Effectiveness and Utility of Flowcharts on Learning in a Classroom Setting: A Mixed-Methods Study.

OBJECTIVE: Graphical representation of information organizes and promotes meaningful learning. As an example of graphical organizers, flowcharts can simplify and summarize complex information. The evidence of classroom use of flowcharts as an instructional tool is unclear. We investigated the effectiveness of flowcharts on student learning as an in-class instructional tool in a cardiovascular therapeutic course. Student experiences with the use and application of flowcharts were explored. METHODS: An explanatory sequential mixed-methods study was conducted with pharmacy students enrolled in an acute-care cardiovascular course from 2019-2021. The quantitative phase comprised a survey to determine flowchart effectiveness and a comparison of student performance in three content areas. The qualitative phase of the study used focused group interviews to understand student perceptions of flowchart use. RESULTS: Survey results indicated that using flowcharts improved understanding (110/128, 86%), integration of material (114/128, 89%), and overall knowledge (111/128, 87%). Student performance in the 3 content areas, shock, arrhythmia, and acute coronary syndrome were statistically significant with flowcharts implementation. Emerging themes from student interviews were (1) used as a medium for retention and recall, (2) used as a study tool, and (3) used as a decision-making framework. CONCLUSION: Flowcharts provide an alternative approach to teaching complex content, which allows students to organize and summarize information that promotes meaningful learning. The ease of implementation combined with the generalized nature of flowcharts makes it an effective graphical organizer that can be used across various disciplines.

The Performance of Freestyle Libre Pro Flash Continuous Glucose Monitoring in Hospitalized Patients Treated with an Intravenous Insulin Infusion for Acute Prednisolone-Induced Hyperglycemia.

Few studies have evaluated the performance of flash glucose monitoring in hospitalized patients requiring intravenous insulin therapy. In this prospective study, an intravenous insulin infusion was adjusted hourly using flash glucose monitoring in hospitalized adults with prednisolone-associated hyperglycemia. The difference in paired point of care (POC) and flash glucose measurements and risk of severe hyper- or hypoglycemia (assessed by Clarke error grid analysis) were assessed. Glucose concentration measured by flash glucose monitoring was lower than POC glucose (mean difference 1.5 mmol/L [27 mg/dL], p < 0.001); however, mean POC glucose was within the target range (9.1 ± 4.1 mmol/L [164 ± 72 mg/dL]) and 97.8% of glucose measurements were within Zone A and B on error grid analysis. Flash glucose monitoring could be used in combination with POC glucose monitoring to minimize the frequency of finger prick blood glucose levels in hospitalized patients prescribed an intravenous insulin infusion.

Tolerability and efficacy of sodium-glucose co-transporter-2 inhibitors in Australian Aboriginal and Torres Strait Islanders with type 2 diabetes mellitus: an observational study.

Sodium-glucose co-transporter-2 inhibitors (SGLT2i) have renal and cardiovascular benefits in addition to their glucose-lowering potential. Data on the efficacy and safety of SGLT2i in Australian Aboriginal and Torres-Strait Islanders are lacking. We conducted a single-centre retrospective study assessing the safety and effects on glycaemic control and albuminuria of SGLT2i in Aboriginal and Torres Strait Islander patients with type 2 diabetes mellitus.

Clinical determinants of insulin requirements during treatment of prednisolone-induced hyperglycaemia.

