Telemedicine and e-Health

Background: Brazilian registries have shown a gap between evidence-based therapies and real treatments. We aim to compare the use of the pharmacoinvasive strategy and mortality in patients with ST elevation myocardial infarction (STEMI) transferred pre– and post–chest pain protocol with access to telemedicine (CPPT) in a private hospital network. Materials and Methods: A CPPT was implemented in 22 private emergency departments in 2012. Emergency physicians and nurses of all facilities were trained to disseminate the information to comply with a chest pain protocol focusing on reperfusion therapy (pharmacoinvasive strategy) for STEMI. To conduct clinical discussions using telemedicine, a cardiologist from a reference hospital in cardiology (RHC) was available 24 h/day, 7 days/week. Using the database of all consecutive admissions, we compared the data of patients with STEMI transferred to the RHC in 2011 (pre-CPPT) and 2013–2014 (post-CPPT). Results: We included 376 patients (113 pre-CPPT and 263 post-CPPT) with STEMI. All patients admitted in the RHC were transferred from the 22 emergency departments. Comparing pre-CPPT and post-CPPT, we did not find differences regarding age, gender, hypertension, dyslipidemia, diabetes, smoking, previous myocardial infarction, or Killip classification. However, the use of CPPT was associated with a greater use of pharmacoinvasive strategy (55.8% versus 38%; p = 0.002) and a trend toward lower in-hospital mortality (3% versus 8%; p = 0.06). Conclusions: The implementation of a CPPT was associated with a significant increase in the use of pharmacoinvasive strategy in patients with STEMI and a trend toward reduced in-hospital mortality in a private hospital network.

Background: Cardiac rehabilitation can reduce mortality of patients with cardiovascular disease, but a frequently low participation rate in rehabilitation programs has been found globally. The objective of the Teledialog study was to assess the cost-utility (CU) of a cardiac telerehabilitation (CTR) program. The aim of the intervention was to increase the patients' participation in the CTR program. At discharge, an individualized 3-month rehabilitation plan was formulated for each patient. At home, the patients measured their own blood pressure, pulse, weight, and steps taken for 3 months. Materials and Methods: The analysis was carried out together with a randomized controlled trial with 151 patients during 2012–2014. Costs of the intervention were estimated with a health sector perspective following international guidelines for CU. Quality of life was assessed using the 36-Item Short Form Health Survey. Results: The rehabilitation activities were approximately the same in the two groups, but the number of contacts with the physiotherapist was higher among the intervention group. The mean total cost per patient was €1,700 higher in the intervention group. The quality-adjusted life-years (QALYs) gain was higher in the intervention group, but the difference was not statistically significant. The incremental CU ratio was more than €400,000 per QALY gained. Conclusions: Even though the rehabilitation activities increased, the program does not appear to be cost-effective. The intervention itself was not costly (less than €500), and increasing the number of patients may show reduced costs of the devices and make the CTR more cost-effective. Telerehabilitation can increase participation, but the intervention, in its current form, does not appear to be cost-effective.

Objective: To test the functionality and acceptability of a wireless vital sign monitor in an inpatient obstetric unit. Materials and Methods: Pregnant women at a U.S. tertiary-care hospital wore a wireless vital sign sensor that captures heart rate, respiratory rate, and temperature. Measurements were compared with vital signs obtained by standard devices. We defined continuous capture of vital signs for 30 min with wireless data transfer to a central monitor as functional success. Acceptability was assessed per the pregnant women and nurses observing the device. Bland–Altman plots were constructed to assess agreement between the wireless sensor and standard measurements. Results: Thirty of 32 enrolled pregnant women had successful monitoring; 2 cases were stopped early for non–study-related reasons. Comparing wireless sensor and standard measurements, the mean difference (limits of agreement) values at the 25th and 75th percentiles were 1.6 (±13.2) and 4.2 (±18.6) heartbeats/min, 4.2 (±6.1) and 0.7 (±5.4) respirations/min, and 0.02°C (±1.5) and 0.5°C (±1.8), respectively. Most pregnant women found the device comfortable, likeable, and useful (78%, 81%, and 97%, respectively); 80% of nurses found the monitor easy to use, and 84% would recommend it to a patient. Conclusions: We successfully obtained maternal vital signs using a simple wireless monitor with high acceptability. Well-validated monitors of this nature could significantly alleviate the human resource burden of monitoring during labor and confer greatly desired mobility to laboring pregnant women, although incorporation of blood pressure monitoring will be critical.

