Utilizing the arts to improve health, resilience, and well-being (HeRe We Arts®): a randomized controlled trial in community-dwelling individuals with chronic medical conditions

Background

Healthcare workers are concerned with promoting behavior changes that enhance patients' health, wellness, coping skills, and well-being and lead to improved public health. The purpose of this randomized controlled trial was to determine if participation in an 8-week arts-based program leads to improved mood, health, resilience, and well-being in individuals with chronic health conditions as compared to a wait list control group.

Methods

Self-report questionnaires for well-being, mental health, physical health, overall health, social health, mood, coping, and resilience were administered at baseline, Week 8 (end of program), and Week 16 (8-week follow-up).

Results

Statistically significant improvements were noted in all outcome measures for the treatment group, as well as in most areas compared to the control group. Many of the positive results at Week 8 were either maintained or further improved at Week 16.

Discussion

These results suggest that arts-based programming can have a positive effect on the mood, health, resilience, and well-being of individuals with chronic health conditions. Therefore, arts-based programming should be utilized more frequently in the management of chronic conditions in community-dwelling individuals. These benefits should be further assessed in larger clinical trials.

Impact of Geriatric Consult Evaluations on Hospital Admission Rates for Older Adults

Introduction

We examined the impact of a geriatric consult program in the emergency department (ED) and an ED observation geriatric care unit (GCU) setting on hospital admission rates for older ED patients.

Methods

We performed a retrospective case control study from June 1-August 31, 2019 (pre-program) to September 24, 2019-January 31, 2020 (post-program). Post-program geriatric consults were readily available in the ED and required in the GCU setting. Hospital admission rates (outcome) are reported for patients who received a geriatric consult evaluation (intervention). We analyzed probability of admission using a mixed-effects logistic regression model that included age, gender, recent ED visit, Charlson Comorbidity Index, referral to ED observation, and geriatric consult evaluation as predictor variables.

Results

A total of 9,663 geriatric ED encounters occurred, 4,042 pre-program and 5,621 post-program. Overall, ED admission rates for geriatric patients were similar pre- and post-program (44.8% vs 43.9%, P = 0.39). Of 243 geriatric consults, 149 (61.3%) occurred in the GCU. Overall admission rates post-program for patients receiving geriatric intervention were significantly lower compared to pre-program (23.4% vs 44.9%, P < 0.001). Post-program GCU hospital admission rates were significantly lower than pre-program ED observation unit admission rates (14/149, 9.4%, vs 111/477, 23.3%, P < 0.001). In the logistic regression model, admissions post-program were lower when a geriatric consult evaluation occurred (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.41-0.83). Hospital admissions for older ED observation patients were also significantly decreased when a geriatric consult was obtained (GCU vs pre-program ED observation unit; OR 0.27, 95% CI 0.14-0.50).

Conclusion

Geriatric consult evaluations were associated with significantly lower rates of hospital admission and persisted when controlled for age, gender, comorbidities, and ED observation unit placement. This model may allow healthcare systems to decrease potentially avoidable hospital admission rates in older ED patients.

Do patient-reported outcome measures improve after aseptic revision total hip arthroplasty?

BACKGROUND

The purpose of this study was to determine patient-reported outcome measures (PROMs) changes in: (1) pain, function and global health; and (2) predictors of PROMs in patients undergoing aseptic revision total hip arthroplasty (rTHA) using a multilevel model with patients nested within surgeon.

METHODS

A prospective cohort of 216 patients with baseline and 1-year PROMs who underwent aseptic rTHA between January 2016 and December 2017 were analysed. The most common indication for rTHA was aseptic loosening, instability, and implant failure. The PROMs included in this study were HOOS Pain and HOOS Physical Function Short-form (PS), Veterans RAND-12 Physical Component Score (VR-12 PCS), and VR-12 Mental Component Score (MCS). Multivariable linear regression models were constructed for predicting 1-year PROMs.

RESULTS

Mean 1-year PROMs improvement for aseptic revisions were 30.4 points for HOOS Pain and 22.1 points for HOOS PS. Predictors of better pain relief were patients with higher baseline pain scores. Predictors of better 1-year function were patients with higher baseline function and patients with a posterolateral hip surgical approach during revision. Although VR-12 PCS scores had an overall improvement, nearly 50% of patients saw no improvement or had worse physical component scores. Only 30.7% of patients reported improvements in VR-12 MCS.

CONCLUSIONS

Overall, patients undergoing aseptic rTHA improved in pain and function PROMs at 1 year. Although global health assessment improved overall, nearly half of aseptic rTHA patients reported no change in physical/mental health status. The associations highlighted in this study can help guide the shared decision-making process by setting expectations before aseptic revision THA.

Robotic Arm-Assisted versus Manual Total Knee Arthroplasty: A Propensity Score-Matched Analysis

The purpose of this study was to compare (1) operative time, (2) in-hospital pain scores, (3) opioid medication use, (4) length of stay (LOS), (5) discharge disposition at 90-day postoperative, (6) range of motion (ROM), (7) number of physical therapy (PT) visits, (8) emergency department (ED) visits, (9) readmissions, (10) reoperations, (11) complications, and (12) 1-year patient-reported outcome measures (PROMs) in propensity matched patient cohorts who underwent robotic arm-assisted (RA) versus manual total knee arthroplasty (TKA). Using a prospectively collected institutional database, patients who underwent RA- and manual TKA were the nearest neighbor propensity score matched 3:1 (255 manual TKA:85 RA-TKA), accounting for various preoperative characteristics. Data were compared using analysis of variance (ANOVA), Kruskal-Wallis, Pearson's Chi-squared, and Fisher's exact tests, when appropriate. Postoperative pain scores, opioid use, ED visits, readmissions, and 1-year PROMs were similar between the cohorts. Manual TKA patients achieved higher maximum flexion ROM (120.3 ± 9.9 versus 117.8 ± 10.2, p = 0.043) with no statistical differences in other ROM parameters. Manual TKA had shorter operative time (105 vs.113 minutes, p < 0.001), and fewer PT visits (median [interquartile range] = 10.0 [8.0-13.0] vs. 11.5 [9.5-15.5] visits, p = 0.014). RA-TKA had shorter LOS (0.48 ± 0.59 vs.1.2 ± 0.59 days, p < 0.001) and higher proportion of home discharges (p < 0.001). RA-TKA and manual TKA had similar postoperative complications and 1-year PROMs. Although RA-TKA patients had longer operative times, they had shorter LOS and higher propensity for home discharge. In an era of value-based care models and the steady shift to outpatient TKA, these trends need to be explored further. Long-term and randomized controlled studies may help determine potential added value of RA-TKA versus manual TKA. This study reflects level of evidence III.

