Medication adherence among homeless patients: A pilot study of cell phone effectiveness

Escitalopram population pharmacokinetics and remedial strategies based on CYP2C19 phenotype

BACKGROUND AND PURPOSE

CYP2C19 is a key factor influencing escitalopram (SCIT) exposure. However, different studies reported various results. This study aims to develop a population pharmacokinetic (popPK) model characterizes the disposition of SCIT in the Chinese population. Based on the popPK model, the study simulates non-adherence scenarios and proposes remedial strategies to facilitate SCIT personalized therapy.

METHODS

Nonlinear mixed-effects modeling using data from two Chinese bioequivalence studies was employed. Monte-Carlo simulation was used to explore non-adherence scenarios and propose remedial strategies based on the proportion of time within the therapeutic window.

RESULTS

Results showed that a one-compartment model with transit absorption and linear elimination described the data well, CYP2C19 phenotypes and weight were identified as significant covariates impacting SCIT exposure. Patients were recommended to take the entire delayed dose immediately if the delay time was no >12 h, followed by the regular regimen at the next scheduled time. When there is one or two doses missed, taking a double dose immediately was recommended to the CYP2C19 intermediate and extensive population, and a 1.5-fold dose was recommended to the CYP2C19 poor metabolizers with the consideration of adverse effects.

LIMITATION

All samples were derived from the homogenized Chinese healthy population for model building, which may pose certain constraints on the ability to identify significant covariates, such as age.

CONCLUSION

The study highlights the importance of considering patient characteristics for personalized medication and offers a unique perspective on utilizing the popPK repository in precision dosing.

A systematic review of approaches to improve medication adherence in homeless adults with psychiatric disorders

Introduction

Medication non-adherence is a significant problem among homeless individuals with psychiatric disorders in the United States. We conducted a systematic review to identify strategies to improve psychiatric medication adherence among homeless individuals with psychiatric disorders, including substance use disorders.

Methods

We searched seven databases (MEDLINE, Embase, PsychInfo, Scopus, Web of Science, CDSR, and CENTRAL) and screened 664 studies by title and abstract followed by full-text review. Our inclusion criteria were studies that: involved an intervention for homeless adults with psychiatric disorders, reported a quantitative outcome of medication adherence, and were published in English in a peer-reviewed journal. We rated the relative effectiveness of strategies described in each study using a self-designed scale.

Results

Eleven peer-reviewed studies met criteria for inclusion in this review. Within these studies, there were seven different approaches to improve medication adherence in this population. Three studies were randomized controlled trials (RCTs) and the remaining were observational studies. Outpatient interventions included Assertive Community Treatment, Cell Phone-Assisted Monitoring, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Homeless-Designated Pharmacy Clinics. Residential, shelter-based, and inpatient interventions included use of the Housing First model, Modified Therapeutic Communities, and Homeless-Designated Inpatient Care. The approaches described in four of the eleven studies were rated as scoring a 3 or higher on a 5-point scale of effectiveness in improving medication adherence; none received 5 points.

Discussion

The interventions with the strongest evidence for improving medication adherence in this population were Assertive Community Treatment, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Housing First. Overall, studies on this topic required more rigor and focus on medication adherence as an outcome in this population. This review highlights several promising strategies and the need for larger RCTs to determine effective and diverse ways to improve medication adherence among homeless adults with psychiatric disorders.

Digital health interventions to improve adherence to oral antipsychotics among patients with schizophrenia: a scoping review

OBJECTIVES

To assess the current evidence on the potential of digital health interventions (DHIs) to improve adherence to oral antipsychotics among patients with schizophrenia by assessing the methodologies, feasibility and effectiveness of DHIs as well as the perceptions of relevant stakeholders.

DESIGN

The scoping review was conducted based on the methodologies outlined by Levac et al and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines.

DATA SOURCES

PubMed, Embase, Web of Science, Scopus, CINAHL, PsycINFO and the Cochrane Library were searched in August 2023 to identify relevant publications from the previous decade.

ELIGIBILITY CRITERIA

Studies published in English focused on improving medication adherence among adult patients with schizophrenia or schizoaffective disorder via DHIs were selected. Protocols, editorials, comments, perspectives, reviews, correspondence and conference abstracts were excluded.

DATA EXTRACTION AND SYNTHESIS

The extracted data included general information about the study, framework, participants, features and strategies of DHIs, measurement tools for adherence used, and main findings.

RESULTS

In total, 64 studies were included in the qualitative synthesis. Features used in DHIs to improve medication adherence included phone calls, text messages, mobile apps, sensors, web-based platforms and electronic devices. Strategies included medication reminders and monitoring, providing medication-related information and suggestions, other illness management suggestions and individual support. Texting and mobile apps were commonly used as medication reminders and monitoring methods. Additionally, the use of sensors combined with other digital technologies has garnered significant attention. All the interventions were considered acceptable and feasible, and several were assessed in pilot trials. Preliminary findings suggest that DHIs could enhance medication adherence in patients with schizophrenia. However, further validation of their effectiveness is required.

CONCLUSION

DHIs are a promising approach to enhancing medication adherence among patients with schizophrenia. Future interventions should be interactive, focusing on user preference, experience and privacy.

Attending to the Mental Health of People Who Are Homeless by Mobile Telephone Follow-Up: A Systematic Review

BACKGROUND

More than 20% of the world's population has no decent or suitable home. People who are homeless have more health problems than the rest of the population, especially mental health-type problems. The main objective of this study was to identify follow-up interventions by using mobile telephones to improve the mental health of people who are homeless and to analyze their efficiency.

METHODS

To do so, a systematic review was carried out in the Web of Science, PubMed, Scopus, Ebscohost, and PsyInfo databases.

