Summary of "Geographical Differences in Comorbidity Burden and Outcomes in Adults With Syncope Hospitalizations in Canada."

A recent study found that rates of hospitalization for syncope vary across provinces; however, it is unknown whether differences in comorbidity burden and outcomes also exist. The Canadian Institute for Health Information Discharge Abstract Database was used to identify primary syncope hospitalizations (ICD-10 code R55) from 2004 to 2013 for all provinces (except Quebec). Charlson comorbidity score was calculated from comorbidities at the time of hospitalization. Outcomes were defined as in-hospital mortality, 30-day readmission for any cause, and syncope. Logistic regression models were constructed for odds ratios (ORs) and 95% confidence intervals (CIs) to estimate interprovincial differences in outcomes. The interprovincial range (IPR) for mean age was 61.1 ± 17.5 to 73.7 ± 16.3 years, and at least half were male patients. There were significant differences in comorbidity burden across provinces (P < 0.01); however, the majority of patients had a Charlson comorbidity score = 0 (IPR, 53.9%- 71.9%). In multivariable analysis, compared with Ontario, in-hospital mortality was higher for British Columbia (OR, 1.59; 95% CI, 1.22-2.06), Nova Scotia (OR, 1.67; 95% CI, 1.05-2.65), and Newfoundland (OR, 2.27; 95% CI, 1.29-4.00); 30-day readmission for any cause was higher for British Columbia (OR, 1.15; 95% CI, 1.06-1.26), Alberta (OR, 1.19; 95% CI, 1.07-1.31), Manitoba (OR, 1.36; 95% CI, 1.18-1.56), and Prince Edward Island (OR, 1.38; 95% CI, 1.0-1.89), and all outcomes were higher in Saskatchewan. There is significant interprovincial heterogeneity in comorbidity burden and outcomes for hospitalizations for syncope. Future research evaluating whether standardized practices for management of syncope reduce variability and improve healthcare utilization and costs is needed.

Medical and Biotech [MESH] Definitions

The presence of co-existing or additional diseases with reference to an initial diagnosis or with reference to the index condition that is the subject of study. Comorbidity may affect the ability of affected individuals to function and also their survival; it may be used as a prognostic indicator for length of hospital stay, cost factors, and outcome or survival.

Measure of the burden of disease using the disability-adjusted-life-year (DALY). This time-based measure combines years of life lost due to premature mortality and years of life lost due to time lived in states of less than full health. The metric was developed to assess the burden of disease consistently across diseases, risk factors and regions.

A transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., BRAIN ISCHEMIA). Presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope. (From Adams et al., Principles of Neurology, 6th ed, pp367-9)

A condition of fainting spells caused by heart block, often an atrioventricular block, that leads to BRADYCARDIA and drop in CARDIAC OUTPUT. When the cardiac output becomes too low, the patient faints (SYNCOPE). In some cases, the syncope attacks are transient and in others cases repetitive and persistent.

Diseases of the ninth cranial (glossopharyngeal) nerve or its nuclei in the medulla. The nerve may be injured by diseases affecting the lower brain stem, floor of the posterior fossa, jugular foramen, or the nerve's extracranial course. Clinical manifestations include loss of sensation from the pharynx, decreased salivation, and syncope. Glossopharyngeal neuralgia refers to a condition that features recurrent unilateral sharp pain in the tongue, angle of the jaw, external auditory meatus and throat that may be associated with SYNCOPE. Episodes may be triggered by cough, sneeze, swallowing, or pressure on the tragus of the ear. (Adams et al., Principles of Neurology, 6th ed, p1390)
