Do pressure ulcers influence length of hospital stay in surgical cardiothoracic patients? A prospective evaluation

Aim and objective. The aim and objective of this study was to determine whether the occurrence of pressure ulcers following cardiothoracic surgery increases the length of hospitalisation. Background. Literature suggests that a pressure ulcer extends the length of hospital stay. The impact of pressure ulcers on length of hospital stay after cardiothoracic surgery is yet undetermined. Design. Prospective follow‐up study. Methods. Two hundred and four patients admitted for elective cardiothoracic surgery and with an intensive care unit stay of >48 hours were included in a prospective cohort study. The course of the skin condition in relation to pressure ulcers was monitored during their stay in a teaching hospital. Length of hospital stay was compared between the group with and without pressure ulcers. Results. Hospital stay for cardiothoracic patients with and without pressure ulcers did not differ significantly (p = 0·23). Patients that developed pressure ulcers had a median hospital stay of 13 days (interquartile range: 9–19) vs. 12 days (interquartile range: 7–15) for patients without pressure ulcers. However, we observed that length of stay in the intensive care unit was significantly (p = 0·005) longer for patients with pressure ulcers. This was not associated with the occurrence of complications. However, the occurrence of pressure ulcers was significantly correlated with length of intensive care support in postoperative care. Conclusion. Non‐complicated pressure ulcers in postsurgery patients do not significantly increase the length of total hospital stay. Relevance to clinical practice. Health professionals need to recognise that patients who have undergone major surgery (such as cardiothoracic surgery) are prone to develop pressure ulcers. Despite the fact that pressure ulcers do not necessarily extend hospital stay, monitoring the skin condition remains of crucial importance for prevention and early detection as well as treatment of pressure ulcers and to minimise patient discomfort. Moreover, as pressure ulcers often originate in the operating room, prevention in the operating room should receive more attention.     

Patterns of recurrent pressure ulcers after spinal cord injury: identification of risk and protective factors 5 or more years after onset

OBJECTIVES: To identify risk and protective factors associated with a history of recurrent pressure ulcers among participants with spinal cord injury (SCI). DESIGN: A mail survey was used to identify factors associated with the presence or absence of recurrent pressure ulcers. SETTING: A large specialty hospital in the southeastern United States. PARTICIPANTS: All participants had traumatic SCI, were nonambulatory, 18 years or older, and had been injured at least 5 years. A total of 826 subjects participated, 633 of whom reported a pressure ulcer history that could be classified as to whether they did or did not have a history of recurrent pressure ulcers. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: History of pressure ulcers was measured by a single item that required participants to classify their history into 1 of 5 options, ranging from never having any pressure ulcers to having almost continuous pressure ulcers, often requiring hospitalization. Those who either never had a pressure ulcer or had them mostly for a short period after SCI onset were classified as nonrecurrent, whereas those who reported at least 1 per year were classified as recurrent. RESULTS: Seventy percent of the participants failed to report recurrent pressure ulcers (never had any or had them only immediately after SCI onset), whereas 13% reported a clear pattern of recurring pressure ulcers of 1 or more per year. Logistic regression analyses suggested several general behaviors were protective for recurrent pressure ulcers, including lifestyle, exercise, and diet. Yet none of the behaviors generally recommended during inpatient rehabilitation specifically to prevent pressure ulcers (eg, skin checks weight shifts) were associated with pressure ulcer history. Only 2 risk behaviors were identified (number of cigarettes smoked, use of medication for sleep), although several proxy variables were related to pressure ulcer history. CONCLUSIONS: Pressure ulcer history is a more viable measure of pressure ulcer outcomes than measures taken at a single point in time (current), over a brief period (eg, 1y), or those relying on critical events occurring at any time since SCI onset (ie, surgeries to repair pressure ulcers). A healthy lifestyle appears to be strongly associated with avoiding pressure ulcers, whereas the efficacy of specific prevention behaviors was not demonstrated. Problem solving and coping strategies should be targets for further research.     

