Impact of opioid use on patients undergoing screening colonoscopy according to the quality of bowel preparation

AIMS: Constipation associated with opioid therapy for chronic pain may negatively impact colonoscopy success. This retrospective, observational study using administrative data and electronic medical records evaluated the impact of opioid use on colonoscopy outcomes. METHODS AND RESULTS: Procedural codes were used to identify patients who had a screening colonoscopy at two Henry Ford Health System centers (January 2015-December 2016). All patients had completed a standard uniform bowel preparation protocol. Medication orders and filled prescriptions were used to identify patients with a history of opioid use during the 28 days preprocedure (exposed) and a matched random sample of presumptive opioid nonusers (unexposed). Electronic medical records were reviewed for colonoscopy procedure data and outcomes.The exposed and unexposed groups included 964 and 1054 patients, respectively. Inadequate bowel preparation was significantly more common in the exposed versus unexposed group (18.5% vs 12.7%; P \u3c 0.001). In the exposed and unexposed groups, 97.1 and 98.0% of colonoscopy procedures were completed, respectively (P = nonsignificant). Total procedure time was slightly increased for the exposed versus unexposed group (23.8 vs 22.5 min; P = 0.039). Polyp identification and cancer diagnosis were similar between groups. Prolonged sedation occurred in three patients in the exposed group and none in the unexposed group. Procedural complications were rare, but the incidence was significantly greater in the exposed versus unexposed group (1.3% vs 0.2%; P \u3c 0.01). CONCLUSIONS: Opioid exposure was associated with significant reductions in the quality of preprocedure bowel preparation and an increased risk of complications in patients undergoing colonoscopy

Diabetes mellitus and hyperglycemia control on the risk of colorectal adenomatous polyps: a retrospective cohort study

BACKGROUND: Colorectal cancer (CRC) develops from colorectal adenomatous polyps. This study is to determine if diabetes mellitus (DM), its treatment, and hemoglobin A1c (HbA1c) level are associated with increased risk of colorectal adenomatous polyps. METHODS: This was a retrospective cohort study that included patients who had at least one colonoscopy and were continuously enrolled in a single managed care organization during a 10-year period (2002-2012). Of these patients (N = 11,933), 1800 were randomly selected for chart review to examine the details of colonoscopy and pathology findings and to confirm the diagnosis of DM. Multivariable logistic regression analyses were performed to assess the associations between DM, its treatment, HbA1c level and adenomatous polyps (our main outcome). RESULTS: Among the total of 11,933 patients with a mean (standard deviation) age of 56 (± 8.8) years, 2306 (19.3%) had DM and 75 (0.6%) had CRC. Among the 1800 under chart review, 445 (24.7%) had DM, 11 (0.6%) had CRC and 537 (29.8%) had adenomatous polyps. In bivariate analysis, patients with DM had 1.45 odds of developing adenomatous polyps compared to those without DM. This effect was attenuated (odds ratio = 1.25, 95% CI: 0.96-1.62, p = 0.09) after adjusting for confounders such as age, gender, race/ethnicity, and body mass index. There was no significant association between type or duration of DM treatment or HbA1c level and adenomatous polyps. CONCLUSIONS: Our study confirmed the known increased risk of adenomatous polyps with advancing age, male gender, Hispanic race/ethnicity and higher body mass index. Although it suggested an association between DM and adenomatous polyps, a statistically significant association was not observed after controlling for other potential confounders. Further studies with a larger sample size are needed to further elucidate this relationship

Comparison of Mortality and Therapy in Community Acquired Pneumonia

Background: Community associated pneumonia (CAP) is one the most common causes of hospital admissions, exceeding more than one million per year in the United States, contributing to 3.4% of inpatient mortality. Our objective was to compare 30-day mortality using therapies recommended for treatment of CAP. Methods: A multicenter retrospective analysis from four different hospitals was assessed from 2008 to 2013. The data was obtained from electronic medical records which included more than 70,000 patients. CAP patients were identified using discharge diagnostic codes during the years 2008-2013, as well as receiving therapy with ceftriaxone and azithromycin or a respiratory fluoroquinolone. Demographic data, antibiotic therapy, and Charlson comorbidity score was obtained to compare the study groups. Results: A total of 21,800 patients met the inclusion criteria for CAP. 1,740 patients were excluded as they received both beta-lactams and fluoroquinolones. The study included 20,600 patients. 11,201 patients (55.84%) received ceftriaxone with azithromycin, and 8,859 (44.16%) received fluoroquinolone therapy. The mortality rate for patients who received fluoroquinolone therapy was lower compared to the patients who received ceftriaxone plus azithromycin (3.56% vs 6.71%, p-value \u3c0.001). Conclusion: Our study showed statistically significant lower 30-day mortality using fluoroquinolone therapy compared to ceftriaxone plus azithromycin for treatment of CAP. Prospective blinded randomized control trials would be needed to support this evidence

