A mixed-methods study of the effectiveness and perceptions of a course design institute for health science educators.

BACKGROUND: Most health care professionals get their start in academics without formal teaching training. As such, institutions encourage participation in opportunities to address gaps in faculty's knowledge of pedagogy and learning theory in order to promote both successful student and patient outcomes. This study aimed to examine the reception of a faculty development program focused on teaching participants the basics of course design. METHODS: Applying a mixed-method approach, this retrospective study used pre/post-tests, assignment grades, self-assessment questionnaires, and focus groups to elucidate the impact of the faculty development intervention on course design. The participants (n = 12) were health educators from a private all-graduate level university with campus locations across the United States, including in the Southwest and Midwest. In the Course Design Institute (CDI), the participating faculty learned evidence-based instructional approaches and techniques to implement contemporary teaching practices. RESULTS: The data from the pre/post-tests and focus groups suggest that participants learned about topics including instructional alignment, learning goals and objectives, instructional strategies, assessment planning, feedback approaches, communicating expectations, and adult learning theories by participating in this course. The final deliverable scores indicate that the CDI graduates were able to apply a backward design process to plan their own instruction. Data from both the survey and the focus groups suggest that participants were satisfied with the experience and particularly appreciated that the course was relevant to them as educators in the health sciences. CONCLUSIONS: The results of this study indicate that the CDI was influential in developing the faculty's knowledge of the course design process, promoted the application of course design and pedagogy skills amongst CDI graduates, and positively impacted self-reported attitudes about their teaching abilities. In addition, feedback from participants indicates that they recognized the value of this program in their own development and they believed it should be a required course for all educators at the institution.

Ethnicity Differences in Sleep Changes Among Prehypertensive Adults Using a Smartphone Meditation App: Dose-Response Trial.

BACKGROUND: African Americans (AAs) experience greater sleep quality problems than non-Hispanic Whites (NHWs). Meditation may aid in addressing this disparity, although the dosage levels needed to achieve such benefits have not been adequately studied. Smartphone apps present a novel modality for delivering, monitoring, and measuring adherence to meditation protocols. OBJECTIVE: This 6-month dose-response feasibility trial investigated the effects of a breathing awareness meditation (BAM) app, Tension Tamer, on the secondary outcomes of self-reported and actigraphy measures of sleep quality and the modulating effects of ethnicity of AAs and NHWs. METHODS: A total of 64 prehypertensive adults (systolic blood pressure <139 mm Hg; 31 AAs and 33 NHWs) were randomized into 3 different Tension Tamer dosage conditions (5,10, or 15 min twice daily). Sleep quality was assessed at baseline and at 1, 3, and 6 months using the Pittsburgh Sleep Quality Index (PSQI) and 1-week bouts of continuous wrist actigraphy monitoring. The study was conducted between August 2014 and October 2016 (IRB #Pro00020894). RESULTS: At baseline, PSQI and actigraphy data indicated that AAs had shorter sleep duration, greater sleep disturbance, poorer efficiency, and worse quality of sleep (range P=.03 to P<.001). Longitudinal generalized linear mixed modeling revealed a dose effect modulated by ethnicity (P=.01). Multimethod assessment showed a consistent pattern of NHWs exhibiting the most favorable responses to the 5-min dose; they reported greater improvements in sleep efficiency and quality as well as the PSQI global value than with the 10-min and 15-min doses (range P=.04 to P<.001). Actigraphy findings revealed a consistent, but not statistically significant, pattern in the 5-min group, showing lower fragmentation, longer sleep duration, and higher efficiency than the other 2 dosage conditions. Among AAs, actigraphy indicated lower sleep fragmentation with the 5-min dose compared with the 10-min and 15-min doses (P=.03 and P<.001, respectively). The 10-min dose showed longer sleep duration than the 5-min and 15-min doses (P=.02 and P<.001, respectively). The 5-min dose also exhibited significantly longer average sleep than the 15-min dose (P=.03). CONCLUSIONS: These findings indicate the need for further study of the potential modulating influence of ethnicity on the impact of BAM on sleep indices and user-centered exploration to ascertain the potential merits of refining the Tension Tamer app with attention to cultural tailoring among AAs and NHWs with pre-existing sleep complaints.

The Discharge Lounge: A Patient Flow Process Solution.

