ABSTRACT

OBJECTIVES: This study evaluated a collaborative service model between the largest Medicaid managed care organization (MCO) in Texas, Superior HealthPlan, and the affordable housing provider Prospera Housing Community Services. STUDY DESIGN: Using a quasi-experimental 2-groups research design, we compared health care outcomes and costs between a sample of 104 participants served by the Prospera+Superior collaborative model and a group of 104 participants who had health care coverage through the Superior HealthPlan Medicaid MCO but did not live at Prospera properties (ie, Superior-only group). METHODS: Data from medical claims were analyzed to examine change in outcomes 12 months before and after implementation of the Prospera+Superior collaborative model in 2019. RESULTS: The Prospera+Superior group had a 56% lower rate of emergency department/urgent care visits and spent $2061 less in prescription costs than the Superior-only group after implementation. CONCLUSIONS: These findings provide needed evidence of the clinical and economic value of forming multisector collaborative models between MCOs and other community providers.

ABSTRACT

Importance: Risk-adjusted neonatal intensive care unit (NICU) utilization and outcomes vary markedly across regions and hospitals. The causes of this variation are poorly understood. Objective: To assess the association of hospital-level NICU bed capacity with utilization and outcomes in newborn cohorts with differing levels of health risk. Design, Setting, and Participants: This population-based retrospective cohort study included all Medicaid-insured live births in Texas from 2010 to 2014 using linked vital records and maternal and newborn claims data. Participants were Medicaid-insured singleton live births (LBs) with birth weights of at least 400 g and gestational ages between 22 and 44 weeks. Newborns were grouped into 3 cohorts: very low birth weight (VLBW; <1500 g), late preterm (LPT; 34-36 weeks' gestation), and nonpreterm newborns (NPT; ≥37 weeks' gestation). Data analysis was conducted from January 2022 to October 2023. Exposure: Hospital NICU capacity measured as reported NICU beds/100 LBs, adjusted (ie, allocated) for transfers. Main Outcomes and Measures: NICU admissions and special care days; inpatient mortality and 30-day postdischarge adverse events (ie, mortality, emergency department visit, admission, observation stay). Results: The overall cohort of 874 280 single LBs included 9938 VLBW (5054 [50.9%] female; mean [SD] birth weight, 1028.9 [289.6] g; mean [SD] gestational age, 27.6 [2.6] wk), 63 160 LPT (33 684 [53.3%] female; mean [SD] birth weight, 2664.0 [409.4] g; mean [SD] gestational age, 35.4 [0.8] wk), and 801 182 NPT (407 977 [50.9%] female; mean [SD] birth weight, 3318.7 [383.4] g; mean [SD] gestational age, 38.9 [1.0] wk) LBs. Median (IQR) NICU capacity was 0.84 (0.57-1.30) allocated beds/100 LB/year. For VLBW newborns, NICU capacity was not associated with the risk of NICU admission or number of special care days. For LPT newborns, birth in hospitals with the highest compared with the lowest category of capacity was associated with a 17% higher risk of NICU admission (adjusted risk ratio [aRR], 1.17; 95% CI, 1.01-1.33). For NPT newborns, risk of NICU admission was 55% higher (aRR, 1.55; 95% CI, 1.22-1.97) in the highest- vs the lowest-capacity hospitals. The number of special care days for LPT and NPT newborns was 21% (aRR, 1.21; 95% CI,1.08-1.36) and 37% (aRR, 1.37; 95% CI, 1.08-1.74) higher in the highest vs lowest capacity hospitals, respectively. Among LPT and NPT newborns, NICU capacity was associated with higher inpatient mortality and 30-day postdischarge adverse events. Conclusions and Relevance: In this cohort study of Medicaid-insured newborns in Texas, greater hospital NICU bed supply was associated with increased NICU utilization in newborns born LPT and NPT. Higher capacity was not associated with lower risk of adverse events. These findings raise important questions about how the NICU is used for newborns with lower risk.

