Hospital Teaching Status Impacts Surgical Discharge Efficiency

Area of Science:

• Health Services Research
• Surgical Outcomes
• Hospital Efficiency

Background:

• Graduate medical education emphasizes systems-based practice and care transitions.
• Data on the efficiency of care in teaching hospitals is limited.
• Understanding discharge efficiency is crucial for optimizing patient flow and resource utilization.

Purpose of the Study:

• To investigate the association between hospital teaching status and discharge efficiency in surgical services.
• To determine if teaching hospitals (TH) or nonteaching hospitals (NTH) are more efficient in discharging surgical patients.
• To identify potential differences in care pathways that influence discharge timing.

Main Methods:

• Analysis of 272,090 general surgery patients from the 2012 Healthcare Cost and Utilization Project National Inpatient Sample.
• Stratification of patients by hospital teaching status (TH vs. NTH).
• Definition of procedure-specific early discharge (PSED) as discharge within the lowest 25th percentile of length of stay.
• Multivariable mixed-effects logistic regression to assess the association between teaching status and PSED, adjusting for confounders and complications.

Main Results:

• Teaching hospital status was associated with significantly lower PSED rates (10.7% in TH vs. 11.4% in NTH; p < 0.001).
• Patients at TH had a longer average length of stay (5.5 days vs. 4.5 days in NTH; p < 0.001).
• Adjusted analysis revealed TH patients were 8% less likely to achieve PSED (OR 0.92; p < 0.002).

Conclusions:

• Teaching hospital status correlates with a reduced likelihood of procedure-specific early discharge.
• The impact of teaching status on discharge efficiency varied across different surgical procedure subgroups.
• Investigating discharge practices at nonteaching hospitals could reveal efficient care models applicable system-wide.
