Introduction:

Urinary incontinence (UI), defined as the involuntary leakage of urine, represents a widespread and often distressing condition among older adults residing in nursing homes. Its prevalence in this demographic is alarmingly high, with estimates ranging from 43% to 79%, significantly surpassing rates observed in community-dwelling older individuals. Beyond the immediate discomfort and embarrassment for affected individuals, UI carries substantial implications for their overall well-being and quality of life. It contributes to a heightened risk of urinary tract infections, increases the likelihood of falls, and can exacerbate or even precipitate depression. The persistent challenges posed by UI also impose a substantial burden on caregivers and healthcare systems, underscoring the urgent need for more effective and humane management strategies.

Traditional continence care in nursing homes often relies on scheduled "check and change" routines, where caregivers manually assess and replace absorbent pads. While seemingly straightforward, this approach is fraught with inefficiencies and potential compromises to resident dignity. Caregivers must frequently check pad saturation, a process that can be intrusive and labor-intensive. Premature pad changes lead to wasted resources, while delayed changes risk skin breakdown, leakage, and discomfort for the resident. The inherent challenges of this manual system are further amplified by the increasing prevalence of cognitive and physical impairments among nursing home residents and the pervasive issue of staffing shortages. The imperative to enhance continence care delivery—moving from an institution-centered to a person-centered model—has driven interest in innovative solutions. Digital health technologies, specifically urine saturation sensors, have emerged as a promising avenue. These devices aim to provide real-time data on pad saturation, enabling more timely and appropriate interventions. However, despite the proliferation of such devices, robust comparative clinical trials evaluating their efficacy and safety in real-world nursing home settings have been notably scarce. This study endeavors to fill that void, rigorously examining the TENA SmartCare Change Indicator's impact on care efficiency and resident outcomes.

The Overarching Challenge of Incontinence in Long-Term Care

Urinary incontinence is a multifaceted health issue, particularly challenging within the context of nursing homes. The condition is rarely isolated, often intertwining with comorbidities, cognitive decline, physical limitations, and polypharmacy, which collectively complicate its management. For many residents, UI is not curable, necessitating comprehensive management strategies focused on mitigating its impact. Absorbent products, such as pads, coupled with structured toileting schedules, serve as primary containment methods. However, the practical application of these strategies in a busy nursing home environment often falls short of optimal standards.

The "check and change" routine, a cornerstone of current continence care, mandates frequent manual assessments of pad wetness. This involves caregivers physically checking the pad, an approach that can be undignified for residents and time-consuming for staff. Such manual checks, performed multiple times daily, are a constant source of potential worry for caregivers, who strive to ensure resident comfort while managing a heavy workload. The subjective nature of these checks—relying on visual inspection, touch, or even smell—can lead to inconsistencies, resulting in pads being changed too early (leading to waste) or too late (causing discomfort, skin irritation, and leakage onto clothing and bedding). These inefficiencies not only strain resources but also negatively affect resident dignity and privacy.

The financial and environmental implications of current continence care practices are also substantial. Millions of absorbent pads are discarded daily, contributing to significant waste and associated disposal costs. Optimizing pad usage through more precise saturation detection could yield considerable economic and ecological benefits. Beyond the tangible costs, the intangible human cost—diminished quality of life for residents and increased workload and stress for caregivers—underscores the need for transformative solutions. Against this backdrop, digital health technologies offer a beacon of hope, promising to introduce precision, efficiency, and a more person-centered approach to continence care.

Pioneering Smart Solutions: The TENA SmartCare Change Indicator

The TENA SmartCare Change Indicator is a Class I medical device designed to revolutionize continence management for nursing home residents who are unable to consistently communicate their toileting needs or require assistance with pad changes. This innovative digital health technology system comprises two core components: a reusable electronic sensor and a dedicated smartphone application. The sensor, discreetly placed on the exterior of the absorbent pad, continuously monitors and estimates the degree of urine saturation. This real-time data is then wirelessly transmitted to the smartphone application, which displays the saturation level and, crucially, notifies caregivers when a pre-set saturation threshold is reached—in this study, set at 70%.

