RESUMEN
OBJECTIVES: The 2021 US Cures Act may engage patients to help reduce diagnostic errors/delays. We examined the relationship between patient portal registration with/without note reading and test/referral completion in primary care. MATERIALS AND METHODS: Retrospective cohort study of patients with visits from January 1, 2018 to December 31, 2021, and order for (1) colonoscopy, (2) dermatology referral for concerning lesions, or (3) cardiac stress test at 2 academic primary care clinics. We examined differences in timely completion ("loop closure") of tests/referrals for (1) patients who used the portal and read ≥1 note (Portal + Notes); (2) those with a portal account but who did not read notes (Portal Account Only); and (3) those who did not register for the portal (No Portal). We estimated the predictive probability of loop closure in each group after adjusting for socio-demographic and clinical factors using multivariable logistic regression. RESULTS: Among 12 849 tests/referrals, loop closure was more common among Portal+Note-readers compared to their counterparts for all tests/referrals (54.2% No Portal, 57.4% Portal Account Only, 61.6% Portal+Notes, P < .001). In adjusted analysis, compared to the No Portal group, the odds of loop closure were significantly higher for Portal Account Only (OR 1.2; 95% CI, 1.1-1.4), and Portal+Notes (OR 1.4; 95% CI, 1.3-1.6) groups. Beyond portal registration, note reading was independently associated with loop closure (P = .002). DISCUSSION AND CONCLUSION: Compared to no portal registration, the odds of loop closure were 20% higher in tests/referrals for patients with a portal account, and 40% higher in tests/referrals for note readers, after controlling for sociodemographic and clinical factors. However, important safety gaps from unclosed loops remain, requiring additional engagement strategies.

BACKGROUND: A frequent, preventable cause of diagnostic errors involves failure to follow up on diagnostic tests, referrals, and symptoms-termed "failure to close the diagnostic loop." This is particularly challenging in a resident practice where one third of physicians graduate annually, and rates of patient loss due to these transitions may lead to more opportunities for failure to close diagnostic loops. The aim of this study was to determine the prevalence of failure of loop closure in a resident primary care clinic compared to rates in the faculty practice and identify factors contributing to failure. METHODS: This retrospective cohort study included all patient visits from January 1, 2018, to December 31, 2021, at two academic medical center-based primary care practices where residents and faculty practice in the same setting. The primary outcome was prevalence of failure to close the loop for (1) dermatology referrals, (2) colonoscopy, and (3) cardiac stress testing. The primary predictor was resident vs. faculty status of the ordering provider. The authors present an unadjusted analysis and the results of a multivariable logistic regression analysis incorporating all patient factors to determine their association with loop closure. RESULTS: Of 12,282 orders for referrals and tests for the three studied areas, 1,929 (15.7%) were ordered by a resident physician. Of resident orders for all three tests, 52.9% were completed within the designated time vs. 58.4% for orders placed by attending physicians (p < 0.01). In an unadjusted analysis by test type, a similar trend was seen for colonoscopy (51.4% completion rate for residents vs. 57.5% for attending physicians, p < 0.01) and for cardiac stress testing (55.7% completion rate for residents vs. 61.2% for attending physicians), though a difference was not seen for dermatology referrals (64.2% completion rate for residents vs. 63.7% for attending physicians). In an adjusted analysis, patients with resident orders were less likely than attendings to close the loop for all test types combined (odds ratio 0.88, 95% confidence interval 0.79-0.98), with low rates of test completion for both physician groups. CONCLUSION: Loop closure for three diagnostic interventions was low for patients in both faculty and resident primary care clinics, with lower loop closure rates in resident clinics. Failure to close diagnostic loops presents a safety challenge in primary care and is of particular concern for training programs.

