Risk Identification.
• Training video
Risk Identification
• Risk identification is the process through which
we become aware of risks in the health care
environment that constitute potential loss
exposures for the institution.
Systems for Risk Identification
Informal Risk Identification Systems
– Claims data
– Medical record reviews
– Patient complaints
– Standardized surveys and questionnaires
– Personal inspections
– Committee minutes
– Survey or regulatory reports
– Recall notices
– Experts
Systems for Risk Identification
Formal Risk Identification Systems
– Incident reporting
– Occurrence reporting and screening
– Sentinel event tracking
– Failure mode and effect analysis
– Device reporting and tracking logs
– Security reports
Risk Identification
• Identification of risks is important but early
identification is our goal
• Early identification is important because :
1- A prompt investigation can be initiated while
information is still fresh and available.
2- An early intervention can be considered.
3- A high potentiality of eliminating or reducing the
cost of the claim.
Risk Identification
2 main methods to identify risks :
1- Incident reporting
2- Generic / Occurrence screening
Both aim at early identification of risks and
take appropriate measures to eliminate or
limit liability exposures.
Incident / occurrence Reporting
• Definition of incident: any happening that is
not consistent with the routine care of a
particular patient or an event that is not
consistent with the normal operations of a
particular organization.
• Considered as early warning system.
• The analysis result should be revised by
process owners and who have the authority
to make changes in protocols ,policies and
procedures
Content of the Incident Report
• vary in content and structure and vary
from organization to organization
• emphasis has been placed on making
forms “user friendly,”
Content of the Incident Report
Demographic information :
• including name, home address, and telephone number of the
patient, visitor, or employee involved in the incident. (For patients,
medical record numbers also may be recorded as part of the
identifying information.)
• This information is used to identify the potential claimant and
witnesses in case of litigation.
Facility-related information : such as admission or visit date, patient
identification number, patient room number, and admitting diagnosis
or presenting complaint.
This is used as aggregate data to determine whether certain units of
the system are more incident prone.
Trending this information promotes risk management intervention and
actions plan to react to frequency or severity in incidents reported.
Content of the Incident Report
Socioeconomic data : on the individual
involved in the occurrence, such as age,
gender, marital status, employment, and
insurance status.
This information aids in assessing potential
loss. For example, collecting employment
status assists the risk manager and counsel
in determining the potential for wage loss or
economic (loss of salary) damage.
Categories according to type of
event
• Medication error
• Adverse drug reaction
• Fall
• Equipment problem
• Complication related to procedure , treatment , or
test
• Transfusion event
• Behavioral problem( e.g. , assault , elopement
,etc.)
• Visitors events
• Unsafe conditions with potential for harm
Categories according to harm to
patient
• Category A: circumstances or events that have the
capacity to cause error but no error occurred.
• Category B: An error occurred but the error did not
reach the patient i.e. no harm occurred ( near
miss )
• Category C: an error occurred that reached the
patient, but did not cause patient harm.
• Category D: An error occurred that may have to or
resulted in harm to the patient and required
intervention
• Category E: an error occurred that may have to or
resulted in the patient’s death ( sentinel event )
Staff Participation in Incident
Reporting
• Incident reporting should be the responsibility of
all staff , responsibility for completing an incident
report rests with any facility staff members who
witnesses, discovers, or has direct knowledge
with the incident.
Staff Participation in Incident Reporting
Barriers How to remove
staff view reporting as a routine task or
low-priority paperwork.
1. By providing feedback on the results of
investigation and problem resolution
2. Trending and analysis reports that lead
to changes in protocol, procedures, or
equipment based on these findings
fear the report is an admission of
negligence that exposes them to liability
and could be used against them in court
or for a punitive measure
1. incident report is not used as either a
punitive measure in disciplining
employees or a vehicle for airing
interpersonal disagreements.
2. The event itself may require disciplinary
action but not through the incident
reporting process
3. Training must stress that the report
should be a factual account of what
happened; no finger-pointing . Incident
reports are meant to collect “just the
facts,” .
Staff Participation in Incident
Reporting
Why incident reports may not be filed when policy directs staff to
do so ?
• Observer is too busy to complete the report when a narrative
section is required.
