Longitudinal adherence to breast cancer surveillance following cancer genetic testing in an integrated health care system.

PURPOSE: Screening with mammography and breast magnetic resonance imaging (MRI) is an important risk management strategy for individuals with inherited pathogenic variants (PVs) in genes associated with increased breast cancer risk. We describe longitudinal screening adherence in individuals who underwent cancer genetic testing as part of usual care in a vertically integrated health system. METHODS: We determined the proportion time covered (PTC) by annual mammography and breast MRI for individuals with PVs in TP53, BRCA1, BRCA2, PALB2, NF1, CHEK2, and ATM. We determined time covered by biennial mammography beginning at age 50 years for individuals who received negative results, uncertain results, or with PVs in genes without specific breast cancer screening recommendations. RESULTS: One hundred and forty individuals had PVs in TP53, BRCA1, BRCA2, PALB2, NF1, CHEK2, or ATM. Among these individuals, average PTC was 48% (range 0-99%) for annual screening mammography and 34% (range 0-100%) for annual breast MRI. Average PTC was highest for individuals with PVs in CHEK2 (N = 14) and lowest for individuals with PVs in TP53 (N = 3). Average PTC for biennial mammography (N = 1,027) was 49% (0-100%). CONCLUSION: Longitudinal screening adherence in individuals with PVs in breast cancer associated genes, as measured by the proportion of time covered, is low; adherence to annual breast MRI falls below that of annual mammography. Additional research should examine screening behavior in individuals with PVs in breast cancer associated genes with a goal of developing interventions to improve adherence to recommended risk management.

Risk-reducing surgery in unaffected individuals receiving cancer genetic testing in an integrated health care system.

BACKGROUND: Germline genetic testing enables primary cancer prevention, including through prophylactic surgery. We examined risk-reducing surgeries in unaffected individuals tested for hereditary cancer susceptibly between 2010 and 2018 in the Kaiser Permanente Northwest health system. METHODS: We used an internal genetic testing database to create a cohort of individuals who received tests including one or more high-penetrance hereditary cancer susceptibility gene. We then identified, after testing, bilateral mastectomy, bilateral salpingo-oophorectomy (BSO), and total hysterectomy procedures in electronic health record and claims data through 2019. We describe surgery utilization by genetic test results and National Comprehensive Cancer Network (NCCN) guidelines. RESULTS: The cohort included 1020 individuals, 16% with pathogenic/likely pathogenic (P/LP) variants in one or more of the following genes: BRCA1, BRCA2, CHEK2, APC, MUTYH, ATM, MSH2, PALB2, BRIP1, MLH1, MSH6, EPCAM, FLCN, RAD51C, RAD51D, or TP53. Among individuals with P/LP variants making them candidates for mastectomy, BSO, or hysterectomy per NCCN guidelines, 34% (33/97), 24% (23/94), and 8% (1/12), respectively, underwent surgery during follow-up. Fifty-three percent (18/37) of hysterectomies were among APC, BRCA1, and BRCA2 P/LP variant heterozygotes, typically concurrent with BSO. Three individuals with variants of uncertain significance (only) and 22 with negative results had prophylactic surgery after genetic testing. CONCLUSIONS: Uptake of risk-reducing surgery following usual care genetic testing appears to be lower than in studies that actively recruit high-risk patients and provide testing and follow-up care in specialized settings. Factors in addition to genetic test results and NCCN guidelines motivate prophylactic surgery use and deserve further study.

ORCA, a values-based decision aid for selecting additional findings from genomic sequencing in adults: Efficacy results from a randomized trial.

