Status and influencing factors of returning to work 6 months after discharge from hospital with severe acute pancreatitis-a cross-sectional descriptive-analytical study in China.

Objective: To describe the return to work of patients with severe acute pancreatitis within 6 months after discharge, and to explore the influence of demographic, clinical, and psychosocial factors on their return to work. Research design: Prospective 6 months follow-up study. Setting: A third class hospital in Guizhou Province. Adult of severe acute pancreatitis(18-60years), with a job before admission, in the intensive care unit ≥ 24 h, were included. Main outcome measures: To study return to work and influencing factors one, three and six months severe acute pancreatitis patients discharge. several measurements were used, including General Health Questionnaire (Demographic, disease-related, job-related and health behavior data), Readiness for Return-To-Work Scale and the Hospital Anxiety and Depression Scale. Results: Forty-three severe acute pancreatitis patients were included in our study, with mean age 41.53 years. Twenty-nine (67.44%) patients returned to work within 6 months, and fourteen patients did not return to work. The status of Readiness for Return-To-Work Scale: fourteen severe acute pancreatitis patients who did not return to work were mainly in the precontemplation dimension and prepared for action-self-evaluative dimension both 5 cases (35.71%), and the 29 patients who had returned to work were in the Proactive maintenance stage. The study showed that the independent risk factors for returning to work in SAP patients were chronic disease (OR, 0.095; 95% CI [0.011-0.822]; p=0.008), sepsis (OR, 0.071; 95% CI [0.015-0.339]; p=0.009), low education level (OR, 2.905; 95% CI [0.969-8.710]; p<0.001), and anxiety and depression at 6 months (OR, 1.418; 95% CI [0.996-2.019]; p=0.004). Conclusions: In conclusion, the return to work of patients with severe acute pancreatitis needs to be improved. Chronic diseases, sepsis, low level of education and higher degree of anxiety and depression at 6 months were important factors leading to their failure to return to work.

[Effect of early off-bed mobility on diaphragm function in intensive care unit patients undergoing mechanical ventilation].

OBJECTIVE: To explore the improvement of diaphragm function after early off-bed mobility intervention in intensive care unit (ICU) patients undergoing mechanical ventilation. METHODS: A randomized controlled trial was conducted. A total of 147 adult patients undergoing mechanical ventilation admitted to ICU of Affiliated Hospital of Zunyi Medical University from October 2019 to March 2022 were enrolled. The patients were divided into control group and observation group by convenient sampling. Except for the different intervention programs of early mobility, other treatment and nursing of the patients in the two groups were carried out according to ICU routine. Progressive early activities were performed in the control group, while early off-bed mobility was performed in the observation group. The changes of diaphragm thickness at the end of inspiratory (DTei), diaphragm thickness at the end of expiratory (DTee) and diaphragm thickening fraction (DTF) before and 24, 48, 72 and 96 hours of intervention, and the duration of mechanical ventilation, length of ICU stay and 24-hour re-intubation rate after intervention were compared between the two groups. RESULTS: Among the 147 patients, there were 4 cases of detachment in the control group and 5 cases of detachment in the observation group. Finally, 138 patients were enrolled, 69 cases in the control group and 69 cases in the observation group. There was no significant difference in gender, age, diagnosis of ICU, sedatives, muscle strength, ventilator model, acute physiology and chronic health evaluation II (APACHE II) score and DTei, DTee, DTF before intervention between the two groups. The DTei, DTee and DTF in both groups were increased gradually with the extension of intervention time, especially in the observation group [DTei (cm) at 24, 48, 72 and 96 hours of intervention in the observation group were 0.247±0.014, 0.275±0.016, 0.300±0.013 and 0.329±0.013, while in the control group were 0.242±0.015, 0.258±0.013, 0.269±0.014, and 0.290±0.017, effect of time: F = 993.825, P = 0.000, effect of intervention: F = 82.304, P = 0.000, interaction effect between intervention and time: F = 84.457, P = 0.000; DTee (cm) of the observation group were 0.213±0.014, 0.227±0.013, 0.243±0.016, 0.264±0.010, while in the control group were 0.213±0.016, 0.218±0.013, 0.224±0.013, 0.234±0.014, effect of time: F = 385.552, P = 0.000, effect of intervention: F = 28.161, P = 0.000, interaction effect between intervention and time: F = 45.012, P = 0.000; DTF of the observation group were (15.98±4.23)%, (21.35±4.67)%, (24.09±4.44)% and (25.24±3.74)%, while in the control group were (14.17±4.66)%, (18.11±3.92)%, (20.22±4.19)% and (20.98±4.12)%, effect of time: F = 161.552, P = 0.000, effect of intervention: F = 49.224, P = 0.000, interaction effect between intervention and time: F = -4.507, P = 0.000]. The duration of mechanical ventilation and length of ICU stay in the observation group were significantly shorter than those in the control group [duration of mechanical ventilation (hours): 112.68±12.25 vs. 135.32±22.10, length of ICU stay (days): 7.84±1.78 vs. 10.23±2.43, both P < 0.01]. However, there was no significant difference in 24-hour re-intubation rate between the observation group and the control group (0% vs. 2.90%, P > 0.05). CONCLUSIONS: Both early off-bed mobility and progressive early activities can prevent diaphragm weakness in ICU patients undergoing mechanical ventilation, and the effect of early off-bed mobility is better. Early off-bed mobility can significantly shorten the duration of mechanical ventilation and length of ICU stay, and it is safe and feasible.

