Participants
We were able to interview a total of 31 participants in this qualitative study, exceeding the number of participants needed to achieve saturation. The first group (with IO experience) consisted of 16 healthcare professionals (i.e., BMDs (n = 4), TCMPs (n = 4), nurses (n = 4), and healthcare administrators (n = 4)) and four caregivers. The second group (without IO experience) comprised another 11 healthcare professionals (i.e., BMDs (n = 3), TCMPs (n = 4), nurses (n = 2), and pharmacists (n = 2, of which one is dual qualified in Chinese herbal and conventional pharmacy)). We invited the two pharmacists after completing the first few interviews, where participants expressed that it was essential to consider the views of local pharmacists as they are likely to play a role in IO service delivery. Table 1 presents participants’ professional and demographic characteristics.

Stage 1. Implementation determinants of outpatient Integrative Oncology service delivery in Hong Kong
Qualitative data analysis generated 19 themes of implementation determinants, and we mapped all identified themes to at least one of the three components of the COM-B system, as well as ten of the 14 TDF domains. The three common international themes identified from the 31 interviews were:
-
lack of recognition among healthcare professionals, patients, and caregivers on the evidence supporting the safety and effectiveness of IO interventions (mentioned in 31 interviews);
-
lack of knowledge among healthcare professionals and healthcare administrators regarding IO (mentioned in 27 interviews); and
-
inefficient interprofessional communication and collaboration system (mentioned in 16 interviews)
The three common local themes identified were:
-
lack of nursing and administrative manpower supporting IO service delivery (mentioned in 30 interviews);
-
lack of awareness of IO services among healthcare professionals, healthcare administrators, patients, and caregivers (mentioned in 29 interviews); and
-
lack of knowledge among healthcare professionals regarding herb–drug interaction and herbal toxicities (mentioned in 28 interviews)
Table 2 illustrates all implementation determinants summarised from the interviews. For substantiating further discussion, we asterisked (*) these six important themes listed above and described them in-depth with relevant quotes extracted from the transcripts below.

#Local key themes frequently mentioned by the participants |
Knowledge
*Common local theme: lack of awareness of IO services among healthcare professionals, healthcare administrators, patients, and caregivers. In Hong Kong, lacking awareness of IO services was highlighted as one of the key reasons explaining why healthcare professionals and administrators do not deliver or adopt IO services in their daily practice. It might also explain why patients and caregivers do not use or recommend IO services. The common cultural practice of consuming Chinese herbal soups and consulting TCMPs for health maintenance does not necessarily contribute to the establishment or usage of IO services. We found that as many as 90.0% of participants with; and 100% without IO experience mentioned this particular issue.
“When we consulted BMDs for the first time, there was no information about IO posted in the oncology clinics, nor there was information provided by the nurses. It is always better to have advertisements or promotion leaflets available for patients because they might think: “Oh, TCM and TCMPs may help!” Perhaps many patients and caregivers are frustrated about not having authoritative information about IO services.” – a caregiver with IO experience.
“While TCM culture heavily influences our dietary habits like the regular consumption of Chinese herbal soups, its’ influence on healthcare service choice is unclear. When it comes to cancer management, I think both healthcare professionals, caregivers or patients have no idea about what exactly constitutes integrative oncology and how we can provide or use such services.” – a nurse without IO experience.
*Common local theme: lack of knowledge among healthcare professionals regarding herb–drug interactions and herbal toxicities. From the interviews, we identified that 100% of participants with; and 72.7% without IO experience expressed that lack of knowledge among healthcare professionals (BMDs in particular) regarding herb–drug interactions and herbal toxicities is a significant implementation barrier. Healthcare professionals are worried about the potential harms incurred to patients during the concurrent use of Chinese herbs and conventional cancer treatments like chemotherapies. However, patients and caregivers are less concerned, and they may not disclose their concurrent use of Chinese herbal medicine to avoid opposition from their BMDs.
“In Clinical Oncology settings, most, if not all, oncologists oppose the oral administration of Chinese herbal medicine during anticancer treatments. There is a lack of safety data regarding the potentially harmful interactions between concurrent oncology and herbal treatments. – a BDM with IO experience.
“The patient must have a certain level of white blood cells to continue chemotherapies. Also, we may need to rely on granulocyte colony-stimulating factors (G-CSFs) to boost the white blood cell level. Many patients expressed that the side effects of G-CSFs, including bone pain and fever, are unbearable and this may affect chemotherapy adherence. I think Chinese herbal medicine helps us strengthen our immune functions by elevating the white blood cell level with little to no side effects. Meanwhile, I am worried about BMDs’ disapproval of using Chinese herbs during chemotherapies due to the limited evidence on harmful interactions. Or else, I would have to lie to the BMD by not telling them that the patient consumed Chinese herbs.” – a caregiver without IO experience.
