Concordance between coding sources of burn size and depth across Australian and New Zealand specialist burn services.

BACKGROUND: The percentage of total body surface area (%TBSA) burned and burn depth provide valuable information on burn injury severity. OBJECTIVE: This study investigated the concordance between The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) codes and expert burn clinicians in assessing burn injury severity. METHOD: We conducted a retrospective population-based review of all patients who sustained a burn injury between July 1, 2009, and June 30, 2019, requiring admission into a specialist burn service across Australia and New Zealand. The %TBSA burned (including the percentage of full thickness burns) recorded by expert burn clinicians within the Burns Registry of Australia and New Zealand (BRANZ) were compared to ICD-10-AM coding. RESULTS: 20,642 cases (71.5%) with ICD-10-AM code data were recorded. Overall, kappa scores (95% confidence interval [CI]) for burn size ranged from 0.64 (95% CI 0.63-0.66) to 0.86 (95% CI 0.78-0.94) indicating substantial to almost perfect agreement across all %TBSA groups. When stratified by depth, the lowest agreement was observed for < 10% TBSA and < 10% full thickness (kappa 0.03; 95% CI 0.02-0.04) and the highest agreement was observed for burns of ≥ 90% TBSA and ≥ 90% full thickness (kappa 0.72; 95% CI 0.58-0.85). CONCLUSION: Overall, there was substantial agreement between the BRANZ and ICD-10-AM coded data for %TBSA classification. When %TBSA classification was stratified by burn depth, greater agreement was observed for larger and deeper burns compared with smaller and superficial burns. IMPLICATIONS: Greater consistency in the classification of burns is needed.

Comparing Peak Burn Injury Times and Characteristics in Australia and New Zealand.

Burns are a leading cause of morbidity and mortality worldwide. Understanding when and how burns occur, as well as the differences between countries, would aid prevention efforts. A review of burn injuries occurring between July 2009 and June 2021 was undertaken using data from the Burns Registry of Australia and New Zealand. Peak injury times were identified on a country-by-country basis. Variations in demographic and injury event profiles between countries were compared using descriptive statistics. There were 26,925 admissions recorded across the two countries (23,323 for Australia; 3602 for New Zealand). The greatest number of injuries occurred between 6 PM to 7 PM in Australia (1871, 8.0%) and between 5 PM to 6 PM in New Zealand (280, 7.8%). In both countries, scalds accounted for the greatest proportion of injuries during peak times (988, 45.8%), but a greater proportion of young children (under three years) sustained burns during New Zealand's peak times. The number of burn injuries associated with the preparation and/or consumption of food offers an opportunity for a targeted prevention program that may yield benefits across the two countries. Age- and mechanism-related differences in the profile of burn-injured patients need to be considered when developing and implementing such a program.

Taking the VITALS to Interrupt Microaggressions.

INTRODUCTION: Microaggressions are subtle statements or actions that reinforce stereotypes. Medical students, residents, and faculty report experiences of microaggressions, with higher incidences among women and marginalized groups. An educational tool utilizing the acronym VITALS (validate, inquire, take time, assume, leave opportunities, speak up) provided a framework for processing and addressing microaggressions encountered in the academic health center environment. METHODS: We developed a 60-minute workshop designed to raise awareness of microaggressions encountered by medical students and trainees. The workshop consisted of a didactic presentation and multiple interactive exercises shared in small- and large-group formats. Participants also completed pre- and postsurvey instruments to assess changes in their knowledge and attitudes about promoting an environment that prevents microaggressions from occurring. RESULTS: There were 176 participants who completed our workshop. In comparing anonymized pre- and postworkshop responses submitted by attendees, an increase in recognition of one's own potential stereotypical beliefs about social identity groups was observed. Participants also expressed a greater sense of empowerment to foster mutual respect in health care settings. After completing the workshop, attendees indicated a greater likelihood to engage in difficult conversations, including responding to microaggressions, which both peers and superiors encountered in both academic and clinical environments. DISCUSSION: The workshop provided an interactive format for medical students and trainees to gain awareness, knowledge, and tools for addressing microaggressions encountered in health care settings.

Variation in burn wound management approaches for paediatric burn patients in Australia and New Zealand.

BACKGROUND: To date, no large-scale exploration of the profile of, and variance among paediatric patients who underwent a burn wound management procedure in theatre exists in an Australian and New Zealand context. This study aims to provide a profile of paediatric burn patients who underwent a burn wound management procedure in theatre during an acute admission and highlight specific areas of practice where there is variation between burn services that may affect treatment efficacy and efficiency. METHODS: We performed a retrospective review of all paediatric patients (ages <16 years) who sustained a burn injury between July 2016 and June 2019 and underwent a burn wound management procedure in theatre, using data from the Burns Registry Australia New Zealand. RESULTS: The number of patients across burn services decreased as TBSA increased. Deep dermal burns represented the majority of cases across services. There was significant variation in time from injury to admission and the proportion of patients who received skin grafts across services. CONCLUSIONS: Significant differences in the patient profile and clinical practices were observed among burn services. A greater understanding of the factors underlying the variations at each particular service will also be helpful.

