ABSTRACT

STUDY DESIGN: A prospective cohort of patients with acute tetraplegia. OBJECTIVES: This study aimed to determine the feasibility of using mouthpiece ventilation (MPV) in the intensive care unit (ICU) for patients who are extubated after suffering an acute cervical spinal cord injury (CSCI). SETTING: ICU, Princess Alexandra Hospital, Brisbane Australia. METHODS: New admissions to ICU in the 14 months between April 2017 and June 2018 with a CSCI who underwent intubation were assessed for inclusion. MPV was provided to consenting participants (who were deemed likely to be able to maintain ventilation on their own) at the time of extubation and was utilised in addition to standard care while participants were awake. MPV settings, usage, and support hours to educate and facilitate MPV were collected. Feedback from participants and clinical staff was gathered throughout the study. Pre- and post-extubation measures of forced vital capacity (FVC), the frequency of endotracheal suction of sputum, and gas exchange using ventilation-perfusion ratios were recorded along with the incidence of reintubation. RESULTS: Fourteen participated in utilising MPV with 16 episodes of extubation. The average time per participant to have MPV titrated and bedside data collected was 178 minutes. Data from 16 episodes of extubation have been included. Three of the 14 participants failed initial extubation. Feedback from participants and clinicians has been positive and constructive, enabling MPV settings to be adapted to the person with acute CSCI during this pilot study. CONCLUSION: MPV is feasible to use post-extubation for people with CSCI in ICU. Pressure control mode MPV was deemed the most suitable for newly extubated acute CSCI patients. Intensive clinical support is required initially to provide education prior to MPV, and at the time of extubation for both patient and treating clinicians. Both report it to be a useful adjunct to ICU treatment.

ABSTRACT

BACKGROUND: Critical care outreach teams support ward staff to manage patients who are seriously ill or after discharge from the intensive care unit (ICU). Respiratory deterioration is a common reason for (re)admission to the ICU. Physiotherapists are health professionals with skills to address acute respiratory concerns. Experienced respiratory physiotherapists play a role in supporting junior clinicians, particularly in managing deteriorating patients on the ward. OBJECTIVES: The objective of this study was to evaluate a novel respiratory physiotherapy critical care outreach-style service. The primary objective was to describe service referrals and the patient cohort. Other objectives were to compare the effects of this model of care on ICU readmission rates to a historical cohort and explore clinician perceptions of the model of care and its implementation. METHODS: A new physiotherapy model of care worked alongside an existing nurse-led outreach service to support physiotherapists with the identification and management of patients at risk of respiratory deterioration or ICU (re)admission. Purpose-built and pre-existing databases were used for prospective data collection and for a historical ICU readmissions control group. Questionnaires and semistructured group interviews were utilised to evaluate clinician satisfaction and perceptions. RESULTS: The service accepted referrals for 274 patients in 6 months (on average 2.25/working day; commonly after trauma [29%] and abdominal surgery [19%]). During the implementation period of the model of care, fewer preventable respiratory ICU readmissions were reported (n = 1/20) than in the historical cohort (n = 6/19: Fisher's exact test, p < 0.05). Likelihood of respiratory ICU readmission, compared to all-cause readmissions, was not affected (intervention: 31%, historical control: 41%; odds ratio: 0.63 [95% confidence interval: 0.29 to 1.4]). Postimplementation surveys and focus groups revealed clinicians highly valued the support and perceived a positive impact on patient care. CONCLUSIONS: Critical care outreach-style physiotherapy services can be successfully implemented and are positively perceived by clinicians, but any effect on ICU readmissions is unclear.

