Background: Social determinants of health (SDOH) have a considerable impact on the health outcomes of chronically ill patients. Although the implementation of social needs screening in clinical settings has been studied, patient perspectives of discussing SDOH with health care providers has not been thoroughly investigated. This study sought to explore the experience and perspectives of limited-resource patients with cancer regarding SDOH discussions. Methods: This cross-sectional analysis used data from a nationwide survey distributed in May 2022 by Patient Advocate Foundation (PAF). The survey was fielded via email to patients who received PAF services in 2020. Inclusion criteria included a valid email, aged >19 and a current or previous cancer treatment. Frequencies and percentages were calculated for categorical variables. Questions focused on individual experiences with SDOH screening, conversations and expectation around information use and assistance. Results: A total of 481 survey respondents with cancer completed the survey. Most respondents were female (73%), aged 56-75 (52%), household income < $48,000 (66%), and insured (98%); 38% were Black, Indigenous or Persons of Color (BIPOC). The most common cancer types were hematologic (42%) and breast (34%); 30% were diagnosed < 2 years prior and 82% received treatment in past 6 months. One quarter (26%) stopped or delayed care in past 12 months due to cost and 66% reported that social needs interfered with treatment in past 12 months. Two-thirds (64%) reported conversations about social needs in the past 12 months. Transportation (36%), food insecurity (32%) and personal safety were the most cited nonmedical needs. Conversations were most often initiated by nurse/PA (30%), social worker (30%) or doctor (29%) and patients reported being ‘extremely comfortable’ being asked these questions by the same providers; doctor (54%), nurse/PA (48%), social worker (46%). Over half (53%) reported comfort with SDOH information being part of their medical record; 61% wanted to be asked SDOH questions face-to-face. If a social need was identified, patients trusted patient advocacy groups (64%), social worker (61%) and charitable non-profit organizations (49%) to help them locate assistance. Only 21% indicated knowledge of availability of needs navigation services. Conclusions: Although patients are open to sharing social issues with providers, our data suggests that conversations may not be routinely initiated in clinical settings. There is also a need to increase awareness of resources in response to SDOH screening. Challenges in trust and privacy persist when disclosing this information. Achieving health equity requires culturally responsive strategies to embed screening and referrals into workflow to ensure cancer patients’ needs are identified and they are linked to appropriate nonmedical resources and services.
