Clinical Outcomes of Orthopedic Surgery Co-Management by Internal Medicine Advanced Practice Clinicians: A Cohort Study.

BACKGROUND: Comanagement of orthopedic surgery patients by internal medicine hospitalists is associated with improvements in clinical outcomes including complications, length of stay, and cost. Clinical outcomes of orthopedic comanagement performed solely by internal medicine advanced practice clinicians have not been reported. Our objecyive was to compare clinical outcomes between advanced practice clinician-based comanagement and usual orthopedic care. METHODS: This is a retrospective cohort study in patients 18 years or older, hospitalized for orthopedic joint or spine surgery between May 1, 2014 and January 1, 2022. Outcomes assessed were length of stay, intensive care unit (ICU) transfer, return to operating room, in-hospital and 30-day mortality, 30-day readmission, and total direct cost, excluding surgical implants. Generalized boosted regression and propensity score weighting was used to compare clinical outcomes and health care cost between usual care and advanced practice clinician comanagement. RESULTS: Advanced practice clinician comanagement was associated with a 5% reduction in mean length of stay (rate ratio = 0.95, P = .009), decreased odds of returning to the operating room (odds ratio [OR] 0.51, P = .002), and a significant reduction in 30-day mortality (OR 0.32, P = .037) compared with usual orthopedic care in a weighted analysis. Need for ICU transfer was higher with advanced practice clinician comanagement (OR 1.54, P = .009), without significant differences in 30-day readmission or in-hospital mortality. CONCLUSIONS: We observed reductions in length of stay, health care costs, return to the operating room, and 30-day mortality with advanced practice clinician comanagement compared with usual orthopedic care. Our findings suggest that advanced practice clinician-based comanagement may represent a safe and cost-effective model for orthopedic comanagement.

Clinical outcomes and costs associated with procalcitonin utilization in hospitalized patients with pneumonia, heart failure, viral respiratory infection, or chronic obstructive pulmonary disease.

Lower respiratory tract infections (LRTIs) due to bacterial pneumonia are common among hospitalized patients and are frequently treated with antibiotics. Viral illnesses and exacerbations of heart failure or COPD may present with symptoms mimicking a LRTI, resulting in unnecessary antibiotic utilization. Procalcitonin testing may be useful in these clinical scenarios. We attempted to assess the utility of procalcitonin testing versus not testing, and positive versus negative results among hospitalized patients with suspected LRTI. We performed a retrospective cohort study using multivariable analysis comparing clinical outcomes of patients with and without procalcitonin testing. Patients were 18 years or older, hospitalized for pneumonia, heart failure, COPD, or a viral respiratory illness between October 2014 and October 2015 (n = 2353). All patients received at least one dose of antibiotics. Major outcomes were duration of antibiotic therapy, length of hospital stay, C. difficile testing and infections, and normalized total direct costs. Procalcitonin testing occurred in 14.0% of patients and pneumonia (70.6%) was the most common diagnosis. After covariate adjustments, mean length of stay (5.61 vs. 6.67 days, p < 0.001) and duration of antibiotics (3.95 vs. 4.47 days, p < 0.001) were shorter among tested patients. Fewer 30-day readmissions (OR 0.62, 95% CI 0.40-0.95) were observed, and total direct healthcare costs were 34% lower (0.66, 95% CI 0.58-0.74) among tested patients. Negative procalcitonin results were associated with further reductions in some outcomes. In conclusion, procalcitonin testing among hospitalized patients with suspected LRTI is associated with reductions in antibiotic duration, length of stay, 30-day readmission, and healthcare costs.

Comparison of Resident, Advanced Practice Clinician, and Hospitalist Teams in an Academic Medical Center: Association With Clinical Outcomes and Resource Utilization.

