The number of students pursuing graduate qualifications has increased, especially in Asian countries and cities, such as China, Macao and Hong Kong. This paper examines the intent to pursue further studies among Chinese students according to the theory of planned behaviour. Based on responses from 321 final-year students in higher education institutions in Macao, Hong Kong and mainland China, path analysis shows that subjective norm, perceived behavioural control and attitude toward graduate studies owing to intrinsic motivation significantly affects the intent to pursue further studies. The paper also identifies the important attributes that influence students' choice of a graduate programme. These findings can help higher education management improve the effectiveness of graduate recruitment and address the concerns of Chinese students.

Importance: Few studies have directly and objectively measured the individual and combined effects of multifaceted hand hygiene education programs., Objective: To evaluate the individual and combined immediate effects of an instructional video and hand scan images on handwashing quality, decontamination, and knowledge improvement., Design, Setting, and Participants: This cluster randomized clinical trial was conducted in June to July 2023 among first-year nursing students at a university in Hong Kong. The study used an intention-to-treat analysis., Intervention: Hand hygiene education sessions featuring an instructional video, hand scan images, or both., Main Outcomes and Measures: The primary outcome was the change in residue from fluorescent lotion remaining on participants' hands after handwashing before and after the intervention. The secondary outcomes included handwashing quality and knowledge of hand hygiene., Results: A total of 270 of 280 students (mean [SD] age, 19 [1] years; 182 [67.4%] female) participated in the trial (96.4% participation rate). Participants were randomized to a control group (66 participants), hand scan image group (68 participants), instructional video group (67 participants), and hand scan image with instructional video group (69 participants). All intervention groups had greater reductions in residue after the intervention compared with the control group, although none reached statistical significance (hand scan image group: 3.9 [95% CI, 2.0-5.8] percentage points; instructional video group: 4.8 [95% CI, 2.9-6.7] percentage points; hand scan image with instructional video: 3.5 [95% CI, 1.6-5.4] percentage points; control group: 3.2 [95% CI, 1.3-5.2] percentage points). The instructional video group showed a significant improvement in their handwashing performance, with a higher percentage of participants correctly performing all 7 steps compared with the control group (22.4% [95% CI, 13.1% to 31.6%] vs 1.5% [-7.9% to 10.9%]; P < .001). Hand scan images revealed that wrists, fingertips, and finger webs were the most commonly ignored areas in handwashing., Conclusions and Relevance: In this cluster randomized clinical trial of an education program for hand hygiene, a handwashing instructional video and hand scan images did not enhance the level of decontamination. The intervention group had improved handwashing techniques compared with the control group, a secondary outcome., Trial Registration: ClinicalTrials.gov Identifier: NCT05872581.

Introduction: Vaccination is a key strategy to control the coronavirus disease 2019 (COVID-19) pandemic. Safety concerns strongly influence vaccine hesitancy. Disease transmission during pregnancy could exacerbate risks of preterm birth and perinatal mortality. This study examined patterns of vaccination and transmission among pregnant and postnatal women during the fifth wave of COVID-19 in Hong Kong., Methods: The Antenatal Record System and Clinical Management System of the Hospital Authority was used to retrieve information concerning the demographic characteristics, vaccination history, COVID-19 status, and obstetric outcomes of women who were booked for delivery at Queen Mary Hospital in Hong Kong and had attended the booking antenatal visit from 1 July 2021 to 30 June 2022., Results: Among 2396 women in the cohort, 2006 (83.7%), 1843 (76.9%), and 831 (34.7%) had received the first, second, and third doses of COVID-19 vaccine, respectively. Among 1012 women who had received the second dose, 684 (67.6%) women were overdue for their third dose. There were 265 (11.1%) reported COVID-19 cases. Women aged 20 to 29 years had a low vaccination rate but the highest disease rate (19.1%). The disease rate was more than tenfold higher in women who had no (20.3%) or incomplete (18.8%) vaccination, compared with women who had complete vaccination (2.1%; P<0.001)., Conclusion: Acceptance of COVID-19 vaccination was low in pregnant women. Urgent measures are needed to promote vaccination among pregnant women before the next wave of COVID-19., Competing Interests: All authors have disclosed no conflicts of interest.

