Service redesign interventions to reduce waiting time for paediatric rehabilitation and therapy services: A systematic review of the literature.

Despite well-documented benefits of rehabilitation and therapy services for children with disabilities, long waiting lists to access these services are common. There is a growing body of evidence, primarily from mixed or adult services, demonstrating that waiting times can be reduced through strategies that target wasteful processes and support services to keep up with demand. However, providers of rehabilitation and therapy services for children face additional complexities related to the long-term nature of many developmental conditions and the need to consider timing of interventions with developmental milestones and education transition points. This review aimed to synthesise available evidence on service redesign strategies in reducing waiting time for paediatric therapy services. We conducted a systematic review of studies conducted in outpatient paediatric rehabilitation or therapy settings, including physical and mental health services, evaluating a service redesign intervention and presenting comparative data on time to access care. Two reviewers independently applied inclusion criteria, assessed risk of bias and extracted data. Findings were analysed descriptively and the certainty of evidence was synthesised according to criteria for health service research. From 1934 studies identified, 33 met the criteria for inclusion. Interventions were categorised as rapid response strategies, process efficiency interventions or substitution strategies (using alternative providers in place of medical specialists). Reductions in waiting time were reported in 30 studies. Evidence is limited by study designs with high risk of bias, but this is mitigated by consistency of findings and large effect sizes. There is moderate-certainty evidence that service redesign strategies similar to those used in adult populations can be applied in paediatric rehabilitation and therapy settings to reduce waiting time.

Return on investment of a model of access combining triage with initial management: an economic analysis.

OBJECTIVES: Timely access to outpatient services is a major issue for public health systems. To address this issue, we aimed to establish the return on investment to the health system of the implementation of an alternative model for access and triage (Specific Timely Appointments for Triage: STAT) compared with a traditional waitlist model. DESIGN: Using a prospective pre-post design, an economic analysis was completed comparing the health system costs for participants who were referred for community outpatient services post-implementation of STAT with a traditional waitlist comparison group. SETTING: Eight community outpatient services of a health network in Melbourne, Australia. PARTICIPANTS: Adults and children referred to community outpatient services. INTERVENTIONS: STAT combined targeted activities to reduce the existing waiting list and direct booking of patients into protected assessment appointments. STAT was compared with usual care, in which new patients were placed on a waiting list and offered appointments as space became available. OUTCOMES: Health system costs included STAT implementation costs, outpatient health service use, emergency department presentations and hospital admissions 3 months before and after initial outpatient appointment. Waiting time was the primary outcome. Incremental cost-effectiveness ratios (ICERs) were estimated from the health system perspective. RESULTS: Data from 557 participants showed a 16.9 days or 29% (p<0.001) reduction in waiting time for first appointment with STAT compared with traditional waitlist. The ICER showed a cost of $A10 (95% CI -19 to 39) per day reduction in waiting time with STAT compared with traditional waitlist. Modelling showed the cost reduced to $A4 (95% CI -25 to 32) per day of reduction in waiting, if reduction in waiting times is sustained for 12 months. CONCLUSIONS: There was a significant reduction in waiting time with the introduction of STAT at minimal cost to the health system.

Motivational interviewing with community-dwelling older adults after hip fracture (MIHip): protocol for a randomised controlled trial.

