Knowledge of hypertension and its management among hypertensive patients on chronic medicines at primary health care public sector facilities in South Africa; findings and implications

Sociocultural perceptions of physical activity and dietary habits for hypertension control: voices from adults in a rural sub-district of South Africa

BACKGROUND

Over half of adults from rural South Africa are hypertensive. Apart from pharmaceutical treatment, lifestyle changes such as increasing physical activity and reducing dietary salt have been strongly advocated for the control of hypertension. However, the control rates of hypertension for adults in rural South Africa are low. In this paper we explore whether this is due to the recommended lifestyle intervention not aligning with the individual's socio-cultural determinants of behaviour change.

AIM

To explore the social and cultural beliefs, perceptions and practices regarding physical activity and diet as a hypertension control intervention on hypertensive adults living in a rural sub-district in South Africa.

METHODS

Nine focus group discussions were conducted with hypertensive adults aged 40 years and above from Bushbuckridge sub-district in Mpumalanga Province of South Africa using a semi-structured interview guide. Each session began with introductions of the discussion theme followed by a short discussion on what the participants know about hypertension and the normal blood pressure readings. Physical activity and dietary habits were then introduced as the main subject of discussion. Probing questions were used to get more insight on a specific topic. A thematic analysis approach was used to generate codes, categories, and themes. A manual approach to data analysis was chosen and data obtained through transcripts were analysed inductively.

FINDINGS

Participants had a lack of knowledge about blood pressure normal values. Perceived causes of hypertension were alluded to psychosocial factors such as family and emotional-related issues. Physical activity practices were influenced by family and community members' attitudes and gender roles. Factors which influenced dietary practices mainly involved affordability and availability of food. To control their hypertension, participants recommend eating certain foods, emotional control, taking medication, exercising, praying, correct food preparation, and performing house chores.

CONCLUSION

Lifestyle interventions to control hypertension for adults in a rural South African setting using physical activity promotion and dietary control must consider the beliefs related to hypertension control of this population.

A Mixed Methods Protocol for Developing Strategies to Improve Access to Health Care Services for Refugees and Asylum Seekers in Gauteng Province, South Africa

Access to healthcare is a fundamental human right for all people, including refugees and asylum seekers. Despite the provision in the Refugee Act of South Africa, which allows refugees to enjoy the same access to health services as the citizens of the Republic, refugees still encounter challenges in accessing such services in Gauteng province. This protocol aims to develop strategies to improve access to health care services for refugees and asylum seekers in Gauteng province, South Africa. The study will be conducted in three phases. An exploratory sequential mixed methods design will be employed in phase 1 of the study; the initial study will be based on a qualitative approach followed by a quantitative approach. Phase 1 (a) of this study will employ a qualitative approach in Gauteng province among conveniently sampled health practitioners as well as purposively sampled refugees and asylum seekers. Interviews will be used to collect data that will be analyzed thematically. Phase 1 (b) will adopt a quantitative approach based on the findings from the initial qualitative study. The ethical principles of informed consent, anonymity, privacy, confidentiality, and avoidance of harm will be adhered to throughout the research process. Phase 1 (c) will be meta-inference and conceptualization. Phase 2 will focus on the development of strategies using strength, weakness, opportunities, and threats analysis and a build, overcome, explore, and minimize model to guide the process. In Phase 3, the Delphi technique will be used to validate the developed strategies. The conclusion and recommendations will be based on the findings of the study.

The of effect of partnership-based education on adherence to the treatment plans in open heart surgery

BACKGROUND

Adherence to the treatment plans is one of the most effective conducts to prevent and reduce postoperative side effects. Partnership-based education is one of the most efficient ways to shape health behaviors. The aim of the present study was to determine the effect of partnership-based education on adherence to the treatment plans in open heart surgery.

MATERIALS AND METHODS

This quasi-experimental study was conducted in 2019-2020 on the patients undergoing open heart surgery in Tehran (Capital of Iran). Sampling was done in one educational hospital. A total of 86 patients and their caregivers participated in the study. Sampling was done nonrandomly by tossing a coin, and patients were allocated into the odd week in the intervention group and the even week in the control group (n = 43 in each group), and data were collected before and after intervention using the Treatment Adherence Questionnaire concerning dietary, physical activity, and medication aspects. The educational intervention was carried out after the pretest analysis in five 20-45 min sessions (two individual and three group educations). Data were analyzed with Chi-square, independent t-test, and paired t-test using SPSS 19 at a significance level of P < 0.05.