Effect of a Medication Disposal Pouch versus Usual Care on Post Discharge Disposal of Unused Opioids: A Randomized Controlled Trial

PURPOSE

To determine frequency of disposal of unused opioids after surgical procedures based on medication disposal pouch use or usual care, and patient factors associated with disposal.

DESIGN

Two-group experimental design and convenience sample.

METHODS

Same-day surgery adults who received opioid orders were randomized to usual care or usual care plus a medication disposal pouch for opioid disposal. Opioid disposal and pain characteristics were collected by telephone at 30±10 days post discharge. Other data were abstracted from a hospital database. Data were compared using Kruskal-Wallis, Pearson's Chi-Square and Fisher's exact tests. Logistic regression models were built to identify predictors of disposal of unused opioids.

FINDINGS

Of 221 adults, mean age was 58.5 years and 50.2% were female. Overall, 121 received medication disposal pouches and 100 received usual care. Among those with a filled prescription, there was no between-group difference in the number of patients who used all of their opioid medication (disposal pouch group, 29.5%; usual care group, 21.7%). Of 74 disposal pouch and 65 usual care patients who did not use all opioid medications, 23.0% and 13.8%, respectively, disposed of opioids, and of the 23.0% of patients who disposed of medications in the disposal pouch group, 94.1% used the medication disposal pouch. After controlling for 7 factors, the odds of disposal of unused opioids increased among patients who received the intervention, had lower pain scores on the worst day of postoperative pain, and had a history of renal diagnoses (versus those with gastrointestinal diagnoses).

CONCLUSIONS

Although opioid medication disposal rates were higher in the medication disposal pouch group; overall rates of disposal of unused opioid medications were low. More research is needed to learn important factors and methods associated with opioid disposal.

Posteromedial Tibial Bone Bruise After Anterior Cruciate Ligament Injury: An MRI Study of Bone Bruise Patterns in 208 Patients

Background:

Bone bruise patterns after anterior cruciate ligament (ACL) rupture may predict the presence of intra-articular pathology and help explain the mechanism of injury. Lateral femoral condyle (LFC) and lateral tibial plateau (LTP) bone bruises are pathognomic to ACL rupture. There is a lack of information regarding medial tibial plateau (MTP) and medial femoral condyle (MFC) bone bruises.

Purpose:

To summarize the prevalence and location of MTP bone bruises with acute ACL rupture and to determine the predictors of MTP bone bruises.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

Inclusion criteria were patients who underwent ACL reconstruction between February 2015 and November 2017, magnetic resonance imaging (MRI) within 90 days of injury, and participation in the database. Exclusion criteria included previous ipsilateral surgery, multiligamentous injuries, and incomplete imaging. Due to the large number of cases remaining (n = 600), 150 patients were selected randomly from each year included in the study, for a total of 300 patients. Two readers independently reviewed injury MRI scans using the Costa-Paz bone bruise grading system. Logistic regression was used to identify factors associated with MTP bone bruises.

Results:

Included were 208 patients (mean age, 23.8 years; mean body mass index, 25.6). The mechanism of injury was noncontact in 59% of injuries, with over half from soccer, basketball, and football. The median time from injury to MRI scan was 12 days. Of the 208 patients, 98% (203/208) had a bone bruise, 79% (164/208) had an MTP bone bruise, and 83% (172/208) had bruises in both medial and lateral compartments. The most common pattern, representing 46.6% of patients (97/208), was a bruise in all 4 locations (MFC, LFC, MTP, and LTP). Of the 164 MTP bruises, 160 (98%) involved the posterior third of the plateau, and 161 were grade 1. The presence of an MFC bruise was the only independent risk factor for an MTP bruise (odds ratio, 3.71). The resulting nomogram demonstrated MFC bruise, sport, and mechanism of injury were the most important predictors of an MTP bruise.

Conclusion:

MTP bruise after acute ACL rupture was as prevalent as lateral bruises. The presence of a posterior MTP bruise suggested anterior tibial translation at the time of injury and could portend more medial compartment pathology at the time of injury than previously recognized.

Evaluation of Health Care Disparities in Patients With Anterior Cruciate Ligament Injury: Does Race and Insurance Matter?

Background:

It is unknown whether race- or insurance-based disparities in health care exist regarding baseline knee pain, knee function, complete meniscal tear, or articular cartilage damage in patients who undergo anterior cruciate ligament reconstruction (ACLR).

Hypothesis:

Black patients and patients with Medicaid evaluated for ACLR would have worse baseline knee pain, worse knee function, and greater odds of having a complete meniscal tear.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

A cohort of patients (N = 1463; 81% White, 14% Black, 5% Other race; median age, 22 years) who underwent ACLR between February 2015 and December 2018 was selected from an institutional database. Patients who underwent concomitant procedures and patients of undisclosed race or self-pay status were excluded. The associations of race with preoperative Knee injury and Osteoarthritis Outcome Score (KOOS) Pain subscale, KOOS Function subscale, and intraoperatively assessed complete meniscal tear (tear that extended through both the superior and the inferior meniscal surfaces) were determined via multivariate modeling with adjustment for age, sex, insurance status, years of education, smoking status, body mass index (BMI), meniscal tear location, and Veterans RAND 12-Item Health Survey Mental Component Score (VR-12 MCS).

