Cardiovascular and mortality benefits of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide 1 receptor agonists as third-step glucose-lowering medicine in patients with type 2 diabetes: a retrospective cohort analysis.

INTRODUCTION: Studies have found that sodium-glucose cotransporter 2 inhibitors (SGLT2) and glucagon-like peptide 1 receptor agonists (GLP1) have cardiovascular benefits for patients with type 2 diabetes (DM2) and atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), or heart failure (HF). The literature does not provide evidence specifically for patients with these conditions who are adding one of these medicines to two glucose-lowering medications (ie, as "third-step" therapy). We explored the effects of different third-step medications on cardiovascular outcomes in patients with diabetes and these comorbid conditions. Specifically, we compared third-step SGLT2 or GLP1 to third-step dipeptidyl peptidase-4 inhibitors (DPP4), insulin, or thiazolidinediones (TZD). RESEARCH DESIGN AND METHODS: We assembled a retrospective cohort of adults at five Kaiser Permanente sites with DM2 and ASCVD, CKD, or HF, initiating third-step treatment between 2016 and 2020. Propensity score weighted Poisson models were used to calculate adjusted rate ratios (ARRs) for all-cause mortality, incident major adverse cardiovascular event (MACE), and incident HF hospitalization in patients initiating SGLT2 or GLP1 compared with DPP4, insulin, or TZD. RESULTS: We identified 27 542 patients initiating third-step treatment with one or more of these conditions (19 958 with ASCVD, 14 577 with CKD, and 3919 with HF). ARRs for GLP1 and SGLT2 versus DPP4, insulin, and TZD in the patient subgroups ranged between 0.22 and 0.55 for all-cause mortality, 0.38 and 0.81 for MACE, and 0.46 and 1.05 for HF hospitalization. Many ARRs were statistically significant, and all significant ARRs showed a benefit (ARR <1) for GLP1 or SGLT2 when compared with DPP4, insulin, or TZD. CONCLUSIONS: Third-step SGLT2 and GLP1 are generally associated with a benefit for these outcomes in these patient groups when compared with third-step DPP4, insulin, or TZD. Our results add to evidence of a cardiovascular benefit of SGLT2 and GLP1 and could inform clinical guidelines for choosing third-step diabetes treatment.

Incidence of Diabetes Among Youth Before and During the COVID-19 Pandemic.

Importance: Prior research found increases in diabetes among youth during the COVID-19 pandemic, but few studies examined variation across sociodemographics. Objective: To examine diabetes incidence rates among a diverse population of youth in the US before and during the COVID-19 pandemic. Design, Setting, and Participants: This cohort study included data from Kaiser Permanente Southern California (KPSC) between January 1, 2016, and December 31, 2021. KPSC members aged from birth to 19 years with no history of diabetes were included. Individuals were followed up using electronic health records for diabetes incidence defined using diagnoses, laboratory values, and medications. Analyses were conducted between November 2022 and January 2023. Main Outcome and Measures: Age- and sex-standardized annual and quarterly incidence rates per 100 000 person-years (PYs) were calculated for type 1 diabetes and type 2 diabetes between 2016 and 2021. Rates were calculated within strata of age (<10 and 10-19 years), sex, and race and ethnicity (Asian/Pacific Islander, Hispanic, non-Hispanic Black, non-Hispanic White, and other/multiple/unknown). Using Poisson regression with robust error variances, incidence rate ratios (IRR) comparing 2020 to 2021 with 2016 to 2019 were calculated by diabetes type and within age, sex, and race and ethnicity strata and adjusting for health care utilization. Results: Between 2016 to 2021, there were 1200, 1100, and 63 patients with type 1 diabetes (mean [SD] age, 11.0 [4.5] years; 687 [57.3%] male), type 2 diabetes (mean [SD] age, 15.7 [2.7] years; 516 [46.9%] male), and other diabetes, respectively. Incidence of type 1 diabetes increased from 18.5 per 100 000 PYs in 2016 to 2019 to 22.4 per 100 000 PYs from 2020 to 2021 with increased IRRs among individuals aged 10 to 19 years, male individuals, and Hispanic individuals. Incidence of type 2 diabetes increased from 14.8 per 100 000 PYs from 2016 to 2019 to 24.7 per 100 000 PYs from 2020 to 2021 with increased IRRs among individuals aged 10 to 19 years, male and female individuals, and those with Black, Hispanic, and other/unknown race and ethnicity. Conclusions and Relevance: In this cohort study of youth in KPSC, incidence of diabetes increased during the COVID-19 pandemic and was more pronounced in specific racial and ethnic groups. Future research to understand differential impacts of physiologic and behavioral risk factors is warranted.

