Northern Ireland Point Prevalence Survey of Hospital-acquired Infections and Antimicrobial Use 2012

The PHA�coordinated Northern Ireland's participation in ECDC's National Prevalence Survey on�Hospital-Acquired Infections & on Antimicrobial Use. Hospitals in Northern Ireland participated in data collection between May and June 2012.This report provides a snapshot of the levels of hospital-acquired infections (HAI) and levels of antimicrobial use (AMU) in hospitals in Northern Ireland during 2012.There have been three previous HAI PPS surveys and the last survey was carried out in 2006. It is difficult to compare each survey as the data was collected in a different way. However, after making allowances, there was an overall drop in HAI prevalence of 18% from 2006 to 2012.The PPS data collection was undertaken by hospital teams between May and June 2012 (one hospital deferred data collection until September 2012 because of a move to a new hospital); 16 hospitals surveyed 3,992 eligible patients. The median age of all patients was 66 years. A total of 383 (10 per cent) children under 16 years of age were surveyed.�Key results from this year's survey:The prevalence of HAI was 4.2%. A total of 166 patients were diagnosed with an active HAI with 3 patients having more than one infection.When comparing ward specialties, HAI prevalence was highest for patients in adult intensive care units (ICUs) at 9.1 per cent, followed by care of the elderly wards at 5.7%.The most common types of HCAI were respiratory infections (including pneumonia and infections of the lower respiratory tract) (27.9 per cent of all infections), surgical site infections (18.9 per cent) and urinary tract infections (UTI) (11.8 per cent).Since the last PPS in 2006 there has been a reduction in MRSA infections - from 0.9 per cent �of the hospital population to less than 0.1 per cent in patients; and a five-fold reduction in C. difficile infections (from 1.1 per cent to 0.2 per cent).The prevalence of antimicrobial use was 29.5%.Most antibiotic use (60 per cent) in hospitals was in patients receiving treatment for infections which commenced in the community. Eleven percent of surgical prophylaxis was prescribed for greater than one day.��

Expert clinical reasoning and pain assessment in mechanically ventilated patients: A descriptive study.

BACKGROUND: Pain assessment in mechanically ventilated patients is challenging, because nurses need to decode pain behaviour, interpret pain scores, and make appropriate decisions. This clinical reasoning process is inherent to advanced nursing practice, but is poorly understood. A better understanding of this process could contribute to improved pain assessment and management. OBJECTIVE: This study aimed to describe the indicators that influence expert nurses' clinical reasoning when assessing pain in critically ill nonverbal patients. METHODS: This descriptive observational study was conducted in the adult intensive care unit (ICU) of a tertiary referral hospital in Western Switzerland. A purposive sample of expert nurses, caring for nonverbal ventilated patients who received sedation and analgesia, were invited to participate in the study. Data were collected in "real life" using recorded think-aloud combined with direct non-participant observation and brief interviews. Data were analysed using deductive and inductive content analyses using a theoretical framework related to clinical reasoning and pain. RESULTS: Seven expert nurses with an average of 7.85 (±3.1) years of critical care experience participated in the study. The patients had respiratory distress (n=2), cardiac arrest (n=2), sub-arachnoid bleeding (n=1), and multi-trauma (n=2). A total of 1344 quotes in five categories were identified. Patients' physiological stability was the principal indicator for making decision in relation to pain management. Results also showed that it is a permanent challenge for nurses to discriminate situations requiring sedation from situations requiring analgesia. Expert nurses mainly used working knowledge and patterns to anticipate and prevent pain. CONCLUSIONS: Patient's clinical condition is important for making decision about pain in critically ill nonverbal patients. The concept of pain cannot be assessed in isolation and its assessment should take the patient's clinical stability and sedation into account. Further research is warranted to confirm these results.

