The Effectiveness of Patient Education on Laparoscopic Surgery Postoperative Outcomes to Determine Whether Direct Coaching Is the Best Approach: Systematic Review of Randomized Controlled Trials

Background As of 2022, patient adherence to postoperative guidelines can reduce the risk of complications by up to 52.4% following laparoscopic abdominal surgery. With the availability of various preoperative education interventions (POEIs), understanding which POEI results in improvement in patient outcomes across the procedures is imperative. Objective This study aims to determine which POEI could be the most effective on patient outcomes by systematically reviewing all the POEIs reported in the literature. Methods In total, 4753 articles investigating various POEIs (eg, videos, presentations, mobile apps, and one-on-one education or coaching) were collected from the PubMed, Embase, and Scopus databases. Inclusion criteria were adult patients undergoing abdominal laparoscopic surgery, randomized controlled trials, and studies that provided postoperative outcomes. Exclusion criteria included studies not published in English and with no outcomes reported. Title and abstract and full-text articles with POEI randomized controlled studies were screened based on the above criteria through a blinded, dual review using Covidence (Veritas Health Innovation). Study quality was assessed through the Cochrane Risk of Bias tool. The included articles were analyzed for educational content, intervention timing, intervention type, and postoperative outcomes appropriate for a particular surgery. Results Only 17 studies matched our criteria, with 1831 patients undergoing laparoscopic cholecystectomy, bariatric surgery (gastric bypass and gastric sleeve), and colectomy. In total, 15 studies reported a statistically significant improvement in at least 1 patient postoperative outcome. None of these studies were found to have an overall high risk of bias according to Cochrane standards. In total, 41% (7/17) of the included studies using direct individual education improved outcomes in almost all surgery types, while educational videos had the greatest statistically significant impact for anxiety, nausea, and pain postoperatively (P<.01). Direct group education demonstrated significant improvement in weight, BMI, exercise, and depressive symptoms in 33% (2/6) of the laparoscopic gastric bypass studies. Conclusions Direct education (individual or group based) positively impacts postoperative laparoscopic surgery outcomes.

Background
Adherence to postoperative guidelines can impact the risk of complications by up to 52.4% after laparoscopic surgery, as shown by a 2022 prospective study [1].The enhanced recovery after surgery (ERAS) protocol is a systematic approach to minimize postoperative pain, complications, and duration of hospital stay in patients undergoing surgical procedures [2][3][4].The protocol, established by the ERAS Society, a not-for-profit multiprofessional multidisciplinary medical-academic society, aims to determine the optimal approach for delivering care to patients undergoing surgical procedures, with the goal of facilitating quicker postoperative recovery [4].The ERAS protocol consists of patient education, preemptive analgesia, and other practical procedures to improve patient outcomes [4,5].The ERAS protocol continues to be implemented in a wide range of surgical fields and has been shown to significantly decrease patient complications from 35.7% to 16.4% in a prospective cohort study in 2016 [6].
As the ERAS protocol demonstrates, patient compliance after laparoscopic abdominal surgery is essential to reducing postoperative complications [7].Nonadherence to the recommendations set by the surgical team, such as medication consumption or general lifestyle suggestions, can have a significant impact on postoperative recovery and patient complications [1,8].For instance, studies have documented that poor compliance in patients undergoing gastric banding surgeries results in poorer outcomes, including reduced weight loss postoperatively [9].Educating patients on their surgical procedure, potential postoperative consequences, and preventive steps to minimize complications has improved patient compliance and reduced hospital stays following laparoscopic surgery [5,10].These preemptive measures may play a profound role in mitigating the psychological burden of pain, anxiety, and fear during recovery [11].

