Details

a) Financial interventions

Health worker payment methods

Lo 2008 [22]

Increase physician fees for vaginal birth after caesarean (VBAC) fee to the same level as caesarean section

Increase in vaginal birth physician fees to that of caesarean section

National Health Insurance Taiwan equalised the fee for VBAC to that of a caesarean in April 2003. In May 2005, the fee for vaginal birth was raised to the equivalent of that of a caesarean section.

Keeler 1996 [23]

Equalising physician fees for vaginal and caesarean delivery

Revision to fee schedule for obstetric and other procedures including equalising the fees for vaginal and caesarean sections.

Liu 2007 [24]

National Health Insurance (NHI)

National Health Insurance (NHI) which equalized price for CS and vaginal delivery implemented in 1995.

Health organization payment methods

Diagnosis-related group payment system

Kim 2016 [25]

Diagnosis-related Group (DRG) payment system

Diagnosis-related Group (DRG) payment system with fixed reimbursement for physicians regardless of cost of CS procedure. To promote vaginal delivery, the medical fee for vaginal birth increased by 50%, raising per diem profits above those of CS delivery and additional reimbursements were given for vaginal delivery of a patient over 35.

Lee 2007 [26]

Diagnosis-Related Group (DRG) payment system.

Diagnosis-Related Group (DRG) prospective payment system (PPS) which sets a fixed fee for service. In a DRG group, the fee difference between CS and vaginal delivery is less than in a fee-for-service (control) system (in the DRG system the fee for CS was less than 2 times that for vaginal delivery. In the fee-for-service, the fee for CS was 2.7 times that for vaginal delivery).

Three set DRG codes: CS, vaginal delivery with complication, vaginal delivery without complication. The fee for a set code is determined by the severity of complication/comorbidity index.

Global budget payment (GBP) system

Chen 2014 [27]

Global fee for obstetric services, increasing reimbursement for vaginal delivery to be equal to CS

Co-payment when CS not indicated

Policy I: Financial incentives to encourage vaginal delivery through a global fee for obstetric services and increasing reimbursement for vaginal delivery to be equal to that of caesarean sections.

Policy II: Copayment when caesarean section is not medically indicated (aimed to reduce the demand for elective caesarean procedure).

Kozhimannil 2018 [28]

Global fee for uncomplicated deliveries (regardless of mode)

Single blended payment rate for uncomplicated births (regardless of mode of delivery).

Before the policy, facility fees were $3144 and $5266 for uncomplicated vaginal and caesarean births, respectively. As of October 1, 2009, the policy changed the rate to $3528 for uncomplicated births, regardless of mode of delivery.

Liu 2013 [29]

Global Budget System

Hospital-based Self-Management (HBSM)

Global Budget System (GBS) in July 2002. This entails direct government funding for hospitals and by extension cost-reduction and elimination of unnecessary services.

Hospital-based Self-Management (HBSM) in August 2005 involves post-operative peer reviews and audits to reduce medical service costs incurred by CS.

Case-based payment system

Tsai 2006 [30]

Vaginal birth after caesarean section (VBAC) case payment program

Vaginal birth after caesarean section (VBAC) case payment program introduced by Taiwan’s Bureau of National Health Insurance (BNHI).

Cap-based payment system

Misra 2008 [31]

Cap based payment system

The HealthChoice managed care program (mandatory for Medicaid recipients, and have risk-adjusted capitation rates designed to individualize care and reduce unnecessary CS rates.

Chen 2016 [32]

Cap-based maternity insurance scheme (MIS)

Cap-based maternity insurance scheme (MIS)

• Limits unnecessary expensive procedures by not reimbursing hospitals above price of cap. Patients no longer pay upfront.

The cap system does not reimburse hospitals for costs above the threshold (per capita) which disincentivizes doctors from prescribing unnecessary procedures.

Other financial interventions

Karami 2018 [33]

Financial incentive and free vaginal delivery policy

Financial incentive and free vaginal delivery policy

• Health Sector Evolution Plan (HSEP) reform provided free-of-charge inpatient services for vaginal delivery and offered financial incentives for providers to promote vaginal rather than CS delivery.

b) Regulatory and legislative interventions

Studnicki 1997 [34]

Legislatively imposed practice guidelines

Legislatively imposed practice guidelines

• Mandated that practice guidelines regarding caesarean section deliveries be disseminated to obstetric physicians.

• The law also required that peer review boards at hospitals be established to review caesarean deliveries and that the exact dates of implementation of the guidelines be reported to a state agency.

The provider hospitals were required to provide copies of the guidelines to obstetric physicians and other persons appropriately credentialed to perform caesarean deliveries, establish a peer review board to review caesarean deliveries and ensure that its findings are shared, incorporate the peer review board reviews and reports into the hospital’s quality assurance monitoring and peer review process, and to report to the state Agency for Health Care Administration (AHCA) the dates of the implementation of the practice parameters and the initial meeting of the peer review board.

Yu 2017 [35]

Multifaceted institutional and policy interventions.

Institutional interventions

Health education (face-to-face weekly educational meetings between patients and hospital staff, training for obstetricians and midwives) painless delivery introduction, and doula care.

Policy interventions

1. Development plans

• The Regulation for the Management of Maternal Health Care and the Norms of Maternal Health Care

• The Development Plan for Women in Wenzhou

Enhance health education about maternal health;

Popularize knowledge about perinatal health care;

2. Evaluation criteria

Medical Quality Management and Control Indicators for Tertiary Comprehensive Hospitals.

The CS rate was included among patient safety indicators.

c) Other interventions

Snowden 2016 [36]

Oregon “hard-stop” policy limiting elective inductions and caesarean deliveries before 39 weeks of gestation

Oregon “hard-stop” policy limiting elective inductions and caesarean deliveries before 39 weeks of gestation. Introduced by the Oregon Perinatal Collaborative in 2011.

The hard-stop policy limited early-term deliveries by requiring review and approval for any delivery without documented indication before 39 weeks of gestation (in contrast with other approaches, e.g., “soft-stop” policies, which give providers more discretion).