Employment after spinal cord injury

A predictive model for employment after spinal cord injury was developed. The study population consisted of 154 spinal cord injured persons who were treated at our hospital between 1973 and 1979, and followed for seven years after injury. Demographic, social, and injury severity data were abstracted from each subject's hospital record. Motivation to work, employment history, and sources of postinjury financial support, were assessed by a vocational rehabilitation counselor. The study population was divided into four groups: persons continuously unemployed after injury, homemakers, students, and those employed at some time during the seven-year follow-up period. Stepwise discriminant analysis was used to develop a predictive model that ultimately included seven variables: gender, motivation to work, whether the patient's last job required ambulation, race, educational level, a functional ability score, and whether the patient had children. The model correctly classified 82% of those persons who were continuously unemployed, 100% of homemakers, 63% of students, and 72% of employed subjects. Overall, 79% of subjects were classified correctly. The most important classification errors were between the unemployed and employed groups. Seventeen percent of employed patients were incorrectly classified as unemployed, and 11% of unemployed patients were incorrectly classified as employed. Although there are other determinants of postinjury vocational status, individual potential can be assessed by means of a comparatively small set of predictor variables.     

Braden量表在足部压疮风险预测中的应用

目的评估Braden量表在足部压疮风险预测中的诊断价值。方法采用病例对照研究的方法,选择温州市某三级甲等医院124例臀部压疮患者和52例足部压疮患者作为压疮组,选取未发生任何部位压疮的患者120例作为对照组。应用Braden量表分别对两组患者进行诊断分析,通过灵敏度、特异度、ROC曲线等指标评价Braden量表在足部压疮风险预测中的诊断价值。结果臀部压疮组与足部压疮组患者的疾病诊断及压疮分期差异有统计学意义(P<0.01)。足部压疮组的平均Braden评分高于臀部压疮组,差异有统计学意义(P<0.05)。Braden量表预测臀部压疮的灵敏度为54.0%,ROC曲线下面积为0.756;预测足部压疮的灵敏度为40.4%,ROC曲线下面积为0.674。结论 Bra-den量表预测足部压疮风险尚存在不足。     

Nontraumatic spinal cord injury rehabilitation: pressure ulcer patterns, prediction, and impact

OBJECTIVE: To investigate the characteristics, predictors, and consequences of pressure ulcers in patients with nontraumatic spinal cord injury (SCI). DESIGN: Retrospective, 3-year, case series. SETTING: Tertiary medical unit specializing in SCI rehabilitation. PARTICIPANTS: Consecutive sample of 134 adult inpatient referrals with nontraumatic SCI. Patients requiring initial rehabilitation or readmission were included. INTERVENTION: Chart review. MAIN OUTCOME MEASURES: Primary outcome measures were presence of pressure ulcers on admission to rehabilitation, incidence of new pressure ulcers developing during hospitalization, and any complications attributable to pressure ulcers during inpatient rehabilitation. Secondary objectives were to examine the predictability of risk factors for pressure ulcers, to assess the usefulness of a model previously developed for predicting pressure ulcers in patients with chronic SCI, and to estimate the effect of pressure ulcers on rehabilitation of nontraumatic SCI. RESULTS: Prevalence of pressure ulcers among admissions was 31.3% (n=42). Only 2.2% (n=3) of patients developed a new pressure ulcer after admission. The length of stay (LOS) of patients admitted with a pressure ulcer was significantly longer than that of those without a pressure ulcer (geometric mean, 62.3 d for pressure ulcer vs 28.2 d for no pressure ulcer, P=.0001). Many previously identified risk factors for pressure ulcers in SCI patients did not apply to our nontraumatic SCI patients. It is estimated that the inpatient LOS for those patients with a significant pressure ulcer was increased by 42 days. CONCLUSIONS: Pressure ulcers are a common complication for people with nontraumatic SCI who are admitted for rehabilitation, and they have a significant impact on LOS.     

An audit of pressure ulcer incidence in a palliative care setting

This article reports a continuous audit of pressure ulcer incidence within a specialist palliative care unit over 2 years. Details of every patient admission were considered (542 patients). Of these, 26.1% were admitted with pressure ulcers while 12.0% developed pressure damage during their stay. The retrospective audit looked at the ulcers developing in the unit and found these patients were older, stayed 12 days longer and more of them died than the average for all patients admitted to the unit. In total, 95.3% were accurately assessed at 'high' or 'very high' risk using the Waterlow (1985) Pressure Sore Risk Assessment Tool and 89.2% of ulcers were Grade 1 or 2 measured using the Stirling Pressure Sore Severity Scale (Reid and Morrison, 1994). Of all developing ulcers, 78.4% were sacral and the position of the tumour, as well as comfort and positioning difficulties were considered most often responsible. Despite this knowledge and many 'improvements' introduced, the incidence did not improve with superficial ulcers often developing in the last days of life.     

