      -THE ROLE OF RESIDENT DOCTORS
    • "It must be realized that there is nothing more difficult to plan, more uncertain of success, or more dangerous to manage than the establishment of a new order of things; for he who introduces it makes enemies of all those who derived advantage from the old order and finds but lukewarm defenders among those who stand to gain from the new one" - Niccolo Machiavelli
    • OUTLINE
        • DEFINITIONS
        • CONCEPT OF MEDICAL TECHNOLOGY
        • GROWTH OF MEDICAL TECHNOLOGY / FACTORS / VARIABLES
        • TYPES OF NEW MEDICAL TECHNOLOGY / ADVANCES
        • ROLE OF RESIDENT DOCTORS: UTILIZATION Vs IMMERSION
        • RESIDENT DOCTORS & FUTURE MEDICAL TECHNOLOGY ADVANCES
    • Preamble: Resident Doctors
        • Residency is a stage of graduate medical training
        • may follow the internship year or include the internship year as the first year of residency
        • can also be followed by a fellowship, during which the physician is trained in a sub-specialty
        • Successful completion of residency training is a requirement to practice medicine in many jurisdictions
    • Preamble: Residency
        • as an opportunity for advanced training in a medical or surgical specialty evolved in the late 19th century from brief and less formal programs for extra training in a special area of interest
        • became formalized and institutionalized for the principal specialties in the early 20th century
        • Residencies are traditionally hospital-based and in the middle of the twentieth century, residents would often live in hospital-supplied housing
      • Whereas medical school teaches physicians a broad range of medical knowledge, basic clinical skills, and limited experience practicing medicine, medical residency gives in-depth training within a specific branch of medicine
      • Medical treatment is a two step process.
        • First, the physician must diagnose a disease, and next
        • The physician must decide the course of treatment given the disease the patient is assigned
    • Preamble: Medical Technology
        • Procedures, Equipments & Processes by which medical care is delivered
        • Could be
          • New medical procedures (CI, Angioplasty, face transplant)
          • New devices (fMRI, PET, HRCT, HRMRI)
          • New support system (EMR, Telemedicine)
    • Preamble: Medical Technology
        • No area of medicine unaffected by advances in medical technology
        • Technology is a continuous piston of bearing that works on the principle of auto evolution
    • Medicine / Medical Technology Auto evolution Old Medicine specialties Subspecilties
    • Preamble: Sustainability
        • Capacity to endure
        • Potential for long term maintenance of wellbeing
        • Sustainable indicators, metrics, benchmarks necessary to set goals
          • I = PAT
          • WHERE I = environmental impact; P = population; A = affluence (level of consumption); and T = technology (impact per unit of resource)
        • Innovative Capacity Building Vs Sustainable Capacity Building
          • technology per se would be incapable of playing a major role in the achievement of sustainability or that technologies capable of delivering substantial resource productivity improvements are not, in principle, feasible
          • usual innovation processes and practices would not lead automatically to technologies compatible with sustainable development
    • Challenges of sustainability
        • The need for factor-10 to factor-50 improvement is implied
        • This challenge to be far beyond the range of improvement possible through end-of-pipe technologies and even most 'environmental' technologies, which represent process-integrated improvements to the ecoefficiency of current processes and products.
        • To have any chance of meeting the technological challenge of sustainability, it may be inadvisable to follow the traditional route of studying present products and processes as a way of identifying areas for improvement
    • This presentation is about thinking out-of-box on resident doctor's role on how to achieve sustainable capacity building towards integration of advancements in medical technology

    • Summary of Last 40 years of Medical Technology
      • As 20th century morphed into the 21st, Medical advances are aided mainly by the tripod of
        • Mechanisation
        • Automation
        • Digitalisation
    • IT Systems in HealthCare
        • IT systems only arrived in hospitals in the late 80s, today clinical and administrative processes are managed via a hospital information system (HIS), for which the clinical workstation is continuously evolving
        • Mid-80s the first digital image archives (PACS), radiology information systems (RIS) and laboratory information systems arrived
        • 1970s: immunofluorescent techniques for detecting auto-antibodies and infectious agents, and in the 1990s advances in molecular biology opened new diagnostic opportunities at the picomolar level
    • IT in Medical Technology
        • information and communication technology has not only made possible automation in the clinical lab, but all kinds of hospital practices.
        • The first patient monitoring systems, which are now taken for granted in intensive care and neonatal unit, were introduced in operating rooms and wards in the mid-1960s.