BACKGROUND: Academic medical centers have expanded their inpatient medicine services with advanced practice clinicians (APCs) or nonteaching hospitalists in response to patient volumes, residency work hour restrictions, and recently, COVID-19. Reports of clinical outcomes, cost, and resource utilization differ among inpatient team structures. OBJECTIVE: Directly compare outcomes among resident, APC, and solo hospitalist inpatient general medicine teams. DESIGN: Retrospective cohort study using multivariable analysis adjusted for time of admission, interhospital transfer, and comorbidities that compares clinical outcomes, cost, and resource utilization. SUBJECTS: Patients 18 years or older discharged from an inpatient medicine service between July 2015 and July 2018 (N = 12,716). MAIN MEASURES: Length of stay (LOS), 30-day readmission, inpatient mortality, normalized total direct cost, discharge time, and consultation utilization. KEY RESULTS: Resident teams admitted fewer patients at night (32.0%; P < .001) than did APC (49.5%) and hospitalist (48.6%) teams. APCs received nearly 4% more outside transfer patients (P = .015). Hospitalists discharged patients 26 minutes earlier than did residents (mean hours after midnight [95% CI], 14.58 [14.44-14.72] vs 15.02 [14.97-15.08]). Adjusted consult utilization was 15% higher for APCs (adjusted mean consults per admission [95% CI], 1.00 [0.96-1.03]) and 8% higher for residents (0.93 [0.90-0.95]) than it was for hospitalists (0.85 [0.80-0.90]). No differences in LOS, readmission, mortality, or cost were observed between the teams. CONCLUSION: We observed similar costs, LOS, 30-day readmission, and mortality among hospitalist, APC, and resident teams. Our results suggest clinical outcomes are not significantly affected by team structure. The addition of APC or hospitalist teams represent safe and effective alternatives to traditional inpatient resident teams.

Impact of Hospitalist Team Structure on Patient-Reported Satisfaction with Physician Performance.

BACKGROUND: Patient experience is valuable because it reflects how patients perceive the care they receive within the healthcare system and is associated with clinical outcomes. Also, as part of the Hospital Value-Based Purchasing (HVBP) program, the Center for Medicare and Medicaid Services (CMS) rewards hospitals with financial incentives for patient experience as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. It is unclear how the addition of residents and advanced practice clinicians (APCs) to hospitalist-led inpatient teams affects patient satisfaction as measured by the HCAHPS and Press Ganey survey. OBJECTIVE: To compare patient satisfaction with hospitalists on resident, APC, and solo hospitalist teams measured by HCAHPS and Press Ganey physician performance domain survey results. DESIGN: Retrospective observational cohort study. PARTICIPANTS: All patients discharged from the Internal Medicine inpatient service between July 1, 2015, and July 1, 2018, who met HCAHPS survey eligibility criteria and completed a patient experience survey. MAIN MEASURES: HCAHPS and Press Ganey physician performance domain survey results. KEY RESULTS: No differences were observed in the selection of "top box" scores on the HCAHPS physician performance domain between resident, APC, and solo hospitalist teams. Adjusted Press Ganey physician performance domain survey results demonstrated significant differences between solo hospitalist and resident teams, with solo hospitalists having higher scores in three areas: time physician spent with you (4.58 vs. 4.38, p = 0.050); physician kept you informed (4.63 vs. 4.43, p = 0.047); and physician skill (4.80 vs. 4.63, p = 0.027). Solo hospitalists were perceived to have higher physician skill in comparison with hospitalist-APC teams (4.80 vs. 4.69, p = 0.042). CONCLUSION: While Press Ganey survey results suggest that patients have greater satisfaction with physicians on solo hospitalist teams, these differences were not observed on the HCAHPS physician performance survey domain, suggesting physician team structure does not impact HVBP incentive payments by CMS.

The association of inpatient blood utilization and diagnosis-related group weight: implications for risk-adjusted benchmarking.

BACKGROUND: Risk-adjusted benchmarking could be useful to compare blood utilization between hospitals or individual groups, such as physicians, while accounting for differences in patient complexity. The aim of this study was to analyze the association of red blood cell (RBC) use and diagnosis-related group (DRG) weights across all inpatient hospital stays to determine the suitability of using DRGs for between-hospital risk-adjusted benchmarking. Specific hierarchical organizational units (surgical vs. nonsurgical patients, departments, and physicians) were also evaluated. STUDY DESIGN AND METHODS: We studied blood use among all adult inpatients, and within organizational units, over 4 years (May 2014 to March 2018) at an academic center. Number of RBCs transfused, all patient refined (APR)-DRGs, and other variables were captured over entire hospital stays. We used multilevel generalized linear modeling (zero-inflated negative binomial) to study the relationship between RBC utilization and APR-DRG. RESULTS: A total of 97,955 hospital stays were evaluated and the median APR-DRG weight was 1.2. The association of RBCs transfused and APR-DRG weight was statistically significant at all hierarchical levels (incidence rate ratio = 1.22; p < 0.001). The impact of APR-DRG on blood use, measured by the incidence rate ratio, demonstrated an association at the all-patient and surgical levels, at several department and physician levels, but not at the medical patient level. The relationship between RBCs transfused and APR-DRG varied across organizational units. CONCLUSION: Number of RBCs transfused was associated with APR-DRG weight at multiple hierarchical levels and could be used for risk-adjusted benchmarking in those contexts. The relationship between RBC use and APR-DRG varied across organizational units.

