A survey demonstrating that the procedural experience of residents in internal medicine, critical care and emergency medicine is poor: training in ultrasound is required to rectify this

BACKGROUND

Training in procedural skills is often suboptimal. The aim of this study was to quantify the needs of residents in internal medicine (IM), critical care (CC), and emergency medicine (EM) for instruction in ultrasound-guided procedures.

METHODS

All IM, EM and CC residents (n = 200) at King Abdulaziz Medical City, Riyadh, Saudi Arabia, were invited to participate in a questionnaire-based survey to identify skill and experience gaps. The contribution of procedural skills to patient care (i.e. applicability) and proficiency in the sterile technique required to perform ultrasound-guided procedures were rated on Likert scales. Data on training, accreditation, and experience with and without ultrasound were collected.

RESULTS

The overall response rate was 72% (IM 91%, CC 100%, EM 40%). Although the sample reported that procedural skills were very applicable, 19% (IM n = 25, EM n = 2) had not performed any procedures. However, five residents were accredited in point-of-care ultrasound, 61% of the sample had performed ultrasound-guided procedures and 65% had used landmark techniques. Whilst more internists had performed procedures using landmark techniques, CC and EM residents had performed more ultrasound-guided procedures. Whilst CC residents had not missed any opportunities to perform procedures because supervisors were less available, EM (6) and IM (89) residents had. Whilst skill gaps were only identified in the IM residency programme, experience gaps were present in all three residency programmes. The IM residency programme had larger experience gaps than the CC and EM programmes for all procedural skills.

DISCUSSION

Residents in IM, CC and EM perceive that ultrasound-guided procedures are relevant to their practice. However, the IM residents performed fewer procedures than CC residents and EM residents at least partly because internists also lack skills in ultrasound. Training in ultrasound-guided procedures may reduce the use of landmark techniques and improve patient safety. Residents in IM, CC and EM therefore require training in ultrasound-guided procedures.

Focused Cardiac Ultrasound is Applicable to Internal Medicine and Critical Care but Skill Gaps Currently Limit Use

Context

Coronavirus Disease 2019 (COVID-19) put a spotlight on focused cardiac ultrasound (FoCUS). However, the spectra of cardiac disease, and the resources available for investigation vary internationally. The applicability of FoCUS to internal medicine (IM) and critical care medicine (CCM) practice in Saudi Arabia and their current use of FoCUS are unknown.

Aims

To determine the applicability of FoCUS to IM and CCM practice in Saudi Arabia and quantify the residents’ current proficiency, accreditation and use of FoCUS.

Methods

A questionnaire was distributed to the residents in IM and CCM at our institution to determine their proficiency, use of FoCUS, and perceptions of its applicability.

Results

In total, 110 residents (IM 100/108; CCM 10/10) participated (Response rate 93.2%) and reported that FoCUS was very applicable to their practice, most specifically for pericardial effusion, right heart strain, and left ventricular function. Two IM residents had received postgraduate training, ten used FoCUS regularly, none were accredited and overall self-reported proficiency was poor. In contrast all CCM residents had received postgraduate training and reported regular use of FoCUS. Two were accredited.

Conclusions

Whilst FoCUS is applicable to IM practice in Saudi Arabia, significant skills gaps exist. The skills gap in CCM is lower but unaccredited practice is common. Our residents’ responses were similar to those from Canada. Thus, international standardization of FoCUS training could be considered.

Association of Chorioamnionitis With Bronchopulmonary Dysplasia Among Preterm Infants: A Systematic Review, Meta-analysis, and Metaregression

IMPORTANCE

Bronchopulmonary dysplasia (BPD), a chronic lung disease of prematurity, remains one of the major and most common complications of very preterm birth. Insight into factors associated with the pathogenesis of BPD is key to improving its prevention and treatment.

OBJECTIVE

To perform a systematic review, meta-analysis, and metaregression of clinical studies exploring the association between chorioamnionitis (CA) and BPD in preterm infants.