BACKGROUND: Patient flow, from emergency department admission through to discharge, influences hospital overcrowding. We aimed to improve patient flow by increasing discharge lounge (DL) usage. LOCAL PROBLEM: Patients need to receive a continuum of nursing care to encourage compliance with follow-up care after discharge from the acute care setting. METHODS: Baseline data revealed inefficient use of the DL. We targeted the medical-surgical unit with the lowest DL use and trialed interventions over sequential Plan-Do-Study-Act cycles. INTERVENTIONS: After surveying the nursing staff, we assessed the influence of 3 interventions on DL usage: educating staff on patient eligibility, engaging a recruitment scout, and displaying a visual cue notifying staff when a patient's discharge order was written. RESULTS: The unit's average DL use increased from 18% to 36%, while hospital overcrowding and discharge turnaround time decreased. CONCLUSION: The DL is an effective tool to improve patient flow and decrease hospital overcrowding.

What information and resources do carers require pre and post bereavement in the acute hospital setting? A rapid review.

PURPOSE OF REVIEW: This mixed-method, rapid review of published research from 2014 to 2019 aims to explore the experiences of pre and postbereaved carers, and the information that they receive in the acute hospital setting. The quality of articles was evaluated using a standardized quality matrix. The techniques of conceptual analysis and idea mapping were used to create a structured synthesis of the findings. RECENT FINDINGS: From the initial search of 432 articles, ten studies met the inclusion criteria for this review. These studies generated data from 42 patients, 1968 family/carers and 139 healthcare staff. Themes that were generated from a synthesis of the included articles were clear and timely communication, workforce provision and environment. SUMMARY: This review has highlighted the need for improvements in information provision for carers as part of end of life care. Furthermore, the need for specific staff education and training to enable staff to confidently communicate with dying patients and their relatives in the acute setting is also warranted. Understanding and addressing gaps in knowledge and practice are essential to develop strategies in this complex area. Simple strategies can be implemented to improve the care of carers both pre and post bereavement in acute care.

Living Organ Video Educated Donors Program for Kidney Transplant-eligible African Americans to Approach Potential Donors: A Proof of Concept.

BACKGROUND: The purpose of the Living Organ Video Educated Donors (LOVED) program is to address living donor kidney transplantation (LDKT) disparities in African Americans who experience half the rates of LDKTs compared with whites in the United States. METHODS: LOVED is an iterative-designed, distance-based, navigator-led, mobile health educational program, developed via guidance from patients, Self-determination Theory and Social Cognitive Theory. The purpose of this study was to assess the feasibility of LOVED using a proof-of-concept design to increase African Americans' knowledge about the living donor process to improve their willingness to approach others about being a potential kidney donor. The 8-week LOVED program consisted of (1) a computer tablet-delivered education program, (2) group video chat sessions with an African American LDKT recipient navigator, and (3) additional communication between group members and the navigator. RESULTS: Twenty-five participants completed the LOVED study. Poststudy focus groups were analyzed using inductive and deductive qualitative descriptive techniques and analysts found 6 themes reporting LOVED being highly acceptable with the program being overall empowering and helpful. The study had 0% attrition, 90.9% adherence to the education videos and 88% adherence to the video chat sessions. Surveys showed statistically significant improvements in LDKT knowledge, higher willingness to communicate to others about their need, lower donor concerns, and higher self-efficacy about LDKT. CONCLUSIONS: Findings indicate that participation in LOVED can lead to improvements in predictors to increase the number of evaluations and LDKTs in African Americans; however, these findings need to be confirmed in adequately powered, randomized controlled trials. Using LOVED may reduce barriers to broadly address LDKT disparities. Findings from this study will inform the design of a future statewide randomized controlled trials.

Meditation smartphone application effects on prehypertensive adults' blood pressure: Dose-response feasibility trial.

