Prevalence of Inflammatory Bowel Diseases in Puerto Rico: A Health Care Claims Analysis of an Insured Population.

OBJECTIVE: Inflammatory Bowel Disease has increased in Hispanics. This study estimates its prevalence in Puerto Rico for 2013 and compares it with prior reports. METHODS: The database of commercial and government insurance claims of the Department of Health for 2013 was used. A case was defined as having at least two medical claims of outpatient services or one or more hospitalizations and emergency department visits with an ICD-9 code for Crohn's disease or ulcerative colitis. Cases with codes for both were classified as undetermined inflammatory bowel disease. Prevalence was calculated for inflammatory bowel disease, Crohn's disease, and ulcerative colitis overall and by age, sex, and health insurance. RESULTS: 5,378 persons were classified as having inflammatory bowel disease, for an overall prevalence of 181.54/100,000. Of these, 2,154 had Crohn's disease and 2,689 had ulcerative colitis, with prevalences of 72.71 and 90.77/100,000 respectively. Crohn's disease was more prevalent in males and ulcerative colitis in females. Both types were more prevalent in the government insured population. 719 children had inflammatory bowel disease, for a prevalence of 89.8/100,000. Of these, 480 were classified as Crohn´s disease and 169 as ulcerative colitis. Prevalences for pediatric Crohn's disease and ulcerative colitis were 60.0 and 21.2/100,000 respectively. CONCLUSION: When compared with a report for 2005, the prevalence for inflammatory bowel disease in Puerto Rico for 2013 showed a 4-fold increase overall and a 3-fold increase in children. Inflammatory bowel disease was more prevalent in government-insured as opposed to commercially insured persons, in contrast with previous findings.

Scientometric analysis of the Puerto Rico Clinical and Translational Research Consortium (PRCTRC) research publications, 2010-2018.

We analyzed the publication productivity supported by the Puerto Rico Consortium for Clinical and Translational Research (PRCTRC) using the structured process of scientometrics. The objective of this study was to evaluate the impact of the research and collaborations as presented in publications. Manuscripts published from 2010 to 2018 and that had the PRCTRC award number and a PMCID number were retrieved from the Science Citation Index database. Scientometric indicators included h-index (HI), average citation (AC), collaboration coefficient (CC), collaboration index (CI), and degree of collaboration (DC) analysis, and relative citation ratio (RCR) was done with Web of Science Platform, iCite, and Stata software. Joinpoint Trend Analysis Software was used to calculate the annual percent change (APC). From 2010 to 2018, 341 publications were identified with an average of 38 publications per year and a total of 3569 citations excluding self-citations. A significant growth (APC: 17.76%, P < 0.05) of scientific production was observed. The overall HI was 31, and the AC per item was 11.04. The overall CC was 0.82, the CI was 8.59, and the DC was 99.1%. This study demonstrates a statistically significant increase in the PRCTRC scientific production. Results allow for the assessment of the progress resulting from the provided support and to plan further strategies accordingly.

Association between Health Care Utilization with Asthma Control Levels among a Sample of Adult Patients in Puerto Rico.

OBJECTIVE: Asthma is an important and serious public health problem in Puerto Rico; however, very few studies measuring the association between health care utilization and asthma control levels in adult asthma patients in Puerto Rico have been done. METHODS: This study is secondary analysis of an observational and cross-sectional database generated by the Latin American Asthma Insights and Management (LA AIM) survey. Our sub-sample consisted of adults 18 years or older living with asthma, representing a total of 343 individuals. This study determined the numbers of ambulatory physician visits, emergency visits to a physician or an emergency room, and hospitalizations that took place the 12 months prior to the survey. Patients were characterized as having well-controlled, partly controlled, or uncontrolled asthma. Descriptive and inferential statistics were performed to detect differences in the mean and number of events for physician visits, emergency visits, and hospitalizations by asthma control groups. RESULTS: After adjusting for age, sex, and chronic health conditions (other than asthma), adult asthma patients with controlled asthma had 92.0% fewer physician visits, 82.5% fewer emergency visits, and 92.2% fewer hospitalizations than did those with uncontrolled asthma. CONCLUSION: Interventions geared toward controlling asthma symptoms and clinical manifestations in adults asthma patients-which interventions might include strategies for controlling environmental risk factors, increasing patient and family education with regard to asthma management, and boosting the use of appropriate and effective medications-may have significant potential in terms of reducing the direct and indirect costs of asthma, costs that have a critical impact on the whole health care system.

