Can ChatGPT Provide Quality Information on Integrative Oncology? A Brief Report.

This short report evaluated the accuracy and quality of information provided by ChatGPT regarding the use of complementary and integrative medicine for cancer. Using the QUality Evaluation Scoring Tool, a panel of 12 reviewers assessed ChatGPT's responses to 8 questions. The study found that ChatGPT provided moderate-quality responses that were relatively unbiased and not misleading. However, the chatbot's inability to reference specific scientific studies was a significant limitation. Patients with cancer should not rely on ChatGPT for clinical advice until further systematic validation. Future studies should examine how patients perceive ChatGPT's information and its impact on communication with health care professionals.

Provision of a personalized survivorship care plan and its impact on cancer-related health literacy among childhood cancer survivors in Hong Kong.

PURPOSE: To evaluate the short-term effectiveness of a personalized survivorship care plan (SCP) in improving cancer-related literacy among childhood cancer survivors, and to identify characteristics of survivors who demonstrated minimal gain from the intervention. METHODS: We recruited survivors diagnosed with cancer at ≤18 years old and were >2 years post treatment. The intervention included a personalized SCP and 30-minute health risk counseling. The participants' knowledge of their cancer diagnosis and potential treatment-related late effects (LEs) was assessed at baseline, immediately post intervention, and 1-3 months post intervention. Generalized estimating equation was used to test for changes in the awareness scores, with interacting terms (time*factor) added to identify differences in the score trajectory across clinically relevant subgroups. RESULTS: In total, 248 survivors completed the intervention (mean age: 19.4 [SD = 6.7] years; 54.1% male; 66.1% hematological malignancies), of whom 162 completed all assessments. There was significant increase in survivors' awareness of their cancer diagnoses (mean adjusted score: baseline 66.9, post intervention 86.3; p < .001) and potential LEs (baseline 30.9, post intervention 66.3; p < .001). The proportion of survivors who demonstrated awareness of their potential LEs increased from 9.7% to 54.3%. The interaction analysis showed that there was significantly less improvement in awareness among survivors of non-central nervous system (non-CNS) solid tumors (p = .032), lower socioeconomic status (p = .014), and parents of pediatric survivors (vs. adult survivors; p = .013). CONCLUSIONS: The provision of a personalized SCP showed preliminary effectiveness in improving survivors' understanding of their treatment-related LEs. Health counseling with SCP should be reinforced in vulnerable subgroups. Future work includes evaluating its long-term impact on lifestyle and health outcomes.

Perceptions of Infertility Risk Among Chinese Parents of Children with Cancer: A Qualitative Study.

Objective: Anticancer treatment may be associated with damage to the reproductive organs and risk of infertility in children with cancer. The collectivist cultural norms of Asian societies may lead Chinese parents to have unique concerns regarding infertility. This qualitative study explored the perceptions of infertility risk and parenthood among parents of childhood cancer survivors in Hong Kong. Methods: Thirteen parents were recruited via a snowball sampling approach from a nongovernmental organization in Hong Kong, representing nine survivors of childhood cancer (leukemia n = 5, solid tumors n = 4). The in-depth semistructured interviews were audiotaped and transcribed verbatim. A thematic analysis was performed using ATLAS.ti 8. Results: Parents mostly perceived their children's fertility status as a distant concern (n = 11, 85%) but emphasized the need for timely information from clinicians when their children reach young adulthood (n = 8, 62%). They reported receiving inconsistent fertility information from different oncology practitioners (n = 9, 69%). A few parents acknowledged that under the influence of the Chinese culture, their children, especially sons, have an important duty to continue the family lineage. However, even if the cancer treatment were associated with infertility risk, almost all parents (n = 12, 92%) stated that it would still not affect their willingness to let their child undergo treatment because survival and cure were still their highest priority. Conclusion: Our findings suggest the need to proactively provide fertility information to parents both during active treatment and when survivors reach reproductive age. Future studies should evaluate the benefits of developing culturally relevant decision-making aids to address parents' informational needs regarding fertility issues.

