30-day Emergency Department Visits Research Articles

Socioeconomic factors including patient income, education level and health insurance influence post-operative secondary surgery and hospitalization rates following hip arthroscopy

To evaluate a large cross-sectional sample of patients utilizing administrative database records, and analyze the effects of income, insurance type, and education level on outcomes after hip arthroscopy, including 2-year revision surgery, conversion to total hip arthroplasty (THA) and 90-day hospitalizations. Current Procedural Terminology codes were used to query the PearlDiverTM Mariner database from October 2015 to January 2020 for patients undergoing hip arthroscopy with minimum 2-year follow-up. Patients were categorized by mean family income in their zip code of residence (MFIR), health insurance type, and educational attainment in their zip code of residence (EAR). 2-year revision arthroscopy, conversion to THA and 90-day hospital readmissions or emergency department (ED) visits were analyzed along socioeconomic strata. Multivariate analysis of 33,326 patients revealed that patients with MFIR between $30,000-$70,000 had lower odds of 2-year revision arthroscopy [OR = 0.63, p < 0.001], THA conversion [OR= 0.76, p= 0.050], and 90-day readmission [OR= 0.53, p= 0.007] compared to MFIR >$100,000. Compared to patients with commercial insurance, patients with Medicare had lower odds of revision arthroscopy [OR= 0.60, p= 0.035] and THA conversion [OR= 0.46, p< 0.001], but greater odds of 90-day readmission [OR= 1.74, p= 0.007]. Patients with Medicaid had higher odds of 90-day ED visits [OR= 1.84, p< 0.001]. Patients with low EAR had higher odds of revision arthroscopy [OR= 1.42, p= 0.005] and THA conversion [OR= 1.58, p= 0.002] compared to those with high EAR. Following hip arthroscopy, patients residing in areas with lower mean family income were less likely to undergo reoperations and readmissions. Medicare patients showed lower reoperation but higher readmission odds, while Medicaid patients showed higher odds of ED visits. Additionally, higher educational attainment in the zip code of residence is protective against future reoperation. Level III. Retrospective Case Series.

Revision Total Knee Arthroplasty in an Outpatient Setting: A Growing Alternative

IntroductionRecent studies have focused on the safety and efficacy of performing primary total knee arthroplasty (TKA) in an outpatient setting. Despite being associated with greater costs, much less is known about the accompanying impact on revision TKA (rTKA). The purpose of this study was to describe the trends in costs and outcomes of patients undergoing inpatient and outpatient rTKA. MethodsAn observational cohort study was conducted using commercial claims databases. Patients who underwent one- and two-component rTKA in an inpatient setting, hospital-based outpatient department (HOPD), or ambulatory surgery center (ASC) from 2018 to 2020 were included. The primary outcome was the 30-day episode of care costs following rTKA. Secondary outcomes included surgical cost, 90-day readmission rate, and emergency department (ED) visit rate. Covariates for analyses included patient demographics, surgery type, and indication for revision. ResultsThere were 6,515 patients who were identified, with 17.0% of rTKAs taking place in an outpatient setting. On adjusted analysis, patients in the highest quartile of 30-day postoperative costs were more likely to be those whose rTKA was performed in an inpatient setting. One-component revisions were more common in an outpatient setting (HOPD, 50.7%; ASC, 62.0%) compared to an inpatient setting (39.6%). The 90-day readmission rates were higher (P = 0.003) for rTKAs performed in inpatient (+9.2%) and HOPD (+8.6%) settings compared to those in an ASC. ConclusionThe ASC may be a suitable setting for simpler revisions performed for less severe indications and is associated with lower costs and 90-day readmission and ED visit rates.

Hypogonadism, frailty, and postoperative outcomes among men undergoing radical nephrectomy.

Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN. Length of stay (LOS), complications, emergency department (ED) visits, and readmissions were evaluated between men with and without hypogonadism at the time of surgery. Subgroup analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. Among 13 598 men who underwent RN, 972 (7.1%) had hypogonadism. Men with hypogonadism were more frail compared to men without hypogonadism (HFRS: median: 8.2, interquartile range [IQR]: 5.2-11.7 vs. median: 7.0, IQR: 4.3-10.7, p < 0.001) and had increased incidence of postoperative ileus (13.0% vs. 10.8%, p = 0.045), acute kidney injury (25.5% vs. 21.6% p = 0.005), and cardiac arrest (1.2% vs. 0.6%, p = 0.034). Hypogonadism was not associated with LOS, 90-day ED visit or readmission. However, high-risk frailty was associated with increased risk of 90-day ED visit (hazard ratio [HR]: 2.1, 95% confidence interval [95% CI]: 1.9-2.4, p < 0.001) and 90-day inpatient readmission (HR: 2.6, 95% CI: 2.2-3.1, p < 0.001), compared to low-risk frailty patients. Among men with hypogonadism, TRT was not associated with any postoperative outcomes. Hypogonadism and frailty should be considered in the preoperative evaluation for men undergoing RN as risk factors for adverse postoperative outcomes.

