Evaluating the Feasibility and Validity of Using Trained Allied Health Assistants to Assist in Mealtime Monitoring of Dysphagic Patients

Delegation of patient related tasks to allied health assistants: a time motion study

Background

Allied health assistants (AHAs) are support staff who complete patient and non-patient related tasks under the delegation of an allied health professional. Delegating patient related tasks to AHAs can benefit patients and allied health professionals. However, it is unclear whether the AHA workforce is utilised optimally in the provision of patient care. The purpose of this study was to determine the proportion of time AHAs spend on patient related tasks during their working day and any differences across level of AHA experience, clinical setting, and profession delegating the task.

Methods

A time motion study was conducted using a self-report, task predominance work sampling method. AHAs were recruited from four publicly-funded health organisations in Victoria, Australia. AHAs worked with dietitians, occupational therapists, physiotherapists, podiatrists, social workers, speech pathologists, psychologists, and exercise physiologists. The primary outcome was quantity of time spent by AHAs on individual task-categories. Tasks were grouped into two main categories: patient or non-patient related activities. Data were collected from July 2020 to May 2021 using an activity capture proforma specifically designed for this study. Logistic mixed-models were used to investigate the extent to which level of experience, setting, and delegating profession were associated with time spent on patient related tasks.

Results

Data from 51 AHAs showed that AHAs spent more time on patient related tasks (293 min/day, 64%) than non-patient related tasks (167 min/day, 36%). Time spent in community settings had lower odds of being delegated to patient related tasks than time in the acute hospital setting (OR 0.44, 95%CI 0.28 to 0.69, P < 0.001). Time delegated by exercise physiologists and dietitians was more likely to involve patient related tasks than time delegated by physiotherapists (exercise physiology: OR 3.77, 95% 1.90 to 7.70, P < 0.001; dietetics: OR 2.60, 95%CI 1.40 to 1.90, P = 0.003). Time delegated by other professions (e.g. podiatry, psychology) had lower odds of involving patient related tasks than physiotherapy (OR 0.37, 95%CI 0.16 to 0.85, P = 0.02).

Conclusion

AHAs may be underutilised in community settings, and by podiatrists and psychologists. These areas may be targeted to understand appropriateness of task delegation to optimise AHAs’ role in providing patient care.

The challenges and gains of delivering a home-exercise intervention: a qualitative study of physiotherapists and physiotherapy assistants

OBJECTIVES

The paper presents insights from the Community based Rehabilitation after Knee Arthroplasty (CORKA) trial. We aimed to explore physiotherapists and physiotherapy assistants' experiences of delivering a home-base exercise intervention following knee replacement surgery. We were particularly interested in the feasibility, potential benefits and barriers of a community-based exercise programme from the perspective of physiotherapists and physiotherapy assistants and to understand any constraints or training needs that arose.  DESIGN: Qualitative thematic analysis of semi-structured interviews.  SETTING: The Community based Rehabilitation after Knee Arthroplasty (CORKA) trial.

PARTICIPANTS

Five physiotherapists and six physiotherapy assistants with a range of clinical experience.

METHODS

Interviews were digitally recorded and transcribed verbatim. We used the stages of reflexive thematic analysis suggested by Braun and Clarke. One researcher conducted the interviewers whilst three researchers with experience in qualitative research methods contributed to the coding and analysis of data.

RESULTS

We developed seven themes that help to understand the benefits and challenges of delivering treatment interventions in a person's home: seeing the person in their own world; thinking outside the cubicle;developing people skills; enjoying the above and beyond; treading a fine line between patient and friend; feeling outside my comfort zone; needing a support network.

CONCLUSIONS

Treating people in their own homes facilitates a holistic approach. Our findings highlight areas for clinical education: (1) how do we help clinicians to tread the fine line between friend and professional (2) how do we balance the need to provide support and structure with the freedom to work creatively and independently?

Examining the Content and Outcomes of Training in Dysphagia and Mealtime Management: A Systematic Review Informing Co-Design of New Training

PURPOSE

Dysphagia (swallowing difficulty) impacts physical health, quality of life, and mealtime enjoyment. Staff who provide mealtime assistance to people with dysphagia require adequate training to help ensure that the mealtimes are safe and enjoyable. This systematic review examined literature relating to training in dysphagia (e.g., recognizing signs and symptoms) and mealtime assistance, its components, and benefits for people with dysphagia.

METHOD

In July 2020, five scientific databases were searched for papers meeting the inclusion criteria relating to mealtime assistance training. The quality of the studies was evaluated using the Quality Assessment Tool for Studies of Diverse Design, with scores ranging from 38.1% to 83.3%. We completed a qualitative synthesis using the data extracted from the included studies.