ABSTRACT

PURPOSE: This study was designed to provide a comprehensive and up-to-date understanding of population-level reoperation rates and incremental healthcare costs associated with reoperation for patients who underwent breast-conserving surgery (BCS). METHODS: This is a retrospective cohort study using Merative™ MarketScan® commercial insurance data and Medicare 5% fee-for-service claims data. The study included females aged 18-64 years in the commercial cohort and females aged 18 years and older in the Medicare cohort, who underwent initial BCS for breast cancer in 2017-2019. Reoperation rates within a year of the initial BCS and overall 1-year healthcare costs stratified by reoperation status were measured. RESULTS: The commercial cohort included 17,129 women with a median age of 55 (interquartile range [IQR] 49-59) years, and the Medicare cohort included 6977 women with a median age of 73 (IQR 69-78) years. Overall reoperation rates were 21.1% (95% confidence interval [CI] 20.5-21.8%) for the commercial cohort and 14.9% (95% CI 14.1-15.7%) for the Medicare cohort. In both cohorts, reoperation rates decreased as age increased, and conversion to mastectomy was more prevalent among younger women in the commercial cohort. The mean healthcare costs during 1 year of follow-up from the initial BCS were $95,165 for the commercial cohort and $36,313 for the Medicare cohort. Reoperations were associated with 24% higher costs in both the commercial and Medicare cohorts, which translated into $21,607 and $8559 incremental costs, respectively. CONCLUSIONS: The rates of reoperation after BCS have remained high and have contributed to increased healthcare costs. Continuing efforts to reduce reoperation need more attention.

ABSTRACT

Importance: The Hospital-Acquired Condition Reduction Program (HACRP) evaluates acute care hospitals on the occurrence of patient safety events and health care-associated infections. Since its implementation, several studies have raised concerns about the overpenalization of teaching and safety-net hospitals, and although several changes in the program's methodology have been applied in the last few years, whether these changes reversed the overpenalization of teaching and safety-net hospitals is unknown. Objective: To determine hospital characteristics associated with HACRP penalization and penalization reversal. Design, Setting, and Participants: This retrospective cross-sectional study assessed data from 3117 acute care hospitals participating in the HACRP. The HACRP penalization and hospital characteristics were obtained from Hospital Compare (2020 and 2021), the Inpatient Prospective Payment System impact file (2020), and the American Hospital Association annual survey (2018). Exposures: Hospital characteristics, including safety-net status and teaching intensity (no teaching and very minor, minor, major, and very major teaching levels). Main Outcomes and Measures: The primary outcome was HACRP penalization (ie, hospitals that fell within the worst quartile of the program's performance). Multivariable models initially included all covariates, and then backward stepwise variable selection was used. Results: Of 3117 hospitals that participated in HACRP in 2020, 779 (25.0%) were safety-net hospitals and 1090 (35.0%) were teaching institutions. In total, 771 hospitals (24.7%) were penalized. The HACRP penalization was associated with safety-net status (odds ratio [OR], 1.41 [95% CI, 1.16-1.71]) and very major teaching intensity (OR, 1.94 [95% CI, 1.15-3.28]). In addition, non-federal government hospitals were more likely to be penalized than for-profit hospitals (OR, 1.62 [95% CI, 1.23-2.14]), as were level I trauma centers (OR, 2.05 [95% CI, 1.43-2.96]) and hospitals located in the New England region (OR, 1.65 [95% CI, 1.12-2.43]). Safety-net hospitals with major teaching levels were twice as likely to be penalized as non-safety-net nonteaching hospitals (OR, 2.15 [95% CI, 1.14-4.03]). Furthermore, safety-net hospitals penalized in 2020 were less likely (OR, 0.64 [95% CI, 0.43-0.96]) to revert their HACRP penalization status in 2021. Conclusions and Relevance: Findings from this cross-sectional study indicated that teaching and safety-net hospital status continued to be associated with overpenalization in the HACRP despite recent changes in its methodology. Most of these hospitals were also less likely to revert their penalization status. A reevaluation of the program methodology is needed to avoid depleting resources of hospitals caring for underserved populations.