Aims: To explore nursing students' perception of peer learning during cross-cultural learning activities through student-led webinars., Design: An exploratory qualitative study., Methods: Thematic analysis of data collected from reflective journals and focus-group interviews of participating nursing students across three international universities in Australia, Hong Kong, and Sweden during autumn 2017., Results: Three themes were identified: peer learning as creation of friendship; peer learning from interactions that went beyond what was originally intended; and peer learning as empowered learning., Conclusion: Combining peer learning as an educational approach with cross-cultural and student-led webinars provided new perspectives. On-line learning across global boundaries, based on a sound educational model, creates new opportunities for internationalization without straining individual and institutional financial resources., (© 2019 John Wiley & Sons Ltd.)

Introduction: Active surveillance is one of the therapeutic options for the management of patients with low-risk prostate cancer. This study compared the performance of six different active surveillance protocols for prostate cancer in the Chinese population., Methods: Patients who underwent radical prostatectomy for prostate cancer from January 1998 to December 2012 at a university teaching hospital in Hong Kong were reviewed. Six active surveillance protocols were applied to the cohort. Statistical analyses were performed to compare the probabilities of missing unfavourable pathological outcome. The sensitivity and specificity of each protocol in identifying low-risk disease were compared., Results: During the study period, 287 patients were included in the cohort. Depending on different active surveillance protocols used, extracapsular extension, seminal vesicle invasion, pathological T3 disease, and upgrading of Gleason score were present on final pathology in 3.3%-17.1%, 0%-3.3%, 3.3%-19.1%, and 20.6%-34.5% of the patients, respectively. The University of Toronto protocol had a higher rate of extracapsular extension at 17.1% and pathological T3 disease at 19.1% on final pathology than the more stringent protocols from John Hopkins (3.3% extracapsular extension, P=0.05 and 3.3% pathological T3 disease, P=0.03) and Prostate Cancer Research International: Active Surveillance (PRIAS; 8.0% pathological T3 disease, P=0.04). The Royal Marsden protocol had a higher rate of upgrading of Gleason score at 34.5% compared with the more stringent protocol of PRIAS at 20.6% (P=0.04). The specificities in identifying localised disease and low-risk histology among different active surveillance protocols were 59%-98% and 58%-94%, respectively. The John Hopkins active surveillance protocol had the highest specificity in both selecting localised disease (98%) and low-risk histology (94%)., Conclusions: Active surveillance protocols based on prostate-specific antigen and Gleason score alone or including Gleason score of 3+4 may miss high-risk disease and should be used cautiously. The John Hopkins and PRIAS protocols are highly specific in identifying localised disease and low-risk histology.

Introduction: Patients who undergo partial nephrectomy have been shown to be at decreased risk of renal impairment compared with radical nephrectomy. We examined the oncological outcome of patients in our centre who underwent partial or radical nephrectomy for T1 renal cancer (7 cm or smaller), and compared the likelihood of developing chronic kidney disease., Methods: This historical cohort study with internal comparison was conducted in a tertiary hospital in Hong Kong. A cohort of 86 patients with solitary T1 renal cancer and a normal contralateral kidney who underwent radical (38 patients) or partial (48 patients) nephrectomy between January 2005 and December 2010 was included. The overall and cancer-free survival, change in glomerular filtration rate, and new onset of chronic kidney disease were compared between the radical and partial nephrectomy groups., Results: A total of 32 (84%) radical nephrectomy patients and 43 (90%) partial nephrectomy patients were alive by 31 December 2012. The mean follow-up was 43.5 (standard deviation, 22.4) months. There was no significant difference in overall survival (P=0.29) or cancer-free survival (P=0.29) between the two groups. Both groups enjoyed good oncological outcome with no recurrence in the partial nephrectomy group. Overall, 18 (21%) patients had pre-existing chronic kidney disease. The partial nephrectomy group had a significantly smaller median reduction in glomerular filtration rate (12.6% vs 35.4%; P<0.001), and radical nephrectomy carried a significantly higher risk of developing chronic kidney disease (hazard ratio=5.44; 95% confidence interval, 1.26-23.55; P=0.02)., Conclusions: Compared with radical nephrectomy, partial nephrectomy can prevent chronic kidney disease and still achieve an excellent oncological outcome for T1 renal tumours, in particular T1a tumours and tumours with a low R.E.N.A.L. score.

