Impact of the Comprehensive Care for Joint Replacement Bundled Payment Model on Postoperative Utilization of Home Health and Outpatient Physical Therapy Services.

OBJECTIVE: To study the effect of the Comprehensive Care for Joint Replacement (CJR) bundled payment program on postoperative home health and outpatient physical therapy (PT) for total hip or knee arthroplasty (THA/TKA). DESIGN: Retrospective cohort with national Medicare data (5% claims) using a difference-in-differences analysis comparing January 2013-September 2015 (before) versus October 2016-September 2019 (after). SETTING: Administrative claims from hospitals in 34 metropolitan statistical areas with mandatory CJR participation as of 2018 and 42 control metropolitan statistical areas. PARTICIPANTS: Episodes in fee-for-service Medicare beneficiaries (5% claims) undergoing elective THA (n=6327) or TKA (n=10,764) with community discharge. INTERVENTIONS: Implementation of CJR bundled payment program. MAIN OUTCOME MEASURES: Home health and outpatient PT, including any use and number of visits. RESULTS: Program implementation was associated with an increased percentage of THA episodes using home health PT (+8.0 percentage-point change; 95% CI, +3.5 to +12.6; P=.001) but a decreased per-episode number of home health PT visits for THA (-1.1; 95% CI, -1.6 to -0.6; P<.001) and TKA (-1.1; 95% CI, -1.4 to -0.7; P<.001). The program was also associated with an increased per-episode number of outpatient PT visits for TKA in the primary but not sensitivity analyses (+0.8; 95% CI, +0.1 to +1.4; P=.02). CONCLUSIONS: Findings of increased home health PT may reflect an intentional shift in care from the inpatient postacute setting to the community to decrease costs. Alternatively, the limited effect of CJR, particularly on outpatient PT, could reflect challenges with care coordination in a retrospective bundle spanning multiple care settings.

A Remote Consult Retinal Artery Occlusion Diagnostic Protocol.

PURPOSE: To report a novel protocol for diagnosis of retinal artery occlusions at the point of care using OCT and a remote consult model. DESIGN: Retrospective case series and evaluation of a diagnostic test or technology. PARTICIPANTS: Adult patients who presented with painless monocular vision loss and were diagnosed with a nonarteritic retinal artery occlusion. METHODS: OCT machines were placed in the stroke center or emergency department at 3 hospitals within our health system. Patients who presented with painless monocular vision loss were evaluated by the stroke neurology service and an OCT was acquired. The images were interpreted remotely by the retina service. An in-house ophthalmology consult was not required to make the final treatment decision. Eligible patients were treated with intra-arterial tissue plasminogen activator (IA-tPA). Patients were followed by ophthalmology during their admission when an in-house consultation service was available or otherwise evaluated immediately after discharge. MAIN OUTCOME MEASURES: Visual acuity (VA) before and after treatment with IA-tPA; time from last known well (LKW) to treatment; and time from presentation to treatment. RESULTS: In the first 18 months since the protocol went live, 59 patients were evaluated. Twenty-five patients (42%) had a confirmed retinal artery occlusion based on OCT and follow-up examination. Ten patients were eligible for treatment, and 9 patients received treatment with IA-tPA. There was a statistically significant improvement in mean VA from logarithm of the minimum angle of resolution (logMAR) 2.14 to logMAR 0.7 within 24 hours after treatment (P = 0.0001) and logMAR 1.04 after 4 weeks (P = 0.01). Clinically significant improvement was noted in 66% of patients within 24 hours and maintained through 1 month in 56% of all treated patients. The mean time to treatment from LKW was 543 minutes and from presentation at the stroke center was 146 minutes. CONCLUSIONS: We report the successful implementation of a remote consult protocol using point-of-care automated OCT. This novel paradigm demonstrates the potential utility of remote consult services for the diagnosis of time-sensitive ophthalmic emergencies.

Cardiac coronary tomography angiography (CCTA) use across geographical regions in the USA and the UK: a cross-sectional study.

