Hamburg Doesn't Have 'The' Children's Hospital. It Has Three, and Each Does Something Different
Hamburg's pediatric hospital landscape has three real anchors, not one, and they aren't substitutes for each other. Altonaer Kinderkrankenhaus (AKK), Bleickenallee 38 in Altona, opened in 1859 and has been an independent subsidiary of Universitätsklinikum Hamburg-Eppendorf (UKE) since 1 September 2006, a link the two organizations cite when describing themselves, combined, as running Germany's largest children's clinic. AKK today runs roughly 242 beds across eleven Fachabteilungen, general pediatrics, neonatology and intensive care, pediatric surgery and urology, trauma surgery, neurosurgery, orthopedics, ENT, anesthesiology, radiology, and psychosomatics, plus a Perinatalzentrum for high-risk newborns, treating around 16,000 inpatient and 45,000 outpatient cases a year. Katholisches Kinderkrankenhaus Wilhelmstift, Liliencronstraße 130 in Rahlstedt, is a separate Catholic-run institution founded in 1925, not part of UKE, and is actually Hamburg's single largest children's hospital by bed count at 261, spread across 11 departments and 22 specialized areas, including a dedicated unit for severely burned children. Its Zentrale Notaufnahme was badly damaged in an August 2024 Starkregen flood, closed for a full rebuild, and was reopened by Hamburg's health senator, Melanie Schlotzhauer, in March 2026 with three separate triage rooms, backed by a roughly six-million-euro equipment grant approved in December 2025. The third anchor, Kinder-UKE, a dedicated pediatric building at Martinistraße 52 in Eppendorf that opened in 2017 with 148 beds, is where Hamburg sends its rarest and most complex pediatric cases, oncology, severe neurological and genetic disease, liver, kidney, and bone marrow transplants, and it runs its own 24-hour children's emergency room in Building O47, separate from both UKE's main adult emergency department and the four Notfallpraxen für Kinder already documented elsewhere on this site. All three accept GKV, PKV, and EU health insurance cards exactly the way Hamburg's Notfallpraxen already do, no upfront payment or referral required for a genuine emergency.
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.
| Institution | Location | Ownership | Beds | Known for | Own 24/7 children's ER? |
|---|---|---|---|---|---|
| Altonaer Kinderkrankenhaus (AKK) | Bleickenallee 38, Altona | UKE subsidiary since 2006 | ~242 | General pediatric surgery, orthopedics, neurosurgery, Perinatalzentrum | Yes |
| Katholisches Kinderkrankenhaus Wilhelmstift | Liliencronstraße 130, Rahlstedt | Independent Catholic gGmbH | 261 | Hamburg's largest children's hospital overall; severe-burns unit | Yes (rebuilt 2024-2026) |
| Kinder-UKE | Martinistraße 52, Building O47, Eppendorf | Part of UKE | 148 | Oncology, rare neurological/genetic disease, transplants | Yes (separate from UKE's main ER) |
- 1 Altonaer Kinderkrankenhaus, Bleickenallee 38, 22763 Hamburg. UKE subsidiary since 1 September 2006, own 24/7 Zentrale Notaufnahme.
- 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 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: One Half of “Germany’s Largest Children’s Clinic”
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 six 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.
What often surprises newcomers is the ownership structure sitting underneath that name. Since 1 September 2006, AKK has operated as a wholly owned subsidiary of Universitätsklinikum Hamburg-Eppendorf, and the two organizations point to that link, combined with the newer Kinder-UKE building described below, when they describe themselves as running Germany’s largest children’s clinic overall. 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 inpatients and 50,000 outpatients a year. 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 health 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, 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.
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

- Genuine emergency, any time: go to the nearest of AKK, Wilhelmstift, or Kinder-UKE, or use the Notfallpraxis networkAll three run their own 24/7 Zentrale Notaufnahme; this site's Kindernotdienst guide covers the separate weekday-evening and weekend Notfallpraxis schedule.
- 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.
- General pediatric surgery, orthopedics, urology, neurosurgery, or trauma: AKK and Wilhelmstift both run full departmentsAsk your Kinderarzt which currently has shorter waits.
- Severe burn specifically: ask for Wilhelmstift's dedicated burns unit by name.
- Bring the Gesundheitskarte and, if you have one, the yellow U-HeftRegardless of which of the three hospitals you're headed to.

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 mid-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.
FAQ & Common Pitfalls
Our Kinderarzt wants to refer our child to a specialist. Which of the three hospitals do we actually ask for?
It depends entirely on what's being treated, not on which hospital is closest. For general pediatric surgery, orthopedics, urology, trauma, or neurosurgery, both Altonaer Kinderkrankenhaus and Wilhelmstift run full departments and either is a reasonable ask, your Kinderarzt will usually already have a preference based on current waitlists. For anything genuinely rare or complex, pediatric oncology, a severe neurological or rare genetic condition, or a liver, kidney, or bone marrow transplant, Kinder-UKE at Martinistraße 52 is where those cases concentrate in Hamburg, and your Kinderarzt's referral letter should name it directly. For a severe burn specifically, ask for Wilhelmstift's dedicated burns unit by name. None of this changes what to do in a genuine emergency, in that case the nearest of the three, or the Notfallpraxis network covered elsewhere on this site, is always the right call.
