Primary care physicians' awareness and adherence to cervical cancer screening guidelines in Texas.

BACKGROUND: Cervical cancer screening guidelines were created to help healthcare professionals in appropriate screening utilizing the PAP test. However, significant variation in cervical cancer screening among primary care physicians has been noted. Knowledge of the awareness of and adherence to cervical cancer screening guidelines by primary care physicians will help determine how best to disseminate and educate these physicians regarding the guidelines in hopes of reducing unnecessary screening and improving screening for under screened populations. METHODS: A cross-sectional, mailed survey involving Family Medicine (FP), Community Internal Medicine (CIM), and Obstetrics/Gynecology (OB) physicians practicing in a large University-affiliated, multi-specialty group practice associated with an 186,000-member HMO in Central Texas (n = 177) was conducted in 2001-2002. RESULTS: Most physicians performed PAP testing (50.4%). PAP screening was noted to vary significantly by specialty (P < 0.0001). All OBs were aware of at least one published guideline, compared to 96% of FPs and 91% of CIMs (P < 0.05). A wide variation was reported regarding adherence to published guidelines. In addition, there was significant intraspecialty variation regarding adherence to the physicians' own specialty's guidelines. CONCLUSIONS: While most physicians in the primary care setting perform PAP tests and are aware of published guidelines for PAP screening, adherence to the published guidelines varies considerably even in the same clinical setting.

E-mail communications in primary care: what are patients' expectations for specific test results?

OBJECTIVES: The objectives of this study were to assess patients' willingness to use e-mail to obtain specific test results, assess their expectations regarding response times, and identify any demographic trends. METHODS: A cross-sectional survey of primary care patients was conducted in 19 clinics of a large multi-specialty group practice associated with an 186,000-member Health Maintenance Organization. The outcome measures were proportion of patients with current e-mail access, their willingness to use it for selected general clinical services and to obtain specific test results, and their expectations of timeliness of response. RESULTS: The majority of patients (58.3%) reported having current e-mail access and indicated strong willingness to use it for communication. However, only 5.8% reported having ever used it to communicate with their physician. Patients were most willing to use e-mail to obtain cholesterol and blood sugar test results, but less willing to use it to obtain brain CT scan results. Patients' expectations of timeliness were generally very high, particularly for high-stakes tests such as brain CT scan. Significant differences of willingness and expectations were found by age group, education, and income. CONCLUSIONS: These findings indicate that most patients are willing to use e-mail to communicate with their primary care providers even for specific test results and that patients will hold providers to high standards of timeliness regarding response. The implication is that integration of e-mail communications into primary care ought to assure prompt and accurate patient access to a plethora of specific clinical services.

Physician response to written feedback on a medication discrepancy found with their elderly ambulatory patients.

OBJECTIVES: To assess physicians' responses to written feedback on medication discrepancies found with their elderly ambulatory patients. DESIGN: Cross-sectional survey. SETTING: Four clinics of a large university-affiliated, multispecialty group practice associated with a 186,000-member health maintenance organization. PARTICIPANTS: Patients aged 65 and older (n=202) and their family physicians (n=32). MEASUREMENTS: Medication discrepancies and physicians' responses to written feedback on letters and adhesive labels containing a list of patients' actual medications. RESULTS: A medication discrepancy was identified with 171 of 202 patients (84.7%). They resulted from patients not taking charted medications (52.9%), patients taking medications that were not charted (34.3%), or difference in dosage and/or schedule (12.8%). The medications involved were mostly complementary/alternative (28.3%), respiratory/allergy (15.1%), and analgesics (14.1%). The majority of physicians reported that the letters (93.8%) and accompanying labels (90.6%) were helpful to them. Half of the physicians reported filing the letters in patients' charts, whereas the other half discarded them. The majority (93.8%) also perceived the labels as an additional benefit to their practice and placed them in patients' charts to be used to correct patients' medications. Receptivity to the feedback was unrelated to physician age group, sex, years in practice, or clinic of practice. CONCLUSION: Although medication discrepancies are common in elderly ambulatory patients, their family physicians appreciate assistance in correcting these discrepancies, although potential problems, such as cultural or organizational resistance to the open disclosure of medication discrepancies in medical records due to associated legal ramifications, may need to be resolved.

Variation in MRI/CT utilization among FAMILY physicians and general internists in a multi-specialty group practice.

