Back ground: Diabetes is a serious, chronic disease that occurs either when the pancreas does not produce enough insulin (a hormone that regulates blood sugar, or glucose), or when the body cannot effectively use the insulin it produces.

Methodology: The purpose of this study was to identify factors that affect the survival time of in-patient diabetics in BFHRH. Among 3730 inpatient diabetics who were followed in Bahirdar Felegehiwot Referral Hospital during  September 2011 to August 30 2017, 480 samples (47 children and 433 adults) were selected from 366 children and 3364 adult inpatient diabetic populations respectively. The samples from the two groups of population were selected using proportional sample size allocation formula. After selecting proportional samples from the two groups of populations, systematic random sampling method was employed to select patients that were participant in the study. To determine factors that affect the survival time of in-patient diabetics, compare the survival time as well as examine the association between the survival time with different demographic and clinical variables, the Kaplan Meier estimation method and the parametric regression model were applied.

Result: The result from Kaplan-Meier estimation revealed that the survival time of IDM patients is significantly related with age, diabetic disease complication, place of residence, family history of DM, systolic & diastolic blood pressure, HIV/or TB co-infection, cholesterol level and type of diabetic disease diagnosed. The Log rank result also indicates that the survival time of diabetic patients is not statistically different in experiencing the death event among group classified by sex. The result of the Weibull regression model indicated that complication of DM, family history of DM, systolic blood pressure, HIV / or TB Co-infection and cholesterol level significantly contributed to shorter survival time of DM patients.

Conclusion: the findings of this study shows that diabetic disease complication, family history of DM, systolic blood pressure, HIV/or TB co-infections and cholesterol level are major factors that affect the survival time of in-patient diabetics. The researcher recommended that the people should be aware on the burden of those risk factors and well informed about the disease.

Key Words: In-patient diabetics, survival time, Weibull survival regression model.
