Analysis of falls in the acute surgical and cardiovascular surgical patient

Factors associated with falls in patients with cancer hospitalized for palliative care

INTRODUCTION

In geriatrics, most risk factors associated with falls have been identified and management strategies developed accordingly. This is not the case in palliative care. The incidence rate of falls, the consequences related to falls, and other related factors were determined in elderly cancer patients hospitalized for palliative care in an exploratory study.

METHODS

All consecutive patients hospitalized with advanced cancer were included over a 1-year period. Each fall was identified and detailed by a routinely collected incident report. Associations between variables and falls were assessed.

RESULTS

Mean age of the 198 patients (116 F) was 71.0 +/- 12.1 years. Of these, 36 had a fall at least once. Delirium occurred significantly more often in fallers (p = 0.029). There was a nonsignificant trend for a higher number of prescribed drugs in fallers (n = 8.5 +/- 3.7 versus 7.5 +/- 3.2; p = 0.4) who received significantly more neuroleptics (47.2% versus 29%; p = 0.035). Environmental hazards made little contribution to patients' falls.

DISCUSSION

Characteristics of falls in palliative care appear different from those evidenced in geriatric wards. To prevent delirium while prescribing neuroleptic drugs with the greatest caution should help decrease the number of falls in this highly vulnerable group of patients.

Fall incidence and fall prevention practices at acute care hospitals in Singapore: a retrospective audit

OBJECTIVE

To investigate the incidence of falls and explore fall prevention practices at acute care hospitals in Singapore.

DESIGN

A retrospective audit to collect baseline data on (1) incidence of falls (patient fall rates and fall injury rates) and (2) fall prevention practices, was conducted in five acute care hospitals in Singapore from December 2004 to March 2005.

STUDY PARTICIPANTS

Medical record data (n = 6000) of patients admitted into the medical, surgical and geriatric units in the five hospitals.

OUTCOME MEASURES

Fall incidence was obtained from the hospital's fall databases and incident reports for the period of June 2003 to May 2004. In total, 6000 medical records from five hospitals were randomly selected, retrieved and reviewed to determine whether falls, fall assessments and interventions were being initiated and documented.

RESULTS

The number of fallers for all hospitals was 825. Analysis showed that patient fall rates ranged from 0.68 to 1.44 per 1000 patient days, and the proportion of falls associated with injury ranged from 27.4% to 71.7%. The use of a fall risk assessment tool by nurses was recorded in 77% of all the nursing records.

CONCLUSION

This study has laid the foundation for further research for fall prevention in Singapore by describing current fall rates, fall-associated injury rates and the status of fall prevention practices in acute care settings. The results will be used to inform the development of a tailored multifaceted strategy to facilitate the implementation of Fall Prevention Clinical Practice Guidelines to reduce the burden of falls and fall injuries in hospitals in Singapore.

Hospital fall risk assessment tools: a critique of the literature

There are numerous fall risk assessment tools developed for use by nurses in hospitals; however, few of them have established validity and reliability. This article will examine the current state of knowledge in regard to fall risk assessment tools through review and critique of the literature on the topic. Recommendations for future research on fall risk assessment tools will be made and a conceptual framework detailing the relationship between the variables involved in assessing the accuracy of fall risk assessment tools will be presented.

Trends in adverse events in hospitalized patients

The Institute of Medicine reported unacceptably high rates of medical error but did not identify whether this is a growing or a stabilized problem. This study used longitudinal data from all acute care hospitals in Pennsylvania to track rates of acuity-adjusted iatrogenic atelectasis, cardiac complications, complications in general, decubitus ulcers, gangrenous ulcers, falls, hemorrhage, mortality, penumonia, post-procedural infections, treatment complications, and urinary tract infections, from 1994 to 1997. More than one-half of these adverse events increased during this time. It is important to identify the causes and correct trends in hospital systems that may produce an increase in preventable adverse events.

Nursing quality outcome indicators. The North Dakota Study

The purpose of this study was to assess the feasibility and conduct a pilot study of the ANA Nursing Care Report Card Study in one state. Clinical indicators studied include agency data, skin integrity, patient falls, and nurse (n = 217) and patient (n = 924) satisfaction. Patients were well satisfied with their care. Nurses were less satisfied, with a significant difference between what was important to their satisfaction and their current level of satisfaction. Important information is included for hospital and nursing service administrators, as well as for nurses.

Outcomes of a randomized controlled trial of a clinical pharmacy intervention in 52 nursing homes

AIMS

To evaluate whether a year long clinical pharmacy program involving development of professional relationships, nurse education on medication issues, and individualized medication reviews could change drug use, mortality and morbidity in nursing home residents.

METHODS

A cluster randomised controlled trial, where an intervention home was matched to three control homes, was used to examine the effect of the clinical pharmacy intervention on resident outcomes. The study involved 905 residents in 13 intervention nursing homes and 2325 residents in 39 control nursing homes in south-east Queensland and north-east New South Wales, Australia. The outcome measures were: continuous drug use data from government prescription subsidy claims, cross-sectional drug use data on prescribed and administered medications, deaths and morbidity indices (hospitalization rates, adverse events and disability indices).

