Simplified risk prediction indices do not accurately predict 30-day death or readmission after discharge following colorectal surgery.
This study examined the performance of widely used risk prediction indices to predict 30-day death or readmission after discharge following colorectal surgery. The study used a retrospective split-sample cohort of patients discharged after colorectal surgery from inpatient databases of HCUP for the states of New York, California, and Florida from 2006-2014. The commonly used risk prediction model LACE (length of stay, acute admissions, Charlson comorbidity index score, and emergency department visits) was compared with the real outcomes of death or readmission within 30 days after discharge with the cohort. Results showed a poor model fit with LACE and the researchers recommended a better model be developed.

30-day hospital readmission following otolaryngology surgery: analysis of a state inpatient database.
Researchers sought to determine patient and hospital-level risk factors associated with 30-day readmission for patients undergoing inpatient otolaryngologic surgery. Approximately one out of 12 patients undergoing otolaryngologic surgery had a 30-day readmission. Readmissions occur across a variety of types of procedures and hospitals. Most of the variability was driven by patient-specific factors, not structural hospital characteristics.

Cataract surgery complications and revisit rates among three states.
The authors studied cataract procedures from California, Florida, and New York, to characterize population-based 30-day procedure-related readmissions following surgery. Their results highlight the importance of age as a risk factor for cataract surgery readmissions, and suggest a relationship between black or Hispanic race, Medicaid insurance, and diabetes associated with higher risk for cataract surgery complications.
