Background: Patients with cancer in Canada are often effectively managed in ambulatory settings; however, patients with unmanaged or complex symptoms may turn to the emergency department (ED) for additional support. These unplanned visits can be costly to the healthcare system and distressing for patients. This study used a novel patient-reported outcomes (PROs)-derived symptom complexity algorithm to understand characteristics of patients who use acute care, which may help clinicians identify patients who would benefit from additional support., Patients and Methods: This retrospective observational cohort study used population-based linked administrative healthcare data. All patients with cancer in Alberta, Canada, who completed at least one PRO symptom-reporting questionnaire between October 1, 2019, and April 1, 2020, were included. The algorithm used ratings of 9 symptoms to assign a complexity score of low, medium, or high. Multivariable binary logistic regressions were used to evaluate factors associated with a higher likelihood of having an ED visit or hospital admission (HA) within 7 days of completing a PRO questionnaire., Results: Of the 29,133 patients in the cohort, 738 had an ED visit and 452 had an HA within 7 days of completing the PRO questionnaire. Patients with high symptom complexity had significantly higher odds of having an ED visit (OR, 3.10; 95% CI, 2.59-3.70) or HA (OR, 4.20; 95% CI, 3.36-5.26) compared with low complexity patients, controlling for demographic covariates., Conclusions: Given that patients with higher symptom complexity scores were more likely to use acute care, clinicians should monitor these more complex patients closely, because they may benefit from additional support or symptom management in ambulatory settings. A symptom complexity algorithm can help clinicians easily identify patients who may require additional support. Using an algorithm to guide care can enhance patient experiences, while reducing use of acute care services and the accompanying cost and burden.

Background: Previous studies have found that patients with lung cancer report worse patient experience compared to other tumour groups. Reasons that may negatively impact patient experience include delays in diagnosis as well as inadequate symptom management. The purpose of this study was to compare the diagnostic timelines and symptom reports of patients with lung and gastrointestinal (GI) cancers., Methods: This study included patients diagnosed with lung or GI cancers who attended a radiation oncology (RO) consultation and/or received radiation treatment between May and August 2019 at the Tom Baker Cancer Centre, Calgary, Alberta, Canada. Data collected included demographics, dates of diagnostic time points, and self-reported symptom scores across 3 time points. A descriptive analysis was completed, and the median number of days between time points was compared between tumour groups., Results: Patients with lung cancer had longer diagnostic timelines compared to GI patients. The median number of days between the first investigative test and biopsy was 21 days longer for patients with lung cancer (p < 0.05). From RO consultation to the first treatment review appointment, 25% and 4% of lung and GI patients, respectively, reported worsening of symptoms. A greater proportion of lung patients reported worse symptom scores during treatment compared to GI patients. This varied by specific symptom., Conclusions: Patients with lung cancer experienced delays in receiving a diagnosis and worse symptom burden during radiation therapy in this study. We identified potential targets to improve patient experience., (© 2021. Crown.)

Breast cancer patients receiving adjuvant chemotherapy are at increased risk of acute care use. The incidence of emergency department (ED) visits and hospitalizations (H) have been characterized in other provinces but never in Alberta. We conducted a retrospective population-based cohort study using administrative data of women with stage I-III breast cancer receiving adjuvant chemotherapy. Rates of ED and H use in the 180 days following chemotherapy initiation were determined, and logistic regression was performed to identify risk factors. We found that 47% of women receiving adjuvant chemotherapy experienced ED or H, which compared favourably to other provinces. However, Alberta had the highest rate of febrile neutropenia-related ED visits, and among the highest chemotherapy-related ED visits. The incidence of acute care use increased over time, and there were significant institutional differences despite operating under a single provincial healthcare system. Our study demonstrates the need for systematic measurement and the importance of quality improvement programs to address this gap.
