Pressure ulcers in the chronically critically ill patient

Effect of intraoperative pressure ulcer preventive nursing on inflammatory markers in patients with high-risk pressure ulcers: A protocol of systematic review and meta-analysis

BACKGROUND

This study will be designed to appraise the effects of intraoperative pressure ulcer preventive nursing (IPUPN) on inflammatory markers (IMs) in patients with high-risk pressure ulcers (HRPU) based on high quality randomized controlled trials (RCTs).

METHODS

In this study, we will perform a rigorous literature search from the following electronic databases: Cochrane Library, MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, and Chinese Biomedical Literature Database. All electronic databases will be retrieved from their initial time to March 1, 2020 without limitations of language and publication status. We will only consider high quality RCTs that explored the effects of IPUPN on IMs in patients with HRPU. Two investigators will identify relevant trials, extract data, and appraise risk of bias in each eligible trial. Data will be pooled by either a fixed-effects model or a random-effects model according to the results of heterogeneity identification. The primary outcomes include IMs, and incidence of new pressure ulcers. The secondary outcomes are time to ulcer development, quality of life, length of hospital stay, and adverse events. Statistical analysis will be undertaken using RevMan 5.3 software.

RESULTS

This study will summarize high quality clinical evidence of RCTs to evaluate the effects of IPUPN on IMs in patients with HRPU.

CONCLUSION

The expected findings may provide helpful evidence to determine whether IPUPN is an effective intervention on IMs in patients with HRPU.

Chronic critical illness: are we saving patients or creating victims?

The technological advancements that allow support for organ dysfunction have led to an increase in survival rates for the most critically ill patients. Some of these patients survive the initial acute critical condition but continue to suffer from organ dysfunction and remain in an inflammatory state for long periods of time. This group of critically ill patients has been described since the 1980s and has had different diagnostic criteria over the years. These patients are known to have lengthy hospital stays, undergo significant alterations in muscle and bone metabolism, show immunodeficiency, consume substantial health resources, have reduced functional and cognitive capacity after discharge, create a sizable workload for caregivers, and present high long-term mortality rates. The aim of this review is to report on the most current evidence in terms of the definition, pathophysiology, clinical manifestations, treatment, and prognosis of persistent critical illness.

Decubitus ulcers in patients undergoing vascular operations do not influence mortality but affect resource utilization

BACKGROUND

While it is anticipated that decubitus ulcers are detrimental to outcomes after vascular operations, the contemporary influence of perioperative decubitus ulcers in vascular surgery remains unknown.

METHODS

Using the National Impatient Survey, all adult patients who underwent vascular operation were selected. Patients were stratified by the presence or absence (non-decubitus ulcers) of decubitus ulcer. Case-mix adjusted hierarchical mixed-models examined in-hospital mortality, the occurrence of any complication, and discharge disposition.

RESULTS

A total of 538,808 cases were analyzed. Decubitus ulcers were most prevalent among Caucasian male Medicare beneficiaries (P < .001). Decubitus ulcer patients also underwent more nonelective vascular operations (P < .001). Wound, infectious, and procedural complications were more common in patients with decubitus ulcers (P < .001). Failure to rescue, defined as mortality after any complication, was more than doubled in decubitus ulcers (non-decubitus ulcers: 1.5%, decubitus ulcers: 3.2%, P < .001). Similarly, unadjusted mortality was also doubled in patients undergoing vascular operation with decubitus ulcers (non-decubitus ulcers: 3%, decubitus ulcers: 6%, P < .001). After risk adjustment among all patients, neither the presence of a decubitus ulcer nor specific ulcer staging increased the adjusted odds of death. Having a decubitus ulcer increased the adjusted odds of discharge to an intermediate care facility (odds ratio 2.9, P < .001). These patients also had 1.6 times the total charges compared to their non-decubitus ulcer cohort (non-decubitus ulcers: $49,460 ± $281 vs decubitus ulcers: $81,149 ± $5,855, P < .001).

CONCLUSION

Contrary to common perception, perioperative decubitus ulcer does not adversely affect mortality after vascular operation in patients proceeding to operative intervention. Patients with decubitus ulcers are, however, at higher risk for complications and incur sizeable additional charges.

The effect of nitric oxide releasing cream on healing pressure ulcers

BACKGROUND

Pressure ulcer is one of the main concerns of nurses in medical centers around the world, which, if untreated, causes irreparable problems for patients. In recent years, nitric oxide (NO) has been proposed as an effective method for wound healing. This study was conducted to determine the effect of nitric oxide on pressure ulcer healing.

