A type III effectiveness-implementation hybrid evaluation of a multicomponent patient navigation strategy for advanced-stage Kaposi's sarcoma: protocol

Background

For people with advanced-stage Kaposi’s sarcoma (KS), a common HIV-associated malignancy in sub-Saharan Africa, mortality is estimated to be 45% within 2 years after KS diagnosis, despite increasingly wide-spread availability of antiretroviral therapy and chemotherapy. For advanced-stage KS, chemotherapy in addition to antiretroviral therapy improves outcomes and saves lives, but currently, only ~50% of people with KS in western Kenya who have an indication for chemotherapy actually receive it. This protocol describes the evaluation of a multicomponent patient navigation strategy that addresses common barriers to service penetration of and fidelity to evidence-based chemotherapy among people with advanced-stage KS in Kenya.

Methods

This is a hybrid type III effectiveness-implementation study using a non-randomized, pre- post-design nested within a longitudinal cohort. We will compare the delivery of evidence-based chemotherapy for advanced-stage KS during the period before (2016–2020) to the period after (2021–2024), the rollout of a multicomponent patient navigation strategy. The multicomponent patient navigation strategy was developed in a systematic process to address key determinants of service penetration of and fidelity to chemotherapy in western Kenya and includes (1) physical navigation and care coordination, (2) video-based education, (3) travel stipend, (4) health insurance enrollment assistance, (5) health insurance stipend, and (6) peer mentorship. We will compare the pre-navigation period to the post-navigation period to assess the impact of this multicomponent patient navigation strategy on (1) implementation outcomes: service penetration (chemotherapy initiation) and fidelity (chemotherapy completion) and (2) service and client outcomes: timeliness of cancer care, mortality, quality of life, stigma, and social support. We will also describe the implementation process and the determinants of implementation success for the multicomponent patient navigation strategy.

Discussion

This study addresses an urgent need for effective implementation strategies to improve the initiation and completion of evidence-based chemotherapy in advanced-stage KS. By using a clearly specified, theory-based implementation strategy and validated frameworks, this study will contribute to a more comprehensive understanding of how to improve cancer treatment in advanced-stage KS.

Competencies for Nurses Regarding Psychosocial Care of Patients With Cancer in Africa: An Imperative for Action

Psychosocial care is considered an important component of quality cancer care. Individuals treated for cancer can experience biologic or physical, emotional, spiritual, and practical consequences (eg, financial), which have an impact on their quality of living. With the establishment of cancer centers in Africa, there is growing advocacy regarding the need for psychosocial care, given the level of unmet supportive care needs and high emotional distress reported for patients. Nurses are in an ideal position to provide psychosocial care to patients with cancer and their families but must possess relevant knowledge and skills to do so. Across Africa, nurses are challenged in gaining the necessary education for psychosocial cancer care as programs vary in the amount of psychosocial content offered. This perspective article presents competencies regarding psychosocial care for nurses caring for patients with cancer in Africa. The competencies were adapted by expert consensus from existing evidenced-based competencies for oncology nurses. They are offered as a potential basis for educational program planning and curriculum development for cancer nursing in Africa. Recommendations are offered regarding use of these competencies by nursing and cancer program leaders to enhance the quality of care for African patients with cancer and their family members. The strategies emphasize building capacity of nurses to engage in effective delivery of psychosocial care for individuals with cancer and their family members.

The Value of Navigators in Breast Cancer Management in a South African Hospital

BACKGROUND

Specialist breast cancer nurses (BCNs) have improved the psychological care and follow-up rates of breast cancer (BC) patients. This study sought to determine if breast cancer research workers (BCRWs) as de facto BCNs impacted patients' adherence to treatment by comparing groups with and without these patient navigators; hence assessing our need for BCNs.

METHODS

Two groups BC patients booked for primary chemotherapy compared. Study group 1 (SG1): no BCRWs/BCNs. Study group 2 (SG2): BCRWs involvement. Assessment of numbers completing primary chemotherapy, undergoing surgery post-neoadjuvant chemotherapy and BCRWs interventions.

RESULTS

SG1: n = 281, 25-89y, mean 52.7y, Stage 4: 35.6%, Stage 3: 64.4%. SG2: n = 154, 21-85y, mean 52.6y, Stage 4: 47.4%, Stage 3: 43.3%, Stage 2: 9%. Primary chemotherapy not completed SG1: 40.2% (113) versus SG2: 13.5% (21); p < 0.00001. SG1: 88% not completing were lost to follow-up. Excluding peri-chemotherapy deaths and discontinuation: SG1: 37.1% did not complete chemotherapy versus SG2: 2.6%, p < 0.00001. SG2: BCRWs: 107 interventions for 58 (37.7%) patients. Therapeutic breast surgery SG1: 103/181 (56.9%) versus SG2: 66/81 (81.5%); p < 0.0001. SG1: main reasons for not having surgery: lost to follow-up during (n = 58) or after (n = 9) chemotherapy. Follow-up SG2: 12-43 months, mortality: 52% (80/154), no lost to follow-ups. SG1: No mortality data.

CONCLUSIONS

In our setting, BC patients often do not attend or complete treatments. In this study, BCRWs as de-facto BCNs were beneficial for BC patient care, improving chemotherapy compliance and therapeutic surgical interventions. This highlights the need for BCNs for the management of BC patients in South Africa.

Healthcare delivery interventions to reduce cancer disparities worldwide

Globally, cancer care delivery is marked by inequalities, where some economic, demographic, and sociocultural groups have worse outcomes than others. In this review, we sought to identify patient-facing interventions designed to reduce disparities in cancer care in both high- and low-income countries. We found two broad categories of interventions that have been studied in the current literature: Patient navigation and telehealth. Navigation has the strongest evidence base for reducing disparities, primarily in cancer screening. Improved outcomes with navigation interventions have been seen in both high- and low-income countries. Telehealth interventions remain an active area of exploration, primarily in high income countries, with the best evidence being for the remote delivery of palliative care. Ongoing research is needed to identify the most efficacious, cost-effective, and scalable interventions to reduce barriers to the receipt of cancer care globally.
