Impact of Long-COVID in children: a large cohort study

BackgroundThe impact of long-term Coronavirus disease 2019 (COVID-19) on the pediatric population is still not well understood. This study was designed to estimate the magnitude of COVID-19 long-term morbidity 3–6 months after the date of diagnosis.MethodsA retrospective study of all Clalit Health Services members in Israel aged 1–16 years who tested positive for SARS-CoV-2 between April 1, 2020 and March 31, 2021. Controls, who had no previous diagnosis of COVID-19, were one-to-one matched to 65,548 COVID-19-positive children and teens, and were assigned the infection dates of their matches as their index date. Matching included age, sex, socio-economic score, and societal sector. Individuals were excluded from the study if they had severe medical conditions before the diagnosis such as cancer, diabetes, chronic respiratory diseases, and/or abnormal physiological development. Generalized Estimating Equations were used to estimate the associations between COVID-19 and the use of medical services. The analysis focused on the 3–6 months after the infection date. Adjustments were made for demographics and for the use of medical services 6–12 and 3–6 months before the infection date. The latter was necessary because of observed disparities in medical service utilization between the groups before the COVID-19 diagnosis, despite the matching process.ResultsStatistically significant differences were only found for referrals for mental health services [adjusted relative-risk (RR) 1·51, 95%CI 1·15 − 1·96; adjusted risk-difference (RD) 0·001, 95%CI 0·0006 − 0·002], and medication prescriptions of any kind (RR 1·03, 95%CI 1·01–1·06; RD 0·01 95%CI 0·004 − 0·02).ConclusionsThe significant increase in medication prescriptions and mental health service referrals support the hypothesis that COVID-19 is associated with long-lasting morbidities in children and adolescents aged 1–16 years. However, the risk difference in both instances was small, suggesting a minor impact on medical services.

32 Hypermobile Ehlers-Danlos Syndrome: Phenotypic Presentation, Comorbidity Risk, and Medical Service Utilization in the United States

OBJECTIVES/GOALS: Hypermobile Ehlers-Danlos syndrome (hEDS) is a heritable connective tissue disorder with no known genetic etiology. Its complex phenotypic presentation with multi-system involvement delays proper diagnosis and treatment, especially for females. This study examines the risk for common hEDS comorbidities and medical service utilization. METHODS/STUDY POPULATION: Electronic health records from over 150 million patients across 92 American healthcare servers were queried using the TriNetX database to determine phenotypic presentation of hEDS and risk of receiving comorbid diagnoses. Contingency tables were created with hEDS as the condition and postural orthostatic tachycardia syndrome (POTS) or gastroparesis as the grouping variables. Advanced analytics were conducted to compare outcomes of two cohorts: (1) patients diagnosed with hEDS and both POTS and gastroparesis, and (2) patients with a sole diagnosis of hEDS. After propensity score matching, differences in medical service utilization and mental health diagnoses were assessed between these two cohorts. All analyses restricted age (12-70 years) and employed established exclusion criteria (e.g., diabetes). RESULTS/ANTICIPATED RESULTS: TriNetX national health records (N = 1,968) reveal that hEDS predominantly affects females (87%) and is diagnosed at a mean of 35 years of age. People diagnosed with hEDS have a high prevalence of comorbid nervous system (81%), mental health (76%), and digestive system (69%) disorders. They are 29.7 times more likely to be diagnosed with POTS [95% CI: 27.1, 32.6] and 66.3 times more likely to be diagnosed with gastroparesis [95% CI: 56.5, 77.9], compared to people without hEDS. After propensity score matching for sex, race, and ethnicity, people diagnosed with hEDS and both POTS and gastroparesis have significantly greater service utilization (72.2% vs. 56.7%; z = 2.18, p < .05) but not a greater incidence of mental health disorders (34.4% vs. 24.4%; z = 1.47, p = .14) than people diagnosed with hEDS alone. DISCUSSION/SIGNIFICANCE: This study reveals the phenotypic presentation of hEDS and the elevated risk of co-occurring POTS and/or gastroparesis diagnosis. hEDS and its comorbidities are associated with more frequent medical encounters but not with a greater incidence of mental illness. Findings have implications for both clinical practice guidelines and further research.

