Hospital productivity is a measure of efficiency, which is the total ratio of hospital output produced based on total workforce to total input used to produce this output. The hospital productivity is affected by four factors: Hospital characteristics, Service quality, Patient characteristics and Resource use efficiency. Ratio of the number of students to the number of medical and nonmedical workforce. This ratio applies to teaching hospitals that double as educational centers. Teaching hospitals generally have higher costs than nonteaching hospitals because they use funds not only for patient care but also for medical student teaching and other health services. Common indicator used for exact hospital service quality is patient survival level in the 30 days after being discharged from the hospital. Patient characteristic that has been found to strongly relate to productivity is patient age. Resource use efficiency is generally calculated by the two indicators: Daily case and elective stay ratio and Average length of stay..
