[Accessibility of doctors' surgeries in Essen, Germany]. / Barrierefreiheit von Arztpraxen am Beispiel Essen.

BACKGROUND: Constructional barriers often prevent persons who are only partially able, for example those requiring a wheel chair for pre-ambulation, from entering buildings where doctors practise. Even though many international and national resolutions have long been demanding free access to the environment for the partially able, this has not been specially prescribed in Germany. Hence, no one knows anything about outpatient health care facilities in this regard. The present study aimed at analysing accessibility to orthopaedic and neurological practices and surgeries for wheelchair patients. METHOD: We chose Essen, the sixth largest town in Germany, as an example of an urban area, where orthopaedists and neurologists are frequently accessed by wheelchair patients. We performed on-site investigations of the exterior and interior zones of all orthopaedic and neurological surgery buildings in Essen (each n = 29). Criteria for our descriptive analysis were parking lots for the handicapped, shunting areas, entrances at-grade, steps/stories, banisters, ramps, bells and openers of front, elevator and surgery doors, their opening and width. Following the criteria of the DIN 18 024 standard part 2 ("accessibility") the surgeries were divided into four groups 1) fully accessible; 2) slight barriers; 3) considerable barriers; 4) massive barriers. RESULTS: None of the 58 investigated surgeries was fully accessible, 21 of the 29 surgeries of each medical specialty had massive barriers, so that wheelchair patients could access these surgeries only with the help of at least two (strong) persons. Six of the 29 orthopaedic and three of the 29 neurological surgeries had slight barriers, whereas two orthopaedic and five neurological surgeries had distinct barriers. Main barriers were steps in the entrance area; front, elevator or surgery doors too narrow (width less than 80 cm), and elevators too small. DISCUSSION: For wheelchair patients in Germany, free choice of doctors seems to be massively reduced. Since 80 % of orthopaedic and 90 % of neurological surgeries in Essen do not fulfil the quality feature "constructional accessibility", measures that have been taken in the past to help partially able persons to participate in this respective aspect of social life have not been effective. New measures to improve the present situation should be agreed upon by all the institutions involved (politics, local authorities/construction supervision, sickness funds, doctors and associations of sickness fund physicians, and concerned persons). If voluntary measures do not lead to free choice of doctors for wheelchair patients, further legal regulations appear to be mandatory.

Cardiac troponin I plasma levels for diagnosis and quantitation of perioperative myocardial damage in patients undergoing coronary artery bypass surgery.

OBJECTIVE: The definition of a reliable and generally accepted diagnostic standard for perioperative myocardial damage is desirable. Cardiac troponin I (cTnI) is highly specific for myocardial tissue and can be measured rapidly. The aim of our study was to evaluate the diagnostic potential of cTnI for myocardial lesions in patients undergoing coronary artery bypass surgery (CABG). METHODS: A total of 119 patients with diffuse coronary artery disease were operated on using blood cardioplegia. Serial blood samples drawn before and after surgery were analyzed for the activity of creatine kinase MB isoenzyme (CKMB) and the concentrations of CKMB mass, cardiac troponins T and I. On the basis of the biochemical results (except cTnI) and the findings of electrocardiography/echocardiography, patients were classified and cTnI was studied for each group separately: group I, minor myocardial damage; group II, non-transmural infarction; group III, transmural infarction; and group IV, preoperative non-transmural infarction. RESULTS: In 87 patients of group I (73.1%) cTnI levels remained low; 19 patients (16.0%) were assigned to group II, 8 patients (6.7%) to group III, and 5 patients (4.2%) to group IV. For discrimination of patients without and with perioperative myocardial infarction (PMI) by one cTnI determination, the use of cutoff values of 6.5 ng/ml at 8 h, 9.8 ng/ml at 12 h, and 11.6 ng/ml at 24 h after aortic unclamping resulted in a diagnostic efficiency of 88, 94 and 98%). Especially, a cTnI value at 24 h had a sensitivity of 100% and a specificity of 97%. Cardiac troponin levels at 24 h were found to correlate closely with the well-recognized 2-48 h area-under-the-curve (P < 0.0001; R = 0.993), making serial determinations unnecessary. CONCLUSIONS: cTnI qualifies as a marker for diagnosis of PMI and quantitation of the amount of myocardial damage, because of the availability of a quick diagnostic test with high specificity, the high diagnostic efficiency, and especially the sufficient information gained by a single determination 24 h after aortic unclamping.
