Caregiver alignment with triage acuity levels and drivers for discrepancy between caregiver assessment and triage acuity levels: a cross-sectional questionnaire based study

BackgroundCaregiver concern is the main driver to paediatric emergency departments visits. Understanding caregiver worries is crucial to guide patients to the most appropriate healthcare setting. Previous research shows mixed findings on the accordance between caregiver assessment and professional triage.MethodsWe assessed data from two questionnaire-based studies conducted over 27 months in two tertiary paediatric emergency departments in Switzerland to compare caregiver perception of their child’s medical acuity and standard nurse triage. Furthermore, we examined socioeconomic factors associated with caregiver perception.ResultsOur study of 2,126 children seen in the two paediatric emergency departments showed that caregiver assessment aligned well with the acuity assigned by professional triage in 89% (1,901/2,126) of cases. In 142 cases (7%, 142/2,126), caregivers rating their child’s severity higher than nurse’s triage while in 83 cases (4%, 83/2,126), they rated it lower. In an univariable analysis, we found that family’s difficulties paying bills (20% vs. 12%) and low maternal education (19% vs. 10%) were associated with a higher percentage of caregiver rating their child’s severity higher than nurse’s triage. Fever as the main complaint was associated with caregiver rating their child’s severity lower than nurse’s triage.ConclusionsThis questionnaire-based study shows that caregiver’s assessment of the severity of the child and nurse triage are concordant in most situations. Our study sheds light on the association between caregiver assessment and professional triage in two paediatric emergency departments in Switzerland, revealing some of the factors leading to discordance. These factors most probably reflect health illiteracy. It is important that healthcare professionals recognize and address factors influencing caregiver assessments to facilitate accurate decision-making and enhanced paediatric emergency care outcomes.

Improvement of stereopsis following strabismus surgery in adults: a retrospective analysis.

Adults who undergo strabismus surgery, in addition to cosmesis, could benefit from improved stereopsis. This improvement is associated with the performance of motor skill tasks in young adults; they reduce the risk of tripping or falling during everyday locomotion and improve reading efficiency. This study aimed to assess stereopsis level after strabismus surgery in adults who underwent strabismus surgery for any reason. Retrospective observational study of adult patients who underwent strabismus surgery at our institution between 2010 and 2022. One hundred and thirty-two patients were included. Postoperatively, 48% had a stereo acuity better than 100 seconds of arc, and only 21.5% had no stereopsis. The most significant factor influencing improved stereopsis after surgery was the angle of strabismus postoperatively (p = 0.018). There was a statistically significant correlation between fusion at a distance and the stereo acuity (p = 0.0337). There was no statistically significant correlation between the stereo acuity level and the strabismus angle of deviation, the strabismus direction (vertical, horizontal, or combined), or the type (esotropia or exotropia) before or after the surgery. Although not statistically significant (p = 0.6579), the underlying cause categories were correlated with the stereo level. Patients with neurological causes demonstrated higher levels of stereopsis, followed by TED, whereas patients with childhood strabismus have the lowest probability of regaining stereopsis after surgery. Although long-standing strabismus reduces the potential for binocularity, surgery may be beneficial and improve stereopsis regardless of the cause of strabismus.

Safety and Vision Outcomes Following Gene Therapy for Bietti Crystalline Dystrophy

