Implementation of Partnered Pharmacist Medication Charting in haematology and oncology inpatients.

AIM: Partnered Pharmacist Medication Charting (PPMC) in patients admitted under general medical units has been shown to reduce medication errors. The aim of this study is to evaluate the impact of the PPMC model on medication errors in patients admitted under cancer units in Victorian hospitals. METHODS: A prospective cohort study comparing cohorts before and after the introduction of PPMC was conducted. This included a 2-month pre-intervention phase and 3-month intervention phase. PPMC was implemented during the intervention phase as new model of care that enabled credentialed pharmacists to chart all admission medications, including pre-admission or new medications and cancer therapies, in collaboration with the admitting medical officer. The proportion of medication charts with at least one error was the primary outcome measure. RESULTS: Seven health services across Victoria were included in the study. The majority of health services were using paper-based prescribing systems for oncology. Of the 547 patients who received standard medical medication charting, 331 (60.5%) had at least one medication error identified compared to 18 out of 416 patients (4.3%) using the PPMC model (p < 0.001). The median (interquartile range) inpatient length of stay was 5 (2.9-10.6) days in pre-intervention and 4.9 (2.9-11) days in intervention (p = 0.88). In the intervention arm, 42 patients had cancer therapy charted by a pharmacist with no errors. CONCLUSIONS: PPMC was successfully scaled into cancer units as a collaborative medication safety strategy. The model was associated with significantly lower rates of medication errors, including cancer therapies. PPMC should be adopted more widely in cancer units in Australia.

Introduction of a modified analgesic ladder in the emergency depart-ment: Effect on oxycodone use for back pain.

OBJECTIVE: The aim of this study was to assess the introduction of an analgesic ladder and targeted education on oxycodone use for patients presenting to the emergency department (ED). DESIGN: A retrospective pre-post implementation study was conducted. Data were extracted for patients presenting from June to July 2016 (preintervention) and June to July 2017 (post-intervention). SETTING: The EDs of a major metropolitan health service and an affiliated community-based hospital. PARTICIPANTS: Patients with back pain where nonpharmacological interventions such as mobilization and physiotherapy are recommended as the mainstay of treatment. INTERVENTIONS: A modified analgesic ladder introduced in May 2017. The ladder promoted the use of simple analgesics such as paracetamol and nonsteroidal anti-inflammatory drug (NSAIDs) prior to opioids and tramadol in preference to oxycodone in selected patients. MAIN OUTCOME MEASURE(S): The proportion of patients prescribed oxycodone and total doses administered. RESULTS: There were 107 patients pre and 107 post-intervention included in this study. After implementation of the analgesic ladder, 78 (72.9 percent) preintervention patients and 55 (51.4 percent) post-intervention patients received oxycodone in ED (p = 0.001). The median oxycodone doses administered in the ED was 14 mg (interquartile range: 5-20 mg) and 5 mg (interquartile range: 5-10 mg; p < 0.001), respectively. On discharge from hospital, a prescription for oxycodone was issued for 36 (33.6 percent) patients preintervention and 26 (24.3 percent) patients post-intervention (p = 0.13). CONCLUSIONS: Among patients with back pain, implementation of a modified analgesic ladder was associated with a statistically significant but modest reduction in oxycodone prescription. Consideration of multifaceted interventions to produce major and sustained changes in opioid prescribing is required.

The efficacy and safety of varenicline alone versus in combination with nicotine lozenges for smoking cessation among hospitalised smokers (VANISH): study protocol for a randomised, placebo-controlled trial.

