Analyzing Cost-Effectiveness of Allocating Neurointerventionist for Drive and Retrieve System for Patients with Acute Ischemic Stroke.

OBJECTIVES: There are regional disparities in implementation rates of endovascular thrombectomy due to time and resource constraints such as endovascular thrombectomy specialists. In Hokkaido, Japan, Drive and Retrieve System (DRS), where endovascular thrombectomy specialists perform early endovascular thrombectomies by traveling from the facilities where they normally work to facilities closer to the patient. This study analyzed the cost-effectiveness of allocating a endovascular thrombectomy specialist for DRS to treat stroke patients. MATERIALS AND METHODS: he number of ischemic stroke patients expected to receive endovascular thrombectomy in Hokkaido in 2015 was estimated. It was assumed that an additional neutointerventionist was allocated for DRS. The analysis was performed from the government's perspective, which includes medical and nursing-care costs, and the personnel cost for endovascular thrombectomy specialist. The analysis was conducted comparing the current scenario, where patients received endovascular thrombectomy in facilities where endovascular thrombectomy specialists normally work, with the scenario with DRS within 60 min drive distance. Patient transport time was analyzed using geographic information system, and patient severity was estimated from the transport time. The primary outcome was incremental cost-effectiveness ratio (ICER) in each medical area which was calculated from the incremental costs and the incremental quality-adjusted life years (QALYs), estimated from patient severity using published literature. The entire process was repeated 100 times. RESULTS: DRS was most cost-effective in Kamikawachubu area, where the ICER was $14,173±16,802/QALY, significantly lower than the threshold that the Japanese guideline suggested. CONCLUSIONS: Since DRS was cost-effective in Kamikawachubu area, the area should be prioritized when a endovascular thrombectomy specialist for DRS is allocated as a policy.

Geographic Variation in Breast Reconstruction Modality Use Among Women Undergoing Mastectomy.

PURPOSE: Despite changes in legislation and an increase in public awareness, many women may not have access to the various types of breast reconstruction. The purpose of this study was to evaluate variation in reconstructive modality at the health service area (HSA) level and its relationship to the plastic surgeon workforce in the same area. METHODS: Using the Arkansas, California, Florida, Nebraska, and New York state inpatient databases, we conducted a cross-sectional study of adult women undergoing mastectomy for cancer from 2009 to 2012. The primary outcomes were receipt of reconstruction and the reconstructive modality (autologous tissue versus implant) used. All data were aggregated to the HSA level and augmented with plastic surgeon workforce data. Correlation coefficients were calculated for the relationship between the outcomes and workforce. RESULTS: The final sample included 67,984 women treated across 103 HSAs. The average patient was 58.5 years, had private insurance (53.5%), and underwent unilateral mastectomy for invasive cancer. At the HSA level, the median immediate breast reconstruction rate was 25.0% and varied widely (interquartile range, 43.2%). In areas where reconstruction was performed, the median autologous (10.2%) and free tissue (0.4%) reconstruction rates were low, with more than 30% of HSAs never using autologous tissue. There was a direct correlation between an HSA's plastic surgeon density and autologous reconstruction rate (r = 0.81, P < 0.001). CONCLUSIONS: Despite efforts to remove financial barriers and improve patients' awareness, accessibility to various modalities of reconstruction is inadequate for many women. Efforts are needed to improve the availability of more comprehensive breast reconstruction care.

Market Consolidation and Mortality in Patients Initiating Hemodialysis.

BACKGROUND: It is uncertain whether consolidation in health care markets affects the quality of care provided and health outcomes. OBJECTIVES: To examine whether changes in market competition resulting from acquisitions by two large national for-profit dialysis chains were associated with patient mortality. METHODS: We identified patients initiating in-center hemodialysis between 2001 and 2009 from a registry of patients with end-stage renal disease in the United States. We considered two scenarios when evaluating consolidation from dialysis facility acquisitions: one in which we considered only those patients receiving dialysis in markets that became substantially more concentrated to have been affected by consolidation, and the other in which all patients living in hospital service areas where a facility was acquired were potentially affected. We used a difference-in-differences study design to examine the associations between market consolidation and changes in mortality rates. RESULTS: When we considered the 12,065 patients living in areas that became substantially more consolidated to have been affected by consolidation, we found a nominally significant (8%; 95% confidence interval 0%-17%) increase in likelihood of death after consolidation. Nevertheless, when we considered all 186,158 patients living in areas where an acquisition occurred to have been affected by consolidation, there was no observable effect of market consolidation on mortality. CONCLUSIONS: Decreased market competition may have led to increased mortality among a relatively small subset of patients initiating in-center hemodialysis in areas that became substantially more concentrated after two large dialysis acquisitions, but not for most of the patients living in affected areas.