A Study on the Correlations of Anxiety and Depression With Self-Management Ability and Endogenous Creatinine Clearance Rate in Renal Transplant Recipients.

Objective: To explore the effects of anxiety and depression on the self-management ability and endogenous creatinine clearance rate of renal transplant patients. Method: Eighty-eight renal transplant recipients who were followed up in the outpatient clinic of the Affiliated Hospital of Zunyi Medical University were selected using convenient sampling. The self-made general data sheet, Self-Rating Anxiety Scale, Self-Rating Depression Scale, and Self-Management Scale for Kidney Transplant Recipients were used. Correlation analysis was used to find factors related to endogenous creatinine clearance, while multiple linear regression was used to identify factors influencing endogenous creatinine clearance. Patients with or without anxiety and depression were divided into groups, and the indexes of the groups were compared using the independent samples t test, rank-sum test, or chi-squared test. Results: Anxiety was present in 12.5% of patients, depression in 25%, and a moderate level of self-management in 34.1%. Only 9.1% of renal transplant recipients had endogenous creatinine clearance within the normal range, and 34.1% had a body mass index not in the normal range (25% were overweight, and 9.1% were underweight). The endogenous creatinine clearance rate was negatively correlated with age and degree of depression, and positively correlated with body mass index, treatment management score, and psychosocial management score. The main influencing factors of endogenous creatinine clearance rate were age, sex, depression, body mass index, and treatment management score. The endogenous creatinine clearance rate and psychosocial management ability were significantly higher in patients without anxiety and depression than in patients with anxiety and depression (all P < 0.05). Conclusions: Anxiety and depression showed significant negative effects on the psychosocial self-management ability and endogenous creatinine clearance rate of renal transplant recipients and thus should be given more attention.

[Effect of early off-bed mobility on delirium in mechanical ventilated patients in intensive care unit: a prospective randomized controlled study].

