Overview
The aim of this study is to investigate the pharmacological treatment pattern among patients with diabetic peripheral neuropathic pain (DPNP) and chemotherapy-induced peripheral neuropathy (CIPN) in China.
Description
Diabetic peripheral neuropathic pain (DPNP) and chemotherapy-induced peripheral neuropathy (CIPN) are common subtypes of neuropathic pain. The treatment pattern, subsequent medication usage, and adherence information of medication among these patients are still not clear. There is also an unmet need for the use of relevant analgesic medications in this area. This real-world data study aims to understand patients' characteristics, clinical diagnosis and treatment patterns, medication adherence, real-world effectiveness among DPNP and CIPN patients in China and will explore the current unmet needs of DPNP and CIPN, in order to inform physicians' decision-making in clinical practice

Participants who meet all the following criteria will be included in the CIPN cohort.
- Participants had neuropathy that was induced by the chemotherapy between 1st January 2018 and 31st December 2021, regardless of the presence of pain symptoms;
- Participants received at least one targeted medication between 1st January 2018 and 31st December 2021;
