Evaluation of risk factors for oral infection with potential for spread in a 1-year cohort study

Association and risk factors of healthcare-associated infection and burden of illness among chemotherapy-induced ulcerative mucositis patients

Objectives

To evaluate the association and risk factors of healthcare-associated infection (HAI) and burden of illness among chemotherapy-induced ulcerative mucositis (UM) patients.

Methods

For this research, US National Inpatient Sample database 2017 was utilized to study UM patients. The association of healthcare-associated infection-related burden of illness among UM patients was assessed on the outcome––length of hospital stays (LOS), total charges, in-hospital mortality, and discharge disposition.

Result

In 2017, there were 11,350 adult (> 18 years of age) UM patients, among them there were 415 (3.5%) HAI. After adjusting for patient and clinical characteristics, UM patients with HAI were most likely to have higher total charges and longer LOS (1.91; 95% CIs: 1.51–2.41; P < 0.001; 1.84; 95% CIs: 1.53–2.21; P < 0.001) than those without HAI. Further, mortality was not significantly different. UM patients with HAI were less likely to have higher burden of illness who were younger, females, those living in non-metropolitan or micropolitan counties, and those with lower co-morbidity score. Additionally, UM patients with HAI were more likely to discharge to skilled nursing facility (SNF), intermediate care facility (ICF), and another type of facility (ATF), (aOR = 2.58 (1.16–5.76), P = 0.02), than they were to discharge to self-care or home care.

Conclusion

UM patients with HAI were more likely to have higher burden of illness and more likely to discharged to the SNF, ICF, and ATF rather than to home or self-care.

Clinical relevance

UM patients when associated with HAI have higher burden of illness; a tailored approach to oral care might prevent HAIs and burden of illness among UM.

Health status in patients hospitalised for severe odontogenic infections

OBJECTIVE

Previous findings refer to certain predisposing medical conditions that compound the risk of developing severe and potentially lethal acute odontogenic infections (OI). The objective of this study was to clarify this rationale and infection severity in general.

MATERIAL AND METHODS

Records of patients aged ≥18 years requiring hospital care for deep OI were retrospectively investigated. The main outcome variable was need for intensive care unit (ICU) treatment. Additional outcome variable was occurrence of infection complications and/or distant infections. Several parameters describing patients' prior health and recent dental treatment were set as independent variables.

RESULTS

Of the 303 acute OI patients included, 71 patients (23%) required treatment in the ICU, with no significant difference between previously healthy and patients with disease history. OIs originating from teeth in the mandible compared with maxilla had 7.8-fold risk (p = .007) for ICU treatment in binary logistic regression analyses. Elevated levels of infection parameters at hospital admission predicted further ICU stay. Infection complications and/or distant infections occurred in 7.6% of patients, of which septicaemia and pneumonia were the most common. The mortality rate was 0.3%. Infection complications and/or distant infections occurred significantly more often in smokers (p = .001) and in patients with excessive consumption of alcohol or drugs (p = .025), however smoking showed 3.5-folded independent risk for infection complications and/or distant infections (p = .008) in logistic regression.

CONCLUSIONS

Severe OIs often occur in previously healthy patients. Smokers in particular are prone to the most serious OIs.
