Poor drug adherence and lack of awareness of hypertension among hypertensive stroke patients in Kampala, Uganda: a cross sectional study

[Evaluation of the management of hypertension among stroke patients in a neurology department of Côte d'Ivoire]

Introduction

Reducing blood pressure after stroke is important to prevent recurrent stroke, but we have no data about the control of blood pressure in our context. The purpose of this study was to assess management of hypertension among post-stroke patients in a neurology department.

Method

It was a retrospective study involving hypertensive stroke patients. They were followed up at 1, 3, 6 and 12 months after discharge.

Results

141 patients fulfilled the inclusion criteria. The mean age was 61 years. Almost all patients (94.3%) received a dual antihypertensive therapy combining mainly an ACE inhibitor and a diuretic (70.2%). During follow-up, only 76 patients were assessed at M1, 50 at M3, 44 at M6 and 42 at M12. The average monthly cost of antihypertensive treatment was 13,771 CFA francs (21 euros). Non-adherence to antihypertensive medication were mostly noted in widows, patients without occupation, those with low education and no health insurance. At one year, blood pressure was controlled in 80% of the 42 patients still present. Non-control of blood pressure was related to poor therapeutic compliance (p<0.05).

Conclusion

This study highlights follow-up issues in hypertensive post-stroke patients with a high number of lost to follow-up. Blood pressure was controlled in patients who were regularly followed and adherent to antihypertensive treatment.

Mediation role of perceived social support between recurrence risk perception and health behaviour among patients with stroke in China: a cross-sectional study

OBJECTIVES

To examine whether patients who had a stroke with high recurrence risk perception would have healthier behaviour and to explore whether perceived social support would function as a mediator.

DESIGN

A cross-sectional study.

SETTING

The study was conducted in a public tertiary hospital in China.

PARTICIPANTS

A total of 254 patients with stroke were invited to participate, and 250 patients with stroke completed questionnaires validly.

PRIMARY AND SECONDARY OUTCOME MEASURES

Questionnaires were administered offline to collect data, consisting of four parts: general demographics and scales related to recurrence risk perception, perceived social support, and health behaviour. A path analysis and correlation analysis were used to analyse the data.

RESULTS

Out of 250 patients with stroke, 78.4% had moderately low health behaviour. The majority (70.8%) of these patients were elderly. High recurrence risk perception and high perceived social support were significantly associated with better health behaviour (all p<0.001). Perceived social support mediated the relationship between recurrence risk perception and health behaviour after controlling for age, gender, education and monthly income in the regression model (95% CI 0.263 to 0.460) and the effect value was 0.360. It was also confirmed that perceived social support had the highest mediation effect with a proportion of mediation up to 59.31%.

CONCLUSIONS

Recurrence risk perception and perceived social support were influential factors in promoting health behaviour. Moreover, the impact of recurrence risk perception on health behaviour was partially mediated by perceived social support. Therefore, to enhance the sustainability of health behaviour, it is crucial to inform patients with stroke about the risk of recurrence. Patients with more perception of recurrence risk can improve their recovery confidence and thus perceive more social support.

Measurement Tools and Utility of Hair Analysis for Screening Adherence to Antihypertensive Medication

Poor adherence to the prescribed antihypertensive therapy is an understated public health problem and is one of the main causes of the high prevalence of uncontrolled hypertension in sub-Saharan Africa. Medication adherence is vital for the effectiveness of antihypertensive treatment and is key to ameliorating the clinical outcomes in hypertensive patients. However, it has often been ignored because the current methods used to assess medication adherence are not reliable, limiting their utilization in clinical practice. Therefore, the identification of the most accurate and clinically feasible method for measuring medication adherence is critical for tailoring effective strategies to improve medication adherence and consequently achieve blood pressure goals. This review not only explores various available methods for estimating medication adherence but also proposes therapeutic drug monitoring in hair for the measurement of medication adherence to the antihypertensive medication period.

Effects of blood pressure unawareness and poor adherence to antihypertensive drugs on outcomes of cerebrovascular accidents among patients with their first-ever stroke

AIMS

Our main target was to investigate the relationship of blood pressure (BP) unawareness and poor antihypertensive drug adherence with the clinical outcomes of the stroke including hospitalization time, degree of disability, and mortality rate.

METHODS AND RESULTS

In this cross-sectional study, we evaluated 530 eligible patients (male = 313; female = 217), aged 18 years and older who had a proven diagnosis of nontraumatic first-ever stroke and were referred to the Shahid Beheshti Hospital of Hamadan, Iran, during the period from March 2019 to September 2021. The prevalence of BP unawareness was 19.6%, and 31.8% of antihypertensive drug users (14.3% of all studied population) had poor drug adherence, in which, older age, male gender, marriage, rural residence, and smoking were associated with the lack of appropriate drug adherence. There was no significant difference between patients with diverse stroke types (ischemic or hemorrhagic) from the points of BP awareness and adherence to antihypertensive drugs; nevertheless, patients with a positive history of cardiac diseases had a significantly higher awareness of their BP status ( P  = 0.037). BP unawareness was associated with poor clinical prognosis, and could significantly increase stroke mortality ( P  = 0.001) and disability ( P < 0.001) rates as well as the duration of hospitalization ( P  < 0.001). Moreover, those who survived the stroke (modified Rankin Scale < 6) had the highest odds to be aware of their BP status (adjusted odds ratio [AOR] = 2.380 [95% confidence interval [CI] = 1.39-4.07]). Additionally, nonsmokers (AOR = 7.740), urban residents (AOR = 3.314), and literate patients (AOR = 2.092) had the highest odds of having appropriate drug adherence.

