Dela Cruz FA, Yu CHA, Lao BT. Illness perceptions and blood pressure control among hypertensive Filipino Americans: A cross-sectional study. J Am Assoc Nurse Pract 2024:01741002-990000000-00228. [PMID: 38874461 DOI: 10.1097/jxx.0000000000001032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 04/26/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND Among Asian Americans, Filipino Americans (FAs)-who constitute the fourth largest US immigrant group and who fill in health care workforce shortages-experience high prevalence but low control rates of high blood pressure (HBP). Research reveals that patients' illness perceptions, their common-sense model (CSM) of the illness, influence treatment behaviors, and management outcomes. However, scarce information exists about FAs' perceptions about HBP. PURPOSE To address this gap, we conducted a cross-sectional study to (a) identify the illness perceptions of hypertensive FAs, (b) classify these perceptions into clusters, and (c) determine the association between illness perceptions and BP control. METHODOLOGY The responses of 248 FAs with HBP to the Brief Illness Perception Questionnaire were analyzed using JMP Pro version 17 to discover their CSMs or illness perceptions. We used iterative K means cluster analysis to classify variations in CSMs and analysis of means chart to determine the association of illness perceptions and BP control. RESULTS Hypertensive FAs expressed threatening (negative) views of HBP through their emotional perceptions of the illness and its chronic time line, whereas their positive views centered on their cognitive beliefs about understanding HBP and its controllability. Based on the biomedical model of HBP, the overall illness perceptions or CSMs encompassed three clusters. Generally, threatening illness perceptions were associated with stage 2 HBP. CONCLUSIONS/IMPLICATIONS The findings underscore the need for nurse practitioners to elicit, listen, discern, and understand the illness perceptions or CSMs of hypertensive FAs to improve BP treatment and control with scientifically and culturally tailored interventions.

A cross-sectional study on adherence to treatment and life-style modifications in hypertensive patients attending the urban health centre of a teaching hospital in Hyderabad. J Family Med Prim Care 2023; 12:3129-3134. [PMID: 38361900 PMCID: PMC10866269 DOI: 10.4103/jfmpc.jfmpc_588_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 06/19/2023] [Accepted: 06/20/2023] [Indexed: 02/17/2024] Open
Abstract
Introduction The burden of hypertension is expected to double by 2025 and adherence to treatment has a key role in disease outcome. The World Health Organization defines adherence as the extent to which a person's behaviour of taking medication, following a diet and/or exceeding life-style changes, corresponds with the agreed recommendations of health care providers. The study tries to assess the level of adherence to medication and life-style modifications in hypertensive patients. Materials and Methods It is a cross-sectional study among patients attending urban health centres of a teaching hospital. The study population included all hypertensive patients above 30 years. Based on the prevalence of non-adherence to hypertensive medication, 70% of the sample size is calculated as 182. A Morisky medication adherence scale is used to find adherence to treatment. Life-style modification was also assessed. Scoring was done based on their adherence to treatment and life-style modifications and quantified. Results The mean age of the study population was 55 years (38-80 years). In total, 58.33% were illiterate and 21% were retired from work. Around 87.5% had to spend money on medication. Mean weight, height, hip and waist circumference was 66 kg, 157 cm, 108 cm and 100 cm, respectively. Mean BMI was 26.6. Prevalence of good adherence to medication was 129 (70.83%) and that of good life-style modifications was 127 (70.17%). Conclusion The adherence to medication and life-style modification was satisfactory. Family physicians have a key role in Non communicable diseases (NCD) management and should focus on ongoing education programmes for treatment adherence and life-style modifications at a community level, and grass-root level workers should conduct regular follow-up activities.