Cross-border spatial accessibility of health care in the North-East Department of Haiti.

BACKGROUND: The geographical accessibility of health services is an important issue especially in developing countries and even more for those sharing a border as for Haiti and the Dominican Republic. During the last 2 decades, numerous studies have explored the potential spatial access to health services within a whole country or metropolitan area. However, the impacts of the border on the access to health resources between two countries have been less explored. The aim of this paper is to measure the impact of the border on the accessibility to health services for Haitian people living close to the Haitian-Dominican border. METHODS: To do this, the widely employed enhanced two-step floating catchment area (E2SFCA) method is applied. Four scenarios simulate different levels of openness of the border. Statistical analysis are conducted to assess the differences and variation in the E2SFCA results. A linear regression model is also used to predict the accessibility to health care services according to the mentioned scenarios. RESULTS: The results show that the health professional-to-population accessibility ratio is higher for the Haitian side when the border is open than when it is closed, suggesting an important border impact on Haitians' access to health care resources. On the other hand, when the border is closed, the potential accessibility for health services is higher for the Dominicans. CONCLUSION: The openness of the border has a great impact on the spatial accessibility to health care for the population living next to the border and those living nearby a road network in good conditions. Those findings therefore point to the need for effective and efficient trans-border cooperation between health authorities and health facilities. Future research is necessary to explore the determinants of cross-border health care and offers an insight on the spatial revealed access which could lead to a better understanding of the patients' behavior.

Predicting declines in perceived relationship continuity using practice deprivation scores: a longitudinal study in primary care.

BACKGROUND: Increased relationship continuity in primary care is associated with better health outcomes, greater patient satisfaction, and fewer hospital admissions. Greater socioeconomic deprivation is associated with lower levels of continuity, as well as poorer health outcomes. AIM: To investigate whether deprivation scores predicted variations in the decline over time of patient-perceived relationship continuity of care, after adjustment for practice organisational and population factors. DESIGN AND SETTING: An observational study in 6243 primary care practices with more than one GP, in England, using a longitudinal multilevel linear model, 2012-2017 inclusive. METHOD: Patient-perceived relationship continuity was calculated using two questions from the GP Patient Survey. The effect of deprivation on the linear slope of continuity over time was modelled, adjusting for nine confounding variables (practice population and organisational factors). Clustering of measurements within general practices was adjusted for by using a random intercepts and random slopes model. Descriptive statistics and univariable analyses were also undertaken. RESULTS: Relationship continuity declined by 27.5% between 2012 and 2017, and at all deprivation levels. Deprivation scores from 2012 did not predict variations in the decline of relationship continuity at practice level, after accounting for the effects of organisational and population confounding variables, which themselves did not predict, or weakly predicted with very small effect sizes, the decline of continuity. Cross-sectionally, continuity and deprivation were negatively correlated within each year. CONCLUSION: The decline in relationship continuity of care has been marked and widespread. Measures to maximise continuity will need to be feasible for individual practices with diverse population and organisational characteristics.

Medicare Facility Diagnosis-Related Groups Have Outpaced Individual Physician Payment.

BACKGROUND: We set out to compare the rates of Medicare reimbursement to physicians versus hospitals for several major vascular procedures over a period of 5 years. METHODS: We queried the Wolters Kluwer MediRegs database to collect Medicare reimbursement data from fiscal years 2011 to 2015. We surveyed reimbursements for carotid endarterectomy, carotid angioplasty and stenting, femoropopliteal bypass, and lower extremity fem-pop revascularization with stenting. Based on data availability, we surveyed physician reimbursement data on the national level and in both medically overserved and underserved areas. Hospital reimbursement rates were examined on a national level and by hospitals' teaching and wage index statuses. RESULTS: We found that for all 4 vascular procedures, Medicare reimbursements to hospitals increased by a greater percentage than to physicians. By region, underserved areas had lower physician reimbursements than the national average, while the opposite was true for overserved areas. Additionally, for hospital Medicare reimbursements, location in a high wage index accounted for a significant increase in reimbursement over the national average, with teaching status contributing to this increase in a smaller extent. CONCLUSIONS: These data on Medicare reimbursements indicate that payments to hospitals are increasing more significantly than to physicians. This disparity in pay changes affects both independent and academic vascular surgeons. Medicare should consider pay increases to independent providers in accordance to the hospital pay increase.

