Risk factors for return to the emergency department and readmission in patients with hospital-diagnosed advanced lung cancer.
The objectives of this study were to examine the patterns of care and risk factors for subsequent acute care utilization among patients with hospital-diagnosed advanced lung cancer (ALC). Researchers identified patients with incident ALC from 2007-13 and an index hospitalization within 7 days of diagnosis in Surveillance, Epidemiology, and End Results-Medicare. Results showed that more than half of the incident ALC patients were hospitalized around the time of diagnosis; among those who survived to discharge, only 37% received systemic cancer treatment. Many patients experienced an early readmittance and most died within 6 months. The researchers conclude that such patients may benefit from increased access to palliative and other supportive care during hospitalization to prevent subsequent health care utilization.

Care fragmentation and mortality in readmission after surgery for hepatopancreatobiliary and gastric cancer: a patient-level and hospital-level analysis of the Healthcare Cost and Utilization Project administrative database.
This study investigates patient-level and hospital-level variables associated with the mortality difference at referral centers and, postoperatively, outside hospitals, in patients undergoing hepatopancreatobiliary (HPB) and gastric oncologic surgeries. Using HCUP data, findings showed that, for readmissions following HPB and gastric oncologic surgery, travel distance and timing were major determinants of care fragmentation. However, these variables were not associated with mortality, nor was annual hospital surgical volume after risk-adjustment.

Indications for readmission following mastectomy for breast cancer: an assessment of patient and operative factors.
In this study, the investigators examined the impact of patient and operative factors on 30-day hospital readmission following mastectomy for breast cancer. Using the 2011 HCUP California State Inpatient Database, they evaluated readmissions in adult women undergoing mastectomy for invasive, in situ, or history of breast cancer. The investigators found that surgical site infection and wound complications were the most common diagnoses requiring readmission and resulted in over half of readmissions in their study population at 30 days.

The fate of radical cystectomy patients after hospital discharge: understanding the black box of the pre-readmission interval.
This study looked at reasons why bladder cancer patients who had undergone radical cystectomy surgery were readmitted to the hospital within 30 days. A retrospective cohort study was conducted for patients from 2005 to 2012. Researchers found that fever or difficulty with eating or maintaining their weight had the highest chance of being readmitted. Patients who had a higher pain tolerance or had noninfectious wounds or urinary concerns were less likely to be readmitted.

The relationship of travel distance with cystectomy access and outcomes.
The objectives of this study was to evaluate the effect of differential distance on cystectomy receipt among patients with muscle-invasive bladder cancer (MIBC) and investigate the association between travel distance and cystectomy outcomes such as readmission. The investigators found that the additional distance needed to reach a cystectomy provider did not predict receipt of surgery for MIBC. Furthermore, travel distance from cystectomy provider was not a significant predictor for subsequent readmission after cystectomy and did not affect overall survival.

Postoperative care fragmentation and thirty-day unplanned readmissions after head and neck cancer surgery.
Researchers sought to determine the frequency, risk factors, and outcomes for head and neck cancer patients experiencing postdischarge care fragmentation. They found that postdischarge care fragmentation following head and neck cancer surgery is common, as 37 percent of readmitted patients and 31 percent of patients readmitted with a treatment complication are readmitted to a hospital other than the surgical hospital.
