What factors influence follow-up in orthopedic trauma surgery?

Risk Factors for Loss to Follow-up of Elderly Patients After Hip Fracture Surgery: A Retrospective Cohort Study

Introduction

Non-attendance with scheduled postoperative follow-up visits remains a common issue in orthopaedic clinical research. The objective of this study was to identify the risk factors associated with loss to follow-up among elderly patients with hip-fracture postoperatively.

Methods

A retrospective analysis of 1-year post-surgery was performed on patients aged over 60 years who underwent hip-fracture surgery from January 2017 to March 2019. Based on their completion of the appointed follow-up schedule, the patients were classified into 2 groups: the Loss to Follow-up (LTFU) Group and the Follow-up (FU) Group. Clinical outcomes were evaluated by Functional Recovery Score (FRS) questionnaires. Telephone interviews were conducted with patients lost to follow-up to determine the reasons for non-attendance. A comparative analysis of baseline characteristics between the 2 groups was implemented, with further exploration of statistical differences through logistic regression.

Results

A total of 992 patients met the inclusion criteria were included in this study, of which 189 patients, accounting for 19.1%, were lost to follow-up 1 year postoperatively. The mean age of the patients in the LTFU Group was 82.0 years, significantly higher than the 76.0 years observed in the FU Group (P < 0.001). The FRS for the LTFU Group was marginally higher than that of the FU group (84.0 vs 81.0), with no significant difference (P = 0.060). Logistic regression analysis identified several significant predictors of noncompliance, including advanced age at surgery, femoral neck fracture, hip arthroplasty, long distance from residence to hospital, and the reliance on urban-rural public transportation for reaching the hospital.

Conclusion

Postoperative follow-up loss was prevalent among elderly patients with hip fractures. Our study indicated a constellation of risk factors contributing to noncompliance, including advanced age, transportation difficulties, long travel distance, femoral neck fracture and hip arthroplasty surgery.

Improving Patient Recall Following Operative Orthopaedic Trauma

BACKGROUND

Orthopaedic trauma patients may experience poor recall regarding their injury and treatment, impairing postoperative outcomes. We sought to evaluate the impact of a standardized postoperative educational protocol on patient recall, adherence to the treatment plan, and satisfaction.

METHODS

Two hundred and twenty adult, English-speaking patients with surgically treated lower-extremity fractures were prospectively included. One hundred and ten patients in the educational intervention cohort met with a non-physician study member after surgery but before hospital discharge. They were given a written questionnaire evaluating knowledge of key aspects of their injury and treatment plan. For incorrectly answered questions, the study team member told the patient the correct answer (e.g., "No, you broke your tibia."). Immediately after, the patient was verbally asked the question again (e.g., "Which bone did you break?"), repeating the process until the answer was correct. The 110 patients in the control cohort did not receive this "teach-back" protocol. During their first postoperative appointment, all 220 patients completed a follow-up questionnaire assessing recall, adherence to the treatment plan, and satisfaction.

RESULTS

The control cohort correctly answered 64% of recall-oriented questions versus 89% in the intervention cohort (p < 0.001). Eighty-two percent of control patients versus 89% patients in the intervention cohort adhered to postoperative weight-bearing restrictions (p = 0.09). Eighty-four percent of controls adhered to their deep venous thrombosis prophylaxis regimen versus 99% of the intervention cohort (p < 0.001). On a 5-point Likert scale, controls were less satisfied with their overall orthopaedic care compared with patients in the intervention cohort (mean of 4.38 ± 0.84 versus 4.54 ± 0.63 points; p = 0.02), although this difference was less than the minimal clinically relevant difference of 10% that was defined at study onset. On propensity score-weighted multivariable analysis, receipt of the postoperative educational intervention was the only modifiable factor associated with improvement in patient recall (26% improvement [95% confidence interval, 20% to 31%]; p < 0.001).

CONCLUSIONS

Some orthopaedic trauma patients' nonadherence to surgeon recommendations and dissatisfaction with care may be mitigated by postoperative education. This standardized postoperative educational protocol improves orthopaedic trauma patients' recall, adherence to their treatment plan, and satisfaction in a manner requiring minimal time.

Professionalism in Hand Surgery: Treating the Noncompliant Patient

Every practicing hand surgeon has had the challenging experience of treating a patient who demonstrates difficulty with, or inability to comply with medical advice. Patient noncompliance can lead to not only poor patient outcomes but also deterioration in the therapeutic relationship, physician burnout, high cost of care, and medical-legal risk. The guiding principles in the ethical practice of medicine render it important to consider noncompliance as a potentially modifiable risk factor, and every attempt should be made to work with these noncompliant patients to achieve the best possible outcomes. Data suggest that noncompliance may be affected by socioeconomic status and race; many of these patients are among the vulnerable. However, in some instances, treatment options may warrant alteration or adjustment to reflect the noncompliance of the patient. Rarely, it may be reasonable for a physician to discharge a patient from care once any urgent problems have been managed. Ethical and responsible management of a noncompliant patient requires a thoughtful and measured approach.

A comparison of the psychometric properties of a person-administered vs. automated screening tool for posttraumatic stress disorder (PTSD) in traumatically injured patients

BACKGROUND

The American College of Surgeons Committee on Trauma (ACS-CoT) mandated that trauma centers have mental health screening and referral protocols in place by 2023. This study compares the Injured Trauma Survivor Screen (ITSS) and the Automated Electronic Medical Record (EMR) Screen to assess their performance in predicting risk for posttraumatic stress disorder (PTSD) within the same sample of trauma patients to inform trauma centers' decision when selecting a tool to best fit their current clinical practice.

METHODS

This was a secondary analysis of three prospective cohort studies of traumatically injured patients (N = 255). The ITSS and Automated EMR Screen were compared using receiver operating characteristic curves to predict risk of subsequent PTSD development. PTSD diagnosis at 6-month follow-up was assessed using the Clinician Administered PTSD Scale for DSM-5.

RESULTS

Just over half the sample screened positive on the ITSS (57.7%), while 67.8% screened positive on the Automated EMR Screen. The area under the curve (AUC) for the two screens was not significantly different (ITSS AUC = 0.745 versus Automated EMR Screen AUC = 0.694, p = 0.21), similar performance in PTSD risk predication within the same general trauma population. The ITSS and Automated EMR Screen had similar sensitivities (86.5%, 89.2%), and specificities (52.5%, 40.9%) respectively at their recommended cut-off points.

CONCLUSION

Both screens are psychometrically comparable. Therefore, trauma centers considering screening tools for PTSD risk to comply with the ACS-CoT 2023 mandate should consider their local resources and patient population. Regardless of screen selection, screening must be accompanied by a referral process to address the identified risk.

Medicaid Insurance Is Associated With More Complications and Emergency Department Visits but Equivalent 5-Year Secondary Surgery Rate After Primary Hip Arthroscopy

PURPOSE

To compare 90-day complications, 30-day emergency department (ED) visits, and 5-year rate of secondary surgeries for patients with Medicaid vs commercial insurance undergoing primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and/or labral tears using a large national database.

METHODS

The PearlDiver Mariner151 database was used to identify patients with International Classification of Diseases, Tenth Revision diagnosis codes for FAIS and/or labral tear who underwent primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021. Patients with Medicaid were matched 1:4 to a control group of commercially insured patients based on age, sex, body mass index, and Elixhauser Comorbidity Index. Rates of 90-day complications and 30-day ED visits were compared using multivariate regression models. Five-year rates of secondary surgeries-revision arthroscopy or total hip arthroplasty-were compared between cohorts by Kaplan-Meier analysis.

RESULTS

A total of 2,033 Medicaid patients were matched with 8,056 commercially insured patients. Rates of adverse events were low; however, Medicaid patients were significantly more likely than commercially insured patients to experience any 90-day complication (2.12% vs 1.43%; odds ratio [OR], 1.2; P = .02). Medicaid patients also experienced more 30-day ED visits than commercially insured patients (8.61% vs 4.28%), and on multivariate logistic regression, insurance status was the strongest determinant of 30-day ED visits (relative to commercial, Medicaid OR, 2.02; P < .001). Despite these differences, 5-year rates of secondary surgeries were comparable between groups (6.1% vs 6.0%; P = .6).

CONCLUSIONS

In this large national database study, Medicaid patients undergoing primary hip arthroscopy showed significantly greater odds of experiencing 90-day postoperative complications and 30-day ED visits compared to commercially insured patients. Nevertheless, both groups had similar survivorship rates at 5-year follow-up, similar to prior estimates irrespective of insurance. These results document encouraging secondary surgery rates in Medicaid patients.

Effects of Travel Distance on Complications and Outcomes in Total Ankle Arthroplasty

Owing to the last decade's increase in the number of total ankle arthroplasty (TAA) procedures performed annually, there is a concern that the disproportionate distribution of orthopaedic surgeons who regularly perform TAA may impact complications and/or patient satisfaction. This study examines patient-reported outcomes and complications in TAA patients who had to travel for surgery compared to those treated locally. This is a single-center retrospective review of 160 patients undergoing primary TAA between January 2016 and December 2018, with mean age 65 (range: 59-71) years, mean body mass index (BMI) 28.7 kg/m2, 69 (43.1%) females, and mean 1.5 (SD = 0.51) years follow-up. Patients were grouped by distance traveled (<50 miles [n = 89] versus >50 miles traveled [n = 71]). There were no significant differences in rate or type of postoperative complications between the <50 mile group (16.9%) and the >50 mile group (22.5%) (P = .277). Similarly, there were no significant difference in postoperative PROMIS scores between the groups (P = .858). Given uneven distribution of high-volume surgeons performing TAA, this is important for patients who are deciding where to have their TAA surgery and for surgeons on how to counsel patients regarding risks when traveling longer distances for TAA care.Levels of Evidence: Level III: Retrospective Cohort Study.

Socioeconomic status is associated with greater hazard of post-discharge mortality than race, gender, and ballistic injury mechanism in a young, healthy, orthopedic trauma population

OBJECTIVES

To explore the utility of legacy demographic factors and ballistic injury mechanism relative to popular markers of socioeconomic status as prognostic indicators of 10-year mortality following hospital discharge in a young, healthy patient population with isolated orthopedic trauma injuries.

METHODS

A retrospective cohort study was performed to evaluate patients treated at an urban Level I trauma center from January 1, 2003, through December 31, 2016. Current Procedure Terminology (CPT) codes were used to identify upper and lower extremity fracture patients undergoing operative fixation. Exclusion criteria were selected to yield a patient population of isolated extremity trauma in young, otherwise healthy individuals between the ages of 18 and 65 years. Variables collected included injury mechanism, age, race, gender, behavior risk factors, Area Deprivation Index (ADI), and insurance status. The primary outcome was post-discharge mortality, occurring at any point during the study period.

