Conditions studied: Moderate to Severe Cancer Pain

In brief

This study is a multicenter cross-sectional observational study, aiming to include approximately 200 patients aged 18-75 years who are using hydrocodone sustained-release tablets or oxycodone sustained-release tablets for pain management of moderate to severe cancer pain. Baseline information, tumor history, and comorbidities of the subjects will be collected through electronic patient-reported outcomes (ePRO), and the pain condition will be evaluated using BPI, acute pain assessment tools, etc. Sleep-related indicators will be collected using Huawei smart wearable devices and PSQI, ISI scales. Psychological emotional states will be assessed using NCCN psychological distress thermometer, HAMA, HAMD, etc. Blood samples will also be collected for relevant tests. The study sets up a screening baseline assessment period, a 1-week assessment period, and 1-month and 3-month follow-up periods after enrollment. The changes in relevant indicators will be tracked throughout the process, aiming to quantify the association between pain and insomnia, anxiety and depression, and to verify the potential mediating role of sleep disorders between pain and emotional disorders, providing a basis for optimizing the comprehensive symptom management of cancer pain patients.
