Changes in health plans serving Medicaid, 1993-1996

To better understand the Medicaid managed care market during a period of rapid change, we developed a new data set that links Medicaid enrollment data with health maintenance organization (HMO) industry data for 1993-1996 to analyze Medicaid enrollment in full-risk health plans. Nearly half of the Medicaid enrollees in a fully capitated managed care arrangement were in plans in which Medicaid makes up at least 75 percent of the total enrollment. In addition, the number of Medicaid-only plans has more than doubled since 1993. Commercial-based plans participated increasingly in Medicaid managed care during the period, yet more than half of the plans entering the Medicaid market were newly formed.     

Educational programs in US medical schools, 1996-1997

We use data from the 1996-1997 Liaison Committee on Medical Education Annual Medical School Questionnaire, which had a 100% response rate, to describe medical education programs in the United States. In the 1996-1997 academic year, there were 95 568 full-time medical school faculty members, a 4.5% increase from 1995-1996. In clinical departments, the largest increases were in emergency medicine (a 29% increase from 1995-1996) and family medicine (a 13% increase). Of all full-time faculty members in clinical departments, 76.9% have an MD or DO as the highest degree, 4.5% have both an MD and PhD, 13.9% have a PhD, and 4.7% have an academic or professional bachelor's or master's degree as their final degree. The total number of applicants for the class entering in 1996 was 46968 (0.8% increase from 1995), while the number of first-time applicants decreased 1% from 1995. First-year medical students who were members of underrepresented minority groups numbered 2236, a 4% decrease from 1995. In 1996-1997, the total number of medical students was 66712 (0.3% less than in 1995-1996). For students graduating during the 1995-1996 academic year, 13% took longer than 4 years to complete the program. There were 47 medical schools that reported that 1 or more hospitals used for required clinical clerkships had changed ownership, merged, or closed during 1996. Medical schools used an average of 6 (range, 1-36) hospitals for core clinical clerkship. Ninety-five schools required a passing grade on Step 1 of the US Medical Licensing Examination (USMLE) for promotion or graduation; 54 schools required a passing grade on Step 2 of the USMLE.     

Epidemiology of congenital diaphragmatic hernia, Hawaii, 1987-1996

Congenital diaphragmatic hernias (CDHs) in Hawaii between 1987 and 1996 were examined with data from a birth defects surveillance system. There were 51 cases of CDH (prevalence 2.45 per 10,000 births). Forty-nine percent of livebirths survived, an increase over the rate reported in Hawaii in 1975-1982. These results are similar to those reported by other population-based studies.     

Review of US medical school finances, 1995-1996

We discussed the rational extent of the lymph node dissection for carcinoma of the lower third of the esophagus of T2 or T3 stage with abdominal lymph node metastasis. Lymph node metastasis developed in 89.5% of patients. Cervical lymph node metastasis was seen in 35.8%. In the cases with positive abdominal lymph node, 40.9% of the patients had cervical node metastasis. The most frequent site of the positive node in the neck is the area along the right recurrent laryngeal nerve. On the stand point of removal of metastatic lymph node, neck dissection should be required. Three-field dissection yielded better survival rate than two-field dissection but statistical significance was not obtained. When the patients have cervical lymph node metastasis, they have greater possibility of developing blood borne metastasis. However, this observation does not deny the validity of the three-field dissection. Because this dissection may help reducing nodal spread and nodal recurrence. We have to wait for accumulation of the patients to analyze the definite extent of node dissection for T2 or T3 stage of carcinoma of the lower third of the esophagus with positive abdominal lymph node.     

A summary of the 1996-1997 Canadian FluWatch program

We studied systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse frequency (P.F) and mean blood pressure (MBP) among 30 pregnant women in 39.5 +/- 0.3 gestational weeks of pregnancy, age 23 +/- 0.9 years, height 162.0 +/- 1.4 cm and weight 75.5 +/- 2.55 kg. The above indices were studied dynamically in the Ist, 2nd, 3rd, 5th, 7th, 9th, 12th and 15th minute from the onset of the analgesia. We founded that SBP an DBP in the 7th min (the time for spinal block) were lowest. PF and MBP also decreased significantly in the 7th minute in comparison to the inmal values. We can conclude that the haemodynamic indices of the pregnant woman decrease wrong initiation of spinal analgesia for c.s., but remain in the region of normal reference values.     

