RESUMO

CONTEXT: Throughout the COVID-19 pandemic, state and local health departments served as risk communicators to the public; however, public health practitioners have limited resources at their disposal when trying to communicate information, especially when guidance is rapidly changing. Identifying how the population gathers information across channels and which subsets of the population utilize which channels can help practitioners make the best use of these limited resources. OBJECTIVE: To identify how individuals utilized different information channels to get COVID-19-related information and determine its effect on one COVID-19-related action: vaccine intentions. DESIGN: This study applies latent class analysis to utilization of information channels to characterize information consumption patterns during the COVID-19 infodemic and then explores the relationship between these patterns and vaccine hesitancy. SETTING: The data were collected from the COVID-19 Vaccine Hesitancy Survey , which is a nationally representative sample of US adults 18 years and older recruited from Social Science Research Solutions (SSRS)'s Opinion Panel. PARTICIPANTS: The online survey was conducted between April 7 and April 11, 2021, after the COVID-19 vaccine was available to all adults and enrolled more than 3000 respondents (n = 3014). MAIN OUTCOME MEASURES: Respondents were asked about their frequency of information seeking related to the COVID-19 vaccine, sociodemographics, and vaccine perceptions. RESULTS: Based on fit statistics and prior research, we identified 6 latent classes that characterize information seeking: Nonseekers, Legacy, Legacy + Facebook/Instagram, Traditional Omnivore, Omnivore + Broad Social Media, and Twitter. Sociodemographics, political, economic, and COVID-19 exposure variables are associated with different patterns of seeking information about COVID-19. Membership in 3 of these classes was associated with higher rates of vaccine refusal and vaccine hesitancy. DISCUSSION: The study has implications for public health officials and policymakers who use media channels to share news and health information with the public. Information should be tailored to the sociodemographic profiles of those users who are likely consuming information across multiple different channels.

RESUMO

INTRODUCTION: To investigate the absolute and proportionate number of menthol versus regular cigarette packs displayed on the shelves inside tobacco retail outlets (TROs) across New York City (NYC). AIMS AND METHODS: Photographic surveillance methods were used to capture the presence and proportionate amount of all visible cigarette packs on the shelves inside N = 160 TROs. Statistical analyses examined the absolute and proportionate number of menthol packs in each TRO as a function of NYC borough, the local TRO environment, population smoking rates derived from the NYC Community Health Survey, and other demographic indicators from the American Community Survey. RESULTS: The total number of cigarette packs on the shelves of each TRO and the proportion of menthol packs varied significantly across TROs, averaging about one-quarter of all packs displayed (M = 0.274; SD = .15). Modeling results indicate that the proportion of menthol packs displayed was significantly greater in areas with elevated population smoking rates (odds ratio [OR] = 1.03, CI: 1.01-1.06) and density of TROs per 1000 residents (OR = 1.23; CI: 1.01-1.49), although these associations varied in complex ways with the proportion living under the federal poverty level and the proportion under age 18 years residing within each zip-code. CONCLUSIONS: Results of this study demonstrate the utility of photograph-based TRO audit methods for objective, reliable documentation of the presence and proportionate amount of menthol versus other cigarette pack types on TRO shelves and highlight the need to account for sources of variation between small areas when examining the TRO product landscape and evaluating the effectiveness of regulatory actions against menthol. IMPLICATIONS: This study describes use of a "hands-free" surveillance technique that offers valuable advantages over traditional retailer surveillance techniques. Comprehensive photographic surveillance data collection allows for more objective measurements of, in this case, the retail outlet's tobacco power wall, as multiple coders can review the same images and interrater reliability can be empirically tested. The results of this analysis highlight the need to account for local variation between small areas when examining TRO product landscapes and the effects of policy changes at the retailer level.

