Medication discontinuity errors in the perioperative period

Interventions and impact of pharmacist-delivered services in perioperative setting on clinically important outcomes: a systematic review and meta-analysis

Background

The perioperative arena is a unique and challenging environment that requires coordination of the complex processes and involvement of the entire care team. Pharmacists' scope of practice has been evolving to be patient-centered and to expand to variety of settings including perioperative settings.

Objectives

To critically appraise, synthesize, and present the available evidence of the characteristics and impact of pharmacist-led interventions on clinically important outcomes in the perioperative settings.

Design

A systematic review and meta-analysis.

Methods

We searched PubMed, Embase, and CINAHL from index inception to September 2023. Included studies compared the effectiveness of pharmacist-led interventions on clinically important outcomes (e.g. length of stay, readmission) compared to usual care in perioperative settings. Two independent reviewers extracted the data using the DEPICT-2 (Descriptive Elements of Pharmacist Intervention Characterization Tool) and undertook quality assessment using the Crowe Critical Appraisal (CCAT). A random-effect model was used to estimate the overall effect [odds ratio (OR) for dichotomous and standard mean difference (SMD) for continuous data] with 95% confidence intervals (CIs).

Results

Twenty-five studies were eligible, 20 (80%) had uncontrolled study design. Most interventions were multicomponent and continuous over the perioperative period. The intervention components included clinical pharmacy services (e.g. medication management/optimization, medication reconciliation, discharge counseling) and education of healthcare professionals. While some studies provided a minor description in regards to the intervention development and processes, only one study reported a theoretical underpinning to intervention development. Pooled analyses showed a significant impact of pharmacist care compared to usual care on length of stay (11 studies; SMD -0.09; 95% CI -0.49 to -0.15) and all-cause readmissions (8 studies; OR 0.60; 95% CI 0.39-0.91). The majority of included studies (n = 21; 84%) were of moderate quality.

Conclusion

Pharmacist-led interventions are effective at improving clinically important outcomes in the perioperative setting; however, most studies were of moderate quality. Studies lacked the utilization of theory to develop interventions; therefore, it is not clear whether theory-derived interventions are more effective than those without a theoretical element. Future research should prioritize the development and evaluation of multifaceted theory-informed pharmacist interventions that target the whole surgical care pathway.

Barriers to managing medications appropriately when patients have restrictions on oral intake

RATIONALE, AIMS, AND OBJECTIVES

Investigation of several serious adverse events in our organization highlighted that medications were managed inappropriately when patients have oral intake restrictions. The aim of this work was to identify the barriers to optimal medication management when patients have restrictions on their oral intake.

METHOD

Data were feedback and comments obtained between 2011 and 2014 from a hospital-wide quality assurance project. Data had not been purposefully collected and were in response to a general request for feedback regarding managing oral medications when patients have oral intake restrictions. Data came from a range of clinical staff and from various forums associated with the quality assurance project, including 37 presentations, 34 group meetings, and over 50 one-on-one meetings, as well as emails and other sources. Data were analysed using the thematic analysis approach. Data were coded inductively, and the domains of the Theoretical Domains Framework were used to categorize the data. Subthemes and themes were then developed.

RESULTS

Barriers could be broadly grouped into systems-level issues (organizational guidance and work environment) and the individual person-level issues (staff knowledge and beliefs). These barriers highlight the complexity of the medication management task. The lack of standardized guidance and consistent terminology regarding medication administration when patients have restrictions on oral intake, particularly when fasting or nil by mouth, were important systems factors, as were workflow issues and the "culture" of the environment in which staff practiced. Lack of knowledge about medication administration, social influences, and role interpretation were important individual person factors.

CONCLUSION

Systems- and individual person-level issues were significant contributors to inappropriate medication management when patients have oral intake restrictions. Many of the barriers may be addressed with systems approaches such as hospital-wide guidance that simplifies and standardize oral medication administration instructions, particularly regarding fasting and nil by mouth terminology.

Clinical Audit on the Practice of Documentation at Preanesthetic Evaluation in a Specialized University Hospital

Background:

Performing preanesthetic evaluation, documenting, and keeping readily accessible record are responsibilities of anesthetists. Documentation can improve overall patient outcome. It also has an irreplaceable role in medico-legal aspects. Documentation is one of the challenges of providing quality care.

Aim:

The aim of this study was to evaluate the quality of documentation practice during preanesthetic visits.

Materials and Methods:

This clinical audit was conducted in the University of Gondar Hospital. Predefined 22 practice quality indicators were prepared according to modified global quality index.

Statistical Analysis:

Descriptive statistics was performed using SPSS version 20.