Bietti crystalline dystrophy (BCD) is a severe genetic retinopathy caused by variants in the CYP4V2 gene. Currently, there is no approved treatment for BCD. To evaluate safety and vision outcomes following gene therapy with adeno-associated virus (AAV) encoding CYP4V2 (rAAV-hCYP4V2, NGGT001 [Next Generation Gene Therapeutics]). This open-label, dose-escalation nonrandomized clinical trial was conducted from February 2023 to May 2024 at 2 study sites in China. Patients with genetically confirmed biallelic disease-linked CYP4V2 variants received subretinal injections of rAAV2-hCYP4V2 at 1 of 2 dosage levels and were followed up for 12 months. A single unilateral injection of 1.5 × 1011 or 3.0 × 1011 total vector genomes of recombinant AAV-hCYP4V2 in the worse eye, based on visual acuity letter score. The primary outcome was safety, assessed by clinical examination of ocular inflammation and evaluated by routine clinical chemistry and immunogenicity testing. Secondary outcomes were changes in visual function from baseline in best-corrected visual acuity (BCVA), microperimetry, and contrast sensitivity 12 months after treatment. Among 12 patients with BCD (6 patients per dose group), mean (SD) patient age was 40.5 (7.1) years, and 5 patients (42%) were female. No severe adverse events related to the treatment were observed. However, mild intraocular inflammation was noted in 1 participant. The median (IQR) baseline BCVA letter score for the study eye was 34 (10-53), equivalent to 20/200 Snellen, while the nonstudy eye had a median (IQR) BCVA of 60 (40-67), equivalent to approximately 20/63 Snellen. At 12 months, the study eye improved by a mean (SD) letter score of 13.9 (13.1) compared with 6.3 (7.4) in the nonstudy eye. The 12-month median (IQR) BCVA for the study eye was 53 (37-64) (equivalent to approximately 20/80 Snellen) and 62 (42-70) (approximately 20/50 Snellen) for the nonstudy eye. This open-label, exploratory nonrandomized clinical trial identified no serious safety concerns related to gene therapy over 12 months' follow-up among patients with BCD. While improvement in BCVA was noted, the magnitude was within test-retest values typically noted in eyes with very low levels of visual acuity, and BCVA improvement in both the study and nonstudy eyes could be related to a learning effect, with greater improvement in the study eye possibly related to study eyes' being the worse-seeing eye.

Length of stay in the pediatrics emergency department and associated factors among pediatrics patients in Eastern Ethiopia public hospital, Ethiopia 2022.

Patient length of stay is a crucial measure of the emergency department, and it is a vital indicator of health services to evaluate its efficacy, patient care, organizational management, and health care system. Despite this, there are a few studies conducted on pediatric emergency length of stay in developing countries. Therefore, this study serves as input for evidence of pediatric emergency length of stay and associated factors in public hospitals. An institution-based cross-sectional study was conducted among children who attended in pediatric emergency department of Eastern Ethiopia public hospital from May 01 to Jun 31, 2022. A total of 761 children were selected by systematic sampling technique and interview using structured questionnaires. After data is collected and cleaned, entered using Epi data version 4.6 and then exported to Stata version 14.1 for analysis. Finally, an AOR with a 95% CI was computed, and variables with a P-value < 0.05 in the multivariable analysis were taken as significant factors for prolonged length of stay. The prevalence of prolonged length of stay in the emergency ward was 214 (72%). Living in a rural residence ([AOR = 1.65, 95% CI (1.10-2.48)], having a duration of pain > = 12 ([AOR = 1.92, 95% CI (1.13-3.25)], waiting time > = 5 minute ([AOR = 2.24, 95% CI (1.1-4.248541)], having comorbid illness ([AOR = 1.92, 95%CI, 1.13-3.25)], and higher acuity level and absence of medication in the hospital were ([AOR = 2.26, 95%CI (1.02-2.46]) were significantly associated factors for prolonged length of stay. This study revealed that more than two-thirds of children admitted to pediatric emergency had prolonged lengths of stay. This result indicated that higher proportion of the length of stay in pediatric emergency in Eastern Ethiopian public hospitals compare to national. Hence, it is better to give priority to strengthening the focused evaluation of important variables and manage accordingly.