Background: Many hospitals do not have regular access to psychiatry consult services. This is well understood as a common shortage at nonacademic community hospitals (especially in rural environments, and may also be a problem at noncontiguously located smaller hospitals that are affiliated with academic medical centers in urban settings. The authors sought to deliver timely inpatient psychiatric consultation–liaison services via telemedicine to a local but physically separated hospital affiliated with an academic medical center. Materials and Methods: The authors collaborated with an office dedicated to the advancement of telemedicine technology at their academic medical center. They developed a telemedicine-based care model to deliver inpatient consultation–liaison psychiatry consultations to an affiliated (but physically separate) small academic hospital that did not have its own on-site consultation–liaison psychiatry team. Results: The authors were able to successfully complete 30 consultations, each within 24 h. Only 1 patient was ultimately unwilling to participate in the telemedicine interview. As consultations were accomplished on same day as request, patient length of stay was unaffected. Conclusions: This pilot study suggests that telemedicine is a viable model for inpatient consultation–liaison psychiatry services to hospitals without on-site psychiatry resources and represents a viable alternative model of service delivery.

Background: Major depression is a highly prevalent and severe mental disease. Despite the effective treatment options available, the risk of relapse is high. Interventions based on information and communication technologies generate innovative opportunities to provide support to patients after they completed treatment for depression. Materials and Methods: This acceptability study evaluated the Internet-based program Apoyo, Seguimiento y Cuidado de Enfermedades a partir de Sistemas Operativos (ASCENSO) in terms of its feasibility and acceptability in a sample of 35 patients in Chile. Results: The study reveals high rates of acceptance and satisfaction among patients who actively used the program. As obstacles, patients mentioned technical problems, a lack of contact with other participants, and an insufficient connection between the program and the health service professionals. Conclusions: ASCENSO appears to be a promising complement to regular care for depression. Following improvements of the program based on participants' feedback, future research should evaluate its efficacy and cost-effectiveness.

Background: Systems for range of motion (ROM) measurement such as OptoTrak, Motion Capture, Motion Analysis, Vicon, and Visual 3D are so expensive that they become impracticable in public health systems and even in private rehabilitation clinics. Telerehabilitation is a branch within telemedicine intended to offer ways to increase motor and/or cognitive stimuli, aimed at faster and more effective recovery of given disabilities, and to measure kinematic data such as the improvement in ROM. Materials and Methods: In the development of the RehabGesture tool, we used the gesture recognition sensor Kinect^® (Microsoft, Redmond, WA) and the concepts of Natural User Interface and Open Natural Interaction. Results: RehabGesture can measure and record the ROM during rehabilitation sessions while the user interacts with the virtual reality environment. The software allows the measurement of the ROM (in the coronal plane) from 0° extension to 145° flexion of the elbow joint, as well as from 0° adduction to 180° abduction of the glenohumeral (shoulder) joint, leaving the standing position. The proposed tool has application in the fields of training and physical evaluation of professional and amateur athletes in clubs and gyms and may have application in rehabilitation and physiotherapy clinics for patients with compromised motor abilities. Conclusions: RehabGesture represents a low-cost solution to measure the movement of the upper limbs, as well as to stimulate the process of teaching and learning in disciplines related to the study of human movement, such as kinesiology.

Background: Delivering specialty care remotely directly into people's homes can enhance access for and improve the healthcare of individuals with chronic conditions. However, evidence supporting this approach is limited. Materials and Methods: Connect.Parkinson is a randomized comparative effectiveness study that compares usual care of individuals with Parkinson's disease in the community with usual care augmented by virtual house calls with a Parkinson's disease specialist from 1 of 18 centers nationally. Individuals in the intervention arm receive four virtual visits from a Parkinson's disease specialist over 1 year via secure, Web-based videoconferencing directly into their homes. All study activities, including recruitment, enrollment, and assessments, are conducted remotely. Here we report on interest, feasibility, and barriers to enrollment in this ongoing study. Results: During recruitment, 11,734 individuals visited the study's Web site, and 927 unique individuals submitted electronic interest forms. Two hundred ten individuals from 18 states enrolled in the study from March 2014 to June 2015, and 195 were randomized. Most participants were white (96%) and college educated (73%). Of the randomized participants, 73% had seen a Parkinson's disease specialist within the previous year. Conclusions: Among individuals with Parkinson's disease, national interest in receiving remote specialty care directly into the home is high. Remote enrollment in this care model is feasible but is likely affected by differential access to the Internet.

