Efficacy and Safety of a Patient Selection Tool for Predicted Discharge at an Ambulatory Surgical Center: A Pilot Study.

Background: There is a paucity of validated risk stratification tools to assess which patients can safely and predictably undergo outpatient total hip (THA) or knee arthroplasty (TKA) in an ambulatory surgery center (ASC). Methods: Our novel patient selection tool was prospectively applied to 190 consecutive primary THA and TKA performed by a single surgeon at a single ASC. We identified the proportion of patients discharged home the same day, those requiring a one-night stay, or those with failed discharge within 23 hours. A retrospective chart review was performed to determine if any demographic parameters were risk factors for an overnight stay. Results: Overall, 190 (100%) patients selected for outpatient THA and TKA were discharged home within 23 hours. One hundred and four patients (55%) were discharged the same day of surgery, whereas 86 (45%) required overnight stay and were discharged on postoperative day 1. Female sex (odds ratio [OR]: 4.1, 95% confidence interval [CI]: 2.0-8.2, P < .001), THA (OR: 2.5, 95% CI: 1.1-5.5, P = .022), and heavier body mass index (OR: 1.0, 95% CI: 1.0-1.2, P = .022) were identified as independent risk factors for staying overnight in the ASC. Conclusions: In this pilot study, we found that 100% of outpatient THA and TKA-eligible patients were able to be discharged home by postoperative day 1. Additionally, we found that this selection tool is safe and effective at predicting short-stay discharge in an ASC.

A Novel Patient Selection Tool Is Highly Efficacious at Identifying Candidates for Outpatient Surgery When Applied to a Nonselected Cohort of Patients in a Community Hospital.

BACKGROUND: There is a paucity of validated selection tools to assess which patients can safely and predictably undergo same-day or 23-hour discharge in a community hospital. The purpose of this study was to assess the ability of our patient selection too to identify patients who are candidates for outpatient total joint arthroplasty (TJA) in a community hospital. METHODS: A retrospective review of 223 consecutive (unselected) primary TJAs was performed. The patient selection tool was retrospectively applied to this cohort to determine eligibility for outpatient arthroplasty. Utilizing length of stay and discharge disposition, we identified the proportion of patients discharged home within 23 hours. RESULTS: We found that 179 (80.1%) patients met eligibility criteria for short-stay TJA. Of the 223 patients in this study, 215 (96.4%) patients were discharged home; 17 (7.9%) were on the day of surgery, and 190 (88.3%) within 23 hours. Of the 179 eligible patients for short-stay discharge, 155 (86.6%) patients were discharged home within 23 hours. Overall, the sensitivity of the patient selection tool was 79%, the specificity was 92%, the positive predictive value was 87% and the negative predictive value was 96%. CONCLUSION: In this study, we found that more than 80% of patients undergoing TJA in a community hospital are eligible for short-stay arthroplasty with this selection tool. We found that this selection tool is safe and effective at predicting short-stay discharge. Further studies are needed to better ascertain the direct effects of these specific demographic traits on their effects on short-stay protocols.

Understanding Patient Perspectives Regarding Remote Monitoring Devices Following Total Joint Replacement.

Background: Advances in smart technology have expanded into the field of orthopedic surgery to deliver enhanced patient care. Smart technology has also raised important issues regarding protected patient information. The purpose of this study is to determine patient preferences regarding smart technology in their postarthroplasty care. Methods: Patient surveys were administered in the office setting of 2 adult reconstructive orthopedic surgeons during a 4-week period. Surveys queried patient demographics, twelve yes/no questions, five continuous agree/disagree statements, and a single free-text question. Logistic regression and statistical significance testing were performed. Results: Of the study patients, 83.6% were willing to wear a device. Women were more likely to consent to a monitoring device and have activity data collected than men (P < .05). Younger patients were more likely to consent to a device and have data collected than octogenarians. Nearly 90% of respondents indicated peace of mind with data being constantly tracked. However, 64% of respondents had hesitations about a surgically implanted device that was independent of a previous arthroplasty surgery (P < .05). Conclusions: Patients are comfortable with smart technology being involved in their postoperative care, especially younger patients and women. Older individuals, possibly with less experience using smart technology in their lives, were not as willing to wear smart devices or have their data collected. Nearly two-thirds of patients had hesitations about surgically implanted smart devices. Further investigation is needed to understand hesitations concerning smart implants as the orthopedic community enters an era of commercially available smart implants in total joint arthroplasty.
