Presence of pressure ulcer prevention methods used among patients considered at risk versus those considered not at risk

Purpose: This study examined pressure ulcer-prevention strategies available for patients considered at risk versus those considered not at risk.Design: The study used a prospective, longitudinal design.Setting and Subjects: Six hundred ninety-four patients from units of five acute care hospitals, a rehabilitation facility, and two nurses' home care caseloads participated in the investigation.Instruments: Data-collection instruments included the Braden Scale for risk assessment, demographic information, and the Pressure Ulcer-Prevention Strategies tool, which assessed for the presence of 16 pressure ulcer-prevention strategies.Methods: All patients admitted to a participating unit during a 2-month period were followed up until discharge. Depending on the site, patients were assessed for the presence of pressure ulcer-prevention strategies one to three times per week.Results: Patients in the at-risk group versus those in the not-at-risk group were more likely (p < 0.01) to have the head of the bed in a low position, a pressure-reducing bed surface, pressure ulcer prevention charted, a positioning wedge, incontinence cleanser and ointment, heel protection, a prevention care plan, a trapeze, and a posted turning schedule. The at-risk group had significantly (p < 0.01) more prevention strategies present than did the not-at-risk group. However, the percentage of patients placed on a pressure ulcer-prevention program was low for both groups.Conclusions: Pressure ulcer prevention was evident for the at-risk group, but at a low rate. Institutions must continue to explore this critical area affecting patient outcomes.     

Practice versus knowledge when it comes to pressure ulcer prevention

Purpose: This study was completed to determine the current knowledge and documentation patterns of nursing staff in the prevention of pressure ulcers and to identify the prevalence of pressure ulcers.Methods: This pre-post intervention study was carried out in three phases. In phase I, 67 nursing staff members completed a modified version of Bostrom's Patient Skin integrity Survey. A Braden Scale score, the presence of actual skin breakdown, and the presence of nursing documentation were collected for each patient (n = 43). Phase II consisted of a 20-minute educational session to all staff. In phase III, 51 nursing staff completed a second questionnaire similar to that completed in phase I. Patient data (n = 49) were again collected using the same procedure as phase I.Results: Twenty-seven staff members completed questionnaires in both phase I and phase III of the study. No statistically significant differences were found in the knowledge of the staff before or after the educational session. The number of patients with a documented plan of care showed a statistically significant difference from phase I to phase III. The number of patients with pressure ulcers or at risk for pressure ulcer development (determined by a Braden Scale score of 16 or less) did not differ statistically from phase I to phase III.Conclusion: Knowledge about pressure ulcers in this sample of staff nurses was for the most part current and consistent with the recommendations in the Agency for Health Care Policy and Research guideline. Documentation of pressure ulcer prevention and treatment improved after the educational session. Although a significant change was noted in documentation, it is unclear whether it reflected an actual change in practice.     

Independent risk factors for pressure ulcer development in a high‐risk nursing home population receiving evidence‐based pressure ulcer prevention: Results from a study in 26 nursing homes in Belgium

The aim of this study was to identify independent risk factors for pressure ulcer (PU) development in a high‐risk nursing home population receiving evidence‐based PU prevention. This study was part of a randomised controlled trial examining the (cost‐)effectiveness of static air support surfaces compared with alternating pressure air mattresses. The sample consisted of 308 residents at a high risk of PU development (presence of non‐blanchable erythema, Braden score ≤ 12 or Braden subscale “mobility” ≤ 2). PU incidence was monitored for 14 days. Demographic variables; functional, physical, and psychological characteristics; and data on skin assessment were collected. Independent risk factors were identified using multiple logistic regression analysis. The overall PU incidence (category II‐IV) was 8.4% (n = 26), and 1.9% (n = 6) of the residents developed a deep PU (category III‐IV). PUs (category II‐IV) were significantly associated with non‐blanchable erythema, a lower Braden score, and pressure area‐related pain in high‐risk residents even if preventive care was provided. These results highlight the need of a systematic risk assessment, including pain assessment and skin observations, in order to determine and tailor preventive care to the needs of high‐risk individuals.     

