Treatment adherence among adult hypertensive patients: a cross-sectional retrospective study in primary care in Romania

Reimagining Medication Adherence: A Novel Holistic Model for Hypertension Therapy

Purpose

Patients' adherence to the prescribed therapy is influenced by several personal and social factors. However, existing studies have mostly focused on individual aspects. We took a holistic approach to develop a higher-level impact factor model.

Patients and Methods

In this independent, non-interventional, cross-sectional and anonymous study design the pharmacist recruited patients who entered the pharmacy and handed in a prescription for a blood pressure medication. The patients received a paper questionnaire with a stamped return envelope to volunteer participation. A total of 476 patients in Germany who reported having at least high normal blood pressure according to the Global Hypertension Practice Guidelines were surveyed. In this study, each patient received an average of 2.49 antihypertensive prescriptions and 7.9% of all patients received a fixed-dose combination. Partial least squares structural equation modeling was performed for model analytics since it enables robust analysis of complex relationships.

Results

Emotional attitude, behavioral control, and therapy satisfaction directly explained 65% of therapy adherence. The predictive power of the out-of-sample model for the Q2-statistic was significant. The patient's overall therapy satisfaction determined medication adherence. The medication scheme's complexity also influenced the adherence levels. Therapy satisfaction was significantly shaped by the complexity of the medication scheme, behavioral control, and emotional attitude. The results demonstrated the superior performance of fixed-dose combinations against combinations of mono-agents according to the adherence level. Additionally, patient-physician and patient-pharmacist relationships influenced behavioral control of medication therapy execution. According to the A14-scale to measure the level of adherence, 49.6% of patients were classified as adherent and the remainder as non-adherent.

Conclusion

The results enable healthcare stakeholders to target attractive variables for intervention to achieve maximum effectiveness. Moreover, the proven predictive power of the model framework enables clinicians to make predictions about the adherence levels of their hypertensive patients.

Automatic Detection and Classification of Hypertensive Retinopathy with Improved Convolution Neural Network and Improved SVM

Hypertensive retinopathy (HR) results from the microvascular retinal changes triggered by hypertension, which is the most common leading cause of preventable blindness worldwide. Therefore, it is necessary to develop an automated system for HR detection and evaluation using retinal images. We aimed to propose an automated approach to identify and categorize the various degrees of HR severity. A new network called the spatial convolution module (SCM) combines cross-channel and spatial information, and the convolution operations extract helpful features. The present model is evaluated using publicly accessible datasets ODIR, INSPIREVR, and VICAVR. We applied the augmentation to artificially increase the dataset of 1200 fundus images. The different HR severity levels of normal, mild, moderate, severe, and malignant are finally classified with the reduced time when compared to the existing models because in the proposed model, convolutional layers run only once on the input fundus images, which leads to a speedup and reduces the processing time in detecting the abnormalities in the vascular structure. According to the findings, the improved SVM had the highest detection and classification accuracy rate in the vessel classification with an accuracy of 98.99% and completed the task in 160.4 s. The ten-fold classification achieved the highest accuracy of 98.99%, i.e., 0.27 higher than the five-fold classification accuracy and the improved KNN classifier achieved an accuracy of 98.72%. When computation efficiency is a priority, the proposed model's ability to quickly recognize different HR severity levels is significant.

Non-compliance with medical recommendations results in delayed hospitalization and poorer prognosis in patients with cerebral ischemic stroke in Poland: Non-compliance effects on post-ischemic stroke prognosis

OBJECTIVES

This study aimed to reveal and analyze the causes of delays in reaching the hospital of patients with cerebral ischemic stroke and to assess their clinical picture.

MATERIAL AND METHODS

The study group included 161 patients with stroke, who reported to the hospital beyond the thrombolytic treatment therapeutic window. The control group consisted of 85 patients recruited consecutively with stroke who received thrombolytic treatment per eligibility criteria. Laboratory and medical imaging tests essential for neurological condition assessment were conducted in the study group. Control group research was based on retrospective analysis of medical records.

RESULTS

The rate of deaths during hospitalization was lower in the control group (4.7%) compared to the study group (14.9%). In the study group, more patients (16.8%) admitted to non-compliance with medical recommendations than in the control group (5.9%). There were no statistically significant differences in nicotinism and alcohol dependence syndrome frequency between both groups.

