Prevalence, prevention, and treatment of pressure ulcers: descriptive study in 89 institutions in the Netherlands

A Mathematical Model of Pressure Ulcer Formation to Facilitate Prevention and Management

Pressure ulcers are a frequent issue involving localized damage to the skin and underlying tissues, commonly arising from prolonged hospitalization and immobilization. This paper introduces a mathematical model designed to elucidate the mechanics behind pressure ulcer formation, aiming to predict its occurrence and assist in its prevention. Utilizing differential geometry and elasticity theory, the model represents human skin and simulates its deformation under pressure. Additionally, a system of ordinary differential equations is employed to predict the outcomes of these deformations, estimating the cellular death rate in skin tissues and underlying layers. The model also incorporates changes in blood flow resulting from alterations in skin geometry. This comprehensive approach provides new insights into the optimal bed surfaces required to prevent pressure ulcers and offers a general predictive method to aid healthcare personnel in making informed decisions for at-risk patients. Compared to existing models in the literature, our model delivers a more thorough prediction method that aligns well with current data. It can forecast the time required for an immobilized individual to develop an ulcer in various body parts, considering different initial health conditions and treatment strategies.

Exploring the Multifaceted Potential of Sildenafil in Medicine

Phosphodiesterase type 5 (PDE5) is pivotal in cellular signalling, regulating cyclic guanosine monophosphate (cGMP) levels crucial for smooth muscle relaxation and vasodilation. By targeting cGMP for degradation, PDE5 inhibits sustained vasodilation. PDE5 operates in diverse anatomical regions, with its upregulation linked to various pathologies, including cancer and neurodegenerative diseases. Sildenafil, a selective PDE5 inhibitor, is prescribed for erectile dysfunction and pulmonary arterial hypertension. However, considering the extensive roles of PDE5, sildenafil might be useful in other pathologies. This review aims to comprehensively explore sildenafil's therapeutic potential across medicine, addressing a gap in the current literature. Recognising sildenafil's broader potential may unveil new treatment avenues, optimising existing approaches and broadening its clinical application.

Pressure Ulcers-A Longstanding Problem: A 7-Year Neurorehabilitation Unit Experience of Management, Care, and Clinical Outcomes

BACKGROUND

Neurological disease patients present an increased risk of developing pressure ulcers. The primary aim of this study is to evaluate the incidence and prevalence of pressure ulcers and their impact on length of stay and functional recovery.

METHODS

A retrospective study was conducted in a neurorehabilitation unit over a seven-year period. Data collected include demographic data, length of stay, functional evaluation, risk of pressure ulcers development, nutritional status, and skin. Pressure ulcers were classified according to the European Pressure Ulcer Advisory Panel System.

RESULTS

Data from 816 patients were analyzed. On admission, the authors found 236 pressure ulcers in 131 patients (about 16%), divided into stage I (25%), stage II (50%), and stage III-IV (25%). The most common sites were the heel (36%) and sacrum (29%). Among the risk factors for the development of pressure ulcers, malnutrition played a significant role, with approximately 76% of patients with pressure ulcers having mild to moderate malnutrition.

CONCLUSION

The presence of pressure ulcers seems to have a negative impact on the functional recovery of patients, as shown by the outcome scales and the average length of stay: 51 days versus 36 days (p < 0.01).

The effects of educational intervention on patient participation in pressure injury prevention: a pilot study

OBJECTIVE

Patients' roles in reducing pressure injuries (PIs) are emphasised in clinical guidelines, although patients' preferences are undetermined. This study evaluated the effects of a pilot six-month educational intervention on patient participation in PI prevention.

METHOD

A convenience sampling method was used to select patients admitted to medical-surgical wards at one of the teaching hospitals in Tabriz, Iran. This is a one-group pre-test and post-test interventional study, conducted via quasi-experimental design. Using a pamphlet, patients received education in preventing PIs. Data collected before and after intervention through a questionnaire were analysed using descriptive and inferential statistics (McNemar and paired t-tests) in SPSS software (IBM Corp., US).

RESULTS

The study cohort consisted of 153 patients. Findings revealed that the knowledge of the patients about PIs, patients' ability to talk with the nurses, information received about PIs, and patients' ability to participate in decisions related to PI prevention had significantly increased following the intervention (p<0.001).

CONCLUSION

Educating patients can improve their knowledge to enable them to participate in PI prevention. The findings of this study suggests further research is necessary on factors influencing patients' participation in such self-care behaviours.

Repositioning Practice of Bedridden Patients: An Evolutionary Concept Analysis

Introduction

Repositioning practice is an essential pressure ulcer prevention intervention that has emerged in the history of nursing. Numerous terms are employed to indicate its meaning, such as turning, positioning, or posturing. However, there is no available analysis that distinguishes these terms or analyzes repositioning practice attributes.

Objective

To analyze repositioning practice as a concept of bedridden patients in hospitals by combining methods from Foucault's archeology of knowledge and Rodger's concept analysis.

Concept Description

Repositioning practice passes through three eras: classical, modern, and research. The repositioning practice is “turn a bedridden patient in a harmonized way and ends with anchor and documentation.” The analysis concludes seven attributes for the repositioning practice: pre-turn, assessment, turn, harmonization, anchor, documentation, and time. The analysis assumes bedridden patients, and assigned nurses on duty are the antecedents. Moreover, the main consequence is pressure ulcer prevention, while patient safety and quality of care are the secondary consequences.

