Predicting Dental Caries in Young Children in Primary Health Care Settings.

Young children need increased access to dental prevention and care. Targeting high caries risk children first helps meet this need. The objective of this study was to develop a parent-completed, easy-to-score, short, accurate caries risk tool for screening in primary health care settings to identify children at increased risk for cavities. A longitudinal, prospective, multisite, cohort study enrolled (primarily through primary health care settings) and followed 985 (out of 1,326) 1-y-old children and their primary caregivers (PCGs) until age 4. The PCG completed a 52-item self-administered questionnaire, and children were examined using the International Caries Detection and Assessment Criteria (ICDAS) at 12 ± 3 mo (baseline), 30 ± 3 mo (80% retention), and 48 ± 3 mo of age (74% retention). Cavitated caries lesion (dmfs = decayed, missing, and filled surfaces; d = ICDAS ≥3) experience at 4 y of age was assessed and tested for associations with questionnaire items using generalized estimating equation models applied to logistic regression. Multivariable analysis used backward model selection, with a limit of 10 items. At age 4, 24% of children had cavitated-level caries experience; 49% were female; 14% were Hispanic, 41% were White, 33% were Black, 2% were other, and 10% were multiracial; 58% enrolled in Medicaid; and 95% lived in urban communities. The age 4 multivariable prediction model, using age 1 responses (area under the receiver operating characteristic curve = 0.73), included the following significant (P < 0.001) variables (odds ratios): child participating in public assistance programs such as Medicaid (1.74), being non-White (1.80-1.96), born premature (1.48), not born by caesarean section (1.28), snacking on sugary snacks (3 or more/d, 2.22; 1-2/d or weekly, 1.55), PCG cleaning the pacifier with juice/soda/honey or sweet drink (2.17), PCG daily sharing/tasting food with child using same spoon/fork/glass (1.32), PCG brushing their teeth less than daily (2.72), PCG's gums bleeding daily when brushing or PCG having no teeth (1.83-2.00), and PCG having cavities/fillings/extractions in past 2 y (1.55). A 10-item caries risk tool at age 1 shows good agreement with cavitated-level caries experience by age 4.

Predicting Caries in Medical Settings: Risk Factors in Diverse Infant Groups.

Expanded partnership with the medical community is a promising strategy for reducing disparities in dental caries among young children. However, no validated caries risk instrument exists for use in primary health care settings. To help resolve this gap, a 52-item caries risk questionnaire was developed and targeted to primary caregivers (PCGs) to test in a 3-y prospective study. To begin to understand the validity of the questionnaire items, the purpose of this study was to compare responses to the questionnaire based on key demographic characteristics known to be associated with disparities in caries experience (e.g., race/ethnicity and insurance status). A total of 1,323 one-year-old children were recruited primarily through 3 medical research networks. Baseline questionnaire responses were analyzed via logistic regression. The sample was 49% female. Its racial/ethnic makeup was as follows: 13% Hispanic, 37% White, 37% Black, and 13% other or multiracial. Sixty-one percent were enrolled in Medicaid, and 95% resided in urban communities. Mothers represented 94% of PCGs. There were significant differences ( P < 0.05) in baseline responses based on Medicaid status and race/ethnicity. As compared with those not enrolled in Medicaid, children in the Medicaid group were significantly more likely (after adjusting for race/ethnicity) to 1) go to sleep while nursing or drinking something other than water, 2) eat sugary snacks between meals, 3) consume sugary drinks between meals, 4) receive topical fluoride from a health professional, 5) visit the dentist, and 6) not have an employed adult in the household. PCGs of children enrolled in Medicaid were significantly more likely to be the mother, have bleeding gums, eat sugary snacks between meals, consume sugary drinks between meals, eat or drink something other than water before going to bed, and not get regular dental checkups. In conclusion, there are significant differences in caries risk questionnaire responses based on Medicaid status and race/ethnicity that provide construct and criterion validity to the developed caries risk tool (ClinicalTrials.gov NCT01707797).

Fluoride Use in Health Care Settings: Association with Children's Caries Risk.

