Prevalence and incidence density of unavoidable pressure ulcers in elderly patients admitted to medical units

Comparison of the Predictive Validity of Norton and Braden Scales in Determining the Risk of Pressure Injury in Elderly Patients

AIM

To compare the reliability and predictive validity of Norton and Braden scales in determining the risk of pressure injury in elderly patients.

DESIGN

This research used a comparative design. One hundred thirty elderly patients participated in the study.

METHODS

The daily pressure injury risk of participants was evaluated by a researcher using both the Norton and Braden scales in a consecutive manner.

RESULTS

The mean age of patients was 75.1 ± 8.5 years, and that for those without and with pressure injury development was 75.0 ± 8.3 years and 76.1 ± 9.7 years (P < .001), respectively. The reliability coefficients of the Norton and Braden scales were .82 and .89, respectively. The sensitivity, specificity, and positive and negative predictive values of the Norton Scale were 100%, 40.7%, 20.2%, and 100%, and those of the Braden Scale were 100%, 32.7%, 18.3%, and 100%, respectively.

CONCLUSIONS

The reliability of both scales for elderly patients was found to be high, and their ability to differentiate patients at risk was comparable. However, both scales had low specificity. Further research is needed to develop scales that have higher predictive validity for the elderly population, taking into account other risk factors that influence total scale scores.

The Grading of Recommendations, assessment, development, and evaluation approach was rarely followed and inconsistently applied in pressure injury prevention guidelines development: A cross-sectional survey

INTRODUCTION

The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was developed to assess the certainty (or quality) of evidence and strength of recommendations in guidelines and endorsed internationally as a standard. Some guidelines had been developed to promote pressure injury prevention.

AIMS

We explored whether and to what extent the development of pressure injury prevention guidelines had followed or been informed by the GRADE approach. If this approach was not used, we examined which other methods were used instead.

METHODS

A cross-sectional study of pressure injury prevention guidelines was conducted. PubMed, Embase, CINAHL, and Chinese databases as well as guideline repositories and websites of professional bodies were searched for guidelines from 1990 to 2020. The grading systems of the certainty (or quality) of evidence and strength of recommendations of included guidelines were extracted. For the GRADE approach guidelines, compliance was assessed with the GRADE application criteria.

RESULTS

Twenty guidelines were identified. Among them, four guidelines (20%) indicated the use of the GRADE approach. The compliance rate ranged from 33.3%-94.4%. Other approaches, such as the Scottish Intercollegiate Guidelines Network (SIGN) approach, were also used.

CONCLUSION

The GRADE approach is rarely followed and inconsistently applied in pressure injury prevention guidelines. Other systems, such as the SIGN approach, are being used despite being outdated or inconsistent. Strategies for further uptake and appropriate application of the GRADE approach among guideline developers are needed in the future.

Frequency of and risk factors for intensive care unit-acquired sacrum pressure injuries in critically ill patients: A multicenter cross-sectional study in China

RATIONALE AIMS AND OBJECTIVES

Hospital-acquired pressure injuries (HAPI) prolong hospital stays and are an important health problem worldwide. The aim of this study was to assess the frequency of and risk factors for intensive care unit (ICU)-acquired pressure injuries (IAPI) on the sacrum in critically ill patients in China.

METHODS

We performed a multicenter, cross-sectional survey of IAPI on the sacrum in 23 adult ICUs in 19 hospitals in China. Data for 421 critically ill patients were collected on December 13, 2019, and January 13, 2020, including patient characteristics, physiological, and clinical information. Logistic regression was used to analyze the risk factors for IAPI on the sacrum in the ICU.

RESULTS

Forty-one patients presented sacrum pressure injuries in the ICU, with a frequency of 9.74%. Risk factors that significantly increased the risk of IAPI on the sacrum were lower body mass index (BMI, odds ratio [OR] = 1.115, confidence interval [CI]: 1.011-1.229, P = .029), chronic obstructive pulmonary disease (COPD, OR = 3.183, CI: 1.261-8.037, P = .014), multiple organ dysfunction syndrome (MODS, OR = 2.670, CI: 1.031-6.903, P = .043), and a lower Braden risk score (OR = 1.409, CI: 1.197-1.659, P < .001).

CONCLUSION

Lower BMI, COPD, MODS, and lower Braden risk score are independent risk factors for sacrum IAPI in China.

