A double-blinded, placebo-controlled, randomized study to evaluate the efficacy of perioperative dextromethorphan compared to placebo for the treatment of postoperative pain: a study protocol
Background Pain management is a critical component of comprehensive postsurgical care, as it influences patient safety and outcomes, and inadequate control has been associated with the development of chronic pain syndromes. Despite recent improvements, the management of postoperative pain following total knee arthroplasty (TKA) remains a challenge. The use of opioid-sparing, multimodal analgesic regimens has broad support, but there is a paucity of high-quality evidence regarding optimal postoperative protocols and novel approaches are needed. Dextromethorphan stands out among both well-studied and emerging pharmacological adjuncts for postoperative pain due its robust safety profile and unique pharmacology. The purpose of this study is to evaluate the efficacy of multi-dose dextromethorphan for postoperative pain control following TKA. Methods This is a single-center, multi-dose, randomized, double-blinded, placebo-controlled trial. A total of 160 participants will be randomized 1:1 to receive either 60 mg oral dextromethorphan hydrobromide preoperatively, as well as 30 mg 8 h and 16 h postoperatively, or matching placebo. Outcome data will be obtained at baseline, during the first 48 h, and the first two follow-up visits. The primary outcome measure will be total opioid consumption at 24 h postoperatively. Secondary outcomes related to pain, function, and quality of life will be evaluated using standard pain scales, the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) questionnaire, the Patient-Reported Outcomes Measurement Information System (PROMIS-29) questionnaire, and clinical anchors. Discussion This study has a number of strengths including adequate power, a randomized controlled design, and an evidence-based dosing schedule. As such, it will provide the most robust evidence to date on dextromethorphan utilization for postoperative pain control following TKA. Limitations include not obtaining serum samples for pharmacokinetic analysis and the single-center study design. Trial registration This trial has been registered on the National Institute of Health’s ClinicalTrials.gov (NCT number: NCT05278494). Registered on March 14, 2022.
COVID-19 and Health-Related Quality of Life: A Community-Based Online Survey in Hong Kong
The COVID-19 pandemic itself and related public health measurements have had substantial impacts on individual social lives and psychological and mental health, all to the detriment of health-related quality of life (HRQoL). There have been extensive studies investigating the mental health of people in different populations during the COVID-19 pandemic. However, few studies have explored the impact of COVID-19 and its association with HRQoL. To fill this research gap and provide further empirical evidence, this study examined the impact of COVID-19 on Hong Kong people and evaluated its association with HRQoL. A total of 500 participants were randomly recruited to complete an online questionnaire on their concerns related to COVID-19. This entailed responding to the World Health Organization Quality of Life-BREF instrument. Data were collected between 24 April and 3 May 2020. Independent t-tests and multiple linear regressions were used to examine the association between the impact of COVID-19 and HRQoL. Overall, 69.6% of participants were worried about contracting COVID-19, and 41.4% frequently suspected themselves of being infected. Furthermore, 29.0% were concerned by the lack of disinfectants. All of these findings were associated with poorer HRQoL in the physical and psychological health, social relationships, and environment domains. On the other hand, 47.4% of participants were concerned that they may lose their job because of the pandemic, while 39.4% were bothered by the insufficient supply of surgical masks. These two factors were associated with poorer HRQoL in the physical and psychological health and environment domains. The adverse impact of COVID-19 on individuals is multifactorial, affecting all aspects of HRQoL. In addition to enhancing anti-epidemic efforts, it is equally important to implement public health and social welfare measures, thereby diminishing the adverse impact of COVID-19 on overall well-being.
Which psychological needs profile exhibits higher engagement and favorable attitudes toward interprofessional education? A cluster analysis among health and social care Hong Kong students
Background This study aimed to investigate which basic psychological needs profile, based on different levels of autonomy, competence, and relatedness, could exhibit higher student engagement and favorable attitudes toward interprofessional education (IPE). Methods A total of 341 undergraduate and postgraduate health and social care students enrolled in an IPE simulation participated in this study. Data were analyzed using a person-centered approach using a two-step cluster analysis, multiple analysis of variance, and bootstrapped independent t-tests. The participants completed the self-report scales such as the basic psychological needs in general questionnaire, interprofessional attitudes scale, and engagement versus disaffection with learning scale. Results Two basic psychological needs profiles emerged from the cluster analysis: a high basic psychological needs profile (i.e., high autonomy, moderately high competence, and very high relatedness) and a low basic psychological needs profile (i.e., low autonomy, moderately low competence, and very low relatedness). Students with high basic psychological needs profiles ( n  = 140; 41%) had more positive attitudes about IPE and were more behaviorally and emotionally engaged in participating in IPE tasks than students with low basic psychological needs profiles ( n  = 201; 59%). Conclusions Findings suggest that health and social care students’ engagement and attitudes toward interprofessional education differed based on their basic psychological needs profiles. Health professions educators can leverage students’ basic psychological needs in designing interventions and simulation activities to promote students’ engagement and collaborative outcomes in IPE. Enhancing students’ basic psychological needs could be crucial in fostering greater behavioral and emotional engagement and positive attitudes in participating in IPE.
