Comparative efficacy of various preventive methods for exposure keratopathy among critically ill patients: A network meta-analysis of randomized controlled trials

The effect of polyethylene cover intervention on ocular surface disorder of intensive care unit patients: a systematic review and meta-analysis

BACKGROUND

Polyethylene covers have been proven to be effective in protecting the eyes in patients with decreased or disappeared blink reflexes, but their advantages compared to other conventional methods are still unclear. This systematic review and meta-analysis study aimed to elucidate the impact of polyethylene covers in the prevention of ocular surface disease (OSD) in patients admitted to the intensive care unit (ICU).

METHODS

We searched the Scopus, PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify randomized controlled trial studies. This study followed the PRISMA guidelines and used the Cochrane Collaboration tool to assess the risk of bias.

RESULTS

The findings were expressed as risk ratio (RR) with 95% confidence intervals. The incidence of OSD in the polyethylene cover group was lower than that in the eye drops group (RR = 0.27; 95% CI (0.07, 1.09), P = 0.07) and adhesive tape group (RR = 0.11, 95%CI (0.04, 0.31), P < 0:0001) but the polyethylene cover group showed no significant difference compared to the eye gel group (RR = 0.79, 95%CI (0.18, 3.51), P = 0.76) and the eye ointment group (RR = 0.85; 95% CI (0.36, 1.99), P = 0.71).

CONCLUSION

This study showed that polyethylene covers, eye gels, and eye ointments had an equal effect on preventing OSD in ICU patients, and eye drops and adhesive tapes were relatively less effective. However, other intervention methods had not been compared due to the small number of articles. Hence, further studies should assess the available methods to choose the best practical method.

Prevalence and risk factors of exposure keratopathy among critically ill patients: A systematic review and meta-analysis

AIMS

To identify the incidence, prevalence and risk factors of exposure keratopathy (EK) among critically ill patients.

DESIGN

Systematic review and meta-analysis, in accordance with the PRISMA 2020 Statement.

METHODS

The Cochrane Library, PubMed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), China Knowledge Resource Integrated Database (CNKI), Chinese Biomedical Database (CBM), Weipu Database (VIP) and WanFang Database were systematically searched from inception to June 2022. Observational studies that reported EK among paediatric and adult critically ill patients were screened and included original articles based on the inclusion criteria. Two reviewers independently completed data extraction and quality assessments. Subgroup analysis investigated potential causes of heterogeneity.

RESULTS

Of the 4508 studies identified, 23 studies involving 3519 subjects were included. The pooled prevalence of EK was 34.0%, and the pooled incidence rate of EK was 23.0%. Risk factors associated with EK in critically ill patients included lagophthalmos, chemosis, eye blinks <5 times per minute, mechanical ventilation, sedation, lower Glasgow Coma Scale (GCS) score and higher Acute Physiology and Chronic Health Evaluation (APACHE) II score.

CONCLUSION

This review shows that EK rates are high in critically ill patients and are influenced by multiple factors. Medical staff should pay more attention to EK in critically ill patients, conduct professional evaluations and implement targeted eye care protocols to reduce its occurrence.

IMPLICATIONS FOR PRACTICE

This study shows the frequency of and multiple risk factors for EK in critically ill patients, which provides evidence-based guidance for nurses to evaluate the risk of EK in critically ill patients and take appropriate precautions to reduce the risk.

PROTOCOL REGISTRATION

The protocol was registered in PROSPERO (https://www.crd.york.ac.uk/prospero/) (CRD42022346964).

Nurses' perceptions of critically ill patients' eye care: a qualitative study in Iran

BACKGROUND

Despite the high prevalence of ocular complications in patients admitted to the intensive care unit (ICU), eye care, as an important component of the care plan, has not received much attention from nurses. To improve the quality of eye care, the challenges and concerns of ICU nurses should be studied deeply. Thus, the present study aimed at exploring the challenges faced by ICU nurses in taking care of patients admitted to the ICU.

METHODS

The present conventional qualitative content analysis study was carried out on 11 nurses and 3 head nurses selected purposefully by observing the maximum variation. The data were collected through face-to-face, in-depth, and semi-structured interviews. All data were recorded, transcribed, and analyzed using the conventional content analysis method proposed by Graneheim and Lundman (Nurse Educ Today 24:105-12, 2004). The Max Q Data software 2020 was run to record the interviews and extract codes from the transcriptions.

RESULTS

The participants' mean age was 37.14 ± 6.41 years and their average work experience in ICU was 10.29 ± 7.63 years. The core category that emerged from data analysis was "the lack of an evidence-based approach", which was subdivided into five categories: "education, the missing link", "nurses' inadequate professional competence", "unsafe nursing care", "organizational requirements", and "difficulty in eye care evaluation".

CONCLUSION

Evidence-based practice plays a minor role in the field of eye care in Iran, despite its critical importance. Thus, the Ministry of Health and Medical Education of Iran is recommended to adapt the clinical guidelines so that more attention is paid to this field.