CONCLUSIONS

Based on each group inclusion criteria, a lower mortality rate in the control group indicates a crucial role of the therapeutic window in cerebral stroke treatment. Analysis of reasons for delay points out that efficient prophylaxis is the education of patients with stroke risk factors and their families.

Design and development of a smartphone app for hypertension management: An intervention mapping approach

Background

Several research studies have demonstrated the potential of mobile health apps in supporting health management. However, the design and development process of these apps are rarely presented.

Objective

We present the design and development of a smartphone-based lifestyle app integrating a wearable device for hypertension management.

Methods

We used an intervention mapping approach for the development of theory- and evidence-based intervention in hypertension management. This consisted of six fundamental steps: needs assessment, matrices, theoretical methods and practical strategies, program design, adoption and implementation plan, and evaluation plan. To design the contents of the intervention, we performed a literature review to determine the preferences of people with hypertension (Step 1) and necessary objectives toward the promotion of self-management behaviors (Step 2). Based on these findings, we implemented theoretical and practical strategies in consultation with stakeholders and researchers (Steps 3), which was used to identify the functionality and develop an mHealth app (Step 4). The adoption (Step 5) and evaluation (Step 6) of the mHealth app will be conducted in a future study.

Results

Through the needs analysis, we identified that people with hypertension preferred having education, medication or treatment adherence, lifestyle modification, alcohol and smoking cessation and blood pressure monitoring support. We utilized MoSCoW analysis to consider four key elements, i.e., education, medication or treatment adherence, lifestyle modification and blood pressure support based on past experiences, and its potential benefits in hypertension management. Theoretical models such as (i) the information, motivation, and behavior skills model, and (ii) the patient health engagement model was implemented in the intervention development to ensure positive engagement and health behavior. Our app provides health education to people with hypertension related to their condition, while utilizing wearable devices to promote lifestyle modification and blood pressure management. The app also contains a clinician portal with rules and medication lists titrated by the clinician to ensure treatment adherence, with regular push notifications to prompt behavioral change. In addition, the app data can be reviewed by patients and clinicians as needed.

Conclusions

This is the first study describing the design and development of an app that integrates a wearable blood pressure device and provides lifestyle support and hypertension management. Our theory-driven intervention for hypertension management is founded on the critical needs of people with hypertension to ensure treatment adherence and supports medication review and titration by clinicians. The intervention will be clinically evaluated in future studies to determine its effectiveness and usability.

Relationship between Nutrition, Lifestyle Habits and Laboratory Parameters in Hypertensive Patients with/without Cognitive Dysfunction

(1) Background: Cognitive dysfunction is a major concern in hypertensive patients. Lifestyle habits and nutrition influence laboratory parameters, with an impact on clinical course. The objective of the study was to evaluate nutrition and lifestyle habits in hypertensive patients with/without cognitive dysfunction and establish correlations to laboratory parameters.

MATERIAL AND METHODS

50 patients admitted to the Cardiovascular Rehabilitation Clinic in Târgu Mureș were enrolled in this study between March-June 2021. We evaluated their cognitive function, and they filled in a questionnaire about lifestyle and nutrition. Biochemical blood tests were performed using a Konelab Prime 60i analyzer. IBM-SPSS22 and GraphPad InStat3 were used for statistics.

RESULTS

Mean age of hypertensive patients (n = 50) was 70.42 ± 4.82 (SD) years, half of them had cognitive dysfunction. Zinc deficiency was present in 74% of the subjects. The subgroup with cognitive dysfunction had significantly higher BMI (p = 0.009) and microalbuminuria (p = 0.0479), as well as significantly lower magnesium intake (p = 0.032) and cholesterol intake (p = 0.022), compared to those with normal cognitive status.

CONCLUSIONS

Nutrition is in a close relationship with laboratory parameters; significant differences (microalbuminuria, cholesterol intake, BMI, etc.) are present between hypertensive patients with/without cognitive dysfunction. A healthy diet is important for the maintenance of metabolic balance, the achievement of optimal body weight, and the prevention of complications.

