A Study to Assess the Impact of Preoperative Education on Anxiety and Postoperative Outcomes in Patients Undergoing Major Abdominal Surgery

Surgical interventions, particularly major abdominal surgeries, are associated with significant physical and psychological stress. Among these, preoperative anxiety is one of the most common psychological responses experienced by patients. This anxiety, which may arise due to fear of the unknown, anesthesia, pain, possible complications, or even death, can adversely affect perioperative outcomes. Multiple studies have established that preoperative anxiety is linked to increased postoperative pain, delayed wound healing, prolonged hospital stay, higher analgesic requirements, and reduced patient satisfaction (Guo et al., 2012). According to Caumo et al. (2001), approximately 60%–80% of patients undergoing major surgery experience moderate to severe levels of preoperative anxiety. Moreover, anxiety-related sympathetic activation can lead to hemodynamic instability during and after surgery, compromising recovery. Preoperative education, which includes information about the surgical procedure, anesthesia, postoperative expectations, and recovery process, is considered an effective strategy to reduce preoperative anxiety. It empowers patients by enhancing their knowledge, correcting misconceptions, and fostering realistic expectations, thereby reducing fear and promoting cooperation. Evidence from various randomized controlled trials suggests that preoperative education significantly lowers anxiety levels, improves pain management, decreases postoperative complications, and shortens the length of hospital stay (Johns Hopkins Medicine, 2020; Devine, 1992). Yet, in many clinical settings, especially in resource-limited or busy hospital environments, structured preoperative education is often overlooked or inadequately provided.

Need of the study:

Given the high prevalence of preoperative anxiety and its negative impact on surgical outcomes, there is a crucial need to explore and implement non-pharmacological interventions that can improve patient care and safety. Major abdominal surgeries often require extensive recovery time, and anxiety can further complicate this process, leading to poor surgical outcomes and increased healthcare costs. In India, where the healthcare system is burdened with a high volume of surgical cases and often limited time for individualized patient education, standardized preoperative counseling is rarely practiced.

Maheshwari et al. (2016) studied preoperative anxiety in Indian surgical patients and found that 70% experienced moderate to severe anxiety prior to surgery. The anxiety was significantly associated with postoperative pain and delayed mobilization. The authors emphasized the importance of addressing psychological preparedness to improve surgical outcomes.

Johns Hopkins Medicine (2020) emphasized the use of multidisciplinary preoperative education clinics. Their internal data showed a 30% reduction in anxiety levels, 25% decrease in pain scores, and improved discharge outcomes.

Verma et al. (2017) conducted a cross-sectional study in a government hospital in India and found that only 20% of surgical patients received any form of structured preoperative education. Majority relied on verbal assurances, leading to inadequate preparation and increased anxiety. The authors recommended that structured protocols be integrated into nursing practice.

Chinnasamy et al. (2018) implemented a structured preoperative education module in a tertiary hospital in South India. Their findings showed significant improvements in patients’ knowledge, reduced anxiety levels, and early mobilization postoperatively

Furthermore, the World Health Organization (WHO) and the American Society of Anesthesiologists (ASA) emphasize the importance of addressing patients’ psychological needs as part of holistic perioperative care. A structured preoperative educational program not only benefits the patients psychologically but also enhances clinical efficiency, reduces medication dependency, and supports early mobilization post-surgery. Despite the high prevalence of preoperative anxiety among patients undergoing major abdominal surgery and its known negative impact on postoperative outcomes, structured preoperative education is not routinely provided in many clinical settings. There is a lack of consistent implementation of evidence-based, non-pharmacological interventions to reduce anxiety and improve surgical recovery. Therefore, this study seeks to assess the impact of structured preoperative education on preoperative anxiety and postoperative outcomes in patients undergoing major abdominal surgery.

OBJECTIVES:

The objectives of the study were to;

1. assess the preoperative anxiety levels among patients undergoing major abdominal surgery.
2. evaluate the effectiveness of structured preoperative education in reducing postoperative anxiety among patients undergoing major abdominal surgery.
3. assess the impact of structured preoperative education on postoperative outcomes such as pain level, mobilization, complications, and length of hospital stay between patients who received preoperative education and those who did not.
4. determine the association between preoperative anxiety levels and selected demographic variables among patients undergoing major abdominal surgery.