INTRODUCTION: Community-dwelling people recovering from hip fracture have the physical capacity to walk in their community but lack the confidence to do so. The primary aim of this trial is to determine whether motivational interviewing increases time spent walking at 12 months in community-dwelling people after hip fracture compared with an attention placebo control group. Secondary aims are to evaluate cost effectiveness, patient and health service outcomes and to complete a process evaluation. METHODS AND ANALYSIS: An assessor-blinded parallel group randomised controlled design with embedded health economic evaluation and process evaluation will compare the effects of n=270 participants randomly allocated to an experimental group (motivational interviewing) or a control group (dietary advice). For inclusion, participants are aged ≥65 years, living at home independently within 6 months of discharge from hospital after hip fracture and able to walk independently and communicate with conversational English. Key exclusion criteria are severe depression or anxiety, impaired intellectual functioning and being medically unstable to walk. Participants allocated to the experimental group will receive 10 (8 weekly and 2 booster) telephone-based sessions of motivational interviewing to increase walking over 16 weeks. Participants allocated to the control group will receive an equivalent dose of telephone-based dietary advice. The primary outcome is daily time spent walking over 7 days assessed at weeks 0, 9, 26 and 52. Secondary outcomes include measures of psychological-related function, mobility-related function, community participation, health-related quality of life and falls. Health service utilisation and associated costs will be assessed. Process evaluation will assess the fidelity of the motivational interviewing intervention and explore contextual factors through semistructured interviews. ETHICS AND DISSEMINATION: Ethical approval obtained from Eastern Health (E19-002), Peninsula Health (50261/EH-2019), Alfred Health (617/20) and La Trobe University (E19/002/50261). The findings will be disseminated in peer-reviewed journals, conference presentations and public seminars. TRIAL REGISTRATION NUMBER: ACTRN12619000936123.

Sustainable waiting time reductions after introducing the STAT model for access and triage: 12-month follow up of a stepped wedge cluster randomised controlled trial.

BACKGROUND: Timely access is a challenge for providers of outpatient and community-based health services, as seen by the often lengthy waiting lists to manage demand. The Specific Timely Appointments for Triage (STAT) model, an alternative approach for managing access and triage, reduced waiting time by 34% in a stepped wedge cluster randomised controlled trial involving 8 services and more than 3000 participants. Follow up periods ranged from 3 to 10 months across the participating services in accordance with the stepped wedge design. This study aimed to determine whether outcomes were sustained for a full 12 months after implementation of the STAT model at each site. METHODS: Routinely collected service data were obtained for a total of 12 months following implementation of the STAT model at each of the 8 services that participated in a stepped wedge cluster randomised controlled trial. The primary outcome was time to first appointment. Secondary outcomes included non-attendance rates, time to second appointment and service use over 12 weeks. Outcomes were compared to pre-intervention data from the original trial, modelled using generalised linear mixed effects models accounting for clustering of sites. RESULTS: A 29% reduction in waiting time could be attributed to STAT over 12 months, compared to 34% in the original trial. A reduction in variability in waiting time was sustained. There were no significant changes in time to second appointment or in the number of missed appointments in the extended follow up period. CONCLUSIONS: STAT is an effective strategy for reducing waiting time in community-based outpatient services. At 12 months, small reductions in the overall effect are apparent, but reductions in variability are sustained, suggesting that people who previously waited the longest benefit most from the STAT model. TRIAL REGISTRATION: This is a 12-month follow up of a stepped wedge cluster randomised controlled trial that was registered with the Australia and New Zealand Clinical Trials Registry ( ACTRN12615001016527 ).

Home visits by occupational therapists improve adherence to recommendations: Process evaluation of a randomised controlled trial.

INTRODUCTION: As part of hospital discharge planning, occupational therapists often provide recommendations to improve the interaction between a person and their home environment. The aim of this study was to investigate the number and type of recommendations made by occupational therapists during a home assessment visit compared to hospital-based assessment for patients recovering from hip fracture. A secondary aim was to explore adherence rates to the different types of recommendations. METHODS: Process evaluation of a randomised controlled trial of 65 participants recovering from hip fracture, returning to community living after hospital discharge. All participants received inpatient multidisciplinary rehabilitation and hospital-based assessment by an occupational therapist (usual care). In addition, the intervention group participated in a single home visit with an occupational therapist prior to hospital discharge. Analysis included the number and type of occupational therapy recommendations, adherence to recommendations at 30 days after discharge, and mediation analysis. RESULTS: Participants in the home visit group received more recommendations than the usual care group (mean difference [MD] 2.8, 95% CI 1.6 to 3.9) and adhered to a greater proportion of recommendations for assistive technologies (MD 11.4%, 95% CI 2.6 to 20.2) and task modifications (MD 10.0%, 95% CI 0.7 to 19.3). Participants in both groups had lower rates of adherence to recommendations for home modifications compared with other types of recommendations. Adherence to recommendations was a mediator in the relationship between participants' involvement in a pre-discharge home visit and reduced hospital readmissions. CONCLUSION: There was greater adherence to occupational therapy recommendations when patients recovering from hip fracture participated in a home visit compared to hospital-based assessment, contributing to reduced readmissions to hospital in the first 30 days. Home visits offer additional benefits to hospital-based assessment through the use of a collaborative approach to decision making in the home environment.