RESULTS

Twenty-four studies met the inclusion criteria. Participants in these studies benefited from both group training and one-on-one training. Training programs had many formats including computer-based, face-to-face, individual training, and group training. Each included study demonstrated some level of positive impact to the learners, such as improved knowledge and skills in mealtime management for people with dysphagia. No studies reported negative outcomes. Training duration ranged from 30 min to 5 days.

CONCLUSIONS

The benefits of different components of mealtime training (e.g., group training, or face-to-face training) for mealtime assistance for people with dysphagia were reviewed. Further research is needed to compare the effectiveness of different training formats, involving not only the assistant but also people with dysphagia as both trainers and trainees, and determine the health outcomes of training programs for people with dysphagia.

Introduction of a speech-language pathology assistant role for swallow screening in a head and neck radiotherapy clinic

PURPOSE

Optimal care suggests that all moderate-high risk head and neck (H&N) cancer patients should receive speech pathology assessment, education and management when commencing radiotherapy. However this is not always feasible due to high patient numbers and limited staffing. The aim of this study was to investigate the implementation of a speech-language pathology assistant (SLP-A) role for swallowing screening and education in a multidisciplinary H&N treatment clinic.

METHOD

A detailed model of care and training module were developed to up-skill the SLP-A in the screening and education to be undertaken. A pre-test post-test design compared outcomes in two separate groups prior to and following SLP-A role implementation. Outcomes included: optimal care compliance, speech-language pathology time spent with complex patients, swallowing-related admissions and patient satisfaction.

RESULT

Twenty-six patients were included pre-implementation and 35 post-implementation, with 16 (46%) patients receiving SLP-A screening/education post-implementation. The proportion of eligible patients seen by speech-language pathology pre-implementation was 62%, compared to 94% seen by speech-language pathology or SLP-A post-implementation (p = 0.002). There was a (non-significant) increase in speech-language pathology time spent with complex patients post-implementation (total minutes per patient: mean 252, SD = 144 vs. 279, SD = 115). There was no increase in swallowing-related admissions, and a (non-significant) increase in patient satisfaction post-implementation, indicating no compromise to patient safety or satisfaction.

CONCLUSION

Implementing a speech-language pathology assistant role for screening patients within the H&N treatment clinic allowed delivery of optimal care and increased time for speech-language pathologists to spend with complex patients, without compromising patient safety or satisfaction.

Evaluating the Use of Oral Trials for Inpatient Dysphagia Management: An Initial Cross-Sectional Database Study

Purpose Oral trials, otherwise known as swallow trials or tasters, are widely used in dysphagia management. However, to date, no studies have investigated the effectiveness of oral trials or outlined how the approach is utilized in everyday practice. This article aims to start a dialogue regarding this much-used but little-evidenced dysphagia intervention by exploring three main aspects to (a) identify the patient demographics and environments in which oral trials are used in hospital, (b) explore clinical decision making around the approach, and (c) consider clinical implications around current findings and future areas for research. Method A cross-sectional examination of 118 patients on the dysphagia caseload of a United Kingdom-based inpatient speech and language therapy team was conducted. Statistical analysis explored demographic differences between oral trials groups and the rest of the dysphagia caseload. Results Twenty-three of 118 (19.5%) individuals on the caseload were or had been on oral trials during admission. Individuals in the oral trials group were significantly more likely to have a neurological diagnosis than the full oral intake group (78.3% vs. 30.5%, p < .001). There was a lack of uniformity in oral trials recommendations, and the rationale behind quantity and types of diet or fluids offered was unclear. Conclusions This study begins to evidence the use of a dysphagia therapy not previously explored within existing literature. It highlights the wide use of oral trials within the hospital trust observed. Based on current evidence, it would be difficult for clinicians to know how to implement oral trials as an intervention. Further research is required both to explore the effectiveness of this approach and also to develop a consensus within practice around how, why, and when oral trials are offered. This would ensure an equitable and effective service is offered and would ensure a high standard of evidence-based practice within dysphagia management.

Outpatient physiotherapy versus home-based rehabilitation for patients at risk of poor outcomes after knee arthroplasty: CORKA RCT

BACKGROUND

Over 100,000 primary knee arthroplasty operations are undertaken annually in the UK. Around 15-30% of patients do not report a good outcome. Better rehabilitation strategies may improve patient-reported outcomes.

OBJECTIVES

To compare the outcomes from a traditional outpatient physiotherapy model with those from a home-based rehabilitation programme for people assessed as being at risk of a poor outcome after knee arthroplasty.

