(Anderson, et al., 2002)	To report the opinions of adult cystic fibrosis (CF) patients regarding the transition process.	Not discussed	Survey sent to 1,288 CF patients on a mailing list provided by the International Association of Cystic Fibrosis Adults (IACFA). 334 surveys returned = 25.9% response rate.	Des, Quant, Cross-section	CF Transition Survey: Patient Version. Questions addressed why patients do not receive care at CF centers, why they do not see internists, transition programs, concerns, transfer process, assuming responsibility for care, and the adult CF team’s ability to manage emotional and medical needs	Characteristics were compared using either chi-square statistics or Hotelling’s T2 test. Analysis of variance statistics to compare perceptions of patients’ concerns about transition as rated by CF program directors to concerns as rated by the patients.	24% patients seen at a CF center received care from a pediatrician, while 76% were followed by an internist or family practitioner. The groups did not differ significantly in age, gender, employment, or parental status. Patients seen by a pediatrician were more likely to be full-time students and to live at home with parents than those seen by an internist. 76% of the 67 patients followed by pediatricians reported no available adult program. Of age, marital status, and pregnancy, the most frequently cited criterion for transfer was age. The transfer concept was introduced to 10% of patients prior to age 15 years. Most CF patients felt the list of concerns in the survey were either “not a problem” or only a “mild problem” Physicians perceived greater patient concerns than patients reported themselves; the pediatricians perceived greater concerns than did the internists, Patients rated importance of a transition program prior to transfer to an adult program as “moderate”	Potential bias of population: motivated population that joined IACFA. 26% response rate: this group was perhaps more independent, more ready for transfer, older, past the age of recommended transfer.

Not discussed	25 transition-aged youth between 14 and 21 years with special health care needs who were seen in the Creating Healthy Futures transition clinic between February 1, 1999, and September 30, 2001	Des, Retro, Quant, Cross-section	Information obtained from charts included demographics, diagnoses, years since diagnoses, living arrangements, family structure, education, and employment. Self-care items were from the California Healthy and Ready to Work Transition Health Care Assessment tool. 72 questions assessed: knowledge and skills related to condition, preventative and emergency health care measures, health-related accommodations, community resources, long term disability management, communication, health insurance, responsible sexual activity, legal protections, and transportation.	Domain-specific summary percent measures for positive and negative responses were obtained for each subject. Summary percents of positive (“yes”) and negative responses were calculated. Student t-tests were used to contrast domain-specific skills between diagnostic groups.	More than 90% of respondents answered yes to: current with immunizations and health care screenings, recognize when they are getting ill related to their SHCN, have a primary care physician, brush and floss their teeth, and recognize when they are getting sick with a cold or urinary tract infection. More than 75% of the respondents answered no to: have a MediAlert bracelet/necklace, applied for other public services, understand the ADA rights, and use Access Van Domains with highest percent yes responses were monitor health condition, track health records, obtain information and reproductive counseling, and responsible sexual activity. Domains with the lowest percent yes responses were knowledge of legal rights and protections, understanding of need for environmental modifications/accommodations, manage SHCN, and knowledge of health insurance concerns/issues. Domains with highest percent no responses were knowledge of legal rights and protections, engage in preventative health behaviors, access community resources, knowledge of health condition/management, and use transportation safely. Domains with lowest percentage of no responses were track health records, responsible sexual activity, monitor health condition, understanding of need for environmental modifications/accommodations, and knowledge of emergency measures	All data were self- reported, which could have resulted in overestimation of self-care behaviors and socially desirable responses. Respondents may not have fully understood questions. Parents may have provided proxy responses. Findings cannot be generalized due to small sample and instrument limitations.

