Prospective study: reducing pressure ulcers in intensive care units at a Turkish medical center

Educational interventions on preventing pressure injuries targeted at nurses: systematic review and meta-analysis

BACKGROUND

Although preventable, pressure injuries are commonly observed in the hospital setting and are estimated to be the third most costly condition, after cancer and cardiovascular disease.

AIM

Nurses play a crucial role in the prevention and management of pressure injuries, however, published evidence on the effectiveness of educational interventions, directed specifically at nurses in the hospital environment, is scarce.

METHOD

The authors retrieved published studies on the subject from selected databases (Pubmed/Medline, Embase, Web of Science and the Cochrane Library) in a number of languages (Portuguese, English, French and Spanish). The search yielded randomised controlled trials, as well as quasi-experimental and comparative studies.

FINDINGS

In total, 11 studies were selected. The outcomes analysed, following some type of educational intervention, included the attitudes and knowledge of the nursing professionals, as well as the incidence of pressure injuries.

CONCLUSION

The present study demonstrated that different educational strategies can help prevent pressure injuries in the hospital environment.

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.

Validity and reliability of the Turkish version of The Pressure Injury Prevention Knowledge Questionnaire(PIPK)

AIM

This study aimed to evaluate the validity and reliability of the Turkish version of the Pressure Injury Prevention Knowledge Questionnaire (PIPK).

METHOD

A methodological study design was used. The instrument was translated into Turkish and back-translated into English. After evaluating the language equivalence and content validity of the scale, test-retest reliability, internal consistency and construct validity were examined. The research was conducted with a total of 324 nurses working in a state hospital and two private hospitals who volunteered to participate in the research. Number, percentage distributions, intraclass correlation coefficient (ICC), Kappa coefficient test, Man Whitney U test and Rasch analysis were used to evaluate the data.

RESULTS

Content validity was evaluated by 11 experts in wound care and the CVI(content validity index was found 0.90. The correlation coefficient between the groups was found to be ICC 0.979 in the Kappa coefficient test performed for the reliability analysis. When the in- and out-of-fit difficulty index values of the scale were examined, it was found that the averages of these values varied between "0.72" and "1.38" values.

CONCLUSIONS

The Pressure Injury Prevention Knowledge Questionnaire (PIPK) was found to be a valid and reliable tool for intercultural studies revealing the nursing knowledge of prevention on PIs. It is recommended to conduct studies that test the validity and reliability of the scale in different samples.

Determination of nurses' level of knowledge on the prevention of pressure ulcers: The case of Turkey

AIM OF THE STUDY

Pressure ulcers (PUs) constitute a health issue that has a high prevalence and incidence rate in acute and long-term care, requiring long-term nursing care for treatment and prevention. Therefore, nurses should have adequate knowledge of the interventions and practices used to prevent PUs.

MATERIALS AND METHODS

This study employed a descriptive and cross-sectional design to assess the level of nurses' knowledge concerning preventive interventions for PUs. Based on data found in the literature, researchers developed a 16-question Participant Information Form (including age, gender, level of education, employed ward, and training on PUs) and used this form, along with the Turkish version of the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI-T), to collect data.

RESULTS

A group of 471 nurses working in two foundation hospitals in 2018 participated in the study by completing a questionnaire. Among the participants, 44.2% worked in surgery, 21.2% in internal medicine, and 34.6% in other wards (such as intensive care, pediatrics, and the operating theater). Most of the nurses(73.5%) held a bachelor's degree, and their average work experience was 7.27 ± 7.00 years. It was determined that 69.4% of the nurses had not received in-service training relating to PUs, 55.6% did not attend lectures/conferences or read articles on the prevention of PUs, and 59.7% rated themselves as "adequate" in interventions used to prevent PUs. Based on the use of PUPKAI-T, 17 individuals (3.6%) scored equal to or more than the 60% cut-off value, and 454 individuals (96.4%) scored less than 60%. The mean level of knowledge on PUs was calculated as 11.1 ± 2.659 (range: 1-18) out of 26 questions.

