Abstract

Pathology services are increasingly recognized as key to effective healthcare delivery - underpinning diagnosis, long-term disease management and research. To the extent that pathology services affect a patient's treatment pathway, significant healthcare costs are influenced directly by the performance of these services. Given pressures on the UK Department of Health to make efficiency savings and that little is known about the efficiency of pathology laboratories, this area offers unlocked potential for efficiency gains. We adopt a time varying inefficiency model, with laboratory-specific time paths for inefficiency, to identify potential savings in pathology services based on a panel of 57 English laboratories over a 5 year period. We apply a range of approaches to account for observable and unobservable heterogeneity between laboratories. We find potential efficiency savings of 13% in pathology services in this sample, which implies the potential for an annual saving of £390m in pathology across the NHS. Our study also provides valuable insights into the impact of a range of factors influencing laboratory costs.
