Utilization and unexpected hospitalization rates of a pediatric emergency department 23-hour observation unit

Comparison of Length of Stay Between Children Admitted to an Observation Versus Inpatient Unit

OBJECTIVES

Many children who require hospitalization are ideal candidates for care in pediatric observation units (POUs) rather than inpatient pediatric units. Differences in outcomes between children cared for in these 2 practice settings have not been thoroughly evaluated.

METHODS

In this retrospective cohort study, children aged 0 to 18 years admitted to a POU at a community hospital or inpatient unit at a children's hospital were enrolled if they met specific clinical criteria. Information regarding the current illness, medical history, and hospital course was collected. Hospital length of stay (LOS) was analyzed as the primary outcome; secondary outcomes included conversion to inpatient care for the POU group and return to pediatric emergency department within 7 days. Subgroup analysis was conducted on children presenting with respiratory illnesses. Propensity scores were used as a predictor in the final model.

RESULTS

One hundred eighty-one admissions, 92 to POU and 89 to an inpatient unit, were analyzed. Mean LOS was 24.4 hours (95% confidence interval [CI], 21.7-27.1) for observation and 43.2 hours (95% CI, 37.8-48.6) for inpatient (P < 0.01). Among the 126 children admitted for respiratory illnesses, the mean LOS was 32.3 hours (95% CI, 26.0-38.6) for observation and 48.1 hours (95% CI, 42.2-54.0) for inpatient (P < 0.01). Survival analysis demonstrated a 1.61 (95% CI, 1.07-2.42) fold shorter time to discharge among children admitted to observation compared with inpatient (P = 0.02) and a 1.70 (95% CI, 1.07-2.71) fold shorter time to discharge from observation compared with inpatient for respiratory illnesses (P = 0.03). Within 7 days of discharge, 2 (2%) patients from the observation group and 1 (1%) from the inpatient group returned to the pediatric emergency department.

CONCLUSIONS

These findings suggest that POU may provide the means toward efficient care for children in community settings with illnesses requiring brief hospitalizations. Future work including prospective investigations is needed to ascertain the generalizability of these findings.

Utility of a pediatric observation unit for the management of children admitted to the emergency department

BACKGROUND

Observation Units (OU), as part of emergency department (ED), are areas reserved for short-term treatment or observation of patients with selected diagnoses to determine the need for hospitalization or home referral.

METHODS

In this retrospective cohort study, we analyzed similarities and differences of children admitted to the pediatric ED of the Fondazione Policlinico Universitario A. Gemelli IRCCS hospital in the first 2 years of OU activity, analyzing general patient characteristics, access modalities, diagnosis, triage, laboratory and instrumental examinations, specialist visits, outcome of OU admission and average time spent in OU. Furthermore, we compared total numbers and type of hospitalization of the first 2 years of OU activity with those of previous 2 years.

RESULTS

The most frequent diagnoses were abdominal pain, minor head injury without loss of consciousness, vomiting, epilepsy and acute bronchiolitis. The most performed laboratory examinations were blood count. The most commonly performed instrumental examination was abdominal ultrasound. Neurological counseling was the most commonly requested. Average time spent in OU was 13 h in 2016 and 14.1 h in 2017. Most OU admissions did not last longer than 24 h (90.5% in 2016 and 89.5% in 2017). In the years 2014-2015, 13.4% of pediatric patients accessing the ED were hospitalized, versus 9.9% the years 2016-2017 reducing pediatric hospital admissions by 3.6% (p <  0.001).

CONCLUSIONS

This study demonstrate that OU is a valid alternative to ordinary wards for specific pathologies. In accordance with the literature, our study showed that, in the first 2 years of the OU activity, admissions to hospital ward decreased compared with the previous 2 years with an increase of complex patients.

Can the Pediatric Early Warning Score (PEWS) Predict Hospital Length of Stay?

Background: Limited studies have evaluated the utility of scoring systems in the pediatric emergency department (PED) and no studies have evaluated their ability to predict hospital length of stay (LOS) and the usage of Observation units (OUs).

Objective: To evaluate the utility of the Pediatric Early Warning Score (PEWS) in predicting LOS in pediatric patients and thus anticipate admission to an OU versus the pediatric ward.

Methods: A retrospective study of pediatric inpatients (0 to 18 years) at an inner-city community hospital between January 2014 and December 2014. Patients with psychiatric illness, non-medical reasons for hospital stay, and those not discharged to ‘home’ were excluded. Demographic data, PEWS in the ED, and LOS for each patient were recorded and analyzed.

Results: A total of 719 patients were analyzed. PEWS range was 0 to 8. The mean LOS was 56.8 hours for patients with PEWS 0-1 compared to 62.7 hours for patients with PEWS ≥2 (p=0.02). There was a significant difference in PEWS for LOS ≤24 and ≤36 hours in comparison to those with LOS >24 hours and >36 hours, respectively (p<0.001). Overall, the PEWS correlated with LOS (r=0.11, p=0.002). Age correlated inversely with LOS (r=-0.16, p<0.001), without correlation to PEWS (r=-0.002, p= 0.96).

