Avoidable Emergency Department Visits Research Articles

Geographic proximity to primary care providers as a risk-assessment criterion for quality performance measures.

Previous studies have found a mixed association between Patient-Centered Medical Home (PCMH) designation and improvements in primary care quality indicators, including avoidable pediatric emergency department (ED) encounters. Whether these associations persist after accounting for the geographic locations of providers relative to where patients reside is unknown. To examine the association between geographic proximity to primary care providers versus hospitals and risk of avoidable and potentially avoidable ED visits among children with pre-existing diagnosis of attention-deficit/hyperactivity disorder or asthma. Retrospective cohort study of a panel of pediatric Medicaid claims data from the South Carolina from 2016-2018 for 2,959 beneficiaries having a pre-existing diagnosis of attention-deficit/hyperactivity disorder (ADD, ages 6-12) and 6,390 beneficiaries with asthma (MMA, ages 5-18), as defined using Healthcare Effectiveness Data and Information Set (HEDIS) performance measures. We calculated differences in avoidable and potentially avoidable ED visits by the beneficiary's PCMH attribution type and in relation to differences in proximity to their primary care providers versus hospitals. Outcomes were defined using the New York University Emergency Department Algorithm (NYU-EDA). Differences in ED visit risk were assessed using generalized estimation equations and compared using marginal effects models. The 2.4 percentage point reduction in risk of avoidable ED visits among children in the ADD cohort who attended a PCMH versus those who did not increased to 3.9 to 7.2 percentage points as relative proximity to primary care providers versus hospitals improved (p < 0.01). Children in the ADD and MMA cohorts that were enrolled in a medical home, but did not attend one for primary care services exhibited a 5.4 and 3.0 percentage point increase in avoidable ED visit compared to children who were unenrolled and did not attend medical homes (p < 0.05), but these differences were only observed when geographic proximity to hospitals was more convenient than primary care providers. Mixed findings were observed for potentially avoidable visits. In several health care performance evaluations, patient-centered medical homes have not been found to reduce differences in hospital utilization for conditions that are treatable in primary care settings among children with chronic illnesses. Analytical approaches that also consider geographic proximity to health care services can identify performance benefits of medical homes. Expanding risk-adjustment models to also include geographic data would benefit ongoing quality improvement initiatives.

Inappropriate and potentially avoidable emergency department visits of Swiss nursing home residents and their resource use: a retrospective chart-review

BackgroundEmergency department (ED) visits for nursing home residents lead to higher morbidity and mortality. Therefore, inappropriate visits (for conditions treatable elsewhere) or potentially avoidable visits (those avoidable through adequate chronic care management) must be minimized. This study aimed to investigate factors and resource consumption patterns associated with inappropriate and potentially avoidable visits in a Swiss tertiary hospital.MethodsThis is a single-center retrospective chart review in an urban Swiss university hospital ED. A consecutive sample of 1276 visits by nursing home residents (≥ 65 years old), recorded between January 1, 2015 and December 31, 2017 (three calendar years) were included. Case characteristics were extracted from ED electronic documentation. Appropriateness was assessed via a structured Appropriateness Evaluation Protocol; potentially avoidable visits—measured as ambulatory-care sensitive conditions (ACSCs)—were analyzed separately. Inter-group differences concerning ED resource use were tested respectively with chi-square or Wilcoxon rank sum tests. To identify predictors of inappropriate or potentially-avoidable visits, we used multivariable logistic regression analysis.ResultsSix percent of visits were rated as inappropriate: they had lower triage levels (OR 0.55 [95%-CI 0.33-0.92], p=0.024) and, compared to ambulance calls, they had higher odds of initiation via either patient-initiated walk-in (OR 3.42 [95%-CI 1.79-6.55], p≤0.001) or GP referrals (OR 2.13 [95%-CI 1.16-3.90], p=0.015). For inappropriate visits, overall ED resource use was significantly lower (median 568 vs. 1403 tax points, p≤0.001). Of all visits included, 29% were due to (often potentially-avoidable) ACSCs. In those cases, compared to ambulance initiation, odds of being potentially-avoidable were considerably lower for walk-in patients (OR 0.46 [95%-CI 0.27-0.77], p=0.004) but higher for GP referrals (OR 1.40 [95%-CI 1.00-1.94], p=0.048). Nurse work (93 tax points vs. 64, p≤0.001) and laboratory resource use (334 tax points vs. 214, p≤0.001) were higher for potentially-avoidable ED visits.ConclusionsWe revealed substantial differences between the investigated groups. While nearly one third of ED visits from nursing homes were potentially avoidable, inappropriate visits were lower in numbers and not resource-intensive. Further research is required to differentiate potentially avoidable visits from inappropriate ones and to determine these findings’ public health implications.

