Effects of combination oral care on oral health, dry mouth and salivary pH of intubated patients: A randomized controlled trial

Thirst in adult patients in the intensive care unit: A scoping review

PURPOSE

To review the literature on thirst in intensive care unit (ICU) patients and report potential causes, risk factors, diagnosis and measurement tools, as well as potential co-occurrence with other distressing symptoms, and the management of thirst in the ICU.

DESIGN

A scoping review employing the Joanna Briggs Institute methodology.

METHODS

PubMed, MEDLINE, EMBASE and CINAHL were searched from inception to April 2024. Any type of empirical study reporting thirst or associated xerostomia in adult patients (≥18 years) admitted to an ICU or high dependency unit for more than 24 h were included.

RESULTS

The search yielded 907 unique records, and after evaluating 65 full-text publications, 21 studies were included. Thirst intensity was addressed most often (eleven studies), whereas the experience (or quality) of thirst and the validation of a measurement instrument, were addressed in only one study. Although co-occurrence of symptoms was addressed in four studies, only one pilot study looked into the interaction of thirst with other symptoms. Intervention studies have been focussing primarily on mouth-care interventions.

CONCLUSION

Thirst is a distressing symptom in the ICU, with reported high prevalence and intensity. Knowledge about its causes, interventions that incorporate minimising its risk, occurrence and intensity are limited.

IMPLICATIONS FOR CLINICAL PRACTICE

Health care providers should acknowledge thirst as a prominent symptom for ICU patients. They should possess knowledge on the factors that potentially evoke or aggravate thirst. Regular and timely relief of thirst by oral care with cold swabs and the application of menthol can be regarded as a first choice of intervention.

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.

Quantitative oral health assessments in mechanically ventilated patients: A scoping review

BACKGROUND

Oral health is a key contributor to a person's overall health. Previous studies indicate that oral health deteriorates throughout ventilation and may contribute to the development of ventilator-associated pneumonia (VAP). Oral health at the time of initial ventilation may impact on this deterioration.

AIMS

To determine the quantitative clinical assessment methods used to measure oral health and what is currently known regarding the oral health of patients at the time of initial ventilation.

STUDY DESIGN

A systematic literature search using electronic bibliographic databases MEDLINE/PubMed, Embase, CINAHL, and the Cochrane Library was undertaken for this scoping review. Studies were included if patients were >18 years old and mechanically ventilated for <48 h at the time of the first oral assessment.

RESULTS

In total, 12 studies were included. The review demonstrates a limited understanding of clinical oral health at the time of initial ventilation. Significant variation in both assessment methods and reporting of oral health makes comparison of results difficult resulting in a poor overall understanding of oral health at the time of intubation.

CONCLUSION

Standardized assessment and reporting methods may improve clinical application of findings and help direct future research. We suggest developing a core outcome set to ensure consistent use of assessment tools as well as standardized reporting of results.

RELEVANCE TO CLINICAL PRACTICE

It is essential that a good understanding of oral health at the time of initial ventilation is gained so that patients receive more targeted oral hygiene intervention in ICU, potentially leading to improved patient outcomes.

COVID-19 hospitalized patients and oral changes: a case-control study

OBJECTIVES

To investigate the association between hospitalization for COVID-19 and oral changes, and to evaluate whether oral changes can indicate a higher risk of disease progression to death.

MATERIALS AND METHODS

This case-control study analyzed patients hospitalized (university hospital), including those in intensive care unit and clinical wards. The study group comprised 69 COVID-19 positive patients (PCR-test), while the control group included 43 COVID-19 negative patients. A dentist performed oral evaluations, and salivary samples were collected for calcium, phosphatase, and pH analysis. Sociodemographic data, hospitalization information, and hematological test results were collected from electronic-medical records. The presence of oral changes was assessed using chi-square tests, and the predicted risk of death was analyzed using binary logistic regression.

RESULTS

COVID-19 positive patients had a significantly higher prevalence of oral changes compared to COVID-19 negative patients. The presence of any oral changes in COVID-19 positive patients indicated a 13-fold higher risk of mortality. "Bleeding ulcers," "pressure ulcers," and "angular cheilitis" were significantly associated with hospitalization for COVID-19.