• Staff believe that reporting is of little value due to lack of
feedback.
• Staff fear disciplinary action based on the report.
• Non-physicians are reluctant to report incident involving
physicians.
• Staff are concerned that the report may lead to a lawsuit
leading to personal responsibility.
• Staff failed to recognize that an incident occurred.
• Staff do not understand the definition of an incident.
Occurrence Screening
• This system, utilizes a clearly defined list of patient
occurrences with which patient medical records are screened.
• It’s an example of 100% review system ,
• The screeners are looking for deviations from practice, policy,
and procedures.
• Criteria for the screens are established in areas that are
considered to be either :
1. high risk.
2. have a high number of incidents that have been reported
as quality of care “red flags” to be further evaluated.
3. areas where the effects of an untoward event occurring
can have disastrous results from an injury standpoint.
As an example :inappropriate informed consent documentation
Occurrence Screening
• In an inpatient setting, all patient records are
reviewed against the criteria within forty-eight to
seventy-two hours of admission and every three or
four days thereafter until the patient is discharged.
• The patient chart also is reviewed approximately
two weeks after discharge to ensure that
compliance with all criteria has been assessed.
• Results of this screening process are prepared for
each admission by trained data retrieval personnel
(screeners).
Occurrence Screening
• The abstract is then forwarded to the quality
improvement office for follow-up.
• When identified, serious occurrences are
reported immediately by the patient care
reviewers to the appropriate person for
action.
• All occurrences are aggregated to aid in
identifying any trends that reflect patient care
problems requiring remedial action.
• It’s concurrent (may be retrospective review).
Sentinel event
• an unexpected occurrence involving death or serious
physical or psychological injury.
• Serious injury includes loss of limb or function.
• Death or major permanent loss of function (sensory,
motor, physiologic, or intellectual), suicide, rape,
hemolytic transfusion reaction, Surgery/procedure on
the wrong patient or wrong body part, infant
abduction or infant discharge to the wrong family.
Response to sentinel event
Root cause analysis
Sentinel Events
• Rosie King’s video
Root Cause Analysis
• Is a process done in response to
occurrence of sentinel event or near miss.
• The aim of root cause analysis is to
conduct intensive analysis to reach the
embedded problems in the system and
solve it.
RCA- Sequential steps
1- Define the problem
• Ask what is wrong, what is involved: conditions, activities,
materials.
• Ask when: day ,date, time, shift, time pattern, schedule.
• Ask where: site, area department, physical environment,
step in process.
• Ask how the what or who is affected, how much, how many,
work practice, omission / commission.
• Ask who is involved: patients, caregivers, other staff,
vendors, visitors.
• Review relevant documents.
• Consider other data collection options: surveys, observations,
interviews.
RCA- Sequential steps
2- perform task / process analysis
• divide a process into steps by sequencing
actions, instructions, conditions ,tools ,
and materials associated with the
performance of the task (flowchart).
• learn exactly what was supposed to
happen.
• contrast the baseline with what actually
happened (based on initial data
collection).
RCA- Sequential steps
3- perform change /different analysis:
• compare the task /steps successfully
performed to the same task /steps when
unsuccessful.
• analyze the difference.
• describe for each difference its effect on
the situation.
RCA- Sequential steps
4- perform control barriers/ safe guard analysis:
• analyze safeguards needed to prevent the event.
• analyze missing or ineffective safeguards.
Safeguards may be :
 physical: safety equipment and devices; locks, walls.
 Natural: distance and time (limited exposure).
 information: caution such as labels , alarms.
 knowledge: making information constantly available.
 administrative: safety policies and procedures,
regulations, supervisory practices, training, education,
communication process.
RCA- Sequential steps
5- Begin cause and effect analysis
• List each undesirable step of the
occurrence
• considering each a primary effect
• using data collected to date , determine
what causes allowed or forced each effect
to occur
• show the relationship between each
cause and effect
RCA- Sequential steps
• continue the cause and effect analysis until :
 Cause is outside the organization control
to correct.
 Primary effect is fully explained.
 No other causes can be found to explain
the effect.
 Further analysis will yield no additional
benefit in correcting the problem.
• List all validated causes.
