Burnout and well-being in young doctors in Hong Kong: a territory-wide cross-sectional survey.

INTRODUCTION: This territory-wide study evaluated the level of burnout and health status among young doctors in Hong Kong. METHODS: All young doctors in Hong Kong, defined as residents-in-training or doctors within 10 years of their specialist registration, were invited to participate in an online cross-sectional survey. This survey used standardised questionnaires including the Copenhagen Burnout Inventory (CBI) for burnout, Patient Health Questionnaire-9 for depression, and general health questionnaires. RESULTS: In total, 514 doctors completed the survey; 284 were doctors within 10 years of their specialist registration, while 230 were residents-in-training. There were 277 women (54%); among all respondents, the mean age was 33.7 ± 6.1 years. Using a CBI subscale cut-off score of ≥50 (moderate and higher), 72.6% (n=373) of respondents reported personal burnout; 70.6% (n=363) of respondents reported work-related burnout; and 55.4% (n=285) of respondents reported client-related burnout. Furthermore, 24% (n=125) of respondents were "somewhat dissatisfied" with their present job position; 4% (n=19) of respondents were "very dissatisfied" with their present job position. The prevalence of depression among respondents was 21% (n=110). CONCLUSIONS: In this territory-wide cross-sectional survey of young doctors in Hong Kong, a high prevalence of burnout was identified among young doctors; respondents exhibited a considerable level of depression and substantial dissatisfaction with their current positions. Strategies to address these problems must be formulated to ensure the future well-being of the medical and dental workforce in Hong Kong.

Combined aspiration thrombectomy and continuous intrasinus thrombolysis for cerebral venous sinus thrombosis: technical note and case series.

Cerebral venous sinus thrombosis is an uncommon cause of stroke with high morbidity and mortality rates from venous infarction, intracranial hemorrhage, and extensive cerebral edema. Endovascular treatment with various devices has been proposed as a salvage treatment when standard medical treatment with systemic anticoagulation is ineffective, especially in long segment dural sinus thrombosis. We describe our technique of transvenous endovascular aspiration thrombectomy with large bore thrombectomy catheters, followed by placement of microcatheter for local thrombolytic infusion at the site of thrombosis. We report a retrospective study of angiographic and clinical outcome of six consecutive patients treated with this approach. Endovascular aspiration thrombectomy with large bore catheters followed by continuous local thrombolytic infusion appeared to be a safe and effective salvage treatment for selected patients with cerebral dural venous sinus thrombosis refractory to medical treatment.

Refining the continuous tracking paradigm to investigate implicit motor learning.

In two experiments we investigated factors that undermine conclusions about implicit motor learning in the continuous tracking paradigm. In Experiment 1, we constructed a practice phase in which all three segments of the waveform pattern were random, in order to examine whether tracking performance decreased as a consequence of time spent on task. Tracking error was lower in the first segment than in the middle segment and lower in the middle segment than in the final segment, indicating that tracking performance decreased as a function of increasing time-on-task. In Experiment 2, the waveform pattern presented in the middle segment was identical in each trial of practice. In a retention test, tracking performance on the repeated segment was superior to tracking performance on the random segments of the waveform. Furthermore, substitution of the repeated pattern with a random pattern (in a transfer test) resulted in a significantly increased tracking error. These findings imply that characteristics of the repeated pattern were learned. Crucially, tests of pattern recognition implied that participants were not explicitly aware of the presence of a recurring segment of waveform. Recommendations for refining the continuous tracking paradigm for implicit learning research are proposed.

Factors affecting implementation of accreditation programmes and the impact of the accreditation process on quality improvement in hospitals: a SWOT analysis.