MATERIALS AND METHODS

In this clinical trial, 58 patients with pressure ulcer at hospitals affiliated to Ahvaz Jundishapur University of Medical Sciences were homogenized and later divided randomly into two groups of treatment (nitric oxide cream; n = 29) and control (placebo cream; n = 29). In this research, the data collection tool was the Pressure Ulcer Scale for Healing (PUSH). At the outset of the study (before using the cream), the patients' ulcers were examined weekly in terms of size, amount of exudates, and tissue type using the PUSH tool for 3 weeks. By integrating these three factors, wound healing was determined. Data were analyzed using SPSS.

RESULTS

Although no significant difference was found in terms of the mean of score size, the amount of exudates, and the tissue type between the two groups, the mean of total score (healing) between the two groups was statistically significant (P = 0.04).

CONCLUSIONS

Nitric oxide cream seems to accelerate wound healing. Therefore, considering its easy availability and cost-effectiveness, it can be used for treating pressure ulcers in the future.

The reality of patients requiring prolonged mechanical ventilation: a multicenter study

OBJECTIVE

The number of patients who require prolonged mechanical ventilation increased during the last decade, which generated a large population of chronically ill patients. This study established the incidence of prolonged mechanical ventilation in four intensive care units and reported different characteristics, hospital outcomes, and the impact of costs and services of prolonged mechanical ventilation patients (mechanical ventilation dependency ≥ 21 days) compared with non-prolonged mechanical ventilation patients (mechanical ventilation dependency < 21 days).

METHODS

This study was a multicenter cohort study of all patients who were admitted to four intensive care units. The main outcome measures were length of stay in the intensive care unit, hospital, complications during intensive care unit stay, and intensive care unit and hospital mortality.

RESULTS

There were 5,287 admissions to the intensive care units during study period. Some of these patients (41.5%) needed ventilatory support (n = 2,197), and 218 of the patients met criteria for prolonged mechanical ventilation (9.9%). Some complications developed during intensive care unit stay, such as muscle weakness, pressure ulcers, bacterial nosocomial sepsis, candidemia, pulmonary embolism, and hyperactive delirium, were associated with a significantly higher risk of prolonged mechanical ventilation. Prolonged mechanical ventilation patients had a significant increase in intensive care unit mortality (absolute difference = 14.2%, p < 0.001) and hospital mortality (absolute difference = 19.1%, p < 0.001). The prolonged mechanical ventilation group spent more days in the hospital after intensive care unit discharge (26.9 ± 29.3 versus 10.3 ± 20.4 days, p < 0.001) with higher costs.

CONCLUSION

The classification of chronically critically ill patients according to the definition of prolonged mechanical ventilation adopted by our study (mechanical ventilation dependency ≥ 21 days) identified patients with a high risk for complications during intensive care unit stay, longer intensive care unit and hospital stays, high death rates, and higher costs.

Developing a critical care bowel management assessment tool to manage faecal incontinence

BACKGROUND

Critical care patients with faecal incontinence are at high risk of developing moisture lesions, pressure ulcers and secondary infection.

AIMS

The aims of this quality improvement programme were to identify the level of harm caused by faecal incontinence in critical care, and to review current critical care nursing practice on the use of bowel management systems, with the intent to implement changes to prevent delayed insertion.

THE IMPROVEMENT PROGRAMME

A four-step approach was used to guide the improvement programme. A total of seven case studies across three critical care units were reviewed and information was collected on stool type and frequency, duration of diarrhoea and skin integrity prior to bowel management system insertion.

DISCUSSION

Critical care nurses may not always use a consistent approach to the assessment of patients at risk of moisture or pressure damage due to faecal incontinence. Lack of knowledge about the maintenance of bowel management systems was viewed as a likely reason for the inconsistent approach. A Critical Care Bowel Management Assessment Tool was created, to contribute towards a more standardised approach to bowel assessment and management.

CONCLUSIONS

Inadequate assessment and management of faecal incontinence may have implications for critically ill patients. Further evaluation is required in order to demonstrate over time whether the changes made, as a result of this quality improvement programme, have led to sustainable improvement.

Bacteremic skin and soft tissue infection caused by Prevotella loescheii

Background

Anaerobes are a major component of gut flora. They play an important role in the pathogenesis of infections resulting from breaches in mucus membranes. Because of the difficulties in cultivating and identifying it, their role continues to be undermined. The purpose of this paper is to report a case of Prevotella loescheii bacteremic skin and soft tissue infection and review the literature.

