Associations between HIV infection status, psychosocial factors, and adjuvant endocrine therapy adherence among South African women with early-stage breast cancer.

Purpose: We aimed to evaluate for associations between HIV status, psychosocial factors, and adjuvant endocrine therapy (AET) adherence in South African (SA) women with estrogen receptor positive (ER+) breast cancer (BC). Methods: We enrolled South African women with early-stage ER + BC in remission and prescribed tamoxifen or an aromatase inhibitor to the prospective observational study. We performed AET pill counts at enrollment, 12 weeks, and 24 weeks, and calculated adherence ratios of pills consumed between visits to days between visits. Women completed questionnaires on social support, attitude towards medication, health literacy, self-efficacy, mental health, and AET toxicity. We collected household wealth data. We used hierarchical linear (HLM) and structural equation modelling (SEM) to compare adherence ratios between women with and without HIV while adjusting for psychosocial factors. Results: We collected adherence data from 239 women, 63 (26.4%) with co-morbid HIV. Comparing women with and without HIV, median AET adherence ratio was 0.88 vs 0.89, respectively (HLM p = 0.31). In our SEM model for the full cohort, mental health, healthcare savvy, and side effect burden latent variables were not significantly associated with adherence. In the subgroup of women living with HIV, lower SES quintile (ß 0.04, SE 0.02, p = 0.08) and poorer mental health (ß -0.02, SE 0.01, p = 0.10) showed trends toward association with adherence. Conclusions: HIV status is not predictive of AET adherence among SA women with ER + BC, though decreasing SES status and increasing mental health symptoms are marginally associated with adherence in women with BC and HIV.

Validating an Instrument for Direct Patient Reporting of Distress and Chemotherapy-Related Toxicity among South African Cancer Patients.

Patient-reported outcome measures (PROM) for monitoring treatment toxicity improve quality of life (QoL) and clinical outcomes. However, no such PROMs exist for sub-Saharan African cancer patients. We aimed to validate the Patient Reported Symptoms-South Africa (PRS-SA) survey, a novel PROM for measuring distress and chemotherapy-related symptoms in South African cancer patients. We enrolled patients at the oncology clinic at Charlotte Maxeke Hospital, Johannesburg. At three separate visits, participants simultaneously completed the PRS-SA survey and several previously validated questionnaires. We constructed a receiver operator characteristics curve for distress levels predicting a Hospital Anxiety and Depression Scale (HADS) score ≥15. We evaluated construct validity for symptom items by comparing severity to the EORTC Core Quality of Life Questionnaire (QLQ-C30) summary score (Pearson correlation tests) and ECOG performance status (Mann-Whitney U tests). We assessed symptom item responsiveness by comparing change in severity to change in QLQ-C30 summary score and comparing standardized mean scores with negative, no, or positive change on the Global Impression of Change (GIC) questionnaire (Jockheere-Terpstra trend test). Overall, 196 participants with solid tumors completed instruments. A distress score of 4 had 82% sensitivity and 55% specificity for clinical depression/anxiety. All symptom items showed construct validity by association with either QLQ-C30 score or performance status (highest p = 0.03). All but cough showed responsiveness to change in QLQ-C30 score (highest p = 0.045). In South African cancer patients, the PRS-SA's stress scale behaves similarly to the distress thermometer in other populations, and the symptom items demonstrated construct validity and responsiveness. Of note, 46% and 74% of participants who completed the PRS-SA in English or isiZulu, respectively, required assistance reading half or more of the instrument.

Spiritual Care, Pain Reduction, and Preferred Place of Death Among Advanced Cancer Patients in Soweto, South Africa.