CONCLUSION

Stroke mortality and morbidity rates can be significantly modified by persuading people to monitor their BP regularly and maximize antihypertensive medication adherence. In the meantime, increasing the literacy level in society and reducing the smoking rate can play important roles in achieving these goals.

The effectiveness of nurse-led group interventions on hypertension lifestyle management: A mixed method study

PURPOSE

Hypertension is prevalent in Uganda and achieving treatment goals remains a challenge. Our aim was to assess the impact of a bundled nurse-led intervention on hypertension physiologic measures and lifestyle modification, and to explore perceptions of the interventions to enhance sustainability.

DESIGN AND SETTING

We employed a sequential explanatory mixed-method design. The study was conducted at a large urban private hospital in Uganda from September 2018 to May 2019.

SAMPLE

Participants were clinic patients with hypertension currently under care. A total of 54 participants were enrolled in two study groups. Two focus groups with 16 participants and 2 nurse-educator interviews were conducted.

METHODS

Blood pressure and weight were measured at baseline, three, six, and nine months. The Self-Care of Hypertension Inventory was used to assess lifestyle modification. Monthly education and group-support with text-message follow-up were implemented. Two focus-groups and nurse-educator interviews were conducted to assess perceptions post-implementation. The analysis included descriptive statistic, multivariate analysis and qualitative analysis for themes and subthemes.

FINDINGS

Overall, participants had a mean weight loss of 7.7 kg (p = 0.001) and a mean reduction in systolic blood pressure (SBP) of 9.5 mm Hg (p = 0.001). Improvement in biometric outcomes was associated with lifestyle modification such as taking medicine as prescribed (p = 0.008), eat lots of fruit and vegetables (p = 0.043), and control your body weight (p = 0.015). Thematic analysis yielded the following themes: Knowledge and understanding, Attitude change, Adherence-a real struggle, and Adapting to what suits us. Participants found group support, shared learning, and knowledge reinforcement enhanced their knowledge and self-efficacy. Nurse educators were motivated by the patients' favorable responses to the Bundled Education and Support with Text (BEST) intervention.

CONCLUSION

Findings support the use of nurse-led interventions to enhance the achievement of hypertension treatment goals. To sustain the achieved lifestyle modification and blood pressure outcomes, participants expressed a desire for continued support, information access, and inclusion of patients as champions for knowledge dissemination. Future studies need to explore the provision of enabling structures to support nurse-led interventions in routine non-Communicable disease (NCD) care.

CLINICAL RELEVANCE

Hypertension knowledge-gaps exist among patients and may reflect missed opportunities for patient engagement and education for behavior change. Bundled nurse-led hypertension interventions can significantly improve lifestyle modification and enhance hypertension outcomes. Persons supported and empowered with knowledge can act as conduits to wider communities in championing knowledge dissemination.

Predictors of Medication-Related Emergency Department Admissions Among Patients with Cardiovascular Diseases at Mbarara Regional Referral Hospital, South-Western Uganda

BACKGROUND

Medication-related emergency department admissions impose a huge and unnecessary burden on the healthcare system. We sought to determine the prevalence and predictors of medication-related emergency department admissions, among patients with cardiovascular diseases at Mbarara Regional Referral Hospital, Uganda.

METHODS

Institutional research ethics approval was secured to conduct a cross-sectional study at the Mbarara Regional Referral Hospital emergency department, between February and September, 2020. All eligible and consenting patients were enrolled in a consecutive manner after a preliminary diagnosis was made by the attending physician. Structured questionnaire interview and comprehensive medication history reviews were used to identify medication therapy problems, in collaboration with a resident physician present on duty. We used sequential categorization for medication therapy problem(s). Descriptive and logistic regression analyses were used to determine prevalence and predictors of medication-related emergency department admissions.

RESULTS

Out of the 128 patients interviewed, 105 (82%) patient admissions were associated with a medication therapy problem: ineffectiveness of drug therapy (53.3%, 56), medication non-adherence (42.9%, 45), and adverse drug reactions (3.8%, 4). Out of a total of 90 incidences of medication non-adherence, 34.4% (31/90) were due to lack of understanding of patient medication regimen, and 27.8% (25/90) due to unaffordable cost of medicines. Female gender (AOR = 4.31 [1.43, 13.03 at 95% CI]; P-value = 0.010]) and a history of tobacco use (AOR = 9.58 [1.14, 80.28 at 95% CI]; P-value = 0.037) were statistically significant predictors of medication-related emergency department admissions in adjusted analysis.

