Assessing Barriers to and Level of Adherence to Hypertension Therapy among Palestinians Living in the Gaza Strip: A Chance for Policy Innovation

Prevalence of hypertension in community members in a low-income community in Windhoek, Namibia

BACKGROUND

 Hypertension remains a significant risk factor for the development of several non-communicable diseases such as stroke, myocardial infarction and renal failure. In many African countries, undiagnosed and unmanaged hypertension within the population remains a challenge. Proactive screening and health education therefore become important interventions.

AIM

 This study aimed to investigate the prevalence of hypertension among community members in a low-income, peri-urban community.

SETTING

 The study was conducted in Otjomuise township, Windhoek, Namibia.

METHODS

 A quantitative, cross-sectional design with a survey method was followed. A pre-validated health screening instrument was used to record the presence of hypertension in a sample of 358 community members who presented for screening over 2 days. A purposive sampling method was employed. Systolic and diastolic blood pressure reading were recorded, analysed and categorised using the American Heart Association classification scale. Blood pressures were classified as being either normal, elevated, hypertension stage 1 or hypertension stage 2. The data were analysed by a statistician using SPSS version 27 statistical software program and presented in tables.

RESULTS

 A total of 210/358 (59%) of participants were found to have blood pressures within normal limits. Moreover, 57/358 (16%) had elevated blood pressures, 52/358 (14%) were in hypertension stage 1 and 39/358 (11%) were in hypertension stage 2.

CONCLUSION

 The 41% prevalence of abnormally elevated blood pressures found in our study is in line with the findings of other studies and confirms that hypertension in the Namibian population remains an ongoing public health concern. Larger scale and more regular screening exercises with appropriate referral are recommended.Contribution: Our study give insight on the prevalence of hypertension in a community in Namibia.

Evaluation of medication adherence and its relevant factors among hypertensive patients: A cross-sectional study in Shahrekord health-care system

BACKGROUND

Medication adherence means compliance with patient adherence to medication orders, including timely and correct consumption of medication prescribed by a physician. The present study aimed to determine the extent of adherence to hypertension drug medication in patients covered by comprehensive health service centers of Shahrekord, Iran.

MATERIALS AND METHODS

A cross-sectional study examined 401 hypertensive patients registered in the Integrated Health Record System (SIB). SIB is a Persian term related to Health Record System. To collect data, Morisky Medication Adherence Scale was used. The questionnaire was completed by the patients and analyzed using SPSS (SPSS Inc., Chicago, Illinois, USA, version 26), Chi-square test, independent t-test, and analysis of variance.

RESULTS

The results indicated that adherence to antihypertensive medication was low in 5.7% of patients, while 63.3% of patients had sufficient compliance. Forgetting to take medications (52.9%) was the most common reason for nonadherence to medication in hypertensive patients.

CONCLUSION

Given that forgetting to take medications was the main reason for nonadherence to medication in hypertensive patients, designing and implementing necessary trainings by comprehensive health centers to realize the importance of daily use of medication by hypertensive patients and their families are recommended.

A Cross-Sectional Study on Hypertension Medication Adherence in a High-Burden Region in Namibia: Exploring Hypertension Interventions and Validation of the Namibia Hill-Bone Compliance Scale

In Namibia, the prevalence of hypertension among women and men aged 35−64 years is high, ranging from 44% to 57%. In this study, we aimed to determine adherence and predictors to antihypertensive therapy in Khomas region, Namibia. A cross-sectional study was performed to consecutively sample 400 patients from urban and peri-urban settings in Namibia. Results were validated using the Hill-Bone Compliance to High Blood Pressure Therapy Scale. Crude associations between predictors of adherence and compliance were tested using the Pearson chi-square test. A multivariable logistic regression analysis was then performed on adherence variables found to be significant to adjust for confounders, and the results are presented as adjusted odds ratios (aOR) with 95% confidence intervals. A total of 400 patients participated in this study. The participants’ mean age and standard deviation were Mean ± SD = 48.9 ± 12.5. In this study, 351 (87.7%) patients were estimated to have good adherence. Education, employment, and the presence of other chronic diseases were associated with adherence. Following multivariate adjustment, the following factors were significantly associated and are therefore predictors of adherence (95%CI, p < 0.005): receiving enough medication at last check-up until next one (OR = 5.44, CI 1.76−16.85), lack of encouragement from family and friends (OR = 0.11 (0.03−0.42)), and attendance of follow-ups on schedule (OR = 8.49, CI = 3.82−18.85). The success of hypertension therapy is dependent on the healthcare systems and healthcare professionals in supplying enough medication, support of friends/family, and maintaining scheduled follow-ups. A combination of interventions using low-cost mobile technology led by healthcare professionals could be endorsed. To fully practice universal access to medication, public and private hospitals in Namibia should collaborate.

