Abstract

Aim

This is a review of descriptive studies with incontinence as the primary focus in older people in care homes.

Background

Incontinence is prevalent among residents of care home populations.

Data sources

MEDLINE and CINAHL were searched from 1996 to 2007 using the highly sensitive search strings of the Cochrane Incontinence Review Group for urinary and faecal incontinence including all research designs. Search strings were modified to enhance selectiveness for care homes and older people and exclude studies involving surgical or pharmacological interventions. Searching of reference sections from identified studies was also used to supplement electronic searches. The Cochrane Library was searched for relevant systematic reviews to locate relevant studies from those included or excluded from reviews. The search was limited to English-language publications.

Methods

A systematic review of studies on the management of incontinence, promotion of continence or maintenance of continence in care homes was conducted in 2007–2009. This is a report of descriptive studies.

Results

Ten studies were identified that reported on prevalence and incidence of incontinence (urinary with or without faecal), policies, assessment, documentation, management or economic evaluation of its management. Use of incontinence pads and toileting programmes comprised the most common management approaches used. No studies were identified that attempted to maintain continence of residents in care homes.

Conclusions

Studies on maintaining continence and identifying components of toileting programmes that are successful in managing or preventing incontinence and promoting continence in residents of care home populations along with their economic evaluation are warranted.

Introduction

Incontinence is a prevalent condition affecting older people in community and institutional settings. Incontinence is estimated to affect from 31% to 70% of older people in care homes and incurs personal and institutional costs related to staff time, laundry, aids and appliances (McGrother et al. 2003, Fonda et al. 2005). A systematic review was undertaken to identify empirical research for the management of incontinence, promotion of continence or maintenance of continence in older people in care homes to describe and inform practice and future research. The overall review identified intervention studies and descriptive observational studies (as defined by Rawlins 2008) as the basis of an umbrella review. The review of interventions looking at effectiveness has been reported elsewhere due to its focus and number of studies available (under review). The purpose of this study is a report of descriptive studies that included urinary incontinence (UI) or continence status and its management or an economic evaluation as the primary focus.

Background

Clinical guidelines for the management of incontinence (Fantl et al. 1996, Button et al. 1998, NICE 2006, 2007), international consultation conferences (Abrams et al. 2009), systematic reviews (Eustice et al. 2000, Ostaszkiewicz et al. 2004a,b;, Wallace et al. 2004) and metastudy (Roe et al. 2007a,b;) have reviewed the evidence to inform and guide the management of incontinence. Incontinence has been defined as ‘the involuntary or inappropriate passing of urine and/or faeces that has an impact on social functioning or hygiene. It also includes nocturnal enuresis (bed wetting)’ (DH 2000, p. 7). The term care homes is generic and describes institutional settings that provide long term care for older people and includes nursing homes (giving nursing care), residential care homes (giving mainly social care) or mixed (giving both).

Management techniques are largely aimed at hospital or community populations. Research on the management of incontinence in care home populations has been undertaken, predominantly in the United States of America (USA) by designated research teams (for example, Schnelle et al. 1989, Colling et al. 1992, Ouslander et al. 1995) and their findings may not be transferable to other populations or settings where the organization, staffing and delivery of care may vary. Research on long-term follow-up to indicate if practices are sustained is generally unavailable. The focus of research has been on the management of incontinence whereas the maintenance of continence for older people that enter care homes has not featured.

The review

Aim

This study presents the review of descriptive empirical studies on the management of incontinence, promotion of continence or maintenance of continence in people aged 65 years and above in care homes with UI as the primary focus.

Objectives

The objective of this study is to identify care practices for the management of incontinence, promotion of continence or maintenance of continence in older people in care homes, and to provide a narrative synthesis of study designs, methods, findings and outcomes.

Design

A systematic review of studies that used quantitative or qualitative designs and methods was undertaken to provide a narrative synthesis. The PRISMA statement (formerly QOUROM) was used as a guide (Moher et al. 2009).

