The complement system resembles a double-edged sword since its activation can either benefit or harm the host. Thus, regulation of this system is of utmost importance and performed by several circulating and membrane-bound complement inhibitors. The pool of well-established regulators has recently been enriched with proteins that either share structural homology to known complement inhibitors such
Aims: Pre-capillary pulmonary hypertension (PHpre-cap) has a poor prognosis, especially when caused by pulmonary arterial hypertension (PAH) associated with systemic sclerosis (SSc-PAH). Whether cardiac magnetic resonance (CMR)-based quantification of atrial volumes in PHpre-cap is beneficial in risk assessment is unknown. The aims were to investigate if (i) atrial volumes using CMR are associated
Purpose: The purpose of this paper is to increase the understanding of how warehouse operations and design are affected by the move toward integrated omni-channels. Design/methodology/approach: A structured literature review is conducted to identify and categorize themes in multi- and omni-channel logistics, and to discuss how aspects related to these themes impact and pose contingencies for wareh
This paper presents a comparison of horizontal equity in health care utilization in 10 European countries and the US. It does not only extend previous work by using more recent data from a larger set of countries, but also uses new methods and presents disaggregated results by various types of care. In all countries, the lower-income groups are more intensive users of the health care system. But a
The OECD countries finance their health care through a mixture of taxes, social insurance contributions, private insurance premiums and out-of-pocket payments. The various payment sources have very different implications for both vertical and horizontal equity and on redistributive effect which is a function of both. This paper presents results on the income redistribution consequences of the heal
This paper presents further international comparisons of progressivity of health care financing systems. The paper builds on the work of Wagstaff et al. [Wagstaff, A., van Doorslaer E., et al., 1992. Equity in the finance of health care: some international comparisons, Journal of Health Economics 11, pp. 361-387] but extends it in a number of directions: we modify the methodology used there and ac
This paper has two purposes. The first purpose is methodological and aims to extend previous work on efficiency analysis by implementing a multiple-output stochastic ray frontier production function model. This model generalizes the single-output stochastic frontier model to multiple-input, multiple-output technologies and allows simultaneous estimation of technical efficiency and analysis of infl
This paper tests the null hypothesis of a zero effect of cesarean section rate on health outcome against the alternative of a positive effect. Using data from 59 hospitals in Sweden from 1988-92, we specify two separate linear regression models for health outcome, one with perinatal mortality, and the other with rate of asphyxia, as dependent variable. We estimate the models by single-year cross-s
This paper decomposes the redistributive effect of the personal income taxes (PITs) of twelve OECD countries into four components: (i) an average rate effect, (ii) a departure-from-proportionality or progressivity effect, (iii) a horizontal equity effect and (iv) a reranking effect. The product of (i) and (ii) indicates the vertical redistribution associated with the PIT and the sum of (iii) and (
In this paper we estimate a 'Grossman' model of demand for health based on Swedish micro data. The data set consists of a random sample of over 5000 individuals taken from the Swedish adult population. Health capital is measured by a categorical measure of overall health status, and an ordered probit model is used to econometrically estimate the demand for health equation. The results are consiste
Aims: Pulmonary congestion remains a diagnostic challenge in patients with heart failure (HF). The recommended method, chest X-ray (CXR), lacks in accuracy, whereas quantitative tomographic lung scintigraphy [ventilation/perfusion single-photon emission computed tomography (V/P SPECT)] has shown promising results but needs independent validation. The aim of this study is to evaluate V/P SPECT as a
This paper estimates a "Grossman" model of demand for health. We measure health status on a 0 (dead) to 1 (full health) cardinal scale by the rating scale method and the time trade-off method. We also use a categorical measure of overall health status commonly used in quality of life measurements. To estimate the demand for health equations, the Tobit technique is used for the rating scale and tim
The aim of this note is to validate Wagstaff and van Doorslaer's approach of constructing a continuous health measure to be used in the analysis of inequalities in health. We calculate health concentration indices for Uppsala County in Sweden based on three different health status measures: health measured according to the WvD approach based on a self-assessed categorical health measure, health me
A purchaser/provider split together with output-based reimbursement were recently introduced by several Swedish county councils. These changes have been motivated by arguments of efficiency and consumer choice. This paper tests the null hypothesis that hospital services are provided as efficiently by county councils with internal markets and output-based reimbursement as by county councils with bu
Background: Economic evaluation of new treatments in the field of glaucoma represents a challenge. In the absence of a clear epidemiological link between intra-ocular pressure (IOP) and disease progression to blindness, the economic impact of treatments that lower IOP on long-term outcome cannot be estimated. As an alternative, effectiveness may be expressed as the ability to control IOP over time
This paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: county council taxes, payroll taxes, direct payments and state grants. The redistributive effects are decomposed into vertical, horizontal and 'reranking' segments for each of the four financial sources. The data used are based on probability samples
This paper examines the determinants of hip fracture costs and further evaluates potential savings in costs when the occurrence of hip fracture is prevented. The costs of hip fracture are comprised of direct costs from health care and the social welfare system. Data were collected for 1,080 postmenopausal women admitted from private residence for primary hip fracture surgery during the year of 199
The objective of this study was to explain the variation in cesarean section rates among hospitals (obstetrical departments) in Sweden, and to discuss its potential economic consequences. Using data from The Swedish Medical Birth Registry 1991, we made a cross-sectional study of the cesarean section rate at the departmental level. We identified some 20 determinants, demand-related as well as suppl
Aims: To clarify the frequency and severity of diabetic retinopathy in a group of people with Type 2 diabetes and chronic diabetic foot ulcers, and to compare visual acuity, levels of retinopathy and clinical significant macular oedema with a matched control group of people with Type 2 diabetes without a history of chronic diabetic foot ulcers. Methods: Visual acuity and fundus imaging were evalua
There is mutual agreement that health care should be delivered according to need. In this article, although we employ different specifications for need, we conclude that there is inequity in the delivery of health care in Sweden. Higher income groups visit doctors more often than lower income groups in relation to need, but lower income groups remain in hospital longer once they have been admitted
