Background Pharmaceutical validation consists of evaluating the medical prescription of patients, and checking the suitability of the prescribed treatment in terms of therapeutic objectives, patient characteristics and medication.

Purpose Analyse the pharmaceutical interventions performed in a hospital and quantify the degree of their acceptance.

Material and methods Prospective study lasting 2 months in a county hospital. All patients admitted with medical validation and subsequently pharmaceutical were included . Pharmaceutical interventions were codified as informative: clarification of the drug (CD), therapeutic equivalent (TEQ), low therapeutic usefulness (LTU) and medication not included in pharmacotherapeutic guide (NIG); and safety: incorrect dosage (ID), interaction between drugs (INT), therapeutic duplicity (TDUP), duration of incorrect treatment (DT), administration (AD), dose adjustment by age (AE), sequential therapy (SEC) and safety (SAF). The variables collected were: age, sex, prescribing service, type of intervention and degree of acceptance. Sources used: digital clinical history and electronic prescription program FarmaTools v. 1.9.

Results We analysed 244 pharmaceutical interventions. Population of mean age 46.5 years (range 2–92). 51% were females. The prescribing services were traumatology (29.09%), internal medicine (24.18%), surgery (14.34%), urology (6.97%), digestive and neurology (4.10%), cardiology (3.69%), mental health (3.28%), pneumology (2.87%), intensive care unit (1.64%), otorhinolaryngology and paediatrics (1.23%), nephrology, haematology and obstetrics 0.82%), and gynaecology and the palliative care unit (0.41%). Pharmaceutical interventions were: informative 6.97% (CD 4.51%, LTU 2.05%, NIG 0.41%) and safety 93.03% (TEQ 26.64%, DT 19.67%, SAF 18.44%, TDUP 13.52%, ID 8.61%, AD 3.28%, SEC 1.64%, INT 0.82%, AE 0.41%). The degree of acceptance was 100%.

Conclusion The results of the series studied show the highest degree of acceptance of pharmaceutical interventions, emphasising safety. Hence the importance of the work of the hospital pharmacist.
