Objective To Provide statistical references for disease-based payment reform with Diagnosis Related Groups (DRGs). Methods Based on 1 969 stroke inpatients from two hospitals in Chongqing city, we used classification and regression trees (CART) of decision tree to establish classification regulations of the case-mix model for stroke inpatients, and multivariate statistical model to evaluate whether the case-mix could provide a satisfactory prediction to costs for stroke inpatients in comparison with the foreign model. Results ① The classification nodes of our model were surgical procedure, nursing care degree, and hospital infection respectively by which 1 969 stroke inpatients were divided into 5 groups. The classification nodes in foreign model were surgical procedure, age≥50 years, and whether patients would refer to other institutions after leaving the hospitals by which 1 969 stroke inpatients were also classified into 5 groups. ② For medical institutions and the third payers, we found that the data from our model could explain 80.46% of the total costs and 16.58% for individual inpatient, which were higher than that of foreign model (76.87% for medical institutions and the third payers, 9.13% for individuals ). Conclusions Compared with foreign model, our model is more suitable for the situation in China. The study is only based on 1 969 stroke inpatients from south west part of China, so the conclusion needs further studies to confirm.
Abstract Objective To investigate the disease constitution and hospitalization expenses in Songqiao Central Township Health Center (SqC) in Gaoyou City of Jiangsu Province in 2010, so as to provide the baseline data of disease burden for further study. Methods The inpatient records of SqC in 2010 were collected. The first discharge diagnoses were classified according to the International Classification of Disease 10 (ICD-10). The general information of the inpatients, discharge diagnosis, hospitalization expenses, disease category, age, gender, and reimbursement of expenses were described and analyzed by using Microsoft Excel 2003 and SPSS 13.0 software. Results a) The total number of inpatients was 1036 in 2010, and the gender ratio was about 1.0 (50.7% vs. 49.3%); b) The disease spectrum included 17 categories. The cumulative percents of the top 5 systematic diseases were 81.2%, including the respiratory, digestive, neoplasm, circulatory diseases, and injury, poisoning amp; external causes; c) The top 15 diseases were pneumonia, fracture, malignant neoplasm, benign neoplasm, acute bronchitis, cerebral infarction, hypertension, acute appendicitis, emphysema, cholecystolithias accompanied with cholecystitis, inguinal hernia, coronary heart disease, diabetes mellitus, chronic bronchitis and superficial injury; d) The patients suffering from pneumonia and acute bronchitis were mainly over 65 years old and younger than 5; e) The number of chronic diseases significantly increased with age, especially after the age of 35 years old, and reached the peak at the age over 65 years old; while the acute diseases were mainly distributed at the age younger than 15 yeas old and older than 65 years old. The average length of stay, the total hospitalization and out-of-pocket expenses per capita of the chronic diseases were more than those of the acute ones (13.8 days vs. 9.9 days, ? 3 082 vs. ? 2 615; ? 417 vs. ? 371, respectively); f)The length of stay and total hospitalization per capita were quite higher than the other township health centers (11.6 days vs. 5.2 days, ? 3 001.4 vs. ? 1 004.6); and g) Both of the total reimbursement and out-of-pocket expenses per capita accounted for 44%-57% of the total hospitalization expenses. Among the total reimbursement, the payment from New Cooperative Medical Scheme (NCMS) accounted for over 99%, while that from Medical Aid Scheme only accounted for less than 2%. Conclusion a) The top 3 systematic diseases of SqC are seen in respiratory system, digestive system and neoplasm. The acute diseases are mainly pneumonia and fracture; b) The number of acute or chronic diseases increases significantly with age, especially after 35 years old. Both adolescents and the aged suffer from the heaviest burden of diseases; c) The average length of stay and hospitalization expenses pre capita of SqC are much higher than those of the other township health centers; and d) NCMS is the major source of reimbursement. However, the proportion of out-of-pocket expenses and the burden of diseases are still very high and heavy. Thus the policy of NCMS needs to be adjusted step by step in future.
Objective To analyze the influencing factors of hospitalization costs of obstructive hydronephrosis and explore the optimal grouping of diagnosis-intervention packet (DIP), so as to provide a basis for hospitals to strengthen the cost control of diseases, improve the level of refined management, and improve the compensation mechanism of DIP expenses by medical insurance departments. Methods The homepage data of medical records of Pingshan District People’s Hospital of Shenzhen City from January 2019 to December 2021 were collected, and the information of the discharged patients with the International Classification of Diseases-10th revision code as N13.2 was selected. The factors affecting hospitalization costs were analyzed by single factor analyses and multiple stepwise linear regression, the main surgical methods, number of other operations, and influencing factors of expenses were used as classification nodes, and the decision tree model was used to group and predict costs. Results A total of 1319 patients were included, the median inpatient expense was 10889.59 yuan, and the interquartile range was 10943.89 yuan. The case classification, days of hospitalization, condition of admission, whether it was hospitalized for the first time, whether clinical pathway was implemented, the way of discharge, the number of other diagnoses, and admission path were important factors affecting the inpatient expenses, and 12 groups of case mixes and corresponding expense standards were formed. The reduction in variance was 86.10%, the maximum coefficient of variation was 0.33, and the cost analysis ratio was 96.25%. Conclusions Combining the DIP grouping principle and the multi-factor grouping strategy of diagnosis-related groups, the grouping of obstructive hydronephrosis cases constructed by decision tree model is reasonable and the cost standard is close to reality. The case mixes and cost criteria can provide data support and decision-making reference for hospitals and medical insurance institutions.
