Decrease In Prescription Rates Research Articles

A Time Series Analysis Evaluating Antibiotic Prescription Rates in Long-Term Care during the COVID-19 Pandemic in Alberta and Ontario, Canada.

The COVID-19 pandemic affected access to care, and the associated public health measures influenced the transmission of other infectious diseases. The pandemic has dramatically changed antibiotic prescribing in the community. We aimed to determine the impact of the COVID-19 pandemic and the resulting control measures on oral antibiotic prescribing in long-term care facilities (LTCFs) in Alberta and Ontario, Canada using linked administrative data. Antibiotic prescription data were collected for LTCF residents 65 years and older in Alberta and Ontario from 1 January 2017 until 31 December 2020. Weekly prescription rates per 1000 residents, stratified by age, sex, antibiotic class, and selected individual agents, were calculated. Interrupted time series analyses using SARIMA models were performed to test for changes in antibiotic prescription rates after the start of the pandemic (1 March 2020). The average annual cohort size was 18,489 for Alberta and 96,614 for Ontario. A significant decrease in overall weekly prescription rates after the start of the pandemic compared to pre-pandemic was found in Alberta, but not in Ontario. Furthermore, a significant decrease in prescription rates was observed for antibiotics mainly used to treat respiratory tract infections: amoxicillin in both provinces (Alberta: −0.6 per 1000 LTCF residents decrease in weekly prescription rate, p = 0.006; Ontario: −0.8, p < 0.001); and doxycycline (−0.2, p = 0.005) and penicillin (−0.04, p = 0.014) in Ontario. In Ontario, azithromycin was prescribed at a significantly higher rate after the start of the pandemic (0.7 per 1000 LTCF residents increase in weekly prescription rate, p = 0.011). A decrease in prescription rates for antibiotics that are largely used to treat respiratory tract infections is in keeping with the lower observed rates for respiratory infections resulting from pandemic control measures. The results should be considered in the contexts of different LTCF systems and provincial public health responses to the pandemic.

An audit comparing management of patients with HFrEF at a DGH before and during the COVID-19 pandemic.

This audit compared the management of patients with heart failure with reduced ejection fraction (HFrEF) admitted to a district general hospital (DGH) during comparative eight month periods before and during the COVID-19 pandemic. The periods studied were from 1st February 2019 to 30th September 2019 and between the same dates in 2020. We investigated differences in mortality and patient characteristics (age, gender and new or prior diagnosis). For patients who survived to discharge and who were not referred to palliative care, we also investigated whether there were differences in rates of echocardiography and prescription of angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists and beta blockers. We found that the number of cases was lower during the pandemic and there was a lower mortality rate that was not statistically significant. There was a higher proportion of new cases (odds ratio [OR] 2.21, 95% confidence interval [CI] 1.24 to 3.94, p=0.008) and of female patients (OR 2.03, 95%CI 1.14 to 3.61, p=0.019). For survivors, there was a non-significant decrease in prescription rates for ACE inhibitors and angiotensin II receptor antagonists (81.6% vs. 71.4%, p=0.137) that was not seen for beta blockers. The length of stay was increased and there was also an increase in the interval between admission and echocardiography in patients who were newly diagnosed. Regardless of time period, the time before echocardiography was significantly associated with length of stay.

Pharmacoepidemiological analysis of routine management of heart failure patients in the Russian Federation. Part I

Aim. To assess the healthcare system costs for the management of patients with heart failure (HF) based on a retrospective analysis of primary medical documentation.Material and methods. We performed the analysis of outpatient records of 1000 patients, followed up for 1 year by a general practitioner or cardiologist in ambulatory clinic in 7 Russian regions. The study included men and women over 18 years of age with an established class II-IV HF and at least one hospitalization due to acute decompensated HF within 12-month follow-up.Results. The final analysis included 888 patients (men, 52,9%; women, 47,1%; mean age, 69 [61; 78] years). The preserved ejection fraction (EF) was detected in 47,86% of patients, mid-range — in 40,54%, reduced — in 11,6%. Only in 16% of patients, there was improved by 1 or more HF. Hypertension and coronary artery disease were predominant in etiology pattern of HF. Preserved EF was more often detected in women over 60 years of age, with HTN and obesity, as well as with HF with mid-range and reduced EF in men in the same age group. There was sufficient follow-up rate, but the extent examinations do not correspond to the recommended one. The prescription rate of renin-angiotensin-aldosterone system (RAAS) inhibitors corresponds to the recommended one, but there is a high frequency of prescribing angiotensin II receptor blockers (ARBs). The prescription rate of β-blockers and loop diuretics (mainly torasemide) increased in comparison with previous studies, while thiazide diuretics — decreased. In patients with reduced EF, the prescription rate of sacubitril/valsartan was only 14,7%, β-blockers — 83,3%, mineralocorticoid receptor antagonists (MCRA) — 72,5%. In patients with midrange EF, there was a sharp decrease in prescription rate of RAAS inhibitors, β-blockers, MCRA.Conclusion. The practical follow-up of patients with HF differs significantly from clinical guidelines. Due to inadequate pharmacotherapy, as well as insufficient noncompliance with the recommended extent of investigations, 1-year HF therapy does not lead to a pronounced improvement in the patients' class.

