Aromatherapy and Essential Oils

Background/Objectives of Review

The evidence map will be used by the Integrative Health Coordinating Center, Patient-Centered Care & Cultural Transformation, and Pharmacy Benefits Management Services to determine the evidence base for providing aromatherapy to Veterans to support Veteran health and to inform future research and identify gaps in practice.

Key Questions

What evidence is available on the effectiveness of aromatherapy or essential oils for health-related conditions?

PICOTS

Population(s): Adults (18+), including pregnant and postpartum women, receiving an intervention of interest. Children and adolescents are excluded.

Interventions: Include: Essential oil preparations that are inhaled, topically applied, or oral rinses that do not contain alcohol or other antiseptic ingredients.

Exclude: Essential oil preparations that are ingested or consumed; preparations where essential oils are combined with another drug or active ingredient; preparations intended for mucosal absorption in areas other than nasal/oral (eg, enema); oral rinses that contain antiseptic ingredients, such as Listerine containing 27% alcohol.

Comparator: Any

Outcome(s): Primary symptoms

Secondary outcomes (anxiety, depression, or mental health outcomes that are not primary to a diagnosis; sleep; etc)

Global health outcomes (eg, quality of life, activities of daily living, mobility, social functioning, employment)

Harms

Setting: All settings

General Search Strategy

Search strategies will be developed in consultation with a research librarian, and will be peer reviewed by a second research librarian using the instrument for Peer Review of Search Strategies. We will conduct a review of the literature by systematically searching, reviewing, and analyzing the scientific evidence as it pertains to the research questions. To identify relevant systematic reviews/meta-analyses, we will begin by searching Ovid MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid MEDLINE, Ovid PsycINFO, CINAHL, Epistomonikos, and Ovid EBM Reviews Cochrane Database of Systematic Reviews (CDSR, DARE, HTA, Cochrane CENTRAL, etc.). We will search all available years of publication from database inception (1946 for Ovid MEDLINE®) through January 2019. To identify additional reviews, we will review the bibliographies of relevant reviews of reviews, search the review registry Prospero for completed reviews, and query subject matter experts.

Panel Size

Key Questions

KQ1: How should panel size be determined for a primary care provider? What is the optimal size of a patient panel in primary care? Is there evidence to suggest that MD, NP and PAs should have different panel sizes? Is there evidence from large health systems in terms of setting and maintaining panel sizes?

KQ2: Should primary care panel sizes be risk adjusted for patient complexity? If yes, how should risk adjustment be accomplished?

PICOTS

Population(s): Adults

Comparator: Any comparison of differences in panel sizes in primary care

Outcome(s): Risk adjustment used to determine primary care panel sizes, clinical quality, cost, access, equity, patient experience/satisfaction

Setting: Primary care

General Search Strategy

We will procure literature from Web of Science and PubMed.

Gadolinium Agents for Patients with CKD

PROSPERO registration number: CRD42019135783

Background/Objectives of Review

The Nephrology Field Advisory Committee (FAC) provides independent advice to VA Specialty Care Services (SCS) on clinical policy and program development. The mission of the FAC is to provide National VA Renal program oversight, forward field concerns, assist in distributing information to the field, and serve as a resource to other VACO program offices.

This review will directly guide the FAC’s recommendations for development of national and local policies on Class 2 and Class 3 gadolinium use, the need for laboratory screening, and the need for informed consent prior to contrast administration for MRI scans.

Key Questions

KQ1: When exposed to macrocyclic or newer linear gadolinium-based contrast agents, what is the incidence of nephrogenic systemic fibrosis among:

  1. a) All patients?
  2. b) Patients with acute or chronic kidney disease?
  3. c) Patients with key risk factors for kidney disease (such as diabetes and hypertension)?

KQ2: When compared to older linear gadolinium-based agents, what is the relative risk of nephrogenic systemic fibrosis due to exposure to macrocyclic or newer linear gadolinium-based contrast agents among:

  1. a) All patients?
  2. b) Patients with acute or chronic kidney disease?
  3. c) Patients with key risk factors for kidney disease (such as diabetes and hypertension)?

PICOTS

Population(s): Adults, children, and autopsy

Interventions: ACR Class II gadolinium-based contrast agents: Gadoteridol (Prohance), Gadobenate dimeglumine, gadobenic acid (MultiHance),Gadobutrol (Gadavist, Gadovist, Gadograf), Gadoterate meglumine, Gadoteric acid (Dotarem, Clariscan, Artirem)

ACR Class III: Gadoxetate disodium (Eovist, Primovist)

We will also include Class I gadolinium agents when compared to Class II or III agents.

Comparator: Any or no comparators

Outcome(s): Nephrogenic systemic fibrosis (including “NSF” and nephrogenic fibrosing dermopathy (either confirmed or suspected cases; cases associated with multiple types of gadolinium agents or multiple doses also acceptable)

Setting: Gadolinium agents administered for any reason, outpatient or inpatient, in any country

General Search Strategy

We will conduct a primary search from inception to the current date of MEDLINE® (via PubMed®), Embase, Cochrane Register of Controlled Trials, and Web of Science. We will use a combination of MeSH keywords and selected free-text terms to search titles and abstracts. To ensure completeness, search strategies will be developed in consultation with an expert librarian. We will also hand search key references for relevant citations that may not be captured by our database search. Depending on the depth of the peer-reviewed literature, we may also search for case reports of NSF among patients exposed to newer gadolinium agents in the FDA (FAERS) database.

Key Questions

KQ1: What are the effectiveness, comparative effectiveness, and harms of deprescribing interventions among adults age 65 and older?

KQ1a: What are the identified elements/components that contribute the most to the effectiveness of deprescribing interventions?

KQ1b: Do the effectiveness, comparative effectiveness, and harms of deprescribing interventions vary by patient population, provider factors, or setting?

KQ2: What are the identified facilitators and barriers that impact the implementation of deprescribing interventions within large-scale health systems such as the VA?