OBJECTIVES: The objectives of this review were to identify factors that influence implementation of hospital accreditation programmes and to assess the impact of the accreditation process on quality improvement in public hospitals. DATA SOURCES: Two electronic databases, Medline (OvidSP) and PubMed, were systematically searched. STUDY SELECTION: "Public hospital", "hospital accreditation", and "quality improvement" were used as the search terms. A total of 348 citations were initially identified. After critical appraisal and study selection, 26 articles were included in the review. DATA EXTRACTION: The data were extracted and analysed using a SWOT (strengths, weaknesses, opportunities, threats) analysis. DATA SYNTHESIS: Increased staff engagement and communication, multidisciplinary team building, positive changes in organisational culture, and enhanced leadership and staff awareness of continuous quality improvement were identified as strengths. Weaknesses included organisational resistance to change, increased staff workload, lack of awareness about continuous quality improvement, insufficient staff training and support for continuous quality improvement, lack of applicable accreditation standards for local use, and lack of performance outcome measures. Opportunities included identification of improvement areas, enhanced patient safety, additional funding, public recognition, and market advantage. Threats included opportunistic behaviours, funding cuts, lack of incentives for participation, and a regulatory approach to mandatory participation. CONCLUSIONS: By relating the findings to the operational issues of accreditation, this review discussed the implications for successful implementation and how accreditation may drive quality improvement. These findings have implications for various stakeholders (government, the public, patients and health care providers), when it comes to embarking on accreditation exercises.

Pipeline embolization device for intracranial aneurysm: a systematic review.

INTRODUCTION: The pipeline embolization device (PED) is a new endovascular stent designed for the treatment of challenging intracranial aneurysms (IAs). Its use has been extended to nonruptured and ruptured IAs of a variety of configurations and etiologies in both the anterior and posterior circulations. METHODS: We conducted a systematic review of ten eligible reports on its clinical efficacy and safety. RESULTS: There were 414 patients with 448 IAs. The majority of the IAs were large (40.2 %), saccular or blister-like (78.3 %), and were located mostly in the anterior circulation (83.5 %). The regimens of antiplatelet therapy varied greatly between and within studies. The mean number of the PED used was 2.0 per IA. Deployment was successful in around 95 % of procedures. Aneurysm obliteration was achieved in 82.9 % of IAs at 6-month. The overall incidences of periprocedural intracranial vascular complication rate and mortality rate were 6.3 and 1.5 %, respectively. CONCLUSION: The PED is a safe and effective treatment for nonruptured IAs. Its use in the context of acute subarachnoid hemorrhage (SAH) should be cautioned. Its main limitations include the need for prolonged antiplatelet therapy, as well as the potential risks of IA rupture and non-IA-related intracerebral hemorrhages (ICH). Future studies should aim at identifying factors that predispose to incomplete obliteration, delayed rupture, and thromboembolic complications.

Using bevacizumab in the fight against malignant glioma: first results in Asian patients.

OBJECTIVES: To investigate the efficacy and safety profile of bevacizumab in combination with irinotecan in Hong Kong Chinese patients with recurrent malignant glioma and to determine whether their response differed from that reported in other populations. DESIGN: Retrospective study. SETTING: Two private clinics and a public hospital in Hong Kong. PATIENTS: Fourteen individuals who presented with recurrent glioma presenting to the hospital between November 2005 and November 2009. INTERVENTION: Salvage therapy with bevacizumab (10 mg/kg) and irinotecan (125 mg/m(2) [340 mg/m(2) for those taking enzyme-inducing antiepileptic drugs]) on a 14-day schedule. RESULTS: A radiological response was observed in 12 (86%) of the patients, four (33%) of whom had a complete response. The median progression-free survival was 6 (range, 1-15) months; 71% remained progression-free at 6 months. The median overall survival was 18 (range, 9-61) months. The most common adverse events during the bevacizumab and irinotecan treatment period were haematological; five patients had grade 2/3 adverse events. Pulmonary embolism occurred in two patients, one of whom died. Intracranial haemorrhage was not detected in any of the 14 treated patients. CONCLUSIONS: Bevacizumab plus irinotecan was at least as effective at treating Chinese patients with recurrent glioma as previously reported in clinical trials in different patient populations.

Patient safety in the undergraduate curriculum: medical students' perception.

