The ranking protocol
THE WEEK-HANSA Research Survey on India's best hospitals was conducted in 16 cities—Delhi & NCR, Lucknow, Ludhiana, Jaipur, Chennai, Coimbatore, Kochi, Thiruvananthapuram, Bangalore, Hyderabad, Kolkata, Mumbai, Ahmedabad, Pune, Nagpur and Indore.
All hospitals with a minimum of 100 beds, which have completed at least 2 years of being operational, and which have received 5 per cent or more of the total nominations from physicians were included in the survey.
All pathology labs and imaging centres, which have received 5 per cent or more of the total nominations from physicians, radiologists and pathologists were considered.
Until last year, rankings were based solely on a reputational survey conducted among health care experts. But this year's survey has taken factual data into account in the rankings. A primary survey was conducted among 917 experts—328 general physicians, 442 specialists and 147 pathologists/radiologists.
A questionnaire was given to the experts asking them to nominate and rate the top five multi-speciality hospitals in India and within their city. Specialists were asked to nominate and rate the top five hospitals for their specialisation. All experts in the top six metros nominated the top five pathology laboratories and imaging centres in their city.
Apart from this, 77 qualitative interviews that went beyond nominations and ratings were also done to get an in-depth understanding of the reasons for the rankings.
Factual information collection
As many as 222 multi-speciality hospitals were invited through email and telephonic calls to provide factual information about their hospital through a questionnaire. An advertisement was printed in THE WEEK inviting hospitals to volunteer information. Within the stipulated time, 63 hospitals responded, but two did not meet the eligibility criteria.
The following parameters were used for rankings: overall reputation of the hospital, competency of doctors, infrastructure, availability of multiple specialities, patient care, hospital environment and innovation in treatment.
For multi-speciality hospitals in India, ranking was based on a composite score derived by combining the perceptual and factual score of the hospital. For hospitals which could not respond to the survey with factual information, the composite score was derived by combining the perceptual score for the hospital with an interpolated appropriate factual score.
Final Score for a hospital for all-India ranking = perceptual score (400) + factual score (600)
Calculation of perceptual score
Perceptual score for a hospital was calculated on the basis of the number of nominations received, actual rank given and ratings given to the hospital on the seven parameters mentioned above.
Calculation of factual score
The components used to compute the factual score and their weights are given below:
Pedagogy (100): Defined by age of the hospital, accreditation and association with teaching institutes
Human resources (160): Defined using proportion of full-time doctors, doctors-to-bed ratio, number of nurses and so on
Infrastructure and other patient facilities (180): Defined using number of beds, operation theatres, and other patient services
Volume of work (160): Defined by the size of in-patient admissions, OPD and surgeries done
For multi-speciality hospitals within 16 cities, in Mumbai, Chennai, Bangalore, Hyderabad and Ahmedabad, at least 60 per cent of the top hospitals (as nominated by physicians) participated in the factual survey. For the remaining 11 cities, less than 60 per cent participated. So, while a factual plus perceptual ranking has been provided for Mumbai, Chennai, Bangalore, Hyderabad and Ahmedabad, a pure perceptual ranking has been done in the remaining 11 cities.
The top 10 hospitals for 10 specialities and pathology laboratories and imaging centres within top six metros were ranked using only perceptual data.
