ABSTRACT
Objectives Numerous previous studies investigated the impact of medical training settings on outcomes of hospitalized patients. However, the impact of teaching hospital status on outcomes of percutaneous paracentesis, to the best of our knowledge, has never been studied before. Methods Hospitalized patients who underwent percutaneous paracentesis were identified from the National Inpatient Sample database from 2016 to 2019 across the United States (US) teaching and non-teaching hospitals. Outcomes studied were differences in risk of mortality, postprocedural outcomes, and healthcare resource utilization. Multivariate logistic analysis was performed using STATA software (StataCorp LLC, College Station, Texas, US) and results were adjusted for patient and hospital characteristics and comorbidities. Results Inpatient mortality rates were significantly higher in patients undergoing paracentesis at US teaching hospitals (adjusted odds ratio (aOR) 1.29, 95%CI 1.23-1.35, p<0.001) compared to non-teaching hospitals. Similarly, higher risk of procedural complications including hemoperitoneum (aOR 1.90, 95%CI 1.65-2.20, p<0.001), hollow viscus perforation (aOR 1.97, 95%CI 1.54-2.51, p<0.001), and vessel injury/laceration (aOR 15.3, 95%CI 2.12-110.2, p=0.007) were noticed in the study group when compared to controls. Furthermore, hospital teaching status was associated with prolonged mean length of stay (9.33 days vs 7.42 days, adjusted mean difference (aMD) 1.81, 95%CI 1.68-1.94, p<0.001) and increased charge of care ($106,014 vs $80,493, aMD $24,926, 95%CI $21,617-$28,235, p <0.001) Conclusion Hospitalized patients undergoing paracentesis in US teaching hospitals have an increased risk of mortality, postprocedural complications, prolonged length of stay, and increased charge of care when compared to non-teaching hospitals.