OBJECTIVE: Essential hypertension (EH) is the most common chronic disease in the United States and a major cause of morbidity and mortality. Lifestyle interventions (e.g., diet, exercise, stress management) to reduce blood pressure (BP) are often complex with varying effectiveness. Breathing awareness meditation (BAM) is a stress management strategy with encouraging effects on BP, though widespread dissemination is hampered by the lack of an easy-to-use methodology to train and monitor BAM practices. A smartphone application (Tension Tamer [TT]) that implements BAM and tracks adherence has shown promise in addressing these gaps. This 6-month dose-response feasibility trial evaluated effects of the app on BP to further optimize BAM user guidelines. METHODS: Sixty-four adults with prehypertension were randomized to complete TT-guided BAM sessions for 5-, 10-, or 15-min intervals twice daily over 6 months. Continuous heart rate readings derived from the phone's video camera via reflective photoplethysmography were used as feedback and as an index of time-stamped adherence. Outcomes (resting BP, HR) were collected at baseline, 1-, 3-, and 6-months. RESULTS: Mixed modeling results showed a significant time effect for systolic BP (SBP) with a dose-response effect at Months 3 and 6. Adherence declined over time and was lowest in the 15-min dose condition, though SBP reductions were maintained. Generally, adherence was negatively associated with dose as the study progressed. CONCLUSIONS: Smartphone-implemented BAM appears to reduce SBP and can be a low-cost method to reach large populations. (PsycINFO Database Record

Formative evaluation on cultural tailoring breathing awareness meditation smartphone apps to reduce stress and blood pressure.

BACKGROUND: Chronic stress is an independent risk factor for essential hypertension (EH), cardiovascular disease (CVD), and is sometimes confronted by mal-adaptive coping behaviors (e.g., stress eating, excessive alcohol consumption, etc.). Pre-essential hypertension (preEH) is the leading predictor of future EH status. Breathing awareness meditation (BAM) can result in clinically beneficial blood pressure (BP) reductions, though face-to-face sessions presents barriers to reach those in need. The purpose of this study was to identify if a culturally tailored approach is needed in the design and preferences between groups of preEH African American and White adults toward using a smartphone BAM app, the Tension Tamer (TT) app. METHODS: TT includes audio delivered BAM instructions, real-time heart rate, feedback graphs and motivational reinforcement text messaging. Questionnaires and two focus groups each of African American and White adults, [n=34, mean age =43.1 years, (SD 13.8 years), 44.1% African American] were conducted to understand stress, EH knowledge, app usage along with feedback from a hands-on demonstration of TT. Grounded theory using NVivo 10 was used to develop themes and combined with the questionnaires in the analysis. RESULTS: No racial differences were found in the analysis including app use scenarios, preferences, knowledge, technology use or the attitudes and acceptance toward mobile health (mHealth) programs. Reported stress was high for African Americans [PSS-4: mean 6.87 (SD 3.3) versus mean 4.56 (SD 2.6); P=0.03]. Four main themes were found: (I) stress was pervasive; (II) coping strategies were both positive and negative; (III) BAM training was easy to incorporated; and (IV) tracking stress responses was useful. Responses suggest that additional personalization of app interfaces may drive ownership and adherence to protocols. Measures and reports of heart rate monitoring while in session were favorably viewed with low issues with confidentiality or trust issues on collected session data. CONCLUSIONS: Results suggest that a culturally tailored approach may be unnecessary in the design of BAM apps. Further investigation is warranted for other racial groups, age ranges, and disease conditions.

Design and approach of the Living Organ Video Educated Donors (LOVED) program to promote living kidney donation in African Americans.

PURPOSE: To describe the rationale, methodology, design, and interventional approach of a mobile health education program designed for African Americans with end stage renal disease (ESRD) to increase knowledge and self-efficacy to approach others about their need for a living donor kidney transplant (LDKT). METHODS: The Living Organ Video Educated Donors (LOVED) program is a theory-guided iterative designed, mixed methods study incorporating three phases: 1) a formative evaluation using focus groups to develop program content and approach; 2) a 2-month proof of concept trial (n=27) to primarily investigate acceptability, tolerability and investigate increases of LDKT knowledge and self-efficacy; and 3) a 6-month, 2-arm, 60-person feasibility randomized control trial (RCT) to primarily investigate increases in LDKT knowledge and self-efficacy, and secondarily, to increase the number of living donor inquiries, medical evaluations, and LDKTs. The 8-week LOVED program includes an interactive web-based app delivered on 10″ tablet computer incorporating weekly interactive video education modules, weekly group video chat sessions with an African American navigator who has had LDKT and other group interactions for support and improve strategies to promote their need for a kidney. RESULTS: Phase 1 and 2 have been completed and the program is currently enrolling for the feasibility RCT. Phase 2 experienced 100% retention rates with 91% adherence completing the video modules and 88% minimum adherence to the video chat sessions. CONCLUSIONS: We are in the early stages of an RCT to evaluate the LOVED program; to date, we have found high tolerability reported from Phase 2.