Survival from anal cancer among Hispanics-Puerto Rico, 2000-2007.

PURPOSE: The incidence of anal cancer is increasing, particularly among HIV and men who have sex with men (MSM) groups. The vast majority of cases are associated with human papillomavirus (HPV), the most common sexually transmitted infection. Epidemiological studies have also documented low survival, which might be linked to lack of appropriate screening, access, and utilization of pertinent health care services. Our objective was to assess the relative survival (1 and 3 years) of anal cancer in Puerto Rico for men and women during the period from 2000-2007. METHODS: All histological types of cancer of anus, anal canal, and anorectum (ICD-O-3 codes C210-C218), except for sarcomas, were included. Relative survival was estimated with the use of life tables from the population of Puerto Rico. In addition, the excess survival was compared by age at diagnosis, histology, and stage (defined as local, regional, or distant), using the Poisson regression model. RESULTS: The overall 3-year relative survival in Puerto Rico was the same (53 %) for men and women. CONCLUSIONS: Our findings establish baseline survival data for anal cancer in Hispanics from Puerto Rico. Since now, the national guidelines for anal cancer screening and treatment are on their way to be determined; baseline information about survival will allow monitoring the efficacy that standardized screening programs may eventually have in increasing anal cancer survival in this population.

Anal cancer incidence and mortality in Puerto Rico.

OBJECTIVE: Anal cancer is a rare tumor that is associated with oncogenic HPV genotypes. This study aims to compare the age-standardized rates (ASRs) of anal cancer incidence and mortality in men and women living in Puerto Rico (PR) with those of non-Hispanic whites (NHW), non-Hispanic blacks (NHB), and Hispanics (USH) living in the continental United States (US). METHODS: ASRs were calculated based on cancer data that came from the PR Cancer Central Registry and from the Surveillance, Epidemiology, and End Results (SEER) program. The age-specific relative risks (RR) and 95% Confidence Interval (95% CI) were estimated using Poisson regression models. RESULTS: Comparing the period of 2001 to 2004 to that of 1992 to 1996, the incidence of anal cancer increased among NHW, NHB, and PR men. In females, an increase in the incidence was observed for all racial groups except for Puerto Rican women. When evaluating findings by age groups, Puerto Rican men younger than 60 years old had a 20% higher incidence of anal cancer than did USH men of the same age strata (RR: 2.20; 95% CI = 1.48-3.29). However, Puerto Rican females had a lower incidence of anal cancer than NHW and NHB women. An increased percent change in mortality was observed only in NHW and NHB men. A decreasing trend was observed in all racial/ethnic groups except for NHW women. CONCLUSION: Our results support the notion that there are racial/ethnic differences in anal cancer incidence and mortality, with potential disparities among men and women in PR compared with USH men and women. Given the increasing incidence trends in anal cancer, particularly among PR, NHW, and NHB men, further investigation is needed to better elucidate screening practices that can aid in the prevention of anal cancer.

Penile Cancer Disparities in Puerto Rican Men as compared to the United States Population

This study compares incidence and mortality of penile cancer in Puerto Rico (PR) with other racial/ethnic groups in the United States (US) and evaluates the extent in which socioeconomic position index (SEP) or its components influence incidence and mortality in PR.

Age-standardized rates were calculated for incidence and mortality based on data from the PR Cancer Registry and the US National Cancer Institute's Surveillance, Epidemiology and End Results program, using the direct method.

PR men had approximately 3-fold higher incidence of penile cancer as compared to non-Hispanic white (Standardized rate ratio [SRR]: 3.33; 95%CI=2.80-3.95). A higher incidence of penile cancer was also reported in PR men as compared to non-Hispanic blacks and Hispanics men. Mortality from penile cancer was also higher for PR men as compared to all other ethnic/racial groups. PR men in the lowest SEP index had 70% higher incidence of penile cancer as compared with those PR men in the highest SEP index. However, the association was marginally significant (SRR: 1.70; 95%CI=0.97, 2.87). Only low educational attainment was statistically associated with higher penile cancer incidence (SRR: 2.18; 95%CI=1.42-3.29).

Although penile cancer is relatively uncommon, our results support significant disparities in the incidence and mortality rates among men in PR. Low educational attainment might influence the high incidence of penile cancer among PR men. Further studies are strongly recommended to explore these disparities. .

Prostate cancer incidence and mortality among Puerto Ricans: an updated analysis comparing men in Puerto Rico with US racial/ethnic groups.

