Outcomes and provider perspectives on geriatric care by a nurse practitioner-led community paramedicine program.

This study explores the use of a nurse practitioner-led paramedicine program for acute, home-based care of geriatric patients. This case series describes patients, outcomes, and geriatric primary care provider perspectives related to use of this independent paramedicine program. There were 40 patient visits from August 2016-May 2017. We reviewed patient demographics, medical conditions, healthcare utilization, and communication processes and used semi-structured interviews and content analysis to explore staff perspectives. The most commonly treated diagnoses were respiratory conditions, urinary tract infections, and gastrointestinal concerns. Two patients required an immediate transfer to a higher level of care. Six patients had emergency department visits and five patients were hospitalized within two weeks. Geriatric providers identified three themes including: potential benefits to geriatric patients, importance of enhanced care coordination and communication, and considerations for the specific role of nurse practitioner-led community paramedicine programs for geriatric patient care.

Sociopsychological tailoring to address colorectal cancer screening disparities: a randomized controlled trial.

PURPOSE: Interventions tailored to sociopsychological factors associated with health behaviors have promise for reducing colorectal cancer screening disparities, but limited research has assessed their impact in multiethnic populations. We examined whether an interactive multimedia computer program (IMCP) tailored to expanded health belief model sociopsychological factors could promote colorectal cancer screening in a multiethnic sample. METHODS: We undertook a randomized controlled trial, comparing an IMCP tailored to colorectal cancer screening self-efficacy, knowledge, barriers, readiness, test preference, and experiences with a nontailored informational program, both delivered before office visits. The primary outcome was record-documented colorectal cancer screening during a 12-month follow-up period. Secondary outcomes included postvisit sociopsychological factor status and discussion, as well as clinician recommendation of screening during office visits. We enrolled 1,164 patients stratified by ethnicity and language (49.3% non-Hispanic, 27.2% Hispanic/English, 23.4% Hispanic/Spanish) from 26 offices around 5 centers (Sacramento, California; Rochester and the Bronx, New York; Denver, Colorado; and San Antonio, Texas). RESULTS: Adjusting for ethnicity/language, study center, and the previsit value of the dependent variable, compared with control patients, the IMCP led to significantly greater colorectal cancer screening knowledge, self-efficacy, readiness, test preference specificity, discussion, and recommendation. During the followup period, 132 (23%) IMCP and 123 (22%) control patients received screening (adjusted difference = 0.5 percentage points, 95% CI -4.3 to 5.3). IMCP effects did not differ significantly by ethnicity/language. CONCLUSIONS: Sociopsychological factor tailoring was no more effective than nontailored information in encouraging colorectal cancer screening in a multiethnic sample, despite enhancing sociopsychological factors and visit behaviors associated with screening. The utility of sociopsychological tailoring in addressing screening disparities remains uncertain.

Multidisciplinary Approach to Deprescribing Sedative-Hypnotic Medications in Geriatric Primary Care.

INTRODUCTION/OBJECTIVES: Due to the risks associated with sedative hypnotic medications in older adults, our study evaluated the impact of a multidisciplinary approach to deprescribing in geriatric primary care clinics. METHODS: The study was a retrospective review of older adults at 2 academic, geriatric primary care clinics who were prescribed sedative-hypnotic medications. Patients were mailed an education packet of information that included working with the clinical pharmacy team, behavioral health team, or both in order to deprescribe their sedative-hypnotic medication. The study assessed the rate of discontinuation of sedative-hypnotic medications between the different intervention groups. RESULTS: The study included 93 older adults with a mean age of 81.3 years and 39.8% discontinuation rate of their medication. The number of falls decreased in patients who discontinued use compared to when previously using a sedative hypnotic medication. CONCLUSION: Patients are more likely to discontinue their sedative hypnotic medication with a multidisciplinary approach, specifically with primary care provider support.

Card studies for observational research in practice.

