Drug therapy, lifestyle modification and blood pressure control in a primary care facility, south of Johannesburg, South Africa: an audit of hypertension management

Blood Pressure Control and Associated Factors among Hypertension Comorbid Type 2 Diabetic Patients in Southeast Ethiopia

Background

Hypertension is the main contributor to the morbidity and mortality of patients with cardiovascular disease. Even though hypertension is very common in comorbid type 2 diabetic patients, it is frequently overlooked. This study aimed to assess blood pressure control and its associated factors among hypertension comorbid type 2 diabetic patients in Bale Zone public hospitals in Southeast Ethiopia.

Methods and Materials

A hospital-based cross-sectional study design was conducted among hypertension comorbid type 2 diabetic patients. The data were collected using an interviewer-administered structured questionnaire and a review of the medical charts of patients. A simple random sampling technique was used to select the study participants. The bivariate and multivariate logistic regression analyses were performed to assess the association between blood pressure control and its associated factors. Independent variables that showed a P < 0.25 in the bivariate analysis was included in the multivariate analysis. Finally, variables with a P < 0.05 were declared statistically significant factors.

Results

The total number of participants in the study was 378. The overall magnitude of uncontrolled hypertension among hypertension comorbid diabetic patients was found to be 82.5% (95% CI: 78.7%, 86.4%). Nonadherence to antihypertensive medication (AOR = 2.45, 95% CI: 1.11, 5.39, P = 0.027), duration of hypertension >10 years (AOR = 5.2, 95% CI: 1.27, 21.38, P = 0.022), participants who attended secondary education (AOR = 3.2, 95% CI: 1.18, 8.87, P = 0.023), and being obese (AOR = 4.1, 95% CI: 1.24, 13.49, P = 0.021) were significantly associated with uncontrolled hypertension.

Conclusion

Uncontrolled hypertension was found to be high among hypertension comorbid type 2 diabetic patients. Patients' adherence to antihypertensive medication, physical activity, and alcohol abstinence should be maximized. Loss of weight is also crucial, as is the early detection and management of comorbidities.

Uncontrolled blood pressure and associated factors in adult hypertensive patients undergoing follow-up at public health facility ambulatory clinics in Bishoftu town, Ethiopia: a multi-center study

BACKGROUND

Uncontrolled blood pressure is an important medical and public health problem in developing countries like Ethiopia. Improving the management of hypertension requires a better comprehension of the factors influencing blood pressure control and the application of interventions. But in clinical practice, blood pressure is still not adequately controlled. Thus, this study aimed to assess uncontrolled blood pressure and associated among adult hypertensive patients on follow-up at public health facility ambulatory clinics in Bishoftu, Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted among 398 adult hypertensive patients who were on treatment and follow-up from April to May 31, 2022. Systematic random sampling was used to select study participants. Data were collected using an interviewer-administered, semi-structured questionnaire and chart review. The Eighth Joint National Committee (JNC 8) criteria was applied to define blood pressure control status. Binary logistic regression analysis was used to model the association between dependent and independent variables. An adjusted odds ratio and 95% confidence interval were used to measure the strength of the association. Finally, at a p-value < 0.05, statistical significance was proclaimed.

RESULT

Of the total study participants, 249(62.6%) were male. The mean age was 62.26 ± 11.55 years. The overall proportion of uncontrolled blood pressure was 58.8% (95% CI: 54-64). Salt intake (AOR = 2.51; 95% CI: 1.49-4.24), lack of physical activity (AOR = 1.40; 95% CI: 1.10-2.62), habitual coffee consumption (AOR = 4.52; 95% CI: 2.67-7.64), higher BMI (AOR = 2.08; 95% CI: 1.24-3.49), and non-adherence to antihypertensive medications (AOR = 2.31; 95% CI: 1.3-3.89) were independent predictors of uncontrolled blood pressure.

CONCLUSION

More than half of the hypertensive patients in this study had uncontrolled blood pressure. Healthcare providers and other accountable stakeholders should urge patients to follow salt restriction, physical activity, and antihypertensive medication regimes. Reduced coffee consumption and weight maintenance are other crucial blood pressure control measures.

Knowledge, attitude and practices of lifestyle modification and associated factors among hypertensive patients on-treatment follow up at Yekatit 12 General Hospital in the largest city of East Africa: A prospective cross-sectional study

BACKGROUND

Hypertension is a devastating global public health challenge; studies indicated that Ethiopia has been affected by the burden of hypertension especially in urban areas. The overall prevalence of hypertension in Ethiopia was estimated to be 19.6% (23.5% in urban and 14.7% in rural population). Along with medical management of hypertension, appropriate lifestyle modification is a crucial and inexpensive means of hypertension control. The main purpose of the study was therefore to assess knowledge, attitude and practice of lifestyle modification among patients on follow up for hypertension treatment at Yekatit 12 General Hospital.