Results:

The 3 factors most strongly associated with worse KOOS Pain and KOOS Function were lower VR-12 MCS score, increased BMI, and increased age. Except for age, the other two factors had an unequal distribution between Black and White patients. Univariate analysis demonstrated equal baseline median KOOS Pain scores (Black, 72.2; White, 72.2) and KOOS Function scores (Black, 68.2; White, 68.2). After adjusting for confounding variables, there was no significant difference between Black and White patients in KOOS Pain, KOOS Function, or complete meniscal tears. Insurance status was not a significant predictor of KOOS Pain, KOOS Function, or complete meniscal tear.

Conclusion:

There were clinically significant differences between Black and White patients evaluated for ACLR. After accounting for confounding factors, no difference was observed between Black and White patients in knee pain, knee function, or complete meniscal tear. Insurance was not a clinically significant predictor of knee pain, knee function, or complete meniscal tear.

Should an Age Cutoff Be Considered for Elective Total Knee Arthroplasty Patients? An Analysis of Operative Success Based on Patient-Reported Outcomes

Total knee arthroplasty (TKA) is increasing in the elderly population; however, some patients, family members, and surgeons raise age-related concerns over expected improvement and risks. This study aimed to (1) evaluate the relationship between age and change in patient-reported outcome measures (PROMs); (2) model how many patients would be denied improvements in PROMs if hypothetical age cutoffs were implemented; and (3) assess length of stay (LOS), readmission, reoperation, and mortality per age group. A prospective cohort of 4,396 primary TKAs (August 2015-August 2018) was analyzed. One-year PROMs were evaluated via Knee injury and Osteoarthritis Outcome Score (KOOS)-pain, -physical function short form (-PS), and -quality of life (-QOL), as well as Veterans Rand-12 (VR-12) physical (-PCS) and mental component (-MCS) scores. Positive predictive values (PPVs) of the number of postoperative "failures" (i.e., unattained minimal clinically important difference in PROMs) relative to number of hypothetically denied "successes" from a theoretical age-group restriction was estimated. KOOS-PS and QOL median score improvements were equivalent among all age groups (p = 0.946 and p = 0.467, respectively). KOOS-pain improvement was equivalent for ≥80 and 60-69-year groups (44.4 [27.8-55.6]). Median VR-12 PCS improvements diminished as age increased (15.9, 14.8, and 13.4 for the 60-69, 70-79, and ≥80 groups, respectively; p = 0.002) while improvement in VR-12 MCS was similar among age groups (p = 0.440). PPV for failure was highest in the ≥80 group, yet remained <34% for all KOOS measures. Overall mortality was highest in the ≥80 group (2.14%, n = 9). LOS >2, non-home discharge, and 90-day readmission were highest in the ≥80 group (8.11% [n = 24], p < 0.001; 33.7% [n = 109], p < 0.001; and 34.4% [n = 111], p = 0.001, respectively). Elderly patients exhibited similar improvement in PROMs to younger counterparts despite higher LOS, non-home discharge, and 90-day readmission. Therefore, special care pathways should be implemented for those age groups.

Opioid Use After Simple Arthroscopic Knee Surgery

BACKGROUND

Evidence-based prescribing guidelines are lacking for opioids after most orthopaedic surgical procedures.

HYPOTHESIS

Opioids are commonly overprescribed after simple knee arthroscopy.

STUDY DESIGN

Case-control study; Level of evidence, 3.

METHODS

A cohort of 174 patients who underwent simple arthroscopic knee surgery were prospectively evaluated using data from the Outcome Management and Evaluation database. All patients received 10 combined hydrocodone 5 mg and acetaminophen 325 mg pills postoperatively. Patients were excluded if they (1) had revision surgery, (2) had concomitant complex surgery (eg, ligament surgery, osteotomy), (3) had current opioid use, (4) had open surgery for removal of hardware, (5) or had bilateral knee surgery. Total opioid consumption was reported at the first postoperative visit, and a distribution was created based on patient response. Based on the distribution, patients were separated into low (0-2 pills) versus high (3 or more pills) opioid consumption groups for evaluating risk factors for opioid use. The risk factors included were age, body mass index, smoking status, education level, baseline pain (Knee injury and Osteoarthritis Outcome Score pain subscale [KOOS Pain]), and baseline mental health (Veterans RAND 12-Item Health Survey Mental Component Score), as well as intraoperative findings such as synovial characteristics and extent of osteoarthritis in the multivariate model.

RESULTS

Total opioid consumption ranged from 0 to 19 pills. The median pill count was 2 (25th; 75th interquartile range, 0; 4). Of total patients, 59% were categorized as having low opioid consumption, and the remaining 41% were in the high opioid consumption group. Only 23 patients (13.2%) took 6 or more pills. Preoperative pain as measured by KOOS Pain score was a significant predictor of high opioid consumption postoperatively (odds ratio, 0.97; 95% CI, 0.95-0.99; P = .003).

CONCLUSION

The clinically relevant conclusion is that opioids are overprescribed after simple arthroscopic knee surgery. Based on distribution, the authors recommend that 4 pills be prescribed after simple arthroscopic knee surgery. After accounting for confounding variables, preoperative pain was associated with higher postoperative opioid consumption.

Meniscal Treatment as a Predictor of Worse Articular Cartilage Damage on MRI at 2 Years After ACL Reconstruction: The MOON Nested Cohort

BACKGROUND

Patients undergoing anterior cruciate ligament reconstruction (ACLR) are at an increased risk for posttraumatic osteoarthritis (PTOA). While we have previously shown that meniscal treatment with ACLR predicts more radiographic PTOA at 2 to 3 years postoperatively, there are a limited number of similar studies that have assessed cartilage directly with magnetic resonance imaging (MRI).

HYPOTHESIS

Meniscal repair or partial meniscectomy at the time of ACLR independently predicts more articular cartilage damage on 2- to 3-year postoperative MRI compared with a healthy meniscus or a stable untreated tear.

STUDY DESIGN

Cohort study; Level of evidence, 2.

