British Association of Critical Care Nurses: Evidence-based consensus paper for oral care within adult critical care units

Infection prevention knowledge related to central line infections and ventilator-associated pneumonias: A survey of Finnish intensive care units

BACKGROUND

Health care-associated infections pose a significant risk for the patients in intensive care due to the use of medical instrumentation required for care.

METHODS

We conducted a cross-sectional, nationwide survey on awareness of recommended infection prevention practices involving central venous catheters and invasive ventilators in intensive care units.

RESULTS

A total of 810 (50% of those surveyed) nurses and physicians participated in the survey. We found that 8% of the respondents had good knowledge of infection prevention in central venous care, while 24% had good knowledge of ventilator-associated pneumonia prevention practices.

DISCUSSION

The overall level of knowledge measured with this nationwide survey was suboptimal. The level varied between units, and depending on individual questions for particular professions. The displayed knowledge may have partially been based on tradition rather than on up-to-date evidence-based guidelines.

CONCLUSIONS

Educational training in evidence-based infection prevention is needed for practical implementation to be improved.

Oral Microbiome Changes During Hospitalization in Older Adults Not Receiving Mechanical Ventilation

BACKGROUND

Oral bacteria can be pathogenic and may change during hospitalization, potentially increasing risk for complications for older adults, including residents of skilled nursing facilities (SNFs).

OBJECTIVES

To compare the oral microbiome at hospital admission by prehospital residence (SNF vs home) in older adults not receiving mechanical ventilation and to assess changes in their oral microbiome during hospitalization.

METHODS

This prospective, observational study included 46 hospitalized adults (≥65 years old) not receiving mechanical ventilation, enrolled within 72 hours of hospitalization (15 admitted from SNF, 31 from home). Oral health was assessed with the Oral Health Assessment Tool at baseline and days 3, 5, and 7. Genomic DNA was extracted from unstimulated oral saliva specimens for microbiome profiling using 16S ribosomal RNA sequencing. Taxonomic composition, relative abundance, α-diversity (Shannon Index), and β-diversity (Bray-Curtis dissimilarity) of bacterial communities were determined.

RESULTS

Most patients were female (70%) and White (74%) or Hispanic (11%). Mean age was 78.7 years. More patients admitted from SNFs than from home had cognitive impairment (P < .001), delirium (P = .01), frailty (P < .001), and comorbidities (P = .04). Patients from SNFs had more oral bacteria associated with oral disease, lower α-diversity (P < .001), and higher β-diversity (P = .01). In the 28 study completers, α-diversity altered over time (P < .001). A significant interaction was found between groups after adjusting for covariates (P < .001).

CONCLUSIONS

Hospitalized older adults admitted from SNFs experience oral microbial and oral health disparities.

Random forest analysis of ICU nurses' knowledge, attitudes and practices in oral care for ventilator-associated pneumonia prevention

BACKGROUND

Oral care is critical for preventing ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients. ICU nurses play a key role in delivering this care but often encounter challenges stemming from knowledge gaps and inconsistent practices.

AIM

To assess ICU nurses' knowledge, attitudes and practices (KAP) in oral care for VAP prevention and identify demographic factors influencing these variations using random forest analysis.

STUDY DESIGN

A multi-centre cross-sectional study was conducted. Between April and June 2023, 291 ICU nurses from five ICUs across three public tertiary hospitals in Ganzhou City were surveyed using proportionate stratified sampling. Likert-scale questionnaires evaluated KAP, and statistical analyses, including t-tests, analysis of variance and random forest models, were used to determine demographic predictors of KAP scores.

RESULTS

The average KAP scores were as follows: knowledge 27.34 (±4.53), attitudes 31.89 (±4.24), and practices 43.13 (±9.0). Significant predictors of KAP included academic titles, professional positions, gender, ICU tenure and department. Common barriers to effective oral care included lack of formal training, time constraints and limited resources.

CONCLUSIONS

ICU nurses demonstrate positive attitudes towards VAP prevention, but significant gaps in knowledge and practice remain. Targeted education, especially for less-experienced and lower qualified nurses, and standardized protocols are essential to improve adherence to oral care practices and reduce VAP incidence.

RELEVANCE TO CLINICAL PRACTICE

The findings highlight the need for tailored educational interventions to address knowledge gaps, particularly among male, less-experienced and lower qualified nurses. Implementing standardized training protocols can enhance oral care practices, improve patient outcomes and reduce VAP incidence.

The effect of prone positioning on ventilator parameters, blood gas levels, and ventilator-associated pneumonia in intensive care unit patients: a randomized controlled trial

OBJECTIVES

This study was planned to compare the prone position and non-prone position groups and to evaluate arterial blood gas results, mechanical ventilator values and ventilator-associated pneumonia (VAP) status before, during, and after patients were brought back to the non-prone position.

DESIGN

This study is a randomized controlled trial with a parallel-group design and a 1:1 allocation ratio. A block randomisation method was used to ensure balanced allocation between two groups.

