Designing Technology to Decrease Pneumonia in Intubated Trauma Patients

Interventions to promote oral care regimen adherence in the critical care setting: A systematic review

BACKGROUND

Oral care is a fundamental nurse-led intervention in the critical care setting that provides patient comfort and prevents adverse outcomes in critically ill patients. To date, there has been minimal focus on nurse-focused interventions to improve adherence to oral care regimens in the adult intensive care unit setting.

OBJECTIVES

The objectives of this study were to (i) identify types and characteristics of interventions to improve oral care adherence amongst critical care nurses and intervention core components, (ii) evaluate the effectiveness of interventions to improve adherence of oral care regimens, and (iii) identify the types of outcome measures used to assess oral care regimen adherence.

DESIGN

This is a systematic review in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

DATA SOURCES

Key bibliographic databases and platforms, including Scopus, Cochrane, MEDLINE, CINAHL, Embase, PsycINFO, ProQuest, and Web of Science, were searched for studies published before July 2020. The Joanna Briggs Institute's quality appraisal tool was used to assess risk of bias in included studies.

RESULTS

A total of 21 original research studies were identified, of which 18 studies used multifaceted interventions. In accordance with the Joanna Briggs Institute's quality appraisal tools, four of the 20 quasi-experimental studies were rated as high quality. The one randomised control trial was of moderate quality. Outcome measures included oral care adherence behaviours, oral care knowledge, self-reported adherence, and documentation. Improved effectiveness in oral care adherence was reported in 20 studies.

CONCLUSIONS

Review findings confirm interventions to change behaviours improve oral care adherence. The most effective interventional approach could not be determined owing to heterogeneity in intervention design and outcome measures. Oral care in the intensive care unit is a vital, nurse-led activity that reduces the risk of hospital-acquired infection. It is recommended that future research adopt implementation science methods to ensure stakeholder engagement and feasibility.

Ventilator-Associated Pneumonia: How Do the Different Criteria for Diagnosis Match Up?

Ventilator-associated pneumonia (VAP) affects up to 30 per cent of ICU patients and has been associated with increased morbidity and mortality. We identified factors associated with prolonged latency of VAP and evaluated its effects on survival and additional outcomes. We also determined the sensitivity of various clinical definitions of VAP, including the Centers for Disease Control and Prevention (CDC) 2013 criteria. We hypothesized that the CDC 2013 criteria would have poor sensitivity. We collected data on 102 subjects who developed VAP between 2012 and 2017. We conducted a Kaplan-Meier survival analysis with Cox proportional hazards regression and generalized linear models/ANOVA to look at predictor variables along with multivariate models for each outcome. White patients, nonsurgical patients, patients with renal failure, altered mental status, increased FiO2, and increased positive end-expiratory pressure had worse survival. Trauma patients, patients with positive sputum cultures, and patients with suspected pneumonia had better survival. Sensitivity of the CDC 2013 criteria was only 44.1 per cent. Our results emphasize the importance of having a high index of suspicion for VAP in ventilator-dependent patients. The 2013 CDC criteria failed to detect 55.9 per cent of confirmed VAP cases. These results are concerning because undetected VAP can have devastating consequences for patients.

Nurses' perception and attitudes towards oral care practices for mechanically ventilated patients

OBJECTIVES

To explore the perception and attitudes of intensive care unit (ICU) nurses towards oral care practice for mechanically ventilated (MV) patients.

METHOD

A descriptive cross-sectional design was used in this study. A convenience sample of 96 ICU nurses completed a questionnaire on their perception and  attitudes towards oral care. The study setting was 3 representative Jordanian hospitals in Al-Karak and the capital, Amman, over a 6-month period between February and September 2016.

RESULTS

Ninety-six nurses participated in the study. The response rate was 76.8%. The results revealed that 65% only follow a specific oral care protocol. Nurses did not adhere to minimal standards. Although nurses' attitude towards oral care was strongly positive, 68% of them perceived it as an unpleasant task and 29% agreed that they had insufficient training; 78% agreed to learn more about the best way to perform oral care. Standard descriptive statistics were calculated for all baseline information (sociodemographic characteristics). Binary variables were expressed as proportions, and normally distributed continuous variables as means and standard deviations.

CONCLUSION

The poor perception and attitudes of ICU nurses regarding oral care for MV patients require the urgent attention of clinical administrators. In-hospital training regarding oral care protocol could improve nurses' perception and attitudes.
