Validity and reliability of an oral care practice survey for the orally intubated adult critically ill patient

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.

Protocol for a multi-centered, stepped wedge, cluster randomized controlled trial of the de-adoption of oral chlorhexidine prophylaxis and implementation of an oral care bundle for mechanically ventilated critically ill patients: the CHORAL study

BACKGROUND

Routine application of chlorhexidine oral rinse is recommended to reduce risk of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. Recent reappraisal of the evidence from two meta-analyses suggests chlorhexidine may cause excess mortality in non-cardiac surgery patients and does not reduce VAP. Mechanisms for possible excess mortality are unclear. The CHORAL study will evaluate the impact of de-adopting chlorhexidine and implementing an oral care bundle (excluding chlorhexidine) on mortality, infection-related ventilator-associated complications (IVACs), and oral health status.

METHODS

The CHORAL study is a stepped wedge, cluster randomized controlled trial in six academic intensive care units (ICUs) in Toronto, Canada. Clusters (ICU) will be randomly allocated to six sequential steps over a 14-month period to de-adopt oral chlorhexidine and implement a standardized oral care bundle (oral assessment, tooth brushing, moisturization, and secretion removal). On study commencement, all clusters begin with a control period in which the standard of care is oral chlorhexidine. Clusters then begin crossover from control to intervention every 2 months according to the randomization schedule. Participants include all mechanically ventilated adults eligible to receive the standardized oral care bundle. The primary outcome is ICU mortality; secondary outcomes are IVACs and oral health status. We will determine demographics, antibiotic usage, mortality, and IVAC rates from a validated local ICU clinical registry. With six clusters and 50 ventilated patients on average each month per cluster, we estimate that 4200 patients provide 80% power after accounting for intracluster correlation to detect an absolute reduction in mortality of 5.5%. We will analyze our primary outcome of mortality using a generalized linear mixed model adjusting for time to account for secular trends. We will conduct a process evaluation to determine intervention fidelity and to inform interpretation of the trial results.

DISCUSSION

The CHORAL study will inform understanding of the effectiveness of de-adoption of oral chlorhexidine and implementation of a standardized oral care bundle for decreasing ICU mortality and IVAC rates while improving oral health status. Our process evaluation will inform clinicians and decision makers about intervention delivery to support future de-adoption if justified by trial results.

Influence of Institutional Guidelines on Oral Hygiene Practices in Intensive Care Units

BACKGROUND

Maintaining oral hygiene is a key component of preventing ventilator-associated pneumonia; however, practices are inconsistent.

OBJECTIVES

To explore how characteristics of institutional guidelines for oral hygiene influence nurses' oral hygiene practices and perceptions of that practice.

METHODS

Oral hygiene section of a larger survey study on prevention of ventilator-associated pneumonia. Critical care nurses at 8 hospitals in Northern California that had more than 1000 ventilator days in 2009 were recruited to participate in the survey. Twenty-one questions addressed oral hygiene practices and practice perceptions. Descriptive statistics, analysis of variance, and Spearman correlations were used for analyses.

RESULTS

A total of 576 critical care nurses (45% response rate) responded to the survey. Three types of institutional oral hygiene guidelines existed: nursing policy, order set, and information bulletin. Nursing policy provided the most detail about the oral hygiene care; however, adherence, awareness, and priority level were higher with order sets (P < .05). The content and method of disseminating these guidelines varied, and nursing practices were affected by these differences. Nurses assessed the oral cavity and used oral swabs more often when those practices were included in institutional guidelines.

CONCLUSIONS

The content and dissemination method of institutional guidelines on oral hygiene do influence the oral hygiene practices of critical care nurses. Future studies examining how institutional guidelines could best be incorporated into routine workflow are needed.