ABSTRACT

BACKGROUND: Burn injury is responsible for both acute and ongoing inflammation, resulting in systematic changes impacting the cardiovascular, hepatobiliary, endocrine, and metabolic systems, but there is minimal investigation into long-term clinical outcomes. This study aimed to investigate mortality due to cardiovascular related long-term postburn injury. METHODS: This was a retrospective cohort study linking a burns unit database with mortality outcomes from a Registry of Births, Deaths and Marriages. Data were extracted from the Australian Institute of Health and Welfare and stratified into three age groups: 15 to 44 years, 45 to 64 years, and 65+ years. Mortality rate ratios (MRRs) and 95% confidence interval (CI) were calculated to compare the burns cohort mortality incidence rates with the national mortality incidence rates for each of the three age groups. Logistic regression was used to identify demographic and clinical factors associated with cardiovascular mortality. RESULTS: A total of 4,134 individuals in the database were analyzed according to demographic and clinical variables. The 20-year age-standardized cardiovascular mortality rate for the burns cohort was significantly higher compared with the Australian population (250.6 per 100,000 person-years vs. 207.9 per 100,000 person-years) (MRR, 1.21; 95% CI, 1.001-1.45). Cardiovascular mortality was significantly higher in males aged 15-44 and 45-64 years had a cardiovascular mortality rate significantly higher than the Australian population (MRR = 10.06, 95% CI 3.49-16.63), and (MRR = 2.40, 95% CI 1.42-3.38) respectively. Those who died of cardiovascular disease were more frequently intubated postburn injury ( p = 0.01), admitted to intensive care ( p < 0.0001), and had preexisting comorbid physical conditions (60.9% vs. 15.0%, p < 0.0001). CONCLUSION: Survivors from burn injury, especially young males, are at increased long-term risk of death from cardiovascular disease. Increased screening and counseling pertaining to lifestyle factors should be standard management postburn injury. Longitudinal observation of physiological changes, investigation of mechanistic factors, and investigation of interventional strategies should be instituted. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level IV.

ABSTRACT

AIM: To determine if treadmill training embedded in self-management education commencing during stroke inpatient rehabilitation results in more physical activity than usual gait training. METHOD: A prospective, parallel-group, randomized trial with concealed allocation, blinded measurement, and intention-to-treat analysis involving 119 stroke survivors undergoing rehabilitation who were able to walk independently was undertaken. The experimental group undertook treadmill training (40-60% heart rate reserve) and self-management education for 30 min, three times a week for 8 weeks, and the control group undertook the same amount of usual gait training. Outcomes were measured at baseline (Week 0), on completion of the intervention (Week 8), and beyond the intervention (Week 26). The primary outcome was physical activity measured as steps/day using an activity monitor. Secondary outcomes were walking ability, cardiorespiratory fitness, cardiovascular risk, depression, self-efficacy, perception of physical activity, participation, and quality of life. RESULTS: After 8 weeks, the experimental group took 1436 more steps/day (95% confidence interval (CI) = 229 to 2643) than the control group. By 6 months, they took 871 more steps/day (95% CI -385 to 2129) than the control group. There was no difference between groups in any other outcome. CONCLUSION: In individuals undergoing rehabilitation after stroke, 8 weeks of treadmill training embedded in self-management resulted in more physical activity than usual gait training and this was largely maintained at 6 months, despite little effect on walking or cardiorespiratory fitness, suggesting the self-management was responsible.

ABSTRACT

BACKGROUND: Physical activity undertaken by stroke survivors is generally low. This trial investigated the feasibility of delivering a high-intensity treadmill and self-management program to people with stroke undergoing inpatient rehabilitation and determine whether physical activity, walking ability and cardiorespiratory fitness could be increased. METHOD: A phase I, single-group, pre-post intervention study was conducted with stroke survivors undergoing inpatient rehabilitation who could walk. Participants undertook a high-intensity treadmill and self-management program for up to 30 min, three times a week for 8 weeks under the supervision of their usual physiotherapist. Feasibility was determined by examining compliance, satisfaction and adverse events. Clinical outcomes were amount of physical activity, walking ability, and cardiorespiratory fitness collected pre-training (week 0), post-training (week 8), and at follow-up (week 26). RESULTS: Forty stroke survivors participated, completing 10 (SD 6) sessions, 94% at the specified training intensity, with high satisfaction and no adverse events related to the intervention. At week 8, participants completed 2749 steps/day (95% CI 933 to 4564) more physical activity than at week 0. Walking distance increased by 110 m (95% CI 23 to 196), walking speed by 0.24 m/s (95% CI 0.05 to 0.42), and VO2 peak by 0.29 ml/kg/min (95% CI 0.03 to 0.56). At week 26, increases in physical activity, walking distance and speed, and cardiorespiratory fitness were maintained. CONCLUSIONS: A high-intensity treadmill training program embedded within a self-management approach during inpatient rehabilitation appears feasible and potentially may offer sustained improvements in physical activity, walking ability, fitness, and quality of life. A randomised trial is warranted. TRIAL REGISTRATION: This feasibility study was registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12613000764730 ).