SETTING

The research was conducted in the 14-bed and 26-bed general ICUs of two private hospitals on the European side of Istanbul.

PARTICIPANTS

The 94 eligible participants were randomly divided into two groups. 52 participants were assigned to the prone position group, while 42 participants were assigned to the non-prone position group, which served as the control group. In the end, 40 participants were in each group.

INTERVENTION

The intervention involved placing patients in the prone position and monitoring their arterial blood gas results, mechanical ventilator values, and VAP status at multiple stages: before, during, and after returning them to the non-prone position. Each patient was followed for a minimum of 5 days.

RESULTS

The majority of the participants were male (51.2%) and aged 45-64 (48.8%). The comparison of experimental and control groups indicated statistically significant difference in saturation, FiO₂, inspiratory-expiratory tidal volume, and blood gas levels of the patients in the treatment group (p = 0.001; p < 0.01).

CONCLUSIONS

The change in the experimental group was greater than in the control group. In conclusion, the mechanical ventilator parameters and blood gas levels of the patients in the treatment group were better than those of the patients in the control group. It is recommended as an effective practice in patients receiving prone position mechanical ventilation (MV).

Effect of different mouthwashes on ventilator-related outcomes and mortality in intensive care unit patients: A network meta-analysis

BACKGROUND

Ventilator-associated pneumonia is a common and life-threatening complication in intensive care unit (ICU) patients. Maintaining oral hygiene is crucial for reducing ventilator-associated pneumonia incidence. Various mouthwash solutions are used for oral care in ICU settings, but their comparative effectiveness remains unclear. This study aims to systematically evaluate and compare the efficacy and safety of commonly used mouthwashes for oral care in mechanically ventilated ICU patients.

METHODS

We searched PubMed, Web of Science, Embase, and Cochrane Library for randomised controlled trials (RCTs) comparing saline, chlorhexidine, sodium bicarbonate, oxidising agents, herbal extracts, and povidone-iodine for oral care in ventilated ICU patients. Outcomes included ventilator-associated pneumonia incidence, ICU mortality, duration of ventilation, and Escherichia coli fixed value. A network meta-analysis (NMA) was conducted to synthesise direct and indirect evidence. This study is registered with the International Platform of Registered Systematic Review and Meta-analysis Protocols, 2023120028.

RESULTS

FourteenRCTs with 1644 participants were included. Oxidising agents showed a trend towards reducing the incidence of VAP compared to the control group (risk ratio: 0.24, 95% confidence interval: 0.05-1.10). Administration of saline was associated with a notable reduction in ICU mortality (risk ratio: 0.18, 95% confidence interval: 0.04-0.88) versus no mouthwash. No significant differences were observed in the duration of mechanical ventilation between chlorhexidine, povidone-iodine, and the control group.

CONCLUSIONS

Antimicrobial mouthwashes, especially chlorhexidine, pose potential risks in ICU patients; oxidising solutions demonstrate relative safety. Saline solution emerges as a promising alternative, associated with a significant reduction in mortality rates. However, the need for large, high-quality RCTs remains paramount to substantiate these findings and establish evidence-based oral-care protocols in ICU settings.

REGISTRATION

This study is registered with the International Platform of Registered Systematic Review and Meta-analysis Protocols, 2023120028.

Comparative efficacy of various oral hygiene care methods in preventing ventilator-associated pneumonia in critically ill patients: A systematic review and network meta-analysis

Oral hygiene care is important for ventilator-associated pneumonia prevention. However, the optimal oral hygiene care approach remains unclear. A network meta-analysis was conducted to compare the efficacy of various oral hygiene care methods for ventilator-associated pneumonia prevention in critically ill patients, and the methods were ranked. A literature search of three representative databases was conducted. We only analyzed parallel randomized controlled trials conducted to analyze the use antiseptics or toothbrushes in oral hygiene care for adult patients undergoing invasive mechanical ventilation in the intensive care unit. The outcome measure was the incidence of ventilator-associated pneumonia. Bias risk was assessed using the Cochrane Risk of Bias 2 tool, and the confidence in the evidence was evaluated using the CINeMA approach. Statistical analyses were performed using R 4.2.0., GeMTC package, and JAGS 4.3.1. The review protocol was registered in PROSPERO (registration number: CRD42022333270). Thirteen randomized controlled trials were included in the qualitative synthesis and twelve randomized controlled trials (2395 participants) were included in the network meta-analysis. Over 50% of the included studies were conducted in medical-surgical intensive care units. Ten treatments were analyzed and 12 pairwise comparisons were conducted in the 12 included studies. Analysis using surface under the cumulative ranking curves revealed that brushing combined with chlorhexidine 0.12% was most likely the optimal intervention for preventing ventilator-associated pneumonia (88.4%), followed by the use of chlorhexidine 0.12% alone (76.1%), and brushing alone (73.2%). Oral hygiene care methods that included brushing had high rankings. In conclusion, brushing combined with chlorhexidine 0.12% may be an effective intervention for preventing ventilator-associated pneumonia in critically ill patients. Furthermore, brushing may be the optimal oral hygiene care method for preventing ventilator-associated pneumonia in the intensive care unit. Further research is needed to verify these findings as the CINeMA confidence rate was low for each comparison.

