Risk Of Mortality
The risk of mortality (ROM) provides a medical classification to estimate the likelihood of in-hospital death for a patient. The ROM classes are minor, moderate, major, and extreme. The ROM class is used for the evaluation of patient Death, mortality. See also * Case mix index * Diagnosis codes * Severity of illness References * Alemi, F., J. Rice, and R. Hankins. 1990.

Medical Classification
A medical classification is used to transform descriptions of medical diagnoses or procedures into standardized statistical code in a process known as clinical coding. Diagnosis classifications list diagnosis codes, which are used to track diseases and other health conditions, inclusive of chronic diseases such as diabetes mellitus and heart disease, and infectious diseases such as norovirus, the flu, and athlete's foot. Procedure classifications list procedure codes, which are used to capture interventional data. These diagnosis and procedure codes are used by health care providers, government health programs, private health insurance companies, workers' compensation carriers, software developers, and others for a variety of applications in medicine, public health and medical informatics, including: * statistical analysis of diseases and therapeutic actions * reimbursement (e.g., to process claims in medical billing based on diagnosis-related groups) * knowledge-based an ...

Likelihood
A likelihood function (often simply called the likelihood) measures how well a statistical model explains observed data by calculating the probability of seeing that data under different parameter values of the model. It is constructed from the joint probability distribution of the random variable that (presumably) generated the observations. When evaluated on the actual data points, it becomes a function solely of the model parameters. In maximum likelihood estimation, the argument that maximizes the likelihood function serves as a point estimate for the unknown parameter, while the Fisher information (often approximated by the likelihood's Hessian matrix at the maximum) gives an indication of the estimate's precision. In contrast, in Bayesian statistics, the estimate of interest is the ''converse'' of the likelihood, the so-called posterior probability of the parameter given the observed data, which is calculated via Bayes' rule. Definition The likelihood function, para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patient
A patient is any recipient of health care services that are performed by Health professional, healthcare professionals. The patient is most often Disease, ill or Major trauma, injured and in need of therapy, treatment by a physician, nurse, optometrist, dentist, veterinarian, or other health care provider. Etymology The word wikt:patient, patient originally meant 'one who suffers'. This English noun comes from the Latin word , the present participle of the deponent verb, , meaning , and akin to the Ancient Greek, Greek verb ( ) and its cognate noun (). This language has been construed as meaning that the role of patients is to passively accept and tolerate the suffering and treatments prescribed by the healthcare providers, without engaging in Shared decision-making in medicine, shared decision-making about their care. Outpatients and inpatients An outpatient (or out-patient) is a patient who attends an Outpatient clinic (hospital department), outpatient clinic with no ...

Death
Death is the end of life; the irreversible cessation of all biological functions that sustain a living organism. Death eventually and inevitably occurs in all organisms. The remains of a former organism normally begin to decompose shortly after death. Some organisms, such as '' Turritopsis dohrnii'', are biologically immortal; however, they can still die from means other than aging. Death is generally applied to whole organisms; the equivalent for individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said ''to die'', as a virus is not considered alive in the first place. As of the early 21st century, 56 million people die per year. The most common reason is aging, followed by cardiovascular disease, which is a disease that affects the heart or blood vessels. As of 2022, an estimated total of almost 110 billion humans have died, or rou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Case Mix Index
Case mix index (CMI) within health care and medicine, is a relative value assigned to a diagnosis-related group of patients in a medical care environment. The CMI value is used in determining the allocation of resources to care for and/or treat the patients in the group. Resource Use Groups Patients are classified into groups having the same condition (based on main and secondary diagnosis, procedures, age), complexity (comorbidity) and needs. These groups are known as Diagnosis Related Groups (DRG), or Resource Use Groups (RUG). Each DRG has a relative average value assigned to it that indicates the amount of resources required to treat patients in the group, as compared to all the other diagnosis-related groups within the system. The relative average value assigned to each group is its CMI. Hospital CMI The CMI of a hospital reflects the diversity, clinical complexity and the needs for resources in the population of all the patients in the hospital. The CMI value of a hos ...

Diagnosis Codes
In health care, diagnosis codes are used as a tool to group and identify diseases, disorders, symptoms, poisonings, adverse effects of drugs and chemicals, injuries and other reasons for patient encounters. Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification. In medical classification, diagnosis codes are used as part of the clinical coding process alongside intervention codes. Both diagnosis and intervention codes are assigned by a health professional trained in medical classification such as a clinical coder or Health Information Manager. Several diagnosis classification systems have been implemented to various degrees of success across the world. The various classifications have a focus towards a particular patient encounter type such as emergency, inpatient, outpatient, mental health as well as surgical care.

Severity Of Illness
Severity of illness (SOI) is defined as the extent of organ system derangement or physiologic decompensation for a patient. It gives a medical classification into minor, moderate, major, and extreme. The SOI class is meant to provide a basis for evaluating hospital resource use or to establish patient care guidelines. Patients are assigned their SOI based on their specific diagnoses and procedures performed during their medical encounter, which is generally an inpatient hospital stay. Patients with higher SOI (e.g. major or extreme) are more likely to consume greater healthcare resources and stay longer in hospitals than patients with lower SOI in the same diagnosis-related group (DRG). The Centers for Medicare and Medicaid Services considered the 3M APR-DRG and SOI system as a potential evolution to the DRG system in 2006, but received such negative feedback from the industry that in March 2007 decided to adopt another internally developed system evolved from the DRG. SOI is still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Terminology
Medical terminology is a language used to precisely describe the human body including all its components, processes, conditions affecting it, and procedures performed upon it. Medical terminology is used in the field of medicine. Medical terminology has quite regular morphology, the same prefixes and suffixes are used to add meanings to different roots. The root of a term often refers to an organ, tissue, or condition. For example, in the disorder known as hypertension, the prefix "hyper-" means "high" or "over", and the root word "tension" refers to pressure, so the word "hypertension" refers to abnormally high blood pressure. The roots, prefixes and suffixes are often derived from Greek or Latin, and often quite dissimilar from their English-language variants. This regular morphology means that once a reasonable number of morphemes are learnt it becomes easy to understand very precise terms assembled from these morphemes. Much medical language is anatomical terminology, conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Manuals
Medicine is the science and practice of caring for patients, 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. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of creativity and skill), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
