[Perioperative mortality in otorhinolaryngology tumor surgery]. / Perioperative Mortalität in der HNO-Tumorchirurgie.

BACKGROUND: Perioperative mortality is an important factor for quality assurance in surgery. For ENT-surgery only sparse data has been published. PATIENTS AND METHODS: A retrospective analysis of 1054 interventions performed on 775 consecutive patients treated surgically for benign and malignant tumors of the head and neck was conducted during a 3-year period in 1995-1998. RESULTS: Of these patients, 34.1% were female and 65.9% male. Age ranged from 4-88 years with a mean age of 54.8 years. 489 patients (63.1%) were treated for malignoma and 286 for benign tumors (36.9%). 0.9% (n = 7) of our patients (n = 775) died during the first 30 days after surgery. That means 0.66% of all surgical interventions (n = 1054) were followed by post-operative mortality. DISCUSSION: In otorhinolaryngological surgery, post-operative mortality seems to be acceptable and low compared to other medical disciplines. The challenge for surgery must be to reach and preserve low perioperative mortality rates in the future. Finding the individually correct indication for surgical treatment must be guaranteed in order to reach this aim.

[Quality assurance indicators in an ENT practice]. / Qualitätsbewertende Indikatoren in einer HNO-Klinik.

BACKGROUND: According to German legislature, hospitals have to implement quality assurance (QA) programs, which are of particular importance in times of ongoing structural changes in healthcare. Amongst other internal methods of QA, indicators measuring the quality of total hospital performance can reflect medical outcome and the activities of physicians, nurses, and administrators. METHODS: Five indicators for measuring total hospital performance and for controlling total medical outcome were used in this study. RESULTS: Evaluation was time consuming, and some indicators showed a wide range, which could be explained by external reasons independent from internal quality. Valid values could be ascertained in the field of administrative quality, whereas in contrast the assessment of medical quality seemed to be more difficult. CONCLUSION: Due to current developments in German healthcare, the application of quality assurance methods such as the presented system of indicators is recommended.

[Indicators for quality evaluation of inpatient patient care in an ENT clinic]. / Qualitätsbewertende Indikatoren in der stationären Versorgung einer HNO-Klinik.

According to the law (Section 137 SGBV) in Germany, hospitals have to implement quality-assurance (QA) programs, which are now of particular importance in times of ongoing structural change in health care. External as well as internal methods of QA are well established and can serve as parameters for single processes and outcomes in most cases. However, there is still an urgent need for methods measuring the quality of total hospital performance. Indicators are powerful instruments for this purpose. They reliably reflect clinical outcome, physicians' and nurses' activities, administration and can be regarded as instruments for general hospital performance in otorhinolaryngology. We describe the process of definition, development and application of quality indicators for measuring quality in health care. Furthermore, we present a critical overview of selected indicators in otorhinolaryngology, general medical indicators and indicators concerning administrative problems. Because of current developments in German health care the application of quality assurance methods similar to the system of indicators presented is strongly recommended.

Onset of action, effectiveness and tolerance of levocabastine and nedocromil in topical therapy of seasonal allergic rhinoconjunctivitis. The Deutsche Rhinitis-Studiengruppe.

This study evaluated the effectiviness and the onset of action of levocabastine (CAS 79547-78-7) nasal spray and eyedrops as well as of nedocromil (CAS 69049-74-7) nasal spray and eyedrops in practical relevant circumstances. The study was designed as an open observational study with parallel groups in 10 centres and comprised 102 patients. All patients presented with seasonal allergic rhinitis and evidenced conjunctival symptoms requiring therapy. The patients as well as the investigators were required to rate the symptoms using symptom scores in order to evaluate the effectiveness of the used drugs. The effectiveness according to symptom scores did not differ significantly between investigator's and patient's judgment. Onset of action was within the first hour in 81.6% of the patients treated with levocabastine and in 82.9% of the patients treated with nedocromil. Symptoms were evaluated on a visual analogue scale ranging from 0 to 100. The use of both substances reduced the severity of the reported symptoms by 50% within the first hour. Thus, no significant difference in the onset of action could be observed even though a later onset of action was expected of the stabiliser of mast cell membranes. Both drugs were tolerated well.
