Missing cases of injury death: use of quantitative methods and case reviews to inform future improvements in case definition

BackgroundKnowledge of fatal injuries is required to inform prevention activities. Where hospital patients with an injury principal diagnosis (PDx) died and were certified to a medical underlying cause of death (UCoD), there is the potential to underestimate injury mortality. We sought to characterise injury/non-injury (NI) mismatches between PDx and UCoD by identifying which subgroups had small/large mismatches, and to understand why mismatches had occurred using informative examples.MethodHospital records (n=10 234) with a PDx of injury were linked to the mortality collection using a unique personal identifier. Percentages UCoD coded to a NI were tabulated, for three follow-up periods and by selected variables. Additionally, we reviewed a sample of 70 records for which there was a mismatch.Results%NIs were 39%, 66% and 77% for time from injury to death of <1 week, <90 days and <1 year, respectively. Variations in %NI were found for all variables. Illustrative examples of 70 medical UCoD deaths showed that for 12 cases the injury event was unequivocally judged to have resulted in premature death. A further 16 were judged as injury deaths using balance of probability arguments.ConclusionThere is variation in rates of mismatch between PDx of injury and UCoD of NI. While legitimate reasons exist for mismatches in certain groups, a material number of injury deaths are not captured using UCoD alone; a new operational definition of injury death is needed. Early solutions are proposed. Further work is needed to investigate operational definitions with acceptable false positive and negative detection rates.

Cognitions That Support Concussion Reporting in Collegiate Athletes: An Analysis of a Worksheet Activity

Background Sports related concussions continue to be a public health concern and improving reporting behavior a focus of educational programs. While educational programs have addressed changes in knowledge of concussion symptoms, it has been challenging to design educational programs which have lasting effects on reporting behavior. Aims The current analysis describes an intervention in which thoughts about reporting behavior are actively written down in a worksheet exercise to “pre-arm” athletes with cognitions designed to enhance reporting behavior prior to the injury event. Method A total of 503 male and female college athletes participating in collision (football, field hockey, ice hockey, lacrosse, and soccer) and contact sports (baseball, basketball, and softball) from 7 colleges/universities competing across all three NCAA divisions provided data collected during a randomized trial of a peer concussion education program. Results Qualitative analysis revealed 10 themes that would improve reporting including short-term benefits, faster recover, safe and healthy return to play, reporting helps the team, reporting protects the brain, risk aversion, long-term benefits, coach will be supportive, teammates will be supportive and understanding, and academic performance will be affected. Discussion Athletes had awareness of key risks involved in concussions and understood both short- and long-term consequences. Conclusion These findings have important implications for understanding how to change athletes’ thoughts about reporting concussions.

Violence by Burning Against Women and Girls: An Integrative Review

Violence against women and girls by burning is a serious and confronting form of gender-based violence. Often, perpetrators aim to disfigure their victims or cause great pain, rather than kill them. Little is known about the characteristics of females who are subjected to violence by burning. This study aimed to review the literature concerning the prevalence, demographic profile, injury event, contributing factors and health outcomes for women and girls who have experienced burn-related violence. A search across five databases (PubMed, CINAHL, PsycINFO, Scopus and LILACS) was conducted up to April 2021 to identify original peer-review research, with a focus on violence by burning against women and girls. The review was guided by the five-stage approach to integrative reviews developed by Whittemore and Knafl (2005) . Fifteen studies were identified. Victims were predominantly married, with low socio-economic status, limited education, and high emotional and financial dependency on their partners or families. Burn injuries were mostly caused by flame or acid, with significant morbidity or high mortality. Motives included family/marital issues or property/financial disputes. This review identified the limited evidence available in the peer-reviewed literature related to burn-related violence against women and girls worldwide. Findings suggest the need for further research to provide a clearer understanding of the complex issues involved.

Development and Evaluation of a Community Surveillance Method for Estimating Deaths Due to Injuries in Rural Nepal

Almost 10% of global deaths are secondary to injuries, yet in the absence of routine injury surveillance and with few studies of injury mortality, the number and cause of injury deaths in many countries are not well understood. This study aimed to develop and evaluate the feasibility of a method to identify injury deaths in rural Nepal. Working with local government authorities, health post staff and female community health volunteers (FCHVs), we developed a two-stage community fatal injury surveillance approach. In stage one, all deaths from any cause were identified. In stage two, an interview with a relative or friend gathered information about the deceased and the injury event. The feasibility of the method was evaluated prospectively between February 2019 and January 2020 in two rural communities in Makwanpur district. The data collection tools were developed and evaluated with 108 FCHVs, 23 health post staff and two data collectors. Of 457 deaths notified over one year, 67 (14.7%) fatal injury events were identified, and interviews completed. Our method suggests that it is feasible to collect data on trauma-related deaths from rural areas in Nepal. These data may allow the development of injury prevention interventions and policy.