The mediating role of sleep quality in the association between nocturia and health-related quality of life
Background Even though the negative impacts of nocturia on sleep quality and health-related quality of life (HRQOL) have been documented in previous research, their interrelationship has been poorly studied. This study aimed to explore whether nocturia would affect sleep quality, which in turn affects HRQOL. Methods Participants aged 40 and above were randomly recruited from a Hong Kong public primary care clinic. Participants were asked to report the average number of nocturia (waking up at night to void) pisodes per night over a 1-month period. The Pittsburgh Sleep Quality Index (PSQI) and the 12-Item Short Form Health Survey version 2 (SF-12 v2) were administered. The mediation analysis was tested using multistage regression approach and bootstrap method. Results Of the 500 subjects who completed the survey, 31.2% reported symptomatic nocturia (having ≥2 nocturia episodes per night), and 60.4% experienced poor sleep quality (a PSQI global score > 5). Respondents with symptomatic nocturia had a poorer HRQOL in the domains of physical functioning (PF), role physical (RP) and social functioning (SF), general health (GH), vitality (VT) and physical component summary (PCS) of the SF-12 v2 than those without. Compared with the respondents without poor sleep quality, those with poor sleep quality had poorer HRQOL across all domains and summaries of the SF-12 v2. Mediation analysis found that sleep quality fully mediated the association between nocturia and the PF, RP and SF domains of the SF-12 v2, respectively, and partially mediated the association between nocturia and the GH, VT and PCS domains of the SF-12 v2, respectively. Conclusions We found that sleep quality mediated the association between nocturia and HRQOL. To enhance the HRQOL of patients with nocturia, clinicians should not only focus on nocturia symptoms, but also on their sleep quality.
Attitude, Acceptability and Knowledge of HPV Vaccination among Local University Students in Hong Kong
The Human Papillomavirus (HPV) vaccine has the great potential to prevent HPV-related infections for millions of women and men worldwide. However, the success of the vaccine is highly dependent on the vaccination rate. Factors influencing the attitudes of undergraduate students towards HPV vaccination should be studied. This is a cross-sectional survey that was conducted to estimate the HPV vaccination rate among undergraduate students in Hong Kong, and to identify the predictors of their attitude towards HPV vaccination. The results showed that the HPV vaccination rate was 13.3%. Factors related to knowledge of vaccination were the main predictors of the students’ attitude towards vaccination (there were seven predictors, with B = 1.36 to 2.30; p < 0.05), followed by gender (B = −1.40; p < 0.05), acceptable maximum price (B = 0.35; p < 0.05), and willingness to receive the HPV vaccine if it can protect against cervical/anal cancer and genital warts (B = −1.90; p < 0.001). The regression model that was developed based on the predictors had a moderate effect size (adj-R2 = 0.33). To conclude, the HPV vaccination rate among undergraduate students in Hong Kong was low. They should be provided with more active education and activities to promote HPV vaccination to improve their knowledge on the subject.
Genome-Wide Association Study in Asian Populations Identifies Variants in ETS1 and WDFY4 Associated with Systemic Lupus Erythematosus
Systemic lupus erythematosus is a complex and potentially fatal autoimmune disease, characterized by autoantibody production and multi-organ damage. By a genome-wide association study (320 patients and 1,500 controls) and subsequent replication altogether involving a total of 3,300 Asian SLE patients from Hong Kong, Mainland China, and Thailand, as well as 4,200 ethnically and geographically matched controls, genetic variants in ETS1 and WDFY4 were found to be associated with SLE (ETS1: rs1128334, P = 2.33x10(-11), OR = 1.29; WDFY4: rs7097397, P = 8.15x10(-12), OR = 1.30). ETS1 encodes for a transcription factor known to be involved in a wide range of immune functions, including Th17 cell development and terminal differentiation of B lymphocytes. SNP rs1128334 is located in the 3'-UTR of ETS1, and allelic expression analysis from peripheral blood mononuclear cells showed significantly lower expression level from the risk allele. WDFY4 is a conserved protein with unknown function, but is predominantly expressed in primary and secondary immune tissues, and rs7097397 in WDFY4 changes an arginine residue to glutamine (R1816Q) in this protein. Our study also confirmed association of the HLA locus, STAT4, TNFSF4, BLK, BANK1, IRF5, and TNFAIP3 with SLE in Asians. These new genetic findings may help us to gain a better understanding of the disease and the functions of the genes involved.
