Postoperative complications and mobilisation following major abdominal surgery with vs. without fitness tracker-based feedback (EXPELLIARMUS): study protocol for a student-led multicentre randomised controlled trial (CHIR-Net SIGMA study group)

Postoperative Complications and Mobilization Following Major Abdominal Surgery With Versus Without Fitness Tracker-based Feedback (EXPELLIARMUS): A Student-led Multicenter Randomized Controlled Clinical Trial of the CHIR-Net SIGMA Study Group

OBJECTIVE

To determine whether daily postoperative step goals and feedback through a fitness tracker (FT) reduce the rate of postoperative complications after surgery.

BACKGROUND

Early and enhanced postoperative mobilization has been advocated to reduce postoperative complications, but it is unknown whether FT alone can reduce morbidity.

METHODS

EXPELLIARMUS was performed at 11 University Hospitals across Germany by the student-led clinical trial network SIGMA. Patients undergoing major abdominal surgery were enrolled, equipped with an FT, and randomly assigned to the experimental (visible screen) or control intervention (blackened screen). The experimental group received daily step goals and feedback through the FT. The primary end point was postoperative morbidity within 30 days using the Comprehensive Complication Index (CCI). All trial visits were performed by medical students in the hospital with the opportunity to consult a surgeon-facilitator who also obtained informed consent. After discharge, medical students performed the 30-day postoperative visit through telephone and electronic questionnaires.

RESULTS

A total of 347 patients were enrolled. Baseline characteristics were comparable between the 2 groups. The mean age of patients was 58 years, and 71% underwent surgery for malignant disease, with the most frequent indications being pancreatic, colorectal, and hepatobiliary malignancies. Roughly one-third of patients underwent laparoscopic surgery. No imputation for the primary end point was necessary as data completeness was 100%. There was no significant difference in the CCI between the 2 groups in the intention-to-treat analysis (mean±SD CCI experimental group: 23±24 vs. control: 22±22; 95% CI: -6.1, 3.7; P=0.628). All secondary outcomes, including quality of recovery, 6-minute walking test, length of hospital stay, and step count until postoperative day 7 were comparable between the 2 groups.

CONCLUSIONS

Daily step goals combined with FT-based feedback had no effect on postoperative morbidity. The EXPELLIARMUS shows that medical students can successfully conduct randomized controlled trials in surgery.

Influence of motivational interviewing on postoperative mobilization in the enhanced recovery after surgery (ERAS®) pathway in elective colorectal surgery - a randomized patient-blinded pilot study

PURPOSE

Early mobilization is an essential component of the Enhanced Recovery after Surgery (ERAS®)-pathway. However, a large percentage of patients fail to achieve the ERAS® recommended goal (360 min out of bed from post-operative day 1/POD1). Motivational Interviewing (MI) is an evidence-based type of patient-centered consultation to promote intrinsic motivation. This study aims to evaluate if MI can improve postoperative mobilization.

METHODS

This two-arm, patient-blinded pilot randomized controlled trial included ERAS®-patients undergoing elective bowel resections. Conversations were validated by MI Treatment Integrity. Two validated motion sensors (movisens) and self-assessments were used to measure mobilization (POD1-POD3: Time out of bed, time on feet and step count).

RESULTS

97 patients were screened, 60 finally included and randomized. Cumulatively across POD1-3, the intervention group (IG) was longer out of bed than the control group (CG) (median: 685 vs. 420 min; p=0.022). The IG achieved the ERAS®-goal of 360 min/day more frequently across POD1-3 (27.4% vs. 10.61%; p=0.013). Time on feet was 131.5 min/day (median per POD) in IG vs. 95.8 min/day in the CG (p=0.212), step count was 1347 in IG vs. 754 steps/day in CG (p=0.298).

CONCLUSION

MI could be conducted low threshold and was well accepted by patients. MI can improve mobilization in the context of ERAS®. Despite better performance, it should be noted that only 27.4% of the IG reached the ERAS®-compliance goal of 360 min/day. The findings of this pilot study stipulate to further test the promising perioperative effects of MI within a multicenter superiority trial.

The effect of an interactive robot on children's post-operative anxiety, mobilization, and parents' satisfaction; randomized controlled study

PURPOSE

To evaluate the effect of an interactive robot on Turkish children's post-operative anxiety, mobilization, and parents' satisfaction related to post-operative care.

