Abstract

INTRODUCTION

Urinary incontinence (UI), defined as the complaint of any involuntary loss of urine, is a major problem for adults, especially for older women.1–3) More than half of nursing home residents are incontinent2–5) and the prevalence of UI in residents of Turkish nursing homes is 30.0%–47.6%.6–8)

UI may occur in nursing home residents due to neurological diseases, urological and gynecological problems, psychological reasons, and functional impairments. These conditions may affect bladder control and voiding frequency.2) UI leads to hygiene and skin problems, sleep disturbances, and sexual activity disorders and impairs quality of life by causing negative psychological and social effects such as lack of self-esteem, shame, anxiety, depression, and social isolation.9,10) In addition, UI increases the workload of caregivers and health care costs in nursing homes.10)

Although UI is a problem with multifactorial etiology, it can be cured or ameliorated at a large scale with the implementation of appropriate methods, such as lifestyle regulation and behavioral therapy.2) However, many patients feel ashamed and embarrassed by their incontinence and consider UI a taboo subject. In addition, lack of knowledge about UI and a belief that it is a natural result of aging prevent older people, as well as their families and caregivers, from seeking medical help.9–13)

Kubik et al.11) suggested that improving knowledge about UI and treatment options would likely lead to increased care seeking. Therefore, a number of studies have investigated the level of knowledge regarding UI in different populations.1,12–23) Most of these studies were conducted on community-dwelling people of different age, sex, and race groups1,12,13,15–23) and few investigated the level of knowledge and practices about UI among nursing home staff.14) Despite being a very important and common problem, research on UI in nursing home residents, especially in Turkey, has mainly focused on its prevalence, correlations with mobility, and impact on quality of life.6–8,24–26) To our knowledge, no study has investigated UI knowledge among nursing home residents. Therefore, this study assessed the level of knowledge regarding UI among nursing home residents.

MATERIALS AND METHODS

This questionnaire-based cross-sectional study was conducted on the residents of three nursing homes in Muğla, Turkey, between November 2016 and February 2017. The study included volunteer participants and was performed in accordance with the principles of the Declaration of Helsinki. Administrative and ethical approvals for the study were obtained from the Muğla Family and Social Policies Provincial Directorate and the Scientific Research Ethical Board of Muğla Sıtkı Koçman University (Protocol number: 121), respectively.

Based on their formal registrations, there were a total of 208 residents in participating nursing homes. Some of these residents required specialized care, support, protection, and rehabilitation due to severe physical or mental deterioration and, thus, were being attended at the rehabilitation centers of these nursing homes. Therefore, the eligibility of the remaining 115 nursing home residents was assessed. Among them, 23 participants had visual/hearing problems at a level that prevented their participation in the study, 19 had scores ≤24 points on the Mini-Mental Test,27) and nine declined to participate in the study. As a result, 64 subjects fulfilled the inclusion criteria, signed the informed consent form, and were included in the study. The following information was recorded for these eligible individuals:

The severity, frequency, and type of UI were assessed using the Turkish version of International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF).29) The score range of this measure is 0–21 points, where higher scores indicate greater severity.

The nursing home residents’ level of knowledge about UI was assessed using the 14-item Incontinence Quiz (IQ) developed by Branch et al.16). The measure was translated into Turkish by Kara et al.15) and the Turkish version has been shown to be reliable and valid. The participants’ responses to each item on the IQ included “agree/disagree/ don’t know.” The correct answers were “agree” for the first, fourth, sixth, eighth, 10th, and 11th items and “disagree” for the second, third, fifth, seventh, ninth, 12th, 13th, and 14th items. Items marked as “don’t know” were scored as incorrect. Each correct answer was assigned 1 point and the total score ranged between 0 and 14 points, where higher scores indicate a higher level of knowledge about UI.15,16)

For statistical analysis, IBM SPSS Statistics for MacOSX, version 22.0 (IBM, Armonk, NY, USA) was used. Quantitative variables were described as means±standard deviation and qualitative variables as numbers and percentage. The Barthel Index and IQ scores of the continent and incontinent groups were compared by using Mann–Whitney U-tests. Statistical significance was set at an alpha level of 0.05.

RESULTS

The physical characteristics of the 19 female and 45 male nursing home residents are presented in Table 1. Their mean length of stay in the nursing home was 34.48±33.16 months (∼20 months for women and 40 months for men). Only 31.3% of the participants had a high school or university degree; the majority (68.7%) had primary education at most. The percentage of married participants was low and most participants were single (Table 1).