Decomposing Differences in Risk-Adjusted Rates of Emergency Department Visits Between Micropolitan and Urban Nursing Homes.

Nursing homes (NHs) in micropolitan areas are reported to have different facility and market factors than urban NHs, but how these factors contribute to differences in emergency department (ED) visits remains unknown. This study examined and quantified sources of micropolitan-urban differences in NH risk-adjusted rates of any ED visit, ED without hospitalization or observation stay (outpatient ED), and potentially avoidable ED (PAED) visits of long-stay residents. The 2011-2013 national Medicare claims and NH Minimum Data Set (MDS) 3.0 were analyzed. We implemented generalized estimating equation models to examine micropolitan-urban differences in ED rates and Blinder-Oaxaca decompositions to quantify the contributions of NH and market factors. The study cohort included 12,883 unique privately owned, freestanding NHs from urban and micropolitan areas. Quarterly risk-adjusted rates of any ED visits, outpatient ED visits, and PAED visits were calculated from Medicare claims and MDS. NH and market characteristics were extracted from the Certification And Survey Provider Enhanced Reporting and Area Health Resources File. Over the study period, risk-adjusted rates averaged 10.2%, 3.4%, and 3.3% for any ED, outpatient ED, and PAED visits, respectively. Compared with urban NHs, micropolitan NHs reported similar rates of any ED, but significantly higher rates of outpatient ED and PAED (β= 0.20% and 0.27%; both P < .05). Observable differences in NH characteristics (eg, number of beds, percentage Medicare or Medicaid residents, and employment of nurse practitioners and physician assistants) explained more than 20% of the micropolitan-urban differences in rates of outpatient ED and PAED visits; market factors (mainly Medicare Advantage penetration) explained about 46% of the differences in rates of outpatient ED visits. Compared with urban NHs, micropolitan NHs tend to utilize more avoidable emergency care that can be partially explained by facility size, payer mix, use of nurse practitioners and physician assistants, and market structure.

Association Between Self-reported Health-Related Social Needs and Acute Care Utilization Among Older Adults Enrolled in Medicare Advantage

There is increased focus on identifying and addressing health-related social needs (HRSNs). Understanding how different HRSNs relate to different health outcomes can inform targeted, evidence-based policies, investments, and innovations to address HRSNs. To examine the association between self-reported HRSNs and acute care utilization among older adults enrolled in Medicare Advantage. This cross-sectional study used data from a large, national survey of Medicare Advantage beneficiaries to identify the presence of HRSNs. Survey data were linked to medical claims, and regression models were used to estimate the association between HRSNs and rates of acute care utilization from January 1, 2019, through December 31, 2019. Self-reported HRSNs, including food insecurity, financial strain, loneliness, unreliable transportation, utility insecurity, housing insecurity, and poor housing quality. All-cause hospital stays (inpatient admissions and observation stays), avoidable hospital stays, all-cause emergency department (ED) visits, avoidable ED visits, and 30-day readmissions. Among a final study population of 56 155 Medicare Advantage beneficiaries (mean [SD] age, 74.0 [5.8] years; 32 779 [58.4%] women; 44 278 [78.8%] White; and 7634 [13.6%] dual eligible for Medicaid), 27 676 (49.3%) reported 1 or more HRSNs. Health-related social needs were associated with statistically significantly higher rates of all utilization measures, with the largest association observed for avoidable hospital stays (incident rate ratio for any HRSN, 1.53; 95% CI, 1.35-1.74; P < .001). Compared with beneficiaries without HRSNs, beneficiaries with an HRSN had a 53.3% higher rate of avoidable hospitalization (incident rate ratio, 1.53; 95% CI, 1.35-1.74; P < .001). Financial strain and unreliable transportation were each independently associated with increased rates of hospital stays (marginal effects of 26.5 [95% CI, 14.2-38.9] and 51.2 [95% CI, 30.7-71.8] hospital stays per 1000 beneficiaries, respectively). All HRSNs, except for utility insecurity, were independently associated with increased rates of ED visits. Unreliable transportation had the largest association with increased hospital stays and ED visits, with marginal effects of 51.2 (95% CI, 30.7-71.8) and 95.5 (95% CI, 65.3-125.8) ED visits per 1000 beneficiaries, respectively. Only unreliable transportation and financial strain were associated with increased rates of 30-day readmissions, with marginal effects of 3.3% (95% CI, 2.0%-4.0%) and 0.4% (95% CI, 0.2%-0.6%), respectively. In this cross-sectional study of older adults enrolled in Medicare Advantage, self-reported HRSNs were common and associated with statistically significantly increased rates of acute care utilization, with variation in which HRSNs were associated with different utilization measures. These findings provide evidence of the unique association between certain HRSNs and different types of acute care utilization, which could help refine the development and targeting of efforts to address HRSNs.