RESULTS

We identified 2539 patients with operatively treated isolated extremity fractures. The lowest two quartiles of socioeconomic status (SES) were associated with higher hazard of mortality than the highest SES quartile in multivariable analysis (Quartile 3 HR: 2.2, 95% CI: 1.2-4.1, p = 0.01; Quartile 4 HR: 2.2, 95% CI: 1.1-4.3, p = 0.02). Not having private insurance was associated with higher mortality hazard in multivariable analysis (HR 2.0, 95% CI: 1.3-3.2, p = 0.002). The presence of any behavioral risk factor was associated with higher mortality hazard in univariable analysis (HR: 1.8, p < 0.05), but this difference did not reach statistical significance in multivariable analysis (HR: 1.4, 95%: 0.8-2.3, p = 0.20). Injury mechanism (ballistic versus blunt), gender, and race were not associated with increased hazard of mortality (p > 0.20).

CONCLUSION

Low SES is associated with a greater hazard of long-term mortality than ballistic injury mechanism, race, gender, and medically diagnosable behavioral risk factors in a young, healthy orthopedic trauma population with isolated extremity injury.

Factors Influencing Compliance to Follow-up Visits in Orthopaedic Surgery

BACKGROUND

Orthopaedic procedures require postoperative follow-up to maximize recovery. Missed appointments and noncompliance can result in complications and increased healthcare costs. This study investigates the relationship between patient postoperative visit attendance and the distance traveled to receive care.

MATERIALS AND METHODS

A retrospective review of all surgeries performed by a single orthopaedic surgeon in 2019 at level 1 trauma center in a midsized city serving a largely rural population was completed. We excluded patients who underwent another subsequent procedure. Distance to care and time traveled were determined by the patient's address and the clinic address using Google Maps Application Programming Interface. Other variables that may affect attendance at follow-up visits were also collected. Univariate and multivariate logistic regression was done with purposeful selection.

RESULTS

We identified 518 patients of whom 32 (6%) did not attend their first scheduled follow-up appointment. An additional 47 (10%) did not attend their second follow-up. In total, 79 patients (15%) did not attend one of their appointments. Younger age, male sex, Black or African American race, self-pay, Medicaid insurance, accident insurance, and increased distance were individual predictors of missing an appointment. In the final multivariate logistic regression model, male sex (OR 1.74), Black or African American race (OR 2.78), self-pay (OR 3.12), Medicaid (OR 3.05), and traveling more than 70 miles to clinic (OR 2.02) markedly predicted missing an appointment, while workers' compensation (OR 0.23) predicted attendance.

DISCUSSION

Several nonmodifiable patient factors predict patient noncompliance in attending orthopaedic postoperative visits. When patients are considered at high risk of being lost to follow-up, there may be an opportunity to implement interventions to improve follow-up rate and patient outcomes, minimize patient costs, and maximize profitability for the hospital.

Missed Short-term Follow-up After Arthroscopic Rotator Cuff Surgery: Analysis of Surgical and Demographic Factors

INTRODUCTION

Few current studies have examined loss to follow-up after rotator cuff-related shoulder arthroscopy. Understanding the demographic and surgical factors for missed follow-up would help identify patients most at risk and potentially mitigate the onset of complications while maximizing clinical outcomes.

METHODS

A retrospective review of consecutive rotator cuff arthroscopic procedures with a minimum of 12-month follow-up done by a single, fellowship-trained surgeon was undertaken from February 2016 through January 2022. Demographic patient and surgical data, including age, sex, marital status, self-identified race, and body mass index, were collected. Follow-up at ≤3, 6 weeks, 3, 6, and 12 months was determined. Patient-related and surgical predictors for missed short-term follow-up, defined as nonattendance at the 6 and 12-month postoperative visits, were identified.

RESULTS

There were 449 cases included, of which 248 (55%) were women. The median age was 57 years (interquartile range [IQR], 51 to 62). Patients with commercial insurance (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.23 to 0.64; P < 0.001) or workers' compensation (OR, 0.15; 95% CI, 0.05 to 0.43; P < 0.001) were less likely to miss the 6-month follow-up compared with patients with Medicare, whereas increased socioeconomic deprivation (OR, 0.86; 95% CI, 0.77 to 0.97, P = 0.015) was associated with decreased odds of missing that visit. Patients who missed the ≤3 weeks (OR, 1.77; 95% CI, 1.14 to 2.74, P = 0.010) and 3-month (OR, 8.55; 95% CI, 4.33 to 16.86; P < 0.001) follow-ups were more likely to miss the 6-month follow-up. Use of a patient contact system (OR, 0.55; 95% CI, 0.35 to 0.87, P = 0.01) and increased number of preoperative visits (OR, 0.91; 95% CI, 0.84 to 0.99, P = 0.033) were associated with decreased odds of missing the 12-month follow-up. Patients who missed the 6-month follow-up were more likely to miss the 12-month follow-up (OR, 5.38; 95% CI, 3.45 to 8.40; P < 0.001).

CONCLUSION

Implementing an electronic patient contact system while increasing focus on patients with few preoperative visits and who miss the 6-month follow-up can reduce the risk of missed follow-up at 12 months after shoulder arthroscopy.

Telemedicine Improves Access to Care for Spine Patients With Low Socioeconomic Status

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

The objective of this study is to compare the likelihood of missing a scheduled telemedicine and in-person appointments for spine patients. The secondary objective is to assess the impact of socioeconomic status on missed telemedicine and in-person appointments.

METHODS

Patients with scheduled outpatient appointments with orthopedic spine faculty between 2019 and 2021 were divided by appointment type: telemedicine (N = 4,387) and in-person (N = 3810). Socioeconomic status was assessed using Area Deprivation Index (ADI) stratified based on percentile: low (<25), medium (25-75), and high (>75) levels of socioeconomic disadvantage. The primary outcome measure was missed clinic appointments, which was defined as having at least one appointment that was cancelled or labeled "no show."

RESULTS

Patients with in-person appointments missed appointments more often than patients with telemedicine visits (51.3% vs 24.7%, P < .001). Patients with high ADI missed their in-person appointments more often than patients with medium and low ADI (59.5% vs 52.2% and 47.5%, P < .001). There was no difference in missed telemedicine visits between patients with high, medium, and low ADI (27.6% vs 24.8% vs 23.8%, P = .294). Patients that missed an appointment were 41.9% more likely to be high ADI (OR 1.42, 95% CI 1.20-1.68, P < .001) and 13.4% more likely to be medium ADI (OR 1.13, 95% CI 1.03-1.26, P = .015) compared with low ADI patients.

CONCLUSIONS

Telemedicine may serve a role in reducing disparity in appointment attendance. While further studies are needed to validate these findings, spine surgeons should consider offering telemedicine as an option to patients.

Follow-up non-attendance after long-bone fractures in a low-resource setting: a prospective study of predictors and interventions to increase attendance rates

BACKGROUND

While the majority of traumatic injuries occur in low- and middle-income countries, the published literature comes chiefly from high-income countries due to poor follow-up. Clinical and radiographic post-surgical trauma follow-up is essential to high-quality research and objective monitoring for healing and/or complications. This study aimed to identify the predictors of follow-up non-attendance in a low-resource setting and investigate the extent to which interventional efforts based on mobile phone technology (MPT) and home visits improved the follow-up rates for fractures treated with SIGN nails.

METHODS

This was a prospective study of 594 patients with long-bone fractures. Socio-demographic (e.g. age, gender, marital status, education level, etc.) and clinical (e.g. fracture type, concomitant injuries, comorbidity, etc.) data were collected on each patient. Before discharge, the importance of follow-up was explained to patients and their relations. They were encouraged to attend even if they felt well. Their residential addresses and telephone numbers were validated and securely stored. Patients who missed their appointments were contacted by phone. Those who failed to honour 2 or 3 rescheduled appointments were visited in their home. The patients were divided into those who returned for the primarily scheduled follow-up without prompting (volition group) and those who did not come (non-attenders). Univariate analyses and binary logistic regression were conducted to determine the significant predictors of non-attendance.

RESULTS

The proportion of patients in the volition group reduced from 96.1% at 6 weeks to 53.0% at 12 weeks and 39.2% at 6 months. However, interventional efforts increased these values to 98.5%, 92.5%, and 72.4% respectively. Walking unaided before the primarily scheduled 12-week appointment was the major reason for not attending the follow-up. Education, occupation, post-operative length of hospital stay (PLOS) and infection were significantly associated with non-attendance but younger age, long distances from the hospital, being separated or divorced, difficulty paying the in-patient care bill, closed fracture, having no (or a non-limb) concomitant injury, achieving painless weight bearing ≤ 6 weeks post-operatively and needing no additional surgery were independent predictors of non-attendance.

CONCLUSIONS

Our study sheds light on the predictors of follow-up non-attendance and demonstrates how interventional efforts improved attendance rates in a low-resource setting. In addition, efforts that better the socio-economic status of people such as more-encompassing health insurance coverage and greater work flexibility can improve the follow-up attendance rates.

Patient Adherence Following Knee Surgery: Evidence-Based Practices to Equip Patients for Success

Patient adherence with postoperative wound care, activity restrictions, rehabilitation, medication, and follow-up protocols is paramount to achieving optimal outcomes following knee surgery. However, the ability to adhere to prescribed postoperative protocols is dependent on multiple factors both in and out of the patient's control. The goals of this review article are (1) to outline key factors contributing to patient nonadherence with treatment protocols following knee surgery and (2) to synthesize current management strategies and tools for optimizing patient adherence in order to facilitate efficient and effective implementation by orthopaedic health care teams. Patient adherence is commonly impacted by both modifiable and nonmodifiable factors, including health literacy, social determinants of health, patient fear/stigma associated with nonadherence, surgical indication (elective vs. traumatic), and distrust of physicians or the health care system. In addition, health care team factors, such as poor communication strategies or failure to follow internal protocols, and health system factors, such as prior authorization delays, staffing shortages, or complex record management systems, impact patient's ability to be adherent. Because the majority of factors found to impact patient adherence are nonmodifiable, it is paramount that health care teams adjust to better equip patients for success. For health care teams to successfully optimize patient adherence, focus should be paid to education strategies, individualized protocols that consider patient enablers and barriers to adherence, and consistent communication methodologies for both team and patient-facing communication.

Post-Trauma Discharge Instructions: Are We Dropping the Ball?

