Does Cost Influence the Choice of Disposable Versus Reusable Instruments? Mailed Survey of Obstetrician/Gynaecologists.

OBJECTIVE: A "cost-awareness" campaign was undertaken at a tertiary hospital from 2015 to 2016 to raise awareness about costs of disposable versus reusable instruments in laparoscopic procedures. We undertook a before and after survey of obstetrician/gynecologists (Ob/Gyns) to find out if the campaign had affected their attitudes about choosing disposable versus less expensive reusable instruments. METHODS: In 2015 (before the cost-awareness campaign) and 2017 (after the cost-awareness campaign), all full-time university-associated Ob/Gyns were mailed a cover letter, questionnaire, and coffee card ($5) with a postage-paid return envelope. Responses (with unique identification) from Ob/Gyns who perform laparoscopic procedures were entered into a password-protected REDCap database on a secure server. All statistical analyses were performed using SAS software version 9.4 (SAS Institute Inc, Cary, NC) (Canadian Task Force Classification II-3). RESULTS: A total of 35 of 42 eligible Ob/Gyns (85%) with a median 10 years in practice completed questionnaires before and after the intervention. The majority had undertaken minimally invasive surgery training, mainly during residency (80%) and conferences (71%). Before the intervention, the three most important qualities influencing their decision to use a particular instrument were safety (66%), effectiveness (57%), and personal experience (49%). After the intervention, the three most important qualities were effectiveness (57%), safety (57%), and ease of use (46%). Device cost was ranked sixth (26%) before and seventh (17%) after the intervention. The majority (57%) of participants did not change their choice of disposable or reusable instruments, or they would make the choice according to the specific procedure. CONCLUSION: Given the current economy, operative costs are constantly under review. Knowledge about Ob/Gyns' attitudes provides information to design more effective awareness campaigns to encourage use of less costly instruments. To change practice, a campaign increasing Ob/Gyns' exposure to less expensive but safe and effective instruments may help to increase uptake and potentially lead to cost reduction. Cost awareness alone is unlikely to change practice.

Glyceryl trinitrate to reduce the need for manual removal of retained placenta following vaginal delivery: the GOT-IT RCT.

BACKGROUND: Retained placenta is associated with postpartum haemorrhage and can lead to significant maternal morbidity if untreated. The only effective treatment is the surgical procedure of manual removal of placenta, which is costly, requires skilled staff, requires an operative environment and is unpleasant for women. Small studies suggest that glyceryl trinitrate may be an effective medical alternative. OBJECTIVE: To determine the clinical effectiveness and cost-effectiveness of sublingual glyceryl trinitrate spray compared with placebo in reducing the need for manual removal of placenta in women with retained placenta after vaginal delivery following the failure of current management. DESIGN: A group-sequential randomised double-blind placebo-controlled trial with a cost-effectiveness analysis. SETTING: There were 29 obstetric units in the UK involved in the study. PARTICIPANTS: There were 1107 women (glyceryl trinitrate group, n = 543; placebo group, n = 564) randomised between October 2014 and July 2017. INTERVENTIONS: Glyceryl trinitrate spray was administered to 541 women in the intervention group, and a placebo was administered to 563 women in the control group. MAIN OUTCOME MEASURES: Four primary outcomes were defined: (1) clinical - the need for manual removal of placenta, (2) safety - measured blood loss, (3) patient sided - satisfaction with treatment and side effects and (4) economic - cost-effectiveness of both treatments using the UK NHS perspective. Secondary clinical outcomes included a > 15% decrease in haemoglobin level, time from randomisation to delivery of placenta in theatre, the need for earlier manual removal of placenta than planned, increase in heart rate or decrease in blood pressure, requirement for blood transfusion, requirement for general anaesthesia, maternal pyrexia, and sustained uterine relaxation requiring additional uterotonics. RESULTS: No difference was observed between the glyceryl trinitrate group and the control group for the placenta remaining undelivered within 15 minutes of study treatment (93.3% vs. 92%; odds ratio 1.01, 95% confidence interval 0.98 to 1.04; p = 0.393). There was no difference in blood loss of > 1000 ml between the glyceryl trinitrate group and the control group (22.2% vs. 15.5%; odds ratio 1.14, 95% confidence interval 0.88 to 1.48; p = 0.314). Palpitations were more common in the glyceryl trinitrate group than in the control group after taking the study drug (9.8% vs. 4.0%; odds ratio 2.60, 95% confidence interval 1.40 to 4.84; p = 0.003). There was no difference in any other measures of patient satisfaction between the groups. There was no difference in costs to the health service between groups (mean difference £55.30, 95% confidence interval -£199.20 to £309.79). Secondary outcomes revealed that a fall in systolic or diastolic blood pressure, or an increase in heart rate, was more common in the glyceryl trinitrate group than in the control group (odds ratio 4.9, 95% confidence interval 3.7 to 6.4; p < 0.001). The need for a blood transfusion was also more common in the glyceryl trinitrate group than in the control group (odds ratio 1.53, 95% confidence interval 1.04 to 2.25; p = 0.033). CONCLUSIONS: Glyceryl trinitrate spray did not increase the delivery of retained placenta within 15 minutes of administration when compared with the placebo, and was not cost-effective for medical management of retained placenta. More participants reported palpitations and required a blood transfusion in the glyceryl trinitrate group. Further research into alternative methods of medical management of retained placenta is required. TRIAL REGISTRATION: Current Controlled Trials ISRCTN88609453.