Subjective experiences of bicyclists being passed by motor vehicles: The relationship to motor vehicle passing distance.

BACKGROUND: Feeling unsafe when riding a bicycle is a key barrier to cycling participation. To better understand the experiences of cycling on-road, this study aimed to explore the relationship between cyclists' subjective experiences and the lateral passing distance of motor vehicles. METHODS: An on-road observational study was conducted in Victoria, Australia. Participants had a custom device installed on their bicycle that measured the lateral passing distance of motor vehicles and included a handlebar mounted "panic button" that participants could press when they felt that a passing event was too close or unsafe. A random effects logistic regression model was used to investigate the relationship between cyclist sex, motor vehicle type and infrastructure characteristics, and button press events. RESULTS: A total of 217 button press events were recorded (1.2 % of all passing events) from 60 participants. For events with a passing distance closer than 100 cm, 10.4 % of these events had a recorded button press. The adjusted odds of a button press event were over three-fold higher when the rider was passed by a truck, compared to when the rider was passed by a sedan. The predicted probability of a button press event was higher in events occurring in road environments with no bike lane and no parked cars (1.9 %) compared to no bike lane with parked cars (1.2 %), a bike lane with no parked cars (0.9 %) and a bike lane with parked cars (0.7 %). CONCLUSIONS: The study identified important links between cyclists' subjective experience of unsafe events, motor vehicle types and infrastructure characteristics. Greater emphasis needs to be placed on capturing subjective experiences to inform and advance the development and implementation of safe and comfortable cycling infrastructure.

Identify the key characteristics of pedestrian collisions through in-depth interviews: a pilot study.

This study aimed to assess the feasibility of recruiting injured pedestrians from the emergency department of a major trauma centre, using an in-depth interview shortly post collision. Convenience sampling was used to prospectively recruit injured pedestrians from the Alfred Hospital Emergency and Trauma Centre. Of the 102 injured pedestrians, 39 met eligibility criteria and of these, 30 (77%) consented and completed the questionnaire. Over half of the collisions occurred at an intersection (57%), and of these the most common pre-impact vehicle manoeuvre was a vehicle turning into the street the pedestrian was crossing. In-depth interview during the early post-crash period was a feasible and effective method of collecting detailed data in an accessible sample. However, only 38% of patients met eligibility criteria. To enhance representativeness, supplementing interview data with police-reported crash data, recruiting from hospital wards and crash location assessment is recommended.

The prevalence of alcohol and other drugs in fatal road crashes in Victoria, Australia.

BACKGROUND: Driving under the influence of drugs, including alcohol, is a globally recognised risk factor for road traffic crashes. While the prevalence of alcohol and other drugs in fatal road crashes has been examined in other countries, recent data investigating drug driving in fatal Australian crashes are limited. This study aimed to examine how the presence of alcohol and other drugs in fatal road trauma in Victoria has changed over time in different road users. METHODS: A population-based review of road trauma deaths was performed over the period of 01 July 2006 to 30 June 2016 in Victoria, Australia, using data from the National Coronial Information System (NCIS) and the Victorian State Trauma Registry (VSTR). Drugs were grouped according to type and analysed accordingly. Poisson regression models were used to determine change in incidence rates over the study period. RESULTS: There were 2287 road traffic fatalities with complete toxicology data (97% of all road traffic fatalities). Alcohol (blood alcohol concentration, BAC) was the most commonly detected drug (>0.001 g/100 mL: 21.1%; >0.05 g/100 mL: 18.4%), followed by opioids (17.3%), THC (13.1%), antidepressants (9.7%), benzodiazepines (8.8%), amphetamine-type stimulants (7.1%), ketamine (3.4%), antipsychotics (0.9%) and cocaine (0.2%). Trends demonstrated changing use over time with specific drugs. Alcohol positive road fatalities declined 9% per year in passenger car/4WD drivers (IRR = 0.91, 95% CI: 0.88-0.95). The incidence of strong opioids (oxycodone, fentanyl, morphine, and methadone) increased 6% per year (IRR = 1.06; 95% CI: 1.02-1.10). Methylamphetamine was detected in 6.6% of cases and showed a yearly increase of 7% (IRR = 1.07; 95% CI: 1.01-1.13). The incidence of THC remained unchanged over the period, observed in 13.1% of cases. Stronger opioids were more commonly detected among pedal cyclists (19.0%) and pedestrians (20.9%) while THC was more commonly detected among motorcyclists (19.8%) and other light vehicle drivers (17.6%). CONCLUSIONS: A decline in the prevalence of alcohol in fatalities suggests that law enforcement and public health strategies in Australia to address road fatalities and drink-driving may have had a positive effect. However, increases were observed in the incidence of other potentially impairing drugs including opioids and amphetamines, specifically methylamphetamine, indicating a concerning trend in road safety in Victoria that warrants further monitoring.

