Estimated percentage of the population covered by the data source in the catchment area

100% of the population of the Wellbeing services county of Southwest Finland (Varha) needing specialized or emergency health care.

Description of the population covered by the data source in the catchment area whose data are not collected (e.g., people who are registered only for private care)

Everyone in Finland is entitled to the public healthcare. Number of people/amount of data not included in our collections is next to none, so not scientifically/statistically significant.
Comment to question 9) ACI's Analytical Data warehouse from which the OMOP CDM has been extracted, was established in 2014. The actual patient data records are much older, some from 1986 onwards, most from 2004 onwards.
Comment to question 26 and 28) We can not make a difference between preterm and term newborn infants.
Comment to question 27) There are approximately 268,000 patients who are alive and have an event in the CDM data within a period of one year, counting backwards from today. This is our best estimate of the number of active patients. Our hospital treats approximately this number of patients yearly.
Comments to question 46) Data is available for medicines prescribed, coded in ATC and Vnr. Route of administration is also in structured format. Indication is not specifically recorded, but in previous studies we have attempted to deduce it based on relevant ICD10 diagnoses marked near the prescription date. Strength is available. For inpatient (=hospital-administered) drugs, dose is available but the format varies: If the dose is always the same, then it is available in structured format. If the dose varies, it is usually written in free-text format. If the dose is specifically calculated based on patient’s surface area (chemotherapy), it is available in structured format. For outpatients drugs, the dose is always in free-text format.
We are currently working on extracting structured information from free-text drug dosage data. These developments would allow us and our FinOMOP partners to compute the duration of treatment as well as the total daily dose.
The duration of treatment is simpler to deduce for inpatient drugs. We know the drug ends at least when the patient leaves the hospital, even if the prescription is left unclosed (which it often is). For IV chemothera
