Barriers to colorectal cancer screening in Latino and Vietnamese Americans

OBJECTIVE: To identify current colorectal cancer (CRC) screening practices and barriers to screening in the Latino, Vietnamese, and non-Latino white populations. METHODS: We conducted a telephone survey of Latino, non-Latino white, and Vietnamese individuals living in San Jose, California. We asked about demographics, CRC screening practices, intentions to be screened, and barriers and facilitators to screening. RESULTS: Seven hundred and seventy-five individuals (40% white, 29.2% Latino, and 30.8% Vietnamese) completed the survey (Response Rate 50%). Overall, 23% of respondents reported receipt of fecal occult blood test (FOBT) in the past year, 28% reported sigmoidoscopy (SIG) in the past 5 years, and 27% reported colonoscopy (COL) in the past 10 years. Screening rates were generally lower in Latinos and Vietnamese. Vietnamese were less likely than whites to have had SIG in the past 5 years (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.09 to 0.72), but ethnicity was not an independent predictor of FOBT or COL. Only 22% of Vietnamese would find endoscopic tests uncomfortable compared with 79% of whites (P <.05). While 21% of Latinos would find performing an FOBT embarrassing, only 8% of whites and 3% of Vietnamese felt this way (P <.05). Vietnamese were more likely than whites to plan to have SIG in the next 5 years (OR, 2.24; 95% CI, 1.15 to 4.38), but ethnicity was not associated with planning to have FOBT or COL. CONCLUSIONS: Rates of CRC screening are lower in ethnic minority populations than in whites. Differences in attitudes and perceived barriers suggest that culturally tailored interventions to increase CRC screening will be useful in these populations     

Promoting use of colorectal cancer screening tests

BACKGROUND: Colorectal cancer (CRC) screening is underutilized despite evidence that screening reduces mortality. OBJECTIVE: To assess the effect of an intervention targeting physicians and their patients on rates of CRC screening. DESIGN: A randomized clinical trial of community physicians and their patients. PARTICIPANTS: Ninety-four community primary care physicians randomly assigned to an intervention consisting of academic detailing and direct mailings to patients or a control group. Patients aged 50 to 79 years in the intervention group physicians received a letter from their physician, a brochure on CRC screening, and a packet of fecal occult blood test (FOBT) cards. MEASUREMENTS: After 1 year we measured receipt of the following: (1) FOBT in the past 2 years, (2) flexible sigmoidoscopy (SIG) or colonoscopy (COL) in the previous 5 years, and (3) any CRC screening. We report the percent change from baseline in both groups. RESULTS: 9,652 patients were enrolled for 2 years, and 3,732 patients were enrolled for 5 years. There was no increase in any CRC screening that occurred in the intervention group for patients enrolled for 2 years (12.7 increase vs 12.5%, P=.51). Similar results were seen for any CRC screening among patients enrolled for 5 years (9.7% increase vs 8.6%, P=.45). The only outcome on which the intervention had an effect was on patient rates of screening SIG (7.4% increase vs 4.4%, P<.01). CONCLUSION: With the exception of an increase in rates of SIG in the intervention group, the intervention had no effect on rates of CRC screening. Future interventions should assess innovative approaches to increase rates of CRC screening.     

Diabetes mellitus is an independent risk for gastroesophageal reflux disease among urban African Americans

An association between gastroesophageal reflux disease (GERD) and diabetes mellitus (DM) has been reported. Studies have not been population‐based and have failed to include a representative sample of African American subjects. The aim of the study was to determine if DM is independently associated with GERD among urban African Americans. Single‐center, population‐based survey utilizing a complex, stratified sampling design. To obtain a simple random sample of the entire African American community, targeted survey zones and hand‐delivered invitations were identified. Participating subjects had to be self‐described African American, age ≥18. Surveys were completed at a computer terminal assisted by a research coordinator. Four hundred nineteen subjects (weighted sample size of 21 264 [20 888–23 930]). GERD prevalence was 23.7% (95% confidence interval [CI] 23.2–23.9). GERD prevalence was 41.5 % in those with DM versus 20.6 % for those without (P < 0.001). Those with GERD had DM longer but had lower glycohemoglobin levels. The prevalence of ≥2 DM comorbidities was higher in those with GERD (odds ratio [OR] = 2.06; 95% CI 1.71–2.48). In the final model, age >40, DM, increasing body mass index, harmful drinking, and increasing smoking dependence were independently associated with GERD. For DM, there was significant effect modification by gender. In males, the risk was (OR = 4.63; 95% CI 3.96–5.40), while in females, the risk was markedly attenuated (OR = 1.79; 95% CI 1.61–2.00). Among urban African Americans, there is an independent association between DM and GERD that appears to be stronger in men. More information is needed to understand this association.     