Influence of Recovery Treatments on Dicamba-injured Soybean

Non-dicamba resistant soybean yield loss resulting from dicamba off-target injury has become an increasing concern for soybean growers in recent years. After off-target dicamba movement occurs onto sensitive soybean, little information is available on tactics that could be used to mitigate the cosmetic or yield losses that may occur. Therefore, a field experiment was conducted in 2017, 2018, and 2019 to determine if certain recovery treatments of fungicide, plant growth hormone, macro- and micronutrient fertilizer combinations, or weekly irrigation could reduce dicamba injury and/or result in similar yield to soybean that was not injured with dicamba. Simulated drift events of dicamba (5.6 g ae ha−1) were applied to non-dicamba resistant soybean once they reached the V3 or R2 stages of growth. Recovery treatments were applied approximately 14 d after the simulated drift event. Weekly irrigation was the only recovery treatment that provided appreciable levels of injury reduction or increases in soybean height or yield compared to the dicamba-injured plants. Weekly irrigation following the R2 dicamba injury event resulted in an 1% to 14% increase in soybean yield compared to the dicamba-injured control. All other recovery treatments resulted in soybean yields similar to the dicamba-injured control, and similar to or lower than the non-treated control. Results from this study indicate that if soybean have become injured with dicamba, weekly irrigation will help soybean recover some of the yield loss and reduce injury symptoms that resulted from off-target dicamba movement, especially in a year with below average precipitation. However, yield loss will likely not be restored to that of non-injured soybean.

The Effect of Mannitol Addition on Hydration in Acute Kidney Injury Event After High Dose Cisplatin Chemotherapy: An Ambispective Cohort Study

Background: Saline hydration with addition of mannitol have commonly being strategy to avoid cisplatin induced acute kidney injury. While the initial reports demonstrated that mannitol diuresis decreased cisplatin induced renal injury, others have shown renal injury to be worsened.Objective: To compare the risk of acute kidney injury in cancer patients receiving high dose cisplatin with addition and without addition of mannitol.Method: This was an ambispective cohort study based on consecutive sampling at Cipto Mangunkusumo General Hospital and Mochtar Riady Comprehensive Cancer Centre (MRCCC) Siloam Hospitals. The data was obtained from September 2017 to February 2018. The choice of mannitol administration based on responsible physician clinical judgement. The outcome was any increment more than 0,3 mg/dl or 1,5 times from baseline of serum creatinine. Analysis was done by using SPSS statistic for univariate, bivariate and multivariate logistic regression to obtain crude risk ratio and adjusted risk ratio of cisplatin induced acute kidney injury probability of mannitol addition on hydration.Result: Data from 110 patients (57,3% male) with a median age of 44,5 years (range 19 to 60 years) were collected; 47 received saline alone and 63 received saline with addition of mannitol. Acute kidney injury were higher in mannitol vs non mannitol group. Bivariate analysis showed higher probability of post chemotherapy AKI in mannitol group (RR 2,168; 95% CI 0,839-5,6). On multivariate analysis the adjusted RR was 3,52 (95% CI 1,11-11,162; p value = 0,033) by controlling age.Conclusion: The addition of mannitol on hydration had higher risk of AKI after high dose cisplatin chemotherapy.

Removal From Activity After Sports- Related Concussion in Sex-Comparable Sports From the Michigan High School Athletic Association

Background: Research has demonstrated that female athletes are more likely to report their sports-related concussion (SRC) symptoms compared with male athletes; however, it is unknown if these reporting behaviors correspond to immediate removal from activity in sex-comparable sports. Purpose: To compare the incidence of high school student-athletes removed and not removed from activity after SRC in sex-comparable sports in Michigan. Study Design: Descriptive epidemiology study. Methods: Participants included student-athletes diagnosed with SRC participating in Michigan High School Athletic Association–sponsored athletic activities (22 sex-comparable sports) between 2016 and 2019. All SRCs were recorded in the association’s Head Injury Reporting System (HIRS) by certified athletic trainers, administrators, or coaches. Removal from activity indicated that the student-athlete was removed from play at the time of an injury event. If the student-athlete reported that his or her suspected injury event occurred earlier during activity or if symptom onset was delayed, “not removed from activity” was entered into the HIRS. Incidence proportions were calculated by dividing SRCs not removed by total SRCs in each sport. Risk ratios were calculated by dividing the incidence proportions of girls not removed by boys not removed in each sport. Results: A total of 4418 (2773 female, 1645 male) SRCs were reported, with the most occurring in female soccer players (n = 1023). Overall, 515 girls and 243 boys were not removed from activity, resulting in incidences of 0.19 (95% CI, 0.17-0.20) and 0.15 (95% CI, 0.13-0.17), respectively. Across all sports, girls were 1.26 (95% CI, 1.09-1.45) times as likely to not be removed from activity compared with boys. Of the sports with the most SRCs—soccer, basketball, baseball/softball, and lacrosse—girls had 1.37 (95% CI, 1.09-1.72), 1.15 (95% CI, 0.89-1.47), 1.19 (95% CI, 0.77-1.84), and 1.35 (95% CI, 0.94-1.95) times the risk of not being removed, respectively. Conclusion: Girls were at greater risk of not being removed from activity compared with boys in sex-comparable sports. Results from this study should be incorporated into SRC education in Michigan and potentially elsewhere to inform affiliated personnel of potential sex differences and protect female student-athletes from further harm.

