Educational Needs and Priorities of People with Diabetes and Healthcare Providers in South Korea: A Mixed-Methods Study.

Introduction: Effective self-care for managing diabetes requires culturally sensitive and patient-centered education. This study explored the educational needs and priorities of people with diabetes (PWD) and healthcare providers (HCPs). Method: A mixed-methods approach was employed with participants from a university-affiliated hospital in South Korea. Descriptive and content analyses were used for the questionnaire and interview data. Results: Both PWD (n=33) and HCPs (n=42) ranked diabetes-related side-effect management and medication purpose as the most important aspects of diabetes education. PWD had higher educational needs regarding diagnosed diseases and lifestyle modifications than HCPs. Three themes were revealed: incorporating lifestyle changes and medication taking, collaborating with HCPs and caregivers and providing care to meet person-centered mental health needs, and enhancing education on disease and complications. Discussion: Culturally sensitive and patient-centered education programs that recognize communal values, reflect individual preferences and needs, and promote lifestyle changes by leveraging technologies for Korean PWD are crucial.

Concurrent factors associated with adherence to adjuvant endocrine therapy among women with non-metastatic breast cancer.

PURPOSE: Adjuvant endocrine therapy (AET) reduces breast cancer morbidity and mortality, yet women often report suboptimal adherence. Though correlates of AET adherence are well-documented, few studies examine the relative importance of multi-level factors associated with adherence. The aim of this study was to identify factors most strongly associated with AET adherence in women with breast cancer. METHODS: Between 10/2019 and 6/2021, women (N = 100) with non-metastatic, hormone receptor-positive breast cancer, taking AET who reported AET-related distress enrolled into a clinical trial. Participants completed baseline measures, including the Medication Adherence Rating Scale-5, sociodemographics, and validated measures of anxiety, depression, medication-taking self-efficacy, social support, and treatment satisfaction. We created a latent factor and tested associations between sociodemographic, medical, and psychosocial characteristics and adherence. Associated predictors (p < .10) were entered into a structural model, which was corroborated via multivariate regression modeling. RESULTS: A four-indicator latent adherence factor demonstrated good model fit. Participants (Mage = 56.1 years, 91% White) who were unemployed (B = 0.27, SE = 0.13, p = .046) and reported greater treatment convenience (B = 0.01, SE = 0.01, p = .046) reported greater adherence. Scores of participants who reported greater medication-taking self-efficacy (p = .097) and social support (p = .062) approached better adherence. Greater medication-taking self-efficacy (B = 0.08, SE = 0.02, p < .001) and being unemployed (B = 0.28, SE = .14, p = .042) were most strongly associated with greater adherence, independent of other predictors. Multivariate modeling confirmed similar findings. CONCLUSIONS: Medication-taking self-efficacy and employment status were associated with AET adherence above other related factors. IMPLICATIONS FOR CANCER SURVIVORS: Enhancing patients' confidence in their ability to take AET for breast cancer may represent an important intervention target to boost adherence.

How Pharmacogenomics Informs and Influences the Medication Experience.

Both pharmacogenomics (PGx) and the medication experience (MedXp) share a common purpose for their use, which is to optimally tailor medications to each unique individual. The former pursues this aim by using an individual's genetic makeup, while the latter considers the subjective experience of medication-taking in one's life. The different ways by which these fields of study pursue their shared aim have resulted in relatively little understanding of their relationship when utilized in care processes to produce health outcomes. This commentary explores this gap and identifies implications for future research that can help close it to improve person-centered care.

A Participatory Sensing Study to Understand the Problems Older Adults Faced in Developing Medication-Taking Habits.

Past research has demonstrated that older adults tend to use daily activities as cues to remember to take medications. However, they may still experience medication non-adherence because they did not select adequate contextual cues or face situations that interfere with their medication routines. This work addresses two research questions: (1) How does the association that older adults establish between their daily routines and their medication taking enable them to perform it consistently? (2) What problems do they face in associating daily routines with medication taking? For 30 days, using a mixed-methods approach, we collected quantitative and qualitative data from four participants aged 70-73 years old about their medication taking. We confirm that older adults who matched their medication regimens to their habitual routines obtained better results on time-based consistency measures. The main constraints for using daily routines as contextual cues were the insertion of medication taking into broad daily routines, the association of multiple daily routines with medication taking, the lack of strict daily routines, and the disruption of daily routines. We argue that the strategies proposed by the literature for forming medication-taking habits should support their formulation by measuring patients' dosage patterns and generating logs of their daily activities.