PURPOSE: Individuals having genomic sequencing can choose to be notified about pathogenic variants in genes unrelated to the testing indication. A decision aid can facilitate weighing one's values before making a choice about these additional results. METHODS: We conducted a randomized trial (N = 231) comparing informed values-choice congruence among adults at risk for a hereditary cancer syndrome who viewed either the Optional Results Choice Aid (ORCA) or web-based additional findings information alone. ORCA is values-focused with a low-literacy design. RESULTS: Individuals in both arms had informed values-choice congruence (75% and 73% in the decision aid and web-based groups, respectively; odds ratio [OR] = 1.10, 95% CI = 0.58-2.08). Most participants had adequate knowledge (79% and 76% in the decision aid and web-based groups, respectively; OR = 1.20, 95% CI = 0.61-2.34), with no significant difference between groups. Most had information-seeking values (97% and 98% in the decision aid and web-based groups, respectively; OR = 0.59, 95% CI = 0.10-3.61) and chose to receive additional findings. CONCLUSION: The ORCA decision aid did not significantly improve informed values-choice congruence over web-based information in this cohort of adults deciding about genomic results. Both web-based approaches may be effective for adults to decide about receiving medically actionable additional results.

An accessible, relational, inclusive, and actionable (ARIA) model of genetic counseling compared with usual care: Results of a randomized controlled trial.

PURPOSE: Effective approaches to communicate genomic information are needed to ensure equitable care. In a randomized controlled superiority trial, we tested a novel practice model that aims to make genetic counseling inclusive, by making the communication accessible, relational, and actionable (ARIA). METHODS: In total, 696 English- and Spanish-speaking patients aged 18 to 49 years, enriched for individuals from historically underserved backgrounds, were randomized in 1:1 ratio to ARIA or usual care. Primary outcomes were accuracy of recall, communication satisfaction, and perceived understanding. In total, 33 participants completed qualitative interviews. RESULTS: Recall and understanding were high for all participants. ARIA participants scored higher on the relationship scale of communication satisfaction (mean difference = 0.09, 95% CI = <0.01 to 0.17). Moderator analyses of communication satisfaction showed that those with lower health literacy reported less communication difficulty in ARIA and those using medical interpreters reported greater communication ease in ARIA. No significant difference was found on other primary and secondary outcomes. Qualitative data enhanced understanding of how and why ARIA can be effective. CONCLUSION: This study provides evidence that a genetic counseling intervention that focuses on specific communication skills to enhance relationship-building, patient engagement, and comprehension can be effective with all patients and may be especially valuable for patients of lower health literacy and Spanish-speakers who use a medical interpreter.

Patterns of Medical Care Cost by Service Type for Patients With Recurrent and De Novo Advanced Cancer.

OBJECTIVES: There is limited knowledge about the cost patterns of patients who receive a diagnosis of de novo and recurrent advanced cancers in the United States. METHODS: Data on patients who received a diagnosis of de novo stage IV or recurrent breast, colorectal, or lung cancer between 2000 and 2012 from 3 integrated health systems were used to estimate average annual costs for total, ambulatory, inpatient, medication, and other services during (1) 12 months preceding de novo or recurrent diagnosis (preindex) and (2) diagnosis month through 11 months after (postindex), from the payer perspective. Generalized linear regression models estimated costs adjusting for patient and clinical factors. RESULTS: Patients who developed a recurrence <1 year after their initial cancer diagnosis had significantly higher total costs in the preindex period than those with recurrence ≥1 year after initial diagnosis and those with de novo stage IV disease across all cancers (all P < .05). Patients with de novo stage IV breast and colorectal cancer had significantly higher total costs in the postindex period than patients with cancer recurrent in <1 year and ≥1 year (all P < .05), respectively. Patients in de novo stage IV and those with recurrence in ≥1 year experienced significantly higher postindex costs than the preindex period (all P < .001). CONCLUSIONS: Our findings reveal distinct cost patterns between patients with de novo stage IV, recurrent <1-year, and recurrent ≥1-year cancer, suggesting unique care trajectories that may influence resource use and planning. Future cost studies among patients with advanced cancer should account for de novo versus recurrent diagnoses and timing of recurrence to obtain estimates that accurately reflect these care pattern complexities.

Retrospective assessment of barriers and access to genetic services for hereditary cancer syndromes in an integrated health care delivery system.

