Understanding Primary Care Physician Vaccination Behaviour: A Systematic Review

BACKGROUND

Vaccine hesitancy decreases adult vaccination coverage and has been recognized by WHO as a major health threat. Primary care physicians (PCP) play a key role in vaccination by giving vaccine counselling to their patients. The aim of this systematic review is to identify the knowledge, beliefs, attitudes and barriers (KBAB) associated with own vaccination and patient recommendation in primary care physicians.

METHODS

MEDLINE/PubMed, EMBASE and Cochrane Library databases were used to search and identify relevant studies based on their title and abstract. In the next step, the full text of each previously selected article was read for eligibility. Articles were selected by two independent reviewers and data extraction was performed using tables. The following information was extracted: methodological characteristics, demographic factors, professional characteristics, and intrinsic or extrinsic factors influencing vaccination or recommendation.

RESULTS

Our search yielded 41 eligible papers, data-sources, previous practices, belief in the effectiveness or safety of the vaccine, perceived risk, and trust in health authorities were all shown to be related to own vaccination and patient recommendation.

CONCLUSION

Internet is the main source of information for PCP related to vaccine hesitancy. It is therefore essential to increase the presence and access to pro-vaccination content in this area. In addition, involving PCP in the establishment of vaccination recommendations could improve their credibility in the institutions. On the other hand, training in communication skills and establishing reminder systems could reflect higher vaccination coverage among their patients.

Trends in the Utilization of Human Papillomavirus Vaccines and the Incidence of Malignant Cervical Cancer in Women and Teenagers: A Secondary Analysis

Background: Human papillomavirus (HPV) is a sexually transmitted infection, and HPV types 16 and 18 are responsible for approximately 66% of all U.S. cervical cancer cases in women. The quadrivalent HPV vaccine was licensed in mid-2006, and it was designed to target and protect against HPV types 6, 11, 16, and 18. The aim of this study is to examine the utilization rate of the HPV vaccine, and the trends and incidence rate of malignant cervical cancer across the United States. Methods: This study utilized data from Surveillance, Epidemiology, and End Results (SEER) and the National Immunization Survey’s (NIS) teenage datasets across select years. For the SEER survey, the modification for confidence intervals by Tiwari et al., 2006, was utilized to obtain the incidence rate per 100,000, so that it could be age-adjusted for the 2000 U.S. standard population, as noted in the data provided by the U.S. Census. The dates examined started in the year 2000 and ended in 2017. For the NIS-Teen survey, the public-use data file was used, and a point estimate (%), with a 95% confidence interval, was performed to examine the trends in HPV vaccine utilization across the U.S. adolescent female population from the years 2007 to 2019. Results: This study found that the rate of diagnosis had been falling over the nearly two decades examined in this study. Implications: This study would support current efforts to encourage the utilization of HPV vaccines that are currently in the vaccination schedule rotation, and to illustrate the importance of completing all doses of the three-step series.