Assessing the Impact of Oral Care Micro-courses on ICU Nurses' Compliance Through a Mixed-Effects Model: A Quasi-experimental Study

Background Ventilator-associated pneumonia (VAP) is a common and severe hospital-acquired infection, and oral care is an effective preventive measure. However, the compliance and quality of oral care among intensive care unit (ICU) nurses need improvement. Methods This quasi-experimental study was conducted in two ICUs at the first affiliated hospital of Gannan Medical University, Ganzhou, China, involving 74 ICU nurses. The participants were allocated to either a micro-course education group or a conventional education group. Of these, 32 nurses were from the General ICU, and 42 were from the Cardiac ICU. Both groups received oral care education, with the micro-course group receiving video-based instruction, and the conventional group receiving PowerPoint-based training (Microsoft® Corp., Redmond, WA, USA). Data on oral care compliance and levels of Knowledge, Attitudes, and Practices (KAP) were collected at baseline and during follow-ups over one month. Statistical analysis was conducted using a mixed-effects model to compare outcomes between the groups, highlighting variations in ICU nurses' oral care practices across different ICU settings. Results Both education methods had statistically significant effects. The micro-course education group showed earlier and more pronounced improvements in oral care compliance. Quantitatively, the micro-course group experienced a mean increase in compliance of 0.281 (p = 0.032) at the third follow-up, whereas the conventional group saw a mean increase of 0.261 (p = 0.042) at the fifth follow-up. Additionally, KAP levels in both groups improved significantly (p < 0.001). Conclusion This study demonstrates that micro-course education has a statistically significant impact on ICU nurses' oral care compliance and levels of KAP in the short term. Although there was no significant difference in oral care compliance between the micro-course and conventional education methods, the micro-course showed certain advantages in teaching quality. Long-term studies are needed to evaluate the sustainability of these improvements. Promoting micro-course education in ICU nursing practice may enhance oral care practices and potentially reduce the incidence of VAP.

An Interactive Virtual Reality Simulation Developed to Teach Oral Care Application Skills on Unconscious Patients: Effect on the Knowledge Level of Nursing Students

A quasi-experimental one-group pretest-posttest research design was used in this study. For the purpose of the research, a computer-based and interactive virtual reality simulation for applying oral care on an unconscious patient was developed to be integrated into the existing nursing curriculum. It was concluded that the computer-based, interactive virtual reality simulation design developed for teaching oral care application on an unconscious patient had a high impact on education and the sense of presence. It was further determined that the virtual reality simulation, developed herein, improved the students' knowledge level on the subject (P < .05). It was concluded that the computer-based, interactive virtual reality simulation prepared for applying oral care on an unconscious patient is an effective and usable method in nursing education.

Care Bundle Approach for Oral Health Maintenance and Reduction of Ventilator-Associated Pneumonia

Caring for patients in the intensive care unit (ICU) creates competing priorities of interventions for nurses and other health care providers. Oral care might be prioritized lower; however, its neglect may lead to sequelae such as extended time in the ICU, nosocomial diseases most notably ventilator-associated pneumonia (VAP), or oral problems. Safe patient care depends on effective and efficient oral care. The aim of this study was to lower the incidence of VAP and maintain oral health through implementing an "oral care bundle" for mechanically ventilated (MV) patients. Using a quasi-experimental design, we divided 82 adult MV patients in the ICUs of a university-based hospital in Egypt into a control group (n = 41) that received the standard of care and a bundle group (n = 41) that received an "oral care bundle." The results of the study reported a significantly lower incidence of VAP in the intervention group (P = .015). It can be concluded that there is a significant relationship between receiving an oral care bundle and improved oral health and a reduction in the VAP rate among MV patients. This highlights the need to incorporate the oral care bundle in the daily nursing care for MV patients.

Nurse-led intervention to improve oral mucosal health of intubated patients in the intensive care unit: A prospective study

BACKGROUND

This prospective study aimed to explore the effectiveness of an oral care intervention with Tegaderm on the oral mucosal health of intubated patients.

METHODS

A total of 70 intubated patients were included and randomly assigned to 1 of 3 groups, clean water brushing teeth (n = 23), brushing teeth combined with mouthwash (BTM) (n = 23), and brushing teeth combined with mouthwash and Tegaderm (BTMT) (n = 24). The Oral Mucositis Assessment Scale (OMAS) was applied to evaluate the patient's oral mucosal health before and after oral care intervention.

RESULTS

The BTMT group had lower OMAS scores in almost all regions of the oral cavity, compared to the brushing teeth and BTM groups. The general linear model for repeated measurement indicated the BTMT group had the lowest total OMAS scores from Day 2 to Day 4 after the initiation of baseline OMAS evaluation. Of the 3 intervention groups, the BTMT group had the shortest length of endotracheal intubation. The BTMT group had the lowest incidence rate of ventilator-associated pneumonia; however, no significant between-group differences were found.

