This study summarizes the clinical achievement in key technologies of cancer supportive care. 1) Conceptual change. Medical teams now recognize supportive care as the core of comprehensive treatments for cancer. Supportive care is widely implemented clinically. 2) Team composition and operation mode. The program shapes an ideal supportive care team. The ideal team shall operate as one of the three models: solo practice model, congress practice model, or integrated care model according to the actual situation. 3) Scope of work. Supportive care team provides patients with spiritual care, pharmacologic assist, exercise guidance, nutritional support, effective communication, emotional support, and rehabilitation consultation. Efforts have been made to set up demonstrative wards that are free of pain, bleeding, thrombosis, hunger, and depression nationwide. 4) Standardized pain management for cancer patients. To optimize pain management, a multidisciplinary team is formed, an outpatient follow-up system is set up, and the focus is put on cancer pain education and policy advocacy. 5) A system of nutritional diagnosis and treatment. It urges the bi-diagnosis of cancer and malnutrition for inpatients and leads the proposal of the three-level diagnosis and five-ladder therapy for malnutrition. 6) Extension and expansion of supportive care out of the hospital. The program proposes the hospital-community-home management model, an integrated model for comprehensive nutritional therapy. 7) Emphasis on the quality of life. A new quality of life assessment method for cancer patients and a survival prediction model for end-stage cancer patients are established. 8) Comprehensive nursing care. It integrates spiritual care into the care of cancer patients. A management platform for continuous care service is developed with the help of internet technology and virtual reality.

Objective:To investigate the mid-term clinical efficacy and imaging changes of Waveflex semi-rigid internal fixation system combined with posterior lumbar interbody fusion (PLIF) in the treatment of double segmental lumbar degenerative diseases.Methods:The data of 51 patients with lumbar degenerative diseases who underwent surgery from September 2014 to September 2015 were retrospectively analyzed, including 29 males and 22 females, aged 65.5±5.6 years (range 58-73 years). Preoperative intervertebral space degeneration grade by University of California at Los Angeles (UCLA) and Pfirrmann intervertebral disc degeneration grade were recorded. 23 cases of primary responsible segments were treated with decompression, fixation and fusion, and adjacent secondary responsible or degenerative segments were treated with Waveflex semi-rigid internal fixation (combined group); 28 cases of double segments were treated with decompression, fixation and fusion (fusion group). Disc height index (DHI) and intervertebral foramina height (IFH) of the semi-rigid fixation segments, DHI and IFH of the upper adjacent intervertebral space, and horizontal displacement of the upper adjacent vertebral body (HD) were measured on lateral X-ray films of lumbar spine; In the fusion group, DHI and IFH adjacent to the upper vertebral space and HD adjacent to the upper vertebral body were measured. The efficacy was evaluated by short-form McGill Pain Questionnaire (SF-MPQ) and Oswestry disability index (ODI).Results:51 cases were followed up for 5.4±0.3 years (range 5.2-6.3 years). The low back and leg pain and function in the combined group and fusion group were significantly improved compared with those before operation. SF-MPQ and ODI at 3 months, 1 year, 5 years after operation were significantly different from those before operation ( P<0.05). In the combined group, the DHI of semi-rigid internal fixation segments before operation and 3 months, 1 year, 5 years after operation were 37.8%±7.6%, 37.9%±7.4%, 36.5%±6.9% and 36.0%±7.1% respectively ( P>0.05); The IFH of semi-rigid internal fixation segments before operation and 3 months, 1 year, 5 years after operation were 21.5±2.8, 21.4±2.8, 20.4±2.7, 19.4±2.4 mm respectively ( P<0.05); The DHI of the upper segment adjacent to semi-rigid internal fixation before operation and 3 months, 1 year, 5 years after operation were 37.1%±9.3%, 36.8%±9.1%, 35.2%±9.1%, 33.9%±8.8% respectively ( P>0.05); The IFH of the upper segment adjacent to semi-rigid internal fixation before operation and 3 months, 1 year, 5 years after operation were 21.9±3.0, 21.4±3.0, 20.4±2.9, 19.5±2.7 mm, respectively ( P<0.05). The HD of upper vertebral body adjacent to semi-rigid internal fixation before operation and 3 months, 1 year, 5 years after operation were 2.2±0.7, 2.3±0.5, 2.5±0.5, 2.8±0.5 mm respectively ( P<0.05). At the last follow-up, one case of semi-rigid titanium rod fracture, one case of screw loosening at semi-rigid internal fixation segment, three cases with unsatisfied numbness relief, and 2 cases of facet joint spontaneous fusion at semi-rigid fixation segment occurred in the combined group. Conclusion:Waveflex semi-rigid internal fixation can protect the degenerative lumbar intervertebral disc, and delay the degeneration of semi-rigid internal fixation segment and adjacent upper segment after interbody fusion, but long-term follow-up and study are needed.

Objective:To construct an evaluation framework with detailed indices for demonstration units (wards) of enteral nutrition nursing, in order to improve the competence of nurses in enteral nutrition nursing and inform the specialized development of enteral nutrition demonstration units (wards).Method:On the basis of literature review and expert discussion, a preliminary draft was developed, and the Delphi expert consultation method was used to conduct two rounds of consultation with 15 clinical experts in the field of enteral nutrition nursing from 15 tertiary hospitals.Results:The effective response rates of questionnaires in two rounds of consultations were both 100%. The first round of expert consultation showed an authority coefficient of 0.90 and a coefficient of variation of 0 to 0.167, while the second round showed an authority coefficient of 0.93 and a coefficient of variation of 0 to 0.113. The Kendall harmony coefficients were 0.338 and 0.368, respectively. Finally, the evaluation framework with detailed indices for the demonstration unit (ward) of enteral nutrition nursing was formed, which consisted of 3 primary indicators, 16 secondary indicators, 54 tertiary indicators, and 62 detailed items.Conclusions:The evaluation framework we developed for the demonstration unit of enteral nutrition nursing follows the diagnosis and treatment process of enteral nutrition management for inpatients, including the triad of structure, process, and outcome. The framework is objective and practical, and can inform the daily practice of enteral nutrition nursing demonstration units (wards) and the development of enteral nutrition nursing specialties.

Objective:To understand the nutritional nursing competence in the enteral nutrition demonstration wards at this stage, so as to inform subsequent training plan.Methods:From September to October in 2023, nurses from 287 institutions involved in the enteral nutrition demonstration ward construction project were selected using convenience sampling. Questionnaires on general characteristics and self-assessment scale on nutrition nursing competence were used for online survey. The status quo and influencing factors of nutrition nursing competence in included institutions were analyzed.Results:A total of 5 409 valid questionnaires were collected, with a response rate of 62.63%. The total score of nutrition nursing competence was 74.74±16.11, with the least subtotals in the domain of nutrtion knowledge. Multiple linear regression showed that influencing factors of nutrition nursing competence includes years of working, department, registered dietitian or not, nutrition management specialist or not, completion of the curriculum in enteral nutrition demonstration ward construction project, and training/supervision arranged by their department concerning nutrtion nursing and relevant evaluation criteria ( P<0.05). Conclusions:The nutritional nursing competence of clinical nurses in the wards involved in enteral nutrition demonstration ward construction project still needs to be improved. Seniors should take into consideration the varying nutritional nursing competence among junior nurses and nurses from different departments, and strengthen the training on nutrition knowledge. It should be encouraged for nurses to actively participate in nutritionist training. Actions including enhancing nutrition specialist training, establishing the multidisciplinary collaborative nutrition care team and conducting regular supervision and assessment should be implemented in the future, to improve the nutritional nursing competence among nurses.
