Cross-sectional study on vaccination coverage in newly diagnosed HIV-infected persons in the Czech Republic

Factors Associated with Vaccination Adequacy in People Living with HIV: A Cross-Sectional Study

People living with HIV (PLHIV) are at greater risk of illness and death from vaccine-preventable diseases. This study aimed to identify the predictors associated with the recommended vaccination schedule for this group. This was a single-center cross-sectional study conducted in a large Brazilian municipality, evaluating the vaccination statuses of 645 PLHIV for nine immunizers. The primary outcome was the adequacy of the vaccination schedule. The vaccination status was assessed for the diphtheria/tetanus, hepatitis B, hepatitis A, measles/mumps/rubella, yellow fever, 13- and 23-valent pneumococcal, meningococcal C, and HPV vaccines. Those who had received all of the recommended vaccinations in accordance with the schedule established by the government at the time of the assessment, without any delays, were classified as having received an "adequate schedule". The independent variables included sociodemographic, clinical-epidemiological, and social vulnerability factors, analyzed by multiple logistic regression with adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). Only 47 individuals (7.3%) had an adequate vaccination schedule for all vaccines. The vaccines with the highest adequacy rate were diphtheria and tetanus (533; 82.6%), and the one with the lowest rate was measles/mumps/rubella (MMR) (243; 37.7%). The main predictors of a complete vaccination schedule were the age group, place of clinical follow-up, and where they received their last doses of vaccines. Educational interventions for PLHIV and health professionals are needed to improve the vaccination coverage in this group.

Online course on vaccinating people with HIV/AIDS - effectiveness in the knowledge of nursing professionals

OBJECTIVE

analyzing the effectiveness of an educational intervention on the knowledge of nursing professionals regarding the immunization of people with the human immunodeficiency virus.

METHOD

a quasi-experimental study evaluated professionals' knowledge through a knowledge test applied before and after the development of an online training course. The data was analyzed using frequency, median, mean, standard deviation, and association tests.

RESULTS

the sample consisted of 77 nursing professionals whose mean age was 43.2 years (SD+/-8.2). More than half of the individuals worked in basic health units (58.4%), 22.1% worked in specialized services that provide clinical monitoring for people with the human immunodeficiency virus, and 42 (54.5%) were nursing assistants or technicians. The professionals' performance improved after the intervention, with an increase in the median number of correct answers from 23.0 to 27.0 (p<0.001).

CONCLUSION

offering an online training course on the immunization of people with the human immunodeficiency virus, as a continuing education activity, proved to be effective in improving nursing professionals' knowledge on this subject.

HIGHLIGHTS

(1) Services do not evaluate the vaccination status of people living with HIV.(2) The knowledge of health professionals may influence vaccination rates.(3) Health professionals' knowledge of immunization may be insufficient.

Vaccination Coverage of People Living with HIV: Before and after Interventional Action

This is a quasi-experimental study that assessed PLHIV vaccination coverage before and after health professionals participated in a training course on PLHIV immunization. The vaccination coverage of 645 PLHIV was assessed in the pre-intervention phase. The vaccine with the best coverage was diphtheria and tetanus (82.64%) and the one with the lowest rate of adequately vaccinated was measles, mumps, and rubella (38.27%). Individuals aged between 30 and 39 years had a 74.00% (1-0.26) lower chance of having the full vaccination schedule when compared to those aged between 10 and 19 years, and among those over 40 years, the chance was 87.00% (1-0.13) lower. Those who were vaccinated in Specialized Care Services (SCS) were 5.77 times more likely to be adequately vaccinated when compared to those who were vaccinated in other health services. Regarding the entire vaccination schedule evaluated, the number of adequately vaccinated increased from 47 (7.29%) to 76 (11.78%). Interventions targeting health professionals were effective in increasing vaccination coverage among PLHIV; however, the achieved coverage remained below the desired level. It is necessary to act on health professionals' knowledge and other aspects to effectively increase vaccination coverage.

