Overview

Clementinenhaus Hannover, officially the DRK-Krankenhaus Clementinenhaus, is a hospital of basic and standard care (Grund- und Regelversorgung) located in the List district of Hannover, Germany. It is operated by a foundation under civil law (Stiftung des bürgerlichen Rechts) and is closely associated with the German Red Cross (DRK). The hospital has 195 beds and provides a range of medical specialties including general and visceral surgery, orthopedics and trauma surgery, internal medicine with focuses on gastroenterology, geriatrics, and cardiology, as well as anesthesia and intensive care. It also maintains six attending physician departments (Belegabteilungen) and is a recognized training institution for nursing. The institution traces its origins to 1875, when Olga Freifrau von Lützerode founded a nursing sisterhood and the "Krankenpflegerinnen-Anstalt zu Hannover" with her own funds. She named it Clementinenhaus, derived from "clementia dei" (mercy of God). The first hospital building opened in 1887 with 46 beds, funded by donations from notable figures including Florence Nightingale, Wilhelm Busch, Sir Joseph Lister, Kaiser Wilhelm I, and Empress Augusta. Over the decades, the hospital expanded, survived near-total destruction in World War II, and underwent major modernization, including a comprehensive renovation from 2007 to 2011 supported by the state of Lower Saxony. Today, Clementinenhaus positions itself as a small, successful neighborhood hospital (Stadtteilkrankenhaus) guided by Red Cross values of humanity, impartiality, neutrality, independence, voluntary service, unity, and universality. It emphasizes patient-centered care, friendliness, and professional competence, and reinvests all revenues into the hospital, its staff, and ultimately patient care. The hospital is an active teaching hospital and has received quality certifications, including the "Verpflichtung zu Excellence" from the German Society for Quality (DGQ) in 2003 and KTQ certification around 2005.

History

The Clementinenhaus was founded in 1875 by Olga Freifrau von Lützerode, who established a nursing sisterhood and the "Krankenpflegerinnen-Anstalt zu Hannover" with her own funds. The name Clementinenhaus derives from "clementia dei" (mercy of God). Initially located in a rented three-story double house at Eichstraße 16/17 in the Oststadt district, the institution trained nurses for service both within the house and externally. In 1876 the sisterhood was placed under the Red Cross, and in 1882 the nursing institution followed. A "mild foundation" (milde Stiftung) was established in 1882 to further nursing education. In the early 1880s, a plot of land was acquired for a dedicated hospital building. Donations from figures such as Florence Nightingale, Wilhelm Busch, Sir Joseph Lister, Kaiser Wilhelm I, and Empress Augusta enabled construction. The foundation stone was laid in 1885, and the hospital opened in 1887 with 46 beds. In 1898, Empress Augusta inaugurated a retirement home for retired sisters on land donated by the city of Hannover. By 1900, the nursing school was expanded and received state recognition, and the street "Am Clementinenhaus" was renamed "Lützerodestraße" in honor of Olga von Lützerode on the sisterhood's 25th anniversary. During World War I, the Clementinenhaus served as a military hospital of the Vaterländischer Frauenverein with 100 beds, and 67 sisters were deployed on the Western and Eastern fronts, particularly in Constantinople and hospital trains. In 1933, the hospital acquired the adjacent property on Edenstraße for expansion. In 1935 it was assigned to the DRK sisterhood in Berlin, and in 1937 subordinated to an office that took over all assets. At that time the hospital had 150 beds. During World War II, 200 sisters served in the Wehrmacht medical service, and the Clementinenhaus was partly a military hospital. In March 1945, air raids on Hannover nearly completely destroyed the hospital, leaving only a few beds operational. Reconstruction began in autumn 1945, with the hospital and nurses' home rebuilt by 1948. In 1951, the foundation "DRK-Clementinenhaus – Krankenpflegerinnenanstalt für das Land Niedersachsen" was established, with a board of trustees (Kuratorium) as its governing body. In the early 1960s, the hospital was expanded with a new bed wing, increasing capacity to 250 beds. In 1976 it was renamed DRK-Krankenhaus Clementinenhaus. In 1977, the DRK sisterhood merged with the Cornelien-Schwesternschaft Hameln. In the late 1980s, intensive care received modern facilities in an extension. In the early 1990s, a left heart catheterization laboratory was installed, and in 1997 a CT scanner went into operation. Radiology was outsourced to a cooperation partner. In 1999, the emergency department was reorganized into a "Central Patient Admission" (ZPA). In 2003, the DRK-Krankenhaus Clementinenhaus was the first hospital in Germany to receive the "Verpflichtung zu Excellence" certificate from the German Society for Quality (DGQ) for its medical and nursing services. In 2004, the two attending physician clinics Klinik Dr. Boueke and Bertaklinik were integrated. Around 2005, the hospital received KTQ certification. On 3 July 2006, the foundation stone was laid for a comprehensive renovation and modernization project supported by the state of Lower Saxony with 24.5 million euros. The construction work took place from 2007 to 2011 while the hospital remained in operation. Around 2010, the renovated intensive care unit and newly built operating area opened. The renovation was completed on 1 January 2012. Two years later, the geriatrics department was expanded with a modern therapy wing. In 2014, a member of the sisterhood was deployed during the Ebola epidemic in Sierra Leone.