A retained placenta is diagnosed when, following the birth of a baby, the placenta is not delivered. When this situation occurs, women are at risk of bleeding heavily. The only way to treat a retained placenta is for a trained doctor to remove it by an operation in theatre. This procedure can be painful and upsetting. Furthermore, the timing of the operation can interrupt mother­baby bonding immediately after giving birth. The study tested if the use of glyceryl trinitrate spray, given as two puffs under the woman's tongue following the diagnosis of retained placenta, may help the placenta to deliver without an operation. The study also tested if glyceryl trinitrate was safe, assessed what women thought about the treatment and compared the costs of glyceryl trinitrate with those of current operative management. This study included 1107 women diagnosed with retained placenta following the birth of their baby. Half of the women were treated with glyceryl trinitrate spray and the other half were treated with a dummy spray, which looked identical but did not contain the active treatment. If the placenta delivered within 15 minutes of the study treatment being taken, this was considered a success. However, if the placenta did not deliver within 15 minutes and the woman had to have her placenta removed by an operation, then this was viewed as unsuccessful. Neither the woman nor the clinical staff knew if the treatment given was the glyceryl trinitrate spray or the dummy spray. The results indicate that, although women were happy to be involved in the trial and the treatment was safe, the use of glyceryl trinitrate spray did not reduce the need for the placenta to be manually removed by an operation in theatre. Furthermore, glyceryl trinitrate spray was not cost-effective.

A pragmatic group sequential, placebo-controlled, randomised trial to determine the effectiveness of glyceryl trinitrate for retained placenta (GOT-IT): a study protocol.

INTRODUCTION: A retained placenta is diagnosed when the placenta is not delivered following delivery of the baby. It is a major cause of postpartum haemorrhage and treated by the operative procedure of manual removal of placenta (MROP). METHODS AND ANALYSIS: The aim of this pragmatic, randomised, placebo-controlled, double-blind UK-wide trial, with an internal pilot and nested qualitative research to adjust strategies to refine delivery of the main trial, is to determine whether sublingual glyceryl trinitrate (GTN) is (or is not) clinically and cost-effective for (medical) management of retained placenta. The primary clinical outcome is need for MROP, defined as the placenta remaining undelivered 15 min poststudy treatment and/or being required within 15 min of treatment due to safety concerns. The primary safety outcome is measured blood loss between administration of treatment and transfer to the postnatal ward or other clinical area. The primary patient-sided outcome is satisfaction with treatment and a side effect profile. The primary economic outcome is net incremental costs (or cost savings) to the National Health Service of using GTN versus standard practice. Secondary outcomes are being measured over a range of clinical and economic domains. The primary outcomes will be analysed using linear models appropriate to the distribution of each outcome. Health service costs will be compared with multiple trial outcomes in a cost-consequence analysis of GTN versus standard practice. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the North-East Newcastle & North Tyneside 2 Research Ethics Committee (13/NE/0339). Dissemination plans for the trial include the Health Technology Assessment Monograph, presentation at international scientific meetings and publication in high-impact, peer-reviewed journals.

Pay-for-performance reduces healthcare spending and improves quality of care: Analysis of target and non-target obstetrics and gynecology surgeries.

