Factors associated with falls during hospitalization in an older adult population.

BACKGROUND: Falls of hospitalized older adults are of concern for patients, family members, third-party payers, and caregivers. Falls are the most common safety incident among hospitalized patients with fall rates from 2.9-13 per 1,000 patient days. Little effectiveness research has been conducted on nursing interventions and other variables associated with falls of older adults during hospitalization. PURPOSE: The purpose of this exploratory outcomes effectiveness study was to examine variables associated with falls during hospitalization of older adults. METHOD: An effectiveness research model composed of patient characteristics, clinical conditions, nursing unit characteristics, medical, pharmacy, and nursing interventions was tested using generalized estimating equations (GEE) analysis. The sample consisted of 10,187 hospitalizations of 7,851 patients, aged 60 or older, admitted for acute care services over a 4-year period. Those included in the sample either had received the Nursing Interventions Classification (NIC) intervention of Fall Prevention (defined as "instituting special precautions with patient at risk for injury from falling" [Dochterman & Bulechek, 2004, p. 363]) or were at risk for falling as defined by a fall risk assessment scale. Data were obtained retrospectively from 9 clinical and administrative data repositories from 1 tertiary care hospital. DISCUSSION: Variables that were positively associated with falls, after controlling for other variables in the model, included several medical and nursing treatments; several types of medications including antidepressants, benzodiazepines, antipsychotic, and psychotropic agents; and several types of nursing treatments including restraints and neurologic monitoring (at low use rates of < 2 times a day). Variables inversely associated with falls included registered nurse (RN) skill mix, pressure ulcer care, pain management, and tube care. CONCLUSIONS: The study demonstrates the importance of conducting interdisciplinary effectiveness research that includes nursing care. Most of the variables associated with falls were interventions (medical, pharmacy, and nursing). Dose of nursing treatments and RN skill mix were also associated with falls.

The unique contribution of the nursing intervention pain management on length of stay in older patients undergoing hip procedures.

The purpose of this study was to examine the unique contribution of the nursing intervention pain management on length of stay (LOS) for 568 older patients hospitalized for hip procedures. Propensity-score-adjusted analysis was used to determine the effect of pain management on LOS. The LOS for hospitalizations that received pain management was 0.78 day longer than that for hospitalizations that did not receive pain management. Other variables that were predictors of LOS included several context-of-care variables (e.g., time spent in the intensive care unit, registered nurse skill mix, etc.), number of medical procedures and unique medications, and several other nursing interventions.

The effect of high nursing surveillance on hospital cost.

PURPOSE: The purpose of this study was to determine the cost of one nursing treatment, surveillance, for older, hospitalized adults at risk for falling. DESIGN: An observational study using information from data repositories at one Midwestern tertiary hospital. The inclusion criteria included patients age>60 years, admitted to the hospital between July 1, 1998 and June 31, 2002, at risk for falls or received the nursing treatment of fall prevention. METHODS: Data came from clinical and administrative data repositories that included Nursing Interventions Classification (NIC). The nursing treatment of interest was surveillance and total hospital cost associated with surveillance was the dependent variable. Propensity-score analysis and generalized estimating equations (GEE) were used as methods to analyze the data. Independent variables related to patient characteristics, clinical conditions, nurse staffing, medical treatments, pharmaceutical treatments, and other nursing treatments were controlled for statistically. FINDINGS: The total median cost per hospitalization was $9,274 for this sample. The median cost was different (p=0.050) for patients who received high versus low surveillance. High surveillance delivery cost $191 more per hospitalization than did low surveillance delivery. CONCLUSION: Propensity scores were applied to determine the cost of surveillance among hospitalized adults at risk for falls in this observational study. The findings show the effect of high surveillance delivery on total hospital cost compared to low surveillance delivery and provides an example of a useful method of determining cost of nursing care rather than including it in the room rate. More studies are needed to determine the effects of nursing treatments on cost and other patient outcomes in order for nurses to provide cost-effective care. Propensity scores were a useful method for determining the effect of nursing surveillance on hospital cost in this observational study. CLINICAL RELEVANCE: The results of this study along with possible clinical benefits would indicate that frequent nursing surveillance is important and might support the need for additional nursing staff to deliver frequent surveillance.

The effects of hospitalization on multiple units.

Patients are often cared for on multiple units during the course of a hospitalization. This study used general linear modeling and logistic regression analyses to demonstrate the effect of hospitalization on multiple units upon selected nursing treatments, resource use, and clinical outcomes. Primary medical diagnosis, comorbid medical conditions, and severity of illness were controlled for in the analyses. A significant association was found between hospitalizations on multiple units and selected nursing treatments, resource use, and all clinical outcomes except for mortality. Nurses play a central role in coordinating the care that patients receive across inpatient units and are positioned to develop and implement strategies to mediate the negative impacts associated with patients moving across multiple units.

Measuring the dose of nursing intervention.

