Effect of a phone reminder system on patient-centered tuberculosis treatment adherence among adults in Northwest Ethiopia: a randomised controlled trial.

OBJECTIVES: This study aimed to evaluate the effect of the phone reminder system on patient-centred TB treatment adherence during continuation phase, where patients are responsible for taking medication at home. METHODS: We conducted a two-arm randomised controlled trial on adult patients with TB during the continuation phase. In the intervention arm, patients received routine care plus phone-based weekly pill refilling and daily medication reminders. In the control arm, participants received only routine care. A covariate adaptive randomisation technique was used to balance covariates during allocation. The primary outcome was adherence to patient-centred TB treatment, and secondary outcomes included provider-patient relationship and treatment outcomes. We applied per-protocol and intention-to-treat analysis techniques. RESULTS: We randomised 306 patients to intervention (n=152) and control (n=154) groups. Adherence to patient-centred TB treatment was 79% (110/139) in intervention and 66.4% (95/143) in control groups, with relative risk (RR) (95% lower CI) (RR=1.632 (1.162 to ∞); p=0.018, one tailed). Good provider-patient relationship was 73.3% (102/139) in intervention group and 52.4% (75/143) in control group, p=0.0001. TB treatment success was 89.5% (136/152) in intervention group and 85.1% (131/154) in control group, p=0.1238. CONCLUSIONS: Mobile phone-based weekly refilling with daily medication reminder system improved adherence to patient-centred TB treatment and provider-patient relationship; however, there was no significant effect on treatment success.

Incidental Findings in the Trauma Population: Interdisciplinary Approach and Electronic Medical Record Reminder Association with Pre-Discharge Reporting and Medicolegal Risk.

BACKGROUND: Incidental findings (IFs) are reported in 20% or more of trauma CT scans. In addition to the importance of patient disclosure, there is considerable legal pressure to avoid missed diagnoses. We reported previously that 63.5% of IFs were disclosed before discharge and with 20% were nondisclosed. We initiated a multidisciplinary systemic plan to effect predischarge disclosure by synoptic CT reports with American College of Radiology recommended follow-up, electronic medical records discharge prompts, and provider education. STUDY DESIGN: Prospective observational series patients from November 2019 to February 2020 were included. Statistical analysis was performed with SPSS, version 21 (IBM Corp). RESULTS: Eight hundred and seventy-seven patients underwent 1 or more CT scans for the evaluation of trauma (507 were male and 370 were female). Mean age of the patients was 57 years (range 14 to 99 years) and 96% had blunt injury. In 315 patients, there were 523 IFs (1.7 per patient); the most common were lung (17.5%), kidney (13%), and liver (11%). Radiology report compliance rate was 84% (210 of 249 patients). There were 66 studies from outside facilities. Sixteen IFs were suspicious for malignancy. A total of 151 patients needed no follow-up and 148 patients needed future follow-up evaluation. Predischarge IF disclosure compliance rate was 90.1% (286 patients); 25 were post discharge. Four patients remained undisclosed. Compared with our previous report, clearer reporting and electronic medical records prompts increased predischarge disclosure from 63.5% to 90.1% (p < 0.01, chi-square test) and decreased days to notification from 29.5 (range 0 to 277) to 5.2 (range 0 to 59) (p < 0.01, Mann-Whitney U test). CONCLUSIONS: Timely, complete disclosure of IFs improves patient outcomes and reduces medicolegal risk. Collaboration among trauma, radiology, and information technology promotes improved disclosure in trauma populations.

Electronic Health Record Reminders for Chlamydia Screening in an American Indian Population.

