RESUMO

BACKGROUND: Prolonging life in the ICU increasingly is possible, so decisions to limit life-sustaining therapies frequently are made and communicated to patients and families or surrogates. Little is known about worldwide communication practices and influencing factors. RESEARCH QUESTION: Are there regional differences in end-of-life communication practices in ICUs worldwide? STUDY DESIGN AND METHODS: This analysis of data from a prospective, international study specifically addressed end-of-life communications in consecutive patients who died or had limitation of life-sustaining therapy over 6 months in 199 ICUs in 36 countries, grouped regionally. End-of-life decisions were recorded for each patient and ethical practice was assessed retrospectively for each ICU using a 12-point questionnaire developed previously. RESULTS: Of 87,951 patients admitted, 12,850 died or experienced a limitation of therapy (14.6%). Of these, 1,199 patients (9.3%) were known to have an advance directive, and wishes were elicited from 6,456 patients (50.2%). Limitations of life-sustaining therapy were implemented for 10,401 patients (80.9%), 1,970 (19.1%) of whom had mental capacity at the time, and were discussed with 1,507 patients (14.5%) and 8,461 families (81.3%). Where no discussions with patients occurred (n = 8,710), this primarily was because of a lack of mental capacity in 8,114 patients (93.2%), and where none occurred with families (n = 1,622), this primarily was because of unavailability (n = 720 [44.4%]). Regional variation was noted for all end points. In generalized estimating equation (GEE) analyses, the odds for discussions with the patient or family increased by 30% (OR, 1.30; 95% CI, 1.18-1.44; P < .001) for every one-point increase in the Ethical Practice Score and by 92% (OR, 1.92; 95% CI, 1.28-2.89; P = .002) in the presence of an advance directive. INTERPRETATION: End-of-life communication with patients and families or surrogates varies markedly in different global regions. GEE analysis supports the hypothesis that communication may increase with ethical practice and an advance directive. Greater effort is needed to align treatment with patients' wishes.

RESUMO

BACKGROUND AND OBJECTIVE: An influenza pandemic has the potential to overwhelm intensive care resources, but the views of the general public on how resources should be allocated in such a scenario were unknown. We aimed to determine Australian and New Zealand public opinion on how intensive care unit beds should be allocated during an influenza pandemic. DESIGN, SETTING, AND PARTICIPANTS: A postal questionnaire was sent to 4000 randomly selected registered voters; 2000 people each from the Australian Electoral Commission and New Zealand Electoral Commission rolls. MAIN OUTCOME MEASURE: The respondents' preferred method to triage ICU patients in an influenza pandemic. Respondents chose from six methods: use a "first in, first served" approach; allow a senior doctor to decide; use pre-determined health department criteria; use random selection; use the patient's ability to pay; use the importance of the patient to decide. Respondents also rated each of the triage methods for fairness. RESULTS: Australian respondents preferred that patients be triaged to the ICU either by a senior doctor (43.2%) or by pre-determined health department criteria (38.7%). New Zealand respondents preferred that triage be performed by a senior doctor (45.9%). Respondents from both countries perceived triage by a senior doctor and by pre-determined health department criteria to be fair, and the other four methods of triage to be unfair. CONCLUSION: In an influenza pandemic, when ICU resources would be overwhelmed, survey respondents preferred that ICU triage be performed by a senior doctor, but also perceived the use of pre-determined triage criteria to be fair.

RESUMO

We report 4 cases of Health Workers (HW) suspected of having contracted Ebola Virus Disease (EVD), transported from the Alliance for International Medical Action (ALIMA) Ebola Treatment Centre (ETC) in N'Zerekore, Guinea to the Treatment Centre for Carers run by the medical corps of the French army in Conakry, the capital of Guinea, which was established on 17 January 2015 and closed on 7 July 2015. In total more than 500 HWs have died from EVD since the epidemic began. This mortality has had significant effects on the ability of local services to respond appropriately to the disaster. The HWs were transported by air in the "Human Stretcher Transit Isolator-Total Containment (Oxford) Limited" (HSTI-TCOL) negative pressure isolation pod. Medical evacuation of patients with suspected, potentially fatal, infectious diseases is feasible with the use of a light isolator for patients without critical dysfunctions.

