Practice variations between family physicians and obstetricians in the management of low-risk pregnancies.

BACKGROUND: Studies suggest that family physicians and other generalist physicians practice differently than specialists. This study was performed to determine whether practice patterns and outcomes differ for women with low-risk pregnancies who obtain maternity care from family physicians as compared with those who are cared for by obstetricians. METHODS: A retrospective chart review was performed at five sites across the United States. Women who presented for elective repeat cesarean section or who had any one of 14 high-risk conditions were excluded from the analysis. The final sample analyzed included 4865 women. Family physicians managed the labor of 2000 of these women, and obstetricians managed 2865. RESULTS: During intrapartum care, women managed by family physicians were less likely to have their labor induced (8.6% vs 10.4%, P = .03), receive oxytocin augmentation (14.9% vs 17.8%, P = .006), or receive epidural anesthesia (5.4% vs 17.0%, P < .001) as compared with those managed by obstetricians. Delivery outcomes showed that patients of family physicians were less likely to have an episiotomy during vaginal delivery (53.7% vs 74.5%, P < .001) and a lower frequency of cesarean section deliveries (9.3% vs 16.0%, P < .001), especially for cephalopelvic disproportion. When adjusted for potential confounders, rates for cesarean section and episiotomy for obstetricians were still significantly higher than those of family physicians. For neonatal outcomes (low 1-minute Apgar score, neonatal intensive care unit admission, birth trauma, or neonatal infection), no significant differences were found between the care delivered by obstetricians and family physicians. CONCLUSIONS: Women obtaining maternity care from family physicians were less likely to receive epidural anesthesia during labor or an episiotomy after vaginal births, and had a lower rate of cesarean section delivery rates, primarily because of a decreased frequency in the diagnosis of cephalopelvic disproportion. Differences between outcomes persisted after adjustment for potential confounders such as parity, previous cesarean delivery, and use of epidural anesthesia during labor. No differences between the two physician groups with respect to neonatal outcomes were found.

Experiences and attitudes about faith healing among family physicians.

BACKGROUND: Recent media attention has focused on patients who use faith healers to care for their medical problems. Many people who use faith healers also consult physicians. This study was done to learn more about how often physicians see patients who are involved in faith healing, and to learn more about physicians' attitudes about, and experiences with, faith healing. METHODS: A 1-page questionnaire was mailed to 1025 family physicians in seven states; 594 participated, for a response rate of 59%. RESULTS: Approximately one half (52%) of the physicians were aware of at least one patient in their practice who had had a faith-healing experience. Most physicians came in contact with such patients no more frequently than once a year. Fifty-five percent agreed and 20% disagreed that reliance on faith healers often leads to serious medical problems. However, 44% thought that physicians and faith healers can work together to cure some patients, and 23% believed that faith healers divinely heal some people whom physicians cannot help. CONCLUSIONS: These results suggest that family physicians are infrequently aware of faith-healing beliefs and experiences among their patients. Family physicians were divided in their views about faith healing, with a majority expressing skepticism about faith healing and a sizeable minority favorable toward it.

Diagnosis of illness presentation in the elderly.

In the standard medical model of diagnosis, there is a 1:1 correspondence between clinical symptoms and signs and a pathological disease process. However, it is believed that this model does not accurately define many illness presentations in elderly patients. The frequency with which the medical model is diagnostically accurate, and the other models that might more effectively diagnose geriatric illness, are unknown. This study was designed to ascertain the frequency with which the medical model of diagnosis pertains in a clinical population of older adults and to develop and validate alternative models for diagnosis of illness presentation in this population. Using a retrospective chart review (n = 86) and a prospective validation in a second sample (n = 56) of geriatric assessment clinic patients, it was found that the medical model of illness fit less than half of the patients. To describe the illness presentations of the remaining patients, four new diagnostic models of illness presentation were identified which incorporate comorbidity, functional, and psychosocial factors. Use of these new models along with the medical model of illness diagnosis may assist in more accurate and complete diagnosis in elderly patients and enhance teaching of effective diagnosis in geriatric medicine.

Family practice patients' experiences and beliefs in faith healing.