ABSTRACT

INTRODUCTION: Exercise-based interventions have been used to enhance the recovery of burn patients affected by hypermetabolism, muscle wasting and contractures. Although the benefits of exercise in burn population have been previously reported, the extent of exercise prescription in burn patients worldwide remains unknown. Therefore, the purpose of this study is to identify the extent and characteristics of exercise use in specialised and non-specialised burn centres worldwide. METHODS: A web-based survey was developed in English and translated into Spanish and Chinese languages. Distribution of the surveys was made via email using personal contacts of the authors and through six scientific societies related to burn care in 2018. Data were analysed using descriptive statistics and comparisons between frequency distribution on variables of interest using the Chi-Square test and contingency tables. RESULTS: One hundred and fifty-six surveys were completed (103 from the English version, 20 from the Chinese version, and 33 from the Spanish version). The response rate varied from 36.2% (English version) to 9.3% (Chinese version). Fifty eight percent of the surveyed clinicians worked in cities of 1 million inhabitants or more, and 92.3% worked in hospital-based burn centres. Exercise was used by 64.1% of the participants at the intensive care unit level, 75% in burn wards prior to complete wound healing, and 80.1% in rehabilitation units after wound healing. The type of exercise offered, parameters assessed, and characteristics of exercise programs varied notably among burn centres and clinicians consulted. CONCLUSION: The majority of the surveyed clinicians used exercise for rehabilitation of patients following burn injuries. Further investigation is required to elucidate the access to exercise interventions prescribed by health professionals in remote areas, in less developed countries, and the extent of home-based exercise performed by patients.

ABSTRACT

BACKGROUND: Although exercise capacity improves postheart transplantation (HTx), it remains unclear if the level of physical activity (PA) shows similar improvement. The purpose of this study was to (1) describe PA levels and (2) identify factors which may be associated with levels of PA post-HTx. METHODS: A prospective observational cross-sectional study was conducted at a single center HTx outpatient clinic. Medically stable adult recipients 6 months or longer post-HTx were recruited. Physical activity level (PAL) and average daily time spent at least moderately active (≥3 metabolic equivalents) were estimated using a multisensor device. Factors investigated were demographic (age, sex, body mass index [BMI], time post-HTx, and reason for HTx), corticosteroid use, exercise capacity (6-min walk distance), and quadriceps muscle strength corrected for body weight (QS%). RESULTS: The mean post-HTx time of the 75 participants was 9.2 ± 7.0 years (0.5-26 y). Twenty-seven (36%) participants were classified as extremely inactive (PAL, <1.40), 26 (34.6%) sedentary (1.40 ≤ PAL ≤ 1.69), and 22 (29.3%) active (PAL, ≥1.70). Multivariable analysis showed greater QS% (ß = 0.004 (0.002-0.006) P = 0.001) to be independently associated with increased PAL. For increased time, 3 or more metabolic equivalents both greater QS% (ß = 0.0164 [0.003-0.029]; P = 0.014) and lower BMI (ß = -0.0626 [-0.115 to -0.0099]; P = 0.021) were independently associated. CONCLUSIONS: The degree of observed sedentary behavior post-HTx is surprising, with the majority of participants not reaching levels of PA recommended for health benefits. QS% and BMI were the only factors found to be independently associated with estimates of PA. Further quality trials are required to demonstrate the long-term benefits of regular PA and investigate ways of increasing adherence to PA post-HTx.

ABSTRACT

BACKGROUND: Aquatic exercise training may be suitable for people with stable heart failure (HF) to engage in physical activity. OBJECTIVES: Acceptability, experiences and preferences regarding aquatic and traditional land-based exercise training, were explored in people with HF. METHODS: As part of a comparative intervention study, participants completed a questionnaire assessing acceptability, benefits and challenges of aquatic compared to land-based programs. Semi-structured interviews explored participant experiences in greater depth. RESULTS: Forty-eight participants, (mean age 70 + /- 11 years), completed the questionnaire and 14 participated in semi structured interviews. Aquatic exercise was regarded as acceptable and beneficial. Motivators were similar for both programs and included: a skilled and compassionate workforce, tailored care, perceived health benefit, sense of safety and an inclusive and enjoyable environment. Few barriers were identified for either program. CONCLUSIONS: Aquatic and land-based exercise training are equally acceptable for people with stable HF and motivators are similar for both programs.

