Rationale: People living with and beyond cancer (PLWBC) often use healthcare resources extensively. We aimed to assess the association between annualized rates of specific healthcare visits and phase angle (PhA), accounting for time-at-risk and clinical confounders.

Methods: Cross-sectional analysis of 105 PLWBC (≥18 years), disease-free (>3 months to <5 years since last treatment), mainly breast and colorectal cancer. Medical visits from diagnosis to study entry were extracted from electronic medical records and annualized (visits/year) in four categories: emergency, hospital admissions, outpatient, and primary care. Phase angle (PhA) at 50 kHz was assessed using bioelectrical impedance analysis (BIA; InBody 770). Multivariable linear regression evaluated associations between visit rates and PhA, adjusted for age, sex, body mass index (BMI), comorbidities, chemotherapy, radiotherapy, and physical activity.

Results: Mean age was 59.1±12.0 years (63% women). Higher annualized emergency visits were independently linked to lower PhA (β=-0.095; 95% CI: -0.182 to -0.009; p=0.031). No significant associations were observed for hospital admissions, outpatient visits, or primary care (Table).

Conclusion: Higher annualized emergency visit rates are linked to lower phase angle in PLWBC, even after adjusting for clinical factors. While causality cannot be established due to the cross-sectional design, acute healthcare resource use may indicate physiological vulnerability. More research is needed to determine if this could help identify patients for targeted nutritional assessment.
