Markets and Public Values in Healthcare

Abstract: Discussions on the role of markets in healthcare easily lead to political and unfruitful polarized positions. Actors arguing in favour of markets as a solution for the quality/cost conundrum entrench themselves against others pointing out the risk of markets for the delivery and governance of healthcare. These binary options of more or less marketization preclude a more empirical analysis of how markets, as multiple arrangements, are constructed and what their consequences are for public values like affordability and quality. To empirically explore the relation between markets and public values in healthcare, in this paper we analyze the construction of a market for hospital care in the Netherlands, based on a system of diagnoserelated groups (DBCs), and the development of a market for long term care based on care-load packages (ZZPs). In these cases we address the intended result of care markets according to various policy actors, the visible and invisible work done by various actors to make markets work and the values enacted in market practices. We show that where policy aims within these markets focus on providing choice and increasing diversity of care institutions, the instruments of DBCs and ZZPs rather produce isomorphism and homogenization. Furthermore, the strong influence of financial instruments in shaping healthcare markets assume that cost and quality can both be strengthened while it in fact has a profound influence on how public values like quality get defined in practice. These translations between values pursued and outcomes produced indicate that conceptualizing the role of the state as defining public values that markets (have to) implement is problematic, as this removes crucial normative work in the shaping of our welfare states to the realm of the technical operationalization of markets. An alternative relation between state, market and society can be conceived once we accept that such values are shaped in practice and that the relationship between policy aims and policy consequences can never be fully captured through a logic of implementation. This then calls for an experimental role of the state: a state that sees market developments as experimental devices in which the aim is a good composition of public values. We propose this experimentation could for example focus on market developments that do not ascribe a privileged status to financial devices and price-mechanism, such as a market for the DBC A-segment, in which prices are not freely negotiable.

Optimizing the Timing of Highest Hydrocortisone Dose in Children and Adolescents With 21-Hydroxylase Deficiency

CONTEXT: Hydrocortisone treatment of young patients with 21-hydroxylase deficiency (21OHD) is given thrice daily, but there is debate about the optimal timing of the highest hydrocortisone dose, either mimicking the physiological diurnal rhythm (morning), or optimally suppressing androgen activity (evening). OBJECTIVE: We aimed to compare 2 standard hydrocortisone timing strategies, either highest dosage in the morning or evening, with respect to hormonal status throughout the day, nocturnal blood pressure (BP), and sleep and activity scores. METHODS: This 6-week crossover study included 39 patients (aged 4-19 years) with 21OHD. Patients were treated for 3 weeks with the highest hydrocortisone dose in the morning, followed by 3 weeks with the highest dose in the evening (n = 21), or vice versa (n = 18). Androstenedione (A4) and 17-hydroxyprogesterone (17OHP) levels were quantified in saliva collected at 5 am; 7 am; 3 pm; and 11 pm during the last 2 days of each treatment period. The main outcome measure was comparison of saliva 17OHP and A4 levels between the 2 treatment strategies. RESULTS: Administration of the highest dose in the evening resulted in significantly lower 17OHP levels at 5 am, whereas the highest dose in the morning resulted in significantly lower 17OHP and A4 levels in the afternoon. The 2 treatment dose regimens were comparable with respect to averaged daily hormone levels, nocturnal BP, and activity and sleep scores. CONCLUSION: No clear benefit for either treatment schedule was established. Given the variation in individual responses, we recommend individually optimizing dose distribution and monitoring disease control at multiple time points

Measurement of the neutron electric dipole moment via spin rotation in a non-centrosymmetric crystal

We have measured the neutron electric dipole moment using spin rotation in a non-centrosymmetric crystal. Our result is d_n = (2.5 +- 6.5(stat) +- 5.5(syst)) 10^{-24} e cm. The dominating contribution to the systematic uncertainty is statistical in nature and will reduce with improved statistics. The statistical sensitivity can be increased to 2 10^{-26} e cm in 100 days data taking with an improved setup. We state technical requirements for a systematic uncertainty at the same level.Comment: submitted to Phys. Lett.

GATA transcription factors in testicular adrenal rest tumours

Testicular adrenal rest tumours (TARTs) are benign adrenal-like testicular tumours that frequently occur in male patients with congenital adrenal hyperplasia. Recently, GATA transcription factors have been linked to the development of TARTs in mice. The aim of our study was to determine GATA expression in human TARTs and other steroidogenic tissues. We determined GATA expression in TARTs (n = 16), Leydig cell tumours (LCTs; n = 7), adrenal (foetal (n = 6) + adult (n = 10)) and testis (foetal (n = 13) + adult (n = 8)). We found testis-like GATA4, and adrenal-like GATA3 and GATA6 gene expressions by qPCR in human TARTs, indicating mixed testicular and adrenal characteristics of TARTs. Currently, no marker is available to discriminate TARTs from LCTs, leading to misdiagnosis and incorrect treatment. GATA3 and GATA6 mRNAs exhibited excellent discriminative power (area under the curve of 0.908 and 0.816, respectively), while immunohistochemistry did not. GATA genes contain several CREB-binding sites and incubation with 0.1 mM dibutyryl cAMP for 4 h stimulated GATA3, GATA4 and GATA6 expressions in a human foetal testis cell line (hs181.tes). Incubation of adrenocortical cells (H295RA) with ACTH, however, did not induce GATA expression in vitro Although ACTH did not dysregulate GATA expression in the only human ACTH-sensitive in vitro model available, our results do suggest that aberrant expression of GATA transcription factors in human TARTs might be involved in TART formation