Knowledge and attitude regarding organ donation among medical students in Hong Kong: a cross-sectional study
ObjectivesThe rate of organ donation in Hong Kong is among the lowest in developed regions. Since medical students will play an important role in counselling patients for organ donation and identifying potential donors in the future, their knowledge, attitudes and action for organ donation are important. This study aims to understand knowledge, attitudes and actions with regard to organ donation among medical students and investigate the factors determining the knowledge and attitudes.DesignA cross-sectional study.Setting and participantsMedical students in Hong Kong were invited to complete a questionnaire. 377 medical students participated in the study.MethodsThe questionnaire assessed their attitudes, knowledge, action of organ donation, belief and perception on organ donation, and other factors. Linear regression analyses and logistic regression were performed to analyse the effect of the variables on knowledge, attitudes and action for organ donation.ResultsAlmost all medical students (99.5%) held a positive attitude towards organ donation, but only 28.1% have signed up as organ donors. Determinants of knowledge of organ donation included belief in preservation of intact body after death (β = –0.14, 95% CI = –0.24 to –0.04) and perceived confidence and competence of organ donation discussion (β = –0.12, 95% CI = –0.22 to –0.02). Predictors of organ donor registration status included knowledge of organ donation (OR=1.03, 95% CI=1.00 to 1.06), perceived convenience of organ donation registration (OR=3.75, 95% CI=1.62 to 8.71), commitment to organ donation (OR=3.81, 95% CI=2.01 to 7.21) and exposure to organ donation (OR=4.28, 95% CI=2.37 to 7.74).ConclusionsKnowledge is positively associated with organ donation action. The above determinants of organ donation could be emphasised in medical education.
The Health-Related Quality of Life of Chinese Patients on Hemodialysis and Peritoneal Dialysis
Aims Our aim was to compare health-related quality of life (HRQOL) between end-stage renal disease (ESRD) patients and the Hong Kong general population to identify how the mode of dialysis and other factors were associated with HRQOL. Methods We conducted a cross-sectional study involving 253 hemodialysis (HD) patients and 103 peritoneal dialysis (PD) patients recruited in 2014–2015. Their HRQOL was evaluated using Kidney Disease and Quality of Life-36 (KDQOL-36) sub-scale scores and the Short Form-6 Dimensions (SF-6D) health preference score. One-way analysis of variance was used to analyze the difference in mean KDQOL-36 and SF-6D scores among PD patients, HD patients, and an exact age- and sex-matched general population. Multiple linear regressions were conducted to evaluate factors associated with the KDQOL-36 and SF-6D scores. Results The physical HRQOL of ESRD patients on dialysis was worse than that of the age- and sex-matched general population (38.4 vs. 49.6), but mental HRQOL was similar (50.7 vs. 52.0). After adjusting for all baseline characteristics, male subjects was associated with higher physical component summary (PCS), SF-6D, and symptom scores. A higher level of education (secondary or tertiary) was associated with higher mental component summary (MCS), SF-6D, symptom, and effects scores. Patients who were female, younger, married, and less educated and had a history of cardiovascular disease (CVD) and did not achieve target hemoglobin and albumin levels were associated with poorer HRQOL outcomes. Conclusions HD was associated with a greater negative impact of ESRD on daily lives than was PD, which may be a consideration when deciding on the dialysis modality for first-line renal replacement therapy. To improve HRQOL among patients on maintenance dialysis, more attention should be paid to those with demographic risk factors, preventing CVD, and meeting clinical dialysis outcome targets such as hemoglobin and albumin levels.