Technology Acceptance Among Patients With Hemophilia in Hong Kong and Their Expectations of a Mobile Health App to Promote Self-management: Survey Study.

BACKGROUND: The lifelong management of hemophilia is demanding and complex. In July 2019, we published a review in the Journal of Medical Internet Research, summarizing telehealth interventions that facilitate monitoring of bleeding events and promoting the appropriate use of clotting factors among patients with hemophilia. This work has led to the development of a community program that aims to harness technology to promote self-management among patients with hemophilia in Hong Kong. OBJECTIVE: Before the inception of this program, we conducted a cross-sectional survey to evaluate the patients' level of technology acceptance and identify their expectations of the use of mobile technology for self-management of hemophilia. METHODS: In total, 56 participants (75% adult patients and 25% parents of pediatric patients; 87.5% with moderate to severe disease) were recruited from a local nongovernmental organization that serves patients with hemophilia. They rated their perceived confidence and acceptance in using the new mobile technology (score 1 to 5 for each item, with a higher score indicating better acceptance) using a structured questionnaire (adapted from the Technology Acceptance Model). They also identified the top features that they perceived to be the most important components of a mobile app for the self-management of hemophilia. The Mann-Whitney U test was used to compare technology acceptance scores across subgroups of different clinical and socioeconomic characteristics. RESULTS: In general, the participants considered themselves skilled in using mobile apps (mean 4.3, 95% CI 4.1-4.5). They were willing to learn to use the new mobile app to organize their bleeding records (mean 4.0, 95% CI 3.7-4.3) and to manage their health (mean 4.2, 95% CI 4.1-4.5). Participants who lived in public housing (a surrogate marker for lower socioeconomic status in Hong Kong) reported lower technology acceptance than those who lived in private housing (P=.04). The most important features identified by the participants concerned documenting of infusion logs (n=49, 87.5%), bleeding events (n=48, 85.7%), and the secure delivery of the bleeding information to health care professionals (n=40, 71.4%). CONCLUSIONS: It is encouraging to infer that patients with hemophilia in Hong Kong are receptive to the use of mobile health technology. The findings of this survey are applicable in designing the key features of a patient-centered, multimodal program harnessing mobile technology to promote self-management among patients with hemophilia. Future studies should evaluate participants' acceptability and perceived usability of the mobile app via user metrics and assess clinical and humanistic outcomes of this program.

Comparison between daily and on-demand PrEP (pre-exposure prophylaxis) regimen in covering condomless anal intercourse for men who have sex with men in Hong Kong: A randomized, controlled, open-label, crossover trial.

INTRODUCTION: Both daily and on-demand regimens have been proven effective for pre-exposure prophylaxis (PrEP) against HIV in men who have sex with men (MSM). We aimed to compare the two regimens on their coverage of condomless anal intercourse (CLAI) in MSM. METHODS: A randomized, controlled, open-label, crossover trial was conducted in a teaching hospital in Hong Kong. Participants were sexually active HIV-negative MSM aged 18 years or above with normal renal function and without chronic hepatitis B infection. Oral tenofovir disoproxil fumarate 300 mg/emtricitabine 200 mg (TDF/FTC) tablets were prescribed for PrEP. After a 2-week lead-in with daily TDF/FTC for treatment-naïve MSM for tolerance assessment, participants were randomly assigned in a 1:1 ratio with a block size of four to either daily-first or on-demand-first arm based on the IPERGAY study, for receiving PrEP for 16 weeks, then crossed-over to the alternative regimen for another 16 weeks. The primary outcome was the proportion of days with PrEP-covered CLAI by intention-to-treat analysis. The trial is registered with the CCRB Clinical Trials Registry, CUHK, CUHK_CCRB00606, and is closed to accrual. RESULTS: Between 25 August 2018 and 23 March 2019, 119 eligible participants were assigned to daily-first arm (n = 59) and on-demand-first arm (n = 60) with an 87% overall completion rate (n = 103). With 96% and 54% of days on PrEP during daily and on-demand periods, respectively, the proportion of days with PrEP-covered CLAI between two arms were not statistically different (92% vs. 92%, p = 0.93). About half (47%) were diagnosed with at least one episode of incident sexually transmitted infection. Mild and time-limited adverse events, including diarrhoea, headache, nausea and dizziness, were reported in 37 (31%) and 10 (8%) during the daily and on-demand periods, respectively. At the end of the study, a similar proportion favoured daily or on-demand regimen. CONCLUSIONS: High prevention-effective adherence, as reflected from the coverage of CLAI, was achievable by either daily or on-demand PrEP among MSM, albeit a higher number of tablets taken for daily PrEP. As both regimens were well accepted, a flexible approach adopting either or both regimens with possible switching is warranted in order to suit individual health needs.

