Grip and muscle strength dynamometry in acute burn injury: Evaluation of an updated assessment protocol
External stabilization is reported to improve reliability of hand held dynamometry, yet this has not been tested in burns. We aimed to assess the reliability of dynamometry using an external system of stabilization in people with moderate burn injury and explore construct validity of strength assessment using dynamometry.
Participants were assessed on muscle and grip strength three times on each side. Assessment occurred three times per week for up to four weeks. Within session reliability was assessed using intraclass correlations calculated for within session data grouped prior to surgery, immediately after surgery and in the sub-acute phase of injury. Minimum detectable differences were also calculated. In the same timeframe categories, construct validity was explored using regression analysis incorporating burn severity and demographic characteristics.
Thirty-eight participants with total burn surface area 5 â 40% were recruited. Reliability was determined to be clinically applicable for the assessment method (intraclass correlation coefficient \u3e0.75) at all phases after injury. Muscle strength was associated with sex and burn location during injury and wound healing. Burn size in the immediate period after surgery and age in the sub-acute phase of injury were also associated with muscle strength assessment results.
Hand held dynamometry is a reliable assessment tool for evaluating within session muscle strength in the acute and sub-acute phase of injury in burns up to 40% total burn surface area. External stabilization may assist to eliminate reliability issues related to patient and assessor strength
Increased burn healing time is associated with higher Vancouver Scar Scale score
Increased burn wound healing time has been shown to influence abnormal scarring. This study hypothesized that scar severity increases commensurate to the increase in time to healing (TTH) of the wound. Wound healing and scar data from burn patients treated by the Burn Service of Western Australia at Royal Perth Hospital were examined. The relationship between TTH and scar severity, as assessed by the modified Vancouver Scar Scale (mVSS), was modelled using regression analysis. Interaction terms evaluated the effect of surgery and total body surface area â burn (TBSA) on the main relationship. Maximum likelihood estimation was used to account for potential bias from missing independent variable data. The sample had a median age of 34 years, TTH of 24 days, TBSA of 3% and length of stay of five days, 70% were men and 71% had burn surgery. For each additional day of TTH, the mVSS score increased by 0.11 points (P ⊽ 0.001) per day in the first 21 days and 0.02 points per day thereafter (P = 0.004). The relationship remained stable in spite of TBSA or surgical intervention. Investigation of the effect of missing data revealed the primary model underestimated the strength of the association. An increase in TTH within 21 days of injury is associated with an increase in mVSS or reduced scar quality. The results confirm that efforts should be directed toward healing burn wounds as early as possible
Coproduction and health: Public and clinicians' perceptions of the barriers and facilitators
Background
Coproduction is an approach increasingly recognized across public services internationally. However, awareness of the term and the barriers and facilitators to its implementation in the NHS are not widely understood. This study examines clinician and public perceptions of coproduction within the context of the Prudent Healthcare initiative.
Objectives
To provide insights into how coproduction is viewed by clinicians and the public and identify perceived barriers and facilitators to its implementation.
Design
Using qualitative research methods, interviews were conducted with the public (n = 40) and clinicians (n = 40). Five focus groups were also conducted with the public (n = 45) and six focus groups with clinicians (n = 26). The COMâB model was used to analyse the data; key domains include Capability, Opportunity and Motivation.
Setting
This is an allâWales study, involving six Health Boards, an NHS trust and community and patient groups.
Results
Key barriers relating to Capability include lack of awareness of the term coproduction and inadequate communication between clinicians and citizens. Opportunityâcentred barriers include service and time constraints. Conversely, facilitators included utilizing partnerships with community organizations. Motivationârelated barriers included preconceptions about patientsâ limitations to coproduce.
Conclusions
There were broadly positive perceptions among participants regarding coproduction, despite initial unfamiliarity with the term. Despite study limitations including underrepresentation of employed public participants and junior doctors, our analysis may assist researchers and policymakers who are designing, implementing and evaluating interventions to promote coproduction
Increased risk of blood transfusion in patients with diabetes mellitus sustaining non-major burn injury
Background: Due to the increased mortality and morbidity associated with blood transfusion, identifying modifiable predictors of transfusion are vital to prevent or minimise blood use. We hypothesised that burn patients with diabetes mellitus were more likely to be prescribed a transfusion. These patients tend to have increased age, number of comorbidities, infection risk and need for surgery which are all factors reported previously to be associated with blood use.
Objective: To determine whether patients with diabetes mellitus who have sustained a burn â¤20% total body surface area (TBSA) are at higher risk of receiving red blood cell transfusion compared to those without diabetes mellitus.
Method: This was a retrospective cohort study including patients admitted to the major Burns Unit in Western Australia for management of a burn injury. Only the first hospital admission between May 2008 to February 2017 were included.
