Hospitalization rates during potentially inappropriate medication use in a large population-based cohort of older adults.

BACKGROUND AND AIMS: The temporal relationship between potentially inappropriate medication (PIM) use and hospitalization remains uncertain. We examined whether current PIM use increases the rate of hospitalization and estimated the rate of hospitalization during exposure to individual PIMs. METHODS: A retrospective population-based cohort study of 1 480 137 older adults was conducted using the 2003-2013 Italian Emilia-Romagna Regional administrative healthcare database (~4.5 million residents), which includes demographic, hospital and outpatient prescription information. Each day of follow-up was defined as exposed/unexposed to PIMs that 'should always be avoided', according to the Maio criteria, an Italian modified version of the Beers criteria. The study outcome was all-cause hospitalizations. Crude PIM-related hospitalization rates were calculated for individual PIMs. Repeated-events Cox proportional hazards models with time-dependent covariates estimated adjusted hazard ratios for hospitalization during PIM exposure, as defined by three versions of the Maio criteria (v2007, v2011, v2014). RESULTS: During >10 million person-years of follow-up, 54.2% of individuals used ≥1 PIM and 10.9% of all person-time was exposed to v2014 PIMs. Among 1 604 901 hospitalizations, 15.6% occurred during v2014 PIM exposure. Crude hospitalization rates during v2014 PIM-exposed and unexposed person-time were 228.1 and 152.1 per 1000 person-years, respectively. The PIM with the highest rate of hospitalization was ketorolac, while nonsteroidal anti-inflammatory drugs had the most exposure time. The hazard of hospitalization was 16% greater (hazard ratio = 1.16; 95% confidence interval 1.14, 1.18) among patients exposed to v2014 PIMs. The v2007 and v2011 estimates were similar. CONCLUSIONS: In this large population-based cohort of older adults, we found a 16% increased hospitalization risk associated with PIM exposure.

A physician-focused intervention to reduce potentially inappropriate medication prescribing in older people: a 3-year, Italian, prospective, proof-of-concept study.

BACKGROUND: Potentially inappropriate medications (PIMs) are a preventable cause of negative clinical and economic consequences in older people. A range of educational interventions have attempted to address this in the past and have produced mixed results. OBJECTIVE: The objective of this study was to assess the effect of a physician-focused, multi-factorial, quality-improvement intervention on PIM prescribing in older patients in primary care. METHODS: This 3-year, multi-phase, prospective, proof-of-concept project introduced in 2007 was aimed at engaging all 303 general practitioners (GPs) in the Local Health Authority (LHA) of Parma, Italy, to positively influence the quality of prescribing to the entire older outpatient population (those aged at least 65 years) served by these physicians. The intervention focused on increasing GPs' awareness of prescribing for older people and included three key elements: (1) initial dissemination of a developed list of PIMs to always be avoided, along with a list of alternative drugs; (2) annual reviews of PIM incidence data; and (3) educational sessions on PIMs via academic detailing and case study reviews. Quarterly incidence rates of PIM exposure were calculated among all Parma LHA older outpatients who had received a prescription for any medication from their GP in a given quarter. The intervention was assessed by evaluating the changes in these rates between the study baseline (2007 fourth quarter [Q4]) and the end of the study (post-intervention: 2009 Q4). To reduce bias and confounding from background influences that may have acted to reduce PIM incidence rates independent of the intervention, these rate changes were also compared with those drawn from a similar neighbouring LHA over the same time period. RESULTS: Quarterly PIM exposure incidence rates among the older Parma LHA patients declined 31.4 % (7.8 % baseline to 5.3 % post-intervention), compared with 21.6 % in the comparator LHA (7.7 % to 6.1 %). The reduction in rates was significantly greater in the Parma LHA (p < 0.001), where the intervention resulted in 608 older patients (12.4 % of expected) being spared PIM exposure during 2009 Q4. PIM exposure rate reductions for NSAIDs and digoxin were each significantly greater in the Parma LHA than in the comparator LHA. CONCLUSIONS: By reaching out to GPs and maintaining contact with them, this quality intervention appears to have positively impacted physicians' awareness and prescribing behaviour, which led to significant reductions in PIM exposures and likely translated to significant population health benefits among their older patients. Similar interventions tailored to target specific PIMs or focus on certain subpopulations of GPs may further improve prescribing quality among older people.

The relationship between physician empathy and disease complications: an empirical study of primary care physicians and their diabetic patients in Parma, Italy.

PURPOSE: To test the hypothesis that scores of a validated measure of physician empathy are associated with clinical outcomes for patients with diabetes mellitus. METHOD: This retrospective correlational study included 20,961 patients with type 1 or type 2 diabetes mellitus from a population of 284,298 adult patients in the Local Health Authority, Parma, Italy, enrolled with one of 242 primary care physicians for the entire year of 2009. Participating physicians' Jefferson Scale of Empathy scores were compared with occurrence of acute metabolic complications (hyperosmolar state, diabetic ketoacidosis, coma) in diabetes patients hospitalized in 2009. RESULTS: Patients of physicians with high empathy scores, compared with patients of physicians with moderate and low empathy scores, had a significantly lower rate of acute metabolic complications (4.0, 7.1, and 6.5 per 1,000 patients, respectively, P < .05). Logistic regression analysis showed physicians' empathy scores were associated with acute metabolic complications: odds ratio (OR) = 0.59 (95% confidence interval [CI], 0.37-0.95, contrasting physicians with high and low empathy scores). Patients' age (≥69 years) also contributed to the prediction of acute metabolic complications: OR = 1.7 (95% CI, 1.2-1.4). Physicians' gender and age, patients' gender, type of practice (solo, association), geographical location of practice (mountain, hills, plain), and length of time the patient had been enrolled with the physician were not associated with acute metabolic complications. CONCLUSIONS: These results suggest that physician empathy is significantly associated with clinical outcome for patients with diabetes mellitus and should be considered an important component of clinical competence.
