Did you hear the one about the doctor? An examination of doctor jokes posted on Facebook.

BACKGROUND: Social networking sites such as Facebook have become immensely popular in recent years and present a unique opportunity for researchers to eavesdrop on the collective conversation of current societal issues. OBJECTIVE: We sought to explore doctor-related humor by examining doctor jokes posted on Facebook. METHODS: We performed a cross-sectional study of 33,326 monitored Facebook users, 263 (0.79%) of whom posted a joke that referenced doctors on their Facebook wall during a 6-month observation period (December 15, 2010 to June 16, 2011). We compared characteristics of so-called jokers to nonjokers and identified the characteristics of jokes that predicted joke success measured by having elicited at least one electronic laugh (eg, an LOL or "laughing out loud") as well as the total number of Facebook "likes" the joke received. RESULTS: Jokers told 156 unique doctor jokes and were the same age as nonjokers but had larger social networks (median Facebook friends 227 vs 132, P<.001) and were more likely to be divorced, separated, or widowed (P<.01). In 39.7% (62/156) of unique jokes, the joke was at the expense of doctors. Jokes at the expense of doctors compared to jokes not at the expense of doctors tended to be more successful in eliciting an electronic laugh (46.5% vs 37.3%), although the association was statistically insignificant. In our adjusted models, jokes that were based on current events received considerably more Facebook likes (rate ratio [RR] 2.36, 95% CI 0.97-5.74). CONCLUSIONS: This study provides insight into the use of social networking sites for research pertaining to health and medicine, including the world of doctor-related humor.

Effect of a Decision Aid on Agreement Between Patient Preferences and Repair Type for Abdominal Aortic Aneurysm: A Randomized Clinical Trial.

Importance: Patients with abdominal aortic aneurysm (AAA) can choose open repair or endovascular repair (EVAR). While EVAR is less invasive, it requires lifelong surveillance and more frequent aneurysm-related reinterventions than open repair. A decision aid may help patients receive their preferred type of AAA repair. Objective: To determine the effect of a decision aid on agreement between patient preference for AAA repair type and the repair type they receive. Design, Setting, and Participants: In this cluster randomized trial, 235 patients were randomized at 22 VA vascular surgery clinics. All patients had AAAs greater than 5.0 cm in diameter and were candidates for both open repair and EVAR. Data were collected from August 2017 to December 2020, and data were analyzed from December 2020 to June 2021. Interventions: Presurgical consultation using a decision aid vs usual care. Main Outcomes and Measures: The primary outcome was the proportion of patients who had agreement between their preference and their repair type, measured using χ2 analyses, κ statistics, and adjusted odds ratios. Results: Of 235 included patients, 234 (99.6%) were male, and the mean (SD) age was 73 (5.9) years. A total of 126 patients were enrolled in the decision aid group, and 109 were enrolled in the control group. Within 2 years after enrollment, 192 (81.7%) underwent repair. Patients were similar between the decision aid and control groups by age, sex, aneurysm size, iliac artery involvement, and Charlson Comorbidity Index score. Patients preferred EVAR over open repair in both groups (96 of 122 [79%] in the decision aid group; 81 of 106 [76%] in the control group; P = .60). Patients in the decision aid group were more likely to receive their preferred repair type than patients in the control group (95% agreement [93 of 98] vs 86% agreement [81 of 94]; P = .03), and κ statistics were higher in the decision aid group (κ = 0.78; 95% CI, 0.60-0.95) compared with the control group (κ = 0.53; 95% CI, 0.32-0.74). Adjusted models confirmed this association (odds ratio of agreement in the decision aid group relative to control group, 2.93; 95% CI, 1.10-7.70). Conclusions and Relevance: Patients exposed to a decision aid were more likely to receive their preferred AAA repair type, suggesting that decision aids can help better align patient preferences and treatments in major cardiovascular procedures.

Association of Regional Practice Environment Intensity and the Ability of Internists to Practice High-Value Care After Residency.