CONCLUSION

Four in five emergency department admissions were associated with medication-related causes, majorly due to ineffectiveness of drug therapy. Knowledge gap on patient medication regimens was the most prevalent cause for medication non-adherence. Female gender and previous or current tobacco use was an independent risk factor for medication-related admissions.

Prevalence and factors associated with behavioural problems in children with epilepsy attending Mulago hospital, Uganda: A cross-sectional study

PURPOSE

To determine the prevalence of behavioural problems and the associated factors in children with epilepsy (CWE).

METHODS

This was a cross-sectional study conducted at Mulago National Referral Hospital, Kampala, Uganda, from December 2019 to May 2020. A total of 300 CWE aged 6 to 17 years were consecutively enrolled and assessed for behavioural problems using the Strengths and Difficulties Questionnaire. We obtained data on the associated factors by using pretested structured questionnaires, the Rosenberg Self-Esteem Scale, the Kilifi Stigma Scale of Epilepsy, the Morisky medication adherence scale and the Tumaini Child Health Screener for childhood disabilities.  Simple logistic regression and multivariate analysis was done to determine the associated factors while adjusting for the presence of neurodevelopmental disorders and childhood disabilities.

RESULTS

Behavioural problems were detected in 108/300 CWE (36%) with more internalizing (28%) than externalizing (21%) behaviour scores noted. The odds of behavioural problems increased with the presence of co-morbid neurodevelopmental disorders or childhood disabilities (cOR: 5.42, p-value < 0.001). Factors associated with occurrence of behavioural problems were high stigma perception (aOR: 4.06, p-value < 0.001) and being seizure-free in the last six months (aOR: 3.43, p-value =0.031) while being an adolescent (aOR: 0.33, p=0.001) lessened the risk.

CONCLUSIONS

Behavioural problems occur in more than a third of CWE. They are more in the internalizing domain than in the externalizing domain. Their odds increase with high perceived stigma and in the first six months of seizure control.

Reasons for poor blood pressure control in Eastern Sub-Saharan Africa: looking into 4P's (primary care, professional, patient, and public health policy) for improving blood pressure control: a scoping review

AIM

Hypertension control in Sub-Saharan Africa (SSA) is the worst (less than one out of ten) when compared to the rest of the world. Therefore, this scoping review was conducted to identify and describe the possible reasons for poor blood pressure (BP) control based on 4Ps' (patient, professional, primary healthcare system, and public health policy) factors.

METHODS

PRISMA extension for scoping review protocol was used. We systematically searched articles written in the English language from January 2000 to May 2020 from the following databases: PubMed/Medline, Embase, Scopus, Web of Science, and Google scholar.

RESULTS

Sixty-eight articles were included in this scoping review. The mean prevalence of hypertension, BP control, and patient adherence to prescribed medicines were 20.95%, 11.5%, and 60%, respectively. Only Kenya, Malawi, and Zambia out of ten countries started annual screening of the high-risk population for hypertension. Reasons for nonadherence to prescribed medicines were lack of awareness, lack of access to medicines and health services, professional inertia to intensify drugs, lack of knowledge on evidence-based guidelines, insufficient government commitment, and specific health behaviors related laws. Lack of screening for high-risk patients, non-treatment adherence, weak political commitment, poverty, maternal and child malnutrition were reasons for the worst BP control.

CONCLUSION

In conclusion, the rate of BP treatment, control, and medication adherence was low in Eastern SSA. Screening for high-risk populations was inadequate. Therefore, it is crucial to improve government commitment, patient awareness, and access to medicines, design country-specific annual screening programs, and empower clinicians to follow individualized treatment and conduct medication adherence research using more robust tools.

Patient experiences and perspectives on hypertension at a major referral hospital in rural southwestern Uganda: a qualitative analysis

OBJECTIVES

Novel care models are needed to address the large burden of hypertension globally. We aimed to explore how patients in rural Uganda experience and perceive hypertension in order to understand factors that may inform development of a patient-centred care model for hypertension management in this setting.

DESIGN

We conducted one-time, in-depth qualitative interviews focusing on participants' experiences and perceptions of the meaning and management of hypertension.

SETTING

Outpatient clinic at Mbarara Regional Referral Hospital in Uganda.

PARTICIPANTS

We enrolled patients who had hypertension and had used antihypertensive medication for at least 1 month. We used purposive sampling to recruit 30 participants with similar representation by gender and by absence or presence of comorbid conditions.

RESULTS

Participants had been diagnosed and initiated care at various clinical stages of hypertension, which impacted their understanding of hypertension. Several participants saw hypertension as a chronic disease that can lead to complications if not controlled, while others attributed symptoms typically associated with other diseases to hypertension. Participants described inconsistent access to antihypertensive medications and difficulty with transport to the clinic (time needed and expense) as the major barriers to access to care. Initiation and maintenance of care were facilitated by family support and ready access to health facilities. Many participants identified an understanding of the important lifestyle and dietary changes required to control hypertension.