Objective: Increased use of CT imaging has been identified as a key component of unsustainable rising healthcare costs in the USA and globally. Understanding evidence and its relation to imaging coverage policies can help identify patterns of variation to better inform high value care initiatives. This cross-sectional study evaluates regional differences in US utilisation of cardiac coronary tomography angiography (CCTA) and compares use in the USA and England. Design: We determined differences in CCTA order rates by US Medicare region and compared order rates in the US and England, compared CT scanner prevalence in the USA and UK, and reviewed the CCTA coverage policies for each region. Setting: The US and the UK. Participants: Medicare Coverage Database; Medicare 2018 Part B data; National Health Services 2018 data. Interventions: CCTA orders, CT scanner prevalence. Main outcome measures: CCTA orders per beneficiary, CT scanner prevalence, CCTA policy variation. Results: We found that CCTA coverage policies are more permissive in the UK compared with the USA. However, CT scanner prevalence per beneficiary is four times greater in the USA than the UK. There was significant variation in number of CCTA ordered per 100 000 beneficiaries between regions in England and the USA, ranging from 74 to 313 in the US and 57-317 in England. Conclusions: There is significant geographical variation in use of CCTA in both the USA and England, although overall use does not differ significantly between both countries. Similarities in order rates, despite a much higher CT scanner density in the USA, may be related to more permissive guidelines around use of CCTA in the UK. Variation in both countries may also reflect the lack of high-quality clinical outcomes data for use of CCTA, underscoring opportunities for more evidence and evidence-based policy to promote appropriate use of CCTA imaging.

High Myopia Prevalence across Racial Groups in the United States: A Systematic Scoping Review.

High myopia is a significant public health issue globally and in the United States (US), where it affects ~4% of the population or 13 million people. This is a potentially blinding condition, but complications can be prevented with early intervention in childhood. Several countries have developed robust data on high myopia, but the United States' data on high myopia remains lacking. Further, underrepresented populations are at particular risk of complications due to reduced access to optometric and ophthalmic care. We performed a systematic scoping review of population-based studies that investigated the prevalence of high myopia across racial and ethnic groups in the US to identify the impact of high myopia on underrepresented communities. Only four studies were identified that met inclusion criteria, which highlights the need to further investigate the topic in the United States. The prevalence of high myopia ranged from a low of 1.8% among Hispanic populations to a high of 11.8% among Chinese populations. Our study demonstrated a paucity of high myopia data in the United States and variable rates of high myopia depending on the time and location of each study. More complete prevalence data will help identify opportunities for community-based interventions to prevent debilitating and blinding complications of high myopia.

An interdisciplinary student-led multifaceted intervention addressing overuse of broad-spectrum antibiotics for patients with penicillin allergies.

BACKGROUND: Though 15% of hospitalized patients have a documented penicillin (PCN) allergy, fewer than 1% have an IgE-mediated reaction that necessitates avoidance of ß-lactam antibiotics. OBJECTIVE: Our interdisciplinary team of medical and nursing students led and executed a two-pronged quality improvement intervention to reduce prescribing of non-ß-lactam antibiotics (NBLs) for patients with reported PCN allergies. To the best of our knowledge, this is the first multidisciplinary student-led intervention aimed at educating providers on low-risk penicillin allergy and encouraging best antibiotic prescribing practices. DESIGN AND PARTICIPANTS: The intervention took place from June 2021 to February 2022. We developed and provided clinician education modules, including peer-to-peer information sharing and in-person small group discussions, as well as clinical decision support (CDS) strategies through the electronic medical record (EMR). The target population was attendings, residents, nurse practitioners, and physician assistants on the hospital medicine service at a large urban academic tertiary care center. We followed the SQUIRE 2.0 guidelines for reporting on quality improvement. MAIN MEASURES: Primary outcome measures included number of NBL prescriptions and use of nonspecific descriptors (e.g., "other" or "unknown") for PCN allergy reaction type, and were compared with a pre-intervention period. KEY RESULTS: The percent of ß-lactam prescriptions for patients with a PCN allergy after the intervention increased from 19 to 23% (p = 0.006). For patients with a low severity PCN allergy, the percent of ß-lactam prescriptions increased from 20 to 28% (p = 0.001). There was a significant decrease in nonspecific PCN allergy reaction type from 23% in the pre-intervention period to 20% post-intervention (p = 0.012). CONCLUSIONS: An intervention focused on educating prescribers and CDS strategies delivered through the EMR increased appropriate ß-lactam prescribing for patients with a documented low-risk PCN allergy and reduced the use of nonspecific PCN allergy reaction type in EMR documentation.