Risk of hospitalization and mortality associated with uncontrolled blood pressure in patients with hypertension and COVID-19.

OBJECTIVE: The role of uncontrolled blood pressure (BP) in COVID-19 severity among patients with hypertension is unclear. We evaluated the association between uncontrolled BP and the risk of hospitalization and/or mortality in patients with hypertension from a large US integrated healthcare system. METHODS: We identified patients with hypertension and a positive RT-PCR test result or a diagnosis of COVID-19 between March 1 - September 1, 2020 from Kaiser Permanente Southern California. BP categories was defined using the most recent outpatient BP measurement during 12 months prior to COVID-19 infection. The primary outcome of interest was all-cause hospitalization or mortality within 30 days from COVID-19 infection. RESULTS: Among 12,548 patients with hypertension and COVID-19 (mean age = 60 years, 47% male), 63% had uncontrolled BP (≥130/80 mm Hg) prior to COVID-19. Twenty-one percent were hospitalized or died within 30 days of COVID-19 infection. Uncontrolled BP was not associated with higher hospitalization or mortality (adjusted rate ratios for BP ≥ 160/100 mm Hg vs < 130/80 mm Hg = 1.00 [95% CI: 0.87, 1.14]; BP 140-159/90-99 mm Hg vs < 130/80 mm Hg = 1.02 [95% CI: 0.93, 1.11]). These findings were consistent across different age groups, treatment for antihypertensive medications, as well as atherosclerotic cardiovascular disease risk. CONCLUSION: Among patients with hypertension, uncontrolled BP prior to COVID-19 infection did not appear to be an important risk factor for 30-day mortality or hospitalization.

COVID-19 morbidity and mortality associated with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers use among 14,129 patients with hypertension from a US integrated healthcare system.

OBJECTIVE: Although recent evidence suggests no increased risk of severe COVID-19 outcomes associated with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) use, the relationship is less clear among patients with hypertension and diverse racial/ethnic groups. This study evaluates the risk of hospitalization and mortality among patients with hypertension and COVID-19 in a large US integrated healthcare system. METHODS: Patients with hypertension and COVID-19 (between March 1- September 1, 2020) on ACEIs or ARBs were compared with patients on other frequently used antihypertensive medications. RESULTS: Among 14,129 patients with hypertension and COVID-19 infection (mean age 60 years, 48% men, 58% Hispanic), 21% were admitted to the hospital within 30 days of COVID-19 infection. Of the hospitalized patients, 24% were admitted to intensive care units, 17% required mechanical ventilation, and 10% died within 30 days of COVID-19 infection. Exposure to ACEIs or ARBs prior to COVID-19 infection was not associated with an increased risk of hospitalization or all-cause mortality (rate ratios for ACEIs vs other antihypertensive medications â€‹= â€‹0.98, 95% CI: 0.88, 1.08; ARBs vs others â€‹= â€‹1.00, 95% CI: 0.90, 1.11) after applying inverse probability of treatment weights. These associations were consistent across racial/ethnic groups. Use of ACEIs or ARBs during hospitalization was associated with a lower risk of all-cause mortality (odds ratios for ACEIs or ARBs vs others â€‹= â€‹0.50, 95% CI: 0.34, 0.72). CONCLUSION: Our study findings support continuation of ACEI or ARB use for patients with hypertension during the COVID-19 pandemic and after COVID-19 infection.

Low Referral Rates for Genetic Assessment of Patients With Multiple Adenomas in United Kingdom Bowel Cancer Screening Programs.

