Objective:
To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients.
Methods:
Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model.
Results:
A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects.
Conclusion
The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.

Objective To compare the efficacy of insulin aspart and human soluble insulin on postprandial glucose control and blood glucose excursion in type 2 diabetic patients managed with insulin pump therapy. Methods All of 345 hospitalized type 2 diabetic patients were randomized divided into two groups. One group underwent insulin pump therapy with insulin aspart (aspart group, 173 cases),another group with human soluble insulin (humulin R group, 172 cases). Capillary glucose concentrations were measured at 9 time points,including preprandial,2 hours postprandial,bedtime (22:00),midnight(0:00) and 3:00 every day during the treatment. The change of blood glucose at each time point and the variation of postprandial blood glucose excursion was compared between the two groups. The frequency of hypoglycemia was also evaluated. Results After treatment, fasting blood glucose and post breakfast and post dinner blood glucose levels were decreased more significantly in the aspart group than those in the humulin R group. And a significantly smaller postprandial blood glucose excursion was shown in the aspart group compared with that in the humulin R group (P< 0.05). The time to achieve good glycemic control in the aspart group was (4.40 ± 2.16) d, significantly shorter than that in the humulin R group[(5.68 ± 2.29) d](P< 0.05). The incidence of hypoglycemia was significantly lower in the aspart group (P <0.05). Conclusion Insulin aspart results in better control of blood glucose and less glycemic variability compare with human soluble insulin in type 2 diabetic patients during delivery by continuous subcutaneous insulin infusion.
