Background:
There is a wide variety of preventive methods currently available for the treatment of exposure keratopathy. Because of a lack of evidence from head-to-head randomized controlled trials (RCTs), the relative effects of these preventive methods in exposure keratopathy patients remain unclear. The purpose of our study is to carry out a network meta-analysis comparing the efficacy of different methods for the prevention of exposure keratopathy and rank these nursing methods for practical consideration.
Methods:
A literature search was performed of the MEDLINE (PubMed), EMBASE, Web of Science, China National Knowledge Infrastructure Library (CNKI), China Science and Technology Journal Database (Weipu), WanFang Database and China Biology Medicine disc. Two authors independently extracted data from each included RCTs according to a predesigned Excel spreadsheet and assessed the methodological quality of included RCTs using the Cochrane risk of bias tool. Data was analyzed using the R (V.3.6.2) and the Stata (V.15.0).
Results:
21 RCTs involving 2022 patients and evaluating 11 preventive methods were included. Rankings based on posterior probabilities revealed that artificial tear ointment might be the best way to prevent exposure keratopathy (35%), polyethylene covers might be the second-best (31%), swimming goggles might be the third-best (21%), foam dressing might be the fourth-best (18%).
Conclusions:
This network meta-analysis indicated that artificial tear ointment, polyethylene covers, swimming goggles and foam dressing might be selected for the prevention of exposure keratopathy in intensive care unit patients, which is important in future research. Although evidence is scant, more attention should be paid to head-to-head comparisons of the most commonly used prevention methods in this field.
