Hamburg Doesn't Have 'The' Children's Hospital. It Has Five Children's ERs, and Three Big Children's Hospitals That Each Do Something Different

Three Hospitals, Not One Building With Three Names

The phrase “Hamburg’s children’s hospital” doesn’t point to a single address. It points to three separate institutions, each with its own campus, its own ownership structure, and its own reason for existing, and knowing which is which matters well before an emergency, whenever a Kinderarzt says the word “Überweisung” and a family has to decide where that referral should actually go. Two further hospitals, covered near the end of this page, also run their own round-the-clock children’s emergency departments.

1. 1 Altonaer Kinderkrankenhaus, Bleickenallee 38, 22763 Hamburg. UKE subsidiary since 1 September 2006, own 24/7 Zentrale Notaufnahme.
2. 2 Katholisches Kinderkrankenhaus Wilhelmstift, Liliencronstraße 130, 22149 Hamburg. Independent Catholic institution, Hamburg's largest children's hospital by bed count, own 24/7 ZNA rebuilt after the 2024 flood.
3. 3 Kinder-UKE, Martinistraße 52, Building O47, 20246 Hamburg. Part of UKE, own dedicated 24/7 children's emergency room separate from UKE's main adult ER.

Altonaer Kinderkrankenhaus: Tied to the UKE, and One of Germany’s Largest Children’s Hospitals

Altonaer Kinderkrankenhaus opened its doors on 24 May 1859 as a rented, six-bed children’s hospital on Große Wilhelminenstraße, moved into its own purpose-built home on what’s now Bleickenallee in 1914, and by its 1959 centenary had grown to 400 beds. Today it runs closer to 242 beds, organized into eleven Fachabteilungen: general pediatrics, neonatology and pediatric intensive care, pediatric orthopedics, neurosurgery, surgery and urology, trauma surgery, psychosomatics, anesthesiology, radiology, and ENT, plus seven cross-department centers including the Perinatalzentrum Altona for high-risk newborn deliveries, a spine center, and a long-term ventilation unit. AKK’s own figures describe more than 1,000 staff caring for roughly 16,000 inpatient and partial-hospitalization patients and 45,000 outpatient visits a year, drawing families from across northern Germany, not just Hamburg. Its Zentrale Notfallambulanz is open around the clock, seven days a week, and AKK says it treats about 40,000 children and teenagers a year.

What often surprises newcomers is the ownership structure sitting underneath that name. Since 1 September 2006, AKK has operated as a subsidiary of Universitätsklinikum Hamburg-Eppendorf. AKK’s own quality report calls it one of the largest and most modern children’s hospitals in Germany, and together with the newer Kinder-UKE building described below the two organizations describe themselves as forming a very large children’s clinic. AKK still runs its own campus, its own gGmbH, and its own day-to-day operations independently of UKE’s main Eppendorf site, so the connection is organizational and financial rather than a merger of buildings.

Wilhelmstift: Hamburg’s Largest Children’s Hospital, and a 2024 Flood That Just Got Fixed

Katholisches Kinderkrankenhaus Wilhelmstift in Rahlstedt has nothing to do with UKE. It’s an independently run Catholic gGmbH, founded in 1925, and despite AKK’s university connection, Wilhelmstift is actually the single largest children’s hospital in Hamburg by itself, with 261 inpatient and day-care beds against AKK’s roughly 242. Its Zentrum für Kinder- und Jugendmedizin groups eleven departments and 22 specialized areas under one roof, general pediatrics, neuropediatrics, neonatology and intensive care, pediatric surgery and hand surgery, pediatric facial surgery, dermatology, radiology, anesthesiology, and child and adolescent psychiatry, alongside more than 20 outpatient clinics and roughly 1,000 employees treating about 11,000 inpatient cases a year plus tens of thousands of outpatient visits (the hospital’s own page says 50,000, Hamburg’s government press release says 30,000 to 35,000). One department worth naming specifically: Wilhelmstift maintains a dedicated unit for severely burned children, a level of specialization not every general pediatric department offers.

Wilhelmstift’s emergency department has a genuinely recent, genuinely Hamburg-specific story attached to it. Heavy rainfall in August 2024, a Starkregen event, badly damaged the hospital’s Zentrale Notaufnahme, serious enough to force a full closure and rebuild rather than a quick patch job. Hamburg’s social affairs senator, Melanie Schlotzhauer, officially reopened the modernized department in March 2026, and the reconstruction went beyond simple repair: the centerpiece is a restructured triage area with three separate rooms for initial patient assessment, replacing what existed before the flood. The city’s Krankenhaus-Investitionsprogramm contributed roughly one million euros toward that specific triage rebuild, and Wilhelmstift separately received a roughly six-million-euro grant in December 2025 to replace aging medical equipment, including a new MRI machine and modern ventilators and incubators. If your information about Wilhelmstift’s ZNA predates March 2026, treat it as outdated.

Kinder-UKE: Where Hamburg’s Rarest Pediatric Cases Actually Go

Kinder-UKE is the newest of the three, a dedicated pediatric building on the UKE campus at Martinistraße 52 in Eppendorf that opened in autumn 2017, bringing every pediatric discipline under a single purpose-built roof with 148 beds. Its focus sits deliberately apart from AKK and Wilhelmstift’s broader general pediatric surgery and orthopedics: oncology, severe neurological and rare congenital conditions, and liver, kidney, and bone marrow transplants, the categories of illness that concentrate at a single university center rather than being spread across every children’s hospital in a city. As part of UKE’s wider Zentrum für Geburtshilfe, Kinder- und Jugendmedizin, the combined obstetrics-and-pediatrics center treats roughly 16,000 inpatient and 54,000 outpatient patients a year.

