[Comparison of quality of life in patients living with HIV infection through pharmaceutical care according to CMO methodology vs. conventional follow-up. MAS-VIH project]. / Comparación de la calidad de vida en personas que viven con infección por VIH en seguimiento mediante atención farmacéutica según metodología capacidad motivación-oportunidad vs. seguimiento convencional. Proyecto MAS-VIH.

OBJECTIVE: To compare quality of life, in patients living with HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. METHODS: Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. RESULTS: 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%). CONCLUSIONS: The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up.

Application of CMO (capacity, motivation, and opportunity) methodology in pharmaceutical care to optimize the pharmacotherapy in older people living with HIV. DISPIMDINAC project.

OBJECTIVE: To determine the effectiveness of a pharmaceutical intervention, based on the CMO methodology (capacity, motivation and opportunity), to decrease the prevalence of the PIMDINAC concept (potentially inappropriate medication+drug interactions+non-adherence to concomitant medication) in people living with HIV infection. METHODS: Longitudinal prospective multicenter study, conducted between October 2021 and October 2022. Patients living with HIV older than 65 years, on antiretroviral treatment and concomitant drug prescription were included. Demographic, clinical, and pharmacotherapeutic variables were collected. Pharmaceutical care was provided for6 months according to the CMO model in each patient. The main variable was the percentage of patients who simultaneously fulfilled the PIMDINAC concept, comparing the baseline value with the same value at the end of the study. In addition, the percentage of patient's adherent to concomitant and antiretroviral treatment and the percentage of patients meeting the pharmacotherapeutic targets established for the prescribed medicationat 24 weeks of follow-up were compared. RESULTS: Sixty-eight patients were included. Seventy-two percent were men, with a median age of 68 years. The median number of concomitant drugs was 7. A 60.6% of the patients had polypharmacy. The prevalence of the presence of the PIMDINAC concept decreased significantly (10.3 vs. 0%). In isolation, each of the aspects also decreased significantly (p<0.031). The percentage of patients who met the objectives improved significantly from 48,5 at baseline to 88.2 (p<0.001). CONCLUSIONS: The pharmaceutical intervention based onarmaceutical intervention based on the CMO methodology significantly decreased the prevalence of the PIMDINAC concept and increased the number of patients who achieved the objectives, optimising their pharmacotherapy.

Implementation of safeguards to improve patient safety in chemotherapy.

PURPOSE: To evaluate the effectiveness of safeguards introduced in the process of using cytostatic agents for increasing the safety of oncology patients. METHODS: Prospective hospital study conducted in two stages, before and after the implementation of safeguards: staff training, standardized procedures, computerized prescription, pharmaceutical validation, implementation of bar codes, and a new manual on drug interactions. Medication errors (MEs) were actively recorded during the process of administering chemotherapy in the Medical Oncology Department. The study classified MEs by the stage of the medication process in which they occurred and assessed their severity. RESULTS: 500 patients, 250 before implementing safeguards and 250 afterward, were included in this study . Out of all patients included before, 43.1% had at least 1 error, compared to 27% of those included later. The number of MEs detected before and after was 144 vs. 95: 125 vs. 55 prescription errors, 2 vs. 5 validation errors, 14 vs. 4 preparation errors, 3 vs. 1 dispensation errors and 0 vs. 30 administration errors. The number of MEs that reached the patient before and after safeguard implementation was 16.7% vs. 6.3%. After the safeguards were introduced, all MEs that could have caused harm or required monitoring of some kind were prevented. CONCLUSIONS: Implementing safeguards in the hospital's cytostatic treatment cycle is useful for preventing MEs. Computerized prescription, pharmaceutical validation, and the creation/dissemination of proper work procedures are effective barriers that keep MEs from reaching the patient. Administering chemotherapy with a bar-code system facilitates detection error detection at this stage of the cycle and prevents them from reaching the patient.

[The role of the hospital pharmacist in the prevention, treatment and management of the side effects associated with antiretroviral treatment]. / Papel del farmacéutico de hospital en la prevención, identificación y manejo de los efectos adversos asociados al tratamiento antirretroviral.

