Videoconferencing psychotherapy: a systematic review.

Individuals with mental health problems may face barriers to accessing effective psychotherapies. Videoconferencing technology, which allows audio and video information to be shared concurrently across geographical distances, offers an alternative that may improve access. We conducted a systematic literature review of the use of videoconferencing psychotherapy (VCP), designed to address 10 specific questions, including therapeutic types/formats that have been implemented, the populations with which VCP is being used, the number and types of publications related to VCP, and available satisfaction, feasibility, and outcome data related to VCP. After electronic searches and reviews of reference lists, 821 potential articles were identified, and 65 were selected for inclusion. The results indicate that VCP is feasible, has been used in a variety of therapeutic formats and with diverse populations, is generally associated with good user satisfaction, and is found to have similar clinical outcomes to traditional face-to-face psychotherapy. Although the number of articles being published on VCP has increased in recent years, there remains a need for additional large-scale clinical trials to further assess the efficacy and effectiveness of VCP.

Patient satisfaction with physician-patient communication during telemedicine.

The quality of physician-patient communication is a critical factor in treatment outcomes and patient satisfaction with care. To date, few studies have specifically conducted an in-depth evaluation of the effect of telemedicine (TM) on physician-patient communication in a medical setting. Our objective was to determine whether physical separation and technology used during TM have a negative effect on physician-patient communication. In this noninferiority randomized clinical trial, patients were randomized to receive a single consultation with one of 9 physicians, either in person (IP) or via TM. Patients (n = 221) were recruited from pulmonary, endocrine, and rheumatology clinics at a Midwestern Veterans Administration hospital. Physician-patient communication was measured using a validated self-report questionnaire consisting of 33 items measuring satisfaction with visit convenience and physicians patient-centered communication, clinical competence, and interpersonal skills. Satisfaction for physicians patient-centered communication was similar for both consultation types (TM = 3.76 versus IP = 3.61), and noninferiority of TM was confirmed (noninferiority t-test p = 0.002). Patient satisfaction with physicians clinical competence (TM = 4.63 versus IP = 4.52) and physicians interpersonal skills (TM = 4.79 versus IP = 4.74) were similar, and noninferiority of TM was confirmed (noninferiority t-test p = 0.006 and p = 0.04, respectively). Patients reported greater satisfaction with convenience for TM as compared to IP consultations (TM = 4.41 versus IP = 2.37, noninferiority t-test p < 0.001). Patients were equally satisfied with physicians ability to develop rapport, use shared decision making, and promote patient-centered communication during TM and IP consultations. Our data suggest that, despite physical separation, physician-patient communication during TM is not inferior to communication during IP consultations.

Is antibiotic prophylaxis for bacterial endocarditis cost-effective?

Background . Antibiotic prophylaxis for bacterial endocarditis is recommended by the American Heart Association (AHA) before undergoing certain dental procedures. Whether such antibiotic prophylaxis is cost-effective is not clear. The authors’ objective is to estimate the cost-effectiveness of predental antibiotic prophylaxis in patients with underlying heart disease. Methods . The authors conducted a cost-effectiveness analysis using a Markov model to compare cost-effectiveness of 7 antibiotic regimens per AHA guidelines and a no prophylaxis strategy. The study population consisted of a hypothetical cohort of 10 million patients with either a high or moderate risk for developing endocarditis. Results . Prophylaxis for patients with moderate or high risk for endocarditis cost

Child Physical Abuse Prevalence, Characteristics, Predictors, and Beliefs About Parent-Child Violence in South Asian, Middle Eastern, East Asian, and Latina Women in the United States

88,007/quality-adjusted life years saved if clarithromycin was used. Prophylaxis with amoxicillin and ampicillin resulted in a net loss of lives. All other regimens were less cost-effective than clarithromycin. For 10 million persons, clarithromycin prophylaxis prevented 119 endocarditis cases and saved 19 lives. Conclusion . Predental antibiotic prophylaxis is cost-effective only for persons with moderate or high risk of developing endocarditis. Contrary to current recommendations, our data demonstrate that amoxicillin and ampicillin are not cost-effective and should not be considered the agents of choice. Clarithromycin should be considered the drug of choice and cephalexin as an alternative drug of choice. The current published guidelines and recommendations should be revised.