CONCLUSIONS

BTMT effectively reduced the decline in oral mucosal health that was caused by endotracheal intubation and shortened the length of endotracheal intubation.

Ventilator-Associated Pneumonia Prediction Models Based on AI: Scoping Review

Background

Ventilator-associated pneumonia (VAP) is a serious complication of mechanical ventilation therapy that affects patients' treatments and prognoses. Owing to its excellent data mining capabilities, artificial intelligence (AI) has been increasingly used to predict VAP.

Objective

This paper reviews VAP prediction models that are based on AI, providing a reference for the early identification of high-risk groups in future clinical practice.

Methods

A scoping review was conducted in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. The Wanfang database, the Chinese Biomedical Literature Database, Cochrane Library, Web of Science, PubMed, MEDLINE, and Embase were searched to identify relevant articles. Study selection and data extraction were independently conducted by 2 reviewers. The data extracted from the included studies were synthesized narratively.

Results

Of the 137 publications retrieved, 11 were included in this scoping review. The included studies reported the use of AI for predicting VAP. All 11 studies predicted VAP occurrence, and studies on VAP prognosis were excluded. Further, these studies used text data, and none of them involved imaging data. Public databases were the primary sources of data for model building (studies: 6/11, 55%), and 5 studies had sample sizes of <1000. Machine learning was the primary algorithm for studying the VAP prediction models. However, deep learning and large language models were not used to construct VAP prediction models. The random forest model was the most commonly used model (studies: 5/11, 45%). All studies only performed internal validations, and none of them addressed how to implement and apply the final model in real-life clinical settings.

Conclusions

This review presents an overview of studies that used AI to predict and diagnose VAP. AI models have better predictive performance than traditional methods and are expected to provide indispensable tools for VAP risk prediction in the future. However, the current research is in the model construction and validation stage, and the implementation of and guidance for clinical VAP prediction require further research.

Probable Non-Ventilator-Associated Hospital-Acquired Pneumonia: A Case Report

INTRODUCTION

Non-ventilator-associated hospital-acquired pneumonia is a preventable health care-associated infection accounting for 1 in 14 hospital deaths. Clinical factors influencing this condition include oral health and bacteria and oral care. This case report addresses diagnostics and clinical variables related to non-ventilator-associated hospital-acquired pneumonia and emphasizes the importance of prevention.

CLINICAL FINDINGS

A 90-year-old woman was admitted to the hospital with shortness of breath and generalized weakness from new-onset atrial fibrillation and suspected heart failure exacerbation. During the hospitalization, her oral health status declined and oral bacterial colonization shifted, with Neisseria becoming the most common oral bacterial genus around the time of development of probable non-ventilator-associated hospital-acquired pneumonia.

DIAGNOSIS

The patient had new respiratory symptoms and a chest radiograph positive for pneumonia on day 4 and was subsequently diagnosed with probable non-ventilator-associated hospital-acquired pneumonia.

INTERVENTIONS

Intravenous antibiotic treatment was initiated. Oral care was completed on only 2 of 7 days. The patient received limited ambulation assistance and encouragement from staff and family members. No dysphagia screening was documented.

OUTCOMES

On day 6, the patient was discharged with oral antibiotics to her independent living facility with home health care.

CONCLUSIONS

Consistent oral care, early and frequent physical activity, and measures aimed to reduce aspiration risk are key interventions for all hospitalized patients to prevent non-ventilator-associated hospital-acquired pneumonia. Further research is warranted to assess shifts in oral bacteria and general oral health during hospitalization, which could provide clinically meaningful data on risk for non-ventilator-associated hospital-acquired pneumonia.

Evaluation of clinical oral care outcomes according to nursing outcomes classification

PURPOSE

This research was planned to follow the healing process of the oral mucosa in patients in intensive care with an "Impaired Oral Mucous Membrane Integrity" nursing diagnosis based on the "NOC (1100) Oral Health Assessment" outcome criteria.

METHOD

This study, which was planned in a methodological and descriptive type of research, was carried out with 50 patients who were hospitalized in the intensive care clinic of a state hospital between June and December 2022, with a nursing diagnosis of "Impaired Oral Mucous Membrane Integrity." Data were collected using a Patient Information Form and the "NOC (1100) Oral Health Evaluation Scale" for the nursing outcomes classification. In the analysis of the data descriptive statistical methods, Pearson correlation test, Friedman test as well as Cohen's kappa test were used to evaluate the agreement between two independent observers.

FINDINGS

In the study, content validity index value of the NOC scale was calculated to be 0.90. The examination of the participants' mean scores on the NOC (1100) Oral Health Assessment Scale showed that there were statistically significant differences in terms of the repeated evaluations, except for the NOC indicators of "Oral mucosal integrity," "Gum integrity," and "Tooth integrity" (p < 0.01). No statistically significant correlation was found between the mean NOC scale scores of the patients according to the variables of age, body mass index, mechanical ventilation time, and length of stay in the intensive care unit (p > 0.05).

