Sharpening clinical decision support alert and reminder designs with MINDSPACE: A systematic review

BACKGROUND

Clinical decision support (CDS) alerts and reminders aim to influence clinical decisions, yet they are often designed without considering human decision-making behaviour. While this behaviour is comprehensively described by behavioural economics (BE), the sheer volume of BE literature poses a challenge to designers when identifying behavioural effects with utility to alert and reminder designs. This study tackles this challenge by focusing on the MINDSPACE framework for behaviour change, which collates nine behavioural effects that profoundly influence human decision-making behaviour: Messenger, Incentives, Norms, Defaults, Salience, Priming, Affect, Commitment, and Ego.

METHOD

A systematic review searching MEDLINE, Embase, PsycINFO, and CINAHL Plus to explore (i) the usage of MINDSPACE effects in alert and reminder designs and (ii) the efficacy of those alerts and reminders in influencing clinical decisions. The search queries comprised ten Boolean searches, with nine focusing on the MINDSPACE effects and one focusing on the term mindspace.

RESULTS

50 studies were selected from 1791 peer-reviewed journal articles in English from 1970 to 2022. Except for ego, eight of nine MINDSPACE effects were utilised to design alerts and reminders, with defaults and norms utilised the most in alerts and reminders, respectively. Overall, alerts and reminders informed by MINDSPACE effects showed an average 71% success rate in influencing clinical decisions (alerts 73%, reminders 69%). Most studies utilised a single effect in their design, with higher efficacy for alerts (64%) than reminders (41%). Others utilised multiple effects, showing higher efficacy for reminders (28%) than alerts (9%).

CONCLUSION

This review presents sufficient evidence demonstrating the MINDSPACE framework's merits for designing CDS alerts and reminders with human decision-making considerations. The framework can adequately address challenges in identifying behavioural effects pertinent to the effective design of CDS alerts and reminders. The review also identified opportunities for future research into other relevant effects (e.g., framing).

Effectiveness of hospital-based strategies for improving childhood immunization coverage: A systematic review

BACKGROUND

Hospital settings represent an opportunity to offer and/or promote childhood vaccination. The purpose of the systematic review was to assess the effectiveness of different hospital-based strategies for improving childhood vaccination coverage.

METHODS

A systematic search of multiple bibliographic databases, thesis databases, and relevant websites was conducted to identify peer-reviewed articles published up to September 20, 2021. Articles were included if they evaluated the impact of a hospital (inpatient or emergency department)-based intervention on childhood vaccination coverage, were published in English or French, and were conducted in high-income countries. High quality studies were included in a narrative synthesis.

RESULTS

We included 25 high quality studies out of 7,845 unique citations. Studies focused on routine, outbreak, and influenza vaccines, and interventions included opportunistic vaccination (i.e. vaccination during hospital visit) (n = 7), patient education (n = 2), community connection (n = 2), patient reminders (n = 2), and opportunistic vaccination combined with patient education and/or reminders (n = 12). Opportunistic vaccination interventions were generally successful at improving vaccine coverage, though results ranged from no impact to vaccinating 71 % of eligible children with routine vaccines and 9-61 % of eligible children with influenza vaccines. Interventions that aimed to increase vaccination after hospital discharge (community connection, patient education, reminders) were less successful.

CONCLUSIONS

Some interventions that provide vaccination to children accessing hospitals improved vaccine coverage; however, the baseline coverage level of the population, as well as implementation strategies used impact success. There is limited evidence that interventions promoting vaccination after hospital discharge are more successful if they are tailored to the individual.

Effect of an electronic reminder of follow-up screening after pregnancy complicated by gestational diabetes mellitus: a randomized controlled trial

AIM

To determine the effectiveness of despatching an electronic reminder of participation in screening for gestational diabetes. The reminder was sent to the women 1-8 years after delivery.

METHODS

A registry-based, randomized controlled trial in the North Denmark Region among women with gestational diabetes. Randomization was made, which included seven groups stratified by the child's birth year (2012-2018). The intervention group received standard care supplemented by an electronic reminder through a secure nationwide email system (n = 731), while the control group received only standard care (n = 732). The primary outcome was based on blood testing for diabetes (OGTT, HbA1c or fasting P-glucose).

RESULTS

A total of 471 (32.1%) women participated in screening. The primary outcome was experienced by 257 women (35.1%) in the intervention group and 214 women (29.2%) in the control group. The effect of the reminder seemed to increase with recipient's age, non-western origin, urban dwelling, and multiparity. Of those who participated in follow-up screening, 56 (3.8%) were diagnosed with type 2 diabetes.

