Do patients who read visit notes on the patient portal have a higher rate of "loop closure" on diagnostic tests and referrals in primary care? A retrospective cohort study.

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.

Low Rate of Completion of Recommended Tests and Referrals in an Academic Primary Care Practice with Resident Trainees.

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.

Completion of Recommended Tests and Referrals in Telehealth vs In-Person Visits.

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.

Risk Factors for Opioid-Related Adverse Drug Events Among Older Adults After Hospitalization for Major Orthopedic Procedures.

OBJECTIVES: Older adults undergoing orthopedic procedures are commonly discharged from the hospital on opioids, but risk factors for postdischarge opioid-related adverse drug events (ORADEs) have not been previously examined. We aimed to identify risk factors for ORADEs after hospital discharge following orthopedic procedures. METHODS: This is a retrospective cohort study of a national sample of Medicare beneficiaries 65 years or older, who underwent major orthopedic surgery during hospitalization in 2016 and had an opioid fill within 2 days of discharge. We excluded beneficiaries with hospice claims and those admitted from or discharged to a facility. We used billing codes and medication claims to define potential ORADEs requiring a hospital revisit within 30 days of discharge. RESULTS: Among 30,514 hospitalizations with a major orthopedic procedure (89.7% arthroplasty, 5.6% treatment of fracture of dislocation, 4.7% other) and an opioid claim, a potential ORADE requiring hospital revisit occurred in 750 (2.5%). Independent risk factors included age of 80 years or older (hazard ratio [HR], 1.65; 95% confidence interval, 1.38-1.97), female sex (HR, 1.34 [1.16-1.56]), and clinical conditions, including heart failure (HR, 1.34 [1.10-1.62]), respiratory illness (HR, 1.23 [1.03-1.46]), kidney disease (HR, 1.23 [1.04-1.47]), dementia/delirium (HR, 1.63 [1.26-2.10]), anxiety disorder (HR, 1.42 [1.18-1.71]), and musculoskeletal/nervous system injuries (HR, 1.54 [1.24-1.90]). Prior opioid use, coprescribed sedating medications, and opioid prescription characteristics were not associated with ORADEs after adjustment for patient characteristics. CONCLUSIONS: Potential ORADEs occurred in 2.5% of older adults discharged with opioids after orthopedic surgery. These risk factors can inform clinician decision making, conversations with older adults, and targeting of harm reduction strategies.

Changes in the Use of Long-Term Medications Following Incident Dementia Diagnosis.

Importance: Dementia is a life-altering diagnosis that may affect medication safety and goals for chronic disease management. Objective: To examine changes in medication use following an incident dementia diagnosis among community-dwelling older adults. Design, Setting, and Participants: In this cohort study of adults aged 67 years or older enrolled in traditional Medicare and Medicare Part D, patients with incident dementia diagnosed between January 2012 and December 2018 were matched to control patients based on demographics, geographic location, and baseline medication count. The index date was defined as the date of first dementia diagnosis or, for controls, the date of the closest office visit. Data were analyzed from August 2021 to June 2023. Exposure: Incident dementia diagnosis. Main Outcomes and Measures: The main outcomes were overall medication counts and use of cardiometabolic, central nervous system (CNS)-active, and anticholinergic medications. A comparative time-series analysis was conducted to examine quarterly changes in medication use in the year before through the year following the index date. Results: The study included 266 675 adults with incident dementia and 266 675 control adults; in both groups, 65.1% were aged 80 years or older (mean [SD] age, 82.2 [7.1] years) and 67.8% were female. At baseline, patients with incident dementia were more likely than controls to use CNS-active medications (54.32% vs 48.39%) and anticholinergic medications (17.79% vs 15.96%) and less likely to use most cardiometabolic medications (eg, diabetes medications, 31.19% vs 36.45%). Immediately following the index date, the cohort with dementia had a greater increase in mean number of medications used (0.41 vs -0.06; difference, 0.46 [95% CI, 0.27-0.66]) and in the proportion of patients using CNS-active medications (absolute change, 3.44% vs 0.79%; difference, 2.65% [95% CI, 0.85%-4.45%]) owing to an increased use of antipsychotics, antidepressants, and antiepileptics. The cohort with dementia also had a modestly greater decline in use of anticholinergic medications (quarterly change in use, -0.53% vs -0.21%; difference, -0.32% [95% CI, -0.55% to -0.08%]) and most cardiometabolic medications (eg, quarterly change in antihypertensive use: -0.84% vs -0.40%; difference, -0.44% [95% CI, -0.64% to -0.25%]). One year after diagnosis, 75.2% of the cohort with dementia were using 5 or more medications (2.8% increase). Conclusions and Relevance: In this cohort study of Medicare Part D beneficiaries, following an incident dementia diagnosis, patients were more likely to initiate CNS-active medications and modestly more likely to discontinue cardiometabolic and anticholinergic medications compared with the control group. These findings suggest missed opportunities to reduce burdensome polypharmacy by deprescribing long-term medications with high safety risks or limited likelihood of benefit or that may be associated with impaired cognition.