CONCLUSIONS

The findings showed that the Turkish version of NOC (1100) Oral Health Assessment Scale was a valid tool for monitoring the healing process of the oral mucosa in patients in intensive care.

IMPLICATIONS OF NURSING PRACTICE

With the use of NOC (1100) Oral Health Assessment Scale, a common language will be formed in the evaluation for monitoring the healing process of the oral mucosa in nursing care.

Nation-wide survey of oral care practice in Japanese intensive care units: A descriptive study

Oral care for critically ill patients helps provide comfort and prevent ventilator-associated pneumonia. However, a standardized protocol for oral care in intensive care units is currently unavailable. Thus, this study aimed to determine the overall oral care practices, including those for intubated patients, in Japanese intensive care units. We also discuss the differences in oral care methods between Japanese ICUs and ICUs in other countries. This study included all Japanese intensive care units meeting the authorities' standard set criteria, with a minimum of 0.5 nurses per patient at all times and admission of adult patients requiring mechanical ventilation. An online survey was used to collect data. Survey responses were obtained from one representative nurse per intensive care unit. Frequency analysis was performed, and the percentage of each response was calculated. A total of 609 hospitals and 717 intensive care units nationwide participated; among these, responses were collected from 247 intensive care units (34.4%). Of these, 215 (87.0%) and 32 (13.0%) reported standardized and non-standardized oral care, respectively. Subsequently, the data from 215 intensive care units that provided standardized oral care were analyzed in detail. The most common frequency of practicing oral care was three times a day (68.8%). Moreover, many intensive care units provided care at unequal intervals (79.5%), mainly in the morning, daytime, and evening. Regarding oral care methods, 96 (44.7%) respondents used only a toothbrush, while 116 (54.0%) used both a toothbrush and a non-brushing method. The findings of our study reveal current oral care practices in ICUs in Japan. In particular, most ICUs provide oral care three times a day at unequal intervals, and almost all use toothbrushes as a common tool for oral care. The results suggest that some oral care practices in Japanese ICUs differ from those in ICUs in other countries.

Assessment of the Oral Health Status of Patients Admitted to Pediatric Intensive Care Units: A Cross-Sectional Study

BACKGROUND

It is important to detect oral health problems early among patients admitted to pediatric intensive care units to establish the diagnosis and consequently allow nurses to plan appropriate oral care practices.

OBJECTIVES

The study aimed to assess the oral health status of patients admitted to pediatric intensive care units.

METHODS

This descriptive cross-sectional study was conducted from June to September 2021 in the pediatric intensive care units of 3 hospitals. A total of 88 children were included in the study. An intraoral assessment was performed using a tongue depressor and a flashlight, and data were collected using a patient information form and the Oral Assessment Guide (OAG).

RESULTS

The mean OAG score was 8.45 ± 2.876 points. A significant difference was found in the OAG score between the patients 60 months or younger and those 61 months or older (P < .05). The OAG score was significantly associated with the use of diuretics (P < .05) and the frequency of oral care (P < .05). A negative relationship was found between the OAG score and the Glasgow Coma Scale score (P < .05).

CONCLUSIONS

The oral health status of the patients worsened as their age increased, and their state of consciousness decreased. Oral care was more frequently applied to the patients who received artificial respiration. The study provides evidence-based data regarding the early detection of the factors threatening oral health and the necessary precautions.

Perceptions, barriers, and challenges of oral care among nursing assistants in the intensive care unit: a qualitative study

BACKGROUND

Although oral hygiene is closely related to various diseases, it is sub-optimal in the Intensive Care Unit (ICU). Oral care in the ICU is challenged by nursing workloads, low staffing, and higher acuity patients, there are few policies and written guidelines for oral care. Nurses often delegate oral care to nursing assistants (NAs) whose role is overlooked. This study is to explore the perspectives, obstacles, and challenges of NAs in the oral care of the ICU.

METHODS

A qualitative study and semi-structured interviews were conducted with NAs in three ICU units, and Colaizzi's phenomenological method was used to analyze the records.

RESULTS

Initially, 13 NAs met the inclusion criteria, and two did not participate in this study as they refused to be recorded. Finally, 11 ICU NAs were interviewed, with three receiving face-to-face interviews and eight receiving telephone interviews. Using Colaizzi's phenomenological method, two themes and eight subthemes emerged from the data, we examined the self-perception, barriers and challenges of NAs regarding oral care and identified the subthemes: (1) The target audience, frequency, and importance; (2) Role; (3) Evaluation; (4) Patient-related factors; (5) Oral care tools; (6) Psychology of NAs; (7) Lack of education and training; (8) Lack of team support.

CONCLUSION

Nursing assistants whose roles are overlooked by the nursing team are important members of the ICU team. Though oral care is closely related to disease prevention, it is rarely considered an essential task. Major barriers to implementing oral care in the ICU environment and patients include the psychological quality of participants, non-standard education and training, and inadequate team support. The expectation is that medical personnel will prioritize oral hygiene and recognize the significance of NAs in nursing work. Furthermore, future ICU oral care should investigate suitable tools and mouthwashes, simplified and standardized processes, standardized training, and multidisciplinary team collaboration.

