Even though initiation of breastfeeding among term and preterm infants has increased, the incidence and duration among preterm infants continues to lag because of the unique challenges of breastfeeding preterm infants. African American mothers have the lowest rates of breastfeeding initiation and duration, and their preterm infants are less likely to receive breast milk while in the neonatal intensive care unit. The objective of this cross-€sectional quantitative study was to evaluate the relationship between breastfeeding and maternal sociodemographic factors as well as medical and obstetrical conditions for infants born between 32-€37 weeks gestational age in South Carolina from 2009 to 2011. The health belief model provided the framework for this study. Secondary data from the South Carolina Pregnancy Risk Assessment Monitoring System included 1,752 preterm pregnancies. Results of binary logistic regression and multivariate logistic regression analysis indicated that mothers who were African American and those who had lower income, no Medicaid, and lower education level breastfed less frequently. Findings may be used to decrease neonatal, postnatal, and infant morbidity and mortality, and to increase breastfeeding knowledge and support to ensure successful breastfeeding of preterm infants beyond the hospital.

Cleft lip with or without cleft palate (CLP) is an ongoing public health issue across the globe, and in the United States. The estimated number of babies born each year in the United States with cleft palate (CP) is about 2,650, while CLP affects approximately 4,440 babies. The purpose of this quantitative cross-sectional study was to determine if there is a relationship between CLP and maternal characteristics such as reproductive history (advanced maternal age, maternal obesity, prenatal visits, month prenatal care began, number of pregnancies, gestational age at birth, assisted reproductive technology used, gestational diabetes, and hypertension), socioeconomic status of the mother (marital status, education, mother's race, payment source for delivery, and place where birth occurred), and admission to the Neonatal Intensive Care Unit (NICU) in U.S. hospitals from January 2016 to December 2016. The epidemiological triad theory served as the study's framework. A secondary dataset from the National Vital Statistics System was used for this study. Logistic regression was used to test the hypothesized associations. Results indicated that many maternal characteristics such as mother's age (p = .000), maternal obesity (p = .020), number of prenatal visits (p = .001), total birth order (p = .001), gestational age at birth (p = .000), gestational diabetes (p = .002), and gestational hypertension (p = .032), mother's education (p = .000), marital status (p = .018), race (p = .000), and admission to NICU (p = .000) were significantly associated with CLP. Results of this study may help health care professionals identify the determinants of the risk of CLP so as to design and implement effective CLP preventive measures among United States populations that are disproportionately affected by this condition.

Purpose. To systematically develop and field test an intervention to engage families and healthcare teams in the decision-making process about life support for critically ill patients in the Intensive Care Unit (ICU). Setting. Adult medical-surgical ICU at a Canadian academic teaching hospital. Methods. The International Patient Decision Aid Standards (IPDAS) criteria and the Interprofessional Shared Decision Making (SDM) model guided the study of families facing decisions about life support for their relative in ICU that involved:1) systematic review; 2) qualitative descriptive study; 3) mixed methods field test of a novel patient decision aid (DA). Systematic review findings. Of 3162 citations, four trials evaluated interventions to improve communication between health professionals and patients/families. One intervention met eight of nine criteria for SDM but did not evaluate its effect on the benefit to communication. Qualitative study findings. Six family members and nine health professionals identified two options (life support or comfort care) and values associated with these options. Values included maintaining quality of life, surviving critical illness, minimizing pain and suffering, not being attached to machines, giving the family enough time to adapt emotionally to the patient’s health situation, and the judicious use of healthcare resources. Families were unlikely to become engaged without healthcare professionals making the decision explicit and minimizing other barriers across the decision-making process. Field test findings. Family members and health professionals for eight patients indicated that the DA was feasible to use, acceptable to users, had the potential to do what was intended, and did not seem to present adverse consequences to users. An enhanced delivery strategy is needed for future evaluation of its effect on facilitating patient/family involvement in decisions. Conclusions. Limited involvement of families in the process of decision-making about life support in the ICU reinforced the need for effective interventions to facilitate SDM. These studies validated the operationalization of the IPDAS criteria, as part of a systematic process for developing and field testing DAs. However, IPDAS criteria stop short of elements necessary to consider when implementing the DA in the processes of care.