Adherence to dietary guidelines associated with lower medical service utilization in preschoolers: a longitudinal study

ObjectiveWe aimed to evaluate the association between dietary guideline adherence and overall, outpatient, and emergency medical service utilization in Taiwanese preschoolers.MethodsWe selected 614 preschoolers (2–6 years) who had one day of 24-h dietary recall data from the 2013–2016 Nutrition and Health Survey in Taiwan. The Taiwanese Children Healthy Eating Index (TCHEI) was developed on the basis of Taiwanese Food-Based Dietary Guidelines; it assesses dietary adequacy and eating behavior. Data on the participants’ outpatient and emergency medical service utilization were obtained for 2013–2018 from the National Health Insurance Research Database. A multivariable generalized linear model was used to evaluate the association between the TCHEI and medical service utilization for all disease and respiratory diseases.ResultsAfter adjustment for confounding factors, children aged 2–3 years in the Tertile (T) 2 and T3 groups of the TCHEI exhibited 25% (95% CI 0.69–0.83) and 16% (95% CI 0.77–0.92) lower overall medical visits, respectively. The same pattern was noted in the outpatient and emergency visits for all diseases and respiratory diseases. The children aged 4–6 years in the T2 group exhibited 15% (95% CI 0.80–0.91) and 11% (95% CI 0.82–0.97) lower overall visits and visits for respiratory diseases, respectively. Moreover, preschoolers in the T2 group exhibited lower overall medical expenditures than did those in the T1 group.ConclusionsTCHEI score was positively correlated with better nutritional status. Optimal dietary intake associated with lower medical service utilization among Taiwan preschoolers.

Measures of patient acuity among children encountered by emergency medical services by the Child Opportunity Index

ABSTRACT Background. Children have differing utilization of emergency medical services (EMS) by socioeconomic status. We evaluated differences in prehospital care among children by the Child Opportunity Index (COI), the agreement between a child’s COI at the scene and at home, and in-hospital outcomes for children by COI. Methods. We performed a retrospective study of pediatric (<18 years) scene encounters from approximately 2,000 United States EMS agencies from the 2021-2022 ESO Data Collaborative. We evaluated socioeconomic status using the multi-dimensional COI v2.0 at the scene. We described EMS interventions and in-hospital outcomes by COI categories using ordinal regression. We evaluated the agreement between the home and scene COI. Results. Data were available for 99.8% of pediatric scene runs, with 936,940 included EMS responses. Children from lower COI areas more frequently had a response occurring at home (62.9% in Very Low COI areas; 47.1% in Very High COI areas). Children from higher COI areas were more frequently not transported to the hospital (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.86-0.87). Children in lower COI areas had lower use of physical (OR 1.23, 95% CI 1.13-1.33) and chemical (OR 1.41, 95% CI 1.29-1.55) restraints for behavioral health problems. Among injured children with elevated pain scores (≥7), analgesia was provided more frequently to children in higher COI areas (OR 1.73, 95% CI 1.65-1.81). The proportion of children in cardiac arrest was lowest from higher COI areas. Among 107,114 encounters with in-hospital data, the proportion hospitalized was higher among children from higher COI areas (OR 1.14, 95% CI 1.11-1.18) and the proportion with in-hospital mortality lower (OR 0.75, 95% CI 0.65-0.85). Home and scene COI had strong agreement (Kendall’s W = 0.81). Conclusion. Patterns of EMS utilization among children with prehospital emergencies differ by COI. Some measures, such as for in-hospital mortality, occurred more frequently among children transported from Very Low COI areas, whereas others, such as admission, occurred more frequently among children from Very High COI areas. These findings have implications in EMS planning and in alternative out-of-hospital care models, including in regional placement of ambulance stations.

Online health information seeking behavior, healthcare access, and health status during exceptional times

Online health information seeking behavior (e-HISB) is becoming increasingly common and the trend has accelerated as a result of the COVID-19 pandemic when individuals strongly relied upon the Internet to stay informed by becoming exposed to a wider array of health information. Despite e-HISB having become a global trend, very few empirical investigations have analyzed its potential influence on healthcare access and individuals’ health status. In this paper, we try to fill this gap. We use data from the second SHARE Corona Survey, supplemented with data from the previous 8th wave of SHARE, and estimate a recursive model of e-HISB, healthcare access, and individuals’ health status that accounts for individuals’ unobserved heterogeneity. Our findings suggest that e-HISB can empower individuals to better understand health concerns, facilitating improved health condition management. However, e-HISB can also trigger a chain reaction, as navigating vast amonts of online health information can heighten fear and anxiety. This increased anxiety may lead to higher utilization of medical services, adversely affecting individuals' perceptions of their health.

