Continuity and change in preferred provider organizations.

This paper presents the results from a national survey of preferred provider organizations (PPOs) that was conducted in 1988. It is based on telephone interviews conducted by the authors with executives in over 170 PPOs in the United States. We compare the survey results with those obtained from similar surveys conducted in 1985 and 1986, allowing us to assess the extent to which PPOs have grown and changed. We found that PPOs have continued to grow at an extremely rapid rate. During the Summer and Fall of 1988, the time in which the survey took place, 37.6 million people were eligible to use PPO benefits, compared to the 16.5 million figure we obtained two years earlier. We did not find, however, that PPOs are moving in the direction of providing more innovative forms of health care cost containment. Most PPOs still rely on discounts from providers and utilization review to achieve savings. There is little trend towards using incentive reimbursement techniques and choosing preferred providers that have shown themselves to be cost-efficient. We conclude that in the coming years PPOs must demonstrate the ability to control rising health care costs. To accomplish this, they will need to put more pressure on providers to use resources more sparingly. Otherwise, they may lose their market share to other forms of managed care.

Changes in retiree health benefits: results of a national survey.

Employers are increasingly concerned by the cost of health benefits provided to retired workers. One reason is that the Financial Accounting Standards Board (FASB), the organization that establishes "generally accepted accounting principles," has proposed altering the way firms report expenditures for retiree medical coverage on financial statements. We recently completed a national survey of business firms offering retiree health benefits to address three issues: 1) What is the current structure of retiree health benefit plans? 2) What changes are firms planning to implement in the structure of their retiree health benefits? 3) To what extent are these changes due to the FASB proposal? The FASB reporting proposal is only one factor underlying these changes. More important is the real financial pressure on firms due to the accelerating cost of retiree health care.

Left atrial hypertension causes pleural effusion formation in unanesthetized sheep.

We studied the effect of left atrial pressure (LAP) elevation on the formation of pleural effusion in unanesthetized sheep. We prepared the animals by placing catheters in the left atrium, pulmonary artery, femoral artery, and vein. We also placed a balloon catheter in the left atrium. After a recovery period of at least 1 wk, we measured LAP, pulmonary artery pressure (PAP), systemic arterial pressure, systemic venous pressure, cardiac output, plasma protein concentration, and plasma colloid osmotic pressure (pi c). We calculated capillary pressure (Pc) as 0.5(PAP - LAP). We then elevated LAP such that Pc-pi c was between -10 and 19.5 mmHg for 6-24 h. At the end of the experiment, we killed the sheep and measured the volume and protein concentration of the right pleural effusion. We also determined the extravascular fluid to blood free dry weight of the right lung. We found that pleural effusions and pulmonary edema formed when Pc-pi c greater than 5 mmHg. We also found that the pleural effusion volume correlated with the amount of pulmonary edema. Our data show that elevated LAP may cause pleural effusions, but only after pulmonary edema has developed.

PPOs: the employer perspective.

This paper reports the results of a national survey on employer experiences with preferred provider organizations (PPOs). The survey, conducted in 1987, included information from almost 700 telephone interviews with employee benefit managers. We found that 11 percent of employees are in PPOs. PPOs now have a strong presence among employers of all sizes. However, whereas they are a major force in the West, where almost one-third of employees are members, they have garnered only a 1 percent market share in the East. We examine the impact of PPOs on health insurance premiums and on employer satisfaction. The results show that in 1987, the year of the survey, PPOs appeared to provide mild cost savings compared to conventional insurance, and that employers were very satisfied with almost all aspects of PPOs, whereas they were surprisingly critical of their HMOs.

Conventional health insurance: a decade later.

In this article, the 1987 conventional health plans are examined and 1987 group health insurance is compared with that of 1977. The source of information for 1987 is the national survey of 771 private and public employers conducted by the Health Insurance Association of America. Data for 1977 are from the National Medical Care Expenditures Survey. Findings show that conventional health plans' share of the group market declined from 95 to 73 percent during the decade; the majority of Americans covered by conventional group insurance are now enrolled in a plan that self-insures; prospective utilization review grew dramatically after 1984; and patient cost sharing increased, but not as significantly as conventional wisdom holds.

Preferred provider organizations one year later.

One year ago we conducted the first comprehensive national survey of preferred provider organizations (PPOs). Results of this study demonstrated that, contrary to popular belief, there did indeed exist a "generic" PPO with clearly defined characteristics. Furthermore, we found that this new form of health delivery organization was rapidly expanding. A new national survey, completed in September 1986, shows continued brisk growth in the number of persons eligible to use PPO services. Utilization review programs have become more stringent and increasingly focus on physician practice patterns. One striking finding is that joint ventures between provider-sponsored PPOs and commercial insurers are multiplying.

Preferred provider organizations: issues for employers.

The preferred provider organization (PPO), an alternative delivery system currently embraced by the employer sector, has been growing at a phenomenal rate for the past few years. It is necessary to examine the issues an employer should consider when deciding whether to offer a PPO option, and to look at organizational issues such as PPO structure, quality, utilization review mechanisms, and benefits design.

Seizures following the withdrawal of alprazolam.

Seizures were observed following the withdrawal of alprazolam administered in therapeutic dose for 10 weeks. A review of available case reports suggests that seizures, like other withdrawal phenomena, are more apt to occur with short-acting benzodiazepines. To prevent their occurrence these drugs should be discontinued gradually and consideration given to substituting long-acting drugs during the withdrawal period. Physicians should remain alert to the fact that seizures may occur as early as 24 hours after the abrupt withdrawal of short-acting benzodiazepines.
