Latest / Safe As Podcast / E15: Root Cause Analyses (RCA) and incident prevention: do they work?
Transcript
- 0:07In industry, root cause analysis, or Rcas, are a widely
- 0:12used collection of approaches and tools.
- 0:15They're meant to be a rigorous process for digging deep after
- 0:18an adverse event, identifying contributing factors in crafting
- 0:22solutions that will prevent reoccurrences.
- 0:25The expectation is that an RCA leads to real, tangible
- 0:28improvements. But what does the latest
- 0:31research actually show about the effectiveness of Rcas?
- 0:35Are Rcas consistently delivering on their promises to make our
- 0:38workplaces safer? Or are we sometimes just going
- 0:41through the motions without seeing the desired impact?
- 0:45Good day, everyone. I'm Ben Hutchinson, This is Safe
- 0:47as a podcast dedicated to the thrifty analysis of safety,
- 0:51risk, and performance research. Visit safetinsights.org for more
- 0:55research. Today's study is from Martin
- 0:58Delgado ET al 2020, entitled How much of Root Cause analysis
- 1:04translates into improved patient Safety?
- 1:07A systematic review published in Medical Principles and Practise.
- 1:11It's a systematic review that explored whether root cause
- 1:14analysis are effective to reduce your recurrence of avoidable
- 1:18adverse events in healthcare, or else call them adverse events.
- 1:2221 studies were included, nine of moderate quality, 5 of
- 1:27considerable quality, seven of high quality.
- 1:30It's another healthcare study. As you picked up, it's worth
- 1:33highlighting that RCA is an umbrella term.
- 1:36It's not some monolithic tool, but rather includes many
- 1:40different tools and methods. Because of this study design and
- 1:44the overall limited evidence, they couldn't sort the study
- 1:47into a comparison of the specific RCA tools.
- 1:51So what did they find? Overall, they found the
- 1:55effectiveness of Rcas is unclear and inconsistent.
- 1:59According to the paper, it's not clear if root cause analysis is
- 2:02effective in preventing the recurrence of adverse events.
- 2:07And although early studies suggested that Rcas are
- 2:10effective in promoting ideas for preventing recurrence, more
- 2:14recent studies don't confirm these findings.
- 2:17Put simply, we're not seeing stronger or more consistent
- 2:20evidence that RCA processes are actually help prevent future
- 2:24harm. Further in the details, in only
- 2:27two studies could it be established that Rcas
- 2:30contributed to the improvement of patient care to some extent.
- 2:34And these two studies were themselves limited by the number
- 2:37of the Rcas reviewed, really weakening the evidence overall.
- 2:41Also, they found in 50% of the cases the recommendations from
- 2:45the Rcas were quite weak, which didn't lead to a reduction of
- 2:49adverse events. So half of the time the outputs
- 2:54from the Rcas aren't even strong enough to really have any
- 2:57tangible improvements of the things they're supposed to
- 2:59actually help prove. They also found that the action
- 3:01plans saw the corrective actions are really poorly designed and
- 3:04untested. One study found that action
- 3:07plans didn't follow any controlled implementation
- 3:09pattern, so no link could be established between the plans
- 3:13and actual tangible operational improvements.
- 3:16Put simply, the fixes that result from these RCA processes
- 3:20may be too flawed or too poorly implemented to really help
- 3:23improve operational outcomes, and maybe they can even create
- 3:27some new ones. Also, they found that most of
- 3:30the recommendations ignored deeper systemic issues.
- 3:34For instance, most of the proposed recommendations focused
- 3:37on active errors from people and neglected latent contributing
- 3:42factors. So the focus on people provides
- 3:45maybe short term solutions, but really only partially helps to
- 3:49avoid future problems. It's not really improving the
- 3:51conditions that people work in. So instead of addressing system
- 3:54flaws, these RCA processes, according to this research,
- 3:59often results in blaming frontline staff of a really
- 4:01shallow solutions. They also found there was a
- 4:05strong lack of follow up and verification of the
- 4:07improvements. So the RCA processes didn't
- 4:10really require any cheques to see whether the improvements
- 4:13were actually carried out. This disconnect undermines A
- 4:17usefulness. Without follow up, even good
- 4:20recommendations can fail. Not surprisingly, back down that
- 4:24there was quite low involvement from those closest to the
- 4:26incident. So managers and personnel
- 4:28involved in the actual adverse events had low participation
- 4:31rates in the investigation teams.
