RESUMO
PURPOSE OF REVIEW: This paper briefly introduces the status quo of bariatric and metabolic surgery and medical insurance payment in China. RECENT FINDINGS: Along with China's rapid economic growth, the prevalence of obesity and diabetes is increasing quickly. Because of their high body fat percentage and predominance of abdominal obesity, Chinese people experience metabolic disorders more frequently than Caucasians with the same BMI. Treatments are not medical because there is a lack of social understanding of obesity. Furthermore, obesity has not been accepted as a disease in China and so has not been included in the medical insurance payment system. Therefore, weight-loss medications are not covered by medical insurance. In China, bariatric and metabolic surgery have advanced for almost 20 years, and corresponding guidelines have been developed. However, there are regional and cognitive variations in whether medical insurance covers bariatric surgery or not. Recent research on the financial advantages of medical insurance coverage for weight-loss surgery showed that it conserves healthcare system resources. It will be important to raise public awareness regarding obesity in the future, present more evidence of the clinical efficacy of surgery, and work towards a higher percentage of medical insurance reimbursement for obesity treatment and bariatric surgery.

COVID-19 causes persistent symptoms such as weakness and myasthenia in most patients. Due to the cross-infection of COVID-19, the traditional face-to-face rehabilitation services are risky for the elderly. To ensure that the elderly in urgent need of rehabilitation services receive training while minimizing the disturbance of the COVID-19 pandemic on their social activities. We have improved the existing virtual upper limb training system, and added a social factor to the system. Seniors with upper limb rehabilitation needs can use the system to compete or collaborate with others for training. In addition, a set of natural and scientific exclusive gestures have been designed under the direction of following the doctor's advice. The experiment is conducted jointly with the chief physicians of the geriatrics department in the authoritative class-A hospitals of Class III. Our experiment, which lasted for two months, showed that the virtual training system with social factors added had the best rehabilitation effect and enhanced the initiative of patients. The system has value for popularization during the COVID-19 epidemic.
RESUMO
AIMS: The number of ventilator-dependent patients is rapidly increasing globally. As a result, long-term mechanical ventilation (LTMV) patients face the choice of receiving health care in respiratory care wards (RCWs) rather than at home. In this study, we applied Andersen's behavioral theoretical model (ABM) to investigate the determinants of the health care service decisions of patients receiving LTMV. METHODS: A cross-sectional research design and cluster random sampling were used to select 365 participants from nine RCWs and eight home care facilities in northern Taiwan. Data were collected in face-to-face interviews using a structured questionnaire. RESULTS: Of the predisposing factors, advanced age and an education level of at least junior high school influenced the choice to use RCW services. Being married, living with extended family, and medium or higher socioeconomic status were associated with the decision to use home care services. Of the enabling factors, patients with more caregivers, those whose family caregivers held strong beliefs about providing care, and those who perceived greater social support from health care providers were more likely to choose home care services. Of the need factors examined, poor cognitive function and higher dependence on assistance for activities of daily living (ADL) increased the probability of patients choosing RCW services. Hierarchical logistic regression analysis indicated that our final model accounted for 44.8% of the observed variance in health care service choice. CONCLUSIONS: ABM enables an improved understanding of the health care service choices of LTMV patients. Our findings also highlight the importance of rigorously assessing patient needs and helping patients choose the most appropriate health care service.