Conclusions: PEWS correlated weakly with LOS. A statistically significant lower PEWS was observed for patients who had short stays (both ≤24 and ≤36 hours) in comparison to those requiring longer inpatient care. Therefore, the PEWS is a useful tool to predict LOS and aid ED physicians to determine disposition, although further prospective studies in centers with OUs would better characterize its ability to suggest admission to an OU compared to the wards.

Managing Skin and Soft Tissue Infections in the Emergency Department Observation Unit

BACKGROUND

Skin and soft tissue infections (SSTIs) are a common reason for presentation to the emergency department (ED) and account for 3% of ED visits. Patients with a diagnosis of cellulitis requiring intravenous (IV) antibiotics have traditionally been admitted to the hospital. In our institution, these patients are placed in the ED Observation Unit (EDOU) for IV antibiotics.

OBJECTIVES

The purpose of this study is to determine if 3 doses of IV antibiotics are adequate to document clinical improvement in children with uncomplicated SSTI.

METHODS

A prospective cohort study of children aged 3 months to 18 years with uncomplicated SSTI admitted (2009-2013) to the EDOU at a children's hospital for IV antibiotics was conducted.

RESULTS

One hundred six patients (mean age, 68 months) were enrolled; 57% were boys, 53% of patients had cellulitis only and 47% had cellulitis with drained abscesses. There was a significant decrease in pain scores and size of cellulitis from arrival to discharge (P < 0.001 and P < 0.001, respectively). Eighty-three percent of patients were discharged after 3 to 4 doses of antibiotics, and 17% were admitted. The location of the wound, presence of systemic symptoms, and prior use of oral antibiotics did not predict admission in our study.

CONCLUSIONS

The EDOU is a reasonable alternative to inpatient admission in the management of patients with uncomplicated SSTI requiring IV antibiotics.

Reduced Emergency Department Utilization by Patients With Epilepsy Using QI Methodology

BACKGROUND

Epilepsy or seizure care is the most common neurologic condition that presents to an emergency department (ED) and accounts for a large number of annual cases. Our aim was to decrease seizure-related ED visits from our baseline of 17 ED visits per month per 1000 patients to 13.6 ED visits per month per 1000 patients (20%) by July 2014.

METHODS

Our strategy was to develop a quality improvement (QI) project utilizing the Institute for Healthcare Improvement model. Our defined outcome was to decrease ED utilization for children with epilepsy. Rate of ED visits as well as unplanned hospitalizations for epilepsy patients and associated health care costs were determined. A QI team was developed for this project. Plan do study act cycles were used with adjustments made when needed.

RESULTS

Nineteen months after implementation of the interventions, ED visits were reduced by 28% (from 17 visits per month per 1000 patients to 12.2 per month per 1000 patients) during the past year. The average number of inpatient hospitalizations per month was reduced by 43% from 7 admissions per month per 1000 patients to 4 admissions per month per 1000 patients. For both outcome measures, a 2-sample Poisson rate exact test yielded a P value < .0001. Health care claims paid were less with $115 200 reduction for ED visits and $1 951 137 reduction for hospitalizations.

CONCLUSIONS

Applying QI methodology was highly effective in reducing ED utilization and unplanned hospitalizations for children with epilepsy at a free-standing children's hospital.

Safely Discharging Infants with Bronchiolitis from an Emergency Department: A Five Step Guide for Pediatricians

Recent publications have established the pulse oxygen saturation (SpO₂) threshold of 90% for the hospitalization and discharge of infant patients with bronchiolitis. However, there is no clear recommendation regarding the Emergency Department (ED) observation period necessary before allowing safe home discharge for patients with SpO₂ above 90%-92%. Our primary aims were to evaluate the risk factors associated with delayed desaturation in infants with SpO₂ ≥ 92% on arrival at the ED as well as the ED observation period necessary before allowing safe home discharge. A secondary aim was to identify the risk factors for ED readmission. Of 581 episodes of bronchiolitis in patients < 1 year old admitted to the ED, only 47 (8%) had SpO₂ < 92% on arrival there, although 106 (18%) exhibited a delayed desaturation (to < 92%) during ED observation. Female sex, age < 3 months old, ED readmission, more severe initial clinical presentation, and higher pCO₂ level (> 6KPa) were risk factors for delayed desaturation with OR varying from 1.7 to 7.5. In patients < 3 months old, mean desaturation occured later than in older patients [6.0 hours (IQR 3.0–14.0) vs. 3.0 hours (IQR 2.0–6.0), P = 0.0018]. In 95% of patients with a delayed desaturation this decrease occurred within 25 hours for patients < 3 months old and within 11 hours for patients ≥ 3 months old. In patients < 3 months old with respiratory rates above the normal range for their age the desaturation occurred earlier than in patients < 3 months with normal respiratory rates [4.4 hours (IQR 3.0–11.7) vs. 14.6 hours (IQR 7.6–22.2), P = 0.037]. Based on the present study’s results, we propose a five step guide for pediatricians on discharging children with bronchiolitis from the ED. By using the threshold of an 11 hour ED observation period for patients ≥ 3 months old and a 25 hour period for patients < 3 months old we are able to detect 95% of the patients with bronchiolitis who are at risk of delayed desaturation.

