The impact of school uniforms on primary school student's physical activity at school: outcomes of a cluster randomized controlled trial.

BACKGROUND: Many school-based physical activity (PA) interventions are complex and have modest effects when delivered in real world contexts. A commonly reported barrier to students' PA, particularly among girls, are uniforms that are impractical (e.g. tunic/dress and black leather shoes). Modifying student uniforms may represent a simple intervention to enhance student PA. The primary aim of this trial was to assess the impact of a PA enabling uniform intervention (shorts, polo shirt and sports shoes) on girls' moderate-to-vigorous physical activity (MVPA) and total PA i.e. counts per minute (cpm). METHODS: A cluster randomized controlled trial was undertaken in 42 primary schools in New South Wales, Australia. Schools were randomized on one school day to the intervention group, where students wore a PA enabling uniform (their sports uniform) or a control group, where students wore their usual traditional uniform. Student PA was measured using wrist-worn Actigraph GT3X and GT9X accelerometers. Linear mixed models controlling for student characteristics were used to examine the effects of the intervention.. RESULTS: Of the 3351 eligible students, 2315 (69.1%) had parental consent and 2180 of these consenting students participated (94.2%) of which 1847 (84.7%) were included in the analysis. For the primary aim the study found no significant differences between girls at schools allocated to the intervention relative to the control on change in MVPA (0.76 min, 95% CI - 0.47 to 1.99, p = 0.22) or cpm (36.99, 95% CI - 13.88 to 87.86, p = 0.15). Exploratory analysis revealed small effects for a number of findings, including significant reduction in sedentary activity (- 1.77, 95% CI - 3.40 to - 0.14, p = 0.035) among all students at schools allocated to the intervention, and non-significant improvements in girls' light intensity PA (1.47 min, 95% CI - 0.06 to 3.00, p = 0.059) and sedentary activity (- 2.23 min; 95% CI - 4.49 to 0.02, p = 0.052). CONCLUSION: The findings suggests that the intervention may yield small improvements in some measure of PA and require substantiation in a larger RCT with longer-term follow-up. The inclusion of additional intervention components may be required to achieve more meaningful effects. TRIAL REGISTRATION: The trial was prospectively registered with Australian New Zealand Clinical Trials Register ACTRN12617001266358 1st September 2017.

A survey of Japanese physician preference for attire: what to wear and why.

Many studies have examined the impression made on patients by physicians' attire. Regardless of practice location, many patients express most confidence in physicians who wear white coats. The number of physicians in Japan who choose not to wear white coats in practice has been increasing, particularly in primary care settings. However, very few studies have examined physician preference for attire. To clarify Japanese general practitioners' preference for attire by practice setting, we conducted a survey of physician preferences and reasons for attire selection. Subjects were 794 general practitioners certified by the Japan Primary Care Association and recruited from a mailing list. We conducted a web-based questionnaire survey. Physicians were asked to choose one of four different dress styles (semi-formal, white coat, scrubs, and casual) for different practice settings and state the reasons for selection. The response rate was 19.3% (n = 153; men 112). Most subjects chose white coats as usual attire for hospital practice (52%), mainly because of custom and professionalism. In contrast, most subjects chose non-white coats for clinics (59%) and home care (hospital-provided, 58%; clinic-provided, 71%). More subjects chose casual dress for clinic and home care practice, mainly to appear empathic. Most subjects chose white coats as the most appropriate hospital attire (54%), mainly because of patient perceptions of this attire being professional. Most subjects considered non-white coat attire more appropriate for clinic and home care practice. The findings indicate that general practitioners choose their clothes depending on practice location.

Simulation metamodeling approach to complex design of garment assembly lines.

The today's competitive advantage of ready-made garment industry depends on the ability to improve the efficiency and effectiveness of resource utilization. Ready-made garment industry has long historically adopted fewer technological and process advancement as compared to automotive, electronics and semiconductor industries. Simulation modeling of garment assembly line has attracted a number of researchers as one way for insightful analysis of the system behaviour and improving its performance. However, most of simulation studies have considered ill-defined experimental design which cannot fully explore the assembly line design alternatives and does not uncover the interaction effects of the input variables. Simulation metamodeling is an approach to assembly line design which has recently been of interest to researchers. However, its application in garment assembly line design has never been well explored. In this paper, simulation metamodeling of trouser assembly line with 72 operations was demonstrated. The linear regression metamodel technique with resolution-V design was used. The effects of five factors: bundle size, job release policy, task assignment pattern, machine number and helper number on throughput of the trouser assembly line were studied. An increase of the production throughput by 28.63% was achieved for the best factors' setting of the metamodel.