INTRODUCTION

Complex follow-up plans for polytrauma patients are compiled at the end of hospitalization into discharge instructions. We sought to identify how often patient discharge instructions incorrectly communicated specialist recommendations. We hypothesized that patients with more complex hospitalizations would have more discharge instruction errors (DI-errors).

METHODS

We reviewed adult trauma inpatients (March 2017-March 2018), excluding those who left against medical advice or were expected to follow up outside our system. Complex hospitalizations were represented using injury severity (ISS), hospital length of stay (LOS), intensive care unit length of stay (iLOS), and number of consultants (NC). We recorded the type of consultant (surgical or nonsurgical), and consultant recommendations for follow-up. DI-errors were defined as either follow-up necessary but omitted or follow-up not necessary yet present on the instructions. Patients with DI-errors were compared to patients without DI-errors. Groups were compared using Wilcoxon rank sum or chi-square (alpha <.05).

RESULTS

We included 392 patients (median age 45 [IQR 26-58], ISS 14 [10-21], LOS 6 [3-11]). 55 patients (14%) had DI-errors. Factors associated with DI-errors included the total number of consultants and use of nonsurgical consultants. ISS, LOS, iLOS, were not associated with DI-errors.

CONCLUSION

Common measures of admission complexity were not associated with DI-errors, although the number and type of consultants were associated with DI-errors. Non-surgical specialty consultant recommendations were more likely to be omitted. It is crucial for patients to receive accurate discharge instructions, and systematic processes are needed to improve communication with the patients at discharge.

Return to Skiing After Tibial Plateau Fracture

Background

Tibial plateau fractures in skiers are devastating injuries with increasing incidence. Few studies have evaluated patient-reported outcomes and return to skiing after operative fixation of a tibial plateau fracture.

Purpose

To (1) identify demographic factors, fracture characteristics, and patient-reported outcome measures that are associated with return to skiing and (2) characterize changes in skiing performance after operative fixation of a tibial plateau fracture.

Study Design

Case series; Level of evidence, 4.

Methods

We reviewed all operative tibial plateau fractures performed between 2016 and 2021 at a single level-1 trauma center. Patients with a minimum of 10-month follow-up data were included. Patients who self-identified as skiers or were injured skiing were divided into those who returned to skiing and those who did not postoperatively. Patients were contacted to complete the Patient-Reported Outcomes Measurement Information System-Physical Function domain (PROMIS-PF), the Knee injury and Osteoarthritis Outcome Score-Activities of Living (KOOS-ADL), and a custom return-to-skiing questionnaire. Multivariate logistic regression was performed with sex, injury while skiing, PROMIS-PF, and KOOS-ADL as covariates to evaluate factors predictive of return to skiing.

Results

A total of 90 skiers with a mean follow-up of 3.4 ± 1.5 years were included in the analysis. The rate of return to skiing was 45.6% (n = 41). The return cohort was significantly more likely to be men (66% vs 41%; P = .018) and injured while skiing (63% vs 39%; P = .020). In the return cohort, 51.2% returned to skiing 12 months postoperatively. The percentage of patients who self-reported skiing on expert terrain dropped by half from pre- to postinjury (61% vs 29.3%, respectively). Only 78% of return skiers had regained comfort with skiing at the final follow-up. Most patients (65%) felt the hardest aspect of returning to skiing was psychological. In the multivariate regression, the male sex and KOOS-ADL independently predicted return to skiing (P = .006 and P = .028, respectively).

Conclusion

Fewer than half of skiers who underwent operative fixation of a tibial plateau fracture could return to skiing at a mean 3-year follow-up. The knee-specific KOOS-ADL outperformed the global PROMIS-PF in predicting a return to skiing.

Effects of Patient Assessment and Education by an Integrated Care Team on Postoperative Adherence and Failure Rates After Osteochondral Allograft and Meniscal Allograft Transplantation in the Knee

Background

Patient nonadherence with prescribed rehabilitation protocols is associated with up to 16 times higher likelihood of treatment failure after osteochondral allograft transplantation (OCA) and meniscal allograft transplantation.

Hypothesis

Patients who completed counseling with an orthopaedic health behavior psychologist as part of an evidence-based shift in practice at our institution would have significantly lower rates of nonadherence and surgical treatment failure versus patients who did not participate in counseling.

Study Design

Cohort study; Level of evidence, 2.

Methods

Patients in a prospective registry who underwent OCA and/or meniscal allograft transplantation between January 2016 and April 2021 were included for analysis when 1-year follow-up data were available. Of 292 potential patients, 213 were eligible for inclusion. Patients were categorized based on whether they participated in the preoperative counseling and postoperative patient management program: no health psych group (n = 172) versus health psych group (n = 41). Nonadherence was defined as documented evidence of a deviation from the prescribed postoperative rehabilitation protocol.

Results

In this cohort of patients, 50 (23.5%) were documented to be nonadherent. Patients in the no health psych cohort were significantly more likely to be nonadherent (P = .023; odds ratio [OR], 3.4). Tobacco use (OR, 7.9), higher preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference score, lower preoperative PROMIS Mental Health score, older age, and higher body mass index were also significantly associated with nonadherence (P < .001 for all). Patients who were nonadherent with the prescribed postoperative rehabilitation protocol during the first year after transplantation were 3 times more likely (P = .004) to experience surgical treatment failure than those who were adherent. Overall, 26.2% of patients in the no health psych group experienced surgical treatment failure versus 12.2% in the health psych cohort.

Conclusion

Data from the present study suggest that preoperative counseling with a health behavior psychologist is associated with an improved rate of patient adherence and a lower proportion of surgical treatment failure after OCA and meniscal allograft transplantation. Patients who remained adherent to the postoperative protocol were 3 times more likely to have a successful short-term (≥1 year) outcome.

Orthopaedic trauma patient non-adherence to follow-up visits at a level 1 trauma center serving an urban and rural population

OBJECTIVE

To assess key demographic and psychosocial variables that may be associated with non-adherence to clinic visits following orthopaedic trauma injuries to patients in an urban and rural population.

METHODS

This retrospective review included all operative and non-operative patients presenting to a Level I academic trauma center serving an urban and rural population in the Midwest following an orthopaedic injury. The study tracked patient attendance to scheduled orthopaedic trauma follow-up clinic visits after a scheduled visit in the clinic following a trauma-related injury.

RESULTS

Data were obtained for 5816 unique orthopaedic trauma patients who had 21,066 post-treatment follow-up visits scheduled. 1627 "no-show" appointments were recorded. Factors associated with no-shows included male sex, age between 26 and 35 years, self-reported race other than white, employment listed as disabled, household income below $25,000, education less than a high school level, uninsured, Medicaid insured, and relationship status reported as single.

CONCLUSIONS

In the present study, key demographic and psychosocial factors were significantly associated with patient adherence to scheduled follow-up appointments after treatment for orthopaedic trauma. Identifying patients at higher risk for nonadherence will allow healthcare teams to educate patients, providers, and staff, link patients to resources to enhance adherence, and work with their institutions to develop and implement protocols for improving adherence to follow-up appointments.

Initial Outcomes After Unicompartmental Tibiofemoral Bipolar Osteochondral and Meniscal Allograft Transplantation in the Knee Using MOPS-Preserved Fresh (Viable) Tissues

BACKGROUND

Unicompartmental tibiofemoral bipolar osteochondral allograft transplantation (OCAT) with meniscal allograft transplantation (MAT) has not historically been associated with consistently successful outcomes for treatment of knee articular cartilage defects with meniscal deficiency.

HYPOTHESIS

Primary OCAT and MAT using fresh tissues will be associated with successful short-term outcomes based on statistically significant and clinically meaningful improvements in pain and function in the majority of patients.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Patients were prospectively enrolled into a registry for outcomes after OCAT and MAT. Patients included those who underwent primary OCAT and MAT using Missouri Osteochondral Preservation System (MOPS)-preserved allografts for treatment of large bipolar tibiofemoral articular cartilage defects with meniscal deficiency and had a minimum of 2-year follow-up data.

RESULTS

A total of 76 patients (n = 52 male; 68%) met inclusion criteria (mean follow-up, 52 months). The mean age was 41.1 years (range, 15-69 years), and the mean body mass index was 28.9 (range, 17-46); 48 patients underwent another OCAT in addition to the unicompartmental bipolar tibiofemoral OCAT and MAT; 23 patients (30.3%) were documented to be nonadherent to the prescribed postoperative restriction and rehabilitation protocol. The initial success rate (>2 years) was 77.6%, with 8 patients (10.5%) undergoing revision and 9 (11.8%) converting to arthroplasty. Variables associated with an increased risk for treatment failure (revision or arthroplasty) included ipsilateral osteotomy (P = .046; odds ratio [OR] = 3.3), ipsilateral concurrent procedure (P = .0057; OR = 5.5), and nonadherence (P = .0009; OR = 7.2). None of the patients undergoing revision surgery required arthroplasty at the time of data analysis such that the overall success rate for primary and revision unicompartmental bipolar OCA plus MAT was 88.2%. There were statistically significant (P < .0001) and clinically important improvements for all patient-reported outcomes at each annual follow-up time point.

CONCLUSION

Unicompartmental tibiofemoral bipolar OCAT and MAT can result in successful short-term outcomes (2-6 years) and satisfaction in the majority of patients (78%). Primary MOPS-preserved OCAT with MAT for treatment of femoral condyle and tibial plateau articular cartilage defects with concurrent meniscal deficiency was associated with statistically significant and clinically meaningful improvements in patient-reported measures of pain and function.

Factors Associated With Loss to Follow-up During the First Year After Total Knee Arthroplasty

Despite increased pressure to capture patient-reported outcome measures for at least 1 year following total joint arthroplasty (TJA), follow-up rates during the first year after TJA are typically lower than desired and may result in biased findings if data are not missing at random. We conducted a retrospective review of medical records of primary total knee arthroplasty patients treated by a single surgeon at an urban academic private hospital. Main measures were demographics (sex, age, race, and insurance), body mass index, travel distance to clinic, and the Knee Injury and Osteoarthritis Outcome Score (KOOS). Multivariable regression analyses were performed to identify patient characteristics associated with attendance at follow-up visits and predictors of attendance at 6-month follow-up. Among the 205 study patients, follow-up visit attendance declined from a high of 95.7% at day 14 to lows of 69.2% at 6 months and 64.4% at 1 year. Attendance at the previously scheduled follow-up visit was a statistically significant predictor of attendance at 3-month (P=.0015), 6-month (P=.0002), and 1-year (P<.0001) follow-up visits, and travel distance was significantly associated with attending the 1-year follow-up visit (P=.042). Patients with the most favorable KOOS Symptom, Pain, and Function in daily living subscale scores at 3-month follow-up were significantly less likely to attend the 6-month follow-up visit than patients with the least favorable KOOS scores. Prospective studies are needed to identify the full range of factors that may contribute to high rates of loss to follow-up after TJA, which should be of concern to researchers, clinicians, and hospitals.