BACKGROUND: This systematic review and meta-analysis aimed to estimate the pooled prevalence of dysphagia in older adults, subgrouping by recruitment settings and varying dysphagia assessment methods. METHODS: Five major databases were systematically searched through January 2022. A random-effects model for meta-analysis was conducted to obtain the pooled prevalence. RESULTS: Prevalence of dysphagia in the community-dwelling elderly screened by water swallow test was 12.14% (95% CI: 6.48% to 19.25%, I2 = 0%), which was significantly lower than the combined prevalence of 30.52% (95% CI: 21.75% to 40.07%, I2 = 68%) assessed by Standardized Swallowing Assessment (SSA) and volume-viscosity swallow test (V-VST). The dysphagia prevalence among elderly nursing home residents evaluated by SSA was 58.69% (95% CI: 47.71% to 69.25%, I2 = 0%) and by the Gugging Swallowing Screen test (GUSS) test was 53.60% (95% CI: 41.20% to 65.79%, I2 = 0%). The prevalence of dysphagia in hospitalized older adults screened by the 10-item Eating Assessment Tool was 24.10% (95% CI: 16.64% to 32.44%, I2 = 0%), which was significantly lower than those assessed by V-VST or GUSS tests of 47.18% (95% CI: 38.30% to 56.14%, I2 = 0%). CONCLUSIONS: Dysphagia is prevalent in the elderly, affecting approximately one in three community-dwelling elderly, almost half of the geriatric patients, and even more than half of elderly nursing home residents. The use of non-validated screening tools to report dysphagia underestimates its actual prevalence.
RESUMO
Intracranial aneurysms (IAs) remain a major public health concern and endovascular treatment (EVT) has become a major tool for managing IAs. However, the recurrence rate of IAs after EVT is relatively high, which may lead to the risk for aneurysm re-rupture and re-bleed. Thus, we aimed to develop and assess prediction models based on machine learning (ML) algorithms to predict recurrence risk among patients with IAs after EVT in 6 months. Patient population included patients with IAs after EVT between January 2016 and August 2019 in Hunan Provincial People's Hospital, and an adaptive synthetic (ADASYN) sampling approach was applied for the entire imbalanced dataset. We developed five ML models and assessed the models. In addition, we used SHapley Additive exPlanations (SHAP) and local interpretable model-agnostic explanation (LIME) algorithms to determine the importance of the selected features and interpret the ML models. A total of 425 IAs were enrolled into this study, and 66 (15.5%) of which recurred in 6 months. Among the five ML models, gradient boosting decision tree (GBDT) model performed best. The area under curve (AUC) of the GBDT model on the testing set was 0.842 (sensitivity: 81.2%; specificity: 70.4%). Our study firstly demonstrated that ML-based models can serve as a reliable tool for predicting recurrence risk in patients with IAs after EVT in 6 months, and the GBDT model showed the optimal prediction performance.

As a persistent organic pollutant, pentachlorophenol (PCP) has serious impacts on human health. However, its presence in animal source food products sold in the Guangdong Province (GD) of China, and the resultant dietary exposure have not been elucidated. To address this gap, 3,100 samples from seven food categories, including beef, pork, mutton, offals, broilers, hen eggs, and farmed freshwater fish, marketed throughout four geographical regions of GD, were collected from 2015 to 2018. Gas chromatography coupled with mass spectrometry was employed to detect PCP levels in these food matrices. PCP was found in all food categories, but the average contamination levels were low, ranging from 0.40 µg/kg wet weight (ww) (hen eggs) to 5.85 µg/kg ww (offals). However, higher concentrations of PCP were detected (P < 0.05) in animal source food from the North region. Additionally, a temporal declining trend was observed in this four-year consecutive survey. The estimated human dietary exposure of PCP to population groups, including the general population and subgroups (male and female, children, and adults), was found to be far below the permissible daily intake (3 µg/kg body weight). Therefore, the health impacts of PCP should be correspondingly low for local residents, based on current toxicological knowledge. Regional exposure patterns varied due to different extents of contamination in the four areas, and pork, broilers, and freshwater fish were the major sources of dietary PCP exposure. PRACTICAL APPLICATION: As a persistent organic pollutant, pentachlorophenol (PCP) has serious impacts on human health. However, its presence in animal source food products sold in Guangdong Province of China, and the resultant dietary exposure have not been elucidated. In this study, we conducted an in-depth investigation on the occurrence of PCP in major foodstuff categories, including beef, pork, mutton, broilers, offals, hen eggs, and farmed freshwater fish, marketed in all 21 prefecture-level divisions of Guangdong Province, in order to provide integral insights for regulatory authorities.

PURPOSE: Nurse practitioners (NPs) are increasingly important in healthcare as they play a key role in leading advanced nursing practices. Assessing their professional competence is essential. The aim of this study was to evaluate NPs' professional competencies based on at a collaborative model around NP self and compare different methods of assessment. METHODS: This is a cross-sectional study, and a purposive sample of 211 participants in the teaching hospital was used. Methods used were self-assessment (nurse practitioners), peer assessment (physicians and nurses) and supervisor assessment (head nurses). RESULTS: The competence of nurse practitioners was rated as moderate (mean score = 3.45 of a possible 5; SD = 0.59). However, each method resulted in differences in competence for total scores and dimensions. The highest competence was in direct patient care (mean = 3.55, SD = 0.53), and the lowest score was in monitoring the quality of patient care (mean = 3.30, SD = 0.82). post hoc analysis shown that supervisor assessment rated professional competence significantly lower than the method of self-assessment and peer assessment (F = 10.07, p < .001). CONCLUSION: NPs require an increased effort to continuous learning for enhancing professional competencies. Moreover, using multiple methods for assessment to obtain a more comprehensive and accurate evaluation of NPs' professional competence.