*Common international theme: lack of knowledge among healthcare professionals and healthcare administrators regarding IO. The knowledge among healthcare professionals (BMDs and nurses in particular) about IO is essential for its implementation, given their dominant roles in the Hong Kong healthcare system. Since nurses are expected to play a pivotal role in coordinating BMDs and TCMPs collaboration, and performing the instructions placed by the two parties, having specialised knowledge in TCM and IO is paramount for them to carry out these tasks with confidence. It is even expected that they will be able to spot potential herb–drug interactions by examining both conventional medicine and Chinese herbal medicine prescriptions. In Hong Kong, healthcare professionals’ scepticism towards IO due to the lack of relevant knowledge reduced BMDs’ and nurses’ willingness to participate in IO service delivery.
“As you call it “integrative oncology”, all parties [nurses, BMDs and TCMPs] must have a common language of communication. In Hong Kong, nursing students receive training in conventional medicine only, and nurses know nothing about TCM. If they do not receive relevant training on TCM or IO, they are unable to understand what TCMPs are doing to the patients. If we want to make nurses the coordinators between BMDs and TCMPs in IO service delivery, and the implementors of IO nursing procedures, we must provide them with adequate training and ensure that they at least understand Chinese herbal prescriptions.” – a nurse without IO experience.
Theme: lack of content regarding interprofessional collaboration between TCM, conventional medicine, and nursing in undergraduate education. 80.0% of participants with; and 72.7% without IO experience expressed that lacking credit-bearing modules on interprofessional collaboration skills in undergraduate TCM, medical, and nursing curriculums hindered interprofessional collaboration in IO service delivery.
Memory, attention, and decision processes
Theme: difficulties in decision-making among patients and caregivers on IO utilisation. 45.0% of participants with; and 63.6% without IO experience thought that having inadequate information or knowledge to support medical decision-making is a barrier to IO service utilisation among patients and caregivers.
Skills
Theme: lack of skills among healthcare professionals in delivering IO services. 80.0% of participants with; and 81.8% without IO experience reported that lacking skill in IO can demotivate TCMPs, BMDs, and nurses in IO service delivery.
Motivation (COM-B component)
Overall, eight themes were relevant to the motivation component of the COM-B system, covering five TDF domains (beliefs about consequences; social/professional role and identity; intention; reinforcement; and emotion) [Table 4]. This component included one common international theme.

*Common key themes also identified in a previous systematic review [BMJ Support Palliat Care 2023 May 12;spcare-2022-004150] of international literature on IO service implementation determinants |
Beliefs about consequences
*Common international theme: lack of recognition among healthcare professionals, patients, and caregivers on the evidence supporting safety and effectiveness of IO interventions. TCM has not been studied using modern research methodologies until recent decades. BMDs and nurses in Hong Kong may not oppose the adoption of IO, but they always expect IO interventions to be supported by robust clinical evidence, especially on safety and effectiveness. Meanwhile, patients and caregivers, who are interested in IO, also want to gather evidence to convince their BMDs to collaborate with TCMPs, with the expectation that partnership between their BMDs and TCMPs would optimise outcomes.
“We collaborated with University X [a university in Hong Kong] on a clinical trial for assessing the effectiveness of TCM in cancer management. After several years of follow-up, we submitted the results to the oncologists in Hospital Y [a hospital in Hong Kong] for their reference. When they saw the results, they were like: “Oh! The evidence is objective.” They then started believing in TCM and initiated collaboration with us. Therefore, I think we need to go through a process of generating and promoting TCM clinical evidence, to let BMDs understand TCM and IO better. It is not only about TCMPs advocating “integration” and then BMDs will be happy to team up with us. We need to build trust.” – a healthcare administrator with IO experience.
Theme: lack of knowledge among healthcare professionals about the potential ethical or legal consequences of IO service delivery. 80.0% of participants with; and 81.8% without IO experience believed that TCMPs’, BMDs’, and nurses’ intention of delivering IO services might be affected by the lack of clear guidelines detailing ethical or legal consequences of IO service delivery.
Social/professional role and identity
Theme: failure among BMDs and nurses to recognise the compatibility of IO service delivery with their duties and responsibilities. 80.0% of participants with; and 90.9% without IO experience expressed that if BMDs and nurses do not recognise IO service delivery as one of their job duties and responsibilities, they found no reason to be proactive in carrying out such tasks.