RESUMO

Vaccine uptake variation across demographic groups remains a public health barrier to overcome the coronavirus pandemic despite substantial evidence demonstrating the effectiveness of COVID-19 vaccines against severe illness and death. Generational cohorts differ in their experience with historical and public health events, which may contribute to variation in beliefs about COVID-19 vaccines. Nationally representative longitudinal data (December 20, 2020 to July 23, 2021) from the Understanding America Study (UAS) COVID-19 tracking survey (N = 7279) and multilevel logistic regression were used to investigate whether generational cohorts differ in COVID-19 vaccine beliefs. Regression models adjusted for wave, socioeconomic and demographic characteristics, political affiliation, and trusted source of information about COVID-19. Birth-year cutoffs define the generational cohorts: Silent (1945 and earlier), Boomer (1946-1964), Gen X (1965-1980), Millennial (1981-1996), and Gen Z (1997-2012). Compared to Boomers, Silents had a lower likelihood of believing that COVID-19 vaccines have many known harmful side effects (OR = 0.52, 95%CI = 0.35-0.74) and that they may lead to illness and death (OR = 0.53, 95%CI = 0.37-0.77). Compared to Boomers, Silents had a higher likelihood of believing that the vaccines provide important benefits to society (OR = 2.27, 95%CI = 1.34-3.86) and that they are useful and effective (OR = 1.97, 95%CI = 1.17-3.30). Results for Gen Z are similar to those reported for Silents. Beliefs about COVID-19 vaccines markedly differ across generations. This is consistent with the idea of generational imprinting-the idea that some beliefs may be resistant to change through adulthood. Policy strategies other than vaccine education may be needed to overcome this pandemic and future public health challenges.

RESUMO

One's personal physician, national and state or local public health officials, and the broader medical profession play important roles in encouraging vaccine uptake for COVID-19. However, the relationship between trust in these experts and vaccine hesitancy has been underexplored, particularly among racial/minority groups where historic medical mistrust may reduce uptake. Using an April 2021 online sample of US adults (n = 3041) that explored vaccine hesitancy, regression models estimate levels of trust in each of these types of experts and between trust in each of these experts and the odds of being COVID-19 vaccine takers vs refusers or hesitaters. Interaction terms assess how levels of trust in the medical profession by race/ethnicity are associated with vaccine hesitancy. Trust in each expert is positively associated with trust in other experts, except for trust in the medical profession. Only trust in one's own doctor was associated with trust in the medical profession, as measured by factor scores derived from a validated scale. Lower levels of trust in experts were significantly associated with being either a hesitater or a refuser compared to being a taker. Black respondents had higher odds of being either a hesitater or a refuser compared to white respondents but the interaction with trust was insignificant. For Hispanic respondents only, the odds of being a hesitater declined significantly when trust in the medical profession rose. Mistrust in the medical profession, one's doctor and national experts contributes to vaccine hesitancy. Mobilizing personal physicians to speak to their own patients may help.

RESUMO

Objectives. To assess state policy environments and the relationship between state gun-control, gun-rights, and preemptive firearm-related laws in the United States. Methods. In 2019 through 2020, we evaluated substantive firearm laws and preemptive firearm laws across 50 US states for 2009 through 2018. For each state, we compared substantive measures with preemptive measures on the same policy topic for 2018. Results. The presence of state firearm-related laws varied across states, but with the exception of "punitive preemption" the number of gun-control, gun-rights, and preemptive measures remained unchanged in most states from 2009 through 2018. As of 2018, a majority of states had preemptive measures on almost all gun-control policy topics without enacting substantive gun-control measures. Several states had a combination of gun-control and preemptive measures. Only a small number of states had gun-control measures with few to no preemptive measures. Conclusions. Even where state legislators were unable to pass statewide gun-rights measures, they succeeded in passing preemption, preserving state authority over a wide range of gun-control and gun-rights policy topics. The majority of states used preemption as a tool to support policy frameworks favoring gun rights.

RESUMO

Unaccompanied migrant children seeking asylum status in the United States are often forced to undergo dental radiographs, or x-rays, to verify that they are younger than 18 years.The application of third molar dental radiographs is methodologically flawed and should not be employed as a determinant of chronological age. Furthermore, the use of such tests without obtaining informed consent from either the youth or an objective advocate is unethical.Finally, the legal and health consequences of these inappropriately applied tests are severe and jeopardize the safety and security of these vulnerable minors.

