Medical Observation Units and Emergency Department Collaboration: Improving Patient Throughput

Reducing Hospitalization in Mild Acute Pancreatitis: Results of Long-term Follow-up

GOALS AND BACKGROUND

Acute pancreatitis (AP) is a common emergency department (ED) diagnosis, amounting to enormous costs. Our previous pilot study demonstrated the feasibility of reducing hospitalization using an ED-based observation pathway. In this follow-up study, we hypothesize that the pathway is durable in clinical practice, outside of research supervision, and patients can safely be managed without hospitalization.

STUDY

We reviewed patients prospectively enrolled in the observation pathway after the end of the pilot study. We compared outcomes to patients enrolled in our pilot study and with a historic cohort of patients admitted with mild AP. Our primary outcome was hospitalization rate during the enrollment period and secondary outcomes included length of stay, 30-day readmissions, mortality, and health care utilization.

RESULTS

Over a 2-year period 165 patients met criteria for AP with 118 (71.5%) having mild AP. Fifty-four of 118 patients (45.8%) were enrolled in the observation pathway and of these, 45 patients were discharged from the ED, reducing hospitalization by 31.2%, compared with pilot study (22.2%) and historic cohort (0%) (P<0.05). Median length of stay was shorter [19.9 (observation) vs. 72.0 h (historic cohort), P<0.01]. There were fewer radiographic examinations in the observation cohorts (pilot and current study) than in the historic cohort (P<0.05), with similar 30-day readmissions, and no reported deaths.

CONCLUSIONS

This follow-up study demonstrates the durability of an observation-based pathway to manage mild AP outside of a research protocol and maintain its ability to reduce hospitalizations without affecting readmission rates or mortality.

Triage to Observation: A Quality Improvement Initiative for Chest Pain Patients Presenting to the Emergency Department

OBJECTIVE

The objective of this study was to evaluate the impact of a rapid admission protocol for chest pain patients presenting to the emergency department (ED) on ED length-of-stay (LOS). In this study, ED LOS was defined as the time from triage check-in until the time the patient physically leaves the ED. The purpose of this quality improvement study was to decrease ED crowding.

METHODS

This is a single-center prospective cohort study performed as a quality improvement initiative. This study implemented a rapid admission protocol for patients who were at moderate risk for a major adverse cardiac event based on the HEART score. When a patient presented to the ED through triage with a chief complaint of chest pain, this protocol allowed the provider-in-triage (PIT) to identify eligible patients for potential rapid admission to the hospital's clinical decision unit (CDU). The PIT would complete a rapid medical screening examination, initiate the patient's workup, and call the CDU providers to further evaluate the patient. By identifying these patients early, the lengthy ED chest pain workup contributing to longer ED LOS could then be completed in the CDU.

RESULTS

The total number of patients seen in the ED over the study period was 34,251. The total number of patients admitted to the CDU during the study period was 1,442. The PIT identified 13 patients for rapid admission to the CDU during the study period. These patients had a statistically significant reduction in ED LOS (P < 0.001). ED LOS was also adjusted to identify delays in patient movement resulting in a statistically significant difference (P < 0.001).

CONCLUSION

Implementation of a rapid admission protocol for chest pain patients at moderate risk for a major adverse cardiac event resulted in a reduction in ED LOS. Adjusted ED LOS was also significant, highlighting a delay in patient movement from the ED to the CDU indicating continued barriers affecting ED holding times.

Incidence, Admission Rates, and Predictors, and Economic Burden of Adult Emergency Visits for Acute Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012

INTRODUCTION

Acute pancreatitis (AP) is the most common gastroenterology-related reason for hospital admission, and a major source of morbidity and mortality in the United States. This study examines the National Emergency Database Sample, a large national database, to analyze trends in emergency department (ED) utilization and costs, risk factors for hospital admission, and associated hospital costs and length of stay (LOS) in patients presenting with AP.

METHODS

The National Emergency Database Sample (2006 to 2012) was evaluated for trends in ED visits, ED charges, hospitalization rates, hospital charges, and hospital LOS in patients with primary diagnosis of AP (further subcategorized by age and etiology). A survey logistic-regression model was used to determine factors predictive of hospitalization.

RESULTS

A total of 2,193,830 ED visits were analyzed. There was a nonsignificant 5.5% (P=0.07) increase in incidence of ED visits for AP per 10,000 US adults from 2006 to 2012, largely driven by significant increases in ED visits for AP in the 18 to <45 age group (+9.2%; P=0.025), AP associated with alcohol (+15.9%; P=0.001), and AP associated with chronic pancreatitis (+59.5%; P=0.002). Visits for patients aged ≥65 decreased over the time period. Rates of admission and LOS decreased during the time period, while ED and inpatient costs increased (62.1%; P<0.001 and 7.9%; P=0.0011, respectively). Multiple factors were associated with increased risk of hospital admission from the ED, with the strongest predictors being morbid alcohol use [odds ratio (OR), 4.53; P<0.0001], advanced age (age>84 OR, 3.52; P<0.0001), and smoking (OR, 1.75; P<0.0001).

CONCLUSIONS

Despite a relative stabilization in the overall incidence of ED visits for AP, continued increases in ED visits and associated costs appear to be driven by younger patients with alcohol-associated and acute on chronic pancreatitis. While rates of hospitalization and LOS are decreasing, associated inflation-adjusted costs are rising. In addition, identified risk factors for hospitalization, such as obesity, alcohol use, and increased age, should be explored in further study for potential use in predictive models and clinical improvement projects.

Factors Related to School Nurse Workload

Recognizing the need for a school nurse workload model based on more than the number of students in a caseload, the National Association of School Nurses issued recommendations related to measuring school nurse workload. Next, a workforce acuity task force (WATF) was charged with identifying the steps needed to further the recommendations. As a first step, the WATF focused on identifying existing literature and practices related to school nurse workload. The purpose of this article is to synthesize and categorize the factors that were identified, delineate sources for collecting and retrieving these factors, and make recommendations for clinicians and researchers interested in developing instruments to measure school nurse workload.
