Community paramedicine in Central Oregon: A promising model to reduce non-urgent emergency department utilization among medically complex Medicaid beneficiaries.

Community paramedicine has emerged as a promising model to redirect persons with nonmedically emergent conditions to more appropriate and less expensive community-based health care settings. Outreach through community paramedicine to patients with a history of high hospital emergency department (ED) use and chronic health conditions has been found to reduce ED use. This study examined the effect of community paramedicine implemented in 2 rural counties in reducing nonemergent ED use among a sample of Medicaid beneficiaries with complex medical conditions and a history of high ED utilization. A cluster randomized trial approach with a stepped wedge design was used to test the effect of the community paramedicine intervention. ED utilization for non-urgent care was measured by emergency medicine ED visits and avoidable ED visits. The community paramedicine intervention reduced ED utilization among a sample of 102 medically complex Medicaid beneficiaries with a history of high ED utilization. In the unadjusted models, emergency medical ED visits decreased by 13.9% (incidence rate ratio [IRR], 0.86; 95% confidence interval [CI], 0.76-0.98) or 6.1 visits saved for every 100 people. Avoidable emergency department visits decreased by 38.9% (IRR, 0.61; 95% CI, 0.44-0.84) or 2.3 visits saved for every 100 people. Our results suggest community paramedicine is a promising model to achieve a reduction in ED utilization among medically complex patients by managing complex health conditions in a home-based setting.

Evaluation of a transitions clinic to bridge emergency department and primary care.

Suboptimal transitions from the emergency department (ED) to ambulatory settings contribute to poor clinical outcomes and unnecessary nonurgent ED utilization. Care transition clinics (CTCs) are a potential solution by providing ED follow-up and facilitating the bridge to longer-term primary care. The objective was to evaluate the implementation of an ED transitions clinic on 30-day ED revisits and hospital readmissions. Retrospective cross-sectional study. This study included adults 18 years and older discharged from the ED and reeferred to the CTC. Appointment attendance, follow-up time, and frequencies of care type provided were computed to assess clinic utilization. Rates of 30-day ED revisit and hospital admission were compared between completed and missed appointments using logistic regression. Between March 2021 and March 2022, 373 patients were referred to the CTC totaling 405 appointments. Half (53%) of appointments were completed with a median follow-up time of 4 days (IQR = [2, 7]). The most common care types provided were wound care (44%) and clinical problem management (33%), with wound care appointments more likely to be completed compared with clinical appointments (OR = 1.7, CI = [1.1, 2.8], p = .03). Patients who completed their CTC appointment were 50% less likely to return to the ED in 30 days compared with those who did not complete their appointment (OR = 0.51, CI = [0.27, 0.98], p < .05). No effect was seen for CTC appointment completion on hospital readmission. Transition clinics are a viable method to provide timely access to follow-up for patients discharged from the ED and may help reduce excess ED use for ambulatory care needs.

Avoidable Emergency Department Visits: Differences between Texas and Washington Medicaid Enrollees

Administrative claims data from 2012 are used from Texas and Washington State to understand state differences in the likelihood of non-urgent emergency department utilization prior to the implementation of the Affordable Care Act. Texas is currently the largest state that has opted to not expand Medicaid. Washington State has expanded Medicaid, and it had more generous pre-expansion Medicaid income eligibility criterion compared to Texas. I find that emergency department use for non-urgent reasons was higher in Texas compared to the state of Washington in 2012. Additionally, in Texas, there was a disproportionately high demand for obstetric services that are typically provided in outpatient settings. Non-urgent emergency department demand was associated with disruption in Medicaid coverage in both states. In Texas, especially, Medicaid coverage disruption and rural area residency were associated with higher likelihood of emergency department use for emergent but primary care treatable reasons.