PURPOSE: Observational studies that collect patient-level survey data at the point-of-care are often called card studies. Card studies have been used to describe clinical problems, management, and outcomes in primary care for more than 30 years. In this article we describe 2 types of card studies and the methods for conducting them. METHODS: We undertook a descriptive review of card studies conducted in 3 Colorado practice-based research networks and several other networks throughout the United States. We summarized experiences of the State Networks of Colorado Ambulatory Practices and Partners (SNOCAP). RESULTS: Card studies can be designed to study specific conditions or care (clinicians complete a card when they encounter patients who meet inclusion criteria) and to determine trends and prevalence of conditions (clinicians complete a card on all patients seen during a period). Data can be collected from clinicians and patients and can be linked. CONCLUSIONS: Card studies provide cross-sectional descriptive data about clinical care, knowledge and behavior, perception of care, and prevalence of conditions. Card studies remain a robust method for describing primary care.

Pharmacist-Led Transition of Care Pilot Targeting Older People After Emergency Department Discharge.

OBJECTIVE: To evaluate the impact of a pharmacist-led transitional care intervention targeting high-risk older people after an emergency department (ED) visit.
DESIGN: Retrospective cohort study of older people with ED visits prior to and during a pharmacist-led intervention.
SETTING: Patients receiving primary care from the University of Colorado Health Seniors Clinic.
PARTICIPANTS: The intervention cohort comprised 170 patients with an ED visit between August 18, 2018, and February 19, 2019, and the historical cohort included 166 patients with an ED visit between August 18, 2017, and February 19, 2018. All included patients either had a historical diagnosis of heart failure or chronic obstructive pulmonary disease, or they had an additional ED visit in the previous six months.
INTERVENTIONS: The pilot intervention involved postED discharge telephonic outreach and assessment by a clinical pharmacist, with triaging to other staff if necessary.
MAIN OUTCOME MEASURE: The primary outcome was the proportion of patients with at least one repeat ED visit, hospitalization, or death within 30 days of ED discharge. Outcome rates were also assessed at 90 days postdischarge.
RESULTS: The primary outcome occurred in 21% of the historical cohort and 25% of the intervention cohort (adjusted P-value = 0.48). The incidence of the composite outcome within 90 days of ED discharge was 43% in the historical group compared with 38% in the intervention group (adjusted P-value = 0.29).
CONCLUSION: A pharmacist-led telephonic intervention pilot targeting older people did not appear to have a significant effect on the composite of repeat ED visit, hospitalization, or death within 30 or 90 days of ED discharge. A limited sample size may hinder the ability to make definitive conclusions based on these findings.

Disparities in Video and Telephone Visits Among Older Adults During the COVID-19 Pandemic: Cross-Sectional Analysis.

BACKGROUND: Telephone and video telemedicine appointments have been a crucial service delivery method during the COVID-19 pandemic for maintaining access to health care without increasing the risk of exposure. Although studies conducted prior to the pandemic have suggested that telemedicine is an acceptable format for older adults, there is a paucity of data on the practical implementation of telemedicine visits. Due to prior lack of reimbursement for telemedicine visits involving nonrural patients, no studies have compared telephone visits to video visits in geriatric primary care. OBJECTIVE: This study aimed to determine (1) whether video visits had longer durations, more visit diagnoses, and more advance care planning discussions than telephone visits during the rapid implementation of telemedicine in the COVID-19 pandemic, and (2) whether disparities in visit type existed based on patient characteristics. METHODS: We conducted a retrospective, cross-sectional analysis of patients seen at two geriatric clinics from April 23 to May 22, 2020. Approximately 25% of patients who had telephone and video appointments during this time underwent chart review. We analyzed patient characteristics, visit characteristics, duration of visits, number of visit diagnoses, and the presence of advance care planning discussion in clinical documentation. RESULTS: Of the 190 appointments reviewed, 47.4% (n=90) were video visits. Compared to telephone appointments, videoconferencing was, on average, 7 minutes longer (mean 37.3 minutes, SD 10 minutes; P<.001) and had, on average, 1.2 more visit diagnoses (mean 5.7, SD 3; P=.001). Video and telephone visits had similar rates of advance care planning. Furthermore, hearing, vision, and cognitive impairment did not result in different rates of video or telephone appointments. Non-White patients, patients who needed interpreter services, and patients who received Medicaid were less likely to have video visits than White patients, patients who did not need an interpreter, and patients who did not receive Medicaid, respectively (P=.003, P=.01, P<.001, respectively). CONCLUSIONS: Although clinicians spent more time on video visits than telephone visits, more than half of this study's older patients did not use video visits, especially if they were from racial or ethnic minority backgrounds or Medicaid beneficiaries. This potential health care disparity merits greater attention.