Factors related to treatment adherence among hypertensive patients: A cross-sectional study in primary healthcare centers in Taif city

BACKGROUND

Antihypertensive medications must be taken as prescribed since noncompliance can result in the lack of hypertension (HTN) control. The aim of this study was to determine the factors that influence adherence to treatment by HTN patients in Taif city.

MATERIALS AND METHODS

A cross-sectional study was undertaken in basic healthcare centers in Taif city, Saudi Arabia. A simple random sampling method was used to select participants from primary healthcare centers. Data was obtained on patients' demographic characteristics, smoking habits, anti-HTN drugs and treatment characteristics, barriers to medication compliance, systolic and diastolic blood pressure (BP), anthropometric measurements, and family history of HTN and diabetes mellitus (DM). We used the 4-item Morisky Medication Adherence Scale (MMAS-4™) as a valid questionnaire to assess medication adherence. Data were analyzed using SPSS. Qualitative data was presented as numbers and percentages, and Chi-squared test was applied to test the relationship between qualitative variables. For quantitative data, mean and standard deviation was calculated. Multiple logistic regression analysis were performed to determine correlates of treatment adherence, and results were presented as Odds Ratio (OR) and 95% confidence interval (CI) for OR.

RESULTS

Of the 549 patients included, 36.8% did not have a regular check of their BP at home and the majority had a family history of HTN and diabetes. About 86% patients showed a high level of adherence. Income ≥5000 SAR, age ≥60 years, female gender, who were being married, having ≤10 family members, being unemployed, and never having smoked were associated with high adherence level. The most important factor that affected MMAS scores was the regular BP checks at home.

CONCLUSION

When patients attend routine follow-up clinics, it is critical to strengthen reminder mechanisms and provide regular counseling.

Measuring medication adherence of hypertensive patients with monotherapy treatment in a community health center by utilizing medication possession ratio

Adherence is a particular concern in treating hypertension, and non-adherence to antihypertensive drugs might cause uncontrolled hypertension. This study aimed to measure retrospectively the medication adherence of hypertensive patients with monotherapy treatment in a community health center (Puskesmas) in Bandung city, Indonesia. The retrospective patient data from 2011 to 2015 were obtained from an electronic prescription database. The patient data of those diagnosed with hypertension, >18 years old, and who received mono-antihypertensive therapy within a 12-month period were included in this study. To assess medication adherence, the medication possession ratio (MPR) was applied. Out of 780 patients, 93.6% of patients showed poor adherence, about 5.8% showed intermediate adherence, and 0.6% of patients had high adherence. Males and females showed different levels of adherence (p<0.05). Efforts should be focused on obtaining optimum clinical benefits and strengthening the effectiveness of health systems in Indonesia.

Translation, Cultural Adaptation and Validation of the Hill Bone Compliance to High Blood Pressure Therapy Scale to Nepalese Language

BACKGROUND

Control of high blood pressure and prevention of cardiovascular complications among hypertensive patients depends on patients' adherence to therapy. The Hill-Bone Compliance to High Blood Pressure Therapy Scale (HBCTS) is one of the most popular scale to assess hypertensive patients' adherence behaviour. Unfortunately, no questionnaire in the Nepalese language is available to date to assess adherence to anti-hypertensive therapy.

AIM

To translate, culturally adapt and validate the English original version of the HBCTS into Nepalese language to measure treatment adherence of Nepalese hypertensive patients.

METHODS

The cross-sectional study was conducted to translate, culturally adapt and validate the HBCTS into Nepalese version. The standard translation process was followed and was evaluated among 282 hypertensive patients visiting selected primary healthcare centers (PHCCs) of Kathmandu district, Nepal. Cronbach's alpha was measured to assess the reliability of the tool. Exploratory factor analysis using principal component analysis with varimax rotation was used to evaluate structural validity.