Transition from Acute Treatment to Survivorship: Exploring the Psychosocial Adjustments of Chinese Parents of Children with Cancer or Hematological Disorders.

OBJECTIVES: Parents of children diagnosed with critical illnesses face multiple challenges during their caregiving experience. However, relevant studies have been limited in the Chinese context. Guided by the stress and coping model, we conducted a qualitative study to identify the stressors, coping strategies, and adjustment experiences of Hong Kong parents of children with cancer or hematological disorders. METHODS: We recruited 15 parents of children with cancer or hematological disorders requiring bone marrow transplantation and were currently >2 years post-treatment. They participated in a 30-min semi-structured interview. Thematic analysis was performed using the grounded theory approach. RESULTS: The stressors reported by parents included a high caregiving burden during their children's diagnosis and treatment stages. The fear of recurrence, the need for information, and concerns about late effects were also common among the parents during their children's transition/survivorship stage. To cope with these stressors, the parents commonly used problem-focused (e.g., seeking help from professionals and support groups) and emotion-focused (e.g., behavioral distractions, venting, and crying) strategies. Despite these stressors, parents reported positive changes through the caregiving experience, such as improved family relationships, developing health-protective habits, and the reprioritization of different aspects of life. CONCLUSIONS: Parents encounter different stressors during the cancer care continuum. Using different coping strategies, parents experience positive changes amidst caregiving. Future studies should explore culturally relevant adaptive coping strategies to enhance parents' psychosocial adjustment.

Medication Management Service for Old Age Homes in Hong Kong Using Information Technology, Automation Technology, and the Internet of Things: Pre-Post Interventional Study.

BACKGROUND: Innovation in technology and automation has been increasingly used to improve conventional medication management processes. In Hong Kong, the current practices of medication management in old age homes (OAHs) are time consuming, labor intensive, and error prone. To address this problem, we initiated an integrated medication management service combining information technology, automation technology, and the Internet of Things in a cluster network of OAHs. OBJECTIVE: This pilot study aimed to evaluate the impact of the medication management program on (1) medication management efficiency, (2) medication safety, and (3) drug wastage in OAHs. We compared the time efficiency and the reductions in medication errors and medication wastage in OAHs before and at least 2 weeks after the implementation of the program. METHODS: From November 2019 to February 2020, we recruited 2 OAHs (serving 178 residents) in Hong Kong into the prospective, pre-post interventional study. The interventional program consisted of electronic medication profiles, automated packaging, and electronic records of medication administration. Using 3-way analysis of variance, we compared the number of doses prepared and checked in 10-minute blocks before and after implementation. We received anonymous reports of medication errors from OAH staff and analyzed the results with the Fisher exact test. We also calculated the quantity and cost of wasted medications from drug disposal reports. RESULTS: The number of doses prepared and checked in 10-minute blocks significantly increased postimplementation (pre: 41.3, SD 31.8; post: 70.6, SD 22.8; P<.001). There was also a significant reduction in medication errors (pre: 10/9504 doses, 0.1%; post: 0/5731 doses; P=.02). The total costs of wasted medications during January 2020 in OAH 1 (77 residents) and OAH 2 (101 residents) were HK $2566.03 (US $328.98) and HK $5249.48 (US $673.01), respectively. CONCLUSIONS: Our pilot study suggested that an innovative medication management program with information technology, automation technology, and Internet of Things components improved the time efficiency of medication preparation and medication safety for OAHs. It is a promising solution to address the current limitations in medication management in OAHs in Hong Kong.