METHODS

A prospective cross-sectional study design was applied in Yekatit 12 General Hospital from October 28, 2018, to February 28, 2019, by allotting proportionate samples from the two chronic outpatients departments (OPD). Using single proportion sampling techniques, the study participants were selected and the total sample size calculated was 405. Primarily, clinical measurements were made according to the international standard set to verify true hypertensive patient's inclusions. Then, data about socio-demographic characteristics, lifestyle modification related to knowledge, attitude and practices were comprehensively collected using an interviewer-administered structured questionnaire. The collected data was entered into Epi-data exported to SPSS Window version of 22 for analysis. All variables with ρ-value less than 0.05 in the final model were considered as independently associated with knowledge, attitude and practices of patients' lifestyle modification. The strength of association was described by Odds Ratio (OR) at the corresponding CI of 95%.

RESULTS

The overall sampled hypertensive patients as compared to the planned sample size was 95.5% (n = 387), out of which 53.5% (n = 207) was male patients. The mean age was 50 years with a standard deviation of 14.4. The study revealed that 67.7% [95% CI (65.32%, 70.08%)] were knowledgeable; and 54.0% [95% CI (51.34%, 56.6%)] were reported to have favorable attitude towards lifestyle modification. Regarding their practices, 38% [95% CI (19.91%, 57.49%] of the respondents had good practices. Their monthly income [AOR = 2.39, 95% CI (1.12, 5.11)] and duration on-treatment follow up since diagnosed with hypertension [AOR = 4.39, 95% CI (1.20, 16.03)] were independently associated with knowledge. Concerning their damned practices, age [AOR = 7.71, 95% CI (2.4, 24.8)] and knowledge [AOR = 3.94, 95% CI (2.01, 7.72)] were independently associated with the practices.

CONCLUSION

Though the encouraging high knowledge status and favourable attitudes towards lifestyle modification among hypertensive patients, the practices are among the lowest findings report in all standards. Hence, older patients, jobless patients, and low-income patients and patients on long-term treatment follow up who were diagnosed with hypertension before 10 years needs special attention and interventions by the country NCDs policy formulators to rise their non-pharmacological practices to control high blood pressure and its consequences.

Blood pressure control in hypertensive patients attending a rural community health centre in Gauteng Province, South Africa: A cross-sectional study

Background

Hypertension is a major cause of morbidity and mortality and its control has important clinical and socio-economic benefits to the family and community. Unfortunately, the extent of blood pressure (BP) control and its potential predictors in hypertensive patients in many rural communities in low-resource settings are largely unknown. This study assessed the extent of uncontrolled BP and its predictors amongst hypertensive patients accessing primary health care in a rural community in South Africa.

Methods

This cross-sectional study included 422 randomly selected hypertensive patients. Demographic and clinical data were collected using structured face-to-face questionnaire supplemented by respondents’ clinical records.

Results

Obesity plus overweight (n = 286, 67.8%) and diabetes (n = 228, 54.0%) were the most common comorbidities. Treatment adherence was achieved in only 36.3% and BP was controlled to target in 50.2% of the respondents. Significant predictors of uncontrolled BP were poor treatment adherence (odds ratio [OR] = 15.88, 95% confidence interval [CI] = 8.96, 28.14, p < 0.001), obesity compared with normal weight and overweight (OR = 3.75, 95% CI = 2.17, 6.46, p < 0.001) and being a diabetic (OR = 2.83, 95% CI = 1.74, 4.61, p < 0.001).

Conclusion

Poor adherence to treatment was the major predictor of uncontrolled BP. The increase in uncontrolled BP in the presence of diabetes and/or obesity as risk predictors, indicates the need for appropriate behaviour change/interventions and management of these conditions in line with the health belief model (HBM). We also propose the use of Community-Based Physical and Electronic Reminding and Tracking System (CB-PERTS) to address poor treatment adherence.

Blood Pressure Control, Left Ventricular Hypertrophy and Treatment Practice Among Hypertensive Patients in Ethiopia

Background

Globally, hypertension is the most important public health issue and is a increasing health problem in Ethiopia. Blood pressure (BP) control is an ultimate therapeutic goal of hypertensive patients in reducing early complications of hypertension. Hence, this study was sought to examine the magnitude of uncontrolled BP, left ventricular hypertrophy (LVH), and treatment practice. Predictors of uncontrolled BP and LVH were also investigated.

