Medical behaviours and medication adherence of older hypertensive patients in different medical insurance programs in Beijing, China: a cross-sectional study

BACKGROUND

Grassroots medical institutions are the primary "battlefield" of hypertension management based on hierarchical diagnosis and treatment policies in China. There is a considerable difference in the insured population and reimbursement ratio between different medical insurance programs. The management of hypertension directly affects the development trend of cardiovascular and cerebrovascular diseases.

METHODS

To understand the difference between different medical insurance programs regarding the management of older hypertensive patients, all outpatients aged 60 and above with hypertension in the basic medical insurance database of Beijing, China, from April 1, 2019, to January 31, 2020, were included. Medical behaviours included patients' choice of hospital level, type of hospital, number of hospitals visited, grassroots medical institutions and cross-district visits. Medication adherence was evaluated by calculating the medication possession ratio of antihypertensive medications. First, we adopted a statistical description for medical behaviours and medication adherence. Then, multivariate logistic regression was used to analyse the influencing factors of medication adherence.

RESULTS

This study included 1.29 million patients with Urban Employee Basic Medical Insurance (UEBMI) and 0.31 million patients with Urban‒Rural Resident Basic Medical Insurance (URRBMI). The proportions of patients with UEBMI who chose tertiary hospitals, comprehensive hospitals, grassroots medical institutions and cross-district visits were 25.84%, 56.09%, 57.34% and 39.32%, respectively, while those of patients with URRBMI were 11.14%, 60.59%, 81.28% and 6.07%, respectively. The medication adherence rates of men and women taking one medication were 61.04% and 55.86%, respectively. UEBMI patients who took their medication accounted for 62.36%, while only 40.27% of URRBMI patients adhered to their medication. The percentages of young-old, old-old and oldest-old patients who took their antihypertensive medications were 58.05%, 59.09% and 56.78%, respectively. The adherence to taking ≥ 2 medications (35.47%) was lower than that to taking one medication (58.33%). The medication adherence rates of patients with UEBMI and URRBMI for taking ≥ 2 medications were 37.21% and 27.45%, respectively.

CONCLUSIONS

Patients with UEBMI were more inclined to choose tertiary hospitals and cross-district visits than patients with URRBMI. The adherence of patients with UEBMI was better than that of patients with URRBMI in China.

A Systematic Review of the Hill-Bone Compliance to Blood Pressure Therapy Scale

Background

Poor medication adherence hampers hypertension control and increases the risk of adverse health outcomes. Medication adherence can be measured with direct and indirect methods. The Hill-Bone Compliance to High Blood Pressure Therapy (HBCHBPT) Scale, one of the most popular adherence measures, indirectly assesses adherence to hypertension therapy in three behavioral domains: appointment keeping, diet and medication adherence.

Aim

To synthesize evidence on the use of the HBCHBPT Scale, including psychometric properties, utility in diverse patient populations, and directions for future clinical use and research.

Methods

We searched electronic databases, specifically CINAHL, PubMed, PsychInfo, Embase, and Web of Science. We included original studies that used the HBCHBPT Scale or its subscales to measure a health outcome, or methodological studies involving translations and validations of the scale. We extracted and synthesized data following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines.

Results

Fifty studies were included in this review, 44 on hypertension, two on diabetes, and others on other chronic conditions. The scale was successfully translated into numerous languages and used in descriptive and intervention studies. The scale demonstrated sound psychometric properties (Cronbach's α coefficient 0.75) and sensitivity to capture intervention effects when used to evaluate the effectiveness of high blood pressure adherence interventions. The medication-taking subscale of HBCHBPT performs best and is widely used in diverse contexts to assess medication adherence for chronic conditions.

Conclusion

The HBCHBPT Scale has high versatility globally and has been used in various settings by various healthcare worker cadres and researchers. The scale has several strengths, including high adherence phenotyping capabilities, contributing to the paradigm shift toward personalized health care.

Factors Influencing Medication Adherence in Elderly Patients with Hypertension: A Single Center Study in Western China

Purpose

To develop and empirically test a conceptual model that explains the factors influencing antihypertensive medication adherence behavior in elderly patients in a city in western China.

Patients and Methods

The conceptual model was based on the Theory of Planned Behavior and the Health Belief Model and was empirically tested using cross-sectional survey data from Nanchong City, a city in western China, collected between October and December 2020. Data were analyzed using structural equation modeling.

Results

Behavioral intentions were the main predictor of medication adherence behavior (path coefficient of 0.353). Perceived benefits and perceived barriers directly (path coefficient = 0.201 and -0.150, respectively), and indirectly (path coefficient = 0.118 and -0.060) through behavioral intentions, influenced medication adherence behavior. Perceived susceptibility (path coefficient = 0.390) and perceived severity (path coefficient = 0.408) influenced behavioral attitudes, which influenced behavioral intentions (path coefficient = 0.298).

Conclusion

The conceptual model demonstrates a robust ability to predict and explain medication adherence behavior among elderly patients with hypertension, facilitating the adoption and maintenance of changes in adherence behavior and the potential for preventing disease progression and improving quality of life.

Factors influencing medication adherence in multi-ethnic Asian patients with chronic diseases in Singapore: A qualitative study

Background: Poor medication adherence can lead to adverse health outcomes and increased healthcare costs. Although reasons for medication adherence have been widely studied, less is explored about factors affecting medication adherence for patients in non-Western healthcare setting and from Asian cultures. This study aimed to explore cultural perspectives on factors influencing medication adherence among patients with chronic diseases in a multi-ethnic Asian healthcare setting.

Methods: We conducted a qualitative study involving in-depth interviews with patients with chronic conditions purposively recruited from a community hospital in Singapore until data saturation was achieved. A total of 25 patients participated in this study. Interviews were transcribed and thematically analyzed. Themes were subsequently mapped into the World Health Organization (WHO) Framework of Medication Adherence.

