RESUMEN

OBJECTIVES: To understand patient and caregiver perspectives on the experience of being screened or diagnosed with cognitive impairment to inform preventive clinical care. METHODS: Systematic review and synthesis of qualitative studies with searches in Ovid MEDLINE ALL, EBSCOHost CINAHL, and Scopus in February 2021. Included studies were assessed for quality and coded with descriptive, deductive, and inductive codes and findings were rated using GRADE-CER-qual. RESULTS: We included 15 qualitative studies representing 153 patients and 179 caregivers. Most studies involved in-depth interviews. No studies examined screening experiences for older adults presenting without cognitive function concerns; nearly all patients received a diagnosis of cognitive impairment. Seven themes emerged with moderate to high confidence. Findings showed the role of caregivers in pursuing assessment and its benefits in validating concerns and for future planning. Patients were less inclined to be evaluated, fearing judgements or social consequences from the diagnostic label. Caregivers and patients were at times frustrated with the assessment process yet believed it might result in treatments to cure or slow disease progression. CONCLUSION: Clinicians and care systems can support caregivers and patients by providing timely and informative resources to support their shared and separate motivations, needs, and concerns.

RESUMEN

Importance: Skin cancer is the most common cancer type and is a major cause of morbidity. Objective: To systematically review the benefits and harms of screening for skin cancer to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from June 1, 2015, through January 7, 2022; surveillance through December 16, 2022. Study Selection: English-language studies conducted in asymptomatic populations 15 years or older. Data Extraction and Synthesis: Two reviewers independently appraised the articles and extracted relevant data from fair- or good-quality studies; results were narratively summarized. Main Outcomes and Measures: Morbidity; mortality; skin cancer stage, precursor lesions, or lesion thickness at detection; harms of screening. Results: Twenty studies in 29 articles were included (N = 6 053 411). Direct evidence on screening effectiveness was from 3 nonrandomized analyses of 2 population-based skin cancer screening programs in Germany (n = 1 791 615) and suggested no melanoma mortality benefit at the population level over 4 to 10 years' follow-up. Six studies (n = 2 935 513) provided inconsistent evidence on the association between clinician skin examination and lesion thickness or stage at diagnosis. Compared with usual care, routine clinician skin examination was not associated with increased detection of skin cancer or precursor lesions (5 studies) or stage at melanoma detection (3 studies). Evidence on the association between clinician skin examination and lesion thickness at detection was inconsistent (3 studies). Nine studies (n = 1 326 051) found a consistent positive association between more advanced stage at melanoma detection and increasing risk of melanoma-associated and all-cause mortality. Two studies (n = 232) found little to no persistent cosmetic or psychosocial harms associated with screening. Conclusions and Relevance: A substantial nonrandomized evidence base suggests a clear association between earlier stage at skin cancer detection and decreased mortality risk. However, nonrandomized studies suggest little to no melanoma mortality benefit associated with skin cancer screening with visual skin examination in adolescents or adults and no association between routine clinician skin examination and earlier stage at melanoma detection. Evidence is inconsistent regarding whether clinician skin examination is associated with thinner melanoma lesions at detection.

RESUMEN

PURPOSE: The goal of Electronic Medical Records and Genomics (eMERGE) Phase III Network was to return actionable sequence variants to 25,084 consenting participants from 10 different health care institutions across the United States. The purpose of this study was to evaluate system-based issues relating to the return of results (RoR) disclosure process for clinical grade research genomic tests to eMERGE3 participants. METHODS: RoR processes were developed and approved by each eMERGE institution's internal review board. Investigators at each eMERGE3 site were surveyed for RoR processes related to the participant's disclosure of pathogenic or likely pathogenic variants and engagement with genetic counseling. Standard statistical analysis was performed. RESULTS: Of the 25,084 eMERGE participants, 1444 had a pathogenic or likely pathogenic variant identified on the eMERGEseq panel of 67 genes and 14 single nucleotide variants. Of these, 1077 (74.6%) participants had results disclosed, with 562 (38.9%) participants provided with variant-specific genetic counseling. Site-specific processes that either offered or required genetic counseling in their RoR process had an effect on whether a participant ultimately engaged with genetic counseling (P = .0052). CONCLUSION: The real-life experience of the multiarm eMERGE3 RoR study for returning actionable genomic results to consented research participants showed the impact of consent, method of disclosure, and genetic counseling on RoR.