RESULTS

Patients and caregivers in both groups did not have a significant difference in terms of demographic variables (P > 0. 05). In addition, there was no significant difference in the mean of dietary, physical activity, and medication plans before the intervention in both groups; however, after the intervention, the mean of the three aspects in the intervention group was significantly higher than that of control (P < 0.001).

CONCLUSION

Implementing partnership-based education with participation of patients and caregivers is influential in improving patients' adherence to the treatment plans and it is recommended as a clinical dynamic educational strategy.

Suboptimal control for patients with type 2 diabetes in the Central Chronic Medicine Dispensing programme in South Africa

BACKGROUND

In South Africa, the Central Chronic Medicine Dispensing and Distribution (CCMDD) programme allows stable patients with non-communicable diseases, including type 2 diabetes mellitus (T2DM), to collect their medication from a pick-up location near their home, thus avoiding long waiting times and travel expenses. The CCMDD programme aims at improving patient retention and adherence through better access to medicines, resulting in better health outcomes.

AIM

We assessed whether patients with T2DM enrolled in CCMDD achieved the recommended targets for glycaemic, blood pressure (BP) and lipid control.

SETTING

City of Tshwane, South Africa.

METHODS

We reviewed the records of 198 T2DM patients enrolled in CCMDD and assessed their control of haemoglobin A1c (HbA1c), BP and lipids.

RESULTS

Most of the records reviewed belonged to women (64.7%), African (89.9%), hypertensive (82.7%) and to patients exclusively on oral antidiabetic agents (98.5%). Patients were, on average, 57.7 (s.d. = 12.1) years old and had participated in the CCMDD programme for, on average, 2 years. The mean HbA1c was 8% (s.d. = 2). Glycaemic control was achieved by only 29.2% of patients, and 49% of patients had HbA1c between 7% and 9%. Ninety-three patients (66%) had achieved the total cholesterol target, 57.4% achieved BP targets and 6.9% had achieved the low-density lipoprotein cholesterol target.

CONCLUSION

A small group of patients achieved the targets for glycaemic, BP and lipid control. Despite improved accessibility to medication, the CCMDD is not synonymous of improved clinical outcomes. Future research should ascertain the factors associated with suboptimal control for these patients.

Prevalence of Hypertension and Its Associated Risk Factors in a Rural Black Population of Mthatha Town, South Africa

Background: The occurrence of hypertension has been increasing alarmingly in both low and middle-income countries. Despite acknowledging hypertension as the most common life-threatening risk factor for cardiovascular disease (CVD), a dearth of data is available on the prevalence, awareness, and determinants of hypertension in rural parts of South Africa. The principal aim of the current study is to determine the prevalence and associated risk factors of hypertension among a black rural African population from the Mtatha town of Eastern Cape Province. Methods: This was a cross-sectional study, and individuals over 18 years of age were randomly screened using a World Health Organization stepwise questionnaire. Sociodemographic information, anthropometric measurements, fasting blood glucose levels, and three independent blood pressure (BP) readings were measured. Blood pressure measurements were classified according to the American Heart Association guidelines. Univariate and multivariate analyses were performed to determine the significant predictors of hypertension. Results: Of the total participants (n = 556), 71% of individuals had BP scores in the hypertensive range. In univariate analysis, age, westernized diet, education, income, and diabetic status, as well as overweight/obese status were positively associated with the prevalence of hypertension. However, in a multivariate logistic regression analysis only, age, body mass index (BMI), diabetic status, and westernized diet were significantly associated with a higher risk of developing hypertension. Gender, age, and BMI were potential factors having a significant association with the treatment of hypertension. Individuals who did not consider the importance of medicine had higher chances of having their hypertension being untreated. Conclusions: Prevalence of hypertension was high among the black rural African population of Mthatha town. Gender, age, westernized diet, education level, income status, diabetic as well as overweight/obese status were the most significant predictors of hypertension.