Case presentation

A 42-year-old Caucasian man was admitted for an elective bariatric surgery. A lengthy intensive care unit stay and buttocks decubitus ulcers complicated his post-operative course. After being transferred to a long-term care facility, the decubitus ulcer became secondarily infected with multiple bacteria including P. loescheii; an anaerobe that grew in blood and wound cultures. The patient was treated successfully with aggressive surgical debridement, antibiotics and subsequent wound care.

Conclusion

P. loescheii colonizes the gut and plays an important role in periodontal infections. In rare occasions and under suitable circumstances, it can infect skin and soft tissues as well as joints. Given the difficulties in isolating anaerobes in the microbiology lab, considering this bacterium alongside other anaerobes in infections of devitalized tissue is indicated even if cultures were reported negative.

Prediction of chronic critical illness in a general intensive care unit

OBJECTIVE

To assess the incidence, costs, and mortality associated with chronic critical illness (CCI), and to identify clinical predictors of CCI in a general intensive care unit.

METHODS

This was a prospective observational cohort study. All patients receiving supportive treatment for over 20 days were considered chronically critically ill and eligible for the study. After applying the exclusion criteria, 453 patients were analyzed.

RESULTS

There was an 11% incidence of CCI. Total length of hospital stay, costs, and mortality were significantly higher among patients with CCI. Mechanical ventilation, sepsis, Glasgow score <15, inadequate calorie intake, and higher body mass index were independent predictors for CCI in the multivariate logistic regression model.

CONCLUSIONS

CCI affects a distinctive population in intensive care units with higher mortality, costs, and prolonged hospitalization. Factors identifiable at the time of admission or during the first week in the intensive care unit can be used to predict CCI.

Regional anaesthesia with sedation protocol to safely debride sacral pressure ulcers

A treatment challenge for patients with sacral pressure ulcers is balancing the need for adequate surgical debridement with appropriate anaesthesia management. We are functioning under the hypothesis that regional anaesthesia has advantages over general anaesthesia. We describe our regional anaesthesia protocol for perioperative and postoperative management.

Clinical and critical care concerns in severely ill obese patient

The incidence of obesity has acquired an epidemic proportion throughout the globe. As a result, increasing number of obese patients is being presented to critical care units for various indications. The attending intensivist has to face numerous challenges during management of such patients. Almost all the organ systems are affected by the impact of obesity either directly or indirectly. The degree of obesity and its prolong duration are the main factors which determine the harmful effect of obesity on human body. The present article reviews few of the important clinical and critical care concerns in critically ill obese patients.

Anesthesia protocol for heel pressure ulcer debridement

Heel ulcers are clinically challenging. Limited subcutaneous tissue covering the calcaneus bone makes the heel vulnerable to pressure injury. Adequate debridement of fibrotic, infected, and necrotic tissue is essential for healing. The authors report a standardized anesthesia protocol using regional anesthesia with sedation rather than general anesthesia for heel debridement.

[Endonasal tubes as cause of pressure ulcers in the critical patient]

INTRODUCTION

One of the risks of using endonasal tubes (ET) is the appearance of pressure ulcers (PU).

OBJECTIVE

To ascertain the proportion of patients with nasal PU, study the risk factors of appearance, and find predictive variables.

MATERIAL AND METHODS

A six-month prospective, observational study of intensive care unit patients with ET.

VARIABLES

Variable response: "the appearance of pu as a result of the use of ET". Explanatory variables: age, duration of stay, length of time with ET, gender, sedation, norepinephrine perfusion, mechanical ventilation, anemia, nutritional state.

ANALYSIS

multivariate statistical techniques (multiple logistical regression). Statistics program g-stat 2.0. Significance level p < 0.05.

RESULTS

Sample of 48 patients. Proportion of patients with PU: 29.2%. Those patients with PU had similar ages, duration of stay and longer length of time with ET. Results of the Logistic Regression model: only the variable "time with ET" was statistically significant (p = 0.03; odds ratio: 1.047).

CONCLUSIONS

The length of time the patient is using an ET influences the appearance of nasal PU (risk increases 1.047 for each day with ET). None of the variables dealt with could be used as a predictive factor in the appearance of PU.

