The interconnection of medical devices is emerging as a new requirement in modern medicine. The final goal of connecting heterogeneous medical devices in a wider network of computational servers is to monitor and improve patient safety, where it also constitutes a major goal in the Integrated Clinical Environment (ICE) framework. The heterogeneity of medical devices provided by different suppliers is a key challenge in ICE-based systems, where interoperability and data communication across devices is still under study and specification. ICE aims to create a standard interface that covers medical devices heterogeneity, hence, achieving interoperability in a safe way. It focuses on defining an interoperable bus between the patient, medical devices, software applications, and the clinician. Given the lack of realization of ICE standard, this paper presents a component-based framework for making ICE usable for medical applications. This work illustrates the component model in detail and validates it with a prototype implementation that focuses on the integration of heterogeneous medical devices as the most relevant requirements faced by ICE.

Polymeric materials, due to their excellent physicochemical properties and versatility found applicability in multiples areas, including biomaterials used in tissue regeneration, prosthetics (hip, artificial valves), medical devices, controlled drug delivery systems, etc. Medical devices and their applications are very important in modern medicine and the need to develop new materials with improved properties or to improve the existent materials is increasing every day. Numerous reasearches are activated in this domain in order to obtain materials/surfaces that does not have drawbacks such as structural failure, calcifications, infections or thrombosis. One of the most used material is poly(vinylchloride) (PVC) due to its unique properties, availability and low cost. The most common method used for obtaining tubular devices that meet the requirements of medical use is the surface modification of polymers without changing their physical and mechanical properties, in bulk. PVC is a hydrophobic polymer and therefore many research studies were conducted in order to increase the hydrophilicity of the surface by chemical modification in order to improve biocompatibility, to enhance wettability, reduce friction or to make lubricious or antimicrobial coatings. Surface modification of PVC can be achieved by several strategies, in only one step or, in some cases, in two or more steps by applying several techniques consecutively to obtain the desired modification / performances. The most common processes used for modifying the surface of PVC devices are: plasma treatment, corona discharge, chemical grafting, electric discharge, vapour deposition of metals, flame treatment, direct chemical modification (oxidation, hydrolysis, etc.) or even some physical modification of the roughness of the surface.

Background: It is important to discard those practices that do not add value. As a result, several initiatives have emerged. All of them try to improve patient safety and the use of health resources. Purpose: To present a compendium of "do not do recommendations" in the context of hemophilia. Methods: A review of the literature and current clinical guidelines has been made, based on the best evidence available to date. Results: The following 13 recommendations stand out: 1) Do not delay the administration of factor after trauma; 2) do not use fresh frozen plasma or cryoprecipitate; 3) do not use desmopressin in case of hematuria; 4) do not change the product in the first 50 prophylaxis exposures; 5) do not interrupt immunotolerance; 6) do not administer aspirin or NSAIDs; 7) do not administer intramuscular injections; 8) do not do routine radiographs of the joint in case of acute hemarthrosis; 9) Do not apply closed casts for fractures; 10) do not discourage the performance of physical activities; 11) do not deny surgery to a patient with an inhibitor; 12) do not perform instrumental deliveries in fetuses with hemophilia; 13) do not use factor IX (FIX) in patients with hemophilia B with inhibitor and a history of anaphylaxis after administration of FIX. Conclusions: The information mentioned previously can be useful in the management of hemophilia, from different levels of care. As far as we know, this is the first initiative of this type regarding hemophilia.

Bioresorbable cardiovascular applications are increasing in demand as fixed medical devices cause episodes of late restenosis. The autologous treatment is, so far, the gold standard for vascular grafts due to the similarities to the replaced tissue. Thus, the possibility of customizing each application to its end user is ideal for treating pathologies within a dynamic system that receives constant stimuli, such as the cardiovascular system. Direct Ink Writing (DIW) is increasingly utilized for biomedical purposes because it can create composite bioinks by combining polymers and materials from other domains to create DIW-printable materials that provide characteristics of interest, such as anticoagulation, mechanical resistance, or radiopacity. In addition, bioinks can be tailored to encounter the optimal rheological properties for the DIW purpose. This review delves into a novel emerging field of cardiovascular medical applications, where this technology is applied in the tubular 3D printing approach. Cardiovascular stents and vascular grafts manufactured with this new technology are reviewed. The advantages and limitations of blending inks with cells, composite materials, or drugs are highlighted. Furthermore, the printing parameters and the different possibilities of designing these medical applications have been explored.

Background and problemThe WHO Surgical Safety Checklist has been shown to improve patient safety as well as improving teamwork and communication in theatres. In 2009, it was made a mandatory requirement for all NHS hospitals in England and Wales. The WHO checklist is intended to be adapted to suit local settings and was modified for use in Gloucestershire Hospitals NHS Foundation Trust. In 2018, it was decided to review the use of the adapted WHO checklist and determine whether improvements in compliance and engagement could be achieved.AimThe aim was to achieve 90% compliance and engagement with the WHO Surgical Safety Checklist by April 2019.MethodsIn April 2018, a prospective observational audit and online survey took place. The results showed compliance for the ‘Sign In’ section of the checklist was 55% and for the ‘Time Out’ section was 91%. Engagement by the entire theatre team was measured at 58%. It was proposed to move from a paper checklist to a wall-mounted checklist, to review and refine the items in the checklist and to change the timing of ‘Time Out’ to ensure it was done immediately prior to knife-to-skin.ResultsFollowing its introduction in September 2018, the new wall-mounted checklist was reaudited. Compliance improved to 91% for ‘Sign In’ and to 94% for ‘Time Out’. Engagement by the entire theatre team was achieved 100% of the time. Feedback was collected, adjustments made and the new checklist was rolled out in stages across all theatres. A reaudit in December 2018 showed compliance improved further, to 99% with ‘Sign In’ and to 100% with ‘Time Out’. Engagement was maintained at 100%.ConclusionsThe aim of the project was met and exceeded. Since April 2019, the new checklist is being used across all theatres in the Trust.

The paper summarises previous theories of accident causation, human error, foresight, resilience and system migration. Five lessons from these theories are used as the foundation for a new model which describes how patient safety emerges in complex systems like healthcare: the System Evolution Erosion and Enhancement model. It is concluded that to improve patient safety, healthcare organisations need to understand how system evolution both enhances and erodes patient safety.

Pediatrics 2016; 138: e20160069 Kinder auf der Neugeborenen-Intensivstation sind besonders durch Komplikationen während des Krankenhausaufenthaltes gefährdet. Dies gilt auch für die Intubation, die relativ häufig mit unerwünschten Ereignissen einhergeht. US-amerikanische Neonatologen haben jetzt untersucht, durch welche Maßnahmen sich die Komplikationsrate bei Intubationen in ihrem Perinatal- Zentrum senken lässt.