Results: Participants commonly perceived that sides effects (therapy-related dimension), poor understanding of medication (patient-related dimension), limited knowledge of condition (patient-related dimension), forgetfulness (patient-related dimension) and language issues within a multi-ethnic healthcare context (healthcare team and system-related dimension) as the main factors contributing to medication adherence. Importantly, medication adherence was influenced by cultural beliefs such as the notion of modern medicines as harms and fatalistic orientations towards escalation of doses and polypharmacy (patient-related dimension). Participants made various suggestions to foster adherence, including improved patient-physician communication, enhanced care coordination across providers, use of language familiar to patients, patient education and empowerment on the benefits of medication and medication adjustment.

Conclusion: A wide range of factors influenced medication adherence, with therapy- and patient-related dimensions more pronounced compared to other dimensions. Findings demonstrated the importance of cultural beliefs that may influence medication adherence. Future efforts to improve medication adherence should consider a person-centered approach to foster more positive health expectations and self-efficacy on medication adherence, supplemented with routine reviews, development of pictograms and cultural competence training for healthcare professionals.

Factors related to barriers and medication adherence in patients with type 2 diabetes mellitus: a cross-sectional study

Purpose

Evidence has shown that 50% of patients, including type 2 diabetes mellitus (DM), are non-adherent to the prescribed antidiabetic medication regimen. Some barriers lead to nonadherence in people with DM type 2. The study aimed to identify factors related to adherence in patient with DM and to assess the correlation between barriers to adherence type 2 DM patients.

Methods

The cross-sectional study was conducted in 63 primary healthcare centers in Surabaya, Indonesia. Patients with DM type 2 were recruited between April and September 2019 using convenient sampling technique. Ethics approval was obtained (80/EA/KEPK/2019).

Results

A total of 266 patients with type 2 DM participated in this study. Of the respondents, 201 (75.2%) were female. Unwanted drug effects, changes in medication regimens, and refilling the prescription when the drugs run out were most reported factors that affected adherence. Spearman correlations and linear regression tests were used to examine the relationship between barriers to medication adherence, and education with medication adherence. A significant difference was observed between the level of education and adherence (p = 0.031). The results showed an association between barriers to medication and adherence to medication (r = 0.304; p < 0.001) which was confirmed in regression analysis (R = 0.309, R square = 0.095, p <0.001).

Conclusions

Barriers to adherence are common and affect adherence to therapy. It is essential to expand the roles of health care professionals in the community to include counseling, barrier-monitoring, education, and problem-solving to improve patient medication adherence.

The Model Minority Myth, Data Aggregation, and the Role of Medical Schools in Combating Anti-Asian Sentiment

The COVID-19 pandemic has resulted in an alarming increase in hate incidents directed toward Asian Americans and Pacific Islanders (AAPIs), including verbal harassment and physical assault, spurring the nationwide #StopAsianHate movement. This rise in anti-Asian sentiment is occurring at a critical time of racial reckoning across the United States, galvanized by the Black Lives Matter movement, and of medical student calls for the implementation of antiracist medical curricula. AAPIs are stereotyped by the model minority myth, which posits that AAPIs are educated, hardworking, and therefore able to achieve high levels of success. This myth acts as a racial wedge between minorities and perpetuates harm that is pervasive throughout the field of medicine. Critically, the frequent aggregation of all AAPI subgroups as one monolithic community obfuscates socioeconomic and cultural differences across the AAPI diaspora while reinforcing the model minority myth. Here, the authors illustrate how the model minority myth and data aggregation have negatively affected the recruitment and advancement of diverse AAPI medical students, physicians, and faculty. Additionally, the authors discuss how data aggregation obscures health disparities across the AAPI diaspora and how the model minority myth influences the illness experiences of AAPI patients. Importantly, the authors outline specific actionable policies and reforms that medical schools can implement to combat anti-Asian sentiment and support the AAPI community.

Identifying temporal patterns of adherence to antidepressants, bisphosphonates and statins, and associated patient factors

Background

Group-based trajectory modelling (GBTM) has recently been explored internationally as an improved approach to measuring medication adherence (MA) by differentiating between alternative temporal patterns of nonadherence. To build on this international research, we use the method to identify temporal patterns of medication adherence to antidepressants, bisphosphonates or statins, and their associations with patient characteristics.

Objectives

The objectives include identification of MA types using GBTM, exploration of features and associated patient characteristics of each MA type, and identification of the advantages of GBTM compared to the traditional proportion of days covered (PDC) measure.

Data and methods

We used 45 and Up Study survey data which contains information about demographics, family, health, diet, work and lifestyle of 267,153 participants aged at least 45 years across New South Wales, Australia. This data was linked to participant records of medication use, outpatient and inpatient care, and death. Our study participants initiated use of antidepressants (9287 participants), bisphosphonates (1660 participants) or statins (10,242 participants) during 2012–2016. MA types were identified from 180-day patterns of medication use for antidepressants and 360-day patterns for bisphosphonates and statins. Multinomial and binomial logistic regressions were performed to estimate participant characteristics associated with GBTM MA and PDC MA, respectively.

Results

Three GBTM MA types were identified for antidepressants and six for bisphosphonates and statins. For all three medications, MA types included: almost fully adherent; decreasing adherence and early discontinuation. The additional nonadherent types for bisphosphonates and statins were improved adherence, low adherence and later discontinuation. Participant characteristics impacting GBTM MA and PDC MA were consistent. However, several associations were uniquely found for GBTM MA as compared to PDC MA.

Conclusion

GBTM permits clinicians, policy-makers and researchers to differentiate between alternative nonadherence patterns, allowing them to better identify patients at risk of poor adherence and tailor interventions accordingly.

•

Medication adherence was categorised using group-based trajectory modelling (GBTM).

•

GBTM categories include adherence, early discontinuation and decreasing adherence.

•

Demographic, economic, health and other factors determined GBTM categories.

•

GBTM provides additional information to better target adherence interventions.