Structure and Function of Observation Units in Children's Hospitals: A Mixed-Methods Study

OBJECTIVE

Observation unit (OU) use has been promoted recently to decrease resource utilization and costs for select patients, but little is known about the operations of pediatric OUs. This study aimed to characterize the infrastructure and function of OUs within freestanding children's hospitals and to compare characteristics between hospitals with and without OUs.

METHODS

All 43 freestanding children's hospitals that submit data to the Pediatric Health Information System were contacted in 2013 to identify OUs that admitted unscheduled patients from their emergency department (ED) in 2011. Semistructured interviews were conducted with representatives at hospitals with these OUs. Characteristics of hospitals with and without OUs were compared.

RESULTS

Fourteen (33%) of 43 hospitals had an OU during 2011. Hospitals with OUs had more beds and more annual ED visits compared to those without OUs. Most OUs (65%) were located in the ED and had <12 beds (65%). Staffing models and patient populations differed between OUs. Nearly 60% were hybrid OUs, providing scheduled services. OUs lacked uniform outcome measures. Themes included: admissions were intuition based, certain patients were not well suited for OUs, OUs had rapid-turnover cultures, and the designation of observation status was arbitrary. Challenges included patient discontent with copayments and payer-driven utilization reviews.

CONCLUSIONS

OUs were located in higher volume hospitals and varied by location, size, and staffing. Most functioned as hybrid OUs. OUs based admissions on intuition, had staffing cultures centered on rapid turnover of patient care, lacked consistent outcome measures, and faced challenges regarding utilization review and patient copayments.

Observation-status patients in children's hospitals with and without dedicated observation units in 2011

BACKGROUND

Pediatric observation units (OUs) have demonstrated reductions in lengths of stay (LOS) and costs of care. Hospital-level outcomes across all observation-status stays have not been evaluated in relation to the presence of a dedicated OU in the hospital.

OBJECTIVE

To compare observation-status stay outcomes in hospitals with and without a dedicated OU.

DESIGN

Cross-sectional analysis of hospital administrative data.

METHODS

Observation-status stay outcomes were compared in hospitals with and without a dedicated OU across 4 categories: (1) LOS, (2) standardized costs, (3) conversion to inpatient status, and (4) return care.

SETTING/PATIENTS

Observation-status stays in 31 free-standing children's hospitals contributing observation patient data to the Pediatric Health Information System database, 2011.

RESULTS

Fifty-one percent of the 136,239 observation-status stays in 2011 occurred in 14 hospitals with a dedicated OU; the remainder were in 17 hospitals without. The percentage of observation-status same-day discharges was higher in hospitals with a dedicated OU compared with hospitals without (23.8 vs 22.1, P < 0.001), but risk-adjusted LOS in hours and total standardized costs were similar. Conversion to inpatient status was higher in hospitals with a dedicated OU (11.06%) compared with hospitals without (9.63%, P < 0.01). Adjusted odds of return visits and readmissions were comparable.

CONCLUSIONS

The presence of a dedicated OU appears to have an influence on same-day and morning discharges across all observation-status stays without impacting other hospital-level outcomes. Inclusion of location of care (eg, dedicated OU, inpatient unit, emergency department) in hospital administrative datasets would allow for more meaningful comparisons of models of hospital care.

Failure of Emergency Department Observation Unit Treatment for Skin and Soft Tissue Infections

BACKGROUND

The effectiveness of observation unit (OU) management of skin and soft tissue infections (SSTI) has not been fully evaluated.

OBJECTIVE

This study was performed to determine the rate and risk factors.

METHODS

Retrospective cohort study of children ages 2 months to 18 years admitted to the OU for an SSTI between 2007 and 2010 from a pediatric emergency department (ED). Failure of OU therapy was defined as subsequent inpatient ward admission, re-admission after discharge from OU, initial or repeat incision and drainage after OU admission, or change in antibiotic therapy. Demographic, clinical, and lesion characteristics were collected. Comparative analyses were conducted to determine factors associated with OU failure; prolonged OU admission, defined as length of stay ≥ 36 h was evaluated.

RESULTS

One hundred ninety-two (63.2%) of 304 subjects with SSTI were eligible; mean age was 6.2 ± 5.3 years, and 52% were male. Fever (≥38°C) in the ED was present for 77 (40%). Most lesions were skin abscesses (53%) and were located on the lower extremity (36%) and buttock/genitourinary (21%). OU treatment failure occurred in 22% (95% confidence interval [CI] 16.5-28.3), primarily due to inpatient admission. Fever on ED presentation was significantly associated with OU failure (odds ratio 2.02; 95% CI 1.02-4.02). Demographics, body site, presence of abscess, and methicillin-resistant Staphylococcus aureus were not associated with OU failure. Prolonged OU admission occurred in 18 subjects (9.4%).