CONCLUSION

There may be an association between hospitalization for COVID-19 and the development of oral changes, including bleeding ulcers, pressure ulcers. and angular cheilitis. These oral changes may serve as potential indicator for disease progression an increased risk of death.

CLINICAL RELEVANCE

COVID-19 hospitalized patients have a higher prevalence of oral changes, which indicate an increased risk of mortality. Oral medicine staff should be included in multidisciplinary teams to detect and treat these oral changes promptly.

World Workshop on Oral Medicine VIII: Development of a Core Outcome Set for Dry Mouth: A Systematic Review of Outcome Domains for Xerostomia

OBJECTIVE

The purpose of this study was to identify all outcome domains used in clinical studies of xerostomia, that is, subjective sensation of dry mouth. This study is part of the extended project "World Workshop on Oral Medicine Outcomes Initiative for the Direction of Research" to develop a core outcome set for dry mouth.

STUDY DESIGN

A systematic review was performed on MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials databases. All clinical and observational studies that assessed xerostomia in human participants from 2001 to 2021 were included. Information on outcome domains was extracted and mapped to the Core Outcome Measures in Effectiveness Trials taxonomy. Corresponding outcome measures were summarized.

RESULTS

From a total of 34,922 records retrieved, 688 articles involving 122,151 persons with xerostomia were included. There were 16 unique outcome domains and 166 outcome measures extracted. None of these domains or measures were consistently used across all the studies. The severity of xerostomia and physical functioning were the 2 most frequently assessed domains.

CONCLUSION

There is considerable heterogeneity in outcome domains and measures reported in clinical studies of xerostomia. This highlights the need for harmonization of dry mouth assessment to enhance comparability across studies and facilitate the synthesis of robust evidence for managing patients with xerostomia.

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.

Efficacy and Safety of Oral Hydration 1 Hour After Extubation of Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial

BACKGROUND

Thirst is one of the most common and uncomfortable symptoms in patients after cardiac surgery. The postextubation time for early oral hydration (EOH) remains unclear, and there is a lack of studies on its safety and effectiveness.

OBJECTIVE

The aim of this study was to investigate the effects of oral hydration 1 hour after extubation on thirst, salivary pH, salivary flow, oral mucosa, halitosis, gastrointestinal adverse reactions, aspiration pneumonia, and satisfaction in patients undergoing cardiac surgery.

METHODS

Eighty-four patients who underwent cardiac surgery were randomly assigned into 2 groups, for either conventional oral hydration (COH) or EOH. The EOH group drank 30 mL of warm water 1 hour post extubation and thereafter 50 mL hourly for 4 hours. The COH group had nil per os for 4 hours after extubation. If no dysphagia was evident after 4 hours, the patients were instructed to slowly drink water. Thirst intensity was evaluated every hour before the intervention. Nausea and vomiting were recorded after drinking water. The salivary pH, unstimulated salivary flow rate, oral odor, and oral mucosal moisture were evaluated at 1 hour post extubation, immediately before the intervention, and at 4 hour post intervention. Aspiration pneumonia data were collected within 72 hours post intervention. Satisfaction was assessed before leaving the intensive care unit.

RESULTS

The scores for thirst (3.38 ± 1.04; F = 306.21, P < .001), oral mucosa (2.03 ± 0.74; P < .001), and halitosis (2.77 ± 0.63; P < .001) in the EOH group were significantly lower than those in the COH group. The EOH group had significantly higher salivary pH (6.44 ± 1.06; P < .001), unstimulated salivary flow rates (0.18 ± 0.08; P < .001), and patient satisfaction (4.28 ± 0.45; P < .001) than the COH group. Nausea and vomiting did not differ significantly between groups (P = .60). Aspiration pneumonia was not observed in either group.

CONCLUSIONS

Oral hydration 1 hour after extubation significantly alleviated thirst and stabilized the oral environment without gastrointestinal adverse reactions or aspiration pneumonia, and with increased patient satisfaction.

