Insurance or a regular physician: which is the most powerful predictor of health care?

OBJECTIVES: This study compared the relative effects on access to health care of relationship with a regular physician and insurance status. METHODS: The subjects were 1952 nonretired, non-Medicare patients aged 18 to 64 years who presented with 1 of 6 chief complaints to 5 academic hospital emergency departments in Boston and Cambridge, Mass, during a 1-month study period in 1995. Access to care was evaluated by 3 measures: delay in seeking care for the current complaint, no physician visit in the previous year, and no emergency department visit in the previous year. RESULTS: After clinical and socioeconomic characteristics were controlled, lacking a regular physician was a stronger, more consistent predictor than insurance status of delay in seeking care (odds ratio [OR] = 1.6, 95% confidence interval [CI] = 1.2, 2.1), no physician visit [OR] = 4.5%, 95% CI = 3.3, 6.1), and no emergency department visit (OR = 1.8, 95% CI = 1.4, 2.4). For patients with a regular physician, access was no different between the uninsured and the privately insured. For privately insured patients, those with no regular physician had worse access than those with a regular physician. CONCLUSIONS: Among patients presenting to emergency departments, relationship with a regular physician is a stronger predictor than insurance status of access to care.

Changes in the 1995 Current Population Survey and estimates of health insurance coverage.

This analysis compares the March 1994 and March 1995 Current Population Survey (CPS) counts of the numbers of people with different types of health insurance and without any health insurance coverage. The findings contain some surprises: there were no changes in the numbers of nonelderly people with Medicaid coverage and without any health insurance, and there were increases in the numbers of nonelderly people with employer-sponsored health insurance and with CHAMPUS/VA/military health care. Four changes were introduced in the CPS in 1995 and were likely, by themselves, to both raise and lower the estimates of the numbers of people with specific types of health insurance coverage. Three of the changes relate to questions about health insurance coverage; they coincide with the traditional mid-decade shift in the sample framework for the CPS.

Integrated health care, capitated payment, and quality: the role of regulation.

Concerns about the effect of managed care techniques on the quality of medical care have been raised in many quarters. Physicians have advocated the reiteration of professional ethics or even the prohibition of market incentives in health care as solutions to the problem of cost-quality tradeoffs in managed care systems. However, few recognize the existing systems for the regulation of managed care or consider how additional regulation could alleviate some of the potential problems posed by market-based competition. We review the evolution and growth of managed care organizations and the payment techniques that could cause a conflict between patient welfare and physician income. We then discuss the existing types of federal and state regulation of managed care and suggest some new incentives that could buttress the ethical practice of medicine in the medical marketplace.

Transvaginal embryo transfer during the zygote intrafallopian tube transfer procedure.

OBJECTIVE: Our purpose was to evaluate a tactile non-ultrasonographically directed approach to transvaginal tubal cannulation and embryo transfer during the zygote intrafallopian tube transfer procedure. STUDY DESIGN: We studied the application of the tactile approach to transvaginal tubal cannulation and embryo transfer in 68 consecutive zygote intrafallopian tube transfer cycles. RESULTS: The tactile approach to transvaginal tubal cannulation and subsequent embryo transfer was successful in 93% of couples. Pregnancy occurred in 16 of the 63 (25%) women undergoing a successful transvaginal embryo transfer. CONCLUSION: The tactile approach to transvaginal tubal cannulation was found to be easily learned and provided a safe and convenient method of tubal embryo transfer. This low-cost approach, which has application to transfer of both embryos and gametes, deserves further study.

Personal characteristics and spells without health insurance.

People without health insurance differ not only in their personal characteristics and reasons for being without health insurance but also in the length of time they spend in uninsured spells. A hazard model of spell durations is used to estimate the relative effects of a person's characteristics in the month just before an uninsured spell begins on the duration of the spell. Using the Survey of Income and Program Participation, our analyses indicate that monthly family income, educational attainment, and industry of employment in the month prior to losing health insurance are the characteristics that have the greatest impact on the exit rate from being without health insurance. Because low-income people could end an uninsured spell with either private health insurance or Medicaid, findings from an exploratory competing risks model are also reported.

Spells without health insurance: the distribution of durations when left-censored spells are included.

In a previous paper (1990), we estimated the distribution of durations of uninsured spells for which the beginning could be observed. We raised the concern that uninsured spells that were in progress when the Survey of Income and Program Participation began might not be proportionally represented in a sample of uninsured spells restricted to spells with observed beginnings. This paper includes spells in progress when SIPP began. Including left-censored spells, and correcting for length bias inherent in such spells, does not fundamentally change our previous estimate of the distribution.

Open versus laparoscopic cholecystectomy: an initial analysis.

Laparoscopic cholecystectomy is a new procedure in the armamentarium of the general surgeon. Its utility was investigated by comparison to open cholecystectomy in terms of procedure time, complications, hospital stay, and total hospital cost. Procedure time was approximately 200% longer with a higher incidence of intraoperative stone and bile spillage (17%) in the laparoscopic group. Hospital stay was reduced by 60% using the laparoscopic technique. No difference in total hospital cost existed between the two groups. The learning curve had an affect on hospital costs, which will decrease as more experience is gained with this procedure. Although laparoscopic cholecystectomy, at least initially, has no cost advantage over open cholecystectomy, laparoscopic cholecystectomy may be preferred by patients seeking shorter hospital stays and presumably shorter total recovery time.

Why requiring employers to provide health insurance is a bad idea.

There is mounting pressure at the federal (and state) level to require employers to provide health insurance to their employees. However, two quite different groups of workers could be affected by such a mandate. In addition, there are at least five major problems with requiring employers to provide health insurance. Chief among these is the further fracturing of the insurance market, so that the spreading of risk will be reduced, and only the young and healthy will be offered insurance at relatively low premiums. We should be designing a health insurance system that has both universal coverage and a cost-containment structure. Toward this end, we need to tackle issues that transcend alternative methods of financing health care in the U.S.
