ObjectiveTo explore the effect of continuous improvement of quality control system on the emergency treatment efficiency for patients with acute ST segment elevation myocardial infarction (STEMI) after the establishment of Chest Pain Center. MethodsWe retrospectively analyzed the differences of theory examination scores acquired by the Chest Pain Center staff one month before and after they got the system training. Moreover, we designated the STEMI patients treated between May and August 2015 after the establishment of Chest Pain Center but before optimization of process to group A (n=70), and patients treated from September to December 2015 after optimization of process to group B (n=55). Then we analyzed the differences between these two groups in terms of the time from patients' arriving to registration, the time from arriving to first order, the length of stay in Emergency Department, and even the time from door to balloon (D2B). ResultsThe scores acquired by Chest Pain Center staff before and after system training were 69.89±6.34 and 87.09±4.39 respectively, with a significant difference (P＜0.05). All the time indicators of both group A and group B were shown as median and quartile. The time from patients' arriving to registration of group A and group B was 6.0 (0.0, 11.0) minutes and 1.0 (0.0, 3.0) minutes (P＜0.05); the time from arriving to first order was 12.8 (9.0, 18.0) minutes and 5.0 (3.0, 9.0) minutes (P＜0.05); the length of stay in Emergency Department was 54.0 (44.0,77.0) minutes and 33.0 (20.0, 61.0) minutes (P＜0.05); and the time of D2B was 107.5 (89.0, 130.0) minutes and 79.0 (63.0, 108.0) minutes (P＜0.05). ConclusionAfter taking measures such as drawing lessons from the past, training staff and optimizing process continuously, we have significantly shortened the acute STEMI patients' length of stay in the Emergency Department, which has saved more time for the following rescue of STEMI patients.
ObjectiveTo evaluate the role of triclosan-coated polyglactin 910 suture in reducing wound infections of emergency gastrointestinal surgeries. MethodsThis was a prospective, randomized, controlled, single center study. From May 2009 to August 2010, 412 patients underwent emergency gastrointestinal operations in our department, 198 of them were chose randomly as experimental group using triclosancoated polyglactin 910 suture for abdominal wall closure， 214 using traditional braiding suture were taken as control. The risk factors for wound healing were analyzed, and wound infection rate was compared between two groups. ResultsThere were no significant differences of gender, age, body mass index, combined diabetes, use of immunosuppressant, and glucocorticoid steroid, type of incision, intraoperative bleeding volume, and operation time between two groups (Pgt;0.05). Wound infection rate of experimental group 〔3.0% (6/198）〕 was significantly lower than that of control group 〔11.7% (25/214), Plt;0.001〕. Especially in subgroup of type Ⅲ incision and operative time more than 120 min, wound infection rate was significantly different between experimental group and control group 〔3.5%(5/141) versus 14.3%(22/154); 3.3%(2/60) versus 21.2%(11/52) respectively, Plt;0.001〕. ConclusionTriclosancoated polyglactin 910 suture can reduce wound infection rate of gastrointestinal emergency operations, especially with type Ⅲ incision and operation time ≥120 min.
Objective To investigate the clinical features, etiology and treatment strategies of patients with delirium in emergency intensive care unit ( EICU) . Methods Patients with delirium during hospitalization between January 2010 and January 2012 were recruited from respiratory group of EICU of Beijing Anzhen Hospital. Over the same period, same amount of patients without delirium were randomly collected as control. The clinical datawere retrospectively analyzed and compared. Results The incidence of delirium was 7.5% ( 42/563) . All delirium patients had more than three kinds of diseases including lung infections, hypertension, coronary heart disease, respiratory failure, heart failure, renal failure, hyponatremia, etc. 50% of delirium patients received mechanical ventilation ( invasive/noninvasive) . The mortality of both the delirium patients and the control patients was 11.9% ( 5 /42) . However, the patients with delirium exhibited longer hospital stay [ 14(11) d vs. 12(11) d, P gt;0. 05] and higher hospitalization cost [ 28, 389 ( 58,999) vs. 19, 373( 21, 457) , P lt;0.05] when compared with the control group. 52.4% ( 22/42) of delirium patients were associated with primary disease. 9. 5% ( 4/42) were associated with medication. 38. 1% (16/42) were associated with ICU environment and other factors. Conclusions Our data suggest that the causes of delirium in ICU are complex. Comprehensive treatment such as removal of the relevant aggravating factors, treating underlying diseases, enhancing patient communication, and providing counseling can shorten their hospital stay, reduce hospitalization costs, and promote rehabilitation.