Education programs in US medical schools, 1995-1996

We present herein data on US medical education programs and describe how medical schools are adapting to a changing health care environment. The data mainly derive from the 1995-1996 Liaison Committee on Medical Education Medical School Questionnaire, which had a 100% response rate. The data indicate that in the 1995-1996 academic year there were 91 451 full-time faculty members in basic science and clinical departments, a 1.6% increase from 1994-1995. In clinical departments, major increases occurred in emergency medicine (a 10.6% increase in full-time faculty) and family medicine (a 13.5% increase). Applicants for the class entering in 1995 numbered 46 591, an increase of 2.7% from 1994; however, the number of first-time applicants decreased slightly (0.6%). Of the 17 357 applicants accepted, 2179 (12.6%) were members of underrepresented minority groups. Health system changes are affecting medical school clinical affiliations. During the past 2 years, 42 schools saw a merger, acquisition, or closure involving medical school-owned or medical school-affiliated hospitals used for core clinical clerkships. At 15 sites, this change affected the distribution of students across clinical sites. In 1995-1996, 40 medical schools or their universities owned a health maintenance organization or other managed care organization, 93 schools contracted with a managed care organization to provide primary care services, and 96 schools contracted with managed care to provide specialty services. During the past year, 57 schools acquired primary care physician practices, and 70 started primary care clinics in the community.     

Entry of US medical school graduates into family practice residencies: 1996-1997 and 3-year summary

BACKGROUND AND OBJECTIVES: This is the 16 report prepared by the American Academy of Family Physicians (AAFP) on the percentage of each US medical school's graduates entering family practice residency programs. Approximately 15.9% of the 16,029 graduates of the US medical schools between July 1995 and June 1996 were first-year family practice residents in October 1996, compared with 14.6% in 1995 and 13.4% in 1994. This is the highest percentage since 1980-1981 (12.8%), when this series of studies began. Medical school graduates from publicly funded medical schools were almost twice as likely to be first-year family practice residents in October 1996 than were residents from privately funded schools, 19.1% compared with 11.2%. The Mountain region reported the highest percentage of medical school graduates who were first-year residents in family practice programs in October 1996 at 24%; the Middle Atlantic and New England regions reported the lowest percentage at 11.4% and 9.9%, respectively. Nearly half of the medical school graduates (48.4%) entering a family practice residency program as first-year residents in October 1996 entered a program in the same state where they graduated from medical school. The percentages for each medical school have varied substantially from year to year since the AAFP began reporting this information. This article reports the average percentage for each medical school for the last 3 years. Also reported are the number and percentage of graduates from colleges of osteopathic medicine who entered Accreditation Council for Graduate Medical Education-accredited family practice residency programs.     

Educational programs in US medical schools, 1997-1998

To describe the current status of medical education programs in the United States, we used data from the 1997-1998 Liaison Committee on Medical Education Annual Medical School Questionnaire, which had a 100% response rate, and from other sources. There were 96733 full-time medical school faculty members, a 1.2% increase from 1996-1997. The 43020 applicants for the class entering in 1997 represents an 8.4% decrease from 1996. The number of 1997 applicants who were members of underrepresented minority groups decreased 11.1 % from 1996, and the number of entering underrepresented minority group students decreased 8.4%. More than half of medical schools reported that the number of inpatients available for medical student education had decreased in at least some of their clinical sites or in some disciplines during the past 2 years. Thirty-nine medical schools (31.2%) reported having more difficulty recruiting or retaining volunteer clinical faculty to participate in medical student teaching in 1997 than in 1995.     

