Community-setting pneumonia-associated hospitalizations by level of urbanization-New York City versus other areas of New York State, 2010-2014.

BACKGROUND: New York City (NYC) reported a higher pneumonia and influenza death rate than the rest of New York State during 2010-2014. Most NYC pneumonia and influenza deaths are attributed to pneumonia caused by infection acquired in the community, and these deaths typically occur in hospitals. METHODS: We identified hospitalizations of New York State residents aged ≥20 years discharged from New York State hospitals during 2010-2014 with a principal diagnosis of community-setting pneumonia or a secondary diagnosis of community-setting pneumonia if the principal diagnosis was respiratory failure or sepsis. We examined mean annual age-adjusted community-setting pneumonia-associated hospitalization (CSPAH) rates and proportion of CSPAH with in-hospital death, overall and by sociodemographic group, and produced a multivariable negative binomial model to assess hospitalization rate ratios. RESULTS: Compared with non-NYC urban, suburban, and rural areas of New York State, NYC had the highest mean annual age-adjusted CSPAH rate at 475.3 per 100,000 population and the highest percentage of CSPAH with in-hospital death at 13.7%. NYC also had the highest proportion of CSPAH patients residing in higher-poverty-level areas. Adjusting for age, sex, and area-based poverty, NYC residents experienced 1.3 (95% confidence interval [CI], 1.2-1.4), non-NYC urban residents 1.4 (95% CI, 1.3-1.6), and suburban residents 1.2 (95% CI, 1.1-1.3) times the rate of CSPAH than rural residents. CONCLUSIONS: In New York State, NYC as well as other urban areas and suburban areas had higher rates of CSPAH than rural areas. Further research is needed into drivers of CSPAH deaths, which may be associated with poverty.

Burden of Adult Community-acquired, Health-care-Associated, Hospital-Acquired, and Ventilator-Associated Pneumonia: New York City, 2010 to 2014.

BACKGROUND: Although pneumonia is a leading cause of death in New York City (NYC), limited data exist about the settings in which pneumonia is acquired across NYC. Cases of pneumonia acquired in community settings are more likely to be preventable with vaccines and treatable with first-line antibiotics than those acquired in noncommunity settings. The objective of this study was to estimate the burden of hospitalizations associated with community-acquired (CAP), health-care-associated (HCAP), hospital-acquired (HAP), and ventilator-associated (VAP) pneumonia from 2010 to 2014. METHODS: This retrospective analysis was performed by using an all-payer reporting system of hospital discharges that included NYC residents aged ≥ 18 years. Pneumonia-associated hospitalizations were defined as any hospitalization that included a diagnostic code for pneumonia among any of the discharge diagnoses. Using published clinical guidelines, we classified hospitalizations into mutually exclusive categories of CAP, HCAP, HAP, and VAP and defined pneumonia acquired in the community setting as the combination of CAP and HCAP. RESULTS: Of 4,614,108 hospitalizations during the reporting period, 283,927 (6.2%) involved pneumonia. Among pneumonia-associated hospitalizations, 154,158 (54.3%) were CAP, 85,656 (30.2%) were HCAP, 39,712 (14.0%) were HAP, and 4,401 (1.6%) were VAP. Death during hospitalization occurred in 7.9% of CAP-associated hospitalizations, compared with 15.6% of HCAP-associated hospitalizations, 20.7% of HAP-associated hospitalizations, and 21.6% of VAP-associated hospitalizations. CONCLUSIONS: Most pneumonia-associated hospitalizations in NYC involve pneumonias acquired in the community setting. Although 15.6% of pneumonia-associated hospitalizations were categorized as HAP or VAP, these pneumonias accounted for > 25% of deaths from pneumonia-associated hospitalizations. Public health pneumonia prevention efforts need to target both community and hospital settings.
