Personalized Patient Data and Behavioral Nudges to Improve Adherence to Chronic Cardiovascular Medications

Poor medication adherence is common. Text messaging is increasingly used to change patient behavior but often not rigorously tested. To compare different types of text messaging strategies with usual care to improve medication refill adherence among patients nonadherent to cardiovascular medications. Patient-level randomized pragmatic trial between October 2019 to April 2022 at 3 US health care systems, with last follow-up date of April 11, 2023. Adult (18 to <90 years) patients were eligible based on diagnosis of 1 or more cardiovascular condition(s) and prescribed medication to treat the condition. Patients who did not opt out and had a 7-day refill gap were randomized to 1 of 4 study groups. Generic text message refill reminders (generic reminder); behavioral nudge text refill reminders (behavioral nudge); behavioral nudge text refill reminders plus a fixed-message chatbot (behavioral nudge + chatbot); usual care. Primary outcome was refill adherence based on pharmacy data using proportion of days covered at 12 months. Secondary outcomes were clinical events of emergency department visits, hospitalizations, and mortality. Among 9501 enrolled patients, baseline characteristics across the 4 groups were comparable (mean age, 60 years; 47% female [n = 4351]; 16% Black [n = 1517]; 49% Hispanic [n = 4564]). At 12 months, the mean proportion of days covered was 62.0% for generic reminder, 62.3% for behavioral nudge, 63.0% for behavioral nudge + chatbot, and 60.6% for usual care (P = .06). In adjusted analysis, when compared with usual care, mean proportion of days covered was 2.2 percentage points (95% CI, 0.3-4.2; P = .02) higher for generic reminder, 2.0 percentage points (95% CI, 0.1-3.9; P = .04) higher for behavioral nudge, and 2.3 percentage points (95%, 0.4-4.2; P = .02) higher for behavioral nudge + chatbot, none of which were statistically significant after multiple comparisons correction. There were no differences in clinical events between study groups. Text message reminders targeting patients who delay refilling their cardiovascular medications did not improve medication adherence based on pharmacy refill data or reduce clinical events at 12 months. Poor medication adherence may be due to multiple factors. Future interventions may need to be designed to address the multiple factors influencing adherence.

Enhanced Oral Pre-exposure Prophylaxis (PrEP) Implementation for Ugandan Fisherfolk: Pilot Intervention Outcomes

Mobile populations such as fisherfolk show high HIV incidence and prevalence. We pilot-tested implementation strategies to enhance pre-exposure prophylaxis (PrEP) uptake and adherence in the context of healthcare outreach events in two mainland fisherfolk communities on Lake Victoria, Uganda from September 2021 to February 2022. The implementation strategies included PrEP adherence supporters (selected from PrEP users’ social networks), community workshops (to address misconceptions and stigma, and empower PrEP advocacy), and check-in calls (including refill reminders). PrEP medical records data were collected from 6-months pre-intervention to 6-months post-intervention. Qualitative interviews with 20 PrEP users (10 who continued, 10 who discontinued), 9 adherence supporters, and 7 key partners (providers, community leaders) explored acceptability. Percentages of PrEP initiators (of those eligible) were significantly higher during the intervention (96.5%) than 6-months before the intervention (84.5%), p < 0.0001; percentages of PrEP users who persisted (i.e., possessed a refill) 6-months post-initiation (47.9% vs. 6.7%) and had at least 80% PrEP coverage (based on their medication possession ratio) from the initiation date to 6-months later (35.9% vs. 0%) were higher during versus pre-intervention, p < 0.0001. A comparison fisherfolk community with better healthcare access had lower uptake (78.3%; p < 0.0001) and persistence at 6-months (34.0%; p < 0.001), but higher coverage during the intervention period (70.4%; p < 0.0001). Qualitative data suggested the strategies promoted PrEP use through reduced stigma and misconceptions. The intervention bundle cost was $223.95, $172.98, and $94.66 for each additional person for PrEP initiation, persistence, and coverage, respectively. Enhanced community-based PrEP implementation that fosters a supportive community environment can improve PrEP use in mobile populations without easy access to healthcare. (NCT05084716).

Assessing the impact of a financial incentive and refill reminder program on medication adherence and costs.