The effect of Web-based Braden Scale training on the reliability and precision of Braden Scale pressure ulcer risk assessments.

OBJECTIVE: To evaluate the effect of Web-based Braden Scale training on the reliability and precision of pressure ulcer risk assessments made by registered nurses (RN) working in acute care settings. DESIGN: Pretest-posttest, 2-group, quasi-experimental design. SETTING AND SUBJECTS: Five hundred Braden Scale risk assessments were made on 102 acute care patients deemed to be at various levels of risk for pressure ulceration. Assessments were made by RNs working in acute care hospitals at 3 different medical centers where the Braden Scale was in regular daily use (2 medical centers) or new to the setting (1 medical center). INSTRUMENT: The Braden Scale for Predicting Pressure Sore Risk was used to guide pressure ulcer risk assessments. A Web-based version of the Detroit Medical Center Braden Scale Computerized Training Module was used to teach nurses correct use of the Braden Scale and selection of risk-based pressure ulcer prevention interventions. RESULTS: In the aggregate, RN generated reliable Braden Scale pressure ulcer risk assessments 65% of the time after training. The effect of Web-based Braden Scale training on reliability and precision of assessments varied according to familiarity with the scale. With training, new users of the scale made reliable assessments 84% of the time and significantly improved precision of their assessments. The reliability and precision of Braden Scale risk assessments made by its regular users was unaffected by training. CONCLUSION: Technology-assisted Braden Scale training improved both reliability and precision of risk assessments made by new users of the scale, but had virtually no effect on the reliability or precision of risk assessments made by regular users of the instrument. Further research is needed to determine best approaches for improving reliability and precision of Braden Scale assessments made by its regular users.     

Using the Braden subscales to assess risk of pressure injuries in adult patients: A retrospective case‐control study

The aim of this study was to compare the pressure injury risk predictability between the individual Braden subscales and the total Braden scale in adult inpatients in Singapore. A retrospective 1:1 case‐control design was used from a sample of 199 patient medical records. Clinical data were collected from a local university hospital's medical records database. The results showed that, among the six subscales, the activity subscale was the most sensitive and specific in predicting pressure injury (PI). However, the overall results showed that the Braden scale remained the most predictive of PI development in comparison with the individual subscales. The study also found that, among the Singaporean patients, the Braden cut‐off score for PI risk was 17 compared with the current cut‐off score of 18. Therefore, it may be relevant for local tertiary hospitals to review their respective Braden cut‐off scores as the study results indicate an over‐prediction of PI risk, which leads to unnecessary utilisation of resources. The hospital may also consider developing a PI prevention bundle comprising commonly used preventive interventions when at least one Braden subscale reflects a suboptimal score.     

Peer-to-peer nursing rounds and hospital-acquired pressure ulcer prevalence in a surgical intensive care unit: a quality improvement project

We conducted a quality improvement project in order to evaluate the effect of nurse-to-nurse bedside "rounding" as a strategy to decrease hospital-acquired pressure ulcers (HAPU) in a surgical intensive care unit. We instituted weekly peer-to-peer bedside skin rounds in a 17-bed surgical intensive care unit. Two nurses were identified as skin champions and trained by the hospital's certified WOC nurse to conduct skin rounds. The skin champion nurses conducted weekly peer-to-peer rounds that included discussions about key elements of our patients' skin status including current Braden Scale for Pressure Sore Risk score, and implementation of specific interventions related to subscale risk assessment. If a pressure ulcer was present, the current action plan was reevaluated for effectiveness. Quarterly HAPU prevalence studies were conducted from January 2008 to December 2010. Nineteen patients experienced a HAPU: 17 were located on the coccyx and 2 on the heel. Ten ulcers were classified as stage II, 3 PU were stage IV, 5 were deemed unstageable, and 1 was classified as a deep tissue injury. The frequency of preventive interventions rose during our quality improvement project. Specifically, the use of prevention surfaces increased 92%, repositioning increased 30%, nutrition interventions increased 77%, and moisture management increased 100%. Prior to focused nursing rounds, the highest HAPU prevalence rate was 27%. After implementing focused nursing rounds, HAPU rates trended down and were 0% for 3 consecutive quarters.     

