Factors associated with nosocomial fungal sepsis among patients in the paediatric intensive care unit at the Chris Hani Baragwanath academic hospital

Ahn, Seung-Hye January 2017 (has links)
A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg in partial fulfillment of the requirements for the degree of Master of Medicine in the branch of Paediatrics and Child Health 29 May 2017 / Introduction Sepsis, and in particular, severe sepsis, remains a major cause of death in children worldwide. One of the areas where the burden of sepsis is keenly felt is in the paediatric intensive care unit (PICU) setting, contributing significantly to childhood mortality. Fungal organisms have emerged as a major organism contributing to nosocomial sepsis in PICU. No local data regarding nosocomial fungal sepsis in the non-neonatal, PICU population exists regarding this matter. This study describes the characteristics of patients with nosocomial fungal sepsis in the PICU at South Africa’s largest hospital Chris Hani Baragwanath Academic Hospital (CHBAH). Methods This study was a retrospective review of patient records. All patients aged 0-16 years admitted to the PICU at Chris Hani Baragwanath Academic Hospital (CHBAH) from January 2008 through December 2011 were assessed. A total of seventeen patients who developed nosocomial fungal sepsis were included in this study. Results The incidence of candidaemia was reported to be 3.2 per 100 cases. The major age group affected by nosocomial fungal sepsis was the under one age group. The most common diagnoses on admission were lower respiratory tract infection (LRTI) followed by haematology-oncology and acute gastroenteritis cases. ICU factors found to commonly co-­‐exist with proven nosocomial fungal sepsis were presence of a central venous catheter (100%), mechanical ventilation (82%), arterial line (70%), and systemic corticosteroid use (47%). The penicillin class was the most common antimicrobial that patients were found to be on at the time of nosocomial sepsis. The most common fungal organism as a cause for nosocomial sepsis was C. parapsilosis rather than C. albicans. Furthermore, the majority of this study’s isolates were susceptible to voriconazole rather the current empiric antifungal of choice, namely fluconazole. Conclusion The presence of central venous catheters, arterial lines, mechanical ventilation and systemic corticosteroid use is common in paediatric patients with nosocomial fungal sepsis. However, this study was unable to determine statistically significant factors associated with fungal sepsis in a tertiary PICU due to the surprisingly small number of cases (n=35) detected over a four-year period. This perhaps represents the most striking finding of the study together with a concerning pattern of fluconazole resistance (14%) among isolated organisms. / MT2017

Surrogate decision making for the critically ill intensive care unit patient

Suurdt, Jeanette 25 April 2008 (has links)
The technological complexity of the ICU is often focused on saving lives however, it is frequently a place to support the dying. Because of the serious nature of critical illness, patients are unable to communicate their wishes, values and views. Family members are often called upon to communicate the critically ill patients’ wishes and many report feeling burdened with the task. The distress described may lead to difficulty mobilizing coping mechanisms and may affect their ability to make appropriate decisions for their family member’s care. Hence, an in depth understanding of the surrogate’s experience is critical to plan effective interventions and provide anticipatory guidance to support the process of making decisions around end of life care. Objective The purpose of the study is to describe the surrogate decision makers’ appraisals of the demands of decision making for a critically ill adult intensive care unit patient and the coping strategies employed by them during this experience. Method A descriptive study design using a qualitative interviewing approach extracted perceived stressors and coping strategies using systematic, focused thematic analysis guided by Folkman and Lazarus’ Stress and Coping Paradigm. Findings Respondents appraisals identified the following perceived stressors: doubt of self efficacy, unknowns, impingement of real life, and problematic relay of information. The surrogates’ perception of their ability to manage the decision making process required their awareness of the decision making role and magnitude of illness, their need to form partnerships, time to reflect on prior discussions and experience, and their appraisal of the patients’ suffering. Participants described emotion and problem based coping strategies they employed during the task. To emotionally justify their decisions, surrogates’ referred to their understanding of patient wishes and sought solace and comfort from the health care staff. In addition, surrogates used strategies to solve problems encountered including dealing with others, employing strategies to decrease their uncertainty and mobilizing time to process the events unfolding. Conclusions End of life decisions in the intensive care are complex and demanding. A better understanding of the process may guide health care professionals in developing focused interventions to assist surrogates through a painful process. / Thesis (Master, Nursing) -- Queen's University, 2008-04-25 09:29:27.1

