Flu vaccination coverage in healthcare workers during a 3-year period in the context of the pandemic

Background

Vaccination of healthcare workers (HCWs) against seasonal influenza is considered the most effective way to protect HCWs and maintain essential healthcare services during influenza epidemics. With the present study we aimed to evaluate the efficacy of measures implemented during the three flu campaigns of 2018/19, 2019/20 and 2020/21 in a university hospital in Pisa, Italy, through the assessment of vaccination coverage (VC) in HCWs and to assess attitudes toward flu vaccination.

Methods

Flu VC was stratified according to sex, age, job and vaccination status for each season and the association between each variable and vaccination status was explored. In 2020, a survey collecting data on knowledge and attitudes on flu vaccination was distributed.

Results

Starting from the 2018/19 campaign, an increasing flu VC rate was registered: contained in 2019/20 (from 11.6% to 14.3%, Δ%=23.1) and significant (VC = 39.6%, Δ%=177.6) in 2020/21 as compared with the previous year. Physicians were the professionals most willing to get vaccinated during all seasons. Considering age the situation changed greatly over the study period, with VC rising in 2020/21 in those age groups marked by low VC in previous years (<30 and 41-50 years old, Δ%=293). Having been vaccinated in the previous year represented the most important variable to predict likelihood of accepting flu jab. However, while previously vaccinated HCWs were 13 times more likely to get the flu jab in 2019/20 compared with the others; in 2020/21 they were only 3 times. Only half of HCWS considered themselves at higher risk of contracting influenza compared to the general population, while 71% totally agreed that receiving the flu jab in 2020/21 was more important than the previous years due to COVID.

Conclusions

A significant increase in VC was observed in 2020/21, especially among those sub-groups with consistently lower uptake in previous years, due to the COVID pandemic that positively influenced vaccination uptake.

Key messages

• This study evaluates the impact of subsequent flu vaccination campaigns implemented in a large university hospital in Italy through the assessment of flu VC among HCWs.

• A significant increase in flu VC among HCWs was observed in 2020/21, especially in those categories characterized by lower VC rates in the previous years, more likely due to the COVID-19 pandemic.

Youth HIV services in the context of COVID-19 pandemic in Sofala Province, Mozambique

Background

After the first COVID-19 case in Mozambique, the government established a state of emergency in period April - September 2020. To reduce exposure for people living with HIV (PLWHIV), the Ministry of Health modified service delivery guidance, interrupting community activities, and revising patient flow within health facilities. The study aimed to measure the impact of the COVID-19 pandemic on HIV testing and treatment services in Sofala Province, Mozambique.

Methods

The study analysed the activities in 9 youth HIV services called SAAJs (Serviço amigo do adolescente e jovem) supported by Doctors with Africa CUAMM in 2020 and 2021. The following data were gathered and analysed: number of counselling sessions, number of HIV tests performed, number of people who tested positive and therefore started the antiretroviral treatment (ART), number of PLHIV on ART. Data were disaggregated by sex and age.

Results

In 2020 and 2021 85466 and 141844 counselling sessions were performed, respectively. A decrease of 41% was observed in the second trimester of 2020 compared with the previous one. The number of counselling sessions came back at pre-pandemic levels in the 2nd trimester of 2021. People aged 20-24 accessed more in 2020, while those aged 15-19 in 2021. In 2020 people tested for HIV were 22753, while the number was twice in 2021: the increase was higher among males(p<.05). In 2020 females were more likely to be tested, while in 2021 it was the opposite(p<.05). The positivity rate was 2.5% and 1.5%, respectively; in both years males were more likely to be tested positive(p<.05). In 2020 86.1% of people tested positive started the ART, in 2021 98%. Males were more at risk of not starting the ART(p<.05). The number of PLWHIV on ART did not decrease over time.

Conclusions

ART provision was generally maintained during the COVID-19 pandemic, while other services were heavily impacted. The difference observed among sex was significant and may inform future interventions.