BACKGROUND: A critical step in access to genetic testing for hereditary cancer syndromes is referral for genetic counseling to assess personal and family risk. Individuals meeting testing guidelines have the greatest need to be evaluated. However, referrals to genetics are underutilized in US patients with hereditary cancer syndromes, especially within traditionally underserved populations, including racial and ethnic minorities, low-income, and non-English speaking patients. METHODS: We studied existing processes for referral to genetic evaluation and testing for hereditary cancer risk to identify areas of potential improvement in delivering these services, especially for traditionally underserved patients. We conducted a retrospective review of 820 referrals to the Kaiser Permanente Northwest (KPNW) genetics department containing diagnosis codes for hereditary cancer risk. We classified referrals as high- or low-quality based on whether sufficient information was provided to determine if patients met national practice guidelines for testing. Through chart abstraction, we also assessed consistency with practice guidelines, whether the referral resulted in a visit to the genetics department for evaluation, and clinical characteristics of patients receiving genetic testing. RESULTS: Most referrals (n = 514, 63%) contained sufficient information to assess the appropriateness of referral; of those, 92% met practice guidelines for genetic testing. Half of referred patients (50%) were not offered genetic evaluation; only 31% received genetic testing. We identified several barriers to receiving genetic evaluation and testing, the biggest barrier being completion of a family history form sent to patients following the referral. Those with a referral consistent with testing guidelines, were more likely to receive genetic testing than those without (39% vs. 29%, respectively; p = 0.0058). Traditionally underserved patients were underrepresented in those receiving genetic evaluation and testing relative to the overall adult KPNW population. CONCLUSIONS: Process improvements are needed to increase access to genetic services to diagnose hereditary cancer syndromes prior to development of cancer.

The influence of multi-morbidities on colorectal cancer screening recommendations and completion.

PURPOSE: Patients' chronic disease burden can influence the likelihood that providers will recommend cancer screening and that patients will participate in it. Using data from the STOP CRC pragmatic study, we examined associations between chronic disease burden and colorectal cancer screening recommendation and use. METHODS: Participating STOP CRC clinics (n = 26) received either usual care or training to implement a mailed fecal immunochemical test (FIT) outreach program. Selected clinic patients (n = 60,187 patients) were aged 50-74 and overdue for colorectal cancer screening. We used logistic regression to examine the associations between FIT recommendations and completion and patients' chronic disease burden, calculated using the Charlson Comorbidity Index and the Chronic Illness and Disability Payment System. RESULTS: For each index, FIT recommendation odds were 8-9% higher among individuals with minimal chronic disease burden and 13-23% lower among individuals with high chronic disease burden (inverted U-shaped association). Among adults who were ordered a FIT, FIT completion odds were 20% lower for individuals with any, versus no, chronic condition and diminished with increasing disease burden (inverse linear association). CONCLUSIONS: Analysis showed an inverted U-shaped association between patients' chronic disease burden and providers' recommendation of a FIT and an inverse linear association between patients' chronic disease burden and FIT completion.

Health issues and healthcare utilization among adults who reported exposure to tear gas during 2020 Portland (OR) protests: a cross-sectional survey.

