Tuberculosis in older adults: case studies from four countries with rapidly ageing populations in the western pacific region

BACKGROUND

The Western Pacific Region has one of the fastest-growing populations of older adults (≥ 65 years) globally, among whom tuberculosis (TB) poses a particular concern. This study reports country case studies from China, Japan, the Republic of Korea, and Singapore reflecting on their experiences in managing TB among older adults.

FINDINGS

Across all four countries, TB case notification and incidence rates were highest among older adults, but clinical and public health guidance focused on this population was limited. Individual country reports illustrated a range of practices and challenges. Passive case finding remains the norm, with limited active case finding (ACF) programs implemented in China, Japan, and the Republic of Korea. Different approaches have been trialled to assist older adults in securing an early diagnosis, as well as adhering to their TB treatment. All countries emphasised the need for person-centred approaches that include the creative application of new technology and tailored incentive programs, as well as reconceptualisation of how we provide treatment support. The use of traditional medicines was found to be culturally entrenched among older adults, with a need for careful consideration of their complementary use. TB infection testing and the provision of TB preventive treatment (TPT) were underutilised with highly variable practice.

CONCLUSION

Older adults require specific consideration in TB response policies, given the burgeoning aging population and their high TB risk. Policymakers, TB programs and funders must invest in and develop locally contextualised practice guidelines to inform evidence-based TB prevention and care practices for older adults.

Nursing actions promoting adherence to tuberculosis treatment: scoping review

OBJECTIVE

To analyze actions promoting adherence to tuberculosis treatment that are being carried out by nurses in different countries.

METHOD

Scoping review with selection of articles on the subject in LILACS, MEDLINE, IBECS, BDENF, SciELO, CINAHL, Embase, Web of Science, and Scopus databases.

RESULTS

Forty studies, published between 2009 and 2020, allowed the identification of nursing actions in two thematic categories. In the category "Nursing care: TB patients' specific needs to promote adherence to treatment", actions involving clinical aspects, professionals' knowledge and skills, educational and relational processes were identified. In the category "The role of nursing in coping with the social determinants of health to promote adherence to treatment", interventions related to the strengthening of family and community support, the inclusion of socioeconomic issues in care plans, and respect for cultural differences were highlighted.

CONCLUSION

Nursing work directed to the adherence to disease treatment requires the development of technical, ethical and, above all, political skills, aiming to increase the success of the actions carried out by these professionals.

Patient-perceived treatment burden of tuberculosis treatment

Background

Treatment for tuberculosis lasts for a minimum of 6 months. The treatment burden experienced by patients in a low-incidence setting where directly observed therapy is the standard of care is not well-known.

Methods

Patients receiving tuberculosis treatment through the chest clinic at a tertiary hospital in Sydney, Australia, participated in a semi-structured interview. The interviews explored the treatment burden experienced by patients and possible solutions to ameliorate this burden. Interviews were conducted until data saturation was achieved. They were recorded, transcribed and analysed using NVivo 12 software.

Results

Twenty participants (80% male, mean age 40 years) with pulmonary (n = 13) and extra-pulmonary (n = 7) tuberculosis were interviewed. Participants experienced healthcare, financial, social and medication burdens along with lifestyle changes due to treatment. Medication intake was challenging due to the high number of pills, and 55% (n = 11) of patients experienced fatigue amongst other side effects. Patients found clinic-based directly observed therapy inconvenient, especially those working and/or studying. Suggestions to lessen treatment burden included reducing medication burden and better access to health services.

Conclusion

Tuberculosis treatment is associated with substantial treatment burden for patients. Measures to reduce treatment burden including alternative treatment delivery methods which are more accommodating to patients than clinic-based directly observed therapy, such as video directly observed therapy or partially self -administered treatment, should be considered on a case-by-case basis.
