ABSTRACT:

Objectives

To clarify the procedures related to mechanical ventilation in the intensive care unit setting: allocation of ventilators, team education, maintenance and reference documents.

Study design

Declarative survey.

Methods

Between September and December 2010, we assessed the assignment and types of ventilators (ICU ventilators, temporary repair ventilators, non-invasive ventilators [NIV], and transportation ventilators), medical and nurse education, maintenance of the ventilators, presence of reference documents. Results are expressed in median/range and proportions.

Results

Among the 62 participating ICUs, a median of 15 ventilators/ICU (range 1-50) was reported with more than one trademark in 47 (76%) units. Specific ventilators were used for NIV in 22 (35%) units, temporary repair in 49 (79%) and transportation in all the units. Nurse education courses were given by ICU physicians in 54 (87%) units or by a company in 29 (47%) units. Medical education courses were made by ICU senior physicians in 55 (89%) units or by a company in 21 (34%) units. These courses were organized occasionally in 24 (39%) ICU and bi-annually in 16 (26%) units. Maintenance procedures were made by the ICU staff in 39 (63%) units, dedicated staff (17 [27%]) or bioengineering technicians (14 [23%] ICU). Reference documents were written for maintenance procedures in 48 (77%) units, ventilator setup in 22 (35%) units and ventilator dysfunction in 20 (32%) ICU.

Conclusions

This first survey shows disparate distribution of ventilators and practices among French ICU. Education and understanding of the proper use of ventilators are key issues for security improvement.

Project description:BackgroundIn the intensive care unit (ICU), critical illness delirium occurs in the context of multiple comorbidities, multi-organ failure, and invasive management techniques, such as mechanical ventilation, sedation, and lack of sleep. Delirium is characterized by an acute confusional state defined by fluctuating mental status, inattention, and either disorganized thinking or an altered level of consciousness. The long-term cognitive and psychosocial function of patients that experience delirium in the ICU is of crucial interest because preliminary data suggest a strong association between ICU-related delirium and long-term cognitive impairment.ObjectiveThe aim of this study is to explore the relationship between delirium in the ICU and adverse outcomes by following mechanically ventilated patients for one year following their discharge from the ICU and collecting data on their long-term cognition and psychosocial function.MethodsThis study will be conducted by enrolling patients in two tertiary ICUs in Australia. We aim to recruit 200 patients who have been mechanically ventilated for more than 24 hours. Data will be collected at the following three time points: (1) at discharge where they will be administered the Mini-Mental State Examination (MMSE); (2) at 6 months after discharge from the ICU discharge where the Impact of Events Scale Revised (IES-R) and the Telephone Inventory for Cognitive Status (TICS) tests will be administered; and (3) at 12 months after discharge from the ICU where the patients will be administered the TICS and IES-R tests, as well as the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE). The IQCODE will be administered to their "person responsible" or the significant other of the patient.ResultsLong-term cognition and psychosocial function will be the primary outcome of this study. Mortality will also be investigated as a secondary outcome. Active enrollment will take place until the end of September 2016 and data collection will conclude at the end of September 2017. The analysis and results are expected to be available by March 2018.ConclusionDelirium during mechanical ventilation has been linked to longer ICU and hospital stays, higher financial burdens, increased risks of long-term cognitive impairment (ie, dementia), poor functional outcomes and quality of life, and decreased survival. However, delirium during mechanical ventilation in the ICU is not well understood. This study will advance our knowledge of the comprehensive, long-term effects of delirium on cognitive and psychosocial function.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12616001116415; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=371216 (Archived by WebCite at http://www.webcitation.org/ 6nfDkGTcW).

Project description:BackgroundSedation is used frequently for patients in intensive care units who require mechanical ventilation, but oversedation is one of the main side effects. Different strategies have been proposed to prevent oversedation. The extent to which these strategies have been adopted by intensivists is unknown.MethodsWe developed a six-section questionnaire that covered the drugs used, modalities of drug administration, use of sedation scales and procedural pain scales, use of written local procedures, and targeted objectives of consciousness. In November 2011, the questionnaire was sent to 1,078 intensivists identified from the French ICU Society (SRLF) database.ResultsThe questionnaire was returned by 195 intensivists (response rate 18.1%), representing 135 of the 282 ICUs (47.8%) listed in the French ICU society (SRLF) database. The analysis showed that midazolam and sufentanil are the most frequently used hypnotics and opioids, respectively, administered in continuous intravenous (IV) infusions. IV boluses of hypnotics without subsequent continuous IV infusion are used occasionally (in <25% of patients) by 65% of intensivists. Anxiolytic benzodiazepines (e.g., clorazepam, alprazolam), hydroxyzine, and typical neuroleptics, via either an enteral or IV route, are used occasionally by two thirds of respondents. The existence of a written, local sedation management procedure in the ICU is reported by 55% of respondents, 54% of whom declare that they use it routinely. Written local sedation procedures mainly rely on titration of continuous IV hypnotics (90% of the sedation procedures); less frequently, sedation procedures describe alternative approaches to prevent oversedation, including daily interruption of continuous IV hypnotic infusion, hypnotic boluses with no subsequent continuous IV infusion, or the use of nonhypnotic drugs. Among the responding intensivists, 98% consider eye opening, either spontaneously or after light physical stimulation, a reasonable target consciousness level in patients with no severe respiratory failure or intracranial hypertension.ConclusionsDespite a low individual response rate, the respondents to our survey represent almost half of the ICUs in the French SRLF database. The presence of a written local sedation procedure, a cornerstone of preventing oversedation, is reported by only half of respondents; when present, it is used in for a limited number of patients. Sedation procedures mainly rely on titration of continuous IV hypnotics, but other strategies to limit oversedation also are included in sedation procedures. French intensivists no longer consider severely altered consciousness a sedation objective for most patients.