CONCLUSION

Electronic reminders, based on the principles of informed choice and patient-centred care, to women have been shown to support life-long participation in follow-up screening. Attempts to further stimulation of coverage could however be considered.

Effective external reminders impair the practice effect of time-based prospective memory

The practice effect of time-based prospective memory (TBPM) refers to the phenomenon that TBPM task performance can be significantly improved by repetitive behavioural training. However, reminders are a common strategy for people to perform TBPM tasks in daily life. A large amount of evidence shows that reminders can improve TBPM performance when individuals pay less attention to time information. However, the present study was the first to explore whether external reminders might simultaneously impede the practice effect of TBPM. In this study, 81 undergraduate students were randomly assigned to control group (N = 27, M_age  = 20.00, SD_age  = 1.04), reminder group (N = 26, M_age  = 20.35, SD_age  = 1.70) and non-reminder group (N = 28, M_age  = 20.25, SD_age  = 1.17). In the training stage, the reminder group could receive effective external reminders, while the non-reminder group could not. The results of the training stage revealed that compared with the non-reminder group, the reminder group had fewer time monitoring times and better TBPM performance. In the testing stage, when reminders were removed from the reminder group, we found that compared with the control group without TBPM training, the TBPM performance of the reminder group failed to improve, while that of the non-reminder group improved significantly. Meanwhile, the time estimation ability of the reminder group was not as improved as that of the non-reminder group.

Feasibility and efficacy of text messaging to promote care among trauma patients screened for HIV at an urban emergency department in Tanzania

BACKGROUND

Due to the high prevalence of human immunodeficiency virus (HIV) in Tanzania, provider-initiated HIV testing for patients attending any health care setting is recommended. However, follow-up and linkage to care by those tested remain poor. We determined the feasibility and efficacy of text messaging to promote follow-up among otherwise healthy trauma patients who underwent provider-initiated HIV testing and counseling at an emergency department (ED) in Tanzania.

MATERIAL AND METHODS

This randomized controlled trial (RCT) was conducted at Muhimbili National Hospital (MNH) ED between September 2019 and February 2020. Adult trauma patients consenting to HIV testing and follow-up text messaging were randomized to standard care (pre-test and post-test counseling) or standard care plus a series of three short message service (SMS) text message reminders for follow-up in an HIV clinic, if positive, or for retesting, if negative. Investigators blinded to the study assignment called participants 2 months after the ED visit if HIV-positive or 4 months if HIV-negative. We compared the proportion of people in the intervention and control groups completing recommended follow-up. Secondary outcomes were the proportion of patients agreeing to testing, proportion of patients agreeing to receiving text messages, and the proportion of HIV-positive and HIV-negative patients in each study arm who followed up.

RESULTS

Of the 290 patients approached, 255 (87.9%) opted-in for testing and agreed to receive a text message. The median age of the study population was 29 [IQR 24-40] years. There were 127 patients randomized to the intervention group and 128 to the control group. The automated SMS system verified that 381 text messages in total were successfully sent. We traced 242 (94.9%) participants: 124 (51.2%) in the intervention group and 18 (488%) in the control group. A total of 100 (39.2%) subjects reported completing a follow-up visit, of which 77 (60.6%) were from the intervention group and 23 (17.9%) were from the control group (RR = 3.4, 95% CI 2.3-5.0). This resulted in a number needed to treat (NNT) of 2.3. Of the 246 HIV-negative participants, 37% underwent repeat screening: 59% of those in the intervention group and 16% in the control group (RR = 3.7, P = < 0.0001, NNT 2.3). Among the nine positive patients, all five in the intervention group and only three in the controls had follow-up visits.

CONCLUSION

Automated text message is a feasible and effective way to increase follow-up in HIV-tested individuals in a limited income country.

How do reminder systems in follow-up screening for women with previous gestational diabetes work? - a realist review

BACKGROUND

Women with previous gestational diabetes have an increased risk of developing type 2 diabetes later in life. Recommendations therefore urge these women to participate in follow-up screening, 4-12 weeks postpartum and every 1-3 years thereafter. We sought to theorize how reminder interventions to support early detection of diabetes work, for whom, and in what circumstances.

METHODS

We used a method informed by realist review and synthesis. A systematic, iterative search in six electronic databases (PubMed, MEDLINE Ovid, The Cochrane Library, CINAHL, EMBASE) had a primary focus on experimental intervention studies and included additional information in relation to identified intervention studies. Analysis inductively identified context-mechanism-outcome configurations present in the evidence.