RESULTS

The mean±SD age of 282 participants was 58.49±12.44 years. Majority of participants were literate (75.2%), and consumed at least one anti-hypertensive medication per day (85.5%). Nearly half (42.2%) of the participants had a family history of hypertension, and almost half (48%) of them had comorbid conditions. Mean ±SD score for overall adherence was 17.85±3.87 while those of medication taking, reduced salt taking, and appointment keeping subscales were 10.63±2.55, 4.16±1.12 and 3.06±1.07, respectively. Kaiser Meyer Olkin (KMO) was found to be 0.877. Exploratory factor analysis revealed a three-component structure; however, the loading of components into medication adherence, reduced salt intake and appointment keeping constructs were not identical to the original tool. Cronbach's alpha score for the entire HBCTS scale was 0.846.

CONCLUSION

The translated Nepali version of the HBCTS demonstrated acceptable reliability and validity to measure adherence to antihypertensive therapy among hypertensive patients in clinical and community settings in Nepal.

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.

Prescription Habits Related to Chronic Pathologies of Elderly People in Primary Care in the Western Part of Romania: Current Practices, International Recommendations, and Future Perspectives Regarding the Overuse and Misuse of Medicines

The European Commission’s 2019 report regarding the state of health profiles highlighted the fact that Romania is among the countries with the lowest life expectancy in the European Union. Therefore, the objectives of the present study were to assess the current prescription habits of general physicians in Romania related to medicines taken by the elderly population for chronic conditions in both urban and rural setting and to discuss/compare these practices with the current international recommendations for the elderly (American—Beers 2019 criteria and European—STOPP/START v.2, 2015 criteria). A total of 2790 electronic prescriptions for chronic pathologies collected from 18 community pharmacies in the western part of Romania (urban and rural zones) were included. All medicines had been prescribed by general physicians. We identified the following situations of medicine overuse: 15% of the analyzed prescriptions involved the use of nonsteroidal anti-inflammatory drugs (NSAIDs) for >2 weeks, 12% involved the use of a proton-pump inhibitor (PPI) for >8 weeks, theophylline was the bronchodilator used as a monotherapy in 3.17% of chronic obstructive pulmonary disease cases, and zopiclone was the hypnotic drug of choice for 2.31% of cases. Regarding the misuse of medicines, 2.33% of analyzed prescriptions contained an angiotensin-converting enzyme (ACE) inhibitor and an angiotensin II receptor blocker (ARB) for patients with renal failure in addition to vitamin K antagonists (AVKs) and NSAIDs in 0.43% of cases. Prescriptions for COX2 NSAIDs for periods longer than 2 weeks for patients with cardiovascular disorders accounted for 1.33% of prescriptions, and trihexyphenidyl was used as a monotherapy for patients with Parkinson’s disease in 0.18% of cases. From the included medical prescriptions, 32.40% (the major percent of 2383 prescriptions) had two potentially inappropriate medications (PIMs). Rural zones were found to be risk factor for PIMs. Decreasing the chronic prescription of NSAIDs and PPIs, discontinuing the use of hypnotic drugs, and avoiding potentially harmful drug–drug associations will have long term beneficial effects for Romanian elderly patients.

Relationship between beliefs about medicines and adherence in elderly patients with cardiovascular and respiratory diseases: A cross-sectional study in Romania

OBJECTIVES

The aim of this study was to explore elderly patients' beliefs about medicines in general, and specific towards their treatment and the relationship between beliefs and adherence.

METHODS

A cross-sectional study was performed by administering a questionnaire developed to meet the study's objectives. Elderly patients were recruited from three different settings.

RESULTS

167 patients agreed to participate to our study, having a mean age of 73 years. Patients were aware of the necessity for treatment, but they also showed concern over the potential for the adverse outcomes. Only 15% of the patients were completely accepting their treatment having high necessity and low concerns, while 40% were ambivalent, having high necessity beliefs, but also high concerns, with 89% being adherent in this group. Overall, higher adherence was significantly correlated with higher necessity and with higher necessity-concern differential.

CONCLUSION

Patients beliefs have an impact on adherence, thus patients' concerns and necessities should be addressed in order to improve adherence and treatment outcome.

PRACTICE IMPLICATIONS

Higher necessity positively influenced adherence to treatment, suggesting the fact that healthcare professionals could improve patients' adherence by outlining and educating the patients on the necessity of the treatment, while also managing patients' concerns.

