RESUMO
BACKGROUND: Although colorectal cancer (CRC) prognosis is improved by early diagnosis, screening rates remain low. OBJECTIVE: To determine the effect of an automated telephone intervention on completion of fecal occult blood testing (FOBT). RESEARCH DESIGN: In this randomized controlled trial conducted at Kaiser Permanente Northwest, a not-for-profit health maintenance organization, 5905 eligible patients aged 51 to 80, at average risk for CRC and due for CRC screening, were randomly assigned to an automated telephone intervention (n = 2943) or usual care (UC; n = 2962). The intervention group received up to three 1-minute automated telephone calls that provided a description and health benefits of FOBT. During the call, patients could request that an FOBT kit be mailed to their home. Those who requested but did not return the cards received an automated reminder call. Cox proportional hazard method was used to determine the independent effect of automated telephone calls on completion of an FOBT, after adjusting for age, sex, and prior CRC screening. RESULTS: By 6 months after call initiation, 22.5% in the intervention and 16.0% in UC had completed an FOBT. Those in the intervention group were significantly more likely to complete an FOBT (hazard ratio, 1.31; 95% confidence interval, 1.10-1.56) compared with UC. Older patients (aged 71-80 vs. aged 51-60) were also more likely to complete FOBT (hazard ratio, 1.48; 95% confidence interval, 1.07-2.04). CONCLUSIONS: Automated telephone calls increased completion of FOBT. Further research is needed to evaluate automated telephone interventions among diverse populations and in other clinical settings.

OBJECTIVE: Despite known benefits of patient-perceived collaborative goal setting, we have a limited ability to monitor this process in practice. We developed the Patient Measure of Collaborative Goal Setting (PM-CGS) to evaluate the use of collaborative goal setting from the patient's perspective. RESEARCH DESIGN AND METHODS: A random sample of 400 patients aged 40â years or older, receiving diabetes care from the Virginia Commonwealth University Health System between 8/2012 and 8/2013, were mailed a survey containing potential PM-CGS items (n=44) as well as measures of patient demographics, perceived self-management competence, trust in their physician, and self-management behaviors. Confirmatory factor analysis was used to evaluate construct validity. External validity was evaluated via a structural equation model (SEM) that tested the association of the PM-CGS with self-management behaviors. The direct and two mediated (via trust and self-efficacy) pathways were tested. RESULTS: A total of 259 patients responded to the survey (64% response rate), of which 192 were eligible for inclusion. Results from the factor analysis supported a 37-item measure of patient-perceived CGS spanning five domains: listen and learn; share ideas; caring relationship; measurable objective; and goal achievement support (χ=4366.13, p<0.001; RMSEA=0.08). Results from the SEM supported the external validity of the PM-CGS. The relationship between CGS and self-management was partially mediated by perceived competence (p<0.05). The direct effect between the PM-CGS and self-management was significant (p<0.001). CONCLUSIONS: CGS can be validly measured by the 37-item PM-CGS. Use of the PM-CGS can help illustrate actionable deficits in goal-setting discussions.
RESUMO
OBJECTIVES: To estimate the cost-effectiveness of an automated telephone intervention for colorectal cancer screening from a managed care perspective, using data from a pragmatic randomized controlled trial. METHODS: Intervention patients received calls for fecal occult blood testing (FOBT) screening. We searched patients' electronic medical records for any screening (defined as FOBT, flexible sigmoidoscopy, double-contrast barium enema, or colonoscopy) during follow-up. Intervention costs included project implementation and management, telephone calls, patient identification, and tracking. Screening costs included FOBT (kits, mailing, and processing) and any completed screening tests during follow-up. We estimated the incremental cost-effectiveness ratio (ICER) of the cost per additional screen. RESULTS: At 6 months, average costs for intervention and control patients were $37 (25% screened) and $34 (19% screened), respectively. The ICER at 6 months was $42 per additional screen, less than half what other studies have reported. Cost-effectiveness probability was 0.49, 0.84, and 0.99 for willingness-to-pay thresholds of $40, $100, and $200, respectively. Similar results were seen at 9 months. A greater increase in FOBT testing was seen for patients aged >70 years (45/100 intervention, 33/100 control) compared with younger patients (25/100 intervention, 21/100 control). The intervention was dominant for patients aged >70 years and was $73 per additional screen for younger patients. It increased screening rates by about 6% and costs by $3 per patient. CONCLUSIONS: At willingness to pay of $100 or more per additional screening test, an automated telephone reminder intervention can be an optimal use of resources.

