Urge incontinence in elderly people: factors predicting the severity of urine loss before and after pharmacological treatment

Nursing Staff Beliefs and Expectations About Continence Care in Nursing Homes

OBJECTIVE

The purpose of this qualitative study was to consider the current beliefs of nursing assistants and directors of nursing about management of urinary incontinence (UI) among the residents in nursing homes.

DESIGN

This was a qualitative study using purposive sampling and a focus group methodology.

SETTING AND SUBJECTS

Three focus groups including 38 participants were held in 2 different regions. Two of the focus groups comprised nursing assistants and 1 comprised directors of nursing.

METHOD

The focus groups were facilitated by 2 different advanced practice nurses (BR and LJK), and 2 similar interview guides were used: 1 for the nursing assistants and 1 for the nurses. The interviews were tape recorded and transcribed verbatim; data were analyzed via content analysis.

RESULTS

Ten themes were identified from the data; 3 focused on resident factors that influence UI, 4 related to staff and family contributors to UI, and 3 focused on recommendations to improve UI management in the nursing home setting.

CONCLUSIONS

The findings from this study can be used to guide interventions to decrease or eliminate barriers to continence care and thereby facilitate the implementation of clinical practice guidelines and evidence-based interventions to improve urinary continence among nursing home residents.

Urgency is the Core Symptom of Female Overactive Bladder Syndrome, as Demonstrated by a Statistical Analysis

PURPOSE

We determined overactive bladder symptoms in combination with other lower urinary tract symptoms and illustrated their relationships using a statistical analysis. Furthermore, we also describe the potential contributory factors and adaptation strategies in patients that are associated with overactive bladder subtypes.

MATERIALS AND METHODS

A total of 1,930 women with a mean age +/- SD of 46 +/- 15 years (range 15 to 91) with troubling lower urinary tract symptoms were successfully interviewed with a validated questionnaire at the urology and urogynecology clinics at 14 medical centers in Taiwan. The questionnaire was constructed to evaluate 6 lower urinary tract symptoms and 7 adaptation strategies. A log linear statistical model and multiple logistic regression analysis were used to assess the associations among lower urinary tract symptoms and the potential overactive bladder contributory factors, respectively.

RESULTS

No single or isolated symptom presented in patients with overactive bladder. Most patients reported a combination with other lower urinary tract symptoms. These female patients can be categorized into 3 groups, including 1 is associated with dry symptoms (urgency, frequency and nocturia), 1 associated with wet symptoms (urgency, urge incontinence and mixed stress incontinence) and a small group that may have overactive bladder symptoms combined with voiding difficulty symptoms. in contrast to patients with dry overactive bladder (urgency associated with frequency and/or nocturia without urge incontinence), after multiple logistic regression analysis patients with wet overactive bladder (urgency with urge incontinence) had a greater average age and higher body mass index, and made more adaptation efforts (p <0.05).

CONCLUSIONS

We used statistical analysis to determine and suggest that urgency is the core symptom of female overactive bladder syndrome and there are 3 distinctive overactive bladder subtypes, which differ in their symptom combinations. Different symptom combinations and patient characteristics affect female adaptation to overactive bladder syndrome.

Tag F315

Urinary incontinence affects more than 50% of elderly patients in hospitals and in nursing homes. Of the estimated $16.3 billion spent annually, 90% is spent on management, whereas only 10% is spent on diagnosis and treatment. With their June 2005 release of the F315 tag, the Centers for Medicare and Medicaid Services are taking steps to change the circumstances of this disorder. This tag provides several guidelines for continence care. One of the most noticeable mandates is that of "restoring as much normal bladder function as possible." This mandate provides various novel opportunities for the WOC nurses and advanced practice nurses with WOC certification.

Describing bladder storage function: overactive bladder syndrome and detrusor overactivity

After a comprehensive review of terminology of lower urinary tract function/dysfunction, the International Continence Society (ICS) has recommended the use of the terms overactive bladder syndrome (OAB) and detrusor overactivity. Detrusor overactivity is defined as a urodynamic observation characterized by involuntary detrusor contractions during the filling phase that may be spontaneous or provoked. Detrusor overactivity is subdivided into idiopathic detrusor overactivity and neurogenic detrusor overactivity. Because detrusor overactivity is a urodynamic diagnosis, it is essential to record symptoms and signs during urodynamic studies to correlate them with any involuntary contractions. The ICS 2002 report describes 2 types of detrusor overactivity: (1) phasic, which may or may not lead to urinary incontinence; and (2) terminal, which is a single involuntary detrusor contraction that often results in complete bladder emptying. OAB, as defined by ICS 2002, is a new term and is a symptomatic diagnosis. OAB is defined as urgency, with or without urge incontinence, and usually with frequency and nocturia. The ICS endorsement of the term OAB recognizes that patients with this symptom syndrome are almost always treated by nonsurgical means on an empirical basis, ie, without a urodynamic confirmation of the presumed diagnosis, detrusor overactivity. The ICS believes that these terms are more intuitive and will make it easier for patients and physicians alike to understand. It is hoped that general use of the new ICS definitions will facilitate effective communications between patients and their physicians concerning their urologic dysfunctions.