INTRODUCTION: Smoking is a leading cause of premature deaths globally. The health benefits of smoking cessation are many. However, majority of quit attempts are unsuccessful. One way to potentially improve success rates is to evaluate new combinations of existing smoking cessation therapies that may work synergistically to decrease the intensity of withdrawal symptoms and cravings. AIMS: To evaluate the feasibility, efficacy and safety of the combination of varenicline and nicotine replacement therapy (NRT) lozenges versus varenicline alone in assisting hospitalised smokers to quit. METHODS AND ANALYSIS: This is a multicentre, randomised, placebo-controlled trial. Adults with a history of smoking ≥10 cigarettes per day on average in the 4 weeks prior to their hospitalisation will be recruited. Participants will be randomly assigned to either the intervention group and will receive varenicline and NRT lozenges, or the control group and will receive varenicline and placebo lozenges. All participants will be actively referred to behavioural support from telephone Quitline. Participants are followed up at 1 and 3 weeks and 3, 6 and 12 months from the start of treatment. The primary outcome is carbon monoxide validated prolonged abstinence from 2 weeks to 6 months after treatment initiation. Secondary outcomes include self-reported and biochemically validated prolonged and point prevalence abstinence at 3, 6 and 12 months, self-reported adverse events, withdrawal symptoms and cravings, adherence to treatment, Quitline sessions attended and others. According to the Russell Standard, all randomised participants will be accounted for in the primary intention-to-treat analysis. ETHICS AND DISSEMINATION: The trial will be conducted in compliance with the protocol, the principles of Good Clinical Practice, the National Health and Medical Research Council National Statement on Ethical Conduct in Human Research (updated 2015) and the Australian Code for the Responsible Conduct of Research (2018). Approval will be sought from the Human Ethics Committees of all the participating hospitals and the university. Written informed consent will be obtained from each participant at the time of recruitment. TRIAL REGISTRATION NUMBER: Australia New Zealand Clinical Trials Registry (ACTRN12618001792213).

Statin use and fall-related hospitalizations among residents of long-term care facilities: A case-control study.

BACKGROUND: Statins are associated with muscle-related adverse events, but few studies have investigated the association with fall-related hospitalizations among residents of long-term care facilities (LTCFs). OBJECTIVE: The objective of the study is to investigate whether statin use is associated with fall-related hospitalizations from LTCFs. METHODS: A case-control study was conducted among residents aged ≥65 years admitted to hospital from 2013 to 2015. Cases (n = 332) were residents admitted for falls and fall-related injuries. Controls (n = 332) were selected from patients admitted for reasons other than cardiovascular and diabetes. Cases and controls were matched 1:1 by age (±2 years), index date of admission (±6 months), and sex. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using conditional logistic regression, after considering for history of falls, hypertension, dementia, functional comorbidity index, polypharmacy (≥9 regular preadmission medications), and fall-risk medications. Subanalyses were performed for individual statins, dementia, and statin intensity. RESULTS: Overall, 43.1% of cases and 27.1% of controls used statins. Statins were associated with fall-related hospitalizations (aOR = 2.24, 95% CI 1.56-3.23), in particular simvastatin (aOR = 2.26, 95% CI 1.22-4.20) and atorvastatin (aOR = 2.08, 95% CI 1.33-3.24). Statins were associated with fall-related hospitalizations in residents with (aOR = 2.34, 95% CI 1.33-4.11) and without dementia (aOR = 2.30, 95% CI 1.46-3.63). There was no association between statin intensity and fall-related hospitalizations (aOR = 0.78, 95% CI 0.43-1.40). CONCLUSION: This study suggests a possible association between statin use and fall-related hospitalizations among residents living in LTCFs. However, there was minimal evidence for a relationship between statin intensity and fall-related hospitalizations. Further research is required to substantiate these hypothesis-generating findings.

The role of medication advisory committees in residential aged care services.

