Khartabil N, Morello CM, Macedo E. Predictive Modeling of Factors Influencing Adherence to SGLT-2 Inhibitors in Ambulatory Care: Insights from Prescription Claims Data Analysis. PHARMACY 2024; 12:72. [PMID: 38668098 PMCID: PMC11054968 DOI: 10.3390/pharmacy12020072] [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: 02/06/2024] [Revised: 03/12/2024] [Accepted: 04/07/2024] [Indexed: 04/29/2024] Open
Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are novel oral anti-hyperglycemic drugs that demonstrate cardiovascular and metabolic benefits for patients with type 2 diabetes (T2D), heart failure (HF), and chronic kidney disease (CKD). There is limited knowledge of real-world data to predict adherence to SGLT-2i in an ambulatory setting. The study aims to predict SGLT-2i adherence in patients with T2D and/or HF and/or CKD by building a prediction model using electronic prescription claims data presented within EPIC datasets. This is a retrospective study of 174 adult patients prescribed SGLT-2i at UC San Diego Health ambulatory pharmacies between 1 January 2020 to 30 April 2021. Adherence was measured by the proportion of days covered (PDC). R packages were used to identify regression and non-linear regression predictive models to predict adherence. Age, gender, race/ethnicity, hemoglobin A1c, and insurance plan were included in the model. Diabetes control based on hemoglobin A1c (HbA1c) and the glomerular filtration rate (GFR) was also evaluated using Welch t-test with a p-value of 0.05. The best predictive model for measuring adherence was the simple decision tree. It had the highest area under the curve (AUC) of 74% and accuracy of 82%. The model accounted for 21 variables with the main node predictors, including glycated hemoglobin, age, gender, and insurance plan payment amount. The adherence rate was inversely proportional to HbA1c and directly proportional to the plan payment amount. As for secondary outcomes, HbA1c values from baseline till 90 days post-treatment duration were consistently higher in the non-compliant group: 7.4% vs. 9.6%, p < 0.001 for the PDC ≥ 0.80 and PDC < 0.80, respectively. Baseline eGFR was 55.18 mL/min/1.73m2 vs. 54.23 mL/min/m2 at 90 days. The mean eGFR at the end of the study (minimum of 90 days of treatment) was statistically different between the groups: 53.1 vs. 59.6 mL/min/1.73 m2, p < 0.001 for the PDC ≥ 0.80 and PDC < 0.80, respectively. Adherence predictive models will help clinicians to tailor regimens based on non-adherence risk scores.

Co-Design, Development, and Evaluation of a Mobile Solution to Improve Medication Adherence in Cancer: Design Science Research Approach. JMIR Cancer 2024; 10:e46979. [PMID: 38569178 PMCID: PMC11024750 DOI: 10.2196/46979] [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: 03/04/2023] [Revised: 01/27/2024] [Accepted: 02/14/2024] [Indexed: 04/05/2024] Open
Abstract
BACKGROUND Medication nonadherence negatively impacts the health outcomes of people with cancer as well as health care costs. Digital technologies present opportunities to address this health issue. However, there is limited evidence on how to develop digital interventions that meet the needs of people with cancer, are perceived as useful, and are potentially effective in improving medication adherence. OBJECTIVE The objective of this study was to co-design, develop, and preliminarily evaluate an innovative mobile health solution called Safety and Adherence to Medication and Self-Care Advice in Oncology (SAMSON) to improve medication adherence among people with cancer. METHODS Using the 4 cycles and 6 processes of design science research methodology, we co-designed and developed a medication adherence solution for people with cancer. First, we conducted a literature review on medication adherence in cancer and a systematic review of current interventions to address this issue. Behavioral science research was used to conceptualize the design features of SAMSON. Second, we conducted 2 design phases: prototype design and final feature design. Last, we conducted a mixed methods study on patients with hematological cancer over 6 weeks to evaluate the mobile solution. RESULTS The developed mobile solution, consisting of a mobile app, a web portal, and a cloud-based database, includes 5 modules: medication reminder and acknowledgment, symptom assessment and management, reinforcement, patient profile, and reporting. The quantitative study (n=30) showed that SAMSON was easy to use (21/27, 78%). The app was engaging (18/27, 67%), informative, increased user interactions, and well organized (19/27, 70%). Most of the participants (21/27, 78%) commented that SAMSON's activities could help to improve their adherence to cancer treatments, and more than half of them (17/27, 63%) would recommend the app to their peers. The qualitative study (n=25) revealed that SAMSON was perceived as helpful in terms of reminding, supporting, and informing patients. Possible barriers to using SAMSON include the app glitches and users' technical inexperience. Further needs to refine the solution were also identified. Technical improvements and design enhancements will be incorporated into the subsequent iteration. CONCLUSIONS This study demonstrates the successful application of behavioral science research and design science research methodology to design and develop a mobile solution for patients with cancer to be more adherent. The study also highlights the importance of applying rigorous methodologies in developing effective and patient-centered digital intervention solutions.

Patient adherence to an oral rehydration solution intervention to prevent dehydration following ileostomy creation: A qualitative study. Am J Surg 2024:S0002-9610(24)00156-9. [PMID: 38448319 DOI: 10.1016/j.amjsurg.2024.02.045] [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: 01/05/2024] [Revised: 02/14/2024] [Accepted: 02/27/2024] [Indexed: 03/08/2024]
Abstract
BACKGROUND Patients undergoing surgery for ileostomy creation frequently experience postoperative dehydration and subsequent renal injury. The use of oral rehydration solutions (ORS) has been shown to prevent dehydration, but compliance may be variable. METHODS Semi-structured qualitative interviews were conducted with 17 patients who received a postoperative hydration kit and dehydration education to assess barriers and facilitators to compliance with ORS kit instructions. RESULTS Qualitative analysis revealed five themes affecting patient adherence to the ORS intervention: (1) patient's perception of the effectiveness of the ORS solution, (2) existing co-morbidities, (3) kit quality and taste of the ORS product, (4) quality of the dehydration education, and (5) social support. CONCLUSIONS Given that patient adherence can greatly affect the success of an ORS intervention, the design of future ORS interventions should emphasize the educational component, the "patient friendliness" of the ORS kit, and ways that social supports can be leveraged to increase adherence.

Identifying determinants of adherence to adjuvant endocrine therapy following breast cancer: A systematic review of reviews. Cancer Med 2024; 13:e6937. [PMID: 38240343 PMCID: PMC10905548 DOI: 10.1002/cam4.6937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 11/01/2023] [Accepted: 12/17/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND In oestrogen-receptor positive breast cancer, daily oral adjuvant endocrine therapy (ET) for at least 5 years significantly reduces risks of recurrence and breast cancer-specific mortality. However, many women are poorly adherent to ET. Development of effective adherence support requires comprehensive understanding of influences on adherence. We undertook an umbrella review to identify determinants of ET adherence. METHODS We searched PubMed, Embase, CINAHL, PsycINFO, Cochrane and PROSPERO (inception to 08/2022) to identify systematic reviews on factors influencing ET adherence. Abstracted determinants were mapped to the World Health Organization's dimensions of adherence. Reviews were quality appraised and overlap assessed. RESULTS Of 5732 citations screened, 17 reviews were eligible (9 quantitative primary studies; 4 qualitative primary studies; 4 qualitative or quantitative studies) including 215 primary papers. All five WHO dimensions influenced ET non-adherence: The most consistently identified non-adherence determinants were patient-related factors (e.g. lower perceived ET necessity, more treatment concerns, perceptions of ET 'cons' vs. 'pros'). Healthcare system/healthcare professional-related factors (e.g. perceived lower quality health professional interaction/relationship) were also important and, to a somewhat lesser extent, socio-economic factors (e.g. lower levels of social/economic/material support). Evidence was more mixed for medication-related and condition-related factors, but several may be relevant (e.g. experiencing side-effects, cost). Potentially modifiable factors are more influential than non-modifiable/fixed factors (e.g. patient characteristics). CONCLUSIONS The evidence-base on ET adherence determinants is extensive. Future empirical studies should focus on less well-researched areas and settings. The determinants themselves are numerous and complex in indicating that adherence support should be multifaceted, addressing multiple determinants.