Expanded partnership with the medical community is an important strategy for reducing dental caries disparities. The purpose of this study was to assess the relationship between fluoride (F) "in office" (drops/tablets and/or varnish), as prescribed or applied by a health care professional by age 1 y, and 1) caries development and 2) presence of other caries risk factors or mediators (e.g., socioeconomic status). Child-primary caregiver (PCG) pairs ( N = 1,325) were recruited in Indiana, Iowa, and North Carolina as part of a longitudinal cohort study to validate a caries risk tool for primary health care settings. PCGs completed a caries risk questionnaire, while children received caries examinations per the criteria of the International Caries Detection and Assessment System at ages 1, 2.5, and 4 y. Baseline responses regarding children's history of F in office were tested for association with other caries risk variables and caries experience at ages 2.5 and 4 y via generalized estimating equation models applied to logistic regression. The sample was 48% female, and many children (61%) were Medicaid enrolled. The prevalence of cavitated caries lesions increased from 7% at age 2.5 y to 25% by age 4 y. Children who received F in office were likely deemed at higher caries risk and indeed were significantly ( P < 0.01) more likely to develop cavitated caries lesions by ages 2.5 and 4 y, even after F application (odds ratios: 3.5 and 2.3, respectively). Factors significantly associated with receiving F included the following: child being Medicaid enrolled, not having an employed adult in the household, child and PCG often consuming sugary drinks and snacks, and PCG having recent caries experience. Increased F in office from a health care provider by age 1 y was associated with known caries risk factors. Most (69%) children had never been to the dentist, suggesting that risk factors could be alerting medical providers and/or parents, thereby affecting in-office F recommendations. Differences among states could also be related to state-specific F-varnish reimbursement policies (ClinicalTrials.gov NCT01707797).

Is use of hormone replacement therapy associated with increased detection of human papillomavirus and potential risk of HPV-related genital cancers?

Oral contraceptives (OC) are a risk factor for female genital cancers and in vivo studies have shown that progestins stimulate human papillomavirus (HPV) gene expression. A similar role for hormone replacement therapy (HRT) has received little evaluation. Cervical/vaginal specimens were obtained to detect HPV from postmenopausal women (n = 429) seeking annual gynaecologic care. HPV was detected in 14% of women and 4.4% had high-risk, oncogenic types. HPV prevalence was similar across current, past and never HRT users. After adjustment for HPV-related risk factors, current and past user status showed no increased viral detection compared with never users. HRT duration also did not elevate risk among current users. However, longer duration (adj. OR 1.5/year, 95% CI 1.0-2.3) and longer latency (adj. OR 1.2/year, 95% CI 0.9-1.7) among past users of oestrogen/progestin regimens were associated with greater risk. Overall use of HRTs was not associated with HPV detection or disease. However, past users of combination HRTs had significantly greater risk of HPV detection with longer HRT duration and latency, similar to OC-HPV findings. The recommendation that postmenopausal women continue HRTs long term may lead to an increased development of HPV-related diseases, of particular concern among those who discontinue HRTs and subsequent gynaecologic care for early cancer detection.

Quality of a family medicine preceptorship is significantly associated with matching into family practice.

OBJECTIVES: This study tested whether clinical experiences in family practice are associated with matching into family practice. METHODS: We conducted a prospective cohort study of 913 medical students who completed the Family Practice Preceptorship (FPP) at the University of Iowa from 1990-1996. Using univariate techniques and logistic regression, we compared the background and experiences of those who matched into family practice with those who chose other specialties. RESULTS: Twenty-nine percent (n=267) matched into family practice. Positive independent predictors of family practice match were hometown size less than 10,000 (odds ratio [OR] 1.8), anticipating choosing family practice at matriculation (OR 4.2), and liking to help others (OR 4.1). Negative independent predictors included parental income of at least $120,000 (OR .61), desiring to perform technical procedures (OR .51), and liking the scientific method and research (OR .54). The effect of an early summer clinical experience at a community hospital varied depending on the level of student interest in family practice at matriculation. Students who rated the educational value of the FPP as high or very high were significantly more likely to go into family practice (OR 2.9), even after adjusting for all other student characteristics. CONCLUSIONS: A number of student characteristics and preferences, early clinical experiences, and the perceived quality of a required family medicine preceptorship were significantly and independently associated with students matching into family practice.

Magnitude and variability of sequential estradiol and progesterone concentrations in women using depot medroxyprogesterone acetate for contraception.