Patient perspectives on emergency department self-referral after bariatric surgery

BackgroundReducing avoidable emergency department (ED) visits is an increasingly important target of quality improvement and cost containment efforts in bariatric surgery. Administrative and clinical registry data provide an incomplete picture of the factors contributing to postoperative ED utilization. Patient-centered interviews can help identify intervention opportunities. ObjectivesWe sought to understand the circumstances surrounding patient self-referral to the ED after elective, primary bariatric surgery. SettingA quality improvement collaborative in Michigan. MethodsA prospective review of clinically abstracted data and patient interviews was completed across 40 hospitals participating in a statewide quality improvement collaborative. Trained nurses collected data on the circumstances surrounding patients’ 30-day postoperative ED visits using a previously validated interview tool. Over a year, 201 of 633 total ED visits met the inclusion criteria, with 78% of those patients being interviewed. ResultsThe most common reported chief complaints were abdominal pain and nausea/vomiting. Patients reported high compliance with provider-driven perioperative measures to reduce ED visits. One third of patients stated urgency as the reason for not contacting their surgeon prior to their visit. A majority of patients believed their ED visit was both necessary and unavoidable. ConclusionsMost patients experienced non-life-threatening symptoms but believed their concerns required immediate medical attention in an ED. Patients did not seek lower acuity alternatives despite the increasing availability of these lower cost options. Urgent care centers are one practical alternative for patients who need expeditious professional evaluation. Focused, patient-centered education and promotion of appropriate lower acuity options may decrease nonurgent ED utilization among postoperative bariatric patients.

Nonurgent and urgent emergency department use during pregnancy: an observational study

Emergency department use is common among pregnant women. Nonurgent emergency department use may represent care that would be better provided by an established obstetric provider in an ambulatory setting. The objective of the study was to identify sociodemographic factors associated with nonurgent emergency department use in pregnancy. This is a cross-sectional study of women recruited during their postpartum hospitalization. Data regarding prenatal care and emergency department visits were collected from medical records; participants completed a survey with questions regarding demographics and emergency department use. Urgency of an emergency department visit was prespecified based on a priori criteria abstracted from medical record review. Women with any nonurgent emergency department use were compared with women without nonurgent emergency department use. Logistic regression was performed to identify factors associated with nonurgent emergency department use. Two hundred thirty-three women participated in this study; 197 (84%) received care in the emergency department during pregnancy. Eighty-three women (35.6%) had at least 1 visit to the emergency department that was nonurgent. In a regression analysis, the increased odds of nonurgent emergency department use was associated with a preferred language other than English (odds ratio, 2.02; 95% confidence interval,1.01-4.05) and lack of private insurance (odds ratio, 5.55; 95% confidence interval, 2.54-12.12). The 2 most common reasons for presentation to the emergency department were concern that there was an emergency (45%) or being referred by a health care provider (36%). Women frequently use the emergency department during pregnancy, including visits for nonurgent indications. Identifying risk factors for nonurgent emergency department use in pregnancy is important for identifying women likely to use the emergency department, including for nonurgent visits, and the development of strategies to decrease nonurgent emergency department utilization in pregnancy.

Demographic factors influencing nonurgent emergency department utilization among a Medicaid population.

To use administrative medical encounter data to examine nonurgent emergency department (ED) utilization as it relates to member characteristics (i.e., age, gender, race/ethnicity, urbanicity and federal poverty level (FPL)). This 1year cross-sectional study used medical claims from a managed care organization for Medicaid members enrolled from October 1, 2010 - September 30, 2011. ED encounters occurring during the study period were classified as either urgent or nonurgent using ICD-9 diagnosis codes obtained from medical claims. Examples of urgent diagnoses include head traumas, burns, allergic reactions, poisonings, preterm labor or maternal/fetal distress. A total of 187,263 members aged 2 to 65years were retained for study. A zero-inflated Poisson regression model examined the influence of member-level characteristics on nonurgent ED utilization, while simultaneously adjusting for all factors. Females were 41% more likely to have a nonurgent ED visit (p≤0.0001). Members ages 50-65 were least likely to have a nonurgent ED visit (p≤0.0001). White members had higher odds of having at least one nonurgent ED visit (p≤0.0002). Rural members were 7.7% less likely to have a nonurgent ED visit. Members in the 400%+FPL category were less likely to seek nonurgent care from an ED (p≤0.0001). A nonurgent ED visit occurs when care is sought at an ED that could have been handled in a primary care setting. Approximately 30-50% of all ED visits in the United States are considered nonurgent. This study supports the need to determine factors associated with misuse of ED services for nonurgent care. Demographic factors significantly impacting nonurgent ED utilization include gender, age, race/ethnicity, urbanicity and percent of the FPL. Results may be useful in ED utilization management efforts.