Factors Associated with Suboptimal Adherence to Hypertensive Medications Among Syrian Refugees - Cross-Sectional Study at the Zaatari Camp, Jordan

OBJECTIVE

This study aimed to assess the level of medication adherence and associated factors among Syrian refugees with hypertension in Jordan.

METHODS

This cross-sectional study included 180 randomly selected Syrian refugees diagnosed with hypertension residing in Zaatari camp, Jordan. The Adherence to Refills and Medications Scale (ARMS) was used to assess adherence to antihypertensive medications. Additional data were collected on sociodemographics, therapy-related factors, patients' behaviors and knowledge of hypertension disease and therapy, and health system-related factors. Multivariate linear regression was used to assess the association between adherence scores and other variables.

RESULTS

The mean (SD) of ARMS scores was 15.7 (2.9). Based on ARMS scores, 22.8% of patients were adherents and 77.2% were non-adherents. Multivariate analysis showed that newly initiated therapy (≤2 years) and illiteracy were both strong predictors of lower adherence with p < 0.001 and p = 0.012, respectively. Other variables that were significantly associated with lower adherence included discontinuation of antihypertensive medications due to side effects (p = 0.032), reporting irregular availability of free antihypertensive medications dispensed by non-governmental organizations (NGOs) (p = 0.024), and dissatisfaction with health services (p = 0.022).

CONCLUSION

Suboptimal adherence to antihypertensive medications remains a substantial unmet need among Syrian refugees with hypertension. As illiteracy appears to have a negative impact on adherence levels, educational interventions that promote medication adherence and favorable health behaviors through auditory and visual aids are needed to better reach and engage people with limited literacy skills. Strengthening the pharmaceutical supply chain at various levels is strongly recommended to respond quickly to changes in demand and prevent an indirect negative impact on adherence levels.

Evaluation of Frailty Syndrome and Adherence to Recommendations in Elderly Patients with Hypertension

Frailty syndrome (FS) often coexists with many diseases of the elderly, including arterial hypertension, and may affect the disease course and adherence to therapeutic recommendations. This study aimed to evaluate the relationship between frailty and adherence to therapeutic recommendations in elderly hypertensive patients. The study included 259 patients hospitalized between January 2019 and November 2020 due to exacerbation of hypertension symptoms. Medical records were used to obtain basic sociodemographic and clinical data. The study was based on the Tilburg Frailty Indicator (TFI) and the Hill-Bone Scale (HBCS). The obtained data were analyzed within a cross-sectional design. The mean frailty score indicated by the TFI questionnaire was 7.09 ± 3.73. The most prominent FS component was associated with the physical domain (4.24 ± 2.54). The mean overall adherence measured with the HBCS was 20.51 ± 3.72. The linear regression model testing the Hill-Bone "reduced sodium intake" score against the TFI domains showed no relationships between the variables. Another regression model for the Hill-Bone "appointment-keeping" subscale indicated significant predictors for physical and social TFI domains (p = 0.002 and p < 0.0001, respectively). For the Hill-Bone "taking antihypertensive drugs" variable, the regression model found significant relationships with all TFI domains: physical (p < 0.0001), psychological (p = 0.003) and social (p < 0.0001). Our study suggests that frailty in patients with arterial hypertension can negatively impact their adherence to therapeutic recommendations.
