Oral Care in Trauma Patients Admitted to the ICU: Viewpoints of ICU Nurses

Use of nursing care bundles for the prevention of ventilator-associated pneumonia in low-middle income countries: A scoping review

BACKGROUND

Ventilator-associated pneumonia (VAP) is a significant concern in low-middle-income countries (LMICs), where the burden of hospital-acquired infections is high, and resources are low. Evidence-based guidelines exist for preventing VAP; however, these guidelines may not be adequately utilized in intensive care units of LMICs.

AIM

This scoping review examined the literature regarding the use of nursing care bundles for VAP prevention in LMICs, to understand the knowledge, practice and compliance of nurses to these guidelines, as well as the barriers preventing the implementation of these guidelines.

STUDY DESIGN

The review was conducted using Arksey and O'Malley's (2005) five-stage framework and the PRISMA-ScR guidelines guided reporting. Searches were performed across six databases: CINAHL, Medline, Embase, Global Health, Scopus and Cochrane, resulting in 401 studies.

RESULTS

After screening all studies against the eligibility criteria, 21 studies were included in the data extraction stage of the review. Across the studies, the knowledge and compliance of nurses regarding VAP prevention were reported as low to moderate. Several factors, ranging from insufficient knowledge to a lack of adequate guidelines for VAP management, served as contributing factors. Multiple barriers prevented nurses from adhering to VAP guidelines effectively, including a lack of audit/surveillance, absence of infection prevention and control (IPC) teams and inadequate training opportunities.

CONCLUSIONS

This review highlights the need for adequate quality improvement procedures and more efforts to conduct and translate research into practice in intensive care units in LMIC.

RELEVANCE TO CLINICAL PRACTICE

IPC practices are vital to protect vulnerable patients in intensive care units from developing infections and complications that worsen their prognosis. Critical care nurses should be trained and reinforced to practice effective bundle care to prevent VAP.

Assessment of Nursing Staff's Knowledge, Attitude and Practice Regarding Oral Hygiene Care in Intensive Care Unit Patients: A Multicenter Cross-sectional Study

Background

Oral care is one of the fundamental nursing care procedures used to decrease oral colonization, dental plaque, respiratory infections, patient stay, and cost. 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. Therefore, the aim of this study was to assess the knowledge, attitude, and practice of nursing professionals regarding oral healthcare in ICUs among various medical institutes across India.

Materials and methods

A questionnaire-based multicentric cross-sectional survey was conducted among registered nursing professionals employed at ICUs of three government tertiary healthcare centers (THC) of India: THC-I, THC-II, and THC-III located in the eastern and northern parts of India between February 2022 and July 2022.

Results

A total of 150 nurses completed the questionnaire form (response rate: 62.5%) comprised of 49 (32.7%) males and 101 (67.3%) females with a mean age of 35.69 ± 7.7 years. Nursing officers' knowledge surpassed that of staff nurses regarding the duration of toothbrushing (p = 0.033). Among interinstitutional comparisons, THC-I nurses showed the greatest knowledge regarding the duration of toothbrushing and the mechanism of preventing saliva accumulation to reduce microbial growth (p = 0.013 and p = 0.003, respectively). Based on total work experience, participants were segregated into three groups: Group I (<7 years), group II (7.1-13.9 years), and group III (>14 years). Group II surpassed the knowledge of denture removal during sleep, cleaning after every meal, and storing in personalized air-tight containers (p = 0.001 and p = 0.036, respectively). The majority from group II recommended plain saline as the material for oral hygiene maintenance in ICU patients (p = 0.008). Group III predominantly practiced the ideal handwashing technique pre- and post-patient contact which was statistically significant (p = 0.001).

Conclusion

This study observed that a knowledge gap exists among the nurses of the three institutes across India pertaining to the oral hygiene care of ICU patients. Nurse's education and implementation of the proper oral hygiene measures for intubated patients in ICU setup is an essential need.

Oral Care Associated With Less Microaspiration in Ventilated Cardiac Patients

Aspiration is common in mechanically ventilated patients and may predispose patients to aspiration pneumonia, chemical pneumonitis, and chronic lung damage. Pepsin A is a specific marker of gastric fluid aspiration and is often detected in ventilated pediatric patients. We investigated the effect of oral care and throat suctioning in the detection of pepsin A in tracheal aspirates (TAs) up to 4 hours after these procedures.

Methods

Twelve pediatric patients between age 2 weeks to 14 years who underwent intubation for cardiac surgery were enrolled in this study. Six of the 12 patients were consented before their surgery with initial specimen collected at the time of intubation and last one shortly before extubation (intubation duration < 24 hours). The remaining 6 patients were consented after cardiac surgery. All specimens were collected per routine care per respiratory therapy protocol and shortly before extubation (intubation duration > 24 hours). Tracheal fluid aspirates were collected every 4 to 12 hours in the ventilated patients. Enzymatic assay for gastric pepsin A and protein determination were performed. The time of oral care and throat suctioning within 4 hours prior was recorded prospectively.

Results

A total of 342 TA specimens were obtained from the 12 intubated pediatric patients during their course of hospitalization; 287 (83.9%) showed detectable total pepsin (pepsin A and C) enzyme activity (> 6 ng/mL) and 176 (51.5%) samples had detectable pepsin A enzyme levels (>6 ng/mL of pepsin A). Only 29 samples of 76 samples (38.2%) had evidence of microaspiration after receiving oral care, while 147 of 266 (55.3%) samples were pepsin A positive when no oral care was provided. Odds ratio is 0.50 (Cl 0.30-0.84), and the number needed to treat is 5.8 (Confidence interval 3.4-22.3). Testing air filters for pepsin was not beneficial.