Effect of single-administration of D-sorbitol pretreatment on the bitterness and continued willingness to take asenapine: a randomized, single-blind, placebo-controlled, crossover trial. BMC Psychiatry 2024; 24:81. [PMID: 38291403 PMCID: PMC10829201 DOI: 10.1186/s12888-024-05549-x] [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: 10/03/2023] [Accepted: 01/23/2024] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND Asenapine has unique orally-related side effects, such as a bitter taste induced by sublingual administration, which often results in discontinuation of the medication. While the FDA has approved black-cherry-flavored asenapine, several countries have prescribed only unflavored versions. Specifically, Asians commonly report experiencing the bitterness of asenapine because they are more sensitive to bitter tastes than other ethnic groups. In this study, with the aim of improving adherence by reducing the bitterness of asenapine, we investigated the effects of D-sorbitol, which reduced the bitterness parameters of taste sensors in our previous basic study on the bitterness and continuity of asenapine among patients with schizophrenia. METHODS Twenty adult patients with schizophrenia were included in this single-blind, placebo-controlled, crossover trial. Participants rinsed their mouths with single-administration of D-sorbitol or a placebo prior to each administration of asenapine. We then conducted the questionnaires and assessed changes in the bitterness of asenapine (primary end point) and willingness to continue its use (secondary end point). RESULTS D-sorbitol significantly improved the bitterness of asenapine (p = 0.038). Although it did not significantly increase the willingness to continue asenapine (p = 0.180), it did show improvement over the placebo in enhancing willingness to continue, especially in patients who were not accustomed to its taste. CONCLUSION Our findings indicate that single-administration of D-sorbitol significantly reduces the bitterness of asenapine. In countries where flavored asenapine is not available, this finding could benefit patients who were not accustomed to its bitter taste. TRIAL REGISTRATION This study was registered in the Japan Registry of Clinical Trials (jRCTs041210019) on May 14, 2021.

Abstract
BACKGROUND People with memory disorders have difficulty adhering to treatments. With technological advances, it remains important to investigate the potential of health information technology (HIT) in supporting medication adherence among them. OBJECTIVES This review investigates the role of HIT in supporting adherence to medication and therapies among patients with memory issues. It also captures the factors that impact technology adherence interventions. METHODS We searched the literature for relevant publications published until March 15, 2023, using technology to support adherence among patients with memory issues (dementia, Alzheimer's, amnesia, mild cognitive impairment, memory loss, etc.). The review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We conducted a quality assessment of the papers following the Mixed Methods Appraisal Tool. RESULTS Fifteen studies were included after carefully reviewing the 3,773 articles in the search. Methodological quality, as appraised, ranged from 80 to 100% with eight studies rated 100%. The studies overall did not have a high risk of bias. Thus, all of the 15 studies were included. Technologies investigated were classified into four groups based on their impact: therapeutic patient education, simplifying treatment regimens, early follow-up visits and short-term treatment goals, and reminder programs. Different technologies were used (automatic drug dispensers or boxes, mobile health-based interventions, game-based interventions, e-health-based interventions, patient portals, and virtual reality). The factors impacting patients' adherence to technology-based treatment and medication were clustered into human-computer interaction and integration challenges. CONCLUSION This study contributes to the literature by classifying the technologies that supported medication adherence among patients with memory issues in four groups. It also explores and presents the possible limitations of existing solutions to drive future research in supporting care for people with memory disorders.

Abstract
BACKGROUND Missed colonoscopy appointments delay screening and treatment for gastrointestinal disorders. Prior nonadherence with other care components may be associated with missed colonoscopy appointments. OBJECTIVE To assess variability in prior adherence behaviors and their association with missed colonoscopy appointments. DESIGN Retrospective cohort study. PARTICIPANTS Patients scheduled for colonoscopy in an integrated healthcare system between January 2016 and December 2018. MAIN MEASURES Prior adherence behaviors included: any missed outpatient appointment in the previous year; any missed gastroenterology clinic or colonoscopy appointment in the previous 2 years; and not obtaining a bowel preparation kit pre-colonoscopy. Other sociodemographic, clinical, and system characteristics were included in a multivariable model to identify independent associations between prior adherence behaviors and missed colonoscopy appointments. KEY RESULTS The median age of the 57,590 participants was 61 years; 52.8% were female and 73.4% were white. Of 77,684 colonoscopy appointments, 3,237 (4.2%) were missed. Individuals who missed colonoscopy appointments were more likely to have missed a previous primary care appointment (62.5% vs. 38.4%), a prior gastroenterology appointment (18.4% vs. 4.7%) or not to have picked up a bowel preparation kit (42.4% vs. 17.2%), all p < 0.001. Correlations between the three adherence measures were weak (phi < 0.26). The rate of missed colonoscopy appointments increased from 1.8/100 among individuals who were adherent with all three prior care components to 24.6/100 among those who were nonadherent with all three care components. All adherence variables remained independently associated with nonadherence with colonoscopy in a multivariable model that included other covariates; adjusted odds ratios (with 95% confidence intervals) were 1.6 (1.5-1.8) for outpatient appointments, 1.9 (1.7-2.1) for gastroenterology appointments, and 3.1 (2.9-3.4) for adherence with bowel preparation kits, respectively. CONCLUSIONS Three prior adherence behaviors were independently associated with missed colonoscopy appointments. Studies to predict adherence should use multiple, complementary measures of prior adherence when available.

Abstract
OBJECTIVES Today, the involvement of patients in their care is essential. As the population ages increases, the number of patients with chronic diseases is increasing. In the vascular medicine and surgery departments, patients are polymedicated and mostly suffer from several chronic diseases. Approximately 50% of patients with a chronic disease are not adherent. Among the factors that can influence therapeutic adherence are the beliefs and representations of patients.To evaluate the beliefs and representations of chronic treatments in patients with multiple medications and hospitalised in a vascular medicine and surgery department, and to evaluate the medication adherence, the knowledge and the importance patients attach to their treatments. DESIGN Observational, prospective and a single-centre study. SETTING The study was conducted in a French tertiary hospital centre of around 3000 beds in 9 institutions. PARTICIPANTS Adult polymedicated (ie, minimum of five chronic treatments) patients hospitalised in a vascular medicine and surgery department were included after application of the exclusion criteria. METHODS Patient interviews were carried out in the department and were based on three interviewer-administered questionnaires (a global questionnaire, the Belief Medical Questionnaire and the GIRERD questionnaire). RESULTS Our study showed that patients perceived their treatments as beneficial rather than worrying. A correlation between medication adherence and beliefs was observed. 'Non-adherent'patients had a more negative overall view of medication than 'adherent' patients. The level of compliance and knowledge of our patients was low. Only 11% of the patients were 'good adherent', 16% of the patients could perfectly name their treatment and 36% knew all the indications. CONCLUSION Knowledge of treatment representation and beliefs are central to understanding patient behaviour. Considering patients' representations will allow the identification of levers, and the development of actions and educational tools adapted to improve their adherence, their knowledge and therefore their drug management.

Abstract
BACKGROUND A better understanding of patient non-adherence to type 2 diabetes medication is needed to design effective interventions to address this issue. OBJECTIVES (1) To estimate the prevalence of non-adherence to diabetes medication; (2) to examine its impact on glycemic control and insulin initiation; (3) to develop and validate a prediction model of non-adherence. METHODS We conducted a longitudinal cohort study based on data from electronic health records. We included adult patients registered within the Health Service of the Balearic Islands (Spain) starting a new prescription of a non-insulin glucose-lowering drug between January 2016 and December 2018. We calculated non-adherence at 12 months follow-up, defined as medication possession ratio (MPR) ≤ 80%. We fitted multivariable regression models to examine the association between non-adherence and glycemic control and insulin initiation and identified predictors of non-adherence. RESULTS Of 18,119 patients identified, after 12 months follow-up, 5,740 (31.68%) were non-adherent. Compared with non-adherent, adherent patients presented lower HbA1c levels (mean difference = -0.32%; 95%CI = -0.38%; -0.27%) and were less likely to initiate insulin (aOR = 0.77; 95%CI = 0.63; 0.94). A predictive model explained 22.3% of the variation and presented a satisfactory performance (AUC = 0.721; Brier score = 0.177). The most important predictors of non-adherence were: non-Spanish nationality, currently working, low adherence to previous drugs, taking biguanides, smoker and absence of hypertension. CONCLUSION Around one-third of the patients do not adhere to their non-insulin glucose-lowering drugs. More research is needed to optimise the performance of the predicting model before considering its implementation in routine clinical practice.