RESUMEN

OBJECTIVE: Burnout, or job-related stress, affects more than half of all US physicians, with primary care physicians (PCPs) experiencing some of the highest rates in medicine. Our study analyzes national survey data to identify and prioritize workplace climate predictors of burnout among PCPs within a large integrated health system. DESIGN: Observational study of annual survey data from the Veterans Health Administration (VHA) All Employee Survey (AES) for 2013-2017. AES response rate ranged from 56 to 60% during the study period. Independent and dependent variables were measured from separate random samples. In total, 8,456 individual-level responses among PCPs at 110 VHA practice sites were aggregated at the facility level by reporting year. We used the semi-automated LASSO procedure to identify workplace climate measures that were more influential in predicting burnout and assessed relative importance using the Shapely value decomposition. PARTICIPANTS: VHA employees that self-identify as PCPs. MAIN MEASURES: Dependent variables included two dichotomous measures of burnout: emotional exhaustion and depersonalization. Independent measures included 30 survey measures related to dimensions of workplace climate (e.g., workload, leadership, satisfaction). RESULTS: We identified seven influential workplace climate predictors of emotional exhaustion and nine predictors of depersonalization. With few exceptions, higher agreement/satisfaction scores for predictors were associated with a lower likelihood of burnout. The majority of explained variation in emotional exhaustion was attributable to perceptions of workload (32.6%), organization satisfaction (28.2%), and organization support (19.4%). The majority of explained variation in depersonalization was attributable to workload (25.3%), organization satisfaction (22.9%), and connection to VHA mission (20.7%). CONCLUSION: Identifying the relative importance of workplace climate is important for the allocation of health organization resources to mitigate and prevent burnout within the PCP workplace. In a context of limited resources, efforts to reduce perceived workload and improve organization satisfaction may represent the biggest leverage points for health organizations to address physician burnout.

RESUMEN

PURPOSE: We sought to determine preferences of biobank participants whose samples were tested for clinically actionable variants but did not respond to an initial invitation to receive results. METHODS: We recontacted a subsample of participants in the Kaiser Permanente Washington/University of Washington site of the Electronic Medical Records and Genomics (eMERGE3) Network. The subsample had provided broad consent for their samples to be used for research but had not responded to one initial mailed invitation to receive their results. We sent a letter from the principal investigators with phone outreach. If no contact was made, we sent a certified letter stating our assumption that participant had actively refused. We collected reasons for declining. RESULTS: We recontacted 123 participants. Response rate was 70.7% (n = 87). Of these, 62 (71.3%) declined the offer of returned results and 25 (28.7%) consented. The most common reasons provided for refusal included not wanting to know (n = 22) and concerns about insurability (n = 28). CONCLUSION: Efforts to recontact biobank participants can yield high response. Though active refusal upon recontact was common, our data do not support assuming initial nonresponse to be refusal. Future research can work toward best practices for reconsenting, especially when clinically actionable results are possible.

RESUMEN

Importance: Colorectal cancer (CRC) remains a significant cause of morbidity and mortality in the US. Objective: To systematically review the effectiveness, test accuracy, and harms of screening for CRC to inform the US Preventive Services Task Force. Data Sources: MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials for relevant studies published from January 1, 2015, to December 4, 2019; surveillance through March 26, 2021. Study Selection: English-language studies conducted in asymptomatic populations at general risk of CRC. Data Extraction and Synthesis: Two reviewers independently appraised the articles and extracted relevant study data from fair- or good-quality studies. Random-effects meta-analyses were conducted. Main Outcomes and Measures: Colorectal cancer incidence and mortality, test accuracy in detecting cancers or adenomas, and serious adverse events. Results: The review included 33 studies (n = 10 776 276) on the effectiveness of screening, 59 (n = 3 491 045) on the test performance of screening tests, and 131 (n = 26 987 366) on the harms of screening. In randomized clinical trials (4 trials, n = 458 002), intention to screen with 1- or 2-time flexible sigmoidoscopy vs no screening was associated with a decrease in CRC-specific mortality (incidence rate ratio, 0.74 [95% CI, 0.68-0.80]). Annual or biennial guaiac fecal occult blood test (gFOBT) vs no screening (5 trials, n = 419 966) was associated with a reduction of CRC-specific mortality after 2 to 9 rounds of screening (relative risk at 19.5 years, 0.91 [95% CI, 0.84-0.98]; relative risk at 30 years, 0.78 [95% CI, 0.65-0.93]). In observational studies, receipt of screening colonoscopy (2 studies, n = 436 927) or fecal immunochemical test (FIT) (1 study, n = 5.4 million) vs no screening was associated with lower risk of CRC incidence or mortality. Nine studies (n = 6497) evaluated the test accuracy of screening computed tomography (CT) colonography, 4 of which also reported the test accuracy of colonoscopy; pooled sensitivity to detect adenomas 6 mm or larger was similar between CT colonography with bowel prep (0.86) and colonoscopy (0.89). In pooled values, commonly evaluated FITs (14 studies, n = 45 403) (sensitivity, 0.74; specificity, 0.94) and stool DNA with FIT (4 studies, n = 12 424) (sensitivity, 0.93; specificity, 0.85) performed better than high-sensitivity gFOBT (2 studies, n = 3503) (sensitivity, 0.50-0.75; specificity, 0.96-0.98) to detect cancers. Serious harms of screening colonoscopy included perforations (3.1/10 000 procedures) and major bleeding (14.6/10 000 procedures). CT colonography may have harms resulting from low-dose ionizing radiation. It is unclear if detection of extracolonic findings on CT colonography is a net benefit or harm. Conclusions and Relevance: There are several options to screen for colorectal cancer, each with a different level of evidence demonstrating its ability to reduce cancer mortality, its ability to detect cancer or precursor lesions, and its risk of harms.

