Introduction: This paper reports on research conducted within a Hong Kong (HK) accident and emergency department (AED), which investigated the effectiveness of health care worker-patient communication over the course of patients' journeys from triage to disposition. Methods: The research combined qualitative and quantitative ethnographic methods with linguistically-oriented discourse analysis of audiotaped interactions between patients and health care workers. It involved: (1) observations, (2) semi-structured interviews with management and health care workers, (3) surveys with AED staff, (4) audio-recordings of 10 patients' journeys, and (5) follow-up interviews with patients. Results: The paper described the typically complex communication networks involved in AED care. It then exemplified how certain communicative strategies, balancing the communication of medical knowledge with interpersonal communication, could be used to achieve positive healthcare outcomes. This was illustrated by a case study of one patient's journey through the AED, pinpointing health care workers' effective use of communication strategies, their effect on the patient's participation and subsequently the patient's understanding and evaluation of the care he received. Conclusion: The high stress nature of AEDs inevitably poses challenges to communication. The results of this study, however, strongly suggest a correlation between health care workers' use of effective, interpersonally sensitive communication strategies and positive patient outcomes. Health care worker-patient communication that effectively balances interpersonal communication with the communication of medical expertise is integral to ensuring patients' participation in, understanding of, and satisfaction with their healthcare. These communication strategies should be required components in health care worker communication training.

To find out the characteristics and presentations of imperforate hymen in the local population in Hong Kong and to assess if diagnosis of imperforate hymen made in the emergency department can reduce time to operation and length of hospital stay. Design: Retrospective study. Setting: A regional public hospital in Hong Kong. Patients: We retrospectively collected data of all patients with the diagnosis of imperforate hymen (ICD 9 coding 752.42) from the period of January 1999 to June 2009. Demographics of the patients, their presenting symptoms and signs, the diagnostic process, investigation findings and time of operation were recorded and analysed. Results: Fifteen cases of imperforate hymen were reported during that period. All were adolescent girls aged from 10 to 15 years. A total of 13 patients presented to the accident and emergency department (AED). Seven patients had the diagnosis made in the AED and 2 patients received bedside pelvic ultrasound. More than half of them (8 patients) presented with acute retention of urine. Other presentations included lower abdominal pain, constipation, lower abdominal mass, and protruding introital mass. Most cases diagnosed in the AED (5 out of 7) were admitted to the gynaecology ward while the others were admitted to the surgical or urology wards. Five out of the 7 cases diagnosed in the AED received operation within 24 hours; whereas only 1 out of the 6 cases with the diagnosis made after admission had operation within 24 hours. The difference was statistically significant (p=0.035, Fisher's exact test). The mean length of stay of the group diagnosed in the AED was 1.9 days while the mean length of stay for the group diagnosed after admission was 4.2 days. Conclusion: Early diagnosis of imperforate hymen and haematometrocolpos in the AED for adolescent girls with primary amenorrhoea could have positive impact on proper admission to the gynaecology ward, prompt operation and shorter length of stay in hospital.

Introduction Primary trauma diversion (PTD) enables direct transfer of major trauma patients to trauma centres for definitive care. This study aimed to evaluate the performance of PTD in the New Territories West Cluster (NTWC) of Hospital Authority and to identify the predictors for under-diversion. Methods A cross-sectional study based on local trauma registry. All major trauma patients (defined as ISS>15 or requiring trauma team activation) in the catchment area of the local hospital from September 2007 to December 2011 were included. The appropriateness of diversion decision was independently evaluated by an expert team (a trauma nurse coordinator and an emergency medicine practitioner). The sensitivity, specificity, predictive values, agreement, over-diversion and under-diversion rates were calculated. Potential predictors for under-diversion including age, Glasgow Coma Scale, mechanism of injury, injured body part, and the distance from scene to the trauma centre/local hospital were employed for logistic regression analysis. Results There were 141 eligible cases identified. The sensitivity and specificity for PTD were 59.5% and 96.5% respectively. The over-diversion rate was 3.5% and the under-diversion rate was 40.5%. The overall accuracy was around 74.5%. Non-motor vehicle accident (OR 13, 95% confidence interval [CI]=3.5-48.0, p<0.01) and isolated head injury (OR 5.35, 95% CI=1.5-19.5, p=0.01) were 2 independent predictors for under-diversion in PTD. Conclusions The overall field triage compliance by the paramedics is satisfactory. Under-diversion rate in NTWC is high. Non-motor vehicle accident mechanism and isolated head injury are 2 significant predictors for under-diversion. Reinforcement in training to avoid potential pitfalls would improve the paramedics' trauma triage performance.

The crude cost of providing IFT service by the ED was reasonable and acceptable.

Sodium hypochlorite is widely used as an irrigating solution in dental practice. Despite its safe properties, serious complications can result from inadvertent use. We report a patient presenting to the accident and emergency department for sodium hypochlorite accident during dental root canal therapy. The management of this dental emergency condition is discussed.