Discussion

Repositioning practice understanding has grown with time. Each era has added to or removed from nursing's understanding for repositioning practice until it appears as it now. The current analysis expects further development in repositioning practice understanding and applications.

Conclusion

Repositioning practice is an important nursing intervention and has shown a dynamic movement over history. It is expected that this dynamic will continue in the future.

Introduction&#160;: Pediatric patients are particularly vulnerable to pressure ulcers. Structured evaluation with a risk assessment tool is recommended in order to identify patients at risk. The Braden QD Scale integrates the risks of both immobility-related and medical device-related pressure ulcers in pediatric patients.Objectives&#160;: To translate and pretest the Braden QD Scale into French (Swiss-French version), and to evaluate its consistency, convergent validity, feasibility, and clinical utility.Method&#160;: Over five prevalence surveys, the Braden QD Scale was used on all hospitalized pediatric patients. Convergent validity and internal consistency were tested. A self-administered questionnaire on feasibility and clinical utility was completed by nurses.Results&#160;: The translated version of the Braden QD Scale was pretested on 352 children. The prevalence surveys showed that 5.1% were at risk of developing pressure ulcers. Medical devices were present in 85.8% of cases. A Cronbach&#8217;s alpha of 0.710 and a high convergent validity were measured. High scores of feasibility and clinical utility were found.Discussion and conclusion&#160;: This study suggests that the Swiss-French version of the Braden QD Scale is reliable, valid, feasible, and has clinical utility.

The prevalence of pressure ulcers in Europe, what does the European data tell us: a systematic review

OBJECTIVE

The main aim of this systematic review was to establish the prevalence of pressure ulcers (PU) within published studies from Europe.

METHOD

Using systematic review methodology, quantitative design studies which explored prevalence data and/or the epidemiology of PUs in Europe were considered. The primary outcome was PU prevalence. The search, conducted in April 2019, using Cochrane, Medline, Embase, CINAHL, PubMed, Scopus and Web of Science databases, returned 3065 records, of which 79 met the inclusion criteria. Data were extracted using a pre-designed extraction tool, and validity analysis was undertaken using the Evidence-Based Librarianship (EBL) Critical Appraisal Checklist.

RESULTS

We included 79 articles in this review. Across the studies, the median prevalence was 10.8% (standard deviation: 7%; range: 4.6-27.2%). The highest PU prevalence reported was from the Netherlands (27.2%; n=17,494 participants), and the lowest was reported from Finland (4.6%; n=629 participants). Almost 32.4% (n=151,195) of the PUs were category I and the most common site for PUs was the sacrum.

CONCLUSION

The prevalence data is consistently high. These data indicate the continued need for further resource allocation into PU prevention and management.

Prevalence of pressure ulcers in long-term care: a global review

Objective:

To identify and update the prevalence and incidence of pressure ulcers (PUs) in several countries, in people with long-term conditions resident in care homes or nursing homes.

Methods:

We followed the PRISMA guideline for systematic reviews. However, due to funding constraints we do not claim this review to be systematic but it is a narrative review informed by PRISMA. Medline, Embase and CINHAL were searched for observational studies reporting incidence or prevalence data. Data reported relevant head-to-toe examination of PUs in residence in care or nursing homes. Internal and external validity of the included studies were assessed using the checklist devised by Hoy et al. 1

Results:

Inclusion criteria was met by 17 studies and included in the study. Some studies gave a full breakdown by category, some only gave overall figures, and others excluded category I PUs. However, within those constraints certain patterns are clear. Prevalence rates varied from 3.4–32.4%. Large differences in prevalence in different countries were not explained by methodological differences. While some countries, such as Germany, the Netherlands and the US had robust data, other countries, such as the UK, had none.

Conclusion:

PUs are a common problem in long-term care. However, there are substantial differences between countries and many countries have no published data.

Nursing records, prevention measures and incidence of pressure ulcers in an Intensive Care Unit

OBJECTIVES

The aim of this paper is to determine the incidence and most incident pressure ulcers (PU) category. Establish the main clinical characteristics of these PU. Determine whether there is adequate documentation of PU and of the measures used to prevent them.

METHOD

Observational descriptive and retrospective study during 2014 at Intensive Care Unit (ICU)-University Hospital of Araba. Study sample, all patients suffering from PU at the time of the study by accidental sampling. Computerised records regarding risk assessment, clinical assessment and pressure sore treatment, provided by the 'Metavision' computer programme and descriptive statistics using SPSS version 22.0. Approval from the Ethics Committee for Clinical Research of the University Hospital of Araba was obtained.

RESULTS

The incidence of patients suffering from PU during 2014 was 6.78%. The most common locations for PU were the sacral region and the heels: the most incident pressure ulcers category was grade II, followed by grade I. Out of the 98 PU treated in our patients, 43 occurred outside the ICU and 55 in the unit itself. The lack of records, in all the variables described about PU, was 19.10%.

CONCLUSIONS

The incidence of pressure ulcers was lower than in the current literature. The most frequent category, location and clinical characteristics are comparable to previous studies. There is a high rate of failing to record the characteristics of the PU declared. Good PU prevention measures and recording were carried out.

Comparison of Two Intervention Strategies on Prevention of Bedsores among the Bedridden Patients: A Quasi Experimental Community-based Trial

BACKGROUND

More than 80% of bedridden patients develop bedsores in home care settings. Training of informal caregivers can significantly affect the quality of care to these patients.

OBJECTIVE

The objective of this study is to compare the effectiveness of two caregiver training strategies on prevention of bedsores among bedridden patients.