BACKGROUND: Repeated use of chemical irritants for crowd-control by local and federal law enforcement during sustained racial justice protests in the U.S. has raised concerns about potential adverse health effects. The objective of this study was to describe the health consequences of exposure to tear gas agents and associated healthcare utilization among adults reporting recent exposure to tear gas. METHODS: A cross-sectional, self-administered web-based survey of a convenience sample of 2257 adults reporting recent exposure to tear gas in Portland, Oregon (U.S.), administered between July 30, 2020-August 20, 2020. Descriptive analyses were conducted on socioeconomic characteristics, reported health issues, utilization of healthcare services, and frequency of reported exposure to tear gas. Associations between reported mental health issues, healthcare utilization and race and/or ethnic categories were assessed using a chi-square test. For tests of association, racial and/or ethnic categories were divided into White/Non-Hispanic only and all other racial/ethnic categories due to a small number of Black, American Indian or Alaska Native, Asian/Pacific Islander, Hispanic participants and participants with multiple race and/or ethnic background. Effect sizes for the differences were expressed as Cramer's V, a metric that measures associations between nominal responses. The Cochran-Armitage trend test was used to assess the relationship between health issues and the number of reported days of exposure to tear gas (i.e., a proxy dose of exposure) grouped into 1 day, 2-4 days, and ≥ 5 days. Missing data (item non-response) were omitted from the analysis. RESULTS: Almost all respondents (2116; 93.8%) reported physical (2114; 93.7%) or psychological (1635; 72.4%) health issues experienced immediately after (2105; 93.3%) or days following (1944; 86.1%) the exposure. A slightly higher proportion experienced delayed head or gastrointestinal tract issues compared with immediate complaints. The majority (1233; 54.6%) reported receiving or planning to seek medical or mental care. We observed a positive exposure-response trend for all except mouth-related delayed issues (p < 0.01). CONCLUSION: Persons who reported exposer to tear gas agents also reported physical and psychological health issues over a multiple-day period. Health issues reported increased with the frequency of reported exposure, indicating a potential dose-response; these health effects often led to healthcare utilization. This study provides evidence of potential unexpected harms of tear gas in civilians.

Development of a multivariable prediction model to identify patients unlikely to complete a colonoscopy following an abnormal FIT test in community clinics.

BACKGROUND: Colorectal cancer (CRC) is the 3rd leading cancer killer among men and women in the US. The Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC) project aimed to increase CRC screening among patients in Federally Qualified Health Centers (FQHCs) through a mailed fecal immunochemical test (FIT) outreach program. However, rates of completion of the follow-up colonoscopy following an abnormal FIT remain low. We developed a multivariable prediction model using data available in the electronic health record to assess the probability of patients obtaining a colonoscopy following an abnormal FIT test. METHODS: To assess the probability of obtaining a colonoscopy, we used Cox regression to develop a risk prediction model among a retrospective cohort of patients with an abnormal FIT result. RESULTS: Of 1596 patients with an abnormal FIT result, 556 (34.8%) had a recorded colonoscopy within 6 months. The model shows an adequate separation of patients across risk levels for non-adherence to follow-up colonoscopy (bootstrap-corrected C-statistic > 0.63). The refined model included 8 variables: age, race, insurance, GINI income inequality, long-term anticoagulant use, receipt of a flu vaccine in the past year, frequency of missed clinic appointments, and clinic site. The probability of obtaining a follow-up colonoscopy within 6 months varied across quintiles; patients in the lowest quintile had an estimated 18% chance, whereas patients in the top quintile had a greater than 55% chance of obtaining a follow-up colonoscopy. CONCLUSIONS: Knowing who is unlikely to follow-up on an abnormal FIT test could help identify patients who need an early intervention aimed at completing a follow-up colonoscopy. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov ( NCT01742065 ) on December 5, 2012. The protocol is available.

Factors Affecting Adherence in a Pragmatic Trial of Annual Fecal Immunochemical Testing for Colorectal Cancer.

BACKGROUND: Colorectal cancer screening by fecal immunochemical test (FIT) reduces the burden of colorectal cancer. However, effectiveness relies on annual adherence, which presents challenges for clinic staff and patients. OBJECTIVE: Describe FIT return rates and identify factors associated with FIT adherence over 2 years in a mailed FIT outreach program in federally qualified health centers. DESIGN: Observational study nested in the Strategies and Opportunities to Stop Colon Cancer in Priority Populations (STOP CRC) trial. Five thousand one hundred ninety-five patients had an initial FIT order and were followed for ≥ 2 years (3574 also had a FIT order in the second year). MAIN MEASURES: FIT return percent in each year and patient- and neighborhood-level characteristics associated with FIT adherence. KEY RESULTS: Overall, the proportion of FIT orders that were completed was 46% in the patients' first year and 41% in the patients' second year. Of the 5195 patients with a FIT order in year 1, 3574 (69%) also had a FIT order in year 2 (71% of year 1 adherers and 67% of year 1 non-adherers, p = 0.009). Among those with a FIT order in the second year, the FIT return rate was about twice as high among those who were adherent in the first year (952/1674, or 57%) as among those who were not (531/1900, or 28%, p < 0.0001). Patient-level characteristics associated with higher odds of FIT return were a history of FIT screening at baseline, age over 65 (vs 50-65), no current tobacco use, recent receipt of a mammogram or flu vaccine, Asian ancestry (compared to non-Hispanic white), and non-English preference. The only neighborhood factor associated with lower FIT return rate was patient's larger residential city size. CONCLUSION: Our findings can inform the customization of programs to promote FIT return among patients who receive care at federally qualified health centers.