RESUMEN

Current models of financial burden after cancer do not adequately define types of financial burden, moderators or causes. We propose a new theoretical model to address these gaps. This model delineates the components of financial burden as material and psychological as well as healthcare-specific (affording treatment) versus general (affording necessities). Psychological financial burden is further divided into worry about future costs and rumination about past and current financial burden. The model hypothesizes costs and employment changes as causes, and moderators include precancer socioeconomic status and post-diagnosis factors. The model outlines outcomes affected by financial burden, including depression and mortality. Theoretically derived measures of financial burden, interventions and policy changes to address the causes of financial burden in cancer are needed.

RESUMEN

Background: Patients prefer to discuss costs in the clinical setting, but physicians and teams may be unprepared to incorporate cost discussions into existing workflows. Objective: To understand and improve clinical workflows related to cost-of-care conversations. Design: Qualitative human-centered design study. Setting: 2 integrated health systems in the U.S. Pacific Northwest: a system-wide oncology service line and a system-wide primary care service line. Participants: Clinicians, clinical team members, operations staff, and patients. Measurements: Ethnographic observations were made at the integrated health systems, assessing barriers to and facilitators of discussing costs with patients. Three unique patient experiences of having financial concerns addressed in the clinic were designed. These experiences were refined after in-person interviews with patients (n = 20). Data were synthesized into a set of clinical workflow requirements. Results: Most patient cost concerns take 1 of 3 pathways: informing clinical care decision making, planning and budgeting concerns, and addressing immediate financial hardship. Workflow requirements include organizational recognition of the need for clinic-based cost-of-care conversations; access to cost and health plan benefit data to support each conversation pathway; clear team member roles and responsibilities for addressing cost-of-care concerns; a patient experience where cost questions are normal and each patient's preferences and privacy are respected; patients know who to go to with cost questions; patients' concerns are documented to minimize repetition to multiple team members; and patients learn their expected out-of-pocket costs before treatment begins. Limitation: Results may have limited generalizability to other health care settings, and the study did not test the effectiveness of the workflows developed. Conclusion: Clinic-based workflows for cost-of-care conversations that optimize patients' care experience require organizational commitment to addressing cost concerns, clear roles and responsibilities, appropriate and complete data access, and a team-based approach.

RESUMEN

BACKGROUND & AIMS: Relative risk of colorectal cancer (CRC) decreases with age among individuals with a family history of CRC. However, no screening recommendations specify less frequent screening with increasing age. We aimed to determine whether such a refinement would be cost effective. METHODS: We determined the relative risk for CRC for individuals based on age and number of affected first-degree relatives (FDRs) using data from publications. For each number of affected FDRs, we used the Microsimulation Screening Analysis model to estimate costs and effects of colonoscopy screening strategies with different age ranges and intervals. Screening was then optimized sequentially, starting with the youngest age group, and allowing the interval of screening to change at certain ages. Strategies with an incremental cost effectiveness ratio below $100,000 per quality-adjusted life year were considered cost effective. RESULTS: For people with 1 affected FDR (92% of those with a family history), screening every 3 years beginning at an age of 40 years is most cost effective. If no adenomas are found, the screening interval can gradually be extended to 5 and 7 years, at ages 45 and 55 years, respectively. From a cost-effectiveness perspective, individuals with more affected FDRs should start screening earlier and at shorter intervals. However, frequency can be reduced if no abnormalities are found. CONCLUSIONS: Using a microsimulation model, we found that for individuals with a family history of CRC, it is cost effective to gradually increase the screening interval if several subsequent screening colonoscopies have negative results and no new cases of CRC are found in family members.