OBJECTIVE: To investigate the feasibility of early off-bed mobility in patients with mechanical ventilation and its effect on delirium and the duration of delirium in the intensive care unit (ICU). METHODS: Adult patients who were admitted to ICU of the Affiliated Hospital of Zunyi Medical University from January 1st to December 31st 2020 for invasive mechanical ventilation and no early activity contraindication were selected. The patients were randomly divided into two groups. The experimental group conducted early off-bed mobility, such as using the shift machine off-bed sitting and walking aids to assist standing and walking, and the off-bed mobility is based on patient tolerance. The control group was given early bed activities, including conducting the joint range activity, limb movement, bed sitting, upper limb elastic belt movement, and lower limb cycling, once a day. Each joint moved 15-20 times, a total of 30 minutes. Both groups were treated with anti-infection, mechanical ventilation, analgesia and sedation, and nutrition therapy. After intervention, confusion assessment method for the ICU (CAM-ICU) was used to assess the onset and duration of delirium, physical restraint rate and duration of physical restraint, mechanical ventilation time, and the length of ICU stay. RESULTS: After excluding patients who died or gave up treatment during the intervention period, 266 patients were included, with 133 patients in the experimental group and 133 patients in the control group. There were no significant differences in gender, age, diagnosis, degree of illness, sedative drugs between the two groups. The incidence of the delirium in intervention group was significantly lower than that in control group [26.3% (35/133) vs. 42.1% (56/133), χ2 = 7.366, P = 0.007], the duration of delirium was shorter than that in control group (hours: 11.26±4.11 vs. 17.00±3.29, t = -4.157, P = 0.000), the rate of physical restraint was lower than that in control group [19.5% (26/133) vs. 45.1% (60/133), χ2 = 19.864, P = 0.000], the duration of physical restraint was shorter than that in control group (hours: 9.71±4.07 vs. 13.55±7.40, t = -5.234, P = 0.000), the mechanical ventilation time and the length of ICU stay were shorter than those in control group [mechanical ventilation time (hours) : 106.23±42.25 vs. 133.10±41.88, t = -3.363, P = 0.001; length of ICU stay (days) : 8.35±6.21 vs. 13.25±9.98, t =-4.190, P = 0.000]. CONCLUSIONS: Early off-bed mobility can reduce physical restraint rate and the incidence of delirium, and thus can accelerate rehabilitation in critically ill patients. Early off-bed mobility is safe and effective for patients with mechanical ventilation in ICU.

[Effect of progressive early bed exercise on blood flow in lower limb of patients on mechanical ventilation in intensive care unit].

OBJECTIVE: To investigate the effect of progressive early bed physical activity on blood flow in lower limb of patients on mechanical ventilation in intensive care unit (ICU). METHODS: Adult patients with mechanical ventilation ≥ 72 hours admitted to ICU of the Affiliated Hospital of Zunyi Medical University from February 22nd to November 30th, 2016 were enrolled. The patients were randomly divided into experimental group and control group by random number table method. Patients in the two groups were given the same basic treatment, including antibiotics, analgesia and sedation, mechanical ventilation, nutritional support, and routine ICU activities such as maintaining functional position of limbs and raising of bed head. On the basis of those, the experimental group was given early bed physical activity with gradual enhancement of grades I-III according to the nerve, circulation and respiration situations, such as passive/active exercise of the bicycle, straight leg lifting exercise, etc. The exercise intensity was evaluated with target heart rate, and the exercise was performed for 15-30 minutes at a time, twice a day. The control group was given intermittent pneumatic compression (IPC), 30 minutes in each time, twice a day. Mean blood flow and blood volume were measured before and immediately, 5, 10 and 15 minutes after intervention on the 3rd day. Heart rate and blood pressure were measured at 5 minutes before intervention, during 5 minutes, and 5, 10, 15, 30 minutes after intervention on the 3rd day. RESULTS: 214 adult patients were selected, after excluding the patients who died during the intervention or gave up treatment, 160 patients were included in the data analysis, with 81 in the experimental group and 79 in the control group. The mean blood flow velocity and blood volume were increased in both groups, and the mean blood flow velocity and blood flow volume in the experimental group were significantly increased and lasted longer than those in the control group [mean blood flow velocity (mm/s) of the experimental group were 11.92±1.06, 18.19±0.17, 17.24±0.14, 15.48±0.12, 12.68±0.16, and that of the control group were 12.01±1.41, 15.65±0.18, 12.91±0.14, 12.13±0.12, 11.59±0.16, respectively, the time effect was F = 1 043.101, P = 0.000, the intervention effect was F = 151.001, P = 0.000, and the interaction effect between intervention and time was F = 224.830, P = 0.001; the blood volume (mL/min) of the experimental group were 3.39±0.96, 5.59±0.11, 5.16±0.12, 4.19±0.10. 3.35±0.09, and that of the control group were 3.28±0.82, 4.04±0.11, 3.40±0.12, 3.02±0.10, 3.00±0.10, respectively, the time effect was F = 680.405, P = 0.000, the intervention effect was F = 125.359, P = 0.000, and the interaction effect between intervention and time was F = 79.631, P = 0.012]. The heart rate and blood pressure of the two groups of patients in the course of intervention were increased first, then decreased and then slowly recovered to the change trend before intervention, but the index of the experimental group fluctuated greatly [heart rate (bpm) of the experimental group were 97.64±1.50, 113.91±1.36, 105.96±1.34, 98.52±1.48, 97.84±1.46, 97.54±1.48, and that of the control group were 97.03±1.57, 105.39±1.38, 96.76±1.35, 96.54±1.50, 97.22±1.48, 96.53±1.49, respectively, the time effect was F = 235.030, P = 0.000, the intervention effect was F = 39.473, P = 0.000, and the interaction effect between intervention and time was F = 3.494, P = 0.063; the systolic blood pressure (mmHg, 1 mmHg = 0.133 kPa) of the experimental group were 118.57±1.06, 133.05±1.01, 120.44±1.10, 117.78±1.07, 117.65±1.01, 118.14±1.00, and that of the control group were 118.10±1.08, 126.68±1.02, 118.23±1.11, 117.48±1.08, 118.04±1.03, 118.90±1.10, respectively, the time effect was F = 336.604, P = 0.000, the intervention effect was F = 26.350, P = 0.000, and the interaction effect between intervention and time was F = 0.948, P = 0.332; the diastolic blood pressure (mmHg) of the experimental group were 68.07±0.72, 72.79±0.73, 70.68±0.74, 69.30±0.72, 68.73±0.74, 67.80±0.73, and that of the control group were 68.51±0.73, 72.03±0.74, 70.05±0.75, 69.10±0.73, 68.41±0.75, 67.85±0.74, respectively, the time effect was F = 286.390, P = 0.000, the intervention effect was F = 4.812, P = 0.000, and the interactive effect between intervention and time was F = 0.055, P = 0.815]. CONCLUSIONS: The effects of progressive early bed physical activity on the mean blood flow velocity and blood volume of lower limbs in ICU patients with mechanical ventilation are better than those of IPC. Although the fluctuation of heart rate and blood pressure is large, it does not cause any harm to the patients.

