The UNOS OPTN (Organ Procurement and Transplantation Network) waiting list: 1988 through November 30, 1992.

Based on data from the OPTN Waiting List and the Scientific Registry between 1988 and 1992: 1. The number of registrations on the overall waiting list increased by 81% between December 31, 1988 and November 30, 1992. On November 30, 1992, there were 29,047 registrations for a transplant in the United States. Organ-specific waiting lists showing strong increases during the period were lung (1,277%), liver (262%), and heart (162%). The number of heart-lung registrants decreased during the period. 2. Overall, Whites comprised the largest percentage of waiting-list registrants, followed by Blacks and Hispanics. This frequency distribution remained relatively constant between 1988 and 1991. On the organ-specific waiting lists, the percentage of Whites ranged from 80% on the liver waiting list to 90% on the pancreas waiting list. Blacks make up about 12% of the United States population, but about 32% of the kidney waiting list, due to the high incidence of end-stage renal disease among Blacks in the United States. 3. The frequency distribution of age on the waiting lists is shifting toward a greater proportion of potential recipients age 45 or older. This trend was especially true for the liver, lung, and pancreas waiting lists. 4. The percentage of highly sensitized registrants (PRA > or = 80%) on the kidney waiting list decreased by 8% between 1988 and 1991. The percentage of registrants with PRA less than 20% increased by 11.3%, probably as a result of longer waiting times for low-PRA registrants. 5. A result of the growth of the waiting lists was an increase in the median waiting time to transplant during the period. This effect was observed on every waiting list except the heart-lung. The wait for a liver transplant was the shortest (67 days in 1991), whereas the wait for a heart-lung transplant was the longest (543 days in 1990). 6. The overall death rate remained relatively stable, but was up slightly in 1991, when 6.1% of registrants died while waiting for a transplant (compared with 5.6% in 1990). The death rate on the heart-lung waiting list fell from 23.5% in 1988 to 14.8% in 1991, probably because of fewer heart-lung registrations. In 1991, the death rates were highest on the thoracic waiting lists (11.7-14.8%), followed by liver (9.3%), kidney (3.7%), and pancreas (3.0%). 7. The percentage of patients in the most urgent medical status categories remained stable on the heart waiting list and has decreased on the liver waiting list.

Waiting list hurdles and the role of the pre-surgical booking clinic.

Patients requiring surgery have two main hurdles to cross--long waiting lists and the risk of late cancellation when dates become available. A study was conducted to investigate the inconvenience caused by late cancellation, and to show how the pre-surgical assessment clinic can be utilised to reduce the dissatisfaction and disappointment of the current waiting list system in surgery.

Adapting to waiting lists for coronary revascularization. Do Canadian specialists agree on which patients come first?

STUDY OBJECTIVES: To assess specialists' adaptation to long waiting lists for coronary revascularization, and their acceptance of a formal queue-ordering schema proposed by an expert panel. DESIGN: Mail survey of practitioners in referral centers using 49 hypothetical case scenarios. Scenarios were rated for maximum acceptable delay prior to coronary surgery, on a scale with seven interventional time frames graded from emergency to three to six months' permissible delay. The survey included the proposed schema and rating system; respondents were invited to differ as they saw fit. HYPOTHETICAL PATIENTS: Assumed uniformly to be middle aged with typical angina, but clinical factors varied, eg, severity and stability of angina, response to medical therapy, coronary anatomy, and noninvasive test results. PHYSICIAN SUBJECTS: There were 122 respondents, for a 60 percent response rate, including a majority of cardiac surgeons and invasive cardiologists on staff in Ontario teaching hospitals. MEASUREMENTS AND RESULTS: Fifty-seven percent rated some scenarios for acceptable waiting times of three to six months; another 39 percent rated their least urgent scenarios to wait six weeks to three months. Interpractitioner agreement was high: for 48/49 scenarios, at least 75 percent of urgency ratings fell within two contiguous points on the scale. Symptom status was the dominant determinant of waiting time, with mean maximum acceptable wait of 74 days for patients with mild-moderate stable angina but three days for those receiving parenteral nitroglycerin (p less than 0.00001). About half the ratings matched those predicted based on the original panel's consensus criteria; 90 percent were within one scale point. CONCLUSIONS: Specialist practitioners in Ontario have adapted to waiting lists for coronary artery bypass surgery/percutaneous transluminal coronary angioplasty, and assess the priority of hypothetical patients in similar ways and in reasonable accord with formal queue-ordering criteria. This behavior may help mitigate the impact of resource constraints, allowing delay of services for those with less acute need--a potential contrast to delayed access in America based on low income or lack of insurance.

Waiting list information strategies for child psychiatry: an intervention and measurement approach.

This paper describes a number of steps we have initiated to study our chronic waiting list problems. We describe a program involving monthly data collection which has enabled us to document the effectiveness of some strategies and predictive variables. During 1989 the data were supplemented with information collected by a questionnaire mailed to every other referral. We found that an initial response to the questionnaire was a powerful predictor of successfully kept first appointments six to 12 months later. The significance of these differences, the impact of our tracking procedures and the issues and causes, along with some strategies, are discussed.

Rationing out-patients: a defence of the waiting list.

New psychiatric out-patients were offered immediate or delayed appointments (average delay 12 weeks) in random order. The two groups thus formed, comprising 234 patients, were shown to be comparable in some important respects. Immediate appointments were taken up significantly more frequently than delayed appointments, and 12 per cent of immediate and 22 per cent of delayed patients did not receive any psychiatric service. No evidence was found that delay increased other medical services supplied. Non-attenders were presumed to suffer from "neurosis" and "personality problem". Initial attenders used more services than those who failed to keep their first appointment but came later. A waiting list is proposed as a screening device to limit out-patient referrals.
