title: Impact of painful physical symptoms on depression outcomes in elderly Asian patients.
abstract: BACKGROUND
  Painful physical symptoms (PPS) are prevalent among elderly patients with depression. We describe the impact of PPS on depression outcomes and quality of life (QOL) of elderly Asian patients with major depressive disorder (MDD).
  
  
  METHODS
  Thispost hocanalysis of data from a three-month prospective observational study of East Asian MDD in- or out-patients focused on elderly patients aged ≥60 years. Depression severity was evaluated using the Hamilton depression (HAMD-17) and clinical global impression of severity (CGI-S) scales, while QOL was measured using EuroQOL (EQ-5D and EQ-VAS) instruments. PPS were rated using the modified somatic symptom inventory (SSI).
  
  
  RESULTS
  At baseline, depression was moderate to severe and 49% of the 146 elderly patients were painful physical symptom positive (PPS+). Bivariate analysis showed significant correlations between PPS and depression severity and QOL at baseline. Linear regression models showed the baseline factor most significantly associated with depression severity at three months was baseline PPS status. PPS+ patients had a mean increase of 2.87 points in their HAMD-17 rating and 0.77 points in their CGI-S score. Response and remission were significantly lower in PPS+ patients; response was 60% and remission was 40% in PPS+ patients while 82% and 66% in painful physical symptom negative (PPS-) patients. QOL at endpoint was lower in PPS+ patients.
  
  
  CONCLUSIONS
  PPS are common in elderly Asian patients with MDD and negatively influence depression outcomes and QOL. Patients with PPS had lower QOL at baseline, lower response and remission rates, higher severity of depression, and lower QOL after three months of treatment.