Incidence of pressure ulcers in a neurologic intensive care unit

OBJECTIVES: To determine the risk factors for pressure ulceration in an intensive care setting, to evaluate the Braden scale as a predictor of pressure ulcer risk in critically ill patients, and to determine whether pressure ulcers are likely to occur early in the hospital stay. DESIGN: Cohort study of patients with no preexisting ulcers with a 3-month enrollment period. SETTING: The neurologic intensive care unit and the neurologic intermediate unit at a primary care/referral hospital with a level I trauma center. PATIENTS: A total of 186 patients entered the study. INTERVENTION: Within 12 hrs of admittance, initial assessment, photographs, and Braden score were completed. Patients were re-examined every 4 days or at discharge from the unit, whichever came first. MAIN OUTCOME MEASURES: Determining risk factors for pressure ulcers, performing detailed statistical analyses, and testing the usefulness of the Braden score as a predictor of pressure ulcer risk. RESULTS: Twenty-three of 186 patients developed at least one pressure ulcer (incidence = 12.4%) after an average stay of 6.4 days. The Braden scale, which measures six characteristics of skin condition and patient status, proved to be a primary predictor of ulcer development. No ulcers developed in the 69 patients whose Braden score was 16 or higher. The likelihood of developing a pressure sore was predicted mathematically from the Braden score. However, being underweight was a significant and distinct factor in pressure ulcer development. CONCLUSIONS: Pressure ulcers may develop within the first week of hospitalization in the intensive care unit. Patients at risk have Braden scores of < or = 16 and are more likely to be underweight. These results suggest that aggressive preventive care should be focused on those patients with Braden scores of < or = 13 and/or a low body mass index at admission.     

Prevalence, risk factors and prevention of pressure ulcers in Dutch intensive care units

OBJECTIVE: Evaluating the prevalence, risk factors and prevention of pressure ulcers in Dutch intensive care units (ICUs). DESIGN: Cross-sectional design. SETTING: ICUs of acute care hospitals that participated in the 1998 and 1999 national prevalence surveys. Data were collected on 1 day in each year. PATIENTS: Eight hundred fifty patients admitted to Dutch ICUs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Six categories of data were collected: (1) characteristics of the institution, (2) characteristics of the ward, (3) characteristics of the patients (age, sex, date of admission, reason for admission), (4) risk assessment using the Braden scale and two additional risk factors (malnutrition and incontinence), (5) severity of the pressure ulcers and (6) supportive surface used. The prevalence of pressure ulcers was 28.7%. In a forward logistic regression analysis, four risk factors were significantly associated with the presence of pressure ulcers: infection, age, length of stay and total Braden score. Of the patients at high risk of developing pressure ulcers but without actual pressure ulcers, 60.5% were positioned on a support system. Only 36.8% of the patients who were determined to need repositioning were actually being turned. CONCLUSIONS: The prevalence of pressure ulcers in Dutch ICUs is high and their prevention is flawed, especially as regards the use of support systems. Patients for whom turning is indicated are not being turned. Predicting pressure ulcers in ICU patients is difficult and needs further investigation.     

A Prediction Rule to Identify Low-risk Patients with Heart Failure

Objectives: To derive a prediction rule using data available in the emergency department (ED) to identify a group of patients hospitalized for the treatment of heart failure who are at low risk of death and serious complications. Methods: The authors analyzed data for all 33,533 patients with a primary hospital discharge diagnosis of heart failure in 1999 who were admitted from EDs in Pennsylvania. Candidate predictors were demographic and medical history variables and the most abnormal examination or diagnostic test values measured in the ED (vital signs only) or on the first day of hospitalization. The authors constructed classification trees to identify a subgroup of patients with an observed rate of death or serious medical complications before discharge < 2%; the tree that identified the subgroup with the lowest rate of this outcome and an inpatient mortality rate < 1% was chosen. Results: Within the entire cohort, 4.5% of patients died and 6.8% survived to hospital discharge after experiencing a serious medical complication. The prediction rule used 21 prognostic factors to classify 17.2% of patients as low risk; 19 (0.3%) died and 59 (1.0%) survived to hospital discharge after experiencing a serious medical complication. Conclusions: This clinical prediction rule identified a group of patients hospitalized from the ED for the treatment of heart failure who were at low risk of adverse inpatient outcomes. Model performance needs to be examined in a cohort of patients with an ED diagnosis of heart failure and treated as outpatients or hospitalized.     

