RESUMEN

OBJECTIVE: To evaluate the impact of hepatitis C virus (HCV) infection and treatment status on COVID-19-related hospitalizations in Georgia. METHODS: We analyzed 2020-2021 Georgian health-registry data for COVID-19-positive individuals and categorized by HCV infection and treatment status. Logistic regression was used to assess the strengths of the associations. RESULTS: Treated HCV individuals had lower odds of COVID-19-related hospitalization compared to anti-HCV-negatives, while untreated HCV-viremic and anti-HCV-positive non-viremic individuals had higher odds. CONCLUSIONS: HCV treatment prior to COVID-19 infection was associated with lower odds of COVID-19-related hospitalization, highlighting the benefits of HCV management in the context of the pandemic.

RESUMEN

BACKGROUND: Rapid antigen-detection tests for SARS-CoV-2 self-testing represent a useful tool for pandemic control and expanding access to community-level case screening. COVID-19 self-tests have been extensively used in high-income countries since 2021; however, their introduction and programmatic implementation in low- and middle-income countries was delayed. We aimed to identify and continuously improve a weekly COVID-19 self-testing model among staff at healthcare facilities and schools. METHODS: This mixed-methods, observational prospective study was conducted in 5 healthcare centres and 24 schools in Georgia, between June and December 2022. The study comprised the integration of COVID-19 self-testing into the national mandatory testing programme for high-risk groups, with primary distribution of self-tests among staff performed weekly, plus secondary distribution to their household members. These use cases were selected because NCDC was seeking to strengthen their already strong weekly testing programme, by investigating self-testing to ease the burden of testing in the healthcare system. Online surveys and semi-structured interviews were used for data collection. RESULTS: In total, 2156 participants were enrolled (1963 female, 72%). At baseline and mid- and end-points, 88%, 97% and 99%, respectively, of participants agreed/strongly agreed they would self-test. Similarly, the majority were willing to report their self-testing results (88%, 98% and 96% at baseline and mid- and end-points, respectively). Weekly reporting of test results to the national COVID-19 database was high during all the implementation. There were 622 COVID-19 positive results reported, and linked to care, from 601 individuals (282 participants and 319 household members). Findings from qualitative interviews showed great satisfaction with self-testing for its convenience, ease of use, trust in the results, no need to travel for diagnostics, and increased perception of safety. CONCLUSIONS: Our findings contribute to the evidence-base regarding self-testing strategies conducted via workplaces and secondary distribution to households. Willingness to perform a COVID-19 self-test increased after implementation. This pilot enhanced pandemic preparedness through expansion of the national self-testing reporting system, development of communications materials, changes in the national legal framework and coordination mechanisms, and improved perceptions around self-care in the community. The lessons learnt can inform operational aspects of the introduction and scale-up of self-care strategies.

RESUMEN

BACKGROUND: Georgia experienced an increase in maternal deaths (MD) during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which warrants further investigation. This study aimed to assess associations between timing of SARS-CoV-2 infection during pregnancy and MD, post-delivery intensive care unit (ICU) admission, and caesarean section (CS) delivery. METHODS: We performed a national birth registry-based cohort study of pregnant women who had completed 22 weeks of gestation and delivered between February 28, 2020, and August 31, 2022. The data were linked to coronavirus disease 2019 (COVID-19) testing, vital, and immunization registries. Pregnant women were classified into three groups: confirmed SARS-CoV-2 infection from conception through 31 days before delivery; confirmed infection within 30 days before or at delivery; and women negative for SARS-CoV-2 infection or without any test results (reference group). Multivariable logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Among 111,493 pregnant women, 16,751 had confirmed infection during pregnancy, and 7,332 were fully vaccinated against COVID-19 before delivery. Compared to the reference group, those with confirmed infection within 30 days before or at delivery experienced increased odds of MD (aOR: 43.11, 95% CI, 21.99-84.55), post-delivery ICU admission (aOR: 5.20, 95% CI, 4.05-6.67), and CS delivery (aOR: 1.11, 95% CI, 1.03-1.20). CONCLUSIONS: Pregnant women in Georgia with confirmed SARS-CoV-2 infection within 30 days before or at delivery experienced a considerably higher risk of MD and post-delivery ICU admission and a slightly higher risk for CS delivery. Additionally, the results highlighted that most pregnant women were not vaccinated against COVID-19. These findings should alert stakeholders that adherence to public health preventive measures needs to be improved.