DESIGN

An individually randomised, two-arm controlled trial with a blinded outcome assessment, a parallel health economic evaluation and a nested qualitative study.

SETTING

The trial took place in 14 NHS physiotherapy departments.

PARTICIPANTS

People identified as being at high risk of a poor outcome after knee arthroplasty.

INTERVENTIONS

A multicomponent home-based rehabilitation package delivered by rehabilitation assistants with supervision from qualified therapists compared with usual-care outpatient physiotherapy.

MAIN OUTCOME MEASURES

The primary outcome was the Late Life Function and Disability Instrument at 12 months. Secondary outcomes were the Oxford Knee Score (a disease-specific measure of function); Knee injury and Osteoarthritis Outcome Score; Quality of Life subscale; Physical Activity Scale for the Elderly; EuroQol-5 Dimensions, five-level version; and physical function assessed using the Figure-of-8 Walk Test, 30-Second Chair Stand Test and Single Leg Stance. Data on the use of health-care services, time off work and informal care were collected using participant diaries.

RESULTS

In total, 621 participants were randomised. A total of 309 participants were assigned to the COmmunity based Rehabilitation after Knee Arthroplasty (CORKA) home-based rehabilitation programme, receiving a median of five treatment sessions (interquartile range 4-7 sessions). A total of 312 participants were assigned to usual care, receiving a median of four sessions (interquartile range 2-6 sessions). The primary outcome, Late Life Function and Disability Instrument function total score at 12 months, was collected for 279 participants (89%) in the home-based CORKA group and 287 participants (92%) in the usual-care group. No clinically or statistically significant difference was found between the groups (intention-to-treat adjusted difference 0.49 points, 95% confidence interval -0.89 to 1.88 points; p = 0.48). There were no statistically significant differences between the groups in any of the patient-reported or physical secondary outcome measures at 6 or 12 months post randomisation. The health economic analysis found that the CORKA intervention was cheaper to provide than usual care (£66 less per participant). Total societal costs (combining health-care costs and other costs) were lower for the CORKA intervention than usual care (£316 less per participant). Adopting a societal perspective, CORKA had a 75% probability of being cost-effective at a threshold of £30,000 per quality-adjusted life-year. Adopting the narrower health and social care perspective, CORKA had a 43% probability of being cost-effective at the same threshold.

LIMITATIONS

The interventions were of short duration and were set within current commissioning guidance for UK physiotherapy. Participants and treating therapists could not be blinded.

CONCLUSIONS

This randomised controlled trial found no important differences in outcomes when post-arthroplasty rehabilitation was delivered using a home-based, rehabilitation assistant-delivered rehabilitation package or a traditional outpatient model. However, the health economic evaluation found that when adopting a societal perspective, the CORKA home-based intervention was cost-saving and more effective than, and thus dominant over, usual care, owing to reduced time away from paid employment for this group. Further research could look at identifying the risk of poor outcome and further evaluation of a cost-effective treatment, including the workforce model to deliver it.

Exploring the Validity and Operational Impact of Using Allied Health Assistants to Conduct Dysphagia Screening for Low-Risk Patients Within the Acute Hospital Setting

Purpose The purpose of this study was to examine (a) the agreement between allied health assistants (AHAs) and speech-language pathologists (SLPs) when completing dysphagia screening for low-risk referrals and at-risk patients under a delegation model and (b) the operational impact of this delegation model. Method All AHAs worked in the adult acute inpatient settings across three hospitals and completed training and competency evaluation prior to conducting independent screening. Screening (pass/fail) was based on results from pre-screening exclusionary questions in combination with a water swallow test and the Eating Assessment Tool. To examine the agreement of AHAs' decision making with SLPs, AHAs (n = 7) and SLPs (n = 8) conducted an independent, simultaneous dysphagia screening on 51 adult inpatients classified as low-risk/at-risk referrals. To examine operational impact, AHAs independently completed screening on 48 low-risk/at-risk patients, with subsequent clinical swallow evaluation conducted by an SLP with patients who failed screening. Results Exact agreement between AHAs and SLPs on overall pass/fail screening criteria for the first 51 patients was 100%. Exact agreement for the two tools was 100% for the Eating Assessment Tool and 96% for the water swallow test. In the operational impact phase (n = 48), 58% of patients failed AHA screening, with only 10% false positives on subjective SLP assessment and nil identified false negatives. Conclusion AHAs demonstrated the ability to reliably conduct dysphagia screening on a cohort of low-risk patients, with a low rate of false negatives. Data support high level of agreement and positive operational impact of using trained AHAs to perform dysphagia screening in low-risk patients.

