Effectiveness of interventions to prevent pressure injury in adults admitted to acute hospital settings: A systematic review and meta-analysis of randomised controlled trials

Nurses' Perspectives on the Use of Prophylactic Dressings to Prevent Pressure Injury: A Qualitative Study

AIM

To understand, from a nursing perspective, factors affecting the use of prophylactic dressings to prevent pressure injuries in acute hospitalised adults.

BACKGROUND

Pressure injury causes harm to patients and incurs significant costs to health services. Significant emphasis is placed on their prevention. Relatively recently, prophylactic dressings have been promoted to reduce pressure injury development. However, in the acute care setting, information about the clinical use of these dressing is lacking.

DESIGN

Qualitative, descriptive.

METHODS

Nineteen medical and surgical nurses participated. Semi-structured interviews were conducted and transcribed verbatim. Thematic analysis was performed using an inductive approach using NVivo software.

RESULTS

Three themes were identified, reflecting factors that influenced and perpetuated indiscriminate use of prophylactic dressings: False sense of security; Convenience and task prioritisation; and Navigating challenges in evidence-based pressure injury prevention.

CONCLUSIONS

The findings indicate inconsistent prevention practices, with prophylactic dressings often applied without justification or referral to research-based evidence to guide clinical decision-making. There was a prevailing attitude of 'job done' when a prophylactic dressing was applied.

IMPACT

This study has identified several factors that perpetuate the inappropriate use of prophylactic dressings for pressure injury prevention that may be amenable to organisational change. The findings indicate that nurses often rely on these dressings as a shortcut due to time constraints, which led to missed skin assessments and low-value care. The research can be used to inform the development of clear guidelines on dressings within hospital settings which encourage assessment-based selection for their use, and process-based guidance for their application, skin surveillance, dressing inspection and removal.

REPORTING METHOD

The Consolidated Criteria for Reporting Qualitative Research (COREQ) reporting guideline was followed.

National improvements in falls and pressure injuries in Swiss hospitals from 2011 to 2022: A secondary data analysis of national quality monitoring data

INTRODUCTION

National quality monitoring in healthcare and, in particular, the (transparent) comparison of results can trigger improvements at the structural and procedural levels and, thus, improve the outcome. In Switzerland, this kind of monitoring was conducted between 2011 and 2022 (except 2020 and 2021 due to the COVID-19 pandemic) for falls and pressure injuries in the hospital setting. The aim of this study was to examine the improvements in the quality of care for falls and pressure injuries in Swiss hospitals during the monitoring period.

METHOD

A secondary data analysis was conducted of the Swiss national quality monitoring data on falls and pressure injuries based on a multicenter cross-sectional design. Descriptive data analysis was performed.

RESULTS

The hospital-acquired pressure injury prevalence rate varied between 3.6% and 5.8%, and the in-hospital fall rate was between 3.0% and 4.6%. The prevalence rates showed their greatest decrease after the first monitoring, with only a slight decrease/stagnation observed thereafter. An increase in prevalence rates was revealed after the two-year monitoring break due to the COVID-19 pandemic. The structural conditions improved (e.g., implementation of guidelines) and more processes were implemented at the patient level (e.g., use of preventive measures) over the monitoring period. At the same time, patients tended to be older, more multimorbid, and more at risk of pressure injuries.

CONCLUSION

Considering the change in the patient population (higher risk) and the findings on the structure and process indicators, the improvement in quality of care is likely to be more pronounced than the prevalence rates suggest.

Prophylactic Interventions for Heel Pressure Ulcers in Critically Ill Patients Admitted to an Intensive Care Unit: A Systematic Review and Meta-Analysis

