The Potential Effect of Changing Patient Position on Snoring: A Systematic Review.

Approximately 45% of adults snore occasionally, and 25% snore regularly, with a higher prevalence in men and an increase among postmenopausal women due to hormonal changes. Snoring is a health concern linked to vascular disease and decreased quality of life for both snorers and their bed partners. Effective snoring treatment, which aims to reduce or eliminate the sound, is challenging and depends on factors like age, comorbidities, disease severity, and anatomical features. This review aims to provide a systematic overview of the current literature on the effects of positional therapy (PT) on snoring. Various devices facilitate PT, including anti-snoring pillows and vibration alarms. PT devices maintain head and neck alignment to keep airways open, while head of bed elevation (HOBE) solutions reduce upper airway collapses by elevating the head and trunk. Studies show that PT and HOBE reduce snoring by increasing airway cross-sectional area and decreasing closing pressure. Despite their benefits, these non-surgical treatments have limitations, such as discomfort in certain sleeping positions and intolerance to prolonged head elevation. While reducing snoring intensity is critical for health reasons, further comparative studies between the different devices are needed to enhance snoring management.

Self-care advice for patients after surgery for oesophageal cancer - a mixed-methods systematic review.

The aim of the literature review was to identify and synthesise research on self-care advice for oesophageal cancer survivors. A mixed-methods systematic review and synthesis of existing literature on the topic. Five databases were searched for studies providing information on self-care advice for survivorship after oesophageal cancer surgery, in English, with no time filter. The Critical Appraisal Skills Program was used to assess the risk of bias. Data were presented by textual descriptions and grouping of data. Among the 13 studies included in the review, five pieces of self-care advice were identified; reconstructing eating habits, bed-head elevation, health-promoting advice, monitoring symptoms and body functions, and involving family and friends. The self-care advice was experienced to be hard work, but worth the effort. They also provided reassurance and an increased understanding of bodily changes and social consequences of the disease and treatment. Thereare is little evidence-based self-care advice for oesophageal cancer survivors. However, the existing self-care advice was appreciated and contributed to an increased understanding of the situation. Comprehensible and easy-to-follow recommendations should be provided to all oesophageal cancer survivors. Evidence-based self-care advice helpful for the individual oesophageal cancer survivor may be imperative to cope with the consequences of oesophagectomy after hospital discharge.

Inter-device agreement of sacral subepidermal oedema measurement in healthy adults during prolonged 60° head of bed elevation.

To investigate the level of agreement between the SEM 200 and Provisio® subepidermal moisture sacral delta measurements, which may indicate increased pressure injury risk, in healthy adults during 120 min of prolonged 60° head of bed elevation. This position, which requires the elevation of the patient's upper body at a 60° angle above the horizontal plane for an extended period, is used by clinicians to prevent or manage a patient's medical or surgical conditions. This prospective exploratory study recruited 20 healthy adults during October 2021 and collected sacral subepidermal moisture delta measurements using the SEM 200 and Provisio® devices. Delta measurements were taken at 20-min intervals over 120 min resulting in seven data collection timepoints. Descriptive statistics and a Bland Altman plot analysis were conducted. A total of 280 sacral subepidermal moisture delta measurements were gathered or 140 per device. There were good levels of agreement between the two devices at baseline (T0) [mean 0.025; SD 0.137] and following 60- (T3) [mean 0.025; SD 0.111], 80- (T4) [mean -0.01; SD 0.177] and 100 min (T5) [mean 0.01; SD 0.129] of prolonged 60° head of bed elevation. Head of bed elevations can increase a patient's risk of sacral pressure injuries. In some countries, nurses have access to the SEM 200 and/or the Provisio® device, so our findings may increase nurses' confidence in the interchangeability of the device measurements, although further research is needed to confirm this. The SEM 200 and Provisio® subepidermal moisture scanners show promise in gathering similar objective pressure injury risk data which could prompt clinicians to implement prevention strategies. Current pressure injury risk assessment is largely subjective in nature. This quantitative study on healthy human sacral tissue found a good level of agreement in the SEM 200 and Provisio® subepidermal moisture scanners, which may increase nurses' confidence in the interchangeability of the devices in clinical practice.

