Objective:This study utilizes data from the 2021 Chinese Longitudinal Healthy Longevity and Happy Family Survey(CLHLS-HF)to examine the current status of Long-Term Care Insurance(LTCI)implementation and to identify the factors influencing whether disabled elderly individuals receive formal care services.The study aims to provide policy recommendations to enhance the effectiveness and equity of the system.Methods:In this cross-sectional study, a sample of 1 447 older participants with dependency, residing in LTCI pilot areas and meeting the inclusion criteria from the 2021 CLHLS-HF, was selected.Chi-square tests and binary logistic regression analyses were employed to explore the factors influencing the receipt of formal care by dependent older individuals.Results:Among the 1 447 participants, there were 496 males with an average age of 92 years(SD 9)and 951 females with an average age of 95 years(SD 9). Of these, 701 received formal care.The logistic regression analysis revealed that factors influencing the receipt of formal care included urban residence( OR=2.237, 95% CI: 1.675-2.987, P<0.001), residing in the eastern region( OR=2.907, 95% CI: 1.747-4.837, P<0.001), living in the western region( OR=3.132, 95% CI: 1.816-5.501, P<0.001), having no children( OR=2.478, 95% CI: 1.108-5.540, P=0.027), and the degree of disability, with severe disability being more likely to receive care compared to mild( OR=0.497, 95% CI: 0.388-0.637, P<0.001)and moderate disabilities( OR=0.589, 95% CI: 0.433-0.801, P=0.001). Conclusions:Dependent older individuals in the eastern and western regions, particularly those without children or with severe disabilities, are more likely to receive formal care through the LTCI system.However, there are substantial inequities in LTCI coverage among individuals with varying degrees of disability.To enhance the effectiveness of the LTCI system, greater efforts should be directed towards economically disadvantaged regions and older individuals with mild to moderate disabilities, thereby ensuring better protection for the disabled population.

Objective To evaluate the efficiency of nursing human resources in the nursing unit of a severe medical department in a hospital by data envelopment Analysis (DEA), to explore the reasons of inefficiency and to provide basis for improving nursing efficiency. Methods Three nursing input indicators from January 2017 to December in a certain ICU (the actual number of beds in the month department, the number of nurses in the department, the actual number of working hours in the department), and 2 indicators of output indicators (total number of hospitalized patients in this month, total number of patients admitted this month) related data were selected. Using DEA to analyze and study. Results From January 2017 to December, the overall efficiency was 0.959, and there were 3 units (accounting for 25％) in overall efficiency =1, pure technical efficiency was 0.984, 6 units of pure technical efficiency =1 (accounting for 50％), and scale efficiency was 0.974, there are 3 units of scale efficiency =1 (accounting for 25％). Conclusion There is significant difference in the level of serious nursing efficiency in our hospital, and the efficiency can be maximized through rational allocation of nursing human resources.

Objective To improve the protocols of red blood cells ( RBCs) processing devices ( automatic medical RBC centrifuge, type:BBS926).Methods RBCs separated from 400 ml of whole blood collected from healthy donors were frozen at -80℃.After thawing , the cells were processed by the washing device .Based on the original protocol ( protocol 1), a modified protocol (protocol 2) was established and used to evaluate the quality of the frozen RBCs .In the test group (protocol 2), the amount of washing buffers and the washing steps were revised to form the optimized protocol .RBCs processed with the two protocols were evaluated by different assays .Results The indexes from the standards for frozen-thawed RBCs: the amount of hemoglobin ( Hb) of RBCs from protocol 1 and protocol 2 was 37.55 ±3.58 and 42.18 ±3.35 g(P<0.05),respectively;the amount of free hemoglobin(FHb) was 0.51 ±0.08 g/L and 0.53 ±0.07 g/L (P>0.05);the residual amount of white blood cells (WBCs) was (1.90 ±0.99) ×107 and (1.92 ±1.04) ×107(P>0.05);The osmolarities were 334 ±8.03 mOsm and 327 ±9.06 mOsm(P>0.05);both the bacteria and fungi tests were negative for the RBCs processed with the two protocols .Among other indexes ,the hemolysis rate for RBCs from protocol 1 and protocol 2 was (12.44 ±8.24)%and (12.02 ±5.78)%(P>0.05), the deformation index was 21.40 ±1.41 and 21.42 ±1.45 (P>0.05), the RBC recovery was(72.02 ±3.70)%and (77.18 ±5.58)%(P<0.05),the cell apopto-sis rate was(1.12 ±0.54)%and (1.10 ±0.61)%(P>0.05),and the processing time was (79.00 ±0.71)min and (79.60 ±0.55)min (P>0.05).Conclusion The RBCs processed by the two protocols meet the national standards for frozen-thaw RBCs.Hb amounts and cell recoveries of the RBCs are enhanced by treatment with protocol 2.Protocol 2 proves to be better than protocol 1.

Objective To explore the causes of deep vein thrombosis in lower extremities (DVT). Meth-ods Retrospective analysis of 411 patients with DVT being treated in our hospital from 2004 to 2009. Results 301 (73.2%) cases were with definite causes and 110( 26.8%) cases without definite causes. 195 cases occurred follow-ing operations and 68 cases following wounds and fractures. 122 cases accompanied with medical conditions ,50 cases occurred following pregnancy or child birth,39 cases suffered from cancer, 19 cases suffered from infection of lower extremity or local lesion,67 cases had past history of DVT. Conclusions Suggest that surgery, wound and fractures, postpartum, cancer, chronic illness inducing long-term bed stay and past history of DVT might correlate with DVT.
