The effects of pharmaceutical firm enticements on physician prescribing patterns. There's no such thing as a free lunch.

We examined the impact on physician prescribing patterns of pharmaceutical firms offering all-expenses-paid trips to popular sunbelt vacation sites to attend symposia sponsored by a pharmaceutical company. The impact was assessed by tracking the pharmacy inventory usage reports for two drugs before and after the symposia. Both drugs were available only as intravenous preparations and could be used only on hospitalized patients. The usage patterns were tracked for 22 months preceding each symposium and for 17 months after each symposium. Ten physicians invited to each symposium were interviewed about the likelihood that such an enticement would affect their prescribing patterns. A significant increase in the prescribing pattern of both drugs occurred following the symposia. The usage of drug A increased from a mean of 81 +/- 44 units before the symposium to a mean of 272 +/- 117 after the symposium (p less than 0.001). The usage of drug B changed from 34 +/- 30 units before the symposium to 87 +/- 24 units (p less than 0.001) after the symposium. These changed prescribing patterns were also significantly different from the national usage patterns of the two drugs by hospitals with more than 500 beds and major medical centers over the same period of time. These alterations in prescribing patterns occurred even though the majority of physicians who attended the symposia believed that such enticements would not alter their prescribing patterns.

Home parenteral nutrition.

Home parenteral nutrition is a life-sustaining mode of therapy for patients with short bowel syndrome that is unresponsive to conventional therapy. It requires learning specialized skills through an intensive training program and carefully following this program in a home setting. This training can be best provided by a group of health care specialists including a physician, nurse, dietitian, psychiatrist, social worker, and pharmacist who are knowledgeable about the issues that face the patient requiring home parenteral nutrition. The resources of career medical centers ar most appropriately utilized to provide the support needed to successfully undertake a home parenteral nutrition program. The nutritional requirements of these truly long-term patients have to be more accurately defined to guarantee that macronutrient and micronutrient requirements are being adequately provided for over the many years of required treatment. Fluid delivery systems and techniques for infection-free long-term venous catheterization have to be perfected. Home parenteral nutrition is a valuable life support system for patients with gut failure. Although expensive, it costs substantially less than in-hospital parenteral nutrition and can return the patient to a near normal life at home.

Cost of a home parenteral nutrition program.

We analyzed the costs to a hospital of providing complete home parenteral nutrition (HPN) services for eight patients. Identified cost components include patient training, equipment, supplies, and follow-up. The average annual cost of maintaining parenteral nutrition at home was 73% lower than it would have been in the hospital. The establishment of private companies to provide patients with HPN supplies and services will reduce the financial burden of HPN programs for hospitals.

The current status of home total parenteral nutrition.

The history and current status of home total parenteral nutrition are reviewed. Patients without a functional intestinal tract are able to lead a relatively normal life, infusing their essential nutrients through a Silastic central venous catheter while they sleep at night. The average catheter life is nine months. Suspected sepsis and obstruction of the catheter were the leading causes for catheter removal.
