Aim: The purpose is to study, analyze and improve various healthcare parameters like TAT (turnaround time), chair side time, waiting time etc with reference to dental care at a select hospital in Hyderabad city. Materials and Method: Before the start of the actual study a pilot study has been done taking 20 outpatients coming to hospital in month of May 2015. Later actual study was done for one month from 6th June 2015 to 6th July 2015. Data collection sheet has been circulated among 30 patients for 6 days with a total sample size of 180 patients. DMAIC process of Six Sigma is taken into consideration to reduce turnaround time which includes the tools like SIPOC (Supplier, Input, Process, Output and Customer), Process analysis flow diagram, fishbone diagram, benchmarking, value Stream Mapping (VSM), box plot and Pareto analysis. Capability rates (Cp, Cpk) as performance measures between baseline and improved data. P value <0.05 is considered as significant value. After implementation of suggestions, again same sample of 180 respondents were analyzed by application of tools in improve phase which shows that there is an improvement in TAT. Results: The average turnaround time in the present study by application of six sigma methodology, per patient decreased from 3.11±1.06hours (186.6±63.6 minutes) to 1.989± 0.116 hours (119.34±6.96minutes) after implementation of six sigma process with its tools. Estimate for difference is 1.1224. P-Value is found to be highly significant with p= 0.000. Conclusion: Six sigma is a scientific approach to excel business. Six sigma strategies can be successfully utilized in almost all organizations to remove the obstructions in the success of the organizations as well as to improve customer satisfaction. In present study there is an increase in outpatients which lead to customer satisfaction and increase in profit of organization.
