Breast and Colorectal Cancer Screening Utilization after Hurricane María and the COVID-19 Pandemic in Puerto Rico

Puerto Rico (PR) has faced environmental and public health challenges that could have significantly affected cancer screening access. Using administrative claims data from PR's Medicaid population, this study assessed trends in colorectal and breast cancer screening from 2016 to 2021, the impact of disasters in screening, and the absolute deficit in screening due to the pandemic. The monthly rates of claims were analyzed using Poisson regression. Significant reductions in breast and colorectal cancer screening utilization were observed. The colorectal cancer screening rate in 2017 was 77% lower a month after Hurricanes Irma and María [RRadj: 0.23; 95% CI: 0.20, 0.25] compared to the same time period in 2016. Breast cancer screening dropped 50% in November 2017 compared to November 2016 [RRadj: 0.50; 95% CI: 0.47, 0.54]. Prospectively, a recovery in utilization has been observed only for breast cancer screening. The results revealed that cancer screening utilization substantially declined after environmental disasters and the pandemic. These findings have potentially severe long-term implications for cancer health disparities and mortality in PR.

Abstract 801: The impact of COVID-19 on colorectal screening in Puerto Rico

INTRODUCTION: Puerto Rico has endured three major environmental and public health crises (Hurricane Irma, Hurricane Maria, the unprecedented seismic activity of January 2020) and the coronavirus disease 2019 (COVID-19) pandemic during the past 5 years. All these events might lead to an unquestionable deleterious impact in the prevention of cancer and across the cancer continuum, exacerbating cancer health disparities in the future. Cancer screening plays a critical role in early cancer detection. COVID-19 has significantly hampered screening programs in many countries’ cancer screening infrastructure and services, affecting adherence. Cancer is the leading cause of morbidity and mortality in Puerto Rico. Limited information is available about the impact the current pandemic on colorectal cancer screening. In this study, we aim to describe the impact of the COVID-19 pandemic on colorectal cancer screening in 2020 and assess if this impact varied by health regions.

METHODS: This study analyzed administrative data claims from the Public Health System of Puerto Rico which is managed by the Government of Puerto Rico through the Health Insurance Administration. The Current Procedural Terminology (CPT) codes included for this study were (81528, 82270, G0104, G0105, G0121, G0328, G0464). To assess changes in the numbers of colorectal cancer screening claims between the incurred year (2016 and 2020), Poisson regression was used. Initially, we fitted this model with only the incurred year as the predictor and offsetting the model with the annual average of total insured (univariate model). Based on this model, we estimate the magnitude of association between the number of claims and incurred year using the Prevalence Ratio (PR) of claims. Lastly, Poisson univariate regression model were used for each of the seven health regions (Ponce, Bayamón, Caguas, Mayaguez, Metro, Arecibo and Fajardo) to assess potential geographic disparities.

RESULTS: The numbers of colorectal cancer screening claims significantly decreased by 40% (PRcrude: 0.60, 95%CI: 0.59, 0.62) in 2020 when compared to 2016. However, when adjusting for claim incurred month, sex, health region and offsetting the model with the annual average of total insured, the numbers of colorectal cancer screening claims significantly decreased by 34%, (PRadj: 0.66, 95%CI: 0.64, 0.67). The numbers of colorectal cancer screening claims significantly decreased in all health regions in 2020 when compared to 2016 (p<0.05). However, the most impacted region was the Eastern region, Fajardo, with a 64% (PRFajardo crude: 0.36, 95%CI: 0.30, 0.42) significant decrease in numbers of colorectal cancer screening claims.

CONCLUSION: COVID-19 had a profound negative effect on colorectal screening in Puerto Rico. Moreover, despite the beneficiaries of this governmental health plan sharing similar sociodemographic and socioeconomic background, regional differences were observed.

Effect of linagliptin plus insulin in comparison to insulin alone on metabolic control and prognosis in hospitalized patients with SARS-CoV-2 infection

