Provider-to-provider telehealth for sepsis patients in a cohort of rural emergency departments.

BACKGROUND: Telehealth has been proposed as one strategy to improve the quality of time-sensitive sepsis care in rural emergency departments (EDs). The purpose of this study was to measure the association between telehealth-supplemented ED (tele-ED) care, health care costs, and clinical outcomes among patients with sepsis in rural EDs. METHODS: Cohort study using Medicare fee-for-service claims data for beneficiaries treated for sepsis in rural EDs between February 1, 2017, and September 30, 2019. Our primary hospital-level analysis used multivariable generalized estimating equations to measure the association between treatment in a tele-ED-capable hospital and 30-day total costs of care. In our supporting secondary analysis, we conducted a propensity-matched analysis of patients who used tele-ED with matched controls from non-tele-ED-capable hospitals. Our primary outcome was total health care payments among index hospitalized patients between the index ED visit and 30 days after hospital discharge, and our secondary outcomes included hospital mortality, hospital length of stay, 90-day mortality, 28-day hospital-free days, and 30-day inpatient readmissions. RESULTS: In our primary analysis, sepsis patients in tele-ED-capable hospitals had 6.7% higher (95% confidence interval [CI] 2.1%-11.5%) total health care costs compared to those in non-tele-ED-capable hospitals. In our propensity-matched patient-level analysis, total health care costs were 23% higher (95% CI 16.5%-30.4%) in tele-ED cases than matched non-tele-ED controls. Clinical outcomes were similar. CONCLUSIONS: Tele-ED capability in a mature rural tele-ED network was not associated with decreased health care costs or improved clinical outcomes. Future work is needed to reduce rural-urban sepsis care disparities and formalize systems of regionalized care.

Assessing the Acceptability of Less Invasive Caries Removal Techniques for treating Deep Carious Lesions: A Conjoint Survey among Dentists Practicing in a Midwestern American State.

This study identified factors that influence dentists' decisions regarding less invasive caries removal techniques such as stepwise removal (SW) and selective removal (SE) using a marketing research technique, conjoint analysis. A survey was sent to 1,434 dentists practicing in Iowa. Dentists were randomly assigned to receive a questionnaire to rate the likelihood they would use either SW/SE in hypothetical clinical scenarios. The scenarios were carefully created by conjoint design and included three relevant attributes: depth of lesion, hardness of carious dentin, and patient age. Descriptive and conjoint analyses were performed to assess trade-offs between these attributes, using SPSS. The study revealed that depth of lesion was the most important factor in the dentists' decisions (49 importance value) when choosing a SW to treat a deep carious lesion, followed by hardness of carious dentin and patient age (21 importance value). For the SE group, depth of the lesion was also the predominant factor when selecting a treatment. The study also identified that a high proportion of dentists (24.9%) indicated they would never consider using SW or SE under any circumstances. Our survey showed that depth of lesion was the most important reason to select a less invasive caries removal method. The high proportion of dentists indicating they would never consider selective caries removal (SE) techniques suggests that these less invasive options are underutilized.

Comparison of Telehealth and In-Person Behavioral Health Services and Payment in a Large Rural Multisite Usual Care Study.

Background: Telehealth and in-person behavioral health services have previously shown equal effectiveness, but cost studies have largely been limited to travel savings for telehealth cohorts. The purpose of this analysis was to compare telehealth and in-person cohorts, who received behavioral health services in a large multisite study of usual care treatment approaches to examine relative value units (RVUs) and payment. Methods: We used current procedural terminology codes for each encounter to identify RVUs and Medicare payment rates. Mixed linear regression models compared telehealth and in-person cohorts on RVUs, per-encounter payment rates, and total-episode payment rates. Results: We found the behavioral health services provided by telehealth to have modest, but statistically significantly lower RVUs (i.e., less provider work in time spent and case complexity), per-encounter payments, and total episode payments than the in-person cohort. Despite Medicare rates discounting payments for nonphysician providers and the in-person cohort using clinical social workers more frequently, the services provided by the telehealth cohort still had lower payments. Thus, the differences observed are due to the in-person cohort receiving higher payment RVU services than the telehealth cohort, which was more likely to receive briefer therapy sessions and other less expensive services. Conclusions: Behavioral health services provided by telehealth used services with lower RVUs than behavioral health services provided in-person, on average, even after adjusting for patient demographics and diagnosis. Observed differences in Medicare payments resulted from the provider type and services used by the two cohorts; thus, costs and insurance reimbursements may vary for others.