Improving medication adherence remains an important goal to improve therapeutic outcomes and lower health care costs. Point-of-sale prescription costs and forgetfulness remain top reasons why patients do not adhere to medications. Programs using both text message-based reminders and financial incentives may encourage patients to refill their prescriptions on time by reducing copays through discounts at the point of sale. Sempre Health, the subject of our analysis, provides both text message refill reminders and a dynamic discount incentive program to improve medication adherence. To evaluate the impact of a financial incentive/refill reminder program on medication adherence and total cost of care for patients taking the antithrombotic agents ticagrelor, apixaban, or rivaroxaban in a large regional health plan. After propensity-score matching on demographics, socioeconomic status, baseline copay, prior pharmacy/medical spend, and morbidity, we compared-using a difference-in-differences analytic approach-adherence (measured by proportion of days covered), unplanned health care utilization, and costs (total cost of care, medical, and pharmacy cost) of health plan members who did and did not enroll in the financial incentive/refill reminder program between February 1, 2019, and October 31, 2021, over 1 and 2 years. Because of differences in patient characteristics, we analyzed patients on ticagrelor (the antiplatelet group), apixaban, and rivaroxaban (the anticoagulant group) separately. There were a total of 1,292 one-to-one program and control propensity-matched patients: 166 each for the antiplatelet group and 480 each for the anticoagulant group. The average age of the anticoagulant group was 62 years; more than 60% were male, and approximately 45% had no prior unplanned care events. In contrast, the average age of the antiplatelet group was 57 years; more than 70% were male, and approximately 21% had no prior unplanned care events. In the antiplatelet group, the proportions adherent (proportion of days covered ≥80%) were 63.3% vs 42.8% (P = 0.0002) for program vs controls. Similarly, in the anticoagulant group, the proportion adherent was 77.9% vs 60.2% (P < 0.0001) for program vs controls. Reflecting improved adherence, costs of apixaban and rivaroxaban increased by $79 per member per month (PMPM) (P < 0.0001), with no statistically significant differences in other costs. Similarly, the cost of ticagrelor increased by $77 PMPM (P = 0.0102) with no statistically significant differences in other costs. Finally, there was a 16% (P = 0.032) reduction in emergency department use for those in the program. The financial incentive and refill reminder program was associated with improved adherence to antithrombotic medications, reduced emergency department use, and increased medication costs, but not in total pharmacy, medical, or total cost of care in both subgroups.

Effect of implementation strategies on pre-exposure prophylaxis persistence among female sex workers in South Africa: an interrupted time series study

A disproportionate number of new HIV infections in South Africa are among female sex workers; pre-exposure prophylaxis (PrEP) for HIV prevention is freely available to female sex workers in the country, but unique barriers challenge PrEP persistence. TB HIV Care, a large South African non-profit organisation that provides daily oral PrEP (tenofovir disoproxil fumarate and emtricitabine), has implemented multiple strategies to improve PrEP persistence. We aimed to evaluate the effect of different implementation strategies on PrEP persistence in a large-scale real-world setting. In this interrupted time series study, we estimated level changes in 1-month oral PrEP persistence associated with roll-out of various implementation strategies among female sex workers across nine districts in South Africa. We used routinely collected data from TB HIV Care programme files from June 7, 2016, to April 30, 2021. Poisson regression of 1-month persistence was used to assess the effect of these strategies. In secondary analyses, we tested the association between each of the strategies and 4-month persistence. The median 1-month PrEP persistence for female sex workers was 33% (IQR 27-40). SMS support and refill reminders were associated with an 11% relative increase in 1-month persistence (risk ratio [RR] 1·11, 95% CI 1·02-1·26) and clinical mentoring for PrEP providers was associated with a 127% relative increase (RR 2·27, 95% CI 1·94-2·66) among female sex workers. The loyalty rewards programme was negatively associated with 1-month persistence (RR 0·71, 95% CI 0·67-0·83). Although clinical mentoring improved 4-month persistence, SMS support text messages had no significant effect. Identification and subsequent use of clinical mentoring for PrEP providers and SMS support and refill reminders might improve the usefulness of PrEP overall to prevent new HIV infections among female sex workers. PrEP persistence remains an important issue, and strategies to build on our findings are needed. National Institute of Mental Health and National Institute of Allergy and Infectious Diseases.

Description of patient questions received by clinical pharmacists in the Nudge Study.