Intuboidun hengityslaitehoitoa saavan aikuisen tehohoitopotilaan suunhoidon kirjaaminen

Tutkimuksen tarkoituksena oli tutkia potilastietojärjestelmien suunhoitosivut kaikilla suomalaisilla teho-osastoilla, joissa oli käytössä Clinisoft® -potilastietojärjestelmä ja, joilla hoidettiin intuboituja, hengityslaitehoitoa saavia aikuisia tehohoitopotilaita. Lisäksi tutkimuksessa analysoitiin yhden yliopistosairaalan teho-osaston hoitajien suunhoidon kirjauksia potilastietojärjestelmän vuorohuomioraporteista. Tutkimusosion 1 aineisto koostui aikuispotilaita hoitavien teho-osastojen (N=15) Clinisoft® -potilastietojärjestelmien suunhoitosivuista. Tutkimusosion 2 aineisto koostui yhden yliopistosairaalan teho-osaston intuboitujen, hengityslaitehoitoa saaneiden aikuisen tehohoitopotilaiden suunhoidon kirjauksista (n=97). Vuonna 2008–2009 hoidetuista intuboiduista, hengityslaitehoitoa saaneista tehohoitopotilaista (N=1180) valittiin satunnaisotannalla 100 potilasta, joiden suunhoitoon liittyvät potilasasiakirjat otettiin mukaan analyysiin. Aineistot analysoitiin sisällön erittelyllä. Suunhoitosivujen aihesisällöistä muodostettiin 14 sisältöluokkaa. Vuorohuomiokirjaukset oli kirjattu yleensä hengitys tai happeutuminen otsakkeiden alle, josta löytyi yhteensä 589 alkuperäislausumaa. Hoitajat kirjasivat ensin potilaan hengityslaitehoidosta ja happeutumisesta. Alkuperäislausumista tehohoitopotilaan suunhoitoon liittyviä lausumia oli 61 % (n=357). Vuorohuomiokirjauksista muodostettiin 11 sisältöluokkaa. Potilastietojärjestelmän suunhoitosivujen rakenne ei ohjannut VAP:a ehkäisevään suunhoitoon ja tehohoitopotilaan suunhoitoa kirjattiin usealle sivulle. Kaikkien tehohoito-osastojen suunhoitosivupohjissa oli kohdat suun kunnon arvioinnille ja suunhoidolle, mutta sivuilta ei aina selvinnyt tehohoito-osaston suunhoitoon käytättämiä välineitä. Sivuissa oli nähtävissä yksittäisiä VAP:n ehkäisyyn liittyviä interventioita. Vuorohuomioraportteihin kirjaaminen oli päällekkäistä suunhoitosivuun kirjattavien tietojen kanssa. Hoitajat kirjasivat tehohoitopotilaan hengityslaitehoidosta ja potilaan happeutumisesta. Suunhoidosta hoitajat kirjasivat eniten eritteiden määrää ja laatua ja vähiten suunhoidossa käytetyistä välineistä sekä suunhoitoon liittyvästä arvioinnista. Tehohoitopotilaan suuta hoidettiin keskimäärin 2.93 kertaa vuorokaudessa, eniten aamuvuoroissa. Suun kuntoa arvioitiin 1.12 kertaa vuorokaudessa. Pro gradu -tutkielma tuo uutta tietoa intuboidun, hengityslaitehoidossa olevan aikuisen tehohoitopotilaan näyttöön perustuvasta suunhoidosta, potilastietojärjestelmien suunhoitosivujen rakenteesta ja tehohoitopotilaan suunhoidon kirjaamisesta Suomessa. Tutkimustulosten ja kansainvälisten suositusten avulla kehitettiin Clinisoft® -potilastietojärjestelmän mallisivu tehohoitopotilaan suunhoidon tarpeen määrittämisen, suunnittelun, toteutuksen ja arvioinnin tueksi.