Stress experienced by parents from the neonatal intensive care unit

Steedman, Wendy Kate January 2007 (has links)
The psychometric properties of this Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU) were assessed, before using the scale to describe stress experienced by parents in a Neonatal Intensive Care Unit (NICU). The extent to which parental stress from the parent-infant relationship in the unit was linked to parenting they received as a child, and adjustment to their couple relationship, was also examined. The sample consisted of 182 mothers and 183 fathers, who were in a cohabitating relationship, of infants from the NICU at Christchurch Women's Hospital. The self-report questionnaires included the PSS:NICU, Parental Bonding Instrument, and the Dyadic Adjustment Scale, and were administered to parents within 2-3 weeks of their infant's birth. This study extends the finding of satisfactory psychometric properties of the PSS:NICU (Franck, Cox, Allen & Winter, 2005; Miles, Funk & Carlson, 1993; Reid & Bramwell, 2003) to this New Zealand sample. Mothers experienced significantly higher stress from the unit compared to fathers (p < .01). A previous finding, for mothers, of the parent-infant relationship being the most stressful aspect of the unit (Franck et al., 2005; Reid & Bramwell, 2003; Shields-Poe & Pinelli, 1997) extends to the New Zealand sample. The most stressful aspect of the unit for fathers was sights and sounds. Lack of evidence was found for associations between parental stress from the parent-infant relationship in the unit and parenting received as a child, or adjustment to their couple relationship. A weak but significant negative correlation was, however, found between stress from the mother-infant relationship and maternal care received in childhood. It is unnecessary to provide all parents with intervention further to what is already being practiced in the unit, as overall low levels of stress were reported. Some parents, however, did find the unit more stressful, and they may benefit from increased intervention.

Buscando a assistência humanizada : percepção do acompanhante em unidade de terapia intensiva /

Israel, Fernanda de Cássia. January 2008 (has links)
Resumo: A humanização é vista como um conjunto complexo de atitudes e ações motivadas por pensamentos éticos, humanísticos, sociais e holísticos. Hoje, a proposta de humanização em UTI tem um horizonte mais amplo, englobando desde o ambiente físico até as relações entre as equipes de saúde. Dessa forma, valorizar a presença de acompanhantes na instituição hospitalar e apreender sua percepção é um processo fundamental para o alcance de uma prática assistencial realmente humanizada. Assim, esse estudo tem o objetivo de analisar a percepção do acompanhante de pacientes que estão em processo de hospitalização, na busca da assistência humanizada em Unidade de Terapia Intensiva. É uma pesquisa de abordagem qualitativa, sendo entrevistados os acompanhantes nas UTIs pediátrica e coronariana do HC da Faculdade de Medicina de Botucatu - UNESP. Os depoimentos foram analisados através da Técnica de Análise de Conteúdo proposta por Bardin (96). As categorias identificadas foram: acolhimento e ambiente da UTI: estrutura física e profissionais de saúde. As percepções dos familiares em ser acompanhante refletem uma não diferenciação em ser acompanhante e ser visitante, porém enfatizam que a presença da família, mesmo nos horários de visitas, auxilia na recuperação do paciente, como também os tranqüilizam. Os acompanhantes consideram as informações fornecidas pelos profissionais de saúde, adequadas e verdadeiras. O atendimento das unidades é percebido como satisfatório, porém revelam ser necessário um repensar sobre as normas e rotinas das unidades, principalmente em relação aos horários de visitas. A percepção sobre acomodação reflete a possibilidade de estar próximo ao paciente, porém revelam a dificuldade por não ter um local apropriado para se acomodar que se localize próximo a UTI.

Today, the proposal of humanization at ICUs has a broader horizon which includes the physical environment as well as relations between health care teams. Hence, valuing the presence of companions in hospitals and apprehending their perceptions is a fundamental process for accomplishing an actually humanized care provision practice. Therefore, this study aimed at analyzing the perceptions of companions of patients undergoing the hospitalization process in the search for humanized care at an Intensive Care Unit. It is a qualitative study in which companions of patients hospitalized at the pediatric and coronary ICUs of the Botucatu School of Medicine University Hospital - UNESP were interviewed. The reports were analyzed through the Content Analysis Technique proposed by Bardin (96). The identified categories were: patient reception and the ICU enviroment - physical structure and health care professionals. Family members' perceptions of being companions reflected a non-differentiation between being a companion and being a visitor; however, they emphasized that the presence of relatives, even if only at visiting hours, helped patients' recovery as well as made them calm. Companions considered the information provided by health care professionals to be adequate and truthful. The care given at the units was perceived as satisfactory although the respondents reported the need to reconsider the units' rules and routine, especially as concerns visiting hours. The perception concerning acommodation reflected the possibility of being close to the patient; however, they revealed the difficulty of not having an appropriate accomodation area near the ICU. They also perceived that the University Hospital...