METHOD

A randomized controlled study was conducted with 84 children who will undergo day surgery aged 5-10 years and their parents at a university hospital between June 2020-April 2022. The interactive robot was provided to accompany the children during the postoperative mobilization. Children in the control group received standard care during mobilization. Data were collected using the Personal Information Form, Children's State Anxiety (CSA), Parental Satisfaction Scale-Visual Analog Scale, and Mobilization Chart.

RESULTS

It was determined that the CSA score of the children in the control group were higher than the intervention group before their first mobilization after surgery (p = 0.005). During the first (p = 0.042) and second (p = 0.012) mobilization, it was determined that the mobilization duration of children in the intervention group was longer than the children in the control group. It was found that the parents of the children in the intervention group had a high level of satisfaction.

CONCLUSION

It has been determined that interactive robots positively affect postoperative mobilization in children undergoing day surgery, reduce the anxiety level of children before mobilization, and increase the duration of mobilization. In addition, the use of interactive robots increased parents' satisfaction with post-operative mobilization care.

PRACTICE IMPLICATIONS

Using interactive robots to reduce the stress and anxiety of children during the perioperative process can be a promising approach to improve their recovery by providing early mobilization.

The effects of preoperative alcohol, tobacco, and psychological stress on postoperative complications: a prospective observational study

Background

Postoperative complications occur frequently, despite progress in anesthetic pharmacology and surgical techniques. Although habits, such as alcohol and tobacco use, and mental health have been studied individually as modifying factors, few studies have examined the relationship between multiple lifestyle choices and postoperative complications in patients undergoing surgery. Hence, this study aimed to investigate the associations between unhealthy lifestyle choices and postoperative complications.

Methods

We included 730 patients who underwent surgery in our department between March 2015 and April 2016. Participants completed preoperative questionnaires, including the Alcohol Use Disorders Identification Test, Fagerström Test for Nicotine Dependence, and tests for psychological stress (6-item Kessler Psychological Distress Scale; Hospital Anxiety and Depression Scale). Multivariable logistic analysis was used to analyze the association of preoperative drug dependence and psychological stress with postoperative complications.

Results

Of the 721 cases analyzed, 461 (64%) were women. The median age of patients was 62 years (interquartile range: 48–71). At the time of surgical decision-making, 429 out of 710 respondents (60%) had a drinking habit, and 144 out of 693 respondents (21%) had a smoking habit during the preceding year. Seventy-nine patients had developed complications. Multivariable analysis revealed that old age (p = 0.020), psychological stress (p = 0.041), and longer anesthesia time (p < 0.001) were significantly associated with postoperative complications. Drinking or smoking variables were not associated with postoperative complications.

Conclusions

Preoperative psychological stress, as evaluated with the 6-item Kessler Psychological Distress Scale, is associated with the risk of postoperative complications.

The effect of mobilization protocol on mobilization start time and patient care outcomes in patients undergoing abdominal surgery

AIM

To evaluate the effect of mobilization protocol on mobilization start time, maintenance of mobilization and patient care outcomes in patients who underwent major abdominal open surgery.

BACKGROUND

Early mobilization in the first 24 hours postoperatively is recommended. Early mobilization is one of the evidence-based, effective nursing interventions that improve patient care outcomes.

DESIGN

A quasi-experimental non-randomised design was used in the study.

METHODS

In the study, the groups were followed sequentially and the data of the control group (n = 21) were collected before the intervention group (n = 21). The patients in the control group were mobilised postoperatively by the nurses according to the decision of the nurse and physician in the intensive care unit (ICU) on the day of the operation. There was no standard protocol for mobilization in the ICU. Mobilization training was given to the patients in the intervention group by the researcher nurse the evening before the operation, and a mobilization protocol was applied on the 0th postoperative day. Data on patient care outcomes were collected until the day when the patient was discharged from the hospital. The TREND checklist was followed.

RESULTS

According to the postoperative comparison of the patients in the intervention group to those in the control group, patients in the intervention group started mobilization earlier after admission in intensive care unit (6.22 ± 1.95 hours versus 12.21 ± 3.76 hours), had higher postoperative 0^th -day total mobilization time (128 minutes versus 34 minutes), had a shorter passage of flatus time and length of intensive care unit and hospital stay and had higher sleep quality and satisfaction scores.