Objectives: Exploring determinants underlying disparities in full vaccination coverage (FVC) can contribute to improved immunization interventions. FVC and its risk factors in Zhejiang province have been studied, yet the determinants explaining the rural-urban disparity in FVC have not been studied. This study aimed to disentangle the factors explaining rural-urban disparities in FVC of vaccine doses scheduled during the first year of life in Zhejiang province. Methods: We used data from a vaccination coverage survey among children aged 24-35 months conducted in 2016. The outcome measure was full vaccination status, and the grouping variable was the area of residence. Descriptive statistics were used to analyze the FVC and rural-urban residence across the exposure variables. The Fairlie decomposition technique was used to decompose factors contributing to explaining the FVC disparity. Results: There were 847 children included in this study, of which 49.6% lived in a rural area. FVC was 94% in rural areas and 85% in urban areas. A disparity of 9% to the advantage of the rural areas and the exposure variables explained 81.1% of the disparity. Maternal factors explained 49.7% of the explained disparity with education, occupation, and ethnicity being the significant contributors to the explained disparity. Children's birth order and immigration status contributed somewhat to the explained inequality. Conclusion: There was a significant disparity in FVC in Zhejiang province, a disadvantage to the urban areas. Policy recommendations or health interventions to reduce the inequality should be focused on eliminating poverty and women's illiteracy, targeted at migrant children or children from minority ethnicities.

AIMS/INTRODUCTION: The present study estimated the cost-effectiveness of bariatric surgery versus medication therapy for the management of recently diagnosed type 2 diabetes mellitus (T2DM) in obese patients from a Chinese health insurance payer perspective. MATERIALS AND METHODS: A Markov model was established to compare the 40-year time costs and quality-adjusted life-years (QALYs) between bariatric surgery and medication therapy. The health-care costs in the bariatric surgery group, proportion of patients in each group with remission of diabetes, and state transition probabilities were calculated based on observed resource utilization from the hospital information system (HIS). The corresponding costs in the medication therapy group were derived from the medical insurance database. QALYs were estimated from previous literature. Costs and outcomes were discounted 5% annually. RESULTS: In the base case analysis, bariatric surgery was more effective and less costly than medication therapy. Over a 40-year time horizon, the mean discounted costs were 86,366.55 RMB per surgical therapy patient and 113,235.94 CNY per medication therapy patient. The surgical and medication therapy patients lived 13.46 and 10.95 discounted QALYs, respectively. Bariatric surgery was associated with a mean health-care savings of 26,869.39 CNY and 2.51 additional QALYs per patient compared to medication therapy. Uncertainty around the parameter values was tested comprehensively in sensitivity analyses, and the results were robust. CONCLUSIONS: Bariatric surgery is a dominant intervention over a 40-year time horizon, which leads to significant cost savings to the health insurance payer and increases in health benefits for the management of recently diagnosed T2DM in obese patients in China.

This study aimed to investigate the coverage of hepatitis B vaccine (Hep B) and its completeness and timeliness for birth cohorts from 1999 to 2017 in Zhejiang province, East China. Demographic characteristics and vaccination records of Hep B of children born from 1 January 1999 to 31 June 2017 were extracted from the Zhejiang provincial immunization information system. The timeliness of the first dose of Hep B (Hep B1) was defined as the proportion of children who received the Hep B1 within 24 h after birth among the target population. The completeness of Hep B was defined as the proportion of children who completed the three-dose series of Hep B before 7 years of age. The demographic characteristics of the target population were described. The coverage of each dose of Hep B, the timeliness of Hep B1, and the completeness of Hep B for each birth cohort were described. A logistic regression model was applied to detect the determinants of the timeliness of Hep B1 and the completeness of Hep B vaccination. The coverage of Hep B1 increased from 90.3% to 98.3%, the coverage of Hep B2 increased from 88.8% to 96.1%, and the coverage of Hep B3 increased from 86.4% to 94.2%. The timeliness of Hep B1 increased from 80.3% to 91.3%. The completeness of Hep B increased from 81.3% to 91.5%. The determinants of timeliness of Hep B1 included children's delivery place, immigration status, maternal education level, and economic development level of resident area. The determinants of completeness of Hep B included children's delivery place, immigration status, maternal education level, economic development level of resident area, maternal occupation, and frequency of vaccination service. Zhejiang province had achieved significant improvements in the timely administration of Hep B1 and the completeness of Hep B. To accelerate progress toward additional reductions in the transmission of hepatitis B virus, further efforts need to be focused on improving the timeliness of Hep B1 vaccination and reducing the drop-outs among disadvantaged children with the risk factors identified in this study.