Navigating medication-taking after kidney transplant.

BACKGROUND: Mixed methods are valuable in understanding multifaceted health behaviors like medication adherence. Kidney transplant recipients (KTRs) have complex medication regimens and are more vulnerable to nonadherence relative to other transplant recipients. Yet mixed methods have not been widely applied to examine adherence among KTRs, especially in relation to prescribed medications beyond immunosuppressants. OBJECTIVES: As part of a sequential approach, we used in-depth interviews to better understand findings from a previous quantitative study and to describe additional factors that influence prescription medication-taking among adult KTRs. METHODS: Semi-structured interviews were conducted with a purposive sample of 14 adult KTRs recruited from a transplant center in Chicago, IL. Deductive and inductive content analysis was used to code transcripts and identify key themes. RESULTS: Across the sample, we identified insurance challenges, disruptions in routine, and poor mental well-being as barriers to adherence at the patient level. For Black and Hispanic KTRs, poor communication between providers and disjointed care transitions posed additional barriers at the health system level. Compared with White KTRs, Black and Hispanic KTRs experienced greater medication burden due to comorbidities, while medication and digital literacy challenges were unique to Hispanic KTRs. CONCLUSION: KTRs are often motivated to take medications as prescribed, but sometimes lack the capacity or support to do so. Eliciting KTR perspectives is necessary in addressing knowledge and resource gaps at the patient and health system levels to improve adherence. In addition, recognizing the relative burden of taking comorbidity medications compared with immunosuppressants may important, particularly for Black and Hispanic KTRs.

'For me, it didn't seem as drastic a step as being controlled by insulin': A qualitative investigation of expectations and experiences of non-insulin injectable therapy among adults with type 2 diabetes.

AIMS: This qualitative study aims to explore beliefs, attitudes and experiences of injectable glucagon-like-peptide-1 receptor agonists (GLP-1RAs) use and discontinuation, as well as attitudes to further injectable treatment intensification, among adults with type 2 diabetes (T2D). METHODS: Nineteen in-depth semi-structured interviews lasting (mean ± standard deviation) 45 ± 18 min were conducted, face-to-face (n = 14) or via telephone (n = 5). Transcripts were analysed using inductive template analyses. Eligible participants were English-speaking adults with T2D who had recently initiated (≤3 years) GLP-1RA treatment. RESULTS: Participants were aged 28-72 years, who predominantly lived in metropolitan areas (n = 15), and had an experience of daily (n = 11) and/or once-weekly (n = 13) GLP-1RA formulations. Six participants had discontinued treatment and seven had trialled two or more formulations. Expectations and experiences of GLP-1RA were related to the perceived: (1) symbolism and stigma of injectable diabetes treatment; (2) ease of injectable administration and device preferences; (3) treatment convenience and social impact; (4) treatment efficacy and benefits, and; (5) negative treatment side effects. Some participants reported increased receptiveness to insulin therapy following their GLP-1RA experience, others emphasised unique concerns about insulin beyond injectable administration. CONCLUSIONS: This study provides a novel understanding of expectations and experience of non-insulin injectables among Australian adults with T2D. Our data suggest expectations may be informed by attitudes to insulin therapy, while perceived treatment benefits (e.g. weight-related benefits, administration frequency) may motivate uptake and ongoing use despite concerns. Experience of GLP-1RA injections may impact receptiveness to future insulin use.

Relational dynamics involved in therapeutic discordance among prescribers and patients: A Grounded Theory study.

