Falls: an examination of three reporting methods in nursing homes.

OBJECTIVE: To examine the concordance of various fall reporting methods and to use the results to recommend a preferred method of ascertaining fall frequency for residents of nursing homes, both for research and in the collection of federally mandated nursing home data. DESIGN: A cohort study followed for 858 patient months, with a mean individual follow-up of 6.6 months. MEASUREMENTS: Falls were independently ascertained monthly by three methods: review of administrative incident reports, nursing home chart abstraction, and structured interview of subjects. Concordance of events was assessed using measures of simple agreement and Kendall's Tau-b. Simple correlation and multiple regression were used to evaluate the relation of age, sex, gender, depression, mental status, and functional status with degree of concordance between self-reported falls and chart-recorded falls. SETTING: One academic and six community nursing homes in San Antonio, Texas. PARTICIPANTS: 131 long-stay nursing home residents, greater than 60 years of age, dependent in at least two activities of daily living, and mildly cognitively impaired. RESULTS: Falls were ascertained in 74 of the 131 individuals; 53 subjects fell 124 times by incident report, 58 had 140 falls according to chart review, and 66 subjects self-reported 232 falls. Greatest agreement between reporting methods was shown for incident report and chart review, with a Kendall's Tau-b of 0.88; self-report and chart-review agreement was 0.56; and self-report and incident agreement was 0.53. Estimated total fall events were more often (P = 0.001) identified by chart review (92%) than incident report (82%). Although concordance was higher for non-fallers, no significant relationships were observed between concordance and age, sex, race, depression, mental status, and functional status. Also, there was no systematic relationship between length of follow-up and degree of concordance. CONCLUSIONS: Fall frequency varies by ascertainment method, with chart review reflecting a greater number of fall events than the traditionally counted incident reports.

Medical treatment preferences of nursing home residents: relationship to function and concordance with surrogate decision-makers.

OBJECTIVE: To describe treatment preferences of nursing home residents, concordance with decisions by self-selected proxies and to establish the relationship of sociodemographic and functional measures to decisions. SETTING AND SUBJECTS: 52 patient-proxy pairs at a Veterans Affairs nursing home. METHODS: Treatment preferences were elicited from residents and proxies regarding cardiopulmonary resuscitation, mechanical ventilation, and intensive care unit care. Hospitalization, intravenous antibiotics, intravenous fluid administration, and tube feeding were presented in three separate health scenarios. Concordance was determined for the entire interview and separately for each scenario. Treatment-seeking intensity and decision-making consistency were scored and used to explore associations with sociodemographic variables and function. RESULTS: Subjects were predominantly male (97%) and non-Hispanic white (74%); average age was 70 +/- 12 years, with 4 +/- 2.9 diagnoses. Residents accepted 70% of all treatments. The proportion of subjects accepting interventions declined parallel to health status in each scenario. Only 7/52 (13%) subjects made inconsistent decisions. Resident treatment acceptance was inversely associated with GDS scores but not associated with any other sociodemographic or functional measure. Concordance with proxies was no greater than chance. Proxies' decisions were not systematically biased against resident preferences or influenced by patient characteristics. CONCLUSIONS: Veterans desired most treatments, but adjusted preferences according to health status and were not inconsistent. Depressive symptoms should be addressed prior to advance directive selection. The patient remains the best source of information, but proxies' decisions exhibit no bias and are not affected by patient status.

The impact of physical therapy on nursing home patient outcomes.

The objective of this retrospective study was to assess the intensity and outcome of individual components of interdisciplinary care, including physical therapy, in a teaching nursing home. Two independent reviewers abstracted records from 90 consecutive patients admitted to the nursing home. They rated intensity and outcome of each program component using a structured, standardized data-abstraction form. Program components were physical therapy, speech therapy, psychosocial therapy, medication adjustment, and other medical and nursing care. Physical therapy and medication adjustment were the most frequently received therapies. Eighty-eight percent of the patients receiving high-intensity physical therapy and 33% of the patients receiving moderate-intensity physical therapy improved. For medication adjustment, 93% and 72% of the high- and moderate-intensity groups, respectively, improved. In univariate analyses, physical therapy intensity and age were associated with improvement. Baseline function in activities of daily living and cognitive function were not associated with physical therapy outcome. A stepwise multiple logistic regression analysis revealed that only therapy intensity was associated with improved outcome. We conclude that physical therapy was efficacious for patients receiving high-intensity treatment. Advanced age, activities-of-daily-living status, and cognitive impairment were not associated with poor physical therapy outcome.

Physical therapy assessment and treatment protocol for nursing home residents.

