Introduction: Postoperative delirium is associated with opioid use in the elderly and is a common complication of geriatric hip fractures, with reported incidences from 16% to 70%. Intravenous (IV) acetaminophen is a safe and efficacious medication in elderly patients and has been shown to reduce use of opioids after hip fracture. At our institution, IV acetaminophen was implemented for the first 24 hours postoperatively as part of a multimodal pain control regimen for geriatric hip fracture patients. Methods: A retrospective review of 123 hip fragility fracture patients older than 60 years from January 2016 to December 2016 was performed. Delirium was identified using a validated chart–based review tool. The rate of delirium, as well as length of stay, pain scores, opioid administration, need for one-to-one supervision, and readmissions were analyzed. Results: Sixty-five patients (52.8%) received IV acetaminophen during this period. No notable differences were found in baseline characteristics between groups. Ten of 65 patients receiving IV acetaminophen postoperatively experienced delirium compared with 19 of 58 who did not receive the medication (15.4% versus 32.8%, P = 0.024). The IV acetaminophen group also required fewer doses of IV opioids on postoperative day 1 (0.37 versus 1.19 doses, P = 0.008), were less likely to require one-to-one supervision (9.2% versus 24.1%, P = 0.025), and had shorter lengths of hospital stay (6.37 versus 8.47 days, P = 0.037). Readmission rates and discharge dispositions did not vary with significance between the two groups. Conclusion: The inclusion of IV acetaminophen as part of a multimodal pain regimen led to fewer episodes of delirium in this study. The reduced use of opioids immediately after surgery may have been a large factor in this outcome. Lower delirium rates may reduce the utilization of inpatient resources for direct patient supervision and provide for shorter hospital stays.

IMPORTANCE Surgeons must balance management of acute postoperative pain with opioid stewardship. Patient-centered methods that immediately evaluate pain and opioid consumption can be used to guide prescribing and shared decision-making.OBJECTIVE To assess the difference between the number of opioid tablets prescribed and the selfreported number of tablets taken as well as self-reported pain intensity and ability to manage pain after orthopedic and urologic procedures with use of an automated text messaging system. DESIGN, SETTING, AND PARTICIPANTSThis quality improvement study was conducted at a large, urban academic health care system in Pennsylvania. Adult patients (aged Ն18 years) who underwent orthopedic and urologic procedures and received postoperative prescriptions for opioids were included. Data were collected prospectively using automated text messaging until postoperative day 28, from May 1 to December 31, 2019. MAIN OUTCOMES AND MEASURESThe primary outcome was the difference between the number of opioid tablets prescribed and the patient-reported number of tablets taken (in oxycodone 5-mg tablet equivalents). Secondary outcomes were self-reported pain intensity (on a scale of 0-10, with 10 being the highest level of pain) and ability to manage pain (on a scale of 0-10, with 10 representing very able to control pain) after orthopedic and urologic procedures. RESULTSOf the 919 study participants, 742 (80.7%) underwent orthopedic procedures and 177 (19.2%) underwent urologic procedures. Among those who underwent orthopedic procedures, 384 (51.8%) were women, 491 (66.7%) were White, and the median age was 48 years (interquartile range [IQR], 32-61 years); 514 (69.8%) had an outpatient procedure. Among those who underwent urologic procedures, 145 (84.8%) were men, 138 (80.7%) were White, and the median age was 56 years (IQR, 40-67 years); 106 (62%) had an outpatient procedure. The mean (SD) pain score on day 4 after orthopedic procedures was 4.72 (2.54), with a mean (SD) change by day 21 of −0.40 (1.91). The mean (SD) ability to manage pain score on day 4 was 7.32 (2.59), with a mean (SD) change of −0.80 (2.72) by day 21. The mean (SD) pain score on day 4 after urologic procedures was 3.48 (2.43), with a mean (SD) change by day 21 of −1.50 (2.12). The mean (SD) ability to manage pain score on day 4 was 7.34(2.81), with a mean (SD) change of 0.80 (1.75) by day 14. The median quantity of opioids prescribed for patients who underwent orthopedic procedures was high compared with self-reported consumption (20 tablets [IQR,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] vs 6 tablets used [IQR, 0-14 tablets]), similar to findings for patients who underwent urologic procedures (7 tablets [IQR,[5][6][7][8][9][10] vs 1 tablet used [IQR,[0][1][2][3][4]). Over the study period, 9452 of 15 581 total tablets prescribed (60.7%) were unused. A total of 589 patients (64.1%) used less than half of the amount prescribed, and 256 patients (27.8%) Key PointsQuestion Are the quantities of shortterm opioid prescr...
