Ensconcing a biostatistics clinic in tertiary care research institute of India: A descriptive study

Abstract

Context: Data collection and statistical analysis are integral components of research. The beauty of statistics lies in its ability to evaluate evidence in the face of uncertainty. However, lack of dedicated biostatistical consultation units, rote academic teaching and training lead to poor statistical analysis. Thus, we aim to explore and understand the challenges of establishing a Biostatistics Clinic (BC) in a tertiary care research institute. A secondary aim is to identify the stage of research at which participants approach biostatisticians.

Material and methods: The data for the current study came from a consultancy unit named as "Biostatistics Clinic" in the department of biostatistics from Post Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. The residents and students who approached the department of biostatistics for consultancy regarding study design, sample size, statistical analysis and other analytical work were the sampling units.

Results: A total of 208 residents and students made 404 visits to biostatistics clinic. The male and female visits were 118 (56.7%) and 90 (43.5%), respectively. Majority of visitors approached for data analysis (171; 75%) followed by study design and sample size calculation for protocol preparation (43; 18.9%). Leading reference to approach the biostatistics clinic was through a faculty (91; 43.8%) followed by self (54; 26%).

Conclusion: Despite the thrust and apparent advantages of contacting statistician at the beginning of the study, majority approached only at the data analysis stage. Therefore, repeated and improved efforts are required to spread the message of approaching statistician early.
