Effects of BuzzyⓇ and ShotBlockerⓇ on Pain and Anxiety During Immunization in Children: A Randomized Controlled Trial

OBJECTIVE

Childhood vaccines are a vital procedure for preventing infectious diseases and are a regular component of a child's medical care. However, vaccines are among the first and most frequently encountered painful procedures that can cause indicators of anxiety in relation to immunizations. This study aimed to identify and assess the impact of the ShotBlockerⓇ and BuzzyⓇ approaches on pain, anxiety and satisfaction with the tetanus-diphtheria vaccine in school-aged children.

DESIGN

An experimental randomized controlled trial.

METHODS

The study included a sample of 138 children aged 13-years-old receiving the tetanus-diphtheria vaccine at a family health clinic. Participants were randomly assigned to the ShotBlockerⓇ, BuzzyⓇ and control groups. Each group consisted of 46 children, with an equal distribution of 23 females and 23 males. Data were collected using the State-Trait Anxiety Inventory (state version) and Visual Analog Scale.

RESULTS

The ShotBlockerⓇ and BuzzyⓇ groups exhibited lower pain and anxiety scores than the control group. However, there was no statistically significant difference between groups (for pain, p = .135; for anxiety, p = .276). It was found though that there was a statistically significant difference between the mean anxiety scores of groups before and after vaccination (p < .001). Following vaccination, although the satisfaction scores of children in the ShotBlockerⓇ and BuzzyⓇ groups were higher, there was no statistically significant difference between the groups (p = .245).

CONCLUSIONS

The use of BuzzyⓇ and ShotBlockerⓇ has been demonstrated to be beneficial in reducing the pain and anxiety associated with tetanus-diphtheria vaccine injections in 13-year-old children. Furthermore, these methods can be employed frequently during vaccination to enhance children's satisfaction.

Effects of the Helfer skin tap technique and Buzzy® application on the levels of pain and fear experienced by children during vaccination: A randomized controlled trial

PURPOSE

Vaccination is an invasive procedure that causes pain. Uncontrolled pain negatively affects all aspects of life, including health. This study aimed to determine the effects of the Helfer skin tap technique and Buzzy® application on the levels of pain and fear experienced by 4-year-old children during measles-mumps-rubella (MMR) vaccination.

METHODS

This study adopted a randomized controlled experimental design. The study sample consisted of 96 children (Helfer skin tap technique group: n = 32, Buzzy® group: n = 32, control group: n = 32) who received MMR vaccination. Children in the Buzzy® and Helfer skin tap technique groups received their respective interventions before and after vaccine injection, while children in the control group received routine vaccine injection.

RESULTS

Based on the parents' and nurse's observations, the pain and fear scores after vaccine injection were lowest in the Buzzy® group and highest in the control group. Based on the children's assessments, the pain scores after vaccine injection were lower in the Buzzy® group than in the Helfer skin tap technique group.

CONCLUSION

Buzzy® application and the Helfer skin tap technique have beneficial effects on children's pain and fear during MMR vaccination. Buzzy® application is more effective in reducing pain and fear during vaccine injection in children than the Helfer skin tap technique.

PRACTICE IMPLICATIONS

Nurses can increase the comfort of children by reducing pain during vaccination using Buzzy®.

Comparison of the effect of intramuscular injection from two different sites on pain and fear in children: a randomized controlled study

OBJECTIVE

This study aims to compare vastus lateralis and ventrogluteal site utilizations concerning pain and fear in intramuscular injection in children between 4 and 6 years of age.

METHODS

A randomized trial design was utilized in this study. Groups were randomly assigned as ventrogluteal (n=43) and vastus lateralis (n=40). Children in both groups were compared before, during, and after the procedure using the Children's Fear Scale and the Wong-Baker Faces Pain Rating Scale. Crying time was measured using a stopwatch during the procedure.

RESULTS

While the mean Children's Fear Scale total scores of the children in the ventrogluteal group were similar before the procedure, the mean Children's Fear Scale total scores during and after the procedure were significantly lower than the children in the vastus lateralis group. Wong-Baker Faces Pain Rating Scale mean scores were significantly lower in the ventrogluteal group. The mean crying time of the children in the ventrogluteal group was significantly lesser than those in the vastus lateralis group (p=0.000).

CONCLUSION

The results of the study showed that the choice of the ventrogluteal site in intramuscular injection in children between 4 and 6 years of age was effective in reducing pain, fear, and crying time.

