RESUMO
INTRODUCTION: In order to be positioned to address the increasing strain of burnout and worsening nurse shortage, a better understanding of factors that contribute to nursing workload is required. This study aims to examine the difference between order-based and clinically perceived nursing workloads and to quantify factors that contribute to a higher clinically perceived workload. DESIGN: A retrospective cohort study was used on an observational dataset. METHODS: We combined patient flow, nurse staffing and assignment, and workload intensity data and used multivariate linear regression to analyze how various shift, patient, and nurse-level factors, beyond order-based workload, affect nurses' clinically perceived workload. RESULTS: Among 53% of our samples, the clinically perceived workload is higher than the order-based workload. Factors associated with a higher clinically perceived workload include weekend or night shifts, shifts with a higher census, patients within the first 24 h of admission, and male patients. CONCLUSIONS: The order-based workload measures tended to underestimate nurses' clinically perceived workload. We identified and quantified factors that contribute to a higher clinically perceived workload, discussed the potential mechanisms as to how these factors affect the clinically perceived workload, and proposed targeted interventions to better manage nursing workload. CLINICAL RELEVANCE: By identifying factors associated with a high clinically perceived workload, the nurse manager can provide appropriate interventions to lighten nursing workload, which may further reduce the risk of nurse burnout and shortage.
RESUMO
Lung-protective ventilation strategies are the current standard of care for patients with acute respiratory distress syndrome in an effort to provide adequate ventilatory requirements while minimizing ventilator-induced lung injury. Some patients may benefit from ultra-lung-protective ventilation, a strategy that achieves lower airway pressures and Vt than the current standard. Specific physiological parameters beyond severity of hypoxemia, such as driving pressure and respiratory system elastance, may be predictive of those most likely to benefit. Because application of ultra-lung-protective ventilation is often limited by respiratory acidosis, extracorporeal membrane oxygenation or extracorporeal carbon dioxide removal, which remove carbon dioxide from blood, is an attractive option. These strategies are associated with hematological complications, especially when applied at low blood-flow rates with devices designed for higher blood flows, and a recent large randomized controlled trial failed to show a benefit from an extracorporeal carbon dioxide removal-facilitated ultra-lung-protective ventilation strategy. Only in patients with very severe forms of acute respiratory distress syndrome has the use of an ultra-lung-protective ventilation strategy-accomplished with extracorporeal membrane oxygenation-been suggested to have a favorable risk-to-benefit profile. In this critical care perspective, we address key areas of controversy related to ultra-lung-protective ventilation, including the trade-offs between minimizing ventilator-induced lung injury and the risks from strategies to achieve this added protection. In addition, we suggest which patients might benefit most from an ultra-lung-protective strategy and propose areas of future research.

Rationale: Two distinct subphenotypes have been identified in acute respiratory distress syndrome (ARDS), but the presence of subgroups in ARDS associated with coronavirus disease (COVID-19) is unknown. Objectives: To identify clinically relevant, novel subgroups in COVID-19-related ARDS and compare them with previously described ARDS subphenotypes. Methods: Eligible participants were adults with COVID-19 and ARDS at Columbia University Irving Medical Center. Latent class analysis was used to identify subgroups with baseline clinical, respiratory, and laboratory data serving as partitioning variables. A previously developed machine learning model was used to classify patients as the hypoinflammatory and hyperinflammatory subphenotypes. Baseline characteristics and clinical outcomes were compared between subgroups. Heterogeneity of treatment effect for corticosteroid use in subgroups was tested. Measurements and Main Results: From March 2, 2020, to April 30, 2020, 483 patients with COVID-19-related ARDS met study criteria. A two-class latent class analysis model best fit the population (P = 0.0075). Class 2 (23%) had higher proinflammatory markers, troponin, creatinine, and lactate, lower bicarbonate, and lower blood pressure than class 1 (77%). Ninety-day mortality was higher in class 2 versus class 1 (75% vs. 48%; P < 0.0001). Considerable overlap was observed between these subgroups and ARDS subphenotypes. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR cycle threshold was associated with mortality in the hypoinflammatory but not the hyperinflammatory phenotype. Heterogeneity of treatment effect to corticosteroids was observed (P = 0.0295), with improved mortality in the hyperinflammatory phenotype and worse mortality in the hypoinflammatory phenotype, with the caveat that corticosteroid treatment was not randomized. Conclusions: We identified two COVID-19-related ARDS subgroups with differential outcomes, similar to previously described ARDS subphenotypes. SARS-CoV-2 PCR cycle threshold had differential value for predicting mortality in the subphenotypes. The subphenotypes had differential treatment responses to corticosteroids.