BACKGROUND: Rectal bleeding is the most common presenting symptom of colorectal cancer, and guidelines recommend timely follow-up, usually with colonoscopy to ensure timely diagnoses of colorectal cancer. OBJECTIVE: Identify loop closure rates and vulnerable process points for patients with rectal bleeding. DESIGN: Retrospective cohort study, using medical record review of patients aged ≥ 40 with index diagnosis of rectal bleeding at 2 primary practices-an urban academic practice and affiliated community health center, between January 1, 2018, and December 31, 2020. Patients were classified as having completed recommended follow-up workup ("closed loop") vs. not ("open loop"). Open loop patient cases were categorized into six types of process failures. PARTICIPANTS: A total of 837 patients had coded diagnoses of rectal bleeding within study window. Sixty-seven were excluded based on prior colectomy, clinical presentation more consistent with upper GI bleed, no rectal bleeding documented on chart review, or expired during the follow-up period, leaving 770 patients included. MAIN MEASURES: Primary outcomes were percentages of patient cases classified as "open loops" and distribution of these cases into six categories of process failure that were identified. KEY RESULTS: 22.3% of patients (N = 172) failed to undergo timely recommended workup for rectal bleeding. Largest failure categories were patients for whom no procedure was ordered (N = 62, 36%), followed by patients with procedures ordered but never scheduled (N = 44, 26%) or scheduled but subsequently cancelled or not kept (N = 31, 18%). While open loops increased after the onset of the COVID-19 pandemic, this difference was not significant within our study period. CONCLUSIONS: Significant numbers of patients presenting to primary care with rectal bleeding fail to undergo recommended workup. The majority either have no procedure ordered, or procedure ordered but never scheduled or cancelled and not kept, suggesting these are important failure modes to target in future interventions. Ensuring reliable ordering and processes for timely scheduling and completion of procedures represent critical areas for improving the diagnostic process for patients with rectal bleeding in primary care.
RESUMEN
Importance: Use of telehealth has increased substantially in recent years. However, little is known about whether the likelihood of completing recommended tests and specialty referrals-termed diagnostic loop closure-is associated with visit modality. Objectives: To examine the prevalence of diagnostic loop closure for tests and referrals ordered at telehealth visits vs in-person visits and identify associated factors. Design, Setting, and Participants: In a retrospective cohort study, all patient visits from March 1, 2020, to December 31, 2021, at 1 large urban hospital-based primary care practice and 1 affiliated community health center in Boston, Massachusetts, were evaluated. Main Measures: Prevalence of diagnostic loop closure for (1) colonoscopy referrals (screening and diagnostic), (2) dermatology referrals for suspicious skin lesions, and (3) cardiac stress tests. Results: The study included test and referral orders for 4133 patients (mean [SD] age, 59.3 [11.7] years; 2163 [52.3%] women; 203 [4.9%] Asian, 1146 [27.7%] Black, 2362 [57.1%] White, and 422 [10.2%] unknown or other race). A total of 1151 of the 4133 orders (27.8%) were placed during a telehealth visit. Of the telehealth orders, 42.6% were completed within the designated time frame vs 58.4% of those ordered during in-person visits and 57.4% of those ordered without a visit. In an adjusted analysis, patients with telehealth visits were less likely to close the loop for all test types compared with those with in-person visits (odds ratio, 0.55; 95% CI, 0.47-0.64). Conclusions: The findings of this study suggest that rates of loop closure were low for all test types across all visit modalities but worse for telehealth. Failure to close diagnostic loops presents a patient safety challenge in primary care that may be of particular concern during telehealth encounters.

While the field of synthetic developmental biology has traditionally focused on the study of the rich developmental processes seen in metazoan systems, an attractive alternate source of inspiration comes from microbial developmental models. Microbes face unique lifestyle challenges when forming emergent multicellular collectives. As a result, the solutions they employ can inspire the design of novel multicellular systems. In this review, we dissect the strategies employed in multicellular development by two model microbial systems: the cellular slime mold Dictyostelium discoideum and the biofilm-forming bacterium Bacillus subtilis. Both microbes face similar challenges but often have different solutions, both from metazoan systems and from each other, to create emergent multicellularity. These challenges include assembling and sustaining a critical mass of participating individuals to support development, regulating entry into development, and assigning cell fates. The mechanisms these microbial systems exploit to robustly coordinate development under a wide range of conditions offer inspiration for a new toolbox of solutions to the synthetic development community. Additionally, recreating these phenomena synthetically offers a pathway to understanding the key principles underlying how these behaviors are coordinated naturally.

