Patient Knowledge, Medication Adherence, and Influencing Factors: A Cross-Sectional Study among Hypertensive Patients in Greece. Healthcare (Basel) 2024; 12:916. [PMID: 38727473 PMCID: PMC11083400 DOI: 10.3390/healthcare12090916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 03/31/2024] [Accepted: 04/27/2024] [Indexed: 05/13/2024] Open
Abstract
This study aimed to investigate the knowledge of patients with hypertension about their condition, adherence to antihypertensive medication, and the factors influencing it. A cross-sectional study was conducted in two cardiology outpatient clinics of two tertiary hospitals, in Greece. The study included 188 patients diagnosed with hypertension. The patients' knowledge about their disease and adherence to medication were assessed by using the HK-LS and A-14 scales, respectively. Patients had sufficient knowledge levels about their disease, but significantly low levels of adherence to medication. Patients with higher knowledge levels were more adherent to medications [r(188) = 0.885, p < 0.001]. By using multivariate analysis, higher age (p = 0.018), residence in a more populous area (p = 0.041), more years with the disease (p = 0.012), and a lower number of medications (p = 0.03) were associated with higher levels of knowledge. Conversely, younger age (p = 0.036), lower educational levels (p = 0.048), fewer years with the disease (p = 0.001), and a higher number of medications (p = 0.003) were associated with lower adherence to medication. The Greek patients' hypertension knowledge was sufficient; however, adherence to medication was significantly low. Healthcare managers could utilize our findings to design targeted interventions for improving adherence to medication for these patients.

Reimagining Medication Adherence: A Novel Holistic Model for Hypertension Therapy. Patient Prefer Adherence 2024; 18:391-410. [PMID: 38370031 PMCID: PMC10870933 DOI: 10.2147/ppa.s442645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 01/14/2024] [Indexed: 02/20/2024] Open
Abstract
Purpose Patients' adherence to the prescribed therapy is influenced by several personal and social factors. However, existing studies have mostly focused on individual aspects. We took a holistic approach to develop a higher-level impact factor model. Patients and Methods In this independent, non-interventional, cross-sectional and anonymous study design the pharmacist recruited patients who entered the pharmacy and handed in a prescription for a blood pressure medication. The patients received a paper questionnaire with a stamped return envelope to volunteer participation. A total of 476 patients in Germany who reported having at least high normal blood pressure according to the Global Hypertension Practice Guidelines were surveyed. In this study, each patient received an average of 2.49 antihypertensive prescriptions and 7.9% of all patients received a fixed-dose combination. Partial least squares structural equation modeling was performed for model analytics since it enables robust analysis of complex relationships. Results Emotional attitude, behavioral control, and therapy satisfaction directly explained 65% of therapy adherence. The predictive power of the out-of-sample model for the Q2-statistic was significant. The patient's overall therapy satisfaction determined medication adherence. The medication scheme's complexity also influenced the adherence levels. Therapy satisfaction was significantly shaped by the complexity of the medication scheme, behavioral control, and emotional attitude. The results demonstrated the superior performance of fixed-dose combinations against combinations of mono-agents according to the adherence level. Additionally, patient-physician and patient-pharmacist relationships influenced behavioral control of medication therapy execution. According to the A14-scale to measure the level of adherence, 49.6% of patients were classified as adherent and the remainder as non-adherent. Conclusion The results enable healthcare stakeholders to target attractive variables for intervention to achieve maximum effectiveness. Moreover, the proven predictive power of the model framework enables clinicians to make predictions about the adherence levels of their hypertensive patients.