Nutrition support and the chronic critical illness syndrome

Critical illness can be viewed as consisting of 4 distinct stages: (1) acute critical illness (ACI), (2) prolonged acute critical illness, (3) chronic critical illness, and (4) recovery. ACI represents the evolutionarily programmed response to a stressor. In ACI, substrate is shunted away from anabolism and toward vital organ support and inflammatory proteins. Nutrition support in this stage is unproven and may ultimately prove detrimental. As critical illness progresses, there is no evolutionary precedent, and man owes his life to modern critical care medicine. It is at this point that nutrition and metabolic support become integral to the care of the patient. This paper (1) delineates and develops the 4 stages of critical illness using current evidence, clinical experience, and new hypotheses; (2) defines the chronic critical illness syndrome (CCIS); and (3) details an approach to the metabolic and nutrition support of the chronically critically ill patient using the metabolic model of critical illness as a guide. It is our hope that this clinical model can generate testable hypotheses that can improve the outcome of this unique population of patients.

Ventilator-Dependent Survivors of Catastrophic Illness Transferred to 23 Long-term Care Hospitals for Weaning From Prolonged Mechanical Ventilation

STUDY OBJECTIVES

This multicenter study was undertaken to characterize the population of ventilator-dependent patients admitted to long-term care hospitals (LTCHs) for weaning from mechanical ventilation.

DESIGN

Observational study with concurrent data collection. Characteristics of the LTCHs were also surveyed.

SETTING

Twenty-three LTCHs in the United States.

PATIENTS

Consecutive ventilator-dependent patients admitted over a 1-year period: March 1, 2002, to February 28, 2003.

RESULTS

A total of 1,419 patients were enrolled in the Ventilation Outcomes Study. Median age of the patients was 71.8 years old (range, 18 to 97.7 years), with an equal gender distribution. The premorbid domicile was home or assisted living in 86.5%; "good" premorbid functional status (Zubrod score 0-2) was assessed in 77%. There was a history of smoking in 59% (mean, 57 +/- 42 pack-years [+/- SD]); premorbid diagnoses averaged 2.6 per patient. Patients came to the LTCH after mean of 33.8 +/- 29 days at the transferring hospital; mean time to tracheotomy was 15.0 +/- 10 days. A medical illness led to ventilator dependency in 60.8% of patients; a surgical procedure led to ventilatory dependency in 39.2%. On admission to the LTCH, the median acute physiology score of APACHE (acute physiology and chronic health evaluation) III was 35 (range, 4 to 115); > 90% of patients had at least three penetrating indwelling tubes/catheters; 42% of patients had stage 2 or higher pressure ulceration.

CONCLUSIONS

This is the first multicenter study to characterize ventilator-dependent survivors of catastrophic illness admitted to the post-ICU venue of LTCHs for weaning from prolonged mechanical ventilation (PMV). Overall, our findings suggest that ventilator-dependent patients admitted to LTCHs for weaning will continue to require considerable medical interventions and treatments, owing to the burden of acute-on-chronic diseases resulting in PMV.

Skin Fails Too

OBJECTIVE

To identify what has been published in the literature about acute and chronic skin failure and to propose a working definition of this phenomenon.

DESIGN

A systematic review of MEDLINE and CINAHL to determine what has been published in the literature on the topics of skin failure, acute skin failure, chronic skin failure, multiple organ failure, end-of-life skin deterioration, and pressure ulcers in hospice from 1984 to 2005.

MAIN OUTCOME MEASURES

Published papers were reviewed for content related to acute, chronic, and end-stage skin failure.

MAIN RESULTS

Seven articles were identified that referenced either acute, chronic, or end-stage skin failure. Additional information was identified that discussed the processes of acute and chronic skin failure and pressure ulcers in individuals in hospice care or at the end of life. Care considerations and dilemmas related to a curative versus palliative goal in wound healing were discussed.

CONCLUSIONS

Minimal literature exists on skin failure, yet caregivers and the public must be aware of, assess for, and consider this phenomenon in their care. Based on this literature review, skin failure was defined by the authors as an event in which the skin and underlying tissue die due to hypoperfusion that occurs concurrent with severe dysfunction or failure of other organ systems. Skin failure can be categorized as acute, chronic, or end stage. Pressure ulcers, a type of skin death, frequently occur in persons with a heavy disease burden, especially those at or near the end of life, despite good care.

Wound Documentation: Managing Risk

PURPOSE

To provide the physician and registered professional nurse with an understanding of consistent wound documentation and the potential for legal issues to arise.