AIMS: The optimal treatment of prednisolone-associated hyperglycaemia is unclear, but guidelines recommend using a body weight-based daily insulin dose. This study evaluated how clinical variables were associated with insulin requirements in hospitalised patients with prednisolone-associated hyperglycaemia. METHODS: In this prospective study, fifty adult inpatients who were taking prednisolone ≥20 mg/day and experienced hyperglycaemia were prescribed a 24-h intravenous insulin infusion. The daily insulin dose required to attain a mean glucose of 8 mmol/L was calculated. The associations between daily insulin dose and clinical variables were assessed. RESULTS: The participants age was 69 ± 10 years, daily prednisolone dose was 34 ± 10 mg, HbA1c was 7.7 ± 2.0 % (61 ± 10 mmol/mol), 77 % had known type 2 diabetes and 30 % were female. In univariate analysis, weight was associated with daily insulin dose (r2 = 0.11, p = 0.024). A multivariate model comprising sex, HbA1c, a prior diagnosis of diabetes, diabetes treatment and weight explained nearly-two thirds of the variability in daily insulin dose (r2 = 0.65, p < 0.001). CONCLUSIONS: In patients with prednisolone-associated hyperglycaemia, calculating insulin doses based on sex, HbA1c, diabetes status and regular diabetes treatment and weight may improve glycaemic control compared to weight-based dosing.

A collaborative comparison of international pediatric diabetes registries.

BACKGROUND: An estimated 1.1 million children and adolescents aged under 20 years have type 1 diabetes worldwide. Principal investigators from seven well-established longitudinal pediatric diabetes registries and the SWEET initiative have come together to provide an international collaborative perspective and comparison of the registries. WORK FLOW: Information and data including registry characteristics, pediatric participant clinical characteristics, data availability and data completeness from the Australasian Diabetes Data Network (ADDN), Danish Registry of Childhood and Adolescent Diabetes (DanDiabKids), Diabetes prospective follow-up registry (DPV), Norwegian Childhood Diabetes Registry (NCDR), National Paediatric Diabetes Audit (NPDA), Swedish Childhood Diabetes Registry (Swediabkids), T1D Exchange Quality Improvement Collaborative (T1DX-QI), and the SWEET initiative was extracted up until 31 December 2020. REGISTRY OBJECTIVES AND OUTCOMES: The seven diabetes registries and the SWEET initiative collectively show data of more than 900 centers and around 100,000 pediatric patients, the majority with type 1 diabetes. All share the common objectives of monitoring treatment and longitudinal outcomes, promoting quality improvement and equality in diabetes care and enabling clinical research. All generate regular benchmark reports. Main differences were observed in the definition of the pediatric population, the inclusion of adults, documentation of CGM metrics and collection of raw data files as well as linkage to other data sources. The open benchmarking and access to regularly updated data may prove to be the most important contribution from registries. This study describes aspects of the registries to enable future collaborations and to encourage the development of new registries where they do not exist.

Barriers to digital health services among people living in areas of socioeconomic disadvantage: Research from hospital diabetes and antenatal clinics.

ISSUE ADDRESSED: We sought to examine barriers to access to, use of, and benefits from digital health services in an area of socioeconomic disadvantage of Adelaide, Australia. METHODS: We conducted waiting room surveys in two hospital diabetes clinics and one hospital antenatal clinic in South Australia, and follow-up telephone interviews with 20 patients. We examined the extent of access to, use of and benefits from digital health services, and what barriers people encountered. We undertook mixed methods, with quantitative descriptive analysis and qualitative analysis. RESULTS: Thirty-seven diabetes clinic patients (54% response rate) and 99 antenatal clinic patients (33% response rate) participated. Sixty-two percent of the patients with diabetes and 27% of antenatal clinic patients had never used digital health services. Seventeen percent of patients with diabetes and 30% of antenatal clinic patients were hesitant users, and 22% of patients with diabetes and 44% of antenatal clinic patients were confident users. Barriers included struggling to afford the technology or to stay connected and a lack of trust in online health information. Potential benefits included feeling more empowered and complementing face-to-face care. CONCLUSIONS: There are socioeconomic barriers to access, use of, and ability to benefit from digital health strategies that mean not everyone will be able to benefit from digital health services. SO WHAT?: As COVID-19 accelerates the shift towards digital health services, people experiencing socioeconomic disadvantage may be excluded. If barriers to access and use are not addressed, they will exacerbate already increasing health inequities.

