Purpose To compare supportive care needs between older adults with cancer (age ≥ 65 years) and their younger counterparts. Methods We conducted a retrospective analysis of a prospective cohort of patients with newly diagnosed metastatic solid tumors. Supportive care needs were assessed at baseline and at 3-month follow-up. Patients were divided into two groups (aged ≥ 65/

186 Background: Completion of advance directives can help to ensure consistency with people´s preferences at the end of life. However, disparities in access to advance care planning is common among Hispanic population and little is known about their end-of life wishes. Although in Mexico, advance directives were legalized in 2008, only 21% of people know about it. Objective: To describe end-of-life wishes among patients with advanced cancer planning in a third level hospital in Mexico City. Methods: We conducted a cross-sectional analysis of advance directives planning from patients with advanced cancer included in a multidisciplinary patient navigator-led supportive care program in Mexico City (Te Acompañamos). Patients with a life expectancy of 6 months or less were invited to complete advance directives (AD). Life expectancy was calculated using the palliative performance scale (PPS). Descriptive statistics were used for this analysis. Results: From September 2017 to November 2021, a total of 238 patients were invited to complete AD and 55 (23.1%) completed it, 14.5% in 2017, 29% in 2018, 34.5% in 2019, 9% in 2020 and 12.7% in 2021. The mean age among those who completed AD was 65.8 years (range 38-91), 52.7% were women and 61.8% had gastrointestinal cancer. Forty-three (78.1%) patients stated their wish to die at home, 18.1% to have cardiopulmonary reanimation, 9% invasive mechanical ventilation, 24.4% tube feeding, 90.9% pain medications, 10.9% organ donation, 40% cremation, 38.1% a funeral and 50.9% a death ritual. At median follow up of 5 months (0-39), 43 (78.1%) patients have died, and their endo-of-life wishes were respected in 77.5 % of them concerning the place of death and in 96.7% regarding cardiopulmonary reanimation and invasive mechanical ventilation. Conclusions: In our patient navigator-led supportive program approximately a quarter of patients with advanced cancer and a life expectancy of 6 month or less completed AD and end-of-life wishes were respected in a significant proportion of them. Telemedicine methods used to invite patients during COVID-19 pandemic decreased the proportion of AD completion. Although, advanced care planning is associated with improved in quality of care at the end of life, several barriers and disparities exist among Hispanics and strategies to improve their completion are needed.

181 Background: Caregivers of patients with advanced cancer often face significant physical, social, and emotional distress. In many Latin American cultures, family plays a particularly important role in the decision-making process of patients with cancer, and relatives often assume the role of unpaid caregivers. However, there is limited research about the burden associated with cancer unpaid caregiving among patients living in Latin America. We aimed to describe the profile of caregivers and to identify patient-related factors associated with caregiver burden in a third-level cancer center in Mexico City. Methods: We conducted a cross-sectional analysis of baseline data from patients with advanced cancer and their caregivers included in a multidisciplinary patient navigator-led supportive care program in Mexico City ( Te Acompañamos). At the time of enrollment in the program, caregivers completed a short version of the Zarit Burden scale and patients completed a series of screening questionnaires including assessments of quality of life (FACT-G), depression (PHQ-9), and anxiety (GAD-7). Life expectancy was calculated using the palliative performance scale (PPS). We used descriptive statistics, chi-square tests, and multivariate logistic regression analyses to understand which patient factors were associated with higher caregiver burden. Results: A total of 321 patients with advanced cancer (58% women; average age 63.3 +/- 14 years; 32.7 with hepatopancreatobiliary tumors) and 321 caregivers (67.1% women; 44% were the patient’s son/daughter; 29% were their spouses) were included. Sixty-four caregivers (20%) had a high caregiver burden (score > 16 in the Zarit scale). Caregiver burden was more common among the patients’ spouses (24.1 %) followed by brothers/sisters (23.6%). On univariate analysis, moderate/severe levels of depression (p = 0.001), moderate/severe levels of anxiety (p = 0.02), and lower PPS scores (p = 0.002) were associated with a high caregiver´s burden. Multivariate analysis showed that only PPS < 180 days was associated with increased odds of having caregiver burden (2.0; 95% CI 1.8-3.7); p = 0.02). Conclusions: A significant proportion of unpaid caregivers of Mexican patients with advanced cancer report high levels of caregiver burden, and the odds of having caregiver burden are increased when the patient has a calculated life expectancy of