Evaluation of a Large Urban–Rural Outpatient Antibiotic Stewardship Program

Background: Judicious prescribing of antibiotics is necessary in addressing the crisis of emerging antibiotic resistance and reducing adverse events. Nearly half of antibiotic prescriptions in the outpatient setting are inappropriate, most for viral upper respiratory infections (URIs). Data outlining the misuse of antibiotics in the outpatient setting provide compelling evidence of the need for more rational use of antimicrobial agents beyond hospital settings. Objectives: We evaluated the effect of a behaviorally enhanced quality improvement (QI) intervention to reduce inappropriate antibiotic prescribing for viral URI in the ambulatory care clinics of a large quaternary care healthcare system serving an urban-rural population. Methods: The outpatient antibiotic stewardship program was implemented in January 2018 at 5 pilot sites. Interventions included identification of a site champion, educational sessions, sharing of clinic and individual provider data, and patient and provider educational materials. In addition, preclinic huddles and resident education sessions for internal medicine resident physicians were conducted with a display of public commitment to prescribe antibiotics appropriately. Site champions collaborated with onsite staff to ensure interventions were consistent with local workflows, policies, and standards. The primary outcome was defined as the provider-level antibiotic prescribing rate for acute URI, defined as patient visits with antibiotic-nonresponsive diagnoses without concomitant diagnostic codes to support antibiotic prescribing (see the public MITIGATE tool kit for a complete list). Results: In total, 116,122 antibiotic prescriptions were dispensed from April 2017 through December 2018 compared to the period from April 2017 to December 2017 during which 9,129 fewer prescriptions were ordered. Inappropriate antibiotic prescribing for viral URI for ambulatory clinic encounters (n ≥ 45,000 visits per month) declined from 14.3% to 7.6%. Academic hospital-based sites showed little seasonality trends and no statistically significant decrease in prescription rates (P = .5176). On the other hand, community-based sites showed strong seasonal fluctuations and a statistically significant decrease in prescription rates after intervention (P = .000189). Conclusions: A multifaceted behaviorally enhanced QI intervention to reduce inappropriate prescribing for URI in ambulatory care encounters at a large integrated health system was successful in reducing both inappropriate prescriptions for presumed viral URI as well as total antibiotic use. Findings suggest that implementing leadership roles, education sessions, and low resource behavioral nudging (peer comparison and public commitment) together can decrease excessive use of antibiotics by physicians. A Hawthorne effect may be an important component of these interventions. Future studies are needed in order to determine the optimal combination of behavioral interventions that are cost-effective in outpatient settings.Funding: NoneDisclosures: Larissa May reports receiving speaking honoraria from Cepheid, research grants from Roche, and consultancy fees from BioRad and Nabriva.

Potential Impact of Umbilical-Cord-Blood Procalcitonin-Based Algorithm on Antibiotics Exposure in Neonates With Suspected Early-Onset Sepsis