Intention
Theme: lack of career prospects for TCMPs and nurses involved in IO service delivery. 60.0% of participants with; and 72.7% without IO experience thought that lacking a well-designed career progress roadmap is discouraging TCM and nurses from performing tasks in IO service delivery, as such efforts will not be recognised for promotion or pay rise.
Reinforcement
Theme: lack of motivation among healthcare professionals in delivering IO services. 85.0% of participants with and 72.7% without IO experience reported that lacking motivation, in general, might influence TCMPs’, BMDs’, and nurses’ attitudes towards playing an active role in delivering IO services.
Emotion
Theme: negative feelings among BMDs and nurses towards TCM and TCMPs. 60.0% of participants with; and 45.5% without IO experience believed that BMDs’ and nurses’ negative feelings, or even hostility, towards TCM and TCMPs is jeopardising interprofessional trust, hence discouraging them from delivering IO services.
Theme: feelings of being excluded by the conventional medicine-dominated healthcare system among TCMPs. 60.0% of participants with; and 54.5% without IO experience expressed that TCMPs’ feelings of being unwelcomed by the healthcare system dominated by conventional medicine might make them reluctant to participate in IO service delivery.
Theme: lack of emotional understanding among BMDs and nurses towards patients’ requests for IO referral. 40.0% of participants with; and 45.5% without IO experience thought that the lack of emotional understanding or empathy towards patients’ requests for referral to IO services amongst BMDs and nurses can discourage their recommendation of IO services to patients and caregivers.
Opportunity (COM-B component)
Overall, five themes were relevant to the motivation component of the COM-B system, covering two TDF domains (environment and resources; and social influences) [Table 5]. This component included one common international theme and one common local theme.

#Local key themes frequently mentioned by the participants |
Environment and resources
*Common local theme: lack of nursing and administrative manpower supporting IO service delivery. A total of 85.0% of participants with; and 81.8% without IO experience agreed that lacking nursing and administrative manpower is a major implementation barrier for IO. Echoing the key theme of the need of training specialised IO nurses, some expressed that the availability of nurses and administrative assistants with IO knowledge and skills will be a critical factor for the successful launch or scaling up of IO services.
“Of course, we need some more nurses for IO service delivery. However, most of the nurses in Hong Kong are only familiar with conventional medicine. You must provide them with specialised TCM training to equip them with IO knowledge and skills. Is there a role for TCM nurses? I am not sure. There is a need to find out what their competencies should be. Also, these specialised nurses should be more confident in triaging patients to IO services and introducing the details to patients. Without extra human resources, we must use our existing nurses who have already been occupied by heavy clinical and administrative tasks. If it is the case [i.e. no extra human resources], I think it is not ideal.” – a BMD with IO experience.
“Sometimes, giving us extra funding is not as useful as one imagines. All they [healthcare administrators] want is trained human resources. After all, they are going to hire people with the funding to help share nurses’ clinical tasks. There are also many administrative tasks required for a single IO referral. I know it is difficult to rely on those without medical backgrounds to perform clinical tasks, yet at least you can give them some administrative assistants to handle routine non-clinical tasks. I am not sure if BMDs would be happy to deliver IO services with an increased salary. However, I know they will be happy if you provide extra human resources.” – a healthcare administrator without IO experience
Theme: lack of structured referral mechanisms and clear operation procedures for IO service delivery. All the participants with; and 63.6% without IO experience reported that the lack of well-structured referral mechanisms to streamline patient referrals between BMDs and TCMPs presented as a major implementation barrier. Similarly, lacking detailed operation procedures that guide the collaborations between BMDs, TCMPs, and nurses decreased their motivation in IO service delivery.
Theme: unaffordability of IO services. 50.0% of the participants with and 36.4% without IO experience expressed that the cost of IO services might be one of the reasons why patients and caregivers choose not to use or recommend IO services.
Social influences
*Common international theme: inefficient interprofessional communication and collaboration system. Well-organised interprofessional communications help blur the borders between healthcare professionals and facilitate their collaborations. For instance, BMDs, TCMPs, and nurses may discuss whether the patient is eligible for IO services and whether they should be aware of any special concerns during IO treatment provision. Such communications may be realised by interdisciplinary meetings in specific and protected timeslots. However, when meetings are infeasible, shared electronic health record systems, are key to improving IO service quality as all parties would at least have access to records of all the treatments the patients are receiving.
