How are childhood thyroid nodules discovered: opportunities for improving early detection.

In a retrospective analysis of childhood thyroid nodules, 18% were radiographic incidentalomas and 41% were discovered by a clinician's palpation; 40% were discovered by patients' families. The latter group had the largest nodules and highest rates of thyroid cancer metastasis, suggesting opportunities for earlier detection through annual well-child visits.

Does professional orientation predict ethical sensitivities? Attitudes of paediatric and obstetric specialists toward fetuses, pregnant women and pregnancy termination.

BACKGROUND: To determine (1) whether fetal care paediatric (FCP) and maternal-fetal medicine (MFM) specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and (2) whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care. METHODS: Mail survey of 434 MFM and FCP specialists (response rates 60.9% and 54.2%, respectively). RESULTS: MFMs were more likely than FCPs to disagree with these statements (all p values<0.005): (1) 'the presence of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-78.4% vs 63.5%); (2) 'the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-80.5% vs 70.2%); and (3) 'the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-73.5% vs 55.9%). 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being (p<0.01). Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes. CONCLUSIONS: Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

Telephone follow-up to a mail survey: when to offer an interview compared to a reminder call.

BACKGROUND: Using a different mode of contact on the final follow-up to survey non-respondents is an identified strategy to increase response rates. This study was designed to determine if a reminder phone call or a phone interview as a final mode of contact to a mailed survey works better to increase response rates and which strategy is more cost effective. METHODS: A randomized study was embedded within a survey study of individuals treated with ulcerative colitis conducted in March 2009 in Olmsted County, Minnesota. After two mail contacts, non-respondents were randomly assigned to either a reminder telephone call or a telephone interview. Average cost per completed interview and response rates were compared between the two experimental conditions. RESULTS: The response rate in the reminder group and the interview did not differ where we considered both a completed survey and a signed form a complete (24% vs. 29%, p = 0.08). However, if such a signed form was not required, there was a substantial advantage to completing the interview over the phone (24% vs. 43%, p < 0.0001). The reminder group on average cost $27.00 per completed survey, while the interview group on average cost $53.00 per completed survey when a signed form was required and $36.00 per complete when a signed form was not required. CONCLUSIONS: The additional cost of completing an interview is worth it when an additional signed form is not required of the respondent. However, when such a signed form is required, offering an interview instead of a reminder phone call as a follow up to non-respondents does not increase response rates enough to outweigh the additional costs.

Getting physicians to open the survey: little evidence that an envelope teaser increases response rates.

BACKGROUND: Physician surveys are an important tool to assess attitudes, beliefs and self-reported behaviors of this policy relevant group. In order for a physician to respond to a mailed survey, they must first open the envelope. While there is some evidence that package elements can impact physician response rates, the impact of an envelope teaser is unknown. Here we assess this by testing the impact of adding a brightly colored "$25 incentive" sticker to the outside of an envelope on response rates and nonresponse bias in a survey of physicians. METHODS: In the second mailing of a survey assessing physicians' moral beliefs and views on controversial health care topics, initial nonrespondents were randomly assigned to receive a survey in an envelope with a colored "$25 incentive" sticker (teaser group) or an envelope without a sticker (control group). Response rates were compared between the teaser and control groups overall and by age, gender, region of the United States, specialty and years in practice. Nonresponse bias was assessed by comparing the demographic composition of the respondents to the nonrespondents in the experimental and control condition. RESULTS: No significant differences in response rates were observed between the experimental and control conditions overall (p = 0.38) or after stratifying by age, gender, region, or practice type. Within the teaser condition, there was some variation in response rate by years since graduation. There was no independent effect of the teaser on response when simultaneously controlling for demographic characteristics (OR = 0.875, p = 0.4112). CONCLUSIONS: Neither response rates nor nonresponse bias were impacted by the use of an envelope teaser in a survey of physicians in the United States.

Predictors of optional immunization uptake in an urban south Indian population.

BACKGROUND: In Tamil Nadu, India, bacille Calmette-Guérin, diphtheria-tetanus-pertussis, oral poliomyelitis, hepatitis B, and measles vaccines are part of the routine immunization schedule and are available free from government health centers. All other vaccines are optional and available in the private sector at a cost to families. This study assesses immunization rates of routine and optional vaccines and examines parental attitudes toward vaccines in Pallavapuram, Tamil Nadu. METHODS: The cluster sampling method was used to estimate immunization coverage. Seven children 18 to 36 months old were selected from 30 clusters for a total sample of 210 children. Demographics and vaccination data were collected from interviews and immunization records. Predictors of vaccination status were identified with logistic regression models. In addition, 21 parents participated in semi-structured interviews regarding their attitudes toward vaccination. Interviews were analyzed qualitatively for themes. RESULTS: Eighty one percent of children were fully immunized with routine vaccines. However, only 21% received all "major" optional vaccines, defined as 3 doses of Haemophilus influenzae type b vaccine, one dose of measles, mumps, rubella vaccine, and one dose of varicella zoster virus vaccine. Birth in a private hospital (OR 5.6, 95% CI 1.3 to 22.9, P<0.01), higher income (P=0.03), and maternal completion of high school (OR 6.4, 95% CI 1.5 to 27.6, P<0.01) were significant predictors of receiving all major optional vaccines. Elucidated themes from interviews included (1) strong parental support for immunizations, (2) low concern for side effects, and (3) low uptake of optional vaccines due to high cost and lack of awareness. CONCLUSIONS: Coverage of optional vaccines is low despite positive attitudes toward immunizations. Efforts to reduce cost and increase awareness of these vaccines particularly among low-income families or to include these vaccines in the routine schedule may increase uptake and reduce morbidity and mortality from vaccine-preventable diseases.

Differing attitudes toward fetal care by pediatric and maternal-fetal medicine specialists.

OBJECTIVES: The expansion of pediatric-based fetal care raises questions regarding pediatric specialists' involvement in pregnancies when maternal conditions may affect pediatric outcomes. For several such conditions, we compared pediatric and obstetric specialists' attitudes regarding whether and when pediatrics consultation should be offered and their views about seeking court authorization to override maternal refusal of physician recommendations. METHODS: We used a mail survey of 434 maternal-fetal medicine specialists (MFMs) and fetal care pediatric specialists (FCPs) (response rate: MFM, 60.9%; FCP, 54.2%). RESULTS: FCPs were more likely than MFMs to indicate that pediatric counseling should occur before decisions regarding continuing or interrupting pregnancies complicated by maternal alcohol abuse (FCP versus MFM: 63% vs 36%), cocaine abuse (FCP versus MFM: 60% vs 32%), use of seizure medications (FCP versus MFM: 62% vs 33%), and diabetes (FCP versus MFM: 56% vs 27%) (all P < .001). For all conditions, MFMs were more than twice as likely as FCPs to think that no pediatric specialist consultation was ever necessary. FCPs were more likely to agree that seeking court interventions was appropriate for maternal refusal to enter a program to discontinue cocaine use (FCP versus MFM: 72% vs 33%), refusal of azidothymidine to prevent perinatal HIV transmission (80% vs 41%), and refusal of percutaneous transfusion for fetal anemia (62% vs 28%) (all P < .001). CONCLUSIONS: Pediatric and obstetric specialists differ considerably regarding pediatric specialists' role in prenatal care for maternal conditions, and regarding whether to seek judicial intervention for maternal refusal of recommended treatment.