An economic and health outcome evaluation of telehealth in rural sepsis care: a comparative effectiveness study.

Aim: Sepsis is a top contributor to in-hospital mortality and, healthcare expenditures and telehealth have been shown to improve short-term sepsis care in rural hospitals. This study will evaluate the effect of provider-to-provider video telehealth in rural emergency departments (EDs) on healthcare costs and long-term outcomes for sepsis patients. Materials & methods: We will use Medicare administrative claims to compare total healthcare expenditures, mortality, length-of-stay, readmissions, and category-specific costs between telehealth-subscribing and control hospitals. Results: The results of this work will demonstrate the extent to which telehealth use is associated with total healthcare expenditures for sepsis care. Conclusion: These findings will be important to inform future policy initiatives to improve sepsis care in rural EDs. Clinical Trial Registration: NCT05072145 (ClinicalTrials.gov).

Sepsis is a severe condition that results from infection. In addition to costly care, sepsis is a leading cause of death and disability. When comparing outcomes, those treated for sepsis in lower volume emergency departments fare worse and rural emergency departments often have lower patient volumes. While telehealth has been shown to improve sepsis care, the effect of telehealth on costs and long-term outcomes for patients is unclear. This study will use Medicare claims data to compare outcomes for people with sepsis in rural emergency departments who had video telehealth used with those who did not have video telehealth used, with the goal of measuring how telehealth affects healthcare costs, hospital readmissions and deaths after hospital discharge.

The Effects of ACA Medicaid Expansions on Health After 5 Years.

We examine the Affordable Care Act Medicaid expansion effects on self-rated health status over 5 years. The study uses data from the Behavioral Risk Factor Surveillance System for 2011-2018 and a difference-in-differences design. There is improvement in health status on a 1 to 5 point scale from poor to excellent health among individuals below 100% of the federal poverty line by 0.031, 0.068, 0.031, 0.064, and 0.087 points in 2014, 2015, 2016, 2017, and 2018, respectively. Changes in 2015, 2017, and 2018 are statistically significant (p < .05), and the 2014 change is marginally significant. The difference between 2014 and 2018 effects is statistically significant (p < .05). In most years, we cannot distinguish changes in days not in good physical or mental health from no effect. Overall, there is only minimal evidence for effects intensifying over time, suggesting that health gains thus far have mostly occurred early on due to unmet needs among those previously uninsured.

Economic Evaluation of the Emergency Department After Implementation of an Emergency Psychiatric Assessment, Treatment, and Healing Unit.

OBJECTIVES: We sought to evaluate the impact of an emergency psychiatric assessment, treatment, and healing (EmPATH) unit on emergency department (ED) revenue, psychiatric boarding time, and length of stay (LOS). METHODS: We conducted a before-and-after economic evaluation of a single academic midwestern ED (60,000 annual visits) for all adult (≥18 years) patients before (December 2017-May 2018) and after (December 2018-May 2019) opening an EmPATH unit. These are outpatient hospital-based programs that provide emergent treatment and stabilization for mental health emergencies from ED patients. The Holt-Winters method was used to forecast pre-EmPATH expected ED levels of patients leaving without being seen, leaving against medical advice, eloping, or being transferred using 3 years of ED visits. ED revenues were calculated by finding the difference of pre-EmPATH expected and post-EmPATH observed values and multiplying by the revenue per visit. ED boarding time and LOS were obtained from the hospital's electronic medical record. RESULTS: There were 23,231 and 23,336 ED visits evaluated during the pre- and post-EmPATH unit periods. The ED generated an estimated additional $404,954 in the 6 months and $861,065 annually after the implementation of the EmPATH unit. The median (interquartile range [IQR]) psychiatric boarding time decreased from 212 (119-536) minutes to 152 (86-307) minutes (mean difference = 189 minutes, 95% confidence interval [CI] = 150 to 228 minutes) and median (IQR) LOS decreased from 351 (204-631) minutes to 334 (212-517) minutes (mean difference = 114 minutes, 95% CI = 87 to 143 minutes). CONCLUSION: The EmPATH unit had a positive impact on ED revenue and decreased ED boarding time and LOS for psychiatric patients.