RESULTS

Studies conclude that mobile phone use is a suitable means to improve adherence to medication and the mental health of the homeless. However, significant attempts to demonstrate health benefits by means of reliable and valid instruments that supplement qualitative satisfaction and feedback instruments appear to be lacking.

CONCLUSIONS

The literature about mental health benefits through technology for people who are homeless is scarce and shows methodological limitations that can lead to failure when setting up methodologies in clinical practice.

[Health Service Utilization by Homeless Persons: Analysis of the Role of Enabling Factors, Pain and Gender using the Gelberg-Andersen Model]

The aim of the study was to find factors that influence health service utilization by homeless people. In a field study, a sample of 51 homeless men and 47 homeless women in the German county of Baden-Württemberg participated in face-to-face-interviews with a questionnaire designed for this study. Analyses were performed using multiple logistic regression models. Variables were organized using the Gelberg-Andersen Behavioral Model for Vulnerable Populations. Satisfied subsistence needs (OR 1.33, 95%-CI [1.03-1.72] regarding utilization of vaccinations), a stable source of primary care (OR 12.2 [1.81-82] regarding utilization of early detection examinations; quasi-complete separation regarding use of GP services) social networks (OR 2.9 [1.13-7.5] regarding utilisation of early detection examinations; OR 0.63 [0.41-0.98] regarding emergency department visits) and technological ressources (OR 2.2 [1.13-4.4] regarding use of GP services) had a positive influence on the pattern of health service utilization. Pain was correlated with more emergency department visits (OR 1.72 [1.22-2.4]) and hospitalizations (OR 1.66 [1.19-2.3]). The results showed differences between homeless men and women. The factors of influence found in this study should be addressed in the care of homeless persons. Integration of social care into the regular health care system is necessary for early detection and treatment of complex social and medical needs of vulnerable populations. This requires interprofessional approaches in medical education and training focussing on the situation of vulnerable populations and on social determinants of health.

The Health Needs of Regionally Based Individuals Who Experience Homelessness: Perspectives of Service Providers

The bidirectional relationship between homelessness and poor health and the barriers that individuals who experience homelessness face when trying to access healthcare are well documented. There is, however, little Australian research exploring the situation of individuals who experience homelessness in regional contexts and, moreover, from the perspective of service providers. A qualitative descriptive methodology underpinned this study, with in-depth semi-structured interviews being conducted with 11 service providers to identify barriers to care faced by people who experience homelessness and barriers that service providers themselves experience in supporting this population. The key barriers identified were client-level barriers: living day-by-day, financial, health literacy, mental health conditions, behaviour, safety and stigma; provider-level barriers: few bulk-billing doctors, fragmented services, limited resources, negative past experiences with healthcare; and system level barriers: transportation, over-stretched healthcare services. The combined impact of these barriers has significantly contributed to the desperate situation of people experiencing homelessness in Launceston. This situation is likely replicated in other regional populations in Australia. Given that individuals experiencing homelessness have higher rates of every measure in health inequality, steps need to be taken to reduce barriers, and a standardised approach to health care urgently needs to be implemented by governments at the state and national level to improve the health of regionally based individuals experiencing homelessness.

Crossing the digital divide: a veteran affairs program to distribute video-enabled devices to patients in a supportive housing program

Objective

Evaluate an initiative to distribute video-enabled tablets and cell phones to individuals enrolled in Veterans Health Affairs supportive housing program during the COVID-19 pandemic.

Materials and Methods

In September 2020, individuals in the Veteran Health Affairs (VA) Housing and Urban Development-VA Supportive Housing (HUD-VASH) program were offered either a video-enabled tablet or cellphone to support their communication and health care engagement needs. We examined sociodemographic and clinical characteristics of device recipients, and compared engagement in in-person, telephone, and video-based visits (categorized as primary care, specialty care, rehabilitation, HUD-VASH, mental health care, and other) for 6 months prior to (March 1, 2020–August 31, 2020) and following (September 1, 2020–July 30, 2021) device receipt.

Results

In total, 5127 Veterans received either a tablet (n = 4454) or a cellphone (n = 673). Compared to the 6 months prior to device receipt, in the 6 months following receipt, in-person and video engagement increased by an average of 1.4 visits (8%) and 3.4 visits (125%), respectively, while telephone engagement decreased (−5.2 visits; −27%). Both tablet and cellphone recipients had increased in-person visits (+1.3 visits [8%] and +2.1 visits [13%], respectively); while tablet users had a substantially larger increase in video-based engagement (+3.2 visits [+110%] vs. +0.9 [+64%]). Similar trends were noted across all assessed types of care.

Discussion

Providing video-enabled devices to Veterans in a supportive housing program may facilitate engagement in health care.

Conclusions and Relevance

VA’s device distribution program offers a model for expanding access to health-related technology and telemedicine to individuals in supportive housing programs.

In September of 2020, the Veteran’s Health Affairs (VA) initiated a program to distribute video-enabled tablets and cellphones to Veterans who were enrolled in the Housing and Urban Development-VA Supportive Housing (HUD-VASH) program. The goal of this program was to maintain communication and health care engagement during the pandemic. After receiving either a tablet or cellphone, we compared in-person, telephone, and video-based engagement among the 4454 tablet recipients and the 673 cellphone recipients. We found in the 6 months following receipt, that overall in-person and video engagement increased by an average of 1.4 visits (8%) and 3.4 visits (125%), while telephone engagement decreased (−5.2 visits; −27%). Both tablet and cellphone recipients had increased in-person visits (+1.3 visits [8%] and +2.1 visits [13%], respectively); while tablet users had a substantially larger increase in video-based engagement (+3.2 visits [+110%] vs. +0.9 [+64%]). This study suggests that providing video-enabled devices to Veterans in a supportive housing program may facilitate engagement in health care.