Quality of measurement properties of medication adherence instruments in cardiovascular diseases and type 2 diabetes mellitus: a systematic review and meta-analysis. Syst Rev 2023; 12:222. [PMID: 37993931 PMCID: PMC10664314 DOI: 10.1186/s13643-023-02340-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 08/29/2023] [Indexed: 11/24/2023] Open
Abstract
BACKGROUND Medication adherence has a major impact on reducing mortality and healthcare costs related to the treatment of cardiovascular diseases and diabetes mellitus. Selecting the best patient-reported outcome measure (PROM) among the many available for this kind of patient is extremely important. This study aims to critically assess, compare and synthesize the quality of the measurement properties of patient-reported outcome measures to assess medication adherence among patients with cardiovascular diseases and/or type 2 diabetes mellitus. METHODS This review followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The searches were performed in Web of Science, SCOPUS, PubMed, CINAHL, EMBASE, LILACS, PsycINFO, and ProQuest (gray literature). RESULTS A total of 110 records encompassing 27 different PROMs were included in the review. The included records were published between 1986 and 2023, most of which reported studies conducted in the United States and were published in English. None of the PROMs were classified in the category "a", thus being recommended for use due to the quality of its measurement properties. The PROMs that should not be recommended for use (category "c") are the MTA, GMAS, DMAS-7, MALMAS, ARMS-D, and 5-item questionnaire. The remaining PROMs, e.g., MMAS-8, SMAQ, MEDS, MNPS, ARMS-12, MGT, MTA-OA, MTA-Insulin, LMAS-14, MARS-5, A-14, ARMS-10, IADMAS, MAQ, MMAS-5, ProMAS, ARMS-7, 3-item questionnaire, AS, 12-item questionnaire, and Mascard were considered as having the potential to be recommended for use (category "b"). CONCLUSION None of the included PROMs met the criteria for being classified as trusted and recommended for use for patients with cardiovascular diseases and/or type 2 diabetes mellitus. However, 21 PROMs have the potential to be recommended for use, but further studies are needed to ensure their quality based on the COSMIN guideline for systematic reviews of PROMs. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42019129109.

The Development and Validation of the "Hippocratic Hypertension Self-Care Scale". Healthcare (Basel) 2023; 11:2579. [PMID: 37761775 PMCID: PMC10530843 DOI: 10.3390/healthcare11182579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 09/08/2023] [Accepted: 09/16/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND The adoption of self-care behaviors among patients with arterial hypertension (AH) plays an important role in the management of their health condition. However, a lack of scales assessing self-care is observed. We aimed to develop and validate the Hippocratic hypertension self-care scale. METHODS From a pool of questions derived from a literature review, 18 items were included in the scale and reviewed by a committee of experts. Participants indicated the frequency at which they followed the self-behavior prescribed in each statement on a five-point Likert scale. Data were collected between April 2019 and December 2019. RESULTS A total of 202 consecutive adult patients with AH were enrolled in the study. The internal consistency of the scale was found to be 0.807, using Cronbach's alpha coefficient. An exploratory factor analysis identified two domains that accounted for 92.94% of the variance in the scale items; however, each sub-scale could not be used as an independent scale. Finally, the test-retest of the scale showed a significant strong correlation (r = 0.0095, p < 0.001). CONCLUSION This analysis indicates that the scale is reliable and valid for assessing self-care behaviors in patients with AH. It is suggested that health professionals use it in their clinical practice to improve the management of AH.

Improving glycemic control in patients with type 2 diabetes mellitus through a peer support instant messaging service intervention (DiabPeerS): study protocol for a randomized controlled trial. Trials 2022; 23:308. [PMID: 35422003 PMCID: PMC9009500 DOI: 10.1186/s13063-022-06202-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Accepted: 03/26/2022] [Indexed: 12/15/2022] Open
Abstract
Background Diabetes mellitus is one of the four priority non-communicable diseases worldwide. It can lead to serious long-term complications and produces significant costs. Due to the chronicle character of the disease, it requires continuous medical treatment and good therapy adherence of those suffering. Therefore, diabetes self-management education (DSME) (and support DSMES) plays a significant role to increase patient’s self-management capacity and improve diabetes therapy. Research indicates that these outcomes might be difficult to maintain. Consequently, effective strategies to preserve the positive effects of DSMES are needed. Preliminary results show that peer support, which means support from a person who has experiential knowledge of a specific behavior or stressor and similar characteristics as the target population, is associated with better outcomes in terms of HbA1c, cardiovascular disease risk factors or self-efficacy at a lower cost compared to standard therapy. Peer-supported instant messaging services (IMS) approaches have significant potential for diabetes management because support can be provided easily and prompt, is inexpensive, and needs less effort to attend compared to standard therapy. The major objective of the study is to analyze the impact of a peer-supported IMS intervention in addition to a standard diabetes therapy on the glycemic control of type 2 diabetic patients. Methods A total of 205 participants with type 2 diabetes mellitus will be included and randomly assigned to an intervention or control group. Both groups will receive standard therapy, but the intervention group will participate in the peer-supported IMS intervention, additionally. The duration of the intervention will last for 7 months, followed by a follow-up of 7 months. Biochemical, behavioral, and psychosocial parameters will be measured before, in the middle, and after the intervention as well as after the follow-up. Discussion Type 2 diabetes mellitus and other non-communicable diseases put healthcare systems worldwide to the test. Peer-supported IMS interventions in addition to standard therapy might be part of new and cost-effective approaches to support patients independent from time and place.