RESUMEN

In the Republic of Georgia, a 2018 national survey estimated that more than 40% of children aged 2-7 years had a blood lead concentration (BLC) of more than 5 µg/dL. The objective of this study was to document the feasibility of employing lead isotope ratios (LIRs) to identify and rank the Pb (lead) exposure sources most relevant to children across Georgia. A cross-sectional survey between November 2019 and February 2020 of 36 children previously identified as having BLCs > 5 µg/dL from seven regions of Georgia involved the collection of blood and 528 environmental samples, a questionnaire on behaviours and potential exposures. The LIRs in blood and environmental samples were analysed in individual children and across the whole group to ascertain clustering. A fitted statistical mixed-effect model to LIR data first found that the blood samples clustered with spices, tea, and paint, then, further isotopically distinct from blood were sand, dust, and soil, and lastly, milk, toys, pens, flour, and water. Analysis of the LIRs provided an indication and ranking of the importance of Pb environmental sources as explanatory factors of BLCs across the group of children. The findings support the deployment of interventions aimed at managing the priority sources of exposure in this population.

RESUMEN

BackgroundGeorgia has adopted the World Health Organization European Region's and global goals to eliminate viral hepatitis. A nationwide serosurvey among adults in 2015 showed 2.9% prevalence for hepatitis B virus (HBV) surface antigen (HBsAg) and 25.9% for antibodies against HBV core antigen (anti-HBc). HBV infection prevalence among children had previously not been assessed.AimWe aimed to assess HBV infection prevalence among children and update estimates for adults in Georgia.MethodsThis nationwide cross-sectional serosurvey conducted in 2021 among persons aged ≥ 5 years used multi-stage stratified cluster design. Participants aged 5-20 years were eligible for hepatitis B vaccination as infants. Blood samples were tested for anti-HBc and, if positive, for HBsAg. Weighted proportions and 95% confidence intervals (CI) were calculated for both markers.ResultsAmong 5-17 year-olds (n = 1,473), 0.03% (95% CI: 0-0.19) were HBsAg-positive and 0.7% (95% CI: 0.3-1.6) were anti-HBc-positive. Among adults (n = 7,237), 2.7% (95% CI: 2.3-3.4) were HBsAg-positive and 21.7% (95% CI: 20.4-23.2) anti-HBc-positive; HBsAg prevalence was lowest (0.2%; 95% CI: 0.0-1.5) among 18-23-year-olds and highest (8.6%; 95% CI: 6.1-12.1) among 35-39-year-olds.ConclusionsHepatitis B vaccination in Georgia had remarkable impact. In 2021, HBsAg prevalence among children was well below the 0.5% hepatitis B control target of the European Region and met the ≤ 0.1% HBsAg seroprevalence target for elimination of mother-to-child transmission of HBV. Chronic HBV infection remains a problem among adults born before vaccine introduction. Screening, treatment and preventive interventions among adults, and sustained high immunisation coverage among children, can help eliminate hepatitis B in Georgia by 2030.