RESUMO

Brazil was a low and middle-income country (LMIC) in the late-1980s when it implemented a robust national tobacco-control program (NTCP) amidst rapid gains in national incomes and gender equality. We assessed changes in smoking prevalence between 1989 and 2013 by education level and related these changes to trends in educational inequalities in smoking. Data were from four nationally representative cross-sectional surveys (1989, n = 25,298; 2003 n = 3845; 2008 n = 28,938; 2013 n = 47,440, ages 25-69 years). We estimated absolute (slope index of inequality, SII) and relative (relative index of inequality, RII) educational inequalities in smoking prevalence, separately for males and females. Additional analyses stratified by birth-cohort to assess generational differences. Smoking declined significantly between 1989 and 2013 in all education groups but declines among females were steeper in higher-educated groups. Consequently, both absolute and relative educational inequalities in female smoking widened threefold between 1989 and 2013 (RII: 1.31 to 3.60, SII: 5.3 to 15.0), but absolute inequalities in female smoking widened mainly until 2003 (SII: 15.8). Conversely, among males, declines were steeper in higher-educated groups only in relative terms. Thus, relative educational inequalities in male smoking widened between 1989 and 2013 (RII: 1.58 to 3.19) but mainly until 2008 (3.22), whereas absolute equalities in male smoking were unchanged over the 24-year period (1989: 21.1 vs. 2013: 23.2). Younger-cohorts (born ≥1965) had wider relative inequalities in smoking vs. older-cohorts at comparable ages, particularly in the youngest female-cohorts (born 1979-1988). Our results suggest that younger lower-SES groups, especially females, may be particularly vulnerable to differentially higher smoking uptake in LMICs that implement population tobacco-control efforts amidst rapid societal gains.

RESUMO

BACKGROUND: There are no independent studies measuring the availability of premium brand counterfeit cigarettes in New York City from licensed retailers. METHODS: We forensically analyzed the cigarette packaging of Marlboro Gold (n = 1021) purchased from licensed tobacco retailers in New York City, using ultraviolet irradiation and light microscopy to determine whether they were counterfeit. RESULTS: We find that while only 0.5% (n = 5) of our sample exhibits at least one characteristic synonymous with counterfeit packaging, none of our packs can be conclusively classified as counterfeit. CONCLUSIONS: We do not find any counterfeit Marlboro Gold packs purchased at full price from licensed cigarette retailers throughout New York City. Future research using test purchases should include other venues (eg, street and online) and specifically ask for discounts to ascertain the overall presence of counterfeit cigarettes. IMPLICATIONS: This is the first study to independently measure the availability of counterfeit cigarette packs purchased at full price from licensed retailers in New York City. We find that none of the Marlboro Gold packs purchased from licensed cigarette retailers are counterfeit.

RESUMO

OBJECTIVES: To assess the impact of New York City's (NYC's) 2014 increase of the minimum legal purchase age (MLPA) for tobacco and e-cigarettes from 18 to 21 years. METHODS: We performed a difference-in-differences analysis comparing NYC to the rest of New York State by using repeated cross-sections of the New York Youth Tobacco Survey (2008-2016) and to 4 Florida cities by using the Youth Risk Behavior Surveys (2007-2015). RESULTS: Adolescent tobacco use declined slightly in NYC after the policy change. However, this rate of change was even larger in control locations. In NYC, e-cigarette use increased and reported purchases of loose cigarettes remained unchanged, suggesting uneven policy implementation, enforcement, or compliance. CONCLUSIONS: Increasing the MLPA to 21 years in NYC did not accelerate reductions in youth tobacco use any more rapidly than declines observed in comparison sites. Public Health Implications. Other cities and states currently raising their MLPA for tobacco may need to pay close attention to policy enforcement and conduct enhanced monitoring of retailer compliance to achieve the full benefits of the policy.

RESUMO

BACKGROUND: Brazil has made progress towards a more equitable distribution of health care, but gains may be threatened by economic instability resulting from the 2008 global financial crisis. This study measured predictors of health care utilization and changes in horizontal inequity between 2008 and 2013. METHOD: Data were from two nationally representative surveys that measured a variety of sociodemographic, health behaviors and health care indicators. We used Poisson regression models to estimate adjusted prevalence ratios and the Horizontal Equity Index (HEI) standardized by health needs to measure inequity in the utilization of doctor and dentist visits, hospitalizations and reporting of a usual source of care (USC) for those 18 and older. To estimate the HEI, we ranked the population from the poorest to the richest using a wealth index. We also decomposed the HEI into its different components and assessed changes from 2008 to 2013. RESULTS: The population proportion with doctor and dentist visits in the past year and a USC increased between 2008 and 2013, while hospitalizations declined. In 2013, pro-rich inequity in doctor visits increased significantly while the distribution of hospitalizations shifted from pro-rich in 2008 to neutral in 2013. Dentist visits were highly pro-rich and USC was slightly pro-rich; the distribution of dentist visits and USC did not change over time. Health need was a strong predictor of health care utilization regardless of the type of coverage (public or private). Education, wealth, and private health plans were associated with the pro-rich orientation of doctor and dentist visits. Private health plans contributed to the pro-rich orientation of all outcomes, while the Family Health Strategy contributed to the pro-poor orientation of all outcomes. CONCLUSION: The results of this study support the claim that Brazil's population continued to see absolute gains in access to care despite recent economic crises. However, gains in equity have slowed and may even decline if investments are not maintained as the country enters deeper financial and political crises.