Estimating the proportion of telehealth-able U.S. emergency department visits

We use national emergency department (ED) data to identify the proportion of "telehealth-able" ED visits, defined as potentially conductible by Video Only or Video Plus (with limited outpatient testing). We used ED visits by patients 4 years of age and older from the 2019 National Hospital Ambulatory Medical Care Survey and applied survey weighting for national representativeness. Two raters categorized patient-described Reasons for Visit (RFV) as telehealth-able (yes, no, uncertain) for both Video Only and Video Plus visits. This categorization was stratified by age (4 to 17 years old, 18 to 35, 36 to 64, and 65 and older). Visit characteristics that were used to remove further nontelehealth-able visits included admission, procedures, diagnostic testing, acuity level, and pain score. Our sample included 133.6 million United States ED visits in 2019 for patients aged 4 years or older. Of those, between 3.4% and 8.8% of visits were telehealth-able by Video Only and between 5.0% and 9.7% by Video Plus, considering only the first RFV. Visits by younger patients were more often telehealth-able, with the proportion of telehealth-able visits decreasing with advancing age. Considering all RFVs, between 0% to 6.6% of ED visits were telehealth-able with Video Only and 0.02% to 7.6% with Video Plus. Between 3% and 10% of United States ED visits may be potentially telehealth-able for patients aged 4 years and older, considering the first listed RFV and ED visit characteristics. Fewer visits may be telehealth-able when all reasons for visits are considered.

Association between patient race and emergency department physical restraint use in a statewide hospital system

ObjectiveTo measure the association between patient race and physical restraint use in the ED. MethodsAdult patients presenting to eight rural, suburban, and urban EDs in a mid-Atlantic statewide hospital system ED between January 1, 2019 and June 30, 2022 were included. Those arriving already restrained, transported from detention centers, or who left before services were provided were excluded. Multivariable logistic regression measured the association of physical restraint use with patient race, adjusting for age, sex, weight, height, mode of arrival, history of violent behavior, comorbidities, ESI acuity level, homelessness, and site. ResultsOf 896,527 patient encounters included in the analysis, 3459 (0.39 %) had a physical restraint order. The study population was 48.7 % non-Hispanic White and 43.7 % non-Hispanic Black. Black patients had higher adjusted odds of being restrained relative to White patients (OR 1.26, 95 % CI 1.15–1.37). Other key variables associated with physical restraint use were an ESI level of 1 vs 3+ (OR 13.15, 95 % CI 11.49–15.04), arrival by law enforcement (8.39, 95 % CI 7.47–9.43), and arrival by EMS (5.36, 95 % CI 4.93–5.83 Among those who were restrained, the hazard of restraint was higher among Black compared to White patients in the first hour after ED arrival (adjusted hazard ratio 1.14, 95 % CI 1.01–1.30). ConclusionBlack patients were more likely to be physically restrained compared to White patients, though the magnitude of this association was small compared to that of other clinical risk factors. Future work should evaluate if these findings are driven by differences in patient characteristics or clinician decision-making to best inform interventions to reduce this disparity.

Constant high-level visual acuity during total laparoscopic hysterectomy using the OpClear® system

Background Operative vision can frequently be critically reduced during laparoscopic surgery by condensation and other matter accumulating on the distal laparoscope lens. By delivering saline and carbon dioxide across the lens, the OpClear system is designed to maintain operative vision without needing scope removal for lens cleaning. This study evaluates the system’s efficacy in providing high-level visual acuity during laparoscopic hysterectomy while examining its utility through its impact on operative duration. Methods A retrospective audit compared efficacy and utility for the three years before and after the implementation of OpClear in a single unit. Thirty-three cases were reviewed pre-OpClear, while 82 cases were analysed in the post-OpClear group. All cases involved routine total laparoscopic hysterectomies (TLH) performed by the same surgeon (AT) with similar complexity levels. Results The OpClear system provided a consistently high level of visual acuity throughout the laparoscopic procedures. Scope removals, which typically result in non-productive operating time, were virtually eliminated. Consequently, in highly comparable cases, OpClear usage resulted in a 17-minute reduction in operating time over cases performed without the device. Additionally, in the OpClear group, there were trends towards reduced blood loss and shorter hospital stays, with patients in the OpClear group being discharged on first rather than second postoperatively. Conclusions The findings of this audit suggest that the OpClear system provides continuous high-level vision during laparoscopic hysterectomy. Further, reducing periods of non-productive time associated with scope removal for cleaning resulted in shorter operating times. Thus, the system has the potential to enhance safety, improve theatre utilisation and alleviate some of the surgical stresses associated with laparoscopic surgery.

Analysis of dental anatomy knowledge among dental students: A preliminary study.