Rates of adherence to cancer treatment guidelines in Australia and the factors associated with adherence: A systematic review. Asia Pac J Clin Oncol 2023; 19:618-644. [PMID: 36881529 DOI: 10.1111/ajco.13948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/01/2023] [Accepted: 02/03/2023] [Indexed: 03/08/2023]
Abstract
Adherence to cancer treatment clinical practice guidelines (CPGs) varies enormously across Australia, despite being associated with improved patient outcomes. This systematic review aims to characterize adherence rates to active-cancer treatment CPGs in Australia and related factors to inform future implementation strategies. Five databases were systematically searched, abstracts were screened for eligibility, a full-text review and critical appraisal of eligible studies performed, and data extracted. A narrative synthesis of factors associated with adherence was conducted, and the median adherence rates within cancer streams calculated. A total of 21,031 abstracts were identified. After duplicates were removed, abstracts screened, and full texts reviewed, 20 studies focused on adherence to active-cancer treatment CPGs were included. Overall adherence rates ranged from 29% to 100%. Receipt of guideline recommended treatments was higher for patients who were younger (diffuse large B-cell lymphoma [DLBCL], colorectal, lung, and breast cancer); female (breast and lung cancer), and male (DLBCL and colorectal cancer); never smokers (DLBCL and lung cancer); non-Indigenous Australians (cervical and lung cancer); with less advanced stage disease (colorectal, lung, and cervical cancer), without comorbidities (DLBCL, colorectal, and lung cancer); with good-excellent Eastern Cooperative Oncology Group performance status (lung cancer); living in moderately accessible places (colon cancer); and; treated in metropolitan facilities (DLBLC, breast and colon cancer). This review characterized active-cancer treatment CPG adherence rates and associated factors in Australia. Future targeted CPG implementation strategies should account for these factors, to redress unwarranted variation particularly in vulnerable populations, and improve patient outcomes (Prospero number: CRD42020222962).

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) are routinely prescribed complex medication regimes. Medication reconciliation, medicine reviews, patient counselling and disease state and medication education are all key pharmacist-led interventions, which can improve medication adherence in patients with CKD. AIM To characterize peer reviewed literature on the role of pharmacists in supporting medication adherence of patients with chronic kidney disease and highlight the impact they might have in the health outcomes for patients. METHOD This review was performed in accordance with the Scoping Review Framework outlined in the Joanna Briggs Institute Reviewer's Guide. Four electronic databases were searched (Medline (Ovid), Emcare, Scopus and Web of Science) for all relevant literature published up until November 2022. A total of 32 studies were reviewed against an exclusion and inclusion criteria, with findings from each study categorized into barriers, interventions, perceptions, financial implications and outcomes. RESULTS Eight eligible studies were identified, where pharmacists' interventions including medication reconciliation, medicine reviews, patient counselling and disease state and medication education, were all reported to have a positive effect on medication adherence. Although pharmacy services in chronic kidney disease were acceptable to patients and pharmacists, these services were under-utilized and limited by logistical constraints, including staffing shortages and time limitations. Patient education supplemented with education tools describing disease states and medications was reported to increase patient adherence to medication regimes. CONCLUSIONS Pharmacist-led interventions play an integral role in improving medication adherence in patients with chronic kidney disease, with their inclusion in renal care settings having the potential to improve outcomes for patients.

Abstract
New approaches to medication adherence interventions are needed. This manuscript presents a highly structured protocol of a single-session solution-focused brief therapy (SFBT) for medication adherence intervention (SFBT-MAI) delivered by general providers. It conceptually integrates the procedure of tailored interventions, techniques of SFBT, and the four steps of Qitang Lin' conceptualization of single-session SFBT. With specific techniques and examples to reduce operational difficulties, the SFBT-MAI includes two parts. The first part focuses on selecting non-adherent patients and clarifying their barriers to medication adherence. The second part focuses on individualized interventions with four steps: closing, hoping, empowering, and changing and acting. It is hoped that this work will improve the effectiveness of medication adherence interventions for patients with coronary heart disease and to promote the use of brief psychological interventions in clinical practice.

Abstract
PURPOSE Medication non-adherence is a well-recognised problem in cancer care, negatively impacting health outcomes and healthcare resources. Patient-related factors influencing medication adherence (MA) are complicated and interrelated. There is a need for qualitative research to better understand their underlying interaction processes and patients' needs to facilitate the development of effective patient-tailored complex interventions. This study aimed to explore experiences, perceptions, and needs relating to MA and side effect management of patients who are self-administering anti-cancer treatment. METHODS Semi-structured audio-recorded interviews with patients who have haematological cancer were conducted. A comparative, iterative, and predominantly inductive thematic analysis approach was employed. RESULTS Twenty-five patients from a specialist cancer hospital were interviewed. While self-administering cancer medications at home, patients' motivation to adhere was affected by cancer-related physical reactions, fears, cancer literacy and beliefs, and healthcare professional (HCP) and informal support. Patients desired need for regular follow-ups from respectful, encouraging, informative, responsive, and consistent HCPs as part of routine care. Motivated patients can develop high adherence and side effect self-management over time, especially when being supported by HCPs and informal networks. CONCLUSION Patients with cancer need varied support to medically adhere to and manage side effects at home. HCPs should adapt their practices to meet the patients' expectations to further support them during treatment. We propose a multi-dimensional and technology- and theory-based intervention, which incorporates regular HCP consultations providing tailored education and support to facilitate and maintain patient MA and side effect self-management.

Factors influencing adherence to non-communicable disease medication in India: secondary analysis of cross-sectional data from WHO - SAGE2. Front Pharmacol 2023; 14:1183818.

Abstract
Background: Non-communicable diseases (NCDs) are a leading cause of death globally and disproportionately affect those in low- and middle-income countries lower-middle-income countries. Poor medication adherence among patients with NCDs is prevalent in India due to lack of initiation, missed dosing or cessation of treatment, and represents a growing healthcare and financial burden. Objective: This study aimed to identify factors influencing medication adherence in adults with NCDs in India. Methods: We performed a cross-sectional study, conducting secondary data analysis on the second wave of the World Health Organisation's 'Study on global AGEing and adult health (SAGE)', a survey that collected data from predominantly older adults across India. Bivariate analysis and multivariate logistic regression modelling were conducted to specifically interrogate the reasons for lack of initiation and cessation of treatment. Reporting of this study was informed by the STROBE guidelines. Results: The average medication adherence rate was 51% across 2,840 patients with one or more NCDs, reflecting non-initiation and lack of persistence of treatment. The strongest factor significantly predicting non-adherence to medication across these components was multimorbidity (odds ratio 0.47, 95% CI 0.40-0.56). Tobacco use (OR = 0.76, CI 0.59-0.98) and never having attended school (OR = 0.75, CI 0.62-0.92) were significantly associated with poor medication adherence (p < 0.05) while rural living (OR = 0.70, CI 0.48-1.02), feelings of anxiety (OR = 0.84, CI 0.66-1.08) and feelings of depression (OR = 0.90, CI 0.70-1.16) were factors lacking statistically significant association with medication adherence on multivariate analysis. Older age (OR = 2.02, CI 1.51-2.71) was significantly associated with improved medication adherence whilst there was a weak association between increased wealth and improved medication use. Limitations: The SAGE2 survey did not capture whether patients were taking their medication doses according to prescribed instructions-as a result our findings may under-estimate the true prevalence of medication non-adherence. Conclusion: Our analysis provides evidence that poor medication adherence in India is multifactorial, with distinct socioeconomic and health-system factors interacting to influence patient decision making. Future large-scale surveys interrogating adherence should assess all components of adherence specifically, whilst public health interventions to improve medication adherence should focus on barriers that may exist due to multimorbidity, comorbid depression and anxiety, and low educational status.

