Construction of pelvic floor muscle rehabilitation training program for patients undergoing laparoscopic radical prostatectomy.

Background: Laparoscopic radical prostatectomy (LRP) is the standard treatment for early localized PCa, of which urinary incontinence is the most common postoperative complication. Pelvic floor muscle rehabilitation training is recognized as the first line of intervention measures, but the existing rehabilitation training programs are not clear in the formulation process, the content is not unified, and the clinical operability is not strong. In order to better guide clinical pelvic floor muscle rehabilitation training after LRP and prevent and control urinary incontinence, this study constructed a pelvic floor muscle rehabilitation training program for LRP patients.
Methods: Literature analysis, qualitative interview, and an expert group meeting method were used to form the draft of pelvic floor muscle rehabilitation training program for LRP patients. On this basis, after 2 rounds of Delphi expert consultation, the research team modified and improved the program.
Results: The consultation experts involved in the 2 rounds were the same, 15 questionnaires were sent out, and 15 were recovered with an effective recovery of 100%. The expert authority coefficient was 0.87. In the second round of consultation, Kendall's harmony coefficient was 0.14 (P<0.001), the mean coefficient of variation of expert opinion was 0.07 (P<0.001), and the mean value of importance assigned to each item was 4.53-5.00 points. Finally, the pelvic floor muscle rehabilitation training program for LRR patients was formed. Including rehabilitation training evaluation, rehabilitation training advanced time and content, rehabilitation training form of three first-level indicators, 12 second-level indicators, 53 third-level indicators. Conclusions: The pelvic floor muscle rehabilitation training program for LRP patients developed in this study is scientific, reliable, safe and feasible, which can provide reference for clinical pelvic floor muscle rehabilitation training after LRP and prevention and control of urinary incontinence. 2022 Translational Cancer Research.

Introduction

Prostate cancer (PCa) is the most common urinary tumor in males in China (1). With the promotion of “Healthy China Action”, residents’ awareness of PCa screening is constantly improving, and early diagnosis and treatment of PCa have become the mainstream trend (2,3). Laparoscopic radical prostatectomy (LRP) is the standard treatment for early localized PCa (4,5), but almost all patients will experience urinary incontinence after catheter removal (6), with an incidence of 96.7%. The recovery rate fluctuates between 30% and 90% 1 year after surgery (7,8). Studies have shown that although urinary incontinence does not immediately endanger patients’ lives, it has a significant psychological impact and will cause social function defects to varying degrees (9). Pelvic floor muscle rehabilitation training is a first-line intervention for the prevention and treatment of urinary incontinence recognized by clinical guidelines (10), and its short-term effective rate can reach 50–70%, while a certain amount of training must be completed to achieve effectiveness (11,12). Pelvic floor muscle rehabilitation training includes Kegel exercises, pelvic floor muscle rehabilitation exercises, pelvic floor biofeedback training, pelvic floor electrical stimulation, acupuncture treatment, and so on (13-16). Kegel exercises and pelvic floor muscle rehabilitation can be done at home due to their simplicity and safety. Therefore, most of the existing pelvic floor muscle rehabilitation training programs for LRP patients incorporate Kegel exercises alone or on the basis of Kegel exercise combined with pelvic floor muscle rehabilitation exercise. However, the existing rehabilitation training program has some shortcomings, such as unclear formulation process, inconsistent content, and weak clinical operation, on account of which it fails to play a full role in clinical practice. In view of this, this study standardized and detailed the effectiveness evaluation, start time, course of treatment, specific operation methods, and frequency of pelvic floor muscle rehabilitation training for LRP patients, and constructed a pelvic floor muscle rehabilitation training program for LRP patients, providing reference for the clinical implementation of pelvic floor muscle rehabilitation training after LRP and the prevention and control of urinary incontinence.