Faith healers have become more visible as an alternative to traditional medicine because of the growth of television evangelism. The extent to which patients engage in alternative therapies such as faith healing, however, is not fully known. To further explore patients' involvement in faith healing, a cross-sectional survey was administered to 207 patients in one rural family practice. Most respondents (58 percent) reported that faith healers are "quacks," but 29 percent believed that faith healers can help some people who physicians cannot help. Twenty-one percent had attended a faith-healing service. Six percent stated they had actually been healed by faith healers, and 15 percent reported they personally knew someone who had been healed. Participation in faith-healing services was significantly higher among blacks (P less than .01) and those with less than a high school education (P less than .01). The finding that many patients embrace faith healing has implications for traditional family practice and may explain why patients sometimes reject medical treatment. Physicians need to be sensitive to patients' beliefs about "faith," and must determine the extent to which patients reject the scientific approach before physicians can become effective "healers."

Estimating fetal age using multiple parameters: a prospective evaluation in a racially mixed population.

This study was designed to evaluate the accuracy of regression models for menstrual age prediction using single versus multiple fetal ultrasonographic measurements (biparietal diameter, head circumference, abdominal circumference, and femur length). The models tested had been previously developed from a study of middle-class white patients in a private hospital. The current study population consisted of 300 indigent black and Hispanic patients seen in a county hospital. This study demonstrated prospectively that the use of multiple parameters in estimating fetal age offers a significant advantage over any single parameter used alone and that the regression equations developed from a middle-class white population appear to be applicable to fetuses from a population with different socioeconomic and racial characteristics.

Prescribing postpartum iron supplementation: a survey of practicing obstetricians.

Supplemental iron (excluding the amount in prenatal vitamins) is routinely recommended post partum by standard obstetric textbooks. We surveyed practicing obstetricians in Maryland to examine their indications for and prescription of postpartum iron supplements. The survey was returned by 201 physicians (33% response rate). Iron was prescribed by 25% of the physicians always, 12% never, and 63% depending upon the patient. An average of 37% of postpartum patients were given iron. The most frequently cited indication for prescribing iron was the postpartum hematocrit level (used by 90% of the physicians), followed by high blood loss (41%), operative delivery (15%), mean corpuscular volume (12%), and toxemia (9%). The postpartum iron dosage (325 mg) was prescribed as a single daily dose by 22%, twice daily by 37%, and three times daily by 32%. These practices do not correspond to the current recommendation that postpartum iron should always be prescribed.

Treatment of mild to moderate pain of acute soft tissue injury: diflunisal vs acetaminophen with codeine.

Acute soft tissue injuries create pain and limitation of function. Treatment requires analgesia and time for full recovery. Acetaminophen with codeine (650 mg plus 60 mg, respectively, every 4 to 6 hours) is used frequently as the analgesic of choice. Diflunisal (1,000 mg initially then 500 mg twice a day) vs acetaminophen with codeine was prospectively studied in the treatment of acute mild to moderate pain from soft tissue injuries. Thirty-five patients with acute strains, sprains, or low back pain were randomized to treatment (17 acetaminophen with codeine vs 18 diflunisal). Both groups were similar in the amount of pain and type of injury at initiation of therapy. Patient pain rating went from 3.3 +/- 0.6 to 1.6 +/- 1.5 for acetaminophen with codeine and from 3.3 +/- 0.6 to 1.3 +/- 1.1 for diflunisal. However, 65 percent of acetaminophen with codeine patients experienced side effects, with 35 percent of these patients stopping the medication because of intolerable side effects. In the diflunisal group, 28 percent of the patients experienced side effects and 5 percent had to stop the medication early. Diflunisal was found to be an effective analgesic in mild to moderate pain of acute soft tissue injuries, and caused fewer and more tolerable side effects than did acetaminophen with codeine.

Thin-layer chromatographic analysis of cocaine and benzoylecgonine in urine.

The sensitivity achieved by the described thin-layer chromatographic (TLC) method greatly exceeds that of previously published TLC methods for the determination of cocaine and its principal metabolite, benzoylecgonine, in urine. Sensitivity for cocaine and benzoylecgonine approaches 0.1 and 0.25 mug/ml, respectively, for a 5.0-ml specimen. A simple extraction with a mixed organic solvent provides the basic mechanism for isolating the drugs from biologic specimens. Cocaine and its metabolites are stable in sulfuric acid solutions but labile in aqueous media containing certain other inorganic and organic acids; therefore, an emphasis on the utilization of sulfuric acid solutions is employed throughout the procedure. An evaluation of sensitivities achieved for cocaine and benzoylecgonine by various detection reagents is presented. The technique is applicable to drug screening programs.