METHODS

The study was carried out in Chandigarh. The study center was at PGIMER, Chandigarh. Seventy-eight bedridden patients being taken care in their homes were identified. These were randomly allocated into two groups. Group A received Prevention Package I, i.e., self-instruction Manual (SIM), training, and counseling. Group B received Prevention Package 2, i.e., only SIM. All these patients were followed up periodically for 1 year. During each follow-up, patients were observed for bedsore development. Braden scale was used to assess the risk factors of bedsores. Katz scale was used to evaluate the level of functional dependence of patients. Descriptive statistics was used to analyze the data.

RESULTS

The percentage reduction of number of patients at risk of bedsore development as per various domains of Braden Scale was more in Group A as compared to Group B on each successive visit. There was 100% improvement in mobility level in the patients who were totally dependent in both the groups. However, in moderately dependant patients, the improvement in mobility level was more (87%) in Group A as compared to Group B (75%). All the caregivers complied fully with instructions postintervention.

CONCLUSION

Training of caregivers for the prevention of bedsores among the bedridden patients was effective in improving the practices of the caregivers and also in reducing the risk factors of bedsores. One-to-one training with SIM distribution yielded better results than the use of only SIM.

Racial and ethnic disparities in the healing of pressure ulcers present at nursing home admission

BACKGROUND

Pressure ulcers increase the risk of costly hospitalization and mortality of nursing home residents, so timely healing is important. Disparities in healthcare have been identified in the nursing home population but little is known about disparities in the healing of pressure ulcers.

PURPOSE

To assess racial and ethnic disparities in the healing of pressure ulcers present at nursing home admission. Multi-levels predictors, at the individual resident, nursing home, and community/Census tract level, were examined in three large data sets.

METHODS

Minimum Data Set records of older individuals admitted to one of 439 nursing homes of a national, for-profit chain over three years with a stages 2-4 pressure ulcer (n=10,861) were searched to the 90-day assessment for the first record showing pressure ulcer healing. Predictors of pressure ulcer healing were analyzed for White admissions first using logistic regression. The Peters-Belson method was used to assess racial or ethnic disparities among minority group admissions.

RESULTS

A significantly smaller proportion of Black nursing home admissions had their pressure ulcer heal than expected had they been part of the White group. There were no disparities in pressure ulcer healing disadvantaging other minority groups. Significant predictors of a nonhealing of pressure ulcer were greater deficits in activities of daily living and pressure ulcer severity.

CONCLUSIONS

Reducing disparities in pressure ulcer healing is needed for Blacks admitted to nursing homes. Knowledge of disparities in pressure ulcer healing can direct interventions aiming to achieve equity in healthcare for a growing number of minority nursing home admissions.

Effects of Electrical Stimulation on Risk Factors for Developing Pressure Ulcers in People with a Spinal Cord Injury: A Focused Review of Literature

Pressure ulcers (PUs) are a common and serious problem for wheelchair users, such as individuals with a spinal cord injury (SCI), resulting in great discomfort, loss of quality of life, and significant medical care costs. Therefore, it is of utmost importance to prevent PUs. In this literature overview, the effects of electrical stimulation (ES) on the risk factors for developing PUs in people with an SCI are examined and synthesized from January 1980 to January 2015. Thirty-four relevant studies of PU prevention in SCI were identified. Four were randomized clinical trials, 24 were case series, 6 had other designs. Three types of ES modalities were identified. The methodological quality varied from poor to fairly strong, with a large variety in used ES parameters. Twenty-three studies were identified describing short-term effects of ES on interface pressure, oxygenation, and/or blood flow, and 24 studies described the long-term effects of ES on muscle volume, muscle strength, and histology. Whereas there is a lack of controlled studies on the effects of ES on PU incidence, which disallows definite conclusions, there is moderate evidence to suggest that ES-induced muscle activation has a positive influence on several risk factors for developing PUs in people with an SCI.

Relationship between the presence of baccalaureate-educated RNs and quality of care: a cross-sectional study in Dutch long-term care facilities

BACKGROUND

Recent evidence suggests that an increase in baccalaureate-educated registered nurses (BRNs) leads to better quality of care in hospitals. For geriatric long-term care facilities such as nursing homes, this relationship is less clear. Most studies assessing the relationship between nurse staffing and quality of care in long-term care facilities are US-based, and only a few have focused on the unique contribution of registered nurses. In this study, we focus on BRNs, as they are expected to serve as role models and change agents, while little is known about their unique contribution to quality of care in long-term care facilities.

METHODS

We conducted a cross-sectional study among 282 wards and 6,145 residents from 95 Dutch long-term care facilities. The relationship between the presence of BRNs in wards and quality of care was assessed, controlling for background characteristics, i.e. ward size, and residents' age, gender, length of stay, comorbidities, and care dependency status. Multilevel logistic regression analyses, using a generalized estimating equation approach, were performed.

RESULTS

57% of the wards employed BRNs. In these wards, the BRNs delivered on average 4.8 min of care per resident per day. Among residents living in somatic wards that employed BRNs, the probability of experiencing a fall (odds ratio 1.44; 95% CI 1.06-1.96) and receiving antipsychotic drugs (odds ratio 2.15; 95% CI 1.66-2.78) was higher, whereas the probability of having an indwelling urinary catheter was lower (odds ratio 0.70; 95% CI 0.53-0.91). Among residents living in psychogeriatric wards that employed BRNs, the probability of experiencing a medication incident was lower (odds ratio 0.68; 95% CI 0.49-0.95). For residents from both ward types, the probability of suffering from nosocomial pressure ulcers did not significantly differ for residents in wards employing BRNs.

