The role of an integrated referral program for patients with liver disease: A network between hub and spoke centers

INTRODUCTION

Access to Liver transplantation (LT) can be affected by several barriers, resulting in delayed referral and increased risk of mortality due to complications of the underlying liver disease.

AIM

To assess the clinical characteristics and outcomes of patients with acute or chronic liver disease referred using an integrated referral program.

MATERIALS AND METHODS

An integrated referral program was developed in 1 October 2017 based on email addresses and a 24/7 telephone availability. All consecutive adult patients with liver disease referred for the first time using this referral program were prospectively collected until 1 October 2021. Characteristics and outcomes of inpatients were compared with a historical cohort of patients referred without using the integrated referral program (1 October 2015-1 October 2017). Patients were further divided according to pre- and post-Covid-19 pandemic.

RESULTS

Two hundred eighty-one referred patients were considered. End stage liver disease was the most common underlying condition (79.3%), 50.5% of patients were referred as inpatients and 74.7% were referred for LT evaluation. When inpatient referrals (n = 142) were compared with the historical cohort (n = 86), a significant increase in acute liver injury due to drugs/herbals and supplements was seen (p = 0.01) as well as an increase in End stage liver disease due to alcohol-related liver disease and NASH, although not statistically significant. A significant increase in referrals for evaluation for Trans-jugular intrahepatic portosystemic shunt placement was seen over time (5.6% vs. 1%; p = 0.01) as well as for LT evaluation (84.5% vs. 81%; p = 0.01). Transplant-free survival was similar between the study and control groups (p = 0.3). The Covid-19 pandemic did not affect trends of referrals and patient survival.

CONCLUSIONS

The development of an integrated referral program for patients with liver disease can represent the first step to standardize already existing referral networks between hub and spoke centers. Future studies should focus on the timing of referral according to different etiologies to optimize treatment options and outcomes.

Results of a fast-track referral system for urgent outpatient hepatology visits

OBJECTIVE

In 2011, our regional district adopted an experimental system for fast referral (within 72 h) by general practitioners to several outpatient specialist evaluations including hepatology. The aim of this study was to assess the characteristics and appropriateness of urgent hepatology visits.

DESIGN

Retrospective study.

SETTING

Hospital-based study in Italy.

PARTICIPANTS

A total of 192 subjects referred to our outpatient hepatology clinic classified as 'urgent' were compared with 397 patients evaluated with standard referral. A comparison with 200 patients visited just before the adoption of the new system was also included.

MAIN OUTCOME MEASURES

Patients' features and appropriateness of referral in urgent and non-urgent groups using the new system.

RESULTS

Increase in liver enzymes was the main factor that leads to specialist hepatology consultation and was more frequent in the urgent group (37% vs. 27.1%, P < 0.001). Liver malignancies were identified in 2.6% of patients in the urgent group, whereas this percentage was 10 times lower in the non-urgent group (P = 0.01). Urgent patients required inpatient admission more frequently compared with non-urgent patients (4.2% vs. 0.5%; P = 0.003). Inappropriate referral was recorded in 41% of cases in the urgent group (no reason for urgency 27%; condition not attributable to liver 13.5%). In the non-urgent group, consultations were inappropriate in 20.1% of cases (condition not attributable to liver). In comparison with the old system, the new one allocated >85% of patients with serious illness to urgent group.

CONCLUSIONS

This strategy is helpful in selecting patients with more serious hepatic conditions. Appropriateness of referral represents a crucial issue.