CONCLUSION

SSTI can be successfully treated in the OU, though febrile children with SSTI are at risk for OU treatment failure and should be considered for inpatient admission.

A systematic review of predictive modeling for bronchiolitis

PURPOSE

Bronchiolitis is the most common cause of illness leading to hospitalization in young children. At present, many bronchiolitis management decisions are made subjectively, leading to significant practice variation among hospitals and physicians caring for children with bronchiolitis. To standardize care for bronchiolitis, researchers have proposed various models to predict the disease course to help determine a proper management plan. This paper reviews the existing state of the art of predictive modeling for bronchiolitis. Predictive modeling for respiratory syncytial virus (RSV) infection is covered whenever appropriate, as RSV accounts for about 70% of bronchiolitis cases.

METHODS

A systematic review was conducted through a PubMed search up to April 25, 2014. The literature on predictive modeling for bronchiolitis was retrieved using a comprehensive search query, which was developed through an iterative process. Search results were limited to human subjects, the English language, and children (birth to 18 years).

RESULTS

The literature search returned 2312 references in total. After manual review, 168 of these references were determined to be relevant and are discussed in this paper. We identify several limitations and open problems in predictive modeling for bronchiolitis, and provide some preliminary thoughts on how to address them, with the hope to stimulate future research in this domain.

CONCLUSIONS

Many problems remain open in predictive modeling for bronchiolitis. Future studies will need to address them to achieve optimal predictive models.

Treatment of skin and soft tissue infections in a pediatric observation unit

OBJECTIVES

To report the success rate of observation unit (OU) treatment of pediatric skin and soft tissue infections (SSTIs) and to see if we could identify variables at the time of initial evaluation that predicted successful OU treatment.

METHODS

A retrospective review of children less than 18 years of age admitted for SSTI treatment to our OU from the emergency department between January 2003 and June 2009.

RESULTS

On records review, 853 patients matched eligibility criteria; median age was 5.2 years (interquartile range = 2.5-9 years). Of the 853 patients, 597 (70.0%) met the primary outcome criteria of successful OU discharge within 26 hours. Secondary analysis revealed that 82% of the patients achieved successful discharge from the OU within 48 hours. Although some laboratory variables demonstrated statistical association with success, none achieved a combination of high sensitivity and specificity to predict OU failure. OU success rates varied by location. Dental and face infections and those of the extremities or multiple sites demonstrated OU success rates higher than 65%, while infection of the groin, buttocks, trunk, or neck had success rates between 24% (neck) and 60% (groin). In multivariate analysis, only 3 variables remained significant. Unfavorable location was most strongly associated with OU failure, followed by C-reactive protein > 4 and then by erythrocyte sedimentation rate > 20.

CONCLUSIONS

Our findings suggest that successful OU treatment is possible in a large group of patients needing hospitalization for SSTIs. Consideration of infection location may assist the emergency department clinician in determining the most appropriate unit for admission.

Resource utilization for observation-status stays at children's hospitals

BACKGROUND AND OBJECTIVE

Observation status, in contrast to inpatient status, is a billing designation for hospital payment. Observation-status stays are presumed to be shorter and less resource-intensive, but utilization for pediatric observation-status stays has not been studied. The goal of this study was to describe resource utilization characteristics for patients in observation and inpatient status in a national cohort of hospitalized children in the Pediatric Health Information System.

METHODS

This study was a retrospective cohort from 2010 of observation- and inpatient-status stays of ≤2 days; all children were admitted from the emergency department. Costs were analyzed and described. Comparison between costs adjusting for age, severity, and length of stay were conducted by using random-effect mixed models to account for clustering of patients within hospitals.

RESULTS

Observation status was assigned to 67 230 (33.3%) discharges, but its use varied across hospitals (2%-45%). Observation-status stays had total median costs of $2559, including room costs and $678 excluding room costs. Twenty-five diagnoses accounted for 74% of stays in observation status, 4 of which were used for detailed analyses: asthma (n = 6352), viral gastroenteritis (n = 4043), bronchiolitis (n = 3537), and seizure (n = 3289). On average, after risk adjustment, observation-status stays cost $260 less than inpatient-status stays for these select 4 diagnoses. Large overlaps in costs were demonstrated for both types of stay.

CONCLUSIONS

Variability in use of observation status with large overlap in costs and potential lower reimbursement compared with inpatient status calls into question the utility of segmenting patients according to billing status and highlights a financial risk for institutions with a high volume of pediatric patients in observation status.

