title: Clinical factors associated with prescription of a prosthetic limb in elderly veterans.
abstract: OBJECTIVE
  To determine how advanced age influences prosthetic prescription.
  
  
  METHODS
  Retrospective cohort analysis with theory-driven logistic regression models. A Post Amputation Quality-of-Life (PAQ) framework of outcomes was proposed and empirically tested.
  
  
  METHODS
  Veterans Affairs Medical Centers.
  
  
  METHODS
  Two thousand three hundred seventy-five veterans with lower extremity amputations discharged between October 1, 2002, and September 30, 2003.
  
  
  METHODS
  Prosthetic prescription within 1 year of amputation.
  
  
  RESULTS
  Patients younger than 76 were 4.5 times as likely to receive a prescription compared to those aged 86 and older (odds ratio=4.51, 95% confidence interval=1.36-14.99) after controlling for sex, marital status, living circumstance before hospitalization, anatomical level, etiologies, comorbidities, medical acuity, and initial functional status. Patients admitted from extended care and patients with peripheral vascular disease, systemic sepsis, renal failure, congestive heart failure, psychoses, metastatic cancer, paralysis, or other neurological disorders were less likely to receive a prescription, as were patients who underwent procedures for acute central nervous system disorders, severe renal disease, or serious nutritional compromise. Veterans evaluated initially as more cognitively and physically able had higher likelihood of prosthetic prescription, and those with transtibial amputations had higher likelihood of prosthetic prescription than those with transfemoral amputations.
  
  
  CONCLUSIONS
  Amputees aged 75 and older are less likely to receive a prosthetic limb prescription than younger individuals, even after controlling for comorbidities and functional status. Findings support the PAQ framework, in which contexts, etiologies, anatomic level, comorbidities, medical acuity, and initial function are determinants of outcome. Medical and functional conditions that adversely affect level of energy, ability to move independently, or ability to exercise judgment reduce the likelihood of prosthetic prescription.