METHODS

A consecutive series of patients undergoing ACLR from 1 site within the prospective, nested Multicenter Orthopaedic Outcomes Network (MOON) cohort underwent bilateral knee MRI at 2 to 3 years postoperatively. Patients were aged <36 years without previous knee injuries, were injured while playing sports, and had no history of concomitant ligament surgery or contralateral knee surgery. MRI scans were graded by a board-certified musculoskeletal radiologist using the modified MRI Osteoarthritis Knee Score (MOAKS). A proportional odds logistic regression model was built to predict a MOAKS-based cartilage damage score (CDS) relative to the contralateral control knee for each compartment as well as for the whole knee, pooled by meniscal treatment, while controlling for sex, age, body mass index, baseline Marx activity score, and baseline operative cartilage grade. For analysis, meniscal injuries surgically treated with partial meniscectomy or meniscal repair were grouped together.

RESULTS

The cohort included 60 patients (32 female; median age, 18.7 years). Concomitant meniscal treatment at the time of index ACLR was performed in 17 medial menisci (13 meniscal repair and 4 partial meniscectomy) and 27 lateral menisci (3 meniscal repair and 24 partial meniscectomy). Articular cartilage damage was worse in the ipsilateral reconstructed knee (P < .001). A meniscal injury requiring surgical treatment with ACLR predicted a worse CDS for medial meniscal treatment (medial compartment CDS: P = .005; whole joint CDS: P < .001) and lateral meniscal treatment (lateral compartment CDS: P = .038; whole joint CDS: P = .863). Other predictors of a worse relative CDS included age for the medial compartment (P < .001), surgically observed articular cartilage damage for the patellofemoral compartment (P = .048), and body mass index (P = .007) and age (P = .020) for the whole joint.

CONCLUSION

A meniscal injury requiring surgical treatment with partial meniscectomy or meniscal repair at the time of ACLR predicted worse articular cartilage damage on MRI at 2 to 3 years after surgery. Further research is required to differentiate between the effects of partial meniscectomy and meniscal repair.

Risk factors that predict delayed seizure detection on continuous electroencephalogram (cEEG) in a large sample size of critically ill patients

OBJECTIVE

Majority of seizures are detected within 24 hours on continuous EEG (cEEG). Some patients have delayed seizure detection after 24 hours. The purpose of this research was to identify risk factors that predict delayed seizure detection and to determine optimal cEEG duration for various patient subpopulations.

METHODS

We retrospectively identified all patients ≥18 years of age who underwent cEEG at Cleveland clinic during calendar year 2016. Clinical and EEG data for all patients and time to seizure detection for seizure patients were collected.

RESULTS

Twenty-four hundred and two patients met inclusion criteria. Of these, 316 (13.2%) had subclinical seizures. Sixty-five (20.6%) patients had delayed seizures detection after 24 hours. Seizure detection increased linearly till 36 hours of monitoring, and odds of seizure detection increased by 46% for every additional day of monitoring. Delayed seizure risk factors included stupor (13.2% after 48 hours, P = .031), lethargy (25.9%, P = .013), lateralized (LPDs) (27.7%, P = .029) or generalized periodic discharges (GPDs) (33.3%, P = .022), acute brain insults (25.5%, P = .036), brain bleeds (32.8%, P = .014), especially multiple concomitant bleeds (61.1%, P < .001), altered mental status (34.7%, P = .001) as primary cEEG indication, and use of antiseizure medications (27.8%, P < .001) at cEEG initiation.

SIGNIFICANCE

Given the linear seizure detection trend, 36 hours of standard monitoring appears more optimal than 24 hours especially for high-risk patients. For awake patients without epileptiform discharges, <24 hours of monitoring appears sufficient. Previous studies have shown that coma and LPDs predict delayed seizure detection. We found that stupor and lethargy were also associated with delayed seizure detection. LPDs and GPDs were associated with delayed seizures. Other delayed seizure risk factors included acute brain insults, brain bleeds especially multiple concomitant bleeds, altered mental status as primary cEEG indication, and use of ASMs at cEEG initiation. Longer cEEG (≥48 hours) is suggested for these high-risk patients.

Evaluation of Differences Between Non-Hispanic White and African American Patients With Sports Medicine–Related Hip Disabilities

Background:

Racial disparities within the field of orthopaedics are well-documented in the spinal surgery, knee arthroplasty, and hip arthroplasty literature. Not much is known about racial differences in patients with sports medicine–related hip disabilities.

Purpose:

To investigate whether differences exist between African American and non-Hispanic White (White) patients evaluated for hip disabilities.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

We performed a multicenter retrospective cohort study of 905 patients who were evaluated over a 1-year period for hip-related orthopaedic concerns. Patient demographic data, disability characteristics, and hip radiographic findings were obtained from electronic medical records. We also obtained data on whether patients were offered physical therapy, magnetic resonance imaging (MRI), and/or surgery. Comparisons by race and insurance status were evaluated using univariate and multivariate analyses.

Results:

African Americans comprised a significantly lower proportion of the patients evaluated for hip-related disabilities compared with Whites (6.5% vs 93.5%; P < .001). A significantly smaller proportion of African Americans with hip disabilities was recommended for surgery than White patients (35.6% vs 54.6%; P = .007). Cam deformities were more common in White vs African American patients (39.7% vs 23.7%; P = .021), as were labral tears (54.1% vs 35.6%; P = .009). Logistic regression demonstrated that neither race nor insurance status were significant determinants in surgery recommendations. Conversely, race was a determinant of whether an MRI was performed, as White patients were 2.74 times more likely to have this procedure. There were no differences with respect to obtaining an MRI between private and Medicaid insurance.

Conclusion:

Compared with White patients, there were differences in both the proportion of African Americans evaluated for hip-related disabilities and the proportion receiving a surgery recommendation. African Americans with sports medicine–related hip issues were also less likely to obtain an MRI. With regard to observed pathology, African American patients were less likely to have cam deformities and labral tears than White patients.

Patient Age and Cell Concentration Influence Prevalence and Concentration of Progenitors in Bone Marrow Aspirates: An Analysis of 436 Patients

BACKGROUND

Connective tissue progenitors (CTPs) resident in native tissues serve as biological building blocks in tissue repair and remodeling processes. Methods for analysis and reporting on CTP quantity and quality are essential for defining optimal cell sources and donor characteristics and the impact of cell processing methods for cell therapy applications. The present study examines the influence of donor characteristics and cell concentration (nucleated cells/mL) on CTP prevalence (CTPs/million nucleated cells) and CTP concentration (CTPs/mL) in bone marrow aspirates (BMAs).

