ObjectivesTo systematically review the concept, definition, development, operation mechanism, function, efficacy, advantages and challenges of pharmacy benefit management (PBM), in order to provide evidence for its introduction and application in China.MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data and CBM databases were searched to collect literatures on researches, policies, and applications related to PBM from January 1st, 2000 to January 1st, 2017. Two researchers independently screened literatures, extracted data and used the AHRQ evaluation list to evaluate the quality of the observational studies, then qualitative method was used to review literature.ResultsA total of 12 researches were included. The results showed that PBMs had played an important role in negotiation discounts with drug manufacturers, supervising drug circulation and doctors' prescription behaviors, delivering health management services for patients, prescription payments with highly information-oriented systems, etc., which, as a result, could reduce the medication burden of patients with superior diseases management.ConclusionsChina's attempt to adopt a PBM model must take full account of practical conditions, which involves health management system, pharmaceutical market environment and social culture. It cannot merely emulate the PBM model of the United States. With consideration of local conditions, China can explore a suitable path for its own PBM model.
Objective To invest igate the operat ive method and cl inical ef f icacy of reconstruct ing metacarpophalangeal joint defect by the second toe proximal interphalangeal joint with skin flaps. Methods From March 2003 to January 2008, 26 cases (26 fingers) with metacarpophalangeal joint defect were treated, including 19 males and 7 females aged 18-36 years old (average 27 years old). Among them, 23 cases were caused by mechanical injury and the time from injury to operation was 1-6 hours; while 3 cases suffered from secondary injury due to trauma and the time from injury to operation was 3-12 months. Four thumbs, 10 index fingers, 8 middle fingers, 3 ring fingers and 1 l ittle finger were injured.The metacarpophalangeal joint defects were 2 cm × 1 cm-4 cm × 2 cm in size, and 22 cases were combined with skin and soft tissue defect (1.5 cm × 1.5 cm - 6.0 cm × 5.0 cm). During operation, the second toe proximal interphalangeal joint with skin flaps was transplanted to reconstruct those defects, 20 fingers received whole-joint transplantation and 6 fingers received halfjoint transplantation. The skin flaps ranging from 2.0 cm × 1.5 cm to 6.5 cm × 6.0 cm in size were adopted. The donor site of 21 cases received toe amputation, and the rest 5 cases received joint fusion. Results The transplanted joints and skin flaps of all the 26 fingers survived. All incisions and donor sites healed by first intention. All patients were followed up for 6-20 months (average 12 months). The union of transplanted joints was achieved in all the cases at 6-12 weeks after operation, no bone nonunion and refracture occurred. The flexion range of transplanted metacarpophalangeal joints was 30-75° (average 45°). Joint activity was evaluated according to the total active movement/total passive movement assessment criteria, 8 fingers were excellent, 13 good, 3 fair, 2 poor, and the excellent and good rate was 80.77%. The foot donor-site abil ity to walk was unaffected. Conclusion Applying second toe proximal interphalangeal joint with skin flaps is an effective approach to reconstruct the metacarpophalangeal joint defect, and the function recovery of the injured joints is satisfying.
Objective?To investigate the surgical method and clinical efficacy of repairing whole-hand destructive injury or hand degloving injury with the transplant of pedis compound free flap.?Methods?From February 2003 to June 2008, 21 patients with whole-hand destructive injury or hand degloving injury were treated, including 15 males and 6 females aged 18-45 years old (average 25 years old). The injury was caused by punching machine crush in 10 cases, roller crush in 7 cases, and imprinter crush in 4 cases. The time between injury and operation was 1-9 hours. Eleven cases had the skin-degloving injury of the whole hand, while the other 10 cases had the proximal palm injury combined with dorsal or palmar skin and soft tissue defect. After debridement, the size of wound was 9 cm × 7 cm - 15 cm × 10 cm in the dorsal aspect and 10 cm × 7 cm -16 cm × 10 cm in the palmar aspect. The defect was repaired by the thumbnail flap of dorsalis pedis flap and the second toenail flap of dorsalis pedis flap in 5 cases, the thumbnail flap of dorsalis pedis flap and the second toe with dorsalis pedis flap in 4 cases, and bilateral second toe with dorsalis pedis flap in 12 cases. The flap area harvested during operation ranged from 6 cm × 5 cm to 16 cm × 11 cm. Three fingers were constructed in 2 cases and two fingers in 19 cases. Distal interphalangeal joint toe amputation was conducted in the thumbnail flap donor site, metatarsophalangeal joint toe amputation was performed in the second toenail flap donor site, and full-thickness skin grafting was conducted in the abdomen.?Results?At 7 days after operation, the index finger in 1 case repaired by the second toenail flap suffered from necrosis and received amputation, 1 case suffered from partial necrosis of distal dorsalis pedis flap and recovered after dressing change, and the rest 42 tissue flaps survived. Forty-three out of 44 reconstructed fingers survived. All the wounds healed by first intention. At 2 weeks after operation, 2 cases had partial necrosis of the donor site flap and underwent secondary skin grafting after dressing change, the rest skin grafts survived, and all the wounds healed by first intention. Nineteen cases were followed up for 6-36 months (average 11 months). The flaps of palm and dorsum of hand showed no swelling, the reconstructed fingers had a satisfactory appearance and performed such functions as grabbing, grasping, and nipping. The sensory of the flaps and the reconstructed fingers recovered to S2-S4 grade. The donor site on the dorsum of the foot had no obvious scar contracture, without obvious influence on walking.?Conclusion?For the whole-hand destructive injury or hand degloving injury, the method of transplanting pedis compound free flap can repair the defect in the hand and reconstruct the function of the injured hand partially. It is an effective treatment method.
Objective To explore the mental health status and influencing factors of clinical medical students pursuing a professional master’s degree under the “dual-track integration” training systems. Methods Clinical medical students pursuing a professional master’s degree who underwent residency standardized training in 123 hospitals from different areas of China were selected as the research objects from May 28th to June 4th, 2024, and the mental health and stress were investigated by questionnaire. Results A total of 1195 clinical medical students pursuing a professional master’s degree were included. Symptom Checklist-90 analysis showed that 582 (48.7%) master students had mental health problems. The two-group students (with and without psychological problems) had statistical differences in exercise frequency, sleep quality, extent of staying up late, interpersonal communication, and average number of night shifts per month (P<0.001). The subjective scores of interpersonal pressure, economic pressure, love and marriage pressure, schoolwork pressure, scientific research pressure, clinical work pressure, entering higher education pressure and employment pressure, and the proportion of graduating from 985/211 university of the master students with psychological problems were significantly higher than those of the master students without psychological problems (P<0.001). Logistic regression analysis showed that poor sleep quality [odds ratio (OR)=1.626, 95% confidence interval (CI) (1.085, 2.438), P=0.019], 985/211 university degree [OR=1.448, 95%CI (1.097, 1.910), P=0.009], interpersonal pressure [OR=1.194, 95%CI (1.121, 1.272), P<0.001], love and marriage pressure [OR=1.067, 95%CI (1.014, 1.122), P=0.012] and entering higher education pressure [OR=1.110, 95%CI (1.055, 1.167), P<0.001] were independent risk factors, while the male sex [OR=0.621, 95%CI (0.472, 0.817), P=0.001] were protective factor for psychological problems of these medical students. Conclusions Under the “dual-track integration” training systems, the clinical medical students pursuing a professional master’s degree have a higher prevalence of psychological problems, especially the females and the 985/211 bachelor’s degree scholars. It is important to improve sleep quality, strengthen interpersonal interaction and reduce pressure load to improve the mental health level of these clinical medical students.