Search methods

Electronic searches were the prime method employed using MEDLINE and CINAHL via OVID (January 1966 to February 2007) to locate published studies (in English). Relevant studies awaiting assessment from updated searches to May 2010 are available (see supporting information Table S1 in the online version of the article in Wiley Online Library). Hand searching of reference sections from yielded studies and targeted journals for relevant references identified supplemented the electronic searches. The Cochrane Library was also searched for relevant systematic reviews to locate relevant studies from those included or excluded from reviews.

Search strategy

The MEDLINE highly sensitive search strings from the Cochrane Incontinence Review Group for UI and faecal incontinence (FI) were adopted and included all empirical designs (Grant et al. 2006). Search strings were modified to enhance the selectiveness for care homes and older people and exclude studies involving surgical or pharmacological interventions. Copies of the search strategies are available from the lead author.

Inclusion criteria

Empirical studies of the management of incontinence, promotion of continence or maintenance of continence in older people aged 65 years and above in care homes were located. Studies of medical or behavioural approaches with incontinence defined or specified were included (see Table 1).

Table 1
Inclusion criteria for empirical studies

Exclusion criteria

Studies of pharmaceutical or surgical interventions were excluded as the focus was on care practices undertaken by nurses or care assistants in care homes. Non-empirical studies were excluded (see Table 2).

Table 2
Exclusion criteria

Search outcome

There were 167 located references; 6 duplicates, 79 excluded studies (see supporting information Table S2 in the online version of the article in Wiley Online Library) and 82 relevant references – five systematic reviews (all four Cochrane Reviews, Eustice et al. 2000, Ostaszkiewicz et al. 2004a,b;, Wallace et al. 2004; and one associated paper, Ostaszkiewicz et al. 2005) and 76 included references to 60 original studies (37 intervention studies and 23 observational/descriptive studies) (Figure 1).

Quality appraisal

All, titles, abstracts and references identified were checked by two reviewers. Of the 60 original studies, all incorporated quantitative methods with the exception of one that used grounded theory and qualitative data (Robinson 2000). Quality assessments of all studies were undertaken by two reviewers using an 18-item checklist for quantitative studies and a 15-item checklist for qualitative studies. These checklists, used by Shaw et al. (2009, pp. 9–11) and adapted from Downs and Black (1998) and Kmet et al. (2004) were made relevant to this review. The checklist allowed a common approach to the assessment of study quality, strength of evidence and a total score derived. No studies were excluded based on quality appraisal.

Data extraction

A data extraction form was developed, circulated for comment and agreement among co-reviewers. Electronic versions were used independently by three reviewers to extract information. This information was checked by a second reviewer and agreement reached for accuracy for all included studies. Data were extracted for study settings, purpose, populations and samples, methods, main findings and conclusions (Table 3) and synthesized in 2007–2009.

Data synthesis

The studies differed in their aims, methods, outcome measures, patient characteristics and quality. The review adopted a broad approach to capturing relevant empirical studies to encapsulate and describe the extent of work related to management of incontinence in care homes and was not restricted to a narrow focus. Narrative synthesis using techniques from metastudy for primary qualitative research provided summary description for all included studies and allowed contrast and comparison of quantitative and qualitative data (Paterson et al. 2001).

Results

Descriptive observational studies

Twenty three descriptive or observational studies were located, of which 10 studies had UI as the primary focus (Table 3). These studies included cohort, case study or survey design related to UI as the primary outcome either with or without concomitant FI (n = 8; Ouslander 1982, Palmer 1991, Peet 1996, Sgadari 1997, DuBeau 1999, Watson 2003, Jumadilova 2005, Wagg 2005) or economic evaluation of managing UI (n = 2; Ouslander 1984, Schnelle 1988) (Table 3). Studies associated with other conditions or management approaches, with UI not the primary focus are not reported in this study (n = 13).

