Impact of nurse staffing on reducing infant, neonatal and perinatal mortality rates: Evidence from panel data analysis in 35 OECD countries.

Objectives: To investigate the magnitude of effect nurse staffing had on decreasing the newborn mortality rates in member countries of Organisation for Economic Co-operation and Development (OECD).

Methods: The statistical technique of panel data analysis was applied to explore the possibility of association between the number of nurses' density per 1,000 population and infant, neonatal and perinatal mortality rates (IMR, NMR and PMR) per 1000 births. The observations of 35 OECD countries were collected over the period of 2000 through 2016.

Role of nurses in improving patient safety: Evidence from surgical complications in 21 countries.

Objectives: To analyze the role of nurse staffing in improving patient safety due to reducing surgical complications in member countries of Organization for Economic Co-operation and Development (OECD).

Methods: The number of practicing nurses' density per 1000 population and five surgical complications indicators including foreign body left in during procedure (FBL), postoperative pulmonary embolism (PPE) and deep vein thrombosis (DVT) after hip and knee replacement, postoperative sepsis after abdominal surgery (PSA) and postoperative wound dehiscence (PWD) were collected in crude rates per 100,000 hospital discharges for age group of 15 years old and over within 30 days after surgery based on surgical admission-related and all admission-related methods. The observations of 21 OECD countries were collected from OECD Health Statistics during 2010-2015 period.