ABSTRACT

BACKGROUND: The level of physical activity undertaken by stroke survivors living in the community is generally low. The main objectives of the IMPACT trial are to determine, in individuals undergoing rehabilitation after stroke, if 8 weeks of high-intensity treadmill training embedded in self-management education (i) results in more physical activity than usual physiotherapy gait training and (ii) is more effective at increasing walking ability, cardiorespiratory fitness, self-efficacy, perception of physical activity, participation, and health-related quality of life as well as decreasing cardiovascular risk, and depression, at 8 and 26 weeks. METHODS: A prospective, two-arm, parallel-group, randomised trial with concealed allocation, blinded measurement and intention-to-treat analysis, will be conducted. 128 stroke survivors undergoing rehabilitation who are able to walk independently will be recruited and randomly allocated to either the experimental or control group, who will both undergo gait training for 30 min, three times a week for 8 weeks under the supervision of a physiotherapist. Outcomes will be measured at baseline (Week 0), on completion of the intervention (Week 8) and beyond the intervention (Week 26). This study has obtained ethical approval from the relevant Human Research Ethics Committees. DISCUSSION: Improving stroke survivors' walking ability and cardiorespiratory fitness is likely to increase their levels of physical activity. Furthermore, if education in self-management results in sustained high levels of physical activity, this should result in improved participation and quality of life. TRIAL REGISTRATION: This trial was registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12613000744752 ) on 4th July, 2013.

ABSTRACT

OBJECTIVES: To determine the effectiveness of different modalities of exercise and to evaluate the safety of exercise-based interventions post-burns. DATA SOURCES: Six databases were searched from inception to October 2017 using "burn," "exercise" and synonyms as keywords. Relevant authors, key journals and reference lists of included studies were hand-searched. REVIEW METHODS: Articles reporting on exercise interventions in patients post-burn and considering physical, physiological or psychological outcomes were considered. Two authors independently screened 2253 records and selected 19 articles for inclusion. The quality of the evidence was assessed at the study level and at the outcome level. RESULTS: Unbiased effect size estimators (pooled Hedges' g) with 95% confidence intervals (CIs) were calculated if there were two or more trials with homogeneous outcomes. There were no significant differences post-exercise training in VO2peak ( g = 0.99; 95% CI: -0.4 to 2.4: P = 0.18), resting energy expenditure ( g = -0.51; 95% CI: -1.99 to 0.97: P = 0.5) and muscle strength ( g = 0.51; 95% CI: -0.03 to 1.05: P = 0.07) between groups. Evidence suggested exercise had a beneficial effect on body composition ( g = 0.59; 95% CI: 0.05 to 1.14: P = 0.03), need of surgical release of contractures (risk ratio = 0.34; 95% CI: 0.2 to 0.7; P = 0.004) and health-related quality of life. However, a lack of evidence existed regarding the safety of exercise training post-burns. CONCLUSION: Limited evidence suggests that exercise has a beneficial effect on physical and physiological outcomes in patients post-burn. Further trials using high-quality methodology are required, with focus on reporting of adverse events, health-related quality of life and psychological outcomes.

