Statistical methods / analysis
Primary analysis by two-tailed bivariate correlation of HbA1c with length of stay using a Pearsons product-moment correlation coefficient as both variables are interval type. Using an Alpha error of 0.05, a Beta error of 0.95, and a correlation coefficient of 0.5, sample size was calculated at 38 participants in each of the total knee and total hip arms of the study.

Summary
Brief summary
The main focus of this project is to identify whether a correlation exists between HbA1c levels and the hospital length of stay (LOS) following total hip or total knee replacements at Mackay Base Hospital. Elevated HbA1c blood levels are an indication of poor glucose control over the preceding months and are used as a surrogate marker to predict micro and macro vascular complications in diabetics. We aim to measure HbA1c in all patients within our cohort, and look for a statistically significant correlation with LOS. The practical implication if a positive correlation is established is that improvement of HbA1c with lifestyle and medication prior to major elective surgery such as lower limb total arthroplasty, may significantly lower the cost burden upon the health system by reducing LOS. Research is limited and conflicting in this area, and further elucidation of a correlation would advance understanding and guide further research.
