Brief summary

Routine bedside-nurse delirium documentation agreed only moderately with structured expert assessments in the ICU, and adding clinical context improved accuracy.

What NurseJet pulled from the source

Across 1535 paired assessments in 279 critically ill adults, agreement between bedside nurses' routine ICDSC screening (score of 4 or higher) and trained researchers' CAM-ICU assessments was only moderate (Cohen's kappa 0.42). A model that combined the individual ICDSC components with mechanical ventilation status and admission SOFA score predicted expert-confirmed delirium well (AUC 0.87; F1 0.72 on cross-validation), and the plain pass/fail cutoff performed worst of the models tested.

Why this matters for nurses

Delirium is common and harmful in the ICU, and routine charted screens are what downstream teams and registries rely on. This may matter because a single pass/fail nurse score may not capture delirium as well as a structured expert assessment, so a borderline screen that drives sedation, mobility, or escalation decisions is best read alongside the whole clinical picture rather than as a standalone verdict.

Bedside takeaway

Be aware that routine pass/fail ICDSC charting agreed only moderately with expert delirium assessments, so a borderline screen reads best alongside the whole clinical picture, not as a standalone verdict.

Key takeaways

Agreement between routine nurse ICDSC documentation and researcher CAM-ICU was moderate (Cohen's kappa 0.42) across 1535 assessments in 279 patients.
A model combining ICDSC components with ventilation status and admission SOFA score discriminated delirium well (AUC 0.87; F1 0.72).
The simple validated cutoff alone performed worst; richer component-level detail improved accuracy.
Patients were critically ill adults with acute respiratory failure or sepsis in academic-hospital ICUs.

Practice implications

Score every ICDSC component deliberately instead of rushing to a single pass/fail number, and when a screen sits near the threshold, corroborate it with your own bedside picture of attention, fluctuation, and level of consciousness. Use complete, accurate delirium documentation to support ABCDEF/ICU Liberation discussions about lightening sedation and early mobility.

Limitations & cautions

This was a single health-system, academic-ICU sample focused on respiratory failure and sepsis, so it may not generalize to all units. The optimized model was only internally validated by cross-validation and has not been tested prospectively, so real-world bedside performance is unproven.

In a prospective self-controlled study of 42 awake mechanically ventilated ICU patients, closed-system suctioning was followed by a sharp rise in self-reported dyspnea that largely resolved within 5 minutes, and this worsening occurred even though oxygen saturation went up.

ICUAI summaryReview source

Research ArticleResearchWorkflowAI summary · original source linked below

Endotracheal suctioning is a routine airway care procedure in mechanically ventilated patients, but its immediate effect on how breathless patients feel has not been well quantified. In this prospective self-controlled observational study conducted from May to October 2025 in a tertiary ICU in Sichuan Province, China, awake mechanically ventilated adults with a Richmond Agitation-Sedation Scale score of 0 to +1 who required closed-system suctioning were enrolled. Dyspnea was assessed with the Dyspnea Visual Analog Scale (D-VAS, 0 to 10) before suctioning (T0), immediately after (T1), and 5 minutes after (T2), while peripheral oxygen saturation (SpO2) and heart rate were recorded at the same times. Fifty-three suctioning procedures from 42 patients were included. D-VAS scores rose from 2.8 plus or minus 1.9 at T0 to 6.4 plus or minus 2.1 at T1 (mean increase 3.6, 95 percent CI 3.1 to 4.1, P less than 0.001), then fell to 3.2 plus or minus 1.7 at T2 (P less than 0.001 versus T1). Dyspnea worsened in 92.5 percent of procedures at T1, and 15.1 percent had not returned to baseline at T2. Even though SpO2 rose from 97.2 plus or minus 2.1 percent to 99.1 plus or minus 1.3 percent at T1, dyspnea worsened substantially, pointing to a possible dissociation between oxygenation and subjective respiratory distress. The authors conclude that closed-system suctioning may cause clinically significant but transient worsening of dyspnea that appears independent of oxygenation, and that individual dyspnea assessment during routine suctioning warrants attention, while noting the study was a single-center convenience sample.