OBJECTIVE: In Korea, the Value Incentive Program (VIP) was first applied to selected clinical conditions in 2007 to evaluate the performance of medical institutes. We examined whether the condition-specific performance of the VIP resulted in measurable improvement in quality of care and in reduced medical costs. DESIGN: Population-based retrospective observational study. SETTING: We used two data set including the results of quality assessment and hospitalization data from National Health Claim data from 2011 to 2014. PARTICIPANTS: Participants who were admitted to the hospital for obstetrics and gynecology were included. A total of 535 289 hospitalizations were included in our analysis. METHODS: We used a generalized estimating equation (GEE) model to identify associations between the quality assessment and length of stay (LOS). A GEE model based on a gamma distribution was used to evaluate medical cost. The Poisson regression analysis was used to evaluate readmission. MAIN OUTCOME MEASURES: The outcome variables included LOS, medical costs and readmission within 30 days. RESULTS: Higher condition-specific performance by VIP participants was associated with shorter LOSs, decreases in medical cost, and lower within 30-day readmission rates for target and non-target surgeries. LOS and readmission within 30 days were different by change in quality assessment at each medical institute. CONCLUSIONS: Our findings contribute to the body of evidence used by policy-makers for expansion and development of the VIP. The study revealed the positive effects of quality assessment on quality of care. To reduce the between-institute quality gap, alternative strategies are needed for medical institutes that had low performance.

Pre-pregnancy and Early Prenatal Care are Associated with Lower Risk of Ectopic Pregnancy Complications in the Medicaid Population: 2004-08.

BACKGROUND: Ectopic pregnancy causes significant maternal morbidity and mortality. Complications are more common among women with Medicaid or no insurance compared to those with private insurance. It is unknown whether preventive care prior to pregnancy and prenatal care, which are covered by Medicaid, would decrease complications if they were more fully utilised. METHODS: Medicaid claims were used to identify a clinical cohort of women who experienced an ectopic pregnancy during 2004-08 among all female Medicaid enrolees from a large 14-state population, ages 15-44. Diagnosis and procedure codes were used to identify ectopic pregnancies and associated complications. The primary outcomes were complications associated with ectopic pregnancy: blood transfusion, sterilisation, or hospitalisation with length of stay greater than 2 days. Independent variables were documentation of preventive care within 1 year prior to the ectopic pregnancy and prenatal care within 4 months prior. RESULTS: Controlling for race, age, and state of residence, women's risks of any ectopic pregnancy complication were independently higher among those who did not receive any Medicaid-covered preventive care within 1 year before the ectopic pregnancy compared to those who did (RR 1.12, 95% confidence interval (CI) 1.09, 1.16), and among those who did not receive any Medicaid-covered prenatal care within 4 months prior, compared to those who did (RR 1.89, 95% CI 1.83, 1.96). CONCLUSIONS: Pre-pregnancy and prenatal care are independently associated with decreased risk of ectopic pregnancy complications among Medicaid beneficiaries.

Population-based study on the effect of socioeconomic factors and race on management and outcomes of 35,535 inpatient ectopic pregnancies.

STUDY OBJECTIVE: To evaluate whether socioeconomic variables influence the management and outcomes of ectopic pregnancies. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Hospitals in the United States participating in the Health Care Cost and Utilization Project. PATIENTS: Women (n = 35 535) with a primary discharge diagnosis of ectopic pregnancy. INTERVENTIONS: Effect of socioeconomic factors and race/ethnicity on management and adverse outcomes of ectopic pregnancy. MEASUREMENTS AND MAIN RESULTS: During the 9-year study, 35 535 ectopic pregnancies were identified. The development of hemoperitoneum in 8706 patients (24.50%) was the most common complication. Asian race was the sociodemographic variable most predictive of hemoperitoneum (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.24-1.61; p < .01) and transfusion (OR, 1.62; 95% CI, 1.39-1.89; p < .01), and Medicare status was most influential on prolonged hospitalization (OR, 1.83; 95% CI, 1.36-2.47; p < .01). Major complications were not affected by socioeconomic factors. Laparotomy in 25 075 patients (70.6%) was the most common treatment option. Patients of Asian or Pacific Islander descent were least likely to be treated non-surgically (OR, 0.62; 95% CI, 0.51-0.76; p < .01), whereas Medicare recipients were most likely to be treated non-surgically (OR, 1.70; 95% CI, 1.32-2.18; p < .01). All non-white groups were less likely to undergo a laparoscopic approach. CONCLUSION: Major complications from ectopic pregnancy are not influenced by socioeconomic variables; however, less serious complications and management approaches are persistently affected.

