Pharmacologic and Nonpharmacologic Treatments for Posttraumatic Stress Disorder: An Update of the PTSD-Repository Evidence Base

Author/s: 
Agency for Healthcare Research and Quality

Structured Abstract

Objectives. Identify and abstract data from posttraumatic stress disorder (PTSD) treatment randomized controlled trials (RCTs) to update the PTSD Trials Standardized Data Repository (PTSD-Repository) with data on PTSD and mental health, including suicide-related outcomes and substance use.

Data sources. We searched PTSDpubs, Ovid® MEDLINE®, Cochrane CENTRAL, PsycINFO®, Embase®, CINAHL®, and Scopus® for eligible RCTs published from 1980 to May 22, 2020.

Review methods. In consultation with the National Center for PTSD (NCPTSD), we updated the PTSD-Repository by expanding inclusion criteria to RCTs targeting comorbid PTSD/substance use disorder (SUD) and adding data elements. The primary publication for each RCT was abstracted; data and citations from secondary publications (i.e., companion papers) appear in the same record. We assessed risk of bias (ROB) for all studies in the PTSD-Repository. We undertook an exploratory assessment of an expanded ROB system developed with guidance from a Technical Expert Panel and NCPTSD, which was pilot tested on a small subset of studies.

Results. We identified 47 new RCTs of interventions for PTSD and 21 RCTs for comorbid PTSD/SUD, resulting in 389 included studies published from 1988 to 2020. Psychotherapy interventions were the most common (63%), followed by pharmacologic interventions (25%). Most studies were conducted in the United States (62%) and had sample sizes ranging from 25 to 99 participants (60%). Approximately half of studies enrolled community participants (55%), and most were conducted in the outpatient setting (72%). Studies typically enrolled participants with a mix of trauma types (53%). Most RCTs (60%) were rated as having a medium ROB, and only 6 percent were rated as having a low ROB. Our pilot testing of an expanded ROB assessment tool emphasized more detailed assessment of elements, including: (1) methods for managing missing data, including both dropout from treatment and missing measurements (i.e., loss to followup); (2) differential assessment of subjective and objective outcomes; and (3) consideration of a five-category overall rating system.

Conclusions. The PTSD-Repository is a comprehensive database of data from PTSD trials. The PTSD-Repository allows clinical, research, education, and policy stakeholders to understand current research on treatment effectiveness and harms, and enable informed decisions about future research, mental health policy, and clinical care priorities. This report updates the studies and variables included in the PTSD-Repository to include recently published trials, interventions targeting comorbid PTSD/SUD, variables related to comorbidities such as suicide and SUDs, and ROB assessment.

Use of 13-Valent Pneumococcal Conjugate Vaccine and 23-Valent Pneumococcal Polysaccharide Vaccine Among Adults Aged ≥65 Years: Updated Recommendations of the Advisory Committee on Immunization Practices

Two pneumococcal vaccines are currently licensed for use in adults in the United States: a 13-valent pneumococcal conjugate vaccine (PCV13 [Prevnar 13, Pfizer, Inc.]) and a 23-valent pneumococcal polysaccharide vaccine (PPSV23 [Pneumovax 23, Merck and Co., Inc.]). In 2014, the Advisory Committee on Immunization Practices (ACIP)* recommended routine use of PCV13 in series with PPSV23 for all adults aged ≥65 years based on demonstrated PCV13 safety and efficacy against PCV13-type pneumonia among adults aged ≥65 years (1). At that time, ACIP recognized that there would be a need to reevaluate this recommendation because it was anticipated that PCV13 use in children would continue to reduce disease burden among adults through reduced carriage and transmission of vaccine serotypes from vaccinated children (i.e., PCV13 indirect effects). On June 26, 2019, after having reviewed the evidence accrued during the preceding 3 years (https://www.cdc.gov/vaccines/acip/recs/grade/PCV13.html), ACIP voted to remove the recommendation for routine PCV13 use among adults aged ≥65 years and to recommend administration of PCV13 based on shared clinical decision-making for adults aged ≥65 years who do not have an immunocompromising condition,† cerebrospinal fluid (CSF) leak, or cochlear implant, and who have not previously received PCV13. ACIP recognized that some adults aged ≥65 years are potentially at increased risk for exposure to PCV13 serotypes, such as persons residing in nursing homes or other long-term care facilities and persons residing in settings with low pediatric PCV13 uptake or traveling to settings with no pediatric PCV13 program, and might attain higher than average benefit from PCV13 vaccination. When patients and vaccine providers§ engage in shared clinical decision-making for PCV13 use to determine whether PCV13 is right for a particular person, considerations might include both the person's risk for exposure to PCV13 serotypes and their risk for developing pneumococcal disease as a result of underlying medical conditions. All adults aged ≥65 years should continue to receive 1 dose of PPSV23. If the decision is made to administer PCV13, it should be given at least 1 year before PPSV23. ACIP continues to recommend PCV13 in series with PPSV23 for adults aged ≥19 years with an immunocompromising condition, CSF leak, or cochlear implant (2).