Subscales, subscores, or summative score: evaluating the contribution of Braden Scale items for predicting pressure ulcer risk in older adults receiving home health care.

PURPOSE: The purpose of this study was to determine whether certain Braden subscales or subscores were more important than others or the summative score in predicting stage I to IV pressure ulcers among older adults receiving home health care. DESIGN: A retrospective cohort study (secondary analysis) was used. SETTING AND SUBJECTS: The cohort sample included 1684 nonhospice patients who were not receiving intravenous therapy and who were admitted to the Intermittent Skilled Nursing Division of a large midwestern home health care agency between January 1995 and March 1996. The patients were > or =60 years and free of pressure ulcers. METHODS: Demographic data and data on the Braden Scale were extracted from admission information. Patient records were followed forward chronologically to 1 of 2 outcomes: development or absence of pressure ulcers (ie, free of pressure ulcers upon discharge, institutionalization, death, or the end of the study period). RESULTS: Following admission, a stage I to IV pressure ulcer developed in 107 subjects (incidence = 6.3%). Cox regression analysis revealed that activity and moisture subscale scores predicted pressure ulcer development. Regression modeling of individual Braden Scale subscores (response categories) revealed that problems with friction/shear, being very limited in mobility, and being constantly moist, very moist, or occasionally moist predicted pressure ulcer development. When the overall level of risk was added to each of these models, the Braden Scale summative score was most strongly related to pressure ulcer development. No simplified scale improved risk prediction. CONCLUSIONS: When the Braden Scale was used, the summative score rather than any subscale or subscore best predicted pressure ulcer risk among the older adults receiving home health care.     

Surgical site infections after arthroscopy: Outbreak investigation and case control study

Purpose: The goal of this study was to determine the causes of increased post-arthroscopy surgical site infections (SSIs) and to define risk factors for infection. Type of Study: Outbreak investigation and case control study at a university-affiliated community hospital from 1994 to 1996, with surveillance through 1999. Methods: Demographic, clinical, and microbiological data were collected on 27 post-arthrocopy SSIs from 1994 through 1999. Risk factors for SSI were identified by case-control analysis and presented as odds ratios (OR) and 95% confidence intervals (CI). Results: Initial investigation revealed an increased annual rate of post-arthroscopy SSIs in 1995 (1.3%). Infection control deficiencies were identified, and feedback was provided to surgeons and staff. Instrument sterilization was standardized, flash sterilization prohibited, and preoperative shaving discouraged. Case-control analysis of 10 cases (from 1994 to 1996) found a statistically significant increase in risk of SSI with intra-articular corticosteroid joint injection (OR, 9.33; 95% CI, 1.6 to 64.9); other risk factors did not reach statistical significance. SSI rates dropped after feedback and education (0.34% in 1996). Continued surveillance revealed 2 smaller outbreaks, in December 1997 (1997 rate, 1.13%) and September 1998 (1998 rate, 1.09%). Case-control analysis of the 17 cases occurring in 1997 through 1999 was also performed. The 1997 outbreak appeared to be related to preoperative razor shaving (P = .003), which was then prohibited by hospital policy. One scrub nurse was also associated with 75% of these cases, which were culture-positive for coagulase-negative Staphylococcus. The cases in the 1998 outbreak shared prolonged procedure duration and conversion to arthrotomy. Of 27 cases, 24 required repeat hospitalization and repeat surgery, at an average excess cost of $9,154.84 per case. All received prolonged courses of intravenous or oral antibiotics. Conclusions: Post-arthroscopy SSIs are associated with significant morbidity and cost. Although small numbers make finding statistical significance difficult in case-control studies, infection control and CDC-recommended interventions can lower SSI rates. Careful definitions, ongoing surveillance, and long-term follow-up are helpful in reporting results of infection control interventions.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 19, No 2 (February), 2003: pp 172–181     

Evaluation of a protocol for prevention of facility-acquired heel pressure ulcers.

