Background: Health-related quality of life (HRQOL) is an important aspect of diabetes mellitus care. The objective of the study was to determine the HRQOL of diabetes mellitus (DM) patients in Botswana as little known in Africa. Materials and methods: A cross-sectional study of 380 randomly selected DM patients in a tertiary clinic in Gaborone, Botswana was conducted to obtain Data on HRQOL and structured questionnaire was used to collect information on sociodemographic and clinical characteristics. Multivariate logistic regression to determine sociodemographic and clinical characteristics associated. Results: Majority of patients were female with no formal education or primary level of education. Mean HbA1c was 7.97% (SD: 2.02) and most patients had poor glycemic control. The majority had both worse physical composite score (PCS-12) and mental composite score (MCS-12), with worse proportions of the two. Female gender, older age ≥ 65 years, and the presence of three or more documented diabetic complications were associated with significant worse PCS-12. Presence of two diabetic complications, three or more diabetic complications, and musculoskeletal disease were associated with significant MCS-12. Conclusions: Diabetic patients in Botswana have relatively poor HRQOL. The fact that most patients present late with complications calls for policy attention to diagnose diabetes mellitus early and prevent associated complications, ultimately improving health-related quality of life among diabetes mellitus patients

SummaryIntroduction:Heart failure is a common cause of hospitalisation and therefore contributes to in-hospital outcomes such as mortality. In this study we describe patient characteristics and outcomes of acute heart failure (AHF) in Botswana.Methods:Socio-demographic, clinical and laboratory data were collected from 193 consecutive patients admitted with AHF at Princess Marina Hospital in Gaborone between February 2014 and February 2015. The length of hospital stay and 30-, 90- and 180-day in-hospital mortality rates were assessed.Results:The mean age was 54 ± 17.1 years, and 53.9% of the patients were male. All patients were symptomatic (77.5% in NYHA functional class III or IV) and the majority (64.8%) presented with significant left ventricular dysfunction. The most common concomitant medical conditions were hypertension (54.9%), human immuno-deficiency virus (HIV) (33.9%), anaemia (23.3%) and prior diabetes mellitus (15.5%). Moderate to severe renal dysfunction was detected in 60 (31.1%) patients. Peripartum cardiomyopathy was one of the important causes of heart failure in female patients. The most commonly used treatment included furosemide (86%), beta-blockers (72.1%), angiotensin converting enzyme inhibitors (67.4%), spironolactone (59.9%), digoxin (22.1%), angiotensin receptor blockers (5.8%), nitrates (4.7%) and hydralazine (1.7%). The median length of stay was nine days, and the in-hospital mortality rate was 10.9%. Thirty-, 90- and 180-day case fatality rates were 14.7, 25.8 and 30.8%, respectively. Mortality at 180 days was significantly associated with increasing age, lower haemoglobin level, lower glomerular filtration rate, hyponatraemia, higher N-terminal pro-brain natriuretic peptide levels, and prolonged hospital stay.Conclusions:AHF is a major public health problem in Botswana, with high in-hospital and post-discharge mortality rates and prolonged hospital stays. Late and symptomatic presentation is common, and the most common aetiologies are preventable and/or treatable co-morbidities, including hypertension, diabetes mellitus, renal failure and HIV.

Warfarin treatment requires regular and proper monitoring to avoid overanticoagulation and at the same time to prevent thromboembolic complications. This study assessed the quality of warfarin anticoagulation at Princess Marina Hospital in Botswana. This cross-sectional study consecutively enrolled patients who were on warfarin for at least 3 months in the outpatient medical clinic. The level of anticoagulation was determined by the time in therapeutic range (TTR) using the Rosendaal method that calculates the percentage of days when the international normalized ratio is in the therapeutic range (2.0-3.0). Poor anticoagulation control was defined as an estimated TTR <65%. We performed univariate and multivariate logistic regression to assess predictors of poor anticoagulation control. Of total, 410 (68.8% women) patients whose median age was 46 (interquartile range [IQR], 35-58) years were enrolled. Indications for warfarin included mechanical heart valves, 185 (45.1%); deep vein thrombosis, 114 (26.8%); and atrial fibrillation, 68 (17.8%). Of the 2004 tests (an average of 4.9 tests per patient) assessed, only 20% of the tests were within the therapeutic range. The median TTR was 30.8% (IQR, 15.2-52.7). Most (85.1%) patients had poor anticoagulation control. Cigarette smoking and pulmonary hypertension perfectly predicted poor anticoagulation. Hypertension was a predictor of poor anticoagulation control (adjusted odds ratio = 2.24; 95% confidence interval: 1.02-4.94). The quality of anticoagulant therapy with warfarin in Botswana patients is poor. The evidence calls for efforts to improve the level of anticoagulation control among patients on warfarin in Botswana.

Background and aims: Glycemic control among patients with diabetes mellitus is associated with a marked reduction of both macrovascular and microvascular complications; however, glycemic control remains an elusive goal worldwide. The aim of this study was to determine factors associated with glycemic control among patients attending a tertiary clinic in Botswana as limited information to date. Methods: Cross-sectional study in a tertiary clinic in Gaborone, Botswana. Patients were recruited between 21 st July 2015 and 21 st September 2015. The majority of the randomly recruited patients (368/380-96.8%) had documentation of glycemic control (HbA1c) within three months of study recruitment and were subsequently included in the analysis. Glycemic control was categorized as desirable, suboptimal and poor if HbA1c was < 7%, 7-9% and > 9% respectively. Data was analyzed using SPSS for descriptive statistics including both bivariate and multinomial logistic regression. Ap-value < 0.05 was considered statistically significant. Results: The analyzed study population consisted of 258/368 (70.1%) females with a mean age (SD) of 56.7± 13.6 years. Means (SDs) for diabetes duration and glycated haemoglobin were 7.2± 7.1 years and 7.97± 2.02% respectively. Of the 368 patients, 136 (36.95%) and 132/368 (35.86%) had desirableand suboptimal glycemic control respectively. Older age, attending the clinic for more or equal to 3 years and not being on insulin were associated with both desirable and suboptimal glycemic control whereas duration of diabetes between 5-10 years was associated with poor glycemic control. Conclusions: The majority of patients had poor glycemic control. Older age and not being on insulin were associated with better glycemic control. The fact that patients on insulin had poor glycemic control calls for more research to determine timing of insulin initiations and dosing schedule factors as these will help toimprove overall glycaemic control in Botswana and elsewhere.
