This systematic review aimed to evaluate the effect of eHealth-delivered interventions for adults who undergo bariatric surgery on postoperative weight loss, weight loss maintenance, eating psychopathology, quality of life, depression screening, and self-efficacy. Six electronic databases were searched, with 14 studies (across 17 reports) included, involving 1633 participants. With substantial heterogeneity, qualitative descriptions have been provided. Interventions were delivered via an online program or internet modules (n 5 2), telephone (n 5 2), text messages (n 5 2), videoconferencing (n 5 3), mobile application (n 5 1), and audiovisual media (n 5 1). Three studies included a combination, including internet modules and telephone (n 5 1), wireless fidelity scales, emails, and telephone (n 5 1), and a combination of online treatment, weekly emails, and access to a private Facebook group (n 5 1). All the eHealth interventions, except for one, implemented behavior change techniques, including self-monitoring, problem solving, social support, goal setting, and shaping knowledge. Both eHealth intervention and control groups lost weight across the included studies, and eHealth was found to be as effective as or more effective than the control for weight loss. Two studies measured weight loss maintenance; both eHealth and control groups regained weight in the longer term. The interventions showed significant improvement on assessment measures for eating psychopathology. In conclusion, when bariatric surgery patients have limited or no access to healthcare teams or require additional support, eHealth may be a suitable option. Future studies implementing eHealth interventions would benefit from reporting intervention components as per the behavior change techniques taxonomy and further consideration of delivering eHealth in a stepped care approach would be beneficial.

Objectives: To identify outcome measures used to evaluate performance of healthcare professional role substitution against usual medical doctor or specialist medical doctor care to facilitate our understanding of the adequacy of these measures in assessing quality of healthcare delivery. Methods: Using a systematic approach, we searched Medline, Cochrane Central Register of Controlled Trials, Embase, CINAHL, and Web of Science from database inception until May 2020. Studies that presented original comparative data on at least one outcome measure were included following screening by two authors. Findings were synthesized, and outcome measures classified into six domains which included: effectiveness, safety, appropriateness, access, continuity of care, efficiency, and sustainability which were informed by the Institute of Medicine dimensions of healthcare quality, the Australian health performance framework, and Levesque and Sutherland's integrated performance measurement framework.Results: One thirty five articles met the inclusion criteria, describing 58 separate outcome measures. Safety of role substitution models of care was assessed in 80 studies, effectiveness (n = 60), appropriateness (n = 40), access (n = 36), continuity of care (n = 6), efficiency and productivity (n = 45). Two-thirds of the studies that assessed productivity and efficiency performed an economic analysis (n = 27). The quality and rigour of evaluations varied substantially across studies, with two-thirds of all studies measuring and reporting outcomes from only one or two of these domains.Conclusions: There are a growing number of studies measuring the performance of non-medical healthcare professional substitution roles. Few have been subject to robust evaluations, and there is limited evidence on the scientific rigour and

ObjectiveThe demand for outpatient gastroenterology medical specialist consultations is above what can be met within budgetary and staffing constraints. This study describes the establishment of a dietitian first gastroenterology clinic to address this issue, the patient journey and its impact on wait lists and wait times in a tertiary gastroenterology service.DesignA dietitian first gastroenterology clinic model was developed and a mixed-methods approach used to evaluate the impact of the service over a 21-month period.SettingGold Coast University Hospital, Queensland, Australia (a public tertiary hospital).Patients658 patients were triaged to the clinic between June 2016 and March 2018.InterventionA dietitian first gastroenterology clinic for low-risk gastroenterology patients.Main outcome measuresWe examined demographic, referral, wait list, wait time and service activity data, patient satisfaction and patient journey.ResultsAt the time of audit, 399 new (67.9% female) and 307 review patients had been seen. Wait times for eligible patients reduced from 280 to 66 days and the percentage of those in breach of their recommended wait times reduced from 95% to zero. The average time from referral to discharge was 117.8 days with an average of 2.4 occasions of service. 277 patients (69.4%) had been discharged to the care of their general practitioner and 43 patients (10.7%) had an expedited specialist medical review. Patient surveys indicated a high level of satisfaction.ConclusionA dietitian first gastroenterology model of care helps improve patient flow, reduces wait times and may be useful elsewhere to address outpatient gastroenterology service pressures.
