Outpatient Versus Inpatient Surgical Fixation of Isolated Ankle Fractures: An Analysis of 90-Day Complications, Readmissions, and Costs

Trends in inpatient versus outpatient upper extremity fracture surgery from 2008 to 2021 and their implications for equitable access: a retrospective cohort study

PURPOSE

The aim of this study is to describe trends in inpatient and outpatient upper extremity fracture surgery between 2008 and 2021, along with identifying patient factors (age, sex, race, socioeconomic status) associated with outpatient surgery.

METHODS

Retrospectively, 12,593 adult patients who underwent upper extremity fracture repair from 2008 to 2021 at one of five urban hospitals in the Northeastern USA were identified. Using Distressed Communities Index (DCI), patients were divided into five quintiles based on their level of socioeconomic distress. Multivariable logistic regression was performed on patients from 2008 to 2019 to identify independent factors associated with outpatient management.

RESULTS

From 2008 to 2019, outpatient procedures saw an average increase of 31%. The largest increases in the outpatient management were seen in humerus (132%) and forearm fractures (127%). Carpal and hand surgeries had the lowest percent increase of 8.1%. Clavicle and wrist fractures were independently associated with outpatient management. Older age, male sex, higher Elixhauser comorbidity index, DCI scores in the 4th or 5th quintile, and fractures of the scapula, humerus, elbow, and forearm were associated with inpatient management. During the onset of the COVID-19 pandemic, there was a decrease in outpatient procedures.

CONCLUSION

There is a shift toward outpatient surgical management of upper extremity fractures from 2008 to 2021. Application of our findings can serve as an institutional guide to allocate patients to appropriate surgical settings. Moreover, physicians and institutions should be aware of the potential socioeconomic disparities and implement plans to allow for equal access to care.

Racial Disparities in Outcomes After Foot and Ankle Surgery: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis delved into the impact of race and ethnicity on outcomes following foot and ankle surgery, an area garnering increasing attention within the medical community. Despite significant literature on postsurgical clinical and functional outcomes, limited research has explored the influence of racial and ethnic factors on postoperative outcomes. In this study, data from 33 relevant studies, involving a total of 557,734 patients, were analyzed to assess outcomes across different racial and ethnic groups. Notably, only 6 studies met the criteria for inclusion in the final meta-analysis due to variations in outcome reporting. Findings revealed disparities in functional scores, pain levels, and resource utilization among different racial and ethnic cohorts. Specifically, non-White and minority patients exhibited higher rates of foot and ankle fractures and lower extremity surgeries, worse functional outcomes, increased pain, longer hospital stays, and a greater incidence of complications compared to their White counterparts. However, some studies presented contradictory results, emphasizing the necessity for further investigation to elucidate these discrepancies fully. This research underscores the importance of considering racial and ethnic factors in foot and ankle surgery outcomes and highlights the need for targeted interventions to address existing disparities.

Safety and Outcome Measures of Ankle Open Reduction and Internal Fixation in an Ambulatory Surgical Center

The transition of traditionally hospital-based orthopedic procedures to the ambulatory surgery center setting provides many benefits from a patient care and financial perspective. Specifically, closed ankle fractures can potentially be managed at such centers without needing hospitalization. Adding to the paucity of data, this study describes the safety, cost, and outcomes of patients undergoing ankle fracture repair in an ambulatory surgery center. A retrospective chart review of 100 patients who underwent ankle fracture open reduction and internal fixation from a single ambulatory surgery center by 1 surgeon were reviewed. Demographic data, surgical characteristics including operating time and cost were collected. Short- and long-term complications, as well as, reoperation rates were reported and functional outcomes were described. Of the 100 patients, 59% were female and the overall average age was 50 ± 16 years. The average cost per case was $8,709.63 ± 6,360.18. The short-term complication rate was 16%, with surgical site infection reported as the most common complication. No postoperative hospital admissions were reported. Planned and unplanned hardware removal was performed in 7% and 5% of patients, respectively. The delayed union rate was 13%, in which 86% shared a history of smoking. Smoking history was the only statistically significant predictor of prolonged bone healing (p = .002). This investigation demonstrates low complications rates for surgeries performed in a surgery center when compared to historical rates of those procedures performed in the hospital. These results suggest that ambulatory surgery center-based ankle fracture repair does not increase complications while may decrease overall cost when compared to ankle ORIF in a hospital setting.

Surgical Setting in Achilles Tendon Repair: How Does It Relate to Costs and Complications?

Background

Primary Achilles tendon repair (ATR) can be performed in ambulatory surgery centers (ASCs) or hospitals. We compared costs and complication rates of ATR performed in these settings.