RESUMEN

Importance: Pancreatic adenocarcinoma is the third most common cause of cancer death among men and women in the United States. Objective: To systematically review benefits and harms of screening for pancreatic adenocarcinoma to inform the US Preventive Services Task Force. Data Sources: MEDLINE, PubMed, and the Cochrane Collaboration Registry of Controlled Trials, from January 2002 through April 27, 2018; surveillance through March 22, 2019. Study Selection: Studies of adults with or without risk factors for pancreatic adenocarcinoma (eg, family history of pancreatic cancer, personal history of new-onset diabetes) undergoing imaging-based screening; studies of treatment for adults with screen-detected or asymptomatic pancreatic adenocarcinoma. Included study designs were randomized clinical trials, nonrandomized controlled intervention studies, diagnostic accuracy studies with a reference standard, cohort studies, and case-control studies (for evaluation of harms only). Studies consisting entirely of populations with known genetic syndromes associated with pancreatic cancer were excluded. Data Extraction and Synthesis: Two investigators independently reviewed abstracts and full-text articles and rated included studies for quality; data were quantitatively analyzed to calculate a pooled diagnostic yield and narratively synthesized. Main Outcomes and Measures: Mortality, morbidity, or quality of life; diagnostic accuracy of screening tests; any harm of screening or treatment. Results: Thirteen fair-quality prospective cohort screening studies (N = 1317) conducted predominantly in populations at high familial risk for pancreatic adenocarcinoma were included. No studies reported on the effect of screening on morbidity or mortality or on the effectiveness of treatment for screen-detected pancreatic adenocarcinoma. Although no studies evaluated the diagnostic accuracy of screening tests, all 13 studies reported the diagnostic yield. Yields ranged from 0 to 75 cases per 1000 persons in studies using endoscopic ultrasound, magnetic resonance imaging, and/or computed tomography-based screening. In total, 18 cases of pancreatic adenocarcinoma were detected in 1156 adults at increased familial risk and 0 cases were detected in 161 average-risk adults. In 8 studies (n = 675) assessing procedural harms of screening, no serious harms from initial screening were reported. Two studies (n = 271) found no evidence of psychosocial harms related to screening. Evidence of surgical harms was limited. Conclusions and Relevance: Imaging-based screening in groups at high familial risk can detect pancreatic adenocarcinoma with limited evidence of minimal harms. However, the effect of screening on morbidity and mortality in groups at high familial risk has not been studied, and no data are available in average-risk populations. There is limited evidence to assess benefits or harms of surgical intervention for screen-detected pancreatic adenocarcinoma.

RESUMEN

BACKGROUND: Cancer costs should be discussed by patients and providers, but information is not readily available. Results from recently published studies (in the last 5 years) on direct and indirect cancer costs may help guide these discussions. METHODS: The authors reviewed studies published between 2013 and 2017 that reported direct health care costs and indirect (productivity losses) costs. The annual mean total and net costs of cancer were summarized for all payers and for survivors only by age (ages 18-64 and ≥65 years), by phase of care (initial [ie, 12 months from diagnosis], continuing, and end-of-life [ie, 12 months before death]), or for recently diagnosed (within 1-2 years of diagnosis) and longer term survivors. RESULTS: For all payers combined, costs for cancers like breast, prostate, colorectal, and lung cancers were $20,000 to $100,000 in the initial phase, $1000 to $30,000 annually in the continuing phase, and ≥$60,000 in the end-of-life phase. Annual out-of-pocket costs to recently diagnosed survivors were >$1000 for medical care and time costs, approximately $2000 for productivity losses, and from $2500 to >$4000 for employment disability, depending on age. For longer term survivors, the cost of medical care was approximately $1500 for older survivors and $747 for younger survivors, time costs were $831 to $955 for older survivors and $459 to $630 for younger survivors, and productivity losses were approximately $800. Disability among long-term survivors was similar to that among short-term survivors. Limitations of the reviewed studies included older data and under-representation of higher cost cancers. CONCLUSIONS: Frequently updated cost information for all cancer types is needed to guide discussions of anticipated short-term and long-term cancer-related costs with survivors.