Performance of the academic research consortium high-bleeding risk criteria in patients undergoing PCI for acute myocardial infarction.

Patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) are at increased risk for thrombotic and bleeding complications compared to patients with chronic coronary syndrome (CCS). The academic research consortium (ARC) recently suggested a set of criteria to identify patients at high bleeding risk (HBR). We sought to evaluate the performance of the ARC-HBR criteria among patients undergoing PCI according to clinical presentation. We included all consecutive patients undergoing PCI at a tertiary-care center. Patients were deemed at HBR if they fulfilled ≥ 1 major or ≥ 2 minor ARC-HBR criteria. The primary bleeding endpoint was a composite of in-hospital or post-discharge bleeding at 1-year follow-up. Secondary outcomes included all-cause death and myocardial infarction. Out of 6068 patients, 1391 (22.9 %) presented with AMI and were more often at HBR than those with CCS (46.9 % vs. 43.0 %, p = 0.01). HBR patients had a higher risk for the primary bleeding endpoint than non-HBR, irrespective of the clinical indication for PCI (AMI: 19.5 % vs. 5.5 %; HR 3.86, 95 % CI 2.63-5.69; CCS: 6.8 % vs. 2.6 %; HR 2.65, 95 % CI 1.92-3.68; p-interaction = 0.11). Secondary outcomes followed a similar trend. After multivariable adjustment, AMI presentation remained significantly associated with increased risk for bleeding at 1 year (HR 1.64, 95 % CI 1.13-2.38, p = 0.01). The ARC-HBR criterion associated with the highest bleeding risk was severe/end-stage chronic kidney disease in AMI and moderate/severe anemia in CCS. The ARC-HBR framework successfully identified AMI and CCS patients with increased risk for bleeding complications at 1 year post-PCI. Figure prepared with BioRender.

Frequency of Eating Disorder Pathology Among Patients With Chronic Constipation and Contribution of Gastrointestinal-Specific Anxiety.

BACKGROUND & AIMS: Individuals with eating disorders (EDs) frequently have constipation-related symptoms, although the mechanisms of this relationship are not clear. We examined the frequency of and relation between EDs and constipation in patients with chronic constipation referred for anorectal manometry. METHODS: We analyzed data from 279 patients with chronic constipation (79.2% female) evaluated at a tertiary center from June 2017 through September 2018. Participants completed a standardized psychometric assessment (patient assessment of constipation symptoms questionnaire and hospital anxiety and depression scale and visceral sensitivity index analyses) and anorectal manometry. A subset of patients completed colonic transit testing. Participants with clinically significant ED pathology were identified based on scores of 20 or higher on the Eating Attitudes Test-26. We performed a logistic regression analysis to examine factors associated with the likelihood of having ED pathology. Odds ratios were calculated based on continuous variables. We examined the contribution of anxiety to the relationship between severity of ED pathology and symptoms of constipation (such as abdominal pain) using a regression-based bootstrapping approach. RESULTS: Of the study participants, 53 (19.0%) had clinically significant ED pathology. The presence of ED pathology was associated with greater general anxiety scores, based on the hospital anxiety and depression scale (odds ratio, 1.20; 95% CI, 1.05-1.38), and greater gastrointestinal-specific anxiety scores, based on the visceral sensitivity index (odds ratio, 1.06; 95% CI, 1.03-1.09). Gastrointestinal-specific anxiety fully mediated the relationship between the severity of ED pathology and constipation (standardized ß, 0.11-0.16; P = .026-.024). We found no differences in anorectal manometry or colonic transit between patients with vs without ED pathology. CONCLUSIONS: In an analysis of patients with chronic constipation, we found that 19% had clinically significant ED pathology. Our preliminary finding indicated that ED pathology might contribute to constipation via gastrointestinal-specific anxiety. Clinicians should consider screening patients with chronic constipation for EDs-especially patients who report symptoms such as bloating and abdominal pain.
