ObjectiveTo explore the application of PDCA cycle in the examination of medical quality of Tibetan area hospitals. MethodsIn the October 2014, PDCA cycle theory was introduced into the examination of Tibetan hospital medical quality. We collected quality problems existing in the medical activities actively, analyzed the reason and influencing factors and made corresponding plans. Then we implemented the plans and measures strictly, surveyed the results, found out and analyzed the problems, summarized the results of the examination, and turned the unsolved problems to the next PDCA circulation. Continuous follow-up was performed until the results were satisfactory. Based on Sichuan Province Secondary Comprehensive Hospital Evaluation Standard, we analyzed the medical quality of the hospital before PDCA application (July to September 2014) and after PDCA application (October to December 2014). ResultsThe incidence of medical nursing documents writing defects decreased from 12.4% to 5.9%. Hospital infection management defect rate declined from 13.5% to 5.3% and drug safety management defect rate declined from 11.8% to 2.5%, and all the differences were statistically significant (P<0.05). ConclusionPDCA cycle in the Tibetan hospital for medical quality examination has greatly improved the medical quality of Tibetan hospitals.
ObjectiveTo investigate the effect of arthroscopic debridement combined with oral glucosamine hydrochloride tablets in the treatment of knee osteoarthritis. MethodsSixty-two patients with knee osteoarthritis treated between January 2013 and April 2015 were chosen to be our research subjects. They were randomly divided into trial group (n=31) and control group (n=31). The control group was treated with arthroscopic debridement, and the trial group was given glucosamine hydrochloride tablets for treatment, apart from arthroscopic debridement. We evaluated the clinical effects by visual analogue scale (VAS) score and Lysholm knee joint function score before, and 1 week, 4 weeks, 3 months and 6 months after surgery. ResultsOne week after surgery, the VAS score and Lysholm knee joint function score were not significantly different between the two groups (P>0.05). Four weeks, 3 months and 6 months after surgery, the VAS score of the trial group was respectively 3.08±0.91, 2.46±0.87, and 1.45±0.66, and was 5.47±1.02, 3.55±1.20, and 2.37±0.53 in the control group; the Lysholm score of the trial group was 80.55±2.24, 85.35±1.79, and 89.74±4.58, respectively, and of the control group was 72.55±4.47, 74.68±2.94, and 76.69±5.63. The VAS score and the Lysholm score of the trial group were both better than those of the control group (P<0.05). ConclusionArthroscopic debridement can alleviate the symptoms of knee osteoarthritis, and oral administration of glucosamine hydrochloride tablets after surgery has obvious effects.
ObjectiveTo explore the preventive role of maintaining constant pressure of the endotracheal catheter cuff on ventilator-associated pneumonia (VAP). MethodsFrom January to December 2015, 96 patients of type Ⅱ respiratory failure were selected as the trial group who underwent intubation and mechanical ventilation more than 48 hours in the Intensive Care Unit (ICU). We used pressure gauges to measure the endotracheal catheter cuff pressure regularly and maintained a constant pressure in addition to the application of artificial airway cluster management. We recorded the initial pressure value which was estimated by pinching with finger and set initial pressure to 30 cm H2O (1 cm H2O=0.098 kPa). We measured endotracheal catheter cuff pressure and recorded it during different intervals. We reviewed 88 patients with the same disease as the control group who only accepted artificial airway cluster management between January and December 2014. Mechanical ventilation time, VAP occurrence time, ICU admission time, the incidence of VAP were recorded and analyzed for both the two groups of patients. ResultsIn the trial group, the initial pressure of endotracheal catheter cuff which was estimated by pinching with finger showed that only 11.46% of pressure was between 25 and 30 cm H2O and 82.29% of the pressure was higher than 30 cm H2O. We collected endotracheal catheter cuff pressure values during different interval time by using pressure gauges to maintain a constant management. The ratio at the pressure between 25 and 30 cm H2O was respectively 41.32%, 43.75%, 64.20%, 76.54%, 91.13%, and 91.85%. ICU admission time, mechanical ventilation time in patients of the trial group decreased more, compared with the control group, and the differences were statistically significant (t=4.171, P<0.001; t=4.061, P<0.001). The VAP occurrence time in patients of the trial group was later than the control group (t=2.247, P<0.001). ConclusionThe endotracheal catheter cuff pressure estimated by pinching with finger has errors. We recommend using pressure gauges to detect pressure every four hours, which utilizes minimal time to maintain effective pressure. The method of artificial airway of cluster management combined with the pattern of maintaining constant endotracheal catheter cuff pressure can shorten ICU admission time, mechanical ventilation time and delay the occurrence of VAP.