OBJECTIVES: Indian Health Service (IHS) screening rates for Chlamydia trachomatis are lower than national rates of chlamydia screening in the Southwest. We describe and evaluate the effect of a public health intervention consisting of electronic health record (EHR) reminders to alert health care providers to screen for chlamydia at an IHS facility. We also conducted an awareness presentation among health care providers on chlamydia screening. METHODS: We conducted our intervention from November 1, 2013, through October 31, 2015, at an IHS facility in the Southwest. We implemented algorithms that queried database values to assess chlamydia screening performance in 6 clinical departments. We presented data on the screening performance of clinical departments and health care providers (de-identified) in the awareness presentations. We re-queried database values 1 and 2 years after implementation of the EHR reminder intervention to evaluate before-and-after screening rates, comparing data among all patients and among female patients only. RESULTS: We found small, sustained relative increases in chlamydia screening rates during the 2012-2015 evaluation period: 20.8% pre-intervention to 24.9% and 24.2% one and two years postintervention, respectively, across all patients; 32.3% preintervention to 36.6% and 35.6% one and two years postintervention, respectively, among female patients. Increases in clinical department-specific screening rates varied and were most prominent in internal medicine (35.8% preintervention to peak 65.8% postintervention). The 1 clinic (obstetrics-gynecology) that did not receive an awareness presentation showed a consistent downward trend in screening rates, although absolute rates were consistently higher in that clinic than in other clinics. CONCLUSIONS: Awareness presentations that offer feedback to health care providers on screening performance, heighten provider awareness of the importance of chlamydia screening, and promote development of novel provider-initiated screening protocols may help to increase screening rates when combined with EHR reminders.

An analytical model to evaluate reminders for medication adherence.

OBJECTIVES: Several interventions have been proposed to improve medication adherence including those using reminders. The performance of reminders, including effectiveness and side effects, varies widely in different settings. We must study this for improving decision making on how, when, and where to use what type of reminders. METHODS: Analytical modeling is an effective and low-cost method to derive preliminary or intermediate results and insights for further study of interventions for medication adherence. We developed an analytical model that can be used to evaluate the performance of reminders in various settings, including effectiveness, side effects, and healthcare cost savings for medication adherence. RESULTS: Context-aware reminders perform better than simple reminders for willing patients even when they completely rely on reminders for taking their doses. Simple reminders lead to more side effects than context-aware reminders. Further, context-aware reminders generate more healthcare savings without side effects and a comparable cost of the intervention. The results contribute to an improved understanding of reminders and are used to derive a set of guidelines for patients, healthcare professionals, decision-makers, and mobile app developers. CONCLUSIONS: The proposed model is a low cost and effective tool to derive results and insights for the use of reminders in different settings to improve medication adherence. Therefore, the model can be utilized as a decision-making tool for deciding whether to pursue an RCT on healthcare interventions. The analytical model can be extended for complex scenarios of multiple interdependent medications, adaptation with patients' condition and behavior, and composite interventions.

Use of Person Locator Service to Facilitate Immunization Information System-Based Adolescent Reminder Project.

OBJECTIVE: To determine the impact of using a person locator service to reduce undeliverable addresses for an immunization information system (IIS)-based reminder project. DESIGN: Return mail was compared at address-difference levels between original IIS addresses and updated addresses. SETTING: Minnesota residents were targeted for an immunization reminder postcard based on address. PARTICIPANTS: Both 11- and 12-year-olds with a Minnesota address in Minnesota's IIS. INTERVENTION: An immunization reminder postcard was mailed to households of participants. MAIN OUTCOME MEASURE(S): Reminder postcard return rates were tracked for address-difference levels between original IIS addresses and updated addresses. Return mail rates were track at the ZIP Code Tabulation Area (ZCTA) level and analyzed for demographic characteristic associations. RESULTS: Postcards had significantly lower odds of return when an address was confirmed (odds ratio [OR] = 0.09; 95% confidence interval [CI], 0.08-0.1; P < .001) or had major updates (OR = 0.47; 95% CI, 0.44-0.49; P < .001) than when no new address information was obtained. Significant, positive associations were found between return rate and both ZCTA-level poverty rate (γ = 0.235, P < .001) and ZCTA-level percentage of nonwhite residents (γ = 0.301, P < .001). CONCLUSIONS: Use of a person locator service is a promising method for reducing the barrier incorrect address information poses to successful reminder/recall notification. Implementation of person locator services could improve the data quality of address information in the IIS and success of outreach attempts by IIS users.

Medication adherence: A method for designing context-aware reminders.