Temporal Dynamics of Pain: Examining the Relationship Between Intramuscular Injection Duration and Pain Perception: A Crossover Randomized Controlled Trial

Background Effective pain management is crucial for optimizing the patient experience and satisfaction with care. Many factors affect the intensity of injection pain, and one of these factors is the duration of the injection. This study aimed to evaluate the impact of intramuscular injection duration on perceived pain intensity in adults. Methods Fifty participants received injections according to a predetermined research protocol. Each participant served as their own control group. The intervention group was administered the drug over 40 seconds. The control group was given the same drug on the other side dorsogluteal region the following day, according to the unit's routine, in 10 seconds. Pain intensity was measured using the Wong-Baker Faces Pain Rating Scale and the Numerical Rating Scale. Statistical analysis was performed using SPSS (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp), including Wilcoxon and correlation analyses, with a significance level set at p < 0.05. Results The Wilcoxon test revealed a significant decrease in pain scores for the intervention group (p < 0.05), indicating that longer injection durations were associated with lower pain intensity. Significant correlations were found between hospital phobia and the use of pain relief measures, with pain perception (p < 0.05). Conclusion This research establishes a correlation between extended durations of intramuscular injections and pain intensity. These findings have implications for pain management during medical procedures and can contribute to optimizing patient comfort.

Effects of ShotBlocker® and the Helfer skin tap technique on pain and fear experienced during intramuscular injection among children aged 6-12 years in pediatric emergency units: A randomized controlled trial

BACKGROUND

In pediatric emergency units, intramuscular injection is one of the most common procedures that cause pain and fear in children. Reducing pain and fear is important for patient comfort.

OBJECTIVE

This randomized controlled experimental study aimed to determine the effects of ShotBlocker® and the Helfer skin tap technique on the pain and fear experienced by children aged 6-12 years during intramuscular injection in pediatric emergency units.

METHODS

This study was conducted from April 2022 to October 2023 among 177 children aged 6-12 years. ShotBlocker and the Helfer skin tap technique were applied during intramuscular injection among children in the intervention groups (ShotBlocker group: n = 59, Helfer skin tap technique group: n = 59), while children in the control group received routine injections. (n = 59). The levels of pain and fear were measured.

RESULTS

In the analysis of the age distribution of the children, the average age of the Helfer skin tap technique group was found to be 8.54 ± 2.00 years; ShotBlocker group, 8.46 ± 1.99 years; and control group, 9.19 ± 2.01 years. There was a significant difference in the post-intervention Wong-Baker Pain Scale and Child Fear Scale scores based on the evaluation of the children, parents, and observer nurses between the groups (p < 0.05). The pain and fear scores of the ShotBlocker group were lower than those of the control group (p < 0.05).

CONCLUSIONS

ShotBlocker is more effective in reducing pain than the Helfer skin tap technique among children receiving intramuscular injection. These cheap and easy-to-use methods are recommended for use in emergency units.

Comparison of Pain With Ultrasound-Guided Intra-Articular Hip Injections With and Without Prior Subcutaneous Local Anesthesia

OBJECTIVE

To compare pain levels of intra-articular hip steroid injections performed with and without prior subcutaneous local anesthesia (LA) injection.

DESIGN

Randomized prospective study.

SETTING

University-based musculoskeletal clinic.

PARTICIPANTS

Forty-one adult patients undergoing a first-time ultrasound-guided unilateral intra-articular hip steroid injection.

INTERVENTIONS

Subjects were randomized into 1 of 2 groups: intra-articular hip injection with prior subcutaneous LA with 2 mL of lidocaine 1% (With LA) or hip injection without prior subcutaneous LA (Without LA). Visual analog scale (VAS) pain scores (0-100) were collected before and after each injection.

MAIN OUTCOME MEASURES

Visual analog scale pain score for the intra-articular hip injection.

RESULTS

Of the 41 total subjects, 18 were randomized to the Without LA group and 23 to the With LA group. There was no significant difference in baseline (preprocedure) VAS scores between the Without LA (mean ± SD = 39.2 ± 27.2) and With LA (41.2 ± 24.0) groups (P = 0.864). The mean ± SD VAS score for the subcutaneous LA injection in the With LA group was 20.4 ± 16.1. There was no significant difference in VAS scores for the intra-articular hip injection between the Without LA (48.5 ± 27.7) and With LA (39.5 ± 25.7) groups (P = 0.232).