RESUMEN

Importance: Adolescent idiopathic scoliosis (AIS), a spinal curvature of 10° or more, is the most common form of scoliosis, with a prevalence of 1% to 3%. Curves progress in approximately two-thirds of patients with AIS before skeletal maturity, and large curves (>50°) may be associated with adverse health outcomes. Objective: To systematically review evidence on benefits and harms of AIS screening for the US Preventive Services Task Force (USPSTF). Data Sources: Cochrane Central Register of Controlled Trials, MEDLINE, ERIC, PubMed, CINAHL, and relevant systematic reviews were searched for studies published from January 1966 to October 20, 2016; studies included in a previous USPSTF report were also reviewed. Surveillance was conducted through July 24, 2017. Study Selection: Fair- and good-quality studies that evaluated the accuracy of screening children and adolescents aged 10 to 18 years for AIS, the benefits of AIS treatment, the harms of AIS screening or treatment, or long-term health outcomes. Data Extraction and Synthesis: Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. Main Outcomes and Measures: Health outcomes and spinal curvature in adolescence and adulthood, accuracy of screening for AIS, any harm of AIS screening or treatment. Results: Fourteen studies (N = 448 276) in 26 articles were included. Accuracy of AIS screening was highest (93.8% sensitivity; 99.2% specificity) in a cohort study of a clinic-based program using forward bend test, scoliometer, and Moiré topography screening (n = 306 082); accuracy was lower in cohort studies of 6 programs using fewer modalities (n = 141 161). Four controlled studies (n = 587) found evidence for benefit of bracing on curve progression compared with controls. A randomized clinical trial and a nonrandomized trial of exercise treatment (N = 184) found favorable reductions in Cobb angle of 0.67° to 4.9° in the intervention group compared with increases of 1.38° to 2.8° in the control group. Two cohort studies (n = 339) on long-term outcomes found that braced participants reported more negative treatment experience and body appearance compared with surgically treated or untreated participants. A study that combined a randomized clinical trial and cohort design (n = 242) reported harms of bracing, which included skin problems on the trunk and nonback body pains. There was no evidence on the effect of AIS screening on adult health outcomes. Conclusions and Relevance: Screening can detect AIS. Bracing and possibly exercise treatment can interrupt or slow progression of curvature in adolescence. However, there is little or no evidence on long-term outcomes for AIS treated in adolescence, the association between curvature at skeletal maturity and adult health outcomes, the harms of AIS screening or treatment, or the effect of AIS screening on adult health outcomes.

RESUMEN

Importance: Exposure to UV radiation, especially in childhood, increases skin cancer risk. Objective: To systematically review the evidence on the benefits and harms of behavioral counseling for skin cancer prevention to inform the US Preventive Services Task Force (USPSTF). Data Sources: Cochrane Central Register of Controlled Trials, MEDLINE, and PubMed were searched for studies published from January 2009 to March 31, 2016, for skin cancer prevention and from August 2005 to March 31, 2016, for skin self-examination. Surveillance in targeted publications was conducted through February 14, 2018. Studies included in previous USPSTF reports were reevaluated for inclusion. Study Selection: Fair- and good-quality studies of primary care-relevant behavioral interventions focused on improving skin cancer outcomes, intermediate outcomes, or skin cancer prevention and self-examination behaviors. Data Extraction and Synthesis: Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized but not pooled because of heterogeneity of measures. Main Outcomes and Measures: Skin cancer, sunburn, precursor skin lesions, sun protection behaviors, and any harms from interventions. Results: Twenty-one trials in 27 publications were included (N = 20 561). No studies assessed skin cancer outcomes in pediatric populations; 1 adult trial (n = 1356) promoting skin self-examination found no significant difference in participants diagnosed with melanoma in the intervention group vs the control group at 12-month follow-up (0 vs 1 diagnosis). There was no consistent improvement in prevention of sunburn for children (3 trials [n = 2508]) or adults (6 trials [n = 3959]). There were small to moderate increases in sun protection behavior in pediatric populations (6 trials [n = 4252]) and adults (12 trials [n = 13 099]) and small increases in skin self-examination in adults (11 trials [n = 7771]; odds ratios, 1.16-2.6). One of 3 trials of indoor tanning found an intervention effect; an appearance-focused intervention (n = 430) resulted in a smaller increase in mean indoor tanning sessions at 6 months in the intervention group vs the control group. Harms were rarely reported: 1 trial of skin self-examination (n = 1356) found an increase in skin procedures in the intervention group vs the control group at 6 months (8.0% vs 3.6%, P < .001) but not between 6 and 12 months (3.9% vs 3.3%, P = .50), and 1 trial (n = 217) found no between-group difference in skin cancer worry (28.9% vs 18.4%, P = .16). Conclusions and Relevance: Behavioral interventions can increase sun protection behavior, but there is no consistent evidence that interventions are associated with a reduction in the frequency of sunburn in children or adults and minimal evidence on skin cancer outcomes. Intervention can increase skin self-examination in adults but may lead to increased skin procedures without detecting additional atypical nevi or skin cancers.

