Abstract
Background: Medication adherence is widely recognized as an essential component of chronic disease management, yet only 50% of patients take their medication as prescribed. Newer technologies have the potential to improve medication adherence. Objective: To conduct a pilot study estimating the impact of a pharmacy-dispensed electronic reminder cap (SMARxT cap), which also records cap openings, on medication adherence and blood pressure (BP). Methods: After a 30-day run-in period, 28 individuals were randomized to receive a SMARxT or placebo cap on each BP medication. The primary outcome was adherence measured via (1) the medication possession ratio, (2) number of cap openings, and (3) self-report. The secondary outcome was the average of 2 BP readings at 6 months. Mean changes from baseline to 6 months were compared between the 2 groups. Results: The medication possession ratio increased 2.7% in the SMARxT cap group and decreased 1.1% in the control group (P = .13), and cap openings increased 11.9% in the SMARxT cap group and 9.9% in the control group (P = .83). Self-reported adherence increased 1.1 points in the SMARxT cap group and 0.8 points in the control group (P = .64). Systolic BP decreased 8.2 mm Hg in the SMARxT cap group and 2.8 mm Hg in the placebo cap group (P = .35), and diastolic BP decreased to 6.2 mm Hg in the SMARxT cap group and was unchanged in the placebo cap group (P = .06). Conclusions: Use of SMARxT cap showed nonsignificant improvement in medication adherence and BP lowering. This technology has potential to characterize and improve medication-taking behavior.

Rationale and Methods of Evaluation for ACHO, A New Virtual Assistant to Improve Therapeutic Adherence in Rural Elderly Populations: A User-Driven Living Lab. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18157904.

Abstract
Low therapeutic adherence is a concern for health professionals as it decreases therapeutic efficiency while increasing costs, especially in elderly populations. To increase therapeutic adherence in elderly populations, the technology applied in the medical devices that are used must be adapted to improve usability. This paper outlines the rationale behind, and methods applied to assess the usability of, ACHO (Assistant on Care and Health Offline), a voice assistant that provides elderly patients with reminders of medical appointments to attend and when they need to take their medication. This work is a descriptive, cross-sectional, observational study, and will include a three-phase (analysis, testing and refinement) multidimensional usability analysis of an initial prototype, in the setting of a user-driven Living Lab, which enables the needs and characteristics of the end users to be identified and incorporated into the prototype with each iteration, in which a multidisciplinary team of researchers and users will participate as co-creators. This methodology will allow us to develop a better prototype, increasing usability and, thus, increasing therapeutic adherence.

Treatment Adherence in Chronic Conditions during Ageing: Uses, Functionalities, and Cultural Adaptation of the Assistant on Care and Health Offline (ACHO) in Rural Areas. J Pers Med 2021; 11:173. [PMID: 33801439 PMCID: PMC7999645 DOI: 10.3390/jpm11030173] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 02/23/2021] [Accepted: 02/25/2021] [Indexed: 12/16/2022] Open
Abstract
The increasingly common scenario of an ageing population is related to a rise in the prevalence of problems associated with chronic conditions and comorbidities. Polypharmacy is frequent among this population, and it is a situation that can create medication management and adherence issues. This article introduces the features and functionalities of a voice assistant (Assistant on Health and Care Offline, ACHO) that aims to facilitate treatment adherence among elderly adults. Specifically adapted for its use in rural contexts, it does not require an Internet connection. Its development consisted of two stages: a first stage of problem diagnosis, in which the classic tools of ethnographic fieldwork were used, and a second stage of design implementing methodologies developed by Ambient Assisted Living (AAL) programmes. The main design characteristic of this new digital care system is that it is adapted to the needs of its end-users. It includes features such as voice customisation and the personal identification of medication, it can be connected to other digital devices, and information is introduced and supervised by healthcare professionals. These custom features introduce a safer medication administration procedure, improve supervision strategies, and increase patients' trust in the prescription process.