Importance: Use of health care services and physician practice patterns have been shown to vary widely across the United States. Although practice patterns-in particular, physicians' ability to provide high-quality, high-value care-develop during training, the association of a physician's regional practice environment with that ability is less well understood. Objective: To examine the association between health care intensity in the region where physicians practice and their ability to practice high-value care, specifically for physicians whose practice environment changed due to relocation after residency. Design, Setting, and Participants: This cohort study included a national sample of 3896 internal medicine physicians who took the 2002 American Board of Internal Medicine initial certification examination followed approximately 1 decade (April 21, 2011, to May 7, 2015) later by the Maintenance of Certification (MOC) examination. At the time of the MOC examination, 2714 of these internists were practicing in a new region. Data were analyzed from March 6, 2016, to May 21, 2018. Exposures: Intensity of care in the Dartmouth Atlas hospital referral region (HRR), measured by per-enrollee end-of-life physician visits (primary) and current practice type (secondary). Main Outcomes and Measures: The outcome, a physician's ability to practice high-value care, was assessed using the Appropriately Conservative Management (ACM) score on the MOC examination, measuring performance across all questions for which the correct answer was the most conservative option. The exposure, regional health care intensity, was measured as per-enrollee end-of-life physician visits in the Dartmouth Atlas HRR of the physician's practice. Results: Among the 3860 participating internists included in the analysis (2030 men [52.6%]; mean [SD] age, 45.6 [4.5] years), those who moved to regions in the quintile of highest health care intensity had an ACM score 0.22 SD lower (95% CI, -0.32 to -0.12) than internists who moved to regions in the quintile of lowest intensity, controlling for postresidency ACM scores. This difference reflected scoring in the 44th compared with the 53rd percentile of all examinees. This association was mildly attenuated (0.18 SD less; 95% CI, -0.28 to -0.09) after adjustment for physician and practice characteristics. Conclusions and Relevance: This study found that practice patterns of internists who relocate after residency training appear to migrate toward norms of the new region. The demands of practicing in high-intensity regions may erode the ability to practice high-value conservative care.

Discharge-ready volume status in acute decompensated heart failure: a survey of hospitalists.

Acute decompensated heart failure is the leading cause of hospitalization in older adults. Clinical practice guidelines recommend patients should be euvolemic at hospital discharge - yet accurate assessment of volume status is recognized to be exceptionally challenging. This conundrum led us to investigate how hospitalists are assessing volume status and discharge- readiness of patients hospitalized with heart failure. We collected audience response data during a didactic heart failure presentation at the 2019 Society of Hospital Medicine annual meeting. Respondents (n = 216), 76% of whom were practicing physician hospitalists caring for more than 20 acute heart failure patients per year, were presented six questions. Eighteen percent of respondents reported not being able to determine the completeness of decongestion on discharge and 32% reported that complete decongestion was not a treatment target. These findings suggest important differences between guideline recommendations and how hospitalists treat heart failure in current clinical practice.

Current antibiotic therapy for isolated urinary tract infections in women.

BACKGROUND: Sulfa antibiotics, such as a combination product of trimethoprim and sulfamethoxazole, have traditionally been the drugs of choice for urinary tract infections (UTIs) and remained the most common treatment as recently as a decade ago. However, increasing sulfa resistance among Escherichia coli may have led to changes in prescribing practices. METHODS: We used the 2000-2002 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey to obtain nationally representative data on antibiotics prescribed for women with isolated outpatient UTIs following visits to physicians' offices, hospital clinics, and emergency departments (n = 2638). Logistic regression was used to determine predictors of quinolone use. RESULTS: Quinolones were more commonly prescribed than sulfa antibiotics in each year evaluated. In the most recent year of data, quinolones were prescribed in 48% and sulfas in 33% of UTI visits (P<.04). Quinolones were significantly more likely to be prescribed to older patients and in visits occurring in the Northeast; however, no difference in quinolone prescribing was seen when evaluating insurance status, setting, race, ethnicity, health care provider type, and year. Approximately one third of the quinolones used were broader-spectrum agents. CONCLUSIONS: Quinolones have surpassed sulfas as the most common class of antibiotic prescribed for isolated outpatient UTI in women. Few significant predictors of quinolone use exist, suggesting that the increase is not confined to a certain subset of patients. This pervasive growth in quinolone use raises concerns about increases in resistance to this important class of antibiotics.

Regional variations in health care intensity and physician perceptions of quality of care.