To evaluate the effect of the combination of linagliptin and insulin on metabolic control and prognosis in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and hyperglycemia. A parallel double-blind randomized clinical trial including hospitalized patients with SARS-CoV-2 infection and hyperglycemia, randomized to receive 5 mg linagliptin + insulin (LI group) or insulin alone (I group) was performed. The main outcomes were the need for assisted mechanical ventilation and glucose levels during hospitalization. Subjects were screened for eligibility at hospital admission if they were not with assisted mechanical ventilation and presented hyperglycemia, and a total of 73 patients with SARS-CoV-2 infection and hyperglycemia were randomized to the LI group (n = 35) or I group (n = 38). The average hospital stay was 12 ± 1 vs 10 ± 1 days for the I and LI groups, respectively (p = 0.343). There were no baseline clinical differences between the study groups, but the percentage of males was higher in the LI group (26 vs 18, p = 0.030). The improvements in fasting and postprandial glucose levels were better in the LI group that the I group (122 ± 7 vs 149 ± 10, p = 0.033; and 137 ± 7 vs 173 ± 12, p = 0.017, respectively), and insulin requirements tended to be lower in the LI group than the I group. Three patients in the LI group and 12 in the I group required assisted mechanical ventilation (HR 0.258, CI 95% 0.092–0.719, p = 0.009); 2 patients in the LI group and 6 in the I group died after a follow-up of 30 days (p = 0.139). No major side effects were observed. The combination of linagliptin and insulin in hospitalized patients with SARS-CoV-2 infection and hyperglycemia reduced the relative risk of assisted mechanical ventilation by 74% and improved better pre and postprandial glucose levels with lower insulin requirements, and no higher risk of hypoglycemia.

Human papillomavirus vaccine initiation and up-to-date vaccine coverage for adolescents after the implementation of school-entry policy in Puerto Rico

The human papillomavirus (HPV) vaccine has been proven effective in the prevention of infection with high-risk HPV types, which can lead to the development of six HPV-related cancers. Puerto Rico (PR) adopted a mandatory HPV vaccination school-entry policy that took effect in August 2018. While school-entry requirements are generally accepted as an effective approach for increasing vaccination rates, there are few studies that have documented their impact on improving HPV vaccination rates. The objective of this study was to evaluate the impact of the HPV school-entry policy in PR on HPV vaccine coverage. We used a pre-post natural experiment. The study population included adolescents registered in the PR Immunization Registry during 2008-2019. We calculated HPV vaccine initiation and up-to-date (UTD) vaccine coverage rates. We estimated age-standardized rates (ASR) and standardized rate ratio with 95%CI. Vaccine data corresponding to a total of 495,327 adolescents were included for analysis; 50.9% were male and 49.1% were females. After policy implementation, a marked increase in raw HPV vaccine initiation among 11- to 12-year-old adolescents was observed across years 2017 (a pre-policy year), 2018, and 2019 (58.3%, 76.3%, and 89.8%, respectively). UTD coverage also showed a moderate increase after policy implementation among 11- to 12-year-old adolescents. The gap between sexes in vaccine initiation and UTD coverage narrowed over time; the ASRs in 2019 showed an increase of 19% in initiation and 7% increase in UTD relative to 2017 for males and females combined (both significant at p<0.05). This study demonstrated evidence of improvement in HPV vaccination rates following implementation of the school-entry policy and a narrowed sex gap in vaccine rates over time in PR. Future analyses should assess how the policy continues to affect vaccine coverage in subsequent years and how the COVID-19 pandemic has impacted HPV vaccination uptake.

Underuse of Assistive Technology for Overcoming Disabilities in Daily Activities Among Community-Living Older Hispanics: Missed Opportunities

Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations.

A cross-sectional study was conducted to determine the prevalence of physical function disabilities and determine the frequency of assistive technology (AT) use among low-income older Hispanics. The prevalence of functional disabilities was 57.8%. Women were 2.86 times more likely to report a disability than men. The frequency of AT use was low. This highlights the urgent need for AT interventions to address the functional needs of older Hispanic women from low-income communities.

Sex disparities in the prevalence of physical function disabilities: a population-based study in a low-income community

BACKGROUND

Functional disability continues to be a significant public health problem that increases older adults' vulnerability to experience a diminished quality of life, loss of independence, higher healthcare costs and health services utilization, and increased risks of mortality. Thus, we aimed to study the prevalence of functional disabilities by sex according to the types of daily living activities, controlling for specific sociodemographic variables among older Hispanics from low-income communities.

METHODS

We used a cross-sectional epidemiological research design, considering a complex sampling design of households to interview adults ≥65 years living in low-income communities in Puerto Rico. Functional disability was measured by the PROMIS® Physical Function Short Form-20 T-score. The selected community was reported to have 5980 adult residents ≥65 years, according to the USA Census. The prevalence of functional disability was estimated using the logistic regression model, weighting by the effect of the sampling. Our estimated prevalence was compared between sexes using the prevalence ratio (PR), which was estimated with logistic regression models, controlling for age, income, number of chronic conditions, high and low impact of chronic conditions in functional disabilities, marital status, and sampling design.

