Self-perception of competences in clinical practice among recently graduated physicians from Lima, Peru

Objective To describe the self-perception of basic competencies in clinical practice and evaluate their associated factors, among recently graduated physicians from Lima, Peru. Methods Cross-sectional study. We evaluated the self-perception of the competencies in recently graduated physicians of four dimensions of the Tuning Project. Each item had six possible responses on a Likert scale: “non-existent” (1 point), “insufficient” (2 points), “sufficient” (3 points), “good” (4 points), “very good” (5 points) and “excellent” (6 points). To evaluate associated factors of the average scores for each dimension, we used linear regressions with the bootstrap method. Results We analyzed data from 425 (54.9% were between 22 and 25 years old), which represent 31.1% of all physicians who graduated in 2016 from all medical schools located in Lima. The average self-perception score of the assessed dimensions was, in descending order: 4.49 for carrying out a patient consultation with a patient; 4.13 for carrying out practical procedures; 4.12 for providing immediate care of medical emergencies; and 4.04. for applying the principles, skills, and knowledge of evidence-based medicine (EBM). Regarding the factors associated with the average score per dimension, physicians from one university had higher average scores in all dimensions, and having done an externship and done an internship at social security hospitals was associated with a higer score with self-perception in two dimensions. Conclusion Self-perception of competence was greater for the patient consultation dimension, and lower for the EBM. Only physicians from one university had higher average scores in all dimensions.


Introduction
Medical training should ensure the acquisition of the basic competencies a physician will need to achieve proper job performance [1,2]. Although there is no consensus on what such competencies should be, some initiatives have been proposed, such as the "Tuning Project" [3,4]. The Tuning Project which aims to establish the minimum general competencies a physician must have was launched by the European Commission [2,5,6], and has also been contextualized for Latin America with the participation of different universities in the region, including some universities in Peru [4,7].
Previous studies conducted in Portugal [8], UK [9,10,11], Zambia [12], China [13], Chile [14,15], and Mexico [16] have evaluated the competencies acquired by medical students during their undergraduate training, reporting heterogeneous methodology and results. However, we have not found studies conducted in Peru, a country with particular needs concerning medical education.
In Peru, most of the recently graduated physician enrol for the Rural Health Service (SERUMS, by its acronym in Spanish), a social service that lasts a year, in which, most of the times, this physician is the only health care professional working at the rural communities [17]. Therefore, the recently graduated physician must have the minimum medical competencies and confidence (translated into an adequate self-perception of the knowledge) to practice them. However, only two previous studies [18,19] have assessed the competencies in this population. These studies were conducted in small samples, did not use a standardized list of competencies such as the Tuning Project (which prevents comparison with international publications), and did not assess the factors associated with having these competencies (which is necessary tailor interventions).
Given the need of information regarding this subject, we conducted the present study to describe the self-perception of competencies in clinical practice using Tuning Project dimensions and evaluated their associated factors among recently graduated physicians from Lima, Peru.

Study design and population
We carried out a cross-sectional study in physicians that had graduated less than one year ago from any of the medical schools located in Lima (Peru). Participants were recruited in the "VI SERUMS National Convention", which was held in April 2017 and organized by the Peruvian Medical College. This event aimed to provide information and advice regarding the SERUMS to physicians who were starting the service in the following weeks. All medical schools in the city of Lima were invited to participate in this convention through their corresponding representatives.
The SERUMS is a rural social service that takes place in the first level of care and is a requirement for physicians to be able to work for the Peruvian government and to get into medical residency in Peru. Thus, most Peruvian physicians start SERUMS right after finishing their undergraduate studies [17].
The study population consisted of all recently graduated physicians who attended the event and who agreed to participate in the study. Those who had incomplete data for the variables of interest and those who did not pursue undergraduate studies in a Peruvian university were excluded from the analysis.

Procedures
Each physician was approached by trained pollsters when registering for the "VI SERUMS National Convention". Pollster gave them a brief explanation about the study, invited them to participate, and handled them an informed consent form. Those who agreed to participate and signed the informed consent received a self-administered questionnaire and were explained that they could take as much time as needed to respond in the conference room. Two researchers tabulated all the questionnaires independently in an ad hoc database. Then, a third researcher compared the databases and inconsistencies were resolved by revising the questionnaires again.