TARGET AUDIENCE

This continuing education activity is intended for physicians and nurses with an interest in better understanding and improving policies and procedures related to wound documentation.

OBJECTIVES

After reading the article and taking the test, the participant should be able to: 1. Discuss wound assessment and documentation relative to current practices and potential legal implications. 2. Describe recommendations to improve the consistency and accuracy of wound assessment and documentation.

SimCair: a simple mattress system to support pressure ulcer prevention

Assessing skin is a simple method of reducing pressure ulcer occurrence and is easily accomplished by both trained and untrained staff. The important issue, once the risk has been identified, is to supply equipment in the shortest time possible. A new mattress, SimCair, developed by Hill-Rom Ltd, is designed for just such a reason. It is a lightweight overlay that combines air and viscoelastic foam in order to redistribute the body weight and thus reduce risk. SimCair is easily transported and can be ready for instant and automatic inflation as soon as it is required. It is also durable and simple to clean between patients. A small evaluation was undertaken in one nursing home to assess the benefits to the residents.

Assessing persistent pain and its relation to affective distress, depressive symptoms, and pain catastrophizing in patients with chronic wounds: a pilot study

OBJECTIVE

The purpose of this study was to examine pain experience among patients with chronic wounds, assess the utility of pain assessment scales for chronic wound-related pain, and determine the relation of wound-related pain to wound stage, affective distress, depressive symptoms, and pain catastrophizing.

DESIGN

In this cross-sectional study of patients with a mix of chronic wounds (n = 69) recruited for a study evaluating a telemedicine system for assessing chronic wounds, 19 men (12 with spinal cord injury) with wound-related pain were identified. Questionnaires included the Numerical Pain Rating Scale, McGill Pain Questionnaire, Brief Symptom Inventory, Center for Epidemiologic Studies Depression Scale, and the catastrophizing scale of the Coping Strategies Questionnaire.

RESULTS

The McGill Pain Questionnaire was more sensitive to pain experience than a single rating of pain intensity. Wound stage was positively related to severity of pain. Pain catastrophizing was positively related to pain intensity and higher levels of affective distress and depressive symptoms.

CONCLUSIONS

Pain associated with chronic wounds is a significant clinical challenge for both patients and health practitioners.

Protocol for the successful treatment of pressure ulcers

Bed-bound patients with pressure ulcers are almost twice as likely to die as are those without pressure ulcers. If pressure ulcers are treated with a comprehensive regimen upon early recognition, nearly all stage IV ulcers can be avoided. Furthermore, such a regimen can significantly reduce the comorbidities, mortalities, and costs of treatments resulting from stage IV ulcers. The costs of treatments for comorbidities after the ulcer progresses to stage IV far outweigh the costs for early treatment of the ulcer before it progresses beyond the early stages. We describe herein the 4 stages of pressure ulcers, as well as the pathogeneses, costs, and complications associated with these wounds. A comprehensive 12-step detailed protocol for treatment of pressure ulcers is described; this includes recognizing that every patient with limited mobility is at risk for developing a sacral, ischial, trochanteric, or heel ulcer; daily assessment of the skin; objective measurement of every wound; immediate initiation of a treatment protocol; mechanical debridement of all nonviable tissue; establishment of a moist wound-healing environment; nutritional supplementation for malnourished patients; pressure relief for the wound; elimination of drainage and cellulitus; biological therapy for patients whose wounds fail to respond to more traditional therapies; physical therapy; and palliative care. Availability of the described treatment modalities, in combination with early recognition and regular monitoring, ensures rapid healing and minimizes morbidity, mortality, and costs.

TheraPulse ATP for preventing and treating pressure ulcers

In the modern healthcare environment where evidence-based best practice is key in seeking quality improvements for patient care, using treatment and therapies that have evidence of clinical efficacy is paramount. The current evidence bases supporting pulsating air suspension therapy is excellent and the improved lymphatic flow and enhanced microcirculation along with reduction of pressure ulcer potential (El-Habbal and Smith, 1996; Gunther and Brofeldt, 1996) ensures a firm place for TheraPulse ATP (KCI Medical) in reduction of oedema and pressure ulcers in the critically ill patient.

The QUATTRO ACUTE mattress and pressure ulcer prevention

There are a plethora of mattresses on the market and nurses are not always sure which mattress to select for each individual patient. This article outlines the issues in preventing and understanding pressure ulcers and the performance of the QUATTRO ACUTE trade mark mattress, manufactured by Talley Medical.