Lack of impact of direct-to-consumer advertising on the physician-patient encounter in primary care: a SNOCAP report.

PURPOSE: Direct-to-consumer advertising (DTCA) has increased tremendously during the past decade. Recent changes in the DTCA environment may have affected its impact on clinical encounters. Our objective was to determine the rate of patient medication inquiries and their influence on clinical encounters in primary care. METHODS: Our methods consisted of a cross-sectional survey in the State Networks of Colorado Ambulatory Practices and Partners, a collaboration of 3 practice-based research networks. Clinicians completed a short patient encounter form after consecutive patient encounter for one-half or 1 full day. The main outcomes were the rate of inquiries, independent predictors of inquiries, and overall impact on clinical encounters. RESULTS: One hundred sixty-eight clinicians in 22 practices completed forms after 1,647 patient encounters. In 58 encounters (3.5%), the patient inquired about a specific new prescription medication. Community health center patients made fewer inquiries than private practice patients (1.7% vs 7.2%, P<.001). Predictors of inquiries included taking 3 or more chronic medications and the clinician being female. Most clinicians reported the requested medication was not their first choice for treatment (62%), but it was prescribed in 53% of the cases. Physicians interpreted the overall impact on the visit as positive in 24% of visits, neutral in 66%, and negative in 10%. CONCLUSIONS: Patient requests for prescription medication were uncommon overall, and even more so among patients in lower income groups. These requests were rarely perceived by clinicians as having a negative impact on the encounter. Future mixed methods studies should explore specific socioeconomic groups and reasons for clinicians' willingness to prescribe these medications.

Use of an Ambulatory Patient Portal for Advance Care Planning Engagement.

BACKGROUND: Primary care clinics need sustainable, population-based approaches to engage patients in advance care planning (ACP). Patient portal-based ACP tools may provide an option for patient engagement. OBJECTIVE: To increase ACP outcomes by engaging older adults through portal-based ACP tools, including an electronic Medical Durable Power of Attorney (MDPOA) form. METHODS: Geriatric clinic pilot of a multi-modal population-based outreach strategy for portal-based ACP tools. Outreach was to patients (n = 105) who were 65 years and older with an active portal account, no cognitive impairment, and no MDPOA on file. Patients received a motivational message via the portal and, if not read within 2 weeks, a mailed postcard about the portal-based ACP tools. Primary outcome was composite of any ACP action at 1-year including 1) new advance directive (AD) in the electronic health record, 2) use of portal-based ACP tools, or 3) documented ACP discussion with a provider. RESULTS: Sixty-five older adults read the electronic message at 12 months. Seventeen (16%) engaged in at least 1 ACP action. Fourteen of 17 engaged by adding an AD to their record. More patients completed an AD on article or brought a previously completed AD to clinic, compared with choosing to complete an electronic MDPOA via the portal. CONCLUSIONS: Brief motivational messages about ACP via a patient portal is feasible and may increase ACP outcomes for older adults in primary care. Future studies should evaluate population-based portal outreach strategies in combination with team-based workflows to enhance patient engagement in ACP.

Developing a Quality Measurement Strategy in an Academic Primary Care Setting: An Environmental Scan.

PURPOSE: The purpose of this project was to: (1) develop a strategy for primary care quality measurement using an environmental scan and interviews to identify best practices and candidate measures; (2) present recommendations to facilitate successful measurement. METHODS: Following stakeholder interviews and review of existing measures, we created a three-tiered recommendation system for selecting and implementing measures. We also developed a framework for reviewing and prioritizing measures and prepared a detailed project report. RESULTS: Interviews provided a broader perspective on measuring quality, including implementing measures, measuring value, and identifying measurement gaps. Our recommendations fall into three tiers: Tier 1 measures can be implemented quickly and include clinical processes and outcomes for preventive care and disease states. Tier 2 measures require modifications to electronic health record, workflows, and/or staff preparation. Tier 3 (Strategic Vision) addresses topics that should be incorporated in the future to ensure high-quality primary care (adherence, patient activation, patient experience, teamness, staff satisfaction, and value), and infrastructure development to support ongoing quality measurement. CONCLUSIONS: Implementing a quality measurement strategy is challenging and labor-intensive but is necessary to improve healthcare quality. Our work demonstrates the effort and investment required to progress quality measurement and offers recommendations for successfully undertaking this type of endeavor.

