Abstract

Please include objective, background, study method and anticipated results

English (max. 200 words)

Background:

The role of the dietician is currently very limited. In previous research has shown that only 35% of patients who underwent bariatric surgery had received an opinion of the dietitian [1 & 2]. From another study of the VIC (Volks Institute Curacao) showed that 28.3% of the adults from Curacao have obesity.[7].

The most effective treatment of morbid obesity is bariatric surgery [3].

Objective: to get insight in the importance of the dietician in the pre- and postoperative phase by bariatric surgery on Curacao.

Methods:

This protocol provides a qualitative and quantitative research to get insight of the current situation of bariatric surgery on Curaao, the percentage of morbid obese on Curacao, the role of the dietician in the pre and postoperative phase and the importance of the dietician in bariatric surgery. This will be done by conducting a literature research and experiment.

Anticipated results: This qualitative and quantitative research is relevant because of the neurologic consequences that bariatric surgery could give. When having the surgery people tend to forget to adjust their eating ways. Therefore it is easy to develop a deficiency of vitamins and minerals that will cause the physical problems. This study is to determine the importance of the role of the dietitian is in bariatric surgery on Curacao. [2]

This research will be performed to determine the importance of the dietician at bariatric surgery in the pre- and postoperative phase on Curacao

Research protocol

Type of the study The type of the research protocol is empirical science research. This was chosen because this study is focused on the relationship between a dietician and patients in the pre- and postoperative period by bariatric surgery. The protocol contains a quantity and quality research.

Qualitative research is based on evidence-based literature. Data from the literature will show which currently protocols are used for bariatric surgery on Curacao, what the requirements are to do bariatric surgery and what the role of the dietician is in the pre- and postoperative phase of bariatric surgery. This is examined by comparing scientific evidence Level 1: Research Level A1 or at least two independently conducted A2-level studies [4]

Quantitative research through evidence-based literature.Data from the literature will show the percentage of the morbid obesity on Curacao, and the quantity of bariatric surgery a year. This is achieved by working to evidence-based information that is compared. Level 1: Research Level A1 or at least two independently conducted A2-level studies [4]

PopulationThe experiment is performed on patients of the St. Elisabeth Hospital on Curacao. These patients all have morbid obesity or meet the requirements to be performing bariatric surgery (these requirements are outdated in the literature).

Sample size These patients are randomly divided into two groups. - Group 1: 50% of the patients who will undergo bariatric surgery in the Sint Elisabeth Hospital are supervised by a dietitian in the pre- and postoperative phase - Group 2: 50% of patients who will undergo bariatric surgery in the Sint Elisabeth Hospital are not supervised by a dietitian in the pre- and postoperative phase - All other factors remain the same (for example: counseling by a psychologist etc.)

This experiment is carried out to see the differences between the importance of a dietician at bariatric surgery in the pre- and postoperative phase. This experiment will last for period of 2 year after surgery.

Type of measurements In this study we performed different sorts of measurements:Weight, BMI, fat percentage, muscle percentage, kcal intake, biological age, visceral fat, deficiencies and comorbidity in the pre- and postoperative period.

Data analysisThe collected data of the measurements are analyzed by the statistical program SPSS using the t-test.

Discussion

Advantages of chosen strategy:

- Qualitative research gives a good detailed insight of the role and importance of the dietician in the bariatric surgery. - Quantitative research gives exact numbers on which is more reliable - The combination of quality and quantity protocol is reliable

Possible drawbacks of the chosen strategy - The literature is difficult to trace because all the health checks are older than 3 years , so the validity is not up to date - The number of patients for the experiment is only known as the data of bariatric surgery on Curacao obsolete in the literature