This article describes a standard protocol for assessing physical function in elderly nursing home residents. Major physical dimensions that are measured with the protocol include range of motion, muscle force, muscle reflex activity, sensation, soft tissue status, balance/coordination, and posture. A practical, functionally prioritized treatment model based on the assessment is also presented. The standardized assessment and treatment plan may be useful to the physical therapist in (1) planning and prioritizing treatment, (2) identifying when goals have been met, (3) recognizing when there is a need for treatment plan modification, and (4) educating physical therapy students in applying problem-solving skills in their treatment sessions.

Screening for frailty: criteria and predictors of outcomes.

OBJECTIVE: To determine the reliability of rapid screening by clinically derived geriatric criteria in predicting outcomes of elderly hospitalized patients. DESIGN: Prospective cohort study of 985 patients screened at the time of hospital admission and followed for 1 year with respect to the outcomes of mortality, hospital readmission, and nursing home utilization. SETTING: Palo Alto Veterans Affairs Medical Center, a tertiary care teaching hospital. SUBJECTS: Male patients 65 years of age and older admitted to the Medical and Surgical services during the period from October 1, 1985 through September 30, 1986. RESULTS: Patients were grouped by specific screening criteria into three groups of increasing frailty: Independent, Frail, and Severely Impaired. Each criterion focused on a geriatric condition and was designed to serve as a marker for frailty. Increasing frailty was significantly correlated with increasing length of hospital stay (P less than 0.0001), nursing home utilization (P less than 0.0001), and mortality (P less than 0.0001). Multivariate analyses revealed that the clinical groups were more predictive of mortality and nursing home utilization than were age or Diagnosis-Related Groups (DRGs). Rehospitalization was unrelated to age, clinical group, or DRG, suggesting that utilization may not be driven by the clinical factors measured in this study. CONCLUSIONS: Rapid clinical screening using specific geriatric criteria is effective in identifying frail older subjects at risk for mortality and nursing home utilization. Our findings suggest that geriatric syndromes are more predictive of adverse outcomes than diagnosis per se. This well operationalized screening process is inexpensive as well as effective and could easily be introduced into other hospital settings.

Targeting the hospitalized elderly for geriatric consultation.

This empirical study reports the proportion of hospitalized elderly patients who were identified as frail. As a part of a randomized controlled trial, standardized criteria were developed to target the frail hospitalized elderly for geriatric consultation. Twelve-hundred patients aged 65 years and older admitted to the medical and surgical services at the Palo Alto Veterans Administration Medical Center were screened. Because of administrative exclusions of the randomized controlled trial (eg, short stay, lived too far away), 749 (62%) were excluded from the clinical screening process. The remaining 451 patients received clinical screening. Of these patients, almost two thirds (64%) were considered "too independent" to benefit from geriatric consultation (ie, independent in activities of daily living with short term illness), while 12% were judged "too impaired" to benefit (ie, had severe dementia or terminal cancer). Only 24% of those clinically screened (9% of the entire sample) were considered appropriate for geriatric consultation. Strikingly, over 42% of those patients aged 76 or older, were judged "too independent." These data suggest that a large majority of the hospitalized elderly may be too well to benefit from geriatric consultation, thus making targeting by age alone inefficient. A realistic estimate of the percentage of hospitalized patients appropriate for geriatric intervention lies somewhere between 18% (the combined percentage of those found appropriate and those already enrolled in geriatric programs) and 24% (the proportion of the clinically evaluated group found appropriate). Targeting of subjects may be accomplished inexpensively using the authors' explicit criteria. Such targeting may help focus the use of interdisciplinary geriatric expertise on those most in need.(ABSTRACT TRUNCATED AT 250 WORDS)

Impact of prospective payment and discharge location on the outcome of hip fracture.

OBJECTIVE: To determine the impact of prospective payment by diagnosis-related groups (DRGs) on length of stay in the hospital, ambulatory status, and level of post-hospital care needed for patients hospitalized with hip fracture. DESIGN: Retrospective chart review of a consecutive series of cases before and after the reference date of implementation of the prospective payment system (PPS). SETTING: Academic, tertiary-care hospital. PATIENTS/PARTICIPANTS: 181 patients 69 years of age or older admitted with International Classification of Diseases (ICD) or DRG codes for hip fracture. RESULTS: Length of stay was shorter by 1.37 days in the post-PPS era (p = 0.05). Poorer discharge ambulation was found in the post-PPS group (p = 0.089). At one year, differences in ambulation and nursing home residence were found to be related not to the implementation of PPS, but rather to the nursing home to which the patient was discharged. Patients discharged to a facility with active physical rehabilitation were less likely to remain institutionalized (p = 0.0025) than those in "ordinary" nursing homes and ambulated more independently (p = 0.05). CONCLUSIONS: The PPS did not have a significant long-term impact on hip fracture outcome. Post-hospital care may be of crucial importance to the future quality of life of hip fracture patients.