Adherence to antihypertensive medications among adult hypertensive patients attending chronic follow-up units of Dessie Referral Hospital, Northeastern Ethiopia: A cross-sectional study

Hypertension is the leading cause of increased morbidity and mortality rates worldwide. Despite adherence to therapies is the important determinant of treatment success to reduce apparent resistant hypertension, maintaining good adherence to antihypertensive medications remained the most serious challenge. Thus, this study aimed to assess adherence to antihypertensive medications among adult hypertensive patients in Dessie Referral Hospital.A cross-sectional study design was conducted among hypertensive patients during May and June 2020. The study participants were selected using a systematic random sampling technique. The collected data were entered into EpiData version 4.4 and exported to SPSS version 25.0 software for data cleaning and analysis. Data were analyzed using bivariable and multivariable logistic regression at a 95% confidence interval (CI). A variable that has a P-value < .05 was declared as statistically significant. Hosmer-Lemeshow test was used to test goodness-of-fit and multicollinearity was tested.The overall good adherence to antihypertensive medications was 51.9%; 95% CI: (46.8-58.3%) and poor adherence was 48.1%. Factors associated with good adherence were: sex-female adjusted odd ratio (AOR) = 1.31; 95% CI (1.06-2.52), occupational status-employed AOR = 2.24; 95% CI (1.33-3.72), good knowledge of the disease AOR = 2.20; 95% CI (1.34-3.72) and good self-efficacy AOR = 1.38; 95% CI (1.20-2.13).This study revealed that almost half of the hypertensive patients in Dessie Referral Hospital had good antihypertensive medication adherence. Sex, occupational status, knowledge, and self-efficacy were factors associated with good adherence. Therefore, health education should be given to patients on the importance of complying with medication and patients should be monitored by health extension workers.

Development and validation of prescription drug risk, efficacy, and benefit perception measures in the context of direct-to-consumer prescription drug advertising

PURPOSE

Understanding patient perceptions of prescription drug risks and benefits is an important component of determining risk-benefit tradeoffs and helping patients make informed medication decisions. However, few validated measures exist for capturing such perceptions. The purpose of this study was to develop and validate measures of perception of prescription drug risk, efficacy, and benefit.

METHODS

We conducted a mixed-methods study to develop and validate the measures, including three waves of quantitative testing (item nonresponse, criterion-related validity, and convergent validity). We conducted quantitative testing with a probability-based online consumer panel of U.S. adults (n = 7635), eliminating weaker items after each testing wave.

RESULTS

Upon completion of all testing, we identified 21 validated measures that represent 11 distinct risk/benefit constructs. The final measures demonstrated face validity, convergent validity, criterion-related validity, and scale reliability in both illness and general population samples, among patients with both symptomatic and asymptomatic health conditions, and in response to both television and print direct-to-consumer prescription drug advertisements.

CONCLUSIONS

Our study produced a set of items that researchers and practitioners can use to assess patient perceptions of prescription drug risk, benefit, and efficacy and to ensure greater future comparability between studies.

Prevalence of non-adherence to antihypertensive medication in Asia: a systematic review and meta-analysis

Background Hypertension and its associated complications are one of the leading causes of morbidity and mortality in Asia. Racial disparities in terms of treatment outcomes among hypertension patients have been reported in literature with Asian patients resulting in poorer treatment outcomes. Non-adherence to antihypertensive therapy is frequently associated with poor treatment outcomes. Aim of the review The aim of this review was to estimate the prevalence of non-adherence to antihypertensive medications among patients with hypertension residing in Asia. Method PubMed, Google Scholar, MEDLINE, Embase, Scopus, CINHAL and Cochrane library were searched for studies published between 2000 and 2019 involving hypertensive patients. Studies investigating the prevalence of medication non-adherence in Asian countries, rated either good or fair on National Institute of Health quality assessment tool and published in English language were included in our review. Data were extracted by one author and checked by another using a structured and pilot-tested data extraction sheet. A random-effects meta-analysis was performed using STATA version 14.3®. Results Sixty-Six studies from 22 Asian countries including 2,532,582 hypertensive patients were included. Mean (± SD) age of participants was 58(± 6) years. Overall, the estimated prevalence of non-adherence to antihypertensive medication in Asia was 48% (95% CI: 41-54, P = 0.001). The rate of non-adherence was higher among females 49% (95% CI: 41-56, P = 0.001) compared to males 47% (95% CI: 40-53, P = 0.001). As per the region, the highest prevalence of non-adherence was found in South Asia 48% (95% 44-51, P = 0.877) followed by East Asia 45% (31-59, P = 0.001) and the Middle East 41 (95% 30-52, P = 0.001). Similarly, higher rate of non-adherence was observed in low and lower middle-income countries i.e. 50% (95% CI: 47-54, P = 0.220) as compare to upper-middle and high-income countries i.e. 37% (95% CI: 25-49, P = 0.001) and 44% (95% CI: 29-59, P = 0.001) respectively. Conclusion The prevalence of non-adherence to antihypertensive medication is high in Asia. This may partly explain poor treatment outcomes and incidence of higher mortality rate in Asia frequently reported in the literature. There is a need to implement appropriate policies and clinical practices to improve medication adherence.

Exploring Culture, Religiosity and Spirituality Influence on Antihypertensive Medication Adherence Among Specialised Population: A Qualitative Ethnographic Approach

BACKGROUND

Hypertension is one of the major risk factors of stroke and leading risk factors for global death. Inadequate control of blood pressure due to medication non-adherence remains a challenge and identifying the underlying causes will provide useful information to formulate suitable interventions.

PURPOSE

This study aimed to explore the roles of culture, religiosity, and spirituality on adherence to anti-hypertensive medications.

METHODOLOGY

A semi-structured qualitative interview was used to explore promoters and barriers to medication adherence among hypertensive individuals residing in urban and rural areas of Perak State, West Malaysia. Study participants were individuals who are able to comprehend either in Malay or English, above 18 years old and on antihypertensive medications. Interview transcriptions from 23 participants were coded inductively and analyzed thematically. Codes generated were verified by three co-investigators who were not involved in transcribing process. The codes were matched with quotations and categorized using three levels of themes named as organizing, classifying and general themes.

