The Rbans Effort Index: Base Rates In Geriatric Samples, K. Duff, C. Spering, S. O'Bryant, L. Beglinger, D. Moser, J. Bayless, Kennith Culp, J. Mold, R. Adams, J. Scott

Kennith R. Culp

The Effort Index (EI) of the RBANS was developed to assist clinicians in discriminating patients who demonstrate good effort from those with poor effort. However, there are concerns that older adults might be unfairly penalized by this index, which uses uncorrected raw scores. Using five independent samples of geriatric patients with a broad range of cognitive functioning (e.g., cognitively intact, nursing home residents, probable Alzheimer's disease), base rates of failure on the EI were calculated. In cognitively intact and mildly impaired samples, few older individuals were classified as demonstrating poor effort (e.g., 3% in cognitively intact). However, in the more …

Risk For Acute Confusion In Sensory-Impaired, Rural, Long-Term-Care Elders, P. Cacchione, Kennith Culp, M. Dyck, J. Laing

Kennith R. Culp

Acute confusion is a common geriatric syndrome in long-term care (LTC) elders with prevalence rates of 10% to 39%. Sensory impairment, specifically vision and hearing impairment, is even more common in LTC, with prevalence rates of 40% to 90%. The purpose of this study was to investigate the risk relationship between sensory impairment and the development of acute confusion in LTC elders. Each resident (N = 114) underwent sensory screening and then was followed for 28 days to monitor for the onset of acute confusion. Twenty residents (17.5%) developed acute confusion, 60 residents (52.6%) were found to be visually impaired, …

Hydration And Acute Confusion In Long-Term Care Residents... Including Commentary By Lindgren Cl And Mills Em With Author Response, Kennith Culp, J. Mentes, B. Wakefield

Kennith R. Culp

Although it is generally appropriate for a healthy adult to consume 2000 to 2500 ml per day, the literature does not address evaluating any standard. The objective here was to develop a weight-based hydration management intervention and evaluate the impact of this on the incidence of acute confusion (AC) using an N = 98. The intervention consisted of a fluid intake goal based on 100 ml per kg for the first 10 kg, 50 ml/kg for the next 10 kg, and 15 ml for the remaining body weight. The treatment group received instruction and assistance on the fluid goal and …

Risk Factors And Outcomes Associated With Hospital Admission For Dehydration, B. Wakefield, J. Mentes, J. Holman, Kennith Culp

Kennith R. Culp

The hospital admission rate for dehydration is one of the Agency for Healthcare Research and Quality Prevention's Quality Indicators, which are considered screening tools for potential quality issues. Thus, admission for dehydration may reflect the quality of care provided in community settings. Using a case-control design, this study estimated the incidence, risk factors, and outcomes of dehydration in adults admitted to the hospital. The overall prevalence rate for three International Classification of Diseases codes for dehydration at admission was 0.55%. Cases and controls differed significantly on a number of clinical variables at admission, including weight, body mass index, pulse, blood …

Reducing Hydration-Linked Events In Nursing Home Residents... Including Commentary By Godkin D, J. Mentes, Kennith Culp

Kennith R. Culp

The authors used a quasi-experimental treatment and control group design with 49 participants from four nursing homes to test the effectiveness of an 8-week hydration intervention in reducing hydration-linked events (HLEs). A Kaplan Meier survival curve with log rank test was calculated to determine incidence and time to occurrence of a HLE. Incidence of and time to a HLE did not differ between the treatment and control groups over an 8-week period (p > .05). However, treatment group participants were found to be more frail, more cognitively impaired and more at risk for acute confusion than the control group participants. Although …

Screening For Acute Confusion In Elderly Long-Term Care Residents, Kennith Culp, Toni Tripp-Reimer, K. Wadle, B. Wakefield, J. Akins, Paula Mobily, M. Kundradt

Kennith R. Culp

While acute confusion (AC) is frequently studied in the hospitalized elderly population, this phenomena has been largely ignored in elders who are residents in long-term care (LTC) facilities. The purpose of this study was to estimate the prevalence of AC in older LTC residents, the antecedent conditions present at the time of the AC event and the recognition rate of AC when assessed by staff nurses in two LTC facilities. This is a descriptive, longitudinal study with a 14 day follow-up period which incorporates a screening algorithm using AC instruments with established psychometric properties. A behavioral symptom instrument was also …

Antidepressant Treatment Of Depression In Rural Nursing Home Residents, C. Kerber, M. Dyck, Kennith Culp, Kathleen Buckwalter

Kennith R. Culp

Under-diagnosis and under-treatment of depression are major problems in nursing home residents. The purpose of this study was to determine antidepressant use among nursing home residents who were diagnosed with depression using three different methods: (1) the Geriatric Depression Scale, (2) Minimum Data Set, and (3) primary care provider assessments. As one would expect, the odds of being treated with an antidepressant were about eight times higher for those diagnosed as depressed by the primary care provider compared to the Geriatric Depression Scale or the Minimum Data Set. Men were less likely to be diagnosed and treated with antidepressants by …


Modeling Mortality Risk In Hemodialysis Patients Using Laboratory Values As Time-Dependent Covariates, Kennith Culp, M. Flanigan, E. Lowrie, N. Lew, B. Zimmerman Oct 2011

Modeling Mortality Risk In Hemodialysis Patients Using Laboratory Values As Time-Dependent Covariates, Kennith Culp, M. Flanigan, E. Lowrie, N. Lew, B. Zimmerman

Kennith R. Culp

Proportional hazards analyses assume that the magnitude of mortality risk for a predictor variable remains proportional over time. In a time-dependent model, the explanatory variable violates this assumption, and repeat observations are required to accommodate the change in risk that occurs over time. Using a retrospective cohort design, we tested the following laboratory values for a time-by-covariate interaction: hematocrit (HCT), serum albumin (ALB), and serum creatinine (CR). A random sample of 4,083 hemodialysis patients whose specimens were analyzed in a central laboratory over a 3-year period served as the study group. Using the baseline observation, we discovered significant probability values …

Postadmission Dehydration: Risk Factors, Indicators, And Outcomes, B. Wakefield, J. Mentes, J. Holman, Kennith Culp

Kennith R. Culp

Detecting and treating dehydration in hospitalized patients is critical because of the adverse outcomes associated with this condition. Using a case-control design, this study estimated the incidence, risk factors, and outcomes of dehydration in hospitalized adults. The overall incidence rate for developing one of three ICD-9 codes for dehydration during a hospital stay was 3.5%. Cases and controls differed significantly on a number of clinical variables on admission; a large percentage of patients may have had dehydration on admission to the hospital. Mortality rates at 30 and 180 days postdischarge were significantly higher when dehydration was present. Patients may be …
