Overactive Bladder Medication Adherence When Medication is Free to Patients

PURPOSE We examined overactive bladder medication compliance in a health care system in which patients do not pay for medication. MATERIALS AND METHODS Pharmacy dispensing records were reviewed for antimuscarinic agents from January 2003 to December 2006 for the United States Military Health System National Capital Region. Medication nonpersistence, switching and adherence were examined. Kaplan-Meier survival analysis was done to compare medication persistence duration. RESULTS Overactive bladder medications were dispensed to 7,879 adults. Tolterodine extended release (4,716 patients or 60%) and oxybutynin immediate release (2,003 or 25.5%) were most commonly prescribed. The medication nonpersistence rate, defined as the proportion of patients who never refilled a prescription for antimuscarinics during the study period, was 35.1% (2,760 of 7,858). Of 5,098 patients who refilled a prescription 1,305 changed the medication or dose at least once for a medication switch rate of 25.6%. The overall median medication possession ratio, defined as the total days of medication dispensed except for the last refill divided by the number of days between the first dispense date and the last refill date, was 0.82 in all cases. Men had a significantly higher median medication possession ratio than women (0.86 vs 0.81, p <0.001). Of patients who obtained at least 1 refill women remained on medication longer than men (median 606 vs 547 days, p = 0.01). Patients on tolterodine extended release had a higher medication nonpersistence rate than those on oxybutynin immediate release (0.89 vs 0.68, p <0.01). There was no difference between extended release medications. CONCLUSIONS In a health care system in which patients do not pay for medications 35% of patients did not refill a prescription for overactive bladder medication, similar to previous reports. However, other measures of medication compliance were higher than those published previously in systems with copays.

The Racial Distribution of Female Pelvic Floor Disorders in an Equal Access Health Care System

PURPOSE We examined ethnic differences in female pelvic disorders in an equal access health care system. MATERIALS AND METHODS An electronic medical record review was performed for patients with pelvic floor disorders at a military female pelvic medicine and reconstructive surgery division for a 1-year period. Primary diagnosis codes and patient reported race were reviewed. RESULTS Mean +/- SD cohort age was 55 +/- 16.3 years. A total of 720 patients were identified, of whom 68.8% were white and 18.6% were black. Pelvic organ prolapse was the primary diagnosis in 34.2% of the women, while 19.7% had stress urinary incontinence and 10.8% had urge urinary incontinence. There was no difference in the prevalence of prolapse between black and white women. However, of patients with incontinence there was a statistically significant difference with urge incontinence in more black women (51.2%) and stress incontinence in more white women (66.2%) (chi-square p <0.05). CONCLUSIONS There is a similar ethnic distribution of pelvic organ prolapse in an equal access health care system. Of women with incontinence there was a higher prevalence of urge urinary incontinence in black women and a higher prevalence of stress urinary incontinence in white women.

Pregnancy during Operation Iraqi Freedom/Operation Enduring Freedom

OBJECTIVE The purpose of this study was to evaluate pregnancy during war-time deployment. METHODS A retrospective review of gynecology visits was evaluated at Camp Doha, Kuwait, from August 2003 through April 2004. Of the 1,737 visits, 77 demonstrated a positive pregnancy test. These charts were evaluated for factors that may lead to important information for future deployments. RESULTS The average age of the female soldier with a positive pregnancy test in theater was 27 +/- 7 years. The primary presenting complaint was amenorrhea. Ninety-two percent had an ultrasound. Fifty-four percent of visits were active duty, followed by Reserve, National Guard, and civilian government employees. Ninety-two percent were administratively redeployed. Seventy-seven percent of the soldiers became pregnant in country. Twenty-three percent arrived in country pregnant. CONCLUSIONS Given the number of pregnancies before and during deployment, current screening procedures as well as new concepts in prevention need to be addressed.