BACKGROUND: There is increasing international interest in initiatives to reduce medication-related harm and preventable hospitalizations in residential aged care services (RACS). The Australian Government recommends that RACS establish multidisciplinary Medication Advisory Committees (MACs). No previous research has specifically investigated the structures and functioning of MACs. OBJECTIVES: To explore the current structures and functioning of MACs, and identify opportunities for MACs to better promote safe and effective medication use. METHODS: Semi-structured interviews and focus groups were conducted with a maximum variation sample of health professionals (n = 44) across four health services operating across 27 RACS in rural and regional Victoria, Australia. Qualitative data were analyzed using deductive and inductive content analyses. Results were presented to a multidisciplinary expert panel (n = 13) to identify opportunities for improvement. RESULTS: Deductively coded themes included composition and functioning of the MAC, education and information needs and support to better manage polypharmacy. Emergent inductively coded themes included general medical practitioner (GP) and pharmacist engagement, collaboration and effectiveness. Participation by GPs and pharmacists was variable, while no MACs involved residents or family carers. Aged care specific and multidisciplinary MACs were generally more proactive in addressing potential medication-related harm. Education to identify and report adverse drug events with high risk medications was identified as a priority. The multidisciplinary panel made 12 recommendations to promote safe and effective medication use. CONCLUSION: Despite all MACs having a strong commitment to medication safety, opportunities exist to improve the composition and structure, proactive identification and response to emerging issues, and systems for staff, resident and family carer training.

Proton Pump Inhibitors and Infection-Related Hospitalizations Among Residents of Long-Term Care Facilities: A Case-Control Study.

OBJECTIVE: Our objective was to investigate associations between proton pump inhibitor (PPIs) use and infection-related hospitalizations among residents of long-term care facilities (LTCFs). METHODS: This was a case-control study of residents aged ≥ 65 years admitted to hospital between July 2013 and June 2015. Residents admitted for infections (cases) and falls or fall-related injuries (controls) were matched for age (± 2 years), sex, and index date of admission (± 6 months). Conditional logistic regression was used to estimate crude and adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for associations between PPI use and infection-related hospitalizations. Analyses were adjusted for age, sex, polypharmacy, diabetes, heart failure, chronic obstructive pulmonary disease, myocardial infarction, cerebrovascular accident, and concomitant use of cancer and immunosuppressant medications. Subgroup analyses were performed for high- and low/moderate-intensity PPIs and for respiratory and non-respiratory infections. Logistic regression was used to compare the odds of infection-related hospitalizations among users of high- and low/moderate-intensity PPIs. RESULTS: Overall, 181 cases were matched to 354 controls. Preadmission PPI use was associated with infection-related hospitalizations (aOR 1.66; 95% CI 1.11-2.48). In subgroup analyses, the association was apparent only for respiratory infections (aOR 2.26; 95% CI 1.37-3.73) and high-intensity PPIs (aOR 1.93; 95% CI 1.23-3.04). However, the risk of infection-related hospitalization was not significantly higher among users of high- versus low/moderate-intensity PPIs (aOR 1.25; 95% CI 0.74-2.13). CONCLUSION: Residents who use PPIs may be at increased risk of infection-related hospitalizations, particularly respiratory infections. Study findings provide further support for initiatives to minimize unnecessary PPI use in the LTCF setting.

Factors associated with nicotine replacement therapy use among hospitalised smokers.

INTRODUCTION AND AIMS: Nicotine replacement therapy (NRT) is recommended as a smoking cessation aid for hospitalised smokers. We examined factors associated with NRT use during hospitalisation and after discharge, and NRT uptake when systematically offered free of cost. DESIGN AND METHODS: A nested analysis was conducted using data from a clinical trial that evaluated the effectiveness of a pharmacist-led smoking cessation intervention in 600 hospitalised smokers. RESULTS: NRT was used at least once by 285 (48%) participants during hospitalisation and by 287 (48%) participants during the 12 months post-discharge. Heavy smokers and those who expressed interest in using NRT for their next quit attempt at baseline interview were more likely to use NRT during hospitalisation [odds ratio (OR) 1.94, 95% confidence interval (CI) 1.38, 2.74; OR 2.09, 95% CI 1.48, 2.95] and after discharge (OR 1.70, 95% CI 1.20, 2.41; OR 1.97, 95% CI 1.39, 2.79). Those using six or more medications were more likely to use NRT during hospitalisation (OR 1.65, 95% CI 1.05, 2.61). Post-discharge NRT users were more likely to have been initially admitted for a respiratory or cardiac problem (OR 1.51, 95% CI 1.05, 2.18). When NRT was offered free of cost to a subset of patients (n = 300), 157 (52%) used NRT during hospitalisation. Nicotine dependence and interest in using NRT predicted its use (OR 2.26, 95% CI 1.38, 3.70; OR 2.58, 95% CI 1.58, 4.20). DISCUSSION AND CONCLUSIONS: Targeting heavy smokers, those with cardio-respiratory conditions and those interested in using NRT regardless of regimen complexity could improve NRT uptake.