BACKGROUND: Research has documented dramatic differences in health care utilization and spending across U.S. regions with similar levels of patient illness. Although patient outcomes and quality of care have been found to be no better in regions of high health care intensity, it is unknown whether physicians in these regions feel more capable of providing good patient care than those in low-intensity regions. OBJECTIVE: To determine whether physicians in high-intensity regions feel better able to care for patients than physicians in low-intensity regions. DESIGN: Physician telephone survey. SETTING: 51 metropolitan and 9 nonmetropolitan areas of the United States and a supplemental national sample. PARTICIPANTS: 10,577 physicians who provided care to adults in 1998 or 1999 were surveyed for the Community Tracking Study (response rate, 61%). MEASUREMENTS: The End-of-Life Expenditure Index, a measure of spending that reflects differences in the overall quantity of medical services provided rather than differences in illness or price, was used to determine health care intensity in the physicians' community. Outcomes included physicians' perceived availability of clinical services, ability to provide high-quality care to patients, and career satisfaction. RESULTS: Although the highest-intensity regions have substantially more hospital beds and specialists per capita, physicians in these regions reported more difficulty obtaining needed services for their patients. The proportion of physicians who felt able to obtain elective hospital admissions ranged from 50% in high-intensity regions to 64% in the lowest-intensity region (P < 0.001 for the relationship between intensity and perceived ability to obtain hospital admissions); the proportion of physicians who felt able to obtain high-quality specialist referrals ranged from 64% in high-intensity regions to 79% in low-intensity regions (P < 0.001). Compared with low-intensity regions, fewer physicians in high-intensity regions felt able to maintain good ongoing patient relationships (range, 62% to 70%; P < 0.001) or able to provide high-quality care (range, 72% to 77%; P = 0.009). In most cases, differences persisted but were attenuated in magnitude after adjustment for physician attributes, practice characteristics, and local market factors (for example, managed care penetration); the difference in perceived ability to provide high-quality care was no longer statistically significant (P = 0.099). LIMITATIONS: The cross-sectional design prevented demonstration of a causal relationship between intensity and physician perceptions of quality. CONCLUSION: Despite more resources, physicians in regions of high health care intensity did not report greater ease in obtaining needed services or greater ability to provide high-quality care.

The Burden of Cystoscopic Bladder Cancer Surveillance: Anxiety, Discomfort, and Patient Preferences for Decision Making.

OBJECTIVE: To examine discomfort, anxiety, and preferences for decision making in patients undergoing surveillance cystoscopy for non-muscle-invasive bladder cancer (NMIBC). METHODS: Veterans with a prior diagnosis of NMIBC completed validated survey instruments assessing procedural discomfort, worry, and satisfaction, and were invited to participate in semistructured focus groups about their experience and desire to be involved in surveillance decision making. Focus group transcripts were analyzed qualitatively, using (1) systematic iterative coding, (2) triangulation involving multiple perspectives from urologists and an implementation scientist, and (3) searching and accounting for disconfirming evidence. RESULTS: Twelve patients participated in 3 focus groups. Median number of lifetime cystoscopy procedures was 6.5 (interquartile range 4-10). Based on survey responses, two-thirds of participants (64%) experienced some degree of procedural discomfort or worry, and all participants reported improvement in at least 2 dimensions of overall well-being following cystoscopy. Qualitative analysis of the focus groups indicated that participants experience preprocedural anxiety and worry about their disease. Although many participants did not perceive themselves as having a defined role in decision making surrounding their surveillance care, their preferences to be involved in decision making varied widely, ranging from acceptance of the physician's recommendation, to uncertainty, to dissatisfaction with not being involved more in determining the intensity of surveillance care. CONCLUSION: Many patients with NMIBC experience discomfort, anxiety, and worry related to disease progression and not only cystoscopy. Although some patients are content to defer surveillance decisions to their physicians, others prefer to be more involved. Future work should focus on defining patient-centered approaches to surveillance decision making.

Variation in the tendency of primary care physicians to intervene.

BACKGROUND: Research has documented dramatic variation in health care spending across the United States that has little relationship to health outcomes. Although high-spending areas have more physicians per capita, it is not known whether this disparity fully explains the differences in spending or whether individual physicians in high-spending regions have a greater tendency to intervene for their patients. We sought to measure the tendency of primary care physicians to intervene across regions that differ in their levels of local health care spending. METHODS: We used data from the Community Tracking Study Physician Survey, a telephone survey of a nationally representative sample of 5490 primary care physicians who provided care to adults in 1998-1999 (response rate 59%). Local health care spending in physicians' communities was determined by assigning each participating physician to 1 of 306 US hospital referral regions. The tendency of physicians to intervene was measured by evaluating their responses to 6 clinical vignettes in which they were asked how often they would order a test, referral, or treatment for the patient described. RESULTS: In 5 of the 6 vignettes, physicians in high-spending regions were more likely to recommend interventions than those practicing in low-spending regions. For example, for a 35-year-old man with back pain and foot drop, physicians in high-spending regions would recommend magnetic resonance imaging 82% of the time, compared with 69% for physicians in low-spending regions (P<.001). For a 60-year-old man somewhat bothered by symptoms of benign prostatic hypertrophy, physicians in high-spending regions would make a urology referral 32% of the time, while those in low-spending regions would do so only 23% of the time (P<.001). Our findings that physicians in high-spending regions have a greater tendency to intervene persisted in analyses stratified by physician specialty (family/general practice vs internal medicine). CONCLUSION: Varying rates of health care spending across the United States reflect the underlying tendency of local physicians to recommend interventions for their patients.

