Risk Factors Analysis Of The Elderly Diabetic Patients With Infection

In our country the majority of diabetes are the old diabeticpatients,Elderly patients with diabetes are easy to merge withchronic complications, such as coronary heart disease,diabetic nephropathy, diabetes foot, neurological disease,cerebrovascular disease, retinopathy etc. Also they are easyto merge with acute complications,such as Hypoglycemia,ketoacidosis,lactic acidosis and they are extremely easyinfection.Diabetes and infection influence each other as well.Especially the elder, whose immune function is low, organsfunction decline, so that make the illness complex,hospitalization rate higher, the course longer,and morevulnerable to be infected,which leads to aggravatediabetes.Hyperglycemia can make infection difficult to becontrolled and easily form a vicious circle.Diabetes mellituswhich merged with infection is the most common lethal cause.Objective: Analysing the elderly diabetic infection characteristics,the sites of infection and its related risk factors.So thatimproving the elderly diabetes’ understanding of thenosocomial infection,so as to effectively control theincidence rate of elderly patients with infection.Methods:On July2011-November2012in our hospital,540cases ofelderly patients with diabetes were retrospectively analyzed,232cases who merged with infection were determined after thecollection and analysis of the data.without co-infectionpatients308cases of infection. There are263cases of male and277female patients in540patients whose age ranged in the60-87years old,their average age is70.41. Understanding thedatum which cover the patients’ history, duration of diabetes,age, gender, weight, calculation of body mass index (BMI), andblood testing glycated hemoglobin (HbA1c), fasting plasmaglucose (FPG), blood sugar after eating two hours(2HPG), fundus examination, peripheral nerve inspection, routine blood,urine and blood sedimentation,24hours urinary protein, bloodfat (total cholesterol, triglycerides, high-densitylipoprotein cholesterol, low density lipoprotein cholesterol,low density lipoprotein cholesterol), kidney (creatinine andurea nitrogen), antibiotics usage and the performance of theclinical infection. Analysing the results with SPSS19.0statistical software.Continuous variable uses x±s, the ratecomparison between the two groups uses x2test, and thecomparison of the mean uses t test, classification variablesuses%, the disease risk factors use Logistic regressionanalysis.Results:1-32years course of the disease in540patients, whichaverage is9.33years. Co-infection in patients with an averageduration of9.36±3.43years.The admission average fastingblood glucose is9.36±2.75mmol/l. The abnormal blood pressureaccounted for46.55%and the abnormal blood fat accounted for 62.5%.The most common infection are respiratory system infectionwhich has119cases (37.07%), followed by84cases of urinarysystem(26.17%), also there is53cases of skin softtissue(19.94%),34cases of the digestive system (10.59%)，and20cases of other infections (6.23%).The logisticregression model arrives at the infection risk factors of bymaking many factor analysis of elderly diabetes mellitus (95%CI>1, P <0.05);Respiratory system infection is related tofasting plasma glucose(P <0.05); Urinary tract infection isrelated to gender (P <0.05); Skin soft tissue infection isrelated to blood fat (P <0.05); The digestive system infectionare related to blood pressure (P <0.05).Conclusions:The main infection parts of elderly patients with diabetesis the respiratory system, urinary system, digestive system,skin and soft tissue; It is the characteristics of infectionfor elderly diabetes who combined with a few site of infection; Blood glucose, blood pressure, blood fat and gender are the riskfactors of infection for the elder hospitalized patients.