Oral lesions and saliva alterations of COVID-19 patients in an intensive care unit: A retrospective study

Aim

To detect the type and frequency of oral lesions and clinical conditions suggestive of saliva alterations in COVID‐19 patients in an intensive care unit (ICU), as well as to describe the patient´s management in each case

Methods

Information about oral conditions and mechanical ventilation was collected from oral medicine records of COVID‐19 patients in an ICU (n = 519)

Results

From the total collected, 472 patients (90.9%) were examined by the oral medicine staff. In 242/472 patients (51.3%), alterations in the oral cavity were noted. The most frequent changes were mechanical trauma (18.1%, derived mainly from intubation), vascular/coagulation disturbances (24.1%, petechiae, bruises, varicoses, and oral bleeding), and saliva alterations (24.4%, dry mouth, and sialorrhea). Infectious lesions were mentioned in the oral medicine records (16.9%), most associated with a viral infection (15.7%), mainly herpesvirus. Improved oral change protocols included oral hygiene, use of specific medications, and laser therapy

Conclusion

COVID‐19 patients in the ICU often showed dryness in the oral and mucosa oral lesions related to vascular/coagulation disturbances, and mechanical trauma derived from orotracheal tube. An oral medicine staff must be aligned with the ICU multidisciplinary team to manage COVID‐19 patients, as well as to establish diagnoses and oral cavity treatments.

Risk factors for oral alterations in intensive care unit patients: A pilot cohort study

BACKGROUND

Several studies evidenced the presence of oral alterations in ICU patient. However, data about identification of their risk factors in ICU patients is scarce, especially due to the lack of longitudinal prospective studies. Here, we evaluate the risk factors for the development of oral alterations in a group of ICU patients through a prospective longitudinal cohort.

METHODS

During May-December 2019, 43 ICU patients in a tertiary hospital in Brazil were evaluated. Medical record reviews and oral examinations of each patient were made by 3 dentists in five distinct moments.

RESULTS

Among all patients, 53.5% (n = 23) were female, with a mean age of 59.8 years (±17.4). The incidence of oral alterations was 51.2% (35.6%-66.8%) and among these (n = 22), hyposalivation (n = 9; 40.9%), and lingual biofilm accumulation (n = 9; 40.9%) were the most common. The mean age of the group with oral alterations (66.9 years) was higher compared to the group without alterations (52.3 years). Furthermore, male patients (p = 0.02), older than 60 years (p = 0.004) and treated with mechanical ventilator (p = 0.03) had a higher risk of oral alterations.

CONCLUSIONS

Systemic parameters, as age and mechanical ventilator, could influence the oral environment of ICU patients.

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.

Technology for maintaining oral care after stroke: considerations for patient-centered practice

PURPOSE

Activities of daily living including oral care may be challenging after stroke. Some stroke survivors are not able to complete oral care independently and need assistance from healthcare professionals and care partners. Poor oral hygiene may impact stroke recovery and rehabilitation possibly incurring issues such as aspiration pneumonia, malnutrition, and social isolation. The objective of this paper is to outline practical ways to apply oral care technology in daily use for stroke survivors.

MATERIALS AND METHODS

We reviewed the literature on i) stroke-related impairments impacting oral care, ii) oral hygiene dental devices, and iii) technology for oral care education.

RESULTS

Oral care activities involve integrated skills in the areas of motivation, energy, planning, body movement and sensation, and mental acuity and health. Post-stroke impairments such as fatigue, hemiparesis, and mental impairments may impact oral care activities. Technology may help survivors and caregivers overcome some barriers. Three types of technologies are available for facilitating post-stroke oral care: i) non-powered tools and adaptations; ii) powered oral care tools, and; iii) electronic aids to guide oral care activities. Particular choices should maximise patient safety and autonomy while ensuring accessibility and comfort during oral care tasks.

CONCLUSION

The available device and technologies may help substantially with the accommodations needed for post-stroke oral care, improving the oral health of stroke survivors. Good oral health confers benefit to overall health and well-being and could enhance recovery and rehabilitation outcomes. Nonetheless, more research is necessary to demonstrate the feasibility and effectiveness of technology in stroke contexts.IMPLICATIONS FOR REHABILITATIONOral care may be challenging after stroke due to patient fatigue, hemiparesis, cognitive impairments, and other impaired body functions.Poor oral hygiene may impact stroke recovery and rehabilitation due to risk of aspiration pneumonia, malnutrition, and social isolation.Powered oral care tools, non-powered tools, and adaptations to non-powered tools are some of the technology available to help overcome post-stroke barriers for oral care.Computer programs and online resources for education and guidance for oral care activities may help improve recommendation uptake and compliance.