RESUMO

BACKGROUND: New York City (NYC) raised the minimum purchase age for cigarettes from 18 to 21 on 1 August 2014. The new law is intended to decrease current smoking rates and smoking initiation among the city's youth. Assessment of compliance with existing cigarette sales and tax laws could aid in determining what may be needed for successful implementation of the city's new law. PURPOSE: To assess compliance with minimum sales price and purchase age laws in NYC, before change in law. METHODS: Ten trained field investigators purchased cigarettes from different types of retailers throughout all five NYC boroughs, resulting in 421 purchases. Investigators noted whether they were asked for identification and the price of their purchase. Multivariable logistic and Ordinary Least Squares regression techniques were used to assess predictors of retailer compliance with sales price and minimum purchase age laws. RESULTS: In 29% of purchases, investigators did not have to produce identification (p<0.05) to purchase cigarettes. Only 3.1% of sales were at prices lower than the minimum sales price. City borough was significantly associated with purchase without identification (p<0.001) and mean sales price (p<0.024). Vendor type (independent vs chain) was significantly related to investigators being able to purchase cigarettes without identification (p<0.001). CONCLUSIONS: Variation in compliance with existing laws suggests that more active monitoring of compliance with the new minimum legal purchase age will be required in order to realise the new law's public health potential.

RESUMO

BACKGROUND: New York City (NYC) has strict minimum cigarette price and tax stamp laws, but evidence regarding the extent of evasion of such laws in over-the-counter sales is scarce. METHODS: 830 packs were purchased at licensed tobacco retailers at 92 randomly selected neighbourhoods in NYC in spring and fall 2014, following the establishment of NYC's minimum price law. The χ(2) analyses of illegal tax stamps on pack, by retailer type and data collection period, are presented. RESULTS: Over 15% of packs purchased had out-of-state (4.5%) or counterfeit tax stamps (10.6%). Purchases resulted in at least one illegal pack obtained in 70% of neighbourhoods, largely from independent stores. In 21.5% of sampled neighbourhoods, it was possible to purchase an illegal pack each collection period. CONCLUSIONS: Enhanced enforcement of retail sales of cigarettes is needed to ensure the full benefit of existing tobacco control laws in NYC.

RESUMO

OBJECTIVES: New York City (NYC) is the first large city to increase the legal minimum age for possessing tobacco products from 18 to 21 (Tobacco 21) and establish a minimum price law to reduce smoking rates among youth. However, retailer compliance with these regulations is unknown. METHODS: Youthful investigators purchased cigarettes pre and post-Tobacco 21 implementation in 92 NYC neighbourhoods. Investigators recorded whether their ID was checked, the pack's purchase price, and observed compliance with additional regulations. Multivariable OLS and Poisson regression models assess pre and post Tobacco 21 compliance with ID checks and purchase prices, controlling for retailer type, location and compliance with other laws. RESULTS: Retailer compliance with ID checks declined from 71% to 62% (p<0.004) between periods, and holding constant other factors, compliance with ID checks and sales at legal prices declined significantly after the laws changed. Compared to chain stores, independent retailers had significantly lower compliance rates (p<0.01). CONCLUSIONS: Several aspects of tobacco control appear to have deteriorated in NYC. Greater attention to monitoring retailer compliance with all tobacco regulations will be important for Tobacco 21 laws to be effective in reducing youth access to tobacco products.

