Crucial times for general surgery.
“Specialization in general surgery” was the title of an editorial in the British Journal of Surgery in 1991, in which Johnson stated: “General surgery has a future, but the future requires increasing sub-specialization.” Apparently at that time it was a question of whether or not there was a future. How do we see the problem in 1999? Can we look at the issue from a European point of view? Altho...
متن کاملThe acceptability of waiting times for elective general surgery and the appropriateness of prioritising patients
BACKGROUND Problematic waiting lists in public health care threaten the equity and timeliness of care provision in several countries. This study assesses different stakeholders' views on the acceptability of waiting lists in health care, their preferences for priority care of patients, and their judgements on acceptable waiting times for surgical patients. METHODS A questionnaire survey was c...
متن کاملDo administrative databases accurately measure waiting times for medical care? Evidence from general surgery.
We abstracted the records of patients from general surgeons' offices in Winnipeg to compare waiting times from charts (i.e., the gold standard) with waiting times using administrative data. The administrative data method relies on physicians' billing data to identify a visit to the surgeon preoperatively to mark the start of the waiting time. There was no difference between waiting times using ...
متن کاملAnM[X]/G/1 Queue with Bernoulli Schedule General Vacation Times, General Extended Vacations, Random Breakdowns, General Delay Times for Repairs to Start and General Repair Times
Abstract This paper studies a batch arrival queueing system in which the server may face occasional random breakdowns. The repair process does not start immediately after a breakdown and there is a delay time waiting for repairs to start. Further, after every service completion the server has the option to leave for a vacation with probability p or continue serving with probability1 − p. The ma...
متن کاملStochastic bounds for a single server queue with general retrial times
We propose to use a mathematical method based on stochastic comparisons of Markov chains in order to derive performance indice bounds. The main goal of this paper is to investigate various monotonicity properties of a single server retrial queue with first-come-first-served (FCFS) orbit and general retrial times using the stochastic ordering techniques.
