Adherence to controller asthma medications: 6-month prevalence across a US community pharmacy chain

Non‐adherence to controller asthma medications is an important public health problem. It is estimated to occur in 30–70% of individuals and is a significant risk factor for asthma morbidity and mortality. The aim of this study was to determine the level of adherence, as indicated by refill rates, to controller asthma medications in a community pharmacy setting.

Identifying subtypes of patients with neovascular age-related macular degeneration by genotypic and cardiovascular risk characteristics.

BackgroundOne of the challenges in the interpretation of studies showing associations between environmental and genotypic data with disease outcomes such as neovascular age-related macular degeneration (AMD) is understanding the phenotypic heterogeneity within a patient population with regard to any risk factor associated with the condition. This is critical when considering the potential therapeutic response of patients to any drug developed to treat the condition. In the present study, we identify patient subtypes or clusters which could represent several different targets for treatment development, based on genetic pathways in AMD and cardiovascular pathology.MethodsWe identified a sample of patients with neovascular AMD, that in previous studies had been shown to be at elevated risk for the disease through environmental factors such as cigarette smoking and genetic variants including the complement factor H gene (CFH) on chromosome 1q25 and variants in the ARMS2/HtrA serine peptidase 1 (HTRA1) gene(s) on chromosome 10q26. We conducted a multivariate segmentation analysis of 253 of these patients utilizing available epidemiologic and genetic data.ResultsIn a multivariate model, cigarette smoking failed to differentiate subtypes of patients. However, four meaningfully distinct clusters of patients were identified that were most strongly differentiated by their cardiovascular health status (histories of hypercholesterolemia and hypertension), and the alleles of ARMS2/HTRA1 rs1049331.ConclusionsThese results have significant personalized medicine implications for drug developers attempting to determine the effective size of the treatable neovascular AMD population. Patient subtypes or clusters may represent different targets for therapeutic development based on genetic pathways in AMD and cardiovascular pathology, and treatments developed that may elevate CV risk, may be ill advised for certain of the clusters identified.

Qualitative interviews regarding pharmacist prescribing in the community setting

PURPOSE The perceived demand for and barriers to pharmacist prescribing in the community pharmacy setting were studied. METHODS Qualitative interviews were conducted with 19 consumers, 20 community pharmacists, and 8 reimbursement decision-makers from payer organizations between April and June 2015. Respondents were invited to participate in a daylong interview process online. Interviews with consumers and pharmacists were conducted using online bulletin board technology. Telephone interviews were conducted with reimbursement decision-makers. As with all qualitative research, the sample sizes used were restrictive and sufficient to gauge the perceptions of those respondents only. Interview responses were not intended to be generalizable to the groups or populations from which the respondents came. RESULTS There was a continuum of interest in pharmacist prescribing across the three constituencies. Consumers were predominantly resistant to the notion; however, one third were more positive about the idea. Community pharmacists were more open, particularly when prescribing was restricted to a limited set of conditions or medications. Reimbursement decision-makers were most receptive to the notion. Key barriers to pharmacist prescribing included low awareness of current pharmacist prescribing authority among consumers, concerns about the adequacy of pharmacist training, potential conflicts of interest when the prescriber was also a dispenser, and potential liability issues. CONCLUSION Consumer respondents were generally resistant to the notion of pharmacist prescribing, with most viewing pharmacists as dispensers and not prescribers. Community pharmacists were more open to the idea, while reimbursement decision-makers were the most receptive to the notion of pharmacist prescribing.

Patient preferences for healthcare delivery through community pharmacy settings in the USA: A discrete choice study

In order to improve public health, it is necessary to facilitate patients’ easy access to affordable high‐quality primary health care, and one enhanced approach to do so may be to provide primary healthcare services in the community pharmacy setting. Discrete choice experiments to evaluate patient demand for services in pharmacy are relatively limited and have been hampered by a focus on only a few service alternatives, most focusing on changes in more traditional pharmacy services. The study aim was to gauge patient preferences explicitly for primary healthcare services that could be delivered through community pharmacy settings in the USA, using a very large sample to accommodate multiple service delivery options.

Quality of Life with Macular Degeneration Is Not as Dark as It May Seem: Patients' Perceptions of the MacDQoL Questionnaire.

To determine the perceived relevance and value of an individualized measure of the impact of macular degeneration on quality of life (QoL) for elderly people with Age-Related Macular Degeneration (AMD) in the USA, through the assessment of the suitability of the measure’s domains and by gaining a deeper insight into the impact of AMD on patients’ QoL vis-á-vis these domains, community-dwelling older adults in the metropolitan Salt Lake City, Utah area were interviewed using the macular degeneration on quality of life (MacDQoL) instrument. Participants felt that the MacDQoL was a relevant instrument for use in this US study population, though it could be improved by adding items pertaining to transportation, and independent driving, in particular, as an important QoL indicator. The emerging theme from analysis of the respondent’s commentary was that, in spite of AMD, these respondents were committed to engage in, and enjoy life. This is an important concept for clinicians and those who offer support programs to integrate into their care planning and reinforce in messaging to patients with the condition.