Clinical audit of adherence to hypertension treatment guideline and control rates in hospitals of different sizes in Thailand

A clinical audit of hospitals in Thailand was conducted to assess compliance with the national hypertension treatment guidelines and determine hypertension control rates across facilities of different sizes. Stratified random sampling was used to select sixteen hospitals of different sizes from four provinces. These included community (<90 beds), large (90–120 beds), and provincial (>120 beds) hospitals. Among new cases, the audit determined whether (i) the recommended baseline laboratory assessment was completed, (ii) the initial choice of medication was appropriate based on the patient's cardiovascular risk, and (iii) patients received medication adjustments when indicated. The hypertension control rates at six months and at the last visit were recorded. Among the 1406 patients, about 75% had their baseline glucose and kidney function assessed. Nearly 30% (n = 425/1406) of patients were indicated for dual therapy but only 43% of them (n = 182/425) received this. During treatment, 28% (198/1406) required adjustments in medication but this was not done. The control of hypertension at six months after treatment initiation was 53% varying between 51% in community and 56% in large hospitals (p < .01). The hypertension control rate at last visit was 64% but varied between 59% in community hospitals and 71% in large hospitals (p < .01). Failure to adjust medication when required was associated with 30% decrease in the odds of hypertension control (OR 0.69, 95% CI 0. 50 to 0.90). Failure to comply with the treatment guidelines regarding adjustment of medication and lost to follow‐up are possible target areas to improve hypertension control in Thailand.

Adherence to antihypertensive therapy and its determinants among patients attending primary care hospitals of Kashmir, India

Background:

Adherence to antihypertensive therapy is an important factor in determining the clinical course of hypertension. This study was planned to estimate adherence to antihypertensive therapy and its determinants among OPD patients attending two primary care hospitals in Kashmir valley.

Methods:

This study employed a cross-sectional study design. All subjects who reported to OPD between October and December 2020 and had been prescribed antihypertensive medications for at least 1 year were included. Sociodemographic information was collected on a pretested schedule and adherence to medications was assessed by using the-14 item Hill-Bone HBP Compliance to High Blood Pressure Therapy Scale (HB-HBP). Mann–Whitney test and Spearman’s rank correlation coefficient were used.

Results:

A total of 406 subjects were included in the final analysis with a mean age of 58 years for women and 56 years for men. The sample comprised 54% women. More than 60% of subjects were currently married, urban area residents, and belonged to middle strata of social class. The mean score obtained in the HB-MAS (maximum score 56) was 19.26 (SD ± 4.3). Subjects aged 60 years and above, those belonging to lower socioeconomic class, and subjects prescribed three or more drugs with more than once-daily dosing regimen had higher odds of having poor adherence.

Conclusion:

There is suboptimal adherence among OPD patients at primary care level. There is a need for enhanced counselling regarding medication adherence particularly for elderly, poor, illiterate persons and those prescribed multiple medicines with more than once-daily dosing.

Assessment of Medication Adherence and Related Factors in Hypertensive Patients: The Role of Beliefs About Medicines

Low medication adherence is one of the leading causes that affect the achievement of target levels for hypertension. Identifying modifiable factors associated with low adherence is crucial. This study aims to assess medication adherence and the role of beliefs about medicines on medication adherence among hypertensive patients.This cross-sectional study was conducted with 200 hypertension patients.Data were collected using the Morisky-Green-Levine Medication Adherence Scale, and the Beliefs about Medicines Questionnaire [BMQ-Turkish Translation (BMQ-T)]. It was found that the BMQ-T subscales of Specific Concern (β = 0.358, p = .027) and General Overuse (β = 0.552, p = .011) had an independent predictor effect on medication adherence scores. In this study, the patients who thought that drugs were overused and had concerns about this were seen to be less adherent with the medication. With regard to patients who use antihypertensive drugs but have uncontrolled blood pressure, their beliefs about drugs should not be ignored when evaluating adherence with drug therapy.

