The Impact of a Pharmacist-Led Intravenous to Oral Switch of Metronidazole: A Before-and-After Study. Antibiotics (Basel) 2022; 11:antibiotics11101303. [PMID: 36289961 PMCID: PMC9598063 DOI: 10.3390/antibiotics11101303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 09/20/2022] [Accepted: 09/21/2022] [Indexed: 11/17/2022] Open
Abstract
(1) Background. Intravenous (IV) to oral switch (IVOS) of antibiotics can reduce the length of hospitalisation, risk of IV catheter complications, and hospital costs. Pharmacists can play an instrumental role in implementing an IVOS initiative. The aim of this study is to evaluate the impact of pharmacist-led IVOS of metronidazole. (2) Method. This was an observational study conducted in a New Zealand hospital. During a 3-month intervention period, pharmacists identified patients receiving IV metronidazole; then initiated an IVOS for patients who met the criteria. The comparator groups were patients who were not switched by pharmacists in the post-intervention (post-IVOS) group, or patients treated with either IV or oral metronidazole prior to the intervention (pre-IVOS). Primary outcome measures were switch rate and duration of IV metronidazole treatment. Secondary outcome measures were readmission and/or repeat surgery within 90 days of discharge and the length of hospital stay. (3) Results. In total, 203 patients were included: 100 in the pre-IVOS and 103 in the post-IVOS groups. Pharmacists switched 63/93 (67.7%) of eligible patients to oral metronidazole in the post-IVOS period. Only 9/89 (10.1%) of IVOS eligible patients were switched in the pre-IVOS group. In the post-IVOS group, the mean duration of IV metronidazole treatment in patients switched by pharmacists was shorter than in those who were not switched by pharmacists (2.5 ± 2.8 days vs. 4.8 ± 5.9 days, p = 0.012). No significant difference was found in readmission or repeat surgery within 90 days of discharge for patients switched by pharmacists versus patients who were not switched by pharmacists. (4) Conclusion. Our data have demonstrated successful implementation of the hospital-approved pharmacist-led IVOS service.

Pharmacist-led education-based antimicrobial stewardship interventions and their effect on antimicrobial use in hospital inpatients: a systematic review and narrative synthesis. J Hosp Infect 2021; 115:93-116. [PMID: 34144096 DOI: 10.1016/j.jhin.2021.06.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 06/06/2021] [Accepted: 06/07/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Antimicrobial stewardship (AMS) programmes optimize antimicrobial use and address antimicrobial resistance. Pharmacists are often key agents of these programmes. The effectiveness of hospital-based AMS interventions when they are led by pharmacists, however, has not previously been reported. AIM To evaluate the effectiveness of pharmacist-led AMS interventions in improving antimicrobial use for hospital inpatients. METHODS Standard systematic review methods were used. The search strategies and databases used in a previous Cochrane review were applied. Studies that reported pharmacist-led AMS interventions were included. Narrative synthesis was used to report the findings. PRISMA guidelines were followed. FINDINGS From 6971 records retrieved and screened, 52 full-text articles were included. Most studies were undertaken in teaching hospitals (N = 45) and many were conducted in North America (N = 27). Most interventions targeted junior or ward physicians and lasted between one and six months. All studies evaluated educational interventions often in combination with other interventions and reported improvements 'in compliance with target AMS practice'. Greater compliance was achieved with multiple interventions. Pharmacist-led interventions reduced the duration of antimicrobial therapy without increasing mortality. No consistency of evidence was achieved in relation to interventions and reduced duration of hospital stay, nor infections due to antimicrobial resistance or occurrence of Clostridium difficile. CONCLUSION This is the first systematic review to evaluate the effectiveness of pharmacist-led AMS interventions in hospital inpatients. Education-based interventions were effective in increasing guideline compliance and reducing duration of antimicrobial therapy. Future hospital-based AMS programmes should consider the involvement of pharmacists to deliver and promote AMS interventions and programmes.