BACKGROUND: Approximately 1 in 20 cases of colorectal cancer are caused by monogenic syndromes. Published guidelines recommend that patients with 10 or more adenomas be referred for genetic testing, based on evidence that colorectal cancer risk is associated with adenoma multiplicity. OBJECTIVE: The aim of this study was to determine adherence to guidelines on referral for genetic screening in patients with 10 or more adenomas. DESIGN: A cross-sectional study was performed of prospectively collected data from the UK Bowel Cancer Screening Programme between May 2007 and June 2018. Only histologically confirmed adenomas were included. Clinicopathological data were recorded from patient records, and referrals to clinical genetics services were ascertained. SETTING: Data were obtained from 3 centers in London, United Kingdom. PATIENTS: A total of 17,450 subjects underwent colonoscopy following an abnormal fecal occult blood test. MAIN OUTCOME MEASURES: We quantified patients with 10 or more adenomas and the proportion referred for genetic screening. RESULTS: The adenoma detection rate was 50.6% among 17,450 patients who underwent colonoscopy (8831 had 1 or more adenomas). Three hundred forty-seven patients (2.0%) had 10 or more adenomas. Patients with 10 or more adenomas were more likely to be male than those with fewer than 10 adenomas (76.9% vs 53.4%; p < 0.0001). A family history was collected in 37.8% of the multiple adenoma population. Of 347 patients with 10 or more adenomas, 28 (8.1%) were referred for genetic assessment. LIMITATIONS: All 3 screening centers were in a single city. No genetic outcome data were available to permit analysis of actual rates of inherited cancer syndromes in this population. CONCLUSIONS: In this study, almost 1 in 50 patients had 10 or more adenomas. Despite guidelines advising genetic testing in this group, referral rates are low. A referral pathway and management strategies should be established to address this patient population. See Video Abstract at http://links.lww.com/DCR/B630. TASAS BAJAS DE DERIVACIN PARA LA EVALUACIN GENTICA DE PACIENTES CON ADENOMAS MLTIPLES EN LOS PROGRAMAS DE DETECCIN DEL CNCER DE INTESTINO DEL REINO UNIDO: ANTECEDENTES:Aproximadamente uno de cada veinte casos de cáncer colorrectal son causados por síndromes monogénicos. Las pautas publicadas recomiendan que los pacientes con diez o más adenomas sean derivados para pruebas genéticas, basándose en la evidencia de que el riesgo de cáncer colorrectal está asociado con la multiplicidad de adenomas.OBJETIVO:El objetivo de este estudio fue determinar la adherencia a las guías de derivación para cribado genético en pacientes con diez o más adenomas.DISEÑO:Se realizó un estudio transversal de datos recolectados prospectivamente del Programa de Detección de Cáncer de Intestino del Reino Unido entre mayo de 2007 y junio de 2018. Solo se incluyeron los adenomas confirmados histológicamente. Los datos clínico-patológicos se registraron a partir de los registros de los pacientes y se determinaron las derivaciones a los servicios de genética clínica.AJUSTE ENTORNO CLINICO:Los datos se obtuvieron de tres centros en Londres, Reino Unido.PACIENTES:Un total de 17.450 17450 sujetos pacientes se sometieron a una colonoscopia después de una prueba de sangre oculta en heces anormal positiva.PRINCIPALES MEDIDAS DE RESULTADO VOLARACION:cuantificamos los pacientes con diez o más adenomas y la proporción remitida para cribado genético.RESULTADOS:La tasa de detección de adenomas fue del 50,6% entre 17.450 17450 pacientes que se sometieron a colonoscopia (8.831 8831 tenían uno o más adenomas). 347 pacientes (2,0%) tenían 10 o más adenomas. Los pacientes con 10 o más adenomas tenían más probabilidades de ser hombres que aquellos con menos de 10 adenomas (76,9% frente versus a 53,4%; p <0,0001). Se recogieron antecedentes familiares en el 37,8% de la población de adenomas múltiples. De 347 pacientes con 10 o más adenomas, 28 (8,1%) fueron remitidos para evaluación genética.LIMITACIONES:Los tres centros de detección se encontraban en una sola ciudad. No se disponía de datos de resultados genéticos que permitieran el análisis de las tasas reales de síndromes de cáncer hereditario en esta población.CONCLUSIONES:En este estudio, casi uno de cada cincuenta pacientes tenía diez o más adenomas. A pesar de las pautas que recomiendan las pruebas genéticas en este grupo, las tasas de derivación son bajas. Se debe establecer una vía de derivación y estrategias de manejo para abordar esta población de pacientes. Consulte Video Resumen en http://links.lww.com/DCR/B630.