Abstract
The growing burden of non-communicable diseases amidst the largest burden of HIV in South Africa leads to disease combinations of multimorbidity with the complexity of care. We conducted a cross-sectional study to assess multimorbidity, medication adherence, and associated factors among out-patients with chronic diseases in primary health care (PHC) facilities in Tshwane, South Africa. A structured questionnaire was used to collect data on comorbidities and medication adherence, along with socio-demographic and lifestyle factors. Logistic regression models were used to analyse the determinants of multimorbidity and medication adherence. In all 400 patients with chronic diseases (mean age: 47 ± 12 years) living in poor environments, common chronic conditions were hypertension (62%), diabetes (45%), HIV (44%), TB (33%), hypercholesterolemia (18%), and gout (13%). The proportion of concordant comorbidity (i.e., diseases with similar risk profiles and management) was 72%, more than 28% of discordant comorbidity (i.e., diseases not related in pathogenesis or management). Most patients had two coexisting chronic conditions (75%), while few had more than two chronic conditions (23%) and single-occurring conditions (2%). Prevalence rates for common multimorbidity patterns were 25% (HIV and TB), 17% (hypertension and diabetes), 9% (hypertension, diabetes, and hypercholesterolemia), and 2% (hypertension diabetes and HIV), while medication adherence was estimated at 74%. In multivariate analysis, multimorbidity was associated with an older age and lower socio-economic status, while medication non-adherence was associated with a younger age and socio-economic factors. The study highlights the presence of multimorbidity among primary care patients attributed to hypertension, diabetes, HIV, and TB in South Africa with non-adherence to medication in one-third of patients. Policies are needed for education on multimorbidity with a need to optimize lifestyle modifications, perhaps proactive outreach or nursing contact with high-risk patients with public-health-sensitive conditions, such as HIV and/or TB, as well as patients with a history of non-adherence to medications. Considerations should be given to the development of a medication adherence scale for multiple chronic conditions beyond assessing adherence to a single index medication.

Abstract
OBJECTIVES Poor medication adherence in low-income and middle-income countries is a major cause of suboptimal hypertension and diabetes control. We aimed to identify key factors associated with medication adherence in western Kenya, with a focus on cost-related and economic wealth factors. SETTING We conducted a cross-sectional analysis of baseline data of participants enrolled in the Bridging Income Generation with Group Integrated Care study in western Kenya. PARTICIPANTS All participants were ≥35 years old with either diabetes or hypertension who had been prescribed medications in the past 3 months. PRIMARY AND SECONDARY OUTCOME MEASURES Baseline data included sociodemographic characteristics, wealth and economic status and medication adherence information. Predictors of medication adherence were separated into the five WHO dimensions of medication adherence: condition-related factors (comorbidities), patient-related factors (psychological factors, alcohol use), therapy-related factors (number of prescription medications), economic-related factors (monthly income, cost of transportation, monthly cost of medications) and health system-related factors (health insurance, time to travel to the health facility). A multivariable analysis, controlling for age and sex, was conducted to determine drivers of suboptimal medication adherence in each overarching category. RESULTS The analysis included 1496 participants (73.7% women) with a mean age of 60 years (range 35-97). The majority of participants had hypertension (69.2%), 8.8% had diabetes and 22.1% had both hypertension and diabetes. Suboptimal medication adherence was reported by 71.2% of participants. Economic factors were associated with medication adherence. In multivariable analysis that investigated specific subtypes of costs, transportation costs were found to be associated with worse medication adherence. In contrast, we found no evidence of association between monthly medication costs and medication adherence. CONCLUSION Suboptimal medication adherence is highly prevalent in Kenya, and primary-associated factors include costs, particularly indirect costs of transportation. Addressing all economic factors associated with medication adherence will be important to improve outcomes for non-communicable diseases. TRIAL REGISTRATION NUMBER NCT02501746.

BACKGROUND The psychological burden in people with inflammatory arthritis is substantial, yet little is known about the disease-related affect experienced by individuals with axial Spondyloarthritis (axial SpA). The aim of this study was to conduct a qualitative evidence synthesis and a review of social media to explore the emotional impact of living with axial SpA. METHODS We searched nine databases for studies reporting qualitative data about participants' emotional experience of living with axial SpA. In addition, we searched social media platforms for posts from people with axial SpA based in the UK that offered insights into emotional responses to living with the condition. We employed a thematic approach to synthesise the data. RESULTS We included 27 studies (1314 participants; 72% men) in our qualitative evidence synthesis and developed seven descriptive themes from the data: 1) delayed diagnosis: a barrier to emotional wellbeing; 2) disruptive symptoms: a source of mood swings; 3) work disability: a loss of self-esteem; 4) obstacles in interpersonal relationships: a trigger of distress; 5) taking up exercise: personal pride or unwelcomed reminders; 6) anti-TNF therapy: hope reignited despite concerns and 7) a journey of acceptance: worry mixed with hope. Posts extracted from social media fora (537; 48% from women) for the most part supported the seven themes. One additional theme-COVID-19, uncertainty and anxiety during the pandemic, was developed, reflecting common emotions expressed during the UK's first wave of the coronavirus pandemic. CONCLUSION This study highlights a preponderance of negative affect experienced by people living with axial SpA, conditioned through existing and anticipated symptoms, failed expectations, and lost sense of self. Given the bidirectional relationships between negative emotions and inflammation, negative emotions and perceptions of pain, and the influence of affect in self-care behaviours, this finding has important implications for treatment and management of people with axial SpA.

Reach G. How is Patient Adherence Possible? A Novel Mechanistic Model of Adherence Based on Humanities. Patient Prefer Adherence 2023; 17:1705-1720.

Abstract
Patient non-adherence is a major contemporary medical issue because of its consequences in terms of frequency, morbidity and mortality, and health care costs. This article aims to propose a mechanistic model of adherence based on the tenet that non-adherence is the default option, as long-term adherence in chronic diseases requires sustained effort. The real question becomes, how is patient adherence possible? By focusing on adherent patients, the paper explains the mental mechanisms of adherence using concepts largely drawn from humanities, philosophy of mind, and behavioral economics and presents the findings of empirical studies supporting these hypotheses. The analysis first demonstrates the relationship between patient adherence and temporality and the influence of character traits. Further, it points out the importance of habit, which allows adherence to become non-intentional, thereby sparing patients' cognitive efforts. Finally, it points out the importance of the quality of the interaction between the person with a chronic disease and the health professional. These features explain why adherence is a syndrome (the healthy adherer phenotype), separating people into those who are safe and those who are at risk of non-adherence, non-control of diabetes, and complications. The concepts presented in this article summarize 20 years of personal clinical and philosophical reflection on patient adherence. They are mainly illustrated by examples from diabetes care but can be applied to all chronic diseases. This novel model of adherence has major practical and ethical implications, explaining the importance of patient education and shared medical decision-making in chronic disease management.

Abstract
Introduction Cost-effective interventions that improve medication adherence are urgently needed to address the epidemic of non-communicable diseases (NCDs) in India. However, in low- and middle-income countries like India, there is a lack of analysis evaluating the effectiveness of adherence improving strategies. We conducted the first systematic review evaluating interventions aimed at improving medication adherence for chronic diseases in India. Methods A systematic search on MEDLINE, Web of Science, Scopus, and Google Scholar was conducted. Based on a PRISMA-compliant, pre-defined methodology, randomized control trials were included which: involved subjects with NCDs; were located in India; used any intervention with the aim of improving medication adherence; and measured adherence as a primary or secondary outcome. Results The search strategy yielded 1,552 unique articles of which 22 met inclusion criteria. Interventions assessed by these studies included education-based interventions (n = 12), combinations of education-based interventions with regular follow up (n = 4), and technology-based interventions (n = 2). Non-communicable diseases evaluated commonly were respiratory disease (n = 3), type 2 diabetes (n = 6), cardiovascular disease (n = 8) and depression (n = 2). Conclusions Although the vast majority of primary studies supporting the conclusions were of mixed methodological quality, patient education by CHWs and pharmacists represent promising interventions to improve medication adherence, with further benefits from regular follow-up. There is need for systematic evaluation of these interventions with high quality RCTs and their implementation as part of wider health policy.