Dates of publication and data collection of descriptive studies with management of urinary incontinence as primary focus

Included studies spanned the period 1980 to 2005 (Ouslander 1982, 1984, Schnelle 1988, Palmer 1991, Peet 1996, Sgadari 1997, DuBeau 1999, Watson 2003, Jumadilova 2005, Wagg 2005). Four descriptive studies did not include dates of data collection (Ouslander 1982, Schnelle 1988, Sgadari 1997, Wagg 2005).

Countries and settings

Most studies were undertaken in the USA (seven) with two in England (Peet 1996) or England, Wales and Northern Ireland (Wagg 2005), and one international study involving seven countries (Sgadari 1997). The majority of studies (n = 8), where stated, included a total of 542 care homes (ranging from 3 per study to 378 care homes per study). Two studies did not specify how many homes were included (Sgadari 1997, DuBeau 1999). Eight studies with UI as the primary focus are reported followed by the two studies that focused on the economic evaluation of management of UI.

Studies with management of urinary incontinence as primary focus

Seven studies comprised retrospective documentary review at the level of care home and/or residents at one or a number of time points and one study formed part of a national audit (Wagg 2005) (Table 3). Inclusion criteria were specified in all eight studies but varied between the individual studies and were not comparable. Exclusion criteria also varied between the studies and were not comparable and were not specified in two studies (Sgadari 1997, Wagg 2005).

Participants/samples

Seven studies specified diagnostic groups and varied across the studies in relation to UI and FI and comorbidities (Ouslander 1982, Palmer 1991, Sgadari 1997, DuBeau 1999, Watson 2003, Jumadilova 2005, Wagg 2005). Mean age or gender were not included in two studies (Ouslander 1982, Sgadari 1997), although, in the latter study, age ranges were provided and 40% (111,676) of the sample were over 85 years of age, with a majority of the samples women (range 65·9–76·2% across seven countries). Of those studies that included mean age and gender participants had a mean age of 82·5 years (n = 164,235; Palmer 1991, Peet 1996, DuBeau 1999, Watson 2003, Jumadilova 2005, Wagg 2005). Two studies specified ethnic origin with a majority of residents being White (89·2%, Jumadilova 2005; 96%, Watson 2003).

Methods

The main methods involved documentary review and analysis (medical records or case notes) at one time point (Ouslander 1982, Peet 1996, Sgadari 1997, Jumadilova 2005, Wagg 2005) with follow-up review at one (Watson 2003), two (DuBeau 1999) or three time points (Palmer 1991). UI was verified by researchers or individual assessment (Palmer 1991, Peet 1996, Watson 2003) or by the analysis of a cross-sectional database of 6 months or 2 years of newly admitted residents (Jumadilova 2005). All studies involved the collection of quantitative data from documentary evidence, which included data on UI, FI and comorbidities, mental status, functional dependence, activities of living and continence management.

Power calculations or an indication of the sample size required was not specified in seven studies, while Wagg (2005) provided an estimate. Loss to follow-up was included in two studies (Palmer 1991, Watson 2003).

Prevalence and incidence

Seven studies included prevalence of UI with two studies also including incidence (Palmer 1991, Watson 2003). A prevalence estimate was not possible in the national audit (Wagg 2005). The definition of UI was not specified in all studies and varied between those that did (Ouslander 1982, Sgadari 1997, DuBeau 1999, Watson 2003, Jumadilova 2005). Prevalence of UI ranged from 30% to 65% (Sgadari 1997, Jumadilova 2005), FI 22·4% to 55·5% (Sgadari 1997) and both UI and FI from 20·5% to 64% (Ouslander 1982, Sgadari 1997) between the studies and care home populations (Table 3). Prevalence in women was reported as being higher than in men (77·6% of 58,850 that represented a 65% prevalence rate, DuBeau 1999). One study reported that 69% of care home residents had UI most days and, for 39%, it was severe (Peet 1996). Jumadilova (2005) found 30% of residents had some level of UI. Looking at change in prevalence over time Palmer (1991) found 39% with UI at 2 weeks, 37% at 2 months and 44% at 1 year (of whom 90% had dementia). DuBeau (1999) estimated a change in UI for 68% of the sample over 6 months. Change was defined as decline (new or more severe UI), no change or improved. They found 83% were unchanged, 12% declined and 5% improved with a statistically significant association found between UI decline and worsening UI with worse quality of life (QoL; P< 0·00001).