Background: Early specialized palliative care improves quality of life of patients with advanced cancer, and guidelines encourage its integration into standard oncology care. However, many patients fail to obtain timely palliative/supportive care evaluations, particularly in limited-resource settings. We aimed to determine the proportion of patients with advanced cancer who received an assessment of symptoms and were referred to supportive and palliative care services during the first year after diagnosis in a Mexican hospital. Methods: Individuals with newly diagnosed advanced solid tumors and 1 year of follow-up at the oncology clinics in the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran in Mexico City from October 2015 to April 2016 were included in this retrospective study. Results: Seventy-seven patients were included. Forty-two (54.5%) were referred to the various supportive care services during the first year after diagnosis, and 23 (29.8%) were referred to the palliative care clinic. The most commonly assessed symptoms by oncologists were pain (77.9%), anorexia (74.0%), fatigue (68.8%), and nausea (55.8%), while depression/anxiety were evaluated in 10 (12.9%) patients. The oncologist offered to clarify treatment goals in 39 (50.6%) cases and evaluated the understanding of diagnosis/illness and prognosis in 22 (28.5%). Conclusion: Palliative and supportive care services were widely underutilized, which may be related to a lack of standardized symptom assessments and poor end-of-life communication. Novel strategies are needed to improve the implementation of tools for systematic symptom assessment and to optimize the integration of supportive care interventions into oncology care in developing countries.

e24071 Background: SC includes the prevention and management of the adverse effects of cancer and its treatment. One of the main needs of patients is the mitigation of pain, which is often associated with other symptoms. We studied the presence of pain and its relationship with other symptoms among patients with metastatic cancer enrolled in a SC patient navigation program at a Mexican cancer center. Methods: This was a secondary analysis of a prospective study of adult patients with newly diagnosed metastatic solid tumors at Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán in Mexico City. Patients' SC needs were assessed using validated questionnaires to create a personalized SC plan by a multidisciplinary team. Interventions included pain management, physical therapy, geriatric assessment, psychological support, and nutritional interventions. Descriptive statistics, X2, and Student's T tests were used to compare patients with and without pain. A multivariate model was used to determine the effect of pain and other patient-related factors on the presence of additional SC needs. Results: We included 336 patients with newly diagnosed metastatic solid tumors enrolled in the patient navigation program between 04/2018 and 10/2020 (median age 64 years, range 19-94 years). 46% reported moderate/severe pain, 74% anxiety/depression, 71% fatigue, 37% caregiver collapse, 59% sleep disturbances, 43% required advance directives, 39% had abnormal geriatric evaluation, and 74% risk of malnutrition, with a mean of 4.3 recommended interventions per patient. Patients with pain were more likely to screen positive for anxiety/depression (88 vs. 61%, p < 0.01), to need physical therapy (87 vs. 57%, p < 0.01), to report sleep disturbances (72 vs. 48%, p < 0.01), to have an abnormal geriatric screening (43 vs. 63%, p < 0.1), to require nutritional interventions (84 vs. 65%, p < 0.01), and to have a life expectancy of < 6 months (65 vs. 25%, p < 0.01). The mean number of SC needs for patients reporting pain was 5.8 (95% CI 5.5-6.1) compared to 3.1 (95% CI 2.8-3.4) in those without pain. On multivariate analysis, the presence of moderate/severe pain was associated with increased odds of screening positive for anxiety or depression (OR 3.1, CI 95% 1.62-5.75), and fatigue (OR 2.8, CI 95% 1.49-5.10), while increasing age was found to be inversely associated with the odds of reporting psychological problems (OR 0.9, 95% CI 0.95-0.99). Conclusions: Patients with metastatic solid tumors who report pain require a significantly greater number of interventions and have more additional SC needs, particularly those related to psychological support. These results highlight the importance of multidisciplinary management in patients with advanced cancer, as well as the relevance of collaboration with psychology professionals when providing pain control.

