Valeur diagnostique des micro-éveils autonomiques comme substitut aux éveils cérébraux dans l'apnée du sommeil

Les troubles respiratoires du sommeil ont une prévalence élevée dans la population générale, l’apnée obstructive du sommeil étant le plus important de ces troubles. Malgré tout, une grande proportion des patients avec apnée ne sont pas diagnostiqués. La méthode la plus complète pour diagnostiquer l’apnée est l’enregistrement d’une nuit de sommeil par polysomnographie, aussi appelée enregistrement de type 1, qui est un processus long et coûteux. Pour surmonter ces difficultés, des appareils d’enregistrements portables (ou de type 3) ont été développés. Toutefois, ces enregistrements de type 3 ne capturent pas l’activité cérébrale, mesurée avec l’électroencéphalographie (EEG). Le présent mémoire décrit une étude comparative entre les enregistrements de type 1 et de type 3. Tous les événements respiratoires d’apnée, d’hypopnée et d’éveils liés à un effort respiratoire (RERA, en anglais) seront analysés ainsi que les éveils cérébraux (ou éveils EEG) et les éveils autonomiques. Ces éveils autonomiques se définissent par une hausse de la fréquence cardiaque suite à un événement respiratoire. Pour enrichir les analyses, les variables respiratoires suivantes ont été étudiées : une chute de la saturation en oxygène de 4 % (ODI), l’index d’apnée-hypopnée (IAH), l’indice de perturbations respiratoires avec apnées + hypopnées + RERAs et les éveils EEG (RDIe, en anglais) et le RDI incluant les éveils autonomiques définis par une augmentation de la fréquence cardiaque de 5 bpm (RDIa5). L’objectif de la présente étude est d’évaluer la proportion d’événements respiratoires avec éveils autonomiques ainsi que leur impact sur le RDI des enregistrements de type 1 et 3. L’hypothèse suggère que les événements avec éveils autonomiques auraient un plus grand impact sur le RDI des enregistrements de type 3 contrairement au type 1. Cette étude inclut 72 sujets ayant suivi un enregistrement de polysomnographie complète de type 1 ainsi que 79 sujets différents ayant suivi un enregistrement ambulatoire de type 3. Les analyses suivantes ont été effectuées : 1) les pourcentages d’événements associés avec seulement des éveils autonomiques dans les enregistrements de type 1 et de type 3 ; 2) les fréquences de migration entre les catégories basses et élevées de sévérité de l’AHI en prenant en compte les événements associés avec seulement des éveils autonomiques ; 3) les Bland-Altman (B-A) pour mesurer l’accord entre l’AHI, le RDIe et le RDIa5 (type 1), et entre l’AHI et le RDIa5 (type 3) et ; 4) les corrélations de Pearson et les coefficients de corrélation intraclasse (ICC) pour mesurer l’accord entre l’AHI, le RDIe et le RDIa5 (type 1), et entre l’AHI et le RDIa5 (type 3). L’utilisation du critère de RDIa5 permet d’ajouter 49 % d’événements comptés avec l’AHI pour les enregistrements de type 1, et 51 % d’événements pour ceux de type 3. La présente étude montre que les éveils autonomiques ont un impact similaire autant pour le RDI des enregistrements de type 3 que de type 1. En conclusion, on peut affirmer que le RDIa5 est acceptable et fiable pour les enregistrements de type 3.

Child Health Care in Ireland

The Irish health care system is based on a complex and costly mix of private, statutory, and voluntary provisions. The majority of health care expenditure comes from the state, with a significant proportion of acute hospital care funded from private insurance, but there are relatively high out-of-pocket costs for most service users. There is free access to acute hospital care, but not for primary care, for all children. About 40% of the population have free access to primary care. Universal preventive public health services, including vaccination and immunization, newborn blood spot screening, and universal neonatal hearing screening are free. Major health challenges include poverty, obesity, drug and alcohol use, and mental health. The health care system has been dominated for the last 5 years by the impact of the current recession, which has led to very sharp cuts in health care expenditure. It is unclear if the necessary substantial reform of the system will happen. Government policy calls for a move toward a patient-centered, primary care-led system, but without very substantial transfers of resources and investment in Information and Communication Technology, this is unlikely to occur.