OBJECTIVE: To describe the magnitude and variability of sequential serum estradiol and progesterone concentrations throughout one depot medroxyprogesterone (DMPA) injection interval. DESIGN: Prospective study. SETTING: Family planning and women's health clinics. PATIENT(S): Thirty-one women, ages 19 to 46, using DMPA for contraception. INTERVENTION(S): Serum for estrogen and progesterone was collected weekly throughout one DMPA injection interval. MAIN OUTCOME MEASURE(S): Serum estradiol and progesterone concentrations; estradiol patterns produced from data plotted across the entire DMPA injection interval. RESULT(S): The average daily estradiol concentrations ranged from 7.9 to 69.1 pg/mL, with a mean of 18.9 +/- 12.9 and a median of 15.4 pg/mL. Average daily progesterone concentrations ranged from 0.14 to 1.1 ng/mL, with a mean of 0.40 +/- 0.19 ng/mL and a median of 0.36 ng/mL. Two general patterns of estradiol concentrations were identified. One pattern, observed in approximately one third of the participants, reflected estradiol concentrations that were extremely low (mean, 12.7 +/- 3.6 pg/mL; median, 13.4 pg/mL) and consistently flat across the DMPA injection interval. The second pattern, seen in the remaining participants, reflected estradiol concentrations that were higher (mean, 22.2 +/- 14.9 pg/mL; median, 17.3 pg/mL) and quite variable. CONCLUSION(S): This study demonstrated that estradiol concentrations were lower than the 40 to 50 pg/mL reported in most studies and, for the majority of women, varied substantially across the DMPA injection interval.

A prospective study of antibiotic use and associated infections in young children.

This study examines antibiotic usage and associated infections in infants and young children in Iowa. Longitudinal data were collected using a cohort recruited at birth from eight hospitals in eastern Iowa. Parents of recruited children were mailed questionnaires at 6 weeks, and 3, 6, 9, 12, 16, and 20 months of age. The cumulative incidence of antibiotic use and associated infections was determined using Kaplan-Meier survival analysis. There were data on 1,368 children. Antibiotic use was common in our cohort and increased with age. Beginning at age 3 months, approximately 50% of the cohort was exposed to an antibiotic during each reporting period. Otitis media was the most common indication and was responsible for 67.3% of antibiotic use. Children were most frequently treated with amoxicillin, followed by the cephalosporins and sulphonamides. By 12 and 20 months of age 79.0% and 92.5% of the children, respectively, had been treated with at least one course of antibiotics. Children received antibiotics for a median of 43 days by 20 months of age. Males were more likely to experience any antibiotic exposure than females (hazard ratio = 1.18) and showed a trend for more days of use (P = 0.052). There was a small but significant variation in antibiotic usage in the different recruitment communities (P = 0.02).

Human papillomavirus in the oral cavities of children and adolescents.

OBJECTIVE: The purpose of this pilot study was to determine the frequency of human papillomavirus (HPV) in the oral cavities of children and adolescents and to identify potential risk factors for HPV infection. STUDY DESIGN: Sociodemographic information was obtained on 268 healthy infants, children, and adolescents who were < or = 20 years old. Oral squamous cells were collected from swabs with young children and from oral saline solution rinses with older children and adolescents. Extracted DNA was evaluated for HPV by polymerase chain reaction, dot blot hybridization, and DNA sequencing. Factors associated with the presence of HPV were tested by using chi(2), Fisher's exact test, and logistic regression tests. RESULTS: HPV was detected in 6.0% of the participants. HPV frequency among young children (<7 years old) was 8.7% (11/127), and among adolescents (13-20 years old) it was 5.2% (5/97). HPV was not detected in children aged 7 to 12 years old (0/44). Fifty-four percent (6/11) of HPV-positive children were 1 year of age or less; 3 of the HPV-positive children (<7 years old) were delivered by cesarean section. No statistically significant association was found between the detection of HPV in the oral cavity and method of delivery or gender; parent's race, education, HPV-related conditions, smoking history, or number of sex partners; or adolescent's smoking history or history of sexual activity. CONCLUSIONS: This study suggests that HPV is present in the oral cavity primarily in children 2 years old and younger and in adolescents 13 years and older. Cesarean delivery was not protective against oral HPV infection; in fact, half of the HPV-positive infants were born by cesarean delivery.

Effect of a patient's psychiatric history on physicians' estimation of probability of disease.

A questionnaire was mailed to 300 Iowa family physicians to determine the influence of a prior psychiatric history on decision making. The response rate was 77%. Respondents were less likely to believe that a patient had serious illness when presenting with a severe headache or abdominal pain if the patient had a prior history of depression ( P <.05) or prior history of somatic complaints ( P <. 05), compared with a patient with no past history. Respondents were less likely to report that they would order testing for a patient with headache or abdominal pain if the patient had a history of depression ( P <.05, P =.08, respectively) or somatic complaints ( P <.01). Differences in likelihood of ordering tests were not significant after adjusting for differences in estimated probability of disease. We conclude that physicians respond differently to patients with psychiatric illness because of their estimation of pretest probability of disease rather than bias. We conclude that past psychiatric history influences physicians' estimation of disease presence and willingness to order tests.