Functional dystonia in the foot and ankle

Aims To assess the characteristic clinical features, management, and outcome of patients who present to orthopaedic surgeons with functional dystonia affecting the foot and ankle. Methods We carried out a retrospective search of our records from 2000 to 2019 of patients seen in our adult tertiary referral foot and ankle unit with a diagnosis of functional dystonia. Results A total of 29 patients were seen. A majority were female (n = 25) and the mean age of onset of symptoms was 35.3 years (13 to 71). The mean delay between onset and diagnosis was 7.1 years (0.5 to 25.0). Onset was acute in 25 patients and insidious in four. Of the 29 patients, 26 had a fixed dystonia and three had a spasmodic dystonia. Pain was a major symptom in all patients, with a coexisting diagnosis of chronic regional pain syndrome (CRPS) made in nine patients. Of 20 patients treated with Botox, only one had a good response. None of the 12 patients who underwent a surgical intervention at our unit or elsewhere reported a subjective overall improvement. After a mean follow-up of 3.2 years (1 to 12), four patients had improved, 17 had remained the same, and eight reported a deterioration in their condition. Conclusion Patients with functional dystonia typically presented with a rapid onset of fixed deformity after a minor injury/event and pain out of proportion to the deformity. Referral to a neurologist to rule out neurological pathology is advocated, and further management should be carried out in a movement disorder clinic. Response to treatment (including Botulinum toxin (Botox) injections) is generally poor. Surgery in this group of patients is not recommended and may worsen the condition. The overall prognosis remains poor. Cite this article: Bone Joint J 2021;103-B(6):1127–1132.

95 Growing Up with Burn Injuries - Has the Experience Changed Over Time?

Introduction Growing up with disfigurement and functional limitations resulting from childhood burns can be challenging. Initial stages of care involve painful surgeries/dressing changes, strenuous physical & occupational therapy, pressure garments and time away from family/school activities. Few studies have examined the voiced issues faced by youth while maturing with burns. This study’s purpose was to determine if experiences in the post-injury phase differed between currently burn-injured youth vs. young adults burned as children. Methods A prior study asked Child Burn Survivors (CBS -10–16 yrs.) and Young Adults (YAs -17-25yrs.) to answer the statement: “The hardest thing about being burned is…” The most common issues included: People Staring, Getting Unwanted Questions, Being Bullied, Remembering When I Was Burned, Having Additional Surgeries and My Scars. The current study asked participants to rate items on a 4-point scale from (1) Not at all to (4) Really a lot. The YAs were asked to consider issues they encountered maturing with burns. Results Child Survivors (CBS, n=147) mean age 13.4 years, male (n=46%) female (n=54%), and YA Survivors (YA, n = 81) male(n=39%) female (n=61%) mean age =19.1 yrs. and were predominately racial/ethnic minorities (CBS=67%; YA = 58%). No differences existed for age burned (CBS=6 yrs. vs. YA = 6.4 yrs.) hidden & visible scars (CBS=55% vs. YA=68%) and TBSA &gt; 50% (CBS=19% vs. YA =20%). Top mean scores for CBS’s included: Remembering the Burn (2.05) & Getting Unwanted Questions (2.0). The YA group’s top mean scores included Being Bullied (2.10) & People Staring (2.0). The CBS group reported that Getting Unwanted Questions was more problematic than the YA Group (p =003). YAs shared that Being Bullied was their biggest problem vs. CVS, significantly more so (p=.01). Conclusions Bullying appears to be less of a problem for current child burn survivors than those previously burned. The difference may be due to a recent emphasis placed on anti-bullying in US schools. Findings highlight an ongoing need to address the psycho/social issues related to burns. Teaching interventions like the Phoenix Society’s Rehearse Your Response can help youth address unwanted questions and staring. Providing children an opportunity to process the injury event may also improve their ability to cope with burn stressors.
