Appraising the quality of tools used to record patient-reported outcomes in users of augmentative and alternative communication (AAC): a systematic review

Identifying Components of a Person-Centered Augmentative and Alternative Communication Intervention for People With Dementia: Opinions of an International Expert Panel

PURPOSE

Despite general agreement on the importance of person-centered care in speech-language pathology, guidelines for developing person-centered interventions for those with dementia are limited. This study aimed to obtain expert opinion on the components of a person-centered augmentative and alternative communication (AAC) intervention for persons with dementia.

METHOD

A modified electronic Delphi technique was employed in a single round. A purposively sampled panel of experts was invited to provide their opinion on three open-ended questions related to (a) the elements of person-centered care, (b) communication supports, and (c) the interaction outcomes of a person-centered intervention. Thirty-one experts from nine countries participated on the panel. The majority were speech-language pathologists primarily involved in research. Qualitative written data were coded and analyzed using content analysis.

RESULTS

Nine components were identified across the three open-ended questions: (a) the unique characteristics of the person with dementia, (b) working with a person with dementia, (c) preserving personhood, (d) a different view on person-centered care, (e) a range of communication supports, (f) supportive conversational partners, (g) designing communication supports, (h) interaction outcome measure, and (i) meaningful interaction outcomes.

CONCLUSION

This study identified nine components that are useful in guiding speech-language pathologists in crafting future person-centered AAC interventions for people with dementia.

A qualitative evidence synthesis of the experiences and perspectives of communicating using augmentative and alternative communication (AAC)

PURPOSE

This paper presents a review of the existing qualitative research literature concerning people's experience of communicating using augmentative and alternative communication (AAC). The aims of conducting this review were to find out more about the values and outcomes that are important to people about the AAC they use to support their communication. This review was conducted to provide a deeper understanding of these experiences to inform the development of a patient-reported outcome measure (PROM).

MATERIALS AND METHODS

A qualitative evidence synthesis of existing qualitative research literature was undertaken to explore and appraise current knowledge about the experiences of people who use AAC.

RESULTS

From 115 qualitative research reports 19 papers were identified that responded directly to the research question and aims of the review. Data were identified that could be organized within an a priori framework consisting of the constructs of values, outcomes, and context.

CONCLUSION

The review has resulted in a deeper, analytical understanding of the experiences of people who require AAC. The results indicate a set of concepts that can be used to inform the development of a PROM. A PROM can be used to assist clinicians and researchers to better understand the perspectives of people who require AAC and evaluate interventions. The results also encourage professionals to reconsider the terminology and methods used when working alongside people who require AAC and to reflect on the multidimensional factors that influence people's experience of communication.

Advancing Methodological Rigor for Psychosocial Aspects of Neuropalliative Care Interventions

Background: Neurological disorders (NDs) have unique biopsychosocial-spiritual features that impact patients and their families. As a result, the subspeciality of neuropalliative care (NPC) emerged within the past decade and has grown exponentially in research and practice. Given the cognitive, emotional, and behavioral changes associated with NDs, psychosocial components (eg, coping skills) of NPC interventions are essential for improving the quality of life for patients and families. However, psychosocial components of NPC interventions warrant more rigorous testing to improve their evidence base and their likelihood of implementation and dissemination. Aim: In this commentary, we provide methodological recommendations with the goal of improving scientific knowledge and rigor for psychosocial components of multicomponent NPC interventions in clinical trials. Results: We emphasize the need for transparent reporting of psychosocial intervention components; using established models of intervention development to guide the development and testing of multicomponent NPC interventions; identifying mechanisms of action for psychosocial outcomes; and choosing psychometrically sound measures for mechanisms and outcomes. Conclusions: Given the importance of psychosocial care to the holistic NPC model, rigorous testing of psychosocial components of NPC interventions is a high priority for clinical investigators to advance the evidence base and practice of NPC.

A scoping review of communication outcomes measures in augmentative and alternative communication

Although outcomes are a critical component of evidence-based practice, measuring augmentative and alternative communication (AAC) outcomes remains problematic. This is, in part, because there is no consensus on how to operationally define AAC communication outcomes. To gain greater insight into AAC communication outcomes, we used the communicative competence framework to determine which areas of AAC intervention have received the greatest attention and how these outcomes are being measured. The following data were charted from the 77 studies that met the inclusion criteria for the scoping review: study design, study participants, study communication target (e.g., language, word learning, etc.), and communication outcome measurements. Across the included studies, researchers used a variety of standardized and non-standardized measures to assess outcomes. Seventy-seven percent of the studies assessed social skills and 62% assessed linguistic skills. A limited number of studies measured operational (14%), strategic (4%), and psychosocial (18%) skills. Using the communicative competence framework enabled us to identify gaps in the research that has been conducted to date.