The Nudge Study is a patient level-randomized trial testing different text message medication refill reminders sent to patients assigned to 4 arms: (1) usual care, (2) generic text, (3) optimized text, and (4) optimized text plus chatbot. This report describes the frequency and types of patient questions sent to clinical pharmacists (CPs) following text reminders. Patients were enrolled from Denver Health and Hospital Authority (DHHA) and Veterans Affairs Eastern Colorado Health Care System (VA ECHCS) from October 1, 2019, through May 30, 2021. Included patients responded to at least 1 text or interactive voice response (IVR) message. Patients were dichotomized as those who posed at least 1 question to a CP and those who posed no questions. Of the 6,325 patients enrolled in an intervention arm, 3,323 (52.5%) responded to at least 1 text or IVR message, and among those responding, 305 (9.2%) responded with a pharmacist question. Patient factors associated with submitting a CP question included age (45-74 years), enrollment from DHHA, and receipt of the optimized text or optimized text plus chatbot message versus the generic text. Questions to CP were in the following categories: medication related (48.2%), refill logistics (38.4%), cost (9.2%), and other (17.7%). In a text messaging intervention focused on medication refills, there were few questions directed to the CP. Patients assigned to receive optimized texts were more likely to have questions. We hypothesize that this may suggest greater patient engagement regarding their condition, resulting in more questions.

Intervensi pada Pasien Tuberkulosis untuk Meningkatkan Kepatuhan dan Manajemen Diri

This study aims to design and analyze interventions that can be used in tuberculosis patients to improve adherence and self-management in preventing multi-drug-resistant tuberculosis (MDR-TB) events. The research method is a literature review conducted to analyze the concept of intervention in tuberculosis patients. A comprehensive literature search was carried out through an electronic database of CINAHL and PUBMED from publications from early 2020 to December 30, 2022. The results showed that interventions that could be carried out were increasing knowledge, increasing the role of medical staff in motivating and observing both through messages, text, or telephone, improving education through health promotion so that TB patients can comply with treatment, and improving self-management. Other interventions that can improve adherence to TB treatment are psychological counseling, individual education, digital-based medication monitoring (DOTS) WOT, telephone-based pill refill reminders, and medication monitoring), and peer support. In conclusion, good self-management behavior is proven to reduce the progression of diseases, including tuberculosis. Age, attitude, marital status, and home conditions influence self-management. While the knowledge factor indirectly affects self-management through mentality. Thus, knowledge and attitudes require the intervention of other parties who can mediate. This is to avoid the occurrence of Multidrug-Resistant Tuberculosis (MDR-TB).&#x0D; &#x0D; Keywords: Intervention, Compliance, Self Management, Tuberculosis

Effect on medication adherence of applying a specialty pharmacy care model to nonspecialty medications: A quasi-experimental cohort study.

Medication nonadherence is a multifactorial healthcare problem that contributes to increased healthcare costs and morbidity. To improve medication adherence, specialty pharmacies offer services not typically provided by retail pharmacies such as benefits investigation, financial assistance, medication synchronization, and proactive refill reminders. This study assessed the impact of the specialty pharmacy care model on medication adherence for patients on nonspecialty medications. This study was a quasi-experimental cohort comparison of patients who were transferred from a health-system retail pharmacy to a health-system specialty pharmacy between April 1, 2020, and June 30, 2021. The primary endpoint in this study was the difference in mean medication adherence proportion of days covered (PDC) between the post-transfer and pretransfer periods. Secondary outcomes included the proportion of patients with PDC of greater than 80%, medication adherence by drug group, shipment volumes, number of medications per shipment, and the mean copay per medication. In this study of 163 patients, use of a specialty pharmacy care model led to a significant increase of 7.0% in mean PDC, a significant increase in the percentage of patients with PDC of greater than 80%, a significant decrease in the number of shipments per 30 days per patient, a significant increase in the number of medications included per shipment, and a significant reduction in the mean copay per medication. The findings in this study suggest that the application of the specialty pharmacy care model to nonspecialty pharmacy patients may improve medication adherence, decrease the number of shipments per patient sent from the pharmacy, and reduce patient copays.

Young adult preferences for digital health interventions to support adherence to inhaled corticosteroids in asthma: a qualitative study

ABSTRACT Objective: Adherence to inhaled corticosteroids (ICS) among young adults living with asthma is low and in need of appropriate intervention. Digital health interventions (DHIs) have demonstrated potential to improve ICS adherence; however, young adult preferences for these DHIs and how their use could support adherence in this population remain understudied. Therefore, this study aimed to explore young adult preferences for ICS adherence supports and potential DHI features to deliver these supports, in order to improve adherence behaviour throughout this critical developmental stage of the lifespan. Methods: Qualitative, semi-structured interviews were conducted with 13 young adults living with asthma. Analysis followed an inductive, reflexive thematic approach. Results: Participant’s age ranged from 18 to 30 years (M = 24.7; 8 female). Three themes were developed from the analysis: ‘Enabling young adults to find their ‘own way of knowing', ‘Support for making a habit of adherence’, and ‘Providing accessible information’ which included the sub-themes: ‘Education on asthma self-management and medication’, ‘Self-monitoring information’ and ‘Personal feedback on outcomes of adherence’. Suggested features to deliver these supports included a medication and prescription refill reminder, adherence charts, symptom and trigger monitoring, rewards for adherence, visual representations of lungs demonstrating the impact of adherence and lung function monitoring. Conclusion: DHIs may offer an appropriate solution to improve suboptimal adherence to ICS in young adults. However, it is crucial that young adult preferences for adherence supports and features are integrated into these interventions in order to optimise engagement and support adherence behaviour in this population.