CONCLUSIONS

In wards that employed BRNs, their mean amount of time spent per resident was low, while quality of care on most wards was acceptable. No consistent evidence was found for a relationship between the presence of BRNs in wards and quality of care outcomes, controlling for background characteristics. Future studies should consider the mediating and moderating role of staffing-related work processes and ward environment characteristics on quality of care.

Supplementing the Braden scale for pressure ulcer risk among medical inpatients: the contribution of self-reported symptoms and standard laboratory tests

AIMS AND OBJECTIVES

To evaluate medical inpatients' symptom experience and selected laboratory blood results as indicators of their pressure ulcer risk as measured by the Braden scale.

BACKGROUND

Pressure ulcers reduce quality of life and increase treatment costs. The prevalence of pressure ulcers is 6-23% in hospital populations, but literature suggests that most pressure ulcers are avoidable.

DESIGN

Prospective, cross-sectional survey.

METHODS

Three hundred and twenty-eight patients admitted to medical wards in an acute hospital in Oslo, Norway consented to participate. Data were collected on 10 days between 2012-2014 by registered nurses and nursing students. Pressure ulcer risk was assessed using the Braden scale, and scores <19 indicated pressure ulcer risk. Skin examinations were categorised as normal or stages I-IV using established definitions. Comorbidities were collected by self-report. Self-reported symptom occurrence and distress were measured with 15 items from the Memorial Symptom Assessment Scale, and pain was assessed using two numeric rating scales. Admission laboratory data were collected from medical records.

RESULTS

Prevalence of pressure ulcers was 11·9, and 20·4% of patients were identified as being at risk for developing pressure ulcers. Multivariable analysis showed that pressure ulcer risk was positively associated with age ≥80 years, vomiting, severe pain at rest, urination problems, shortness of breath and low albumin and was negatively associated with nervousness.

CONCLUSION

Our study indicates that using patient-reported symptoms and standard laboratory results as supplemental indicators of pressure ulcer risk may improve identification of vulnerable patients, but replication of these findings in other study samples is needed.

RELEVANCE TO CLINICAL PRACTICE

Nurses play a key role in preventing pressure ulcers during hospitalisation. A better understanding of the underlying mechanisms may improve the quality of care. Knowledge about symptoms associated with pressure ulcer risk may contribute to a faster clinical judgment of patients at risk.

Nursing documentation of pressure ulcers in nursing homes: comparison of record content and patient examinations

Aim

The aim of this study was to describe the accuracy and quality of nursing documentation of the prevalence, risk factors and prevention of pressure ulcers, and compare retrospective audits of nursing documentation with patient examinations conducted in nursing homes.

Design

This study used a cross‐sectional descriptive design.

Method

A retrospective audit of 155 patients' records and patient examinations using the European Pressure Ulcer Advisory Panel form and the Braden scale, conducted in January and February 2013.

Results

The prevalence of pressure ulcers was 38 (26%) in the audit of the patient records and 33 (22%) in patient examinations. A total of 17 (45%) of the documented pressure ulcers were not graded. When comparing the patient examinations with the patient record contents, the patient records lacked information about pressure ulcers and preventive interventions.

Pressure injury prevention strategies in acute medical inpatients: an observational study

BACKGROUND

Pressure injuries are a patient safety issue. Despite the suite of prevention strategies, sustained reductions in pressure injury prevalence rates have not been achieved. Generally, nurses are usually responsible for assessing patients' pressure injury risk, and then implementing appropriate prevention strategies. The study aim was to describe five planned and implemented pressure injury prevention strategies (risk assessment, management plan, support surface, repositioning, and education), and determine if a relationship existed between the planning and implementation of support surfaces and regular repositioning.

METHOD

An observational study collecting data using chart audits and semi-structured observations. Data were analysed using descriptive and inferential statistics. This study was set in four medical units across two Australian metropolitan hospitals. The sample comprised adult medical inpatients with reduced mobility. A subsample of participants assessed at pressure injury risk on admission was drawn from this sample. Participants were aged ≥18 years, had a hospital length of stay of ≥3 days prior to recruitment, provided an informed consent, and had reduced mobility.

RESULTS

There was suboptimal planning and implementation of pressure injury prevention strategies for the sample and subsample. There was a significant relationship between planned and implemented support surfaces at both hospitals; however, no relationship existed between the planned and implemented of regular repositioning at either site.

CONCLUSION

The planning and implementation of pressure injury strategies is haphazard. Patients received support surfaces; however, gaps exist in pressure injury risk assessment, management planning, regular repositioning, and patient education.

Pressure ulcers in four Indonesian hospitals: prevalence, patient characteristics, ulcer characteristics, prevention and treatment

The objective of this article was to study characteristics of pressure ulcer patients and their ulcers, pressure ulcer preventive and treatment measures in four Indonesian general hospitals. A multicentre cross-sectional design was applied to assess pressure ulcers and pressure ulcer care in adult patients in medical, surgical, specialised and intensive care units. Ninety-one of the 1132 patients had a total of 142 ulcers. Half (44·0%) already had pressure ulcers before admission. The overall prevalence of category I-IV pressure ulcers was 8·0% (95% CI 6·4-9·6), and the overall nosocomial pressure ulcer prevalence was 4·5% (95% CI 3·3-5·7). Most pressure ulcer patients had friction and shear problems, were bedfast, had diabetes and had more bedridden days. Most ulcers (42·3%) were category III and IV. One third of the patients had both pressure ulcers and moisture lesions (36·3%) and suffered from pain (45·1%). The most frequently used prevention measures were repositioning (61·5%), skin moisturising (47·3%), patient education (36·3%) and massage (35·2%). Most pressure ulcer dressings involved saline-impregnated or antimicrobial gauzes. This study shows the complexities of pressure ulcers in Indonesian general hospitals and reveals that the quality of pressure ulcer care (prevention and treatment) could be improved by implementing the recent evidence-based international guideline.