Conclusion

Oral care is a highly effective measure to prevent microaspiration of gastric fluid in ventilated pediatric patients. The number needed to treat (5.8) suggests this is a very effective prevention strategy. Our study suggests that pepsin A is a useful and sensitive biomarker that allows identification of gastric aspiration.

Nurses' practices and obstacles to oral care quality in intensive care units in Upper Egypt

BACKGROUND

Oral care is one of the fundamental nursing care procedures used to decrease oral colonization, dental plaque, respiratory infections, and patient stay and cost.

AIMS

This study aimed to identify intensive care unit (ICU) nurses' self-assessment of oral care frequency, skill competency, documentation, oral care tools, and obstacles to oral care quality. In addition, it proposed exploring associations between nurses' attitudes about the importance of oral care and the priority of other interventions.

STUDY DESIGN AND SETTING

A cross-sectional descriptive study was conducted in two ICUs (trauma and general) in the main teaching hospital in Upper Egypt. Of 105 nurses selected using convenience sampling, 91 completed the questionnaire.

RESULTS

About 60.4% of ICU nurses did not attend any oral care training programme, 40.7% reported performing oral care four times per shift in intubated patients, 62.6% reported that their skills needed improvement, 37.4% saw themselves as competent, and 86.8% documented oral care in patients' records. Significant positive correlations were found, indicating that nurses' attitudes towards the importance of oral care showed the same tendency as the priority given to other interventions, such as eye care, bowel care, documentation, hygiene, catheters, feeding, and wound care (correlation coefficient [r] = 0.290, 0.511, 0.333, 0.425, 0.431, 0.345, and 0.337, respectively). Furthermore, a toothbrush (84.6%) was often used, while chlorhexidine was not used (90.1%). The major obstacles to the provision of oral care as perceived by the nurses were the fear of aspiration and life-threatening interventions (95.6%), inadequate nurse-patient ratios (94.5%), irregular competency evaluations (92.3%), unavailability of oral care guidelines (92.3%), and shortage of time (84.6%).

CONCLUSION

The participating nurses were mindful of the importance and priority of oral care. Many of them did not attend oral care training programmes and considered that their skills needed improvement. Moreover, ICU nurses reported many obstacles hindering oral care quality.

RELEVANCE TO CLINICAL PRACTICE

This research identifies the importance of developing in-service oral care training programmes to improve ICU nurses' skill competency. High-quality oral care can be provided by focusing on and overcoming obstacles that hinder nurses' oral care practice.

Hospital Dentistry for Intensive Care Unit Patients: A Comprehensive Review

This study aimed to review the oral hygiene status, oral care guidelines, and outcomes of oral care in intensive care unit (ICU) patients from a dental perspective for effective oral care. A literature search using the keywords "Hospital dentistry" OR "Oral care" OR "Intensive care unit" OR "Hospital inpatient" OR "Hospitalization" OR "Emergency service" AND "Oral health" OR "Oral hygiene" OR "Dental plaque" was conducted in PubMed, Medline, and Google Scholar to identify publications reporting on the oral care of the patients admitted to ICUs. A total of 17,400 articles were initially identified. Of these, 58 were selected and classified into three categories for critical review. Seven of these studies evaluated the oral status of ICU patients, and most of the studies indicated that ICU patients had poor oral hygiene or required active dental treatment. Thirty-three of these studies evaluated oral care methods for ICU patients, and in general, oral care methods using chlorhexidine as adjuncts along with tooth brushing were recommended. However, there were insufficient studies to evaluate oral hygiene through effective assessment tools from a dental perspective. In 36 studies on the outcomes of oral care in ICU patients, interventions by dental professionals showed effective results in preventing hospital-acquired infection. This review highlights the importance of establishing guidelines for the evaluation of oral status in ICU patients and summarizes data that may be useful for future studies. Further studies on maintaining good oral hygiene among ICU patients are needed.

Effects of simulation education on oral care practices - a randomized controlled trial

BACKGROUND

Implementation of evidence-based oral care protocols, nurse education programmes and assessment tools may reduce the risk of developing ventilator-associated pneumonia by increasing critical care nurses' knowledge and skills in adhering to current oral care recommendations.

AIMS

To evaluate the longitudinal effects of single-dose simulation education with structured debriefing and verbal feedback on critical care nurses' knowledge and skills in adhering to current oral care recommendations.

DESIGN

A randomized controlled trial with repeated measurements.

METHOD

The data for the study were collected in a single academic centre in a 22-bed adult, mixed, medical-surgical intensive care unit in Finland from February 2012 to March 2014. The effectiveness of simulation education was evaluated through the validated Ventilator Bundle Questionnaire and Observation Schedule at baseline (n = 30) and 24 months (n = 17) after simulation education. Data were analysed using a linear mixed model and intention-to-treat analyses.

RESULTS

During the study period, the average knowledge score in the intervention group increased significantly (44·0% to 56·0% of the total score) in the final post-intervention measurement (p_t  = 0·51, p_g  = 0·002, p_t*g  = 0·023). However, single-dose simulation education with structured debriefing and verbal feedback had no impact on critical care nurses' skill scores.

CONCLUSION

Single-dose simulation education had only a minimal effect on critical care nurses' knowledge and skills in adhering to current oral care recommendations. Despite increased awareness, there was no significant difference in oral care practices between the study groups after simulation education.

RELEVANCE FOR CLINICAL PRACTICE

The need for regularly repeated educational sessions with theoretical training and practical exercises and direct feedback is evident. Certain aspects of oral care, such as prevention of microaspiration of oropharyngeal secretions and moistening of oral mucosa and lips, require more reinforcement than others.