Unexpected hospitalisations at a 23-hour observation unit in a paediatric emergency department of northern India

BACKGROUND

The 23-hour Observation Unit (OU) is a novel and an effective means for tackling overcrowding in busy Paediatric Emergency Departments (PED) worldwide. However, unexpected hospitalisations in the OU involve transfer of care and they reduce the efficiency of the OU. Hence, we aimed to study the presenting diagnoses which were responsible for the unexpected hospitalisations in a 23-hour OU.

METHODS AND DESIGN

A prospective cohort study Setting: The PED at a tertiary care teaching hospital.

DURATION

15th Feb-15th March 2011.

PROTOCOL

Consecutive children were triaged at presentation to the PED, according to the WHO paediatric emergency triage algorithm. Those who were transferred to the 23-hour OU, were further followed up for duration of the stay, the hospital course, and the outcome (discharge/hospitalisation).

RESULTS

Three hundred (228 males, 72 females) consecutive children who attended the PED over one month were enrolled. All the children, at presentation, were triaged by the medical intern/s who was/were posted in the PED, and they were crosschecked by a PED consultant. A majority (55%, n=165) of the children were triaged as non-urgent, 32% (n=97) as priority and 13% (n=38) as emergent. Out of the 300 children, 173(58%) were transferred to the 23-hour OU. Of these, 16 (9.1%) required unexpected hospitalisations. The children who required hospitalisations had the following diagnoses: bronchiolitis (4), bronchopneumonia (4), seizure (2), viral hepatitis (2), high fever (1), bronchial asthma (1), severe anaemia (1), and urticaria (1). The mean duration of the stay in the OU was 19 hours for those who needed hospitalisation, as against 13 hours for those who were discharged from the OU.

CONCLUSION

The children with respiratory complaints (bronchiolitis and bronchopneumonia) need frequent monitoring in the 23-hour OU, as they have high hospitalisation rates in the OU.

Factors associated with prolonged stay in a pediatric emergency observation unit of an urban tertiary children's hospital in China

OBJECTIVES

This study aimed to examine the factors associated with increased length of stay (LOS > 24 hours) in the pediatric emergency observation unit (OU) of an urban tertiary children's hospital in China.

METHODS

This study was a retrospective cohort study. We retrieved and examined all the records of patients (age, 0-16 years) who were admitted to the OU (n = 10,852) during July 1, 2008, to June 30, 2009. The primary outcome was LOS and prolonged stay (LOS > 24 hours). We also performed a sensitivity analysis by using LOS of 3 days or greater and LOS of 6 days or greater as dependent variables in logistic regression and compared with LOS of greater than 24 hours regression to examine the robustness of the associations.

RESULTS

The overall mean (SD) LOS was 24.0 (24.4) hours; 31.3% had LOS of greater than 24 hours, of which the mean (SD) LOS was 50.2 (28.6) hours. The following factors were associated with LOS of greater than 24 hours: age, 28 days to 3 months (odds ratio, [OR], 1.87; 95% confidence interval, 1.36-2.59) and older than 3 months to 12 months (OR, 1.83; 95% CI, 1.35-2.50) compared with age 0 to 28 days; neurologic diseases (OR, 1.50; 95% CI, 1.31-1.72), infectious diseases (OR, 2.00; 95% CI, 1.61-2.49), and visits for non-respiratory-related signs and symptoms (OR, 2.00; 95% CI, 1.61-2.49); acuity level of emergent (OR, 1.79; 95% CI, 1.57-2.04); procedures (OR, 7.09; 95% CI, 4.16-12.10); emergency transfusions (OR, 1.33; 95% CI, 1.01-1.75); staffed by residents (OR, 1.12; 95% CI, 1.01-1.24); and patients living in low-annual gross domestic product districts (OR, 1.14; 95% CI, 1.01-1.29). Arrival at evening (OR, 0.54; 95% CI, 0.49-0.60) and overnight (OR, 0.43; 95% CI, 0.38-0.49) were less likely to have LOS of greater than 24 hours than arrival during day shifts.

CONCLUSIONS

We identified some risk factors for prolonged stay in an OU. These factors are the starting points in understanding issues related to prolonged stay and are needed to assess efficiency and quality of care in pediatric emergency department and OU. Our results have provided information basis for making improvements in the system and may be important considerations for similar institutions, which encounter similar challenges.

Risk factors for admission in children with bronchiolitis from pediatric emergency department observation unit

BACKGROUND

Patients with bronchiolitis are increasingly being admitted to emergency department observation units (EDOUs) but often require subsequent hospitalization. To better identify ED patients who should be directly admitted to the hospital rather than the EDOU, the predictors of admission must be identified.

OBJECTIVES

The objective of this study was to determine the predictors of subsequent hospital admission from the EDOU in infants and young children with bronchiolitis.

METHOD

This was a retrospective cohort study of patients younger than 2 years admitted to an EDOU with bronchiolitis between April 1, 2003, and March 31, 2007. Univariate analysis was followed by logistic regression to identify the significant predictors of hospital admission from the EDOU.

