Aim: This research focuses on studying the association between workplace efficiency and customer satisfaction in tertiary hospitals of Punjab. Material and Methods: Study to find efficiency was conducted with the help of data envelopment analysis. Data envelopment analysis focuses on finding efficiency through input /output-based model which follows linear mathematical formulas. Demand of health services are increasing but availability of health services is still big issue. In that case, it will become very important for hospitals to optimally utilize their existing resources with proper efficiency measurements. Hospitals of different sizes are selected and size is dependent upon bed strength of hospitals. Results: Result explains that efficiency is considered to be negative moderator between relation of number of specialized doctors and patient satisfaction. Conclusion :Results in research suggested that higher level of efficiency level of hospitals lessen the positive effect of specialized doctors on patient satisfaction In this study medical hospital efficiency applies a negative control between accessibility of specialists and patient satisfaction,. This study gives the proof that medical hospital size has a critical negative impact on efficiency of hospital i.e. Present research indicates that smaller hospitals have a higher level of efficiency than larger and medium-size hospitals, smaller size hospitals average efficiency is .80. The average efficiency of medium size hospitals is .75 and the large hospital is .71.