RESULTS

Cultural aspects categorized as societal and communication norms were related to non-adherence. The societal norms related to ignorance, belief in testimony and anything "natural is safe" affected medication adherence negatively. Communication norms manifested as superficiality, indirectness and non-confrontational were also linked to medication non-adherence. Internal and organizational religiosity was linked to increased motivation to take medication. In contrast, religious misconception about healing and treatment contributed towards medication non-adherence. The role of spirituality remains unclear and seemed to be understood as related to religiosity.

CONCLUSION

Culture and religiosity (C/R) are highly regarded in many societies and shaped people's health belief and behaviour. Identifying the elements and mechanism through which C/R impacted adherence would be useful to provide essential information for linking adherence assessment to the interventions that specifically address causes of medication non-adherence.

Association between attendance at outpatient follow-up appointments and blood pressure control among patients with hypertension

Objective

The aim of this study was to assess the impact of regularity in treatment follow-up appointments on treatment outcomes among hypertensive patients attending different healthcare settings in Islamabad, Pakistan. Additionally, factors associated with regularity in treatment follow-up were also identified.

Methods

A cross-sectional study was undertaken in selected primary, secondary and tertiary healthcare settings between September, 2017 and December, 2018 in Islamabad, Pakistan. A structured data collection form was used to gather sociodemographic and clinical data of recruited patients. Binary logistic regression analyses were undertaken to determine association between regularity in treatment follow-up appointments and blood pressure control and to determine covariates significantly associated with regularity in treatment follow-up appointments.

Results

A total of 662 patients with hypertension participated in the study. More than half 346 (52%) of the patients were females. The mean age of participants was 54 ± 12 years. Only 274 (41%) patients regularly attended treatment follow-up appointments. Regression analysis found that regular treatment follow-up was an independent predictor of controlled blood pressure (OR 1.561 [95% CI 1.102–2.211; P = 0.024]). Gender (OR 1.720 [95% CI 1.259–2.350; P = 0.001]), age (OR 1.462 [CI 95%:1.059–2.020; P = 0.021]), higher education (OR 1.7 [95% CI 1.041–2.778; P = 0.034]), entitlement to free medical care (OR 3.166 [95% CI 2.284–4.388; P = 0.0001]), treatment duration (OR 1.788 [95% CI 1.288–2.483; P = 0.001]), number of medications (OR 1.585 [95% CI 1.259–1.996; P = 0.0001]), presence of co-morbidity (OR 3.214 [95% CI 2.248–4.593; P = 0.0001]) and medication adherence (OR 6.231 [95% CI 4.264–9.106; P = 0.0001]) were significantly associated with regularity in treatment follow-up appointments.

Conclusion

Attendance at follow-up visits was alarmingly low among patients with hypertension in Pakistan which may explain poor treatment outcomes in patients. Evidence-based targeted interventions should be developed and implemented, considering local needs, to improve attendance at treatment follow-up appointments.

Assessment of patients' understanding of and adherence to oral anticancer medication (OAM): Results of a cross-sectional institutional pilot study

BACKGROUND

Although oral anticancer medications (OAM) provide opportunity for treatment at home, challenges include prescription filling, monitoring side effects, safe handling, and adherence. We assessed understanding of and adherence to OAM in vulnerable patients.

METHODS

This 2018 pilot study defined vulnerable patients based on Chinese language, older age (≥65 years), and subsidized insurance. All participants had a cancer diagnosis and were taking an OAM filled through the hospital's specialty pharmacy. Participants reported on OAM taking (days per week, times per day, special instructions) and handling (handling, storage, disposal). The specialty pharmacist classified patient-reported responses about OAM taking and handling as adequate or inadequate. OAM regimens were classified by complexity.

RESULTS

Of 61 eligible patients, 55 participated. Mean age was 68 years (standard deviation [SD] = 12) and 53% were female. Patient subgroups were: 27% Chinese, 64% ≥65 years, and 9% subsidized insurance. Forty-nine percent were on frontline therapy and median time on OAM was 1 year (Quartile 1 = 0.4, Quartile 3 = 1.7). Adequacy of OAM taking (30%) and handling (15%) were low; 15% had adequacy in both. Adequacy of OAM taking and handling did not vary by patient subgroup or regimen complexity. Mean patient-reported adherence was high (5.4, SD = 1, possible range 1-6) and did not vary by adequacy of OAM taking or handling.

CONCLUSIONS

Understanding of OAM taking and handling in this group of vulnerable patients was low and did not align with patient-reported adherence. Future interventions should ensure that patients understand how to safely take and handle OAM, thereby optimizing their therapeutic potential.

Prevalence and factors associated with adherence to anti-hypertensives among adults with hypertension in a developed Asian community: A cross-sectional study

Introduction:

Poor adherence to anti-hypertensive medications (AHM) results in hypertension treatment failure. Understanding and addressing the factors associated with adherence to AHM may potentially improve health outcomes. This study aimed to assess the prevalence and factors associated with patients’ adherence to AHM in a developed Asian community.

Methods:

An assistant-administered questionnaire survey was conducted on multi-ethnic Asian adults aged 31–80 years with essential hypertension based on their electronic health records (EHR) at a public primary-care clinic. Data on their demographic characteristics, clinical measurements of blood pressure and body mass index, co-morbidities and prescriptions from the EHR, along with the Medication Adherence Report Scale-5 scores were collated, audited and analysed. A MARS-5 score of <25 indicated poor adherence. Logistic regression was used to identify factors associated with adherence to AHM.

Results:

Data of 395 patients were analysed. Of these, 179 (45.3%) had poor adherence to at least one AHM. Bivariate analysis showed that poor adherence was significantly associated with lower mean age (59 years old vs. 63 years old), higher mean clinic diastolic blood pressure (76 mmHg vs. 73 mmHg) and higher mean weight (70.4 kg vs. 67.4 kg). Logistic regression showed that patients with no co-morbidities (such as diabetes mellitus, dyslipidaemia, stroke and ischaemic heart disease) had better medication adherence (MA; odds ratio=1.98; 95% confidence interval 1.14–3.45; p=0.02). There was no significant MA difference between the classes, dose frequency and number of AHM.