RESUMEN

BackgroundBetween May 2015 and February 2022, 77,168 hepatitis C virus (HCV)-infected people in Georgia have been treated through an HCV elimination programme. To project the programme's long-term impacts, an HCV infection model was initially developed, based on data from surveys among people who inject drugs and a national serosurvey in 2015.AimAccounting for follow-up surveys in 2021, we validate and update projections of HCV infection prevalence and incidence.MethodWe assessed the initial model projections' accuracy for overall prevalence, by age, sex, and among people who ever injected drugs, compared with 2021 serosurvey data. We used 2021 results to weight model fits and to recalculate the national programme's impact leading up to March 2022 on HCV infection incidence rates. Cases and deaths averted were estimated. The impact of reduced treatment rates during the COVID-19 pandemic was assessed.ResultsThe original model overpredicted adult (≥ 18 years old) chronic HCV infection prevalence for 2021 (2.7%; 95% credible interval (CrI): 1.9-3.5%) compared with a 2021 serosurvey (1.8%; 95% confidence interval (CI): 1.3-2.4%). Weighted model projections estimated a 60% decrease in HCV infection incidence by March 2022, with an absolute incidence of 66 (95% CrI: 34-131) per 100,000 person-years (overall population). Between May 2015 and March 2022, 9,186 (95% CrI: 5,396-16,720) infections and 842 (95% CrI: 489-1,324) deaths were averted. The COVID-19 pandemic resulted in 13,344 (95% CrI: 13,236-13,437) fewer treatments and 438 (95% CrI: 223-744) fewer averted infections by March 2022.ConclusionResults support the programme's high effectiveness. At current treatment rate (406/month), 90% reductions in prevalence and incidence in Georgia are achievable by 2030.

RESUMEN

BACKGROUND: Mortality related to hepatitis C virus (HCV) infection is a key indicator for elimination. We assessed the impact of HCV infection and treatment on mortality in the country of Georgia during 2015-2020. METHODS: We conducted a population-based cohort study using data from Georgia's national HCV Elimination Program and death registry. We calculated all-cause mortality rates in 6 cohorts: (1) Negative for anti-HCV; (2) anti-HCV positive, unknown viremia status; (3) current HCV infection and untreated; (4) discontinued treatment; (5) completed treatment, no sustained virologic response (SVR) assessment; (6) completed treatment and achieved SVR. Cox proportional hazards models were used to calculate adjusted hazards ratios and confidence intervals. We calculated the cause-specific mortality rates attributable to liver-related causes. RESULTS: After a median follow-up of 743 days, 100 371 (5.7%) of 1 764 324 study participants died. The highest mortality rate was observed among HCV infected patients who discontinued treatment (10.62 deaths per 100 PY, 95% confidence interval [CI]: 9.65, 11.68), and untreated group (10.33 deaths per 100 PY, 95% CI: 9.96, 10.71). In adjusted Cox proportional hazards model, the untreated group had almost 6-times higher hazard of death compared to treated groups with or without documented SVR (adjusted hazard ratio [aHR] = 5.56, 95% CI: 4.89, 6.31). Those who achieved SVR had consistently lower liver-related mortality compared to cohorts with current or past exposure to HCV. CONCLUSIONS: This large population-based cohort study demonstrated the marked beneficial association between hepatitis C treatment and mortality. The high mortality rates observed among HCV infected and untreated persons highlights the need to prioritize linkage to care and treatment to achieve elimination goals.

RESUMEN

BACKGROUND: The country of Georgia initiated its hepatitis C virus (HCV) elimination program in 2015, at which point a serosurvey showed the adult prevalence of HCV antibody (anti-HCV) and HCV RNA to be 7.7% and 5.4%, respectively. This analysis reports hepatitis C results of a follow-up serosurvey conducted in 2021, and progress towards elimination. METHODS: The serosurvey used a stratified, multistage cluster design with systematic sampling to include adults and children (aged 5-17 years) providing consent (or assent with parental consent). Blood samples were tested for anti-HCV and if positive, HCV RNA. Weighted proportions and 95% confidence intervals (CI) were compared with 2015 age-adjusted estimates. RESULTS: Overall, 7237 adults and 1473 children were surveyed. Among adults, the prevalence of anti-HCV was 6.8% (95% CI, 5.9-7.7). The HCV RNA prevalence was 1.8% (95% CI, 1.3-2.4), representing a 67% reduction since 2015. HCV RNA prevalence decreased among those reporting risk factors of ever injecting drugs (51.1% to 17.8%), and ever receiving a blood transfusion (13.1% to 3.8%; both P < .001). No children tested positive for anti-HCV or HCV RNA. CONCLUSIONS: These results demonstrate substantial progress made in Georgia since 2015. These findings can inform strategies to meet HCV elimination targets.

