Incidence and characteristics of hospital-acquired mucous membrane pressure injury: A five-year analysis

Incidence and characteristics of device-related pressure injuries in intensive care: A four-year analysis

OBJECTIVES

To describe and analyse the incidence and characteristics of intensive care-acquired device-related pressure injuries.

DESIGN

Secondary data analysis of intensive care-acquired pressure injuries during 2019-2022.

SETTING

Single general intensive care unit in Brisbane, Australia.

MAIN OUTCOME MEASURES

Intensive care-acquired pressure injury incidence, device-related pressure injury incidence, non-device-related pressure injury incidence, pressure injury category and location, device associated with pressure injury.

RESULTS

During the 4-year period, there were 7343 intensive care admissions of whom 413 (5.6 %) patients developed an intensive care-acquired pressure injury. The incidence of device-related pressure injury was 4.0 % compared to 2.7 % non-device-related pressure injury. In total there were 461 device-related pressure injuries, which were mostly (55 %) associated with endotracheal tubes or the methods used to secure them. Consequently, the majority of injuries were found on the mucous membranes (lips, mouth and tongue). The other main devices associated with injuries were high-flow nasal prongs (9.3 %), indwelling urinary catheters (6.7 %), nasogastric tubes (6.5 %) and oxygen masks (5.0 %). Overall, device-related pressure injuries were less severe than non-device-related pressure injuries, however they occurred in a shorter time frame (median 4 days versus 6 days). A range of factors was associated with device-related pressure injuries but overall, their presence or duration was less than with non-device-related pressure injuries.

CONCLUSION

The study results provide rigorous evidence of the incidence and characteristics of device-related pressures injuries, that can be used to benchmark with other intensive care units nationally and internationally.

IMPLICATIONS FOR CLINICAL PRACTICE

Endotracheal tube-associated pressure injuries were the most common type of device-related injury, providing a clear focus for preventative intervention. Given the high proportion of these device-related injuries, effective interventions would have a significant impact on overall reduction of intensive care-acquired pressure injuries. Since most injuries occur within three days of device insertion, early preventative intervention is time-critical.

Development and validation of a nomogram for oral mucosal membrane pressure injuries in ICU patients: A prospective cohort study

AIMS

Establishing a nomogram to estimate the probability of oral mucosal membrane pressure injury of endotracheal tube-intubated hospitalized patients in intensive care unit.

DESIGN

Multicentre prospective cohort study.

METHODS

Using Lasso regression and COX regression, variable selection was performed on demographic, clinical and laboratory data of 1037 ICU endotracheal tube-intubated hospitalized patients from West China Hospital, to construct a nomogram. External validation was conducted on 484 ICU endotracheal tube-intubated patients from People's Hospital of Zhongjiang County.

RESULTS

Among 38 potential predictors, five variables emerged as independent predictors, integrated into the nomogram: administration of antibiotics, nutritional therapy duration, agitation, hypotension and albumin levels.

CONCLUSIONS

We established a nomogram based on the hospital characteristics of ICU endotracheal tube-intubated patients, aiding in the prediction of the occurrence of oral mucosal membrane pressure injury.

REPORTING METHOD

The study followed TRIPOD guidelines.

RELEVANCE TO CLINICAL PRACTICE

The nomogram we developed can assist clinical worker in better identifying at-risk patients and risk factors. It enables the implementation of evidence-based nursing interventions in care to prevent the development of oral mucosal membrane pressure injury.

TRIAL REGISTRATION

The study has been registered with the Chinese Clinical Trial Registry (http://www.chictr.org.cn) under registration number ChiCTR2200056615.

Characteristics of oral mucosal pressure injuries in children with orotracheal intubation in intensive care units: An observational study

BACKGROUND

Tracheal intubation can be used for ventilation to ensure an unobstructed respiratory tract, and it is the most common respiratory support technique used in paediatric intensive care unit (PICU) patients. Orotracheal intubation is usually the preferred method of tracheal intubation. However, it can cause stress-related damage to the oral mucosa. Identifying the factors that cause oral mucosal pressure injury (OMPI) can prevent its occurrence in children with oral endotracheal intubation.

AIMS

To examine the characteristics of OMPI in children who underwent orotracheal intubation in the PICU and to assess their influencing factors.

STUDY DESIGN

An observational, prospective study. Data were gathered from the PICU of a tertiary hospital in China between January 2023 and October 2023. The patient data were obtained from the 'General Information Questionnaire', 'Paediatric Critical Illness Score', 'STRONGkids Scale' and 'OMPI Staging and Assessment Tools'. Data analysis was subsequently performed using univariate and logistic regression analyses.