OBJECTIVE: No studies have explored the negative process of concordance: discordance in prescribing-medication-taking. This study provides a deeper understanding of discordance as a co-constructed process among patients and prescribers. METHODS: To explore the question "what psychological and relational processes are involved when therapeutic discordance among prescribers and receivers occurs?" a constructivist Grounded Theory study was carried out through semi-structured interviews with patients and their medical doctors. RESULTS: The final sample of our study was composed of 29 participants: 16 receivers and 13 prescribers. "Neglecting the relationship", the core category, shapes the therapeutic discordance and connects three main conceptual phases: signing a non-negotiating contract, acting alone, and establishing a superficial relationship. CONCLUSION: Our grounded theory conceptualization contributes to the concordance-related debate by evidencing the processes among prescribers and receivers in interwoven actions. It offers another dimension to how notions of compliance, adherence and concordance have been theorized to date. PRACTICE IMPLICATIONS: More than one interaction with receivers is recommended. If there are hints that conflict potentially is compromising the relationship, prescribers should involve intermediaries. Setting aside for a moment, evidence-based justification for treatments and trying to understand prescribers' motivations may boost a positive change.

Using data mining technology to predict medication-taking behaviour in women with breast cancer: A retrospective study.

AIMS: Medication-taking behaviours of breast cancer survivors undergoing adjuvant hormone therapy have received considerable attention. This study aimed to determine factors affecting medication-taking behaviours in people with breast cancer using data mining. DESIGN: A longitudinal observational retrospective cohort study with a hospital-based survey. METHODS: A total of 385 subjects were surveyed, analysing existing data from January 2010 to December 2017 in Taiwan. Three data mining approaches-multiple logistic regression, decision tree and artificial neural network-were used to build the prediction models and rank the importance of influencing factors. Accuracy, specificity and sensitivity were used as assessment indicators for the prediction models. RESULTS: Multiple logistic regression was the most effective approach, achieving an accuracy of 96.37%, specificity of 96.75% and sensitivity of 96.12%. The duration of adjuvant hormone therapy discontinuation, duration of adjuvant hormone therapy use and age at diagnosis by data mining were the three most critical factors influencing the medication-taking behaviours of people with breast cancer.

Spinal cord injury/dysfunction and medication management: a qualitative study exploring the experiences of community-dwelling adults in Ontario, Canada.

PURPOSE: To explore the attitudes, beliefs and experiences pertaining to the management of prescribed and unprescribed medications among community-dwelling adults with spinal cord injury/dysfunction (SCI/D) in Ontario, Canada. MATERIALS AND METHODS: In-depth semi-structured interviews were conducted by telephone. Each interview was audio-recorded, transcribed verbatim and analyzed using inductive thematic analysis. RESULTS: Of the 19 participants, 11 were male and 8 were female, with an age range from 36 to 76 years; 14 participants had traumatic SCI and 5 had non-traumatic spinal cord dysfunction. All but three participants were taking five or more medications, including prescription medications, over-the-counter medications and natural health products. The three main themes identified were: disruptive nature of medications, fear of negative outcomes and self-management: playing a critical role. CONCLUSIONS: Medication management is a complex, multifaceted and non-linear process. Persons with SCI/D described experiences with medication-taking that are not well understood by current medication management frameworks. Thus, it is essential to broaden our lens and situate persons with SCI/D medication-taking experiences within self-management frameworks to allow for a more comprehensive and reflective understanding of their experiences. Based on the findings from this study, recommendations for future research, practice and policy have been suggested.IMPLICATIONS FOR REHABILITATIONPersons with spinal cord injury/dysfunction identified numerous challenges and concerns with medication use post-injury.Educational medication management programs should be implemented post-discharge to improve the state of knowledge around medications (indication, side effects, strategies for taking medications) and how to optimize medication management.In order to optimize experiences and outcomes, there is a need for explicit and ongoing discussions around medication management between persons with spinal cord injury/dysfunction and their healthcare providers.

A Qualitative Study on Medication Taking Behaviour Among People With Diabetes in Australia.

