The Past of EHRs
Electronic Health Records
EHRs are designed to contain and share patient information for the purpose of delivering health care services.
Can be created, managed, and consulted by authorized providers and staff across more than one health care organization.
Allows patients records to move with them to other providers, nursing homes and across states.

Medical Technology
What is Medical Technology?
Practical application of the scientific body of knowledge in order to:

Improve health

Create efficiencies in the delivery of health care

Information Technology:

Deals with the transformation of data into useful information.

Examples: clinical information Systems (Electronic Medical Records Systems),administrative information systems (Billing), and decision support systems CPOE (computerized physician order entry). Reduction of medical errors.

Advantages of EHRs
Improved Health Care Quality and convenience for providers
Improve Information Availability
Support Provider Decision Making
Improve accessibility of record for provider, patients, and family caregivers
1920s: Medical records were documented on paper by “record librarians."
1960 & 1970s: American universities began exploring ways for combining computer and medical records.
1980s: For the first time, patients use computerized check in. Medical record departments start using the master patient index (MPI).
1990s: Computer applications were used within healthcare but none of them could associate,be viewed by other departments, and most used their own computer hardware.
2000: Re-emphasis for EHRs emerges due to medical errors and increasing numbers of patient deaths and injuries caused by healthcare providers.

Laws & Incentives
Confidentiality & Security Concerns
Health Insurance Portability and Accountability Act,(HIPPA)of 1996 protects
The privacy of individually identifiable health information or PHI.
Ensures confidentiality & integrity of all PHI that is created, received, maintained or transmitted.
Ensures compliance by workforce.
Breach Notification Rule: requires providers to notify individuals of loss,theft,or other unauthorized disclosures of unsecured PHI.
Reduce Risk to PHI
Three Safeguards
Develop policies & procedures
Internal audits
Define levels of access and Provide training

Secure location and workspace
Develop policies for verifying access authorizations, equipment control, and handling visitors.
Provide protection against fire and other hazards

Unique user id, passwords & pin numbers
Automatic log off
Encryption controls
In the past, each hospital department purchased and installed software tailored to that specific department's function.
As EHRs became more sophisticated, they tried to link each of the internal departments together.
The hospital’s EHR is locally-housed.
Large multi-hospital systems, modifications can cost billions of dollars.

Non-invasive Medical Procedures
Invented in 1968 in Sweden where the first clinical treatment was delivered, the first U.S. unit was installed in 1988 at the University of Pittsburgh
Approved by the FDA in 1988.
Gamma Knife® is not a knife at all. No scalpels.
Stereotactic radiosurgery (SRS) Stereotactic refers to precise positioning in three-dimensional space. In Gamma Knife surgery, this means a 3-D reference frame is attached to the patient’s head during the procedure. 
Non-invasive method for treating brain disorders.

Why is Gamma Knife Used?
Patients for whom traditional brain surgery is not an option

AVM (Arteriovenous Malformation)
Trigeminal Neuralgia
Brain Tumors:
Acoustic Neuroma
Pituitary Adenoma  
Brain Metastasis

Pituitary Tumor
Swelling of the brain

Gamma Knife® is a neurosurgical tool designed exclusively for the treatment of brain disorders.
The lesion being treated receives a high dose of radiation with minimum risk to nearby tissue and structures.
The cost of a Gamma Knife® procedure is often 25% to 30% less than traditional neurosurgery.
Patients experience little discomfort.
The absence of an incision eliminates the risk of hemorrhage and infection.
Hospitalization is short, typically an overnight stay or an outpatient surgical procedure. Patients can immediately resume their previous activities.
Gamma Knife® technology allows treatment of inoperable lesions. The procedure offers hope to patients who were formerly considered untreatable or at very high risk during open skull surgery.

How is The Surgery Done?
The Head Frame
Imaging: MRI, CT, Angiography
Treatment Planning
The Treatment

The treatment effect of Gamma Knife radiosurgery occurs gradually, depending on the condition being treated:

Benign tumors.
Gamma Knife radiosurgery results in the failure of tumor cells to reproduce. The tumor may shrink over a period of 18 months to two years, but the main goal of Gamma Knife radiosurgery for benign tumors is to prevent any future tumor growth.

Malignant tumors.
Cancerous (malignant) tumors may shrink more rapidly, often within a few months.

