Approximately one-third of adults over 65 years old are reported to fall each year. Those living in institutions fall three times that rate (1.5 falls per bed per year), with as many as 25 percent of institutional falls resulting in fracture, laceration or need for hospital care. 1-4 One method of determining causes of falls is Root Cause Analysis (RCA)(5, 6). Aggregate root cause analyses (7) examine multiple falls for a specific time period. Purpose of the Study: This descriptive study examined aggregate fall RCA s from 97 Veterans Health Administration (VHA) facilities that were submitted during the first six months of the program initiation and during the pilot phase of the program (time span of October 1999 to June 2002). The purpose was to study relationships between actions and reported reductions in fall and related injuries. These findings may be useful to those implementing fall prevention programs.
Methods: Two members of the research team coded the 176 RCA s and two other members of the research team interviewed sites about action implementation. We entered results of interviews and coding of the root cause analyses into a database. We then examined the relationships between actions and outcomes. For example we examined if sites that implemented toileting programs also reported reductions in fall rates or major injuries. We reported descriptive statistics for root causes and actions; as well as aids and barriers to implementing actions. We analyzed the relationship between implemented actions and reported reductions in falls or major injuries, using non-parametric correlation analysis (Spearman s rho); and analyzed relationships between reported reductions in falls and major injuries, and the use of outcome measures and implementation strategies. Fall rates and reductions in major injuries were by self-report. Results: The RCA S aggregated 10,701 falls producing 17 types of root causes and 27 types of actions. 435 (61.4%) of the 745 actions had been implemented and 148 (20.9%) partially implemented. Forty four percent of root causes were policy or procedure problems, 23% communication problems, 16% more training, 13% environmental causes and 4% fatigue or scheduling problems. (Figure 1) More specific root-cause categories reported are displayed in Figure 2. We analyzed each action to see whether it addressed the root cause it was suppose to address and found that 95% (708) of the actions did, in fact, address the root cause. Using the RCA Team to implement change was associated with improved implementation, while neglecting to get staff feedback before implementing change, and lack of time and resources to implement change were barriers. 34.4% reported reducing falls and 38.9% reported reducing major injuries due to falls; (figure 3) and actions associated with these
reductions were focused on making specific clinical changes, rather than policy changes or educating staff. Interventions associated with improved clinical outcomes included environmental assessments (r =.121, p =.012), toileting interventions; (falls, r=.102, p=.033) (major injuries r =.124, p =.010), interventions that addressed the root cause, (r =.094, p =.010) and actions that were the responsibility of a single person (as opposed to a group) (r =.10, p =.006). Participation in a Collaborative Breakthrough Series on reducing falls and injuries due to falls was correlated with reported reductions in falls (r =.217, p = 0.33) and major injuries (r =.335, p =.001). Conclusions and Implications: Actions focused on clinical changes are more effective than policy changes or staff education. Using RCA teams to implement changes, giving an individual responsibility for implementing actions, getting staff feedback before implementing changes, and giving change teams time and resources can increase chances of implementation. Using implementation alone is not a good measure of improved clinical outcomes; it is important to measure actual changes in clinical outcomes. Lastly, participation in the Falls Breakthrough Series appears to have helped facilities reduce falls and injuries due to falls. References: 1. Rubenstein L, Josephson K, Robbins A.
