The Price for Delayed Diagnosis of Pediatric Septic Hip: Increased Cost and Poor Outcomes.

Background: Most authors agree that early diagnosis and treatment of pediatric septic hip, within 4 days of onset of symptoms, is crucially important for good outcomes. In healthcare, value is a function of outcome over cost. The purpose of this study was to determine the clinical outcome and cost, therefore value, associated with early versus delayed treatment of pediatric septic arthritis of the hip.

Methods: A retrospective review was performed at a single pediatric hospital. Hospital records over 6 years (2011 to 2016) were examined to identify patients who had undergone treatment for primary septic arthritis of the hip. Patient demographics, clinical data at presentation, treatment information, and follow-up data were recorded. Hospital charges at account level were calculated and compared between groups.

Results: Forty-three subjects were identified for analysis. Twelve presented more than 4 days after the onset of symptoms (delayed diagnosis). There was no difference in patient demographics, Kocher criteria, or initial imaging performed between those with early versus delayed diagnosis. The delayed group had significantly longer length of hospital stay (17 vs. 9 d, P =0.003), follow-up needed (56 vs. 19 wk P =0.001), long-term complications (50% vs. 3%, P =0.000), duration of antibiotics (8 vs. 5.5 wk, P= 0.043), greater number of I&Ds (2 vs. 1, P =0.04), more tissue cultures and blood draws (6 vs. 2, P =0.002; and 3 vs. 2 P =0.009, respectively) and more radiographs taken as outpatients (4 vs. 2, P =0.001, respectively). The average total hospital charge (inpatient and outpatient) was $102,774 in the early diagnosis group and $243,411 in the delayed group ( P =0.012).

Conclusions: Delayed diagnosis of pediatric septic hip correlated with longer length of hospital stay, duration of follow-up, and more long-term complications. These factors contributed to higher total hospital costs and therefore decreased healthcare value.