Key takeaways

Across 53 closed-system suctioning procedures in 42 awake ventilated ICU patients, self-reported dyspnea rose sharply immediately after suctioning (D-VAS 2.8 to 6.4, mean increase 3.6, P less than 0.001) and largely settled by 5 minutes (3.2).
Dyspnea worsened in 92.5 percent of procedures right after suctioning, and 15.1 percent had not returned to baseline 5 minutes later.
Oxygen saturation actually increased with suctioning (97.2 percent to 99.1 percent), yet patients still felt more breathless, suggesting SpO2 and subjective distress can move in opposite directions.
The authors call the worsening clinically significant but transient and recommend assessing individual patients' dyspnea during routine suctioning.

Why this matters on shift

Suctioning is one of the most frequent things ICU nurses do for ventilated patients, and it is easy to assume that a stable or rising oxygen saturation means the patient is comfortable. This study may matter for critical care nurses because it shows that awake ventilated patients can feel markedly more breathless right after suctioning even when their SpO2 improves.

Bedside takeaway

Worth knowing that in a small ICU study, closed-system suctioning caused a sharp but short-lived rise in patient-reported breathlessness even as oxygen saturation rose, so a good SpO2 may not mean an awake ventilated patient feels comfortable.

Nursing implications

For ICU nurses, the findings suggest watching for and, where possible, asking about breathlessness around suctioning rather than relying on the oxygen saturation number alone, since most patients in this study felt worse immediately afterward. Knowing the distress is usually brief but occasionally lingers can support brief reassurance and reassessment before assuming an awake ventilated patient is at ease.

Limitations & cautions

This was a single-center convenience sample of only 42 patients and 53 procedures, with no prospective sample size calculation and a one-dimensional dyspnea scale, so the estimates are preliminary. It enrolled only awake, lightly sedated patients able to self-report, so the findings may not apply to more deeply sedated patients, and confirmatory multicenter studies are needed.

Nursing in Critical Care (PubMed)Jul 1, 2026Research Article

In a quasi-experimental study of 60 ICU nurses, adding short text-message reminders to a training session significantly improved nurses' knowledge and performance in ventilator-associated pneumonia prevention compared with the training session alone.

Med-Surg ICUAI summaryReview source

Research ArticleResearchInfection ControlAI summary · original source linked below

Sixty intensive care unit nurses in Kermanshah, Iran attended a training session on ventilator-associated pneumonia (VAP) prevention and were randomly split into a 30-nurse intervention group and a 30-nurse control group. The intervention group received educational text messages with key points from the session every other day for two weeks; the control group received none. Most participants were women (n = 40, 66 percent), more than half were over 30 years old (n = 28, 53 percent), and most had less than 10 years of experience (n = 52, 86 percent). At pre-test the groups were similar, with mean knowledge scores of 21.1 plus or minus 2.9 (intervention) and 20.2 plus or minus 2.9 (control) and performance scores of 120.8 plus or minus 10.4 and 120.1 plus or minus 13.4. At post-test the SMS group scored significantly higher than the control group on knowledge (22.1 plus or minus 1.9 vs 20.2 plus or minus 1.5; p less than 0.001) and on performance (126.9 plus or minus 8.2 vs 120.8 plus or minus 9.7; p less than 0.02). The authors conclude that ongoing SMS reminders improved nurses' VAP-prevention knowledge and performance.

Key takeaways

Sixty ICU nurses were randomized to receive VAP-prevention text-message reminders every other day for two weeks (n = 30) or training alone (n = 30).
At post-test, the SMS group scored significantly higher than the control group on knowledge (22.1 vs 20.2; p less than 0.001) and performance (126.9 vs 120.8; p less than 0.02).
The two groups had similar knowledge and performance scores before the intervention.
The authors describe the reminders as a low-cost microlearning approach that can reinforce infection-prevention behaviours, including in resource-limited settings.

