Top Clinical Risks

Assault Choking

Falls Restraints

Suicide

Patients defaulting on care

Major permanent injury or inpatient death as a result of these incidents

Deterioration of patients’ mental health status leading to potential harm to self and others as a result of patients defaulting psychiatric clinic follow-ups

Reducing Bedtime Sedatives

*PRN is a medication that is ordered by a practitioner to be administered on an “As Needed” basis according to written parameters of a practitioner.#Sedatives is a substance that induces sedation by reducing irritability or excitement.

Focus

Target

Interventions

Sustain & Spread

Frequent usage of PRN* sedatives in Geriatric Psychiatry wards

To reduce the administration rate of PRN* bedtime sedatives** by nurses in an acute psycho-geriatric ward by 30% in 6 months.

•Make environment more conducive for sleep : change shift-handover location •Pharmacological education to enhance nurses’ understanding •Patient education to address lack of knowledge•Introduce sleep monitoring chart to track patients’ sleep patterns

Gains sustained & interventions successfully spread to another geriatric psychiatry ward

51% Reduction

Average Administration Rate of Bedtime PRN Sedatives Per Week

Focus

Target

Sustain & Spread

Tracking Discharged PatientsCare integration & treatment compliance for patients with Schizophrenia & Delusional Disorders

Increased specialist clinic attendance rate of recently discharged IMH patients by 10% in Year 1 as compared to baseline

Interventions

•Use of risk and needs assessment and stratification

•Case Management and Case Tracking

•Integrating systems (between IMH and Community Partners) through right-siting

Sharing project interventions & results with other public hospitals and community partners for spread

DETECTING HARMAdverse Events Studies

Adverse Events Studies 2007/2010 1st stage against a

list of 18 triggers (from Harvard Medical Practice Study) as flags for potential adverse events that require further review.

2nd stage by clinician on criteria positive cases to determine occurrence, disability, causation and preventability of AE

Double review for inter-rater reliability done for 10% RF1 and RF2

• Metrics/Unit of measurement o is adverse event, o measure disability as estimate of severity,o measure preventability as ascertained by clinician reviewers.

Developing a Mental Health Trigger Tool

Mental Health Trigger Tool (MHTT)

A tool to effectively Identify Harm or Adverse Events (AE) in a mental health setting and

monitor their rate over time

Most common methods of identifying and monitoring Harm or AE

Time andresourceintensive

Voluntary Reporting

Comprehensive File Review

• <20 % reported

• 90-95% no harm to patients

Is there a more efficient method?

• Global Trigger tool and Trigger tool Methodology- Developed by Institute of Health Improvement (IHI)

“ a retrospective review of randomly selected patient records using triggers (clues) to detect AE”

IHI Global Trigger Tool

Concentrate on identifying Harm or AE, not errors Only AE through acts of commission, not omission Preventability not a criterion Severity is rated based on NCC MERP index

Harm defined as “Unintended physical injury resulting from or contributed to by medical care that requires additional montioring, treatment or hospitalisation

or that results in death”

The GTT Review Methodology

• Random set of patient records• Trained Reviewers - Two Primary Reviewers - One physician Reviewer Excludes Psychiatric and Rehab Patients

Trigger Modules : • Cares (15) e.g. Transfusion of blood• Medication (13) e.g. Abrupt medication stop• Surgical • Intensive Care • Perinatal • Emergency Department

Trigger tool in Mental Health

• IHI Trigger Tool for Measuring Adverse Drug Events in a Mental Health Setting

• 30 triggers• Sodium Polystyrene Sulfonate• C. difficile Positive Stool• Vitamin K Only addresses AE due to medications Not comprehensive / specific enough May not be applicable to all mental health settings

Development of MHTT

• List of Triggers = 50 • POC Trial planned to test out the trigger

list

• A manual of triggers, their descriptions, guidelines to identify them and potential AEs were prepared

Main Challenges

• Definition of Harm or AE in Mental Health• Need to conform to IHI Trigger Tool system• Commission vs Omission events• Near Misses vs Actual Harm• Psychological harm

• Is it usable? • Does it identify triggers and harm?• Is it time and resource efficient?• Does the definition of harm requires

modification?• Does it identify harms that are clinically

important?• Can fewer triggers have the same result?• New useful triggers?

MHTT-Proof Of Concept (POC) Trial

Sample = 140 (randomly chosen files of discharged patients)

• Excluded cases = 6

Cases excluded as defined in the criteria on length of inpatient stay- > 3 days - < 90 days

• Each file reviewed by two 1st level reviewers (nurse/pharmacist)

followed by 2nd level physician reviewers• Total cases reviewed = 134

Time to review each file = 20-30 min

Post Trial – New Triggers

Incident Type New Triggers Identified that could lead to AE

Intended self harm

IM Haloperidol/ Lorazepam Concious Level Chart (CLC) Increased observation for potential suicide

(PS) after admission

Patient fall Reports of injury (Eg contusion /

haematoma) CLC

Further Development

• Consulation with Dr Carol Haraden (IHI)• Multiple rounds of further review on Trigger list through focus

group and consultation with Clinical Advisory Panel• Eliminated triggers that indicated same harm• Eliminated triggers that are unlikely to pick up serious harms• Combined triggers with common themes• Added new triggers• Renamed the triggers for easy identification---------------Current list - 26 triggers - Descriptive manual on definition and use - Consensus on Definition of Harm

Validation Study

• Sample:

• Reviewers: Each case reviewed by two non-physicians (pharmacist/nurse) and one physician (psychiatrist, registrar and above)

• Analysis: sensitivity, specificity, positive and negative predictive value of the tool.

• Inter-rater reliability between the raters

cases with AEs

cases without AEs