Results: Among 2,101 patients with burn injuries â¤20% TBSA, 48 (2.3%) received packed red blood cells and 169 (8.0%) had diabetes. There were 13 (7.7%) diabetic patients that were transfused versus 35 (1.8%) non-diabetic patients. Patients with diabetes were 5.2 (p=0.034) times more likely to receive packed red blood cells after adjusting for percentage TBSA, haemoglobin at admission or prior to transfusion, number of surgeries, total comorbid burden and incidence of infection. As percentage TBSA increases, the probability of packed red blood cell transfusion increases at a higher rate in DM patients.
Conclusions: This study showed that diabetic patients with burn injuries â¤20% TBSA have a higher probability of receiving packed red blood cell transfusion compared to patients without diabetes. This effect was compounded in burns with higher percentage TBSA
Grip and Muscle Strength Dynamometry Are Reliable and Valid in Patients With Unhealed Minor Burn Wounds
Small burns are common and can cause disproportionate levels of disability. The ability to measure muscle impairment and consequent functional disability is a necessity during rehabilitation of patients. This study aimed to determine the reliability and validity of grip and muscle strength dynamometry in patients with unhealed, minor burn wounds. Grip and muscle strength were assessed three times on each side. Assessment occurred at presentation for the initial injury and again every other day (or every 5 days beyond 10 days post injury) until discharge from the service. Reliability was assessed using intraclass correlation. Minimum detectable differences were calculated for each muscle group. Validity was assessed using regression analysis, incorporating appropriate burn severity measures and patient demographics. Thirty patients with TBSA 515% were assessed. Both grip and muscle strength demonstrated very good reliability (intraclass correlation coefficient: 0.85-0.96). Minimum detectable differences ranged from 3.8 to 8.0 kg. Validity of both forms of dynamometry was confirmed through associations with gender for all muscle groups (
The Short- and Long-Term Outcome Priorities of a Western Australian Adult Burn Population
To optimize patient recovery, understanding which outcomes are most important to burn patients is key. However, research to determine what outcomes are patient priorities is limited. Therefore, we assessed what outcomes are most important to Western Australian burn patients, separately in the short-term (<6 months) and long-term (6-24 months) after injury. Adult patients who had a burn injury 3-36 months ago completed a survey, rating the importance of 36 short- and long-term outcomes. The survey items were ranked according to the number of patients reporting the outcome as "very important."Results were compared between subgroups based on age, gender, burn size, and number of surgeries. Ninety-three patients were included. In the short-term, "not having a wound infection"(87.1%), "good wound healing"(83.9%), and "walking or moving around"(74.7%) were the most important outcomes. "Lifting or moving something"(67.6%), "walking or moving around"(66.2%), and "being independent"(66.2%) were reported as most important in the long-term. Scar-related outcomes were more important to females and to patients with multiple surgeries; mental health outcomes were priorities for females and patients with major burns; walking and moving around to males and older patients; and social and financial outcomes were rated highly by patients with major burns and multiple surgeries. In conclusion, the most important outcomes were consistent across time periods, indicating the importance of core outcomes in longitudinal follow-up. The wide range of priority outcomes and differences between subgroups underlines the need for multidisciplinary care and a patient-centered approach to support patients.</p
Improved and standardized method for assessing years lived with disability after burns and its application to estimate the non-fatal burden of disease of burn injuries in Australia, New Zealand and the Netherlands
Background:
Burden of disease estimates are an important resource in public health. Currently, robust estimates are not available for the burn population. Our objectives are to adapt a refined methodology (INTEGRIS method) to burns and to apply this new INTEGRIS-burns method to estimate, and compare, the burden of disease of burn injuries in Australia, New Zealand and the Netherlands.
Methods:
Existing European and Western-Australian health-related quality of life (HRQL) datasets were combined to derive disability weights for three homogenous burn injury groups based on percentage total body surface area (%TBSA) burned. Subsequently, incidence data from Australia, New Zealand, and the Netherlands from 2010 to 2017 were used to compute annual non-fatal burden of disease estimates for each of these three countries. Non-fatal burden of disease was measured by years lived with disability (YLD).
Results:
The combined dataset included 7159 HRQL (EQ-5D-3âL) outcomes from 3401 patients. Disability weights ranged from 0.046 (subgroup â24âmonths post-burn) to 0.497 (subgroup >â20% TBSA burned 0â1âmonths post-burn). In 2017 the non-fatal burden of disease of burns for the three countries (YLDs/100,000 inhabitants) was 281 for Australia, 279 for New Zealand and 133 for the Netherlands.