Table 1

Physical and sociodemographic characteristics of the participants

Only one of the participants (1.6%) was bedridden, 16 (25.0%) were independent with assistive equipment, and 47 (73.4%) were independent. None of the participants reported using a wheelchair, one used crutches (1.6%), and 15 (23.4%) used canes (Table 2). The mean Barthel Index score of the participants was 89.75±13.00 (minimum=50, maximum=100), indicating a moderate dependence in activities of daily living.28) The Barthel Index scores of participants with (88.48±13.69 points) and without (90.54±12.68 points) UI complaint were similar (p=0.440) (Table 2). According to obstetrical and gynecological history assessment of the female residents, the number of pregnancies and deliveries ranged from 0–8, none had delivered by Cesarean section, all had experienced natural menopause, and 31.6% had undergone gynecological surgery. In addition, one-third of the male residents (33.3%) reported having had prostate problem/surgery.

Functional status of the participants

Among all participants, 12 women and 13 men (39.1%) complained of UI. When incontinent participants were questioned regarding their treatment history for UI, 56.0% reported medical treatment, 40.0% had no treatment, and none had received physiotherapy (Table 3). Comorbid illnesses associated with UI and use of medication that may contribute to UI were reported by 48.7% of all participants and 56.0% of incontinent participants. Table 3 presents the comorbid illnesses associated with UI in incontinent women and men. Four incontinent residents had more than one comorbid illness associated with UI. Twenty-eight percent of incontinent participants reported that they were using diapers as a coping method with UI, while 72% reported no coping method. According to ICIQ-SF data of all nursing home residents, 18.8% had urge, 4.7% had stress, 7.8% had mixed, and 7.8% had other types of UI. Among incontinent participants, the most common type of UI was also urge incontinence (48.0%) (Table 3).

The mean ICIQ-SF score, which reflects the total score of the amount and frequency of UI and its impact on quality of life, was 8.08±4.24 points overall over 21 points among incontinent participants. The cut-off score for the Turkish ICIQ-SF is eight.29) Therefore, in this study, 50.0% of incontinent women and 15.4% of incontinent men had ICIQ-SF scores ≥8 points and were considered to have bothersome UI. Among incontinent men, 61.5% leaked urine approximately once a week or less, while 33.3% each of incontinent women leaked twice or three times a week and approximately once a day, respectively, according to the ICIQ-SF (Table 4).

None of the nursing home residents correctly answered all of the IQ questions. Their mean IQ score was 4.88±1.96 (minimum=1, maximum=9), indicating a low level of UI knowledge. Continent and incontinent residents had similar IQ scores (4.97±2.15 and 4.72±1.67 points, respectively) (p=0.564). The second (“involuntary loss of urine, often called leaky bladder or urinary incontinence, is one of the results of normal aging”) and 14th (“most people with involuntary urine loss talk to their doctors about it”) items on the IQ had the highest rates of incorrect responses (84.4%). These were followed by the third (“most people will involuntarily or accidentally lose control of their urine on a regular basis by the time they are 85”) and 12th (“involuntary urine loss is caused by only one or two conditions”) items, with incorrect response rates of 82.8% (Fig. 1). The items with the highest incorrect answer rates were related to the causes of UI and treatment seeking for the problem. The sixth item (“there are exercises that can help control urine if one leaks when they cough, sneeze, or laugh”) had the highest number of “I don’t know” responses and was related to knowledge of exercises to help urine control. The IQ items with the highest correct rates were the first (“most people who currently have involuntary urine loss live normal lives”) and 10th (“involuntary loss of urine can be caused by several easily treatable medical conditions”) items (70.3% and 60.9%, respectively) (Fig. 1).

DISCUSSION

This study, which assessed UI knowledge among nursing home residents in Muğla Province, Turkey, showed that the residents had poor knowledge of UI. Consideration of their sociodemographic characteristics, mobility status, and level of dependence in activities of daily living of the sample indicated that they were similar to related sample characteristics presented in various articles on individuals living in different Turkish nursing homes. Therefore, the sample in the present study reflects the general characteristics of Turkish nursing home residents.8,30,31)

The prevalence of UI in this study sample was 39.1% (63.2% in female and 28.8% in male), a slightly higher prevalence than that reported by Cankurtaran et al.8) in Kayseri nursing homes (34.5%) and slightly lower than that reported by Ergün et al.26) in İstanbul nursing homes (45%). Subject-related large-scale studies in the United States,32) Sweden,14) and Brazil10) showed prevalence rates of UI in nursing homes of 30%, 51.5%, and 58.9%, respectively. These findings indicate that UI is a common problem among the residents of nursing homes both in Turkey and other countries.