Objectives: To review the short-term outcome of endoscopic resection of superficial upper gastro-intestinal lesions in Hong Kong., Design: Historical cohort study., Setting: All Hospital Authority hospitals in Hong Kong., Patients: This was a multicentre retrospective study of all patients who underwent endoscopic resection of superficial upper gastro-intestinal lesions between January 2010 and June 2013 in all government-funded hospitals in Hong Kong., Main Outcome Measures: Indication of the procedures, peri-procedural and procedural parameters, oncological outcomes, morbidity, and mortality., Results: During the study period, 187 lesions in 168 patients were resected. Endoscopic mucosal resection was performed in 34 (18.2%) lesions and endoscopic submucosal dissection in 153 (81.8%) lesions. The mean size of the lesions was 2.6 (standard deviation, 1.8) cm. The 30-day morbidity rate was 14.4%, and perforations and severe bleeding occurred in 4.3% and 3.2% of the patients, respectively. Among patients who had dysplasia or carcinoma, R0 resection was achieved in 78% and the piecemeal resection rate was 11.8%. Lateral margin involvement was 14% and vertical margin involvement was 8%. Local recurrence occurred in 9% of patients and 15% had residual disease. The 2-year overall survival rate and disease-specific survival rate was 90.6% and 100%, respectively., Conclusion: Endoscopic mucosal resection and endoscopic submucosal dissection were introduced in low-to-moderate-volume hospitals with acceptable morbidity rates. The short-term survival was excellent. However, other oncological outcomes were higher than those observed in high-volume centres and more secondary procedures were required.

This study aimed to examine the quality of life (QOL) of patients with advanced cancer in Hong Kong. Ninety participants were recruited from the oncology ward of the study hospital. They responded to a 28-item, 8-subscale multidimensional questionnaire and a single-item scale that measured QOL in a face-to-face interview. Participation in health care decisions, food-related concerns, and existential distress were some QOL concerns that require health care professionals' attention. Walking ability predicted the level of QOL in certain QOL domains that surfaces patients' need for rehabilitation. That the QOL domain value of life was the most important domain that predicted overall QOL calls for meaning-of-life interventions for palliative care.

OBJECTIVES. To assess primary care patients for their awareness, knowledge, and attitude towards colorectal cancer and screening, to report on the uptake of faecal occult blood test screening and the results of screening, and explore predictors of screening uptake. DESIGN. Cross-sectional study. SETTING. Four primary care clinics in Hong Kong. PATIENTS. A total of 1664 patients aged 50 to 74 years attending the clinics in the period July 2006 to July 2007. MAIN OUTCOME MEASURES. Percentage of subjects who were aware that colorectal cancer is common and curable at an early stage, and who knew that faecal occult blood test or colonoscopy is useful for screening; relevant knowledge score; uptake rate of faecal occult blood testing; rate of testing positive; and factors predicting uptake. RESULTS. A total of 1645 questionnaires were collected. In all, 89% (95% confidence interval, 88-91%) were aware that colorectal cancer is common, 95% (94-96%) believed faecal occult blood test and colonoscopy are useful for screening, and 58% (56-61%) achieved a knowledge score of 50% or above. The uptake rate of the faecal occult blood test was 35%. Uptake was higher among those with a positive family history (odds ratio=1.57; 95% confidence interval, 1.08-2.27; P=0.02), those who were more aware that colorectal cancer is common (1.86; 1.29-2.69; P=0.001), and that colorectal cancer is potentially curable at an early stage (1.76; 1.32-2.36; P=0.0001). Rate of testing positive was 2.1% (95% confidence interval, 0.9-3.3%); no colorectal cancer was detected and the neoplasia detection rate (for cancers and adenomas) was 5.1 per 1000 subjects screened. CONCLUSIONS. Patients were aware that colorectal cancer is common in our community, and faecal occult blood test or colonoscopy is useful for screening. The uptake of screening was low, though relatively higher for those with a positive family history and greater awareness of the high frequency and potential for cure of colorectal cancer. Faecal occult blood test positivity rate was 2.1%, and neoplasia detection rate 5.1 per 1000 screened.

