The complex logistics of conducting surveys with mobile telephones have been discussed in the literature. This paper outlines the actual challenges encountered during

a recent national sexual Bak apoptosis health survey in Ireland, which utilized a mobile telephone sampling frame to recruit approximately half of the sample.

Method: The 2010 Irish Contraception and Crisis Pregnancy Survey (ICCP-2010) is a nationally representative sample of adults aged 18-45 years living in Ireland (n = 3002; 1416 recruited by landline telephone and 1586 recruited by mobile telephone). The overall response rate for the survey was 69% (79% for the landline telephone strand; 61% for the mobile telephone strand). All interviews were conducted using computer-assisting telephone interviewing.

Results: During the 18-week fieldwork period, five main challenges relating to the use of mobile telephones were encountered: (1) explaining to respondents how random digit dialling works in relation to mobile telephones; (2) establishing the respondent’s eligibility; (3) calling the respondent with the Caller ID blocked or withheld; (4) calling the respondent when they are in any number of locations or situations; and (5) explaining to respondents the importance of refusal conversion calls for the response

rate calculation. Details of how the BMS-754807 survey protocols and procedures were monitored and adapted throughout the study to ensure a high response rate are outlined.

Conclusion: It is undeniably more challenging to recruit respondents using mobile telephones as opposed to landline telephones. Respondents are generally not familiar with being contacted on their personal mobile telephone for the purposes of being recruited for a research study. The main challenge for survey methodologists and interviewers is to Cilengitide supplier devise simple protocols to explain to respondents why they are being contacted on a mobile telephone. Recommendations

for survey researchers interested in using this methodological approach in the future are discussed.”
“BACKGROUND: Global control of the tuberculosis (TB) epidemic remains poor, especially in high-burden settings where ongoing transmission sustains the epidemic. In such settings, a significant amount of transmission takes place outside the household, and practical approaches to understanding transmission at community level are needed.

OBJECTIVE: To identify and map potential TB transmission ‘hot spots’ across high-burden communities.

SETTING AND DESIGN: Our method draws on data that qualitatively describe a high-burden community in Cape Town, South Africa. Established transmission principles arc applied to grade the potential TB transmission risk posed by congregate settings in the community.
