Effect of a Layperson-Delivered Telephone Program for People With Depressive Symptoms

OBJECTIVE

This study investigated whether a layperson-delivered telephone program focusing on empathy could improve depressive symptoms among adults.

METHODS

Data for a subset of participants from a randomized controlled trial (July 6-September 24, 2020) were analyzed to assess the impact of a telephone program on mental health. Participants in this post hoc analysis had baseline depressive symptoms and were assessed for depression, anxiety, loneliness, and isolation.

RESULTS

Of the 240 people in the original sample, 58 had depressive symptoms (i.e., baseline scores of ≥10 on the eight-item Patient Health Questionnaire [PHQ-8]); 56 of the 58 were reassessed 4 weeks later. Participants in the intervention arm had greater improvements in PHQ-8 scores (baseline mean±SD=13.0±2.6, postintervention mean=9.2±3.0; mean difference=3.8, 95% CI=2.9-4.7) than participants in the control arm (mean difference=1.3, 95% CI=0.1-2.5) (p=0.013).

CONCLUSIONS

This telephone intervention, delivered by a lay workforce, holds promise for reducing the burden on the clinical care system.

Community-based HIV testing in The Netherlands: experiences of lay providers and end users at a rapid HIV test checkpoint

BACKGROUND

The AIDS Healthcare Foundation (AHF-Checkpoint) in The Netherlands offers rapid HIV testing for key populations by lay providers. We explored the experiences and needs of lay providers and end users of HIV testing at AHF-Checkpoint, taking into account the WHO 5C-(consent, confidentiality, counselling, correct-results, connection-to-care) criteria for HIV test services.

METHODS

Qualitative evaluation with 15 semi-structured interviews conducted during 2020 with ten lay providers and five gay or bisexual end users. Recorded interviews were thematically analysed, taking data triangulation into account.

RESULTS

Four domains were identified: (1) accessibility of HIV testing, (2) quality of test procedures, (3) bridging (transitional care), and (4) future strategies for service delivery. AHF-Checkpoint fills a gap for key populations including LGBTQ and refugees, who experience HIV testing barriers at sexual health centres or general practices. The level of trust between lay providers and end users was highly valued by end users. They appreciated the low threshold to test at no costs, and the absence of waiting lists or triaging. Needs expressed by lay providers included more preparedness for emotionally charged situations, and extra training to improve STI knowledge. End users expressed a need for a full STI test package. Of the 5Cs, consent, counselling, and correct results were realised but confidentiality was sometimes difficult to achieve at pop-up locations, and referral barriers for confirmation testing (connection-to-care) were occasionally experienced by lay providers during weekends.

CONCLUSION

AHF-Checkpoint was described as a convenient and easily accessible service by end users and lay providers. Of the WHO 5Cs, connection-to-care could be optimised to ensure HIV confirmation and STI testing through a liaison approach with professionals from the regular healthcare sector.

Self-help guided by trained lay providers for generalized anxiety disorder in older adults: study protocol for a randomized controlled trial

Background

Only a small proportion of older patients with generalized anxiety disorder (GAD) seek professional help. Difficulties in accessing treatment may contribute to this problem. Guided self-help based on the principles of cognitive-behavioral therapy (GSH-CBT) is one way of promoting access to psychological treatment. Moreover, because the therapist’s role in GSH-CBT is limited to supporting the patient, this role could be assumed by trained and supervised lay providers (LPs) instead of licensed providers. The main goal of this study is to evaluate the efficacy of GSH-CBT guided by LPs for primary threshold or subthreshold GAD in older adults.

Methods

We will conduct a multisite randomized controlled trial comparing an experimental group receiving GSH-CBT guided by LPs (n = 45) to a wait-list control group (n = 45). Treatment will last 15 weeks and will be based on a participant’s manual. Weekly telephone sessions with LPs (30 min maximum) will be limited to providing support. Data will be obtained through clinician evaluations and self-assessment questionnaires. Primary outcomes will be the tendency to worry and severity of GAD symptoms. Secondary outcomes will be anxiety symptoms, sleep difficulties, functional deficit, diagnosis of GAD, and cognitive difficulties. For the experimental group, measurements will take place at pre- and post-treatment and at 6 and 12 months post-treatment. For the control group, three evaluations are planned: two pre-treatment evaluations (before and after the waiting period) and after receiving treatment (post-treatment). The efficacy of GSH-CBT will be established by comparing the change in the two groups on the primary outcomes.

Discussion

This project will provide evidence on the efficacy of a novel approach to treat GAD in older adults. If effective, it could be implemented on a larger scale and provide many older adults with much needed mental health treatment through an expanded workforce.

Trial registration

The trial was registered at ClinicalTrials.gov, number NCT03768544, on December 7, 2018.

Implementing a Status-Neutral Approach to HIV in the Asia-Pacific

PURPOSE OF REVIEW

Globally, "undetectable equals untransmittable (U=U)" and "pre-exposure prophylaxis (PrEP)" have become crucial elements in HIV treatment and prevention programs. We reviewed the implementation of U=U and PrEP among countries in the Asia-Pacific region.