Antibiotic stewardship in suspected neutropenic fever (ASTERIC trial): a multicentre, type 1 hybrid effectiveness-implementation, stepped-wedge, randomised controlled trial study protocol
IntroductionNeutropenic fever (NF) has a crude mortality rate of 3–18%. International guidelines recommend that all patients with NF receive ultrabroad-spectrum antibiotics (UBSAs) within 1 hour of emergency department (ED) registration. However, over 70% patients presenting to hospital with suspected NF (sNF) cannot access absolute neutrophil count (ANC) result within 1 hour, do not have NF and do not require UBSAs. In ED and hospitalised patients with sNF, we hypothesise that the ASTERIC protocol effectively and safely reduces the use of UBSAs compared with standard care alone.Methods and analysisThis pragmatic, parallel, multicentre, type 1, hybrid effectiveness-implementation, stepped-wedge, before-and-after, cluster randomised controlled trial aims to evaluate whether antibiotic prescribing can be safely reduced through implementing a multifaceted antibiotic stewardship intervention (ASTERIC) in adult patients with sNF presenting to EDs. The sNF was defined as a fever with a single oral temperature of ≥38.3°C (101°F) within 24 hours before ED registration or a temperature of ≥38.0°C (100.4°F) sustained over a 1-hour period, following last chemotherapy or targeted therapy within 6 weeks for any solid tumour, or in any period following therapies against leucaemia, lymphoma, myelodysplastic syndrome, aplastic anaemia, multiple myeloma or recipient of HSCT. The study will involve eight hospitals in Hong Kong with variable baseline practice. We will include 704 adult patients (352 patients in pre-implementation and post-implementation periods, respectively) with sNF (tympanic temperature ≥38.3°C) and 48 staff participants (6 staff participants in each hospital). Healthcare professionals will receive a multifaceted stewardship intervention consisting of risk assessment tools, fast-track ANCs, a decision tool for patient management and antibiotic use, supported by an educational package and staff interaction programmes (ASTERIC protocol). Patients’ blood ANC, and cancer therapy and chronic illness therapy scores will be measured. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) and Proctor conceptual frameworks will be followed for evaluation of implementation. The main outcome measures are the mean total dose of UBSAs prescribed in 7 days and serious adverse events at 30 days. Data analysis will incorporate intention-to-treat, per-protocol and as-treated analyses for service outcomes (effectiveness, safety, quality of life assessments and cost-effectiveness) and mixed methods for implementation outcomes, informed by the Theoretical Domains Framework. We expect that the study results will inform health policy with improvement in hospital services in treating stable sNF, evidenced by improved safe antibiotic stewardship, early antibiotic de-escalation and reduced costs and length of stay.Ethics and disseminationThe institutional review boards of all study sites approved this study. This study will establish the ASTERIC protocol safely improves antibiotic stewardship and clinical management in adult patients with sNF. We will disseminate the findings through peer-reviewed publications, conference presentations and educational activities. All patients with sNF will be influenced by the new protocol which is agreed at hospital level. Randomisation is at hospital level, not patient level. Patient consent is sought for follow-up and data access, not for treatment. Staff consent is sought for interviewing.Trial registration numberNCT06794320.
IDDF2021-ABS-0005 Nutrition support team for intestinal failure patients on parenteral nutrition: improving macro-and-micronutrients intake
BackgroundA nutrition support team (NST) is a multidisciplinary team of physicians, pharmacists, nurses and dietitians, who are responsible for managing patients with complex nutritional needs. NST improves the quality of treatment, clinical outcomes and reduces costs by avoiding unnecessary treatments and simplifying the treatments used. This study reviewed the outcomes achieved after the implementation of an NST on a group of patients who were given parenteral nutrition (PN) at a local acute hospital.MethodsA total of 81 patient records were retrieved for service evaluation analysis. Among the subjects, 44 of the patients on PN who were seen by the NST from Apr 2017 – Jun 2019 were compared to the historical control of 37 patients on PN who have not received NST or dietitian intervention during the period from Mar 2016 – Mar 2017. Energy, protein, and micro-nutrients consumption adequacy were compared between the intervention and control groups. Patients without body weight and nutrition intake records were excluded. Independent t-test and chi-square test were used to compare the variables between both groups. A p-value of <0.05 was considered statistically significant.ResultsThe patients in the intervention group had a significantly higher energy and protein intake than that of the control group (1279±353kcal versus 934±261kcal; 58±16g versus 43±12g). In terms of nutritional intake adequacy, the percentage of targeted energy and protein requirement achieved is significantly higher in the intervention group (81±21% and 90±28% of their energy and protein requirements respectively), compared to 64±21% and 75±23% in the control group. Adequacy of micronutrient consumption is also significantly higher in the intervention group, 88.6% of patients in the intervention group achieved adequate intake of micronutrients from PN compare to 8.1% of patients in the control group.ConclusionsNutrition care provided by the NST is promising to ensure the nutrition well-being of hospitalized malnourished patients. This review suggests that NST intervention can improve both macro- and micronutrient intake adequacies in patients on parenteral nutrition support. Further clinical outcomes studies on the benefits of NST are recommended.
