Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Emergency medicine is the medical speciality concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency physicians specialize in providing care for unscheduled and undifferentiated patients of all ages. As first-line providers, in coordination with emergency medical services, they are primarily responsible for initiating resuscitation and stabilization and performing the initial investigations and interventions necessary to diagnose and treat illnesses or injuries in the acute phase. Emergency medical physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, and tertiary care, as well as in public health.
Palliative care is an interdisciplinary medical caregiving approach aimed at optimizing quality of life and mitigating suffering among people with serious, complex, and often terminal illnesses. Within the published literature, many definitions of palliative care exist. The World Health Organization (WHO) describes palliative care as "an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial, and spiritual". In the past, palliative care was a disease specific approach, but today the WHO takes a broader patient-centered approach that suggests that the principles of palliative care should be applied as early as possible to any chronic and ultimately fatal illness. This shift was important because if a disease-oriented approach is followed, the needs and preferences of the patient are not fully met and aspects of care, such as pain, quality of life, and social support, as well as spiritual and emotional needs, fail to be addressed. Rather, a patient-centered model prioritizes relief of suffering and tailors care to increase the quality of life for terminally ill patients.
Primary care is the day-to-day healthcare given by a health care provider. Typically this provider acts as the first contact and principal point of continuing care for patients within a healthcare system, and coordinates other specialist care that the patient may need. Patients commonly receive primary care from professionals such as a primary care physician, a physician assistant, a physical therapist, or a nurse practitioner. In some localities, such a professional may be a registered nurse, a pharmacist, a clinical officer, or an Ayurvedic or other traditional medicine professional. Depending on the nature of the health condition, patients may then be referred for secondary or tertiary care.
Telehealth is the distribution of health-related services and information via electronic information and telecommunication technologies. It allows long-distance patient and clinician contact, care, advice, reminders, education, intervention, monitoring, and remote admissions. Telemedicine is sometimes used as a synonym, or is used in a more limited sense to describe remote clinical services, such as diagnosis and monitoring. When rural settings, lack of transport, a lack of mobility, conditions due to outbreaks, epidemics or pandemics, decreased funding, or a lack of staff restrict access to care, telehealth may bridge the gap as well as provide distance-learning; meetings, supervision, and presentations between practitioners; online information and health data management and healthcare system integration. Telehealth could include two clinicians discussing a case over video conference; a robotic surgery occurring through remote access; physical therapy done via digital monitoring instruments, live feed and application combinations; tests being forwarded between facilities for interpretation by a higher specialist; home monitoring through continuous sending of patient health data; client to practitioner online conference; or even videophone interpretation during a consult.
Community health refers to simple health services that are delivered by laymen outside hospitals and clinics. Community health is also the subset of public health that is taught to and practiced by clinicians as part of their normal duties. Community health volunteers and community health workers work with primary care providers to facilitate entry into, exit from and utilization of the formal health system by community members.
Health equity arises from access to the social determinants of health, specifically from wealth, power and prestige. Individuals who have consistently been deprived of these three determinants are significantly disadvantaged from health inequities, and face worse health outcomes than those who are able to access certain resources. It is not equity to simply provide every individual with the same resources; that would be equality. In order to achieve health equity, resources must be allocated based on an individual need-based principle.
Immigrant health care in the United States refers to the collective systems in the United States that deliver health care services to immigrants. The term "immigrant" is often used to encompass non-citizens of varying status; this includes permanent legal residents, refugees, and undocumented residents.
Health literacy is the ability to obtain, read, understand, and use healthcare information in order to make appropriate health decisions and follow instructions for treatment. There are multiple definitions of health literacy, in part, because health literacy involves both the context in which health literacy demands are made and the skills that people bring to that situation.
Video remote interpreting (VRI) is a videotelecommunication service that uses devices such as web cameras or videophones to provide sign language or spoken language interpreting services. This is done through a remote or offsite interpreter, in order to communicate with persons with whom there is a communication barrier. It is similar to a slightly different technology called video relay service, where the parties are each located in different places. VRI is a type of telecommunications relay service (TRS) that is not regulated by the FCC.
The doctor–patient relationship is a central part of health care and the practice of medicine. A doctor–patient relationship is formed when a doctor attends to a patient's medical needs and is usually through consent. This relationship is built on trust, respect, communication, and a common understanding of both the doctor and patients' sides. The trust aspect of this relationship goes is mutual: the doctor trusts the patient to reveal any information that may be relevant to the case, and in turn, the patient trusts the doctor to respect their privacy and not disclose this information to outside parties.
Clinical pharmacy is the branch of pharmacy in which clinical pharmacists provide direct patient care that optimizes the use of medication and promotes health, wellness, and disease prevention. Clinical pharmacists care for patients in all health care settings but the clinical pharmacy movement initially began inside hospitals and clinics. Clinical pharmacists often work in collaboration with physicians, physician assistants, nurse practitioners, and other healthcare professionals. Clinical pharmacists can enter into a formal collaborative practice agreement with another healthcare provider, generally one or more physicians, that allows pharmacists to prescribe medications and order laboratory tests.
Health communication is the study and practice of communicating promotional health information, such as in public health campaigns, health education, and between doctor and patient. The purpose of disseminating health information is to influence personal health choices by improving health literacy. Health communication is a unique niche in healthcare that allows professionals to use communication strategies to inform and influence decisions and actions of the public to improve health.
Asian Americans have historically been perceived as a "model minority", experiencing few health problems relative to other minority groups. Research within the past 20 years, however, has shown that Asian Americans are at high risk for hepatitis B, liver cancer, tuberculosis, and lung cancer, among other conditions. Asian American health disparities have only gained focus in the past 10 years, with policy initiatives geared towards promoting healthcare access to Asian Americans rising to prominence even later. Asian Americans are defined as Americans of Asian ancestry and constitute nearly 5% of American's population as of 2003, according to the U.S. Census Bureau. Yet, the Asian American population can hardly be described as homogenous. The term applies to members of over 25 groups that have been classified as a single group because of similar appearances, cultural values, and common ethnic backgrounds. The Asian Americans commonly studied have been limited primarily to individuals of Cambodian, Chinese, Filipino, Hmong, Japanese, Korean, Lao, Mien, or Vietnamese descent.
Patient satisfaction is a measure of the extent to which a patient is content with the health care which they received from their health care provider.
Cultural competence in healthcare refers to the ability for healthcare professionals to demonstrate cultural competence toward patients with diverse values, beliefs, and feelings. This process includes consideration of the individual social, cultural, and psychological needs of patients for effective cross-cultural communication with their health care providers. The goal of cultural competence in health care is to reduce health disparities and to provide optimal care to patients regardless of their race, gender, ethnic background, native languages spoken, and religious or cultural beliefs. Cultural competency training is important in health care fields where human interaction is common, including medicine, nursing, allied health, mental health, social work, pharmacy, oral health, and public health fields.
Canopy is a digital health company, established in 2010 and headquartered in New York, NY. Its technologies focus on bridging the linguistic and cultural barrier between healthcare providers and their limited English proficiency, or non-English speaking patients.
Undertreatment of pain is the absence of pain management therapy for a person in pain when treatment is indicated.
Special considerations are needed to provide appropriate medical treatment for refugee migrants to the United States, who often face extreme adversity, violent and/or traumatic experiences, and travel through perilous regions. Such considerations include screenings for communicable diseases, vaccinations, posttraumatic stress disorder, and depression.