What does a "good life" mean for people living with dementia? A protocol for a think-aloud study informing the value of care

Introduction

Economic evaluation currently focuses almost exclusively on the maximization of health, using the Quality-Adjusted Life-Year (QALY) framework with instruments such as the EQ-5D, with a limited number of health-focused dimensions providing the assessment of health benefit. This evaluative framework is likely to be insufficient for setting priorities in dementia care because of its exclusive concern with health. Data are also often collected from the perspective of a proxy, limiting the voice of those living with dementia in decision-making. This protocol describes a research project that aims to gather the perspectives of people living with dementia, their insights, and preferences for assessing their quality of life to inform economic evaluation outcome measurement and design with a goal of creating a more robust evidence base for the value of healthcare services. Specifically, this study will elucidate what a "good life" means to people living with dementia and how well instruments currently used in economic evaluation meet this description. This project will further test the acceptability of capability wellbeing instruments as self-report instruments and compare them to generic and dementia-specific preference-based instruments.

Methods and analysis

People living with dementia, diagnosed, or waiting to receive a formal diagnosis and with the capacity to participate in research, will be invited to participate in an hour "think aloud" interview. Participants will be purposefully selected to cover a range of dementia diagnoses, age, and sex, recruited through the integrated care, geriatric, and post-diagnostic clinics at St James' and Tallaght University Hospitals and dementia support groups in the Ireland. During the interview, participants will be invited to reflect on a "good life" and "think aloud" while completing four economic quality of life instruments with a perspective that goes beyond health (AD-5D/QOL-AD, AQOL-4D, ICECAP-O, ICECAP-SCM). An interviewer will then probe areas of difficulty when completing the instruments in a semi-structured way. The analysis will identify the frequency of errors in comprehension, retrieval, judgment, and response from verbatim transcripts. Qualitative data will be analyzed using constant comparison.

Ethics

The St James's Hospital and Tallaght University Hospital Joint Research Ethics Committee approved the study (Approval Date: 11 April 2022).

Feasibility of Customized Pillboxes to Enhance Medication Adherence: A Randomized Controlled Trial

OBJECTIVE

To test the (1) feasibility of an assistive technology based pillbox intervention on medication adherence; (2) feasibility of trial procedures; and (3) preliminary effectiveness of the pillbox intervention on medication adherence.

DESIGN

A single-blinded randomized controlled clinical trial was conducted during 2-4 weeks.

SETTING

Researchers recruited a convenience sample to participate in this university laboratory-based study.

PARTICIPANTS

English-speaking consumers of 2 or more daily medications (N=15) participated in the study. Individuals with cognitive impairment or who did not manage their own medications were excluded.

INTERVENTIONS

Participants were randomized to 1 of 3 pillbox interventions: (1) standard-of-care pillbox; (2) customized off-the-shelf pillbox; or (3) customized 3-dimensional (3D) printed pillbox.

MAIN OUTCOME MEASURES

Outcome measures were divided among the 3 goals of the study. In addition to feasibility metrics, the Adherence to Refills and Medications Scale was used to measure the primary outcome measure, medication adherence. The Quebec User Evaluation of Satisfaction with Assistive Technology was used to measure pillbox satisfaction.

RESULTS

Researchers successfully administered 6 standard-of-care, 5 custom off-the-shelf, and 4 custom 3D printed pillboxes. Compared with the standard-of-care pillboxes, customized 3D printed pillboxes had large (d=1.04) and customized off-the-shelf pillboxes had medium (d=0.67) effects on medication adherence.

CONCLUSIONS

Prescription of customized pillboxes using a manualized and novel assistive technology approach that leverages 3D printing is feasible.

Patient reported outcomes in oncology: changing perspectives-a systematic review

In public health context, oncology is associated with severe negative impact on patients and on their relatives’ quality of life. Over the last decades, survival has remained at 50% worldwide for some tumor locations. Patient reported outcomes (PROs) assessment and, the corresponding use in clinical practice, help establishing patient individualized profiling involving caregivers. The purpose of this systematic review was to examine critical success factors for PROs assessment in daily clinical oncology practice. Additionally, we investigated how PROs collection can change oncology perspectives for patients and caregivers. According to PRISMA guidelines, 83 studies were included in this systematic review, whether related with implementation in daily clinical practice or associated with its use in oncology. PROs assessment gathers multi-professional teams, biomedical and clinical expertise, patients, families and caregivers. Institutional involvement, first line for caregiver’s adherence, team continuous formation, encompassing training and support, design of clear workflows, continuous monitoring, and data analysis are crucial for implementation. PROs measures are decisive in oncology. Several items were improved, including caregiver–patient–physician communication, patient risk groups identification, unmet problems and needs detection, disease course and treatment tracking, prognostic markers, cost-effectiveness measurement and comfort/support provision for both patients and caregivers. Routine assessment and implementation of PROs in clinical practice are a major challenge and a paradigm transformation for future.