What nursing sensitive outcomes have been studied to-date among patients cared for in intensive care units? Findings from a scoping review

BACKGROUND

Although many studies have considered mortality and adverse effects as outcomes sensitive to nursing practice, it seems that other outcomes of nursing care in intensive care units have been explored less commonly.

OBJECTIVES

To describe the state-of-science in research in the field of nursing sensitive outcomes in intensive care units and to synthesize outcomes that have been documented to date as being influenced by nursing care.

DESIGN

A scoping review study based on the framework proposed by Arksey and O'Malley, further refined by the Levac and Joanna Briggs Institute was performed in 2019.

DATA SOURCES

The Medline, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Scopus, and Google Scholar electronic databases were searched. In addition, the reference list of included articles was screened.

REVIEW METHODS

Two researchers independently identified publications on the basis of the following criteria: (a) articles that reported nursing sensitive outcomes on critically-ill adult patients admitted to the intensive care unit, (b) as primary and secondary studies, (c) written in English, and (d) without any time frame limitation.

RESULTS

Of the 4,231 records, 112 fully met the inclusion criteria and were included. Publications were mainly authored in the US and Canada (n = 44, 39.2%), and the majority (n = 62, 55.3%) had an observational design. A total of 233 nursing sensitive outcomes emerged, categorized in 35 outcomes, with, on average, two per study included. The most often measured outcomes were pressure ulcers (20 studies) and ventilator-associated pneumonias (19 studies); the less studied outcomes were quality of life, secretion clearance, patient-ventilator dysynchrony, and post-extubation dysphagia. When categorizing outcomes, the ones concerning safety (n = 77, 33.1%) were represented the most, followed by those concerning the clinical (n = 72, 30.9%), functional (n = 70, 30.0%), and perceptual (n = 14, 6.0%) domains. The interdependent outcomes linked to multi-professional interventions (e.g., ventilator-associated pneumonias) were the most frequently studied nursing sensitive outcomes (n = 20, 57.1%), while independent outcomes resulting from autonomous interventions performed by nurses were less often studied (n = 8, 22.9%).

CONCLUSIONS

From a clinical point of view, a large heterogeneity of outcomes influenced by nursing care emerged. However, identified outcomes have been studied with different approaches and metrics, so that future efforts will need to establish homogeneous conceptual and operative definitions. Moreover, increasing efforts in establishing perceptual outcomes, or those close to the fundamentals of nursing care, are suggested in order to better depict the contribution of critical care nurses in the field.

Oral health knowledge, attitude and practices among nurses in a tertiary care hospital in Bangalore, India: a cross-sectional survey

Background: Maintaining good oral health among hospitalized individuals is essential for health outcomes and quality of life. Nurses, being the primary oral care givers require adequate knowledge, attitude and practice in this area to provide effective oral health care. However, limited studies have been undertaken to evaluate this aspect of nursing care in India. Aim: To determine the knowledge, attitude and practices of nurses regarding oral care for hospitalized patients. Design: Cross-sectional survey. Methods: A total of 244 nurses working in a tertiary care hospital in Bangalore, South India were purposively recruited for this study. Data was collected using a structured questionnaire with both closed and open-ended questions about knowledge, attitude and practice regarding oral care. Results: The mean oral health knowledge score was 6.74 out of maximum score of 22. Most nurses were aware of the importance of oral care among inpatients and the effect poor oral hygiene and systemic diseases have on oral health. Deficiencies in knowledge were prevalent in areas including common medications that affect oral health and regarding care of dentures. Nurses, with higher nursing qualifications and working in departments with longer length of stay had higher attitude scores. Most nurses assessed oral health needs within 24hrs of admission. However, there were inconsistencies in the oral health assessment and care protocols followed and documentation. Conclusion: Nurses' attitude towards oral health was positive yet their knowledge in specific aspects of care was inadequate. Their oral health practices needs improvement.

