Spinal or general anaesthesia for surgical repair of hip fracture and subsequent risk of mortality and morbidity: a database analysis using propensity score‐matching

Around 76,000 people fracture their hip annually in the UK at a considerable personal, social and financial cost. Despite longstanding debate, the optimal mode of anaesthesia (general or spinal) remains unclear. Our aim was to assess whether there is a significant difference in mortality and morbidity between patients undergoing spinal anaesthesia compared with general anaesthesia during hip fracture surgery. A secondary analysis examined whether a difference exists in mortality for patients with pre‐existing cardiovascular disease or chronic obstructive pulmonary disease. This was a clinical database analysis of patients treated for hip fracture in Nottingham, UK between 2004 and 2015. Propensity score‐matching was used to generate matched pairs of patients, one of whom underwent each mode of anaesthesia. Data were analysed using conditional logistic regression, with 7164 patients successfully matched. There was no difference in 30‐ or 90‐day mortality in patients who had spinal rather than general anaesthesia (OR [95%CI] 0.97 [0.8–1.15]; p = 0.764 and 0.93 [0.82–1.05]; p = 0.247 respectively). Patients who had a spinal anaesthetic had a lower‐risk of blood transfusion (OR [95%CI] 0.84 [0.75–0.94]; p = 0.003) and urinary tract infection (OR [95%CI] 0.72 [0.61–0.84]; p [less than] 0.001), but were more likely to develop a chest infection (OR [95%CI] 1.23 [1.07–1.42]; p = 0.004), deep vein thrombosis (OR [95%CI] 2.18 [1.07–4.45]; p = 0.032) or pulmonary embolism (OR [95%CI] 2.23 [1.16–4.29]; p = 0.016). The mode of anaesthesia for hip fracture surgery resulted in no significant difference in mortality, but there was a significant difference in several measures of postoperative morbidity

Building of Dental Knowledge among Parents of Preschool Children

Conference Theme: We are the FuturePoster PresentationSession 10: P1Objective: To assess the education outcome of building dental knowledge among parents of preschool children in Hong Kong. Method: Ethics approval (IRB UW12-334) was achieved. Workshops (seminars, group discussion and Q&A sessions) were given by outreach dentists in 9 kindergartens to build the dental knowledge among the parents. Oral examination was carried out for the children by 2 calibrated outreach dentists before the workshops. The parents were invited to complete the same questionnaire with 47 multiple choice questions to assess their dental knowledge before the workshop and 1 month after the workshop. Correct answer for each question was given a score, and the total score could be 0 to 47. Pearson correlation was run to analyze the relationship between the caries prevalence and the pre-workshop score as well as the score change. A sample of parents who did not attend the workshops was recruited as control. Paired t-test was carried out to assess the short-term education outcome, and two-sample t-test to compare the score between the test and control groups of parents. Result: There were 314 parents who participated in this study and 157 were in control group. The pre-workshop scores were negatively related to the caries prevalence (p<0.05). The score (±SE) of dental knowledge before the workshop in the tested and control group of the parents were 26.39±0.75 and 24.55±0.75, respectively (p=0.082), while their scores after the workshops were 31.78±0.66 and 25.64±0.67, respectively (p<0.001). Paired t-test showed a significant increase of the score of the test group (p<0.001) but not the control group (p=0.132). The change of score before and after workshops was not related to the caries prevalence (p=0.374). Conclusion: In this study, short term oral health knowledge of parents of preschool children was improved by attending the dental knowledge building workshop.