Children with Special Health Care Needs: Comparison of the Effects of Home Care Setting, Prescribed Pediatric Extended Care Setting, and Long-Term Care Setting on Child and Family Health Outcomes and Health Care Service Use

Technological advances during the past 30 years have dramatically improved survival rates for children with life-threatening conditions (preterm births, congenital anomalies, disease, or injury) resulting in children with special health care needs (CSHCN), children who have or are at increased risk for a chronic physical, developmental, behavioral, or emotional condition and who require health and related services beyond that required by children generally. There are approximately 10.2 million of these children in the United States or one in five households with a child with special health care needs. Care for these children is limited to home care, medical day care (Prescribed Pediatric Extended Care; P-PEC) or a long term care (LTC) facility. There is very limited research examining health outcomes of CSHCN and their families. The purpose of this research was to compare the effects of home care settings, P-PEC settings, and LTC settings on child health and functioning, family health and function, and health care service use of families with CSHCN. Eighty four CSHCN ages 2 to 21 years having a medically fragile or complex medical condition that required continual monitoring were enrolled with their parents/guardians. Interviews were conducted monthly for five months using the PedsQL TM Generic Core Module for child health and functioning, PedsQL TM Family Impact Module for family health and functioning, and Access to Care from the NS-CSHCN survey for health care services. Descriptive statistics, chi square, and ANCOVA were conducted to determine differences across care settings. Children in the P-PEC settings had a highest health care quality of life (HRQL) overall including physical and psychosocial functioning. Parents/guardians with CSHCN in LTC had the highest HRQL including having time and energy for a social life and employment. Parents/guardians with CSHCN in home care settings had the poorest HRQL including physical and psychosocial functioning with cognitive difficulties, difficulties with worry, communication, and daily activities. They had the fewest hours of employment and the most hours providing direct care for their children. Overall health care service use was the same across the care settings.

Satisfaction of users of primary health care with nursing care : sample of the central region of Portugal

Introdução: A satisfação dos doentes constitui um indicador indispensável para a avaliação da qualidade dos cuidados e há evidência da sua correlação com os resultados em saúde. A satisfação com os cuidados de saúde é um conceito multidimensional que considera aspetos como acesso, organização e interação doente - profissional. Consideramos que os cuidados de enfermagem, em particular, são fundamentais no processo saúde/doença. Objetivos: Validar uma escala para avaliar a satisfação dos utentes face aos cuidados de enfermagem, adaptado do instrumento EUROPEP e avaliar a satisfação dos utentes dos cuidados de saúde primários da região centro de Portugal. Material e métodos: Estudo transversal, com uma amostra de 827 utentes adultos (maioria do sexo feminino 64,4%) com uma média de idade de 50,08±18,58 anos. Os dados foram recolhidos através de um questionário, constituído por variáveis sociodemográficas, o instrumento EUROPEP (Ferreira, 1995) para avaliar a satisfação com os cuidados de saúde primários e para avaliar a satisfação especificamente com a equipa de enfermagem elaboramos questões adaptadas do instrumento EUROPEP e agrupadas nas dimensões relação de ajuda, dimensão interpessoal e instrumental. A consistência interna, reprodutibilidade e análise de conteúdo foram avaliados com recurso ao SPSS 23.0; considerando a consistência aceitável para um de Cronbach > 0,70. O coeficiente para cada item é apresentado com um intervalo de confiança de 95%. Resultados: Em todas as dimensões do questionário EUROPEP, a maior percentagem de satisfação com os cuidados situou-se entre “boa” e “muito boa”. As dimensões criadas para avaliar especificamente os cuidados de enfermagem apresentaram um coeficiente de α de Cronbach total de 0,972. Conclusões: Estes resultados sugerem que as dimensões criadas para avaliar os cuidados de enfermagem serão úteis para a investigação na população Portuguesa. A satisfação do utente é decisiva para a qualidade e eficiência dos cuidados prestados, sendo necessário o compromisso de todos os prestadores na implementação de práticas sistemáticas de gestão que conduzam à satisfação, dando particular atenção à melhoria contínua dos processos organizacionais.