OBJECTIVES: Several interventions have been proposed to improve medication adherence including those using reminders. Context-aware reminders can be effective because they operate when the dose is due, has not been taken, and is still safe to take. Although very promising, we find that there is no method to design context-aware reminders. To address these, we focus on proposing a method to design context-aware reminders. METHODS: We conducted a systematic review of context-aware reminders for medication adherence using PRISMA approach. The analysis of literature leads to several interesting observations including the need for a method to design context-aware reminders. In this study, we present Method to Design Context-Aware Reminders (MDCAR) that can also meet special requirements. We used domain experts reasoning to evaluate the designed Context-Aware Reminders for Medication Adherence (CARS-MA). Further, we used analytical model to evaluate reliability, side effects, and cost of intervention. RESULTS: This is the first paper that addresses "how to" design context-aware reminders. The proposed design method can lead to range of context-aware reminders including CARS-MA. The verification, validation, and evaluation of CARS-MA indicate that the context-aware reminders perform better than simple reminders in improving medication adherence. CONCLUSIONS: The proposed method for context-aware reminders will help healthcare professionals and researchers to implement and select a suitable intervention to improve medication adherence. Further, it can lead to decision support systems for patients, healthcare professionals, researchers and policy makers for medication adherence. The design method can be extended for complex scenarios of multiple medications, persistent-reminders, and composite interventions.

A Short Message Service Intervention to Support Adherence to Home-Based Strengthening Exercise for People With Knee Osteoarthritis: Intervention Design Applying the Behavior Change Wheel.

BACKGROUND: Knee osteoarthritis is a chronic condition with no known cure. Treatment focuses on symptom management, with exercise recommended as a core component by all clinical practice guidelines. However, long-term adherence to exercise is poor among many people with knee osteoarthritis, which limits its capacity to provide sustained symptom relief. To improve exercise outcomes, scalable interventions that facilitate exercise adherence are needed. SMS (short message service) interventions show promise in health behavior change. The Behavior Change Wheel (BCW) is a widely used framework that provides a structured approach to designing behavior change interventions and has been used extensively in health behavior change intervention design. OBJECTIVE: The study aimed to describe the development of, and rationale for, an SMS program to support exercise adherence in people with knee osteoarthritis using the BCW framework. METHODS: The intervention was developed in two phases. Phase 1 involved using the BCW to select the target behavior and associated barriers, facilitators, and behavior change techniques (BCTs). Phase 2 involved design of the program functionality and message library. Messages arranged into a 24-week schedule were provided to an external company to be developed into an automated SMS program. RESULTS: The target behavior was identified as participation in self-directed home-based strengthening exercise 3 times a week for 24 weeks. A total of 13 barriers and 9 facilitators of the behavior and 20 BCTs were selected to use in the intervention. In addition, 198 SMS text messages were developed and organized into a 24-week automated program that functions by prompting users to self-report the number of home exercise sessions completed each week. Users who reported ≥3 exercise sessions/week (adherent) received positive reinforcement messages. Users who reported <3 exercise sessions/week (nonadherent) were asked to select a barrier (from a list of standardized response options) that best explains why they found performing the exercises challenging in the previous week. This automatically triggers an SMS containing a BCT suggestion relevant to overcoming the selected barrier. Users also received BCT messages to facilitate exercise adherence, irrespective of self-reported adherence. CONCLUSIONS: This study demonstrates application of the BCW to guide development of an automated SMS intervention to support exercise adherence in knee osteoarthritis. Future research is needed to assess whether the intervention improves adherence to the prescribed home-based strengthening exercise.

Dutch Neonatal Intensive Care Nurses' Perceptions of Pulse Oximeter Saturation Target Limits for Preterm Infants.

PURPOSE: To conduct a national survey to assess practice, knowledge, barriers, and perceptions regarding oxygen saturation (SpO2) target limits among Dutch neonatal intensive care unit (NICU) nurses. DESIGN AND METHODS: Cross-sectional, web-based survey among 667 nurses from 9 level 3 Dutch NICUs. Part of the questions were based on a clinical scenario (28-weeks preterm infant, treated with CPAP, FiO2 0.4). RESULTS: 328 (53.6%) nurses responded to the survey. Of these, 281 (85.7%) reported to know the local policy of SpO2 target limits, and 261 (79.6%) and 244 (74.4%) rightly identified the lower and upper limit, respectively. Six NICUs recently increased their lower SpO2 limit and for 62.0% of their nurses this led to a significant alarm increase. For the majority of the respondents, the baby from the clinical scenario would spend <10% of the time outside the lower or upper SpO2 limits. Automated oxygen control systems were considered a good idea by 59.2% of the respondents, but 53.9% considered allowing parents to participate in FiO2 titration a bad or very bad idea. CONCLUSIONS: The majority of the respondents identified their unit's policy-specified SpO2 target limits and reported that the increase in SpO2 target limits may have led to more alarms. Titration of FiO2 is a part of care that respondents were reluctant to share with parents. PRACTICE IMPLICATIONS: A potential increase in the number of SpO2 alarms may lead to alarm fatigue. Although family-centered care philosophy is widely accepted across Dutch NICUs, there are still barriers to overcome.

