How to effectively analyze problems to identify the main causes that have led to them, and to initiate actions to prevent similar problems from occurring in the future. Together they form this practical mini-booklet that you can download.
It is important to remember that all documentation of an investigation may be discloseable in the event of a complaint and therefore advice should be sought from the Complaints and Legal Services Officer. The Starting PointIn the cases of complex events it may be necessary to start at the point of the adverse event occurring and work backwards, or in other cases the start point may be much clearer, i.
The approach to be taken should be decided upon by the Investigation Team. Staff should either be interviewed or asked to make a full record of the incident as soon as possible after the event, however, advice should be sought from Complaints and Legal Services Officer before writing a statement.
For further guidance on interviewing techniques please see Appendix 3. The location of the incident:If possible the investigators should visit the location where the adverse event took place and make observations about the layout, this is important in incidents involving violence and aggression. Notation of the physical locations of staff, visitors, witnesses etc should be made.
Equipment:Any equipment directly involved in the adverse event should be removed and preserved. Documentation:Guidelines, policies and procedures in place when the adverse event occurred, risk assessments, incident reports, relevant clinical audits. It is also useful to look at the context, in which the event occurred, for example, what is the custom or practice of the department?
Data-mappingIt is important to have a structured approach to managing the documentation the investigation will generate.
Capturing events in chronological order will make it easier to see the chain of events unfold. There are several common methods for mapping data including Narrative Chronology, and Diagrammatic Timelines. Narrative Chronology Example March 7 Patient seen by Consultant and placed on 10 minutes observations. Identifying ProblemsAs you map the events leading up to an incident you will naturally generate questions as to what requires further investigation.
If you find there are many issues that may require further investigation it may be necessary to prioritise these issues. One way of doing this is for the investigation team to independently undertake root cause analysis of the issues. Or you may wish to involve all the relevant staff and hold a meeting to involve the team in the root cause analysis process. The latter option is more favourable as it enables the team to take ownership of any actions arising, to foster a learning environment and allows the staff members to 'clear the air'.
Obviously this option may not always be available due to time constraints. Preparing for a Root Cause Analysis MeetingThe lead investigator for the investigation primary role is to ensure that the root cause analysis is completed in the time available, and that participants feel that the process has been worthwhile and of value.
The lead investigator has a facilitation role, maintaining a neutral stance, and only intervening to guide the participants on their journey. They are also responsible for ensuring that all participants feel free to contribute without the fear of blame being attributed.
For the meeting itself it is useful to obtain sheets of paper for the timeline, different coloured post-it notes and different colour pens.
All attendees to the meeting should be invited personally by letter or telephone and given some information as to the process. Once the meeting begins re-state the purpose of the meeting and ensure that all attendees understand that the meeting is about learning not apportioning blame.
Ensure that all attendees know who everyone else is. Structured Brain Storming is where the facilitator asks each member of the group to contribute a suggestion or idea. This is a useful approach if some members of the group are very dominant, making it difficult for other members to contribute. Unstructured Brain Storming is a 'free for all'. This enables spontaneity but can lead to ideas being lost.
The key to successful brainstorming is to focus on all members contributing their ideas, and not allowing any in-depth questioning or exploration until the process of brain storming is completed. The facilitator must also be careful to record ideas as they are spoken. Brain WritingThis is a similar technique to Brain Storming but all members are given blank post it notes and contribute ideas anonymously. This technique is useful as participants are more willing and able to share their thoughts if given the privacy to do so.
If this method is used it is important to set a time limit on the exercise and give participants enough space to enable privacy. Once the set time is up then the facilitator collects up the post it notes and notes all the ideas on the flip chart. If there are only a few issues raised then these can be explored using the Five Why's, Cause and Effect or Fishbone Diagram. However, if there are numerous issues raised the group must prioritise these and the most significant investigated.
Nominal Group TechniqueThis technique is a consensus-building tool. It can be used to assist the group in prioritising the issues they consider most significant in contributing to the event and therefore requiring root cause analysis. It can also be used to help the group decide the most fundamental root causes and to agree the priority recommendations arising from the investigation.
It is important that all participants agree that they are bound by the results of this process. Firstly problems are identified using Brain Writing or Brain Storming technique. Then all ideas are transferred to a flip chart, with issues grouped together logically and duplicates removed. Each individual idea is then given a number. Each participant is given a rank chart and asked to choose 5 issues they feel are most important and prioritise them, with number 1 being the most important issue.