Pediatric Utilization of Emergency Medical Services from Outpatient Offices and Urgent Care Centers

ObjectiveNational efforts have highlighted the need for pediatric emergency readiness across all settings where children receive care. Outpatient offices and urgent care centers are frequent starting points for acutely injured and ill children, emphasizing the need to maintain pediatric readiness in these settings. We aimed to characterize emergency medical services (EMS) utilization from outpatient offices and urgent care centers to better understand pediatric readiness needs. MethodsWe performed a retrospective cross-sectional analysis of EMS encounters using the National Emergency Medical Services Information System, a nationally representative EMS registry (2019–2022). We included four years of EMS encounters of children (<18 years old) that originated from an outpatient office or urgent care center. We described characteristics, including patient demographics, prehospital clinician impression, therapies, and procedures performed. ResultsOf 179,854,336 EMS encounters during the study period, 164,387 pediatric encounters originated at an outpatient setting. Most EMS encounters originated from outpatient offices. Evening and weekend EMS encounters more frequently originated from urgent care centers. The most common impressions were respiratory distress (n = 60,716), systemic illness (n = 23,583), and psychiatric/behavioral health (n = 13,273). Ninety-four percent of EMS encounters resulted in transportation to a hospital. ConclusionsEMS encounters from outpatient settings most commonly originate from outpatient offices, relative to urgent care settings, where pediatric emergency readiness may be limited. It is important that outpatient settings and providers are ready for varied emergencies, including those occurring for a behavioral health concern, and that readiness guidelines are updated to address these needs.

Incidence, prevalence, and pattern of medical service utilization of children's rare lung diseases in South Korea.

Children's rare lung diseases are a heterogeneous group of rare lung diseases with significant morbidity and mortality. There is very limited information on the incidence and prevalence of children's rare lung diseases in Asia. We investigated the nationwide incidence, prevalence, and pattern of medical service utilization of children's rare lung diseases in Korea. We studied patients who were diagnosed with rare lung diseases coded per International Statistical Classification of Diseases and Related Health Problems, 10th Edition and registered in the national rare diseases database of confirmed patients. Data was extracted from the Korean National Health Insurance Service Claims database over 2019-2021. Average incidence rate was 12.9 new cases per million children per year, and average prevalence rate was 60.2 cases per million children during the study period of 2019-2021. We found that more than 65% of new cases were diagnosed before 2 years of age. ChILD, primary ciliary dyskinesia, and cystic fibrosis were usually diagnosed after 6 years of age. Congenital airway and lung anomalies were often diagnosed before 2 years of age. Busan and Gyeongsangnam-do residents tended to visit hospitals near their place of residence, while residents of other areas tended to visit hospitals in Seoul regardless of their area of residence. We examined the epidemiology of rare lung diseases in children in South Korea. Our estimation of the incidence and prevalence could be used for sustainable health care and equitable distribution of health care resources.

The impact of the COVID-19 pandemic on treatment for domestic violence injuries: evidence from medical claims

AbstractPrevious studies have observed heterogeneous changes in domestic violence-related 911 calls, police incident reports, and arrests at the onset of the COVID-19 pandemic. In this study, we use a large-scale medical claims database with coverage of over 100 million patients to examine the impact on domestic violence victims’ use of emergency department care for their injuries in the early weeks of the pandemic compared to the corresponding weeks in previous years. We find a 23–35% decrease in utilization of emergency medical services by domestic violence victims between March and June of 2020. Based on this finding, it is essential to use caution when using medical claims to measure domestic violence in future research covering this time period. Decreases in care utilization also have important implications for the detection, screening, and treatment of domestic violence injuries during future public health crises.

The impact of basic health insurance participation characteristics on the health of mobile populations: the mediating role of health service utilization behavior.