Effect of Reminding Patients to Complete Fecal Immunochemical Testing: A Comparative Effectiveness Study of Automated and Live Approaches.

BACKGROUND: The Community Preventive Services Task Force recommends multi-component interventions, including patient reminders, to improve uptake of colorectal cancer screening. OBJECTIVE: We sought to compare the effectiveness of different forms of reminders for a direct-mail fecal immunochemical test (FIT) program. DESIGN: Patient-randomized controlled trial. PARTICIPANTS: 2772 adults aged 50-75, not up to date with colorectal cancer screening recommendations, with a clinic visit in the previous year at any of four participating health center clinics. INTERVENTION: Participants were mailed an introductory letter and FIT. Those who did not complete their FIT within 3 weeks were randomized to receive (1) a reminder letter, (2) two automated phone calls, (3) two text messages, (4) a live phone call, (5) a reminder letter and a live phone call, (6) two automated phone calls and a live phone call, or (7) two text messages and a live phone call. Patients with a patient portal account were sent two email reminders, but were not randomized. MAIN MEASURES: FIT return rates for each group, 6 months following randomization. KEY RESULTS: A total of 255 (10%) participants returned their FIT within 3 weeks of the mailing. Among randomized participants (n = 2010), an additional 25.5% returned their FITs after reminders were delivered (estimated overall return rate = 32.7%). In intention-to-treat analysis, compared to the group allocated to receive a reminder letter, return rates were higher for the group assigned to receive the live phone call (OR = 1.51 [1.03-2.21]) and lower for the group assigned to receive text messages (OR = 0.66 [0.43-0.99]). Reminder effectiveness differed by language preference. CONCLUSIONS: Our data suggest that FIT reminders that included a live call were more effective than reminders that relied solely on written communication (a text message or letter).

Predictors of Colorectal Cancer Screening Prior to Implementation of a Large Pragmatic Trial in Federally Qualified Health Centers.

Colorectal cancer screening can prevent cancer deaths. Federally qualified health centers serve a unique patient population that often is not screened. Knowing who in this environment is getting screened via fecal testing and via colonoscopy can assist in tailoring intervention to raise rates of colorectal cancer screening. We examined patient-level and neighborhood-level characteristics associated with being up to date with colorectal cancer screening guidelines. We also examined associations between these factors and being screened with a fecal test. We observed an increase in colorectal cancer screening rates from 2010 to 2015. Adjusted analyses revealed that the following factors were significantly associated with colorectal cancer screening: aged 65 or older, having any type of insurance, previous outpatient visits, and current or other preventive screenings. Among adults aged 50-75 who were up to date with colorectal cancer screening, factors associated with use of fecal testing, as opposed to colonoscopy, were: being younger, speaking a non-English language, being uninsured, having prior office visits, and having had a flu shot in past year. Our findings may inform clinic-based effort to raise rates of colorectal cancer screening, especially in the community clinic setting. TRIAL REGISTRATION: ClinicalTrials.gov , NCT01742065.

All-Cause Mortality and Progression Risks to Hepatic Decompensation and Hepatocellular Carcinoma in Patients Infected With Hepatitis C Virus.

