[Introduction of a centralised system (Service) for collecting clinical data in cancer screening programmes in Piedmont (Northern Italy): a pre-post assessment of a hub&spoke model].

evaluation of a centralised collection of clinical data (Service) within cancer screening programmes in Piedmont based on a hubs the DR was computed through histological diagnosis made during colposcopy (pre-Service method) or through the worst diagnosis between the latter and that reported from excision histology (post-Service method) within cervical screening (data available for department 1, year 2013). Some hints on human resources employed in pre- and post-Service periods were reported.within mammography screening, the Service obtained 53.1% of extra-department medical charts and 45.8% of extra-region ones; the percentage of missing diagnoses changed from 5.5% (pre- Service) to 3.7% (post-Service). The age standardised DR for malignant tumours in the post-Service period is 1.3 times the DR of the pre-Service period per 1,000 screening tests. Within cervical screening, 51.7% of histological reports was recorded. Crude DR for high-grade lesions changed from 3.9 (pre-Service) to 4.7 (post-Service) per 1,000 screened women. The system centralisation did not imply an increase in the dedicated personnel.the Service is an operational core which coordinates the collection of clinical data, impacting on process indicators without an increase in human resources at departmental level.