Angiotensin-Converting Enzyme Inhibitors or Angiotensin Receptor Blockers Use and COVID-19 Infection Among 824 650 Patients With Hypertension From a US Integrated Healthcare System.

Background Previous reports suggest that the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) may upregulate angiotensin-converting enzyme 2 receptors and increase severe acute respiratory syndrome coronavirus 2 infectivity. We evaluated the association between ACEI or ARB use and coronavirus disease 2019 (COVID-19) infection among patients with hypertension. Methods and Results We identified patients with hypertension as of March 1, 2020 (index date) from Kaiser Permanente Southern California. Patients who received ACEIs, ARBs, calcium channel blockers, beta blockers, thiazide diuretics (TD), or no therapy were identified using outpatient pharmacy data covering the index date. Outcome of interest was a positive reverse transcription polymerase chain reaction test for COVID-19 between March 1 and May 6, 2020. Patient sociodemographic and clinical characteristics were identified within 1 year preindex date. Among 824 650 patients with hypertension, 16 898 (2.0%) were tested for COVID-19. Of those tested, 1794 (10.6%) had a positive result. Overall, exposure to ACEIs or ARBs was not statistically significantly associated with COVID-19 infection after propensity score adjustment (odds ratio [OR], 1.06; 95% CI, 0.90-1.25) for ACEIs versus calcium channel blockers/beta blockers/TD; OR, 1.10; 95% CI, 0.91-1.31 for ARBs versus calcium channel blockers/beta blockers/TD). The associations between ACEI use and COVID-19 infection varied in different age groups (P-interaction=0.03). ACEI use was associated with lower odds of COVID-19 among those aged ≥85 years (OR, 0.30; 95% CI, 0.12-0.77). Use of no antihypertensive medication was significantly associated with increased odds of COVID-19 infection compared with calcium channel blockers/beta blockers/TD (OR, 1.32; 95% CI, 1.11-1.56). Conclusions Neither ACEI nor ARB use was associated with increased likelihood of COVID-19 infection. Decreased odds of COVID-19 infection among adults ≥85 years using ACEIs warrants further investigation.

Age-Dependent Hemoglobin A1c Therapeutic Targets Reduce Diabetic Medication Changes in the Elderly.

OBJECTIVE: To assess whether implementation of age-dependent therapeutic targets for high hemoglobin A1c (HbA1c) changed clinicians' ordering of diabetes medications for older adults. BACKGROUND: In 2016, Kaiser Permanente Southern California (KPSC) changed the therapeutic targets for alerting clinicians about high HbA1c results in the electronic health record, KP HealthConnect (KPHC). Previously, all HbA1c results ≥7.0 percent were flagged as high in adult patients with diabetes. Starting in 2016, HbA1c therapeutic targets were relaxed to <7.5 percent for patients age 65 to 75, and to <8.0 percent for patients over age 75 to reduce treatment intensity and adverse events. METHODS: This retrospective analysis used logistic regression models to calculate the change in odds of a medication change following an HbA1c result after age-dependent HbA1c flags were introduced. RESULTS: The odds of medication change decreased among patients whose HbA1c targets were relaxed: Odds Ratio (OR) 0.72 (95 percent CI 0.67-0.76) for patients age 65-75 and HbA1c 7.0 percent-7.5 percent; OR 0.72 (95 percent CI 0.65-0.80) for patients over age 75 and HbA1c 7.0 percent-7.5 percent; and OR 0.67 (95 percent CI 0.61-0.75) for patients over age 75 and HbA1c 7.5 percent-8.0 percent. In the age and HbA1c ranges for which the alerts did not change, the odds of medication change generally increased or stayed the same. There was little evidence of medication de-intensification in any group. CONCLUSIONS: These findings suggest that the change in therapeutic targets was associated with a reduction in medication intensification among older adults with diabetes.

Process-Based Treatment of Diabetes in Kaiser Permanente Southern California: How to Make Diabetes Care "Complete".