BACKGROUND: Prevalence and etiology of unconsciousness are uncertain in hospitalized patients with coronavirus disease 2019 (COVID-19). We tested the hypothesis that increased inflammation in COVID-19 precedes coma, independent of medications, hypotension, and hypoxia. METHODS: We retrospectively assessed 3203 hospitalized patients with COVID-19 from March 2 through July 30, 2020, in New York City with the Glasgow Coma Scale and systemic inflammatory response syndrome (SIRS) scores. We applied hazard ratio (HR) modeling and mediation analysis to determine the risk of SIRS score elevation to precede coma, accounting for confounders. RESULTS: We obtained behavioral assessments in 3203 of 10,797 patients admitted to the hospital who tested positive for SARS-CoV-2. Of those patients, 1054 (32.9%) were comatose, which first developed on median hospital day 2 (interquartile range [IQR] 1-9). During their hospital stay, 1538 (48%) had a SIRS score of 2 or above at least once, and the median maximum SIRS score was 2 (IQR 1-2). A fivefold increased risk of coma (HR 5.05, 95% confidence interval 4.27-5.98) was seen for each day that patients with COVID-19 had elevated SIRS scores, independent of medication effects, hypotension, and hypoxia. The overall mortality in this population was 13.8% (n = 441). Coma was associated with death (odds ratio 7.77, 95% confidence interval 6.29-9.65) and increased length of stay (13 days [IQR 11.9-14.1] vs. 11 [IQR 9.6-12.4]), accounting for demographics. CONCLUSIONS: Disorders of consciousness are common in hospitalized patients with severe COVID-19 and are associated with increased mortality and length of hospitalization. The underlying etiology of disorders of consciousness in this population is uncertain but, in addition to medication effects, may in part be linked to systemic inflammation.

BACKGROUND: Over 40â000 patients with COVID-19 have been hospitalised in New York City (NY, USA) as of April 28, 2020. Data on the epidemiology, clinical course, and outcomes of critically ill patients with COVID-19 in this setting are needed. METHODS: This prospective observational cohort study took place at two NewYork-Presbyterian hospitals affiliated with Columbia University Irving Medical Center in northern Manhattan. We prospectively identified adult patients (aged ≥18 years) admitted to both hospitals from March 2 to April 1, 2020, who were diagnosed with laboratory-confirmed COVID-19 and were critically ill with acute hypoxaemic respiratory failure, and collected clinical, biomarker, and treatment data. The primary outcome was the rate of in-hospital death. Secondary outcomes included frequency and duration of invasive mechanical ventilation, frequency of vasopressor use and renal replacement therapy, and time to in-hospital clinical deterioration following admission. The relation between clinical risk factors, biomarkers, and in-hospital mortality was modelled using Cox proportional hazards regression. Follow-up time was right-censored on April 28, 2020 so that each patient had at least 28 days of observation. FINDINGS: Between March 2 and April 1, 2020, 1150 adults were admitted to both hospitals with laboratory-confirmed COVID-19, of which 257 (22%) were critically ill. The median age of patients was 62 years (IQR 51-72), 171 (67%) were men. 212 (82%) patients had at least one chronic illness, the most common of which were hypertension (162 [63%]) and diabetes (92 [36%]). 119 (46%) patients had obesity. As of April 28, 2020, 101 (39%) patients had died and 94 (37%) remained hospitalised. 203 (79%) patients received invasive mechanical ventilation for a median of 18 days (IQR 9-28), 170 (66%) of 257 patients received vasopressors and 79 (31%) received renal replacement therapy. The median time to in-hospital deterioration was 3 days (IQR 1-6). In the multivariable Cox model, older age (adjusted hazard ratio [aHR] 1·31 [1·09-1·57] per 10-year increase), chronic cardiac disease (aHR 1·76 [1·08-2·86]), chronic pulmonary disease (aHR 2·94 [1·48-5·84]), higher concentrations of interleukin-6 (aHR 1·11 [95%CI 1·02-1·20] per decile increase), and higher concentrations of D-dimer (aHR 1·10 [1·01-1·19] per decile increase) were independently associated with in-hospital mortality. INTERPRETATION: Critical illness among patients hospitalised with COVID-19 in New York City is common and associated with a high frequency of invasive mechanical ventilation, extrapulmonary organ dysfunction, and substantial in-hospital mortality.