“Laboratorium Repository”: a training tool for the Healthcare Workforce

Background

The COVID-19 pandemic highlighted the need to redefine the healthcare workforce (HCW) competencies to face future emergencies linked to emerging infectious diseases, environmental, climate and social crises. As recently stated by WHO, there is a need to identify standards for education and competencies training for HCW in emergency and preparedness (E&P). The Italian National Institute of Health, in agreement with the deliberation of the G20 Health Ministers under the Italian Presidency, is developing an educational program named “Laboratorium” which includes a free access digital repository aimed to share selected documents and tools at the International Public HCW (PHCW) to increase the competencies in E&P response.

Objectives

A range of web domains selected according to their reliability was monitored using a keyword search tool for any relevant material published from February 14th up to April 28th, 2022. We included any publications, training materials, epidemiological data, initiatives, and communication items that addressed the topic of interest. Each item was submitted for approval by a scientific board and, if appropriate, classified by typology, language, topic, and country before publication.

Results

To date, out of 6197 items, 418 fulfilled the inclusion criteria. For the type of content, we included guidelines/recommendations (75), epidemiological data (58), websites (34), online courses (15) and books (16). PHCW was the most representative target group (361), followed by other stakeholders (127), hospital practitioners (90), primary care (87). The most represented topic was infectious diseases/SARS-CoV-2 (277) followed by vaccines (88), emergency interventions (34), emerging diseases (17), policies (26), public health preparedness (32).

Conclusions

Future training for PHCW should be designed with a modular approach with different levels of usability. The Laboratorium Repository provides a core of items for learning according to one's training needs

Vaccine Hesitancy and Cognitive Biases: A tailored approach for a better communication

Background

Vaccine hesitancy (VH) remains worldwide a reason of concern. Most of the vaccination education strategies followed a ‘fact-based' approach, based on the assumption that decision making is a rational process, without considering the influence of cognitive biases and heuristics. Our study aimed at identifying factors involved in the parents' vaccination choice to inform and shape communication interventions.

Methods

We conducted an online national survey among parents between November 2020 and April 2021. The questionnaire consisted of 59 items organised in 5 parts: personal information, cognitive biases, risk aversion, conspiracy mentality, and VH. Exploratory factor analysis was conducted to identify latent variables underlying the 19 items related to the 6 cognitive biases. Factors were categorised in quintiles and the corresponding pseudo-continuous variables used as predictors of the VH. Logistic regression model was applied to assess the association of the VH with factors, conspiracy mentality and risk propension. We adjusted for age, gender, economic status, and education levels.

Results

The study included 939 parents, 764 women (81.4%), 69.8% had a degree or higher level of education. Considering cognitive biases, four factors explaining 54% of the total variance were identified and characterised as: fear of the side effects of vaccines (scepticism factor); carelessness of the risk and consequences of infections (denial factor); optimistic attitude (optimistic bias factor); preference for natural products (naturalness bias factor). All factors were positively associated with VH (p &lt; 0.001) as were conspiracy mentality (p = 0.007) and risk propension (p = 0.002).

Conclusions

This study confirmed the need to amplify the model used to analyse the VH considering cognitive biases as an important factor affecting the parents' decision making. These results may be useful to design personalised communication interventions regarding vaccines and vaccination.

Key messages

The model used to analyse the vaccine hesitancy needs to be extended including the evaluation of cognitive biases and heuristics. Communication interventions to promote vaccine acceptance should be tailored and personalized on the basis of the drivers of choice of the parents.

Risk of Sars-CoV-2 infection and disease severity in people at socioeconomic disadvantage in Italy

Background

Evidence accumulated in the past months indicating that COVID-19 affects people at socioeconomic (SE) disadvantage more strongly. This is embodied by the COVID-19 syndemic concept, i.e., the biological, economic, and social interactions between non-communicable diseases and COVID-19 increase a person's susceptibility to infection and worse health outcomes. Here, we explored the relationship among the SE position and the risk of Sars-CoV-2 infection and disease severity in Tuscany and Apulia, two Italian regions, during the 1st(Feb-Jun2020) and 2nd(Sep-Dec2020) epidemic waves.