Vancomycin Prescribing Practices and Therapeutic Drug Monitoring for Critically Ill Neonatal and Pediatric Patients: A Survey of Physicians and Pharmacists in Hong Kong.

Background: Deviations from the optimal vancomycin dosing may occur in the neonatal and pediatric population due to inconsistencies in the recommended dosing algorithms. This study aims to collect the expert opinions of clinicians who practice in the neonatal or pediatric intensive care units (NICU/PICUs) of 12 major medical centers in Hong Kong. Methods: This was a multicenter, cross-sectional study. Eligible physicians and pharmacists completed a structured questionnaire to identify the challenges they encountered when selecting the initial intermittent vancomycin dosing. They also answered questions concerning therapeutic monitoring services (TDM) for vancomycin, including the targeted trough levels for empirical vancomycin regimens administered for complicated and uncomplicated infections. Results: A total of 23 physicians and 43 pharmacists completed the survey. The top clinical parameters reported as most important for determining the initial vancomycin dosing were renal function (90.9%), post-menstrual/postnatal age (81.8%), body weight (66.7%), and suspected/documented pathogen (53.0%). Respondents reported challenges such as difficulties in determining the optimal initial dose for a targeted level (53.0%), inconsistencies between dosing references (43.9%) and a lack of clear hospital guidelines (27.3%). Half of the pharmacists (48.8%) reported that they had helped to interpret the TDM results and recommend vancomycin dose adjustments in >75% of cases. For methicillin-resistant Staphylococcus aureus infection, physicians, and pharmacists reported target trough levels of ~10-15 and 15-20 mg/L, respectively. For suspected moderate/uncomplicated Gram-positive infections physicians tended to prefer a lower trough range of 5-10 mg/L, while pharmacists preferred a range of 10-15 mg/L. Conclusions: Our results demonstrate that clinicians used varying vancomycin dosing guidelines in their practices. The multidisciplinary TDM service in Hong Kong can be improved further by establishing a standardized dosing guideline and implementing a well-structured, evidence-based service protocol. Future work includes conducting drug utilization studies to evaluate real-world antimicrobial usage patterns and the impact on tangible clinical outcomes, and developing pharmacokinetic-guided dose calculator for antimicrobials in critically ill neonates and pediatric patients.

Pharmacists' Perceptions of the Benefits and Challenges of Electronic Product Information System Implementation in Hong Kong: Mixed-Method Study.