CONCLUSIONS

Patients with hypertension in rural Uganda demonstrated a varied understanding and experience with hypertension. Interventions leveraging family support may help with patient education and clinical management. Integration of patient perspectives into the care model, patient-centred care, may serve as a successful model for hypertension and potentially delivery of care for other non-communicable diseases in Uganda and other similar resource-limited settings.

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.

Predictors of 30-day and 90-day mortality among hemorrhagic and ischemic stroke patients in urban Uganda: a prospective hospital-based cohort study

Background

We report here on a prospective hospital-based cohort study that investigates predictors of 30-day and 90-day mortality and functional disability among Ugandan stroke patients.

Methods

Between December 2016 and March 2019, we enrolled consecutive hemorrhagic stroke and ischemic stroke patients at St Francis Hospital Nsambya, Kampala, Uganda. The primary outcome measure was mortality at 30 and 90 days. The modified Ranking Scale wasused to assess the level of disability and mortality after stroke. Stroke severity at admission was assessed using the National Institute of Health Stroke Scale (NIHSS) and Glasgow Coma Scale (GCS). Examination included clinical neurological evaluation, laboratory tests and brain computed tomography (CT) scan. Kaplan-Meier curves and multivariate Cox proportional hazard model were used for unadjusted and adjusted analysis to predict mortality.

Results

We enrolled 141 patients; 48 (34%) were male, mean age was 63.2 (+ 15.4) years old; 90 (64%) had ischemic and 51 (36%) had hemorrhagic stroke; 81 (57%) were elderly (≥ 60 years) patients. Overall mortality was 44 (31%); 31 (23%) patients died within the first 30 days post-stroke and, an additional 13 (14%) died within 90 days post-stroke. Mortality for hemorrhagic stroke was 19 (37.3%) and 25 (27.8%) for ischemic stroke. After adjusting for age and sex, a GCS score below < 9 (adjusted hazard ratio [aHR] =3.49, 95% CI: 1.39–8.75) was a significant predictor of 30-day mortality. GCS score < 9 (aHR =4.34 (95% CI: 1.85–10.2), stroke severity (NIHSS ≥21) (aHR = 2.63, 95% CI: (1.68–10.5) and haemorrhagic stroke type (aHR = 2.30, 95% CI: 1.13–4.66) were significant predictors of 90-day mortality. Shorter hospital stay of 7–13 days (aHR = 0.31, 95% CI: 0.11–0.93) and being married (aHR = 0.22 (95% CI: 0.06–0.84) had protective effects for 30 and 90-day mortality respectively.

Conclusion

Mortality is high in the acute and sub-acute phase of stroke. Low levels of consciousness at admission, stroke severity, and hemorrhagic stroke were associated with increased higher mortality in this cohort of Ugandan stroke patients. Being married provided a protective effect for 90-day mortality. Given the high mortality during the acute phase, critically ill stroke patients would benefit from early interventions established as the post-stroke- standard of care in the country.

Prevalence, Awareness, Treatment and Control of Hypertension in Nigeria: Data from a Nationwide Survey 2017

Background

Previous studies that evaluated the prevalence, awareness and treatment of hypertension in Nigeria were either localized to some specific regions of the country or non-standardized thereby making evaluation of trend in hypertension care difficult.

Methods

We used the World Health Organization (WHO) STEPwise approach to chronic disease risk factor surveillance to evaluate in a nationally representative sample of 4192 adult Nigerians selected from a rural and an urban community in one state in each of the six geo-political zones of the country.

Results

The overall age-standardized prevalence of hypertension was 38.1% and this varied across the geo-political zones as follows: North-Central, 20.9%; North-East, 27.5%; North-West, 26.8%; South-East, 52.8%; South-South, 44.6%; and South-West, 42.1%. Prevalence rate did not differ significantly (p > 0.05) according to place of residence; 39.2% versus 37.5 %; urban vs rural. Prevalence of hypertension increased from 6.8% among subjects less than 30 years to 63.0% among those aged 70 years and above. Awareness was better (62.2% vs. 56.6%; P = 0.0272); treatment rate significantly higher (40.9 % vs. 30.8%; P < 0.0001) and control similar (14 vs. 10.8%) among urban compared to rural residents. Women were more aware of (63.3% vs. 52.8%; P < 0.0001); had similar (P > 0.05) treatment (36.7 vs. 34.3%) and control (33.9% vs. 35.5%) rates of hypertension compared to men.

Conclusion

Our results suggest a large burden of hypertension in Nigeria and a closing up of the rural-urban gap previously reported. This calls for a change in public health policies anchored on a primary health care system to address the emerging disease burden occasioned by hypertension.

The outpatient management of hypertension at two Sierra Leonean health centres: A mixed-method investigation of follow-up compliance and patient-reported barriers to care

BACKGROUND

Sub-Saharan Africa faces an increasing burden of non-communicable diseases. In particular, hypertension and its therapeutic control present a challenge and opportunity for health practitioners and health systems within the region.