Consistent practices in pressure ulcer prevention based on international care guidelines: A cross-sectional study

The use of consistent and evidence‐based practices is essential in terms of patient safety and quality of care. The purpose of this study was to describe the use of consistent practices in PU prevention based on international care guidelines and to assess the validity and reliability of the pressure ulcer prevention practice (PUPreP) instrument. The data (n = 554) were collected between 2018 and 2019 from nursing professionals working at two hospital districts in Finland using the PUPreP instrument. The instrument consisted of 42 items assessing participants' perceptions of the frequencies of pressure ulcer prevention practices with the following scale: never, sometimes, often, always. The data were analysed using statistical analysis. According to the results, the use of pressure ulcer prevention practices was more frequently described as often. The most frequently used prevention practice was repositioning, and the least frequently used practice was nutrition. Factors related to nursing professionals' pressure ulcer prevention practices were the working sector, education and working frequency in pressure ulcer prevention, and early identification of pressure ulcers. The study results suggest that the evidence‐based pressure ulcer prevention practices were followed at a moderate level by nurses. The PuPreP instrument demonstrated validity and reliability, but further development is needed.

Effect of interface pressure and skin surface temperature on pressure injury incidence: a turning schedule pilot study

OBJECTIVE

This study aimed to evaluate the interface pressure and skin surface temperature in relation to the incidence of pressure injury (PI) using three different turning schedules.

METHOD

This was a pilot study with a three-armed randomised clinical trial design. Participants at risk of PI and treated in the high dependency care unit in a regional hospital in Makassar, Indonesia participated in this study. Patients were repositioned at three different turning schedules (two-, three- and four-hourly intervals). Interface pressure measurement and skin surface temperature were measured between 14:00 and 18:00 every three days. The incidence of PI was assessed during the two-week observation period.

RESULTS

A total of 44 participants took part in the study. A one-way ANOVA test revealed no difference in interface pressure among the three different turning schedule groups within two weeks of observations: day zero, p=0.56; day four, p=0.95; day seven, p=0.56; day 10, p=0.63; and day 14, p=0.92. Although the average periumbilical temperature and skin surface temperature were not significant (p>0.05), comparison between these observation sites was significant on all observation days (p<0.05). Regarding the incidence of PI, the proportional hazard test for the development of PI in the three groups was considered not different (hazard ratio: 1.46, 95% confidence interval: 0.43-4.87, p=0.54).

CONCLUSION

No difference in interface pressure and incidence of PI on the three turning schedules was observed; however, there was a potential increase in skin surface temperature in comparison with periumbilical temperature for all three turning schedules.

Prevalence and characteristics of older people with pressure ulcers and legs ulcers, in nursing homes in Barcelona

BACKGROUND

Nursing home residents are vulnerable to chronic wounds. However, the prevalence data are scarce.

AIM

The purpose of this study was to determine the prevalence of pressure ulcers and/or leg ulcers in nursing home residents, and describe the characteristics of the nursing homes, the residents and the wounds, as well as possible associations between these characteristics.

METHODS

This was a cross-sectional survey of nursing home residents over the age of 65 in 168 facilities in Barcelona. Those presenting category II-IV pressure ulcers and/or leg ulcers were included. The data were collected by observation/examination. Descriptive, bivariate, and multivariate analyses were performed.

RESULTS

The overall prevalence of pressure ulcers and leg ulcers combined was 4.4% (3.5% were pressure ulcers and 0.9% were leg ulcers). In small nursing homes with less nursing staff, the overall prevalence was greater than in large nursing homes (5.6% vs 3.8% [p = 0.01]). As expected, residents with pressure ulcers had higher pressure ulcer risk, worse dependence and cognitive status, urinary and faecal incontinence, and most were underweight. However, residents with leg ulcers had worse venous and arterial impairment and also were overweight. A multivariate analysis showed that pressure ulcers were statistically significantly associated with faecal incontinence (OR = 0.28, 95% CI = 0.09-0.81) and dyslipidaemia (OR = 0.21, 95% CI = 0.06-0.66), and leg ulcers were statistically significantly associated with venous insufficiency (OR = 4.93, 95% CI = 1.65-15.34). The characteristics of gluteal and ischial pressure ulcers, a high prevalence of infection, and a low reference to biofilm by nurses, in both types of wounds, suggest that these aspects are not adequately taken into account.

CONCLUSIONS

Pressure ulcers and leg ulcers, mainly pressure ulcers, remain a public health problem in nursing homes. Further studies are required to confirm the associations found in this study.