Evaluation of a High-risk Patient Reminder System for Colonoscopy Surveillance.

Objectives: In this paper we report the evaluation of a proprietary recall system for promoting compliance with recommended follow-up in high-risk patients. Methods: We conducted a retrospective chart review for patients of an active private colon and rectal surgery practice having colonoscopy in 2006. Patients selected were <80 years of age and assessed to be high-risk by findings at exam or personal/family history of colorectal neoplasm with a recommendation for follow-up surveillance colonoscopy ranging from months to 5 years. Up to 6 months from recommendation was considered to be within compliance. Results: A total of 795 patients met the inclusion criteria, with average age of 63.2 years, 422 (53.1%) being men. Compliance with surveillance colonoscopy recommendations was 62.5%. The recall system impacted patient behavior with compliant patients being sent a median of one letter (average, 1.5) and late or no follow-up patients being sent a median of 4 letters (average, 3.9). Conclusions: Multiple contacts with patients are required to improve compliance with surveillance. Our findings support at least 4 to 5 efforts to remind patients of the importance to schedule a colonoscopy is necessary to optimize compliance.

A Mobile Health Intervention for Prostate Biopsy Patients Reduces Appointment Cancellations: Cohort Study.

BACKGROUND: Inadequate patient education and preparation for office-based procedures often leads to delayed care, poor patient satisfaction, and increased costs to the health care system. We developed and deployed a mobile health (mHealth) reminder and education program for patients scheduled for transrectal prostate biopsy. OBJECTIVE: We aimed to evaluate the impact of an mHealth reminder and education program on appointment cancellation rates, communication frequency, and patient satisfaction. METHODS: We developed a text message (SMS, short message service)-based program with seven reminders containing links to Web-based content and surveys sent over an 18-day period (14 days before through 3 days after prostate biopsy). Messages contained educational content, reminders, and readiness questionnaires. Demographic information, appointment cancellations or change data, and patient/provider communication events were collected for 6 months before and after launching the intervention. Patient satisfaction was evaluated in the postintervention cohort. RESULTS: The preintervention (n=473) and postintervention (n=359) cohorts were composed of men of similar median age and racial/ethnic distribution living a similar distance from clinic. The postintervention cohort had significantly fewer canceled or rescheduled appointments (33.8% vs 21.2%, P<.001) and fewer same-day cancellations (3.8% vs 0.5%, P<.001). There was a significant increase in preprocedural telephone calls (0.6 vs 0.8 calls per patient, P=.02) in the postintervention cohort, but not a detectable change in postprocedural calls. The mean satisfaction with the program was 4.5 out of 5 (SD 0.9). CONCLUSIONS: An mHealth periprocedural outreach program significantly lowered appointment cancellation and rescheduling and was associated with high patient satisfaction scores with a slight increase in preprocedural telephone calls. This led to fewer underused procedure appointments and high patient satisfaction.

Effective ways to retain first-time blood donors: a field-trial study.

BACKGROUND: Regular blood donors are the cornerstone of blood safety. Understanding the donors' behavior to donate blood improves blood donor retention programs. The purpose of this study is to evaluate the return rate of first-time blood donors following different interventions to identify effective ways to retain first-time donors. STUDY DESIGN AND METHODS: The study was conducted on 1356 first-time blood donors at four main blood centers in Iran. The donors were randomly assigned based on different interventions (phone calls, educational letter, emotional letter, incentive, motivational meeting, and no intervention) to six groups. The return rate of donors was defined as a second attempt to donate within 6 months after the first donation. Return rate and 95% confidence intervals (CIs) were calculated and compared among different groups. RESULTS: A total of 394 (29%) donors returned within 6 months for a second donation (95% CI, 0.26-0.31). The return rate in the emotional letter group, educational letter, phone reminder, incentives, motivational meeting, and control groups was 36% (95% CI, 0.31-0.42), 33.2% (95% CI, 0.27-0.38), 31.5% (95% CI, 0.25-0.37), 30% (95% CI, 0.22-0.38), 22% (95% CI, 0.17-0.27) and 22.1% (95% CI, 0.17-0.27), respectively. CONCLUSIONS: This study provides evidence supporting the fact that more first-time blood donors can be motivated to donate again by implementing targeted interventions. It demonstrates that emotional letters, educational letters, and phone reminders were effective in improving the return rate of first-time donors.