Methods

We included all individuals tested (only for Apulia) and/or resulted positive for SARS-CoV2(for Tuscany and Apulia) and reported to regional surveillance system. We linked surveillance data with the deprivation index (DI)(1-5 scale; DI = 5 highest deprivation) of the area of living. We calculated the relative risk (RR) of acquiring Sars-CoV-2, COVID-19-related hospitalization, and death of deprived individuals compared with people in the highest SEP-we adjusted for gender and age.

Results

A total of 159507 (82897 F; 76610 M) individuals with prior or current Sars-CoV-2 infection were included in our study, 71320 from Apulia and 88187 from Tuscany. For people aged over 30, and with a DI &gt; 2, the RR of acquiring the infection increased for individuals with higher DI. The RR of being hospitalized and of death, were significantly higher for people over 30 with DI = 5. In Apulia, test positivity rate was comparable across all population groups during the 1stwave, while it increased among individuals with higher DI during the 2ndwave.

Conclusions

According to our results, SE disadvantage is associated with an increased risk of acquiring Sars-CoV-2, and to suffer from severe outcomes when infected. Based on available data, diagnostic test access was more equitable during 1stepidemic wave. This study calls for targeted health policies and actions to protect those with the greatest SE vulnerability.

Key messages

Available Italian data, indicate that higher socioeconomic disadvantage is associated with an increased risk of acquiring Sars-CoV-2, and to suffer from severe outcomes when infected. Our study highlights the importance of adopting targeted health policies and action to protect those with the greatest socioeconomic vulnerability and enhance equity.

Vaccine hesitancy and Health Literacy: we need to change our paradigm

Introduction

The vaccination coverage decline and the re-emergence of vaccine preventable diseases draw attention to the problem of vaccine hesitancy (VH). Many studies demonstrated that the current vaccine education is not very effective. We analysed the problem of VH in relation to Health Literacy (HL) and the perception of vaccine preventable diseases-related risks in a sample of parents.

Methods

We conducted a survey among parents between February and November 2018. We collected data on demographic, main sources of information, vaccination attitude (using the Vaccine Confidence Index (VCI) adapted from Larson HJ 2016), HL levels(using an adapted version of IMETER and knowledge of signs and symptoms of diphtheria, tetanus and measles.

Results

The study included 772 parents, 620 women (mean age 39 years), 48.2% had diploma. The main source of information was the doctor (85.5%) followed by the web(24.2%). The average VCI was 3.78(range: 0.1-10) with lower values among parents informed through social networks (2.05-2.78). Analysing the IMETER test, 90% had a good or acceptable level of HL. No significant correlation between VCI and HL was found. For parents who identified at least 3 specific elements of selected diseases, the average VCI was significantly higher(Measles 4.32,Tetanus 4.64,Diphtheria 5.84).

Conclusions

The HL level did not correlate with the VCI. A low VCI was associated with poor knowledge of selected diseases: this confirms the importance of a correct risk perception. This study in accordance with the literature suggests to amplify the model used to analyse the VH taking into account cognitive biases (i.e. ambiguity aversion and omission bias) as important factor affecting the parents' decision making. We aim to expand our work building a survey to categorise parents according their main cognitive bias. This may be useful to understand the better communication strategies to effectively have an impact on each parents' behaviour.

Key messages

This study in accordance with the literature suggests to amplify the model used to analyse the VH taking into account cognitive biases. The Health Literacy is not enough to explain the problem of the Vaccine Hesitancy.

“Transfer, Contestation and Conflict”: How Italian regional and national governments claim and challenge authority in mandatory vaccination policies

Background

This paper explores conflictual policy transfer in Italian vaccination policy 2007-2018. The region of Veneto formally suspended mandatory vaccination in 2007. Soon after, declining vaccination rates across the country sparked a public health crisis. Emilia Romagna adopted a new vaccine mandate for early education, which the national government adopted in 2017. Each policy decision invoked collaboration and contestation between governments. In showing the conflictual aspects of intra-state policy transfer, we offer lessons for multi-level health governance of contested issues.