ABSTRACT

BACKGROUND: We sought to describe patient characteristics in adults with and without congenital heart defects (CHDs) during hospitalization for COVID-19. METHODS: We analyzed data collected by Optum®, a nationally representative database of electronic medical records, for 369 adults with CHDs and 41,578 without CHDs hospitalized for COVID-19 between January 1, 2020, and December 10, 2020. We used Poisson regression to describe and compare epidemiologic characteristics, heart-related conditions, and severe outcomes between these two groups. RESULTS: The distributions of many epidemiologic characteristics were similar between the two groups, but patients with CHDs were significantly more likely to be current or former smokers compared to patients without CHDs (risk ratio [RR]: 1.5, 95% confidence interval [CI]: 1.2, 1.8). Patients with CHDs were also significantly more likely to have heart failure, stroke, acute arrhythmia, myocardial injury, acute pulmonary hypertension, venous thromboembolism, and obesity documented at the time of the COVID-19 hospitalization (RR range: 1.5-4.7) but not respiratory failure. Patients with CHDs (7 days) had a significantly longer median length of stay than those without CHDs (5 days; p < .001) and were significantly more likely to have an intensive care unit (ICU) admission (RR: 1.6, 95 CI: 1.2-1.9). CONCLUSIONS: Our description of patients among a large population improves our understanding of the clinical course of COVID-19 among adults with CHDs. Adults with CHD appear to be at greater risk for more severe CHD, including greater risk of ICU admission and longer length of hospital stays.

ABSTRACT

To examine temporal trends of NICU admissions in the U.S. by race/ethnicity, we conducted a retrospective cohort analysis using natality files provided by the National Center for Health Statistics at the U.S. Centers for Disease Control and Prevention. A total of 38,011,843 births in 2008-2018 were included. Crude and risk-adjusted NICU admission rates, overall and stratified by birth weight group, were compared between white, black, and Hispanic infants. Crude NICU admission rates increased from 6.62% (95% CI 6.59-6.65) to 9.07% (95% CI 9.04-9.10) between 2008 and 2018. The largest percentage increase was observed among Hispanic infants (51.4%) compared to white (29.1%) and black (32.4%) infants. Overall risk-adjusted rates differed little by race/ethnicity, but birth weight-stratified analysis revealed that racial/ethnic differences diminished in the very low birth weight (< 1500 g) and moderately low birth weight (1500-2499 g) groups. Overall NICU admission rates increased by 37% from 2008 to 2018, and the increasing trends were observed among all racial and ethnic groups. Diminished racial/ethnic differences in NICU admission rates in very low birth weight infants may reflect improved access to timely appropriate NICU care among high-risk infants through increasing health care coverage coupled with growing NICU supply.

ABSTRACT

OBJECTIVE: To test the hypothesis that newborn infants cared for in hospitals with greater utilization of neonatal intensive care experienced fewer postdischarge adverse events. STUDY DESIGN: We developed 3 retrospective population-based cohorts of Texas Medicaid insured singletons born in 2010-2014 (very low birth weight [VLBW n = 11 139], late preterm [n = 57 509], and non-preterm [n = 664 447]) who received care in higher volume hospitals with level III/IV neonatal intensive care units (NICUs). Measures of NICU care were hospital-level risk adjusted NICU admission rates, special care days (days of nonroutine care) per infant, and the percent of intensive (highest billable care code) special care days. The units of analysis were hospitals (n = 80) and the primary outcome was an adverse event, (defined as admission, emergency department visit, or death) within 30 days postdischarge. RESULTS: Higher use of NICU care at a hospital level was not associated with lower postdischarge 30-day adverse event. Infants cared for in hospitals with above vs below median special care day rates experienced slightly higher postdischarge adverse event per 100 infants (VLBW: 14.01 [95% CI 12.74-15.27] vs 11.84 [10.52-13.16], P < .05; late preterm: 7.33 [6.68-7.97] vs 6.28 [5.87-6.69], P < .01; non-preterm: 4.47 [4.17-4.76] vs 3.97 [3.75-4.18], P < .01). Weak positive associations (Pearson correlations of 0.31-0.37, P < .01) were observed for adverse event with special care days; in no instance was a negative association observed between NICU utilization and adverse event. CONCLUSION: Higher utilization of NICU care was not associated with lower rates of short-term events suggesting that there may be opportunities to safely decrease admission rates and length of NICU stays.