According to ICIQ-SF data, the most common type of UI was urge incontinence (18.8% of the whole sample and 48.0% of incontinent residents). This finding is consistent with those of the studies by Na et al.33) (44.3% urge) and Lee et al.34) (47.2% urge), which reported urge incontinence to be the most common type of UI in the older population. Analysis of the frequency of UI in incontinent residents revealed that 20.0% of the participants leaked urine approximately once a day, similar to the study sample assessed by Lee et al.34) In both studies, the percentage of participants leaking urine more frequently than once a day was low (16.0% in this study and ∼9% in the study by Lee et al.34)).

Analysis of the treatment approaches for UI indicated that the most common method was medical treatment (56.0%), 40.0% of the participants did not receive any treatment, and none received physiotherapy and/or behavioral therapy. However, in a large-scale study by Jumadilova et al.32) conducted at 378 skilled nursing facilities from across the United States, the methods commonly used for UI in the older people living in nursing homes included behavior training methods such as bladder training and timed voiding, while drug treatment was less frequent (8%) and only applied to individuals with very severe UI.

In this study, participants with UI generally did not use a coping method (72%) and only 28% were using diapers/ pads. This finding corresponds with those of Jung et al.,35) who reported that only 20% of older Alzheimer’s patients used diapers/pads. Göral Türkcü and Kukulu25) and Demirci et al.24) reported significantly higher percentages of participants in nursing homes using diaper/pads as a coping method for UI (71.6% and 86.4%, respectively). This discordance may be due to different UI severities in the investigated samples. The similar Barthel Index scores of participants with and without UI complaints in the present study indicates that the UI complaint was not so severe as to affect independence in daily activities, which may an explain the conflicting results regarding coping methods for UI. It is also possible that the participants excluded due to severe physical, cognitive, or mental deterioration in this study had more severe UI symptoms.

According to the results of IQ, which was used to evaluate knowledge of nursing home residents about UI, only 4.88 of the 14 items were given correct responses and no participants provided correct responses to all of the items. A number of studies have investigated UI knowledge in different populations by using either the IQ or other scales such as Prolapse and Incontinence Knowledge Quiz (PIKQ) and Urinary Incontinence Knowledge Scale.11–13,17–23) However, to our knowledge, no study has focused on UI knowledge among nursing home residents. The mean number of correct IQ responses was 9.29 (66.4%) in 18–30-year-old American women17); 6.16 in white and 5.46 in minority women11); and 4.85 in community-dwelling Korean-American women above 30 years of age.12) Shah et al.18) reported that more than half of the PIKQ items were correctly answered by gynecology and urogynecology patients. Richter et al.19) found that the level of knowledge about UI was 82% in young adults and was related to the high educational level of the participants. Liebergall-Wischnitzer et al.20) reported a moderate UI knowledge of community-dwelling Israeli women of child-bearing age, which increased with higher age and education level. The findings of these studies showed that knowledge about UI in nursing home residents in the present study was similar to that of community-dwelling Korean-American women above 30 years of age and lower than that in other samples. This may be due to differences in age, education, and sociocultural characteristics of the populations in these studies.

The analyses of correct and incorrect responses to IQ items revealed that most of the nursing home residents considered UI to be a natural result of aging, that not much could be done other than using a pad/diaper, and that the best treatment for UI was surgery. In addition, they were also unaware that exercises could help to control UI. Keller21) reported that women over 55 years of age had misconceptions about the causes and treatability of UI and that only 37% of women with UI sought treatment. Mandimika et al.22) reported a global lack of knowledge about UI risk factors, prevention strategies, and treatment options in community-dwelling women aged 19–98 years. Yuan and Williams13) and Day et al.23) also reported that both community-dwelling older individuals in China and community-dwelling women above 50 years of age had insufficient knowledge about the risk factors, symptoms, prevention, treatment and coping methods of UI and considered UI to be a natural result of aging. These findings of the previous studies are concordant with the findings of the current study, indicating the unmet educational needs relating to UI in different parts of societies.

To our knowledge, this study is the first to assess UI knowledge among nursing home residents; therefore, its findings are important for the literature. However, recruiting nursing home residents of only one city and not including nursing home residents from different geographical regions are limitations in this study. Therefore, it is necessary to validate these findings by evaluating UI knowledge in larger-scale studies including participants from nursing homes in different geographical regions.

The findings of the present study indicate the need to improve the knowledge and awareness of UI among nursing home residents. Educational programs developed for this purpose should focus on the causes, risk factors, coping methods, and treatment options of UI. In addition, health care professionals in nursing homes should be included in these educational programs and the feasibility of conservative treatment approaches such as physiotherapy and behavior training, which can be effective in UI management, should be improved.
