Combined with DRGs payment mode, under the guidance of the diagnosis operation selection standard announced by the Health Development Planning Commission and the Principles of International Classification of Diseases, selfcheck and retrospective analysis were conducted, and the defects were classified and counted with 6 cases of high rate paying.Results Totally 111 of 526 high rate cases had defect problems related to clinicians and coders, with defective rate 21.11%, and among them, 47, 20, 12 and 29 cases were clinicians' main diagnostic error selection, main operation error selection , main diagnosis and operation error selection, and missing of diagnosis or operation, respectively. The percentage of errors was 42.34%, 18.02%, 10.81% and 26.13% respectively. The coders' main diagnosis coding error and main surgical coding error were 2 and 1 cases respectively, with error rate 1.8% and 0.9% respectively.Conclusion The high rate paying cases caused by the defects of the filling diagnosis and operation and the coding defects on the front page of medical records were closely related to the quality of filling by clinicians and the coding level of coders. Effective measures are to train clinicians to correctly select diagnosis and operation, improve coders' professional skills, and optimize coders' work, so as to reduce high rate cases caused by defective problems.

Objective To explore the relationship between sleep quality and well-being in the elderly and the intermediary effect of state-anxiety between them. Methods One hundred and fifty-five elderly patients with insomnia in the department of psychosomatic medicine of the First Affiliated Hospital of Nanchang University from September 2018 to May 2019 were investigated with Pittsburgh sleeping quality index (PSQI), state-trait anxiety questionnaire (STAI) and memorial university of Newfoundland scale of happiness (MUNSH). Results The STAI score of female patients was higher than that of male patients, and the MUNSH score of patients living alone was lower than that of non-living alone patients (P<0.05). Sleep quality index score was negatively correlated with well-being (r=-0.557, P<0.05), state-trait anxiety was negatively correlated with well-being (r=-0.634, P<0.05), and state-trait anxiety was positively correlated with sleep quality index score (r=0.510, P<0.05). Structural equation model showed that sleep quality had a negative effect on happiness (β=-0.28, P<0.05) and a positive effect on state-trait anxiety (β=0.70, P<0.05), and state-trait anxiety had a negative effect on well-being (β=-0.64, P<0.05). Conclusion State-trait anxiety plays an intermediary role in elderly patients with insomnia. Sleep quality not only directly affects happiness, but also affects the happiness of elderly patients with insomnia through state-trait anxiety.

Objective There are more variant subtypes of thyroid papillary carcinoma, which cause difficult coding of thyroid papillary carcinoma and are prone to miscoding. According to the histological classification criteria of thyroid tumors and the ICD-O-3 principle, the coding characteristics of thyroid papillary carcinoma are analyzed to improve the coding accuracy rate. Methods  The hospital medical record information inquiry system was used to retrieve 417 cases of thyroid papillary cancer diagnosed from January 2016 to December 2018 in a hospital. The ICD-O-3 classification rule was used to analyze the morphological coding situation of thyroid papillary carcinoma in a hospital for nearly 3 years. The existing problems were summarized and analyzed. Results There were 159 coding errors and the error rate was 38.13%. Among them, 2 cases of NOS were misclassified in M8000/3 malignant tumor, accounting for 0.48%; 149 cases were misclassified in M8050/3 papillary carcinoma, accounting for 35.73%; the disease classifier was not familiar with the pathological variant subtype of papillary thyroid carcinoma. Pathological diagnosis had given specific subtypes, but was misclassified in M8260/3 papillary adenocarcinoma in 8 cases, accounting for 1.92%; missing morphological morphology was 1 case, accounting for 0.24%.Conclusion Disease classifiers are unfamiliar with the pathological features and variant subtypes of thyroid papillary carcinoma, lack the homepage quality control link, and the coding library is relatively lagging behind clinical development. These reasons are likely to cause coding errors, so disease classification personnel must carefully read the medical records and pathology reports, actively communicate with clinicians and patho logists, update relevant knowledge structures, and continuously improve the accuracy of thyroid papillary cancer coding.

Objective To improve the ability of traditional Chinese medicine(TCM) medical service by retrospectively describing and analyzing the clinical diagnosis and treatment characteristics of discharged patients treated mainly by  TCM in a hospital.Methods Discharged patients were divided into the TCM dominant group and the non-TCM dominant group for analysis and comparison, according to the requirement of national performance assessment indicators.Results The differences in population distribution and cost between the two groups were statistically significant (P＜0.05); the number of discharged patients and the proportion of TCM dominant patients were higher for diseases such as posterior circulation ischemia, malignant tumor support treatment and lumbar intervertebral disc herniation; the proportion of DRG group diseases was high, such as alzheimer′s disease or other chronic brain function lesions, coronary atherosclerosis without complications and concomitant diseases.Conclusion Discharged patients treated mainly by TCM had a significant cost advantage, but the average hospitalization days were longer; the diseases with high proportion and high number of TCM dominant discharged patients can be candidate diseases of TCM superiority. It is necessary to actively explore the DRG management scheme in accordance with the characteristics of TCM therapy.