Arteriovenous malformations (AVMs)
. The radiation therapy causes the abnormal blood vessels of brain AVMs to thicken and close off. This process may take two years or more.

Trigeminal neuralgia
. Gamma Knife radiosurgery creates a lesion that blocks transmission of pain signals along the trigeminal nerve. Pain relief may take several months.

A picture is worth a thousand words.

More vs. Less space.
Documents needed would have to be recovered from a huge warehouse then mailed or scanned and sent via e-mail which is time consuming.
Readability and Accuracy:
Paper records don’t necessarily have enough space for physician’s to write down all the necessary information and since all the information is written it is also difficult to understand the majority of the information.

The Future of EHRs:
Smart Card Technology

Germany & Austria
Since 2006, the smart card eGK is used.
Enables secure data storage.
Two cards involved.
-1st card: Holds patient specific applications & prescriptions.
-2nd card: Issued to healthcare professionals

In 1998/1999, France distributed smart cards to each family.
In 2006, Carte Vitale 2 cards given with enhanced security features and larger memory.

United States
St.Thomas Hospital in Nashville, TN uses smart card with patient's ID, medical history, personal and insurance information.
VA Hospitals have immediate access to patient files by inserting a smart card and entering a password.

What do these numbers mean?

It means we do not have enough donors
to cover the demands of recipients waiting
for organ transplants!

It means we need to find alternative
sources to donated organs!

8/2000 FDA approves for
for use in transplant

Started in 1994

April 1997 FDA approves
for use in transplant

The first successful lung transplant, performed on Nov. 7, 1983 at Toronto General Hospital on Tom Hall. He survived 6 years after his transplant.

Lung Transplant

The first Liver Transplant was performed in 1963.

Julie Rodriguez, transplanted in 1967, was the first Liver Transplant recipient to exceed survival of one year.

Liver Transplant

First Successful Kidney Transplant –
December 23rd, 1954 – Identical Twins- Ronald Herrick donated to Richard Herrick and succeeded because they were genetically identical.

How many people are still waiting for an
organ transplant in the United States?

Today intestinal transplants are also sometimes combine with other abdominal organs, known as a Multi-visceral Transplant.
First performed in 1983 By Dr T. Starzl on a 6 year old at The University of Pittsburgh Medical Center.

1988 – First successful Small
Intestine transplant
performed in Kiel, Germany.

Intestinal & Multi-Visceral

First Heart Transplant was performed in 1967
in Cape Town, South Africa, Dr C. Barnard,
on recipient Louis Washkansky, who only survived
18 days, dying of rejection.

The first successful Heart Transplant didn’t occur
until 1977 at Columbia University Medical Center
in New York. That patient survived 14 months.

In 1984, the world's first successful pediatric heart
transplant was performed at Columbia University
Medical Center on a four-year-old boy. He received
a second transplant in 1989 and continues to
live a productive life today.

Heart Transplant

Cyclosporine - First truly effective
immunosuppressive/anti rejection
medication. 1983 FDA approves for
use in transplant recipients,
dramatically reducing rates of
rejection and increasing
long term survival rates.

1968 FDA approves for use in transplant recipients.
Helpful but most recipients still died from rejection.

Primary Immunosuppression/Anti-Rejection Medications

Dialysis started in 1943. It is still the leading treatment
for patients awaiting Kidney transplant.
Increase oxygen use.
Surgery to remove a portion of or whole diseases organs.

Increase medication dosages to maintain organ functionality and pain relief for the patient.

What Was Done Before Transplant?

1968 The Southeast Organ Procurement Foundation (SEOPF) is formed as a membership and scientific organization for transplant professionals.
1984 United Network for Organ Sharing (UNOS) separates from SEOPF.
1986 UNOS receives the initial Federal contract to operate
the Organ Procurement and Transplantation Network
(OPTN). Continuing their Federal Contract to the
UNOS raises awareness about organ donation.
Establishes equitable policies.
Maintains the National Transplant Waiting List.
Maintains a scientific registry.
Facilitates organ distribution and transplantation.
Monitors members for compliance with Federal policies including HIPPA.

Who Controls Organ
Donation & Transplant?





Large & Small

Solid Organs for Transplant

As of 4:25pm on 10/19/2014 - 123,878 people need a lifesaving organ transplant (total waiting list candidates). Of those, 79,325 people are active waiting list candidates.
January to July 2014- 16,883 transplants performed.
January to July 2014- there were 8,277 donors.