Racial Differences in the Use of Adjuvant Chemotherapy for Breast Cancer in a Large Urban Integrated Health System

Background. Racial differences in breast cancer survival may be in part due to variation in patterns of care. To better understand factors influencing survival disparities, we evaluated patterns of receipt of adjuvant chemotherapy among 2,234 women with invasive, nonmetastatic breast cancer treated at the Henry Ford Health System (HFHS) from 1996 through 2005. Methods. Sociodemographic and clinical information were obtained from linked datasets from the HFHS, Metropolitan Detroit Cancer Surveillance Systems, and U.S. Census. Comorbidity was measured using the Charlson comorbidity index (CCI), and economic deprivation was categorized using a neighborhood deprivation index. Results. African American (AA) women were more likely than whites to have advanced tumors with more aggressive clinical features, to have more comorbidity and to be socioeconomically deprived. While in the unadjusted model, AAs were more likely to receive chemotherapy (odds ratio (OR) 1.22, 95% confidence interval (CI) 1.02–1.46) and to have a delay in receipt of chemotherapy beyond 60 days (OR 1.68, 95% CI, 1.26–1.48), after multivariable adjustment there were no racial differences in receipt (odds ratio (OR) 1.02, 95% confidence interval (CI) 0.73–1.43), or timing of chemotherapy (OR 1.18, 95 CI, 0.8–1.74). Conclusions. Societal factors and not race appear to have an impact on treatment delay among African American women with early breast cancer

Transfusion burden in non-dialysis chronic kidney disease patients with persistent anemia treated in routine clinical practice: a retrospective observational study

Background: Transfusion patterns are not well characterized in non-dialysis (ND) chronic kidney disease (CKD) patients. This study describes the proportion of patients transfused, units of blood transfused and trigger-hemoglobin (Hb) levels for transfusions in severe anemic, ND-CKD patients in routine practice. Methods. A retrospective cohort study of electronic medical record data from the Henry Ford Health identified 374 adult, ND-CKD patients with severe anemia (Hb \u3c 10 g/dL and subsequent use of erythropoiesis-stimulating agents [ESA] therapy, blood transfusions, or a second Hb \u3c 10 g/dL) between January 2004 and June 2008. Exclusions included those with prior diagnoses of cancer, renal or liver transplant, end-stage renal disease, acute bleeding, trauma, sickle cell disease, or aplastic anemia. A gap of ≥1 days between units of blood transfused was counted as a separate transfusion. Results: At least 1 transfusion (mean of 2 units; range, 1-4) was administered to 20% (75/374) of ND-CKD patients with mean (±SD) follow-up of 459 (±427) days. The mean (±SD) Hb level closest and prior to a transfusion was 8.8 (±1.5) g/dL. Patients who were hospitalized in the 6 months prior to their first anemia diagnosis were 6.3 times more likely to receive a blood transfusion than patients who were not hospitalized (p \u3c 0.0001). Patients with peripheral vascular disease (PVD) were twice as likely to have a transfusion as patients without PVD (p = 0.04). Conclusions: Transfusions were prevalent and the trigger hemoglobin concentration was approximately 9 g/dL among ND-CKD patients with anemia. To reduce the transfusion burden, clinicians should consider other anemia treatments including ESA therapy. © 2012 Fox et al; licensee BioMed Central Ltd

The occurrence of hyponatremia and its importance as a prognostic factor in a cross-section of cancer patients

