A better understanding of the factors influencing the QOL among patients with advanced illness can facilitate policy development, particularly in resource constrained countries [33]. Herrera and colleagues [34] remind us that PC provision should not be determined by the patient’s geographical location, his/ her disease, or ability to pay, but on needs alone. Other studies [35, 36] further support the contention that needs assessed deliberately among patients provides useful information to plan programmes and interventions that meet the explicit requirements of a local population. The findings of this study, although a relatively small sample, when combined with the findings from the other concurrent studies among family members and health care professionals, are fundamental to informing the development of PC services in Bhutan.
Forty two percent of the patients in the study had advanced cancer. Cancer in Bhutan has increased from 923 new cases in 2013 to 1,824 in 2017. Cancer is identified as a major threat to public health in the developing countries [37]. The remaining 58% were diagnosed with advanced, non-malignant diseases including both communicable and chronic diseases. In 2017, along with 144 cancer deaths, 212 deaths related to heart disease, 166 to alcoholic liver disease and 39 to chronic kidney disease were reported [25]. Substantial numbers of chronic patients also die at home without a cause of death being reported.
When diagnosed with cancer, both the patient and family experience a wide range of needs throughout the illness trajectory, ranging from physical needs to emotional, psychological, social, financial and spiritual needs [38]. The needs of patients with non-malignant conditions are now increasingly identified [39-41]. This research found that people diagnosed with advanced malignant and non-malignant illnesses in Bhutan have poor levels of functioning and varied levels of symptom severity indicating high support needs, consistent with advanced illnesses in other LMICs [33, 42-45]. There was no differences in symptom severity or level of functioning between cancer and non-cancer patients except for constipation (p value < 0.05). This is in contrast to a study of elderly cancer patients in Sweden who had poorer scores, more complaints and subsequently poorer quality of life compared to non-cancer patients [29].
There are no published studies of normative EORTC QLQ-C30 data among Asian PC populations. The existing normative data is most available for general populations and the mean scores for the Global Health/QOL across Australia (68.5, SD 21.5), Columbia, (77.1, SD 18.5), the European countries (66.1, SD 21.7) and Korea (67.7, SD 68.8) provide a picture of quality of life scores for those without advanced illness [46-49]. One study from Ethiopia [33] which focused on people mostly diagnosed with later stage cancer, reported a better mean global health/QOL score than patients with advanced illnesses in Bhutan (Ethiopia 54.6, SD 26.2 compared with Bhutan 47.4, SD 24.1) despite the mean score for pain in cancer patients in the two countries being similar (Ethiopia 55, SD 36.2, Bhutan 55.2, SD 35.7). Symptoms like fatigue and financial difficulties related to the illness are worse among Bhutanese cancer patients (59.4, SD 34.8 and 81.6, SD 36.3, respectively) compared to Ethiopian cancer patients (52.6, SD 36.1, and 67.1, SD 41.2, respectively) and much more than the general population in the aforementioned countries [33, 46-49]. These comparisons highlight the need for a model of PC in Bhutan which considers the social and economic context of patients in addition to their disease and symptom management priorities.
In this study, both cancer and non-cancer patients experienced moderate pain (mean 46.2, SD 37.1). Pain is one of the most common and feared symptoms experienced by patients with advanced illnesses [6], and can significantly influence the psychological and emotional wellbeing and overall QOL of both patients and families [50, 51]. In Bhutan, although oral morphine is available at all levels of healthcare except in BHU Grade II [52], it may be inadequately used as PC is an emerging concept [26]. Where PC is not well developed, several barriers to accessing morphine have been reported, including lack of availability, limited knowledge and opiophobia among physicians, along with a reluctance by patients and families to use it [53, 54]. The need to improve pain management is a priority area for new PC services in Bhutan.
Social problems were far reaching for participants, in addition to their medical condition. Most were married and many had young children. In one case the eldest child was just six years old and in another the youngest was just one. Parenthood is one of the major concerns when diagnosed with an advanced illness [55], however, the needs specific to dying patients and their dependent children are not well met even in the developed countries with comprehensive PC [56-58].
Forty one percent of participants in this study did not go to school and 13% had just primary education— indicating that 54% of the patients had significant problems with literacy. Literacy is an important concern in LMICs given its association with a range of adverse health outcomes [59]. Misinformation and misunderstandings related to PC and hospice services among indigenous populations [60] have emphasized public education as an integral component of PC which provides information, knowledge and skills enabling patients, particularly the marginalized and vulnerable groups, to adapt effectively when faced with the diagnosis of advanced illness [61]. Given the low levels of literacy in Bhutan and a lack of knowledge about PC, even amongst health professionals, education and raising awareness about PC is important for the public in Bhutan. Integrating PC modules in nursing colleges, postgraduate medicine, regular training programs for in-service health professionals combined with PC awareness initiatives for relevant stakeholders including policy makers are some of the important avenues to develop PC education. Use of national television, radio and other social media platforms can be good strategies to create awareness about PC in Bhutan.