Background: Australia has a high proportion of migrants with an increasing migration rate from India. Type II diabetes is a long-term condition common amongst the Indian population. Aims: To investigate patients' medication-taking behaviour and factors that influence adherence at the three phases of adherence. Methods: Semi-structured interviews were conducted with a convenience sample of 23 Indian migrants living in Sydney. All interviews were audio-recorded, transcribed verbatim and thematically analysed. Results: 1) Initiation: The majority of participants were initially prescribed oral antidiabetic medicine and only two were started on insulin. Most started taking their medicine immediately while some delayed initiating therapy due to fear of side-effects. 2) Implementation: Most participants reported taking their medicine as prescribed. However, some reported forgetting their medicine especially when they were in a hurry for work or were out for social events. 3) Discontinuation: A few participants discontinued taking their medicine. Those who discontinued did so to try Ayurvedic medicine. Their trial continued for a few weeks to a few years. Those who did not receive expected results from the Ayurvedic medicine restarted their prescribed conventional medicine. Conclusion: A range of medication-taking behaviours were observed, ranging from delays in initiation to long-term discontinuation, and swapping of prescribed medicine with Ayurvedic medicine. This study highlights the need for tailored interventions, including education, that focus on factors that impact medication adherence from initiation to discontinuation of therapy.

Patient-physician interpersonal processes of care at the time of diabetes treatment intensification and their links to patient outcomes.

OBJECTIVE: To investigate how patient-physician interpersonal processes of care are related to levels of diabetes-related distress, diabetes medication-taking behavior, and HbA1c during conversations with patients about intensifying medication. METHODS: We randomly recruited 1270 patients from diabetes specialty clinics in Tehran, Iran who were taking an additional oral diabetes medication or starting insulin during the prior 3 months. This interviewer-administered cross-sectional survey assessed multiple aspects of patient-physician interpersonal processes, diabetes-related distress, and diabetes medication-taking. Clinical history and HbA1c were collected from electronic medical records. Regression estimates and Structural Equation Modeling were used to test associations. RESULTS: Some communication scales indicated a significant relationship with total diabetes distress (P < 0.001). Diabetes medication-taking was associated with less diabetes distress (adjusted odds ratio [aOR]=0.45, P < 0.001), lower Hurried Communication (aOR=0.72, P = 0.013), higher Elicited Concerns (aOR=1.30, P = 0.012), and higher Explained Results (aOR=1.41, P < 0.001) scores. SEM analyses showed medication-taking behavior was associated with a 0.68 decrease in HbA1c. Hurried Communication and diabetes distress were directly associated with HbA1c. CONCLUSION: Aspects of patient-physician interpersonal processes at the time of intensifying diabetes treatment may be related to experiencing less distress, effective medication-taking, and improved HbA1c. PRACTICE IMPLICATIONS: The results are intended to inform communication strategies that physicians might incorporate into practice.

Impact of adherence goal awareness intervention on PDC in various settings: Does awareness help modify medication-taking behavior?

Background: Interventions to improve medication adherence in chronic conditions have shown limited success or sustainability. Previous data revealed that phone calls to patients regarding adherence goal awareness resulted in significant improvement in proportion of days covered (PDC). Objectives: The objective of this study was to explore specific pharmacist adherence interventions via phone in various practice settings. Methods: A prospective, randomized controlled study was conducted with patients who belonged to university-associated health care settings [ambulatory care, chain store, small health plan, and federally qualified health center (FQHC)]. At each site, patients with at least one chronic medication and a calculated PDC < 0.80 were randomized into control (n=115) and intervention (n=126) groups. Control groups (C) received usual pharmacy communication while intervention groups (X) were specifically called by a pharmacist to be informed of PDC goals and their commitment to adherence. PDC values were calculated 3 to 12 months for both groups the time of intervention, then compared with each patient's respective baseline/pre-PDC. Results: Data from a total of 241 patients were pooled to examine change in PDC. There was no significant difference between groups in baseline criteria or PDC. Comparing within groups, there were significant correlations between Pre- and Post-PDCs for the intervention group (X = 0.32 p < 0.05) alone. There were significant improvements from initial PDC to those calculated at the time of Post-intervention PDC within both groups, (C = 0.18 ± 0.28 p < 0.05) and (X = 0.16 ± 0.24, p < 0.05). Approximately 44% of all sampled patients reached their adherence goals (PDC ≥ 0.80) after 3-9 months. Conclusions: Results suggested that patient adherence behavior may improve after any call made by pharmacy staff. This communication and attention from the pharmacy may be enough for patients to consider their medication-taking habits without the need for discussing specific goals and importance of adherence.

