The protocol is not appropriate in all situations 
Our protocol was designed for patients who have been hospitalized for an acute medical problem. However, other tools, such as the Barthel Index, should be used in rehabilitation centers. The original Katz ADL scale scores functional ability only on a 7-point scale (scores of 0&#8211;6); subtle fluctuations in functional dependence may therefore be overlooked. The Barthel Index, which is generally comparable to the Katz ADL, yields weighted and summe...

Medical problems can cause older people to lose functional independence, rendering them unable to carry out activities of daily living (ADL) without assistance from others. This loss of independence, which often results from cardiovascular comorbidities1, cognitive impairment2,3, and visual impairment4, impacts patient quality of life5 and life expectancy6, and increases healthcare costs7. Functional independence may progressively deteriorate, or be lost completely, with more severe comorbidities (cognitive impairment, heart failure, etc.). It may also worsen during an acute medical problem, such as stroke, myocardial infarction, lower limb fracture, or chest infection8. About 30% of patients aged between 70 and 80 years, and 60% of those aged over 80 years, experience such a loss of independence during hospitalization9,10. Patients may recover the functional independence they enjoyed prior to the acute medical problem, or it may persist thereafter despite appropriate treatment.
It is widely accepted that treatment aimed at maintaining or restoring functional independence during hospitalization for an acute medical problem is most effective if it is started as soon as possible11. Physical exercise during hospitalization improves function in the short and medium term12,13. In a hospitalized population, scores on measures of ADL were associated with muscle oxidative capacity and muscle function1. Hence, assessing a patient&#39;s functional independence at an early stage of hospitalization is a priority; this assessment should then be compared with the patient&#39;s level of ADL independence before hospitalization (baseline). Medical care, particularly nursing care, is aimed at restoring any loss of independence or maintaining the existing level thereof. This requires a reliable and reproducible assessment method; the most commonly used measure for this purpose is the Katz Index of Independence in Activities of Daily Living (Katz ADL).
The Katz ADL, developed in 1970, allows assessment of a patient&#8217;s ability to carry out basic ADL independently15,16. The scale measures patient independence in six activities: bathing, dressing, toileting, transferring, continence, and feeding. Each activity is scored as 0 or 1, where a score of 0 indicates dependence on another person, and 1 indicates independence. A total Katz ADL score of 6 denotes full independence, a score of 4 moderate dependence, and a score of 2 or less severe dependence.
For many years, the Katz ADL has proven useful in the assessment of functional status in older people. First, the Katz ADL assessment is very simple to perform and involves interviewing the patient or family members about the patient&#8217;s ability to perform the six ADL activities, or directly observing how well the patient performs these activities17. Furthermore, during an acute medical problem, the Katz ADL Index is sensitive to major, but not to minor, changes in health status. Thus, this tool is ideal for assessing the impact of an acute medical problem on patients&#8217; functional status, whatever their chronic morbidities.
When initiating rehabilitation within the first days of an acute medical problem, it is necessary to determine the extent of the patient&#8217;s functional decline. For this purpose, we propose that the functional status of each patient should be assessed before hospitalization via interview, and that the ability to perform ADL be assessed within the first days of hospitalization via observation. These two assessments could guide early preventive and rehabilitative measures in parallel with a care plan for the acute event. The effectiveness of these measures for promoting recovery of functional independence can be monitored by repeated ADL assessment until discharge.

assessment of dependence in activities of daily living among older patients in an acute care unit

During an acute medical problem, older people may lose functional independence. ADL scales are used to assess this loss of independence. The simplest and most convenient ADL scale is the Katz Index, which measures six ADL: bathing, dressing, toileting, transferring, continence, and feeding. A lower ADL score indicates greater loss of functional independence. The ADL score prior to the acute medical problem (baseline) is estimated by questioning the patient or the caregivers, and this score is then compared with that on hospital admission. The ADL score should be monitored from hospital admission until discharge to allow early detection of changes in functional independence. Identifying any loss of functional independence before and during hospitalization provides information to caregivers regarding the risk of short-term mortality risk and complications, and the prognosis after hospitalization.

Here, we consider two example cases after completion of the protocol: one with full recovery of the baseline level of ADL function at discharge, and one with no or partial recovery.
Discharged with baseline level of ADL function 
In this group of patients, two ADL function trajectories were possible, as shown in Figure 1: patients who maintained their ADL score throughout hospitalization (Trajectory A) and those whose score at hospitalization...

Assessment of Dependence in Activities of Daily Living Among Older Patients in an Acute Care Unit

During acute medical problems, older people may lose independence in activities of daily living (ADL). Assessment of baseline ADL and ADL on admission can guide personalized treatment plans aimed at preventing nosocomial dependence and ensuring better functional outcomes.

During an acute medical problem, older people may lose functional independence. ADL scales are used to assess this loss of independence. The simplest and ...