Terminalidade em UTI PediÃtrica e Neonatal: prÃticas mÃdicas que antecedem o Ãbito em um hospital de referÃncia do Nordeste Brasileiro / End-of-Life in Pediatric e Neonatal Intensive Care Unit: medical practices before death in a reference Pediatric hospital at Brazilin Northeast

NeulÃnio Francisco de Oliveira 26 September 2011 (has links)
nÃo hà / MudanÃas que aconteceram no sÃculo XX, permitiram que avanÃos tecnolÃgicos aumentassem a sobrevida diante de doenÃas anteriormente incurÃveis e processos patolÃgicos irreversÃveis. No entanto, a busca incessante pela cura, alÃm de levar ao aumento da sobrevida, tambÃm gerou a obstinaÃÃo terapÃutica, ou seja, medidas terapÃuticas fÃteis diante de evoluÃÃo inexorÃvel para a morte, impactando em indicadores como Ãndice de satisfaÃÃo do cliente e cuidadores, tempo mÃdio de permanÃncia, elevaÃÃo de custos, bem como em prejuÃzo na distribuiÃÃo equitativa de recursos. No inÃcio dos anos 90, a limitaÃÃo do suporte de vida (LSV) comeÃou a ser estudada e considerada, em paÃses da Europa, Estados Unidos, Canadà e Austrlia, como forma de assistir os pacientes nesses casos, uma vez que as medidas terapÃuticas nÃo mais trariam benefÃcios, mas gerariam prolongamento do sofrimento e do processo de morrer. No Brasil, contudo, os estudos sÃo limitados e os dados referentes ao Nordeste do paÃs sÃo ainda muito escassos. O objetivo do estudo foi caracterizar as condutas mÃdicas que antecederam o Ãbito de pacientes em UTI pediÃtrica e neonatal em um hospital de referÃncia do Nordeste Brasileiro. Foram estudados 86 prontuÃrios de pacientes que morreram nas referidas UTIs no perÃodo de dezembro/09 a novembro/10. Apenas 3,5% dos Ãbitos ocorreram apÃs LSV registrada em prontuÃrio, destes 33,7% tinham doenÃa crÃnica associada, sendo as neoplasias as mais comuns. As causas de Ãbito mais comuns foram sepse (23,5%), falÃncia de mÃltiplos ÃrgÃos (18,8%), insuficiÃncia respiratÃria (12,9%), cardiopatias congÃnitas (8,2%) e as outras causas somaram 36,6%. A maior parte dos pacientes morreu apÃs aumento das medidas de suporte avanÃado de vida, considerando as ultimas 24h antes do Ãbito: drogas vasoativas (59,3% 24h antes e 70,9% no momento do Ãbito); VentilaÃÃo mecÃnica (89,5% 24h antes e 95,2% no momento do Ãbito). Enquanto as medidas de cuidados e conforto nÃo tiveram a mesma expressÃo, tendo um aumento irrelevante: sedaÃÃo (39,5% 24h antes e 43% no momento do Ãbito); analgesia (60% 24h antes e 60,5% no momento do Ãbito). As manobras de ressuscitaÃÃo cardiopulmonar foram registradas em 4,7% 48h antes do Ãbito, 29,1% 24h antes e 69,4% no momento do Ãbito. O uso de adrenalina foi registrado em 55,4% antes do Ãbito. Conclui-se que a LSV ainda nÃo à frequentemente considerada como uma alternativa de assistÃncia de final de vida a pacientes pediÃtricos e neonatais no Estado do CearÃ, onde as condutas mais prevalentes incluem o incremento do suporte avanÃado de vida em detrimento das medidas de conforto e cuidados paliativos. Comparando-se com estudos do Sul e Sudeste do paÃs, evidencia-se uma grande diferenÃa, onde se observam uma maior prevalÃncia de LSV e cuidados paliativos para pacientes em fase terminal, o que denota prÃticas mais humanas e de maior qualidade na assistÃncia. / Changes around the world at the XX century allowed new technologies to improve the possibilities of surviving in so many cases of sickness that were incurable before. Besides the benefits it brought, other consequences have come together specially futility, in other words futile therapeutic measures when the cure is impossible and the death is inevitable. These facts have influence in client satisfaction, lengh of stay and costs elevation. Since 1990 life support limitation (LSL) started to be considered in Europe, United States, Canada and Austrlia to assist patients in terminal conditions to whom curative practices wouldnât bring any benefit. In Brazil there is a limited number of studies and the data from the Northeastern are even less. The aim of this study was to describe the medical practices before death in patients in PICU and NICU at a reference pediatric hospital in Brazilian Northeastern. Data were collected from 86 medical charts. Only 3.5% of LSL was registered. 33.7% of patients had some chronic disease and neoplasic ones were more comons. The main causes of death were: sepsis (23.5%), MDOS (18.8%), respiratory failure (12.9%), congenital heart disease (8.2%) and the other causes 36.6% together. Most of patients died after increment in vasoatives administration, considering the final 24 hours before death (59.3% 24h before, 70.9% at the momento of death). Mechanical ventilation (89.5% 24h before, 95.2% at the moment). In the other hand palliative care and pain control were not so frequent as could be expected: sedative (39.5 24h before, 43% at the moment) analgesic (60% 24h before, 60.5% at the moment). CPR was offered in 4.7% of patients 48h before death, 29.1% 24h before and 69.4% at the moment of death. Adrenaline was used in 55.4% at the moment of death. These data show that LSL is not a frequente alternative to assist terminal patients at PICU and NICU in Brazilian Northeastern, where more prevalent practices are to maintain life support instead of offer palliative care and pain control. At Southern and Southeastern practice include LSL and palliative care more frequently, what suggests better practices of the end-of-life care.

