J Pharm Policy Pract 2024; 17:2371409. [PMID: 39015753 PMCID: PMC11251441 DOI: 10.1080/20523211.2024.2371409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Accepted: 06/18/2024] [Indexed: 07/18/2024] Open
Abstract
Background While previous research underscores the independent effect of the pharmacist-patient relationship on patient outcomes, it did not delve further into the patient-pharmacist relationship dynamics and their effects on reported outcomes. Therefore, this study aimed to assess whether patient-pharmacist relationship aspects mediate the association between patient personal and health characteristics, on the one hand, and adherence to medication and quality of life, on the other hand (QOL). Methods An online cross-sectional study was conducted between April 11 and 27, 2023. It enrolled 865 adults from all Lebanese governorates and used validated scales to measure the various concepts. Results The mean age was 32.52 ± 14.56 years, and 68.8% were female. Also, 79.3% reported having no chronic disease, and 57.7% indicated that getting nonprescription medications was the main reason for visiting a community pharmacy. The average routine intake of medications per day was 0.87 ± 1.78. Our key findings reveal a compelling association between worse health status and both increased medication non-adherence and reduced QOL. Sociodemographic factors were found to be correlated with QOL. Despite the considerable impact of demographic factors on patient expectations, our study challenges the expected mediation role of the pharmacist-patient relationship and counseling time on medication adherence. Nevertheless, patient expectations partially mediated the relationship between sociodemographic characteristics and QOL. Conclusion This study sheds light on the intricate dynamics between patient characteristics, health status, medication adherence, and QOL within the context of the patient-pharmacist relationships.

Abstract
Diabetes mellitus is a risk factor for Parkinson's disease (PD). While animal studies have supported the benefits of incretin-based therapies, including dipeptidyl peptidase-4 (DPP4) inhibitors, in PD, clinical research has yielded controversial results. This cohort study aimed to assess the relationship between PD incidence and the utilization of DPP4 inhibitor in diabetic patients. Using Taiwan's National Health Insurance Research Database from 2009 to 2018, diabetic patients receiving metformin plus at least one second-line oral antidiabetic (OAD) were enrolled. The patients were categorized as DPP4 inhibitor users and non-users. Propensity score matching was employed to establish a 1:1 ratio between DPP4 inhibitor users and non-users. Among the 205,910 patients enrolled, 149 were diagnosed with PD during follow-up. The incidence rate was 0.29 per 1000 person-years for DPP4 inhibitor users and 0.55 per 1000 person-years for the non-users. DPP4 inhibitor users exhibited a significantly lower risk of PD (adjusted hazard ratio, 0.51; 95% CI 0.39-0.68). Among DPP4 inhibitor users, vildagliptin showed the strongest correlation with a reduction in the risk of PD. This study demonstrates that the use of DPP4 inhibitors along with metformin in diabetic patients is associated with a lower risk of PD compared to those using other OADs.

BMC Health Serv Res 2023; 23:905. [PMID: 37620970 PMCID: PMC10464472 DOI: 10.1186/s12913-023-09904-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 08/10/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Medication non-adherence has become a striking problem among patients with chronic diseases worldwide. However, literature on prevalence, reasons and factors associated with medication non-adherence in Singapore general population is still lacking. This study aimed to (1) estimate the prevalence of intentional and unintentional medication non-adherence in young (aged 21-64 years) and older adults (aged ≥ 65 years), respectively; (2) identify and compare the main reasons for non-adherence; and (3) examine the association between potential factors and non-adherence in each group. METHODS This study sampled 1,528 community-dwelling adults on medications (young adults:766, older adults: 762) from a cross-sectional population health survey conducted in the northern and central regions of Singapore in 2018/2019. Self-reported medication non-adherence and its reasons were collected using a modified questionnaire and compared between the two groups. Multiple logistic regressions were conducted to examine the association between potential factors (e.g., social-demographic factors, smoking and drinking status, presence of diabetes, hypertension, or dyslipidaemia, and presence of depressive symptoms) and medication non-adherence in each group. RESULTS The prevalence of non-adherence was 38.4% and 22.3% in young and older adults, respectively, with young adults reporting higher unintentional and intentional non-adherence rates than older adults. "Afraid of developing drug dependence" was the most common reason in both groups (young:74.8% vs. old:73.5%). Compared to young adults (3.7%), "Not understanding medication labels" was more prevalent in older adults (8.8%). Presence of depressive symptoms was associated with non-adherence in both young (odds ratio [95% confidence interval]: 3.00 [1.79, 5.05]) and older adults (4.16 [2.31, 7.51]). Being employed (2.92 [1.76, 4.84]) and taking ≥ 2 medications (1.42 [1.04, 1.95]) had positive association while personal income of SGD1,000-4,000 (0.53 [0.36, 0.77]) and current smoking (0.61 [0.39, 0.95]) had inverse association with non-compliance in young adults. Diagnosis of diabetes, hypertension, or dyslipidaemia (2.63 [1.25, 5.53]) was associated with higher odds of non-compliance in older adults. CONCLUSIONS Young adults had higher prevalence of medication non-adherence than older adults. The main reasons for non-adherence reported by young and older adults were generally comparable. Presence of depressive symptoms was a risk factor of medication non-adherence in both groups.

