BackgroundPain in cancer patients is recognized as a major health problem, yet few studies of both inpatient and outpatient populations have been carried out.ObjectiveThe study objective was to assess the frequency, type, and characteristics of pain in adult cancer patients, including both inpatients and outpatients.MethodsThis cross-sectional study involved 1064 adult cancer patients (437 outpatients and 627 inpatients) from 44 hospitals and/or long-term-care centers in Catalonia, Spain. Cancer patients suffering from pain of any etiology for ≥2 weeks and/or under analgesic treatment ≥2 weeks were enrolled. Demographic and pain data were collected. The Spanish version of the Brief Pain Inventory was used to assess pain.ResultsPain frequency was 55.3%. Pain was less frequent in outpatients than inpatients (41.6% versus 64.7%; p<0.001), although median pain duration was longer in outpatients (20 versus 6 weeks; p<0.001). Pain was assessable in 333 patients, and intensity was similar in both out- and inpatients; however, outpatients reported less improvement, less pain interference with daily life, and less pain related to the cancer per se. In both groups, patients with multiple myeloma (73%), breast (65%), and lung cancer (61%) were most likely to report pain.ConclusionsPain in cancer patients, both ambulatory and hospitalized, remains a challenge for health care professionals, health administrators, and stakeholders. Our study reveals the high level of pain and distress that cancer patients continue to suffer, a problem that is particularly notable in outpatients due to the intensity and duration of the pain.