Methods

A hospital-based cross-sectional study was conducted among 223 outpatients with hypertension on follow-up at Ayder Comprehensive Specialized Hospital (ACSH). Hypertensive patients with ≥18 years old who had been on follow-up care for at least 3 months were included in the study. Severely ill patients requiring urgent medical care and wheelchair-bound individuals or persons who had difficulty standing steady and pregnant women were excluded. Data were collected using a structured questionnaire and patients’ chart review. Data were entered and analyzed using SPSS version 22.0. To identify predictors, binary logistic regression model analysis was performed. Statistical significance was set at P-value of < 0.05.

Results

The magnitude of uncontrolled BP (>140/90mmgH) and LVH was found to be 31.4% and 39.5%, respectively. More than half (53%) of participants were on at least two antihypertensive drug combinations of different classes. Uncontrolled BP was significantly associated with poor adherence to salt reduction in meal (Adjusted Odds Ratio (AOR) =8.552, 95% CI: 2.853, 15.638, P<0.001), non-adherence to medications (AOR =2.886, 95% CI: 1.710, 3.935, P<0.001), and taking triple-drug therapy (AOR=7.228, 95% CI: 1.110, 10.57, P=0.039). Presence of LVH was significantly associated with abdominal obesity (AOR= 2.2, 95% CI: 1.399, 4.69, P=0.003), age of ≥60 years (AOR= 2.421, 95% CI: 1.263, 4.639, P=0.008), and uncontrolled BP (AOR= 3.16, 95% CI: 1.208, 5.232, P=0.021).

Conclusion

In this study, a significant proportion of patients with uncontrolled BP and LVH were found. Abdominal obesity, older age and uncontrolled blood pressure were predictors of LVH. Therefore, tailored interventions targeting BP control to reduce the magnitude of LVH and other early complications of hypertension deemed to be compulsory.

Blood pressure control practice and determinants among ambulatory hypertensive patients attending primary health care facilities in Addis Ababa

Background:

Hypertension is the major risk factor for cardiovascular diseases related morbidity and mortality. Blood pressure is often not adequately controlled in clinical practice. Information regarding blood pressure control in primary care settings is limited in Ethiopia.

Objectives:

This study aimed to assess blood pressure control practice and determinates among hypertensive patients attending primary health care facilities in Addis Ababa.

Methods:

A cross-sectional study was conducted on 616 hypertension patients in 12 health centers in Addis Ababa city. Data were collected by interviewing patients and reviewing their medical records. Data were collected from 3 August to 30 October 2015.

Results:

A complete information was obtained from 616 patients’ medical records, and patients were then interviewed. The mean age was 58.90 (SD ± 13.04) years, and most of them (n = 321, 52.1%) were 60 years old or above, and more than three-fourth (n = 485) were on monotherapy. Methyldopa was the most monotherapy medication prescribed, 128 (20.8%). Only 31% (n = 191) of the patients had controlled blood pressure. Determinants for poor blood pressure control were age less than 60 years (adjusted odds ratio (AOR) = 3.06, 95% confidence interval (CI): 1.96, 4.78); work status: government employee (AOR = 2.41, 95% CI: 1.18, 4.90), retired (AOR = 1.79, 95% CI: 1.01, 3.18), and private business (AOR = 2.09, 95% CI: 1.17, 3.74); and being hypertensive for 10 or more years (AOR = 1.96, 95% CI: 1.11, 3.43). Significant predictors of achieving controlled blood pressure were weekly blood pressure measurement practice (AOR = 0.57, 95% CI: 0.36, 0.90) and tertiary-level education (AOR = 0.26, 95% CI: 0.13, 0.54).

Conclusions:

Only one-third of the patients had controlled blood pressure. Efforts should be made to address identified determinants including age, regular blood pressure monitoring practice, and level of education.

Blood Pressure Control among Hypertensive Diabetic Patients on Follow-Up at Chronic Clinic of Nekemte Referral Hospital in West Ethiopia

Background

Hypertension is a prevalent comorbid condition in diabetes, affecting ∼20–60% of patients with diabetes, depending on obesity, ethnicity, and age. Adults with diabetes historically have two or three times higher rate of cardiovascular disease (CVD) than adults without diabetes.

Objective

The aim of this study was to assess blood pressure (BP) control and its predictors among hypertensive diabetic patients on follow-up at the chronic clinic of Nekemte Referral Hospital (NRH) in West Ethiopia.

