Integrated virtual medical consultations versus traditional clinic care in a public and a private outpatient service.

Objectives: The iConnect Care programme provided integrated 'virtual care' (VC) for patients with chronic kidney disease (CKD) in the South Eastern Sydney Local Health District. VC is an alternative to outpatient care which expedites time to specialists' opinions and is safe. Comparing different outpatient care models is important to understand the role of telehealth and integrated care, especially following the COVID-19 pandemic. This study aimed to compare a VC model with existing CKD outpatient care. Design participants and setting: A multisite, comparative, retrospective cohort study with parallel groups. 374 patients with mild CKD were recruited (July 2013 and August 2015) from public and private outpatients and followed for 12 months (n=304) or via VC (n=70). Estimated glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (ACR) were compared at baseline, 6 and 12 months. Results: At 12 months, no significant differences existed among groups in eGFR or ACR or haemoglobin, but serum creatinine was lower in the VC cohort. A significant difference existed in time to see a patient from time of referral; 7 days for VC clinic and 35-42 days for outpatient clinic. Patients interviewed felt VC was efficient and they were well managed. Conclusion: VC can be a faster mechanism to access a nephrologist and other specialists. It provided similar outcomes to outpatient care. VC represents an additional assessment and follow-up pathway supported in the community. Time to deliver is similar, but specific resources are needed. It has the potential to evolve into a standard component of chronic disease care.

iConnect CKD - virtual medical consulting: A web-based chronic kidney disease, hypertension and diabetes integrated care program.

AIMS: Chronic kidney disease patients overwhelm specialist services and can potentially be managed in the primary care (PC). Opportunistic screening of high risk (HR) patients and follow-up in PC is the most sustainable model of care. A 'virtual consultation' (VC) model instead of traditional face to face (F2F) consultations was used, aiming to assess efficacy and safety of the model. METHODS: Seventy patients were recruited from PC sites and hospital clinics and followed for 1 year. The HR patients (eGFR < 30 mL/min/1.73m2 +/- albuminuria >30 mg/mmol/L) were randomized to either VC or F2F. Patients were monitored in 6 monthly follow-up cycles by a Clinical Nurse Specialist. The specialist team provided virtual or clinical support and included a Nephrologist, Endocrinologist, Cardiologist and Renal 'Palliative' Supportive Care. RESULTS: Sixty one (87%) patients were virtually tracked or consulted with 14 (23%) being HR. At 12 months, there was no difference in outcomes between VC and F2F patients. All patients were successfully monitored. General practitioners reported a high level of satisfaction and supported the model, but found software integration challenging. Patients found the system attractive and felt well managed. Specialist consults occurred within a week, and if a second specialist opinion was required, it took another 2 weeks. CONCLUSIONS: The programme demonstrated safe, expedited and efficient follow up with a clinical and web based programme. Support from the general practitioners and patients was encouraging, despite logistical issues. Ongoing evaluation of VC services will continue and feasibility to larger networks and more chronic diseases remains the long term goal.

Laser capture microdissection and multiplex-tandem PCR analysis of proximal tubular epithelial cell signaling in human kidney disease.

Interstitial fibrosis, a histological process common to many kidney diseases, is the precursor state to end stage kidney disease, a devastating and costly outcome for the patient and the health system. Fibrosis is historically associated with chronic kidney disease (CKD) but emerging evidence is now linking many forms of acute kidney disease (AKD) with the development of CKD. Indeed, we and others have observed at least some degree of fibrosis in up to 50% of clinically defined cases of AKD. Epithelial cells of the proximal tubule (PTEC) are central in the development of kidney interstitial fibrosis. We combine the novel techniques of laser capture microdissection and multiplex-tandem PCR to identify and quantitate "real time" gene transcription profiles of purified PTEC isolated from human kidney biopsies that describe signaling pathways associated with this pathological fibrotic process. Our results: (i) confirm previous in-vitro and animal model studies; kidney injury molecule-1 is up-regulated in patients with acute tubular injury, inflammation, neutrophil infiltration and a range of chronic disease diagnoses, (ii) provide data to inform treatment; complement component 3 expression correlates with inflammation and acute tubular injury, (iii) identify potential new biomarkers; proline 4-hydroxylase transcription is down-regulated and vimentin is up-regulated across kidney diseases, (iv) describe previously unrecognized feedback mechanisms within PTEC; Smad-3 is down-regulated in many kidney diseases suggesting a possible negative feedback loop for TGF-ß in the disease state, whilst tight junction protein-1 is up-regulated in many kidney diseases, suggesting feedback interactions with vimentin expression. These data demonstrate that the combined techniques of laser capture microdissection and multiplex-tandem PCR have the power to study molecular signaling within single cell populations derived from clinically sourced tissue.
