PURPOSE: To assess the prevalence of depression among low-income, ethnic minority women with breast or gynecologic cancer, receipt of antidepressant medications or counseling services, and correlates of depression. PATIENTS AND METHODS: Study patients were 472 women receiving cancer care in an urban public medical center. Women had a primary diagnosis of breast (stage 0 to III) or gynecologic cancer (International Federation of Gynecology and Obstetrics stage 0 to IIIB). A diagnostic depression screen and baseline questionnaire were administered before or during active treatment or during active follow-up. Self-report data were collected on receipt of depression treatment, use of supportive counseling, pain and receipt of pain medication, functional status and well-being, and perceived barriers to cancer care. RESULTS: Twenty-four percent of women reported moderate to severe levels of depressive disorder (30% of breast cancer patients and 17% of gynecologic cancer patients). Only 12% of women meeting criteria for major depression reported currently receiving medications for depression, and only 5% of women reported seeing a counselor or participating in a cancer support group. Neither cancer stage nor treatment status was correlated with depression. Primary diagnosis of breast cancer, younger age, greater functional impairment, poorer social and family well-being, anxiety, comorbid arthritis, and fears about treatment side effects were correlated with depression. CONCLUSION: Findings indicate that depressive disorder among ethnic minority, low-income women with breast or gynecologic cancer is prevalent and is correlated with pain, anxiety, and health-related quality of life. Because these women are unlikely to receive depression treatment or supportive counseling, there is a need for routine screening, evaluation, and treatment in this population.
Major depressive disorder (MDD) and depressive symptoms are prevalent in patients with cancer,1,2 with significant differences in prevalence by site.3 Variable and relatively high rates (up to 48%, depending on the criteria used in assessments) are found among women with breast or gynecologic cancer,4-7 with some evidence that depression can worsen over the course of cancer treatment and persist long after cancer therapy.8 However, the majority of the patients in these studies have been non-Hispanic white and middle- to upper-income women. Less is known about the prevalence of depression among low-income, ethnic minority women with cancer. Correlates of depression among cancer patients include pain, anxiety, poorer functional status, fatigue, quality of life, and survival.9-15 Low-income, ethnic minority patients with cancer also encounter economic and other barriers to cancer care,16-19 and an association between economic stress and depressive symptoms has been found for cancer20 and noncancer patients.21 Oncologists and nurses are found to correctly detect mild to moderate depressive symptoms in only one third of patients with depressive symptoms, to underestimate the level of depressive symptoms among patients who are more severely depressed, and to be most influenced by overt symptoms.22-25 Furthermore, studies find that the majority of depressed patients with cancer who meet diagnostic criteria have not been prescribed antidepressants or are not receiving adequate dosage.26-28 There is also evidence that low-income patients with cancer are less likely to receive mental health services,29 which is evidence that is consistent with numerous primary care studies in which low-income, underinsured, and ethnic minority primary care patients are found to have relatively high rates of depression but are less likely to receive care for depression or to be prescribed antidepressants.30-36 Using baseline data from an ongoing randomized trial of a structured case management intervention to improve adherence to cancer treatment and reduce potential barriers to treatment, of which depression is one probable barrier, we describe the following: (1) the prevalence of depressive disorders, based on results of a valid and reliable diagnostic screen, among low-income, ethnic minority women with breast or gynecologic cancer; (2) correlates of depression, such as pain, anxiety, perceived social support, functional status, and potential barriers to cancer care; and (3) patients' self-reported receipt of antidepressant medications or supportive counseling.
Participants Data on 472 women were drawn from the baseline survey of the National Cancer Institutefunded study Improving Patient Access and Adherence to Cancer Treatment (IMPAACT), which is an ongoing randomized trial of a structured case management intervention to improve adherence to cancer treatment among 500 women with breast or gynecologic cancer. Patients were approached for study participation in outpatient oncology clinics at a large urban public sector medical center. Participants were enrolled onto the study if they were 18 years or older, had a primary diagnosis of breast (stage 0 to III) or gynecologic cancer (International Federation of Gynecology and Obstetrics stage 0 to IVB), and were undergoing active treatment or in active follow-up. Patients were excluded if they were receiving only palliative care or were cognitively impaired to the extent of being unable to participate. Of 621 potentially eligible IMPAACT patients, 500 women (80.5%) were enrolled onto the clinical trial. There were no statistically significant differences between enrolled and nonenrolled patients by age, ethnicity, or cancer stage. Of the 500 women who were enrolled, 250 (50%) were diagnosed with breast cancer, and 250 (50%) were diagnosed with a gynecologic cancer. Of the 250 gynecologic cancer patients, 28 women diagnosed with International Federation of Gynecology and Obstetrics stage IV cancer were excluded from this report to reduce sample stage differences between the two cancer sites. Of the 222 gynecologic patients, 120 women (54%) had cervical cancer, 53 (24%) had uterine cancer, 42 (19%) had ovarian cancer, and seven (3%) had other gynecologic cancer.
