Associated factors of stress, urgency, and mixed urinary incontinence in a geriatric outpatient assessment of older women with hip fracture.

PURPOSE: Urinary incontinence (UI) is known to be common among older female hip fracture patients. Little is known about different subtypes of UI among these patients. Our aim was to identify factors associated with subtypes of UI in a cross-sectional design. METHODS: 1,675 female patients aged ≥ 65 and treated for their first hip fracture in Seinäjoki Central Hospital, Finland, during 2007-2019, were included in a prospective cohort study. Of these, 1,106 underwent comprehensive geriatric assessment (CGA), including questions on continence, at our geriatric outpatient clinic 6 month post-fracture. A multivariable-adjusted multinomial logistic regression model was used to examine factors associated with UI subtypes. RESULTS: Of the 779 patients included, 360 (46%) were continent and 419 (54%) had UI 6-month post-fracture. Of the women with UI, 117 (28%) had stress UI, 183 (44%) had urgency UI and 119 (28%) had mixed UI, respectively. Mean age of the patients was 82 ± 6,91. In multivariable analysis, depressive mood and poor mobility and functional ability were independently associated with stress UI. Fecal incontinence (FI) and Body Mass Index (BMI) over 28 were independently associated with urgency UI. Mixed UI shared the aforementioned factors with stress and urgency UI and was independently associated with constipation. CONCLUSIONS: Mixed UI was associated with most factors, of which depressive mood and impaired mobility and poor functional ability were shared with stress UI, and FI and higher BMI with urgency UI. CGA is key in assessing UI in older hip fracture patients, regardless of subtype.

Do urinary and double incontinence predict changes in living arrangements and mobility in older women after hip fracture? - a 1-year prospective cohort study.

BACKGROUND: Continence problems are known to be associated with disability in older adults. Costs of disability and resulting need for more supported living arrangements are high after a hip fracture. The aim was to examine pre-fracture urinary incontinence (UI) and double incontinence (DI, concurrent UI and fecal incontinence) as predictors of changes in mobility and living arrangements in older female hip fracture patients in a 1-year follow-up. METHODS: Study population comprised 1,675 female patients aged ≥ 65 (mean age 82.7 ± 6.8) sustaining their first hip fracture between 2007-2019. Data on self-reported pre-fracture continence status was collected. The outcomes were declined vs. same or improved mobility level and need for more assisted vs same or less assisted living arrangements 1-year post-fracture. Separate cohorts of 1,226 and 1,055 women were generated for the mobility and living arrangements outcomes, respectively. Age- and multivariable-adjusted logistic regression models were used to determine the associations of UI, DI, and other baseline characteristics with the outcomes. RESULTS: Of the patients, 39% had declined mobility or more assisted living arrangements at 1-year follow-up. Adjusting for age, both pre-fracture UI and DI were associated with changes in mobility and living arrangements. In the multivariable analysis, UI (OR 1.88, 95% CI 1.41-2.51) and DI (1.99, 95% CI 1.21-3.27) were associated with decline in mobility level while only DI (OR 2.40, 95% CI 1.22-4.75) remained associated with the need for more assisted living arrangements. CONCLUSIONS: Both pre-fracture UI and DI in older women are risk factors for declining mobility level, but only DI for more supported living arrangements 1-year post-hip fracture. UI likely develops earlier in life and might not necessarily be strongly associated with the onset or increasing disability in later years. DI may indicate more marked vulnerability and burden to patients as well as to formal and informal caregivers.

Urinary and double incontinence in older women with hip fracture - risk of death and predictors of incident symptoms among survivors in a 1-year prospective cohort study.

OBJECTIVES: To investigate the association of urinary incontinence (UI) and double incontinence (DI, concurrent UI and fecal incontinence) with one-year mortality among older female hip fracture patients and to identify predictors of incident UI and DI. DESIGN: A prospective cohort study SETTING AND SUBJECTS: 1,468 female patients aged ≥ 65 treated for their first hip fracture during the period 2007-2019 METHODS: Continence status was elicited at baseline and one-year post-fracture. Age- and multivariable-adjusted Cox proportional hazards and multinomial logistic regression models were used to determine the associations of incontinence with one-year mortality and to examine the associations of baseline predictors with incident UI and DI respectively. RESULTS: Of the women with no incontinence, UI and DI, 78 (13%), 159 (23%) and 60 (34%), died during follow-up. UI (HR 1.72, 95% CI 1.31-2.26) and DI (HR 2.61, 95% CI 1.86-3.66) were associated with mortality after adjusting for age. These associations lost their predictive power in multivariable analysis while age over 90, living in an institution, impaired mobility, poor nutrition, polypharmacy, and late removal of urinary catheter remained associated with mortality. Of continent women, 128 (21%) developed UI and 23 (4%) DI during follow-up. In multivariable analysis, impaired mobility was associated with incident UI (OR 2.56, 95% CI 1.48-4.44) and DI (OR 4.82, 95% CI 1.70-13.7), as well as living in an institution (OR 3.44, 95% CI 1.56-7.61 and OR 3.90, 95% CI 1.17-13.0). CONCLUSIONS AND IMPLICATIONS: Underlying vulnerability likely explains differences in mortality between continence groups and development of incident UI and DI.
