Title:NHIF Bulgaria: Expenditures and Patient Counts for Antineoplastic and Coagulopathy Medicines in Hospital Treatment(🇧🇬 ИЗВЪН СТОЙНОСТТА НА КП/АПР – Приложение 2)



Summary:This dataset contains detailed records of hospital-based expenditures and patient counts for antineoplastic (anti-tumor) medicines and medicinal products for congenital coagulopathies, reimbursed outside the value of clinical pathways or ambulatory procedures (КП/АПР) by the National Health Insurance Fund (NHIF) in Bulgaria.

The data corresponds to Application 2 of NHIF’s official reporting and provides insight into high-cost therapies administered in hospital settings across the country.



Key Characteristics:





Aggregated by hospital within Regional Health Insurance Offices (RZOK).




Linked to NHIF reimbursement codes and ICD-10 diagnosis codes.




Captures non-standard reimbursements, i.e. outside bundled pathway-based pricing schemes.



Temporal Granularity:





Data is available on a monthly basis, as indicated by the period variable.




Each row represents a hospital-level report for a specific month.





Data Cleaning and Preprocessing:

All character variables have been preprocessed with the following dplyr transformations to ensure consistency and reduce noise in downstream analyses:

mutate(across(where(is.character), ~tolower(trimws(.x)))) %>%
mutate(across(where(is.character), ~str_replace_all(.x, "[\"']", ""))) %>%
mutate(across(where(is.character), ~str_replace_all(.x, "\\\\s*\\\\s*", "\\\\"))) %>%
mutate(across(where(is.character), ~str_replace_all(.x, " - ", "-")))


This includes:





Lowercasing all strings




Trimming whitespace




Removing quotes (" and ')




Replacing multiple backslashes and redundant spacing




Standardizing " - " to "-"





Structure:





📦 Rows: 876,492