For the two studies that included an estimate of incidence of UI, one reported a rate of new cases over 1 year as 27% with men having a higher incidence of UI than women (9/16 vs. 21/96, P< 0·004). Watson (2003) found 1·9% of newly admitted residents had UI whereas 2·2% of established residents developed new UI over a 3-month period.

Urinary incontinence and associated factors

The studies found UI associated with a number of factors and comorbidities. Ouslander (1982) found people with UI had cognitive impairment, limitations with mobility, skin irritations or urinary tract infection (UTI). They also had one or two related comorbidities, dementia (45%), stroke (28%), Parkinson disease (9%), depression (6%), paraplegia, tumours and bladder cancer (<5%). Peet (1996) reported the majority of people with UI had problems with mobility (85%). UI was significantly associated with having dementia, dependent walking and dependent transfer at 2 weeks (all, P< 0·001; Palmer 1991). UI at 2 weeks and dementia at 2 months were also significantly associated with UI at 1 year (P< 0·05). UI increased significantly over 1 year (P< 0·001). However, age was not associated with incidence or prevalence. Dementia was highly prevalent in new cases of UI (90%). One-year risk factors were calculated using multiple regression analysis, the highest factor being male (68%), presence of UI at 2 weeks, poor behavioural adjustment to the care home at 2 weeks and dementia at 2 months. Patients with these attributes had a cumulative increased risk factor of UI at 122%. Patients with no detectable mental morbidity had the lowest incidence of UI. FI was associated with UI (P< 0·05). Resolution of UI was significantly associated with the ability to ambulate, transfer independently, absence of FI and dementia (P< 0·05; Palmer 1991).

In the study across seven countries (Sgadari 1997), positive associations between age and UI were found but not in Sweden and Iceland. Dependent locomotion was significantly associated with UI in all countries (P< 0·001) and cognitive status, with mild-to-severe impairment associated with UI (P< 0·001). UTI was only associated with UI in four countries (P< 0·001). This study demonstrates that cultural variations should be allowed for and findings between countries cannot be generalized. However, impairment in cognition and mobility are significantly associated with UI and UI is highly prevalent in care home populations.

These findings are supported by DuBeau (1999) who found a statistically significant association between new or worsening/decline in UI and lower QoL, and improving UI with better QoL (P< 0·001). There was a statistically significant association between lower QoL and UI in people with moderate activity of daily living (ADL) impairment regardless of cognitive status (P< 0·001). Multivariate analysis demonstrated UI was associated with a decline in QoL (OR = 1·46, 95% CI: 1·36–1·57), second to the impact of cognitive decline (OR = 2·06, 95% CI: 1·93–2·21) and functional decline (OR = 1·78, 95% CI: 1·66–1·90) on worsening QoL. Jumadilova et al. (2005) found mean age and length of stay increased with severity of UI (P< 0·001).Only four studies included assurance of the reliability of the data collected in their report of methods (Palmer 1991, DuBeau 1999, Watson 2003, Wagg 2005).

Results related to management of incontinence

Assessment and documentation

Both Ouslander (1982) and Watson (2003) reported that <15% of residents had their incontinence recorded in care home records or efforts made to evaluate it. Watson (2003) found only 15% of cases had their UI assessed by their clinician (doctor or nurse) and only one case had completely documented UI symptoms for the presence or absence of stress, urge or overflow. Documentation for the presence or absence of urge UI was most common (15%), but only for the minority. Frequency of episodes of UI (20%) and timing (2%) were also only recorded for a minority. Frequency volume charts of UI were non-existent, although fluid input and output records for two consecutive days were available for nearly half of residents (47%). Clinical examinations were undertaken for a minority. 81% had a reversible cause of UI at onset but only 34% had this addressed and 3% received treatment (n = 6).