- 4:33This limited not only their insight into what was actually
- 4:36happening, but also reduced potential psychological recovery
- 4:40for second victims and those emotionally affected by the
- 4:43incident. Put another way, leaving out
- 4:46frontline staff leads to weaker analysis and missed chances for
- 4:49healing and improving. And they found that blame
- 4:53culture really discourages reporting and RCA participation.
- 4:58So they found cultures that they were really focused on searching
- 5:01for guilty party, those responsible.
- 5:04And this created tensions in the work environments that really
- 5:06challenged interprofessional relationships.
- 5:09His fear and lack of trust LED professionals to refuse to even
- 5:12participate in the incident processes.
- 5:15Simply put, if people fear punishment, they won't speak up.
- 5:19So in conclusion, Rcas well may be useful for some things can
- 5:25really lead to very remote and immediate fixes, but they don't
- 5:29seem to be very effective for long term or effective
- 5:32implementation measures to prevent the reoccurrence of
- 5:35incidents. And although some studies have
- 5:38demonstrated the usefulness of Rcas and in the recommendations,
- 5:42most of the published studies in at least in this study in
- 5:45healthcare found that just over half of the recommendations
- 5:48weren't even useful enough to prevent the same incidents from
- 5:51recurring in the future. They were disconnected from the
- 5:54things that they were supposed to be focusing on and fixing.
- 5:57So they conclude that RCA approaches can potentially help
- 6:01understand some contributing factors, but they often failed
- 6:04to help with the fixes or fix the issues.
- 6:07In contrast, the fixers tend to be really weak, shallow, or even
- 6:11I'll suited to improve these complex environments like
- 6:14healthcare. So what do we make of these
- 6:17findings? Well, again, it's not one tool.
- 6:20RCA covers a lot of ground. In any case, I think we really
- 6:25need to be clear around on what we want the RCA processes to
- 6:28achieve, can achieve, should achieve and evaluate whether our
- 6:32processes are configured for those results.
- 6:35Do we have any unfair expectations or unrealistic
- 6:38expectations around what we want them to be able to achieve?
- 6:41Do we even have the right resources and expertise?
- 6:43Maybe a shake up is needed. Do we need less investigations
- 6:47and maybe more proactive learning?
- 6:49Do we need better feedback and engagement channels with workers
- 6:52or design level interventions? What about different teams being
- 6:55involved or trying different tools and approaches?
- 6:59And maybe instead of building a shopping list of contributing
- 7:01factors and detailed timelines that will benefit few, maybe
- 7:06spend more time on learning about daily work, the
- 7:09constraints and designing in better, safer work.
- 7:13Importantly, work that I covered previously from Lundberg
- 7:17suggested that investigations, probably like most processes in
- 7:21organisations, are affected by a host of sociopolitical factors
- 7:25separate to the incident itself, but still significantly impact
- 7:29what investigations find they construct and ultimately try and
- 7:32fix. Maybe to a degree some of these
- 7:36constraints are just fundamental limits within organisations.
- 7:39So for limitations there was a few, but I think the main 1
- 7:42really is there's a relatively limited body of evidence on Rcas
- 7:48and how what they actually change in occupational settings,
- 7:52also unlike a broken record. But there's also the issue with
- 7:56using statistically rare events like incidents.
- 7:59It's a huge limitation. It's just really difficult to
- 8:02connect upstream factors with downstream outcomes.
- 8:06However, a number of other healthcare RCA studies using
- 8:10different measures like corrective action quality also
- 8:14find widespread and systemic issues with the RCA approaches.