Enabling sustained communication with patients for safe and effective management of oral chemotherapy: A longitudinal ethnography.

AIMS: To examine how patients received, understood, and acted on healthcare professional communication about their oral chemotherapeutic regimen throughout their treatment. DESIGN: A longitudinal ethnographic study. METHODS: Over 60 hr of observational data were recorded, in the form of field notes and audio-recordings from interactions among nine oncology doctors, six oncology nurses, eight patients, and 11 family members over a period of 6 months in outpatient departments in one hospital in Northern Ireland. Sixteen semi-structured interviews with patients and three focus groups with healthcare professionals were also carried out. This study took place from October 2013-June 2016. Data were thematically analysed. RESULTS: Three themes where identified from the data. These were initiating concordance through first communication about oral chemotherapy; which focused on initial communication during oncology consultations about oral chemotherapy, sustained communication of managing chemotherapy side effects; which was about how communication processes supported timely and effective side effect management and un-sustained communication of oral chemotherapy medication-taking practice; when patients and healthcare professionals failed to communicate effectively about chemotherapy medication-taking. CONCLUSION: The two most important factors in ensuring the optimal management of oral chemotherapeutic medicines are early recognition and appropriate response to side effects and the maintenance of safe and effective medication administration. This study found that oncology doctors and nurses engaged in sustained communication about the side effects of chemotherapy but did not focus their communication on safe administration after the first consultation. IMPACT: Based on this evidence, we recommend that healthcare professionals who provide oral chemotherapy for home administration should review their processes and procedures. Healthcare professionals need to ensure that they embed frequent communication for the duration of treatment between themselves and patients, including open discussion and advice, about side effects and medication administration.

Investigation on Household Medication-Taking Behavior and Affordability Among Patients Under Chronic Condition: A Survey Study in Gansu Province, China.

AIM: This study aimed to investigate the household medication-taking behavior and affordability of patients with chronic diseases in Gansu Province. As well as to propose suggestions to assist improvement of related policies. METHODS: A multistage stratified cluster sampling technique was used to select the research sites and households according to the WHO manual for the "Household Survey to Measure Access and Use of Medicines". The impact factors of medication-taking behavior were estimated using binary logistic regression models. Medication treatment affordability of hypertension patients was evaluated. RESULTS: A total of 1,080 completed questionnaires were collected, in which 690 families reported to have chronic patients in their home. The total number of chronic disease patients were 915. About 93% of the patient reported scheduled medicine intake. Approximately 86.60% of patients with chronic medical conditions were able to adhere to the physicians' prescriptions. Age, gender, and the number of household chronic disease patients were the main factors influencing whether the patients take medication. Respondents' self-reported monthly expenditure on household medicine accounted for 16.95% of their total monthly expenditure. The total cost of irbesartan and valsartan for hypertension treatment was two-fold higher than the minimum daily wage of the families. CONCLUSION: This study found that patients with chronic diseases have a high proportion of medication and medication compliance. However, family drug burden, especially for those living with hypertension are among the key challenges. Related policy needs to be revised to promote the affordability of medication under chronic conditions.

Exploring the perspectives on medication self-management among persons with spinal cord injury/dysfunction and providers.