This study aimed to compare the level of dental anatomy knowledge and visual acuity of dental students throughout their undergraduate course. This descriptive, observational, and cross-sectional study with a quantitative approach was conducted over one year. Thirty-seven students, divided into three groups based on the time spent studying dental anatomy and carving, had their theoretical knowledge and visual acuity assessed using two questionnaires. The former was organized into two groups of questions: (1) related to the anatomy of anterior teeth, and (2) the anatomy of posterior teeth. Data were analyzed using the Kruskal-Wallis test, Wilcoxon test, and Spearman correlation (α=0.05). No statistically significant difference was observed between sexes in the comparison of theoretical knowledge and photograph evaluation. Overall, participants performed similarly on both parts of the questionnaire about theoretical knowledge (anterior teeth group: 5.6±1.94; posterior teeth group: 5.7±2.32) with no statistical difference. There was no significant difference in the theoretical questionnaire results (P=0.615) or in the photograph evaluation (P=0.187) among the periods. In the intra-group comparison, P10 students scored higher in the photograph evaluation than in the theoretical questionnaire, showing a significant difference (P=0.027). No significant correlation was found between theoretical knowledge and sculpture evaluation (r=0.177; P=0.256). Within the limits of this study, it was concluded that students had similar performance in theoretical knowledge of anterior and posterior teeth. However, P10 students performed better in photograph evaluation than in the theoretical questionnaire, suggesting an improvement in practical skills throughout the course.

Digital eye strain and clinical correlates in older adults.

To evaluate the screen time habits, associated symptoms and clinical characteristics of an older population (60years and older) drawn from primary care optometry. Consecutive patients aged 60years and older, who used a digital device for at least 1hour per day, attending for an eye examination at a primary care optometric practice in Dublin, Ireland, were invited to participate. The study gathered information regarding the participant's use of digital devices, the types of devices used and duration of use. Best corrected distance acuity and near vision adequacy for reading and device use was recorded. 401 responses were included in the analysis. Based on a Computer Vision Syndrome Questionnaire (CVS-Q) score≥6, the occurrence of DES in this population was high at 51.6% with females having a higher median score than males. The mean number of hours devices were used for was 4hours. 71% of participants reported symptoms of digital eye strain (DES) when using digital devices. Smart phones were the device type used most by participants but tablets were the device type used for the longest duration. Single vision spectacles were the most commonly used method of visual correction when using digital devices. Participants with better levels of acuity used devices for longer periods than those with poorer acuity. This study provides a valuable insight into the screen habits and likelihood of symptoms of DES in an older population and, is to date, the first of its kind. It shows that the prevalence of DES in older age adult device users is high, at 51.6 %, with a clear link between dry eye and symptoms of DES. Its results will enable optometrists to provide specific advice to this age group on how best to reduce symptoms of DES.

Evaluating emergency nurses' use of and satisfaction with a web-based patient triage app.

Evidence suggests that using a standardised triage system that categorises patients into levels of severity or acuity to prioritise their care can provide the greatest levels of patient safety. The use of a web-based app to record patient triage data can support operational decision-making, reduce the risk of errors and standardise the time it takes to record the data required for accurate triage. This article details one aspect of a three-stage research project undertaken in Thailand which aimed to improve the quality of nurse triage, reduce errors in triage decisions and decrease the time spent on triage through implementation of a patient triage app. The patient information input into the app at initial triage is automatically uploaded into the electronic patient record. The authors report the results of the third stage of the project, which aimed to analyse the feasibility of using the app by evaluating completion of patient records and user satisfaction levels.

Utilizing Lactation Acuity to Improve Lactation Services in a U.S. Hospital.