RESULTS

There were 325 patients in the study: 67% were younger than 6 months, and 60% were male. Eighty-five (26%) were admitted to the hospital from the EDOU. Predictors for admission from the EDOU included parental report of poor feeding or increased work of breathing, oxygen saturation less than 93%, or ED treatment with racemic epinephrine (Vaponephrine) and intravenous fluids (IVFs).

CONCLUSION

Patients with a history of increased work of breathing or oxygen saturation less than 93% and ED treatment with IVFs are at high risk for admission from the EDOU to the hospital. Direct admission to the hospital from the ED should be considered for these patients, particularly patients treated with IVFs and having an oxygen saturation less than 93% in the ED.

Utilization of a pediatric observation unit for toxicologic ingestions

OBJECTIVES

The objectives of this study were to evaluate the efficacy and utilization of an observation unit (OU) for admission of pediatric patients after a toxicologic ingestion; compare the characteristics and outcomes of patients admitted to the pediatric OU, inpatient (IP) service, and intensive care unit (ICU) after ingestions using retrospective chart review; and attempt to identify factors associated with unplanned IP admission after an OU admission.

METHODS

This was a retrospective chart review of children seen in the emergency department (ED) after potentially toxic suspected ingestions and then admitted to the OU, IP service, or ICU from June 2003 to September 2007.

RESULTS

One thousand twenty-three children were seen in the ED for ingestions: 18% were admitted to the OU, 15% to the IP service service, and 6% to the ICU. Observation unit patients had less mental status changes reported and were less frequently given medications while in the ED. Eighty-one percent of OU patients were admitted with poison center recommendation. Ninety-four percent of OU patients were discharged within 24 hours, and less than half of IP service/ICU patients were discharged that quickly. No significant associations were found between specific historical and physical examination or laboratory characteristics in the ED and the need for unplanned IP admission.

CONCLUSIONS

Observation unit patients admitted after ingestions were young, typically ingested substances found in the home, and required observation according to poison center recommendations. Ninety-four percent were able to be discharged home within 24 hours even after ingesting some of the most concerning substances such as central nervous system depressants, cardiac/antihypertension medications, hypoglycemics, and opiates. All OU patients did well without any adverse events reported. Many patients requiring prolonged observation after an ingestion, and who do not require ICU care, may be appropriate for OU management. This study suggests a potential underutilization of observation units in this setting.

Pediatric observation status: are we overlooking a growing population in children's hospitals?

BACKGROUND

Inpatient administrative datasets often exclude observation stays, as observation is considered to be outpatient care. The extent to which this status is applied to pediatric hospitalizations is not known.

OBJECTIVE

To characterize trends in observation status code utilization and 1-day stays among children admitted from the emergency department (ED), and to compare patient characteristics and outcomes associated with observation versus inpatient stays.

DESIGN

Retrospective longitudinal analysis of the 2004-2009 Pediatric Health Information System (PHIS).

SETTING

Sixteen US freestanding children's hospitals contributing outpatient and inpatient data to PHIS.

PATIENTS

Admissions to observation or inpatient status following ED care in study hospitals.

MEASUREMENTS

Proportions of observation and 1-day stays among all admissions from the ED were calculated each year. Top ranking discharge diagnoses and outcomes of observation were determined. Patient characteristics, discharge diagnoses, and return visits were compared for observation and 1-day stays.

RESULTS

The proportion of short-stays (including both observation and 1-day stays) increased from 37% to 41% between 2004 and 2009. Since 2007, observation stays have outnumbered 1-day stays. In 2009, more than half of admissions from the ED for 6 of the top 10 ranking discharge diagnoses were short-stays. Fewer than 25% of observation stays converted to inpatient status. Return visits and readmissions following observation were no more frequent than following 1-day stays.

CONCLUSIONS

Children admitted under observation status make up a substantial proportion of acute care hospitalizations. Analyses of inpatient administrative databases that exclude observation stays likely result in an underestimation of hospital resource utilization for children.

Emergency department observation units: A clinical and financial benefit for hospitals

INTRODUCTION

There are nearly 120 million visits to emergency departments each year, one for every three people in the United States. Fifty percent of all hospital admissions come from this group, a marked change from the mid-1990s when the emergency department was a source of only a third of admissions. As the population increases and ages, the growth rate for emergency department visits and the resulting admissions will exceed historical trends creating a surge in demand for inpatient beds.

BACKGROUND

Current health care reform efforts are highlighting deficiencies in access, cost, and quality of care in the United States. The need for more inpatient capacity brings attention to short-stay admissions and whether they are necessary. Emergency department observation units provide a suitable alternate venue for many such patients at lower cost without adversely affecting access or quality.

METHODS

This article serves as a literature synthesis in support of observation units, with special emphasis on the clinical and financial aspects of their use. The observation medicine literature was reviewed using PubMed, and selected sources were used to summarize the current state of practice. In addition, the authors introduce a novel conceptual framework around measures of observation unit efficiency.