Connecting Emergency Department Patients to Primary Care.

Inappropriate emergency department (ED) use among Medicaid enrollees is considered a problem because of cost. We developed and evaluated a system change innovation designed to remove system barriers to primary care access for Medicaid patients. Patients who presented to the ED without an identified primary care provider were randomized to the intervention (n = 72) or comparison group (n = 68) for a 12-month study designed to connect these patients to primary care offices. Evaluation was mixed quantitative/qualitative. Significantly more intervention participants attended at least 1 primary care visit 3 months after the intervention (odds ratio [OR], 2.52; 95% confidence interval [CI], 1.06-6.02), though this difference was not significant by 12 months (OR, 1.74; 95% CI, 0.79-3.84). The intervention participants also did not have lower odds of returning to the ED for nonurgent reasons by the 12-month follow-up (OR, 1.27; 95% CI, 0.65-2.48). Patient-reported barriers to attending a primary care appointment were primarily social and health system-related factors. The intervention did not decrease ED visits nor increase primary care use over the 12 months of the study period. The qualitative results provide insight into nonurgent ED utilization by patients with Medicaid, suggesting potential future interventions.

Travel distance and sociodemographic correlates of potentially avoidable emergency department visits in California, 2006-2010: an observational study.

IntroductionUse of the hospital emergency department (ED) for medical conditions not likely to require immediate treatment is a controversial topic. It has been faulted for ED overcrowding, increased expenditures, and decreased quality of care. On the other hand, such avoidable ED utilization may be a manifestation of barriers to primary care access.MethodsA random 10% subsample of all ED visits with unmasked variables, or approximately 7.2% of all ED visits in California between 2006 and 2010 are used in the analysis. Using panel data methods, we employ linear probability and fractional probit models with hospital fixed effects to analyze the associations between avoidable ED utilization in California and observable patient characteristics. We also test whether shorter estimated road distances to the hospital ED are correlated with non-urgent ED utilization, as defined by the New York University ED Algorithm. We then investigate whether proximity of a Federally Qualified Health Center (FQHC) is correlated with reductions in non-urgent ED utilization among Medicaid patients.ResultsWe find that relative to the reference group of adults aged 35–64, younger patients generally have higher scores for non-urgent conditions and lower scores for urgent conditions. However, elderly patients (≥65) use the ED for conditions more likely to be urgent. Relative to male and white patients, respectively, female patients and all identified racial and ethnic minorities use the ED for conditions more likely to be non-urgent. Patients with non-commercial insurance coverage also use the ED for conditions more likely to be non-urgent. Medicare and Medicaid patients who live closer to the hospital ED have higher probability scores for non-emergent visits. However, among Medicaid enrollees, those who live in zip codes with an FQHC within 0.5 mile of the zip code population centroid visit the ED for medical conditions less likely to be non-emergent.ConclusionsThese patterns of ED utilization point to potential barriers to care among historically vulnerable groups, observable even when using rough estimates of travel distances and avoidable ED utilization.Electronic supplementary materialThe online version of this article (doi:10.1186/s12939-015-0158-y) contains supplementary material, which is available to authorized users.

Copayments and Emergency Department Use Among Adult Medicaid Enrollees

A number of state Medicaid programs have recently proposed or implemented new or increased copayments for nonemergent emergency department (ED) visits. Evidence suggests that copayments generally reduce the level of healthcare utilization, although there is little specific evidence regarding the effectiveness of copayments in reducing nonurgent ED use among Medicaid enrollees or other low-income populations. Encouraging efficient and appropriate use of healthcare services will be of particular importance for Medicaid programs as they expand under the Patient Protection and Affordable Care Act. This analysis uses national data from 2001 to 2009 to examine the effect of copayments on nonurgent ED utilization among nonelderly adult enrollees. We find that visits among Medicaid enrollees in state-years where a copayment is in place are significantly less likely to be for nonurgent reasons. Our findings suggest that copayments may be an effective tool for reducing use of the ED for nonurgent care.