National staffing guidelines for hospital lactation services do not account for the lactation acuity of breastfeeding patients. Higher acuity breastfeeding couplets require a higher level of knowledge and skill from lactation care providers. In these cases, a referral to an International Board Certified Lactation Consultant (IBCLC) is recommended for appropriate management. Use of a lactation acuity classification system as a clinical practice innovation was implemented at Oklahoma University Medical Center to improve the distribution of staff resources for optimal care of breastfeeding patients. Lactation service reports from this facility, a tertiary care teaching hospital, were reviewed to evaluate staffing, number of lactation consults, reason for and acuity of consults, and time spent. The review included over 10,000 lactation consults completed over a 1-year period. Once the lactation acuity system for IBCLC staff was in place, there was an increased mean direct consult time and acuity level with 85% of IBCLC time allocated to high acuity consults. Trained bedside nurses handled most low-acuity patients. The percentage of patients needing a lactation consult who received one increased along with the number of consults per patient. Data on time spent per consult were stratified by acuity, location, and reason for consult, including details on priority consults for neonatal intensive care unit patients. The productivity of the lactation team was higher with the use of a lactation acuity system compared to without it. The data reported support the use of lactation acuity in making recommendations for staffing of hospital lactation services.

Is There an Impending Epidemic of Myopia in Southeast Asia? An Appraisal of the Evidence

Predictions on the future prevalence of myopia suggest one of the Global Burden of Disease regions will develop an epidemic like in East Asia and Singapore in Southeast Asia. This paper analyses the available evidence on prevalence of myopia in this region, concluding that the bulk of the evidence suggests that the prevalence of myopia at the end of schooling is still modest, although two papers suggest that in young adults in Thailand and Indonesia, the prevalence of myopia may be approaching levels typical of the epidemic of myopia. It also analyses an indicator of expected years of education at school entry, as well as current educational levels of adults, using data from the calculation of the UN Human Development Index. It then analyses the results obtained by the countries of the Southeast Asian region in the PISA international surveys of student achievement. Neither of these educational indicators suggests an impending epidemic of myopia. There is a need for more data to clarify this uncertainty. It is suggested that future collection of data concentrate on determining the prevalence of myopia in young adults finishing their schooling. Even methodology as simple as determining levels of lowered visual acuity in senior school students should be sufficient to resolve the uncertainty. This group provides a sound basis for the prediction of future levels of myopia in the adult population, and avoids the impact of the high levels of myopia and high myopia associated with cataract development that occur in much of Southeast Asia.

Empowering Care Teams: Redefining Message Management to Enhance Care Delivery and Alleviate Oncologist Burnout.

Widespread adoption of secure messaging (SM) provides patients with cancer with unprecedented access to medical providers at the expense of increased workload for oncologists. Herein, we analyze oncology SM clinical content and acuity and translate these to estimated cost savings from reduced appointments. This population-based retrospective cohort study examined the content of patient-initiated SM threads exchanged through the patient portal website or app over 1 year (June 1, 2021-May 31, 2022) at 21 Kaiser Permanente Northern California oncology practices, which typically do not have patient copayments associated with SM. A random sample of 500 SM threads were reviewed and categorized by message content, acuity, and appropriate level of service. Cost and time estimates were used to compare the cost of SM management by oncologists alone versus assisted by medical assistants and nurses. During the study, 41,272 patients initiated 334,053 unique SM threads to 132 oncologists. Of the SM threads reviewed, only 26.8% required oncologist expertise. Based on thread content, the remaining 73.2% may have been better managed by a nurse (38.2%), medical assistant (28.4%), primary care physician (5.4%), or another subspecialty provider (1.2%). Emergency care was recommended in 2.4% of the threads reviewed. Significant medical care was provided to patients in 24.4% of the reviewed threads that would typically require an appointment. We estimate that the SM exchanges provided $11.2 million in care, including $3.6 million in avoided out-of-pocket copayment costs to patients and $7.6 million in missed billing codes. High utilization of SM generates additional workload for oncologists that could mostly be appropriately managed by alternate providers. The magnitude of unreimbursed medical care provided via SM and the use of SM for emergent medical situations creates an urgent need for new practice models. An alternative architecture for triaging, managing, and billing SM could reduce costs and oncologist burnout.