Healthcare FMEA Definitions
Healthcare Failure Mode & Effect
Analysis (HFMEA):
(1) A prospective assessment that
identifies and improves steps in a
process thereby reasonably ensuring
a safe and clinically desirable
outcome.
(2) A systematic approach to identify and
prevent product and process problems
before they occur.
Healthcare FMEA Definitions
Effective Control Measure:
A barrier that eliminates or substantially
reduces the likelihood of a hazardous
event occurring.
Healthcare FMEA Definitions
Hazard Analysis:
The process of collecting and evaluating
information on hazards associated with
the selected process. The purpose of
the hazard analysis is to develop a list
of hazards that are of such significance
that they are reasonably likely to cause
injury or illness if not effectively
controlled.
Healthcare FMEA Definitions
Failure Mode:
Different ways that a process or sub-
process can fail to provide the
anticipated result.

2 tools to identify and control patient safety risks

  • 1. Tools to Identify and Control Patient Safety Risks Dr. Mohamed Mosaad Hasan CQI/ PS Specialist
  • 3. Risk Identification • Risk identification is the process through which we become aware of risks in the health care environment that constitute potential loss exposures for the institution.
  • 4. Systems for Risk Identification Informal Risk Identification Systems – Claims data – Medical record reviews – Patient complaints – Standardized surveys and questionnaires – Personal inspections – Committee minutes – Survey or regulatory reports – Recall notices – Experts
  • 5. Systems for Risk Identification Formal Risk Identification Systems – Incident reporting – Occurrence reporting and screening – Sentinel event tracking – Failure mode and effect analysis – Device reporting and tracking logs – Security reports
  • 6. Risk Identification • Identification of risks is important but early identification is our goal • Early identification is important because : 1- A prompt investigation can be initiated while information is still fresh and available. 2- An early intervention can be considered. 3- A high potentiality of eliminating or reducing the cost of the claim.
  • 7. Risk Identification 2 main methods to identify risks : 1- Incident reporting 2- Generic / Occurrence screening Both aim at early identification of risks and take appropriate measures to eliminate or limit liability exposures.
  • 8. Incident / occurrence Reporting • Definition of incident: any happening that is not consistent with the routine care of a particular patient or an event that is not consistent with the normal operations of a particular organization. • Considered as early warning system. • The analysis result should be revised by process owners and who have the authority to make changes in protocols ,policies and procedures
  • 9. Content of the Incident Report • vary in content and structure and vary from organization to organization • emphasis has been placed on making forms “user friendly,”
  • 10. Content of the Incident Report Demographic information : • including name, home address, and telephone number of the patient, visitor, or employee involved in the incident. (For patients, medical record numbers also may be recorded as part of the identifying information.) • This information is used to identify the potential claimant and witnesses in case of litigation. Facility-related information : such as admission or visit date, patient identification number, patient room number, and admitting diagnosis or presenting complaint. This is used as aggregate data to determine whether certain units of the system are more incident prone. Trending this information promotes risk management intervention and actions plan to react to frequency or severity in incidents reported.
  • 11. Content of the Incident Report Socioeconomic data : on the individual involved in the occurrence, such as age, gender, marital status, employment, and insurance status. This information aids in assessing potential loss. For example, collecting employment status assists the risk manager and counsel in determining the potential for wage loss or economic (loss of salary) damage.
  • 12. Categories according to type of event • Medication error • Adverse drug reaction • Fall • Equipment problem • Complication related to procedure , treatment , or test • Transfusion event • Behavioral problem( e.g. , assault , elopement ,etc.) • Visitors events • Unsafe conditions with potential for harm
  • 13. Categories according to harm to patient • Category A: circumstances or events that have the capacity to cause error but no error occurred. • Category B: An error occurred but the error did not reach the patient i.e. no harm occurred ( near miss ) • Category C: an error occurred that reached the patient, but did not cause patient harm. • Category D: An error occurred that may have to or resulted in harm to the patient and required intervention • Category E: an error occurred that may have to or resulted in the patient’s death ( sentinel event )
  • 14. Staff Participation in Incident Reporting • Incident reporting should be the responsibility of all staff , responsibility for completing an incident report rests with any facility staff members who witnesses, discovers, or has direct knowledge with the incident.