Sixty one percent of the patients in this study did not have a reliable job or income, which was reflected in the high levels of financial stress for both cancer and non-cancer patients. Although healthcare in Bhutan, including referral abroad, is funded by the government [62], patients still need to pay for accommodation in private cabins instead of the general hospital ward which is noisy and privacy often compromised; for some medicines that are not included in the essential drug list; and for the services availed from the private diagnostic facilities both within and outside the country [22]. Patients incur expenditure on the repeated travel to and from the referral centres for the treatment and management of their illness. This situation is similar in other countries in the region where rural patients have to travel long distances for treatment and where illness and the time required for treatment further reduces incomes [63, 64]. Moreover, Bhutanese often spend huge amounts of money on rituals, prayers, offerings and other traditional healing practices when confronted with advanced illness because patients and family members strongly believe that diseases are caused by bad, vengeful spirits causing imbalances in the vital elements – bile, phlegm and wind channels, within the body [65, 66]. Traditional healing practices along with modern medicine are considered to provide parallel benefits in cancer management and end-of-life care, especially in developing countries [60, 67-69]. Having traditional medicine integrated into the national health system coupled with well informed and engaged local traditional healers can play a significant role in advancing PC in Bhutan.
Consistent with previous research in both developed and developing countries [28, 42-45, 70, 71], both cancer and non-cancer patients in Bhutan have varied needs throughout their illness that affects their overall QOL—ranging from physical symptom control to psychological, emotional, cognitive and spiritual support, as well as the need for food and financial assistance. Patients also had information needs about diagnosis, treatment options and side effects along with the need for psychological and spiritual support [35, 72].
Palliative care aims to address the broad range of symptoms and needs of patients with advanced illnesses described in our study. When assessing PC needs for a country or a region, it is vital to understand the benefit of such programmes to the local population [73]. The WHO recommends that a PC service should, at a minimum, identify both cancer and non-cancer patients who could benefit from PC; assess, reassess and address their physical, psychological, social, emotional and spiritual distress and determine culturally appropriate goals of care [6]. In rural Africa, PC integrated into disease-modifying therapies and into the routine HIV services have reduced physical pain and improved psychosocial and spiritual wellbeing including socioeconomic assistance for most patients [74, 75]. Concurrent PC among advanced cancer patients is perceived by oncologists to improve the quality of life of patients and families, facilitate better quality of care with less aggressive end-of-life care, and reduce emotional distress [76]. Given that PC is a young concept in Bhutan, these findings are relevant and applicable to the Bhutanese context as education and awareness programs are crucial to introducing PC services.
Patients with advanced illnesses in this study were admitted to the hospital many times since diagnosis, and the majority (59%) spent at least 2 weeks in hospital during each admission. Several studies [10, 18, 77, 78] have found that effective PC services can avoid repeated, often unnecessary, visits to emergency departments at the end-of-life. Palliative care services have also reduced long-term hospital admissions and the referral of patients abroad, thus reducing health care costs. Almost 40% of the health care expenses are known to occur in the last 3 months of life and account for almost 70% of end-of-life expenditures [79]. The government of Bhutan is challenged by the escalating cost of health care [22]. Integrating a public health approach to PC into the existing health care system can help manage the increasing costs.
While the principles of PC remain universal, the WHO and other international organizations reiterate that PC models should be contextually appropriate [1, 8, 9]. Modified to its social, cultural, spiritual and economic context, even resource constrained countries like Bhutan can provide effective PC services as demonstrated by Kerala in India, Arusha in Tanzania, Brasov in Romania, Vietnam and Argentina [1, 80, 81].
Strengths and limitations
There are several strengths and limitations to this study. Bhutan has varying cultural and belief systems in response to advanced illness, death and dying and post-death rituals. A strength of this study was the inclusion of participants from all regions across the country. Although a sample size of 70 participants is small, the challenges faced to hear those 70 voices were great, and the study would be difficult to repeat for someone not fluent in the local dialects. The small sample size limited the inferential statistics to compare between cancer and non-cancer participants. One of the limitations was the use of only the EORTC-QLQ-30 which resulted in a reduced understanding of other needs such as information, spiritual and sexual needs of the patients. Due to complex practicalities including low literacy, issues with translation and the potential for encountering cultural taboos, we foresaw difficulties in using multiple tools and chose to use just one to maximise participation. This was also the first research conducted with this population in Bhutan. Future studies could consider a bigger sample and include other tools to explore additional needs in such patients.