Pulmonary telemedicine—A model to access the subspecialist services in underserved rural areas

The present study examined the prevalence, characteristics, beliefs, and demographic predictors of parent-child physical violence among South Asian, Middle Eastern, East Asian, and Latina women in the United States. Two hundred fifty-one college-educated women from a middle to high SES (South Asian/Middle Eastern, n = 93; East Asian,n = 72; Latina,n = 86) completed a self-report survey on childhood experiences and beliefs regarding physical abuse. Seventy-three percent of the South Asian and Middle Eastern sample, 65% of the East Asian sample, and 78% of the Latina sample reported experiencing at least one type of physical abuse. Significant differences in characteristics and perpetrators of abuse were found across groups. Demographic factors did not predict physical abuse. Experiencing physical abuse was the only predictor for acceptance of physical discipline and as a parental privilege or right across groups. Implications of alternate cultural models of family violence based on beliefs and exposure to violence are discussed.

An Evaluation of Patient-Physician Communication Style During Telemedicine Consultations

BACKGROUND To describe the use of videoconference telemedicine for providing outpatient pulmonary consultation to a remote, underserved clinic site. METHODS Analysis of data from the Milwaukee Veteran Affairs Medical Center (VAMC) pulmonary telemedicine clinic. Pulmonary physicians at the Milwaukee VAMC provide outpatient consultations with the use of videoconference technology to patients located at the Iron Mountain VAMC in Iron Mountain, MI (346 km or 215 miles from Milwaukee). Data on demographics, referral patterns, access to care, consultation process, and outcomes are presented. RESULTS A total of 314 patients (684 visits) received telemedicine consultations between January 1, 1998 and December 31, 2004. Common reasons for referral were abnormal radiology (38%), chronic obstructive pulmonary disease (COPD) (26%), and dyspnea (13%). Physical exam was performed by the telemedicine registered nurse or respiratory therapists in 90% of visits. Common diagnoses were COPD (29%), benign pulmonary nodule (11%), bronchial asthma (6%), and lung cancer (6%). Telemedicine consultation resulted in a change in management for 41% of patients. Only 8% of patients required an in-person clinic visit at Milwaukee VAMC following a telemedicine visit. Telemedicine saved patients 473,340 km or 294,120 miles of travel over the study period. CONCLUSIONS The provision of subspecialty services using telemedicine to a remote underserved rural population provides improved patient access to subspecialty care. Physicians are able to rely on medical history and radiology to manage patients across a broad spectrum of complex pulmonary conditions with the assistance of a non-physician health care provider at the remote site.

pSCANNER: patient-centered Scalable National Network for Effectiveness Research

Background The quality of physician-patient communication is a critical factor influencing treatment outcomes and patient satisfaction with care. To date, there is little research to document the effect of telemedicine (TM) on physician-patient communication. Objective The objectives of this study are to measure and describe verbal and nonverbal communication during clinical TM consultations and to compare TM with in-person (IP) consultations in terms of the quality of physician-patient communication. Methods Veteran patients (n = 19) requiring pulmonary medicine consultations were enrolled into the study. The study group included 11 patients from the Iron Mountain Veterans Affairs Hospital (VAMC) remote site. Patients had individual TM consultations with a pulmonary physician at the Milwaukee VAMC hub site. A control group of 8 patients had IP consultations with a pulmonary physician at the Milwaukee VAMC. Video recordings of medical consultations were coded for patient-physician verbal and nonverbal communication patterns using the Roter Interaction Analysis System (RIAS). Results There were no differences in the length of TM consultations (22.2 minutes) and IP consultations (21.9 minutes). Analysis of visit dialogue indicated that the ratio of physician to patient talk was 1.45 for TM and 1.13 for IP consultations, indicating physician verbal dominance. Physicians were more likely to use orientation statements during IP consultations (P = .047). There were greater requests for repetition from patients during TM consultations (P = .034), indicating perceptual difficulties. Conclusions The study findings indicate differences between TM and IP consultations in terms of physician-patient communication style. Results suggest that, when comparing TM and IP consultations in terms of physician-patient communication, TM visits are more physician centered, with the physician controlling the dialogue and the patient taking a relatively passive role. Further research is needed to determine whether these differences are significant and whether they have relevance in terms of health outcomes and patient satisfaction with care.

