Since the 1970s, investigations of cancer-related psychological distress have consistently reported prevalence rates ranging between 20% and 40%.1–6 Distress, as defined by NCCN, is “a multifactorial unpleasant emotional experience of a psychological…social, and/or spiritual nature that may interfere with the ability to cope effectively with cancer, its physical symptoms, and its treatment.”7 Distress is not a diagnosable disorder. Like fever or high blood pressure, distress is an indicator—a psychosocial marker—of conditions requiring further clinical evaluation and response, including redress of the distress itself. Elevated distress may suggest that depression or anxiety are present at clinically significant levels, or that a patient is struggling with co-occurring physical, psychological, social, or spiritual-existential challenges that are likely to disrupt adherence to therapy.8
Distressed patients tend to experience poorer health outcomes, greater mortality and morbidity, poorer immune function, and greater healthcare expenditures.9 Distress also contributes to greater service use.10–12 In 2007, the Institute of Medicine (now Health and Medicine Division, National Academies of Sciences, Engineering, and Medicine) identified critical shortcomings in the delivery of psychosocial care for patients with cancer and their families, particularly with regard to the detection of psychological distress.13 In response, the American College of Surgeons' Commission on Cancer (CoC), the primary accrediting body for as many as 1,500 cancer-treating programs serving approximately 70% of US patients with cancer, established new accreditation standards for patient-centered care, including Standard 3.2, a mandate requiring that all patients be screened for distress and that there be an appropriate clinical response when patients are identified as distressed.14
Evidence of the effect of distress screening on patient and institutional outcomes is mixed and underdeveloped. Some studies suggest that screening results in reductions in emotional distress, better quality of life, and improved patient–provider communication, along with increases in appropriate referral to psychosocial care providers.15,16 Others suggest that screening patients for distress may be of minimal benefit.17,18 Lacking, however, are studies demonstrating the effect of both screening and appropriate clinical response on patient and institutional outcomes.19,20 Just as we do not expect blood pressure screening alone to reduce symptoms of cardiovascular disease or stroke, we should not expect distress screening alone to improve outcomes.12 There must also be an appropriate clinical response when risk conditions are detected, because patient outcomes are improved after receipt of evidence-based psychosocial support interventions.21–25
Although now required as a component of quality psychosocial care, the CoC's distress screening standard does not prescribe a screening instrument nor dictate when or how often screening is to occur, other than at a “pivotal visit.” The standard also does not dictate how providers must respond to distressed patients. Cancer programs determine their own protocols for clinical response (eg, immediate contact with a social worker, referral to supportive care services). Thus, given that individual cancer programs vary in their algorithms and pathways for how and when they screen for distress and respond to patients, the primary purpose of this study was to examine the capacity of individual cancer programs to adhere to their own prescribed distress screening protocols. It also examined the extent to which protocol adherence was associated with subsequent medical service utilization, specifically rates of emergency department (ED) use and hospitalization. We hypothesized that higher rates of service utilization would be associated with lower rates of adherence to screening protocols, after controlling for select patient and institutional factors.
