Clinician judgment vs formal scales for predicting intracerebral hemorrhage outcomes.

ABSTRACT:

Objective

To compare the performance of formal prognostic instruments vs subjective clinical judgment with regards to predicting functional outcome in patients with spontaneous intracerebral hemorrhage (ICH).

Methods

This prospective observational study enrolled 121 ICH patients hospitalized at 5 US tertiary care centers. Within 24 hours of each patient's admission to the hospital, one physician and one nurse on each patient's clinical team were each asked to predict the patient's modified Rankin Scale (mRS) score at 3 months and to indicate whether he or she would recommend comfort measures. The admission ICH score and FUNC score, 2 prognostic scales selected for their common use in neurologic practice, were calculated for each patient. Spearman rank correlation coefficients (r) with respect to patients' actual 3-month mRS for the physician and nursing predictions were compared against the same correlation coefficients for the ICH score and FUNC score.

Results

The absolute value of the correlation coefficient for physician predictions with respect to actual outcome (0.75) was higher than that of either the ICH score (0.62, p = 0.057) or the FUNC score (0.56, p = 0.01). The nursing predictions of outcome (r = 0.72) also trended towards an accuracy advantage over the ICH score (p = 0.09) and FUNC score (p = 0.03). In an analysis that excluded patients for whom comfort care was recommended, the 65 available attending physician predictions retained greater accuracy (r = 0.73) than either the ICH score (r = 0.50, p = 0.02) or the FUNC score (r = 0.42, p = 0.004).

Conclusions

Early subjective clinical judgment of physicians correlates more closely with 3-month outcome after ICH than prognostic scales.

Project description:Background and purposeSeizures commonly occur in patients with intracerebral hemorrhage (ICH). Anticonvulsants are commonly used for preventing seizures in patients with ICH. Thus, patients with ICH at high risk of seizures must be identified. The study aims to elucidate whether double the score of cortex involvement in ICH patients can increase accuracy of CAVE score for predicting late seizures.MethodThis retrospective analysis of the medical records of surviving patients admitted between June 1, 2013, and December 31, 2019. Validated the CAVE score and modified it (CAVE2). The main outcome of patients with ICH was seizures. The first seizures occurring within 7 days after a stroke were defined as early seizures. Seizures occurring after 1 week of stroke onset, including patients who had experienced early seizures or patients who had not, were defined as late seizures. CAVE and CAVE2 scores were validated using the cohort. The accuracy and discrimination of those two scores were accessed by the area under the operating characteristic curve. Akaike information criterion, integrated discrimination improvement, and continuous net reclassification improvement were used to assess the performance of the CAVE and CAVE2 scores.ResultsIn the cohort showed that late seizures occurred in 12.7% (52/408) of patients with ICH. Male sex, age > 65 years, cortex involvement, and early seizures were associated with the occurrence of late seizures, with odds ratios of 2.09, 2.04, 4.12, and 3.78, respectively. The risk rate of late seizures was 6.66% (17/255), 14.8% (17/115), and 47.4% (18/38) for CAVE scores ≤ 1, 2, and ≥ 3, and 4.6% (12/258), 18.3% (13/71), and 54.4 (20/37) for CAVE2 scores ≤ 1, 2, and ≥ 3 respectively. The C-statistics for the CAVE and CAVE2 scores were 0.73 and 0.74 respectively.ConclusionThe CAVE score can identify patients with ICH and high risk for late seizures. The CAVE can be modified by changing the score of cortex involvement to 2 points to improve accuracy in predicting late seizures in patients with ICH.

Project description:ImportancePatients who have experienced intracerebral hemorrhage (ICH) appear to develop cognitive impairment at high rates, both early after ICH and over the long term.ObjectiveTo identify and compare risk factors for early and delayed dementia after ICH.Design, setting, and participantsA longitudinal study enrolled patients who had experienced ICH from January 1, 2006, to December 31, 2013. A total of 738 participants 18 years or older, without pre-ICH dementia, who presented to a tertiary care academic institution with primary ICH were included in the analyses of early post-ICH dementia (EPID). After accounting for incident dementia and mortality at 6 months, 435 participants were included in the analyses of delayed post-ICH dementia (DPID).ExposuresIntracerebral hemorrhage.Main outcomes and measuresCognitive performance was captured using the modified Telephone Interview for Cognitive Status test. Outcomes included EPID, diagnosed within 6 months after ICH, and DPID, diagnosed beyond 6 months after ICH.ResultsAmong 738 patients who had experienced ICH (mean [SD] age, 74.3 [12.1] years; 384 men [52.0%]), 140 (19.0%) developed dementia within 6 months. A total of 435 patients without dementia at 6 months were followed up longitudinally (median follow-up, 47.4 months; interquartile range, 43.4-52.1 months), with an estimated yearly incidence of dementia of 5.8% (95% CI, 5.1%-7.0%). Larger hematoma size (hazard ratio [HR], 1.47 per 10-mL increase; 95% CI, 1.09-1.97; P < .001 for heterogeneity) and lobar location of ICH (HR, 2.04; 95% CI, 1.06-3.91; P = .02 for heterogeneity) were associated with EPID but not with DPID. Educational level (HR, 0.60; 95% CI, 0.40-0.89; P < .001 for heterogeneity), incident mood symptoms (HR, 1.29; 95% CI, 1.02-1.63; P = .01 for heterogeneity), and white matter disease as defined via computed tomography (HR, 1.70; 95% CI, 1.07-2.71; P = .04 for heterogeneity) were associated with DPID but not EPID.Conclusions and relevanceIncident dementia early after ICH is strongly associated with hematoma size and location. Delayed incident dementia is frequent among patients who have experienced ICH and is not prominently associated with acute characteristics of ICH. These findings suggest the existence of heterogeneous biological mechanisms accounting for early vs delayed cognitive decline among patients who have experienced ICH.
