Algorithms first assess the easiest ADL and move on to harder ones as needed. For example, the simple algorithm first assesses difficulty eating or toileting, or both. The threshold is no difficulty
with either. Those who report buy BIBW2992 difficulty are assigned either stage III or stage IV. If the threshold is met, then transferring/dressing is assessed. If this threshold is not met, stage II is assigned; otherwise walking and bathing are assessed. If this threshold is not met, stage I is assigned. Stage 0 is assigned if there is no difficulty with any ADL. The following 2 case examples illustrate the reduced complexity of stage assignment using the simple
versus complex staging: • Mr. J is an 87-year-old community-dwelling man with Parkinson’s disease and prostate cancer living with his 82-year-old wife who provides care. He describes some difficulties dressing and bathing. He notes a lot of difficulty walking but has no difficulty with the remaining ADL. He is assigned stage II according to both algorithms (see figs 1 and 2). Applying the complex algorithm required 3 decision points compared with only 2 with the simple algorithm. Age, ADL stages, self-perceived health, and interview proxy use were assessed using INCB024360 in vivo the baseline LSOA II interview. Baseline physical health conditions were assessed using the questions, “have you ever had…” diabetes, arthritis, respiratory disease (chronic bronchitis, emphysema, or asthma), hypertension, heart disease, stroke, and cancer (excluded those reporting only skin cancer). Baseline urinary and fecal incontinence were determined by self-reported difficulty controlling urination and bowels, respectively. The Disability Phase I Questionnaire contained most of Protein kinase N1 the mental illness and Alzheimer disease questions. Those LSOA II participants
(n=586) who did not receive this questionnaire were excluded from the analysis of these variables. Dementia was defined by reported Alzheimer disease in the past 12 months or using a proxy/assistant because of poor memory, senility, confusion, or Alzheimer disease. Mental illness was defined by requiring a proxy because of other (nondementia) mental health conditions, or reporting having 1 or more of the following disorders in the past 12 months: schizophrenia, paranoid/delusional disorder, bipolar disorder, major depression, severe personality disorder, or other mental/emotional disorder that seriously interfered with the person’s ability to work or attend school or manage day-to-day activities.
