Palliative medicine physicians’ experiences using the Numeric Rating Scale for pain assessment in patients with advanced cancer: a qualitative study

The study shows the complexity needed within palliative cancer care when using the most common pain assessment tool in Sweden, the NRS. The tool may seem simplistic, but, as shown in this study, the physicians found interpreting the assessments challenging for the whole team. This complexity should be incorporated into future healthcare education and training within the palliative care area, where patients often have chronic pain conditions in combination with cognitive impairment. Future research needs to focus on developing reliable pain assessment methods for patients who are cognitively impaired because of the cancer.