Ideally, urgent dermatology referrals for evaluation of a lesion concerning for skin cancer should be triaged and processed with appropriate urgency by primary care and dermatology, respectively. We performed a retrospective single-institution study by conducting chart reviews of all dermatology referrals designated by primary care as urgent for evaluation of a lesion concerning for skin cancer. We identified 320 referrals placed between January 1 and December 31, 2018. Dermatology encounters for these patients occurred on or before 30 days for 50.6% of referrals and on or after 31 days for 38.4% of referrals, with 10.9% never completed. The percentage of all races excluding whites, non-Hispanic in the delayed appointment group (≥ 31 days) was 15.1% higher (95% CI 5.3-24.9) than in the timely appointment group (≤ 30 days). Similarly, the percentage of non-English languages in the delayed group was 7.1% higher (95% CI 0.5-13.7) than in the timely group. Overall, 15.8% of these referrals yielded diagnoses of malignancy, while 76.8% and 7.4% resulted in benign and pre-malignant diagnoses, respectively. The primary care team documented referral status (i.e., completed, incomplete, or pending) during their subsequent visits with the patients in only 37.5% of these referrals. Our findings demonstrate the need to improve the reliability of urgent referrals to ensure they occur in a timely manner with confirmation of "referral loop" closure at the referring clinician's end.

Importance: Following up on recommendations from radiologic findings is important for patient care, but frequently there are failures to carry out these recommendations. The lack of reliable systems to characterize and track completion of actionable radiology report recommendations poses an important patient safety challenge. Objectives: To characterize actionable radiology recommendations and, using this taxonomy, track and understand rates of loop closure for radiology recommendations in a primary care setting. Design, Setting, and Participants: Radiology reports in a primary care clinic at a large academic center were redesigned to include actionable recommendations in a separate dedicated field. Manual review of all reports generated from imaging tests ordered between January 1 and December 31, 2018, by primary care physicians that contained actionable recommendations was performed. For this quality improvement study, a taxonomy system that conceptualized recommendations was developed based on 3 domains: (1) what is recommended (eg, repeat a test or perform a different test, specialty referral), (2) specified time frame in which to perform the recommended action, and (3) contingency language qualifying the recommendation. Using this framework, a 2-stage process was used to review patients' records to classify recommendations and determine loop closure rates and factors associated with failure to complete recommended actions. Data analysis was conducted from April to July 2021. Main Outcomes and Measures: Radiology recommendations, time frames, and contingencies. Rates of carrying out vs not closing the loop on these recommendations in the recommended time frame were assessed. Results: A total of 598 radiology reports were identified with structured recommendations: 462 for additional or future radiologic studies and 196 for nonradiologic actions (119 specialty referrals, 47 invasive procedures, and 43 other actions). The overall rate of completed actions (loop closure) within the recommended time frame was 87.4%, with 31 open loop cases rated by quality expert reviewers to pose substantial clinical risks. Factors associated with successful loop closure included (1) absence of accompanying contingency language, (2) shorter recommended time frames, and (3) evidence of direct radiologist communication with the ordering primary care physicians. A clinically significant lack of loop closure was found in approximately 5% of cases. Conclusions and Relevance: The findings of this study suggest that creating structured radiology reports featuring a dedicated recommendations field permits the development of taxonomy to classify such recommendations and determine whether they were carried out. The lack of loop closure suggests the need for more reliable systems.