Development and Initial Evaluation of a Nurse-Led Healthcare Clinic for Homeless and At-Risk Populations in Tasmania, Australia: A Collaborative Initiative

People who are homeless experience significantly poorer health than the general population and often face multifaceted challenges engaging with public healthcare services. Mission Health Nurse-led Clinic (MHNC) was established in 2019 to meet the healthcare needs of this marginalised population in Launceston, Tasmania. This study examines barriers to healthcare access amongst individuals who experience homelessness, client and staff perceptions of the MHNC services and explored opportunities for service expansion. Descriptive statistics were drawn from administrative data, and all interviews were thematically analysed. A total of 426 presentations were reported for 174 individuals experiencing homelessness over 26 months. The median client age was 42 years and 60.9% were male; A total of 38.5% were homeless or lived in a supported accommodation. The predominant reasons for clinic visits included prescription requests (25.3%) and immunisations (20.1%). A total of 10 clients and 5 City Mission staff were interviewed with three themes emerging from the findings: personal vulnerability, disconnectedness and acceptability of the MHNC. The MHNC services were reported to be highly appreciated by all clients. Mental health and allied health, extra operating hours and maintaining the flexibility of walk-in appointments were suggested as expansion areas for the service and were highlighted as ways to increase engagement for improved health outcomes. Continued partnerships with interprofessional primary healthcare providers would contribute to addressing unmet healthcare needs in this vulnerable population.

GPS Mobile Health Intervention Among People Experiencing Homelessness: Pre-Post Study

BACKGROUND

People experiencing homelessness are at risk for gaps in care after an emergency department (ED) or hospital visit, which leads to increased use, poor health outcomes, and high health care costs. Most people experiencing homelessness have a mobile phone of some type, which makes mobile health (mHealth) interventions a feasible way to connect a person experiencing homelessness with providers.

OBJECTIVE

This study aims to investigate the accuracy, acceptability, and preliminary outcomes of a GPS-enabled mHealth (GPS-mHealth) intervention designed to alert community health paramedics when people experiencing homelessness are in the ED or hospital.

METHODS

This study was a pre-post design with baseline and 4-month postenrollment assessments. People experiencing homelessness, taking at least 2 medications for chronic conditions, scoring at least 10 on the Patient Health Questionnaire-9, and having at least 2 ED or hospital visits in the previous 6 months were eligible. Participants were issued a study smartphone with a GPS app programmed to alert a community health paramedic when a participant entered an ED or hospital. For each alert, community health paramedics followed up via telephone to assess care coordination needs. Participants also received a daily email to assess medication adherence. GPS alerts were compared with ED and hospital data from the local health information exchange (HIE) to assess accuracy. Paired t tests compared scores on the Patient Health Questionnaire-9, Medical Outcomes Study Social Support Survey, and Adherence Starts with Knowledge-12 adherence survey at baseline and exit. Semistructured exit interviews examined the perceptions and benefits of the intervention.

RESULTS

In total, 30 participants were enrolled; the mean age was 44.1 (SD 9.7) years. Most participants were male (20/30, 67%), White (17/30, 57%), and not working (19/30, 63%). Only 19% (3/16) of the ED or hospital visit alerts aligned with HIE data, mainly because of patients not having the smartphone with them during the visit, the smartphone being off, and gaps in GPS technology. There was a significant difference in depressive symptoms between baseline (mean 16.9, SD 5.8) and exit (mean 12.7, SD 8.2; t₁₉=2.9; P=.009) and a significant difference in adherence barriers between baseline (mean 2.4, SD 1.4) and exit (mean 1.5, SD 1.5; t₁₇=2.47; P=.03). Participants agreed that the app was easy to use (mean 4.4/5, SD 1.0, with 5=strongly agree), and the email helped them remember to take their medications (mean 4.6/5, SD 0.6). Qualitative data indicated that unlimited smartphone access allowed participants to meet social needs and maintain contact with case managers, health care providers, family, and friends.

CONCLUSIONS

mHealth interventions are acceptable to people experiencing homelessness. HIE data provided more accurate ED and hospital visit information; however, unlimited access to reliable communication provided benefits to participants beyond the study purpose of improving care coordination.

Smartphone Technology to Empower People Experiencing Homelessness: Secondary Analysis

BACKGROUND

In the United States, the number of people experiencing homelessness has continually increased over the last 3 years. Homelessness is associated with poor health, and people experiencing homelessness are often burdened with high rates of chronic and mental health conditions, functional limitations, and cognitive impairment. Despite the high burden of chronic illness and functional limitations, there is limited literature exploring self-management among homeless populations.

OBJECTIVE

This study aims to investigate how access to smartphone technology facilitates self-management, including the attainment of social needs within the context of homelessness.

METHODS

A secondary analysis of 33 exit interviews from 2 feasibility studies related to mobile health interventions among people experiencing homelessness was conducted. Iterative thematic analysis was used to identify themes representative of participants' experiences using smartphone technology.

RESULTS

Collectively, participants revealed not only how the context of homelessness constrained their ability to engage in activities necessary to self-manage health and meet social needs but also how consistent and predictable access to the tools available through a smartphone changed their behaviors and outlook. The global theme of empowered by technology was identified and defined as how having a smartphone with a plan for unlimited text, calling, data, and transportation allowed participants to navigate homelessness and facilitated self-management.