Abstract
BACKGROUND This position paper highlights the opportunistic integral role of the pharmacist across the patient pathway utilizing cardiovascular care as an example. The paper aims to highlight the potential roles that pharmacists worldwide can have (or already have) to provide efficient patient care in the context of interprofessional collaboration. METHODS It results from a literature review and experts seeking advice to identify existing interventions and potential innovative interventions. We developed a conceptual framework highlighting seven critical phases in the patient pathway and for each of those listed some of the initiatives identified by our experts worldwide. RESULTS Existing pharmacists' interventions in each of these phases have been identified globally. Various examples in the area of prevention and self-management were found to exist for long; the contribution for early detection and subsequently to timely diagnosis were also quite clear; integration of care was perhaps one of the areas needing greater development, although interventions in secondary care were also quite common. Tertiary care and end of life interventions were found to often be left for other healthcare professionals. CONCLUSION On the basis of the findings, we can argue that much has been done but globally consider that pharmacists are still an untapped resource potentially useful for improved patient care.

Abstract
OBJECTIVE We evaluated whether regular mobile phone text reminders improved patients' retention in antiretroviral therapy (ART) care in Mozambique. DESIGN SMSaúde was a randomized control trial of HIV-infected patients on ART who received regular text message reminder vs. standard of care at 3 public health facilities in Maputo Province, Mozambique. The primary outcome was retention in HIV care. Between November 2011 and March 2012, 830 eligible HIV-infected patients on ART were randomized 1:1 to the text reminder intervention or standard of care. METHODS We used Kaplan-Meier estimators and log-rank tests to compare proportions of patients who received SMS reminders who were retained in HIV care compared to the control group who received standard of care. Post hoc analyses were performed using Cox proportional hazards models stratified by urban/rural facility and when initiated ART (≤3 months vs. >3 months). Hazard ratios and confidence intervals (CIs) are reported. Analysis was with intention to treat. RESULTS Patients who received text messages had lower attrition from HIV care at 12 months, though the difference was nonsignificant (RR: 0.68, 95% CI: 0.41 to 1.13). Among urban patients, text messages improved retention in HIV care (RR: 0.54, 95% CI: 0.31 to 0.95). Intervention patients newly initiated on ART (<3 months) had lower attrition than control patients (HR: 0.54; 95% CI: 0.23 to 0.91), especially urban newly initiated patients (HR: 0.20, 95% CI: 0.06 to 0.64). Text messages had no effect on retention among rural patients. CONCLUSIONS Text messages did not improve retention in HIV care for all patients on ART but improved retention in care of urban patients and those who recently started ART and received text reminders compared with standard of care.

Abstract
BACKGROUND Portugal is currently facing a serious economic and financial crisis, which is dictating some important changes in the health care sector. Some of these measures may potentially influence patients' access to medication and consequently adherence, which will ultimately impact on health status, especially in chronic patients. AIMS This study aimed at providing a snapshot of adherence in patients with chronic conditions in Portugal between March and April 2012. SETTING Community pharmacy in Portugal. METHOD A cross-sectional pilot study was undertaken, where patients were recruited via community pharmacies to a questionnaire study evaluating the number of prescribed and purchased drugs and, when these figures were inconsistent, the reasons for this. MAIN OUTCOME MEASURES Primary and secondary adherence measures. Failing to purchase prescription items was categorized as primary nonadherence. Secondary nonadherence was attributed to purchasing prescription items, but not taking medicines as prescribed. RESULTS Data were collected from 375 patients. Primary nonadherence was identified in 22.8 % of patients. Regardless of the underlying condition, the most commonly reported reason for primary non-adherence was having spare medicines at home ("leftovers"), followed by financial problems. The latter appeared to be related to the class of medicines prescribed. Primary non-adherence was associated with low income (<475 <euro>/month; p = 0.026). Secondary non-adherence, assessed by the 7-MMAS was detected in over 50 % of all patients, where unintentional nonadherence was higher than intentional nonadherence across all disease conditions. CONCLUSION This study revealed that more than one fifth of chronic medication users report primary nonadherence (22.8 %) and more than 50 % report secondary nonadherence. Data indicates that the existence of spare medicines and financial constraints occurred were the two most frequent reasons cited for nonadherence (47, 6-64, 8 and 19-45.5 %, depending on the major underlying condition, respectively).

