Calculating directly from the total patient visits at each clinic hour during the week, it can be seen that the maximum number of clinicians needed at any one time is eight, with only one patient waiting any significant length of time. The mean number of visits each day and the standard deviation can be used to asses a maximum number of expected patients; at 1.5 standard deviations higher than the mean (expected to contain 90% of all instances) the highest patient load is 22, which would require 11 clinicians. Assessment using the Poisson distribution gives slightly lower numbers, with 19 patients being the maximum load in ninety percent of cases, requiring 9 or 10 clinicians. The table provided calculates minimum staff needs based on real observations, resulting in no wait time for most patients.
There are currently too many clinicians employed in a very inefficient manner. Lowering the overall number of clinicians to just twelve (there is some inconsistency in the provided information here) and giving them more regular hours that are not fixed to appointment or walk-in arrivals will solve almost all wait-time and staff scheduling dilemmas. In the team schema, a minimum of four clinicians must be on staff at all times to ensure one team member is always available, and there will still not be a need for more than ten team members at any given time — two or three from each team. Again, combining walk-in and appointment arrivals rather than providing distinct services solves many of the noted problems without great complexity, and.
