Time Burden of Bladder Management in Individuals With Spinal Cord Injury

Integrating Patient Preferences with Guideline-Based Care in Neurogenic Lower Urinary Tract Dysfunction After Spinal Cord Injury

Individual and social factors are important for clinical decision-making in patients with neurogenic bladder secondary to spinal cord injury (SCI). These factors include the availability of caregivers, social infrastructure, and personal preferences, which all can drive bladder management decisions. These elements can be overlooked in clinical decision-making; therefore, there is a need to elicit and prioritize patient preferences and values into neurogenic bladder care to facilitate personalized bladder management choices. For the purposes of this article, we review the role of guideline-based care and shared decision-making in the SCI population with neurogenic lower urinary tract dysfunction.

Urinary Catheters: Materials, Coatings, and Recommendations for Selection

Urinary catheters have been used for more than 3000 years, although materials have changed from wood to silver to rubber. Research continues to try and find the optimal catheter materials, which improve safety and quality of life. Advantages when comparing newer catheter materials are not always obvious but catheters coated with a hydrophilic layer may reduce urethral trauma and the incidence of urinary tract infections. However, extrapolation of the data is limited by lack of end-point standardization and heterogenous populations.

The Role of Upper Extremity Motor Function in the Choice of Bladder Management in Those Unable to Volitionally Void due to Neurologic Dysfunction

It is estimated that 425,000 individuals with neurologic bladder dysfunction (spinal cordinjury, spina bifida and multiple sclerosis) are unable to volitionally void and must rely oncatheter drainage. Upper extremity (UE) motor function is one of the most important factors indetermining the type of bladder management chosen in individuals who cannot volitionally void. Novel bladder management solutions for those with impaired UE motor function and concurrent impairments involitional voiding continue to be an area of need. Those with poor UE motor function more often choose an indwelling catheter, whereas those with normal UE motor function more often choose clean intermittent catheterization.

Do improvements in upper extremity motor function affect changes in bladder management after cervical spinal cord injury?

INTRODUCTION

One of the most important predictors of clean intermittent catheterization (CIC) adoption after spinal cord injury (SCI) is upper extremity (UE) motor function at discharge from rehabilitation. It is not clear however if post-discharge improvements in UE motor function affect future bladder management decisions.

METHODS

We assessed persons with cervical SCI in the National Spinal Cord Injury Dataset for the years 2000-2016 who underwent motor examination at discharge from rehabilitation and again at 1-year follow-up. Individuals were stratified based on a previously described algorithm which categorizes the ability to independently perform CIC based upon UE motor scores. Improvements in the predicted ability to self-catheterize over the first year after rehabilitation discharge were evaluated in relation to bladder management.

RESULTS

Despite 15% of our SCI cohort improving from "less than able to independently catheterize" to "able to independently catheterize", more patients in the overall cohort dropped out of CIC (175/643 = 27.2%) than adopted CIC (68/548 = 12.4%) (P < .001). We found that in those initially categorized as "less than able to independently catheterize" at the time of rehabilitation discharge, CIC adoption was not significantly different at 1-year follow-up whether or not there was motor improvement to "able to independently catheterize" (12.7% vs 9.2% respectively, P = 0.665). Between these two groups, CIC dropout was also equivalent (34.3% vs 30.0% respectively, P = 0.559).

CONCLUSIONS

In the first year after rehabilitation, more overall SCI patients transition away from CIC than convert to CIC. Significant improvements in UE motor function during the first year after rehabilitation discharge do not appear to affect bladder management decisions.

Hygiene management of intermittent self-catheterization using reusable silicone catheters in people with spinal cord lesions: A cross-sectional Internet survey in Japan

OBJECTIVES

To investigate hygiene management and catheter maintenance of reusable silicone catheters for intermittent self-catheterization (ISC) in Japan and examine their relationship with symptomatic urinary tract infection (sUTI).

METHODS

We conducted a cross-sectional Internet survey of people performing ISC using reusable silicone catheters owing to spinal cord lesions in Japan. Hygiene management and catheter maintenance of reusable silicone catheters and the incidence and frequency of sUTI were evaluated. We also examined the significant risk factors for sUTI.