FINDINGS AND PRACTICE IMPLICATIONS

Observation units provide high-quality and efficient care to patients with common complaints seen in the emergency department. More frequent use of observation can increase patient safety and satisfaction while decreasing unnecessary inpatient admissions and improving fiscal performance for both emergency departments and the hospitals in which they operate. For institutions with the volume to justify the fixed costs of operating an observation unit, the dominant strategy for all stakeholders is to create one.

Pediatric observation units

Pediatric observation units (OUs) are hospital areas used to provide medical evaluation and/or management for health-related conditions in children, typically for a well-defined, brief period. Pediatric OUs represent an emerging alternative site of care for selected groups of children who historically may have received their treatment in an ambulatory setting, emergency department, or hospital-based inpatient unit. This clinical report provides an overview of pediatric OUs, including the definitions and operating characteristics of different types of OUs, quality considerations and coding for observation services, and the effect of OUs on inpatient hospital utilization.

Differences in designations of observation care in US freestanding children's hospitals: are they virtual or real?

OBJECTIVE

To characterize practices related to observation care and to examine the current models of pediatric observation medicine in US children's hospitals.

DESIGN

We utilized 2 web-based surveys to examine observation care in the 42 hospitals participating in the Pediatric Health Information System database. We obtained information regarding the designation of observation status, including the criteria used to admit patients into observation. From hospitals reporting the use of observation status, we requested specific details relating to the structures of observation care and the processes of care for observation patients following emergency department treatment.

RESULTS

A total of 37 hospitals responded to Survey 1, and 20 hospitals responded to Survey 2. Designated observation units were present in only 12 of 31 (39%) hospitals that report observation patient data to the Pediatric Health Information System. Observation status was variably defined in terms of duration of treatment and prespecified criteria. Observation periods were limited to <48 hours in 24 of 31 (77%) hospitals. Hospitals reported that various standards were used by different payers to determine observation status reimbursement. Observation care was delivered in a variety of settings. Most hospitals indicated that there were no differences in the clinical care delivered to virtual observation status patients when compared with other inpatients.

CONCLUSIONS

Observation is a variably applied patient status, defined differently by individual hospitals. Consistency in the designation of patients under observation status among hospitals and payers may be necessary to compare quality outcomes and costs, as well as optimize models of pediatric observation care.

Effectiveness of multifunction paediatric short-stay units: a French multicentre study

AIM

To describe the characteristics of the activities of multifunction paediatric 'short-stay units' (SSU) including observation unit (OU), medical assessment and planning unit (MAPU) and holding unit (HU), to evaluate their effectiveness and to explore predictors of inappropriate admissions for OU patients.

METHODS

Admissions to nine French paediatric SSUs were analysed. The main outcome measures were SSU length of stay with associated outcome for all patients and appropriate admission rate for OU patients.

RESULTS

Of 1084 patients included in the study, 66% were OU patients (n = 718), 21% MAPU patients (n = 225) and 13% HU patients (n = 141). The OU patients constituted the majority of the SSU admissions. The appropriate OU admission rates ranged from 52% to 86%. Head trauma and seizure were the conditions with the highest appropriate OU admission rates (82%). Age <1 year, and need for IV fluids or medications, CT-Scan or MRI and cardiorespiratory monitoring were associated with an increased risk of inappropriate OU admission. Eighteen per cent of the MAPU patients and 5% of the HU patients were discharged home within 24 h.

CONCLUSION

By providing extended and easily available facilities for diagnostics and early treatment for a wide range of sick children, the French paediatric SSU is an effective model for 'observation medicine' in emergency department-managed units. The experience and principles may be applicable to similar units in other health care systems.

Barriers to discharge from a 24-hour observation unit for children with bronchiolitis

OBJECTIVES

The aim of this study was to determine physician-identified barriers to discharge of patients with bronchiolitis from a 24-hour emergency department-based observation unit.

METHODS

Patients 3 to 24 months of age with a diagnosis of bronchiolitis were prospectively enrolled from January through April 2008. Patients were treated according to a standard hospital-wide bronchiolitis pathway that included an option for discharge on home oxygen. Treating physicians recorded barriers to discharge in those not sent home within 24 hours. The primary outcome was successful discharge within 24 hours; we analyzed barriers to such discharges.

RESULTS

Fifty-five patients were enrolled in the study. Discharge within 24 hours failed in 30 patients (55%; 95% confidence interval [CI], 42%-67%). Among the 25 discharged patients, 6 (24%) went home on supplemental oxygen without adverse outcomes or readmission. Hypoxia was the most commonly identified barrier to discharge (n = 22, 73%). Of the 22 cases where hypoxia was a barrier, 18 (82%) also noted the need for deep nasal suctioning; 12 (55%), parental discomfort; 12 (55%), respiratory distress; 10 (46%), poor feeding; and 4 (18%), MD discomfort.

CONCLUSIONS

Hypoxia was the most common barrier to discharge within 24 hours for patients with bronchiolitis, and a common cofactor when other barriers were identified. Research on home oxygen, the use of deep nasal suctioning, and parental discomfort with early discharge may be useful in reducing the need for inpatient care for bronchiolitis.