(Boyle, et al., 2001)	To identify expectations and concerns of patients and families transitioning into an adult CF clinic	Not discussed	before transition survey administered to: Pediatric Cystic Fibrosis Family Education Day attendees, patients at pediatric clinic scheduled to transition to adult care within 3 months. 52 patients and 38 parents completed questionnaires. Posttransition survey to patients previously cared for at pediatric clinic who transitioned to adult program	Exp, Pros, Quant, Cross-section	the 22-question survey was based on review of previous studies on CF transition, discussion with adult and pediatric team members, and 4 adult patients	Mean scores and standard deviations were calculated. Paired and unpaired t- tests were performed.	For the pretransition survey, concerns for patients prior to transition were: potential exposure to infection, leaving previous physician, meeting new care team, and potential decrease in quality of medical care. Prior to transition, important expectations included: phone access to a nurse, education about adult CF issues, confidence that adult CF team could provide quality care. 60 patients completed the posttransition survey. Of the 52 patients who completed the pretransition survey, 30 had previously met the adult team and 22 had not. Patients who had not previously met the adult team had higher levels of concern in all areas. Patient concern about leaving previous caregivers increased once they had been in the pediatric clinic for 3+ years. 8 of 38 parents expressed fear that transition to adult program would prevent them from being as involved in their child’s CF care.	Groups surveyed did not represent all undergoing transition. By surveying onlyparents who attended family day or who accompanied child to clinic visit, concerns of parents less active in their children’s care may have been excluded.

Des, Retro, Quant, Cross-section	13-question survey developed after discussion with primary care pediatricians, parents and patients. It addressed: policies and practices, timing, processes of adolescent transfer, barriers to transfer, role of health plans, practitioner experiences with transfer.	Descriptive frequencies were calculated. X2 test was used where applicable. SAS used for statistical analysis.	87% indicated that their practices had not yet developed written practice policies on the transition and transfer of adolescents with and without special needs. 70% reported having no difficulty in finding adult providers for adolescents. Age out is the most common reason to leave pediatric care. Drop out and moved out occurred more frequently for adolescents without special needs than for those with special needs. More adolescents with special health care needs hung out compared with peers without special needs.	Survey asked for a mix of factual responses, opinion, and estimations because quantitative data were not available from most practices. This limited statistical analysis.

Similar rates were seen for 22- to 25-year-olds.	Self-report may be subject to recall and nonresponse bias. Nonresponse and loss to follow-up may have made the study sample different from the population. Assessment for disability occurred at differing points during study follow- up; therefore, unknown how many young adults developed limitations after study onset or if limitations resolved during study.

Des, Retro, Qual	Semi-structured interviews began with the adolescent’s earliest memory of having diabetes and continued to the present.	Grounded theory	Gaining freedom was the central phenomenon that captured the process of gaining self-responsibility in diabetes management during adolescence. Three themes marked the process: a) making it fit; b) being ready and willing; and c) having a safety net of friends. These adolescents described a gradual transition from dependence to independence in learning to live with diabetes. One adolescent explained how he practiced making decisions and gaining independence from his parents and health care providers by creating a collaborative relationship with them.

Perceptions of the program directors were evaluated using Hotelling’s T2 test, comparing the results of pediatric program directors to those of adult program directors.	Of the pediatric programs that responded, 35% had a CFF-approved adult program, 22% had an internist on the team, and 39% has no specific adult program. 22% cited lack of an available adult CF physician as an impediment to establishing an adult CF program. Age (82%) was frequently a criterion for transfer, but marriage (17.1%) and pregnancy (24.8%) were not. Issues that hindered transfer included patient/family resistance (51.4%), medical severity (50.5%), and developmental delay (46.7%). Transfer to the adult program was introduced to patients and families at average age of 15.9 years 52% of respondents reported that patients did not meet the adult team until the time of transfer. Pediatric directors expressed perceived concerns about adult team capacity to meet medical and emotional needs of patients and families. Pediatric directors also viewed patients as having concerns about severing relationships with the pediatric staff and reluctance to leave pediatrics. Ratings of success of transition programs were inversely correlated with concerns about adult staff meeting patients’ medical and emotional needs.

Patient age was the most commonly cited criterion that led to patient transfer. 86.2% endorsed CF patients being transitioned by the time they reach age 21 years. Patient/family resistance to transfer (45%), disease severity (34%), and developmental delay (31%) were the most common factors that would prevent transfer. Team members rated perceived patient concerns about transfer as “mild” to “moderate.” A majority of respondents reported feeling that their transition program was moderately successful. This did not depend on team role. Team members and internists held similar concerns regarding transition. These are greater than concerns endorsed by patients themselves.	Not discussed	Meso

Variation by disability of child assessed with analysis of variance (ANOVA)	Activities identified as having the greatest importance to parents included: taking care of general health and disability, coordinating care, helping to get health insurance, finding an adult provider, teaching how to manage health, and working with the school to coordinate care. Areas with the greatest differences between parents and providers were: talking about drugs and alcohol; teaching how to manage health; and talking about sexual issues Barriers to transition reported by providers included: time, needing more training, financial reimbursement, needing more information from families before participating. Parents’ qualitative comments for improving transition: coordinated care, provider training in transition, a more holistic approach to health and well-being, working directly with adolescents.	Parents’ and providers’ responses could not be matched. There was not a one-to-one correspondence between the providers referenced by parents and providers who completed the survey.