Effects of the Recent Medicaid Expansions on Dental Preventive Services and Treatments.

BACKGROUND: Low-income adults in the United States have historically had poor access to dental services largely due to limited dental coverage. OBJECTIVE: We examined the effects of recent Medicaid income-eligibility expansions under the Affordable Care Act on dental visits separately for preventive care and treatments. RESEARCH DESIGN: We used restricted data from the 2011 to 2016 Medical Expenditure Panel Survey with state geocodes. The main analytical sample included nearly 21,000 individuals who were newly eligible for Medicaid. We employed a quasi-experimental difference-in-differences design to identify the impact of the state Medicaid expansions effective in 2014 on dental services use by the level of state Medicaid dental benefit for the newly eligible. RESULTS: Expanding Medicaid in 2014 with extensive or limited dental coverage increased preventive dental visits and use of major dental treatments by over 5 percentage-points in 2014 and 2015. The increase in preventive visits continued in 2016 in expanding states with extensive coverage, while increase in major dental treatments continued in 2016 in expanding states with limited coverage. There is some but less consistent evidence of an increase in dental treatment with emergency-only coverage. CONCLUSIONS: Medicaid expansions with dental coverage beyond emergency-only services have increased access of the newly eligible low-income adults to dental treatments and preventive services, with extensive coverage showing continuing increase in preventive services use 3 years after the expansion. With limited coverage, there is some evidence of individuals needing to stretch treatments over a longer period. Providing comprehensive dental coverage can address unmet dental needs and improve oral health among low-income adults.

Were Patient Protection and Affordable Care Act spillover gains to private dental coverage for dependents widely shared?: An analysis using Medical Expenditure Panel Survey data.

BACKGROUND: The dependent coverage mandate policy of the Patient Protection and Affordable Care Act led to spillover increases in private dental coverage among affected young adults. The authors investigate whether such gains were widely shared across racial or ethnic groups and shared across income levels. The authors further explore the relationship between dental coverage and dental services use stratified by race or ethnicity and income using the mandate as a natural experiment. METHODS: Using nationally representative Medical Expenditure Panel Survey data from 2006 through 2015, the authors used a difference-in-difference regression approach comparing changes in private dental coverage and dental services use for 19- through 25-year-olds affected by the policy with those for unaffected 27- through 30-year-olds. The authors stratified the model by race or ethnicity and income to understand potential differences in the effects of the mandate across these groups. RESULTS: The authors found significant increases in private dental coverage across all racial or ethnic groups as well as across higher- and lower-income young adults. However, despite notable increases in private dental coverage, the authors found little evidence of any overall effects on dental services use. The authors did find evidence suggesting an increased relative likelihood of dental visits for 19- through 25-year-old non-Hispanic blacks compared with slightly older non-Hispanic blacks. CONCLUSIONS: The spillover effect of the dependent coverage mandate on private dental coverage was widely shared across racial or ethnic groups and across income levels. PRACTICAL IMPLICATIONS: Among young adults aged 19 through 25 years, increases in private dental coverage may not be enough on its own to increase the use of preventive dental services and ultimately lead to improved oral health.

The Impact of the ACA Medicaid Expansions on Dental Visits by Dental Coverage Generosity and Dentist Supply.

BACKGROUND: Low-income adults in the United States have historically had limited access to dental coverage and poor dental health outcomes. OBJECTIVE: We examined the effects of the Affordable Care Act Medicaid expansions on dental visits among low-income adults focusing on the generosity of dental coverage and heterogeneity in effects by dentist supply. RESEARCH DESIGN: We used data from 2012, 2014, and 2016 Behavioral Risk Factor Surveillance System surveys. The main analytical sample included nearly 117,000 individuals <138% federal poverty level. We employed a quasi-experimental difference-in-differences design to identify the impact of the state Medicaid expansions on having a dental visit in the past 12 months by the generosity of dental coverage and dentist supply. RESULTS: Medicaid expansions were associated with a nearly 6 percentage-point increase in the likelihood of any dental visits in 2016 (over 10% increase from preexpansion rate) for individuals in Medicaid expanding states with extensive dental benefits. This increase, however, was concentrated in states with high dentist supply with no evidence of improvement in utilization in states with limited dental coverage or low dentist supply. CONCLUSIONS: Expanding Medicaid with generous dental coverage improved dental care use only in areas with high dentist supply with no evidence of benefits with low dentist supply or less generous coverage. Improving access to dental care may require both generous coverage and supply-side interventions to increase dentist availability.

