Summary

The proposed 600,000 population model for vascular services is feasible in urban areas but may reduce access in remote regions. Further analysis is needed for geographically diverse populations.

Area of Science:

  • Health Services Research
  • Vascular Surgery
  • Health Policy

Background:

  • Criticism of current vascular service delivery models.
  • Proposal for re-organizing vascular services based on a 600,000 population catchment.
  • Need to assess the feasibility of this model in diverse geographical settings.

Purpose of the Study:

  • To evaluate the feasibility of a 600,000 population model for vascular services.
  • To assess the impact of this model on population access to vascular units across different English regions.

Main Methods:

  • Analysis of surgical arterial activity data (Hospital Episode Statistics 1994/95).
  • Postal survey of acute Trusts to determine vascular facilities and staffing.
  • Geographical Information System (GIS) mapping to calculate population proximity to vascular units.

Main Results:

  • Only 38% of Trusts performed over 100 arterial procedures annually; 22% had a dedicated vascular on-call rota.
  • The 600,000 population model could increase the proportion of the population living >40 km from a vascular unit by 16.5% in East Anglia.
  • Impact on access was negligible in Wessex (0.4% increase) and North West Thames.

Conclusions:

  • The 600,000 population model for vascular services shows potential feasibility in urbanized areas.
  • Geographically remote regions may face challenges with accessibility under this proposed model.
  • The model's suitability is dependent on regional geographical characteristics and existing service distribution.