ABSTRACT

BACKGROUND: The proportion of deaths attributed to various causes has not been quantified among infants with birth defects. We sought to describe the causes of neonatal and postneonatal death among infants in the Texas Birth Defects Registry. METHODS: We calculated frequencies and percentages for both underlying causes and all causes (underlying or contributing) of neonatal (0-27 days) and postneonatal (28-364 days) death listed on death certificates among infants born alive with birth defects and delivered in Texas during 1999-2013 (n = 8,389 deaths). Analyses were repeated separately for infants with isolated, multiple, and syndromic defects. RESULTS: After birth defects, the most frequently listed causes of neonatal death were preterm/low birth weight (10%), circulatory system diseases (8%), and sepsis (5%). The leading postneonatal causes of death beyond birth defects were circulatory system diseases (32%), sepsis (11%), and renal failure (7%). CONCLUSIONS: Improved understanding of the causes of mortality among infants with birth defects may help identify priorities for postnatal care. Our results suggest that potentially modifiable causes of death (e.g., circulatory system diseases, sepsis) contribute substantially to mortality in this population. Prioritizing continued improvements in prevention, diagnosis, and management of preventable conditions may reduce mortality among infants born with birth defects.

ABSTRACT

BACKGROUND: The success of neonatal intensive care in improving outcomes for critically ill neonates led to rapid growth of NICU use in the United States, despite a relatively stable birth cohort. Less is known about NICU use among late-preterm and term infants, although recent studies have observed wide variation in their care patterns. In this study, we measure special care days (SCDs) (intermediate or intensive), length of stay, and readmission rates among low-risk neonates across regions within 2 states. METHODS: In this retrospective cohort study, we analyzed data from Massachusetts (all payer claims) and Texas (BlueCross BlueShield) from 2009 to 2012. A low-risk cohort was defined by identifying newborns with diagnostic codes indicating a gestational age ≥35 weeks and birth weight ≥1500 g and excluding infants with diagnoses and procedures generally necessitating nonroutine care. Outcomes were measured across neonatal intensive care regions by diagnosis and payer type. RESULTS: We identified 255 311 low-risk newborns. SCD use varied nearly sixfold across neonatal intensive care regions. Use was highest among commercially insured Texas infants (8.42 per 100), followed by Medicaid-insured Massachusetts infants (6.67 per 100) and commercially insured Massachusetts infants (5.15 per 100). Coefficients of variation indicated high variation within each payer-specific cohort and moderate to high variation across each condition. No consistent relationship between regional SCD use and 30-day readmissions was identified. CONCLUSIONS: Use of NICU services varied widely across regions in this cohort of low-risk infants. Further investigation is needed to delineate outcomes associated with patterns of care received by this population.