RESUMO

BACKGROUND: There are significant differences in the meaning and use of the term 'Reverse Innovation' between industry circles, where the term originated, and health policy circles where the term has gained traction. It is often conflated with other popularized terms such as Frugal Innovation, Co-development and Trickle-up Innovation. Compared to its use in the industrial sector, this conceptualization of Reverse Innovation describes a more complex, fragmented process, and one with no particular institution in charge. It follows that the way in which the term 'Reverse Innovation', specifically, is understood and used in the healthcare space is worthy of examination. METHODS: Between September and December 2014, we conducted eleven in-depth face-to-face or telephone interviews with key informants from innovation, health and social policy circles, experts in international comparative policy research and leaders in the Reverse Innovation space in the United States. Interviews were open-ended with guiding probes into the barriers and enablers to Reverse Innovation in the US context, specifically also informants' experience and understanding of the term Reverse Innovation. Interviews were recorded, transcribed and analyzed thematically using the process of constant comparison. RESULTS: We describe three main themes derived from the interviews. First, 'Reverse Innovation,' the term, has marketing currency to convince policy-makers that may be wary of learning from or adopting innovations from unexpected sources, in this case Low-Income Countries. Second, the term can have the opposite effect - by connoting frugality, or innovation arising from necessity as opposed to good leadership, the proposed innovation may be associated with poor quality, undermining potential translation into other contexts. Finally, the term 'Reverse Innovation' is a paradox - it breaks down preconceptions of the directionality of knowledge and learning, whilst simultaneously reinforcing it. CONCLUSIONS: We conclude that this term means different things to different people and should be used strategically, and with some caution, depending on the audience.

RESUMO

A universal question in network science entails learning about the topology of interaction from collective dynamics. Here, we address this question by examining diffusion of laws across US states. We propose two complementary techniques to unravel determinants of this diffusion process: information-theoretic union transfer entropy and event synchronization. In order to systematically investigate their performance on law activity data, we establish a new stochastic model to generate synthetic law activity data based on plausible networks of interactions. Through extensive parametric studies, we demonstrate the ability of these methods to reconstruct networks, varying in size, link density, and degree heterogeneity. Our results suggest that union transfer entropy should be preferred for slowly varying processes, which may be associated with policies attending to specific local problems that occur only rarely or with policies facing high levels of opposition. In contrast, event synchronization is effective for faster enactment rates, which may be related to policies involving Federal mandates or incentives. This study puts forward a data-driven toolbox to explain the determinants of legal activity applicable to political science, across dynamical systems, information theory, and complex networks.

RESUMO

Detecting and explaining the relationships among interacting components has long been a focal point of dynamical systems research. In this paper, we extend these types of data-driven analyses to the realm of public policy, whereby individual legislative entities interact to produce changes in their legal and political environments. We focus on the U.S. public health policy landscape, whose complexity determines our capacity as a society to effectively tackle pressing health issues. It has long been thought that some U.S. states innovate and enact new policies, while others mimic successful or competing states. However, the extent to which states learn from others, and the state characteristics that lead two states to influence one another, are not fully understood. Here, we propose a model-free, information-theoretical method to measure the existence and direction of influence of one state's policy or legal activity on others. Specifically, we tailor a popular notion of causality to handle the slow time-scale of policy adoption dynamics and unravel relationships among states from their recent law enactment histories. The method is validated using surrogate data generated from a new stochastic model of policy activity. Through the analysis of real data in alcohol, driving safety, and impaired driving policy, we provide evidence for the role of geography, political ideology, risk factors, and demographic and economic indicators on a state's tendency to learn from others when shaping its approach to public health regulation. Our method offers a new model-free approach to uncover interactions and establish cause-and-effect in slowly-evolving complex dynamical systems.

RESUMO

OBJECTIVES: We examined internal and external determinants of state's adoption of impaired driving laws. METHODS: Data included 7 state-level, evidence-based public health laws collected from 1980 to 2010. We used event history analyses to identify predictors of first-time law adoption and subsequent adoption between state pairs. The independent variables were internal state factors, including the political environment, legislative professionalism, government capacity, state resources, legislative history, and policy-specific risk factors. The external factors were neighboring states' history of law adoption and changes in federal law. RESULTS: We found a strong secular trend toward an increased number of laws over time. The proportion of younger drivers and the presence of a neighboring state with similar laws were the strongest predictors of first-time law adoption. The predictors of subsequent law adoption included neighbor state adoption and previous legislative action. Alcohol laws were negatively associated with first-time adoption of impaired driving laws, suggesting substitution effects among policy choices. CONCLUSIONS: Organizations seeking to stimulate state policy changes may need to craft strategies that engage external actors, such as neighboring states, in addition to mobilizing within-state constituencies.