Avoidable emergency department visits for rabies vaccination

BackgroundAdministering subsequent doses of rabies vaccine is not a medical emergency and does not require access to emergency department (ED) services. This study reviewed ED visits for rabies postexposure prophylaxis (PEP) to identify avoidable ED visits for subsequent rabies vaccination. MethodsThis retrospective study included patients who received human rabies immune globulin (HRIG) or rabies vaccine at 15 EDs of a multi-hospital health system from 2016 to 2018. All ED visits were classified as initial or non-initial healthcare visits after animal exposure. Emergency department visits for non-initial healthcare were classified as necessary (HRIG administration, worsening symptoms, other emergent conditions, or vaccination during a natural disaster) or avoidable (rabies vaccination only). ResultsThis study included 145 patients with 203 ED visits (113 initial and 90 non-initial healthcare visits). Avoidable ED visits were identified for 19% (28 of 145) of patients and 66% (59 of 90) of ED visits for non-initial healthcare. Contributing factors for avoidable ED visits were suboptimal ED discharge instructions to return to the ED for vaccination (n = 20 visits) and patients' inability to coordinate outpatient follow-up (n = 17 visits). Patients with previous avoidable ED visits had a 73% probability for unnecessarily returning to the ED for vaccination. The average number of avoidable ED visits observed per patient was 0.41 (95% CI = 0.25 to 0.56). Since the Centers for Disease Control and Prevention reports that 30,000 to 60,000 Americans initiates rabies PEP each year, we estimate that 7500 to 33,600 avoidable ED visits occur for rabies vaccination in the US each year. ConclusionsOne of 5 patients who received rabies PEP in the ED had avoidable ED visits for subsequent rabies vaccination. This study highlights systemic lack of coordination following ED discharge and barriers to accessing rabies vaccine.

Residual Confounding in Health Plan Performance Assessments: Evidence From Randomization in Medicaid.

Risk adjustment is used widely in payment systems and performance assessments, but the extent to which it distinguishes plan or provider effects from confounding due to patient differences is typically unknown. To assess the degree to which risk-adjusted measures of health plan performance adequately adjust for the variation across plans that arises because of differences in patient characteristics (residual confounding). Comparison between plan performance estimates based on enrollees who made plan choices (observational population) and estimates based on enrollees assigned to plans (randomized population). Natural experiment in which more than two thirds of a state's Medicaid population in 1 region was randomly assigned to 1 of 5 plans. 137933 enrollees in 2013 to 2014, of whom 31.1% selected a plan and 68.9% were randomly assigned to 1 of the same 5 plans. Annual total spending (that is, payments to providers), primary care use, dental care use, and avoidable emergency department visits, all scored as plan-specific deviations from the "average" plan performance within each population. Enrollee characteristics were appreciably imbalanced across plans in the observational population, as expected, but were not in the randomized population. Annual total spending varied across plans more in the observational population (SD, $147 per enrollee) than in the randomized population (SD, $70 per enrollee) after accounting for baseline differences in the observational and randomized populations and for differences across plans. On average, a plan's spending score (its deviation from the "average" performance) in the observational population differed from its score in the randomized population by $67 per enrollee in absolute value (95% CI, $38 to $123), or 4.2% of mean spending per enrollee (P= 0.009, rejecting the null hypothesis that this difference would be expected from sampling error). The difference was reduced modestly by risk adjustment to $62 per enrollee (P= 0.012). Residual confounding was similarly substantial for most other performance measures. Further adjustment for social factors did not materially change estimates. Potential heterogeneity in plan effects between the 2 populations. Residual confounding in risk-adjusted performance assessments can be substantial and should caution policymakers against assuming that risk adjustment isolates real differences in plan performance.