“Whenever patients and caregivers visit our TCMP, we need to carry around a big binder containing all records of all the conventional treatments the patient is receiving currently, and in the past. Also, we need to jot down everything the oncologist said in every consultation for our TCMP’s reference. It will be much better for all parties if the BMDs and TCMPs have some kind of an online collaboration platform for interprofessional communications.” – a caregiver with IO experience
Stage 2. Implementation strategies addressing the common implementation determinants
The intervention functions, policy categories, BCTs, and implementation strategies for addressing the common implementation determinants identified from the interviews (i.e., common international themes and common local themes) are presented in Tables 3 to 5. Below, we will discuss the respective potential implementation strategies targeting the determinants.
Common international implementation determinants
Lack of recognition among healthcare professionals, patients, and caregivers of the evidence supporting safety and effectiveness of IO interventions
Potential implementation strategies – It is vital to provide the most up-to-date clinical evidence, preferably generated using rigour clinical research methodologies, to support interprofessional decision-making and improve stakeholders’ confidence in IO service delivery 33,34. Clinical evidence may also be incorporated into electronic health record systems with assisted decision-making functions to enhance the appropriateness and adherence 22. Similarly, clinical evidence on IO safety and effectiveness should be given to the general audience in plain language to help patients, caregivers, and the public make informed decisions on IO service utilisation 35. Appropriate dissemination of evidence will also empower them to have constructive discussions with their BMDs and TCMPs regarding their decisions to use IO services.
Lack of knowledge among healthcare professionals and healthcare administrators regarding IO
Potential implementation strategies – Healthcare professionals, especially BMDs and nurses, and healthcare administrators may not be willing to deliver IO services if they are not familiar with relevant interventions 36,37. Therefore, local authorities can arrange practical training programmes for them on a regular basis, to provide them with updated, actionable knowledge in the format of locally relevant clinical guidelines 38. Funding bodies, like the Hong Kong Chinese Medicine Development Fund 39, have been providing funding schemes to support TCM and IO research and development. Additional funding should be allocated to strengthen the creation and dissemination of IO clinical practice guidelines as this is considered to be key for evidence uptake and translation into real-world practice 40.
Inefficient interprofessional communication and collaboration system
Potential implementation strategies – Local authorities can develop a shared electronic health record system for collaborative IO service delivery. This provides an efficient communication platform for BMDs, TCMPs, and nurses to exchange and update patients’ information, and spares patients and caregivers from passing information back and forth between BMDs and TCMPs 22,41. Evidence suggests that both formal and informal bridge-building activities are effective in consolidating connectivity and fostering trust between professionals 41. Such activities may include journal clubs and mutual practice observations 42. With better professional relationships, BMD, TCMP and nurses are expected to be more willing to refer patients mutually and maintain efficient interprofessional communications 43,44.
Common local implementation determinants
Lack of nursing and administrative manpower supporting IO service delivery
Potential implementation strategies – Care coordination is critical to the day-to-day operation of IO services because BMDs and TCMPs may not be capable of keeping track of administrative arrangements, or triaging patients for appropriate IO interventions 45,46. To streamline IO service delivery and facilitate interprofessional collaborations, relevant local authorities can arrange additional funding to train, recruit, and retain nurses who are experienced in coordinating IO services. Besides nursing staff, administrative assistants should also be recruited or retained to handle administrative work incurred by patient referrals and triage.
Lack of awareness of IO services among healthcare professionals, healthcare administrators, patients, and caregivers
Potential implementation strategies – To build confidence among conventional healthcare professionals on the value of adding TCM to conventional care, a demonstration of how interprofessional collaboration works and how IO actually benefit patients with real-world data is essential. The public may not be familiar with current regulatory systems on TCMPs, and the malpractice complaint mechanisms in TCM practice. Such unfamiliarity may undermine the public’s confidence in TCM and IO services 43,47. Local authorities can devolve resources into educating the public on these regulatory measures via different media. Monitoring the price transparency of TCM and IO services is also necessary if patient subsidy schemes are available in the future to facilitate access among the needy 41.
Lack of knowledge among healthcare professionals regarding herb–drug interactions and herbal toxicities
Potential implementation strategies – local authorities can develop a publicly accessible online platform containing up-to-date knowledge on herb–drug interactions and herbal toxicities. To facilitate avoidance of negative herb–drug interactions and adverse effects, relevant evidence should be integrated into existing electronic health record systems and provide automated alerts when contra-indications or potential toxicities are detected. Pharmacists with dual qualifications in Chinese medicine and conventional pharmacy should also be recruited to help develop and update these clinical information systems regularly. They can also provide consultation services on the co-administration of Chinese herbal medicine and conventional treatment if deemed necessary in the management of complex patient cases. Real-world outcomes of co-administering Chinese herbal medicine and conventional treatment among cancer patients should also be investigated using existing data from electronic health records of the public healthcare system.