Purpose: To evaluate the prevalence and factors associated with posterior pole and peripheral retinal lesions in Chinese subjects with high myopia., Methods: Three hundred and thirty-seven asymptomatic adults with high myopia of refractive error

Objectives: To estimate the prevalence and risk factors of diabetic retinopathy in type 2 diabetic patients, and to investigate the difference in retinopathy progression in patients with normal fundi or established retinopathy at baseline and the risk factors implicated in the progression., Design: Retrospective community-based study., Setting: Ten primary care clinics in Hong Kong., Patients: Type 2 diabetic patients; subsidiary analysis included subjects with more than one screening event., Main Outcome Measures: Patient demographics, baseline prevalence, and risk factors of diabetic retinopathy; progression of retinopathy in patients with normal fundi and established retinopathy at baseline, and the associated risk factors., Results: A total of 6165 patients were recruited from January 1998 to May 2004. Primary analysis included 4423 patients with good-quality retinal photographs. The mean age of the patients was 60.36 years (standard deviation, 10.80 years; range, 28-94 years), the mean duration of diabetes was 4.71 years (standard deviation, 4.67 years; range, 0.1-40.6 years), and the mean level of glycated haemoglobin was 7.47% (standard deviation, 1.44%). The prevalence of retinopathy at baseline was 28.4%. Subsidiary analysis showed progression to sight-threatening retinopathy was more common in the group with baseline retinopathy than that without (7.9% vs 0.7%), and occurred at a faster rate (mean, 1.5 [range, 0.5-3.0] vs 2.0 [1.0-4.2] years). Logistic regression revealed that the level of glycated haemoglobin was positively associated with both the onset (P<0.001) and progression of retinopathy (P=0.03)., Conclusion: Optimal glycaemic control is important for reducing sight-threatening retinopathy. Close observation is required for patients with established retinopathy as progression occurs more rapidly.

Objective: To compare the anatomical and visual outcomes of primary idiopathic macular hole surgery using indocyanine green-assisted internal limiting membrane peeling versus no internal limiting membrane peeling., Design: Prospective randomised controlled clinical trial., Setting: University teaching hospital, Hong Kong., Patients: Fifty-one eyes of 49 Chinese patients with primary idiopathic macular hole were studied., Interventions: Patients were randomised to undergo pars plana vitrectomy with indocyanine green-assisted internal limiting membrane peeling (26 eyes) or surgery without internal limiting membrane peeling (25 eyes). Perfluorocarbon gas was used in all cases as internal tamponade., Main Outcome Measures: Primary macular hole closure rate and best-corrected visual acuity., Results: The mean follow-up duration was 12 months (range, 6-23 months). Respectively to the indocyanine green-assisted internal limiting membrane peeling group and non-internal limiting membrane peeling group, the primary anatomical closure rate was 92.3% and 32.0% (P<0.001), whereas improvement in best-corrected visual acuity was 3.7 and 1.5 lines (P=0.002). More eyes in the first group (84.6%) had improvement of 2 or more lines of best-corrected visual acuity after surgery than in the second group (32.0%) [P<0.001]. Multivariate logistic regression showed indocyanine green-assisted internal limiting membrane peeling was the only significant predictor for primary closure of the macular hole (adjusted odds ratio=30.8)., Conclusion: Indocyanine green-assisted internal limiting membrane peeling in idiopathic macular hole surgery results in significantly better anatomical and visual outcomes compared with non-internal limiting membrane peeling in Chinese patients.