RESULTS

This intervention resulted in a reduction in drug use with no change in morbidity indices or survival. Differences in nursing home characteristics, as defined by cluster analysis with SUDAAN, negated intervention-related apparent significant improvements in survival. The use of benzodiazepines, nonsteroidal anti-inflammatory drugs, laxatives, histamine H2-receptor antagonists and antacids was significantly reduced in the intervention group, whereas the use of digoxin and diuretics remained similar to controls. Overall, drug use in the intervention group was reduced by 14.8% relative to the controls, equivalent to an annual prescription saving of A64 dollars per resident (approximately 25 pound sterling).

CONCLUSIONS

This intervention improved nursing home resident outcomes related to changes in drug use and drug-related expenditure. The continuing divergence in both drug use and survival at the end of the study suggests that the difference would have been more significant in a larger and longer study, and even more so using additional instruments specific for measuring outcomes related to changes in drug use.

Falls risk factors in the hospital setting: a systematic review

The objective of this systematic review was to summarize the best available evidence on the factors that increase the risk of patients falling during hospitalization. Studies included in the review were those that involved adult patients in hospital, that attempted to identify risk factors for falling, and used a cohort or case-control research design. The search strategy covered all major databases and including MEDLINE, CINAHL, Current Contents, Psyclit, Embase and the Cochrane Library. Results were summarized by a narrative discussion, identifying risk factors that were commonly identified in a range of practice settings. Eighteen papers met the review inclusion criteria and are reported in this paper. Factors associated with an increased risk of falling include impaired mental status, special toileting needs, impaired mobility, and a history of falling. While findings are contradictory, it appears that both medications and advanced age will also influence a patient's risk of falling.

Mechanical restraints, rehabilitation therapies, and staffing adequacy as risk factors for falls in an elderly hospitalized population

This case-control study of fall-related risk factors for elderly hospitalized patients hypothesized that the use of mechanical restraints, participation in a rehabilitation program, and staffing inadequacy increase the risk of falls. The study included 252 patients, also known as "cases," aged 60 to 85 years, who fell during the period between March 1 and December 31, 1993, in a large metropolitan hospital; and 250 "controls," randomly selected patients aged 60 to 85 years, who were matched with the cases in terms of length of stay to the day of the fall. Analysis using conditional logistic regression revealed that individuals who had been placed in a mechanical restraint at any point during their hospital stay prior to the fall (for the cases) or the selected day (for the controls) had approximately twice the risk of falling as did patients who had not been placed in restraints. Cases and controls showed no significant differences in terms of their participation in occupational therapy, physical therapy, or cardiac rehabilitation, and staffing adequacy was similar for both groups. While the finding of 2 to 4.7 times the risk for falls for those placed in a mechanical restraint only approached statistical significance, the results indicate that the risk of falling is highest soon after a patient has had to be placed in a mechanical restraint.

Adverse patient occurrences as a measure of nursing care quality

OBJECTIVE

The purpose of this study was to describe relationships among adverse patient occurrences aggregated at the unit level of measurement. Relationships between adverse occurrences and a patient acuity measure were also described.

BACKGROUND

Adverse patient occurrence data have been traditionally a major indicator of quality care in hospitals; however, few studies have examined relationships among these indicators or the usefulness of these indicators for assessing the quality of nursing care.

METHODS

A correlational design was used to examine and describe patterns of relationships among in-patient units in a tertiary care hospital. The results demonstrated positive correlations between medication error rates and patient falls; these adverse occurrences correlated negatively with pressure ulcers, infections, patient complaints, and death. Pressure ulcers, infections, patient complaints and death intercorrelated positively and also related positively to patient acuity levels.

RESULTS

An examination of these same rates for a subset of units with similar patient acuity levels revealed that most of the interrelationships among the entire set of adverse occurrence indicators were positive. When patient acuity was taken into account, these adverse outcomes appeared to indicate some common underlying characteristic of the units, such as quality of nursing care.

CONCLUSIONS

This study suggests a relationship between the adverse occurrences that were correlated (pressure ulcers, patient complaints, infection, and death) and the severity of patient illness. Medication error rates and patient fall rates were not correlated with patient acuity and are more likely to indicate quality of nursing care across all types of units.

Hospital falls: development of a predictive model for clinical practice

A retrospective case-control study related to falls was conducted at an 1,120-bed acute care tertiary hospital. The case (fall) sample consisted of 102 falls and 236 control (nonfall) charts during a 1-month period. An instrument developed by Hendrich (1988) was modified for use in the study. Demographic data and risk factors were recorded. Descriptive statistics included risk factor percentages for each sample and the corresponding univariate relative risks. Logistic regression was used to develop a multivariate risk factor model with seven risk factors. The significant risk factors were recent history of falls, depression, altered elimination patterns, dizziness or vertigo, primary cancer diagnosis, confusion, and altered mobility. The adjusted relative risks were converted to risk points to be used to assess a patient's level of fall risk. Within the data set, a sensitivity of 77% (79 of 102) and specificity of 72% (169 of 236) were calculated. The model was cross-validated in a 1987 data set with a sensitivity of 83% (59 of 71) and specificity of 66% (106 of 161).