RECENT FINDINGS

U=U and PrEP uptakes were limited and slow in the Asia-Pacific. Inadequate knowledge among health care practitioners and pervasive stigma towards individuals living with HIV and their sexual lives are key barriers for the integration of U=U into clinical practice. Paternalistic and hierarchical health care systems are major obstacles in PrEP implementation and scale-up. Countries with the most advanced PrEP implementation all use community-based, nurse-led, and key population-led service delivery models. To advance U=U and PrEP in the Asia-Pacific, strategies targeting changes to practice norm through wide-scale stakeholders' training and education, making use of online health care professional influencers, and utilizing financial mechanism should be further explored through implementation research.

Task-shifting of CD4 T cell count monitoring by the touchscreen-based Muse™ Auto CD4/CD4% single-platform system for CD4 T cell numeration: Implication for decentralization in resource-constrained settings

BACKGROUND

The accuracy of CD4 T cell monitoring by the recently developed flow cytometry-based CD4 T cell counting Muse™ Auto CD4/CD4% Assay analyzer (EMD Millipore Corporation, Merck Life Sciences, KGaA, Darmstadt, Germany) was evaluated in trained lay providers against laboratory technicians.

METHODS

After 2 days of training on the Muse™ Auto CD4/CD4% analyzer, EDTA-blood samples from 6 HIV-positive and 4 HIV-negative individuals were used for CD4 T cell counting in triplicate in parallel by 12 trained lay providers as compared to 10 lab technicians.

RESULTS

Mean number of CD4 T cells in absolute number was 829 ± 380 cells/μl by lay providers and 794 ± 409 cells/μl by technicians (P > 0.05); and in percentage 36.2 ± 14.8%CD4 by lay providers and 36.1 ± 15.0%CD4 by laboratory technician (P > 0.05). The unweighted linear regression and Passing-Bablok regression analyses on CD4 T cell results expressed in absolute count revealed moderate correlation between CD4 T cell counts obtained by lay providers and lab technicians. The mean absolute bias measured by Bland-Altman analysis between CD4 T cell/μl obtained by lay providers and lab technicians was -3.41 cells/μl. Intra-assay coefficient of variance (CV) of Muse™ Auto CD4/CD4% in absolute number was 10.1% by lay providers and 8.5% by lab technicians (P > 0.05), and in percentage 5.5% by lay providers and 4.4% by lab technicians (P > 0.05). The inter-assay CV of Muse™ Auto CD4/CD4% in absolute number was 13.4% by lay providers and 10.3% by lab technicians (P > 0.05), and in percentage 7.8% by lay providers and 6.9% by lab technicians (P > 0.05).

CONCLUSIONS

The study demonstrates the feasibility of CD4 T cell counting using the alternative flow cytometer Muse™ Auto CD4/CD4% analyzer by trained lay providers and therefore the practical possibility of decentralization CD4 T cell counting to health community centers.

Can trained lay providers perform HIV testing services? A review of national HIV testing policies

BACKGROUND

Only an estimated 54% of people living with HIV are aware of their status. Despite progress scaling up HIV testing services (HTS), a testing gap remains. Delivery of HTS by lay providers may help close this testing gap, while also increasing uptake and acceptability of HIV testing among key populations and other priority groups.

METHODS

50 National HIV testing policies were collated from WHO country intelligence databases, contacts and testing program websites. Data regarding lay provider use for HTS was extracted and collated. Our search had no geographical or language restrictions. This data was then compared with reported data from the Global AIDS Response Progress Reporting (GARPR) from July 2015.

RESULTS

Forty-two percent of countries permit lay providers to perform HIV testing and 56% permit lay providers to administer pre-and post-test counseling. Comparative analysis with GARPR found that less than half (46%) of reported data from countries were consistent with their corresponding national HIV testing policy.

CONCLUSIONS

Given the low uptake of lay provider use globally and their proven use in increasing HIV testing, countries should consider revising policies to support lay provider testing using rapid diagnostic tests.

Enabling lay providers to conduct CBT for older adults: key steps for expanding treatment capacity

The Institute of Medicine advocates the examination of innovative models of care to expand mental health services available for older adults. This article describes training and supervision procedures in a recent clinical trial of cognitive behavioral therapy (CBT) for older adults with generalized anxiety disorder (GAD) delivered by bachelor-level lay providers (BLPs) and to Ph.D.-level expert providers (PLPs). Supervision and training differences, ratings by treatment integrity raters (TIRs), treatment characteristics, and patient perceptions between BLPs and PLPs are examined. The training and supervision procedures for BLPs led to comparable integrity ratings, patient perceptions, and treatment characteristics compared with PLPs. These results support this training protocol as a model for future implementation and effectiveness trials of CBT for late-life GAD, with treatment delivered by lay providers supervised by a licensed provider in other practice settings.