Methods

We retrospectively queried the electronic medical record of our academic health system and identified 97 adults who underwent primary ATR from 2015 to 2021. Variables were compared between patients treated at ASCs vs those treated in hospitals. We compared continuous variables with Wilcoxon rank-sum tests and categorical variables with χ2 tests. We used an α of 0.05. Multivariable logistic regression was performed to determine associations between surgical setting and costs. Linear regression was performed between each charge subtype and total cost to identify which charge subtypes were most associated with total cost.

Results

Patients who underwent ATR in hospitals had a higher rate of unanticipated postoperative hospital admission (13%) than those treated in ASCs (0%) (P = .01). We found no differences with regard to postoperative complications, emergency department visits, readmission, rerupture, reoperation/revision, or death. Patients treated in hospitals had a higher mean (±SD) implant cost ($664 ± $810) than those treated in ASCs ($175 ± $585) (P < .01). We found no differences between settings with regard to total cost, supply costs, operating room charges, or anesthesia charges. Higher implant cost was associated with hospital setting (odds ratio = 16 [95% CI: 1.7-157]) and body mass index > 25 (odds ratio = 1.2 [95% CI: 1.0-1.5]). Operating room costs were strongly correlated with total costs (R2 = .94).

Conclusion

The overall cost and complication rate of ATRs were not significantly different between ASCs and hospitals. ATRs performed in hospitals had higher implant costs and higher rates of postoperative admission than those performed in ASCs.

Perceived barriers and facilitators of day-case surgery for major foot and ankle procedures? A cross-sectional survey of United Kingdom surgeons

BACKGROUND

Advances in minimally invasive surgery and improved post-operative pain management make it possible to consider performing even major foot/ankle operations as day-case. This could have significant benefits for patients and the health service. However there are theoretical concerns about post-operative complications and patient satisfaction due to pain.

AIM

To scope the current practice of foot and ankle surgeons on day-case surgery for major foot and ankle procedures in the United Kingdom (UK).

METHODS

An online survey (19 questions) was sent to UK foot and ankle surgeons via the British Orthopaedic Foot & Ankle Society membership list in August 2021. Major foot and ankle procedures were defined as surgery that is usually performed as an inpatient in majority of centres and day-case as same day discharge, with day surgery as the intended treatment pathway.

RESULTS

132 people responded to the survey invitation with 80% working in Acute NHS Trusts. Currently 45% of respondents perform less than 100 day-case surgeries per year for these procedures. 78% felt that there was scope to perform more procedures as day-case at their centre. Post-operative pain (34%) and patient satisfaction (10%) was not highly measured within their centres. Lack of adequate physiotherapy input pre/post-operatively (23%) and lack of out of hours support (21%) were the top perceived barriers to performing more major foot and ankle procedures as day-case.

CONCLUSION

There is consensus among UK surgeons to do more major foot/ankle procedures as day-case. Out of hours support and physiotherapy input pre/ post-op were perceived as the main barriers. Despite theoretical concerns about post-operative pain and satisfaction this was only measured by a third of those surveyed. There is a need for nationally agreed protocols to optimise the delivery of and measurement of outcomes in this type of surgery. At a local level, the provision of physiotherapy and out of hours support should be explored at sites where this is a perceived barrier.

An Updated Epidemiology of Foot and Ankle Fractures in the United States: Complications, Mechanisms, and Risk Factors

Foot and ankle fractures are prevalent emergent injuries, about which there remains a lack of in-depth epidemiological information. This analysis of the epidemiology of foot and ankle injuries in the United States updates a previously conducted study. Data from the National Trauma Data Bank (2012-2017) were used for analysis. Demographic variables, mechanism of injuries, and comorbidities were analyzed to determine risk factors for complications after foot and ankle injuries. Young adults aged 21 to 30 years had the highest injury rates; however, in general, older individuals were more at risk for complications. Black individuals were more at risk for certain complications, while Asians were at lower risk, when compared to White individuals. The comorbidities of bleeding disorders, diabetes, smoking, hypertension, and chronic obstructive pulmonary disease all increased risk of at least 1 complication. In terms of mechanism, traffic incidents were found to be the most strongly associated with complications.