Feasibility of Capturing Orthopaedic Trauma Research Outcomes Using Personal Mobile Devices

INTRODUCTION

Patients with orthopaedic trauma are frequently lost to follow-up. Personal mobile devices have been used to ascertain clinical research outcomes. The prevalence of mobile device ownership, use patterns, and attitudes about research among patients with orthopaedic trauma would inform clinical research strategies in this population.

METHODS

A total of 1,434 consecutive unique adults scheduled for an orthopaedic trauma outpatient clinic from December 2019 through February 2020 at a metropolitan level 1 trauma center were identified. Associations of demographic data with clinic attendance and mobile phone registration were explored by logistic regression. One hundred one patients attending clinic were then prospectively surveyed from June 2021 through August 2021 about housing stability, personal mobile device ownership, capabilities, use patterns, and openness to communicating via the device with for orthopaedic care and research.

RESULTS

The prevalence of personal mobile device ownership was 91% by registration data and 90% by a survey. Ninety-nine percent of survey respondents with mobile devices reported cell service always or most of the time. Ninety-three percent kept their devices charged always or most of the time. Ninety-two percent reported e-mail access. Eighty-three percent reported video capability. Ninety-one percent would communicate with their orthopaedic trauma care team by text message. Eighty-seven percent would answer research questions by phone call, 79% by text, and 61% by video. Eighty-five percent reported stable housing, which was not associated with mobile device ownership or use, but was associated with clinic nonattendance (29% vs. 66%, P < 0.01) and changing phone number at least once in the previous year (28% vs. 58%, P = 0.04).

DISCUSSION

Personal mobile devices represent a feasible platform for screening and collecting outcomes from patients with orthopaedic trauma. Nine in 10 patients own personal mobile devices, keep them charged, have text and e-mail service, and would use the device to participate in research. Housing instability was not associated with mobile device ownership or use patterns.

Clinic follow-up of orthopaedic trauma patients during and after the post-surgical global period: a retrospective cohort study

BACKGROUND

Insurance status is important as medical expenses may decrease the likelihood of follow-up after musculoskeletal trauma, especially for low-income populations. However, it is unknown what insurance factors are associated with follow-up care. In this study, we assessed the association between insurance plan benefits, the end of the post-surgical global period, and follow-up after musculoskeletal injury.

METHODS

This is a retrospective cohort study of 394 patients with isolated extremity fractures who were treated at three level-I trauma centers over four months in 2018. Paired t-tests were utilized to assess the likelihood of follow-up in relation to the 90-day post-surgical global period. Regression analysis was used to assess factors associated with the likelihood of follow-up. Supervised machine learning algorithms were used to develop predictive models of follow-up after the post-surgical global period.

RESULTS

Our final analysis included 328 patients. Likelihood of follow-up did not significantly change while within the post-surgical global period. When comparing follow-up within and outside of the post-surgical global period, there was a 20.1% decrease in follow-up between the 6-weeks and 6-month time points (68.3% versus 48.2%, respectively; p < 0.0001). Medicaid insurance compared to Medicare (OR 0.27, 95% confidence interval (CI) = [0.09, 0.84], p = 0.02) was a predictor of decreased likelihood of follow-up at 6-months post-operatively.

CONCLUSIONS

Our study demonstrates a statistically significant decrease in follow-up for orthopaedic trauma patients after the post-surgical global period, particularly for patients with Medicaid or Private insurance.

Does prophylactic local tobramycin injection lower open fracture infection rates?

Objective: To determine whether local aqueous tobramycin injection in combination with systemic perioperative IV antibiotic prophylaxis will reduce the rate of fracture-related infection (FRI) after open fracture fixation. Other Outcomes of Interest: (1) To compare fracture nonunion rates and report differences between treatment and control groups and (2) compare bacterial speciation and antibiotic sensitivity among groups that develop FRI. Design: Phase 3 prospective, randomized clinical trial. Setting: Two level 1 trauma centers. Participants: Six hundred subjects (300 in study/tobramycin group and 300 in control/standard practice group) will be enrolled and assigned to the study group or control group using a randomization table. Patients with open extremity fractures that receive definitive internal surgical fixation will be considered. Intervention: Aqueous local tobramycin will be injected into the wound cavity (down to bone) after debridement, irrigation, and fixation, following closure. Main Outcome Measurements: Outcomes will look at the presence or absence of FRI, the rate of fracture nonunion, and determine speciation of gram-negative and Staph bacteria in each group with a FRI. Results: Not applicable. Conclusion: The proposed work will determine whether local tobramycin delivery plus perioperative standard antibiotic synergism will minimize the occurrence of open extremity FRI. Level of Evidence: Level 1.

Incidence and predictors of case cancellation within 24 h in patients scheduled for elective surgical procedures

OBJECTIVE

Avoidable case cancellations within 24 h reduce operating room (OR) efficiency, add unnecessary costs, and may have physical and emotional consequences for patients and their families. We developed and validated a prediction tool that can be used to guide same day case cancellation reduction initiatives.

DESIGN

Retrospective hospital registry study.

SETTING

University-affiliated hospitals network (NY, USA).

PATIENTS

246,612 (1/2016-6/2021) and 58,662 (7/2021-6/2022) scheduled elective procedures were included in the development and validation cohort.

MEASUREMENTS

Case cancellation within 24 h was defined as cancelling a surgical procedure within 24 h of the scheduled date and time. Our candidate predictors were defined a priori and included patient-, procedural-, and appointment-related factors. We created a prediction tool using backward stepwise logistic regression to predict case cancellation within 24 h. The model was subsequently recalibrated and validated in a cohort of patients who were recently scheduled for surgery.

MAIN RESULTS

8.6% and 8.7% scheduled procedures were cancelled within 24 h of the intended procedure in the development and validation cohort, respectively. The final weighted score contains 29 predictors. A cutoff value of 15 score points predicted a 10.3% case cancellation rate with a negative predictive value of 0.96, and a positive predictive value of 0.21. The prediction model showed good discrimination in the development and validation cohort with an area under the receiver operating characteristic curve (AUC) of 0.79 (95% confidence interval 0.79-0. 80) and an AUC of 0.73 (95% confidence interval 0.72-0.73), respectively.

CONCLUSIONS

We present a validated preoperative prediction tool for case cancellation within 24 h of surgery. We utilize the instrument in our institution to identify patients with high risk of case cancellation. We describe a process for recalibration such that other institutions can also use the score to guide same day case cancellation reduction initiatives.

Risk factors for loss to follow up of pelvis and acetabular fractures

INTRODUCTION

Pelvic and acetabular fracture incidence is increasing worldwide for more than four decades. There is currently no evidence examining risk factors for loss to follow up in patients with these injuries.

METHODS

Patients presenting with pelvic and/or acetabular fractures at our institution between 2015 and 2020 were included. Demographic, injury, treatment, and follow up information was included. Excluded patients were those who sustained a pathologic fracture, has a course of treatment prior to transfer to our centre, or expired prior to discharge.

RESULTS

446 patients, 263 with a pelvic ring injury, 172 with an acetabular fracture, and 11 with combined injuries were identified. 271 (61%) of patients in our cohort followed up in Orthopaedic clinic (p = 0.016). With an odds ratio of 2.134, gunshot wound mechanism of injury was the largest risk factor for loss to follow up (p = 0.031) followed by male sex (OR= 1.859) and surgery with general trauma surgery (OR=1.841). The most protective risk factors for follow up with Orthopaedic surgery were operatively treated pelvic and acetabular fractures (OR=0.239) and Orthopaedic Surgery as the discharging service (OR=0.372).

DISCUSSION

Numerous risk factors exist for loss to follow up including male sex, ballistic mechanism, and discharging service. Investigation into interventions to improve follow up in these patients are warranted.

Preoperative Factors Associated with 2-Year Postoperative Survey Completion in Knee Surgery Patients

Patient-reported outcomes, such as the Patient-Reported Outcomes Measurement Information System (PROMIS) measures, have become increasingly valued as measures of treatment. The purpose of the study was to determine preoperative factors associated with survey compliance 2 years after elective knee surgery. Five hundred patients, age 17 years and older, undergoing knee surgery from August 2015 and March 2017 were administered questionnaires preoperatively and 2 years postoperatively. Questionnaires included the International Knee Documentation Committee (IKDC) score, Numeric Pain Scales (NPS), International Physical Activity Questionnaire (IPAQ), and six PROMIS Domains for physical function, pain interference, social satisfaction, fatigue, anxiety, and depression. Three hundred sixty-five patients (73.0%) completed both the preoperative and the 2-year surveys. A decreased likelihood of survey completion was significantly associated with black race, lower income, government-sponsored insurance, smoking, opioid use, fewer previous surgeries, lower expectations, lower PROMIS social satisfaction, higher PROMIS pain interference, and lower IPAQ physical activity. Multivariable logistic regression analysis confirmed that black race and lower IPAQ activity level were independent predictors of lower survey completion at 2-year follow-up with an area under the curve (AUC) of 0.62. A more robust multivariable model that included all variables with p < 0.05 in the bivariate analysis had an AUC of only 0.70. This study identified multiple preoperative factors that were associated with lower survey completion 2 years after elective orthopaedic knee surgery; however, all the factors measured in this study were not strong predictors of survey completion.

Telemedicine and Socioeconomics in Orthopaedic Trauma Patients: A Quasi-Experimental Study During the COVID-19 Pandemic

INTRODUCTION

Socioeconomic factors may introduce barriers to telemedicine care access. This study examines changes in clinic absenteeism for orthopaedic trauma patients after the introduction of a telemedicine postoperative follow-up option during the COVID-19 pandemic with attention to patient socioeconomic status (SES).

METHODS

Patients (n = 1,060) undergoing surgical treatment of pelvic and extremity trauma were retrospectively assigned to preintervention and postintervention cohorts using a quasi-experimental design. The intervention is the April 2020 introduction of a telemedicine follow-up option for postoperative trauma care. The primary outcome was the missed visit rate (MVR) for postoperative appointments. We used Poisson regression models to estimate the relative change in MVR adjusting for patient age and sex. SES-based subgroup analysis was based on the Area Deprivation Index (ADI) according to home address.

