Patient Satisfaction & Experience

NPS: Net Promoter Score

The Net Promoter Score is a simple one question survey that asks, on a scale of 0 to 10, how likely are you to recommend a product or service (in this case your practice) to a friend or colleague. It was developed and trademarked by Bain & Company. Those who respond 9 or 10 are termed promoters who are likely to recommend and evangelize your service to other people. Those who respond 7 or 8 are termed passives who are likely to be somewhat satisfied and probably wouldn’t spread negative word-of-mouth but are unlikely to promote your service. Those who respond 6 or lower are termed detractors – these are people who are not particularly happy with the service, are unlikely to return and may spread negative word of mouth. Your Net Promoter Score is derived by subtracting the percentage of Detractors from the percentage of Promoters and thus can range from -100 (everyone person surveyed is a detractor) to 100 (everyone is a promoter). If you had an equal split between the three groups, you would get a score of 0.

PSQ-18: Patient Satisfaction Questionnaire

The Patient Satisfaction Questionnaire 18 is a short form version of the original 80-item PSQ developed by the RAND Corporation. It measures patient satisfaction across 7 different scales – General Satisfaction, Technical Quality, Interpersonal Manner, Communication, Financial Aspects, Time Spent with Doctor and Accessibility and Convenience.
