Ethics approval and consent to participate
: The current study is based on an analysis of existing public domain survey dataset that is freely available online with all identifier information detached. The original TSPA survey was approved by Tanzania’s National Institute for Medical Research (NIMR), the Zanzibar Medical Ethics and Research Committee (ZAMREC) and the Institutional Review Board of ICF International in the USA. Therefore, the ethical approval for the current study analysis was automatically deemed unnecessary. Otherwise, the informed consent was requested and obtained from the manager, the person-in-charge of the facility, or the most senior health worker responsible for client services who was present at the facility. All relevant aspects of the study, including its aim and interview procedures were explained clearly to the respondents before interviews. Those respondents agreed their facilities to participate in the study, provided a signed written informed consent.
