Abstract
BACKGROUND
The concept of pharmaceutical care (PC) specifically refers to the pharmacist being able to identify, prevent and resolve negative outcomes associated with medication (NOM). According to the Third Consensus of Granada, these are patient health-related outcomes not consistent with pharmacotherapy objectives, and are associated with the proper or erroneous use of medicines. In this way, pharmacists might provide the pharmacist to provide the correct use of medicines to patients who are attended at home.
OBJECTIVE
This study aimed to detect, classify and quantify NOM, according to the Third Consensus of Granada, in patients treated at home, who were assisted by the Home Assistance Programme of the University Hospital of University of Paulo, Brazil.
METHOD
A descriptive, observational and cross-sectional study was conducted. The pharmacotherapy plan was filled during the interview with the patient or caregiver.
RESULTS
The study included 87 patients with a mean age of 66 years old, adults (89%), children (11%), female (58%) and retired (62%). A total of 62% patients presented NOM, with an average of 1.13 NOM per patient. The NOM included untreated health problems (20.6%), effects from unnecessary medicines (9.1%), non-quantitative ineffectiveness (34.5%), quantitative ineffectiveness (3.4%), non-quantitative safety problems (11.4%) and quantitative safety problems (3.4%). Patients with the following characteristics were more prevalent than expected in the NOM effectiveness group: those aged between 65 and 74 years (p=0.0199), those with a low education level (p=0.0266), those with increased comorbidity (p=0.0461), those using medicine for the digestive tract and metabolism (p=0.0475) and those using medicine for blood and blood-forming organs (p=0.0466). For the NOM necessity group, patients with endocrine, nutritional and metabolic diseases (p=0.0587) were in greater numbers than expected; and for the NOM safety group, only patients aged over 74 years (p=0.01809) were in greater numbers.
CONCLUSION
For this population, it was concluded that there were several factors related to the occurrence of NOM: age, education, number of comorbidities, use of medicines for the digestive tract and the metabolism and medicines for blood and blood-forming organs. The use of the Third Consensus of Granada classification was very important for the recognition and measurement of NOM.