The Struggle for Equity: An Examination of Surgical Services at Two NGO Hospitals in Rural Haiti.

BACKGROUND: Health systems must deliver care equitably in order to serve the poor. Both L'Hôpital Albert Schweitzer (HAS) and L'Hôpital Bon Sauveur (HBS) have longstanding commitments to provide equitable surgical care in rural Haiti. HAS charges fees that demonstrate a preference for the rural population near the hospital, with free care available for the poorest. HBS does not charge fees. The two hospitals are otherwise similar in surgical capacity and rural location. METHODS: We retrospectively reviewed operative case-logs at both hospitals from June 1 to Aug 31, 2012. The records were compared by total number of operations, geographic distribution of patients and number of elective operations. Using geography as a proxy for poverty, we analyzed the equity achieved under the financial systems at both hospitals. RESULTS: Patients from the rural service area received 86% of operations at HAS compared to 38% at HBS (p < 0.001). Only 5% of all operations at HAS were performed on patients from outside the service area for elective conditions compared to 47% at HBS (p < 0.001). Within its rural service area, HAS performed fewer operations on patients from the most destitute areas compared to other locations (40.3 vs. 101.3 operations/100,000 population, p < 0.001). CONCLUSIONS: Using fees as part of an equity strategy will likely disadvantage the poorest patients, while providing care without fees may encourage patients to travel from urban areas that contain other hospitals. Health systems striving to serve the poor should continually evaluate and seek to improve equity, even within systems that provide free care.

[Ophthalmology and urban underprivileged. Experience of 150 patients]. / Ophtalmologie et situation de précarité en milieu urbain. À propos d'une expérience de 150 patients.

INTRODUCTION: An ophthalmology consultation was carried out at the Hôtel-Dieu to facilitate eye care in underprivileged patients referred by the general medicine PASS (socialized health care) of the same hospital. MATERIALS AND METHODS: The files of 150 consecutive patients examined by a single ophthalmologist between January 2012 and June 2013 were reviewed. A standard examination was performed in these patients, sent with a consult sheet, to which a response was sent to PASS. As necessary, prescriptions were also written for the patients. RESULTS: Most patients (89/150) were immigrants from sub-Saharan Africa. Additionally, there were 25 Europeans with only 5 French, and 17 Asians. The mean age was 41 years with 90 men (mean age 43) and 60 women (mean age 36). The most common systemic diseases observed were hypertension, (13), diabetes (6), and hepatitis (6). The mean best-corrected visual acuity (129 patients) was a slightly more than 8/10 (16/20) (measurable in 143 patients). Refractive state (measured in 129 patients) was myopia (46), hyperopia (41), presbyopia (isolated in 12 cases), astigmatism (26), and emmetropia (28). Optical correction was prescribed in 87 patients. The main pathological conditions included pingueculae (19), cataracts (19), trauma (13) of which 4 patients were monocular, and pterygia (9). DISCUSSION AND CONCLUSION: Refractive errors were the main abnormality observed in these underprivileged patients. Apart from cataract as a pathologic condition observed in the general population, more characteristic of this sub-Saharan population were pinguecula, pterygium and trauma. This study highlights the more general question of access to eye care for all underprivileged patients.

[Morbidity observed in a health area: Impact on professionals and funding]. / Morbilidad observada en un área sanitaria: variabilidad e impacto en profesionales y en financiación.

OBJECTIVE: To analyze morbidity, in the context of a health area, and broken down by health centre, of patients who made contact with healthcare services, in order to propose an adjustment to finance the payment per capita. DESIGN: A descriptive study of morbidity observed in citizens assigned a health area during year 2010. SITE: Health Area 9. Autonomous Community of Madrid. Formed by the municipalities of Fuenlabrada, Humanes, and Moraleja de Enmedio. All levels of health care included. PARTICIPANTS: All citizens with health card assigned to a health center in the area who has maintained contact with the public health service's own area. MEASUREMENTS: Coded contact of patients are grouped using the Population Grouping Clinical Risk 3M TM Software (CRG). Each patient is included in a homogeneous and exclusive group with a numerical morbidity and clinical sense. Through the health card is known primary care centre, physician, age and sex. RESULTS: The distribution of morbidity is obtained by primary care centre, primary care physician, age and sex analyzing differences and combinations. CONCLUSIONS: It was found that the average values of the population morbidity are different in each primary care centre. In order to maintain the principle of equity in health care, it is suggested that an adjustment is made to the per capita payment based on the morbidity rate of the population.