Objectives
As the laparoscopic approach in surgical procedures is considered to be newer, the research following its patient education for postoperative care is limited [12].To adapt to these novel approaches, modernized educational formats that have been shown to improve surgical patient outcomes include verbal, written, multimedia, mobile apps, and one-on-one or group counseling [11,13,14].As intervention types continue to be explored, there is no gold standard preoperative education intervention (POEI) that has shown consistent improvement in patient outcomes across the procedures.The aim of this study is to systematically review the literature on POEIs to ascertain which POEI is more effective in improving outcomes in patients undergoing laparoscopic abdominal surgery.

Methods
Our review adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and EQUATOR (Enhancing the Quality and Transparency of Health Research) guidelines This protocol is registered in the PROSPERO database (CRD42023438698) [15].

Search Strategy
A systematic search was performed using 3 databases: PubMed, Embase, and Scopus.The search strategy was developed through an iterative process, using the methodology recommended by the Study Center of the German Society of Surgery, and included key terms related to laparoscopic abdominal surgeries and patient education [16].The full search algorithm was used to identify potential articles in all 3 databases (Multimedia Appendix 1).

Article Selection
A total of 4753 articles investigating POEI were collected from the 3 databases after the removal of duplicates.Inclusion criteria were inclusion of a patient education intervention, adult patients undergoing abdominal laparoscopic surgery, randomized controlled trials (RCTs), and articles including postoperative outcomes (Figure 1).Exclusion criteria were articles not published in English, no patient education intervention included, nonabdominal laparoscopic procedures, pediatric patients, and articles without outcomes reported.Eligibility criteria are described using the population, intervention, comparator, outcomes, timing, and setting framework (Table 1).Title and abstract and full-text articles were screened using the inclusion and exclusion criteria via a blinded, dual review with 2 independent reviewers using Covidence (Veritas Health Innovation).If the decision was not unanimous, discrepancies were resolved after further review until a consensus was reached to determine final article inclusion or exclusion.

Data Extraction and Analysis and Study Quality
Study quality was assessed through the Cochrane Risk of Bias tool as all included studies were RCTs [17].Each domain assessed (ie, sequence generation, allocation concealment, blinding of participants and personnel, blinding of outcome assessment, incomplete outcome data, selective outcome reporting, and other sources of bias) were evaluated as "high," "low," or "unclear" risk of bias.An abstraction form was developed through an iterative process to standardize the data extraction process (Multimedia Appendix 1).Data extraction was performed via a blinded, dual review with 2 independent reviewers on Covidence, with any discrepancies resolved after further review.Study variables analyzed in this systematic review included educational content, intervention timing and duration, intervention type, surgery type, and postoperative outcomes related to a particular surgery.POEIs included educational videos, multimedia presentations, mobile apps, direct individual education, and direct group education.All extracted data were compiled for analysis using Google Sheets (Google Drive; Google, LLC).were connected to the patient for monitoring and the method of general anesthesia were shown to the patient.After anesthesia, the recovery room and dressings of the operation site were displayed to the patient.Subsequently, the anatomy of the gall-bladder and its function, as well as the gallbladder surgery by laparoscopy, were demonstrated.Moreover, the patient observed the advantages of the laparoscopy method compared with open surgery."

Literature Selection
• Animation 2 was used after surgery to manage pain.
• "A 40-year-old man was seated in a semisitting position, and the narrator states that this condition made it easier to breathe and reduce the pressure inside the abdomen, thereby reducing the pain.Deep breathing and effective coughing were displayed to the patient step by step, and an emphasis was put on the importance of causing faster CO2 (carbon dioxide) gas release from the abdominal cavity and secretions.In addition, the method of fixing the surgical incision with the help of a hand or a small pillow, which helps to reduce pain during coughing, deep breathing, and movement in bed, was demonstrated to the patient.Thereafter, movement in bed was shown to prevent blood clots and encourage faster expulsion of gas from the abdominal cavity.These movements included exercising the sole of the feet, ankles, and thighs.Finally, the patient was shown how to get out of bed step by step."

Surgery type Study
There was a statistically significant improvement in perceived information; however, no statistically significant improvement was found in the Knowledge and Skills Acquisition for anxiety.
• Content • Chapters with disease features, therapeutic alternatives, and the hospital stay, including a description of the operation itself.Certain pages are mandatory for the procurement of informed consent.

