Medication regimen complexity and prevalence of potentially inappropriate medicines in older patients after hospitalisation.

Background There is a relative paucity of information to characterise potential changes in medication regimen complexity and prevalence of prescribing of potentially inappropriate medications after hospitalisation, both in Australia and elsewhere. Objective To evaluate medication regimen complexity and the prevalence of potentially inappropriate medications before and after admission to hospital. Setting General medical units of a tertiary care hospital in Australia. Methods Retrospective cohort study of patients aged 65 years and above. Medication complexity was measured by using the Medication Regimen Complexity Index (MRCI). Main outcome measure The primary outcome was the change in the Medication Regimen Complexity Index for all prescribed medications after hospitalization. Results A convenience sample of 100 patients was included in the study. There was a significant change in the mean medication complexity score (as measured using the MRCI), increasing from 29 at the time of admission to 32 at the time of discharge (p < 0.05). Factors such as baseline medication regimen complexity (pre-admission MRCI) and length of stay in the hospitals appear to influence the change in medication complexity. However, the proportion of patients prescribed at least one potentially inappropriate medicine (PIM) decreased significantly, from 52% pre-hospitalization to 42% at discharge (p = 0.04). Conclusions Relative to the time of admission, overall medication complexity increased and the proportion of patients who were prescribed PIMs decreased after hospitalisation.

Effectiveness of a multidisciplinary home-based medication review program in reducing healthcare utilization among older adult Singaporeans.

AIM: The study aimed to: (i) evaluate the effectiveness of a multidisciplinary home-based medication review (HBMR) program in reducing hospital admissions and emergency department (ED) visits, cost of hospital admissions and length of stay (LOS); and (ii) determine the prevalence of drug-related problems (DRP) in elderly Singaporeans. METHODS: A retrospective observational study was carried out at an academic medical center in Singapore. Patients referred between 1 March 2011 and 31 December 2012 were included. Frequency of hospital admissions and ED visits, cost of hospital admissions, and LOS 6 months before and after HBMR, number of DRP, their categories, and their outcomes (i.e. resolved/ unresolved) were recorded. RESULTS: The analysis included 107 patients with a mean (SD) age of 75.6 years (7.6 years). HBMR resulted in a 41% reduction in risk for hospital admissions (Incidence rate ratio 0.59, 95% CI 0.47-0.73, P < 0.001). The same magnitude of reduction was observed for ED visits. The mean (SD) cost of hospital admissions reduced from $16 957.77 ($16 118.35) before HBMR to $7488.76 ($12 773.40) after (P < 0.001). Among 62 patients with hospital admissions before and after HBMR, the mean (SD) LOS decreased from 26.5 days (22.4 days) to 17.6 days (17.8 days; P = 0.010). The team identified 525 DRP from 1353 medications reviewed. Of these, 34 (6.7%) and 174 (34.1%) were resolved with and without physician involvement, respectively. The most common DRP identified were failure to receive drug (n = 163, 31.0%) and untreated indication (n = 140, 26.7%). CONCLUSIONS: The multidisciplinary HBMR program was associated with reduced ED visits, hospital admissions, LOS and costs in older adult Singaporeans with multiple DRP.

A questionnaire survey of patient experience with the Rheumatology Monitoring Clinic in Singapore.

AIM: The concept of a pharmacist/advanced practice nurse (APN)-led Rheumatology Monitoring Clinic (RMC) is a novel service in Singapore; we therefore conducted a questionnaire survey of patient experience. METHODS: Patients attending the RMC were provided with a set of questionnaires. As a substudy, a separate questionnaire was given to the rheumatologists and therapists conducting the RMC. RESULTS: Of the 105 patients surveyed, a total of 97 (92.4%) patients were satisfied/strongly satisfied with the overall service, and none were dissatisfied; 96% felt that the pharmacists/APNs provided clear, detailed information about their disease and medication, while 92% of patients were confident they knew what side-effects were possible. Ninety-two percent and 93% of patients were more likely to adhere to treatment, and were willing to come back for follow-up at the RMC, respectively. There was no difference in patient satisfaction in the average Likert summed scores, between the pharmacists and APNs. Age, gender, ethnicity and underlying disease did not exert any influence on the responses. All the rheumatologists surveyed were satisfied with the patients' management and the professionalism of the therapists. They opined that the RMC freed up time for them to see more complex cases. All the pharmacists/APNs concurred that the referrals were appropriately selected. CONCLUSIONS: We established the acceptability of a non-physician-led clinic in our local setting and highlighted the usefulness of having a routine clinic for monitoring medication toxicity and patient education. The RMC received positive feedback from patients, rheumatologists and allied health therapists, with a high degree of satisfaction among the respondents.