Diabetic Ketoacidosis at Onset of Type 1 Diabetes and Long-term HbA1c in 7,961 Children and Young Adults in the Australasian Diabetes Data Network.

OBJECTIVE: The relationship between diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes and long-term glycemic control varies between studies. We aimed, firstly, to characterize the association of DKA and its severity with long-term HbA1c in a large contemporary cohort, and secondly, to identify other independent determinants of long-term HbA1c. RESEARCH DESIGN AND METHODS: Participants were 7,961 children and young adults diagnosed with type 1 diabetes by age 30 years from 2000 to 2019 and followed prospectively in the Australasian Diabetes Data Network (ADDN) until 31 December 2020. Linear mixed-effect models related variables to HbA1c. RESULTS: DKA at diagnosis was present in 2,647 participants (33.2%). Over a median 5.6 (interquartile range 3.2, 9.4) years of follow-up, participants with severe, but not moderate or mild, DKA at diagnosis had a higher mean HbA1c (+0.23%, 95% CI 0.11,0.28; [+2.5 mmol/mol, 95% CI 1.4,3.6]; P < 0.001) compared with those without DKA. Use of continuous subcutaneous insulin infusion (CSII) was independently associated with a lower HbA1c (-0.28%, 95% CI -0.31, -0.25; [-3.1 mmol/mol, 95% CI -3.4, -2.8]; P < 0.001) than multiple daily injections, and CSII use interacted with severe DKA to lower predicted HbA1c. Indigenous status was associated with higher HbA1c (+1.37%, 95% CI 1.15, 1.59; [+15.0 mmol/mol, 95% CI 12.6, 17.4]; P < 0.001), as was residing in postcodes of lower socioeconomic status (most vs. least disadvantaged quintile +0.43%, 95% CI 0.34, 0.52; [+4.7 mmol/mol, 95% CI 3.4, 5.6]; P < 0.001). CONCLUSIONS: Severe, but not mild or moderate, DKA at diagnosis was associated with a marginally higher HbA1c over time, an effect that was modified by use of CSII. Indigenous status and lower socioeconomic status were independently associated with higher long-term HbA1c.

Determinants of Cardiovascular Risk in 7000 Youth With Type 1 Diabetes in the Australasian Diabetes Data Network.

CONTEXT: Cardiovascular disease occurs prematurely in type 1 diabetes. The additional risk of overweight is not well characterized. OBJECTIVE: The primary aim was to measure the impact of body mass index (BMI) in youth with type 1 diabetes on cardiovascular risk factors. The secondary aim was to identify other determinants of cardiovascular risk. DESIGN: Observational longitudinal study of 7061 youth with type 1 diabetes followed for median 7.3 (interquartile range [IQR] 4-11) years over 41 (IQR 29-56) visits until March 2019. SETTING: 15 tertiary care diabetes centers in the Australasian Diabetes Data Network.Participants were aged 2 to 25 years at baseline, with at least 2 measurements of BMI and blood pressure. MAIN OUTCOME MEASURE: Standardized systolic and diastolic blood pressure scores and non-high-density lipoprotein (HDL) cholesterol were co-primary outcomes. Urinary albumin/creatinine ratio was the secondary outcome. RESULTS: BMI z-score related independently to standardized blood pressure z- scores and non-HDL cholesterol. An increase in 1 BMI z-score related to an average increase in systolic/diastolic blood pressure of 3.8/1.4 mmHg and an increase in non-HDL cholesterol (coefficient + 0.16 mmol/L, 95% confidence interval [CI], 0.13-0.18; P < 0.001) and in low-density lipoprotein (LDL) cholesterol. Females had higher blood pressure z-scores, higher non-HDL and LDL cholesterol, and higher urinary albumin/creatinine than males. Indigenous youth had markedly higher urinary albumin/creatinine (coefficient + 2.15 mg/mmol, 95% CI, 1.27-3.03; P < 0.001) and higher non-HDL cholesterol than non-Indigenous youth. Continuous subcutaneous insulin infusion was associated independently with lower non-HDL cholesterol and lower urinary albumin/creatinine. CONCLUSIONS: BMI had a modest independent effect on cardiovascular risk. Females and Indigenous Australians in particular had a more adverse risk profile.

