Epidemiology, risk factors, and applicability of CDC definitions for healthcare-associated bloodstream infections at a level IV neonatal ICU.

OBJECTIVES: We studied the epidemiology of primary bloodstream infections (BSIs), secondary BSIs, and central line-associated BSIs (CLABSIs) and applicability of CDC definitions for primary sources of infection causing secondary BSIs in patients in the neonatal ICU. STUDY DESIGN: We classified healthcare-associated BSIs (HABSIs) as primary BSIs, secondary BSIs, and CLABSIs using CDC surveillance definitions and determined their overall incidence and incidence among different gestational age strata. We assessed the applicability of CDC definitions for infection sources causing secondary BSIs. RESULTS: From 2010 to 2019, 141 (32.7%), 202 (46.9%), and 88 (20.4%) HABSIs were classified as primary BSIs, secondary BSIs, and CLABSIs, respectively; all declined during the study period (all p < 0.001). Gestational age <28 weeks was associated with increased incidence of all HABSI types. CDC criteria for site-specific primary sources were met in 137/202 (68%) secondary BSIs. CONCLUSIONS: Primary and secondary BSIs were more common than CLABSIs and should be prioritized for prevention.

Timing is everything: Early do-not-resuscitate orders in the intensive care unit and patient outcomes.

BACKGROUND: The use of Do-Not-Resuscitate (DNR) orders has increased but many are placed late in the dying process. This study is to determine the association between the timing of DNR order placement in the intensive care unit (ICU) and nurses' perceptions of patients' distress and quality of death. METHODS: 200 ICU patients and the nurses (n = 83) who took care of them during their last week of life were enrolled from the medical ICU and cardiac care unit of New York Presbyterian Hospital/Weill Cornell Medicine in Manhattan and the surgical ICU at the Brigham and Women's Hospital in Boston. Nurses were interviewed about their perceptions of the patients' quality of death using validated measures. Patients were divided into 3 groups-no DNR, early DNR, late DNR placement during the patient's final ICU stay. Logistic regression analyses modeled perceived patient quality of life as a function of timing of DNR order placement. Patient's comorbidities, length of ICU stay, and procedures were also included in the model. RESULTS: 59 patients (29.5%) had a DNR placed within 48 hours of ICU admission (early DNR), 110 (55%) placed after 48 hours of ICU admission (late DNR), and 31 (15.5%) had no DNR order placed. Compared to patients without DNR orders, those with an early but not late DNR order placement had significantly fewer non-beneficial procedures and lower odds of being rated by nurses as not being at peace (Adjusted Odds Ratio namely AOR = 0.30; [CI = 0.09-0.94]), and experiencing worst possible death (AOR = 0.31; [CI = 0.1-0.94]) before controlling for procedures; and consistent significance in severe suffering (AOR = 0.34; [CI = 0.12-0.96]), and experiencing a severe loss of dignity (AOR = 0.33; [CI = 0.12-0.94]), controlling for non-beneficial procedures. CONCLUSIONS: Placement of DNR orders within the first 48 hours of the terminal ICU admission was associated with fewer non-beneficial procedures and less perceived suffering and loss of dignity, lower odds of being not at peace and of having the worst possible death.

Circulating cell death biomarker TRAIL is associated with increased organ dysfunction in sepsis.