Health behaviours and beliefs among Malawian adults taking antihypertensive medication and antiretroviral therapy: A qualitative study

In order to understand HIV-positive Malawian adults' experiences with hypertension management, we conducted qualitative interviews with 30 hypertensive adults who were also taking antiretroviral therapy. These interviews regarding hypertension management behaviours and beliefs were audio-recorded, transcribed, translated into English, and coded in Atlas.ti. Despite acknowledging the dangers of hypertension and the benefits of medication, many respondents missed their antihypertensive medication. Primary reasons included feeling healthy, health workers' advice to stop taking medicine when blood pressure normalised, side effects, and using herbs or non-prescription medicines to manage hypertension. Women highlighted difficulties with dietary modifications, and changes in their social relationships. Both men and women spoke about hypertension-related challenges with employment and household economics. These results suggest numerous challenges among adults managing hypertension and HIV in Malawi, and frequent suboptimal adherence to medication. We identified new key themes - the quality of adherence counselling for antihypertensive medication, the effects of hypertension on financial stability, and the role of social relationships in self-care - and encourage further investigation into these topics in low-income, high-burden countries.

Medicines Availability among Hypertensive Patients in Primary Health Care Facilities in a Rural Province in South Africa: Findings and Implications

Objective:

Controlling blood pressure (BP) in hypertensive patients is a challenge, with the lack of antihypertensive medicines negatively impacting on BP control. Consequently, we assessed the availability of prescribed antihypertensives among patients with chronic hypertension attending primary health care (PHC) facilities in a rural province of South Africa and explored any association between medicines availability, the number of prescribed antihypertensive medicines and BP control.

Methods:

Secondary data that included patients' demographics, BP, and data on medicines availability of the intervention group from a 3 months' operational study conducted in rural PHC facilities in South Africa were analyzed. The association between medicines availability, the number of antihypertensive medicines, and BP control was explored.

Findings:

Fifty-five African patients (89.1% females) with a mean age of 61.3 years were included. Two-thirds (67.2%) received all their medicines during their monthly visits, 25.5% received some, and for 7.3%, there was no record of whether medicines were dispensed or not. Patients with controlled BP (60.0%) were more likely to have been prescribed only one antihypertensive medicine compared to patients with uncontrolled BP (20.7%) (P = 0.017; odds ratio: 5.75; 95% confidence interval: 1.46, 22.61).

Conclusion:

It is concerning that one-third of patients went home without all of their antihypertensive medicines from PHC facilities in this Province of South Africa where there is evidence of use of herbal medicines and uncontrolled BP contributing to high morbidity and mortality from cardiovascular diseases. Additional studies are needed to fully explore the association between medicines availability, their use, and BP control among patients.

Fixed dose drug combinations - are they pharmacoeconomically sound? Findings and implications especially for lower- and middle-income countries

Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

Review of Ongoing Activities and Challenges to Improve the Care of Patients With Type 2 Diabetes Across Africa and the Implications for the Future

Background

There has been an appreciable increase in the number of people in Africa with metabolic syndrome and Type 2 diabetes (T2DM) in recent years as a result of a number of factors. Factors include lifestyle changes, urbanisation, and the growing consumption of processed foods coupled with increasing levels of obesity. Currently there are 19 million adults in Africa with diabetes, mainly T2DM (95%), estimated to grow to 47 million people by 2045 unless controlled. This has a considerable impact on morbidity, mortality and costs in the region. There are a number of issues to address to reduce the impact of T2DM including improving detection rates and current access to services alongside addressing issues of adherence to prescribed medicines. There are also high rates of co-morbidities with infectious diseases such as HIV and tuberculosis in patients in Africa with T2DM that require attention.

Objective

Document ongoing activities across Africa to improve the care of patients with T2DM especially around issues of identification, access, and adherence to changing lifestyles and prescribed medicines. In addition, discussing potential ways forward to improve the care of patients with T2DM based on ongoing activities and experiences including addressing key issues associated with co-morbidities with infectious diseases.

Our Approach

Contextualise the findings from a wide range of publications including internet based publications of national approaches coupled with input from senior level government, academic and other professionals from across Africa to provide future guidance.

Ongoing Activities

A number of African countries are actively instigating programmes to improve the care of patients with T2DM starting with improved diagnosis. This recognises the growing burden of non-communicable diseases across Africa, which has been neglected in the past. Planned activities include programmes to improve detection rates and address key issues with diet and lifestyle changes, alongside improving monitoring of care and activities to enhance adherence to prescribed medicines. In addition, addressing potential complexities involving diabetes patients with infectious disease co-morbidities. It is too early to fully assess the impact of such activities.