OBJECTIVE: We sought to determine whether identification of comorbidities (in addition to daily Braden scale assessment and early aggressive pressure reduction interventions) would impact the development of facility-acquired pressure ulcers (FAPU) of the heel. METHODS: Patients admitted to a 333-bed community hospital located 20 miles west of Chicago. Overall, 70 medical records were reviewed, while 242 adult patients (46 in the intervention groups and 196 in the control groups) and 24 nurses participated in the study. The study was conducted in 4 phases, including a retrospective chart audit, 2 prospective interventions, and a product evaluation. Phase 1 entailed a retrospective chart review of patients who were admitted with or developed heel pressure ulcers over a 2-year period to identify factors most predictive of skin breakdowns. Phase 2 included two 10-day aggressive assessment and tailored intervention periods. Phase 3 involved prevalence day assessments of effectiveness of interventions as compared to patients on control nursing units. Phase 4 involved a staff survey comparing effectiveness and satisfaction of the current and trial heel pressure-relieving products. FINDINGS: Risk factors for development of heel ulcers during hospital stay or prior to admission included type 2 diabetes mellitus (T2DM), peripheral vascular disease (PVD), low albumin, and Braden scale score. During implementation of phase 2 (two 10-day assessment and tailored intervention periods), no heel FAPU were associated with the intervention. During the phase 3 FAPU prevalence assessment, 3 patients had facility-acquired heel ulcers; 2 were in the control group and would have met inclusion criteria if included in the intervention. One patient was in the intervention group but was not following the protocol. During phase 4, there were significant preferences for the trial heel pressure relief device on effectiveness, as well as patient and staff satisfaction. CONCLUSION: A pressure ulcer prevention protocol that incorporated accurate assessment of risk factors (Braden Scale and comorbidities) with frequent documentation of heel skin integrity had a positive impact on the incidence of heel FAPU. In addition, early aggressive implementation of pressure-reducing and pressure-relieving devices was effective in reducing FAPU rates.     

Relationship between Braden scale score and pressure ulcer development in patients admitted in trauma intensive care unit

The purpose of this study was to determine the relationship between the scores of Braden scale and pressure ulcer development among critically ill patients. All patients who admitted to intensive care unit (ICU) in 3 months (during July-October 2010) were surveyed with Braden scale. Patients who gained higher score of Braden scale were at lower risk for pressure ulcer development compared with the other patients. Braden scale is a useful tool for predicting pressure ulcer development in trauma ICU patients. Also, factors such as age and level of consciousness may influence pressure ulcer development.     

Cost-identification analysis of revascularization procedures on patients with peripheral arterial occlusive disease

Objective: To determine average total in-hospital costs of various revascularization procedures for peripheral arterial occlusive disease; to examine the effect of procedure-related complications and patient characteristics on these costs; and to examine whether costs have changed over time. Methods: We collected cost data on all admissions involving one revascularization procedure for peripheral arterial occlusive disease at the Brigham and Women's hospital from 1990 through 1995 (n = 583). The main outcome measures were total costs per admission in 1995 US dollars and length of stay in days. Results: For each of 12 different procedures identified, total costs per admission varied considerably. Multiple linear regression analysis was performed to determine the effect of local and systemic complications and of patient characteristics on total in-hospital costs per admission. The additional cost incurred for fatal systemic complications was $11,675 (P = .004) and for nonfatal systemic complications was $9345 (P < .001). The results demonstrated significant additional costs with management of critical ischemia versus intermittent claudication ($4478, P < .001), presence of coronary artery disease ($1287, P = .05), female sex ($1461, P = .03), and advanced age ($1345, P = .02). No statistically significant changes over time were demonstrated. Conclusion: Total in-hospital costs per admission for peripheral revascularization procedures are highly variable and significantly increased by procedure-related complications, advanced age, female sex, management of critical ischemia, and presence of coronary artery disease.