Prevalence and Variability in Medications Contributing to Polypharmacy in Long-Term Care Facilities.

BACKGROUND: Research into which medications contribute to polypharmacy and the variability in these medications across long-term care facilities (LTCFs) has been minimal. OBJECTIVE: Our objective was to investigate which medications were more prevalent among residents with polypharmacy and to determine the variability in prescribing of these medications across LTCFs. METHODS: This was a cross-sectional study of 27 LTCFs in regional and rural Victoria, Australia. An audit of the medication charts and medical records of 754 residents was performed in May 2015. Polypharmacy was defined as nine or more regular medications. Logistic regression was performed to determine the association between medications and resident characteristics with polypharmacy. Analyses were adjusted for age, sex and Charlson's comorbidity index. Variability in the use of the ten most prevalent medication classes was explored using funnel plots. Characteristics of LTCFs with low (< 30%), moderate (30-49%) and high (≥ 50%) polypharmacy prevalence were compared. RESULTS: Polypharmacy was observed in 272 (36%) residents. In adjusted analyses, each of the top ten most prevalent medication classes, with the exception of antipsychotics, were associated with polypharmacy. Between 7 and 23% of LTCFs fell outside the 95% control limits for each of the ten most prevalent medications. LTCFs with ≥ 50% polypharmacy prevalence were predominately smaller. CONCLUSION: Polypharmacy was associated with nine of the ten most prevalent medication classes. There was greater than fourfold variability in nine of the ten most prevalent medications across LTCFs. Further studies are needed to investigate the clinical appropriateness of the variability in polypharmacy.

Medication Use and Fall-Related Hospital Admissions from Long-Term Care Facilities: A Hospital-Based Case-Control Study.

BACKGROUND: Falls are a leading cause of preventable hospitalizations from long-term care facilities (LTCFs). Polypharmacy and falls-risk medications are potentially modifiable risk factors for falling. OBJECTIVE: This study investigated whether polypharmacy and falls-risk medications are associated with fall-related hospital admissions from LTCFs compared with hospital admissions for other causes. METHODS: This was a hospital-based, case-control study of patients aged ≥65 years hospitalized from LTCFs. Cases were patients with falls and fall-related injuries, and controls were patients admitted for infections. Conditional logistic regression was used to calculate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between polypharmacy (defined as the use of nine or more regular pre-admission medications) and falls-risk medications (categorized as psychotropic medications and those that can cause orthostatic hypotension) with fall-related hospital admissions. RESULTS: There was no association between polypharmacy and fall-related hospital admissions (adjusted OR 0.97, 95% CI 0.63-1.48); however, the adjusted odds of fall-related hospital admissions increased by 16% (95% CI 3-30%) for each additional falls-risk medication. Medications that can cause orthostatic hypotension (adjusted OR 1.25, 95% CI 1.06-1.46), but not psychotropic falls-risk medications (adjusted OR 1.02, 95% CI 0.88-1.18) were associated with fall-related hospital admissions. The association between medications that can cause orthostatic hypotension and fall-related hospital admissions was strongest among residents with polypharmacy (adjusted OR 1.44, 95% CI 1.08-1.92). CONCLUSION: Polypharmacy was not an independent risk factor for fall-related hospital admissions; however, medications that can cause orthostatic hypotension were associated with fall-related hospital admissions, particularly among residents with polypharmacy. Falls-risk should be considered when prescribing medications that can cause orthostatic hypotension.