Procedures
Measures Demographic and clinical variables. Age, marital status, education, birthplace, primary language, employment, and health insurance status were assessed. Data on personal or household income was not collected given that the study site population is consistent with national and state poverty guidelines. Cancer site, stage, and oncology treatment status at study enrollment were abstracted from medical records. Among women reporting pain, further assessment was made using the Brief Pain Inventory (BPI) Short Form.48,49 A clinically significant cutoff score of 7 or greater indicates severe pain. The reliability and validity of the BPI have been examined for the Spanish version, and it has been used with similar patients at the reported study site.50 The alpha reliability coefficient in this study was .84. Functional status. Functional status was assessed by self-report at baseline using the Karnofsky performance status scale, which is an 11-point rating scale that ranges from normal functioning (100) to death (0).51 The Functional Assessment of Cancer Therapy ScaleGeneral,52 a valid and reliable 27-item health-related quality-of-life questionnaire, assessed physical, functional, social and family, and emotional well-being. The Spanish version (Functional Assessment of Cancer Therapy ScaleSpanish)53 was used with monolingual patients. The alpha reliability coefficients for the subscales in this study were .85 for physical well-being, .81 for functional well-being, .79 for social and family well-being, and .78 for emotional well-being. Mean subscale scores are presented, and cut points of each subscale based on a median score were created for analytic purposes. The presence of six comorbid health conditions (ie, hypertension, heart disease, diabetes, stroke, arthritis, and kidney disease) was obtained from patient self-report. Treatment adherence and perceived barriers to cancer care. Patients were asked a series of questions about the following: completion of treatment to date; number of missed appointments; the reason for missed appointments; whether they were currently taking medication for depression, anxiety, or pain; and whether they had missed taking prescribed medications along with a reason for failure. After a lead statement ("There are different reasons that women may have for not being able to keep scheduled appointments or to follow treatment recommendations. I'm going to name some of these and I'd like you to tell me if any of these problems may be true for you."), a battery of 18 perceived barriers to cancer care were presented. Patients were allowed to choose multiple barriers that included lack of comprehension about treatment recommendations, worries about treatment side effects, economic concerns about cost of care or lost wages, and problems related to personal and family issues or comorbid illness.
Analysis Plan
Demographic, Clinical, and Functional Status Study participants had a mean age of 50.0 years (standard deviation, 11.8 years); were primarily Latina (79%), Spanish speaking (75%), foreign born (88%), and without a partner (59%); and had completed less than 9 years of education (56%). The majority of women (72%) reported receiving Medi-Cal or state and local government financed short-term, episodic assistance in paying for specific types of care (eg, state cancer treatment funds). Of the 472 women, 213 (45%) were employed in the past 12 months; however, the baseline rate of unemployment was high (81%; Table 1).
At enrollment, 38% of patients (n = 178) were newly diagnosed with cancer (35 had recurrent cancers, 7%), 51% (n = 242) were in active cancer treatment, and 11% (n = 52) were receiving active follow-up. Comorbid conditions most frequently cited were hypertension (31%), diabetes (19%), and arthritis (15%). The BPI was completed by 187 women who reported having pain during the past 7 days; 146 of these women (78%) reported taking pain medication. On the BPI scale of 0 to 10, 14% of women rated having pain at a baseline score of 7 to 10. Baseline functional and quality-of-life assessment (Functional Assessment of Cancer Therapy ScaleGeneral) mean subscale scores were 20.9 for physical well-being, 17.9 for social and family well-being, 15.7 for emotional well-being, and 14.3 for functional well-being (Table 2).
Prevalence of Depression Of the 472 study patients, 114 women (24%) met criteria for a MDD. Of the women with MDD, 71 (62%) scored in the moderate range (PHQ-9 score, 10 to 14), 43 (38%) were scored as severe (PHQ-9 score, 15 to 27), and 23 (20%) endorsed suicidal ideation. In addition, 24 of the depressed women (21%) screened positive for anxiety (BSI score, 14 or more). Of the 472 study participants, 70 women (15%) screened positive for dysthymia without major depression (Fig 1).
Adherence and Perceived Barriers to Cancer Treatment Of the 472 study participants, 36 (8%) reported having missed a previous appointment, and 22 (5%) reported having missed taking prescribed medications. Thirty-three women (7%) reported their intention to seek treatment other than that recommended by their physician. And 152 women (32%) reported using complementary and alternative medicine therapies such as teas, herbs, and spiritual healers. Self-reports of perceived barriers to cancer treatment were common among all women, with the majority (70%) reporting four or more barriers. The most commonly cited barriers were concerns about side effects (n = 318, 69%), treatment process (n = 292, 62%), and lack of understanding of what to expect when getting treatment (n = 177, 39%). Economic concerns were also frequent. Patients cited the inability to get all medications (n = 125, 30%), lost wages as a result of sick time (n = 127, 46% of 274 women who responded to questions regarding wage), and/or keeping medical appointments (n = 117, 43%). Personal and family problems were reported as interfering with keeping appointments (n = 132, 28%), as was medical comorbidity (n = 95, 20%). Women reported that they relied primarily on family and friends (52%) and public transportation (31%) to attend their medical appointments.