RATIONALE: Spinal cord injury/dysfunction (SCI/D) is an exemplar condition with a high prevalence of secondary complications, chronic conditions and use of multiple medications (polypharmacy). Optimizing medication self-management is important for persons with SCI/D to improve outcomes; however, there is a lack of research on how healthcare/service providers and persons with SCI/D experience medication self-management. OBJECTIVE: To explore attitudes and experiences of medication self-management from the perspectives of persons with SCI/D and providers, and to explore the extent to which the Taxonomy of Everyday Self-management Strategies (TEDSS) framework captured participants' experiences with medication self-management. METHODS: In-depth, semi-structured interviews were conducted by telephone until data saturation was reached. Interviews were transcribed verbatim and analyzed using constant comparative approaches. The TEDSS framework was adapted and applied deductively. RESULTS: Fifty-one individuals participated in this study, 32 providers and 19 persons with SCI/D. Disease controlling strategies was the domain discussed in most detail by all participants. In this domain, participants discussed managing medications and treatments, monitoring/managing side effects, and controlling complications. Process strategies (problem-solving, decision-making) and resource strategies (seeking support) were the next most frequently discussed domains. Among all participant groups, there was a lack of detailed discussion of social interactions, health behaviour, and internal strategies. Medication self-management support was not extensively discussed by any group. CONCLUSION: This study highlighted the complex nature of medication self-management. While persons with SCI/D and providers discussed similar components of the TEDSS framework, providers had minimal reflections on the impact of medication self-management on everyday life. This study identified the need for explicit discussions between providers and persons with SCI/D, involving all components of self-management and self-management support in order to improve medication self-management.

Spinal cord injury and polypharmacy: a scoping review.

Purpose: The purpose of this scoping review was to map the scope of the literature on polypharmacy among individuals with spinal cord injury or dysfunction (SCI/D).Material and methods: Five electronic databases were searched for literature published between January 1990 and July 2018. The following keywords were searched using Boolean operators, wild cards, proximity operators and truncations: spinal cord injuries, multiple medications, polypharmacy. The initial search identified 1,459 articles; 1,098 remained after deduplication. Following the title and abstract screen, 81 full-texts were reviewed, and 18 met all of the eligibility criteria for inclusion in the review.Results: Of the 18 studies identified, less than half defined polypharmacy. Definitions varied in the types and number of medications. Older age, higher level of injury and greater severity of injury were factors related to polypharmacy. Negative clinical outcomes, such as drug-related problems and bowel complications were identified.Conclusions: This scoping review identified a paucity of research on polypharmacy post-SCI/D, highlighting a need for future research. To improve the state of knowledge, there is a need to better understand factors and clinical outcomes related to polypharmacy in persons with SCI/D and to explore experiences of persons with SCI/D, caregivers and clinicians relating to polypharmacy.Implications for rehabilitationPrescribers should be aware of the factors and negative clinical outcomes related to polypharmacy and spinal cord injuries/dysfunction, especially for patients with higher level and more severe injuries.Prescribers should work with their patients with spinal cord injuries/dysfunction to avoid inappropriate polypharmacy and to integrate appropriate alternatives to medications.Optimizing medication management should be a significant focus of spinal cord injury/dysfunction rehabilitation and research in order to develop targeted interventions that improve patient outcomes.

Exploring stroke survivors' self-efficacy in understanding and taking medication and determining associated factors: a cross-sectional study in a neurology clinic in Malaysia.

BACKGROUND AND AIM: Evidence-based prescribing practices for stroke-preventive medication have benefited stroke survivors; however, medication-nonadherence rates remain high. Medication understanding and use self-efficacy (MUSE) has shown great importance in medication-taking behavior, but its relationship with medication nonadherence in stroke-preventive regimens lacks exploration. The aim of this study was to determine the prevalence of MUSE and its association with nonadherence causes and other potential factors among stroke survivors in Malaysia. METHODS: This cross-sectional study was conducted among 282 stroke patients who provided informed consent and were in follow-up at the Neurology Outpatient Department of Hospital Kuala Lumpur, Malaysia. The study employed a data-collection form that gathered information on sociodemographics, clinical treatment, outcome measures on MUSE, and medication-nonadherence reasons. RESULTS: The prevalence of poor medication understanding and use self-efficacy among stroke patients was 46.5%, of which 29.1% had poor "learning about medication" self-efficacy, while 36.2% lacked self-efficacy in taking medication. Beliefs about medicine (74.02%) was the commonest reason for medication nonadherence, followed by medication-management issues (44.8%). In the multivariate model, independent variables significantly associated with MUSE were health literacy (AOR 0.2, 95% CI 0.069-0.581; P=0.003), medication-management issues (AOR 0.073, 95% CI 0.020-0.266; P<0.001), multiple-medication issues (AOR 0.28, 95% CI 0.085-0.925; P=0.037), beliefs about medicine (AOR 0.131, 95% CI 0.032-0.542; P=0.005), and forgetfulness/convenience issues (AOR 0.173, 95% CI 0.050-0.600; P=0.006). CONCLUSION: The relatively poor learning about medication and medication-taking self-efficacy in this study was highly associated with health literacy and modifiable behavioral issues related to nonadherence, such as medication management, beliefs about medicine, and forgetfulness/convenience. Further research ought to explore these underlying reasons using vigorous techniques to enhance medication understanding and use self-efficacy among stroke survivors to determine cause-effect relationships.