Abstract
BACKGROUND Antibiotic IV-to-oral (IV-PO) conversion is a key initiative of antimicrobial stewardship programs. Guidelines and education are commonly described interventions to promote IV-PO conversion; however, technological interventions may be more effective in changing practice. OBJECTIVE To determine the impact of a clinical decision support (CDS) tool on the adoption and sustainability of an antibiotic IV-PO conversion program at a community academic hospital. METHODS A quasi-experimental study consisting of 3 phases was conducted. During phase 1, the pre-intervention antibiotic IV-PO conversion rate was determined. During phase 2, the IV-PO conversion policy was updated, education was provided to pharmacists and physicians, and a post-intervention evaluation was conducted. During phase 3, a CDS tool was developed to generate real-time electronic alerts prompting pharmacists to assess antibiotic therapy, and post-intervention audits were performed 1 month, 3 months, and 15 months after implementation of the tool. Pantoprazole IV-PO conversion was assessed during each phase as a non-equivalent dependent variable. The primary outcome was the proportion of patients eligible for IV-PO conversion who were switched to oral therapy. RESULTS Of 332 patients receiving targeted IV antibiotic therapy during the overall study period, 122 (37%) met the criteria for IV-PO conversion. The phase 2 IV-PO conversion rate of 35% (9/26) was comparable to the pre-intervention rate of 29% (10/35) (p = 0.61). Implementation of the CDS tool significantly increased the conversion rate to 78% (14/18), an increase that was sustained at 3 months (71% [17/24]) and 15 months (74% [14/19]) after implementation (p < 0.05 for all comparisons with phases 1 and 2). Pantoprazole conversion rates were similar across all phases. CONCLUSIONS Implementation of the CDS tool was effective in improving and sustaining antibiotic IV-PO conversion rates and enhancing policy compliance beyond the effects of policy revision and education. Refinement of both the policy and the tool is warranted to maximize adoption of the IV-PO conversion program.

Abstract
OBJECTIVES To assess the effectiveness of a combined intervention on the timing and rate of switching from intravenous (IV) to oral antibiotic therapy. MATERIALS AND METHODS The study used a historically-controlled prospective intervention design. Interventions consisted of educating physicians, handing out pocket-sized cards and providing switch advice in the electronic patient record (EPR). All patients hospitalized at the surgery department who were treated with IV antibiotics for at least 24 h and who fulfilled the switch criteria within 72 h of IV treatment were included. Outcomes before and during the intervention were compared. RESULTS An early IV to oral switch took place in 35.4% (35/99) of the antibiotic courses in the baseline period and in 67.7% (42/62) of the antibiotic courses in the intervention period (odds ratio [OR] 3.84, 95% confidence interval [CI] 1.96-7.53). Duration of IV therapy was significantly reduced from 5 to 3 days (P<0.01). Length of hospitalization was reduced from 6 to 5 days (P<0.05). CONCLUSIONS The interventions were effective in promoting an early IV to oral antibiotic switch by shortening the length of IV therapy and hospital stay.

Abstract
Background Hospital antimicrobial stewardship programs (ASPs) aim to promote judicious use of antimicrobials to combat antimicrobial resistance. For ASPs to be developed, adopted, and implemented, an economic value assessment is essential. Few studies demonstrate the cost-effectiveness of ASPs. This systematic review aimed to evaluate the economic and clinical impact of ASPs. Methods An update to the Dik et al. systematic review (2000–2014) was conducted on EMBASE and Medline using PRISMA guidelines. The updated search was limited to primary research studies in English (30 September 2014–31 December 2017) that evaluated patient and/or economic outcomes after implementation of hospital ASPs including length of stay (LOS), antimicrobial use, and total (including operational and implementation) costs. Results One hundred forty-six studies meeting inclusion criteria were included. The majority of these studies were conducted within the last 5 years in North America (49%), Europe (25%), and Asia (14%), with few studies conducted in Africa (3%), South America (3%), and Australia (3%). Most studies were conducted in hospitals with 500–1000 beds and evaluated LOS and change in antibiotic expenditure, the majority of which showed a decrease in LOS (85%) and antibiotic expenditure (92%). The mean cost-savings varied by hospital size and region after implementation of ASPs. Average cost savings in US studies were $732 per patient (range: $2.50 to $2640), with similar trends exhibited in European studies. The key driver of cost savings was from reduction in LOS. Savings were higher among hospitals with comprehensive ASPs which included therapy review and antibiotic restrictions. Conclusions Our data indicates that hospital ASPs have significant value with beneficial clinical and economic impacts. More robust published data is required in terms of implementation, LOS, and overall costs so that decision-makers can make a stronger case for investing in ASPs, considering competing priorities. Such data on ASPs in lower- and middle-income countries is limited and requires urgent attention.