BACKGROUND: A key question in care of patients with chronic hepatitis C virus (HCV) infection is beginning treatment immediately vs delaying treatment. Risks of mortality and disease progression in "real world" settings are important to assess the implications of delaying HCV treatment. METHODS: This was a cohort study of HCV patients identified from 4 integrated health systems in the United States who had liver biopsies during 2001-2012. The probabilities of death and progression to hepatocellular carcinoma, hepatic decompensation (hepatic encephalopathy, esophageal varices, ascites, or portal hypertension) or liver transplant were estimated over 1, 2, or 5 years by fibrosis stage (Metavir F0-F4) determined by biopsy at beginning of observation. RESULTS: Among 2799 HCV-monoinfected patients who had a qualifying liver biopsy, the mean age at the time of biopsy was 50.7 years. The majority were male (58.9%) and non-Hispanic white (66.9%). Over a mean observation of 5.0 years, 261 (9.3%) patients died and 34 (1.2%) received liver transplants. At 5 years after biopsy, the estimated risk of progression to hepatic decompensation or hepatocellular carcinoma was 37.2% in stage F4, 19.6% in F3, 4.7% in F2, and 2.3% in F0-F1 patients. Baseline biopsy stage F3 or F4 and platelet count below normal were the strongest predictors of progression to hepatic decompensation or hepatocellular carcinoma. CONCLUSIONS: The risks of death and progression to liver failure varied greatly by fibrosis stage. Clinicians and policy makers could use these progression risk data in prioritization and in determining the timing of treatment for patients in early stages of liver disease.

The validation of electronic health records in accurately identifying patients eligible for colorectal cancer screening in safety net clinics.

BACKGROUND: While electronic health records (EHRs) play a key role in increasing colorectal cancer (CRC) screening by identifying individuals who are overdue, important shortfalls remain. OBJECTIVES: As part of the Strategies and Opportunities to STOP Colon Cancer (STOP CRC) study, we assessed the accuracy of EHR codes in identifying patients eligible for CRC screening. METHODS: We selected a stratified random sample of 800 study participants from 26 participating clinics, in the Pacific Northwest region of the USA. We compared data obtained through codes in the EHR to conduct a manual chart audit. A trained chart abstractor completed the abstraction of eligible and ineligible patients. RESULTS: Of 520 individuals in need of CRC screening, identified via the EHR, 459 were confirmed through chart review (positive predictive value = 88%). Of 280 individuals flagged as up-to-date in their screening per EHR data, 269 were confirmed through chart review (negative predictive value = 96%). Among the 61 patients incorrectly classified as eligible, 83.6% of disagreements were due to evidence of a prior colonoscopy or referral that was not captured in recognizable fields in the EHR. CONCLUSIONS: Our findings highlight importance of better capture of past screening events in the EHR. While the need for better population-based data is not unique to CRC screening, it provides an important example of the use of population-based data not only for tracking care, but also for delivering interventions.

Reduced emergency department use among insured individuals receiving extended-release buprenorphine in a health system setting.

Introduction: Extended-release buprenorphine (XR-Bup) is associated with reduced opioid use and opioid negative urine drug screens. Little is known about its use in outpatient addiction care provided within health systems. Methods: Individuals prescribed XR-Bup were identified from electronic health records; chart abstraction was conducted. Primary outcome was all-cause emergency department (ED) use. Secondary outcomes included ED use or inpatient stays for mental health or substance use, ED use for any other cause, discontinuation reasons, and drug substitution. Statistical comparisons used nonparametric tests from related samples (McNemar's test and Wilcoxon matched pair tests) to test outcomes six months prior and 6 months following XR-Bup initiation. Results: 152 individuals had an XR-Bup order, 126 received >1 injection. Among those consistently insured 6 months prior to and following XR-Bup initiation (n=99), the mean number of injections following initiation was 3.95; one-third received 6 doses in the 6 months. The proportion of individuals using ED services for all causes declined (41% prior vs. 28% following XR-Bup initiation, p<.05); similar results were found for secondary ED use outcomes. The proportion of individuals requiring inpatient treatment for mental health or substance use also declined (46% vs. 16%, p<.01). Common reasons for discontinuing XR-Bup included losing insurance (21%) or cost (11%). The most common non-prescribed substances used during treatment were opioids (n=31) and THC (n=20). Conclusions: In this non-randomized retrospective observational study, use of XR-Bup was associated with reduced ED use 6 months following initiation. XR-Bup may help health systems reduce use of costly ED services.