CONCLUSIONS

Results of the study showed that the general level of knowledge of nurses in preventing PUs are extremely insufficient. Therefore, various strategies should be developed to increase nurses' level of knowledge on the etiology and development, classification and observation, and risk assessment of PUs, as well as on nutrition plans and preventive interventions.

Effectiveness on hospital-acquired pressure ulcers prevention: a systematic review

The effective approach on pressure ulcer (PU) prevention regarding patient safety in the hospital context was evaluated. Studies were identified from searches in EBSCO host, PubMed, and WebofScience databases from 2009 up to December 2018. Studies were selected if they were published in English, French, Portuguese, or Spanish; incidence of PUs was the primary outcome; participants were adults (≥18 years) admitted in hospital wards and/or units. The review included 26 studies. Studies related to prophylactic dressings applied in the sacrum, trochanters, and/or heels, education for health care professionals, and preventive skin care and system reminders on-screen inpatient care plan were effective in decreasing PUs. Most of the studies related to multiple intervention programmes were effective in decreasing PU occurrence. Single interventions, namely support surfaces and repositioning, were not always effective in preventing PUs. Repositioning only was effective when supported by technological pressure-mapping feedback or by a patient positioning system. Risk-assessment tools are not effective in preventing PUs. PUs in the hospital context are still a worldwide issue related to patient safety. Multiple intervention programmes were more effective in decreasing PU occurrence than single interventions in isolation. Single interventions (prophylactic dressings, support surfaces, repositioning, preventive skin care, system reminders, and education for health care professionals) were effective in decreasing PUs, which was always in compliance with other preventive measures. These results provide an overview of effective approaches that should be considered when establishing evidence-based guidelines to hospital health care professionals and administrators for clinical practice effective in preventing PUs.

Efficacy of mummy on healing of pressure ulcers: A randomized controlled clinical trial on hospitalized patients in intensive care unit

Background

Mummy is a mineral substance which according to Persian medicine texts, may be useful in treatment of chronic ulcers.

Objective

The present study was performed with the aim of determining the effect of mummy on healing of pressure in male patients who had been hospitalized due to cerebrospinal injury in the Intensive Care Unit.

Methods

This randomized, placebo-controlled clinical trial was performed on 75 patients who had pressure ulcer at Shahid Bahonar Hospital in Kerman, Iran, from September 2016 to March 2017. The control group received normal saline and routine wound dressing, while the intervention group received mummy water solution 20% in addition to normal saline and routine wound dressing on a daily basis. Data was recorded based on the PUSH method. In both groups, ulcers were evaluated on days 0, 7, 14, 21 and 28 for the variables of ulcer surface area, the amount of exudate and type of tissue. Data analysis was done through SPSS 21 and using t-test, Repeated Measure Analysis, Cox Regression and Chi-square.

Results

Both groups showed reduction in the average ulcer surface area (3.26 to 0.53 in the intervention group and 5.1 to 3.46 in the control group), the average exudate amount (1.26 to 0.26 in the intervention group and 1.83 to 1.06 in the control group) and the average tissue score (1.36 to 0.23 in the intervention group and 2.13 to 1.26 in the control group). Over the entire study period, the intervention group showed more acceptable signs of healing compared to the control group (p<0.05).

Conclusion

The healing process was more prominent in the intervention group than the control group.

Clinical trial registration

The trial was registered at the Iranian Registry of Clinical Trials with registered NO. (IRCT2014042917494N1) (29/04/2014).

The Validity and Reliability of the Turkish Version of the Neonatal Skin Risk Assessment Scale

PURPOSE

The study created a Turkish translation of the Neonatal Skin Risk Assessment Scale (NSRAS) that was developed by Huffines and Longsdon in 1997. Study authors used a cross-sectional survey design in order to determine the validity and reliability of the Turkish translation.

SUBJECTS AND SETTING

The study was conducted at the neonatal intensive care unit of a university hospital in Ankara between March 15 and June 30, 2014. The research sample included 130 neonatal assessments from 17 patients.