Use of Propofol Plus Dexmedetomidine in Patients Experiencing Severe Alcohol Withdrawal in the Intensive Care Unit.

Alcohol abuse and alcohol withdrawal syndrome are major problems in the United States. This retrospective chart review assessed efficacy and safety of propofol plus dexmedetomidine used in combination as adjunctive therapy to benzodiazepines compared with either agent used alone in the treatment of severe alcohol withdrawal. Patients admitted to the intensive care unit and experiencing severe alcohol withdrawal between September 1, 2015 and September 30, 2018 were assessed for eligibility. Primary end points were change in the revised Clinical Institute Withdrawal Assessment for Alcohol scale (CIWA-Ar) score and incidence of bradycardia and hypotension. The combination of propofol and dexmedetomidine was associated with a change in CIWA-Ar score of -10.4 (95%CI -13.5 to -7.3) points compared with -4.7 (95%CI -6.6 to -2.8) points with propofol and -4.4 (95%CI -7.4 to -1.4) with dexmedetomidine (P = .21). Bradycardia was experienced by 11.1% of patients receiving the combination, 15.4% of patients receiving propofol, and 28.6% of patients receiving dexmedetomidine (P = .40). Patients receiving dexmedetomidine experienced hypotension at a rate of 21.4% compared with 22.2% of patients receiving the combination and 38.5% of patients receiving propofol (P = .08). Patients in the combination group also had a shorter length of hospital and intensive care unit stay and shorter time to extubation when compared with the propofol and dexmedetomidine groups. Although no statistical significance was found, the combination was associated with better efficacy and safety outcomes than produced by either agent used alone.

Impact of an ambulatory care pharmacist in an occupational health clinic.

OBJECTIVES: To describe and evaluate a novel practice setting for a pharmacist within an occupational health clinic. SETTING: Ambulatory care facility. PRACTICE DESCRIPTION: Implementation and evaluation of a new practice site embedding a clinical pharmacist into the workplace to provide ambulatory care services, such as comprehensive medication management, disease state management, and immunizations to a broad diversity of patients. PRACTICE INNOVATION: A clinical pharmacist provides pharmacy services as part of a collaborative occupational health clinic at a large, self-insured company. The pharmacy services are open to employees and family members with any chronic disease states, elevated biometric results, or medication questions, with the goal of improving patient care on a consistent basis. During visits, the pharmacist works to identify and resolve drug-related problems by educating the patient or reaching out to the patient's health care provider and to develop strategies with the patient to achieve desired health care outcomes. The pharmacist assists with patient outreach events and immunizations during the flu clinic. EVALUATION: Identification of drug-related problems, resolution status, patient satisfaction via survey results, immunizations provided. RESULTS: In 4.3 years of operation, the pharmacist conducted 604 visits with 172 patients. During these visits, the pharmacist identified 611 drug-related problems, of which 49.4% have been confirmed as resolved. All patients who completed the patient satisfaction survey said that they would recommend the pharmacy services to others. For the past 3 years, the pharmacist and pharmacy students immunized approximately 1000 patients each year during the company flu clinic. CONCLUSION: An occupational health clinic is a unique and convenient location for a pharmacist to provide ambulatory care services to employees and family members, as long as methods to identify patients and appropriate sources of referral exist. The pharmacist was able to help patients resolve approximately 50% of identified drug-related problems, and patients were highly satisfied with services provided.

Essential Training, Resources, and Skills of First-Year and Junior Pharmacy Practice Faculty Needed in the Development of an Individual Research Program.