BACKGROUND: This study was aimed to assess the coverage of two doses of measles vaccine and identify the determinants of the delayed vaccination. METHODS: A cluster survey among 1386 children aged 24-35 months was conducted. Characteristics on demographic and socio-economic and vaccination records was collected. The overall coverage was defined as the proportion of children receiving the first dose of measles vaccination and the second dose of measles vaccination by 24 months of age. The age-appropriate coverage was defined as the proportion of children receiving the measles vaccine doses within one month after its relevant due date. Timeliness was evaluated with the Kaplan-Meier analysis. Cox proportional hazard regression was adopted to identify determinants of the delayed vaccination. RESULTS: The overall coverage was 96.9% for the first dose of measles vaccine and 93.9% for the second dose of measles vaccine. The age-appropriate coverage of the first and the second dose of measles vaccine was 76.6 and 68.2%, respectively. Household having more than one child, non-local children were associated with the delayed vaccination for the first and the second dose of measles vaccine. Children delivered at home, younger mothers, low maternal education background, mothers with a fixed job, and low household income were associated with the delayed vaccination for the second dose of measles vaccine. CONCLUSIONS: The coverage of measles vaccine had been improved for both the first and the second dose, while the timeliness still needed improvement. We suggested the policy-makers pay more attention to the reasons for non-vaccination and determinants of delayed vaccination when planning efforts to ensure the high age-appropriate coverage of measles vaccination.

Objective: The objectives of this study were to determine the degree and risk factors of the inequity in the childhood coverage of full primary immunization (FPI) in Zhejiang province. Method: We used data from two rounds of vaccination coverage surveys among children aged 24â»35 months conducted in 2014 and 2017, respectively. The household income per month was used as an index of socioeconomic status for the inequality analysis. The concentration index (CI) was used to quantify the degree of inequality, and the decomposition approach was applied to quantify the contributions from demographic factors to inequality in the coverage of FPI. Results: The coverage rates of FPI were 80.6%, with a CI value of 0.12028 for the 2014 survey, while the coverage rates of FPI were 85.2%, with a CI value of 0.10129 for the 2017 survey. The results of decomposition analysis suggested that 68.2% and 67.1% of the socioeconomic inequality in the coverage of FPI could be explained by the mother's education level for the 2014 and 2017 survey, respectively. Other risk factors including birth order, ethnic group, mother's age, maternal employment status, residence, immigration status, GDP per-capita, and the percentage of the total health spending allocated to public health could also explain this inequality. Conclusion: The socioeconomic inequity in the coverage of FPI still remained, although this gap was reduced between 2014 and 2017. Policy recommendations for health interventions on reducing the inequality in the coverage of FPI should be focused on eliminating poverty and women's illiteracy.

BACKGROUND: To evaluate the effects of a wide range of individual- and community-level factors on migrant children's primary immunization. METHODS: Migrant children aged 13-24 months (born from 1 June 2013 to 31 May 2014) were surveyed in Yiwu city, in June 2015. Social-demographic factors and vaccination records were collected. Five factors at community-level including community wealth, distance to the nearest immunization clinic, maternal education, antenatal clinic (ANC) visits, and hospital delivery were constructed. The relationship between individual- and community-level factors and a child's vaccination status for Chinese primary immunization were evaluated by logistic regression model and the adjusted odds ratio (AOR) with the p-values and 95% confidence interval (CI) were calculated. RESULTS: The community wealth (aOR:1.4; 95% CI:1.1-2.7), the community maternal education (aOR:1.8; 95% CI:1.4-4.5), the community ANC visits (aOR:1.8; 95% CI:1.3-2.8), and the community hospital delivery (aOR:2.2; 95% CI:1.6-4.8) were positively associated with the completeness of primary immunization, while community distance to the nearest immunization clinic was negatively associated with the completeness of primary immunization (aOR:0.7; 95% CI:0.5-0.9). The coverage of completeness of primary immunization was higher among children living in rural areas than those living in urban areas (aOR:1.7; 95% CI: 1.3-3.1). CONCLUSIONS: In order to achieve better vaccination coverage among migrant children in Yiwu, as well as to close the gaps and disparities of acceptability and accessibility in childhood vaccination in urban areas, policy makers should design interventions based on the factors addressed in this study.