ABSTRACT

OBJECTIVE: To assess the contribution of maternal and newborn characteristics to variation in neonatal intensive care use across regions and hospitals. STUDY DESIGN: This was a retrospective population-based live birth cohort of newborn infants insured by Texas Medicaid in 2010-2014 with 2 subcohorts: very low birth weight (VLBW) singletons and late preterm singletons. Crude and risk-adjusted neonatal intensive care unit (NICU) admission rates, intensive and intermediate special care days, and imaging procedures were calculated across Neonatal Intensive Care Regions (n = 21) and hospitals (n = 100). Total Medicaid payments were calculated. RESULTS: Overall, 11.5% of live born, 91.7% of VLBW, and 37.6% of infants born late preterm were admitted to a NICU, receiving an average of 2 days, 58 days, and 5 days of special care with payments per newborn inpatient episode of $5231, $128 075, and $10 837, respectively. There was little variation across regions and hospitals in VLBW NICU admissions but marked variation for NICU admissions in late preterm newborn infants and for special care days and imaging rates in all cohorts. The variation decreased slightly after health risk adjustment. There was moderate substitution of intermediate for intensive care days across hospitals (Pearson r VLBW -0.63 P < .001; late preterm newborn -0.53 P < .001). CONCLUSIONS: Across all risk groups, the variation in NICU use was poorly explained by differences in newborn illness levels and is likely to indicate varying practice styles. Although the "right" rates are uncertain, it is unlikely that all of these use patterns represent effective and efficient care.

ABSTRACT

OBJECTIVE: Assess temporal trends in congenital microcephaly. METHODS: We used Texas inpatient discharge diagnoses between 2000 and 2015, restricting to newborns. Between 2000 and 2003, the maximum number of fields for recording diagnostic codes was eight, and between 2004 and 2015 it was 24. Microcephaly was classified into four subgroups based on co-occurring diagnoses: A (Known Causes), B (Other Birth Defects), C (Preterm Birth or Fetal Growth Restriction) and D (Isolated Cases). RESULTS: We identified 2,301 cases of microcephaly or 4.0 cases per 10,000 live births. There was an increase in the prevalence of microcephaly in 2012-2015 compared with 2000-2003, odds ratio = 1.85 (95% CI 1.64-2.10) Significant temporal increases in microcephaly were observed within each of the four microcephaly subgroups and significant temporal increases were also observed for eight other neonatal diagnoses during the same time period. When we restricted our analysis to cases with microcephaly identified using only the eight diagnostic codes available throughout the entire study period, the temporal trend for microcephaly was diminished or absent. CONCLUSIONS: It remains uncertain whether the observed increases in microcephaly and other neonatal diagnoses are real or an artifact of the change in the number of fields. However, since it is unlikely that there would be a simultaneous increase in microcephaly and eight other neonatal diagnoses, it is likely that some or all of the temporal increases in neonatal diagnoses are artifactual.

ABSTRACT

According to national guidelines and statements drugs that can cause or exacerbate heart failure (HF) are considered potentially harmful and should be avoided if possible in patients with a diagnosis of heart failure with reduced ejection fraction (HFREF). To evaluate the prevalence of potentially harmful drug (PHD) prescription among patients with a diagnosis of systolic heart failure we conducted a retrospective cohort study using Truven Health MarketScan Commercial database from 2011 to 2014. Prescription of PHD as defined by American Heart Association Statement was examined among patients with a HFREF diagnosis in: (1) Two outpatient encounters, (2) One inpatient encounter as primary diagnosis and/or (3) one inpatient encounter any position and one outpatient encounter. Among 40,966 patients, 24.2% were prescribed with at least 1 drug with the potential to cause or exacerbate heart failure. Of the 9,954 patients prescribed with PHD, nonsteroidal anti-inflammatory agents were the most frequent category prescribed (67.4%), followed by antihypertensive (24%), diabetes mellitus (23.3%), neurological and psychiatric (21%) and antiarrhythmic medications (12.6%). After multivariable analysis female patients, the presence of a comorbidity associated with a PHD use and polypharmacy were more frequently prescribed a PHD. In conclusion almost » of adult patients with a diagnosis of HFREF have a prescription of a drug with a potential to cause or exacerbate heart failure as defined by current heart failure guidelines.