RESULTS

The pre-telemedicine group included 635 patients; the post-telemedicine group included 425 patients. The median MVR in the pre-telemedicine group was 28% (95% confidence interval [CI], 10% to 45%) and 24% (95% CI, 6% to 43%) in the post-telemedicine group. Low SES was associated with a 40% relative increase in MVR (95% CI, 17% to 67%, P < 0.001) compared with patients with high SES. Relative MVR changes between pre-telemedicine and post-telemedicine groups did not reach statistical significance in any socioeconomic strata (low ADI, -6%; 95% CI, -25% to 17%; P = 0.56; medium ADI, -18%; 95% CI, -35% to 2%; P = 0.07; high ADI, -12%; 95% CI, -28% to 7%; P = 0.20).

CONCLUSIONS

Low SES was associated with a higher MVR both before and after the introduction of a telemedicine option. However, no evidence in this cohort demonstrated a change in absenteeism based on SES after the introduction of the telemedicine option. Clinicians should be reassured that there is no evidence that telemedicine introduces additional socioeconomic bias in postoperative orthopaedic trauma care.

Scoping review of the literature to ascertain how follow-up care is provided to major trauma patients post discharge from acute care

OBJECTIVES

Survival following traumatic injury has increased, requiring ongoing patient follow-up. While longitudinal outcomes of trauma patients are reported, little is known about optimal delivery of follow-up service for this group. The aim of this scoping review was to identify and describe the structure, process and outcomes of postdischarge follow-up services for patients who sustained major trauma.

EVIDENCE REVIEW

This scoping review was conducted by searching CINAHL, MEDLINE and EMBASE databases. Articles were screened by three independent reviewers. The data of selected articles were organised in the categories of the Donabedian quality framework: structure, processes and outcomes.

RESULTS

Twenty-six articles were included after screening by title/abstract then full text against the inclusion/exclusion criteria; 92% (n=24) were from the USA.Follow-up services were provided by designated trauma centres and delivered by a mixture of health disciplines. Delivery of follow-up was multimodal (in person/telehealth). Protocols and guidelines helped to deliver follow-up care for non-physician led services.Ongoing health issues including missed injuries, pain and infection were identified. No standardised criteria were established to determine recipients, the timing or frequency of follow-up was identified. Patients who engaged with follow-up services were more likely to participate in other health services. Patients reported satisfaction with follow-up care.

CONCLUSION

There are wide variations in how follow-up services for major trauma patients are provided. Further evaluation should focus on patient, family and organisational outcomes. Identifying who is most likely to benefit, when and how follow-up care is delivered are important next steps in improving outcomes.

Patients value their own pain over braking safety when deciding when to return to driving: a discrete choice experiment on lower extremity injuries

Objective

To quantify patient preferences towards time to return to driving relative to compromised reaction time and potential complication risks.

Design

Cross-sectional discrete choice experiment.

Setting

Academic trauma center.

Patients

Ninety-six adult patients with an operative lower extremity fracture from December 2019 through December 2020.

Intervention

None.

Main Outcome Measurement

Patient completed a discrete choice experiment survey consisting of 12 hypothetical return to driving scenarios with varied attributes: time to return to driving (range: 1 to 6 months), risk of implant failure (range: 1% to 12%), pain upon driving return (range: none to severe), and driving safety measured by braking distance (range: 0 to 40 feet at 60 mph). The relative importance of each attribute is reported on a scale of 0% to 100%.

Results

Patients most valued a reduced pain level when resuming driving (62%), followed by the risk of implant failure (17%), time to return to driving (13%), and braking safety (8%). Patients were indifferent to returning to driving at 1 month (median utility: 28, interquartile range [IQR] -31 to 80) or 2 months (median utility: 59, IQR: 41 to 91) postinjury.

Conclusion

Patients with lower extremity injuries demonstrated a willingness to forego earlier return to driving if it might mean a decrease in their pain level. Patients are least concerned about their driving safety, instead placing higher value on their own pain level and chance of implant failure. The findings of this study are the first to rigorously quantify patient preferences toward a return to driving and heterogeneity in patient preferences.

Capturing patient-reported outcomes: paper versus electronic survey administration

Objective: To compare the capture rates and costs of paper patient-reported outcomes (pPRO) administered in-clinic and electronic PROs (ePRO) collected through emails and texts. Design: Retrospective review. Setting: Level 1 trauma center. Patients/Participants: The pPRO program enrolled 2164 patients for postsurgical follow-up in 4 fracture types: ankle, distal radius, proximal humerus, and implant removal from 2012 to 2017. The ePRO program enrolled 3096 patients in 13 fracture types from 2018 to 2020. Among the patients enrolled in the ePRO program, 1296 patients were matched to the 4 original fracture types and time points. Main Outcome Measures: PRO capture rates in 4 fracture types by matched time point and estimated cost of each program per enrolled patient. Results: At first follow-up, pPRO provided a higher capture rate than ePRO for 3 of 4 fracture types except for implant removal (P < 0.05). However, at 6-month and 1-year follow-ups, ePRO demonstrated statistically significant higher capture rates when compared with pPRO for all applicable modules (P < 0.05). The average cost for the pPRO program was $171 per patient versus $56 per patient in the ePRO program. Patients were 1.19 times more likely to complete ePRO compared with pPRO (P = 0.007) after controlling for age, sex, fracture type, and time point. Conclusion: The electronic PRO service has improved long-term capture rates compared with paper PROs, while minimizing cost. A combined program that includes both in-clinic and out of clinic effort may be the ideal model for collection of PROs. Level of Evidence: Level 3.

National Evaluation of Social Determinants of Health in Orthopedic Fracture Care: Decreased Social Determinants of Health Is Associated With Increased Adverse Complications After Surgery

OBJECTIVES

To assess the individual impact of social determinants of health disparities (SDHD) on surgical outcomes following orthopaedic trauma surgery.

DESIGN

Retrospective Cohort Study.

SETTING

Mariner Claims Database.

PATIENTS

Inclusion criteria were patients 18-85 years of age, undergoing surgery for hip fractures or ankle fractures from 2010 to 2018.

INTERVENTION

Patients were divided based on SDHD using International Classification of Diseases 9 and International Classification of Diseases 10 codes. Those with SDHD were propensity-score matched with those who did not have any disparities with respect to age, gender, Charlson comorbidity index, tobacco use, and obesity (body mass index >30 kg/m2).

OUTCOMES

Ninety-day major medical complications, infection, readmission, and revisions within 1 year.

RESULTS

Patients with educational deficiencies had increased rates of readmission and major complications compared with those without disparities following hip and ankle fracture management. Moreover, economic disparities were associated with an increased risk of readmission and revision following hip fracture surgery and infection and readmission following ankle fracture surgery.

DISCUSSION/CONCLUSIONS

This study emphasizes the large impact of SDHD on patients' outcomes following surgery and the importance of proper follow-up interventions to optimize patient care.

The Impact of the Affordable Care Act on Outpatient Spine Trauma Consult Follow-up

STUDY DESIGN

This was a retrospective cohort study.

OBJECTIVE

The objective of this study was to assess the impact of the Affordable Care Act (ACA) on spine trauma patient follow-up.

SUMMARY OF BACKGROUND DATA

Although damage to the spinal column accounts for a small proportion of all traumatic injuries, it results in a significant burden on the patient, provider, and health care system. Postoperative follow-up is essential to direct rehabilitation, prevent early deterioration, and manage complications early in the postoperative period. Previous studies have established the role of insurance coverage on follow-up compliance, however, the impact of the ACA on follow-up has been scant.

MATERIALS AND METHODS

A retrospective cohort study was performed upon institutional review board approval of spine trauma patients consulted by orthopedic spine or neurosurgery from January 2013 to December 2013 (pre-ACA) and January 2015 to December 2015 (post-ACA). Patient demographics, surgical case characteristics, and follow-up compliance were assessed via manual chart review. Multivariate regression analysis was used to identify predictors of follow-up in the overall cohort, as well as within nonoperative and operative patients.

RESULTS

A total of 827 patients were included in the final analysis after inclusion and exclusion criteria. Overall, patient follow-up significantly increased after implementation of the ACA (P<0.001), with pre-ACA follow-up at 35.0% (144/411) and post-ACA follow-up at 50.0% (208/516). Multivariate regression analysis further corroborated these findings, showing post-ACA status associated with a 1.66-fold higher likelihood of follow-up. Among nonoperative patients, the ACA failed to make a significant difference in follow-up (P=0.56), however, patients treated operatively showed a significantly higher likelihood of follow-up (odds ratio=2.92, P<0.001).

CONCLUSIONS

Postoperative follow-up is an essential part of patient care, aiding in improving clinical outcomes and limiting the economic burden on the health care system. This study suggests that passage of the ACA significantly improved patient follow-up for operatively managed patients but not for nonoperatively managed patients.

Early hip survival after open reduction internal fixation of acetabular fracture

PURPOSE

To estimate survival of acetabular fracture repair by tracking patients across healthcare encounters. We hypothesized that hip survival estimated this way would be lower than reported by single-surgeon or single-center series not capturing censored reoperations.

METHODS

Retrospective health insurance administrative database cohort study. All claimed healthcare encounters for employer-sponsored health insurance beneficiaries aged 18-65 years without pre-existing hip pathology with a newly diagnosed acetabular fracture were identified between October 1, 2015, through December 31, 2018. The intervention was open reduction internal fixation of acetabular fracture during index admission. The primary outcome was survival of the acetabular fracture repair to subsequent reoperation by arthroscopy, arthrotomy for drainage of infection, implant removal, revision acetabular fixation, hip arthroplasty, hip resection, or arthrodesis.

RESULTS

38 reoperation procedures on the fractured acetabulum in 852 patients occurred within 2 years (incidence 4.5%). Total hip arthroplasty (2.5%) and revision internal fixation (1.5%) accounted for most early reoperations. Multivariable Cox regression identified an association between reoperation and increasing patient age (hazard ratio = 1.4 per decade, p < 0.01). The prevalence of any mental health condition was 29%.

CONCLUSIONS

Non-elderly adults with employer-sponsored insurance who sustain acetabular fractures have a greater burden of mental health disease than similarly insured patients without these injuries. Survival of the native acetabulum after fracture fixation exceeded 95% at 2 years and decreased with increasing patient age.

Lost in Follow-Up: Predictors of Patient No-Shows to Clinic Follow-Up After Abdominal Injury

BACKGROUND

The aim of this study is to evaluate risk factors for non-attendance to post-discharge, hospital follow-up appointments for traumatically injured patients who underwent exploratory laparotomy.

