| Summary: | Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder with a prevalence that has been increasing steadily and rapidly across the world, including the Caribbean region. It has negatively impacted individuals health and wellbeing, and in addition, it has increased the economic and social burden on the countries. T2DM management is an integral part of positive health outcomes, however, it has been poor in the Caribbean and is resulting in an alarming number of complications. The best way to reduce the negative outcomes associated with T2DM is to ensure that the disease is managed correctly. To do this, issues associated with poor T2DM management must be identified and disseminated to the public.
Aim
This thesis aims to highlight and raise awareness of the disparities impacting T2DM management in the Caribbean region to assist with future research, developmental plans and strategies. From the main aim two study objectives were developed. The first objective was to compare the content and quality of the Caribbean and international clinical guidelines for managing T2DM. The second objective was to summarise the barriers and facilitators to T2DM management in the Caribbean region.
Methods
To address the aim of this research a formative research approach was used, this is to ensure that the Caribbean government, healthcare professionals and researchers are provided with some of the necessary data needed to plan and develop interventions. This formative research included two separate studies and methods, one to address each aim. The first study appraised T2DM management guidelines including the Caribbean guideline which compared the content and quality of guidelines using the AGREE II tool. The second study was a systematic review which summarised the barriers and facilitators to T2DM management in the Caribbean region.
Results
From the appraisal, the Caribbean clinical guideline was found to contain similar levels of T2DM management topics compared to six guidelines (one international and five country-specific guidelines) and contained higher content levels than the remaining three guidelines (two international and one country-specific). Three country-specific guidelines (Canada, England and Wales and Scotland) met the criteria of high-quality and could be recommended for current use in clinical practice. Four were only eligible for use in practice with modifications (two international and two country-specific). However, the country-specific guideline from the Caribbean as well as two additional guidelines (one international and one country-specific) were of low-quality and therefore, they were not recommended for use in practice.
The systematic review included eight studies, all of which focused on the patients’ perspective. There were six synthesized findings which included barriers and facilitators of T2DM management. These include, From the participants perspective sociocultural norms, demands and pressures were found to impact self-management and general care of T2DM (moderate certainty evidence); From the participants perspective environmental context and resources were found to impact the management of T2DM (high certainty evidence); From a patients perspective support systems were influential on the general management of T2DM (high certainty evidence); From the participants perspective personal background and circumstances can encourage and limit good self-management and general management of T2DM (high certainty evidence); From the participants perspective emotional factors were found to influence patients’ actions towards management of T2DM (high certainty evidence); and from the participants perspective psychological factors were found to influence patients’ adherence to T2DM management (moderate certainty evidence).
Summary
With the aim of reducing the number of cases and deaths associated with T2DM, this research successfully addresses knowledge gaps by determining and presenting the quality of published clinical guidelines for T2DM management used by healthcare professionals. It also assesses the information being provided and summarizes the factors that hinder the promotion of good T2DM management in the Caribbean. The findings from these studies provide evidence that the Caribbean islands can use to make informed decisions on future interventions or research to assist in the fight against T2DM.
