The challenges encountered with developing a valid and reliable urinary continence assessment form

The purpose of this study was to develop and validate a concise continence assessment form that can be completed by patients.
A prospective, descriptive, multi-site study was conducted at three major teaching hospitals over a 6 month period utilising a repeated measure design. The study was conducted over two stages: Stage One
consisted of developing the face validity and user friendliness of the instrument; Stage Two consisted of establishing the test-retest reliability of the instrument.
This paper discusses the process and results of the instrument development project. It highlights the clinical and statistical difficulties experienced in the development of the continence assessment form.

A guideline for the nursing assessment and management of urinary retention in elderly hospitalised patients

The objective of this project was to develop a guideline for the nursing assessment and management of urinary retention in hospitalised older adults. The guideline was developed from a review of the literature and from consultation with a multidisciplinary expert panel. These experts provided feedback through a structured process known as the Delphi technique. Based on findings from both sources, a final guideline was developed which provides a framework for the nursing assessment and management of urinary retention in hospitalised older adults. This foundational work provides the basis for further research and evaluation of the management of urinary retention.

Urinary incontinence

The reasons why urinary incontinence can be regarded as a women's health issue are explored. Emancipatory action research was used to develop an understanding of women's experience of UI. A number of important issues concerning the use of emancipatory action research in the social sciences in general, and nursing in particular, are addressed.

Natriuretic peptide regulation of the kidney and urinary bladder in the cane toad, Bufo marinus

The natriuretic peptide system of mammals is important in the control of blood volume but its function in non-mammalian animals is unclear. This study identified a functional natriuretic peptide system in an amphibian and showed that the hormones are involved in the control of fluid balance.

Residents' perspectives on urinary incontinence : a review of literature

Background: Individuals in residential aged care facilities experience urinary incontinence more than any other single population. Despite these factors, the impact of the condition on their quality of life, their perspectives of living with the condition, and their preferences for care have received little research attention.

Aim: To provide a descriptive overview of research about; the impact of urinary incontinence on residents’ quality of life; residents’ perspectives of having urinary incontinence; and their preferences for continence care’.

Design: A descriptive review of literature.

Method: A broad search was undertaken for qualitative and quantitative research that evaluated residents’ quality of life related to urinary incontinence; their perspectives on having urinary incontinence, and their preferences for managing it. Data were displayed in tabular format, summarized, and described.

Results: Ten studies were identified and reviewed (six qualitative and four quantitative). They reveal many residents’ value having independent bowel and bladder function, but believe that incontinence in inevitable and intractable. Some adopt self management strategies, however considerable barriers hinder their ability to maintain continence and manage incontinence. Residents often have low expectations, and hence decline further evaluation and treatment. Some express satisfaction with continence care even if this care is not consistent with their preferences. Little is known about how cognitively impaired residents perceive their condition. However some individuals with cognitive impairment respond with acute anxiety when carers’ attempt to provide continence care.

Conclusion: Residents’ perspectives on incontinence and preferences for continence care relate to low expectations for improvement. Such misconceptions should be addressed and residents and their family members should be given a range of options from which to choose. As urinary incontinence impacts on residents’ quality of life, it is also important that continence care is delivered in a participative and sensitive way.

Bayesian networks and decision trees in the diagnosis of female urinary incontinence

This study compares the effectiveness of Bayesian networks versus Decision Trees in modeling the Integral Theory of Female Urinary Incontinence diagnostic algorithm. Bayesian networks and Decision Trees were developed and trained using data from 58 adult women presenting with urinary incontinence symptoms. A Bayesian Network was developed in collaboration with an expert specialist who regularly utilizes a non-automated diagnostic algorithm in clinical practice. The original Bayesian network was later refined using a more connected approach. Diagnoses determined from all automated approaches were compared with the diagnoses of a single human expert. In most cases, Bayesian networks were found to be at least as accurate as the Decision Tree approach. The refined Connected Bayesian Network was found to be more accurate than the Original Bayesian Network accurately discriminated between diagnoses despite the small sample size. In contrast, the Connected and Decision Tree approaches were less able to discriminate between diagnoses. The Original Bayesian Network was found to provide an excellent basis for graphically communicating the correlation between symptoms and laxity defects in a given anatomical zone. Performance measures in both networks indicate that Bayesian networks could provide a potentially useful tool in the management of female pelvic floor dysfunction. Before the technique can be utilized in practice, well-established learning algorithms should be applied to improve network structure. A larger training data set should also improve network accuracy, sensitivity, and specificity.

Dietary salt intake assessed by 24 h urinary sodium excretion in Australian schoolchildren aged 5–13 years

Objective To measure total daily salt intake using 24 h urinary Na excretion within a sample of Victorian schoolchildren aged 5–13 years and to assess discretionary salt use habits of children and parents.

Design Cross-sectional study.

Setting Completed within a convenience sample of independent primary schools (n 9) located in Victoria, Australia.

Subjects Two hundred and sixty children completed a 24 h urine collection over a school (34 %) or non-school day (66 %). Samples deemed incomplete (n 18), an over-collection (n 1) or that were incorrectly processed at the laboratory (n 3) were excluded.

Results The sample comprised 120 boys and 118 girls with a mean age of 9·8 (sd 1·7) years. The average 24 h urinary Na excretion (n 238) was 103 (sd 43) mmol/24 h (salt equivalent 6·0 (sd 2·5) g/d). Daily Na excretion did not differ by sex; boys 105 (sd 46) mmol/24 h (salt equivalent 6·1 (sd 2·7) g/d) and girls 100 (sd 41) mmol/24 h (salt equivalent 5·9 (sd 2·4) g/d; P = 0·38). Sixty-nine per cent of children (n 164) exceeded the recommended daily Upper Limit for Na. Reported discretionary salt use was common: two-thirds of parents reported adding salt during cooking and almost half of children reported adding salt at the table.

Conclusions The majority of children had salt intakes exceeding the recommended daily Upper Limit. Strategies to lower salt intake in children are urgently required, and should include product reformulation of lower-sodium food products combined with interventions targeting discretionary salt use within the home.
