A multi-site feasibility study to assess fever and wheezing in children after influenza vaccines using text messaging.

ABSTRACT: BACKGROUND:Using text messaging for vaccine safety monitoring, particularly for non-medically attended events, would be valuable for pandemic influenza and emergency vaccination program preparedness. We assessed the feasibility and acceptability of text messaging to evaluate fever and wheezing post-influenza vaccination in a prospective, observational, multi-site pediatric study. METHODS:Children aged 2-11 years old, with an emphasis on children with asthma, were recruited during the 2014-2015 influenza season from three community-based clinics in New York City, and during the 2014-2015 and 2015-2016 seasons from a private practice in Fall River, Massachusetts. Parents of enrolled children receiving quadrivalent live attenuated (LAIV4) or inactivated influenza vaccine (IIV4) replied to text messages assessing respiratory symptoms (day 3 and 7, then weekly through day 42), and temperature on the night of vaccination and the next seven nights (day 0-7). Missing data were collected via diary (day 0-7 only) and phone. Phone confirmation was obtained for both presence and absence of respiratory symptoms. Reporting rates, fever (T?100.4?°F) frequency, proportion of wheezing and/or chest tightness reports captured via text message versus all sources (text, phone, diary, electronic health record) and parental satisfaction were assessed. RESULTS:Across both seasons, 266 children were analyzed; 49.2% with asthma. Parental text message response rates were high (>70%) across sites. Overall, fever frequency was low (day 0-2: 4.1% [95% confidence interval (CI) 2.3-7.4%]; d3-7: 6.7% [95% CI 4.1-10.8%]). A third (39.2%) of parents reported a respiratory problem in their child, primarily cough. Most (88.2%) of the 52 wheezing and/or chest tightness reports were by text message. Most (88.1%) participants preferred text messaging over paper reporting. CONCLUSIONS:Text messaging can provide information about pediatric post-vaccination fever and wheezing and was viewed positively by parents. It could be a helpful tool for rapid vaccine safety monitoring during a pandemic or other emergency vaccination program. TRIAL REGISTRATION:clinicaltrials.gov Identifier: NCT02295007.

Project description:OBJECTIVES:(1) To develop methods for conducting cluster randomised trials of text messaging interventions utilising routine electronic health records at low cost; (2) to assess the effectiveness of text messaging influenza vaccine reminders in increasing vaccine uptake in patients with chronic conditions. DESIGN:Cluster randomised trial with general practices as clusters. SETTING:English primary care. PARTICIPANTS:156 general practices, who used text messaging software, who had not previously used text message influenza vaccination reminders. Eligible patients were aged 18-64 in 'at-risk' groups. INTERVENTIONS:Practices were randomly allocated to either an intervention or standard care arm in the 2013 influenza season (September to December). Practices in the intervention arm were asked to send a text message influenza vaccination reminder to their at-risk patients under 65. Practices in the standard care arm were asked to continue their influenza campaign as planned. BLINDING:Practices were not blinded. Analysis was performed blinded to practice allocation. MAIN OUTCOME MEASURES:Practice-level influenza vaccine uptake among at-risk patients aged 18-64 years. RESULTS:77 practices were randomised to the intervention group (76 analysed, n at-risk patients=51,121), 79 to the standard care group (79 analysed, n at-risk patients=51,136). The text message increased absolute vaccine uptake by 2.62% (95% CI -0.09% to 5.33%), p=0.058, though this could have been due to chance. Within intervention clusters, a median 21.0% (IQR 10.2% to 47.0%) of eligible patients were sent a text message. The number needed to treat was 7.0 (95% CI -0.29 to 14.3). CONCLUSIONS:Patient follow-up using routine electronic health records is a low cost method of conducting cluster randomised trials. Text messaging reminders are likely to result in modest improvements in influenza vaccine uptake, but levels of patients being texted need to markedly increase if text messaging reminders are to have much effect. TRIAL REGISTRATION NUMBER:ISRCTN48840025.

Project description:INTRODUCTION:The feasibility and accuracy of text messaging to monitor events after influenza vaccination throughout pregnancy and the neonatal period has not been studied, but may be important for seasonal and pandemic influenza vaccines and future maternal vaccines. METHODS:This prospective observational study was conducted during 2013-2014 and analyzed in 2015-2016. Enrolled pregnant women receiving inactivated influenza vaccination at a gestational age <20 weeks were sent text messages intermittently through participant-reported pregnancy end to request fever, health events, and neonatal outcomes. Text message response rates, Day 0-2 fever (?100.4°F), health events, and birth/neonatal outcomes were assessed. RESULTS:Most (80.2%, n=166) eligible women enrolled. Median gestational age was 8.9 (SD=3.9) weeks at vaccination. Response rates remained high (80.0%-95.2%). Only one Day 0-2 fever was reported. Women reported via text both pregnancy- and non-pregnancy-specific health events, not all associated with medical visits. Most pregnancy-specific events in the electronic medical record (EMR) were reported via text message. Of all enrollees, 84.9% completed the study (131 reported live birth, ten reported pregnancy loss). Two losses reported via text were not medically attended; there was one additional EMR-identified loss. Gestational age and weight at birth were similar between text message-reported and EMR-abstracted data and 95% CIs were overlapping for proportions of prematurity, low birth weight, small for gestational age, and major birth defects, as identified by text message-reported versus EMR-abstracted plus text message-reported versus EMR-abstracted data only. CONCLUSIONS:This study demonstrated the feasibility of text messaging for influenza vaccine safety surveillance sustained throughout pregnancy. In these women receiving inactivated influenza vaccination during pregnancy, post-vaccination fever was infrequent and a typical pattern of maternal and neonatal health outcomes was observed.

