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

OBJECTIVES: evaluation of a centralised collection of clinical data (Service) within @entity5 screening programmes in Piedmont based on a hub_spoke model and its impact on process indicators. DESIGN: assessment of an organisational intervention, through a non-controlled pre-post design. SETTING AND @entity1 : organised screening programmes within the Piedmont Region, divided into 9 departments. MAIN OUTCOME MEASURES: clinical data (extracted from medical charts for mammography screening and from excision histology reports for cervical screening) obtained through the Service were quantified and their completeness was assessed. The Service impact on the detection rate (DR) was evaluated, comparing the DR pre- (2005-2008) and post-Service (2009- 2012) within breast screening; 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 @entity1 resources employed in pre- and post-Service periods were reported. RESULTS: 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 @entity5 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 @entity1 . The system centralisation did not imply an increase in the dedicated personnel. CONCLUSION: the Service is an operational core which coordinates the collection of clinical data, impacting on process indicators without an increase in @entity1 resources at departmental level.