Development and validation of a questionnaire to determine medical orders non-adherence: a sequential exploratory mixed-method study. BMC Health Serv Res 2021; 21:136. [PMID: 33579267 PMCID: PMC7881677 DOI: 10.1186/s12913-021-06147-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Accepted: 02/02/2021] [Indexed: 11/13/2022] Open
Abstract
Background Patients’ non-adherence with medical orders of physicians in outpatient clinics can lead to reduced clinical effectiveness, inadequate treatment, and increased medical care expenses. This study was conducted to develop and validate a questionnaire to determine the reasons for patients’ non-adherence with physicians’ medical orders. Methods A sequential exploratory mixed-method study was conducted in two stages. The first stage comprised a qualitative stage to generate the primary items of the questionnaire. This stage provided findings of two sub-stages comprising a literature review and the findings of a qualitative conventional content analysis of 19 semi-structured interviews held with patients, physicians, and managers of the outpatient clinics in Kerman, an area located in southeastern Iran. The second stage comprised a quantitative study aiming evaluation of the instrument psychometric properties, including the face, content, construct, and reliability assessment of the questionnaire. Construct validity assessment was evaluated using exploratory factor analysis (EFA). The reliability assessment was done using assessing internal consistency (Cronbach’s alpha). To assess the construct validity of the questionnaire, four hundred and forty patients referred to outpatient clinics in Kerman were selected using stratified convenience sampling to fill out the questionnaire. The sample size was calculated using the Cochran formula. Qualitative and quantitative data were analyzed by MAXQDA 10 and Stata version 14, respectively. Results The primary items contained 57 items, of which 42 met the minimum acceptable value of 0.78 for item-level content validity index (I-CVI = 1 for 24 items and I-CVI = 0.8 for 18 items). Item-level content validity ratio (I-CVR) was confirmed for 18 items with a minimum acceptable value of 0.99 for five experts. Finally, 18 items obtained the acceptable value for both I-CVI and I-CVR indicators and were confirmed. Using EFA, four factors (intrapersonal-psychological, intrapersonal-cognitive, provider-related, and socio-economic reasons) with 18 items and Cronbach’s alpha coefficient of 0.70, 0.66, 0.73, and 0.71, respectively, were identified and explained 51% of the variance. The reliability of the questionnaire (r = 0.70) was confirmed. Conclusion The questionnaire with four dimensions is a valid and reliable instrument that can help determine the perceived reasons for non-adherence with medical orders in the outpatient services system. Supplementary Information The online version contains supplementary material available at 10.1186/s12913-021-06147-3.

Factors That Influence Adherence to Medication in Adults With Congenital Heart Disease (ACHD). Front Psychiatry 2021; 12:788013. [PMID: 34899440 PMCID: PMC8660073 DOI: 10.3389/fpsyt.2021.788013] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Accepted: 11/03/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: Innovative operative and interventional procedures have improved survival in congenital heart disease (CHD), and today more than 90% of these children reach adulthood. Consequently, adherence and psychosocial issues are becoming increasingly important because non-adherence to treatment recommendations worsens morbidity and mortality. This study aimed to identify factors modifying adherence to medication in adult congenital heart disease (ACHD). Methods: This cross-sectional study included 451 outpatients (female 47.9%, average age ± SD: 37.9 ± 12 years) from the ACHD department, who completed a questionnaire assessing medication non-adherence and individual barriers to treatment. Further assessments included psychological well-being (Hospital Anxiety and Depression scale; HADS), childhood traumatization, sociodemographic, and clinical data. Binary logistic regression analysis calculated the impact of these factors on drug adherence. Results: Of the 451 patients 162 participants (35.9%) reported to be non-adherent. In univariate analysis non-adherence to treatment was associated with smoking (P = < 0.001) and internet addiction (P = 0.005). Further factors negatively influencing adherence were the presence of depressive symptoms (P = 0.002), anxiety (P = 0.004), and childhood traumatization (p = 0.002). Factors positively associated with adherence were older age (P = 0.003) and more advanced heart disease as indicated by NYHA class (P = 0.01), elevated NT-proBNP (P = 0.02), device therapy (P = 0.002) and intermittent arrhythmias (P = 0.01). In multivariate analysis especially psychopathological factors such as depression (P = 0.009), anxiety (P = 0.032) and childhood traumatization (P = 0.006) predicted non-adherence. Conclusion: Adherence is a critical issue in the long-term management of ACHD. Identifying modifiable factors that worsen adherence offers the opportunity for targeted interventions. Depressive symptoms, anxiety, and adverse childhood experiences are amenable to psychosocial interventions, as well as cigarette smoking. Our study suggests that a multimodal and interdisciplinary treatment concept for the long-term management of adults with congenital heart disease could be beneficial. Whether it will further improve morbidity and mortality, should be assessed in prospective interventions.