METHODS

This is a retrospective chart review of patients who underwent exploratory laparotomy for traumatic abdominal injury at an urban, Midwestern, level I trauma center with clinic follow-up scheduled after discharge. Clinically, relevant demographic characteristics, patients' distance from hospital, and the presence of staples, sutures, and drains requiring removal were collected. Descriptive statistics of categorical variables were calculated as totals and percentages and compared with a chi-squared test or Fisher's exact when appropriate.

RESULTS

The sample included 183 patients who were largely assaultive trauma survivors (68%), male (80%), and black (53%) with a mean age of 35.4 ± 14.9 years. Overall, 18.5% no-showed for their follow-up appointment. On multivariate analysis for clinic no-show; length of stay (odds ratio = 0.92 [0.84-0.99], P = 0.04) and the need for suture, staple, or drain removal were protective for clinic attendance (odds ratio = 5.59 [1.07-7.01], P = 0.04). Overall, 12 patients (6.4%) were readmitted. Forty patients (18.3%) had their follow-up in the emergency department (ED). On multivariate regression of risk factors for ED visits, the only statistically significant factors (P < 0.05) were clinic appointment no-show (OR = 2.81) and self-pay insurance (OR = 4.78).

CONCLUSIONS

Abdominal trauma patients are at high risk of no-show for follow-up appointments and no-show visits are associated with ED visits. Future work is needed evaluating interventions to improve follow-up.

Trauma clinic follow-up: Predictors of nonattendance and patient-reported reasons for no show

Introduction

The objectives of this study were to identify factors associated with nonattendance to follow-up in patients seen for traumatic hand and facial injuries at an urban Level 1 trauma center and to elucidate patient-reported reasons for nonattendance.

Methods

A retrospective chart review was performed for all patients seen for hand and facial trauma at our institution over a 2-year period. Demographic data, including race, insurance status, and incomes based on zip code data, were collected for all patients. Injury patterns, interventions, and patient disposition were analyzed. A binomial multivariate logistic regression was conducted to identify predictors of nonattendance to follow-up. All patients who were lost to follow-up over the last 12-month period were contacted via phone to identify reasons for nonattendance to determine whether they had followed up with another provider and to analyze long-term injury sequelae.

Results

After exclusion criteria were applied, there were 889 patients included in the analysis, with 31% of patients lost to follow-up. Factors significantly associated with follow-up nonattendance included patients who sustained injuries from gunshot wounds or assault, had no insurance or were out of network, and who received no acute intervention for their injuries. Forearm, wrist, and fingers fractures; facial fractures and lacerations; performing a procedure in the ED or operating room; and commercial insurance were all independent predictors of clinic attendance. The most common reasons for nonattendance cited by patients were “did not feel the need” (28%), lack of transportation (20%), and scheduling conflicts (19%).

Conclusions

Clinic follow-up for patients sustaining hand and facial trauma at a Level 1 trauma center is impacted by the socioeconomic factors that make this patient population particularly vulnerable to injury.

Intentional Fallers with Complex Pelvic and Acetabular Fractures Do Not Have worse Radiological and Functional Outcomes than Accidental Fallers

Individuals who fall from heights of ≥6 m can suffer from complex pelvic and acetabular fractures. The extent to which an intentional fall correlates with prognosis and outcome after osteosynthesis is unclear. Therefore, we aimed to investigate the clinical outcomes of fallers with pelvic and acetabular fractures after osteosynthesis and compare the radiological and functional outcomes between intentional and accidental fallers. We retrospectively reviewed 49 fallers who fell from heights of ≥6 m, developed pelvic and acetabular fractures, survived after resuscitation, and completed surgical treatment between 2014 and 2017. Fallers were divided into intentional and accidental fallers. Sixteen patients were intentional fallers, whereas the rest of the patients were accidental fallers. Psychiatric counseling was provided to each of the intentional fallers during follow-up. All intentional fallers had preexisting mental disorders, and the most common diagnosis was adjustment disorder. The group of intentional fallers predominantly comprised females that had a higher injury and new injury severity scores and longer hospital stays. However, early loss of fixation (<3 months) and functional outcomes (Merle d'Aubigné and Majeed hip scores at 6- and 12-month follow-ups) did not significantly differ between intentional and accidental fallers. We found that intentional fallers with pelvic and acetabular fractures may have more severe combined injuries compared to accidental fallers. However, the radiological and functional outcomes of the intentional fallers after osteosynthesis were not inferior to those of the accidental fallers with the implementation of well-designed surgical protocols and individualized physical and mental rehabilitation programs.

Predictors of appointment adherence following operative treatment of pediatric supracondylar humerus fractures: which patients are not following up?

This study aims to identify characteristics associated with poor appointment adherence after surgical stabilization of supracondylar humerus fractures (SCHFX) in children. A retrospective review of 560 consecutive, surgically managed patients with SCHFX from 2010 to 2015 was performed. One missed follow-up appointment was classified as 'low adherence', whereas missing two or more appointments was classified as 'very low adherence'. Demographics, insurance status, estimated family income and distance from clinic were analyzed to identify differences in variables between adherent and low-adherent groups. Of 560, 121 (21.8%) missed one follow-up visit and 39/560 (7.1%) missed more than two visits. Age, gender, distance traveled, insurance status and primary language were nonpredictive. Estimated income <$50 000 was associated with a >200% increase in low adherence vs patients with estimated income >$50 000 (9.3 vs 3.8%; P = 0.012). African American patients had significantly lower adherence vs patients of other races (47.5 vs 19.6%; P < 0.0001). Ethnicity remained the only significant factor correlated to adherence after multivariate analysis. African Americans were three times more likely demonstrate low adherence (P = 0.0014). Ethnicity and estimated income <$50 000 were predictors of missing two or more visits. African American patients were four times more likely to miss two or more visits [odds ratio (OR), 4.17; P = 0.0026] than others; estimated income <$50 000 was associated with a two-fold increase in missing two or more visits (OR, 2.33; P = 0.035). By identifying at-risk patient populations, healthcare systems can adopt strategies to remove barriers of accessing follow-up care.

Understanding factors in burn patient follow-up

Follow-up rates (FUR) are concerningly low among burn-injured patients. This study investigates the factors associated with low FUR and missed appointments (MA). We hypothesize that patients who are homeless, use illicit substances, and have psychiatric comorbidities will have lower rates of follow-up (FU) and more MAs. Data from a discharge-planning survey of 281 burn-injured patients discharged from September 2019 - July 2020 was analyzed and matched with patients' EMR records for a retrospective chart review. Data collected included general demographics, burn characteristics, hospitalization details, FU visits, MAs, homeless status, substance use, major psychiatric illness (MPI), and survey responses. Data analysis used Chi-square, Fisher's exact test, Student t-test, Wilcox Rank Sum test, and Multivariate Regression Analysis (MVR). Overall, 37% of patients had no FU in clinic and 46% had one or more MA. On MVR, homeless patients were more likely to never follow up, OR = 0.227 (95% CI = 0.106-0.489), as were patients who anticipated transportation difficulties, OR = 0.275 (95% CI = 0.151-0.501). Homeless patients were more likely to have MA, OR= 0.231 (95% CI = 0.099-0.539). On univariate analysis, patients with one or more documented MPI had lower FUR, with 50.62% having no FU (p = 0.0020). Among patients who responded to the survey that they were current drug users, 52% had no FU as compared to 28% of patients who responded that they did not use drugs (p = 0.0007). Factors associated with lower FUR and more MAs include homeless status, substance use, MPI, and transportation difficulties.

Epidemiology and risk factors for loss to follow-up following operatively treated femur ballistic fractures

INTRODUCTION

Evidence regarding recommendations for treatment of ballistic fractures remains limited. This paucity of literature has largely been attributed to gunshot wound victims being a difficult population to study secondary to loss to follow-up. The purpose of this study was to examine the epidemiology of operatively treated ballistic femur fractures at our institution, the frequency of outpatient follow-up and risk factors for loss to follow-up.

METHODS

Inpatient consults from 2013-2018 were queried for femoral gunshot wounds treated operatively. Cases without internal or external fixation were excluded from the study. Postoperative visits where a patient was hospitalized or had expired were excluded from the analysis. Demographic information, length of hospital stay, and operative characteristics were compared for different fixation methods and examined as risk factors for loss to follow-up.

RESULTS

A total of 194 patients met inclusion criteria. The average age was 27 years old and 94% of the patients were male. Patient's stayed a median of 5 days post-operatively with patients treated with external fixation staying longer than internal fixation (14 days vs 5 days p=0.01). 9.3% of ballistic fractures had a concomitant vascular injury necessitating repair. 70.4% of patients attended their 2-week postoperative visit, 55.7% of patients attended their 6 week follow-up visit and 31.3% attended their 3 month follow-up visit. Risk factors for loss to follow-up at 3 month visit included younger age (p=0.028), decreased hospital length of stay (p=0.025) and intramedullary fixation (p=0.00015).

DISCUSSION AND CONCLUSION

This study reinforces the difficulty of studying ballistic fractures secondary to loss to follow-up. Younger age, shorter hospital stays and intramedullary fixation increased the risk for loss to follow-up at 3 months.

Evaluation of postoperative outcomes in patients following multi-level surgical reconstructions with the use Avive™ soft tissue membrane on nerve after traumatic injury of the upper extremity and lower extremity

Background

Treatment of patients with traumatic axonotmesis presents challenges. Processed human umbilical cord membrane has been recently developed with improved handling and resorption time compared to other amniotic membrane wraps, and may be beneficial in nerve reconstruction. This study evaluates postoperative outcomes after traumatic peripheral nerve injury after placement of commercially available processed human umbilical cord membrane.

Methods

We performed a prospective, single-center pilot study of patients undergoing multi-level surgical reconstruction for exposed, non-transected peripheral nerve. Functional outcomes including pain, range of motion, pinch and grip strength, and the QuickDASH and SF-36 patient-reported outcome measures were recorded, when possible, at the 1-week and 3, 6, and 9 months postop visit. One-tailed paired t-tests were performed to evaluate outcome improvement at final follow-up.

Results

Twenty patients had processed human umbilical cord membrane placement without surgical complications. Mean follow-up was 7.5 months (range: 3-10 months) and mean age was 39 years (range: 15-65). Twelve (67%) patients were male, and the majority of placement sites were in the upper extremity (85%). Mean preoperative visual analog scale pain score was significantly reduced at most recent follow-up, as were QuickDASH scores. All patients had improved functional outcomes at the 9-month follow-up, and SF-36 outcomes at 9 months showed improvement across all dimensions.