Conclusion:

Almost half of the patients had poor adherence to at least one AHM. Co-morbidity significantly influenced their MA. Attention should be directed to patients with co-morbidities to assess their AHM adherence.

Understanding Prevention and Management of Coronary Heart Disease Among Chinese Immigrants and Their Family Carers: A Socioecological Approach

Introduction: Health disparities among immigrants exist across socioecological domains. While Chinese immigrants face increased risk for coronary heart disease (CHD) after migration, the reasons are not well understood. Method: This descriptive qualitative study collected 18 semistructured interviews with Chinese immigrants with CHD and family carers from two Australian hospitals. Analysis was guided by the social–ecological model. Results: Poor knowledge and limited English proficiency increased CHD risk and difficulty navigating health care systems/resources. Interpersonal and family factors positively influenced health-seeking behaviors, acceptance of cardiac procedures, adoption of secondary preventive behaviors and information acquisition through social networks. A lack of culturally specific health information and programs in Chinese languages was described. Ethnic concordance between Chinese doctors and patients improved health literacy and engendered trust. Discussion: Culturally specific interventions could include health promotion materials in Chinese, inclusion of family in educational programs, and Chinese-focused public health campaigns about warning signs of heart attack.

Postoperative pain: factors and tools to improve pain management in children

Outpatient surgery has made it increasingly common for parents to manage pain in the home setting. Studies have shown that parents often under treat pain, leaving children vulnerable to the negative side effects of suboptimal pain management. Multiple factors affect pain management like child’s age and developmental stage, language, cultural values like stoicism, parental beliefs about medication, biological differences among groups, etc. Understanding all the factors involved can help healthcare providers and parents better understand pain and contribute to optimal pain management. Multiple tools and technological interventions have been created to help create a better understanding of pain and a holistic approach to care.

Health beliefs and medication adherence in patients with hypertension: A systematic review of quantitative studies

OBJECTIVE

This review synthesizes findings of quantitative studies examining the relationship between health beliefs and medication adherence in hypertension.

METHODS

This review included published studies in PubMed, CINHAL, EMBASE, and PsycINFO databases. Studies were included if they examined beliefs of patients with hypertension. Quality of the studies was evaluated using the Quality Assessment Tool for Systematic Review of Observational Studies.

RESULTS

Of the 1558 articles searched, 30 articles were included in the analysis. Most beliefs examined by studies of this review in relation to medication adherence were beliefs related to hypertension severity and susceptibility to its consequences, medication effectiveness or necessity, and barriers to medication adherence. Higher medication adherence was significantly related to fewer perceived barriers to adherence (e.g, side-effects) was fairly consistent across studies. Higher self-efficacy was related to higher medication adherence. Patients' beliefs and their relationship to medication adherence appear to vary unpredictably across and within countries.

CONCLUSION

Clinicians should assess beliefs for individual patients. When individual beliefs appear likely to undermine adherence, it may be useful to undertake educational interventions to try to modify them.

PRACTICAL IMPLICATIONS

Clinicians should explore individual patients' beliefs about hypertension and blood pressure medications, discuss their implications for medication adherence, and try to modify counterproductive beliefs.

Self-management and blood pressure control in China: a community-based multicentre cross-sectional study

OBJECTIVES

This study explored the relationship between self-management and blood pressure (BP) control in China.

DESIGN

A cross-sectional study.

SETTING

Eight community health centres from four cities in the Northeast (Shenyang), Northwest (Xi'an), Southwest (Chengdu) and South (Changsha) of China.

PARTICIPANTS

A total of 873 adults with hypertension, including 360 men and 513 women. Hypertension was defined as systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg.

OUTCOME MEASUREMENTS

BP control was the primary outcome variable. This was categorised as good control if individuals with hypertension reduced their BP to <140/90 mm Hg, otherwise, it was categorised as poor control. Secondary outcomes included self-management, defined as: (1) context or condition-specific factors or physical/social environments (eg, age, sex, marital status, education, personal income and health insurance) and (2) process or knowledge/beliefs, self-regulation skills/abilities and social facilitation (eg, treatment, diet, exercise and risk factor management). Data were analysed using logistic regression models using SPSS V.20.

RESULTS

A total of 67.1% (n=586) participants had poor BP control. Limited outpatient care benefits in mainly rural residents (OR 2.26, 95% CI 1.06 to 4.81) and longer disease duration (OR 1.03, 95% CI 1.01 to 1.04) were associated with poor BP control. Self-management practices reduced the odds of having poor BP control (OR 0.98, 95% CI 0.97 to 0.99).

CONCLUSIONS

The individual and family self-management theory can serve as an effective theory for understanding the key contexts, processes and outcomes essential for BP control in China. Future research should evaluate the effect of a self-management intervention (eg, self-monitoring, medication adherence, regular and routine doctor visits, and social supports) for BP control in China using a multisite cluster randomised controlled trial. Sex and gender difference, cost and patient-reported outcomes should also be examined.

Gender Based Cognitive Determinants Of Medication Adherence In Older Adults With Chronic Conditions

BACKGROUND

Life course gender-role traits and social stereotypes could affect the pattern of medication adherence in old age.

OBJECTIVES

The main purpose of this study was to investigate gender based cognitive determinants of medication adherence in a sample of older adults who suffer from at least a chronic condition.

METHODS

In this cross-sectional design, 455 older adults participated from five health centers in Tabriz city, Iran from June to August 2017 using a random sampling method. Next, required data about medication adherence, knowledge and beliefs about prescribed medications, perceived self-efficacy in medication adherence, illness perception, and reasons for medication non-adherence were gathered using a structured written questionnaire through face-to-face interviews with the attendees.