Conclusion

There are a number of ongoing activities across Africa to improve the management of patients with diabetes including co-morbidities. However, more needs to be done considering the high and growing burden of T2DM in Africa. Ongoing research will help further benefit resource allocation and subsequent care.

Pharmacotherapeutic interventions for bipolar disorder type II: addressing multiple symptoms and approaches with a particular emphasis on strategies in lower and middle-income countries

Introduction: Appropriately managing mental disorders is a growing priority across countries in view of the impact on morbidity and mortality. This includes patients with bipolar disorders (BD). Management of BD is a concern as this is a complex disease with often misdiagnosis, which is a major issue in lower and middle-income countries (LMICs) with typically a limited number of trained personnel and resources. This needs to be addressed.Areas covered: Medicines are the cornerstone of managing patients with Bipolar II across countries including LMICs. The choice of medicines, especially antipsychotics, is important in LMICs with high rates of diabetes and HIV. However, care is currently compromised in LMICs by issues such as the stigma, cultural beliefs, a limited number of trained professionals and high patient co-payments.Expert opinion: Encouragingly, some LMICs have introduced guidelines for patients with BD; however, this is very variable. Strategies for the future include addressing the lack of national guidelines for patients with BD, improving resources for mental disorders including personnel, improving medicine availability and patients' rights, and monitoring prescribing against agreed guidelines. A number of strategies have been identified to improve the treatment of patients with Bipolar II in LMICs, and will be followed up.

Factors hindering hypertension control: perspectives of front-line health professionals in rural Ghana

OBJECTIVE

Hypertension (HTN) control remains a major public health challenge in sub-Saharan Africa (SSA). Health professionals influence patient adherence and self-management practices for HTN particularly in rural and lower socio-economic communities in SSA. Contextual evidence on the reasons for the suboptimal control of HTN in clinical settings is crucial to improving health delivery practices for HTN and preventing HTN related-complications.

STUDY DESIGN

A cross-sectional qualitative study.

METHODS

Semistructured interviews were conducted among 40 purposively sampled front-line health professionals in seven health facilities in northern Ghana. Data were analysed using a thematic approach through pre-identified and evolving themes.

RESULTS

We identified three key themes underlying the poor HTN control. First, health professionals' barriers included communication difficulties, poor collaboration and referrals among health professionals and limited training on HTN and other non-communicable diseases (NCDs). Secondly, health system-related barriers included limited health personnel, drug shortages, inadequate facilities and equipment and challenges with National Health Insurance (NHIS). The third theme was patient-related barriers including non-adherence, use of traditional treatments, sociocultural factors and lack of appreciation.

CONCLUSION

A holistic public health approach, which builds upon health professionals' capacities, harnesses and integrates into existing health policy and systems structures and empowers and collaborates with communities could contribute to improving HTN control in rural settings. Health policymakers need to consider the sociocultural, economic and geographical characteristics in such settings, which influence health service delivery practices in designing and implementing HTN interventions. There is also a need for health policy to integrate NCD training and management of multiple and comorbid conditions into the training curriculum of health training institutions to build health professionals capacity to facilitate the uptake of evidence-based NCD interventions and manage the double burden of diseases.

Empowering Hypertensive Patients in South Africa to Improve Their Disease Management: A Pharmacist-Led Intervention

Objective:

Uncontrolled hypertension negatively impacts on mortality. This study aimed to evaluate the impact of a pharmacist-led patient counseling and education model to empower hypertensive patients on chronic medication.

Methods:

This was an operational research project with a quasi-experimental design including an intervention group (55 patients) and a control group (31 patients) of chronic hypertensive patients. The data were collected with interview-administered questionnaires, and were analyzed using SAS^® version 9.4. Pharmacist interventions included an educational diary on hypertension management and patient counseling.

Findings:

A 34.7% improvement was observed in patients’ understanding of what normal blood pressure (BP) is in the intervention group compared to the control group (P < 0.001), whereas a 9.1% improvement was also observed in the intervention group in their knowledge about the fact that systolic BP and diastolic BP are both important in controlling hypertension, with no change in the control group. After the intervention, 40.0% of patients in the intervention group versus 17.9% in the control group had adequate knowledge (≥75% correct answers) about hypertension and its management. Pharmacist interventions were well received by the majority of patients (>90%).

