In a hospital operating at full capacity a patient must be discharged prior to the admission of a new patient. In general, hospitals are service institutions which receive a random queue of service demanders (patients) whose admissions depends both on patient availability and on the hospital’s capacity to attend or admit a patient. Control and predictability rationalize costs and inventory expenses, this has long been known to proponents of total quality control management. This is true for hotels, airplanes companies, hospitals or any manufacturing production lines. The efficiency of a service provider institution depends largely on avoiding fluctuations between active and inactive periods. These findings show that if the daily difference between admissions and discharges is minimized, the number of inpatients would fluctuate less and the number of unoccupied beds would be reduced, thus optimizing the Hospital service. The discharges are replaced by admissions with some random delay and the random difference determines LFH Rw s. The factors determining LFH R were found to be the difference between daily admissions and discharges. Globally, inpatients Rw s in LFH, were found to be determined by the time elapsed between daily discharges and admissions. Rw analyzed with parametric or nonparametric statistics may simulate cycles and drifts which resemble seasonal variations or fake trends which reduce the Hospital’s efficiency. The sequence of daily admissions and patients staying on each service were found to be a kind of random series known as random walks ( Rw), sequences where what happens next, depends on what happens now plus a random variable. Conventional statistical analyzes and fractal dimension analyzes were performed on daily In-Patient series. Operative parameters of La Fuenfría Hospital such as: hospitalized patients daily admissions and discharges were studies for the hospital as a whole, and for each hospital’s service unit (henceforth called ‘ services’). Since these are also protected by Spanish and EU laws on personal information privacy they were remove prom data posted in PLoS ONE. LFH Command Panels also include names and ID codes of Hospital personnel for administrative purposes. The translated Command panels are provided to PLoS One, and are freely available to anyone interested in them. All the original La Fuenfría Hospital “Cuadros de Mando” which we translate “Command panels” spreadsheets cis be provided with this revised manuscript.