Abstract
BACKGROUND Lack of adherence to treatment in patients with arterial hypertension leads to poor blood pressure control, increased morbidity and mortality, and increased costs to health and social care. Regular assessment of treatment adherence as well as factors influencing it is important to improve patient adherence and consequently increase treatment efficacy. Personal beliefs, particularly illness representations, are significant factors that influence adherence. OBJECTIVE The aim of this study was to assess the associations between adherence to treatment, illness perception, and selected sociodemographic and clinical characteristics in patients with arterial hypertension. METHODS In this cross-sectional observational study, 235 patients with arterial hypertension completed the Hill-Bone Compliance to High Blood Pressure Therapy Scale and the Brief Illness Perception Questionnaire. Associations between variables were assessed by Spearman ρ and multiple linear regression analysis. RESULTS Younger age, male gender, overall number of drugs used, and poorer beliefs related to the timeline, treatment control, and understanding were associated with higher levels of nonadherence. The final regression model significantly ( P ≤ .05) explained 19.4% of the variance in diet adherence, 5.0% in appointment keeping, and 17.8% in medication adherence. CONCLUSION Comprehensive care aimed at regular evaluation of illness perceptions with an emphasis on increasing understanding of the disease and its treatment and reducing patient worries and negative emotions seems to be a relevant strategy for improving adherence to antihypertensive treatment in everyday clinical practice.

Abstract
Background Nepal is a low resource country with cardiovascular diseases being the number one cause of mortality. Despite hypertension being the single most important risk factor for cardiovascular diseases, non-adherence to anti-hypertensive medications has not been assessed systematically. So, this systematic review and meta-analysis aims to analyze the prevalence of non-adherence to anti-hypertensive medications in Nepal. Methodology This systematic review and meta-analysis was piloted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Electronic databases of Embase, PubMed, Scopus, Web of Science, Cochrane Library, Cinhal Plus, and Google Scholar were searched from inception till 1 February 2023. The random-effects model with 95% confidence interval (CI) was used to calculate the non-adherence rate. Results Altogether, 14 studies with a total of 3276 hypertensive patients were included in the meta-analysis. The pooled prevalence of non-adherence to anti-hypertensive medications was 49% (95% CI: 0.37-0.62, I2=98.41%, P<0.001). The non-adherence rate using Morisky Medication Adherence Scale (MMAS) was 55% (95% CI: 0.34-0.76, I2=99.14%, P<0.001), and using Hill-Bone Compliance Scale, the non-adherence rate was 45% (95% CI: 0.37-0.54, I2=84.36%, P<0.001). In subgroup analysis, the non-adherence was higher in rural areas 56% (95% CI: 0.51-0.61, I2=0.0%, P=0.46) compared to urban areas 42% (95% CI: 0.31-0.54, I2=96.90%, P<0.001). The trend of non-adherence was increasing after 2020. Additionally, forgetfulness, carelessness, cost of medications, number of comorbidities, and using an alternate form of medication were common factors associated with non-adherence. Conclusions This meta-analysis showed that half of the hypertensive population of Nepal are non-adherent to their anti-hypertensive medications, thereby posing a significant long-term cardiovascular consequence among Nepali population.

Abstract
Background and Aims Hypertension is the third leading cause of death in the world and is estimated to be increased by about 60% by 2025. Beliefs about hypertension can predict patient adherence to hypertension treatment. This study aims to investigate the perceptions of hypertension and adherence to hypertension treatment among patients in Khorramabad, Iran. Methods This is a descriptive/analytical study with a cross-sectional design. Participants were 265 patients with a history of hypertension referred to a hospital in Khorramabad, Lorestan Province in western Iran in 2020, who were selected using a convenience sampling method. A demographic form, the brief illness perception questionnaire-revised (BIPQ-R), and Morisky medication adherence scale (MMAS-8) were used for collecting data. The collected data were analyzed in SPSS v.22 software using descriptive statistics, Pearson's correlation test, independent t-test, one-way ANOVA, and regression analysis. Results The mean scores of BIPQ-R and MMAS-8 were 49.05 ± 15.45 (out of 80) and 3.69 ± 1.62 (out of 8), respectively. There was a significant relationship between the mean scores of MMAS-8 and BIPQ-R in total (p < 0.001). Perceptions of illness consequences (B = 4.59, p = 0.005), personal control (B = 0.190, p = 0.047), and symptoms (B = 1.77, p = 0.005) could significantly predict treatment adherence of patients. In illness perception, there were significant differences among patients with different places of residence (p = 0.032), educational levels (p = 0.001), and employment status (p = 0.010). In treatment adherence, there were significant differences among patients with different places of residence (p = 0.042) and educational levels (p = 0.045). Conclusion Treatment adherence of hypertensive patients in western Iran is at a low level, while their perception of hypertension is at a moderate level. Clinical physicians are recommended to pay attention to the perception of illness in these patients (especially unemployed and less educated patients living in rural areas) to improve their adherence to treatment and blood pressure control.