Conclusion:

A pharmacist-led patient counseling and education model can help improve patients’ hypertension knowledge and BP control. These should increasingly become routine, aiming to improve chronic disease management.

A Cost Analysis of Haemodialysis and Peritoneal Dialysis for the Management of End-Stage Renal Failure At an Academic Hospital in Pretoria, South Africa

BACKGROUND

Haemodialysis (HD) and peritoneal dialysis (PD) are commonly used treatments for the management of patients with end-stage renal disease (ESRD). The costs of managing these patients have grown in recent years with increasing rates of non-communicable diseases, which will adversely impact on national health budgets unless addressed. Currently, there is limited knowledge of the costs of ESRD within the public healthcare system in South Africa.

OBJECTIVE

The aim of this study was to examine the direct costs of HD and PD in South Africa from a healthcare provider's perspective.

METHODS

A prospective, observational study was undertaken at a leading public hospital in South Africa. A micro-costing approach was applied to estimate healthcare costs using 46 adult patients with ESRD who had been receiving HD and PD for at least 3 months.

RESULTS

The highest proportion of patients (35%) were aged 40-50 years. Patients aged 29-39 years were mostly on HD (28% vs. 21% on PD) while those aged 51-59 years mostly used PD (29% vs. 16% on HD). The average age of patients on HD and PD were 41 and 42 years, respectively. Fixed costs were the principal cost driver for HD ($16,231.45) while variable costs were the principal cost driver for PD (US$20,488.79). The annual cost of HD per patient (US$31,993.12) was higher than PD (US$25,282.00 per patient), even though the difference was not statistically significant (p = 0.816).

CONCLUSION

HD costs more than PD from the provider's perspective. These cost estimates may be useful for carrying out future cost-effectiveness and cost-utility analyses in South Africa.

Association Between Medication Literacy and Medication Adherence Among Patients With Hypertension

Background: Few studies have investigated the association between medication literacy and medication adherence as well as the influence of medication literacy on medication adherence in hypertensive patients. Thus, the goal of the present study was to determine the association between medication literacy and medication adherence in hypertensive patients. Methods: A cross-sectional survey was conducted between August 2016 and December 2016. Self-administered questionnaires were completed, including a self-developed and structured socio-demographic questionnaire; a self-developed, validated, and self-reported Medication Literacy Scale for Hypertensive Patients (C-MLSHP) used for medication literacy measurement; and the Chinese Version of the Morisky Medication Adherence Scale-8 (C-MMAS-8), an eight-item validated, self-report scale for adherence measurement with a total score range of 0-8. A cut-off of 6 was applied to differentiate adherence levels, including patients with an MMAS score <6 (low adherence), MMAS score = 8 (high adherence), and MMAS score ≥6 and <8 (moderate adherence). In this study, hypertensive patients' medication literacy levels and adherence to antihypertensive agents were identified. Pearson correlation analysis was carried out to identify the correlation between medication literacy and adherence. Binary logistic regression analysis was performed with medication adherence as the outcome variable in order to confirm factors associated with medication adherence. Results: A total of 420 hypertensive patients, including 198 women and 222 men with a mean age of 60.6 years (SD = 12.4), were recruited. The mean score of hypertensive patients on the medication literacy scale was 24.03 (SD = 5.13). The mean scores of the four dimensions of knowledge, attitude, skill, and behavior on the medication literacy scale of this study were 6.22 ± 2.22, 5.04 ± 1.16, 4.50 ± 2.21, and 8.27 ± 1.90, respectively. Regarding medication adherence, the mean score of the C-MMAS-8 in this study was 4.82 (SD = 2.11). A total of 63.6% of patients presented with low adherence, 29.5% presented with moderate adherence, and 7.6% presented with high adherence. The Pearson correlation results showed that medication literacy (r = 0.342, P < 0.01) as a whole variable and the three dimensions of knowledge (r = 0.284, P < 0.01), attitude (r = 0.405, P < 0.01), and behavior (r = 0.237, P < 0.01) were significantly associated with medication adherence. Binary logistic regression analysis indicated that annual income [OR 1.199 (95% CI: 1.011-1.421); P = 0.037] and two dimensions of attitude [OR 2.174 (95% CI: 1.748-2.706); P = 0.000] and behavior [OR 1.139 (95% CI: 1.002-1.294); P = 0.046] in medication literacy were found to be independent predictors of medication adherence. Individuals with better attitudes and behavior literacy in medication literacy were more likely to adhere to the use of antihypertensive agents. Those who had higher annual incomes were more likely to adhere to the use of antihypertensive agents. Conclusion: The levels of medication literacy and medication adherence of hypertensive patients are suboptimal and need to be improved in China. The level of medication literacy in patients with hypertension could affect their adherence to antihypertensive drugs. It was suggested that hypertensive patients' medication adherence could be improved and driven by increasing the medication literacy level, especially in the attitude and behavior domains. Pertinent strategies that are specific to several dimensions of medication literacy should be developed and implemented in order to promote full medication literacy among hypertensive patients, thus facilitating optimal adherence and blood pressure control.