Screening for novel risk factors related to peripherally inserted central catheter-associated complications.

BACKGROUND: Peripherally inserted central catheters (PICCs) are increasingly utilized. Patient and system factors that increase risk of complications should be identified to avoid preventable patient harm. METHODS: A case control analysis of adult inpatients who underwent PICC placement from January 2009 to January 2010 at Scott & White Memorial Hospital was conducted to determine the incidence and risk factors for complications. One hundred seventy cases of inpatients who experienced PICC-related complications were identified. Age- and gender-matched controls were randomly selected among patients who underwent PICC placement without documented complications during this time. RESULTS: A total of 1444 PICCs were placed, with a complication rate of 11.77% (95% confidence interval: 10.11%-13.44%). Complications included catheter-associated thrombosis (3%), mechanical complications (4%), catheter-associated bloodstream infections (2%), and cellulitis (1%). In multivariable logistic regression analyses, malnutrition and after-hours placement were significantly associated with increased risk of complications, as was body mass index (BMI) >30 after adjusting for anticoagulation and time of placement. In a secondary multivariable logistic regression analysis, after-hours placement and malnutrition were significantly associated with increased risk of nonmechanical complications. Additionally, in conditional univariate analyses, length of stay, malnutrition, and after-hours placement were associated with increased risk of catheter-associated thrombosis. In our multivariable logistic regression analyses, use of anticoagulation/antiplatelet agents was associated with decreased risk of all-cause complications, nonmechanical complications, and catheter-associated thrombosis. CONCLUSIONS: Screening of patients undergoing PICC placement with attention to malnutrition, BMI >30, and length of stay may reduce the risk of PICC-associated complications. Use of anticoagulation/antiplatelet agents and avoiding after-hours placement may reduce complications and enhance patient safety.

Residents examine factors associated with 30-day, same-cause hospital readmissions on an internal medicine service.

In recent years, there has been increased interest in stemming the tide of hospital readmissions in an attempt to improve quality of care. This study presents the Phase I results of a resident-led quality improvement initiative to determine the percentage of and risk factors for same-cause readmissions (SCRs; defined as hospital readmission within 30 days of hospital discharge for treatment of the same condition) to the internal medicine service of a multispecialty teaching hospital in central Texas. Results indicate that patients diagnosed with chronic obstructive pulmonary disease/asthma or anemia may be at increased risk for SCRs. Those patients who are insured by Medicaid and those who require assistance from social services also demonstrated an increased risk for SCRs. This study appears to be the first resident-led initiative in the field to examine 30-day SCRs to an internal medicine service for demographic and clinical risk factors.

Blockade of invasion and metastasis of breast cancer cells via targeting CXCR4 with an artificial microRNA.

miRNAs have been shown to function as regulatory molecules and to play an important role in cancer progression. Very little is currently known about the increasing invasion and metastasis of breast cancer due to the loss of expressive levels of certain miRNAs in breast tumor cells. In order to determine whether the CXCR4/SDF-1 pathway is regulated by expression of miRNAs, we designed and synthesized pre-miRNA against CXCR4. This double-stranded miRNA gene was ligated with a miR-155-based Block-iT Pol II miR RNAi Expression Vector (Invitrogen). Expression levels of CXCR4 in CXCR4-miRNA-transfected breast tumor cells had significantly declined. These cells exhibited reduced migration and invasion in vitro. Furthermore, they formed fewer lung metastases in vivo compared to ctrl-miRNA-transfected cells. These data support the conclusion that miRNA against CXCR4 can serve as an alterative means of therapy to lower CXCR4 expression and to block the invasion and metastasis of breast cancer cells.

Current approaches to the diagnosis and treatment of cholangiocarcinoma.

Malignancies arising from biliary tract epithelia, or cholangiocarcinoma, are rare tumors that have a poor prognosis. The incidence of these tumors is gradually increasing in many countries. Recent advances have been made in identifying some of the risk factors, and the need for appropriate classification is emerging. The diagnosis of cholangiocarcinoma is often difficult and requires multiple complementary studies. The use of molecular approaches may improve the diagnostic utility of biliary cytology. Treatment of these tumors is complex, and there are many different treatment options. Although surgical resection can be curative, many patients with cholangiocarcinoma are diagnosed at an advanced stage when only palliative approaches can be used. Photodynamic therapy is emerging as a useful modality.