Correlates of Depression
Barriers to cancer care. Overall, depressed women reported significantly more barriers to cancer care (t = 4.95, df = 470, P < .001), including lack of understanding of treatment recommendations and worries about treatment, side effects, costs, and lost wages. Seven of 18 cancer treatment barriers were significantly related to depression in this sample; these barriers were understanding treatment recommendations (P = .002), fears about receiving treatment (P = .020) and side effects (P = .008), inability to get all prescribed medication (P = .021), concerns about lost wages as a result of illness (P = .002) and as a result of attending medical appointments (P = .010), and forgetting medical appointments (P = .013; Table 3).
Receipt of Depression Care
Logistic Regression Model
Findings indicate that depressive disorder is highly prevalent among the low-income, ethnic minority women in this study and that a majority of women did not receive antidepressant medication or other supportive counseling services. The prevalence of MDD is higher than the prevalence reported in a recent study in which 10% of women in the breast cancer population met diagnostic criteria.56 Furthermore, the percentage of women receiving antidepressant medications is somewhat lower than the 19.2% found by Ashbury et al26 among breast cancer patients in community oncology practices and is in striking contrast to a recent study of predominantly non-Hispanic white, college-educated, middle- to upper-income women with breast cancer in which it was found that, of the 10% of women who met diagnostic criteria for major depression, 80% were receiving antidepressant medication.56 Undertreatment in this study is also consistent with primary care studies, in which Hispanics are found to be less likely than whites to receive depression treatment according to evidence-based guidelines57 and less than half as likely as non-Hispanic whites to receive a diagnosis of depression or antidepressant medication.58 Although this report does not address patient or provider explanations for receipt of care, it is likely that data reflect provider failure to routinely assess and treat depressive disorders that are common across oncology practices28 as well as known barriers to receipt of depression care among low-income populations. In either case, study findings present evidence supporting the utility of routine depression screening59-62 among low-income cancer patients. At the same time, active screening for depression within already burdened and under-resourced public care systems raises additional considerations, including the potential high prevalence of depression symptoms frequently found in low-income and medically underserved populations,63-64 the needs and preferences of culturally diverse patients,65-66 and lack of availability of low-cost depression care in the community.26,67 Despite these considerations, screening can be effective for indigent patients.68 Fortunately, there is also evidence that quality-improvement depression interventions are effective among low-income and ethnic minority primary care patients.69-71 Ethnic minority patients' preference for receiving depression care within the general health sector66 suggests a need to integrate depression care within the oncology care system. Nurses and social workers might be trained to provide depression care for cancer patients.72-73 In a pilot randomized study of 55 depressed, low-income, Latina breast or cervical cancer patients in public sector oncology clinics, onsite depression care management by a medical social worker that included Problem-Solving Therapy (PST)74 and medication follow-up and psychiatric consultation significantly reduced depression symptoms compared with usual care.73 In addition, although the majority of depressed women reporting significant levels of pain were receiving pain medication, a significant number reported limited pain relief. This finding raises questions that are consistent with a previous study of ethnic minority cancer patients in which inadequate pain assessment by physicians (particularly among women), patient reluctance to report pain, and lack of staff time were perceived as barriers to optimal pain management for ethnic minority cancer patients.44 Additional correlates of depression, such as economic worries, less satisfaction with support, and lack of cancer support participation, may be specific to low-income patients with cancer. Lack of participation in cancer support groups may result from both a lack of access and barriers to participation.75 The identification of economic concerns, social support needs, and potential barriers to supportive cancer services suggest the need for supplementary case management services similar to those reported to be effective among impoverished primary care and cancer patients from ethnic minority groups.70 Study limitations include the following: specific diagnostic evaluation of patients' depression was unavailable, the data does not provide conclusive evidence about the causal relationship between identified correlates and depression, and the findings are limited to low-income minority women with cancer receiving care in an urban, public sector setting. In addition, information obtained on functional status, pain, use of medications, social support resources, and barriers to cancer care relied on self-report, although patient self-report of antidepressant use is reasonably accurate.76 However, the collection of longitudinal and medical record data on this cohort of women with cancer is underway. Results from the ongoing randomized intervention study will enable us to examine actual cancer treatment adherence and the effects of the intervention, which includes systems navigation and supportive case management as well as algorithm-guided depression care. Despite limitations, we believe that the study contributes to the existing literature on depression among low-income, minority women with cancer and that, taken together, evidence encourages oncology care providers to consider ways to improve depression care practices and interventions designed for low-income patients. Use of a diagnostic depression screen for these women is likely to identify relatively high rates of clinically significant and undertreated depression. The screen might be used by cancer care providers to aid in targeting women who are likely to benefit from further evaluation, treatment with antidepressant medications, and/or efforts to link these women to mental health specialists and supportive psychosocial care providers within and outside of the oncology care system.
