CH ALIS Connect — FHIR Implementation Guide

FHIR R4 Implementation Guide for ALIS-Connect (ch.fhir.ig.ch-alis, canonical http://fhir.ch/ig/ch-alis).

ALIS ("Leistungsschnittstelle") is a Swiss XML interface standard by ALIS-Connect for transmitting service/billing data (Leistungen) between hospital information systems and billing systems. ALIS 5.1 supports TARDOC and outpatient flat rates (ambulante Pauschalen) managed by OAAT-OTMA: per-service diagnoses, tariff-session information (Anhang B) and lab/pathology service assignment.

This guide defines a mapping between the ALIS XML 5.1 standard and HL7 FHIR. It contains two parallel representations:

1. Logical models — a faithful 1:1 FHIR mirror of the ALIS XML schema (Visit, Service, Diagnosis, ServiceAssignment, SessionSectionB, PersonV40, ParameterV40, …).
2. Profiles — the ALIS data expressed on "real" FHIR resources for interoperability. The ChargeItem resource is the closest FHIR fit for an ALIS Service; each Service of a Visit becomes one ChargeItem (with contained Patient, Encounter and Condition), transmitted together in a transaction Bundle.

The element-level correspondence is documented in both directions: Concept Maps (logical model → FHIR profile) and FHIR Mappings (profile → ALIS field, on each profile's Mappings tab).

Building the IG

The guide is built with the HL7 FHIR IG Publisher, which runs SUSHI itself as its first step — there is no need to run sushi separately:

java -jar publisher.jar -ig ig.ini

The build compiles the FSH in input/fsh/ to fsh-generated/, then renders the site to output/ (inspect output/qa.txt for errors/warnings). Run sushi . on its own only for a quick FSH-syntax check when you don't need the rendered site.