Methods

Research group establishment

The research team consisted of 6 expert members and 2 project researchers. The expert members included 2 urologists, 2 nurses, and 2 rehabilitation therapists with the following credentials: working years (22.50±9.01); 1 undergraduate, 2 masters, 3 doctors; all held senior titles. The expert members were mainly responsible for guiding the design of the project and quality control of the research. The 2 project researchers were masters of nursing and rehabilitation, mainly responsible for literature research, compilation of consultation questionnaire, expert selection, distribution and recovery of questionnaire, and collation and analysis of consultation results. The study conformed to the provisions of the Declaration of Helsinki (as revised in 2013), and was approved by the Institutional Review Board of The First Affiliated Hospital of Soochow University [approval number: (2021)336].

Draft formation of pelvic floor muscle rehabilitation training program for patients undergoing LRP

Through literature review, qualitative interview, and expert group discussion, the first draft of pelvic floor muscle rehabilitation training program for LRP patients was formed. (I) Literature review: based on evidence-based nursing, the literature about pelvic floor muscle rehabilitation training after LRP was searched by computer, and the quality of the literature was evaluated, the level of evidence was classified and the level of recommendation was determined. A total of 12 studies were included, including 3 guidelines, 1 evidence summary, 6 systematic evaluations, and 2 original research papers. A total of 13 pieces of recommended evidence were summarized, of which 7 pieces were grade A and 6 pieces were grade B. The guidelines were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II). Systematic evaluation and expert consensus were conducted using the corresponding evaluation criteria [2016] of The Australian Joanna Briggs Institute Evidence-based Health Care Centre (https://jbi.global/). The quality of the original literature was evaluated according to the literature type (17). (II) Qualitative interview: Through interviews with 8 experts and 8 patients in related fields, the current situation of urinary incontinence and pelvic floor muscle rehabilitation training of patients after LRP was elucidated. After analysis, 6 themes are extracted: (i) almost all participants had urinary incontinence after catheter removal. (ii) Urinary incontinence seriously affects the quality of life of patients. (iii) Some patients do not know how to contract the pelvic floor muscles, which results in losing the best time to recover from urinary incontinence. (iv) The effect of pelvic floor muscle rehabilitation training was not significant in some patients, and the duration of urinary incontinence symptoms lasted more than 6 months after surgery. (v) The pelvic floor muscle rehabilitation training only adopts Kegel exercise, which is monotonous with random frequency. (vi) Medical staff for the whole process of patient guidance and supervision are insufficient. (vii) Some patients do not have WeChat, resulting in low promotion and utilization of WeChat information. It was suggested that how to improve the effect of pelvic floor muscle rehabilitation training should be considered when constructing the program, and systematic guidance and standard program should be constructed. (III) Expert group meeting: literature review and qualitative interviews were conducted to identify gaps between the best evidence and clinical practice, and a draft of the pelvic floor muscle rehabilitation training program was constructed after discussion at expert group meetings.

The determination the pelvic floor muscle rehabilitation training program for patients undergoing LRP

According to the first draft of pelvic floor muscle rehabilitation training program for LRP patients, an expert consultation questionnaire was made. The questionnaire includes research introduction, consultation form, basic information, and authority of experts. Likert grade 5 scoring method was used to correspond to 1–5 points according to “not at all important–very important”, and set “reason” and “suggestion” columns. Experts in urology clinical nursing, urology clinical medicine, and rehabilitation medicine from grade 3 and first-class hospitals in Suzhou, Nanjing, Shanghai, Nantong, and Xuzhou were selected. The selection criteria for experts included the following credentials: doctor of clinical medicine in urology, bachelor degree in clinical nursing, and rehabilitation medicine in urology; at least 10 years of professional experience; intermediate or above titles. All the experts provided informed consent to participate in the study voluntarily. Multiple rounds of expert consultation were conducted in the form of email or on-site research, and the consulting results were collated jointly by 2 project researchers. The expert group discussed and screened the indicators, and formulated the next round of expert consultation questionnaire. The screening criteria for indicators were the mean value of importance assignment >4.00, and the coefficient of variation <0.25.