Oral health care in adult intensive care units: A national point prevalence study

BACKGROUND

The importance of good oral hygiene for patients in Intensive Care Units (ICUs) is well recognized, however, the most effective way to achieve good oral care in the ICU is unclear.

AIM

This study aimed to provide a national picture of oral care practices in adult ICUs in the United Kingdom (UK) to identify areas for improvement.

STUDY DESIGN

A national one-day point prevalence study was undertaken in adult ICUs in the UK in the period from 30th September to 14th October 2021. Data were collected on all patients in the ICU on the date of data collection. Using a validated electronic data collection form, anonymised data were collected on methods and frequency of oral care provided, and the use of oral care protocols within the ICU. Data were analysed using descriptive analysis.

RESULTS

Data from 195 patients in 15 ICUs in England, Wales and Northern Ireland were collected. Written oral care protocols were available for use in the care of 65% (n = 127) of patients. 73% (n = 142) of patients received oral care within the 24-h period. Oral care methods included toothbrushing 41% (n = 79), foam sticks 3% (n = 5), moisturizing the oral cavity 10% (n = 19) and mouth rinse with chlorhexidine 3% (n = 5) and other oral care methods not specified 12% (n = 23). 44% (n = 85) of patients had an oral assessment within the 24-h period and variable assessment methods were used.

CONCLUSION

There is large variability in oral care provision and methods for intubated ICU patients and a lack of consensus was revealed in the study. Oral assessment is conducted less frequently using multiple tools. Optimal oral care standards and further research into oral care provision is pivotal to address this important patient-relevant practice.

RELEVANCE TO CLINICAL PRACTICE

Oral care is a fundamental part of care for ICU patients, however, there is a large degree of variability, and oral care is often not based upon oral assessment. The use of an oral care protocol and oral assessments would help to improve patient care, ease of use for staff and provide a tailored oral care plan for patients, improving efficiency and preventing wasted resources.

Effect of clove mouthwash on the incidence of ventilator-associated pneumonia in intensive care unit patients: a comparative randomized triple-blind clinical trial

OBJECTIVES

Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infections in intensive care units (ICUs), and the use of mouthwash is the most widely used method to prevent its incidence. The aim of this study was to investigate effect of clove mouthwash on the incidence of VAP in the ICU.

MATERIALS AND METHODS

This comparative, randomized, triple-blind, clinical trial was conducted on 168 eligible ICU patients at Kosar Hospital in Semnan, Iran, during 2021-2022, who were divided into intervention and control groups using random blocks. The intervention group received clove extract mouthwash at 6.66% concentration, and the control group received chlorhexidine 0.2% twice a day for 5 days (routine care). Data were collected using a demographic questionnaire, and disease severity was measured based on the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, oral health status was examined using the Beck Oral Assessment Scale (BOAS), and VAP diagnosis was made based on the Modified Clinical Pulmonary Infection Score (MCPIS).

RESULTS

Before the intervention, there was no significant difference in disease severity (p = 0.412) and oral health status (p = 0.239) between the patients in the two groups. After the intervention, 20.2% of the patients in the intervention group and 41.7% of those in the control group acquired VAP. The risk of VAP was 2.06 times higher in the control group than in the intervention group (p = 0.005, 95% CI: 1.26-3.37, RR = 2.06), but the severity of VAP did not differ significantly between the patients in the two groups (p = 0.557).

CONCLUSION

The findings showed that clove mouthwash reduces the incidence of VAP significantly.

CLINICAL RELEVANCE

Clove mouthwash can be used as a simple and low-cost method to prevent VAP in ICU patients.

Oral care in intensive care units: Lithuanian nurses' attitudes and practices

AIM

This study examines the attitudes and practices of ICU nurses towards the provision of oral care to their patients.

OBJECTIVE

We conducted this cross-sectional survey about oral health care practices in ICUs in Lithuania.

METHODS

We used a self-administered 20-item questionnaire to survey the current oral care practices, training, and attitudes of 108 nurses. The questionnaire was based on previous studies to gather information related to the attitudes, oral care practices, and training of ICU nurses. We used the chi-square test to analyze relationships between the categorical variables.

RESULTS

Most (88, 82%) of the nurses stated that oral care is important. Although most (83, 77%) had adequate training, a clear majority (98, 91%) of the nurses reported a willingness to learn more. Most (78, 72%) of the nurses found the oral cavity difficult to clean, and (71, 66%) found doing so unpleasant. When performing oral care, the nurses used mostly foam swabs (62, 61%) and moisturizers (54, 53%). More than half (57, 57%) of the nurses expressed a need for more hospital support.

CONCLUSIONS

Nurses working in ICUs reported that oral care is a high priority for their patients, but a difficult and unpleasant task. Nurses provided oral care mainly with toothbrushes, foam swabs, and moisturizers.

