This study aims to theoretically integrate quality factors of both medical and hospitality services in medical tourism. Medical tourism comprises both medicine and tourism. Although the core product in medical tourism is medical treatment, attractive hospitality and travel options are also essential. Despite the dual nature of medical tourism, the two aspects of this concept have not been integrated in a unique framework. This study attempts to fill this gap using interpretive structural modeling (ISM). According to ISM, although factors of medical services and hospitality services are independent from each other, these factors have vital impacts on perceived value, satisfaction, and loyalty. 相似文献

Healthcare reforms have long been advocated as a cure to the increasing healthcare expenditures in advanced economies. Nevertheless, it has not been established whether a market solution via private financing, rather than public financing, curb aggregate healthcare expenditures. To our knowledge, this paper is the first that quantifies the impact of reforms that significantly increases (decreases) the private (public) share of healthcare financing on total healthcare expenditures relative to income in 20 OECD countries. Our reform measure is based on structural break testing of the private share of total expenditures, and verification using evidence of policy reforms. To quantify the effect of these reforms we apply Propensity Score Matching and Inverse Probability Weighted regression analysis. Over a 5-year evaluation period the reforms lead to an accumulated cost saving 0.45 percentage points of GDP. The yearly effects of the reforms are largest in the first years in the post-reform period and decreases in size as a function of time since the reform. Our findings suggest that the investigated healthcare reforms have a relatively short-lived effect on aggregate health spending relative to GDP. The findings are robust to various sensitivity tests. 相似文献

Background: It is estimated that one in 10 people in the US have a diagnosis of diabetes. Type 2 diabetes accounts for 95% of all cases in the US, with annual costs estimated to be $246 billion per year. This study investigated the impact of a glucose-measuring intervention to the burden of type 2 diabetes.Objective: This analysis seeks to understand how professional continuous glucose monitoring (professional CGM) impacts clinical and economic outcomes when compared to patients who are not prescribed professional CGM.Methods: This study utilized a large healthcare claims and lab dataset from the US, and identified a cohort of patients who were prescribed professional CGM as identified by CPT codes 95250 and 95251. It calculated economic and clinical outcomes 1 year before and 1 year after the use of professional CGM, using a generalized linear model.Results: Patients who utilized professional CGM saw an improvement in hemoglobin A1C. The “difference-in-difference” calculation for A1C was shown to be –0.44%. There was no statistically significant difference in growth of total annual costs for people who used professional CGM compared to those who did not ($1,270, p?=?.08). Patients using professional CGM more than once per year had a –$3,376 difference in the growth of total costs (p?=?.05). Patients who used professional CGM while changing their diabetes treatment regimen also had a difference of –$3,327 in growth of total costs (p?=?.0023).Conclusion: Significant clinical benefits were observed for patients who used professional CGM. Economic benefits were observed for patients who utilized professional CGM more than once within a 1-year period or who used it during a change of diabetes therapy. This suggests that professional CGM may help decrease rising trends in healthcare costs for people with type 2 diabetes, while also improving clinical outcomes. 相似文献

Aims: To analyze the association between provider, healthcare costs, and glycemic control for patients with diabetes mellitus (DM).Materials and methods: This cross-sectional study identified adults with type 1 or 2?DM (T1D, T2D) in the Optum database. The main independent variable was provider (endocrinologist or primary care). Regression analysis compared total medical and pharmacy costs, adjusting for health status and other patient differences, by provider.Results: For all patients, HbA1C improvement was greater, and medical costs significantly lower with an endocrinologist rather than a primary care provider. The largest HbA1C improvement (4%) occurred for insulin-dependent patients seen by endocrinologists. Significant medical savings with endocrinologist management occurred within the Medicare Advantage population in every sub-group of patients, with 14% lower costs ($4,767) for patients with T1D, 11% lower costs ($3,160) for patients with macro- and microvascular complications, and 10% lower costs ($2,237) for insulin-dependent patients. Within the commercial insurance population, medical costs were reduced by ≥9% in every sub-group of patients, with a 20% reduction ($8,450) for patients with micro- and macrovascular complications. Overall total costs (medical and pharmacy) were 8% ($1,541) higher for patients receiving endocrinologist rather than primary care, although endocrinologist care resulted in a 9% reduction (–$3,710) in costs for Medicare Advantage patients with T1D. Total medical costs (excluding pharmacy costs) may be a more accurate indicator of costs associated with patients in various stages of DM.Limitations: There was insufficient data to develop risk-adjustment payments for pharmacy costs based on disease severity. The cross-sectional design identifies associations and not cause–effect relationships.Conclusion: DM management by an endocrinologist was associated with greater HbA1C improvement and significantly lower medical costs. Total costs were higher with an endocrinologist, but for patients with T1D lower costs were seen, ranging from 2–9% regardless of insurance type. 相似文献

This study aimed to identify the roles of laypeople at road traffic injuries (RTIs). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of ‘laypeople’, ‘layman’, ‘layperson’, ‘bystander’, ‘first responder’, ‘lay first responder’, ‘road traffic’, ‘road traffic injury’, ‘crash injury’, ‘crash scene’, ‘emergency’, ‘trauma care’, and ‘prehospital trauma care’ were used in combination with the Boolean operators OR and AND. We did electronic search on Google Scholar, PubMed, ISI Web of Science, CINAHL, Science Direct, Scopus, ProQuest. Based on the reviewed studies, some factors such as cultural conditions, knowledge, relief agencies, and demographic factors affect the interventions of laypeople at the crash scene in functional areas. Regarding the permanent presence of people at the crash scene, the present study can provide an opportunity to reduce different side effects of RTIs imposed on the society. 相似文献

The South Korean government's Classification of the Functions of Government (COFOG) is grounded in the System of National Accounts (SNA), rather than Government Finance Statistics (GFS). This article explains why a GFS-based classification might be beneficial to South Korea for the purposes of fiscal management and the comparison of government expenditures with other countries. 相似文献

This paper examines the impact of parties and divided government on infrastructure expenditures for transportation, education, and social services in U.S. states. As infrastructure expenditures are considered a bi-partisan priority, we hypothesize that divided governments expand infrastructure spending compared to governments under true Democratic or Republican control. We test this hypothesis using U.S. state-level data over the period 1970 to 2008 and find that divided governments indeed increase expenditures for these budget categories. Specifically, divided governments spend more on transportation than unified Democratic governments, and more on education and social services than unified Republican governments. The effect is most pronounced for the core infrastructure of transportation and even stronger when only looking at capital outlays instead of total expenditures. 相似文献

We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods. 相似文献