Abstract
The relationship between renal impairment and diabetic peripheral neuropathy (DPN) remains inconclusive. We aim to investigate the risk factors for the occurrence of DPN in Taiwanese adults with type 2 diabetes mellitus (T2DM) and focus on renal impairment. A hospital-based study was conducted from 2013 to 2019 and 552 Taiwanese people who had T2DM without DPN at baseline were enrolled. DPN was diagnosed using the Michigan Neuropathy Screening Instrument. Potential risk factors were recorded, including patient’s sociodemographic factors, current medication usage and biochemical markers. As of 2019, 73 developed DPN and 479 had no DPN. The cumulative incidence during the 6-year period was 13.22%. Multivariable logistic regression analysis revealed that lower estimated glomerular filtration rate (eGFR) (odds ratio [OR] 0.98, p = 0.005), advanced age (OR 1.06, p = 0.001), increased body weight (OR 1.04, p = 0.018), duration of DM (OR 1.05, p = 0.036) and male gender (OR 3.69, p = 0.011) were significantly associated with future DPN. In addition, patients with T2DM under the age of 65 with higher serum creatinine concentration (OR 8.91, p = 0.005) and higher baseline HbA1C (OR 1.71, p < 0.001) revealed significantly associated with future DPN. In conclusion, this is the first large scaled hospital-based study with long term follow-up to investigate risk factors for DPN in Taiwanese. Lower eGFR and higher serum creatinine concentration, particularly in people under the age of 65, are predictors of future DPN in Taiwanese people with T2DM. Other predictors included advanced age, increased body weight, duration of DM, male gender for all ages and HbA1c in enrolled patients under the age of 65. Our study not only confirms the association between renal impairment and future DPN but also provides a commonly available assessment to predict the future DPN.

Adherence to and persistence with antidiabetic medications and associations with clinical and economic outcomes in people with type 2 diabetes mellitus: A systematic literature review. Diabetes Obes Metab 2022; 24:377-390. [PMID: 34779107 PMCID: PMC9299643 DOI: 10.1111/dom.14603] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 10/21/2021] [Accepted: 10/31/2021] [Indexed: 12/28/2022]
Abstract
We designed a systematic literature review to identify available evidence on adherence to and persistence with antidiabetic medication in people with type 2 diabetes (T2D). Electronic screening and congress searches identified real-world noninterventional studies (published between 2010 and October 2020) reporting estimates of adherence to and persistence with antidiabetic medication in adults with T2D, and associations with glycaemic control, microvascular and/or macrovascular complications, hospitalizations and healthcare costs. Ninety-two relevant studies were identified, the majority of which were retrospective and reported US data. The proportions of patients considered adherent (median [range] 51.2% [9.4%-84.3%]) or persistent (median [range] 47.7% [16.9%-94.0%]) varied widely across studies. Multiple studies reported an association between greater adherence/persistence and greater reductions in glycated haemoglobin levels. Better adherence/persistence was associated with fewer microvascular and/or macrovascular outcomes, although there was little consistency across studies in terms of which outcomes were improved. More adherent and more persistent patients were typically less likely to be hospitalized or to have emergency department visits/admissions and spent fewer days in hospital annually than less adherent/persistent patients. Greater adherence and persistence were generally associated with lower hospitalization costs, higher pharmacy costs and lower or budget-neutral total healthcare costs compared with lower adherence/persistence. In conclusion, better adherence and persistence in people with T2D is associated with lower rates of microvascular and/or macrovascular outcomes and inpatient hospitalization, and lower or budget-neutral total healthcare expenditure. Education and treatment strategies to address suboptimal adherence and persistence are needed to improve clinical and economic outcomes.