RESUMO

BACKGROUND: Community health workers (CHWs) are recommended to screen for acute malnutrition in the community by assessing mid-upper arm circumference (MUAC) on children between 6 and 59 months of age. MUAC is a simple screening tool that has been shown to be a better predictor of mortality in acutely malnourished children than other practicable anthropometric indicators. This study compared, under program conditions, mothers and CHWs in screening for severe acute malnutrition (SAM) by color-banded MUAC tapes. METHODS: This pragmatic interventional, non-randomized efficacy study took place in two health zones of Niger's Mirriah District from May 2013 to April 2014. Mothers in Dogo (Mothers Zone) and CHWs in Takieta (CHWs Zone) were trained to screen for malnutrition by MUAC color-coded class and check for edema. Exhaustive coverage surveys were conducted quarterly, and relevant data collected routinely in the health and nutrition program. An efficacy and cost analysis of each screening strategy was performed. RESULTS: A total of 12,893 mothers and caretakers were trained in the Mothers Zone and 36 CHWs in the CHWs Zone, and point coverage was similar in both zones at the end of the study (35.14 % Mothers Zone vs 32.35 % CHWs Zone, p = 0.9484). In the Mothers Zone, there was a higher rate of MUAC agreement (75.4 % vs 40.1 %, p <0.0001) and earlier detection of cases, with median MUAC at admission for those enrolled by MUAC <115 mm estimated to be 1.6 mm higher using a smoothed bootstrap procedure. Children in the Mothers Zone were much less likely to require inpatient care, both at admission and during treatment, with the most pronounced difference at admission for those enrolled by MUAC < 115 mm (risk ratio = 0.09 [95 % CI 0.03; 0.25], p < 0.0001). Training mothers required higher up-front costs, but overall costs for the year were much lower ($8,600 USD vs $21,980 USD.). CONCLUSIONS: Mothers were not inferior to CHWs in screening for malnutrition at a substantially lower cost. Children in the Mothers Zone were admitted at an earlier stage of SAM and required fewer hospitalizations. Making mothers the focal point of screening strategies should be included in malnutrition treatment programs. TRIAL REGISTRATION: The trial is registered with clinicaltrials.gov (Trial number NCT01863394).

RESUMO

BACKGROUND: Mid-upper arm circumference (MUAC) was recently endorsed and recommended for screening for acute malnutrition in the community. The objective of this study was to determine whether a colour-banded MUAC strap would allow minimally trained mothers to screen their own children for malnutrition, without locating the mid-point of the left upper arm by measurement, as currently recommended. METHODS: A non-randomised non-blinded evaluation of mothers' performance when measuring MUAC after minimal training, compared with trained Community Health Workers (CHW) following current MUAC protocols. The study was conducted in 2 villages in Mirriah, Zinder region, Niger where mothers classified one of their children (n = 103) aged 6-59 months (the current age range for admission into community malnutrition programs) using the MUAC tape. RESULTS: Mothers' had a sensitivity and specificity for classification of their child's nutritional status of > 90% and > 80% respectively for global acute malnutrition (GAM, defined by a MUAC < 125 mm) and > 73% and > 98% for severe acute malnutrition (SAM, defined by a MUAC < 115 mm). The few children misclassified as not having SAM, were classified as having moderate acute malnutrition (MAM). The choice of arm did not influence the classification results; weighted Kappa of 0.88 for mothers and 0.91 for CHW represent almost perfect agreement. Errors occurred at the class boundaries and no gross errors were made. CONCLUSIONS: Advanced SAM is associated with severe complications, which often require hospital admission or cause death. Mothers (with MUAC tapes costing $0.06) can screen their children frequently allowing early diagnosis and treatment thereby becoming the focal point in scaling-up community management of acute malnutrition. TRIAL REGISTRATION: The trial is registered with clinicaltrials.gov (Trial number NCT01790815).

