BACKGROUND The process of manually recording the consumption of medical materials can be time consuming and prone to omission owing to its detailed and complicated nature. Implementing an information system will better improve work performance. see more OBJECTIVE The Information System Success Model was adopted as the theoretical foundation. The opinions of nursing staff were collected to verify the impact of the system intervention on their work performance. METHODS This cross-sectional study was conducted at a regional teaching hospital. Nursing staff were invited to participate in the field survey. A total of 296 questionnaires were collected, and of these, 284 (95.9%) were valid and returned. RESULTS The key findings showed that two critical factors ("subjective norm" and "system quality") had significant positive effects (both P less then .001) on user satisfaction (R2=0.709). The path of "service quality" to "user satisfaction" showed marginal significance (P=.08) under the 92% CI. Finally, the explanatory power of the model reached 68.9%. CONCLUSIONS Support from the top management, appointment of a nurse supervisor as the change agent, recruitment of seed members to establish a pioneer team, and promotion of the system through the influence of opinion leaders in small groups were critical success factors needed for implementing the system in the case hospital. The target system was proven to be able to improve work performance, and the time saved could be further used for patient care, thereby increasing the value of nursing work. The positive experiences gained from this study could lay the foundation for the further promotion of the new system, and this is for future studies to replicate. The example of the successful experience of the case hospital could also serve as a reference for other hospitals in developing countries like Taiwan with regard to the promotion of nursing informatization. ©Min-Chi Liao, I-Chun Lin.

Although most individuals with OUD in the United States are not in drug abuse treatment, buprenorphine is considered a safe and effective OUD treatment, which reduces illicit opioid use, mortality, and other drug-related harms. However, as buprenorphine prescriptions increase, so does evidence of misused, abused, or diverted buprenorphine. Users' motivations for extratreatment use of buprenorphine (ie, misuse or abuse of one's own prescription or use of diverted medication) may be different from the motivations involved in analgesic opioid products. Previous research is based on small sample sizes and use surveys, and none directly compare the motivations for using buprenorphine products (ie, tablet or film) with other opioid products having known abuse potential. OBJECTIVE The aim of the study was to describe and compare the motivation-to-use buprenorphine products, including buprenorphine/naloxone (BNX) sublingual film and oxycodone eted buprenorphine products for self-treatment, recreational use was a motivation expressed in more than one-third of buprenorphine posts. ©Stephen F F Butler, Natasha K Oyedele, Taryn Dailey Govoni, Jody L Green.

However, very few of them know how to select proper information from reliable sources. This can become a problem when health issues are concerned where it is vital to identify incorrect or misleading information. The competence to critically evaluate digital information on health issues is of increasing importance for adolescents. OBJECTIVE The aim of the present study was to assess how children and adolescents rate their online health literacy, how their actual literacy differs from their rating, including the question how their search performance is related to their self-efficacy. To evaluate these questions a criteria-based analysis of the quality of the websites they visited is necessary. Finally, the possibility to increase their online health literacy in a 3-day workshop should be explored. METHODS A workshop with a focus on health literacy was attended barch as well as to slightly improve their respective competence in a workshop. A targeted improvement of health literacy is urgently needed and students need special instruction for that purpose. Further investigations in this area with larger sets of data, feasible with the help of a computer program, are urgently needed. CLINICALTRIALBACKGROUND Quantification of dietary intake is key to the prevention and management of numerous metabolic disorders. Conventional approaches are challenging, laborious, and lack accuracy. The recent advent of depth-sensing smartphones in conjunction with computer vision could facilitate reliable quantification of food intake. OBJECTIVE The objective of this study was to evaluate the accuracy of a novel smartphone app combining depth-sensing hardware with computer vision to quantify meal macronutrient content using volumetry. METHODS The app ran on a smartphone with a built-in depth sensor applying structured light (iPhone X). The app estimated weight, macronutrient (carbohydrate, protein, fat), and energy content of 48 randomly chosen meals (breakfasts, cooked meals, snacks) encompassing 128 food items. The reference weight was generated by weighing individual food items using a precision scale. The study endpoints were (1) error of estimated meal weight, (2) error of estimated meal macronutrient content and a broad range of food items. In addition, the system demonstrated high segmentation performance and low processing time, highlighting its usability. ©David Herzig, Christos T Nakas, Janine Stalder, Christophe Kosinski, Céline Laesser, Joachim Dehais, Raphael Jaeggi, Alexander Benedikt Leichtle, Fried-Michael Dahlweid, Christoph Stettler, Lia Bally.