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

Background:

Many patients with severe traumatic injuries are admitted to intensive care units (ICU). These patients usually require prolonged mechanical ventilation. These interventions require oral intubation and leave the mouth open which consequently impairs the natural antimicrobial activity in the mouth and airways. These patients are also prone to ventilator-associated pneumonia (VAP). Evidence shows that paying attention to oral hygiene in patients under mechanical ventilation is important in helping to prevent VAP.

Objectives:

The present study was conducted to assess the viewpoints and performance of ICU nurses at Birjand hospitals towards oral care of patients under mechanical ventilation.

Patients and Methods:

A cross-sectional study was conducted at ICUs of Imam-Reza and Vali-Asr hospitals, Birjand, Iran. Sampling was done through a census in which 53 ICU nurses participated. Descriptive statistics, Kolmogorov-Smirnov test, Mann-Whitney U tests and Kendall's correlation coefficient were used to analyze the data.

Results:

A total of 53 nurses participated in this study. Most of the nurses had been trained to provide oral care during their university education. According to the participants' opinions, oral care with an average score of 5.72 ranked second among the 10 nursing care domains. The most frequent oral care provided was oral suctioning, normal saline irrigation, and chlorhexidine rinse with 95%, 90%, and 81.3% frequency, respectively.

Conclusions:

Nurses participating in this study considered oral care to be of prime importance. Most of the participants although trained in this area felt the need for continuing training courses.

Intensive care nurses' opinions and practice for oral care of mechanically ventilated patients

Context:

Oral care is an essential aspect of critical care nursing. However, no study has been published on oral care practice of Iranian and Asian nurses. The majority of published studies were conducted in western and European countries.

Aims:

This study aimed to evaluate the nurses’ opinions and practice about oral care in patients under mechanical ventilation.

Settings and Design:

A cross-sectional study was conducted on 130 intensive care nurses from 6 intensive care units in the university hospitals of Iran.

Materials and Methods:

A questionnaire was used to gather the data and charts of 45 patients were evaluated.

Statistical analysis:

Descriptive statistical analysis are presented.

Results:

Oral care obtained the 7^th rank in prority and a mean score of 5.7 on a scale of 1-10. More than 21% of subjects did not perform oral care in their usual duties. High load of writing tasks and personnel shortages were the major barriers to oral care. Only 20% of the patients’ charts contained a report on oral care.

Conclusions:

Nurses did not consider oral care in intensive care patients as a high priority. This result highlights the need to continue education programs on oral care for improving the knowledge and attitude of intensive care nurses with respect to oral care.

Oral care practices for orally intubated critically ill adults

BACKGROUND

Ventilator-associated pneumonia is a major threat to patients receiving mechanical ventilation in hospitals. Oral care is a nursing intervention that may help prevent ventilator-associated pneumonia.

OBJECTIVES

To describe oral care practices performed by critical care nurses for orally intubated critically ill patients and compare these practices with recommendations for oral care in the 2005 AACN Procedure Manual for Critical Care and the guidelines from the Centers for Disease Control and Prevention.

METHODS

A descriptive, cross-sectional design with a 31-item Web-based survey was used to describe oral care practices reported by 347 randomly selected members of the American Association of Critical-Care Nurses.

RESULTS

Oral care was performed every 2 (50%) or 4 (42%) hours, usually with foam swabs (97%). Oral care was reported as a high priority (47%). Nurses with 7 years or more of critical care experience performed oral care more often (P=.008) than did less experienced nurses. Nurses with a bachelor's degree in nursing used foam swabs (P=.001), suctioned the mouth before the endotracheal tube (P=.02), and suctioned after oral care (P<.001) more often than other nurses. Nurses whose units had an oral care policy (72%) reported that the policy indicated using a toothbrush (63%), using toothpaste (40%), brushing with a foam swab (90%), using chlorhexidine gluconate oral rinse (49%), suctioning the oral cavity (84%), and assessing the oral cavity (73%). Oral care practices and policies differed for all those items.

CONCLUSIONS

Survey results indicate that discrepancies exist between reported practices and policies. Oral care policies appear to be present, but not well used.