Abstract
BACKGROUND Multimorbidity is highly prevalent amongst older people. Compared with those with a single disease, older people with multimorbidity are more susceptible to medication nonadherence, which causes adverse health outcomes and increased health care costs. The effectiveness of interventions for improving medication adherence in this population is still unclear. OBJECTIVE To evaluate the effectiveness of interventions to improve medication adherence for community-dwelling older people with multimorbidity. DESIGN Systematic review and meta-analysis. DATA SOURCES Ten databases: Airiti Library, China National Knowledge Infrastructure, Cochrane CENTRAL, EBSCO CINAHL, OVID EMBASE, OVID MEDLINE, Proquest Central, PsycINFO, Wanfang Database and Web of Science Core Collection. REVIEW METHODS Studies evaluating the effects of interventions on medication adherence in community-dwelling older people with multimorbidity were included. Two researchers independently performed the study selection, data extraction and risk assessment. Intervention effects were pooled by random-effects meta-analysis. RESULTS A total of nine studies with 3,292 participants were included. Studies on self-management interventions revealed a significant and modest improvement in medication adherence (n = 3 studies; SMD 0.52; 95% CI 0.04 to 0.99; p = 0.03, I2 = 43%). Studies using electronic health interventions demonstrated a small yet significant benefit for medication adherence (n = 2 studies; SMD 0.22; 95% CI 0.02 to 0.42; p = 0.03, I2 = 0%). There was no pooled significant effect of medication review on medication adherence (n = 4 studies; SMD -0.03; 95% CI -0.21 to 0.15; p = 0.74, I2 = 68%). Most of the studies failed to yield a significant improvement in patients' health outcomes. CONCLUSIONS Self-management interventions and electronic health interventions might be effective in improving medication adherence for older people with multimorbidity. Future adherence interventions are needed to demonstrate improvements in medication adherence and health outcomes. PROSPERO REGISTRATION NUMBER CRD42020150500.

Abstract
CONTEXT Comorbid depression in patients with diabetes deteriorates the prognosis. Antidepressants might attenuate the adverse effects of depression; however, they are associated with cardiometabolic adverse effects. OBJECTIVE This study aimed to explore the association between antidepressant treatment and advanced diabetic complications and mortality among patients with depression and diabetes mellitus. METHODS We conducted a nationwide retrospective cohort study of 36 276 patients with depression and newly treated diabetes mellitus using Taiwan's universal health insurance database. Antidepressant treatment patterns within a 6-month window were classified into none, poor, partial, and regular use, and we accounted for time-dependent variables in the Cox proportional hazards regression analysis with adjustment for time-dependent comorbidity and concomitant use of medications. Different classes of antidepressants were compared. Macro- and microvascular complications, as well as all-cause mortality, were the main outcomes. Benzodiazepines were chosen as negative control exposure. RESULTS Compared with poor use of antidepressants, regular use was associated with a 0.92-fold decreased risk of macrovascular complications and a 0.86-fold decreased risk of all-cause mortality but not associated with microvascular complications. Regular use of selective serotonin reuptake inhibitors was associated with a 0.83- and 0.75-fold decreased risk of macrovascular complications and all-cause mortality, respectively. Regular use of tricyclic or tetracyclic antidepressants was associated with a 0.78-fold decreased risk of all-cause mortality. Regular use of benzodiazepine showed no association with diabetic outcomes. CONCLUSION Regular antidepressant use was associated with lower risk of advanced diabetic complications compared with poor adherence. Clinicians should emphasize antidepressant treatment adherence among patients with depression and diabetes mellitus.

A 12-Year Retrospective Study of the Prevalence of Anticholinergic Polypharmacy and Associated Outcomes Among Medicare Patients with Overactive Bladder in the USA. Drugs Aging 2021; 38:1075-1085. [PMID: 34746992 PMCID: PMC8651576 DOI: 10.1007/s40266-021-00901-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/19/2021] [Indexed: 11/24/2022]
Abstract
Background and Objective Antimuscarinics, drugs with anticholinergic properties, are frequently prescribed for overactive bladder, and anticholinergic burden is associated with adverse events. The “Polypharmacy: Use of Multiple Anticholinergic Medications in Older Adults” (Poly-ACH) measure was developed by the Pharmacy Quality Alliance and is used by the Centers for Medicare and Medicaid Services. Using the Poly-ACH measure, we assessed the prevalence of anticholinergic polypharmacy among Medicare patients in the USA with overactive bladder and determined associations between polypharmacy and medical conditions, care, and spending. Methods This was a retrospective cohort study of Medicare beneficiaries with overactive bladder (coverage period: 2006–2017). Anticholinergic polypharmacy, measured by the Poly-ACH, was defined as concurrent use of two or more anticholinergics, each with two or more prescription claims on different dates of service for ≥ 30 cumulative days. Change in annual frequency of anticholinergic polypharmacy was assessed using logistic regression. Associations between anticholinergic polypharmacy over 3 years and falls, fractures, mental status, and medical care spending were assessed with longitudinal regression models. Results In total, 226,712 patients contributed 940,201 person-years of follow-up after overactive bladder diagnosis. The share of patients meeting the Poly-ACH definition was 3.3% in 2006 and 1.7% in 2017. Women and nursing home residents had higher risks of anticholinergic polypharmacy. Having 1 year or more of positive Poly-ACH status in the 3 years prior was associated with higher rates of all outcomes. Conclusions Anticholinergic polypharmacy was uncommon among older adults with overactive bladder. Prevalence was higher among women and nursing home residents, and it was associated with negative outcomes, highlighting potential longitudinal implications of anticholinergic burden.