Conclusion

This study indicates that processed human umbilical cord membrane may be a useful adjunct in nerve surgery with noted improvements in postoperative function, pain, and patient-reported outcome measures. Future studies are needed to assess long-term outcomes after traumatic nerve injury treated with processed human umbilical cord membrane.

The Canadian Orthopaedic Trauma Society

AIMS

This study reviews the past 30 years of research from the Canadian Orthopedic Trauma Society (COTS), to identify predictive factors that delay or accelerate the course of randomized controlled trials in orthopaedic trauma.

METHODS

We conducted a methodological review of all papers published through the Canadian Orthopaedic Trauma Society or its affiliates. Data abstracted included: year of publication; journal of publication; study type; number of study sites; sample size; and achievement of sample size goals. Information about the study timelines was also collected, including: the date of study proposal to COTS; date recruitment began; date recruitment ended; and date of publication.

RESULTS

In total, 22 studies have been published through the COTS working group, 13 of which are randomized controlled trials (RCTs). In total, 1,423 individual patients have been involved in COTS studies, a mean of 110 patients per trial (22 to 424). Each study was conducted across a mean of approximately six centres (1 to 11) and took nearly ten years (mean 119.9 months (59 to 188)) from presentation of concept to publication. The mean length of enrolment was 63 months (26 to 113) and the mean time from cessation of enrolment to publication 51 months (19 to 78). Regardless of sample size, the only factor associated with a decreased length of enrolment was a higher number of clinical sites (p = 0.041). Neither study sample size nor length of enrolment were associated with total time to publication.

CONCLUSION

Over the last three decades, COTS has developed a multinational strategy to produce high-quality evidence in the field of orthopaedic trauma through 13 multicentre RCTs. Future efficiencies can be realized by recruitment of more clinical sites, improving connectivity between the sites, and the promotion of national streamlined ethics processes.

Follow-up After Burn Injury Is Disturbingly Low and Linked With Social Factors

For medical and social reasons, it is important that burn patients attend follow-up appointments (FUAs). Our goal was to examine the factors leading to missed FUAs in burn patients. A retrospective chart review was conducted of adult patients admitted to the burn center from 2016 to 2018. Data collected included burn characteristics, social history, and zip code. Data analysis was conducted using chi-square, Wilcoxon Rank-Sum tests, and multivariate regression models. A total of 878 patients were analyzed, with 224 (25.5%) failing to attend any FUAs and 492 (56.0%) missing at least one appointment (MA). Patients who did not attend any FUAs had smaller burns (4.5 [8]% vs 6.5 [11]% median [inter quartile range]), traveled farther (70.2 [111.8] vs 52.5 [76.7] miles), and were more likely to be homeless (22.8% vs 6.9%) and have drug dependence (47.3% vs 27.2%). Patients who had at least one MA were younger (42 [26] vs 46 [28] years) and more likely to be homeless (17.5% vs 2.6%) and have drug dependence (42.5% vs 19.4%). On multivariate analysis, factors associated with never attending an FUA were distance from hospital (odds ratio [OR] 1.004), burn size (OR 0.96), and homelessness (OR 0.33). Factors associated with missing at least one FUA: age (OR 0.99), drug dependence (OR 0.46), homelessness (OR 0.22), and Emergency Department visits (OR 0.56). A high percentage of patients fail to make any appointment following their injury and/or have at least one MA. Both FUAs and MAs are influenced by social determinants of health.

The Fallacy of Follow-up: When Orthopaedic Trauma Patients Actually Return to Clinic

BACKGROUND

Clinical follow-up in orthopaedic trauma is challenging, yet expectations exist that a 1-year follow-up is the minimum requirement for clinical trials and research publications. The primary purpose of our study was to evaluate the rate of follow-up after operative orthopaedic trauma care and the relationship to clinical care. Our secondary aim was to identify any independent risk factors regarding follow-up completion.

METHODS

A chart review of patients operatively treated for a traumatic injury during the months of January and July 2016 was conducted. Patient demographic characteristics, injury type, severity, and patient distance from the hospital were collected. The final clinical instructions and whether a return visit was requested or as needed were recorded.

RESULTS

There were 293 patients in this study, of whom 84 (29%) had follow-up of at least 1 year and 52 (18%) were instructed to follow up only as needed at their last visit prior to the 1-year mark. When removing the latter 52 patients, the 1-year follow-up rate was 35% (84 of 241 patients). Of these 241 patients, 157 (65%) were requested to return for additional clinical care but failed to return prior to 1 year. Logistic regression identified tobacco use (odds ratio [OR], 0.34 [95% confidence interval (CI), 0.15 to 0.77]; p = 0.010), final appointment status (OR, 6.3 [95% CI, 3.4 to 11.6]; p < 0.001), isolated compared with multiple fractures (OR, 2.2 [95% CI, 1.2 to 4.1]; p = 0.013), and distance from the trauma center per mile as a continuous variable (OR, 0.999 [95% CI, 0.998 to 1.0]; p = 0.03) as significant predictors.

CONCLUSIONS

Our data suggest that a 1-year clinic follow-up requirement may not be feasible. We observed a low rate of patients with a minimum 1-year clinical follow-up. Clinical care had been completed in 18% of patients prior to 1 year. Journal and grant reviewers may need to consider the feasibility and clinical relevance of these follow-up expectations.

Feasibility of Rapid Development and Deployment of a Telemedicine Program in a Foot and Ankle Orthopedic Practice

BACKGROUND

A lack of access to care is predictably associated with negative outcomes in foot and ankle surgery. Despite recent advances in telecommunication technologies, the field of orthopedics has been slow to adopt these resources in offsetting barriers to care. The COVID-19 pandemic has forced departments to change their clinical approach, lending unprecedented opportunity to better understand how telehealth may bridge this care gap in foot and ankle practices. The purpose of this study was to assess patient-reported outcomes of telemedicine encounters, including comfort and patient satisfaction. Our hypothesis was that patients would be significantly less satisfied with telemedicine when compared with in-office appointments for all nonemergency visit types.

METHODS

Telemedicine satisfaction was assessed via phone survey with a modified 1 to 5 Likert scale. Patients who had completed a telemedicine visit between April 13, 2020, and June 19, 2020, were eligible to participate. Patient demographics were recorded, and data were analyzed using paired and independent t tests for parametric continuous data and Fisher's exact and chi-square tests for noncontinuous data. A total of 216 patients completed the telemedicine questionnaire.

RESULTS

The overall mean satisfaction for telemedicine visits (4.7) was significantly lower than that for in-office visits (4.9) (P < .001). However, the majority (90.3%) of patients reported they would use telemedicine again in the future. When compared, patients seeking fracture care had significantly higher telemedicine satisfaction (4.9, n = 38) than those receiving nonfracture care (4.6, n = 178) (P = .001), and those greater than 50 miles from the clinic had higher satisfaction (5.0, n = 14) than patients living within 50 miles of the clinic (4.7, n = 202) (P < .001).

CONCLUSION

Patients were more satisfied with their in-office clinic visit than telemedicine, although the vast majority of patients endorsed a willingness to utilize telemedicine in the future. Patients with trauma and greater barriers to foot and ankle care were more satisfied with their telemedicine visits.

The Reliability of Remote Patient-Reported Outcome Measures via Mobile Apps to Replace Outpatient Visits After Rotator Cuff Repair Surgery: Repetitive Test-Retest Comparison Study for 1-Year Follow-up

BACKGROUND

With the development of health care-related mobile apps, attempts have been made to implement remote patient-reported outcome measures (PROMs). In order for remote PROMs to be widely used by mobile apps, the results should not be different depending on the location; that is, remote PROM results performed in locations other than hospitals should be able to obtain reliable results equivalent to those performed in hospitals, and this is very important. However, to our knowledge, there are no studies that have assessed the reliability of PROMs using mobile apps according to the location by comparing the results performed remotely from the hospital and performed at the outpatient visits.

OBJECTIVE

The purpose of this study was to evaluate the reliability of remote PROMs using mobile apps compared to PROMs performed during outpatient follow-up visits after arthroscopic shoulder surgery.

METHODS

A total of 174 patients who underwent arthroscopic rotator cuff repair completed questionnaires 2 days before visiting the clinic for the 1-, 2-, 3-, 6-, and 12-month follow-ups (test A). The patients completed the questionnaires at the clinic (test B) using the same mobile app and device for the 1-, 2-, 3-, 6-, and 12-month follow-ups. Test-retest comparisons were performed to analyze the differences and reliability of the PROMs according to the period.

RESULTS

Comparisons of tests A and B showed statistically significant differences at 1, 2, and 3 months (all Ps<.05 except for the ASES function scale at 3-months) but not 6 or 12 months after surgery (all Ps>.05). The intraclass correlation values between the two groups were relatively low at the 1-, 2-, and 3-month follow-ups but were within the reliable range at 6 and 12 months after surgery. The rate of completion of tests A and B using the mobile app was significantly lower in the group older than 70 years than in the other groups for all postoperative periods (P<.001).

CONCLUSIONS

PROMs using mobile apps with different locations differed soon after surgery but were reliably similar after 6 months. The remote PROMs using mobile apps could be used reliably for the patient more than 6 months after surgery. However, it is to be expected that the use of mobile app-based questionnaires is not as useful in the group older than 70 years as in other age groups.

Do patient outcomes and follow-up completion rates after shoulder arthroplasty differ based on insurance payor?

BACKGROUND

Disparities associated with socioeconomic status (SES) and insurance coverage have been shown to affect outcomes in different medical conditions and surgical procedures. We hypothesized that patients insured by Medicaid will be associated with lower follow-up rates and inferior outcomes relative to those with Medicare or private insurance.

METHODS

Patients undergoing shoulder arthroplasty, including anatomic total shoulder arthroplasty, reverse arthroplasty, and hemiarthroplasty, were enrolled preoperatively in an institutional database. Preoperative demographics, payor (Medicaid, Medicare, or private insurance), and baseline American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores were recorded. Postoperatively, patients completed ASES scores at multiple time points. Follow-up completion rate was calculated as the number of follow-up visits completed relative to possible visits. Continuous variables were compared between groups with 1-way analyses of variance, and chi-squared tests were used for categorical variables. Significance was defined as P < .05.