RESUMO

BACKGROUND: Country-of-origin of a product can negatively influence its rating, particularly if the product is from a low-income country. It follows that how non-traditional sources of innovation, such as low-income countries, are perceived is likely to be an important part of a diffusion process, particularly given the strong social and cognitive boundaries associated with the healthcare professions. METHODS: Between September and December 2014, we conducted eleven in-depth face-to-face or telephone interviews with key informants from innovation, health and social policy circles, experts in international comparative policy research and leaders in Reverse Innovation in the United States. Interviews were open-ended with guiding probes into the barriers and enablers to Reverse Innovation in the US context, specifically also to understand whether, in their experience translating or attempting to translate innovations from low-income contexts into the US, the source of the innovation matters in the adopter context. Interviews were recorded, transcribed and analyzed thematically using the process of constant comparison. RESULTS: Our findings show that innovations from low-income countries tend to be discounted early on because of prior assumptions about the potential for these contexts to offer solutions to healthcare problems in the US. Judgments are made about the similarity of low-income contexts with the US, even though this is based oftentimes on flimsy perceptions only. Mixing levels of analysis, local and national, leads to country-level stereotyping and missed opportunities to learn from low-income countries. CONCLUSIONS: Our research highlights that prior expectations, invoked by the Low-income country cue, are interfering with a transparent and objective learning process. There may be merit in adopting some techniques from the cognitive psychology and marketing literatures to understand better the relative importance of source in healthcare research and innovation diffusion. Counter-stereotyping techniques and decision-making tools may be useful to help decision-makers evaluate the generalizability of research findings objectively and transparently. We suggest that those interested in Reverse Innovation should reflect carefully on the value of disclosing the source of the innovation that is being proposed, if doing so is likely to invoke negative stereotypes.

RESUMO

Playgrounds are assumed to be an important resource for physical activity. This study investigates seasonal utilization, user preferences, and perceptions of safety and upkeep of public playgrounds in New York City. A cross-sectional survey was conducted from May 2010 to January 2011 across 10 playgrounds in low/middle income neighborhoods in each of the five boroughs in New York City. A total of 1,396 adults accompanying children were surveyed. Outcomes included playground as main place of outdoor play, and perceptions of playground upkeep and safety. Covariates included socio-demographics and other characteristics of playground users. Multivariable logistic regression with playground/season fixed effects were used. Utilization varied substantially across the four seasons. Blacks had higher odds of reporting the playground as the main place of outdoor play (AOR 1.78, 95 % CI 1.13-2.80, p < .05). High income users had lower odds of reporting the playground as the main place of outdoor play ($60-$80,000: AOR 0.47, 95 % CI 0.29-0.76, p < .01, $80,000+: AOR 0.47, 95 % CI 0.28-0.79, p < .01). Racial differences in perceived upkeep and safety were not significant once playground/season fixed effects were included, highlighting the importance of neighborhood conditions. Women were more likely to report feeling unsafe within playgrounds (AOR 1.51, 95 % CI 1.12-2.02, p < .01). While some playground utilization is driven by individual characteristics, perceptions of public resources influences utilization and cannot be separated from neighborhood conditions. Increasing access to opportunities for physical activity for children requires new strategies beyond playground improvements.

RESUMO

Annual Wellness Visits (AWV) promote preventive care for older adults, yet uptake remains low. To increase AWVs, a Medicare Advantage (MA) plan in Puerto Rico contracted a medical group to provide home-based AWVs during the last quarter of 2020. Using data from 464 visits, we conducted descriptive and multivariable analysis to profile patient characteristics and identify predictors of mental health referrals. We found that 87% of patients had multiple chronic conditions, 75% were taking more than 5 medications, and the odds of a mental health referral were higher for those who also had a nutrition-related condition (AOR = 5.05, CI95: 1.76-11.88), diabetes (AOR = 3.34, CI95: 1.18-7.58), or an additional reported uncontrolled health issue (AOR = 28.18, CI95: 8.96-70.59). This strategy helped one MA plan reach high-need patients, but coordination of follow-up care is needed to ensure patients receive recommended services.