Abstract
OBJECTIVE To create a mobile application able to help patients follow medical treatments properly. METHODS We designed and developed a custom Android/iOS App to remind patients of the pharmaceutical drugs to be taken, of the visits and exams to attend, and to detect their compliance with their personal therapeutic plan. In this paper we describe the App development, UX/UI design, Gamification. TuTOR is an Android and iOS application designed to remind patients of the drugs to be taken, giving them all the information related to their therapeutic plans in a simple and non-invasive way. Thanks to a dedicated back-office, specially designed to meet specific medical information needs, the App can also help physicians detect their patients' compliance with their treatments and modify prescriptions in real time. The App also ensures a state-of-the-art approach to data security and privacy protection. The main feature of TuTOR is the smart therapy assistant, which features dedicated alarms to remind users of taking their prescription drugs. Thanks to the automatic synchronization with a local database, the alert system works even without connection to the Internet. Particular attention was paid during the App's design process: we looked to create an intuitive interface to ensure absolute ease of use, with state-of-the-art visual design aimed at maximizing user experience. Other relevant features include the App's ability to givevisual evidence of the most important drugs to be taken and its note-taking feature, which gives patients the possibility to note down indications on why a specific drug was skipped. The App also keeps track of upcoming medical exams, laboratory tests, and visits on a devoted calendar. It also helps patients by listing therapy contacts, such as physicians' phone numbers, and indicates all medical references by showing, for example, locations of relevant clinics and pharmacies on a map. Thanks to specific visual progress indicators and an innovative gamification approach, the App encourages users to faithfully follow therapy guidelines. With TuTOR, assessing the therapy's state of completion is quick and easy.Thanksto the privacy-by-design approach used, all data managed by the system is compliant with the European Privacy Regulation and it is not available to third parties. EXPECTED RESULTS A mobile App for medication adherence might increase objectively and subjectively measured adherence.

Abstract
BACKGROUND the choice of the appropriate tool for assessing level of medication adherence is a significant barrier in scientific research. AIMS to translate into Greek and test the reliability of the Hill-Bone and A-14 scales among patients with hypertension. Also, to compare patients' responses in the Hill-Bone scale, A-14 scale and Morisky Medication Adherence Scale (MMAS). METHODS data collection occurred between February 2016 and March 2016 at a general hospital in Athens, Greece. The sample consisted of hypertensive patients (n=34) and non-hypertensive patients (n=34). FINDINGS the coefficient alpha in hypertensive patients was 0.76 for Hill-Bone, 0.64 for MMAS and 0.91 for the A-14 scale. In non-hypertensive patients, the Cronbach's alpha for MMAS was 0.81 and 0.78 for A-14. A statistically significant difference was found among the mean scores of the scales, whereas strong correlation was found only between two pairs of questions with similar meaning. CONCLUSION all tools are appropriate to assess the level of medication adherence in Greek hypertensive patients. However, careful translation of the scales is essential since items with the same meaning could be understudied in a different way.

Self-blood pressure monitoring is associated with improved awareness, adherence, and attainment of target blood pressure goals: Prospective observational study of 7751 patients. J Clin Hypertens (Greenwich) 2019; 21:1298-1304. [PMID: 31393062 DOI: 10.1111/jch.13647] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Revised: 05/12/2019] [Accepted: 05/27/2019] [Indexed: 01/10/2023]
Abstract
We investigated whether self-blood pressure monitoring (SBPM) can improve the control rate of blood pressure (BP), adherence of antihypertensive medications, and the awareness of the importance of BP control in hypertensive patients. A total of 7751 patients who visited the outpatient clinics of private and university hospitals in Korea were given automatic electronic BP monitors and were recommended to measure their BP daily at home for 3 months. Changes in office BP, attainment of target BP, adherence to taking antihypertensive drugs, and awareness of BP were compared before and after SBPM. Patients and physicians were surveyed on their perception of BP and SBPM. Mean BP significantly decreased from 142/88 to 129/80 mm Hg (P < .001), and attainment of the target BP increased from 32% to 59% (P < .001) after SBPM. Drug non-adherence, which was defined as patient's not taking medication days per week, decreased significantly from 0.86 days to 0.53 days (P < .001). The rate of awareness of the BP goal increased from 57% to 81% (P < .001). Patients estimated that their mean BP was 125/81 mm Hg, but their actual mean BP was 142/88 mm Hg. Awareness about the importance of SBPM increased from 90% to 98%. The rate of SBPM ≥ once per week further increased, from 34% to 96%. In conclusion, SBPM is associated with reduced BP, better BP control rate, greater drug adherence, and improved perception of BP by the patients.