BACKGROUND: Hyponatremia is prognostic of higher mortality in some cancers but has not been well studied in others. We used a longitudinal design to determine the incidence and prognostic importance of euvolemic and hypervolemic hyponatremia in patients following diagnosis with lymphoma, breast (BC), colorectal (CRC), small cell lung (SCLC), or non-small cell lung cancer (NSCLC). METHODS: Medical record and tumor registry data from two large integrated delivery networks were combined for patients diagnosed with lymphoma, BC, CRC, or lung cancers (2002-2010) who had ≥1 administration of radiation/chemotherapy within 6 months of diagnosis and no evidence of hypovolemic hyponatremia. Hyponatremia incidence was measured per 1000 person-years (PY). Cox proportional hazard models assessed the prognostic value of hyponatremia as a time-varying covariate on overall survival (OS) and progression-free survival (PFS). RESULTS: Hyponatremia incidence (%, rate) was 76 % each, 1193 and 2311 per 1000 PY, among NSCLC and SCLC patients, respectively; 37 %, 169 in BC; 64 %, 637 in CRC, and 60 %, 395 in lymphoma. Hyponatremia was negatively associated with OS in BC (HR 3.7; P = \u3c.01), CRC (HR 2.4; P \u3c .01), lung cancer (HR 2.4; P \u3c .01), and lymphoma (HR 4.5; P \u3c .01). Hyponatremia was marginally associated with shorter PFS (HR 1.3, P = .07) across cancer types. CONCLUSIONS: The incidence of hyponatremia is higher than previously reported in lung cancer, is high in lymphoma, BC, and CRC and is a negative prognostic indicator for survival. Hyponatremia incidence in malignancy may be underestimated. The effects of hyponatremia correction on survival in cancer patients require further study

Management of hepatocellular carcinoma from diagnosis in routine clinical practice

AIM: To assess real-world management of patients diagnosed with hepatocellular carcinoma (HCC) within an integrated delivery network. MATERIALS & METHODS: A retrospective cohort analysis of adults newly diagnosed with HCC from January 2014 to March 2019. Overall survival and treatment journey were assessed over the entire available follow-up period per patient. RESULTS: Of the 462 patients, 85% had ≥1 treatment. The 24-month overall survival rate (95% CI) from first treatment was 77% (72-82%). Majority of Child-Pugh class A (71%) and B (60%) patients received locoregional therapy first. Half (53.6%) of the patients with liver transplantation first were Child-Pugh class C patients. Sorafenib was the predominant systemic therapy. CONCLUSION: This integrated delivery network data analysis offers a comprehensive insight into the real-world management of HCC

Impact of Electronic Chronic Pain Questions on patient-reported outcomes and healthcare utilization, and attitudes toward eCPQ use among patients and physicians: prospective pragmatic study in a US general practice setting

OBJECTIVE: The Electronic Chronic Pain Questions (eCPQ) has been developed to help healthcare providers systematically capture chronic pain data. This study evaluated the impact of using the eCPQ on patient-reported outcomes (PROs) and healthcare resource utilization (HCRU) in a primary care setting, and patient and physician perceptions regarding use of, and satisfaction with, the eCPQ. METHODS: This was a prospective pragmatic study conducted at the Internal Medicine clinic within the Henry Ford Health (HFH) Detroit campus between June 2017 and April 2020. Patients (aged ≥18 years) attending the clinic for chronic pain were allocated to an Intervention Group to complete the eCPQ in addition to regular care, or a control group to receive regular care only. The Patient Health Questionnaire-2 and a Patient Global Assessment were assessed at baseline, 6-months, and 12-months study visits. HCRU data were extracted from the HFH database. Telephone qualitative interviews were conducted with randomly selected patients and physicians who used the eCPQ. RESULTS: Two hundred patients were enrolled, 79 in each treatment group completed all 3 study visits. No significant differences (p \u3e 0.05) were found in PROs and HCRU between the 2 groups. In qualitative interviews, physicians and patients reported the eCPQ as useful, and using the eCPQ improved patient-clinician interactions. CONCLUSION: Adding the eCPQ to regular care for patients with chronic pain did not significantly impact the PROs assessed in this study. However, qualitative interviews suggested that the eCPQ was a well-accepted and potentially useful tool from a patient and physician perspective. By using the eCPQ, patients were better prepared when they attended a primary care visit for their chronic pain and the quality of patient-physician communication was increased

Should Patients on Metformin Be Screened for Vit B12 Deficiency, and if so When?

