ObjectiveTo understand the current national status of the rating of published orthopedic guidelines and consensus in China, to help users select the appropriate use of these clinical guidelines, to guide clinical practice, and to promote the targeted improvement of the quality of Chinese orthopedic guidelines and consensus. MethodsChinese biomedical databases, including CNKI, WanFang Data, and SinoMed were searched electronically from January 2016 to October 2023, and relevant Chinese orthopedic clinical practice guidelines and consensus documents were collected. Two evaluators independently screened the retrieved literature and extracted data. The scientificity, transparency, and applicability rankings (STAR) tool was used to comprehensively rate Chinese orthopedic guidelines and consensus documents published in medical journals since 2016. Any dispute between the two evaluators was resolved by consulting a third evaluator. Kappa values were used to evaluate the consistency of the results between the two evaluators. ResultsA total of 191 orthopedic-related guidelines and consensus documents were obtained, including 74 guidelines and 117 consensus documents. The average score of the guidelines included in the evaluation was 34.4 points, while the average score of consensus documents included in the evaluation was 21.7 points. Guidelines scored higher than consensus documents in areas such as registration, planning, workgroups, clinical issues, evidence, consensus methods, recommendations, accessibility, and other fields. The Kappa value test result was 0.684. ConclusionThere has been a progressive increase in methodological scores of Chinese orthopedic clinical practice guidelines and consensus documents published in recent years, but the overall quality is not high. Future guidelines development needs to improve methodology further, especially in terms of transparent funding, formation of recommendations, guidelines release, and dissemination.
ObjectiveTo analyze the risk factors of acute wound infection in orthopedic patients. MethodsA retrospective analysis was made on the clinical data of 576 orthopedic patients in accordance with the inclusion criteria between July and October 2012. There were 345 males and 231 females, aged 18-95 years (mean, 44 years). Single factor analysis was used for related factors, and logistic regression analysis of multi-factors for risk factors of acute wound infection. ResultsWound infection occurred in 73 of 576 patients (12.7%). Single factor analysis showed that the influence factors were gender, education, smoking history, nutritional status (hemoglobin, red blood cell count, serum albumin, and total serum protein), blood glucose level, shock history, wound situation (characteristics, multiple injuries, and cleaning), type of injuries, the time of trauma handling, antibiotic use, whether to stay in ICU, wound pain score, drug analgesia, patient controlled analgesia, and dressings and cleaning solution choice. The logistic regression analysis showed that the gender, time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics were the risk factors of acute wound infection (P<0.05). ConclusionTo achieve the best results in clinical prevention of infection, these risk factors (gender, the time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics) should be considered well.
ObjectiveTo investigate the effectiveness of the Ilizarov technique for the treatment of traumatic talipes equinovarus so as to provide the evidence for the clinical practice. MethodsBetween February 2011 and April 2012,42 patients with traumatic talipes equinovarus received treatment by Ilizarov technique,including 29 males and 13 females aged 17-55 years (mean,34.3 years).The left side was involved in 24 cases,and the right side in 18 cases.The disease duration was 6 months to 6 years (mean,2.7 years).According to the principles of Ilizarov,a ring external fixator was applied on the affected foot and lower leg.The threaded rods and screw nuts were revolved according to the tolerance of patients at 3-7 days after fixation.At first,forefoot varus or foot inversion was corrected,and then drooping feet deformity was corrected.The patients were encouraged to begin weight-bearing walking after correction.X-ray films were taken regularly to observe the ankle joint and avoid its dislocation.The external fixator was maintained in neutral position for 8-12 weeks after achieving satisfactory correction.An walking ankle-foot orthosis and a sleeping ankle-foot orthosis were used for more than 16 weeks after removal of the fixator.The outcome was assessed with American Orthopaedic Foot and Ankle Society (AOFAS) comprehensive scoring system and visual analogue scale (VAS) pain score. ResultsForty-two patients were followed up 14.3 months on average (range,10-24 months).All the patients achieved 0° dorsiflexion at 4-13 weeks (mean,6.8 weeks) after treatment with Ilizarov apparatus.The fixator was maintained for 10.7 weeks on average (range,10-16 weeks) after correction.No dislocation of the ankle joint and no damage to nerves and blood vessels occurred.The deformity of plantar flexion (10°) was found in 3 patients.At last follow-up,the patients could walk normally.AOFAS score was significantly increased to 93.4±8.0 from 52.7±10.1 at preoperation (t=-7.035,P=0.008);according to AOFAS scoring system,24 cases were grades as excellent,14 as good,2 as moderate,and 2 as poor,and the excellent and good rate was 90.5%.The VAS score of the foot significantly decreased to 3.51±1.44 from 7.55±1.39 at preoperation (t=-0.564,P=0.025). ConclusionIlizarov technique combined with non-fusion has satisfactory effectiveness in correction of traumatic talipes equinovarus.It is a safe,effective,and minimally invasive method.