CONCLUSIONS

Subcutaneous injection of lidocaine before an intra-articular hip injection did not significantly decrease pain from the intra-articular hip injection. Providers may perform intra-articular hip injections with a 22-gauge 3.5-inch spinal needle without the need for an extra subcutaneous LA injection.

Cabotegravir + Rilpivirine Long-Acting: Overview of Injection Guidance, Injection Site Reactions, and Best Practices for Intramuscular Injection Administration

Background

Cabotegravir (CAB) + rilpivirine (RPV) dosed monthly or every 2 months is a complete long-acting (LA) regimen for the maintenance of human immunodeficiency virus type 1 virologic suppression. Across the phase 3/3b trials, the most frequently reported adverse events were injection site reactions (ISRs).

Methods

We present pooled ISR characteristics and outcomes for participants receiving CAB + RPV LA through week 96 of the FLAIR and ATLAS-2M studies, and survey results from healthcare providers (HCPs) giving injections (eg, injectors) in the ATLAS, FLAIR, and ATLAS-2M studies to determine optimal injection techniques. Surveys were anonymous, self-administered online questionnaires that queried provider demographics, injection experience, and techniques to minimize pre-/postinjection discomfort. Data were summarized using descriptive statistics.

Results

Overall, 8453 ISRs were reported by 801 participants receiving ≥1 injection of CAB LA/RPV LA. Most ISRs were mild to moderate in severity (grade 1-2, 99%), with a median duration of 3 days (interquartile range, 2-4 days), and rarely led to withdrawal (2%). Surveys were completed by 181 HCPs across 113 sites. Pushing the intramuscular injection at slow speed (66%), bringing the medication to room temperature (58%), and relaxing the gluteus muscle before injecting (53%) were ranked as effective preinjection/injection procedure practices for minimizing pain. Most injectors (60%) indicated that a prone position provided optimal patient comfort, and 41% had no preference on injection medication order.

Conclusions

Taken together, the data demonstrate favorable tolerability with CAB + RPV LA injections over the long term and simple techniques routinely used by injectors to help optimize the administration of CAB + RPV LA injections.

The effects of vibration and pressure interventions on children's pain, fear and anxiety: A randomized controlled trial

AIM

The effects of vibration and pressure methods on the level of fear, anxiety, and pain of pediatric patients who were admitted to the emergency department for intramuscular injection were evaluated.

METHODS

This was a parallel group and a randomized controlled study conducted in Turkey. The study sample consisted of 114 children aged between 5 and 10 years who presented to the emergency department to receive intramuscular ceftriaxone injection as part of their treatment. The children were randomized into three groups: Vibration Intervention Group (n = 38), Pressure Intervention Group (n = 38) and Control Group (n = 38). Before the procedure, the level of anxiety and fear of the children were evaluated, and the level of perceived pain during the procedure was immediately evaluated after the intervention. Parents and nurses also rated the level of pain. Data were analyzed with non-parametric tests using SPSS version 26.0.

RESULTS

According to the evaluations made by children, mothers, and nurses, there was a significant difference between pain scores of children in the vibration and pressure intervention groups during the procedure and children in the control group (p < 0.000). There was a significant difference between anxiety and fear scores of children in the vibration and pressure groups and children in the control group before and after the intervention according to the evaluations of the children, mothers, and nurses (p < 0.000).

CONCLUSION

Vibration and pressure interventions used during intramuscular injections administered to children in the emergency department were found to reduce pain, anxiety, and fear based on the evaluations of children, mothers, and nurses.

PRACTICE IMPLICATIONS

Vibration and pressure are effective and useful in relieving pain associated with intramuscular injections in children aged between 5 and 10 years.

Effect of the Helfer skin tap technique on pain, anxiety, and fear in children undergoing intramuscular injection: An open-label randomized controlled study

BACKGROUND

Intramuscular injections, which children frequently experience during hospitalization, are one of the most significant causes of pain. Pain control is an important part of care. Therefore, it is necessary to provide practical methods in the field of nursing care to reduce injection-related pain.

AIM

This study aimed to determine the effect of the Helfer skin tap technique on pain, anxiety, and fear in children undergoing intramuscular injection.