Pressure ulcers are one of the most predictable adverse events, and nurses play a major role in their prevention. Patients receiving intensive care are at a particularly high risk of developing pressure ulcers. The heel is a common area for pressure ulcers, but the number of comparative studies on preventing pressure ulcers is small. Therefore, it is important to combine the evidence. This study aimed to investigate the effectiveness of interventions to prevent heel pressure ulcers by comprehensively extracting and quantitatively integrating the results of studies on preventive care for heel pressure ulcers in critically ill patients. Systematic reviews and meta-analyses were performed. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) 2020. Eligible criteria were randomized controlled trials (RCTs) and non-RCTs examining interventions for the prevention of heel pressure ulcers as an adjunct to standard care in critically ill adult patients in intensive care units. According to the eligibility and exclusion criteria, two review authors independently screened and extracted data from the included literature. The risk of bias was assessed using the Mixed Methods Appraisal Tool (MMAT). Studies were grouped based on intervention type, and a random-effects meta-analysis was performed. A total of 2,800 studies were searched in four databases. In the primary screening, 122 met the eligibility criteria, and in the secondary screening, seven studies (1,412 patients) met the eligibility criteria. Of the seven studies, three (1,037 eligible patients) applied dressings to the heel, two (237 eligible patients) applied oil, and two (138 eligible patients) wore heel protectors. The risk of bias of the included studies was low. Preventive intervention for heel pressure ulcers significantly reduced the incidence of pressure ulcers compared with usual care (odds ratio (OR) = 0.16, 95% confidence interval (CI) = 0.08-0.33, I² = 0%) In the subgroup analysis, dressing was effective in preventing heel pressure ulcers (three studies, OR = 0.15, 95% CI = 0.05-0.45, I² = 0%). Protector was effective in preventing heel pressure ulcers (two studies, OR = 0.15, 95% CI = 0.05-0.45, I² = 0%). However, oil application was not significantly effective in preventing pressure ulcers (two studies, OR = 0.34, 95% CI = 0.06-1.90, I² = 0%). In this subgroup analysis, oil application alone was ineffective in preventing pressure ulcers. This number of studies is insufficient to draw firm conclusions, and further studies are required.

Barriers and Facilitators to Implementing Pressure Injury Guidelines for Nutrition Assessment and Alternating Pressure Air Mattress Allocation: A Qualitative Study

AIMS

To investigate clinicians' views on barriers and facilitators to implementing pressure injury prevention guideline recommendations for nutrition assessment and treatment, and de-implementing inappropriate alternating pressure air mattress allocation.

DESIGN

A qualitative descriptive study adhering to the COnsolidated criteria for REporting Qualitative research (COREQ) guidelines.

METHODS

We conducted face-to-face or videoconference focus groups and semi-structured individual interviews with clinicians recruited from a metropolitan tertiary hospital. Participants were purposively sampled according to their years of clinical practice. Interview transcripts were thematically analysed inductively to derive barriers and facilitators to guideline uptake. These were then mapped to the Theoretical Domains Framework and behaviour change techniques to inform an evidence-based implementation intervention development to improve guideline uptake.

RESULTS

Thirteen nurses, four occupational therapists and three dietitians were interviewed. Six themes illustrate three guideline-specific barriers and three common facilitators influencing nutrition- and mattress-related guideline uptake. The three barriers were: (1) nurses devalue the use of validated tools in nutrition screening; (2) nurses prioritise vital-sign-related nursing duties over feeding assistance according to clinical urgency; and (3) nurses consider air mattresses a preventative strategy irrespective of patient PI risks. Facilitators to improve guideline uptake were: (1) nurse-led interdisciplinary collaboration, (2) carer involvement and (3) easily accessible updated guidelines. Different Theoretical Domains Framework domains and behaviour change techniques were mapped to the identified nutrition- and mattress-related barriers.

CONCLUSION

The findings highlight three key nurses' attitudinal barriers to nutrition- and mattress-related guideline uptake, which inform the development of theory- and end-user-informed implementation interventions in pressure injury prevention.

IMPLICATIONS

An implementation strategical plan that addresses attitudinal barriers to improving guideline uptake for nutrition assessment and treatment and reducing air mattress overprescription appears critical in developing an intervention to enhance value-based practice, which will need to be evaluated in future trials.

Use of a risk-based intervention bundle to prescribe and implement interventions to prevent pressure injury: An observational study

AIM

To explore the relationship between the prescription and implementation of pressure injury preventative interventions following risk assessment combined with a risk-stratified intervention bundle.

DESIGN

Single-centre, cross-sectional, observational, prospective.

METHODS

The charts and bedsides of 341 adult inpatients were examined. Data collection included pressure injury risk level, prescribed preventative interventions and evidence of intervention implementation.

RESULTS

Most patients (68.6%) were at risk of pressure injury, and most interventions were prescribed according to their risk level. However, evidence from direct observation and/or documentation indicated intervention implementation rates were relatively poor. Of nine interventions mandated for all patients, compliance with three patient-/carer-focused interventions was particularly poor, with evidence indicating they had been implemented for 3%-10% of patients. Also, nutritional screening-related interventions were implemented poorly. Clinically indicated implementation of heel-elevation devices and bariatric equipment was low for at-risk patients, and the implementation of interventions for patients with existing pressure injuries was suboptimal. Significant proportions of several interventions that were observed as having been implemented were not documented as such.

CONCLUSION

While most interventions were prescribed according to patient risk level, the overall implementation of interventions was poor. However, the results may in part be due to failure to document interventions as opposed to omitting them.