METHODS

Iliac crest bone marrow was aspirated from 436 patients during elective total knee or hip arthroplasty. Bone marrow-derived nucleated cells were plated at a density of 1.19 × 105 cells/cm2. Colony-forming unit analysis was performed on day 6.

RESULTS

Large variation was seen between donors. Age (p < 0.05) and cell concentration (p < 0.001) significantly influenced CTP prevalence and CTP concentration. For every 1-year increase in age, the odds of having at least an average CTP prevalence and CTP concentration decreased by 1.5% and 1.6%, respectively. For every 1 million cells/mL increase in cell concentration, the odds of having at least an average CTP prevalence and CTP concentration increased by 2.2% and 7.9%, respectively. Sex, race, body mass index (BMI), and the presence of osteoporosis did not influence CTP prevalence or CTP concentration.

CONCLUSIONS

BMA-derived CTPs were obtained from all patient groups. CTP prevalence and CTP concentration decreased with age. Cell concentration decreased with age and positively correlated with total CTP prevalence and CTP concentration. The mean CTP concentration in patients >60 years of age was a third of the CTP concentration in patients <30 years of age.

CLINICAL RELEVANCE

Proper BMA techniques are necessary to obtain a high-quality yield and composition of cells and CTPs. The reduced CTP concentration and CTP prevalence in the elderly may be mitigated by the use of cell processing methods that increase CTP concentration and CTP prevalence (e.g., by removing red blood cells, serum, and non-CTPs or by increasing aspirate volumes). Cell concentration in the BMA can be measured at the point of care and is an appropriate initial assessment of the quality of BMA.

Articular Cartilage and Meniscus Predictors of Patient-Reported Outcomes 10 Years After Anterior Cruciate Ligament Reconstruction: A Multicenter Cohort Study

BACKGROUND

Articular cartilage and meniscal damage are commonly encountered and often treated at the time of anterior cruciate ligament reconstruction (ACLR). Our understanding of how these injuries and their treatment relate to outcomes of ACLR is still evolving.

HYPOTHESIS/PURPOSE

The purpose of this study was to assess whether articular cartilage and meniscal variables are predictive of 10-year outcomes after ACLR. We hypothesized that articular cartilage lesions and meniscal tears and treatment would be predictors of the International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS) (all 5 subscales), and Marx activity level outcomes at 10-year follow-up after ACLR.

STUDY DESIGN

Cohort study (prognosis); Level of evidence, 1.

METHODS

Between 2002 and 2008, individuals with ACLR were prospectively enrolled and followed longitudinally using the IKDC, KOOS, and Marx activity score completed at entry, 2, 6, and 10 years. A proportional odds logistic regression model was built incorporating variables from patient characteristics, surgical technique, articular cartilage injuries, and meniscal tears and treatment to determine the predictors (risk factors) of IKDC, KOOS, and Marx outcomes at 10 years.

RESULTS

A total of 3273 patients were enrolled (56% male; median age, 23 years at time of enrollment). Ten-year follow-up was obtained on 79% (2575/3273) of the cohort. Incidence of concomitant pathology at the time of surgery consisted of the following: articular cartilage (medial femoral condyle [MFC], 22%; lateral femoral condyle [LFC], 15%; medial tibial plateau [MTP], 4%; lateral tibial plateau [LTP], 11%; patella, 18%; trochlea, 8%) and meniscal pathology (medial, 37%; lateral, 46%). Variables that were predictive of poorer 10-year outcomes included articular cartilage damage in the patellofemoral (P < .01) and medial (P < .05) compartments and previous medial meniscal surgery (7% of knees; P < .04). Compared with no meniscal tear, a meniscal injury was not associated with 10-year outcomes. Medial meniscal repair at the time of ACLR was associated with worse 10-year outcomes for 2 of 5 KOOS subscales, while a medial meniscal repair in knees with grade 2 MFC chondrosis was associated with better outcomes on 2 KOOS subscales.

CONCLUSION

Articular cartilage injury in the patellofemoral and medial compartments at the time of ACLR and a history of medial meniscal surgery before ACLR were associated with poorer 10-year ACLR patient-reported outcomes, but meniscal injury present at the time of ACLR was not. There was limited and conflicting association of medial meniscal repair with these outcomes.

Association between limiting the number of open records in a tele-critical care setting and retract-reorder errors

BACKGROUND

Wrong patient selection errors may be tracked by retract-reorder (RAR) events. The aim of this quality improvement study was to assess the impact of reducing the number of concurrently open electronic health records from 4 to 2 on RAR errors generated by a tele-critical care service.

METHODS

The study encompassed 32 months before and 21 months after restriction. Chi-Square test of proportions and T statistical process control chart for rare events were used.

RESULTS

There were 156 318 orders with 57 RAR errors (36.5/100 000 orders) before restriction, and 122 587 orders with 34 errors (27.7/100 000 orders) after. Rates were not statistically different (P = .20), but analysis was underpowered. When plotted on a T control chart, random variation was detected between RAR errors.

CONCLUSION

We found no significant difference in RAR errors in the tele-critical care setting after open record limitation. Other strategies should be studied to reduce wrong patient selection errors.

Validation of a Risk Calculator to Personalize Graft Choice and Reduce Rupture Rates for Anterior Cruciate Ligament Reconstruction

BACKGROUND

Anterior cruciate ligament reconstructions (ACLRs) fail at an alarmingly high rate in young active individuals. The Multicenter Orthopaedic Outcomes Network (MOON) knee group has developed an autograft risk calculator that uses patient characteristics and lifestyle to predict the probability of graft rupture if the surgeon uses a hamstring tendon (HT) or a bone-patellar tendon-bone (BPTB) graft to reconstruct the ligament. If validated, this risk calculator can be used during the shared decision-making process to make optimal ACLR autograft choices and reduce rupture rates. The STABILITY 1 randomized clinical trial offers a large, rigorously collected data set of similar young active patients who received HT autograft with or without lateral extra-articular tenodesis (LET) for ACLR.