Factors associated with avoidance of emergency department visits in Portugal during the pandemic

Abstract Background Avoiding an emergency department (ED) visit risks irreversible negative consequences for patients' health. EDs are a frequent access point to the Portuguese health system. Previous studies have shown that patients may avoid visiting ED during the pandemic. This study aims to identify factors associated with avoidance of ED visits in Portugal during the COVID-19 pandemic. Methods We used data from a community-based survey, “COVID-19 Barometer: Social Opinion”, which includes healthcare utilisation, health status, and risk perception in Portugal from 11th April 2020 to 16th April 2021. We included respondents that reported having needed ED care. Data were collected on sociodemographics, health status (comorbidities, mental health), risk perception (COVID-19 and complications), level of trust in health services and self-assessment of the severity of the reason for ED visit. The outcome of interest was the decision to avoid ED care. We used logistic regression to identify factors associated with the decision to avoid ED. Results Preliminary data showed that 914 respondents reported needing ED care (74.8% female; mean age 43 years). From those, 224 (25%) decided to avoid ED care. ED visits avoidance was higher during lockdowns (28%). People reporting specific comorbidities (cardiac, autoimmune, respiratory) avoided ED more than those without them. Perception of no severe reason for ED visit, poor mental health, perception of higher risk of COVID-19 and complications, and low trust in health services response to the pandemic were associated with higher odds of ED visit avoidance. Conclusions People avoiding ED visits represented a considerable share. The decision to avoid ED visit was associated with clinical characteristics, but the perception of risk and assessment of the context and health system response also played a role in decision making. Key messages The effect of avoided ED visits on health should be a research and policy concern. People with certain comorbidities or perception of high risk of COVID-19 and complications may be closely monitored.

85 Differences in Emergency Department Use Among Cancer Patients Who Have Used an Oncology Urgent Care Clinic

Potentially avoidable emergency department (ED) visits constitute a large share of health care spending in patients recently diagnosed with cancer. As an alternative to the ED, health systems have created oncology urgent care clinics (UCC) to treat common acute care needs. Prior work in our urban university health system found slowed growth in total ED visits through 2016 after the start of our UCC despite limited UCC use. A more direct analysis of differences in ED visits after UCC use would identify whether patients reverted to using the ED after the UCC.

Evaluating the utility of rule OP-35 to define preventability of ED visits for oncology patients at an academic cancer center.

272 Background: Rule OP-35, which characterizes treatment-related complications of patients receiving outpatient chemotherapy that result in a potentially avoidable emergency department (ED) visit or hospitalization, was developed to encourage practices to build treatment models that reduce such events. However, defining visits as potentially avoidable based on symptoms may not capture the complexity of caring for oncology patients. We aim to evaluate the effectiveness of OP-35 in identifying preventable ED visits by real world standards at an academic institution. Methods: A retrospective analysis was performed reviewing ED visits at the Sidney Kimmel Cancer Center (SKCC) at Thomas Jefferson University for oncology patients from 10/1/2020 to 1/31/2021. Each patient received care at SKCC had received intravenous or oral chemotherapy in the preceding 30 days, and each encounter was classified as potentially avoidable by OP-35 criteria. Two investigators independently conducted chart reviews to determine whether these visits were potentially avoidable, recording whether the patient attempted to contact their care team prior to the ED encounter and assessing if the concern could have been managed in a timely manner in an outpatient setting. The two records were then compared, and the principal investigator served as an arbiter for determining if a visit was potentially avoidable in instances where the investigators disagreed. Results: We reviewed 144 total encounters and excluded events from patients with either acute leukemia or breast cancer on hormone therapy only, leaving 107 encounters for analysis. After evaluating the clinical circumstances, we determined that 29% of these ED encounters were potentially avoidable. Applying New York University Emergency Department Algorithm (NYU-EDA) criteria, 69% of encounters were considered potentially avoidable. Patients called for advice before seeking ED care in 53% of unavoidable encounters compared to 26% of potentially avoidable encounters. An additional 14% of visits deemed unavoidable were from patients sent directly from clinic. For potentially avoidable encounters, 60% of patients were discharged directly from the ED. In comparison, 8% of unavoidable encounters led to discharge from the ED. Pain was the most common reason for encounters and 53% of these visits were considered potentially avoidable. Conclusions: We found that approximately 30% of ED encounters deemed avoidable by OP-35 criteria were considered potentially avoidable following clinician review. In the majority of cases patients were referred to the ED following initial outpatient attempts at management. NYU-EDA criteria for preventability did not correlate with OP-35 nor clinician consensus regarding potentially avoidable encounters. More work remains in refining tools to identify potentially avoidable ED visits for oncology patients.