RESULTS

Of 136 respondents, 62 (46%), 41 (30%), and 58 (43%) washed hands with water, washed hands with soap, and cleaned or disinfected the urethral meatus every time or most of the time before ISC, respectively. No significant difference was observed in the incidence and frequency of sUTI between respondents who adhered to these procedures and those who did not. There were no significant differences in the incidence and frequency of sUTI in respondents who changed their catheters every month and in those who changed their preservation solution within 2 days compared with those who did not. In multivariate analysis, pain during ISC, inconvenience of indoor mobility, bowel management problems, and participants' feeling of never having received instruction on catheter replacement were significant risk factors for sUTI.

CONCLUSIONS

There are individual differences in hygiene management and catheter maintenance of reusable silicone catheters, but the influence of these differences on the incidence and frequency of sUTI is not clear. Pain during ISC, bowel management problems, and inadequate instruction on catheter maintenance procedures are factors associated with sUTI.

Internal and External Barriers to Bladder Management in Persons with Neurologic Disease Performing Intermittent Catheterization

People living with neurogenic lower urinary tract dysfunction (NLUTD) often have to use clean intermittent catheters (CIC) to manage their bladder function. The use of catheters presents multiple unique challenges, based on both the person's inherent characteristics and on the external limitations imposed by public toilets. We review the impact of age, sex, upper limb function, caregiver assistance, time required to perform CIC, and urinary incontinence on CIC in NLUTD, with special reference to their interaction with societal and public health factors. Public toilet limitations, such as lack of availability, adequate space and special accommodation for CIC, cleanliness, and catheter design are also reviewed. These potential barriers play a significant role in the perception and performance of bladder care in people living with NLUTD.

Prediction of Lower Urinary Tract, Sexual, and Bowel Function, and Autonomic Dysreflexia after Spinal Cord Injury

Spinal cord injury (SCI) produces damage to the somatic and autonomic pathways that regulate lower urinary tract, sexual, and bowel function, and increases the risk of autonomic dysreflexia. The recovery of these functions has a high impact on health, functioning, and quality of life and is set as the utmost priority by patients. The application of reliable models to predict lower urinary tract, sexual, and bowel function, and autonomic dysreflexia is important for guiding counseling, rehabilitation, and social reintegration. Moreover, a reliable prediction is essential for designing future clinical trials to optimize patients' allocation to different treatment groups. To date, reliable and simple algorithms are available to predict lower urinary tract and bowel outcomes after traumatic and ischemic SCI. Previous studies identified a few risk factors to develop autonomic dysreflexia, albeit a model for prediction still lacks. On the other hand, there is an urgent need for a model to predict the evolution of sexual function. The aim of this review is to examine the available knowledge and models for the prediction of lower urinary tract, sexual, and bowel function, and autonomic dysreflexia after SCI, and critically discuss the research priorities in these fields.

Variation in Provider Practice Patterns and the Perceived Need for a Shared Decision-making Tool for Neurogenic Lower Urinary Tract Dysfunction

OBJECTIVE

To evaluate neurogenic lower urinary tract dysfunction (NLUTD) care providers' current practice patterns, their perceived need for a shared decision-making tool for NLUTD management.

METHODS

We developed an electronic survey to assess multiple factors surrounding NLUTD management including practice patterns, perceived need for a decision aid and willingness to use it. Prior to survey dissemination, a panel of expert NLUTD care providers reviewed and provided a critique of the survey. It was delivered via email to the members of the Genitourinary Reconstructive Surgeons, and the Society of Urodynamics, female pelvic medicine and urogenital reconstruction between March and May 2022.

RESULTS

A total of 117 NLUTD care providers from 11 countries participated in this survey. Most participants were urologists (n: 109, 93%) working at academic teaching hospitals (n: 82, 70%). The most common treatments the providers had provided for stress urinary incontinence and detrusor overactivity were sling procedures (n: 76, 65%) and anticholinergics (n: 111, 95%). Participants believed that NLUTD management can be highly patient-specific and extensively vary from one individual to another. Most participants believed that patients performing clean intermittent catheterization have better QoL compared to those utilizing indwelling urinary catheters (n: 81, 69%). Participants believed there is a need for a NLUTD decision aid, and they expressed their willingness to use one if available.

CONCLUSION

We found discordances between guideline recommendations, provider practice patterns, and patient-reported outcome measures and essential attributes that indicated the need for a decision aid to improve patient-provider communication and shared decision-making in NLUTD management.