Abstract
BACKGROUND People who are prescribed self administered medications typically take only about half their prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications. OBJECTIVES The primary objective of this review is to assess the effects of interventions intended to enhance patient adherence to prescribed medications for medical conditions, on both medication adherence and clinical outcomes. SEARCH METHODS We updated searches of The Cochrane Library, including CENTRAL (via http://onlinelibrary.wiley.com/cochranelibrary/search/), MEDLINE, EMBASE, PsycINFO (all via Ovid), CINAHL (via EBSCO), and Sociological Abstracts (via ProQuest) on 11 January 2013 with no language restriction. We also reviewed bibliographies in articles on patient adherence, and contacted authors of relevant original and review articles. SELECTION CRITERIA We included unconfounded RCTs of interventions to improve adherence with prescribed medications, measuring both medication adherence and clinical outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive findings at earlier time points. DATA COLLECTION AND ANALYSIS Two review authors independently extracted all data and a third author resolved disagreements. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Pooling results according to one of these characteristics still leaves highly heterogeneous groups, and we could not justify meta-analysis. Instead, we conducted a qualitative analysis with a focus on the RCTs with the lowest risk of bias for study design and the primary clinical outcome. MAIN RESULTS The present update included 109 new RCTs published since the previous update in January 2007, bringing the total number of RCTs to 182; we found five RCTs from the previous update to be ineligible and excluded them. Studies were heterogeneous for patients, medical problems, treatment regimens, adherence interventions, and adherence and clinical outcome measurements, and most had high risk of bias. The main changes in comparison with the previous update include that we now: 1) report a lack of convincing evidence also specifically among the studies with the lowest risk of bias; 2) do not try to classify studies according to intervention type any more, due to the large heterogeneity; 3) make our database available for collaboration on sub-analyses, in acknowledgement of the need to make collective advancement in this difficult field of research. Of all 182 RCTs, 17 had the lowest risk of bias for study design features and their primary clinical outcome, 11 from the present update and six from the previous update. The RCTs at lowest risk of bias generally involved complex interventions with multiple components, trying to overcome barriers to adherence by means of tailored ongoing support from allied health professionals such as pharmacists, who often delivered intense education, counseling (including motivational interviewing or cognitive behavioral therapy by professionals) or daily treatment support (or both), and sometimes additional support from family or peers. Only five of these RCTs reported improvements in both adherence and clinical outcomes, and no common intervention characteristics were apparent. Even the most effective interventions did not lead to large improvements in adherence or clinical outcomes. AUTHORS' CONCLUSIONS Across the body of evidence, effects were inconsistent from study to study, and only a minority of lowest risk of bias RCTs improved both adherence and clinical outcomes. Current methods of improving medication adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. The research in this field needs advances, including improved design of feasible long-term interventions, objective adherence measures, and sufficient study power to detect improvements in patient-important clinical outcomes. By making our comprehensive database available for sharing we hope to contribute to achieving these advances.

Abstract
OBJECTIVES To systematically review the evidence on the impact of interventions to improve medication adherence in adults prescribed antihypertensive medications. METHODS An electronic search was undertaken of articles published between 1979 and 2009, without language restriction, that focused on interventions to improve antihypertensive medication adherence among patients (≥18 years) with essential hypertension. Studies must have measured adherence as an outcome of the intervention. We followed standard guidelines for the conduct and reporting of the review and conducted a narrative synthesis of reported data. RESULTS Ninety-seven articles were identified for inclusion; 35 (35 of 97, 36.1%) examined interventions to directly improve medication adherence, and the majority (58 of 97, 59.8%) were randomized controlled trials. Thirty-four (34 of 97, 35.1%) studies reported a statistically significant improvement in medication adherence. DISCUSSION/CONCLUSIONS Interventions aimed at improving patients' knowledge of medications possess the greatest potential clinical value in improving adherence with antihypertensive therapy. However, we identified several limitations of these studies, and advise future researchers to focus on using validated adherence measures, well-designed randomized controlled trials with relevant adherence and clinical outcomes, and guidelines on the appropriate design and analysis of adherence research.