PURPOSE/HYPOTHESIS

The purpose was to validate the ACLR graft rupture risk calculator in a large external data set and to investigate the utility of BPTB and LET for ACLR. We hypothesized that the risk calculator would maintain adequate discriminative ability and calibration in the external STABILITY 1 data set when compared with the initial MOON development data set.

STUDY DESIGN

Cohort study (diagnosis); Level of evidence, 1.

METHODS

The model predictors for the risk calculator include age, sex, body mass index, sport played at the time of injury, Marx Activity Score, preoperative knee laxity, and graft type. The STABILITY 1 trial data set was used for external validation. Discriminative ability, calibration, and diagnostic test validity of the model were assessed. Finally, predictor strength in the initial and validation samples was compared.

RESULTS

The model showed acceptable discriminative ability (area under the curve = 0.73), calibration (Brier score = 0.07), and specificity (85.3%) to detect patients who will experience a graft rupture. Age, high-grade preoperative knee laxity, and graft type were significant predictors of graft rupture in young active patients. BPTB and the addition of LET to HT were protective against graft rupture versus HT autograft alone.

CONCLUSION

The MOON risk calculator is a valid predictor of ACLR graft rupture and is appropriate for clinical practice. This study provides evidence supporting the idea that isolated HT autografts should be avoided for young active patients undergoing ACLR.

Recurrent Nephritis and/or Pulmonary Hemorrhage in Patients with Anti-Glomerular Basement Membrane Disease with and without ANCA Positivity

Introduction

Anti-glomerular basement membrane (anti-GBM) disease is characterized by rapidly progressive glomerular nephritis with or without pulmonary hemorrhage with disease severity correlating with antibody titer. Following treatment, relapse is rare but has been reported in the literature. The objective of this study was to assess for clinical, serologic, and histologic differences associated with disease relapse in patients with anti-GBM disease.

Methods

Patients seen at our facility between 1997 and 2017 were screened for anti-GBM disease by ICD 9/10 codes. They were included if the diagnosis was confirmed by a board-certified rheumatologist or nephrologist and had positive antibodies and/or biopsy results consistent with anti-GBM disease. Relapsing disease was defined as recurrence of pulmonary or renal manifestations after achieving remission following the initial presentation. All charts were reviewed for baseline demographics, clinical manifestations, and antibody positivity and compared between groups.

Results

40 patients were confirmed as having anti-GBM disease. Mean follow-up from disease onset to the date of last follow-up was 56.2 months. 8 patients had relapsing disease and 32 patients had nonrelapsing disease. Baseline characteristics and clinical manifestations were similar between groups. Patients with relapsing disease had a high incidence of anti-neutrophilic cytoplasmic antibody (ANCA) co-positivity as compared to nonrelapsing patients (50 vs. 15.6%, respectively, p = 0.059), but this did not reach statistical significance. In patients with relapsing disease, only one had positive anti-GBM antibodies at time of relapse.

Conclusions

In this study, patients with relapsing disease had a high incidence of ANCA co-positivity (50%). In patients with newly diagnosed anti-GBM disease, ANCAs should be obtained to assess for the risk of relapse and to help guide long-term follow-up and treatment.

Real-World Treatment Patterns in a Population With Neovascular AMD Treated With Anti-VEGF Agents

BACKGROUND AND OBJECTIVES

To characterize mean number of injections, injection type, and injection frequency during the first year of treatment; assess factors significantly related to injection interval; and identify predictive factors related to patient outcomes.

PATIENTS AND METHODS

A retrospective, noncomparative, nonrandomized cohort study of ocular treatment with intravitreal injections of bevacizumab, ranibizumab, and aflibercept in eyes with neovascular age-related macular degeneration (nAMD). Data from January 1, 2012, through March 31, 2018, were systematically extracted from the electronic medical record system at Cole Eye Institute. Eligible patients had three or more injections within the first 12 months of treatment and received no prior injections.

RESULTS

Patients received an average 8.12 ± 2.45 injections, and 45% of patients received injections at an interval of 8 weeks or less (≤q8 weeks), 33% received injections at 8 to 12 weeks (q8-12 weeks), and 22% received injections at greater than 12 weeks (>q12 weeks). Age (P = .007) and initial central subfield thickness (CST) (P = .043) had statistically significant trend relationships (P = .007) with injection interval, whereas younger patients and patients with higher CST measurements tended to have shorter injection intervals. Injection interval was a significant predictor of visual acuity (VA) and CST. Patients receiving injections at q8-12 weeks were more likely to have better VA outcomes than patients with injection intervals at ≤q8 weeks (odds ratio [OR] = 1.66 [1.16, 2.37]; P = .005). Patients receiving injections at >q12 weeks did not show a significant improvement in VA (P = .06) and were more likely to have worse CST outcomes than patients receiving injections at ≤q8 weeks (OR = 1.95 [1.17, 3.26]; P = .011).

CONCLUSION

A significant portion of patients receive injections at an interval longer than every 8 weeks. Age and baseline CST had a significant relationship with injection interval. Injection interval was a significant predictor of VA and CST at 1 year. Patients with an injection interval of >q12 weeks tended to have less VA improvement and CST reduction compared to the ≤q8 weeks and q8-12 weeks groups. These findings suggest an extended injection interval >q12 weeks may be at the expense of potential VA improvement. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:190-198.].

CONSEQUENCES OF LAPSES IN TREATMENT WITH VASCULAR ENDOTHELIAL GROWTH FACTOR INHIBITORS IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION IN ROUTINE CLINICAL PRACTICE

PURPOSE

Evaluating outcomes in patients receiving intravitreal antivascular endothelial growth factor (VEGF) inhibitors for neovascular age-related macular degeneration whom experience a lapse in treatment.