Association between gender and outcomes of acute burns patients.

BACKGROUND: Burn injuries are a complex and serious public health concern. Where the total body surface area of the burn exceeds 50%, mortality rates as high as 48% have been reported. While the association between gender and burn injury outcomes has been explored, findings are inconsistent. METHODS: Adult patients (>15 years) admitted between 1 July 2009 and 30 June 2018 to intensive care units of burn centres that provide specialist burn care in Australia and New Zealand were included. Raw mortality rates were examined and a multivariable Cox proportional hazards regression was used to investigate the association between gender and time to in-hospital death. RESULTS: There were 2227 eligible burn injury admissions. Men comprised the majority (77.6%). The proportion of women who died in hospital was greater than men and the adjusted odds of in-hospital mortality were 34% lower in men (odds ratio 0.66; 95% confidence interval (CI) 0.45-0.98). The unadjusted rate of in-hospital mortality for men was 44% lower than women (hazard ratio 0.56; 95% CI 0.41-0.76). After adjusting for confounders, there was no association between gender and survival time (hazard ratio 0.76; 95% CI 0.54-1.06). CONCLUSION: After adjustment for key differences in case-mix between men and women, there was an association between gender and in-hospital mortality and no association between gender and time to death. Our findings indicate that the worse outcomes observed for women are associated with different age and patterns of injury, and provide further information to direct and inform targeted prevention measures for vulnerable populations.

How much space do drivers provide when passing cyclists? Understanding the impact of motor vehicle and infrastructure characteristics on passing distance.

BACKGROUND: Understanding factors that influence the distance that drivers provide when passing cyclists is critical to reducing subjective risk and improving cycling participation. This study aimed to quantify passing distance and assess the impact of motor vehicle and road infrastructure characteristics on passing distance. METHODS: An on-road observational study was conducted in Victoria, Australia. Participants had a custom device installed on their bicycle and rode as per their usual cycling for one to two weeks. A hierarchical linear model was used to investigate the relationship between motor vehicle and infrastructure characteristics (location, presence of on-road marked bicycle lane and the presence of parked cars on the kerbside) and passing distance (defined as the lateral distance between the end of the bicycle handlebars and the passing motor vehicle). RESULTS: Sixty cyclists recorded 18,527 passing events over 422 trips. The median passing distance was 173 cm (Q1: 137 cm, Q3: 224 cm) and 1085 (5.9%) passing events were less than 100 cm. Relative to sedans, 4WDs had a reduced mean passing distance of 15 cm (Q1: 12 cm, Q3: 17 cm) and buses had a reduced mean passing distance of 28 cm (Q1: 16 cm, Q3: 40 cm). Relative to passing events that occurred on roads without a marked bicycle lane and without parked cars, passing events on roads with a bike lane with no parked cars had a reduced mean passing distance of 27 cm (Q1: 25 cm, Q3: 29 cm), and passing events on roads with a bike lane and parked cars had a mean lower passing distance of 40 cm (Q1: 37 cm, Q3: 43 cm). CONCLUSIONS: One in every 17 passing events was a close (<100 cm) passing event. We identified that on-road bicycle lanes and parked cars reduced passing distance. These data can be used to inform the selection and design of cycling-related infrastructure and road use with the aim of improving safety for cyclists.

A pain in the bud? Implications of cross-modal sensitivity for pain experience.

