Unseen patterns of preventable emergency care: Emergency department visits for ambulatory care sensitive conditions.
Ontology highlight
ABSTRACT: Objective
Admissions for ambulatory care sensitive conditions (ACSCs) are often used to measure potentially preventable emergency care. Visits to emergency departments with ACSCs may also be preventable care but are excluded from such measures if patients are not admitted. We established the extent and composition of this preventable emergency care.Methods
We analysed 1,505,979 emergency department visits (5% of the national total) between 1 April 2015 and 31 March 2017 at six hospital Trusts in England, using International Classification of Diseases diagnostic coding. We calculated the number of visits for each ACSC and examined the proportions of these visits that did not result in admission by condition and patient characteristics.Results
11.1% of emergency department visits were for ACSCs. 55.0% of these visits did not result in hospital admission. Whilst the majority of ACSC visits were for acute rather than chronic conditions (59.4% versus 38.4%), acute visits were much more likely to conclude without admission (70.3% versus 33.4%). Younger, more deprived and ethnic minority patients were less likely to be admitted when they visited the emergency department with an ACSC.Conclusions
Over half of preventable emergency care is not captured by measures of admissions. The probability of admission at a preventable visit varies substantially between conditions and patient groups. Focussing only on admissions for ACSCs provides an incomplete and skewed picture of the types of conditions and patients receiving preventable care. Measures of preventable emergency care should include visits in addition to admissions.

Project description:Many countries worldwide are aging rapidly, and the complex care needs of older adults generate an unprecedented demand for health services. Common reasons for elderly emergency department (ED) visits frequently involve conditions triggered by preventable infections also known as ambulatory care sensitive conditions (ACSCs). This study aims to describe the trend and the associated disease burden attributable to ACSC-related ED visits made by elderly patients and to characterize their ED use by nursing home residence. We designed a population-based ecological study using administrative data on Taiwan EDs between 2002 and 2013. A total of 563,647 ED visits from individuals aged 65 or over were examined. All elderly ED visits due to ACSCs (tuberculosis, upper respiratory infection, pneumonia, sepsis, cellulitis and urinary tract infection (UTI)) were further identified. Subsequent hospital admissions, related deaths after discharge, total health care costs and disability-adjusted life years (DALYs) were compared among different ACSCs. Prevalence of ACSCs was then assessed between nursing home (NH) residents and non-NH residents. Within the 12-year observation period, we find that there was a steady increase in both the rate of ACSC ED visits and the proportion of elderly with a visit. Overall, pneumonia is the most prevalent among six ACSCs for elderly ED visits (2.10%; 2.06 to 2.14), subsequent hospital admissions (5.77%; 5.59 to 5.94) and associated mortality following admission (17.37%; 16.74 to 18.01). UTI is the second prevalent ACSC consistently across ED visits (2.02%; 1.98 to 2.05), subsequent hospital admissions (2.36%, 2.25 to 2.48) and mortality following admission (10.80%; 10.28 to 11.32). Sepsis ranks third highest in the proportion of hospitalization following ED visit (2.29%; 2.18 to 2.41) and related deaths after hospital discharge (7.39%; 6.95 to 7.83), but it accounts for the highest average total health care expenditure (NT$94,595 ± 120,239; ≈US$3185.02) per case. When examining the likelihood of ACSC-attributable ED use, significantly higher odds were observed in NH residents as compared with non-NH residents for: pneumonia (adjusted odds ratio (aOR): 5.01, 95% confidence interval (CI) 4.50-5.58); UTI (aOR: 4.44, 95% CI 3.97-4.98); sepsis (aOR: 3.54, 95% CI 3.06-4.10); and tuberculosis (aOR: 2.44, 95% CI 1.63-3.65). Here we examined the ACSC-related ED care and found that, among the six ACSCs studied, pneumonia, UTI and sepsis were the leading causes of ED visits, subsequent hospital admissions, related mortality, health care costs and DALYs in Taiwanese NH elderly adults. Our findings suggest that efficient monitoring and reinforcing of quality of care in the residential and community setting might substantially reduce the number of preventable elderly ED visits and alleviate strain on the health care system.