Abstract
To assess the adherence level of antihypertensive treatment and identify any associated risk factors in a sample of hypertensive patients from China.A cross-sectional study involving 488 Chinese hypertensive patients was conducted in a tertiary hospital in Xi'an, China. Data were collected regarding socio-demographic factors and hypertension-related clinical characteristics. The adherence to treatment was assessed using the previously validated instrument: therapeutic adherence scale for hypertensive patients.A total of 27.46% of patients were compliant with their antihypertensive treatments. Three factors were identified to be independently associated with antihypertensive treatment adherence: gender (P = .034), residence (P = .029), duration of high blood pressure (P < .001). Gender, residence, occupation, and the duration of antihypertensive drugs treatment used were found to have significant effects on treatment adherence in certain categories.Treatment adherence among hypertensive patients in China was poor. More attention and effective strategies should be designed to address factors affecting treatment adherence. Education about hypertension knowledge should be strengthened for patients. Moreover, the importance of lifestyle modification during hypertension treatment is often neglected by patients, therefore, there is an urgent need to educate hypertensive patients about the adherence to lifestyle modifications.

Abstract
Background: Non-adherence to direct oral anticoagulants (DOACs) remains a matter of concern, especially for patients with a recent stroke. However, data on electronically monitored adherence and adherence-improving interventions are scarce. Aims: We aim to use electronic monitoring in DOAC-treated stroke patients to (i) evaluate the effect of an educational, reminder-based adherence-improving intervention, (ii) investigate predictors of non-adherence, (iii) identify reliable self-report measures of adherence, and (iv) explore the association of non-adherence with clinical outcomes. Methods: Single-center, randomized, crossover, open-label study. Adherence to DOACs of polymedicated patients self-administering their medication will be monitored electronically throughout the 12-month-long study following hospitalization for ischemic stroke. After a 6-month observational phase, patients will receive pharmaceutical counseling with feedback on their intake history and be given a multi-compartment pillbox for the subsequent 6-month interventional phase. The pillbox will provide intake reminders either during the first or the last three interventional-phase months. Patients will be randomly allocated to reminders-first or reminders-last. Study outcomes: Primary: non-optimal timing adherence; Secondary: non-optimal taking adherence; timing adherence; taking adherence; self-reported adherence; clinical outcomes including ischemic and hemorrhagic events; patient-reported device usability and satisfaction. Sample size estimates: A sample of 130 patients provides 90% power to show a 20% improvement of the primary adherence outcome with intake reminders. Discussion: MAAESTRO will investigate various aspects of non-adherence and evaluate the effect of an adherence-improving intervention in DOAC-treated patients with a recent stroke using electronic monitoring.

Abstract
Medication adherence is crucial for success in the management of patients with chronic conditions. This study analyzes whether a mobile application on a tablet aimed at supporting drug intake and vital sign parameter documentation affects adherence in elderly patients.Patients with coronary heart disease and no prior knowledge of tablet computers were recruited. They received a personal introduction to the mobile application Medication Plan, installed on an Apple iPad. The study was conducted using a crossover design with 3 sequences: initial phase, interventional phase (28 days of using the app system), and comparative phase (28 days of using a paper diary). Users experienced the interventional and comparative phases alternately.A total of 24 patients (12 males; mean age 73.8 years) were enrolled in the study. The mean for subjectively assessed adherence (A14-scale; 5-point Likert scale, from "never" to "very often" which results in a score from 0 to 56) before the study was 50.0 (SD = 3.44). After both interventions there was a significant increase, which was more pronounced after the interventional phase (54.0; SD = 2.01) than after the comparative phase (52.6; SD = 2.49) (for all pairs after both interventions, P <0.001). Neither medical conditions nor the number of drug intake (amount and frequency of drug taking) per day affected subjective adherence. Logging data showed a significantly stronger adherence for the medication app than the paper system for both blood pressure recordings (P <0.001) and medication intake (P = 0.033). The majority of participants (n = 22) stated that they would like to use the medication app in their daily lives and would not need further assistance with the app.A mobile app for medication adherence increased objectively and subjectively measured adherence in elderly users undergoing rehabilitation. The findings have promising clinical implications: digital tools can assist chronic disease patients achieve adherence to medication and to blood pressure measurement. Although this requires initial offline training, it can reduce complications and clinical overload because of nonadherence.