Pharmacists\u2019 and patients\u2019 perceptions about the importance of pharmacist services types to improve medication adherence among patients with diabetes in Indonesia

BackgroundVarious pharmacist services are available to improve medication adherence, including consultation, brochure, etc. Challenges arise on which services are best implemented in practice. Knowledge about patients’ and pharmacists’ preferences can help to prioritize services. This study explores the pharmacists’ and patients’ perceptions about the importance of pharmacist services to improve medication adherence among patients with diabetes in Indonesia.MethodsThis questionnaire-based cross-sectional study involved adult outpatients with diabetes type 2 and pharmacists from community health centers (CHCs) and hospitals in Surabaya, Indonesia. Random sampling was used to identify 57 CHCs in the study. In addition, based on convenient sampling, three hospitals participated. All pharmacists working at the CHCs and hospitals, who were willing to participate, were included in the study. For patients, minimum sample size was calculated using Slovin’s formula.Patients and pharmacists were asked to rank five pharmacist service types (consultation, brochure/leaflet, patient group discussion, medication review, and phone call refill reminder) according to their importance to improve medication adherence. A face validity test of the self-developed questionnaire was conducted before the data collection. Rank ordered probit models were estimated (STATA 15th software).ResultsA total of 457 patients from CHCs, 579 patients from hospitals, and 99 pharmacists from both medical facilities were included. Consultation (CHC patients 56.0% vs hospital patients 39.7% vs pharmacists 75.2%) and brochure (CHC patients 23.2% vs hospital patients 27.5% vs pharmacists 11.9%) were the most preferred pharmacist services. Patients with experience getting medication information from pharmacists valued consultation higher than brochure and patient group discussions. Older patients ranked a brochure higher than other services. Patients without formal education in CHCs had a lower probability of giving a high rank to a brochure to improve medication adherence. There was significant positive correlation between the ranking of phone call refill reminder and medication review (0.6940) for patients in CHCs.ConclusionFor both patients and pharmacists, consultation, brochure, and group discussion were the highest-ranked services. Education, age, experience with pharmacist services, and medical facility features need to be considered when evaluating which pharmacist services to implement in Indonesia.

Access to Technology and Preferences for an mHealth Intervention to Promote Medication Adherence in Pediatric Acute Lymphoblastic Leukemia: Approach Leveraging Behavior Change Techniques.

BackgroundSuboptimal adherence to 6-mercaptopurine (6-MP) is prevalent in pediatric acute lymphoblastic leukemia (ALL) and associated with increased risk of relapse. Rapid uptake of personal technology makes mobile health (mHealth) an attractive platform to promote adherence.ObjectiveStudy objectives were to examine access to mobile technology and preferences for an mHealth intervention to improve medication adherence in pediatric ALL.MethodsA cross-sectional survey was administered in oncology clinic to parents of children with ALL as well as adolescents and young adults (AYAs) with ALL receiving maintenance chemotherapy.ResultsA total of 49 parents (median age [IQR] 39 [33-42] years; female 76% [37/49]) and 15 patients (median age [IQR] 17 [16-19]; male 80% [12/15]) participated. All parents and AYAs owned electronic tablets, smartphones, or both. Parents’ most endorsed mHealth app features included a list of medications (71%, 35/49), information about 6-MP (71%, 35/49), refill reminders (71%, 35/49), and reminders to take 6-MP (71%, 35/49). AYAs' most endorsed features included refill reminders (73%, 11/15), reminders to take 6-MP (73%, 11/15), and tracking 6-MP (73%, 11/15).ConclusionsParents and AYAs reported ubiquitous access to mobile technology and strong interest in multiple adherence-specific mHealth app features. Parents and AYAs provided valuable insight into preferred features for a multifunctional behavioral intervention (mHealth app) to promote medication adherence in pediatric ALL.

