Context in care--requirements for mobile context-aware patient charts.

The hospital ward is a highly dynamic work environment, in which healthcare personnel rapidly switch from one task to another. The process is partly planned, and partly driven by events and interrupts. A mobile electronic patient chart (MEPC) will be an important tool for supporting order entry and accessing, communicating, and recording clinical information. The users need to switch from one context to another with minimal delay and effort. Context-awareness, the ability to sense relevant situational information, can allow the user interface of the MEPC to adapt to various situations. In this paper, we present a future scenario from the coronary care unit. This scenario is analyzed and discussed in order to develop requirements for design methods, context models, and system properties of the MEPC.

Dear diary, is plastic better than paper? I can't remember: Comment on Green, Rafaeli, Bolger, Shrout, and Reis (2006).

In this commentary, the authors discuss the implications of A. S. Green, E. Rafaeli, N. Bolger, P. E. Shrout, and H. T. Reis's (2006) diary studies with respect to memory. Researchers must take 2 issues into account when determining whether paper-and-pencil or handheld electronic diaries gather more trustworthy data. The first issue is a matter of prospective memory, and the second is a matter of reconstructive memory. The authors review the research on these issues and conclude that regardless of the type of diary researchers use, several factors can conspire to produce prompt--but inaccurate--data.

XML-based synchronization of mobile medical devices.

Today, mobile computing provides enough resources to be used in medical applications. Patient treatment is a process that involves multiple partners. All those partners need access to common patient-data and need to make changes to the patients' health record. Therefore, data that the partners collect and change with mobile devices has to be synchronized on a central server to form the master patient record. Data conflicts resulting from the synchronization have to be solved automatically. Our project describes a solution for XML-based data replication and synchronization for mobile health applications.

Development and comparison of user acceptance of advanced comprehensive triage PDA support system with a traditional terminal alternative system.

An advanced PDA support system for the triage was designed to evaluate users inverted exclamation mark | acceptance of this system compared with a traditional terminal system. Davis inverted exclamation mark | Technology Acceptance Model was used to evaluate users inverted exclamation mark | acceptance. All 72 ER nurses in a 2700-bed medical center were invited for the study. The results showed that the PDA system was easier to operate than the terminal one, but had worse interface. The subjects showed significantly greater willingness to accept the terminal system instead of the PDA system. The comparative acceptance of PDA, compared with that of the old system, might still be marginally too low if its interface couldn inverted exclamation mark |t be improved or no other unique practical benefits could be verified.

Using digital videos displayed on personal digital assistants (PDAs) to enhance patient education in clinical settings.

OBJECTIVES: To evaluate the effects of using an audiovisual animation (i.e., digital video) displayed on a personal digital assistant (PDA) for patient education in a clinical setting. METHODS: Quasi-experimental study of a prospective technology intervention conducted in an outpatient infectious diseases clinic at an academic medical center. Subjects responded to questions immediately before, immediately after, and 4-6 weeks after watching a digital video on a PDA. Outcome measures include participant knowledge of disease, knowledge of medications, and knowledge of adherence behaviors; attitudes toward the video and PDA; self-reported adherence; and practicality of the intervention. RESULTS: Fifty-one English-speaking adults who were initiating or taking medications for the treatment of HIV/AIDS participated in the study. At visit one, statistically significant improvements in knowledge of disease (p<0.005; paired t-test), knowledge of medications (p<0.005; paired t-test), and knowledge of adherence behaviors (p<0.05; ANOVA) were measured after participants watched the PDA-based video. At visit two (4-6 weeks later), statistically significant improvements in self-reported adherence to the medication regimens (p<0.005; paired t-test) were reported. Participants liked the PDA-based video and indicated that it was an appropriate medium for learning, regardless of their baseline literacy skills. The video education process was estimated to take 25 min of participant time and was viewed in both private and semi-private locations. CONCLUSIONS: Technology-assisted education using a digital video delivered via PDA is a convenient and potentially powerful way to deliver health messages. The intervention was implemented efficiently with participants of a variety of ages and educational levels, and in a range of locations within clinical environments. Additional study of this methodology is warranted.

Evaluation of an application for making palmtop computers accessible to individuals with intellectual disabilities.

BACKGROUND: Palmtop computers provide a promising mobile platform to address barriers to computer-based supports for people with intellectual disabilities. This study evaluated a specially designed interface to make navigation and features of palmtop computers more accessible to users with intellectual disabilities. METHOD: The specialised cognitively accessible interface was compared with a standard Windows CE interface. Participants completed a structured set of navigation/computer use tasks using both the experimental and control conditions. Measurements included the amount of assistance needed and errors made in completing the navigation/computer use tasks. RESULTS: Participants (N = 32) made significantly fewer errors (p<.001) and required significantly fewer prompts (p<.001) while using the specialised software interface compared to the mainstream Windows interface. CONCLUSIONS: The research demonstrates the feasibility of using special software design methods, such as linear program flows, error minimisation and the incorporation of repetition and consistency, to improve access to palmtop computers for individuals with intellectual disabilities. Issues related to designing cognitively accessible interfaces are discussed.

e-Ouch: usability testing of an electronic chronic pain diary for adolescents with arthritis.