ObjectiveTo probe into the writing quality and rational use of drugs for Emergency Department prescriptions in West China Hospital of Sichuan University. MethodsFrom January 2012 to December 2013, the prescriptions for emergencies were selected randomly. According to prescription management method and standard management of hospital prescription comment requirement, the quality of prescription was analyzed. ResultsFrom 2012 to 2013, the qualified prescription rate increased from 91.45% to 96.70%. The average number of drugs on each prescription was 1 or 2; the utilization rate of antibacterials was below 20.00%; the utilization rate of essential drugs increased from 60.68% to 66.15%; the utilization rate of generic drug name approached 100.00%. However, the utilization rate of injections increased from 82.92% to 85.67%. ConclusionBy prescription reviews, we have listed the problems, and intervened irrational prescription to improve the rate of qualified prescriptions. The high rate of injection utilization is a warning for us to take more effective, more specific and stricter intervention measures.
ObjectiveTo analyze the effect of noninvasive positive pressure ventilation (NPPV) on the treatment of severe acute pancreatitis (SAP) combined with lung injury [acute lung injury (ALI)/acute respiratory distress syndrome (ARDS)] in emergency treatment. MethodsFifty-six patients with SAP combined with ALI/ARDS treated between January 2013 and March 2015 were included in our study. Twenty-eight patients who underwent NPPV were designated as the treatment group, while the other 28 patients who did not undergo NPPV were regarded as the control group. Then, we observed patients' blood gas indexes before and three days after treatment. The hospital stay and mortality rate of the two groups were also compared. ResultsBefore treatment, there were no significant differences between the two groups in terms of pH value and arterial partial pressure of oxygen (PaO2) (P>0.05). Three days after treatment, blood pH value of the treatment group and the control group was 7.41±0.07 and 7.34±0.04, respectively, with a significant difference (P＜0.05); the PaO2 value was respectively (60.60±5.11) and (48.40±3.57) mm Hg (1 mm Hg=0.133 kPa), also with a significant difference (P＜0.05). The hospital stay of the treatment group and the control group was (18.22±3.07) and (23.47±3.55) days with a significant difference (P＜0.05); and the six-month mortality was 17% and 32% in the two groups without any significant difference (P>0.05). ConclusionIt is effective to treat patients with severe acute pancreatitis combined with acute lung injury in emergency by noninvasive positive pressure ventilation.
ObjectiveTo investigate the effect of pediatric medical transport network on transport and treatment for children in Sichuan province. MethodA total of 4647 pediatric patients transported to West China Second University Hospital were recruited from January 2011 and December 2013 in our study, among whom 1 948 were admitted before the establishment of the transport network (January 2011 to August 2012) and 2 699 were admitted after the establishment of the transport network (September 2012 to December 2013). Transport modes, patient disposition and fatality were analyzed to evaluate the role of transport network in the transport and treatment for pediatric patients. ResultsThe transported patients increased significantly after the establishment of transport network (an average of 97 cases increased to 169 cases per month). After transport network was established, valid communication and telephone contact also increased significantly (the proportion increased from 20.64% to 45.28%, P<0.001). There were significant differences in the composition of patients' destination after the establishment of the transport network (P<0.001). After the establishment of transport network, the patients' hospitalized rate and admission rate increased dramatically (from 17.86% to 37.53%, 12.11% to 41.13%, respectively). The fatality decreased from 6.83% to 3.04% (P<0.001). ConclusionsRegional pediatric transport network will contribute to the treatment of pediatric patients within the region, and decrease fatality.