COVID-19 has overwhelmed the capacity of health care systems, limiting access to supportive and palliative care for patients with advanced cancer. Telemedicine has emerged as a tool to provide care continuity to patients while limiting the risk of contagion. However, implementing telemedicine in resource-limited settings is challenging. We report the results of a multidisciplinary patient-navigator-led telemedicine supportive care program in Mexico City. One-hundred sixty-three telemedicine interventions were provided to 45 patients (median age 68, 57% female). A quarter of the patients had less than or equal to elementary school education, and 15% lived in a rural area. The most common interventions were psychological care (33%), pain and symptom control (25%), and nutritional counseling (13%). Half of the interventions were provided by video conferencing. The most common patient-reported barrier was limited experience using communication technology. Our results demonstrate the feasibility of providing supportive and palliative care interventions using telemedicine in resource-limited settings.

Background The early integration of supportive care in oncology improves patient-centered outcomes. However, data are lacking regarding how to achieve this in resource-limited settings. We studied whether patient navigation increased access to multidisciplinary supportive care among Mexican patients with advanced cancer. Materials and Methods This randomized controlled trial was conducted between August 2017 and April 2018 at a public hospital in Mexico City. Patients aged ≥18 years with metastatic tumors ≤6 weeks from diagnosis were randomized (1:1) to a patient navigation intervention or usual care. Patients randomized to patient navigation received personalized supportive care from a navigator and a multidisciplinary team. Patients randomized to usual care obtained supportive care referrals from treating oncologists. The primary outcome was the implementation of supportive care interventions at 12 weeks. Secondary outcomes included advance directive completion, supportive care needs, and quality of life. Results One hundred thirty-four patients were randomized: 67 to patient navigation and 67 to usual care. Supportive care interventions were provided to 74% of patients in the patient navigation arm versus 24% in usual care (difference 0.50, 95% confidence interval [CI] 0.34–0.62; p < .0001). In the patient navigation arm, 48% of eligible patients completed advance directives, compared with 0% in usual care (p < .0001). At 12 weeks, patients randomized to patient navigation had less moderate/severe pain (10% vs. 33%; difference 0.23, 95% CI 0.07–0.38; p = .006), without differences in quality of life between arms. Conclusion Patient navigation improves access to early supportive care, advance care planning, and pain for patients with advanced cancer in resource-limited settings. Implications for Practice The early implementation of supportive care in oncology is recommended by international guidelines, but this might be difficult to achieve in resource-limited settings. This randomized clinical trial including 134 Mexican patients with advanced cancer demonstrates that a multidisciplinary patient navigation intervention can improve the early access to supportive and palliative care interventions, increase advance care planning, and reduce symptoms compared with usual oncologist-guided care alone. These results demonstrate that patient navigation represents a potentially useful solution to achieve the adequate implementation of supportive and palliative care in resource-limited settings globally.

198 Background: Supportive care (SC) in oncology includes the prevention and management of cancer- and treatment-related symptoms and adverse effects. Previous studies have shown that SC needs may differ depending on clinical stage, patients’ gender, comorbidities, and chronological age. The goal of this study was to describe the SC needs of older adults with metastatic cancer enrolled in a SC patient navigation program at Instituto Nacional Ciencias Medicas Salvador Zubiran, an academic, public hospital in Mexico City, and to compare them with those of their younger counterparts. Methods: This was a secondary analysis of a prospective study which included adult patients with newly diagnosed metastatic solid tumors. The patients’ SC needs and symptoms were assessed by a patient navigator using validated questionnaires, and then a multidisciplinary team created a personalized SC plan to address those needs. Potential SC interventions included pain management, physical therapy, geriatric assessment/intervention, mitigation of caregiver burden, depression/anxiety management, and nutritional assessment/intervention. Patients were divided into two age groups (≥65 and < 65 years), and differences in SC needs between groups were compared using Chi square, Student’s T and Mann-Whitney tests. Results: Out of 337 patients with metastatic solid tumors included between April 2018 and October 2020 (median age 64 years, range 19-94 years), 164 (48%) were aged ≥65 years. Among older patients (≥65 years), 130 (79%) had an abnormal geriatric screening and were referred for a comprehensive geriatric assessment. Older adults were more likely than younger patients to report malnutrition needing nutritional assessment/intervention (81 vs. 65%, p < 0.01) and to experience fatigue needing a referral to physical therapy (77 vs. 66%, p = 0.03). We found no differences in moderate/severe pain (45 vs 47%, p = 0.79), depression/anxiety (69 vs 77%, p = 0.09), caregiver burden (42 vs 34%, p = 0.12) or sleep disturbances (54 vs 64%, p = 0.07) between groups. However, the total number of SC needs was significantly higher for older adults than for their younger counterparts (4.9 vs. 3.9, p < 0.01). Conclusions: The results of this study show that older adults with metastatic solid tumors have more SC needs and require more symptom management interventions than their younger counterparts. The need for nutritional interventions and physical therapy was significantly higher among older patients, thus, these components should be considered an essential part of geriatric oncology multidisciplinary programs. Oncologists treating older adults with advanced cancer should screen for SC needs among older patients in order to provide targeted interventions.