Saturday allied health services for geriatric evaluation and management: A controlled before-and-after trial.

OBJECTIVE: To assess the effect of Saturday allied health services on a geriatric evaluation and management ward. METHODS: A controlled before-and-after trial at two wards. Allied health services were added to usual weekday staffing on Saturdays for 6 months on the experimental ward. Length of stay, functional independence, readmissions, discharge destination and costs were evaluated at pre-intervention (N = 331) and intervention (N = 462). RESULTS: Relative to the comparison ward, the experimental ward had longer length of stay (mean 7.8 days, 95% CI 4.7-10.8), fewer readmissions (mean 3.1 days, 95% CI 0.6-5.7) and no difference in the proportion discharged home. Cost-effectiveness demonstrated no significant difference in cost ($2639, 95% CI $-386 to $5647) and functional independence gain (3.6 units, 95% CI 0.8-6.5) favouring the experimental ward. CONCLUSION: These findings do not support the provision of additional Saturday allied health services in geriatric evaluation and management to reduce length of stay.

Are wait lists inevitable in subacute ambulatory and community health services? A qualitative analysis.

Objectives Wait lists are common in ambulatory and community-based services. The aim of the present study was to explore managers' perceptions of factors that contribute to wait times. Methods A qualitative study was conducted using semi-structured interviews with managers and team leaders of ambulatory and community health services within a large health network. Interviews were transcribed and coded, and the codes were then grouped into themes and subthemes. Results Representatives from 26 services participated in the project. Four major themes were identified. Three themes related to reasons and factors contributing to increased wait time for services (inefficient intake and scheduling processes; service disruptions due to human resource issues; and high service demand). A fourth theme related to staff attitudes towards wait times and acceptance and acknowledgement of wait lists. Conclusions Service providers perceive high demand to be a key driver of wait times, but a range of other factors also contributes and may represent opportunities for improving access to care. These other factors include improving process efficiencies, greater consistency of service delivery through more efficient management of human resources and shifting to more consumer-centred approaches in measuring wait times in order to drive improvements in patient flow. What is known about the topic? Wait times are common in out-patient and ambulatory services. These services experience high demand, which is likely to continue to grow as health service delivery shifts from hospital to community settings. What does this paper add? Although demand is an important driver of wait times, there are other modifiable factors that also contribute, including process inefficiencies and service disruption related to human resource issues. An underlying staff attitude of acceptance of wait times appears to be an additional barrier to improving access. What are the implications for practitioners? The findings of the present study suggest that there are opportunities for improving access to ambulatory and community health services through more efficient use of existing resources. However, a more consumer-focused approach regarding acceptability of wait times is needed to help drive change.

Home exercise programmes supported by video and automated reminders compared with standard paper-based home exercise programmes in patients with stroke: a randomized controlled trial.