CONTEXT: When religious and spiritual (R/S) care needs of patients with advanced disease are met, their quality of life (QoL) improves. We studied the association between R/S support and QoL of patients with cancer at the end of life in Soweto, South Africa. OBJECTIVES: To identify R/S needs among patients with advanced cancer receiving palliative care services and to assess associations of receipt of R/S care with patient QoL and place of death. METHODS: A prospective cohort study conducted from May 1, 2016 to April 30, 2018 at a tertiary hospital in Soweto, South Africa. Nurses enrolled patients with advanced cancer and referred them to the palliative care multidisciplinary team. Spiritual counselors assessed and provided spiritual care to patients. We compared sociodemographic, clinical, and R/S factors and QoL of R/S care recipients and others. RESULTS: Of 233 deceased participants, 92 (39.5%) had received R/S care. Patients who received R/S care reported less pain (2.82 ± 1.23 vs. 1.93 ± 1.69), used less morphine, and were more likely to die at home than patients who did not (57.5% compared with 33.7%). On multivariate logistic regression analysis, adjusting for significant confounding influences and baseline African Palliative Care Association Palliative care Outcome Scale scores, receipt of spiritual care was associated with reduced pain and family worry (odds ratio 0.33; 95% CI 0.11-0.95 and odds ratio 3.43; 95% CI 1.10-10.70, respectively). CONCLUSION: Patients with cancer have R/S needs. R/S care among our patients appeared to improve their end-of-life experience. More research is needed to determine the mechanisms by which R/S care may have improved the observed patient outcomes.

A Prospective Cohort Study of Factors Associated With Place of Death Among Patients With Late-Stage Cancer in Southern Africa.

CONTEXT: Identifying factors that affect terminally ill patients' preferences for and actual place of death may assist patients to die wherever they wish. OBJECTIVE: The objective of this study was to investigate factors associated with preferred and actual place of death for cancer patients in Johannesburg, South Africa. METHODS: In a prospective cohort study at a tertiary hospital in Johannesburg, South Africa, adult patients with advanced cancer and their caregivers were enrolled from 2016 to 2018. Study nurses interviewed the patients at enrollment and conducted postmortem interviews with the caregivers. RESULTS: Of 324 patients enrolled, 191 died during follow-up. Preferred place of death was home for 127 (66.4%) and a facility for 64 (33.5%) patients; 91 (47.6%) patients died in their preferred setting, with a kappa value of congruence of 0.016 (95% CI = -0.107, 0.139). Factors associated with congruence were increasing age (odds ratio [OR]: 1.03, 95% CI: 1.00-1.05), use of morphine (OR: 1.87, 95% CI: 1.04-3.36), and wanting to die at home (OR: 0.44, 95% CI: 0.24-0.82). Dying at home was associated with increasing age (OR 1.03, 95% CI 1.00-1.05) and with the patient wishing to have family and/or friends present at death (OR 6.73, 95% CI 2.97-15.30). CONCLUSION: Most patients preferred to die at home, but most died in hospital and fewer than half died in their preferred setting. Further research on modifiable factors, such as effective communication, access to palliative care and morphine, may ensure that more cancer patients in South Africa die wherever they wish.

Informal Caregiver Challenges for Advanced Cancer Patients During End-of-Life Care in Johannesburg, South Africa and Distinctions Based on Place of Death.

CONTEXT: In sub-Saharan Africa, late diagnosis with cancer is common. Many dying patients rely on family members for care; little is known about the challenges African informal caregivers face. OBJECTIVES: To better understand the challenges of informal caregivers at the end of life in South Africa, both at home and in inpatient facilities. METHODS: We included advanced cancer patients and caregivers from a public hospital in Johannesburg, South Africa. Study nurses interviewed patients and caregivers about their experiences. Using univariate and multivariate analyses, we determined the factors associated with greater caregiver difficulty, focusing on patients dying at home vs. in inpatient facilities. RESULTS: Among 174 informal caregivers, 62 (36%) reported "a lot" of challenges. These caregivers struggled most with keeping the patient clean (16%) and with patient interactions (34%). Symptoms associated with greater difficulty included pain (odds ratio [OR] 2.4 [95% CI 1.2-4.7]), urinary incontinence (OR 2.3 [95% CI 1.1-4.9]), fecal incontinence (OR 2.4 [95% CI 1.0-5.7]), insomnia (OR 2.9 [95% CI 1.3-6.9]), fatigue (OR 6.3 [95% CI 1.8-21.6]), extremity weakness (OR 2.9 [95% CI 1.3-6.9]), shame (OR 4.2 [95% CI 1.5-12.0]), and sadness (OR 2.3 [95% CI 1.1-4.8]). Caregivers of patients dying at home reported the greatest difficulty with patients' physical symptoms; caregivers of those dying in facilities reported the greatest difficulty with emotional symptoms. CONCLUSION: Informal caregivers of patients dying at home reported challenges with practical functional care; this effect was reduced in the inpatient setting. Skills training for these caregivers could relieve some of this burden.