Prioritizing interventions to manage polypharmacy in Australian aged care facilities.

BACKGROUND: Polypharmacy is highly prevalent in residential aged care facilities (RACFs). Although polypharmacy is sometimes unavoidable, polypharmacy has been associated with increased morbidity and mortality. OBJECTIVE: To identify and prioritize a range of potential interventions to manage polypharmacy in RACFs from the perspectives of health care professionals, health policy and consumer representatives. METHODS: Two nominal group technique (NGT) sessions were convened in August 2015. A purposive sample (n = 19) of clinicians, researchers, managers and representatives of consumer, professional and health policy organizations were asked to nominate interventions to address the prevalence and appropriateness of medication use. Participants were then asked to prioritize five interventions suitable for possible implementation at the system level. RESULTS: Six of 16 potential interventions were prioritized highest for possible implementation in clinical practice, with two interventions prioritized as second highest. The top interventions in rank order were 'implementation of a pharmacist-led medication reconciliation service for new residents,' 'conduct facility-level audits and feedback to staff and health care professionals,' 'develop deprescribing scripts to assist clinician-resident discussion,' 'develop or revise prescribing guidelines specific to older people with multimorbidity in RACFs,' 'implement electronic medication charts and records' and 'better support Medication Advisory Committees (MACs) to address medication appropriateness.' CONCLUSION: This study prioritized a range of potential interventions that may be used to assist clinicians and policy makers develop a comprehensive strategy to manage polypharmacy in RACFs.

Nicotine replacement therapy for agitation and delirium management in the intensive care unit: a systematic review of the literature.

BACKGROUND: Active smokers are prevalent within the intensive care setting and place a significant burden on healthcare systems. Nicotine withdrawal due to forced abstinence on admission may contribute to increased agitation and delirium in this patient group. The aim of this systematic review was to determine whether management of nicotine withdrawal, with nicotine replacement therapy (NRT), reduces agitation and delirium in critically ill patients admitted to the intensive care unit (ICU). METHODS: The following sources were used in this review: MEDLINE, EMBASE, and CINAHL Plus databases. Included studies reported delirium or agitation outcomes in current smokers, where NRT was used as management of nicotine withdrawal, in the intensive care setting. Studies were included regardless of design or number of participants. Data were extracted on ICU classification; study design; population baseline characteristics; allocation and dose of NRT; agitation and delirium assessment methods; and the frequency of agitation, delirium, and psychotropic medication use. RESULTS: Six studies were included. NRT was mostly prescribed for smokers with heavier smoking histories. Three studies reported an association between increased agitation or delirium and NRT use; one study could not find any significant benefit or harm from NRT use; and two described a reduction of symptomatic nicotine withdrawal. A lack of consistent and validated assessment measures, combined with limitations in the quality of reported data, contribute to conflicting results. CONCLUSIONS: Current evidence for the use of NRT in agitation and delirium management in the ICU is inconclusive. An evaluation of risk versus benefit on an individual patient basis should be considered when prescribing NRT. Further studies that consider prognostic balance, adjust for confounders, and employ validated assessment tools are urgently needed.

Development and validation of a 21-item challenges to stopping smoking (CSS-21) scale.

