  1. 1. SPACER-DEA study Electronic Prescribing Medicine Administration (EPMA) Dr. Konstantinos Petridis Dr. Prasanta Kumar Dey
  2. 2. Introduction Methodology Mathematical formulation Illustrative example Implications Next steps Outline
  3. 3. Introduction Electronic Prescribing Medicine Administration (EPMA) aims to change the medication processes change procedures at Birmingham Children’s Hospital
  4. 4. Methodology EPMA will affect the processes/groups/departments with respect to the following aspects: Technology Organizational Structure Processes Culture
  5. 5. Methodology Business sciences may look at these four aspects (Technology, Organisational Structure, Processes, Culture) Data Envelopment Analysis (DEA) technique will help us understand some of the effects of EPMA including efficiency, resources etc.
  6. 6. Methodology Based on certain assumptions, observed correspondences of inputs and outputs are used to construct potentially feasible, even if not observed, input-output correspondences. Inputs Outputs Process Efficiency
  7. 7. Methodology Inputs Outputs . . . . . Technology OrganizationStructure Process Culture Process (P2) Process (P1) Process (Pn)
  8. 8. Methodology Process (P1) Inputs Pn P2 . . . . . Outputs Pre-Implementation Process (P1) Inputs Pn P2 . . . . . Outputs Post-Implementation
  9. 9. Mathematical Formulation Maximize efficiency s.t. Inputs (staff time, cost, etc) Outputs (Patient satisfaction, Service level, productivity etc)

  15. 15. Branch 5 is efficient (θ*=1) whereas Branch 3 is not (θ*=0.869) The results of the lambda values indicate which Branch is the benchmark; to which Branch(es) the current Branch under investigation is referring as being better that it. Illustrative example (interpretation)
  16. 16. Implications Using the proposed methodology->tangible results of the efficiency of each process before and after EPMA Identify non-efficient units Examine in micro-detail the currently available data as a source to feed the DEA methodology.
  17. 17. Next steps Some of the DMUs are: Prescribe: prescribing in the Liver unit Supply: BCH dispensary Administration: Administration of medicines in Ward 8 Explore Take some measurements of the DMUs identified Efficiency measurement of these DMUs for the specific phase of the SPACER time.
  18. 18. Next steps
