Abstract

Background

Sickle cell crisis hospitalizations are emotionally and financially burdensome to patients and healthcare systems, and processes to decrease the frequency or length of stay of these crises should be examined.

Methods

This is a multicenter retrospective hospital record review of sickle cell crisis hospitalizations as defined by ICD-10 codes (D57.1-4), from January 2016 through December 2019, examining inpatient medication administration records and length of stay among admitted adults aged 18–65 years. Patient controlled analgesia orders using morphine, hydromorphone, fentanyl and/or merperidine at any point of an admission (n=188) were compared to admissions without any patient-controlled analgesia orders (n=2,159). The primary end point was hospital length of stay in days. A secondary analysis examining patients with or without greater than four admissions was also conducted.

Results

The 1,675 patients who met criteria comprised 2,347 sickle cell hospitalization during the four years examined. Of those admissions, 188 had at least one patient-controlled analgesic documented in their chart and had an average length of stay of 4.54 days (SD 3.34). The 2,159 admissions without any patient-controlled analgesia had an average length of stay of 5.74 days (SD 4.64). The difference of 1.2 days between the groups was statistically significant (p≤0.0001) using a Wilcoxon signed-rank test.

Conclusion

Among patients with sickle cell crises who required inpatient hospitalizations, the use of patient-controlled analgesia demonstrated a statistically significant reduction of 1.2 days in their total length of stay. These findings support potentially changing hospital protocols to increase patient-controlled analgesia utilization.

Erratum

Figure 1 replaced with a label correction. The label was redundant with the figure legend and referred to reference color in graph as red instead of orange.