Is Altonaer Kinderkrankenhaus actually part of UKE, or is it a separate hospital?
Both are true at once, which is exactly why it's worth understanding. AKK has operated its own campus at Bleickenallee 38 in Altona since 1914 and keeps its own name, its own gGmbH structure, and day-to-day independence. But since 1 September 2006 it has been a wholly owned subsidiary of Universitätsklinikum Hamburg-Eppendorf, and the two organizations lean on that link when describing themselves, combined with the newer Kinder-UKE building, as forming Germany's largest children's clinic. In practice, this means a referral or transfer between AKK and Kinder-UKE tends to move more smoothly than a referral to an entirely unrelated hospital would, since both sit inside the same organizational structure even though they occupy different campuses and treat different kinds of cases.
Is Wilhelmstift's emergency department fully working again after the 2024 flood?
Yes. Heavy rainfall in August 2024 badly damaged the Zentrale Notaufnahme at Wilhelmstift, forcing a full closure and rebuild rather than a quick repair. Hamburg's health senator, Melanie Schlotzhauer, officially reopened the modernized department in March 2026, and the rebuild wasn't just a restoration: it introduced three separate triage rooms where patients are assessed on arrival, a structural improvement over what existed before. The city's Krankenhaus-Investitionsprogramm contributed roughly one million euros toward that specific triage upgrade, and a separate roughly six-million-euro grant approved in December 2025 is funding replacement medical equipment, including a new MRI machine and modern ventilators and incubators. If you're relying on older information that describes the ZNA as closed or under construction, it's out of date.
What does Kinder-UKE actually specialize in, and can we just walk in for something ordinary?
Kinder-UKE, the dedicated pediatric building that opened on the UKE campus in 2017, is built around Hamburg's most complex cases: oncology, severe neurological and rare congenital conditions, and liver, kidney, and bone marrow transplants, the kinds of diagnoses that concentrate at a university hospital rather than spreading across every children's hospital in the city. Most families reach it through a referral from a Kinderarzt or a transfer from another hospital once a diagnosis points that way, rather than a routine walk-in visit. That said, it does maintain its own round-the-clock children's emergency room in Building O47, entirely separate from UKE's main adult Zentrale Notaufnahme in Building O10, so a genuine emergency there is treated the same as at AKK or Wilhelmstift. It simply isn't the hospital to default to for an ordinary fever or minor injury when AKK and Wilhelmstift's dedicated Notfallpraxen exist specifically for that.
How is a children's emergency department actually different from a regular hospital's emergency room?
The structural difference is staffing and equipment, not just decor. At all three of AKK, Wilhelmstift, and Kinder-UKE, the doctors and nurses assessing your child are pediatric specialists, not general emergency physicians who occasionally also see children, and dosing, imaging, and monitoring equipment are sized and calibrated for children's bodies rather than adapted from adult equipment. Waiting and treatment areas are physically separate from any adult emergency department on the same campus, and in Germany's system a parent is routinely expected and permitted to stay with their child throughout, rather than being asked to wait outside. None of this changes triage logic: a child is still seen according to how urgent their condition genuinely is, not simply the order they arrived in.
Does it matter which insurance we have for choosing between the three hospitals?
Not for access. All three are established parts of Hamburg's hospital landscape and accept statutory insurance (GKV), private insurance (PKV), and EU health insurance cards for medically necessary treatment, the same as the Notfallpraxis network already documented on this site, no upfront payment and no referral required for a genuine emergency. For a scheduled, non-emergency specialist appointment, a normal Überweisung (referral) from your Kinderarzt or Hausarzt is the standard route regardless of which of the three hospitals you're being sent to, and none of them requires choosing a hospital based on insurance type the way some private clinics elsewhere might.
How does this fit with the 116117 and Notfallpraxen system already covered on this site?
They're the same landscape, viewed from a different angle. The four Notfallpraxen für Kinder, at AKK, Wilhelmstift, Helios Mariahilf, and Asklepios Nord-Heidberg, run on a published weekday-evening and weekend schedule coordinated through Arztruf Hamburg, and that system is covered in detail in this site's Kindernotdienst guide. What that piece doesn't cover is that AKK, Wilhelmstift, and Kinder-UKE each also run their own full, round-the-clock Zentrale Notaufnahme underneath and outside that scheduled Notfallpraxis system, for anything that can't wait, and that Kinder-UKE's emergency room specifically sits entirely outside the official four-Notfallpraxen list, since it belongs to UKE's own separate emergency infrastructure rather than the KVH-coordinated Notfallpraxis network. For a fever at 2am, 116117 is still the right first call either way.