Nurses' practice and educational needs in oral care for postoperative patients with oral cancer in ICUs: a multicenter cross-sectional study

Background

Surgical incision, endotracheal intubation, structural changes in the oral cavity, and other factors lead to a divergence in oral care between patients after oral surgery and ordinary inpatients. High-quality oral care can reduce the incidence of incision infection and ventilator-associated pneumonia. However, there is a lack of guidelines or expert consensus on oral care after oral cancer surgery. Therefore, the aim of this study was to assess the practicing situation of nurses in the intensive care unit (ICU) for postoperative patients with oral cancer and their need for training.

Methods

A multicenter cross-sectional study design was conducted in 19 ICUs of 11 tertiary hospitals from Henan province in China. Data were collected from 173 nurses and 19 head nurses online using a structured questionnaire. Mann–Whitney U and Kruskal–Wallis H tests were performed to analyze the data using SPSS (Version 25.0).

Results

Seven ICUs (36.8%) developed evaluation regulations for the oral care of postoperative patients with oral cancer, and eight ICUs (42.1%) described the operating standards. A total of 173 nurses completed the questionnaire, and the median score was 75 (68, 78). Almost all of the examined nurses (91.2%) assessed patients’ oral hygiene at a fixed time, while in 52.0% and 28.3% of nurses, the first oral care and frequency of oral care after surgery was determined based on the individual patient’s situation. More than half of the nurses (55.5%) spent approximately 5–10 min conducting oral care for patients. Physiological saline solution (82.7%), swabbing (91.9%), and oral care package with cotton ball (86.1%) were the most popular oral care mouthwash, method, and tool, respectively. Nurses sought help from senior nurses (87.3%) and doctors (83.8%), mostly to solve difficulties of oral care. Moreover, 76.9% of the nurses believed that the lack of knowledge and skills surrounding oral care was the main barrier for nurses to implement oral care. The majority of participants (69.4%) had never received continuing education or training in oral care for postoperative patients with oral cancer, and almost all (98.8%) of the respondents stated their preference to receive training in standardized oral care skills. Indications and contraindications (84.4%), tools (81.5%), and mouthwash (80.9%) of oral care were the items that the respondents were most eager to learn about. Approximately three quarters of nurses preferred scenario simulation practice as the training method.

Conclusion

Although the participants had high oral care scores for postoperative patients with oral cancer, there was great diversity in the practice. The lack of oral care knowledge was deemed the main barrier in delivering quality oral care, and the educational need was stated by almost all participants. We suggest that a standard protocol or clinical practice guidelines for oral care for postoperative patients with oral cancer should be developed, and nurses should be educated to equip them with professional knowledge and skills.

Management of Ventilator-Associated Pneumonia: Quality Assessment of Clinical Practice Guidelines and Variations in Recommendations on Drug Therapy for Prevention and Treatment

Purpose: To assess the quality of clinical practice guidelines (CPGs) related to drug therapy for prevention and control of ventilator-associated pneumonia (VAP) and compare the differences and similarities between recommendations.

Methods: Electronic databases (including PubMed, Cochrane library, Embase, Web of Science), guideline development organizations, and professional societies were searched to identify CPGs for VAP from 20 January 2012 to 20 January 2022. The Appraisal of Guidelines Research & Evaluation (AGREE) II instrument was used to evaluate the quality of the guidelines. The recommendations on drug therapy for prevention and treatment for each guideline were extracted, and then a descriptive synthesis was performed to analyze the scope/topic, and consistency of the recommendations.

Results: Thirteen CPGs were included. The median score and interquartile range (IQR) in each domain are shown below: scope and purpose 72.22% (63.89%,83.33%); stakeholder involvement 44.44% (38.89%,52.78%); rigor of development 43.75% (31.25%,57.29%); clarity and presentation 94.44% (77.78%,94.44%); applicability 20.83 (8.34%,33.34%) and editorial independence 50% (33.33%,66.67%). We extracted 21 recommendations on drug therapy for prevention of VAP and 51 recommendations on drugs used for treatment. Some controversies remained among the included guidelines.

Conclusion: There is considerable variability in the development processes and reporting of VAP guidelines. Despite many similarities, the recommendations still had some inconsistencies in the details. For the prevention and treatment of VAP, local microbial epidemiology and antibiotic sensitivity must be considered, and recommendations should be regularly revised as new evidence emerges.

Tutorial on Clinical Practice for Use of the Fiberoptic Endoscopic Evaluation of Swallowing Procedure With Adult Populations: Part 1

PURPOSE

Representatives of the American Board of Swallowing and Swallowing Disorders (AB-SSD) and American Speech-Language-Hearing Association (ASHA) Special Interest Group (SIG) 13: Swallowing and Swallowing Disorders (Dysphagia) developed this tutorial to identify and recommend best practice guidelines for speech-language pathologists who conduct and interpret fiberoptic endoscopic evaluation of swallowing (FEES) procedures in adults. This document also includes proposed training needs and methods for achieving competency. Expert opinion is provided regarding indications for performing the FEES exam, potential contraindications, adverse effects and safety, equipment and personal protection, the exam protocol, interpretation and documentation of findings, and training requirements to perform and interpret the exam.