METHODS

A retrospective chart review evaluating 3,304 patients ≥18 years who experienced treatment lapses ≥3 months compared with control counterparts. Demographic information, macular thickness as measured by central subfield thickness, and visual acuity were collected at baseline, the first postlapse appointment, and at 3, 6, and 12 months after the lapse for the study group.

RESULTS

Lapse (n = 241) and control patients (n = 241) had similar baseline visual acuity and central subfield thickness (Early Treatment Diabetic Retinopathy Study: 58.9 ± 20.2 [20/63] vs. 59.2 ± 20.1 [20/63]; central subfield thickness: 252.4 ± 63.2 µm vs. 259.8 ± 66.2 µm, P = 0.21). Analysis revealed that lapse patients experienced a significant increase in central subfield thickness after lapse when compared with controls (279.4 ± 86.9 µm vs. 253.7 ± 65.9 µm, P < 0.01), which normalized on resumption of treatment (259.1 ± 79 µm vs. 246.8 ± 57.6 µm, P = 0.06). Study patients also experienced loss in the visual acuity after lapse when compared with controls (52.9 ± 23.6 Early Treatment Diabetic Retinopathy Study [20/100] vs. 59.9 ± 20.8 [20/63] Early Treatment Diabetic Retinopathy Study, P < 0.01) that did not recover through 12 months of follow-up.

CONCLUSION

Patients with neovascular age-related macular degeneration who have lapses in care are at risk for poorer outcomes. Although macular thickness normalizes on resumption of treatment, their decline in the visual acuity does not recover.

Association of Unit-Level Telecritical Care Intensity of Service and Length of Stay in the Intensive Care Unit

Background: Telecritical care (TCC) has been shown to improve outcomes in the intensive care unit (ICU). A TCC was developed and implemented a nocturnal TCC across 10 ICUs in our Health System. TCC coverage patterns and level of involvement vary among ICUs. We identified an opportunity to determine the impact of TCC involvement on the ICU length of stay (LOS). Objective: The primary objective of this study was to assess if intensity of service provided by TCC impacts ICU LOS. Methods: This retrospective review was conducted for all patients admitted to covered ICUs during a 2-year period. ICUs were stratified by the coverage model provided by the TCC and the count of orders placed by the TCC served as a surrogate for intensity of service. Confounding variables were abstracted from the Acute Physiology and Chronic Health Evaluation (APACHE) databases. Spearman's rank correlation coefficient was used to measure the strength of the relationship between ICU LOS and TCC order volume. A linear regression model was used to describe the relationship between order volume and ICU LOS, while adjusting for confounding variables. Results: There is a strong negative relationship between TCC order volume and ICU LOS, as shown by the Spearman rank correlation coefficient of -0.818. The associated p-value of 0.0038 supports the strength of this relationship. Conclusion: Our results demonstrate the impact of nocturnal TCC involvement in patient care. As TCC order volume per ICU admission increases, ICU LOS decreases. We interpret this as an indication for deeper involvement between the TCC team and any on-site providers.

Interrater Agreement of an Arthroscopic Anterior Cruciate Ligament Tear Classification System

Background

Anterior cruciate ligament (ACL) rupture is the most common ligament injury treated surgically by orthopaedic surgeons. The gold standard for the treatment of the majority of primary ACL tears is ACL reconstruction. However, novel methods of repair, such as bridge-enhanced ACL repair (BEAR), are currently being investigated as alternatives to reconstruction. To assess patients for midsubstance repair suitability, clarify the prognostic implications of injury location and damage, and evaluate the results of a repair technique, it is important to have a baseline classification system or grading scale that is reproducible across surgeons, particularly for multicenter collaboration. Currently, no such system or scale exists.

Purpose

To develop an arthroscopic ACL tear classification system and to evaluate its interobserver reliability.

Study Design

Cohort study (diagnosis); Level of evidence, 3.

Methods

Eleven fellowship-trained orthopaedic surgeon investigators reviewed 75 video clips containing arthroscopic evaluation of a torn ACL and then completed the 6-question ACL Pathology Evaluation Form. Agreement statistics including exact agreement, Fleiss κ, Gwet agreement coefficient 1 (AC1), and Gwet AC2 were then calculated to assess interobserver reliability.

Results

In aggregate, the multiple assessments of observer reproducibility revealed that surgeon participants in this study, when evaluating the same injury, agreed roughly 80% of the time on whether (1) at least 50% of the tibial footprint remained, (2) the remaining tibial stump was ≥10 mm, and (3) the injury was therefore reparable using the BEAR procedure. Participants also agreed roughly 60% of the time on exactly how many suturable bundles were available. These characteristics are believed to be most important, among those studied, in determining whether a torn ACL is amenable to midsubstance repair.

Conclusion

This study is the first of its kind to demonstrate the interobserver reliability of arthroscopic classification of ACL tears. We have demonstrated that this classification system, though not ideally reproducible, is reliable enough across surgeons at multiple institutions for use in multicenter studies.

Procedural frequency: Results from 18 academic, community and freestanding emergency departments

BACKGROUND

Emergency physicians must maintain procedural skills, but clinical opportunities may be insufficient. We sought to determine how often practicing emergency physicians in academic, community and freestanding emergency departments (EDs) perform 4 procedures: central venous catheterization (CVC), tube thoracostomy, tracheal intubation, and lumbar puncture (LP).

METHODS

This was a retrospective study evaluating emergency physician procedural performance over a 12-month period. We collected data from the electronic records of 18 EDs in one healthcare system. The study EDs included higher and lower volume, academic, community and freestanding, and trauma and non-trauma centers. The main outcome measures were median number of procedures performed. We examined differences in procedural performance by physician years in practice, facility type, and trauma status.

RESULTS

Over 12 months, 182 emergency physicians performed 1582 of 2805 procedures (56%) and supervised (resident, nurse practitioner or physician assistant) an additional 1223 of the procedures they did not perform (43%). Median (interquartile range) physician performance for each procedure was CVC 0 [0, 2], tube thoracostomy 0 [0, 0], tracheal intubation 3 [0.25, 8], and LP 0 [0, 2]. The percentage of emergency physicians who did not perform at least one of each procedure during the 1-year time frame ranged from 25.3% (tracheal intubation) to 76.4% (tube thoracostomy). Physicians who work at high-volume EDs (>50,000 visits per year) performed nearly twice as many tracheal intubations, CVCs, and LPs than those at low-volume EDs or freestanding EDs when normalized per 1000 visits. Years out of training were inversely related to total number of procedures performed. Emergency physicians at trauma centers performed almost 3 times as many tracheal intubations and almost 4 times as many CVCs compared to non-trauma centers.