Evacuation and Health Care Outcomes Among Assisted Living Residents After Hurricane Irma

Evacuation has been found to be associated with adverse outcomes among nursing home residents during hurricanes, but the outcomes for assisted living (AL) residents remain unknown. To examine the association between evacuation and health care outcomes (ie, emergency department visits, hospitalizations, mortality, and nursing home visits) among Florida AL residents exposed to Hurricane Irma. Retrospective cohort study using 2017 Medicare claims data. Participants were a cohort of Florida AL residents who were aged 65 years or older, enrolled in Medicare fee-for-service, and resided in 9-digit zip codes corresponding to US assisted living communities with 25 or more beds on September 10, 2017, the day of Hurricane Irma's landfall. Propensity score matching was used to match evacuated residents to those that sheltered-in-place based on resident and AL characteristics. Data were analyzed from September 2022 to February 2024. Whether the AL community evacuated or sheltered-in-place before Hurricane Irma made landfall. Thirty- and 90-day emergency department visits, hospitalizations, mortality, and nursing home admissions. The study cohort included 25 130 Florida AL residents (mean [SD] age 81 [9] years); 3402 (13.5%) evacuated and 21 728 (86.5%) did not evacuate. The evacuated group had 2223 women (65.3%), and the group that sheltered-in-place had 14 556 women (67.0%). In the evacuated group, 42 residents (1.2%) were Black, 93 (2.7%) were Hispanic, and 3225 (94.8%) were White. In the group that sheltered in place, 490 residents (2.3%) were Black, 707 (3.3%) were Hispanic, and 20 212 (93.0%) were White. After 1:4 propensity score matching, when compared with sheltering-in-place, evacuation was associated with a 16% greater odds of emergency department visits (adjusted odds ratio [AOR], 1.16; 95% CI, 1.01-1.33; P = .04) and 51% greater odds of nursing home visits (AOR, 1.51; 95% CI, 1.14-2.00; P = .01) within 30 days of Hurricane Irma's landfall. Hospitalization and mortality did not vary significantly by evacuation status within 30 or 90 days after the landfall date. In this cohort study of Florida AL residents, there was an increased risk of nursing home and emergency department visits within 30 days of Hurricane Irma's landfall among residents from communities that evacuated before the storm when compared with residents from communities that sheltered-in-place. The stress and disruption caused by evacuation may yield poorer immediate health outcomes after a major storm for AL residents. Therefore, the potential benefits and harms of evacuating vs sheltering-in-place must be carefully considered when developing emergency planning and response.

Revisiting the Association of ECOG Performance Status With Clinical Outcomes in Diverse Patients With Cancer.

The ECOG performance status (PS) scale was developed to support national clinical trials, but the degree to which ECOG PS predicts clinical outcomes in patient subgroups outside of clinical trials is relatively unknown. This study examined associations between ECOG PS and adverse outcomes in a diverse community oncology population. In this retrospective cohort study, demographic and clinical characteristics, including the most recent ECOG PS between January 1, 2017, and December 31, 2019, were examined for patients receiving cancer treatment within Kaiser Permanente Northern California (KPNC). Proportional hazard models were used to evaluate the effect of ECOG PS on adverse outcomes. A total of 21,730 patients were identified. Overall, most patients had an ECOG PS of 0 (42.5%) or 1 (42.5%). In multivariable analysis, an ECOG PS of 3 or 4 was associated with higher risk of 30-day emergency department visits (adjusted hazard ratio [aHR], 3.85; 95% CI, 3.47-4.26), 30-day hospitalizations (aHR, 4.70; 95% CI, 4.12-5.36), and 6-month mortality (aHR, 7.34; 95% CI, 6.64-8.11) compared with an ECOG PS of 0. Additionally, we found that upper gastrointestinal and stage IV cancers were associated with a higher risk of adverse outcomes compared with breast and stage I cancers, respectively. When adjusted for ECOG PS, African American race, Asian race, and female sex were associated with a lower risk of mortality than White race and male sex. An ECOG PS of 3 or 4 was more predictive of mortality in younger patients and those with breast cancer (P<.001). ECOG PS and upper gastrointestinal and stage IV cancers were independently associated with increased risk of emergency department visits, hospitalizations, and mortality, whereas African American and Asian race and female sex were associated with decreased risk of mortality. An ECOG PS of 3 or 4 was more predictive of an increased risk of mortality in younger patients and patients with breast cancer. These findings can enhance the use of ECOG PS for clinical decision-making and defining eligibility for clinical trials.