RESULTS

We recruited 211 older Hispanics from a randomly selected sample. Their mean age was 74.4 ± 7.1 years, with female predominance (57.3%). The overall estimated prevalence of physical function disability using T-score among females was 2.70 (95% CI: 1.4, 5.1) times the estimated prevalence of physical function disability among males. Women were more likely to report functional disabilities in instrumental activities of daily living, self-care activities, and functional mobility compared to males. However, sex differences were largely explained by the presence of musculoskeletal conditions of high impact in functional disability.

CONCLUSIONS

The females in our study bear the greater burden of physical function disability in their adult age. Health policies, as well as future studies, should be targeted at reducing the burden of physical function disabilities in different types of daily activities through gender-sensitive disability self-management programs.

Abstract D047: Human papillomavirus school-entry vaccination mandate in Puerto Rico: Barriers and facilitators from the perspective of key informants

Introduction: School-entry vaccination mandates have been widely used as a mechanism to ensure high immunization coverage rates. In August 2018, Puerto Rico (PR) mandated a Human papillomavirus (HPV) vaccine school-entry policy for student’s ages 11 to 12 years. This new requirement in PR presents an opportunity to study the implementation process across a 5 years period (2018-2023). In this ongoing study, we conducted Key Informant (KI) interviews to document factors that facilitate or impede a successful HPV vaccine school policy implementation in PR. Methods: We conducted 29 KI semi-structured interviews with stakeholders in the Department of Health (DOH), school system, healthcare organizations, community-based organizations and coalitions in PR (in favor and against the school-entry policy) from July 2018 to June 2019. The interview guide included relevant domains based on the Consolidated Framework for Implementation Research, such as Intervention characteristics, Inner setting, Outer setting and Individual characteristics. We transcribed interviews, coded transcripts and analyzed data to identify emergent themes. Results: Potential facilitators of HPV policy implementation included: clear enforcement messages and use of personal anecdotes by nurses from health and school fields, the coverage of the vaccine by medical insurers, and the power of the Secretary of Health to include vaccines required for school-entry. Perceived barriers to the implementation process were: lack of communication between the DOH and the Department of Education, lack of knowledge about the HPV vaccine, uncertainty about the consistency of implementation in schools, lack of vaccine availability and disproportionate burden for regional school nurses. Other barrier to implementation mentioned included: school directors and teachers were detached from the implementation process, and lack of compliance from private health providers and public schools towards the immunization registry. Coalitions against this mandate focused their concerns on the right of parental autonomy. Recommendations from KI focused on: stricter policies to enforce this law in public schools, clear messages about the new mandate and HPV vaccine current coverage by health care insurers in PR. Moreover, KI expresses the need for more support from the DOH (technical and educational training to school principals and teachers, health promotion), and the need for increased education about the HPV vaccine and recommendations. Conclusions: Although school vaccination mandates are an evidence-based strategy for improving vaccination rates, several implementation barriers could affect the impact. Findings from this study can be used for improving policy procedures and implementation, and can inform states/territories considering adopting similar immunization policies. The information generated will help determine adaptations/modifications that may be needed for policy implementation in PR and other populations in the future.

Abstract D030: Arguments in favor and against the new HPV school entry implementation in Puerto Rico: Content analysis of online media coverage

Background: In August 2018, Puerto Rico (PR) adopted the Human papillomavirus (HPV) vaccine as a school-entry requirement for all students (male and female) 11 to 12 years old. Information about HPV shared in online media outlets may influence vaccine hesitancy, uptake, and parental decision. Before and after the requirement took effect, news coverage of this policy promoted discussions by groups in favor of the vaccine as well as the uproar of anti-vaccine groups, which may have influenced parental perceptions of the school-entry policy. Objective: This qualitative study explored arguments in favor of and against HPV vaccination and the new school-entry vaccination policy among parents, stakeholders, and coalitions in Puerto Rico. Methods: A systematic review was conducted to identify digital media reports related to the HPV vaccination policy and its implementation in PR from January 2017 to December 2018. This analysis focuses only on the codes extracted from the arguments provided by different organizations, coalitions and parents interviewed in the media. A grounded theory approach was used to identify emergent arguments discussed during this period in the news reports. ATLAS.ti 8 was used to facilitate data manipulation and retrieval. Results: Of all the quotes analyzed, 78% were coded as negative (against), 19% were positive (in favor) and only 3% were neutral towards the new HPV school-entry policy. The analysis identified emergent themes related arguments in favor of and against the HPV vaccine policy implementation. Positive arguments frequently discussed, included the following themes: 1) importance of the HPV vaccine for cancer prevention; 2) acknowledgment of sexual practices/activities in youth and 3) healthcare provider recommendation. Primary themes that emerged in arguments against the HPV school-entry policy included: 1) patient autonomy; 2) the right of parents to be informed about the vaccine; 3) lack of education regarding the efficacy of the vaccine; 4) potential risk of vaccines; and 5) pharmaceutical and economic interests. Conclusion: This study explored the most emerging arguments discussed in the media before and during the implementation of the HPV school entry policy in Puerto Rico. Most information disseminated was against this new policy. Media shared online was not balanced, which can lead to the promotion of vaccine hesitancy. Future online media coverage could expand the scope of information and provide a balanced, unbiased overview of this school-entry policy from a more comprehensive range of reliable sources.