Methods

We used qualitative documentary analysis of parliamentary transcripts, legislation and government reports, supplemented with semi-structured key informant interviews, using the coding software NVivo 12. We applied theoretical and conceptual scholarship to develop an analytical framework drawing out the key mechanisms through which contestation and conflict take place.

Results

Italian regional and national governments employed three key mechanisms to forcibly transfer or resist vaccination policy: ideas, evidence, and law. Ideas included “the nation”, “herd immunity” and “science.” Evidence included coverage rates and explanations of changes over time. Protagonists of Italy's coercive policy transfers used the law to claim and challenge authority. Contestations occurred in political and bureaucratic spheres. Discrepant historical and evidentiary narratives emerged between levels of government that had injected significant resources into acquiring or defending governance of vaccination policy.

Conclusions

Scholarship has predominantly considered coercive policy transfer at a supra-national or inter-state level. We demonstrate the political blood-spilling within a country when divergent regional policies become contested in a situation of national crisis. 'Evidence' and 'law' can be open to differing interpretations, with 'ideas' shaping the context in which policies prevail.

Communication breakdown in Italy’s vaccination governance

Background

In 2017, Italy rebooted its mandatory vaccination regime, following a series of unfavourable court decisions placing vaccination in disrepute. Vaccination rates had steadily declined for half a decade, culminating in a measles epidemic. Existing studies demonstrate the role of vaccine hesitancy, but none have explored the role of government in the years prior to the new mandate. This study analyses the drivers of failures to address sliding vaccine confidence in Italy.

Methods

We engaged in qualitative analysis of primary sources, Italian and international scholarship, and semi-structured interviews with key informants. These were analysed using the coding software NVivo 12. We developed an empirically and theoretically informed schema to make sense of governance failures in knowledge and action.

Results

The resort to mandates in 2017 was triggered by a series of unfortunate events, further thwarted by governance capacity gaps. During 2012-2017, Italy's vaccination governance included no online campaigns to address concerns. Public health officials lacked crucial knowledge regarding the population, including strategies to address hesitancy. They were preoccupied with other significant changes to Italy's vaccination governance, notably the vaccination schedule. Limited financial resources from the political class constrained officials' capacity in a context of austerity. A credibility gap ensued, which officials sought to plug by constructing Italians as in need of firm instruction by mandatory vaccination.

Conclusions

When voluntary vaccination failed in Italy, the new mandates improved coverage rates. However, the vaccine confidence work explored in this study should not be neglected. The future governance of vaccine confidence requires that effective communications to address vaccine confidence be implemented Italy and other jurisdictions facing vaccine hesitancy and refusal problems.

Key messages

We analyse the Italian government’s response to the crisis of vaccine confidence prior to the introduction of mandates, in order to provide lessons for other governments. We identify and explain the gaps in governance capacity that prevented the addressing of sliding coverage rates.

Migration and infectious disease risk: knowledge and perception among European students

Background

In the past years migration has increasingly affected the European continent. The concerns of the local population about infection spread by migrants may increase unjustified stigma. Literature has shown that stigma is a determinant of health. The aim of our study was to assess the knowledge and risk perception of infectious disease introduced by migration.

Methods

Between January and February 2020 we conducted an online survey in Italian and Spanish University students. We collected data on demographics, perception and knowledge of transmission of infectious diseases introduced by migration. We performed a descriptive and a risk factors analysis to assess correlation between our variables.

Results

We collected 1397 answers: 1022(73.16%) from Italian students (F:668/1022, M:341/1022, others:13/1022) and 375(26.84%) from Spanish students(F:253/375,M:119/375, others:3/375) The median age was 24 for Italy and 22 for Spain. In Italy and Spain, respectively, 353/1022(34,54%), 145/375(38,67%) students were from the healthcare area, 316/1022(30,92%), 74/375(19,73%) the scientific area, 349/1022(34,15%), 108/375(28,80%) the non-scientific area and 4/1022(0,39%), 48/375(12,80%) from others area. We found a statistically significant correlation between the knowledge of infectious diseases and the perception of the infectious risk associated with migration. This correlation was not confirmed for the area of study. Healthcare students had the best levels of knowledge and perception of the migratory phenomenon, but the higher perception of infectious risk.

