Ambient Data

Abstract Background Registered nurses (RNs) regularly adapt their work to ever-changing situations but routine adaptation transforms into RN strain when service demand exceeds staff capacity and patients are at risk of missed or delayed care. Dynamic monitoring of RN strain could identify when intervention is needed, but comprehensive views of RN work demands are not readily available. Electronic care delivery tools such as nurse call systems produce ambient data that illuminate workplace activity, but little is known about the ability of these data to predict RN strain. Objectives The purpose of this study was to assess the utility of ambient workplace data, defined as time-stamped transaction records and log file data produced by non-electronic health record care delivery tools (e.g., nurse call systems, communication devices), as an information channel for automated sensing of RN strain. Methods In this exploratory retrospective study, ambient data for a 1-year time period were exported from electronic nurse call, medication dispensing, time and attendance, and staff communication systems. Feature sets were derived from these data for supervised machine learning models that classified work shifts by unplanned overtime. Models for three timeframes —8, 10, and 12 hours—were created to assess each model's ability to predict unplanned overtime at various points across the work shift. Results Classification accuracy ranged from 57 to 64% across three analysis timeframes. Accuracy was lowest at 10 hours and highest at shift end. Features with the highest importance include minutes spent using a communication device and percent of medications delivered via a syringe. Conclusion Ambient data streams can serve as information channels that contain signals related to unplanned overtime as a proxy indicator of RN strain as early as 8 hours into a work shift. This study represents an initial step toward enhanced detection of RN strain and proactive prevention of missed or delayed patient care.

The purpose of this mixed methods study was to determine the barriers that special educator teachers encounter when using iPads within the Life Skills classroom. The research investigates the experiences, frustrations, and barriers through educators’ perceptions of iPad implementation. The influence of these issues suggests why iPad usage is not a device that special education classrooms are using in a widespread daily manner. Exploration of iPads as an educational tool and as a communication device is also discussed, along with considerations of other communications systems such as Picture Exchange Communication Systems and Alternative and Augmented Communication Devices is considered. Recommendations for further possible research are also discussed.

Objective Surgical procedures that render patients acutely aphonic can cause them to experience significant anxiety and distress. We queried patient perceptions after tracheostomy or laryngectomy and investigated whether introducing augmentative technology was associated with improvement in patient-reported outcomes. Methods Participants included hospitalized patients who acutely lost the ability to speak due to tracheostomy or total laryngectomy from April 2018 to December 2019. We distributed questions regarding the patient communication experience and relevant questions from the validated V-RQOL questionnaire (Voice-Related Quality of Life). Patients were offered a tablet with the electronic communication application Verbally. Pre- and postintervention groups were compared with chi-square analyses. Results Surveys were completed by 35 patients (n = 18, preintervention; n = 17, postintervention). Prior to using augmentative technology, 89% of patients who were aphonic reported difficulty communicating, specifically noting breathing or suctioning (56%), treatment and discharge plans (78%), or immediate needs, such as pain and using the bathroom (39%). Communication difficulties caused anxiety (55%), depression (44%), or frustration (62%), and 92% of patients were interested in using an electronic communication device. Patients reported less trouble communicating after the intervention versus before (53% vs 89%, P = .03), including less difficulty communicating about treatment or discharge plans (35% vs 78%, P < .01). V-RQOL scores were unchanged. Discussion Acute loss of phonation arising from surgery can be highly distressing for patients, and use of augmentative technology may alleviate some of these challenges by improving communication. Further studies are needed to identify what additional strategies may improve overall well-being. Implications for Practice Electronic communication devices may benefit patients with acute aphonia.