Interventions to Enhance Medication Adherence in Hypertensive Patients: A Systematic Review

Hypertension being a major risk factor for Cardio- and Cerebro- Vascular diseases could be termed as silent killer that has affected over 1.56 billion patients per annum. It is a silent killer in both the developed as well as developing nations of the world. Currently about half of people with hypertension (HTN) have uncontrolled blood pressure due to Lack of medication adherence. This paper elaborates the different interventions intended to enhance medication adherence in Hypertensive patients by means of systematic review, thereby broadening the scope of knowledge associated with Medication adherence interventions. In this systematic review authors have tried to collect research evidences of various popular approaches which are being used in the current practices namely, Self- monitoring, Patient counselling/ Patient education (Personalized telephone counselling sessions with health educators), Medication regimen management (Using combination pills to reduce number of pills patients taken daily), Medication taking reminders such as refill reminder calls or use of electronic drug monitors for monitoring and reminding, Pill count, Pill box, Smart app, Audio and Video tape. Traditional self-monitoring patients showed lower medication adherence, tele-nursing was originating to be further effective compared to self-monitoring method. Triple combination pill and fixed dose achieved a target BP. Cost of the monitors and the challenges of integrating their adherence data into clinical care are the barriers to their routine use outside of the research setting in electronically monitored adherence. The use of pill boxes resulted in clinically considerable reductions in systolic BP as well as an increased number of patients meeting prescribed BP goals.

Impact of Pharmacy Type on HIV Viral Suppression: A Retrospective Cross-Sectional Cohort Study.

BackgroundPeople with HIV (PWH) use various pharmacy types beyond traditional local pharmacies. Some specialized pharmacies offer additive adherence services such as refill reminders, expedited delivery, and adherence packaging.MethodsThis single-center, retrospective cohort study evaluated the impact of pharmacy type on the gain or loss of HIV viral suppression (VS; HIV RNA ≤50 copies/mL). Patients (≥19 years) were categorized by VS and pharmacy type: HIV-specialized (additive adherence/delivery services) vs traditional (without adherence/delivery services). Fisher exact tests examined the effect of pharmacy type on differences in VS between years, and logistic regression models identified possible predictors of gaining or losing VS.ResultsDuring 2017–2018, no differences were observed for the gain or loss of VS across pharmacy types (VS gain vs continued viremia, P = .393; VS loss vs continued VS, P = .064). Predictors for the gain of VS included antiretroviral therapy adherence as percentage of days covered (PDC; adjusted odds ratio [aOR], 1.05; P < .001) and Federal Poverty Level 100%–138% (FPL; aOR, 0.17; P = .032). Predictors for the loss of VS included use of protease inhibitor (aOR, 2.85; P = .013), ≥1 other illicit substance including tobacco (aOR, 2.96; P = .024), PDC (aOR, 0.95; P < .001), FPL 139%–200% (aOR, 0.09; P = .031), and CD4 >200 cells/ccm (aOR, 0.19; P = .013).ConclusionsThe gain or loss of VS among PWH in this retrospective cohort was not impacted by pharmacy transitions within the 2-year study period. However, PDC, FPL, illicit substance use, protease inhibitor use, and CD4 >200 cells/ccm were identified as factors associated with changes in VS.

A new age intervention to support medication adherence.

Adherence to pharmacological treatments is a complex behaviour which is influenced by a number of factors throughout a person's medication use journey. No single intervention has yet been shown to effectively address non-adherence long term. Technology, which can support a multifaceted intervention targeted to the needs of a person, may present a feasible solution to optimise adherence. Technological interventions such as mobile applications (apps) have shown early promise, increasing medication adherence rates and providing health care practitioners with an opportunity to monitor and measure adherence. Some of their features include providing informational messages, saving prescription details and sending refill reminders. Their inability to address patient specific factors across the three phases of adherence (initiation, implementation and discontinuation) limit their usefulness in clinical practice. We propose recommendations to guide the design of digital interventions that can support adherence. Interventions should be individualised to address patient specific factors that affect adherence to medications; the features should support individuals across all three phases of adherence. Interventions must integrate within existing prescriber and dispensing software and interconnect all members of an individual's healthcare team. Finally, to ensure optimal outcomes for the individual, all digital interventions should inform the person about why adherence is necessary.

A randomized clinical trial of an interactive voice response and text message intervention for individuals with hypertension.