Persistent organic pollutants such as polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs) consisting of non-ortho and mono-ortho PCBs are suggested to be very hazardous and have adverse effects on human health. However, their levels and congener profiles in retail foods marketed in Guangdong Province of China have not been elucidated thus far. Thus, in this study, 226 individual samples of beef, freshwater fish, and pork marketed across four regions of Guangdong Province were randomly collected during 2013-2015 to determine their levels of PCDD/Fs and DL-PCBs. The results showed that the total toxic equivalency quantities (TEQs) of most samples were below the maximum limits except for the 26 samples collected from the vicinities of pollution areas. The median total TEQs of these three categories were 0.174, 0.488, and 0.113pgTEQ/g fw, respectively, which indicated that the contamination status of the studied foods was not serious. For congener profiles, significantly different patterns were observed in three food groups, but with the same major TEQ contributors being 2,3,4,7,8-PeCDF in beef, freshwater fish, and pork. Regional differences of congener profiles in each food group were also found in this study, which might be attributed to the regionally different distributions of PCDD/Fs and DL-PCBs in environment media. The dietary exposures of four population subgroups (girls, boys, male adults, and female adults) to PCDD/Fs and DL-PCBs via three food groups were estimated to assessed the potential risks. They were all lower than the provisional tolerable monthly intake (PTMI, 70pgTEQ/kgbw/month) established by Joint FAO/WHO Expert Committee on Food Additive. In these food categories, the exposure to PCDD/Fs and DL-PCBs via freshwater fish was the highest one, which accounted for about 20% of PTMI, indicating that it was the major route to expose dioxin compounds.

OBJECTIVES: This study aimed to evaluate the potential achievable coverage of the second dose of measles containing vaccine (MCV2) when the protocol of simultaneous administration of childhood vaccines was fully implemented. Risk factors for missed opportunity (MO) for simultaneous administration of MCV2 were also investigated. METHODS: Children born from 1 January 2005 to 31 December 2014 and registered in Zhejiang provincial immunization information system were enrolled in this study. The MO of simultaneous administration of MCV2, the actual age-appropriate coverage (AAC) of MCV2 and the potentially achievable coverage (PAC) of MCV2 were evaluated and compared across different birth cohorts, by different socio-demographic variables. For the 2014 birth cohort, logistic regression model was used to detect the risk factors of MOs, from both socio-demographic and vaccination service providing aspects. RESULTS: Compared to the AAC, the PAC of MCV2 increased significantly from 2005 birth cohort to 2014 birth cohort (p<0.001), with a median of 12.7 percentage points. Higher birth order of children, resident children, higher maternal education background, higher socio-economic development level of resident areas, less frequent vaccination service, and shorter vaccination service time were significant risk factors of MO for simultaneous administration of MCV2, with all p-value < 0.05. CONCLUSION: The findings in this study suggest that fully utilization of all opportunities for simultaneous administration of all age-eligible vaccine doses at the same vaccination visit is critical for achieving the coverage target of 95% for MCV2. Future interventions focusing on the group with risk factors observed could substantially eliminate MOs for simultaneous administration of MCV2, further to improve the coverage of fully immunization of MCV, and finally achieve the goal of eliminating measles.