OBJECTIVES: The aim of this study was to evaluate the usability of the e-Ouch electronic chronic pain diary in adolescents with juvenile idiopathic arthritis. METHODS: A qualitative usability testing approach with semistructured, audiotaped interviews with two iterative cycles was used. A purposive sample of 10 adolescents per cycle was drawn from a rheumatology clinic in a university-affiliated pediatric tertiary care center. Participants were provided with a brief demonstration of the diary and then asked to use the diary "thinking aloud" to record the pain they experienced: (1) when they woke up that morning, (2) during that afternoon, and (3) from the previous evening. Adolescents were then asked a series of open-ended questions addressing ease of use of the diary. Qualitative thematic analysis was used to generate categories and emerging themes from interview data. RESULTS: All of the adolescents stated the e-Ouch diary was very easy to learn, use, and understand and was satisfying to complete. Participants took less than 9 minutes to complete all three of the diary entries with minimal errors. The usability evaluation revealed aspects of the interface that were suboptimal (eg, VAS slider) and impeded the performance of certain tasks. Adolescents generated ideas on how the diary interface could be improved. CONCLUSIONS: A multifaceted usability approach provided important insight regarding the use of technology by adolescents with arthritis and, more specifically, for understanding how adolescents can more effectively use an electronic chronic pain diary.

MobileMed: a PDA-based mobile clinical information system.

Patient clinical data are distributed and often fragmented in heterogeneous systems, and therefore the need for information integration is a key to reliable patient care. Once the patient data are orderly integrated and readily available, the problems in accessing the distributed patient clinical data, the well-known difficulties of adopting a mobile health information system, are resolved. This paper proposes a mobile clinical information system (MobileMed), which integrates the distributed and fragmented patient data across heterogeneous sources and makes them accessible through mobile devices. The system consists of four main components: a smart interface, an HL7 message server (HMS), a central clinical database (CCDB), and a web server. The smart interface and the HMS work in concert to generate HL7 messages from the existing legacy systems, which essentially send the patient data in HL7 messages to the CCDB to be stored and maintained. The CCDB and the web server enable the physicians to access the integrated up-to-date patient data. By proposing the smart interface approach, we provide a means for effortless implementation and deployment of such systems. Through a performance study, we show that the HMS is reliable yet fast enough to be able to support efficient clinical data communication.

A comparison of delivery methods of cognitive-behavioral therapy for panic disorder: an international multicenter trial.

Cognitive-behavioral therapy (CBT) is the psychological treatment of choice for panic disorder (PD). However, given limited access to CBT, it must be delivered with maximal cost-effectiveness. Previous researchers have found that a brief computer-augmented CBT was as effective as extended therapist-delivered CBT. To test this finding, this study randomly allocated 186 patients with PD across 2 sites in Scotland and Australia to 12 sessions of therapist-delivered CBT (CBT12), 6 sessions of therapist-delivered (CBT6) or computer-augmented CBT (CBT6-CA), or a waitlist control. On a composite measure, at posttreatment, the outcome for CBT 12 was statistically better than the outcome for CBT6. The outcome for CBT6-CA fell between CBT12 and CBT6, but could not be statistically distinguished from either treatment. The active treatments did not differ statistically at 6-month follow-up. The study provided some support for the use of computers as an innovative adjunctive-therapy tool and merits further investigation.

Development and pilot evaluation of user acceptance of advanced mass-gathering emergency medical services PDA support systems.

The support systems for the Emergency Medical Services (EMS) in the mass gatherings, such as the local marathon or the large international baseball games, had been underdeveloped. The purposes for this study were to develop triage-based EMS Personal Digital Assistant (PDA) support systems for the mass-gatherings and to evaluate users' perceived ease of use and usefulness of the systems in terms of Davis' Technology Acceptance Model (TAM). The systems were developed based on an established intelligent triage PDA support system and two other forms-the general EMS form from the Taipei EMT and the customer-made Mass Gathering Medical form used by a medical center. 23 nurses and 6 physicians in the medical center, who had ever served in the mass gatherings, were invited to examine the new systems and answered the TAM questionnaire. The results showed that the PDA systems included as many 450 information items inside 42 screens under 6 categories and the great potential of using triage-based PDA systems in the mass gatherings. Overall, most of the subjects agreed with that the systems were easy to use and useful for the mass gatherings, and they were willing to accept the systems.

Diagnostic accuracy of new handheld echocardiography with Doppler and harmonic imaging properties.

BACKGROUND: The first generation of handheld echocardiography devices was evaluated with divergent results because of inherent technical limitations. New handheld devices with continuous/pulsed wave Doppler and tissue harmonic imaging were introduced recently. In this study, comparisons were drawn among standard echocardiography, invasively measured systolic pulmonary artery pressure, and these new devices. OBJECTIVE: We sought to evaluate new handheld echocardiography and its diagnostic accuracy compared with standard echocardiography. METHODS: Two consecutive echocardiographic examinations were performed by experienced and independent examiners using handheld and standard echocardiography. Systolic pulmonary artery pressure was measured by Swan-Ganz catheter. RESULTS: In all, 177 (56.2%) patients had normal cardiac function; 138 (43.8%) had underlying cardiac pathology. Handheld echocardiography had an overall agreement of 94.8% and kappa of 0.89 to detect the main echocardiographic finding. Handheld echocardiography detected valve disease with an agreement of 96.7% and kappa of 0.93; global left ventricular function was assessed correctly in 85.6% of cases. Pericardial effusion was diagnosed with an agreement of 91.2%. Dyssynergy was found by handheld echocardiography with an agreement of 95.4% and kappa value of 0.88. Systolic pulmonary artery pressure measured by handheld echocardiography and Swan-Ganz catheter had a correlation of 0.97. CONCLUSION: This study demonstrates the high diagnostic accuracy of handheld devices with continuous/pulsed wave Doppler and harmonic imaging, and that these devices broaden the diagnostic spectrum while allowing for enhanced mobility in everyday clinical applications.