Evaluating the cost-effectiveness of prenatal surgery for myelomeningocele: a decision analysis.

OBJECTIVE: To determine whether prenatal myelomeningocele repair is a cost-effective strategy compared to postnatal repair. METHODS: Decision-analysis modeling was used to calculate the cumulative costs, effects and incremental cost-effectiveness ratio of prenatal myelomeningocele repair compared with postnatal repair in singleton gestations with a normal karyotype that were identified with myelomeningocele between T1 and S1. The model accounted for costs and quality-adjusted life years (QALYs) in three populations: (1) myelomeningocele patients; (2) mothers carrying myelomeningocele patients; and (3) possible future siblings of these patients. Sensitivity analysis was performed using one-way, two-way and Monte Carlo simulations. RESULTS: Prenatal myelomeningocele repair saves $ 2 066 778 per 100 cases repaired. Additionally, prenatal surgery results in 98 QALYs gained per 100 repairs with 42 fewer neonates requiring shunts and 21 fewer neonates requiring long-term medical care per 100 repairs. However, these benefits are coupled to 26 additional cases of uterine rupture or dehiscence and one additional case of neurologic deficits in future offspring per 100 repairs. Results were robust in sensitivity analysis. CONCLUSION: Prenatal myelomeningocele repair is cost effective and frequently cost saving compared with postnatal myelomeningocele repair despite the increased likelihood of maternal and future pregnancy complications associated with prenatal surgery.

The comparison of an inexpensive-modified transobturator vaginal tape versus TVT-O procedure for the surgical treatment of female stress urinary incontinence.

OBJECTIVE: To compare the safety and efficacy of an inexpensive-modified transobturator vaginal tape procedure with the transobturator tension-free vaginal tape (TVT-O) procedure for the surgical treatment of female stress urinary incontinence (SUI). MATERIALS AND METHODS: Patients with SUI were randomly allocated to either the test group receiving the inexpensive-modified transobturator vaginal tape procedure or the control group receiving the GYNECARE TVT-O procedure. Treatment outcomes and Quality-of-life scores were recorded and analyzed between two groups. RESULTS: A total of 156 patients were enrolled in this trial. Eighty patients underwent the modified transobturator vaginal tape procedure. Among them 75(93.8%) were cured and 5(6.2%) were improved. The rest of the 76 patients underwent the GYNECARE TVT-O procedure with a 92% (70 of 76) cure rate and an 8% (6 of 76) improvement rate. No inefficient or aggravated cases occurred in both groups. The success rates between groups had no significant statistic difference (p > 0.05). The operative time, blood loss, hospital stay, and medical cost were significantly lower in the test group (p < 0.01); the increases in Quality-of-life scores were comparable between groups. CONCLUSIONS: The modified transobturator vaginal tape procedure is an efficacious and economic surgical treatment for female SUI.

Obstetric fistulae in West Africa: patient perspectives.

OBJECTIVE: The objective of this study is to gain insight into the nature of obstetric fistulae in Africa through patient perspectives. STUDY DESIGN: At l'Hôpital Saint Jean de Dieu in Tanguieta, Benin, 37 fistula patients underwent structured interviews about fistula cause, obstacles to medical care, prevention, and reintegration by 2 physicians via interpreters. RESULTS: The majority of participants (43%) thought their fistulae were a result of trauma from the operative delivery. Lack of financial resources (49%) was the most commonly reported obstacle to care, and prenatal care (38%) was most frequently reported as an intervention that may prevent obstetric fistulae. The majority (49%) of the participants requested no further reintegration assistance aside from surgery. CONCLUSION: Accessible emergency obstetric care is necessary to decrease the burden of obstetric fistulae in Africa. This may be accomplished through increased and improved health care facilities and education of providers and patients.

Economic evaluation of surgically trained assistant medical officers in performing major obstetric surgery in Mozambique.