RESULTS

A total of 187 children who underwent orotracheal intubation were analysed. During the observation period, 44.92% (n = 84) of the children developed OMPI. It comprised 63.10% (n = 53) of stage I injuries, 33.33% (n = 28) of stage II injuries and 3.57% (n = 3) of stage III injuries. The common injury sites were the lower jaw (48.81%), upper jaw (29.76%), tongue (20.24%) and joints (10.71%). The logistic regression analysis results revealed that high critical illness (OR = 0.835, 95% CI: 0.726-0.961), long intubation time (OR = 1.043, 95% CI: 1.021-1.067), prone ventilation (OR = 6.708, 95% CI: 1.421-31.670), hypothermia (OR = 5.831, 95% CI: 1.208-28.149), use of dental pads (OR = 5.520, 95% CI: 1.150-26.487) and low albumin levels (OR = 6.238, 95% CI: 1.285-30.281) were the main contributing factors for OMPI in children with orotracheal intubation (p < .05).

CONCLUSIONS

The occurrence of OMPI in children who underwent orotracheal intubation in the PICU was notable and was predominantly observed in stages I and II. Consequently, clinical nursing personnel should proactively recognize risk factors and administer timely interventions to mitigate the occurrence of OMPI in such children.

RELEVANCE TO CLINICAL PRACTICE

The incidence of OMPI in children who underwent orotracheal intubation was relatively high. Nurses and doctors should closely monitor the risk factors for orotracheal intubation in children to prevent the occurrence of OMPI.

Assessment of pressure injury risk in intensive care using the COMHON index: An interrater reliability study

OBJECTIVES

To assess the interrater reliability of the COMHON (level of COnciousness, Mobility, Haemodynamics, Oxygenation, Nutrition) Index pressure injury risk assessment tool.

DESIGN

Interrater reliability was tested. Twenty-five intensive care patients were each assessed by five different nurse-raters from a pool of intensive care nurses who were available on the days of assessment. In total, 25 nurses participated.

SETTING

Two general and one cardiovascular surgery intensive care units in Istanbul, Turkey.

MAIN OUTCOME MEASURES

Interrater reliability was analysed using intraclass correlations, and standard errors of measurement (SEM) were calculated for sum scores, risk level and item scores. Minimally detectable change (MDC) was also calculated for sum score. Consistency between paired raters was analysed using Pearson's Product Moment Correlation (r) for sum score and Spearman's rho (rs) for ordinal variables.

RESULTS

All assessments were completed in ≤5 min. Interrater reliability was very high [ICC (1,1) = 0.998 (95 % CI 0.996 - 0.999)] with a SEM of 0.14 and MDC of 0.39. Consistency between paired raters was strong for sum and item scores and risk levels (coefficients >0.6). All scale items showed correlations of >.3 with the sum score.

CONCLUSION

The results demonstrate near-perfect interrater reliability. Further research into the psychometric properties of the COMHON Index and its impact on preventative intervention use is warranted.

IMPLICATIONS FOR CLINICAL PRACTICE

Pressure injury risk assessment within intensive care should be setting-specific due to the unique risk factors inherent to the patient population, which are not considered by general pressure injury risk assessment tools. An intensive care-specific pressure injury risk assessment tool was tested and demonstrated high reliability between intensive care nurses. Further research is needed to understand how its use in practice affects preventative intervention implementation and, in turn, how it impacts pressure injury outcomes.

Mucosal membrane pressure injury in intensive care units: A scoping review

AIM

To describe published work on the current situation of mucosal membrane pressure injury of patients in the intensive care unit.

BACKGROUND

Device-related pressure injuries in critically ill patients are mostly focused on skin surface injuries, and less attention is paid to mucosal membrane pressure injury.

METHODS

We searched PubMed, Embase, Web of Science, CINAHL, and Cochrane Library from database construction until March 1, 2023. Two researchers independently screened and extracted data.

RESULTS

Eighteen articles met our criteria and were published in 2014-2023. The included studies showed that the incidence of mucosal membrane pressure injury in critically ill patients ranged from 0.83% to 88.2%, and the prevalence ranged from 0.16% to 55.6%. The most frequently reported site of mucosal injury is the oral mucosa, followed by the nasal mucosa. Ten studies used Braden to assess the risk of mucosal membrane pressure injury, and only six studies reported specific stages of mucosal membrane pressure injury. Thirteen studies described 30 risk factors for mucosal membrane pressure injury, with albumin being the most frequently reported risk factor, followed by the vasoconstrictive drugs use. Thirty risk factors were summarized in six aspects: medical device-related factors, disease-related factors, treatment- related factors, physiological and biochemical parameters, demographic-related factors, and microbial colonisation.

CONCLUSIONS

The incidence or prevalence of mucosal membrane pressure injury varies widely, and specific risk assessment tools and standardized staging criteria need to be further determined. The risk factors of mucosal membrane pressure injury involve multiple aspects, and some risk factors have only been explored in few studies and need to be further verified, in order to detect the risk group of mucosal membrane pressure injury early and take targeted preventive measures.

IMPLICATIONS FOR CLINICAL PRACTICE

We synthesized the current research status of mucosal membrane pressure injury in critically ill patients, which can provide a valuable reference for the clinical staff to develop preventive and management measures for such patients.
