Clinical Impact of Accelerate Pheno Rapid Blood Culture Detection System in Bacteremic Patients.

BACKGROUND: Accelerate Pheno blood culture detection system (AXDX) provides rapid identification and antimicrobial susceptibility testing results. Limited data exist regarding its clinical impact. Other rapid platforms coupled with antimicrobial stewardship program (ASP) real-time notification (RTN) have shown improved length of stay (LOS) in bacteremia. METHODS: A single-center, quasi-experimental study of bacteremic inpatients before and after AXDX implementation was conducted comparing clinical outcomes from 1 historical and 2 intervention cohorts (AXDX and AXDX + RTN). RESULTS: Of 830 bacteremic episodes, 188 of 245 (77%) historical and 308 (155 AXDX, 153 AXDX + RTN) of 585 (65%) intervention episodes were included. Median LOS was shorter with AXDX (6.3 days) and AXDX + RTN (6.7 days) compared to historical (8.1 days) (P = .001). In the AXDX and AXDX + RTN cohorts, achievement of optimal therapy (AOT) was more frequent (93.6% and 95.4%, respectively) and median time to optimal therapy (TTOT) was faster (1.3 days and 1.4 days, respectively) compared to historical (84.6%, P ≤ .001 and 2.4 days, P ≤ .001, respectively). Median antimicrobial days of therapy (DOT) was shorter in both intervention arms compared to historical (6 days each vs 7 days; P = .011). Median LOS benefit during intervention was most pronounced in coagulase-negative Staphylococcus bacteremia (P = .003). CONCLUSIONS: LOS, AOT, TTOT, and total DOT significantly improved after AXDX implementation. Addition of RTN did not show further improvement over AXDX and an already active ASP. These results suggest that AXDX can be integrated into healthcare systems with an active ASP even without the resources to include RTN.

Impact of Medical Marijuana Legalization on Opioid Use, Chronic Opioid Use, and High-risk Opioid Use.

OBJECTIVE: To determine the association of medical marijuana legalization with prescription opioid utilization. METHODS: A 10% sample of a nationally representative database of commercially insured population was used to gather information on opioid use, chronic opioid use, and high-risk opioid use for the years 2006-2014. Adults with pharmacy and medical benefits for the entire calendar year were included in the population for that year. Multilevel logistic regression analysis, controlling for patient, person-year, and state-level factors, were used to determine the impact of medical marijuana legalization on the three opioid use measures. Sub-group analysis among cancer-free adults and cancer-free adults with at least one chronic non-cancer pain condition in the particular year were conducted. Alternate regression models were used to test the robustness of our results including a fixed effects model, an alternate definition for start date for medical marijuana legalization, a person-level analysis, and a falsification test. RESULTS: The final sample included a total of 4,840,562 persons translating into 15,705,562 person years. Medical marijuana legalization was found to be associated with a lower odds of any opioid use: OR = 0.95 (0.94-0.96), chronic opioid use: OR = 0.93 (0.91-0.95), and high-risk opioid use: OR = 0.96 (0.94-0.98). The findings were similar in both the sub-group analyses and all the sensitivity analyses. The falsification tests showed no association between medical marijuana legalization and prescriptions for antihyperlipidemics (OR = 1.00; CI 0.99-1.01) or antihypertensives (OR = 1.00; CI 0.99-1.01). CONCLUSIONS: In states where marijuana is available through medical channels, a modestly lower rate of opioid and high-risk opioid prescribing was observed. Policy makers could consider medical marijuana legalization as a tool that may modestly reduce chronic and high-risk opioid use. However, further research assessing risk versus benefits of medical marijuana legalization and head to head comparisons of marijuana versus opioids for pain management is required.

Association of the "CDC Guideline for Prescribing Opioids for Chronic Pain" With Emergency Department Opioid Prescribing.

BACKGROUND: The number of unintentional deaths due to prescription drug overdose has risen in recent years due to the increased utilization of opioid analgesics. Pain is one of the most common reasons for patients to visit an emergency department (ED) and is often treated with opioid analgesics. In 2016, the Centers for Disease Control and Prevention (CDC) released guidelines for primary care providers on prescribing opioids for chronic pain. OBJECTIVES: The objective of this study was to determine if release of the 2016 CDC guidelines for prescribing opioids for chronic pain was associated with changes in prescribing habits in the ED of an academic medical center. METHODS: The data were extracted from patient electronic health records between January 2015 and June 2017. The primary endpoint of the study was average morphine equivalent daily dose (MEDD) for the pre- and postguideline cohorts. RESULTS: A total of 8652 patients were included in the analysis (4389 in the preguideline cohort and 4263 in the postguideline cohort). The average MEDD decreased significantly from 30.6 ± 20.2 MEDD in the preguideline cohort to 29.8 ± 19.5 MEDD in the postguideline cohort (p = 0.0460). There was also a significant decrease in the rate of concomitant opioid and benzodiazepine prescribing as well as average days' supply per prescription in the postguideline cohort, as compared with the preguideline cohort. CONCLUSIONS: The average MEDD prescribed in the ED of an academic medical center decreased after the release of the CDC guidelines on opioid prescribing for chronic pain.