Ventilator-Associated Pneumonia in the Neonatal Intensive Care Unit—Incidence and Strategies for Prevention

The second most prevalent healthcare-associated infection in neonatal intensive care units (NICUs) is ventilator-associated pneumonia (VAP). This review aims to update the knowledge regarding the incidence of neonatal VAP and to summarize possible strategies for prevention. The VAP incidence ranges from 1.4 to 7 episodes per 1000 ventilator days in developed countries and from 16.1 to 89 episodes per 1000 ventilator days in developing countries. This nosocomial infection is linked to higher rates of illness, death, and longer hospital stays, which imposes a substantial financial burden on both the healthcare system and families. Due to the complex nature of the pathophysiology of VAP, various approaches for its prevention in the neonatal intensive care unit have been suggested. There are two main categories of preventative measures: those that attempt to reduce infections in general (such as decontamination and hand hygiene) and those that target VAP in particular (such as VAP care bundles, head of bed elevation, and early extubation). Some of the interventions, including practicing good hand hygiene and feeding regimens, are easy to implement and have a significant impact. One of the measures that seems very promising and encompasses a lot of the preventive measures for VAP are the bundles. Some preventive measures still need to be studied.

The effect of prolonged 60° head of bed elevation on sacral subepidermal oedema in healthy adults: A quantitative prospective exploratory study.

Head of bed elevation is used to manage some medical and surgical conditions however this may increase a patient's risk of sacral pressure injuries. Novel point-of-care technologies that measure subepidermal moisture can identify changes in localised subepidermal oedema and potential pressure injury risk. This prospective exploratory study investigated variations in sacral subepidermal oedema in healthy adults during 120-min of 60° head of bed elevation. Sacral subepidermal oedema was measured at 20-min intervals using the Provisio® subepidermal moisture scanner. Descriptive analysis, one-way repeated measures analysis of variance and an independent t-test were conducted. Slightly more male volunteers (n = 11; 55%) were recruited and the sample mean age was 39.3 years (SD 14.7) with an average body mass index of 25.8 (SD 4.3). Little variation in the mean sacral subepidermal moisture of healthy adults was observed. There was a statistically significant difference in the mean sacral subepidermal moisture measurements between males and females (Mean difference 0.18; 95% confidence intervals: 0.02 to 0.35; P = .03). Healthy adults can tolerate prolonged 60° head of bed elevation without developing increased subepidermal sacral oedema. This warrants further investigation in other populations, in various positions and over different time periods.

Safe to Sleep in Tennessee: A Statewide Quality Improvement Initiative.

Sleep-related deaths were the fourth leading cause of infant death in Tennessee between 2014 and 2018. In response, the Tennessee Initiative for Perinatal Quality Care developed a statewide quality improvement project, which focused on the demonstration and enforcement of a safe sleep environment in participating birthing hospitals to help families learn and practice the same at home. The project's aim was to improve the percent of infants audited for safe sleep practices (0-12 mo of age, cared for in participating newborn nurseries or neonatal intensive care units) that were compliant with the practices recommended by the 2016 American Academy of Pediatrics (AAP) Task Force on Sudden Infant Death Syndrome. Participating teams were required to develop and implement safe sleep policies in compliance with the AAP recommendations, provide safe sleep education to staff and families, and complete monthly safe sleep audits. A tool was provided to assess whether each audited infant was compliant with safe sleep recommendations and any reason(s) the infant was not compliant. Teams met virtually for monthly huddles and semiannual learning sessions to discuss the development and testing of change ideas. The project teams were able to improve the percent of infants audited that were compliant with safe sleep recommendations by 22% over the course of the project. Audits revealed the main reasons for noncompliance were additional objects in the crib (49%, 329/671), unsafe bedding (27%, 181/671), and head of bed elevation (24%, 164/671). This project demonstrates the positive impact that a statewide quality improvement initiative can have on identifying and addressing barriers, sharing resources and education, and monitoring local and statewide data, which led to increased compliance with safe sleep recommendations in the hospital. Safe sleep education and monitoring should be ongoing as new parents and staff always need to be educated on safe sleep principles. · In 2020, 25% of all infant deaths in Tennessee were due to an unsafe sleep environment.. · Sleep-related deaths in infants are frequently preventable.. · State quality improvement projects are effective in increasing safe sleep compliance.. · State perinatal quality collaboratives can partner with their State Department of Health, local hospitals, and providers, to increase awareness, educate parents, and model a safe sleep environment..

A Meta-analysis of the Clinical Efficacy of the Head-of-Bed Elevation for Patients With Acquired Brain Injury.

