Comparative assessment of digital and analog radiography: diagnostic accuracy, cost analysis and quality of care.

OBJECTIVE: The aim of this study was to compare digital and conventional radiography for diagnostic accuracy, direct costs, and quality of care. MATERIALS AND METHODS: Diagnostic accuracy was assessed by a critical review of the literature on sensitivity, specificity and ROC analysis of these imaging techniques and by a survey with a panel of radiologists. Direct costs and quality of care were evaluated with a before/after study of the implementation of digital radiography in a Department of Radiology in 'Hospices Civils de Lyon' (France). We included 292 patients and measured duration of examinations and direct costs of equipment, films, maintenance and depreciation. To evaluate any changes in working conditions and patient management, a questionnaire was filled out by the staff of the department. RESULTS: Diagnostic accuracy with digital radiography was equivalent to that of conventional radiography but there were wide variations depending on the type of examination. In 1993, although digital radiography resulted in savings of FF 18,000 including tax (US$ 3600) on film consumption for 1 year of examinations, there was a global additional cost of FF 253,000 (US$ 50,600) for maintenance and depreciation. Results showed a nonsignificant tendency to reduced procedure times for all examinations. Working conditions improved, including greater availability for the patient, improved safety, and increased job interest. CONCLUSION: Digital radiography can be introduced into a large hospital to improve patient and staff conditions, at a higher cost than analog radiography, and depending on the type of examinations performed by the radiology department.

[Quality of medical records in oncology: results of an audit of the Lyon Civil Hospices]. / Qualité des dossiers de cancérologie: résultats d'une démarche qualité aux hospices civils de Lyon.

The objective of this study was to assess the quality of information contained in the medical files of patients in an oncology unit of the Lyons Civil Hospices. Prior to the audit, the health care teams established a set of consensus standards to compare with observed procedures. The analysis of the results led to propositions for guidelines designed to improve points where significant deviations were observed. In the first audit, 80 medical files from patients cared for in four oncology units were retrospectively analysed to determine information quality. Seven items of this audit were retained for a second audit on 127 medical files of patients in a cancerology unit; those items were: postal code of birth place, weight, codified evaluation of general status, TNM classification, pTNM classification, presence of pathology report, localisation of metastasis. Significant deviations were observed for pTNM classification and postal code of birth. During the second audit, a manual of procedures was distributed in the unit, and a new evaluation will be done in one year to assess the impact of guidelines.

[Evaluation of the hospital management of insulin-dependent diabetics]. / Evaluation de la prise en charge hospitalière des patients diabétiques insulino-dépendants.

OBJECTIVE: There is a known relationship between blood glucose control and development or progression of complications in diabetes mellitus. The aim of our study was to assess the quality of hospital care in patients with insulin-dependent diabetes. PATIENTS AND METHODS: A prospective study was conducted over a 6-month period (April 95-September 95) to perform a clinical audit comparing results obtained with care standards. The study group included 257 consecutive patients (age range 15-39 years) who consulted the hospital outpatient clinic of were hospitalized for insulin-dependent diabetes mellitus RESULTS: Results differed depending on the care standards used for comparison. There were 45 patients (17%) who consulted 4 times or more; 43% of the patients were not hospitalized and 32% did not had a fundus examination during the preceding year. There was a 51% deviation from the standard number of capillary blood glucose measurements and 72% of the patients stated they adapted their insulin dose. Mean glycosylated hemoglobin level (HPLC method) was 9.78 +/- 2.37% (standard = 7%). CONCLUSION: This assessment of hospital care demonstrated a deviation of medical surveillance from standard care. More frequent consultations would help improve patient information. It is important to recall that an annual hospitalization and rigorous application of clinical surveillance with annual fundus examination are essential. Information provided by physicians, nurses and dietitians should be an integral part of hospital care. Likewise, it is undoubtedly useful to provide psychological counselling for diabetic patients. A reassessment should evaluate the impact of such recommendations in order to determine the impact, in terms of reduced mortality, of improved hospital care.

[Audit on the quality of medical records in oncology at the Lyon civic hospices]. / Audit de la qualité des dossiers de cancérologie aux Hospices Civils de Lyon.

OBJECTIVE: Assess the quality of information contained in the medical files of patients with cancer pathology. PATIENTS AND METHODS: Eighty medical files from patients cared for in the cancerology units of the Lyons civil hospices were retrospectively analyzed to determine information quality. Prior to the audit, the health care teams established a set of consensus standards to compared with observed procedures. After data collection and analysis of the results, observed departures from the standards led to propositions for guidelines designed to improve points where significant deviations were observed. RESULTS: For certain items, the medical files did not always contain the expected data. Significant deviations were observed for important data such as postal code of birth, pTNM classification, presence of pathology report, codified evaluation of general status. CONCLUSION: Management of these patients requires more rigorous record keeping and classing of appropriate data. A unique data sheet is proposed for all cancer. This should be a computerized sheet with a cancerology reference in each medical unit.

[Evaluation of information for renal insufficiency patients before dialysis]. / Evaluation de l'information aux patients insuffisants rénaux avant dialyse.

The aim of this audit was to assess the quality of information given to patients before dialysis and to improve the use of this information on the acceptability of the treatment. Methods were those used in medical audit: retrospective data collection in a sample of patients, comparison to a set of standards given by professionals and recommendations disseminated in the group of professionals. Results showed that patients received a partial information on the various techniques used in dialysis. More complete information is needed. Recommendations consisted in a specialised team giving a detailed information on the disease and the techniques used in dialysis, with a psychological assistance. After implementation of this team, re-assessment showed a consistent benefit of structured information and entailed the necessity to improve the process of information delivery by general practitioners and specialists.