Birth weight in different etiologies of disorders of sex development

Context: It is well established that boys are heavier than girls at birth. Although the cause of birth weight (BW) difference is unknown, it has been proposed that it could be generated from prenatal androgen action. Objective: The aim of the current study was to determine the BW of children with disorders of sex development (DSD) of different etiologies and to evaluate the effects of androgen action on BW. Methods: Data regarding diagnosis, BW, gestational age, karyotype, and concomitant conditions were collected from the InternationalDisorders of SexDevelopment (I-DSD) Registry (www.i-dsd).BWstandard deviation score was calculated according to gestational age. Cases were evaluated according to disorder classification in I-DSD (i.e., disorders of gonadal development, androgen excess, androgen synthesis, androgen action, nonspecific disorder of undermasculinization groups, and Leydig cell defect). Results: A total of 533 cases were available; 400 (75%) cases were 46,XY, and 133 (25%) cases were 46,XX. Eighty cases (15%) were born small for gestational age (SGA). Frequency of SGA was higher in the 46,XY group (17.8%) than in the 46,XX (6.7%) group (P = 0.001). Mean BW standard deviation scores of cases with androgen excess and androgen deficiency [in disorders of gonadal development, androgen synthesis, and Leydig cell defect groups and androgen receptor gene (AR)mutation-positive cases in disorders of androgen action groups]were similar to normal childrenwith the same karyotype. SGA birth frequency was higher in the AR mutation-negative cases in disorders of androgen action group and in the nonspecific disorders of the undermasculinization group. Conclusions: BWdimorphism is unlikely to be explained by fetal androgen action per se. 46,XY DSDs due to nonspecific disorders of undermasculinizationare more frequently associatedwithfetal growth restriction, SGA, and concomitant conditions

Bronnen van antibioticaresistentie in het milieu en mogelijke maatregelen

Het RIVM heeft in samenwerking met andere instituten onderzocht hoeveel resistente bacteriën via afvalwater in het Nederlandse oppervlaktewater terechtkomen. Afvalwater is, naast mest, de belangrijkste bron waardoor antibioticaresistente bacteriën in het milieu belanden. In 60 tot 100% van het onderzochte afvalwater zitten bijzonder resistente micro-organismen(BMRO), zoals ESBL-producerende E. coli en carbapenemresistente Enterobacteriaceae. Daarnaast zijn resten van antibiotica in het afvalwater gevonden. Mensen kunnen aan resistente bacteriën in het milieu worden blootgesteld, bijvoorbeeld als zij in contact komen met water waarop gezuiverd afvalwater wordt geloosd. Vooralsnog is het onduidelijk hoe groot de bijdrage van deze blootstelling is ten opzichte van andere blootstellingsroutes, en wat de gevolgen daarvan voor de volksgezondheid zijn. Daarvoor wordt aanvullend onderzoek aanbevolen. Duidelijk is wel dat mensen naast blootstelling via het milieu, ook door andere bronnen kunnen worden blootgesteld aan antibioticaresistente bacteriën, bijvoorbeeld tijdens reizen naar landen in Azië of Zuid-Amerika. Door de huidige behandeling van afvalwater nemen de concentraties van antibioticaresistente bacteriën af. Er bestaan aanvullende zuiveringstechnieken voor afvalwater die het aantal antibioticaresistente bacteriën in het oppervlaktewater nog verder kunnen verminderen. Ook de concentraties van resistente bacteriën in mest kunnen door aanvullende zuiveringstechnieken verminderd worden.In collaboration with other institu tions , RIVM investigated how many resistant bacteria enter Dutch surface water s from waste water treatment plants. Next to manure, waste water is the main source of resistant bacteria in the environment. Resistant bacteria of particular public health concern, including ESBL -producing E. coli and carbapenem resistant Enterobacteriace ae, have been found in 60 -100% of all investigated waste water samples. Antibiotics themselves have also been found in waste water. Human exposure to resistant bacteria is possible, for example, upon contact with surface water which receives waste water treatment plant effluent. So far, the contribution of this exposure to the total exposure to resistant bacteria is unknown, as are the effects of this exposure on public health. Additional research is therefore recommended. Humans can also be exposed to resistant bacteria via other routes, such as travel to Asian or Latin American. The current treatment of waste water reduces the concen trations of resistant bacteria. Advanced techniques are available which can decrease the amounts of resistant bacteria further. Options for the reduction of resistant bacteria also exist for the treatment of manure