Statistical analysis

The software SPSS 23.0 (IBM Corp., Armonk, NY, USA) was used for data statistical analysis in this study. The measurement data of experts’ general data were expressed as mean ± standard deviation, and the counting data were expressed as frequency and percentage. The significance score of each rehabilitation training index was expressed by mean, standard deviation, coefficient of variation, and full score rate. Expert positive coefficient was expressed by questionnaire recovery rate. The degree of expert authority was expressed by expert authority coefficient. The degree of coordination of expert opinions was expressed by coefficient of variation and Kendall harmony coefficient. A P value <0.05 was considered statistically significant.

Results

Experts’ general information

In this study, a total of 15 experts were selected to complete 2 rounds of consultation, including 6 urological nursing experts, 5 rehabilitation experts, and 4 urological medical experts. There were 7 males and 8 females; age (42.00±3.67) years old, working years (20.33±6.58) years; 5 doctors, 4 masters, and 6 undergraduates; all held senior titles.

Expert positive coefficient, degree of authority, degree of coordination of opinions

The 2 rounds of consulting experts in this study were the same, 15 questionnaires were issued, and 15 were recovered, with effective recovery rate of 100% and positive coefficient of experts of 100%. In the first round of consultation, 10 experts gave constructive opinions orally or in writing, and in the second round, 2 experts gave constructive opinions orally, with good participation.

The degree of expert authority was represented by the expert authority coefficient, which was the arithmetic mean of the expert’s familiarity with the index and the expert's judgment basis. In this study, the expert judgment basis of the 2 rounds of consultation was 0.94, the expert familiarity was 0.81, and the expert authority coefficient was 0.87 (>0.70), indicating that the expert authority was high.

The degree of coordination of expert opinions was expressed by Kendall harmony coefficient and variation coefficient. Kendall’s harmony coefficient was 0.13 and 0.14, P<0.001. The mean coefficient of variation of expert opinions in the 2 rounds of consultation was 0.08 and 0.07 (P<0.001), indicating a high degree of coordination of expert opinions in the 2 rounds of consultation.

Expert consultation results

In the first round of expert consultation, the mean value of importance assignment of first-level indicators was 4.93–5.00 points, the coefficient of variation was 0–0.05, and the full score rate was 93.33–100%. The mean value of importance of second-level indicators ranged from 4.53 to 4.93 points, the coefficient of variation ranged from 0.05 to 0.16, and the full score rate ranged from 60.00% to 93.33%. The mean value of significance of the third-level indicators ranged from 4.33 to 5.00 points, the coefficient of variation ranged from 0 to 0.21, and the full score rate was 53.33–100%. According to the screening criteria of indicators and the opinions and suggestions of consulting experts, the following indicators were modified after discussion by the research group: the advanced names of rehabilitation training programs were added to the second-level indicators, including “rehabilitation training learning period”, “rehabilitation training introductory period”, “initial rehabilitation training period”, “rehabilitation training middle period”, and “rehabilitation training consolidation period”; third-level indicators “told the patient to be in lateral decubitus position, with the evaluators fingers inserted into the anus so that they could feel the correct tightening” changed to “the patient was in lateral decubitus position”, telephone follow-up “the method of teaching is oral teaching” to “the method of teaching is a combination of oral teaching and video viewing”, “fly back training” changed to “superman flight training”. In Kegel level 1 exercise “intensity: under the condition of relaxing the muscles of the lower limbs, abdomen and buttocks, voluntarily contract and relax the muscles around the pubic bone and coccyx (perineum and anal sphincter), contract when inhaling deeply and relax when exhaling, all for 10 s. The above movements are conducted once” changed to “under the condition of relaxing the muscles of the lower limbs, abdomen and buttocks, voluntarily contract and relax the muscles around the pubic bone and coccyx (perineum and anal sphincter), keep breathing evenly, contract for 5 s, relax for 10 s, the above movements constituted one cycle”. In Kegel level 2 exercise, “intensity: under the condition of relaxing the muscles of the lower limbs, abdomen and buttocks, the muscles around the pubic bone and coccyx (perineum and anal sphincter) should be voluntarily contracted and relaxed. Contract when inhaling deeply and relax when exhaling, all for 10 s. The above movements constituted 1 cycle.” changed to “under the condition of relaxing the muscles of the lower limbs, abdomen and buttocks, voluntarily contract and relax the muscles around the pubic bone and coccyx (perineum and anal sphincter), keep breathing evenly, contract and relax for 10 s, and view the corresponding rehabilitation training video at the same time”.