AIM

This study sought to assess an initiative conducted by two health clinics to begin treatment of hypertension amongst their patient populations by reviewing medication possession rates and documenting patient-reported barriers to care in the provision of chronic hypertension management.

SETTING

Two private, outpatient health clinics in Sierra Leone recently beginning hypertension management initiatives.

METHODS

A retrospective chart review identified 487 records of patients with diagnosed hypertension and assessed for medication adherence through calculation of medication possession ratios from pharmacy refill data. Surveys were conducted on a convenience sample of 68 patients of the hypertension treatment programme to discern patient-reported barriers of care.

RESULTS

Medication possession rates were found to be less than 40% in 82% (399/487) of patients, between 40% and 79% in 12% (60/487) of patients and 80% or greater in 6% (28/487) of patients. In surveys of individuals being treated by the programme, patients were most likely to cite transportation (81%, 55/68), financial burden (69%, 47/68) and schedule conflicts with work or other prior commitments (25%, 17/68) as barriers to care.

CONCLUSIONS

In this newly instituted outpatient hypertensive management initiative, 82% of patients had medication possession ratios under 40%, which is likely to impact the clinical effectiveness of the initiative. The most frequent patient-reported barriers to care in surveys included transportation, financial burden and schedule conflicts.

Adherence to Antihypertensive Medication: An Interview Analysis of Southwest Ugandan Patients' Perspectives

Background:

Hypertension is a significant cardiovascular disease (CVD) and driver to CVD disorders in sub-Saharan Africa. It is a major independent risk factor for heart failure, stroke, and kidney failure. Persons living with hypertension attend to many aspects of self-care to manage their condition, including high blood pressure medication adherence to control of blood pressure. Rates of medication non-adherence, and thus uncontrolled hypertension, remain high and contribute to poor health outcomes. Understanding barriers and facilitators to adherence to hypertension therapies can help improve health outcomes.

Objective:

The aim of the study was to describe the common reasons for adherence and non-adherence to antihypertensive medication from patients’ perspectives.

Methods:

A qualitative study engaged clients of an out-patient clinic of a regional referral hospital in southwestern Uganda who were living with hypertension as participants. One-on-one in-depth interviews provided the narrative data. The interview transcripts were analyzed using thematic analysis.

Findings:

Sixteen participants provided the data for the findings. The themes identified as facilitators for adherence to antihypertensive medication were patients’ understanding of prescribed medication, availability of medication for hypertension, family support for patients living with hypertension, and regular review appointments at the hypertensive clinics. Conversely, lack of supply in government dispensaries, use of self-prescribed analgesic medication, and stigma were identified as barriers and challenges of adherence to antihypertensive medication.

Conclusions:

There is an urgent need for the health ministry to improve availability of high blood pressure medication and for health care providers to deliver individualized patient centered care, and sensitization on danger of self-prescription and measures that reduce stigma. These strategies may improve adherence to high blood pressure medication.

Assessing Providers' Approach to Hypertension Management at a Large, Private Hospital in Kampala, Uganda

Background:

Hypertension is increasingly prevalent in Uganda and its clinical management remains suboptimal across the country. Prior research has elucidated some of the factors contributing to poor control, but little is known about providers’ approaches to hypertension management and perceptions of barriers to care. This is particularly true in private health care settings – despite the fact that the private sector provides a substantial and growing portion of health care in Uganda.

Objective:

Our exploratory, pragmatic qualitative study aimed to examine the factors affecting the quality of hypertension care from the perspective of providers working in an urban, private hospital in Uganda. We focused on the organizational and system-level factors influencing providers’ approaches to management in the outpatient setting.

Methods:

We conducted interviews with 19 health care providers working in the outpatient setting of a 110-bed, private urban hospital in Kampala, Uganda. We then coded the interviews for thematic analysis, using an inductive approach to generate the study’s findings.

Findings:

Several themes emerged around perceived barriers and facilitators to care. Providers cited patient beliefs and behaviors, driven in part by cultural norms, as a key challenge to hypertension control; however, most felt their own approach to hypertension treatment aligned with international guidelines. Providers struggled to collaborate with colleagues in coordinating the joint management of patients. Furthermore, they cited the high cost and limited availability of medication as barriers.

Conclusions:

These findings offer important strategic direction for intervention development specific to this Ugandan context: for example, regarding culturally-adapted patient education initiatives, or programs to improve access to essential medications. Other settings facing similar challenges scaling up management of hypertension may find the results useful for informing intervention development as well.

Assessment of post discharge medication prescription among Lebanese patients with cerebral infarction: Results of a cross-sectional study

OBJECTIVES

The study objective was to investigate the degree of physician adherence with the international guidelines for post-stroke discharge medications among Lebanese hospitals.

PATIENT AND METHODS

This retrospective observational study was conducted in three Lebanese hospitals between January 2016 and December 2017.