ABSTRACT

INTRODUCTION/AIMS: To describe the processes of care for secretion clearance in adult, intubated and mechanically ventilated patients in Australian and New Zealand Intensive Care Units (ICUs). METHODS/RESULTS: A prospective, cross-sectional study was conducted through the Australian and New Zealand Intensive Care Society Clinical Trials Group (ANZICS CTG) Point Prevalence Program. Forty-seven ICUs collected data from 230 patients intubated and ventilated on the study day. Secretion clearance techniques beyond standard suctioning were used in 84/230 (37%) of patients during the study period. Chest wall vibration 34/84 (40%), manual lung hyperinflation 24/84 (29%), chest wall percussion 20/84 (24%), postural drainage/patient positioning 17/84 (20%) and other techniques including mobilisation 15/84 (18%), were the most common secretion clearance techniques employed. On average (SD), patients received airway suctioning 8.8 (5.0) times during the 24-h study period. Mucus plugging events were infrequent (2.7%). The additional secretion clearance techniques were provided by physiotherapy staff in 24/47 (51%) ICUs and by both nursing and physiotherapy staff in the remaining 23/47 (49%) ICUs. CONCLUSION: One-third of intubated and ventilated patients received additional secretion clearance techniques. Mucus plugging events were infrequent with these additional secretion clearance approaches. Prospective studies must examine additional secretion clearance practices, prevalence of mucus plugging episodes and impact on patient outcomes.

ABSTRACT

BACKGROUND: The hypermetabolic state after severe burns is a major problem that can lead to several pathophysiologic changes and produce multiple sequelae. Adrenergic blockade has been widely used to reverse these changes and improve outcomes in burned patients but has not been rigorously evaluated. The aim of this systematic review was to investigate the efficacy and safety of the use of adrenergic blockade after burn injury. METHODS: The databases MEDLINE via OVID, PubMed, EMBASE, CINAHL, Cochrane Library, and Web of Science were searched from inception to December 2014 with search terms including burns and beta-blockers with appropriate synonyms. Articles were restricted to those published in English, French, or Spanish. Randomized controlled trials, nonrandomized controlled trials, and systematic reviews were screened. After an independent screening and full-text review, 10 articles were selected, and an appraisal of risk of bias was performed. RESULTS: From 182 articles screened, 9 randomized controlled trials and 1 nonrandomized controlled trial met the inclusion criteria. Pooled analyses were performed to calculate effect sizes and 95% confidence intervals (CIs). There was a positive effect favoring propranolol use that significantly decreased resting energy expenditure (g = -0.64; 95% CI, -0.8 to -0.5; p < 0.001) and trunk fat (g = -0.3; 95% CI, -0.4 to -0.1; p < 0.001) as well as improved peripheral lean mass (g = 0.45; 95% CI, 0.3-0.6; p < 0.001) and insulin resistance (g = -1.35; 95% CI, -2.0 to -0.6; p < 0.001). Occurrence of adverse events was not significantly different between the treated patients the and controls. CONCLUSION: Limited evidence suggests beneficial effects of propranolol after burn injury, and its use seems safe. However, further trials on adult population with a broader range of outcome measures are warranted. LEVEL OF EVIDENCE: Systematic review and meta-analysis, level III.

ABSTRACT

AIM: A meta-analysis and review of the evidence was conducted to determine the efficacy of aquatic exercise training for individuals with heart failure compared to traditional land-based programmes. METHODS: A systematic search was conducted for studies published prior to March 2014, using MEDLINE, PUBMED, Cochrane Library, CINAHL and PEDro databases. Key words and synonyms relating to aquatic exercise and heart failure comprised the search strategy. Interventions included aquatic exercise or a combination of aquatic plus land-based training, whilst comparator protocols included usual care, no exercise or land-based training alone. The primary outcome of interest was exercise performance. Studies reporting on muscle strength, quality of life and a range of haemodynamic and physiological parameters were also reviewed. RESULTS: Eight studies met criteria, accounting for 156 participants. Meta-analysis identified studies including aquatic exercise to be superior to comparator protocols for 6 minute walk test (p < 0.004) and peak power (p < 0.044). Compared to land-based training programmes, aquatic exercise training provided similar benefits for VO(2peak), muscle strength and quality of life, though was not superior. Cardiac dimensions, left ventricular ejection fraction, cardiac output and BNP were not influenced by aquatic exercise training. CONCLUSIONS: For those with stable heart failure, aquatic exercise training can improve exercise capacity, muscle strength and quality of life similar to land-based training programmes. This form of exercise may provide a safe and effective alternative for those unable to participate in traditional exercise programmes.