Utilization of computerized clinical decision support for potentially inappropriate medications.

Background: Electronic medical record (EMR) alerts may inform point of care decisions, including the decision to prescribe potentially inappropriate medications (PIM) identified in the Beers criteria. EMR alerts may not be considered relevant or informative in the clinician context, leading to a phenomenon colloquially known as "alert fatigue." Objective: To assess the frequency of clinical interaction with EMR alerts and associated deprescribing behaviors in ambulatory settings. Methods: This is a retrospective observational study in two ambulatory clinics (the Kaye Edmonton Clinic Senior's Clinic and the Lynnwood Family Practice Clinic) in Edmonton over an observational period of 30 months. Statistical analysis was done using descriptive statistics, chi-square and regression analysis. Results: The reminder performance for interactions with the alert was 17.2% across the two clinics. The Number Needed to Remind (NNR) or mean number of alerts shown on clinician screens prior to a single interaction of any kind with the alert was 5.8. When actions were defined as a deprescribing (ie discontinuation) event that was related to the alert and that particular interaction in the EMR, the reminder performance was 1.2%, for an NNR of 82.8. Conclusion: The configuration of alerts in the EMR was not associated with a clinically detectable increase in the uptake of the Beers criteria for high hazard medications.

To Text or Not to Text: Electronic Message Intervention to Improve Treatment Adherence Versus Matched Historical Controls.

BACKGROUND: Ensuring treatment adherence is important for the internal validity of clinical trials. In intervention studies where touch points decrease over time, there is even more of an adherence challenge. Trials with multiple cohorts offer an opportunity to innovate on ways to increase treatment adherence without compromising the integrity of the study design, and previous cohorts can serve as historical controls. Electronically delivered nudges offer low-cost opportunities to increase treatment adherence. OBJECTIVE: This study aimed to evaluate the effectiveness of electronic messages (e-messages) on treatment adherence to the last cohort of a parent weight loss intervention during the second half of a year-long trial, when intervention checkpoint frequency decreases. Treatment adherence is measured by intervention class attendance and adherence to the intervention diet. METHODS: All participants in the last cohort (cohort 5, n=128) of a large randomized weight loss study were offered an e-message intervention to improve participant adherence during the last 6 months of a 1-year weight loss program. Overall, 3 to 4 electronic weekly messages asked participants about intervention diet adherence. A propensity score model was estimated using 97 participants who opted to receive e-messages and 31 who declined in cohort 5 and used to pair match cohort 5 e-message participants to a historical control group from cohorts 1 to 4. Moreover, 88 participants had complete data, yielding 176 participants in the final analyses. After matching, intervention and matched control groups were compared on (1) proportion of class attendance between the 6 and 12 month study endpoints, (2) diet adherence, as measured by total carbohydrate grams for low-carbohydrate (LC) and total fat grams for low-fat (LF) diets at 12 months, and (3) weight change from 6 to 12 months. The dose-response relationship between the proportion of text messages responded to and the 3 outcomes was also investigated. RESULTS: Compared with matched controls, receiving e-messages had no effect on (1) treatment adherence; class attendance after 6 months +4.6% (95% CI -4.43 to 13.68, P=.31), (2) adherence; LC -2.5 g carbohydrate, 95% CI -29.9 to 24.8, P=.85; LF +6.2 g fat, 95% CI -4.1 to 17.0, P=.26); or on (3) the secondary outcome of weight change in the last 6 months; +0.3 kg (95% CI -1.0 to 1.5, P=.68). There was a positive significant response correlation between the percentage of messages to which participants responded and class attendance (r=.45, P<.001). CONCLUSIONS: Although this e-message intervention did not improve treatment adherence, future studies can learn from this pilot and may incorporate more variety in the prompts and more interaction to promote more effective user engagement. Uniquely, this study demonstrated the potential for innovating within a multicohort trial using propensity score-matched historical control subjects.