Medication-Taking Habit and Outcome of Glucosamine Sulfate for Osteoarthritis Patients Influenced by National Health Insurance Regulations in Taiwan.

This study compared the dosage and different medication-taking habits of glucosamine sulfate (GS) for osteoarthritis patients and evaluated the influence of the National Health Insurance (NHI) prescription guidelines. The subjects were collected from the Taiwan NHI Research Database from 1 January 2004, to 31 December 2008, and 10,501 osteoarthritis patients were included. Then, 271 patients who continuously used nonsteroidal anti-inflammatory drug (NSAIDs) and started to receive glucosamine for the first time since 2005 (no glucosamine use in 2004) were compared with 593 age-matched patients who continuously used NSAIDs but never received any glucosamine drugs from 2004 to 2008. The mean treatment duration of the glucosamine-treated and NSAID-treated groups was 40.38 ± 7.89 and 45.82 ± 3.89 months, respectively. The most common medication-taking habit was 250 mg 3 times a day for 3 months and discontinued for 3 months. It was as indicated and covered by the NHI. Only 0.7% of patients used the recommended daily dosage of 1500 mg. Patients using GS surprisingly had a higher incidence rate of joint replacement surgery than those who did not use GS. The NHI prescription guidelines may cause patient selection bias, which decreases the efficacy of GS. Moreover, patients tend to have an altered medication-taking habit, with a daily dosage of 750 mg, which is lower than the recommended therapeutic dose.

Oncologists' perspectives on adherence/non-adherence to adjuvant endocrine therapy and management strategies in women with breast cancer.

PURPOSE: Adherence to adjuvant endocrine therapy (AET) is suboptimal, and a range of variables have been explored for understanding patients' experiences and motivations for medication-taking. However, oncologists' views on adherence are poorly understood. The aim of this study was to explore oncologists' perspectives on adherence/non-adherence and their strategies to ensure patients continue with treatments to inform the development of potential modifiable interventions. METHODS: A qualitative study using in-depth, semi-structured interviews with 16 oncologists was conducted in Argentina. A stratified purposive sampling was used to recruit female and male participants from 3 health subsystems (private, social security, and public). Data were analyzed using the Framework approach. RESULTS: Oncologists believed patients' adherence was overall high and associated it with good tolerance of AET in comparison to chemotherapy, information provided, and patients feeling reassured (fear of recurrence). Non-adherence was not perceived as a major source of concern, and it was related to rare cases of severe side effects, young age, refusing treatment, losing the insurance plan, lack of education, and social circumstances. Patients' complaints of bothersome side effects were not identified as a main reason to discontinuation. Public and private sector patients, however, were perceived as having different attitudes toward side effects. Management strategies included medicine change, referral to support services, and a supportive relationship with the oncologist. CONCLUSION: Oncologists' perspectives on adherence/non-adherence to AET show similarities and significant differences with those in the literature based on patient-reported factors. Overall adherence was considered high, but the likelihood of unintentional non-adherence seems important in public sector patients. Information to patients should provide clear explanations on both severe and unpleasant side effects. Interventions to improve communication skills in oncologists and specialists responsible for survivorship care should be considered to strengthen patients' self-efficacy and effective medication-taking. Reliable data on adherence are needed.
