RESUMEN

Background: A picture archiving and communication system (PACS) is a means wherein the images are acquired, displayed, transmitted, and stored digitally. Bone Ninja is an application on iPad (Apple Inc.) on the IOS platform, developed as a teaching tool for deformity corrections around the knee. The principal objective of this study is to determine the reliability and consistency of Bone Ninja application in measuring the preoperative and postoperative alignment in patients undergoing a total knee arthroplasty and compare it with the PACS. Methods: This retrospective cross-sectional study was done using preoperative and postoperative leg-length radiographs of 50 consecutive patients (50 knees) who underwent unilateral total knee arthroplasty. Using Bone Ninja application and PACS, preoperative Lateral Distal Femoral Angle (LDFA), Tibiofemoral Angle (TFA), Medial Proximal Tibial Angle (MPTA) and postoperative Tibial alignment angle (TAA), Tibiofemoral angle (TFA), Femoral alignment angle (FAA) were measured independently by three doctors (two orthopedists and one radiologist). The measurements were repeated after an interval to determine intra and interobserver reliability. Results: Both preoperative (TFA, LDFA, MPTA) and postoperative measurements (TFA, TAA, FAA) showed highly correlated intraobserver and interobserver correlation coefficients. Cohen kappa values for all the measurements were greater than 0.80 but the values were higher for PACS compared to Bone Ninja application. Conclusions: PACS remains the gold standard, but bone ninja application is a reliable alternative for preoperative and postoperative alignment measures in total knee arthroplasty where PACS is not available.

RESUMEN

CLINICAL RELEVANCE: While the clinical focus of performance metrics is traditionally based on visual acuity, research from the field of visual impairment has demonstrated that metrics such as reading speed and critical print size correlate much more strongly with subjective patient reported outcomes and assessed ability in real-world tasks. BACKGROUND: More recently, digital device use has increasingly replaced many paper-based tasks. Therefore, this study aimed to assess the correlation between standard acuity/contrast metrics and functional reading ability compared to real-world performance on an iPad-based reading task with astigmatic patients corrected wearing toric and mean spherical equivalent contact lenses. METHODS: Thirty-four adult participants, with -0.75 to -1.50-D of refractive astigmatism, were enrolled in a double-masked cross-over study and fitted with toric and spherical equivalent contact lenses, in random order. A digital application was developed to assess zoom, contrast modifications, the distance at which the tablet was held, blink rate, and time to complete the reading task. High and low contrast near logMAR visual acuity were measured along with reading performance (critical print size and optimal reading speed). RESULTS: The amount participants chose to increase tablet font size (zoom) was correlated with their high-contrast visual acuity with toric correction (r = 0.434, p = 0.010). With best sphere correction, zoom was associated with reading speed (r = -0.450, p = 0.008) and working distance (r = 0.522, p = 0.002). Text zoom was also associated with horizontal (toric: r = 0.898, p < 0.001; sphere: r = 0.880, p < 0.001) and vertical scrolling (toric: r = 0.857, p < 0.001; sphere: r = 0.846, p < 0.001). There was a significant negative association between the selection of text contrast and zoom (toric: r = -0.417, p = 0.0141; sphere: r = -0.385, p = 0.025). CONCLUSION: Real-world task performance allows more robust assessment of visual function than standard visual metrics alone. Digital technology offers the opportunity to better understand the impact of different vision correction options on real-world task performance.

RESUMEN

With the aging population and consequent increase in associated prevalence of frailty, dementia, and multimorbidity, primary care physicians will be overwhelmed with the complexity of the psychosocial and clinical presentation. Geriatric syndromes including frailty, sarcopenia, cognitive impairment, and anorexia of aging (AA) either in isolation or in combination are associated with an increased risk of adverse outcomes and if recognized early, and appropriately managed, will lead to decreased disability. Primary care practices are often located in residential settings and are in an ideal position to incorporate preventive screening and geriatric assessment with personalized management. However, primary care physicians lack the time, multidisciplinary resources, or skills to conduct geriatric assessment, and the limited number of geriatricians worldwide further complicates the matter. There is no one effective strategy to implement geriatric assessment in primary care which is rapid, cost-effective, and do not require geriatricians. Rapid Geriatric Assessment (RGA) takes <5 min to complete. It screens for frailty, sarcopenia, AA, and cognition with assisted management pathway without the need of a geriatrician. We developed RGA iPad application for screening with assisted management in two primary care practices and explored the feasibility and overall prevalence of frailty, sarcopenia, and AA. The assessment was conducted by trained nurses and coordinators. Among 2,589 older patients ≥65 years old, the prevalence of frailty was 5.9%, pre-frail 31.2%, and robust 62.9%. Fatigue was present in 17.8%, and among them, the prevalence of undiagnosed depression as assessed by the Patient Health Questionnaire (PHQ)-9 was 76.4% and 13.5% of total. The prevalence of sarcopenia was 15.4%, and 13.9% experienced at least one fall in the past year. AA was prevalent in 10.9%. The time taken to do the assessment with defined algorithm was on average 5 min or less per patient, and 96% managed to complete the assessment prior to seeing their doctor in the same session. The RGA app is a rapid and feasible tool to be used by any healthcare professional in primary care for identification of geriatric syndrome with assisted management.

RESUMEN

PURPOSE: The purpose of this study was to evaluate the use of the Engaging Parents in Education for Discharge (ePED) iPad application on parent experiences of hospital discharge teaching and care coordination. Hypotheses were: parents exposed to discharge teaching using ePED will have 1) higher quality of discharge teaching and 2) better care coordination than parents exposed to usual discharge teaching. The secondary purpose examined group differences in the discharge teaching, care coordination, and 30-day readmissions for parents of children with and without a chronic condition. DESIGN/METHODS: Using a quasi-experimental design, ePED was implemented on one inpatient unit (n = 211) and comparison group (n = 184) from a separate unit at a pediatric academic medical center. Patient experience outcome measures collected on day of discharge included Quality of Discharge Teaching Scale-Delivery (QDTS-D) and care coordination measured by Care Transition Measure (CTM). Thirty-day readmission was abstracted from records. RESULTS: Parents taught using ePED reported higher QDTS-D scores than parents without ePED (p = .002). No differences in CTM were found between groups. Correlations between QDTS-D and CTM were small for ePED (r = 0.14, p 0.03) and non-ePED (r = 0.29, p < .001) parent groups. CTM was weakly associated with 30-day readmissions in the ePED group. CONCLUSION: The use of ePED by the discharging nurse enhances parent-reported quality of discharge teaching. PRACTICE IMPLICATIONS: The ePED app is a theory-based structured conversation guide to engage parents in discharge preparation. Nursing implementation of ePED contributes to optimizing the patient/family healthcare experience.

RESUMEN

We describe the development and evaluation of an iPad application to promote knowledge of tobacco risk and cessation resources for pregnant women. Pregnant women completed a survey on tobacco use in pregnancy, and clinicians reviewed their tobacco cessation practices and resources. The women reported that content was easy to understand (98%) and helped them understand tobacco risks (94%). Tobacco users reported that the information helped them want to quit smoking (75%) and provided ideas on how to quit (58%). Clinicians reported themes that reflected ease of use, support of pregnant women, and use of electronic resources. We conclude that iPad applications and other electronic health education delivery methods are useful tools that can augment coordinated and consistent tobacco cessation efforts in clinical settings.