METHOD

This randomized controlled clinical study (NCT05250804) was conducted in a pediatric emergency department between January and July 2022. A total of 64 children aged 4-10 years were randomly divided into two groups: 32 children in the Helfer skin tap group (HG), and 32 children in the control group (CG). Data were collected using the Wong-Baker FACES Pain Rating Scale, the Child Anxiety Scale-State, and the Child Fear Scale.

RESULTS

After the intramuscular injection, children in the HG had significantly lower levels of pain, anxiety, and fear than those in the CG, with mean scores of 3.25±1.50 versus 5.18±1.51, 5.87±1.56, versus 6.23±1.46, and 1.68±0.53 versus 3.15±0.76, respectively (p<0.001 for all scores).

CONCLUSION

The Helfer skin tap technique has positive effects on pain, anxiety, and fear in children during intramuscular injection. This technique can be used by nurses to reduce the pain, anxiety, and fear felt by children receiving an intramuscular injection.

Thermal imaging of local skin temperature as part of quality and safety assessment of injectable drugs

Injection of high-quality drugs can occasionally cause unexpected and unexplained local complications. As the current standard for drug quality control does not include an assessment of the local irritation effects of drugs, this effect may cause postinjection complications. Simultaneously, local irritation effects of the drugs can be assessed based on local tissue inflammation. The dynamics of local temperature can assess inflammation. Infrared monitoring of local skin temperature dynamics at subcutaneous, intramuscular, and intravenous injection sites of drugs under experimental and clinical conditions can improve their quality and safety. Therefore, there is a need to include dynamic thermography in the standard of biological evaluation of the quality and safety of drugs in the dosage form "solution for injections." This eliminates the local irritation and necrotizing activity of drugs and minimizes the development of local pain syndrome, aseptic inflammation, necrosis, and abscess.

Revolutionizing Fallopian Tube Evaluation in Infertility: Transvaginal Sonography Case Study

Background

Transvaginal four-dimensional hysterosalpingo-contrast sonography (TVS 4D-HyCoSy) is a pivotal diagnostic tool in the assessment and management of infertility. Conventionally, a 20mL syringe is employed for contrast agent injection, either at a constant or pulsatile pressure. However, in cases of bilateral fallopian tube obstruction, continued injection can lead to discomfort and excessive pressure within the uterine cavity, necessitating discontinuation of the examination.

Case Presentation

In this illuminating case study, a patient underwent TVS 4D-HyCoSy due to infertility concerns. Initial contrast agent injection failed to visualize both fallopian tubes, accompanied by acute pain. Bilateral tubal obstruction was diagnosed, prompting an innovative approach. A 2.5mL syringe was chosen for pulsed injection, leading to successful visualization of patency in one fallopian tube. Remarkably, the patient achieved natural pregnancy within three months of the examination.

Conclusion

Pulsed injection using a small-volume syringe emerges as a promising technique in cases of fallopian tube obstruction during TVS 4D-HyCoSy. This method not only enhances patient comfort but also improves the likelihood of visualizing fallopian tube patency, contributing to accurate infertility assessments. As a supplementary technique, it addresses limitations associated with constant pressure injection and offers a novel approach to enhance diagnostic success.

Effects of applications manual pressure and shotblocker to reduce needle-related pain and fear in children with type 1 diabetes mellitus

BACKGROUND

Pain and fear associated with insulin injections can cause children with type 1 diabetes mellitus to avoid insulin injections and skip doses.

OBJECTIVE

To evaluate and compare pain and fear levels in children aged 6-12 years receiving subcutaneous insulin injection using the manual pressure and ShotBlocker methods.

METHODS

A randomized controlled study was conducted with 90 children with type 1 diabetes who were allocated using block randomization to the manual pressure, ShotBlocker, and control groups (n = 30 in each group). Fear and pain levels were rated by the children, their parents, and a member of the study team immediately before and after insulin injection using the Children's Fear Scale and Wong-Baker Faces Pain Rating Scale, respectively.

RESULTS

All groups had similar self-, parent-, and researcher-reported levels of preprocedural pain and fear (p > 0.05). However, pain and fear scores were lower in the manual pressure and ShotBlocker groups than in the control group after injection (p = 0.0001). There was no significant difference in pain and fear scores between the two intervention groups (p > 0.05).

CONCLUSION

Manual pressure and the ShotBlocker both reduced fear and pain associated with insulin injection in 6- to 12-year-old children with type 1 diabetes.