Risk factors and prevention among patients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital

Aims and objectives.  This study aimed to describe and identify risk factors associated with hospital‐acquired pressure ulcers among adults in an acute care hospital compared with patients with pre‐existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Background.  Pressure ulcers occur most often in older and immobile persons with severe acute illness and neurological deficits. However, few studies have addressed risk factors that are associated with hospital‐acquired pressure ulcers compared with patients with pre‐existing pressure ulcers. Design.  A point prevalence study with a cross‐sectional survey design was conducted at a Swedish university hospital. Method.  Data on 535 patients were recorded using a modified version of the protocol developed and tested by the European Pressure Ulcer Advisory Panel, including the Braden scale for risk assessment. Results.  The prevalence of pressure ulcers was 27% (95% confidence interval, 23–31%). Higher age and a total Braden score below 17 were significantly associated with the presence of pressure ulcers. Among individual risk factors higher age, limited activity level and friction and shear while seated or lying down were associated with hospital‐acquired pressure ulcers, whereas only higher age and friction and shear were associated with the presence of pressure ulcers in the overall sample. There was an overall sparse use of preventive measures to relieve pressure. Conclusion.  The findings of the present study revealed that pressure ulcers and the insufficient use of preventive measure to relieve pressure is still a problem in acute care settings. A continued focus must be placed on staff training in identifying patients at risk for pressure ulcers development. Relevance to clinical practice.  Increasing the ability to identify patients who are at risk for pressure ulcer development can assist in preventing unnecessary complications and suffering as well as reduce costs.     

Age-specific characteristics of patients who develop pressure ulcers in the tertiary-care setting

This article explores whether age-specific characteristics of patients who develop pressure ulcers in the tertiary-care setting are present at hospital admission. Characteristics of interest were prescribed activity, diet, and oxygen therapy; weight change in the last 30 days; midarm muscle circumference; triceps skin fold; and total protein, serum albumin, white blood cell count, hematocrit, and hemoglobin. The sample was composed of 67 subjects who developed pressure ulcers when hospitalized electively and admitted to the cardiovascular or neurosurgical services of a tertiary-care hospital. Chi square and analysis of variance were used to analyze the data and showed no significant difference in the characteristics of the two groups. Data did indicate that length of hospitalization and severity of illness are more important determinants of ulcer development than age-specific characteristics in this sample.     

Ambulatory care-sensitive conditions: clinical outcomes and impact on intensive care unit resource use

BACKGROUND: We identified risk factors and clinical outcomes associated with ambulatory care-sensitive conditions requiring intensive care unit (ICU) admission. METHODS: This prospective cohort study included 4,144 patients admitted to the medical ICU of an urban teaching hospital during a 3-year period. RESULTS: A total of 627 patients were classified as having ambulatory care-sensitive conditions (ie, potentially preventable ICU admissions). Black race, decreasing Acute Physiology and Chronic Health Evaluation II (APACHE II) score, younger age, female sex, and absence of immunodeficiency were independently associated with ambulatory care-sensitive conditions. Patients classified as having ambulatory care-sensitive conditions accounted for 2,006 ventilator days, 2,508 ICU days, and 5,392 hospital days. The hospital mortality rate was statistically lower for patients with ambulatory care-sensitive conditions than for patients without these conditions. Patients classified as having ambulatory care-sensitive conditions were also statistically more likely than other patients to lack health insurance and to sign out of the hospital against medical advice. CONCLUSION: Patients with ambulatory care-sensitive conditions account for a substantial portion of all admissions to the intensive care unit. These data suggest that interventions aimed at preventing such admissions could improve ICU bed use.     