Bakgrund: I en rapport från socialstyrelsen framgår det att akutmottagningarna runt omi landet har ca 2,5 miljoner patientfall, därtill kommer ännu fler anhöriga ochnärstående. Patientnämnden, som är det organ som hanterar klagomål från patienter ochanhöriga, uppger att det varje år kommer ungefär 4000 anmälningar där patienter ochanhöriga har känt sig kränkta och dåligt bemötta i sjukvården. Syfte: Syftet var attbeskriva hur vuxna anhöriga upplever bemötandet av sjuksköterskan vid akutasjukdomstillstånd inom somatisk vård. Metod: Arbetet skrevs som en allmänlitteraturstudie, enligt metod för kvalitativ manifestinnehållsanalys. Resultat:Anhörigas upplevelser i bemötandet från sjuksköterskorna kunde delas in i tre olikakategorier: trygghet-otrygghet, att bli sedd och bekräftad och sjuksköterskansmaktutövande. I det trygga och bekräftande bemötandet upplevde anhöriga känslor avtrygghet och betydelsefullhet, detta gav dem förutsättningar att skapa en handlingsplanför framtiden. När sjuksköterskan istället utövade sin maktställning upplevde anhörigakänslor av maktlöshet och att befinna sig i en beroendeställning. Detta gjorde attanhöriga fastnade i känslor av skuld och kunde inte ta sig vidare. / Background: A report from the National Board shows that emergency departmentsaround the country has about 2.5 million patient cases, which must be added even morefamily and friends. Patients Board, which is the body that handles complaints frompatients and relatives, said that each year, approximately 4000 notifications in whichpatients and families have felt insulted or badly treated in health care. Objective: Theaim was to describe how adult relatives are experiencing the hospitality of the nurse inacute illness in somatic care. Methods: This work was written as a general literaturestudy, by method of qualitative manifest content analysis. Results: Relatives'experiences of nurses' attitudes could be divided into three different categories:security-insecurity, to be seen and confirmed and nurses exercise of power. In the safeand confirmatory hospitality experienced relatives feelings of security and greatness,this gave them the ability to create an action plan for the future. When the nurse insteadexercised their position of power experienced relatives feelings of powerlessness andbeing in a position of dependence. This meant that families got stuck in feelings of guiltand could not get on.

This dissertation introduces a new problem in the delivery of healthcare, which could result in lower cost and a higher quality of medical care as compared to the current healthcare practice. In particular, a framework is developed for sedation and cardiopulmonary management for patients in the intensive care unit. A method is introduced to automatically detect pain and agitation in nonverbal patients, specifically in sedated patients in the intensive care unit, using their facial expressions. Furthermore, deterministic as well as probabilistic expert systems are developed to suggest the appropriate drug dose based on patient sedation level. This framework can be used to automatically control the level of sedation in the intensive care unit patients via a closed-loop control system. Specifically, video and other physiological variables of a patient can be constantly monitored by a computer and used as a feedback signal in a closed-loop control architecture. In addition, the expert system selects the appropriate drug dose based on the patient's sedation level. In clinical intensive care unit practice sedative/analgesic agents are titrated to achieve a specific level of sedation. The level of sedation is currently based on clinical scoring systems. In general, the goal of the clinician is to find the drug dose that maintains the patient at a sedation score corresponding to a moderately sedated state. This is typically done empirically, administering a drug dose that usually is in the effective range for most patients, observing the patient's response, and then adjusting the dose accordingly. However, the response of patients to any drug dose is a reflection of the pharmacokinetic and pharmacodynamic properties of the drug and the specific patient. In this research, we use pharmacokinetic and pharmacodynamic modeling to find an optimal drug dosing control policy to drive the patient to a desired sedation score.