Diagnostic investigation of ventilator-associated pneumonia using bronchoalveolar lavage: comparative study with a postmortem lung biopsy

The purpose of the present study was to validate the quantitative culture and cellularity of bronchoalveolar lavage (BAL) for the diagnosis of ventilator-associated pneumonia (VAP). A prospective validation test trial was carried out between 1992 and 1997 in a general adult intensive care unit of a teaching hospital. Thirty-seven patients on mechanical ventilation with suspected VAP who died at most three days after a BAL diagnostic procedure were submitted to a postmortem lung biopsy. BAL effluent was submitted to Gram staining, quantitative culture and cellularity count. Postmortem lung tissue quantitative culture and histopathological findings were considered to be the gold standard exams for VAP diagnosis. According to these criteria, 20 patients (54%) were diagnosed as having VAP and 17 (46%) as not having the condition. Quantitative culture of BAL effluent showed 90% sensitivity (18/20), 94.1% specificity (16/17), 94.7% positive predictive value and 88.8% negative predictive value. Fever and leukocytosis were useless for VAP diagnosis. Gram staining of BAL effluent was negative in 94.1% of the patients without VAP (16/17). Regarding the total cellularity of BAL, a cut-off point of 400,000 cells/ml showed a specificity of 94.1% (16/17), and a cut-off point of 50% of BAL neutrophils showed a sensitivity of 90% (19/20). In conclusion, BAL quantitative culture, Gram staining and cellularity might be useful in the diagnostic investigation of VAP.

Desenlaces de las infecciones respiratorias en la unidad de cuidado intensivo de la fundación neumologica colombiana

Las infecciones asociadas a ventilación mecánica (VM) son frecuentes en la unidad de cuidado intensivo (UCI). Existen dos infecciones: neumonía (NAV) y traqueobronquitis (TAV). NAV genera impacto negativo en los desenlaces de los pacientes al aumentar la morbilidad, mortalidad y los tiempos en UCI y VM, pero no se conoce el impacto de TAV. El objetivo de este estudio fue identificar si hay diferencias entre NAV y TAV. Materiales y métodos: Se realizó un estudio de cohortes entre 2009 y 2013 en la UCI de la Fundación Neumológica Colombiana. De los pacientes con NAV y TAV se obtuvieron datos demográficos, epidemiológicos, microbiológicos y desenlaces como tiempos de estancia en UCI, VM y de hospitalización y mortalidad. Se compararon estadísticamente mediante t de Student y Chi2 para datos normales y prueba de Mann-Whitney para datos no normales. Resultados: Los pacientes con NAV y TAV fueron similares en la condición de ingreso a UCI. Al diagnóstico de la infección hubo diferencias significativas entre grupos en la oxigenación y tiempo de estancia hospitalaria, en UCI y VM. La microbiología fue con predominio de gérmenes Gram negativos y presencia de multirresistencia en el 52.5% de casos, sin diferencias significativas entre grupos. En los desenlaces, se observó diferencias en los tiempos totales de estancia en UCI, hospitalización y VM, pero sin diferencia en ellos después del diagnóstico. No hubo diferencias significativas en mortalidad. Conclusiones: NAV y TAV son similares en el impacto sobre la evolución de los pacientes en cuanto a morbilidad, estancias y mortalidad.

Aproximación a un modelo metodológico orientado a los procesos de gestión de conocimiento generadores de valor en organizaciones del sector salud en Colombia

En las organizaciones del sector salud en Colombia, se realizan procedimientos que a pesar de ser homólogos entre ellos, no se discriminan ocasionando que no siempre se escoja el que genere mejores resultados, no solo desde el punto de vista médico sino también de la dirección que se ejerce en las organizaciones la cual debe estar en función de optimizar cualquiera de los procesos propios de la actividad, en este caso, en busca de generación de valor usando como vía la apropiada GC, éste documento está orientado a demostrar que la GC aporta herramientas que permiten desarrollar la aproximación a un modelo metodológico que procura facilitar la elección de procedimientos en salud si se toman los costos asociados como criterios relevantes del análisis, se seleccionaron como instrumento de demostración a los procesos denominados Traqueostomía Quirúrgica y Traqueostomía Percutánea la intensión de desarrollar una aproximación a un modelo metodológico orientado a los procesos de gestión de conocimiento generadores de valor en organizaciones del sector salud en Colombia.