CONCLUSIONS

The structured mobilization protocol is effective in the management of early mobilization and improvement of patient care outcomes.

RELEVANCE TO CLINICAL PRACTICE

mobilization protocols ensure that the mobilization process is maintained effectively.

Financial incentives and wearable activity monitors to increase ambulation after cystectomy: A randomized controlled trial

OBJECTIVES

Financial incentive programs are effective in increasing physical activity for overweight, ambulatory adults. We sought to determine the potential effect size and direction of financial incentives on ambulation after radical cystectomy.

MATERIALS AND METHODS

We performed a pilot randomized controlled trial of daily financial incentives to meet postoperative step goals among adults with Eastern Cooperative Oncology Group performance status ≤2 who underwent radical cystectomy for bladder cancer at a single center. Step counts were measured over a 3- to 14-day preoperative period and 30-day postoperative period using a wearable activity monitor. Postoperative daily step goals of 10%, 25%, 40%, and 55% of mean preoperative daily step counts were set for postoperative weeks 1 through 4, respectively. The primary outcome was the number of postoperative days on which the step goals were met. Secondary outcomes included the number of daily postoperative steps taken and the length of stay. Participants randomized to the intervention arm received $1.50 for every day the goal was met with a 20% chance of a $100 reward if the step goal was met on >75% of the first 30 postoperative days. Questionnaires assessing self-reported physical activity, disability, and social support were administered preoperatively at 30 days postoperatively.

RESULTS

Thirty-three patients were analyzed, 11 in the control and 22 in the intervention arms. There were no statistically significant differences between incentive and control arms for the primary outcome (4.5/30 days vs. 9/30 days, P = 0.53). Results after adjusting for differences in baseline characteristics were similar (RR 1.00, 95% CI 0.24-4.19, P = 1.00). There were also no differences in average daily postoperative steps (median 979 vs. 1191, 95% CI -810 to 1,400, P = 0.59), length of stay (7.5 vs. 7, 95% CI -2.7 to 5.1, P = 0.56), or self-reported measures of disability, activity, and social support.

CONCLUSIONS

While this trial was a pilot study and not powered to detect a difference between groups, there was no suggestion of any clinically important impact of this financial incentive on postoperative ambulation. While a fully-powered trial is feasible, given the small range of plausible benefit, such a trial would be unlikely to influence clinical practice.

Multicenter Prospective Cohort Study of the Patient-Reported Outcome Measures PRO-CTCAE and CAT EORTC QLQ-C30 in Major Abdominal Cancer Surgery (PATRONUS): A Student-Initiated German Medical Audit (SIGMA) Study

Background

The patient-reported outcomes (PRO) version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) and the computerized adaptive testing (CAT) version of the EORTC quality-of-life questionnaire QLQ-C30 have been proposed as new PRO measures in oncology; however, their implementation in patients undergoing cancer surgery has not yet been evaluated.

Methods

Patients undergoing elective abdominal cancer surgery were enrolled in a prospective multicenter study, and postoperative complications were recorded according to the Dindo–Clavien classification. Patients reported PRO data using the CAT EORTC QLQ-C30 and the PRO-CTCAE to measure 12 core cancer symptoms. Patients were followed-up for 6 months postoperatively. The study was carried out by medical students of the CHIR-Net SIGMA study network.

Results

Data of 303 patients were obtained and analyzed across 15 sites. PRO-CTCAE symptoms ‘poor appetite’, ‘fatigue’, ‘exhaustion’ and ‘sleeping problems’ increased after surgery and climaxed 10–30 days postoperatively. At 3–6 months postoperatively, no PRO-CTCAE symptom differed significantly to baseline. Patients reported higher ‘social functioning’ (p = 0.021) and overall quality-of-life scores (p < 0.05) 6 months after cancer surgery compared with the baseline level. There was a lack of correlation between postoperative complications or death and any of the PRO items evaluated. Feasibility endpoints for student-led research were met.

Conclusion

The two novel PRO questionnaires were successfully applied in surgical oncology. Postoperative complications do not affect health-reported quality-of-life or common cancer symptoms following major cancer surgery. The feasibility of student-led multicenter clinical research was demonstrated, but might be enhanced by improved student training.