Caregiver Low Health Literacy and Nonurgent Use of the Pediatric Emergency Department for Febrile Illness

ObjectiveTo examine the association between caregiver health literacy and the likelihood of a nonurgent emergency department (ED) visit in children presenting for fever. MethodsThis cross-sectional study used the Newest Vital Sign to assess the health literacy of caregivers accompanying children with fever to the ED. Visit urgency was determined by resources utilized during the ED visit. Findings were stratified by race and child age. Chi-square and logistic regression analysis controlling for race were conducted to determine the association between low health literacy and ED visit urgency. ResultsA total of 299 caregivers completed study materials. Thirty-nine percent of ED visits for fever were nonurgent, and 63% of caregivers had low health literacy. Low health literacy was associated with a higher proportion of nonurgent ED visits for fever (44% vs 31%, odds ratio 1.8, 95% confidence interval [CI] 1.1, 2.9). Low health literacy was associated with higher odds of a nonurgent visit in white and Hispanic caregivers but not in black caregivers. In regression analysis, children ≥2 years old had higher odds of a nonurgent visit if caregivers had low health literacy (adjusted odds ratio 2.0; 95% CI 1.1, 4.1); this relationship did not hold for children <2 years old (adjusted odds ratio 0.8; 95% CI 0.4, 1.8). ConclusionsNearly two-thirds of caregivers with their child in the ED for fever have low health literacy. Caregiver low health literacy is associated with nonurgent ED utilization for fever in children over 2 years of age. Future interventions could target health literacy skills regarding fever in caregivers of children ≥2 years.

Primary Care Spatial Density and Nonurgent Emergency Department Utilization: A New Methodology for Evaluating Access to Care

ObjectiveTo determine the spatial and demographic characteristics of pediatric patients who make nonurgent visits (NUVs) to an urban pediatric emergency department (ED). We hypothesized that the rate of NUVs would be inversely associated with the spatial density of primary care providers (PCPs). MethodsA retrospective, cross-sectional analysis was conducted for all visits to Washington, DC’s principal pediatric ED between 2003 and 2006. NUVs were defined by a unique algorithm combining resource allocation, ambulatory-sensitive diagnoses, and billing data. Multivariate linear regression analysis was used to determine the association of PCP density and demographic variables on the spatial rate of NUVs. ResultsOver the 4-year period, 35.1% (52,110) of the 148,314 ED visits by Washington, DC, residents were nonurgent. NUVs were most associated with neighborhood median household income <$40,000 and low spatial density of PCPs. For every 1-unit increase in PCP density, the spatial rate of NUVs decreased by 9%. The odds of a visit being nonurgent were significantly higher for African Americans and Hispanics than for whites (odds ratio [OR] 2.4, 95% confidence interval [CI] 2.19–2.64; and OR 2.6, 95% CI 2.36–2.86, respectively), for patients using public insurance versus private (OR 1.46, 95% CI 1.42–1.50), and for patients age <5 years (OR 2.66, 95% CI 2.60–2.72). ConclusionsLow spatial density of primary care is strongly associated with nonurgent ED utilization. Improving spatial distribution of primary care may decrease ED misuse and improve access to the medical home.

Primary paediatric care models and non-urgent Emergency Department utilization: an area-based cohort study

BackgroundThe aim of this study was to evaluate the association between different primary paediatric practice models (individual, network -affiliated but in separate office-, and group practice) and non urgent utilization of the Emergency Department (ED).MethodsThe data sources were: the 2006 Regional Paediatric Patient files (0-6 years old), the Regional Community-based paediatrician (CBP) file and the 2006 Emergency Information System. We recorded and studied the ED visits of children, excluding planned ED visits, visits for trauma/poisoning and those that were assigned non deferrable/critical triage codes. A multivariate logistic regression was applied to estimate the adjusted odds ratio of an ED visit. The exposure was the type of paediatric practice that served the child: individual, network or group practice. Various characteristics of the child were considered.ResultsThe cohort was composed of 293,662 children. In the 2006, 43,347 ED visits occurred (147.6 per 1000). Multivariate logistic models showed lower ED use for group paediatrician patients (OR 0.84; 95%CI 0.73-0.96) and for network paediatrician patients (OR 0.92; 95%CI 0.85-1.00) compared to patients served by an individual practice.ConclusionsThis study shows that there is a weak association between the type of paediatrician primary practice and emergency department use. Our results highlight the necessity to continue to improve the organization of paediatrician primary practice, in order to increase patient access to primary paediatric care.