Surveillance interval of endoscopic examinations for colorectal cancer screening

Background: There have been a few evidence‐based studies concerning the relationship between the length of the surveillance interval of colonoscopic examinations and the risk of colorectal cancer (CRC). The aim of the present study was to assess the appropriate interval between endoscopic examinations for CRC screening in a retrospective cohort study. Methods: The cohort included subjects in whom cancer was not detected at the initial endoscopic examination and in whom endoscopic examination(s) was subsequently performed one or more times. The results of the endoscopic examinations performed in the mass screening for CRC between November 1983 and March 1999 were analyzed. The study end point was the detection of CRC and the detection rates of cancer were assessed among those who underwent examinations at various intervals between successive endoscopic examinations. Results: Among the 117 636 cohort subjects, 63 invasive cancer cases and 112 mucosal cancer cases were found. The odds ratio (OR) for invasive cancer was not significantly elevated even when the interval between successive examinations was over 5 years. The OR for mucosal or invasive cancer was significantly elevated among the subjects in whom the interval between successive examinations was over 5 years (OR, 1.71; 95% confidence interval (CI), 1.07–2.73), than among those in whom the interval was 1 year. Conclusions: Since prolongation of the interval between endoscopic examinations of up to 5 years did not result in any change in the cancer risk among persons who are at average risk for CRC, 5 years may be an adequate interval between endoscopic examinations in the mass screening for CRC.     

Gut microbiome profiling and colorectal cancer in African Americans and Caucasian Americans

AIM To determine whether and to what extent the gut microbiome is involved in regulating racial disparity in colorectal cancer(CRC). METHODS All patients were recruited and experiments were performed in accordance with the relevant guidelines and regulations by the Institutional Review Boards (IRB), committees of the John D. Dingell VAMC and Wayne State University guidelines. African American (AA) and Caucasian American (CA) patients were scheduled for an outpatient screening for colonoscopy, and no active malignancy volunteer patients were doubly consented, initially by the gastroenterologist and later by the study coordinator, for participation in the study. The gut microbial communities in colonic effluents from AAs and CAs were examined using 16 sRNA profiling, and bacterial identifications were validated by performing SYBR-based Real Time PCR. For metagenomic analysis to characterize the microbial communities, multiple software/tools were used, including Metastats and R statistical software.RESULTS It is generally accepted that the incidence and mortality of CRC is higher in AAs than in CAs. However, the reason for this disparity is not well understood. We hypothesize that the gut microbiome plays a role in regulating this disparity. Indeed, we found significant differences in species richness and diversity between AAs and CAs. Bacteroidetes was more abundant in AAs than in CAs. In particular, the pro-inflammatory bacteria Fusobacterium nucleatum and Enterobacter species were significantly higher in AAs, whereas probiotic Akkermansia muciniphila and Bifidobacterium were higher in CAs. The polyphyletic Clostridia class showed a divergent pattern, with Clostridium XI elevated in AAs, and Clostridium IV, known for its beneficial function, higher in CAs. Lastly, the AA group had decreased microbial diversity overall in comparison to the CA group. In summary, there were significant differences in pro-inflammatory bacteria and microbial diversity between AA and CA, which may help explain the CRC disparity between groups.CONCLUSION Our current investigation, for the first time, demonstrates microbial dysbiosis between AAs and CAs, which could contribute to the racial disparity of CRC.     

