Purpose of the NPSA

Special health authority with mandate to:

  • implement a national reporting system for patient safety incidents
  • collect and appraise information to promote patient safety
  • provide advice and guidance and monitor its effectiveness
  • promote research which contributes to patient safety
  • report and advise Ministers on matters affecting patient safety
overview
Overview
  • The National Reporting and Learning System
  • The Patient Safety Observatory: what is it and why do we need it?
  • The Observatory work programme
the national reporting and learning system nrls
The National Reporting and Learning System (NRLS)
  • Confidential reporting database
  • Incidents are reported electronically – 99% come from Local Risk Management System
  • Analysis of data at national level to
    • identify trends and patterns
    • provide feedback for local action
    • inform NPSA work programmes
approaches to analysis of nrls data
Approaches to analysis of NRLS data
  • Routine monitoring reports
  • Thematic analysis
  • Ad hoc analysis
  • Exploratory
    • Reviews of selected incidents
    • Data mining
routine and thematic reports
Routine and thematic reports
  • Trust feedback reports
  • Quarterly overview
  • Thematic reports
ad hoc analysis
Ad hoc analysis
  • Requests from NHS clinicians and risk managers, and relating to current NPSA projects
  • Use of categorical data supplemented by sophisticated text searching tool
  • Examples during one week:
    • epidurals, following fatal incident, to inform an NPSA fast track project on epidural infusions
    • chairs, for an external enquiry
    • Midwifery and Obstetrics, for Litigation Authority event on maternity risk management
    • screening tests for Down's Syndrome, following software issue identified in a trust
    • systemic dermatology treatments
    • blood glucose monitors, following issue identified by the regulator for medical devices
    • wrong route administration of oral liquid medicines, to support the preparation of a patient safety alert
systematic review of incidents
Systematic review of incidents
  • Richness of NRLS data in free text descriptions review from clinical perspective adds value
  • Huge volumes of data – sampling by specialty and incident type
  • Tools to support robust and consistent review of data supported by guidance decision tree for follow-up action
data mining

Data-mining

Pattern-search

Looking for small localised patterns in the data

Able to look through high-dimensional data (categorical and free text)

Able to pick out small unknown patterns that may represent a trend in patient safety

Model building and hypothesis testing

why do we need a pso
Why do we need a PSO?
  • Incident data not the only source
  • Systematic surveillance and analysis of NRLS and other data
settings of incidents reported to the nrls
Settings of incidents reported to the NRLS

Source: Reports in the NRLS database up to 31 March 2006

the patient safety observatory at work mri scanners
The Patient Safety Observatory at Work : MRI scanners
  • NRLS data: 500 reports; 31 related to implants; five pacemakers, one implantable defibrillator, one heart valve and three aneurysm clips went undetected
  • PSO: Litigation relating to pacemaker/MRI fatality; 200 incidents reported to medical device regulator; local visits:
  • frontline staff depending on constant vigilance rather than safer systems
  • Prioritisation process: report to NPSA Board this month
pso at work collaboration with other organisations
PSO at work: collaboration with other organisations
  • Hospital episode statistics – developing patient safety indicators based on AHRQ
  • Clinical negligence: NHS Litigation Authority and medical negligence organisations
  • Safety culture and processes: NHS staff survey
slide19

Indicators from administrative data

  • replicate AHRQ analysis for a sub-set of indicators
  • mapping coding definitions to ICD10/OPCS4
  • age and sex standardised indicators derived at national and trust level, as per specifications
  • validation: length of stay and mortality (cases compared with matched controls)
  • comparison with US results
patient safety observatory summary
Patient Safety Observatory - summary
  • Systematic analysis
  • No one source of data is sufficient
  • Collaboration between relevant organisations
  • Results:
    • Investigating and reporting back
    • Better use of existing data
    • Path to integrated approach to patient safety surveillance