OBJECTIVE: Identification of challenges associated with quitting and overcoming them may improve cessation outcomes. This study describes the development and initial validation of a scale for measuring challenges to stopping smoking. METHODS: The item pool was generated from empirical and theoretical literature and existing scales, expert opinion and interviews with smokers and ex-smokers. The questionnaire was administered to smokers and recent quitters who participated in a hospital-based smoking cessation trial. Exploratory factor analysis was performed to identify subscales in the questionnaire. Internal consistency, validity and robustness of the subscales were evaluated. RESULTS: Of a total of 182 participants with a mean age of 55 years (SD 12.8), 128 (70.3%) were current smokers and 54 (29.7%) ex-smokers. Factor analysis of the 21-item questionnaire resulted in a 2-factor solution representing items measuring intrinsic (9 items) and extrinsic (12 items) challenges. This structure was stable in various analyses and the 2 factors accounted for 50.7% of the total variance of the polychoric correlations between the items. Internal consistency (Cronbach's α) coefficients for the intrinsic and extrinsic subscales were 0.86 and 0.82, respectively. Compared with ex-smokers, current smokers had a higher mean score (± SD) for intrinsic (24.0 ± 6.4 vs 20.5 ± 7.4, p=0.002) and extrinsic subscales (22.3 ± 7.5 vs 18.6 ± 6.0, p=0.001). CONCLUSIONS: Initial evaluation suggests that the 21-item challenges to stopping smoking scale is a valid and reliable instrument that can be used in research and clinical settings to assess challenges to stopping smoking.

Why is polypharmacy increasing in aged care facilities? The views of Australian health care professionals.

RATIONALE, AIMS AND OBJECTIVES: The prevalence of polypharmacy in residential aged care facilities (RACFs) is high and increasing. Although not necessarily inappropriate, polypharmacy has been associated with drug interactions, adverse drug events, geriatric syndromes and hospital admissions. The aim of this study was to identify and prioritize factors contributing to the increasing prevalence of polypharmacy in RACFs. METHODS: Seventeen health care professionals from metropolitan and regional Victoria and South Australia identified and prioritized factors using a modified nominal group technique. RESULTS: The top five factors ranked from most important to fifth most important were 'changes in resident mix', 'increasing numbers of prescribers and the reluctance of one prescriber to discontinue a medicine commenced by another prescriber', 'better adherence to clinical practice guidelines', 'increasing reliance on locums' and 'greater recognition and pharmacological management of pain'. CONCLUSIONS: Reasons for the increase in polypharmacy are multifactorial. Understanding the factors contributing to polypharmacy may help to guide future research and develop interventions to manage polypharmacy in RACFs.

Recommendations and Low-Technology Safety Solutions Following Neuromuscular Blocking Agent Incidents.

BACKGROUND: Neuromuscular blocking agents (NMBs) are high-risk medications used to facilitate endotracheal intubation and artificial ventilation. In an incident at a metropolitan tertiary referral and teaching public hospital in Australia, a neurosurgical patient became unresponsive at the start of surgery. It was determined that cisatracurium was administered in error in place of midazolam; the patient was ventilated and the emergency surgery continued. Two additional non-operating room (OR) drug-swap cases involving cisatracurium were reported within 12 months of this event, resulting in a comprehensive review of NMB safety. METHODS: A root cause analysis (RCA) resulted in multiple interventions to decrease the risk of selection and administration errors: (1) review of NMB packaging and introduction of in-house NMB labeling by pharmacy procurement staff before distribution; (2) implementation of a medication administration in anesthetics guideline with ongoing education; (3) audit of storage with removal of NMBs; (4) review of new products by medication safety pharmacists and a senior anesthetist before distribution; and (5) use of red-barrel syringes for administering NMBs was expanded to all areas using NMBs to minimize syringe-swap incidents. RESULTS: In the four years since full implementation of interventions, there have been no reports of cisatracurum selection errors. An incident of atracurium administration resulted in further recommendations for review of OR cart storage. Ongoing monitoring via medication safety walkrounds, by OR staff, by the perioperative pharmacist, and through the hospital's medication incident monitoring system has not detected any further NMB incidents. CONCLUSIONS: Technological solutions have been shown to decrease the risk of NMB errors, yet multifaceted low-technology solutions may be an effective, cheaper alternative.

Quitting experiences and preferences for a future quit attempt: a study among inpatient smokers.