There is growing evidence that enhanced sensitivity to painful clinical procedures and chronic pain are related to greater sensitivity to other sensory inputs, such as bitter taste. We examined cross-modal sensitivities in two studies. Study 1 assessed associations between bitter taste sensitivity, pain tolerance, and fear of pain in 48 healthy young adults. Participants were classified as non-tasters, tasters and super-tasters using a bitter taste test (6-n-propythiouracil; PROP). The latter group had significantly higher fear of pain (Fear of Pain Questionnaire) than tasters (p=.036, effect size r = .48). There was only a trend for an association between bitter taste intensity ratings and intensity of pain at the point of pain tolerance in a cold pressor test (p=.04). In Study 2, 40 healthy young adults completed the Adolescent/Adult Sensory Profile before rating intensity and unpleasantness of innocuous (33 °C), moderate (41 °C), and high intensity (44 °C) thermal pain stimulations. The sensory-sensitivity subscale was positively correlated with both intensity and unpleasantness ratings. Canonical correlation showed that only sensitivity to audition and touch (not taste/smell) were associated with intensity of moderate and high (not innocuous) thermal stimuli. Together these findings suggest that there are cross-modal associations predominantly between sensitivity to exteroceptive inputs (i.e., taste, touch, sound) and the affective dimensions of pain, including noxious heat and intolerable cold pain, in healthy adults. These cross-modal sensitivities may arise due to greater psychological aversion to salient sensations, or from shared neural circuitry for processing disparate sensory modalities.

Changing physician incentives for affordable, quality cancer care: results of an episode payment model.

PURPOSE: This study tested the combination of an episode payment coupled with actionable use and quality data as an incentive to improve quality and reduce costs. METHODS: Medical oncologists were paid a single fee, in lieu of any drug margin, to treat their patients. Chemotherapy medications were reimbursed at the average sales price, a proxy for actual cost. RESULTS: Five volunteer medical groups were compared with a large national payer registry of fee-for-service patients with cancer to examine the difference in cost before and after the initiation of the payment change. Between October 2009 and December 2012, the five groups treated 810 patients with breast, colon, and lung cancer using the episode payments. The registry-predicted fee-for-service cost of the episodes cohort was $98,121,388, but the actual cost was $64,760,116. The predicted cost of chemotherapy drugs was $7,519,504, but the actual cost was $20,979,417. There was no difference between the groups on multiple quality measures. CONCLUSION: Modifying the current fee-for-service payment system for cancer therapy with feedback data and financial incentives that reward outcomes and cost efficiency resulted in a significant total cost reduction. Eliminating existing financial chemotherapy drug incentives paradoxically increased the use of chemotherapy.

Unsupported off-label chemotherapy in metastatic colon cancer.

BACKGROUND: Newer systemic therapies have the potential to decrease morbidity and mortality from metastatic colorectal cancer, yet such therapies are costly and have side effects. Little is known about their non-evidence-based use. METHODS: We conducted a retrospective cohort study using commercial insurance claims from UnitedHealthcare, and identified incident cases of metastatic colon cancer (mCC) from July 2007 through April 2010. We evaluated the use of three regimens with recommendations against their use in the National Comprehensive Cancer Center Network Guidelines, a commonly used standard of care: 1) bevacizumab beyond progression; 2) single agent capecitabine as a salvage therapy after failure on a fluoropyridimidine-containing regimen; 3) panitumumab or cetuximab after progression on a prior epidermal growth factor receptor antibody. We performed sensitivity analyses of key assumptions regarding cohort selection. Costs from a payer perspective were estimated using the average sales price for the entire duration and based on the number of claims. RESULTS: A total of 7642 patients with incident colon cancer were identified, of which 1041 (14%) had mCC. Of those, 139 (13%) potentially received at least one of the three unsupported off-label (UOL) therapies; capecitabine was administered to 121 patients and 49 (40%) likely received it outside of clinical guidelines, at an estimated cost of $718,000 for 218 claims. Thirty-eight patients received panitumumab and six patients (16%) received it after being on cetuximab at least two months, at an estimated cost of $69,500 for 19 claims. Bevacizumab was administered to 884 patients. Of those, 90 (10%) patients received it outside of clinical guidelines, at an estimated costs of $1.34 million for 636 claims. CONCLUSIONS: In a large privately insured mCC cohort, a substantial number of patients potentially received UOL treatment. The economic costs and treatment toxicities of these therapies warrant increased efforts to stem their use in settings lacking sufficient scientific evidence.

The transition to electronic documentation on a teaching hospital medical service.

The transition to electronic medical records (EMRs) often includes the transition from paper to electronic documentation, a topic less well described in the literature than other aspects of EMR adoption. As part of a broader EMR project, we have participated in the transition to electronic notes on the Medicine service of a teaching hospital affiliated with the University of Washington. During a one year period beginning in February 2005 we adopted the use of semi-structured documentation templates permitting both encoded and narrative text components for admission, progress, and procedure notes, and for some discharge summaries. Currently over 1400 notes are entered each week. Fifty eight percent are entered by residents, 20% by attending physicians, and the remainder by other trainees and staff. The period of greatest change from paper to electronic notes occurred (by design) during the late spring and summer. Leadership, application functionality, speed, note writing time requirements, data availability, training needs, and other factors influenced adoption of this important part of our EMR.
