Objective: This study examined the clinical consequences of a discharge against medical advice (DAMA) among pneumonia patients recommended to be hospitalized in a general ward and identified the risk factors related to a revisit after DAMA.
Methods: This retrospective observational study included pneumonia patients who presented at a university hospital emergency department (ED) and were recommended to be hospitalized in a general ward between January 2017 and December 2019. A multivariate logistic regression analysis was performed to identify the risk factors related to a revisit after DAMA and mortality.
Results: In the ‘revisit after DAMA’ group, the mortality rate was higher than the ‘no DAMA admission’ group (6.9% vs.
2.1%, P=0.009). Among all admitted patients, DAMA was a risk factor for mortality (odds ratio [OR], 6.185; P=0.023). In the ‘revisit after DAMA’ group, sex (OR, 6.590; P=0.005), C-reactive protein (CRP) score (OR, 1.149; P=0.022), febrile symptoms (OR, 6.569; P=0.004), and dyspnea (OR, 5.480; P=0.002) were risk factors of revisit. Furthermore, in the ‘revisit after DAMA’ group, the CRP score of the 2nd ED visit was higher than that of the 1st ED visit (6.55±6.27 vs. 8.20 ±7.31, P=0.014).
Conclusion: This study shows that DAMA is one of the risk factors for mortality. When DAMA patients revisit, the severity of their pneumonia was observed to have increased.