Questionnaire
The questionnaire used for this study had four sections: 1) sociodemographic and academic data of the participant, 2) self-perceived competencies for general medicine, 3) self-perceived competencies for obstetric care, and 4) self-perceived competencies for mental health diagnosis and treatment. For this article, the first two sections were evaluated. The questionnaire was reviewed by experts and recently graduated physicians that did not attend the "VI SERUMS National Convention" who gave suggestions to make the questions clearer.
The section of self-perceived competencies for general medicine was constructed based on the adapted Tuning Project's dimensions for Latin America [20]. The "Tuning Project", founded in 2000 by the European Commission, made a consensus (with the participation of graduates, employers, academics and students) with the purpose of establishing a list of basic competences for different careers (including medicine) and, therefore, standardize higher education programs in Europe [2,5,6]. Subsequently, the Tuning Project was contextualized in Latin America, with the participation of 19 universities in fifteen countries [4,7].
The Tuning Project has eleven general dimensions: 1) carry out an ambulatory consultation with a patient; 2) provide immediate care of medical emergencies; 3) carry out practical procedures; 4) apply the principles, skills, and knowledge of evidence-based medicine (EBM); 5) assess clinical presentations, order investigations, make differential diagnoses, and negotiate a management plan; 6) communicate effectively in a medical context; 7) apply ethical and legal principles in medical practice; 8) prescribe drugs; 9) assess the psychological and social aspects of a patient's illness; 10) use information and information technology effectively in a medical context; 11) apply scientific principles, method, and knowledge to medical practice and research; and 12) work effectively in a health care system and engage with population health issues.
In the "self-perceived competences for general medicine" section, we included all the items of the first four dimensions (consultation, emergencies, procedures, and EBM), since we considered those to be the most important ones for recently graduated physicians.

Main variable: self-perception of basic medical skills
We assessed all 28 items of the selected dimensions: carry out an ambulatory consultation with a patient (6 items), provide immediate care of medical emergencies (6 items), carry out practical procedures (13 items), and apply the principles, skills, and knowledge of evidence-based medicine (3 items).
To assess each item, we used a Likert scale, as previous studies on the matter [8]. Each item was evaluated with the question "Do you consider that your level of competence in the following item is ...?", scoring each of the possible answers on a Likert scale: "non-existent" (1 point), "insufficient" (2 points), "sufficient" (3 points), "good" (4 points), "very good" (5 points), and "excellent" (6 points).

Other variables
In addition, the following variables were studied: age, sex, the university where the participant completed his/her undergraduate studies

Data analysis
For the descriptive analysis, we used absolute and relative frequencies (for the categorical variables), as well as measures of central tendency and dispersion (for the quantitative variables).
Linear regression models with bootstrap methods were used to calculate the coefficients (β) and their respective 95% confidence intervals (95% CI) for the associations between three covariates (the university in which the participant completed his/her undergraduate studies, having done extracurricular externships, and the hospital in which the participant did his/her internship) and the mean selfperception scores obtained from the four dimensions studied. All analyses were performed using the Stata v.14.0 software.

Ethical aspects
This study was approved by the Institutional Committee of Ethics in Research of the Hospital Nacional Docente Madre-Niño -HONADOMANI (RCEI-40). Participation was voluntary, and data confidentiality was maintained.

Results
A total of 693 physicians attended the "VI SERUMS National Convention" in 2017, from which 520 physicians accepted to participate in the study, of whom 95 were excluded (three for not having completed their undergraduate studies in Peru, 31 for having completed their undergraduate studies more than a year ago, and 61 for not answering any of the questions about self-perceived competencies). Finally, we analyzed data from 425 recently graduated physicians of the all of the universities in Lima (8 universities), which represent 31.1% (425/1368) of all physicians who graduated in 2016 from medical schools located in Lima [21].
Concerning self-perception of physicians about their competencies, the average score for the dimensions evaluated was, in descending order: 4.49 for carrying out a patient consultation with a patient; 4.13 for carrying out practical procedures; 4.12 for providing immediate care of medical emergencies; and 4.04 for applying the principles, skills, and knowledge of evidence-based medicine.
The percentage of physicians who perceived that their competence was adequate (good, very good or excellent) was greater for the following items: measure blood pressure (96.2%), take a history (93.4%), suture wounds (92.7%), and carry out the physical examination (92.2%); and lower for the items: perform blood transfusions (33.6%), perform basic respiratory function tests (42.4%), provide advanced life support (48.5%), administer intravenous therapy and use infusion devices (51.8%), and perform and interpret electrocardiograms (53.4%) ( Table 2).
Regarding the factors associated with the average score obtained in each dimension, it was found that UPCH physicians had higher average scores in all dimensions, UPC physicians in two dimensions ("carry out practical procedures" and "apply the principles, skills, and knowledge of evidence-based medicine"), and UPSJB physicians only in the dimension of "carry out practical procedures". On the other hand, only USMP physicians had a lower average score in "carrying out practical procedures" and "applying the principles, skills, and knowledge of evidencebased medicine." Additionally, we found that those who had done extracurricular externships for at least two months at any time during undergraduate studies obtained a higher average score in the dimensions of carrying out an ambulatory consultation with a patient and practical procedures and that those who had done internships at EsSalud hospitals had a higher average score than those who did them at MINSA hospitals, for "carrying out practical procedures" and "apply the principles, skills, and knowledge of evidence-based medicine" (Table 3).