METHODS

Data were collected by questionnaire regarding the characteristics of the participating neonates, 7 nurse observers, and the NSRAS and its subarticles. After translation and back-translation were performed to assess language validity of the scale, necessary corrections were made in line with expert suggestions, and content validity was ensured. Internal consistency of the scale was assessed by its homogeneity, Cronbach's α, and subarticle-general scale grade correlation.

RESULTS

Cronbach's α for the scale overall was .88, and Cronbach's α values for the subarticles were between .83 and .90. Results showed a positive relationship among all the subarticles and the overall NSRAS scale grade (P < .01) with correlation values between 0.333 and 0.721. Explanatory and predicative factor analysis was applied for structural validity. Kaiser-Meyer-Olkin analysis was applied for sample sufficiency, and Bartlett test analysis was applied in order to assess the factor analysis of the sample. The Kaiser-Meyer-Olkin coefficient was 0.73, and the χ value found according to the Bartlett test was statistically significant at an advanced level (P < .05). In the 6 subarticles of the scale and in the general scale total grade, a high, positive, and significant relationship among the grades given by the researcher and the nurse observers was found (P < .05).

CONCLUSION

The Turkish NSRAS is reliable and valid.

The Use of the Braden Scale in Assessing Pressure Ulcers in Turkey: A Systematic Review

OBJECTIVE

The goal of this systematic review was to reach scientific generalizations regarding the assessment of risk for pressure ulcers based on the results of previous studies that made use of the Braden Scale.

DATA SOURCES

This research was performed by using a retrospective screening of studies relevant to the subject. In Turkey, the first validity and reliability study for the Braden Scale was performed by Oğuz and Olgun in 1998. For this reason, the authors' research was conducted between March 2, 2012, and August 4, 2012, as a systematic review analysis by evaluating studies in Turkey that made use of the Braden Scale between 1998 and 2012. Screening was performed by using different combinations of 8 keywords in Turkish and English to scan a total of 10 national and international databases. A total of 2375 studies were evaluated, and 16 studies were included and considered within the context of this research.

RESULTS AND CONCLUSIONS

It was determined that the studies considered within the context of the current research were conducted between 1998 and 2012; 5 of these studies were experimental and 11 were descriptive; the sample size varied between 22 and 422; the majority were performed in intensive care units; and the study samples were mostly composed of patients. The Braden Scale was used in these studies for forming samples by identifying high-risk patients. Two studies evaluated the reliability of the Braden Scale, whereas 7 other studies calculated the reliability coefficient. Only 1 study included results for sensitivity, specificity, positive predictive value, and negative predictive value (which represent the predictive criteria of assessment tools). Four studies indicated cutoff values, which varied between 14 and 18. A general evaluation of these studies' results revealed limited evidence of effective risk assessment by the Braden Scale.

Effectiveness of Pressure Ulcer Prevention Strategies for Adult Patients in Intensive Care Units: A Systematic Review

BACKGROUND

Pressure ulcers are associated with substantial health burden, but could be preventable. Hospital-acquired pressure ulcers (HAPUs) prevention has become a priority for all healthcare settings, as it is considered a sign of quality of care providing. Intensive care unit (ICU) patients are at higher risk for HAPUs development. Despite the availability of published prevention strategies, there is a little evidence about which strategies can be safely integrated into routine standard care and have an impact on HAPUs prevention.

AIMS

The aim was to synthesize the best available evidence regarding the effectiveness of single strategies designed to reduce the incidence and prevalence of HAPUs development in ICUs.

METHODS

The search strategy was designed to retrieve studies published in English across CINAHL, Medline, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Mednar between 2000 and 2015. All adult ICU participants were aged 18 years or over. This review included randomized controlled trials, quasi-experimental and comparative studies. The studies that were selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical-appraisal instruments.

RESULTS

The review included 25 studies, and the meta-analysis revealed a statistically significant effect of a silicon foam dressing strategy in reducing HAPUs incidence (effect size = 4.62; 95% CI: 0.05-0.29; p < .00001, effect size = 4.50; 95% CI: 0.05-0.31; p = .00001, respectively) in critically ill patients. Evidence of the effectiveness of nutrition, skin-care regimen, positioning and repositioning schedule, support surfaces, and the role of education in prevention of HAPUs development in the ICU was limited, which precludes strong conclusions.

