The effects of staffing on in-bed times of nursing home residents.

OBJECTIVES: To examine the effect of staffing level on time observed in bed during the daytime in nursing home (NH) residents. DESIGN: Descriptive, cross-sectional study. SETTING: Thirty-four southern California NHs. PARTICIPANTS: A total of 882 NH residents: 837 had hourly observation data, 777 had mealtime observations, 837 completed interviews, and 817 completed a physical performance test. MEASUREMENTS: Cross-sectional data collected from participants at each NH site included direct observations (hourly and mealtime), resident interviews, medical record review, and physical performance tests. RESULTS: In multivariate analyses, staffing level remained the strongest predictor of time observed in bed after controlling for resident functional measures (odds ratio=4.89; P=.042). Residents observed in bed during the daytime in more than 50% of hourly observations were observed also to experience increased daytime sleeping (P<.001) and less social engagement (P=.026) and consumed less food and fluids during mealtimes than those observed in bed in less than 50% of observations, after adjusting for resident function (P<.001). CONCLUSION: In this sample of NHs, resident functional measures and NH staffing level predicted observed time in bed according to hourly observations, with staffing level the most powerful predictor. Neither of these predictors justifies the excessive in-bed times observed in this study. Staff care practices relevant to encouraging residents to be out of bed and resident preferences for being in bed should be examined and improved. Practice recommendations regarding in-bed time should be considered, and further research should seek to inform the development of such recommendations.

Does an exercise and incontinence intervention save healthcare costs in a nursing home population?

OBJECTIVES: To determine whether an intervention that combines low-intensity exercise and incontinence care offsets some of its costs by reducing the incidence of selected health conditions in nursing home residents. DESIGN: Randomized, controlled trial with the incidence and costs of selected, acute conditions compared between a 6-month baseline and an 8-month intervention phase. SETTING: Four nursing homes. PARTICIPANTS: One hundred ninety incontinent, long-stay nursing home residents. INTERVENTION: Low-intensity, functionally oriented exercise and incontinence care were provided every 2 hours from 8:00 a.m. to 4:00 p.m. for 5 days a week for 8 months. MEASUREMENTS: Predefined acute conditions hypothesized to be related to physical inactivity, incontinence, or immobility were abstracted from residents' medical records by blinded observers during a 6-month baseline period and throughout the 8-month intervention. Conditions included those in the dermatological, genitourinary, gastrointestinal, respiratory and cardiovascular systems; falls; pain; and psychiatric and nutritional disturbances. Costs were determined using Current Procedural Terminology Center and Medicare allowable cost reimbursement at a rate of 80%. RESULTS: The intervention group had significantly better functional outcomes than the control group (strength, mobility endurance, urinary and fecal incontinence) and a reduction of 10% in the incidence of the acute conditions, which was not significant. There were no significant differences between groups in the cost of assessing and treating these acute conditions between baseline and intervention. CONCLUSION: The intervention, which is consistent with federal and clinical practice guidelines, significantly improved functional outcomes but did not reduce the incidence and costs of selected acute health conditions. The cost of implementing these labor-intensive interventions for frail nursing home residents will have to be justified based on functional and quality-of-life outcomes and are unlikely to be offset by savings in medical care costs in this population.

The effects of an exercise and incontinence intervention on skin health outcomes in nursing home residents.

OBJECTIVES: To examine skin health outcomes of an exercise and incontinence intervention. DESIGN: Randomized controlled trial with blinded assessments of outcomes at three points over 8 months. SETTING: Four nursing homes (NHs). PARTICIPANTS: One hundred ninety incontinent NH residents. INTERVENTION: In the intervention group, research staff provided exercise and incontinence care every 2 hours from 8:00 a.m. to 4:30 p.m. (total of four daily care episodes) 5 days a week for 32 weeks. The control group received usual care from NH staff. MEASUREMENTS: Perineal skin wetness and skin health outcomes (primarily blanchable erythema and pressure ulcers) as measured by direct assessments by research staff, urinary and fecal incontinence frequency, and percentage of behavioral observations with resident engaged in standing or walking. RESULTS: Intervention subjects were significantly better in urinary and fecal incontinence, physical activity, and skin wetness outcome measures than the control group. However, despite these improvements, differences in skin health measures were limited to the back distal perineal area, which included the sacral and trochanter regions. There was no difference between groups in the incidence rate of pressure ulcers as measured by research staff, even though those residents who improved the most on fecal incontinence showed improvement in pressure ulcers in one area. CONCLUSION: A multifaceted intervention improved four risk factors related to skin health but did not translate into significant improvements in most measures of skin health. Even if they had adequate staffing resources, NHs might not be able to improve skin health quality indicators significantly if they attempt to implement preventive interventions on all residents who are judged at risk because of their incontinence status.