•
The chapters focus on the following: • Why does the operation need to be performed?
The risks of gallstones are presented.

•
Preoperative examinations are described in detail.Complex examinations are presented with videos of each procedure.

•
The chapter explaining that the operative procedure is divided into different sections.
The cholecystectomy is clarified using an animated graphic of the operation with a parallel description of the procedure by the surgeon.For interested patients, video from an actual operation is also available.
The first stage included providing information about cholelithiasis, including its causes, preoperative preparation, exercises, surgery, complications, wound care, nutrition, and medicines.Then, a video of laparoscopic cholecystectomy was played on a notebook.Finally, a leaflet about laparoscopic cholecystectomy was shown.In the second stage, knowledge about transfer to the operating room, its physical ambience and waiting room, surgical instruments, and explanations about anesthesia and surgical team were ensured.Information concerning what was expected of the patient before and during general anesthesia and how to join, recovery period, and how the patient is transferred were told.Besides, operating room pictures and surgical instruments were shown via the notebook.In the third stage, photographs and leaflets were used to train patients regarding postoperative care, both in the clinic and at home, such as how to mobilize and change dressing.In the fourth stage, any questions on different issues about laparoscopic cholecystectomy that were not mentioned by the researchers in patient's education were answered.Afterward, the patients were provided with a leaflet prepared by the researcher to reinforce what they had learned.

Surgery type Study
There was a statistically significant decrease in the VAS-pain and VAS-nausea scores of the intervention group at postoperative hours 0, 2, 4, 6, and 8.In addition, the 24-hour VAS-pain score of the intervention group was significantly lower than that of the control group.The VAS-vomiting scores of the control group were higher than those of the intervention group at postoperative hours 6 and 8.Moreover, a significant difference was noted between the intervention and control groups in terms of changes in the VAS-pain, nausea, and vomiting scores over time.Before the intervention, there was no significant difference between the groups in terms of the STAI c -I scores; however, a statistically significant difference was determined before surgery and at the postoperative hour 24.There was also a significant difference between the groups in terms of the changes in the STAI-I scores over time.No significant difference was observed between the 2 groups in relation to the STAI-II scores obtained before the intervention, before surgery, and at postoperative hour 24.When the patient learning needs subscale scores were compared before education, there was a significant difference between the 2 groups in terms of activities of living, community and followup, feelings related to condition, and enhancing quality of life.
Statistically significant reduction was observed in anxiety in ERAS d group compared to control on the day before surgery and 6 hours postoperatively.In addition, there was a statistically significant reduction in hunger, thirst, fatigue, and overall perioperative experience.[22] There was a statistically significant decrease in the first, second, and third month BMI (kg/m 2 ) mean scores of the experimental group; no statistically significant difference was found between Self-Care Mean Agency scores and mean scores of the Body Image Scale.
• Content • "The app includes care, nutrition, and exercise training for patients undergoing bariatric surgery, starting from the preoperative period, and covering the first 3 months after surgery, as well as a food and an exercise diary, and weight tracking interfaces that will help patients develop healthy lifestyle behaviors while adapting to their new lives.In addition to these, there is a live consultation where patients can communicate with researchers and interfaces with questionnaires and answers to frequently asked questions by patients."

