Capitated Telehealth Coaching Hospital Readmission Service in Australia: Pragmatic Controlled Evaluation

Abstract

Background MonashWatch is a telehealth public hospital outreach pilot service as a component of the Government of Victoria’s statewide redesign initiative called HealthLinks: Chronic Care. Rather than only paying for hospitalizations, projected funding is released earlier to hospitals to allow them to reduce hospitalization costs. MonashWatch introduced a web-based app, Patient Journey Record System, to assess the risk of the journeys of a cohort of patients identified as frequent admitters. Telecare guides call patients using the Patient Journey Record System to flag potential deterioration. Health coaches (nursing and allied health staff) triage risk and adapt care for individuals. Objective The aim was a pragmatic controlled evaluation of the impact of MonashWatch on the primary outcome of bed days for acute nonsurgical admissions in the intention-to-treat group versus the usual care group. The secondary outcome was hospital admission rates. The net promoter score was used to gauge satisfaction. Methods Patients were recruited into an intention-to-treat group, which included active telehealth and declined/lost/died groups, versus a systematically sampled (4:1) usual care group. A rolling sample of 250-300 active telehealth patients was maintained from December 23, 2016 to June 23, 2019. The outcome—mean bed days in intervention versus control—was adjusted using analysis of covariance for age, gender, admission type, and effective days active in MonashWatch. Time-series analysis tested for trends in change patterns. Results MonashWatch recruited 1373 suitable patients who were allocated into the groups: usual care (n=293) and intention-to-treat (n=1080; active telehealth: 471/1080, 43.6%; declined: 485, 44.9%; lost to follow-up: 178 /1080, 10.7%; died: 8/1080, 0.7%). Admission frequency of intention-to-treat compared to that of the usual care group did not significantly improve (P=.05), with a small number of very frequent admitters in the intention-to-treat group. Age, MonashWatch effective days active, and treatment group independently predicted bed days. The analysis of covariance demonstrated a reduction in bed days of 1.14 (P<.001) in the intention-to-treat group compared with that in the usual care group, with 1236 bed days estimated savings. Both groups demonstrated regression-to-the-mean. The downward trend in improved bed days was significantly greater (P<.001) in the intention-to-treat group (Sen slope –406) than in the usual care group (Sen slope –104). The net promoter score was 95% in the active telehealth group compared with typical hospital scores of 77%. Conclusions Clinically and statistically meaningful reductions in acute hospital bed days in the intention-to-treat group when compared to that of the usual care group were demonstrated (P<.001), although admission frequency was unchanged with more short stay admissions in the intention-to-treat group. Nonrandomized control selection was a limitation. Nonetheless, MonashWatch was successful in the context of the HealthLinks: Chronic Care capitation initiative and is expanding.

Effectiveness of a targeted telephone-based case management service on activity in an Emergency Department in the UK: a pragmatic difference-in-differences evaluation

“…Since participants and their controls were selected according to the likelihood of future ED attendance, partly informed by past high ED attendance, the observed fall in the outcomes from the prior to the intervention period could be at least partly explained by regression to the mean, where treatment allocation is based on extreme values in the prior or pre-test period. This phenomenon has been reported in other studies with similar study designs [ 19 , 20 ]. Our study, nevertheless, observed a differential effect of the intervention that was consistent across all the outcomes, albeit not significant statistically.…”

The effect of home visits on healthcare resource utilisation

“…18,19 A reduction in bed days has also been demonstrated at Monash Watch Hospital, Australia, after telehealth and coaching implementation; the improvement was more prominent in the intervention group in Martin et al's study. 20 The research group found that providing home services resulted in a decrease in admission days but an increase in outpatient visits, which was an unexpected finding. The effect on emergency room visits was not significant.…”

Ferramentas da tecnologia da informação e comunicação na jornada do paciente cirúrgico: Revisão integrativa

“…Além das contribuições na área cirúrgica, o uso de aplicativos oferece benefícios na prestação dos serviços de saúde, além de promover o autocuidado (Ferreira & Gomes Junior, 2021). Martin et al (2020) avaliaram o impacto de um serviço de telessaúde, criado com o intuito de reduzir os custos decorrentes da hospitalização. Neste sentido, foi criado um aplicativo para avaliar o risco das jornadas de pacientes admitidos frequentemente no hospital.…”