Hypertension in a rural community in South Africa: what they know, what they think they know and what they recommend

BACKGROUND

Hypertension is one of the most important risk factors for cardiovascular disease and has a high prevalence in South Africa and other low- and middle-income countries. However, awareness of hypertension has been reported to be low. Health programmes can increase awareness of hypertension and its causes, but hinge on the knowledge and perception of the targeted community. Therefore, this study investigated knowledge on and perceptions about hypertension of community members in a rural area in Limpopo, South Africa with the aim to increase awareness of hypertension and cardiovascular disease in the local population.

METHODS

Using a mixed methods study approach, 451 participants of the Ndlovu Cohort Study, attending a follow-up visit between August 2017 and January 2018, completed a questionnaire on cardiovascular risk perception. A knowledge score was calculated for all participants. Sixty participants were invited to participate in six focus group discussions, of which 56 participated. Audio recordings were transcribed verbatim, transcripts coded, and thematic analysis of the data undertaken to obtain an understanding of knowledge and perception of hypertension in the community.

RESULTS

Most members of the community seemed to have intermediate (74.3%) or good (14.0%) knowledge of hypertension based on the knowledge score, and only 11.8% of the population had poor knowledge. The risk factors of hypertension seemed to be well known in the community. Poverty was identified as a major vulnerability in this community limiting choices for healthy lifestyles such as nutritious foods, recreational physical activity and accessing health care timely. Participants proposed community-based activities as an effective way to reach out to community members for prevention and management of hypertension.

CONCLUSION

This study highlights the need for improved health promotion efforts to increase knowledge of hypertension in rural communities, and to address poverty as a major obstacle to healthy life-style choices.

Knowledge regarding medicines management of type 2 diabetes amongst patients attending a Community Health Centre in South Africa

Objective

The prevalence of type 2 diabetes mellitus (T2DM) is growing in Sub-Saharan countries including South Africa. This is a concern given its appreciable impact on morbidity, mortality and costs with the recent introduction of universal health care in South Africa. The purpose of the study was to assess the knowledge of patients with T2DM attending a typical community health centre (CHC) regarding the management of their disease including risk factors and prevention to guide future initiatives. Typically, patients with T2DM in South Africa are managed in ambulatory care including CHCs.

Method

A quantitative, descriptive study in a CHC. The sample included 217 adults with T2DM who have visited a physician as well as the pharmacy. Face-to-face patient exit interviews were conducted using a structured questionnaire.

Key findings

Females predominated (65%), with the majority of patients &gt;60 years (38.2%) and more than half from the Indian racial category. Most patients did not know how their medication controls their diabetes (79.3%) or did not know any of the side effects (83.9%) from their medication. Less than half of the patients knew how to take their medication, and more than a third of patients indicated that they were not practicing any form of self-care.

Conclusion

The results indicate that these T2DM patients lacked sufficient knowledge regarding the management of their disease. Healthcare managers should consider instigating programmes to improve patients’ knowledge about the management of their disease as part of general initiatives within South Africa to improve the management of patients with chronic diseases in the public sector.

Prevalence of chronic kidney disease using estimated glomerular filtration rate among diabetes patients attending a tertiary clinic in Botswana

OBJECTIVES

Diabetes mellitus (DM) is one of the most common contributors of chronic kidney disease (CKD). The epidemiology of CKD, a concern among patients with DM, has not been studied in Botswana. Consequently, the objective of this study was to estimate its prevalence among these patients in Botswana to provide future guidance to both government personnel and physicians.