Linking clinic and home: a randomized, controlled clinical effectiveness trial of real-time, wireless blood pressure monitoring for older patients with kidney disease and hypertension

This article describes the patient-centered Scalable National Network for Effectiveness Research (pSCANNER), which is part of the recently formed PCORnet, a national network composed of learning healthcare systems and patient-powered research networks funded by the Patient Centered Outcomes Research Institute (PCORI). It is designed to be a stakeholder-governed federated network that uses a distributed architecture to integrate data from three existing networks covering over 21 million patients in all 50 states: (1) VA Informatics and Computing Infrastructure (VINCI), with data from Veteran Health Administrations 151 inpatient and 909 ambulatory care and community-based outpatient clinics; (2) the University of California Research exchange (UC-ReX) network, with data from UC Davis, Irvine, Los Angeles, San Francisco, and San Diego; and (3) SCANNER, a consortium of UCSD, Tennessee VA, and three federally qualified health systems in the Los Angeles area supplemented with claims and health information exchange data, led by the University of Southern California. Initial use cases will focus on three conditions: (1) congestive heart failure; (2) Kawasaki disease; (3) obesity. Stakeholders, such as patients, clinicians, and health service researchers, will be engaged to prioritize research questions to be answered through the network. We will use a privacy-preserving distributed computation model with synchronous and asynchronous modes. The distributed system will be based on a common data model that allows the construction and evaluation of distributed multivariate models for a variety of statistical analyses.

LAB-IN-A-BOX: semi-automatic tracking of activity in the medical office

ObjectiveOlder adults with chronic kidney disease have a high rate of uncontrolled hypertension. Home monitoring of blood pressure (BP) is an integral part of management, but requires that patients bring records to clinic visits. Telemonitoring interventions, however, have not targeted older, less technologically-skilled populations. MethodsVeterans with stage 3 or greater chronic kidney disease and uncontrolled hypertension were randomized to a novel telemonitoring device pairing a Bluetooth-enabled BP cuff with an Internet-enabled hub, which wirelessly transmitted readings (n=28), or usual care (n=15). Home recordings were reviewed weekly and telemonitoring participants were contacted if BP was above goal. The prespecified primary endpoints were improved data exchange and device acceptability. Secondary endpoint was BP change. ResultsForty-three participants (average age 68 years, 75% white) completed the 6-month study. Average start-of-study BP was 147/78 mmHg. Those in the intervention arm had a median of 29 (IQR 22, 53) transmitted BP readings per month, with 78% continuing to use the device regularly, whereas only 20% of those in the usual care group brought readings to in-person visits. The median number of telephone contacts triggered by the wireless monitoring was 2 (IQR 1, 4) per patient. Both groups had a significant improvement in systolic BP (P<0.05, for both changes); systolic BP fell a median of 13 mmHg in monitored participants compared with 8.5 mmHg in usual care participants (P for comparison 0.31). ConclusionThis low-cost wireless monitoring strategy led to greater sharing of data between patients and clinic and produced a trend toward improvements in BP control over usual care at 6 months.

Lessons learned from studies of psychotherapy for posttraumatic stress disorder via video teleconferencing.

Patient-centered healthcare and increased efficiency are major goals of modern medicine, and physician–patient interaction and communication are a cornerstone of clinical encounters. The introduction of the electronic health record (EHR) has been a key component in shaping not only organization, clinical workflow and ultimately physicians’ clinical decision making, but also patient–physician communication in the medical office. In order to inform the design of future EHR interfaces and assess their impact on patient-centered healthcare, designers and researchers must understand the multimodal nature of the complex physician–patient–EHR system interaction. However, characterizing multimodal activity is difficult and expensive, often requiring manual coding of hours of video data. We present our Lab-in-a-Box solution that enables the capture of multimodal activity in real-world settings. We focus here on the medical office where our Lab-in-a-Box system exploits a range of sensors to track computer-based activity, speech interaction, visual attention and body movements, and automatically synchronize and segment this data. The fusion of multiple sensors allows us to derive initial activity segmentation and to visualize it for further interactive analysis. By empowering researchers with cutting-edge data collection tools and accelerating analysis of multimodal activity in the medical office, our Lab-in-a-Box has the potential to uncover important insights and inform the next generation of Health IT systems.