Abstract
BACKGROUND: Incorporation of pharmacy fill data into the electronic health record has enabled calculations of medication adherence, as measured by proportion of days covered (PDC), to be displayed to clinicians. Although PDC values help identify patients who may be nonadherent to their medications, it does not provide information on the reasons for medication-taking behaviors. OBJECTIVE: To characterize self-reported adherence status to antihypertensive medications among patients with low refill medication adherence. Our secondary objective was to identify the most common reasons for nonadherence and examine the patient sociodemographic characteristics associated with these barriers. METHODS: Participants were adult patients seen in primary care clinics of a large, urban health system and on antihypertensive therapy with a PDC of less than 80% based on 6-month linked electronic health record-pharmacy fill data. We administered a validated medication adherence screener and a survey assessing reasons for antihypertensive medication nonadherence. We used descriptive statistics to characterize these data and logistic and Poisson regression models to assess the relationship between sociodemographic characteristics and adherence barriers. RESULTS: The survey was completed by 242 patients (57% female; 61.2% White; 79.8% not Latino/a or Hispanic). Of these patients, 45% reported missing doses of their medications in the last 7 days. In addition, 48% endorsed having at least 1 barrier to adherence and 38.4% endorsed 2 or more barriers. The most common barriers were being busy and having difficulty remembering to take medications. Compared with White participants, Black participants (incident rate ratio = 2.49; 95% CI = 1.93-3.22) and participants of other races (incident rate ratio = 2.16; 95% CI = 1.62-2.89) experienced a greater number of barriers. CONCLUSIONS: Nearly half of patients with low PDC reported nonadherence in the prior week, suggesting PDC can be used as a screening tool. Augmenting PDC with brief self-report tools can provide insights into the reasons for nonadherence.

Abstract
This qualitative study interviewed general practitioners, patients, and FLS clinicians and identified key challenges facing stakeholders seeking to improve post-fracture osteoporosis care. Local policies and care pathways as an initial strategy may address information and service delivery issues across the acute-primary care divide. INTRODUCTION Fracture liaison services (FLS) can be effective for secondary fracture prevention, but long-term adherence to therapies remains suboptimal. Few studies have explored how services manage the transition between tertiary and primary post-fracture care. This study mapped service processes and factors influencing integration of post-clinic care, identifying barriers, supports, and opportunities for seamless healthcare. METHODS Qualitative descriptive study using semi-structured interviews with FLS stakeholders at two metropolitan hospitals in New South Wales (NSW) and surrounding general practices. RESULTS Seven FLS clinicians, 11 general practitioners (GPs), and seven patients were interviewed. Six key themes emerged on the transition of patient care from tertiary to primary care (PC). Interprofessional communication issues and role ambiguity posed threats to seamless care. Delayed, absent, inaccessible, or poor-quality communication frustrated GPs, while FLS clinicians lacked confidence in existing communication systems and desired bidirectional communication with PC. GPs were confident managing osteoporosis, but FLS clinicians had limited confidence that patients would discuss osteoporosis with their GP and that GPs would action recommendations. Effective PC follow-up required a positive GP-patient relationship and that patients perceived a need to engage with PC. Patient understanding of osteoporosis (influenced by patient education, knowledge, beliefs, and health behaviours) affected PC attendance. Limited public awareness of osteoporosis and healthcare policy deficits contributed to care gaps. CONCLUSION Key challenges were identified facing stakeholders seeking to improving post-clinic osteoporosis care. Development and implementation of local, integrated acute-community policies and care pathways as an initial intervention may address information and service delivery issues across the acute-PC divide.

Drugs Real World Outcomes 2023:10.1007/s40801-023-00361-7.

Abstract
BACKGROUND Among the determinants of nonadherence, polypharmacy (common in people with multiple pathologies and especially in elderly patients), plays a major role. OBJECTIVE In patients who are subject to polypharmacy involving different classes of medications, the first aim is to assess the impact of medication importance given by patients on (i) medication adherence and (ii) the respective effect of intentionality and habit in medication importance and medication adherence. The second objective is to compare the importance given to medication and adherence in the different therapeutic classes. PATIENTS AND METHODS Patients taking 5-10 different medications for at least 1 month were included in a cross-sectional survey in three private practices in one region in France. RESULTS This study included 130 patients (59.2 % female) with 851 medications in total. The mean ± standard deviation (SD) age was 70.5 ± 12.2 years. The mean ± SD of medications taken was 6.9 ± 1.7. Treatment adherence had a strong positive correlation with the patient-perceived medication importance (p < 0.001). Counter-intuitively, taking a large number of medications (≥7) was associated with being fully adherent (p = 0.02). A high intentional nonadherence score was negatively associated with high medication importance (p = 0.003). Furthermore, patient-perceived medication importance was positively associated with taking treatment by habit (p = 0.03). Overall nonadherence more strongly correlated with unintentional nonadherence (p < 0.001) than with intentional nonadherence (p = 0.02). Compared to the antihypertensive class, a decrease in adherence by medication was observed in psychoanaleptics (p < 0.0001) and drugs used in diabetes class (p = 0.002), and a decrease in importance in lipid-modifying agents class (p = 0.001) and psychoanaleptics (p < 0.0001). CONCLUSION The perception of the importance of a medicine is associated with the place of intentionality and habit in patient adherence. Therefore, explaining the importance of a medicine should become an important part of patient education.

Abstract
Background: Poor medication adherence can lead to adverse health outcomes and increased healthcare costs. Although reasons for medication adherence have been widely studied, less is explored about factors affecting medication adherence for patients in non-Western healthcare setting and from Asian cultures. This study aimed to explore cultural perspectives on factors influencing medication adherence among patients with chronic diseases in a multi-ethnic Asian healthcare setting.Methods: We conducted a qualitative study involving in-depth interviews with patients with chronic conditions purposively recruited from a community hospital in Singapore until data saturation was achieved. A total of 25 patients participated in this study. Interviews were transcribed and thematically analyzed. Themes were subsequently mapped into the World Health Organization (WHO) Framework of Medication Adherence.Results: Participants commonly perceived that sides effects (therapy-related dimension), poor understanding of medication (patient-related dimension), limited knowledge of condition (patient-related dimension), forgetfulness (patient-related dimension) and language issues within a multi-ethnic healthcare context (healthcare team and system-related dimension) as the main factors contributing to medication adherence. Importantly, medication adherence was influenced by cultural beliefs such as the notion of modern medicines as harms and fatalistic orientations towards escalation of doses and polypharmacy (patient-related dimension). Participants made various suggestions to foster adherence, including improved patient-physician communication, enhanced care coordination across providers, use of language familiar to patients, patient education and empowerment on the benefits of medication and medication adjustment.Conclusion: A wide range of factors influenced medication adherence, with therapy- and patient-related dimensions more pronounced compared to other dimensions. Findings demonstrated the importance of cultural beliefs that may influence medication adherence. Future efforts to improve medication adherence should consider a person-centered approach to foster more positive health expectations and self-efficacy on medication adherence, supplemented with routine reviews, development of pictograms and cultural competence training for healthcare professionals.