RESUMEN

Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have an increased risk for CRC. An understanding of these risks, screening recommendations, and screening behaviors can inform strategies for reducing the CRC burden in these families. A comprehensive review of the literature published within the past 10 years has been performed to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening, and effective interventions in persons with an FH of CRC and to identify FH tools used to identify these individuals and inform care. Existing data show that having 1 affected first-degree relative (FDR) increases the CRC risk 2-fold, and the risk increases with multiple affected FDRs and a younger age at diagnosis. There is variability in screening recommendations across consensus guidelines. Screening adherence is <50% and is lower in persons under the age of 50 years. A provider's recommendation, multiple affected relatives, and family encouragement facilitate screening; insufficient collection of FH, low knowledge of guidelines, and poor family communication are important barriers. Effective interventions incorporate strategies for overcoming barriers, but these have not been broadly tested in clinical settings. Four strategies for reducing CRC in persons with familial risk are suggested: 1) improving the collection and utilization of the FH of cancer, 2) establishing a consensus for screening guidelines by FH, 3) enhancing provider-patient knowledge of guidelines and communication about CRC risk, and 4) encouraging survivors to promote screening within their families and partnering with existing screening programs to expand their reach to high-risk groups.

RESUMEN

IMPORTANCE: Skin cancer, primarily melanoma, is a leading cause of morbidity and mortality in the United States. OBJECTIVE: To provide an updated systematic review for the US Preventive Services Task Force regarding clinical skin cancer screening among adults. DATA SOURCES: MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials were searched for relevant studies published from January 1, 1995, through June 1, 2015, with surveillance through February 16, 2016. STUDY SELECTION: English-language studies conducted in asymptomatic populations 15 years and older at general risk for skin cancer. DATA EXTRACTION AND SYNTHESIS: Relevant data were abstracted, and study quality was rated. MAIN OUTCOMES AND MEASURES: Melanoma incidence and mortality, harms from cancer screening, diagnostic accuracy, and stage distribution. RESULTS: No randomized clinical trials were identified. There was limited evidence on the association between skin cancer screening and mortality. A German ecologic study (n = 360,288) found a decrease of 0.8 per 100,000 melanoma deaths in a region with population-based skin cancer screening compared with no change or slight increases in comparison regions. The number of excisions needed to detect 1 skin cancer from clinical visual skin examinations varied by age and sex; for example, 22 for women 65 years or older compared with 41 for women aged 20 to 34 years. In 2 studies of performing visual skin examination, sensitivity to detect melanoma was 40.2% and specificity was 86.1% when conducted by primary care physicians (n = 16,383). Sensitivity was 49.0% and specificity was 97.6% when skin examinations were performed by dermatologists (n = 7436). In a case-control study of melanoma (n = 7586), cases diagnosed with thicker lesions (>0.75 mm) had an odds ratio of 0.86 (95% CI, 0.75-0.98) for receipt of a physician skin examination in the prior 3 years compared with controls. Eight cohort studies (n = 236,485) demonstrated a statistically significant relationship between the degree of disease involvement at diagnosis and melanoma mortality, regardless of the characterization of the stage or lesion thickness. Tumor thickness greater than 4.0 mm was associated with increased melanoma mortality compared with thinner lesions, and late stage at diagnosis was associated with increased all-cause mortality. CONCLUSIONS AND RELEVANCE: Only limited evidence was identified for skin cancer screening, particularly regarding potential benefit of skin cancer screening on melanoma mortality. Future research on skin cancer screening should focus on evaluating the effectiveness of targeted screening in those considered to be at higher risk for skin cancer.

