“…Of the 45 studies that focused on the types and/or measurement of hospital managers’ competencies, 60% (27/45) used quantitative methods (mostly surveys and questionnaires, followed by statistical analyses), 17.8% (8/45) used qualitative methods (interviews with thematic analysis), and 22.2% (10/45) used a mixed-methods approach. Majority of studies reported that both ‘hard competencies’ such as specific technical knowledge ( 44 , 48 ) or skills acquired through practical training ( 41 , 44 , 63 , 72 ), and ‘soft competencies,’ e.g., adaptability ( 63 ), leadership ( 30 , 43 , 48 , 67 , 69 ), effective communication ( 9 , 30 , 44 , 45 , 48 , 67 , 69 ), teamwork ( 9 , 30 , 44 ), time management ( 43–45 , 72 ), creativity ( 43 , 44 , 48 ), and decision-making ( 43 , 67 ), are needed for effective hospital management. As a consequence, many researchers pointed out the importance of both ‘external’ formal education training/certificates as well as ‘internal’ peer-support, mentoring, and/or coaching as complementary competency improvement approaches.…”