Prevalence, incidence and associated factors of pressure injuries in hospices: A multicentre prospective longitudinal study

BACKGROUND

Patients in palliative care are the population cohort that most frequently develop pressure injuries, severely impacting their quality of life. Data from prospective studies on the prevalence and incidence of pressure injuries in hospices are lacking.

AIM

To describe the point prevalence and cumulative incidence of pressure injuries in patients admitted to residential hospices, and to analyze their predictive factors over time.

DESIGN

Multicentre prospective longitudinal observational study.

SETTING/PARTICIPANTS

Adult patients (n = 992) enrolled in 13 Italian residential hospices, with a minimum sample of 280 for each macro-region (North, center, South/Islands).

METHODS

Assessments including the Karnofsky Performance Status, Braden, Edmonton Symptom Assessment System Revised scales and pressure injury staging according to National Pressure Ulcer Advisory Panel were conducted at least every four days, from admission to patients' death/discharge.

RESULTS

The 7,967 observations recorded provided prevalence and incidence rates of 34.1% and 26.5%, respectively. The logistic regression model showed non-cancer disease (OR = 2.39, 95%CI = 1.65-3.47), age >80 (OR = 2.01, 95%CI = 1.49-2.71), Braden score 'at risk' (OR = 1.92, 95%CI = 1.17-3.14), urinary catheter (OR = 1.96, 95%CI = 1.40-2.75), drowsiness (OR = 1.41, 95%CI = 1.02-1.95) and artificial nutrition (OR = 1.47, 95%CI = 1.01-2.14) as the variables associated with pressure injury at admission. The generalized estimating equations models, built on the timeframes for observation groups, revealed male gender (OR = 1.68, 95%CI = 1.01-2.79) and Braden score 'at risk' (OR = 4.45, 95%CI = 1.74-11.34) as predictive factors of a new pressure injury developed up to three weeks before a patient's death, while in the last ten days of life these predictors were replaced by diagnosis of cancer (OR = 1.80, 95%CI = 1.11-2.91), worsening pain (OR = 1.65, 95%CI = 1.10-2.49), drowsiness (OR = 1.79, 95%CI = 1.25-2.57) and dyspnea (OR = 1.48, 95%CI = 1.01-2.18).

CONCLUSIONS

The high incidence and prevalence of pressure injuries confirm the importance of palliative care nurses continuously focusing on prevention and management strategies. In the last three weeks of a patient's life, the predictive power of the Braden scale for a new pressure injury is not confirmed, throwing doubt on the effectiveness of aimed interventions at modifying risk factors. Along the different disease trajectories, pressure injuries developed during the instability/worsening phases of illness, occurring before hospice admission for non-cancer patients and in the end-of-life phase for cancer patients. Despite continuous provision of appropriate interventions, most of the new pressure injuries were detected during the last ten days of a patient's' life and assessed as 'unavoidable'. These results are crucial to guiding palliative care nursing plans during the different phases of illness, and to predicting care needs, possible management strategies ('wound management' vs. 'wound palliation'), and resource utilization.

The Incidence of Pressure Ulcers and its Associations in Different Wards of the Hospital: A Systematic Review and Meta-Analysis

Pressure ulcer is a health problem worldwide that is common among inpatients and elderly people with physical-motor limitations. To deliver nursing care and prevent the development of pressure ulcers, it is essential to identify the factors that affect it. This global systematic review and meta-analysis was conducted with the aim of evaluating the incidence of pressure ulcers in observational studies. In this study, databases including Web of Science, Embase, PubMed, Scopus, and Google Scholar were searched to collect data. Articles published from 1997 to 2017 about the factors influencing the incidence of pressure ulcers were retrieved and their results were analyzed using meta-analysis according to the Random-Effects Model. The heterogeneity of studies was investigated using the I2 statistic. Data were analyzed using the R and Stata software (version 14). In this study, 35 studies were included in the final analysis. The results showed that the pooled estimate of the incidence rate of pressure ulcer was 12% (95% CI: 10-14). The incidence rates of the pressure ulcers of the first, second, third, and fourth stages were 45% (95% CI: 34-56), 45% (95% CI: 34-56), 4% (95% CI: 3-5), and 4% (95% CI: 2-6), respectively. The highest incidence of pressure ulcers was observed among inpatients in orthopedic surgery ward (18.5%) (95% CI: 11.5-25). According to the final results, better conditions should be provided to decrease the incidence of pressure ulcers in different wards, especially orthopedics, and in patients with diabetes.

