C-section most common inpatient surgery

June 3, 2014—Women’s health–related issues led to the highest number of hospital stays in 2012–2013, according to new data from the Canadian Institute for Health Information (CIHI). Giving birth was the leading reason for inpatient hospitalization, accounting for 369,454 hospital stays. There were more Caesarean sections (C-sections) in Canada than any other inpatient surgery.

Hysterectomies were also among the top 5 reasons for inpatient surgeries. According to CIHI’s report Inpatient Hospitalizations, Surgeries and Childbirth Indicators in 2012–2013, there were more than 2.9 million inpatient hospitalizations across Canada that year. The report highlights the most common reasons for inpatient hospitalizations and inpatient surgeries across the country.

Canadians admitted to hospital stayed an average of 7.1 days, which is similar to recent years. Of the top 5 reasons for hospitalization, heart failure had the longest average hospital stay (9.3 days). Of the top 5 reasons for surgery, hip replacement had the longest average hospital stay (7.7 days).


Top 5 reasons for inpatient surgeries in 2012–2013:

  • C-section delivery: 100,686 surgeries
  • Knee replacement: 57,829 surgeries
  • Hip replacement: 47,297 surgeries
  • Hysterectomy: 40,127 surgeries
  • Coronary artery dilation: 40,074 surgeries

Top 5 reasons for inpatient hospitalizations in 2012–2013:

  • Giving birth: 369,454 hospitalizations
  • Respiratory disease: 76,705 hospitalizations
  • Heart attack: 68,835 hospitalizations
  • Pneumonia: 60,077 hospitalizations
  • Heart failure: 56,260 hospitalizations


“We continue to see a moderate decline in the rate of hospitalizations across Canada each year, as well as in how long patients stay in hospital,” says Greg Webster, Director, Acute and Ambulatory Care Information Services. “This is in part due to the increased availability of outpatient procedures and services, as well as some services shifting to out-of-hospital facilities (for example, birthing centres). When examining hospitalization trends, it is important to look at specific conditions and procedures, as not all are declining and some are actually increasing (for example, hip and knee replacements).”