RESUMEN

BACKGROUND: In 2015, the country of Georgia initiated its hepatitis C virus (HCV) elimination program. Given a high background incidence of HCV infection, centralized nucleic acid testing (NAT) of blood donations was prioritized for implementation. STUDY DESIGN AND METHODS: Multiplex NAT screening for HIV, HCV and hepatitis B virus (HBV) was launched in January 2020. An analysis was conducted of serological and NAT donor/donation data for the first year of screening (through December 2020). RESULTS: A total of 54,116 donations representing 39,164 unique donors were evaluated. Overall, 671 donors (1.7%) tested positive for at least one infectious marker by serology or NAT, with the highest prevalence among donors aged 40-49 years (2.5%; n = 200), male (1.9%; n = 524), replacement (2.8%; n = 153) and first time (2.1%; n = 642) donors. Sixty donations were seronegative but NAT positive, and therefore would not have been found by traditional serology testing alone. These were more likely among female vs. male (adjusted odds ratio [aOR] 2.06; 95% confidence interval [95%CI]: 1.05-4.05), paid (aOR 10.15; 95%CI: 2.80-36.86) or voluntary (aOR 4.30; 95%CI: 1.27-14.56) vs replacement, and repeat vs. first time (aOR 13.98; 95%CI: 4.06-48.12) donors. On repeat serological testing (including HBV core antibody [HBcAb] testing), 6 HBV + donations, 5 HCV + donations and 1 HIV + donations were deemed NAT yield (detected through the implementation of NAT, and would have otherwise been missed by serology screening alone). CONCLUSION: This analysis offers a regional model for NAT implementation, demonstrating the feasibility and clinical utility in a nationwide blood program.

RESUMEN

BACKGROUND AND AIMS: In 2015, the country of Georgia launched an elimination program aiming to reduce the prevalence of Hepatitis C virus (HCV) infection by 90% from 5.4% prevalence (~150 000 people). During the first 2.5 years of the program, 770 832 people were screened, 48 575 were diagnosed with active HCV infection, and 41 483 patients were treated with direct-acting antiviral (DAA)-based regimens, with a >95% cure rate. METHODS: We modelled the incremental cost-effectiveness ratio (ICER) of HCV screening, diagnosis and treatment between April 2015 and November 2017 compared to no treatment, in terms of cost per quality-adjusted life year (QALY) gained in 2017 US dollars, with a 3% discount rate over 25 years. We compared the ICER to willingness-to-pay (WTP) thresholds of US$4357 (GDP) and US$871 (opportunity cost) per QALY gained. RESULTS: The average cost of screening, HCV viremia testing, and treatment per patient treated was $386 to the provider, $225 to the patient and $1042 for generic DAAs. At 3% discount, 0.57 QALYs were gained per patient treated. The ICER from the perspective of the provider including generic DAAs was $2285 per QALY gained, which is cost-effective at the $4357 WTP threshold, while if patient costs are included, it is just above the threshold at $4398/QALY. All other scenarios examined in sensitivity analyses remain cost-effective except for assuming a shorter time horizon to the end of 2025 or including the list price DAA cost. Reducing or excluding DAA costs reduced the ICER below the opportunity-cost WTP threshold. CONCLUSIONS: The Georgian HCV elimination program provides valuable evidence that national programs for scaling up HCV screening and treatment for achieving HCV elimination can be cost-effective.

