Can Physicians Affect Patient Adherence With Medication?

Following Physician's Advice in Late Life: The Roles of Health Beliefs and Health Status

Objective

This study aims to explore the influence of health-related locus of control beliefs such as belief in the role of health professionals in influencing patient health, cognitive functioning, and multimorbidity on adherence to physician's recommendations among older adults.

Methods

A cross-sectional study involving older adults (N=684, age range = 71-100 years) living in Clearwater, Florida, reported their adherence to physician's recommendations, cognitive functioning, physical health, and health-related locus of control beliefs. Ordered Logistic regression was used.

Results

Older adults who believed that health professionals influence health and a person is likely to recover from illness because other people take good care of him/her had higher adherence to physician's recommendations. Older adults who believed that their own action affects their health had lower odds of reporting adherence by 27%. Additionally, those with cognitive impairment had lower odds of reporting adherence by 38%. Functional limitations, multimorbidity, and self-image of health were not associated with adherence.

Conclusion

This is one of the first studies to consider the influence of locus of control beliefs on adherence of physician's recommendations among community dwelling older adults. With the exception of one item "My good health is largely a matter of good fortune", generally individuals with external locus of control had higher adherence. Our findings also underscore the policy and clinical significance of different health-related beliefs held by older adults.

The effect of two facets of physicians' environmental stress on patients' compliance with COVID-19 guidelines: moderating roles of two types of ego network

Drawing upon the Conservation of Resources Theory, this study seeks to examine the association between two dimensions of environmental stress experienced by physicians and patients' adherence to COVID-19 guidelines, within the context of a social network framework. A third-wave longitudinal study was employed to gather 439 valid data points in China. Social network analysis and structural equation model were used to test the conceptual model. The results reveal the pivotal role of physicians' environmental stress related to their work and family contexts in influencing patients' adherence to COVID-19 guidelines through the mediation of physicians' information sharing. The ego networks of physicians, encompassing both advice-seeking and friendship ties, were observed to negatively moderate the relationship between stress and resource depletion. Broadly, our study shows the importance of understanding physicians' stress caused by the working and family environments, as these factorsnot only impact the psychological well-being of physicians but also significantly affect patients' compliance with COVID-19 guidelines. In addition, the work offers a framework for understanding the impact of the ego advice-seeking network and the ego friend network.

Use of Traditional Remedies for Treatment of Diabetic Foot Ulcers: A Cross-Sectional Study at a Tertiary Center in Saudi Arabia

Patients with diabetic foot ulcer (DFU) are prone to major complications including amputations. Traditional remedies (TR) have been used to treat DFU around the world. This study aims to identify the prevalence of TR among patients with DFU in our local cohort and its effect on DFU. 1408 patients were included in the analysis. Data were collected retrospectively from patients' medical records. DFU characteristics include grading ulcers using the Wagner scale (WG) and infections (cellulitis and osteomyelitis). Ulcer management (UM) includes medical treatment, self-medical treatment, traditional treatment, and medical-traditional treatment. The mean age of the cohort was 60 years (SD = 12.4). The mean duration of diabetes was 18.6 years (SD = 9.3) and the mean duration of open wounds was 206.9 days (SD = 545.6). The majority were males (71%) and had type 2 diabetes (96%, SD = .204). Forty-three percent of patients were treated with TR (29% were self-prescribed and 14% prescribed by a physician) while 48% had medical treatment and 10% were self-treated using medical treatment. More than two-thirds of the cohort had cellulitis and/or osteomyelitis at the time of presentation. The use of traditional treatment was significantly associated with higher WG (WG 4 OR =  1.936, 95% CI: 1.338-2.800; WG 5 OR =  2.937, 95% CI:1.614-5.346; P < 0.05). Moreover, osteomyelitis was associated with medical-traditional treatment (OR = 1.608, 95% CI: 1.006-2.572; P < 0.05) and increased wound depth (WG 3 OR =  1.969, 95% CI: 1.193-3.250; WG 4 OR =  1.874, 95% CI: 1.115-3.15; P < 0.05). There is high use of TR for the treatment of DFU in our cohort. High Wagner-grade of foot ulcers and the presence of osteomyelitis were highly associated with DFU. This study showed for the first time the use of traditional potions by medical physicians. Both physicians and patients need to be made aware of the detrimental effects of using traditional methods on DFU.