RESUMO

Background Severe limb trauma is common in earthquake survivors. Overall medium term outcomes and patient-perceived outcomes are poorly documented. Methods and Findings The prospective study SuTra2 assessed the functional and socio-economic status of a cohort of patients undergoing surgery for limb injury resulting in amputation (A) or limb preservation (LP) one year and two years after the 2010 Haiti earthquake. 305 patients [A: n=199 (65%), LP: n=106 (35%)] were evaluated. Their characteristics were: 57% female; mean age 31 years; 74% of principal injuries involved the lower limb; 46% of patients had an additional severe injury; 60% had fractures, of which two-thirds were compound or associated with severe soft tissue damage; 15% of amputations were traumatic. At 2 years, 51% of patients were satisfied with the functional outcome (A: 52%, LP: 49%, ns). Comparison with the 1-year status indicates a worsening of the perceived functional status, significantly more pronounced in amputees, and an increase in pain complaints, mainly in amputees (62% and 80% of pain in overall population at 1- and 2-year respectively). Twenty eight percent (28%) of LP and 66% of A considered themselves as "cured". 100% of LP and 79% of A would have chosen a conservative approach if an amputation was medically avoidable. Two years after the earthquake, 23·5 % of patients were still living in a tent, 30% were working, and 25·5% needed ongoing surgical management. Conclusions Only half the patients with severe limb injuries, whether managed with amputation or limb preservation, deemed their functional status satisfactory at 2 years. The patients' perspective, clearly favors limb conservative management whenever possible. Prolonged care and rehabilitation are needed to optimize the outcome for earthquake survivors with limb injuries. Humanitarian respondents to catastrophes have professional and ethical obligations to provide optimal immediate care and ensure scrupulous attention to long-term management. Keywords Haiti earthquake, limb injury, two-year outcome, patients' perspective, amputation, limb salvage.

RESUMO

OBJECTIVES: To develop an influenza pandemic ICU triage (iPIT) protocol that excludes patients with the highest and lowest predicted mortality rates, and to determine the increase in ICU bed availability that would result. DESIGN AND SETTING: Post-hoc analysis of a study evaluating two triage protocols, designed to determine which patients should be excluded from access to ICU resources during an influenza pandemic. ICU mortality rates were determined for the individual triage criteria in the protocols and included criteria based on the Sequential Organ Failure Assessment (SOFA) score. Criteria resulting in mortality rates outside the 25th and 75th percentiles were used as exclusion criteria in a new iPIT-1 protocol. The SOFA threshold component was modified further and reported as iPIT-2 and iPIT-3. MAIN OUTCOME MEASURE: Increase in ICU bed availability. RESULTS: The 25th and 75th percentiles for ICU mortality were 8.3% and 35.2%, respectively. Applying the iPIT-1 protocol resulted in an increase in ICU bed availability at admission of 71.7% ± 0.6%. Decreasing the lower SOFA score exclusion criteria to ≤6 (iPIT-2) and ≤4 (iPIT-3) resulted in an increase in ICU bed availability at admission of 66.9% ± 0.6% and 59.4 ± 0.7%, respectively (P < 0.001). CONCLUSION: The iPIT protocol excludes patients with the lowest and highest ICU mortality, and provides increases in ICU bed availability. Adjusting the lower SOFA score exclusion limit provides a method of escalation or de- escalation to cope with demand.

RESUMO

OBJECTIVE: To determine the increase in intensive care unit (ICU) bed availability that would result from the use of the New South Wales and Ontario Health Plan for an Influenza Pandemic (OHPIP) triage protocols. DESIGN, SETTING AND PATIENTS: Prospective evaluation study conducted in eight Australian, adult, general ICUs, between September 2009 and May 2010. All patients who were admitted to the ICU, excluding those who had elective surgery, were prospectively evaluated using the two triage protocols, simulating a pandemic situation. Both protocols were originally developed to determine which patients should be excluded from accessing ICU resources during an influenza pandemic. MAIN OUTCOME MEASURE: Increase in ICU bed availability. RESULTS: At admission, the increases in ICU bed availability using Tiers 1, 2 and 3 of the NSW triage protocol were 3.5%, 14.7% and 22.7%, respectively, and 52.8% using the OHPIP triage protocol (P < 0.001). Re-evaluation of patients at 12 hours after admission using Tiers 1, 2 and 3 of the NSW triage protocol incrementally increased ICU bed availability by 19.2%, 16.1% and 14.1%, respectively (P < 0.001). The maximal cumulative increases in ICU bed availability using Tiers 1, 2 and 3 of the NSW triage protocol were 23.7%, 31.6% and 37.5%, respectively, at 72 hours (P < 0.001), and 65.0% using the OHPIP triage protocol, at 120 hours (P < 0.001). CONCLUSION: Both triage protocols resulted in increases in ICU bed availability, but the OHPIP protocol provided the greatest increase overall. With the NSW triage protocol, ICU bed availability increased as the protocol was escalated.