BACKGROUND: Acquired brain injury is caused by traumatic or nontraumatic factors and causes changes in cognition. Several reviews have described the influence of the head-of-bed (HOB) elevation on clinical indexes such as intracranial pressure (ICP) and cerebral perfusion pressure (CPP). However, the conclusions were inconsistent. Therefore, we aimed to evaluate the effects of HOB elevation in the care of the patients with ABI. METHODS: Two researchers independently screened the literature and extracted data. We searched PubMed, EMBASE, the Cochrane Library, Web of Science, and the Chinese Biological Literature Database to collect eligible randomized controlled trials published after September 2021. Reporting quality and methodological quality of the included studies were assessed by using the Preferred Reporting Items for Systematic Reviews and Meta-analysis and the Cochrane risk-of-bias tool. RESULTS: Eight studies were included in the meta-analysis. The results showed that, compared with the flat position, HOB elevation of 30° or 45° can significantly reduce ICP (mean difference [MD], -2.40 mm Hg; 95% confidence interval [CI], -3.19 to -1.61; P < .00001). However, there were no statistical differences in CPP (MD, -1.09; 95% CI, -3.93 to 1.75; P = .45), degree of disability at 90 days (relative risk, 1.01; 95% CI, 0.94-1.08; P = .83), and mean arterial pressure (MD, -0.44; 95% CI, -10.27 to 9.93; P = .93). CONCLUSION: Head-of-bed elevation of 30° can reduce ICP and maintain CPP, and may be an effective noninvasive nursing practice for the prognosis and rehabilitation of ABI patients. Owing to the lack of high-quality, large-sample randomized controlled trials, more rigorous trials are needed to support this conclusion.

The effect of head of bed elevation on sacral and heel subepidermal moisture in healthy adults: A randomised crossover study

BackgroundSubepidermal moisture (SEM) changes may detect early tissue injury and enhance pressure injury risk assessments. However, little is known how modifiable factors, like head of bed elevation (HOBE), affect SEM. AimThis study investigated the influence of HOBE on sacral and heel SEM, using the Provizio ® SEM Scanner. MethodA 2 × 2 randomised crossover study compared the effects of 30-min of 30⁰ versus 60⁰ HOBE on sacral and heel SEM in healthy adults. Results48 participants were randomly allocated to 30⁰ or 60⁰ HOBE and crossed over after a 60-min washout period. The mean age was 40.6 years (SD = 18.3). The study found the sacral and heel SEM values were not statistically different at 30⁰ versus 60⁰ HOBE. No clinically relevant association between SEM and characteristics of age, sex, body mass index and skin type were found. Baseline sacral and heel SEM values recovered after a 60-min washout period. Notably, half of the initial baseline measures suggested pressure injury risk. ConclusionThe HOBE may not influence SEM at the sacrum and heels, in healthy adults after 30 min of loading. Standard operating procedures for measuring SEM for pressure injury risk assessment require a stronger body of evidence in varied populations and timeframes before this technology is widely adopted.

Optimising the measurement of intra-bladder pressure in patients with predicted severe acute pancreatitis

BackgroundMeasuring intra-abdominal pressure (IAP) is important for management of patients with severe acute pancreatitis (SAP). Intra-bladder pressure (IBP) is an indirect index that reflects IAP, but measuring techniques vary. We sought to optimise IBP measuring techniques in predicted SAP patients. MethodsPredicted SAP patients consecutively admitted between June 2018 and January 2020 were scrutinised. Eligible patients had their IBP monitored for the first 72 h at 6-h intervals, and were then sequentially allocated into three research scenarios: (1) in the supine position along with head of bed elevation(HoBE)of 0, 15 and 30° at various points including the iliac crest the midaxillary line, pubic symphysis, and right atrium level, instilled with 25 mL normal saline (NS) at room temperature (RT); (2) NS instillation volume from 0, 10, 25, 40–50 mL at the iliac crest with HoBE15 at RT; and (3) NS instillation (25 mL) at either RT or 37 °C with HoBE15. ResultsThe dynamic IBP values measured at the pubic symphysis and iliac crest were fairly similar between HoBE0 and HoBE15 (all P > 0.05), but greatly increased at HoBE30 (all P < 0.01). IBP was significantly increased with escalating instillation volumes of NS (all P < 0.01 versus 0 mL NS), while there was no significant difference between 25 mL and 10 mL (P = 0.055). IBP was similar between NS at RT and under 37 °C (P = 0.643). ConclusionIn predicted SAP patients, measuring IBP at the iliac crest with HoBE15 after instilling 10 mL of NS seems to be appropriate for monitoring IAP.