Surgery type Study
At preoperative and 6 months postoperatively, there were no significant differences between intervention and control groups.However, at 12 months, both groups lost significant weight, with the intervention group losing significantly greater weight and significantly greater BMI reduction.Walking mean time, intensity of exercise, and involvement in physical activity was also significantly increased compared to control group at 12 months.No significant difference was found in daily energy intake and number of meals between groups.
• Content • "The first session of the education intervention addressed the daily meal planning guide and the maintenance diet.It provided recommendations on identifying and avoiding unhealthful foods, tips to promote proper nutrition by controlling portion size, new routine eating habits, and using an exchange list for weight management.This session was based on the Dietary Guidelines for Americans due to their reliable science-based advice on promoting health and lowering risk for chronic diseases via diet and physical activity.Daily energy intake was limited to 1,000-1,400 kcal and the minimum daily protein intake was 60-70 g with the goal of preserving lean tissue and prevent nutritional deficiencies.Additionally, the session also emphasized characteristics of typical Hispanic diets and the dietary changes that come with acculturation.The session also emphasized traits of typical Hispanic diets and the dietary changes that come with acculturation.There was a statistically significant difference between the mean postoperative fifthday pain scores of the experimental and control groups.There was a statistically significant difference between the mean postoperative fifthday scores of the experimental and control groups.
• Content • "The 9-minute animation education, which was prepared for postoperative sleeve gastrectomy patients, was written and directed by the researchers.The nurse explained how the deep breathing exercise was done using the benefits of respiration exercises (2 minutes) in the first part and the diaphragmatic breathing exercises and incentive spirometry (4 minutes) in the second part.In the third part, the researcher first showed how to do the exercises and then repeated the exercises with the patients (3 minutes)."• Content • "For the standardization of patient education, an education booklet was prepared in consultation with academic nursing experts.The content included information on the operating room environment and surgical team, anesthesia process, postoperative care, and surgical process.The patient education was not given by the researchers in order to prevent research bias.To avoid any differences between the educators, all education was carried out by one voluntary service nurse and one operating room nurse.About two hours of education was given to the nurses to ensure they adopted a similar approach in patient education and to prevent bias caused by individual factors."A total of 1831 patients undergoing laparoscopic cholecystectomy, bariatric surgery (ie, gastric bypass and gastric sleeve), and colectomy were included.There were a wide range of patient postoperative outcomes reported in the included studies, including nausea, complication rate, and weight loss (Table 3).These patient outcomes were categorized into patient discomfort, surgical outcomes, and quality of life.No included studies had an overall high risk of bias (Table 4).The PRISMA flowchart illustrates the process of selecting articles in Figure 1 [35].

Patient Discomfort
The Patient Discomfort category consisted of nausea, pain, and anxiety as patient's postoperative outcomes.
Nausea was significantly (P<.05) reduced in 2 intervention types.Following laparoscopic cholecystectomy, 43 patients who received direct individual education demonstrated a decrease in postoperative nausea, as measured by the Mini Nutritional Assessment test and the simplified Apfel scale [21].
Educational videos preoperatively also proved to decrease patients' reporting of nausea [30,32].The educational video study by Toğaç and Yılmaz [32] was conducted on 124 patients, and the results were obtained using the Visual Analog Scale (VAS).The study by Stergiopoulou et al [30] was conducted on 60 patients, and the results were obtained using the Numerical Rating Scale ranging from 0 to 10.These 2 studies demonstrated statistical significance.
Pain was reduced postoperatively following 2 main interventions: direct individual education [21] and educational videos [18,30,32,34].Direct individual education and educational videos displayed a statistically significant reduction in pain (P<.05 and P<.01, respectively).The educational video study conducted by Abbasnia et al [18] included 145 patients, and results were obtained with the VAS and McGill Pain Questionnaire.Yayla and Menevşe [34] analyzed 66 patients via the VAS.
Anxiety was shown to be statistically decreased (P<.01) in POEIs that incorporated both educational videos [18,30] and presentations [33].The educational video intervention used by Abbasnia et al [18] included 145 patients and collected data via the State-Trait Anxiety Inventory.While Stergiopoulou et al [30] collected data via the Amsterdam Preoperative Anxiety Scale and Information, Udayasankar et al [33] focused on 50 patients and reported a reduction in preoperative anxiety (P=.003) and postoperative anxiety after 6 hours (P=.001).