Attitudes toward colorectal cancer screening tests

OBJECTIVE: To examine patient and physician preferences in regard to 5 colorectal cancer screening alternatives endorsed by a 1997 expert panel, determine the impact of patient and physician values regarding certain test features on screening preference, and assess physicians' perceptions of patients' values. DESIGN: Cross-sectional survey. SETTING: A general internal medicine practice at an academic medical center in 1998. PARTICIPANTS: Patients (N=217; 76% response rate) and physicians (N=39; 87% response rate) at the study setting. MEASUREMENTS AND MAIN RESULTS: Patients preferred fecal occult blood testing (43%) or colonoscopy (40%). In patients for whom accuracy was the most important test feature, colonoscopy (62%) was the preferred screening method. Patients for whom invasive test features were more important preferred fecal occult blood testing (76%; P <.001). Patients and physicians were similar in their values regarding the various test features. However, there was a significant difference between physicians' perceptions of which test features were important to patients compared with the patients' actual responses (P <.001). The largest discrepancy was for accuracy (patient actual 54% vs physician opinion 15%) and discomfort (patient actual 15% vs physician opinion 64%). CONCLUSIONS: Patients have distinct preferences for colorectal cancer screening tests that are associated with the importance placed on certain test features. Physicians incorrectly perceive those factors that are important to patients. Physicians should incorporate patient values in regard to certain test features when discussing colorectal cancer screening with their patients and when eliciting their screening preferences.     

Aspects of colorectal cancer screening,methods, age and gender

Colorectal cancer (CRC) is, besides breast, prostate, lung and skin cancers, the most common cancer worldwide and is suitable for screening. The incidence of CRC varies considerably in different parts of the world: in well-developed countries, the incidence is between 30 and 70 per 100 000 inhabitants, whereas in less-developed countries such as sub-Saharan Africa, it is 10–20/100 000 inhabitants. Women have a lower incidence of CRC, which is usually one-third of total incidence. Several studies have shown that it is possible to decrease mortality from CRC with about 20%, which is evidenced through the data from countries with screening programmes. Though the method of choice to identify blood samples in faecal matter is under debate, the most feasible way is to perform colonoscopy. Other methods include more advanced faecal analyses, testing for mutations from CRC, sigmoidoscopy, CT colonoscopy or optical colonoscopy. Colonoscopy is in most countries not available in sufficient amount and has to be carried out with great accuracy; otherwise, lesions will be missed to identify, thus leading to complications. Gender is an issue in CRC screening, as women have about 20% fewer colorectal adenomas and CRCs, but they also have more right-sided lesions, which are more difficult to detect with tests for faecal blood since they create less blood in faeces. Thus, other strategies may have to be developed for women in order for screening to have the same effect. It is essential to introduce colorectal cancer screening in all countries together with other clinical pieces of advice such as information on smoking, obesity and exercise in order to reduce one of the most dangerous cancers.     

Population-based screening for colorectal cancer: Australian research and implementation

Australia is one of the first countries in the world to implement an organized whole-of-population screening program for colorectal cancer (CRC). Australians have made broad contributions to CRC in general ranging from primary prevention through genetics, secondary prevention and treatment, to palliation. This overview focuses on some of the contributions of direct relevance to population-based screening, stretching from technology development to population-based controlled studies and health services research. In terms of simple screening tests in a two-step screening strategy, the evidence is overwhelming that fecal immunochemical tests for hemoglobin (FITs) improve detection and are more acceptable. FIT-based screening is clearly acceptable to Australians and it has been demonstrated that a national organized screening program is feasible. In terms of benefit for Australians, with full roll out and high uptake by the population we could see the number of cases dying from CRC halved by this strategy. To this will be added the extra-screening benefits of improved diagnosis, improved treatment and improved public awareness, all benefits of other screening programs. CRC screening has progressed from a matter of irrelevance and distaste, to commonwealth government policy in the context of an organized program for all Australians.     

Attitudes and knowledge of colorectal cancer and screening in Hong Kong: A population-based study

Background: Colorectal cancer (CRC) ranks third of all cancer mortalities in Hong Kong. CRC screening can reduce mortality. However, participation in the CRC screening program depends on the knowledge and attitude of the population. The aim of this study is to investigate the knowledge and attitude towards CRC screening in the Hong Kong population. Methods: One thousand and thirty‐three patients were interviewed by telephone survey. Knowledge and attitudes were assessed by using questionnaires. Results: Only 8.9% of the respondents were able to mention that CRC was the second commonest cancer cause of death; 4.5% believed they would have a higher chance of developing CRC as compared to other cancers, and 7.4% could mention one of the screening methods. Approximately half (50.3%) were unable to identify any available screening venue. Approximately one‐third (29.5%) indicated that they would definitely join a free CRC screening program, but the percentage dropped to 7.9% when a paid screening program was offered. Some (30.4%) of the respondents had the wrong impression that they did not require CRC screening because they were asymptomatic. Multivariate analysis showed that the independent predictor for participating in free screening was the concern level of getting CRC, while that for a paid screening program was a positive family history of CRC and the concern level. The concern level was dependent on a positive family history and knowledge of CRC. Conclusion: The general population in Hong Kong had deficient knowledge of CRC and screening. Education on the impact of CRC and beneficial effects of CRC screening should be offered before launching a CRC screening program.     