CONCLUSION

In a large healthcare system, regardless of ED type, emergency physicians infrequently performed the 4 procedures studied. Physicians in high-volume EDs, trauma centers, and recent graduates performed more procedures. Our study adds to a growing body of research that suggests clinical frequency alone may be insufficient for all emergency physicians to maintain competency.

The impact of hospital boarding on the emergency department waiting room

BACKGROUND

Patient boarding in the emergency department (ED) is a significant issue leading to increased morbidity/mortality, longer lengths of stay, and higher hospital costs. We examined the impact of boarding patients on the ED waiting room. Additionally, we determined whether facility type, patient acuity, time of day, or hospital occupancy impacted waiting rooms in 18 EDs across a large healthcare system.

METHODS

This was a retrospective multicenter study that included all ED encounters between January 1, 2018, and September 30, 2019. Encounters with missing Emergency Severity Index (ESI) level were excluded. ESI levels were defined as high (ESI 1,2), middle (ESI 3), and low (ESI 4,5). Spearman correlation coefficients measured the relationship between boarded patients and number of patients in ED waiting room. A multivariable mixed effects model identified drivers of this relationship.

RESULTS

A total of 1,134,178 encounters were included. Spearman correlation coefficient was significant between number of patients in the ED waiting room and patient boarding (0.54). For every additional patient boarded/hour, the number of patients waiting/hour in the waiting room increased by 8% (95% confidence interval [CI] = 1.08-1.09). The number of patients waiting for a room/hour was 2.28 times higher for middle than for high acuity. The number of patients in waiting room slightly decreased as hospital occupancy increased (95% CI = 0.997-0.997).

CONCLUSION

Number of patients in ED waiting room are directly related to boarding times and hospital occupancy. ED waiting room times should be considered as not just an ED operational issue, but an aspect of hospital throughput.

Predictors of extensive subclinical spread in squamous cell carcinoma

e22093

Background: Extensive spread of squamous cell carcinoma (SCC) is often clinically imperceptible but has a profound impact on risk of recurrence and metastasis. Accurate identification of high-risk SCC enables educated choices in treatment modality and appropriate referrals for Mohs micrographic surgery (MMS). Methods: We conducted a retrospective cohort study of 1,019 patients with SCC removal by MMS at the Cleveland Clinic. We analyzed the relationship between various patient and tumor characteristics to aggressive subclinical extension (ASE), defined as tumors requiring >3 Mohs layers to obtain clear margins. Tumor locations were grouped into zones according to the American Academy of DermatologyÕs appropriate use criteria (AUC). Results: 67 of 1,149 tumors required >3 Mohs layers for removal. Tumor grade was the only statistically significant variable, with moderately-differentiated tumors having 1.828 times the odds of ASE compared to well-differentiated tumors (95% CI = [1.026, 3.255], p = 0.041). Poorly-differentiated tumors had 4.273 times the odds of ASE compared to well-differentiated tumors (95% CI = [1.755, 10.4], p = 0.001). Conclusions: Current treatment guidelines for SCC are largely derived from data on all non-melanoma skin cancers. SCC is associated with higher metastatic potential than basal cell carcinoma (BCC), emphasizing the importance of independent analysis of SCC. The power of this study was limited by the small number of extensively spread tumors. Despite this limitation, our analysis shows poorly and moderately-differentiated tumors are correlated with a higher rate of ASE compared to well-differentiated tumors. Moderately-differentiated tumor grade is not included in the AUC, however treatment of these tumors with MMS might improve patient outcomes and minimize costs associated with recurrence. Our results show risk stratification by zone has minimal utility in identifying ASE-SCC. Improved understanding of location-based differences in tumor behavior could reveal discrepancies between SCC and BCC, enabling revised zones specific to SCC. [Table: see text]

Determinants and outcome of repeat continuous electroencephalogram monitoring-A case-control study

OBJECTIVE

A retrospective, single-center study to analyze the determinants of a repeat continuous EEG (cEEG) monitoring during hospitalization and its outcomes using a matched case-control study design.

METHODS

Adults with a repeat cEEG session (cases) were matched by age (±3 years), gender, and mental status to patients with a single cEEG (controls) during hospitalization. Several clinical and EEG characteristics were analyzed to identify predictors of repeat cEEG. Repeat cEEG outcomes were analyzed based on its yield of electrographic seizure. We investigated the predictors of finding increased epileptic potential (degree of association with electrographic seizures) on the repeat cEEG, a marker for possible anti-epileptic drugs (AEDs) management change.

RESULTS

A total of 213 (8.6% of all unique cEEG patients) cases were included. A multivariable conditional logistic regression model comparing cases and controls showed that the presence of acute brain insult [odds ratio (OR) = 3.36, 95% CI = 1.26-8.94, P = .015], longer hospital admission (OR = 1.11, 95% CI = 1.07-1.15, P < .001) and being on AEDs at the end of index cEEG (OR = 4.0, 95% CI = 1.8-8.87, P < .001) was determinants of a repeat cEEG. Among cases, 17 (8%) had electrographic seizures on repeat cEEG. Increased epileptic potential on repeat cEEG was noted in 34 (16%) cases. The latter is associated with change in etiology after the index cEEG (P = .03) and duration of repeat cEEG (P = .003) based on multivariable logistic regression model. AEDs were changed in 46 (21.6%) patients based on repeat cEEG findings.

SIGNIFICANCE

Repeat cEEG is not an uncommon practice. It leads to the diagnosis of electrographic seizures in a significant percentage of patients. With the potential of impacting AED management in 16%-21% patients, it should be considered in high-risk patients suffering acute brain insults undergoing prolonged hospitalization.