Abstract
BACKGROUND Medication adherence impacts health outcomes. Healthcare organisations implementing system-level interventions have potential for greater spread and sustainability than individual-level interventions. Within the integrated US Veterans Health Administration, a multidisciplinary team developed and evaluated a pilot quality improvement programme to assess the feasibility of automatic mailed prescription refills for patients with diabetes and low medication adherence (assessed by medication possession ratio <80%). METHODS Patients were randomised to usual care with self-initiated refills versus automatic mailed refills for 6 months. Process outcomes included glycaemic control measures (HgbA1C), medication possession ratios for both automatic and self-initiated (reference) refills of medications, patient satisfaction and workforce effort (pharmacist time). RESULTS Overall, 199 patients were randomised to automatic refills (n=99; 40 of whom participated) versus usual care (n=100). In multivariable analysis adjusting for baseline differences, after 6 months there was no difference in the proportion of patients with follow-up HgbA1C <8% (60.8% automatic refills vs 60.5% usual care, p=0.96). In the automatic refill group, the medication possession ratio for reference medicines was significantly higher than usual care (63.9% vs 54.5%, 95% CI (for difference) 3.1% to 15.9%, p<0.01). CONCLUSIONS Implications and lessons from this pilot programme include potential beneficial indirect effects from automatic medication refills on patient self-initiated refills of other medications; the importance of tailoring solutions to patient subgroups and specific adherence barriers; and recognition that the rapid deployment, iteration and evaluation of the project was facilitated by a multidisciplinary team embedded within an organisational learning health system.

Abstract
PURPOSE Before the COVID-19 pandemic and the disruptions it brought, medication adherence was already a challenging and complex health behavior. The purpose of this study was to describe patients' interactions in clinic, pharmacy, and home contexts and associated medication management and adherence during the early phase of the COVID-19 pandemic. PATIENTS AND METHODS A survey questionnaire was developed using the Medication Adherence Context and Outcomes framework and distributed via social media between May and July 2020 targeting adults taking a daily prescribed medication. Survey questions assessed sociodemographics, interactions with healthcare providers, clinics, pharmacies, medication management experiences, habit strength, and life chaos perceptions during the pandemic. Medication adherence was assessed by the self-report BAASIS© scale to measure implementation, discontinuation, and overall nonadherence. RESULTS A total of 134 adults from the United States, mean age 50.0 (SD 16.1) years were included in this analysis. Respondents took a median of 3.50 (interquartile range 4) daily medications. Delays in seeing a provider were reported by 47 (35.1%). Pharmacy encounters were impacted; 25 (18.7%) indicated their method for obtaining medication changed. Medication nonadherence was reported among 62 (46.3%) and was significantly greater among those who delayed prescription refills (p=0.032), pillbox users (p=0.047), and those who experienced greater life chaos (p=0.040) and lower habit strength (p<0.001) in the early phase of the pandemic. CONCLUSION Although the early phase of the pandemic affected access to care for nearly one-third of the sample, distance-accessible care options and strategies to obtain needed services without being in-person supported respondents medication management. Helpful strategies included provider accessibility, telehealth, home delivery/mail-order, drive-thru's, 90-day supplies, and online/automatic refills. Methods to develop and reestablish habits are critical. Care providers in clinic and pharmacy settings can educate and remind patients about services like distance-accessible technologies and online ordering of medications and establishing routines to support medication adherence.

Abstract
Few studies have examined the independent effects of different manifestations of HIV stigma experiences on health outcomes among youth living with HIV in low- and middle-income countries. We examined the association of internalized, enacted, and perceived HIV stigmas with medication adherence, self-esteem, depression, and barriers to adherence. Young people living with HIV aged 18-21 years (N = 120) were purposively sampled from two health facilities in Eastern Province, Zambia, and completed self-report measures. Results indicated heterogeneous associations. Internalized HIV stigma was positively associated with depression and negatively associated with adherence, adherence motivation, behavioral adherence skills, and self-esteem. Perceived stigma was negatively associated with self-esteem. No significant association was observed between enacted stigma and health outcomes. The complexity of HIV stigma requires a precise explication of the associations among different HIV stigma experiences and outcomes, which can inform the development of stigma reduction interventions targeting one or more stigma experiences.

Badge H, Churches T, Naylor JM, Xuan W, Armstrong E, Gray L, Fletcher J, Gosbell I, Christine Lin CW, Harris IA. Association between VTE and antibiotic prophylaxis guideline compliance and patient-reported outcomes after total hip and knee arthroplasty: an observational study. J Patient Rep Outcomes 2022; 6:110. [PMID: 36224453 PMCID: PMC9556685 DOI: 10.1186/s41687-022-00502-6] [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: 03/23/2022] [Accepted: 09/02/2022] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND Surgical site infection (SSI) and venous thromboembolism (VTE) are associated with high burden and cost and are considered largely preventable following total knee or hip arthroplasty (TKA, THA). The risk of developing VTE and SSI is reduced when prophylaxis is compliant with evidence-based clinical guidelines. However, the association between VTE and antibiotic prophylaxis clinical guideline compliance and patient-reported outcome measures (PROMs) after THA/TKA is unknown. This study aims to explore whether care that is non-compliant with VTE and antibiotic guideline recommendations is associated with PROMs (Oxford Hip/Knee Score and EQ-5D Index scores) at 90- and 365-days after surgery. METHODS This prospective observational study included high-volume arthroplasty public and private sites and consenting eligible participants undergoing elective primary THA/TKA. We conducted multiple linear regression and linear mixed-effects modelling to explore the associations between non-compliance with VTE and antibiotic guidelines, and PROMs. RESULTS The sample included 1838 participants. Compliance with VTE and antibiotic guidelines was 35% and 13.2% respectively. In adjusted modelling, non-compliance with VTE guidelines was not associated with 90-day Oxford score (β = - 0.54, standard error [SE] = 0.34, p = 0.112) but was significantly associated with lower (worse) 365-day Oxford score (β = - 0.76, SE = 0.29, p = 0.009), lower EQ-5D Index scores at 90- (β = - 0.02 SE = 0.008, p = 0.011) and 365-days (β = - 0.03, SE = 0.008, p = 0.002).. The changes in Oxford and EQ-5D Index scores were not clinically important. Noncompliance with antibiotic guidelines was not associated with either PROM at 90- (Oxford: β = - 0.45, standard error [SE] = 0.47, p = 0.341; EQ-5D: β = - 0.001, SE = 0.011, p = 0.891) or 365-days (Oxford score: β = - 0.06, SE = 0.41, p = 0.880 EQ-5D: β = - 0.010, SE = 0.012, p = 0.383). Results were consistent when complications were included in the model and in linear mixed-effects modelling with the insurance sector as a random effect. CONCLUSIONS Non-compliance with VTE prophylaxis guidelines, but not antibiotic guidelines, is associated with statistically significant but not clinically meaningful differences in Oxford scores and EQ-5D Index scores at 365 days.

Abstract
INTRODUCTION Adherence to adjuvant therapy is crucial for effective disease management in patients with resected melanoma. This study assessed patient-reported adherence to adjuvant therapy and identified behavioral/belief constructs associated with adherence in patients with resected melanoma. METHODS Patients with resected stage III/IV melanoma were recruited through the Melanoma Research Foundation and a patient panel to complete an online survey. Patient characteristics, medical history, and adherence to therapy were captured. In accordance with the theory of planned behavior (TPB), the survey measured behavioral, normative, and control beliefs, and intention to adhere to therapy. Structural equation modeling (SEM) examined their relationships with adherence. RESULTS Among all patients who received adjuvant therapy and completed the survey (n = 184), 69% received intravenous and 31% received oral therapy; the majority (85.3%) were somewhat involved in deciding to start therapy. Mean age was 45 years, 44% of patients were female, and 83% had stage III/IV disease at diagnosis. Patients had a mean disease duration of 1.5 years, a time since complete resection of 10 months, and an adjuvant therapy duration of 8 months. Adherence to adjuvant therapy was high overall and higher with intravenous than with oral therapy (98.4% versus 91.2%, P = 0.002). All underlying TPB constructs were significant in the SEM model, which explained 60.3% of the variance in intention to adhere. Control beliefs had the strongest association with intention to adhere (standardized estimate = 0.47, P < 0.001) and intravenous therapy was associated with greater adherence than oral therapy (standardized estimate = 0.26, P < 0.001). CONCLUSIONS This study found that patients with resected melanoma are highly engaged in the decision to initiate systemic adjuvant therapy, with an overall high adherence rate to prescribed adjuvant treatment. Enhancing patients' view of their capability to adhere to treatments may further improve the adherence rate to melanoma adjuvant therapy.