OBJECTIVE: To determine whether patients with stroke receiving rehabilitation for upper limb deficits using smart technology (video and reminder functions) demonstrate greater adherence to prescribed home exercise programmes and better functional outcomes when compared with traditional paper-based exercise prescription. DESIGN: Randomized controlled trial comparing upper limb home exercise programmes supported by video and automated reminders on smart technology, with standard paper-based home exercise programmes. SETTING: A community rehabilitation programme within a large metropolitan health service. SUBJECTS: Patients with stroke with upper limb deficits, referred for outpatient rehabilitation. INTERVENTIONS: Participants were randomly assigned to the control (paper-based home exercise programme) or intervention group (home exercise programme filmed on an electronic tablet, with an automated reminder). Both groups completed their prescribed home exercise programme for four weeks. MAIN MEASURES: The primary outcome was adherence using a self-reported log book. Secondary outcomes were change in upper limb function and patient satisfaction. RESULTS: A total of 62 participants were allocated to the intervention ( n = 30) and control groups ( n = 32). There were no differences between the groups for measures of adherence (mean difference 2%, 95% CI -12 to 17) or change in the Wolf Motor Function Test log transformed time (mean difference 0.02 seconds, 95% CI -0.1 to 0.1). There were no between-group differences in how participants found instructions ( p = 0.452), whether they remembered to do their exercises ( p = 0.485), or whether they enjoyed doing their exercises ( p = 0.864). CONCLUSIONS: The use of smart technology was not superior to standard paper-based home exercise programmes for patients recovering from stroke. This trial design was registered prospectively with the Australian and New Zealand Clinical Trials Register, ID: ACTRN 12613000786796. http://www.anzctr.org.au/trialSearch.aspx.

Improving access for community health and sub-acute outpatient services: protocol for a stepped wedge cluster randomised controlled trial.

BACKGROUND: Waiting lists for treatment are common in outpatient and community services, Existing methods for managing access and triage to these services can lead to inequities in service delivery, inefficiencies and divert resources from frontline care. Evidence from two controlled studies indicates that an alternative to the traditional "waitlist and triage" model known as STAT (Specific Timely Appointments for Triage) may be successful in reducing waiting times without adversely affecting other aspects of patient care. This trial aims to test whether the model is cost effective in reducing waiting time across multiple services, and to measure the impact on service provision, health-related quality of life and patient satisfaction. METHODS/DESIGN: A stepped wedge cluster randomised controlled trial has been designed to evaluate the impact of the STAT model in 8 community health and outpatient services. The primary outcome will be waiting time from referral to first appointment. Secondary outcomes will be nature and quantity of service received (collected from all patients attending the service during the study period and health-related quality of life (AQOL-8D), patient satisfaction, health care utilisation and cost data (collected from a subgroup of patients at initial assessment and after 12 weeks). Data will be analysed with a multiple multi-level random-effects regression model that allows for cluster effects. An economic evaluation will be undertaken alongside the clinical trial. DISCUSSION: This paper outlines the study protocol for a fully powered prospective stepped wedge cluster randomised controlled trial (SWCRCT) to establish whether the STAT model of access and triage can reduce waiting times applied across multiple settings, without increasing health service costs or adversely impacting on other aspects of patient care. If successful, it will provide evidence for the effectiveness of a practical model of access that can substantially reduce waiting time for outpatient and community services with subsequent benefits for both efficiency of health systems and patient care.

Pre-discharge home assessment visits in assisting patients' return to community living: A systematic review and meta-analysis.

OBJECTIVE: To determine the effectiveness of pre-discharge home assessment visits by occupational therapists in assisting hospitalized patients from a range of settings to return to community living. DATA SOURCES: Electronic databases MEDLINE, CINAHL, Embase, PsychINFO, Cochrane Central Register of Controlled Trials and OTseeker were searched until February 2014. STUDY SELECTION: Quantitative and qualitative studies were included if they evaluated pre-discharge home assessment visits by an occupational therapist. Of 1,778 potentially relevant articles, 14 studies met the inclusion criteria. DATA EXTRACTION: After data extraction, study quality was assessed using check-lists. DATA SYNTHESIS: Pre-discharge home assessment visits reduced the risk of falling (risk ratio 0.68, 95% confidence interval (95% CI) 0.49-0.94) and increased participation levels (standardized mean difference 0.49; 95% CI 0.01-0.98) in geriatric and mixed rehabilitation settings. The risk of readmission to hospital was also reduced (risk ratio 0.47, 95% CI 0.33-0.66), but not for patients following stroke. There was no effect on activity or quality of life. Patients and carers perceived that home assessment visits were beneficial and were satisfied with the process. CONCLUSION: There is low-to-moderate quality evidence that pre-discharge home assessment visits reduce patients' risk of falling and increase participation. The risk of readmission to hospital is also reduced, but not for patients following stroke.

Reducing waiting time for community rehabilitation services: a controlled before-and-after trial.

