Computer start zeer langzaam op. Het langzaam opstarten van uw computer kan verschillende oorzaken hebben, van virusinfectie en conflicterende opstartitems tot meerdere beveiligingsproducten van derden. Norton kan uitkomst bieden voor enkele van de oorzaken en de opstarttijd van uw computer reduceren.

Ik heb onlangs windows 10 geïnstalleerd op mijn laptop. Sinds korte tijd heb ik problemen met het opstarten van windows. Het duurt soms wel 5 minuten terwijl ik er een ssd in heb zitten. Met we vorige windows duurde dit niet langer dan enkele seconden.

Op met het opstarten van sommige programma's of games moet ik soms wel 10 minuten wachten.

Kan iemand mij adviseren waar dit aan ligt en hoe ik dit kan oplossen zonder dat ik weer terug moet naar een oudere windows versie?

Dit zijn mijn specs:

The Veterans Information Systems and Technology Architecture (VISTA) is the nationwide veterans clinical and business information system of the U.S. Department of Veterans Affairs. VISTA consists of 180 applications for clinical, financial, and administrative functions all integrated within a single database, providing single, authoritative source of data for all veteran-related care and services. The U.S. Congress mandates the VA keep the veterans health record in a single, authoritative, lifelong database, which is VISTA.

VISTA supports the clinical, administrative, and financial operations of over 1200 hospitals and clinics of the Veterans Health Administration (VHA).^[1] The VHA is the largest integrated health delivery network in the United States,^[2] providing care for over 8 million veterans by 180,000 medical professionals throughout the continental U.S., Alaska, and Hawaii on a single, integrated national healthcare information network of VISTA systems.^[3]

VISTA was developed by physician-developer teams within the U.S. Department of Veterans Affairs (VA), and as such has high physician user satisfaction. VISTA received the Computerworld Smithsonian Award for best use of Information Technology in Medicine in 1995, and continues to receive the highest overall physician satisfaction scores in national Electronic Health Record (EHR) surveys. In 2014 and again in 2016 national surveys of over 15,000 physician end-users of EHRs rated VISTA/CPRS the highest overall, above all other commercial EHR systems.^[4] Over 65% of all physicians trained in the U.S. rotate through the VHA and use VISTA/CPRS, making VISTA the most familiar EHR in the U.S.

Features[edit]

VISTA is a patient-centric integrated inpatient-outpatient enterprise health information system. VISTA was originally named the Decentralized Hospital Computer Program (DHCP) because it was implemented prior to the existence of the Internet when all computers were decentralized. VISTA is an integrated database and application server, and includes computerized order entry, bar code medication administration, electronic prescribing, and clinical guidelines.

Originally, VISTA had a terminal interface accessible only via a keyboard. In 1997 a Windows-based, mouse-driven graphical user interface called the Computerized Patient Record System (CPRS) was added. CPRS provides a client–server interface that allows health care providers to review and update a patient's electronic medical record. CPRS provides flexibility in a wide variety of settings so that a consistent Windows interface is presented to a broad spectrum of health care workers.

Achievements[edit]

For its development of VistA, the United States Department of Veterans Affairs (VA) / Veterans Health Administration (VHA) was named the recipient of the prestigious Innovations in American Government Award presented by the Ash Institute of the John F. Kennedy School of Government at Harvard University in July, 2006. The VistA electronic medical records system is estimated to improve efficiency by 6% per year, and the monthly cost of the EHR is offset by eliminating the cost of even a few unnecessary tests or admissions.^[5][6]

The adoption of VistA has allowed the VA to achieve a pharmacy prescription accuracy rate of 99.997%, and the VA outperforms most public sector hospitals on a variety of criteria, enabled by the implementation of VistA.^[7]

VA hospitals using VistA are one of only thirteen hospital systems that have achieved the qualifications for HIMSS stage 7, the highest level of electronic health record integration,^[8][9] while a non-VA hospital using VistA is one of only 42 US hospitals that has achieved HIMSS stage 6.^[10][11]

Licensing and dissemination[edit]

The VistA system is public domain software, available through the Freedom Of Information Act directly from the VA website^[12] or through a growing network of distributors, such as the OSEHRA VistA-M.git tree.