OBJECTIVE: It is unknown how hospital- and systems-level factors have impacted patient safety in the intensive care unit (ICU) during the COVID-19 pandemic. We sought to understand how the pandemic has exacerbated preexisting patient safety issues and created novel patient safety challenges in ICUs in the United States. METHODS: We performed a national, multi-institutional, mixed-methods survey of critical care clinicians to elicit experiences related to patient safety during the pandemic. The survey was disseminated via email through the Society of Critical Care Medicine listserv. Data were reported as valid percentages, compared by COVID caseload and peak of the pandemic; free-text responses were analyzed and coded for themes. RESULTS: We received 335 survey responses. On general patient safety, 61% felt that conditions were more hazardous when compared with the prepandemic period. Those who took care of mostly COVID-19 patients were more likely to perceive that care was more hazardous (odds ratio, 4.89; 95% CI, 2.49-9.59) compared with those who took care of mostly non-COVID-19 or no COVID-19 patients. In free-text responses, providers identified patient safety risks related to pandemic adaptations, such as ventilator-related lung injury, medication and diagnostic errors, oversedation, oxygen device removal, and falls. CONCLUSIONS: Increased COVID-19 case burden was significantly associated with perceptions of a less safe patient care environment by frontline ICU clinicians. Results of the qualitative analysis identified specific patient safety hazards in ICUs across the United States as downstream consequences of hospital and provider strain during periods of the COVID-19 pandemic.

Rationale: Early mobilization of extracorporeal membrane oxygenation (ECMO)-supported patients is increasingly common, but it remains unknown whether there are factors predictive of achieving higher intensity mobilization among those able to participate in physical therapy. Additionally, data regarding the safety and feasibility of early mobilization with femoral cannulation, particularly ambulation, are sparse. Objectives: To determine whether there are factors associated with achieving out-of-bed versus in-bed physical therapy in ECMO-supported patients participating in physical therapy, and whether mobilization with femoral cannulation is safe and feasible. Methods: This large, single-center, retrospective study evaluated adult patients who performed active physical therapy while receiving ECMO. Mixed effects modeling was used to identify predictors of out-of-bed versus in-bed activity. Rates of mobilization with femoral cannulation and adverse events were also reported. Results: Between April 2009 and January 2020, 511 patients were supported with ECMO in a single medical intensive care unit, of whom 177 (35%) underwent active physical therapy and were included in the analysis, including 124 of 141 (88%) bridge to lung transplantation and 53 of 370 (14%) bridge to recovery. These 177 patients accounted for 2,706 active physical therapy sessions, with 138 patients (78%) achieving out-of-bed activity. In total, 108 (61%) patients ambulated (1,284 sessions), 34 of whom had femoral cannulae (250 sessions). Bridge-to-transplant (odds ratio [OR], 17.2; 95% confidence interval [CI], 4.12-72.1), venovenous ECMO (OR, 2.83; 95% CI, 1.29-6.22), later cannulation year (OR, 1.65; 95% CI, 1.37-1.98) and higher Charlson comorbidity index (OR, 1.53; 95% CI, 1.07-2.19) were associated with increased odds of achieving out-of-bed versus in-bed physical therapy, whereas invasive mechanical ventilation (OR, 0.11; 95% CI, 0.05-0.25) and femoral cannulation (OR, 0.19; 95% CI, 0.04-0.92) were associated with decreased odds of performing out-of-bed activities. Adverse events occurred in 2% of sessions. Conclusions: Several patient- and ECMO-related factors were associated with achieving higher intensity of early mobilization in patients participating in rehabilitation. Physical therapy with femoral cannulation was safe and feasible, and complications related to mobilization were uncommon.

