Factors Affecting the Implementation Process of Pertussis [Tdap] Immunization in Pregnant Women in an Italian Region: A Qualitative Study

Developing an Evidence-Based Tool for Planning and Evaluating Vaccination Strategies Aimed at Improving Coverage in Elderly and At-Risk Adult Population

Background: Vaccination coverages need to be constantly maintained and improved with the implementation of vaccination strategies. This paper describes the development of an evidence-based tool to guide their planning and evaluation.

Methods: A scoping review was performed in MEDLINE and institutional websites to search for similar available tools. A first version of the tool was developed considering review results and a four-step method used for the control and continuous improvement of processes and products, namely the Deming cycle. A panel of eight experts was then involved in a Delphi study for the finalization of the tool that was eventually discussed in a face-to-face meeting.

Results: The scoping review found only one document and the first version of the tool was composed of 30 items. After the Delphi first round, 11 additional items were suggested and 5 original items amended. After the Delphi second round 41 items were eventually included. During the face-to-face meeting, 7 items were recognized as requisites for setting vaccination strategies, whereas 17 as relevant ones.

Conclusions: Current public health challenges impose the need for evidence-based tools to organize effective vaccination strategies. Our tool is a first proposal which aims to reflect this focus.

Experience and attitudes on vaccinations recommended during pregnancy: survey on an Italian sample of women and consultant gynecologists

Active immunization in pregnancy is recommended for the influenza and the tetanus, diphtheria, and acellular pertussis (Tdap) vaccines. Evidence indicates vaccine effectiveness in preventing influenza-related hospitalizations and pertussis in early infancy. We investigate vaccine uptake in pregnant and non-pregnant women through a sample of young women and consultant gynecologists, along with the potential predisposing and/or enabling factors affecting attitudes to vaccination (knowledge, beliefs, barriers). A cross-sectional study was conducted between June and September 2019, with a sample of 251 women and 14 consultant gynecologists at the Local Health Authority (ASL01) of the Abruzzo Region (Italy), using an anonymous, self-report questionnaire survey. Among the participants, 5.6% of women had received influenza vaccination, 16.4% had received Tdap during pregnancy and only 1.2% had received both vaccines. The assessment of the psychometric attitudinal variables has suggested a more positive willingness to receive Tdap than influenza vaccine among women, as the former is considered more important for the maternal and neonatal health. Health care workers have reported vaccine safety concerns, lack of information, and misconceptions about the need for vaccination as barriers to immunization in pregnant women. The results of this study will contribute to defining the goals and strategies to increase vaccine uptake under the current recommendations, through promoting effective training programs for all health care workers involved (gynecologists, obstetricians, public health physicians).