Applying Implementation Science to Support Active Collaboration in Noninvasive Brain-Computer Interface Development and Translation for Augmentative and Alternative Communication

PURPOSE

The purpose of this article is to consider how, alongside engineering advancements, noninvasive brain-computer interface (BCI) for augmentative and alternative communication (AAC; BCI-AAC) developments can leverage implementation science to increase the clinical impact of this technology. We offer the Consolidated Framework for Implementation Research (CFIR) as a structure to help guide future BCI-AAC research. Specifically, we discuss CFIR primary domains that include intervention characteristics, the outer and inner settings, the individuals involved in the intervention, and the process of implementation, alongside pertinent subdomains including adaptability, cost, patient needs and recourses, implementation climate, other personal attributes, and the process of engaging. The authors support their view with current citations from both the AAC and BCI-AAC fields.

CONCLUSIONS

The article aimed to provide thoughtful considerations for how future research may leverage the CFIR to support meaningful BCI-AAC translation for those with severe physical impairments. We believe that, although significant barriers to BCI-AAC development still exist, incorporating implementation research may be timely for the field of BCI-AAC and help account for diversity in end users, navigate implementation obstacles, and support a smooth and efficient translation of BCI-AAC technology. Moreover, the sooner clinicians, individuals who use AAC, their support networks, and engineers collectively improve BCI-AAC outcomes and the efficiency of translation, the sooner BCI-AAC may become an everyday tool in the AAC arsenal.

Caregiver burden and proxy-reported outcomes of people without natural speech: a cross-sectional survey study

OBJECTIVE

To examine interrelations between care-related burden on informal caregivers and their proxy assessments of outcomes in people without natural speech.

DESIGN

A cross-sectional survey.

SETTING

Data were collected in January 2019 from a postal survey of informal caregivers of people without natural speech who are insured by a large regional health insurance company in the German federal state of Lower Saxony.

PARTICIPANTS

n=714 informal caregivers of people without natural speech of all ages and with various underlying disabilities were identified and contacted via the health insurance company. Data from n=165 informal caregivers (26.4%) were obtained.

MAIN OUTCOME MEASURES

Caregiver burden (self-reported, Burden Scale for Family Caregivers), pragmatic communication skills of people without natural speech (proxy report, self-developed), health-related quality of life of people without natural speech (proxy report, DISABKIDS Chronic Generic Measure - DCGM-12) and functioning of people without natural speech (proxy report, WHO Disability Assessment Schedule 2.0).

RESULTS

The analyses revealed significant associations between caregiver burden on the one hand and both proxy-reported health-related quality of life (b=-0.422; p≤0.001) and functioning (b=0.521; p≤0.001) on the other. Adding caregiver burden to the regression model leads to a substantial increase in explained variance in functioning (R² Model 1=0.349; R² Model 2=0.575) as well as in health-related quality of life (R² Model 1=0.292; R² Model 2=0.460).

CONCLUSIONS

Caregiver burden should be considered an important determinant when informal caregivers report outcomes on behalf of people without natural speech. Longitudinal studies are recommended to better understand the burdens experienced by caregivers when supporting people without natural speech.

Effectiveness and Determinant Variables of Augmentative and Alternative Communication Interventions in Cerebral Palsy Patients with Communication Deficit: a Systematic Review

PURPOSE

Assess the effectiveness of augmentative and alternative communication (AAC) interventions in patients with CP and to reveal determinant variables of main intervention outcomes: receptive and expressive language.

RESEARCH STRATEGIES

The search was performed in following databases: MEDLINE (Ovid); PubMed (NLM); Embase (Ovid); Cochrane Database of Systematic Reviews; Cumulative Index to Nursing and Allied Health Literature; Database of Abstracts of Reviews of Effects; Cochrane Central Register of Controlled Trials; Health Technology Assessment database and PEDro.

SELECTION CRITERIA

Full-text and peer-reviewed studies in English studying the effectiveness of AAC in patients with cerebral palsy were included. Studies with patients (<18 years) diagnosed with CP were included.

DATA ANALYSIS

A narrative analysis was conducted to evaluate the efficacy of AAC methods. A random-effects model meta-analysis was used to assess determinants of AAC intervention outcomes.

RESULTS

The online database and manual reference search revealed 445 records. Nine studies investigating a total of 294 subjects with CP met predefined eligibility criteria: 4 studies with single subject, multiple baseline research designs, 3 longitudinal cohort studies, 1 case control study and 1 case series. Results revealed moderate-quality evidence that AAC interventions improve the receptive and expressive communication skills in patients with CP. The random-effects model meta-analysis revealed the power of identified determinant variables affecting the AAC intervention outcomes.

CONCLUSION

Diversity of CP patients requires proper analysis of determinant variables to ensure the efficacy of AAC assessment and intervention. More studies of high methodological and practical quality assessing the efficacy of AAC interventions are needed to clarify the evidence.
