Test-retest reliability of Common Mental Disorders Questionnaire (CMDQ) in patients with total hip replacement (THR)

Abstract Background: Among older patients worldwide, communication has become an important public health issue in the world. This communication could be improved by different interventions. However, a tool of measuring patients’ confidence in communication with doctors has not been established in China. This study is aimed at translating and introducing the Patient's Communication Self-Efficacy Scale for assessing communication between doctors and elderly patients.Method: (1) A post-consultation questionnaire was completed by 167 patients (mean age = 70.04 years; SD: 6.3 years; females/males: 94/73). The researchers translated the English version PCSS into Chinese under the guidance of the original author. (2) The final Chinese version of the PCSS was validated. Measurement indices included item generation, reliability testing, construct validity and test-retest reliability. To carry out the above tests, we used SPSS 19.0 software and LISREL 8.7. We built the Bayesian network model of the Chinese version of the PCSS and determined predictive variables.Result: Confirmatory factor analysis showed that the Chinese version of the PCSS fit a three-dimensional model. Additionally, the Chinese version of the PCSS has high internal consistency (Cronbach’s α coefficient 0.929) and test-retest reliability (Kappa coefficient 0.761). The Bayesian networks shows that the important predictors are education (0.4207), PEPPI 3 (0.3951), and PCSS 1 (0.1139). The connections between PCSS 3 and other variables do not indicate causality but rather conditional dependencies or interrelatedness.Conclusion: This is the first study to validate the Chinese version of the PCSS in outpatients after total hip replacement. Our results confirmed that the Chinese version of the scale has high internal consistency, construct validity and test-retest reliability. Patient-doctor interaction and education are important predictors of patient communication self-efficacy.

SummaryLower rates of deep vein thrombosis have been noted following total hip replacement under epidural anesthesia in patients receiving exogenous epinephrine throughout surgery. To determine whether this is due to enhanced fibrinolysis or to circulatory effects of epinephrine, 30 patients scheduled for primary total hip replacement under epidural anesthesia were randomly assigned to receive intravenous infusions of either low dose epinephrine or phenylephrine intraoperatively. All patients received lumbar epidural anesthesia with induced hypotension and were monitored with radial artery and pulmonary artery catheters.Patients receiving low dose epinephrine infusion had maintenance of heart rate and cardiac index whereas both heart rate and cardiac index declined significantly throughout surgery in patients receiving phenylephrine (p = 0.0001 and p = 0.0001, respectively). Tissue plasminogen activator (t-PA) activity increased significantly during surgery (p <0.0005) and declined below baseline postoperatively (p <0.005) in both groups. Low dose epinephrine was not associated with any additional augmentation of fibrinolytic activity perioperatively. There were no significant differences in changes in D-Dimer, t-PA antigen, α2-plasmin inhibitor-plasmin complexes or thrombin-antithrombin III complexes perioperatively between groups receiving low dose epinephrine or phenylephrine. The reduction in deep vein thrombosis rate with low dose epinephrine is more likely mediated by a circulatory mechanism than by augmentation of fibrinolysis.

SummaryTwelve patients undergoing total hip replacement, with regional anaesthesia and with dextran infusion for plasma expansion and thromboprophylaxis, were given the vasopressin analogue desmopressin (DDAVP) or placebo in a randomized, double-blind prospective study. In controls (n = 6) we found a prolongation of the bleeding time, low factor VIII (FVIII) and von Willebrand factor (vWF) and a decrease in antithrombin III to levels known to be at risk for venous thrombosis. Desmopressin shortened postoperative bleeding time, gave an early FVIII/vWF complex increase, prevented antithrombin III from falling to critically low values and appeared to activate the fibrinolytic system, both by tPA increase and PAI-1 decrease.Thus in the controls we found changes in both coagulation and fibrinolysis indicating a haemorrhagic diathesis as well as a risk for thromboembolism. Desmopressin induced factor changes that possibly reduce both risks.

SummaryThe effect of subcutaneous low-dose heparin on postoperative deep-vein thrombosis (D. V. T.) (diagnosed by the 125I-labelled fibrinogen test) has been investigated in a trial of 143 patients undergoing the operation of total hip replacement. Two randomized studies were carried out: in one the scanning for D.V.T. was carried out daily for 7 days post operatively and in the other for 15 days. In both, the incidence of D.V.T. was significantly lower in the heparin-treated patients (P<0.005). Bilateral D.V.T. was also prevented (P<0.05), through the extension of D.V.T. to the distal veins of the thigh was not significantly reduced. Heparin treatment was, however, followed by a higher incidence of severe postoperative bleeding (P< 0.02) and wound haematoma formation (P< 0.005), and the postoperative haemoglobin was significantly lower than in the control group (P<0.005). A higher number of transfused blood units was also needed by the heparin treated patients (P<0.001).