OBJECTIVE: To compare the training and deployment costs and surgical productivity of surgically trained assistant medical officers (técnicos de cirurgia) and specialist physicians (surgeons and obstetrician/gynaecologists) in Mozambique in order to inform health human resource planning in a developing country with low availability of obstetric care and severe physician shortages. Técnicos de cirurgia have been previously shown to have quality of care outcomes comparable to physicians. DESIGN: Economic evaluation of costs and productivity of surgically trained assistant medical officers and specialist physicians. SETTING: Hospitals and health science training institutions in Mozambique. POPULATION: Surgically trained assistants, medical officers, surgeons and obstetrician/gynaecologists in Mozambique. METHODS: The costs of training and deploying the two cadres of health workers were derived from a review of budgets, annual expenditure reports, enrolment registers, and accounting statements from training institutions and interviews with directors and administrators. Productivity estimates were based on a hospital survey of physicians and técnicos de cirurgia. MAIN OUTCOME MEASURES: Cost per major obstetric surgical procedure over 30 years in 2006 US dollars. RESULTS: The 30-year cost per major obstetric surgery was $38.9 for técnicos de cirurgia and $144.1 for surgeons and obstetrician/gynaecologists. Doubling the salaries of técnicos de cirurgia resulted in a smaller but still substantial difference in cost per surgery between the groups ($60.3 versus $144.1 per procedure). One-way sensitivity analysis to test the impact of varying other inputs did not substantially change the magnitude of the cost advantage of técnicos de cirurgia. CONCLUSION: Training more mid-level health workers in surgery can be part of the response to the health worker shortage, which today threatens the achievement of the health Millennium Development Goals in developing countries.

Reducing financial barriers to emergency obstetric care: experience of cost-sharing mechanism in a district hospital in Burkina Faso.

OBJECTIVE: To describe the implementation of a cost-sharing system for emergency obstetric care in an urban health district of Ouagadougou, Burkina Faso and analyse its results after 1 year of activity. METHODS: Service availability and use, service quality, knowledge of the cost-sharing system in the community and financial viability of the system were measured before and after the system was implemented. Different sources of data were used: community survey, anthropological study, routine data from hospital files and registers and specific data collected on major obstetric interventions (MOI) in all the hospitals utilized by the district population. Direct costs of MOI were collected for each patient through an individual form and monitored during the year 2005. Rates of MOI for absolute maternal indications (AMI) were calculated for the period 2003-2005. RESULTS: The direct cost of a MOI was on average 136US$, including referral cost. Through the cost-sharing system this amount was shared between families (46US$), health centres (15US$), Ministry of Health (38US$) and local authority (37US$). The scheme was started in January 2005. The rate of cost recovery was 91.3% and the balance at the end of 2005 was slightly positive (4.7% of the total contribution). The number of emergency referrals by health centres increased from 84 in 2004 to 683 in 2005. MOI per 100 expected births increased from 1.95% in 2003 to 3.56% in 2005 and MOI for AMI increased from 0.75% to 1.42%. CONCLUSIONS: The dramatic increase in MOI suggests that the cost-sharing scheme decreased financial and geographical barriers to emergency obstetric care. Other positive effects on quality of care were documented but the sustainability of such a system remains uncertain in the dynamic context of Burkina Faso (decentralization).

[Cost-utility analysis of surgical obstetrics in cattle with torsio uteri intra partum]. / Kosten und Nutzen der operativen Geburtshilfe bei der Torsio uteri intra partum des Rindes.

This study presents a cost-utility analysis concerning profitability of surgical obstetrics in bovines with torsio uteri intra partum. The calculations are based on 43 surgical treated cows and their postoperative outcome. Cows with torsio uteri intra partum which can not be treated conservatively are mostly, until the end of the follwing lactation period, a loss for the owner/farmer of the animal. The total loss of untreated - euthanized patients is almost 1000 euro (mainly expenses for the replacement of animals) whereas the loss of surgical treated animals, including calculated risks, is on an average 200 euro variing from -452 euro to +28 euro. The calculations presented in this study show, that the surgical treatment of conservatively incorrectable uterine torsion intra partum pays.

Management strategies for abnormal early pregnancy: a cost-effectiveness analysis.

OBJECTIVE: To assess the potential effectiveness and costs of 4 commonly used strategies to manage abnormal early pregnancies (AEPs). STUDY DESIGN: A decision analysis model was constructed to compare 4 strategies to manage AEPs: (1) observation, (2) medical management, (3) manual vacuum aspiration (MVA), and (4) dilation and curettage (D&C). RESULTS: MVA was the most cost-effective strategy, at dollar 793 per cure, for a total cost of dollar 377 million per 500,000 women and a cure rate of 95%. D&C was more effective than MVA, with a cure rate of 99%, but was more expensive (dollar 2,333 per cure, for a total cost of dollar 1.2 billion). D&C cured 20,000 more patients than MVA; however, at a substantial cost of dollar 38,925 per additional cure. With other estimates at baseline, MVA remained more cost-effective than D&C until the efficacy of MVA was < 82% or the cost of D&C was < dollar 240. CONCLUSION: MVA is the most cost-effective strategy for managing AEP and would be appropriate in settings in which resources are limited. D&C remains a reasonable strategy; however, one must spend dollar 38,925 per additional cure. In the United States, MVA would save dollar 779 million per year relative to D&C.