OBJECTIVE The aim of this study is to assess the use of SMS to capture clinical outcomes that occur at home and identify potential biases in reporting compared to in-person ascertainment. METHODS In the PrEP Implementation in Young Women and Adolescents program, which integrated pre-exposure prophylaxis (PrEP) into antenatal care, postnatal care, and family planning facilities in Kisumu County, Kenya, HIV-negative women 14 years of age or older were offered oral HIV self-tests (HIVSTs) to take home to male partners. Women that brought a phone with a Safaricom SIM to the clinic were offered registration in an automated SMS system (mSurvey) to collect information on HIVST outcomes. link2 Women were asked if they offered the test to their male partners, and asked about the test process and results. HIVST outcomes were collected via SMS (sent 2.5 weeks later), in-person (if women returned for a f increase reporting of sensitive information.  . ©Alison L Drake, Emily Begnel, Jillian Pintye, John Kinuthia, Anjuli D Wagner, Claire W Rothschild, Felix Otieno, Valarie Kemunto, Jared M Baeten, Grace John-Stewart.

There is a lack of digital interventions which are tailored to the needs of people living with all types of cancer. We developed a six week, digital, peer delivered, self-management programme iHOPE. The programme is underpinned by positive psychology and cognitive behavioural therapy to meet these psychosocial challenges. OBJECTIVE To assess the feasibility of the iHOPE programme among people living with cancer. Programme adherence, and satisfaction along with changes in psychological distress and positive wellbeing were measured. METHODS A pre-post, acceptability and feasibility design was used. People living with cancer (n=114) were recruited via a national cancer charity in the United Kingdom and were given access to the iHOPE programme. Demographic and other participant characteristics were recorded. Participants completed digital measures at baseline and the endr of recurrence (all P less then .001) and increased for positive mental wellbeing, hope (both P less then .001) and gratitude (P=0.015). CONCLUSIONS The feasibility evidence is promising, showing that the peer-delivered, digital iHOPE programme is acceptable and practical. Implementation of the iHOPE programme on a wider scale will incorporate further research and development to maximise completion rates of the measures. Initial effectiveness data suggest positive impacts on important cancer-related quality of life and mental wellbeing outcomes. A randomised controlled trial design with longer follow up is needed to confirm the potential of the iHOPE programme for improving mental and physical health outcomes for cancer survivors. CLINICALTRIALBACKGROUND The trend of quick evolvement and increased digital data in today's operating rooms leads to construction of hybrid operating rooms (hybrid ORs). There is often a main control room with monitors for integrating intra-operative data from multiple devices in the hybrid OR. But there is no adequate solution for communicating the data with people outside the OR. OBJECTIVE The objective of the research was to design an intelligent operating room system (iOR system) augmented onto the existing information-technology infrastructure of hybrid OR in order to stream surgery performance and intra-operative imaging data. link3 METHODS In this study, the authors used the all-in-one device with synergetic encoder and decoder. The device was able to stream multiple sources to one single display. The lossless video and images from specific surgical workflows were streamed outside the hybrid OR through network protocols, and were further managed by a streaming server and wireless control system. The steps of the research included a) defining requirements and feasibility of iOR system in the hybrid OR, b) connecting multiple sources, c) setting-up equipments across the hybrid OR and the conference room, d) designing video management system, e) real-time streaming under specific surgical workflows. RESULTS The wired streaming video were shown simultaneously on the display in the hybrid OR and on the display in the conference room with near-zero latency. And the interactive video between the hybrid OR and the outside conference room could be achieved through the bi-directional wireless control system. Furthermore, the functions of recording, archiving, and playback were successfully provided by the streaming server. The easily available hardware components and open access of programming reduced the cost to construct such kind of streaming system. CONCLUSIONS This flexible and cost-effective iOR system not only provided educational benefits but also contributed for surgical tele-mentoring.