The minimum data set weight-loss quality indicator: does it reflect differences in care processes related to weight loss?

OBJECTIVES: To determine whether nursing homes (NHs) that score differently on prevalence of weight loss, according to a Minimum Data Set (MDS) quality indicator, also provide different processes of care related to weight loss. DESIGN: Cross-sectional. SETTING: Sixteen skilled nursing facilities: 11 NHs in the lower (25th percentile-low prevalence) quartile and five NHs in the upper (75th percentile-high prevalence) quartile on the MDS weight-loss quality indicator. PARTICIPANTS: Four hundred long-term residents. MEASUREMENTS: Sixteen care processes related to weight loss were defined and operationalized into clinical indicators. Trained research staff conducted measurement of NH staff implementation of each care process during assessments on three consecutive 12-hour days (7 a.m. to 7 p.m.), which included direct observations during meals, resident interviews, and medical record abstraction using standardized protocols. RESULTS: The prevalence of weight loss was significantly higher in the participants in the upper quartile NHs than in participants in the lower quartile NHs based on MDS and monthly weight data documented in the medical record. NHs with a higher prevalence of weight loss had a significantly larger proportion of residents with risk factors for weight loss, namely low oral food and fluid intake. There were few significant differences on care process measures between low- and high-weight-loss NHs. Staff in low-weight-loss NHs consistently provided verbal prompting and social interaction during meals to a greater proportion of residents, including those most at risk for weight loss. CONCLUSION: The MDS weight-loss quality indicator reflects differences in the prevalence of weight loss between NHs. NHs with a lower prevalence of weight loss have fewer residents at risk for weight loss and staff who provide verbal prompting and social interaction to more residents during meals, but the adequacy and quality of feeding assistance care needs improvement in all NHs.

The minimum data set urinary incontinence quality indicators: do they reflect differences in care processes related to incontinence?

PURPOSE: To determine if nursing homes that score in the lower 25th percentile (low prevalence) versus the upper 75th percentile (high prevalence) on each of two Minimum Data Set (MDS) incontinence quality indicators provide different incontinence care processes DESIGN: Cross-sectional. SUBJECTS: 347 long-term residents in 14 skilled nursing facilities for the MDS "prevalence of incontinence" indicator and 432 residents in 16 skilled nursing facilities for the MDS "prevalence of incontinence without a toileting plan" indicator. MEASURES: Nine care processes related to incontinence were defined and operationalized into clinical indicators. Research staff assessed implementation of each care process on 3 consecutive 12-hour days (7 am to 7 pm ). The assessment included resident interviews, physical performance evaluations, and chart abstraction using standardized protocols. RESULTS: Homes with lower prevalence rates on both MDS incontinence quality indicators (good outcomes) had a significantly higher proportion of participants with chart documentation of two relevant care processes: 1 an evaluation of the resident's incontinence history and 2 toileting assistance rendered by staff. However, interviews with incontinent residents capable of accurately reporting care activity occurrence showed no difference in toileting assistance frequency between homes in the upper and lower quartiles for either MDS incontinence indicator. Participants reported an average of 1.8 toileting assists per day across all homes with a narrow average frequency range between homes (1.6-2.0). These frequencies of toileting assistance are not sufficient to improve urinary incontinence. There was also no difference in the frequency of toileting assistance received by incontinent participants rated on the MDS as receiving scheduled toileting (n = 75, mean = 1.9 +/- 1.24) compared to incontinent residents rated on the MDS as not receiving scheduled toileting (n = 131, mean = 1.8 +/- 1.22). None of the homes provided chart documentation that supported staff decisions to place or not place a resident on a scheduled toileting program. CONCLUSIONS: The quality of incontinence assessment and treatment as documented by scheduled toileting interventions was poor across all homes, and the MDS incontinence quality indicators were not associated with clinically important differences in related care processes. Chart documentation that a resident was on a scheduled toileting program or received toileting assistance was not related to resident reports of the frequency of received assistance.