Stroke patients and their attitudes toward mHealth monitoring to support blood pressure control and medication adherence.

BACKGROUND: Mobile health, or mHealth, has increasingly been signaled as an effective means to expedite communication and improve medical regimen adherence, especially for patients with chronic health conditions such as stroke. However, there is a lack of data on attitudes of stroke patients toward mHealth. Such information will aid in identifying key indicators for feasibility and optimal implementation of mHealth to prevent and/or decrease rates of secondary stroke. Our objective was to ascertain stroke patients' attitudes toward using mobile phone enabled blood pressure (BP) monitoring and medication adherence and identify factors that modulate these attitudes. METHODS: Sixty stroke patients received a brief demonstration of mHealth devices to assist with BP control and medication adherence and a survey to evaluate willingness to use this technology. RESULTS: The 60 participants had a mean age of 57 years, were 43.3% male, and 53.3% were White. With respect to telecommunication prevalence, 93.3% owned a cellular device and 25% owned a smartphone. About 70% owned a working computer. Regarding attitudes, 85% felt comfortable with a doctor or nurse using mHealth technologies to monitor personal health information, 78.3% believed mHealth would help remind them to follow doctor's directions, and 83.3% were confident that technology could effectively be used to communicate with health care providers for medical needs. CONCLUSIONS: Mobile device use is high in stroke patients and they are amenable to mHealth for communication and assistance in adhering to their medical regimens. More research is needed to explore usefulness of this technology in larger stroke populations.

Evaluation of an mHealth Medication Regimen Self-Management Program for African American and Hispanic Uncontrolled Hypertensives.

African Americans and Hispanics have disproportionate rates of uncontrolled essential hypertension (EH) compared to Non-Hispanic Whites. Medication non-adherence (MNA) is the leading modifiable behavior to improved blood pressure (BP) control. The Smartphone Medication Adherence Stops Hypertension (SMASH) program was developed using a patient-centered, theory-guided, iterative design process. Electronic medication trays provided reminder signals, and Short Message Service [SMS] messaging reminded subjects to monitor BP with Bluetooth-enabled monitors. Motivational and reinforcement text messages were sent to participants based upon levels of adherence. Thirty-eight African-American (18) and Hispanic (20) uncontrolled hypertensives completed clinic-based anthropometric and resting BP evaluations prior to randomization, and again at months 1, 3 and 6. Generalized linear mixed modeling (GLMM) revealed statistically significant time-by-treatment interactions (p < 0.0001) indicating significant reductions in resting systolic blood pressure (SBP) and diastolic blood pressure (DBP) for the SMASH group vs. the standard care (SC) control group across all time points. 70.6% of SMASH subjects vs. 15.8% of the SC group reached BP control (< 140/90 mmH) at month 1 (p < 0.001). At month 6, 94.4% of the SMASH vs. 41.2% of the SC group exhibited controlled BP (p < 0.003). Our findings provide encouraging evidence that efficacious mHealth, chronic disease, medical regimen, self-management programs can be developed following principles of patient-centered, theory-guided design.

Sustainability of improvements in medication adherence through a mobile health intervention.

Context-Very few patient-centered, theory-guided programs for medication adherence and blood pressure control have been conducted in kidney transplant recipients. Objective-To evaluate preliminary indications of sustainability of improved blood pressure in kidney transplant recipients 12 months after completion of a 3-month randomized controlled trial of a mobile health pilot program to improve blood pressure and medication adherence. Participants and Design-A total of 18 of the 19 trial participants were contacted and all consented to inclusion in the retrospective analysis of their medical records showing their clinic-recorded systolic blood pressures at 3, 6, and 12 months following participation in the 3-month trial of a medical regimen self-management intervention. Results-A significant group difference in systolic blood pressure was observed longitudinally, indicating that the intervention group, as compared with the standard-care group, exhibited lower clinic-measured systolic blood pressures at the 12-month posttrial follow-up visit (P= .01). At 12-month follow-up, success in establishing and sustaining control of systolic blood pressure (<131 mm Hg) was greater in the intervention group (50%) than in the control group (11%). Conclusion-Patients in the intervention group continued to exhibit lower systolic blood pressure than did patients in the control group 12 months after the trial ended, suggesting that the intervention may have a durable impact on blood pressure control that most likely reflects sustained medication adherence. These findings will aid in the development of an adequately powered randomized controlled trial to address the sustainable impact of the intervention program on medication adherence and blood pressure control.

