The challenge of sustainability in healthcare systems: frequency and cost of diagnostic procedures in end-of-life cancer patients

Background: Literature data on the overuse and misuse of diagnostic procedures leading to end-of-life aggressiveness are scarce due to the limited amount of estimated economic waste. This study investigated the potential overuse of diagnostic procedures in a population of end-of-life patients. Methods: This is a retrospective study on consecutive advanced patients admitted into two Italian hospices. Frequency and relative costs of X-ray imaging, CT scans, MRI, and interventional procedures prescribed in the 3 months before admission were collected in patient electronic charts and/or in administrative databases. We conducted a deeper analysis of 83 cancer patients with a diagnosis of at least 1 year before admission to compare the number of examinations performed at two distant time periods. Results: Out of 541 patients, 463 (85.6%) had at least one radiological exam in the 3 months before last admission. The mean radiological exam number was 3.9 ± 3.2 with a relative mean cost of 278.60 ± 270.20 € per patient with a statistically significant (p < 0.001) rise near death. In the 86-patient group, a higher number of procedures was performed in the last 3 months of life than in the first quarter of the year preceding last admission (38.43 ± 28.62 vs. 27.95 ± 23.21, p < 0.001) with a consequent increase in cost. Conclusions: Patients nearing death are subjected to a high level of “diagnostic aggressiveness.” Further studies on the integration of palliative care into the healthcare pathway could impact the appropriateness of interventions, quality of care, and, ultimately, estimated costs.