RESULTS

We located 16 articles eligible for inclusion. A cross-case comparison identified seven grouped context-mechanism-outcome configurations leading to intervention mechanisms relating to changes in women's reasoning and behavior. Configurations were thematically ordered in relation to Systems Resources, Women's Circumstances, and Continuity of Care. These were mapped onto a socio-ecological model and discussed according to identified middle-range theories.

CONCLUSION

Our findings adds to the body of evidence, that reminders have the potential to be effective in increasing participation in the recommended follow-up screening. Our study may assist researchers and policy and decision makers to analyze and judge if reminders are feasible and/or likely to succeed in their specific context. Further research into the perspective of socially disadvantaged and overweight women is needed to avoid unintended consequences such as social inequality in service use and stigmatization in future programs.

Protein synthesis inhibitor administration before a reminder caused recovery from amnesia induced by memory reconsolidation impairment with NMDA glutamate receptor antagonist

Memory recovery in amnestic animals is one of the most poorly studied processes. In this paper, we examine the role of protein synthesis and a reminder in the mechanisms of amnesia and memory recovery in grape snails trained to conditioned food aversion. Amnesia was induced by the impairment of memory reconsolidation using NMDA (N-methyl d-aspartate) glutamate receptor antagonists. In an early stage of amnesia (day 3), injections of protein synthesis inhibitors into animals combined with a reminder by a conditioned stimulus (CS) led to the recovery of aversive reactions to its presentation. Two types of changes in reactions to CS were revealed. In most animals, a persistent recovery of memory retrieval was found that lasted for at least 10 days. In other snails, aversive responses to CS persisted for 24 h. Isolated injections of inhibitors, injections of inhibitors and a reminder by the learning environment (without presenting a CS), usage of a differentiating stimulus instead of a CS, or inhibitor injections after the reminder did not affect the development of amnesia. The administration of protein synthesis inhibitors and a reminder in the late period after amnesia induction (10 days) did not affect its development or caused a short-term memory recovery. We suggest that amnesia is an active process that develops over time. The reminder induces the reactivation of the amnesia process dependent on protein synthesis, while the administration of protein synthesis inhibitors leads to the impairment of amnesia reactivation and recovery of the state formed before amnesia induction (i.e., recovery of conditioned food aversion memory).

iWash: A smartwatch handwashing quality assessment and reminder system with real-time feedback in the context of infectious disease

Washing hands properly and frequently is the simplest and most cost-effective interventions to prevent the spread of infectious diseases. People are often ignorant about proper handwashing in different situations and do not know if they wash hands properly. Smartwatches are found to be effective for assessing the quality of handwashing. However, the existing smartwatch based systems are not comprehensive enough in terms of achieving accuracy as well as reminding people to handwash and providing feedback to the user about the quality of handwashing. On-device processing is often required to provide real-time feedback to the user, and so it is important to develop a system that runs efficiently on low-resource devices like smartwatches. However, none of the existing systems for handwashing quality assessment are optimized for on-device processing. We present iWash, a comprehensive system for quality assessment and context-aware reminders for handwashing with real-time feedback using smartwatches. iWash is a hybrid deep neural network based system that is optimized for on-device processing to ensure high accuracy with minimal processing time and battery usage. Additionally, it is a context-aware system that detects when the user is entering home using a Bluetooth beacon and provides reminders to wash hands. iWash also offers touch-free interaction between the user and the smartwatch that minimizes the risk of germ transmission. We collected a real-life dataset and conducted extensive evaluations to demonstrate the performance of iWash. Compared to existing handwashing quality assessment systems, we achieve around 12% higher accuracy for quality assessment, as well as we reduce the processing time and battery usage by around 37% and 10%, respectively.

Mobile phone reminders for enhancing uptake, completeness and timeliness of routine childhood immunization in low and middle income countries: A systematic review and meta-analysis

Immunization remains one of the most effective public health interventions offering protection for children from vaccine preventable diseases. However, many children living in low- and- middle income countries do not get adequate immunization due to several factors. Mobile phone reminder interventions have shown great potential in enhancing a number of immunization outcomes. However, the evidence supporting its use in these countries is vague. This systematic review was conducted to provide evidence for mobile phone reminder in enhancing immunization uptake, completeness and timeliness. This review was conducted in accordance to the PRISMA recommendations. Three online databases; PubMed, Cochrane Library and African Journals Online, were systematically searched for potentially relevant studies. Screening of records (titles/abstracts from and full-texts) was done using Covidence. Meta-analyses were conducted using the Cochrane Collaboration Review Manager (v5.4). The GRADEpro was used to evaluate the certainty of evidence/summary of findings. Eleven RCTs assessing immunization uptake, completeness and/or timeliness by means of SMS, phone calls or a combination of voice message and SMS were included in both quantitative and qualitative synthesis. Overall, the included studies were of moderate quality. Majority of the included studies indicated that mobile phone reminders were beneficial. Meta-analyses indicated that using mobile phone reminder interventions for the review outcomes was of variable effect with high level of heterogeneity. A combination of voice message and SMS has a greater effect followed by phone calls then SMS reminders for immunization completeness. The use of SMS for immunization uptake and timeliness were largely insignificant (p > 0.05). Furthermore, evidence to support the efficacy of mobile phone reminder from the GRADE synthesis was between low and moderate. Mobile phone reminders, particularly a combination of voice message + SMS and perhaps phone calls appears to be more effective in enhancing immunization outcomes. However, more studies are required in view of methodological inadequacies in existing studies.

