The Association Between Hospital Volume and Survival After Acute Myocardial Infarction in Elderly Patients

Why do high-volume hospitals achieve better outcomes? A systematic review about intermediate factors in volume–outcome relationships

“…'Hospital level factors' and 'compliance to evidence based processes of care' were included in ten and seven studies respectively ( Table 2). One study fitted into two categories because both 'level of specialization' and 'hospital level factors' were included in this review [20]. Nearly half of the studies focused on cancer surgery (44%), followed by cardiovascular care (30%) pediatric/neonatal care (19%), and orthopedic surgery (7%).…”

“…-Physician certification [40] -Neonatal intensive care level [26] -Surgeon specialty training (gynecologic, oncologists/ gynecologists, general surgeons, and other specialty) [25] -Surgeon specialty (general versus urologist) [22] -Level of specialization (general, semi-specialized or specialized) [24] -Treatment by board certified colorectal surgeons and surgeon's age [41] -Children's hospital status [42] -Surgeon specialty [23] -Physician specialty (cardiologist, internist, generalist) [28] -Surgeon designation (designated general surgeon, specialist surgeon) [27] -Specialty of attending physician [20] Hospital level factors (10 studies)…”

Impact of hospital volume on clinical outcomes of endoscopic biliary drainage for acute cholangitis based on the Japanese administrative database associated with the diagnosis procedure combination system

“…Especially over the past decade, many studies have shown a significant association between the volume of hospital services and patient outcomes for a wide variety of surgical procedures and certain medical conditions [9][10][11]. Although the reasons for the relationship between hospital volume and patient outcome have not been explained clearly, these results suggest that hospital volume is a significant independent indicator of clinical outcomes [7][8][9][10][11].…”

Does patient volume affect clinical outcomes in adult intensive care units?

“…Recent evidence favours higher volume hospitals for complex planned surgical procedures [1][2][3][4][5][6]. Such a volume-outcome relationship exists for some medical conditions such as myocardial infarction and diabetes mellitus [7][8][9]. As a result of the difficulty in evaluating actual outcome measures in a reliable and timely fashion volume has become more attractive as a surrogate marker of quality [10].…”