Patient-Centered mHealth Living Donor Transplant Education Program for African Americans: Development and Analysis.

BACKGROUND: There is a critical need to expand the pool of available kidneys for African Americans who are on the transplant wait-list due to the disproportionally lower availability of deceased donor kidneys compared with other races/ethnic groups. Encouraging living donation is one method to fill this need. Incorporating mHealth strategies may be a way to deliver educational and supportive services to African American transplant-eligible patients and improve reach to those living in remote areas or unable to attend traditional group-session-based programs. Before program development, it is essential to perform formative research with target populations to determine acceptability and cultivate a patient-centered and culturally relevant approach to be used for program development. OBJECTIVE: The objectives of this study were to investigate African American kidney transplant recipients' and kidney donors'/potential donors' attitudes and perceptions toward mobile technology and its viability in an mHealth program aimed at educating patients about the process of living kidney donation. METHODS: Using frameworks from the technology acceptance model and self-determination theory, 9 focus groups (n=57) were administered to African Americans at a southeastern medical center, which included deceased/living donor kidney recipients and living donors/potential donors. After a demonstration of a tablet-based video education session and explanation of a group-based videoconferencing session, focus groups examined members' perceptions about how educational messages should be presented on topics pertaining to the process of living kidney donation and the transplantation. Questionnaires were administered on technology use and perceptions of the potential program communication platform. Transcripts were coded and themes were examined using NVivo 10 software. RESULTS: Qualitative findings found 5 major themes common among all participants. These included the following: (1) strong support for mobile technology use; (2) different media formats were preferred; (3) willingness to engage in video chats, but face-to-face interaction sometimes preferred; (4) media needs to be user friendly; (5) high prevalence of technology access. Our results show that recipients were willing to spend more time on education than the donors group, they wanted to build conversation skills to approach others, and preferred getting information from many sources, whereas the donor group wanted to hear from other living donors. The questionnaires revealed 85% or more of the sample scored 4+ on a 5-point Likert scale, which indicates high degree of interest to use the proposed program, belief that other mHealth technologies would help with adherence to medical regimens, and doctors would make regimen adjustments quicker. In addition, high utilization of mobile technology was reported; 71.9% of the participants had a mobile phone and 43.9% had a tablet. CONCLUSIONS: Our study supports the use of an mHealth education platform for African Americans to learn about living donation. However, potential recipients and potential donors have differing needs, and therefore, programs should be tailored to each target audience.

Effects of Hatha yoga on blood pressure, salivary α-amylase, and cortisol function among normotensive and prehypertensive youth.

OBJECTIVE: Evidence is accumulating, predominantly among clinical trials in adults, that yoga improves blood pressure (BP) control, with downregulation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS) projected as underlying mechanisms. This pilot study assessed whether Hatha yoga has the potential to reduce BP among youth and whether dampening of the SNS and/or HPA activity is a likely pathway of change. DESIGN: Thirty-one seventh graders were randomly assigned to a Hatha yoga program (HYP) or attention control (AC) music or art class. Baseline and 3-month evaluations included resting BP; overnight urine samples; and saliva collected at bedtime, upon awakening, and at 30 and 60 minutes after awakening for α-amylase and cortisol assays. RESULTS: Twenty-eight (14 in the HYP group and 14 in the AC group) students were assessed both before and after the intervention. BP changes from pre- to post-intervention were -3.0/-2.0 mmHg for the HYP group and -0.07/-0.79 mmHg for the AC group (p=0.30 and 0.57, respectively). Changes in systolic BP (SBP)/diastolic BP (DBP) for the prehypertensive (75th-94th percentiles for SBP) subgroup analyses were -10.75/-8.25 mmHg for the HYP group (n=4) versus 1.8/1.0 mmHg for the AC group (n=5) (p for SBP=0.02; p for DBP=0.09). Although no statistically significant group differences were observed with changes in SNS or HPA awakening curves (area under curve for α-amylase and cortisol, respectively), a small to moderate effect size was seen favoring a reduction of α-amylase activation for the HYP group (Cohen d=0.34; prehypertensive d=0.20). CONCLUSIONS: A school-based Hatha yoga program demonstrated potential to decrease resting BP, particularly among prehypertensive youth. Reduced SNS drive may be an underlying neurohormonal pathway beneficially affected by the program. A large-scale efficacy/effectiveness randomized clinical trial is warranted.

