Background: During the COVID-19 pandemic, use of telemedicine (TM) increased dramatically, but it is unclear how use varies by characteristics of people with Alzheimer's disease (AD), multiple sclerosis (MS), or Parkinson's disease (PD).

Methods: This cross-sectional study used US PharMetrics Plus commercial claims data from January 1, 2019, to December 31, 2021. TM use (≥1 Current Procedural Terminology code) was assessed in each study year (2019, 2020, and 2021) among people with ≥1 inpatient or ≥2 outpatient diagnosis codes ≥30 days apart for AD, MS, or PD.

Article Synopsis
  • Patients with opioid use disorder (OUD) often utilize emergency services and hospitals more, and the PROUD trial aimed to see if office-based addiction treatment (OBAT) could help reduce this.
  • The trial involved 12 clinics and focused on OUD patients, comparing outcomes between those receiving OBAT and usual care over two years after treatment began.
  • Results showed that, despite increased treatment days for intervention patients, there was no significant difference in emergency or hospital utilization between the OBAT and usual care groups for both pre- and post-randomization patients.

Importance: Few primary care (PC) practices treat patients with medications for opioid use disorder (OUD) despite availability of effective treatments.

Objective: To assess whether implementation of the Massachusetts model of nurse care management for OUD in PC increases OUD treatment with buprenorphine or extended-release injectable naltrexone and secondarily decreases acute care utilization.

Design, Setting, And Participants: The Primary Care Opioid Use Disorders Treatment (PROUD) trial was a mixed-methods, implementation-effectiveness cluster randomized clinical trial conducted in 6 diverse health systems across 5 US states (New York, Florida, Michigan, Texas, and Washington).

Because long-term opioid therapy (LtOT) for chronic pain has uncertain benefits and dose-dependent harms, safe and effective strategies for opioid tapering are needed. Adapting a promising pilot study intervention, we conducted the STRategies to Improve Pain and Enjoy life (STRIPE) pragmatic clinical trial. Patients in integrated health system on moderate-to-high dose of LtOT for chronic noncancer pain were randomized individually to usual care plus intervention (n = 79) or usual care only (n = 74).

Background: While many studies have assessed and measured patient attitudes toward deprescribing, less quantitative research has addressed the provider perspective. We thus sought to describe provider knowledge, beliefs, and self-efficacy to deprescribe, with a focus on opioids and sedative-hypnotics.

Methods: An electronic anonymous survey was distributed to primary care providers at Kaiser Permanente Washington.

Background: Cancer survivors receive more long-term opioid therapy (LTOT) than people without cancer, but the safety of LTOT prescribing is unknown.

Methods: Opioid-naive adults aged ≥66 years who had been diagnosed in 2008-2015 with breast, lung, head and neck, or colorectal cancer were identified with data from Surveillance, Epidemiology, and End Results cancer registries linked with Medicare claims. Survivors with 1 or more LTOT episodes (≥90 consecutive days) occurring ≥1 year after their cancer diagnosis and before censoring at hospice entry, another cancer diagnosis, 6 months before death, or December 2016 were included.

High-dose, long-term opioid therapy (LtOT) is associated with risk for serious harms. Rapid opioid discontinuation may lead to increased pain, psychological distress, and illicit opioid use, but gradual, supported opioid taper may reduce these risks. We previously demonstrated that an opioid taper support and pain coping skills training intervention reduced opioid dose more than usual care (43% vs 19% dose reduction from baseline), with no increase in pain intensity and a significant reduction in activity interference.

Article Synopsis
  • - The PROUD trial aims to test a collaborative care model in primary care settings to improve treatment access and outcomes for individuals with opioid use disorder (OUD), focusing on increasing medication days and reducing acute healthcare use.
  • - The study involves a hybrid design in six healthcare systems, where two primary care clinics are randomized to either the intervention (with a nurse care manager and DEA-waivered providers) or usual care, targeting patients aged 16-90 over a span of five years.
  • - Data collection combines quantitative measures from electronic health records and administrative data with qualitative insights from staff surveys and site observations to understand barriers and facilitators to the implementation of OUD treatment.

Background: Certain medications may increase the risk of death or death from specific causes (eg, sudden cardiac death), but these risks may not be identified in premarket randomized trials. Having the capacity to examine death in postmarket safety surveillance activities is important to the US Food and Drug Administration's (FDA) mission to protect public health. Distributed networks of electronic health plan databases used by the FDA to conduct multicenter research or medical product safety surveillance studies often do not systematically include death or cause-of-death information.

Background: Primary care providers prescribe most long-term opioid therapy and are increasingly asked to taper the opioid doses of these patients to safer levels. A recent systematic review suggests that multiple interventions may facilitate opioid taper, but many of these are not feasible within the usual primary care practice.

Objective: To determine if opioid taper plans documented by primary care providers in the electronic health record are associated with significant and sustained opioid dose reductions among patients on long-term opioid therapy.