Kinetic therapy reduces complications and shortens hospital stay in patients with cardiogenic shock - a retrospective analysis.

BACKGROUND: Kinetic therapy (KT) has been shown to reduce complications and to shorten hospital stay in trauma patients. Data in non-surgical patients are inconclusive, and kinetic therapy has not been tested in patients with cardiogenic shock. OBJECTIVE: The present analysis compares KT with standard care in patients with cardiogenic shock. METHODS: A retrospective analysis of 133 patients with cardiogenic shock admitted to 1 academic heart center was performed. Patients with standard care (SC, turning every 2 h by the staff) were compared with kinetic therapy (KT, using oscillating air-flotation beds). MEASUREMENTS AND MAIN RESULTS: 68 patients with KT were compared with 65 patients with SC. Length of ventilator therapy was 11 days in KT and 18 days in SC (p=0.048). The mortality was comparable in both groups. Pneumonia occurred in 14 patients in KT and 39 patients in SC (p<0.001); pressure ulcers were reduced by 50% (p<0.001). Length of ICU stay (21 days in SC and 13 days in KT, p=0.009) and length of hospital stay were reduced in the patients treated with kinetic therapy. CONCLUSION: The use of KT shortens hospital stay and reduces rates of pneumonia and pressure ulcers as compared to SC.     

Patient satisfaction associated with correct identification of physician's photographs

OBJECTIVE: To determine whether placement of photographs of physicians in hospital rooms improves patients' satisfaction with their medical care. PATIENTS AND METHODS: This is a prospective, controlled study of 224 patients admitted to general internal medicine services in a teaching hospital. The intervention consisted of photographs (8 x 10 in) of attending and resident physicians displayed in the patients' rooms. Before dismissal, patients completed a survey that required them to match names with photographs of physician caregivers and included patient satisfaction questions. The primary outcome was whether patients who had photographs in their hospital room would correctly identify more physicians than those with no photographs in their room. RESULTS: The presence of photographs on the hospital wall was associated with a significant improvement in the number of physicians identified correctly (odds ratio [OR], 1.83; 95% confidence interval [CI], 1.47-2.27; P<.001). The percentage of physicians that patients identified by correctly matching their physicians' names to their photographs was significantly associated with satisfaction with physician responsiveness (OR, 1.19; 95% CI, 1.01-1.40; P=.03) and with the way in which physicians addressed questions regarding medical care (OR, 1.23; 95% CI, 1.05-1.44; P=.05). CONCLUSIONS: Patients who had photographs of their physicians on the wall of their hospital room were able to identify correctly a larger number of physicians on their team compared with patients who had no photographs. Patient satisfaction was related to the number of physicians' photographs that patients could identify correctly.     

Inter-rater reliability and comfort in the application of a basic life support termination of resuscitation clinical prediction rule for out of hospital cardiac arrest

STUDY OBJECTIVE: This study evaluates inter-rater reliability and comfort of BLS providers with the application of an out-of-hospital Basic Life Support Termination of Resuscitation (BLS TOR) clinical prediction rule. This rule suggests that continued BLS cardiac resuscitation is futile and can be terminated in the field if the following three conditions are met: (1) no return of spontaneous circulation; (2) no shock given prior to transport; (3) cardiac arrest not witnessed by EMS personnel. METHODS: Providers hypothetically applied the rule and rated their comfort level on a five-point Likert-type scale, from "very comfortable" to "very uncomfortable" during the prospective validation of a BLS TOR clinical prediction rule in out-of-hospital cardiac arrest conducted in 12 rural and urban communities [Morrison LJ, Visentin LM, Kiss A, et al. Validation of a rule for termination of resuscitation in out-of-hospital cardiac arrest. New Engl J Med 2006;355(5):478-87]. A Kappa score measured agreement between providers and compared to the correct interpretation of the rule. RESULTS: We compared mean comfort levels of providers who interpreted the rule correctly versus incorrectly. Of 1240 enrolled cases, 1184 (95.5%) had paramedic attendant forms and 1211 (97.7%) had driver forms and 1175 (94.7%) had both. Kappa for interpretation agreement between driver and attendant was 0.90 (95% CI, 0.87-0.92); between attendant and correct interpretation of the BLS TOR clinical prediction rule, 0.88 (95% CI, 0.85-0.91); between driver and correct interpretation of the BLS TOR clinical prediction rule, 0.88 (95% CI, 0.85-0.91). For instances in which both providers applied the rule correctly (607/635 [95.6%]), the providers were significantly more comfortable (chi(2)(4)=30.5, p<0.0001) than those instances in which they did not (28/635 [4.4%]. CONCLUSIONS: The vast majority of providers were able to apply the BLS TOR clinical prediction rule correctly and were comfortable doing so. This suggests that both reliability and comfort will remain high during routine application of the rule when paramedics are well trained as users of the rule.     