What Should I Wear to Clinic? A National Survey of Pediatric Orthopaedic Patients and Parents.

BACKGROUND: A number of factors have been shown to affect how surgeons are subjectively viewed, including their appearance in clinic. Patient preference for pediatric orthopaedic surgeon attire has not previously been studied, nor has its influence on initial perception of the surgeon. METHODS: At 5 pediatric regional sites across the United States, parents and patients presenting to the pediatric orthopaedic clinic were given anonymous surveys showing 8 photos of surgeons in different clinical dress including in business or scrub dress, each with or without white coat (WC). Subjects reported their demographics, single preferred photo, rated characteristics of the surgeons in each photo on a 5-point Likert scale, and answered specific questions on scrubs and WCs. The first consecutively completed 100 parent and 100 patient surveys were included from each site. RESULTS: One thousand surveys were collected from patients (500) and parents (500). The majority felt a surgeon's clinical dress would not affect how they are cared for (83%), and that it was ok to wear scrubs in clinic (90%). Overall, WC was preferred to those without no matter the age, but there was no difference between scrub and business choices. Of those stating a preference, woman in business and WC (24%) and woman in scrubs and WC (21%) were most selected, with the only geographic difference being the midwest's preference for man in business and WC. Females were more likely to prefer women photographs (P<0.0001). CONCLUSIONS: In general, pediatric orthopaedic patients and parents do not have a strong specific preference toward what their surgeon wears to clinic, including whether or not we are dressed in scrubs, but some initial biases exist. When asked to choose, the traditional WC worn over any attire is preferred, and female patients and parents uncover a preference for a surgeon of their own sex. LEVEL OF EVIDENCE: Level III.

Basic social resource needs screening in the gynecologic oncology clinic: a quality improvement initiative.

BACKGROUND: Social determinants of health are known to contribute to disparities in health outcomes. Routine screening for basic social needs is not a part of standard care; however, the association of those needs with increased healthcare utilization and poor compliance with guideline-directed care is well established. OBJECTIVE: In this study, we aimed to assess the prevalence of basic social resource needs identified through a quality improvement initiative in a gynecologic oncology outpatient clinic. In addition, we aimed to identify clinical and demographic factors associated with having basic social resource needs. STUDY DESIGN: We performed a prospective cohort study of women presenting to a gynecologic oncology clinic at an urban academic institution who were screened for basic social resource needs as part of a quality improvement initiative from July 2017 to May 2018. The following 8 domains of resource needs were assessed: food insecurity, housing insecurity, utility needs, financial strain, transportation, childcare, household items, and difficulty reading hospital materials. Women with needs were referred to resources to address those needs. Demographic and clinical information were collected for each patient. The prevalence of needs and successful follow-up interventions were calculated. Patient factors independently associated with having at least 1 basic social resource need were identified using multivariable Poisson regression. RESULTS: A total of 752 women were screened in the study period, of whom 274 (36%) reported 1 or more basic social resource need, with a median of 1 (range, 1-7) need. Financial strain was the most commonly reported need (171 of 752, 23%), followed by transportation (119 of 752, 16%), difficulty reading hospital materials (54 of 752, 7%), housing insecurity (31 of 752, 4%), food insecurity (28 of 752, 4%), household items (22 of 752, 3%), childcare (15 of 752, 2%), and utility needs (13 of 752, 2%). On multivariable analysis, independent factors associated with having at least 1 basic social resource need were being single, divorced or widowed, nonwhite race, current smoker, nonprivate insurance, and a history of anxiety or depression. A total of 36 of 274 (13%) women who screened positive requested assistance and were referred to resources to address those needs. Of the 36 women, 25 (69%) successfully accessed a resource or felt equipped to address their needs, 9 (25%) could not be reached despite repeated attempts, and 2 (6%) declined assistance. CONCLUSION: Basic social resource needs are prevalent in women presenting to an urban academic gynecologic oncology clinic and can be identified and addressed through routine screening. To help mitigate ongoing disparities in this population, screening for and addressing basic social resource needs should be incorporated into routine comprehensive care in gynecologic oncology clinics.

Patient Preferences for Physician Attire: A Multicenter Study in Japan.