Analysis of questions asked by family physicians regarding patient care.

Objectives To characterize the information needs of family physicians by collecting the questions they asked about patient care during consultations and to classify these in ways that would be useful to developers of knowledge bases. Design An observational study in which investigators visited physicians for two half-days and collected their questions. Taxonomies were developed to characterize the clinical topic and generic type of information sought for each question. Setting Eastern Iowa. Participants Random sample of 103 family physicians. Main outcome measures Number of questions posed, pursued, and answered; topic and generic type of information sought for each question; time spent pursuing answers; and information resources used. Results Participants asked a total of 1,101 questions. Questions about drug prescribing, obstetrics and gynecology, and adult infectious disease were most common, comprising 36% of the total. The taxonomy of generic questions included 69 categories; the three most common types, comprising 24% of all questions, were "What is the cause of symptom X?" "What is the dose of drug X?" and "How should I manage disease or finding X?" Answers to most questions (n = 702 [64%]) were not immediately pursued, but of those pursued, most (n = 318 [80%]) were answered. Physicians spent an average of less than 2 minutes pursuing an answer, and they used readily available print and human resources. Only two questions led to a formal literature search. Conclusions Family physicians in this study did not pursue answers to most of their questions. Questions about patient care can be organized into a limited number of generic types, which could help guide the efforts of knowledge-base developers.

Primary care physician perceptions of the nurse practitioner in the 1990s.

OBJECTIVE: To evaluate factors associated with primary care physician attitudes toward nurse practitioners (NPs) providing primary care. DESIGN: A mailed survey of primary care physicians in Iowa. SETTING AND PARTICIPANTS: Half (N = 616) of the non-institutional-based, full-time, primary care physicians in Iowa in spring 1994. Although 360 (58.4%) responded, only physicians with complete data on all items in the model were used in these analyses (n = 259 [42.0%]). MAIN OUTCOME MEASURES: There were 2 principal dependent measures: physician attitudes toward NPs providing primary care (an 11-item instrument) and physician experience with NPs in this role. Bivariate relationships between physician demographic and practice characteristics were evaluated by chi 2 tests, as were both dependent variables. Ordinary least-squares regression was used to determine factors related to physician attitudes toward NPs. RESULTS: In bivariate analyses, physicians were significantly more likely to have had experience with an NP providing primary care if they were in pediatrics or obstetrics-gynecology (78.3% and 70.0%, respectively; P < .001), had been in practice for fewer than 20 years (P = .045), or were in practices with 5 or more physicians. The ordinary least-squares regression indicated that physicians with previous experience working with NPs providing primary care (P = .01), physicians practicing in urban areas with populations greater than 20,000 but far from a metropolitan area (P = .03), and general practice physicians (P = .04) had significantly more favorable attitudes toward NPs than did other primary care physicians. CONCLUSIONS: The association between previous experience with a primary care NP and a more positive attitude toward NPs has important implications for the training of primary care physicians, particularly in community-based, multidisciplinary settings.

What clinical information resources are available in family physicians' offices?

BACKGROUND: When faced with questions about patient care, family physicians usually turn to books in their personal libraries for the answers. The resources in these libraries have not been adequately characterized. METHODS: We recorded the titles of all medical books in the personal libraries of 103 randomly selected family physicians in eastern Iowa. We also noted all clinical information that was posted on walls, bulletin boards, refrigerators, and so forth. Participants were asked to describe their use of other resources such as computers, MEDLINE, reprint files, and "peripheral brains" (personal notebooks of clinical information). For each physician, we recorded how often the resources were used to answer clinical questions during 2 half-day observation periods. RESULTS: The 103 participants owned a total of 5794 medical books, with 2836 different titles. Each physician kept an average of 56 books in the office. Prescribing references (especially the Physicians' Desk Reference) were most common (owned by 100% of the participants), followed by books on general internal medicine (99%), adult infectious disease (89%), and general pediatrics (83%). Books used to answer clinical questions were more likely to be up to date (copyright date within 5 years) than unused books (74% vs 27%, P <.001). Items posted on walls included drug dosage charts and pediatric immunization schedules. Only 26% of the physicians had computers in their offices. CONCLUSIONS: Drug-prescribing textbooks were the most common type of book in family physicians' offices, followed by books on general internal medicine and adult infectious diseases. Although many books were relatively old, those used to answer clinical questions were generally current.