Methods

A cross-sectional study was conducted among hypertensive adult patients comorbid with diabetes taking antihypertensive drugs for at least one year in NRH. Both bivariable and multivariable analyses were done. The odds ratio, along with 95% confidence level, was estimated to identify factors associated with uncontrolled BP by using multivariable logistic regression analysis. The level of statistical significance was declared at p value <0.05 levels. The patient's written informed consent was obtained after explaining the purpose and procedures of the study.

Results

A total of 186 study participants were included in this study. The mean age of the participants was 51.2 ± 12.2 years. Blood pressure and blood glucose were controlled in 104 (55.9%) and 106 (57.0%) study participants, respectively. In the multivariable analysis, age ≥60 years (AOR = 4.537, 95% CI = 1.142–18.024, p=0.032), duration with hypertension ≥5 years (AOR = 3.534, 95% CI = 1.062–11.760, p=0.040), cigarette smoking (AOR = 7.697, 95% CI = 2.356–25.146, p=0.001), nonadherence (AOR = 6.584, 95% CI = 2.337–18.553, p < 0.001), and uncontrolled glycaemia (AOR = 21.630, 95% CI = 8.057–58.070, p < 0.001) were independent predictors of uncontrolled blood pressure.

Conclusion

Compared to the previous studies, BP was better controlled among hypertensive diabetic patients in the present study. Older age, longer duration with hypertension, cigarette smoking, nonadherence, and uncontrolled glycaemia were predictors of uncontrolled BP. Thus, interventions on modifiable factors should be done to improve BP control of patients' comorbid with diabetes.

Magnitude and Determinants of Uncontrolled Blood Pressure Among Adult Hypertensive Patients on Follow-Up at Nekemte Referral Hospital, Western Ethiopia

Background

Hypertension is the leading cause of morbidity and mortality among non-communicable diseases. The rate of blood pressure (BP) control among hypertensive patients is poor and the reasons for poor control of BP remain poorly understood globally. Therefore, this study aimed to assess the magnitude and determinants of uncontrolled blood pressure among adult hypertensive patients on follow-up at Nekemte referral hospital (NRH).

Methods

A hospital-based cross-sectional study was conducted from February to April 2018 at NRH. BP control status was determined by the average consecutive BP recordings across the 3 months. The data was entered and analyzed using SPSS version 20.0 and p-value <0.05 was considered statistically significant.

Results

Out of 297 study participants included, the majority were females, 181 (60.9%), and the mean age of the patients was 59.4 ±10.4 years. About half, 137 (46.12%), of the patients had at least one comorbidity and the most common class of anti-hypertensive medication was angiotensin-converting enzyme inhibitors (88.2%). The mean of systolic blood pressure was 132.41± 15.61mmHg, while the mean of diastolic blood pressure was 84.37± 9.32 mmHg. The proportion of participants with optimally controlled BP was 63.6% and 36% were adherent to their medications. Male sex (Adjusted Odd Ratio [AOR]: 1.89, 95% CI: 1.09-4.84), illiteracy (AOR= 1.56, 95% CI: 1.22-6.78), duration of hypertension diagnosis > 10 years (AOR= 2.01, 95% CI: 1.04-16.11), non-adherence (AOR= 3.14, 95% CI: 1.35-10.76) and lack of physical exercise (AOR= 2.8, 95% CI: 1.16-6.74) were positively associated with uncontrolled BP status. Whereas age older than 55 years (AOR= 0.38, 95% CI: 0.11-0.92) was negatively associated with uncontrolled BP.

Conclusion

BP control was relatively achieved in about two-third of pharmacologically treated patients. We recommend better health education and care of patients to improve the rate of BP control status.

Blood pressure control and burden of treatment in South African primary healthcare: A cross-sectional study

Background

Poor blood pressure (BP) control has been associated with high burden of treatment (BOT) in several settings. It is not known whether this relationship holds true for South African primary care.

Aim

The aim of this study was to assess BOT and determine its relationship with BP control amongst patients with hypertension in a large community health centre, south of Johannesburg.

Setting

The setting of this study was carried out in the OPD of Johan Heyns Community Health Center.

Methods

A cross-sectional study involving 239 patients with hypertension was carried out. Information on sociodemography and BP readings in the last 3 months were extracted from patient medical records. A researcher-administered treatment burden questionnaire was also used to collect information on participants’ perceptions of BOT relating to medication regimen, navigating the healthcare system and life style changes and/or social and/or financial issues. Total BOT (TBOT) was determined as the sum of the scores in the three components and categorised as 1–45 = low, 46–90 = moderate and 91–140 = high. Analysis included descriptive statistics and test of association.