ABSTRACT

OBJECTIVE: To investigate the feasibility and safety of a 24-week exercise intervention, compared to control, in males with Barrett's oesophagus, and to estimate the effect of the intervention, compared to control, on risk factors associated with oesophageal adenocarcinoma development. METHODS: A randomized controlled trial of an exercise intervention (60 minutes moderate-intensity aerobic and resistance exercise five days/week over 24 weeks; one supervised and four unsupervised sessions) versus attention control (45 minutes stretching five days/week over 24 weeks; one supervised and four unsupervised sessions) in inactive, overweight/obese (25.0-34.9 kg/m2) males with Barrett's oesophagus, aged 18-70 years. Primary outcomes were obesity-associated hormones relevant to oesophageal adenocarcinoma risk (circulating concentrations of leptin, adiponectin, interleukin-6, tumour necrosis factor-alpha, C-reactive protein, and insulin resistance [HOMA]). Secondary outcomes included waist circumference, body composition, fitness, strength and gastro-oesophageal reflux symptoms. Outcomes were measured at baseline and 24-weeks. Intervention effects were analysed using generalised linear models, adjusting for baseline value. RESULTS: Recruitment was difficult in this population with a total of 33 participants recruited (target sample size: n = 80); 97% retention at 24-weeks. Adherence to the exercise protocol was moderate. No serious adverse events were reported. A statistically significant intervention effect (exercise minus control) was observed for waist circumference (-4.5 [95% CI -7.5, -1.4] cm; p < 0.01). Effects on primary outcomes were not statistically significant. CONCLUSION: This small, exploratory trial provides important information to inform future trial development including recruitment rates and estimates of effect sizes on outcomes related to oesophageal adenocarcinoma risk. Future trials should investigate a combined dietary and exercise intervention to achieve greater weight loss in this population and relax inclusion criteria to maximize recruitment.

ABSTRACT

The aims of this study were to identify the risk factors for developing heterotopic ossification in patients with burns injuries and, second, to review the outcomes associated with the treatment disodium etidronate. Patients with heterotopic ossification were identified using the burns unit computer database. The control group was the patients who were the next admission after admission of the patient who subsequently developed heterotopic ossification. Demographic and clinical data were collected. Univariate and multivariate techniques were used to identify risk factors for heterotopic ossification. We reviewed 337 patients admitted over a 5-year period and identified 19 patients with heterotopic ossification (5.6%). A further 19 burn injury patients were included as controls. Heterotopic ossification developed clinically and radiologically after a median time of 37 days (interquartile range [IQR], 30-40) and 49 days (IQR, 38-118), respectively. In univariate analysis, heterotopic ossification was associated with a greater %TBSA, inhalation injury, use of mechanical ventilation, number of surgical procedures, sepsis, and longer time to active movement. In a multivariate analysis that adjusted for severity of burn injury by means of the Belgian Outcome in Burn Injury score, time to active movement was recognized as an independent risk factor for heterotopic ossification (odds ratio 1.48, 95% confidence interval 1.09-2.01). Elevations in serum calcium concentrations were the only observed adverse effects for disodium etidonrate. This study has demonstrated that %TBSA, inhalation injury, and the need for ventilatory support and the use of multiple surgical procedures are predictive of the development of heterotopic ossification.

ABSTRACT

Controversy remains over appropriate endpoints of resuscitation during fluid resuscitation in early burns management. We reviewed the evidence as to whether utilizing alternative endpoints to hourly urine output produces improved outcomes. MEDLINE, CINAHL, EMBASE, Cochrane Library, Web of Science, and full-text clinicians' health journals at OVID, from 1990 to January 2014, were searched with no language restrictions. The keywords burns AND fluid resuscitation AND monitoring and related synonyms were used. Outcomes of interest included all-cause mortality, organ dysfunction, length of stay (hospital, intensive care), time on mechanical ventilation, and complications such as incidence of pulmonary edema, compartment syndromes, and infection. From 482 screened, eight empirical articles, 11 descriptive studies, and one systematic review met the criteria. Utilization of hemodynamic monitoring compared with hourly urine output as an endpoint to guide resuscitation found an increased survival (risk ratio [RR], 0.58; 95% confidence interval, 0.42-0.85; P < 0.004), with no effect on renal failure (RR, 0.77; 95% confidence interval, 0.39-1.43; P = 0.38). However, inclusion of the randomized controlled trials only found no survival advantage of hemodynamic monitoring over hourly urine output (RR, 0.72; 95% confidence interval, 0.43-1.19; P = 0.19) for mortality. There were conflicting findings between studies for the volume of resuscitation fluid, incidence of sepsis, and length of stay. There is limited evidence of increased benefit with utilization of hemodynamic monitoring, however, all studies lacked assessor blinding. A large multicenter study with a priori-determined subgroup analysis investigating alternative endpoints of resuscitation is warranted.