The issues with the lowest scores form the list of prioritised issues for root cause analysis or the prioritised list of recommendations. When using this technique to prioritise recommendations, actions requiring additional resources or senior management support are not necessarily more important than actions that the team themselves can implement.
The Five Why'sThis technique is best suited to non-complex problems and is a basic cause and effect technique. It is important to remember that you should only undertake one 'cause and effect' at a time. If this process identifies more and more problems it may be wise to transfer to the Fishbone Diagram.
No policy or procedure in place that requires a written record being made of collections No defined process in place for securing courier vehicles Incident reporting procedures does not take into account of Police inability to given crime numbers Root CausesCourier van theft with loss of medical records Fishbone Diagram TechniqueThe Fishbone Diagram technique is useful when needing to identify the influencing factors for a number of identified problems within a range of contributory factors.
For example, the main problem to be investigated may be Theatre Delays and there may be several identified contributory factors within this. The process should not only identify negative influences but positive also. Cause and Effect ChartThis is a useful tool if you wish to view the incident as a whole, showing the chronological order of an event as well as the influencing and causal factors, with the use of standard symbols for events, changes, barriers and causal factors.
However, this method does require a lot of space and can become confusing. Firstly you must identify the adverse incident or end point and then the starting point of the incident. You must then consider all the documentation and information available in relation to what happened, when it happened, how it happened and the consequences.
You must now begin constructing the event line in chronological order. Then begin to insert secondary events and conditions at appropriate places. As you gather new information this should also be inserted into the chart.
You can now begin to identify the causal factors and failed barriers. Once these have been identified you can make identify the corrective actions needed. Problem to be investigated Barrier AnalysisBarriers are controlled measures that are put in place to prevent harm, they can be physical, natural, human action or administrative. Barrier analysis is a critical appraisal of the control measures in place in terms of their effectiveness in preventing harm. Firstly you list all the control measures barriers in place that were designed to prevent the event from occurring.
Then you evaluate each of them in turn as strong, average or weak. For the barriers that have failed you ask 'why? Human Action and Administrative barriers are usually weak as they rely upon human action, they can therefore be strengthened by additional measures such as audit. Change AnalysisChange analysis is used to identify the 'knock-on' effects that everyday changes in the healthcare environment can bring.
Firstly you map out the normal procedure that should occur without the adverse event occurring. Alongside this you map out what did actually happen resulting in the adverse event. Then you compare the two processes and identify the differences. Then you identify whether the difference, or change, had a direct impact on the adverse event occurring. Once you have identified the changes that did impact then a further analysis can be undertaken as to why the changes occurred and if necessary barrier analysis can be undertaken.
Once this process has been carried out the investigator should analyse why these changes occurred. Barrier Analysis is a useful tool at this stage, along with the Five Why's and the Fishbone. Example of Change AnalysisIn the appendices of this document are templates for different techniques used in this document.
Appendix 1Questions to assist in identifying system weaknesses 1. Was there anything about the way the team works together, or perceives each other's role that contributed to the outcome of this event?

Was there anything related to the working environment or conditions of work that contributed to this event? Was there anything relating to the communication systems, between individual staff, departments, or mechanical communications e.
Was there anything about the organisations strategy, its strategic objectives and priorities that contributed to the outcome of this event? The Interviewee's account:The interviewee will describe things from their perspective. It is important not to interrupt them at this stage, giving them time to pause for thought.
In science and engineering , root cause analysis RCA is a method of problem solving used for identifying the root causes of faults or problems. RCA generally serves as input to a remediation process whereby corrective actions are taken to prevent the problem from reoccurring. The name of this process varies from one application domain to another.
Cause analysis tools are helpful tools for conducting a root cause analysis for a problem or situation. They include:. Fishbone diagram : Identifies many possible causes for an effect or problem and sorts ideas into useful categories.
Root cause analysis RCA is a problem-solving process for investigating an incident, problem, concern, or a non-conformity. Finally, determine solutions to address those key points, or root causes. Root cause failure analysis uses a variety of tests to determine the true source of a product failure. Then, look at the complex systems around those problems, and identify key points of failure.
Беккеру удалось оторваться от убийцы, и он рванулся к двери. Халохот шарил по полу, нащупывая пистолет. Наконец он нашел его и снова выстрелил. Пуля ударила в закрывающуюся дверь. Пустое пространство зала аэропорта открылось перед Беккером подобно бескрайней пустыне.
Может, отключить его самим? - предложила Сьюзан. Стратмор кивнул. Ему не нужно было напоминать, что произойдет, если три миллиона процессоров перегреются и воспламенятся.
