When the Visiting Nurse Association of Central Illinois staff began to investigate Medicare Hospice Benefit Certification, they had to start from scratch. In this first-person account, they share their experience and valuable informational shortcuts to help others streamline their process and assure adequate preparation for the certification survey and subsequent operation.
Rates of bacteremia among hospitalized patients with central venous catheters range up to 21%. Few data exist for home intravenous therapy (IVT). We studied 300 patients from two hospital-based home IVT services in 29 months. Diagnoses included 92 cases of osteomyelitis, 33 of pneumonia, 35 of malnutrition, 26 of chronic pain, and 114 of other diseases. Peripheral IVT was given to 97 patients. Mean age was 39.4 years (range, 0.3-98). Hickman, Infuse-A-Port, Broviac, Arrow triple lumen, Hohn, and peripherally inserted central catheters (PICC) were used for a mean of 44 days. Six bacteremias (one death) (2%, 4.6/10,000 catheter days), two subclavian thromboses, 13 catheter site infections, and one additional death occurred. PICC experience included 76 patients, mean age 46 years (range, 4-76), primarily with infections, chronic pain, or dehydration. Mean duration of therapy was 24 days (0-67) and was completed in 51 patients; others completed therapy with standard peripheral catheters a mean of 6 days later. Complications included 17 obstructions by clot, 11 cases of phlebitis, six catheter fractures, five punctures, two accidental removals, and one infiltration. Liquid silicone repaired holes; urokinase opened clots. Successful completion of therapy was more common in the second year, 88% versus 57%. Despite more complications, patients, home IVT nurses, and physicians preferred PICCs. We conclude that home IVT is safe via many means of access, with fewer infections than with hospital care. Such infections may be termed "nosohusial."
We evaluated 1,266 persons who had received external radiotherapy for benign diseases in childhood. The evaluation used detailed questionnaires completed by trained interviewers and neoplastic disease registry data. The control population included 958 age-, sex-, race-, and disease-matched persons who had not received radiotherapy and 9,865 family members of the two study groups. An excess number of clinically important thyroid neoplasms, both benign and malignant, was noted in the irradiated group.