The Cost-Effectiveness of an Advanced Hybrid Closed-Loop System Compared to Standard Management of Type 1 Diabetes in a Singapore Setting.

Background: Despite advances in technology, glycemic outcomes in people with type 1 diabetes (T1D) remain suboptimal. The MiniMed 780G (MM780G) advanced hybrid closed-loop (AHCL) system is the latest technology for T1D management with established safety and efficacy. This study explores the cost-effectiveness of MM780G AHCL compared against multiple daily injections (MDI) plus intermittently scanned continuous glucose monitor (isCGM). Methods: A cost-utility analysis was conducted, simulating lifetime outcomes for 1000 T1D individuals, with baseline hemoglobin A1c of 8.4%, using the IQVIA Core Diabetes Model (CDM) v9.5. A Singapore health care payer perspective was taken with 2023 costs applied. Treatment effects were taken from the ADAPT study and treatment-related events from a combination of sources. T1D complication costs were derived from local literature, and health state utilities and disutilities from published literature. Scenario analyses and probabilistic sensitivity analyses (PSAs) explored uncertainty. Cost-effectiveness was assessed based on willingness-to-pay (WTP) thresholds set to Singapore Dollars (SGD) 45,000 (United States Dollars [USD] 33,087) per quality-adjusted life year (QALY) and Singapore's gross domestic product (GDP) per capita of SGD 114,165 (USD 83,941) per QALY. Results: A switch from MDI plus isCGM to MM780G resulted in expected gains in life-years (+0.78) and QALYs (+1.45). Cost savings through reduction in T1D complications (SGD 25,465; USD 18,723) partially offset the higher treatment costs in the AHCL arm (+SGD 74,538; +USD 54,805), resulting in an estimated incremental cost-effectiveness ratio of SGD 33,797 (USD 24,850) per QALY gained. Findings were robust, with PSA outputs indicating 81% and 99% probabilities of cost-effectiveness at the stated WTP thresholds. Conclusion: MM780G is a cost-effective option for people with T1D managed in a Singapore setting.

Depression and diabetes distress in patients with diabetes.

We aimed to identify the prevalence of comorbid depression, diabetes, and diabetes distress and assess glycemic control and rates of diabetes-related complications. While the presence of either depression or distress did not predict the level of glycemic control, certain macro- and microvascular complications were more prevalent with depression.

The Impact of Continuous Infusion Compared to Intravenous Bolus Administration of Pantoprazole on Length of Intensive Care Unit Stay in Critically Ill Patients.

Purpose: To determine if intravenous (IV) bolus pantoprazole increases intensive care unit (ICU) length of stay compared to IV infusion pantoprazole for treatment of gastrointestinal (GI) bleeding in critically ill patients. Methods: This retrospective cohort study included adult patients admitted to the ICU with GI bleeds. Patients treated with IV pantoprazole from January 1, 2017 to December 31, 2017 were analyzed in the continuous infusion group, and patients treated from March 1, 2018 to February 28, 2019 were analyzed in the bolus only group. Patients with pregnancy, variceal bleeds, or lower GI bleeds were excluded. Intensive care unit length of stay was compared between the two cohorts using the Mann Whitney U test. Adjusted analysis was conducted using the generalized linear model with gamma log link to estimate the effect of type of infusion on ICU length of stay. Results: A total of 145 patients were included in the analysis, with 72 patients in the continuous infusion group and 73 patients in the bolus only group. The median ICU length of stay was 70.5 hours for continuous infusion and 64 hours for bolus only pantoprazole (P-value = .577). In the adjusted analysis, there was no difference in ICU length of stay between the continuous infusion and bolus only groups (RR, 1.06; 95% CI, .76-1.47). Conclusion: Intensive care unit length of stay was not prolonged with the use of IV bolus only compared to continuous infusion pantoprazole. Intravenous bolus only pantoprazole may be used in critically ill patients for treatment of upper GI bleeding.

Healthcare costs and utilization associated with pain among breast cancer survivors: a propensity score matched cohort study using SEER-Medicare data.