OBJECTIVE: To investigate whether a simple alternative (specific timely appointments for triage [STAT]) to the more common approach of managing demand using a waitlist with a triage system could reduce waiting time for a community rehabilitation program (CRP) without adverse impacts on patient care. DESIGN: A prospective, controlled before-and-after trial. Preintervention and postintervention data were collected for 6 months in 2 consecutive years. STAT was introduced at an intervention site and compared with a control site using a triaged waitlist. SETTING: Two musculoskeletal CRP teams within a large metropolitan health service. PARTICIPANTS: All patients referred to both sites during periods preintervention (n=483) and postintervention (n=488). INTERVENTION: Under STAT, clinicians created a specified number of assessment times each week based on average referral numbers, and patients were immediately allocated an appointment on referral. MAIN OUTCOME MEASURES: The primary outcome was the time from referral to first appointment; secondary outcomes included program duration, quality-of-life scores (using the EuroQol EQ-5D), and unplanned hospital admissions. RESULTS: Waiting time decreased from a mean of 17.5 days to 10.0 days (P<.01) at the intervention site, with no significant change at the control site. Intervention site patients were over 3 times more likely to be seen within 7 days than control site patients (odds ratio, 3.3; 95% confidence interval, 2.2-4.9). Secondary outcomes did not differ significantly between groups. CONCLUSIONS: A simple alternative to using a triaged waitlist to manage CRP referrals reduced waiting time without adversely affecting care. Results were sustained over 6 months with no additional resources.

Effect of triage on waiting time for community rehabilitation: a prospective cohort study.

OBJECTIVE: To investigate how the allocation of referrals for a community rehabilitation service to triage categories affects waiting time from referral to first appointment, and whether other factors also contribute to variance in waiting time. DESIGN: A prospective cohort study. SETTING: A multidisciplinary outpatient community rehabilitation program within a large metropolitan health service. PARTICIPANTS: Consecutive adult patients (N=379) commencing rehabilitation over a 3-month period. INTERVENTION: Allocation of referrals to a triage category of 1 (most urgent) to 4 (least urgent) by allied health clinicians guided by a written protocol. MAIN OUTCOME MEASURE: The primary outcome was waiting time from referral to service commencement. RESULTS: The small group of patients (4%) allocated to the most urgent category had significantly shorter mean waiting times than the other 3 categories (mean, 4.8d vs 19.6, 26.6, and 19.4d for categories 2, 3, and 4, respectively). Regression analysis indicated that approximately 11% of the variance in waiting time was accounted for by the triage categories. Site of treatment (home or center) and diagnosis also made small contributions (4% combined) to variance in waiting time. CONCLUSIONS: The triage process ensured rapid service for a small number of urgent referrals, but made little difference to the waiting time of the vast majority of patients. Given the resources required for triaging patients, the results of this study lead us to question the value of the triage system in this setting.

A training programme did not increase agreement between allied health clinicians prioritizing patients for community rehabilitation.

OBJECTIVE: To evaluate the effect of formal training on agreement between clinicians making decisions on client priority. SETTING: A centralized intake service receiving referrals for a community rehabilitation programme. DESIGN: Agreement was measured between the priority categories allocated to consecutive referrals by one of five clinicians in the referral office compared with a second rating made by an independent occupational therapist, blinded to the initial priority rating. Data collection followed the implementation of four 1-hour workshops involving all raters, designed to increase consistency of triage decisions. Results were compared to a previous study conducted prior to the training. PARTICIPANTS: Two hundred and one consecutive referrals received for community rehabilitation services, triaged by experienced clinicians with allied health or nursing qualifications. OUTCOME MEASURE: Agreement using weighted kappa (κ(w)). RESULTS: There was no change in agreement between clinicians after training, compared with a previous study in the same setting. Agreement remained moderate (κ(w) = 0.50), with clinicians disagreeing on approximately 30% of referrals. CONCLUSIONS: Three out of 10 clients will receive a different priority rating and waiting time for rehabilitation services depending on which clinician in the referral office made the rating. This result was not improved by conducting a training programme.