Examining the Association Between Social Needs and Care Gap Closure Among Older Adults Receiving Dental Care.

Introduction: The authors of this study sought to (1) describe the prevalence of social needs and (2) determine whether social needs were associated with closure of care gaps among patients aged ≥65 years seeking dental care. Methods: In this retrospective cross-sectional study, the authors identified 754 Kaiser Permanente Northwest patients aged ≥65 years who completed an index dental visit; had at least 1 of 23 preventive care gaps (e.g., flu vaccination) or disease management care gaps (e.g., diabetes HbA1c screening test) documented in their medical record; and had completed a social needs assessment through survey evaluating financial strain, food insecurity, housing needs, social isolation, and transportation needs. The authors described the prevalence of social needs at the index visit and then used logistic regression to evaluate the association between the number of social needs (0, 1, ≥2) and closure of all care gaps over the following 60 days (yes versus no), adjusting for patient characteristics. Identification and closure of care gap were assessed through Kaiser Permanente Northwest's Panel Support Tool. Results: Approximately 28% of patients reported ≥1 social needs. The prevalence of social needs was as follows: social isolation, 13.7%; financial strain, 11.3%; food insecurity, 7.7%; transportation needs, 5.4%; and housing needs, 3.3%. Those with 1 social need were more likely to close care gaps than those with no social needs (OR=1.82, 95% CI=1.17, 2.85). No significant association was found with care gap closure among those with ≥2 versus zero social needs. Conclusions: The prevalence of social needs was nearly 30% among patients aged ≥65 years with dental and medical coverage. Patients with 1 social need were more likely than those with no social needs to close all care gaps after their visit.

Examining the Association of Social Needs with Future Health Care Utilization in an Older Adult Population: Which Needs Are Most Important?

Abstract Social needs, such as social isolation and food insecurity, are important individual-level social determinants of health, especially for adults ages 65 years and older. These needs may be associated with future health care utilization, but this research area has not been studied extensively. The objective of this study was to examine the independent association of 5 individual social needs with future (1) emergency department (ED) visits and (2) hospital admissions. This observational study included 9649 Kaiser Permanente Northwest (KPNW) Medicare members who completed the Medicare Total Health Assessment (MTHA) quality improvement survey between August 17, 2020 and January 31, 2022. The 5 social needs assessed by the MTHA, defined as binary measures (yes/no), included (1) financial strain, (2) food insecurity, (3) housing instability, (4) social isolation, and (5) transportation needs. ED utilization (yes/no) and hospitalization (yes/no), the current study outcome measures, were measured in the 12 months after MTHA assessment. In multivariable analyses, 3 of the 5 social needs were significantly associated with higher ED utilization: financial strain (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.11-1.76, P < 0.05), housing instability (OR = 1.43, 95% CI = 1.02-1.99, P < 0.05), and social isolation (OR = 1.19, 95% CI = 1.05-1.34, P < 0.05), and 1, financial strain, was significantly associated with hospital admissions (OR = 1.66, 95% CI = 1.23-2.23, P < 0.05). The study results identified which social needs are most strongly associated with future ED utilization and hospital admissions. Further research is needed to better understand whether addressing social needs is associated with improved patient-level health outcomes over time.

Risk management actions following genetic testing in the Cancer Health Assessments Reaching Many (CHARM) Study: A prospective cohort study.