[A study of the unmet needs for major obstetric interventions: the experience of Burkina Faso]. / Etude des besoins obstétricaux non couverts pour les interventions obstétricales majeures: l'expérience du Burkina Faso.

The fight against maternal mortality requires strategies adapted to every socio-economic and geographic context. To define these strategies, it is essential to have relevant information and to obtain the participation of the various actors involved. One of the indicators which summarizes the maternal mortality level and which it the basis for the mobilization of resources is the maternal mortality ratio. This ratio remains difficult to measure especially in countries with limited resources. Based on the major obstetric interventions for absolute maternal indications, the unmet needs for major obstetric intervention approach is an opportunity for developing countries. We applied this approach in Burkina Faso i) to determine the number of major obstetric interventions for absolute maternal indications carried out in 1998; ii) to quantify the deficit in major obstetric interventions for absolute maternal indications carried out in 1998. In order to do this, we conducted a retrospective study based on files in four sanitary regions. Once the data was collected, we listed 610 major obstetric interventions for absolute maternal indications (IOM/IMA). For the same period, the expected number of IOM/IMA was of 1,470, i.e. a relative global deficit of 58.5%. The analysis per sanitary district revealed disparities with deficits going from 87.5% to 15.5%. The lack of qualified personnel and of surgical infrastructures, the low economic level of the populations and the high cost of the services were identified as factors having favoured these deficits.

Trends for inpatient treatment of tubal pregnancy in Maryland.

OBJECTIVE: The purpose of this study was to determine the burden of tubal pregnancy in Maryland in hospitalized patients and to elicit treatment trends. STUDY DESIGN: Patients who were admitted with tubal pregnancy from January 1, 1994, through March 31, 1999, were identified with the use of the Maryland Health Service Cost Review Commission discharge database. Combining this with census data, we calculated the incidence. Cases were then stratified by demographics, presentation, and surgeon volume. Outcome measures included type of medical treatment,conservative (salpingostomy or salpingotomy) or extirpative operation (salpingectomy, salpingo-oophorectomy, oophorectomy, hysterectomy), length of stay, charges, and disposition. The treatment groups were compared with the use of t tests and linear regression, and associations between demographics and type of operation were analyzed with logistic regression. RESULTS: The database included 3729 cases, which yielded an annual incidence of 5.2 per 10,000 women aged 15 to 45 years. Subjects averaged 29.6 years old and were predominantly African American(52.6%) and white (43.3%). Most of the women (67.8%) were seen in the emergency department and were treated surgically (90.7%). Conservative operation was performed in 18.1% of the women; extirpative operation was performed in 81.9% of the women. Significant predictors for extirpative operation were emergency department admission (odds ratio, 1.44; 95% CI, 1.18-1.75), increasing age (odds ratio, 1.07; 95% CI, 1.06-1.09), African American race (odds ratio, 1.87; 95% CI, 1.51-2.31), higher surgeon volume (odds ratio, 1.28; 95% CI, 1.04-1.57), and market area. Length of stay and total charges were higher for the extirpative group(P <.0001). The study lacked the power to detect differences in outcomes for other nonwhite races (5% power), laparoscopy versus laparotomy (15% power), or operating room charges (14% power). CONCLUSION: These data are limited to hospitalized patients and probably underestimate the true incidence of tubal pregnancy. Most patients underwent extirpative operation. Acuity of presentation and increasing age were appropriate predictors of this group. However, physician volume and black race were also predictors. This may be due to differences in the prevalence of disease, unmeasured clinical factors, patient and physician preferences for treatment, barriers that delayed care, or other socioeconomic factors.

Measuring cost-effectiveness of surgical procedures.

