Step 1 of 3

Chapter 4 - Health professionals are among the most well education and diverse of all labor groups - Physicians play a central role by evaluating a patient’s health condition, diagnosing abnormalities and prescribing treatment. - All physicians must be licensed to practice.- graduation from an accredited medicial school that awards an MD or DO, completion of licensing examination, completetion of residency/internship program - Residency- refers to graduate medical eduction in a speciality that takes the form of paid-on-the-job traning - Osteopathic medicine- practiced by Dos, emphasizes the musculoskeletal system of the body, such as correction of joints or tissues. In treatment plans, DOs stress preventive medicine and how factors like diet and environment, might influence natural resistance, take holistic approach - MDs use allopathic medicine- medicine is active intervention to produce a counteracting reaction in an attempt to neutralize the effects of disease. May use preventive medicine - DO’s are generalist and MD’s are specialists - Family medicine/general practice, general internal medicine and general pediatrics- primary care physicians/generalists - Physicians in nonprimary care specialities are referred to as specialists - Medical specialities: the subspecialties of internal medicine, a broad group of medical specialties, obstetrics and gynecology, surgery of all types, hospital-based radiology, anesthesiology, pathology, and psychiatry - Primary care vs. Specialty care: 1. Primary care is first-contact care (portal to health care system). Specialty follows primary 2. Primary care physicians are gatekeepers- control cost, utilization and rational allocation of resources. Specialty requires referral from primary 3. Primary is more routine, speciality is focused and episodic 4. Primary focuses on person as a whole. Specialty focuses on specific disease 5. Primary care students spend time learning about a variety of patient conditions and problems; specialty students learn in inpatient hospitals, and are exposed to medical technology - comorbidity- patient has multiple problems - hospitalists- physicans who specializer in the care of hospitalized patients - the principal source of funding for graduate medical education is the medicare program- provides explicit payments to teaching hospitals for each resident in training - Hospital based training has increased the amount of specialists - Health care delivery system is evolving toward primary care orientation - Medical traning model focuses on acute interventions - The ACA is going to invest money to increase the number of medical residents, NP’s and physician assistants trained in primary care - Maldistribution- surplus or shortage of the type of physicians needed to maintain the health status of a given population at an optimum level. - Surpluses result in increased health care expenditures without a positive return in health outcomes - Dentists- must be licensed- graduation from an accredited dental school, completion of both written and practical examinations - Dental hygienists work in dental offices and provide preventive dental care, including cleaning teeth and education patients on proper dental care. - Dental assistants work for dentists in preparation, examination, and treatment of patients- don’t have to be licensed. - Pharmacists are generalists- dispensing drugs and advising providers and patients - Omnibus Budget Reconciliation Act of 1990- pharmacists are required to give consumers information about drugs and their potential misuse—pharmaceutical care - Pharmaceutical care- a mode of pharmacy practice in which the pharmacist takes an active role on behalf of patients, by assisting prescribers in appropriate drug choices, by effecting distribution of medications to patients, and by assuming direct responsibilities collaboratively with other health care professionals and with patients to achieve the desired therapeutic outcome - Optometrists provide vision care, such as examination, diagnosis, and correction of vision problems - Psychologists provide patients with mental health care. - Podiatrists treat patients with disease or deformities of the feet - Chiropractors provide treatment to patients through chiropractic manipulation, physiotherapy, and dietary counseling - Register nurses must complete an associate’s degree, a diploma program, or a BSN - Licensed practical nurses most complete a state- approved program in practical nursing and a national written exam. - Advanced practice nurse- a general classification of nurses who have education and clinical experience beyond that required of an RN (CNS, CRNAS, NP, CNM) - CNSs v. NPs- CNSs work in hospitals, NPs are in primary care settings. - Nonphysician practitioners refer to clinical professionals who may practice in many areas similar to those in which physicians practice but do not have an MD or DO degree, also referred to as physician extenders because in the delivery or primary care, they can substitute for physicians. - Nurse practitioners- individuals who have completed a program of study leading to competence as RNs in an expanded role., work mostly in primary care - PA’s are spilt between primary and specialty care. NPs are oriented toward health promotion and education, PA’s are oriented more toward a practice model that focuses on disease. - PA’s can perform medical procedures under the supervisions of a physician who may be on site or off site - Allied health- health related technical areas: two divisions- technicians/assistants and therapists/technologists - PT’s provide care for patients with movement dysfunction - OT’s help people of all ages improve their ability to perform tasks in their daily living and working environments Chapter 4 - Health professionals are among the most well education and diverse of all labor groups - Physicians play a central role by evaluating a patient’s health condition, diagnosing abnormalities and prescribing treatment. - All physicians must be licensed to practice.- graduation from an accredited medicial school that awards an MD or DO, completion of licensing examination, completetion of residency/internship program - Residency- refers to graduate medical eduction in a speciality that takes the form of paid-on-the-job traning - Osteopathic medicine- practiced by Dos, emphasizes the musculoskeletal system of the body, such as correction of joints or tissues.
