Improving medication adherence and effective prescribing through a patient-centered prescription model in patients with multimorbidity.

PURPOSE: This study aimed to assess the impact of the patient-centered prescription (PCP) model in medication adherence and effective prescribing in patients with multimorbidity. METHODS: Uncontrolled before-after study in an intermediate care facility in a mixed urban-rural district. Inpatients aged ≥ 65 years with multimorbidity exposed to polypharmacy before hospital admission were consecutively enrolled. Every patient's treatment plan was analyzed through the PCP model, which includes interventions aimed at improving medication adherence. The primary endpoint was the change in the proportion of adherent patients between pre-admission and after discharge for all regularly scheduled long-term medications, using the proportion of days covered (PDC). Secondary endpoints included the change on mean PDC for all long-term medications, number of long-term medications, proportion of patients with hyperpolypharmacy, medication regimen complexity index (MRCI) score, drug burden index (DBI) score, number of potential inappropriate prescribing (PIP), and proportion of patients with ≥ 2 PIPs. RESULTS: Ninety-three non-institutionalized patients were included (mean age 83.0 ± SD 6.1 years). The proportion of adherent patients increased from 22.1 to 51.9% (P < 0.001). Intervention also improved mean PDC [mean difference (95% CI) 10.6 (7.7, 13.5)] and effective prescribing through a reduction on the number of long-term medications [- 1.3 (- 1.7, - 0.9)], proportion of patients exposed to hyperpolypharmacy (- 16.1%, P < 0.001), MRCI score [- 2.2 (- 3.4, - 1.0)], DBI score [- 0.16 (- 1.8, - 1.3)], number of PIPs [- 1.6 (- 1.8, - 1.3)], and proportion of patients with ≥ 2 PIPs (- 53.7%, P < 0.001). CONCLUSION: Studied intervention provides significant effective prescribing and medication adherence enhancements in non-institutionalized older patients with multimorbidity and polypharmacy.

Therapeutic optimization through goal-oriented prescription in nursing homes.

Background People living in nursing homes are highly vulnerable and frail. Polypharmacy and inappropriate prescription (IP) are also common problems. Objectives The objectives of the study are (i) to study the baseline situation and calculate the frailty index (FI) of the residents, (ii) to assess the results of routine clinical practice to do a pharmacotherapy review (patient-centred prescription (PCP) model) (Molist Brunet et al., Eur Geriatr Med. 2015;6:565-9) and (iii) to study the relationship between IP and frailty, functional dependence, advanced dementia and end-of-life situation. Setting Two nursing homes in the same geographical area in Catalonia (Spain). Method This was a prospective, descriptive and observational study of elderly nursing home residents. Each patient's treatment was analysed by applying the PCP model, which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal. Main outcome measure Prevalence of polypharmacy and IP. Results 103 patients were included. They were characterized by high multimorbidity and frailty. Up to 59.2% were totally dependent. At least one IP was identified in 92.2% of residents. Prior to the pharmacological review, the mean number of chronic medications prescribed per resident was 6.63 (SD 2.93) and after this review it was 4.97 (SD 2.88). Polypharmacy decreased from 72.55% to 52.94% and excessive polypharmacy fell from 18.62% to 5.88%.The highest prevalence of IP was detected in people with a higher FI, in those identified as end-of-life, and also in more highly dependent residents (p < 0.05). Conclusions People who live in nursing homes have an advanced frailty. Establishing individualized therapeutic objectives with the application of the PCP model enabled to detect 92.2% of IP. People who are frailer, are functionally more dependent and those who are end-of-life are prescribed with inappropriate medication more frequently.