e13582 Background: Cancers of the brain lead to significant neurocognitive, physical and psychological morbidities. Digital technologies provide a novel platform to capture and evaluate these needs. Mobile health (mHealth) applications typically focus on one aspect of care rather than addressing the multimodal needs of the demographic of these patients. The Vinehealth application aims to address this by tracking symptoms, delivering machine learning-based personalised educational content, and facilitating reminders for medications and appointments. Where mHealth interventions traditionally lack the evidence-based approach of pharmaceuticals, this study acts as an initial step in the rigorous assessment of a new digital health tool. Methods: A mixed methodology approach was applied to evaluate the Vinehealth application as a care delivery adjunct. Patients with brain cancer were recruited from the day of their procedure ± 7 days. Over a 12-week period, we collected real-world and ePRO data via the application. We assessed qualitative feedback from mixed-methodology surveys and semi-structured interviews at onboarding and after two weeks of application use. Results: Six participants enrolled of whom four downloaded the application; four completed all interviews. One patient set up their device incorrectly and so couldn't receive the questionnaires; excluding this patient, the EQ-5D-5L and EORTC QLQ-BN20 completion rates were 100% and 83% respectively. Average scores (±SD) at onboarding and offboarding were EQ-5D-5L: 2.07±1.28 and 1.73±1.22, and QLQ-BN20: 13.33 and 22.5. In total: 212 symptoms, 174 activity, and 47 medication data points were captured, and 113 educational articles were read. Participants were generally optimistic about application use. All users stated they would recommend Vinehealth and expressed subjective improvements in care. Accessibility issues in the ePRO delivery system which impacted completion rate were identified and have subsequently been fully addressed. Conclusions: This feasibility study showed acceptable patient use, led to a subjective improvement in care, and demonstrated effective collection of real-world and validated ePRO data. This provides a strong basis to further explore the integration of the Vinehealth application into brain cancer care. This study will inform the design of a larger, more comprehensive trial continuing to evaluate improvements in care delivery through data collection, educational support and patient empowerment.

Background: The Accreditation Council for Graduate Medical Education (ACGME) has defined six core competencies that reflect changing needs of health care delivery. One of these competencies, practice-based learning and improvement (PBLI), is essential for improving processes and outcomes of care. As an initial step, incorporating a standardized method for data collection is required and helps physicians monitor the quality of their work, identify learning and QI needs and positively change practice behavior. Methods: The PINNACLE Registry is an outpatient practice-based QI program designed to optimize quality of care through the standardized collection and reporting of clinical data on CAD, atrial fibrillation, heart failure and hypertension. Twelve cardiac fellows participate in the PINNACLE Registry at St. John Hospital and Medical Center in Detroit. At each clinic encounter, a data collection form (DCF) which captures patient demographics, history/risk factors, and current therapies were recorded and transmitted to the ACC to generate comparative feedback reports about the quality of care delivered to patients. Use of the DCF was piloted from September 2009 through November 2009 and expanded to all patient encounters from December 1, 2009 through January 31, 2010. Impressions from the first 60 encounters are reported. Results: Fellows reported that the DCF improved their knowledge, though the initial process of collecting data impacted clinic workflow. Utilization of the DCF initially resulted in longer patient visits which decreased over time (average 7 minutes reduced to 4 minutes per patient). As a checklist connecting patient workflow to best cardiology evidence, residents reported that diagnostic and therapeutic decisions were not simply monitored, but guided by the DCF. Conclusions: The DCF was found be a useful tool for data collection and clinical decision support. Participation in the PINNACLE Registry has provided the opportunity to further the ACGME core competencies of patient care and practice-based learning and improvement in a cardiology fellow outpatient clinic.

In this work, a new Multiple Input Multiple Output (MIMO) antenna system with a novel shape inspired by nature is proposed for Fifth-Generation (5G) communication systems. The antenna is designed on a Rogers 5880. The dielectric constant of the substrate is 2.2, and the loss tangent is assumed to be 0.0009. The gain of the system for the desired bandwidth is nearly 8 dB. The simulated and the measured efficiency of the proposed system is 95% and 80%, respectively. To demonstrate the capability of the system as a potential candidate for future 5G communication devices, MIMO key performance parameters such as the Envelope Correlation Coefficient (ECC) and Diversity Gain (DG) are computed. It is found that the proposed system has low ECC, constant DG, and high efficiency for the desired bandwidth.

AbstractObjectivesAfter the 2011 Great East Japan Earthquake, the resource utilization of and the problems encountered with communication devices were examined.MethodsA questionnaire survey was submitted to disaster medical assistance teams (DMATs) that were at the primary sites of destruction after the earthquake.ResultsWe collected data from 196 teams. During the first 4 days after the earthquake, the use of mobile phones, laptop computers, and landline phones was rated as poor to moderate, and satisfaction was very low, while satisfaction with satellite phones was rated as good to moderate (50%). The degree of satisfaction continued to increase gradually over time. Satellite phones, however, had several problems: poor reception, line instability, voice call use only, and inability to send large amounts of data.ConclusionsTo ensure effective communication during the acute phase in the aftermath of large disasters, a new satellite communication device is needed that not only is portable, battery powered, and able to send large volumes of data, but also offers stable communication.