Project description:ObjectiveTo investigate the types of parental psychiatric and pain-related (PR) conditions that are associated with inadequate management of children's health and medical needs.Data sourcesThe 1997-1998 Thomson/Medstat MarketScan claims and administrative dataset.Study designA cross-sectional study that assessed the associations between parents' claims for psychiatric and PR conditions, and their children's well-child care as well as emergency department (ED) visits and hospitalizations for conditions that can be treated effectively in outpatient settings (ambulatory care sensitive [ACS] conditions).Data extraction methodsClaims were extracted for 258,313 children of ages 0-17 years and their parents, who had insurance coverage for a full 2-year period.Principle findingsMultiple parental psychiatric and PR diagnoses were associated with child ACS emergency services/hospitalizations. Maternal depression was negatively associated with a child having the recommended well-child visits (odds ratio [OR]: 0.92, 95 percent confidence intervals [CI]: 0.84-0.99). The combined diagnoses of maternal depression and back pain was positively associated with a child having an ACS-ED visit (OR: 1.64, 95 percent CI: 1.33-2.03) and a child having an ACS hospitalization (OR: 2.04, 95 percent CI: 1.34-3.09).ConclusionsPediatricians' ability to manage child health may be enhanced with coordinated management of parental psychopathology and PR health conditions.

Project description:Background/objectivesThis study examined urban/rural differences in the frequency of preventable emergency department (ED) visits among patients with Alzheimer's disease and related dementias (ADRD), with a focus on the variation of accountable care organization (ACO) participation status for hospitals in urban and rural areas.DesignWe performed a cross-sectional study using the 2015 State Emergency Department Databases, the American Hospital Association Annual Survey of Hospitals, and the Area Health Resource File. Individual-, county-, and hospital-level characteristics and state fixed effects were used for model specification.SettingPatients with ADRD from seven states who visited the ED and had routine discharges.ParticipantsOur sample consisted of 117,196 patients with ADRD.MeasurementsThe outcome was preventable ED visits classified using the New York University Emergency Department visit algorithm. We performed a multivariable logistic regression to estimate the variation of preventable ED visits by urban and rural areas.ResultsRural patients with ADRD had 1.13 higher adjusted odds (P = .007) of going to the ED for a preventable visit compared with their urban counterparts. In addition, ACO-affiliated hospitals had .91 lower adjusted odds (P = .005) of preventable ED visits for ADRD patients compared with hospitals not affiliated with an ACO. Whole-county Mental Health Care Health Professional Shortage Area (HPSA) (odds ratio = 1.14; P = .002) designation was also an indicator of higher preventable ED rates.ConclusionACO delivery systems have the potential to decrease rural preventable ED visits among ADRD patients.

Project description:ObjectivesIn the United States the percentage of Medicaid enrollees in some form of Medicaid managed care has increased more than seven-fold since 1990, e.g., up from 11% in 1991 to 82% in 2017. Yet little is known about whether and how this major change in Medicaid insurance affects how recipients use hospital emergency rooms. This study compares the performance of Medicaid health maintenance organizations (HMOs) and fee-for-service (FFS) Medicaid regarding the occurrence of potentially preventable emergency department (ED) use.MethodsUsing data from the 2003-2015 Medical Expenditure Panel Survey (MEPS), a nationally representative survey of the non-institutionalized US population, we estimated multivariable logistic regression models to examine the relationship between Medicaid HMO status and potentially preventable ED use. To accommodate the composition of the Medicaid population, we conducted separate repeated cross-sectional analyses for recipients insured through both Medicaid and Medicare (dual eligibles) and for those insured through Medicaid only (non-duals). We explicitly addressed the possibility of selection bias into HMOs in our models using propensity score weighting.ResultsWe found that the type of Medicaid held by a recipient, i.e., whether an HMO or FFS coverage, was unrelated to the probability that an ED visit was potentially preventable. This finding emerged both among dual eligibles and among non-duals, and it occurred irrespective of the adopted analytical strategy.ConclusionsWithin the U.S. Medicaid program, Medicaid HMO and FFS enrollees are indistinguishable in terms of the occurrence of potentially preventable ED use. Policymakers should consider this finding when evaluating the pros and cons of adopting Medicaid managed care.