Breast cancer screening use by African Americans and whites in an HMO

OBJECTIVE: To examine racial differences in breast cancer screening in an HMO that provides screening at no cost. DESIGN: Retrospective cohort study of breast cancer screening among African-American and white women. Breast cancer screening information was extracted from computerized medical records. SETTING: A large HMO in New England. PATIENTS/PARTICIPANTS: White and African-American women (N=2,072) enrolled for at least 10 years in the HMO. MAIN RESULTS: Primary care clinicians documented recommending a screening mammogram significantly more often for African Americans than whites (70% vs 64%; P<.001). During the 10-year period, on average, white women obtained more mammograms (4.49 vs 3.93; P<.0001) and clinical breast examinations (5.35 vs 4.92; P<.01) than African-American women. However, a woman’s race was no longer a statistically significant predictor of breast cancer screening after adjustment for differences in age, estimated household income, estrogen use, and body mass index (adjusted number of mammograms, 4.47 vs 4.25, P=.17; and adjusted number of clinical breast examinations, 5.35 vs 5.31, P=.87). CONCLUSIONS: In this HMO, African-American and white women obtained breast cancer screening at similar rates. Comparisons with national data showed much higher screening rates in this HMO for both white and African-American women. This project was supported by a grant from the American Cancer Society (JGE), by a Robert Wood Johnson Generalist Faculty Scholar Award (JGE), and by the Harvard Pilgrim Health Care Foundation (SF, MB)     

Beliefs, risk perceptions, and gaps in knowledge as barriers to colorectal cancer screening in older adults

OBJECTIVES: To assess beliefs and perceptions of risk about colorectal cancer (CRC) and gaps in knowledge about screening in adults aged 65 to 89.
DESIGN: A population-based survey.
SETTING: United States.
PARTICIPANTS: A total of 1,148 respondents with no history of CRC, representing an estimated population of 31.6 million persons, who were stratified according to screening behavior (up to date (n=457) vs not up to date (n=691)) and age (65–74 vs 75–89).
MEASUREMENTS: The Health Information National Trends Survey (2003) questionnaire.
RESULTS: An estimated 25% of adults aged 65 to 89 had not heard of the fecal occult blood test, 17% had not heard of sigmoidoscopy or colonoscopy, and 42% were not up to date with either screening modality. Not visiting a healthcare provider in the previous year, not knowing about tests available for colon cancer, perceiving the arrangements to be checked for detecting colon cancer to be difficult, and not having an opinion about it and its cost, were significantly associated with not being up to date (each P <.03). Persons who were not up to date were frequently unaware of the importance of CRC screening, and often reported lack of a provider's recommendation to be screened (>75%). Lack of knowledge and awareness were more prevalent in those aged 75 to 89 than those aged 65 to 74.
CONCLUSION: Lack of knowledge and awareness and the absence of a physician's recommendation to be tested might explain not being up to date with CRC screening in adults in these age groups. These findings suggest a potential value for better communication between older adults and their providers regarding screening for CRC, when appropriate.     

Comparison of colorectal cancer screening and diagnoses in HIV-positive and HIV-negative veterans

Non-AIDS defining malignancies, including colorectal cancer (CRC), are emerging as significant problems in HIV-infected people. Some data suggest that HIV-positive patients have higher incidence of CRC at younger ages than those who are HIV-negative. This investigation examined CRC rates and screening types and trends between 943 HIV-infected cases and their age, race, and gender matched HIV-negative controls (n = 943) from 1 January 2005 to 31 December 2008 at the Atlanta VA Medical Center. The most common screening type among these patients was fecal occult blood testing (FOBT), but colonoscopies were more common in the controls (16.4% for cases, 27.5% for controls; p < 0.0001). Almost half of all patients included in this analysis did not have any screening for CRC during the four years of follow-up even though average age was 55 years. Fifty-one percent of cases had at least one screening test during follow-up compared to 48% of the controls; 7.6% of the cases had a screening each of the four years compared to only 2.4% of the controls (p < 0.0001). Ten HIV-positive patients were diagnosed with CRC during the study period compared to no CRC diagnoses among controls (p = 0.0015), though there was no difference in the diagnosis of colon polyps (4.6% vs. 5.1%, p = 0.5911). These data also suggest a discrepancy in CRC incidence between race and age groups: 80% of HIV-positive cases diagnosed with CRC during the study were black and two were less than 50 years of age. Future studies will need to address whether different recommendations are needed for screening based on HIV status, younger age, or race.     