RATIONALE: Studies suggest a pathogenic role of endothelial dysfunction in chronic obstructive lung disease (COPD). Omega-3 (n-3) polyunsaturated fatty acid (PUFA) supplementation improves endothelial function in other diseases but has not been examined in COPD. OBJECTIVE: We hypothesized that n-3 PUFA supplementation would improve systemic endothelial function in COPD. We performed a pilot randomized, placebo-controlled, double-blind, phase 2 superiority trial (NCT00835289). METHODS: Adults with moderate and severe stable COPD (79% with emphysema on computed tomography [CT]) were randomized to high-dose fish oil capsules or placebo daily for 6 months. The primary endpoint was percentage change in brachial artery flow-mediated dilation (FMD) from baseline to 6 months. Secondary endpoints included peripheral arterial tonometry, endothelial microparticles (EMPs), 6-minute walk distance, respiratory symptoms, and pulmonary function. RESULTS: Thirty-three of 40 randomized participants completed all measurements. Change in FMD after 6 months did not differ between the fish oil and placebo arms (-1.1%, 95% CI -5.0-2.9, p=0.59). CD31+ EMPs increased in the fish oil arm (0.9%, 95% CI 0.1-1.7, p=0.04). More participants in the fish oil arm reported at least a 4-point improvement in the St George's Respiratory Questionnaire (SGRQ) compared to placebo (8 versus 1; p=0.01). There were no significant changes in other secondary endpoints. There were 4 serious adverse events determined to be unrelated to the study (3 in the fish oil arm and 1 in the placebo arm). CONCLUSION: Randomization to n-3 PUFAs for 6 months did not change systemic endothelial function in COPD. Changes in EMPs and SGRQ suggest n-3 PUFAs might have biologic and clinical effects that warrant further investigation.
RESUMO
PURPOSE: Lung protective ventilation (LPV), defined as a tidal volume (Vt) ≤8 cc/kg of predicted body weight, reduces ventilator-induced lung injury but is applied inconsistently. MATERIALS AND METHODS: We conducted a prospective, quasi-experimental, cohort study of adults mechanically ventilated admitted to intensive care units (ICU) in the year before, year after, and second year after implementation of an electronic medical record based LPV order, and a cross-sectional qualitative study of ICU providers regarding their perceptions of the order. We applied the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate the implementation. RESULTS: There were 1405, 1424, and 1342 in the control, adoption, and maintenance cohorts, representing 95% of mechanically ventilated adult ICU patients. The overall prevalence of LPV increased from 65% to 73% (p < 0.001, adjusted-OR for LPV adherence: 1.9, 95% CI 1.5-2.3), but LPV adherence in women was approximately 30% worse than in men (women: 44% to 56% [p < 0.001],men: 79% to 86% [p < 0.001]). ICU providers noted difficulty obtaining an accurate height measurement and mistrust of the Vt calculation as barriers to implementation. LPV adherence increased further in the second year post implementation. CONCLUSION: We designed and implemented an LPV order that sustainably improved LPV adherence across diverse ICUs.