BACKGROUND: Previous studies have shown that patients have specific expectations regarding physician dress. Japan has a cultural background that is in many ways distinct from western countries. Thus, physician attire may have a different impact in Japan. METHODS: We conducted a multicenter, cross-sectional study to examine patients' preferences for and perceptions of physician attire in Japan. The questionnaire was developed using photographs of either a male or female physician dressed in seven different forms of attire, and it was randomly distributed to inpatients and outpatients. Respondents were asked to rate the provider pictured; they were also asked to provide preferences for different forms of attire in varied clinical settings. Preference was evaluated for five domains (knowledgeable, trustworthy, caring, approachable, and comfortable). We also assessed variation in preferences for attire by respondent characteristics. RESULTS: A total of 1,233 (61%) patients indicated that physician dress was important, and 950 (47%) patients agreed that it influenced their satisfaction with care. Compared with all forms, casual attire with a white coat was the most preferred dress. Older patients more often preferred formal attire with a white coat in primary care and hospital settings. In addition, physician attire had a greater impact on older respondents' satisfaction and experience. CONCLUSION: The majority of Japanese patients indicated that physician attire is important and influenced their satisfaction with care. Geography, settings of care, and patient age appear to play a role in patient preferences.

An analysis of children's clothing-related injuries cases reported by the media in mainland of China from 2003 to 2017.

BACKGROUND: Numerous reports in the media have suggested that children could be hurt due to their clothing, yet there are few medical reports that discussed children's clothing-related injuries. This study therefore, aimed to describe the epidemiological characteristics of media-reported injury cases related to children's clothing in Mainland of China. METHODS: This study systematically collected a total of 192 cases of children's clothing-related injuries reported in the news reports and medical literatures published by the Chinese media before December 2017. A content analysis of these cases was conducted to obtain information on the characteristics of these injuries. RESULTS: Cases of clothing-related injuries were most common in children aged 3 to 6 years (54.7%); the ratio of the number of boys to the number of girls in the 192 cases was 1.5: 1. In addition, approximately 51% of the cases occurred in the region of East China. The most common location of the incidents was in the home (35%). Furthermore, the zippers are the most common cause of injuries (15.1%), and the most common injured body part was the genital organs (29.2%). Besides, there were 24 cases reported death related to clothing injuries (13%). Moreover, the locations where the injuries occurred, the reasons for the occurrence of the injuries and the injured body parts differed significantly by gender and age (P < .05). CONCLUSIONS: Our findings suggest that future unintentional injuries could be prevented by implementing 2 major initiatives: improving the promotion of the safety of children clothing design in China and educating consumers on the potential risk associated with children's clothing.

Women's use of intimate apparel as subtle sexual signals in committed, heterosexual relationships.

Current literature on women's sexual signaling focuses on modes of attracting potential, new sexual partners, but says little about women's subtle sexual signals in committed, romantic relationships. Subtle sexual signals are inherently private and are only visible to the intended audience; a woman might use these signals to elicit or accept a sexual response from her partner or to increase her overall attractiveness, or attractivity. In this study, we sought to identify women's use of intimate apparel as a proceptive or receptive behavior as well as the effects of relative mate value, relationship commitment, relationship satisfaction, and sexual functioning. A total of N = 353 women in the United States aged 25-45 who were in committed, heterosexual relationships completed the survey; 88.7% of the sample indicated wearing or having worn sexy underwear. Results indicate that women report wearing sexier underwear the day taking the survey if they anticipate sexual activity that same day. However, during the most recent sexual activity, women did not report wearing sexier underwear if they initiated (proceptive) that activity. While relative mate value was not directly related to sexiness of intimate apparel, women who report higher mate value tend to wear sexier underwear. Women's use of intimate apparel might be viewed as a method of increasing attractivity and underlying receptivity to aid relationship maintenance, though caveats regarding measures and alternative interpretations are also discussed. Findings suggest that these women use intimate apparel to feel sexy, desired, aroused, and to prepare for sex with their partners. This study is the first to examine intimate apparel in relationships and as a subtle sexual signal of proceptivity and receptivity.

Low-Intensity Resistance Training and Compression Garment in the Management of Breast Cancer-Related Lymphedema: Single-Blinded Randomized Controlled Trial.

