Discharge Against Medical Advice in Cancer Patients: Insights from a Multicenter Study in Germany.

BACKGROUND

Discharge against medical advice (DAMA) disrupts continuity of care and is associated with increased readmission rates, morbidity, and mortality. While extensively studied in general hospital populations, its prevalence and associated factors in cancer patients, where treatment adherence is critical for outcomes, remain underexplored.

METHODS

This multicenter, cross-sectional study analyzed anonymized data from the IQVIA hospital database, including cancer patients hospitalized in 36 German hospitals between January 2019 and December 2023. Multivariate logistic regression assessed associations between DAMA and factors such as age, sex, cancer type, metastases, and comorbidities.

RESULTS

Among 51,505 cancer patients, DAMA occurred in 0.9% of hospitalizations. The highest rates were observed in cancers of the lip, oral cavity, and pharynx (2.1%), larynx (2.0%), and liver (1.8%). DAMA was more frequent in younger patients (≤50 years) (OR: 1.73; 95% CI: 1.30-2.14) and males (OR: 1.46; 95% CI: 1.23-1.72). Distant metastases showed no significant association (OR: 0.96; 95% CI: 0.81-1.13).

CONCLUSIONS

The findings suggest that DAMA in cancer patients is more strongly associated with demographic and social factors than with disease severity. These results provide a basis for exploring strategies that address underlying psychosocial and economic challenges during hospitalization, particularly in younger and male patients. Further research is needed to better understand these associations and their implications for clinical practice.