Results

Most participants were white (54.2%), > 55 years (52.9%), female (60.1%), married (56.3%), had grade 12 or more education (71.9%) and had no comorbidity (56.7%). The mean duration of hypertension treatment was 113.8 months and most participants were uncontrolled (60.1%). Most participants (75%) reported a low TBOT score, with a mean of 19.7. Amongst participants with clinical comorbidities, most (66.3%) did not consider hypertension to be more burdensome than other comorbid illnesses. There was no significant association between TBOT and BP control (p = 0.53). However, participants with a high BOT relating to medication regimen were significantly more likely to be uncontrolled (p = 0.04).

Conclusion

Total BOT is low amongst study participants and has no significant influence on BP control. However, improvements in BP control in South African primary healthcare may be hinged on interventions that address problems associated with hypertension medication regimen.

Assessment of hypertension control and factors associated with the control among hypertensive patients attending at Zewditu Memorial Hospital: a cross sectional study

Objective

This study was conducted to assess hypertension control and factors associated with it among hypertensive patients on treatment at Zewditu Memorial Hospital.

Results

A total of 225 patients were included in the study, of which 55.6% of patients were females. The mean age of the patients was 55.2 years and half of them had a family history of hypertension. About 29% of patients had comorbidities. Angiotensin-converting enzyme inhibitors (ACEIs), calcium channel blockers (CCBs) and beta-blockers (BBs) were the most frequently prescribed medications. Majority of (83.1%) the patients received combination therapy. The most frequent two and three drugs class combination were ACEI + BB and ACEIs + CCB + BB, respectively. Drug treatment was modified for 22.2% of patients and blood pressure (BP) was controlled in 26.2% of patients. Older age was associated with good BP control (AOR 2.58, CI 1.27–5.24), while treatment modification was associated with poor BP control (AOR 0.21, CI 0.07–0.65). The findings indicate that BP control was low and factors like middle age and treatment modification contributed to the low BP control. It is recommended that the physicians should be adherent to current guidelines regarding the selection of appropriate antihypertensive medications so as to achieve target BP goals.

Knowledge, adherence and control among patients with hypertension attending a peri-urban primary health care clinic, KwaZulu-Natal

Background

Despite hypertension being a common condition among patients attending primary health care (PHC) clinics, blood pressure (BP) control is often poor. Greater insight into patient-related factors that influence the control of hypertension will assist in the development of an intervention to address the issues identified.

Aim

The aim of the study was to assess patient-related variables associated with hypertension control among patients attending a peri-urban PHC clinic.

Setting

The setting for this study was a peri-urban PHC clinic in KwaZulu-Natal.

Method

This was an observational, descriptive and cross-sectional study with 348 patients selected over a 1-month period. A validated questionnaire was used to collect data on patients’ hypertension knowledge and self-reported adherence, and BP recordings from their medical record were recorded to ascertain control.

Results

Of the 348 participants, only 49% had good BP control and 44% (152/348) had concurrent diabetes mellitus. The majority of patients had moderate levels of knowledge on hypertension and exhibited moderate adherence. There was a significant relationship between knowledge and reported adherence, between reported adherence and control, but not between reported knowledge and control.

Conclusion

Despite over 90% of the study population having moderate knowledge, and 62% with moderate reported adherence, BP was well controlled in only less than 50% of the study population. These findings suggest a need to emphasise adherence and explore new ways of approaching adherence.

Factors associated with blood pressure control among patients attending the outpatient clinic of a South African district hospital

OBJECTIVE

To determine the prevalence and factors associated with blood pressure (BP) control.

METHODS

In a cross-sectional study involving 251 consecutively-sampled patients, a semi-structured questionnaire collected information on socio-demography, co-morbidities, hypertension treatments and BP control. Data analysis included descriptive statistics and logistic regression.

RESULTS

Most participants were: on treatment for >5 years (60.6%); on three or more drugs (93.6%); treated according to guidelines (77%); and reported not missing medications in the last week (86.5%). BP control was achieved in only 31.5% and 16.7% of participants at the current and last visits, respectively. In multivariate regression analysis, a history of myocardial infarction (odd ratio [OR] = 0.41; P = 0.04) and being divorced/widowed (OR = 3.1; P = 0.01) predicted poor BP control.

CONCLUSION

This study confirms the prevalent sub-optimal control of BP and suggests the need for further studies to examine the relationship between marital support, critical medical events and BP control.