Plasma glutamine levels in critically ill intensive care patients / Arista Nienaber

Nienaber, Arista January 2015 (has links)
Background Nutritional treatment in the intensive care unit (ICU) has evolved from meeting nutritional requirements to manipulating patient outcome. Pharmaconutrition, referring to nutrients that are applied for their pharmacological properties, forms part of the standard nutritional care plan. The most abundant amino acid in the body, glutamine, is also the most-researched pharmaconutrient. It is an independent predictor of mortality in ICU patients, at both deficient and very high levels. Glutamine supplementation is recommended in the ICU setting for its proven outcome benefits. However, recent data showed that glutamine supplementation increases mortality risk in certain patient groups. Moreover, it suggested that not all ICU patients are glutamine deficient. Therefore, the main aim of this study was to investigate the plasma glutamine levels of adult ICU patients, on admission to the ICU. In addition, to elucidate the profile of ICU patients that can be expected to present with a glutamine deficiency or excess, with regards to gender, diagnosis and inflammatory markers. Methods In this observational, cross-sectional study, 60 mixed ICU adult patients admitted to two hospitals in the North West province were included in the study group. Blood sampling was conducted within 24 hours following ICU admission, to determine plasma glutamine, interleukin (IL)-6 and C-reactive protein (CRP) levels. Plasma glutamine levels were compared with those of a control group of healthy individuals, matched by age, race, and gender. Gender-related differences in plasma glutamine levels were investigated, as well as differences between patients with various medical conditions. The relationship between plasma glutamine levels and IL-6 or CRP was examined. Additionally, a CRP concentration cut-off point at which glutamine becomes deficient was determined by means of a receiver operating characteristic (ROC) curve. Results and discussion Intensive care unit patients had significantly lower plasma glutamine levels than healthy individuals on day one of ICU admission (p < 0.0001). However, only 38.3% (n = 23) had deficient plasma glutamine levels (< 420 μmol/L), while 6.7% (n = 4) presented with supra-normal levels (> 930 μmol/L). No significant difference could be detected between the plasma glutamine levels of male and female ICU patients (p = 0.116). Likewise, levels between diagnosis categories were also not significantly different (p = 0.325). There was a significant inverse association between plasma glutamine levels and CRP concentrations (r = -0.44, p < 0.05), and a trend towards an inverse association with IL-6 (r = - 0.23, p = 0.08). A CRP cut-off value of 95.5 mg/L was determined, above which plasma glutamine values became deficient; however, more research is needed to confirm this result. Conclusion and recommendations This research therefore showed that ICU patients, when compared with healthy individuals, had lower plasma glutamine levels on day one of admission to the ICU. However, not all were glutamine deficient, as the majority had normal and some presented with supra-normal plasma glutamine levels. An individualised approach should therefore be followed in identifying candidates for glutamine supplementation. The patients‟ condition alone may not be sufficient to predict glutamine status, but an association between plasma glutamine levels and CRP was firmly established, as well as a cut- off CRP-value above which glutamine can be expected to become deficient, which could be of use in this regard. / MSc (Dietetics), North-West University, Potchefstroom Campus, 2015