Flexible sigmoidoscopy and the changing distribution of colorectal cancer: implications for screening

BACKGROUND AND AIMS: There has been a significant proximal shift in the distribution of colorectal cancer (CRC) in Northern Ireland over recent decades. The aim of this study was to investigate the potential implications of this proximal shift in CRC distribution on the efficacy of flexible sigmoidoscopy (FS) as a screening tool. PATIENTS AND METHODS: The site distribution of 5153 CRCs was available from the Northern Ireland Colorectal Cancer Register for the period 1990-1997. Similar data on 1241 CRCs between 1976 and 1978 were available from a previous study. Data on the site reached by FS were obtained from a prospectively collected endoscopy database at one of Northern Ireland's main teaching hospitals for the period 1993-1998. RESULTS: There was a significant proximal shift in CRC distribution between the two periods (23.5% proximal to the splenic flexure between 1976 and 1978 v 36.7% between 1990 and 1997; p<0.001). The descending colon was visualised during 74.4% of FS examinations. By combining the observed extent of FS examination with CRC site distribution, it was calculated that FS could have visualised 68.8% of CRCs between 1976 and 1978 but only 56.0% between 1990 and 1997. Extrapolating these data to a Northern Ireland screening programme involving FS and faecal occult blood testing suggests that significantly more CRCs could have been detected between 1976 and 1978 than between 1990 and 1997 (51.7% v 48.2%, respectively; p=0.03). CONCLUSIONS: This study confirms the previously documented left to right shift in CRC distribution in Northern Ireland and demonstrates that if this shift continues, FS will become less successful as a screening tool than is currently predicted.     

Utility of the Asia-Pacific colorectal screening scoring system and the presence of metabolic syndrome components in screening for sporadic colorectal cancer

AIM: To determine the utility of the Asia-Pacific colorectal screening (APCS) scoring system and metabolic syndrome components in individual screening for sporadic colorectal cancer.METHODS: The subjects were patients admitted to the Peking University People’s Hospital for colonoscopy between October 2012 and July 2013. Clinical information, including patient willingness to undergo colonoscopy, medical history, endoscopic findings, histology, and other information, was collected, and the patients were grouped according to APCS scores and the presence of metabolic syndrome components. Colorectal tumor detection rates were compared between the groups.RESULTS: A total of 219 patients were included in the study, 108 were male and 111 were female, resulting in a male-to-female ratio of 1:1.03. The average age of the patients was 56.8 ± 13.7 years. According to APCS scores, 88 (40.2%) patients were included in the average-risk (AR) group, 113 (51.6%) patients were included in the moderate-risk (MR) group, and 18 (8.2%) patients were included in the high-risk (HR) group. Colorectal tumors were detected in 69 (31.5%) subjects, and the detection rates in the AR, MR, and HR groups were 15.9%, 36.3%, and 77.8%, respectively. The difference in the detection rates between the three groups was statistically significant (P < 0.01). The combined detection rate of colorectal tumors in the APCS MR and HR groups was 42.0%. However, patients in the MR and HR groups who presented with metabolic syndrome components, in particular obesity, exhibited a significantly higher colorectal tumor detection rate (59.5%) than did those without these components (19.2%, P < 0.01) and those who underwent colonoscopy because of doctor’s recommendation (36.5%, P < 0.01).CONCLUSION: The APCS scoring system can be used in individual screening for sporadic colorectal cancer. The combined use of APCS scores and the metabolic syndrome components, in particular obesity, will significantly improve the efficacy of individual colorectal cancer screening.     

Gout in African Americans

Purpose

African Americans have a substantially higher prevalence of risk factors for gout than Caucasians. The aim of the present study was to compare the risk for incident gout among African Americans and Caucasians.

