Abstract

Objectives:

To characterize the lived experiences and unmet needs of nutritional education among colorectal cancer patients undergoing chemotherapy based on the Knowledge-Attitude-Practice model, thereby informing the development of evidence-based nutritional intervention programs.

Methods:

A descriptive qualitative study was conducted using purposive sampling. From January to March 2022, semi-structured interviews were performed with 17 colorectal cancer patients undergoing chemotherapy at five tertiary Grade A general hospitals in western China. All interviews were audio-recorded, transcribed verbatim, and thematically analyzed. Two researchers independently coded the interviews using NVivo 12, and directed content analysis was employed to inductively summarize and refine themes.

Results:

Five barriers to effective nutritional education were identified: (1) Lack of nutrition education knowledge, (2) Lack of evidence-based nutrition beliefs, (3) non-standardized nutritional practices, (4) Barriers to receiving nutrition education, and (5) Diversified needs for nutrition education.

Conclusions:

Colorectal cancer patients undergoing chemotherapy reported suboptimal nutritional education experiences and multifaceted needs, highlighting persistent challenges. Healthcare providers should comprehensively assess patients' educational experiences, deliver multimodal interventions addressing diverse needs, enhance education accessibility and acceptability, and strengthen nutritional awareness to mitigate malnutrition risks.

Practice Implication:

Our results provide insights for cancer patient nutrition educators to better help colorectal cancer chemotherapy patients, emphasizing the need to educate them about the knowledge, behaviors, beliefs, and more they have not received. This will enable colorectal cancer chemotherapy patients to receive better nutrition education, reduce their risk of malnutrition, and improve their recovery and quality of life.

Nursing Ethical Principles II

Nursing Ethical Principles II

Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

Chemotherapy-Induced Nausea and Vomiting: 5-HT₃ Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...