RESULTS

Out of 200 patients with stroke, 64.7 % were males. The difference of systolic blood pressure from baseline, 2 h, and after 24 h showed significant decrease by mean value 25.18 ± 33.45 (P < 0.001), and 6.44 ± 22.11 (P = 0.019) respectively. Also diastolic blood pressure showed significant decrease between baseline and after 24 h by a mean value 12.17 ± 13.63 (P value <0.001). Concerning post discharge medications adherence, antithrombotic drugs showed the highest percentage (73 %) followed by antihypertensive and lipid lowering agents by comparable results (47.5 % and 40.7 % respectively). The physician adherence for the three medications together showed (30.4 %).

CONCLUSION

Secondary prevention for critical diseases such as stroke appears to be inadequate in the study area.

Determinants of adherence to anti-hypertensive medications among adult hypertensive patients on follow-up in Hawassa Referral Hospital: A case-control study

Introduction

Hypertension is a global challenge which accounts for high morbidity and mortality rates in the world. The availability of effective anti-hypertensive medications does not result in a good outcome in controlling blood pressure which points towards poor adherence. Thus, this study was conducted to assess the determinants of adherence to anti-hypertensive medication among hypertensive patients on follow-up in Hawassa Referral Hospital.

Methods

Institution-based case-control study was conducted on a sample of 289 clients from February to May 2018. Census was conducted on 1600 clients to select cases and controls. Then, systematic random sampling was used to select study subjects, and adherence was measured by Morisky medication adherence scale. The associations of variables were analyzed using bivariable followed by multivariable logistic regression analyses.

Results

The respondent's adherence to medication was found to be 67% as measured by Morisky medication adherence scale. The multivariate logistic regression analysis showed that medication adherence was found to be better in younger age (<45) (AOR = 3.8), clients living in urban areas (AOR = 6.84), those clients who had good knowledge (AOR = 3.13), those with no co-morbidities (AOR = 3.14) and patients who controlled their blood pressure (<140/90) (AOR = 2.35).

Conclusions

The rate of medication adherence was found to be low, and hence educational interventions focusing on factors promoting adherence and patients' health support should be implemented.

Frequency of Medication Non-compliance in Hypertensive Patients Presenting with Stroke: A Case-control Study

Introduction

Medication compliance (MC) is essential for optimum control and delaying disease progression and complications in chronic illnesses. Patients with hypertension have been repeatedly studied for their pattern of MC in the literature. However, whether or not lack of MC is an issue grave enough to cause medical complications of hypertension is still not clear. The aim of this study was to evaluate if the lack of MC is related to hypertension-related stroke.

Methods

In this case-control, observational study, 100 hypertensive patients admitted with hypertensive stroke were included. These cases were compared with 200 hypertensive patients without any major hypertensive complication recruited from outpatient clinics. Medication compliance was calculated using the Morisky Medication Adherence Scale (MMAS). Data was entered and analysed using SPSS v. 22.0.

Results

High compliance patients were more in the control group than the cases (34.5% vs. 27%), similar was with medium (41.5% vs. 30%). and low compliance patients (43% vs. 24%; p = 0.003). In both high compliant and moderate-to-low compliant group, mean systolic and diastolic blood pressure was higher among the cases (p <0.05). Among high compliant patients, cases were taking more pills per day than the controls (p = 0.032). Among moderate-to-low compliant patients, 80% perceived themselves to be highly compliant and only 20% perceived to be low complaint in the cases, as compared to 60% controls perceiving themselves compliant and 40% as low complaint (p = 0.001).

Conclusion

The incidence of low medication adherence is significantly higher in patients with major hypertensive complications such as stroke as compared to hypertensive patients without any major complication.

Prevalence, patterns and factors associated with hypertensive crises in Mulago hospital emergency department; a cross-sectional study

Background

Hypertension is increasing in sub-Saharan Africa (SSA) and it's the single most important modifiable stroke risk factor, yet it's control is not routinely emphasized.

The prevalence, pattern and factors associated with hypertensive urgencies and emergencies in Uganda is not well established. A cross-sectional study, was conducted between November 2015 and February 2016, using a complete clinical examination and pre-tested standardized questionnaire subjects were enrolled. The prevalence of hypertensive crises and associations of demographic and clinical factors determined using logistic regression.

Results

The prevalence of hypertensive crises was 5.1%, (203/4000) of all admissions at the medical section of the accident and emergency ward of Mulago National Referral Hospital. The hypertensive urgencies and emergencies accounted for 32.5% and 67.5% respectively among study subjects with hypertension. Among those with hypertensive crises, 41.1% were aged 45–65 years and half were female. Self-reported compliance was significantly different between those with hypertensive crisis compared to non-hypertensive crisis with OR; (95% CI) 52.4; (24.5 — 111.7), p-value =<0.001. Acute stroke was the commonest hypertensive emergency.

Conclusion

Hypertensive emergencies are common and significantly associated with poor compliance to prescribed anti-hypertensive drugs. Acute stroke is the commonest presentation in our setting.