Development and economic evaluation of a pharmacist-provided chronic care management service in an ambulatory care geriatrics clinic.

PURPOSE: The implementation and delivery of a pharmacist-led chronic care management (CCM) service in a geriatric primary care clinic are described. METHODS: A CCM service was provided March 1 through December 31, 2016, at the University of Colorado Hospital Seniors Clinic ("Seniors Clinic"). The electronic health record (EHR) team for the University of Colorado Health system developed a patient registry through EPIC Healthy Planet (Epic Systems Corp., Verona, WI) to identify patients at the Seniors Clinic eligible for CCM services. The EHR team constructed a note type and documentation template within the EHR to ensure documentation of all necessary components for billing and to allow individual clinical staff to document the time spent providing CCM care. RESULTS: Overall, 36 elderly patients enrolled in the pharmacist-provided CCM service over the 10 months. Clinical pharmacists spent a total of 156-849 minutes per month providing CCM services, with a mean outreach time of 45.4 minutes per patient. The clinical pharmacists submitted 95 claims, and all but 5 were paid. The total amount reimbursed from the health plans during the 10 months was $2,775.02. CONCLUSION: Medicare patients were successfully enrolled in a CCM service in a geriatrics primary care clinic led by clinical pharmacists and medical providers. The CCM services were more time-consuming than the allotted 20 minutes per patient per month with the CCM Current Procedural Terminology code used during this study.

Characteristics and Patterns of Marijuana Use in Community-Dwelling Older Adults.

OBJECTIVES: To understand patterns of marijuana use in community-dwelling older adults in Colorado. DESIGN: Anonymous survey. SETTING: Two academic geriatric primary care clinics. PARTICIPANTS: English-speaking individuals. MEASUREMENTS: We assessed self-reported characteristics and patterns of marijuana use and effect on targeted symptoms. Survey analysis focused on current users, defined as individuals who had used marijuana in the past 3 years. RESULTS: Three hundred forty-five individuals completed the survey (55% response rate); 113 (32%) had used marijuana in the past, of whom 55 (16%) had used since legalization. More than half of current users were aged 75 and older, and one-quarter were aged 85 and older. Most current users were white women. Of current users, 44% used marijuana products at least weekly for common conditions including chronic pain, depression, anxiety, and insomnia, and most found marijuana helpful for these conditions. Most respondents reported obtaining marijuana recreationally (67%) without a prescription. Nine respondents reported negative side effects attributable to marijuana use. CONCLUSION: To our knowledge, this is the first study to characterize marijuana use of older adults in a state in which it is legal for medical and recreational use. Marijuana was used for several common geriatric conditions, and respondents reported few side effects. The small number of survey respondents, the lack of generalizability in states where marijuana sales are illegal, and participation bias were the main study limitations. Further research is needed to better understand useful or harmful effects in this population. J Am Geriatr Soc 66:2167-2171, 2018.

Action or inaction? Decision making in patients with diabetes and elevated blood pressure in primary care.

OBJECTIVE: Hypertension increases micro- and macrovascular complications of diabetes. The goal for blood pressure is <130/80 mmHg. In primary care, however, blood pressure in many patients exceeds this goal. In this study, we evaluated the clinical decision-making process when a patient with diabetes presents with elevated blood pressure. RESEARCH DESIGN AND METHODS: Twenty-six primary care practices in two practice-based research networks in Colorado participated. Questionnaires were completed after each encounter with an adult with type 2 diabetes. Data obtained from the survey included 1) demographic information, 2) blood pressure results, 3) action taken, 4) type of action if action was taken, and 5) reasons for inaction if action was not taken. Bivariate and multivariate analyses were performed to identify predictors of action. RESULTS: Completed surveys totaled 778. Blood pressure was 130/74 +/- 18.8/12.0 mmHg (mean +/- SD). Sixty-two percent of patients exceeded goals. Action was taken to lower blood pressure in 34.9% of those. Predictors of action were 1) blood pressure level, 2) total number of medicines the patient was taking, and 3) patient already taking medicines for blood pressure. As blood pressure rose, providers attributed inaction more often to "competing demands" and reasons other than "blood pressure being at or near goal." CONCLUSIONS: No evidence was found for patterns of poor care among primary care physicians. Providers balance the clinical circumstances, including how elevated the blood pressure is, and issues of polypharmacy, medication side effects, and costs when determining the best course of action. Knowledge deficit is not a common cause of inaction.