Abstract
ABSTRACT Despite separate evidence regarding illness perception (IP) and group medical visits (GMVs) for hypertension, research on both is limited. Here, we have assessed and compared the effectiveness of GMVs and usual care (UC) on IP and blood pressure (BP) in patients with hypertension. This was a two-group parallel randomized controlled study with 1:1 allocation. Patients with essential hypertension on antihypertensive medication and no cognitive impairments were screened for BP control status and eligibility. A web-based program randomly assigned them to the GMV and UC groups. Group medical visits were held once a month for 3 months. Primary and secondary outcome measures included improvements in IP and BP control. Among 152 participants, 40 and 43 were assigned to the GMV and UC groups, respectively. The control group had a 9.3% dropout rate. The chronic timeline and illness coherence improved significantly in the intervention group ( p < .01). Systolic BP in the intervention group decreased significantly compared with that of the control group (Δ: -18.8 ± 18.4 mm Hg vs. Δ: -10.6 ± 12.5 mm Hg, p = .025). The participation in GMVs had a significant association with the odds of an increase in BP regulation (OR 3.8, 95% confidence interval 1.4-10.3, p = .007). Therefore, GMVs may be feasible for BP control in hypertensive patients with similar characteristics.

Abstract
Background Knowledgeable people are more likely to follow their treatment plan and reduce hypertension morbidity and mortality. This study aimed to construct the validity and reliability of the Arabic version of the Hypertension Knowledge-Level Scale (HK-LS) among Saudis. Methods This cross-sectional questionnaire research targets hypertensives and non-hypertensives. Cronbach's alpha and Spearman's correlation matrix analysis measured the questionnaire's construct validity. Wilcoxon rank sum tests examined HK-LS tools' discriminant validity. A p<0.05 was considered significant. Results A total of 1424 responses were received. However, the 1419 individuals were evaluated after applying exclusion criteria. About 60% of the participants were female, with the most common age groups being 18-29 years (38.5%) and 40-49 years (24.0%). A personal history of hypertension was reported by 26.1%, and a family history of hypertension by 73.3% of the subjects. Cronbach's alpha for the whole HK-LS was 0.883, suggesting that the tool was reliable. All the items of the HK-LS questionnaire were significantly correlated with each other, except for a non-significant correlation between statements two and seven (r=0.05, p=0.091). The strongest correlations were apparent between items 19 and 20 (r=0.70, p<0.0001), items one and two (r=0.64, p<0.0001), and items 18 and 19 (r=0.56, p<0.0001). However, the weakest associations were reported among items two and six (r=0.06, p<0.05), items two and nine (r=0.07, p<0.05), and items one and 19 (r=0.07, p<0.05). The discriminant validity showed that a personal history of hypertension was associated with significantly higher scores of two HK-LS subscales, including definitions and complications. In addition, the overall knowledge score was significantly higher among participants with a positive history of hypertension among family and/or friends. Conclusions The Arabic version of the HK-LS was found to be a reliable and valid tool for measuring knowledge about hypertension among the Saudi population. This reliable instrument can assist medical professionals in establishing education programs.

