; P=0.041). Conclusions-PVR after repair of tetralogy of Fallot has a low and improving mortality, with a low need for reintervention.Preoperative cardiopulmonary exercise testing predicts surgical outcome and should therefore be included in the routine assessment of these patients.

Objectives: To understand from the perspective of patients who did, and did not attend ICU recovery programs, what were the most important components of successful programs and how should they be organized. Design: International, qualitative study. Setting: Fourteen hospitals in the United States, United Kingdom, and Australia. Patients: We conducted 66 semi-structured interviews with a diverse group of patients, 52 of whom had used an ICU recovery program and 14 whom had not. Interventions: None. Measurements and Main Results: Using content analysis, prevalent themes were documented to understand what improved their outcomes. Contrasting quotes from patients who had not received certain aspects of care were used to identify perceived differential effectiveness. Successful ICU recovery programs had five key components: 1) Continuity of care; 2) Improving symptom status; 3) Normalization and expectation management; 4) Internal and external validation of progress; and 5) Reducing feelings of guilt and helplessness. The delivery of care which achieved these goals was facilitated by early involvement (even before hospital discharge), direct involvement of ICU staff, and a focus on integration across traditional disease, symptom, and social welfare needs. Conclusions: In this multicenter study, conducted across three continents, patients identified specific and reproducible modes of benefit derived from ICU recovery programs, which could be the target of future intervention refinement.

Objective To identify the key mechanisms that clinicians perceive improve care in the intensive care unit (ICU), as a result of their involvement in post-ICU programs. Methods Qualitative inquiry via focus groups and interviews with members of the Society of Critical Care Medicine’s THRIVE collaborative sites (follow-up clinics and peer support). Framework analysis was used to synthesize and interpret the data. Results Five key mechanisms were identified as drivers of improvement back into the ICU: (1) identifying otherwise unseen targets for ICU quality improvement or education programs—new ideas for quality improvement were generated and greater attention paid to detail in clinical care. (2) Creating a new role for survivors in the ICU—former patients and family members adopted an advocacy or peer volunteer role. (3) Inviting critical care providers to the post-ICU program to educate, sensitize, and motivate them—clinician peers and trainees were invited to attend as a helpful learning strategy to gain insights into post-ICU care requirements. (4) Changing clinician’s own understanding of patient experience—there appeared to be a direct individual benefit from working in post-ICU programs. (5) Improving morale and meaningfulness of ICU work—this was achieved by closing the feedback loop to ICU clinicians regarding patient and family outcomes. Conclusions The follow-up of patients and families in post-ICU care settings is perceived to improve care within the ICU via five key mechanisms. Further research is required in this novel area.

Brucellergene OCB (Rhône-Mérieux) was used as an allergen to define the intrinsic parameters of a skin test and to compare its properties with serology for the diagnosis of bovine brucellosis. The skin test was also evaluated for its capacity to solve problems associated with false positive reactions in serological tests. The optimal reading delay for the skin test was 72 hours. The brucellosis allergic reaction was two to three times less intense than the tuberculosis allergic reaction. An increase of 1.1 mm or more in the skin thickness was therefore considered to be an adequate cut-off. The specificity calculated for 1192 brucellosis-free animals (including animals from brucellosis-free herds in which false positive serological reactions had been reported) was 99-83 per cent (95 per cent confidence interval [CI] 99-40 to 99-98 per cent). The sensitivity determined from 27 experimentally infected heifers ranged from 93 per cent (95 per cent CI 76 to 100 per cent) to 78 per cent (95 per cent CI 58 to 91 per cent) when measured respectively one and six months after the infection. Allergic reactions could be detected in vaccinated animals up to four-and-a-half years after the vaccination. On the other hand, no sensitisation was recorded in naïve animals after up to eight monthly injections of the allergen. The skin test gave valuable information, in combination with the serological tests, in both acute and chronic brucellosis. The skin test discriminated brucellosis clearly from false positive serological reactions due to infections with Yersinia enterocolitica O9.

Objective-Investigate the challenges experienced by survivors of critical illness and their caregivers across the transitions of care from intensive care to community, and the potential problem-solving strategies used to navigate these challenges.Design-Qualitative design -data generation via interviews and data analysis via the Framework Analysis method.Setting-Patients and caregivers from three continents, identified through the Society of Critical Care Medicine's THRIVE international collaborative sites (follow-up clinics and peer support groups). Subjects-Patients and caregivers following critical illness. Interventions-NilMeasurements and Main Results-From 86 interviews (66 patients, 20 caregivers), we identified the following major themes: 1. Challenges for patients -Interacting with the health system and gaps in care; Managing others' expectations of illness and recovery; 2. Challenges for caregivers -Health system shortfalls and inadequate communication; and Lack of support for caregivers. 3. Patient and caregiver-driven problem solving across the transitions of care -Personal attributes, resources, and initiative; Receiving support and helping others; and Acceptance.Conclusions-Survivors and caregivers experienced a range of challenges across the transitions of care. There were distinct and contrasting themes related to the caregiver experience. Survivors and caregivers used comparable problem-solving strategies to navigate the challenges encountered across the transitions of care.Haines et al.

SummaryThe use of selective decontamination of the digestive tract (SDD) remains controversial despite several large randomised-controlled trials and meta-analyses. A postal survey of intensive care units in the United Kingdom was conducted to document current use of SDD, and to identify factors influencing this practice. The response rate was 71%. The vast majority (182 units, 95%) do not use SDD mainly because practising clinicians do not believe it works or that there is not enough evidence (51%), and because of concerns about antibiotic resistance (47%). Of the 10 units using SDD, three apply it to all intubated patients and five do not use intravenous antibiotics in their protocol.