Mobile Health Medication Adherence and Blood Pressure Control in Renal Transplant Recipients: A Proof-of-Concept Randomized Controlled Trial.

BACKGROUND: Mobile phone based programs for kidney transplant recipients are promising tools for improving long-term graft outcomes and better managing comorbidities (eg, hypertension, diabetes). These tools provide an easy to use self-management framework allowing optimal medication adherence that is guided by the patients' physiological data. This technology is also relatively inexpensive, has an intuitive interface, and provides the capability for real-time personalized feedback to help motivate patient self-efficacy. Automated summary reports of patients' adherence and blood pressure can easily be uploaded to providers' networks helping reduce clinical inertia by reducing regimen alteration time. OBJECTIVE: The aim of this study was to assess the feasibility, acceptability, and preliminary outcomes of a prototype mobile health (mHealth) medication and blood pressure (BP) self-management system for kidney transplant patients with uncontrolled hypertension. METHODS: A smartphone enabled medication adherence and BP self-management system was developed using a patient and provider centered design. The development framework utilized self-determination theory with iterative stages that were guided and refined based on patient/provider feedback. A 3-month proof-of-concept randomized controlled trial was conducted in 20 hypertensive kidney transplant patients identified as non-adherent to their current medication regimen based on a month long screening using an electronic medication tray. Participants randomized to the mHealth intervention had the reminder functions of their electronic medication tray enabled and received a bluetooth capable BP monitor and a smartphone that received and transmitted encrypted physiological data and delivered reminders to measure BP using text messaging. Controls received standard of care and their adherence continued to be monitored with the medication tray reminders turned off. Providers received weekly summary reports of patient medication adherence and BP readings. RESULTS: Participation and retention rates were 41/55 (75%) and 31/34 (91%), respectively. The prototype system appears to be safe, highly acceptable, and useful to patients and providers. Compared to the standard care control group (SC), the mHealth intervention group exhibited significant improvements in medication adherence and significant reductions in clinic-measured systolic blood pressures across the monthly evaluations. Physicians made more anti-hypertensive medication adjustments in the mHealth group versus the standard care group (7 adjustments in 5 patients versus 3 adjustments in 3 patients) during the 3-month trial based on the information provided in the weekly reports. CONCLUSIONS: These data support the acceptability and feasibility of the prototype mHealth system. Further trials with larger sample sizes and additional biomarkers (eg, whole blood medication levels) are needed to examine efficacy and effectiveness of the system for improving medication adherence and blood pressure control after kidney transplantation over longer time periods.

Hispanic migrant farm workers' attitudes toward mobile phone-based telehealth for management of chronic health conditions.

BACKGROUND: Mobile phone-based interventions present a means of providing high quality health care to hard-to-reach underserved populations. Migrant farm workers (MFWs) are among the most underserved populations in the United States due to a high prevalence of chronic diseases yet limited access to health care. However, it is unknown if MFWs have access to mobile phone devices used in mobile health (mHealth) interventions, or if they are willing to use such technologies. OBJECTIVE: Determine rates of ownership of mobile devices and willingness to use mHealth strategies in MFWs. METHODS: A demonstration of mHealth devices and a survey were individually administered to 80 Hispanic MFWs to evaluate use of mobile phones and mHealth devices and willingness to use such technologies. RESULTS: Of the 80 participants, 81% (65/80) owned cell phones capable of sending and receiving health-related messages. Most participants (65/80, 81%) were receptive to using mHealth technology and felt it would be helpful in enhancing medication adherence, self-monitoring health conditions, and receiving quicker medication changes from their doctors (median scores ≥4 on 5-point Likert scales). Relations between age and attitudes toward using mHealth were not statistically significant. CONCLUSIONS: Hispanic MFWs have access to mobile phones and are willing to use mHealth devices. Future work is needed to comprehensively evaluate the degree to which these devices could be used.

Patient attitudes toward mobile phone-based health monitoring: questionnaire study among kidney transplant recipients.

