Comparison of electronic versus phone-based administration of the Quality of Recovery-40 survey after ambulatory surgery.

STUDY OBJECTIVE: Studies that track patient-centered outcomes are better suited to evaluate the relative benefits and harms of an intervention in ambulatory surgery as severe morbidity and mortality have become increasingly rare. This pilot study aimed to assess for differences in response rate and survey scores for phone-based and electronic administration of the Quality of Recovery-40 (QoR-40) survey in patients undergoing general anesthesia for ambulatory surgery. DESIGN: A single-center prospective observational study. SETTING: Yale New Haven Hospital (September 22-November 2, 2021). PATIENTS: 100 consecutive patients undergoing ambulatory surgery under general anesthesia. INTERVENTIONS: Patients were randomized to receive QoR-40 surveys via email or phone. MEASUREMENTS: The QoR-40 survey is a 40-item questionnaire that provides a global score across five dimensions: patient support, comfort, emotions, physical independence, and pain. The primary outcome was the response rate following the administration of the QoR-40 survey on postoperative days 1, 2, and 7. The secondary outcome was the mean QoR-40 score during the study period. MAIN RESULTS: A total of 109 patients consented to participate and 100 patients were randomized in this study. A total of 76%, 72%, and 68% of patients completed the survey on POD 1, 2, and 7, respectively. There were no differences in the response rate of patients who completed the survey between phone (78%) versus electronic (74%) administration (difference 4%, 95% confidence interval (CI): -13%, 21%, respectively) on POD 1, 2 (74% vs 70%, difference 4%, 95% CI -14%, 22%, respectively) or 7 (68% vs 68%, difference 0%, 95% CI -18%, 18%, respectively). The mean (standard deviation) QoR-40 score was 176.2 (18.1), 179.8 (19.4), 187.7 (13.1) on POD 1, 2, and 7, respectively. There were no significant differences in the mean QoR-40 scores between groups at any of the time points. CONCLUSION: The response rate following the electronic administration of the QoR-40 survey did not differ from the phone-based administration during the postoperative period following ambulatory surgery. The use of an electronic version of the survey may allow for larger sample sizes with fewer resources utilized in future interventional studies.

Sequelae of Eating Disorders at Imaging.

Although eating disorders are common, they tend to be underdiagnosed and undertreated because social stigma tends to make patients less likely to seek medical attention and less compliant with medical treatment. Diagnosis is crucial because these disorders can affect any organ system and are associated with the highest mortality rate of any psychiatric disorder. Because of this, imaging findings, when recognized, can be vital to the diagnosis and management of eating disorders and their related complications. The authors familiarize the radiologist with the pathophysiology and sequelae of eating disorders and provide an overview of the related imaging findings. Some imaging findings associated with eating disorders are nonspecific, and others are subtle. The presence of these findings should alert the radiologist to correlate them with the patient's medical history and laboratory results and the clinical team's findings at the physical examination. The combination of these findings may suggest a diagnosis that might otherwise be missed. Topics addressed include (a) the pathophysiology of eating disorders, (b) the clinical presentation of patients with eating disorders and their medical complications and sequelae, (c) the imaging features associated with common and uncommon sequelae of eating disorders, (d) an overview of management and treatment of eating disorders, and (e) conditions that can mimic eating disorders (eg, substance abuse, medically induced eating disorders, and malnourishment in patients with cancer).

Diagnostic Accuracy of Shear-Wave Elastography for Breast Lesion Characterization in Women: A Systematic Review and Meta-Analysis.

PURPOSE: The aim of this study was to assess the diagnostic accuracy of 2-D shear-wave elastography (SWE) for differentiating benign and malignant breast lesions in women with abnormal findings on mammography. METHODS: Included in this review are studies of diagnostic accuracy published before June 2021 using 2-D SWE to evaluate female breast lesions. Included studies were required to include at least 50 lesions, report quantitative shear-wave speed (SWS) thresholds, and include a reference standard of either biopsy or 2-year stability. Included studies used the mean, maximum, minimum, or SD of SWS for classification. A systematic search of PubMed, Scopus, Embase, Ovid-MEDLINE, the Cochrane Library, and Web of Science was performed. Bias and applicability of the studies were assessed using Quality Assessment of Diagnostic Accuracy Studies 2. A hierarchical summary receiver operating characteristic model was used to arrive at the summary statistics. RESULTS: Eighty-seven prospective and retrospective studies were included, encompassing 17,810 women (mean age 42.3 ± 10.4 years) with 19,043 lesions (7,623 malignant). Summary sensitivities and specificities, respectively, were 0.86 (95% confidence interval [CI], 0.83-0.88) and 0.87 (95% CI, 0.84-0.88) for mean SWS, 0.83 (95% CI, 0.80-0.85) and 0.88 (95% CI, 0.86-0.90) for the maximum, 0.86 (95% CI, 0.74-0.93) and 0.81 (95% CI, 0.69-0.89) for the minimum, and 0.82 (95% CI, 0.77-0.86) and 0.88 (95% CI, 0.85-0.91) for the SD. Alternatively, the areas under the receiver operating characteristic curve were 0.93 (95% CI, 0.91-0.94), 0.92 (95% CI, 0.90-0.94), 0.90 (95% CI, 0.82-0.96), and 0.92 (95% CI, 0.88-0.94), respectively. CONCLUSIONS: This review demonstrates the discriminative power of SWE in the diagnosis of breast cancer. Using the resulting likelihood ratios, SWE may prove beneficial in downgrading BI-RADS® 4a or upgrading BI-RADS 3 lesions. However, current society guidelines do not provide definitive recommendations regarding the use of SWE and its counterpart strain elastography (SE). Comparison with our results suggests that SE alone or a combination of SE and SWE may provide better diagnostic performance than SWE alone and serve as an adjunct to current diagnostic techniques.

User feedback on usefulness and accessibility features of mobile applications by people with visual impairment.

Purpose: This study aimed at compiling a catalog of mobile applications with accessibility features. The results are expected to provide useful insight into its usage in daily life. Methods: This study was conducted at the Institute for Vision Rehabilitation, Hyderabad in two steps. In step one 57 potentials mobile applications that were useful for persons with visual impairment were identified. In step two, these were explored by 15 participants and their feedback was analyzed through SPSS statistical package. Results: Fifteen mobile users who are visually impaired took part in the study whose mean age was 22 years. A total of 57 mobile applications were explored and rated as per the user's feedback on its usage and accessibility features. Overall rating of general applications ranged from 2.3 to 4.55 and the rating of exclusive applications designed for visually impaired ranged from 2.8 to 4.8. Compilation of catalog of mobile assistive software and its usage through the data generated from this study provides important information to the early mobile users with visual impairment. The built-in accessibility features of the apps that were originally developed for the general population is the constructive move by the app developers towards inclusion. The same should be reinforced that henceforth all-new applications to be accessible for people with disabilities to the standard prescribed by the Web Content Accessibility Guidelines. Conclusion: Mobile technology is a real boon to persons with visual impairment in enhancing their independence. The catalog on accessible mobile applications developed through this study is a valuable tool in providing information on a wider collection of apps to new mobile users.