Acute Dysuria among Female Soldiers

OBJECTIVE To assess behavior patterns among active duty female soldiers presenting to military care facilities for acute dysuria. METHODS A self-administered questionnaire was developed. One hundred twelve female soldiers presenting with acute dysuria and one hundred twenty-six presenting for other reasons were surveyed. RESULTS During regular duty hours, the dysuria group drank less than the control group (21% and 14%, respectively; p = 0.004). However, field duty appeared to compound this problem, with the dysuria group drinking considerably less than the control group (79% and 19%, respectively; p = 0.002). Both groups stated that they postponed urination during working hours. The dysuria group postponed urination more than did the control group during regular duty (75% and 53%, respectively; p = 0.006) and field duty (79% and 65%, respectively; p = 0.008). CONCLUSIONS Female soldiers presenting with dysuria were more likely to report fluid restriction and to postpone voiding during duty, behaviors that were reported even more frequently during field duty. Fluid restriction and postponed urination may be significant factors in the development of acute dysuria among female soldiers.

Sexually Transmitted Diseases in Operation Iraqi Freedom/Operation Enduring Freedom

OBJECTIVE To identify the incidence of sexually transmitted diseases (STDs) in a female active duty population deployed in support of Operation Iraqi Freedom/Operation Enduring Freedom was the objective of this study. METHODS Retrospective chart review was completed on all soldiers seeking outpatient gynecologic care at Camp Doha, Kuwait, from September 2003 through March 2004. Descriptive statistical analysis was performed on data from all patients identified as having an STD. RESULTS Forty-four soldiers (2.5% of all encounters) were diagnosed with STDs during the study period. Genital herpes, Condyloma acuminata, and chlamydia were the most commonly identified infections accounting for 30, 25, and 21% of the diagnoses, respectively. CONCLUSION Transmission of STDs in the deployed environment continues to be problematic. Viral infections were more commonly encountered than were bacterial infections. Patient education and prevention should be emphasized. Consideration should be given to STD screening upon redeployment.

Pelvic Pain Presenting in a Combat Environment

OBJECTIVE The objective was to identify the incidence of pain disorders in the deployed female active duty population in support of Operation Iraqi Freedom. METHODS Retrospective chart review was completed on all patients who were seen for gynecologic services at Camp Doha, Kuwait, from September 2003 through March 2004. One thousand seven hundred thirty-seven patients were identified. Statistical analysis was performed. RESULTS Of the 1,737 patients seen during the study period, 150 patients were identified as having a pelvic pain disorder. These patients accounted for 14% of all patients seen for gynecologic services. Mean age was 28 +/- 8 years (range, 15-53 years). Pelvic pain of unclear etiology and cystitis were the most common diagnoses made accounting for 19% and 16% of encounters. CONCLUSIONS Acute pelvic pain disorders can be effectively managed in the combat environment. Optimization of predeployment regimens for management of pain is strongly recommended. Consideration should be given to making soldiers with chronic pelvic pain disorders that fail to respond to predeployment medical management nondeployable.

Utility of ultrasound in the combat theater : Experiences of a gynecologist during operation iraqi freedom/operation enduring freedom

OBJECTIVE The purpose of this study was to evaluate the utility of ultrasound in a combat theater. METHODS A retrospective review of gynecology visits was evaluated at Camp Doha, Kuwait, from August 2003 through April 2004. Of the 1,737 visits, 237 required pelvic ultrasound. Demographic information, as well as the indications, diagnosis, and disposition of the patients, was compiled. RESULTS The average age of the patient requiring ultrasound was 28 +/- 8 years. The primary presenting complaint was pelvic pain. Forty percent with pelvic pain had no identifiable cause. The most common final diagnosis was pregnancy. Of the 237 visits, the use of ultrasound resulted in 136 return-to-duty dispositions. Of the 31% who were administratively redeployed, the majority were secondary to pregnancy. CONCLUSION Gynecologic ultrasound was found to be a very useful tool in the combat theater. Ultrasound resulted in improved diagnostic ability and enhanced reassurance to both provider and patient.