ObjectiveTo analyze the clinical characteristics, risk factors, and drug resistance of pathogenic bacteria in patients with blood stream infections (BSI) after orthopedic surgery, so as to provide reference and basis for clinical diagnosis and treatment.MethodsA retrospective analysis was made on the clinical data of 6 348 orthopedic patients admitted for surgery between January 2017 and December 2019. There were 3 598 males and 2 750 females. Their age ranged from 18 to 98 years, with an average of 66 years. The data of patients were collected, and the risk factors of BSI were analyzed by univariate analysis and logistic regression analysis. The distribution of BSI pathogenic bacteria, the results of drug sensitivity test, the incidence of BSI in patients after orthopedic surgery in different years, and the common sites of BSI secondary infection were summarized.ResultsBSI occurred in 106 (1.67%) of 6 348 patients after orthopedic surgery. There were 71 cases (66.98%) of secondary infection. The mortality of postoperative BSI patients was 1.89%, and the difference was significant when compared with that of non-postoperative BSI patients (0.24%) (χ2=5.313, P=0.021). The incidences of BSI in 2017, 2018, and 2019 were 1.18%, 1.53%, and 2.17%, respectively, showing an increasing trend year by year (trend χ2=6.610, P=0.037). Statistical analysis showed that the independent risk factors for BSI after orthopedic surgery (P<0.05) included the trauma, length of hospital stay≥14 days, emergency surgery, postoperative leukocyte counting<4×109/L, level of hemoglobin≤90 g/L, albumin≤30 g/L, the time of indwelling ureter>24 hours, use of deep vein catheter insertion, and merging other site infection. Blood culture showed 56 strains (52.83%) of Gram-positive bacteria, 47 strains (44.34%) of Gram-negative bacteria, and 3 strains (2.83%) of fungi. The top three pathogenic bacteria were coagulase negative Staphylococci (CNS; 36 strains, 33.96%), Escherichia coli (16 strains, 15.09%), and Staphylococcus aureus (15 strains, 14.15%). The detection rates of extended-spectum β-lactamases producing strains of Escherichia coli and Klebsiella pneumoniae were 56.25% (9/16) and 44.44% (4/9), respectively. The detection rates of methicillin-resistant strains in Staphylococcus aureus and CNS were 46.67% (7/15) and 72.22% (26/36), respectively.ConclusionPostoperative BSI in orthopedic patients is caused by multiple factors. Preventive measures should be taken according to related risk factors and perioperative risk assessment should be strengthened. Staphylococcus and Escherichia coli are the most common pathogenic bacteria in BSI after orthopedic surgery. The infection rate and drug-resistant bacteria are increasing year by year. Therefore, drug resistance monitoring should be strengthened.
Objectives To explore the application effect of orthopedic psychological sleep management mode based on enhanced recovery after surgery (ERAS) in orthopedic patients. Methods A non-synchronous clinical controlled study was conducted. The intervention group enrolled 118 orthopedic patients who admitted to our hospital between April and June 2017, and the control group enrolled 111 orthopedic patients who admitted to our hospital between January and March 2017. The control group used routine nursing measures during hospitalization, while the intervention group implemented an ERAS-based orthopedic psychological sleep management mode based on routine nursing measures, which included carrying out a new mode of multidisciplinary collaborative management, implementing the normative path of orthopedic psychological sleep management, and implementing the comprehensive psychological sleep management. The mood, sleep quality and satisfaction of the two groups within 24 hours after admission and before discharge were compared. Results Before the intervention, there was no statistically significant difference in general data, mood or sleep quality between the two groups (P>0.05). After the intervention, the median score (the lower and upper quartiles) of the Huaxi Emotional Index of the intervention group was 1 (0, 5), while the score of the control group was 2 (0, 6); the median score (the lower and upper quartiles) of the Pittsburgh Sleep Quality Index was 4 (3, 7) in the intervention group and 6 (4, 9) in the control group; the satisfaction score in the intervention group was better than that in the control group (96.47±2.72vs. 95.52±2.79); the differences between the two groups were statistically significant (P<0.05). Conclusions The ERAS-based orthopedic psychological sleep management mode is beneficial to improve the patients’ emotional disorder, sleep quality and satisfaction. It facilitates the patients’ accelerated recovery.
