ABSTRACT
Objective:To improve the evaluation method of hospital beds efficiency based on diagnosis-related groups (DRG), and to provide a basis for hospitals to allocate beds reasonably and improve bed efficiency.Methods:Taking a tertiary hospital in Beijing as the research object, the types of beds were evaluated by the beds utilization matrix with the time consumption index as the X-axis and the bed utilization rate as the Y-axis. The types of beds in the department were divided into efficiency type, pressure type, turnover type, and idle type. The efficiency of medical services and the level of diagnosis and treatment were evaluated by the weight of DRG per bed. The calculation method of theoretical number of beds was improved by incorporating hospital case mix index as a risk adjustment factor into the formula to evaluate the status of beds allocation. Combining the bed type, DRG weight per bed, and bed allocation status, the improvement emphasis and management strategy of bed utilization could be comprehensively analyzed.Results:Among the 24 departments in the hospital, there were 5, 9, 1 and 9 departments being efficiency type, pressure type, turnover type and idle type, respectively. The weight per bed of 11 departments was higher than the average level of the hospital. There were 16, 5, and 3 departments with appropriate, fewer, and excessive beds, respectively.Conclusions:The comprehensive analysis of beds utilization type, allocation status and weight of each bed based on DRG is an effective method to evaluate the efficiency of hospital beds, and can provide decision-making basis for hospital bed resource allocation, hospital operation focus adjustment, and subject development planning.
ABSTRACT
Objective@#To study the effect of postoperative application of tranexamic acid on recovery and prognosis of unilateral total hip arthroplasty.@*Methods@#One hundred and twenty patients who received unilateral total hip arthroplasty in 541st General Hospital of Dongzhen Town from August 2016 to August 2018 were divided into observation group and control group by random number table method, with 60 cases in each group. The control group received intravenous injection of tranexamic acid 10 min before skin incision after anesthesia; on the basis of the control group, the observation group was given tranexamic acid intravenously again 3 h after operation, and the control group was no longer given repeated injection of tranexamic acid. The hemorrhage, hemoglobin (Hb), hematocrit(HCT), hip joint Harris score and complications were compared between the two groups.@*Results@#There was no significant difference in intraoperative blood loss and transfusion between the two groups (P>0.05); the drainage volume, total blood loss, dominant blood loss and recessive blood loss in the observation group were lower than those in the control group [(227.43 ± 20.14) ml vs. (280.91 ± 23.56) ml, (601.01 ± 42.84) ml vs. (667.04 ± 49.21) ml, (281.93 ± 18.50) ml vs. (322.06 ± 21.23) ml, (330.94 ± 21.73) ml vs. (370.03 ± 25.90) ml] (P<0.05). After operation 3 d, the levels of Hb and HCT in observation group were higher than those in control group [(117.07 ± 9.60) g/L vs. (102.19 ± 8.31) g/L, (35.05 ± 2.91)% vs. (32.01 ± 2.77)%] (P<0.05). After operation 2 weeks and 1 month after operation, the hip joint Harris score in observation group was higher than that in control group [(52.03 ± 4.02) scores vs. (48.37 ± 5.05) scores, (67.86 ± 5.29) scores vs. (61.23±5.10) scores] (P<0.05). There was no significant difference in the occurrence of intermuscular venous thrombosis, local hematoma and incision exudation between the two groups(P>0.05).@*Conclusions@#On the basis of preoperative application of tranexamic acid, combined postoperative application of tranexamic acid can significantly reduce the blood loss after unilateral total hip arthroplasty, and help the early recovery of joint function, without increasing complications and with high safety.
ABSTRACT
study the effect of postoperative application of tranexamic acid on recovery and prognosis of unilateral total hip arthroplasty. Methods One hundred and twenty patients who received unilateral total hip arthroplasty in 541st General Hospital of Dongzhen Town from August 2016 to August 2018 were divided into observation group and control group by random number table method, with 60 cases in each group. The control group received intravenous injection of tranexamic acid 10 min before skin incision after anesthesia; on the basis of the control group, the observation group was given tranexamic acid intravenously again 3 h after operation, and the control group was no longer given repeated injection of tranexamic acid. The hemorrhage, hemoglobin (Hb), hematocrit(HCT), hip joint Harris score and complications were compared between the two groups. Results There was no significant difference in intraoperative blood loss and transfusion between the two groups (P＞0.05); the drainage volume, total blood loss, dominant blood loss and recessive blood loss in the observation group were lower than those in the control group [(227.43 ± 20.14) ml vs. (280.91 ± 23.56) ml, (601.01 ± 42.84) ml vs. (667.04 ± 49.21) ml, (281.93 ± 18.50) ml vs. (322.06 ± 21.23) ml, (330.94 ± 21.73) ml vs. (370.03 ± 25.90) ml] (P＜0.05).