Surgical Outcomes
Surgical outcomes category consisted of percentage of unexpected hospitalizations, complication rate, intensive care unit (ICU) admission, first exhaust time, and first defecation time.These varying patient outcomes provide insight into the patient's condition after surgery.Percentage of unexpected hospitalizations postoperatively was not significantly reduced when direct individual education intervention type was introduced [31].Complication rate, ICU admission, first exhaust time, and first defecation time were all reduced postoperatively when patients were debriefed via individual education or coaching intervention [25,27].Molenaar et al [27] included 251 patients and measured their results via Comprehensive Complication Index (P=.02).Li et al [25] obtained their results via observation indicators.

Quality of Life
Factors that affect quality of life were also considered to have a detrimental effect on a patient's long-term well-being.This category consisted of patient outcome factors such as weight, BMI, caloric intake, exercise, depressive symptoms, fatigue, Self-Care Mean Agency scores, and Body Image Scale scores.
Patient weight was found to be statistically significantly decreased in both direct individual and group education POEIs (P<.01) [23,24,28,29].Petasne Nijamkin et al [29] and Nijamkin et al [28] included 144 patients in a group education setting and reported weight loss in patients who received a POEI 12 months postoperatively (P<.001).Kalarchian et al [23,24], using a structured intervention, included 40 patients in a direct individual education method and had patients lose weight in the POEI arm at 4 months (P=.003).
BMI was also found to be statistically significantly decreased in patients provided with direct group education or coaching (P<.01) [28] and in patients provided with a POEI using a mobile app (P<.05) [22].Deniz Doğan and Arslan [22] included 51 patients in the mobile app intervention and recorded a reduced BMI (P<.05) in the first 3 months postoperatively.
Caloric intake was statistically decreased (P<.05) when patients received a direct individual education POEI [24].An increase in exercise and a decrease in depressivesymptoms was found to be statistically significant (P<.01) when patients received a direct group education POEI [28,29].In the study by Nijamkin et al [28], exercise was measured via the Short Questionnaire to Assess Health Enhancing Physical.In the study by Petasne Nijamkin et al [29], depression was measured via the Beck Depression Inventory questionnaire and demonstrated a decrease in depression incidence after 12 months (P<.001).
Patient fatigue postoperatively was decreased when patients were given an educational presentation (P=.008) [33].Self-Care Mean Agency scores and Body Image Scale scores had no significant increase in patients when provided with a POEI via a mobile app [22].Deniz Doğan and Arslan [22] assessed Self-Care Mean Agency scores via a Likert-type Scale ranging from 0 to 4 with 35 items and Body Image Scale via a Likert-type scale ranging from 1 to 5 with 40 items.The direct group education intervention had a significant positive effect on weight, BMI, exercise, and depressive symptoms for patients after laparoscopic bariatric surgery, suggesting potential future physician consideration as a preferred intervention choice [28,29].

Direct Individual and Direct Group Education
POEIs included direct individual education, direct group education, video education, multimedia presentations, and mobile apps.Direct individual education methods included supervised and personalized training programs lasting from 1 to 3 months postoperatively as well as nutritional guidance delivered by nurses and physicians via in-person sessions or telehealth [19,27].POEIs that incorporated personalized training programs led to a decrease in the rate of severe complications (P<.05) and anxiety (P<.05) [19,27].Direct individual education also involved personalized preoperative education brochures and advice given by the patient's surgeon, which reduced nausea postoperatively (P<.05) [21].In addition, patients received postoperative portion-controlled meal deliveries and counseling over 4 weeks, provided by a registered dietitian, leading to weight loss (P<.01) and reduced caloric intake (P<.05) [24].Direct group education POEIs for bariatric surgeries involved 4 to 6 comprehensive lifestyle and behavioral or motivational sessions with the research teams and registered dieticians, and it resulted in a significant decrease in weight, BMI, and depressive symptoms (P<.01) and a significant increase in exercise (P<.01) [28,29].