Changes in Primary Care Telehealth Use and Impact on Acute Care Visits for Ambulatory Care‐Sensitive Conditions during COVID‐19

Research ObjectiveThe COVID‐19 pandemic forced a dramatic shift from in‐person care to telehealth, with an overall decrease in outpatient utilization. These changes particularly stressed outpatient care delivery and may have resulted in decreased availability and access to primary care for patients, potentially increasing otherwise avoidable emergency department (ED) visits and hospitalizations. One commonly used indicator of primary care access and quality is acute care visits for ambulatory care‐sensitive conditions (ACSCs), such as for pneumonia, uncontrolled diabetes, or congestive heart failure exacerbations. Our study examined differences in telehealth adoption across practices and evaluated the association between telehealth adoption and ACSC visits.TABLE 1Differences‐in‐differences model of practice telemedicine conversion rate on acute care visits for acute and chronic ACSCsAcute ACSC aOR (95% CI)Chronic ACSC aOR (95% CI)Telemedicine tertile (mean telemedicine conversion rate)Low (9%)refrefMedium (30%)0.98 (0.91–1.07)0.98 (0.76–1.26)High (66%)1.07 (0.98–1.17)1.14 (0.86–1.50)Study DesignWe conducted a retrospective study of claims data from a large commercial insurer in Michigan. We first profiled telehealth adoption by primary care practices during March–July 2020. We defined a practice's “telehealth conversion rate” as the proportion of visits conducted via telehealth during this period compared to the total number of visits during the same period in 2019. Then, to enable comparison between groups at a time when both outpatient and acute care visits were in flux, we used a differences‐in‐differences (DID) model to determine whether varying levels of primary care telehealth conversion were associated with differences in acute care visits (ED visits and hospitalizations) for ACSCs from June–September 2020. We examined visit rates for acute and chronic ACSCs separately, controlling for practice size, in‐person visit volume, and zip code‐level attributes as well as patient characteristics (age, gender, comorbidities). We performed sensitivity analyses using varying definitions of telemedicine conversion rates and multiple model specifications.Population StudiedSix million Blue Cross Blue Shield of Michigan beneficiaries across 3780 primary care practices from January 2019 to September 2020.Principal FindingsAverage primary care practice telehealth conversion rate was 25% (median 10%), and 29% of practices had no telehealth claims identified. Practices that did not adopt telehealth tended to be smaller and were more likely to be in rural areas. We found no significant differences in the rate of ED visits and hospitalizations for ACSCs by practice‐level telemedicine conversion tertile after adjusting for practice case‐mix, as shown in Table 1. Sensitivity analyses showed similar results.ConclusionsBeneficiaries within a large commercial payer experienced rapid shifts from in‐person to telehealth for their primary care, though telehealth adoption was not evenly distributed, with smaller and more rural practices being less likely to adopt telemedicine. These changes did not seem to obviously help or harm patients as ED visits and hospitalizations for ACSCs were similar across groups.Implications for Policy or PracticeWidespread substitution of telehealth for in‐person care had little impact on cost of care with respect to avoidable ED visits and hospitalizations in the near‐term. Additional research should continue to monitor this trend as health care utilization stabilizes beyond the pandemic.Primary Funding SourceUniversity of Michigan Institute for Health Policy and Innovation.

17 Telemedicine For Veterans in the Setting of the COVID-19 Pandemic: Lessons Learned From VISN 8’S Clinical Contact Center (A Virtual Urgent Care) in Avoiding Emergency Department Visits

The onset of the COVID-19 pandemic forced the health care industry to consider telemedicine as the primary modality for health care with focus on value and ease for providers and patients alike to achieve outcomes similar to face-to-face primary care (PC), urgent care (UC), and emergency department (ED) visits. It remained unclear if telemedicine visits actually achieved first contact resolution (FCR), fully meeting the patients’ needs through their virtual care experience. At a time when Florida ranked #3 in its COVID-19 census, Veterans needed access to timely care to answer their concerns and questions.

Factors Associated With Avoidable Emergency Department Visits in Broward County, Florida.

BackgroundImproper utilization of emergency departments (EDs) in the United States is an issue that places a large burden on the healthcare system. Previous studies have shown that differences in race, gender, and income level have been associated with avoidable ED visits. Broward County, Florida, is diverse with people from many different socioeconomic backgrounds. The objective of this study is to determine the impact that race/ethnicity, gender, and payment methods have on the rates of avoidable ED visits at hospitals in Broward County, Florida.MethodsThis study utilized a dataset from the Broward Regional Health Planning Council that included ED visits in Broward County in 2019. Secondary data analysis was conducted utilizing a one-way analysis of variance (ANOVA) with post-hoc analysis to compare the proportions of non-emergent, emergent primary care-treatable, and emergent preventable ED visits amongst different race/ethnicities, genders, and payment/insurance methods.ResultsCompared to non-Hispanic white patients, non-Hispanic black and Hispanic patients had higher mean rates of non-emergent ED visits. Women had greater mean rates compared to men for non-emergent ED visits; males had higher mean rates than females for emergent primary care-treatable and emergent preventable. Patients covered by Medicaid had greater mean rates of non-emergent and emergent primary care-treatable visits compared to patients using other payment or insurance methods.ConclusionsThis study identified demographics within Broward County associated with avoidable ED visits. To reduce the burden of ED overutilization on the healthcare system, healthcare providers must better educate the at-risk populations about proper ED use. In addition, a comprehensive assessment of social determinants of health in patients overutilizing the ED will allow for better alignment of resources and policy changes to improve healthcare access and community health.