The Effect of Radiofrequency Technology on Time Spent Searching for Surgical Sponges and Associated Costs.

Retained surgical items (eg, sponges, instruments) remain the most frequently reported sentinel events. The primary strategy for preventing retained sponges is the sponge count. Reconciling sponge counts is time consuming and can extend the duration of operative and other invasive procedures. The primary objective of this observational study was to evaluate the effect of a radiofrequency (RF) surgical-sponge detection system on time spent searching for surgical sponges. The study included 27,637 procedures during nine months before and after implementing an RF surgical-sponge detection system. After implementation of the system, time spent searching for sponges was reduced by 79.58%, the percentage of unreconciled counts was reduced by 71.28%, and time spent using radiography to rule out a retained sponge was reduced by 46.31%. This resulted in a reduction of costs. These findings should be used as part of a comprehensive cost analysis of alternative methods when evaluating RF sponge detection technology.

Safety of Back-Transfer to Local Hospitals During an Acute Care Hospitalization.

PURPOSE: This paper investigates patient outcomes including length of stay (LOS), cost of hospitalization, bounce-back rates, transition to hospice care, and mortality, following back-transfer. METHODS: This study was an observational case-control study of adults hospitalized in Iowa between 2005 and 2013 to identify back-transferred patients. Back-transfer was defined as the transfer of rural patients near the end of their acute hospitalization in a comprehensive medical center back to a local community hospital for the completion of their medical care. Demographic, geographic, rurality, procedural, and disease information was compared between case and control groups, then propensity score (PS) matching was performed to create comparable groups to perform analyses. FINDINGS: Over the 9-year period, 1,056,773 patients meeting inclusion criteria were admitted, of which 430 (0.04%) were back-transferred. After PS matching, LOS was 60% (95% CI: 0.50-0.71) higher and costs were 42% (95% CI: 0.33-0.50) higher in the back-transferred group. Back-transferred cases had 8.34 (95% CI: 3.66-19.0) times the odds of hospice transition and 2.17 (95% CI: 1.37-3.46) the odds of mortality compared to controls. Four percent of back-transfers "failed" with the patient being returned to the larger hospital before discharge. CONCLUSIONS: Back-transfer is a rare occurrence, and it is associated with longer LOS, higher hospitalization cost, higher mortality, more hospice transfers, and occasional bounce-backs to comprehensive medical centers. Future work should focus more on prospective indications for transfer, the role of end-of-life care, financial impact, and identifying patient populations for whom back-transfer is safest.

Using tele-emergency to avoid patient transfers in rural emergency departments: An assessment of costs and benefits.

Introduction Tele-emergency can address several challenges facing emergency departments in rural areas. The purpose of this paper is to (a) examine the rates of avoided transfers in rural emergency departments that adopted tele-emergency applications; and (b) estimate the costs and benefits of using tele-emergency to avoid transfers. Methods Analysis is based on 9048 tele-emergency encounters generated by the Avera eEmergency programme (Sioux Falls, South Dakota) in 85 rural hospitals across seven states between October 2009-February 2014. For each non-transfer patient, physicians indicated whether the transfer was avoided because of tele-emergency activation. The cost-benefit analysis is conducted from the hospital, patient and societal perspectives, and includes technology costs, local hospital revenues and patient-associated savings. All monetary values are expressed in US$. Sensitivity analysis is conducted by examining the worst and best case scenarios of costs, revenues and savings. Results In these analyses, 1175 avoided transfers were attributed to tele-emergency. From a rural hospital perspective, tele-emergency costs around US$1739 to avoid a single transfer. However, tele-emergency saves around US$5563 in avoided transportation and indirect patient costs. Combining these, from a societal perspective, tele-emergency has the potential to result in a net savings of US$3823 per avoided transfer while accounting for tele-emergency technology costs, hospital revenues, and patient-associated savings. Conclusion This study highlights various stakeholder perspectives on the financial impact of tele-emergency in avoiding patient transfers in rural emergency departments. Telemedicine has the potential to reduce the number of transfers of emergency department patients and generate some revenue for rural hospitals despite associated technology costs, while incurring substantial patient savings.