PURPOSE: To assess healthcare costs and utilization of treatment-related pain among breast cancer survivors. METHODS: A retrospective matched cohort study using Surveillance Epidemiology and End Results SEER-Medicare linked data was conducted. The study population included older breast cancer survivors continuously enrolled in Medicare parts A, B, and D in the baseline and 1-year follow-up periods. Survivors with pain were matched to survivors without pain using PSM. Incremental all-cause healthcare costs associated with pain were calculated using a two-part model. Incremental healthcare utilization of inpatient hospitalizations, ER, outpatient, and physician services were estimated using the negative binomial model. RESULTS: The study included 101,120 non-metastatic breast cancer patients between July 2007 and September 2013. The final analytical cohort after matching included 5891 survivors in both groups. The incremental annual all-cause total healthcare costs per patient were higher in survivors with pain as compared to survivors without pain (Δ = 4379.00 (95% CI: 4308.00-4448.80). The main cost drivers were hospitalizations at 71%, followed by ER at 16% and physician services at 9% for survivors diagnosed with pain. Annual all-cause healthcare resource utilization was also found to be higher in survivors with pain as compared to survivors without pain across all categories of use. Similar trends were observed when stratified by surgery type and subgrouped by pain type and pain-related costs. CONCLUSION: This study provided baseline data that can be used for future cost-effectiveness analysis studies and burden of illness studies. IMPLICATION FOR CANCER SURVIVORS: Treatment-related costs have a substantial burden on healthcare costs and the utilization of Medicare.

The use of gabapentinoids and opioids and risk of developing opioid-induced respiratory depression among older breast cancer survivors with neuropathic pain.

PURPOSE: To estimate the combined effect of gabapentinoid and opioid therapy compared to opioid monotherapy on the risk of developing opioid-induced respiratory depression among breast cancer survivors with neuropathic pain. METHOD: A nested case-control study of Medicare female breast cancer survivors with neuropathic pain receiving both opioids and gabapentinoids, opioid monotherapy, gabapentinoid monotherapy, and none of these drugs was conducted using SEER-Medicare between 2007 and 2015. Cases were survivors with respiratory depression and were matched with controls on the event date (± 1 year), age at diagnosis (± 5 years), and stage at diagnosis. Exposure to opioids and gabapentinoids was assessed 120 days before the event date. Conditional logistic regression was used to assess the impact of exposure among cases and controls. RESULTS: A total of 657 cases and 11,471 controls were identified. After matching, 656 cases and 5612 controls were retained, and cases were more likely to be diagnosed with mental health disorders (24.4% vs 10.5%, p < 0.0001) than controls. In the primary adjusted analysis, combined opioids and gabapentin use were associated with an increased risk of respiratory depression compared to opioid monotherapy (Adj. OR: 1.513; 95% CI: 1.473-2.350). Additionally, under secondary analysis, combined opioids and gabapentin use were associated with an increased risk of respiratory depression compared to receiving neither of these classes. (Adj. OR: 1.595; 95% CI: 1.050-2.421). CONCLUSION: There is a need for dose titration strategies of gabapentinoids and caution when co-prescribing opioids and gabapentinoids in older cancer survivors.

Factors Associated With Guideline-Concordant Pharmacological Treatment for Neuropathic Pain Among Breast Cancer Survivors.

PURPOSE: To identify factors associated with receiving guideline-concordant treatment among breast cancer survivors with neuropathic pain. MATERIALS AND METHODS: A retrospective case-control study was conducted using the SEER-Medicare linked database. We included female breast cancer survivors diagnosed with non-metastatic breast cancer (stages 0-III) between 2007 and 2015 who developed treatment-related neuropathic pain during their survivorship period. Guideline-concordant treatment was defined based on NCCN guidelines. Factors associated with receiving guideline-concordant treatment were assessed using multivariable logistic regression and backward selection was used to identify potential associated factors. RESULTS: Around 16.7% of breast cancer survivors in the study developed a neuropathic pain condition. The mean time to develop neuropathic pain was 1.4 years after beginning adjuvant treatment. On average, patients who developed neuropathic pain and received guideline-concordant treatment did so at 2.4 months after their neuropathic pain diagnosis. We found that survivors that are black and of other races were less likely to receive guideline-concordant treatment for breast cancer treatment-related neuropathic pain. Whereas survivors with diabetes, mental health disorders, hemiplegia, prior continuous opioid use, benzodiazepine use, nonbenzodiazepine CNS depressant use, or antipsychotic medication use were less likely to receive guideline-concordant treatment. CONCLUSION: This study suggests that minority races, prior medication use, and comorbid conditions are associated with guideline-concordant treatment among breast cancer survivors with neuropathic pain. These findings warrant attention towards minority races to prescribe them guideline-concordant treatment as well as caution when prescribing concurrent pain medications to survivors with comorbidities and prior medication use.

Risk factors and clinical outcomes associated with blood culture contamination.

