Economic costs of dysphagia among hospitalized patients.

OBJECTIVES/HYPOTHESIS: Difficulties swallowing may lead to aspiration pneumonia and death. In a hospital setting where patients are admitted for other causes, we hypothesized that the additional burden of a swallow problem would increase length of stay, rate of pneumonia, cost, readmissions, and morbidity compared to those without dysphagia.

STUDY DESIGN

Retrospective parallel cohort study.

METHODS

A study of patients admitted to the hospital with hip/femur fracture was completed. Two groups were identified and compared: those with a coded diagnosis of dysphagia (n = 165) in addition to hip/femur fracture (HF + D), and a group with hip fracture alone (HF-D) (n = 2,288) (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification). Number of inpatient days, cost per patient, diagnosis of pneumonia, 30-day readmission, and mortality rates were compared.

RESULTS

For those in the HF + D group, mean age was 85 years compared to 78 years in the HF-D group (P < .05); length of stay was 32 days, more than twice that of the HF-D group (14 days) (P < .05). Mortality within 30 days of admission was significantly higher (18% vs. 4%,respectively) but 30-day readmission rate was similar (8% vs. 11%, respectively). Rate of aspiration pneumonia was 14 times greater in HF + D (9.7%) compared with HF-D (0.7%). Average admission cost was NZD$36,913 (HF + D) compared with NZD$22,222 (HF-D) (P < .05).

CONCLUSIONS

Complaint of dysphagia, in addition to hip fracture, increases a patient's average admission cost by 60%. It is associated with increased aspiration pneumonia and greater mortality. Dysphagia screening at admission to hospital would allow early identification of swallow compromise and may prevent complications and reduce costs.