Aim: To evaluate the proportion of interventions that are evidence based in the acute care unit of a regional eye hospital., Methods: A prospective clinical audit was carried out at Hong Kong Eye Hospital in July 2002 to investigate the extent to which ophthalmic practices were evidence based. The major diagnosis and intervention provided were identified through chart review. A corresponding literature search using Medline and the Cochrane Library was performed to assess the degree to which each intervention was based on current, best evidence. Each diagnosis intervention pair was accordingly analysed and graded. The level of best, current evidence supporting each intervention was graded and analysed., Results: A total of 274 consecutive consultation episodes were examined. 22 cases were excluded since no diagnosis or intervention was made during the consultation. 108 (42.9%) patient interventions were found to be based on evidence from systematic reviews, meta-analyses, or randomised controlled trials (RCT). Evidence from prospective or retrospective observational studies supported the interventions in 86 (34.1%) patients. In 58 (23.0%) cases, no evidence or opposing evidence was found regarding the intervention. The proportion of evidence based on RCT or systematic reviews was higher for surgical interventions compared with non-surgical interventions (p=0.007). The proportion of interventions based on RCT or systematic reviews was higher for specialist ophthalmologists than trainee ophthalmologists (p=0.021)., Conclusion: This study demonstrated that the majority of interventions in the ophthalmic unit were evidence based and comparable to the experience of other specialties.

Aims: To report the clinical features and outcomes of polypoidal choroidal vasculopathy (PCV) in Chinese patients with or without laser treatment., Methods: A consecutive series of 204 indocyanine green angiographies (ICGA) performed for patients with a provisional diagnosis of age related macular degeneration were reviewed retrospectively. Inclusion criteria were ICGA with angiographic features of PCV and patients of Chinese ethnic origin. Medical records were then reviewed and patients were recalled for further assessments., Results: 22 eyes of 19 patients (9.3%) were included. The mean follow up period was 27.4 months (range 4-60 months). The mean age of patients at presentation was 65.1 years (range 51-77 years). The commonest clinical feature at presentation was subretinal haemorrhage (63.6%), followed by retinal exudation (59.1%) and haemorrhagic pigment epithelial detachment (59.1%). There was a predominance of males (68.4%), unilaterality (84.2%), and macular location of polyps (63.6%). Nine eyes received laser photocoagulation. The median initial visual acuity for both the laser and non-laser groups was 6/18. Stable or improved vision was attained in 56% and 31% of laser and non-laser groups, respectively (Fisher's exact test, p=0.38). Mean loss of Snellen lines was 3.1 and 1.1 for the two groups, respectively (two sample t test, p=0.31). At the last follow up, 15 (68.2%) eyes had poor visual acuity of 6/60 or worse, mostly attributed to disciform scar or exudative maculopathy., Conclusions: There is a predominance of males, unilaterality, and macular location of polyps in Chinese patients with PCV. The overall visual prognosis is guarded regardless of treatment. There is a large amount of variation in the natural course of PCV among different ethnic groups.

The agent that causes the enterally transmitted form of non-A, non-B hepatitis has been cloned and called hepatitis E virus (HEV). We have carried out a seroepidemiological survey on the prevalence of hepatitis E in Hong Kong. In a retrospective study, serum from 394 patients with acute viral hepatitis and 355 healthy subjects was tested for antibodies to HEV (anti-HEV) with a recombinant-based enzyme immunoassay. 65 (16.5%) patients with hepatitis were positive for IgM anti-HEV and 23 (5.8%) were also positive for IgM anti-HEV. Of 18 patients diagnosed as having acute non-A, non-B, non-C hepatitis, 6 were IgM anti-HEV positive. 17 (6%) patients in whom acute hepatitis A was diagnosed were also infected with HEV. None of 70 patients with acute hepatitis B or C or exacerbation of chronic hepatitis B was IgM anti-HEV positive. 57 (16.1%) of the healthy subjects were positive for IgG anti-HEV. The prevalence of IgG anti-HEV was higher in subjects over 20 years old than in younger subjects (24% vs 4%, p < 0.0001). IgG anti-HEV was detected in 26% of subjects who were positive for IgG antibody to HAV and in 7% of those negative for that antibody (p < 0.0001). We demonstrated the validity of the recombinant-based enzyme immunoassays for the diagnosis of hepatitis E. Our results suggest that hepatitis E accounts for a third of non-A, non-B, non-C hepatitis in Hong Kong and that coinfection of hepatitis A and E can occur.