OBJECTIVE: To determine patient-specific risk factors and clinical outcomes associated with contaminated blood cultures. DESIGN: A single-center, retrospective case-control risk factor and clinical outcome analysis performed on inpatients with blood cultures collected in the emergency department, 2014-2018. Patients with contaminated blood cultures (cases) were compared to patients with negative blood cultures (controls). SETTING: A 509-bed tertiary-care university hospital. METHODS: Risk factors independently associated with blood-culture contamination were determined using multivariable logistic regression. The impacts of contamination on clinical outcomes were assessed using linear regression, logistic regression, and generalized linear model with γ log link. RESULTS: Of 13,782 blood cultures, 1,504 (10.9%) true positives were excluded, leaving 1,012 (7.3%) cases and 11,266 (81.7%) controls. The following factors were independently associated with blood-culture contamination: increasing age (adjusted odds ratio [aOR], 1.01; 95% confidence interval [CI], 1.01-1.01), black race (aOR, 1.32; 95% CI, 1.15-1.51), increased body mass index (BMI; aOR, 1.01; 95% CI, 1.00-1.02), chronic obstructive pulmonary disease (aOR, 1.16; 95% CI, 1.02-1.33), paralysis (aOR 1.64; 95% CI, 1.26-2.14) and sepsis plus shock (aOR, 1.26; 95% CI, 1.07-1.49). After controlling for age, race, BMI, and sepsis, blood-culture contamination increased length of stay (LOS; ß = 1.24 ± 0.24; P < .0001), length of antibiotic treatment (LOT; ß = 1.01 ± 0.20; P < .001), hospital charges (ß = 0.22 ± 0.03; P < .0001), acute kidney injury (AKI; aOR, 1.60; 95% CI, 1.40-1.83), echocardiogram orders (aOR, 1.51; 95% CI, 1.30-1.75) and in-hospital mortality (aOR, 1.69; 95% CI, 1.31-2.16). CONCLUSIONS: These unique risk factors identify high-risk individuals for blood-culture contamination. After controlling for confounders, contamination significantly increased LOS, LOT, hospital charges, AKI, echocardiograms, and in-hospital mortality.

Impact of Hydroxyurea Starting Dose on Pain Outcomes in Patients with Sickle Cell Disease.

In patients with sickle cell disease, hydroxyurea decreases the number of pain crises experienced. This study aimed to evaluate the difference in pain outcomes between patients started on a guideline concordant, weight-based starting dose of at least 15 mg/kg/day of hydroxyurea and those not. The first prescription of hydroxyurea was the baseline date, follow-up was a visit 60-120 days after baseline. The primary outcome was the change in opioid prescribing between baseline and follow-up. 138 patients met inclusion criteria; of these, 55 were started on a guideline concordant dose of hydroxyurea. Greater white blood cell count (9.5 vs 12.0; p < 0.01) was statistically associated with subtherapeutic dosing. Greater actual body weight (68.0 vs 72.1 kg; p = 0.16) also appeared higher in the non-guideline concordant group. No statistically significant difference in opioid prescribing was observed between those started on a guideline concordant dose of hydroxyurea and those who were not. In the guideline concordant starting dose group, 42% had a reduction in pain scores at first follow up, compared to 35% with a non-guideline recommended starting dose. (p = 0.41). While this difference is in the direction that would be expected based on the guidelines, the difference does not appear to be clinically meaningful.

Calcium Channel Blockers and Risk of Lymphedema among Breast Cancer Patients: Nested Case-Control Study.

BACKGROUND: To assess the risk of lymphedema associated with the use of calcium channel blockers (CCB) among breast cancer patients. METHODS: A nested case-control study of adult female breast cancer patients receiving an antihypertensive agent was conducted using administrative claims data between 2007 and 2015. Cases were patients with lymphedema who were matched to 5 controls based on nest entry date (±180 days), age (±5 years), number of hypertensive drug classes, Charlson Comorbidity Index (CCI), thiazide exposure, and insurance type. Exposure to CCBs and covariates was identified in the 180-day period prior to event date. Conditional logistic regression was used to assess the impact of exposure among cases and controls. RESULTS: A total of 717 cases and 1,681 matched controls were identified. After matching on baseline characteristics, mastectomy (7.8% vs. 4.8%; P = 0.0039), exposure to radiotherapy (27.1% vs. 21.7%; P = 0.0046), taxane-based chemotherapy (11.7% vs. 7.4%; P = 0.0007), anthracycline-based chemotherapy (6.0% vs. 3.6%; P = 0.0073), CCB use (28.3% vs. 23.3%; P = 0.0087), and CCI (19.8% vs. 12.7%; P < 0.0001; score of 4 or above) were all higher in cases during the 180 days prior to the event date. In the adjusted analysis, CCB exposure was significantly associated with increased risk of lymphedema (OR = 1.320; 95% confidence interval, 1.003-1.737). CONCLUSIONS: CCB use was significantly associated with the development of lymphedema in breast cancer patients. IMPACT: CCBs should be avoided or used with caution in breast cancer patients to reduce the risk for developing lymphedema.