  • 15. Staff Participation in Incident Reporting Barriers How to remove staff view reporting as a routine task or low-priority paperwork. 1. By providing feedback on the results of investigation and problem resolution 2. Trending and analysis reports that lead to changes in protocol, procedures, or equipment based on these findings fear the report is an admission of negligence that exposes them to liability and could be used against them in court or for a punitive measure 1. incident report is not used as either a punitive measure in disciplining employees or a vehicle for airing interpersonal disagreements. 2. The event itself may require disciplinary action but not through the incident reporting process 3. Training must stress that the report should be a factual account of what happened; no finger-pointing . Incident reports are meant to collect “just the facts,” .
  • 16. Staff Participation in Incident Reporting Why incident reports may not be filed when policy directs staff to do so ? • Observer is too busy to complete the report when a narrative section is required. • Staff believe that reporting is of little value due to lack of feedback. • Staff fear disciplinary action based on the report. • Non-physicians are reluctant to report incident involving physicians. • Staff are concerned that the report may lead to a lawsuit leading to personal responsibility. • Staff failed to recognize that an incident occurred. • Staff do not understand the definition of an incident.
  • 17. Occurrence Screening • This system, utilizes a clearly defined list of patient occurrences with which patient medical records are screened. • It’s an example of 100% review system , • The screeners are looking for deviations from practice, policy, and procedures. • Criteria for the screens are established in areas that are considered to be either : 1. high risk. 2. have a high number of incidents that have been reported as quality of care “red flags” to be further evaluated. 3. areas where the effects of an untoward event occurring can have disastrous results from an injury standpoint. As an example :inappropriate informed consent documentation
  • 18. Occurrence Screening • In an inpatient setting, all patient records are reviewed against the criteria within forty-eight to seventy-two hours of admission and every three or four days thereafter until the patient is discharged. • The patient chart also is reviewed approximately two weeks after discharge to ensure that compliance with all criteria has been assessed. • Results of this screening process are prepared for each admission by trained data retrieval personnel (screeners).
  • 19. Occurrence Screening • The abstract is then forwarded to the quality improvement office for follow-up. • When identified, serious occurrences are reported immediately by the patient care reviewers to the appropriate person for action. • All occurrences are aggregated to aid in identifying any trends that reflect patient care problems requiring remedial action. • It’s concurrent (may be retrospective review).
  • 20. Sentinel event • an unexpected occurrence involving death or serious physical or psychological injury. • Serious injury includes loss of limb or function. • Death or major permanent loss of function (sensory, motor, physiologic, or intellectual), suicide, rape, hemolytic transfusion reaction, Surgery/procedure on the wrong patient or wrong body part, infant abduction or infant discharge to the wrong family.
  • 21. Response to sentinel event Root cause analysis
  • 22. Sentinel Events • Rosie King’s video
  • 23. Root Cause Analysis • Is a process done in response to occurrence of sentinel event or near miss. • The aim of root cause analysis is to conduct intensive analysis to reach the embedded problems in the system and solve it.
  • 24. RCA- Sequential steps 1- Define the problem • Ask what is wrong, what is involved: conditions, activities, materials. • Ask when: day ,date, time, shift, time pattern, schedule. • Ask where: site, area department, physical environment, step in process. • Ask how the what or who is affected, how much, how many, work practice, omission / commission. • Ask who is involved: patients, caregivers, other staff, vendors, visitors. • Review relevant documents. • Consider other data collection options: surveys, observations, interviews.
  • 25. RCA- Sequential steps 2- perform task / process analysis • divide a process into steps by sequencing actions, instructions, conditions ,tools , and materials associated with the performance of the task (flowchart). • learn exactly what was supposed to happen. • contrast the baseline with what actually happened (based on initial data collection).
  • 26. RCA- Sequential steps 3- perform change /different analysis: • compare the task /steps successfully performed to the same task /steps when unsuccessful. • analyze the difference. • describe for each difference its effect on the situation.

Safeguards may be :  physical: safety equipment and devices; locks, walls.  Natural: distance and time (limited exposure).  information: caution such as labels , alarms.  knowledge: making information constantly available.  administrative: safety policies and procedures, regulations, supervisory practices, training, education, communication process.