BACKGROUND: Genetic testing can identify cancer risk early, enabling prevention and early detection. We describe use of risk management interventions following genetic testing in the Cancer Health Assessment Reaching Many (CHARM) study. CHARM assessed risk and provided genetic testing to low income, low literacy, and other underserved populations that historically face barriers to accessing cancer genetic services. METHODS: CHARM was implemented in Kaiser Permanente Northwest (KPNW) and Denver Health (DH) between 2018 and 2020. We identified post-testing screening (mammography, breast MRI, colonoscopy) and surgical (mastectomy, oophorectomy) procedures using electronic health records. We examined utilization in participants who did and did not receive actionable risk management recommendations from study genetic counselors following national guidelines. RESULTS: CHARM participants were followed for an average of 15.4 months (range: 0.4-27.8 months) after results disclosure. Less than 2% (11/680) received actionable risk management recommendations (i.e., could be completed in the initial years following testing) based on their test result. Among those who received actionable recommendations, risk management utilization was moderate (54.5%, 6/11 completed any procedure) and varied by procedure (mammogram: 0/3; MRI: 2/4; colonoscopy: 4/5; mastectomy: 1/5; oophorectomy: 0/3). Cancer screening and surgery procedures were rare in participants without actionable recommendations. CONCLUSION: Though the number of participants who received actionable risk management recommendations was small, our results suggest that implementing CHARM's risk assessment and testing model increased access to evidence-based genetic services and provided opportunities for patients to engage in recommended preventive care, without encouraging risk management overuse.

The Association Between Social Isolation and Memory Loss Among Older Adults.

INTRODUCTION: Social isolation among older individuals is associated with poor health outcomes. However, less is known about the association between social isolation and memory loss, specifically among Medicare enrollees in large, integrated health care systems. METHODS: We conducted a cross-sectional, observational study. From a cohort of 46,240 Medicare members aged 65 years and older at Kaiser Permanente Northwest (KPNW) who completed a health questionnaire, we compared self-reported memory loss of those who reported feeling lonely or socially isolated and those who did not, adjusting for demographic factors, health conditions, and use of health services in the 12 months before the survey. RESULTS: Patients who reported sometimes experiencing social isolation were more likely than those who rarely or never experienced social isolation to report memory loss in both unadjusted (odds ratio [ORsometimes]: 2.56, 95% CI= 2.42-2.70, P = 0.0076) and adjusted (ORsometimes: 2.45, 95% CI= 2.32-2.60, P = 0.0298) logistic regression models. Similarly, those who reported social isolation often or always were more likely to report memory loss than those who reported rarely or never experiencing isolation in both unadjusted (ORoften/always: 5.50, 95% CI = 5.06-5.99, P < 0.0001) and adjusted logistic regression models (ORoften/always: 5.20, 95% CI = 4.75-5.68, P < 0.0001). CONCLUSIONS: The strong association between social isolation and memory loss suggests the need to develop interventions to reduce isolation and to evaluate their effects on potential future memory loss.

Identifying appropriate comparison groups for health system interventions in the COVID-19 era.

Introduction: COVID-19 has created additional challenges for the analysis of non-randomized interventions in health system settings. Our objective is to evaluate these challenges and identify lessons learned from the analysis of a medically tailored meals (MTM) intervention at Kaiser Permanente Northwest (KPNW) that began in April 2020. Methods: We identified both a historical and concurrent comparison group. The historical comparison group included patients living in the same area as the MTM recipients prior to COVID-19. The concurrent comparison group included patients admitted to contracted non-KPNW hospitals or admitted to a KPNW facility and living outside the service area for the intervention but otherwise eligible. We used two alternative propensity score methods in response to the loss of sample size with exact matching to evaluate the intervention. Results: We identified 452 patients who received the intervention, 3873 patients in the historical comparison group, and 5333 in the concurrent comparison group. We were able to mostly achieve balance on observable characteristics for the intervention and the two comparison groups. Conclusions: Lessons learned included: (a) The use of two different comparison groups helped to triangulate results; (b) the meaning of utilization measures changed pre- and post-COVID-19; and (c) that balance on observable characteristics can be achieved, especially when the comparison groups are meaningfully larger than the intervention group. These findings may inform the design for future evaluations of interventions during COVID-19.