Project description:BackgroundMobile health technologies can be useful for providing disease self-management information and support to people with inflammatory bowel disease (IBD).ObjectiveThe aim of this study was to test a self-management SMS text messaging intervention for people with IBD. Our goal was to examine intervention feasibility, acceptability, and engagement and to preliminarily evaluate improvements in certain self-reported health outcomes among participants.MethodsWe developed an SMS text messaging program called Text4IBD. The program sent daily support messages and resources about disease self-management over the course of a 2-week, single-group, pretest-posttest intervention to participants (N=114) diagnosed with IBD. We examined intervention feasibility, acceptability, and engagement through Text4IBD message topic recall and use of resources (ie, visiting supplemental websites recommended by the Text4IBD program). We also assessed pretest-posttest measures of IBD-related distress, self-efficacy, perceived support, use of coping strategies, and medication adherence. Analyses examined participants' evaluations of the intervention and compared pretest-posttest changes in secondary outcomes using paired-samples statistics.ResultsApproximately all participants who completed the intervention (n=105) were receptive to Text4IBD and viewed the program as feasible and acceptable. In addition, most participants (103/105, 98.1%) recalled at least one of the message topics sent by the program, and 79% (83/105) of them self-reported engaging with at least one of the external self-management resources recommended by the Text4IBD program. Pretest-posttest results showed reduced IBD-related distress (mean 3.33, SD 0.68 vs mean 2.86, SD 0.73; P<.001) and improvements in most other secondary outcomes.ConclusionsFindings from this study highlight the value of SMS text messaging as a useful digital medium for providing support to people with IBD, particularly to those who may struggle with disease-related distress. Text4IBD was highly feasible and acceptable and may help people self-manage their IBD. Future studies should aim to evaluate this program in a randomized controlled trial in clinical settings.

Project description:BackgroundSMS text messaging programs are increasingly being used for secondary prevention, and have been shown to be effective in a number of health conditions including cardiovascular disease. SMS text messaging programs have the potential to increase the reach of an intervention, at a reduced cost, to larger numbers of people who may not access traditional programs. However, patients regularly reply to the SMS text messages, leading to additional staffing requirements to monitor and moderate the patients' SMS text messaging replies. This additional staff requirement directly impacts the cost-effectiveness and scalability of SMS text messaging interventions.ObjectiveThis study aimed to test the feasibility and accuracy of developing a machine learning (ML) program to triage SMS text messaging replies (ie, identify which SMS text messaging replies require a health professional review).MethodsSMS text messaging replies received from 2 clinical trials were manually coded (1) into "Is staff review required?" (binary response of yes/no); and then (2) into 12 general categories. Five ML models (Naïve Bayes, OneVsRest, Random Forest Decision Trees, Gradient Boosted Trees, and Multilayer Perceptron) and an ensemble model were tested. For each model run, data were randomly allocated into training set (2183/3118, 70.01%) and test set (935/3118, 29.98%). Accuracy for the yes/no classification was calculated using area under the receiver operating characteristics curve (AUC), false positives, and false negatives. Accuracy for classification into 12 categories was compared using multiclass classification evaluators.ResultsA manual review of 3118 SMS text messaging replies showed that 22.00% (686/3118) required staff review. For determining need for staff review, the Multilayer Perceptron model had highest accuracy (AUC 0.86; 4.85% false negatives; and 4.63% false positives); with addition of heuristics (specified keywords) fewer false negatives were identified (3.19%), with small increase in false positives (7.66%) and AUC 0.79. Application of this model would result in 26.7% of SMS text messaging replies requiring review (true + false positives). The ensemble model produced the lowest false negatives (1.43%) at the expense of higher false positives (16.19%). OneVsRest was the most accurate (72.3%) for the 12-category classification.ConclusionsThe ML program has high sensitivity for identifying the SMS text messaging replies requiring staff input; however, future research is required to validate the models against larger data sets. Incorporation of an ML program to review SMS text messaging replies could significantly reduce staff workload, as staff would not have to review all incoming SMS text messages. This could lead to substantial improvements in cost-effectiveness, scalability, and capacity of SMS text messaging-based interventions.