Missing clinical information during primary care visits.

CONTEXT: The coordinating function of primary care is information-intensive and may be impeded by missing clinical information. However, missing clinical information has not been explicitly investigated in the primary care setting. OBJECTIVE: To describe primary care clinicians' reports of missing clinical information. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional survey conducted in 32 primary care clinics within State Networks of Colorado Ambulatory Practices and Partners (SNOCAP), a consortium of practice-based research networks participating in the Applied Strategies for Improving Patient Safety medical error reporting study. Two hundred fifty-three clinicians were surveyed about 1614 patient visits between May and December 2003. For every visit during 1 half-day session, each clinician completed a questionnaire about patient and visit characteristics and stated whether important clinical information had been missing. Clinician characteristics were also recorded. MAIN OUTCOME MEASURES: Reports of missing clinical information frequency, type, and presumed location; perceived likelihood of adverse effects, delays in care, and additional services; and time spent looking for missing information. Multivariate analysis was conducted to assess the relationship of missing information to patient, visit, or clinician characteristics, adjusting for potential confounders and effects of clustering. RESULTS: Clinicians reported missing clinical information in 13.6% of visits; missing information included laboratory results (6.1% of all visits), letters/dictation (5.4%), radiology results (3.8%), history and physical examination (3.7%), and medications (3.2%). Missing clinical information was frequently reported to be located outside their clinical system but within the United States (52.3%), to be at least somewhat likely to adversely affect patients (44%), and to potentially result in delayed care or additional services (59.5%). Significant time was reportedly spent unsuccessfully searching for missing clinical information (5-10 minutes, 25.6%; >10 minutes, 10.4%). After adjustment, reported missing clinical information was more likely when patients were recent immigrants (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.06-2.99), new patients (OR, 2.39; 95% CI, 1.70-3.35), or had multiple medical problems compared with no problems (1 problem: OR, 1.09; 95% CI, 0.69-1.73; 2-5 problems: OR, 1.87; 95% CI, 1.21-2.89; >5 problems: OR, 2.78; 95% CI, 1.61-4.80). Missing clinical information was less likely in rural practices (OR, 0.52; 95% CI, 0.29-0.92) and when individual clinicians reported having full electronic records (OR, 0.40; 95% CI, 0.17-0.94). CONCLUSIONS: Primary care clinicians report that missing clinical information is common, multifaceted, likely to consume time and other resources, and may adversely affect patients. Additional research on missing information is needed to focus on validating clinicians' perceptions and on conducting prospective studies of its causes and sequelae.

Clinical decisions regarding HbA1c results in primary care: a report from CaReNet and HPRN.

OBJECTIVE: To describe decisions made by primary care providers on elevated HbA(1c) results and their reasons for not intensifying therapy. RESEARCH DESIGN AND METHODS: In this cross-sectional study, a provider survey was administered in two practice-based research networks when HbA(1c) results were reviewed on all nonpregnant patients >18 years old with type 2 diabetes. Univariate and Mantel-Hantel analyses assessed associations between patient characteristics and clinical decisions. RESULTS: A total of 483 surveys were completed by at least 88 providers at 19 clinics. Most patients were female (62.5%), mean age was 60 years, and 28.6% were Hispanic. The overall action rate on HbA(1c) results >/=7% (n = 294) was 70.7%. Patients who were black or had Medicare without medication insurance had lower rates of action on HbA(1c) >/=7 and >/=8%, respectively (P < 0.05). The most common reasons providers reported for inaction were "patient improving/doing well," "competing demands," and "hypoglycemic risk." CONCLUSIONS: Primary care providers generally adhere to national glycemic control guidelines, although there may be disparities in black patients and patients without medication insurance coverage. A variety of reasons were given when control was not intensified.