The operational workflow with the Change Indicator is designed to be seamless. Upon identifying eligible residents and obtaining consent, nursing home staff (caregivers) undergo comprehensive training on the device's setup, usage, and troubleshooting. Each care unit designates a "superuser" to provide on-site support, ensuring smooth integration into daily routines. Following an initial four-week familiarization period, baseline data are meticulously collected, paving the way for a six-week device utilization phase. During this intervention period, caregivers rely on the Change Indicator's notifications to guide pad changes, shifting from a rigid schedule to a more responsive, needs-based approach. In contrast, control groups continue with their established manual check and change regimens.

This technology offers several theoretical advantages. By providing objective, real-time data on pad saturation, it eliminates the guesswork inherent in manual checks, potentially reducing unnecessary interruptions for residents. This precision could lead to more optimal pad utilization, minimizing waste from premature changes and preventing discomfort and skin issues from delayed changes. Furthermore, by streamlining the assessment process, the device could free up valuable caregiver time, allowing them to focus on other essential care tasks and potentially alleviating some of the chronic staffing pressures faced by nursing homes. The study's design aimed to robustly evaluate these potential benefits, focusing on tangible improvements in care efficiency, resident well-being, and caregiver workload.

Evaluating Efficacy and Safety: A Rigorous Trial Design

The study employed a prospective, open-label, cluster randomized controlled trial design, spanning six weeks in nursing homes across Edmonton, Alberta, Canada, and the Lower Rhine Region, Germany. This design allowed for the comparison of care delivery with the Change Indicator against usual care practices, while accounting for the inherent variability across different care units. Nursing homes were selected based on specific criteria, including being registered facilities, having a high percentage of residents aged 65 or older, and either currently using TENA pads or agreeing to do so for the study duration.

Resident inclusion criteria were carefully defined to target individuals most likely to benefit from the device: those over 65 years of age with a permanent stay, unable to consistently communicate their toileting needs, and requiring assistance with pad changes as part of a routine check and change regimen. Exclusion criteria were equally strict, encompassing conditions such as frequent fecal incontinence, severe pre-existing skin problems, presence of indwelling or external urinary catheters, anuria, or participation in other investigational studies. This meticulous selection process aimed to ensure the study population was representative of those who would genuinely benefit from such an intervention in a real-world setting, while also safeguarding participant well-being. Caregivers provided informed consent for the collection of their specific measures, underscoring the comprehensive nature of the study's ethical considerations. Ethical approvals were secured from relevant health research ethics boards in both Canada and Germany, and the trial adhered to stringent international medical device regulations and ethical declarations.

The primary outcomes of the study were twofold:

1. Care Efficiency Score: This compound measure quantified the weighted sum of various continence care activities, including pad checks, pad changes, toilet visits, clothing changes, and linen changes due to leakages, averaged per daily score. The goal was to assess whether the device could lead to a statistically significant improvement (reduction) in the time spent on these tasks.
2. Change in Skin Health: Measured using a modified version of the validated Incontinence-Associated Dermatitis and its Severity Instrument, this aimed to determine if device use maintained or improved skin integrity, with a non-inferiority margin of 0.5 grades. The device needed to demonstrate superiority in care efficiency while being non-inferior in terms of skin health.

Secondary outcomes encompassed a broad range of measures related to both residents and caregivers. Resident-related outcomes included the daily number of pad checks, pad changes, toilet visits, clothing changes, linen changes, time spent in a saturated pad, and crucially, the number of sleep interruptions due to continence care. Resident quality of life and responsive behavior scores were also assessed. For caregivers, the study evaluated work engagement and "organizational headroom," a metric reflecting the perceived availability of time for other tasks. This holistic approach aimed to capture the multifaceted impact of the Change Indicator on both the recipients and providers of care, painting a comprehensive picture of its real-world utility and safety profile.