Urge incontinence and impaired detrusor contractility in the elderly

Among the elderly, both urge incontinence and elevated residual urine are common. When they occur together, they present a challenging clinical problem, called detrusor hyperactivity with impaired contractile function (DHIC). Impaired detrusor contractility has two aspects: elevated post-void residual urine volume and reduced detrusor contraction strength. Geriatric urge incontinence, especially in combination with reduced bladder sensation, is associated with specific cortical abnormalities: frontal and global cortical underperfusion and cognitive impairment. We have investigated, in 73 elderly incontinent patients, whether either aspect of impaired contractility is associated with urge incontinence, reduced sensation or these cortical abnormalities. For post-void residual urine, there are no significant associations. Detrusor contraction strength, however, is significantly increased (not impaired) if there is urge incontinence, reduced bladder sensation, or cortical underperfusion. Thus, DHIC appears to be a coincidental occurrence of two common conditions with different etiological factors.

Quest for a detrusor overactivity index

PURPOSE

Urge incontinence, which is the predominant type of geriatric incontinence, is generally attributed to detrusor overactivity. However, detrusor overactivity is present in up to half of continent elderly individuals. We postulated that detrusor overactivity associated with urge incontinence would be more severe but there are no established criteria for judging severity. Using urge incontinence frequency as a yardstick and controlling for nonurodynamic contributing factors we sought intrinsic lower urinary tract parameters that reflect detrusor overactivity severity. We postulated that parameters in 1 or more of 5 domains would be important, namely characteristics of uninhibited contraction, bladder capacity, bladder proprioception, detrusor contractility and sphincter adequacy.

MATERIALS AND METHODS

We analyzed data on 79 community dwelling incontinent individuals older than 60 years old. All subjects had urge incontinence on a 4-day voiding record and underwent multichannel videourodynamics. We examined the associations of urge incontinence frequency with the postulated key factors.

RESULTS

Multivariable analysis revealed that 24-hour urine output and functional bladder capacity consistently predicted urge incontinence frequency. Bladder proprioception was significant in some models. Uninhibited contraction pressure was another predictor. Surprisingly higher uninhibited contraction pressure was associated with lower urge incontinence frequency. This negative correlation was more pronounced in a subgroup with a less adequate sphincter but absent in those with good sphincter function, implying that low uninhibited contraction pressure does not necessarily indicate less severe detrusor overactivity but rather reflects sphincter inadequacy in many patients. Age was not independently associated with urge incontinence frequency.

CONCLUSIONS

We identified functional bladder capacity as a measure of detrusor overactivity severity. The measure commonly used, namely uninhibited contraction pressure, is inappropriate because it is severely confounded by sphincter function, especially in older individuals. Furthermore, we confirmed that urine output, and possibly bladder sensation and sphincter strength modify the clinical manifestation of detrusor overactivity.

Urinary incontinence in the older man

Older men experience UI less often than older women, but the disruption and bother they experience because of UI is significant. Several anatomic differences between men and women account for different pathophysiology of incontinence. In men, overflow incontinence and detrusor instability predominate; stress incontinence is seen only in cases in which men have had prostate surgery. Reported symptoms of urgency and urge incontinence may be particularly difficult to interpret clinically in men because they might indicate detrusor instability or bladder outlet obstruction causing uninhibited contractions. The medical evaluation of UI is similar for men and women; men being evaluated for UI need a postvoid residual. Noninvasive measurement of urine flow may add to the diagnostic accuracy of detecting bladder outlet obstruction, but the results may not agree with results obtained by pressure-flow studies. Prostate surgery can result in UI, and biofeedback can be an effective treatment. Near-continual leakage after prostate surgery seems to be most responsive to artificial sphincter implantation. Male nursing home patients with UI present a different challenge in that mental and physical dysfunction must be addressed. Staff-dependent interventions are the most appropriate.