BACKGROUND: Mobile phone based remote monitoring of medication adherence and physiological parameters has the potential of improving long-term graft outcomes in the recipients of kidney transplants. This technology is promising as it is relatively inexpensive, can include intuitive software and may offer the ability to conduct close patient monitoring in a non-intrusive manner. This includes the optimal management of comorbidities such as hypertension and diabetes. There is, however, a lack of data assessing the attitudes of renal transplant recipients toward this technology, especially among ethnic minorities. OBJECTIVE: To assess the attitudes of renal transplant recipients toward mobile phone based remote monitoring and management of their medical regimen; and to identify demographic or clinical characteristics that impact on this attitude. METHODS: After a 10 minute demonstration of a prototype mobile phone based monitoring system, a 10 item questionnaire regarding attitude toward remote monitoring and the technology was administered to the participants, along with the 10 item Perceived Stress Scale and the 7 item Morisky Medication Adherence Scale. RESULTS: Between February and April 2012, a total of 99 renal transplant recipients were identified and agreed to participate in the survey. The results of the survey indicate that while 90% (87/97) of respondents own a mobile phone, only 7% (7/98) had any prior knowledge of mobile phone based remote monitoring. Despite this, the majority of respondents, 79% (78/99), reported a positive attitude toward the use of a prototype system if it came at no cost to themselves. Blacks were more likely than whites to own smartphones (43.1%, 28/65 vs 20.6%, 7/34; P=.03) and held a more positive attitude toward free use of the prototype system than whites (4.25±0.88 vs 3.76±1.07; P=.02). CONCLUSIONS: The data demonstrates that kidney transplant recipients have a positive overall attitude toward mobile phone based health technology (mHealth). Additionally, the data demonstrates that most kidney transplant recipients own and are comfortable using mobile phones and that many of these patients already own and use smart mobile phones. The respondents felt that mHealth offers an opportunity for improved self-efficacy and improved provider driven medical management. Respondents were comfortable with the idea of being monitored using mobile technology and are confident that their privacy can be protected. The small subset of kidney transplant recipients who are less interested in mHealth may be less technologically adept as reflected by their lower mobile phone ownership rates. As a whole, kidney transplant recipients are receptive to the technology and believe in its utility.

Development and validation of a smartphone heart rate acquisition application for health promotion and wellness telehealth applications.

Objective. Current generation smartphones' video camera technologies enable photoplethysmographic (PPG) acquisition and heart rate (HR) measurement. The study objective was to develop an Android application and compare HRs derived from a Motorola Droid to electrocardiograph (ECG) and Nonin 9560BT pulse oximeter readings during various movement-free tasks. Materials and Methods. HRs were collected simultaneously from 14 subjects, ages 20 to 58, healthy or with clinical conditions, using the 3 devices during 5-minute periods while at rest, reading aloud under observation, and playing a video game. Correlation between the 3 devices was determined, and Bland-Altman plots for all possible pairs of devices across all conditions assessed agreement. Results. Across conditions, all device pairs showed high correlations. Bland-Altman plots further revealed the Droid as a valid measure for HR acquisition. Across all conditions, the Droid compared to ECG, 95% of the data points (differences between devices) fell within the limits of agreement. Conclusion. The Android application provides valid HRs at varying levels of movement free mental/perceptual motor exertion. Lack of electrode patches or wireless sensor telemetric straps make it advantageous for use in mobile-cell-phone-delivered health promotion and wellness programs. Further validation is needed to determine its applicability while engaging in physical movement-related activities.

What contributes to perceived stress in later life? A recursive partitioning approach.

One possible explanation for the individual differences in outcomes of stress is the diversity of inputs that produce perceptions of being stressed. The current study examines how combinations of contextual features (e.g., social isolation, neighborhood quality, health problems, age discrimination, financial concerns, and recent life events) of later life contribute to overall feelings of stress. Recursive partitioning techniques (regression trees and random forests) were used to examine unique interrelations between predictors of perceived stress in a sample of 282 community-dwelling adults. Trees provided possible examples of equifinality (i.e., subsets of people with similar levels of perceived stress but different predictors) as well as identification both of contextual combinations that separated participants with very high and very low perceived stress. Random forest analyses aggregated across many trees based on permuted versions of the data and predictors; loneliness, financial strain, neighborhood strain, ageism, and to some extent life events emerged as important predictors. Interviews with a subsample of participants provided both thick description of the complex relationships identified in the trees, as well as additional risks not appearing in the survey results. Together, the analyses highlight what may be missed when stress is used as a simple unidimensional construct and can guide differential intervention efforts.