Adherence to Head-of-Bed Elevation in Traumatic Brain Injury: An Audit

Abstract Background An important factor affecting the outcome of traumatic brain injury (TBI) is the early management of raised intracranial pressure (ICP). Head-of-bed elevation (HBE) is a simple and effective method to reduce ICP and prevent aspiration in head injury. Methods This audit was carried out in a level one trauma center. All adult TBI patients were included in the study except patients who had relative contraindication to HBE, managed in prone or Trendelenburg position or who were able to be seated themselves. Patients were observed twice daily, to check adherence to HBE. Adequate HBE angle was referred as an angle of 20 to 30 degrees. A digital protractor was used to measure the head-end angle. Following the first audit cycle, after discussion with nursing staff, a bedside checklist was formulated and two postintervention audit cycles were carried out. Results The first cycle showed that 40.35% of patients had inadequate HBE. Following implementation of the checklist, this percentage dropped to 11.27 and 7.5% in the second and third cycles, respectively. Agitation (p-value = 0.038) and Glasgow coma scale at admission (p-value = 0.028) were found to be confounders for adherence to HBE. Conclusion Agitation among mild and moderate TBI patients contributed to noncompliance for HBE. There was an increasing trend in adherence to maintaining adequate HBE following the use of a bedside checklist. Sustainability of improvement was confirmed with third audit cycle.

Effect of the head of bed elevation on back pain after elective coronary angiography: A randomized controlled trial

BackgroundPatients are restricted to bed and required to lie flat after coronary angiography (CAG) due to potential risk of vascular complications. This often causes back pain. AimWe aimed to investigate the effect of the head of bed (HOB) elevation on back pain and vascular complications after elective CAG. MethodsThree hundred and seven consecutive patients who underwent elective CAG were randomized into three groups. One control (HOB: 0 degree-flat position) and two experimental (HOB: 15 and 30 degrees) groups were compared. Back pain level was assessed using a visual analog scale. ResultsMean age was 58.1±10.7, and 59.9% (n=184) of the patients were males. Pain level at the 3rd hour and at the 6th hour was significantly higher in the control group than in the experimental groups. In the post-hoc analysis, pain level was significantly higher in HOB 15 degrees compared to that in HOB 30 degrees. In the multivariate analysis, HOB elevation to 30 degree was the only independent predictor of the pain level at the 3rd hour and the 6th hour. Only one patient in the HOB 0 degree group had a minor bleeding at the access site ConclusionsElevation of the HOB to 30 degrees was associated with decreased back pain level without increased risk of vascular complications.

A Comparative Study of 2-Hour Interface Pressure in Different Angles of Laterally Inclined, Supine, and Fowler's Position.

Insufficient research exists for position change intervals to eradicate pressure ulcers. We tried to provide evidence for the position change interval by comparing peak pressure, risk area ratio, and the time to reach 30 mmHg and 60 mmHg, and presented this in detail, according to the angle in the three positions. The study conducted RCTs on a total of 64 healthy adults. For two hours, interface pressure measurements were compared with 30° and 90° tilting at the inclined, 0° and 45° head-of-bed (HOB) elevation at the supine, and 30° and 45° HOB elevation at the Fowler’s position. The peak pressure on 30° tilting remained less than 60 mmHg for 2 h, unlike 90° tilting. To reach 60 mmHg took 78.18 min at 30° tilting, within 30 min at the 30° supine, 30° and 45° at the Fowler’s position, and 39.55 min at 0° supine. The pressure difference according to the angles was only significant at 30° and 90° tilting, with no difference in the other groups. To prevent pressure ulcers, position changes are required every 2 h in the 30° tilting position, every 1.5 to 2 h at 0° supine, and at least every 1.5 h for all the other positions.