Effect of Oral Care Program on Prevention of Ventilator-associated Pneumonia in Intensive Care Unit Patients: A Randomized Controlled Trial

Background:

Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infections that increase mortality rate and the length of hospitalization. Oral care can improve patient's oral health, however, the role of oral care in the reduction in incidence rate of VAP is indisputable. The aim of this study was to investigate the effect of oral care on the frequency of VAP of patients in intensive care unit.

Materials and Methods:

This clinical trial was conducted on 80 participants who were randomly assigned to a control group and an intervention group from 2016 to 2017. Data were collected at the first, third, and fifth days of the study using a demographic and clinical characteristics questionnaire and the Clinical Pulmonary Infection Score for detecting pneumonia. Data analysis was performed using descriptive and inferential statistics in SPSS software.

Results:

The results of this study showed that the frequency of pneumonia on the third and fifth days was 15.80% (6) and 23.70% (9) in the control group and 10.50% (4) and 7.90% (3) in the intervention group, respectively. Chi-square test did not show a significant difference (p = 0.059); however, the frequency of pneumonia in the intervention group reduced compared with the control group.

Conclusions:

According to the results of this study, the oral care program could not significantly decrease the incidence of VAP in critically ill patients compared with routine oral care practices. Similar studies with a larger sample size and longer duration should be conducted for better results.

The Effects of Aloe vera-Peppermint (Veramin) Moisturizing Gel on Mouth Dryness and Oral Health among Patients Hospitalized in Intensive Care Units: A Triple-Blind Randomized Placebo-Controlled Trial

Objective:

Mouth dryness is one of the most prevalent problems in Intensive Care Units (ICUs). It facilitates dental plaque formation. The aim of this study was to analyze the effects of Aloe vera-Peppermint (Veramin) moisturizing gel on mouth dryness and oral health among patients hospitalized in ICUs.

Methods:

This triple-blind two-group randomized placebo-controlled clinical trial was undertaken in 2016–2017 on a convenient sample of 80 patients. Patients were randomly allocated to an intervention and a placebo group. Oral care for patients in the intervention and the placebo groups was provided for 5 successive days using Veramin moisturizing gel and a placebo gel, respectively. Data were collected at the 1^st, 3^rd, and 5^th days of the study using a demographic and clinical characteristics questionnaire, the Challacombe scale (for mouth dryness assessment), and the Mucosal-Plaque Index (for oral health assessment). The Chi-square, Fisher Exact, Mann–Whitney U, and Friedman tests were used for data analysis.

Findings:

In the 5^th day, the mean score of mouth dryness in the intervention group was significantly lower than the placebo group (P = 0.0001). On the other hand, in the third and the 5^th days, the oral health mean score in the intervention group was significantly lower than the placebo group (P = 0.0001).

Conclusion:

Veramin moisturizing gel is effective in significantly relieving mouth dryness, preventing dental plaque formation, and improving oral health. Thus, it can be used for improving oral care outcomes in ICUs.

Examination of intensive care unit patients' oral health

BACKGROUND

Oral health problems are common complications that most intensive care unit patients experience. There are many factors that affect oral health negatively and nurses have important responsibilities in this regard.

AIM

The aim of this study was assessment of the intensive care unit patients' oral health and risk factors.

METHODS

This study was planned as a descriptive study and conducted between December 2015 and June 2016, with 202 patients in 20 intensive care units of 6 hospitals in Turkey. Data were collected via Data Collection Form and Bedside Oral Exam guide. Oral health assessment of patients was made using a source of light and a tongue depressor.

RESULTS

We observed a significant difference in score of the Bedside Oral Exam guide by age, consciousness, type of respiration and feeding, the frequency of oral health, the total number of drugs, and technique of oral care (P < 0.05). None of the intensive care units were using the oral assessment guide.

CONCLUSION

The result of this study shows that there are various risk factors that adversely affect the oral health of intensive care unit patients. Nurses should undertake assessments on the basis of oral care protocols for patients at risk and carry out evidence-based individualized oral care applications.