12112 Background: We previously reported improvements in access to SC, advance directive completion, and pain control in a RCT comparing a patient navigator-led early SC intervention vs. usual care among patients with newly-diagnosed metastatic cancer in Mexico (NCT03293849). We now present results on healthcare utilization and OS. Methods: Patients were randomized to PN or usual oncology care. Patients in the PN arm received SC interventions by a navigator-led multidisciplinary team (palliative care, physical therapy, geriatrics, psychology) in the first 12 weeks after diagnosis. At 12-weeks, patients allocated to usual care were able to cross-over to PN and receive multidisciplinary SC. We analyzed the number (no.) of emergency room (ER) visits, their cause, and whether they were potentially avoidable (as determined by expert consensus), using descriptive statistics and X2 tests. OS was estimated using the Kaplan-Meier method and the log-rank test. Results: 133 patients (median age 60, range 23-93; 52% male) were randomized (66 PN, 67 control) from 08/17 to 04/18. Median follow-up was 22.8 months. 61% had gastrointestinal tumors, and 45% had a calculated life expectancy ≤6 months. 69% of patients randomized to usual care crossed-over to PN and received SC interventions. 80% of patients attended the ER ≥once (median no. of visits = 2). No difference was found between patients randomized to early SC or usual care in ER visits (2.4 vs. 2.3, p = 0.58). Out of a total 316 ER visits, the most common reason was infections (n = 69, 22%), followed by pain (n = 40, 13%), and indwelling catheter-related complications (n = 23, 7%). 41% of ER visits were considered as potentially avoidable, with no difference in avoidable visits found between arms (1.7 vs. 1.7, p = 0.49). No differences between arms were found in no. of hospitalizations (0.8 vs. 0.6 p = 0.82). Survival results were assessed after 64% of patients had died (n = 85), finding no statistically significant OS difference between the early SC intervention and the usual care arms (11.0 vs 13.0 months, p = 0.77) Conclusions: In the context of a limited-resource healthcare system, the early delivery of SC did not improve healthcare utilization, reduce avoidable ER visits, or prolong OS compared to the implementation of SC at a later time, which might be partially explained by the unavailability of hospice or home care, and by high rates of cross-over between arms.

Background Interventions aimed at improving access to timely cancer care for patients in low- and middle-income countries (LMIC) are urgently needed. We aimed to evaluate a patient navigation (PN) program to reduce referral time to cancer centers for underserved patients with a suspicion or diagnosis of cancer at a public general hospital in Mexico City. Materials and Methods From January 2016 to March 2017, consecutive patients aged >18 years with a suspicion or diagnosis of cancer seen at Ajusco Medio General Hospital in Mexico City who required referral to a specialized center for diagnosis or treatment were enrolled. A patient navigator assisted patients with scheduling, completing paperwork, obtaining results in a timely manner, transportation, and addressing other barriers to care. The primary outcome was the proportion of patients who obtained a specialized consultation at a cancer center within the first 3 months after enrollment. Results Seventy patients (median age 54, range 19–85) participated in this study. Ninety-six percent (n = 67) identified >1 barrier to cancer care access. The most commonly reported barriers to health care access were financial burden (n = 50) and fear (n = 37). Median time to referral was 7 days (range 0–49), and time to specialist appointment was 27 days (range 1–97). Ninety-one percent of patients successfully obtained appointments at cancer centers in Conclusion Implementing PN in LMIC is feasible, and may lead to shortened referral times for specialized cancer care by helping overcome barriers to health care access among underserved patients. Implications for Practice A patient navigation program for patients with suspicion or diagnosis of cancer in a second-level hospital was feasible and acceptable. It reduced patient-reported barriers, and referral time to specialized appointments and treatment initiation were within international recommended limits. Patient navigation may improve access to care for underserved patients in developing countries.

