Advance knowledge of Physician about Total Parenteral Nutrition in Saudi Arabia

Objectives: To explore the physician’s advanced knowledge about Total Parenteral Nutrition in Saudi Arabia. Materials and Methods: It analyzes a cross-sectional survey that discussed the physician’s basic knowledge of some items for Total Parenteral Nutrition services (TPNs) in Saudi Arabian. The survey consisted of respondents’ demographic information about Physician knowledge of Total Parenteral Nutrition services (TPNs) calculations. Besides, the physician’s understanding of Total Parenteral Nutrition services (TPNs) adjusts based on diseases, Physician knowledge of Total Parenteral Nutrition services (TPNs) components for various populations. The 5-point Likert response scale system was used with closed-ended questions. The survey was validated through the revision of expert reviewers and pilot testing. Besides, various tests of the reliability of McDonald’s ω, Cronbach alpha, Gutmann’s λ2, and Gutmann’s λ6 were done with the study. Furthermore, the data analysis of the Pharmacist practice of Cardiopulmonary Resuscitation (CPR) medications is done through the survey monkey system. Besides, the Statistical Package of Social Sciences (SPSS), Jeffery’s Amazing Statistics Program (JASP), and Microsoft Excel sheet version 16. Results: A total number of 409 physicians responded to the questionnaire. Of them, almost onehalf responded from the Northern region (186 (45.48%)), and one Quarter responded from the central area (106 (25.92%)), with statistically significant differences between the provinces (p=0.000). Females responded more than males (268 (65.53%)) versus 141 (34.47%)), with statistically significant differences between all levels (p=0.001). Most of the responders were in the age group of 36-45 years (198 (48.41%)) and 46-55 years (109 (26.65%)), with statistically significant differences between all age groups (p=0.000). Almost one-half of responders, 176 (43.03%), worked at an organization that had Parenteral Nutrition services (TPNs) services, with only 86 (21.03%) had been ever requested any Parenteral Nutrition services (TPNs) with statistically significant differences between all answers (p=0.000). The average score of knowledge calculation of Total Parenteral Nutrition services components was (3.41). The element “Total daily requirement of the protein” obtained the highest score (3.81). The aspect “Total daily requirement of the electrolytes” was (3.77). The average score of knowledge the Total Parental Nutrition services (TPNs) adjust with various diseases was (3.70). The element “Hepatic Failure” obtained the highest score (4.30). The aspect “Renal failure” was (4.22). Conclusion: The advanced knowledge of physicians about parenteral nutrition calculations or adjusting parenteral nutrition based on the current disease was inadequate. Therefore, targeting undergraduates and postgraduate education and training is highly in the medical care.