CONCLUSIONS

People experiencing homelessness used the tools on a smartphone to make decisions, take action, solve problems, and use the resources-skills necessary for fulfilling tasks required for effective self-management. Further, consistent access to smartphone technology and transportation empowered participants to meet the requirements for the attainment of social needs.

Sociodemographic Determinants of Nonadherence to Depression and Anxiety Medication among Individuals Experiencing Homelessness

Psychiatric medication nonadherence continues to be a leading cause of poor health outcomes for individuals experiencing homelessness. Identifying the sociodemographic factors that contribute to medication nonadherence may help guide strategies to care for and support this group. This study examined 200 adults with depression diagnoses and active anti-depressant prescriptions (Mage = 43.98 ± 12.08, 59.4% Caucasian, 58.5% male, 70% uninsured, 89.5% unemployed) and 181 adults with anxiety diagnoses and active anti-anxiety prescriptions (Mage = 43.45 ± 11.02, 54.4% Caucasian, 57.5% male, 66.3% uninsured, 88.9% unemployed) recruited from six homeless-serving agencies in Oklahoma City. Self-reported sociodemographic variables included: age, sex, race/ethnicity, education, monthly income, employment status, and health insurance status. Adjusted logistic regression analyses revealed that employed (OR = 4.022, CI_0.95: 1.244–13.004) and insured (OR = 2.923, CI_0.95: 1.225–6.973) participants had greater odds of depression medication nonadherence. For anxiety, being employed (OR = 3.573, CI_0.95: 1.160–11.010) was associated with greater odds of anxiety medication nonadherence, whereas having depression and anxiety diagnostic comorbidity (OR = 0.333, CI_0.95: 0.137–0.810) was associated with lower odds of anxiety medication nonadherence. Interventions aimed at facilitating accessible prescription acquisition or otherwise reducing barriers to prescription medications for employed adults, including those with health insurance, may benefit adherence, but more research is needed. Future studies would benefit from using a qualitative approach to better delineate nuanced barriers to psychiatric medication adherence.

Barriers to and Facilitators of User Engagement With Digital Mental Health Interventions: Systematic Review

Background

Digital mental health interventions (DMHIs), which deliver mental health support via technologies such as mobile apps, can increase access to mental health support, and many studies have demonstrated their effectiveness in improving symptoms. However, user engagement varies, with regard to a user’s uptake and sustained interactions with these interventions.

Objective

This systematic review aims to identify common barriers and facilitators that influence user engagement with DMHIs.

Methods

A systematic search was conducted in the SCOPUS, PubMed, PsycINFO, Web of Science, and Cochrane Library databases. Empirical studies that report qualitative and/or quantitative data were included.

Results

A total of 208 articles met the inclusion criteria. The included articles used a variety of methodologies, including interviews, surveys, focus groups, workshops, field studies, and analysis of user reviews. Factors extracted for coding were related to the end user, the program or content offered by the intervention, and the technology and implementation environment. Common barriers included severe mental health issues that hampered engagement, technical issues, and a lack of personalization. Common facilitators were social connectedness facilitated by the intervention, increased insight into health, and a feeling of being in control of one’s own health.

Conclusions

Although previous research suggests that DMHIs can be useful in supporting mental health, contextual factors are important determinants of whether users actually engage with these interventions. The factors identified in this review can provide guidance when evaluating DMHIs to help explain and understand user engagement and can inform the design and development of new digital interventions.

Interventions delivered by nurses in adult outpatient psychiatric care: An integrative review

WHAT IS KNOWN ON THE SUBJECT?: In many countries, the majority of psychiatric care is being delivered in an outpatient setting and the proportion of outpatients is increasing on a global level. Nurses are the largest workforce in psychiatric care, but their role has been said to be difficult to define. According to our knowledge, there are no previous reviews focusing on nurse-delivered interventions in the adult psychiatric outpatient setting. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This review summarizes nurse-delivered interventions identified in the research literature and describes these systematically. Analysing all the identified interventions using the Nursing Interventions Classification, we conclude that the emphasis of nurse-delivered interventions in psychiatric outpatient care is on interventions aiming at improving the functioning of both patients and their family members by building on their own strengths. These findings differ from those presented in a review on inpatient psychiatric nursing. There are several clinical trials describing nurse-delivered evidence-based treatments, such as psychoeducation for patients and their family members in the case of patients diagnosed with schizophrenia and bipolar disorder. The quality of randomized controlled trials was higher than in earlier reviews describing psychiatric nursing interventions in general or in connection with a specific patient group. Further clinical trials are needed to describe the role of nurses in the care of patients diagnosed with depression and in the use of web-based interventions. Additionally, it would be important to study what supports, and on the other hand hinders, the role of nurses in delivering evidence-based treatments at the clinical level. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurses can play a central role in responding to the growing demand for evidence-based practices in adult outpatient psychiatry, by delivering treatments for patients and family members. It is important that both nursing education and clinical practices recognize and support this role. Abstract Introduction According to our knowledge, there are no previous reviews on nurse-delivered interventions in the adult psychiatric outpatient setting. Aim To identify and systematically describe and analyse nurse-delivered interventions based on research literature. Method An integrative review. Results This review included 60 studies, of which 46 were intervention studies, including 40 clinical trials. The most common patient groups were patients diagnosed with schizophrenia and bipolar disorder. The nursing interventions described in the studies resembled a total of 68 interventions from the Nursing Interventions Classification. The treatment delivery methods varied and treatments often lacked a clear theoretical background. Implications for practice The core of nurse-delivered interventions identified in research literature in psychiatric outpatient care is on interventions aiming at improving the functioning of both patients and their family members by building on their own strengths. These findings differ from the interventions identified in a review describing nursing in the inpatient setting. There are high-quality clinical trials describing nurse-delivered treatments for patients diagnosed with schizophrenia and bipolar disorder. These include evidence-based treatments such as psychoeducation. Understanding of how these treatments are transferred in clinical practice is missing. Clinical trials describing nurse-delivered web-based interventions and interventions for patients diagnosed with depression are needed.