Project description:OBJECTIVES:Reducing nursing home hospitalizations for ambulatory care sensitive conditions (ACSC) has been identified as an opportunity to improve patient well-being and reduce costs. The aim of this study was to identify number of hospitalizations for ACSCs for nursing home residents in a Swiss national sample, examine demographic characteristics of nursing home hospitalizations due to ACSCs, and calculate hospital expenses from these hospitalizations. METHODS:Using merged hospital administrative data with payment data based on diagnosis-related groups (DRGs) for the year 2013, we descriptively examined nursing home residents who were 65 years of age or older and were admitted to an acute care hospital. RESULTS:Approximately 42% of all nursing home admissions were due to ACSCs. Payments to Swiss hospitals for ACSCs can be estimated at between 89 and 105 million Swiss francs in 2013. CONCLUSIONS:A sizable share of hospitalizations for nursing home residents is for ACSCs, and the associated costs are substantial. Programs and policies designed to reduce these potentially avoidable hospitalizations from the nursing home setting could lead to an increased patient well-being and lower costs.

Project description:BackgroundIn an effort to address health care spending growth, coordinate care, and improve access to primary care in the Medicaid program, Florida implemented the Statewide Mandatory Managed Care (SMMC) program in May of 2014.ObjectivesThe objective of this study is to investigate the impact of implementation of mandatory managed care in Medicaid on the preventable emergency department (ED) utilizations, with a focus on racial/ethnic minorities.Research designThe primary data source is the universe of Florida ED visit and inpatient discharge data from 2010 to 2015, maintained by the Florida Agency for Health Care Administration. We adopt the New York University Billing's ED Classification Algorithm to create measures for preventable ED visits. Using difference-in-differences estimation, we examine preventable ED visits for Florida residents aged 18-64 with a primary payer of Medicaid (treatment group) and private health insurance (control group) pre-SMMC and post-SMMC reform.ResultsOur findings show that SMMC is statistically significantly associated with more reductions in preventable ED visits among non-Hispanic African American (incidence rate ratio=0.81; 95% confidence interval, 0.70-0.94) and Hispanic (incidence rate ratio=0.72; 95% CI, 0.60-0.87) Medicaid enrollees relative to their white counterparts. We also find significant reduction of racial/ethnic disparities only in counties with above median preimplementation Medicaid managed care penetration rate.ConclusionsOur findings suggest that implementation of Medicaid mandatory managed care in Florida is associated with reduced racial/ethnic disparities in preventable ED visits.

Project description:ImportanceMonitoring emergency care quality requires understanding which conditions benefit most from timely, quality emergency care.ObjectivesTo identify a set of emergency care-sensitive conditions (ECSCs) that are treated in most emergency departments (EDs), are associated with a spectrum of adult age groups, and represent common reasons for seeking emergency care and to provide benchmark national estimates of ECSC acute care utilization.Design, setting, and participantsA modified Delphi method was used to identify ECSCs. In a cross-sectional analysis, ECSC-associated visits by adults (aged ≥18 years) were identified based on International Statistical Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes and analyzed with nationally representative data from the 2016 US Nationwide Emergency Department Sample. Data analysis was conducted from January 2018 to December 2018.Main outcomes and measuresIdentification of ECSCs and ECSC-associated ED utilization patterns, length of stay, and charges.ResultsAn expert panel rated 51 condition groups as emergency care sensitive. Emergency care-sensitive conditions represented 16 033 359 of 114 323 044 ED visits (14.0%) in 2016. On average, 8 535 261 of 17 886 220 ED admissions (47.7%) were attributed to ECSCs. The most common ECSC ED visits were for sepsis (1 716 004 [10.7%]), chronic obstructive pulmonary disease (1 273 319 [7.9%]), pneumonia (1 263 971 [7.9%]), asthma (970 829 [6.1%]), and heart failure (911 602 [5.7%]) but varied by age group. Median (interquartile range) length of stay for ECSC ED admissions was longer than non-ECSC ED admissions (3.2 [1.7-5.8] days vs 2.7 [1.4-4.9] days; P < .001). In 2016, median (interquartile range) ED charges per visit for ECSCs were $2736 ($1684-$4605) compared with $2179 ($1118-$4359) per visit for non-ECSC ED visits (P < .001).Conclusions and relevanceThis comprehensive list of ECSCs can be used to guide indicator development for pre-ED, intra-ED, and post-ED care and overall assessment of the adult, non-mental health, acute care system. Health care utilization and costs among patients with ECSCs are substantial and warrant future study of validation, variations in care, and outcomes associated with ECSCs.