It is a pivotal element of China's health system reform to improve the health security of health insurance for the mobile population. Achieving this objective is integral to the success of the reform. The aim of this study was to analyze the impact of different enrollment characteristics of basic health insurance on the health of the mobile population and to investigate the mediating role of health service utilization behavior. This cross-sectional study included 135,372 migrants who participated in the 2018 China Migrants Dynamic Survey (CMDS). Two indicators were employed in this study to assess the characteristics of the mobile population's involvement in basic health insurance-namely, whether or not they participated in local health insurance and the type of health insurance in which they participated. The health status of the mobile population was measured using self-assessed health. Health service utilization behavior was divided into public health service utilization and medical service utilization. Multivariate ordered logistic regression was employed to examine the effect of health insurance on the health of the mobile population. Subsequently, the Bootstrap method was applied to analyze the mediating effect of health service utilization behavior in the relationship between health insurance and the health of the mobile population. Health insurance had a positive impact on health, public health services, and health service utilization among the mobile population. However, enrollment in local health insurance (OR = 1.088, 95% CI = 1.043-1.134) and enrollment in Basic Medical Insurance for Urban Employees (OR = 1.178, 95% CI = 1.090-1.273) were more likely to be associated with higher levels of health and a greater likelihood of receiving health service utilization. The results of the mediating mechanism analysis indicated that health education, health records, family doctor contracting, receiving inpatient services, and being hospitalized locally all played a partially mediating role in the impact of the place of enrollment on health. Regarding the effect of the type of enrollment on health, three types of services-namely, health education, health records, and contracting with a family doctor-played a partially mediating role, while receiving inpatient services and being hospitalized locally did not exhibit a mediating effect. The effect of the type of participation on health is partially mediated. Based on the impact of the different enrolment characteristics of basic health insurance on the health of the mobile population and the mediating role of health service utilization in this impact, furthermore, improvement of health insurance coverage for the mobile population should focus on improving the accessibility of health services, increasing the level of health insurance coverage, mitigating differences in treatment between the different insurance systems, and simplifying the process of transferring the health insurance relationships.

Abstract NS9: Nurse-Led Quality Improvement Initiative: Advancing Stroke Awareness in Communities Experiencing Racial and Ethnic Disparities

Background and Purpose: As a Joint Commission Comprehensive Stroke Center, the provision of community education is a priority goal of our program. The majority of our existing community education program takes place in locations where we receive requests to provide these sessions. Analysis of our Get With the Guidelines (GWTG) data reveals gaps in early arrival to the hospital and Emergency Medical Service (EMS) utilization among African American and Hispanic populations. Providing educational resources within these populations may help to close these gaps and foster trust in the healthcare system. The aim of this proposed nurse-led quality improvement project is to improve hospital arrival times of African American and Hispanic stroke patients living in zip codes where GWTG data have identified gaps, through provision of targeted community education. Methods: The top zip codes associated with our target outcomes for improvement will be identified using GWTG pre-data from 2022 and 2023. We will partner with our Community Outreach department. We will identify educational venues and stakeholders among African American and Hispanic populations in these zip codes. We will provide education tailored to our identified populations including early recognition of stroke signs and symptoms, activation of EMS, stroke risk factors, and opportunities for treatment. Post implementation, GWTG data will be reviewed for any changes. Results: Using GWTG data, arrival mode, last known well time, and symptom discovery time to Emergency Department arrival as it pertains to zip codes, race and ethnicity will be reviewed and analyzed. The target zip codes’ data will be compared pre- versus post-implementation of community education efforts. Discussion: Through community education and partnership with the Community Outreach department we hope to improve timeliness of arrival to hospital among disproportionately affected racial minorities in our community for early stroke evaluation and treatment consideration.

Impact of the Coronavirus Disease 2019 Pandemic on Utilization of Emergency Medical Services in New York City.

Background: This study evaluates trends in the utilization of emergency medical services (EMS) in New York City, the "epicenter" of the first "wave" of the coronavirus pandemic. We hypothesize that EMS call volumes decreased overall in New York City during the first year of the pandemic, specifically with respect to trauma/injury calls. Contrarily, we posit that calls for "sick" events increased given pervasive fear of virus transmission. Materials and Methods: Retrospective New York City EMS calls data (January 1, 2019 to December 31, 2020) were obtained from the NYC Open Data/EMS Incident Dispatch database. Total EMS calls, trauma/injury calls, and "sick" event calls were collected for New York City and for all five boroughs. Census data for each borough were used to weigh daily EMS calls per 100,000 individuals. Mann-Whitney U tests were used to compare pre-pandemic (2019 to March 2020) versus pandemic (April 2020 to December 2020) EMS call volumes, p = 0.05. Results: Median daily EMS calls per 100,000 individuals decreased 21.6% at the start of the pandemic across New York City (pre-pandemic, 3,262 calls; pandemic, 2,556 calls; p < 0.001) and similarly decreased when stratified by borough (all, p < 0.001). Median daily trauma/injury and sick event calls per 100,000 also decreased in New York City and the five boroughs from pre-pandemic to pandemic time periods (all, p < 0.001). Discussion and Conclusions: These data reflect an unprecedented window into EMS utilization during an infectious disease pandemic. As decreased EMS utilization for multiple conditions likely reflects delayed or impeded access to care, utilization data have important implications for provision of acute care services during possible future disruptions related to the pandemic.

