Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Background: The best insulin regimen to treat hyperglycemia in hospitalized patients on nutritional support (NS) is unclear. Methods: We searched electronic databases to identify cohort studies or randomized clinical trials in order to evaluate the efficacy of different insulin regimens used to treat hyperglycemia in hospitalized patients on NS on diverse outcomes: mean blood glucose (MBG), hypoglycemia, length of stay in hospital, and mortality. Results: Seventeen studies from a total of 5,030 were included. Enteral Group included 8 studies; 1,203 patients using rapid, glargine, NPH, or Premix insulin; MBG 108-225 mg/dL; hypoglycemia 0-13%. In indirect meta-analyses, NPH insulin ranked best for glucose control (MD 95% CI -2.50 mg/dL [2.65 to -2.35]). Parenteral Group included 4 studies; 228 patients using regular and glargine or NPH insulin; MBG 137-202 mg/dL; hypoglycemia 0-40%. In meta-analyses comparing regular insulin added to parenteral nutrition bag with glargine, MBG (MD 95% CI -3.78 mg/dL [-11.93 to 4.37]; I2 = 0%) or hypoglycemia frequency (RR 95% CI 1.37 [0.43-4.32]; I2 = 70.7%) did not differ. The description related to hospital length of stay and mortality was inconsistent between groups. Conclusions: The best insulin regimen to treat hyperglycemia in hospitalized patients on NS has not been established; best results using insulin regimens with NPH in enteral nutrition do not seem to be clinically relevant.