Abstract D045: Content analysis of online media coverage of the human papillomavirus vaccine as a school-entry policy in Puerto Rico

Introduction: In August 2018, Puerto Rico (PR) adopted a Human Papillomavirus (HPV) vaccine school-entry policy, required for students, 11-12 years old. Previous research suggests that influence from media coverage and content might impact parents’ perception of vaccine efficacy, safety and willingness to vaccinate their children. We analyzed the coverage related to the implementation of the HPV vaccine in PR as a requirement for school-entry policy. Methods: A systematic review was conducted from January 2017 through December 2018. Search terms (in Spanish) included: Virus de Papiloma Humano, VPH, vacuna, vacunación contra VPH, implementación, among others. The search included 17 online websites; 34 articles were gathered, which were included if coverage of the new school entry-policy was mentioned in the content. The following steps were developed to review the content of the articles: 1) a matrix to evaluate the content of the article in relation to the school-entry policy and 2) qualitative analysis using grounded theory approach. Since headlines might promote readers’ perception, three different raters read the article title to document the sentiment (positive, negative or neutral). Fleiss’ Kappa analysis was used to assess intra-rater agreement. Results: Data from the matrix showed that 79% focused on this new school-entry mandate as a policy for cancer prevention and 61% of the news articles did not discuss the HPV doses required. Media reports highlighted the link between HPV and HPV-related cancers, mostly cervical cancer (59%). Limited information regarding other HPV-related cancers such as vaginal (18%), vulvar (20%), anal (12%), penile (21%) and oropharynx (24%) was included. In 2017, prior to policy implementation, news coverage focused mostly on the description of the school-entry policy, while 2018 coverage focused on the controversy of the school policy being mandatory. Most of the emergent themes related to the implementation of the HPV vaccine as a school-entry policy were negative, involving: 1) risk of the vaccine (safety and efficacy); 2) representative hesitancy; 3) parental autonomy; 4) right to be informed; and 5) lack of education about HPV and the vaccine. Positive content included: 1) knowledge and acceptance of the HPV vaccine for cancer prevention; 2) the importance of education and protective sexual behaviors; 3) support from coalitions, health providers and government representatives for implementation. The agreement of the headline sentiment between the three raters was fair (k= 32%; p &lt;0.01). Conclusion: Most of the media coverage about HPV in PR had limited information related to the vaccine, HPV, and HPV-related cancers. Weak concordance of the headline’s sentiments shows how different headlines influence the total impression created by a news story. In the case of HPV and this new policy, this situation could influence negatively public concerns regarding the new school-entry policy, as well as HPV vaccination rates in PR.

The combination of linagliptin, metformin and lifestyle modification to prevent type 2 diabetes (PRELLIM). A randomized clinical trial

BACKGROUND

Prediabetes is a highly prevalent health problem with a high risk of complications and progression to type 2 diabetes (T2D). The goals of this study were to evaluate the effect of the combination of lingaliptin + metformin + lifestyle on glucose tolerance, pancreatic β-cell function and T2D incidence in patients with prediabetes.

METHODS

A single center parallel double-blind randomized clinical trial with 24 months of follow-up in patients with impaired glucose tolerance plus two T2D risk factors which were randomized to linagliptin 5 mg + metformin 1700 mg daily + lifestyle (LM group) or metformin 1700 mg daily + lifestyle (M group). Primary outcomes were regression to normoglycemia and T2D incidence; glucose levels and pancreatic β-cell function were secondary outcomes.