RESUMEN

BACKGROUND: Population-based cancer survival is a key metric of the effectiveness of health systems in managing cancer. Data from population-based cancer registries are essential for producing reliable and robust cancer survival estimates. Georgia established a national population-based cancer registry on 1 January 2015. This is the first analysis of population-based cancer survival from Georgia. METHODS: Data were available from the national cancer registry for 16,359 adults who were diagnosed with a cancer of the stomach, colon, rectum, breast (women) or cervix during 2015-2019. We estimated age-specific and age-standardised net survival at one, two and three years after diagnosis for each cancer, by sex. RESULTS: The data were of extremely high quality, with less than 2% of data excluded from each dataset. For the patients included in analyses, at least 80% of the tumours were microscopically verified. Age-standardised three-year survival from stomach cancer was 30.6%, similar in men and women. For colon cancer, three-year survival was 60.1%, with survival 4% higher for men than for women. Three-year survival from rectal cancer was similar for men and women, at 54.7%. For women diagnosed with breast cancer, three-year survival was 84.4%, but three-year survival from cervical cancer was only 67.2%. CONCLUSION: Establishment of a national cancer registry with obligatory cancer registration has enabled the first examination of population-based cancer survival in Georgia. Maintenance of the registry will facilitate continued surveillance of both cancer incidence and survival in the country.

RESUMEN

OBJECTIVES: Georgia has a high prevalence of hepatitis C virus (HCV) infection. In 2015 a national HCV elimination program was launched providing free access to screening and treatment. To achieve elimination, innovative approaches to increase screening coverage and linkage to care are needed. This study estimates feasibility, acceptability, and outcomes of the door-to-door pilot HCV testing program in three cities. METHODS: Households were approached by system random sampling and all members were invited for study participation. Researchers used a detailed guide for conducting door-to-door testing and served as case navigators to link anti-HCV-positive individuals to care. RESULTS: Testing acceptance rate was high. In total 4804 individuals were tested and 48 (1.0%) were HCV positive. Among the entire sample of newly and previously tested individuals, overall HCV antibody prevalence was 3.6%. Through case navigation, of 48 newly identified and 26 previously identified anti-HCV-positive individuals, 42 (87.5%) and 17 (65.4%), respectively, were successfully linked to care. CONCLUSIONS: Door-to-door HCV testing has potential to increase testing uptake. Such community-based approaches not only improve testing, but can also serve to increase linkage to care, which is important in achieving the goal of HCV elimination. The study provides a model for high prevalence countries aiming to eliminate hepatitis C.

RESUMEN

BACKGROUND AND AIMS: In 2015, Georgia began a hepatitis C virus (HCV) elimination programme. Although screening programmes have been decentralized for high-risk groups, viraemic testing remains a bottleneck for people who inject drugs. Here, we describe two models of viraemic testing that aimed to address this gap. METHODS: We assigned eight harm reduction sites (HRS) to one of three arms (2,1:1): Xpert HCV viral load testing on-site, blood draw on-site with centralized HCV core antigen testing (HCVcAg), or standard-of-care (SOC) referral with viremia testing performed at treatment centres. RESULTS: 1671 HCV-seropositive participants were enrolled (Xpert, 37.1%; HCVcAg, 29.1%; referral, 33.8%). Participants were predominantly male (95.4%), mean age (IQR) 43 (37, 50) years and 1290 (77.2%) were currently injecting drugs. Significantly higher proportions of participants in the Xpert (100%) and HCVcAg (99.8%) arms received viraemia testing compared with the referral arm (91.3%) (Xpert vs referral, p < 0.0001; HCVcAg vs referral, p < 0.0001). Among viraemic participants, treatment uptake was similar (Xpert, 84.0%; HCVcAg, 79.5%; referral, 88.4%). The time between screening and sample collection for viraemia testing was significantly longer in the referral arm compared with both Xpert and HCVcAg arms (median 1 day compared with 0 days respectively), and the overall time between screening to treatment initiation was longer for the referral arm (median 67 days) compared with both Xpert and HCVcAg arms (median 57 and 50 days respectively). CONCLUSIONS: Point-of-care viraemia testing and blood drawn on-site for HCVcAg testing yielded more HCV-seropositive patients receiving viraemic testing within a shorter timeframe compared with referrals.