Adherence during COVID-19: The role of aging and socio-economics status in shaping drug utilization

Our study investigates the potential impact that COVID-19 and lockdown restrictions may have had on drug utilization and the role of patient age and education in reshaping it. We focused on patients affected by diabetes mellitus, who are likely to suffer a higher degree of morbidity and mortality due to COVID-19. We used a bi-monthly administrative panel dataset from January 2019 to December 2020 from Liguria (Italy), one of the regions with the highest number of individuals over the age of 65 in Europe. The results demonstrated that, after the initial shock, when patients tried to increase their personal stock of drugs to overcome the risk of possible additional barriers generated by the coronavirus, the hoarding effect almost disappeared. Adherence has drastically reduced during the COVID-19 pandemic and has never reached pre-COVID levels again. Older and poorly educated patients seem to have suffered more from the restrictions imposed by the lockdown and fear of contagion and they may be the ideal target group when considering possible policy interventions to improve adherence.

A longitudinal assessment of chronic care pathways in real-life: self-care and outcomes of chronic heart failure patients in Tuscany

BACKGROUND

Worldwide healthcare systems face challenges in assessing and monitoring chronic care pathways and, even more, the value generated for patients. Patient-reported outcomes measures (PROMs) represent a valid Real-World Evidence (RWE) source to fully assess health systems' performance in managing chronic care pathways.

METHODS

The originality of the study consists in the chance of adopting PROMs, as a longitudinal assessment tool for continuous monitoring of patients' adherence to therapies and self-care behavior recommendations in clinical practice and as a chance to provide policy makers insights to improve chronic pathways adopting a patient perspective. The focus was on PROMs of patients with chronic heart failure (CHF) collected in the Gabriele Monasterio Tuscan Foundation (FTGM), a tertiary referral CHF centre in Pisa, Italy. During the hospital stay, CHF patients were enrolled and received a link (via SMS or email) to access to the first questionnaire. Follow-up questionnaires were sent 1, 7 and 12 months after the index hospitalisation. Professionals invited 200 patients to participate to PROMs surveys. 174 answers were digitally collected at baseline from 2018 to 2020 and analysed. Quantitative and qualitative analyses were conducted, using Chi2, t-tests and regression models together with narrative evidence from free text responses.

RESULTS

Both quantitative and qualitative results showed FTGM patients declared to strongly adhere to the pharmacological therapy across the entire pathway, while seemed less careful to adhere to self-care behavior recommendations (e.g., physical activity). CHF patients that performed adequate Self-Care Maintenance registered outcome improvements. Respondents declared to be supported by family members in managing their adherence.

CONCLUSIONS

The features of such PROMs collection model are relevant for researchers, policymakers and for managers to implement interventions aimed at improving pathway adherence dimensions. Among those, behavioral economics interventions could be implemented to increase physical activity among CHF patients since proven successful in Tuscany. Strategies to increase territorial care and support patients' caregivers in their daily support to patients' adherence should be further explored. Systematic PROMs collection would allow to monitor changes in the whole pathway organization. This study brings opportunities for extending such monitoring systems to other organizations to allow for reliable benchmarking opportunities.

Treatment adherence of COVID-19 patients getting medication at home

Introduction: Turkey has adopted outpatient treatment of COVID-19 since the beginning of the pandemic. In the outpatient treatment of COVID-19 in Turkey, only hydroxychloroquine was initially used, favipiravir was added to the treatment, and finally, hydroxychloroquine was removed from the treatment and only favipiravir was used. Our study aims to examine the adherence to the recommended treatment of people diagnosed with COVID-19 who have received outpatient treatment without hospitalization and their attitudes and declared behaviors towards using the medications they were given free of charge. Methods: This follow-up study was conducted between February 15, 2021, and May 15, 2021, by telephone survey method in the Lüleburgaz District of Kırklareli City. The study participants were 4368 people who were diagnosed with COVID-19 with a positive PCR test in Lüleburgaz District between February 15 and May 15, 2021, and were given hydroxychloroquine and/or favipiravir drugs for home use after being deemed suitable for outpatient treatment according to the guidelines of the Republic of Turkey Ministry of Health. Results: 88.1% (n = 3849) of the survey respondents reported using the given medications regularly, while 11.9% (n = 519) did not use them regularly. The most important socio demographic factor affecting the regular use was age, and the patient-centered factor was the sense of trust. Conclusion: In the fight against COVID-19, measures to increase the sense of trust of patients who are expected to adhere to the treatments should be considered a priority.

Discontinuity in care: Practice closures among primary care providers and patient health care utilization

We evaluate the consequences for patients of being matched to a new primary care provider due to practice closures. Using an event study and population-level data of patients and providers in Denmark, we find that the transition between providers is smooth; among re-matched patients, there is little change in primary care utilization at the extensive margin. Second, we document a 17% increase in fee-for-service per visit and a large increase in the probability that the patient initiates drug therapy targeting chronic and underdiagnosed diseases (hypertension, hyperlipidemia, and diabetes). Additionally, the re-matched patients are more likely to be admitted to inpatient care for these diseases. The increase in therapeutic initiation is not primarily because the new providers are relatively predisposed to prescribing these drugs. Instead, it appears that when patients match to new providers, there is a consequential reassessment of patients' medical needs which leads to the initiation of new treatment.