Optimizing drug therapy in frail patients with type 2 diabetes mellitus.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is closely linked with ageing. In frail diabetic patients, the risks of intensive antidiabetic therapy outweigh the potential benefits. AIMS: To study the prevalence of T2DM in frail elderly patients, to identify inappropriate prescription (IP) of antidiabetic drugs and to study the relationship between patients' frailty index (FI) with polypharmacy and IP. METHODS: This was a prospective, descriptive, observational study of elderly patients. Each patient's antidiabetic treatment was analysed by applying the patient-centred prescription model (PCP), which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal. RESULTS: 210 patients with T2DM were included (25.15% prevalence). They were characterised by high multimorbidity and frailty. 93.3% presented polypharmacy and 51% excessive polypharmacy. IP was identified in 66.2% of patients. A statistically significant relationship was found between the progression in FI degree and IP prevalence (p < 0.05. During the admission, drug therapy regimens were modified in 97.1% of cases with IP (n = 136). DISCUSSION: These results suggest that in clinical practice T2DM treatment is not individualised, but rather is based on the same general recommendations for the population as a whole. CONCLUSIONS: There is a high prevalence of T2DM in the elderly. As the frailty of patients increases, so does the prevalence of IP. The application of PCP model enables drug therapy optimization in frail patients according to their main therapeutic goal, and contributes to provide clinical evidences on the applicability of a set of knowledge areas from the theoretical framework to the daily clinical practice.

[Pharmaceutical intervention with parenteral nutrition]. / Intervención farmacéutica en el ámbito de la nutrición parenteral.

OBJECTIVE: Description and analysis of pharmaceutical interventions for patients with parenteral nutrition and an assessment of the degree of acceptance. METHOD: Prospective six-month study. Design of a data collection sheet (with personal data, the indication for parenteral nutrition, hospital area, nutrition type, time and type of intervention, type of notification, acceptance) for recording interventions carried out based on normal activities: complete review of pharmacotherapy and clinical history. RESULTS: A total of 265 interventions were carried out during the study period (1.5 interventions/day) with a mean of 2.1 interventions/patient. The overall degree of acceptance was 83.77%; significant differences were found between type of communication for the intervention (oral and/or written) and the degree of acceptance. CONCLUSIONS: Adding a pharmacist to the care team permits direct intervention in partnership with the doctor, and it is an effective method for preventing and resolving the complications, generally metabolic, that are associated with parenteral nutrition. Using this process for resolving medication-related problems in hospitalised patients, principally in surgical areas, is an addition to the pharmacist's activities in the area of nutritional support.

[Optimising the quality of the unit dose dispensing process through the implementation of the semi-automated Kardex system]. / Optimización de la calidad del proceso de dispensación de medicamentos en dosis unitaria mediante la implantación del sistema semiautomático Kardex.

OBJECTIVE: To evaluate the effect of the incorporation of the semi-automated Kardex medication storage and dispensing system on the quality of the filling process of medicine trolleys in unit doses. METHOD: The speed of filling medicine trolleys in unit doses using the Kardex system was analysed retrospectively (n = 33,946 dispensings) and compared with the manual filling system (n = 5,284 dispensings); different filling procedures were used and compared. For each filling system and procedure, we obtained information for the number of dispensings and the time spent carrying this out. The speed of the process was calculated as the number of dispensings per hour. In addition, the drugs contained in the Kardex system were checked and the correspondence between both the actual and the theoretical content was assessed. RESULTS: The speed of the trolley filling process, expressed as the number of dispensings per hour, increased from 394 with the manual system (filling trolleys individually, n = 5,284 dispensings) to 417, 540 and 592 with the Kardex system when trolleys were filled individually (n = 16,530 dispensings), or grouped in two (n = 10,369 dispensings) or in three (n = 7,047 dispensings) respectively, at the start of the filling process. The check of the contents in the Kardex system detected 36% of trays with differences in quantity, one tray with out of date medication and three trays which should in theory have been empty and contained medication. CONCLUSIONS: The Kardex system optimises the speed of trolley filling with regard to the manual system, provided that the trolleys are grouped at the time of starting the preparation. The check of the cabinet contents shows that possibilities of error exist, related to its handling, which can be minimised by incorporating bar codes into the system s replenishment process.