Virtual Triage Early Detection of Inappropriate Care-Seeking Intent Among Patients with Life-Threatening Cardiac Symptoms

Reports indicate that only 19% of patients with prodromal symptoms of sudden cardiac arrest seek the appropriate level of care acuity, which may be due partly to individuals being unable to distinguish which acute symptoms require urgent care. This study evaluated the degree to which patient-users of artificial intelligence-based virtual triage presenting with prodromal symptoms of a possibly life-threatening cardiac condition intended to seek the needed emergency care. A dataset of 746,282 virtual triage patient-users was examined to assess the characteristics of those reporting symptoms of potentially life-threatening cardiac conditions with no intention to seek emergency care. Of 3,968 patient-users over age 35 with severe cardiac symptoms, 89.4% did not plan to seek emergency care. A majority of patient-users did not appear to understand the level of care acuity to seek, or planned to engage self-care or to visit an outpatient physician, instead of seeking emergency care. These findings reinforce the need for much-improved patient education among patients at risk for potentially life-threatening cardiac symptoms which require urgent medical care. Virtual triage (or symptom checkers) with care referral may have value in patient engagement and education to achieve this objective.

Trajectories of functional decline and predictors in long-term care settings: a retrospective cohort analysis of Canadian nursing home residents.

This is a 36months' retrospective longitudinal analysis of LTC residents in five Canadian provinces. Group-based trajectory modelling (GBTM) was performed to identify distinct trajectories and resident attributes associated with membership of the trajectory groups. A total of 204 036 LTC residents were included in this study. Their admission mean age was 83.7years (SD = 8.6), and 63.3% were females. Our model identified four distinct trajectories namely: 'Catastrophic decline' (n= 48 441, 22.7%), 'Rapid decline with some recovery' (n= 27 620, 18.7%), 'Progressive decline' trajectory (n = 30 287, 14.4%), and the 'No/Minimal decline' (n= 97 688, 47.9%) Residents' admission ADL Hierarchy score was the single, strongest predictor of functional decline trajectory that residents followed. Residents with ADLH 5-6 OR 0.03 (0.03-0.04) were least likely to follow a catastrophic decline trajectory, while those with ADLH 5-6 OR 39.05 (36/60-41.88) were most likely to follow a minimal or no decline trajectory. Results of this study further highlight the heterogeneity of health trajectory among residents in LTC setting, re-affirming the need for personalized care. The study shows who among residents would be most at risk for different levels of functional decline.The study findings provide useful information that would assist both immediate and advanced care planning as well as to forecast care personnel requirements into the future based on total acuity levels of residents.

Test-retest variability of mesopic microperimetry-associated parameters in patients with retinitis pigmentosa: REPEAT Study Report No. 2.

Understanding test-retest variability (TRV) of mesopic microperimetry is critical for defining meaningful treatment effects in retinitis pigmentosa (RP) trials. This study uniquely evaluates intra- and intervisit TRV and coefficients of repeatability (CoRs) for microperimetry parameters in RP patients with varying best-corrected visual acuity (BCVA) levels. In this single-centre prospective cohort study, RP patients were assessed on two visits, 14.0 days apart. Patients were grouped by BCVA: low (≤20/50 Snellen; ≥0.4 logMAR) or moderate (>20/50 Snellen; <0.4 logMAR). Using Bland-Altman analyses, the CoRs for intra- and intervisit variability were determined for pointwise (dB), mean (dB), and volume sensitivity (dB*deg2) on mesopic microperimetry. Intravisit CoRs for mean, volume, and pointwise sensitivity were 1.7 dB, 353.2 dB*deg2, and 8.6 dB, respectively, in the low-BCVA group (n = 32), and 0.9 dB, 254.5 dB*deg2, and 7.3 dB in the moderate-BCVA group (n = 15). Intervisit CoRs for mean, volume, and pointwise sensitivity were 2.4 dB, 355.2 dB*deg2, and 10.2 dB in the low-BCVA group (n = 31). The moderate-BCVA group (n = 16) showed smaller CoRs of 1.6 dB, 386.8 dB*deg2, and 7.7 dB for mean, volume, and pointwise sensitivity. BCVA and mean sensitivity, but not fixation stability, are predictors of TRV for volume sensitivity. Due to significant TRV, pointwise sensitivity is an unreliable endpoint for RP patients, irrespective of BCVA. Mean sensitivity is suitable as an endpoint when BCVA is relatively preserved. Volume sensitivity provides additional spatial information, and shows promise as a clinical endpoint for assessing macular sensitivity changes on mesopic microperimetry in patients with RP.