RESUMO

BACKGROUND: War-related orthopedic injury is frequently complicated by environmental contamination and delays in management, placing victims at increased risk for long-term infectious complications. We describe, among Iraqi civilians with war-related chronic osteomyelitis, the bacteriology of infection at the time of admission. METHODS: In the Médecins Sans Frontières Reconstructive Surgery Project in Amman, Jordan, we retrospectively reviewed baseline demographics and results of initial intraoperative surgical cultures among Iraqi civilians with suspected osteomyelitis. RESULTS: One hundred thirty-seven patients (90% male; median age, 35 years [interquartile range {IQR}, 28-46]; median time since initial injury, 19 months [IQR, 10-35]) were admitted with suspected chronic osteomyelitis after war-related injury. One hundred seven patients had a positive intraoperative culture. Before arrival, patients had undergone a median of 4 (IQR, 2-6) surgical procedures in Iraq. Fifty-nine (55%) of 107 patients with confirmed osteomyelitis had a multidrug-resistant (MDR) organism isolated at admission: cefepime-resistant Enterobacteriaceae (n = 40), methicillin-resistant Staphylococcus aureus (n = 16), and MDR Acinetobacter baumannii (n = 3). An association of borderline significance existed between a history of more than two prior surgical procedures in Iraq and an MDR isolate at program entry (multivariate: odds ratio, 5.3; 95% confidence interval, 0.9-30.6; p = 0.064). CONCLUSION: Health care actors, including Iraqi health facilities and humanitarian medical organizations, must be aware of the link between chronic war injury and antimicrobial drug resistance in this region and should be prepared for the management challenges involved with the treatment of chronic drug-resistant osteomyelitis.

RESUMO

Involvement of the pericardium and pericardial effusion at postmortem is common in advanced malignant disease. However, cardiac tamponade presenting as the first manifestation of malignancy is uncommon. We present the case of a patient who presented with malignant pericardial effusion who had advanced lung cancer with metastasis and paraneoplastic features.

RESUMO

CONTEXT: The novel influenza A(H1N1) pandemic affected Australia and New Zealand during the 2009 southern hemisphere winter. It caused an epidemic of critical illness and some patients developed severe acute respiratory distress syndrome (ARDS) and were treated with extracorporeal membrane oxygenation (ECMO). OBJECTIVES: To describe the characteristics of all patients with 2009 influenza A(H1N1)-associated ARDS treated with ECMO and to report incidence, resource utilization, and patient outcomes. DESIGN, SETTING, AND PATIENTS: An observational study of all patients (n = 68) with 2009 influenza A(H1N1)-associated ARDS treated with ECMO in 15 intensive care units (ICUs) in Australia and New Zealand between June 1 and August 31, 2009. MAIN OUTCOME MEASURES: Incidence, clinical features, degree of pulmonary dysfunction, technical characteristics, duration of ECMO, complications, and survival. RESULTS: Sixty-eight patients with severe influenza-associated ARDS were treated with ECMO, of whom 61 had either confirmed 2009 influenza A(H1N1) (n = 53) or influenza A not subtyped (n = 8), representing an incidence rate of 2.6 ECMO cases per million population. An additional 133 patients with influenza A received mechanical ventilation but no ECMO in the same ICUs. The 68 patients who received ECMO had a median (interquartile range [IQR]) age of 34.4 (26.6-43.1) years and 34 patients (50%) were men. Before ECMO, patients had severe respiratory failure despite advanced mechanical ventilatory support with a median (IQR) Pao(2)/fraction of inspired oxygen (Fio(2)) ratio of 56 (48-63), positive end-expiratory pressure of 18 (15-20) cm H(2)O, and an acute lung injury score of 3.8 (3.5-4.0). The median (IQR) duration of ECMO support was 10 (7-15) days. At the time of reporting, 48 of the 68 patients (71%; 95% confidence interval [CI], 60%-82%) had survived to ICU discharge, of whom 32 had survived to hospital discharge and 16 remained as hospital inpatients. Fourteen patients (21%; 95% CI, 11%-30%) had died and 6 remained in the ICU, 2 of whom were still receiving ECMO. CONCLUSIONS: During June to August 2009 in Australia and New Zealand, the ICUs at regional referral centers provided mechanical ventilation for many patients with 2009 influenza A(H1N1)-associated respiratory failure, one-third of whom received ECMO. These ECMO-treated patients were often young adults with severe hypoxemia and had a 21% mortality rate at the end of the study period.