RESULTS

Low medication adherence was reported by 54.5% of the study participants. Perceived self-efficacy for medication adherence (OR = 1.04; 95% CI: 1.00, 1.08) and medication adherence reason (OR = 0.96; 95% CI: 0.92, 0.99) were two identified strong predictors of medication adherence among the studied older men. Illness perception (OR = 1.02; 95% CI: 1.00, 1.02) and beliefs toward prescribed medication (OR = 0.95; 95% CI: 0.93, 0.98) were both recognized as the significant predictors of medication adherence in the older women subgroup.

CONCLUSION

Gender based variations were noted regarding the medication adherence in the studied sample and attributes of cognitive function were the main pinpointed elucidating parameters for the non-conformity. The explicit cognitive processes must be considered in care provision or interventional programs that target medication adherence in older adults.

Conceptual Model of Medication Adherence in Older Adults with High Blood Pressure-An Integrative Review of the Literature

BACKGROUND

Medication adherence (MA) is the most important controlling factor of high blood pressure (HBP). There are a few MA models, but they have not been successful in predicting MA completely. Thus, this study aimed to expand a conceptual model of MA based on an ecological approach.

METHODS

An integrative review of the literature based on theoretical and empirical studies was completed. Data source comprised: Medline (including PubMed and Ovid), ISI, Embase, Google scholar, and internal databases such as Magiran, Google, SID, and internal magazines. Primary English and Persian language studies were collected from 1940 to 2018. The steps of study included: (a) problem identification, (b) literature review and extracting studies, (c) appraising study quality, (d) gathering data, (e) data analysis using the directed content analysis, (f) concluding.

RESULTS

Thirty-six articles were finally included and analyzed. After analysis, predictors of MA in older adults with hypertension were categorized into personal, interpersonal, organizational, and social factors. Although the personal factors have the most predictors in sub-categories of behavioral, biological, psychological, knowledge, disease, and medication agents, social, organizational and interpersonal factors can have indirect and important effects on elderly MA.

CONCLUSION

There are many factors influencing MA of elderly with HBP. The personal factor has the most predictors. The designed model of MA because of covering all predictor factors, can be considered as a comprehensive MA model. It is suggested that future studies should select factors for study from all levels of the model.

A Novel mHealth Approach for a Patient-Centered Medication and Health Management System in Taiwan: Pilot Study

Background

Mobile health (mHealth) apps have recently demonstrated the potential to engage and empower people to improve their own health. Although the availability of health-related apps is increasing, their adoption rate in Taiwan is exceptionally low mainly due to the preponderance of Western culture-based app designs that are challenging for non-English-speaking individuals. To our knowledge, no mHealth app is available in Taiwan that is culturally tailored for Chinese-speaking users and that applies a patient-centered approach to self-manage medication and health.

Objective

The purpose of this study was to design and deploy a culturally tailored mHealth system that could be easily integrated into current clinical practice and to evaluate how this mHealth system could support the continuity of patient care in Taiwan.

Methods

An mHealth information system and a mobile app were designed. To promote the best patient experience, a Quick Response (QR) code system was developed to enable efficient registration of personal medication information through the mobile app. The app also supported notifications for drug utilization, refills, and symptom checks. Patients were encouraged to record medication use, symptoms, and self-assessments in the app during their treatment period. Evaluation of the novel mHealth system was conducted from August 1, 2016 to December 31, 2016 at MacKay Memorial Hospital, Taipei, Taiwan. Population data and app usage statistics were analyzed.

Results

During the 5-month implementation period, a total of 25,909 users downloaded the app with an overall 7-day retention rate of 15.4% (SD 3.9). Young male adults (range 25-44 years) were the predominant user population. Patients’ feedback on app usability and design, QR code system as drug input method, medication reminders, and linking family or friends into care networks was generally positive. Physicians showed great interest in utilizing patient-generated data in their care process, and the positive medication adherence rate was the most highly valued component of this system.

Conclusions

This pilot study demonstrated the value of a novel mHealth approach for individualized medication and health management in Taiwan. The mHealth system shows the potential to optimize personalized care into existing clinical services and may help hospitals and health authorities perform continuous quality improvement and policy development.

Diet and Blood Pressure Control in Chinese Canadians: Cultural Considerations

Hypertension is highly prevalent in Chinese Canadians and diet has been identified as an important modifiable risk factor for hypertension. The current anti-hypertensive dietary recommendations in hypertension care guidelines lack examination of cultural factors, are not culturally sensitive to ethnic populations, and cannot be translated to Chinese Canadian populations without cultural considerations. Guided by Leininger's Sunrise Model of culture care theory, this paper investigates how cultural factors impact Chinese Canadians' dietary practice. It is proposed that English language proficiency, health literacy, traditional Chinese diet, migration and acculturation, and Traditional Chinese Medicine influence Chinese Canadians' dietary practices. A culturally congruent nursing intervention should be established and tailored according to related cultural factors to facilitate Chinese Canadians' blood pressure control. In addition, further study is needed to test the model adapted from Sunrise Model and understand its mechanism.

Is There Disparity in Cardiovascular Health Between Migrant Workers and Native Workers?

The purpose of this study was to identify the probability of developing cardiovascular disease (CVD) and its association with metabolic syndrome (MS) risk factors among middle-aged Korean Chinese (KC) migrant women workers compared to comparable native Korean (NK) women workers. Using matched samples based on the propensity score matching method, 10-year CVD risk was calculated and MS risk factors identified. Logistic regression and classification and regression tree (CART) analysis were conducted. The probability of KC migrants' 10-year CVD risk was significantly lower (6.4%) than NK women risk (7.8%, t = 1.99, p = .048). Blood pressure of 130/85 mmHg or higher was found to be a significant risk factor for 10-year CVD risk in both groups. The findings support existing knowledge about the healthy immigrant effect on CVD and MS risk factors. The findings could be the basis for occupational health professionals to pursue policy initiatives and public health and occupational health interventions to improve CVD outcomes among migrant women workers including KC migrants.