BACKGROUND: The relationship of a primary care provider's (PCP's) colorectal cancer (CRC) screening strategies to completion of screening is poorly understood. OBJECTIVE: To describe PCP test recommendation patterns and associated factors and their relationship to patient test completion. DESIGN: This cross-sectional study used a PCP survey, in-depth PCP interviews, and electronic medical records. SETTING: Kaiser Permanente Northwest health maintenance organization. PARTICIPANTS: Participants included 132 PCPs and 49,259 eligible patients aged 51 to 75. MEASUREMENTS: The authors grouped PCPs by patterns of CRC screening recommendations based on reported frequency of recommending fecal occult blood testing (FOBT), flexible sigmoidoscopy (FS), and colonoscopy. They then compared PCP demographics, reported CRC screening test influences, concerns, decision-making and counseling processes, and actual rates of patient CRC screening completion by PCP group. RESULTS: The authors identified 4 CRC screening recommendation groups: a "balanced" group (n = 54; 40.9%) that recommended the tests nearly equally, an FOBT group (n = 31; 23.5%) that largely recommended FOBT, an FOBT + FS group (n = 25; 18.9%), and a colonoscopy + FOBT group (n = 22; 16.7%) that recommended these tests nearly equally. Internal medicine (v. family medicine) PCPs were more common in groups more frequently recommending endoscopy. The FOBT and FOBT + FS groups were most influenced by clinical guidelines. Groups recommending more endoscopy were most concerned that FOBT generates a relatively high number of false positives and FOBT can miss cancers. The FOBT and FOBT + FS groups were more likely to recommend a specific screening strategy compared to the colonoscopy + FOBT and balanced groups, which were more likely to let the patient decide. CRC screening rates were 63.9% balanced, 62.9% FOBT, 61.7% FOBT + FS, and 62.2% colonoscopy + FOBT; rates did not differ significantly by group. LIMITATIONS: Small numbers within PCP groups. CONCLUSIONS: Specialty, the influence of guidelines, test concerns, and the "jointness" of the test selection decision distinguished CRC screening recommendation patterns. All patterns were associated with similar overall screening rates.

OBJECTIVE To estimate prevalence of, and factors associated with, sustained periods of hyperglycemia among patients with diabetes and factors associated with receipt of appropriate care once A1C values are persistently elevated. RESEARCH DESIGN AND METHODS Among patients initiating oral monotherapy (n = 5,070), Kaplan-Meier and Cox proportional hazards methods were used to estimate time to, and factors associated with, sustained hyperglycemia (defined by two A1cs >8% and no recent medication intensification), and among those experiencing sustained hyperglycemia, time to, and factors associated with, appropriate receipt of care (i.e., medication intensification or achieving A1C < or =7%). RESULTS Within 1 year, 8% experienced sustained hyperglycemia, with the proportion rising to 38% within 5 years. Patients using sulfonylurea had greater risk of hyperglycemia (hazard ratio [HR] 1.47 [95% CI 1.30-1.66]) compared with those initiating metformin. Risk increased with age (1.89 [1.27-2.83]), was greater for African Americans (1.19 [1.05-1.36]), and increased with A1C levels >7%. Among individuals with sustained hyperglycemia (n = 1,386), mean time to appropriate care was 9.7 months, with 25% not receiving appropriate care within 1 year. Shorter delays to appropriate care receipt were associated with increasing income (1.03 [1.00-1.07]), A1C >9% (1.38 [1.06-1.79]) and >11% (1.65 [1.25-2.18]), increasing medication adherence (1.03 [1.01-1.04]), and visits to primary care (4.22 [3.65-4.88]) or endocrinology (3.89 [2.26-6.70]). Longer delays were associated with increasing drug copayments (0.96 [0.93-0.98]). CONCLUSIONS Patients incurring sustained hyperglycemia are at risk of further delays in appropriate management. Barriers to appropriate care include prescription drug copayments, few physician contacts, and other factors that are likely amenable to intervention.

BACKGROUND: Previous studies have shown differences in adherence to inhaled corticosteroids (ICSs) by race-ethnicity, yet little is known about factors that contribute to adherence within these groups. Environmental stressors, such as crime exposure, which has been associated with asthma morbidity, might also predict ICS adherence. OBJECTIVE: We sought to identify factors associated with ICS adherence among patients with asthma and among African American patients and white patients separately. METHODS: Study patients with asthma were aged 18 to 50 years and were enrolled in a large southeast Michigan health maintenance organization between January 1, 1999, and December 31, 2001. The primary outcome, ICS adherence, was calculated by linking prescription-fill data with dosage information. Predictor variables included age, sex, race-ethnicity, measures of socioeconomic status (SES), average ICS copay, existing comorbidities, and crime rate in area of residence. RESULTS: Adherence information was available for 176 patients. ICS adherence was lower among African American patients (n = 75) when compared with white patients (n = 94; 40% vs 58%, respectively; P = .002). Among white patients, adherence was significantly lower for women when compared with men. Among African American patients, age and residential crime rates were positively and negatively associated with ICS adherence, respectively. Area crime remained a predictor of adherence in African American patients, even after adjusting for multiple measures of SES. CONCLUSIONS: This study suggests that an environmental stressor, area crime, provides additional predictive insight into ICS-adherent behavior beyond typical SES factors. CLINICAL IMPLICATIONS: Better understanding of environmental factors that influence ICS adherence might aid in efforts to improve it.