OBJECTIVE: Understanding smokers' quit experiences and their preferences for a future quit attempt may aid in the development of effective cessation treatments. The aims of this study were to measure tobacco use behaviour; previous quit attempts and outcomes; methods used to assist quitting; difficulties experienced during previous attempts; the motives and preferred methods to assist quitting in a future attempt; identify the factors associated with preferences for smoking cessation. DESIGN: Face-to-face interview using a structured questionnaire. SETTING: Inpatient wards of three Australian public hospitals. PARTICIPANTS: Hospitalised smokers enrolled in a smoking cessation trial. RESULTS: Of 600 enrolled patients (42.8% participation rate), 64.3% (n=386) had attempted quitting in the previous 12 months. On a scale of 1 (low) to 10 (high), current motivation to quit smoking was high (median 9; IQR 6.5-10), but confidence was modest (median 5; IQR 3-8). Among 386 participants who reported past quit attempts, 69.9% (n=270) had used at least one cessation aid to assist quitting. Nicotine replacement therapy (NRT) was most commonly stated (222, 57.5%), although the majority had used NRT for <4 weeks. Hypnotherapy was the most common (68, 17.6%) non-pharmacological treatment. Over 80% (n=311) experienced withdrawal symptoms; craving and irritability were commonly reported. Most participants (351, 58.5%) believed medications, especially NRT (322, 53.7%), would assist them to quit in the future. History of previous smoking cessation medication use was the only independent predictor of interest in using medications for a future quit attempt. CONCLUSIONS: The majority of smokers had attempted quitting in the previous 12 months; NRT was a popular cessation treatment, although it was not used as recommended by most. This suggests a need for assistance in the selection and optimal use of cessation aids for hospitalised smokers.

Prevalence and factors associated with polypharmacy in long-term care facilities: a systematic review.

OBJECTIVE: The objective of the study was to investigate the prevalence of, and factors associated with, polypharmacy in long-term care facilities (LTCFs). METHODS: MEDLINE, EMBASE, International Pharmaceutical Abstracts, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library were searched from January 2000 to September 2014. Primary research studies in English were eligible for inclusion if they fulfilled the following criteria: (1) polypharmacy was quantitatively defined, (2) the prevalence of polypharmacy was reported or could be extracted from tables or figures, and (3) the study was conducted in a LTCF. Methodological quality was assessed using an adapted version of the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS: Forty-four studies met the inclusion criteria and were included. Polypharmacy was most often defined as 5 or more (n = 11 studies), 9 (n = 13), or 10 (n = 11) medications. Prevalence varied widely between studies, with up to 91%, 74%, and 65% of residents taking more than 5, 9, and 10 medications, respectively. Seven studies performed multivariate analyses for factors associated with polypharmacy. Positive associations were found for recent hospital discharge (n = 2 studies), number of prescribers (n = 2), and comorbidity including circulatory diseases (n = 3), endocrine and metabolic disorders (n = 3), and neurological motor dysfunctioning (n = 3). Older age (n = 5), cognitive impairment (n = 3), disability in activities of daily living (n = 3), and length of stay in the LTCF (n = 3) were inversely associated with polypharmacy. CONCLUSIONS: The prevalence of polypharmacy in LTCFs is high, varying widely between facilities, geographical locations and the definitions used. Greater use of multivariate analysis to investigate factors associated with polypharmacy across a range of settings is required. Longitudinal research is needed to explore how polypharmacy has evolved over time.

Pulmonary and systemic pharmacokinetics of inhaled and intravenous colistin methanesulfonate in cystic fibrosis patients: targeting advantage of inhalational administration.