Knowledge and attitudes of health professionals towards pressure ulcers at a rehabilitation hospital: a cross-sectional study

BACKGROUND

Pressure ulcers are common conditions among hospitalized patients and impose substantial burden on patients and their caregivers. To assess the knowledge and attitudes of health professionals towards PUs prevention.

METHODS

A cross-sectional study was performed in the rehabilitation hospital at King Fahad Medical City, Riyadh, Saudi Arabia in 2014. The study population consisted of nurses, physical therapists, occupational therapists, and physical medicine rehabilitation physicians who have a minimum of at least one year of clinical practice. The survey that was created for use in this study consisted of demographic characteristics, Pressure Ulcers Knowledge Test and Staff Attitude Scale.

RESULTS

The survey was completed by 105 participants of the 120 total eligible staff. The mean knowledge score of correct answers from all participants was 34.1 ± 4.8 (71.5 %). Only 77(73.3 %) participants had a mean knowledge score of ≥ 70 %. The mean attitude score was 30.5 (56.5 %). The study revealed that age and profession factors had a significant relationship with participants' mean knowledge of PUs prevention (P < 0.001), (P < 0.001) respectively. Moreover, 101 (98.1 %) participants are concerned about PUs prevention in their practices. While, 11 (10.7 %) of participants believe that PUs prevention is a time consuming procedure.

CONCLUSIONS

The present study assessed the current knowledge and attitudes of health professionals regarding PUs prevention in an acute rehabilitation hospital. The majority of participants had an average level of knowledge and exhibited unsatisfactory attitudes towards PUs prevention. Increased health professionals awareness may improve their attitudes towards PUs prevention.

Prevalence of foot disease and risk factors in general inpatient populations: a systematic review and meta-analysis

OBJECTIVE

To systematically review studies reporting the prevalence in general adult inpatient populations of foot disease disorders (foot wounds, foot infections, collective 'foot disease') and risk factors (peripheral arterial disease (PAD), peripheral neuropathy (PN), foot deformity).

METHODS

A systematic review of studies published between 1980 and 2013 was undertaken using electronic databases (MEDLINE, EMBASE and CINAHL). Keywords and synonyms relating to prevalence, inpatients, foot disease disorders and risk factors were used. Studies reporting foot disease or risk factor prevalence data in general inpatient populations were included. Included study's reference lists and citations were searched and experts consulted to identify additional relevant studies. 2 authors, blinded to each other, assessed the methodological quality of included studies. Applicable data were extracted by 1 author and checked by a second author. Prevalence proportions and SEs were calculated for all included studies. Pooled prevalence estimates were calculated using random-effects models where 3 eligible studies were available.

RESULTS

Of the 4972 studies initially identified, 78 studies reporting 84 different cohorts (total 60 231 517 participants) were included. Foot disease prevalence included: foot wounds 0.01-13.5% (70 cohorts), foot infections 0.05-6.4% (7 cohorts), collective foot disease 0.2-11.9% (12 cohorts). Risk factor prevalence included: PAD 0.01-36.0% (10 cohorts), PN 0.003-2.8% (6 cohorts), foot deformity was not reported. Pooled prevalence estimates were only able to be calculated for pressure ulcer-related foot wounds 4.6% (95% CI 3.7% to 5.4%)), diabetes-related foot wounds 2.4% (1.5% to 3.4%), diabetes-related foot infections 3.4% (0.2% to 6.5%), diabetes-related foot disease 4.7% (0.3% to 9.2%). Heterogeneity was high in all pooled estimates (I(2)=94.2-97.8%, p<0.001).

CONCLUSIONS

This review found high heterogeneity, yet suggests foot disease was present in 1 in every 20 inpatients and a major risk factor in 1 in 3 inpatients. These findings are likely an underestimate and more robust studies are required to provide more precise estimates.

Patient and organisational variables associated with pressure ulcer prevalence in hospital settings: a multilevel analysis

OBJECTIVES

To investigate the association of ward-level differences in the odds of hospital-acquired pressure ulcers (HAPUs) with selected ward organisational variables and patient risk factors.

DESIGN

Multilevel approach to data from 2 cross-sectional studies.

SETTINGS

4 hospitals in Norway were studied.

PARTICIPANTS

1056 patients at 84 somatic wards.

PRIMARY OUTCOME MEASURE

HAPU.

RESULTS

Significant variance in the odds of HAPUs was found across wards. A regression model using only organisational variables left a significant variance in the odds of HAPUs across wards but patient variables eliminated the across-ward variance. In the model including organisational and patient variables, significant ward-level HAPU variables were ward type (rehabilitation vs surgery/internal medicine: OR 0.17 (95% CI 0.04 to 0.66)), use of preventive measures (yes vs no: OR 2.02 (95% CI 1.12 to 3.64)) and ward patient safety culture (OR 0.97 (95% CI 0.96 to 0.99)). Significant patient-level predictors were age >70 vs <70 (OR 2.70 (95% CI 1.54 to 4.74)), Braden scale total score (OR 0.73 (95% CI 0.67 to 0.80)) and overweight (body mass index 25-29.99 kg/m(2)) (OR 0.32 (95% CI 0.17 to 0.62)).

