St. Jude Maternity Hospital St. Jude Maternity Hospital (JMH) a nonprofit organization had a mission to deliver healthy babies with normal weights, and to offer medical care to expectant mothers regardless of their ability to pay. Since its inception, the JMH had enjoyed a reputation for achieving its mission. In fact, in 2005, the Regional Health Authority (RHA) rated the JMH among the top 25 best performing maternity hospitals in three categories: proper recording of data relating to expectant mothers, appropriate involvement of obstetricians and midwives in prenatal care and providing mothers with basic advice on infant feeding. However, in 2010, its reputation deteriorated so much so that the RHA rated the JMH among the bottom 25 per cent for its maternity services. Dr. Rita Smith, Chief Medical Officer (CMO) of the JMH, was under pressure to improve the rating of the hospital, as the future funding depended on living up to the expectations of the stakeholders such as doctors, nurses, other allied health professionals (AHP) and administrators. As a result, Smith, needed to conduct a survey of expectant mothers to understand the issues and their implications for stakeholders. Delivering healthy babies with normal weight was crucial to achieving JMHs mission. ST. JUDE MATERNITYHOSPITAL To achieve their mission, the JMH doctors, nurses and AHPs worked hard with expectant mothers to live up to their expectations for high quality maternity services. They particularly paid attention to expectant mothers with little or no formal education, in which case, doctors and nurses had an extra responsibility to educate and create awareness about prenatal care such as proper nutritional care, regular health check-up, blood work and immunization. Success of JMHs mission depended on delivery of healthy babies with normal weights. Dr. Julia Albert had been CMO of the hospital since 1995, during which time she took great care in achieving the mission of the hospital and in raising funds for operation of the hospital through grants and donations. Under her leadership until December 2005, the RHA rated JMH among the top 25 best performing maternity hospitals.JMH received an average score of 4.6 on a 5-point scale on 25 performance indicators. In fact, JMH received five out of five in three categories: proper recording of data relating to expectant mothers, the appropriate involvement of obstetricians and midwives in antenatal care, and providing mothers with basic advice on infant feeding. Proud of this accomplishment, Dr. Albert announced her retirement in December 2005,

and left for good to spend the rest of her life in her homeland. In January 2006, the JMH Board of Trustees appointed a locally trained CMO Dr. Rita Smith. However, in December 2010, Smith was shocked to learn the RHA rated the JMH among the bottom 25 per cent for its maternity services. According to the RHA report, about 10 per cent of expectant mothers, who were surveyed immediately after giving birth to a baby stated that, although JMH provided prenatal education to about 40 per cent of expectant mothers who needed it, the great majority did not adhere to the basic advice, such as impact of smoking during pregnancy on the babys health, the effect of mothers age on babys weight, the importance and benefits of breast feeding, and the importance of maternal and child nutrition throughout pregnancy. It was also revealed that only about 50 per cent of women at JMH were able to fully understand the prenatal sessions compared to the national average of 60 per cent. JMH was also penalized for failing to provide statistics regarding breastfeeding, mothers educational qualification, birth order of baby and smoking behavior during pregnancy, among other factors. Only 38 per cent of women said they were happy with the quality of support they received prior to hospitalization, during hospitalization and after discharge. Following release of the RHA report, Peter Rao, chairman of the JMH Board of Trustees, said, Dr. Smith, we are disappointed to read the recent report about the JMH. Thisis not what we stand for. We would like a full review of the maternity services. We have significantly invested in JMH in 2011 and committed extra funding for the future. We are dedicated to continually improving the maternity services. Please submit your recommendations to the board by the end of December 2012 as to how to improve the rating conducted by the RHA. Smith was under pressure to improve the rating of the hospital. She was also aware JMH received $300,000 in 2011 for the refurbishment of JMH from a local philanthropist, Dr. David Greenburg. Dr. Greenburg said, The support is to help strengthen the hospital as a referral healthcare facility to enrich the lives of expectant mothers and babies. Smith knew obtaining future funding would be difficult with this low rating. She knew she needed to conduct a survey of expectant mothers to understand all the issues and their implications for doctors, nurses, AHPs and administrators. After returning to her chamber, Smith called her deputy, Dr. Ruby Kite, and said, We need to investigate the issues and questions that have arisen in the recent JMH Board of Trustees meeting. We need to know what the numbers are telling us. We need to be as specific as we can to make actionable recommendations to the board. Please send me your recommendations by the end of November 2012. To answer the questions and to develop insights, Dr. Kite surveyed the birth recovery ward at the hospital and collected responses from 33 mothers. Their responses appear in Exhibit 1.