PURPOSE OF REVIEW: The purpose of this review was to provide an overview of the Kaiser Permanente Southern California (KPSC) Complete Care management strategy. RECENT FINDINGS: The KPSC Complete Care program allows members of care management teams to coordinate the administration of care for patients with diabetes. This program encompasses teams of physicians, physician assistants, pharmacists, nurse practitioners, registered nurse (RN) care managers, office-based RNs, health educators, and many others to contribute to the glycemic and overall health outcomes for our patients with diabetes. The 2016 Kaiser Permanente National Clinical Practice Guideline for Adult Diabetes Clinician Guide and the supplemental KPSC Treat-to-Target (TTT) Type 2 Diabetes A1c Control algorithm are used to assist KPSC clinicians by providing guidance for shared decision-making, as well as the selection and sequence of appropriate pharmacological treatment. Collaboration with pharmacy through the Formulary and the Drug Utilization Action Team (DUAT) allows the organization to manage member resources while consistently offering patients the highest quality and value health care possible. Recent technology integrations have also contributed to the success of the program.

Treatment discontinuation of oral hypoglycemic agents and healthcare utilization among patients with diabetes.

AIMS: To investigate the discontinuation of oral antihyperglycemic agents (OHA), and examine factors associated with OHA discontinuation, and the effect of OHA discontinuation on glycemic control and healthcare utilization among diabetes patients prescribed dual OHA therapy. METHODS: We identified 23,612 adult patients aged >18years with a diagnosis of type 2 diabetes who initiated dual OHA therapy between 1/1/2005 and 6/30/2010. The date of initiation of the second OHA was defined as the index date. Discontinuation was defined as a gap >1.5 times the last days' supply without subsequent reinitiation. RESULTS: Over 24months, 16.9% discontinued 1 OHA and 9.2% discontinued both. Patients who discontinued were more likely to be female, younger, Black or of Hispanic ethnicity, have more comorbidities, higher medication co-pays, start both OHAs together, have higher healthcare utilization before the index date and less likely to use prescription mail order compared with patients who did not discontinue. In multivariable regression models, patients who discontinued were more likely to be hospitalized or have emergency department visits during follow-up. CONCLUSIONS: Discontinuation of OHAs is common among patients with diabetes and is associated with several patient factors and increased healthcare utilization. Future research should further examine reasons for OHA discontinuation.

Ground gas monitoring: implications for hydraulic fracturing and CO2 storage.

Understanding the exchange of carbon dioxide (CO2) and methane (CH4) between the geosphere and atmosphere is essential for the management of anthropogenic emissions. Human activities such as carbon capture and storage and hydraulic fracturing ("fracking") affect the natural system and pose risks to future global warming and to human health and safety if not engineered to a high standard. In this paper an innovative approach of expressing ground gas compositions is presented, using data derived from regulatory monitoring of boreholes in the unsaturated zone at infrequent intervals (typically 3 months) with data from a high frequency monitoring instrument deployed over periods of weeks. Similar highly variable trends are observed for time scales ranging from decades to hourly for boreholes located close to sanitary landfill sites. Additionally, high frequency monitoring data confirm the effect of meteorological controls on ground gas emissions; the maximum observed CH4 and CO2 concentrations in a borehole monitored over two weeks were 40.1% v/v and 8.5% v/v respectively, but for 70% of the monitoring period only air was present. There is a clear weakness in current point monitoring strategies that may miss emission events and this needs to be considered along with obtaining baseline data prior to starting any engineering activity.

Evaluation of a pharmacist-managed amiodarone monitoring program.