High turnover stays for pediatric asthma in the United States: analysis of the 2006 Kids' Inpatient Database

BACKGROUND

Pediatric observation units provide an alternative to traditional hospitalization. The extent to which observation units could replace inpatient care for asthmatic children is unknown.

OBJECTIVE

To describe brief inpatient ("high-turnover," HTO) stays for US children hospitalized with a principal discharge diagnosis of asthma, to characterize cases that may be appropriate for observation.

DESIGN

We analyzed the 2006 Kids' Inpatient Database, a nationally representative sample of hospital discharges. HTO stays were defined as hospitalizations of 0 or 1 night in duration. We conducted descriptive statistics and case-mix adjusted, sample-weighted regression analysis of HTO stays, and associated hospital charges.

SUBJECTS

Discharges among children aged 2 to 20 years with a principal discharge diagnosis of asthma.

MEASURES

HTO stays and total charges.

RESULTS

Overall, 34,592 (34%) pediatric asthma hospitalizations were HTO, accounting for 66,278 hospital days in 2006. HTO stays were associated with younger age, uncomplicated asthma, and private insurance. Freestanding children's hospitals had the highest proportion of HTO stays, 38% (95% CI: 34%-42%) compared with 32% (95% CI: 28%-36%) for children's units and 33% (95% CI: 31%-34%) for general hospitals. In multivariate regression analyses, charges were significantly higher across hospital types when HTO stays begin in the emergency department.

CONCLUSIONS

The presence of a large number of HTO stays for children hospitalized for asthma suggests the need to explore opportunities to restructure care for this condition, perhaps through the development of physically or operationally distinct observation units.

Pediatric observation units in the United States: a systematic review

BACKGROUND

As more efficient and value-based care models are sought for the US healthcare system, geographically distinct observation units (OUs) may become an integral part of hospital-based care for children.

PURPOSE

To systematically review the literature and evaluate the structure and function of pediatric OUs in the United States.

DATA SOURCES

Searches were conducted in Medline, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Health Care Advisory Board (HCAB), Lexis-Nexis, National Guideline Clearinghouse, and Cochrane Reviews, through February 2009, with review of select bibliographies.

STUDY SELECTION

English language peer-reviewed publications on pediatric OU care in the United States.

DATA EXTRACTION

Two authors independently determined study eligibility. Studies were graded using a 5-level quality assessment tool. Data were extracted using a standardized form.

DATA SYNTHESIS

A total of 21 studies met inclusion criteria: 2 randomized trials, 2 prospective observational, 12 retrospective cohort, 2 before and after, and 3 descriptive studies. Studies present data on more than 22,000 children cared for in OUs, most at large academic centers. This systematic review provides a descriptive overview of the structure and function of pediatric OUs in the United States. Despite seemingly straightforward outcomes for OU care, significant heterogeneity in the reporting of length of stay, admission rates, return visit rates, and costs precluded our ability to conduct meta-analyses. We propose standard outcome measures and future directions for pediatric OU research.

CONCLUSIONS

Future research using consistent outcome measures will be critical to determining whether OUs can improve the quality and cost of providing care to children requiring observation-length stays.

Observation unit experience for pediatric poison exposures

BACKGROUND

Short-Stay Emergency Department Observation Units (OU) are an alternative to hospitalization, but data on OU care of pediatric poisoning exposures is limited. We report the experience of a pediatric OU with this population.

METHODS

We retrospectively reviewed the charts of children with poison exposure admitted to a pediatric OU during a 30-month period. Data was collected pertaining to demographics, type of exposure, clinical presentation, and rate of hospitalization, and was compared to nonpoisoned OU patients.

RESULTS

Of the 91 pediatric patients with poison exposure, 86 complete charts were available for review (94.5%). Of these patients, 49.5% were female, and 82.4% were <6 years of age (range 1.5 months to 16.6 years). There were a total of 98 toxicants implicated, the most common of which were psychoactive drugs (25%) and cardiovascular agents (19%). At OU admission, 33 of 88 patients (38%) had altered mental status or abnormal vital signs. Only 2 of the 53 remaining patients developed abnormal vital signs within the OU. Two patients were hospitalized unexpectedly with respiratory distress due to hydrocarbon and charcoal aspiration pneumonitis, respectively; the unexpected hospitalization rate was 2.2%. Three more planned hospitalizations for endoscopy or psychiatric evaluation led to a total hospitalization rate of 5.4%. This hospitalization rate is significantly lower (RR=0.26, 95% CI=0.11-0.62) than the hospitalization rate from the OU for nonpoisoned patients (20.3%) during that time. Mean OU length of stay for nonadmitted poisoned patients was 14.35 hours. There were no adverse events noted as a result of OU placement.

CONCLUSION

Select poisoned pediatric patients appear suitable for OU management and had less frequent unexpected hospitalization from the OU than other diagnoses.