Success in the Achieving CARdiovascular Excellence in Colorado (A CARE) Home Blood Pressure Monitoring Program: A Report from the Shared Networks of Colorado Ambulatory Practices and Partners (SNOCAP).

BACKGROUND: Blood pressure (BP) control among primary care patients with hypertension is suboptimal. Home BP monitoring (HBPM) has been shown to be effective but is underused. METHODS: This study was a quasi-experimental evaluation of the impact of the A CARE HBPM program on hypertension control. Nonpregnant adults with hypertension or cardiovascular disease risk factors were given validated home BP monitors and reported monthly average home BP readings by Internet or phone. Patients and providers received feedback. Change in average home and office BP and the percentage of patients achieving target BP were assessed based on patient HBPM reports and a chart audit of office BPs. RESULTS: A total of 3578 patients were enrolled at 26 urban and rural primary care practices. Of these, 36% of participants submitted ≥2 HBPM reports. These active participants submitted a mean of 13.5 average HBPM reports, with a mean of 19.3 BP readings per report. The mean difference in home BP between initial and final HBPM reports for active participants was -6.5/-4.4 mmHg (P < .001) and -6.7/-4.7 mmHg (P < .001) for those with diabetes. The percentage of active participants at or below target BP increased from 34.5% to 53.3% (P < .001) and increased 24.6% to 40.0% (P < .001) for those with diabetes. The mean difference in office BP over 1 year between participants and nonparticipants was -5.4/-2.7 mmHg (P < .001 for systolic BP, P = .01 for diastolic BP) for all participants and -8.5/-1.5 mmHg (P = .014 for systolic BP, P = .405 for diastolic BP) for those with diabetes. CONCLUSIONS: An HBPM program with patient and provider feedback can be successfully implemented in a range of primary care practices and can play a significant role in BP control and decreased cardiovascular disease risk in patients with hypertension.

Effects of pioglitazone or exercise in older adults with mild cognitive impairment and insulin resistance: a pilot study.

AIMS: To examine the effects of pioglitazone or endurance exercise training on cognitive function in older adults with mild cognitive impairment (MCI) and insulin resistance. METHODS: Seventy-eight adults (mean age ± SD: 65 ± 7 years) with central obesity and MCI were randomized to 6 months of endurance exercise, pioglitazone or control. RESULTS: Sixty-six participants completed the study. Exercise training did not significantly increase peak oxygen uptake compared to control (p = 0.12). Compared to control, insulin resistance improved in the pioglitazone group (p = 0.002) but not in the exercise group (p = 0.25). There was no measureable effect of pioglitazone or exercise on cognitive performance compared to control. CONCLUSION: In this pilot study, pioglitazone improved insulin resistance but not cognitive performance in older adults with MCI and insulin resistance.

Medications for the Treatment of Sleep Disorders: An Overview.

Sleep disorders can be divided into those producing insomnia, those causing daytime sleepiness, and those disrupting sleep. Transient insomnia is extremely common, afflicting up to 80% of the population. Chronic insomnia affects 15% of the population. Benzodiazepines are frequently used to treat insomnia; however, there may be a withdrawal syndrome with rapid eye movement (REM) rebound. Two newer benzodiazepine-like agents, zolpidem and zaleplon, have fewer side effects, yet good efficacy. Other agents for insomnia include sedating antidepressants and over-the-counter sleep products (sedating antihistamines). Nonpharmacologic behavioral methods may also have therapeutic benefit. An understanding of the electrophysiologic and neurochemical correlates of the stages of sleep is useful in defining and understanding sleep disorders. Excessive daytime sleepiness is often associated with obstructive sleep apnea or depression. Medications, including amphetamines, may be used to induce daytime alertness. Parasomnias include disorders of arousal and of REM sleep. Chronic medical illnesses can become symptomatic during specific sleep stages. Many medications affect sleep stages and can thus cause sleep disorders or exacerbate the effect of chronic illnesses on sleep. Conversely, medications may be used therapeutically for specific sleep disorders. For example, restless legs syndrome and periodic limb movement disorder may be treated with dopamine agonists. An understanding of the disorders of sleep and the effects of medications is required for the appropriate use of medications affecting sleep.