        • In the clinical laboratory, computer development made possible large-scale diagnostic tests in the 1970s
    • Medicine & Technology: Interaction - RadioSurgery
        • Uses high dose irradiation for single Rx of Brain cancers (e.g. VS, Vascular Tumours)
        • device aims gamma radiation through a target point in the patient's brain
        • ablative dose of radiation is thereby sent through the tumor in one treatment session, while surrounding brain tissues are relatively spared
        • frameless robotic radiosurgery system
        • Deliver Targeted XRT to tissues
        • The 2 main elements are
          • (1) the radiation produced from a small linear particle accelerator and
          • (2) a robotic arm which allows the energy to be directed at any part of the body from any direction
        • Gamma Knife
        • Cyber Knife
    • Gamma Knife Cyberknife
    • Medicine & Technology: Interaction - PET Scan / fMRI
      • PET Scan
        • a nuclear medicine imaging technique
        • produces a 3-D image or picture of functional processes in the body
        • The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule
        • Use in tumor imaging in ORL
      • Functional MRI
        • specialized MRI scan that measures the hemodynamic response (change in blood flow) related to neural activity in the brain or spinal cord
        • Principle known since 1890: changes in blood flow and blood oxygenation in the brain (collectively known as hemodynamics) are closely linked to neural activity
        • Use in CI Candidacy / Brain mapping / Neuro-surgical planning(oncology)
    • Brain blood flow with activity
    • PET Scan Functional MRI
    • Medicine & Technology: Interaction - Neuronavigation System
        • An offshoot of stereotactic surgery
        • Technology made possible by the advent of modern imaging techniques (CT, MRI) as well as ever increasing capabilities of digitalization, computer graphic modeling and accelerated manipulation of data through complex mathematical algorithms
        • Debuts in 1990s
        • Neuronavigation = image guidance systems consisting of the following:
          • a computer
          • a position sensor
          • a digital image of the surgical field in question � this image is obtained from CT scan and MRI scan
        • Use in ORL for skull base tumor resections, nasal and sinonasal surgeries, and otological / neurotological procedures like mastoid surgery, petrous pyramid lesions, retrosigmoid approach to the cerebellopontine angle, middle fossa approach to CPA and resection of jugular foramen.

    • From a US Medical School Survey: >1000 Med Students
        • ~90 percent - of students surveyed view the information available through mobile or online drug and disease references, such as Epocrates, as highly credible , second only to medical journals. Students also confess they are more than four times more likely to consult a mobile reference for a clinical question than ask their attending physician
        • The survey found 45 percent of respondents currently use an iPhone(TM) or iPod touch(TM), followed by Palm and Blackberry(TM)
        • Students also confess they are more than four times more likely to consult a mobile reference for a clinical question than ask their attending physician.
      Ref: Future Physicians of America survey by Epocrates
    • Open Quiz 3: What is
        • Capacity Building?
          • Assistance provided to some societies, organizations, etc especially in developing countries to enable them develop certain skill or competence?
          • An ongoing process through which societies, individuals, and organization enhance their abilities to meet developmental challenges?
      -UNDP
    • Capacity Building entails
        • Creation of enabling environments with appropriate policy and legal framework (ICT for D)
        • Institutional development, including community participation; and
        • Human Resources Development and strengthening of managerial systems
    • Sustainable Capacity Building in Immersion in Advances of Medical Technology
        • Is a long term, continuing process
        • Requires all stakeholders: residents, trainers, professional associations (NMA, MDCAN, etc), hospital and university administrators, health ministry, NGOs and development partners to participate
        • In Nigeria context, requires establishment of Nigeria Medical Informatics Association (NMIA) to spearhead
    • So What do we do?
        • Equip user populations with both the capacity and the tool to implement medical technology and derive the associated benefits
        • Enrol the current NARD leadership in global informatics mentorship program
        • Establish a regulatory infrastructure to promote the Access and Use of Medical Technology
        • Develop interest in developing Nigerian Medical Device Directory (NMDD) regulatory body
          • This should lay out basic requirement for medical device safety and performances
    • Lastly...
        • NARD can partner with Association of Computer Science Students to enhance early appreciation of challenges in health care diagnosis and treatments (e.g of Schlondorf)
        • Alternative is to encourage CSS or Clinicians to take interests in medical informatics as a carrier, and expose such to global mentorship program early enough
    • The Future can be found at the point where technologists receive specialist input, or where specialists become imbued with technological knowhow
    •