Impact of surgeon volume, experience, and training on outcomes after arthroscopic rotator cuff repair: a nationwide analysis of 1489 surgeons

BackgroundGiven the complexity of arthroscopic rotator cuff repair (ARCR) and increasing prevalence, there is a need for comprehensive, large-scale studies that investigate potential correlations between surgeon-specific factors and postoperative outcomes after ARCR. This study examines how surgeon-specific factors including case volume, career length, fellowship training, practice setting, and regional practice impact two-year reoperation rates, conversion to total shoulder arthroplasty (anatomic or reverse) (TSA), and 90-day post-ARCR hospitalization. MethodsThe PearlDiver Mariner Database was used to collect surgeon-specific variables and query patients who underwent ARCR from 2015 to 2018. Patient outcomes were tracked for two years, including reoperations, hospitalizations, and ICD-10 codes for revision rotator cuff repair (RCR) laterality. Hospitalizations were defined as any emergency department (ED) visit or hospital readmission within 90 days after primary ARCR. Surgeon-specific factors including surgeon case volume, career length, fellowship training, practice setting, and regional practice were analyzed in relation to postoperative outcomes using both univariate and multivariate logistic regression. Results94,150 patients underwent ARCR by 1,489 surgeons. On multivariate analysis, high volume surgeons demonstrated a higher risk for two-year total reoperation (OR = 1.06, 95% CI: 1.01-1.12, P = 0.03) and revision RCR (OR = 1.06, 95% CI: 1.01-1.12, P = 0.02) compared to low volume surgeons. Early-career surgeons showed higher rates of 90-day ED visits (mid-career surgeons: OR = 0.78, 95% CI: 0.73-0.83, P < 0.001; late-career surgeons: OR = 0.73, 95% CI: 0.68-0.78, P < 0.001) and hospital readmission (mid-career surgeons: OR = 0.74, 95% CI: 0.63-0.87, P < 0.001; late-career surgeons: OR = 0.73, 95% CI: 0.61-0.88, P = 0.006) compared to mid- and late-career surgeons. Sports Medicine and/or Shoulder and Elbow fellowship-trained surgeons demonstrated lower two-year reoperation risk (OR = 0.95, CI: 0.91-0.99, P = 0.04) and fewer 90-day ED visits (OR = 0.93, 95% CI = 0.88-0.98, P = 0.002). Academic surgeons experienced higher readmission rates compared to community surgeons (OR = 1.16, 95% CI = 1.01-1.34, P = 0.03). Surgeons practicing in the Northeast demonstrated lower two-year reoperation (OR = 0.88, 95% CI: 0.83-0.93, P < 0.001) and revision (OR = 0.88, 95% CI: 0.83-0.94, P < 0.001) rotator cuff repair risk, compared to surgeons in the Southern United States. ConclusionsHigh-volume surgeons exhibit higher two-year reoperation rates after ARCR compared to low-volume surgeons. Early-career surgeons demonstrate increased hospitalizations. Sports Medicine or Shoulder and Elbow Surgery fellowships correlate with reduced two-year reoperation rates and 90-day ED visits.

Intraoperative Surgeon-Administered Adductor Canal Block Is a Safe Alternative to Preoperative Anesthesiologist-Administered Adductor Canal Block in Primary Total Knee Arthroplasty

BackgroundThe shift toward outpatient total knee arthroplasties (TKAs) has led to a demand for effective perioperative pain control methods. A surgeon-performed “low” adductor canal block (“low-ACB”) technique, involving an intraoperative ACB, is gaining popularity due to its efficiency and early pain control potential. This study examined the transition from traditional preoperative anesthesiologist-performed ultrasound-guided adductor canal blocks (“high-ACB”) to low-ACB, evaluating pain control, morphine consumption, first physical therapy visit gait distance, hospital length-of-stay, and complications. MethodsThere were 2,620 patients at a single institution who underwent a primary total knee arthroplasty between January 1, 2019, and December 31, 2022, and received either a low-ACB or high-ACB. Cohorts included 1,248 patients and 1,372 patients in the low-ACB and high-ACB groups, respectively. Demographics and operative times were similar. Patient characteristics and outcomes such as morphine milligram equivalents (MMEs), Visual Analog Scale pain scores, gait distance (feet), length of stay (days), and postoperative complications (30-day readmission and 30-day emergency department visit) were collected. ResultsThe low-ACB cohort had higher pain scores over the first 24 hours (5.05 versus 4.86, P < .001) and higher MME at 6 hours (11.49 versus 8.99, P < .001), although this was not clinically significant. There was no difference in pain scores or MME at 12 or 24 hours (20.81 versus 22.07 and 44.67 versus 48.78, respectively). The low-ACB cohort showed longer gait distance at the first physical therapy visit (188.5 versus 165.1 feet, P < .001) and a shorter length of stay (0.88 versus 1.46 days, P < .01), but these were not clinically significant. There were no differences in 30-day complications. ConclusionsThe low-ACB offers effective pain relief and comparable early recovery without increasing operative time or the complication rate. Low-ACB is an effective, safe, and economical alternative to high-ACB. Level of EvidenceTherapeutic study, Level III (retrospective cohort study).