CONCLUSIONS

The fact that the odds of HAPU varied across wards, and that across-ward variance was reduced when the selected ward-level variables entered the explanatory model, indicates that the HAPU problem may be reduced by ward-level organisation of care improvements, that is, by improving the patient safety culture and implementation of preventive measures. Some wards may prevent pressure ulcers better than other wards. The fact that ward-level variation was eliminated when patient-level HAPU variables were included in the model indicates that even wards with the best HAPU prevention will be challenged by an influx of high-risk patients.

Knowledge and practice of nurses towards prevention of pressure ulcer and associated factors in Gondar University Hospital, Northwest Ethiopia

Background

Pressure ulcers are the common conditions among patients hospitalized in acute and chronic care facilities and impose significant burden on patients, their relatives and caregivers. Pressure ulcers have been described as one of the most costly and physically debilitating complications since the 20^th century. The pain and discomfort due to pressure ulcer prolongs illness, rehabilitation, time of discharge and even contribute to disability and death. This study was aimed to assess knowledge, practice and factors associated with pressure ulcer prevention among nurses in Gondar University Hospital, North-west Ethiopia.

Method

An institution-based cross-sectional survey was conducted from March 15 - April 10, 2014 among 248 nurses in Gondar University hospital. A pretested and structured self-administered questionnaire was used for data collection. Data were entered using EPI info version 3.5.3 statistical software and analyzed using SPSS version 20 statistical package. Descriptive statistics was used to describe the study population in relation to relevant variables. Bivariate and multivariate logistic regression was also carried out to see the effect of each independent variable on the dependent variable.

Result

Nearly half (54.4 %) of the nurses had good knowledge; similarly 48.4 % of them had good practice on prevention of pressure ulcer. Educational status [Adjusted Odds Ratio (AOR) = 2.4, 95 % CI (1.39-4.15)], work experience [AOR = 4.8, 95 % CI (1.31-10.62)] and having formal training [AOR = 4.1, 95 % CI (1.29-9.92)] were significantly associated with knowledge on prevention of pressure ulcer. While, satisfaction with nursing leadership [AOR = 1.9, 95 % CI (1.04-3.82)], staff shortage [AOR = 0.07, 95 % CI (0.03-0.13)] and inadequate facilities and equipment [AOR = 0.4, 95 % CI (0.19-0.83)] were found to be significantly associated with the practice on prevention of pressure ulcer.

Conclusion

Knowledge and practice of the nurses regarding prevention of pressure ulcer was found to be inadequate. Having higher educational status, attending formal training and being experienced were positively associated with knowledge; while shortage of facilities and equipments, dissatisfaction with nursing leadership and inadequate staff number showed negative association with practice of nurse’s pressure ulcer prevention. In-service training and upgrading courses are some of the important steps to improve nurses’ knowledge and practice on prevention of ulcer pressure.

Patient perceptions of the role of nutrition for pressure ulcer prevention in hospital: an interpretive study

PURPOSE

The aims of this study were to explore (a) patients' perceptions of the role of nutrition in pressure ulcer prevention; and (b) patients' experiences with dieticians in the hospital setting.

DESIGN

Interpretive qualitative study.

SUBJECTS AND SETTING

The sample comprised 13 females and 7 males. Their mean age was 61.3 ± 12.6 years (mean ± SD), and their average hospital length of stay was 7.4 ± 13.0 days. The research setting was a public health hospital in Australia.

METHODS

In this interpretive study, adult medical patients at risk of pressure ulcers due to restricted mobility participated in a 20 to 30 minute interview using a semi-structured interview guide. Interview questions were grouped into 2 domains; perceptions on the role of nutrition for pressure ulcer prevention; and experiences with dieticians. Recorded interviews were transcribed and analyzed using content analysis.

RESULTS

Within the first domain, 'patient knowledge of nutrition in pressure ulcer prevention,' there were varying patient understandings of the role of nutrition for prevention of pressure ulcers. This is reflected in 5 themes: (1) recognizing the role of diet in pressure ulcer prevention; (2) promoting skin health with good nutrition; (3) understanding the relationship between nutrition and health; (4) lacking insight into the role of nutrition in pressure ulcer prevention; and (5) acknowledging other risk factors for pressure ulcers. Within the second domain, patients described their experiences with and perceptions on dieticians. Two themes emerged, which expressed differing opinions around the role and reputation of dieticians; they were receptive of dietician input; and displaying ambivalence towards dieticians' advice.

CONCLUSIONS

Hospital patients at risk for pressure ulcer development have variable knowledge of the preventive role of nutrition. Patients had differing perceptions of the importance and value of information provided by dieticians.

The prevalence, prevention and multilevel variance of pressure ulcers in Norwegian hospitals: a cross-sectional study

BACKGROUND

Pressure ulcers are preventable adverse events. Organizational differences may influence the quality of prevention across wards and hospitals.

OBJECTIVE

To investigate the prevalence of pressure ulcers, patient-related risk factors, the use of preventive measures and how much of the pressure ulcer variance is at patient, ward and hospital level.

DESIGN

A cross-sectional study.

SETTING

Six of the 11 invited hospitals in South-Eastern Norway agreed to participate.

PARTICIPANTS

Inpatients ≥18 years at 88 somatic hospital wards (N=1209). Patients in paediatric and maternity wards and day surgery patients were excluded.