La familia del paciente en Unidad de Cuidado Intensivo (UCI)

Introducción: Ingresar a la UCI no es una experiencia exclusiva del paciente; implica e involucra directamente a la familia, en aspectos generadores de estrés, estrategias de afrontamiento, temores, actitudes y expectativas, la participación de la familia en el cuidado y el rol del psicólogo. Objetivo: Revisar de los antecedentes teóricos y empíricos sobre la experiencia de la familia en UCI. Metodología: Se revisaron 62 artículos indexados en bases de datos. Resultados: la UCI es algo desconocido tanto para el paciente como para la familia, por esto este entorno acentúa la aparición de síntomas ansiosos, depresivos y en algunos casos estrés post traumático. La muerte es uno de los principales temores que debe enfrentar la familia. Con el propósito de ajustarse a las demandas de la UCI, los familiares exhiben estrategias de afrontamiento enfocadas principalmente en la comunicación, el soporte espiritual y religioso y la toma de decisiones. El cuidado centrado en la familia permite una mejor comunicación, relación con el paciente y personal médico. El papel del psicólogo es poco explorado en el espacio de la UCI, pero este puede promover estrategias de prevención y de rehabilitación en el paciente y su grupo familiar. Discusión: es importante tener en cuenta que la muerte en UCI es una posibilidad, algunos síntomas como ansiedad, depresión pueden aparecer y mantenerse en el tiempo, centrar el cuidado en la familia permite tomar las decisiones basados en el diagnóstico y pronóstico y promueve expectativas realistas. Conclusiones: temores, expectativas, actitudes, estrategias de afrontamiento, factores generadores de estrés permiten explicar y comprender la experiencia de la familia del paciente en UCI.

Ressuscitação hipertônica com salina/dextran em pacientes sépticos graves estáveis : um estudo randomizado

Objetivo: estudar os efeitos hemodinâmicos da solução salina hipertônica/dextran, comparada com solução salina normal, em pacientes com sepse grave. Modelo: ensaio clínico randomizado, prospectivo, duplo-cego, controlado. Local: Unidade de Terapia Intensiva de um hospital universitário. Pacientes: 29 pacientes com sepse grave, admitidos na UTI com pressão de oclusão da artéria pulmonar (POAP) menor que 12 mmHg. Intervenções: os pacientes foram randomizados para receber 250 ml da solução salina normal [NaCl 0,9%] (Grupo SS, n=16) ou solução salina hipertônica [NaCl 7,5%]/dextran 70 8% ( Grupo SSH, n=13). Medidas e resultados: para cada grupo foram coletadas medidas hemodinâmicas, gasometrias (arterial e venosa), lactato e sódio séricos nos tempos 0, 30 minutos, 60 minutos, 120 minutos e 180 minutos. Durante o período do estudo não foi permitida qualquer alteração na infusão tanto de fluidos quanto das drogas vasopressoras. A POAP foi maior no grupo SSH, com a diferença sendo maior em 30 minutos (10,7±3,2 mmHg vs. 6,8±3,2 mmHg) e 60 minutos (10,3±3 mmHg vs. 7,4±2,9 mmHg); p<0,05. O índice cardíaco aumentou apenas no grupo SSH, sendo que as diferenças foram maiores em 30 minutos (6,5±4,7 l min-1 m-2 vs. 3,8±3,4 l min-1 m-2), em 60 minutos (4,9±4,5 l min-1 m-2 vs. 3,7±3,3 l min-1 m-2) e em 120 minutos (5,0±4,3 l min-1 m-2 vs. 4,1±3,4 l min-1 m-2); p<0,05. O índice sistólico seguiu o mesmo padrão e foi maior em 30 minutos (53,6[39,2-62,8] ml m-2 vs. 35,6[31,2-49,2] ml m-2) e em 60 minutos (46,8[39,7-56,6] ml m-2 vs. 33,9[32,2-47,7] ml m-2); p<0,05. A resistência vascular sistêmica diminuiu no grupo SSH e foi menor nos tempos 30 minutos (824±277 dyne s-1 cm-5 m-2 vs. 1139±245 dyne s-1 cm-5 m-2), em 60 minutos (921±256 dyne s-1 cm-5 m-2 vs. 1246±308 dyne s-1 cm-5 m-2) e em 120 minutos (925±226 dyne s-1 cm-5 m-2 vs. 1269±494 dyne s-1 cm-5 m-2); p<0,05. O sódio sérico aumentou no grupo SSH e foi maior do que o grupo SS em 30 minutos (145±3 mEq l-1 vs. 137±7 mEq l-1), em 60 minutos (143±4 mEq l-1 vs. 136±77 mEq l-1), em 120 minutos (142±5 mEq l-1vs. 136±7 mEq l-1) e em 180 minutos (142±5 mEq l-1 vs. 136±87 mEq l-1); p<0,05. Conclusão: Solução salina hipertônica/dextran pode melhorar a performance cardiovascular na ressuscitação de pacientes com sepse grave. Os efeitos hemodinâmicos parecem estar relacionados tanto ao efeito no volume quanto a melhora da função cardíaca. A SSH/dextran podem ajudar a restaurar rapidamente a estabilidade hemodinâmica em pacientes sépticos, hipovolêmicos, sem apresentar efeitos indesejáveis significativos.