BACKGROUND: With the advancement of technology, more countries are now adopting the use of electronic product information (ePI), which refer to an electronic version of physical product inserts in a semistructured format optimized for electronic manipulation. The successful implementation of ePI has led to advantages and convenience to patients, health care professionals, and pharmaceutical companies in many regions and countries. In the Hong Kong Special Administrative Region (SAR), there is currently no citywide implementation of ePI. The SAR exhibits conditions that would favor the implementation of an ePI system, as well as existing barriers hindering its implementation. However, no study has been performed to examine the specific situation in Hong Kong. OBJECTIVE: The objective of this study is to explore working pharmacists' overall perception of ePI and to identify potential challenges to the implementation of an ePI system in Hong Kong. METHODS: This mixed-method study involved a structured survey and interview with practicing pharmacists in Hong Kong. Pharmacists were eligible if they were licensed to practice in Hong Kong, and currently working locally in any pharmacy-related sectors and institutions. Respondents completed a survey to indicate their level of agreement with statements regarding the potential advantages of ePI over paper PI. A structured interview was conducted to gather respondents' perceived advantages of ePI over paper PI in different aspects, such as professionalism, usability, presentation, and environment, as well as challenges of citywide ePI implementation in Hong Kong. Thematic analysis was adopted to analyze the qualitative data. Grounded theory was used to generate themes and identify specific outcomes. RESULTS: A total of 16 pharmacists were recruited, comprising 4 community pharmacists, 5 hospital pharmacists, and 7 industrial pharmacists. All of them used electronic platforms at least once per month on average. Respondents identified many flaws in physical package inserts that can potentially be mitigated using ePI. The speed with which drug information can be retrieved and the degree to which the drug information can be readily updated and disseminated were considered the greatest strengths of ePI. The clarity with which ePI present drug information to patients was considered as the weakest aspect of ePI. Many respondents highlighted concerns about the security risks and high cost associated with system maintenance and that certain subpopulations may not be sufficiently computer literate to navigate the ePI system. Respondents also voiced many concerns about the implementation and maintenance of a local ePI system. CONCLUSIONS: We conclude that an ePI system is generally supported by pharmacists but concerns about implementation process and maintenance of the system has been raised. The perceived benefits of ePI gathered from this study, as well as collective evidence from other countries with mature ePI systems, confirm that more efforts should be made to promote optimized development and implementation of an ePI system in Hong Kong.

Telehealth Interventions for Improving Self-Management in Patients With Hemophilia: Scoping Review of Clinical Studies.

BACKGROUND: The introduction of home therapy for hemophilia has empowered patients and their families to manage the disease more independently. However, self-management of hemophilia is demanding and complex. The uses of innovative interventions delivered by telehealth routes such as social media and Web-based and mobile apps, may help monitor bleeding events and promote the appropriate use of clotting factors among patients with hemophilia. OBJECTIVE: This scoping review aims to summarize the literature evaluating the effectiveness of telehealth interventions for improving health outcomes in patients with hemophilia and provides direction for future research. METHODS: A search was conducted in Ovid MEDLINE, EMBASE, and PubMed databases for studies that (1) focused on patients with hemophilia A or B; (2) tested the use of remote telehealth interventions via the internet, wireless, satellite, telephone, and mobile phone media on patients and caregivers; and (3) reported on at least one of the following patient-/caregiver-focused outcomes related to empowering patients/caregivers to be active decision makers in the emotional, social, and medical management of the illness: quality of life, monitoring of bleeding episodes, joint damage or other measures of functional status, medication adherence, and patients' knowledge. Implementation outcomes (user metrics, cost saving, and accuracy of electronic records) were also evaluated. Reviews, commentaries, and case reports comprising ≤10 cases were excluded. RESULTS: Sixteen articles fulfilled the inclusion criteria. The majority of the interventions (10/16, 62%) evaluated both implementation outcomes and patient-/caregiver-focused outcomes. User performance and accuracy and comprehensiveness of electronic records were also measured in most studies (4/16, 87%). The components of the interventions were rather homogenous and typically involved electronic logging and reminders for prophylactic infusions, reporting of spontaneous and traumatic bleeding events, monitoring of infusion product usage and home inventory, and real-time communication with health care professionals and hemophilia clinics. Telemedicine-supported education and information interventions seemed to be particularly effective among adolescent and young adult patients. Although the patients reported improvements in their health-related quality of life and perception of illness, telemonitoring devices did not appear to have a significant effect on quantifiable health outcomes such as joint health. Longitudinal studies seemed to suggest that the response and adherence rates to recording decreased over time. CONCLUSIONS: Preliminary evidence from this review suggests that telehealth-delivered interventions could feasibly improve patients' adherence to medication use and promote independence in disease management. Given the complexity and resources involved in developing a mature and established system, support from a dedicated network of hemophilia specialists and data managers will be required to maintain the technology, improve adherence to prophylactic treatment and recording, and validate the electronic data locally.