Influence of physical restraint on delirium of adult patients in ICU: A nested case-control study.

AIMS AND OBJECTIVES: To investigate the impact of physical restraint on delirium of adult patients in intensive care unit. BACKGROUND: Delirium is a common clinical syndrome in intensive care unit, correlated with various adverse clinical outcomes. Physical restraint is a precipitating factor for delirium; however, the effect of physical restraint on delirium, such as duration, number and appliance is still unclear. DESIGN: A nested case-control study. METHODS: A cohort of 593 intensive care unit patients were observed for 12 months, and 447 of them who received physical restraint were included for analysis. Delirium was assessed using the Confusion Assessment Method for the intensive care unit. During hospitalisation in intensive care unit, newly-onset delirium patients (the delirium group), and nondelirium patients of similar age, same gender, and conditions of mechanical ventilation and sedative drug usage (the nondelirium group) were included as the matching criteria. Patient data were acquired by reviewing medical and nursing electronic records. RESULTS: Among the 447 patients that had been physically restrained, 178 (39.8%) developed delirium. Delirium risk in patients with restraint ≥6 days was 26.30 times higher than in those <6 days. Patients who had two and three times of restraint had a 2.38-fold and 3.62-fold higher risk of delirium than those with one time of restraint. However, the appliance, site, time to apply and remove restraint had no effect on the incidence of delirium. CONCLUSIONS: The incidence of delirium is high when patients use physical restraint. Duration and number of restraint are positively related to delirium. Restrictions on the use of restraint in intensive care unit are required to reduce the occurrence of delirium. RELEVANCE TO CLINICAL PRACTICE: To reduce delirium risk of patients in intensive care unit, nurses need to assess the risk of physical restraint and consider alternative measures, thereby to achieve the minimisation of the use of restraint.

Mechanisms of human amniotic epithelial cell transplantation in treating stage III pressure ulcer in a rat model.