Descriptive results
A survey performed in 2014 in Portugal in 1591 recently graduated physicians from seven medical schools aimed to evaluate the selfperception of the competencies proposed by the Tuning Project [8]. This study is very similar to ours. The self-perception average score in our study was higher for the "carrying out a consultation with a patient" dimension and lower for the "applying the principles, skills, and knowledge of evidence-based medicine" dimension. Conversely, the Portugal study found that, for the dimensions addressed by our study, the physicians reported a higher score for "applying the principles, skills, and knowledge of evidence-based medicine", followed by "carrying out a consultation with a patient" [8]. This suggests that our population may have a disadvantage regarding evidence-based medicine competencies.
Competencies in evidence-based medicine are closely related to specific courses and training, in addition to the examples given by professors in the clinical setting [22,23]. Thus, a possible explanation of the low self-perception of these competencies in our population is the lack of participation in evidence-based medicine courses, research centers, scientific societies of students, or rotations in hospitals where evidence-based medicine is deeply rooted in the clinical practice.
Within the "providing immediate care of medical emergencies" dimension, we found that items with a lower proportion of physicians self-perceived as competent included "providing advanced life support" and "providing trauma care according to current national guidelines". This is in line with the results in the Portugal study [8]. Also, one study conducted in Zambia among physicians who had completed their internships found low perceived skills to provide advanced life support [24]. A possible explanation is that when severely traumatized patients or patients needing advanced life support go to hospitals, residents or specialists may be the ones who take care of these patients, giving little opportunity to students. In Peru, physicians can acquire or strengthen these competencies through specialized courses after undergraduate studies. However, the lack of these competencies among recently graduated physicians is worrisome, since most of these physicians are going lead care in rural services as soon as they finish their undergraduate studies [17].
In our study, the general procedures with the highest proportion of physicians who self-perceived as competent included: measuring blood pressure (96.2%), suturing wounds (92.7%), and administering subcutaneous and intramuscular injections (84.5%). Conversely, one study conducted in Zambia found that 37.5% and 14.3% felt very competent for administering intramuscular injections and suturing wounds, respectively [24], while in Portugal, the mean competence score (which ranged from 0 to 5) was 2.61 and 2.64 for self-perceived competence for suturing wounds and measuring blood pressure, respectively [8]. The general procedures with the lowest proportion of physicians who felt competent in our study included: performing blood transfusions (33.6%), performing basic respiratory function tests (42.4%), and administering intravenous therapy, and use infusion devices (51.8%). Similar to the findings in Portugal [8], the mean competence scores (which ranged from 0 to 5) for performing blood transfusions (0.82), administering intravenous therapy (1.47), and performing respiratory function tests (1.77) were the lowest. This may be because these activities are usually carried out by nurses, and medical schools do not emphasize its learning.