Interactive voice response and text message (IVR-T) technology may improve hypertension control in under-resourced settings. We conducted a randomized clinical trial to determine whether an IVR-T intervention would improve blood pressure (BP), medication adherence and visit keeping among adults with hypertension from multiple racial and ethnic groups in primary care at an Urban Indian Health Organization in Albuquerque, New Mexico. Two hundred and ninety-five participants were randomly assigned to IVR-T (N=148) or to usual care (N=147). The IVR-T arm received reminders for clinic visits, messages to reschedule missed clinic visits, monthly medication refill reminders, weekly motivational messages, and a blood pressure cuff. The usual care arm received no messages. The primary outcome was change in systolic BP (SBP) between baseline and 12months. Secondary outcomes included change in SBP between baseline and 6months, change in diastolic BP (DBP) at 6 and 12months, self-reported adherence at 6months, and the proportion of missed primary care clinic appointments. The intervention did not affect SBP or DBP at 6 or 12months. The 12-month change in SBP/DBP was 1.66/1.10mmHg in usual care and 0.23/1.34mmHg in the intervention group (P values=.57 and .88, respectively). Self-reported medication adherence improved comparably in both groups, and there was no difference in percentage of kept visits. Several features of study design, clinic operations, and data transfer were barriers to demonstrating effectiveness.

The Effect of an Integrated Health System Specialty Pharmacy on HIV Antiretroviral Therapy Adherence, Viral Suppression, and CD4 Count in an Outpatient Infectious Disease Clinic.

Adherence to antiretroviral (ARV) therapy is critical in order to achieve and maintain viral suppression and improve immune function. Clinical pharmacists and pharmacies focused on human immunodeficiency virus (HIV) have demonstrated the ability to increase ARV medication adherence and subsequently have a positive effect on these lab markers. To evaluate the effect of an integrated health system specialty pharmacy service with a clinic-embedded, HIV-trained pharmacist and pharmacy technician on ARV medication adherence rate, viral load, and CD4 count. This was a single-center, retrospective cohort study conducted from August 7, 2017, to June 30, 2018, at an indigent outpatient infectious disease clinic within Atrium Health (AH), a not-for-profit health system based in Charlotte, NC. The intervention group (opt-in group) received HIV patient care that involved the health system specialty pharmacy service. Once a patient was enrolled in the specialty pharmacy service, medication reconciliation was completed by the pharmacist, financial assistance and prior authorizations were completed if needed; prescriptions were delivered to the patient; and monthly refills calls were conducted to assess adherence, tolerability, and medication changes. The control group (opt-out group) received HIV patient care that did not incorporate the health system specialty pharmacy. The primary endpoints were medication adherence, viral suppression, and CD4 counts. Within-group comparisons from baseline to follow-up were made along with group-to-group comparisons. Adherence was calculated using medication possession ratio. For those patients using Atrium Health Specialty Pharmacy Service (AH SPS; n = 46), the overall median adherence rate was higher at 100% versus only 94% for those patients (n = 50) that opted out of the service (P < 0.01). All but 3 patients (21.7% at baseline vs. 6.5% at follow-up, P = 0.03) using AH SPS reached viral suppression, and all but 1 had improved immune function with a CD4 count of 200 or greater by the end of the observation period (P = 0.03). The change in viral suppression and CD4 count of 200 or greater was not statistically improved between baseline and follow-up in those opting out of using AH SPS. When comparing the 2 groups at reaching these endpoints, there was no statistically significant difference in viral suppression and CD4 count. AH SPS was able to demonstrate improved ARV adherence in those patients using an integrated specialty pharmacy with an embedded pharmacy team, coordinated monthly medication delivery, and refill reminder and adherence calls. This in turn led to improved viral suppression and immune markers by the end of the observation window for patients using AH SPS. No outside funding supported this study. The authors have nothing to disclose.

Usability and Utility of a Mobile App to Improve Medication Adherence Among Ambulatory Care Patients in Malaysia: Qualitative Study.