Abstract
Introduction Disparities in the care and outcomes of peripheral artery disease (PAD) have been well-established. In part this is due to disparities in enrollment of PAD trial cohorts. However, less attention has been paid to non-random protocol non-adherence after enrollment, which may lead to inaccurate estimates of treatment effects and reduce generalizability of study results. We aimed to ascertain characteristics associated with premature study drug discontinuation in a PAD cohort. Methods Using data from EUCLID (Examining Use of Ticagrelor in Peripheral Artery Disease), factors associated with study drug discontinuation were assessed using univariable and multivariable Cox proportional hazards models with time to study drug discontinuation as the outcome of interest. Relationships between study drug discontinuation and major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, ischemic stroke), major adverse limb events (MALE; acute limb ischemia, major amputation, and lower extremity revascularization), and all-cause hospitalization were assessed. Results Of 13,842 eligible EUCLID participants, 3,886 (28.1%) prematurely and permanently discontinued study drug over a maximum follow-up of 42 months (annualized rate of 13.2 discontinuations per 100 patient-years). In a multivariable model, premature study drug discontinuation was associated with older age (aHR 1.16, 95%CI 1.14–1.19), eligibility based on prior lower extremity revascularization rather than ABI/TBI criteria (aHR 1.14, 95%CI 1.06–1.23), CLI status (aHR 1.23, 95%CI 1.06–1.42), COPD (aHR 1.36, 95%CI 1.24–1.49), and geographic region. In a multivariable analysis, study drug discontinuation was significantly associated with MACE (aHR 3.27, 95%CI 2.90–3.67, p < 0.001), MALE (aHR 1.84, 95%CI 1.63–2.07, p < 0.001), and all-cause hospitalization (aHR 2.37, 95%CI 2.21–2.54) following study drug discontinuation. Conclusions This analysis of EUCLID demonstrates that premature, permanent discontinuation of study drug is relatively common in more than a quarter of PAD patients, is unevenly distributed based on geography and other baseline characteristics, and is associated with worse outcomes in a clinical trial context. Study teams leading future PAD trials may want to address the possibility of study drug discontinuation prospectively, as a proactive approach may help investigators to maintain study cohort diversity and representativeness without sacrificing power and precision.

Exploring a New Theoretical Model to Explain the Behavior of Medication Adherence. PHARMACY 2022; 10:pharmacy10020043.

Abstract
Medication adherence is essential for optimal therapeutic outcomes. However, non-adherence with long-term therapy is at 50%. Several theoretical models have identified several key factors that could explain medication adherence. Though numerous interventions have been developed based on these theoretical models, the success rates with interventions are not the best. This paper proposes a new Hierarchical Model for Medication Adherence. In this model, we propose medication adherence as a five-tier model with medication adherence as the desirable behavior on the top of the pyramid. From the bottom of the hierarchy upwards, the skills/beliefs/behaviors to be achieved are: health literacy, belief in illness (impacted by perceived susceptibility and severity of illness), belief in medicines (impacted by treatment satisfaction), and self-efficacy (impacted by social support). The model further proposes that each individual will achieve or already have these skills/beliefs/behaviors at various levels. Screening patients for these benchmarks will enable providers to decide where to target interventions.

Abstract
Background Disease-modifying anti-rheumatic drugs (DMARDs) are the cornerstone of rheumatoid arthritis (RA) treatment. However, the full benefits of DMARDs are often not realized because many patients are sub-optimally adherent to their medication. In order to optimize adherence, it is essential that healthcare professionals (HCPs) understand patients’ barriers and facilitators for medication use. Insight in these barriers and facilitators may foster the dialogue about adequate medication use between HCPs and patients. What HCPs perceive as barriers and facilitators has, so far, scarcely been investigated. This study aimed to identify the perceptions of HCPs on patients’ barriers and facilitators that might influence their adherence. Methods This qualitative study was performed using semi structured in-depth interviews with HCPs. An interview guide was used, based on an adjusted version of the Theoretical Domains Framework (TDF). Thematic analysis was conducted to identify factors that influence barriers and facilitators to DMARD use according to HCPs. Results Fifteen HCPs (5 rheumatologists, 5 nurses and 5 pharmacists) were interviewed. They mentioned a variety of factors that, according to their perceptions, influence DMARD adherence in patients with RA. Besides therapy-related factors, such as (onset of) medication effectiveness and side-effects, most variation was found within patient-related factors and reflected patients’ beliefs, ways of coping, and (self-management) skills toward medication and their condition. In addition, factors related to the condition (e.g., level of disease activity), healthcare team and system (e.g., trust in HCP), and social and economic context (e.g. support, work shifts) were reported. Conclusions This study provided insights in HCPs’ perceptions of the barriers and facilitators to DMARD use patients with RA. Most factors that were mentioned were patient-related and potentially modifiable. When physicians understand patients’ perceptions on medication use, adherence to DMARDs can probably be optimized in patients with RA leading to more effectiveness of treatment outcomes.

Assessment of medication adherence, medication safety awareness and medication practice among patients with lung cancer: A multicentre cross-sectional study. Health Expect 2022; 25:791-801.

Abstract
OBJECTIVES We aimed to explore the current status of medication adherence, safety awareness and practice among patients with lung cancer. METHODS We conducted a questionnaire-guided cross-sectional study in Xi'an, Yulin, Hanzhong and Weinan in Shaanxi Province, China, from April to June 2021 for a period of 3 months. The study questionnaire was developed according to previous related studies reported in the literature, and includes basic demographic information and patients' medication safety questions. The data were double-entered using EpiData 3.1 software; descriptive statistics, t-test, analysis of variance, the Kruskal-Wallis test and the Mann-Whitney U-test were performed to analyse the data. RESULTS A total of 567 participants were included, and 409 valid questionnaires were finally completed, with an effective response rate of 72.13%. More than 80% of patients showed good medication adherence; the average adherence score was 22 ± 2.68 of 25. The average score for medication safety awareness was 16.40 ± 4.41, which was significantly lower than that of medication adherence (p < .001). Only 22.74% of patients always checked their medicines before a nurse administered them; 17.60% of patients never checked their medicines. Few patients actively consulted an health care professional to understand safety information before taking a medication. A significant difference existed in safety awareness scores among age groups (p = .039) and geographic regions (p < .001). Patients with three or more comorbidities had the lowest awareness scores (p = .027). CONCLUSION We found that patients with lung cancer showed better medication adherence, but their awareness about medication safety was poor. Older patients, those with comorbidities and patients in regions with poor medical resources may have worse awareness about safety. Current medication education for patients should not only aim to improve adherence but should also encourage patients to take greater responsibility for their own safety and to actively participate in their medication safety. Greater systematic and individualized medication safety information is needed for older patients, those with more comorbidities and patients in areas with poor medical resources. PATIENT CONTRIBUTION We conducted a questionnaire-guided cross-sectional study on hospitalized lung cancer patients in Shaanxi Province to explore the patients' practices related to safety medication, including medication adherence and medication safety awareness.

Abstract
Experienced drug-handling problems and inadequately considered expectations for drug therapy have an unfavorable influence on therapy. We performed a questionnaire survey in (i) parents of 0-5-year-old children and (ii) 6-17-year olds and their parents. We assessed (A) experienced drug-handling problems and (B) expectations for drug therapy. (i) Forty-six parents and (ii) 103 children and their parents participated in the study. Experienced drug-handling problems were described by (i) 100% of parents and (ii) 62% of children and 70% of parents. Problems concerned with the preparation of the drug, dosing, compliance with the time interval, and acceptance. (i) Sixty-five percent of parents preferred a peroral route of drug administration, while (ii) 74% of children and 86% of parents did so. Preferred characteristics of peroral drug formulations, e.g., liquid versus solid drug formulations or flavor, were highly heterogeneous. Preferences of 6-17-year-old children and their parents matched in 43 to 66%. Conclusion: Most children and their parents had already experienced drug-handling problems. Preferences concerning the ideal pediatric drug were highly heterogeneous and in about half of cases, preferences of children and their parents differed. Thus, the children should be approached directly. If information is solely gained from parents, the children's needs might remain unmet. What is Known: • Pediatric drug administration is complex and therefore error-prone. • Experiences and expectations of children and their parents should be considered. What is New: •Most pediatric patients and their parents have already experienced drug-handling problems. • Expectations concerning the ideal pediatric drug are highly heterogeneous. Parents are often insufficiently aware of those expectations in their children.

