Introduction: Opioids and benzodiazepines are commonly prescribed for cancer symptoms. In combination, they can increase the risk of adverse events, particularly for older adults with multimorbidity, who represent most patients with cancer. We aimed to understand cancer care providers' practices for opioid and benzodiazepine coprescribing and mitigating potential harms.

Background: While nearly 50% of adult women report at least one episode of urinary incontinence (UI), most never receive treatment.

Objective: To better integrate primary and specialty UI care, we conducted (i) an environmental scan to assess the availability of key pathway resources in primary care, (ii) interviews with primary care providers to understand barriers to care, and (iii) a pilot UI care pathway intervention.

Methods: Environmental scan: Clinic managers from all primary care clinics within a Midwestern healthcare system were invited to participate in an interview covering the availability of clinic resources.

Background: Because the markups on cancer drugs vary by payor, providers' financial incentive to use high-price drugs is differential according to each patient's insurance type. We evaluated the association between patient insurer (commercial vs Medicaid) and the use of high-priced cancer treatments.

Materials And Methods: We linked cancer registry, administrative claims, and demographic data for individuals diagnosed with cancer in North Carolina from 2004 to 2011, with either commercial or Medicaid insurance.

Article Synopsis
  • The study assesses the cost-effectiveness of gene therapy for sickle cell disease (SCD) and its value-based pricing, focusing on its economic impact in the U.S. and the African heritage community.
  • Two independent simulation models were used to analyze the cost-effectiveness, leading to different incremental cost-effectiveness ratios (ICERs) based on factors like population and quality-of-life effects.
  • The analysis found that at a gene therapy price of $2 million, ICERs ranged from $126,000 to $427,000 per Quality-Adjusted Life Year (QALY), with value-based prices deemed acceptable between $1 million and $2.5 million, depending on methodology

Purpose: Cancer is a major reason for concurrent prescription of opioids with other sedating medications-particularly benzodiazepines and gabapentinoids-yet population-based assessments of the extent and predictors of concurrent prescribing among clinically and demographically diverse patients with cancer are lacking.

Methods: We conducted a retrospective cohort study of patients with non-metastatic cancer using North Carolina cancer registry data linked with Medicare and private insurance claims (2013-2016). We used modified Poisson regression to assess associations of patient characteristic with adjusted relative risk (aRR) of new concurrent prescribing of opioids with benzodiazepines or gabapentinoids after diagnosis.

Background: Guidelines recommend sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP1) receptor agonists as second-line therapy for patients with type 2 diabetes. Expanding their use as first-line therapy has been proposed but the clinical benefits may not outweigh their costs.

Objective: To evaluate the lifetime cost-effectiveness of a strategy of first-line SGLT2 inhibitors or GLP1 receptor agonists.

Objective: Given persistent racial/ethnic differences in type 2 diabetes outcomes and the lasting benefits conferred by early glycemic control, we examined racial/ethnic differences in diabetes medication initiation during the year following diagnosis.

Methods: Among adults newly diagnosed with type 2 diabetes (2005-2016), we examined how glucose-lowering medication initiation differed by race/ethnicity during the year following diagnosis. We specified modified Poisson regression models to estimate the association between race/ethnicity and medication initiation in the entire cohort and within subpopulations defined by HbA1c, BMI, age at diagnosis, comorbidity, and neighborhood deprivation index (a census tract-level socioeconomic indicator).

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2Is) are a recent class of medication approved for the treatment of type 2 diabetes (T2D). Previous meta-analyses have quantified the benefits and harms of SGLT2Is; however, these analyses have been limited to specific outcomes and comparisons and included trials of short duration. We comprehensively reviewed the longer-term benefits and harms of SGLT2Is compared to placebo or other anti-hyperglycemic medications.

Importance: By 2020, nearly all states had adopted oncology parity laws in the US, ensuring that patients in fully insured private health plans pay no more for orally administered anticancer medications (OAMs) than infused therapies. Between 2013 and mid-2017, 11 states implemented parity with out-of-pocket spending caps, which may further reduce patient out-of-pocket spending.

Objective: To compare OAM uptake and out-of-pocket and health plan spending on OAMs in states with parity with and without spending caps, as well as to assess out-of-pocket spending for caps that apply predeductible vs postdeductible.

Article Synopsis
  • The study investigated the financial relationships oncologists have with pharmaceutical companies, specifically whether those involved in clinical practice guideline committees receive more industry payments compared to those who do not.
  • Researchers analyzed data from a case-control study involving oncologists on National Comprehensive Cancer Network (NCCN) committees to compare payments received before and after joining the committee.
  • Results showed that oncologists who joined these committees received significantly higher payments before joining, but their financial ties did not increase post-appointment, raising concerns about potential conflicts of interest in clinical guidelines.