Socioeconomic Disparities in Online Patient Portal Utilization Among Total Knee Arthroplasty Recipients

BackgroundSince 2021, the Centers for Medicare and Medicaid Services have mandated that patients have open access to their medical records. Many institutions use online portals, which allow patients to access their health information and communicate with care teams. Our research aimed to evaluate demographic patterns for online patient portal utilization in patients undergoing total knee arthroplasty (TKA). Further, we assessed if and how portal engagement contributes to perioperative outcomes. MethodsThis study retrospectively reviewed primary and elective TKA from 2017 to 2022 at a single academic institution. Patients were stratified into two groups based on their online portal status: activated (A) or not-activated (NA). Baseline characteristics and postoperative outcomes were collected from the electronic medical record and compared. ResultsIn total, 10,995 patients were included: 8,330 (75.8%) were A and 2,625 (24.2%) were NA. The NA group was significantly older (P < 0.001); more likely to be Black (P < 0.001), women (P < 0.001), single/divorced/widowed (P < 0.001), non-English speaking (P < 0.001), and Medicare or Medicaid insured (P < 0.001); from zip codes with median incomes below $50,000 (P < 0.001), and more likely to be American Society of Anesthesiologists (ASA) class III or IV (P < 0.001). Patient-reported outcome measure (PROM) completion rates were significantly lower in the NA group (15.3 versus 47.7%, P < 0.001). Lengths of stay (LOS) were significantly higher in the NA group (2.7 versus 2.1 days, P < 0.001). The NA group was significantly more likely to be discharged to skilled nursing facilities (P < 0.001). Comparable rates of 90-day emergency department visits, readmissions, as well as 90-day and two-year revisions, were observed across groups. ConclusionThere are significant disparities in online portal activation status based on patient demographics. Patients who have activated portals had significantly higher PROM completion rates, shorter LOS, and higher rates of home discharge. Further research should determine which other factors may affect patient portal utilization and inform interventions to improve portal utilization among minority populations.

A Nationwide Analysis of the Impact of Socioeconomic Status on Complications and Health Care Utilizations After Total Knee Arthroplasty Using the Area Deprivation Index: Consideration of the Disadvantaged Patient

BackgroundSocioeconomic status has been demonstrated to be an important prognostic risk factor among patients undergoing total joint arthroplasty. We evaluated patients living near neighborhoods with higher socioeconomic risk undergoing total knee arthroplasty (TKA) and if they were associated with differences in the following: (1) medical complications; (2) emergency department (ED) utilizations; (3) readmissions; and (4) costs of care. MethodsA query of a national database from 2010 to 2020 was performed for primary TKAs. The Area Deprivation Index (ADI) is a weighted index comprised of 17 census-based markers of material deprivation and poverty. Higher numbers indicate a greater disadvantage. Patients undergoing TKA in zip codes associated with high ADI (90%+) were 1:1 propensity-matched to a comparison group by age, sex, and Elixhauser Comorbidity Index. This yielded 225,038 total patients, evenly matched between cohorts. Outcomes studied included complications, ED utilizations, readmission rates, and 90-day costs. Logistic regression models computed the odds ratios (OR) of ADI on the dependent variables. P values less than .003 were significant. ResultsHigh ADI led to higher rates and odds of any medical complications (11.7 versus 11.0%; OR: 1.05, P = .0006), respiratory failures (0.4 versus 0.3%; OR: 1.28, P = .001), and acute kidney injuries (1.7 versus 1.5%; OR: 1.15, P < .0001). Despite lower readmission rates (2.9 versus 3.5%), high ADI patients had greater 90-day ED visits (4.2 versus 4.0%; OR: 1.07, P = .0008). The 90-day expenditures ($15,066 versus $12,459; P < .0001) were higher in patients who have a high ADI. ConclusionsSocioeconomically disadvantaged patients have increased complications and ED utilizations. Neighborhood disadvantage may inform health care policy and improve postdischarge care. The socioeconomic status metrics, including ADI (which captures community effects), should be used to adequately risk-adjust or risk-stratify patients so that access to care for deprived regions and patients is not lost.