In the second round of expert consultation, the mean value of importance assignment of first-level indicators was 4.93–5.00 points, the coefficient of variation was 0–0.05, and the full score rate was 93.33–100%. The mean value of importance of second-level indicators ranged from 4.53 to 4.93 points, the coefficient of variation ranged from 0.05 to 0.15, and the full score rate was 60.00–93.33%. The mean value of significance of the third-level indicators ranged from 4.53 to 5.00 points, the coefficient of variation ranged from 0 to 0.21, and the full score rate was 53.33–100%. According to the screening criteria of indicators and the opinions and suggestions of consulting experts, “rehabilitation training content is Kegel exercise level 1 + pelvic floor muscle rehabilitation exercise level 1” was changed to “rehabilitation training content is Kegel exercise Level 2 + pelvic floor muscle rehabilitation exercise level 2” in the learning period of rehabilitation training after discussion by the research group. In the consolidation period of rehabilitation training, “the form of outpatient face to face and telephone follow-up” was changed to “the form of outpatient face to face and telephone follow-up, with a total of 3 times of follow-up, namely, 3 weeks after removal of catheter, 6 months after surgery and 1 year after surgery”. In the second round of this study, consensus was reached and expert consultation was ended. The research team members modified and improved the program, and finally formed the pelvic floor muscle rehabilitation training program for LRP patients, including rehabilitation training evaluation, rehabilitation training advanced time and content, rehabilitation training form of three first-level indicators, 12 second-level indicators, and 53 third-level indicators. The results of the second round of expert consultation are shown in .

Discussion

The pelvic floor muscle rehabilitation training program for patients with LRP is scientific and reliable

In this study, the methods of literature analysis, qualitative interview, and expert group meeting were adopted to form the draft of pelvic floor muscle rehabilitation training program for LRP patients. On this basis, after Delphi expert consultation, research team members modified and improved the program, and finally established the pelvic floor muscle rehabilitation training program for LRP patients, which has sufficient theoretical basis and practical experience. The effectiveness evaluation, starting time, course of treatment, specific operation methods, and frequency of LRP patients’ pelvic floor muscle rehabilitation training in studies that have been conducted within China are not clear, and there have been few studies on LRP pelvic floor muscle rehabilitation intervention of Kegel exercise combined with pelvic floor muscle rehabilitation exercise. Therefore, it is important to listen widely and seek the advice of authoritative experts in urology and rehabilitation. In this study, the effective recovery rate of the 2 rounds of expert consultation questionnaires was high, at 100%. The proportion of experts who gave suggestions was 66.70% and 13.30% respectively, indicating that the experts had high enthusiasm and participation in the study. Overall, the 15 experts were (42.00±3.67) years old, working years were (20.33±6.58), and they held senior titles. Urology clinical nursing and rehabilitation medicine staff all held a bachelor’s degree or above, and those specializing in urology clinical medicine all held a doctor’s degree, which ensured their representation of the subject field. It is generally considered that the expert authority coefficient ≥0.7 is the acceptable reliability, and the expert authority coefficient in the second round of this study was 0.87, indicating that the expert authority is high. After the second round of consultation, the mean value of importance assigned to all indicators of the scheme was >4.00, and the coefficient of variation was <0.25, indicating a high degree of concentration of expert opinions. The significance test of Kendall’s harmony coefficient of the 2 rounds of expert consultation was statistically significant (P<0.001), indicating that the consistency degree of experts’ identification of indicators was acceptable, experts’ opinions tended to be consistent, and the results were credible.