Educational Videos and Multimedia Presentations
Video education modalities involved short animations that served the goal of assuaging anxiety and operative fear.These animations were shown to the patient up to 3 times preoperatively and daily postoperatively for 1 week, which led to decreases in anxiety, pain, and nausea (P<.01) [18,34].Likewise, preoperative multimedia presentations administered by registered nurses in the form of CDs and additional animations or brochures provided additional material to the patient before surgery, educating patients about the primary purpose of the surgery, preoperative examinations, and potential complications [20,30,33].These POEIs led to statistically significant decreases in anxiety and fatigue in patients undergoing laparoscopic cholecystectomy (P<.01) [20,30,33].

Mobile App
Finally, mobile app POEIs developed by the research teams allowed patients to access educational resources on their own time, and it included information about postsurgical care, weight tracking, nutrition, and exercise regimens with recovery goals during the first 3 months of surgery [22,26].Patients receiving this POEI experienced a decrease in BMI (P<.05); however, there was no statistically significant decrease in Self-Care Mean Agency scores, Body Image Scale scores, or postoperative patient compliance [22,26].

Principal Findings
In this systematic review of RCTs, 17 studies were included, analyzing a total of 1831 patients.Approximately 38% (3/8) of the laparoscopic cholecystectomy studies tested an educational

RenderX video, which led to a statistically significant decrease in postoperative anxiety, pain, and nausea [18,30,32,34].Nearly 50% (7/17) of the studies included in this review found that direct individual education improved outcomes for a variety of surgical procedures.Educational videos were most effective at reducing anxiety, nausea, and pain after surgery [18,30].In about 33% (2/6) of the studies on laparoscopic gastric bypass, direct group education was shown to be effective in improving weight, BMI, exercise, and depressive symptoms.To decrease postsurgery complication rates, ICU admission, as well as first exhaust and defecation time for patients, direct individual education POEIs can be implemented before surgery [25,27].

Direct Individual Education and Direct Group Education
Direct individual education was the most effective POEI across all included procedure types: laparoscopic cholecystectomy, bariatric surgery, and colectomy [19,21,[23][24][25]27,31]. Direct individual education has been shown to be effective in other surgical procedures as it provides patients with a personalized intervention tailored to their specific needs, which allows for patients to freely communicate and better understand their condition, treatment plan, and postoperative care [36,37].For example, in hip or knee arthroplasty, patient education led to a significantly shorter length of stay (P<.001), suggesting that the effectiveness of one-on-one education or coaching found in this review is not only limited to abdominal laparoscopic procedures [10].Direct group education had significantly improved outcomes across laparoscopic gastric bypass for weight, BMI, exercise, and depressive symptoms (P<.01) [28,29].A group setting allows for bonding with others and building a support system, which can be a critical influence toward lifestyle changes necessary for improved outcomes after bariatric surgery [38,39].In a prior systematic review analyzing POEIs in patients undergoing major surgery, the authors found that increased frequency of message exposure improved outcomes; however, this review suggests that the frequency of message exposure may not be as important as POEI type since all frequencies of one-on-one and group education or coaching POEIs had similar effectiveness across all procedure types [13].
Although the included studies incorporated in-person direct individual and group education, there are emerging technologies, such as virtual reality, that offer a new avenue to provide patients with individual or group education and coaching through a distanced modality [40,41].

Educational Videos and Multimedia Presentations
POEIs with educational videos or a presentation had the most statistically significant improvements on anxiety, pain, and fatigue after laparoscopic cholecystectomy (P<.01) [18,20,30,[32][33][34].The use of videos to educate patients allowed for increased standardization, cost-effectiveness, and accessibility due to the prerecorded nature of this intervention that can be applied broadly throughout multiple disciplines of medicine [42,43].Incorporation of educational videos also allows for patients to receive the POEI from the convenience of their own home and reduces health care inequity related to access to transportation and proximity to the hospital [44][45][46].Preoperative video education has been shown to improve physical symptoms in the literature, as suggested by this review; however, this POEI has also been shown to improve knowledge, preparedness, satisfaction, psychological well-being, quality of life, and health care use in other surgery types [47].
Presentations allow for patients and caregivers to engage with the material and ask questions to better understand the content [48].Both forms of POEI have demonstrated effectiveness in improving specific patient outcomes based on the content of the education; if the content is tailored toward focusing on additional aspects of the patient's postoperative recovery, more patient outcomes may be improved [49].

