Implications Established ultrasound training programs Residency programs for Emergency Medicine incorporate ultrasound training in the US. Implementing ultrasound in care for > 20 years. American College of Emergency Physicians (ACEP) Need for emergency ultrasound imaging on a 24-hour basis and that emergency room physicians should perform such examinations.(2001) 16-hour initial comprehensive course with foundation in emergency ultrasound ≥ 25 -50 documented, reviewed cases in each primary application: Trauma, IUP, Emergency Cardiac, AAA, Biliary, Renal, DVT, Vascular Access, etc. Implications Documented 15% decrease in length-ofstay of patients with gallbladder examinations for experienced physicians (>100 gallbladder scans) compared with on-call sonographer.

Importance Organized training for physicians by physicians Guidelines for TEE training through residency Guidelines for nerve block training through residency Ultrasound Is… Ultrasound is… Pattern recognition Today’s Imaging We see a mass and we look for size, shape, location. We can get growth data. What if: – We could establish whether or not the mass is malignant? – What if the ultrasound were capable of distinguishing a pattern of a disease process from a normal person? Futuristic Use of Ultrasound Delivery of therapeutic drugs directly into the body where they need to be – Selective introduction of drugs into diseased tissue – Activated by sound – Sonoluminescene (light from sound) dates to 1930, but technology is coming to age – May be ten years away – Don Baker, December 31, 2008 SDMS News Wave 4D Ultrasound Contrast Detection of liver mets Improved imaging with cirrhosis Potential for assessment of buried grafts following oropharynx surgery Screen for calf peripheral artery disease Malignant vs. benign renal tumors Imagify Declined by FDA November 2008 The product was administered to 1,194 subjects, including 911 patients with known or suspected coronary artery disease – 1% (11/911) reported serious adverse events 3 patients experienced vasovagal syncope. – 4% (38/911) experienced hypotension or decreased blood pressure – 2% (16/911) had exam permanently discontinued because of adverse events.

Free membership http://www.sonoworld.com/sonoworld/icus/ Forms/ICUS_Letter-Form.PDF Fusion Imaging Researchers are working to perfect a fusion of technologies to provide imaging: Non-ionizing Higher doses to the tumor and periphery Accurate daily patient positioning Dose escalation in a given session Real-time targeting of tumors and tumor beds Image-fusion between various visualization modes (MRI, Ultrasound) On-line treatment planning procedures/protocols High Intensity Focused Ultrasound to fight Cancer The new findings from animal experiments suggest that once activated by the ultrasound, the immune system might even seek and destroy cancer cells , including those that have spread through the bloodstream to lurk in other parts of the body. This high-intensity focused ultrasound, or HIFU, is in use or testing in China, Europe and the United States to kill tumors by heating them. But Duke researchers now find that HIFU might work even better if it is first delivered in a manner that just shakes the cells. That shaking ruptures tumor cell membranes, causing them to spill their contents. The toxic spill then alerts the immune system to the cancer threat, leading to the production of tumor-fighting white blood cells. http://www.physorg.com/news105711171.html Elastography A non-invasive method in which stiffness or strain images of soft tissue are used to detect or classify tumors. A tumor or a suspicious cancerous growth is normally 5-28 times stiffer than the background of normal soft tissue. When a mechanical compression or vibration is applied, the tumor deforms less than the surrounding tissue.

Documentation by sonographers, with interpretation by a trained physician medically necessary. Physicians tend to see the strengths. Ultimately gain respect for ultrasound. Outlook – RDMS Job growth is expected Sonography becomes an increasingly attractive alternative, as patients seek safer treatment methods. Sonographic technology is expected to evolve rapidly. Hospitals will remain the principal employer of diagnostic medical sonographers. Employment is expected to grow more rapidly in offices of physicians and in medical and diagnostic laboratories, including diagnostic imaging centers. http://www.bls.gov/oco/ocos273.htm Outlook – CardioVascular Growth will occur as the population ages, because older people have a higher incidence of heart disease and other complications of the heart and vascular system. Procedures such as ultrasound are being performed more often as a replacement for more expensive and more invasive procedures. Employment of vascular technologists and echocardiographers will grow as advances in vascular technology and sonography reduce the need for more costly and invasive procedures. http://www.bls.gov/oco/ocos100.htm Lab Radiography Respiratory Therapist EMT ↓ Diagnostic Medical Social Workers RN Occupational Therapist Radiation Therapist Health Educators 30% Cardiovascular Technologist Physical Therapist PA Dental Hygenist Comparisons 2006-2016 Outlook 35% ↓ 25% 20% 15% 10% 5% 0% The Future of Ultrasound By all appearance, is very strong. RDMS: Employment change. is expected to increase by about 19 percent through 2016— faster than the average for all occupations—as the population ages. RDCS/RVT: Employment is expected to increase by 26 percent through the year 2016, much faster than the average for all occupations. Registry vs. License Registry vs. License Code of Virginia 54.1-100 Regulations of professions and occupations. The right of every person to engage in any lawful profession, trade or occupation of his choice is clearly protected by both the Constitution of the United States and the Constitution of the Commonwealth of Virginia. The Commonwealth cannot abridge such rights except as a reasonable exercise of its police powers when it is clearly found that such abridgment is necessary for the preservation of the health, safety and welfare of the public. Code of Virginia, cont. No regulation shall be imposed upon any profession or occupation except for the exclusive purpose of protecting the public interest when: The unregulated practice of the profession or occupation can harm or endanger the health, safety or welfare of the public, and the potential for harm is recognizable and not remote or dependent upon tenuous argument; The practice of the profession or occupation has inherent qualities peculiar to it that distinguish it from ordinary work and labor; The practice of the profession or occupation requires specialized skill or training and the public needs, and will benefit by, assurances of initial and continuing professional and occupational ability; and The public is not effectively protected by other means Registry vs. License “States disinterested.” SDMS has pushed for NATIONAL credentialing to avoid the state issues – – – – – Licensure board representation Additional licensure fees 50 different laws State tests vs national tests Problems with reciprocity – moving from one state to another, etc. – Denise Lewis, Society of Diagnostic Medical Sonography – February 23, 2009 License vs. Registered Mandatory minimum qualifications Protects the consumer Minimum standards for practice defined by law Sets timetable for phasing out those who do not meet the requirements Identifies qualified sonographers May enhance profession image of sonographers Drive educational programs to seek accreditation Allows access for statistical and records about sonographer May reduce costs associated with repeated examinations from suboptimal testing Annitta J.