This article analyzes and elaborates on the connotation of elderly health, the narrow and broad content of elderly health services, as well as safeguard measures. Meanwhile, it combines with long-term practical experience and practice to establish and improve the elderly health service system with a large amount of data and examples.

Many diseases in ophthalmology are named after people's names. These diseases are usually named after foreign ophthalmologists who reported the disease for the first time. Clinicians often use English names directly as the diagnosis of these diseases, such as Coats′ disease, Fuchs syndrome, Leber's hereditary optic neuropathy, Duane syndrome, etc. In order to search for the correct codes of these diseases, this paper explores the coding search methods of these ophthalmic diseases, and finds that their codes are H35.0, H20.8, H47.2 and H50.8, respectively. It is concluded that there are generally two methods of selecting leading words for disease coding named by human names: name and clinical manifestations. Choosing persons' names as leading words requires searching for the authoritative Chinese transliteration names of these foreign ophthalmologists in the literature, and using authoritative Chinese transliteration names as leading words to search for codes; choosing clinical manifestations as leading words requires a full understanding of the etiology, development, diagnosis, treatment and prognosis of these diseases in the medical literature, to grasp the clinical manifestations of these diseases.

Objective To evaluate the bed efficiency index after correction of each month and each department of a tertiary hospital in 2018, to analyze the reasons for its high efficiency or low efficiency operation, and analyze the influencing factors of the adjusted bed efficiency index, so as to provide reference for the rational allocation of beds in the hospital. Methods The "normalization method" was adopted to calculate the bed efficiency index of each month and each department of a tertiary hospital in 2018, and the CD rate was used for correction.Multiple linear regression method was used to analyze the influencing factors of bed efficiency index after correction. Results For the beds efficiency index in every month, the highest was in July and the lowest was in February.Indexes in every month except that in February were all higher than 0.9.In the adjusted bed efficiency index of all departments, while some department beds were running with high efficiency, there were also some departments with vacant beds. The efficiency index of ICU was the highest (4.06). The linear regression analysis found that the higher the initial number of patients, the number of patients admitted, and the number of patients undergoing two or three types of incision surgery, the higher the emergency admission rate, the higher the bed efficiency index after correction, and the higher the bed efficiency. The more cases of grade 3 and 4 operations, the lower the bed efficiency index. Conclusion Reasonable allocation of hospital beds could be carried out efficiently through administrative intervention and the improvement of medical service mode, and through making use of affecting factors of bed efficiency index.

Objective To understand the current status and hotspots of DRG research in China in order to provide reference for the focus and direction of subsequent research.Methods The literatures related to DRG were retrieved from China National Knowledge Network (CNKI). Descriptive analysis was made on the number of DRG literatures and the years of publication. Social network analysis was used to analyze the core authors, cooperative groups, high-frequency keywords and their relationships in DRG literatures.Results There were 2 602 journal articles with the theme of ‘DRG’ or ‘diagnosis related groups’. After 2015, the number of DRG literatures in China showed a multiple increase, with the annual literatures in 2021 and 2022 exceeding 500. There were 1 072 articles from core journals (41.20%) and 1 530 articles from non-core journals (58.80%). There were 188 core authors in the field of DRG research, mainly forming 7 cooperative groups led by Hu Mu and Guo Moning, with a total of 1 425 publications (54.77%). The network cograph and centrality analysis of high-frequency keywords showed that payment method, DRG prepaid, first page of medical records , hospital management, hospitalization cost and performance evaluation were the high-frequency keywords in the field of DRG research, and their point degree centrality and proximity centrality ranked first. However, the first page of medical records and CMI were more mediation-centered.Conclusion The number of literatures in the field of DRG research increases rapidly in recent years, but the quality of literatures needs to be evaluated and improved. The core authors are relatively concentrated and have strong overall influence and academic leading role. The research hotspot of DRG focuses on DRG payment and DRG performance evaluation and hospital management.

Objective To analyze the characteristics, influencing factors and potential risks of adverse drug reactions (ADR) in a tertiary psychiatric hospital, so as to provide reference for clinical prevention and disposal of adverse drug reactions of psychotropic drugs.Methods A retrospective analysis was conducted on 265 ADR case reports due to the use of psychotropic drugs reported by a psychiatric hospital from October 2019 to October 2021.Results Among the 265 reported cases with ADR, 88 were males and 177 were females, with a higher incidence among females. The average age of the patients was (42.23±17.54) years old, with the majority being young and middle-aged. Forty drugs were involved in ADRs reports, of which the number of adverse reaction reports of antipsychotics was the largest, accounting for 66.42%, followed by antidepressants, accounting for 20.38%. The top three drugs in the cumulative number of reported ADR cases were Olanzapine, Quetiapine and Risperidone respectively. The system most affected by ADRs was the digestive system, with 105 cases reported, accounting for 37.23%, followed by the nervous system, with 88 cases reported, accounting for 31.21%.Conclusion The forms of adverse reactions caused by psychiatric drugs are various, and it is difficult to identify them. Clinicians should strengthen the monitoring of the use of psychiatric drugs and use the psychiatric drugs reasonably to ensure the medication safety.