The coronavirus disease 2019 (COVID-19) pandemic has placed extraordinary strain on global healthcare systems. Use of extracorporeal membrane oxygenation (ECMO) for patients with severe respiratory or cardiac failure attributed to COVID-19 has been debated due to uncertain survival benefit and the resources required to safely deliver ECMO support. We retrospectively investigated adult patients supported with ECMO for COVID-19 at our institution during the first 80 days following New York City's declaration of a state of emergency. The primary objective was to evaluate survival outcomes in patients supported with ECMO for COVID-19 and describe the programmatic adaptations made in response to pandemic-related crisis conditions. Twenty-two patients with COVID-19 were placed on ECMO during the study period. Median age was 52 years and 18 (81.8%) were male. Twenty-one patients (95.4%) had severe ARDS and seven (31.8%) had cardiac failure. Fifteen patients (68.1%) were managed with venovenous ECMO while 7 (31.8%) required arterial support. Twelve patients (54.5%) were transported on ECMO from external institutions. Twelve patients were discharged alive from the hospital (54.5%). Extracorporeal membrane oxygenation was used successfully in patients with respiratory and cardiac failure due to COVID-19. The continued use of ECMO, including ECMO transport, during crisis conditions was possible even at the height of the COVID-19 pandemic.

BACKGROUND: Little is known about the actual treatment of patients with chronic obstructive pulmonary disease (COPD), either in the inpatient or outpatient settings. We hypothesized that there are substantial opportunities for improvement in adherence with current guidelines and recommendations. METHODS: We reviewed the medical records of all patients hospitalized with acute exacerbation of COPD between January 2005 and December 2006 at 5 New York City hospitals. RESULTS: There were 1285 unique patients with 1653 hospitalizations. Of these 1653, 83% were for patients with a prior history of COPD and 368 (22%) represented repeat admissions during our study period. The majority were treated during their hospitalization with a combination of systemic steroids (85%), bronchodilators (94%) and antibiotics (80%). There were 59 deaths (3.6%). Smoking cessation counseling was offered to 48% of active smokers. Influenza and pneumococcal vaccines were administered to half of eligible patients. On discharge, only 46.0% were prescribed maintenance bronchodilators and 24% were not prescribed any inhaled therapy. Even in the 226 unique patients (17.6%) readmitted at least once during course of the study, on discharge only 44.7% were prescribed maintenance bronchodilators and 23% were not prescribed any regular inhaled therapy. CONCLUSIONS: Patients hospitalized with acute exacerbation of COPD generally receive adequate hospital care, but there may be opportunities to improve care pharmacologically and with smoking cessation counseling and vaccination during and after hospitalization.

PURPOSE: The coronavirus disease 2019 (COVID-19) is associated with high rates of acute respiratory distress syndrome (ARDS). Prone positioning improves mortality in moderate-to-severe ARDS. Strategies to increase prone positioning under crisis conditions are needed. MATERIAL AND METHODS: We describe the development of a mobile prone team during the height of the crisis in New York City and describe characteristics and outcomes of mechanically ventilated patients who received prone positioning between April 2, 2020 and April 30, 2020. RESULTS: Ninety patients underwent prone positioning for moderate-to-severe ARDS. Sixty-six patients (73.3%) were men, with a median age of 64 years (IQR 53-71), and the median PaO2:FiO2 ratio was 107 (IQR 85-140) prior to prone positioning. Patients required an average of 3 ± 2.2 prone sessions and the median time of each prone session was 19 h (IQR 17.5-20.75). By the end of the study period, proning was discontinued in sixty-seven (65.1%) cases due to clinical improvement, twenty (19.4%) cases due to lack of clinical improvement, six (5.8%) cases for clinical worsening, and ten (9.7%) cases due to a contraindication. CONCLUSION: The rapid development of a mobile prone team safely provided prone positioning to a large number of COVID-19 patients with moderate-to-severe ARDS.