Randomized controlled comparison of cross-sectional survey approaches to optimize follow-up completeness in clinical studies.

INTRODUCTION: In outcome research, incomplete follow-up is a major, yet potentially correctable source of bias. Cross-sectional surveys may theoretically increase completeness of follow-up, but low response rates are reported typically. We investigated whether a pre-notification letter improved patient availability for follow-up phone interviews and thereby improved cross-sectional survey yield. METHODS: A consecutive series of vascular patients was randomly divided into a trial and a validation population. The trial population was then randomized 1:1 to one of two cross-sectional contact strategies: Strategy 1 consisted of direct contact attempts by up to 12 systematically timed phone calls, whereas Strategy 2 used a personalized pre-notification letter to arrange for scheduled phone call interviews. Response rates, average time and efforts needed per patient and overall survey duration were compared. Subsequently, trial findings were externally validated in the validation population. RESULTS: Of 728 consecutive patients, 370 were allocated to the trial population. Trial patients contacted by strategy 1 (n = 183) had a similar profile when compared to trial patients contacted by strategy 2 (n = 187). Follow-up periods following surgery (54.3 versus 53.6 months) and all-cause mortality rates (21.3% versus 18.7%) were comparable between the trial groups. Cross-sectional information on survival outcomes was almost complete after both contact strategies (99.5% versus 98.9%, P = 1.0). In 144/187 strategy 2 patients (77%) interviews were scheduled successfully necessitating significantly less contact attempts (median of 1.3 versus 2.3 per patient, P<0.0001). However, invested time per patient was similar between the groups (median of 10.1 versus 9.6 minutes), and survey strategy 1 completed earlier (median time to contact 4 versus 11 days, P<0.0001). Therefore, strategy 1 was validated in the validation population (n = 358): a low lost to follow-up rate below 1% (P = 1.0) was reconfirmed necessitating an average of 2.3 contact attempts per patient. CONCLUSIONS: Both contact strategies were equally successful in contacting almost all patients cross-sectionally. If systematically timed, direct phone calls were less complicated to organize and faster completed. Given the low time and effort per patient, outcome studies should invest in systematic follow-up surveys to minimize attrition bias.

Text messaging as an intervention for weight loss in emerging adults.

BACKGROUND AND PURPOSE: Rates of overweight and obesity in emerging adults are rapidly increasing and associated with many chronic illnesses, quality of life concerns, and increased health care spending. Effective weight management interventions are needed for this population. The purpose of this study was to examine effects of a text-messaging weight loss intervention on motivation, stage of change for weight loss, and BMI. METHODS: Overweight and obese emerging adults were enrolled (n = 188) and randomized to control or intervention groups. Weight loss information was delivered via a website to both groups. The intervention group also received daily weight loss-related text messages. Motivation, stage of change, and BMI were assessed online, via self-report at baseline, 4, and 8 weeks. CONCLUSIONS: Ninety-five participants were included in the final data analysis. There was a significant increase in motivation and stage of change and decrease in BMI over the study duration, with no significant differences between groups. IMPLICATIONS FOR PRACTICE: Nurse practitioners are well positioned to provide innovative weight loss interventions in a variety of settings. These results provide important insights for the design of effective weight loss treatment for emerging adults and support the use of web-based and text message-based interventions.

Competing needs: a qualitative study of cervical cancer screening attendance among HPV-positive women in Tanzania.