IMPLICATIONS FOR PRACTICE

Both the manual pressure and ShotBlocker methods can easily be applied in children receiving insulin injections. As manual pressure is completely cost- and equipment-free, it is a useful option to reduce pain and fear related to insulin injection.

Clinical practice recommendations for nurse-administered intramuscular injections in mental health: A modified Delphi study

AIM

To develop clinical practice recommendations for nurse-administered intramuscular injections in mental health.

BACKGROUND

Intramuscular injection is the main route of long-acting injectable antipsychotics' administration that appear to improve the long-term prognosis of mental illness. Specific guidelines related to the nurse administration of intramuscular injections need to be updated and to explore not only the technical aspects of this procedure.

DESIGN

A modified RAND/University of California Los Angeles (UCLA) appropriateness method Delphi study was conducted between October 2019 and September 2020.

METHODS

A multidisciplinary steering committee conducted a literature review and developed a list of 96 recommendations. These recommendations were submitted in a two-round Delphi electronic survey to a panel of 49 experienced practicing nurses from five mental health hospitals in France. Each recommendation was rated for its appropriateness and applicability in clinical practice on a 9-point Likert scale. Consensus among nurses was evaluated. The steering committee discussed the results after each round and approved the final set of recommendations.

RESULTS

A final set of 79 specific recommendations were accepted for their appropriateness and applicability in clinical practice. Recommendations were classified in five domains: legal and quality assurance aspects, nurse-patient relationship, hygiene, pharmacology, and injection technique.

CONCLUSION

The established recommendations placed patients at the heart of the decisions concerning the intramuscular injection and underlined the need for specific training programs. Future research should focus on the integration of these recommendations in clinical practice, by both before-and-after studies and regular assessments of professional practices with relevant indicators.

IMPACT

The recommendations developed for good nursing practices explored not only the technical aspects but integrated the nurse-patient relationship. These recommendations may impact usual practices of administration of long-acting injectable antipsychotics and most of them could be applied in many countries.

Music medicine to improve the tolerability of onabotulinumtoxinA injections for chronic migraine: an open-label prospective cohort study

Introduction

OnabotulinumtoxinA for migraine involves 31 injected repeated every 12 weeks. Tolerability is a significant factor impacting discontinuation. Music medicine has not been studied previously as an intervention to improve the tolerability of injections.

Methodology

A single-centre prospective cohort study was undertaken. Following baseline, patients had music played during the procedure. Change in Visual Analogue Score (VAS) was assessed as the primary outcome.

Results

Over 6 months, 50 patients were recruited with a median age of 42, and median duration of therapy of 13.5 months. 'Quiet calm classical music' was associated with a significant reduction in VAS (z=-4.7, p<0.001). Duration of therapy, disease state or headache frequency had no correlation with change in VAS.

Conclusion

Music medicine is associated with a significant reduction in the procedural pain of onabotulinumtoxinA injections in prospective study. Further study is required to explore other modifiable factors to improve patient experience.

Adverse effects of dorsogluteal intramuscular injection versus ventrogluteal intramuscular injection: A systematic review and meta-analysis

AIMS

To determine adverse effects of ventrogluteal intramuscular injections versus dorsogluteal intramuscular injections.

DESIGN

A systematic review and meta-analysis.

METHODS

MEDLINE, EMBASE, CINHAL, CENTRAL, LILACS(BVS), BDENF (BVS), WoS, IRCTP(WHO), ClinicalsTrials.gov and PROSPERO databases were searched with no restriction on year or language. Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed.

RESULTS

A total of 1429 participants from 17 studies were included. The meta-analysis found that ventrogluteal injection site had significant relation to lower pain in 9 studies (SMD = -0.63, 95% CI = -0.87, -0.39), bleeding in 4 studies (SMD = -3.46, 95% CI = -6.07, -0.86) and hematoma in 2 studies; after 48 h (SMD = -0.25, 95% CI = -0.39, -0.11), and after 72 h (SMD = -0.16, 95% CI = -0.26, -0.06), if it was compared with dorsogluteal site injection. No differences were found when comparing the possibility of intramuscular injections given into de subcutaneous tissue. In three studies, ventrogluteal site did not significantly reduce the risk of subcutaneous injection (OR 0,62, 95% CI = 0.16, 2.41).

