Prior Status Going Away

Homecare Insider, January 26, 2009

Some of the most challenging questions in the current OASIS data set deal with the patent’s prior status.  Every data element on activities of daily living (ADL) and instrumental activities of daily living (IADL) asks about the patient’s status 14 days prior to the start or resumption of care or the recertification date.  Using an arbitrary date provides little or no insight into the patient’s actual status before the illness or injury.  Example:  The patient is receiving homecare services after surgery for a broken hip.  Fourteen days prior to the start of care, he could have been on the operating room table. 

OASIS-C is the first major revision of the OASIS data set, on track for implementation in 2010.  This revised data set will eliminate prior status and incorporate four new data elements asking about the patient’s ability prior to the onset of the illness or injury.  These data elements are:
• M1880, change in mobility:  “Is the patient’s ability to transfer and/or ambulate safely better, the same, or worse than prior level of functioning (i.e., before the onset of the illness or injury that initiated this episode of care)?”
• M1890, change in self-care ability:  “Is the patient’s ability to perform self-care activities safely (grooming, dressing, and bathing) better, the same, or worse than prior level of functioning (i.e., before the onset of the illness or injury that initiated this episode of care)?”
• M1920, change in ability to perform routine household tasks:  “Is the patient’s ability to perform routine household tasks safely (light housekeeping, light meal preparation, laundry) better, the same, or worse than prior level of functioning (i.e., before the onset of the illness or injury that initiated this episode of care)?”
• M2040, change in ability to manage oral, inhalant, or injectable medications:  “Is the patient’s ability to prepare and take all prescribed medications (oral and, if applicable, inhalant or injectable medications) reliably and safely (including administration of the correct dosage at the appropriate times/intervals) better or worse than before the onset of the illness or injury that initiated this episode of care?”