Screening for cervical cancer: will women accept less?

BACKGROUND: U.S. professional organizations increasingly agree that most women require Papanicolaou smear screening every 2 to 3 years rather than annually and that most elderly women may stop screening. We sought to describe the attitudes of women in the United States toward less intense screening, specifically, less frequent screening and eventual cessation of screening. METHODS: We conducted a random-digit-dialing telephone survey of women in 2002 (response rate of 75% among eligible women reached by telephone). A nationally representative sample of 360 women aged 40 years or older with no history of cancer was surveyed about their acceptance of less intense screening. RESULTS: Almost all women aged 40 years or older (99%) had had at least one Pap smear; most (59%) were screened annually. When women were asked to choose their preferred frequency for screening, 75% preferred screening at least annually (12% chose screening every 6 months). Less than half (43%) had heard of recommendations advocating less frequent screening. When advised of such recommendations, half of all women believed that they were based on cost. Sixty-nine percent said that they would try to continue being screened annually even if their doctors recommended less frequent screening and advised them of comparable benefits. Only 35% of women thought that there might come a time when they would stop getting Pap smears; of these, almost half would not stop until after age 80 years. The strongest predictor of reluctance to reduce the frequency of screening was a belief that cost was the basis of current screening frequency recommendations. CONCLUSION: Most women in the United States prefer annual Pap smears and are resistant to the idea of less intense screening. Concern that cost considerations rather than evidence form the basis of screening recommendations may partly explain women's reluctance to accept less intense screening.

Association between apple consumption and physician visits: appealing the conventional wisdom that an apple a day keeps the doctor away.

IMPORTANCE: Fruit consumption is believed to have beneficial health effects, and some claim, "An apple a day keeps the doctor away." OBJECTIVE: To examine the relationship between eating an apple a day and keeping the doctor away. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional study of a nationally representative sample of the noninstitutionalized US adult population. A total of 8728 adults 18 years and older from the 2007-2008 and 2009-2010 National Health and Nutrition Examination Survey completed a 24-hour dietary recall questionnaire and reported that the quantity of food they ate was reflective of their usual daily diet. EXPOSURES: Daily apple eaters (consuming the equivalent of at least 1 small apple daily, or 149 g of raw apple) vs non-apple eaters, based on the reported quantity of whole apple consumed during the 24-hour dietary recall period. MAIN OUTCOMES AND MEASURES: The primary outcome measure was success at "keeping the doctor away," measured as no more than 1 visit (self-reported) to a physician during the past year; secondary outcomes included successful avoidance of other health care services (ie, no overnight hospital stays, visits to a mental health professional, or prescription medications). RESULTS: Of 8399 eligible study participants who completed the dietary recall questionnaire, we identified 753 adult apple eaters (9.0%)--those who typically consume at least 1 small apple per day. Compared with the 7646 non-apple eaters (91.0%), apple eaters had higher educational attainment, were more likely to be from a racial or ethnic minority, and were less likely to smoke (P<.001 for each comparison). Apple eaters were more likely, in the crude analysis, to keep the doctor (and prescription medications) away: 39.0% of apple eaters avoided physician visits vs 33.9% of non-apple eaters (P=.03). After adjusting for sociodemographic and health-related characteristics, however, the association was no longer statistically significant (OR, 1.19; 95% CI, 0.93-1.53; P=.15). In the adjusted analysis, apple eaters also remained marginally more successful at avoiding prescription medications (odds ratio, 1.27; 95% CI, 1.00-1.63). There were no differences seen in overnight hospital stay or mental health visits. CONCLUSIONS AND RELEVANCE: Evidence does not support that an apple a day keeps the doctor away; however, the small fraction of US adults who eat an apple a day do appear to use fewer prescription medications.