BACKGROUND: Closing loops to complete diagnostic referrals remains a significant patient safety problem in most health systems, with 65%-73% failure rates and significant delays common despite years of improvement efforts, suggesting new approaches may be useful. Systems engineering (SE) methods increasingly are advocated in healthcare for their value in studying and redesigning complex processes. OBJECTIVE: Conduct a formative SE analysis of process logic, variation, reliability and failures for completing diagnostic referrals originating in two primary care practices serving different demographics, using dermatology as an illustrating use case. METHODS: An interdisciplinary team of clinicians, systems engineers, quality improvement specialists, and patient representatives collaborated to understand processes of initiating and completing diagnostic referrals. Cross-functional process maps were developed through iterative group interviews with an urban community-based health centre and a teaching practice within a large academic medical centre. Results were used to conduct an engineering process analysis, assess variation within and between practices, and identify common failure modes and potential solutions. RESULTS: Processes to complete diagnostic referrals involve many sub-standard design constructs, with significant workflow variation between and within practices, statistical instability and special cause variation in completion rates and timeliness, and only 21% of all process activities estimated as value-add. Failure modes were similar between the two practices, with most process activities relying on low-reliability concepts (eg, reminders, workarounds, education and verification/inspection). Several opportunities were identified to incorporate higher reliability process constructs (eg, simplification, consolidation, standardisation, forcing functions, automation and opt-outs). CONCLUSION: From a systems science perspective, diagnostic referral processes perform poorly in part because their fundamental designs are fraught with low-reliability characteristics and mental models, including formalised workaround and rework activities, suggesting a need for different approaches versus incremental improvement of existing processes. SE perspectives and methods offer new ways of thinking about patient safety problems, failures and potential solutions.

COVID-19 necessitated significant care redesign, including new ambulatory workflows to handle surge volumes, protect patients and staff, and ensure timely reliable care. Opportunities also exist to harvest lessons from workflow innovations to benefit routine care. We describe a dedicated COVID-19 ambulatory unit for closing testing and follow-up loops characterized by standardized workflows and electronic communication, documentation, and order placement. More than 85% of follow-ups were completed within 24 hours, with no observed staff, nor patient infections associated with unit operations. Identified issues include role confusion, staffing and gatekeeping bottlenecks, and patient reluctance to visit in person or discuss concerns with phone screeners.

Interactions between the actin cytoskeleton and the plasma membrane are important in many eukaryotic cellular processes. During these processes, actin structures deform the cell membrane outward by applying forces parallel to the fiber's major axis (as in migration) or they deform the membrane inward by applying forces perpendicular to the fiber's major axis (as in the contractile ring during cytokinesis). Here we describe a novel actin-membrane interaction in human dermal myofibroblasts. When labeled with a cytosolic fluorophore, the myofibroblasts displayed prominent fluorescent structures on the ventral side of the cell. These structures are present in the cell membrane and colocalize with ventral actin stress fibers, suggesting that the stress fibers bend the membrane to form a "cytosolic pocket" that the fluorophores diffuse into, creating the observed structures. The existence of this pocket was confirmed by transmission electron microscopy. While dissolving the stress fibers, inhibiting fiber protein binding, or inhibiting myosin II binding of actin removed the observed pockets, modulating cellular contractility did not remove them. Taken together, our results illustrate a novel actin-membrane bending topology where the membrane is deformed outward rather than being pinched inward, resembling the topological inverse of the contractile ring found in cytokinesis.

Background: Nondiagnostic results are common following fine-needle aspiration biopsy (FNAB) of thyroid nodules, but recommendations for the management of these patients vary. We sought to determine the outcomes and predictors of nondiagnostic FNABs in a single-center cohort of patients undergoing thyroid nodule evaluation. Methodology: We identified all first time ultrasound-guided FNABs performed between May 2007 and June 2013 at the Beth Israel Deaconess Medical Center Thyroid Nodule Clinic and examined demographic data, follow-up ultrasounds, repeated FNABs, and histopathologic findings. We examined the likelihood of diagnostic findings and of cancer with increasing numbers of nondiagnostic evaluations with their exact binomial confidence intervals [CIs] and potential predictors of nondiagnostic status using generalized estimating equations. Results: During the six-year period, 2234 unique individuals underwent ultrasound-guided FNAB of a thyroid nodule. The probability of obtaining a diagnostic biopsy declined from 84.4% [95% CI 82.8-85.8%] for initial FNABs to 57.6% [CI 50.8-64.2%] for the first re-FNAB and further to 42.4% [CI 25.5-60.8%] for second re-FNABs. Adjusted risk of nondiagnostic FNAB strongly increased with increasing numbers of previous biopsies and was also higher among whites. The overall rate of diagnosis of malignancy after a nondiagnostic FNAB was 8.1% [CI 4.2-13.7%] and was similar regardless of the number of previous nondiagnostic aspirations. Conclusion: Following an initial nondiagnostic FNAB, the probability of yielding a diagnostic result declines with each sequential repeat FNAB. Nonetheless, a tangible possibility of malignancy remains even after repeated nondiagnostic FNABs.

