- ItemApplying mobile and pervasive computer technology to enhance coordination of work in a surgical ward.(2007-10-03) Hansen, Thomas Riisgaard; Bardram, Jakob ECollaboration coordination and communication are crucial in maintaining an efficient and smooth flow of work in an operating ward This coordination however often comes at a high price in terms of unsuccessfully trying to get hold of people disturbing telephone calls looking for people and unnecessary stress To accommodate this situation and to increase the quality of work in operating wards we have designed a set of pervasive computer systems which supports what we call context mediated communication and awareness These systems use large interactive displays video streaming from key locations tracking systems and mobile devices to support social awareness and different types of communication modalities relevant to the current context In this paper we report qualitative data from a one year deployment of the system in a local hospital Overall this study shows that 75 of the participants strongly agreed that these systems had made their work easier
- ItemAre MSM willing to SMS for HIV prevention?(2013-12-27) Khosropour, Christine M; Lake, Jason G; Sullivan, Patrick SText messaging is a potential HIV prevention tool for men who have sex with men MSM specifically young MSM and MSM of color To determine the willingness of MSM to receive text messages as part of an HIV prevention intervention we administered an online survey to MSM recruited from MySpace com which included questions about mobile phone ownership and willingness to participate in a future text message based HIV research study Of participants 85 n 5 378 reported owning a mobile phone and 49 n 2 483 of mobile phone owners reported being willing to receive text messages in a future HIV research study Black and Hispanic men were more willing than White non Hispanic men to receive text messages Men with a college degree were less willing to receive texts than men with a high school level of education and men 22 years old were less likely to be willing to receive texts than those younger than 22 years of age The authors findings demonstrate that willingness to receive text messages as part of an HIV research study is moderate and mirrors patterns of text message use in age and race Variations in willingness should be taken into account when designing and implementing future interventions
- ItemAssessing adolescent asthma symptoms and adherence using mobile phones.(2013-07-18) Mulvaney, Shelagh A; Ho, Yun-Xian; Cala, Cather M; Chen, Qingxia; Nian, Hui; Patterson, Barron L; Johnson, Kevin BBACKGROUND Self report is the most common method of measuring medication adherence but is influenced by recall error and response bias and it typically does not provide insight into the causes of poor adherence Ecological momentary assessment EMA of health behaviors using mobile phones offers a promising alternative to assessing adherence and collecting related data that can be clinically useful for adherence problem solving OBJECTIVE To determine the feasibility of using EMA via mobile phones to assess adolescent asthma medication adherence and identify contextual characteristics of adherence decision making METHODS We utilized a descriptive and correlational study design to explore a mobile method of symptom and adherence assessment using an interactive voice response system Adolescents aged 12 18 years with a diagnosis of asthma and prescribed inhalers were recruited from an academic medical center A survey including barriers to mobile phone use the Illness Management Survey and the Pediatric Asthma Quality of Life Questionnaire were administered at baseline Quantitative and qualitative assessment of asthma symptoms and adherence were conducted with daily calls to mobile phones for 1 month The Asthma Control Test ACT was administered at 2 study time points baseline and 1 month after baseline RESULTS The sample consisted of 53 adolescents who were primarily African American 34 53 64 and female 31 53 58 with incomes US 40K year or lower 29 53 55 The majority of adolescents 37 53 70 reported that they carried their phones with them everywhere but only 47 25 53 were able to use their mobile phone at school Adolescents responded to an average of 20 1 SD 8 1 of the 30 daily calls received 67 Response frequency declined during the last week of the month b 0 29 PUnder 001 and was related to EMA reported levels of rescue inhaler adherence r 0 33 P 035 Using EMA adolescents reported an average of 0 63 SD 1 2 asthma symptoms per day and used a rescue inhaler an average of 70 of the time SD 35 when they experienced symptoms About half 26 49 53 of the instances of nonadherence took place in the presence of friends The EMA measured adherence to rescue inhaler use correlated appropriately with asthma control as measured by the ACT r 0 33 P 034 CONCLUSIONS Mobile phones provided a feasible method to assess asthma symptoms and adherence in adolescents The EMA method was consistent with the ACT a widely established measure of asthma control and results provided valuable insights regarding the context of adherence decision making that could be used clinically for problem solving or as feedback to adolescents in a mobile or Web based support system