ABSTRACT

OBJECTIVE: Estimate inpatient hospitalization costs for patients with microcephaly, and predict cost increases due to a potential Zika virus outbreak. METHODS: We identified Texas-wide inpatient hospitalization discharge records (2008-2015), for newborns and non-newborns with microcephaly. We estimated the cost of each hospitalization by applying cost-to-charge ratios on the actual hospitalization charge. For comparison, newborn visits for patients without microcephaly were also identified, and hospital costs were compared between patients with and without microcephaly. We estimated costs for microcephaly during the first year of life following a Zika outbreak (possible 1-50% increase in birth prevalence) in Texas. RESULTS: There were 8005 microcephaly hospitalizations ($203,899,042; total cost). The median admission cost for newborns with microcephaly (N = 1393) was higher compared to those without microcephaly ($6751 vs $725, p < 0.001). Microcephaly hospitalizations of newborns had a lower median cost compared to non-newborns ($6751 vs $9754, p < 0.001). Based on these observed hospitalization costs, we estimated that a potential Zika virus outbreak in Texas could result in an additional $1-6 million per year for hospitalizations. CONCLUSION: Hospitalizations of patients with microcephaly are associated with high costs. An increase in microcephaly prevalence due to a Zika outbreak in Texas could have a considerable impact on health care costs.

ABSTRACT

BACKGROUND: Newborn care is one of the most frequent types of hospitalization and Medicaid covers over 50% of all births nationwide. However, little is known about regional variation in Medicaid newborn care spending and its drivers. OBJECTIVES: To measure the contribution of market-level prices, utilization, and health risk on regional variation in spending among newborn Medicaid population in Texas. RESEARCH DESIGN AND METHODS: The study used 2014 Texas Medicaid newborn claims and encounters linked to birth and death certificate data. Newborn care spending was defined as Medicaid payments per newborn hospital stay, including hospital transfers, from birth through discharge home or death. Spending was further categorized into inpatient facility and related professional spending. Variation in spending across neonatal intensive care regions was decomposed into price and utilization, accounting for input price and health risk differences. RESULTS: Newborn care spending across Texas regions varied significantly (coefficient of variation, 0.31), with most of the variation attributed to spending on inpatient facility services (91%). Both price (41%) and utilization (27%) played a role in explaining this variation, after adjusting for health status (29%) and input price (4%). Though most regions with the highest spending indexes had high price and utilization indexes, some had high spending driven mostly by high prices and others by high utilization. CONCLUSIONS: Significant regional variations in price, utilization, and health status exist in Medicaid newborn care across Texas in 2014. Disentangling the effect of each driver is important to address spending variation and improve efficiency in newborn care.

ABSTRACT

The Healthcare Effectiveness Data and Information Set (HEDIS) is used by health plans to measure and report on quality and performance. This study evaluated the appropriateness of the prescription drug compliance step for the Medical Attention for Nephropathy quality measure for patients with diabetes. Data from national commercial claims for 28,348,363 persons were reviewed. The study applied the standard HEDIS specifications for compliance in medical attention for nephropathy for diabetic patients. Evaluation of the third and final process (evidence of angiotensin-converting enzyme [ACE] inhibitors or angiotensin II receptor blockers [ARBs]) found that the addition of this step contributed 14% to 16% of the numerator, bringing the final rate to the >80% range. Yet, presence of a prescription for an ACE inhibitor or ARB did not confirm microalbuminuria. Only 1% of the persons satisfying Step 3 had evidence of microalbuminuria in years prior and none in the reporting year. Use of these medications does not obviate the need for a nephropathy screening in diabetics. Inclusion of these medications as numerator compliance leads to overreporting and may contribute to underscreening of a population at risk.

