Abstract

We investigated the feasibility of using a "wash-and-dry" toilet in the nursing home. We used a controlled comparison baseline-versus-treatment design with 22 female nursing home residents aged 75 and older living in a 562-bed, not-for-profit nursing home facility in Maryland. The Luscence Luxury Lavage wash-and-dry toilet-bidet system was installed in the bathrooms of the experimental group. Measurements included staff and resident toilet experiences and toilet reaction questionnaires, utilization logs, Minimum Data Set information, Mini-Mental State Examination scores, and urine cultures. About half of the residents and staff members reported the toilet to have a positive effect on toileting. We saw a positive trend in resident affect for the experimental group that was not apparent for the comparison group. Nursing staff reported that the toilet functions did clean the residents, but that cleaning was not complete. Bacterial content of urine decreased in the experimental group and increased in the comparison group during the trial. Toilet installation was more complex than anticipated. These results show that a wash-and-dry toilet shows promise for improved resident comfort in toileting and cleanliness, although further research is needed to verify the findings. Improved toilet design, design of nursing homes, and design of care activities would all improve the utility of these toilets in the nursing home population.

Translating clinical research into practice: a randomized controlled trial of exercise and incontinence care with nursing home residents.

Charles Simmons, John Schnelle, Joseph Ouslander … (2002)

To examine clinical outcomes and describe the staffing requirements of an incontinence and exercise intervention. Randomized controlled trial with blinded assessments of outcomes at three points over 8 months. Four nursing homes. Two hundred fifty-six incontinent residents. Research staff provided the intervention, which integrated incontinence care and exercise every 2 hours from 8:00 a.m. to 4:00 p.m. 5 days a week. Average and maximum distance walked or wheeled, level of assistance required to stand, maximum pounds lifted by arms, fecal and urinary incontinence frequency, and time required to implement intervention. Intervention residents maintained or improved performance whereas the control group's performance declined on 14 of 15 outcome measures. Repeated measures analysis of variance group-by-time significance levels ranged from P <.0001 to.05. The mean time required to implement the intervention each time care was provided was 20.7 +/- 7.2 minutes. We estimate that a work assignment of approximately five residents to one aide would be necessary to provide this intervention. The incontinence care and exercise intervention resulted in significant improvement for most residents, and most who could be reliably interviewed expressed a preference for such care. Fundamental changes in the staffing of most nursing homes will be necessary to translate efficacious clinical interventions into everyday practice.

The MDS Cognition Scale: a valid instrument for identifying and staging nursing home residents with dementia using the minimum data set.

S L Hartmaier, P D Sloane, H Guess … (1994)

We report the development and validation of an MDS-based cognitive index, the MDS Cognition Scale (MDS-COGS), by evaluating it against two popular dementia rating scales, the Global Deterioration Scale (GDS) and the Mini-Mental State Examination (MMSE). A Cross-sectional study. Two hundred nursing home residents. Each study participant was assessed on the GDS and the MMSE by trained medical students. At the same time, but independent of the medical students, a geriatric nurse completed the Minimum Data Set (MDS) instrument on each participant. The Cognitive Performance Scale (CPS), a categorical measure of cognition that uses MDS items, was compared with the GDS in 133 subjects, using a split-sample technique. The GDS was found to be more appropriate as a 4-stage than a 7-stage scale, with GDS stages 1-4 acting as a single stage. The CPS showed very poor percent agreement with GDS stages 5 and 7 (50% or less) and, therefore, was revised by adding other MDS predictors. The new instrument, designated MDS-COGS, is a 0-10 point scale generated from eight MDS cognitive items. The MDS-COGS was then validated against the 4-stage GDS and MMSE in the remaining 67 nursing home residents. Chance-corrected agreement (kappa) between the MDS-COGS and GDS in the 67 subjects was 0.80 (95% CI = 0.70, 0.88), and percent agreement with GDS stages 5 and 7 was 60% and 85%, respectively. The MDS-COGS was also demonstrated to be a valid measure of cognitive impairment as defined by the MMSE, with sensitivity, specificity, chance-corrected agreement (kappa), and area under the ROC curve, all above 0.80. The MDS Cognition Scale, the MDS-COGS, provides a valid measure of the presence and severity of cognitive impairment in nursing home residents using items from the Minimum Data Set.

Urinary tract infection in long-term-care facility residents.

L Nicolle (2000)

Urinary tract infection is the most frequent bacterial infection in residents of long-term-care facilities. Most infections are asymptomatic, with a remarkable prevalence of asymptomatic bacteriuria of 15%-50% among all residents. The major reasons for this high prevalence are chronic comorbid illnesses with neurogenic bladder and interventions to manage incontinence. Prospective, randomized, comparative trials of therapy and no therapy for asymptomatic bacteriuria among nursing home residents have repeatedly documented that antimicrobial treatment had no benefits. However, there is substantial diagnostic uncertainty in determining whether an individual with a positive urine culture has symptomatic or asymptomatic infection when there is clinical deterioration and there are no localized findings. In the noncatheterized resident, urinary infection is an infrequent source of fever but may not be definitively excluded. The use of antimicrobials for treatment of urinary infection is part of the larger concern about appropriate antimicrobial use in long-term-care facilities and the impacts of the selective pressure of antimicrobials on colonization and infection with resistant organisms.