Exposure to the news was associated with the worst perception of the migratory phenomenon and the infectious risk (p &lt; 0.001).

Conclusions

Our study showed that students in the health area had the highest risk perception of infectious diseases. Therefore, the introduction of the course on migration medicine and the increase of practical training could help to reduce the altered risk perception of infectious diseases.

Key messages

The introduction of the course on migration medicine and the increase of practical training could help to reduce the altered risk perception of infectious diseases in healthcare students. Exposure to the news has a negative effect on the perception of the migratory phenomenon and the ìnfectious disease.

Feasibility of HCV micro-elimination: HCV test and treatment in two harm reduction services in Milan

Background

Most of Harm Reduction Service (HRS) users represent a crucial high-risk population for blood borne infections, including HCV. With the advent of new direct antiviral agents (DAAs), HCV micro-elimination in this setting has become feasible. We evaluated HCV treatment cascade in two HRSs located in Milan.

Methods

We collected data on demographics, substance abuse history, HIV prevalence, HCV prevalence, testing and treatment on all register HRS users on 1 January 2019. Data collection was closed on 1 January 2020.

Results

A total of 881 HRS users (732M,149F) were included (median age: 45). The majority was addicted to heroin 67.5% (595), 24.1%(212) to cocaine, 5.3%(47) to THC and 3.1%(27) to other substances. The 28.0%(247/881) reported current or prior judiciary problems, 168/881(19.1%) were under psychiatric treatment. HCV serological screening (HCVAb) was performed for 587/881(66.7%), 113/881(12.8%) were in process, 2/881(0.2%) refused, 179/881(20.3%) were not HRS user anymore. 364/587(62%) resulted HCVAb positive, of whom 288(79.1%) were tested for HCV RNA. Among them 123/324(37.9%) were positive, 165/324(50.9%) were negative. Among HCVAb positive, 116/364(31.9%) were tested for HIV and 92(79.3%) resulted HIV positive. Among HCV RNA positive 92/123(74.8%) were initiated on DAAs treatment. Compliance to treatment was high; one treatment failure was registered. Individuals tested for HCV and HCVAb positive people had an average age significantly higher than the individuals not tested and HCVAb negative people (p &lt; 0.001). Heroin user had a higher likelihood of being tested both for HCVAb and for HCV RNA and of being positive to the HCVAb test (p &lt; 0.001).

Conclusions

Our study demonstrate that it is feasible to achieve good efficacy and compliance for HCV treatment among people who use drugs when decentralising treatment to HRS. To achieve the viral hepatitis elimination agenda goals, HRS-based model of treatment provision needs to be implemented at larger scale.

Key messages

Decentralising HCV test and treatment to harm reduction services is an effective strategy to achieve HCV micro-elimination among people who use drugs. Young people and people who are addicted to other substance than heroin resulted more difficult to link to HCV care through the harm reduction services. They require tailored intervention.

Systematic review on Screening for antimicrobial-resistant Gram-negative bacteria in inpatients

Background

Infections with antimicrobial-resistant Gram-negative bacteria (AMR-GNB) are increasingly being reported worldwide. Early identification of carriage at hospital admission is essential to reduce the risk of onward transmission within the health facility. This systematic review aimed at exploring screening practices for AMR-GNB faecal colonization among patients on admission to hospital in high-income countries and estimating its prevalence.

Methods

We searched on Pubmed, Scopus and Cochrane databases for studies published from 2010 up to April 2019. We included studies reporting on patients ≥18 years old and hospitalised (excluding long-term care facilities).