RESULTS

Subjects were screened for eligibility by OGTT and 144 patients with prediabetes were randomized to LM group (n = 74) or M group (n = 70); 52 and 36 participants in the LM group and 52 and 27 participants in the M group, completed the 12 and 24 months of treatment, respectively; average follow-up was 17 ± 6 and 18 ± 7 months in M and LM group, respectively. Glucose levels during OGTT improved more in LM group. OGTT disposition index (DI) improved significantly better during the first months in LM group, increasing from 1·31 (95% CI: 1·14-1·49) to 2·41 (95% CI: 2.10-2.72) and to 2.07 (95% CI: 1.82-2.31) at 6 and 24 months in LM group vs from 1.21 (95% CI: 0.98-1.34) to 1.56 (95% CI: 1.17-1.95) and to 1.72 (95% CI: 1.45-1.98) at 6 and 24 months in M group (p < .05). T2D incidence was higher in M group in comparison to LM group (HR 4.0, 95% CI: 1.24-13.04, p = .020). The probability of achieving normoglycemia was higher in LM group (OR 3.26 CI 95% 1.55-6.84). No major side effects were observed during the study.

CONCLUSIONS

The combination of linagliptin, metformin and lifestyle improved significantly glucose metabolism and pancreatic β-cell function, and reduced T2D incidence in subjects with prediabetes as compared to metformin and lifestyle.

New Diagnoses among HIV+ Men and Women in Puerto Rico: Data from the HIV Surveillance System 2003-2014

OBJECTIVE

Describe the age-standardized rates of new HIV diagnoses and compare sex and time disparities using data from the HIV/AIDS Surveillance System in Puerto Rico (PR).

METHODS

The study comprises data of new HIV diagnoses of persons 13 years of age and older in PR reported from 2003-2014. Other variables included were age, sex, and health regions. We computed male to female ratio of new HIV diagnoses and assessed the trends in new HIV diagnoses using the annual percent change (APC) of the age-standardized rates (ASRs). The relative risk (RR) was estimated with 95% confidence intervals using Poisson regression models to assess the risk of new HIV diagnoses.

RESULTS

The highest HIV diagnosis rates were observed in the metropolitan area. These rates decreased overall for both sexes for the periods 2007 onward. The risk of getting a new HIV diagnosis was significantly higher among males, ranging from an increased risk of more than 50% to almost 5-fold (p<0.05). Overall, a trend was observed in the 2011-2014 period were the risk increases as the age decreases. For the 13-24 age group, we observed a significant increased risk in new HIV diagnosis of 53% in the 2011-2014 period, when compared to 2003-2006 (p<0.05).

CONCLUSION

Our findings suggest a shift in the risk of getting a HIV diagnosis from older to younger males. A possible explanation could be that HIV spread among young men that have sex with men might be increasing. Targeted prevention strategies should be implemented in this age group.

Trends in diabetes mellitus mortality in Puerto Rico: 1980-1997

OBJECTIVE

To determine the characteristics and trends of diabetes mortality among the Puerto Rican population from 1980 through 1997.

METHODS

Death certificates for Puerto Rican residents whose underlying cause of death was diabetes mellitus (ICD-9-250.0) were reviewed, and sociodemographic information was abstracted. The proportion mortality ratio (PMR) and 95% confidence intervals were calculated by gender, age group, educational level and period of time. Trend analysis in mortality was performed using a Poisson regression model.

RESULTS

A total of 26,193 deaths (5.8%) were primarily attributed to diabetes mellitus in the study period. Females accounted for 55.8% of all diabetes related deaths. Diabetes accounted for a higher proportion of deaths among persons aged 60-64 years (8.14%), persons aged 65-74 (8.12%), females (7.73%) and those with 1-6 years of education (7.08%). The PMR steadily increased from 4.55% in the 1980-85 period to 6.91% in the 1992-97 period. There was a higher mortality in male diabetic subjects aged < or = 64 than in females during the 18 year period. Between 1980 and 1991, females aged 65-74 had a higher mortality than males, however, mortality increased in males of the same age group during 1992-97. When the oldest age group (> or = 75) was examined, males had a higher mortality between 1986 and 1997, whereas females had a slightly higher rate between 1980 and 1985.

CONCLUSIONS

Our results indicate that diabetes mortality has been markedly increasing in the Puerto Rican population, primarily in persons aged 65 years or more. Further analysis is needed to evaluate the determinants of mortality in diabetes.