BackgroundTo date, several medication adherence apps have been developed. However, the existing apps have been developed without involving relevant stakeholders and were not subjected to mobile health app guidelines. In addition, the usability and utility of these apps have not been tested with end users.ObjectiveThis study aimed to describe the usability and utility testing of a newly developed medication adherence app—Med Assist—among ambulatory care patients in Malaysia.MethodsThe Med Assist app was developed based on the Theory of Planned Behavior and the Nielson usability model. Beta testing was conducted from March to May 2016 at a primary care clinic in Kuala Lumpur. Ambulatory care patients who scored ≥40% on the electronic health literacy scale, were aged ≥21 years, and were taking two or more long-term medications were recruited. Two rounds of in-depth interviews were conducted with each participant. The first interview, which was conducted upon participant recruitment, was to assess the usability of Med Assist. Participants were asked to download Med Assist on their phone and perform two tasks (register themselves on Med Assist and enter at least one medication). Participants were encouraged to “concurrently think aloud” when using Med Assist, while nonverbal cues were observed and recorded. The participants were then invited for a second interview (conducted ≥7 days after the first interview) to assess the utility of Med Assist after using the app for 1 week. This was done using “retrospective probing” based on a topic guide developed for utilities that could improve medication adherence.ResultsUsability and utility testing was performed for the Med Assist app (version P4). A total of 13 participants were recruited (6 men, 7 women) for beta testing. Three themes emerged from the usability testing, while three themes emerged from the utility testing. From the usability testing, participants found Med Assist easy to use and user friendly, as they were able to complete the tasks given to them. However, the details required when adding a new medication were found to be confusing despite displaying information in a hierarchical order. Participants who were caregivers as well as patients found the multiple-user support and pill buddy utility useful. This suggests that Med Assist may improve the medication adherence of patients on multiple long-term medications.ConclusionsThe usability and utility testing of Med Assist with end users made the app more patient centered in ambulatory care. From the usability testing, the overall design and layout of Med Assist were simple and user friendly enough for participants to navigate through the app and add a new medication. From the participants’ perspectives, Med Assist was a useful and reliable tool with the potential to improve medication adherence. In addition, utilities such as multiple user support and a medication refill reminder encouraged improved medication management.

Refill Reminder Preference and Inhaled Corticosteroid Adherence Among Patients with Asthma

Refill reminders can help patients improve adherence to inhaled corticosteroid (ICS) therapy. However, little is known about patient preferences for reminder type or whether patients who express a preference differ from patients who do not. To describe patient preferences for ICS prescription refill reminder type and to compare baseline ICS therapy adherence, measured as proportion of days covered (PDC) 1 year before initiating preference-based reminders, between patients who did and did not express a preference. This substudy within a randomized multi-intervention study was conducted at Kaiser Permanente Colorado. Adults with asthma randomized to intervention were offered the opportunity to choose text, telephone, or email reminders. Patients who did and did not provide a preference were compared by baseline characteristics using log-binomial models. The primary outcomes were reminder preference and type. A total of 1497 of 4545 patients (32.9%) expressed a preference; 789 (52.7%) chose text. The adjusted relative risk (aRR) of not providing a preference increased with decreasing PDC (PDC of 0.50 to < 0.80: aRR, 1.14; 95% confidence interval [CI], 1.04-1.25; PDC < 0.5: aRR, 1.76; 95% CI, 1.59-1.95) compared with patients with a PDC of 0.80 or greater. Among patients who expressed a preference, text reminders were preferred. Patients who expressed a preference had higher baseline adherence. Further research is needed to determine whether expressing a preference for a refill reminder type is itself associated with adherence. Given that offering the opportunity to choose a reminder type only engaged a subset of patients, further work is needed to understand how best to leverage technology-enabled communication outreach to help patients optimize adherence.

Digital Communication Technology: Does Offering a Choice of Modality Improve Medication Adherence and Outcomes in a Persistent Asthma Population?

Use of digital communication technology has shown potential to improve asthma adherence and outcomes. Few studies have looked at patient preference around mode of medication reminders used to improve and maintain asthma medication adherence. To determine if, in a population already receiving automated medication reminders, offering a choice for preferred mode of reminder (text, email, phone) would improve their adherence and asthma outcomes over a 1-year period. This was a pragmatic, randomized controlled trial conducted at Kaiser Permanente Colorado involving 7522 adult patients with persistent asthma. Study patients were randomized to receive usual care or their choice of medication reminder. Differences between the 2 groups in both medication adherence and asthma outcomes were then assessed over the following year. Only 30% of those offered a choice of medication reminder modality responded by making a choice, with 52% preferring text messaging. There was less of a decrease in adherence rate over the 1-year period in those who made a choice regarding the mode of medication refill reminder. There was no difference in asthma outcomes between those who did make a choice compared with those who did not make a choice regarding the mode of medication refill reminder. In a patient population already receiving medication reminders, offering a choice about what type of technology-enabled asthma medication reminder patients wanted did not improve outcomes but did enable a subgroup to better maintain their medication adherence.

Impact of Social Determinants of Health and Demographics on Refill Requests by Medicare Patients Using a Conversational Artificial Intelligence Text Messaging Solution: Cross-Sectional Study.