Patterns and Factors Associated with Self-Medication among the Pediatric Population in Romania

Background and objectives: Self-medication is a global phenomenon in both developed and emerging countries. At present, data regarding the practice, patterns, and factors associated with self-medication in Romanian patient groups of various ages and health are relatively scarce. A pilot study that uses a questionnaire was conducted to observe the attitudes as well as the behaviors of a group of Romanian parents related to self-medication, specifically their beliefs and perceived risks of the administration of medicine to their children without medical advice, frequency of self-medications, symptoms, and types of medications most commonly used without medical advice. Materials and Methods: The questionnaire was sent via e-mail or WhatsApp link on a mobile phone using the existing data at the general practitioner's office together with the protection of data form and the informed consent form; some participants completed the questionnaire when they came for a regular visit at the general practitioner's office. Of 246 applied questionnaires, we had a rate of responses of 98%. Results: We found a high percentage (70%) of parents who self-medicate their children. The data reveals a significant relation between parents' beliefs on self-medication and their tendency to administrate drugs to their children without medical advice. A significant relation was also found between the likelihood of parental self-medication for their children and the number of illnesses experienced by their children over the six-month period prior to the survey. Even when parents have a correct understanding of self-medication risks, these are not aligned with actual behavior; therefore, parents continue to administer drugs to their children without medical advice. Conclusions: Our study helps to describe the patterns of parents' decisions about self-medicating their children and to identify parents who are more predisposed to administering self-medication to their children.

Determinants of medication adherence among hypertensive patients using the Pender's health promotion model

BACKGROUND

Poor adherence in treatment and medication is a global issue in curing the chronic diseases such as hypertension. The present study was conducted to identify the factors related with medication adherence among hypertensive patients referred to the health centers of Borujerd based on the Pender's Health Promotion Model (HPM).

MATERIALS AND METHODS

This cross-sectional study was conducted on 463 patients who were referred to the comprehensive health centers of Borujerd city by cluster sampling method in 2019. The data were collected using a questionnaire including demographic variables and Pender's HPM constructs. Data were analyzed by SPSS 18 software using Pearson correlation coefficient and linear regression.

RESULTS

The mean and standard deviation of the participants' age was 63.29 ± 11.2 years. The results showed that hypertensive patients had a relatively desirable level of medication adherence behavior. Perceived barriers (β = -0.169), perceived self-efficacy (β = 0.196), activity related affect (β = 0.232), and following medication regimen (β = 0.225) were the best predictors of performing the medication adherence behavior. In total, different structures of the HPM explained 42.2% of the variation of medication adherence behavior changes.

CONCLUSIONS

According to the findings, the design of educational programs using HPM is recommended to increase the medication adherence among hypertensive patients.

Adherence to antihypertensive fixed-dose combination among Egyptian patients presenting with essential hypertension

Background

Many patients with hypertension require more than one drug to achieve blood pressure control. They are prescribed with fixed-dose combination (FDC) antihypertensive therapy rather than monotherapies. Although it is commonly admitted that the use of FDC may improve compliance to treatment, adherence rates in patients receiving FDCs have not been documented. Therefore, the aim of this study was to assess the adherence to treatment in patients receiving FDCs of antihypertensive medications in a real-world setting in Egypt.

Results

We conducted a multi-center cross-sectional study over a period of 1 year from Jan 2017 to Jan 2018. We included patients above 21 years old with essential hypertension who were already prescribed with an FDC of antihypertensive treatment for at least 3-month duration. We assessed the adherence to treatment by patient self-assessment using the Morisky 8-Item Medication Adherence Scale (MMAS 8).

This study enrolled 2000 hypertensive Egyptian patients. The mean age of enrolled patients was 55.8 ± 10.9 years. Male to female ratio was 1.08. The mean MMAS score was 6.5 ± 1.9. Our analysis showed that 825 (41.3%) patients reached high adherence score, 523 (26.2%) medium adherence, and 652 (32.6%) low adherence.

Furthermore, Male patients showed higher adherence rate than females (56.4% versus 43.6%, p < 0.001). Out of 746 patients with controlled blood pressure (< 140/90), 387 (51.9%) patients were highly adherent to treatment. Higher level of education was significantly associated with high adherence rate; 559 (67.8%) patients were university graduates, 232 (28.1%) had primary/secondary school education, and 34 (4.1%) were illiterate (p < 0.001).

Moreover, once daily (99.2%) fixed-dose combination was associated with higher adherence rate than twice regimen daily (0.8%), p = 0.03. Multivariate logistic regression analysis showed that patients with high level of education, employed patients, and patients with controlled blood pressure have high adherence rate to medication.

