Objective To explore effect of pre-programmed guidance of functional exercise on exercise compliance and accuracy of patients after lumbar surgery.Methods From January to March 2016, 60 patients who had undergone the surgery of lumbar spine internal fixation were selected as the research object. All patients were divided into intervention group and control group randomly, 30 patients in each group. Patients in the control group underwent routine postoperative functional exercises. Patients in the intervention group received preoperative functional exercise instruction before 2 days. According to the self-designed questionnaire, we evaluated the compliance and accuracy of functional exercises of the two groups by asking, checking and demonstrating.Results At first day after operation, the proficiency on ankle pump exercises and straight-leg-raising movement showed no significant difference between two groups (P>0.05); However, on supine siding leg movement to right-left, compared with the control group, the intervention group were significantly better (Z=-5.100,P<0.001). At first day after removing wound drains, the proficiency on ankle pump exercises and raising buttock with five positions showed no significant difference between two groups (P>0.05), but on straight-leg-raising movement (Z=-2.316,P=0.021) , supine siding leg movement to right-left (Z= -4.238,P<0.001), lateral siding leg movement to front-back (Z=-3.027,P=0.002) and lateral straight-leg-raising movement (Z=-3.027,P=0.002), the intervention group was significantly better than the control group. Moreover, as far as adherence of exercise, patients in the intervention group were obvious better (Z= -2.156,P=0.031).Conclusions The pre-programmed guidance of functional exercise can improve the patient's awareness and confidence of functional exercise on rehabilitation, reduce the patients' psychological anxiety, so as to improve the compliance and the correct rate of functional exercise, promote their recovery. It also can save time for propaganda, improve work efficiency.

Objective:To construct a risk prediction and assessment system for incisional infection after spinal surgery.Methods:Based on the failure mode and effect analysis (FMEA), risk factors and assessment indicators of postoperative incisional infection in spinal surgery were sorted out through literature search followed by expert consultation using the Delphi expert consultation method. After three-level assessment indicators were selected according to their importance and expert opinions and assigned by different scores, a risk prediction and evaluation system was constructed for postoperative incisional infection after spinal surgery.Results:The 2 rounds of expert consultation questionnaire resulted in an effective response rate of 100%. The degree of expert consultation authority was 0.85, showing high reliability; the Kendall coordination coefficients of expert consultation ranged from 0.525 to 0.686, showing good coordination ( P<0.05). The three-level assessment indicators consisted of 3 primary, 18 secondary and 54 tertiary ones. After statistical analyses of the important risk indicators selected which consisted of 6 preoperative evaluation ones and 18 postoperative evaluation ones, 6 preoperative and 12 postoperative predictive indicators were obtained. The values of risk priority number (RPN) were calculated for high, medium and low risks for postoperative incisional infection using a semi-quantitative method. Conclusion:A self-designed system has been constructed for risk prediction and assessment of incisional infection after spinal surgery based on expert consultation and FMEA method.