BACKGROUND: The objective of this study was to examine variations in MRI/CT utilization between family physicians (FPs) and general internists (IMs) within a multi-specialty group practice. MATERIAL/METHODS: Using administrative data, we computed ordering rates of MRI/CT per 1,000 outpatient clinic visits and per 1,000 unique patients and rate ratios (RR) to compare rates between 34 FPs and 24 IMs practicing in 7 clinics located within 50 miles of the radiology facility. We also assessed intra-specialty variation. Sources and degree of variation were determined separately for FPs and IMs through multivariate linear regression modeling. RESULTS: The IMs ordered MRI/CTs at twice the rate of FPs (29.6 vs. 14.8 per 1,000). Although the absolute ranges by specialty were statistically similar, the variance was significantly higher for IMs (86.1 vs. 52.3; p<0.0001). FPs' ordering rates ranged from 2.8 to 35.2 (SD=7.23), while IMs' ranged from 16.0 to 47.9 (SD=9.27). Female physicians ordered the tests at a higher rate (RR=1.38; 95% CI=1.17-1.53). After controlling for physician gender, years of practice, and patient panel size, distances from their clinics to the radiology facility site and patient severity index were the only variables that were significantly associated with MRI/CT ordering among FPs, explaining 39% of the total variance. CONCLUSIONS: Although IMs ordered MRI/CTs at a higher rate, as were females from both specialties, there was a higher ratio between high and low FP utilizers. The variation in FPs can be partly explained by their clinic distance to the radiology facility site and their patient severity index.

Nonclinical factors associated with primary care physicians' ordering patterns of magnetic resonance imaging/computed tomography for headache.

RATIONALE AND OBJECTIVES: The purpose of ordering an imaging test for headache, which is one of the most common reasons for patient consultation with a primary care physician (PCP), include medical indications as well as patient anxiety and medico-legal concerns. The impact of nonclinical factors on PCPs' ordering patterns of magnetic resonance imaging/computed tomography for patients presenting with a headache was examined. MATERIALS AND METHODS: A retrospective record review of all patients treated for headache as their primary complaint by a PCP from a multispecialty group practice associated with an 180,000-member Health Maintenance Organization during calendar year 2000 was examined. The practice included 18 clinics. Logistic regression was used to estimate the association between physician ordering patterns of imaging tests and patient, physician, and clinic setting characteristics. RESULTS: Of the total study subjects (n = 4,372), a magnetic resonance imaging/computed tomography imaging test was ordered for 5.3%. At their first encounter, patient's gender, site of care, and insurance status under the health care system's Health Maintenance Organization had statistically significant associations with the likelihood of imaging test orders. Female physicians were less likely to order an imaging test (OR = 0.65; 95% confidence interval, 0.39-1.08). For subsequent encounters, however, site of care was the only nonclinical factor that had a consistent association with the likelihood of having a magnetic resonance imaging/computed tomography ordered. CONCLUSION: These data show that a number of nonclinical factors may have been associated with having an imaging test ordered by a PCP when patients presented with a headache. These factors were more significant when the patient was being seen for the first time with this complaint.

Identifying opportunities for improved colorectal cancer screening in primary care.

BACKGROUND: Although current recommendations advocate screening persons 50 years of age or older for colorectal cancer (CRC), actual screening practice is highly variable among primary care physicians (PCPs). Knowledge of the factors that influence whether or not screening is offered during a clinic visit is essential to develop effective screening strategies. METHODS: A cross-sectional telephone survey of one in four randomly selected patients aged 50 years or older (n = 400) attending a primary care clinic within an integrated health care system in central Texas was conducted. A survey of all PCPs (n = 32) at the practice sites was also administered. RESULTS: The visit type was an important determinant of whether CRC screening was discussed, with most discussion occurring during visits for physicals (P < 0.0001). This finding was corroborated by the physician survey. Patient age and education were also associated with a higher likelihood of having been offered CRC screening (P = 0.009 and 0.014, respectively). Patient race, gender, primary language, PCP, or clinics attended were not significantly associated with the discussion of CRC screening. CONCLUSIONS: Discussions regarding CRC screening are most likely to occur during preventive care visits. Thus, facilitating preventive visits especially for the elderly represents an opportunity to improve CRC screening rates in primary care practice.

School backpack weights: a survey of students in Ghana, Guatemala and the USA.

Cross-sectional studies were conducted in conveniently selected schools in Ghana, Guatemala, and the USA to quantify and compare the percentage of body weight carried by students in their backpacks as well as assess parental knowledge of the backpack weights and contents. Mean backpack weights varied significantly by country and increased significantly with increasing student grade. In the USA, girls significantly carried heavier backpacks (p <.0001). The backpack loads represented an average of 7.7% (95% CI = 7.4-8.0), 9.7% (95% CI = 9.2-10.2), and 9.4% (95% CI = 9.1-9.8) of student body weights in Ghana, Guatemala, and the USA, respectively. No student in Ghana carried a wheeled backpack in contrast to 6% and 2.8%, respectively, in Guatemala and the USA. In Ghana, 4.1 and 73.6% of parents were reported to be aware of their children's backpack weights and contents, respectively, compared to 21.9 and 57.5% in Guatemala, and 7.7 and 55.3% in the USA. Backpack loads respresent a significant percentage of the body weights of students in all three countries. The vast majority of parents are unaware of their child's backpack weight.