Cardiovascular diseases and risk factors among Chinese immigrants

The aim of this study is to identify the prevalence of cardiovascular disease (CVD) and major CVD risk factors, including diabetes, hypertension, dyslipidemia, obesity and smoking among Chinese immigrants by a systematic review of studies from various countries. PubMed and the China National Knowledge Infrastructure databases were searched for studies of the prevalence of major CVDs and risk factors, and of CVD mortality among Chinese immigrants. The search identified 386 papers, 16 of which met the inclusion criteria for this review. In mainland China, there is a pattern of high stroke prevalence but low coronary heart disease (CHD) prevalence. Among Chinese immigrants, there is a much lower prevalence and mortality of stroke, but a higher prevalence and mortality of CHD, even though these are lower than the rates in immigrants of other ethnicities in the host country. The prevalence of CVD risk factors is also markedly different in immigrants. Compared with mainland Chinese, Chinese immigrants have a higher prevalence of diabetes and hypertension, higher serum cholesterol, poorer dietary patterns, and higher prevalence of obesity and smoking. Thus, the epidemiological pattern of CVD among Chinese immigrants changes compared with resident mainland Chinese. The less healthy environmental factor after immigration may be a major trigger in the adverse CVD status of Chinese immigrants. It is important for policy-makers to pay more attention to specific minority immigrant groups, and to implement more effective preventive measures to improve the health of immigrant populations.

A Chinese Immigrant Paradox? Low Coronary Heart Disease Incidence but Higher Short-Term Mortality in Western-Dwelling Chinese Immigrants: A Systematic Review and Meta-Analysis

BACKGROUND

Chinese form a large proportion of the immigrant population in Western countries. There is evidence that Chinese immigrants experience an increased risk of coronary heart disease (CHD) after immigration in part due to cultural habits and acculturation. This is the first systematic review and meta-analysis that aims to examine the risk of CHD in people of Chinese ethnicity living in Western countries, in comparison with whites and another major immigrant group, South Asians.

METHODS AND RESULTS

Literature on the incidence, mortality, and prognosis of CHD among Chinese living in Western countries was searched systematically in any language using 6 electronic databases up to December 2014. Based on the meta-analysis, Chinese had lower incidence of CHD compared with whites (odds ratio 0.29; 95% CI: 0.24-0.34) and South Asians (odds ratio 0.37; 95% CI: 0.24-0.57) but higher short-term mortality after first hospitalization for acute myocardial infarction compared with whites (odds ratio 1.34; 95% CI, 1.04-1.73) and South Asians (odds ratio 1.82; 95% 1.33-2.50). There was no significant difference between Chinese immigrants and whites in long-term outcomes (mortality and recurrent events) after acute myocardial infarction.

CONCLUSIONS

These findings provide an important focus for resource planning to enhance early secondary prevention of CHD to improve short-term survival outcomes among Western-dwelling Chinese immigrants.

Systematic review of the barriers affecting medication adherence in older adults

Medication adherence is a crucial part in the management of chronic diseases. As older adults form a greater proportion of the population with chronic diseases and multiple morbidities, understanding medication adherence in older adults becomes important. In the present article, we aimed to systematically review the literature for the factors associated with medication adherence in the geriatric population. We carried out a literature search using electronic databases and related keywords. 17 391 articles were reviewed in total. 65 articles were found to be relevant to our objective. A total of 80 factors of five different categories were found to be associated with medication adherence in older adults. The factors, the types of studies and the number of studies that agreed or disagreed were presented. A flower model for medication adherence was also presented to allow clinicians to better understand the complex nature of medication adherence in this population. The 80 factors reviewed were categorized into five main categories; namely, patient factors, medication factors, physician factors, system-based factors and other factors as factors affecting poor medication adherence in older adults. Clinicians need to be mindful of the complex nature of factors affecting medication adherence in this population to optimize therapeutic outcomes. Clinicians have to be more skillful to discover and to optimize the medication adherence factors in geriatric patients. The flower model is presented as a framework for clinicians to better understand the various factors affecting medication adherence in older adults. Geriatr Gerontol Int 2016; 16: 1093-1101.

Prevalence, prescribing and barriers to effective management of hypertension in older populations: a narrative review

Objectives

Hypertension is the leading modifiable cause of mortality worldwide. Unlike many conditions where limited evidence exists for management of older individuals, multiple large, robust trials have provided a solid evidence-base regarding the management of hypertension in older adults. Understanding the impact of age on how the prevalence of hypertension and the role of pharmacotherapy in managing hypertension among older persons is a critical element is the provision of optimal health care for older populations. The aim of this study was to explore how the prevalence of hypertension changes with age, the evidence regarding pharmacological management in older adults and to identify known barriers to the optimal management of hypertension in older patients.

Methods

A review of English language studies published prior to 2013 in Medline, Embase and Google scholar was conducted. Key search terms included hypertension, pharmacotherapy, and aged.

Results

The prevalence of hypertension was shown to increase with age, however there is good evidence for the use of a number of pharmacological agents to control blood pressure in older populations. System, physician and patient related barriers to optimal blood pressure control were identified.

Conclusions

Despite good evidence for pharmacological management of hypertension among olderpopulations, under treatment of hypertension is an issue. Concerns regarding adverse effects appearcentral to under treatment of hypertension among older populations.

Cultural Beliefs Underlying Medication Adherence in People of Chinese Descent in the United States

This article examines the meanings, practices, and cultural beliefs underlying medication adherence in people of Chinese descent living in the United States. The narratives were analyzed using interpretive phenomenology, resulting in the following themes that influenced the communication and behaviors around medication adherence of the participants: (a) cultural concepts of yin yang balance and "qi," (b) understandings of Western and Chinese medicine's efficacy profiles, (c) importance of family and social support, and (d) level of acculturation. This article discusses the influence of these themes on medication adherence and proposes that health communication campaigns, interventions, and doctor-patient communication about increasing medication adherence with people of Chinese descent should engage these understandings.

Patient and healthcare provider barriers to hypertension awareness, treatment and follow up: a systematic review and meta-analysis of qualitative and quantitative studies

Background

Although the importance of detecting, treating, and controlling hypertension has been recognized for decades, the majority of patients with hypertension remain uncontrolled. The path from evidence to practice contains many potential barriers, but their role has not been reviewed systematically. This review aimed to synthesize and identify important barriers to hypertension control as reported by patients and healthcare providers.