Determinants of use of rehabilitation services before entering disability pension: Time series analysis of insured members of the German Pension Insurance Federation in Berlin and Brandenburg

The age-standardized application rate for medical rehabilitation services of the German Pension Insurance Association has been declining since 2009. Two of the most frequent reasons for applying for rehabilitation services represent musculoskeletal disorders and mental disorders. The aim of this analysis was to identify factors influencing the utilization of rehabilitation services in the federal states of Berlin and Brandenburg. The explorative time series analysis is based on a research dataset of the German Pension Insurance Federation. Insured persons of the German Pension Insurance Federation from the federal states of Berlin and Brandenburg with a diagnosis of musculoskeletal disorders or mental disorders were included. Descriptive differences in targeted and prognostic parameters were calculated using chi-square and t-test statistics. Predictive parameters for the utilization of medical rehabilitation services were calculated using binary, logistic regression analyses. A total of 11,257 insured cases were examined. For the population of insured persons from Berlin, the use of medical rehabilitation services showed significant prognostic variables for gender, age at retirement, marital status, level of education, occupational requirement level, total accumulated earning points, gross pension level, status of a temporary pension, health insurance status, and diagnosis group. For Brandenburg, significant prognostic variables were found for age at retirement, marital status, nationality, education level, occupational requirement level, total accumulated earning points, status of a temporary pension, occupational sector, and diagnosis group. In Berlin and Brandenburg mental disorders and sociodemographic parameters are associated with an increased probability of not claiming medical rehabilitation services before the onset of reduced earning capacity. It remains to be investigated which mechanisms cause people with mental disorders to make no use of medical rehabilitation services. Future analyses should examine isolated interaction mechanisms for the utilization of medical rehabilitation services, especially in the case of existing F-diagnoses. In addition, explanations for different influencing variables between states remain to be explored.

Utilization of Medical Services and Self-assessed Health Status among Foreign Residents in Japan

Utilization of Medical Services and Self-assessed Health Status among Foreign Residents in Japan

Uso dos serviços de saúde por pessoas idosas em áreas rurais e urbanas do Brasil

Abstract Objective To assess health services utilization by older adults in urban and rural areas of Brazil. Method A cross-sectional study was conducted analyzing data from the 2019 National Health Survey on older adults (≥60 years) selected from households based on 22,728 interviews (3,300 in rural and 19,426 in urban areas). For rural and urban areas, the prevalence of Family Health Strategy enrolment, time since last medical and dental visit, service use in past 2 weeks, and last blood pressure and blood glucose measurements were estimated. Also, the factors associated with medical and dental health services utilization in the past 12 months were explored. Results Self-rated health of “Very good” or “Good” was greater in urban areas (47.32%), as was the proportion of older adults reporting a medical or dental visit within the last 12 months (90.54%). Rates of blood pressure (81.30%) and glucose (45.83%) monitoring were lower in rural areas. Older individuals that had low education, resided in rural areas, and the North region, had a lower likelihood of using health services Conclusion The older population living in rural areas had poorer health status compared with the urban population.

The Effect of "Offline-to-Online" Trust Transfer on the Utilization of Online Medical Consultation Among Chinese Rural Residents: Experimental Study.