ABSTRACT

BACKGROUND: Silent-members are members of a medical health plan who submit no claims for healthcare services in a benefit year despite 12 months of continuous-enrollment. This study was conducted to evaluate the future expenditure risk of commercial-insured members who avoid all medical care despite coverage. In order to determine if the silent-members were at greater risk, we compared them to members who received care in the anchor year (2009) but had low-expenditures. The low-expenditure members were assumed to represent persons without significant medical conditions and without care-avoidance behaviors. We examined the claims experience of a cohort of silent members in the 2 years after the silent year (2009) and compared it with the corresponding claims experience for a cohort of low-expenditure members from the same anchor year (2009). METHODS: Members of commercial health plans (BCBS of Texas) were selected based on continuous-enrollment in 2009. Two sub-groups were identified based on annual claims expenditure: Care avoiders were members with 12 months continuous-enrollment and no medical claims, and are thus referred to as "silent members" in the insurance industry. Low-Expenditure members were those with 12 months continuous-enrollment and total PMPY (per member per year) annual medical claims expenditure in the lowest 10th percentile of members with claims experience. "Low-expenditure" members served as a comparison group to the "silent members", under the assumption that such claimants were using benefits for minor healthcare issues as needed. Key variables were enrollment and expenditures. Enrollment data identified demographics and continuous-enrollment. Medical claims data were used to calculate utilization and expenditures. All claims data were de-identified and no consent was required, as approved by the Institutional Review Board. No research involved human subjects. Multivariate logistic regression models were applied. RESULTS: Silent members who seek care in subsequent years have a greater probability of becoming high-expenditure claimants than those with low-expenditure experience. CONCLUSIONS: For silent members who subsequently seek treatment, the probability of becoming high-expenditure is significantly greater than low-expenditure members from the anchor year. The implications of future high costs for silent members who become claimants may support the need for additional research to address the risks of care avoidance behaviors.

ABSTRACT

Data on the long-term outcomes of the use of fixed-dose combinations (FDCs) or free-pill combinations (FPCs), titration of doses, and switching are currently unavailable for identifying a preferred strategy for adherence. In the lack of these evidences, adherence can be a useful guiding criteria. The authors conducted a retrospective cohort study using the BlueCross BlueShield of Texas (2008-2012) database to compare adherence among 5998 patients who received treatment modifications (TMs). Results of the propensity score-adjusted model indicate that FDC and uptitration strategies have higher odds of adherence compared with the switch strategy (P<.05). Among patients with a history of poor adherence, the odds of adherence were up to 26% higher for the FDC strategy compared with alternative strategies (P<.05). Factors including age, number of comedications, first-line drug class, and health services utilization are associated with adherence. In conclusion, FDCs should be prioritized for TM, particularly if the patient has a history of poor adherence.

ABSTRACT

OBJECTIVES: Treatment modifications--addition, uptitration, switching, and downtitration--are necessary to address issues such as unattained blood pressure goals, adverse drug events, drug cost, or patient dissatisfaction which lead to treatment discontinuation. This study assessed the patterns of treatment modifications, and compared the rates of treatment modification and time-to-treatment modification across five antihypertensive drug classes (ADCs). Additionally, the association between treatment modification strategies and the likelihood of treatment discontinuation was assessed. METHODS: This is a retrospective cohort study using the BlueCross-BlueShield of Texas commercial claims database (2008-2012). Treatment modifications that occurred within 1 year of starting hypertension treatment were identified. Patients who received treatment modifications were followed for 12 months to determine if and when they discontinued treatment. Cox regression models were used to determine the likelihood of treatment modification and treatment discontinuation. RESULTS: About 48.5% of patients received treatment modifications within 1 year of treatment initiation. Rates of treatment modification were significantly different across ADCs; angiotensin-converting enzyme inhibitor and angiotensin receptor blocker users were less likely to receive treatment modifications compared with other ADCs. Mean time-to-treatment modification was more than 100 days for adding and uptitrating, and more than 140 days for switching and downtitrating. Patients intensifying treatment by adding medications were about 25% (vs. uptitration) and 50% (vs. switching) less likely to discontinue treatment. CONCLUSION: Treatment modifications are common among newly treated hypertensive patients, and the rates vary significantly across ADCs. In the real world, treatment modifications occur much later than the 30-day timeline recommended by guidelines. Addition of drugs may be a preferred approach for intensifying treatment of patients at a high risk of treatment discontinuation.
