Overcoming barriers to opioid-induced constipation management in cancer patients

Opioid-induced constipation (OIC) is a common adverse effect of opioid therapy. We aim to identify the main barriers hindering clinical recommendations implementation and propose consensus solutions to improve OIC control in cancer patients.

Following collaborative and prioritization techniques, a scientific committee generated statements addressing possible barriers to optimal OIC management (related to patients, health providers and health care system), and potential interventions to overcome these barriers. An expert panel of 36 oncologists assessed the statements to reach a consensus.

The survey consisted of 70 statements. Consensus was reached on 12/45 items related to barriers (26.6%) and on 19/25 items about corrective interventions (76%). The panel considered that patients are unaware of the existence of a specific OIC treatment, and their information sources are highly variable and unreliable. Regarding health providers, the panel considered that the oncologists prioritize symptoms such as diarrhea, pain, anxiety, or other treatment toxicities, over constipation. Work overload and bureaucratic requirements were the main barriers related to health care system. Regarding potential interventions, best-rated proposals included specific training programs development for primary care physicians and nurses, and multiplatform informative resources development for patients and caregivers, including precisely written instructions about OIC recognition and management. Oncologists assessed positively measures aiming to improve coordination between primary care physicians and oncologists, and nursing consultations implementation. The panel considered useful the OIC treatment algorithms simplification.

The expert panel identified the main barriers to optimal OIC management and suggested some feasible approaches to overcome these barriers.