Avoidable and Unavoidable Pressure Injuries Among Residents Living in Nursing Homes: A Retrospective Study

PURPOSE

The aim of this study was to describe the prevalence of unavoidable pressure injuries (UPIs) in residents of nursing homes (NHs) and characteristics associated with UPIs.

DESIGN

A retrospective study.

SUBJECTS AND SETTING

Residents 65 years or older residing in any of 105 NHs in the Friuli Venezia Giulia region of Italy between January and December 2013.

METHODS

Database search comprised of a multidimensional assessment of NH residents.

RESULTS

Data from 7950 residents were reviewed, 925 (11.6%) of whom had 1 or more documented pressure injuries (PIs). Among these, 221 (23.9%) residents met criteria for avoidable PIs (APIs) and 704 (76.1%) for UPIs. Residents with UPIs were more frequently hemodynamically unstable, terminally ill, and had medical devices (all Ps < .001) than residents with APIs. Moreover, residents with UPIs showed higher functional, cognitive, and mood impairments compared to residents with APIs (all Ps < .001).

CONCLUSIONS

Our findings suggest a high prevalence of UPIs compared to APIs among residents residing in NHs in one region of Italy. Additional research is needed to establish the prevalence of UPIs among NH residents country-wide, as well as determine specific criteria that identify UPIs in long-term care settings and increase consistency in prevalence and incidence measurement models.

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 hospitalised patients: a cross-sectional study

OBJECTIVE

The main aim of this study was to estimate the prevalence of pressure ulcers (PU) and related risk factors of PU development in hospitalised patients in Italy. Furthermore, the study investigated the association between risk factors for PU present on admission and the development during hospitalisation (hospital-acquired pressure ulcer, HAPU).

METHODS

A cross-sectional study, using two separate designs at two separate timepoints: 2010 and 2015. The methodology used to measure PU prevalence was that recommended by the European Pressure Ulcer Advisory Panel (EPUAP).

RESULTS

The total sample was 7681 hospitalised patients (3011 patients in 2010, 4670 in 2015). Prevalence of PU in hospital was 19.5% in 2010 and 17% in 2015. The number of patients with PU present on admission were 9.60% in 2010 and 9.42% in 2015. Patients with HAPU were 5.08% in 2010 and 5.87% in 2015. Older age and comorbidities, and a total Braden score of ≤16 were positively associated with PU present on admission and HAPU in hospitals (p<0.05). A longer length of stay appeared to correlate positively with a better clinical outcome for PU if there were already present on admission. Heterogeneous results emerged for length of stay of >30 days and being admitted to intensive care unit (ICU).

CONCLUSION

Our results are comparable with other European and Italian studies. Most of the risk factors associated with PU development have been confirmed. However, further studies are needed to examine the effects of context on PU present on arrival and HAPU, especially regarding hospital length of stay.

Relationship between pressure ulcer risk based on Norton Scale and on the "Eating/Drinking" need assessment

AIM

To study the relationship between pressure ulcer risk evaluated by the Norton Scale and inadequate fulfilment of Need 2 (Eating/Drinking) from the 14-need classification designed by Virginia Henderson.

BACKGROUND

Assessing nutritional status and skin condition to implement preventive measures are important nursing interventions. Our hospital's standard procedure requires recording Norton Scale and Henderson Eating/Drinking Assessment results.

METHODS

This was a descriptive cross-sectional study, analysing case histories of 219 patients in medical/surgical wards for >24 hr with nursing care recorded in the GACELA Care computer application. Patient sociodemographic variables and evaluation concepts from the Norton Scale and Eating/Drinking were studied.

RESULTS

A statistically significant relationship (p < 0.05; 95% CI: 0.61, 2.83) was seen between inadequate Eating/Drinking need fulfilment and increased pressure ulcer risk. Pressure ulcer risk was generally low in the sample, with mainly no or minimum risk (77.3%); the oldest age group had the highest risk. Self-care autonomy was the most frequently assessed item in Eating/Drinking (42%).

CONCLUSIONS

A relationship was found between Norton Scale risk results and Eating/Drinking need assessment results. The greater the pressure ulcer risk, the more likely was inadequate need satisfaction (poor nutritional status).

IMPLICATIONS

To help identify pressure ulcer risk, nurses should assess patients' eating independence. Safeguarding nutritional status and preventing pressure ulcers are nursing skills associated with quality nursing care.