The pelvic floor muscle rehabilitation training program for patients with LRP is safe and feasible

Kegel exercises are a pelvic floor muscle training method developed by Kegel in 1948 to restore pelvic floor function through pelvic floor muscle exercises. Its function is to enhance the pelvic floor muscles to support the bladder and urethra, and increase the strength of the urethral sphincter. When the abdominal pressure suddenly increases, the pressure can be transmitted to the bladder neck and urethra in the same proportion, so as to keep the urethra pressure greater than the bladder pressure and prevent the outflow of urine (18). A number of studies (19,20) have shown that timely and moderate Kegel exercise can achieve good results in the treatment of urinary incontinence after LRP, and this exercise is a safe treatment method, which can be used as the first choice for conservative treatment of urinary incontinence. However, Kegel exercise also has shortcomings, such as long treatment cycle, slow onset of action, monotonous action, and so on, which greatly reduce the compliance and enthusiasm of patients. In recent years, some researchers have added pelvic floor muscle rehabilitation exercises based on Kegel exercises, which emphasize core, respiration, and control (21). Studies have shown that such exercises are not only safe, but also greatly shorten the treatment period (22). The improvement of rehabilitation rate of urinary incontinence and the increase of exercise interest have fostered its wide promotion and application in maternal urinary incontinence (23). In view of this, this study formulated pelvic floor muscle rehabilitation exercise on the basis of Kegel exercise, which formulated 4 sets of movements, including inner thigh training, outer thigh training, hip training, and superman flight training. In this study, according to the physiological conditions of patients at different stages after LRP surgery, the content of rehabilitation training was quantified step by step, and a graded rehabilitation training program was developed. Kegel exercise and pelvic floor muscle rehabilitation exercise were divided into 2 levels according to exercise intensity, so as to increase patients’ confidence in continuous training and ensure the safety and feasibility of the program.

It is of great significance to construct a pelvic floor muscle rehabilitation training program for patients undergoing LRP

Urinary incontinence is the most common complication after LRP, and some patients will still have varying degrees of urinary incontinence within 1 year after surgery; however, most patients can significantly improve their urinary incontinence after positive pelvic floor muscle rehabilitation training, and only a very few patients need surgical intervention (15). The main causes of postoperative urinary incontinence are transient sphincter insufficiency, detrusor instability, and decreased bladder compliance during LRP, which can be recovered with scientific postoperative training (24). In order to reduce the trauma caused by surgery as much as possible, in addition to the fine operation during surgery, perioperative urine control technology should also be actively advocated in postoperative rehabilitation. However, in the multidisciplinary team, there is a shortage of clinicians in China, and the number of rehabilitation therapists is lower than the standard configuration, which makes it difficult to meet the needs of LRP patients’ pelvic floor muscle rehabilitation training. Although an important member, the rehabilitation tasks of nurses have not been clearly defined. The formation of this program ensures that nurses, therapists, and doctors have clear and clear practical guidance to effectively carry out pelvic floor muscle rehabilitation, which is of great significance for promoting patient rehabilitation, developing multidisciplinary teams, and highlighting the value of each discipline. In addition, compared with the shortage of rehabilitation therapists and clinicians, nurses take care of patients for 24 h, and are more actively involved in the guidance, supervision, and application of daily pelvic floor muscle rehabilitation training for patients. The LRP surgery has many advantages, such as less trauma and faster recovery, but because the anatomical position of the prostate is in a rich vascular cluster, postoperative hematoma forms easily, and bleeding can easily occur when a certain pressure is reached. Therefore, we must accurately grasp the training time point, and measure need to be promptly taken should bleeding occur. One of the common methods is bladder flushing, and it is recommended to refer to the continuous bladder flushing speed control card (25).

Conclusions

This study constructed a pelvic floor muscle rehabilitation training program for LRP patients through two rounds of expert consultation, including 3 first-level indicators (rehabilitation training evaluation, rehabilitation training advanced time and content, rehabilitation training form), 12 second-level indicators, and 53 third-level indicators. The consultation results were reliable, and the rehabilitation training program constructed was scientific, safe and feasible, which was suitable for the evaluation, planning and intervention of pelvic floor muscle rehabilitation training patients after LRP. It is important to note that the program is based on the cooperation of urologists, urological nurses and rehabilitation therapists, and has undergone systematic training and assessment. Next, we will carry out a randomized controlled study to evaluate the clinical application effect of the scheme.