Nursing home performance in a trial to reduce hospitalizations: Implications for future trials.

Experience in trials of implementing quality improvement (QI) programs in nursing homes (NHs) has been variable. Understanding the characteristics of NHs that demonstrate improvements during these trials is critical to improving NH care. Secondary analysis of a randomized controlled trial of implementation of a QI program to reduce hospital transfers. Seventy-one NHs that completed the 12-month trial INTERVENTION: Implementation included distance-learning strategies, involvement of a champion, regular submission of data on hospitalizations and root cause analyses of transfers, and training, feedback and support. Primary outcomes included all-cause and potentially avoidable hospitalizations and emergency department (ED) visits per 1000 NH resident days, and the percentage of residents readmitted in 30-days. We compared multiple other variables that could influence effective program implementation in NHs in the highest versus lowest quartile of changes in the primary outcomes. The 18 high-performing NHs had significant reductions in hospitalization and ED visits, whereas the 18 NHs in the low-performing group had increases. The difference in changes in each outcome varied between a reduction of 0.75 and 2.30 events relative to a NH with a census of 100; the absolute difference in 30-day readmissions was 19%. None of the variables we examined reached significance after adjustment for multiple comparisons between the groups. There was no consistent pattern of differences in nonprofit status, nursing staffing, and quality ratings. Our experience and reviews of other NH trials suggest that key factors contributing to successful implementation QI programs in NHs remain unclear. To improve NH care, implementation trials should account for intervention fidelity and factors that have not been examined in detail, such as degree and nature of leadership support, financial and regulatory incentives, quality measures, resident and family perspectives, and the availability of onsite high-quality medical care and support of the medical director.

Outcomes Associated With State Policies Enabling Provision of Oral Health Services in Medical Offices Among Medicaid-enrolled Children.

To increase receipt of preventive oral health services (POHS), all state Medicaid programs have enacted policies to encourage nondental providers to deliver POHS in medical offices. This study examined if these Medicaid policies improved oral health, as measured by reductions in dental visits with treatment and preventable emergency department (ED) visits for nontraumatic dental conditions (NTDC). Using data on children aged 6 months to up to 6 years from 38 state Medicaid programs during 2006-2014, we used a generalized difference-in-differences estimation approach to examine the probability of a child having, in a year, any dental visits with caries-related treatment and any ED visits for NTDC, conditional on length of policy enactment. Models included additional child-level and county-level characteristics, state and year fixed effects, probability weights, and clustered standard errors. Among a weighted sample of 45,107,240 child/year observations, 11.7% had any dental visits with treatment and 0.2% had any ED visits for NTDC annually. Children in states with and without medical POHS policies had similar odds of having any dental visits with treatment, regardless of length of policy enactment. Children in states with medical POHS policies enacted for one or more years had significantly greater odds of having any ED visits for NTDC (P<0.05). State policies making POHS available in medical offices did not affect rates of dental visits with caries-related treatment, but were associated with increased rates of potentially avoidable ED visits for NTDC. Findings suggest that many young Medicaid-enrollees lack access to dentists.

Integrated care effectiveness for adults with co-occurring disorders

PurposeThis study examined effectiveness of an integrated care program on emergency department visits within a longitudinal sample of patients with both primary care and behavioral health diagnoses.Design/methodology/approachPatients with co-occurring disorders enrolled in an integrated care clinic and were followed over time to determine whether participation in the clinic, including engagement in wellness/peer services, predicted decreases in Emergency Department (ED) use. Associations between socio-demographic characteristics of patients and ED use were also analyzed.FindingsAfter 6 months, clinic patients had decreases in ED use that continued for twelve months, albeit to a lesser degree. Demographics and program services were not related to ED use; however, multiple associations existed between high ED utilizers, severe mental illness (SMI), substance use disorders (SUD) and non-retention in services.Research limitations/implicationsThe study lacked a comparison group and there was no distinction between avoidable and unavoidable ED visits. A small sample size across time points led to inconclusive post hoc findings.Originality/valueThis study explored effectiveness of primary care integration into a behavioral health clinic for persons with multiple morbidities. Although initial decreases in ED visits were present, results indicate that these models may not be effective for persons with SMI or SMI/SUD who are already high ED users. This study provides support for integrated care in reducing ED use among persons with multiple morbidities and calls for further research on designing effective integrated models for persons with SMI and SUD.