Project description:BACKGROUND: Face-to-face interviews by trained field workers are commonly used in household surveys. However, this data collection method is labor-intensive, time-consuming, expensive, prone to interviewer and recall bias and not easily scalable to increase sample representativeness. OBJECTIVE: To explore the feasibility of using text messaging to collect information on infant and young child feeding practice in rural China. METHODS: Our study was part of a clustered randomized controlled trial that recruited 591 mothers of children aged 12 to 29 months in rural China. We used the test-retest method: first we collected data through face-to-face interviews and then through text messages. We asked the same five questions on standard infant and young child feeding indicators for both methods and asked caregivers how they fed their children yesterday. We assessed the response rate of the text messaging method and compared data agreement of the two methods. FINDING: In the text messaging survey, the response rate for the first question and the completion rate were 56.5% and 48.7%, respectively. Data agreement between the two methods was excellent for whether the baby was breastfed yesterday (question 1) (kappa, ??=?0.81), moderate for the times of drinking infant formula, fresh milk or yoghurt yesterday (question 2) (intraclass correlation coefficient, ICC?=?0.46) and whether iron fortified food or iron supplement was consumed (question 3) (??=?0.44), and poor for 24-hour dietary recall (question 4) (ICC?=?0.13) and times of eating solid and semi-solid food yesterday (question 5) (ICC?=?0.06). There was no significant difference in data agreement between the two surveys at different time intervals. For infant and young child feeding indicators from both surveys, continued breastfeeding at 1 year (P?=?1.000), continued breastfeeding at 2 years (P?=?0.688) and minimum meal frequency (P?=?0.056) were not significantly different, whereas minimum dietary diversity, minimum accepted diet and consumption of iron-rich or iron fortified foods were significantly different (P?<?0.001). CONCLUSIONS: The response rate for our text messaging survey was moderate compared to response rate of other studies using text messaging method and the data agreement between the two methods varied for different survey questions and infant and young child feeding indicators. Future research is needed to increase the response rate and improve data validity of text messaging data collection.

Project description:Although skin cancer is largely preventable, it affects nearly 1 of 5 US adults. There is a need for research on how to optimally design persuasive public health indoor tanning prevention messages.The objective of our study was to examine whether framed messages on indoor tanning behavioral intentions delivered through short message service (SMS) text messaging would produce (1) positive responses to the messages, including message receptivity and emotional response; (2) indoor tanning efficacy beliefs, including response efficacy and self-efficacy; and (3) indoor tanning risk beliefs.We conducted a pilot study of indoor tanning prevention messages delivered via mobile phone text messaging in a sample of 21 young adult women who indoor tan. Participants completed baseline measures, were randomly assigned to receive gain-, loss-, or balanced-framed text messages, and completed postexposure outcome measures on indoor tanning cognitions and behaviors. Participants received daily mobile phone indoor tanning prevention text messages for 1 week and completed the same postexposure measures as at baseline.Over the 1-week period there were trends or significant changes after receipt of the text messages, including increased perceived susceptibility (P<.001), response efficacy beliefs (P<.001), and message receptivity (P=.03). Ordinary least squares stepwise linear regression models showed an effect of text message exposure on self-efficacy to quit indoor tanning (t6=-2.475, P<.02). Ordinary least squares linear regression including all measured scales showed a marginal effect of SMS texts on self-efficacy (t20=1.905, P=.08). Participants endorsed highly favorable views toward the text messaging protocol.This study supports this use of mobile text messaging as an indoor tanning prevention strategy. Given the nature of skin cancer risk perceptions, the addition of multimedia messaging service is another area of potential innovation for disseminating indoor tanning prevention messages.

Project description:Background: There are at present no evidence-based interventions for marijuana use during pregnancy, despite it being by far the most commonly used illicit drug during pregnancy. Lack of treatment-seeking, combined with implementation challenges, has limited the extent to which at-risk women receive interventions of any kind. This study sought to evaluate the feasibility and acceptability of two high-reach technology-based interventions: electronic screening and brief intervention (e-SBI) and tailored text messaging, delivered either alone or in combination. Materials and Methods: In this exploratory feasibility trial, pregnant women seeking prenatal care services and scoring positive for marijuana use risk (n?=?45) were randomly assigned to e-SBI, text messaging, or e-SBI plus text messaging. We examined completion rates and acceptability ratings as a function of intervention condition and participant characteristics. Results: All participants assigned to receive the e-SBI (n?=?30) were able to complete it during the in-clinic baseline session. Participants assigned to text messaging (n?=?30) received a median of 24 text messages before giving birth; 6 of 30 (20%) chose to end text messages before giving birth. Acceptability ratings for the e-SBI were high, with most being above 4.4 on a 5-point scale (e.g., for ease of use, respectfulness, and helpfulness). Acceptability ratings for some aspects of the texting intervention were also high (e.g., for ease of understanding and respectfulness). Participants in the combined e-SBI plus texting condition chose to stop messages at a rate of 13.3% (2 of 15), versus 26.7% (4 of 15) in the texting-only condition (p?=?0.37). Conclusions: These two high-reach intervention elements showed strong feasibility and modest to high acceptability. Future efforts evaluating efficacy are warranted, and should specifically examine the possibility that combining text messaging with a brief intervention may promote retention.
