Premature babes are considered a vulnerable population. They are at hazard for many complications of prematureness such as anaemia. hypoglycaemia. Cerebral Palsy. retinopathy. and necrotizing enterocolitis ( Mayo Clinic. 2014 ) . Necrotizing enterocolitis ( NEC ) is a annihilating status that occurs in the premature baby’s intestine in which the cells run alonging the intestine wall are injured ( 2014 ) . This hurt can happen in premature babes after they start feeding. The infant mortality rate for NEC is 12. 5 of 100. 000 unrecorded births ( Fitzgibbons. et Al. 2009 ) . This paper will specify epidemiology and depict the epidemiological trigon as it relates to NEC. Types of epidemiology will besides be discussed. cultural considerations of vulnerable populations such as African Americans. and assorted degrees of bar of NEC will be examined. Necrotizing enterocolitis is a annihilating inflammatory intestine disease of the newborn chiefly impacting premature babes ( Gibbons. et Al. . 2008 ) .
This disease is characterized by ischaemic mortification of the liner of the bowels. Premature babes are at peculiar hazard of developing NEC. and the focal point is on cut downing exposure to put on the line factors and implementing intercessions that will forestall the upset such as human milk eating and the turning away of hypertonic expressions ( 2008 ) . Epidemiology is the chief scientific discipline of public wellness and is portrayed as an gathering of fortes with a common end: optimum wellness for the whole community ( Stanhope & A ; Lancaster. 2008 ) . Epidemiologists strive to happen the root of diseases and why they affect certain populations. These causes allow public wellness representatives to measure and measure upsets. place vulnerable populations. program for alterations in intervention. implement evidence-based pattern. and evaluate results for better wellness of vulnerable populations. There are many stairss and methods involved in epidemiology such as surveillance. randomized studies. experimental surveies. and cohort surveies ( Stanhope & A ; Lancaster. 2008 ) . Epidemiologists rely on scientific methods. experience. adept judgement. and exceeding cognition of specific populations or communities in order to follow disease waies.
Common stairss in the epidemiologic attack include executing an initial observation to corroborate outbreaks. disease definition. disease description by clip. topographic point. individual. the creative activity of a hypothesis. the conductivity of analytical surveies. the summarisation of findings. and recommendations ( 2008 ) . In footings of methods related to epidemiology. one of the first issues to turn to in any epidemiologic survey is how to obtain the information. There are three major classs of informations beginnings including routinely collected informations such as nose count informations and critical records. informations collected for other intents such as medical and insurance. and original informations collected for specific surveies ( Stanhope & A ; Lancaster. 2012 ) . One method that is used rather often by epidemiologists is the morbidity study which collects informations on the wellness position of a population group. Purposes of morbidity studies are to find the frequence of chronic and acute diseases and disablement. cod measurings of bodily features. carry on physical scrutinies and lab trials. and probe other wellness related features of specific concern to those who sponsor the study ( Friss & A ; Sellers. 2009 ) . The CDC studies 342 deceases per twelvemonth of necrotizing enterocolitis the neonate ( CDC. 2013 ) .
Epidemiologists analyzing the incidence of NEC might utilize a population-based study to place instances of NEC such as the one done in upstate New York in 2002. A study was done in a chiseled. six county perinatal country. The intent of the survey was to depict the birthweight. gender. and race specific incidence every bit good as any demographic and clinical correlatives in a population of babies born during an eight-year period ( Llanos. et Al. . 2002 ) . The research workers received their informations by reexamining all the medical records for babies discharged with a diagnosing of NEC. the figure of lives births. gestational age of the neonates. birth weight. age at diagnosing of NEC. sex of newborn. and maternal race/ethnicity ( 2002 ) . By roll uping this medical information. the epidemiologists were able to make their hypothesis. sum up their determination. and do their recommendations based on findings. In the instance of the Llanos. et Al. . 2002 survey. the research workers were able to find the highest incidence of NEC was among babies born less than 2500 gms and there is a direct association of the development of NEC and the start of enteric eatings.
Gestational age at the clip of provenders played a factor every bit good as the sort of milk the babies are being fed. with chest milk take downing the incidence of NEC ( Llanos. et Al. . 2002 ) . The three elements of the epidemiology trigon are the agent. host and the environment. A person’s hazard for disease can be increased or decreased by altering one of the elements on this trigon ( Stanhope & A ; Lancaster. 2012 ) . The agent is the component that causes the disease. While the pathophysiology of NEC remains ill-defined. grounds points to prematureness and familial sensitivity as causative agents ( Maheshwari. et Al. 2011 ) . Prematurity and immatureness of the GI piece of land are the most of import forecasters for developing NEC. The host is the premature babe and the environment is the immature GI piece of land. The occupation of the epidemiologist is to seek to interrupt one of the sides of the epidemiology trigon which disrupts the connexion between the environment. the host. and the agent ; therefore halting the prolongation of the disease. In the instance of NEC. the focal point is more on bar through intercessions such as presenting unreal milk through enteric eatings to the immature GI piece of land ( 2011 ) .