Postcard reminders for HPV vaccination mainly primed parents for providers' recommendations

•

Postcard reminders increased vaccination rates during preventive care visits.

•

Postcards may prime parents for provider recommendations.

•

Reminders may be most effective if combined with provider-targeted interventions.

Parent-targeted reminders increase human papillomavirus (HPV) vaccination rates. Our postcard reminders increased HPV vaccine initiation (receipt of at least one dose) by 60% among girls, but not substantially among boys. To select a complementary intervention that would maximize the effect of reminders, we assessed the percentage increase in HPV vaccine initiation from reminders increasing preventive care visits or increasing the likelihood of vaccine receipt during preventive care.

We conducted a secondary analysis of the postcard reminders from a quasi-experimental, factorial designed, feasibility trial conducted in 2013–2014 among 2,470 11- to 17-year-old girls enrolled in Florida’s Medicaid or Children’s Health Insurance Programs. We used log-linear models and a 4-way decomposition method to estimate the mediating and interacting effects of preventive visits on the effect of postcards on HPV vaccination.

After receiving a preventive visit, 76% (269/356) of girls remained unvaccinated. Nearly half of the effect of postcards on HPV vaccination was mediated by preventive visits (44%; 95% CI = 9.2% to 78.0%). Postcards increased HPV vaccine initiation mainly by increasing the likelihood of HPV vaccine receipt during preventive visits (pure indirect effect = 32.3%; 95% CI = 1.5% to 63.1%), and also by increasing the occurrence of preventive visits (mediated interaction = 11.3%; 95% CI = 1.5 to 21.1).

Reminders likely increased vaccination rates during well visits by priming parents for HPV vaccine conversations with their child’s health care provider. Thus, reminder effectiveness may be increased if timed closely to preventive care visits and/or combined with interventions that improve provider recommendations.

MenACWY vaccination campaign for adolescents in the Netherlands: Uptake and its determinants

BACKGROUND

Between 2015 and 2018 the incidence of meningococcal disease serogroup W increased tenfold in the Netherlands with the highest case fatality among adolescents and young adults. In 2018-2019 a national mass vaccination campaign, with recall after non-attendance, was implemented targeting 14-18-years old adolescents. This study estimated the MenACWY-vaccine uptake and investigated its determinants.

METHODS

The uptake before the start of the vaccination campaign was estimated from the number of vaccines administered by Municipal Health Services and dispensed by public pharmacies, and within the campaign from the national vaccination register. Possible determinants of uptake after the first invitation and recall were investigated among the first group invited for vaccination (born in May-December 2004) using random forest classification analysis.

RESULTS

The uptake was 86% (of which 1.9% before the campaign) among all eligible adolescents and 88% among the first group invited, including 5% uptake achieved after the recall. The most important predictor of vaccination after the first invitation was parents' country of birth (lower uptake when parents were born abroad, range: 52%-Morocco to 88%-Netherlands). The most important predictors among those recalled were, respectively, distance to vaccination location (lower uptake with larger distance, range: 4-6%), percentage of votes for the conservative Christian (reformed) party in the municipality (lower uptake with higher percentage, range: 4-5%) and parents' country of birth (higher uptake when parents were born abroad, range: 4%-Netherlands to 11%-Syria).

CONCLUSIONS

The MenACWY vaccination campaign for adolescents achieved a high uptake, with little vaccine use before the campaign. Parents' country of birth, votes for the conservative reformed political party and distance to the vaccination location were the most important predictors of vaccination. The recall strategy enhanced the uptake and was valuable to diminish immunization disparities. Future vaccination campaigns should put more effort into reaching adolescents with immigrant parents.

