AB  - BACKGROUND: Existing instruments for measuring mobility are inadequate for 
      accurately assessing older people across the broad spectrum of abilities. Like 
      other indices that monitor critical aspects of health such as blood pressure 
      tests, a mobility test for all older acute medical patients provides essential 
      health data. We have developed and validated an instrument that captures 
      essential information about the mobility status of older acute medical patients. 
      METHODS: Items suitable for a new mobility instrument were generated from 
      existing scales, patient interviews and focus groups with experts. 51 items were 
      pilot tested on older acute medical inpatients. An interval-level unidimensional 
      mobility measure was constructed using Rasch analysis. The final item set 
      required minimal equipment and was quick and simple to administer. The de Morton 
      Mobility Index (DEMMI) was validated on an independent sample of older acute 
      medical inpatients and its clinimetric properties confirmed. RESULTS: The DEMMI 
      is a 15 item unidimensional measure of mobility. Reliability (MDC(90)), validity 
      and the minimally clinically important difference (MCID) of the DEMMI were 
      consistent across independent samples. The MDC(90) and MCID were 9 and 10 points 
      respectively (on the 100 point Rasch converted interval DEMMI scale). CONCLUSION: 
      The DEMMI provides clinicians and researchers with a valid interval-level method 
      for accurately measuring and monitoring mobility levels of older acute medical 
      patients. DEMMI validation studies are underway in other clinical settings and in 
      the community. Given the ageing population and the importance of mobility for 
      health and community participation, there has never been a greater need for this 
      instrument.