BACKGROUND: In sepsis, there may be dysregulation in programed cell death pathways, typified by apoptosis and necroptosis. Programmed cell death pathways may contribute to variability in the immune response. TRAIL is a potent inducer of apoptosis. Receptor-interacting serine/threonine protein kinase-3 (RIPK3) is integral to the execution of necroptosis. We explored whether plasma TRAIL levels were associated with in-hospital mortality, organ dysfunction, and septic shock. We also explored the relationship between TRAIL and RIPK3. METHODS: We performed an observational study of critically ill adults admitted to intensive care units at 3 academic medical centers across 2 continents, using 1 as derivation and the other 2 as validation cohorts. Levels of TRAIL were measured in the plasma of 570 subjects by ELISA. RESULTS: In all cohorts, lower (<28.5 pg/ml) versus higher levels of TRAIL were associated with increased organ dysfunction (P ≤ 0.002) and septic shock (P ≤ 0.004). Lower TRAIL levels were associated with in-hospital mortality in 2 of 3 cohorts (Weill Cornell-Biobank of Critical Illness, P = 0.012; Brigham and Women's Hospital Registry of Critical Illness, P = 0.011; Asan Medical Center, P = 0.369). Lower TRAIL was also associated with increased RIPK3 (P ≤ 0.001). CONCLUSION: Lower levels of TRAIL were associated with septic shock and organ dysfunction in 3 independent ICU cohorts. TRAIL was inversely associated with RIPK3 in all cohorts. FUNDING: NIH (R01-HL055330 and KL2-TR002385).

Underdetection and Undertreatment of Dyspnea in Critically Ill Patients.

Rationale: Dyspnea is a common and distressing physical symptom among patients in the ICU and may be underdetected and undertreated. Objectives: To determine the frequency of dyspnea relative to pain, the accuracy of nurses and personal caregiver dyspnea ratings relative to patient-reported dyspnea, and the relationship between nurse-detected dyspnea and treatment. Methods: This was an observational study of patients (n = 138) hospitalized in a medical ICU (MICU). Nurses and patients' personal caregivers at the bedside reported on their perception of patients' symptoms. Measurements and Main Results: Dyspnea was assessed by patients, caregivers, and nurses with a numerical rating scale. Across all three raters, the frequency of moderate to severe dyspnea was similar or greater than that of pain (P < 0.05 for caregiver and nurse ratings). Personal caregivers' ratings of dyspnea had substantial agreement with patient ratings (κ = 0.65, P < 0.001), but nurses' ratings were not significantly related to patient ratings (κ = 0.19, P = 0.39). Nurse detection of moderate to severe pain was significantly associated with opioid treatment (odds ratio, 2.70; 95% confidence interval, 1.10-6.60; P = 0.03); however, nurse detection of moderate to severe dyspnea was not significantly associated with any assessed treatment. Conclusions: Dyspnea was reported at least as frequently as pain among the sampled MICU patients. Personal caregivers had good agreement with patient reports of moderate to severe dyspnea. However, even when detected by nurses, dyspnea appeared to be undertreated. These findings suggest the need for improved detection and treatment of dyspnea in the MICU.

Dying Patient and Family Contributions to Nurse Distress in the ICU.

RATIONALE: Caring for patients at the end of life is emotionally taxing and may contribute to burnout. Nevertheless, little is known about the factors associated with emotional distress in intensive care unit (ICU) nurses. OBJECTIVES: To identify patient and family factors associated with nurses' emotional distress in caring for dying patients in the ICU. METHODS: One hundred nurses who cared for 200 deceased ICU patients at two large academic medical centers in the Northeast United States were interviewed about patients' psychological and physical symptoms, their reactions to those patient experiences (e.g., emotional distress), and perceived factors contributing to their emotional distress. Logistic regression analyses modeled nurses' emotional distress as a function of patient symptoms and care. RESULTS: Patients' overall quality of death (odds ratio [OR], 3.08; 95% confidence interval [CI], 1.31-7.25), suffering (OR, 2.34; CI, 1.03-5.29), and loss of dignity (OR, 2.95; CI, 1.19-7.29) were significantly associated with nurse emotional distress. Some 40.5% (79 of 195) of nurses identified families' fears of patient death, and 34.4% (67 of 195) identified families' unrealistic expectations as contributing to their own emotional distress. CONCLUSIONS: Patients' emotional distress, physical distress, and perceived quality of death are associated with nurse emotional distress. Unrealistic family expectations for the patient may be a source of nurse emotional distress. Improving patients' quality of death, including enhancing their dignity, reducing their suffering, and promoting acceptance of an impending death among family members may improve the emotional health of nurses.