There is limited evidence regarding the combined effect of exercise and compression garment on breast cancer-related lymphedema (BCRL). Therefore, we investigate the effect of low-intensity resistance training alone or in combination with a compression garment on lymphedema volume, self-reported lymphedema symptoms, and shoulder mobility and function. A total of 60 women with unilateral BCRL were randomly assigned to low-intensity resistance exercises (Rex group, n = 30) or exercises and compression garment (Rex-Com-group, n = 30). Both groups take part in exercises program consisted of 10-12 repetitions at 50 to 60% of one repetition maximum (IRM), three times weekly, for 8 weeks. The primary outcome was lymphedema volume determined by percentage reduction of excess limb volume (ELV). Secondary outcomes were lymphedema symptoms (pain, heaviness, and tightness) and shoulder mobility and function using the disabilities of the arm, shoulder, and hand (DASH) questionnaire. All measurements were standardized and performed before (week 0, W0), after the intervention (week 8, W8), and at follow-up (week 12, W12). A significant reduction in percentage of ELV (p < 0.01), pain severity (p < 0.05), a sensation of heaviness (p < 0.05) and tightness (p < 0.001), and improvement in shoulder range of motion (p < 0.05) and function on DASH scores (p < 0.05) were observed at W8 and W12 in both groups. However, no between-group differences were observed over time. These findings suggest that low-intensity resistance training, irrespective of garment use, can effectively reduce limb volume and lymphedema symptoms, and increase shoulder mobility and function.

Intensive Care Neonates and Evidence to Support the Elimination of Hats for Safe Sleep.

BACKGROUND: Although the incidence of sudden unexplained infant deaths has decreased over time with the use of safe sleep practices, one area that remains unclear is the safety of hats during infant sleep. PURPOSE: Decrease the risk of overheating or suffocation by removing NICU infants' hats during sleep without increasing the relative risk of hypothermia during transition to an open crib. METHODS: Removal of hats for routine thermoregulation, beyond the initial infant resuscitation and stabilization of NICU infant was implemented in 2015. Retrospective chart audits were conducted on all NICU infants between February 2015 and December 2016. Hypothermia (≤ 97.6°F) data during transition to an open crib was collected. Exclusion criteria included concurrent diagnosis of: sepsis, hyperbilirubinemia, congenital anomaly inhibiting infants thermoregulation and noncompliance with unit guideline for weaning infant to open crib. FINDINGS: Over 18 months, 2.7% of infants became hypothermic (≤ 97.6°F) during transition to open crib, requiring return to isolettes. IMPLICATIONS FOR PRACTICE: Hats were found to be unnecessary in maintaining thermoneutrality after weaning infants toan open crib in our NICU. By avoiding the use of hats in an open crib, it's possible infants will avoid overheating and a risk of suffocation, creating a safer sleep environment. IMPLICATIONS FOR RESEARCH: The removal of hats during sleep to promote infant health should be considered for all infants.

A pilot survey of Southeastern firefighters: Safety practices, use of protective gear, and injury.

INTRO: There were over 60 firefighter line of duty deaths and roughly 30,000 injuries in the United States in 2016. Modern thermoprotective gear has reduced the risks firefighters face from both thermal and inhalation injury, but must be used properly to be effective. The purpose of this study is to examine gear use and associated injury in firefighters. METHODS: Surveys were distributed with questions about demographics, gear usage, and maintenance practices. If previously injured, firefighters described the injury, treatment, and recovery. RESULTS: Of the 50 surveys distributed, 37 were returned (72%). A majority of respondents (70%) reported wearing incomplete gear. Those who reported injury were more likely to have omitted gear (81% vs 45%). For all respondents, the items most commonly omitted were hood (58%), gloves (22%), and earflaps (22%). Regular cleaning of gear was not practiced by 39% of burned respondents and 46% had not had their gear sized within 2 years. Serious burns were reported by 41% of respondents. Mean burn size was 7% total body surface area (TBSA), and 11% reported self-treating their burns, including 63.5% who continued to work despite suffering a 2nd or 3rd degree burn injury. Only 17% were treated at a burn center, and this group missed anywhere from two shifts to 8 months of work. CONCLUSIONS: Firefighters risk injury by omitting gear and not adhering to National Fire Protection Association (NFPA) guidelines on gear sizing, maintenance, and station wear. Firefighters also frequently self-treat serious burns despite unique considerations regarding re-injury. National trends related to gear use and injury risk should be studied further, and standards should be developed for ensuring safe return to work.

Understanding patient preference for physician attire in ambulatory clinics: a cross-sectional observational study.