Quality of Primary Care and Subsequent Pediatric Emergency Department Utilization

Our objective was to determine whether parent-reported, high-quality primary care was associated with decreased nonurgent pediatric emergency department utilization. A retrospective analysis of prospectively collected data for a cohort of children from the 2000-2001 and 2001-2002 Medical Expenditure Panel Survey panels was performed. Baseline parent-reported quality of primary care with respect to family-centeredness, timeliness, and realized access (a measure of the child's ability to receive necessary care and referrals) was assessed by using composite scores from the Consumer Assessment of Healthcare Providers and Systems survey. The primary outcomes were the numbers of subsequent nonurgent and urgent emergency department visits per child. Of 8823 children included, 70.0% rated family-centeredness, 88.2% rated realized access, and 55.6% rated timeliness as high quality. After adjustment for demographic factors and health status, high-quality family-centeredness was associated with a 42% reduction in nonurgent emergency department visits for publicly insured children and a 49% reduction for children < or = 2 years of age. Greater realized access was associated with a 44% reduction in nonurgent emergency department visits for children 3 to 11 years of age and a 56% reduction for children > or = 12 years of age. Greater realized access was also associated with decreased nonurgent emergency department visits for publicly and privately insured children (37% and 35%, respectively). There was no significant association between timeliness and nonurgent emergency department utilization, nor was any quality-of-care domain associated with urgent emergency department utilization. Parent-reported, high-quality family-centeredness and a high level of realized access to primary care were associated with decreased subsequent nonurgent emergency department visits for children. Parent reports of health care quality in these domains provide important complementary information on health care quality.

Characteristics of nonurgent emergency department use in the first 3 months of life.

To determine the characteristics of nonurgent emergency department (ED) visits in the first 3 months of life. The study cohort consisted of full-term newborns admitted to and discharged from one newborn nursery from September 1, 1992, to May 1, 1994. All visits in the first 90 days of life to one large urban ED were analyzed to determine whether they were nonurgent, based on history of present illness and final diagnosis or disposition. The principal outcomes of interest were the frequency and pattern of nonurgent ED visits. Risk factors for nonurgent ED use were also studied. A total of 2137 patients with 965 ED visits were analyzed; 20.4% of the patients had nonurgent visits, and 60.1% of all visits were nonurgent. Of all patients with nonurgent visits, 24.1% had more than one. Younger maternal age, Medicaid, maternal parity, and nonwhite race all resulted in increased nonurgent ED use. One third of all ED visits were made when the primary care physician's offices were open, and 57.6% of these visits were nonurgent. Maternal and economic factors affected nonurgent ED utilization. Other critical factors still need to be explored. Interventions focused on decreasing nonurgent ED use in early infancy should be targeted at patients with the identified risk factors.

The use of hospital emergency departments for nonurgent health problems: a national perspective.

The use of the hospital emergency department (ED) for nonurgent health problems has been a subject of considerable controversy, in part because there is no widely accepted definition of "nonurgent." Elimination or substantial reduction in nonurgent ED use is frequently offered as a strategy for reducing health expenditures. Previous studies, often limited to individual hospitals or communities, have limited generalizability and do not permit examination of multiple factors likely to influence nonurgent ED utilization or examination of ED use for nonurgent problems in the context of overall outpatient utilization. This analysis of the 1987 National Medical Expenditure Survey (NMES) provides a nationally representative examination of nonurgent ED utilization that describes the frequency of ED use for nonurgent problems, characteristics of individuals that are associated with an increased likelihood of nonurgent ED use, the use of other outpatient physician services, and expenditures associated with nonurgent ED visits.