Reducing Symptomatic Postoperative Hypotension in the Extended Stay Patient

<h3>Introduction</h3> Postoperative patients can exhibit hypotension secondary to anesthesia and blood loss. Patients that are on bedrest for an extended period are more at risk for orthostatic hypotension. These factors can contribute to a higher incidence of hypotensive symptoms when first mobilizing. Orthostatic hypotensive episodes can potentially lead to an increased risk for falls, reduced patient satisfaction, and delayed discharge. <h3>Identification of the Problem</h3> There is a higher rate of patients who exhibit hypotensive symptoms in the Overnight Stay Unit where patients are often on bedrest for extended periods. <h3>Purpose of the Study</h3> To form a quality improvement plan to reduce the incidence of hypotensive symptoms when mobilizing postoperative patients. <h3>Methods</h3> Data was collected over a 3-month period on 156 overnight stay and extended stay patients. Data tracked blood pressures, hypotensive symptoms, along with variables that nurses observed to affect this patient population's incidence of the negative symptoms. These included treating hypotension with an intravenous bolus, raising the head of bed, and assuring patients eat prior to mobilization. <h3>Results</h3> Data confirmed that most postoperative patients had a lower blood pressure than preoperatively, indicating that all patients are at risk for orthostatic hypotension and related symptoms. Data also supported the proposed theory that patients whose head of bed was elevated and who ate prior to mobilization were less likely to experience symptomatic hypotension. <h3>Discussion</h3> The study was limited because the preventive variables of intravenous bolus, head of bed elevation and eating prior to mobilization were implemented before the study began to give all patients the opportunity for optimal outcomes. <h3>Conclusion</h3> Staff was educated on postoperative patients' risk for hypotensive episodes. An improvement plan was implemented to optimize patient safety, patient sense of well-being and satisfaction, along with timely discharge. The plan includes assuring adequate hydration, verifying the patient has eaten, and elevating the head of the bed greater than 60 degrees at least 30 minutes prior to mobilization. <h3>Implication for Perianesthesia Nurses and Future Research</h3> Findings from this study can be a guide on actions perianesthesia nurses can perform to promote the best outcomes for mobilizing postoperative patients in extended stay areas.

Low FODMAPs diet or usual dietary advice for the treatment of refractory gastroesophageal reflux disease: An open-labeled randomized trial.

The low FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols) diet improves lower gastrointestinal symptoms. Patients suffering from proton pump inhibitor (PPI) refractory gastroesophageal reflux disease (GERD) have limited treatment options. We investigated the efficacy of a low FODMAPs diet in patients with PPI refractory GERD. This multicenter, randomized, open-label study compared the efficacy of a 4-week low FODMAPs diet and usual dietary advice (ie, low-fat diet and head of bed elevation) in patients with symptomatic PPI refractory GERD, defined by a Reflux Disease Questionnaire (RDQ) score >3 and abnormal pH-impedance monitoring on PPIs. The primary endpoint was the percentage of responders (RDQ ≤3) at the end of the diet. Thirty-one patients (55% women, median age 45years) were included, 16 randomized in the low FODMAPs diet group and 15 in the usual dietary advice group. Adherence to the assigned diet was good, with a significant difference in the FODMAPs intake per day between the low FODMAPs diet (2.5g) and the usual dietary advice group (13g) (p<0.001). There was no difference in response rates (RDQ score ≤3) between the low FODMAPs diet (6/16, 37.5%) and usual dietary advice (3/15, 20%) groups (p=0.43). Total RDQ score and dyspepsia subscore decreased significantly over time in both groups (p=0.002), with no difference according to the assigned diet group (p=0.85). Low FODMAPs diet and usual dietary advice have similar but limited beneficial effects on symptoms in patients with PPI refractory GERD.

Role of head-of-bed elevation in preventing ventilator-associated pneumonia bed elevation and pneumonia.

Elevating the head of bed (HOB) to 30° to 45° is an evidence-based recommendation to prevent ventilator-associated pneumonia (VAP). However, the available scientific data are inconclusive regarding the optimal degree of HOB elevation which is safe and effective for mechanically ventilated patients. To investigate the impact a of semirecumbent position at 30° and 45°on the development of VAP as compared with aHOB elevation to <30°. A 5-day, single centre, prospective, randomized, controlled, parallel group, three-arm study was conducted in adult patients on mechanical ventilation staying in the intensive care unit. Patients were randomly placed in <30°, 30°, or 45° HOB elevation position on the day of intubation and followed up for 5 days. They were assessed in terms of the development of microbiologically confirmed VAP (by the culture of endotracheal aspirate) over the study period. Sixty patients (20 in each arm) completed the study. VAP occurred in 55%, 25%, and 20% of patients in the HOB elevation to <30°, 30°, and 45°study arms, respectively. The frequency of VAP was significantly lower in the 45° compared with the <30° study arm (P=.022); there were no significant differences between the <30° and 30° as well as the 45° and 30° study groups. Unlike the frequency of VAP, the timing of the VAP (early or late) was not dependent on the degree of HOB elevation (P=.703). Keeping the mechanically ventilated patients in a semirecumbent position as close to 45°as possible should be the goal to prevent the development of VAP. The backrest elevation <30° should be avoided unless medically indicated. The study results reaffirm the crucial role of patient positioning, an essential nursing care intervention, in preventing VAP. Intensive care nurses can contribute to improving the VAP rates and outcomes by placing and keeping the patients in the correct position.

