Comparative Analysis Of Risk Factors For Pressure Ulcers Outside The Hospital From Different Sources

Objective:Understand the risk factor of pressure sores outside the hospital, comparie pressure sores outside the hospital of different sources, explore the difference of risk factorst.To effectively prevent pressure sores outside the hospital, provides the theory basis.And we can also take effective measures to reduce occurrence rate of pressure sores outside the hospital.Method:With the method of retrospective survey study, review on January1,2012to August1,2013the database data from hospital safety management system in a level of first-class hospital. With the aid of hospital information management system we can collect patients various laboratory tests results. We divide pressure sore patients into two groups according to the sources of pressure sores.They are the family and the non-family groups.The family groups mainly are patients from the family to hospital, The non-family groups are patients mainly from the nursing home admission to hospital.With Excel2007Chinese version, input all data and set up the database.Examine the effectiveness of the form. Statistical analysis was operated by SPSS17.0software.Significance level at P<0.05show statistically significant of difference. The measurement data was expressed by (x±s) and analyzed by t test、χ2test and Logistic regression analysis.Results:1. This study collected155cases of patients with pressure ulcers, including113(73%) family groups and42(27%) non-family groups. The family groups are far more than the non-family groups.There are89(57%) male patients and66(43%) female patients;19(9%) patients with I period,65(32%) patients with Ⅱ period,70(34%) patients with Ⅲ period,38(19%) patients with IV period,10(5%) patients with suspected deep tissue injury period,2(1%) patients with non-distinguish period;98(33%) cases of sacral tail,44(15%) cases of hip,27(9%) cases of haunch,41(14%) cases of heel,9(3%) cases of the knee,77(26%) cases of the other parts;32(21%) cases cured,109(70%) cases improved,14(9%) cases markedly no improved, no worse patients.2.Through the analysis of the general data, two groups of patients data between age and distribution department have significant difference (P<0.05). Of pressure ulcer stage, the developed area, the effects of pressure ulcer treatment, pressure sores Braden score there was no significant difference.3.Through the analysis of various factors, the top five risk factors are limited positions (86.5%), movement disorders (78.1%), skin damage (78.1%), malnutrition (69.0%) and abnormal blood pressure (63.9%). Through comparing the family and the non-family group in risk factors for pressure ulcers, four factors were screened with statistical significance (P<0.05), including viscera function failure、mechanical ventilation the nutritional status and temperature.4. Let the location of pressure ulcers as the dependent variable, the statistically significant factors through comparing the family and the non-family group as independent variables, through Logistic multivariate regression analysis, select two factors, including age (OR=1.0), temperature (OR=0.3).Conclusion:1.The proportion of family groups in all pressure sores outside the hospital are much higher than the non-family groups. The ratio of male patients is higher than female patients. The Ⅱ and Ⅲ period patients have a large proportion in all pressure sores outside the hospital. There are more pressure sores in the sacral tail.The most pressure sores outside the hospital after treatment can be improved.2.The average age of the family groups is higher than the non-family groups. The family groups patient mostly distributed in the general ward, the non-family groups patient mostly distributed in intensive care units.3. The occurrence of pressure ulcers outside the hospital have multiple risk factors, including limited position, movement disorders, skin damage, malnutrition, and abnormal blood pressure. The four factors of viscera function failure, mechanical ventilation, the nutritional status and temperature have the role of different sizes in the family groups patients and the non-family groups patients,4. Age and body temperature in the occurrence of pressure sores in the family groups and the non-family groups are the two main factors. Age in the family groups played a very important role in the occurrence of pressure sores outside the hospital, temperature in the non-family groups played a large role in the occurrence of pressure sores outside the hospital.