RESUMEN

Detection and epidemiologic characterization of infectious disease outbreaks are key for early identification and response to potential pandemic threats. The rapid global spread of severe SARS-CoV-2 in 2020 highlighted the critical role of diagnostics in understanding the epidemiology of the virus early in the pandemic. As a natural extension of Abbott's work in diagnostics, virus discovery, and virus surveillance, the Abbott Pandemic Defense Coalition (APDC) was launched in early 2021. The APDC is a global multisector scientific and public health partnership whose primary objective is the early detection and mitigation of infectious disease threats of pandemic potential. As of January 2022, the APDC network has partners on 5 continents including academic institutions, governmental, and nongovernmental organizations. A novel element of the APDC is the capacity for early development and rapid deployment of scalable, quality diagnostics targeting newly identified pathogens of pandemic potential.

RESUMEN

In preparation for the National Hepatitis C Elimination Program in the country of Georgia, a nationwide household-based hepatitis C virus (HCV) seroprevalence survey was conducted in 2015. Data were used to estimate HCV genotype distribution and better understand potential sex-specific risk factors that contribute to HCV transmission. HCV genotype distribution by sex and reported risk factors were calculated. We used explanatory logistic regression models stratified by sex to identify behavioral and healthcare-related risk factors for HCV seropositivity, and predictive logistic regression models to identify additional variables that could help predict the presence of infection. Factors associated with HCV seropositivity in explanatory models included, among males, history of injection drug use (IDU) (aOR = 22.4, 95% CI = 12.7, 39.8) and receiving a blood transfusion (aOR = 3.6, 95% CI = 1.4, 8.8), and among females, history of receiving a blood transfusion (aOR = 4.0, 95% CI 2.1, 7.7), kidney dialysis (aOR = 7.3 95% CI 1.5, 35.3) and surgery (aOR = 1.9, 95% CI 1.1, 3.2). The male-specific predictive model additionally identified age, urban residence, and history of incarceration as factors predictive of seropositivity and were used to create a male-specific exposure index (Area under the curve [AUC] = 0.84). The female-specific predictive model had insufficient discriminatory performance to support creating an exposure index (AUC = 0.61). The most prevalent HCV genotype (GT) nationally was GT1b (40.5%), followed by GT3 (34.7%) and GT2 (23.6%). Risk factors for HCV seropositivity and distribution of HCV genotypes in Georgia vary substantially by sex.

RESUMEN

INTRODUCTION: Globally, it is estimated that more than three-quarters of people with chronic hepatitis C virus (HCV) are unaware of their HCV status. HCV self-testing (HCVST) may improve access and uptake of HCV testing particularly among key populations such as people who inject drugs (PWID) and men who have sex with men (MSM) where HCV prevalence and incidence are high and barriers to accessing health services due to stigma and discrimination are common. METHODS AND ANALYSIS: This randomised controlled trial compares an online programme offering oral fluid-based HCVST delivered to the home with referral to standard-of-care HCV testing at HCV testing sites. Eligible participants are adults self-identifying as either MSM or PWID who live in Tbilisi or Batumi, Georgia, and whose current HCV status is unknown. Participants will be recruited through an online platform and randomised to one of three arms for MSM (courier delivery, peer delivery and standard-of-care HCV testing (control)) and two for PWID (peer delivery and standard-of-care HCV testing (control)). Participants in the postal delivery group will receive an HCVST kit delivered by an anonymised courier. Participants in the peer delivery groups will schedule delivery of the HCVST by a peer. Control groups will receive information on how to access standard-of-care testing at a testing site. The primary outcome is the number and proportion of participants who report completion of testing. Secondary outcomes include the number and proportion of participants who (a) receive a positive result and are made aware of their status, (b) are referred to and complete HCV RNA confirmatory testing, and (c) start treatment. Acceptability, feasibility, and attitudes around HCV testing and cost will also be evaluated. The target sample size is 1250 participants (250 per arm). ETHICS AND DISSEMINATION: Ethical approval has been obtained from the National Centers for Disease Control and Public Health Georgia Institutional Review Board (IRB) (IRB# 2021-049). Study results will be disseminated by presentations at conferences and via peer-reviewed journals. Protocol version 1.1; 14 July 2021. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04961723).

