Reasons for use of hormone replacement therapy in women undergoing coronary angiography.

The recommendation has been made that all women be counseled about the risks and benefits of hormone replacement therapy (HRT). Use of HRT among women undergoing coronary angiography was explored to assess whether patterns of use were similar to data drawn from community samples. Using a descriptive design, a convenience sample of 414 postmenopausal women was interviewed. Fifty-eight percent had never used HRT, 18.3% were past users, and 23.7% were currently using HRT. The primary reason given for ever using HRT was for symptoms of menopause. Less than 14% of women cited coronary heart disease (CHD) or osteoporosis as their primary reason for using HRT. The most common reasons for stopping HRT were side effects and fear of cancer. The most common reasons given for never having used HRT were that their healthcare provider had never talked about it and that they had never thought about it. Use of HRT among women undergoing coronary angiography is similar to that found in community samples. The challenge is to promote patient-provider interactions that include information about HRT based on the scientific model as well as attention to women's individual concerns.

Teaching the teachers: creating an effective critical care preceptor program.

Staff nurse preceptors are integral members of effective critical care orientation programs. Much of the success of the orientation experience and orientee satisfaction depends on them. A critical care preceptor workshop containing a review of the orientation program and the application of educational principles in critical care settings has been found to be an effective method for assisting preceptors and for enhancing our orientation program.

Platelet inhibitors and hydroxyethyl starch: safe and cost-effective interventions in coronary artery surgery.

This study evaluated the cost-effectiveness and clinical safety of utilizing hetastarch in pump prime solutions and for colloid replacement postoperatively in conjunction with the platelet inhibitors, aspirin and Persantine (dipyridamole). Sixty-four adult patients undergoing a coronary artery bypass operation were divided into two groups. Group 1 (N = 32) received only Persantine (75 mg three times a day) on the day prior to operation. Group 2 (N = 32) received the same Persantine dose plus aspirin (325 mg). In both groups, aspirin and Persantine were continued postoperatively and hetastarch was used as the colloid of choice. All patients were evaluated for blood loss, coagulation profiles, cost of blood and colloid replacement, and clinical course. Group 2 patients demonstrated significantly greater blood loss (p less than 0.05) but the same postoperative coagulation profiles as Group 1. The transfusion requirement (3.6 units versus 1.3 units) and cost basis ($252 versus $91) for patient care were higher in Group 2. Hetastarch had no effect on blood loss and was not associated with any adverse clinical reactions. Annual institutional savings based on utilization of hetastarch were calculated at $33,500 to $40,500 per 500 patients. We conclude that preoperative administration of aspirin (325 mg) is associated with increased perioperative blood loss and higher patient costs, two variables not demonstrable with Persantine only. Use of hetastarch combined with postoperative platelet inhibition was clinically safe and was a cost-effective method of colloid replacement.

The public debate on social justice and health care: an opportunity for evangelization.

The most difficult moral choices arise at the point where social justice questions and medical-moral questions intersect. In an age of increasing technological advances and government intervention, Catholic health care facilities ought to shape a coherent moral policy that affirms human dignity and conforms to the Church's moral teaching.

Analysis of gait patterns in normal school-aged children.

The continuing development of gait in 60 children aged 7-16 years was studied with plantar surface-attached transducers to describe the time pressure profiles of foot segments during stance. Decreased pronation/supination of the subtalar and midtarsal joints was shown by simultaneous onset and simultaneous peak on medial and lateral heel sensors. The resultant midstance showed a rapid lateral-to-medial loading of the forefoot. The foot-flat position with decreased rotation about the longitudinal axis of the foot persists even after the temporal parameters of gait attain mature values.

Preserving the mission. Sponsors and lay leaders must collaborate to maintain the Church's presence in healthcare.

As the number of women and men religious involved in healthcare decreases, the Church faces the task of sustaining and expanding its institutional presence in the healthcare world. Both the Gospels and Church teaching support the claim that the Church should be involved in social institutions such as healthcare. Documents such as the Second Vatican Council's Pastoral Constitution on the Church in the Modern World stress the Church's concern with the impact of God's kingdom on all dimensions of human life. Pope Paul VI's Evangelization in the Modern World clearly affirms that the Gospel cannot be complete until it is interrelated with social life. Jesus' ministries of teaching and humble service are also paradigmatic for Catholic healthcare. To preserve and extend its institutional presence, Catholic healthcare will have to meet a number of challenges in the coming years. Catholic healthcare facilities must be prepared to relinquish their autonomy and work with others, providers will have to become attuned to what is distinctively Catholic about their facilities, and the Church must commit itself to preparing lay leaders for the Catholic healthcare ministry.