Macrolide susceptibility and beta-lactamase production among haemophilus influenzae isolates in the United States, 1996-1997

In 1996 and 1997, 68 hospital laboratories throughout the United States determined the beta-lactamase production and susceptibility to macrolides of 1,998 isolates of Haemophilus influenzae obtained from patients with community-acquired respiratory tract infections. The MICs at which 90% of the isolates are inhibited of azithromycin, erythromycin, and clarithromycin were 4, 8, and 16 microgram/ml, respectively. By National Committee for Clinical Laboratory Standards interpretive criteria, 99 and 78% of the isolates were susceptible to azithromycin and clarithromycin, respectively. The prevalence of beta-lactamase production was 32%.     

The role of sodium bisulfite in the 1996-1997 USA influenza vaccine recall

During the 1996-1997 influenza season, all the lots of influenza vaccine manufactured by Parke-Davis were recalled. This voluntary recall by the manufacturer was prompted by the finding of decreasing potency of the A/Nanchang/933/95 (H3N2) component of the vaccine. The primary cause of this lowered potency has been identified as primarily due to the presence of sodium bisulfite which was used to neutralize residual formaldehyde which in turn is used to inactivate the live influenza vaccine strains. This paper reviews these events and what we have learned.     

Correlates of gonococcal infection and of antimicrobial-resistant Neisseria gonorrhoeae among female sex workers, Republic of the Philippines, 1996-1997

From 1994 to 1997, the proportion of Neisseria gonorrhoeae highly resistant to ciprofloxacin (MIC >/=4 microg/mL) increased substantially among female sex workers (FSWs) in the Philippines. Among 1499 Filipina FSWs, we evaluated factors associated with gonococcal infection and with gonococcal antimicrobial resistance. By multivariate analysis, gonococcal infection was associated with sex with a new client, self-prescribed prophylactic antimicrobial use, work in a brothel, and inconsistent condom use and was negatively associated with registration status and vaginal hygiene practices. Factors associated with ciprofloxacin-resistant gonococci included: marital status, living alone, duration of sex work, and clinic site. Further, gonococci highly resistant to ciprofloxacin were isolated from 10 (11.5%) of 87 FSWs reporting self-prescribed antimicrobial use versus 44 (3.4%) of 1295 reporting no antimicrobial use (P<.001). Self-prescribed prophylactic antimicrobial use and inconsistent condom use could be important factors in the continued emergence of gonococcal antimicrobial resistance in the Philippines.     

Effect of an influenza vaccination campaign in the municipality of Copenhagen during the 1996-1997 season

In Denmark influenza vaccinations are usually paid for by the patients. In the autumn of 1996 Copenhagen City Council offered free influenza vaccinations to all residents aged 70 years or older. The impact of the campaign was evaluated in a questionnaire study of a random sample of the Danish population aged 70 years or older. In Copenhagen 81% (95% Confidence interval: 67-95%) of the elderly at risk were vaccinated compared to 51% (45-56%) outside Copenhagen. Offering free influenza vaccinations in a mass campaign is an effective way of improving coverage rate. However, no substantial difference was found in cost between the mass campaign and a targeted campaign with free vaccination in general practice.     

Comparison of influenza immunization rates for Oklahoma Medicare patients: 1995, 1996 and 1997

The Health Care Financing Administration has reported influenza immunization rates since 1994. The Department of Health and Human Services has set a minimum national target rate for the annual immunization of the elderly population at 60 percent, as published in Healthy People 2000. The Oklahoma Foundation for Medical Quality analyzed the Medicare claims data for Oklahoma for the 1995, 1996, and 1997 influenza seasons. Additionally, we reviewed the Behavioral Risk Factor Surveillance System influenza immunization data for 1995. Claims data for the 1997 influenza season show the immunization rate for the Medicare population of Oklahoma is 41.4 percent. The immunization rate for the African-American Medicare population was 22.3 percent for 1997, compared with 42.2 percent for the Caucasian population. The ten most populous counties in the state had a 9-percent higher rate of immunization than the other 67 counties. The Medicare population in Oklahoma is not receiving the influenza vaccination at the target rate. Especially underserved are the African-American and non-urban populations. There appear to be opportunities for improvement in the provision of the influenza vaccination for the Medicare population of Oklahoma.