BACKGROUND: Delirium is a common, underdetected problem that has short- and long-term negative sequelae for critically ill patients. Prompt and accurate delirium identification by nurses can ensure early intervention and treatment to help minimize adverse outcomes. OBJECTIVES: To evaluate the relationship between an educational program and the accuracy of registered nurses' (RNs') documentation of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), a delirium screening tool. METHODS: In a medical ICU at a tertiary academic medical center from September 2015 to March 2016, RNs were reinstructed on use of the CAM-ICU. Registered nurse assessment data were collected retrospectively for 12 months before and after intervention and were compared against the CAM-ICU algorithm using χ analysis. RESULTS: A total of 10 736 RN assessments in 1020 patients preintervention and 11 068 in 951 patients postintervention were evaluated. Overall RN accuracy improved from 78% to 80% (P = .054). The algorithm determined delirium to be present in 32% versus 30% of all patients preintervention and postintervention, respectively; there was no difference in rate of nurse detection of delirium preintervention and postintervention (54% vs 55%, not statistically significant). The percentage of "inappropriate unable to assess" ratings by nurses decreased from 42% to 37% postintervention (P < .05). CONCLUSIONS: After a comprehensive training initiative, there was no significant improvement in CAM-ICU documentation and no improvements in patient delirium identification. Future quality improvement efforts should target reducing the number of assessments that RNs judge to be "unable to assess." Clinical practice must evolve to routinely incorporate RN delirium assessments into the patient's plan of care.

BACKGROUND: Nearly 30,000 patients with coronavirus disease-2019 (COVID-19) have been hospitalized in New York City as of April 14th, 2020. Data on the epidemiology, clinical course, and outcomes of critically ill patients with COVID-19 in this setting are needed. METHODS: We prospectively collected clinical, biomarker, and treatment data on critically ill adults with laboratory-confirmed-COVID-19 admitted to two hospitals in northern Manhattan between March 2nd and April 1st, 2020. The primary outcome was in-hospital mortality. Secondary outcomes included frequency and duration of invasive mechanical ventilation, frequency of vasopressor use and renal-replacement-therapy, and time to clinical deterioration following hospital admission. The relationship between clinical risk factors, biomarkers, and in-hospital mortality was modeled using Cox-proportional-hazards regression. Each patient had at least 14 days of observation. RESULTS: Of 1,150 adults hospitalized with COVID-19 during the study period, 257 (22%) were critically ill. The median age was 62 years (interquartile range [IQR] 51-72); 170 (66%) were male. Two-hundred twelve (82%) had at least one chronic illness, the most common of which were hypertension (63%; 162/257) and diabetes mellitus (36%; 92/257). One-hundred-thirty-eight patients (54%) were obese, and 13 (5%) were healthcare workers. As of April 14th, 2020, in-hospital mortality was 33% (86/257); 47% (122/257) of patients remained hospitalized. Two-hundred-one (79%) patients received invasive mechanical ventilation (median 13 days [IQR 9-17]), and 54% (138/257) and 29% (75/257) required vasopressors and renal-replacement-therapy, respectively. The median time to clinical deterioration following hospital admission was 3 days (IQR 1-6). Older age, hypertension, chronic lung disease, and higher concentrations of interleukin-6 and d-dimer at admission were independently associated with in-hospital mortality. CONCLUSIONS: Critical illness among patients hospitalized with COVID-19 in New York City is common and associated with a high frequency of invasive mechanical ventilation, extra-pulmonary organ dysfunction, and substantial in-hospital mortality.
RESUMO
Identifying patients at risk of deterioration in the hospital and intervening more quickly to prevent adverse events is a top patient safety priority. Early warning scores (EWS) identify at risk patients, but there is much opportunity for improvement particularly related to increasing lead time - the time from an alert trigger to adverse event (e.g., cardiac arrest, death). Our team develops healthcare process models of clinical concern (HPM-CC) and in this work has identified documentation signals that are proxies of nurses concern and can be used to predict patient risk earlier than current EWS systems that rely only on physiological data. We compared the performance of a validated EWS - the MEWS - to our novel model (MEWS-CC) comprised of MEWS criteria plus 3 proxy variables of nursing concern. MEWS-CC performed similarly to MEWS, with the added benefit of increased the time from EWS trigger to event by 5-26 hours.