Results

The search retrieved 9496 articles, 85 were included after screening: 10 reported screening activities in outbreak situations (not included in the analysis); 75 in non-outbreak situations. Based on the target patient groups and setting we identified four subsets of screening approaches: all admitted (AA) in high risk (HR) wards (36 studies, 48%), HR patients in HR wards (12, 16%), HR patients in low risk wards (LRW) (11; 15%) and AA - LRW (15, 20%). HR patients-based screening targeted patients with certain clinical conditions (mostly oncologic patients, 37%), travellers 29%, previously hospitalised and individuals with multiple risks 34%. HR wards-based screening was performed mostly in ICU (73%), while LRW-based screening in hospital-wide setting (58%). We investigated the overall prevalence rates of AMR-GNB (15.1%; 95%CI: 9.5-21.6), Klebsiella spp (KB) (4.1%; 3.1-5.3), E. coli (9.6%; 7.7-11.7) P. Aeruginosa (7.6%; 1.7-16.8), A. Baumannii (2.1%; 0.5-4.4) and other Enterobacterales (0.8%; 0.59-1.1). Reported KB-prevalence varied according to screening approaches, with statistically significant higher prevalence in HR wards.

Conclusions

According to our data, screening for AMR-GNB mostly followed targeted approaches. Overall prevalence of AMR-GNB carriage at hospital admission was considerable.

Key messages

This systematic review gives un overview on the screening procedures for AMR-GNB faecal colonization among patients on hospital admission in high-income countries. According to our results, overall prevalence of AMR-GNB carriage was considerable (15.1%), varying among specific pathogens but with no significant correlation with screening approaches, except for KB.

Legitimising a ‘Zombie idea’: childhood vaccines and autism

Background

In June 2017 the Italian government made childhood vaccination mandatory following a drop in immunization rates. In the years preceding, two court judgments affirmed a causal link between vaccines and autism. Studies have linked these decisions to internet searches about vaccine-autism, the popularity of 'no-vax' theories, and drops in immunization rates. This paper provides an in-depth case study of both decisions and their impact.

Methods

We use a synthetic research design reliant on: (i) a systematic collection of primary sources (publicly available and obtained via official access to information requests); (ii) interviews with key actors prominently involved in the two cases or privy to the Italian vaccine-injury compensation regime (iii) a systematic analysis of media coverage.

Results

Circumstantial and systemic flaws enabled these decisions. Poor trial strategies, insufficient resources and laborious communication practices between arms of government were facilitators. Lack of awareness of the social sensitivity of vaccine issues, underestimation of the phenomenon of vaccine hesitancy, and a tendency to 'think in silos' informed the lack of attention dedicated to the cases. The decisions created false expectations of economic benefits and vindication for families with autistic children, resulting in increased litigation. Systemic flaws exist in the process of appointment of expert consultants acting for the court leading to judicial reliance on false data.

Conclusions

Lessons learned include greater levels of attention to vaccine cases by the administration and a matured attitude of adjudicating bodies. Two issues remain: (i) the inability of government lawyers to disseminate positive results to counteract unfounded narratives; (ii) flaws in the process of appointing expert consultants advising courts, which remains focused on the fiduciary nature of the relationship, rather than scientific authority.

Key messages

The Milan and Rimini decisions that directly affected vaccine governance stemmed from a combination of circumstantial decision-making and systemic flaws that still lurk in public health governance. Strategic decision-making that overlooks lower levels of the adjudicative system can lead to significant public health consequences as courts of law and courts of public opinion obey different logics.

Risk of infection in antimicrobial-resistant Gram-negative bacteria carriers: A systematic review

Background

Antimicrobial-resistant Gram-negative bacteria (AMR-GNB) have emerged as important health care-associated pathogens. Infections with AMR-GNB are associated with high patient morbidity and attributable mortality. Colonization is a prerequisite for infection, however the extent to which colonized patients develop infection is unclear. This systematic review explored the risk of developing infection during hospitalisation among AMR-GNB faecal carriers. Also, we investigated the acquisition rate for AMR-GNB colonization among patients not colonized at admission.