The Study's Demographic and Operational Landscape

Fourteen nursing home sites, equally distributed between Canada and Germany, were successfully recruited for the trial. Nine of these sites were already operating under standard check and change regimens, providing a realistic comparative context. The study enrolled 108 residents, with 53 assigned to the intervention group utilizing the Change Indicator and 49 to the usual care group. The median age of residents was 87 years, ranging from 59 to 101, highlighting the focus on an elderly population with diverse needs. The majority (78.5%) of participants were female, reflecting the higher prevalence of UI in women.

A significant finding regarding the resident population was the high prevalence of cognitive impairment. Among residents where the Mini-Mental State Examination (MMSE) could be reliably assessed, 37% (38 out of 51) exhibited severe cognitive impairment. Notably, there was a statistically significant difference between the groups in terms of MMSE scores: 12% of residents in the usual care group showed no signs of cognitive impairment, a category entirely absent from the intervention group. This suggests that the intervention group, by chance, comprised a slightly more cognitively impaired population, which could potentially influence outcomes related to communication and self-care. At baseline, a substantial proportion of residents in both groups—87% in the intervention group and 74% in the usual care group—were categorized as being in the highest dependency groups, indicating significant reliance on caregivers for daily activities.

Caregiver participation included 83 individuals, with 52 in the intervention group and 31 in the usual care group. While the study aimed to recruit six frontline caregivers per care unit, this target was not consistently met across all sites, which could impact the generalizability of caregiver-specific findings. Despite some challenges in recruitment and adherence to the precise number of participants per cluster, a post-hoc power analysis indicated that the study maintained a high power of 99%, primarily due to lower-than-anticipated data variation. This robust statistical power suggests that the observed outcomes, where significant, are unlikely to be due to chance, strengthening the reliability of the findings. The demographic profile of the participants underscores the relevance of this study to the complex realities of long-term care, where residents often present with multiple comorbidities and varying degrees of cognitive and physical dependency.

Dissecting the Outcomes: Efficiency, Skin Health, and Resident Well-being

The trial’s results presented a nuanced picture of the TENA SmartCare Change Indicator’s impact. The co-primary outcomes, care efficiency and skin health, revealed distinct patterns. Skin health scores remained consistently low (indicating good skin health) throughout the study in both groups, and there was no statistically significant difference in the change in skin health between the intervention and usual care groups. The non-inferiority test for skin health achieved statistical significance, confirming that the device did not negatively impact skin integrity. This is a crucial finding, as concerns about potential skin deterioration due to less frequent manual checks are often raised in the context of automated continence care solutions.

Regarding care efficiency, the intervention group experienced a reduction of 30 minutes per day in time spent on continence care activities. While this represents a substantial 31% reduction, it did not reach statistical significance when compared directly to the usual care group. This unexpected outcome was largely attributed to a simultaneous, albeit slightly smaller, improvement of 16 minutes per day in the usual care clusters, particularly in the German arm of the study. Researchers suggested that the mere presence of the study, and the heightened awareness it brought to continence care, might have spurred improvements in practices across all participating units, regardless of their assignment to the intervention or control arm. This phenomenon, often termed the "Hawthorne effect," where individuals modify their behavior in response to being observed, highlights a potential unintended positive consequence of engaging in research within healthcare settings.

Despite the lack of statistical significance in the primary care efficiency outcome, several secondary outcomes demonstrated notable improvements. The most significant of these was a statistically significant reduction in the mean daily number of sleep interruptions for residents in the intervention group, decreasing by an average of 0.9 interruptions per night (p = 0.018). This finding is particularly valuable, as disrupted sleep can severely impact the health and well-being of older adults, contributing to cognitive decline, fatigue, and behavioral changes. Fewer sleep interruptions suggest that residents using the Change Indicator experienced less disturbance from continence care, potentially leading to improved rest and overall quality of life.