OBJECTIVES: We explored patient perceptions regarding physician attire in different clinical contexts and resultant effects on the physician-patient relationship. SETTING: The 900-bed University Hospital Zurich, Switzerland. PARTICIPANTS: A convenience sample of patients receiving care in dermatology, infectious diseases and neurology ambulatory clinics of the University Hospital Zurich participated in a paper-based survey. PRIMARY AND SECONDARY OUTCOME MEASURES: The survey instrument was randomised and showed photographs of male or female physicians wearing various forms of attire. On the basis of the respondents' ratings of how the physician's attire affected perceptions across five domains (knowledgeable, trustworthy, caring, approachable and comfort with the physician), a composite preference score for attire was calculated as the primary outcome. Secondary outcomes included variation in preferences by respondent characteristics and context in which care was provided. RESULTS: Of 834 patient respondents (140 in dermatology, 422 in infectious diseases and 272 in neurology), 298 (36%) agreed that physician attire was important. When compared with all available choices, the combination of white scrubs with white coat was rated highest while a business suit ranked lowest. Variation in preferences and opinions for attire were noted relative to respondent demographics and the clinical setting in which the survey was administered. For example, compared with younger patients, respondents ≥65 years of age more often reported that physician dress was both important to them and influenced how happy they were with their care (p=0.047 and p=0.001, respectively). CONCLUSIONS: Outpatients at a large Swiss University hospital prefer their physicians to be dressed in white scrubs with white coat. Substantial variation among respondents based on demographics, type of physician and clinical setting were observed. Healthcare systems should consider context of care when defining policies related to dress code.

Brief versus Thong Hygiene in Obstetrics and Gynecology (B-THONG): A survey study.

AIM: The aim of this study was to evaluate if thong use is associated with a higher report of urogenital infections, including urinary tract infections, yeast vaginitis and bacterial vaginosis. METHODS: A cross-sectional survey regarding underwear preferences and infectious history was designed and distributed to women via a crowdsourcing service. All survey questions related to the last 12 months. Parametric and nonparametric statistical methods were used to compare responses between thong wearers and nonthong wearers. Thong wearers were defined as women who wore a thong equal to or more than 50 % of the time. RESULTS: Nine hundred and eighty-six respondents met inclusion criteria and completed the survey; 186 (18.9%) were defined as thong wearers and 800 (81.1%) were defined as nonthong wearers in the last 12 months. Reported rates of urogenital infections in the last 12 months were not significantly different for thong wearers versus nonthong wearers. Thong use was not an independent predictor of any urogenital infection in this study. CONCLUSION: In this large cross-sectional study we found that oral sex was the only independent predictor of urinary tract infection and bacterial vaginosis, and that wearing noncotton crotch underwear was associated with yeast vaginitis. Wearing thong underwear was not associated with any urogenital infections. Medical providers should discuss sexual practices and underwear fabric, rather than style, with their patients when there is concern for urogenital infection.

The Effect of Wearing White Coats on Patients' Appreciation of Physician Communication during Postpartum Rounds: A Randomized Controlled Trial.

OBJECTIVE: Wearing a white coat (WC) has been associated with risk of colonization and transmission of resistant pathogens. Also, studies have shown that physicians' attire in general affects patients' confidence in their physician and the patient-physician relationship. Our objective is to evaluate the hypothesis that not wearing a WC during physician postpartum rounds does not affect patient-physician communication scores. MATERIALS AND METHODS: This is an unblinded, randomized, parallel arms, controlled trial of postpartum women at a single university hospital. Women were randomly assigned to having their postpartum physicians' team wear a WC or not (no-WC) during rounds. Our primary outcome was "patient-physician communication" score. Univariable and multivariable analysis were used where appropriate. RESULTS: One hundred and seventy-eight patients were enrolled (87 in WC and 91 in no-WC groups). Note that 40.4% of patients did not remember whether the physicians wore a WC or not. There was no difference in the primary outcome (p = 0.64) even after adjusting for possible confounders. CONCLUSION: Not wearing a WC during postpartum rounds did not affect the patient-physician communication or patient satisfaction scores. In the setting of prior reports showing a risk of WC pathogen transmission between patients, our findings cannot support the routine wearing of WCs during postpartum rounds.

Professional Image and the Nursing Uniform.

BACKGROUND: Traditional nursing uniforms have evolved and influenced nursing image, but professional image in nursing is unique and unclear. Institutional policies dictate uniform and appearance standards that portray professionalism in health care environments. METHOD: Nurses were questioned using three structured open-ended questions about the nursing uniform and its effects on patients' perceptions of professionalism. Qualitative line-by-line analyses of transcribed data were conducted to identify emerging themes using van Manen's phenomenology. RESULTS: Participants wore varying uniforms while in nursing school. The influences of uniform evolution on patients' perceptions of professionalism were acknowledged along with current challenges in maintaining a professional image in nursing. CONCLUSION: Findings will be used for future exploration of the concept of professional image to improve educational practices that promote a professional work environment and professional image for the discipline.

