  • Study on the economic burden of healthcare-associated infections in Sichuan Province

    ObjectiveTo measure and evaluate the economic burden of hospital infection in Sichuan, and provide a basis for targeted economic evaluation of healthcare-associated infection (HAI).MethodsIn hospitals participating in the 2016 Sichuan provincial prevalence survey of HAI, matched cases were used to extract cases and controls, and then a multi-center nested case-control study was conducted.ResultsA total of 225 pairs/450 patients were selected in 51 hospitals, and 175 pairs/350 patients were successfully matched. The median of the difference of hospitalization costs between matched-pairs were RMB 3 362.0, and the difference was statistically significant (Z=3.275, P<0.001).ConclusionsThe hospitalization costs caused by HAI should be given special attention in the current medical insurance reform. Efforts need to be taken to reduce the hospitalization costs caused by HAI.

  • Short-term effectiveness of orthopedic robot-assisted resection for osteoid osteoma

    Objective To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery. Methods A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference (P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed. Results All patients completed the surgery successfully, with no significant difference in surgical time between the two groups (P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences (P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant (P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery (P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups (P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time (P<0.05), but there was no significant difference between the two groups after surgery (P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups (P>0.05). Conclusion Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.

  • Analysis of influencing factors of postoperative delirium after endovascular aortic repair: A case-control study

    Objective To analyze the influencing factors of delirium after endovascular aortic repair (EAR) and to provide evidence for clinical nursing and prevention of this disease. Methods Patients who underwent EAR at Fuwai Hospital, Chinese Academy of Medical Sciences from 2018 to 2019 were selected and assessed for postoperative delirium by Nursing Delirium Screening Scale (Nu-DESC). Nu-DESC score≥3 was divided into a delirium group (a case group), the non-delirium patients with the same operation and adjacent operation sequence were selected, and the ratio of 1∶4 was included in a non-delirium group (a control group). The clinical data between the two groups were compared by univariate analysis, and the significant risk factors in the univariate analysis were analyzed by multivariate logistic regression to determine the influencing factors of postoperative delirium. And stratified analysis was conducted based on thoracic endovascular aortic repair (TEVAR) and abdominal aortic repair (EVAR). Results A total of 213 patients were included in this study, including 46 patients in the case group and 167 patients in the control group. The mean age was 60.3±12.0 years, and 183 (85.9%) patients were male. Univariate analysis showed that emergency admission, preoperative neutrophil percentage, operation duration, intubation duration, and ICU duration may be associated with postoperative delirium. Multivariate analysis showed that the longer the duration of surgery and intubation, the more likely the patient was to develop delirium. In stratified analyses, the results were consistent with the general population in the TEVAR group, while no significant difference was found in the EVAR group. Conclusion The longer the operation time and tracheal intubation time are, the more prone to delirium patients undergoing TEVAR surgery are. While EVAR patients have no significant difference.

  • Risk factors for full-term prelabor rupture of membranes: a prospective nested case-control study

    Objective To investigate the incidence of full-term prelabor rupture of membranes (FPROM) and risk factors for FPROM. Methods A prospective nested case-control study was performed on pregnant women in early pregnancy and their spouses, who underwent prenatal examination for the first time in Zhuhai Center for Maternal and Child Health Care from May 2021 to December 2022. Pregnant women with a clear diagnosis of FPROM were included in the case group, and pregnant women without FPROM were randomly selected at a 1∶3 ratio for inclusion in the control group. A questionnaire survey was performed to collect exposure information possibly related to FPROM. The hospital's medical record system was used for information verification and to record the pregnancy outcomes. A multivariate logistic regression analysis was used to investigate the risk factors for FPROM. Results The incidence of FPROM in this study was 24.27%. The multivariate logistic regression analysis showed that obesity pregnant women, smoking, drinking, unbalanced diet, high-intensity physical activity during pregnancy, eating areca nut before pregnancy, using glucocorticoids during pregnancy, older at the time of first pregnancy, a history of adverse pregnancy outcomes, a history of pregnancy complications, a history of diabetes, a history of scar uterus, no folate supplementation during pregnancy, repeated intrauterine operations, polyembryony, polyhydramnios, transverse fetus and fetal cephalopelvic disproportion as the way of conception were risk factors for FPROM (P<0.05). Additionally, the pregnant women whose spouses were obese or smoked or drinking had an increased risk of FPROM (P<0.05). Lower gravidity and lower parity were protective factors against FPROM (P<0.05). Conclusion There are many risk factors for FPROM. Special attention should be given to the life behaviors of pregnant women during pregnancy, and health education should be strengthened for pregnant women and their spouses to help them develop good living habits and reduce the incidence of FPROM.
