Proper reporting of discharge diagnoses, including complications of medical care, is essential for maximum recovery of revenues under the prospective reimbursement system. To evaluate the effectiveness of abstracting techniques in identifying nosocomial infections at discharge, discharge abstracts of patients with nosocomial infections were reviewed during September through November of 1984. Patients with nosocomial infections were identified using modified Centers for Disease Control (CDC) definitions and trained surveillance technicians. Records which did not include the diagnosis of nosocomial infections in the discharge abstract were identified, and potential lost revenues were estimated. We identified 631 infections in 498 patients. On average, only 57 per cent of the infections were properly recorded and coded in the discharge abstract. Of the additional monies which might be anticipated by the health care institution to assist in the cost of care of adverse events, approximately one-third would have been lost due to errors in coding in the discharge abstract. Although these lost revenues are substantial, they constitute but a small proportion of the potential costs to the institution when patients acquire nosocomial infections.  相似文献

Since the mid-1970s, the Margaret Sanger Center of Planned Parenthood of New York City has prepared nurses and nurse midwives from less developed countries to be family-planning nurse practitioners. These nurse practitioners then provide services to patients, train other staff, and manage integrated family-planning clinics. More than 120 nurses and nurse midwives have arrived in groups of 10 at the Sanger Center, with 72 attending since 1981. Each course lasts 10 weeks. The core curriculum provides trainees with skills in women's health care including contraception, in training and advocacy, and in management of clinics. Whether, in the current period of scarce resources, cross-cultural training programs of this type remain a worthwhile investment, and if so, which of their components are most important to this success, is assessed.  相似文献

The difficulty in obtaining approval for payment of durable medical equipment by third party payers has impeded the rehabilitation program and discharge planning of many spinal cord patients throughout the country for many years. To gain some insight as to the number and level of patients affected, the kinds of equipment denied, the reasons given for the denial, which third party payers were mostly involved and how the patient and his/her family managed to cope or resolve this problem, a survey was undertaken. Letters were sent to 259 members of the American Spinal Injury Association (ASIA) asking them to list representative cases where requests for equipment deemed necessary were denied. Twenty-eight responses from different institutions were received from sixteen states describing 110 patients and 180 pieces of durable medical equipment denied in 1984 and 1985. Manual wheelchairs, motorized wheelchairs, shower/commode chairs, and environmental control units were the four most common equipment items denied by the third party payers. Government agencies ie., Medicaid, Medicare, Vocational Rehabilitation Departments and State Crippled Children's Services were the most frequent deniers, comprising 54% of the total sample. They were followed by private insurance (31%) and Workman's Compensation (3%). By far, the two most common reasons given for denials were: it was not covered by the insurance policy (38%) and it was not medically necessary (30%). Ninety (90) pieces of equipment (50%) were eventually obtained, most often by charity, or through the patient's family resources.  相似文献

Psychosocial issues are important variables that need to be addressed in patients with congestive heart failure (CHF). Unfortunately, these issues are often overlooked. Depression and lack of social support have been shown to have a negative impact on patients with CHF. Patients with CHF who are depressed or who lack social support have been shown to have increased morbidity and hospital readmission rates, to be less adherent to their medical regimen, and to have an overall increase in cost of care. The variables are often interrelated, as high levels of social support may lessen the impact of depression on mortality. In addition, certain biologic factors may influence the impact of psychosocial factors in patients with CHF. This review addresses the effects of depression, treatment adherence, and social support in patients with CHF and suggests interventions targeted to these problems. Health care professionals must assess these issues in all patients with CHF, address their specific needs, and intervene appropriately when warranted.  相似文献