Why this matters on shift

Ventilator-associated pneumonia is a serious ICU infection, and sustaining nurses' prevention knowledge and bedside adherence after a single training session is a common challenge. This study may matter for nurses and educators because it tests a simple, low-cost reinforcement, brief text messages, and finds it improved both knowledge and performance over training alone.

Bedside takeaway

Worth knowing that in a small ICU study, adding brief text-message reminders after a training session significantly improved nurses' knowledge and performance on ventilator-associated pneumonia prevention compared with training alone.

Nursing implications

For ICU nurses and educators, the findings suggest that short, repeated text-message reminders after a training session can be a practical way to keep VAP-prevention steps front of mind and improve measured performance. Because the effect was seen over a two-week window in one setting, such reminders are best viewed as a supplement to established VAP-prevention bundles rather than a replacement.

Limitations & cautions

This was a single-center quasi-experimental study of only 60 nurses in one Iranian city, so the results may not generalise to other units or countries. Performance was measured with a questionnaire over a short two-week period, so the study does not show whether gains persisted longer term or whether they translated into lower VAP rates for patients.

In a prospective cohort at one 900-bed center, nasogastric tube-related pressure injuries were significantly more frequent on the internal medicine ward than in the ICU, an unexpected reversal the authors link to comorbidity burden, staffing ratios, and tube-fixation technique.

ICU Med-SurgAI summaryReview source

Research ArticleResearchAI summary · original source linked below

This prospective cohort study followed adults who had a nasogastric tube placed during or within four hours before admission to the ICU (88 patients) or internal medicine ward (48 patients) of a 900-bed medical center, monitoring daily for tube-related pressure injuries from July 2022 to July 2024. Contrary to the expectation that sicker ICU patients would fare worse, incidence was significantly lower in the ICU (4 patients; 0.47 per 100 patient-days) than on the internal medicine ward (13 patients; 3.02 per 100 patient-days; P < .001). Internal medicine ward patients had a higher Charlson Comorbidity Index (mean 7.7 vs 3.0; P = .02), and nasogastric tube fixation methods differed between the departments. The authors name comorbidity burden, nurse-to-patient ratios, and fixation technique as possible contributors that warrant further study.

Key takeaways

Nasogastric tube-related pressure injury incidence was significantly lower in the ICU (0.47 per 100 patient-days) than on the internal medicine ward (3.02 per 100 patient-days; P < .001).
Four of 88 ICU patients versus 13 of 48 internal medicine ward patients developed a tube-related pressure injury.
Internal medicine ward patients carried a higher comorbidity burden (Charlson index 7.7 vs 3.0; P = .02).
Nasogastric tube fixation methods differed between the two departments and are a suspected contributor.

Why this matters on shift

Medical device-related pressure injuries from nasogastric tubes are painful, largely preventable, and easy to overlook under the tape. This study may matter for nurses because it challenges the assumption that these injuries cluster in the ICU, pointing instead to comorbidity, staffing, and fixation technique as drivers that apply on any ward.

Bedside takeaway

Worth knowing that nasogastric tube-related pressure injuries were more common on the internal medicine ward than in the ICU (3.02 vs 0.47 per 100 patient-days), pointing to comorbidity, staffing, and tube fixation as drivers.

Nursing implications

For nurses on any unit with tube-fed patients, the findings reinforce routinely inspecting the skin under and around nasogastric tube fixation (nares and cheeks), rotating or adjusting securement to relieve pressure, and not assuming lower-acuity wards are low risk. Consistent, pressure-relieving fixation technique and regular skin checks may matter as much as patient acuity.

Limitations & cautions

This was a single-center study with a small sample (88 ICU and 48 internal medicine ward patients), so the counterintuitive finding may not generalize, and the authors flag comorbidity burden, nurse-to-patient ratios, and fixation technique as confounders needing further investigation. Patients with pre-existing facial injuries or wounds were excluded, and the observational design cannot establish why incidence differed between departments.