METHODS

The methodology for pressure ulcer prevalence studies developed by the European Pressure Ulcer Advisory Panel was used, including demographic data, the Braden scale, skin assessment, the location and severity of pressure ulcers and preventive measures. Multilevel analysis was used to investigate variance across hierarchical levels.

RESULTS

The prevalence was 18.2% for pressure ulcer category I-IV, 7.2% when category I was excluded. Among patients at risk of pressure ulcers, 44.3% had pressure redistributing support surfaces in bed and only 22.3% received planned repositioning in bed. Multilevel analysis showed that although the dominant part of the variance in the occurrence of pressure ulcers was at patient level there was also a significant amount of variance at ward level. There was, however, no significant variance at hospital level.

CONCLUSIONS

Pressure ulcer prevalence in this Norwegian sample is similar to comparable European studies. At-risk patients were less likely to receive preventive measures than patients in earlier studies. There was significant variance in the occurrence of pressure ulcers at ward level but not at hospital level, indicating that although interventions for improvement are basically patient related, improvement of procedures and organization at ward level may also be important.

Nurses' attitudes and perceived barriers to pressure ulcer prevention in Jordan

OBJECTIVE

To explore Jordanian nurses' attitudes toward pressure ulcer prevention and to identify their perceived barriers to care in pressure ulcer prevention.

METHOD

A cross-sectional multi-centre study was undertaken in four hospitals in Jordan. The registered nurses and nurse assistants working at these sites were requested to complete a self-administered questionnaire.

RESULTS

In total, 428 completed questionnaires were returned. The participant nurses hold positive attitudes regarding pressure ulcers prevention (mean=3.91). The only factor that seems to have an effect on the positive attitude was the experience of the participants (χ²[2, n=227]=6.38; [=0.041). The positive attitude was enhanced with increased number of years of experience. Several barriers to good practice were reported by the participants, including: lack of staff (86.2%), time (83.6%), and patient conditions (68.6%).

CONCLUSION

Findings of this study suggest that positive attitudes are not enough to change practice. Several barriers need to be resolved first if effective prevention is to be provided. This should form a reference dataset that needs to be addressed in the tissue viability field in Jordan, which is still in its infancy.

A review of PU prevalence and incidence across Scandinavia, Iceland and Ireland (Part I)

OBJECTIVE

To provide a critical appraisal and synthesis of the published literature pertaining to pressure ulcer (PU) prevalence, incidence and prevention practices from the context of Scandinavia, Iceland and Ireland.

METHOD

An integrative research review following Cooper's five stages. Studies published in peer-reviewed journals, involving any study design, but specifically exploring PU prevalence or incidence in adults or children, in any care setting, were included.

RESULTS

Fifty-five papers were data extracted, quality appraised and included in the qualitative synthesis of the review. Mean prevalence in Norway was 17% (4.8-29%) in Ireland was 16% (4-37%), in Denmark was 15% (2.2-35.5%) and in Sweden was 25%, (0.04-42.7%). Prevalence in Iceland was 8.9%. In acute care, mean prevalence was 21% (0-42.7%) and in long stay was 12% (2.4-23.7%). Prevalence among hospice patients was 35.7%, and in community care was 0.04% and 4%. No incidence study from Iceland was identified; the single incidence study from Norway noted a figure of 16.4%. The mean incidence from Ireland was 11% (8-14.4%) from Sweden was 20% (3.1-49%) and Denmark was 1.8% (1.4-2.7%). Mean incidence in acute care setting was 17.6%, (1.4-49%); in long stay was 6.63% (3.1-8.4%). Incidence in the hospice setting was 20.4%. No study reported PU incidence figures from the community setting.

CONCLUSION

Figures for both prevalence and incidence were similar in Ireland and Norway and highest in Sweden, whereas Denmark demonstrated the lowest incidence rates and Iceland demonstrated the lowest prevalence rates. Figures were consistently highest in acute care and hospice settings, and lowest in the care of the older person setting.

The prevalence of pressure ulceration among Jordanian hospitalised patients

OBJECTIVE

To measure the prevalence rate of pressure ulcers (PUs) among hospitalised patients and to assess the adequacy of preventative care provided to patients at-risk for PUs.

METHOD

A cross-sectional survey was conducted by inspecting the skin of each patient included; if a PU was noted, it was classified according to the European Pressure Ulcer Advisory Panel grading system. Risk was assessed using the Braden scale and the use of preventative interventions was also documented.

RESULTS

The sample included was 295 patients; mean age of the patients was 49.1 +/- 18.6 years (range 18-87 years) and 55% (n = 162) were male. The prevalence rate was 16% (8.8% excluding category I). Category I was the most common grade of PU (n = 22; 46%). The heels were the most commonly affected sites (n = 23; 49%). Only 19% of patients in need of prevention actually received proper adequate prevention.

CONCLUSION

PU prevalence rate was lower than published rates in studies that employed the same method. The young age and general health of our sample could be the best explanation. A very small percentage of at-risk patients receive adequate prevention. This should open the door to scrutinising the provision of PU prevention in Jordan.

Knowledge and use of pressure ulcer preventive measures in nursing homes: a comparison of Dutch and German nursing staff

AIMS AND OBJECTIVES

To examine the knowledge and use of pressure ulcer preventive measures among nursing staff in Dutch and German nursing homes.

BACKGROUND

Studies in the Netherlands and Germany have shown a large discrepancy in pressure ulcer prevalence rates among nursing homes in both countries and concluded that some of this variance could be explained by differences in pressure ulcer prevention.