Effects of opening a vertical care area on emergency medicine resident clinical experience.

Challenging clinical environments faced by emergency departments (EDs) have led to operational changes including implementation of vertical care units and fast-track units. Little is known regarding the impact of such units on resident physician clinical education. A retrospective, observational study was performed at an urban quaternary care ED evaluating the effect of opening a vertical care unit with a triage physician directing lower acuity patients to be seen by physician associates (PAs)/advanced practice registered nurses (APRNs) on the following parameters: (1) percentage of patients seen by residents, (2) Emergency Severity Index (ESI) of patients seen by residents, (3) number of procedures performed by residents, (4) number of patients per shift seen by residents, (5) percentage of critical care patients seen by residents, and (6) percentage of behavioral health patients seen by residents. Comparing the implementation of the vertical care unit to the prior 3 months, postgraduate year (PGY)-1 residents had greater exposure to ESI Levels 1 and 2 (odds ratio [OR] 2.15) and more critical care (OR 2.58). PGY-2 and PGY-3 residents had a lower exposure to ESI 1 and 2 patients (PGY-2 OR 0.63, PGY-3 OR 0.61) and less critical care exposure (OR 0.64 for PGY-2 and OR 0.62 for PGY-3) after implementation. PGY-1 residents saw fewer behavioral health patients (OR 0.65) while the other two classes saw more (PGY-2 OR 1.64, PGY-3 OR 2.74). ESI 4 and 5 exposure decreased for all classes (PGY-1 OR 0.15, PGY-2 OR 0.86, PGY-3 OR 0.72). No significant difference was found in the proportion of patients treated by residents (p = 0.85) or the number of procedures performed by residents (p = 0.25) comparing the implementation of a vertical care unit to the prior 3 months. This study suggests no detrimental effects of vertical care unit implementation on multiple resident education outcomes including the number and acuity level of patients seen as well as procedure numbers of resident trainees. While the outcomes measured did not show significant negative effect for the resident compliment as a whole, we noted changes to the distribution of patient acuity based on PGY level. Similar assessments are recommended to determine the educational impact of comparable operational changes in other EDs.

Predictive factors of long-term visual outcomes after primary Descemet's membrane endothelial keratoplasty (DMEK): retrospective study.

To determine predictive factors of higher levels of best-corrected visual acuity (BCVA) in the long-term after primary Descemet's membrane endothelial keratoplasty (DMEK). Retrospective, single-surgeon case series of 129 successful primary DMEK eyes without graft failure and with a minimum postoperative follow-up of 12months. Mixed effect model for repeated measurements (MMRM) analysis was performed to determine recipient, donor, surgical and postoperative factors associated with BCVA ≤ 0.10 logMAR (≥ 20/25 Snellen). After primary DMEK, there was a statistically significant improvement in BCVA with a global reduction in logMAR BCVA (p < 0.00001). There was also a global tendency towards increasing proportion of eyes with BCVA ≤ 0.10 logMAR at all time points (p < 0.00001), from 1.6% before DMEK to 64.4% in eyes with more than 5years of F-U. Absence of retinal disease was associated with a decrease of 0.10 logMAR in postoperative BCVA after primary DMEK, maintaining constant the rest of variables (p < 0.001). The variables age (OR 0.960), postoperative time (OR 1.083), preoperative BCVA ≥ 0.375 logMAR (OR 0.162) and indication for DMEK (OR 5.412) were included in the predictive MMRM model of BCVA ≤ 0.10 logMAR. Primary DMEK is associated with statistically and clinically significant improvement in BCVA that occur early in the postoperative period and are continuous over time. Eyes with retinal comorbidities have increased risk of worse postoperative BCVA after DMEK. Younger recipient age, Fuchs' dystrophy eyes and eyes with better preoperative BCVA are more likely to achieve postoperative BCVA ≤ 0.10 logMAR.