Low Household Income Increases Hospital Length of Stay and Decreases Home Discharge Rates in Lumbar Fusion.

Retrospective Matched Cohort Study. Low median household income (MHI) has been correlated with worsened surgical outcomes, but few studies have rigorously controlled for demographic and medical factors at the patient level. This study isolates the relationship between MHI and surgical outcomes in a lumbar fusion cohort using coarsened exact matching. Patients undergoing single-level, posterior lumbar fusion at a single institution were consecutively enrolled and retrospectively analyzed (n = 4263). Zip code was cross-referenced to census data to derive MHI. Univariate regression correlated MHI to outcomes. Patients with low MHI were matched to those with high MHI based on demographic and medical factors. Outcomes evaluated included complications, length of stay, discharge disposition, 30- and 90day readmissions, emergency department (ED) visits, reoperations, and mortality. By univariate analysis, MHI was significantly associated with 30- and 90day readmission, ED visits, reoperation, and non-home discharge, but not mortality. After exact matching (n = 270), low-income patients had higher odds of non-home discharge (OR = 2.5, P = .016) and higher length of stay (mean 100.2 vs 92.6, P = .02). There were no differences in surgical complications, ED visits, readmissions, or reoperations between matched groups. Low MHI was significantly associated with adverse short-term outcomes from lumbar fusion. A matched analysis controlling for confounding variables uncovered longer lengths of stay and higher rates of discharge to post-acute care (vs home) in lower MHI patients. Socioeconomic disparities affect health beyond access to care, worsen surgical outcomes, and impose costs on healthcare systems. Targeted interventions must be implemented to mitigate these disparities.

Addition of vancomycin to cefazolin is often unnecessary for preoperative antibiotic prophylaxis during total joint arthroplasties

PurposeThe gold standard to decrease total joint arthroplasty (TJA) periprosthetic joint infection (PJI) is preoperative antibiotic prophylaxis. Despite substantial prevention efforts, rates of PJIs are increasing. While cefazolin is the drug of choice for preoperative prophylaxis, adjunctive vancomycin therapy has been used in methicillin-resistant Staphylococcus aureus (MRSA) endemic areas. However, studies examining these combinations are lacking. Therefore, we sought to examine complications among vancomycin plus cefazolin and cefazolin-only recipients prior to primary TJA in a single institutional sample and specifically assessed: (1) microbiological aspects, including periprosthetic joint and surgical site infections, microbes cultured from the infection, and frequency of microbes cultured from nasal swab screening; (2) 30-day emergency department (ED) visits and re-admissions; as well as (3) associated risk factors for infection.MethodsA total of 2,907 patients (1,437 receiving both cefazolin and vancomycin and 1,470 given cefazolin only) who underwent primary TJA between 1 January 2014 and 31 May 2021 were identified. SSI and PJI as well as rates of cultured microbes rates were obtained through one year, those with prior nasal swab screening and 30-day re-admission were identified. Subsequently, multiple regression analyses were performed to investigate potential independent risk factors for PJIs.ResultsThere was no significant difference in the rates of SSI (P = 0.089) and PJI (P = 0.279) between the groups at one year after operation. Commonly identified organisms included Staphylococcus and Streptococcus species. The VC cohort did have a greater reduction of MRSA in the previously nasal swab-screened subset of patients. Multiple regression analyses demonstrated emergency as well as inpatient admissions as risk factors for PJI.ConclusionsAdjunctive vancomycin therapy offers increased protection against MRSA in previously screened individuals. However, those negative for MRSA screening do not require vancomycin and have similar protection to infection compared to recipients of cefazolin only in a high-powered single institution analysis in an MRSA endemic area.

Description and Outcomes of a Palliative Care Pharmacist-Led Transitions of Care Program.