Short Message Service Reminders to Parents for Increasing Adolescent Human Papillomavirus Vaccination Rates in a Secondary School Vaccine Program: A Randomized Control Trial

PURPOSE

In Victoria (Australia), the human papillomavirus (HPV) vaccine is delivered within a state-wide secondary school vaccine program, administered by local government. This study aimed to test the hypothesis that sending a short message service (SMS) reminder to parents who had consented to their child's receiving the HPV vaccine would lead to greater uptake of the vaccine within the program. The secondary aim was to assess the effect of self-regulatory versus motivational message content in the SMS.

METHODS

A randomized control trial design was used across 31 schools within seven local government areas. Parents of 4,386 consented adolescents were randomized into three study conditions: motivational SMS versus self-regulatory SMS versus no SMS. Follow-up extended beyond the final school visit to the end of the calendar year to capture those who may have attended a catch-up vaccination session.

RESULTS

On the day of the final school visit, 85.71% of consented students in the control condition received the HPV vaccine, compared with 88.35% (2.64% point increase) in the motivational message condition, and 89.00% (3.29% point increase) in the self-regulatory message condition, χ² (2, N = 4,386) = 8.31, p = .016. Both intervention messages were similarly effective at increasing vaccination rates. This effect was maintained in the extended follow-up period.

CONCLUSIONS

The trial findings supported the hypothesis that SMS reminders to parents/guardians would lead to greater uptake of the HPV vaccine in adolescents participating in school-based vaccination. Also, this effect was observed whether we used a motivational or self-regulatory message framework.

The effects of reminders for colorectal cancer screening: participation and inequality

PURPOSE

To investigate the effect of sending out reminders for colorectal cancer screening on socioeconomic and demographic inequalities in screening uptake.

METHODS

All citizens aged 50-74 in Denmark are invited every 2 years for colorectal cancer screening. Non-participants receive an electronically distributed reminder. Data for these analyses were derived from national registers. Socioeconomic status was measured by income and educational level. Demographic variables included age, gender and marital status, and the analyses were stratified by immigration status. Logistic regression analyses were conducted to estimate the odds of non-participation for invited citizens and for reminded citizens divided by socioeconomic and demographic predictors.

RESULTS

Of 763,511 native Danes invited for screening from 2014 to 2015, 387,116 (50.70%) participated after the initial invitation and 133,470 after receiving a reminder. Differences in participation were present in relation to all subgroups among both the invited citizens and reminded citizens. Differences persisted after full model adjustments with reductions for demographic variables. Odds ratio (OR) for non-participation in the eldest age group was 0.32 (95% CI, 0.32; 0.33) before and 1.11 (95% CI 1, 0.08; 1.14) after the reminder, compared to those under 55 years. OR for the 4th income quartile was 0.54 (95% CI, 0.53; 0.55) before and 0.44 (95% CI, 0.43; 0.45) after the reminder, compared to 1st quartile.

CONCLUSIONS

Reminders increased the overall participation, and the inequalities in participation in relation to demographic factors were reduced after the distribution of reminders. The age differences were especially reduced. The inequalities in participation related to socioeconomic status were, however, slightly increased after reminder distribution.

Increasing influenza vaccine uptake in children: A randomised controlled trial

BACKGROUND

Influenza vaccine is not included in the Hong Kong Government's universal Childhood Immunisation Programme but eligible children can receive subsidised vaccine through the private sector using the Vaccination Subsidy Scheme (VSS). This study examined whether a simple intervention package can increase influenza vaccine uptake in Hong Kong children.

METHODS

Two study samples were enrolled: families of children who had participated in a previous knowledge, attitudes and practices study; and mother-infant pairs recruited from postnatal wards. Control groups received publicly available leaflets about VSS. Intervention groups additionally received: (1) a concise information sheet about influenza and its vaccine; (2) semi-completed forms to utilise the subsidy; (3) contacts of VSS clinics that did not charge above the subsidy; and (4) text message reminders for vaccination. Enrolled mothers were contacted when children were approximately 1 and 2 years old to determine influenza vaccination status of the families and their plan to vaccinate their children. Mothers' attitudes towards influenza vaccine were assessed at enrolment and at the end of the study.

RESULTS

A total of 833 eligible mother-infant pairs were enrolled from the two samples. The intervention package improved influenza vaccine uptake by 22% at one year and 25% at two years of age. Maternal influenza vaccine uptake in intervention group was higher during this two-year period in those who had never been previously vaccinated. Mothers' self-efficacy regarding the use of influenza vaccine in her child i.e. belief and confidence in her own ability to make a good decision, was also improved with the intervention.

CONCLUSIONS

A four-component intervention package could improve influenza vaccine uptake in Hong Kong children and their mothers during the first two years of life and depending on vaccine effectiveness could potentially reduce influenza-associated hospital admissions in children below 2 years old by 13-24%.