There has been a lack of socioeconomic status (SES) disparity analysis on women in China with only one child, the family planning target population. In 2008, the National Research Institute for Family Planning of China conducted a study investigating the relationship between SES and fertility intentions among 17,093 women in China who already had one child. A questionnaire was used to collect information on SES and fertility intentions, and logistic regression models were used to estimate the odds ratios and 95% CIs of fertility intentions according to SES. Compared with female farmers, women in other occupations intended to have fewer children (p < 0.05). Additionally, compared with women with low educational level (illiterate/primary), women with secondary and postsecondary education intended to have fewer children (p < 0.05) (OR = 0.70; 95% CI: 0.61-0.81 and OR = 0.56; 95% CI 0.47-0.66). A mother's education level was significantly and negatively associated with fertility intentions after adjustment for potential confounders (p < 0.05). Among Chinese women who had one child, the women with higher SES (e.g. higher educational level) had lower fertility intentions. There is an SES disparity in the fertility intention among Chinese women who already have one child. China's policy-makers should consider increasing high SES women's fertility intention.

BACKGROUND: Virtual-reality (VR) based simulation techniques offer an efficient and low cost alternative to conventional surgery training. This article describes a VR training and assessment system in laparoscopic rectum surgery. METHODS: To give a realistic visual performance of interaction between membrane tissue and surgery tools, a generalized cylinder based collision detection and a multi-layer mass-spring model are presented. A dynamic assessment model is also designed for hierarchy training evaluation. RESULTS: With this simulator, trainees can operate on the virtual rectum with both visual and haptic sensation feedback simultaneously. The system also offers surgeons instructions in real time when improper manipulation happens. The simulator has been tested and evaluated by ten subjects. CONCLUSIONS: This prototype system has been verified by colorectal surgeons through a pilot study. They believe the visual performance and the tactile feedback are realistic. It exhibits the potential to effectively improve the surgical skills of trainee surgeons and significantly shorten their learning curve.

BACKGROUND: The prevalence of obesity has been increasing over the past years in China. Bariatric surgery is an effective treatment that has been gradually accepted by obese patients. This study explored the effect of different factors on the acceptance levels of bariatric surgery. METHODS: A total of 186 obese patients (body mass index [BMI] ≥ 32 kg/m(2)) answered a questionnaire, including questions about their marital status, income level, education level, health insurance, and obesity-associated co-morbidities; 84 of these patients underwent bariatric surgery. The data was analyzed using the χ(2) test. RESULTS: Univariate analyses found that age, BMI, gluttonous behavior, income level, health insurance, medications, and weight loss expectations were correlated with the acceptance of bariatric surgery. Multivariate analyses found that BMI (P = .034) and weight loss expectations (P = .001) were positively correlated with the acceptance of bariatric surgery. Patients with gluttonous behavior accepted bariatric surgery (P = .003). However, income levels (P<.001) and health insurance (P = .001) were negatively correlated with the acceptance of bariatric surgery. CONCLUSION: Obesity was more prevalent in families of low social status and income levels; this group requires medical assistance, and education is still necessary for obese individuals of high social status and income levels.

BACKGROUND: Central venous pressure (CVP) and intrathoracic blood volume index (ITBVI) were used to assess the fluid status. It has previously been shown that CVP is not as accurate as ITBVI for all the shock patients. We therefore hypothesized that the change of CVP has the ability to predict fluid responsiveness in some clinical cases of shock. METHODS: From September 1st 2009 to September 1st 2011, sixty-three patients with shock from different Intensive Care Unit (ICU) were collected into this retrospective study. All the patients received fluid challenge strategy (infusing 300 ml hydroxyethyl starch in 20 minutes), were monitored with CVP and pulse-indicated continuous cardiac output (PICCO). The correlation between changes in cardiac index (ΔCI), CVP (ΔCVP) and ITBVI (ΔITBVI) were analyzed. Fluid responsiveness was defined as an increase in CI ≥ 10%. Receiver operating characteristic (ROC) curves were generated for ΔCVP and ΔITBVI. RESULTS: For all the patients, there was no correlation between ΔCI and ΔCVP (P = 0.073), but in the subgroup analysis, the correlation between ΔCI and ΔCVP was significant in those younger than 60 years old (P = 0.018) and those with hypovolemic shock (P = 0.001). The difference of areas under the ROC curves of ΔCVP and ΔITBVI were not statistically significant in the group younger than 60 years old or hypovolemic shock group (P > 0.05, respectively). However, no similar results can be found in the group older than 60 years old and the other two shock type groups from ROC curves of ΔCVP and ΔITBVI. CONCLUSIONS: ΔCVP is not suitable for evaluating the volume status of the shock patients with fluid resuscitation regardless of their condition. However, in some ways, ΔCVP have the ability to predict fluid responsiveness in the younger shock patients or in the hypovolemic shock patients.