Online medical consultation can serve as a valuable means for rural residents to access high-quality health care resources, thereby mitigating the geographic and economic disadvantages prevalent in rural areas. Nevertheless, due to lower cognitive abilities, rural residents often face challenges in trusting and making effective use of online medical consultations. More likely, adopting a bounded rational decision-making model that facilitates the "offline-to-online" trust transfer could prove to be a potentially effective approach. This strategy aims to encourage less technologically experienced rural residents to trust and make use of online medical consultations. This study aims to characterize the status of "offline-to-online" trust transfer among rural residents in the context of internet health care, and analyze its direct impact on facilitating the utilization of online medical consultation. Additionally, we investigate the family spillover effect of "offline-to-online" trust transfer in promoting the use of online medical consultation among rural family members, considering its distributional effect across various education levels of the population. A multistage stratified random sampling method was used to survey participants in rural areas of China from July to September 2021, encompassing a total of 2597 rural residents from 960 rural households. Propensity score values were estimated using logit regression, and the propensity score matching method, using the K-nearest neighbor matching, radius matching, and kernel matching methods, was applied to create matched treatment and control samples of rural residents based on their experience of "offline-to-online" trust transfer. Subsequently, we calculated average treatment effect scores to compare the differences in utilizing online medical consultation between the treatment and control rural samples. As many as 551/960 (57.4%) rural residents experienced an "offline-to-online" trust transfer, with a higher likelihood observed in the older population with lower levels of education and higher satisfaction with local health care services. Furthermore, rural residents who underwent "offline-to-online" trust transfer were 37%-40% more likely to utilize online medical consultation compared with those who did not experience this trust transfer. Additionally, family members of householders who underwent "offline-to-online" trust transfer were 25%-28% more likely to utilize online medical consultation than those whose householders did not experience this trust transfer. Notably, when compared with populations with high-level education, the "offline-to-online" trust transfer had more significant direct and spillover effects on the utilization of online medical consultation services among rural residents with low-level education. To enhance the "offline-to-online" trust transfer among rural residents and its facilitation in their utilization of online medical consultation, as well as other mobile health (mHealth) and ubiquitous health (uHealth) services, we recommend that online health care providers adopt a "patient-oriented" service model. This approach aims to elevate rural residents' satisfaction with local health care services and harness the trust-building functions inherent in physician-patient relationships and among family members.

Perception, attitudes and expectations among people toward emergency medical services system in Samut Songkhram Province, Thailand

The emergency medical service system is a pre-hospital medical service that effectively helps reduce the severity of emergencies and mortality rates before transferring patients to the hospital. This cross-sectional study investigated people's perceptions, attitudes, and expectations toward the emergency medical services system and aimed to find the relationship between the perceptions, attitudes, and expectations toward the emergency medical services system in Samut Songkhram province, Thailand. The samples consisted of 491 individuals who were selected using a multi-stage sampling method. Data were collected through a self-administered questionnaire and analyzed using linear regression analysis to identify correlations. Results revealed that most participants demonstrated a good overall perception of the use of the emergency medical service system (M = 2.46, SD = 0.27), a good attitude towards the emergency medical service system (M = 2.40, SD = 0.23), and a high level of expectation towards the emergency medical service system (M = 2.85, SD = 0.25). Perception of the use of emergency medical services and attitude towards the emergency medical service system showed positive correlation with expectation towards the emergency medical service system, with R2 = 0.23 (p-value &lt; 0.05). These findings can be used to plan and develop strategies for improving the utilization of emergency medical services, ensuring that the public is informed, understands, and accesses the emergency medical service system correctly and effectively.

Medical service utilization patterns among adults with insomnia: A retrospective cohort study

IntroductionPatients with insomnia can use Korean medicine (KM) alongside conventional medicine (CM) as treatment options within the Korean healthcare system, but the treatment patterns for insomnia remain unclear. This study evaluated the incidence of newly diagnosed insomnia and medical service utilization, including untreated, CM, KM, and concurrent use of CM and KM, and the determinants of treatment after the insomnia diagnosis. MethodsThis retrospective cohort study analyzed adult Korean patients newly diagnosed with insomnia between 2016 and 2018 using National Health Insurance Service data. The cohort who met the eligibility criteria for insomnia was followed up until 2019 to identify their medical service utilization and the determinants. The medical service utilization was defined based on outpatient visits or hospitalization records with insomnia as the primary diagnosis. Descriptive statistics and logistic regression analysis were used to identify the medical service utilization and its determinants. ResultsAmong the 336,578 patients newly diagnosed with insomnia in 2016–2018, only 155,538 (46.21 %) received more than two insomnia treatments during the follow-up period. Of these, 104,751 (67.35 %), 41,762 (26.85 %), and 9,025 (5.80 %) patients received CM monotherapy, KM alone, and both CM and KM, respectively. The statistically significant factors for receiving insomnia treatment after diagnosis were female, age ≥30 years, Seoul capital area residents, lowest income quintile, National Health Insurance Service (NHIS) enrollment types excluding the employee type, and longer elapsed time after diagnosis. The factors for receiving KM alone rather than CM alone were female, aged 40–79 years, residents of the Seoul capital area and metropolitan city, higher income, employee type among the NHIS enrollment types, and a more recent diagnosis. The common factor for concurrent use rather than CM alone was aged 40–79 years, and concurrent use rather than KM alone was being male. ConclusionsMore than half of the patients with insomnia received treatment only once. The utilization of CM or KM alone was higher than that of their combined use. Healthcare professionals can utilize these findings to manage patients with insomnia effectively.