Most families reach Kinder-UKE through a Kinderarzt’s referral or a transfer once another hospital’s workup points toward one of its specialties, rather than a routine first visit. It does, however, run its own round-the-clock children’s emergency room, in Building O47 (phone 040 7410-20400, treating patients up to age 18), entirely separate from UKE’s main adult Zentrale Notaufnahme in Building O10. That distinction matters for a specific reason: Kinder-UKE’s emergency room sits outside the four officially coordinated Notfallpraxen für Kinder already documented on this site (AKK, Wilhelmstift, Helios Mariahilf, and Asklepios Nord-Heidberg), since it belongs to UKE’s own separate emergency infrastructure rather than the Arztruf Hamburg-coordinated network. For most everyday pediatric emergencies, AKK and Wilhelmstift’s Notfallpraxen and ZNAs remain the more direct route.

Two More Hospitals With Their Own Children’s ER

The three hospitals above are not the only places in Hamburg with a children’s emergency department that never closes. Helios Mariahilf Klinik Hamburg, Stader Straße 203c, 21075 Hamburg (Harburg), runs a Kinder-Notaufnahme that is open every day around the clock, staffed by pediatricians and pediatric surgeons. Helios says it treats about 13,000 children a year, assesses them with the Manchester Triage System, and that on weekends and holidays between 9:00 and 16:00 practice-based pediatricians also see patients in the department (hospital switchboard 040 790 06-0). Asklepios Klinik Nord - Heidberg, Tangstedter Landstraße 400, 22417 Hamburg (Langenhorn), runs its Kindernotaufnahme for infants, children and teenagers around the clock as part of its KinderHeidberg (hospital switchboard 040 181887-0), and a pediatric on-call service is available there on Saturdays, Sundays and holidays from 10:00 to 18:00. They sit in the south (Harburg) and the north (Langenhorn) of the city, which can matter more than a hospital’s size when a child is unwell.

What Actually Changes Inside a Children’s Emergency Department

A pediatric emergency department isn’t an adult emergency room with smaller furniture. At all three Hamburg institutions, the physicians and nurses doing the initial assessment are trained specifically in pediatric and adolescent medicine, not general emergency doctors who occasionally treat children between adult cases, and medication dosing, imaging protocols, and monitoring equipment are calibrated for a child’s body rather than scaled down from adult defaults. Waiting and treatment areas sit physically apart from any adult emergency department sharing the same hospital campus, and it’s standard practice in Germany’s system for a parent to remain with their child throughout an emergency visit rather than being asked to wait in a separate room. Triage logic doesn’t change: children are seen according to genuine medical urgency, not the order they walked through the door.

Insurance and Billing Work the Same Way at All Three

None of the three hospitals treats insurance type as a reason to send a family elsewhere. AKK, Wilhelmstift, and Kinder-UKE all accept gesetzliche Krankenversicherung (GKV, statutory insurance), private insurance (PKV), and EU health insurance cards for medically necessary treatment, exactly as already established for Hamburg’s Notfallpraxis network: your child’s insurance card covers an emergency visit like any other, with no upfront payment and no referral required. For a scheduled, non-emergency specialist appointment, whichever of the three hospitals your Kinderarzt is sending you to, a standard Überweisung is the normal route, and none of the three requires choosing based on which insurance a family carries.

Step by Step

1. Work out whether this is a true emergency or a scheduled referral firstThat decides everything else below.
2. Genuine emergency, any time: go to the nearest of AKK, Wilhelmstift, Kinder-UKE, Helios Mariahilf (Harburg) or Asklepios Nord - Heidberg (Langenhorn), or use the Notfallpraxis networkAll five run their own round-the-clock children's emergency department; this site's Kindernotdienst guide covers the separate weekday-evening and weekend Notfallpraxis schedule.
3. Rare or complex diagnosis, oncology, severe neurological or genetic disease, or a transplant: ask your Kinderarzt to refer specifically to Kinder-UKEMartinistraße 52, Building O47.
4. General pediatric surgery, orthopedics, urology, neurosurgery, or trauma: AKK and Wilhelmstift both run full departmentsAsk your Kinderarzt which currently has shorter waits.
5. Severe burn specifically: ask for Wilhelmstift's dedicated burns unit by name.
6. Bring the Gesundheitskarte and, if you have one, the yellow U-HeftRegardless of which of the three hospitals you're headed to.
7. Save the addresses of the two or three nearest to you nowBefore a decision needs to happen quickly.

Compliance Note

This page explains the general structure, ownership, and specialties of Hamburg’s three major children’s hospitals, including recent developments such as Wilhelmstift’s 2024-2026 emergency department rebuild, current as of November 2026, but department focus, bed counts, and construction status can change over time. This isn’t medical advice. For your child’s specific situation, talk to your Kinderarzt or Hausarzt directly, and for a genuine emergency, call 112 or go to the nearest emergency department rather than relying on this page to decide.