PURPOSE: To increase awareness of the many issues involved in measuring the dose of nursing intervention in nursing interventions effectiveness research. METHODS: Identify critical issues in measurement of the dose of nursing intervention and discuss decisions regarding dosage measurement made in a study of the effectiveness of nursing interventions. FINDINGS: A single method can be applied to resolve two critical issues in intervention dosage measurement. CONCLUSIONS: Those conducting nursing interventions effectiveness research must think explicitly about how intervention dosage will be measured and reported so that dosage can be replicated in research and practice. PRACTICE IMPLICATIONS: Measuring and reporting the dose of nursing intervention in research is essential to the development of an evidence base adequate to support practice.

Patterns of nursing intervention use across 6 days of acute care hospitalization for three older patient populations.

PURPOSE: The purpose was to (a) identify frequently used nursing interventions, and (b) describe patterns of interventions used for each of the three patient groups. METHODS: This secondary data analysis used data from an academic medical center where the Nursing Interventions Classification (NIC) was used to electronically document nursing care. Descriptive statistics describe the types, frequencies, and patterns of NIC interventions delivered to three older acute care populations. FINDINGS: Four NIC treatments were frequently used in all patient groups. There were also NIC treatments and patterns of treatments that were unique to each group. CONCLUSIONS AND IMPLICATIONS: Using standardized nursing language in electronic medical records (EMRs) enables data extraction and analysis. Data extracted from EMRs provides nurse administrators with a tool to guide decisions regarding nurse staffing, education, evaluation, and resource allocation.

Cost of care for seniors hospitalized for hip fracture and related procedures.

Hospitalization and treatment for hip fracture and elective hip replacement surgery are increasing as the number of elderly increases and with new surgical breakthroughs. Little research has been conducted on the interventions and other variables that impact cost of care; no research has been published that includes the impact of nursing care on hospital cost. To explain the cost of hospital care that includes nursing interventions for an older patient population hospitalized for a hip fracture and/or related procedure. An effectiveness research model composed of patient characteristics, clinical conditions, nursing unit characteristics, medical, pharmacy, and nursing interventions related to the outcome of hospital cost was tested using GEE analysis. The analysis included 195 variables systematically reduced to 71 that were then examined in a sample of 568 hospitalizations (n = 523 patients, > or = 60 years old) admitted for treatment of a hip fracture or elective hip procedure over a 4-year period. Data were obtained retrospectively from nine clinical and administrative data repositories from one tertiary care hospital. The best predictors of increased hospital cost were the nursing intervention of Tube Care, the level of RN staffing below the unit's average, total number of medical procedures, total number of different medications, and low levels of the nursing intervention of Surgical Preparation. More RN hours per patient day and some nursing interventions were associated with reduced cost. The study demonstrates the importance of conducting effectiveness research in nursing. Some nursing interventions were associated with increased cost and some with decreased cost, but when compared with medical and pharmacy interventions, fewer nursing interventions were associated with increased cost. Inadequate RN staffing raised cost whereas increased RN staffing was associated with lower costs.

Nursing interventions and other factors associated with discharge disposition in older patients after hip fractures.

BACKGROUND: The research on hip fractures has been focused on surgical procedures for hip fracture repair; little is known about the contribution of nursing interventions to outcomes. OBJECTIVES: To investigate factors, including nursing interventions, associated with the discharge destination of an older patient population hospitalized for a fractured hip or an elective hip procedure. Nursing interventions used during the hospitalized period are identified. METHODS: A design model composed of patient characteristics; clinical conditions; nursing unit characteristics; and medical, pharmacy, and nursing interventions related to the outcome of discharge disposition was tested using generalized estimating equations analysis. A total of 116 variables were examined in a sample of 569 hospitalizations from 524 patients aged 60 years and older admitted for treatment of a hip fracture or elective hip procedure in one tertiary care agency over a 4-year period. Data were obtained retrospectively from five clinical databases. RESULTS: Fifty-four percent of the population was discharged to a location other than to home. The predictors of discharge to home were a younger age, admission from home, and having a spouse, as well as receipt of intravenous solutions, diagnostic ultrasound, a lower number of medications, and moderate use of the nursing intervention of bathing. The identification of nursing interventions indicates that those who received routine nursing care for this condition returned home while those who required interventions for complications or prevention of complications were discharged to an institution. DISCUSSION: Using a standardized nursing language with the hospital's information system can provide nurses and others with information that demonstrates the contribution of nursing care to outcomes, including the outcome of discharge to home.

Cost of hospital care for elderly at risk of falling.

The variables that relate to cost of hospital care for a large sample of elderly patients at risk for falling are examined. The chief predictors of cost of hospitalization were medical, pharmacy, and nursing interventions. Use of nursing interventions, on average, raised the median hospital cost less than use of medical or pharmacy interventions. Using a standardized nursing language with the hospital's information system can provide nurses with information that demonstrates the cost effectiveness of their interventions.