Conclusions

Higher adherence to medication is associated with high level of education and employment, and it can lead to better blood pressure control. Thus, patient education programs may increase patients’ adherence to their medication.

Using Goal-Directed Design to Create a Mobile Health App to Improve Patient Compliance With Hypertension Self-Management: Development and Deployment

Background

Hypertension is a lifestyle-induced chronic disease that threatens the lives of patients. Control of hypertension requires patients to follow self-management regimes; unfortunately, however, patient compliance with hypertension self-management is low, especially in developing countries. Improvement of patient compliance is premised on meeting patient needs. Mobile health apps are becoming increasingly popular for self-management of chronic diseases. However, few mobile apps have been designed to meet patient needs for hypertension self-management.

Objective

The goal of this study was to develop a mobile health app to improve patient compliance with hypertension self-management and evaluate the effectiveness of the app in terms of patient compliance.

Methods

The goal-directed design method was applied to guide study design. We divided the study into 4 stages. Stages 1 to 3 comprised the development process. To improve the applicability of the goal-directed design method to chronic disease management, we extracted elements of user models concerned with patient compliance and defined a concrete process for user modeling. In stage 1, personas of hypertensive patients were built using qualitative and quantitative methods. Clustering methods based on questionnaire responses were used to group patients. Qualitative interviews were conducted to identify the needs of different groups. In stage 2, several functional modules were designed to meet the needs of different groups based on the results from stage 1. In stage 3, prototypes of functional modules were designed and implemented as a real app. Stage 4 was the deployment process, in which we conducted a pilot study to investigate patient compliance after using the app. Patient compliance was calculated through the frequency with which they took blood pressure measurements. In addition, qualitative interviews were conducted to learn the underlying reasons for the compliance results.

Results

In stage 1, patients were divided into 3 groups based on 82 valid questionnaire responses. Eighteen patients from the different groups (7, 5, and 6 patients) were interviewed, and the needs of the groups were summarized as follows: improve self-management ability, enhance self-management motivation, and receive self-management support. In stages 2 and 3, 6 functional modules were designed and implemented based on specified needs, and the usability of the app was improved through usability tests. In stage 4, 143 patients were recruited to use different versions of the app for 2 months. Results show that patient compliance improved as functional modules were added (P<.001) and was maintained at a high level (rate of 0.73). Interview results from 32 patients show that the design of the app met different needs; thus, patients were more compliant with it.

Conclusions

This study developed a mobile health app for hypertension self-management using the goal-directed design method. The app proved to be effective for improving patient compliance with hypertension self-management.

Does the Polypill Improve Patient Adherence Compared to Its Individual Formulations? A Systematic Review

Many patients, especially those with a high pill burden and multiple chronic illnesses, are less adherent to medication. In medication treatments utilizing polypills, this problem might be diminished since multiple drugs are fused into one formulation and, therefore, the therapy regimen is simplified. This systematic review summarized evidence to assess the effect of polypills on medication adherence. The following databases were searched for articles published between 1 January 2000, and 14 May 2019: PubMed, Web of Science, Cochrane Library, and Scopus. Medication adherence was the only outcome assessed, regardless of the method of measuring it. Sixty-seven original peer-reviewed articles were selected. Adherence to polypill regimens was significantly higher in 56 articles (84%) compared to multiple pill regimens. This finding was also supported by the results of 13 out of 17 selected previously published systematic reviews and meta-analyses dealing with this topic. Adherence can be improved through the formulation of polypills, which is probably why the interest in researching them is growing. There are many polypills on the market, but the adherence studies so far focused mainly on a small range of medical conditions.

Analysis of Adherence to Antihypertensive Drugs in Chinese Patients with Hypertension: A Retrospective Analysis Using the China Health Insurance Association Database

OBJECTIVE

To analyze the adherence to antihypertensive drugs in Chinese patients with hypertension and the factors associated with the drug adherence.

