[Medial femoral neck fractures: possible reasons for delayed surgery. Part 2: Results of data from external inpatient quality assurance within the framework of secondary data evaluation]. / Mediale Schenkelhalsfraktur: mögliche Gründe für eine verzögerte operative Versorgung. Teil 2: Ergebnisse der Daten der externen stationären Qualitätssicherung im Rahmen sekundärer Datennutzung.

PROBLEM: In Germany a disproportionate number of patients with a femoral neck fracture still experience a delay in surgery. In 2008 delays of more than 48 h after admission occurred for 15.4 % of patients. This leads to increases in surgical and general complications as well as pressure sores. OBJECTIVE: Possible reasons that lead to delayed operations were investigated in a nationwide study. DATA AND METHODS: Using nationwide data from the German inpatient external quality assurance program from the year 2008 the reasons for performing operations later than 48 h after hospital admission were examined both exploratory and analytically using a multiple logistic regression model considering combined effects. RESULTS: Surgery was more frequently delayed for patients who were admitted to hospital on Friday or Saturday, patients with a higher American Society of Anesthesiologists (ASA) classification, men, patients with malignant diseases, in the presence of infectious diseases and patients with heart disease. Operations carried out within the first 48 h were more frequent with displaced fractures and in the presence of hypertension or mental illness. The volume per hospital had no consistent effect on the time delay of surgery. During the week no significant differences between the departments were detected. On Friday or Saturday surgery was delayed more often when patients were admitted to a department of general surgery than to a department of trauma surgery or orthopedics. CONCLUSIONS: There are medical and non-medical reasons for delayed surgery of femoral neck fractures. Studies have confirmed that delayed surgery for femoral neck fracture harms the patients. Organizational reasons which prevent an immediate operation, e.g. admission on Friday or Saturday, should therefore be eliminated by improvements in hospital organization and staffing. These can be measures of individual hospitals or of several hospitals in cooperation. The target should be to ensure a comprehensive and timely provision of the highest quality care even at the weekend.

[Are hospital administrative data suitable for external quality assurance? Comparison of quality indicators based on separate statutory data collections (BQS) and hospital administrative data]. / Krankenhaus-Routinedaten zur externen Qualitätssicherung? Vergleich von Qualitätsindikatoren anhand der Daten der gesetzlichen externen Qualitätssicherung (BQS) und Routinedaten.

BACKGROUND: German hospitals are obliged legally to provide clinical data for external comparative quality assurance. Data rely on administrative data and just as on additional data collections for this purpose only. They are used to identify defined quality indicators (so-called BQS data). The Agency for Healthcare Research and Quality (AHRQ) also developed quality indicators that rely on hospital administrative data to evaluate the quality of inpatient care. METHODS: Six selected quality indicators were computed by both methods. 2007 data from the nationwide external quality assurance program were analyzed and compared to quality information derived from a 2007 10 % nationwide sample of administrative hospital data. RESULTS: Regarding the indicators "Obstetric trauma", "Mortality of community acquired pneumonia", "Postoperative deep vein thrombosis" and "Postoperative pulmonary embolism" rates are significantly higher in hospital administrative data than in BQS data (p < 0.01). Inversely, rates of the indicator "Decubitus ulcer" are significantly lower (p < 0.001). CONCLUSION: Possible causes for the results might be divergent motivations for data collection or restrictions in data collection. It remains unclear which method properly reflects the true status. Selected indicators (e. g. obstetric trauma), however, are suitable to be substituted by hospital administrative data.

[Determining the indication for primary total hip and knee replacement. Results of external quality assurance of over 270,000 primary total hip and knee replacements]. / Indikationsstellung in der primären Hüft- und Kniegelenkendoprothetik. Ergebnisse der externen Qualitätssicherung von über 270.000 primären Hüft- und Kniegelenkendoprothesen.

BACKGROUND: The German mandatory quality assurance programme collects data from all primary total hip and knee replacements. The quality of the indication is measured by clinical and radiological criteria. The results were analysed in terms of differences in establishing the indication subject to patient and hospital characteristics. MATERIALS AND METHODS: Data on more than 270,000 primary total hip and knee replacements that were operated in 2006 in Germany were analysed concerning differences in the quality of the indication subject to age, gender, hospital volume and density of population and hospitals (metropolitan vs rural areas). The statistical analysis was done by exact Fisher's test. RESULTS: The quality of the indication was statistically significantly better in men, patients 60 and older, in rural areas and in high volume hospitals (50 and more joint replacements per year). DISCUSSION: Data of this mandatory German quality assurance programme are useful to describe differences in medical care. The results are valid and complete. An exact analysis of the reasons for these differences is difficult though. Data focus is on quality assurance and represent only in-hospital results. CONCLUSION: Further analyses are necessary to ascertain whether the differences in quality of care are deficits or only variances in medical care.