- ItemAudiovisual Presentations on a Handheld PC are Preferred As an Educational Tool by NICU Parents.(2013-04-25) Alur, P; Cirelli, J; Goodstein, M; Bell, T; Liss, JBACKGROUND Health literacy is critical for understanding complex medical problems and necessary for the well being of the patient Printed educational materials PM have limitations in explaining the dynamics of a disease process Multimedia formats may be useful for enhancing the educational process OBJECTIVE To evaluate whether a printed format or animation with commentary on a handheld personal computer PC is preferred as an educational tool by parents of a baby in the NICU METHODS PARENTS EVALUATED TWO FORMATS A 1 page illustrated document from the American Heart Association explaining patent ductus arteriosus PDA and animation with commentary on a handheld PC that explained the physiology of PDA in 1 minute The reading grade level of the PM was 8 6 versus 18 6 for the audio portion of the animated presentation Parents viewed each format and completed a four item questionnaire Parents rated both formats and indicated their preference as printed animation or both RESULTS Forty six parents participated in the survey Parents preferred animation over PM 50 vs 17 4 p 0 02 39 1 expressed that the animation was excellent whereas 4 3 expressed that the PM was excellent pUnder0 001 The order of presentation of formats sex age and educational level of parents did not influence the method preferred p 0 05 CONCLUSION Parents preferred animation on a small screen handheld PC despite a much higher language level Because handheld PCs are portable and inexpensive they can be used effectively at the bedside with low cost animation to enhance understanding of complex disease conditions
- ItemBehavioral support to parents through a cellular-phone website that provides the degree of urgency for medical attention of a child.(2013-08-07) Iwasawa, Mariko; Miyahara, Jyutaro; Noriaki, Terasawa; Nozue, Hiroki; Sumazaki, RyoWhen a child suddenly falls ill the child s family assesses if medical attention is required immediately However even in case of minor illnesses it is not possible to approach a medical institution after consultation hours and the burden on doctors from overtime emergency medical examinations becomes a social problem This study proposes the use of a cellular phone website that provides information about the degree of urgency for medical attention to parents who can choose the child s symptoms on the cellular phone website regardless of the time or place Therefore through this study parents experimentally evaluated the cellular phone website also the effectiveness of this method as a behavioral support for parents was also evaluated When an advice about the degree of urgency for a child s treatment was taken from the cellular phone website the parents felt relieved Thus the distress faced by pediatricians may change completely
- ItemCollecting maternal health information from HIV-positive pregnant women using mobile phone-assisted face-to-face interviews in Southern Africa.(2013-06-10) van Heerden, Alastair; Norris, Shane; Tollman, Stephen; Richter, Linda; Rotheram-Borus, Mary JaneBACKGROUND Most of the world s women living with human immunodeficiency virus HIV reside in sub Saharan Africa Although efforts to reduce mother to child transmission are underway obtaining complete and accurate data from rural clinical sites to track progress presents a major challenge OBJECTIVE To describe the acceptability and feasibility of mobile phones as a tool for clinic based face to face data collection with pregnant women living with HIV in South Africa METHODS As part of a larger clinic based trial 16 interviewers were trained to conduct mobile phone assisted personal interviews MPAPI These interviewers participant group 1 completed the same short questionnaire based on items from the Technology Acceptance Model at 3 different time points Questions were asked before training after training and 3 months after deployment to clinic facilities In addition before the start of the primary intervention trial in which this substudy was undertaken 12 mothers living with HIV MLH took part in a focus group discussion exploring the acceptability of MPAPI participant group 2 Finally a sample of MLH n 512 enrolled in the primary trial were asked to assess their experience of being interviewed by MPAPI participant group 3 RESULTS Acceptability of the method was found to be high among the 16 interviewers in group 1 Perceived usefulness was reported to be slightly higher than perceived ease of use across the 3 time points After 3 months of field use interviewer perceptions of both perceived ease of use and perceived usefulness were found to be higher than before training The feasibility of conducting MPAPI interviews in this setting was found to be high Network coverage was available in all clinics and hardware software cost and secure transmission to the data center presented no significant challenges over the 21 month period For the 12 MHL participants in group 2 anxiety about the multimedia capabilities of the phone was evident Their concern centered on the possibility that their privacy may be invaded by interviewers using the mobile phone camera to photograph them For participants in group 3 having the interviewer sit beside vs across from the interviewee during the MPAPI interview was received positively by 94 7 of MHL Privacy 6 3 and confidentiality 5 3 concerns were low for group 3 MHL CONCLUSIONS Mobile phones were found both to be acceptable and feasible in the collection of maternal and child health data from women living with HIV in South Africa TRIAL REGISTRATION Clinicaltrials gov NCT00972699 http clinicaltrials gov ct2 show NCT00972699 Archived by WebCite at http clinicaltrials gov ct2 show NCT00972699