OBJECTIVE: Patient safety has emerged as a distinct health care discipline and an undergraduate programme on patient safety is being introduced at the authors' institution. The present study aimed to assess medical students' perceptions and knowledge on patient safety issues. DESIGN: A self-administered voluntary questionnaire survey. SETTING: Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong. PARTICIPANTS: A total of 130 fourth-year medical students. MAIN OUTCOME MEASURES: Students' baseline perceptions and knowledge on patient safety issues. RESULTS: The majority of students agreed that medical errors were inevitable but over 25% opined that "competent physicians do not make errors". The majority disapproved the practice of non-disclosure of error; whilst 6% would not address 'near-miss' events, and almost 10% did not support an active reporting system. Nearly half of the students were neutral on the notion that uncertainty should not be tolerated in patient care, and over 80% agreed that the most effective strategy to prevent error was "to work harder and be more careful". A knowledge gap in patient safety issues existed. Over 80% of students supported the introduction of our new undergraduate programme. CONCLUSION: Medical students were aware of medical errors being an inevitable barrier between intended 'best care' and what was actually provided to patients. Students appeared to lack the appreciation of non-physician-based causes of errors, and the importance of a multidisciplinary approach to the management of incidents. A formal curriculum on patient safety is urgently needed in this locality, and such an initiative was supported by the medical students who were surveyed.

Knowledge and attitudes toward brain stem death among university undergraduates.

BACKGROUND: Withdrawal of life support and organ procurement for transplantation are the main implications of a diagnosis of brain stem death (BSD). Various factors may impact this important decision-making process. The present study sought to investigate the knowledge and attitudes about BSD among university undergraduates as a "well-informed" subgroup of our local population. METHODS: A cross-sectional questionnaire survey was administered to a sample of nonmedical university undergraduate students in Hong Kong. RESULTS: The subjects' overall knowledge of BSD was unsatisfactory. Only 24% of subjects knew that BSD was the equivalent of legal death in Hong Kong. Among subjects who agreed to withdraw life support treatment from themselves upon the diagnosis of BSD, 30% and 24% refused to do so for their family members or a stranger, respectively. Subjects who agreed to withdraw life support showed significantly better knowledge about BSD than did those who did not agree. Concerns about doctors' inclination to diagnose BSD to save resources and extract organs for transplantation were not observed to negatively affect subjects' decisions about life support withdrawal. CONCLUSION: The level of knowledge is an important factor affecting an individual's decision concerning withdrawal of life support therapy upon the diagnosis of BSD. Adequate explanation and counseling are important to facilitate family members in coping with this important end-of-life issue.

Extended subcutaneous tunnelling technique for external ventricular drainage.

Infection is a serious complication of external ventricular drain (EVD) and various strategies have been adopted to minimize its occurrence. The use of an extended subcutaneous tunnel (50-60 cm) was previously described, but has since received little attention in the literature. The authors reviewed their experience with this technique, with emphasis on the rate of infection and predisposing risk factors. This is a retrospective review of 114 patients who received EVD with extended subcutaneous tunnel ('long EVD'). Fourteen of the 114 patients underwent more than one insertion, and a total of 133 cases of 'long EVD' were included. The mean duration of drainage was 20 days. One-hundred-and-three cases started without pre-existent infection and seven became infected, yielding an overall infection rate of 6.8%. The majority of infections were found within the first 5 days and in the third week of drainage. There was, however, no statistically significant difference in daily infection risks between the first, second and third weeks. Only intraventricular instillation of urokinase was identified as a statistically significant risk factor. Non-infective complications occurred in 17 cases (12.8%). In the present study, the overall infection rate of the 'long EVD' was comparable with that of conventional EVD, as reported by other authorities in the literature. The extended subcutaneous tunnel technique did not affect the daily infection risk on a week-to-week basis. The 'long EVD' does not appear to offer any distinct advantage over the standard tunnelling technique in our unit. However, this is essentially an audit within a single centre, and the findings should be interpreted with caution and with the understanding that individual institutions may have their unique patterns and risks of EVD infection.