Another compelling secondary outcome was the statistically significant reduction in the total absorbency of pads used per 24 hours in the device use group compared to the usual care group (p = 0.034). This suggests that the Change Indicator facilitated a more efficient and perhaps personalized use of absorbent products. By signaling the optimal time for changes, the device prevented the premature disposal of underutilized pads, thereby reducing overall pad consumption. This outcome has significant implications for cost savings in nursing homes, as continence products represent a substantial expenditure, and also contributes to environmental benefits by reducing waste.

However, other process measures, such as the daily number of pad checks, pad changes, toilet visits, clothing changes, and linen changes, did not show statistically significant differences between groups. Similarly, there were no significant changes in resident quality of life (as measured by EQ-5D VAS and QoL-AD scores) or responsive behavior scores. From the caregiver perspective, there was no observed difference in work engagement scores or in organizational headroom metrics, such as the perception of adequate staff or tasks being rushed or left undone. This indicates that while the device improved specific aspects of care, its broader impact on staff workload or perceived organizational efficiency was not statistically evident in this short-term trial.

Safety data for the device were largely positive, with only one adverse event—a deterioration in skin health—documented as definitely related to device use. This isolated incident underscores the generally safe profile of the Change Indicator. A total of 18 device deficiencies were reported, primarily related to sensor issues rather than the reusable adhesive strip, and an upgrade to the device during the study period addressed some of these reliability concerns. The low incidence of device-related adverse events and the lack of serious adverse device events are reassuring, suggesting that smart continence care technologies can be safely integrated into nursing home environments.

Interpreting the Findings: Clinical Relevance and Future Directions

The trial's primary outcome, a compound score representing the process of care efficiency, did not reach statistical significance despite a notable reduction in time spent on continence care in the intervention group. This raises important questions about how clinical benefit is defined and measured. The discussion highlights a crucial point in health technology assessment: whether measured "efficiency" truly translates into "quality" that is meaningful to residents and caregivers. While the 30-minute daily reduction in continence care time is substantial, its failure to achieve statistical significance against the control group, which also saw improvements, complicates a straightforward interpretation of superiority. This phenomenon could be attributed to increased awareness and enhanced focus on continence care in both arms of the study, driven by the research presence. This suggests that simply drawing attention to continence care processes, independent of specific technological interventions, might itself lead to improved outcomes.

Nevertheless, the statistically significant reductions in total pad absorbency and, critically, in the number of sleep interruptions for residents using the device, represent valuable and clinically relevant outcomes. Reduced pad usage not only carries economic benefits through lower product costs and disposal fees but also suggests a more precise, needs-based approach to care, moving away from potentially wasteful scheduled changes. The decrease in nighttime disturbances for residents is perhaps the most compelling direct benefit. For older adults, particularly those with cognitive impairments, uninterrupted sleep is vital for maintaining physical and mental health, reducing agitation, and improving overall quality of life. Even if overall care efficiency, as defined by a compound score, did not reach statistical significance, these specific, tangible improvements directly impact resident well-being.

The study’s strengths include its randomized, comparative design, which lends confidence to its findings. The high statistical power achieved, despite some recruitment challenges, further reinforces the reliability of the significant results. However, certain limitations warrant consideration. The short six-week intervention period may not have been sufficient to capture long-term effects or to fully overcome initial implementation hurdles. The varying care routines across different units and the challenges in caregiver recruitment and retention might have introduced some heterogeneity. Furthermore, the turnover of staff and reliance on casual personnel could have influenced the consistency of data recording, potentially underestimating the device's full impact.

The discussion emphasizes the need for a person-centered approach to continence care, where technology serves as an enabler rather than a replacement for human interaction. While the device might lead to fewer direct "checks," the absence of a deterioration in resident quality of life suggests that these interactions, when they occur, are more meaningful and necessary. The study also offers valuable insights for future research and product development in digital health technology. The problems encountered with the reusable adhesive strip and sensors point to areas for technological refinement.