Conclusions:
This project established a method for more precise estimates of the YLDs of burns, as it is the only method adapted to the nature of burn injuries and their recovery. Compared to previous used methods, the INTEGRIS-burns method includes improved disability weights based on severity categorization of burn patients; a better substantiated proportion of patients with lifelong disability based; and, the application of burn specific recovery timeframes. Information derived from the adapted method can be used as input for health decision making at both the national and international level. Future studies should investigate whether the application is valid in low- and middle- income countries
The efficacy of resistance training in addition to usual care for adults with acute burn injury: A randomised controlled trial
Resistance training immediately after a burn injury has not been investigated previously. This randomised, controlled trial assessed the impact of resistance training on quality of life plus a number of physical, functional and safety outcomes in adults with a burn injury. Patients were randomly assigned to receive, in addition to standard physiotherapy, four weeks of high intensity resistance training (RTG) or sham resistance training (CG) three days per week, commenced within 72h of the burn injury. Outcome data was collected at six weeks, three and six months after burn injury. Quality of life at 6 months was the primary endpoint. Data analysis was an available cases analysis with no data imputed. Regression analyses were used for all longitudinal outcome data and between-group comparisons were used for descriptive analyses. Forty-eight patients were randomised resistance training (RTG) (n=23) or control group (CG) (n=25). The RTG demonstrated improved outcomes for the functional domain of the Burn Specific Health Scale-Brief (p=0.017) and the Quick Disability of Arm Shoulder and Hand (pp=0.001). Total quality of life scores, lower limb disability, muscle strength and volume were not seen to be different between groups (p\u3e0.05). Resistance training in addition to usual rehabilitation therapy showed evidence of improving functional outcomes, particularly in upper limb burn injuries. Additionally, resistance training commenced acutely after a burn injury was not seen to be harmful to patients.

Learning a novel technique to identify possible melanomas: are Australian general practitioners better than their U.K. colleagues?
Abstract Background Spectrophotometric intracutaneous analysis (SIAscopyâ˘) is a multispectral imaging technique that is used to identify 'suspicious' (i.e. potentially malignant) pigmented skin lesions for further investigation. The MoleMate⢠system is a hand-held scanner that captures SIAscopy⢠images that are then classified by the clinician using a computerized diagnostic algorithm designed for the primary health care setting. The objectives of this study were to test the effectiveness of a computer program designed to train health care workers to identify the diagnostic features of SIAscopy⢠images and compare the results of a group of Australian and a group of English general practitioners (GPs). Methods Thirty GPs recruited from the Perth (Western Australia) metropolitan area completed the training program at a workshop held in March 2008. The accuracy and speed of their pre- and post-test scores were then compared with those of a group of 18 GPs (including 10 GP registrars) who completed a similar program at two workshops held in Cambridge (U.K.) in March and April, 2007. Results The median test score of the Australian GPs improved from 79.5% to 86.5% (median increase 5.5%; p < 0.001) while the median test score of the English GPs improved from 74.5% to 86.5% (median increase 9.5%; p < 0.001). The Australian GPs had significantly higher pre-test scores but there were no significant differences in post-test scores between the Australian and English GPs or between the GPs and GP registrars. There was no significant difference in scores between GPs with previous dermoscopy experience or dermatology training. Conclusion Most of the SIAscopy⢠features can be learnt to a reasonable degree of accuracy with this brief computer training program. Although the Australian GPs scored higher in the pre-test, both groups had similar levels of accuracy and speed in interpreting the SIAscopy⢠features after completing the program. Scores were not affected by previous dermoscopy experience or dermatology training, which suggests that the MoleMate⢠system is relatively easy to learn
"You are just left to get on with it": qualitative study of patient and carer experiences of the transition to secondary progressive multiple sclerosis
Objectives Although the transition to secondary progressive multiple sclerosis (SPMS) is known to be a period of uncertainty for clinicians, who may find progressive disease challenging to objectively identify, little research has explored the experiences of patients and carers specifically during this transition period. Our objective was to explore what patients and their carers understand about their disease stage and describe their experiences and perspectives on the transition to SPMS.
Design Semistructured qualitative interviews and subsequent validation focus groups were analysed using inductive thematic analysis.
Setting South East Wales, UK.
Participants 20 patients with MS and 13 carers were interviewed. Eight patients and two carers participated in focus groups.
Results Four main themes around disease progression were identified. âRealisationâ describes how patients came to understand they had SPMS while âreactionâ describes their response to this realisation. The ârealitiesâ of living with SPMS, including dealing with the healthcare system during this period, were described along with âfuture challengesâ envisaged by patients and carers.
Conclusions Awareness that the transition to SPMS has occurred, and subsequent emotional reactions and coping strategies, varied widely between patients and their carers. The process of diagnosing the transition was often not transparent and some individuals wanted information to help them understand what the transition to SPMS meant for them