Vivência do enfermeiro no cuidado humano na Unidade de Terapia Intensiva adulto

The purpose of the study was to understand the nurse s experience with human care in the Adult Intensive Care Unit (ICU). The objective was to describe the nurse s experience in caring for patients in the ICU and to analyze the nurse s perception of the care provided. The study is a descriptive inquiry of qualitative nature with a phenomenological approach. We interviewed eight nurses, 26 and 43 years of age, that provide care in the ICU of a private hospital in Natal/RN, during the manths of July and August of 2006. We analyzed the data acording to the method of Colaizzi. Four categories emerged from the data: The search for the maintenance of life, The technicalbureaucratic activities, The recognition of the patient s individuality, and the expression of the nurse s feelings.The analysis allowed us to describe the lived experience of the nurse s care the ICU and to comprehend the structural elements of this experience. The results showed that the nurse s experience presents itself as a process of the several actions and feelings that occur while the social relations between the patient and the nurse develop. Finally, we understand that although the study shows an experience based on a biological model of health, these nurses possess an initial idea on how to reach humanized care in its essence, needing, however, of an institutional policy that favors this practice, an educational formation that prepares her to recognize her field of work as a place of continuous learning and an understanding of the health model as an ally in the search of humanized care

Avaliação do desempenho diagnóstico e do valor de corte para o índice de respiração rápida e superficial na predição do insucesso da extubação

OBJETIVO: Avaliar o desempenho diagnóstico do índice de respiração rápida e superficial (IRRS) na predição do insucesso da extubação de pacientes adultos em terapia intensiva e verificar a adequação do valor de corte clássico para esse índice. MÉTODOS: Estudo prospectivo realizado na unidade de terapia intensiva de adultos do Hospital das Clínicas da Faculdade de Medicina de Botucatu, através da avaliação do IRRS em 73 pacientes consecutivos considerados clinicamente prontos para extubação. RESULTADOS: O IRRS com valor de corte clássico (105 ciclos/min/L) apresentou sensibilidade de 20% e especificidade de 95% (soma = 115%). A análise da curva receiver operator characteristic (ROC) demonstrou melhor valor de corte (76,5 ciclos/min/L), o qual forneceu sensibilidade de 66% e especificidade de 74% (soma = 140%), e a área sob a curva ROC para o IRRS foi de 0,78. CONCLUSÕES: O valor de corte clássico do IRRS se mostrou inadequado nesta casuística, prevendo apenas 20% dos pacientes com falha na extubação. A obtenção do novo valor de corte permitiu um acréscimo substancial de sensibilidade, com aceitável redução da especificidade. O valor da área sob a curva ROC indicou satisfatório poder discriminativo do índice, justificando a validação de sua aplicação.