Abstract
OBJECTIVE To improve medication appropriateness and adherence in elderly patients with multimorbidity, we developed a complex intervention involving general practitioners (GPs) and their healthcare assistants (HCA). In accordance with the Medical Research Council guidance on developing and evaluating complex interventions, we prepared for the main study by testing the feasibility of the intervention and study design in a cluster randomised pilot study. SETTING 20 general practices in Hesse, Germany. PARTICIPANTS 100 cognitively intact patients ≥65 years with ≥3 chronic conditions, ≥5 chronic prescriptions and capable of participating in telephone interviews; 94 patients completed the study. INTERVENTION The HCA conducted a checklist-based interview with patients on medication-related problems and reconciled their medications. Assisted by a computerised decision-support system (CDSS), the GPs discussed medication intake with patients and adjusted their medication regimens. The control group continued with usual care. OUTCOME MEASURES Feasibility of the intervention and required time were assessed for GPs, HCAs and patients using mixed methods (questionnaires, interviews and case vignettes after completion of the study). The feasibility of the study was assessed concerning success of achieving recruitment targets, balancing cluster sizes and minimising drop-out rates. Exploratory outcomes included the medication appropriateness index (MAI), quality of life, functional status and adherence-related measures. MAI was evaluated blinded to group assignment, and intra-rater/inter-rater reliability was assessed for a subsample of prescriptions. RESULTS 10 practices were randomised and analysed per group. GPs/HCAs were satisfied with the interventions despite the time required (35/45 min/patient). In case vignettes, GPs/HCAs needed help using the CDSS. The study made no patients feel uneasy. Intra-rater/inter-rater reliability for MAI was excellent. Inclusion criteria were challenging and potentially inadequate, and should therefore be adjusted. Outcome measures on pain, functionality and self-reported adherence were unfeasible due to frequent missing values, an incorrect manual or potentially invalid results. CONCLUSIONS Intervention and trial design were feasible. The pilot study revealed important limitations that influenced the design and conduct of the main study, thus highlighting the value of piloting complex interventions. TRIAL REGISTRATION NUMBER ISRCTN99691973; Results.

Abstract
RATIONALE, AIMS AND OBJECTIVES To translate in German the 8-item Morisky Medication Adherence Scale (MMAS-8D). To validate it against objective and subjective measures of adherence in cardiovascular patients with polypharmacy. METHODS A standard forward-backward procedure was used to translate the MMAS-8 into German. Validation took place on a convenience sample of ambulatory patients on chronic antiplatelet therapy between June 2010 and June 2011. Objective adherence was obtained from electronically monitored multi-drug punch cards. Internal consistency was assessed using Cronbach's alpha coefficient, construct validity using exploratory factor analyses and correlations between MMAS-8D and related measures. Convergent validity was assessed with a subjective questionnaire about beliefs about medicines (BMQ Specific, two sub-scales). RESULTS A total of 70 patients were included (mean age 65.7 ± 9.9 years; 31.4% women). The mean score of the MMAS-8D was 7.5 (SD 0.8; range 4.5-8). Moderate internal consistency (alpha = 0.31) was observed due to multidimensionality of the scale. Factor analysis yielded four components that accounted for 71.7% of the total variance. Convergent validity was supported by significant correlations with BMQ Necessity (r = 0.31, P < 0.01), BMQ Concerns (r = -0.16, P < 0.05) and with electronic adherence reports (U-values 44 and 471, P < 0.05). Platelet aggregation values were within therapeutic range for 80% of the patients. Blood values of the antiplatelet agent within therapeutic range were associated with a higher MMAS-8D score (U-value 125, P < 0.05). CONCLUSIONS The German MMAS-8 appears to be a reliable instrument to catch medication adherence in cardiovascular patients. It may be useful in patients with chronic therapy for detecting non-adherence.