BACKGROUND: Diagnostic errors result in preventable morbidity and mortality. The outpatient setting may be at increased risk, where time constraints, the indolent nature of outpatient complaints and single decision-maker practice models predominate. METHODS: We developed a self-administered diagnostic pause to address diagnostic error. Clinicians (physicians and nurse practitioners) in an academic primary care setting received the tool if they were seeing urgent care patients who had previously been seen in the past two weeks in urgent care. We used pre-post-intervention surveys, focus groups and chart audits 6 months after the urgent care visit to assess the impact of the intervention on participant perceptions and actions. RESULTS: We piloted diagnostic pauses in two phases (3 months and 6 months, respectively); 9 physicians participated in the first phase, and 16 physicians and 2 nurse practitioners in the second phase. Subjects received 135 alerts for diagnostic pauses and responded to 82 (61% response). Thirteen per cent of alerts resulted in clinicians reporting new actions as a result of the diagnostic pauses. Thirteen per cent of cases at a 6-month chart audit resulted in diagnostic discrepancies, defined as differences in diagnosis from the initial working diagnosis. Focus groups reported that the diagnostic pauses were brief and fairly well integrated into the overall workflow for evaluation but would have benefited as a real-time application for patients at higher risk for diagnostic error. CONCLUSION: This pilot represents the first known examination of diagnostic pauses in the outpatient setting, and this work potentially paves the way for more broad-based systems and/or electronic interventions to address diagnostic error.

BACKGROUND: There are few published quality metrics relevant to fine-needle aspirations (FNA) of the thyroid and endocrinology. With the development of a Thyroid Nodule Clinic within an academic practice, the Division of Endocrinology, in collaboration with the Department of Medicine Quality Improvement Team, established a system to monitor the results and follow-up of thyroid biopsies to ensure patient safety and to prevent adverse clinical outcomes attributable to delayed or incomplete follow-up. METHODS: All FNA performed are identified using billing data from the Thyroid Nodule Clinic. Results were followed using the Beth Israel Deaconess Online Medical Record (OMR) system, and information is collected on documented follow-up plan and actions taken. Missing data are flagged for review. Over the reporting period, the monitoring process and categories were modified to account for adoption of the Bethesda reporting criteria and implementation of gene expression classifier testing. Specific workflow plans were developed for each cytopathologic classification. RESULTS: Between July 2007 and June 2014, 3895 FNAs were performed. The quality improvement tracking process found that 3856/3895 (99%) biopsy cases had documented follow-up since initiation of the project. CONCLUSION: This monitoring process has ensured quality patient care, with confidence that patients having FNAs are receiving documented necessary follow-up for treatment of their nodular conditions. This system serves as a potential model for others to use in their endocrine practice in managing the results of thyroid nodule biopsies.

Obesity is a growing health problem in our society and its treatment has been challenging. In recent decades, several anti-obesity drugs have been withdrawn from the market because of reported and documented adverse effects. After years of interruption, the US Food and Drug Administration (FDA) has recently approved multiple new anti-obesity drugs. The majority of these medications are taken orally, and only one is administered subcutaneously. In this article, we review the efficacy, adverse effects, and mechanism of action of all 5 FDA-approved drugs.

Alzheimer's disease is the most common cause of dementia and occurs commonly in patients 65 and older. There is an urgent need to find an effective management that could help prevent or at least slow down the progress of this major public health problem. Cholesterol related pathways might play a role in the pathogenesis of Alzheimer's disease. Treatment with 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) has been suggested to promote the prevention of Alzheimer's disease. In this review, we discuss potential pathogenetic pathways for the development of Alzheimer's disease and review the evidence regarding the value of statins as a strategy to prevent or delay progression of Alzheimer's disease.