Abstract
Hospitalized patients initially on intravenous antibiotics can be safely switched to an oral equivalent within the third day of admission once clinical stability is established. This conversion has many advantages as fewer complications, less healthcare costs and earlier hospital discharge. The three types of intravenous to oral conversion include sequential, switch, and step-down therapy. The aim of the study was to evaluate the practice of switching from intravenous to oral antibiotics, its types and its impact on the clinical outcomes. This was a retrospective observational study conducted in three Lebanese hospitals over a period of six months. Adult inpatients on intravenous antibiotics for 2 days and more were eligible for study enrollment. Excluded were patients admitted to care or surgery units, or those with gastrointestinal diseases, infections that require prolonged course of parenteral therapy, or malignancies. The study showed that among 452 intravenous antibiotic courses from 356 patients who were eligible for conversion, only one third were switched and the others continued on intravenous antibiotics beyond day 3 (P <0.0001). The mean duration of intravenous therapy of converted patients was markedly shorter than the non-converted (P <0.0001) with no significant change in the mean length of stay. Fluoroquinolones and macrolides were the most commonly converted antibiotics. However, the sequential therapy was the major type of conversion practiced in this study. Based on the study findings, a significant proportion of patients can be considered for switch. This emphasizes an important gap in the field of conversion from intravenous to oral antibiotic therapy and the need for integration and reinforcement of the appropriate Antibiotic Stewardship Programs in hospitals.

Abstract
BACKGROUND We aimed to evaluate the impact of physicians' educational programs in the reduction of inappropriate intravenous lines in internal medicine. METHODS Fifty-six French internal medicine units were enrolled in a nationwide, prospective, blinded, randomized controlled trial. Forms describing the patients with an intravenous line and internal medicine department characteristics were filled out on 2 separate days in January and April 2007. Following the first visit, all units were randomly assigned to either a specific education program on the appropriate indications of an intravenous line, during February and March 2007, or no training (control group). The Investigators' Committee then blindly evaluated the clinical relevance of the intravenous line according to pre-established criteria. The primary outcome was the percentage of inappropriate intravenous lines. RESULTS During January 2007, intravenous lines were used in 475 (24.9%) of the 1910 hospitalized patients. Of these, 80 (16.8%) were considered inappropriate. In April 2007, 416 (22.8%) of the 1823 hospitalized patients received an intravenous line, which was considered in 10.2% (21/205) of patients managed by trained physicians, versus 16.6% (35/211) of patients in the control group (relative difference 39%; 95% confidence interval, -0.6-13.3; P = .05). Reduced intravenous administration of fluids, antibiotics, and analgesics accounted for the observed decrease. CONCLUSION The use of a simple education program reduced the rate of inappropriate intravenous lines by almost 40% in an internal medicine setting (NCT01633307).

Abstract
OBJECTIVE This study measured the impact of three interventions for physicians, in order to implement guidelines for sequential therapy (intravenous to oral conversion) with fluoroquinolones. SETTING A Belgian university hospital with 1,065 beds. Method The first intervention consisted of the hospital-wide publication of guidelines in the local drug letter towards all prescribers. The consumption of fluoroquinolones was measured by means of an interrupted time-series (ITS) analysis 21 months before (period A) and 24 months after publication (period B). The second intervention was an educational interactive session, by infectious disease specialists, to the medical staff of orthopaedics and endocrinology. The third intervention comprised a proactive conversion programme on the abdominal surgery, gastro-enterology and plastic surgery wards, where pharmacists attached a pre-printed note with a suggestion to switch to an oral treatment every time a patient met the criteria for switching. The second and third intervention took place 6 months after the first intervention. Fluoroquinolone treatments were evaluated during a 2 month period before (group 1) and after the introduction of the second (group 2) and third (group 3) intervention. MAIN OUTCOME MEASURE The monthly ratio of intravenous versus total fluoroquinolone consumption (daily defined doses per 1,000 bed days) was measured to assess the impact of the first intervention. The impact of the second and third intervention was measured in relation to the number of days that intravenous therapy continued beyond the day that the patient fulfilled the criteria for sequential therapy and the antibiotic cost. RESULTS The ITS demonstrated a reduction of 3.3% in the ratio of intravenous versus total consumption after the publication of the guidelines (P = 0.011). In group 1, patients were treated intravenously for 4.1 days longer than necessary. This parameter decreased in group 2 to 3.5 days and in group 3 to 1.0 day (P = 0.006). The mean additional cost for longer intravenous treatment decreased from 188.0 euro in group 1, to 103.0 euro in group 2 and 44.0 euro in group 3 (P = 0.037). CONCLUSION This study demonstrated that active implementation of guidelines is necessary. A proactive conversion programme by a pharmacist resulted in a reduction in the duration of the intravenous treatment, and the treatment cost.

