The VA Evidence Synthesis Program (ESP) Coordinating Center is responding to a request from the VA Offices of Enterprise Integration (OEI) and Planning and Performance Management (OPPM), which has established an Integrated Project Team (IPT) on Homelessness. The IPT has requested a review of known risk factors for homelessness experienced by US Veterans during the pre-service, in-service, and post-service periods. Findings from this report will inform cross-VA efforts to better understand and address homelessness among Veterans.

KQ2: US Veterans (any service era) experiencing homelessness
Outcome(s): Homelessness (defined as meeting US Department of Housing and Urban Development criteria, use of any specialized VA homeless services, or documented ICD-9 clinical code suggesting homelessness)

KQ1: What are the effects of automating the delivery of oral, enteral, or parenteral nutrition supplements to hospitalized patients on patient and process outcomes?
KQ2: How is automating the delivery of oral, enteral, or parenteral nutrition supplements to hospitalized patients experienced by the staff involved in implementing and delivering it?
Population(s): KQ1: Hospitalized patients - including long-term care, skilled nursing facility residents and end of life patients - at risk of malnutrition (ie, who have difficulty eating or absorbing nutrients through GI tract)
KQ2: Hospital staff involved in automating the delivery oral, enteral, or parenteral nutrition supplements to patients (eg, nurses and nursing assistants, pharmacists, food service, registered dietitians)
Interventions: Automated nutrition delivery of oral, enteral, or parenteral nutrition supplements (ie, medical food supplements) that includes automated notifications to the hospital care team (eg, nurses and nursing assistants, physicians pharmacists, food service, registered dietitians) that nutrition supplements have been ordered/ prescribed and requires responses that the care team has administered nutrition supplements and/or how much the patient actually received (eg, electronic health record alerts, barcode scanning)
Automation is defined as the "creation of a process or application of a technology to deliver hospital-based nutrition to patients minimizing human intervention” (ie, hospital staff provide the thinking on the ordering side (inputs) and the delivery side (outputs) is automated to minimize human touch points).
Automation should include one or both of the following aspects of implementation:

KQ2:
Primary purpose of evaluation is to explore the experiences and attitudes of hospital staff (eg, nursing, pharmacy, food service, dietetics) who interact with some aspect of implementing and delivering the automated delivery of nutrition
We will conduct a primary search from inception to the current date of MEDLINE (via Ovid), Embase, and CINAHL from inception to January 16, 2022.

The VA Evidence Synthesis Program Coordinating Center is responding to a request from the Offices of Mental Health and Suicide Prevention, Research and Development, and Specialty Care Services for a systematic review of evidence on the effectiveness of syringe service programs. The review will inform development of a plan to support the goals of the National Drug Control Strategy Action Plan, and use of best practices for harm reduction in the VHA.

KQ2: Do benefits and harms of syringe service programs vary by exchange model (needs-based versus 1-for-1) or presence/absence of program components?
Population(s): Adults at risk for substance use-related harms.
Interventions: Syringe service programs. Primary intervention should be dispensing of sterile syringes, but programs may also include “wraparound” components such as fentanyl test strip and/or naloxone distribution, rapid HIV and/or hepatitis C (HCV) testing, referral to treatment and/or prevention services, or counseling/training on overdose prevention, safer injection practices, and/or infectious disease prevention (efficacy of components as standalone interventions will not be evaluated).
Comparator: Any or no comparison condition.
Outcome(s): Drug use behaviors (sharing, borrowing, lending, reuse, or unsafe disposal of syringes; amount, speed, or frequency of use); knowledge of overdose risk; naloxone distribution/use; HIV/HCV prevalence or incidence; linkage to treatment for substance use disorder, HIV/HCV, or other medical needs, or to HIV pre-exposure prophylaxis; utilization of referred services; neighborhood crime rates or property values.
Setting: Any, but we may prioritize studies using a best-evidence approach (eg, focusing on studies most relevant to the US/VA setting). Existing systematic reviews may be included to address some outcomes. Studies published before 2000 will be ineligible.