OBJECTIVE: To describe types of current training/support received and elicit opinions on the level of importance of specific skills and resources needed to build confidence in conducting research for early-career pharmacy practice faculty. METHODS: A survey instrument regarding available resources, levels of importance of resources, and skills needed to improve research confidence was sent to all new early-career practice faculty members with 3 or less years of experience in academia at 129 US colleges and schools of pharmacy. RESULTS: Few respondents indicated a formal research training existed at their institution. Overall, a majority of respondents identified at least 14 specific developmental areas as moderately to very important in building confidence. Over 75% of respondents rated 15 basic skills as moderately to very important in successfully starting an individual research program. CONCLUSION: Although different types of research training programs are available, confidence in conducting research in both informal and formal ones is low. Both groups of respondents identified similar important developmental research areas that would increase their confidence and skills in achieving their early research goals.

Practice Patterns and Opinions on Current Clinical Practice Guidelines Regarding the Management of Delirium in the Intensive Care Unit.

OBJECTIVE: The aim of this study was to determine current delirium practices in the intensive care unit (ICU) setting and evaluate awareness and adoption of the 2013 Pain, Agitation, and Delirium (PAD) guidelines with emphasis on delirium management. DESIGN, SETTING, AND PARTICIPANTS: A large-scale, multidisciplinary, online survey was administered to physician, pharmacist, nurse, and mid-level practitioner members of the Society of Critical Care Medicine (SCCM) between September 2014 and October 2014. A total of 635 respondents completed the survey. MEASUREMENTS AND MAIN RESULTS: Nonpharmacologic interventions such as early mobilization were used in most ICUs (83%) for prevention of delirium. A majority of respondents (97%) reported using pharmacologic agents to treat hyperactive delirium. Ninety percent of the respondents answered that they were aware of the 2013 PAD guidelines, and 75% of respondents felt that their delirium practices have been changed as a result of the new guidelines. In addition, logistic regression analysis of this study showed that respondents who use delirium screening tools were twice more likely to be fully aware of key components of the updated guidelines (odds ratio [OR] = 2.07, 95% confidence interval [CI] = 1.20-3.60). CONCLUSIONS: Most critical care practitioners are fully aware and knowledgeable of key recommendations in the new guidelines and have changed their delirium practices accordingly.

Treatment of prednisolone-induced hyperglycaemia in hospitalized patients: Insights from a randomized, controlled study.

AIM: Prednisolone causes hyperglycaemia predominantly between midday and midnight. Consequently, glargine-based basal-bolus insulin regimens may under treat daytime hyperglycaemia and cause nocturnal hypoglycaemia. We investigated whether an isophane-based insulin regimen is safer and more effective than a glargine-based regimen in hospitalized patients. MATERIALS AND METHODS: Fifty inpatients prescribed ≥20 mg/day prednisolone acutely with (1) finger prick blood glucose level (BGL) ≥15 mmol/L or (2) BGLs ≥10 mmol/L within the previous 24 hours were randomized to either insulin isophane or glargine before breakfast and insulin aspart before meals. The initial daily insulin dose was 0.5 U/kg bodyweight or 130% of the current daily insulin dose. Glycaemic control was assessed using a continuous glucose monitoring system. RESULTS: On Day 1, there were no significant differences in percentage of time outside a target glucose range of 4 to 10 mmol/L (41.3% ± 5.5% vs 50.0% ± 5.7%, P = .28), mean daily glucose (10.2 ± 0.7 vs 10.8 ± 0.8 mmol/L, P = .57) or glucose <4 mmol/L (2.2% ± 1.1% vs 2.0% ± 1.3%, P = .92) in patients randomized to isophane and glargine. In patients treated for 3 days, the prednisolone dose was reduced ( P = .02) and the insulin dose was increased over time ( P = .02), but the percentage of time outside the 4 to 10 mmol/L glucose range did not differ over time ( P = .45) or between groups ( P = .24). CONCLUSIONS: There were no differences in the efficacy or safety of the isophane and glargine-based insulin regimens. We recommend an initial daily insulin dose of 0.5 units/kg bodyweight if not on insulin, a greater than 30% increase in pre-prednisolone insulin dose and larger insulin dose adjustments in patients with prednisolone-induced hyperglycaemia.