VistA modules and projects[edit]

Vista Start Langzaam Op Windows 10

Database backend[edit]

VistA was developed using the M or MUMPS language/database. The VA currently runs a majority of VistA systems on the proprietary InterSystemsCaché version of MUMPS, but an open source MUMPS database engine, called GT.M, for Linux and Unix computers has also been developed. Although initially separate releases, publicly available VistA distributions are now often bundled with the GT.M database in an integrated package. This has considerably eased installation. The free, open source nature of GT.M allows redundant and cost-effective failsafe database implementations, increasing reliability for complex installations of VistA.

Database projections[edit]

An open source project called EsiObjects has also allowed the (ANSI- Standard) MUMPS language and database technology to evolve into a modern object-oriented language (and persistent-object store) that can be integrated into mainstream, state-of-the-art technologies. For the Caché MUMPS database, a similar object-oriented extension to MUMPS called Caché ObjectScript has been developed. Both of these have allowed development of the MUMPS database environment (by programmers) using modern object-oriented tools.

M2Web is an open source web gateway to MUMPS for use with VistA.

A free open source module from M/Gateway called MGWSI has been developed to act as a gateway between GT.M, Cache, or M21 MUMPS databases and programming tools such as PHP, ASP.NET, or Java, in order to create a web-based interface.

Patient Web Portal[edit]

MyHealtheVet is a web portal that allows veterans to access and update their personal health record, refill prescriptions, and schedule appointments. This also allows veterans to port their health records to institutions outside the VA health system or keep a personal copy of their health records, a Personal Health Record (PHR).

VistA Imaging[edit]

The Veterans Administration has also developed VistA Imaging, a coordinated system for communicating with PACS (radiology imaging) systems and for integrating others types of image-based information, such as EKGs, pathology slides, and scanned documents, into the VistA electronic medical records system. This type of integration of information into a medical record is critical to efficient utilization.^[13]

It can be used independently or integrated into the VistA electronic health record system (as is done in VA health facilities).

Deployments and uses[edit]

Role in development of a national healthcare network[edit]

The VistA electronic healthcare record has been widely credited for reforming the VA healthcare system, improving safety and efficiency substantially. The results have spurred a national impetus to adopt electronic medical records similar to VistA nationwide.

VistA Web collectively describes a set of protocols that in 2007 was being developed and used by the VHA to transfer data (from VistA) between hospitals and clinics within the pilot project. This is the first effort to view a single patient record so that VistA becomes truly interoperable among the more than 128 sites running VistA today.

A Clinical Data Repository/Health Data Repository (CHDR) allows interoperability between the DoD's Clinical Data Repository (CDR) & the VA's Health Data Repository (HDR). Bidirectional real time exchange of computable pharmacy, allergy, demographic and laboratory data occurred in phase 1. Phase 2 involved additional drug–drug interaction and allergy checking. Initial deployment of the system was completed in March 2007 at the El Paso, Augusta, Pensacola, Puget Sound, Chicago, San Diego, and Las Vegas facilities.

VistA has been interfaced with commercial off-the-shelf products. Standards and protocols used by VA are consistent with current industry standards and include HL7, DICOM, and other protocols.

Tools for CCR/CCD support have been developed for VistA, allowing VistA to communicate with other EHRs using these standardized information exchange protocols.^[14] This includes the Mirth open source cross platform HL7 interface and NHIN Connect, the open source health information exchange adaptor.

The VistA EHR has been used by the VA in combination with Telemedicine to provide surgical care to rural areas in Nebraska and Western Iowa over a 400,000-square-mile (1,000,000 km²) area.^[15]

Usage in non-governmental hospitals[edit]

Under the Freedom of Information Act (FOIA), the VistA system, the CPRS graphical interface, and unlimited ongoing updates (500–600 per year) are provided as public domain software.^[16]

This was done by the US government in an effort to make VistA available as a low cost Electronic Health Record (EHR) for non-governmental hospitals and other healthcare entities.

With funding from The Pacific Telehealth & Technology Hui, the Hui 7 produced a version of VistA that ran on GT.M in a Linuxoperating system, and that was suitable for use in private settings. VistA has since been adapted by companies such as Blue Cliff, DSS, Inc., Medsphere, and Sequence Managers Software to a variety of environments, from individual practices to clinics to hospitals, to regional healthcare co-ordination between far-flung islands. In addition, VistA has been adopted within similar provider environments worldwide. Universities, such as UC Davis and Texas Tech implemented these systems. A non-profit organization, WorldVistA, has also been established to extend and collaboratively improve the VistA electronic health record and health information system for use outside of its original setting.