Methods

We searched on PubMed, Scopus and Cochrane databases for studies published from 2010 up to April 2019. We included studies reporting on hospitalised patients ≥18 years old in high-income countries (excluding long-term care facilities).

Results

Out of 9496 articles, 55 studies fulfilled our inclusion criteria. Forty-two studies reported data from EU/EEA, 6 from USA and 7 from other regions. Almost all studies (n = 45) were conducted in university hospitals. Most studies (n = 41;74.5%) were performed in high-risk wards (ICU, haematology, burn units and transplant units). Out of 55 studies, 8 examined AMR-GNB, 27 Enterobacteriaceae, while the others investigated specific pathogens: Klebsiella spp. (n = 11), E. Coli (n = 2), A. Baumannii (n = 3) and P. Aeruginosa (n = 4). The rate of AMR-GNB carriage acquisition was 10.5% (n = 40 studies; 95% CI:8.2-13.1). The risk of progression to infection among patients colonized at hospital admission was 13.9% (n = 15; 5.4-24.9), while the infection rate in patients who acquired carriage during hospitalization was 23.0% (n = 7; 5.9-45.2). Patients with an undefined time of colonization presented an infection rate of 16.9% (n = 13; 11.2-23.4). Considering these three populations as a whole, the risk of developing infection was 16.0% (11.0-21.0).

Conclusions

Our results suggest that risk of progression to infection in AMR-GNB colonized patients in hospital setting is high.

Key messages

The aim of our study was to estimate the risk of progression to infection, during hospital stay, in patients colonized by AMR-GNB at hospital admission in high-income countries. Our results suggest that faecal colonization with AMR-GNB poses a 16.0% risk of subsequent AMR-GNB infection. This risk in higher (23.0%) in patients who acquired colonization during hospitalisation.

HCV test&treat in Milan prisons-an effective strategy for microelimination and health gaps reduction

Background

People in prison represent a high-risk population for HCV infection control due the overrepresentation of people with a history of intravenous drug use, psychiatric patients and other vulnerable populations who have often reduced access to healthcare. With the advent of new direct antiviral agents (DAAs) HCV micro-elimination in prison setting became a feasible strategy.

Methods

We conducted in 2017 and 2018 a cross-sectional evaluation of HCV treatment cascade in one detention prison, Opera (OP), and one pre-trial detention center, San Vittore (SV) in Milan. A dedicated protocol for HCV eligibility and care was applied. We collected data on demographics, HCV testing and treatment on all inmates on October 31st 2017 and 2018. Data collection ended on December 31st of each year.

Results

On October 31st 2017, 2366 inmates were living in the two facilities, 2369 in 2018, of these, 1036 (43,7%) were already present in 2017 (71,3% in OP; 28,7% in SV). In both years the majority were men (95.4%; 96,4%) with a median age of 41 years and Italians (57%; 61,9%). Prevalence of reported drug use remained high (46,5%; 44,2%). HCV screening coverage was 89% in both years, while HCV-RNA test coverage increased (90,6%; 99%). HCV Ab+ was stable (212, 10.1%; 194, 9,2%). At the end of 2017 and 2018, 106 (50%) and 117 (60,3%) started treatment eligibility process of which 90 (42,4%) and 106 (54,6%) completed DAAs in prison. Considering last available viremia, 41 inmates (19,3%) were viremic in 2017 (OP 16.1%; SV 24,4%), while only 13 inmates (6,7%) in 2018 (OP &lt; 1%, SV 15,4%). On December 31st 2018, among HCV Ab+ detainees 122 (62,9%) were never linked to care before incarceration.

Conclusions

Our study shows the success of the HCV testing and treatment strategy to achieve HCV micro-elimination in a prison setting with a significant drop in the pool of viremic individuals. We highlight how prison health care may represent a unique point of access for vulnerable population.

Key messages

HCV micro-elimination is a feasible and effective strategy in prison settings. High-quality healthcare in prison contributes to reduce health gaps and improve access for socially deprived population.