A prediction tool for hospital‐acquired pressure ulcers among surgical patients: Surgical pressure ulcer risk score

Surgical patients are prone to developing hospital‐acquired pressure ulcers (HAPU). Therefore, a better prediction tool is needed to predict risk using preoperative data. This study aimed to determine, from previously published HAPU risk factors, which factors are significant among our surgical population and to develop a prediction tool that identifies pressure ulcer risk before the operation. A literature review was first performed to elicit all the published HAPU risk factors before conducting a retrospective case‐control study using medical records. The known HAPU risks were compared between patients with HAPU and without HAPU who underwent operations during the same period (July 2015‐December 2016). A total of 80 HAPU cases and 189 controls were analysed. Multivariate logistic regression analyses identified eight significant risk factors: age ≥ 75 years, female gender, American Society of Anaesthesiologists ≥ 3, body mass index < 23, preoperative Braden score ≤ 14, anaemia, respiratory disease, and hypertension. The model had bootstrap‐corrected c‐statistic 0.78 indicating good discrimination. A cut‐off score of ≥6 is strongly predictive, with a positive predictive value of 73.2% (confidence interval [CI]: 59.7%‐84.2%) and a negative predictive value of 80.7% (CI: 74.3%‐86.1%). SPURS contributes to the preoperative identification of pressure ulcer risk that could help nurses implement preventive measures earlier.     

Characteristics of hospitalised US veterans with nosocomial pressure ulcers

The objective of this study was to describe demographic and clinical characteristics of hospitalised US veterans with nosocomial pressure ulcer (NPU) referred to a certified Wound, Ostomy & Continence Nurse (WOCN). We conducted a retrospective review of electronic records at a Veterans Affairs Medical Center in the northwestern USA. Records of veterans with NPU referred to a WOCN (n = 29) from May 2005 to June 2006 were reviewed. Location and stage of pressure ulcer(s), Braden score on admission and when the ulcer was first noted, day of hospital stay when the ulcer was first noted, medical diagnoses and clinical conditions and events such as surgery, hypoxemia, hypoalbuminemia and hypotension were recorded. Mean age of the patients was 69·8. The most common location was the sacrum/coccyx. Most ulcers were stage 1 when identified. Braden score during admission classified half of the sample at risk, but 81% of Braden scores at ulcer occurrence were <18. Ninety percent of the sample had three or more comorbidities. Over half had died in the 1–14 months after the reviewed hospitalisation. Hospitalised veterans referred for WOCN consultation had multiple risk factors and comorbid conditions, including hypoxemia, serum albumin depletion, anaemia and hypotension. Veterans cared for in Veterans Affairs Medical Centers are known to have multiple health problems, and those in this sample not only had nosocomial pressure ulcer, but also other physiological derangements that may shorten survival.     

Effects of a pressure-reduction mattress and staff education on the incidence of nosocomial pressure ulcers

Purpose: The purpose of this study was to determine whether replacing standard hospital mattresses with pressure-reduction mattresses and educating the patient care team on Agency for Health Care Policy and Research prevention guidelines would decrease the incidence of nosocomial pressure ulcers.Design: Retrospective chart review before and after implementation of replacement of standard hospital mattresses with pressure-reduction mattresses and before and after patient care team education was completed.Setting and Subjects: A 6-month clinical study with 141 subjects was conducted on a skilled-nursing unit.Methods: The 3-month preintervention sample group of 141 subjects received routine nursing care on a standard hospital mattress. After the introduction of pressure-reduction mattresses and an education program, a 3-month postintervention sample group of 141 subjects was studied.Main Outcome Measures: Incidence of nosocomial pressure ulcers during a 3-month period.Results: Among the preintervention group, 21 of 141 subjects (15%) acquired nosocomial pressure ulcers, versus 16 of 141 subjects (11%) in the postintervention group. This improvement was not statistically significant (χ² = 0.78, df = 1, p = 0.38). The incidence of ulcers staged II or higher dropped from 11 patients in the preintervention group to six in the postintervention group, a 45% reduction that was not statistically significant (χ² = 1.56, df = 1, p = 0.21).Conclusion: Replacement of standard hospital mattresses and education of staff according to recommendations from the Agency for Health Care Policy and Research guideline for pressure ulcer prediction and prevention did not significantly change the incidence of pressure ulcers during a 3-month period in our skilled-nursing unit.