Stroke care in Africa: A systematic review of the literature

Background

Appropriate systems of stroke care are important to manage the increasing death and disability associated with stroke in Africa. Information on existing stroke services in African countries is limited.

Aim

To describe the status of stroke care in Africa.

Summary of review

We undertook a systematic search of the published literature to identify recent (1 January 2006–20 June 2017) publications that described stroke care in any African country. Our initial search yielded 838 potential papers, of which 38 publications were eligible representing 14/54 African countries. Across the publications included for our review, the proportion of stroke patients reported to arrive at hospital within 3 h from stroke onset varied between 10% and 43%. The median time interval between stroke onset and hospital admission was 31 h. Poor awareness of stroke signs and symptoms, shortages of medical transportation, health care personnel, and stroke units, and the high cost of brain imaging, thrombolysis, and outpatient physiotherapy rehabilitation services were reported as major barriers to providing best-practice stroke care in Africa.

Conclusions

This review provides an overview of stroke care in Africa, and highlights the paucity of available data. Stroke care in Africa usually fell below the recommended standards with variations across countries and settings. Combined efforts from policy makers and health care professionals in Africa are needed to improve, and ensure access, to organized stroke care in as many settings as possible. Mechanisms to routinely monitor usual care (i.e., registries or audits) are also needed to inform policy and practice.

Prevalence and risk factors for prehypertension and hypertension among adults in Central China from 2000-2011

BACKGROUND

Hypertension is frequently studied in surveys; however, prehypertension, a new blood pressure status between normotension and hypertension, is rarely reported.

METHODS

All data were derived from the China Health and Nutrition Survey (CHNS) and were analysed by logistic regression for correlation.

RESULTS

The prehypertension prevalence was 27.4%, with a hypertension rate of 36.9%. The awareness, treatment, and uncontrolled rates among all hypertension participates were 19.8%, 83.6%, and 55.0%, respectively. The epidemic rate of hypertension increased with increasing age (p < 0.001), and prehypertension appeared to have an epidemic peak in the age group of 38-57 years (p < 0.001). In general, the incidence of hypertension in urban participants was higher than in rural subjects (p < 0.001), and prehypertension in urban subjects was lower than that in rural subjects (p < 0.001). According to the results of logistic regression, hypertension and prehypertension were associated with age, gender, location, body mass index (BMI), body fat rate (BFR), waist circumference (WC), education, and the intake of energy-yielding nutrients<0.05).

CONCLUSION

The current study reveals a high epidemic rate of hypertension and prehypertension in Central China. These results indicate the urgent need to develop strategies to improve the prevention of hypertension and prehypertension in Central China.

Modifiable lifestyle risk factors for stroke among a high risk hypertensive population in Greater Kampala, Uganda; a cross-sectional study

OBJECTIVE

To describe the modifiable lifestyle risk factors for stroke among a high risk population for stroke. Africa suffers from rapid population growth, adoption of harmful western diets, and increased prevalence of hypertension and obesity.

RESULTS

A total of 440 study participants were screened and 87 individuals with hypertension plus at least one other known stroke risk factor were enrolled. The prevalence of hypertension and diabetes mellitus in the screened population was 19.7 and 1.8%, respectively. Among those with hypertension only 2.3% (2/87) had ever had serum lipid assessment. Seventy-two percent (68/87) had very high serum LDL-cholesterol, while 33.3% (29/87) had low levels of HDL-cholesterol, and 67.8% had mean blood pressures greater than 160/100 mmHg and 40% (35/87) were obese, with a BMI ≥30. Targeting individuals with modifiable stroke risk factors and implementing self-management programs may be a way to reduce stroke burden in Uganda.

Assessing Adherence to Antihypertensive Therapy in Primary Health Care in Namibia: Findings and Implications

INTRODUCTION

Namibia has the highest burden and incidence of hypertension in sub-Sahara Africa. Though non-adherence to antihypertensive therapy is an important cardiovascular risk factor, little is known about potential ways to improve adherence in Namibia following universal access. The objective of this study is to validate the Hill-Bone compliance scale and determine the level and predictors of adherence to antihypertensive treatment in primary health care settings in sub-urban townships of Windhoek, Namibia.

METHODS

Reliability was determined by Cronbach's alpha. Principal component analysis (PCA) was used to assess construct validity.

RESULTS

The PCA was consistent with the three constructs for 12 items, explaining 24.1, 16.7 and 10.8% of the variance. Cronbach's alpha was 0.695. None of the 120 patients had perfect adherence to antihypertensive therapy, and less than half had acceptable levels of adherence (≥ 80%). The mean adherence level was 76.7 ± 8.1%. Three quarters of patients ever missed their scheduled clinic appointment. Having a family support system (OR = 5.4, 95% CI 1.687-27.6, p = 0.045) and attendance of follow-up visits (OR = 3.1, 95% CI 1.1-8.7, p = 0.03) were significant predictors of adherence. Having HIV/AIDs did not lower adherence.