IMPLICATIONS FOR PATIENT CARE

Documentation of interventions is crucial as it provides evidence of the care provided. An increased focus on documentation of pressure injury preventative interventions is required, with a clear distinction between prescription and implementation.

IMPACT

The results highlighted several deficiencies in care, particularly relating to evidence of implementation, patient involvement and nutritional screening. The results from this study will be used to inform and improve future pressure injury prevention practice within the study hospital and should be used to inform and benchmark pressure injury preventative practices in other hospitals.

REPORTING METHOD

The study adheres to STROBE guidelines.

The effect of pressure injury prevention care bundles on pressure injuries in hospital patients: A complex intervention systematic review and meta-analysis

BACKGROUND

Numerous interventions for pressure injury prevention have been developed, including care bundles.

OBJECTIVE

To systematically review the effectiveness of pressure injury prevention care bundles on pressure injury prevalence, incidence, and hospital-acquired pressure injury rate in hospitalised patients.

DATA SOURCES

The Medical Literature Analysis and Retrieval System Online (via PubMed), the Cumulative Index to Nursing and Allied Health Literature, EMBASE, Scopus, the Cochrane Library and two registries were searched (from 2009 to September 2023).

STUDY ELIGIBILITY CRITERIA

Randomised controlled trials and non-randomised studies with a comparison group published in English after 2008 were included. Studies reporting on the frequency of pressure injuries where the number of patients was not the numerator or denominator, or where the denominator was not reported, and single subgroups of hospitalised patients were excluded. Educational programmes targeting healthcare professionals and bundles targeting specific types of pressure injuries were excluded.

PARTICIPANTS AND INTERVENTIONS

Bundles with ≥3 components directed towards patients and implemented in ≥2 hospital services were included.

STUDY APPRAISAL AND SYNTHESIS METHODS

Screening, data extraction and risk of bias assessments were undertaken independently by two researchers. Random effects meta-analyses were conducted. The certainty of the body of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation.

RESULTS

Nine studies (seven non-randomised with historical controls; two randomised) conducted in eight countries were included. There were four to eight bundle components; most were core, and only a few were discretionary. Various strategies were used prior to (six studies), during (five studies) and after (two studies) implementation to embed the bundles. The pooled risk ratio for pressure injury prevalence (five non-randomised studies) was 0.55 (95 % confidence intervals 0.29-1.03), and for hospital-acquired pressure injury rate (five non-randomised studies) it was 0.31 (95 % confidence intervals 0.12-0.83). All non-randomised studies were at high risk of bias, with very low certainty of evidence. In the two randomised studies, the care bundles had non-significant effects on hospital-acquired pressure injury incidence density, but data could not be pooled.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

Whilst some studies showed decreases in pressure injuries, this evidence was very low certainty. The potential benefits of adding emerging evidence-based components to bundles should be considered. Future effectiveness studies should include contemporaneous controls and the development of a comprehensive, theory and evidence-informed implementation plan.

TWEETABLE ABSTRACT

Pressure injury prevention care bundles decrease hospital-acquired pressure injuries, but the certainty of this evidence is very low.

Barriers and facilitators to implementing pressure injury prevention and management guidelines in acute care: A mixed-methods systematic review

BACKGROUND

Evidence-based pressure injury prevention and management is a global health service priority. Low uptake of pressure injury guidelines leads to compromised patient outcomes. Understanding clinicians' and patients' views on the barriers and facilitators to implementing guidelines and mapping the identified barriers and facilitators to the Theoretical Domains Framework and behaviour change techniques will inform an end-user and theoretically informed intervention to improve guideline uptake in the acute care setting.

OBJECTIVES

To synthesise quantitative and qualitative evidence on i) hospital clinicians' and inpatients' perceptions and experiences of evidence-based pressure injury practices and ii) barriers and facilitators to implementing guidelines.

DESIGN

A convergent integrated mixed-methods systematic review was conducted using the JBI approach.

DATA SOURCE

English language peer-reviewed studies published from 2009 to August 2022 were identified from MEDLINE, EMBASE, CINAHL, PsycINFO and Cochrane Central Library.

REVIEW METHODS

Included studies reported: i) acute care hospital clinicians' and patients' perceptions and experiences of evidence-based pressure injury practices and ii) barriers and facilitators to implementing guidelines. The Mixed Methods Appraisal Tool was used for critical appraisal. Quantitative data was transformed into qualitised data, then thematically synthesised with qualitative data, comparing clinicians' and patients' views. Barriers and facilitators associated with each main theme were mapped to the Theoretical Domains Framework and allocated to relevant behaviour change techniques.

