OBJECTIVE: To evaluate the interpretive performance and inter-observer agreement on digital mammographs among radiologists and to investigate whether radiologist characteristics affect performance and agreement. MATERIALS AND METHODS: The test sets consisted of full-field digital mammograms and contained 12 cancer cases among 1000 total cases. Twelve radiologists independently interpreted all mammograms. Performance indicators included the recall rate, cancer detection rate (CDR), positive predictive value (PPV), sensitivity, specificity, false positive rate (FPR), and area under the receiver operating characteristic curve (AUC). Inter-radiologist agreement was measured. The reporting radiologist characteristics included number of years of experience interpreting mammography, fellowship training in breast imaging, and annual volume of mammography interpretation. RESULTS: The mean and range of interpretive performance were as follows: recall rate, 7.5% (3.3–10.2%); CDR, 10.6 (8.0–12.0 per 1000 examinations); PPV, 15.9% (8.8–33.3%); sensitivity, 88.2% (66.7–100%); specificity, 93.5% (90.6–97.8%); FPR, 6.5% (2.2–9.4%); and AUC, 0.93 (0.82–0.99). Radiologists who annually interpreted more than 3000 screening mammograms tended to exhibit higher CDRs and sensitivities than those who interpreted fewer than 3000 mammograms (p = 0.064). The inter-radiologist agreement showed a percent agreement of 77.2–88.8% and a kappa value of 0.27–0.34. Radiologist characteristics did not affect agreement. CONCLUSION: The interpretative performance of the radiologists fulfilled the mammography screening goal of the American College of Radiology, although there was inter-observer variability. Radiologists who interpreted more than 3000 screening mammograms annually tended to perform better than radiologists who did not.

Medical Device Single Audit Program is one of the key projects in International Medical Device Regulators Forum, which has much experience to be used for reference. This paper briefly describes the procedures and contents of the Witnessed Audit in Medical Device Single Audit Program. Some revelations about the work of Witnessed Audit have been discussed, for reference by the Regulatory Authorities and the Auditing Organizations.

The audit of the quality management system in the medical device single audit program covers the requirements of several national regulatory authorities, which has a very important reference value. This paper briefly described the procedures and contents of this audit. Some enlightenment on supervision and inspection are discussed in China, for reference by the regulatory authorities and auditing organizations.

Since breast ultrasonography (US) has been used as an adjunctive screening modality in women with dense breasts, the need has arisen to evaluate and monitor its possible harm and benefits in comparison with other screening modalities such as mammography. Recently, the fifth edition of the Breast Imaging Reporting and Data System published by the American College of Radiology has suggested auditing methods for screening breast US. However, the method proposed therein is slightly different from how diagnostic performance was calculated in previous studies on screening breast US. In this article, the background and core aspects of medical audits of breast cancer screening will be reviewed to provide an introduction to the medical auditing of screening breast US, with the goal of helping radiologists to understand and identify potential ways to improve outcomes.

BACKGROUND: Skin cancer is the most prevalent cancer by organ type and referral accuracy is vital for diagnosis and management. The British Association of Dermatologists (BAD) and literature highlight the importance of accurate skin lesion examination, diagnosis and educationally-relevant studies. METHODS: We undertook a review of the relevant literature, a national audit of skin lesion description standards and a study of speciality training influences on these descriptions. Questionnaires (n=200), with pictures of a circular and an oval lesion, were distributed to UK dermatology/plastic surgery consultants and speciality trainees (ST), general practitioners (GP), and medical students (MS). The following variables were analysed against a pre-defined 95% inclusion accuracy standard: site, shape, size, skin/colour, and presence of associated scars. RESULTS: There were 250 lesion descriptions provided by 125 consultants, STs, GPs, and MSs. Inclusion accuracy was greatest for consultants over STs (80% vs. 68%; P<0.001), GPs (57%) and MSs (46%) (P<0.0001), for STs over GPs (P<0.010) and MSs (P<0.0001) and for GPs over MSs (P<0.010), all falling below audit standard. Size description accuracy sub-analysis according to circular/oval dimensions was as follows: consultants (94%), GPs (80%), STs (73%), MSs (37%), with the most common error implying a quadrilateral shape (66%). Addressing BAD guidelines and published requirements for more empirical performance data to improve teaching methods, we performed a national audit and studied skin lesion descriptions. To improve diagnostic and referral accuracy for patients, healthcare professionals must strive towards accuracy (a circle is not a square). CONCLUSIONS: We provide supportive evidence that increased speciality training improves this process and propose that greater focus is placed on such training early on during medical training, and maintained throughout clinical practice.

INTRODUCTIONThis study evaluated the efficacy of tinnitus retraining therapy (TRT) in habituating patients with tinnitus.

MATERIALS AND METHODSThis is a retrospective review of patients who underwent TRT in a tertiary referral Otorhinolaryngology unit. Patients were followed up with structured interviews with the aid of questionnaire forms. Habituation following TRT was evaluated.

RESULTSA total of 702 patients were included (55% male, 45% female). Habituation of reaction to tinnitus and habituation of perception were analysed. Average duration of follow up was 33 months. In total, 68% of patients described improvement in annoyance following TRT. Of these patients, 80% of them described habituation of perception as well. There was no statistical difference in gender and age between patients who did and did not respond to TRT. However, duration of treatment was significantly longer in patients who habituated (P <0.05). Patients who adopted treatment strategies recommended based on Jastreboff's TRT categories were also found to have higher success rates compared to those who refused.

CONCLUSIONThe goal of TRT is to achieve habituation of reaction to tinnitus. Habituation of perception is often a secondary result of sufficiently habituated response. From our study, more than two thirds of patients with tinnitus achieved habituation of reaction and of these, the majority also habituated to awareness of the tinnitus.

INTRODUCTIONOtorrhoea is a common complaint in Ear, Nose and Throat clinics. This study aimed to establish the pathogens involved in cases of otorrhoea in Singapore, their sensitivity patterns and the effectiveness of empirical management.

METHODSA retrospective chart review was conducted on 91 patients with otorrhoea who had undergone swab cultures between July 2010 and February 2011.

RESULTSOf the 91 cases, 53% were diagnosed empirically as bacterial otitis externa and 25% as otomycosis. Aerobic bacteria accounted for 35.8% of the microorganisms cultured, while 34.7% were fungi and 29.5% were anaerobic bacteria. Pseudomonas (P.) aeruginosa and Staphylococcus (S.) aureus made up 31.6% and 21.0% of the microorganisms, respectively. 20% of S. aureus grown was methicillin-resistant. Aspergillus was the most common fungus and 19% of cultures were polymicrobial. 38% of patients had their treatment changed on the basis of culture results, as no improvement was observed on follow-up. P. aeruginosa was sensitive to ciprofloxacin and gentamicin in 81.8% and 76.0% of patients, respectively, while S. aureus was sensitive to cloxacillin in 93.8% and clindamycin in 87.5% of patients.

CONCLUSIONThe common microorganisms involved in otorrhoea in Singapore are P. aeruginosa, Aspergillus and S. aureus. Resistant strains of Pseudomonas spp. are now present. Methicillin-resistant S. aureus is increasingly prevalent and highly sensitive to vancomycin. Aminoglycoside and fluoroquinolone-containing eardrops are suitable first-line topical antimicrobials. Cloxacillin may be started should a concomitant oral antimicrobial be warranted empirically or for S. aureus infections. Otomycosis should be considered in patients who show no improvement with antibiotics.