Professional research project (Au.D.)--University of South Florida, 2003. / Title from PDF of title page. / Document formatted into pages; contains 20 pages. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: The purpose of this study was to determine the effects of an atypical pattern of early acoustic stimulation on auditory development. Previous human research suggests that the acoustic environment of pre-term human infants in the Neonatal Intensive Care Unit (NICU) negatively affects some aspects of auditory development. Animal research suggests that premature auditory stimulation interrupts auditory development. Because mice are born before their auditory systems are developed, they make an excellent model for research on fetal and postnatal plasticity of the auditory system. The premature auditory state of newborn mice is similar to that of the NICU pre-term infant, albeit, natural for mice C57 mouse pups were exposed to an augmented acoustic environment (AAE) of a nightly 12-hour regiment of 70 dB SPL noise burst, beginning before age 12 days (onset of hearing) and lasting for one month. / ABSTRACT: The prepulse inhibition (PPI) of mice exposed to the AAE was compared to that of non-exposed mice to observe short-term and long-term effects. Results showed that the prepulse inhibition of the AAE exposed mice did not differ significantly from that of the non-exposed mice. However, it is possible that the measurement used, PPI, may not have been appropriate or that the AAE may not have been an appropriate simulation of the NICU environment. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Rationnel : La pandémie de grippe A(H1N1)pdm09 a induit un grand nombre d’hospitalisation d’enfants en soins intensifs pédiatriques (SIP). L’objectif de cette étude a été de comparer l’incidence et la mortalité des enfants admis en SIP durant l’automne 2009 entre le Canada et la France, deux pays qui diffèrent essentiellement par l’immunisation de la population contre ce virus (première vague en été et taux de couverture vaccinale supérieur à 50% au Canada ; pas de vague estivale et couverture vaccinale de 18% en France). Méthodes : Nous avons comparé deux cohortes nationales qui ont inclue tous les patients avec une infection A(H1N1)pdm09 documentée, admis en SIP au Canada et en France entre le 1er Octobre 2009 et le 31 janvier 2010. Résultats : Au Canada, 160 enfants (incidence=2,63/100000 enfants) en 6 semaines ont été hospitalisés en SIP comparé aux 125 enfants (incidence=1,15/100000 enfants) en 11 semaines en France (p<0,001). Le taux de vaccination avant l’admission était inférieur à 25% parmi les enfants en situation critique dans les deux pays. La gravité à l’admission en SIP et le taux de mortalité ont été similaires au Canada et en France (4,4% en France vs 6,5% au Canada, p=0,45, respectivement). Au Canada, la vaccination contre le virus H1N1pdm09 a été associée avec une diminution du recours à la ventilation invasive (Odd Ratio 0.30, intervalle de confiance à 95% [0,11-0,83], p=0,02). Au Canada comparé à la France, les durées médianes de séjour en SIP et de ventilation invasive ont été plus courtes (2,9 vs 3 jours, p=0,03 et 4 vs 6 jours, p=0,02, respectivement). Conclusion : Les enfants canadiens et français critiquement malades ont été beaucoup moins nombreux à recevoir le vaccin contre le virus influenza A (H1N1)pdm09 en comparaison avec l’ensemble des enfants dans ces deux populations. Au Canada, où la couverture vaccinale a été élevée, le risque d’avoir une détresse respiratoire sévère était moins important parmi les enfants en situation critique ayant été vaccinés avant l’admission. / Background: The pandemic influenza A (H1N1)pdm09 resulted in a large number of admissions to pediatric intensive care units (PICUs). The objective of the study was to compare the incidence and mortality rate of children admitted to PICU in autumn 2009 between France and Canada, two countries that essentially differed by their population immunization to this virus (first pandemic wave in summer and vaccine coverage >50% in Canada; no wave in summer and vaccine coverage of 18% in France). Methods: We compared two national cohorts that included all patients with documented H1N1pdm09 infection, admitted to a PICU in Canada and in France between October 1st 2009 and January 31st 2010. Results: In Canada, 160 children (incidence=2.63/100,000 children) in 6 weeks were hospitalized in PICU compared to 125 children (incidence=1.15/100,000) in 11 weeks in France (p<0.001). Prior vaccination was under 25% among critically ill children in both countries. Severity of illness at PICU admission and mortality rates were similar in Canada and France (6.5%, vs 4.4 p=0.45, respectively). In Canada, H1N1pdm09 vaccination was associated with a decreased risk of requiring invasive ventilation (Odd Ratio 0.30, 95%Confidence Interval 0.11-0.83, p=0.02). In Canada as compared to France, median PICU length of stay and invasive ventilation durations were shorter (2.9 vs 3 days, p=0.03 and 4 vs 6 days, p=0.02, respectively). Conclusion: Critically ill Canadian and French children were much less likely to have received prior vaccination against influenza A (H1N1) pdm09 in comparison to all children in the populations. In Canada, where vaccination rate was higher, the risk of severe respiratory failure was less among those critically ill children receiving prior vaccination.