Cervical cancer screening among women without a cervix.

CONTEXT: Most US women who have undergone hysterectomy are not at risk of cervical cancer-they underwent the procedure for benign disease and they no longer have a cervix. In 1996, the US Preventive Services Task Force recommended that routine Papanicolaou (Pap) smear screening is unnecessary for these women. OBJECTIVE: To determine whether Pap smear screening among women who have undergone hysterectomy has decreased following the recommendation. DESIGN: We used data from the Behavioral Risk Factor Surveillance System (1992-2002), an annual, population-based telephone survey of US adults conducted by the Centers for Disease Control and Prevention. Data about timing, type, and indication for hysterectomies were obtained from the Nationwide Inpatient Sample and other sources. STUDY PARTICIPANTS: In each year of the survey, a representative sample of US women 18 years and older who had undergone hysterectomy (combined n = 188,390) was studied. MAIN OUTCOME MEASURE: The main outcome was the proportion of women with a history of hysterectomy who reported a current Pap smear (within 3 years). Overall proportions are age adjusted to the 2002 US female population. RESULTS: Twenty-two million US women 18 years and older have undergone hysterectomy, representing 21% of the population. The proportion of these women who reported a current Pap smear did not change during the 10-year study period. In 1992 (before the US Preventive Services Task Force recommendations), 68.5% of women who had undergone hysterectomy reported having had a Pap smear in the past 3 years; in 2002 (6 years after the recommendation), 69.1% had had a Pap smear during the same period (P value for the comparison =.22). After accounting for Pap smears that may have preceded a recent hysterectomy and hysterectomies that spared the cervix or were performed for cervical neoplasia, we estimate that almost 10 million women, or half of all women who have undergone hysterectomy, are being screened unnecessarily. CONCLUSIONS: Many US women are undergoing Pap smear screening even though they are not at risk of cervical cancer. The US Preventive Services Task Force recommendations either have not been heard or have been ignored.

The association between residency training and internists' ability to practice conservatively.

IMPORTANCE: Growing concern about rising costs and potential harms of medical care has stimulated interest in assessing physicians' ability to minimize the provision of unnecessary care. OBJECTIVE: To assess whether graduates of residency programs characterized by low-intensity practice patterns are more capable of managing patients' care conservatively, when appropriate, and whether graduates of these programs are less capable of providing appropriately aggressive care. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional comparison of 6639 first-time takers of the 2007 American Board of Internal Medicine certifying examination, aggregated by residency program (n = 357). EXPOSURES: Intensity of practice, measured using the End-of-Life Visit Index, which is the mean number of physician visits within the last 6 months of life among Medicare beneficiaries 65 years and older in the residency program's hospital referral region. MAIN OUTCOMES AND MEASURES: The mean score by program on the Appropriately Conservative Management (ACM) (and Appropriately Aggressive Management [AAM]) subscales, comprising all American Board of Internal Medicine certifying examination questions for which the correct response represented the least (or most, respectively) aggressive management strategy. Mean scores on the remainder of the examination were used to stratify programs into 4 knowledge tiers. Data were analyzed by linear regression of ACM (or AAM) scores on the End-of-Life Visit Index, stratified by knowledge tier. RESULTS: Within each knowledge tier, the lower the intensity of health care practice in the hospital referral region, the better residency program graduates scored on the ACM subscale (P < .001 for the linear trend in each tier). In knowledge tier 4 (poorest), for example, graduates of programs in the lowest-intensity regions had a mean ACM score in the 38th percentile compared with the 22nd percentile for programs in the highest-intensity regions; in tier 2, ACM scores ranged from the 75th to the 48th percentile in regions from lowest to highest intensity. Graduates of programs in low-intensity regions tended, more weakly, to score better on the AAM subscale (in 3 of 4 knowledge tiers). CONCLUSIONS AND RELEVANCE: Regardless of overall medical knowledge, internists trained at programs in hospital referral regions with lower-intensity medical practice are more likely to recognize when conservative management is appropriate. These internists remain capable of choosing an aggressive approach when indicated.

Aspirin versus anticoagulation for prevention of venous thromboembolism major lower extremity orthopedic surgery: a systematic review and meta-analysis.