Background: Patients with palliative care needs are at high risk of medication errors during transitions of care (TOC). Palliative Care Pharmacist Interventions surrounding Medication Prescribing Across Care Transitions (IMPACT) program was developed to improve the TOC process from hospital to community setting for cancer patients followed by palliative care. We describe (1) the program and (2) pilot study feasibility and effectiveness data. Methods: We recorded pharmacist time, medication errors, drug therapy problems (DTPs), and palliative care provider satisfaction and compared 7- and 30-day readmissions and emergency department (ED) visits between IMPACT and usual care patients. Results: Forty-four patients were reached by the pharmacist. The pharmacist spent an average of 65 minutes per patient. An average of 14.9 medication reconciliation discrepancies per patient and a total 76 DTPs were identified. Seven-day readmissions were lower in the IMPACT group versus usual care; there were no differences in 30-day readmission or 7- or 30-day ED visits. Conclusion: Our pilot study demonstrates that integrating a pharmacist in TOC for seriously ill patients is feasible and valuable.

Elective Joint Replacement Among Medicaid Beneficiaries: Utilization and Postoperative Adverse Events by Racial and Ethnic Groups.

Hip and knee replacement have been marked by racial and ethnic disparities in both utilization and postoperative adverse events among Medicare beneficiaries, but limited knowledge exists regarding racial and ethnic differences in joint replacement care among Medicaid beneficiaries. To close this gap, this study used Medicaid claims in 2018 and described racial and ethnic differences in the utilization and postoperative adverse events of elective joint replacements among Medicaid beneficiaries. Among the 2,260,272 Medicaid beneficiaries, 5987 had an elective joint replacement in 2018. Asian (0.05%, 95% confidence interval [CI]: 0.03%-0.07%) and Hispanic beneficiaries (0.12%, 95% CI: 0.07%-0.18%) received joint replacements less frequently than American Indian and Alaska Native (0.41%, 95% CI: 0.27%-0.55%), Black (0.33%, 95% CI: 0.19%-0.48%), and White (0.37%, 95% CI: 0.25%-0.50%) beneficiaries. Black patients demonstrated the highest probability of 90-day emergency department visits (34.8%, 95% CI: 32.7%-37.0%) among all racial and ethnic groups and a higher probability of 90-day readmission (8.0%, 95% CI: 6.9%-9.0%) than Asian (3.4%, 95% CI: 0.7%-6.0%) and Hispanic patients (4.4%, 95% CI: 3.4%-5.3%). These findings indicate evident disparities in postoperative adverse events across racial and ethnic groups, with Black patients demonstrating the highest probability of 90-day emergency department visits. This study represents an initial exploration of the racial and ethnic differences in joint replacement care among Medicaid beneficiaries and lay the groundwork for further investigation into contributing factors of the observed disparities.

Characterizing changes to older adults' care transition patterns from hospital to home care in the initial year of COVID-19.

Skilled home healthcare (HH) provided in-person care to older adults during the COVID-19 pandemic, yet little is known about the pandemic's impact on HH care transition patterns. We investigated pandemic impact on (1) HH service volume; (2) population characteristics; and (3) care transition patterns for older adults receiving HH services after hospital or skilled nursing facility (SNF) discharge. Retrospective, cohort, comparative study of recently hospitalized older adults (≥ 65 years) receiving HH services after hospital or SNF discharge at two large HH agencies in Baltimore and New York City (NYC) 1-year pre- and 1-year post-pandemic onset. We used the Outcome and Assessment Information Set (OASIS) and service use records to examine HH utilization, patient characteristics, visit timeliness, medication issues, and 30-day emergency department (ED) visit and rehospitalization. Across sites, admissions to HH declined by 23% in the pandemic's first year. Compared to the year prior, older adults receiving HH services during the first year of the pandemic were more likely to be younger, have worse mental, respiratory, and functional status in some areas, and be assessed by HH providers as having higher risk of rehospitalization. Thirty-day rehospitalization rates were lower during the first year of the pandemic. COVID-positive HH patients had lower odds of 30-day ED visit or rehospitalization. At the NYC site, extended duration between discharge and first HH visit was associated with reduced 30-day ED visit or rehospitalization. HH patient characteristics and utilization were distinct in Baltimore versus NYC in the initial year of the COVID-19 pandemic. Study findings suggest some older adults who needed HH may not have received it, since the decrease in HH services occurred as SNF use decreased nationally. Findings demonstrate the importance of understanding HH agency responsiveness during public health emergencies to ensure older adults' access to care.