The Medicaid expansion did not crowd out access for medicaid recipients with disabilities in Oregon

BackgroundThe Affordable Care Act (ACA) substantially increased the number of Medicaid enrollees, which could have reduced access to health care services for those already on Medicaid before the expansion. ObjectiveTo examine the association of the ACA expansion on health care access and utilization for adults ages 18–64 years who have qualified for Supplemental Security Income (SSI) in Oregon. MethodsWe used Oregon Medicaid claims and enrollment data from 2012 to 2015 and information from the American Community Survey and the Local Area Unemployment Statistics. Multivariate regressions compared changes in health care access and utilization before and after the expansion among Medicaid recipients who qualified for SSI across counties in Oregon with higher and lower Medicaid enrollment increases due to the expansion. Health care access and utilization outcome measures included: primary care visits, non-behavioral health outpatient visits, behavioral health outpatient visits, emergency department (ED) visits and potentially avoidable ED visits. ResultsThe Medicaid expansion led to an uneven increase in Medicaid enrollment across Oregon’s counties (mean increase from the first quarter of 2012 to the third quarter of 2015: 12.4% points; range: 7.3 to 18.6% points). Access and utilization outcomes for SSI Medicaid recipients were mostly unaffected by differential enrollment increases. ED visits increased more in counties with a larger Medicaid enrollment increase (estimate: 1.8, p < 0.05), but adjusting for pre-expansion trends eliminated this association. ConclusionsWe did not find evidence that an increase in Medicaid enrollment due to the ACA negatively impacted access and utilization for adult Medicaid recipients on SSI, who were eligible for Medicaid prior to expansion.

Rural-Urban Differences in Nursing Home Risk-adjusted Rates of Emergency Department Visits: A Decomposition Analysis.

Higher risk-adjusted rate of emergency department (ED) visits might reflect poor quality of nursing home (NH) care; however, existing evidence is limited regarding rural-urban differences in ED rates of NHs, especially for long-stay residents. To determine and quantify sources of rural-urban differences in NH risk-adjusted rates of any ED visit, ED without hospitalization or observation stay (outpatient ED), and potentially avoidable ED visits (PAED) of long-stay residents. We calculated quarterly NH risk-adjusted rates using 2011-2013 national Medicare claims and Minimum Data Set 3.0, and then implemented Generalized Estimating Equation models to examine rural-urban differences in ED rates and Blinder-Oaxaca decomposition to quantify the contributions of NH and market factors. Privately owned, free-standing NHs in the United States (N=13,260). Over the study period, risk-adjusted rates averaged 9.8% for any ED, 3.3% for outpatient ED, and 3.2% for PAED. Compared with urban NHs, rural NHs were associated with significantly lower rates of any ED, outpatient ED, and PAED (β=-1.67%, -0.44%, and -0.28%; all P<0.01). Observable differences in market factors (nursing home bed concentration, hospital beds, and the existence of a critical access hospital) explained about half of the rural-urban differences in rates of any ED and PAED, but not outpatient ED. Decomposition analyses suggested that lower ED rates in rural NHs appear to be related to market availability of hospital resources. Policymakers may focus on not only reducing unnecessary ED visits but also ensuring equitable hospital access in rural areas.

Can Home Palliative Care services reduce Emergency Department visits? Piedmont Experience, 2013-2018

Abstract Background Home-based Palliative Care (HPC) ensures multi-disciplinary medical, nursing, rehabilitation and psychological assistance for people with severe disabilities or with progressive end-stage disorders like cancer, promoting the continuity of care in home setting. Emergency Department (ED) visits in palliative care patients are considered an indicator of poor quality in home care services, since ED visits in these patients are not essential and potentially avoidable. There is still no agreement in literature about the efficacy of HPC in reducing the use of ED. However, recent studies demonstrated that HPC increases patient satisfaction while reducing use of medical services like ED, symptom burden and medical costs. The objective of this study was to evaluate if patients assisted by HPC have a reduction of ED visits compared to the 90-day period before HPC admission. Methods A retrospective study using the administrative regional database of Piedmont (Italy) was conducted on the cohort of 4433 patients admitted to HPC from 2013 to 2018. ED visits during period A (90-days before HPC) and period B (during HPC) were compared for each patient, taking into account avoidable or unavoidable visits based on triage examination. Results During period A, patients had 2880 ED visits, 1934 were considered avoidable (67%). During period B, 2050 ED visits were recorded, 994 were considered avoidable (48%). Patients receiving HPC had a reduction of overall ED visits (IRR 0.87, IC 95% 0.82-0.92) as well as avoidable ED visits (IRR 0.63, IC 95% 0.58-0.67). Unavoidable ED visits increased during HPC (IRR 1.36, IC 95% 1.24-1.49), as a consequence of disease progression. Conclusions Home-based Palliative Care is associated with a significant reduction of the use of overall Emergency Department visits (-13%) and ED avoidable visits (-37%). Since it reduces medical care costs and burden of patients and caregivers at the end of life, Home-based Palliative Care delivery should be increased. Key messages Home-based Palliative Care is associated with a reduction of the use of overall Emergency Department visits and avoidable ED visits, reducing medical care costs and burden of patients and caregivers. Home-based Palliative Care delivery should be encouraged and increased, aiming to an early enrolment as well as an increase of the patients.