The financial impact of hospitals on the local economy--2 new factors.

This research effort presents a descriptive analysis of the financial impact that several hospitals have on their local economy. An earlier study published by the authors included 3 distinct, yet overlapping components of financial impact: (1) the hospital system as a major health care provider, (2) the hospital system as a large employer, and (3) the hospital system as an entity whose employees contribute greatly to their local community. This new study added additional financial impact factors: (4) the hospital system as an organization committed to major construction projects in pursuit of its health services mission, and (5) the hospital system as an entity that pays taxes to government agencies. The inextricable relationship of these 5 categories both increases and enhances the impact of the hospital system on the local region. The results of this updated and expanded analysis suggest strongly that the hospital system represents 1 of the primary contributors to the economy of the region. The hospital system adds $3 billion to the $28 billion local economy, which means that the hospital system and its employees are responsible for 10.7% of the total economic prowess of the region.

Association of U.S. Dialysis facility neighborhood characteristics with facility-level kidney transplantation.

BACKGROUND: Improving access to optimal healthcare may depend on the attributes of neighborhoods where patients receive healthcare services. We investigated whether the characteristics of dialysis facility neighborhoods--where most patients with end-stage renal disease are treated--were associated with facility-level kidney transplantation. METHODS: We examined the association between census tract (neighborhood)-level sociodemographic factors and facility-level kidney transplantation rate in 3,983 U.S. dialysis facilities where kidney transplantation rates were high. Number of kidney transplants and total person-years contributed at the facility level in 2007-2010 were obtained from the Dialysis Facility Report and linked to the census tract data on sociodemographic characteristics from the American Community Survey 2006-2010 by dialysis facility location. We used multivariable Poisson models with generalized estimating equations to estimate the link between the neighborhood characteristics and transplant incidence. RESULTS: Dialysis facilities in the United States were located in neighborhoods with substantially greater proportions of black and poor residents, relative to the national average. Most facility neighborhood characteristics were associated with transplant, with incidence rate ratios (95% CI) for standardized increments (in percentage) of neighborhood exposures of: living in poverty, 0.88 (0.84-0.92), black race, 0.83 (0.78-0.89); high school graduates, 1.22 (1.17-1.26); and unemployed, 0.90 (0.85-0.95). CONCLUSION: Dialysis facility neighborhood characteristics may be modestly associated with facility rates of kidney transplantation. The success of dialysis facility interventions to improve access to kidney transplantation may partially depend on reducing neighborhood-level barriers.

[Decentralized outpatient teams in community-based psychiatric care: comparison of two Bavarian rural catchment areas]. / Dezentrale ambulante Teams in der gemeindenahen psychiatrischen Versorgung : Zwei bayerische ländliche Regionen im Vergleich.

BACKGROUND: Psychiatric outpatient clinics (PIAs) are an indispensable care service for crisis intervention and multidisciplinary treatment of people suffering from severe and persistent mental disorders. The decentralization of outpatient clinics can be understood as a further step in the deinstitutionalization process. METHODS: This cross-sectional study (n=1,663) compared the central outpatient clinic with the decentralized teams for the year 2010 by means of analyses of variance, χ(2)-tests and robust multivariate regression models. The longitudinal assessment (descriptively and by means of Prais-Winsten regression models for time series) was based on all hospitalizations for the two decentralized teams (n = 6,693) according to partial catchment areas for the time period 2002-2010 in order to examine trends after their installation in the year 2007. RESULTS: Decentralized teams were found to be similar with respect to the care profile but cared for relatively more patients suffering from dementia, addictive and mood disorders but not for those suffering from schizophrenia and personality disorders. Decentralized teams showed less outpatient care costs as well as psychopharmacological expenses but a lower contact frequency than the central outpatient clinic. Total expenses for psychiatric care were not significantly different and assessed hospitalization variables (e.g. total number of annual admissions, cumulative length of inpatient-stay and annual hospitalizations per patient) changed slightly 3 years after installation of the decentralized teams. The number of admissions of people suffering from schizophrenia decreased whereas those for mood and stress disorders increased. DISCUSSION: Decentralized outpatient teams seemed to reach patients in rural regions who previously were not reached by the central outpatient clinic. Economic figures indicate advantages for the installation of such teams because care expenses are not higher than for patients treated in centralized outpatient clinics and because hospitalization figures for the whole catchment area did not increase.

Accessibility to primary health care in Belgium: an evaluation of policies awarding financial assistance in shortage areas.

