PMID 35671438WHAT IT FOUND
Nearly 30% of oncology patients experienced persistent, high-severity nausea for two months despite antiemetics.
These patients also reported more vomiting, diarrhea, and weight loss. Younger age, lower income, and poorer physical function were linked to this high-risk profile.
Key findings
01A latent class analysis identified four distinct nausea profiles: none (40.8%), decreasing (8.9%), increasing-decreasing (21.5%), and high (28.8%).
02Patients in the high nausea class reported significantly higher frequency, severity, and distress of nausea compared to other classes, alongside higher rates of vomiting, diarrhea, and weight loss.
03Membership in the high nausea class was associated with younger age, lower annual household income, child care responsibilities, and lower physical function scores.

What it does not show
The study did not assess adherence to antiemetic medications, so it is unclear if the high nausea rates were due to ineffective prescriptions or patients not taking them. Data on as-needed antiemetics taken at home were not collected, potentially underestimating the total symptom burden or management efforts. The study did not include patients who refused participation because they were overwhelmed by treatment, which may bias the sample. Chemotherapy regimens were highly heterogeneous, preventing analysis of specific drug effects on nausea profiles.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that prescribing stronger antiemetics alone will resolve nausea for the high-risk group. This study shows that nearly 30% of patients had persistent, severe nausea despite receiving combination antiemetics, suggesting that non-pharmacologic factors like physical function, social stressors, and adherence play a significant role.