RESUMEN

IMPORTANCE: Multifactorial dyslipidemia, characterized by elevated total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C), is associated with dyslipidemia and markers of atherosclerosis in young adulthood. Screening for dyslipidemia in childhood could delay or reduce cardiovascular events in adulthood. OBJECTIVE: To systematically review the evidence on benefits and harms of screening adolescents and children for multifactorial dyslipidemia for the US Preventive Services Task Force (USPSTF). DATA SOURCES: MEDLINE, Cochrane Central Register of Controlled Trials, and PubMed were searched for studies published between January 1, 2005, and June 2, 2015; studies included in a previous USPSTF evidence report and reference lists of relevant studies and ongoing trials were also searched. Surveillance was conducted through April 9, 2016. STUDY SELECTION: Fair- and good-quality studies in English with participants 0 to 20 years of age. DATA EXTRACTION AND SYNTHESIS: Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. MAIN OUTCOMES AND MEASURES: Outcomes included dyslipidemia (TC≥200 mg/dL or LDL-C≥130 mg/dL) and atherosclerosis in childhood; myocardial infarction and ischemic stroke in adulthood; diagnostic yield (number of confirmed cases per children screened); and harms of screening or treatment. Simulated diagnostic yield was calculated as initial screening yield × positive predictive value from a study with confirmatory testing. RESULTS: Screening of children for multifactorial dyslipidemia has not been evaluated in randomized clinical trials. Based on 1 observational study (n = 6500) and nationally representative prevalence estimates, the simulated diagnostic yield of screening for elevated TC varies between 4.8% and 12.3% (higher in obese children [12.3%] and at the ages when TC naturally peaks-7.2% at age 9-11 years and 7.2% at age 16-19 years). One good-quality randomized clinical trial (n = 663) found a modest effect of intensive dietary counseling for a low-fat, low-cholesterol diet on lipid levels at 1 year in children aged 8 to 10 years with mild to moderate dyslipidemia; mean between-group difference in TC change from baseline was -6.1 mg/dL (95% CI, -9.1 to -3.2 mg/dL; P < .001). Between-group differences dissipated by year 5. The intervention did not adversely affect nutritional status, growth, or development over the 18-year study period. One observational study (n = 9245) found that TC concentration at age 12 to 39 years was not associated with death before age 55 years. CONCLUSIONS AND RELEVANCE: The diagnostic yield of lipid screening varies by age and body mass index. No direct evidence was identified for benefits or harms of childhood screening or treatment on outcomes in adulthood. Intensive dietary interventions may be safe, with modest short-term benefit of uncertain clinical significance.

RESUMEN

IMPORTANCE: Familial hypercholesterolemia (FH) is characterized by elevated cholesterol concentrations early in life. Untreated FH is associated with premature cardiovascular disease in adulthood. OBJECTIVE: To systematically review the evidence on benefits and harms of screening adolescents and children for heterozygous FH for the US Preventive Services Task Force (USPSTF). DATA SOURCES: MEDLINE, the Cochrane Central Register of Controlled Trials, and PubMed were searched for studies published between January 1, 2005, and June 2, 2015; studies included in a previous USPSTF report were also searched. Surveillance was conducted through April 8, 2016. STUDY SELECTION: Fair- and good-quality studies in English with participants 0 to 20 years of age. DATA EXTRACTION AND SYNTHESIS: Two investigators independently reviewed abstracts and full-text articles and extracted data into evidence tables. Results were qualitatively summarized. MAIN OUTCOMES AND MEASURES: Myocardial infarction and ischemic stroke in adulthood; lipid concentrations and atherosclerosis in childhood; diagnostic yield of screening; any harm of screening or treatment. RESULTS: Based on 2 studies (n = 83,241), the diagnostic yield of universal screening for FH in childhood is 1.3 to 4.8 cases per 1000 screened. There was no eligible evidence on the benefits or harms of FH screening in childhood. Eight placebo trials of statin drugs (n = 1071, 6-104 weeks) found low-density lipoprotein cholesterol (LDL-C) decreases of 20% to 40%; 1 trial (n = 214) showed a 2.01% decrease in carotid intima-media thickness with statins, compared with 1.02% with placebo (P = .02). Three placebo trials of bile acid-sequestering agents (n = 332, 8-52 weeks) showed LDL-C reductions of 10% to 20%. In 1 trial (n = 248), ezetimibe with simvastatin resulted in greater LDL-C reductions compared with simvastatin alone at 33 weeks (mean, -54.0% [SD, 1.4%] vs -38.1% [SD, 1.4%]). One trial of ezetimibe monotherapy (n = 138) showed mean LDL-C decreases of 28% (95% CI, -31% to -25%) from baseline and negligible change with placebo at 12 weeks. Eighteen studies found statins generally well tolerated. One observational study found lower, but still normal, dehydroepiandrosterone sulfate concentrations in statin-treated males with FH at 10-year follow-up. Bile acid-sequestering agents were commonly associated with adverse gastrointestinal symptoms and poor palatability. There was no eligible evidence on the effect of FH treatment on myocardial infarction or stroke in adulthood. CONCLUSIONS AND RELEVANCE: Screening can detect FH in children, and lipid-lowering treatment in childhood can reduce lipid concentrations in the short term, with little evidence of harm. There is no evidence for the effect of screening for FH in childhood on lipid concentrations or cardiovascular outcomes in adulthood, or on the long-term benefits or harms of beginning lipid-lowering treatment in childhood.