Telemedicine Use Decreases Rural Emergency Department Length of Stay for Transferred North Dakota Trauma Patients.

BACKGROUND: Telemedicine has been proposed as one strategy to improve local trauma care and decrease disparities between rural and urban trauma outcomes. OBJECTIVES: This study was conducted to describe the effect of telemedicine on management and clinical outcomes for trauma patients in North Dakota. METHODS: Cohort study of adult (age ≥18 years) trauma patients treated in North Dakota Critical Access Hospital (CAH) Emergency Departments (EDs) from 2008 to 2014. Records were linked to a telemedicine network's call records, indicating whether telemedicine was available and/or used at the institution at the time of the care. Multivariable generalized estimating equations were developed to identify associations between telemedicine consultation and availability and outcomes such as transfer, timeliness of care, trauma imaging, and mortality. RESULTS: Of the 7,500 North Dakota trauma patients seen in CAH, telemedicine was consulted for 11% of patients in telemedicine-capable EDs and 4% of total trauma patients. Telemedicine utilization was independently associated with decreased initial ED length of stay (LOS) (30 min, 95% confidence interval [CI] 14-45 min) for transferred patients. Telemedicine availability was associated with an increase in the probability of interhospital transfer (adjusted odds ratio [aOR] 1.2, 95% CI 1.1-1.4). Telemedicine availability was associated with increased total ED LOS (15 min, 95% CI 10-21 min), and computed tomography scans (aOR 1.6, 95% CI 1.3-1.9). CONCLUSIONS: ED-based telemedicine consultation is requested for the most severely injured rural trauma patients. Telemedicine consultation was associated with more rapid interhospital transfer, and telemedicine availability is associated with increased radiography use and transfer. Future work should evaluate how telemedicine could target patients likely to benefit from telemedicine consultation.

Higher Benefit for Greater Need: Understanding Changes in Mental Well-being of Young Adults Following the ACA Dependent Coverage Mandate.

BACKGROUND: Beginning in late 2010, private health insurance plans were required to allow dependents up to age 26 to remain on a parent's plan. Known as the dependent coverage or young adult mandate, this provision increased coverage substantially within the group of 19-25 year-olds affected by the policy change. Subsequent work evaluating whether increased coverage had a positive effect on mental health found mild improvements in self-reported mental health. This work focused exclusively on average effects among young adults in the years after the policy change, leaving open the question of how young adults fared depending on where they reside in terms of the distribution of risk for mental health issues. AIMS OF THE STUDY: We assess the effects of the dependent coverage mandate on young adult mental well-being focusing on the distribution of mental health issues. We seek to understand how potential improvements (or degradations) differ across the entire risk profile. Gains among individuals who are at low risk for severe mental health issues may send a far different signal than gains among those with higher risks. METHODS: Using MEPS data from 2006 through 2013, we use quantile regression within a difference-in-differences design to compare pre/post outcomes across the distribution of risk for young adults ages 23-25 affected by the mandate to 27-29 year-olds not affected by the mandate. Further, we evaluate differences in the effect of the mandate by sex, given well-known disparities in incidence and prevalence of mental illness between men and women. To gauge the effects of the mandate on mental health, we use the Mental Component Score measure within the MEPS, ideal for our quantile regression given the broad range of scores. The key premise in our evaluation is that individuals with higher risks for mental health problems due to biological or socioeconomics factors are more likely to rank at locations of the mental health score distribution indicating worse outcomes. RESULTS: We find significant improvements in self-reported mental health in the 23-25 year-old group following the mandate. However, the gains were not equal across the risk distribution. For individuals at the 0.1 quantile (worse self-reported mental health), the improvement in MCS scores was significant, a 6.1% increase compared to the pre-mandate baseline at that quantile. Effects were smaller but still significant at the median but there was no apparent effect for those that were at higher levels of self-reported mental health. Our results also suggest improvements for women (+9% relative to baseline at the 0.1 quantile, e.g.) but limited evidence of an effect for men. IMPLICATIONS FOR FUTURE RESEARCH: The finding that increased insurance coverage led to improved self-reported mental health foremost for young adults with the highest risk of mental health problems is encouraging. However, the mechanism for this effect is unclear and in need of further study. Whether improvements in the mental health status of the population depend more on increased access to services or derive primarily from improved financial security is an important research area.