Descriptive study of homeless patients' perceptions that affect medication adherence

PURPOSE

Results of a study to elucidate perceptions, attitudes, and beliefs about prescribed medications held by hospitalized patients who are homeless are reported.

METHODS

A qualitative descriptive study involving semistructured interviews was conducted to gather information and characterize hospitalized homeless patients' views and attitudes regarding medication use, with a focus on medication nonadherence. Medication nonadherence has been shown to be a factor contributing to higher rates of emergency department visits, increased hospital lengths of stay, and increased healthcare costs in homeless populations. Interviews were conducted during patients' admissions to the internal medicine service of a tertiary care, inner-city hospital. Interviews were audio-recorded and transcribed. Data were analyzed using conventional qualitative content analysis to generate data-driven codes and themes.

RESULTS

Twelve interviews were conducted (median patient age, 48.5 years). Eight patients (66.7%) were living in a shelter, and 11 (91.7%) had a mental illness. Patients were prescribed a median of 4 medications at the time of hospital admission. Four themes were identified: (1) a new appreciation of medications was acquired during hospitalization, (2) medications were perceived as necessary for maintaining health, (3) there was an interest in receiving medication education, and (4) concerns were expressed regarding medication adverse effects.

CONCLUSION

In interviews conducted during hospital admission, homeless patients expressed positive perceptions about the necessity of their medications but also concerns about medication adverse effects. Interventions to improve adherence may be successful if directed toward addressing treatment-related concerns.

A text messaging-based intervention to increase physical activity among persons living in permanent supportive housing: Feasibility and acceptability findings from a pilot study

OBJECTIVE

Persons who have experienced homelessness and are living in permanent supportive housing experience high rates of health and mental health problems. Given that physical activity is associated with improved health outcomes and persons with homelessness histories report high rates of cell phone use, phone-based interventions to increase physical activity may be effective for improving health and wellbeing among persons in permanent supportive housing.

METHODS

To understand the acceptability and feasibility of a cell phone-based physical activity intervention in this population, this 6-week pilot study enrolled 13 persons living in permanent supportive housing. Participants were eligible if they had completed their final, 12-month follow-up interview in a larger, longitudinal study of persons moving into permanent supportive housing in the Los Angeles area, spoke English, and reported comorbid chronic physical and mental health conditions. For the study duration, participants wore a pedometer, received multiple weekly motivational text messages on set days (at times selected by the participant), and responded via text to weekly depression screeners and requests to report their weekly step totals, as recorded by their pedometers. Follow-up interviews asked open-ended questions about study participation and satisfaction.

RESULTS

Participants were 53 years old on average, most were female (54%), and most were African-American (62%). Changes to people's physical activity levels were limited, but participants reported increased quality of life during the intervention period. Interviews revealed that the intervention was well received and enjoyable for participants.

CONCLUSIONS

The efficacy of utilizing cell phones to improve health and wellbeing among adults living in permanent supportive housing requires further research, but these pilot findings suggest that such interventions are feasible and acceptable.

Inappropriate Use of Medication by Elderly, Polymedicated, or Multipathological Patients with Chronic Diseases

The growth of the aging population leads to the increase of chronic diseases, of the burden of multimorbility, and of the complexity polypharmacy. The prevalence of medication errors rises in patients with polypharmacy in primary care, and this is a major concern to healthcare systems. This study reviews the published literature on the inappropriate use of medicines in order to articulate recommendations on how to reduce it in chronic patients, particularly in those who are elderly, polymedicated, or multipathological. A systematic review of articles published from January 2000 to October 2015 was performed using MEDLINE, EMBASE, PsychInfo, Scopus, The Cochrane Library, and Index Medicus databases. We selected 80 studies in order to analyse the content that addressed the question under consideration. Our literature review found that half of patients know what their prescribed treatment is; that most of elderly people take five or more medications a day; that in elderly, polymedicated people, the probability of a medication error occurring is higher; that new tools have been recently developed to reduce errors; that elderly patients can understand written information but the presentation and format is an important factor; and that a high percentage of patients have remaining doubts after their visit. Thus, strategies based on the evidence should be applied in order to reduce medication errors.

Text Messaging May Engage and Benefit Adults with Type 2 Diabetes Regardless of Health Literacy Status

Background:

Technology-delivered interventions have the potential to improve diabetes self-care and glycemic control among adults with type 2 diabetes (T2D). However, patients who do not engage with interventions may not reap benefits, and there is little evidence on how engagement with mobile health interventions varies by health literacy status.

Objective:

This study explored how patients with limited health literacy engaged with and experienced Rapid Education/Encouragement and Communications for Health (REACH), a text messaging intervention designed to support the self-care adherence of disadvantaged patients with T2D. We recruited adults with T2D from federally qualified health centers and used mixed methods to examine (1) associations between users' health literacy status and their prior mobile phone use and their engagement with REACH and (2) similarities and differences in users' self-reported benefits by health literacy status.

Methods:

Participants (N = 55) completed a survey, including measures of health literacy and prior mobile phone use. For 2 weeks, participants experienced REACH, which included daily text messages promoting self-care and asking about medication adherence, and weekly text messages providing medication adherence feedback. After 2 weeks, participants completed a semi-structured telephone interview about their experiences.