ObjectiveTo analyze the clinical effects and hospitalization costs of the enhanced recovery after surgery (ERAS) mode for patients underwent radical resection of hepatocellular carcinoma (HCC). MethodThe clinicopathologic data of adult patients who underwent radical resection of HCC in the West China Hospital of Sichuan University from January 2017 to December 2019 were collected retrospectively. ResultsA total of 1 082 patients were collected according to inclusion and exclusion criteria in this study, including 469 patients in the ERAS mode group and 613 patients in the traditional mode group. There were no significant differences in baseline data such as gender, age, body mass index, preoperative complications, operation type, and medical group between the two groups (P>0.05). Compared with the traditional mode group, the total hospitalization cost, medical service fee, examination fee, bed fee, and cooling and heating fee in the ERAS mode group were lower (P<0.05), the average total hospitalization time was shortened by about 1.2 d (P<0.01), the preoperative hospitalization time was shortened by about 0.3 d (P=0.03), and the postoperative hospitalization time was shortened by about 0.8 d (P<0.01) in the EARS mode group. There were no significant differences in the incidences of specific complications and total complications between the two groups (P>0.05). ConclusionERAS for patients with HCC might play a role in improving rehabilitation efficiency and reducing hospitalization costs.
Objective To provide references to control the cost of stroke inpatients by analysing pertinent factors of stroke inpatients. Methods According to the models of Anderson and Newnan, univariable analysis and multivariable statistical analysis were applied to a number of factors including predisposing factors, enabling factors, and needs factors in 1 969 stroke inpatients of two third level first-class hospitals in Chongqing. Results Among the 1 969 stroke inpatients, 64% had a history of hypertension, and 50% exhibited hypertension during their stay in hospital. Expenditure on medication consumed the highest costs (51%). Length of stay was the most important factor affecting inpatient expense, additional factors were number of surgical operation, nurse type, Rankin score, number of complications etc. Conclusions Complex measures focusing on hypertension to prevent and control of stroke are recommended. Reducing unnecessary stay in hospital and appropriate prescribing are important methods to reduce cost of stroke inpatients.
Objective To investigate the disease constitution and cost of inpatients in Gaozha Central Township Health Center (GzC) in Wuzhong City of Ningxia Hui Autonomous Region from 2008 to 2010, so as to provide baseline data for further research. Methods A questionnaire combined with a special interview was carried out, and case records and cost information of GzC inpatients in 2008, 2009 and 2010 (from January to November) were collected. The diseases in discharge record were classified according to International Classification of Diseases (ICD-10) based on the first diagnose and the cost was analyzed. Data including general information of the inpatients, discharge diagnosis, hospitalization expenses, and drug cost etc. were rearranged and analyzed by Excel software. Results a) The total number of the inpatients was 1124, 642 and 747 in 2008, 2009 and 2010, respectively. The female was more than the male in both 2008 (59.34% vs. 40.66%) and 2009 (60.75% vs. 39.25%), and their disease spectrum included 17 categories, which accounted for 81% of ICD-10; b) The top six most commonly seen systematic diseases with a constituent ratio from 86.63% to 92.06% in recent three years were as follows: the respiratory system, digestive system, circulatory system, genitourinary system, injury and toxicosis, skeletal musculature and connective tissue disease. Except the injury and toxicosis, the other five systematic diseases were commonly seen in females rather than in males; c) The top 15 monopathies in recent three years were pulmonary infection, tracheitis or bronchitis, coronary heart disease, soft tissue injury, gastritis or chronic gastritis, upper respiratory infection, hypertension, urinary tract infection, prolapse of lumbar intervertebral disc, pelvic inflammation, fracture, pneumocardial diseases, superficial injury, chronic cholecystitis and arthritis; d) The main burdens of disease for inpatients focused on 35-54 age groups, then followed by the age groups above 55 in 2008 and 2009. Except the injury and toxicosis, the other diseases were commonly seen in females rather than in males. Pulmonary infection focused on the age groups above 35; the onset of hypertension increased obviously and a sharp rise of hypertension existed in the 45-54 age groups in 2008, but the hypertention focused on 35-44 age groups in 2009; e) The total inpatients with top 15 monopathies accounted for 64.06% to 71.21%, including 8-9 chronic diseases ranking higher in 2010, and 6-7 acute diseases focusing on infection and injury; and f) The average costs of chronic diseases were higher than those of acute diseases. Conclusion a) There is a big gap between GzC and Yong’an Central Township Health Center (YaC) regarding the level of the regional economic development, the situation of disease burden and cost of inpatients. The former is demonstrated as general Central Township Health Center, while the latter as affluent Central Township Health Center in western China; b) In recent three years, the main systematic diseases are in respiratory, circulatory and digestive system; the inpatients suffer from more chronic diseases rather than acute diseases in their young age; the acute diseases mainly include infection and injury, and the pulmonary infection has ranked as the first during the past three years; c) The inpatients in 2008 and 2009 are mainly in ages of 35 to 54, and then are over 55 years old. Except the injury and toxicosis, the other diseases were commonly seen in females rather than in males; d) The patients’ average costs of chronic diseases for hospitalization and drug in 2010 were lower than those of YaC. Consideration on reasonable constitution of the cost for hospitalization should be paid attention to; and e) It is urgent to strengthen the construction of infrastructure and informatization in GzC.