DESIGN

A cross-sectional questionnaire survey nested in a prospective multicenter cohort study.

METHODS

A questionnaire was distributed to nursing staff employed in 10 Dutch nursing homes (n = 600) and 11 German nursing homes (n = 578). Data were collected in January 2009.

RESULTS

The response rate was 75·7% in the Netherlands (n = 454) and 48·4% in Germany (n = 283). Knowledge about useful pressure ulcer preventive measures was moderate in both countries, while nonuseful preventive measures were poorly known. On average, only 19·2% (the Netherlands) and 24·6% (Germany) of preventive measures were judged correctly as nonuseful. The same pattern could be seen with regard to the use of preventive measures, because nonuseful preventive measures were still commonly used according to the respondents.

CONCLUSIONS

The results indicate that the respondents' knowledge and use of pressure ulcer preventive measures could be improved in both countries, especially for nonuseful measures. Changes and improvements can be achieved by providing sufficient education and refresher courses for nurses and nursing assistants employed within Dutch and German nursing homes.

RELEVANCE TO CLINICAL PRACTICE

Recurring education about pressure ulcer prevention is required among nursing staff employed in Dutch and German nursing homes, particularly in relation to the use of ineffective and outdated preventive measures. Obstacles regarding the implementation of preventive measures should be addressed to achieve a change in practice.

The turn team: a novel strategy for reducing pressure ulcers in the surgical intensive care unit

BACKGROUND

Pressure ulcers cause significant morbidity and mortality in the surgical intensive care unit (SICU). The purpose of this study was to determine if a dedicated team tasked with turning and repositioning all hemodynamically stable SICU patients could decrease the formation of pressure ulcers.

STUDY DESIGN

A total of 507 patients in a 20-bed SICU in a university hospital were assessed for pressure ulcers using a point prevalence strategy, between December 2008 and September 2010, before and after implementation of a team tasked with turning and repositioning all hemodynamically stable patients every 2 hours around the clock.

RESULTS

At baseline, when frequent turning was encouraged but not required, a total of 42 pressure ulcers were identified in 278 patients. After implementation of the turn team, a total of 12 pressure ulcers were identified in 229 patients (p < 0.0001). The preintervention group included 34 stage I and II ulcers and 8 higher stage ulcers. After implementation of the turn team, there were 7 stage I and II ulcers and 5 higher stage ulcers. The average Braden score was 16.5 in the preintervention group and 13.4 in the postintervention group (p = 0.04), suggesting that pressure ulcers were occurring in higher risk patients after implementation of the turn team.

CONCLUSIONS

A team dedicated to turning SICU patients every 2 hours dramatically decreased the incidence of pressure ulcers. The majority of stage I and stage II ulcers appear to be preventable with an aggressive intervention aimed at pressure ulcer prevention.

Peri-operative nurses' knowledge and reported practice of pressure injury risk assessment and prevention: A before-after intervention study

BACKGROUND

Patients are at risk of developing pressure injuries in the peri-operative setting. Studies evaluating the impact of educational interventions on peri-operative nurses' knowledge and reported practice are scarce. The purpose of this study was to evaluate the effect of a multifaceted intervention on peri-operative nurses' (a) knowledge of pressure injury risks, risk assessment and prevention strategies for patients in the operating suite; and (b) reported practice relating to risk assessment practices and implementation of prevention strategies for patients in the operating suite.

METHODS

A before-after research design was used. A convenience sample of all registered and enrolled nurses employed in two hospitals' operating suites was recruited. A multifaceted intervention was delivered which comprised a short presentation, educational materials and reminder posters. A 48-item survey tool was completed pre-and post-intervention to measure self-reported knowledge and practice.

RESULTS

70 eligible peri-operative nurses completed both surveys. Post-intervention, statistically significant improvements were seen in knowledge of correct descriptions of pressure injury stages (p=0.001); appropriate reassessment for patients with a new pressure injury (p=0.05); appropriate actions for patients with an existing stage 1 (p=0.02) and stage 2 pressure injury (p=0.04). Statistical improvements were also seen in reported practice relating to an increase in the use of a risk assessment tool in conjunction with clinical judgement (p=0.0008); verbal handover of patients' pressure injury risk status from the operating room nurse to the recovery room (p=0.023) and from the recovery room nurse to the postoperative ward nurse (p=0.045). The number of participants reporting use of non-recommended and recommended pressure-relieving strategies was unchanged.

CONCLUSION

A multi-faceted educational intervention can improve some aspects of perioperative nurses' knowledge and reported practice such as risk assessment practices but not others such as use of recommended pressure-relieving devices. Further research is required to ascertain effective interventions which improve all areas of practice and knowledge, particularly in the use of appropriate pressure-relieving devices in order to prevent pressure injuries in surgical patients.

Potential role of statins on wound healing: review of the literature

Wound healing is a dynamic and complex biological process, which requires coordinated events including haemostasis, inflammation, proliferation, revascularisation and remodelling. Impaired wound healing is a common problem that occurs in both community and hospital settings. Various experimental and clinical studies have evaluated different modalities for the treatment of topical wounds, such as sugar, antibiotics, honey and phytotherapies; also statins have diverse pleiotropic effects that have been suggested to be useful to improve wound healing. Data derived from both animal and human studies showed that statins especially atorvastatin, simvastatin and pravastatin can accelerate the wound-healing process. However, further high-quality and evidence-based studies are needed to address the best statin drug, appropriate dose, the best administration route, duration of treatment and to determine correlation between pleiotropic effects of statins and their probable clinical benefits.