Associated factors
The higher self-perception in all dimensions of UPCH graduates in comparison with other universities could be related to the fact that this university has active clinical simulation centers [25], where theoretical knowledge is strengthened by practising in real situations [26]. It may also be associated with specific courses or with greater participation in research since this university is among those with the highest scientific output in Peru [27]. On the other hand, UPC graduates have a higher self-perception than other universities in the dimensions of "carry out practical procedures" and "apply the principles, skills, and knowledge of EBM". UPC also have a curricular externship, case-based evaluations, and active clinical simulation centers [28,29], but its first class of graduate physicians was in 2013 [30], so it is expectable that their medical curriculum is still under improvement.
Regarding the difference found between EsSalud and MINSA hospitals, it is possible that in some hospitals the academic aspect of the possibilities of performing procedures with patients is greater. However, it should be noted that eligibility to do an internship at EsSalud is achieved through a national examination among those who wish to apply, thus, students who are admitted to the internship program at EsSalud may have already on average more self-perceived skills than those of MINSA. However, in our study, we found a higher self-perception score in those physicians who carried out their internship in an EsSalud's hospital only in two dimensions ("carry out practical procedures" and "apply the principles, skills, and knowledge of EBM"). Despite this previous preparation of students who apply to the EsSalud internship have, it is necessary to also consider some characteristics of the hospital that could impact the development of medical competencies such as the administrative burden for the student [31] or the logistic (number of cases, number of interns, and residents) of the hospital, which reduces the number of cases in which students are involved and decreases individualized learning. Subsequent studies should explore these variables and their implications for the development of medical competencies.
We found an association between having done extracurricular externships and having a higher score in the competencies of carrying out an ambulatory consultation with a patient and practical procedures, which suggests that externships could be a useful intervention to improve procedural skills. However, it is also possible that students with greater motivation (and, therefore, better skills) are those who actively seek to do an externship. Thus, the direction of this association cannot be established, and it should be better studied.

Implications and recommendations
The shortcomings found in this study must be taken into consideration by Peruvian universities, which should ensure that all their Table 3.

In bold: statistically significant associations. * Each university was compared with the others (for example, the coefficient for USMP had as reference the rest of the physicians who did not study at USMP).

physicians graduate with optimal competencies in general medicine [2]. Universities should consider a methodology to education according to the approach of competencies based on results, this being the current scene in medical training, that performed a holistic view of education based on a definition of the competencies as a combination of knowledge, skills, and attitudes [32]. Although, in Peru, level the theoretical knowledge acquired by physicians during undergraduate studies is evaluated through the national examination of medicine (ENAM, by its acronym in Spanish) and its results are taken into account for licensing medical schools [27], it is also interesting to evaluate the practical competencies or structured clinical examination using minimum competencies checklists (like "Objective Structured Clinical Examination" type tests), or at least students' self-perception of these, to have a wider perspective of the Peruvian medical education [24,33].
The fact that the scores of self-perception of competencies differed across medical schools suggests that there may be differences in the medical education process. Thus, it is important to assess the differences in education contents and methodologies, and make efforts to ensure that medical students acquire a set of basic competencies needed for their labor as physicians and especially for the SERUMS.

Limitations
Some limitations of this study should be considered: 1) Although the ideal way to evaluate medical competencies is by observing these practices in real scenarios, we have opted to evaluate the selfperception of competencies as a proxy. Thus, some physicians may tend to over-estimate or under-estimate their real competences. However, there is a correlation between self-perceived and actual competences [24,34], and self-perceived competence regarding certain items also evaluates the physician's motivation to perform such items (since those who do not feel competent will tend to avoid doing it) [35,36]. Also, some studies have shown that self-perception is related to real knowledge [37]. Moreover, self-perceived competencies are important as self-perception of young physicians reflect the subject's motivation and can influence their attitudes towards performing a test, and so influence care decisions [38,39]. 2) We analyzed data of the third part of physicians who graduated during 2016 from medical schools located in Lima, specifically those who attended the "VI SERUMS National Convention". Physicians who did not attend to such convention may have some different characteristics, such as a lower rate of planning to perform the SERUMS, so the extrapolation should be performed carefully [40] 3) Our response rate was around 75%, which may bias the results in such a way that those who felt not competent in the evaluated dimensions may have chosen not to participate in the study. This would overestimate the perception of competencies found in our study. 4) Participants were physicians who planned to underwent the SERUMS, so we are probably loosing information from those who have decided to follow medical residency abroad, who may have higher self-perception of certain competencies. 5) Being an exploratory analysis, the influence of several potential confounders was not collected, so future studies are needed to confirm our results.

Conclusion
We evaluated the self-perception of competencies of 442 physicians. The average self-perception score was higher for the "carrying out a consultation with a patient" dimension and lower for the "applying the principles, skills, and knowledge of evidence-based medicine" dimension. The factors associated with this score were: having completed their undergraduate studies in certain universities, having done an externship for at least two months during undergraduate studies, and having done an internship at EsSalud (instead of MINSA) hospitals.