RESULTS

Fifty-five out of 14,488 studies of variable quality (29 quantitative, 22 qualitative, 4 mixed-methods) met the inclusion criteria. Four main themes represent factors thought to influence the implementation of evidence-based guidelines: 1) nurse-led multidisciplinary care, 2) patient participation in care, 3) practicability of implementation and 4) attitudes towards pressure injury prevention and management. Most barriers identified by clinicians were related to the third theme, whilst for patients, there were multiple barriers under theme 2. Barriers were mainly mapped to the Knowledge domain and Environmental Context and Resources domain and were matched to the behaviour change techniques of "instruction on how to perform a behaviour" and "restructuring the physical environment". Most facilitators mentioned by clinicians and patients were related to themes 1 and 2, respectively, and mapped to the Environmental Context and Resources domain. All patient-related attitudes in theme 4 were facilitators.

CONCLUSIONS

These review findings highlight the most influential factors related to implementing evidence-based pressure injury care from clinicians' and patients' views and mapping these factors to the Theoretical Domains Framework and behaviour change techniques has contributed to developing a stakeholder-tailored implementation intervention in acute care settings.

Prevention of Tracheostomy-Related Pressure Injury: A Systematic Review and Meta-analysis

BACKGROUND

In the critical care environment, individuals who undergo tracheostomy are highly susceptible to tracheostomy-related pressure injuries.

OBJECTIVE

To evaluate the effectiveness of interventions to reduce tracheostomy-related pressure injury in the critical care setting.

METHODS

MEDLINE, Embase, CINAHL, and the Cochrane Library were searched for studies of pediatric or adult patients in intensive care units conducted to evaluate interventions to reduce tracheostomy-related pressure injury. Reviewers independently extracted data on study and patient characteristics, incidence of tracheostomy-related pressure injury, characteristics of the interventions, and outcomes. Study quality was assessed using the Cochrane Collaboration's risk-of-bias criteria.

RESULTS

Ten studies (2 randomized clinical trials, 5 quasi-experimental, 3 observational) involving 2023 critically ill adult and pediatric patients met eligibility criteria. The incidence of tracheostomy-related pressure injury was 17.0% before intervention and 3.5% after intervention, a 79% decrease. Pressure injury most commonly involved skin in the peristomal area and under tracheostomy ties and flanges. Interventions to mitigate risk of tracheostomy-related pressure injury included modifications to tracheostomy flange securement with foam collars, hydrophilic dressings, and extended-length tracheostomy tubes. Interventions were often investigated as part of care bundles, and there was limited standardization of interventions between studies. Meta-analysis supported the benefit of hydrophilic dressings under tracheostomy flanges for decreasing tracheostomy-related pressure injury.

CONCLUSIONS

Use of hydrophilic dressings and foam collars decreases the incidence of tracheostomy-related pressure injury in critically ill patients. Evidence regarding individual interventions is limited by lack of sensitive measurement tools and by use of bundled interventions. Further research is necessary to delineate optimal interventions for preventing tracheostomy-related pressure injury.

Prophylactic sacral protective dressings' effect on preventing pressure injury: A meta-analysis

We performed a meta-analysis to evaluate the effect of prophylactic sacral protective dressings on preventing pressure injury. A systematic literature search up to July 2021 was performed, and 11 studies included 5150 community or hospital-based adult subjects requiring care at the start of the study; 2832 of them were using sacral protective dressings and 2318 were given standard care with no sacral protective dressings. They were reporting relationships between the effects of prophylactic sacral protective dressings on preventing pressure injury. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) to assess the effects of prophylactic sacral protective dressings on preventing pressure injury using the dichotomous method with a random or fixed-effect model. Sacral protective dressings had a significantly lower incidence of pressure injuries (OR, 0.39; 95% CI, 0.28-0.53, P < .001) compared with standard care with no sacral protective dressings in community- or hospital-based adult subjects requiring care. Sacral protective dressings had a significantly lower incidence of pressure injuries compared with standard care with no sacral protective dressings in community- or hospital-based adult subjects requiring care. Further studies are needed to confirm these findings.

Effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

The aim of the study was to investigate the effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings.

REVIEW METHOD USED

This is a systematic review and meta-analysis of randomised controlled trials.

DATA SOURCES

Five databases (CINAHL, MEDLINE, Scopus, Web of Science, and Embase) were searched in mid-2019. Searches were updated (in April 2020) to year end 2019.