11505 Background: Early integration of SC to the treatment of advanced cancer can improve outcomes, but this may be challenging in developing countries due to a lack of resources and knowledge. In this RCT, we examined whether PN could improve early access to SC among Mexican patients with metastatic solid tumors as recommended by ASCO guidelines. Methods: Adult patients with newly-diagnosed metastatic cancer were randomly assigned to PN or standard oncologic care. At baseline, a navigator assessed the patients’ SC needs (depression, anxiety, fatigue, pain, caregiver burden) using validated questionnaires administered with an electronic tablet. For those in the PN arm, a personalized SC plan was created and implemented by a multidisciplinary team (palliative care, physical therapy, geriatrics, psychology, psychiatry). The primary outcome was access to SC, defined as receipt of SC interventions in the first 3 months (mo) after diagnosis. Secondary outcomes included advanced directive (AD) completion (for patients with expected survival ≤6 mo in accordance to Mexican law), changes in SC needs, and changes in quality of life (assessed using FACT-G). Results: 133 patients (median age 60, range 23-93; 52% male) were randomized (66 PN, 67 control). 61% of patients had gastrointestinal tumors. 94% of patients in the PN arm completed baseline assessments and received recommendations from the navigator. At 3 mo, 37 patients died or were lost to follow-up (16 PN, 21 control; p = 0.45), and 96 completed assessments. SC interventions were provided to 73% of patients in the PN arm and 24% of controls (p < 0.01). In the PN arm, 48% of 29 eligible patients completed AD, compared to 0% of eligible controls (p < 0.01). At 3 mo, patients in the PN arm were significantly less likely to report moderate/severe pain than controls (10 vs 33%, p = 0.006). There were no significant differences in other symptoms or in FACT-G scores (76 vs 76.3, p = 0.46) between PN and control arms at 3 mo. Conclusions: PN can lead to significant improvements in early access to SC, AD completion, and pain control among patients with metastatic cancer treated in a resource-limited setting. Clinical trial information: NCT03293849.

124 Background: Although referral to supportive care (SC) services improves quality of life in patients with cancer, several barriers can hamper access to SC, particularly in developing countries with limited resources. We studied patient-reported barriers for accessing SC in a cancer center in Mexico City, and factors associated with those barriers. Methods: Patients with metastatic cancer enrolled in a randomized clinical trial of patient navigation to improve access to SC in a public cancer center in Mexico City (NCT03293849) were included. At baseline, sociodemographic and clinical characteristics were collected, and patients answered a survey in which they reported barriers to obtain cancer treatment and SC. We analyzed the frequency of reported barriers using descriptive statistics, and explored if sociodemographic factors were associated with a higher likelihood of reporting any barrier. Results: 134 patients were included between 08/17 and 04/18. Median age was 60 years (range 23-93; 51.5% male); 89.5% lived in urban areas; 42.5% had less than high school education; 12% had formal employment; and 27.3% had no insurance coverage. 61% had gastrointestinal, 16 % genitourinary, and 23 % other tumors. Home-to-hospital time was < 2 hours (h) in 60%, 2-6 h in 27%, and ≥6 h in 13%. 47.7% of the patients reported a household income of less than 630 USD/month. The mean number of reported barriers was 1.96 (Standard Deviation 1.77). 78% identified at least one barrier to care, and 35% reported ≥3 barriers (range 1-8). The most commonly reported barriers were: financial burden (47%), beliefs about treatment (28%), lack of transportation (22%), fear (19%), home-to-hospital distance (16%), patient-provider communication (13%), employment (9%), and caregiving for other people (3%). Patients living in rural areas more often reported home-to-hospital distance as a barrier than those living in urban areas (69 vs 11%, p < .01). Conclusions: Most patients with metastatic cancer seen at a cancer center in Mexico identified at least one barrier to cancer care, with some reporting up to 8. Many of the reported barriers are potentially modifiable through patient navigation or SC interventions.