Initiation of Long-Acting Opioids Following Hospital Discharge Among Medicare Beneficiaries.

Guidelines recommend against initiating long-acting opioids during acute hospitalization, owing to higher risk of overdose and morbidity compared to short-acting opioid initiation. We investigated the incidence of long-acting opioid initiation following hospitalization in a retrospective cohort of Medicare beneficiaries with an acute care hospitalization in 2016 who were ≥65 years old, did not have cancer or hospice care, and had not filled an opioid prescription within the preceding 90 days. Among 258,193 hospitalizations, 47,945 (18.6%) were associated with a claim for a new opioid prescription in the week after hospital discharge: 817 (0.3%) with both short- and long-acting opioids, 125 (0.1%) with long-acting opioids only, and 47,003 (18.2%) with short-acting opioids only. Most long-acting opioid claims occurred in surgical patients (770 out of 942; 81.7%). Compared with beneficiaries prescribed short-acting opioids only, beneficiaries prescribed long-acting opioids were younger, had a higher prevalence of diseases of the musculoskeletal system and connective tissue, and had more known risk factors for opioid-related adverse events, including anxiety disorders, opioid use disorder, prior long-term high-dose opioid use, and benzodiazepine co-prescription. These findings may help target quality-improvement initiatives.

Trends in Low-Value Carotid Imaging in the Veterans Health Administration From 2007 to 2016.

Importance: As part of the Choosing Wisely campaign, primary care, surgery, and neurology societies have identified carotid imaging ordered for screening, preoperative evaluation, and syncope as frequently low value. Objective: To determine the changes in overall and indication-specific rates of carotid imaging following Choosing Wisely recommendations. Design, Setting, and Participants: This serial cross-sectional study compared annual rates of carotid imaging before Choosing Wisely recommendations (ie, 2007 to 2012) and after (ie, 2013 to 2016) among adults receiving care in the Veterans Health Administration (VHA) national health system. Data analysis was performed from April 10, 2019, to November 27, 2019. Exposures: Release of the Choosing Wisely recommendations. Main Outcomes and Measures: Annual rates of overall imaging, imaging ordered for stroke workup, imaging ordered for low-value indications (ie, screening owing to carotid bruit, preoperative evaluation, and syncope). Indications were identified using a text lexicon algorithm based on electronic health record review of a stratified random sample of 1000 free-text imaging orders. The subsequent performance of carotid procedures within 6 months after carotid imaging was assessed. Results: Between 2007 and 2016, 809 071 carotid imaging examinations were identified (mean [SD] age of patients undergoing imaging, 69 [10] years; 776 632 [96%] men), of which 201 467 images (24.9%) were ordered for low-value indications (67 064 [8.2%] for carotid bruit, 25 032 [3.1%] for preoperative evaluation, and 109 400 [13.5%] for syncope), 257 369 (31.8%) for stroke workup, and 350 235 (43.3%) for other indications. Imaging for carotid bruits declined across the study period while there was no significant change in imaging for syncope or preoperative evaluation. Compared with the 6 years before, during the 4 years following Choosing Wisely recommendations, there was no change in the trend for syncope, a small decline in preoperative imaging (post-Choosing Wisely trend, -0.1 [95% CI, -0.1 to <-0.1] images per 10 000 veterans), and a continued but less steep decline in imaging for carotid bruits (post-Choosing Wisely trend, -0.3 [95% CI, -0.3 to -0.2] images per 10 000 veterans). During the study period, 17 689 carotid procedures were identified, of which 3232 (18.3%) were preceded by carotid imaging ordered for low-value indications. Conclusions and Relevance: These findings suggest that Choosing Wisely recommendations were not associated with a meaningful change in low-value carotid imaging in a national integrated health system. To reduce low-value testing and utilization cascades, interventions targeting ordering clinicians are needed to augment the impact of public awareness campaigns.