METHODS

Observational cross-sectional study in a leading clinic in Botswana. Demographic and clinical data were obtained from patients through interviews and from their notes using a standard questionnaire. The study was conducted from July to October 2015. The estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet for Renal Disease equation. CKD was defined as an eGFR < 60 ml/min/1.73 m². Multivariable logistic regression analyses were performed to assess the associations between CKD and potential factors.

RESULTS

The mean age and duration of DM among study participants were 54.67 years (range 21-92 years) and 5.0 years, respectively. Over half, i.e. 213/370 (57.6%) and 232/370 (62.7%), had an average blood pressure greater than 140/90 mmHg and poor glycemic control (HbA1c > 7%), respectively. 31/370 patients (8.4%) had CKD. However, only 18/370 (4.9%) had a diagnosis of CKD documented in their charts. Age, level of education, and duration of diabetes were independently associated with CKD.

CONCLUSION

The prevalence of CKD by estimated eGFR was low compared to most previous studies. However, half of patients with CKD are not documented resulting in the potential for prescription errors and drug toxicity. A substantial number of our patients had uncontrolled hypertension and poor glycemic control. Older age, low level of education and longer duration of DM were associated with CKD. There is a need to carry out prospective studies to determine the association and role of glycemic and blood pressure control in CKD causation among patients with DM in Botswana.

Evaluation of antihypertensive adherence and its determinants at primary healthcare facilities in rural South Africa

Aim: To evaluate adherence to antihypertensive treatment in rural South Africa and identify potential determinants given concerns with adherence and its impact in this priority disease area. Patients & methods: Face-to-face interviews with hypertensive patients and rating their adherence to treatment using defined categorized responses. Associations between adherence and patient characteristics assessed and sensitivity analyses performed. Results: 54.6% of patients were adherent to treatment. Controlled blood pressure (BP; odds ratios [OR] = 2.1; 95% CI: 1.1, 3.8; p = 0.019), comorbidity (OR = 2.0; 95% CI: 1.1, 3.6; p = 0.032) and smoking (OR = 0.3; 95% CI: 0.1, 0.8; p = 0.018) were associated with adherence. Conclusion: Adherence and BP control were suboptimal, only smoking was an independent risk factor for adherence. Adherent patients were twice as likely to have controlled BP, although results were sensitive to the definition of adherence. Initiatives are in place to improve adherence, which will be monitored.

Creating and evaluating an opportunity for medication reconciliation in the adult population of South Africa to improve patient care

OBJECTIVE

Adverse drug events (ADEs) are a major cause of morbidity and mortality, with more than 50% of ADEs being preventable. Adverse Drug Reactions (ADRs) are typically the result of an incomplete medication history, prescribing or dispensing error, as well as over- or under-use of prescribed pharmacotherapy. Medication reconciliation is the process of creating the most accurate list of medications a patient is taking and subsequently comparing the list against the different transitions of care. It is used to reduce medication discrepancies, and thereby ultimately decreasing ADEs. However, little is known about medicine reconciliation activities among public hospitals in South Africa.

METHODS

Prospective quantitative, descriptive design among Internal and Surgical wards in a leading public hospital in South Africa.

RESULTS

145 study participants were enrolled. Over 1300 (1329) medicines were reviewed of which there was a significant difference (p = 0.006) when comparing the medications that the patient was taking before or during hospitalisation. A total of 552 (41.53%) interventions were undertaken and the majority of patients had at least 3.96 medication discrepancies. The most common intervention upon admission was transcribing the home medication onto the hospital prescription (65.2%) followed by medication duplication (13.44%). During patient's hospital stay, interventions included patient counselling (32.5%) and stopping the previous treatment (37.5%).

CONCLUSION

To ensure continuity of patient care, medication reconciliation should be implemented throughout patients' hospital stay. This involves all key professionals in hospitals.

Ongoing Initiatives to Improve the Quality and Efficiency of Medicine Use within the Public Healthcare System in South Africa; A Preliminary Study

Introduction: South Africa has an appreciable burden of both communicable and non-communicable diseases as well as high maternal, neonatal, and child morbidity.