Rationnelle. La ventilation mécanique invasive (VI) s’accompagne lorsqu’elle se prolonge, d’une augmentation de la morbimortalité. Jusqu’à 64% des enfants hospitalisés aux soins intensifs sont ventilés et peu de données épidémiologiques existent afin d’estimer précocement la durée du support ventilatoire. Objectifs. Déterminer l’incidence et les facteurs de risque précoces de ventilation mécanique invasive prolongée aux soins intensifs pédiatriques. Méthode. Nous avons conduit une étude descriptive rétroélective sur un an. Tous les épisodes de VI aux soins intensifs du Centre hospitalier universitaire Sainte Justine de Montréal ont été inclus. Les facteurs de risque de VI prolongée (≥ 96 heures) ont été déterminés par régression logistique. Résultats. Parmi les 360 épisodes de VI, 36% ont duré ≥ 96 heures. Les facteurs de risques de ventilation prolongée en analyse multivariée sont : âge <12 mois, score de PRISM ≥ 15 à l’admission, pression moyenne dans les voies aériennes ≥13 cm H2O au jour 1 de ventilation, utilisation de la sédation intraveineuse continue au jour 1 de ventilation et ventilation non invasive avant intubation. Conclusion. La VI prolongée survient chez environ un tiers des patients ventilés. Les patients de moins de 12 mois semblent être plus à risque que les enfants plus âgés et devraient bénéficier de stratégies différentes pour diminuer leur durée de ventilation mécanique. La sévérité de la maladie, l’agressivité du support ventilatoire, l’utilisation d’une sédation continue au premier jour de ventilation sont également des facteurs à considérer dans les études visant à diminuer la durée de support ventilatoire. / Rationale. Invasive mechanical ventilation is associated, if prolonged, with higher morbidity and mortality. Up to 64% of children hospitalized in pediatric intensive care units (PICU) require invasive ventilation but little epidemiological data are available on children requiring prolonged acute invasive mechanical ventilation. Objectives. To determine the incidence rate and early risk factors for prolonged acute invasive mechanical ventilation in children. Methods. We conducted a retrolective longitudinal cohort study over a one-year period. All consecutive episodes of invasive mechanical ventilation in the PICU of Sainte-Justine Hospital were included. Risk factors for prolonged (≥ 96 hours) versus short (< 96 hours) ventilation were determined by logistic regression. Results. Among the 360 episodes of invasive ventilation, 36% had a length ≥ 96 hours. Following multivariate analysis, significant risk factors for prolonged acute invasive mechanical ventilation were: age <12 months, PRISM score ≥ 15 at admission, mean airway pressure ≥13 cm H2O on day one, use of continuous intravenous sedation on day one and use of non-invasive ventilation prior to intubation. Conclusion. Prolonged acute mechanical ventilation occurs in approximately one third of ventilated children. Younger children (aged <12 months) may be different from older patients and may require different strategies to decrease the duration of mechanical ventilation. Severity of illness, the aggressiveness of ventilatory support required and the use of continuous intravenous sedation on the first day of ventilation are also risk factors to consider in trials aimed at reducing mechanical ventilation duration.

It has already been established that the quality of life decreases after treatment in the intensive care unit. However, factors that have the strongest effect on the quality of life in ICU patients have not been identified. Information on post-ICU quality of life in long-term intensive care patients is particularly scarce. The findings of our research confirmed that long term treatment in the intensive care unit has major implications for the physical domains of health-related quality of life. The findings evidence that severity of illness on the first day in the ICU, number of therapeutic interventions upon ICU discharge and severe critical illness neuromuscular abnormalities are associated with impaired quality of life, while duration of mechanical ventilation is the factor with the strongest effect on reduced quality of life. Likewise, the findings demonstrate that usual systems for identification of severity of illness are not useful for predicting mortality in patients after discharge from the intensive care unit. Yet, identification of pre-ICU physical activity allows predicting post-ICU mortality.