Assessing adherence factors in patients under topical treatment: development of the Topical Therapy Adherence Questionnaire (TTAQ). Arch Dermatol Res 2014; 306:287-97. [PMID: 24509981 PMCID: PMC3955139 DOI: 10.1007/s00403-014-1446-x] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2013] [Revised: 01/16/2014] [Accepted: 01/20/2014] [Indexed: 11/03/2022]
Abstract
Medication adherence rates strongly depend on favorable disease outcomes. It is known that medication adherence rates are lower for topical treatment than for systemic treatment. However, to date no validated instrument for the assessment of adherence factors in topical treatment is available. The aim of this study was to develop a new questionnaire to assess adherence risk factors in topical treatment. The development of the Topical Therapy Adherence Questionnaire (TTAQ) and Patient Preference Questionnaire (PPQ) was based on a systematic literature review, and qualitative patient focus interviews and expert focus groups’ input. The psychometric properties and comprehensibility of the TTAQ and PPQ were assessed in a feasibility study with 59 psoriasis patients. Our first preliminary results indicate that the TTAQ and PPQ are psychometrically sound and reliable measures for the assessment of factors influencing topical treatment adherence. The questionnaires are currently being further developed and various parameters (e.g., time point of assessment) are currently being tested in an exploratory pilot study with ca. 2,000 psoriasis patients receiving topical treatment in a European clinical trial. The use of the final versions of TTAQ and PPQ in clinical practice may facilitate the early identification of specific non-adherence factors in patients under topical treatment, which could enable designing and applying adherence-enhancing interventions according to the patient’s individual needs.

Abstract
BACKGROUND As the population ages, the relative and absolute number of age-associated diseases such as dementia will increase. Evaluation of the suitability and intake of medication and pharmacological treatment is an important aspect of care for people with dementia, especially if they live at home. Regular medication reviews and systematic cooperation between physicians and pharmacists are not common in routine care. Medication management (MM), based on such a comprehensive home medication review could help to reduce drug-related problems and costs. The present article presents a medication management specifically for the application in the ambulatory setting and describes its implementation as part of a larger trial. METHODS/DESIGN A home medication review (HMR) and MM is implemented as part of the DelpHi study, a population based prospective, cluster-randomized controlled intervention study to test the efficacy and efficiency of the implementation of a collaborative care model in primary care. PARTICIPANTS people with dementia (PWD) and their caregivers are recruited by the patient's general practitioner. Inclusion criteria are a positive screening result for dementia, living at home and regular intake of drugs. PWD are asked to specify their regular pharmacy which is asked to participate in the study, too. INTERVENTION a comprehensive HMR is conducted as computer-assisted personal interview by specifically qualified Dementia Care Manager (DCM) at the people's home. It includes detailed information about drugs taken, their storage, administration, adherence and adverse events. The MM is conducted in cooperation between DCM, pharmacist and general practitioner and consists of a pharmaceutical evaluation, pharmaceutical recommendations and their application. Pharmacists are trained and provided with regularly updated information. The MM is designed to give information and recommendations concerning antidementia drugs, occurrence of drug related problems, intake of anticholinergic drugs, potentially clinically relevant drug-drug-interactions, adverse drug events and medication adherence. DISCUSSION The DelpHi-approach for medication management employs comprehensive instruments and procedures in the primary care setting under routine care conditions, and this approach should be useful in improving pharmacotherapy as part of the comprehensive treatment and care for people with dementia. TRIAL REGISTRATION The trial is registered at ClinicalTrials.gov, number NCT01401582.

Adherence to antihypertensives: feasibility of two self-report instruments to investigate medication-taking behaviour in German community pharmacies. INTERNATIONAL JOURNAL OF PHARMACY PRACTICE 2012; 21:169-77. [DOI: 10.1111/j.2042-7174.2012.00248.x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2011] [Accepted: 09/14/2012] [Indexed: 01/06/2023]
Abstract
Abstract
Objective
To design and test the feasibility of two questionnaires in German community pharmacies exploring self-reported adherence to antihypertensives.
Methods
Two self-report questionnaires were designed for patients treated with antihypertensives. The 29-item-questionnaire (long form, LF) was completed by pharmacists interviewing patients who were on the premises filling a prescription. The short form (SF; 19 items) was sent by pharmacies to patients via mail. The acceptance of the instruments by patients and pharmacists as well as the feasibility to measure medication-taking behaviour was investigated. Adherence was investigated by using a modified 5-(LF) or 6-item (SF) Morisky score.
Results
Of 44 community pharmacies contacted, 18 agreed to participate. Patients' response rates were 428/915 (46.8%) for the SF and 249/760 (32.8%) for the LF. One hundred and seventy-nine patients (41.8%) and 70 patients (28.1%) reported adherence problems according to the SF and LF respectively.
Conclusions
To our knowledge, this is the first attempt to develop a self-report instrument for the detection of non-adherence in patients taking antihypertensives in this setting in Germany. Patients were willing to provide detailed information about their medication-taking behaviour. Underestimation of non-adherence may be more pronounced when applying the questionnaire in the pharmacy.