Predictors and trajectories of ED visits among patients receiving palliative home care services: findings from a time series analysis (2013-2017)

BackgroundCurrent policies recommend integrating home care and palliative care to enable patients to remain at home and avoid unnecessary hospital admission and emergency department (ED) visits. The Italian health care system had implemented integrated palliative home care (IHPC) services to guarantee a comprehensive, coordinated approach across different actors and to reduce potentially avoidable ED visits. This study aimed to analyze the trajectories of ED visit rates among patients receiving IHPC in the Italian healthcare system, as well as the association between socio-demographic, health supply, and clinical factors.MethodsA pooled, cross-sectional, time series analysis was performed in a large Italian region in the period 2013–2017. Data were taken from two databases of the official Italian National Information System: Home Care Services and ED use. A clinical record is opened at the time a patient is enrolled in IHPC and closed after the last service is provided. Every such clinical record was considered as an IHPC event, and only ED visits that occurred during IHPC events were considered.ResultsThe 20,611 patients enrolled in IHPC during the study period contributed 23,085 IHPC events; ≥1 ED visit occurred during 6046 of these events. Neoplasms accounted for 89% of IHPC events and for 91% of ED visits. Although there were different variations in ED visit rates during the study period, a slight decline was observed for all diseases, and this decline accelerated over time (b = − 0.18, p = 0.796, 95% confidence interval [CI] = − 1.59;1.22, b-squared = − 1.25, p < 0.001, 95% CI = -1.63;-0.86). There were no significant predictors among the socio-demographic factors (sex, age, presence of a non-family caregiver, cohabitant family members, distance from ED), health supply factors (proponent of IHPC) and clinical factors (prevalent disorder at IHPC entry, clinical symptoms).ConclusionOur results show that use of ED continues after enrollment in IHPC, but the trend of this use declines over time. As no significant predictive factors were identified, no specific interventions can be recommended on which the avoidable ED visits depend.

Medicaid Nursing Home Policies and Risk-Adjusted Rates of Emergency Department Visits: Does Rural Location Matter?

ObjectivesMedicaid nursing home (NH) reimbursement rates and bed-hold policies have been shown to be associated with hospitalization of urban NH residents, but their relationships with emergency department (ED) visits, especially in rural NHs, remain unknown. This study explores the relationships of Medicaid NH policies with three NH quarterly risk-adjusted rates of ED use for long-stay residents and evaluates whether the associations differed by NHs' geographical locations. DesignLongitudinal study of Medicaid policies and NH risk-adjusted rates over 3 quarters (2011 Q3, 2012 Q3, and 2013 Q3), using Generalized Estimating Equation (GEE) models. Setting and Participants14,514 unique NHs. MeasuresQuarterly risk-adjusted rates of any ED visit, ED visits without hospitalization or observation stay (outpatient ED), and potentially avoidable ED visits (PAED) were calculated from national Medicare claims and NH Minimum Data Set 3.0. Medicaid policies were consolidated from several publicly available sources. NH and market characteristics were extracted from the Certification And Survey Provider Enhanced Reporting and the Area Health Resources File. ResultsIn 2012, states reimbursed NHs, on average, $162.60 per resident-day, and 36 states employed bed-hold policies. Although a $10 increase in reimbursement rates was associated with statistically significantly lower rates of any ED, outpatient ED, and PAED in both urban and micropolitan NHs (−0.79%, −1.09%, and −1.02% for urban NHs; −1.29%, −1.90%, and −3.22% for micropolitan NHs, respectively), it was not associated with any ED measure in rural NHs. Medicaid bed-hold polices were associated with about 9% to 12% lower rates of all types of ED visits in urban NHs, but were not related to any of the ED measures in micropolitan and rural NHs. Conclusions and ImplicationsAssociations of Medicaid NH policies with ED utilization are weaker in rural NHs than urban NHs. Yet, the financial viability of increasing Medicaid reimbursement to reduce the ED use may not be cost-effective.