Methods

Incidence rates of physician-diagnosed gout among 11,559 Caucasian men and 931 African American men aged 35 to 57 years and at high cardiovascular risk, observed for 7 years as a part of the Multiple Risk Factor Intervention Trial, were analyzed. Cox regression models were used to account for potential confounding by age, body mass index, diuretic use, hypertension and diabetes status, aspirin and alcohol consumption, and kidney disease.

Results

At baseline, after accounting for risk factors, African Americans had a 14% lower prevalence of hyperuricemia than Caucasians. Incidence of gout increased with increasing prevalence of risk factors in both Caucasians and African Americans. Ethnic disparities in incidence rates were most apparent among those without other risk factors for gout. In separate Cox regression models, after accounting for risk factors, African American ethnicity was associated with a hazard ratio of 0.78 (95% confidence interval [CI], 0.66-0.93) for physician-diagnosed gout and 0.88 (95% CI, 0.85-0.90) for incident hyperuricemia. Significant interactions were observed; the association was the strongest (hazard ratio 0.47; 0.37-0.60). These associations were unaffected by addition of serum urate as a covariate or by using alternate case definitions for gout.

Conclusions

After accounting for the higher prevalence of risk factors, African American ethnicity is associated with a significantly lower risk for gout and hyperuricemia compared with Caucasian ethnicity.     

Increase in screening for colorectal cancer in older Americans: results from a national survey

OBJECTIVES: To compare the proportions of the U.S. population aged 65 and older who underwent tests for colorectal cancer (CRC) in 2000 and 2005 to examine the effect of the change in Medicare reimbursement for screening colonoscopy that occurred in 2001. DESIGN: National population‐based survey. SETTING: United States. PARTICIPANTS: A total of 6,035 respondents to the 2000 National Health Interview Survey (NHIS) and 5,490 respondents to the 2005 NHIS aged 65 and older. MEASUREMENTS: A questionnaire was used to assess self‐reports of testing (colonoscopy, sigmoidoscopy, or home fecal occult blood test (FOBT)) for CRC. Estimates for the U.S. population were extrapolated from the survey results. To account for the complex sampling design, SUDAAN was used to calculate population sizes and proportions. RESULTS: In U.S. adults aged 65 and older, the proportion reporting up‐to‐date CRC testing increased from 39.5% in 2000 to 47.1% in 2005. By 2005, endoscopy had become more common than home FOBT for CRC screening in older adults. In 2000 and in 2005, a higher proportion of men than women were screened across all age groups and for all screening modalities. The proportion screened declined with older age. CONCLUSION: Substantial increases in CRC testing, particularly colonoscopy, followed changes in Medicare reimbursement for screening colonoscopy in adults aged 65 and older. Although nearly half of older adults were up to date with CRC tests, differences remained in the use of screening according to age and sex within this age group.     

Pain Treatment of Underserved Older African Americans

Older African Americans who experience pain are especially at high risk of underassessment and undertreatment. This study examined patterns and correlates of pain medication use: severity of pain, medical conditions, and access to care. African Americans aged 65 and older were recruited from 16 churches located in south Los Angeles (N = 400). Structured face‐to‐face interviews and visual inspection of each participant's medications were conducted. More than 39% of participants were aged 75 and older, and 65% were female. Forty‐seven percent used at least one type of pain medication. The frequency of pain medication use according to pharmaceutical class was nonopioid, 33%; opioid, 12%; adjuvant, 9%; and other drug, 8%. Seventy‐seven percent of nonopioids were nonsteroidal anti‐inflammatory drugs (NSAIDs), which 25% of participants with hypertension, 28% with stroke, 26% with kidney disease, and 28% with gastrointestinal problems used. Ninety‐eight percent of participants who used NSAIDs, 98% experienced potentially inappropriate medication (PIM) use, 69% experienced drug duplication, and 65% experienced drug–drug interactions. This study suggests severe mismanagement of pain in underserved older African Americans, particularly those with comorbidity, multiple providers, and limited access to health care. The use of pain medication was associated with drug–drug interactions, drug duplication, and PIM use. The data show that many participants with severe pain are not taking pain medication or experience PIM use. One in four participants was taking NSAIDs, which can cause serious side effects in older African Americans with multiple chronic conditions.