More recent data from a national audit in care homes in England, Wales and Northern Ireland (Wagg 2005) that reviewed the management of UI found 74% of care homes stated integrated continence services were available locally, with 50% stating there was a lead person available. All care homes routinely asked residents about bladder problems but did not necessarily follow through with an assessment. A documented continence history was available for 70% of residents. 89% of residents had a documented care plan, 82% were reviewed in the last 6 months, 41% had a documented discussion about cause of UI and treatment with 34% having a bladder diary or frequency volume chart. A clear type of UI was recorded for 40% of residents, and a specific treatment plan for the majority (82%). The audit also investigated the management of FI or mixed FI and UI as a separate entity Documented treatment plans for 76% of residents reviewed were available, with treatment goals recorded for 54%, advice on general health (12%), advice on lifestyle (9%), FI chart (33%) and documented history available (50%; range 45–63%).

Policies

Peet (1996) found that most care homes had policies for managing incontinence (use of pads 87%, use of continence sheets 62%, personalized bathing policy 51%, use of appliances or catheters 41%, with 21% having a policy on intake of incontinent residents who were precluded from admission) and the promotion of continence using a variety of strategies (day time toileting 83%, use of aids – 68%, night toileting 52%, use of toilet signs 49% with only 38% restricting or adjusting fluids.

The national audit that investigated the management of UI and FI or mixed FI and UI as a separate entity (Wagg 2005) found 96% of care homes had access to a continence specialist (median 1·0), 100% of care homes routinely asked about bowel problems, with privacy and dignity reported as being maintained by 100% of care homes and having a written policy (93%), integrated care pathway (12%) or written protocol for assessment (88%). Structured programmes on incontinence for staff were available in 63% of homes and included basic assessment (65%), specialist continence assessment conducted by practitioner (41%), areas for assessment and treatment to maintain privacy and dignity (100%), with bladder and bowel care subject to regular audit (64%) and evidence based information freely available to patients and carers (85%). Management plans were available in 76% of care homes. Eighty-six per cent of care homes stated products were supplied on clinical need and not cost and 76% sought patients’ views on choice of products. There was evidence of rationing in 76% of care homes and the median supply of products per day was four.

Management techniques

Peet (1996) reported on aids used, continence promotion and aspects of management requiring change. Continence promotion techniques for 57% of residents included [toileting 46%, fluid adjustment 16%, bladder training (BT) 6%]. More than half of residents received one or more techniques for the management of UI or promotion of continence (57%), although pelvic floor muscle exercises had not been undertaken with any residents. Based on the assessment of individual cases (n = 96), it was judged that their management of UI should be changed for some residents in relation to use of pads (25%), drug therapy (15%) appliances (9%), investigations (47%), BT (31%), toileting (27%), use of continence aids (12%) or fluid intake (9%). Fifty-seven per cent of homes (n = 39) requested more support from a continence service.

Care practices for managing UI in individual cases varied across countries with the testing of incontinent residents for UTI ranging from 48% in France to 11% Italy and Sweden and faecal impaction ranging from 0·5% in Sweden to 27·3% in France. Use of scheduled toileting ranged from 50·7% in Iceland to 5·6% in Italy and the use of pads for individual management ranged from 71·6% in the USA to 92·9% in Iceland. Use of pads was the most common management technique used for managing UI in care homes. Having no toileting programmes or use of the toilet for people with UI ranged from 22·8% in the USA to 2·6% in Italy and 52·7% in Japan to 4·4% in France. Use of pads was the most common management strategy and there was marked variation in the use of scheduled toileting programmes, and it was not apparent what these involved (Sgadari 1997).