A National Study on the Association of Abdominal Ultrasound with CT Utilization and Disposition in the Emergency Department

Background Ultrasound and CT imaging have distinct and overlapping roles in the assessment of undifferentiated abdominal pain in the emergency department (ED). CT imaging is the gold standard for many pathologies, ranging from bowel obstruction to aortic pathology whereas ultrasound benefits from less radiation exposure and the ability to employ at bedside. In this pilot study, we utilize nationally representative data to identify associations between ultrasound use in ED patients with a primary complaint of abdominal pain with abdominal CT imaging use and disposition. Methods We analyzed retrospective, cross-sectional data on ED patient visits obtained from the National Hospital Ambulatory Medical Care Survey from 2016-2020. This dataset utilizes a weighed multistage, probability sample of ED patient visits involving a four-stage sampling design, including data at county-level geographic regions, hospitals within these regions, emergency service areas in these hospitals, and patient visit records. The study population includes adult patient ED visits with an age of 18 and up presenting with a primary complaint of atraumatic abdominal pain. Descriptive statistics was utilized to describe the sample population. Survey-weighted multivariate logistic regression analysis with calculated odds ratios evaluated for differences between the binary dependent variable of abdominal pain visits with versus without ultrasound use with independent variables of disposition and abdominal CT imaging use while controlling for visit acuity and adjusting for demographic information. Results A total of 7563 patient visits met inclusion criteria, representing approximately 60 million patient visits from 2016-2020. In this study population, 18.5% of visits involved ultrasound, whereas 39.8% of visits involved CT imaging use. 14.6% of visits resulted in hospital admission. On weight-adjusted regression analysis, visits involving ultrasound were less likely to require CT imaging and more likely to be admitted, with ORs of 0.49 (95% CI: 0.37, 0.64) and 1.97 (95% CI: 1.44, 2.68), respectively. Visits involving ultrasound were more likely to be associated with an emergency medicine residency program and an emergent acuity level, with ORs of 1.40 (95% CI: 1.01, 1.94) and 1.53 (95% CI: 1.01, 2.31), respectively. Conclusion In this national pilot study, abdominal pain visits involving ultrasound were associated with a lower likelihood of CT imaging use and a highly likelihood admission and an emergent acuity level.

Time to recovery following cataract surgery and its predictors among patients undergoing surgery at two selected Public Hospitals in Hawassa, Sidama, Ethiopia.

Cataract surgery is a commonly performed procedure aimed at restoring vision in individuals affected by cataracts. The duration of recovery following cataract surgery can vary among patients and is influenced by a multitude of factors. Therefore, the purpose of this study was to determine the time to recovery from cataracts and its predictors among patients treated with cataract surgery at two selected Public Hospitals in Hawassa, Sidama regional state, Ethiopia. Institution-based retrospective cohort study was conducted among 444 cataract patients treated with surgery from January 01, 2019, to December 30, 2021. A simple random sampling method was used to select two public hospitals. The data was collected using Kobo toolbox Version 4 and trained data collectors. STATA Version 16 was used for analysis. To estimate the recovery time and compare survival probability among variables Kaplan-Meir curve and Log-rank test were used. The cox-Proportional hazards model was used to identify significant predictors of time to recovery. The association was reported using the adjusted hazards ratio (AHR) with a 95% confidence interval (95%CI), and the significance level was set at a p-value of 0.05. This study showed that 76.14% of cataract patients recovered from cataracts. The average time taken to recover from a cataract was 30 weeks (IQR = 15 to 48) 95%, CI, (26-33). Age 40-60 years (AHR = 2.04 CI; 1.12-3.82), urban dwellers (AHR = 1.48; 95% CI, 1.13-1.93), medium/high level of visual acuity (AHR = 1.49 CI; 1.14-1.94), secondary cataract (AHR = 1.56 CI; 1.11-2.18) and traumatic cataract (AHR = 1.82 CI; 1.32-2.52) were associated with time to recovery of cataract patients. According to this study, the time to recovery of cataract patients was slightly high. Cataract patients' time to recovery was affected by age, residence, pre-operative visual acuity, presence of diabetes mellitus, and post-operative complications. To improve recovery time of cataract patients, treatment strategies must be prioritized.