VistA (and other derivative EMR/EHR systems) can be interfaced with healthcare databases not initially used by the VA system, including billing software, lab databases, and image databases (radiology, for example).

VistA implementations have been deployed (or are currently being deployed) in non-VA healthcare facilities in Texas,^[17] Arizona,^[18] Florida, Hawaii,^[19] New Jersey,^[20] Oklahoma,^[19] West Virginia,^[21][22] California,^[23][24] New York,^[25] and Washington, D.C.^[19][26]

In one state, the cost of a multiple hospital VistA-based EHR network was implemented for one tenth the price of a commercial EHR network in another hospital network in the same state ($9 million versus $90 million for 7–8 hospitals each). (Both VistA and the commercial system used the MUMPS database).^[27]

VistA has even been adapted into a Health Information System (VMACS) at the veterinary medical teaching hospital at UC Davis.^[28]

International deployments[edit]

Vista Start Langzaam Opening

VistA software modules have been installed around the world, or are being considered for installation, in healthcare institutions such as the World Health Organization,^[21] and in countries such as Mexico,^[19][21][29] American Samoa,^[19] Kurdistan, Iraq, Finland, Jordan,^[30] Germany,^[31] Kenya,^[21] Nigeria,^[32] Egypt,^[19] Malaysia, India,^[33] Brazil, Pakistan,^[26] and Denmark.^[34]

In September 2009, Dell Computer bought Perot Systems, the company installing VistA in Jordan (the Hakeem project).^[35]

History[edit]

The name 'VistA' (Veterans Health Information System and Technology Architecture) was adopted by the VA in 1994, when the Under Secretary for Health of the U.S. Department of Veterans Affairs (VA), Dr. Ken Kizer, renamed what had previously been known as the Decentralized Hospital Computer Program (DHCP).

Both Dr. Robert Kolodner (National Health Information Technology Coordinator)^[36] and George Timson (an architect of VistA who has been involved with it since the early years) date VistA's actual architecture genesis, then, to 1977.^[37][38] The program was launched in 1978 with the deployment of the initial modules in about twenty VA Medical Centers. The program was named the Decentralized Hospital Computer Program (DHCP) in 1981.

In December 1981, Congressman Sonny Montgomery of Mississippi arranged for the Decentralized Hospital Computer Program (DHCP) to be written into law as the medical-information systems development program of the VA. VA Administrator Robert P. Nimmo signed an Executive Order in February 1982 describing how the DHCP was to be organized and managed within the VA's Department of Medicine and Surgery.

In conjunction with the VA's DHCP development, the (IHS) Indian Health Service deployed a system built on and augmenting DHCP throughout its Federal and Tribal facilities as the Resource and Patient Management System (RPMS). This implementation emphasized the integration of outpatient clinics into the system, and many of its elements were soon re-incorporated into the VA system (through a system of technology sharing). Subsequent VistA systems therefore included elements from both RPMS and DHCP. Health IT sharing between VA and IHS continues to the present day.

The U.S. Department of Defense (DoD) then contracted with Science Applications International Corporation (SAIC) for a heavily modified and extended form of the DHCP system for use in DoD healthcare facilities, naming it the Composite Health Care System (CHCS).

Meanwhile, in the early 1980s, major hospitals in Finland^[39] were the first institutions outside of the United States to adopt and adapt the VistA system to their language and institutional processes, creating a suite of applications called MUSTI and Multilab. (Since then, institutions in Germany, Egypt,^[19] Nigeria,^[32] and other nations abroad have adopted and adapted this system for their use, as well.)

The four major adopters of VistA – VA (VistA), DoD (CHCS), IHS (RPMS), and the Finnish Musti consortium^{[permanent dead link]} – each took VistA in a different direction, creating related but distinct 'dialects' of VistA. VA VistA and RPMS exchanged ideas and software repeatedly over the years, and RPMS periodically folded back into its code base new versions of the VA VistA packages. These two dialects are therefore the most closely related. The Musti software drifted further away from these two but retained compatibility with the infrastructure of RPMS and VA VistA (while adding additional GUI and web capabilities to improve function). Meanwhile, the CHCS code base diverged from that of the VA's VistA in the mid-eighties and has never been reintegrated. The VA and the DoD had been instructed for years to improve the sharing of medical information between the two systems, but for political reasons made little progress toward bringing the two dialects back together. More recently, CHCS's development was brought to a complete stop by continued political opposition within the DoD, and it has now been supplanted by a related, but different, system called AHLTA. While AHLTA is the new system for DoD, the core systems beneath AHLTA (for Computerized Physician Order Entry, appointing, referral management, and creation of new patient registrations) remain those of the underlying CHCS system. (While some ongoing development has occurred for CHCS, the majority of funds are consumed by the AHLTA project.) Thus, the VistA code base was split four ways.

