National Institutes of Health Stroke Scale Reporting in Medicare Claims Data: Reporting in the First 3 Years.

BACKGROUND: Since 2016, hospitals have been able to document International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for the National Institutes of Health Stroke Scale (NIHSS). As of 2023, the Centers for Medicare & Medicaid Services uses NIHSS as a risk adjustment variable. We assessed associations between patient- and hospital-level variables and contemporary NIHSS reporting. METHODS: We performed a retrospective cross-sectional analysis of 2019 acute ischemic stroke admissions using deidentified, national 100% inpatient Medicare Fee-For-Service data sets. We identified index acute ischemic stroke admissions using the ICD-10-CM code I63.x and abstracted demographic information, medical comorbidities, hospital characteristics, and NIHSS. We linked Medicare and Mount Sinai Health System (New York, NY) registry data from 2016 to 2019. We calculated NIHSS documentation at the patient and hospital levels, predictors of documentation, change over time, and concordance with local data. RESULTS: There were 231 383 index acute ischemic stroke admissions in 2019. NIHSS was documented in 44.4% of admissions and by 66.5% of hospitals. Hospitals that documented ≥1 NIHSS were more commonly teaching hospitals (39.0% versus 5.5%; standardized mean difference score, 0.88), stroke certified (37.2% versus 8.0%; standardized mean difference score, 0.75), higher volume (mean, 80.8 [SD, 92.6] versus 6.33 [SD, 14.1]; standardized mean difference score, 1.12), and had intensive care unit availability (84.9% versus 23.2%; standardized mean difference score, 1.57). Adjusted odds of documentation were lower for patients with inpatient mortality (odds ratio, 0.64 [95% CI, 0.61-0.68]; P<0.0001), in nonmetropolitan areas (odds ratio, 0.49 [95% CI, 0.40-0.61]; P<0.0001), and male sex (odds ratio, 0.95 [95% CI, 0.93-0.97]; P<0.0001). NIHSS was documented for 52.9% of Medicare cases versus 93.1% of registry cases, and 74.7% of Medicare NIHSS scores equaled registry admission NIHSS. CONCLUSIONS: Missing ICD-10-CM NIHSS data remain widespread 3 years after the introduction of the ICD-10-CM NIHSS code, and there are systematic differences in reporting at the patient and hospital levels. These findings support continued assessment of NIHSS reporting and caution in its application to risk adjustment models.

Palliative Care Specialist Access is Associated With Rankings of Hospital Quality.

CONTEXT: Increasing evidence has shown that access to specialty palliative care, particularly outpatient palliative care clinics, can yield improved health outcomes and be a marker of hospital quality. OBJECTIVE: To determine whether an association exists between access to specialty palliative care programs and hospital rankings found in the 2020-2021 U.S. News & World Report Best Hospitals. METHODS: This study used publicly available data from the Center to Advance Palliative Care (CAPC) Provider Directory to determine access to in-patient and out-patient palliative care in the 2020-2021 U.S. News & World Report Best Hospitals Rankings. Descriptive statistics and chi-squares were performed. Data were also analyzed across the four U.S. Census Bureau regions (Northeast, South, Midwest, West). RESULTS: Around 100% of the Top 20 hospitals include hospital-based palliative care consultation teams, and 95% offered outpatient palliative care. Of the second cohort of 83 hospitals, 99% offered inpatient palliative care, and 65% offered outpatient palliative care. Of the third cohort of 75 hospitals ranked, 96% had inpatient palliative care services, while only 41.3% offered outpatient palliative care. This represents a significant association between rank position and access to outpatient palliative care (P < 0.01). Ranked hospitals also have significantly higher access to hospital-based palliative care teams compared to the national prevalence rate (P < 0.01). CONCLUSION: These findings reflect the association of access to specialty palliative care with USNWR rankings for hospital quality. Further study is necessary to determine the specific influence of access to palliative care and USNWR rank position.
