Quality of life aspects of intermittent catheterization in neurogenic and non-neurogenic patients: a systematic review on heterogeneity in the measurements used.

BACKGROUND

Clean intermittent catheterization (CIC) is the golden standard in patients with lower urinary tract dysfunction, leading to bladder emptying problems, due to neurogenic or non-neurogenic causes. CIC affects patient Quality of Life (QoL) both positively and negatively.

OBJECTIVES

The aim of this systematic review is to determine which measurements are used to report on the QoL of patients who are on CIC in the currently available literature, to determine the overall QoL of patients who are on CIC and lastly, to determine whether QoL in patients who are on CIC is dependent on the underlying cause (neurogenic vs non-neurogenic).

DESIGN

This systematic review was conducted following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

DATA SOURCES AND METHODS

The Embase, Medline, Web of Science Core Collection, CINAHL, Google Scholar, and the Cochrane CENTRAL register of trials databases were systematically searched for relevant publications until March 2023.

RESULTS

A total of 4430 abstracts were screened and 43 studies were included. Studies were published between 1993 and 2022 and consisted of only neurogenic patients in 22 studies, the others included a mixed population. The included patient populations and the used measurements/tools were heterogeneous. There were 21 measurements/tools used to measure QoL, of which 3 were not validated. One questionnaire was developed to measure QoL in patients on CIC (intermittent self-catheterization questionnaire). Other measurements were suitable for general health-related QoL, to evaluate neurogenic bladder symptoms or incontinence oriented.

CONCLUSION

The 43 included studies showed a great variety of used tools to measure QoL in patients on CIC due to neurogenic and non-neurogenic causes. Because of lacking uniformity of the measured aspects of QoL, the different included studies could not be compared and subgroup analysis was not performed. Recommendations for future research and practice are provided.