A more recent study showed that expectations of families with regard to UI management were recorded in only 2% of instances. They also found appropriateness of treatment against the Agency for Health Research and Quality (AHRQ) guideline (Fantl 1996) could not be evaluated in all cases because of a lack of an UI diagnosis (Watson 2003). In relation to UI management, a majority 99% used absorbent products, and 28% had new UI management but without cure as the aim. This involved routine scheduled toileting; timed voiding (80%), habit retraining (14%) or prompted voiding (15%). Overall, 83% had some toileting programme. It is not clear if BT was used as part of scheduled toileting or just timed voiding as it was not mentioned, although BT may not be suitable due to the high prevalence of cognitive impairment in residents. Indwelling catheters (IC)(2%), intermittent catheterization (2%), external sheaths for men (5%) and pessaries for women (2%) were used by a minority. All use of catheters was justified.

The AHRQ UI guideline (Fantl et al. 1996) had 90 standards that could be applied and each case was assessed with the number of standards applicable to them. Compliance ranged from 0% to 45% with a mean compliance of 20% and a median of 21%. After 12 weeks, 6% of residents were continent; 4% because of treatment of a reversible cause (mobility limitation, UTI, precipitating medication) and 2% because of a toileting programme (scheduled toileting, prompted voiding). Watson (2003) concluded the guideline had been underused but its use was feasible. The AHRQ guideline is generic and not specific to care homes. Staff awareness and familiarity with the guideline was identified as a barrier.

Jumadilova (2005) found only 8% of residents with UI were treated with drugs, with 8·7% of those with severe incontinence receiving drugs. A statistically significant association was found with more severe UI and the use of BT (P< 0·001), incontinence pads/briefs (P< 0·001) or scheduled toileting (P< 0·001).

The audit of care homes found documented treatment plans for 76% of residents were available. They included: treatment goals recorded (54%), advice on general health (12%) or lifestyle (9%), an FI chart (33%), bowel training/regimes techniques (13%), improved mobility (17%), improved quality of access to toilet facilities (14%), pelvic floor muscle exercises (1%), drug therapy (27%), medications review (29%), surgery (2%), use of toileting schedules (52%), treatment of comorbidities (8%), other interventions or none of these documented (15%) (Wagg 2005). The audit findings indicate that practice in care homes has developed as the studies from the 1980s, early 1990s and that the majority of residents had documented care plans, although less than half and, in some cases, a small minority active management of UI and FI.

In all of the above studies, no economic data regarding the management of UI and outcomes were included. The quality ratings of the studies ranged from 54% to 100%, with two studies achieving the maximum score (Jumadilova 2005, Wagg 2005).

Details of research funding were included in a minority of studies (Palmer 1991, Watson 2003, Jumadilova 2005, Wagg 2005).

Studies with an economic evaluation of managing urinary incontinence

The focus of two studies was economic evaluation of managing incontinence based on observational and descriptive data (Ouslander 1984, Schnelle 1988). Estimates of costs of management were calculated from survey data from staff questionnaires from 16 care homes (Ouslander 1984, including data from seven nursing homes from a previous study, Ouslander 1982). Data were based on patients with UI, with or without FI, but sample size and ages were not included nor the response rate for staff questionnaires returned which the data were based on. Schnelle (1988) based estimates on 231 incontinent and continent residents who consented (92%, n = 252) from three nursing homes (extending data from Ouslander 1982). All residents were stated to be aged 65 years and above but details on age, gender, and ethnicity were not reported in either study and no exclusion criteria were specified. Only continence status was stated with no other diagnostic conditions or comorbidities reported.

Methods

Cost estimates were derived from staff questionnaire surveys, medical supply companies and a laundry company for incontinence products (Ouslander 1984) and by direct observation of care for toileting and cleaning (Schnelle 1988). Models of costs were developed based on supplies, laundry and labour (first-level costs) and complications (second-level costs related to skin or treatment of UTI in the home or hospital) (Ouslander 1984) and staff time and laundry (Schnelle 1988). Dates of data collection were not specified, although Schnelle (1988) obtained data over 9 months using a 21-item toilet assessment inventory (with 93% agreement) while the Ouslander's (1984) study was from one time point. No indication of sample size or power calculation were included. Quality ratings were 36% and 42%.