Key Results:

Participants with limited health literacy were less likely to have used cell phones to access the Internet (48% vs. 90%, p = .001) or email (36% vs. 87%, p < .001), but equally as likely to have used text messaging and to respond to REACH text messages (p = .12 and p = .40, respectively) compared to participants with adequate health literacy. Participants responded to 93% of text messages on average and reported benefits of the intervention, including reminders and accountability, convenience and accessibility, and information and motivation. Participants with limited health literacy described a unique benefit of receiving social support from the intervention.

Conclusions:

Text messaging interventions may engage and benefit patients with T2D, regardless of health literacy status. Text messaging may have the potential to reduce T2D health disparities related to limited health literacy. [Health Literacy Research and Practice. 2017;1(4):e192–e202.]

Plain Language Summary:

Limited health literacy is associated with less engagement with health information technology, but there is little evidence on how engagement with text messaging interventions varies by health literacy status. This intervention engaged and benefited adults with type 2 diabetes in safety-net clinics, regardless of health literacy status. Participants with limited health literacy described a unique intervention benefit of social support.

No Digital Divide? Technology Use among Homeless Adults

Homeless adults experience increased risk of negative health outcomes, and technology-based interventions may provide an opportunity for improving health in this population. However, little is known about homeless adults' technology access and use. Utilizing data from a study of 421 homeless adults moving into PSH, this paper presents descriptive technology findings, and compares results to age-matched general population data. The vast majority (94%) currently owned a cell phone, although there was considerable past 3-month turnover in phones (56%) and phone numbers (55%). More than half currently owned a smartphone, and 86% of those used Android operating systems. Most (85%) used a cell phone daily, 76% used text messaging, and 51% accessed the Internet on their cell phone. One-third reported no past 3-month Internet use. These findings suggest that digital technology may be a feasible means of disseminating health and wellness programs to this at-risk population, though important caveats are discussed.

Automated telephone communication systems for preventive healthcare and management of long-term conditions

BACKGROUND

Automated telephone communication systems (ATCS) can deliver voice messages and collect health-related information from patients using either their telephone's touch-tone keypad or voice recognition software. ATCS can supplement or replace telephone contact between health professionals and patients. There are four different types of ATCS: unidirectional (one-way, non-interactive voice communication), interactive voice response (IVR) systems, ATCS with additional functions such as access to an expert to request advice (ATCS Plus) and multimodal ATCS, where the calls are delivered as part of a multicomponent intervention.

OBJECTIVES

To assess the effects of ATCS for preventing disease and managing long-term conditions on behavioural change, clinical, process, cognitive, patient-centred and adverse outcomes.

SEARCH METHODS

We searched 10 electronic databases (the Cochrane Central Register of Controlled Trials; MEDLINE; Embase; PsycINFO; CINAHL; Global Health; WHOLIS; LILACS; Web of Science; and ASSIA); three grey literature sources (Dissertation Abstracts, Index to Theses, Australasian Digital Theses); and two trial registries (www.controlled-trials.com; www.clinicaltrials.gov) for papers published between 1980 and June 2015.

SELECTION CRITERIA

Randomised, cluster- and quasi-randomised trials, interrupted time series and controlled before-and-after studies comparing ATCS interventions, with any control or another ATCS type were eligible for inclusion. Studies in all settings, for all consumers/carers, in any preventive healthcare or long term condition management role were eligible.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods to select and extract data and to appraise eligible studies.

MAIN RESULTS

We included 132 trials (N = 4,669,689). Studies spanned across several clinical areas, assessing many comparisons based on evaluation of different ATCS types and variable comparison groups. Forty-one studies evaluated ATCS for delivering preventive healthcare, 84 for managing long-term conditions, and seven studies for appointment reminders. We downgraded our certainty in the evidence primarily because of the risk of bias for many outcomes. We judged the risk of bias arising from allocation processes to be low for just over half the studies and unclear for the remainder. We considered most studies to be at unclear risk of performance or detection bias due to blinding, while only 16% of studies were at low risk. We generally judged the risk of bias due to missing data and selective outcome reporting to be unclear.For preventive healthcare, ATCS (ATCS Plus, IVR, unidirectional) probably increase immunisation uptake in children (risk ratio (RR) 1.25, 95% confidence interval (CI) 1.18 to 1.32; 5 studies, N = 10,454; moderate certainty) and to a lesser extent in adolescents (RR 1.06, 95% CI 1.02 to 1.11; 2 studies, N = 5725; moderate certainty). The effects of ATCS in adults are unclear (RR 2.18, 95% CI 0.53 to 9.02; 2 studies, N = 1743; very low certainty).For screening, multimodal ATCS increase uptake of screening for breast cancer (RR 2.17, 95% CI 1.55 to 3.04; 2 studies, N = 462; high certainty) and colorectal cancer (CRC) (RR 2.19, 95% CI 1.88 to 2.55; 3 studies, N = 1013; high certainty) versus usual care. It may also increase osteoporosis screening. ATCS Plus interventions probably slightly increase cervical cancer screening (moderate certainty), but effects on osteoporosis screening are uncertain. IVR systems probably increase CRC screening at 6 months (RR 1.36, 95% CI 1.25 to 1.48; 2 studies, N = 16,915; moderate certainty) but not at 9 to 12 months, with probably little or no effect of IVR (RR 1.05, 95% CI 0.99, 1.11; 2 studies, 2599 participants; moderate certainty) or unidirectional ATCS on breast cancer screening.Appointment reminders delivered through IVR or unidirectional ATCS may improve attendance rates compared with no calls (low certainty). For long-term management, medication or laboratory test adherence provided the most general evidence across conditions (25 studies, data not combined). Multimodal ATCS versus usual care showed conflicting effects (positive and uncertain) on medication adherence. ATCS Plus probably slightly (versus control; moderate certainty) or probably (versus usual care; moderate certainty) improves medication adherence but may have little effect on adherence to tests (versus control). IVR probably slightly improves medication adherence versus control (moderate certainty). Compared with usual care, IVR probably improves test adherence and slightly increases medication adherence up to six months but has little or no effect at longer time points (moderate certainty). Unidirectional ATCS, compared with control, may have little effect or slightly improve medication adherence (low certainty). The evidence suggested little or no consistent effect of any ATCS type on clinical outcomes (blood pressure control, blood lipids, asthma control, therapeutic coverage) related to adherence, but only a small number of studies contributed clinical outcome data.The above results focus on areas with the most general findings across conditions. In condition-specific areas, the effects of ATCS varied, including by the type of ATCS intervention in use.Multimodal ATCS probably decrease both cancer pain and chronic pain as well as depression (moderate certainty), but other ATCS types were less effective. Depending on the type of intervention, ATCS may have small effects on outcomes for physical activity, weight management, alcohol consumption, and diabetes mellitus. ATCS have little or no effect on outcomes related to heart failure, hypertension, mental health or smoking cessation, and there is insufficient evidence to determine their effects for preventing alcohol/substance misuse or managing illicit drug addiction, asthma, chronic obstructive pulmonary disease, HIV/AIDS, hypercholesterolaemia, obstructive sleep apnoea, spinal cord dysfunction or psychological stress in carers.Only four trials (3%) reported adverse events, and it was unclear whether these were related to the interventions.

