There remains a knowledge gap in understanding patterns of symptoms that precede acute care events. Natural language processing (NLP) may enable greater understanding of the symptoms and identify differences across patient and cancer characteristics. Objective: To characterize symptoms preceding acute care in patients with cancer and quantify differences in symptom documentation across sociodemographic and cancer histologic subgroups. Design, Setting, and Participants: A cohort study in a single tertiary-care institution, including all acute care (emergency department and hospitalization) encounters for patients aged 18 years or older with a primary cancer diagnosis identified between January 1, 2013, and December 31, 2023. Main Outcomes and Measures: Natural language processing was used to identify routine clinical documentation to characterize symptoms documented in the 30 days preceding acute care. Logistic regression analyses was used to examine the possible association between sex, age, race and ethnicity, insurance coverage, cancer histologic characteristics, and reported symptoms. Results: Overall, 28 708 patients with cancer had 70 606 acute care visits with 854 830 associated preceding documented symptoms. Median age was 61 (IQR, 48-70) years. Men (37 861 encounters [53.62%]) and patients of White race (39 989 encounters [56.64%]) accounted for most acute care encounters. Pain (7.54% of documented symptoms), nausea (6.74%), and vomiting (5.79%) were the most frequently documented symptoms. Acute care encounters with patients who were female (adjusted odds ratio [AOR], 1.14; 95% CI, 1.10-1.18; P < .001), Asian (AOR, 1.22; 1.17-1.28; P < .001), Black (AOR, 1.17; 95% CI, 1.10-1.25; P < .001), American Indian or Alaska Native (AOR, 1.21; 95% CI, 1.01-1.44; P = .04), or Medicaid-insured (AOR, 1.10; 95% CI, 1.05-1.14; P < .001) were associated with a high documented symptom burden (>10 unique symptoms) preceding acute care visits. Patients aged 65 years or older (AOR, 0.96; 95% CI, 0.92-1.00; P = .04) or uninsured (AOR, 0.58; 95% CI, 0.45-0.76; P < .001) were less likely to have a high symptom burden documented before acute care events. Conclusions and Relevance: The findings of this study highlight common symptoms preceding acute care as well as the need for further research on interventions to reduce patient burden, improve quality of life, and reduce the use of acute care in patients with cancer.","journal":"JAMA Network Open","year":2025,"id":525574,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9626,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1297123,"name":"Jie Jane Chen","orcid":"0000-0002-5380-4825","position":1,"is_corresponding":false},{"id":51908,"name":"Jean Feng","orcid":"0000-0003-2041-3104","position":2,"is_corresponding":false},{"id":430294,"name":"Isabel D.
