Pharmaceutical cost control in primary care: opinion and contributions by healthcare professionals
<p>Abstract</p> <p>Background</p> <p>Strategies adopted by health administrations and directed towards drug cost control in primary care (PC) can, according to earlier studies, generate tension between health administrators and healthcare professionals. This study collects and analyzes the opinions of general practitioners (GPs) regarding current cost control measures as well as their proposals for improving the effectiveness of these measures.</p> <p>Methods</p> <p>A qualitative exploratory study was carried out using 11 focus groups composed of GPs from the Spanish regions of Aragon, Catalonia and the Balearic Islands. A semi-structured guide was applied in obtaining the GPs' opinions. The transcripts of the dialogues were analyzed by two investigators who independently considered categorical and thematic content. The results were supervised by other members of the team, with overall responsibility assigned to the team leader.</p> <p>Results</p> <p>GPs are conscious of their public responsibility with respect to pharmaceutical cost, but highlight the need to spread responsibility for cost control among the different actors of the health system. They insist on implementing measures to improve the quality of prescriptions, avoiding mere quantitative evaluations of prescription costs. They also suggest moving towards the self-management of the pharmaceutical budget by each health centre itself, as a means to design personalized incentives to improve their outcomes. These proposals need to be considered by the health administration in order to pre-empt the feelings of injustice, impotence, frustration and lack of motivation that currently exist among GPs as a result of the implemented measures.</p> <p>Conclusion</p> <p>Future investigations should be oriented toward strategies that involve GPs in the planning and management of drug cost control mechanisms. The proposals in this study may be considered by the health administration as a means to move toward the rational use of drugs while avoiding concerns about injustice and feelings of impotence on the part of the GPs, which can lead to lack of interest in and disaffection with the current measures.</p
Design, characterization and installation of the NEXT-100 cathode and electroluminescence regions
NEXT-100 is currently being constructed at the Laboratorio Subterr\'aneo de
Canfranc in the Spanish Pyrenees and will search for neutrinoless double beta
decay using a high-pressure gaseous time projection chamber (TPC) with 100 kg
of xenon. Charge amplification is carried out via electroluminescence (EL)
which is the process of accelerating electrons in a high electric field region
causing secondary scintillation of the medium proportional to the initial
charge. The NEXT-100 EL and cathode regions are made from tensioned hexagonal
meshes of 1 m diameter. This paper describes the design, characterization, and
installation of these parts for NEXT-100. Simulations of the electric field are
performed to model the drift and amplification of ionization electrons produced
in the detector under various EL region alignments and rotations. Measurements
of the electrostatic breakdown voltage in air characterize performance under
high voltage conditions and identify breakdown points. The electrostatic
deflection of the mesh is quantified and fit to a first-principles mechanical
model. Measurements were performed with both a standalone test EL region and
with the NEXT-100 EL region before its installation in the detector. Finally,
we describe the parts as installed in NEXT-100, following their deployment in
Summer 2023.Comment: 35 pages, 25 Figures, update includes accepted version in JINS
A Compact Dication Source for Ba Tagging and Heavy Metal Ion Sensor Development
We present a tunable metal ion beam that delivers controllable ion currents
in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed
by sequential atomic evaporation and single or multiple electron impact
ionization, followed by acceleration into a sensing region. Controllability of
the ionic charge state is achieved through tuning of electrode potentials that
influence the retention time in the ionization region. Barium, lead, and cobalt
samples have been used to test the system, with ion currents identified and
quantified using a quadrupole mass analyzer. Realization of a clean
ion beam within a bench-top system represents an important
technical advance toward the development and characterization of barium tagging
systems for neutrinoless double beta decay searches in xenon gas. This system
also provides a testbed for investigation of novel ion sensing methodologies
for environmental assay applications, with dication beams of Pb and
Cd also demonstrated for this purpose
Ba+2 ion trapping using organic submonolayer for ultra-low background neutrinoless double beta detector
If neutrinos are their own antiparticles the otherwise-forbidden nuclear reaction known as neutrinoless double beta decay can occur. The very long lifetime expected for these exceptional events makes its detection a daunting task. In order to conduct an almost background-free experiment, the NEXT collaboration is investigating novel synthetic molecular sensors that may capture the Ba dication produced in the decay of certain Xe isotopes in a high-pressure gas experiment. The use of such molecular detectors immobilized on surfaces must be explored in the ultra-dry environment of a xenon gas chamber. Here, using a combination of highly sensitive surface science techniques in ultra-high vacuum, we demonstrate the possibility of employing the so-called Fluorescent Bicolor Indicator as the molecular component of the sensor. We unravel the ion capture process for these molecular indicators immobilized on a surface and explain the origin of the emission fluorescence shift associated to the ion trapping
NEXT-CRAB-0: A High Pressure Gaseous Xenon Time Projection Chamber with a Direct VUV Camera Based Readout
The search for neutrinoless double beta decay () remains one
of the most compelling experimental avenues for the discovery in the neutrino
sector. Electroluminescent gas-phase time projection chambers are well suited
to searches due to their intrinsically precise energy