Many VistA professionals then informally banded together as the 'Hardhats' (a name the original VistA programmers used for themselves) to promote that the FOIA (Freedom of Information Act) release of VA VistA (that allows it to be in the public domain) be standardized for universal usage.

WorldVistA was formed from this group and was incorporated in March 2003 as a non-profit corporation. This allowed the WorldVistA board of directors to pursue certain activities (obtaining grants, creating contracts, and making formal alliances) that they otherwise could not pursue as an informal organization. It is, however, an organization independent of the VA system and its version of VistA therefore differs from that of the VA's. Nevertheless, it maintains as an objective that its public version be compatible (interoperable) with the VA's official version. It has developed packages of WorldVistA for multiple operating systems, including Linux (Debian/Ubuntu and Red Hat) -based and Microsoft Windows-based operating systems. Co-operation with the maintainers and vendors of OpenVistA, another widely deployed open source public version of VistA, helps maintain interoperability and a standardized framework.

In 2011 the Open Source Electronic Health Record Agent (OSEHRA) project was started (in cooperation with the Department of Veterans Affairs) to provide a common code repository for VistA (and other EHR and health IT) software.^[40]

In summary, it was the joint collaboration of thousands of clinicians and systems experts from the United States and other nations, many of them volunteers, that the VistA system has developed.

Supporters of VistA[edit]

There have been many champions of VistA as the electronic healthcare record system for a universal healthcare plan. VistA can act as a standalone system, allowing self-contained management and retention of healthcare data within an institution. Combined with BHIE (or other data exchange protocol) it can be part of a peer-to-peer model of universal healthcare. It is also scalable to be used as a centralized system (allowing regional or even national centralization of healthcare records). It is, therefore, the electronic records system most adaptable to a variety of healthcare models.

In addition to the unwavering support of congressional representatives such as Congressman Sonny Montgomery of Mississippi, numerous IT specialists, physicians, and other healthcare professionals have donated significant amounts of time in adapting the VistA system for use in non-governmental healthcare settings.

The ranking member of the House Veterans Affairs Committee's Oversight and Investigation Subcommittee, Rep. Ginny Brown-Waite of Florida, recommended that the Department of Defense (DOD) adopt VA's VistA system following accusations of inefficiencies in the DOD healthcare system. The DOD hospitals use Armed Forces Health Longitudinal Technology Application (AHLTA) which has not been as successful as VistA and has not been adapted to non-military environments (as has been done with VistA).^[41]

In November 2005, the U.S. Senate passed the Wired for Health Care Quality Act, introduced by Sen. Enzi of Wyoming with 38 co-sponsors, that would require the government to use the VA's technology standards as a basis for national standards allowing all health care providers to communicate with each other as part of a nationwide health information exchange. The legislation would also authorize $280 million in grants, which would help persuade reluctant providers to invest in the new technology.^[42] There has been no action on the bill since December 2005. Two similar House bills were introduced in late 2005 and early 2006; no action has been taken on either of them, either.^[43]

In late 2008, House Ways and Means Health Subcommittee Chair Congressman Pete Stark (D-CA) introduced the Health-e Information Technology Act of 2008 (H.R. 6898) that calls for the creation of a low-cost public IT system for those providers who do not want to invest in a proprietary one.^[44]

In April 2009, Sen. John D. Rockefeller of West Virginia introduced the Health Information Technology Public Utility Act of 2009 calling for the government to create an open source electronic health records solution and offer it at little or no cost to safety-net hospitals and small rural providers.^[45][46]

VistA Derivatives[edit]

• Astronaut VistA – an installer suite for different versions of VistA, with multiple enhancements and bug fixes.
• WorldVistA or WorldVistA EHR
• OpenVistA (Medsphere)
• Osehra-Vista (OSEHRA)
• vxVistA (Document Storage Systems, Inc.)

An effort has been made by the Astronaut team, WorldVistA team, members of the VistA Software Alliance, and the OSEHRA to standardize structure between the platform derivatives to allow for future interoperability, as part of the vision for a national healthcare network record system.^{[citation needed]}