BACKGROUND: In many countries, financial assistance is awarded to physicians who settle in an area that is designated as a shortage area to prevent unequal accessibility to primary health care. Today, however, policy makers use fairly simple methods to define health care accessibility, with physician-to-population ratios (PPRs) within predefined administrative boundaries being overwhelmingly favoured. Our purpose is to verify whether these simple methods are accurate enough for adequately designating medical shortage areas and explore how these perform relative to more advanced GIS-based methods. METHODS: Using a geographical information system (GIS), we conduct a nation-wide study of accessibility to primary care physicians in Belgium using four different methods: PPR, distance to closest physician, cumulative opportunity, and floating catchment area (FCA) methods. RESULTS: The official method used by policy makers in Belgium (calculating PPR per physician zone) offers only a crude representation of health care accessibility, especially because large contiguous areas (physician zones) are considered. We found substantial differences in the number and spatial distribution of medical shortage areas when applying different methods. CONCLUSIONS: The assessment of spatial health care accessibility and concomitant policy initiatives are affected by and dependent on the methodology used. The major disadvantage of PPR methods is its aggregated approach, masking subtle local variations. Some simple GIS methods overcome this issue, but have limitations in terms of conceptualisation of physician interaction and distance decay. Conceptually, the enhanced 2-step floating catchment area (E2SFCA) method, an advanced FCA method, was found to be most appropriate for supporting areal health care policies, since this method is able to calculate accessibility at a small scale (e.g., census tracts), takes interaction between physicians into account, and considers distance decay. While at present in health care research methodological differences and modifiable areal unit problems have remained largely overlooked, this manuscript shows that these aspects have a significant influence on the insights obtained. Hence, it is important for policy makers to ascertain to what extent their policy evaluations hold under different scales of analysis and when different methods are used.

The effect of activity-based financing on hospital length of stay for elderly patients suffering from heart diseases in Norway.

BACKGROUND: Whether activity-based financing of hospitals creates incentives to treat more patients and to reduce the length of each hospital stay is an empirical question that needs investigation. This paper examines how the level of the activity-based component in the financing system of Norwegian hospitals influences the average length of hospital stays for elderly patients suffering from ischemic heart diseases. During the study period, the activity-based component changed several times due to political decisions at the national level. METHODS: The repeated cross-section data were extracted from the Norwegian Patient Register in the period from 2000 to 2007, and included patients with angina pectoris, congestive heart failure, and myocardial infarction. Data were analysed with a log-linear regression model at the individual level. RESULTS: The results show a significant, negative association between the level of activity-based financing and length of hospital stays for elderly patients who were suffering from ischemic heart diseases. The effect is small, but an increase of 10 percentage points in the activity-based component reduced the average length of each hospital stay by 1.28%. CONCLUSIONS: In a combined financing system such as the one prevailing in Norway, hospitals appear to respond to economic incentives, but the effect of their responses on inpatient cost is relatively meagre. Our results indicate that hospitals still need to discuss guidelines for reducing hospitalisation costs and for increasing hospital activity in terms of number of patients and efficiency.

The influence of drug use in university hospitals on the pharmaceutical consumption in their surrounding communities.

AIM: To investigate the influence of hospital drug choices on pharmaceutical consumption for nine competitive classes in the surrounding community. METHODS: Ecological study. Data from the national survey on drugs in hospitals were used to extract quantities purchased by 25 French university hospitals for three 'hospital classes' (EPOs, LMWHs and setrons) and six 'ambulatory classes' (PPIs, ACEIs and ARBs, statins, α-adrenoreceptor antagonists (AAAs) and selective serotonin re-uptake inhibitors SSRIs). Re-imbursed quantities for patients living in the hospital's catchment area were extracted from the national health insurance database. The relationship between the use of a brand in hospitals and their catchment areas was assessed using multivariate linear regressions with instrumental variables. RESULTS: An increase of 1 day of treatment with one brand in the hospital was associated with a significant increase of 2.8 days of treatment with the same brand in the catchment area. However, results strongly varied according to classes. An increase of 1 day of treatment in the hospital was significantly associated with an increase of 0.21 day for 'hospital classes' and 21.8 days for 'ambulatory classes' in the catchment area. Strong variations were seen across 'ambulatory classes'. The effect was maximal for cardiovascular classes and not significant for AAAs and SSRIs. The size of the effect also varied with hospital characteristics: small and proximity university hospitals exerted the greatest influence. CONCLUSIONS: Hospital consumption influences the use of drugs in the community. A significant effect was found, especially for competitive classes used on a long-term basis. The economic consequences of these findings need to be addressed.