Abstract
Objectives To evaluate outcomes following implementation of a checklist with criteria for switching from intravenous (iv) to oral antibiotics on unselected patients on two general medical wards. Methods During a 12 month intervention study, a printed checklist of criteria for switching on the third day of iv treatment was placed in the medical charts. The decision to switch was left to the discretion of the attending physician. Outcome parameters of a 4 month control phase before intervention were compared with the equivalent 4 month period during the intervention phase to control for seasonal confounding (before–after study; April to July of 2006 and 2007, respectively): 250 episodes (215 patients) during the intervention period were compared with the control group of 176 episodes (162 patients). The main outcome measure was the duration of iv therapy. Additionally, safety, adherence to the checklist, reasons against switching patients and antibiotic cost were analysed during the whole year of the intervention (n = 698 episodes). Results In 38% (246/646) of episodes of continued iv antibiotic therapy, patients met all criteria for switching to oral antibiotics on the third day, and 151/246 (61.4%) were switched. The number of days of iv antibiotic treatment were reduced by 19% (95% confidence interval 9%–29%, P = 0.001; 6.0–5.0 days in median) with no increase in complications. The main reasons against switching were persisting fever (41%, n = 187) and absence of clinical improvement (41%, n = 185). Conclusions On general medical wards, a checklist with bedside criteria for switching to oral antibiotics can shorten the duration of iv therapy without any negative effect on treatment outcome. The criteria were successfully applied to all patients on the wards, independently of the indication (empirical or directed treatment), the type of (presumed) infection, the underlying disease or the group of antibiotics being used.

Abstract
OBJECTIVE Intravenous-to-oral switch therapy is strongly recommended in the medical literature. The aim of this study was to assess how we can improve fluoroquinolone switch therapy. METHODS In this comparative prospective study, we analyzed 243 intravenous ciprofloxacin treatments and assessed the impact of promoting a switch to oral step-down therapy. RESULTS This study found that switches from intravenous to oral therapy increased, mainly in medical wards, and led to significant savings in direct costs. DISCUSSION Promoting switch therapy has improved clinical practices in antibiotic use and led to lower direct and probably indirect drug-related costs. CONCLUSION Our findings will help define the role of switch therapy in improving clinical practices in inpatient antibiotic use.

Abstract
AIM OF THE REVIEW To identify and review the clinical and economic impact of pharmacists' interventions on antibiotic use. METHOD A literature search was conducted on Medline (1966-2003) to identify original articles measuring the impact of pharmacists' interventions on antimicrobial therapy at patient's or prescriber's level. RESULTS Forty-three articles were included: 20 uncontrolled before-after studies, four controlled before-after studies, five controlled trials, 12 randomized controlled trials and two interrupted time series (ITS). The described interventions were grouped into four categories: patient-specific recommendations (pharmacists' interventions concerning patient-specific drug therapy), implementation of policies, education, and therapeutic drug monitoring. These interventions were often combined to provide a multifaceted intervention, making it difficult to isolate the impact of one specific intervention. Measured outcomes were: appropriateness of prescribing (evaluated in 17 studies, 16 showing significant improvement), costs (analysed in 22 studies, nine showing a statistically significant reduction in costs after or with the intervention), and length of hospital stay (mixed results). Other measured outcomes were: drug use, prescriptions, length of treatment, dose intervals, switch to oral route, mortality rate, and treatment failure. CONCLUSION Over the years, the number of studies and quality of methodology has increased. The most frequently observed outcomes with a positive impact were appropriateness of prescribing and cost savings. The vast majority of studies used multiple interventions, in conjunction with pharmacists' recommendations to physicians. Coupled with the use of practice guidelines or educational strategies, these interventions demonstrated a positive impact on economic or clinical outcomes. However, the data are still sparse and sometimes contradictory; therefore, further studies with randomized controlled designs are needed.

