Full description
Aim of the study To evaluate the effectiveness of Gum Chewing on Polyethylene Glycol (PEG) Related Intake Adherence, GI Side Effects and Bowel Preparation among Patients Undergoing Colonoscopy at ILBS, New Delhi.
Operational Definitions
Assess:
In this study, Assess refers to evaluating the effectiveness of Gum Chewing on Polyethylene Glycol (PEG) Related Intake Adherence, GI Side Effects and Bowel Preparation among Patients Undergoing Colonoscopy at ILBS, New Delhi.
Effectiveness:
In this study, effectiveness refers to degree to which gum chewing is successful in improving the intake adherence, GI side effects and bowel preparation from taking PEG solution among patients undergoing colonoscopy in experimental group as compared with the control group.
Chewing gum:
In this study, commercially available sugar free chewing gum was used, these were made with a delicious sweet mint flavour for a clean and fresh feeling and chewing gum with the PEG solution was taken as per the evidenced based protocol.
Ingredients: Sorbitol, Gum Base, Glycerol, Natural and Artificial Flavors; Less than 2% of: Hydrogenated Starch Hydrolysate, Aspartame, Mannitol, Acesulfame K, Soy Lecithin, Xylitol, Colors (Blue 1 Lake, Beta-Carotene), BHT (To Maintain Freshness).
GI Side Effects:
In this study, GI side effects refers to occurrence of gastro intestinal symptoms including abdominal discomfort, nausea, vomiting and retching secondary to the intake of PEG solution for bowel preparation in patients undergoing colonoscopy.
Abdominal discomfort:
In this study, abdominal discomfort refers to the sense of bowel movement and abdominal pain caused by intake of polyethylene glycol solution assessed by Numerical Rating Scale.
Nausea, Vomiting and Retching:
In this study, Nausea was defined as the desire to vomit without indulging in expulsive muscular movements. Vomiting was defined as the oral expulsion of gastrointestinal contents, while retching was the attempt to vomit without expelling any material. All these three parameters was assessed by using Rhodes index of nausea, vomiting and retching.
Intake Adherence:
In this study, it refers to the degree to which the patients undergoing colonoscopy follows the instructions related to PEG solution intake for bowel preparation. It was measured in terms of the total amount of PEG solution ingested, the total time taken for ingestion, extra fluid taken and total fluid taken before the colonoscopy.
Bowel Preparation:
In this study, bowel preparation refers to the extent to which the colon was cleared off the fecal matter following PEG solution ingestion in the patient undergoing colonoscopy. It was assessed by the colonoscopist using BBPS.
Polyethylene glycol solution:
In this study, PEG solution was given for bowel preparation for patients undergoing colonoscopy as prescribed by doctors. It was available in form of packet i.e., to be dissolved in 2 L of water. Patient was instructed to ingest whole solution within 2 hours as per the ingestion protocol.
Patient:
In this study, patient refers to the individual who was advised for colonoscopy for therapeutic or diagnostic purpose during the data collection period at OPDs of ILBS.
Colonoscopy:
In this study, colonoscopy refers to the elective procedure done to examine the colon for diagnostic and/or therapeutic purposes of various diseases like colorectal cancer, intestinal obstruction, GI bleeding etc.
Development and Description of Tools
Tools were prepared on an extensive review of books, journals, articles, Guide and Expert's opinion and investigators personal experience.
For the selection and preparation of tools, the following steps were taken:
Planning for required tools. An extensive review of tools used in various literatures was undertaken. Discussion with Guides, Peer group and Professionals. A formal observation in the concerned area of the study. Requirement of the tools according to objectives and the conceptual framework were sought. Opinion of 9 Experts was sought to determine the clarity, relevance, representativeness, comprehensiveness, ambiguity and simplicity of the tools.
Thus the most appropriate tools were used in the present study. These tools were majorly divided into six sections as follows:
Structured Questionnaires Section I: Subject Data Sheet which further consist of
Section A- Socio-Demographic Variables Section B- Clinical Variables Section II: Intake adherence Standardized Tools Section III: Numerical Rating Scale Section IV: The Rhodes Index of Nausea, Vomiting and Retching (INVR). Section V: Boston Bowel Preparation Scale. Structured Tools Section VI: Record Sheets Patient's Log Book
