22 Feb 2010 "Rural Doctors Find Benefit in Electronic Health Records" by: Milt Freudenheim www.nytimes.com ITGS Triangle- Area of Impact: health Social and Ethical issues: equality of access, global and cultural diversity; electronic health records allow patients' information to be more easily accessed by professionals. IT system: Electronic Health Records Stakeholders: Patients and professional health-care workers. Professionals can share and access patient information more easily and readily. Presentation of Issue-- If a professional cannot switch to electronic health records, they are at a disadvantage. The playing field is not even for all professionals. Some professionals were switching their written records to electronic records to make access and use of records easier. While some professionals made the switch, others were having difficulty succeeding. This issue affected some doctors severely. For example Dr. Michael Ferris had a problem with his expensive system continuing to crash. This put his practice in jeopardy.

In this article, RFID is being used in the business world. People are now able to purchase phones with the capability of making purchases by moving it over the terminal. RFID technology allows people to stop using credit cards, making the process of buying something even more convenient. The stakeholders are the credit card companies, the people using this new technology, and the stores with the terminals that read RFID. Credit card companies need to have a good security system to ensure their customers and users that their information will be kept safe on the RFID chip. The people who are switching to this new technology are risking their private information for convenience. The stores with these new RFID terminals are also risking their customers' private information because there is a possibility that their system could be hacked. The area of impact is Business and Employment. Businesses are switching to this new technology because it is convenient for them as well as their customers. The main issues that arise from using RFID are security and reliability. The RFID terminal needs to be reliable so that every customer is able to use the RFID chip on their phone to make purchases. The security issue is that a hacker may be able to get into the system to read customers' private information. It may also be possible for a hacker to carry around a portable terminal that would be able to store people's private information on it for future usage. The security system described in this article sounds like a good start, but more needs to be done to keep up with the technology that is growing along with it.

"nce a week at a pre-arranged time, Olive sets up the complicated looking equipment her end. She then phones Victor to make sure he is ready to receive her call and that his computer is switched on. She then calls him up, and they have a face-to-face consultation. While Victor sits on his bed in his semi-detached home in Middlesex, Olive can check his breathing, heart rate and temperature and watch out for any early signs that his body is rejecting his double lung transplant. "This allows us to be there for him," Olive said. "

"A Pennsylvania school district accused of secretly switching on laptop computer cameras inside students' homes is under investigation by federal authorities, a law enforcement official with knowledge of the case said."

Airlines and EU officials said the security risk will be minimized because the system will not connect inflight phones directly to the ground - instead using an onboard base station to link up to a satellite and then to ground networks. "It has to go through a central onboard cellular network that can be switched off by the captain at any moment, so that enhances the security of the passengers," said EU spokesman Martin Selmayr. He added that for safety and security concerns the phone services will not be available during takeoff, landing or during turbulence.

"Another primary school in Northern Ireland has decided not to use wireless technology after a parent cited health fears, it has emerged."

This article deals with the use of electronic health records in order to record medical information of patients. Congress wishes to pass a bill to enforce the use of electronic health records, however issues regarding the privacy of patients and information stored on these databases have arose. Electronic health records are used to record personal patient information such as name, age, address along with health sicknesses and symptoms. This also allows doctors to send e-prescriptions to the patient. However the computerization of health records triggers obvious privacy issues which prevent many hospitals to completely switch to using these electronic databases. Stakeholders of this technology include the patients whose medical information is being stored and sent on the databases, the hospitals and doctors that use the databases to track and send prescriptions to their patients, along with policy makers such as Congress and President Obama who promote the use of electronic health databases. The major stakeholder is the patient, whose private information is at risk by using these databases. Doctors can also use the electronic databases to send prescriptions to their patients for medicines or further appointments. Patient databases include sensitive personal information that may be at risk of being hacked or seen by an unauthorized user. In the article, solutions to these privacy issues have been proposed such as increased spending and investments in order to create solutions to privacy issues. Measures can be taken to safeguard medical information such as using encryption technology to secure private information that is sent online or kept on the hospital's computer database. This encryption would prevent unauthorized users from accessing and using patient information. However, in cases where this encryption technology fails to protect patient information, policies have been created that the patient must be notified if their personal information has been h

Other policies have been enforced that give patients the ability to control and prevent hospitals from sending private information for research without their permission. These policies help prevent private patient information from being seen by unwanted individuals.

The article starts with a general overview of telemedicine and its roots in NASA. Then, the article switches the focus to the implementation of telemedicine in Haiti. The establishment of networks in Haiti immediately benefited the effort to recover. Communication came immediately, but telemedicine found its way into Haiti and held a crucial role in recovery. Video sessions became common, allowing simpler analysis of data and training of doctors.