Body pressure prediction for pressure ulcer prevention in a bed head elevation operation

ABSTRACT Pressure ulcers are caused by tissue damage, which occurs when the blood supply to an area of skin is diminished because of sustained or concentrated pressure on a patient from the mattresses of a bed. One action that concentrates the pressure is a bed head elevation operation. Recently, a control system known as the alternative pressure mattress has been proposed to prevent the concentration of pressure. However, the challenge with this controlled system is that it has a slow response because it uses air cells. The slow response causes controlling the air cells to lag behind the change in pressure during the bed head elevation operation. Therefore, this system cannot adequately prevent the concentration of pressure on a patient. To address this issue, we need to predict the change in pressure during the bed head elevation operation and control the pressure based on this prediction. In the current work, we focus on predicting the pressure distribution. This prediction is high-dimensional. We regarded the pressure distribution as an image and predicted the change in pressure by applying a deep neural network. To the best of our knowledge, this paper is the first to propose the body pressure predictive model.

The effect of patient positioning on ultrasound landmarking for cricothyrotomy.

Our primary objective was to assess the difference in position of the ultrasound-guided landmark of the cricothyroid membrane (CTM) when performed with the supine patient positioned at different head of bed (HOB) elevations. In this prospective observational study of patients presenting to the emergency department with non-life-threatening complaints, subjects underwent ultrasound-guided landmarking of the CTM with HOB elevation at 0°, 30°, and 90°. A linear mixed effects regression model was used to assess the change in the CTM landmark associated with head position. We used a second adjusted linear mixed effects model to assess possible confounding patient factors associated with these changes. One-hundred and ten patients were enrolled, with a median [interquartile range] age of 39 [29-59] yr and 51:49 female:male ratio. Head of bed elevation at 30° and 90° resulted in a cephalad change in the CTM landmark of 2.7 mm (99% confidence interval [CI], 1.7 to 3.8; P < 0.001) and 4.2 mm (99% CI, 3.2 to 5.3; P < 0.001) respectively compared with the landmark at 0°. Body mass index (BMI) was associated with a change of 4.6 mm (99% CI, 0.5 to 8.7; P = 0.004) for BMI ≥ 30 compared with < 18.5 kg·m-2 The impact of patient age on distance depended on HOB elevation, where patients > 70 yr had a change of 2.6 mm (99% CI, 0.01 to 5.1; P = 0.009) at 90° HOB elevation compared with 30°. The location of the ultrasound-identified surface landmark of the CTM moves in a cephalad direction by changing the position of the HOB from supine 0° to elevation at 30° and 90°. This may be clinically important when attempting cricothyrotomy using a percutaneous (blind) technique, particularly when CTM identification and cricothyrotomy are performed at different head elevations.

Ventilation bundle compliance in two Australian intensive care units: An observational study

