Expanding midwifery care in the United States: Implications for clinical outcomes and cost.

BACKGROUND: This study compared clinical and financial outcomes for low-risk birthing people between those attended by midwives and those attended by obstetricians during hospital births. METHODS: We conducted a retrospective cohort analysis of births from January 1, 2016 to December 31, 2020 at hospitals participating in a perinatal quality improvement collaborative, Obstetrical Care Outcomes Assessment Program (OB COAP), in the Northwest region of the United States and estimated risk ratios using a multivariate regression approach with a modified Poisson binomial for mode of delivery, labor interventions, and newborn outcomes comparing midwife-led to obstetrician-led care. Using publicly available data on average costs of vaginal and cesarean births, we then extrapolated the cost differences in care between midwives and obstetricians. RESULTS: Births in the midwife group were less likely to be associated with induction (17.6% vs. 20.3% RR 0.74; 95% CI 0.70-0.78), epidural use (58.9% vs. 76.3% RR 0.78; 95% CI 0.77-0.80), and episiotomy (2.2% vs. 3.4% RR 0.68; 95% CI 0.58-0.81). Cesarean birth was also lower in the midwifery group (7.8% vs. 12.3% RR 0.68, 95% CI 0.62-0.73), without a corresponding increase in risk in adverse neonatal outcomes. We estimated that expanding midwifery care to 100% of low-risk births across the United States could save as much as $340 million per year. CONCLUSIONS: Midwifery care is associated with a lower risk of cesarean birth and other interventions versus care provided by obstetricians and is therefore likely lower-cost.

Fishing with bed nets on Lake Tanganyika: a randomized survey.

BACKGROUND: Malaria is among the most common causes of death along Lake Tanganyika, a problem which many aid organizations have attempted to combat through the distribution of free mosquito bed nets to high-risk communities. The Lake Tanganyika Floating Health Clinic (LTFHC), a health-based non-governmental organization (NGO), has observed residents of the Lake Tanganyika basin using bed nets to fish small fry near the shoreline, despite a series of laws that prohibit bed net use and other fine-gauge nets for fishing, implemented to protect the near-shore fish ecology. The LTFHC sought to quantify the sources of bed nets and whether they were being used for fishing. METHODS: The LTFHC conducted a survey of seven lakeside villages in Lagosa Ward, Tanzania. The government has divided each village into two to six pre-existing geographic sub-villages depending on population size. Seven households per sub-village were chosen at random for survey administration. The survey consisted of 23 questions regarding mosquito bed net practices, including the use of bed nets for fishing, as well as questions pertaining to any perceived changes to the fish supply. RESULTS: A total of 196 surveys were administered over a four-week period with a 100% response rate. Over 87% of households surveyed have used a mosquito bed net for fishing at some point. The majority of respondents reported receiving their bed net for free (96.4%), observing "many" residents of their village using bed nets for fishing (97.4%), and noticing a subjective decrease in the fish supply over time (64.9%). CONCLUSIONS: The findings of this study raise concerns that the use of free malaria bed nets for fishing is widespread along Lake Tanganyika, and that this dynamic will have an adverse effect on fish ecology. Further studies are indicated to fully define the scope of bed net misuse and the effects of alternative vector control strategies in water-based communities.

Pelvic exenteration in the age of modern chemoradiation.

BACKGROUND: To examine outcomes after pelvic exenteration in women treated with modern chemoradiation and surgical techniques. METHODS: All patients at our institution with a diagnosis of gynecologic malignancy who underwent pelvic exenteration after treatment with chemoradiation between 1/90 and 6/08 were evaluated with a retrospective chart review. RESULTS: 44 women were identified, of whom 29 (66%) had cervical, 6 (14%) had uterine, 5 (11%) had vaginal, and 4 (9%) had vulvar cancer. The majority of patients (82%) were initially treated with external beam whole-pelvic radiation with concurrent cisplatin. 38 patients (86%) underwent exenteration for a central pelvic recurrence, and the remaining 6 patients (14%) for radiation necrosis. The most common surgical complication was transfusion requirement in 36 patients (82%), followed by wound infection in 15 (34%), small bowel obstruction in 8 (18%), and sepsis in 6 (14%). The median time spent in the ICU post-operatively was 2 days. One patient (2%) died during her post-operative hospital stay. The mean EBL overall was 2497 cc and the mean operative time was 544 min. Use of electrothermal bipolar coagulation, which was used in 64% of the exenterations, significantly reduced blood loss (3679 cc vs. 1836 cc, p=0.014). After exenteration, 21 patients (48%) were diagnosed with a recurrence of cancer, and the mean progression free survival was 31 months. Patients who received exenteration less than 2 years after their initial chemoradiation had a significantly shorter overall survival time (8 months vs. 33 months, p=0.016). CONCLUSIONS: Approximately 50% of women develop recurrence following exenterations done after chemoradiation. Survival is significantly longer in patients who necessitate exenteration greater than 2 years out from initial treatment. Electrothermal bipolar coagulation appears to significantly reduce blood loss during these surgeries.

Ovarian cancer in the elderly: outcomes with neoadjuvant chemotherapy or primary cytoreduction.

BACKGROUND: Recent studies have suggested inferior outcomes for elderly women with ovarian cancer. Our goal was to evaluate neoadjuvant chemotherapy versus primary cytoreduction in elderly women. METHODS: A retrospective chart review was performed for women aged 65+ diagnosed with ovarian cancer at our institution between 1997 and 2007. Univariate and multivariate logistic regression models were used to evaluate complication rates. Survival was evaluated with Cox regression and the Kaplan-Meier method. RESULTS: One hundred seventy-five patients were identified, 34 (19%) of whom were aged 80+. Those aged 65-79 and those 80+ received neoadjuvant chemotherapy with equal frequency (19% vs. 21%, p=0.92). Treatment with neoadjuvant chemotherapy was associated with odds ratios of 0.80 (95% CI 0.37-1.75) for surgical complications and 0.79 (95% CI 0.33-1.90) for chemotherapeutic complications. In those aged 80+, the frequency of surgical complications (OR 1.01, p=0.62) and chemotherapeutic complications (OR 1.04, p=0.78) did not differ compared to younger patients. Overall survival did not differ based on initial treatment regimen, with 34 months in the primary surgery group and 29 months in the neoadjuvant chemotherapy group (p=0.65). The median disease specific survival for those aged 65-79 was 35 months, and 24 months in those aged 80+ (p=0.15). Post-operative mortality for patients aged 80+ was zero. CONCLUSIONS: In our patient population, those aged 80+ have similar surgical and chemotherapy-related complication rates and comparable survival to those aged 65-79. The choice of initial treatment modality does not appear to impact survival when the decision is made in a selective fashion.