Objective To Investigate the disease constitution and hospitalization expense in Luxi township health center (LxC) in Yongxi county of Jiangxi Province in 2010, to make clear about the local burden of diseases and to provide the baseline data for further study. Methods The inpatient records of LxC in 2010 were collected. Based on the primary diagnosis on hospital discharge record, the diseases were standardized and classified according to the International Classification of Disease, 10th Edition (ICD-10). Data including general information of the inpatients, discharge diagnosis, hospitalization expense and usage of essential medicine etc, were reorganized and analyzed by using Microsoft Excel 2003 and SPSS 13.0 software. Results a) The total number of inpatients were 925 in 2010, with male/female ratio of 0.8; b) The disease spectrum included 17 categories, accounting for 81% of the ICD-10; c) The top 5 diseases were in respiratory, digestive, injury, poisoning amp; external causes, circulatory and genitourinary system, totally accounting for 82.27%; d) The top 15 single diseases were upper respiratory infection, fracture, chronic obstructive lung disease (COPD), chronic gastroenteritis, cerebrovascular disease (CVD), calculi in urinary system, rheumatoid arthritis, intervertebral discs diseases, cholecyslithiasis accompanied with cholecystitis, cardiac disease, reproductive organ diseases, injury amp; poisoning, pneumonia, hypertension and peptic ulcer; e) The patients with upper respiratory infection and pneumonia were mostly older than 65 or younger than 5 years old. With the exception of calculi in urinary system and peptic ulcer, all the other 8 chronic diseases were mainly seen in patients over 65 years old; f) Among the 15 single diseases as listed above, the chronic diseases were associated with shorter average hospital stay and low average expense compared with the acute diseases (4.8 d vs. 11.6 d; ?439.1 vs. ?666.9); and g) The hospitalization expense of LxC, although increasing year by year, was still far below that of the national township health centers (?542.3 vs. ?1 004.6). Conclusion a) The top 3 in inpatients systematic diseases of LxC are respiratory system, digestive system, and injury and poisoning; the former 2 diseases attack more often in females, and the acute diseases are mainly infection and fracture; b) Except for rheumatoid arthritis, cholecyslithiasis accompanied cholecystitis, cardiac diseases, reproductive organ diseases and peptic ulcer, all the other 10 of the top 15 single diseases are similar to Yong’an township health center (YaC) in Sichuan Province in 2010; c) The acute diseases mainly focus on respiratory system, and injury and poisoning, and the chronic diseases mainly focus on digestive system, circulatory system, genitourinary system, the musculoskeletal system and connective tissue system; d) The number of patients who suffer from chronic diseases increases significantly when over of 35 years old, especially, often seen in female rather than male. The acute burden diseases is serious in patients less than 15 or more than 45 years old; e) The upper respiratory infection and pneumonia mainly affect the old and children; f) Compared with Xintian township health center (XtC) in Gansu Province, the average hospital stay of fracture patients is longer (43.7 d vs. 9.0 d), the hospitalization expense is higher (?1 948.0 vs. ?1 648.3), and the diseases is burden heavier (8.1% vs. 4.9%); and g) The average hospital stay of patients with acute diseases is longer than YaC and XtC (11.6 d vs. 3.7 d, 6.2 d), but the hospitalization expense is lower than both of them (?666.9 vs. ?850.4, ?906.9).
Objective To explore the subdivision method of diagnosis-related group (DRG) by case-mix payment, and provide reference for reasonable imbursement mechanism and standard for DRG grouping, as well as disease cost accounting and performance assessment for hospitals. Methods The first page data of medical records of 17010 inpatients with uterine fibroids in Obstetrics and Gynecology Hospital of Fudan University from 2019 to 2021 were included. Based on the disease and treatment, combined with the length of hospital stay, other diagnosis and other factors, nonparametric test and generalized linear model were used to explore the factors affecting hospitalization expenses. Decision tree model was performed to yield case-mix related groups and predict the cost. Results The inpatients with uterine fibroids were classified into 13 groups in decision tree model based on the main surgical methods, other surgical types, and length of hospital stay. The reduction in variance was 0.34, and the coefficient of variation was 0.19-0.88. Conclusions The case-mix payment approach based on the decision tree model as the grouping method is more consistent with the actual clinical diagnosis and treatment of uterine fibroids, and can be used as method reference for the subdivision of DRG. Under the background of DRG, subdivision of DRG can provide decision-making basis for refined hospital management, including in-hospital cost accounting and performance allocation.
