Stakeholder's perspectives on acceptable interventions for promoting hypertension medication adherence in Namibia: nominal group technique

A reflection on the use of virtual nominal group technique in health policy and research priority consensus studies

BACKGROUND

Nominal group technique (NGT) is widely used in healthcare research to facilitate decision-making and consensus-building. Traditional NGT requires face-to-face interaction and its limitations include potential biases, logistical challenges and high costs. The COVID-19 pandemic necessitated a shift to virtual methods, which led to the development of virtual nominal group technique (vNGT). Aim To reflect on the use of vNGT, particularly in the context of Ghader et al (2023 ), to understand its effectiveness in overcoming the limitations of traditional NGT and on its applicability in pandemic-affected scenarios.

METHOD

This paper reviews and discusses literature on the use and effectiveness of NGT compared to other consensus-building methods and examines the emergence of vNGT in overcoming the limitations of traditional NGT. The authors also reflect on their use of vNGT in a study to identify cardiovascular research priorities in the UAE and provide details of its implementation.

DISCUSSION

vNGT bridges the gap between the localised nature of traditional NGT and the global reach of the Delphi technique. It allows for the inclusion of diverse participants, saves costs and offers time-efficiency. The study demonstrated vNGT's adaptability, with participants engaging in idea generation, discussion and prioritisation using online tools. However, challenges persist with vNGT, including reduced accessibility for certain demographics, timing issues across time zones and technical difficulties.

CONCLUSION

vNGT successfully integrates the interactive, consensus-building aspects of NGT with the broad reach of Delphi. It can be valuable in research and decision-making, especially in an era of increased remote collaboration.

IMPLICATIONS FOR PRACTICE

vNGT can significantly impact healthcare research and policy formulation by enabling more inclusive, cost-effective and timely consensus-building processes. However, considerations for accessibility and technical support are crucial for its wider adoption and effectiveness.

Association of educational attainment with hypertension and type-2 diabetes: A Mendelian randomization study

BACKGROUNDDue to the long time interval between exposure and outcome, it is difficult to infer the causal relationship between educational attainment (EA) and common chronic diseases. Therefore, we utilized Mendelian randomization (MR) to predict the causal relationships of EA with hypertension and type-2 diabetes (T2DM). METHODSA two-sample MR analysis was conducted using genome-wide association studies (GWASs) combined with inferential measurements. A GWAS meta-analysis including 1,131,881 European individuals was used to identify instruments for EA. Hypertension and T2DM data were obtained from a Finnish database. MR analyses were performed using inverse-variance weighted meta-analysis (IVW), weighted median regression, MR‒Egger regression, simple mode regression, weighted mode regression and the MR-Pleiotropy RESidual Sum and Outlier test. Sensitivity analyses were further performed using the leave-one-out method to test the robustness of our findings. RESULTSUsing the MR approach, our results showed that EA was significantly associated with a reduced risk of hypertension (OR = 0.63; P = 2.94 × 10-47; [95% CI: 0.59, 0.67]) and type-2 diabetes (OR = 0.59; P = 1.25 × 10-16; [95% CI: 0.52, 0.67]). CONCLUSIONSThis study showed that EA is causally linked to the risk of chronic diseases, including high blood pressure and T2DM.

Improving Hypertension Control in Vulnerable Populations Around the World

PURPOSE OF REVIEW

This review aims to describe recent literature, guidelines, and approaches to reveal and reduce hypertension burden in disadvantaged populations. Hypertension is a major global health issue and the most potent risk factor for cardiovascular disease, morbidity, and mortality. It disproportionally affects vulnerable populations, including low-, middle-, and high-income countries. Specifically, the burden of hypertension is higher in US Black adults, and addressing social determinants of health is crucial for reducing disparities among vulnerable populations worldwide.

RECENT FINDINGS

Multifactorial approaches, including lifestyle modifications and combination drug therapy, are essential in managing hypertension. Community-based interventions, team-based care, and telehealth strategies can also improve hypertension control. Additionally, renal nerve denervation is a potential treatment for resistant hypertension. Overall, to reduce the global hypertension burden among vulnerable populations, emphasis should be placed on equitable healthcare access and application of evidence-based medicine.