RESULTS

There were 491 shoulder replacements performed for 438 patients from 2012-2017. The mean follow-up completed percentage was significantly lower (P < .001) for Medicaid patients (62.6% ± 33.7%) relative to Medicare patients (80.2% ± 26.7%; P < .001) and private insurance patients (77.8% ± 22.1%; P = .001). The ASES Composite score increased significantly for all patients from baseline to final follow-up. At each time point, including before surgery and each postoperative time point, patients with Medicaid insurance had significantly lower ASES Composite scores. The final ASES Composite score was significantly lower in the Medicaid patients (66.1 ± 28.7) relative to private insurance patients (78.3 ± 20.8; P = .023). Medicaid patients had significantly lower preoperative (P < .001) and postoperative (P = .018) ASES Pain subscores. In multivariate regression analysis, Medicaid insurance was associated with both inferior preoperative and postoperative ASES scores relative to patients with Medicare or private insurance.

CONCLUSIONS

We observed that all patients, regardless of insurance payor, improved by similar magnitudes after shoulder arthroplasty, though patients with Medicaid insurance had significantly lower preoperative and postoperative ASES scores, primarily because of the ASES Pain subscore. Patients with Medicaid insurance also have lower follow-up rates than other payors.

Predicting no-shows in paediatric orthopaedic clinics

Background

Clinic ‘no shows’ (NS) can be a burden on the healthcare system, and efforts to minimise them can reduce lost revenue and improve patient care. Leveraging a large data set via the electronic health record (EHR) has not been previously attempted to identify ‘high risk’ groups in paediatric orthopaedics.

Objective

To use discrete data captured by the EHR system to identify predictors of non-attendance at paediatric orthopaedic outpatient appointments.

Methods

Appointments from January 2014 to March 2016 were included. Variables included appointment status, age, gender, type of visit, payor type (government vs private insurance), distance of residence to clinic, region of residence, clinic location, clinic type, and appointment day of the week, hour and month. Classification and regression trees (CART) were constructed to identify predictors of NS.

Results

131 512 encounters were included, 15 543 of which were in the NS group (11.8%). CART identified three predictive covariates for NS: days in between scheduling and appointment, insurance type, and specific orthopaedic clinic type. The combination of covariates provided predictability of NS: if they had ≤38.5 days of waiting for appointment and had private insurance, the NS rate was 7.8% (the best result), compared with waiting >38.5 days for either a fracture or sports clinic, which had an NS rate of 29.3% (OR=4.9).

Conclusion

Payor type and duration between scheduling and appointment may predict non-attendance at outpatient paediatric orthopaedic appointments. Although these findings allow for predicting and interventions for at-risk groups, even the best performing NS group occurred 7.8% of the time, highlighting the complexity of the NS phenomenon.

Improvement in Outpatient Follow-up With a Postdischarge Phone Call Intervention

INTRODUCTION

Attending clinic appointments after injury is crucial for orthopaedic trauma patients to evaluate healing and to update recommendations. However, attendance at these appointments is inconsistent. The purpose of this study was to assess the effect of a personalized phone call placed 3 to 5 days after hospital discharge on attendance at the first postdischarge outpatient clinic visit.

METHODS

This prospective study was done at an urban level 1 trauma center. One hundred fifty-nine patients were exposed to a reminder phone call, with 33% of patients being reached for a conversation and 28% receiving a voicemail reminder. Phone calls were made by a trained trauma recovery coach, and the main outcome measure was attendance at the first postdischarge clinic visit.

RESULTS

Eighty-six patients (54%) attended their scheduled appointments. Appointment adherence was more common among the group reached for a conversation (70% versus 51% for voicemail cohort and 34% for no contact group). Patients exposed to the Trauma Recovery Services (TRS) during their hospital stay attended appointments more often (91% versus 61%, P = 0.026). Age, sex, mechanism of injury, and distance from the hospital were not associated with specific follow-up appointment adherence. Insured status was associated with higher attendance rates (71% versus 46%, P = 0.0036). Other economic factors such as employment were also indicative of attendance (64% versus 48%, P = 0.05). Current tobacco use was associated with poor appointment attendance (30%) versus 56% for nonsmokers (P = 0.001).

DISCUSSION

Patients reached by telephone after discharge had better rates of subsequent clinic attendance. Economic factors and substance use appear vital to postoperative clinic visit compliance. Patients with met psychosocial needs, as identified by individuals with satisfactory emotional support, and exposure to TRS had the highest rates of postdischarge appointment attendance.

Delay of Antibiotic Administration Greater than 2 Hours Predicts Surgical Site Infection in Open Fractures

AIMS

Antibiotic administration, severity of injury, and debridement are associated with surgical site infection (SSI) after internal fixation of open fractures. We sought to validate a time-dependent treatment effect of antibiotic administration.

PATIENTS

Consecutive open fracture patients at a level 1 trauma center with minimum 30-day follow-up were identified from an orthopaedic registry from 2013-2017.

METHODS

The primary endpoint was SSI within 90 days. A threshold time to antibiotic administration associated with SSI was ascertained by receiver-operator analysis. A Cox proportional hazards model adjusted for age, smoking, and drug use determined the treatment effect of antibiotic administration within the threshold period.

RESULTS

Ten percent of 230 patients developed a SSI. There was a trend for patients who did not develop an SSI to receive antibiotics earlier than those who did develop an SSI (61 minutes, IQR 33-107 vs 83 minutes, IQR 40-186), p=0.053). Intravenous antibiotic administration after 120 minutes of presentation of an open fracture to emergency department was significantly associated with a 2.4 increased hazard of surgical site infection (p=0.036) within 90 days.

CONCLUSION

Antibiotic administration greater than 120 minutes after ED presentation of an open fracture was associated with an increased risk of SSI.

Assessing the Role of Patient Race in Disparity of 90-Day Brain Tumor Resection Outcomes

BACKGROUND

This study assesses the influence of race on patient outcomes in a brain tumor surgery population.

METHODS

Coarsened exact matching was used to retrospectively analyze 1700 supratentorial brain tumor procedures over a 6-year period (June 7, 2013 to April 29, 2019) at a single, multihospital academic medical center. Outcome measures included readmission, mortality, emergency room visits, and reoperation.

RESULTS

McNemar test (mid-P) showed no significant difference in 90-day mortality between the 2 races (P = 0.3018). However, there was a significant difference in 90-day readmissions between the 2 races (P = 0.0237). There was no significant difference in 90-day emergency room visits (P = 0.0579), 90-day return to surgery after index admission (P = 0.6015), or return to surgery within 90 days (P = 0.6776) between the 2 races. There was also no significant difference in return to surgery for the duration of the follow-up period (P = 0.8728).

CONCLUSIONS

This study suggests that race alone does not result in disparate outcomes; however, there was an associated difference in 90-day postsurgical readmissions. Despite coarsened exact matching, persistent differences in median household income may play a role in the disparate outcome noted.

Factors associating with surgical site infection following operative management of malleolar fractures at an urban level 1 trauma center

OBJECTIVES

To identify comorbidities and injury characteristics associated with surgical site infection (SSI) following internal fixation of malleolar fractures in an urban level 1 trauma setting.

DESIGN

Retrospective.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

Seven-hundred seventy-six consecutive patients with operatively managed malleolar fractures from 2006 to 2016.

INTERVENTION

Open reduction internal fixation.

MAIN OUTCOME MEASUREMENTS

Superficial SSI (erythema and drainage treated with oral antibiotics and wound care) or deep SSI (treated with surgical debridement and antibiotics).

RESULTS

Fifty-six (7.2%) patients developed SSI, with 17 (30%) of these being deep infections. An a-priori power analysis of n = 325 (α=0.05, β=0.2) was tabulated for differences in univariate analysis. Univariate analysis identified categorical associations (P < .05) between SSI and diabetes mellitus, drug abuse, open fracture, and renal disease but not tobacco abuse, body mass index, or neuropathy. Multivariate logistic regression identified categorical associations between diabetes (OR = 2.2, 95% CI: 1.1-4.3), drug abuse (OR = 3.9, 95% CI: 1.2-12.7), open fracture (OR = 4.1, 95% CI: 1.3-12.8), and renal disease (OR = 2.7, 95% CI: 1.4-5.0) and any (superficial or deep) SSI. A separate multivariate logistic regression analysis found categorical associations between deep SSI requiring reoperation and diabetes (OR = 4.4, 95% CI: 1.6-12.2) and open fracture (OR = 4.1, 95% CI: 1.3-12.8). Furthermore, American society of anesthesiologists classification (ASA) Class 4 patients were (OR = 9.2, 95% CI: 2.0-41.79) more likely to experience an SSI than ASA Class 1 patients.

CONCLUSIONS

Factors associated with SSI following malleolar fracture surgery in a single urban level 1 trauma center included diabetes, drug abuse, renal disease, and open fracture. The presence of diabetes or open type fractures were associated with deep SSI requiring reoperation.

Open Reduction Is Associated With Greater Hazard of Early Reoperation After Internal Fixation of Displaced Femoral Neck Fractures in Adults 18-65 Years

OBJECTIVES

To determine (1) which factors are associated with the choice to perform an open reduction and (2) by adjusting for these factors, if the choice of reduction method is associated with reoperation.

DESIGN

Retrospective cohort study with radiograph and chart review.

SETTING

Twelve Level 1 North American trauma centers.

PATIENTS

Two hundred thirty-four adults 18-65 years of age with an isolated, displaced, OTA/AO type 31-B2 or type 31-B3 femoral neck fracture treated with internal fixation with minimum of 6-month follow-up or reoperation. Exclusion criteria were pathologic fractures, associated femoral head or shaft fractures, and primary arthroplasty.

INTERVENTION

Open or closed reduction technique during internal fixation.

MAIN OUTCOME

Cox proportional hazard of reoperation adjusting for propensity score for open reduction based on injury, demographic, and medical factors. Reduction quality was assessed by 3 senior orthopaedic traumatologists as "acceptable" or "unacceptable" on AP and lateral postoperative radiographs.

RESULTS

Median follow-up was 1.5 years. One hundred six (45%) patients underwent open reduction. Reduction quality was not significantly affected by open versus closed approach (71% vs. 69% acceptable, P = 0.378). The propensity to receive an open reduction was associated with study center; younger age; male sex; no history of injection drug use, osteoporosis, or cerebrovascular disease; transcervical fracture location; posterior fracture comminution; and surgery within 12 hours. A total of 35 (33%) versus 28 (22%) reoperations occurred after open versus closed reduction (P = 0.056). Open reduction was associated with a 2.4-fold greater propensity-adjusted hazard of reoperation (95% confidence interval 1.3-4.4, P = 0.004). A total of 35 (15%) patients underwent subsequent total hip arthroplasty or hemiarthroplasty.

CONCLUSIONS

Open reduction of displaced femoral neck fractures in nonelderly adults is associated with a greater hazard of reoperation without significantly improving reduction. Prospective randomized trials are indicated to confirm a causative effect of open versus closed reduction on outcomes after femoral neck fracture.