Early Discharge of Patients with Presumed Opioid Overdose: Development of a Clinical Prediction Rule

OBJECTIVE: To develop a clinical prediction rule to identify patients who can be safely discharged one hour after the administration of naloxone for presumed opioid overdose. METHODS: Patients who received naloxone for known or presumed opioid overdose were formally evaluated one hour later for multiple potential predictor variables. Patients were classified into two groups: those with adverse events within 24 hours and those without. Using classification and regression tree methodology, a decision rule was developed to predict safe discharge. RESULTS: Clinical findings from 573 patients allowed us to develop a clinical prediction rule with a sensitivity of 99% (95% CI = 96% to 100%) and a specificity of 40% (95% CI = 36% to 45%). Patients with presumed opioid overdose can be safely discharged one hour after naloxone administration if they: 1) can mobilize as usual; 2) have oxygen saturation on room air of >92%; 3) have a respiratory rate >10 breaths/min and <20 breaths/min; 4) have a temperature of >35.0 degrees C and <37.5 degrees C; 5) have a heart rate >50 beats/min and <100 beats/min; and 6) have a Glasgow Coma Scale score of 15. CONCLUSIONS: This prediction rule for safe early discharge of patients with presumed opioid overdose performs well in this derivation set but requires validation followed by confirmation of safe implementation.     

Pressure ulcer research: where do we go from here?

The physiology and pathology of pressure defence mechanisms have been little studied and are not understood. No critical risk factors have been identified and populations of patients identified as being 'at risk' by risk calculators and clinical impression often have small numbers of patients who are really susceptible to pressure ulcers (PUs). Prevention trials must therefore have large sample sizes to enable significant results to be observed, or must be carried out in patient populations with a high PU incidence. Many trials have been carried out in orthopaedic patients but results may not be generalizable. Measurement of physical parameters (e.g. interface pressure), useful for adapting support surfaces for individual patients and designing new support systems, is unlikely to identify the aetiology of PUs and, without validation from clinical trials, predict the efficacy of interventions. In future it may be better to sample other groups, such as critical care patients for trials, as the findings might prove more generalizable. The effects of interventions should also be researched at the healthcare system level rather than that of product or risk factor. However, only the physiological study of PU aetiology is likely to advance our knowledge and ability to prevent PUs more effectively.     

Adverse effects prevalence study: pressure ulcers in an acute hospital

ObjectiveThe pressure ulcers (PU) are one of the adverse effects associated with hospitalisation. The aims of this study are, to determine the prevalence of PU in patients admitted to a tertiary hospital, to describe the characteristics of the injuries, to find out the frequency of use of special surfaces for managing pressure (SSMP), and to establish lines of action for their prevention.MethodThis is a cross-sectional study of adults patients admitted to hospital between May 11 and 15, 2009. Collected variables are: demographic data, number of PU, admission unit, risk level (measured by modified Gosnell′s scale), stage, location, cause, origin of the injury and SSMP.ResultsA total of 683 patients were studied, of which 70 (10.3%) of them had at least one wound. The risk of developing PU in patients evaluated as high risk, is more than those patients evaluated as no or low risk (OR: 6.26; 95% CI; 3.54–11.08; p<0.001).Most of the wounds they were stage i (39.1%) and stage ii (35.2%), located mostly in the heel and sacrum, and (83.8 %) of the PU were of hospital origin. Only 28.1% of the available SSMP were used.ConclusionsThe overall percentage of PU is greater than that reported in other studies, but with less severe injuries. Patients at risk need to be identified and early preventive measures applied. In our hospital the use of SSMP is low in relation to the number of patients at risk.