LINKING EVIDENCE TO ACTION

The review provides an evidence-based guide to future priorities for clinical practice. In particular, a silicone foam dressing has positive impact in reducing sacrum and heel HAPUs incidence in the ICU.

Predictive capacity of risk assessment scales and clinical judgment for pressure ulcers: a meta-analysis

A systematic review with meta-analysis was completed to determine the capacity of risk assessment scales and nurses' clinical judgment to predict pressure ulcer (PU) development. Electronic databases were searched for prospective studies on the validity and predictive capacity of PUs risk assessment scales published between 1962 and 2010 in English, Spanish, Portuguese, Korean, German, and Greek. We excluded gray literature sources, integrative review articles, and retrospective or cross-sectional studies. The methodological quality of the studies was assessed according to the guidelines of the Critical Appraisal Skills Program. Predictive capacity was measured as relative risk (RR) with 95% confidence intervals. When 2 or more valid original studies were found, a meta-analysis was conducted using a random-effect model and sensitivity analysis. We identified 57 studies, including 31 that included a validation study. We also retrieved 4 studies that tested clinical judgment as a risk prediction factor. Meta-analysis produced the following pooled predictive capacity indicators: Braden (RR = 4.26); Norton (RR = 3.69); Waterlow (RR = 2.66); Cubbin-Jackson (RR = 8.63); EMINA (RR = 6.17); Pressure Sore Predictor Scale (RR = 21.4); and clinical judgment (RR = 1.89). Pooled analysis of 11 studies found adequate risk prediction capacity in various clinical settings; the Braden, Norton, EMINA (mEntal state, Mobility, Incontinence, Nutrition, Activity), Waterlow, and Cubbin-Jackson scales showed the highest predictive capacity. The clinical judgment of nurses was found to achieve inadequate predictive capacity when used alone, and should be used in combination with a validated scale.

Evidence-based prevention of pressure ulcers in the intensive care unit

The development of stage III or IV pressure ulcers is currently considered a never event. Critical care patients are at high risk for development of pressure ulcers because of the increased use of devices, hemodynamic instability, and the use of vasoactive medications. This article addresses risk factors, risk scales such as the Norden, Braden, Waterlow, and Jackson-Cubbin scales used to determine the risk of pressure ulcers in critical care patients, and prevention of device-related pressure ulcers in patients in the critical care unit.

Preventing pressure ulcers in hospitals: A systematic review of nurse-focused quality improvement interventions

BACKGROUND

A systematic review of the literature on nurse-focused interventions conducted in the hospital setting informs the evidence base for implementation of pressure ulcer (PU) prevention programs. Despite the availability of published guidelines, there is little evidence about which interventions can be successfully integrated into routine care through quality improvement (QI). The two previous literature syntheses on PU prevention have included articles from multiple settings but have not focused specifically on QI.

METHODS

A search of six electronic databases for publications from January 1990 to September 2009 was conducted. Trial registries and bibliographies of retrieved studies and reviews, and Internet sites of funding agencies were also searched. Using standardized forms, two independent reviewers screened publications for eligibility into the sample; data were abstracted and study quality was assessed for those that passed screening.

FINDINGS

Thirty-nine studies met the inclusion criteria. Most of them used a before-and-after study design in a single site. Intervention strategies included PU-specific changes in combination with educational and/or QI strategies. Most studies reported patient outcome measures, while fewer reported nursing process of care measures. For nearly all the studies, the authors concluded that the intervention had a positive effect. The pooled risk difference for developing PUs was -.07 (95% confidence interval [CI]: -0.0976, -0.0418) comparing the pre- and postintervention status.

CONCLUSION

Future research can build the evidence base for implementation through an increased emphasis on understanding the mechanisms by which improved outcomes are achieved and describing the conditions under which specific intervention strategies are likely to succeed or fail.