Characterization of the intrahospital transport of critically ill patients

Objective: Characterizing the transport of critically ill patients in an adult intensive care unit.Methods: Cross-sectional study in which 459 intra -hospital transports of critically ill patients were included. Data were collected from clinical records of patients and from a form with the description of the materials and equipment necessary for the procedure, description of adverse events and of the transport team.Results: A total of 459 transports of 262 critically ill patients were carried out, with an average of 51 transports per month. Patients were on ventilatory support (41.3 %) and 34.5 % in use of vasoactive drugs. Adverse events occurred in 9.4% of transports and 77.3 % of the teams were composed of physicians, nurses and nurse technicians.Conclusion: The transport of critically ill patients occurred in the morning period for performing computerized tomographies (CT scans) with patients dependent on mechanical ventilation and vasoactive drugs. During the transports the equipment was functioning, and the adverse events were attributed to clinical changes of patients.

Replacement of fentanyl infusion by enteral methadone decreases the weaning time from mechanical ventilation: a randomized controlled trial

Introduction: Patients undergoing mechanical ventilation (MV) are frequently administered prolonged and/or high doses of opioids which when removed can cause a withdrawal syndrome and difficulty in weaning from MV. We tested the hypothesis that the introduction of enteral methadone during weaning from sedation and analgesia in critically ill adult patients on MV would decrease the weaning time from MV. Methods: A double-blind randomized controlled trial was conducted in the adult intensive care units (ICUs) of four general hospitals in Brazil. The 75 patients, who met the criteria for weaning from MV and had been using fentanyl for more than five consecutive days, were randomized to the methadone (MG) or control group (CG). Within the first 24 hours after study enrollment, both groups received 80% of the original dose of fentanyl, the MG received enteral methadone and the CG received an enteral placebo. After the first 24 hours, the MG received an intravenous (IV) saline solution (placebo), while the CG received IV fentanyl. For both groups, the IV solution was reduced by 20% every 24 hours. The groups were compared by evaluating the MV weaning time and the duration of MV, as well as the ICU stay and the hospital stay. Results: Of the 75 patients randomized, seven were excluded and 68 were analyzed: 37 from the MG and 31 from the CG. There was a higher probability of early extubation in the MG, but the difference was not significant (hazard ratio: 1.52 (95% confidence interval (CI) 0.87 to 2.64; P = 0.11). The probability of successful weaning by the fifth day was significantly higher in the MG (hazard ratio: 2.64 (95% CI: 1.22 to 5.69; P < 0.02). Among the 54 patients who were successfully weaned (29 from the MG and 25 from the CG), the MV weaning time was significantly lower in the MG (hazard ratio: 2.06; 95% CI 1.17 to 3.63; P < 0.004). Conclusions: The introduction of enteral methadone during weaning from sedation and analgesia in mechanically ventilated patients resulted in a decrease in the weaning time from MV.

Causes of death and determinants of outcome in critically ill patients

INTRODUCTION: Whereas most studies focus on laboratory and clinical research, little is known about the causes of death and risk factors for death in critically ill patients. METHODS: Three thousand seven hundred patients admitted to an adult intensive care unit (ICU) were prospectively evaluated. Study endpoints were to evaluate causes of death and risk factors for death in the ICU, in the hospital after discharge from ICU, and within one year after ICU admission. Causes of death in the ICU were defined according to standard ICU practice, whereas deaths in the hospital and at one year were defined and grouped according to the ICD-10 (International Statistical Classification of Diseases and Related Health Problems) score. Stepwise logistic regression analyses were separately calculated to identify independent risk factors for death during the given time periods. RESULTS: Acute, refractory multiple organ dysfunction syndrome was the most frequent cause of death in the ICU (47%), and central nervous system failure (relative risk [RR] 16.07, 95% confidence interval [CI] 8.3 to 31.4, p < 0.001) and cardiovascular failure (RR 11.83, 95% CI 5.2 to 27.1, p < 0.001) were the two most important risk factors for death in the ICU. Malignant tumour disease and exacerbation of chronic cardiovascular disease were the most frequent causes of death in the hospital (31.3% and 19.4%, respectively) and at one year (33.2% and 16.1%, respectively). CONCLUSION: In this primarily surgical critically ill patient population, acute or chronic multiple organ dysfunction syndrome prevailed over single-organ failure or unexpected cardiac arrest as a cause of death in the ICU. Malignant tumour disease and chronic cardiovascular disease were the most important causes of death after ICU discharge.