Abstract
BACKGROUND Many patients experience difficulties in adhering to long-term treatment. Although patients' reasons for not being adherent are diverse, one of the most commonly reported barriers is forgetfulness. Reminding patients to take their medication may provide a solution. Electronic reminders (automatically sent reminders without personal contact between the healthcare provider and patient) are now increasingly being used in the effort to improve adherence. OBJECTIVE To examine the effectiveness of interventions using electronic reminders in improving patients' adherence to chronic medication. METHODS A comprehensive literature search was conducted in PubMed, Embase, PsycINFO, CINAHL and Cochrane Central Register of Controlled Trials. Electronic searches were supplemented by manual searching of reference lists and reviews. Two reviewers independently screened all citations. Full text was obtained from selected citations and screened for final inclusion. The methodological quality of studies was assessed. RESULTS Thirteen studies met the inclusion criteria. Four studies evaluated short message service (SMS) reminders, seven audiovisual reminders from electronic reminder devices (ERD), and two pager messages. Best evidence synthesis revealed evidence for the effectiveness of electronic reminders, provided by eight (four high, four low quality) studies showing significant effects on patients' adherence, seven of which measured short-term effects (follow-up period <6 months). Improved adherence was found in all but one study using SMS reminders, four studies using ERD and one pager intervention. In addition, one high quality study using an ERD found subgroup effects. CONCLUSION This review provides evidence for the short-term effectiveness of electronic reminders, especially SMS reminders. However, long-term effects remain unclear.

Abstract
BACKGROUND People who are prescribed self-administered medications typically take less than half the prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications, but also might increase their adverse effects. OBJECTIVES To update a review summarizing the results of randomized controlled trials (RCTs) of interventions to help patients follow prescriptions for medications for medical problems, including mental disorders but not addictions. SEARCH STRATEGY We updated searches of The Cochrane Library, MEDLINE, CINAHL, EMBASE, International Pharmaceutical Abstracts (IPA), PsycINFO (all via OVID) and Sociological Abstracts (via CSA) in January 2007 with no language restriction. We also reviewed bibliographies in articles on patient adherence and articles in our personal collections, and contacted authors of relevant original and review articles. SELECTION CRITERIA Articles were selected if they reported an unconfounded RCT of an intervention to improve adherence with prescribed medications, measuring both medication adherence and treatment outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive initial findings. DATA COLLECTION AND ANALYSIS Study design features, interventions and controls, and results were extracted by one review author and confirmed by at least one other review author. We extracted adherence rates and their measures of variance for all methods of measuring adherence in each study, and all outcome rates and their measures of variance for each study group, as well as levels of statistical significance for differences between study groups, consulting authors and verifying or correcting analyses as needed. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Therefore, we did not feel that quantitative analysis was scientifically justified; rather, we conducted a qualitative analysis. MAIN RESULTS For short-term treatments, four of ten interventions reported in nine RCTs showed an effect on both adherence and at least one clinical outcome, while one intervention reported in one RCT significantly improved patient adherence, but did not enhance the clinical outcome. For long-term treatments, 36 of 81 interventions reported in 69 RCTs were associated with improvements in adherence, but only 25 interventions led to improvement in at least one treatment outcome. Almost all of the interventions that were effective for long-term care were complex, including combinations of more convenient care, information, reminders, self-monitoring, reinforcement, counseling, family therapy, psychological therapy, crisis intervention, manual telephone follow-up, and supportive care. Even the most effective interventions did not lead to large improvements in adherence and treatment outcomes. AUTHORS' CONCLUSIONS For short-term treatments several quite simple interventions increased adherence and improved patient outcomes, but the effects were inconsistent from study to study with less than half of studies showing benefits. Current methods of improving adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. High priority should be given to fundamental and applied research concerning innovations to assist patients to follow medication prescriptions for long-term medical disorders.