Selection of tools for reconciliation, compliance and appropriateness of treatment in patients with multiple chronic conditions. Eur J Intern Med 2012; 23:506-12. [PMID: 22863426 DOI: 10.1016/j.ejim.2012.06.007] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2012] [Revised: 06/06/2012] [Accepted: 06/06/2012] [Indexed: 11/28/2022]
Abstract
BACKGROUND The healthcare models developed for patients with multiple chronic diseases agree on the need for improving drug therapy in these patients. The issues of patient compliance, appropriateness of prescriptions and the reconciliation process are of vital importance for patients receiving multiple drug treatment. OBJECTIVE To identify and select the most appropriate tools for measuring treatment compliance and appropriateness in multiple-disease patients, as well as the best reconciliation strategy. METHODS The study used the Delphi methodology. We identified compliance and appropriateness questionnaires and scales, as well as functional organisation models for reconciliation that had been used in patients with multiple chronic conditions. Based on the strength of the evidence, their usefulness in these patients and ease of use, the panel selected the most appropriate ones. RESULTS We selected 46 indications for the panel: 5 on compliance, 20 on appropriateness, and 31 on reconciliation. The tool considered most appropriate and with a high degree of agreement was the "Adherence to Refills and Medication Scale" questionnaire. For appropriateness, the Medication Appropriateness Index questionnaire was considered appropriate. The STOPP/START criteria were the most appropriate. The greatest degree of agreement regarding reconciliation was on the information that needed to be collected and the variables considered as discrepancies. CONCLUSIONS The "Adherence to Refills and Medication Scale" questionnaire for compliance, the STOPP/START criteria, the Medication Appropriateness Index questionnaire for appropriateness and the development of a specific strategy for reconciliation were considered appropriate for the assessment of drug therapy in patients with multiple chronic conditions.

Validity of the adherence estimator in the prediction of 9-month persistence with medications prescribed for chronic diseases: a prospective analysis of data from pharmacy claims. Clin Ther 2010; 31:2584-607.

Abstract
OBJECTIVE The aim of this article was to assess the predictive validity of the Adherence Estimator--a 3-item instrument designed to estimate a patient's propensity to adhere to medications prescribed for chronic disease. METHODS The Adherence Estimator was a 3-item part of a larger survey mailed to adults aged >or=40 years who had a qualifying index prescription filled in June 2008. A qualifying prescription was defined as one for a medication indicated for the treatment of 1 of 5 chronic diseases (cardiovascular disease, dyslipidemia [lipid-lowering drugs], diabetes [oral antihyperglycemics], osteoporosis [oral bisphosphonates], or asthma). Outcomes were compared between the adherence risk groups derived from the Adherence Estimator (low risk = score of 0, medium risk = score of 2-7, and high risk = score of 8-36). Treatment persistence over a period of 9 months was measured using pharmacy claims data. The primary outcome was the median proportion of days covered (PDC) by >or=1 medication during the first 9 months after the index fill. Secondary outcomes included adherence to the index medication, defined as PDC dichotomized to >or=0.80 or <0.80; rate of obtaining a second fill within 30 days of the index fill; and medication possession ratio (MPR) for refill adherence. RESULTS There were 1676 usable responses. Ages ranged from 40 to 88 years, with a mean of 64.6 years. Almost two thirds (1076/1676 [64.2%]) of the sample were female, and 1483/1676 (88.5%) were white. Statistically significant associations for all 3 pairwise comparisons (low vs medium risk, low vs high risk, and medium vs high risk) were observed between the Adherence Estimator risk groups for: (1) median PDC (0.655, 0.598, and 0.484 in the low-, medium-, and high-risk groups, respectively [all, false discovery rate [FDR] <0.05]); (2) PDC categorized (293/711 [41.21%], 200/588 [34.01%], and 105/377 [27.85%] [all, FDR <0.05]); and (3) rate of obtaining a second fill for the index medication within 30 days (489/711 [68.78%], 374/588 [63.61%], and 207/377 [54.91%] [all, FDR <0.05]). The low- and high-risk groups differed from one another on: (1) persistence with the index medication at 9 months (265/711 [37.27%] and 95/377 [25.20%]); (2) persistence with >1 medication at 9 months (291/711 [40.93%] and 108/377 [28.65%]); and (3) obtaining a second fill for any medication within 30 days (501/711 [70.46%] and 219/377 [59.09%]) (all, P < 0.05). The low- and high-risk groups differed significantly from one another in MPR for refill adherence (0.912 vs 0.866). Results observed within diseases mirrored those for the total sample, but with less precision. CONCLUSION In the present analysis of the validity of the Adherence Estimator in predicting adherence, baseline propensity to adhere to medications prescribed for chronic diseases was statistically associated with several measures of adherence and persistence, as derived from pharmacy claims data, over a 9-month period.