Physician Perspectives on Deprescribing Cardiovascular Medications for Older Adults.

BACKGROUND/OBJECTIVES: Guideline-based management of cardiovascular disease often involves prescribing multiple medications, which contributes to polypharmacy and risk for adverse drug events in older adults. Deprescribing is a potential strategy to mitigate these risks. We sought to characterize and compare clinician perspectives regarding deprescribing cardiovascular medications across three specialties. DESIGN: National cross-sectional survey. SETTING: Ambulatory. PARTICIPANTS: Random sample of geriatricians, general internists, and cardiologists from the American College of Physicians. MEASUREMENTS: Electronic survey assessing clinical practice of deprescribing cardiovascular medications, reasons and barriers to deprescribing, and choice of medications to deprescribe in hypothetical clinical cases. RESULTS: In each specialty, 750 physicians were surveyed, with a response rate of 26% for geriatricians, 26% for general internists, and 12% for cardiologists. Over 80% of respondents within each specialty reported that they had recently considered deprescribing a cardiovascular medication. Adverse drug reactions were the most common reason for deprescribing for all specialties. Geriatricians also commonly reported deprescribing in the setting of limited life expectancy. Barriers to deprescribing were shared across specialties and included concerns about interfering with other physicians' treatment plans and patient reluctance. In hypothetical cases, over 90% of physicians in each specialty chose to deprescribe when patients experienced adverse drug reactions. Geriatricians were most likely and cardiologists were least likely to consider deprescribing cardiovascular medications in cases of limited life expectancy (all P < .001), such as recurrent metastatic cancer (84% of geriatricians, 68% of general internists, and 45% of cardiologists), Alzheimer dementia (92% of geriatricians, 81% of general internists, and 59% of cardiologists), or significant functional impairment (83% of geriatricians, 68% of general internists, and 45% of cardiologists). CONCLUSIONS: While barriers to deprescribing cardiovascular medications are shared across specialties, reasons for deprescribing, especially in the setting of limited life expectancy, varied. Implementing deprescribing will require improved processes for both physician-physician and physician-patient communication. J Am Geriatr Soc 68:78-86, 2019.

Iron Complexes for Cyclic Carbonate and Polycarbonate Formation: Selectivity Control from Ligand Design and Metal-Center Geometry.

A family of 17 iron(III) aminobis(phenolate) complexes possessing different phenolate substituents, coordination geometries, and donor arrangements were used as catalysts for the reaction of carbon dioxide (CO2) with epoxides. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry of the iron complexes with a bis(triphenylphosphine)iminium chloride cocatalyst in negative mode revealed the formation of six-coordinate iron "ate" species. Under low catalyst loadings (0.025 mol % Fe and 0.1 mol % chloride cocatalyst), all complexes showed good-to-excellent activity for converting propylene oxide to propylene carbonate under 20 bar of CO2. The most active complex possessed electron-withdrawing dichlorophenolate groups and for a 2 h reaction time gave a turnover frequency of 1240 h-1. Epichlorohydrin, styrene oxide, phenyl glycidyl ether, and allyl glycidyl ether could also be transformed to their respective cyclic carbonates with good-to-excellent conversions. Selectivity for polycarbonate formation was observed using cyclohexene oxide, where the best activity was displayed by trigonal-bipyramidal iron(III) complexes having electron-rich phenolate groups and sterically unencumbering tertiary amino donors. Those containing bulky tertiary amino ligands or those with square-pyramidal geometries around iron showed no activity for polycarbonate formation. While the overall conversions declined with decreasing CO2 pressure, CO2 incorporation remained high, giving a completely alternating copolymer. The difference in the optimum catalyst reactivity for cyclic carbonate versus polycarbonate formation is particularly noteworthy; that is, electron-withdrawing-group-containing phenolates give the most active catalysts for propylene carbonate formation, whereas catalysts with electron-donating-group-containing phenolates are the most active for polycyclohexene carbonate formation. This study demonstrates that the highly modifiable aminophenolate ligands can be tailored to yield iron complexes for both CO2/epoxide coupling and ring-opening copolymerization activity.