Ultimately, this study provides important evidence supporting the utility of smart continence care solutions. It suggests that while the broad goal of "care efficiency" might be complex to measure and prove statistically, these devices can deliver concrete benefits, such as reduced pad consumption and, most importantly, improved sleep quality for vulnerable nursing home residents. A longer-term implementation and efficacy study, ideally in diverse care settings including home care, is warranted to further investigate and confirm the full spectrum of impacts and benefits of such innovative technologies. Such studies would also benefit from a more detailed qualitative assessment to understand the lived experiences of residents and caregivers, ensuring that technological advancements truly align with person-centered care goals.

FAQ:

Q1: What is urinary incontinence (UI) and why is it particularly challenging in nursing homes? A1: Urinary incontinence is the involuntary leakage of urine. It is highly prevalent in nursing home residents (43-79%) due to a combination of factors, including advanced age, multiple comorbidities, physical and cognitive impairments, and medication effects. It is challenging because many residents cannot consistently communicate their toileting needs, leading to reliance on labor-intensive and often undignified "check and change" routines by caregivers. UI also increases risks of infections, falls, depression, and impacts residents' dignity and quality of life.

Q2: What is the TENA SmartCare Change Indicator and how does it work? A2: The TENA SmartCare Change Indicator is a digital health technology device designed to improve continence care. It consists of a reusable electronic sensor placed on the outside of an absorbent pad and a smartphone application. The sensor estimates the urine saturation level in the pad and transmits this data to the application, which then notifies caregivers when the pad reaches a pre-set saturation level (e.g., 70%), indicating it's time for a change. This shifts care from scheduled changes to needs-based intervention.

Q3: What were the main objectives of this study? A3: The study aimed to examine the efficacy and safety of the TENA SmartCare Change Indicator in older nursing home residents with UI. The co-primary objectives were to assess changes in "care efficiency" (a compound score of care activities like checks, changes, toilet visits, and leakage-related cleanups) and changes in resident skin health. Secondary objectives included evaluating impacts on resident sleep quality, pad usage, quality of life, caregiver work engagement, and organizational efficiency.

Q4: Did the TENA SmartCare Change Indicator significantly improve care efficiency? A4: While the intervention group using the device showed a substantial reduction of 30 minutes per day in time spent on continence care (a 31% reduction), this improvement did not reach statistical significance when directly compared to the usual care group. This was largely because the usual care group also experienced a 16-minute per day improvement, possibly due to increased awareness of continence care driven by the study's presence.

Q5: What was the impact of the device on resident skin health? A5: The study found no statistically significant deterioration in skin health for residents using the Change Indicator. Skin health scores remained good throughout the study in both groups, and the device met the non-inferiority criterion for skin health, indicating it did not negatively impact skin integrity.

Q6: What were the most significant positive outcomes observed with the device? A6: Two particularly valuable outcomes were statistically significant: 1. Reduced Sleep Interruptions: Residents using the device experienced a significant reduction of 0.9 sleep interruptions per night due to continence care. This suggests improved rest and potentially better overall well-being for residents. 2. Reduced Pad Absorbency: The total absorbency of pads used per 24 hours was statistically significantly reduced in the device group. This implies more efficient and personalized pad utilization, leading to potential cost savings and environmental benefits.

Q7: Were there any adverse events or technical issues with the device? A7: Overall, the safety data for the device were positive. One adverse event of skin deterioration was deemed definitely related to device use. There were 18 reported device deficiencies, mostly related to sensor issues, but no serious adverse device events occurred. An upgrade to the device during the study helped address some reliability concerns.

Q8: What are the limitations of this study and what are the recommendations for future research? A8: Limitations include a shorter intervention period (six weeks) which might not capture long-term effects, challenges in recruiting the target number of caregivers per unit, and potential "Hawthorne effects" where general study participation improved care in both groups. Future research should involve longer-term implementation and efficacy studies in diverse settings (nursing homes and home care) to confirm broader impacts. Qualitative research is also recommended to explore the nuances of "care quality" from the perspective of both residents and caregivers.