Teaching medical students complementary and alternative medicine using evidence-based principles.

OBJECTIVES: Introducing new ideas such as complementary and alternative medicine (CAM) and evidence-based medicine (EBM) to medical students early in their education may help to nurture their interest. This study evaluated the effectiveness of teaching CAM using EBM principles and assessed changes in student perceived knowledge, attitudes, and skills following a new curriculum on CAM. DESIGN: A before-and-after evaluation using a one-page, anonymous questionnaire. SETTING AND SUBJECTS: All third year students of a state, public medical school in Texas. INTERVENTION: A new curriculum comprising interactive sessions on CAM, EBM, and basic principles of epidemiology and biostatistics. OUTCOME MEASURES: Changes in student-perceived knowledge, attitudes, and skills. RESULTS: Of 67 students, complete data were obtained for 54 (81%). The majority reported that the new instruction in CAM (98%), EBM (96%), biostatistics (91%), and epidemiology (87%) would be of some benefit in their future work. Significant changes were reported in the areas of appraising a clinical trial (p < 0.0001), critiquing the medical literature (p < 0.01), and the appropriateness of integrating EBM and CAM in the medical school curriculum (p < 0.05). There were modest increases in the mean responses on their skill level in reading/understanding the medical literature (3.40-3.52), comfort level in reading the medical literature (3.53-3.67), and preparedness in designing a research study (2.12-2.39) based on a five-point Likert scale, although not statistically significant. CONCLUSIONS: Medical students could be effectively taught CAM using EBM principles. In addition, a short, interactive curriculum on an important topic has a positive impact on medical students' desires to acquire new knowledge. This should be a good motivational message to family medicine educators regarding the contribution to new knowledge such as CAM.

Percentage of body weight carried by students in their school backpacks.

OBJECTIVE: To determine the percentage of body weight represented by backpacks and the types of backpacks carried by elementary school students. DESIGN: A cross-sectional study was conducted in three elementary schools in central Texas. All students in kindergarten through fifth grade were invited to participate. A letter, with no direct mention of backpack weighing, was sent to each parent for written consent. Student weights and heights and their backpack weights were measured by trained research assistants. RESULTS: The mean backpack weights, which increased significantly with increasing grade level, varied significantly by school, backpack type, day of week, body mass index, and race/ethnicity. The backpack loads represented an average of 8.2% (95% confidence interval, 7.8-8.5) of student body weights but increased significantly with increasing grade level, from 6.2% among kindergarteners to 12.0% among fifth graders. Twenty-six percent of students carried backpacks that weighed at least 10% of their body weights. A total of 25 students (3.5%) had backpacks with wheels. Wheeled backpack users were significantly older and more likely to be girls or from school B. Concern about weight was the most popular reason cited for using a wheeled backpack. CONCLUSIONS: Backpack loads represent a significant percentage of body weight of this sample of students aged 5-12 yr. Some students are already using wheeled backpacks, which may have their own hazards.

Parent-child concordance on reported barriers to helmet use by children.

BACKGROUND: We determined the agreement between parents and their school-age children on reported barriers to bicycle helmet use. MATERIAL/METHODS: We conducted a cross-sectional survey in a 2-county Central Texas region with no helmet use legislation. Parent-child pairs, selected through a randomized, multi-stage sampling procedure and pre-matched by unique identifiers, were surveyed independently with self-administered questionnaires. Parent-child concordance was assessed using Kappa statistic. RESULTS: Of 1,987 surveys distributed, children returned 1,203 (61%) while parents returned 636 (53% of child respondents). Parents included 31% college graduates and 33% reported annual income of >55,000 dollars. Children included 60% whites, 16% blacks, and 16% Hispanics. The most popular reasons cited by children as barriers to helmet use were not having one (34%), being a safe rider (31%), and helmets messing up hair (18%). Good concordance was found on reported child bicycle riding (parent=88.0% vs. child=88.0%; K=0.64) and child helmet use the last time child rode a bicycle (parent=25.1% vs. child=28.0%; K=0.54). While good concordance was also found for reported helmet ownership (parent=31.9% vs. child=29.9%; K= 0.50), poor concordance was found for other barriers to helmet use including helmets looking ugly (parent=6.5% vs. child=13.4%; K=0.38) and messing up hair (parent=5.6% vs. child=15.2%; K=0.36). CONCLUSIONS: Although parents may be generally aware of their children's bicycle riding and helmet use habits, they may not be fully aware of the reasons why their children may not use a helmet. Public education and interventions on helmet promotion need to focus on parents.