REVIEW METHODS

From an overarching systematic review and meta-analysis examining the effectiveness of pressure injury preventative interventions in adults admitted to acute hospital settings, trials conducted in intensive care were separated for an intensive care-specific synthesis. Two reviewers, with a third as an arbitrator, undertook study selection, data extraction, and risk-of-bias assessment. Included trials were grouped by intervention type for narrative synthesis and for random-effects meta-analysis using intention-to-treat data where appropriate.

RESULTS

Overall, 26 trials were included. Ten intervention types were found (support surfaces, prophylactic dressings, positioning, topical preparations, continence management, endotracheal tube securement, heel protection devices, medication, noninvasive ventilation masks, and bundled interventions). All trials, except one, were at high or unclear risk of bias. Four intervention types (endotracheal tube securement, heel protection devices, medication, and noninvasive ventilation masks) comprised single trials. Support surface trials were limited to type (active, reactive, seating, other). Meta-analysis was undertaken for reactive surfaces, but the intervention effect was not significant (risk ratio = 0.24, p = 0.12, I² = 51%). Meta-analyses demonstrated the effectiveness of sacral (risk ratio = 0.22, p < 0.001, I² = 0%) and heel (risk ratio = 0.31, p = 0.02; I² = 0%) prophylactic dressings for pressure injury prevention.

CONCLUSIONS

Only prophylactic sacral and heel dressings demonstrated effectiveness in preventing pressure injury in adults admitted to intensive care settings. Further intensive care-specific trials are required across all intervention types. To minimise bias, we recommend that all future trials are conducted and reported as per relevant guidelines and recommendations.

Comparison of pressure injury risk assessment outcomes using a structured assessment tool versus clinical judgement: A systematic review

BACKGROUND

Whilst performing a pressure injury risk assessment is not in itself preventive, risk status identification is critical to inform the judicious implementation of prevention strategies. Risk assessment is mostly undertaken using a structured tool informed by clinical judgement, though there is a perception that use of clinical judgement alone may be sufficient.

OBJECTIVES

Within acute hospital settings, to identify differences in outcomes (risk status, preventive interventions) following nursing assessment of pressure injury risk when using a structured assessment tool compared to clinical judgement.

DESIGN

Systematic review.

DATA SOURCES

EBSCO CINAHL Complete, EBSCO MEDLINE Complete, Scopus, Web of Science, Ovid EMBASE.

METHODS

Primary research relevant to the objectives was eligible for inclusion. Databases were searched in February 2021 (limits: date 2010-2020, English language, adults). Two reviewers undertook the review process, with a third as arbitrator. Appraisal was undertaken using Joanna Briggs Institute critical appraisal tools. Included studies are synthesised narratively. Reporting is in accordance with the PRISMA Statement.

RESULTS

Five moderate to high-quality studies were included. Synthesis was limited by heterogeneity. Several risk assessment tools and methods of clinical judgement were used. Three studies reported pressure injury risk status using both assessment approaches, but in only one did nurses undertake both. Risk status, as identified by each method, varied and was sometimes contradictory. Three studies reported some elements of preventive intervention prescription and/or implementation following risk assessment, but comparison between approaches was limited.

CONCLUSIONS

Some research suggests that risk status varies across different methods of pressure injury risk assessment, but it is unclear what impact this has on preventive intervention use. Risk status was not well linked to preventive interventions. Research is warranted to examine the influence that each approach to risk assessment alone and combined has on identified risk and preventive intervention prescription and implementation.

REGISTRATION

A protocol was prospectively registered with PROSPERO (CRD42021224747).

Risk factors for heel pressure injury in cardiovascular intensive care unit patients

This study analyzed the risk factors for heel pressure injury in cardiovascular intensive care unit patients with the aim of laying the groundwork for preventive nursing interventions. We conducted a retrospective case‐control study of 92 patients who were admitted to the cardiovascular surgical or medical intensive care unit of a university hospital in South Korea between January and December 2017. Of these patients, 31 and 61 were included to the heel pressure injury group and the non‐heel pressure injury group, respectively. Data on their demographic, disease‐related, and intensive care unit treatment characteristics, as well as the degree of pressure injury, were collected from the hospital's electronic medical records using a standardized form. Cardiac surgery (P < .001), operation time (P = .001), use of a mechanical ventilator (P < .001), use of vasoconstrictors (P < .001), use of sedative drugs (P < .001), and extracorporeal membrane oxygenation treatment (P < .001) were identified as significant risk factors for heel pressure injury. A total of 22 patients (71%) from the heel pressure injury group developed deep tissue injury, and 16 patients (51.6%) who received extracorporeal membrane oxygenation treatment developed heel pressure injury.