Female Patients Undergoing Latarjet Surgery Show Similar 2-Year Secondary Surgery Rates but Greater Risk of Emergency Department Visits Compared With a Matched Cohort of Male Patients

To evaluate sex-based differences in 30-day postoperative emergency department (ED) visits, 90-day complication rates, and 2-year secondary surgery rates after the Latarjet procedure for the treatment of recurrent shoulder instability. A national administrative claims database was used to identify patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for shoulder subluxation or dislocation on the day of first-time stabilization with the Latarjet technique between 2015 and 2021. Male patients were matched 4:1 to female patients based on age, Elixhauser Comorbidity Index (ECI) score, and body mass index class. Rates of 30-day ED visits and 90-day complications were compared between cohorts, and risk factors for ED visits were identified by multivariate regression. The incidence of secondary surgery within 2 years was compared by Kaplan-Meier analysis. Prior to matching, 1,059 male and 360 female patients met the inclusion and exclusion criteria. Subsequent 4:1 (male-to-female) matching controlling for age, ECI score, and body mass index yielded 694 male and 185 female patients who underwent the Latarjet procedure. The overall incidence of 30-day ED visits was 9.3%, with an incidence of 8.2% for male patients and 13.5% for female patients. On the basis of multivariate logistic regression, these 30-day ED visits were associated with female sex (odds ratio, 1.79; P= .029) and incrementally higher ECI scores; relative to an ECI score of 0, ECI scores of 1 to 2, 3 to 4, and 5 or greater were associated with odds ratios of 5.31 (P= .006), 8.12 (P < .001), and 12.84 (P < .001), respectively. Ninety-day complications occurred in 1.5% of the total cohort, and the incidence was not statistically different between sexes. Overall, 2-year secondary surgery rates were similar between male and female patients (5.1% and 6.7%, respectively; P= .4). Female patients undergoing the Latarjet procedure for recurrent shoulder instability showed similar 90-day complication and 2-year secondary surgery rates to a matched cohort of male patients. Female sex, along with ECI score, however, was associated with a greater rate of 30-day ED visits. Level III, retrospective comparative case series.

Lack of Association of Pediatric Surgical Patient Outcomes With Increased Disposable Operating Room Supply Costs

IntroductionThere is wide variation in the cost of disposable operating room supplies between surgeons performing the same operation at the same institution. The general relationship between variation in disposable supply cost and patient outcomes is unknown. We aimed to evaluate the relationship between disposable supply cost and patient outcomes for sixteen common operations. MethodsCost data were reviewed for the most common procedures performed by five surgical divisions at a single children's hospital over a six-month period in 2021. For procedure, the median disposable OR costs were calculated. Each operation performed was categorized as low cost (below the group median) or high cost (above the group median. We compared the rates of adverse events (clinic visit within 5 days, 30-day emergency department visit, unplanned reoperation, unplanned readmission, anesthesia complications, prolonged hospital length of stay, need for blood product transfusion, or death) between procedures with low and high disposable supply costs. Results1139 operations performed by 48 unique surgeons from five specialties were included; 596 (52%) were low-cost and 543 (48%) high-cost. The low and high-cost groups did not differ regarding most demographic characteristics. Overall, 21.9% of children suffered any adverse outcome; this rate did not differ between the low and high-cost groups when evaluated individually or in aggregate (20.5% vs 23.6%, p = 0.23). ConclusionOur data demonstrate that across a wide range of pediatric surgical procedures, the cost of disposable operating room supplies was not associated with the risk of adverse outcomes.

Adding Vertebral Bone Quality to the Fusion Risk Score: Does it Improve Predictions of Postoperative Complications?

Retrospective review of prospectively collected data. The current study evaluates whether the addition of the Vertebral Bone Quality (VBQ) score to the Fusion Risk Score (FRS) improves its ability to predict perioperative outcomes. The FRS was developed to assess preoperative risk in patients undergoing thoracic and lumbar fusions. It includes patient-derived and surgical variables, but it does not include one that directly accounts for bone health. The VBQ score allows assessment of bone quality and has been shown to correlate to DEXA-measured bone mineral density (BMD) scores. The VBQ score was weighted based on a regression model and then added to the FRS (FRS/VBQ). The ability of the two scores to predict the outcomes was then assessed using the area under the curve (AUC). Patients undergoing elective thoracic and lumbar spinal fusion from January 2019 to June 2020 were included. The study evaluated various perioperative adverse outcomes, including major and minor adverse events, discharge other than home, extended length of stay, 90-day emergency department visits, 90-day readmission, 90-day and 2-year reoperation rates. 353 met the inclusion and exclusion criteria. The FRS/VBQ demonstrated improved predictive ability compared to the FRS alone when evaluating 90-day reoperation. Both scores showed fair predictive ability for any adverse event, major adverse events, minor adverse events, and 2-year reoperation rates, with AUCs ranging from 0.700 to 0.737. Both had poor predictive ability for the other outcomes. Adding VBQ to the FRS significantly enhances its predictive accuracy for reoperation rate. This updated risk score provides a more comprehensive understanding of a patient's preoperative risk profile, aiding both patients and physicians in assessing surgical risks and optimizing outcomes through preoperative risk stratification.

