Evaluating capacity to live independently and safely in the community: Performance Assessment of Self-care Skills.

To determine clients' capacity for community living, occupational therapists must use measures that capture the person-task-environment transaction and compare clients' task performance to a performance standard. The Performance Assessment of Self-care Skills, a performance-based, criterion-referenced, observational tool, fulfills this purpose. In this practice analysis, using data from this tool from multiple clinical studies (N = 941), the authors describe tasks that clients from various diagnostic populations could and could not perform independently and safely. For clinicians, the Performance Assessment of Self-care Skills can be used to identify which daily tasks are compromised and the point of task breakdown, as well as to provide guidance about potential interventions.

Association between Cerebral Performance Category, Modified Rankin Scale, and discharge disposition after cardiac arrest.

BACKGROUND: Cerebral Performance Category (CPC), Modified Rankin Scale (mRS) and discharge disposition are commonly used to determine outcomes following cardiac arrest. This study tested the association between these outcome measures. METHODS: Retrospective chart review of subjects who survived to hospital discharge between 1/1/2006 and 12/31/2009 was conducted. Charts were reviewed for outcomes (CPC, mRS, and discharge disposition). Discharge disposition was classified in 6 categories: home with no services, home with home healthcare, acute rehabilitation facility, skilled nursing facility, long term acute care facility, and hospice. Intra-and inter-rater reliabilities were calculated for outcome measures. Rates of "good outcome" (defined as a CPC of 1-2, mRS of 0-3, or discharge disposition to home or acute rehabilitation facility) were also determined. Kendall's tau correlation coefficients explored relationships among measures. RESULTS: A total of 211 charts were reviewed. Mean age was 60 years (SD 16), the majority (75%) were white males, in- and out-of hospital cardiac arrests were equally prevalent, and ventricular dysrhythmia was most common (N=109, 52%). Half of the subjects were comatose following resuscitation and 75 (35%) received therapeutic hypothermia. Inter-rater percentage agreement for CPC and mRS abstraction was 95.24% (kappa 0.89, p<0.001) and 95.24% (kappa 0.90, p<0.001) respectively. "Good outcomes" were found in 44 subjects (20%) using the CPC definition, 47 subjects (22%) using the mRS definition, and 129 subjects (61%) subjects using discharge disposition definition. There was fair relationship between the CPC and mRS (tau 0.43) and poor relationships between CPC and discharge disposition (tau 0.23) and between mRS and discharge disposition (tau 0.25). CONCLUSIONS: Determination of the CPC, mRS and discharge disposition at hospital discharge is reliable from chart review. These instruments provide widely differing estimates of "good outcome". Agreement between these measures ranges from poor to fair. A more nuanced outcome measure designed for the post-cardiac arrest population is needed.

Neurological and functional status following cardiac arrest: method and tool utility.

INTRODUCTION: Assessing the neurological and disability status of cardiac arrest (CA) survivors is important for evaluating the outcomes of resuscitation interventions. The Cerebral Performance Category (CPC)--the standard outcome measurement after CA--has been criticized for its poorly defined, subjective criteria, lack of information regarding its psychometric properties, and poor relationships with long-term measures of disability and quality of life (QOL). This study examined the relationships among the CPC and measures of global disability and QOL at discharge from the hospital and at 1 month after CA. METHODS: Twenty-one CA survivors participated in the study. A medical chart review was conducted at the time of discharge to determine CPC and Modified Rankin Scale (mRS) scores, while 1-month in-person interview was conducted to collect mRS and Health Utilities Index Mark 3 (HUI3) scores. Data collected during the interview were used to determine follow-up CPC scores. RESULTS: The strength of relationships among measures at discharge and 1 month ranged between fair to good. An examination of scatter plots revealed substantial variability and a wide distribution of chart review and 1-month mRS and HUI3 scores within each CPC category. CPC scores obtained through chart review were significantly better than the CPC 1-month scores, thus overestimating the participants' cognitive and disability status 1 month later. CONCLUSION: When compared to disability and quality of life measures, it is apparent that the CPC has limited ability to discriminate between mild and moderate brain injury. The validity of using the chart review method for obtaining scores is questionable.