Type of underwear worn and markers of testicular function among men attending a fertility center.

STUDY QUESTION: Is self-reported type of underwear worn associated with markers of testicular function among men at a fertility center? SUMMARY ANSWER: Men who reported most frequently wearing boxers had higher sperm concentration and total count, and lower FSH levels, compared to men who did not. WHAT IS KNOWN ALREADY: Elevated scrotal temperatures are known to adversely affect testicular function. However, the epidemiologic literature on type of underwear, as a proxy of scrotal temperature, and male testicular function is inconsistent. STUDY DESIGN, SIZE, DURATION: This is a cross-sectional study including 656 male partners of couples seeking infertility treatment at a fertility center (2000-2017). PARTICIPANTS/MATERIALS, SETTING, METHODS: Self-reported information on type of underwear worn was collected from a take-home questionnaire. Semen samples were analyzed following World Health Organization guidelines. Enzyme immunoassays were used to assess reproductive hormone levels and neutral comet assays for sperm DNA damage. We fit linear regression models to evaluate the association between underwear type and testicular function, adjusting for covariates and accounting for multiple semen samples. MAIN RESULTS AND THE ROLE OF CHANCE: Men had a median (interquartile range) age of 35.5 (32.0, 39.3) years and BMI of 26.3 (24.4, 29.9) kg/m2. About half of the men (53%; n = 345) reported usually wearing boxers. Men who reported primarily wearing boxers had a 25% higher sperm concentration (95% CI = 7, 31%), 17% higher total count (95% CI = 0, 28%) and 14% lower serum FSH levels (95% CI = -27, -1%) than men who reported not primarily wearing boxers. Sperm concentration and total count were inversely related to serum FSH. Furthermore, the differences in sperm concentration and total count according to type of underwear were attenuated after adjustment for serum FSH. No associations with other measured reproductive outcomes were observed. LIMITATIONS, REASONS FOR CAUTION: Our results may not be generalizable to men from the general population. Underwear use was self-reported in a questionnaire and there may be misclassification of the exposure. The cross-sectional design limits causal inference, and residual confounding is still possible owing to lack of information on other modifiable life styles that can also modify scrotal heat (e.g. type of trousers worn, textile fabric of the underwear). Blood sampling was not limited to the morning and, as a result, we may have missed associations with testosterone or other hormones with significant circadian variation despite statistical adjustment for time of blood draw. WIDER IMPLICATIONS OF THE FINDINGS: Certain styles of male underwear may impair spermatogenesis and this may result in a compensatory increase in gonadotrophin secretion, as reflected by higher serum FSH levels among men who reported most frequently wearing tight underwear. Confirmation of these findings, and in particular the findings on FSH levels suggesting a compensatory mechanism, is warranted. STUDY FUNDING/COMPETING INTEREST(S): The project was financed by Grants (R01ES022955, R01ES009718, P30ES000002, and K99ES026648) from the National Institutes of Health. None of the authors has any conflicts of interest to declare.

Simplified Method for Rapid Field Assessment of Visual Acuity by First Responders After Ocular Injury.

Objective: Initial visual acuity after ocular injury is an important measure, as it is an accurate predictor of final visual outcome and gives a rapid estimation of the overall severity of the injury, thereby aiding evacuation prioritization. We devised a simple method for rapidly assessing visual acuity in the field without having to rely on formal screening cards. Methods: Using common objects, icons, and text found in the injury zone - for example, common military name tapes, rank insignias, patches, emblems, and helmet camouflage bands, which will be known collectively as the Army Combat Optotypes (ACOs) - a Snellen-equivalent method of assessing visual acuity was devised and correlated to the ocular trauma score (OTS). Results: Ability to read the ACOs at 2, 3, and 5 ft correlates with acuities in the range from 20/20 to 20/400. Identification of ACOs with visual acuity of 20/50 and 20/200 approximates important inflection points of severity for the OTS. Conclusion: Accurately assessing visual acuity in the field after ocular injury provides essential information but does not require sophisticated screening equipment. Pertinent and accurate acuities can be rapidly estimated using commonly available text or graphical icons such as standard name tapes, patches, and rank insignias.