OBJECTIVES: To determine whether a bundled intervention can increase detection of delirium and facilitate safer use of high-risk medications. DESIGN: Pre-post interventional trial. SETTING: Large academic medical center. PARTICIPANTS: Individuals aged 70 and older (n = 19,949) admitted between May 1, 2008, September 30, 2011. Individuals aged 80 and older admitted after April 26, 2010, received the intervention, those aged 80 and older admitted before were primary controls, and those aged 70 to 79 were concurrent controls. INTERVENTION: The intervention uses a checklist promoting delirium prevention, recognition and management, and modifies the computerized provider order entry system to provide care focused on elderly adults. MEASUREMENTS: Frequency of orders for activating the rapid response team for altered mental status, frequency of orders for haloperidol in excess of 0.5 mg or intravenous (IV) morphine in excess of 2 mg, and discharge disposition. RESULTS: Participants receiving the intervention had a mean age of 86.1 ± 4.6; 58.2% were female. The number of orders to activate the rapid response team for altered mental status increased in participants receiving the bundle and in controls (odds ratio (OR) for the difference of differences = 1.23 (95% confidence interval (CI) = 0.68-2.24, P = .49)). Participants receiving the bundle were less likely to receive more than 0.5 mg of IV, intramuscular, or oral haloperidol (OR = 0.60, 95% CI = 0.39-0.91, P = .02) and more than 2 mg of IV morphine (OR = 0.52, 95% CI = 0.42-0.63, P < .001). Participants who received the bundle were more likely to be discharged home than to extended care facilities (OR = 1.18, 95% CI = 1.04-1.35, P = .01). CONCLUSION: An intervention focused on delirium prevention and recognition by bedside staff combined with computerized decision support facilitates safer prescribing of high-risk medications and possibly results in less need for extended care.

OBJECTIVE: The objective of this study was to determine adherence to incidentally detected lung nodule computed tomographic (CT) surveillance recommendations and identify demographic and clinical factors that increase the likelihood of CT surveillance. MATERIALS AND METHODS: A total of 419 patients with incidentally detected lung nodules were included. Recorded data included patient demographic, radiologic, and clinical characteristics and outcomes at a 4-year follow-up. Multivariate logistic regression models determined the factors associated with likelihood of recommended CT surveillance. RESULTS: At least 1 recommended surveillance chest CT was performed on 48% of the patients (148/310). Computed tomographic result communication to the patient (odds ratio [OR], 2.2; P = 0.006; confidence interval [CI], 1.3-4.0) or to the referring physician (OR, 2.8; P = 0.001; CI, 1.7-4.5) and recommendation of a specific surveillance time interval (OR, 1.7; P = 0.023; CI, 1.08-2.72) increased the likelihood of surveillance. Other demographic, radiologic, and clinical factors did not influence surveillance. CONCLUSIONS: Documented physician and patient result communication as well as the recommendation of a specific surveillance time interval increased the likelihood of CT surveillance of incidentally detected lung nodules.

BACKGROUND & AIMS: Few studies have analyzed the safety of endoscopy in patients with inflammatory bowel disease (IBD). We aimed to determine the prevalence of procedure-related complications among these patients, compared with the general population, and estimate the lifetime risk of colonoscopy-related complications. METHODS: We collected data on complications in 685 patients with IBD and 17,000 patients without IBD (controls) using an automated system to track all emergency department visits to the Beth Israel Deaconess Medical Center within 14 days of an endoscopic procedure, from March 1, 2007, to November 30, 2007. We reviewed charts of all IBD patients to determine health care use (telephone calls or visits to a gastroenterologist or primary care physician and visits to other emergency departments or hospitals) after endoscopy. The lifetime risk of procedure-related complications was estimated using a Markov Monte Carlo model. RESULTS: Rates of complications were 1.17% among patients with IBD and 0.96% among controls (P = .55). The chart review showed that 3.8% of the IBD cohort received medical care within 14 days of the endoscopic procedure. Based on a Markov Monte Carlo simulation model, the lifetime risk of complications after a surveillance colonoscopy protocol was 12.7% among patients with IBD and 2.0% in the general population undergoing screening colonoscopy (P < .001). CONCLUSIONS: Although the risk of adverse events after each endoscopic procedure was similar for patients with IBD and the general population, IBD patients have an increased lifetime risk of complications after colonoscopies. A higher percentage of patients with IBD also seek medical care after endoscopic procedures than controls.