The aim of the present study was to determine the function of human amniotic epithelial cell transplantation (hAECT) in promoting the healing of rats with stage III pressure ulcer (PU) and to initially investigate its possible mechanisms. A total of 96 Sprague Dawley rats were allocated at random into the model, hAECT, conventional treatment or control groups (n=24 per group). In each group, 6 rats were observed to determine the wound-healing rate. The mRNA and protein expression levels of vascular endothelial growth factor (VEGF) and tumor necrosis factor (TNF)-α in the wound tissue and serum were detected using reverse transcription-quantitative polymerase chain reaction analysis and enzyme-linked immunosorbent assay. The transplantation of hAECs significantly increased the healing rate of the stage III PUs and was accompanied by the significant upregulation of VEGF mRNA and protein expression levels and the significant downregulation of TNF-α mRNA and protein expression. Immunofluorescence staining showed that, on day 7 of transplantation, hAECs remained alive inside the skin tissues. Therefore, hAECT through subcutaneous injection appears to significantly improve the wound-healing rate of stage III PUs in rats, and this effect may be associated with the upregulation of the proangiogenic factor VEGF and the downregulation of the inflammatory cytokine TNF-α.

Influence of multiple factors on the incidence of occupational blood and body fluid exposures in health care workers in Guizhou, China: A structural equation modeling approach.

BACKGROUND: We investigated the influence of multiple factors on the incidence of occupational blood and body fluid exposures (BBFEs) in health care workers (HCWs) in Guizhou, China, using structural equation modeling (SEM). METHODS: SEM tested in general hospitals was evaluated using survey data from a sample of 1,774 HCWs from 25 hospitals in Guizhou, China, between January and April 2014. RESULTS: The incidence of occupational BBFEs in HCWs was affected by HCWs' knowledge of safe work practices, HCWs' belief in their ability to use safe work practices, HCWs' use of safe work practices, the workplace safety environment, sufficiency of the controls implemented at health care facilities, and workloads. Knowledge of safe work practices had the most influence on the incidence of occupational BBFE in doctors and laboratory technicians. Ability to use safe work practices had the most influence on the incidence of occupational BBFEs in nurses. CONCLUSION: The workplace safety environment, sufficiency of controls implemented at health care facilities, HCWs' knowledge of safe work practices, HCWs' belief in their ability to use safe work practices, HCWs' use of safe work practices, and workload influence the incidence of occupational BBFEs in HCWs.

Pathologic changes of wound tissue in rats with stage III pressure ulcers treated by transplantation of human amniotic epithelial cells.

This study aims to determine the impact of orthotopic transplantation of human amniotic epithelial cells (hAECs) on the pathologic changes of wound tissues in a self-prepared rat stage III pressure ulcer model. Ninety-six SD rats were randomly divided into the model group (group M), hAEC transplantation group (group H), traditional treatment group (group T), and the control group (group C), with 24 rats in each group. The wound healing time was observed in 6 rats from each group, and 6 rats of each group were selected for post-modeling on day(s) (D) 1, 3, and 7 for HE staining to compare the pathological changes. The healing time of group H was significantly shorter than the other three groups. Moreover, pathological observations revealed that group H exhibited significant proliferation of fibrous tissues and vessels in the dermal layer, and the appearance time and degree of skin appendages were significantly greater than that observed in the other three groups. Pathological observations showed that hAEC transplantation could significantly speed up the healing of stage III pressure ulcer.

Influencing factors on use of standard precautions against occupational exposures to blood and body fluids among nurses in China.

AIMS: To investigate how specific factors, including knowledge, attitude, use of protective devices, safety climate, workload, and nurses' behaviors can influence standard precautions in China through structural equation modeling techniques. BACKGROUND: Although a number of empirical studies have been conducted, an investigation of how multiple variables influence behaviors of standard precautions among the nurses is still needed. METHODS: The study was conducted by selecting registered nurses from 25 public hospitals that operate approximately 500 beds located in different areas of Guizhou Province in China. An anonymous, self-administered questionnaire was distributed to 1000 nurses, and 964 (96.4%) completed questionnaires were returned. exploratory factor analysis was employed to examine associations of attitudes, protective devices, safety climate, workload, and nurses' behaviors with standard precautions. The identified factors were integrated in the proposed structural equation model. FINDINGS: Protective devices had a positive and major influence on nurses' use of standard precautions. Knowledge had a positive impact on the use of standard precautions through attitude mediation, and the safety climate had a positive impact on the use of standard precautions. In contrast, increasing workload had a negative effect on the use of standard precautions. The factors affecting the use of standard precautions among nurses in order of decreasing effect size were: protective devices, knowledge, attitude, safety climate, and workload. CONCLUSIONS: This study offer valuable information for healthcare management regarding the use of standard precautions to reduce occupational exposure among nurses.