42 Background: Patient awareness regarding diagnosis and prognosis may lead to improved treatment shared decision making and improve satisfaction with treatment choices. We assessed the diagnostic and prognostic awareness among newly diagnosed patients with metastatic solid tumors in a public cancer center in Mexico City. Methods: Patients with metastatic cancer enrolled in a randomized clinical trial of patient navigation to improve access to supportive care in a public cancer center in Mexico City (NCT03293849) were included. At baseline, demographic, social, and clinical characteristics were collected. Patients answered open-ended questions regarding knowledge about their diagnosis and prognosis, as well as on patient-physician communication. We analyzed prognostic and diagnostic awareness using descriptive statistics, and explored if patients reporting worse patient-physician communication were less aware of their diagnosis and prognosis. Results: 125 patients were included between 08/17 and 04/18. Median age was 61 years (range 23-93; 52% male); 88.8% lived in urban areas; 41.6% had less than high school education; and 57.6% were married or partnered. 61% had gastrointestinal, 14% genitourinary, and 25% other tumors. Although all patients had had at least one consultation with an oncologist, 3% did not know what their diagnosis was. 77% of patients considered they had prognostic awareness; however, only 14% considered that their disease had a bad prognosis, and 2% considered they could be cured. 6.5% of the patients believed the information given by their oncologist was insufficient, and 8% felt they had trouble getting information about their disease. We found no statistically significant relationship between perceived barriers to patient-physician communication and diagnostic (p = 0.28) or prognostic (p = 0.18) awareness. Conclusions: Although most patients understood their oncologic diagnosis, a significant proportion were unaware of their prognosis. Communication strategies, tailored to the specific characteristics of each patient population and aimed at improving prognostic awareness, are fundamental for optimal shared decision making.

6544 Background: High cancer mortality rates in developing nations are partially driven by advanced stages at diagnosis and limited access to care. In Mexico, the interval from problem identification to start of treatment can be up to 7 months, mostly due to healthcare system delays. We implemented a patient navigation (PN) program aimed at reducing time to referral to cancer centers for patients (pts) with a suspicion or a diagnosis of cancer seen at a public general hospital in Mexico City. Methods: Pts age > 18 seen at Hospital General Ajusco Medio in Mexico City who required referral to a cancer center were enrolled. Baseline demographic, economic and psychosocial data were collected. A Patient Navigator assisted pts with scheduling; paperwork; obtaining results in a timely manner; transportation; and with other cultural barriers. The goal of the PN program was for at least 70% of enrolled patients to obtain a specialized appointment at a cancer center within the first 3 months from enrollment. Results: 53 pts (median age 54, range 19-80; 51% female) were included between 01/16 and 12/16. 19% (n = 10) had breast/GYN, 19% (n = 10) GU, 19% (n = 10) endocrine, 19% GI (n = 10) and 14% (n = 13) other tumors. All the pts were uninsured, 59% (n = 30) had less than middle school education, 80% (n = 41) were unemployed and 96% (n = 49) had a monthly household income of < $360 USD. 54% (n = 28) reported deprivation in at least one basic living need (education, running water, toilet, electricity or flooring). The most commonly identified barriers to healthcare access were financial (73%, N = 37), lack of transportation (47%, N = 24), fear (37%, N = 19) and poor communication with healthcare workers (35%, N = 18). Mean time to referral was 11 days (range 0–46, SD 11.2) and mean time to cancer specialist appointment 26 days (range 1–94, SD 21.18). 92% of pts successfully obtained appointments at a cancer center in < 3 months. Conclusions: Compared with previously reported data, this PN program shortened time to referral to a cancer center for pts with a suspicion or diagnosis of cancer in Mexico City. PN represents a potential solution to overcome barriers to healthcare access for underserved pts with cancer in developing countries.