OBJECTIVE: Prostate cancer is the most common cancer and the most common cause of cancer death among men in Puerto Rico (PR). Socioeconomic and racial/ethnic disparities with regard to prostate cancer incidence have been reported in the United States of America (US); however, detailed information regarding health disparities in PR is scarce. METHODS: Age-standardized rates for prostate cancer incidence and mortality were calculated based on the world standard population using data from the PR Central Cancer Registry and the National Cancer Institute SEER program. The age-specific relative risks were calculated using Poisson regression models. In addition, incidence and mortality rates in PR were compared by socioeconomic position (SEP) at the municipal level. RESULTS: For the period from 1992 to 2004, the incidence and mortality trends of prostate cancer decreased in all racial/ethnic groups except for PR men and US Hispanics (USH). Non-Hispanic whites (NHW), non-Hispanic blacks (NHB), and USH had higher incidence of prostate cancer than did PR men; however, PR men aged 85+ yrs and USH aged 45-54 yrs/85+ yrs, respectively, had higher incidences than did NHW and USH. Nonetheless, men in PR had a higher mortality than did USH and NHW. PR men aged 55-64 years with the highest SEP had a 40% higher mortality of prostate cancer than did those with the lowest SEP. CONCLUSION: Areas of concern include the higher mortality of prostate cancer in PR as compared with the USH and NHW in the US. Further research should be performed to guide the design and implementation of prostate cancer prevention and education programs that can increase early detection in PR men.

Penile cancer disparities in Puerto Rican men as compared to the United States population.

PURPOSE: This study compares incidence and mortality of penile cancer in Puerto Rico (PR) with other racial/ethnic groups in the United States (US) and evaluates the extent in which socioeconomic position index (SEP) or its components influence incidence and mortality in PR. MATERIALS AND METHODS: Age-standardized rates were calculated for incidence and mortality based on data from the PR Cancer Registry and the US National Cancer Institute's Surveillance, Epidemiology and End Results program, using the direct method. RESULTS: PR men had approximately 3-fold higher incidence of penile cancer as compared to non-Hispanic white (Standardized rate ratio [SRR]: 3.33; 95%CI=2.80-3.95). A higher incidence of penile cancer was also reported in PR men as compared to non-Hispanic blacks and Hispanics men. Mortality from penile cancer was also higher for PR men as compared to all other ethnic/racial groups. PR men in the lowest SEP index had 70% higher incidence of penile cancer as compared with those PR men in the highest SEP index. However, the association was marginally significant (SRR: 1.70; 95%CI=0.97, 2.87). Only low educational attainment was statistically associated with higher penile cancer incidence (SRR: 2.18; 95%CI=1.42-3.29). CONCLUSIONS: Although penile cancer is relatively uncommon, our results support significant disparities in the incidence and mortality rates among men in PR. Low educational attainment might influence the high incidence of penile cancer among PR men. Further studies are strongly recommended to explore these disparities.

Using a socioeconomic position index to assess disparities in cancer incidence and mortality, Puerto Rico, 1995-2004.

INTRODUCTION: Evaluation of the extent of socioeconomic inequalities in cancer incidence and mortality is essential to generate hypotheses in population health research and provides evidence for population-based strategies for comprehensive cancer control. The objective of this study was to create an area-based socioeconomic position (SEP) index to assess possible socioeconomic disparities in incidence and mortality of selected cancers in Puerto Rico. METHODS: Data for cancer incidence and mortality from 1995 to 2004 were obtained from the Puerto Rico Central Cancer Registry and the Puerto Rico Department of Health, and Puerto Rico socioeconomic data were obtained from the US Census 2000. We used principal component and factor analysis methods to construct the SEP index at the municipality level. We calculated age-adjusted incidence and mortality for each SEP area and used rate ratios to evaluate the differences by SEP. RESULTS: Incidence and mortality of cancer in Puerto Rico varied by SEP area. In general, the incidence and mortality for cancers of the esophagus and stomach were higher for municipalities with the lowest SEP; in contrast, rates for breast, colorectal, kidney, pancreas, prostate, and thyroid were higher for areas with the highest SEP. CONCLUSION: These results highlight cancer disparities in Puerto Rico by SEP level that warrant further research.

Productivity loss in Puerto Rico's labor market due to cancer mortality.