Abstract
Background Hypertension is one of the leading causes of morbidity and mortality in Saudi Arabia affecting 31.4% of the population. The Illness Perception Questionnaire-Revised (IPQ-R) is a validated and reliable tool for assessing the perception of hypertension among patients. This cross-sectional study aimed to translate the Revised Illness Perception Questionnaire (IPQ-R) into Arabic and validate it among Arabic patients with hypertension from the outpatient departments of the Prince Sattam University Hospital and King Khalid Hospital (KKH) in Al-Kharj City in the Kingdom of Saudi Arabia. Methods A bilingual panel of doctors and medical translators was assembled to translate the IPQ-R into Arabic. The questionnaire was administered to 100 adult Arabic speaking patients with clinically diagnosed primary hypertension. Patients with secondary hypertension or complications of hypertension were excluded from the study. Results Fifty-seven patients (57%) were male and sixty-five (65%) were older than 40 years. Headache was the most common symptom of hypertension reported by 65% of the participants. The internal consistency of the questionnaire excluding the domain of 'Disease Identity' was 0.76 indicating satisfactory consistency. There were weak to moderate positive linear correlations (r = 0.003-0.561) between the domains of IPQ-R suggesting a reasonable discriminant validity among the domains. Conclusion The Arabic version of the IPQ-R for hypertensive patients is a consistent, valid, and reliable tool to be used by researchers or clinicians for assessing knowledge, beliefs, and attitudes of Arabic speaking patients with hypertension living in Saudi Arabia.

Abstract
Introduction: Nonadherence to antihypertensive medications is recognized as a significant cause of treatment failure. Therefore, identifying its underlying factors, particularly from the patient’s perspective, is essential for developing tailored intervention strategies. The objective of this study was to evaluate the associations between different domains of illness perception and medication nonadherence among patients with hypertension in Indonesia. Patients and methods: A multicenter cross-sectional study was conducted among patients with hypertension aged 18 years old and older who were using antihypertensive medications in the last 3 months in the community health centers in the three cities in Indonesia. The different domains of illness perception (e.g., consequences, timeline, personal control, treatment control, identity, concerns, comprehension, and emotional response) and medication nonadherence were assessed using a validated Brief Illness Perceptions Questionnaire (BIPQ) and Medication Adherence Report Scale (MARS), respectively. A logistic regression analysis was conducted to evaluate the associations between the different domains of illness perception and medication nonadherence adjusting for confounders. The odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Results: A total of 440 participants were included, whom 41.8% reported nonadherence to antihypertensive medications. The majority of the participants were females (64.3%) and aged between 60 and 69 years old (39.5%). The treatment control (OR: 0.80, 95% confidence interval: 0.7–10.90), patient’s comprehension of hypertension (OR: 0.89, 95% CI: 0.820–0.97), and patient’s emotions (OR: 0.93, 95% CI: 0.88–0.99) were significantly associated with medication nonadherence. No significant associations were observed between the other domains of illness perception and medication nonadherence. Conclusion: Different dimensions of illness perception were associated with non-adherence to antihypertensive medications. Educational interventions should be developed based on patients’ perception of their illness.

Abstract
Background Nonadherence to antihypertensive medications is the leading cause of poor blood pressure control and thereby cardiovascular diseases and mortality worldwide. Methods and Results We investigated the global epidemiology, regional differences, and trend of antihypertensive medication nonadherence via a systematic review and meta‐analyses of data from 2010 to 2020. Multiple medical databases and clinicaltrials.gov were searched for articles. Observational studies reporting the proportion of patients with anti‐hypertensive medication nonadherence were included. The proportion of nonadherence, publication year, year of first recruitment, country, and health outcomes attributable to antihypertensive medication nonadherence were extracted. Two reviewers screened abstracts and full texts, classified countries according to levels of income and locations, and extracted data. The Joanna Briggs Institute prevalence critical appraisal tool was used to rate the included studies. Prevalence meta‐analyses were conducted using a fixed‐effects model, and trends in prevalence were analyzed using meta‐regression. The certainty of evidence concerning the effect of health consequences of nonadherence was rated according to Grading of Recommendations, Assessment, Development and Evaluations. A total of 161 studies were included. Subject to different detection methods, the global prevalence of anti‐hypertensive medication nonadherence was 27% to 40%. Nonadherence was more prevalent in low‐ to middle‐income countries than in high‐income countries, and in non‐Western countries than in Western countries. No significant trend in prevalence was detected between 2010 and 2020. Patients with antihypertensive medication nonadherence had suboptimal blood pressure control, complications from hypertension, all‐cause hospitalization, and all‐cause mortality. Conclusions While high prevalence of anti‐hypertensive medication nonadherence was detected worldwide, higher prevalence was detected in low‐ to middle‐income and non‐Western countries. Interventions are urgently required, especially in these regions. Current evidence is limited by high heterogeneity. Registration URL: www.crd.york.ac.uk/prospero/; Unique identifier: CRD42021259860.