Background: Metformin and its ability to cause vitamin B12 deficiency has been thoroughly studied and documented. Despite this, there is no formal screening recommendation. Our study investigates: whether there is a benefit to a formal screening guideline and, if so, when is it appropriate to screen for vitamin B12 deficiency in patients on Metformin. We additionally investigated quantifying if vitamin B12 testing is completed.Methods:We conducted a retrospective cohort study on a population of HAP patients who were ever tested for Vitamin B12 deficiency. Our exposed group was comprised of patients who had filled at least two prescriptions of Metformin between 1/1/2010 to 10/1/2016. Our unexposed group was not exposed to Metformin. Patients were followed through 12/31/2018 for vitamin B12 testing and deficiency. Results:Amongst our exposed population of 13489 patients, 44.86% of patients were tested for Vitamin B12 deficiency. Average time to test was 990 days, the average time to test positive was 1831 days. Factors associated with testing for B12 deficiency were male gender (41.5%), older age (62.79% in patients over 80 years old), Caucasian race (48.98%), and malabsorption syndromes (71.7%) including bariatric surgery, celiac disease, small bowel disease, and PPI use. Amongst tested patients in the exposed population, it was found that 3.34% had vitamin B12 deficiency. The only factor associated with deficiency in a multivariable analysis was older age. African American ethnicity approached significance as a protective factor. Discussion: While we found testing to be suboptimal, vitamin B12 deficiency incidence was lower than expected. On chart review it was found that reasons for testing for B12 level included anemia, cognitive decline, and neuropathy. This implies that patients were having symptoms of deficiency leading to testing. Our study found that 3.34% of patients exposed to Metformin had vitamin B12 deficiency. Of patients not exposed to Metformin, 2.14% were found to have deficiency.https://scholarlycommons.henryford.com/merf2019basicsci/1000/thumbnail.jp

Real-world impact of fremanezumab on migraine symptoms and resource utilization in the United States

BACKGROUND: Fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), is approved for migraine prevention in adults. Real-world data on the effectiveness of fremanezumab are limited. This retrospective, observational cohort study assessed patient-reported migraine symptoms, health care resource utilization (HCRU), and direct medical costs before and after fremanezumab treatment initiation. METHODS: Data were extracted from September 2018 through June 2020 from the Midwest component of EMRClaims+®, an integrated health services database containing \u3e 20 million medical records from national commercial insurance claims, Medicare claims, and regional electronic medical records. Patients included in the cohort analysis were aged ≥ 18 years and were administered fremanezumab, with enrollment or treatment history for ≥ 6 months prior (pre-index) to initiating fremanezumab (index date) and ≥ 1 month after the index date (post-index), and without pregnancy or pregnancy-related encounters during the study period. Patient-reported headache frequency, migraine pain intensity (MPI), composite migraine symptoms, and HCRU were assessed pre-index and ≥ 1 month after fremanezumab initiation. Wilcoxon signed-rank tests were used to compare means of migraine symptoms and outcomes and HCRU before and after fremanezumab initiation. RESULTS: Overall, 172 patients were eligible for analysis. Of patients who self-reported (n = 129), 83.7% reported improvement in headache frequency or symptoms after fremanezumab treatment. Specifically, headache frequency decreased by 63% after fremanezumab initiation: mean (standard deviation) headache frequency was 22.24 (9.29) days per month pre-index versus 8.24 (7.42) days per month post-index (P \u3c 0.0001). Mean MPI also decreased by 18% after fremanezumab initiation: MPI was 5.47 (3.19) pre-index versus 4.51 (3.34) post-index (P = 0.014). Mean emergency room (ER) visits per month decreased from 0.72 to 0.54 (P = 0.003), and mean outpatient visits per month decreased from 1.04 to 0.81 (P \u3c 0.001). Mean hospitalizations per month decreased, but the results did not reach statistical significance (P = 0.095). Hospitalization and ER costs decreased, while outpatient costs increased, from pre-index to post-index, but differences were not statistically significant (P ≥ 0.232). CONCLUSIONS: Significant reductions in headache frequency, MPI, and HCRU were observed after fremanezumab initiation in patients with migraine in a US real-world setting
