Title: Location-allocation modelling for the geographical
distribution and organisation of health services
Speakers: Paul Harper and Honora Smith, University of Southampton, UK
----------
Abstract: Examples of geographical distribution and organisation of
health services are the location of outpatient departments within a city and
the provision of particular services such as cardiac, cleft lip and palate,
and dental services, across a region. Important issues in the provision of
services include the location of the service centres, service capacities,
geographical distribution of patients, and ease of access to the health
services. These types of geographical problem fall under the general
heading of location-allocation problems. In this talk, we review some of
the existing location-allocation literature, with particular attention given
to those within the health service domain. The development of a stochastic
geographical patient-based simulation model is described with case studies
from dental services across London, and the provision of cardiac services
across Eastern England. Finally, we discuss some future research directions
using mathematical network flow models, and collaboration with hospitals in
India, where we are hoping to evaluate options for multi-level health
services to serve millions of people over a large geographical region. The
Hospital Episodes Statistics (HES) database contains records of all admitted
patient care in NHS Trusts in England. With over 12 million records per
year, the database has information on patients (e.g. age, sex, residence),
their pathway through hospital (e.g. elective or emergency, dates in and
out) and some clinical data (diagnoses and operations). This provides a
resource for a number of central and local purposes, such as defining
activity, investigating trends, monitoring performance and managing
resources. Traditionally reported at national, Trust or health organisation
level, HES is also developing analysis at consultant level. This session
will look at what HES comprises, how it can be used and a selection of
examples of the analysis it offers.

Dr Paul Harper is a lecturer in Operational Research, School of Mathematics,
University of Southampton. His research interests include modelling for the
early detection, prevention and treatment of diseases/medical conditions
(research topics have included diabetic retinopathy, breast cancer,
colorectal cancer and HIV/AIDS) and modelling for the management of health
services (examples include hospital capacities and workforce planning). He
has worked with a number of NHS Trusts, Strategic Health Authorities and
Primary Care Trusts, and currently holds grants from EPSRC and Department of
Health.
Mrs Honora Smith is a PhD research student in Operational Research at the
University of Southampton. On completing an MSc in Operational Research, she
was inspired to continue in healthcare modelling, having worked for Wessex
Regional Health Authority back in the mists of time! She is currently
researching the mathematics of network flows and social networks with
regards to location of healthcare facilities, with particular interest in
the provision of primary health care in undeveloped rural areas.
