Data & Research

What data does LOSPOR collect?​

LOSPOR collects structured perioperative data entered by anaesthesiologists:

Preoperative data​

  • Patient demographics: age, sex, height, weight, BMI, blood type
  • Diagnosis (ICD-11 code + label)
  • Planned procedure
  • Comorbidities (ICD-10 codes)
  • Risk scores: ASA, RCRI, Apfel, STOP-BANG
  • Airway assessment parameters
  • Preoperative vital signs
  • Laboratory results

Intraoperative data​

  • Date, start time, end time, duration
  • Anaesthesia technique(s)
  • Airway device and tools
  • Ventilation mode
  • Monitoring modalities
  • Vascular access
  • Vital signs timetable (BP, HR, SpO₂, EtCO₂ at 5-minute intervals)
  • Drugs administered (name, dose, unit, time)
  • Continuous infusions (name, rate, start/end time)
  • Volatile agents (name, start/end time)
  • IV fluids (type, volume, start/end time)
  • Fluid balance summary
  • Patient position
  • Complications

Postoperative data​

  • Aldrete score (all five criteria + total)
  • Recovery vitals: temperature, pain NRS, PONV
  • Time in recovery room
  • Disposition: Ward / PACU / ICU
  • Handover instructions

What is NOT stored?​

The following are never uploaded or stored:

  • Patient name
  • Patient ID number / hospital file number
  • Surgeon name
  • Anaesthesiologist name (only the user account that created the record is linked)
  • Anaesthesia nurse name

When the protocol is printed, the patient's name and ID number are entered locally in the browser and printed directly — they are never sent to the server.

Anonymisation​

Each case is assigned an automatically generated case code (format: DDMMYYYY-NN). This code appears on the printed protocol and is the only identifier stored in the database.

The case is linked to a user ID (internal, not exposed in research queries) and an institution ID (anonymised as a code in research outputs).

Research access​

A LOSPOR Research Browser application is currently in development. It will provide:

  • Read-only access to the anonymised dataset
  • Filtering by procedure type, ASA class, technique, date range, institution code
  • Aggregate statistics and distributions
  • CSV export of filtered datasets

Access to the research browser will require registration and approval. Researchers will agree to data use terms before accessing the dataset.

Coming soon

The research browser is planned for release in 2026. Until then, researchers interested in the dataset may contact the LOSPOR team directly.

GDPR compliance​

LOSPOR is designed to comply with the General Data Protection Regulation (EU) 2016/679:

  • Data minimisation — only clinically necessary data is collected; patient identity is excluded
  • Purpose limitation — data is collected for clinical documentation and quality improvement
  • Storage limitation — data is stored only as long as clinically and legally required
  • Security — all data is encrypted in transit (HTTPS) and at rest (Supabase encryption)
  • EU data residency — data is stored in the EU (Supabase Frankfurt region)

Institutions self-hosting LOSPOR are responsible for their own GDPR compliance, including maintaining a Data Processing Register and notifying patients if required by local regulations.
