Each patient's file contains certain pieces of important information from their name, patient number, dates of admission and discharge, diagnosis, and address. Amongst these important details there is nearly always note made of the result of each patient's treatment. The way this is recorded was set out to some degree by central guidelines and often falls into one of seven categories, namely non-TB, quiescent, improved, transferred, NMI (no medical improvement), died, and removed against advice.

A number of children were admitted to Stannington who were suspected as having tuberculosis but further investigation after their admission proved otherwise. Once this was determined these children would often only stay for about three months before being discharged home, and sometimes more appropriate alternative treatment would be advised for whatever condition they did have. Some commonly misdiagnosed illnesses were Perthes' hip, a childhood disorder resulting in destruction of the hip joint with similar symptoms to TB, and a whole range of pulmonary problems mistaken for TB.

Quiescent is by far the most commonly assigned result of treatment for patients in Stannington and was an indication that the treatment had been successful. If the disease had gone into quiescence it was seen to be inactive but there was always a risk of reactivity. Whereas patients labelled as NMI were those with extensive disease who were showing no improvement and by discharging them at this point they were essentially being sent home to die. The number of patients described as such was relatively few and in the early 1940s was never more than 2-3% of all admissions.

Inevitably there were deaths in Stannington but the numbers were not as great as one might expect. In comparison to the death rates from TB across the County of Northumberland as a whole during the same period they were very low. This may be an indication of the fact that children were often more resilient to adults or a reflection of the types of patients that were being admitted. Equally we might see it as a sign that Stannington was doing something right. From 1947 onwards death rates dwindled dramatically with the introduction of effective drug treatments.