CONCLUSIONS

This tutorial by the AB-SSD and SIG 13 represents the first update about the FEES procedure since ASHA's position paper and technical report published in 2004. Creation of this document by members of the AB-SSD and SIG 13 is intended to guide professionals who are training for or practicing FEES in the adult population toward established best practices and the highest standards of care.

Cost-effectiveness analysis of nasojejunal tube feeding for the prevention of pneumonia in critically ill adults

BACKGROUND

Nasojejunal tube (NJT) feeding has demonstrated value in reducing pneumonia in critically ill adults who require enteral nutritional (EN) support. This study discusses whether EN support via nasojejunal tube (NJT) feeding is more cost-effective than nasogastric tube (NGT) feeding in reducing pneumonia.

METHODS

A decision tree model was created. The analysis was based on data from a health care provider in China. Model inputs were derived from published data. The endpoints included incremental cost per pneumonia infection avoided, incremental cost-effectiveness ratio (ICER), net monetary benefit (NMB) and incremental net monetary benefit (INMB) associated with prevention of pneumonia. The uncertainty was assessed through one-way and probabilistic sensitivity analysis.

RESULTS

The base case analysis showed that EN support via NJT feeding resulted in 0.7453 quality-adjusted life years (QALYs) at a cost of $3018.83 compared to NGT feeding, which resulted in 0.7354 QALYs at a cost of $4788.76. NJT feeding was better than NGT feeding, providing an INMB of $2,075.09 and an ICER of $-178,813.96 per QALY gained, and the cost per pneumonia infection prevented was $16,808.51. The probabilistic sensitivity analysis indicated that NJT feeding was more cost-effective in 83.4% of the cases, with a cost below the WTP threshold. The NMB and INMB estimation for different WTP thresholds also indicated that NJT feeding is the optimal strategy.

CONCLUSIONS

EN support via NJT feeding was a more cost-effective strategy than NGT feeding in preventing pneumonia in critically ill adults. This article is protected by copyright. All rights reserved.

Oral health care for the critically ill: a narrative review

Background

The link between oral bacteria and respiratory infections is well documented. Dental plaque has the potential to be colonized by respiratory pathogens and this, together with microaspiration of oral bacteria, can lead to pneumonia particularly in the elderly and critically ill. The provision of adequate oral care is therefore essential for the maintenance of good oral health and the prevention of respiratory complications.

Main body

Numerous oral care practices are utilised for intubated patients, with a clear lack of consensus on the best approach for oral care. This narrative review aims to explore the oral-lung connection and discuss in detail current oral care practices to identify shortcomings and offer suggestions for future research. The importance of adequate oral care has been recognised in guideline interventions for the prevention of pneumonia, but practices differ and controversy exists particularly regarding the use of chlorhexidine. The oral health assessment is also an important but often overlooked element of oral care that needs to be considered. Oral care plans should ideally be implemented on the basis of an individual oral health assessment. An oral health assessment prior to provision of oral care should identify patient needs and facilitate targeted oral care interventions.

Conclusion

Oral health is an important consideration in the management of the critically ill. Studies have suggested benefit in the reduction of respiratory complication such as Ventilator Associated Pneumonia associated with effective oral health care practices. However, at present there is no consensus as to the best way of providing optimal oral health care in the critically ill. Further research is needed to standardise oral health assessment and care practices to enable development of evidenced based personalised oral care for the critically ill.

Smart secretion management to protect nurses from COVID19 and other infectious diseases

Background

COVID‐19 has been linked to over 40 million infections and 1.1 million deaths in 210 countries as of October 19, 2020. This highly contagious communicable disease has put not only infected individuals but other patients and frontline workers like nurses at risk in hospitals, especially in Intensive Care units (ICUs).

There is a need for minimizing patient contact, improving hand hygiene practices, and optimizing healthcare provider time, especially nurses. Globally it is estimated that nearly a million health care providers have been infected with COVID‐19 as of the end of October 2020.

Methods

This retrospective service evaluation documents the experience of health care providers in a COVID‐19 ICU in India that was used to implement new protocols for secretion management and oral hygiene. Patient chart information and staff feedback were utilized.

Intervention

This pilot study captures the practical benefits of using VAPCare, an automated, closed‐loop system for oral secretion removal.

Results

Six patients were included in this small‐scale study; three patients following the current standard of care for suctioning and oral hygiene and three receiving the new VAPCare and Lumen device protocol. With the new device protocol, the number of infected secretion interactions by a nurse was 50% lower, and nursing time spent on oral hygiene and secretion management 70% less than seen with the current standard of care. The number of disposable gloves used with VAPCare and Lumen was reduced by over 50%. All 10 nurses and six doctors gave positive feedback on device usage. The department recommended updating protocols to prioritize the use of the new secretion management system for patients with COVID19 and other highly contagious conditions.

Conclusion

The findings are an early indication that using VAPCare for patients could help protect infected patients, other ICU patients, and health care workers.