BACKGROUND: In Puerto Rico (PR), cancer is the second leading cause of death and the disease that causes most premature deaths, representing about 15% of them. Thus, premature death due to cancer decreases the productivity capacity in PR. OBJECTIVE: This study aimed to estimate the labor-market productivity loss in PR during 2004 as a result of premature mortality due to overall cancer and cause-specific cancers. METHODS: A model based in the incidence-based approach and in the human capital approach was developed to estimate the labor-market productivity loss. Economic data were obtained from the Public Use Microdata Sample (PUMS) of the PR Community Survey (PRCS). Mortality data were obtained from the Vital Statistics of the PR Department of Health. RESULTS: The productivity costs of all cancer deaths were estimated to be approximately $64 million (in constant value). The cancer deaths that contributed the most to productivity loss were lung and bronchus, colorectal, breast, and liver and intrahepatic bile duct. CONCLUSIONS: Although these results must be interpreted with caution, this study contributes to show a broader picture that includes the economic dimension of cancer in our society. These estimates imply that productivity cost due to cancer mortality have a great burden in PR. The leading cancer sites that generate most productivity losses are highly preventable or can be diagnosed early or are related to tobacco consumption. This study should be considered within the framework of future cost analyses for the development of health and cancer control policies.

Incidence and mortality of the leading cancer types in Puerto Rico: 1987-2004.

BACKGROUND: Cancer remains one of the leading causes of morbidity and mortality worldwide and is the second cause of death in Puerto Rico (PR). This article describes the incidence and the mortality from cancer in PR for the period of 1987 to 2004. METHODS: We analyzed data from the PR Central Cancer Registry and the PR Demographic Registry from 1987-2004, for the leading cancer types in men and women in PR. Age-adjusted incidence and mortality rates were estimated by sex, municipality, health region and primary site and were age-standardized to the 2000 PR population. RESULTS: Incidence rates for overall cancer remained constant in men and increased in women (APC = 0.6%, p < 0.05), while mortality rates decreased (APC = -1.0%) for both sexes. A significant increase was observed in the cancer incidence rates for colorectal cancer in men, while in women, an increase in breast, colorectal, and corpus and uterus cancer was observed. Mortality rates decreased for most of the major cancers types in both sexes, except for colorectal cancer in men which showed a significant increase (p < 0.05). CONCLUSION: The most important cancer types in PR (prostate, breast, colorectal, and lung) for both incidence and mortality are susceptible to primary prevention (eliminating or reducing risk factors) or to secondary prevention (early diagnosis) strategies. Our results are essential for the development of cancer prevention and control strategies in the Island.

Incidence trends of cervical cancer in Puerto Rico, 1987-2004.

OBJECTIVE: Cervical cancer was the leading malignancy among women in Puerto Rico when the Central Cancer Registry was first established by law in 1950. The screening program for cervical cancer in PR was initiated in 1961 when cytological laboratories were established in regional hospitals throughout the island, reaching its peak in 1973. In 2004, invasive cervical cancer ranked fifth among the top cancers in women in PR, representing 4% of all newly diagnosed cancers and 2% of all cancer-related deaths among women. The purpose of this study was to evaluate the incidence trends of cervical cancer by histology type in PR. METHODS: Cervical cancer cases (n = 3,516) diagnosed from 1987-2004 were obtained from the Puerto Rico Central Cancer Registry. Age-adjusted and age-specific incidence rates by histological type were calculated. Annual percent changes were estimated to evaluate the incidence trends from 1987 to 2004. RESULTS: From 1987 to 2004, the incidence of cervical cancer showed a downward trend (APC = -2.1%). Seventy-six percent (76.3%) of invasive cervical cancer cases were squamous cell carcinoma (SCC), 15.4% were adenocarcinoma (ADC), and 8.3% had other histologies. When histology was considered, a decreasing trend was observed for the incidence rates of SCC (APC = -3.2%, p < 0.05), with the greatest decrease being seen in women aged 60-74 (APC = -6.6%, p < 0.05). While the overall incidence rate of ADC remained stable (APC = 0.8%, p > 0.05), it increased in women aged 30-44 (APC = 3.8%, p < 0.05). CONCLUSION: Overall, the incidence rates for cervical cancer (SCC in particular), have decreased in PR. However, ADC does not present a similar decreasing trend. This trend, which is similar with other populations, could be explained, in part, by a decreasing prevalence of risk factors. Nevertheless, analysis by specific age group shows variations in the risk, which need careful consideration since they could imply changes in factors associated with each of the histological types.
