Abstract: Objective  To develop a health comprehensive evaluation scale for elder population seeking medical advice or care in medical institutions of Beijing and test the reliability and validity.  Method  To put together an initial scale through literature review, expert seminar and Delphi expert consultations. There were 60 elderly patients selected to participate the pre-experiment to and the initial scale improved. Total of 461 elderly patients were analyzed in the preliminary testing of validity and reliability and item discrimination, correlation analysis, exploratory factor analysis and internal consistency check was conducted for items screening. Total of  347 elderly patients were recruited in the second testing, and test-retest reliability, rater consistence reliability and predictive validity was conducted. Result  There were 5 dimensions (clinical complexity;medication treatment; diet, nutrition, and lifestyle; signs and symptoms;functional status) and  26 items contained in the formal scale. For the whole scale the split-half reliability was 0.631, and the Cronbach's α coefficient was 0.665, and the test-retest reliability was 0.739, and the rater consistence reliability was 0.747. There was significant correlation between score of the scale and common blood tests index (albumin, hemoglobin), physical examination index (body mess index, grip strength, calf circumference), nutritional screening scale, and hospitalization duration.Conclusions  The preliminary work was finished by developing a health comprehensive evaluation scale with acceptable reliability and validity, which was suitable for elder population seeking medical advice or care in medical institutions of Beijing.