Context: The incidence of early-onset neonatal infection has greatly decreased, but a new diagnostic approach is needed to avoid overdiagnosis and overtreatment. The aim of this study was to assess the potential impact of an algorithm incorporating umbilical-cord-blood procalcitonin (PCT) level on neonatal antibiotics prescription rate as compared with current practice.Material and methods: We conducted a prospective study in three maternity wards in France. All term and preterm neonates with the usual risk factors for neonatal group B Streptococcus infection were eligible for umbilical-cord-blood PCT testing. We compared the proportion of neonates who were exposed early to antibiotics (before 6 days of life) to that of neonates for whom antibiotics prescription would be indicated according to the PCT-based algorithm.Results: Among the 3,080 neonates included, 1 neonate presented with certain infection and 38 neonates with probable infection. The global antibiotics prescription rate was 4.6% [95% confidence interval (CI), 4.1–5]. With the PCT-based algorithm, the potential decrease in prescription rate would be 1.8% (95% CI, 1.3–2.3), corresponding to a 39% (95% CI, 37.3–40.7) relative reduction in antibiotics exposure (p < 0.05).Conclusion: These results suggest that the umbilical-cord-blood PCT-based algorithm could significantly help the clinicians in their antibiotic prescription decision to decrease neonatal antibiotics exposure as compared with current practice. If validated in a larger interventional randomized study, this approach could help clinicians stratify the risk of early-onset neonatal infection and initiate early antibiotics treatment in newborns at high risk of infection while limiting the deleterious effects of useless prescriptions in non-infected newborns.

Reduction in antibiotic prescribing for respiratory tract infections in Swedish primary care- a retrospective study of electronic patient records.

BackgroundSwedish studies on antibiotic use in primary care have been based on one-week registrations of infections. In order to study adherence to guidelines, analyses based on large databases that provide information on diagnosis linked prescriptions, are needed. This study describes trends in management of infections in Swedish primary care particularly with regards to antibiotic prescribing and adherence to national guidelines.MethodsA descriptive study of Sweden’s largest database regarding diagnosis linked antibiotic prescription data, the Primary care Record of Infections in Sweden (PRIS), for the years 2008, 2010 and 2013.ResultsAlthough the consultation rate for all infections remained around 30% each year, antibiotic prescribing rates decreased significantly over the years from 53.7% in 2008, to 45.5% in 2010, to 38.6% in 2013 (p = .032). The antibiotic prescribing rate for respiratory tract infections (RTIs) decreased from 40.5% in 2008 to 24.9% in 2013 while those for urinary tract infections and skin and soft tissue infections were unchanged. For most RTI diagnoses there was a decrease in prescription rate from 2008 to 2013, particularly for the age group 0–6 years. Phenoxymethylpenicillin (PcV) was the antibiotic most often prescribed, followed by tetracycline. Tonsillitis and acute otitis media were the two RTI diagnoses with the highest number of prescriptions per 1000 patient years (PY). For these diagnoses an increase in adherence to national guidelines was seen, with regards to treatment frequency, choice of antibiotics and use of rapid antigen detection test. The frequency in antibiotic prescribing varied greatly between different Primary Healthcare Centres (PHCCs).ConclusionFalling numbers of consultations and decreased antibiotic prescription rates for RTIs have reduced the antibiotic use in Swedish primary care substantially. Overprescribing of antibiotics could still be suspected due to large variability in prescribing frequency, especially for acute bronchitis and sinusitis. Continuous evaluation of diagnosis linked prescribing data and feedback to doctors is essential in order to achieve a more prudent antibiotic use.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-2018-9) contains supplementary material, which is available to authorized users.

Impact of computerized physician order entry alerts on prescribing in older patients.

A computerized physician order entry (CPOE) system provides opportunity for real-time alerts to prescribers. Winthrop University Hospital began using CPOE in 2009. We sought to improve prescribing among older hospitalized patients by adding alerts to the CPOE system for potentially inappropriate medications. In January 2011, informational alerts were integrated into the CPOE system for selected high-risk medications: diphenhydramine, metoclopramide, and all antipsychotics. We evaluated the effect of these alerts on prescribing frequency by comparing the number of prescriptions during the second quarters of 2010 ("pre-alert") with the second quarters of 2011 through 2013 ("post-alert"). Prescribing patterns were evaluated through a pharmacy database of medication orders. Frequency of prescribing was adjusted for total discharges. A comparison was made to ages 18-64years, and comparing "as needed" vs standing orders. In the 65years of age and older group, there were significant reductions in prescription rates pre-alert vs post-alert for diphenhydramine (p<0.001) and metoclopramide (p<0.001). There was no decrease in prescription rates for antipsychotics in older patients (p=0.80). In the younger comparison group, no decreases in prescription rates for those drugs were observed. Our analysis is based on numbers of written prescriptions and not actual doses administered; therefore, no conclusions concerning the effect of these alerts on communication or documentation of risk/benefits of these medications can be ascertained. The data suggest that prescribing rates for drugs with the least efficacy and potential for harm and with alternative agents (i.e., diphenhydramine and metoclopramide) can be modified by CPOE alerts for older patients.