Role of dexmedetomidine for the prevention and treatment of delirium in intensive care unit patients.

OBJECTIVE: To review recent clinical studies regarding the role of dexmedetomidine for prevention and treatment of delirium in intensive care unit (ICU) patients. DATA SOURCES: MEDLINE and PubMed searches (1988-Feburary 2013) were conducted, using the key words delirium, dexmedetomidine, Precedex, agitation, α-2 agonists, critical care, and intensive care. References from relevant articles were reviewed for additional information. STUDY SELECTION AND DATA EXTRACTION: Clinical trials comparing dexmedetomidine with other sedatives/analgesics or with antipsychotics for delirium were selected. Studies that evaluated the use of dexmedetomidine for sedation for more than 6 hours were included in this review. DATA SYNTHESIS: Dexmedetomidine is a highly selective α-2 receptor agonist that provides sedation, anxiolysis, and modest analgesia with minimal respiratory depression. Its mechanism of action is unique compared with that of traditional sedatives because it does not act on γ-aminobutyric acid receptors. In addition, dexmedetomidine lacks anticholinergic activity and promotes a natural sleep pattern. These pharmacologic characteristics may explain the possible anti delirium effects of dexmedetomidine. Eight clinical trials, including 5 double-blind randomized trials, were reviewed to evaluate the impact of dexmedetomidine on ICU delirium. CONCLUSIONS: Currently available evidence suggests that dexmedetomidine is a promising agent, not only for prevention but also for treatment of ICU-associated delirium. However, larger, well-designed trials are warranted to define the role of dexmedetomidine in preventing and treating delirium in the ICU.

Cannabinoid hyperemesis syndrome.

BACKGROUND: The purpose of this review is to describe cannabinoid hyperemesis syndrome (CHS), which is thought to be induced by long-term cannabis use, and provide clinical pharmacists with information to manage the hyperemetic phase of CHS. METHOD: Published literature was searched and reviewed using PubMed. RESULTS: CHS is characterized by intractable nausea and vomiting without an obvious organic cause and associated learned compulsive hot water bathing behavior. Patients often seek care in the emergency department (ED) for symptomatic relief. CONCLUSION: CHS is potentially underrecognized and underdiagnosed in the ED, and it should be considered in the differential diagnosis in long-term cannabis use patients with CHS symptoms to avoid unnecessary extensive diagnostic workup including invasive radiologic imaging. Pharmacists have an important role in CHS recognition, education, and symptom management.

Tenofovir-associated acute and chronic kidney disease: a case of multiple drug interactions.

Tenofovir therapy in patients with human immunodeficiency virus (HIV) infection has been associated with acute renal failure (ARF) and Fanconi syndrome. In the past 2 years, we diagnosed tenofovir-associated ARF in 5 HIV-infected patients who were receiving tenofovir therapy and who had classic findings of acute tubular necrosis, and we compared findings for our patients with data on 22 patients described in the literature. The mean serum creatinine level increased from 0.9 to 3.9 mg/dL, and it decreased to 1.2 mg/dL during recovery. ARF resolved in 22 of 27 patients after discontinuation of tenofovir therapy. The most common drugs given with tenofovir were ritonavir or lopinavir-ritonavir (21 of 27 patients), atazanavir (5 of 27 patients), and didanosine (9 of 27 patients). Tenofovir-associated ARF manifests as acute tubular necrosis that may not resolve with tenofovir withdrawal. Tenofovir is associated with multiple drug interactions, leading to an increased risk of ARF. Frequent monitoring of renal function is warranted for any patient receiving these combinations.