Results:

A total of 122 preanesthetic evaluation tools (PAETs) were reviewed. None of PAETs found fully completed according to the indicators. Trends differ between elective and emergency conditions. Indicators with high completion rate (>90%) were signed a consent, medical history, history of medication, allergy, anesthesia and surgery, cardiopulmonary examination, airway examination, preoperative diagnosis, and planned procedure. Anesthetic plan, vital signs, a name, per-oral status, premedication, and age were found with below average (<50%) completion rate.

Conclusions:

Documentation practice during the preanesthetic visit was below the standard. Unclear instructions should be replaced with standardized contents. Providing regular trainings on clinical documentation for students and staffs, and introducing modern electronic-based documentation system and preanesthetic clinics may improve the practice.

A cross-sectional study of preoperative medication adherence and early postoperative recovery

STUDY OBJECTIVE

To quantify the impact of preoperative medication adherence on recovery length of stays and complication rates.

DESIGN

Cross-sectional analytical study.

SETTING

Postanesthetic care unit (PACU) of a single-center tertiary hospital.

PATIENTS

Surgical patients admitted for surgery at our institution over a 4-month period.

INTERVENTION

A data collection tool was used to collect demographic data, length of stay in recovery, prespecified conditions likely to impact on PACU recovery (chronic pain, insulin-dependent diabetes, epilepsy, hypertension, on a methadone program, and Parkinson disease), medication compliance, and complications in PACU.

MEASUREMENTS

Differences among categorical variables were assessed for significance using the χ² test; continuous parametric data were compared using a time to survival analysis via Kaplan-Meier estimates and Cox proportional hazard regressions to account for possible confounders.

MAIN RESULTS

Preoperative medication compliance for the prespecified conditions was 65.1%. Patients with a preoperative condition spent more time in the PACU compared to patients without a preoperative condition. Time in PACU was not significantly longer for patients who took their medications compared to those who failed to take their medications. Patients with multiple prespecified conditions were more likely to incur a postoperative complication compared to patients without a prespecified condition. Patients with preoperative hypertension and insulin-dependent diabetes incurred higher complication rates in PACU for medication nonadherence compared to medication adherence.

CONCLUSION

This study taken together with accruing evidence suggests that preoperative medication omission remains an ongoing issue that can influence complication rates in the PACU. Patients with preoperative conditions stay longer in PACU, and medication omission was associated with higher rates of certain postoperative complications in PACU. This identifies patients likely to require more interventions and greater recovery resources. Further research into the impact of medication omission on recovery parameters after discharge from the PACU is warranted.

Medication reconciliation for patients undergoing spinal surgery

PURPOSE

In recent years, a marked increase of spinal operations prompted a debate on quality issues. Besides obvious factors, such as the surgical technique, medication safety has been identified as one of the major risk factors for patients undergoing anesthesia and surgery. While the issue has already been addressed by hospital pharmacist and anesthesiologists, the prescription of correct medication remains within the surgeons' responsibility. We, therefore, investigated medication-related errors in spinal instrumentation patients and applied current medication reconciliation strategies.

METHODS

We performed a data survey on all patients undergoing spinal instrumentation in 2011. Risk factors for medication safety were identified and prioritized. Specific counter-measures were introduced in 2012 and evaluated in 2013.

RESULTS

147 patients were included in the 2011 and 162 in the 2013 survey. As top five risk factors we identified the preoperative stopping of medication, recording the medication history, prescription process of postoperative analgetics and anticoagulants and the medication list at discharge. Specific counter-measures included standardization of preparations, doses and the prescription process and improving access to this information (online and via a smartphone application). In elective patients, recording the medication histories was delegated to a hospital pharmacist and informative flyers and posters were used to integrate the patients themselves into the process. Counter-measures directed against the first four risk factors resulted in a significant reduction of medication errors. The last risk factor was targeted by instructing the responsible staff only, which proved to be a rather ineffective measure.

CONCLUSIONS

Medication safety could be significantly improved by implementation of counter-measures specific to the identified risk factors.

A systematic approach to the preoperative medical evaluation of adults

The number, age, and medical complexity of patients undergoing elective noncardiac surgery is rising worldwide. Internists, family physicians, and midlevel providers asked to perform preoperative medical evaluations. However, lack of consensus has led to wide variation in practice in what is included and addressed in these evaluations, and the efficacy of these assessments has been debated. The intended purpose of the evaluation seems to be universally accepted as aiming to assess and identify risks associated with the patient's comorbid medical conditions and the specific surgical procedure. The goal is to minimize those risks. Herein, we propose a systematic approach to the preoperative medical evaluation based on the best available evidence and expert opinion, with an emphasis on identifying all potentially pertinent patient- and surgery-specific risk factors.