Health care-associated native valve endocarditis: importance of non-nosocomial acquisition.

BACKGROUND: The clinical profile and outcome of nosocomial and non-nosocomial health care-associated native valve endocarditis are not well defined. OBJECTIVE: To compare the characteristics and outcomes of community-associated and nosocomial and non-nosocomial health care-associated native valve endocarditis. DESIGN: Prospective cohort study. SETTING: 61 hospitals in 28 countries. PATIENTS: Patients with definite native valve endocarditis and no history of injection drug use who were enrolled in the ICE-PCS (International Collaboration on Endocarditis Prospective Cohort Study) from June 2000 to August 2005. MEASUREMENTS: Clinical and echocardiographic findings, microbiology, complications, and mortality. RESULTS: Health care-associated native valve endocarditis was present in 557 (34%) of 1622 patients (303 with nosocomial infection [54%] and 254 with non-nosocomial infection [46%]). Staphylococcus aureus was the most common cause of health care-associated infection (nosocomial, 47%; non-nosocomial, 42%; P = 0.30); a high proportion of patients had methicillin-resistant S. aureus (nosocomial, 57%; non-nosocomial, 41%; P = 0.014). Fewer patients with health care-associated native valve endocarditis had cardiac surgery (41% vs. 51% of community-associated cases; P < 0.001), but more of the former patients died (25% vs. 13%; P < 0.001). Multivariable analysis confirmed greater mortality associated with health care-associated native valve endocarditis (incidence risk ratio, 1.28 [95% CI, 1.02 to 1.59]). LIMITATIONS: Patients were treated at hospitals with cardiac surgery programs. The results may not be generalizable to patients receiving care in other types of facilities or to those with prosthetic valves or past injection drug use. CONCLUSION: More than one third of cases of native valve endocarditis in non-injection drug users involve contact with health care, and non-nosocomial infection is common, especially in the United States. Clinicians should recognize that outpatients with extensive out-of-hospital health care contacts who develop endocarditis have clinical characteristics and outcomes similar to those of patients with nosocomial infection. PRIMARY FUNDING SOURCE: None.

Do health care providers use online patient ratings to improve the quality of care?

Background: Physician-rating websites have become a popular tool to create more transparency about the quality of health care providers. So far, it remains unknown whether online-based rating websites have the potential to contribute to a better standard of care. Objective: Our goal was to examine which health care providers use online rating websites and for what purposes, and whether health care providers use online patient ratings to improve patient care. Methods: We conducted an online-based cross-sectional study by surveying 2360 physicians and other health care providers (September 2015). In addition to descriptive statistics, we performed multilevel logistic regression models to ascertain the effects of providers' demographics as well as report card-related variables on the likelihood that providers implement measures to improve patient care. Results: Overall, more than half of the responding providers surveyed (54.66%, 1290/2360) used online ratings to derive measures to improve patient care (implemented measures: mean 3.06, SD 2.29). Ophthalmologists (68%, 40/59) and gynecologists (65.4%, 123/188) were most likely to implement any measures. The most widely implemented quality measures were related to communication with patients (28.77%, 679/2360), the appointment scheduling process (23.60%, 557/2360), and office workflow (21.23%, 501/2360). Scaled-survey results had a greater impact on deriving measures than narrative comments. Multilevel logistic regression models revealed medical specialty, the frequency of report card use, and the appraisal of the trustworthiness of scaled-survey ratings to be significantly associated predictors for implementing measures to improve patient care because of online ratings. Conclusions: Our results suggest that online ratings displayed on physician-rating websites have an impact on patient care. Despite the limitations of our study and unintended consequences of physician-rating websites, they still may have the potential to improve patient care.