DATA SOURCES

PubMed and Embase were searched without language restriction (last search, October 1, 2018). Key search terms included bronchopulmonary dysplasia, chorioamnionitis, and risk factors.

STUDY SELECTION

Included studies were peer-reviewed studies examining preterm (<37 weeks' gestation) or very low-birth-weight (<1500 g) infants and reporting primary data that could be used to measure the association between exposure to CA and the development of BPD.

DATA EXTRACTION AND SYNTHESIS

The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guideline was followed. Data were independently extracted by 2 researchers. A random-effects model was used to calculate odds ratios (ORs) and 95% CIs. Heterogeneity in effect size across studies was studied using multivariate, random-effects metaregression analysis.

MAIN OUTCOMES AND MEASURES

The primary outcome was BPD, defined as supplemental oxygen requirement on postnatal day 28 (BPD28) or at the postmenstrual age of 36 weeks (BPD36). Covariates considered as potential confounders included differences between CA-exposed and CA-unexposed infants in gestational age, rates of respiratory distress syndrome (RDS), exposure to antenatal corticosteroids, and rates of early- and late-onset sepsis.

RESULTS

A total of 3170 potentially relevant studies were found, of which 158 met the inclusion criteria (244 096 preterm infants, 20 971 CA cases, and 24 335 BPD cases). Meta-analysis showed that CA exposure was significantly associated with BPD28 (65 studies; OR, 2.32; 95% CI, 1.88-2.86; P < .001; heterogeneity: I2 = 84%; P < .001) and BPD36 (108 studies; OR, 1.29; 95% CI, 1.17-1.42; P < .001; heterogeneity: I2 = 63%; P < .001). The association between CA and BPD remained significant for both clinical and histologic CA. In addition, significant differences were found between CA-exposed and CA-unexposed infants in gestational age, birth weight, odds of being small for gestational age, exposure to antenatal corticosteroids, and early- and late-onset sepsis. Chorioamnionitis was not significantly associated with RDS (48 studies; OR, 1.10; 95% CI, 0.92-1.34; P = .24; heterogeneity: I2 = 90%; P < .001), but multivariate metaregression analysis with backward elimination revealed that a model combining the difference in gestational age and the odds of RDS was associated with 64% of the variance in the association between CA and BPD36 across studies.

CONCLUSIONS AND RELEVANCE

The results of this study confirm that among preterm infants, exposure to CA is associated with a higher risk of developing BPD, but this association may be modulated by gestational age and risk of RDS.

Chorioamnionitis as a risk factor for retinopathy of prematurity: An updated systematic review and meta-analysis

The role of chorioamnionitis (CA) in the development of retinopathy of prematurity (ROP) is difficult to establish, because CA-exposed and CA-unexposed infants frequently present different baseline characteristics. We performed an updated systematic review and meta-analysis of studies reporting on the association between CA and ROP. We searched PubMed and EMBASE for relevant articles. Studies were included if they examined preterm or very low birth weight (VLBW, <1500g) infants and reported primary data that could be used to measure the association between exposure to CA and the presence of ROP. Of 748 potentially relevant studies, 50 studies met the inclusion criteria (38,986 infants, 9,258 CA cases). Meta-analysis showed a significant positive association between CA and any stage ROP (odds ratio [OR] 1.39, 95% confidence interval [CI] 1.11 to 1.74). CA was also associated with severe (stage ≥3) ROP (OR 1.63, 95% CI 1.41 to 1.89). Exposure to funisitis was associated with a higher risk of ROP than exposure to CA in the absence of funisitis. Additional meta-analyses showed that infants exposed to CA had lower gestational age (GA) and lower birth weight (BW). Meta-regression showed that lower GA and BW in the CA-exposed group was significantly associated with a higher risk of ROP. Meta-analyses of studies with data adjusted for confounders could not find a significant association between CA and ROP. In conclusion, our study confirms that CA is a risk factor for developing ROP. However, part of the effects of CA on the pathogenesis of ROP may be mediated by the role of CA as an etiological factor for very preterm birth.
