Expert Consensus Develops Multidisciplinary Pathway for Cancer Pain Management in Italy: A Delphi Study

Background: Cancer pain remains highly prevalent and undertreated despite established guidelines. In Italy, Law 38/2010 mandates systematic pain assessment, yet only 26% of clinicians routinely evaluate pain at each clinical visit, and fewer than one-quarter have received formal training in pain medicine or palliative care. A national multidisciplinary roundtable, convened in Rome in March 2025, formally identified four systemic gaps—insufficient education, fragmented care pathways, unclear professional roles, and challenges in implementing shared diagnostic and therapeutic pathways—and planned the development of a structured Delphi consensus. Methods: A Delphi consensus process was undertaken in accordance with CREDES guidelines. The Steering Committee, comprising representatives of six Italian scientific societies (AIRO, AIOM, AISD, Federdolore-SICD, SICP, ACD-SIAARTI) and a patient advocacy group (Fondazione Nora e Alberto Gentili), developed 15 clinical statements addressing pain assessment, management, referral criteria, monitoring, and documentation over five online meetings held between March and September 2025. Sixty-six Italian clinicians from various specialties were invited to participate; the survey was open from 1 October to 31 December 2025, with reminders every 10 days. Consensus was defined as ≥75% agreement (scoring 4 or 5 on a 5-point Likert scale). Results: Fifty-six clinicians completed the survey (response rate: 84.8%), representing medical oncology, radiation oncology, pain therapy, and palliative care specialties; individual statements were rated by 53–54 panelists, as skipping single items was permitted. All statements reached consensus in the first round (77.8–100%), precluding the need for a second voting round. Panelists’ qualitative comments informed minor wording refinements; substantial content was unchanged. Conclusions: The Delphi process produced a validated, multidisciplinary clinical pathway for cancer pain management in the Italian National Health System (NHS). The pathway establishes structured roles for the clinical reference physician and specialist consultants, objective decision thresholds for analgesic titration and referral, and minimum requirements for standardized pain documentation. These consensus-based statements provide actionable clinical guidance that may help address analgesic undertreatment and support the implementation of Law 38/2010 across Italian oncology centers.