BACKGROUND: Because of the potential for serious adverse effects, patients treated with amiodarone must be carefully screened and routinely monitored for potential liver, thyroid, and pulmonary toxicity. However, laboratory and pulmonary monitoring rates have been found to be substantially lower than recommended in guidelines, including those of the North American Society of Pacing and Electrophysiology (NASPE, 2007). OBJECTIVE: To (a) assess rates of laboratory monitoring of liver, thyroid, and pulmonary function and adverse events in a pharmacist-managed amiodarone monitoring program compared with usual care in an integrated health care system and (b) estimate return on investment (ROI) from this intervention. METHODS: This retrospective cohort study used clinic and enrollment data to identify those patients in the pharmacist-managed program and usual care who received at least 100 days of amiodarone therapy with the first prescription for amiodarone (index) from June 1, 2007, through May 31, 2009 (index date). Laboratory test monitoring was recorded at baseline (up to 6 months before the index date), from 1-6 months after the index date, 7-12 months after the index date, and at any time during the year (months 1-12). Alanine aminotransferase (ALT) was evaluated for liver function. Thyroid-stimulating hormone (TSH) and, for patients with abnormal TSH ( less than 0.4 micro international units [uIU] per mL or greater than 4.0 uIU per mL), free thyroxine (T4) were evaluated for thyroid function. Rates of pulmonary function testing (PFT) were measured by the diffusion capacity of carbon monoxide tests (DLCO) and annual chest x-rays (CXR); electrocardiograms were not counted. Monitoring rates were compared using Pearson chi-square tests, and logistic regression was used to compare the odds of testing (ALT, TSH, T4, CXR, PFT) between the 2 groups at any time during the year after the index date. Concomitant uses of amiodarone with high-dose statins and of amiodarone with digoxin were compared using Pearson chi-square tests. Hospitalizations and emergency room (ER) visits during the 12-month follow-up period were counted for (a) interstitial lung disease; (b) rhabdomyolysis for patients who received amiodarone with high-dose statins (either lovastatin greater than 40 mg per day or greater than 20 mg per day of simvastatin or atorvastatin); and (c) for patients with abnormal digoxin, ALT, TSH, or T4 levels, if the hospitalization occurred within 2 days of the abnormal laboratory value. RESULTS: There were 2,292 patients who received at least 100 days of amiodarone therapy and met the other inclusion criteria, of whom 181 patients (7.9%) were in the pharmacist-managed group and 2,111 received usual care. There were 90 (49.7%) new amiodarone users in the pharmacist-managed group and 990 (46.9%) in usual care. The 2 groups had similar demographic characteristics except race, with more whites and fewer African Americans, Asians, and Hispanics in usual care. Laboratory monitoring rates for ALT, TSH, and T4 were significantly higher in the pharmacist-managed group than usual care at the first and second 6 months and at baseline for ALT and TSH but not T4. Baseline CXR rates were significantly higher for the pharmacist-managed group than usual care (59.1% vs. 49.3%; P=0.011). Few patients in either group received PFT tests at baseline, 6.6% versus 3.6% (P=0.042). After controlling for covariates (age, gender, race, new vs. continuing use, and comorbidities), pharmacist-managed patients were significantly more likely to have at least 1 ALT test within the year after the index prescription (odds ratio [OR]=3.13, 95% CI=1.12-8.71), as well as a TSH test (OR=8.13, 95% CI=3.27-20.21) and T4 (OR=2.51, 95% CI=1.67-3.75). PFTs were also more likely to be given to these patients (OR=5.89, 95% CI=3.86-8.99). A higher percentage of patients in the pharmacist-managed group than in usual care were taking a high-dose statin during the 12-month follow-up period (47.5% vs. 36.2%, P=0.003), but of those patients, a greater proportion were switched to another statin (14.0% [n=12] vs. 7.5% [n=57], P=0.037) or a lower dose (9.3% [n=8] vs. 3.9% [n=30], P=0.022). Six patients in the usual care group (0.79% of patients on high-dose statins) developed rhabdomyolysis, and 5 (0.24% of all patients in usual care) had an admission for interstitial lung disease. The proportions of patients using amiodarone and digoxin concomitantly were similar in the 2 groups (35.9% vs. 31.3%, P=0.197). Among patients with abnormal laboratory results for ALT, TSH, and T4, or digoxin, there were 2 all-cause hospitalizations and 1 ER visit in the pharmacist-managed group and 34 all-cause hospitalizations and 18 ER visits in the usual care group during the follow-up year. Assuming that all hospitalizations and ER visits incurred in the usual care group were avoid- able, approximately $2.14 could be saved for every dollar spent on the pharmacist-managed amiodarone monitoring program. CONCLUSIONS: Pharmacist management of patients treated with amiodarone was associated with improved monitoring of recommended laboratory tests and PFTs.