Objective To explore the risk factors of diabetic nephropathy complicated with proteinuria, and provide evidence for relevant departments to develop preventive measures.Methods Totally 92 patients with diabetes mellitus admitted to a hospital from July 2016 to December 2018 were enrolled. Selfmade questionnaires were used to collect patientrelated data and laboratory tests and multivariate logistic regression was used to screen for risk factors for diabetic nephropathy complicated with proteinuria.Results Among 92 patients with diabetes, 28 cases of diabetic nephropathy with proteinuria, the incidence rate was 30.43%. Multivariate logistic stepwise regression analysis showed that the course of disease (OR=2.195), BMI (OR=1.634), LDL-C (OR=1.829), TG (OR=1.259), HbAlc (OR=1.642), UA (OR= 1.579) and hypertension (OR=1.381) were risk factors for diabetic nephropathy with proteinuria (P<0.05).Conclusion Active health education, shortening the course of disease, reduction of body weight, and control of blood pressure and blood lipids can reduce the incidence of diabetic nephropathy with proteinuria.

Objective To reconstruct the infant mortality rate from the liberation to the late 1970s in China. Methods According to the time sequence, based on the adjusted infant mortality rate of 1981-1990s and national monitored area infant mortality rate of 1991-2010s, we brought in infant mortality rate of 1949-1980s to establish the relative time series for curve fitting. We preliminary screened the multiple prediction models of infant mortality of 1949-2010s, then secondary screened better dynamic model by using the curve fitting of variance analysis, and at last, we found the best prediction model according to the curve fitting accuracy index, for further retrospective prediction of the infant mortality of 1949-1980. Results Eleven dynamic models of infant mortality rate in China were selected, then we screened out the poor fit models. We found out the exponential form, compound functional, growth functional and logistic curve model, were consistent with the predicted results and the standard error of the estimated value was smallest. They were determined the best prediction model. By prediction the infant mortality rate of 1951, 1956, 1961, 1966, 1971, 1976, and 1980 were 170.5‰,140.7‰, 183.0‰, 95.8‰, 79.1‰, 65.2‰, and 55.9‰ respectively. Conclusion Reconstructed infant mortality rate could not replace the actual level, but more close to the actual level.

Objective To investigate the related factors affecting the occurrence of acute illness during root canal treatment. Methods Totally 500 patients who underwent root canal therapy in our hospital from January to January 2019 were enrolled. According to the patients′ EIAE condition, Univariate analysis and multivariate logistic regression analysis were used to analyze differences in age, gender, tooth position, sinus tract, total flushing dose, disinfecting drug, root filling method, and root filling and the influencing factors inducing the occurrence of acute illness during root canal treatment. Results EIAE occurred in 168 of the 500 patients, with an incidence of 33.6%. Univariate analysis found that EIAE patients had differences in sinus tract, total flushing dose, root filling method, and root filling (P<0.05), compared with non-EIAE patients. There was no difference in age, gender, tooth position and disinfection drug (P>0.05). Multivariate logistic regression analysis showed that the risk factors of EIAE were: no sinus tract, 2 mL of total drug washing and below, multiple root filling and overcharging. And the goodness of fit of this model indicated an outstanding fitting (AUC=0.917).Conclusion Thoroughly cleaning the root canal, improving the filling quality, and improving the disposable root canal treatment method can reduce the occurrence of EIAE.

目的 探讨协同护理管理中应用同伴支持对心内科患者自我管理能力的影响。 方法根据是否有亲友被招募为同伴,选取2013年5月~2015年6月入住我院心内科患者60例作为支持组,并选取同期入住患者62例作为管理组,管理组患者实施协同护理管理,支持组患者在协同护理管理的基础上加入同伴支持,调查比较两组患者管理前及管理6个月后的自我管理能力评分、生活质量评分及对护理工作的满意度情况。 结果管理前,两组患者自我管理能力各项指标评分、生活质量各项指标评分差异均无统计学意义(P>0.05)。管理6个月后,两组患者上述各项指标均高于管理前。组间比较,管理后支持组自我管理能力各项指标评分、生活质量各项指标评分均高于管理组,且两组管理前后自我管理能力各项指标评分、生活质量各项指标评分差值对比,差异具有统计学意义(P<0.05)。两组护理满意度比较差异无统计学意义(P>0.05)。 结论协同护理管理可提高心内科患者的管理效果,在此基础上加入同伴支持可进一步提高心内科患者自我管理能力、生活质量,值得临床推广。