METHODS

The data for this analysis were obtained from the 2014 China Health Insurance Association (CHIRA) database. The study included 64,576 patients aged ≥18 years who were prescribed one of the seven antihypertensive drugs included in the study in their first prescription in 2014 and were observed for ≥180 days. The medicine possession ratio (MPR) was calculated and taken as the measure of treatment adherence. MPR values <0.3, 0.3 to <0.5, 0.5 to <0.8, and ≥0.8 were considered treatment adherence very low, low, intermediate, and high, respectively. Descriptive statistics were used to present baseline data and treatment adherence rate. Multiple regression models were used to determine independent factors which can affect the treatment adherence rate. P-value <0.05 was considered significant.

RESULTS

Among the study antihypertensive drugs, amlodipine (33.98%), metoprolol (25.04%), and nifedipine (17.15%) were the frequently prescribed drugs. Nifedipine controlled release tablet had the highest MPR (0.61), followed by valsartan (0.53), valsartan/amlodipine fixed-dose combination (0.50), indapamide (0.40), and amlodipine (0.39), whereas benazepril (0.27) and metoprolol (0.19) had the lowest MPR. Higher reimbursement ratio, regular tertiary hospitals visits, lower age, and lower daily medical cost positively affected treatment adherence, whereas longer duration of illness and higher daily average cost affected treatment adherence negatively.

CONCLUSION

Our study assessed that prescribing more cost-effective, long-acting antihypertensive drugs, and raising the reimbursement ratio were associated with a better treatment adherence in Chinese patients with hypertension.

Perceived Illness and Treatment Adherence to Hypertension Among Patients Attending a Tertiary Hospital in Kathmandu, Nepal

INTRODUCTION

Hypertension (HTN) is a silent killer, accountable for life-threatening complications. An individual's illness perception may affect adherence to treatment which is crucial to prevent complications of HTN. The objective of this study was to identify illness perception and treatment adherence among patients with HTN in a tertiary hospital in Kathmandu, Nepal.

METHODS

Descriptive correlational study was conducted in the out-patient department of Manmohan Cardiothoracic Vascular and Transplant Center, Kathmandu Nepal. Non-probability purposive sampling was used. A face-to-face interview was conducted from September to December 2018, using a structured questionnaire that included socio-demographic variables, illness perception questionnaire (revised) and Hill bone compliance to high blood pressure therapy scale. Data analysis was done by using descriptive and inferential statistics (chi-square test, Spearman rank correlation).

RESULTS

Among 204 participants, 51% were male, 77% were literate, mean ± S.D. age was 60±12. About 72% experienced headache and 88% said that headache is related to HTN. Behavioural factors and psychological factors were regarded as the leading cause of HTN. Almost 63% participants believed HTN as highly threatening illness. Higher scores in timeline (acute/chronic), personal control, and treatment control revealed that patients believed HTN as a chronic disease with a higher rate of personal and treatment control. Regarding treatment adherence, the mean score was 16.58 (SD = 2.08), and only 14.7% had perfect adherence. Participants were more adherent to medication and appointment keeping rather than reduce salt intake. Duration of HTN diagnosis (p=0.027) and duration under HTN medication (p= 0.021) were found to be significantly associated with treatment adherence. There was a significant positive correlation between illness perception and treatment adherence (ρ = 0.282, p<0.01).

CONCLUSION

Illness perception and treatment adherence are correlated. Hence, it is beneficial to improve illness perception to achieve perfect treatment adherence. Reinforcement is essential to maintain adherence to both medications and behaviour therapy.

Assessment of suicidal behavior in dermatology (Review)

Many diseases that affect physical health can also affect mental health. Many of these diseases are studied in terms of quality of life, depression and suicidal behavior. Dermatological disorders, although having a strong impact on the individual's life, are less studied with regard to suicidal behavior. There is a need to approach several dermatological diseases from the perspective of suicidal behavior in order to intervene early with specific treatment or to prevent suicide. Psoriasis, acne, melanoma, atopic dermatitis and urticaria are scarcely studied from the point of view of suicidal behavior. In addition to these diseases, there are others that require attention in terms of suicidal behavior, such as vitiligo or oculocutaneous albinism, most probably due to a small number of people suffering from these diseases, research is almost non-existent in these cases. We want to draw attention to the importance of early detection of suicidal behavior in dermatological practice and to highlight the need for several studies on this subject.
