Economic Burden of Avoidable Hospitalizations among Patients with Cancer at Namazi Hospital in Shiraz, 2013

Potentially Avoidable Admissions and Prolonged Hospitalization in Patients with Suspected Colon Cancer

BACKGROUND

Suspicion of cancer in the Emergency Department (ED) may lead to potentially avoidable and prolonged admissions. We aimed to examine the reasons for potentially avoidable and prolonged hospitalizations after admissions from the ED for new colon cancer diagnoses (ED-dx).

METHODS

A retrospective, single-institution analysis was conducted of patients with ED-dx between 2017 and 2018. Defined criteria were used to identify potentially avoidable admissions. Patients without avoidable admissions were examined for ideal length of stay (iLOS), using separate defined criteria. Prolonged length of stay (pLOS) was defined as actual length of stay (aLOS) being greater than 1 day longer than iLOS.

RESULTS

Of 97 patients with ED-dx, 12% had potentially avoidable admissions, most often (58%) for cancer workup. Very little difference in demographic, tumor characteristics, or symptoms were found, except patients with potentially avoidable admissions were more functional (Eastern Cooperative Oncology Group [ECOG] score 0-1: 83% vs. 46%; p = 0.049) and had longer symptom duration prior to ED presentation {24 days (interquartile range [IQR] 7-75) vs. 7 days (IQR 2-21)}. Among the 60 patients who had necessary admissions but did not require urgent intervention, 78% had pLOS, most often for non-urgent surgery (60%) and further oncologic workup. The median difference between iLOS and aLOS was 12 days (IQR 8-16) for pLOS.

CONCLUSIONS

Potentially avoidable admissions following Ed-dx were uncommon but were mostly for oncologic workup. Once admitted, the majority of patients had pLOS, most often for definitive surgery and further oncologic workup. This suggests a lack of systems to safely transition to outpatient cancer management.

Potentially Avoidable Hospital Readmissions in Patients With Advanced Cancer

PURPOSE

Patients with cancer often prefer to avoid time in the hospital; however, data are lacking on the prevalence and predictors of potentially avoidable readmissions (PARs) among those with advanced cancer.

METHODS

We enrolled patients with advanced cancer from September 2, 2014, to November 21, 2014, who had an unplanned hospitalization and assessed their patient-reported symptom burden (Edmonton Symptom Assessment System) at the time of admission. For 1 year after enrollment, we reviewed patients' health records to determine the primary reason for every hospital readmission and we classified readmissions as PARs using adapted Graham's criteria. We examined predictors of PARs using nonlinear mixed-effects models with binomial distribution.

RESULTS

We enrolled 200 (86.2%) of 232 patients who were approached. For these 200 patients, we reviewed 277 total hospital readmissions and identified 108 (39.0%) of these as PARs. The most common reasons for PARs were premature discharge from a prior hospitalization (30.6%) and failure of timely follow-up (28.7%). PAR hospitalizations were more likely than non-PAR hospitalizations to experience symptoms as the primary reason for admission (28.7% v 13.0%; P = .001). We found that married patients were less likely to experience PARs (odds ratio, 0.30; 95% CI, 0.15 to 0.57; P < .001) and that those with a higher physical symptom burden were more likely to experience PARs (odds ratio, 1.03; 95% CI, 1.01 to 1.05; P = .012).

CONCLUSION

We observed that a substantial proportion of hospital readmissions are potentially avoidable and found that patients' symptom burdens predict PARs. These findings underscore the need to assess and address the symptom burden of hospitalized patients with advanced cancer in this highly symptomatic population.