OBJECTIVES: The aim of this study was to understand causes of attendance and non-attendance to a follow-up cervical cancer screening among human papillomavirus (HPV)-positive women. DESIGN: Semistructured, individual interviews with HPV-positive women and cervical cancer screening nurses. The interview guide and initial data analysis were guided by existing health behaviour theories. However, as the theories limited the potential of the data material, a grounded theory framework guided the final data analysis. SETTING: Interviews were conducted in Dar es Salaam, Tanzania, at Ocean Road Cancer Institute (ORCI) or in the homes of screening clients. PARTICIPANTS: 15 interviews were conducted with women who had tested HPV-positive during a patient-initiated screening and been appointed for a follow-up screening 14 months later. Nine women had not attended the follow-up appointment, four had delayed attendance and two had attended on the scheduled date. Further, individual interviews were conducted with the two nurses working at ORCI's screening clinic. RESULTS: Perceived benefits for attending a patient-initiated screening include treatment of gynaecological symptoms and prevention of disease. The key perceived benefit of a health provider-initiated follow-up screening is prevention, which is challenged by the circumstance that it is seen by women as having merely potential benefit and therefore can be postponed when competing needs are present. Perceived challenges for screening attendance include emotional costs, in the form of fear of the disease, fear of the gynaecological examination as well as direct and indirect economic costs, such as transportation costs, lost income and waiting time. CONCLUSION: Cervical cancer screening is one among many tasks that women living in a low-income setting must attend to. Since health provider-initiated follow-up screening is seen as having only potential benefit, attendance can be postponed when competing needs exist. TRIAL REGISTRATION NUMBER: NCT02509702.

Mobile Phone Apps Targeting Medication Adherence: Quality Assessment and Content Analysis of User Reviews.

BACKGROUND: With the accessibility and widespread use of mobile phones, mobile phone apps targeting medication adherence may be useful tools to help patients take medications as prescribed. OBJECTIVE: Our objectives were to (1) characterize and assess mobile phone medication adherence apps guided by a conceptual framework on the focus of adherence interventions and (2) conduct a content analysis of Web-based reviews to explore users' perspectives and experiences with mobile phone medication adherence apps. METHODS: We searched for mobile phone medication adherence apps using keyword searches in Apple and Android operating systems. We characterized all apps in terms of number of downloads, ratings, languages, cost, and disease target. We categorized apps according to 4 key features of (1) alerting to take medication, (2) tracking medication taking, (3) reminding to refill or indicating amount of medication left, and (4) storing medication information. We then selected representative apps from each operating system for detailed quality assessment and user testing. We also downloaded Web-based reviews for these selected apps and conducted a qualitative content analysis using an inductive approach involving steps of initial open coding, construction of categories, and abstraction into themes. RESULTS: We identified 704 apps (443 from Apple and 261 from Android). The majority of apps across both operating systems had 1 or 2 features-specifically, 37.2% (165/443) and 38.1% (169/443) of Apple apps, respectively, and 41.4% (108/261) and 31.4% (108/261) of Android apps, respectively. Quality assessment and user testing of 20 selected apps revealed apps varied in quality and commonly focused on behavioral strategies to enhance medication adherence through alerts, reminders, and logs. A total of 1323 eligible Web-based reviews from these 20 selected apps were analyzed, and the following themes emerged: (1) features and functions appreciated by users, which included the ability to set up customized medication regimen details and reminders, monitor other health information (eg, vitals, supplements, and manage multiple people or pets), support health care visits (eg, having a list of medications and necessary health information in 1 app); (2) negative user experiences that captured technical difficulties (glitches, confusing app navigation, and poor interoperability), dosage schedule, and reminder setup inflexibility; and (3) desired functions and features related to optimization of information input, improvement of reminders, and upgrading app performance (better synchronization or backup of data and interoperability). CONCLUSIONS: A large number of mobile phone medication adherence apps are currently available. The majority of apps have features representing a behavioral approach to intervention. Findings of the content analysis offer mostly positive feedback as well as insights into current limitations and improvements that could be addressed in current and future medication adherence apps.

Text-message responsiveness to blood glucose monitoring reminders is associated with HbA1c benefit in teenagers with Type 1 diabetes.