Is paracervical block safe and effective? A prospective study of its association with neonatal umbilical artery pH values.

BACKGROUND: Paracervical blocks (PCBs) relieve labor pain, but reports of associated complications have caused many physicians to question their safety. METHODS: We designed a prospective observational study to examine the association between PCBs and umbilical artery hydrogen ion concentration (pH) values. A total of 261 healthy women in labor were recruited from a community hospital. Physicians used 1% lidocaine for the PCBs. We used multivariate linear regression to model predictors of umbilical artery pH at birth. RESULTS: Of the women studied, 238 (91%) received analgesia during labor (nalbuphine, PCB, pudendal, caudal, or epidural). Of these, 126 (48%) received at least one PCB (191 were given), and 197 (76%) received at least one dose of nalbuphine (237 were given). Univariate analyses showed no significant differences in mean 1-minute Apgar scores, 5-minute Apgar scores, umbilical artery pH, resuscitation with oxygen by mask, or length of newborn stay according to either PCB or nalbuphine exposure. Factors significantly associated with lower umbilical artery pH in a linear regression analysis included longer second stage of labor (-0.032 pH units for each 1-hour increase; 95% confidence interval [CI], -.046 to -.018), pudendal block (-0.022; 95% CI, -.040 to -.004), intrauterine pressure catheter use (-0.029; 95% CI, -0.053 to -.006), nuchal cord (-0.027; 95% CI, -.051 to -.004), and midforceps delivery (-0.080; 95% CI, -.159 to .000). Increasing maternal age and induction with either artificial rupture of membranes or gel were associated with higher umbilical artery pH values. CONCLUSIONS: After adjusting for other variables, neither PCB nor nalbuphine use were associated with umbilical artery pH at birth. PCBs using 1% lidocaine injected superficially should be considered a safe and effective form of obstetric analgesia. PCBs may be especially useful for women giving birth in hospitals where other obstetric anesthesia services are not readily available.

Predictors of neonatal resuscitation, low Apgar scores, and umbilical artery pH among growth-restricted neonates.

OBJECTIVE: To identify risk factors associated with poorer immediate neonatal outcomes among growth-restricted neonates. METHODS: Records of all 530 growth-restricted neonates born between January 1989 and February 1995 were reviewed. Outcomes included resuscitation measures, Apgar scores, and umbilical blood gas values. Neonates were assigned to one of six anesthetic groups, and outcomes were compared. Predictors of poorer outcomes were examined using logistic and linear regression. RESULTS: Neonates exposed to general anesthesia were more likely to be intubated (37.9% versus 4.1%, P < .001, Pearson chi2) and had lower mean 1- (4.0 versus 7.0) and 5-minute (6.5 versus 8.4) Apgar scores (P < .01, Scheffé) than those in all other anesthetic groups. They also had significantly lower umbilical artery (UA) pH values than neonates who received nalbuphine, epidural, or no anesthesia (7.21 versus 7.28, 7.26, 7.29, respectively; P < .01, Scheffé). Factors that significantly and independently predicted intubation among all neonates included exposure to general anesthesia (odds ratio [OR] 4.1; 95% confidence interval [CI] 1.9, 8.9) and lower infant weight (OR 10.1 per kg decrease; CI 5.1, 20). Factors predicting UA pH at most 7.15 included preeclampsia (OR 3.0; CI 1.5, 5.9) and older maternal age (OR 1.3 per 5 years; CI 1.02, 1.64); vertex delivery (OR 0.5; CI 0.2, 0.9) was protective. Factors predicting a 5-minute Apgar less than 7 were meconium (OR 1.5 per category going from none to terminal to light to heavy; CI 1.04, 2.3), general anesthesia (OR 6.9; CI 2.6, 18.2), lower infant weight (OR 16.5 per kg decrease; CI 7.8, 34.5), and vaginal breech delivery (OR 7.0; CI 1.8, 28.6); cesarean delivery (OR 0.2; CI 0.08, 0.66) was protective. Spontaneous vertex delivery raised the UA pH, and preeclampsia, amnioinfusion, breech delivery, and general anesthesia significantly and independently lowered the UA pH among all neonates. For infants delivered by cesarean, "fetal distress," preeclampsia, previous spontaneous abortion, failed forceps use, and nalbuphine significantly and independently predicted lower UA pH. CONCLUSION: Risk factors for poorer immediate neonatal outcomes among growth-restricted neonates include preeclampsia, fetal distress, breech delivery, forceps use, nalbuphine during labor, lower infant weight, and general anesthesia.