Factors predicting self-reported medication low adherence in a large sample of adults in the US general population: A cross-sectional study

Objectives The study objective was to determine the level and correlates of self-reported medication low adherence in the US general population. Setting A 30 min cross-sectional online survey was conducted with a national sample of adults. Participants 9202 adults (aged 18+) who had filled at least three or more prescriptions at a community pharmacy in the past 12 months. Primary and secondary outcome measures Self-reported medication adherence was measured with the 8-item Morisky Medication Adherence Scale. Results Low adherence was reported by 42.0%, 29.4% had medium adherence and 28.6% had high adherence. Low adherence was significantly associated with: lower age, being of Hispanic origin or African-American, having difficulty with healthcare, medication or transportation costs, needing the support of others to access primary care, health limiting activity, using multiple providers, infrequent visits to primary care providers and visiting an emergency department >3 times in last 12 months. Conclusions A very high level of low medication adherence is seen in the general population, particularly for ethnic minorities, those who use multiple healthcare providers and those who experience barriers to access for regular primary care. As clinical, patient education and counselling, and healthcare policy initiatives are directed to tracking the problem of low medication adherence, these should be priority populations for research and interventions.

Pharmacist’s Demand for Optimal Primary Care Service Delivery in a Community Pharmacy: The OPTiPharm Study

Background: The US population continues to expand providing the need for primary health care services. Community pharmacies integrated with medicine may provide greater access while providing high quality care. Objective: To gauge pharmacists’ demand for primary health care services delivered through community pharmacies. Methods: An online survey was administered to determine community pharmacists’ preferences for varying primary care services that could be offered in the community pharmacy setting. A Discrete Choice Experiment was employed to show pharmacists competing scenarios with varied primary care service offerings in the community pharmacy setting. Attributes evaluated were operation hours, service provider, medical records, service logistics, physical examinations, point-of-care diagnostic testing, preventative care, and drug prescribing. Respondents chose the scenario most likely to induce switching employment from base pharmacy to one providing advanced services. Results: The optimal service delivery model from 291 community pharmacists comprised: inclusion of patient prescriptions and health information into the patient’s medical record; provision of point of care testing and vital sign, including blood pressure, heart rate and breathing rate, and blood sugar and cholesterol measurement; and pharmacists prescribing (under physician oversight). Pharmacists were 4 times more likely to switch employment from their current pharmacy to their choice for advanced pharmacy services. Pharmacist demand was highest among those with a PharmD, less experience, working >40 hours per week, and in rural areas. Conclusions: This study provides empirical support for the model of pharmacists playing a greater role in the provision of primary care health services through community pharmacy settings.

Adherence to Glaucoma Medications Over 12 Months in Two US Community Pharmacy Chains.

This study determined the degree of adherence to medications for glaucoma among patients refilling prescriptions in community pharmacies. Methods: Data abstracted from the dispensing records for 3615 adult patients (18 years or older, predominantly over 45) receiving glaucoma medications from two retail pharmacy chains (64 stores in total) were analyzed. From a 24-month historic data capture period, the 12-month levels of adherence were determined using standard metrics, the proportion of days covered (PDC) and the medication possession ratio (MPR). The overall 12-month mean PDC was only 57%, and the mean MPR was 71%. Using a criterion by which 80% coverage was considered satisfactory adherence, only 30% had satisfactory overall 12-month PDC coverage, and only 37% had satisfactory overall 12-month MPR coverage. Refill adherence increased with age and was highest in the 65-and-older age group (p < 0.001). Differential adherence was found across medication classes, with the highest satisfactory coverage seen for those taking alpha2-adrenergic agonists (PDC = 36.0%; MPR = 47.6%) down to those taking direct cholinergic agonists (PDC = 25.0%; MPR = 31.2%) and combination products (PDC = 22.7%; MPR = 31.0%). Adherence to glaucoma medications in the community setting, as measured by pharmacy refill data, is very poor and represents a critical target for intervention. Community pharmacists are well positioned to monitor and reinforce adherence in this population.

Prevalence and correlates of bleeding and emotional harms in a national US sample of patients with venous thromboembolism: A cross-sectional structural equation model

INTRODUCTION Venous thromboembolism (VTE) including deep vein thrombosis (DVT) or pulmonary embolism (PE) is associated with reduced survival, poorer quality of life, and substantial health-care-costs. Limited research, primarily qualitative, suggests that those with VTE may have elevated fear of recurrence, and associated emotional dysfunction and distress. METHODS A national online survey was administered to 907 patients who had experienced a VTE event in the past two years. The survey assessed for the prevalence of self-reported bleeding harms associated with VTE, the levels of anxiety, depression, cognitive dysfunction and distress experienced by patients, and a range of potential psychosocial correlates that may be associated with these bleeding or emotional harms. RESULTS The majority (63.0%) of respondents had experienced at least one bleeding related harm following their VTE diagnosis, and 40.6% indicated they experienced fear of another clot often or almost all the time. One-in-four (24.7%) and one-in-ten (11.6%) had abnormal levels of anxiety and depression, respectively. Structural equation modeling was used to define two composite latent bleeding harm and emotional harm factors. Emotional and bleeding harms were associated with younger age, a belief that ones health is due to luck, having multiple comorbidities, having a history of prior VTE events, having multiple barriers to VTE care, and experiencing medical mistakes in diagnosis or treatment. Emotional harms were uniquely predicted by having poorer health literacy, having low self-reported medication adherence, belief others are responsible for ones health, and more recent VTE events. Bleeding harms were uniquely predicted by having a lower frequency of primary care provider contact and having a history of switching between warfarin and direct oral anticoagulants for VTE treatment. CONCLUSIONS The findings show high levels of self-reported bleeding and emotional harms in a general population of VTE sufferers that are clearly associated with readily identifiable demographic, health status, and psychosocial characteristics. These represent targets for intervention and changes in clinical practice.