The purpose of this study was to define the pulmonary and systemic pharmacokinetics of colistin methanesulfonate (CMS) and formed colistin following intravenous (i.v.) and inhaled administration in cystic fibrosis (CF) patients. Six CF subjects were administered nebulized CMS doses of 2 and 4 million IU and an i.v. CMS infusion of 150 mg of colistin base activity. Blood plasma, sputum, and urine samples were collected for 12 to 24 h postdose. To assess the tolerability of the drug, lung function tests, blood serum creatinine concentrations, and adverse effect reports were recorded. All doses were well tolerated in the subjects. The pharmacokinetic parameters for CMS following i.v. delivery were consistent with previously reported values. Sputum concentrations of formed colistin were maintained at <1.0 mg/liter for 12 h postdose. Nebulization of CMS resulted in relatively high sputum concentrations of CMS and formed colistin compared to those resulting from i.v. administration. The systemic availability of CMS was low following nebulization of 2 and 4 million IU (7.93% ± 4.26% and 5.37% ± 1.36%, respectively), and the plasma colistin concentrations were below the limit of quantification. Less than 2 to 3% of the nebulized CMS dose was recovered in the urine samples in 24 h. The therapeutic availability and drug targeting index for CMS and colistin following inhalation compared to i.v. delivery were significantly greater than 1. Inhalation of CMS is an effective means of targeting CMS and formed colistin for delivery to the lungs, as high lung exposure and minimal systemic exposure were achieved in CF subjects.

Improving the transition of highly complex patients into the community: impact of a pharmacist in an allogeneic stem cell transplant (SCT) outpatient clinic.

PURPOSE: Patients having undergone allogeneic stem cell transplantation (SCT) require complex medication regimens. To ensure the safe and effective management of this patient group, specialised care in a centre with a dedicated and experienced healthcare team is essential. The aim of this study was to evaluate the effectiveness of a specialty clinical pharmacist working in an ambulatory SCT clinic. METHODS: A prospective cohort study was conducted on patients post SCT and discharged to the ambulatory setting. Patients were reviewed by a clinical pharmacist weekly for six visits. At these visits a medication review was undertaken. Interventions from these reviews were recorded. Interventions were then assigned a risk rating by a multidisciplinary panel. Adherence was also assessed by a Morisky questionnaire and review of dose administration aids. Comparison of data over the six-visit period was undertaken. RESULTS: In total 23 patients were enrolled in the study. All six visits were completed in 17 patients and 161 interventions were recorded at an average of 1.4 interventions per patient visit. The panel rated 40 % of interventions as high risk, 46 % as medium risk and 14 % as low risk. At all visit points high- and medium-risk interventions constituted >80 % of the total. Morisky scores improved by an average of 1.53 (p < 0.0001) between visits 1 and 6. All patients were scored as highly adherent by visit 6. CONCLUSIONS: A specialist clinical pharmacist in the SCT outpatient clinic resulted in regular and effective intervention contributing to improved medication management and adherence.

A pharmacist-led system-change smoking cessation intervention for smokers admitted to Australian public hospitals (GIVE UP FOR GOOD): study protocol for a randomised controlled trial.

BACKGROUND: Intensive smoking cessation interventions initiated during hospitalisation are effective, but currently not widely available. Strategies are needed to integrate smoking cessation treatment into routine inpatient care. Pharmacist-led interventions for smoking cessation are feasible and efficacious in both ambulatory and community pharmacy settings. However, there is a lack of evidence from large scale studies of the effectiveness of pharmacist guided programs initiated during patient hospitalisation in achieving long-term abstinence. This study aims to evaluate the effectiveness of a pharmacist-led system change intervention initiated during hospitalisation in Australian public hospitals. METHODS/DESIGN: A multi-centre, randomised controlled trial will be conducted with 12 months follow-up. Smokers, 18 years or older, will be recruited from the wards of three Victorian public hospitals. Participants will be randomly assigned to a usual care or intervention group using a computer generated randomisation list. The intervention group will receive at least three smoking cessation support sessions by a trained pharmacist: the first during the hospital stay, the second on or immediately after discharge and the third within one month post-discharge. All smoking cessation medications will be provided free of charge during the hospital stay and for at least one week after discharge. Participants randomised to usual care will receive the current care routinely provided by the hospital.
