bundled paymentA single comprehensive payment made to healthcare providers—hospitals and physicians—for a group of related services, based on the expected costs for a clinically defined episode of care.
case rateInfectious disease The number of cases of a particular infection or exposure during a unit of time, divided by the population during that period; CRs are often expressed in terms of a population of 100,000
rate(rat) [L. rata, calculated]
The speed or frequency of occurrence of an event, usually expressed with respect to time or some other known standard.
In radiology, the speed with which medical images are recorded, usually expressed in images per second.
The rate of occurrence of new cases of a disease.
basal metabolic rateAbbreviation: BMR
The metabolic rate as measured 12 hr after eating, after a restful sleep, with no exercise or activity preceding testing, with elimination of emotional excitement, and at a comfortable temperature. It is usually expressed in terms of kilocalories per square meter of body surface per hour. It increases, for example, in hyperthyroidism. Synonym: resting energy expenditure
baseline fetal heart rateAbbreviation: FHR
The average range of beats per minute recorded within a 10-min time frame. The normal range is between 120 and 160 beats per minute.
The number of live births per 1000 in the population in a given year.
case rateMorbidity rate.
case fatality rate
The percentage of individuals afflicted with an illness who die as a result of it.
The frequency with which a gene will be inherited or expressed by identical or fraternal twins.
The number of deaths in a specified population, usually expressed per 100,000 population over a given period, usually 1 year. Synonym: death-to-case ratio; mortality rate
In assisted reproduction technology, the number of newborn deliveries achieved in every one hundred follicular aspirations, embryo transfers, or stimulated cycles.
The quantity of medicine or radiation administered per unit of time.
erythrocyte sedimentation rateAbbreviation: ESR
See: sedimentation rate
The rate of occurrence of negative test results in those who have the attribute or disease for which they are being tested.
The rate of occurrence of positive test results in those who do not have the attribute or disease for which they are being tested.
The number of births per year per 1000 women between ages 15 and 44 in a given population.
fetal mortality rate
The number of fetal deaths per 1000 live births, usually per year.
The rate at which an individual, tissue, or organ grows over time.
heart rateAbbreviation: HR
The number of heartbeats per unit of time, usually expressed or written as number per minute. A normal resting heart rate for an adult is 60–100 beats per minute.
infant mortality rate
The number of deaths per year of live-born infants less than 1 year of age divided by the number of live births in the same year. This value is usually expressed as deaths per 100,000 live births.See: neonatal mortality rate; perinatal mortality rate
The speed of administration of a solution in mL/hr.
CAUTION!It is calculated by the following formula: Rate = (Dose × 60 × Body weight)/Concentration, in which the dose is in mcg/kg/min; 60 is in min/hr; weight is in kg; and the concentration of the substance in solution is in mcg/mL.
maternal mortality rate
The number of maternal deaths in 1 year from puerperal causes (such as those associated with pregnancy, childbirth, and the puerperium) within 42 days after delivery divided by the number of live births in that same year. This value is usually expressed as deaths per 100,000 live births. See: illustration
maximum midexpiratory flow rateAbbreviation: MMFR
The average airflow during the middle half of a forced vital capacity effort.
The rate of utilization of energy. This is usually measured at a time when the subject is completely at rest and in a fasting state. Energy used is calculated from the amount of oxygen used during the test.See: basal metabolic rate; basal metabolism
The number of cases per year of certain diseases in relation to the size of the population in which they occur. Synonym: case rate
mortality rateDeath rate.
neonatal mortality rate
The number of deaths in 1 year of infants aged 0 to 28 days divided by the number of live births in that same year.See: maternal mortality rate; perinatal mortality rate
peak expiratory flow rate
The maximum rate of exhalation during a forced expiration, measured in liters per second or liters per minute. It is used as a test of airway obstruction.
perinatal mortality rate
The number of stillbirths (in which the gestation period was 28 weeks or more) in the first 7 days of life divided by the number of live births plus stillbirths in the same year. This value is usually expressed as deaths per 100,000 live births plus stillbirths.See: infant mortality rate; neonatal mortality rate
periodontal disease rateSee: periodontal (Ramfjord) index
The number of heartbeats per unit of time that can be detected by palpating any accessible artery.
The number of breaths per unit of time.
sedimentation rateAbbreviation: ESR (erythrocyte sedimentation rate)
A nonspecific laboratory test used as a marker of inflammation. In this test the speed at which erythrocytes settle out of unclotted blood is measured. Blood to which an anticoagulant has been added is placed in a long, narrow tube, and the distance the red cells fall in 1 hr is the ESR. Normally it is less than 10 mm/hr in men and slightly higher in women.
The speed at which the cells settle depends on how many red blood cells clump together. Clumping is increased by the presence of acute-phase proteins released during inflammation.
specific absorption rate
The rate at which electromagnetic energy is absorbed by a kilogram of tissue, usually expressed as the heat absorbed by the tissue, or as the power absorbed per unit of mass.
ventilation rateAbbreviation: VR
The number of breaths per minute.