AIMS: To evaluate an 18-month text-messaging intervention in teenagers with Type 1 diabetes and to assess factors associated with text responsiveness and glycaemic benefit. METHODS: Teenagers with diabetes (N = 147), aged 13-17 years, received two-way text reminders at self-selected times to check blood glucose levels and reply with blood glucose results. RESULTS: At baseline, the participants (48% boys, 78% white, 63% pump-treated) had a mean ± sd age of 14.9 ± 1.3 years, diabetes duration of 7.1 ± 3.9 years and HbA1c concentration of 69 ± 12 mmol/mol (8.5 ± 1.1%). The mean proportion of days with ≥1 blood glucose response declined over time (0-6 months, 60 ± 26% of days, 7-12 months, 53 ± 31% of days, 13-18 months, 43 ± 33% of days). Over 18 months, 49% responded with ≥1 blood glucose result on ≥50% of days (high responders). Regression analysis controlling for baseline HbA1c revealed no significant change in HbA1c from baseline to 18 months in high responders (P = 0.54) compared with a significant HbA1c increase in low responders (+0.3%, P = 0.01). In participants with baseline HbA1c ≥64 mmol/mol (≥8%), high responders were 2.5 times more likely than low responders to have a clinically significant [≥5.5 mmol/mol (≥0.5%)] HbA1c decrease over 18 months (P < 0.05). In participants with baseline HbA1c <64 mmol/mol(<8%), high responders were 5.7 times more likely than low responders to have an 18-month HbA1c <58 mmol/mol (<7.5%; P < 0.05). CONCLUSIONS: Teenagers with Type 1 diabetes who responded to text reminders on ≥50% of days over 18 months experienced clinically significant glycaemic benefit. There remains a need to tailor interventions to maintain teenager engagement and optimize improvements.

Repeated Automated Mobile Text Messaging Reminders for Follow-Up of Positive Fecal Occult Blood Tests: Randomized Controlled Trial.

BACKGROUND: Fecal occult blood tests (FOBTs) are recommended by the US Preventive Services Task Force as a screening method for colorectal cancer (CRC), but they are only effective if positive results are followed by colonoscopy. Surprisingly, a large proportion of patients with a positive result do not follow this recommendation. OBJECTIVE: The objective of this study was to examine the effectiveness of text messaging (short message service, SMS) in increasing adherence to colonoscopy follow-up after a positive FOBT result. METHODS: This randomized controlled trial was conducted with patients who had positive CRC screening results. Randomization was stratified by residential district and socioeconomic status (SES). Subjects in the control group (n=238) received routine care that included an alert to the physician regarding the positive FOBT result. The intervention group (n=232) received routine care and 3 text messaging SMS reminders to visit their primary care physician. Adherence to colonoscopy was measured 120 days from the positive result. All patient information, including test results and colonoscopy completion, were obtained from their electronic medical records. Physicians of study patients completed an attitude survey regarding FOBT as a screening test for CRC. Intervention and control group variables (dependent and independent) were compared using chi-square test. Logistic regression was used to calculate odds ratios (ORs) and 95% CIs for performing colonoscopy within 120 days for the intervention group compared with the control group while adjusting for potential confounders including age, gender, SES, district, ethnicity, and physicians' attitude. RESULTS: Overall, 163 of the 232 patients in the intervention group and 112 of the 238 patients in the control group underwent colonoscopy within 120 days of the positive FOBT results (70.3% vs 47.1%; OR 2.17, 95% CI 1.49-3.17; P<.001); this association remained significant after adjusting for potential confounders (P=.001). CONCLUSIONS: A text message (SMS) reminder is an effective, simple, and inexpensive method for improving adherence among patients with positive colorectal screening results. This type of intervention could also be evaluated for other types of screening tests.

Optimizing Drug-Drug Interaction Alerts Using a Multidimensional Approach.

OBJECTIVES: Excessive alerts are a common concern associated with clinical decision support systems that monitor drug-drug interactions (DDIs). To reduce the number of low-value interruptive DDI alerts at our hospital, we implemented an iterative, multidimensional quality improvement effort, which included an interdisciplinary advisory group, alert metrics, and measurement of perceived clinical value. METHODS: Alert data analysis indicated that DDIs were the most common interruptive medication alert. An interdisciplinary alert advisory group was formed to provide expert advice and oversight for alert refinement and ongoing review of alert data. Alert data were categorized into drug classes and analyzed to identify DDI alerts for refinement. Refinement strategies included alert suppression and modification of alerts to be contextually aware. RESULTS: On the basis of historical analysis of classified DDI alerts, 26 alert refinements were implemented, representing 47% of all alerts. Alert refinement efforts resulted in the following substantial decreases in the number of interruptive DDI alerts: 40% for all clinicians (22.9-14 per 100 orders) and as high as 82% for attending physicians (6.5-1.2 per 100 orders). Two patient safety events related to alert refinements were reported during the project period. CONCLUSIONS: Our quality improvement effort refined 47% of all DDI alerts that were firing during historical analysis, significantly reduced the number of DDI alerts in a 54-week period, and established a model for sustained alert refinements.
