The Effect of Nurse Process on Bowel Cleansing

Colonoscopy is still the gold standard method for the diagnosis and treatment of colon cancers. Preparation for colonoscopy is a complex processa (eg. restricted diet three days before the procedure and to drink large volumes of drog ) involving many steps. It has been shown that the symptoms experienced by patients during colonoscopy preparation have an impact on the quality of the colonoscopy procedure. Adequate bowel preparation is essential for successful colonoscopy imaging and to detect and remove existing polyps. aim of this study was to examine the effect of the nursing process applied by using standard nursing terminologies on colonoscopy preparation of outpatients on bowel cleansing.

This study was designed as a prospective, single-blind, randomized controlled trial. This study tested the hypothesis that the nursing process using thestandard nursing terminologies NANDA-I, NIC and NOC for colonoscopy preparation has an effect on adequate bowel cleansing.

Nurses use standardized nursing language (SNL) to address complex relationships between presenting problems and individuals from a holistic perspective. The most widely used nursing diagnosis classification worldwide is NANDA-I, which includes nursing outcomes and interventions, respectively. In this study, after determining the nursing diagnosis specific to the colonoscopy procedure (NANDA-I), we evaluated which nursing outcomes (NOC) were appropriate for the patient's condition and then selected the nursing interventions (NIC) with the highest probability of achieving the desired outcome and implemented a nursing process. The study was conducted as a prospective, endoscopist-blinded, randomized controlled trial at a hospital-based outpatient endoscopy center. Eligible patients were randomized into two groups. Both groups received verbal and written instructions according to standard care, while the intervention group received a nursing process. After the interview, NANDA-I diagnoses were determined according to the needs of the individuals, and NOC scales appropriate to these diagnoses were selected and NOCs were first evaluated. According to the prepared nursing care plan, the nursing interventions selected in accordance with the diagnoses were reminded to the patients by phone and their compliance with the colonoscopy preparation instructions was monitored. When the patient came to the hospital for colonoscopy, face-to-face interviews were conducted, and final evaluations of NOC scales were performed. Primary outcomes included bowel preparation scores graded using the Boston Bowel Preparation Score (BBPS) and secondary outcomes included scores on NOCs selected according to the process of preparation for the colonoscopy procedure.