ABSTRACT

INTRODUCTION: Patients post sepsis syndromes have a poor quality of life and a high rate of recurring illness or mortality. Follow-up clinics have been instituted for patients postgeneral intensive care but evidence is sparse, and there has been no clinic specifically for survivors of sepsis. The aim of this trial is to investigate if targeted screening and appropriate intervention to these patients can result in an improved quality of life (Short Form 36 health survey (SF36V.2)), decreased mortality in the first 12 months, decreased readmission to hospital and/or decreased use of health resources. METHODS AND ANALYSIS: 204 patients postsepsis syndromes will be randomised to one of the two groups. The intervention group will attend an outpatient clinic two monthly for 6 months and receive screening and targeted intervention. The usual care group will remain under the care of their physician. To analyse the results, a baseline comparison will be carried out between each group. Generalised estimating equations will compare the SF36 domain scores between groups and across time points. Mortality will be compared between groups using a Cox proportional hazards (time until death) analysis. Time to first readmission will be compared between groups by a survival analysis. Healthcare costs will be compared between groups using a generalised linear model. Economic (health resource) evaluation will be a within-trial incremental cost utility analysis with a societal perspective. ETHICS AND DISSEMINATION: Ethical approval has been granted by the Royal Brisbane and Women's Hospital Human Research Ethics Committee (HREC; HREC/13/QRBW/17), The University of Queensland HREC (2013000543), Griffith University (RHS/08/14/HREC) and the Australian Government Department of Health (26/2013). The results of this study will be submitted to peer-reviewed intensive care journals and presented at national and international intensive care and/or rehabilitation conferences.

ABSTRACT

OBJECTIVES: Accurate diagnosis of sepsis is difficult in patients post burn due to the large inflammatory response produced by the major insult. We aimed to estimate the values of serum N-terminal pro-B-type natriuretic peptide and procalcitonin and the changes in hemodynamic variables as markers of sepsis in critically ill burn patients. DESIGN: Prospective, observational study. SETTING: A quaternary-level university-affiliated ICU. PATIENTS: Fifty-four patients with burns to total body surface area of greater than or equal to 15%, intubated with no previous cardiovascular comorbidities, were enrolled. INTERVENTIONS: At admission, a FloTrac/Vigileo system was attached and daily blood samples taken from the arterial catheter. Infection surveillance was carried out daily with patients classified as septic/nonseptic according to American Burns Consensus criteria. MEASUREMENTS AND MAIN RESULTS: N-terminal pro-B-type natriuretic peptide, procalcitonin, and waveform analysis of changes in stroke volume index and systemic vascular resistance index were measured within the first 24 hours after burn and daily thereafter for the length of the ICU stay or until their first episode of sepsis. Prevalences of stroke volume variation less than 12% (normovolemia) with hypotension (systolic blood pressure < 90 mm Hg) were recorded. Patients with sepsis differed significantly from "no sepsis" for N-terminal pro-B-type natriuretic peptide, systemic vascular resistance index, and stroke volume index on days 3-7. Procalcitonin did not differ between sepsis and "no sepsis" except for day 3. Area under the receiver operating characteristic curves showed excellent discriminative power for B-type natriuretic peptide (p = 0.001; 95% CI, 0.99-1.00), systemic vascular resistance index (p < 0.001; 95% CI, 0.97-0.99), and stroke volume index (p < 0.01; 95% CI, 0.96-0.99) in predicting sepsis but not for procalcitonin (not significant; 95% CI, 0.29-0.46). A chi-square crosstab found that there was no relationship between hypotension with normovolemia (stroke volume variation < 12%) and sepsis. CONCLUSIONS: Serum N-terminal pro-B-type natriuretic peptide levels and certain hemodynamic changes can be used as an early indicator of sepsis in patients with burn injury. Procalcitonin did not assist in the early diagnosis of sepsis.
