RESUMO

Background: In Tanzania, where over a third of the society is impoverished, the burden of NCDs which account for about two-fifths of all disability-adjusted life years (DALYs) and one-third of premature deaths has doubled in the past two decades. However, notwithstanding a wider realization of the escalating burden of NCDs across Tanzania, the link between NCD awareness and lifestyle practices at the population level is not well characterized. We aimed to establish the gap between NCD knowledge and healthy behaviors. Methods: This multi-regional community-based cross-sectional study was conducted in 5 regions of Tanzania between September 2022 and June 2023. A 22-item standardized tool evaluating various NCD risk behaviors was used in knowledge assessment and a cut-off of ≥70% was used to denote good knowledge. Bivariate analyses were performed to compare knowledge of NCD risk factors across various NCD risk subgroups. All tests were two tailed, and the significance was set at p<0.05. Results: A total of 5121 individuals were consecutively enrolled. The mean age was 47.2 years and females comprised over three-fifths (60.8%) of the participants. With regard to behavioral NCD risks, physical inactivity, unhealthy diet, smoking and alcohol consumption were present in 79.0%, 70.2%, 2.1% and 17.6% of participants, respectively. Moreover, biological risk factors, ie, excess body weight, hypertension, and diabetes were present in 68.4%, 55.8% and 13.0% of participants, respectively. The mean knowledge score was 77.1% and 70.3% of participants demonstrated good knowledge of NCD risk factors. Except for smoking, individuals who showed awareness of various NCD risk factors were found to have significant rates of risky behaviors. Conclusion: Despite sufficient NCD risk knowledge, incongruent lifestyle practices persist, highlighting a crucial concern. This suggests that awareness of NCDs and their risks may influence motivation for change but may not necessarily result in lifestyle modification.

RESUMO

BACKGROUND: Point-of-care cardiac ultrasound (cardiac POCUS) has potential to become a useful tool for improving cardiovascular care in Tanzania. We conducted a pilot program to train clinicians at peripheral health centers to obtain and interpret focused cardiac POCUS examinations using a hand-held portable device. METHODS: Over a 5-day period, didactic and experiential methods were used to train clinicians to conduct a pre-specified scanning protocol and recognize key pathologies. Pre- and post-training knowledge and post-training image acquisition competency were assessed. In their usual clinical practices, trainees then scanned patients with cardiovascular signs/symptoms, recorded a pre-specified set of images for each scan, and documented their interpretation as to presence or absence of key pathologies on a case report form. A cardiologist subsequently reviewed all images, graded them for image quality, and then documented their interpretation of key pathologies in a blinded fashion; the cardiologist interpretation was considered the gold standard. RESULTS: 8 trainees (6 Clinical Officers, 1 Assistant Medical Officer, and 1 Medical Doctor) initiated and completed the training. Trainees subsequently performed a total of 429 cardiac POCUS examinations in their clinical practices over a 9 week period. Stratified by trainee, the median percent of images that were of sufficient quality to be interpretable was 76.7% (range 18.0-94.2%). For five of eight trainees, 75% or more of images were interpretable. For detection of pre-specified key pathologies, kappa statistics for agreement between trainee and cardiologist ranged from - 0.03 (no agreement) for detection of pericardial effusion to 0.42 (moderate agreement) for detection of tricuspid valve regurgitation. Mean kappa values across the key pathologies varied by trainee from 0 (no agreement) to 0.32 (fair agreement). CONCLUSIONS: The 5-day training program was sufficient to train most clinicians to obtain basic cardiac images but not to accurately interpret them. Proficiency in image interpretation may require a more intensive training program.