CONCLUSIONS

The modified Namibian version of the Hill-Bone scale is reliable and valid for assessing adherence to antihypertensives in Namibia. There is sub-optimal adherence to antihypertensive therapy among primary health cares in Namibia. This needs standardized systems to strengthen adherence monitoring as well as investigation of other factors including transport to take full advantage of universal access.

Prevalence, awareness, and associated risk factors of hypertension in older adults in Africa: a systematic review and meta-analysis protocol

BACKGROUND

The health of older persons has not been a major priority in many African countries. Hypertension is one of the common health problems of older persons. However, there is little information on the prevalence of hypertension in older adults in Africa. This is in spite of the fact that Africa has the highest age-standardized prevalence of hypertension in the world. We therefore present this protocol to conduct a systematic review and meta-analysis on the prevalence of hypertension and the level of its awareness among older persons living in Africa.

METHODS

Major databases (EMBASE, MEDLINE, Academic Search Complete, CINAHL, PsycINFO) and unpublished literature will be searched to identify population-based studies on hypertension in adults aged 50 years and older living in Africa. Eligible articles are those which use the 140/90-mmHg cutoff to diagnose hypertension and were published from 1980 to present. We will exclude subjects in restricted environments such as patients and refugees. Articles will be independently evaluated by two reviewers to determine if they meet the inclusion criteria. They will also evaluate the quality of included studies using a validated tool by Hoy and colleagues for prevalence studies. The main outcome is the prevalence of hypertension while the explanatory variables include demographic, socio-economic, dietary, lifestyle and behavioural factors. Effect sizes in bivariate and multivariate analyses will be presented as odds or prevalence ratios. We will explore for heterogeneity of the standard errors across the studies, and if appropriate, we will perform a meta-analysis using a random-effects model to present a summary estimate of the prevalence of hypertension in this population.

DISCUSSION

The estimates of the prevalence, the risk factors and the level of awareness of hypertension could help in galvanizing efforts at prioritizing the cardiovascular health of older persons in Africa.

Nonadherence to antihypertensive drugs: A systematic review and meta-analysis

BACKGROUND

Hypertension drives the global burden of cardiovascular disease and its prevalence is estimated to increase by 30% by the year 2025. Nonadherence to chronic medication regimens is common; approximately 43% to 65.5% of patients who fail to adhere to prescribed regimens are hypertensive patients. Nonadherence to medications is a potential contributing factor to the occurrence of concomitant diseases.

OBJECTIVE

This systematic review applied a meta-analytic procedure to investigate the medication nonadherence in adult hypertensive patients.

METHODS

Original research studies, conducted on adult hypertensive patients, using the 8-item Morisky medication adherence scale (MMAS-8) to assess the medication adherence between January 2009 and March 2016 were included. Comprehensive search strategies of 3 databases and MeSH keywords were used to locate eligible literature. Study characteristics, participant demographics, and medication adherence outcomes were recorded. Effect sizes for outcomes were calculated as standardized mean differences using random-effect model to estimate overall mean effects.

RESULTS

A total of 28 studies from 15 countries were identified, in total comprising of 13,688 hypertensive patients, were reviewed. Of 25 studies included in the meta-analysis involving 12,603 subjects, a significant number (45.2%) of the hypertensive patients and one-third (31.2%) of the hypertensive patients with comorbidities were nonadherent to medications. However, a higher proportion (83.7%) of medication nonadherence was noticed in uncontrolled blood pressure (BP) patients. Although a higher percentage (54%) of nonadherence to antihypertensive medications was noticed in females (P < 0.001), the risk of nonadherence was 1.3 times higher in males, with a relative risk of 0.883. Overall, nearly two-thirds (62.5%) of the medication nonadherence was noticed in Africans and Asians (43.5%).

CONCLUSION

Nonadherence to antihypertensive medications was noticed in 45% of the subjects studied and a higher proportion of uncontrolled BP (83.7%) was nonadherent to medication. Intervention models aiming to improve adherence should be emphasized.

Post-discharge evaluation of medication adherence and knowledge of hypertension among hypertensive stroke patients in northwestern China

OBJECTIVES

The aims of this study were to assess the knowledge of hypertension (HTN) and investigate risk factors associated with medication adherence among hypertensive stroke patients after discharge in northwestern China.

PATIENTS AND METHODS

A cross-sectional study involving 440 Chinese hypertensive stroke patients was conducted in a tertiary hospital in Xi'an, China. Data were collected by telephone interviews and patients' medical records.

RESULTS

It was found that 35.23% of patients were compliant with their antihypertensive drug treatments, and 42.95%, 52.27% and 4.77% of patients had poor, moderate and adequate knowledge of HTN, respectively. Gender, blood pressure (BP) categories, BP monitoring and HTN knowledge were independently associated with antihypertensive medication adherence.

CONCLUSION

The medication adherence among hypertensive stroke patients in northwestern China was poor. Knowledge of HTN was suboptimal. More attention and effective strategies should be designed to the factors affecting medication adherence. As knowledge positively affects medication adherence, clinical pharmacists should play an important role in patients' medication education.