A population-based reminder intervention to improve human papillomavirus vaccination rates among adolescents at routine vaccination age

OBJECTIVES

Public health authorities have the resources to conduct efficient immunization reminder interventions to improve vaccine uptake. The objective of this initiative was to design and implement a cost-effective centralized HPV vaccine reminder using New York State Immunization Information System data as one of five prespecified activities to increase initiation and completion among 11- to 13-year-old adolescents.

METHODS

The New York State Department of Health sent reminder letters to the parents or guardians of eligible adolescents who were due for the first dose of HPV vaccine and observed HPV vaccine administration in the six months after each mailing. Subjects were randomized into an intervention group, mailed on May 14, 2015 and a control group, mailed on December 8, 2015.

RESULTS

The analysis consisted of 81,558 eligible letter recipients. Letter recipients were 2 percent more likely to initiate vaccination than control subjects. Significant increases in vaccine uptake were observed for all age and gender strata. The intervention cost was $30.95 for each adolescent who initiated the HPV vaccine series. New York State Department of Health received far less public feedback, including negative feedback, about this intervention that was originally anticipated.

CONCLUSIONS

Public health entities can effectively utilize existing resources to conduct large-scale reminder interventions targeting a jurisdiction's entire 11- to 13-year-old population.

Completeness of Human Papilloma Virus Vaccination: A Systematic Review

PROBLEM

It has been reported that some adolescents and young women who started taking human papillomavirus (HPV) vaccination are not completing all three doses. The aim of this study was to systematically review intervention studies on HPV vaccination completion.

ELIGIBILITY CRITERIA

Intervention studies with a comparison group that assessed HPV vaccination completion rate as the primary outcome variable in adolescents and adults younger than 26years of age, and published in English from 2006 to 2016, were eligible for review.

SAMPLE

Five studies from a literature search of CINAHL, EMBASE, PsycARTICLES, PubMed, SCOPUS, and Web of Science databases were included in this review.

RESULTS

The overall quality of the reviewed studies was moderate, and the studies have mainly been conducted in a high-income country. Intervention strategies were DVD-based education on HPV and reminders that were delivered via either electronic or non-electronic methods. Some studies used fixed type of electronic reminders. Others chose preference-based electronic reminders, allowing participants to select one or two delivery options from e-mail, text message, automated telephone message, or Facebook message. Non-electronic reminders were letters sent by standard mail.

CONCLUSIONS

The rates of HPV vaccination completeness increased with the interventions. However, the completeness rate of HPV vaccination remained unsatisfactory and lower than its initiation rate.

IMPLICATIONS

Educational and reminder interventions for HPV vaccination could contribute to HPV vaccination completion. However, this review highlights the need for more high-quality studies to identify the best way to promote vaccination completion.

A systematic review on reminder systems in physical therapy

Background

The main goal of physical therapy is to help the patient gain a better health status. Several studies have investigated the use of reminders to prevent such failures on the patients' side. This article presents a systematic review of the literature concerning reminders in physical therapy.

Methods

Databases were searched until May 2017 and literatures were found from April 1992 until 2017. The literature recruitment strategy was based on applying several keywords and Medical Subject Heading (MeSH) combination running against title and abstract, including concepts such as reminder, physical therapy. The finally selected articles were categorized through reminder aspects such as how, who feedback. Data were extracted according to PRISMA guidelines.

Results

In 47% of studies, the reminder was sent to the patients, 29% to the physical therapists and 12% to the caretaker team. In 24% of the studies, paper-based letters were main medium for reminders while the rest were various types of media like emails and SMS mobile text messages. 35% of the articles showed positive effects of the reminders.

Conclusions

Many reminder methods consisted of SMS, phone calls, letters, emails and notices on the wall were used in physical therapy. Reminders may be used to improve patients' adherence to exercise programs.

Effects of pre-notification, invitation length, questionnaire length and reminder on participation rate: a quasi-randomised controlled trial

Background

Improving participation rates in epidemiologic studies using questionnaires and biological sampling is important for the generalizability of the outcome. The aim of this study was to examine the effects of pre-notification, invitation length, questionnaire length, and reminder on participation rate and to investigate whether some factors contributed to participants doing both the questionnaire and blood sampling as oppose to only one part.

Methods

Our study was embedded within the pilot testing of a large population-based study about prostate cancer screening. Our study sample consisted of 28.134 men between 50 and 69 years of age and living in the region of Stockholm (Sweden) invited to respond to a web-based questionnaire and to provide blood for prostate cancer testing. The men were randomly allocated according to birth of date to receive either: (a) a pre-notification postcard or not; (b) a shorter or a longer invitation letter; (c) a shorter or a longer web-based questionnaire, and (d) a reminder or not. The effects of the survey design factors were tested using chi-square.