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

OBJECTIVES: To examine clinical outcomes and describe the staffing requirements of an incontinence and exercise intervention. DESIGN: Randomized controlled trial with blinded assessments of outcomes at three points over 8 months. SETTING: Four nursing homes. PARTICIPANTS: Two hundred fifty-six incontinent residents. INTERVENTION: 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. MEASUREMENTS: 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. RESULTS: 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. CONCLUSIONS: 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 Minimum Data Set bedfast quality indicator: differences among nursing homes.

BACKGROUND: Excessive time in bed has negative effects on both physical conditioning and functioning. There are no data or practice guidelines relevant to how nurses should manage the in-bed times of nursing home residents, although all nursing homes receive a bedfast prevalence quality indicator report generated from the Minimum Data Set. OBJECTIVES: To compare nursing homes that score in the upper and lower quartiles on the Minimum Data Set bedfast prevalence quality indicator for proportion of bedfast residents, activity and mobility nursing care, and amount of time all residents spend in bed, and to evaluate whether residents who spend more time in bed are different from those who spend less time in bed according to functional measures. METHODS: A cohort design used medical records, resident interviews, and direct observation data to compare 15 nursing homes (n = 451 residents) on the proportion of bedfast residents, the amount of time residents spent in bed, the frequency of activity, and the scores on six activity and mobility care process indicators. RESULTS: Significant differences were found between upper (i.e., higher prevalence of bedfast residents) and lower quartile nursing homes in the proportion of time residents were observed in bed (43% vs. 34%, respectively; p =.007), and in the proportion of residents who spent more than 22 hours in bed per day (18% vs. 8%, respectively; p =.002). All nursing homes underestimated the number of bedfast residents. The residents of upper quartile homes showed more activity episodes and reported receiving more walking assistance than the residents of lower quartile homes. DISCUSSION: Minimum Data Set bedfast quality indicator identified nursing homes in which residents spent more time in bed, but did not reflect differences in activity and mobility care. In fact, upper quartile homes provided more activity and mobility care than lower quartile homes. Across all the nursing homes, most of the residents spent at least 17 hours a day in bed. Further study of activity and mobility care and bedfast outcomes in nursing homes is needed, and nurses need to note the amount of time nursing home residents spend in bed.

Incidence and costs of acute medical conditions in long-stay incontinent nursing home residents.

OBJECTIVES: To determine the incidence of acute medical conditions in incontinent nursing home residents, and associated costs of diagnostic testing and treatment DESIGN: Prospective, cohort study. SETTING: Three community nursing homes. PARTICIPANTS: 161 long-stay residents with urinary incontinence in (mean age 86 years, 77% female, 92% white). MEASUREMENTS: Acute medical conditions were identified prospectively through medical record review based on standardized criteria. All diagnostic testing and treatment provided for these conditions were recorded, and related costs in the nursing home were assigned based on 1997-1998 Medicare and Medicaid reimbursement. RESULTS: The highest incidences of illness were for dermatological conditions (107 episodes per 1000 patient-weeks, involving 70% of subjects), respiratory illnesses (29 per 1000 patient-weeks, 47% of subjects) and gas-trointestinal illnesses (24 per 1000 patient-weeks, 36% of subjects). Among episodes with an incidence of at least 5 per 1000 patient-weeks, the illness events with the highest median diagnostic testing and treatment costs per episode were pneumonia, acute bronchitis, and depression. Only 42 out of the total 1071 episodes identified resulted in a hospitalization. Significant predictors of higher illness incidence included greater baseline comorbidity and higher number of routine medications (model adjusted R-square = 0.319, P = 0.021). CONCLUSION: Acute illness is very common among incontinent nursing home residents, and is generally diagnosed and treated at the nursing home site, with variation among conditions in associated costs. Important policy implications include resource allocation (including appropriate staffing patterns), educational and quality improvement activities, and future research and guideline development for the optimal management of medical conditions in the nursing home setting.