Although NEC can happen in babies who have ne’er been fed. 95 % of instances occur in babies with a history of enteric eatings ( 2011 ) . Babies fed unreal expressions as opposed to having human milk are at a higher hazard of developing NEC due to the deficiency of substances such as immunoprotective factors and anti-microbials ( 2011 ) . Premature babes are really vulnerable to undertaking necrotizing enterocolitis with low birth weight being the most of import hazard factor ( Fitzgibbons. et Al. . 2009 ) . Because of promotion in the attention of premature newborns. more low-birth weight premature babes are lasting under the attention of a Neonatal Intensive Care Unit. Compared with term babies. premature newborns have increased intestine mucosal permeableness which increases their exposure to developing NEC ( Maheshwari. et Al. . 2011 ) . Preterm babies normally have a patent ductus arteriosus ( PDA ) with its characteristic left-to-right shunt. decreasing blood flow to the intestine mucous membrane ( 2011 ) . In add-on. female parents who choose non to suckle are seting their pre-term baby at increased hazard of developing NEC. Human milk contains constituents that help maturate the intestine of neonates.
The GI system plays a major function in functioning as a barrier to pathogens and allergens and as an instrument for alimentary soaking up ( Walker. 2011 ) . Artificially fed babies do non have human milk elements that foster the closing of the tight junctions between cells. increasing the newborn’s hazard of developing NEC. Necrotizing enterocolitis baby mortality rates are highest among black adult females ( Holman. et Al. . 1997 ) . Black adult females are more likely to give birth to premature babes. and they have the lowest rates of sole breastfeeding ( 1997 ) . Healthcare suppliers are cognizant of the importance of feeding all babies but peculiarly premature babies human milk. All female parents are educated about optimum eating patterns. but the concluding determination is up to the female parent. At the really least. if a female parent chooses non to suckle or pump her milk for her babe. she should be offered donor milk. Many healthcare suppliers are torn between honouring the picks of the female parent and supplying optimum attention to the baby. If all babies were given donor human milk. the decease rate from NEC could be significantly decreased.
Healthcare suppliers must weigh the ethical hazards of disgracing the mother’s wishes over the overall wellbeing of their vulnerable patient. When reding the new female parent about optimum eating patterns for the premature babe. evidence-based pattern must be considered and taught to the female parent. Clinical surveies show a protective consequence of human milk provenders against NEC when compared to infant expression ( Maheswari. 2011 ) . These protective effects have been proven to be retained in donor milk every bit good ( 2011 ) . For this ground. the usage of human milk or donor human milk should be strongly encouraged in all premature babies. The three degrees of bar. primary. secondary. and third supply a model used in public wellness nursing ( Stanhope & A ; Lancaster. 2012 ) .
The end of primary bar is to supply intercessions that help to forestall the happening of disease. In the instance of necrotizing enterocolitis. bar should get down during gestation by supplying entree to early prenatal attention. detaining preterm labour when possible. and the turning away of unreal baby expressions in the preterm neonate. Secondary bars incorporates intercessions designed to increase the chance that a individual with a disease will hold that status diagnosed at a phase when intervention is likely to ensue in a remedy ( Stanhope & A ; Lancaster. 2008 ) . “Health showings are the pillar of secondary prevention” ( 2008 ) .
An illustration of secondary bar in relation to NEC would be slow provenders. monitoring for feeding intolerance. and the usage of contraceptive antibiotics ( Gibbons. et Al. . 2008 ) . Third bar is aimed at restricting disablement from disease and normally occur in the infirmary scene. Premature neonates are already hospitalized so if they do acquire to the primary degree of bar. the most likely need a higher degree of attention such as cannulation. surgery. volume replacing. antibiotics. TPN. and trouble control ( Gibbons. et Al. . 2008 ) .
Epidemiology is the nucleus of public wellness and has reformed disease bar and wellness publicity significantly over the old ages. go oning to happen new disease tendencies and preventative steps. NEC is a annihilating disease that has a high mortality rate among premature neonates. By seeking to interrupt one of the weaponries in the epidemiology trigon and concentrating on the three degrees of bar. public wellness workers and neonatologists can guarantee positive results for premature babes.