Results

The use of a pre-notification (p < 0.0001), a longer questionnaire (p = 0.004) and the use of a reminder (p = 0.02) were associated with an increase in overall participation, i.e. responding to the questionnaire or providing blood for PCT or performing both components.

Conclusions

The results of this pilot study justified the use of a pre-notification and a reminder in the following large population based study since the benefits of increased participation traded off against the greater costs incurred. Furthermore, we were able to use the longer version of the questionnaire, which allowed us to collect more information without risking a lower response rate.

Comparison of ethanol hand sanitizer versus moist towelette packets for mealtime patient hand hygiene

To facilitate patient hand hygiene, there is a need for easy-to-use products. In a survey of 100 patients, a single-use ethanol hand sanitizer packet took less time to access than a single-use moist towelette packet (3 vs 23 seconds) and was preferred by 74% of patients for mealtime hand hygiene. Performance of patient hand hygiene increased when a reminder was provided at the time of meal tray delivery.

A randomised controlled trial to evaluate the impact of sexual health clinic based automated text message reminders on testing of HIV and other sexually transmitted infections in men who have sex with men in China: protocol for the T2T Study

INTRODUCTION

The frequency of screening for HIV and other sexually transmitted infections (STIs) among men who have sex with men (MSM) is still low in China.

METHODS AND ANALYSIS

A sexual health clinic based randomised controlled trial will be conducted in Guangzhou, Wuxi and Shenzhen, China, enrolling 600 MSM. Eligibility will be judged by the pre-programed iPad based questionnaire: (1) age ≥18 years and (2) have had two or more male anal sex partners, or condomless anal sex with a casual male sex partner, or an STI history, in the past 6 months, and (3) provides a valid mobile phone number. Eligible men will be randomly allocated 1:1 to the intervention arm (with monthly text messages reminding them to test for HIV/STIs) or to the control arm (with no reminders). Men in both arms will complete a questionnaire onsite at enrolment and after 12 months, and another questionnaire online at 6 months. Men in both arms will be tested for HIV, syphilis, anal gonorrhoea/chlamydia and penile gonorrhoea/chlamydia at enrolment and at 12 months. The primary outcome is the rate and frequency of HIV testing within the 12 months after enrolment. The secondary outcome is the rate of unprotected anal intercourse. An assessment of the cost effectiveness of this intervention is also planned.

ETHICS AND DISSEMINATION

The study has been approved by the ethical review committees of the University of New South Wales, Australia (HC16803), the Guangdong Provincial Centre for Skin Disease and STI Control (GDDHLS-20160926) and the Wuxi Centre for Disease Control and Prevention (WXCDC2016009), China. Study findings will be submitted to academic journals and disseminated to local health authorities.

Vaccination adherence: Review and proposed model

BACKGROUND

The prevalence of childhood vaccine-preventable diseases can be significantly reduced through adherence to confirmed vaccination schedules. However, many barriers to vaccination compliance exist, including a lack of awareness regarding the importance of vaccines, missing due dates, and fear of complications from vaccinations. The aim of this study is to review the existing tools and publications regarding vaccination adherence, and to propose a design for a vaccination adherence application (app) for smartphones.

METHODS

Android and iOS apps designed for vaccination reminders have been reviewed to examine six elements: educational factor; customizing features; reminder tools; peer education facilitations; feedback, and the language of apps' interface and content. The literature from PubMed has been reviewed for studies addressing reminder systems or tools including apps.

RESULTS

The study has revealed insufficient (n=6) technology-based interventions for increasing childhood vaccination rates by reminding parents in comparison to the fast growth in technology, out of which are two publications discussed mobile apps. Ten apps have been found in apps stores; only one out of them was designed for the Saudi vaccination schedule in Arabic language with some weaknesses. The study proposed a design for a vaccination reminder app that includes a number of features in order to overcome the limitations discussed in the studied reminders, apps, and systems. The design supports the Arabic language and the Saudi vaccination schedule; parental education including peer education; a variety of reminder methods, and the capability to track vaccinations and refer to the app as a personal health record.

CONCLUSION

The study discussed a design for a vaccination reminder app that satisfies the specific requirements for better compliance to children's immunization schedules based on reviewing the existing apps and publications. The proposed design includes element to educate parents and answer their concerns about vaccines. It involves their peers and can encourage the exchange of experiences and overcome vaccine fears. In addition, it could form a convenient child personal health record.