Delegation by Allied Health Professionals to Allied Health Assistants: a mixed methods systematic review

BACKGROUND

Delegation by Allied Health Professionals (AHPs) to Allied Health Assistants (AHAs) was introduced in response to various challenges affecting modern health care delivery. However, the clinical and cost-effectiveness of using AHAs is relatively unexplored.

OBJECTIVES

The aim of this review was to synthesise the available evidence on; firstly, the clinical and cost-effectiveness of interventions delegated by AHPs to AHAs and secondly, AHPs', AHAs' and patients' attitudes and beliefs towards delegation.

DATA SOURCES

MEDLINE, AMED, CINAHL, Cochrane Library, PsycINFO, PEDro, OTseeker and Web of Science databases were searched from inception until January 2019 without restrictions.

STUDY SELECTION

Primary studies investigating the clinical and cost-effectiveness of any intervention delegated by an AHP, across the spectrum of clinical areas in relation to adult patients, as well as AHPs', AHAs' and patients' attitudes and beliefs about delegation.

DATA EXTRACTION & SYNTHESIS

Data were extracted by pairs of reviewers. Thematic analysis and synthesis of descriptive and analytical themes was conducted.

RESULTS

Thirteen publications of variable methodological quality were included. Three studies reported quantitative research and ten qualitative research. No study explored the cost-effectiveness. Only one study investigated clinical effectiveness. Training for both AHPs and AHAs and having clear processes in place were identified as important facilitators of delegation.

CONCLUSION AND IMPLICATIONS OF KEY FINDINGS

Delegation is not standardised across AHPs or within each profession. There are clear knowledge gaps regarding the clinical and cost-effectiveness of delegation by AHPs and patients' attitudes and preferences. Further research is needed to facilitate the standardisation of delegation.

Dysphagia screening using an allied health assistant delegation model: service considerations for implementation

PURPOSE

Three facilities, involved in introducing a model of Allied Health Assistant (AHA) delegated dysphagia screening, examined barriers and facilitators to service implementation.

MATERIALS AND METHODS

The 3 facilities varied in size, services and location. AHAs (n = 4) and speech-language therapists (SLTs; n = 4) directly involved in implementation at each site completed semi-structured interviews exploring the implementation experience. Analysis was guided by the Consolidated Framework for Implementation Research (CFIR).

RESULTS

There was differential implementation across the sites. Facilitators to implementation fell within the CFIR Innovation Characteristic domain, with the "relative advantage" of the model and "design, quality and packaging" of the training and implementation resources being key facilitators. Barriers related to the Innovation Characteristic domain, regarding the tool's "adaptability" in terms of screening tools selected and the implementation environment. Issues with the Inner Setting domain, specifically the "structural characteristics," the "compatibility" of the model and the "relative priority" of the model's implementation within other organizational priorities were also barriers.

CONCLUSIONS

Although the service model was perceived to have relative advantage, compatibility with local work-flow priorities and service needs must be thoroughly considered if AHA delegated dysphagia screening is to be beneficial as a service model to address increasing dysphagia referral demands.IMPLICATIONS FOR REHABILITATIONDysphagia is a disabling condition which may result in medical, social and operational complications.The demands of screening, assessing, managing and providing rehabilitation for dysphagia are increasing, therefore alternative models of service delivery including delegation are increasingly being considered and implemented.This study provides evidence regarding the context and facilitators of successful AHA dysphagia screening model implementation.This evidence contributes to a growing knowledge base of delegation practices for the management of staffing resources and building of capacity for rehabilitation service delivery.

Delegation models in dysphagia management: Current policy, clinical perceptions and practice patterns

Purpose: Delegation to Allied Health Assistants (AHAs) is an effective workforce solution in a number of areas of adult speech-language pathology (SLP) practice. However, reports of AHA delegation in the area of dysphagia management are limited. The aim of this study was to synthesise information from policy documents and current clinical practice to examine the nature of AHA delegation in dysphagia management.Method: A mixed method design involving a document review of 13 policy documents on AHA delegation, and a survey of 44 SLP managers regarding current delegation models.Result: Policy and current practice were largely congruent. Despite policy support for AHA delegation, 77% reported using delegation models but only 26% used them fairly often/very often in dysphagia management. Both policy and survey findings support AHA training prior to task delegation, however, the nature of training was unspecified. Good governance is integral to successful delegation and managers recognised the need to increase standardisation of AHA capability assessment.Conclusion: AHA delegation in dysphagia management is supported by policy and is being implemented in clinical services. However further work detailing governance and training requirements is needed, as well as systematic evaluation of the safety and benefits of these models.