Prevalence and incidence

Prevalence of UI was not reported by Ouslander (1984), although Schnelle (1988) stated 51% of residents had UI and 49% were continent in the nursing homes studied.

Outcomes for management of incontinence

Ouslander (1984) reported a trend for lowest costs being incurred for residents managed with indwelling urinary catheters (range: $2·90 minimum of 1 bed change per day–$5·11 maximum of 5 bed changes per day) vs. the highest with disposable bed pads (range $6·91 minimum 3 bed changes per day –$11·09 maximum bed changes per day) based on first-order costs. If second-order costs were estimated based on the incidence of complications, yearly costs per patient with use of a catheter were $2888 compared to the cost of a patient without a catheter from $2072 to $4532. They concluded the use of indwelling catheters for the management of UI was not justified.

Schnelle (1988) reported 78% of residents with UI were dependent for toileting vs. 7% who were continent. Only 9% of residents with UI were able to toilet independently compared to 82% who were continent (P< 0·0001). Based on observation of 116 cleaning and 132 toileting care episodes, the total time to toilet a resident was 2·42 minutes more than the cleaning time (7·97 vs. 5·55 minutes, P< 0·004) due to the additional time of travel and assistance. They concluded that it costs more to maintain continence in a dependent resident than it takes to manage incontinence, whereas Ouslander (1984) concluded that active evaluation and treatment of UI could provide cost savings and improve well-being of patients and carers. A comprehensive economic evaluation of maintaining continence and managing incontinence in care home populations is warranted. The quality rating of both studies was low, 36% and 42%. Neither study specified their source of funding.

Discussion

This review found that descriptive studies for the management of incontinence and promotion of continence in care homes involved mainly women with a mean age above 80 years, which reflects prevalence of the condition and care home populations. The prevalence of UI was higher than FI with more women affected than men, which is in keeping with findings of community populations with the range of prevalence higher in these institutional settings ((McGrother et al. 2003, Fonda et al. 2005). No studies in the review were aimed at maintaining continence in residents in care homes.

Methodological issues and limitations

The studies were restricted to only those published in English. They comprised mainly documentary analysis and review and may have limited reliability and validity. Only three studies followed up residents over time (Palmer 1991, Peet 1996, Watson 2003), with Palmer (1991) following up to 1 year. Quantitative data were collected with only four studies reporting on the reliability of data (Palmer 1991, DuBeau 1999, Watson 2003, Wagg 2005). Power calculations to justify sample sizes and loss to follow-up did not generally feature. The overall quality of studies was variable with the economic evaluations scoring the lowest total scores, which may reflect the focus of the reports and limited methodological information included.

The range of data collected included UI and FI status, mental status, functional abilities, ADLs and comorbidity. The severity of incontinence was not routinely recorded. The majority of residents with UI had problems with mobility and/or dementia and were found to be significant (Palmer 1991) with deterioration in UI significantly affecting QoL (DuBeau 1999), which indicates interventions aimed at improving or preventing incontinence are warranted. The one international study reported variations across care home populations for prevalence of incontinence and approaches to management between countries (Sgadari 1997), which reflect organizational, cultural, management, policy and practice differences in this care sector within countries making comparison difficult. Studies targeted in care homes within countries are warranted.

Studies from the 1980s and 1990s generally found that incontinence had not been documented or assessed with the exception of the study reported in 2003 (Watson 2003) who compared documentation and management with the AHRQ guidelines (Fantl et al. 1996) and who also reported only a minority of residents having their incontinence documented or assessed. A more recent national audit of care homes, however, reported that a majority of 70% did have a history of incontinence recorded, with 89% having a documented care plan and 82% or residents having been reviewed in the previous 6 months (Wagg 2005). These changes in practice reflect recognition of the need to manage incontinence and promote continence, available research evidence as well as the development and implementation of guidelines within countries (Fantl et al. 1996, Button et al. 1998, NICE 2006, 2007, Abrams et al. 2009), although none were specifically developed for care home populations.