The use of extracorporeal membrane oxygenation in the management of ARDS has grown considerably in the past decade, largely as a consequence of improvements in extracorporeal technology and management techniques. Recently published data has helped clarify the use of ECMO in ARDS, and its role in optimizing lung-protective ventilation and minimizing ventilator-induced lung injury has the potential to have a substantial impact on ARDS management and outcomes. In the future, novel extracorporeal management strategies may lead to a new paradigm in our approach to patients with ARDS.

INTRODUCTION: Survivors of critical illness face many potential long-term sequelae. Prior studies showed that early rehabilitation in the intensive care unit (ICU) reduces physical impairment and decreases ICU and hospital length of stay (LOS). However, these studies are based on a single ICU or were conducted with a small subset of all ICU patients. We examined the effect of an early rehabilitation program concurrently implemented in multiple ICUs on ICU and hospital LOS. METHODS: An early rehabilitation program was systematically implemented in five ICUs at the sites of two affiliated academic institutions. We retrospectively compared ICU and hospital LOS in the year before (1/2011-12/2011) and after (1/2012-12/2012) implementation. RESULTS: In the pre- and post-implementation periods, respectively, there were a total of 3945 and 4200 ICU admissions among the five ICUs. After implementation, there was a significant increase in the proportion of patients who received more rehabilitation treatments during their ICU stay (p < 0.001). The mean number of rehabilitation treatments per ICU patient-day increased from 0.16 to 0.72 (p < 0.001). In the post-implementation period, four of the five ICUs had a statistically significant decrease in mean ICU LOS among all patients. The overall decrease in mean ICU LOS across all five ICUs was 0.4 days (6.9%) (5.8 versus 5.4 days, p < 0.001). Across all five ICUs, there were 255 (6.5%) more admissions in the post-implementation period. The mean hospital LOS for patients from the five ICUs also decreased by 5.4% (14.7 vs. 13.9 days, p < 0.001). CONCLUSIONS: A multi-ICU, coordinated implementation of an early rehabilitation program markedly increased rehabilitation treatments in the ICU and was associated with reduced ICU and hospital LOS as well as increased ICU admissions.
RESUMO
RATIONALE: The determinants of immunoglobulin G (IgG) level and the risk of hypogammaglobulinemia (HGG) in patients with severe lung disease before and after lung transplantation are unknown. OBJECTIVES: We aimed to identify predictors of low IgG levels before and after lung transplantation. METHODS: We performed a retrospective cohort study of 40 consecutive lung transplant recipients at our center. Total IgG levels were measured before and serially after transplantation. Mild HGG was defined as IgG levels from 400-699 mg/dl; severe HGG was defined as IgG levels<400 mg/dl. MEASUREMENTS AND MAIN RESULTS: Before transplantation, six (15%) patients had mild HGG, and none had severe HGG. Patients with chronic obstructive pulmonary disease had lower IgG levels compared with patients with other diseases (independent of corticosteroid use and age; p=0.001) and an increased risk of mild HGG (p=0.005). The cumulative incidences of mild and severe HGG significantly increased after transplantation (58 and 15%, respectively, both p<0.04 compared with pretransplant prevalences). Lower pretransplant IgG level and treatment with mycophenolate mofetil were associated with lower IgG levels after transplantation (both p<0.05). Only lower pretransplant IgG levels were significantly associated with an increased risk of severe HGG after transplantation (p=0.02). CONCLUSIONS: Mild HGG is common in patients with severe chronic obstructive pulmonary disease, and the incidences of mild and severe HGG increase significantly early after lung transplantation. Baseline IgG levels and treatment with mycophenolate mofetil affect post-transplant IgG levels.