What is the Appendix?
: The appendix is a tube-shaped, sacklike organ, situated in the right-hand part of the abdomen and is attached to the lower end of the large intestine.
No Known Function!!!
Acute Appendicitis:
A condition in which the appendix becomes infected and inflamed.
-If perferation or rupturing occurs, it must be removed before the infection spreads into the entire abdominal space.

One of the
most common
causes of emergency surgury.
- 1/2,000 people has an appendectomy at some point in their life.
Abdominal pain
Loss of appetite
Nausea and Vomiting

Rebound-tenderness test
Pull of Leg

and Prothetics
Orthotics and Prosthetics (O&P) is the evaluation, fabrication, and custom fitting of artificial limbs and orthopedic braces.
Orthotics is the branch of medicine that deals with the provision and use of artificial devices such as prosthetic,splints, and braces.
Over 200,000 people in the United Stated us a prosthetic of some kind.
1902- while at The University of Lyon- France,
published the technique of vessel suture
now known as “Carrell’s seam”.
The Nobel Prize in Physiology or Medicine 1912
“ In recognition of his work on vascular
suture and the transplantation of blood
vessels and organs”
With out his work in the study vascular suturing-
modern organ transplant would not
be possible

Dr Alexis Carrel

Lungs at one time, could only be out of the
body, for a maximum of 4-5 hours while being stored
in an ice cold preservation solution.
August 12, 2014- FDA approves XVIVO Lung Perfusion
Preservation system developed out of
Englewood, CO.
This new preservation system will now allow lungs to
remain out side the body for up to 11 hours- this
will allow doctors to further examine the lungs before
transplant. It will also allow for greater distance of
travel to procure them and almost double the
available population of possible donors.

New Advancement in
Organ Preservation

Prosthetic – a prosthetic is an artificial body part.
There are many different types of prosthetics. The kind used depends on the placement and functionality necessity. The most common are:
Joint Prosthetics
Arm/Hand Prosthetics
Leg/Foot Prosthetics
Cosmetic Prosthetics
Cosmetic prosthetics often encompass both cosmetics and functionality but can be purely cosmetic.
Cosmetic Prosthetics
Causes For Prosthetic Needs
Amputation of a limb is the main reason requiring a prosthetic. The most common cause of amputation is poor circulation caused by damage or narrowing of the arteries, called peripheral arterial disease. Aside from amputation other causes may include severe injury (from MVA, burn, etc.), cancerous tumor in the bone or muscle of the limb, serious infection, and frostbite.
Restoration of functionality is another common reason (joint replacement.)

Advantages of
Using A Prosthetic
Restores functionality of a limb by replacement of a worn out joint.
Replaces an amputated or decapitated limb or body part.
Provides comfort to someone who has suffered a trauma where, although the prosthetic is
not a necessity, it offers the user the opportunity to resume a normal life.
The Cost
of Prosthetics
The average cost of a leg prosthetic can range between $5,000 and $50,000 depending on the functionality and materials. The average cost of an arm prosthetic between $3,000 and $30,000. However, even the most expensive prosthetic limbs are built to withstand only three to five years of wear and tear. Making the lifetime total much higher.
This price is influenced by materials such as stronger, less dense alloys and plastics, carbon fiber and aesthetics.
Also, whether or not technology plays a role in the prosthetic.
Who Pays
These Costs?
Private Insurance
Private and Non-Profit Organizations
More Organizations Available for Children

Prosthetics in the
In the past, prosthetics were made of fiber, wood, iron, and bronze.
After the Civil War, a need for more practical and more easily available artificial limbs was a necessity. At this point, the US government started funding the production of artificial limbs.
In the past half century, artificial limbs started becoming more life-like and using lighter and more durable materials.
Now-a-days, prosthetics have made exponential improvements in functionality and durability. They now use materials such as carbon fiber and have highly improved attachment methods. The addition of microprocessors and other computer-aided designs further improve the use and functionality of prostheses.
They now have sensors which detect nerve impulse causing the prosthetic to function as a natural arm would.
Scientists are now working on prosthetics that may include sensory reception as well. This would allow the recipient to feel temperature and moisture changes to prevent accidental damage to the prosthetic as well as provide a "feel of normality" for the wearer.
