ABSTRACT OBJECTIVES: To systematically document the implementation, components, comparators, adherence, and effectiveness of published fall prevention approaches in U.S. acute care hospitals. DESIGN: Systematic review. Studies were identified through existing reviews, searching five electronic databases, screening reference lists, and contacting topic experts for studies published through August 2011. SETTING: U.S. acute care hospitals. PARTICIPANTS: Studies reporting in-hospital falls for intervention groups and concurrent (e.g., controlled trials) or historic comparators (e.g., before-after studies). INTERVENTION: Fall prevention interventions. MEASUREMENTS: Incidence rate ratios (IRR, ratio of fall rate postintervention or treatment group to the fall rate preintervention or control group) and ratings of study details. RESULTS: Fifty-nine studies met inclusion criteria. Implementation strategies were sparsely documented (17% not at all) and included staff education, establishing committees, seeking leadership support, and occasionally continuous quality improvement techniques. Most interventions (81%) included multiple components (e.g., risk assessments (often not validated), visual risk alerts, patient education, care rounds, bed-exit alarms, and postfall evaluations). Fifty-four percent did not report on fall prevention measures applied in the comparison group, and 39% neither reported fidelity data nor described adherence strategies such as regular audits and feedback to ensure completion of care processes. Only 45% of concurrent and 15% of historic control studies reported sufficient data to compare fall rates. The pooled postintervention incidence rate ratio (IRR) was 0.77 (95% confidence interval = 0.52-1.12, P = .17; eight studies; I(2) : 94%). Meta-regressions showed no systematic association between implementation intensity, intervention complexity, comparator information, or adherence levels and IRR. CONCLUSION: Promising approaches exist, but better reporting of outcomes, implementation, adherence, intervention components, and comparison group information is necessary to establish evidence on how hospitals can successfully prevent falls.

    ABSTRACT: This study aimed to assess the relationship between adverse events (AEs) and changes in the levels of disability from admission to discharge during inpatient rehabilitation programs.A prospective cohort study was conducted among a cohort of inpatients (216 older adults) admitted to a rehabilitation unit. The occurrences of any AE were reported. The level of disability regarding mobility activities was estimated using the disability qualifiers from the International Classification of Functioning, Disability, and Health. Changes in the levels of disability between admission and discharge were assessed. Baseline-measured covariates were also selected.Regarding all 4 disability levels ("no limitation," "mild," "moderate," "severe," and "complete disability"), a total of 159 participants experienced an improvement at discharge (126 participants progressed 1 level, whereas 33 improved 2 disability levels), 56 made no change, and no participants experienced a decline.The occurrence of fall-related events and the diagnostic group (musculoskeletal system) are specific predictive factors of change in the level of disability. The odds of undergoing a change in any disability level between admission and discharge decreases by 68% (1-0.32) when patients experience fall-related events (odds ratio [OR] = 0.32, 95% confidence interval [CI] = 0.11-0.97, P = 0.041) and increases for individuals with musculoskeletal conditions (OR = 3.91, 95% CI = 1.34-11.38, P = 0.012).Our findings suggest that increased efforts to prevent the occurrence of these AEs, together with early interventions suited to the diagnosis of the affected system, may have a positive influence on the improvement of disability. Further studies should evaluate disability over time after discharge to obtain a better sense of how transient or permanent the associated disability may be.

    ABSTRACT: There is no conclusive evidence that hospital fall prevention programs can reduce the number of falls. We aimed to investigate the effect of a targeted individualized falls prevention program in a geriatric rehabilitation hospital. This was a two-stage cluster-controlled trial carried out in five geriatric rehabilitation wards. Participants were 752 patients with mean age 83.2 years. The intervention was a two-phase targeted intervention falls prevention program. The intervention included an assessment of patient's risk by a risk assessment tool and an individual management that includes medical, behavioral, cognitive and environmental modifications. Patients with moderate risk received additionally orientation guidance, and mobility restriction. Patients determined as high risk were additionally placed under permanent personal supervision. Outcome measures were falls during hospital stay. In both stages of the trial, intervention and control wards were almost similar at baseline for individual patient characteristics. Overall, 37 falls occurred during the study. No significant difference was found in fall rates during follow-up between intervention and control wards: 1.306 falls per 1000 bed days in the intervention groups and 1.763-1.826 falls per 1000 bed days in the control groups. The adjusted hazard ratio for falls in the intervention groups was 1.36 (95 % confidence interval 0.89-1.77) (P = 0.08) in the first stage and 1.27 (95 % confidence interval 0.92-1.67) (P = 0.12) in the second stage. These results suggest that in a geriatric rehabilitation hospital a targeted individualized intervention falls prevention program is not effective in reducing falls.

    ABSTRACT: OBJECTIVES: To determine the proportion of variation in long-term fall rates attributable to variability between rather than within hospital units and to identify unit- and hospital-level characteristics associated with persistently low- and high-fall units. DESIGN: Retrospective study of administrative data on inpatient falls. Eighty low-fall and 74 high-fall units were identified based on monthly rankings of fall rates. Unit and hospital-level characteristics of these units were compared. SETTING: U.S. general hospitals participating in the National Database of Nursing Quality Indicators. PARTICIPANTS: Nonsubspecialty medical units (n = 800) with 24 consecutive months of falls data. MEASUREMENTS: Monthly self-reported unit fall rates (falls per 1,000 patient-days). RESULTS: An estimated 87% of variation in 24-month fall rates was due to between-unit differences. With the exception of patient-days, a proxy for unit bed size, low- and high-fall units did not differ on nurse staffing or any other unit or hospital characteristic variable. CONCLUSION: There are medical units with persistently low and persistently high fall rates. High-fall units had higher patient volume, suggesting patient turnover as a variable for further study. Understanding additional factors underlying variability in long-term fall rates could lead to sustainable interventions for reducing inpatient falls.