BACKGROUND: Hip fracture surgery and lower extremity arthroplasty are associated with increased risk of both venous thromboembolism and bleeding. The best pharmacologic strategy for reducing these opposing risks is uncertain. PURPOSE: To compare venous thromboembolism (VTE) and bleeding rates in adult patients receiving aspirin versus anticoagulants after major lower extremity orthopedic surgery. DATA SOURCES: Medline, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library through June 2013; reference lists, ClinicalTrials.gov, and scientific meeting abstracts. STUDY SELECTION: Randomized trials comparing aspirin to anticoagulants for prevention of VTE following major lower extremity orthopedic surgery. DATA EXTRACTION: Two reviewers independently extracted data on rates of VTE, bleeding, and mortality. DATA SYNTHESIS: Of 298 studies screened, 8 trials including 1408 participants met inclusion criteria; all trials screened participants for deep venous thrombosis (DVT). Overall rates of DVT did not differ statistically between aspirin and anticoagulants (relative risk [RR]: 1.15 [95% confidence interval {CI}: 0.68-1.96]). Subgrouped by type of surgery, there was a nonsignificant trend favoring anticoagulation following hip fracture repair but not knee or hip arthroplasty (hip fracture RR: 1.60 [95% CI: 0.80-3.20], 2 trials; arthroplasty RR: 1.00 [95% CI: 0.49-2.05], 5 trials). The risk of bleeding was lower with aspirin than anticoagulants following hip fracture repair (RR: 0.32 [95% CI: 0.13-0.77], 2 trials), with a nonsignificant trend favoring aspirin after arthroplasty (RR: 0.63 [95% CI: 0.33-1.21], 5 trials). Rates of pulmonary embolism were too low to provide reliable estimates. CONCLUSION: Compared with anticoagulation, aspirin may be associated with higher risk of DVT following hip fracture repair, although bleeding rates were substantially lower. Aspirin was similarly effective after lower extremity arthroplasty and may be associated with lower bleeding risk. Journal of Hospital Medicine 2014;9:579-585. © 2014 Society of Hospital Medicine.

Too Little? Too Much? Primary care physicians' views on US health care: a brief report.

BACKGROUND: Some believe that a substantial amount of US health care is unnecessary, suggesting that it would be possible to control costs without rationing effective services. The views of primary care physicians-the frontline of health care delivery-are not known. METHODS: Between June and December 2009, we conducted a nationally representative mail survey of US primary care physicians (general internal medicine and family practice) randomly selected from the American Medical Association Physician Masterfile (response rate, 70%; n=627). RESULTS: Forty-two percent of US primary care physicians believe that patients in their own practice are receiving too much care; only 6% said they were receiving too little. The most important factors physicians identified as leading them to practice more aggressively were malpractice concerns (76%), clinical performance measures (52%), and inadequate time to spend with patients (40%). Physicians also believe that financial incentives encourage aggressive practice: 62% said diagnostic testing would be reduced if it did not generate revenue for medical subspecialists (39% for primary care physicians). Almost all physicians (95%) believe that physicians vary in what they would do for identical patients; 76% are interested in learning how aggressive or conservative their own practice style is compared with that of other physicians in their community. CONCLUSIONS: Many US primary care physicians believe that their own patients are receiving too much medical care. Malpractice reform, realignment of financial incentives, and more time with patients could remove pressure on physicians to do more than they feel is needed. Physicians are interested in feedback on their practice style, suggesting they may be receptive to change. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00853918.

Health behaviors and utilization among users of complementary and alternative medicine for treatment versus health promotion.

OBJECTIVE: To compare the characteristics, health behaviors, and health services utilization of U.S. adults who use complementary and alternative medicine (CAM) to treat illness to those who use CAM for health promotion. DATA SOURCE: The 2007 National Health Interview Survey (NHIS). STUDY DESIGN: We compared adult (age ≥18 years) NHIS respondents based on whether they used CAM in the prior year to treat an illness (n=973), for health promotion (n=3,281), or for both purposes (n=3,031). We used complex survey design methods to make national estimates and examine respondents' self-reported health status, health behaviors, and conventional health services utilization. PRINCIPAL FINDINGS: Adults who used CAM for health promotion reported significantly better health status and healthier behaviors overall (higher rates of physical activity and lower rates of obesity) than those who used CAM as treatment. While CAM Users in general had higher rates of conventional health services utilization than those who did not use CAM; adults who used CAM as treatment consumed considerably more conventional health services than those who used it for health promotion. CONCLUSION: This study suggests that there are two distinct types of CAM User that must be considered in future health services research and policy decisions.
