Key result
Swedish Perioperative Register validation shows ~100% surgical data accuracy and dramatic elective surgery declines during COVID-19.
Why the study?
The Swedish Perioperative Register (SPOR) collects extensive national surgical data, but validation of data mapping and demonstration of its utility were needed.
Observational (n=4,000,000)
Yes
The Swedish Perioperative Register is a valid tool with high data accuracy for tracking surgical procedures, useful for monitoring national surgical capacity during crises like the COVID-19 pandemic.
SPOR shows high procedural data accuracy; leaves open broader perioperative research use until missing quality measures are addressed.
BACKGROUND: Since 2013 surgical units in Sweden have reported procedures to the national Swedish Perioperative Register (SPOR). More than four million cases have been documented. Data consist of patient ID, type of surgery, diagnoses, time stamps during the perioperative process (from the decision to operate to the time of discharge from the postoperative recovery area) and quality measures. This article aims to describe SPOR and validate data mapping. Also, we wished to illustrate the utility of the SPOR in assessing variations in national surgical capacity during the COVID-19 pandemia years 2020-2021. METHODS: After a detailed description of SPOR, we report on the validation of data performed by comparing data from local databases with data stored in the central SPOR database, assessing missing values and accuracy. Effects of the pandemic on surgical capacity were described by developing an index, based on the number of performed surgical procedures per week during four production weeks in January 2020. Subsequent weeks were then compared with this baseline. RESULTS: The validation effort demonstrated nearly 100% data accuracy for the number and type of surgical procedures between local and central data. Missing data was a problem for some parameters. The number of performed surgical procedures decreased dramatically from week 11 in 2020 compared with normal production on a national basis, mainly impairing elective surgery. DISCUSSION: Data validation revealed good agreement between local and central databases. The changes in national surgical capacity during the pandemic were illustrated by an index based on the reported surgical production.

Holmström et al. (2022) conducted an observational in Surgical procedures (n=4,000,000). COVID-19 pandemic vs. Pre-pandemic baseline (January 2020) was evaluated on Data accuracy for the number and type of surgical procedures between local and central data. Validation of the Swedish Perioperative Register demonstrated nearly 100% data accuracy for surgical procedures and revealed a dramatic decrease in elective surgery during the COVID-19 pandemic.