Policies and management

Use of incontinence pads and toileting were the most prevalent forms of management and feature of documented policies. The detail on toileting programmes used was not explicitly specified but stated to include BT, scheduled toileting and prompted voiding. As has been previously reported, operational definitions and content of toileting programmes have not been included in studies and their theoretical basis requires revisiting (Roe et al. 2007a,b;) so they reflect contemporary developments in behavioural techniques and interventions. Habit retraining, timed and prompted voiding are common toileting practices used in care home populations for residents with cognitive or physical impairments, with limited evidence on effectiveness for timed voiding (Eustice et al. 2000, Ostaszkiewicz et al. 2004a,b;). Recent studies have included prompted voiding with physical exercise for residents with some evidence of effectiveness (Schnelle et al. 2002) and reflect the combined interventions and approaches being adopted for managing incontinence (Roe et al. 2007a). Other forms of management, such as, pelvic floor muscle exercises, drugs, catheters or penile sheaths featured less frequently. Wagg (2005) found treatment goals were documented for 54% of residents with 76% of homes reporting that they would involve residents in choice of incontinence products. However, only 2% of family members were reported as being involved in decisions on the management of incontinence by Watson (2003). No studies reported involving residents in decision-making regarding their management goals.

Two studies assessed whether the current management of incontinence should be changed and identified this was the case for a minority of residents (Peet 1996, Watson 2003). Watson (2003) concluded that the AHRQ guideline (Fantl et al. 1996) had been under utilized in care homes but its use was feasible. These studies spanning the last 30 years demonstrate that there are improvements in the implementation of care for managing incontinence in care home residents. However, there is a lack of longitudinal studies incorporating documentary review and observed practice for these populations and further research is warranted to determine outcomes and improvements in continence status. Studies targeted at maintaining continence in residents who are continent should also be undertaken.

Economic evaluation

Only two studies gave an economic evaluation (Ouslander 1984, Schnelle 1988). Costs of using indwelling catheters were more expensive than using incontinence pads (Ouslander 1984), whereas toileting residents incurred more costs due to the increased time required than changing and cleaning them (Schnelle 1988). Schnelle (1988) concluded that it costs more to maintain continence in dependent residents than managing incontinence. Economic evaluations of maintaining continence and different interventions for managing incontinence are justified.

Conclusion

Combined evidence suggests that conservative approaches for managing incontinence and promoting continence involving pads and toileting are most frequently used for residents in care homes. Improvements in documenting practice and assessment of incontinence have been identified over the last three decades, although there are variations between and within countries. Involving residents or family members in decisions for managing incontinence is poorly reported and should be more widely practised. Studies on maintaining continence and identification of components of toileting programmes that make them successful incorporating full economic evaluation are warranted.

What is already known about this topic

  • Incontinence is a prevalent condition among older people living in care homes with reported range of prevalence variable across studies and populations.
  • Incontinence incurs personal and institutional costs in terms of quality of life, staff time, laundry, use of aids and appliances.
  • Research on the management of incontinence in care home populations has been undertaken predominantly in the USA by designated research teams and findings may not be transferable to other populations or settings where the organization, staffing and delivery of care may vary.

What this paper adds

  • There is emerging evidence that the management of incontinence and promotion of continence is an increasing feature of practice within care homes reflected by the increased availability of policies and documented care.
  • Use of incontinence pads and toileting regimens are the most common forms of care for older people with incontinence in care home populations.
  • The evidence base, theories underpinning toileting practices or their form, frequency and content are unclear from the studies reviewed but are stated to comprise bladder training, scheduled or prompted voiding.

Implications for practice and/or policy

  • Involving residents of care homes or family members in decisions for managing incontinence should be more widely practised.
  • Studies on maintaining continence and identification of components of toileting programmes that make them successful along with economic evaluation are warranted.