Purpose: The objective of this study was to design and validate a “Tele-Operated UltRasound System” (“TOURS”) to perform ultrasound examinations on patients located in isolated areas. Materials and Methods: A commercially available portable echograph was modified to allow functions (Doppler, two-dimensional, three-dimensional, elastography, etc.) and settings (gain, depth, freeze, record, etc.) to be teleoperated through an Internet connection. Specialized probes were developed that contained motorized transducers that could be teleoperated to change the transducer orientation. The system was installed and tested in four medical centers 50 km, 60 km, 1,800 km, and 7,000 km away from the university hospital. Results: Using the teleoperated system, 100 examinations were performed on the abdomen and pelvis (36%), vascular structures (42%), and small parts (thyroid and muscle, 22%), and 15 were performed on fetuses. During these examinations the expert sonographer was able to teleoperate the echograph and motorized probe to obtain images of sufficient quality for diagnoses in 97% of the cases. The average time for one examination was 17 ± 4 min. This new system (dimensions of 400 cm³ and weighing 430 g) was found to be more ergonomic that a robotic arm previously developed by us for tele-echography (dimensions of 35 × 40 × 40 cm³ and weighing 3–4 kg). In addition, the teleoperation of the echograph settings and functions allowed for greater ease in acquiring images, resulting in faster examinations with improved quality images. Conclusions: The results of this study demonstrate that the teleoperated echograph and probe system developed by our research group can be successfully used for ultrasound examinations in areas isolated from trained sonographers.

Background: The Apple (Cupertino, CA) HealthKit is a new telemonitoring platform that promises to make it easier for patients and healthcare institutions to collect, transmit, and store data from devices that monitor common conditions such as diabetes, hypertension, and asthma. To assess the potential use for this platform in primary care, we need to know how many Apple Healthkit users there are and if they have conditions that could benefit from telemonitoring. Materials and Methods: We examined patients in the Mayo Clinic primary care practice in Rochester, MN, who registered to connect to their Mayo Clinic medical record with Apple HealthKit. We used the primary care registry to identify users with chronic conditions of diabetes, hypertension, asthma, and depression. We also examined users for recent measurements of blood pressure, glucose, hemoglobin A1C, and cholesterol. Results: Of 98,151 patients there were 503 registrants of HealthKit. There were 95 (19%) who had hypertension, 37 (7.4%) who had diabetes, 125 (25%) who had depression, and 56 (11%) who had asthma. Overall, there were 245 (49%) who had readily telemonitorable conditions. Conclusions: Almost half of primary care Apple HealthKit registrants have conditions that could benefit from telemonitoring. This pre-installed telemonitoring platform, available on every new iPhone^® (Apple), can be used to monitor a significant number of primary care patients. However, it also has continued provider and informatics barriers that need to be addressed.

Purpose: To examine the features and types of health information provided in Chinese diabetes mobile applications (apps) for patients' self-management. Materials and Methods: Through multiple rounds of screening, we identified a total of 95 relevant iOS (Apple, Cupertino, CA) and Android™ (Google, Mountain View, CA) apps and examined each app's features and health information types based on each app's description in the app stores. We used a 15-feature algorithm to evaluate the apps' abilities for supporting diabetic patients' self-management, based on U.S. national standards for diabetes self-management. We also adapted the health information wants framework to analyze the types of information that the apps provided for diabetic patients. Results: Diabetes education was the most common feature, provided by 75% of the apps. Blood glucose checking was enabled by 65% of the apps. Diet management, insulin checking, and physical activity monitoring were enabled by 53%, 49%, and 44% of the apps, respectively. Only a small percentage of the apps enabled psychosocial support (29%) or tracking of blood pressure (14%), cholesterol (14%), or body mass index (11%). None of the apps provided all seven types of information posited by the health information wants framework. Only a small percentage of the apps provided information about psychosocial support (29%), healthcare providers (24%), or healthcare facilities (24%). Information about complementary and alternative medicine was the least likely type of information provided in the apps, with only 7% of the apps providing this type of information. Conclusions: Our findings have important implications for improving the quality of Chinese diabetes mobile apps to facilitate patients' self-management.