An Evaluation of Patient Characteristics Associated With Medical Disposition in the Surgical Treatment of Ankle Fractures

The objective of this investigation was to evaluate patient characteristics associated with medical disposition in treatment of ankle fractures. The 2018 American College of Surgeons National Surgical Quality Improvement Program database was interrogated with data extracted related to the 6 current procedural terminology (CPT) codes available pertaining to ankle fractures: 27766, 27769, 27792, 27814, 27822, and 27823. The primary outcome analysis involved a comparison of patient characteristics and short-term adverse outcomes between those fractures repaired on an inpatient basis versus outpatient basis. A secondary analysis was then performed on patient characteristics and adverse short-term outcomes between those fractures treated on an inpatient basis who were discharged home versus elsewhere. Age (p < .001), race (p < .001), ethnicity (p < .001), body mass index (BMI) (p < .001), estimated probability of mortality (p < .001), estimated probability of morbidity (p < .001), CPT code of fracture designation (p < .001), functional status (p < .001), elective surgery designation (p < .001), American Society of Anesthesiologists class (p < .001), diabetes (p < .001), smoking status (p < .001), dyspnea (p < .001), COPD (p < .001), congestive heart failure (p < .001), hypertension (p < .001), dialysis (p < .001), cancer (p < .001), steroid use (p < .001), blood transfusion history (p < .001), and sepsis/systemic inflammatory response syndrome history (p < .001) were all independently associated with the ankle fracture repair being performed on an inpatient basis on regression analysis. Age (p < .001), race (p = .025), ethnicity (p < .001), BMI (p = .001), CPT code of fracture designation (p < .001), preoperative functional status (p < .001), and American Society of Anesthesiologists class (p < .001) were all independently associated with inpatient ankle fracture repairs being discharged to home following the procedure on regression analysis. The results of this investigation demonstrate that differences in patient demographic characteristics might contribute to medical decision-making as it relates to patient management and discharge disposition in the treatment of ankle fractures.

Comparison of outpatient vs. inpatient anatomic total shoulder arthroplasty: a propensity score–matched analysis of 20,035 procedures

Background

As the proportion of anatomic total shoulder arthroplasty (aTSA) operations performed at outpatient surgical sites continues to increase, it is important to evaluate the clinical implications of this evolution in care.

Methods

Patients who underwent TSA for glenohumeral osteoarthritis from 2007 to 2019 were identified in the American College of Surgeons National Surgical Quality Improvement Program registry. Demographic data and 30-day outcomes were collected, and patients were separated into inpatient and outpatient (defined as same day discharge) groups. To control for confounding variables, a propensity score–matching algorithm was utilized. Outcomes included 30-day adverse events, readmission, and operative time.

Results

A total of 20,035 patients who underwent aTSA between 2007 and 2019 were identified: 18,707 inpatient aTSAs and 1328 outpatient aTSAs. On matching, there were no significant differences in patient characteristics between inpatient and outpatient cohorts. Patients who underwent outpatient aTSA were less likely to experience a serious adverse event when compared with their matched inpatient aTSA counterparts (outpatient: 1.1% vs. inpatient: 2.1%, P = .03). Outpatient aTSA was associated with similar rates of all specific individual complications and readmissions (1.5% vs. 1.9%, P = .31).

Conclusion

When compared with a propensity score–matched cohort of inpatient counterparts, the present study found outpatient aTSA was associated with significantly reduced severe adverse events and similar readmission rates. These findings support the growing use of outpatient aTSA in appropriately selected patients.

Unplanned Emergency and Urgent Care Visits After Outpatient Orthopaedic Surgery

Introduction

This study sought to determine (1) incident risk, (2) chief report, (3) risk factors, and (4) total cost of unplanned healthcare visits to an emergency and/or urgent care (ED/UC) facility within 30 days of an outpatient orthopaedic procedure.

Methods

This was a retrospective database review of 5,550 outpatient surgical encounters from a large metropolitan healthcare system between 2012 and 2016. Statistical analysis consisted of measuring the ED/UC incident risk, respective to the procedures and anatomical region. Patient-specific risk factors were evaluated through multigroup comparative statistics.

Results

Of the 5,550 study patients, 297 (5.4%) presented to an ED/UC within 30 days of their index procedure, with 23 (0.4%) needing to be readmitted. Native English speakers, patients older than 45 years, and nonsmokers had significant reduced relative risk of unplanned ED or UC visit within 30 days of index procedure (P < 0.01). In addition, hand tendon repair/graft had the greatest risk incidence for ED/UC visit (11.0%). Unplanned ED/UC reimbursements totaled $146,357.34, averaging $575.65 per visit.

Discussion

This study provides an evaluation of outpatient orthopaedic procedures and their relationship to ED/UC visits. Specifically, this study identifies patient-related and procedural-related attributes that associate with an increased risk for unplanned healthcare utilization.