BackgroundThe ventilation bundle has been used in adult intensive care units to decrease harm and improve quality of care for mechanically ventilated patients. The ventilation bundle focuses on prevention of specific complications of mechanical ventilation; ventilator-associated pneumonia, sepsis, barotrauma, pulmonary oedema, pulmonary embolism, and acute respiratory distress syndrome. The Institute for Healthcare Improvement ventilation bundle consists of five structured evidence-based interventions: head of the bed elevation at 30–45°; daily sedation interruptions and assessment of readiness to extubate; peptic ulcer prophylaxis; deep vein thrombosis prophylaxis; and daily oral care with chlorhexidine. ObjectivesThe objective of the study was to evaluate the use of the ventilation bundle in two intensive care units in Victoria, Australia. MethodsThis is a 3-month prospective observational study in two intensive care units. Patient medical records were reviewed on days 3, 4, and 5 of mechanical ventilation using a prevalidated ventilation bundle checklist. ResultsA total of 96 critically ill patients required mechanical ventilation for more than 2 d. Patients had a mean age of 64.50 y (standard deviation = 14.89), with an Acute Physiology, Age, Chronic Health Evaluation (APACHE) III mean score of 79.27 (standard deviation = 27.11). The mean ventilation bundle compliance rate was 88.3% on the three consecutive mechanical ventilation days (day 3 = 79.4%, day 4 = 91.1%, and day 5 = 96.7%). There was a statistically significant difference in the mean APACHE III score between patients who had head of bed elevation and those without head of bed elevation, on days 3 (p = <0.001) and 4 (p = 0.007). ConclusionThe ventilation bundle elements were used in Australian intensive care units. The likelihood of having all ventilation bundle elements on day 3 was low if the patient's APACHE III score was high. However, the ventilation bundle compliance rate increased with mechanical ventilation days.

A Successful Bundled Intervention to Reduce Hospital-Acquired Pneumonia: Sustainability Still an Issue

Background: Hospital-acquired pneumonia (HAP) is one of the most common healthcare-associated infections (HAIs). Interventions based on the identification of patients at risk for aspiration with subsequent application of multidisciplinary measures, such as speech therapy follow-up, head elevation, oral hygiene, and patient and family education can be effective in reducing the incidence of HAP. In 2016, the step-down unit of our institution experienced an increase in the incidence of HAP with 21 cases. A root-cause analysis showed that most of them were related to comorbidities that increased aspiration risk. We conducted an study to decrease the incidence of HAP through a multidisciplinary bundled intervention. Methods: We conducted a quasi-experimental study in a 45-bed step-down unit from January 2016 to June 2019. In January 2017, we conducted an educational intervention with all the unit team, reinforcing practices of bed head elevation and oral hygiene. In June 2018, we observed inconsistencies in practice and conducted a second intervention with another round of educational training and a bundled intervention consisting of the following elements: identification of patients at risk for aspiration at admission by a speech therapy evaluation, bed-head elevation, oral hygiene, feeding guidance individualized to each patient by a nutritionist and a speech therapist, patient and family education with a printed material, signaling of aspiration risk in a care plan board within the room and development of a sialorrhea treatment protocol. HAP surveillance was conducted in accordance to CDC definitions and was reported as number of HAP cases per 1,000 patient days. Results: Our first intervention decreased the incidence of HAP in the first semester of 2017 from 1.03 to 0.29 (graph) but was not sustained. The incidence started to increase in the second semester of 2017 and reached a high incidence of 1.87 HAP per 1,000 patient days in the first semester of 2018. The second bundled intervention succeeded in decreasing HAP incidence to 0.57 in the second semester of 2018 and 0.23 in the first semester of 2019. Conclusions: An educational intervention combined with a bundled intervention focused on strategies to reduce the risk of aspiration succeeded in decreasing the incidence of HAP in a step-down unit. However, the sustainability of improvements remains challenging.Funding: NoneDisclosures: None

Computed Tomography Practice Standards for Severe Pediatric Traumatic Brain Injury in the Emergency Department: a National Survey.

Acute medical management of traumatic brain injury (TBI) can be challenging outside of the resuscitation bay, specifically while obtaining a computed tomography (CT) scan of the brain. We sought out to determine the management practices of Canadian traumatologists for pediatric patients with severe TBI requiring CT in the emergency department (ED). In 2019, surveys were sent to trauma directors in hospitals across Canada to ascertain their clinical practices. Team members present in the CT scan included physicians (89%), registered nurses (100%), and respiratory therapists (38%). The average time to and from the CT scanner was one hour. Over half of respondents (56%) had experienced an adverse event in CT with variable access (11-56%) to necessary resuscitation equipment and medications. Significant hypotension (44%) was the most common adverse event experienced. With the exception of an end tidal CO2 monitoring (56%), heart rate, rhythm, respiratory rate, saturation, and blood pressure were always monitored during a CT scan. Head of bed elevation had an approximately equal distribution of flat (44%) versus elevated (56%). The practice variability of Canadian traumatologists may reflect a lack of evidence to guide patient management. Future research and knowledge translation efforts are needed to optimize patient care during neuroimaging.