Behavioral Factors Associated with Medication Nonadherence in Patients with Hypertension. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189614. [PMID: 34574540 PMCID: PMC8469687 DOI: 10.3390/ijerph18189614] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 09/08/2021] [Accepted: 09/09/2021] [Indexed: 11/26/2022]
Abstract
Medication nonadherence is associated with an increased risk of complications in hypertensive patients. We investigated behavioral factors associated with medication nonadherence in hypertensive patients in southern Taiwan. Using questionnaires, we collected data regarding clinicodemographic characteristics and nonadherence behaviors from 238 hypertensive patients. We assessed the self-reported prevalence of specific behaviors of medication nonadherence and investigated factors associated with each behavior using multivariable logistic regression analysis. The most common behavior of medication nonadherence was forgetting to take medication (28.6%), followed by discontinuing medication (9.2%) and reducing the medication dose (8.8%). Age ≥ 65 years (adjusted odds ratio [aOR] = 0.32, 95% confidence interval [CI] = 0.15–0.69) and male sex (aOR = 2.61, CI = 1.31–5.19) were associated with forgetting to take medication. The presence of comorbidities (diabetes, kidney disease, or both) and insomnia (aOR = 3.97, 95% CI = 1.30–12.1) was associated with reducing the medication dose. The use of diet supplements was associated with discontinuing the medication (aOR = 4.82, 95% CI = 1.50–15.5). Compliance with a low oil/sugar/sodium diet was a protective factor against discontinuing medication (aOR = 0.14; 95% CI = 0.03–0.75). The most pervasive behavior associated with medication nonadherence among hypertensive patients was forgetting to take medication. Age <65 years, male sex, comorbidities, insomnia, noncompliance with diet, and the use of dietary supplements were specifically associated with medication nonadherence.

Abstract
BACKGROUND The burden of stroke weighs heavily in developing countries where recurrence rates clearly exceed that of developed countries. The impact of nonadherence to antithrombotic treatment within this context has been poorly investigated. OBJECTIVE The objective of this study was to evaluate patients with recurrent ischemic stroke in Egypt and Germany with focus on stroke subtype distribution and adherence to antithrombotic therapy. METHODS We conducted a comparative cross-sectional retrospective cohort study enrolling consecutive patients hospitalized for recurrent ischemic stroke in 2017 in 2 academic centers. Data were collected on demographics, risk factors, stroke subtypes, and medication adherence. Nonadherence to antithrombotic agents was analyzed at the time point of index stroke (recurrent stroke). Predictors of nonadherence were analyzed using logistic regression. RESULTS A total of 373 Egyptian and 468 German patients with ischemic stroke were included. The proportion of recurrent ischemic stroke among all patients was higher in the Egyptian cohort compared to the German cohort (33 vs. 10%, p < 0.05). Small-vessel occlusion stroke was the most frequent subtype in Egyptians, with a significantly greater proportion than in Germans (45 vs. 26%, p < 0.05). Nonadherence to antiplatelets at the time point of the recurrent stroke was higher in Egyptians than in Germans (82 vs. 19%, p < 0.001). Low educational attainment among Egyptians (OR 0.14, 95% CI [0.00-0.19], p < 0.01) and high comorbidity scores among Germans (OR 2.45, 95% CI [1.06-5.66], p < 0.05) were found to be predictors of nonadherence to antithrombotic treatment. CONCLUSIONS The large stroke recurrence burden in Egypt may be partly explained by differing adherence to secondary preventative antithrombotic pharmacotherapy. Predictors of medication nonadherence have to be addressed to reduce stroke recurrence disparities.