Mobile Apps
Newer forms of technology are also being tested for POEIs; however, more development is required within this area.In the 2 interventions that leveraged a mobile app for their POEI, there was improvement in BMI (P<.01); however, no statistically significant improvement was observed in Self-Care Mean Agency scores, Body Image Scale scores, or postoperative patient compliance [22,26].Although there were limited significant improvements in patient outcomes while using mobile apps, coupling newer technology with aspects of tested POEIs, such as in-person education, educational videos, or presentations, may be a feasible option to optimize patient outcomes after laparoscopic abdominal surgery.Use of mobile apps in plastic surgery has been shown to significantly improve understanding of the surgery and postoperative patient compliance; this suggests that this modality of POEI has the potential to also improve patient quality outcomes for abdominal laparoscopic procedures if researched further [14].Benefits of using technology through mobile apps, virtual reality, or artificial intelligence may provide increased accessibility to populations with limited mobility or access to clinical settings.These forms of communication can serve as a vital platform for enhancing the patient-physician rapport [50][51][52][53].There are challenges associated with implementing these tools as the technology of these POEIs encompasses the associated expenses, accessibility, and maintenance.In addition, these platforms will require extensive training to ensure a user-friendly platform for different patient populations [54,55].

Limitations
This study can be considered in light of the following limitations.First, the tools to report patient outcomes were not consistent across the included studies, thus a meta-analysis or further synthesis is not possible.Second, only laparoscopic cholecystectomy, bariatric surgery (ie, gastric bypass and gastric sleeve), and colectomy surgeries were included because these were the only available surgery types with RCTs published regarding POEI.The heterogeneity of the included studies within the review provides a more diverse and holistic review of the published POEIs, which allows a narrative analysis of the pros and cons of individual interventions in each type of surgery included; however, it limits the ability to statistically compare the interventions to determine the most efficacious POEI in laparoscopic abdominal surgery.There are numerous types of abdominal laparoscopic surgeries where POEI may be beneficial, but they were not included in this systematic review due to a lack of published RCTs.Some included studies did not report all aspects of the POEI, such as information regarding the process of developing the education content or the provision of training, supervision, or assistance with the POEI, including if there was any prototype testing or stakeholder feedback through co-design sessions.This limited the quantification of the effects of these features and their relationship with outcomes as there was significant variability in the published literature.Furthermore, the included studies may have been used for a more comprehensive, multidisciplinary intervention, confounding their direct impact on patient outcomes.However, this study provides informative insights into the current knowledge base pertaining to POEI and its applications in the field of abdominal laparoscopic surgeries.

Conclusions
This systematic review analyzed 17 RCTs that demonstrated the effect of POEIs on postoperative patient outcomes after abdominal laparoscopic surgeries.A total of 1831 patients undergoing laparoscopic cholecystectomy, bariatric surgery (ie, gastric bypass and gastric sleeve), or colectomy were included in this analysis, and 15 studies reported a statistically significant improvement in at least 1 patient postoperative outcome.Overall, direct individual education was the most effective POEI across all included procedure types; direct group education had the most significantly improved outcomes primarily among bariatric surgeries.POEIs that incorporated educational videos or presentations demonstrated the most statistically significant improvements in anxiety, pain, and fatigue following laparoscopic cholecystectomy.Direct education, whether individual or group based, has been shown to have a more positive impact on postoperative outcomes than newer POEIs, such as mobile apps.The practicality of this allows surgeons to personalize the health care delivered to each patient and provide the appropriate POEI based on which outcomes are more important for that patient.Future directions include expanding the use of POEIs to additional surgical procedures and further testing POEIs that incorporate more recent technology.