Unique learning contributions of a family medicine preceptorship.

BACKGROUND: There is a belief among family medicine educators that a third-year family medicine rotation provides unique clinical learning experiences, but there is limited research to support this belief. This study identified clinical skills performed by third-year medical students only during a community-based family medicine preceptorship, even when the family medicine rotation occurs after all other required clerkships. METHODS: During 6 academic years (1990-1996), 87 third-year students completed the family medicine preceptorship as their final rotation and rated their experience with 80 clinical activities (preventive health care, clinical problem management, and procedures) after completing all required clerkships other than family medicine and again after the family medicine preceptorship. Ratings measured whether the activities occurred on the family medicine rotation, only on other rotations, or combinations of both. RESULTS: More than 50% of students who performed five preventive skills (health maintenance for adolescents, young adults, middle-aged adults, or senior citizens and weight control counseling) gained that experience only during the family medicine preceptorship. The majority of students actively managed six clinical problems (acute strains and sprains, low back pain, sinusitis, strep throat, acute bronchitis, and osteoarthritis) uniquely during the family medicine preceptorship. The preceptorship offered few unique opportunities to perform procedures. CONCLUSIONS: This family medicine educational experience was not merely a repeat of what is experienced on the traditional major rotations. The family medicine preceptorship provided a setting where students were able to perform several important ambulatory, primary care skills they had not performed during their core curriculum of traditional third-year rotations.

Clinical diagnosis and the order of information.

BACKGROUND: Information order can influence judgment. However, it remains unclear whether the order of clinical data affects physicians' interpretations of these data when they are engaged in familiar diagnostic tasks. METHODS: Of 400 randomly selected family physicians who were given a questionnaire involving a brief written scenario about a young woman with acute dysuria, 315 (79%) returned usable responses. The physicians had been randomized into two groups, and both groups had received the same clinical information but in different orders. After learning the patient's chief complaint, physicians received either the patient's history and physical examination results followed by the laboratory data (the H&P-first group) or the laboratory data followed by the history and physical examination results (the H&P-last group). The results of the history and physical examination were supportive of the diagnosis of UTI, while the laboratory data were not. All physicians judged the probability of a urinary tract infection (UTI) after each piece of information. RESULTS: The two groups had similar mean estimates of the probability of a UTI after learning the chief complaint (67.4% vs 67.8%, p = 0.85). At the end of the scenario, the H&P-first group judged UTI to be less likely than did the H&P-last group (50.9% vs 59.1%, p = 0.03) despite having identical information. Comparison of the mean likelihood ratios attributed to the clinical information showed that the H&P-first group gave less weight to the history and physical than did the H&P-last group (p = 0.04). CONCLUSIONS: The order in which clinical information was presented influenced physicians' estimates of the probability of disease. The clinical history and physical examination were given more weight by physicians who received this information last.

Skills that Iowa family physicians desire in a new physician partner.

BACKGROUND AND OBJECTIVES: The importance of specific skills in primary care continues to be debated. As a result, there is not consensus on which skills need to be stressed during residency training. Our project asked community-based family physicians to rate the importance of specific skills in a new family physician partner. METHODS: Data were collected through a cross-sectional survey of all active members of the Iowa Academy of Family Physicians. Participants were surveyed by mail, using a list of 83 skills pertinent to primary care. Physicians were asked to rate the importance of a new member of their practice having the individual skills on this list. RESULTS: A total of 546 family physicians (67%) completed questionnaires. Fourteen skills (seven cognitive and seven psychomotor) were reported to be "essential" or "very important" by at least 80% of the physicians. A total of 43 skills were rated as "essential" or "very important" by at least 50% of responding family physicians. Many of the hospital-based procedural skills, particularly those used in an intensive care setting, were rated as less important. The importance ratings of many skills were associated with the physicians' ages, size of their primary hospitals, and availability of other medical specialties. CONCLUSIONS: Family physicians tended to rate office-based procedural skills, counseling skills, and management skills as "essential or very important" to their practices. These rating might be used to guide residency training in family practice.