[Evidence-based practice and nursing: intramuscular injection in psychiatry]

Intramuscular injection is a frequent technical procedure in psychiatry. In France, nurses who perform this care do not have official guidelines for good practice. The advanced practice nurse is a field actor who can promote evidence-based practice to improve the quality of care for the benefit of the patient.

Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society-American Academy of Pain Medicine Pain Taxonomy Diagnostic Criteria for Acute Needle Pain

Needle procedures are among the most common causes of pain and distress for individuals seeking health care. While needle pain is especially problematic for children needle pain and associated fear also has significant impact on adults and can lead to avoidance of appropriate medical care. Currently there is not a standard definition of needle pain. A taxonomy, or classification system, for acute needle pain would aid research efforts and enhance clinical care. To meet this need, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks public-private partnership with the U.S. Food and Drug Administration, the American Pain Society, and the American Academy of Pain Medicine formed the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society-American Academy of Pain Medicine Pain Taxonomy initiative. One of the goals of this initiative was to develop taxonomies for acute pain disorders, including needle pain. To accomplish this, a working group of experts in needle pain was convened. Based on available literature and expert opinion, the working group used a 5-dimenional structure (diagnostic criteria, common features, modulating factors, impact and/or functional consequences, and putative mechanisms) to develop an acute pain taxonomy that is specific needle pain. As part of this, a set of 4 diagnostic criteria, with 2 modifiers to account for the influence of needle associated fear, are proposed to define the types of acute needle pain. PERSPECTIVE: This article presents a taxonomy for acute needle pain. This taxonomy could help to standardize definitions of acute pain in clinical studies of patients undergoing needle procedures.

Intramuscular vaccine administrations including the adoption of “Zeta-track technique” & “without aspiration slow injection technique” (ZTT & WASiT): a prospective review

Objective

To review the current literature on the practice of intramuscular injections (IMIs), focusing on immunizations.

Methods

The present study comprises 2 reviews, characterized by high-quality evidence, pertaining to the deployment of the slow injection technique without aspiration (referred to in this paper as the without-aspiration slow injection technique [WASiT]) and combined with the Zeta-track technique (ZTT). The literature review is oriented toward the analysis of 2 features associated with IMIs techniques: safety and pain, integrating new evidence on vaccinee positioning for each muscle site and general relaxation techniques in the multi-parametric analysis.

Results

The rigorous and in-depth reviews in the current study reveal the usefulness of including, among the international guidelines for via intramuscular immunizations, the adoption of WASiT only for compliant vaccinees, and in combination with all validated techniques for IMIs, and the use of ZTT limitedly if specific well-developed muscles are indicated. All the technique’s limitations are exposed.

Conclusions

Future research directions are presented by including the author’s study designs to provide indirect evidence for the validity of the rationale of the slow injection technique using scientific methods, and for the conduction of future randomized controlled trials (RCTs) focused on revisiting the adoption of ZTT in a dynamic and integrated immunizations protocol in anterolateral thigh (ALT), ventrogluteal (VG), and also in the deltoid muscle, in the specific cases analyzed.

Clinical implementation of long-acting antiretroviral treatment in high-income countries: challenges and advantages

PURPOSE OF REVIEW

Long-acting antiretroviral therapy (LA-ART) brings a paradigm shift to HIV care with injectable cabotegravir/rilpivirine (IM-CAB/RPV) in current or imminent use in several countries. This brings the usual opportunities and challenges of a new therapy, plus requirements to adapt services to reliably deliver injections and ensure patients understand advantages and limitations. We summarise key considerations for implementation in high-income countries.

RECENT FINDINGS

Monthly IM-CAB/RPV is noninferior to oral ART and monthly IM-CAB/RPV to 1-monthly in carefully selected virally suppressed people. The numerically higher virological failure rate on two-monthly IM-CAB/RPV warrants close attention and careful monitoring. Implementation projects report positive experiences for patients and staff, but also barriers. Data is needed in younger people, pregnancy/breastfeeding, and in those with detectable viraemia secondary to suboptimal adherence.

SUMMARY

We highlight a paucity of real-world data and key unanswered questions. Existing data on injection techniques may have implications for training; monitoring of outcomes is crucial to ensure clinical trial results are replicated in real-life. Better understanding of treatment failure, and individualised therapy, is crucial, and it is important to repeat patient preference surveys as new data emerges to ensure decisions are based on the most recent evidence of benefit vs risk.