The role of pharmacy personnel in promoting adherence to antiretroviral therapy in the Eastern Cape: communication barriers and breakthroughs

Background: Many people living with HIV struggle to adhere to their antiretroviral therapy, leading to suboptimal health outcomes and increased costs to the healthcare system. Due to their unique training and position in the health care system, South African pharmacists and pharmacy support personnel have the potential to improve adherence through effective patient counselling. However, they are often underutilised and face multiple barriers to providing these services. The aim of this study was to examine how pharmacists and pharmacy personnel view their impact upon the medication adherence behaviours of people living with and receiving medication therapy for HIV.Methods: The study used an exploratory qualitative research design. Our research team conducted in-depth interviews with 24 pharmacy personnel working in public health clinics in the Eastern Cape of South Africa, then used thematic analysis of the qualitative research data to determine the results.Results: Pharmacy personnel identified three key sets of communication challenges that limited effective patient counselling on antiretroviral therapy. These included environmental barriers presented by clinic design, language barriers between patients and pharmacy personnel, and varying communication styles and education levels of pharmacy staff and patients. Additionally, pharmacy personnel described innovative strategies they use to improve patient-provider communication and address adherence issues.Conclusions: Pharmacy personnel working in public health clinics face daily communication challenges as they attempt to provide counselling to patients with HIV. Both the clinic environment and the complex nature of HIV treatment serve as barriers to patient comprehension. In the face of these challenges, pharmacy personnel do their best to implement strategies that enhance patient counselling and address concerns about adherence. Increased attention should be paid to reducing the barriers to pharmacy-based patient counselling and utilising pharmacy personnel to enhance patient understanding and adherence to antiretroviral therapy.

Potentially inappropriate prescriptions: Associations with the health insurance contract and the quality of the patient-physician relationship?

CONTEXT

Potentially Inappropriate Prescriptions (PIP) are often used as an indicator of potential drug overuse or misuse to limit adverse drug events in older people.

OBJECTIVE

To determine whether PIP exposure differs as a function of the patient's health insurance scheme and the patient-physician relationship.

METHODS

Our dataset was collected from two surveys delivered to two cohorts of the Swiss Lc65+ study, together with a stratified random sample of older people in the Swiss canton of Vaud. The study sample consisted of 1,595 people aged 68 years and older living in the community and reporting at least one prescription drug. Logit regression models of PIP risk were run for various categories of variables: health related, socioeconomic, health insurance scheme and patient-physician relationship.

RESULTS

17% of our respondents had at least one PIP. Our results suggested that being enrolled in a health plan with restriction in the patient's choice of providers and having higher deductibles were associated with lower PIP risk. PIP risk did not differ as a function of the quality of the patient-physician relationship.

CONCLUSION

Our study helps to raise awareness about the organizational risk factors of PIP and, more specifically, how health insurance contracts could play a role in improving the management of drug consumption among community-dwelling older people.

Physician-Level Cost Control Measures and Regional Variation of Biosimilar Utilization in Germany

Biologic drugs represent a large and growing portion of health expenditures. Increasing the use of biosimilars is a promising option for controlling spending growth in pharmaceutical care. Amid the considerable uncertainty concerning physicians’ decision to prescribe biosimilars, explicit cost control measures may help increase biosimilar use. We analyze the role of regional cost control measures for biosimilars and their association with physician prescriptions in ambulatory care in Germany. We collect data on cost control measures implemented by German physician associations and national claims data on statutory health insurance covering 2009 to 2015. We perform panel regressions that include time and physician fixed effects to identify the average associations between cost control measures and biosimilar share/use while controlling for unobserved physician heterogeneity, patient structure, and socioeconomic factors. We identify 44 measures (priority prescribing, biosimilar quota) for erythropoiesis-stimulating substances, filgrastim, and somatropin. Estimates of cost control measures and their consequences for biosimilar share and use are heterogeneous by drug, measure type, and physician group. Across specialists, biosimilar quotas accounted for 5.13% to 9.75% of the total average biosimilar share of erythropoiesis-stimulating substances. Explicit quota regulations are more effective than priority prescribing. Regional variation in biosimilar use can be partly attributed to the presence of cost control measures.