Helmet use: a survey of 4 common childhood leisure activities.

OBJECTIVE: To compare the distribution and observation of helmet use patterns among 4 common childhood leisure activities-bicycle riding, in-line skating, skateboarding, and scooter riding-in a setting with no helmet use legislation. DESIGN: A cross-sectional, unobtrusive, direct observation of children engaged in 1 of the 4 activities was conducted during an 8-week period. SETTING: Eight communities of at least 1000 persons each in a 2-county Central Texas area. MAIN OUTCOME MEASURES: Prevalence of activity, helmet use, and correct helmet use. RESULTS: Of 841 children observed, most rode bicycles (74.8%); only 4.2% rode skateboards. They included 127 children estimated to be younger than 6 years (15.1%) and 495 estimated to be aged between 6 and 12 years (58.9%). Most were male (67.3%) and observed in urban communities (61.7%). The locations of highest concentration of the 4 activities were minor streets for bicycle riding, playgrounds for in-line skating, and sidewalks for skateboarding and scooter riding. The rate of overall helmet use was 13.6% and did not vary significantly by activity: in-line skating, 18.2%; skateboarding, 14.3%; bicycle riding, 13.5%; and scooter riding, 11.5%. However, the observed correct helmet use prevalence of 72.6% differed significantly by activity. Most children riding scooters wore their helmets incorrectly. Helmet use was positively associated with helmet use by accompanying children and/or adults. CONCLUSIONS: While bicycle riding was the most popular activity observed, helmet use was most prevalent among in-line skaters and least prevalent among scooter riders, many of whom also wore them incorrectly. Observed helmet use was influenced mostly by adult and peer helmet use, indicating that public education and interventions should target children and their parents as well as scooter riders.

Traffic-related injury prevention interventions for low-income countries.

Traffic-related injuries have become a major public health concern worldwide. However, unlike developed or high-income countries (HICs), many developing or low-income countries (LICs) have made very little progress towards addressing this problem. Lack of the progress in LICs is attributable, in part, to their economic situation in terms of their governments' lack of resources to invest in traffic safety, cultural beliefs regarding the fatalism of injuries, competing health problems particularly with the emergence of HIV/AIDS, distinctive traffic mixes comprising a substantial number of vulnerable road users for whom less research has been done, low literacy rates precluding motorists to read and understand road signs, and peculiar political situations occasionally predominated by dictatorship and non-democratic governments. How then can LICs tackle the challenge of traffic safety from the experiences of HICs without reinventing the wheel? This paper reviews selected interventions and strategies that have been developed to counter traffic-related injuries in HICs in terms of their effectiveness and their applicability to LICs. Proven and promising interventions or strategies such as seat belt and helmet use, legislation and enforcement of seat belt use, sidewalks, roadway barriers, selected traffic-calming designs (e.g., speed ramps/bumps), pedestrian crossing signs combined with clearly marked crosswalks, and public education and behavior modification targeted at motorists are all feasible and useable in LICs as evidenced by data from many LICs. While numerous traffic-related injury policy interventions and strategies developed largely in HICs are potentially transferable to LICs, it is important to consider country-specific factors such as costs, feasibility, sustainability, and barriers, all of which must be factored into the assessment of effectiveness in specific LIC settings. Almost all interventions and strategies that have been proven effective in HICs will need to be evaluated in LICs and particular attention paid to the effectiveness of enforcement measures. It behooves LIC governments, however, to ensure that only standard, approved safety devices like helmets are imported into their countries. Additionally, LICs may need to improvise and innovate in the traffic safety technology transfer.

Effects of using free sample medications on the prescribing practices of family physicians.

INTRODUCTION: We determined whether family physicians (FPs) who distribute free sample medications are more likely to prescribe those medications than physicians who do not. METHODS: We reviewed administrative health plan prescription data of three similar clinics with 23 FPs within a comprehensive health care delivery system. Only clinic X physicians dispensed free sample medications. To determine which prescribed medications to study, the sample medications log from clinic X was categorized. The 25 sample medications most frequently dispensed by category were selected as study medications. Outcome measures included the number, proportion, cost, and formulary status of study medications prescribed and the average 30-day prescription costs. RESULTS: Physicians at clinic X prescribed the largest proportion of prescriptions for study medications, the smallest proportion of preferred name brands among study medications, and had the highest costs for prescriptions of non-listed formulary study medications (P < .0001). The average 30-day prescription costs differed significantly by clinic (P < .0001), with clinic X being the highest. There was a significant association between the number of samples dispensed and the number of prescriptions written for study medications by physicians at clinic X (P = .006). CONCLUSIONS: Our data support the conclusion that FPs who distribute free samples are more likely to prescribe those medications than their counterparts who do not.