Association of Geographic Distance and Hospital Characteristics With Use of Interhospital Transfer by Air: A Multicenter Retrospective Study

ObjectiveInterhospital transfer by air (IHTA) represents the majority of helicopter air ambulance transports in the United States, but the evaluation of what factors are associated with utilization has been limited. We aimed to assess the association of geographic distance and hospital characteristics (including patient volume) with the use of IHTA. MethodsThis was a multicenter, retrospective study of helicopter flight request data from 2018 provided by a convenience sample of 4 critical care transport medicine programs in 3 US census regions. Nonfederal referring hospitals located in the home state of the associated critical care transport medicine program and within 100 miles of the primary receiving facility in the region were included if complete data were available. We fit a Poisson principal component regression model incorporating geographic distance, the number of emergency department visits, the number of hospital discharges, case mix index, the number of intensive care unit beds, and the number of general beds and tested the association of the variables with helicopter emergency medical services utilization. ResultsA total of 106 referring hospitals were analyzed, 21 of which were hospitals identified as having a consistent request pattern. Using the hospitals with a consistent referral pattern, geographic distance had a significant positive association with flight request volume. Other variables, including emergency department visit volume, were not associated. Overall, the included variables offered poor explanatory power for the observed variation between referring facilities in the use of IHTA (r2 = 0.09). Predicted flights based on the principal component regression model for all referring hospitals suggested the majority of referring hospitals used multiple flight programs. ConclusionGeographic distance is associated with the use of IHTA. Unexpectedly, most basic hospital characteristics are not associated with the use of IHTA, and the degree of variation between referring facilities that is explained by patient volume is limited. The evaluation of nonhospital factors, such as the density and availability of critical care or advanced life support ground emergency medical services resources, is needed.

Effects of private health insurance on healthcare services during the MERS Pandemic: Evidence from Korea

This study investigates how private health insurance impacted healthcare services during the MERS pandemic in Korea. Using the Korea Health Panel Study (KHPS), this study examines the difference in healthcare utilization between insured and uninsured individuals during the pandemic. If insured individuals use fewer healthcare services than the uninsured during the MERS pandemic, it could be evidence of moral hazard. During the MERS outbreak, the probability of outpatient medical services utilization was lower by 19 % than during non-pandemic periods. All individuals decreased the number of outpatient visits by 7 %. Insured individuals reduced outpatient visits more than the uninsured in response to the MERS pandemic. The increased outpatient utilization by private health insurance could be attributed to both moral hazard and adverse selection. However, given that people with poor health cannot enroll in private health insurance due to the insurance company's screening process, moral hazard leads to increase healthcare utilization rather than adverse selection.

Medicare Advantage Is Associated with Lower Utilization of Total Joint Arthroplasty.

Medicare Advantage (MA) insurers use managed care techniques to review the utilization of medical services and control costs. It is unclear if MA enrollees have a lower utilization of elective surgical procedures such as inpatient hip and knee total joint arthroplasty (TJA), which have traditionally been covered by traditional Medicare (TM) without restrictions. We conducted a cross-sectional study using a 20% sample of 2018 TM claims and MA encounter records for 5,300,188 TM enrollees and 1,970,032 MA enrollees who were 65 to 85 years of age. We calculated unadjusted and adjusted differences (controlling for beneficiary and market characteristics) in the incidence of TJA for MA compared with TM, and by MA plan type. Finally, we calculated differences in the time to contact with an orthopaedic surgeon and time to the surgical procedure among enrollees with an osteoarthritis diagnosis. After controlling for observable characteristics, there was a 15.6% lower incidence of TJA in MA enrollees compared with TM enrollees (p < 0.001). Compared with TM enrollees, health maintenance organization (HMO) enrollees were 28.1% less likely to undergo TJA, controlling for observable characteristics (p < 0.001).