Project description:Background:The aging of the US population has been associated with an increase in intensive care unit (ICU) utilization and correspondingly, invasive mechanical ventilation (IMV) among the oldest-old (age ?80 years). While previous studies have examined ICU and IMV outcomes in the elderly, very few have focused on patient-centered outcomes, specifically home return, in the oldest-old. We investigated the rate of immediate home return following IMV in the medical ICU in previously home-dwelling oldest-old patients relative to that of a comparison group of 50-70-year olds. Methods:Data were extracted retrospectively from patient records at Elmhurst Hospital Center in Elmhurst, NY, USA, encompassing the period from January 2009 to May 2014 and Jacobi Medical Center in the Bronx, NY, USA, from January 2010 to March 2014. Medical ICU admissions within those date ranges were screened for possible inclusion into one of two study groups based on age: ?80 years old and 50-70 years old. The primary end point was hospital discharge: home return versus no home return (death or nonhome discharge). Cox proportional hazards' regression models were used to estimate crude and multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for failure to return home. Results:A total of 375 patients were included in the analysis: 279 (74%) patients aged 50-70 years and 96 (26%) patients aged ?80 years. Compared to 50-70-year olds, being ?80 years old was associated with a nearly two-fold greater risk of no home return: adjusted HR: 1.96; 95% CI 1.43-2.67. The oldest-old was at significantly increased risk of both being discharged to a skilled nursing facility or subacute rehabilitation (adjusted HR: 2.19; 95% CI 1.33-3.59) as well as of dying in the hospital (adjusted HR: 1.81; 95% CI 1.21-2.71). Conclusion:Previously home-dwelling oldest-old are at significantly increased risk of failing to return home immediately following medical ICU admission with IMV as compared to patients aged 50-70 years. These results can help medical ICU staff establish appropriate expectations when addressing the families of their oldest patients. Further studies are needed to evaluate the potential for delayed home return among the oldest old and to assess the ability of frailty indices to predict home return within this ICU population.

Project description:ObjectivesTo assess the reliability of codes relevant to critically ill patients in administrative data.DesignRetrospective cohort study linking data from Acute Physiology and Chronic Health Evaluation Outcomes, a clinical database of ICU patients with data from Medicare Provider Analysis and Review. We linked data based on matching for sex, date of birth, hospital, and date of admission to hospital.SettingForty-six hospitals in the United States participating in Acute Physiology and Chronic Health Evaluation Outcomes.PatientsAll patients in Acute Physiology and Chronic Health Evaluation Outcomes greater than or equal to 65 years old who could be linked with hospitalization records in Medicare Provider Analysis and Review from January 1, 2009, through September 30, 2012.Measurements and main resultsOf 62,451 patients in the Acute Physiology and Chronic Health Evaluation Outcomes dataset, 80.1% were matched with data in Medicare Provider Analysis and Review. All but 2.7% of Acute Physiology and Chronic Health Evaluation Outcomes ICU patients had either an ICU or coronary care unit charge in Medicare Provider Analysis and Review. In Acute Physiology and Chronic Health Evaluation Outcomes, 37.0% received mechanical ventilation during the ICU stay versus 24.1% in Medicare Provider Analysis and Review. The Medicare Provider Analysis and Review procedure codes for mechanical ventilation had high specificity (96.0%; 95% CI, 95.8-96.2), but only moderate sensitivity (58.4%; 95% CI, 57.7-59.1), with a positive predictive value of 89.6% (95% CI, 89.1-90.1) and negative predictive value of 79.7% (95% CI, 79.4-80.1). For patients with mechanical ventilation codes, Medicare Provider Analysis and Review overestimated the percentage with a duration greater than 96 hours (36.6% vs 27.3% in Acute Physiology and Chronic Health Evaluation Outcomes). There was discordance in the hospital discharge status (alive or dead) for only 0.47% of all linked records (κ = 1.00).ConclusionsMedicare Provider Analysis and Review data contain robust information on hospital mortality for patients admitted to the ICU but have limited ability to identify all patients who received mechanical ventilation during a critical illness. Estimates of use of mechanical ventilation in the United States should likely be revised upward.