At present, the side effects associated with antiretroviral treatment are the main reasons for discontinuation of this kind of therapy, both in clinical trials and in regular clinical practise. On the other hand, due to the change of direction that our profession has suffered in recent years, we face the need to establish a different relationship with the patient, achieving direct and effective Pharmaceutical Care within a framework of shared responsibility for therapeutic results. Pharmacist interventions should be aimed at improving the quality of life of patients, which can only be achieved with a multidisciplinary approach and individualised and adjusted to new patterns of toxicity of the drugs currently used. The pharmacist who does this work must know how to interpret these side effects, giving accurate information to the patient about both pharmacological and non-pharmacological treatment and correct pharmaceutical follow-up which clearly sets forth the criteria for referral to medical appointments. The aim of this paper is to establish baselines so that the hospital pharmacist can perform clearly and uniformly in the prevention, identification and management of major side effects: gastrointestinal, cardiovascular, dermatological, at the central nervous system and kidney level, associated with antiretroviral therapy.

[Analysis of the effectiveness of an antiemetic protocol used in an oncology division]. / Análisis de la efectividad de un protocolo de antiemesis implantado en la Unidad de Oncología.

OBJECTIVE: To analyse the effectiveness of an antiemetic protocol in patients receiving chemotherapy treatment. METHOD: Prospective study in patients with solid tumours receiving chemotherapy in an oncology day hospital between January 2006 and 2007. We conducted a literature review and an evaluation of the recommendations of different clinical practice guidelines. The emetogenic potential was calculated according to the Hesketh level (HL), and the antiemetic premedication was determined for each regimen. We evaluated the effectiveness of an antiemetic protocol by using a survey as a method for measuring emetic episodes and nausea in the acute and delayed phases. RESULTS: 172 patients completed the survey. 13.4% vomited in the acute phase and 16.9% in the delayed phase; the median number of times was 2 (1-8) and 1 (1-5) for each respective phase. With treatment regimens classed as HL 4-5, 18.5% experienced vomiting in the acute phase and 20.2% in the delayed phase, with 46% experiencing nausea in the acute phase and 38.4% in the delayed phase. Control of vomiting in patients with treatment regimens classed as HL 1-3 was 100% in acute phase and 91.7% in the delayed phase; nausea was reported by 27% in the acute phase and 31% in the delayed phase. The factors that contributed the most to the presence of vomiting and nausea were the emetogenic potential of the treatment regimen (p<0.05), vomiting in the previous cycle (p<0.05) and age younger than 50 years (p<0.002). DISCUSSION: The proposed antiemetic protocol is effective for controlling vomiting in chemotherapy regimens with an HL of 1-3. For highly emetogenic regimens, the antiemetic protocol is also effective, but protection is not complete. This protocol seems less effective for controlling nausea, although this is a subjective symptom which is difficult to assess and not routinely measured in clinical trials.

[Treatment with cetuximab in metastatic colorectal cancer patients who do not express the epidermal growth factor receptor]. / Tratamiento con cetuximab en pacientes con cáncer colorrectal metastásico que no expresan el receptor del factor de crecimiento epidérmico.

OBJECTIVE: To evaluate the response to cetuximab, in terms of time passed until disease progression and overall survival, in patients with colorectal cancer (CRC) in which the epidermal growth factor receptor (EGFR) is undetectable. METHOD: Nine EGFR-negative patients (confirmed by an immunohistochemistry study), who were being treated with cetuximab, were selected. Variables collected: demographic data, diagnosis, previous treatments, time since first metastasis to start of treatment with cetuximab, adverse events and tumour markers. The response was monitored using tumour markers and disease progression. Well-being was assessed using the Karnofsky performance status (KPS) or that of the Eastern Cooperative Oncology Group (ECOG). RESULTS: 22% men (2/9) with a median age of 48 (31-63). The median time from being diagnosed with the metastatic disease to the start of treatment with cetuximab was 19 months (12-48). All patients had failed an irinotecan-based regime, 77.77% (7/9) had also failed one which included oxaliplatin. The median number of cycles with cetuximab was 14 (6-32). The main adverse event was the appearance of an acneiform rash in 100% of the cases. The median time until disease progression was 7 months (3-16) and 10.2 months (4-24) for overall survival. The results for well-being showed a KPS of between 80-100% and an ECOG of < 2. The results obtained in the present study for overall survival and time until disease progression are higher than those in the pivotal study (10.2 compared to 8.6 months and 7 compared to 4.1 months respectively). CONCLUSIONS: According to the results obtained, the use of assessing the EGFR expression (by the immunohistochemistry technique at least), as a means of predicting response to treatment with cetuximab may be questioned. This suggests that selecting patients using the routine assessment of this receptor is inappropriate, since it excludes patients who may potentially benefit from the treatment. However, more clinical trials are required in this area in order to confirm these conclusions.
