title: The impact of pain control on physical and psychiatric functions of cancer patients: a nation-wide survey in Taiwan.
abstract: OBJECTIVE
  To investigate the prevalence of pain in cancer patients at different disease statuses, the impact of pain on physical and psychiatric functions of patients and the satisfaction of pain control of patients at outpatient clinic department in Taiwan.
  
  
  METHODS
  Short form of the Brief Pain Inventory was used as the outcome questionnaire. Unselected patients of different cancers and different disease statuses at outpatient clinic department were included. The impacts of their current pain control on physical function, psychiatric function and the satisfaction of doctors were evaluated. Logistic regression analyses were performed to evaluate whether the interference scale performed identically in the different analgesic ladders. The dependent variables were satisfaction toward physician and treatment.
  
  
  RESULTS
  A total of 14 sites enrolled 2075 patients in the study. One thousand and fifty-one patients reported pain within the last 1 week. In patients whose diseases deteriorated, >60% of them need analgesics for pain control. Pain influenced physical and psychiatric functions of patients, especially in the deteriorated status. More than 80% of patients were satisfied about current pain control, satisfaction rate related to disease status, pain intensities and treatments for pain.
  
  
  CONCLUSIONS
  Our study found that different cancers at different statuses had pain at variable severity. Pain can influence physical and psychological functions significantly. More than 75% of subjects reported satisfaction over physician and pain management in outpatient clinic department patients with cancer pain in Taiwan.