Primary care physician practice styles and patient care: Evidence from physician exits in Medicare

Primary care physicians (PCPs) provide frontline health care to patients in the U.S.; however, it is unclear how their practice styles affect patient care. In this paper, we estimate the long-lasting effects of PCP practice styles on patient health care utilization by focusing on Medicare patients affected by PCP relocations or retirements, which we refer to as "exits." Observing where patients receive care after these exits, we estimate event studies to compare patients who switch to PCPs with different practice style intensities. We find that PCPs have large effects on a range of aggregate utilization measures, including physician and outpatient spending and the number of diagnosed conditions. Moreover, we find that PCPs have large effects on the quality of care that patients receive, and that all of these effects persist for several years. Our results suggest that switching to higher-quality PCPs could significantly affect patients' longer-run health outcomes.

Adherence to medical follow-up recommendations reduces hospital admissions: Evidence from diabetic patients in France

The aim of this study was to document the extent to which diabetic patients who adhered to required medical follow-ups in France experienced reduced hospital admissions over time. The main assumption was that enhanced monitoring and follow-up of diabetic patients in the primary care setting could be a substitute for hospital use. Using longitudinal claim data of diabetic patients between 2010 and 2015 from MGEN, a leading mutuelle insurance company in France, we estimated a dynamic logit model with lagged measures of the quality of adherence to eight medical follow-up recommendations. This model allowed us to disentangle follow-up care in hospitals from other forms of inpatient care that could occur simultaneously. We found that a higher adherence to medical guidance is associated with a lower probability of hospitalization and that the take-up of each of the eight recommendations may help reduce the rates of hospital admission. The reasons for the variation in patient adherence and implications for health policy are discussed.

Improving Medication Understanding and Adherence Using Principles of Memory and Metacognition: In Press - Policy Insights from Behavioral and Brain Sciences

More than half of older adults regularly take multiple medications. Rates of medication non-adherence are high, which undermines both patients' health and the economy. Memory and metacognitive factors (such as misplaced confidence) help explain why patients across the lifespan may not understand or follow prescribed regimens. These factors include difficulties in remembering confusing information; patients' and practitioners' potential overconfidence in memory; and misunderstandings about memory. Patients, practitioners, and the public can use these principles to improve memory, enhance understanding, and promote metacognitive accuracy with respect to complex medication information, which may increase the likelihood of adherence.

Big Data: Will It Improve Patient-Centered Care?

Within a generation, empirical researchers have experienced unprecedented increases in the availability of data. 'Big data' has arrived with considerable hype and a sense that these are dramatic shifts in the research environment that have wide-reaching implications across many disciplines. There is no doubt that the analysis of new and varied sources of data currently available to researchers in health have the potential to better measure, monitor and describe health outcomes of patients and to uncover interesting patterns in how patients respond to treatments and interact with the health system. What is less clear is whether answers are readily available to more nuanced and substantive research questions. Here, the data-rich environment needs to be complemented by considerable research effort developing novel research designs and generating new and improved methods of analysis. Importantly, this will require researchers to be able to combine data from multiple sources and to be pro-active in data collection.

Patient compliance with venous thromboembolism prophylaxis (VTE)

Venous thromboembolic disease (VTE) comprises pulmonary embolism (PE) and deep vein thrombosis (DVT), and causes morbidity and mortality, particularly in trauma and orthopaedic patients. Prevalence of 0.9% and 1.2% respectively are reported, with mortality rates up to 13.8%. Chemical thromboprophylactic agents including low molecular weight heparin (LMWH) are considered cost effective in reducing VTE risk. Evidence for anti-platelets including Aspirin for VTE prophylaxis is less compelling and is not supported as monotherapy. There has been no published data on patient compliance with LMWH in trauma outpatients. We aimed to determine whether trauma outpatients accept LMWH after discussing their VTE risk and the evidence for prophylaxis. For those accepting prophylaxis, we also investigated their compliance for the duration of immobilisation. Lower limb injured patients treated with external immobilisation over a 6 month period at our major trauma centre were included. On completion of immobilisation, they were requested to complete a 17-point questionnaire. Patients declining injectable subcutaneous LMWH as prophylaxis were offered Aspirin 75 mg as a second line agent. Seventy-five questionnaires were completed and five were excluded. Nineteen patients required surgical intervention for their injury, 51 were managed non-operatively. Thirty-one patients accepted LMWH and 30 chose Aspirin as an alternative. Nine patients declined or were not commenced on prophylaxis. Nineteen reported no missed Aspirin doses and 25 reported no missed LMWH doses. No patients reported missed doses due to pain, side effects or cessation of treatment for another reason. The mean average pain score recorded on the VAS was 3.8. No patients in the study were diagnosed with a VTE. LMWH is a recognised chemical thromboprophylactic and is well tolerated by patients for VTE risk reduction in lower limb immobilised outpatients. With poor evidence supporting Aspirin as a solo prophylactic agent, our local policy has withdrawn Aspirin for this purpose.