AUTHORS' CONCLUSIONS

ATCS interventions can change patients' health behaviours, improve clinical outcomes and increase healthcare uptake with positive effects in several important areas including immunisation, screening, appointment attendance, and adherence to medications or tests. The decision to integrate ATCS interventions in routine healthcare delivery should reflect variations in the certainty of the evidence available and the size of effects across different conditions, together with the varied nature of ATCS interventions assessed. Future research should investigate both the content of ATCS interventions and the mode of delivery; users' experiences, particularly with regard to acceptability; and clarify which ATCS types are most effective and cost-effective.

Homeless patients' perceptions about using cell phones to manage medications and attend appointments

OBJECTIVES

The objectives of this study were to (1) describe homeless persons' access and use of cell phones and their perceptions about using cell phone alerts to help manage medications and attend health care appointments and (2) identify demographic characteristics, medication use and appointment history and perceptions associated with interest in receiving cell phone alerts to manage medications and appointments.

METHODS

A cross-sectional survey was conducted in 2013 at a homeless clinic in Virginia. The questionnaire comprised items about cell phone usage, ownership and functions such as text messaging. Participants reported medication use and appointment history, perceptions about cell phone alerts and interest in receiving alerts to manage medications and appointments. Descriptive statistics for all variables are reported. Logistic regression was used to examine predictors of interest in using a cell phone to manage medications and appointments.

KEY FINDINGS

A total of 290 participants completed the survey; 89% had a cell phone. Seventy-seven percent were interested in appointment reminders, whereas 66%, 60% and 54% were interested in refill reminders, medication taking reminders and medication information messages respectively. Those who believed reminders were helpful were more likely to be interested in medication taking, refill and appointment reminder messages compared to those who did not believe reminders were helpful. A history of running out of medicine and forgetting appointments were predictors of interest in refill and appointment reminders.

CONCLUSIONS

Mobile technology is a feasible method for communicating medication and appointment information to those experiencing or at risk for homelessness.

The Use of Phone Technology in Outpatient Populations: A Systematic Review

Objective:

A systematic review was conducted to identify the types of phone technology used in the adult outpatient population with a focus on Hispanic patients and psychiatric populations.

Methods:

A search for articles was conducted on the EMBASE, PubMed and PsycINFO databases. Articles reviewed were peer-reviewed, full-text, English language and published through mid-November 2014.

Results:

Twenty-one articles were included in this review and grouped according to combinations of phone technology, medical specialty area and population. For all articles, phone technology was defined as telephone, cell, or smart phone. Technology was used in psychiatry with Hispanic population in four articles, in psychiatry with non-Hispanic population in seven articles and in other specialties with Hispanic population in ten articles. Articles were evaluated for quality. Six articles were assessed as strong, eight were moderate and seven were weak in global quality. Interventions included direct communication, text messaging, interactive voice response, camera and smart phone app. Studies with Hispanic populations used more text messaging, while studies in psychiatry favored direct communication. The majority of articles in all groups yielded improvements in health outcomes.

Conclusion:

Few studies have been conducted using phone technology in Hispanic and psychiatric populations. Various phone technologies can be helpful to patients in diverse populations and have demonstrated success in improving a variety of specific and overall healthcare outcomes. Phone technologies are easily adapted to numerous settings and populations and are valuable tools in efforts to increase access to care.

Retaining homeless veterans in outpatient care: a pilot study of mobile phone text message appointment reminders

OBJECTIVES

We examined the feasibility of using mobile phone text messaging with homeless veterans to increase their engagement in care and reduce appointment no-shows.

METHODS

We sent 2 text message reminders to participants (n = 20) before each of their outpatient appointments at an urban Veterans Affairs medical center. Evaluation included pre- and postsurvey questionnaires, open-ended questions, and review of medical records. We estimated costs and savings of large-scale implementation.

RESULTS

Participants were satisfied with the text-messaging intervention, had very few technical difficulties, and were interested in continuing. Patient-cancelled visits and no-shows trended downward from 53 to 37 and from 31 to 25, respectively. Participants also experienced a statistically significant reduction in emergency department visits, from 15 to 5 (difference of 10; 95% confidence interval [CI]  = 2.2, 17.8; P = .01), and a borderline significant reduction in hospitalizations, from 3 to 0 (difference of 3; 95% CI = -0.4, 6.4; P = .08).

