Measuring progress in maternal and newborn health care in Mexico: validating indicators of health system contact and quality of care.

BACKGROUND: The majority of births in Mexico take place in a health facility and are attended by a skilled birth attendant, yet maternal mortality has not declined to anticipated levels. Coverage estimates of skilled attendance and other maternal and newborn interventions often rely on women's self-report through a population-based survey, the accuracy of which is not well established. METHODS: We used a facility-based design to validate women's report of skilled birth attendance, as well as other key elements of maternal, newborn intrapartum, and immediate postnatal care. Women's reports of labor and delivery care were collected by exit interview prior to hospital discharge and were compared against direct observation by a trained third party in a Mexican public hospital (n = 597). For each indicator, validity was assessed at the individual level using the area under the receiver operating curve (AUC) and at the population level using the inflation factor (IF). RESULTS: Five of 47 indicators met both validation criteria (AUC > 0.60 and 0.75 < IF < 1.25): urine sample screen, injection or IV medication received during labor, before the birth of the baby (i.e., uterotonic for either induction or augmentation of labor), episiotomy, excessive bleeding, and receipt of blood products. An additional 9 indicators met criteria for the AUC and 18 met criteria for the IF. A skilled attendant indicator had high sensitivity (90.1 %: 95 % CI: 87.1-92.5 %), low specificity (14.0 %: 95 % CI: 5.8-26.7 %) and was suitable for population-level estimation only. CONCLUSION: Women are able to give valid reports on some aspects of the content of care, although questions regarding the indication for interventions are less likely to be known. Questions that include technical terms or refer to specific time periods tended to have lower response levels. A key aspect of efforts to improve maternal and newborn health requires valid measurement of women's access to maternal and newborn health interventions and the quality of such services. Additional work on improving measurement of population coverage indicators is warranted.

Barriers to the use of maternity waiting homes in indigenous regions of Guatemala: a study of users' and community members' perceptions.

Maternal mortality among indigenous women in Guatemala is high. To reduce deaths during transport from far-away rural communities to the hospital, maternity waiting homes (MWH) were established near to hospitals where women with high-risk pregnancies await their delivery before being transferred for labour to the hospital. However, the homes are under-utilised. We conducted a qualitative study with 48 stakeholders (MWH users, family members, community leaders, MWH staff, Mayan midwives and health centre and hospital medical staff) in Huehuetenango and Cuilco to identify barriers before, during and after the women's stay in the homes. The women most in need - indigenous women from remote areas - seemed to have least access to the MWHs. Service users' lack of knowledge about the existence of the homes, limited provision of culturally appropriate care and a lack of sustainable funding were the most important problems identified. While the strategy of MWHs has the potential to contribute to the prevention of maternal (as well as newborn) deaths in rural Guatemala, they can only function effectively if they are planned and implemented with community involvement and support, through a participatory approach.

Acceptance of a new technology for management of obstetric hemorrhage: a qualitative study from rural Mexico.

We conducted a qualitative study to explore responses to a low-technology first-aid device for management of life-threatening obstetric hemorrhage in rural health facilities in Mexico. This entailed in-depth, semistructured interviews with clinical and administrative staff (n = 70) involved in pilot studies of the nonpneumatic antishock garment (NASG) at primary health care facilities and rural hospitals. We found that staffs' response fell into four categories: owning, doubting, resisting, and rejecting. Overall, there were positive reactions to the garment as a relevant technology for saving women's lives. Findings will be used for future implementation of the garment and other new technologies.

Exploring the costs and economic consequences of unsafe abortion in Mexico City before legalisation.

An assessment of abortion outcomes and costs to the health care system in Mexico City was conducted in 2005 at a mix of public and private facilities prior to the legalisation of abortion. Data were obtained from hospital staff, administrative records and patients. Direct cost estimates included personnel, drugs, disposable supplies, and medical equipment for inducing abortion or treating incomplete abortions and other complications. Indirect patient costs for travel, childcare and lost wages were also estimated. The average cost per abortion with dilatation and curettage was 143 US dollars. For manual vacuum aspiration it was 111 US dollars in three public hospitals and 53 US dollars at a private clinic. The average cost of medical abortion with misoprostol alone was 79 US dollars. The average cost of treating severe abortion complications at the public hospitals ranged from 601 US dollars to over 2,100 US dollars. Increasing access to manual vacuum aspiration and early abortion with misoprostol could reduce government costs by 62%, with potential savings of up to 1.6 million US dollars per year. Reducing complications by improving access to safe services in outpatient settings would further reduce the costs of abortion care, with significant benefits both to Mexico's health care system and women seeking abortion. Additional research is needed to explore whether cost savings have been realised post-legalisation.

Accuracy of a semi-quantitative urine pregnancy test compared to serum beta-hCG measurement: a possible screening tool for ongoing pregnancy after medication abortion.

PURPOSE: Medication abortion protocols commonly rely on ultrasound or serum hCG measurement to confirm completion. In order to explore the use of a urine-based test to screen for ongoing pregnancy, we compared the diagnostic accuracy of a recently developed semi-quantitative urine pregnancy test to serum beta-hCG testing. METHODS: We evaluated the urine test with 97 women in early pregnancy at a hospital and private clinic in Mexico City. The results of the urine test (hCG level > or <1000 IU/L) were correlated with those of a serum quantitative beta-hCG immunoradiometric assay. RESULTS: The sensitivity of the urine test to identify individuals with a serum beta-hCG level >1000 IU/L was 88.6% (95% CI 74.6- 95.7%), and its specificity was 71.7% (95% CI 57.4-82.8%). CONCLUSION: The reasonably high sensitivity of this urine test suggests it might be useful as a screening test to detect ongoing pregnancy after medication abortion. Future research should evaluate its utility in clinical follow-up protocols.

Prevalencia de gérmenes causantes de faringoamigdalitis en niños. Sensibilidad y respuesta terapéutica a la ampicilina- / Prevalence of germs causing pharyngotonsillitis in children. Sensiativity and therapeutic response to ampicillin

Este estudio fue realizado para analizar la prevalencia de gérmenes aislados en pacientes pediátricos con faringoamigdalitis bacteriana en la consulta privada a nivel de la comunidad, y al mismo tiempo evaluar la respuesta clínica al tratamiento con ampicilina. Material y métodos. Se incluyó a 516 pacientes de 12 ciudades de México, con diagnóstico de faringoamigdalitis bacteriana. Se practicaron exudados faríngeos antes y después del tratamiento con ampicilina y se probó la susceptibilidad in vitro a varios antibióticos (incluida la ampicilina). Resultados. El patógeno más aislado fue el estreptococo betahemolítico del grupo A de Lancefield (S. pyogenes), con 26.6 por ciento de prevalencia. En dichos cultivos la sensibilidad in vitro a ampicilina fue de 100 por ciento para el estreptococo grupo A betahemolítico. La respuesta global a ampicilina fue satisfactoria en 95 por ciento de los pacientes. Conclusiones. Los resultados de este estudio confirman datos anteriormente reportados en población pediátrica a nivel de la comunidad en México y otros países en vías de desarrollo; contrastan con los obtenidos en países del primer mundo y confirman la utilidad del tratamiento de las faringoamigdalitis bacterianas con ampicilina en países en vías de desarrollo.
