The Usefulness of Virtual Reality in Symptom Management during Chemotherapy in Lung Cancer Patients: A Quasi-Experimental Study.

Background: Virtual reality (VR) emerges as a promising non-pharmacological intervention for managing symptoms and providing distraction during chemotherapy. This study aims to assess VR's effectiveness on cancer-related symptoms, vital signs, and the patients' perception of chemotherapy in lung cancer patients. Methods: A quasi-experimental study was conducted on 100 patients. Participants were allocated into an intervention group (n = 55), which experienced immersive VR, and a comparison group (n = 45), which received usual care. Data were collected through questionnaires and checklists, including feedback on the VR experience, pain, vital signs, and common cancer symptoms, assessed through the Edmonton Symptom Assessment Scale. Results: VR had a significant impact on reducing the perception of chemotherapy length. Patients reported high levels of satisfaction and tolerability. No adverse events were observed. VR did not have significant influence on pain intensity or vital signs. The only exceptions were oxygen saturation, where a significant difference (p = 0.02) was reported, and the perception of chemotherapy duration. Conclusions: As a non-pharmacological intervention, VR proves to be beneficial in minimizing the perceived length of chemotherapy sessions for lung cancer patients, enhancing their overall treatment experience. The intervention was found to be a safe, feasible, and well-accepted distraction technique. Future research should explore VR's potential effects on a wider range of symptoms and evaluate its impact on long-term outcomes.

Calibration of the PREdiction of DELIRium in ICu Patients (PRE-DELIRIC) Score in a Cohort of Critically Ill Patients: A Retrospective Cohort Study.

BACKGROUND: To predict delirium in intensive care unit (ICU) patients, the Prediction of Delirium in ICU Patients (PRE-DELIRIC) score may be used. This model may help nurses to predict delirium in high-risk ICU patients. OBJECTIVES: The aims of this study were to externally validate the PRE-DELIRIC model and to identify predictive factors and outcomes for ICU delirium. METHOD: All patients underwent delirium risk assessment by the PRE-DELIRIC model at admission. We used the Intensive Care Delirium Screening Check List to identify patients with delirium. The receiver operating characteristic curve measured discrimination capacity among patients with or without ICU delirium. Calibration ability was determined by slope and intercept. RESULTS: The prevalence of ICU delirium was 55.8%. Discrimination capacity (Intensive Care Delirium Screening Check List score ≥4) expressed by the area under the receiver operating characteristic curve was 0.81 (95% confidence interval, 0.75-0.88), whereas sensitivity was 91.3% and specificity was 64.4%. The best cut-off was 27%, obtained by the max Youden index. Calibration of the model was adequate, with a slope of 1.03 and intercept of 8.14. The onset of ICU delirium was associated with an increase in ICU length of stay (P < .0001), higher ICU mortality (P = .008), increased duration of mechanical ventilation (P < .0001), and more prolonged respiratory weaning (P < .0001) compared with patients without delirium. DISCUSSION: The PRE-DELIRIC score is a sensitive measure that may be useful in early detection of patients at high risk for developing delirium. The baseline PRE-DELIRIC score could be useful to trigger use of standardized protocols, including nonpharmacologic interventions.

Prevalence and risk factors of delirium in the intensive care unit: An observational study.

BACKGROUND: Several risk factors, such as age, alcohol abuse, dementia, and severe illness, can contribute to the development of delirium. However, limited information is available in the literature regarding the risk of delirium among surgical, trauma, neurological, and medical intensive care patients. AIM: To describe the prevalence of risk factors associated with delirium in intensive care units. DESIGN: This study used an observational design. METHODS: We enrolled 165 patients hospitalized in two intensive care units in Italy. Patients were first evaluated using the Prediction of Delirium model and were subsequently evaluated using the Intensive Care Delirium Screening Checklist; evaluation lasted a maximum of 5 days for each admitted patient after sedation. A logistic regression model was used to identify the prevalence and risk factors of delirium. RESULTS: The average age of the patients was 57.6 (SD = 18.3) years, and the patients were predominantly male (65.0%). The majority of patients had been subjected to trauma (38.8%); 37.6% had undergone general surgical interventions, and 23.6% had undergone medical interventions. Delirium occurred in 55.8% of the 165 patients. The risk of delirium was independently associated with coma (odds ratio = 10.6; 95% confidence interval, 3.08-39.9) and the Acute Physiology and Chronic Health Evaluation II score (odds ratio = 4.27; 95% confidence interval, 1.58-11.53). CONCLUSIONS: This study confirmed that coma and the Acute Physiology and Chronic Health Evaluation II score were non-modifiable risk factors for delirium. Further studies could categorize the different types of coma. Proper delirium management could limit the impact on the recovery of these patients, their autonomy, and their reintegration into the social and professional world. RELEVANCE TO CLINICAL PRACTICE: Delirium increases intensive care unit and hospital length of stay. Early identification and risk factor assessment by critical care nurses are considered the key factors in the treatment of delirium.

Dressings and Securement Devices of Peripheral Arterial Catheters in Intensive Care Units and Operating Theaters: A Systematic Review.

BACKGROUND: Hemodynamic monitoring, implemented by the placement of peripheral arterial catheters (PACs), is a characterizing aspect of the intensive care units. Peripheral arterial catheters can continually detect blood pressure and quickly conduct blood sampling. The use of PACs is generally considered safe, without serious complications. Currently, only 25% of the implanted catheters are actually subject to complications, including accidental removal, dislocation, occlusion, and infection. All of these complications arise from inadequate catheter stabilization at the level of the skin. This study aimed to summarize and describe the effectiveness and characteristics of dressings and securement devices for catheter stabilization. METHODS: A systematic review of literature from the following databases was conducted: MEDLINE, CINAHL, Cochrane, EMBASE, and OvidSP. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement to guide article selection and reporting. RESULTS: Herein 626 articles were referred, with 5 directly related to the topic under discussion. We found 3 studies that describe PAC failure and 4 about dislodgement. We described 6 types of dressings or securement devices and classified them into 3 categories for classifying PAC dressings or securement devices. These were detected and grouped as adhesive tissues, sutureless devices, and transparent polyurethane dressings. CONCLUSIONS: Current research indicates that transparent polyurethane dressings offer the most effective catheter stabilization, but adhesive tissues may constitute a valid alternative. However, there are limited high-quality studies about effective dressings and securement devices for PACs.