Abstract
BACKGROUND A high proportion of medical in-patients in the UK receive intravenous (IV) antibiotic therapy. This may be inappropriate in non-severe infections, or unnecessarily prolonged. AIM To assess the impact of guideline implementation on IV antibiotic prescribing in medical admissions to a general hospital. DESIGN Observational intervention study. METHODS Data relating to infection and antibiotic therapy were collected for 4 weeks pre-intervention (group 1) and 4 weeks post intervention (group 2). Six months later, data were collected for a further 4 weeks following a second intervention (group 3). Interventions consisted of pharmacy-led implementation of guidelines incorporating criteria for IV therapy and switching to the oral route. The second intervention also included pharmacy-initiated feedback on prescribing. The main outcome measures were IV antibiotic duration, and appropriateness of the IV route and switching. RESULTS Of 2365 admissions, 757 (32%) had 806 treated episodes. IV therapy was used in 40%, 46% and 36% (groups 1, 2 and 3, respectively) and was appropriate in 92% vs. 100% (group 1 vs. 2). In groups 2 and 3, oral switch timing was appropriate in 90% and 88%, vs. 17% in group 1 (p < 0.001). Between groups 1 and 2, median duration of IV therapy was reduced from 3 to 2 days (p = 0.01). More patients in group 2 received appropriate exclusively IV therapy (65% vs. 96%, p < 0.01). Duration of stay in IV-treated patients reduced from 13 to 10 days in groups 2 and 3 (p = 0.047). IV antibiotic expenditure reduced by 13% per patient admitted between groups 1 and 2. DISCUSSION Pharmacy-led introduction of antibiotic guidelines appears to result in clinically appropriate reductions in IV therapy.

The impact of a pharmacist-managed dosage form conversion service on ciprofloxacin usage at a major Canadian teaching hospital: a pre- and post-intervention study. BMC Health Serv Res 2005; 5:48.

Abstract
Background Despite cost containment efforts, parenteral (IV) ciprofloxacin appears to be overutilized at Vancouver General Hospital. In November 2003, the Pharmacist-managed intravenous to oral (IV-PO) Dosage Form Conversion Service was implemented, enabling autonomous pharmacist-initiated dosage form conversion for ciprofloxacin. This study evaluates characteristics of ciprofloxacin use prior to and following implementation of this conversion service. Methods This was a single-centre, two-phase (pre/post), unblinded study. Phase I occurred between November 12, 2002 and November 11, 2003 (365 days), and Phase II between November 12, 2003 and March 11, 2004 (120 days). All patients receiving ciprofloxacin IV during these periods were reviewed. The primary endpoint was IV:PO ciprofloxacin use ratio. Secondary endpoints were total number of ciprofloxacin doses, proportion of inappropriate IV ciprofloxacin doses, cost of therapy between phases, and estimated cost avoidance with the intervention. Results Two hundred ciprofloxacin IV treatment courses were evaluated (100 per phase). The IV:PO ciprofloxacin use ratio was 3.03 (Phase I) vs. 3.48 (Phase II). Total number of doses and ratio of IV to total doses across phases were similar (p = 0.2830). IV-PO ciprofloxacin conversion occurred in 27/100 (27%) of IV courses in Phase I and 23/100 (23%) in Phase II. Proportion of inappropriate ciprofloxacin IV doses decreased between Phases I and II (244/521 (47%) vs. 201/554 (36%) (p = 0.0005), respectively). Furthermore, the proportion of pharmacist-preventable inappropriate ciprofloxacin IV doses was reduced between Phases I and II (114/244 (47%) vs. 65/201 (32%) (p = 0.0026). Proportional cost avoidance associated with total inappropriate IV use was $7,172/$16,517 (43%) (in Canadian dollars) in Phase I vs. $6,012/$17,919 (34%) in Phase II (p = 0.001). Similarly, proportional cost avoidance associated with pharmacist-preventable inappropriate IV doses was reduced from $3,367/$16,517 (20%) in Phase I to $1,975/$17,919 (11%) in Phase II (p = 0.001). Conclusion While overall utilization of ciprofloxacin remained unchanged and the proportion of IV to total doses was stable during the study period, the proportion of inappropriate IV doses and its associated costs appear to have declined subsequent to implementation of a Pharmacist-managed IV-PO Dosage Form Conversion Service. Such a program may be a beneficial adjunct in facilitating appropriate and cost-effective usage of ciprofloxacin.