Deprescribing in Older Adults With Cardiovascular Disease.

Deprescribing, an integral component of a continuum of good prescribing practices, is the process of medication withdrawal or dose reduction to correct or prevent medication-related complications, improve outcomes, and reduce costs. Deprescribing is particularly applicable to the commonly encountered multimorbid older adult with cardiovascular disease and concomitant geriatric conditions such as polypharmacy, frailty, and cognitive dysfunction-a combination rarely addressed in current clinical practice guidelines. Triggers to deprescribe include present or expected adverse drug reactions, unnecessary polypharmacy, and the need to align medications with goals of care when life expectancy is reduced. Using a framework to deprescribe, this review addresses the rationale, evidence, and strategies for deprescribing cardiovascular and some noncardiovascular medications.

Intensification of older adults' outpatient blood pressure treatment at hospital discharge: national retrospective cohort study.

OBJECTIVES: To assess how often older adults admitted to hospital for common non-cardiac conditions were discharged with intensified antihypertensive treatment, and to identify markers of appropriateness for these intensifications. DESIGN: Retrospective cohort study. SETTING: US Veterans Administration Health System. PARTICIPANTS: Patients aged 65 years or over with hypertension admitted to hospital with non-cardiac conditions between 2011 and 2013. MAIN OUTCOME MEASURES: Intensification of antihypertensive treatment, defined as receiving a new or higher dose antihypertensive agent at discharge compared with drugs used before admission. Hierarchical logistic regression analyses were used to control for characteristics of patients and hospitals. RESULTS: Among 14 915 older adults (median age 76, interquartile range 69-84), 9636 (65%) had well controlled outpatient blood pressure before hospital admission. Overall, 2074 (14%) patients were discharged with intensified antihypertensive treatment, more than half of whom (1082) had well controlled blood pressure before admission. After adjustment for potential confounders, elevated inpatient blood pressure was strongly associated with being discharged on intensified antihypertensive regimens. Among patients with previously well controlled outpatient blood pressure, 8% (95% confidence interval 7% to 9%) of patients without elevated inpatient blood pressure, 24% (21% to 26%) of patients with moderately elevated inpatient blood pressure, and 40% (34% to 46%) of patients with severely elevated inpatient blood pressure were discharged with intensified antihypertensive regimens. No differences were seen in rates of intensification among patients least likely to benefit from tight blood pressure control (limited life expectancy, dementia, or metastatic malignancy), nor in those most likely to benefit (history of myocardial infarction, cerebrovascular disease, or renal disease). CONCLUSIONS: One in seven older adults admitted to hospital for common non-cardiac conditions were discharged with intensified antihypertensive treatment. More than half of intensifications occurred in patients with previously well controlled outpatient blood pressure. More attention is needed to reduce potentially harmful overtreatment of blood pressure as older adults transition from hospital to home.

Gynaecomastia in two men on stable antiretroviral therapy who commenced treatment for tuberculosis.

Gynaecomastia is a common clinical presentation that varies from benign presentations in stages of human development to hormonal pathology, mainly due to hepatic dysfunction, malignancy, and adverse pharmacologic effects. We describe the development of significant bilateral gynaecomastia after starting treatment for pulmonary tuberculosis (TB) in two males with WHO stage III Human Immunodeficiency Virus (HIV) infection on stable antiretroviral regimens. Emerging reports suggest that distinct hepatic impairment in efavirenz metabolism modulates oestrogenic activity, which may be potentiated by anti-tuberculosis therapy. Clinical application includes early recognition of efavirenz-induced gynaecomastia, especially after commencing tuberculosis treatment. To avoid decreased adherence resulting from the distressing side effect of gynecomastia, transition to an alternative ART regimen over the course of tuberculosis treatment should be considered.