Text message reminders for timely routine MMR vaccination: A randomized controlled trial

OBJECTIVE

Measles-mumps-rubella (MMR) vaccination is important for preventing disease outbreaks, yet pockets of under-vaccination persist. Text message reminders have been employed successfully for other pediatric vaccines, but studies examining their use for MMR vaccination are limited. This study assessed the impact of text message reminders on timely MMR vaccination.

STUDY DESIGN

Parents (n=2054) of 9.5-10.5-month-old children from four urban academically-affiliated pediatric clinics were randomized to scheduling plus appointment text message reminders, appointment text message reminder-only, or usual care. The former included up to three text reminders to schedule the one-year preventive care visit. Both text messaging arms included a text reminder sent 2 days before that visit. Outcomes included appointment scheduling, appointment attendance, and MMR vaccination by age 13 months, the standard of care at study sites.

RESULTS

Children of parents in the scheduling plus appointment text message reminders arm were more likely to have a scheduled one-year visit than those in the other arms (71.9% vs. 67.4%, relative risk ratio (RRR) 1.07 [95% CI 1.005-1.13]), particularly if no appointment was scheduled before randomization (i.e., no baseline appointment) (62.1% vs. 54.7%, RRR 1.14 [95% CI 1.04-1.24]). One-year visit attendance and timely MMR vaccination were similar between arms. However, among children without a baseline appointment, those with parents in the scheduling plus appointment text message reminders arm were more likely to undergo timely MMR vaccination (61.1% vs. 55.1%, RRR 1.11 [95% CI 1.01-1.21]).

CONCLUSION

Text message reminders improved timely MMR vaccination of high-risk children without a baseline one-year visit.

Mobile phone text message reminders: Measuring preferences of people with antipsychotic medication

Mobile technology use, including Short Messaging Service (SMS) text messaging, has increased in health care services. Preferences regarding the type or timing of text messages sent by healthcare providers to people with antipsychotic medication have not yet been fully investigated. This study examines the relationship between patients' demographic characteristics and the tailored messages they select. The study ("Mobile.Net",

ISRCTN

27704027) includes a structured analysis of a random sub-sample of participants who received messages for 12months. The data were collected in 24 sites and 45 psychiatric hospitals in Finland and analyzed with descriptive statistics and Poisson regression models. The study sample involved 562 people on antipsychotic medication, and a total of 2112 text messages (2 to 25 monthly) were analysed. Regarding message content, there was no significant variation in the proportions relating to 'medication', 'treatment appointments' or 'free time'. Monday was the most popular day to receive messages and morning was preferred to later in the day. Age was most closely associated with 'number of messages' and 'time of messages'. Older women and younger men preferred higher numbers of messages (p=0.0031). Participants preferred positive, encouraging and slightly humorous messages. The findings suggest that messages may be acceptable for difficult to access groups in follow-up. This type of intervention may be useful for various types of patients especially for younger males. To further support the evidence about factors related to message utilization and use, it is important to evaluate the effectiveness of text messages in psychiatric care.

Interventions to increase influenza vaccination rates in children with high-risk conditions--a systematic review

BACKGROUND

Influenza is a common cause of morbidity and mortality, especially among the elderly and those with certain chronic diseases. Annual influenza vaccination is recommended for individuals in at-risk groups, but rates of vaccination are particularly low in children with high-risk conditions (HRCs).

OBJECTIVE

To conduct a systematic review of studies that have examined interventions aimed at improving influenza vaccination in children with HRCs.

METHODS

Two databases - PubMed and SCOPUS - were searched (with no time or language restrictions) using a combination of keywords - Influenza AND vaccination OR immunization OR children AND asthma OR malignancy OR high-risk AND reminder. Duplicates were removed, and abstracts of relevant articles were screened using specific inclusion/exclusion criteria. Thirteen articles were selected, and five additional studies were identified following a review of the reference lists of the initial thirteen articles, bringing the total number to eighteen.

RESULTS

Most studies were conducted in the United States. Among the 18 studies, there was one systematic review of a specific intervention in asthmatic children, seven randomized controlled trials (RCTs), six before-and-after studies, one non-randomized controlled trial, one retrospective cohort study, one quasi-experimental post-test study, and one letter to editors. Interventions reported include multi-component strategies, letter reminders, telephone recall, letters plus telephone calls, an asthma education tool and year-round scheduling for influenza vaccination, amongst others.

CONCLUSION

There is good evidence that reminder letters will improve influenza vaccination uptake in children with HRCs, but the evidence that telephone recall or a combination of letter reminder and telephone recall will improve uptake is weak. It is not known if multiple reminder letters are more effective than single letters or if multi-component strategies are more effective than single or dual component strategies. There is a need for further research of these interventions, possibly outside the United States.
