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 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.
Objective To investigate the inpatient’s disease and cost constitution of the Third People’s Hospital of Chengdu in 2009, so as to provide baseline data for further research. Methods The case records of inpatients in the Third People’s Hospital of Chengdu in 2009 were collected, and based on the first diagnose, the diseases were classified according to the International Classification of Diseases (ICD-10). The data including general information of the inpatients, discharge diagnosis and hospitalization expense etc. were rearranged and analyzed using Excel software. Results a) The total number of inpatients was 1 220, and male was more than female. The disease spectrum included 12 categories. b) A total of 1 093 inpatients suffered from the top 3 systematic diseases as follows: trauma and toxicosis, musculoskeletal system and connective tissue disorders, and the factors affecting health and resulting from contact with health care institutions. Except the musculoskeletal system and connective tissue disorders, the other 2 systematic diseases were mostly seen in male rather than in female. c) According to ICD-10, the top 9 diseases of trauma and toxicosis were injuries to the wrist and hand, injuries to the hip and thigh, injuries to the knee and lower leg, injuries to the shoulder and upper arm, injuries to the lower back, lumbar spine and pelvis, injuries to the elbow and forearm, injuries to the thorax, injuries to the neck and injuries to the ankle and foot; the top 4 diseases in musculoskeletal system and connective tissue disorders were dorsopathies, soft tissue disorders, arthrosis, and osteopathies and chondropathies; among the factors affecting health and resulting from contact with health care institutions, removal of fracture fixation device. d) According to ICD-10 (list of three-digit catalogue and four-digit sub-catalogue), the top 5 single diseases in trauma and toxicosis were muscle and tendon injuries of the wrist and hand, intertrochanteric frature, fracture of the femoral neck, fracture of the tibia and fibula, and fracture of the lumbar spine; the top 5 single diseases in musculoskeletal system and connective tissue disorders were lumbar disc herniation, spondylosis, arthrosis of the knee, osteoporosis with pathological fracture, and osteonecrosis. e) The average hospital stay were 23.55 days, and the average cost per capita were 13 073.73 yuan which were constituted by material cost, drug cost including western and Chinese medicines, treatment expenses including blood transfusion fee, operation expenses including anesthetic fee, examination expenses including radiation fee and laboratory fee, bed fee and others. The inpatient costs were mainly at patient’s own expense, nearly a half of those expenses were paid by social security, and public medical care only accounted for less than 3% of the total payment. Conclusion In 2009: a) The male inpatients were mainly the young and middle-aged, and the female were the elderly. The main 3 systematic diseases were trauma and toxicosis, musculoskeletal system and connective tissue disorders, and the factors affecting health and resulting from contact with health care institutions. Except the musculoskeletal system and connective tissue disorders, the other 2 systematic diseases were mostly seen in male rather than in female. b) The top 3 single diseases were lumbar disc herniation, muscle and tendon injuries of the wrist and hand, and intertrochanteric fracture. Except lumbar disc herniation, the other 2 single diseases were mostly seen in male rather than in female. c) The average hospital stay was 23.55 days. The overall costs were mainly constituted by material and drug cost (59.25%), with rationality worthy of attention. d) Inpatient costs were mainly at patient’s own expense or paid by social security, and the proportion of public medical care was low in the payment.
ObjectiveTo summarize the research and application progress of magnesium and magnesium alloys implants in the orthopedics. MethodsThe domestic and foreign related literature about the research progress and application of magnesium and magnesium alloys implants in the orthopedics was reviewed. ResultsCurrently approved and commonly used metallic implants in orthopedics include stainless steels, titanium alloys, and chromium alloys having many disadvantages of poor biocompatibility, mismatch with the biomechanical properties of the bone tissue, and need of second surgical procedure to remove. Compared with traditional implants, magnesium and magnesium alloys have biomechanical properties closer to natural bone tissue, and in vivo degradation, which have the potential to serve as new biocompatible and degradable implants. Although magnesium and magnesium alloy materials have their own advantages, but the degradation rate is still too fast and so on. At present, the research and development of medical magnesium and magnesium alloy materials are to improve their corrosion resistance and control the rate of degradation. ConclusionMagnesium and magnesium alloys have great potential as a implant material in the orthopedics, through further systematic and in-depth study, it is expected to become a new generation of degradation biological implant materials.
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.
Objective To investigate the orthopaedic inpatients’ disease and cost constitution of the Third People’s Hospital of Chengdu during 2008-2010, so as to provide detailed baseline data for further research on the factorial analysis of disease burden and effective intervention. Methods The medical records of inpatients in orthopaedic department of the hospital during 2008-2010 were collected, and the diseases based on the first diagnosis on discharge records were classified according to the International Classification of Diseases (ICD-10). Results During 2008 to 2010, the total number of inpatients increased year by year. Most of the male inpatients were the young and middle-aged, while the female were the old. The rank order of top 5 systematic diseases didn’t change, while there were 6 single diseases kept ranking as top 10 in those 3 years. The average cost per capita averagely grew by 8.97%. The top 3 constitution of hospitalization cost remained the same, which were material cost, drug cost, and treatment cost; while the top 3 payment modes of hospitalization cost were patient’s own expense, social security, and public expense. Among those payment modes, social security rose obviously, and patient’s own expense reduced generally. Conclusion a) The total number of inpatients increases yearly during 2008-2010, and the gender and age distribution of inpatients are tending towards stability. b) The spectrum of disease and single diseases classified according to the one-level code of ICD-10 are relatively stable in those 3 years; of which the top ranked disease is lumbar disc herniation, and the disease with most obviously rising trend is intertrochanteric fracturethe. c) The hospitalization cost per capita rises year by year, of which the constituent ratio of both material and examination costs grow obviously, but the operation, treatment and bed costs are still lower. It requires a multi-pronged approach to control the increase of hospitalization cost as well as the rationalization of cost constitution. d) Among all payment modes of hospitalization cost, the constituent ratio of patient’s own expense reduces year by year, while social security rises, indicating the medical security in national social security has been further expanded.