Project description:ObjectivesTo examine the spatial and temporal patterns of English general practices' emergency admissions for Ambulatory Care Sensitive Conditions (ACSCs).DesignObservational study of practice level annual hospital emergency admissions data for ACSCs for all English practices from 2004-2017.ParticipantsAll patients with an emergency admission to a National Health Service hospital in England who were registered with an English general practice.Main outcome measurePractice level age and gender indirectly standardised ratios (ISARs) for emergency admissions for ACSC.ResultsIn 2017, 41.8% of the total variation in ISARs across practices was between the 207 Clinical Commissioning Groups (CCGs) (the administrative unit for general practices) and 58.2% was across practices within CCGs. ACSC ISARs increased by 4.7% between 2004 and 2017, while those for conditions incentivised by the Quality and Outcomes Framework (QOF) fell by 20%. Practice ISARs are persistent: practices with high rates in 2004 also had high rates in 2017. Standardising by deprivation as well as age and gender reduced the coefficient of variation of practice ISARs in 2017 by 22%.ConclusionsThere is persistent spatial pattern of emergency admissions for ACSC across England both within and across CCGs. We illustrate the reduction in ACSCs emergency admissions across the study period for conditions incentivised by the QOF but find that this was not accompanied by a reduction in variation in these admissions across practices. The observed spatial pattern persists when admission rates are standardised by deprivation. The persistence of spatial clusters of high emergency admissions for ACSCs within and across CCG boundaries suggests that policies to reduce potentially unwarranted variation should be targeted at practice level.

Project description:Background and importanceThe differentiation between patients who require urgent care and those who could receive adequate care through ambulatory services remains a challenge in managing patient volumes in emergency departments (ED). Different approaches were pursued to characterize patients that could safely divert to ambulatory care. However, this characterization remains challenging as the urgency upon presentation is assessed based on immediately available characteristics of the patients rather than on subsequent diagnoses. This work employs a core set of Ambulatory Care Sensitive Conditions (core-ACSCs) in an ED to describe conditions that do not require inpatient care if treated adequately in the ambulatory care sector. It subsequently analyzes the corresponding triage levels and admission status to determine whether core-ACSCs relevantly contribute to patient volumes in an ED.Settings and participantsSingle center cross-sectional analysis of routine data of a tertiary ED in 2019.Outcome measures and analysisThe proportion of core-ACSCs among all presentations was assessed. Triage levels were binarily classified as "urgent" and "non-urgent," and the distribution of core-ACSCs in both categories was studied. Additionally, the patients presenting with core-ACSCs requiring inpatient care were assessed based on adjusted residuals and logistic regression. The proportion being discharged home underwent further investigation.Main resultsThis study analyzed 43,382 cases of which 10.79% (n = 4,683) fell under the definition of core-ACSC categories. 65.2% of all core-ACSCs were urgent and received inpatient care in 62.8% of the urgent cases. 34.8% of the core-ACSCs were categorized as non-urgent, 92.4% of wich were discharged home. Age, triage level and sex significantly affected the odds of requiring hospital admission after presenting with core-ACSCs. The two core-ACSCs that mainly contributed to non-urgent cases discharged home after the presentation were "back pain" and "soft tissue disorders."DiscussionCore-ACSCs contribute relevantly to overall ED patient volume but cannot be considered the primary drivers of crowding. However, once patients presented to the ED with what was later confirmed as a core-ACSC, they required urgent care in 65.2%. This finding highlights the importance of effective ambulatory care to avoid emergency presentations. Additionally, the core-ACSC categories "back pain" and "soft tissue disorders" were often found to be non-urgent and discharged home. Although further research is required, these core-ACSCs could be considered potentially avoidable ED presentations.Clinical trial registrationThe study was registered in the German trials register (DRKS-ID: DRKS00029751) on 2022-07-22.
