“…However, transplant recommendations by the adult and pediatric nephrologists (82% vs. 78%) were similar. Additionally, our overall response rate surpasses the mean response rate of 54% for published physician surveys (23). Furthermore, the analyses comparing responders to nonresponders demonstrated no differences in response rate by geographic region.…”

Transplantation is the treatment goal for youth with kidney failure. To assess the effects of compliance, parental education and race on nephrologists' recommendations for transplantation in children, we surveyed a national random sample of adult and pediatric nephrologists. We elicited transplant recommendations for case vignettes created from random combinations of patient age, gender, race, cause of renal failure, family structure, parental education and compliance. Of 519 eligible physicians, 316 (61%) responded. Nephrologists were more likely to recommend transplantation for children of college-educated parents than children of parents who did not finish high school, despite identical clinical and demographic characteristics (adjusted OR 1.48, 95% CI 1.18, 1.86). Patient noncompliance negatively influenced transplant recommendations (adjusted OR 0.1, 95% CI 0.08, 0.13). Additionally, compliance had a different effect on transplant recommendations for white compared with black patients. The adjusted OR of a white, compliant patient being referred for transplantation were twice that of a black compliant patient (OR 2.06, 95% CI 1.17, 3.6). Education and compliance with therapy independently influence nephrologists' recommendations for transplantation in youth with kidney failure. Among the most compliant candidates, referral for transplantation may vary with patient race.

“…7 Although not directly linked to ascertainment rates, response rates are straightforward to measure and are the most common method for assessing the potential for selection bias. 8 Whilst no differences in response rates between ophthalmologists by type of hospital and principal appointment (NHS consultants and other grades) were noted, a variation in regional response rates was evident. Despite this and the positive correlation between card return rates and true case reporting, it remains difficult to estimate the overall effects on ascertainment.…”

“…9 However, some may also feel more comfortable not responding, since their non-response will go undetected. 8 There were no opportunities to issue reminders or replacement questionnaires, which would have increased the response rate, but the response rate achieved was comparable with similar surveys. 8 As there was an overrepresentation of case reporters amongst those who participated in the survey, there may have been an overstating of positive sentiments.…”

We report an evaluation of the British Ophthalmological Surveillance Unit (BOSU), a nationwide active surveillance scheme to assist with the case ascertainment of rare eye conditions. The evaluation assessed participation rates, study applications and research outputs. In addition, through an anonymous postal survey we ascertained the opinions of ophthalmologists regarding the usefulness, levels of feedback, barriers to participation and levels of case ascertainment. Over the first 3 years, the 4-month mean participation rate has improved from 58% to 71%. Ten studies have used this system for case ascertainment. To date three journal publications and 10 conference presentations have reported findings from these studies. It was observed that 582/870 (68%) questionnaires were returned by ophthalmologists, of whom 95% considered BOSU as very or quite useful. In all, 71% reported overall feedback to be sufficient. However, 34% requested greater feedback from research groups. Reported barriers to effective participation were 'having to remember the patient's identity' (52%) and paying for return postage of cards (22%). However, 72% of respondents did not consider the work involved in reporting a case to be prohibitive. Self-reported levels of case ascertainment by ophthalmologists for completed studies ranged between 72% and 95%. This population-based surveillance system provides an effective method for prospective case identification and subsequent data collection. It enables the study of sufficiently representative samples to allow meaningful epidemiological analysis and avoid bias. Its success relies upon the high level of support that it currently receives from ophthalmologists.

“…Although there is a chance of a non-response bias, well-done physician surveys often only achieve response rates of around 50%. [30][31][32][33] The risk strata cut-offs were determined using the 25th percentiles from the distribution of physician responses to satisfy 75% of physicians. Such cut-offs could be insufficient for up to 25% of physicians.…”

Introduction: Five percent of transient ischemic attack (TIA) patients have a subsequent stroke within 7 days. The Canadian TIA Score uses clinical findings to calculate the subsequent stroke risk within 7 days. Our objectives were to assess 1) anticipated use; 2) component face validity; 3) risk strata for stroke within 7 days; and 4) actions required, for a given risk for subsequent stroke. Methods: After a rigorous development process, a survey questionnaire was administered to a random sample of 300 emergency physicians selected from those registered in a national medical directory. The surveys were distributed using a modified Dillman technique. Results: From a total of 271 eligible surveys, we received 131 (48.3%) completed surveys; 96.2% of emergency physicians would use a validated Canadian TIA Score; 8 of 13 components comprising the Canadian TIA Score were rated as Very Important or Important by survey respondents. Risk categories for subsequent stroke were defined as minimalrisk: <1%; low-risk: 1%-4.9%; high-risk 5%-10%; critical-risk: > 10% risk of subsequent stroke within 7 days. Conclusion: A validated Canadian TIA Score will likely be used by emergency physicians. Most components of the TIA Score have high face validity. Risk strata are definable, which may allow physicians to determine immediate actions, based on subsequent stroke risk, in the emergency department.