Methods

Electronic databases MEDLINE, EMBASE and Global Health were searched systematically up to February 2013. Two reviewers independently selected eligible studies. Two reviewers categorized barriers based on a theoretical framework of behavior change. The theoretical framework suggests that a change in behavior requires a strong commitment to change [intention], the necessary skills and abilities to adopt the behavior [capability], and an absence of health system and support constraints.

Findings

Twenty-five qualitative studies and 44 quantitative studies met the inclusion criteria. In qualitative studies, health system barriers were most commonly discussed in studies of patients and health care providers. Quantitative studies identified disagreement with clinical recommendations as the most common barrier among health care providers. Quantitative studies of patients yielded different results: lack of knowledge was the most common barrier to hypertension awareness. Stress, anxiety and depression were most commonly reported as barriers that hindered or delayed adoption of a healthier lifestyle. In terms of hypertension treatment adherence, patients mostly reported forgetting to take their medication. Finally, priority setting barriers were most commonly reported by patients in terms of following up with their health care providers.

Conclusions

This review identified a wide range of barriers facing patients and health care providers pursuing hypertension control, indicating the need for targeted multi-faceted interventions. More methodologically rigorous studies that encompass the range of barriers and that include low- and middle-income countries are required in order to inform policies to improve hypertension control.

[Evaluation of a medication self-management education program for elders with hypertension living in the community]

PURPOSE

The purpose of this study was to examine the effect of a medication self-management education program on medication awareness, communication with health care provider, medication misuse behavior, and blood pressure in elders with hypertension.

METHODS

The research design for this study was a non-equivalent control group quasi-experimental design. Participants were 23 elders for the control group, and 26 elders for the experimental group. The experimental group participated in the medication self-management education program which included the following, verbal education, 1:1 consultation, practice in medication self-management, and discussion over 5 sessions. Data were analyzed using the SPSS 18.0 program.

RESULTS

There were statistically significant differences between the experimental and control group for medication awareness, medication misuse behavior, and communication with health care providers. However, no significant difference was found between the two groups for blood pressure.

CONCLUSION

The results indicate that the education program is effective in improving medication awareness and communication with health care providers and in decreasing medication misuse behavior. Therefore, it is recommended that this education program be used as an effective intervention for improving medication self-management for elders with hypertension.

Correlates of Health-Related Quality of Life Among Korean Immigrant Elders

Health-related quality of life (HRQOL) is a key clinical outcome, particularly for individuals with chronic conditions such as hypertension (HTN). While no previous research has examined contributors to HRQOL among Asian Americans in the United States, this study was conducted to identify correlates of HRQOL in hypertensive Korean immigrant elders (≥ 60 years of age) to address the gap. A total of 440 Korean elders with HTN participated in the study. The hierarchical regression model for HRQOL explained 32.8% of the variance. Female gender (β = .109, p = .036), a greater number of comorbid conditions (β = .183, p = .000), lower social support (β = -.240, p = .000), and greater depressive symptoms (β = .402, p = .000) were associated with poorer HRQOL. Depression was the most potent correlate of HRQOL among elderly Korean Americans (KA) with HTN. Future intervention should consider managing depression as an essential component of comprehensive HTN care for this minority population.

A systematic review of patient self-reported barriers of adherence to antihypertensive medications using the world health organization multidimensional adherence model

Multiple barriers can influence adherence to antihypertensive medications. The aim of this systematic review was to determine what adherence barriers were included in each instrument and to describe the psychometric properties of the identified surveys. Barriers were characterized using the World Health Organization (WHO) Multidimensional Adherence Model with patient, condition, therapy, socioeconomic, and health care system/team-related barriers. Five databases (Medline, Embase, Health and Psychological Instruments, CINHAL, and International Pharmaceutical Abstracts [IPA]) were searched from 1980 to September 2011. Our search identified 1712 citations; 74 articles met inclusion criteria and 51 unique surveys were identified. The Morisky Medication Adherence Scale was the most commonly used survey. Only 20 surveys (39%) have established reliability and validity evidence. According to the WHO Adherence Model domains, patient-related barriers were most commonly addressed, while condition, therapy, and socioeconomic barriers were underrepresented. The complexity of adherence behavior requires robust self-report measurements and the inclusion of barriers relevant to each unique patient population and intervention.

Drug adherence and the incidence of coronary heart disease- and stroke-specific mortality among 218,047 patients newly prescribed an antihypertensive medication: a five-year cohort study

Background

Randomized trials have shown that optimal adherence to antihypertensive agents could protect against cardiovascular diseases, but whether adherence reduces cardiovascular deaths in community settings has not been explored so fully. This study evaluates the association between antihypertensive adherence and cardiovascular (coronary heart disease and stroke) mortality in the primary care settings.

Methods

From a territory-wide database in Hong Kong, we included all patients who were prescribed their first-ever antihypertensive agents in the years between 2001 and 2005 from the public healthcare sector. All patients were followed up for five years, and assigned as having poor (Proportion of Days Covered [PDC] < 40%), intermediate (40–79%), and high (≥ 80%) adherence to antihypertensive agents. The association between antihypertensive adherence and cardiovascular mortality was evaluated by using the Cox proportional hazard models.

Results

From a total of 218,047 eligible patients, 3825 patients (1.75%) died of cardiovascular disease within five years after having received their first-ever antihypertensive agents. The proportions of patients having poor, intermediate, and high medication adherence were 32.9%, 12.1%, and 55.0%, respectively. Higher adherence levels at PDC 40%–79% (HR = 0.46, 95% C.I. 0.41–0.52, p < 0.001) and ≥ 80% (HR = 0.91, 95% C.I. 0.85–0.98, p = 0.012) were significantly less likely to be associated with mortality than the poor adherence (PDC0.040) group.

Conclusions

Better antihypertensive adherence was associated with lower cardiovascular mortality. This highlights the need to promote adherence through strategies which have been proved to be effective in clinical settings.