CONCLUSIONS

Text message reminders are a feasible means of reaching homeless veterans, and users consider it acceptable and useful. Implementation may reduce missed visits and emergency department use, and thus produce substantial cost savings.

Assessing health conditions and medication use among the homeless community in Long Beach, California

Objective:

Persons experiencing homelessness are a vulnerable population and are at increased risk for morbidity and all-cause mortality compared to the general population. This study sought to evaluate medication use, regular physician visits, and identify health conditions among the homeless population of Long Beach, California.

Methods:

Two “brown bag” medication review events were held at homeless shelters in the Long Beach area. Demographic information, medication use, and comorbid disease states were obtained through surveys.

Findings:

Three-fourths of the cohort (95 participants) consisted of males, and the average age of participants was 48 years. Psychiatric disorders and cardiovascular disease were the most common disease states reported at 32% and 46%, respectively and so were medications used in treating these chronic diseases. Medication adherence was found to be a significant problem in this population, where more than 30% of patients were nonadherent to medications for chronic diseases. Furthermore, foot problems, hearing and vision difficulties constitute the most commonly overlooked health problems within the homeless population.

Conclusion:

Based on this and other similar finding, we must accept that the homeless represent a vulnerable population, and that because of this fact, more programs should be focused at improving availability and access to health care among the homeless. Regarding the high number of reported health problems in the study, more studies are needed and more studies should incorporate screening for foot, hearing, and vision issues, both to increase awareness and to provide an opportunity for devising possible solutions to these highly preventable conditions.

A Spanish pillbox app for elderly patients taking multiple medications: randomized controlled trial

Background

Nonadherence and medication errors are common among patients with complex drug regimens. Apps for smartphones and tablets are effective for improving adherence, but they have not been tested in elderly patients with complex chronic conditions and who typically have less experience with this type of technology.

Objective

The objective of this study was to design, implement, and evaluate a medication self-management app (called ALICE) for elderly patients taking multiple medications with the intention of improving adherence and safe medication use.

Methods

A single-blind randomized controlled trial was conducted with a control and an experimental group (N=99) in Spain in 2013. The characteristics of ALICE were specified based on the suggestions of 3 nominal groups with a total of 23 patients and a focus group with 7 professionals. ALICE was designed for Android and iOS to allow for the personalization of prescriptions and medical advice, showing images of each of the medications (the packaging and the medication itself) together with alerts and multiple reminders for each alert. The randomly assigned patients in the control group received oral and written information on the safe use of their medications and the patients in the experimental group used ALICE for 3 months. Pre and post measures included rate of missed doses and medication errors reported by patients, scores from the 4-item Morisky Medication Adherence Scale (MMAS-4), level of independence, self-perceived health status, and biochemical test results. In the experimental group, data were collected on their previous experience with information and communication technologies, their rating of ALICE, and their perception of the level of independence they had achieved. The intergroup intervention effects were calculated by univariate linear models and ANOVA, with the pre to post intervention differences as the dependent variables.

Results

Data were obtained from 99 patients (48 and 51 in the control and experimental groups, respectively). Patients in the experimental group obtained better MMAS-4 scores (P<.001) and reported fewer missed doses of medication (P=.02). ALICE only helped to significantly reduce medication errors in patients with an initially higher rate of errors (P<.001). Patients with no experience with information and communication technologies reported better adherence (P<.001), fewer missed doses (P<.001), and fewer medication errors (P=.02). The mean satisfaction score for ALICE was 8.5 out of 10. In all, 45 of 51 patients (88%) felt that ALICE improved their independence in managing their medications.

Conclusions

The ALICE app improves adherence, helps reduce rates of forgetting and of medication errors, and increases perceived independence in managing medication. Elderly patients with no previous experience with information and communication technologies are capable of effectively using an app designed to help them take their medicine more safely.

New media use by patients who are homeless: the potential of mHealth to build connectivity

Background

Patients experiencing homelessness represent a disproportionate share of emergency department (ED) visits due to poor access to primary care and high levels of unmet health care needs. This is in part due to the difficulty of communicating and following up with patients who are experiencing homelessness.

Objective

To determine the prevalence and types of “new media” use among ED patients who experience homelessness.

Methods

This was a cross-sectional observational study with sequential enrolling of patients from three emergency departments 24/7 for 6 weeks. In total, 5788 ED patients were enrolled, of whom 249 experienced homelessness. Analyses included descriptive statistics, and unadjusted and adjusted odds ratios.

Results

70.7% (176/249) of patients experiencing homelessness own cell phones compared to 85.90% (4758/5539) of patients in stable housing (P=.001) with the former more likely to own Androids, 70% (53/76) versus 43.89% (1064/2424), and the latter more likely to have iPhones, 44.55% (1080/2424) versus 17% (13/76) (P=.001). There is no significant difference in new media use, modality, or frequency for both groups; however, there is a difference in contract plan with 50.02% (2380/4758) of stably housed patients having unlimited minutes versus 37.5% (66/176) of homeless patients. 19.78% (941/4758) of patients in stable housing have pay-as-you-go plans versus 33.0% (58/176) of homeless patients (P=.001). Patients experiencing homelessness are more likely to want health information on alcohol/substance abuse, mental health, domestic violence, pregnancy and smoking cessation.

Conclusions

This study is unique in its characterization of new media ownership and use among ED patients experiencing homelessness. New media is a powerful tool to connect patients experiencing homelessness to health care.
