title: Chiropractic care for patients aged 55 years and older: report from a practice-based research program.
abstract: OBJECTIVE
  To characterize patients aged 55 years and older and features of chiropractic care provided to them.
  
  
  METHODS
  Observational, practice-based research study.
  
  
  METHODS
  Chiropractic offices in the United States and Canada, 1997-1998.
  
  
  METHODS
  Chiropractors in 96 practices in 32 states and two Canadian provinces collected data on 805 eligible patients aged 55 years and older during a 12-week study period.
  
  
  METHODS
  In addition to questionnaires on practice characteristics, patient demographics, chief complaints, and health habits, two standardized instruments were administered: for general health status, the Medical Outcomes Study 12-Item Short-Form Health Survey (SF-12); and for disability related to chronic pain, the Pain Disability Index (PDI).
  
  
  RESULTS
  Of 805 study patients, 60.1% were women and' 94.7% were white. Overweight patients comprised 38.6% and obese 20.6% (n = 656) of the total; 9.7% of patients were hypertensive (n = 590). Smoking was reported by 12.7% and 50.2% reported regular exercise. The Physical Component Summary scores of the SF-12 seemed somewhat lower than population norms, whereas the Mental Component Summary scores differed very little from norms. Chief complaints were predominantly pain-related (72.3%), most commonly back pain (32.9%). The PDI mean baseline score for chronic patients was 16.3 (scale, 0-70), and 40.6% of study patients reported using at least one pain medication (prescription or nonprescription) more than three times per week. More than half of complaints (54.9%) had onsets more than 6 weeks before the baseline visit. For 66.6% of subjects, a chiropractor was the only provider for their current complaint. In addition to manipulation, most common features of care were recommendations on exercise (41.0%), heat or cold applications (40.8%), and food supplements (24.5%). At 4 weeks, 19.6% were discharged, 58.8% continued treatment, and 20.1% had discontinued care (self-discharged). For these three groups, those with higher PDI mean baseline scores showed more change at 4 weeks. For patients who were discharged by the doctor, the proportion of reported pain medication use decreased 7.3% from baseline to 4 weeks, increased for patients who discontinued care, and remained about the same for those continuing care.
  
  
  CONCLUSIONS
  Further investigation of the PDI and a decrease in pain medication use as outcome measures seems warranted. The descriptive information in this study may assist providers of care to older adults to better understand their patients' use of chiropractic care.