Abstract
BACKGROUND A variety of factors influenced the decision of tuberculosis (TB) drug-resistant patients to continue treatment. The study aimed to analyze factors that influence complying with anti-TB medications in patients with TB drug resistance in Indonesia. PATIENTS AND METHODS The study employed a cross-sectional approach and was conducted in various community health centers and polyclinics offering TB drug-resistant services in Bandung city, Indonesia. Participants were 79 patients with TB drug resistance who met the criteria during their treatment for TB drug resistance, were willing to be involved in the research, and accessed TB services in Bandung. Complying with anti-TB medications scale, TB Health Behaviors questionnaire, the family support questionnaire, the TB-Related Stigma Scale, and TB knowledge were used in this study. Data were analyzed using Spearman's Rho. RESULTS Health behavior (r = 0.36) was positively associated with complying with anti-TB medications, while family support, TB stigma, and knowledge were not related to treatment compliance. CONCLUSION Information on these factors will inform the development of models and modules for the prevention and control of TB drug resistance in Indonesia, which can later be used widely in Indonesia.

Shiyanbola OO, Maurer MA, Virrueta N, Walbrandt Pigarelli DL, Huang YM, Unni EJ, Smith PD. Feasibility of a Randomized Controlled Mixed Methods Trial to Address Health Literacy, Beliefs, Medication Adherence, and Self-Efficacy (ADHERE) in a Clinical Pharmacist-Led Clinic. Patient Prefer Adherence 2022; 16:679-696. [PMID: 35300357 PMCID: PMC8922467 DOI: 10.2147/ppa.s349258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 02/12/2022] [Indexed: 11/29/2022] Open
Abstract
PURPOSE To assess the feasibility and acceptability of a health literacy-psychosocial support intervention - ADHERE and explore changes in glycemic values and medication adherence. PATIENTS AND METHODS Thirty-one participants with hemoglobin A1c (HbA1c) ≥ 8% were randomly allocated to control (usual care) or intervention groups (receiving usual care plus a 6-session pharmacist-led intervention focusing on the modifiable psychosocial factors that may influence medication adherence). Feasibility metrics evaluated recruitment, retention, and intervention adherence. Questionnaires were administered to collect psychosocial factors and self-reported medication adherence at baseline, the end of the intervention, 3 months, and 6 months post intervention. HbA1c values were extracted from electronic medical records. Repeated measures analysis of variance was used to compare differences in mean outcomes between the control and intervention groups. To assess intervention acceptability, eleven individuals participated in semi-structured interviews about their intervention experiences. Qualitative content analysis was used for analyzing the interviews. RESULTS Thirty participants completed the study. Overall, the findings support the feasibility of the intervention. There were significant differences in HbA1c values. Participants in the intervention group had lower A1C (8.3 ± 1.4) than in the control group (9.2 ± 1.3) at the time of 6-month follow-up (p = 0.003). In addition, the participants in the intervention group showed improved HbA1c at 6-month follow-up (8.3 ± 1.4), compared to baseline (9.4 ± 1.5, p = 0.011) and after 6-session intervention (8.9 ± 1.6, p = 0.046). However, there were no significant differences in medication adherence between groups over time. Qualitative themes suggest participants liked the intervention and perceived the additional support from the pharmacist as beneficial. CONCLUSION A pharmacist-led intervention to provide additional health literacy-psychosocial support may contribute to long-term improvements in HbA1c. Equipping pharmacists with patient-specific diabetes medication adherence information and building in additional follow-up support for patients may improve patient health outcomes.

Abstract
OBJECTIVES To investigate the knowledge, attitudes, and barriers related to medication adherence in older patients with coronary heart disease (CHD). METHODS A total of 272 older patients with CHD were investigated by the Chinese version of the Medication Adherence Scale. The score ranges for the knowledge, attitudes, and barrier subscales were 0-30, 0-30, and 0-110, respectively. Higher scores indicate more knowledge, positive attitudes, and more barriers related to medication adherence. RESULTS The median scores of knowledge, attitudes and barriers were 25.5, 28, and 8, respectively. Having stents, living alone, good financial status and fewer chronic diseases were related to more knowledge. Younger age, having no stent, and more chronic diseases were associated with more barriers. Patients with good financial status and higher age had more positive attitudes. CONCLUSIONS Understanding older patients' knowledge, attitudes, and barriers related to medication adherence and their associated factors can help develop tailored interventions in medication adherence studies.

Results from an online survey of 3,001 patients with cardio-metabolic pathologies in France. Patient Prefer Adherence 2021; 15:1739-1753. [PMID: 34408407 PMCID: PMC8366034 DOI: 10.2147/ppa.s318116] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Accepted: 07/21/2021] [Indexed: 11/23/2022] Open
Abstract
PURPOSE Some patients make a rational choice not to follow medical prescriptions; others fail to take their medications for reasons beyond their control, such as mere forgetfulness or a weak medication routine. The aim of this study was to elucidate the functioning of patient intentionality in medication adherence. PATIENTS AND METHODS This online study was conducted in metropolitan France in 2019. A cross-sectional survey of 50 questions was conducted with 3001 respondents diagnosed with diabetes, hypertension, and/or hypercholesterolemia identified from a panel of 54,000 people. These questions included a validated six-item questionnaire to detect nonadherence, two questions to detect intentional nonadherence by patients, and three questions on the effects of habit. Our questionnaire also included questions on the feelings of respondents regarding their doctor's attitude to their problems and needs, their trust in general practitioners (GP) and specialists, their sense of being involved in treatment decisions, and the influence of side effects and habits on patients' adherence. This study used the strategy of focusing on strictly adherent patients in the hope of finding ways to improve adherence. For this reason, we defined adherence as the absence of a positive response to the 6-item nonadherence screening questionnaire. RESULTS Of 3001 respondents, 1804 were diagnosed with hypertension, 1458 with hypercholesterolemia, and 774 with diabetes. Of the total number of patients, 72% were afflicted with one disease, 21% with two ailments, and 7% with three simultaneous illnesses. One-third (33%) of the patients did not tender a positive answer to the adherence questionnaire and were deemed adherent. 1) Thirty-two percent of the patients reported occasionally omitting their medication deliberately, and 84% said they had a reason for missing doses. These statements suggesting intentional nonadherence were negatively associated with adherence as identified via multivariate analysis (P = 0.0012 and P < 0.0001, for the first and second statement, respectively). 2) Univariate analyses revealed strong associations (P < 0.0001) between strict adherence on one hand and lack of intentional nonadherence, patient age, absence of drug side effects, taking drugs by habit, feeling involved in treatment decisions, getting information about treatment, and disease, and trust in doctors, on the other hand. 3) Specifically, univariate analysis of the absence of reported side effects revealed strong associations (P < 0.0001) with adequate information about medicines and diseases and trust in GP. These original data were consistent with the concept of the nocebo effect. 4) We observed a strong association between the absence of intentional nonadherence (statement of never deliberately missing medication) and respondent statements about generally sticking to the routine (P < 0.0001), ie, "I take my medication because I am used to taking it." This important result suggests that patients are strictly adherent in two ways: the absence of intentional nonadherence and reliance on habit, which we term as "unintentional adherence." 5) Finally, a multiple correspondence analysis illustrated all statistically significant relationships found in this study. CONCLUSION We present a new global model of adherence in which patient adherence was improved both by reducing intentional nonadherence and by promoting the abovementioned unintentional adherence by habit. This model highlights the role of shared decision-making and the trust felt by patients in their doctors. These results could exert a major impact on medical practice and education by demonstrating the importance of physicians' attitudes, involving the patient in decisions (shared decision-making), offering information about medicines and diseases (patient education), understanding the problems of patients, and taking their needs into account (empathy). The development of these attitudes should be an important aspect of the medical curricula.