Abstract
BACKGROUND AND OBJECTIVES Optimal blood pressure control is achieved by medication adherence. This will reduce the risk of associated morbidities and mortalities. The present study aimed to determine medication adherence and its associated factors among hypertensive patients attending different primary health centers (PHC) in Abha, Saudi Arabia (KSA). METHODS A cross-sectional study was conducted among ten different PHCs in Abha, KSA. Simple random sampling procedure was utilized to choose 400 participants. A structured anonymous questionnaire was used in the present study. Analysis of the data was done using the SPSS program, version 23. A logistic regression statistical test was applied to identify the independent associated factors of medication adherence. Furthermore, we have applied Spearman's test to find the correlation between overall B-IPQ score and medication adherence score. RESULTS A total of 400 hypertensive patients responded in the present survey. More than one-third of the participants (36.3%) were in the high adherence category group, while the remaining participants (63.7%) were either low or medium adherence category. The binary logistic regression analysis revealed that low and medium adherence category is significantly associated with age (adjusted odds ratio [AOR] = 0.96, 95% CI =0.93-0.99, p = 0.021), married participants (AOR = 0.42, 95% CI =0.33-0.58, p = 0.001), residing at village (AOR = 1.49, 95% CI =1.14-1.73, p = 0.038), and participants with monthly family income of 5000 to 7000 SAR (AOR = 3.06, 95% CI =1.62-5.79, p = 0.001). A negligible positive correlation was revealed between illness perception and medication adherence. CONCLUSION The present study revealed that hypertensive patients poorly adhere to their antihypertensive medications. This low adherence is significantly associated with the age, monthly income, people living in rural areas, and married participants. The present study results recommend sustained efforts to implement health education programs and awareness-raising interventions targeted at hypertensive patients.

Translation, Cultural Adaptation and Validation of the Hill Bone Compliance to High Blood Pressure Therapy Scale to Nepalese Language. Patient Prefer Adherence 2022; 16:957-970. [PMID: 35422613 PMCID: PMC9005151 DOI: 10.2147/ppa.s349760] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2021] [Accepted: 02/14/2022] [Indexed: 12/19/2022] Open
Abstract
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.

Patient Prefer Adherence 2021; 15:1873-1885. [PMID: 34475753 PMCID: PMC8407778 DOI: 10.2147/ppa.s320866] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 07/29/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The General Medication Adherence Scale (GMAS) evaluates intentional and unintentional behaviour of patients, disease and medication burden and cost-related burden associated with non-adherence. GMAS was developed and validated among Urdu-speaking patients with chronic diseases. However, validated tool in Nepalese language to measure medication adherence among chronic illness patients currently does not exist. AIM To translate, culturally adapt, and validate the English version of GMAS into the Nepalese language to measure medication adherence among chronic illness patients. METHODS The study was conducted among patients with chronic diseases in both hospital and community pharmacies of Nepal. The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Good Practice Guideline for linguistic translation and cultural adaptation was used to translate and culturally adapt the English version of GMAS into the Nepalese version. The translated version was validated amongst patients with chronic diseases in Nepal. Exploratory factor analysis was carried out using principal component analysis with varimax rotation. Test-retest reliability and internal consistency were analysed. RESULTS A total of 220 (53.6% females, and 51.4% of 51 to 70 aged patients) patients with chronic diseases participated in the study. The majority of patients took two medications (27.3%) from six months to five and half years (68.2%). Kaiser Meyer Olkin was found to be 0.83. A principal axis factor analysis was conducted on the 3 items of GMAS without and with orthogonal rotation (varimax). The scree plot showed an inflexion on the third item that meant three components were present. The overall Cronbach's alpha value of the full-phase study was 0.82. CONCLUSION The General Medication Adherence Scale was successfully translated into the Nepalese language, culturally adapted, and validated amongst chronic diseases patients of Nepal. Therefore, the GMAS-Nepalese version can be used to evaluate medication adherence among Nepalese-speaking patients with chronic disease.