Our review of CEA of surgical procedures suggests that much of the existing cost analysis literature does not adhere to basic recommended analytic guidelines. However, those authors who specifically planned to perform a CEA analysis met all or nearly all of the methodologic principles (Table 1). Investigators who conduct CEA are strongly encouraged to use the many outstanding methodologic reviews for CEA. An example of threshold analysis was presented by Gray et al in their CEA of laparoscopy versus laparotomy for the treatment of ectopic pregnancy. They calculated that cost per successful treatment would be equal between the two strategies at an initial failure rate of 32% for laparoscopy (compared with their baseline value of 19%). This type of analysis is helpful, in addition to sensitivity analyses, to identify the value of a variable that results in an equal outcome. In the only cost-utility analysis performed on gynecologic surgery, Sculpher studied the trade-offs between a less invasive, less costly procedure (transcervical resection of the endometrium) with a more invasive, more costly, and more effective procedure (abdominal hysterectomy) to treat menorrhagia. Hysterectomy resulted in an incremental cost of 1,500 British pounds per QALY during 2 years of follow-up. This is much less than the range of $30,000 to $100,000 that represents a currently acceptable C/E ratio. Grover et al evaluated the cost-effectiveness of performing a concurrent hysterectomy in women undergoing bilateral salpingo-oophorectomy. They observed that in 45-year-old women, the additional concurrent procedure dominated the alternative strategy of bilateral salpingo-oophorectomy, being both less expensive and increasing average life expectancy. The concurrent hysterectomy strategy also dominated for women aged 55, but both with less cost-savings and gains in life expectancy compared with 45-year-old women. Selecting an appropriate time frame for the analysis is difficult and may dramatically affect the results of the analysis. The time frame should be long enough to measure all clinically relevant costs and benefits. For example, Kung et al compared the cost per cure of stress urinary incontinence of laparoscopic and open Burch procedures. The probability of cure after each procedure was estimated from a retrospective cohort of 62 women with a mean follow-up of 1.2 years for the laparoscopic Burch strategy and 2.7 years in the open Burch strategy. The authors found that the laparoscopic Burch dominated, with lower costs and a higher cure rate. However, the analysis would be more informative with much longer follow-up, because most women who undergo an incontinence procedure have a life expectancy far greater than 1 to 2 years. Ramsey et al performed an economic analysis to assess the long-term costs of behavioral therapy, pharmacotherapy, and surgical therapy used for stress urinary incontinence. They found that in the short-term, behavioral and pharmacotherapy were less costly. However, if life expectancy was equal to or greater than 3.5 years, surgical therapy was least costly. In many articles that evaluate the cost of managing ectopic pregnancy, only short-term costs of the procedures and follow-up visits are considered. Mol et al considered a longer time frame and also included the costs of infertility management based on the future probability of conception correlated with the different management strategies. Selection of an effectiveness measure after surgical intervention is often difficult and controversial. For benign disease, life years or QALYs will be minimally affected by a reasonably safe intervention. In the short-term, utility may be negatively affected by surgery and recovery. In longer-term analyses, these effects will be diluted by time and be negligible. Intermediate measures such as days of hospitalization averted or lives saved are often more appropriate for gynecologic interventions than are longer-term outcomes such as lif

Out-of-pocket expenses borne by the users of obstetric services at government hospitals in Karachi, Pakistan.

OBJECTIVE: Financing health services is a challenge for health policy makers world over, especially in developing countries. Alternate mechanisms such as user fees are being proposed. However, there is a feeling that in developing countries, users of government hospitals spend appreciable personal income to obtain "free services" at these facilities. METHODS: This study aimed to measure the extent and the factors associated with of out-of-pocket expenses borne by the users of obstetric care at government hospitals. It also aimed to determine willingness of consumers to bear out of pocket expenses. It was conducted in three government hospitals in Karachi. RESULTS: Seven hundred cases were registered in the study. Sixty-five percent of them had a monthly household income of less than Rupees (Rs.) 3000. Overall, users spent mean of Rs. 590 as out-of-pocket expenses for obstetric services. Of this Rs. 330 was spent on drugs and Rs. 24 on user fees. Thirty-nine percent of the patients were willing to spend out of pocket for services provided at government hospital and 39% declined to do so. Of the patients indicating willingness to spend, 98% agreed to do so for drugs. CONCLUSION: The results suggest that considerable expenses are borne out of pocket by the users of government hospitals for supposedly "free services". If user fees are to be increased the government needs to provide services for which the people will pay, such as drugs, otherwise increase in this fees will simply add to financial burden on the users.