Tobacco cessation counseling among underserved patients: a report from CaReNet.

OBJECTIVES: The purpose of our study was to determine the frequency of smoking cessation counseling in relation to insurance status in a practice-based research network. STUDY DESIGN: We administered a modified National Ambulatory Medical Care Survey (NAMCS), with an additional payment category to identify uninsured patients, quarterly to 100 random patients at each practice site for 1 year. POPULATION: The study population included the patients at the 7 practices within the Colorado Research Network (CaReNet), associated with the Department of Family Medicine, University of Colorado Health Science Center. OUTCOMES MEASURED: We measured the prevalence of smoking and the frequency of cessation counseling. RESULTS: Of 2773 visits analyzed, 1443 were made by adults who were either was uninsured (39%), had Medicaid (22%), or had private or a health maintenance organization insurance (private/HMO; 40%). Smoking prevalence was significantly greater in uninsured patients (30%) and Medicaid patients (31%), compared with private/HMO patients (22%) (P =.008). However, those smokers with private/HMO insurance were more likely to receive tobacco counseling (50%) than Medicaid (41%) and uninsured (25%) patients (P <.001). After controlling for potential confounders, this difference remained significant. CONCLUSIONS: Although smoking is more common among Medicaid and uninsured patients, these smokers are less likely to receive counseling. Possible explanations for this disparity include lack of access to cessation interventions or lower quality of care for underserved patients. This finding may have implications for achieving national public health goals on smoking cessation.

Effects of tailored knowledge enhancement on colorectal cancer screening preference across ethnic and language groups.

OBJECTIVE: Tailoring to psychological constructs (e.g. self-efficacy, readiness) motivates behavior change, but whether knowledge tailoring alone changes healthcare preferences--a precursor of behavior change in some studies--is unknown. We examined this issue in secondary analyses from a randomized controlled trial of a tailored colorectal cancer (CRC) screening intervention, stratified by ethnicity/language subgroups (Hispanic/Spanish, Hispanic/English, non-Hispanic/English). METHODS: Logistic regressions compared effects of a CRC screening knowledge-tailored intervention versus a non-tailored control on preferences for specific test options (fecal occult blood or colonoscopy), in the entire sample (N=1164) and the three ethnicity/language subgroups. RESULTS: Pre-intervention, preferences for specific tests did not differ significantly between study groups (experimental, 64.5%; control 62.6%). Post-intervention, more experimental participants (78.6%) than control participants (67.7%) preferred specific tests (P<0.001). Adjusting for pre-intervention preferences, more experimental group participants than control group participants preferred specific tests post-intervention [average marginal effect (AME)=9.5%, 95% CI 5.3-13.6; P<0.001]. AMEs were similar across ethnicity/language subgroups. CONCLUSION: Knowledge tailoring increased preferences for specific CRC screening tests across ethnic and language groups. PRACTICE IMPLICATIONS: If the observed preference changes are found to translate into behavior changes, then knowledge tailoring alone may enhance healthy behaviors.

An assessment of the Hawthorne Effect in practice-based research.

BACKGROUND: Practical studies in real-world settings may be particularly vulnerable to unintended effects on intervention outcomes, including what is commonly known as the Hawthorne Effect. This phenomenon suggests that study subjects' behavior or study results are altered by the subjects' awareness that they are being studied or that they received additional attention. This is especially a concern when subjects are not blinded to randomization or when they participate in studies with observational components. As part of a larger practical intervention designed to improve the clinical management of skin and soft tissue infections (SSTIs), we specifically examined the potential for a Hawthorne Effect from the extra attention some clinicians received when completing follow-up case reviews. METHODS: De-identified, electronic data from a larger practical intervention allowed for the comparison of the clinical management of SSTIs among 14 randomly selected clinicians who participated in follow-up case reviews versus 77 clinicians who did not. RESULTS: There were no differences in the management of SSTIs between the 2 groups of clinicians. No evidence of a Hawthorne Effect was observed in this quality-improvement intervention. CONCLUSION: More extensive contact with the research team did not seem to have unintended effects on the outcomes of interest for the management of SSTIs. Further study in practice-based research settings could help to establish whether different types of studies and outcomes are more or less susceptible to the Hawthorne Effect.