Abstract
OBJECTIVES Evaluation of the impact of the implementation of practice guidelines, with or without their reinforcement by a pharmacist, on the intra-hospital use of antibiotics. MATERIALS AND METHODS The duration of antibiotic treatment, their cost, and the length of patient stay were compared in three secondary-care hospitals, before and after interventions that were designed to promote rational antibiotic use. After randomization, hospital A received no intervention (control), local practice guidelines were implemented in hospital B (low grade intervention), and these guidelines were reinforced by a clinical pharmacist in hospital C (high grade intervention). Adherence to the guidelines was measured in hospitals B and C. Multivariable statistical analyses were carried out to adjust for confounding factors. RESULTS None of the outcomes measured in the 1200 included patients decreased between the two study periods in any hospital. Hospital A was significantly and independently associated with an increase in the duration of antibiotic treatments, the cost of antibiotics (acquisition and global costs), and the length of stay. Although these differences were not statistically significant, increases in hospital B were higher than in hospital C. Adherence to guidelines was significantly higher in hospital C. CONCLUSIONS Even though interdisciplinary interventions aiming at rationalizing antibiotic use could not diminish the duration of treatments, their costs or the length of stay, they proved useful to control the progression of these parameters.

Abstract
OBJECTIVE The cost of antibiotics in hospitals may be reduced by streamlining, and, particularly, by early switching from the intravenous (i.v.) to the oral route of administration. The aim of the study was to evaluate the feasibility and impact of guidelines for switching, reinforced by pharmacists. METHOD Patients admitted to internal medicine wards and treated with i.v. antibiotics for various infections were included for six weeks before (group A) and six weeks after (group B) the intervention. Differences in patient characteristics and their outcomes were sought between the two groups. RESULTS The 26 patients in group B stayed longer in hospital than the 29 in group A (13.3 vs. 9.7 days; P = 0.05). They also tended to need more time to reach the pre-defined criteria for switching (3.6 vs. 2.4 days; P = 0.09). From that point on, they were switched more rapidly to oral antibiotics (1.5 vs. 3.2 days; P = 0.02), which resulted in a trend toward a lower treatment cost until their discharge (44 vs. 92 euros; P = 0.08). No difference was found between the 2 groups for the duration of the i.v. therapy, or the total in-hospital cost of antibiotics. CONCLUSION Pharmacists may help implement and reinforce guidelines for switching to oral antibiotics. The evaluation of such interventions implies the choice of appropriate outcomes and the awareness of confounding factors.

Abstract
We sought to summarize and assess original evaluations of the economic impact of clinical pharmacy services published from 1996-2000, and to provide recommendations and methodologic considerations for future research. A systematic literature search was conducted to identify articles that were then blinded and randomly assigned to reviewers who confirmed inclusion and abstracted key information. Results were compared with those of a similar review of literature published from 1988-1995. In the 59 included articles, the studies were conducted across a variety of practice sites that consisted of hospitals (52%), community pharmacies and clinics (41%), health maintenance organizations (3%), and long-term or intermediate care facilities (3%). They focused on a broad range of clinical pharmacy services such as general pharmacotherapeutic monitoring (47%), target drug programs (20%), disease management programs (10%), and patient education or cognitive services (10%). Compared with the studies of the previous review, a greater proportion of evaluations were conducted in community pharmacies or clinics, and the types of services evaluated tended to be more comprehensive rather than specialized. Articles were categorized by type of evaluation: 36% were considered outcome analyses, 24% full economic analyses, 17% outcome descriptions, 15% cost and outcome descriptions, and 8% cost analyses. Compared with the studies of the previous review, a greater proportion of studies in the current review used more rigorous study designs. Most studies reported positive financial benefits of the clinical pharmacy service evaluated. In 16 studies, a benefit:cost ratio was reported by the authors or was able to be calculated by the reviewers (these ranged from 1.7:1-17.0:1, median 4.68:1). The body of literature from this 5-year period provides continued evidence of the economic benefit of clinical pharmacy services. Although the quality of study design has improved, whenever possible, future evaluations of this type should incorporate methodologies that will further enhance the strength of evidence of this literature and the conclusions that may be drawn from it.