Against the current: back-transfer as a mechanism for rural regionalization.

OBJECTIVES: This paper investigates back-transfer: the transfer of patients near the end of their acute hospitalization to a local community hospital for the completion of their medical care. We seek to describe factors contributing to back-transfer, with the goal of elucidating the current use of back-transfer and barriers to its more widespread adoption for rural healthcare regionalization. STUDY DESIGN: Observational unmatched case-control. METHODS: This was a retrospective study of adults hospitalized in Iowa between 2005 and 2013 to identify back-transferred patients. Demographic, geographic, rurality, procedural, and disease information was compared among cases and control groups using univariate analysis and multivariable logistic regression. RESULTS: Over the 9-year period, 172,544 back-transfer eligible patients were admitted to 1 of 5 large Iowa hospitals, of which 287 (0.2%) were back-transferred. Back-transferred patients were more likely than their non-back-transferred counterparts to be older, male, and white; to live in large rural areas; and to have public insurance. As inpatients, they had longer median lengths of stay (15 vs 5 days; P <.001), more medical comorbidities, and were more likely to have a cardiac catheterization procedure than the control group. CONCLUSIONS: Back-transfer is a very rare event. While demographic and medical differences between back-transferred patients and controls may partially explain the infrequency, other systematic barriers must exist to limit back-transfer. These barriers likely include legal, financial, logistical, and patient care concerns. Despite the rarity with which it is employed, back-transfer is a promising strategy that could better utilize health resources, especially in rural America.

The Impact of the Affordable Care Act's Dependent Coverage Mandate on Use of Dental Treatments and Preventive Services.

BACKGROUND: Oral health problems are the leading chronic conditions among children and younger adults. Lack of dental coverage is thought to be an important barrier to care but little empirical evidence exists on the causal effect of private dental coverage on use of dental services. We explore the relationship between dental coverage and dental services utilization with an analysis of a natural experiment of increasing private dental coverage stemming from the Affordable Care Act's (ACA)-dependent coverage mandate. OBJECTIVES: To evaluate whether increased private dental insurance due to the spillover effect of the ACA-dependent coverage health insurance mandate affected utilization of dental services among a group of affected young adults. DATA: 2006-2013 Medical Expenditure Panel Surveys. STUDY DESIGN: We used a difference-in-difference regression approach comparing changes in dental care utilization for 25-year olds affected by the policy to unaffected 27-year olds. We evaluate effects on dental treatments and preventive services RESULTS:: Compared to 27-year olds, 25-year olds were 8 percentage points more likely to have private dental coverage in the 3 years following the mandate. We do not find compelling evidence that young adults increased their use of preventive dental services in response to gaining insurance. We do find a nearly 5 percentage point increase in the likelihood of dental treatments among 25-year olds following the mandate, an effect that appears concentrated among women. CONCLUSIONS: Increases in private dental coverage due to the ACA's-dependent coverage mandate do not appear to be driving significant changes in overall preventive dental services utilization but there is evidence of an increase in restorative care.

Emergency Department Telemedicine Is Used for More Severely Injured Rural Trauma Patients, but Does Not Decrease Transfer: A Cohort Study.