Insufficient vaccine coverage and vaccine hesitancy in people living with HIV: A prospective study in outpatient clinics in the Paris region

Vaccine prevention strategies play a crucial role in the management of people living with HIV (PLWH). The aim of this study was to assess vaccination coverage and identify barriers to vaccine uptake in PLWH in the Paris region. A cross-sectional survey was conducted in PLWH in 16 hospitals in the Paris region. The vaccination status, characteristics, opinions, and behaviors of participants were collected using a face-to-face questionnaire and from medical records. A total of 338 PLWH were included (response rate 99.7 %). The median age of participants was 51 years (IQR: 41-58). Vaccination coverage was 77.3 % for hepatitis B (95 % CI: 72.3-81.8 %), 62.7 % for hepatitis A (57.3-67.9 %), 61.2 % for pneumococcal vaccines (55.8-66.5 %), 56.5 % for diphtheria/tetanus/poliomyelitis (DTP) (51.0-61.9 %), 44.7 % for seasonal influenza (39.3-50.1 %), 31.4 % for measles/mumps/rubella (26.4-36.6 %) and 38.5 % for meningococcal vaccine (13.9-68.4 %). The main reason for vaccine reluctance was related to the lack of vaccination proposals/reminders. The overall willingness to get vaccinated was 71.0 % (65.9-75.8 %). In the multivariable analysis, several factors were associated with a higher vaccine uptake; for DTP vaccine: higher education level, having vaccination records, being registered with a general practitioner; for seasonal influenza vaccine: age > 60 years, higher education level, being employed. The overall vaccination coverage was suboptimal. Development of strategies reducing missed opportunity to offer vaccines is needed.

Management care improvement of people living with HIV: definition of a targeted clinical pathway in a University Hospital of South Italy

BACKGROUND AND AIM

In the world 37,9 billions live with Human Immunodeficiency Virus and, despite the availability of retroviral therapy, they have an higher risk to acquire other infectious diseases and to develop severe complications. According to several guidelines their immunization is crucial but only some center have developed a specific scheduled pathway and vaccination coverage is very low.  Aim of this study is: a)incentivize the active and free of charge offer of vaccines and increase of immunization coverage; b) application and implementation of a shared clinical pathway avoiding reluctance, embarrassment or shame by patients for their condition; d) instauration of an empathic relationship between doctor and patient; e) evaluation of side effects.

METHODS

A prospective study was conducted from October 2019 to February 2020 at the University Hospital G. Martino of Messina. Inclusion criteria were: age over 18; absence of other diseases; absence of immunization against HBV or HAV; CD4 count for live attenuated viral vaccines of 350/uL and for other vaccine 200/uL. A specific scheduled pathway was adopted for every patient. Statistical analysis was performed with Excel software.

RESULTS

86 patients were enrolled (74.4% were males, 79.1% were Italian; mean age=4013.3 SD).  An increase in administration was observed between 2018 and 2019 (+164.3% for flu and for other vaccines +370%).  The higher increase was observed for HPV one. No-one received DTpa, MMRV or Zoster vaccine.

CONCLUSIONS

The undertook clinical pathway showed the relevance of specific management of these patients and the need to increase the vaccination offer.

Sociodemographic, HIV-Related Characteristics, and Health Care Factors as Predictors of Self-Reported Vaccination Coverage in a Nationwide Sample of People Aging with HIV in Germany

Preventing infectious diseases through vaccination becomes more significant among the growing population of people aging with HIV. Coverage rates for vaccinations and factors associated with vaccination utilization among this population in Germany are unknown. We assessed the coverage of eight recommended vaccinations in a certain time frame in our convenience sample of 903 people living with HIV aged 50 years and older. We analysed coverage rates and used bivariate and multiple linear regression analyses to identify factors associated with number of reported vaccinations. Coverage rates in our sample ranged between 51.0% for meningococcus disease and 84.6% for the triple vaccination against tetanus, diphtheria, and pertussis. All rates were higher compared to the German general population. Seven factors were related to the number of vaccinations in multiple regression analysis: sexual orientation, education, relationship status, CD4 count, time since last visit to HIV specialist, type of HIV specialist, and distance to HIV specialist. Vaccination coverage among people aging with HIV in Germany is high, but not optimal. To improve vaccination uptake, strengthened efforts need to be focused on female and heterosexual male patients, socioeconomically disadvantaged patients, and patients with barriers to access regular HIV care.