Association Between Race and Short-Term Outcomes Across 3988 Consecutive Single-Level Spinal Fusions

BACKGROUND AND OBJECTIVES: Race has implications for access to medical care. However, the impact of race, after access to care has been attained, remains poorly understood. The objective of this study was to isolate the relationship between race and short-term outcomes across patients undergoing a single, common neurosurgical procedure. METHODS: In this retrospective cohort study, 3988 consecutive patients undergoing single-level, posterior-only open lumbar fusion at a single, multihospital, academic medical center were enrolled over a 6-year period. Among them, 3406 patients self-identified as White, and 582 patients self-identified as Black. Outcome disparities between all White patients vs all Black patients were estimated using logistic regression. Subsequently, coarsened exact matching controlled for outcome-mitigating factors; White and Black patients were exact-matched 1:1 on key demographic and health characteristics (matched n = 1018). Primary outcomes included 30-day and 90-day hospital readmissions, emergency department (ED) visits, reoperations, mortality, discharge disposition, and intraoperative complication. RESULTS: Before matching, Black patients experienced increased rate of nonhome discharge, readmissions, ED visits, and reoperations (all P &lt; .001). After exact matching, Black patients were less likely to be discharged to home (odds ratio [OR] 2.68, P &lt; .001) and had higher risk of 30-day and 90-day readmissions (OR 2.24, P &lt; .001; OR 1.91, P &lt; .001; respectively) and ED visits (OR 1.79, P = .017; OR 2.09, P &lt; .001). Black patients did not experience greater risk of intraoperative complication (unintentional durotomy). CONCLUSION: Between otherwise homogenous spinal fusion cohorts, Black patients experienced unfavorable short-term outcomes. These disparities were not explained by differences in intraoperative complications. Further investigation must characterize and mitigate institutional and societal factors that contribute to outcome disparities.

The Effect of Marijuana on Postoperative Spine Patients' Emergency Department Visits, Readmission Rates, and Opioid Consumption.

To compare postoperative opioid consumption with patients who tested negative for tetrahydrocannabinol (THC) preoperatively with those who were THC-positive and patients who were positive for THC and any other drug and to compare 90-day rates of postoperative emergency department (ED) visits and 90-day readmission rates, using morphine milligram equivalents (MMEs), for those three patient populations. Three patient groups were confirmed with preoperative urine drug screens. Chart reviews were conducted to determine whether there was an ED visit or hospital readmission 90 days from the index procedure. MMEs were calculated for all patients. There were a total of 252 patients in the THC-negative control group, 54 in the THC-positive group, and 47 in the THC-and-opioid-positive group. The 90-day ED visit and 90-day readmission rates were not statistically significant among the groups. Both the multidrug and THC-only-positive patients showed a higher 90-day MME compared with the control patients. Our study demonstrates that THC used may increase opioid consumption. The THC patients to be cautious toward are the multidrug user. Although not statistically significant, multidrug patients were noted for a trend toward increased ED visits and readmissions.

Evaluation of pharmacist-led transition of care program in patients with acute coronary syndrome

BackgroundGuideline-directed medical therapies (GDMTs), initiated in-hospital and continued during the transition to outpatient care, are paramount to successful outcomes for patients with acute coronary syndrome (ACS). Incomplete discharge medication prescribing and delayed follow-up lead to worse cardiovascular outcomes. ObjectivesWe investigated a system of care using inpatient and outpatient clinical pharmacists to close GDMT gaps, ensure seamless transition to outpatient care, improve patient education, and optimize therapies. MethodsWe conducted a pre-post cohort analysis of patients with ACS pre- versus post-intervention to compare process metrics and key outcomes using electronic health record data. ResultsThere were 181 and 135 patients in the pre- and post-intervention cohorts, respectively. Patients post-intervention were significantly more likely to have appropriately-timed follow-up visits scheduled with cardiology (79% vs. 51%, P < 0.0001) and primary care (57% vs. 43%, P = 0.01), to be discharged with prescriptions for P2Y12 inhibitors (87% vs. 64%, P < 0.0001), high dose statins (86% vs. 70%, P = 0.001), and beta blockers (87% vs. 76%, P = 0.01), and significantly less likely to have 30-day all-cause hospital readmissions (4% vs. 12%, P = 0.02) and emergency department (ED) visits (10% vs. 18%, P = 0.04). ConclusionsThe integration of advanced practicing pharmacists into a cardiology team at transition and post-hospitalization resulted in improved rates of posthospital follow-up visits, optimization of GDMT medications, and significantly lower 30-day hospital readmission and ED utilization.