BackgroundNonadherence among patients with chronic disease continues to be a significant concern, and the use of text message refill reminders has been effective in improving adherence. However, questions remain about how differences in patient characteristics and demographics might influence the likelihood of refill using this channel.ObjectiveThe aim of this study was to evaluate the efficacy of an SMS-based refill reminder solution using conversational artificial intelligence (AI; an automated system that mimics human conversations) with a large Medicare patient population and to explore the association and impact of patient demographics (age, gender, race/ethnicity, language) and social determinants of health on successful engagement with the solution to improve refill adherence.MethodsThe study targeted 99,217 patients with chronic disease, median age of 71 years, for medication refill using the mPulse Mobile interactive SMS text messaging solution from December 2016 to February 2019. All patients were partially adherent or nonadherent Medicare Part D members of Kaiser Permanente, Southern California, a large integrated health plan. Patients received SMS reminders in English or Spanish and used simple numeric or text responses to validate their identity, view their medication, and complete a refill request. The refill requests were processed by Kaiser Permanente pharmacists and support staff, and refills were picked up at the pharmacy or mailed to patients. Descriptive statistics and predictive analytics were used to examine the patient population and their refill behavior. Qualitative text analysis was used to evaluate quality of conversational AI.ResultsOver the course of the study, 273,356 refill reminders requests were sent to 99,217 patients, resulting in 47,552 refill requests (17.40%). This was consistent with earlier pilot study findings. Of those who requested a refill, 54.81% (26,062/47,552) did so within 2 hours of the reminder. There was a strong inverse relationship (r10=−0.93) between social determinants of health and refill requests. Spanish speakers (5149/48,156, 10.69%) had significantly lower refill request rates compared with English speakers (42,389/225,060, 18.83%; X21 [n=273,216]=1829.2; P<.001). There were also significantly different rates of refill requests by age band (X26 [n=268,793]=1460.3; P<.001), with younger patients requesting refills at a higher rate. Finally, the vast majority (284,598/307,484, 92.23%) of patient responses were handled using conversational AI.ConclusionsMultiple factors impacted refill request rates, including a strong association between social determinants of health and refill rates. The findings suggest that higher refill requests are linked to language, race/ethnicity, age, and social determinants of health, and that English speakers, whites, those younger than 75 years, and those with lower social determinants of health barriers are significantly more likely to request a refill via SMS. A neural network–based predictive model with an accuracy level of 78% was used to identify patients who might benefit from additional outreach to narrow identified gaps based on demographic and socioeconomic factors.

Two-Way Clinical Messaging in a CML Specialty Pharmacy Service Model.

Adherence to treatment is correlated with treatment success in chronic myeloid leukemia (CML). CVS Specialty explored novel methods to improve adherence in this population to ensure optimal adherence and lower the risk of unsuccessful treatment. One novel program explored involved an interactive 2-way clinical messaging technology that coaches patients with adherence and knowledge about taking their treatment and managing their conditions. Clinical secure messaging is a 2-way messaging program distinct from the 1-way refill reminders and order status messages that patients were receiving if opted into the messaging program. To assess the effect on adherence of 2-way clinical messaging in a CML population treated with tyrosine kinase inhibitors (TKIs) compared with patients enrolled in 1-way refill reminders. A retrospective cohort study was conducted using prescription claims data. Patients new to TKI therapy and enrolled in at least 1-way messaging were identified and divided into control and study cohorts based on clinical messaging enrollment status. Participants were followed for 365 days after their first fill. Adherence outcomes were defined by medication possession ratio (MPR), length of therapy, first fill drop-off rate, and gap days between refills. Optimal adherence was defined as an MPR ≥ 85%. Patients receiving clinical messaging had on average a 7.64% higher MPR score (MPR: 73.94% vs. 66.30%) compared with the control arm (P = 0.0063). This translates to 22% more patients being optimally adherent while exposed to clinical messaging (P = 0.022). Patients in the exposed group had a mean 32-day increase in average length of therapy compared with the control group (243 days vs. 275 days, P = 0.0043), potentially driving an increase in adherence. Additional drivers included a 5.4 percentage point reduction in first fill drop-off rates (4.66% vs. 10.04%, P = 0.0149). Persistency after 12 months was similar between the study arms (41%). Two-way clinical messaging positively affected adherence outcomes in a CML population. This effect was in addition to 1-way refill reminders and order status messages. The nature of the clinical content encourages further investigation into this novel execution of adherence coaching and counseling through a digital platform.