[Potential of inpatient cases of a university hospital for orthopedics and trauma surgery for outpatient care]

BACKGROUND

The act of the Medical Service of the Health Funds (MDK) is intended to shift health services previously provided in inpatient care to the outpatient care sector in accordance with § 115b SGB V. The aim of this study was the investigation of potential groups of inpatient cases of a university hospital for trauma surgery and orthopedics, which might be at risk for transfer to surgical outpatient treatment.

METHODS

Data collection using SAP Data Warehouse included all inpatient cases 2017-2019, with subgroup analysis of economic parameters of three risk groups (RG): 1) primary misallocation, 2) procedures of AOP categories 1 and/or 2 and 3) elective 1‑day cases. Furthermore, an analysis of epidemiological parameters and an economic evaluation were performed.

RESULTS

Primary misallocations related to 245 cases, RG 2 had 764 cases and RG 3 had 891 cases. The average age was 45.5 ± 17.7 years and in 90% there were no relevant comorbidities (PCCL 0). The majority of cases were assigned to DRG I23B and I21Z (removal of osteosynthesis material, 15-23%), followed by open or arthroscopic surgery of the extremities (DRG I32F, I32G, I24Z, I18B, 6-9%). In cases of a statutory shift of inpatient to outpatient surgical procedures, the potential loss of revenue in 2017 was € 1,049,207, in 2018 € 1,076,727 and in 2019 € 923,163.

CONCLUSION

Individual groups have an increased potential in certain DRGs for a shift from inpatient to outpatient surgical procedures and are at risk for relevant revenue reductions in the course of further expansion of outpatient care. Proactive patient management in terms of outpatient versus inpatient treatment and special management of staff and spatial resources are necessary to anticipate potential downstream revenue cuts.

Outpatient lower extremity fracture surgery: should we be concerned?

PURPOSE

With rising healthcare costs and insurance push against non-emergent hospital admission, lower extremity fracture treatment is shifting toward outpatient procedures over inpatient hospitalizations. This study compares outcomes for fractures treated as inpatient versus outpatient.

METHODS

We conducted a retrospective review of lower extremity fracture patients. We collected demographics, injury information, hospital course, and complication data. Length of stay was categorized as "inpatient" and "outpatient" based a 24-h hospital stay cutoff. Data analysis included differences between cohorts with regards to readmissions and complications.

RESULTS

We identified 229 patients who met inclusion criteria. Inpatient versus outpatient status was predictive of in-hospital complications; however, inpatient versus outpatient status did not predict 1-year readmission.

CONCLUSION

Outpatient surgery is safe and effective. As the population increases and ages, low-risk surgeries should be considered for outpatient rather than inpatient stays to lower costs, save resources, and reduce complications.

Octogenarian and Nonagenarians Are at a Higher Risk for Experiencing Adverse 30-Day Outcomes Following ORIF of Ankle Fractures

Introduction:

Despite an increasing number of elderly individuals undergoing surgical fixation for ankle fractures, few studies have investigated peri-operative outcomes and safety of surgery in an octogenarian and nonagenarian population (age >80 years).

Materials and Methods:

The 2012-2017 American College of Surgeons database was queried for patients undergoing open reduction internal fixation for isolated uni-malleolar, bi-malleolar and tri-malleolar ankle fractures. The study cohort was divided into 3 comparison groups (age <65 years, 65-75 and >80). Multi-variate regression analyzes were used to compare the independent effect of varying age groups on 30-day post-operative outcomes while controlling for baseline clinical characteristics and co-morbidity burdens.

Results:

A total of 19,585 patients were included: 5.3% were >80 years, 18.1% were 65-79 years, and 76.6% were <65 years. When compared to the non-geriatric population, individuals >80 years were at a significantly Abstract: higher risk of 30-day wound complications (OR 1.84; p = 0.019), pulmonary complications (OR 3.88; p < 0.001), renal complications (OR 1.96; p = 0.015), septic complications (OR 3.72; p = 0.002), urinary tract infections (OR 2.24; p < 0.001), bleeding requiring transfusion (OR 1.90; p = 0.025), mortality (or 7.44; p < 0.001), readmissions (OR 1.65; p = 0.004) and non-home discharge (OR 13.91; p < 0.001).

Discussion:

Octogenarians undergoing ankle fracture fixation are a high-risk population in need of significant pre-operative surgical and medical optimization. With the majority of patients undergoing non-elective ORIF procedures, it is critical to anticipate potential complications and incorporate experienced geriatric providers early in the surgical management of these patients.

Conclusions:

Octogenarians and nonagenarians are fundamentally distinct and vulnerable age groups with a high risk of complications, readmissions, mortality and non-home discharges compared to other geriatric (65-79 years) and non-geriatric (<65 years) patients. Pre-operative counseling and risk-stratification are essential in this vulnerable patient population.