resolution and topological event identification capabilities. Scalability to
ton- and multi-ton masses requires readout of large-area electroluminescent
regions with fine spatial resolution, low radiogenic backgrounds, and a
scalable data acquisition system. This paper presents a detector prototype that
records event topology in an electroluminescent xenon gas TPC via VUV
image-intensified cameras. This enables an extendable readout of large tracking
planes with commercial devices that reside almost entirely outside of the
active medium.Following further development in intermediate scale
demonstrators, this technique may represent a novel and enlargeable method for
topological event imaging in .Comment: 32 Pages, 22 figure
La profesión de salud pública y el debate de las competencias profesionales Public health professionals and professional competences debate
A pesar de sus contribuciones en el pasado, la salud pública ocupa en la actualidad una posición marginal en el sistema sanitario. Este insuficiente protagonismo se asocia con el escaso reconocimiento de la profesión y de sus profesionales. Para fortalecer la salud pública se debe profundizar en la coherencia de sus objetivos y de su base científica y metodológica, así como garantizar la competencia de sus profesionales. La falta de institucionalización de est os elementos limita la articulación de los objetivos de salud pública en una serie de prácticas eficaces. Así pues, no se han desarrollado lo que se denomina «competencias profesionales» específicas de la salud pública: el conjunto de habilidades que deben ser capaces de llevar a cabo los profesionales. El contenido profesional se debe definir a partir del análisis de las funciones y de las actividades específicas necesarias para desarrollarlas. En este trabajo se pretende estimular una reflexión, a la luz de la experiencia de otros países, que permita iniciar una nueva reconstrucción de la salud pública, mediante la cual se pueda abandonar la situación marginal actual y mejorar el desempeño de su función social.Despite its historical contribution to the improvement of health, public health occupies a marginal position in health systems. This lack of correspondence between impact and power is related in part to its scarce recognition as a profession, and in consequence to the lack of recognition of the professionals in the field. The strengthening of the public health profession requires recognising the coherence of their objectives and scientific basis, but it also requires the establishment of mechanisms to guarantee professional competence. Generally, the institutionalisation of these necessary mechanisms to articulate public health objectives into effective professional practice has been lacking. In other words, the so-called professional competencies lacked development in public health. Progress in this strategy calls for the definition of the professional content based on a functional analysis of public health. That is, an analysis of the functions that these professionals must contribute to society and of the specific activities necessary to achieve the desired outcomes. The aim of this work is to stimulate a debate along these lines taking into account the experience
Implementing the WHO Safe Childbirth Checklist: lessons from a global collaboration.
The WHO Safe Childbirth Checklist (SCC) was developed to ensure the delivery of essential maternal and perinatal care practices around the time of childbirth. A research collaboration was subsequently established to explore factors that influence use of the Checklist in a range of settings around the world. This analysis article presents an overview of the WHO SCC Collaboration and the lessons garnered from implementing the Checklist across a diverse range of settings. Project leads from each collaboration site were asked to distribute two surveys. The first was given to end users, and the second to implementation teams to describe their respective experiences using the Checklist. A total of 134 end users and 38 implementation teams responded to the surveys, from 19 countries across all levels of income. End users were willing to adopt the SCC and found it easy to use. Training and the provision of supervision while using the Checklist, alongside leadership engagement and local ownership, were important factors which helped facilitate initial implementation and successful uptake of the Checklist. Teams identified several challenges, but more importantly successfully implemented the WHO SCC. A critical step in all settings was the adaptation of the Checklist to reflect local context and national protocols and standards. These findings were invaluable in developing the final version of the WHO SCC and its associated implementation guide. Our experience will provide useful insights for any institution wishing to implement the Checklist
Two new RHD alleles with deletions spanning multiple exons
Background: The most common large-deletion RHD allele (RHD*01N.01) includes the entire coding sequence, intervening regions and untranslated regions. The rest of large-deletion RHD alleles reported to-date consist of single-exon deletions, such as RHD*01N.67 which includes exon 1. Materials and Methods: Samples from two donors with RhD-negative serology yielded unclear or inconclusive results when subject to confirmatory testing on RHD genotyping arrays. To determine their RHD genotypes, genomic DNA was analyzed with a combination of allele-specific PCR, long-range PCR, Sanger sequencing, and next-generation sequencing assays. Results: Allele-specific PCR failed to detect products for RHD exons 1 to 3 in one sample and RHD exons 1 to 5 in the other. A quantitative next-generation sequencing assay confirmed deletion of exons 1 to 3 and 1 to 5 respectively, and detected the absence of an RHD gene in trans in both samples. Long-range PCR and Sanger sequencing enabled identification of the breakpoints for both alleles. Both deletions start within the 5′ Rhesus box (upstream of the identity region for the 1-to-3 deletion, downstream of it for the 1-to-5 deletion), and end within introns. Conclusions: Resolution of unclear or inconclusive results from targeted genotyping arrays often leads to the discovery of new alleles. The 5′ Rhesus box may be a hot spot for genetic recombination events, such as the large deletions described in this report. © 2020 AAB
