and instrumental cardiology outpatient services with U and B priority during the November 2023-January 2024 quarter, paying particular attention to the clinical appropriateness of prescribing.

Methods: A prospective observational study was conducted. Computerized data were anonymously extracted from the company's Management Control and provided with the authorization of the Data Protection Officer.

Results: During the observed quarter, the Cardiology Complex Structure provided 7379 services for outpatients. Out of 123 U services, 94 (76.4%) were managed through SBC (Single Booking Center) and 29 (23.6%) were managed outside the SBC. From 529 services with B priority, 504 (95%) were managed through SBC and 25 (5%) outside the SBC. Requests with U priority mainly referred to ECG (n = 50; 40.6%) and first cardiological visit (n = 46; 37.4%). Fifty percent of U and B requests were prescribed by 4% and 8% of general practitioners, respectively. The prescribed priority was correct for 13% of requests (n = 64).

Conclusions: This study shows a vastly inappropriate use of resources allocated to urgent outpatient cardiological services. Actions aimed at promoting the adherence to the Homogeneous Waiting Groups Manual and enhancing telemedicine services, currently limited to heart failure, are necessary for resource optimization in cardiology within the ASST of Lodi.