RESUMEN

PURPOSE: Family history of colorectal cancer (CRC) is a known risk factor for CRC and encompasses both genetic and shared environmental risks. METHODS: We conducted a systematic review to estimate the impact of family history on the natural history of CRC and adherence to screening. RESULTS: We found high heterogeneity in family-history definitions, the most common definition being one or more first-degree relatives. The prevalence of family history may be lower than the commonly cited 10%, and confirms evidence for increasing levels of risk associated with increasing family-history burden. There is evidence for higher prevalence of adenomas and of multiple adenomas in people with family history of CRC but no evidence for differential adenoma location or adenoma progression by family history. Limited data regarding the natural history of CRC by family history suggest a differential age or stage at cancer diagnosis and mixed evidence with respect to tumor location. Adherence to recommended colonoscopy screening was higher in people with a family history of CRC. CONCLUSION: Stratification based on polygenic and/or multifactorial risk assessment may mature to the point of displacing family history-based approaches, but for the foreseeable future, family history may remain a valuable clinical tool for identifying individuals at increased risk for CRC.

RESUMEN

Human papillomavirus (HPV) vaccination rates are significantly lower than recommended targets. Public awareness campaigns can raise awareness of the severity and prevalence of HPV infection and the cancer prevention benefits of the vaccine. We conducted an environmental scan of HPV vaccine public awareness campaigns during the summer of 2014. We used online search strategies and expert input to identify candidate campaigns. Multiple study investigators reviewed all data abstraction and analysis. After applying our inclusion criteria, we identified 14 campaigns with parents or teenagers as the target audience. We characterized campaign messages according to constructs of the Health Belief Model. Most messages focused on the cancer prevention benefits of HPV vaccine; few addressed psychological or practical barriers to getting or completing the vaccine. Four of 14 campaigns had pre- or postcampaign data readily available, only 2 used vaccine outcomes in their evaluations. We concluded there was a high prevalence of HPV vaccine public awareness campaigns but little available evidence on their impact on intermediate or vaccine outcomes.

RESUMEN

PURPOSE: Patient out-of-pocket costs are higher for cancer care than for any other health-care sector. Oncologist-patient discussions of costs are not well understood. We conducted an exploratory interview study to examine the frequency, patterns, attitudes, and preferences of both patients and providers on discussion of treatment costs. METHODS: We conducted semi-structured telephone interviews with oncology clinicians and people receiving chemotherapy at a large nonprofit health system. Multiple investigators conducted thematic analysis using modified content analysis, grounded theory, and interaction analysis methods. RESULTS: Patient themes included the relevance of cost to their experience, preference for the doctor to be the starting point of cost discussions, but relative infrequency of discussions with doctors or other care team member. Provider themes were an emphasis on clinical benefit above costs, conviction that cost-related decisions should rest with patients, and lack of access to treatment costs. Interest in discussing costs and barriers accessing cost information were common themes from both patients and providers. CONCLUSIONS: Doctors and patients want to discuss treatment costs but lack access to them. These data support growing evidence for a provider role in discussions of cost during cancer treatment planning.