OBJECTIVES: Traumatic injury is a leading cause of death in the United States, and rural populations are at increased risk of injury and death. Rural residents have limited access to trauma care, and telemedicine has been proposed as one strategy to improve the provision of trauma care locally. The objective of this study was to describe patient-level factors associated with telemedicine consultation in North Dakota critical-access hospital (CAH) emergency departments (EDs) and to measure the association between telemedicine consultation and interhospital transfer. METHODS: Observational cohort study of all adult (age ≥ 18 years) trauma patients treated in North Dakota CAH EDs with an active telemedicine subscription between 2008 and 2014. Trauma cases were identified from the North Dakota Trauma Registry, and telemedicine-enabled care was determined using a probabilistic linking algorithm with the call records of the predominant telemedicine network in North Dakota. Multivariable generalized estimating equations were used to identify factors associated with telemedicine consultation and to measure the association between telemedicine consultation and interhospital transfer, adjusting for patient, injury, and hospital factors. RESULTS: Of the 9,281 North Dakota trauma patients seen in CAHs, 2,837 were treated in an ED with an active telemedicine subscription. Telemedicine was consulted for 11% of all trauma patients in telemedicine-capable EDs. Factors associated with telemedicine consultation included higher Injury Severity Score, penetrating injuries, burns, hypotension, tachycardia, and ambulance transport. Adjusting for severity of illness, injury mechanism, and type of injury, telemedicine use was not associated with interhospital transfer (adjusted odds ratio = 1.28, 95% confidence interval = 0.94 to 1.75). CONCLUSION: Emergency department-based telemedicine consultation is requested for the most severely injured rural trauma patients, especially with those with penetrating trauma, burns, and abnormal presenting vital signs. Telemedicine consultation was not independently associated with increased probability of transfer. Future work should evaluate how telemedicine impacts the timeliness of care and specific care interventions.

The Impact of Medicare Part D on Emergency Department Visits.

The Medicare Part D program introduced prescription drug coverage for seniors in 2006. We examine the impact of this program on the use of emergency department (ED) care. Using a difference-in-differences model, we find declines in the number of ED visits for non-emergency care but not for emergency care, suggesting that Part D may have led to better management of health and reduced unnecessary use of EDs.

Rural Patients With Severe Sepsis or Septic Shock Who Bypass Rural Hospitals Have Increased Mortality: An Instrumental Variables Approach.

OBJECTIVE: To identify factors associated with rural sepsis patients' bypassing rural emergency departments to seek emergency care in larger hospitals, and to measure the association between rural hospital bypass and sepsis survival. DESIGN: Observational cohort study. SETTING: Emergency departments of a rural Midwestern state. PATIENTS: All adults treated with severe sepsis or septic shock between 2005 and 2014, using administrative claims data. INTERVENTIONS: Patients bypassing local rural hospitals to seek care in larger hospitals. MEASUREMENTS AND MAIN RESULTS: A total of 13,461 patients were included, and only 5.4% (n = 731) bypassed a rural hospital for their emergency department care. Patients who initially chose a top-decile sepsis volume hospital were younger (64.7 vs 72.7 yr; p < 0.001) and were more likely to have commercial insurance (19.6% vs 10.6%; p < 0.001) than those who were seen initially at a local rural hospital. They were also more likely to have significant medical comorbidities, such as liver failure (9.9% vs 4.2%; p < 0.001), metastatic cancer (5.9% vs 3.2%; p < 0.001), and diabetes with complications (25.2% vs 21.6%; p = 0.024). Using an instrumental variables approach, rural hospital bypass was associated with a 5.6% increase (95% CI, 2.2-8.9%) in mortality. CONCLUSIONS: Most rural patients with sepsis seek care in local emergency departments, but demographic and disease-oriented factors are associated with rural hospital bypass. Rural hospital bypass is independently associated with increased mortality.

The Effects of Distance to Dentists and Dentist Supply on Children's Use of Dental Care.

OBJECTIVE: To examine the effects of distance to dentists and dentist supply on dental services use among children with Medicaid coverage in Iowa. DATA SOURCE: Iowa Medicaid claims for enrolled children between 2000 and 2009. STUDY DESIGN: The study sample included 41,554 children (providing 158,942 child-year observations) who were born in Iowa between 2000 and 2006 and enrolled from birth in the Iowa Medicaid program. Children were followed through 2009. We used logistic regression to simultaneously examine the effects of distance (miles to nearest dentist) and county-level dentist supply on a broad range of dental services controlling for key confounders. Additional models only used within-child variation over time to remove unobservable time-invariant confounders. PRINCIPAL FINDINGS: Distance was related to lower utilization of comprehensive dental exams (2 percent lower odds per 1 mile increase in distance), an effect that also held in models using within-child variation only. Dentist supply was positively related to comprehensive exams and other preventive services and negatively related to major dental treatments; however, these associations became smaller and insignificant when examining within-child changes except for other preventive services. CONCLUSIONS: Longer distance to dentists is a barrier for use of comprehensive dental exams, conditional on dentist supply.
