Insights
Hospital-acquired conditions (HACs) are rare in head and neck cancer surgery. However, HACs significantly increase mortality, complications, and costs, necessitating universal prevention strategies.
Area of Science:
- Oncology
- Healthcare Management
- Patient Safety
Background:
- The Centers for Medicare and Medicaid Services penalize hospitals for 10 specific hospital-acquired conditions (HACs).
- Head and neck cancer (HNCA) surgery patients may be at risk for HACs.
- Understanding HAC incidence and impact in HNCA surgery is crucial for quality improvement.
Purpose of the Study:
- To determine the incidence of HACs in patients undergoing head and neck cancer surgery.
- To assess the association of HACs with in-hospital mortality, complications, length of hospitalization, and costs.
Main Methods:
- Retrospective cross-sectional study using Nationwide Inpatient Sample data (2001-2008).
- Analysis of 123,662 patients undergoing ablative procedures for malignant oral cavity, laryngeal, hypopharyngeal, or oropharyngeal neoplasms.
- Cross-tabulations and multivariate regression modeling were employed.
Main Results:
- Hospital-acquired conditions (HACs) occurred in less than 1% of cases, with vascular catheter-associated infection being the most common (>70%).
- HACs were significantly associated with urgent/emergent admission, major surgery, flap reconstruction, and advanced comorbidity.
- HACs significantly increased in-hospital mortality, surgical and medical complications, length of hospitalization, and hospital costs.
Conclusions:
- Hospital-acquired conditions (HACs) are infrequent in head and neck cancer surgery patients.
- Poor predictability and the universal nature of human error underscore the need for innovative, widespread measures to reduce HACs.
- Universal strategies are essential to mitigate HACs across diverse patient populations and healthcare settings.
Objectives/Hypothesis:
The Centers for Medicare and Medicaid Services has identified 10 hospital-acquired conditions (HACs) for which they will not reimburse care. We sought to determine the incidence of HACs in head and neck cancer (HNCA) surgery and the association with in-hospital mortality, complications, length of hospitalization, and costs.
Study Design:
Retrospective cross-sectional study.
Methods:
Discharge data from the Nationwide Inpatient Sample for 123,662 patients who underwent an ablative procedure for a malignant oral cavity, laryngeal, hypopharyngeal, or oropharyngeal neoplasm during 2001-2008 were analyzed using cross-tabulations and multivariate regression modeling.
Results:
HACs occurred in <1% of cases, with vascular catheter-associated infection comprising >70% of all HACs. The occurrence of HACs was significantly associated with urgent or emergent admission (odds ratio [OR]=2.0, P=.004), major surgical procedures (OR=2.3, P<.001), flap reconstruction (OR=3.5, P<.001), and advanced comorbidity (OR=2.0, P<.001). There was no association between HACs and hospital size, location, ownership, volume status, or safety-net burden. HACs were significantly associated with in-hospital mortality (OR=3.8, P=.001), surgical complications (OR=4.9, P<.001), and medical complications (OR=5.6, P<.001). After controlling for all other variables, HACs were associated with significantly increased length of hospitalization and hospital-related costs, with vascular catheter-associated infection and foreign object after surgery associated with the greatest increase in length of stay and costs.
Conclusions:
HACs are uncommon events in HNCA surgical patients. Because prediction of HACs is poor and the potential for human error crosses demographic, geographic, and structural boundaries, universal innovative measures to reduce the occurrence of HACs are needed.