RESUMEN

OBJECTIVE: Continuing medical education (CME) is a vital component of health systems. Setting up a CME system is a complex task, requiring involvement of stakeholders including educators, learners, institutions and policy makers. The aim of the study was to conduct qualitative research involving multiple stakeholders to explore the perceived effectiveness and shortcomings of the CME system in Georgia, its place in the health system and potential means of improving it. DESIGN: This is a qualitative study. All data were collected using semistructured individual interviews. The questions were derived from the relevant literature. Data analysis was conducted using comparative strategy. PARTICIPANTS: We interviewed individuals from CME providers, medical establishments, the professional development board (PDB), and the Regulatory Agency for Medical and Pharmaceutical Activities. We thus interviewed 23 people (11 people from CME providers, 8 people from medical establishments, 3 PDB members and 1 person from Legal Entity under Public Law Regulatory Agency for Medical and Pharmaceutical Activities). RESULTS: Georgia has had experience of mandatory CME in the past, which had been criticised for its poor quality and bureaucratic processes. CME is viewed as an essential developmental process for medical professionals, the outcome of which is to deliver high-quality medical care. Our interviewees identified a clear need for high-quality CME courses. However, significant challenges that need to be overcome include financial barriers, doctors' attitudes to CME, a lack of CME courses in all medical specialties and relatively weak professional associations. CONCLUSION: CME is widely recognised as an essential pillar in providing quality medical care. Establishing high-quality CME requires a strategic and holistic approach. In order to ensure the sustainable and effective implementation of the CME process, we need to take into account stakeholders' interests and expectations, the socioeconomic status and development of the country, and past experiences of all relevant individuals and organisations.

RESUMEN

In recent years, reports of lead contamination have dramatically increased in Georgia. Given concerns about the exposure of children to lead (Pb), the National Multiple Indicator Cluster Survey (MICS-2018) included a blood sampling component. The results showed that 41% of the children that participated had blood Pb levels (BLL) ≥ 5 µg/dL and that BLL in children living in Western Georgia were higher than those in Eastern regions. In response to these findings, NCDC implemented written and verbal advice to the families of children who participated in the MICS-2018 on how to reduce Pb exposure. From August 2019 onwards, the state program of clinical follow-up was implemented. The design of this study was a longitudinal study. The intervention of interest was the public health advice and medical follow-up, and the outcome was defined as the difference in BLL between the MICS-2018 survey and the state program follow-up. We observed a significant overall reduction in median BLL between MICS-2018 and state program follow-up in both August 2019 and the latest results (until December 2019). However, we did not observe any significant further reduction between August and the most recent BLL results. In the Georgian setting, written and verbal communication targeting individual households, alongside home visits to the most exposed, effectively reduced BLL in children.

RESUMEN

May Measurement Month is a global campaign aimed at raising public awareness of hypertension and to improve the management of hypertension-the main risk factor for cardiovascular diseases in the population. Screening was carried out at 400 sites on a national scale. More than 500 volunteers, including physicians (80%) and students of medical universities (20%) participated in the screening. To familiarize them with the research tools and standard blood pressure (BP) measurement method, they were trained by the members of the Georgian Society of Hypertension and the National Center for Disease Control and Public Health's staff. Medical societies, health-care professionals, public health workers, social mass media, and other stakeholders were actively involved in the recruitment process. A total of 13 267 (38.5% males and 61.5% females) individuals were screened. The mean age of participants was 54.7 years (SD 15.9). All participants were Caucasian. After imputation of missing BP readings, 8510 (64.1%) were found to have hypertension, out of whom 7269 (85.4%) were aware of their condition, 7232 (85.0%) were on medication, and 1278 (15.0%) were not taking any medication. Of those taking antihypertensive medication, 34.8% had their BP controlled (<140/90 mmHg). May Measurement Month detected a high proportion of participants with hypertension, with results indicating low rates of control in Georgia.