Common issues were identified by consensus. A transitioning advisory committee with 13 members from practitioner, adolescent, and parent focus groups, the adult health care consumer group, and the State Department of Rehabilitation confirmed findings and developed a framework.	Adolescents’ concerns: leaving familiar, trusted people and place; going to an adult doctor who was unfamiliar with treating SCD; and worrying that parents would not let them grow up, leave home, or visit the doctor alone. Adolescent expectations: doctors would speak to them rather than through parents and that they would go to the clinic alone; physical setting would be less child-like; and they would receive current info on SCD research Adolescent preparation needs: provide education on how to manage SCD and new research; orient them to new doctors and clinic; meet adults with SCD who go to the same doctor. Parent concerns: losing their own support system and anticipating role change. Practitioners’ perceived barriers: overly dependent families and youth; pediatric providers who foster dependency; lack of communication between pediatric and adult providers; and lacking insurance coverage. Practitioners’ reported factors that indicate readiness: age, educational level, emotional maturity, independent functioning, being able to keep appointments Practitioners said a transition program should be at a comprehensive center with a support structure for the family and separate educational components for the practitioners. The purpose should be: teach self-responsibility; educate patients and parents on the disease complications and treatment; prepare the adult team; prepare the child team to transfer the adolescent.	Results cannot be generalized to a larger population due to small sample size and the fact that participants were not a random sample representative of the target population.

Parents agreed with “helping children interact in a variety of settings.” This required involving the community and tailoring activities for child’s abilities. Parents highly agreed with “Assigning appropriate household chores.” 2 items that received the lowest scores “find out about school-to- work programs” and “encourage teen to contact Vocational Rehabilitation” targeted work identity. Many parents had never heard about school-to-work programs. The item with the lowest level of agreement was “see your pediatric provider and adult provider for one year prior to transition.” While some said this was a “wasteful, costly, and controlling activity,” one parent thought this would “encourage transition rather than just a transfer…” Parents felt that health professionals versus parents played a larger part in “help your children talk to their health care providers to aid the child taking responsibility for their own health care.” Parents recommended health professionals talk directly to the child, listen, and encourage them to talk and learn about their diagnosis and how it affects them.

Descriptive statistics for transition processes were generated using frequency weighting to account for variable numbers of respondents across centers. Analysis of variance tests used to compare responses across respondent roles and program types.	Patient Preparation: Initial discussion of transition occurred at median age of 17 yrs. Transfer occurred at median age of 19 yrs. Half of programs allow patients to delay or decline transition. Reason: end-stage disease, developmental delay, patient/physician unwillingness, lung transplantation. 28% of programs consistently offer transition visits.<25% of programs “usually” or “always” provide transition education materials.<50% provide a transition timeline. Readiness Assessment: 50% CF programs assess readiness, and <10% have a written list of self-management skills. readiness assessments were infrequently reported for identifying and contacting insurer (26%) or understanding insurance benefits (43%). Primary Care: 62% of programs reported that patients “usually” or “always” had a primary care provider (PCP). CF teams were “usually” or “always” aware of the PCP and informed them about a transfer of CF care at 68% of programs. Coordination of Services: Anticipated changes in insurance coverage were “usually” or “always” discussed at 76% of programs Information Transfer: >80% of programs discussed transition of individual patients at pediatric team meetings; however, only one third of programs reported that adult care providers were present at meetings. 46% of programs reported “never” or “rarely” preparing a medical summary before transfer. Patient Follow-up: Almost 60% of programs that transfer care reported a mechanism to confirm first visit with adult clinic.

Future expectations of students and parents: Themes included a) future living expectations; b) future career and postsecondary education expectations; and c) the role that professionals and school programs play in supporting future expectations. Implementation of transition planning: a) school-based transition planning as is required by IDEA. b) whether participants had begun planning for the transfer of health care services from the pediatric to adult medical systems. Over half indicated no planning for transition of health care services had occurred because youth required continued services past 21 and the family expects Medicaid to continue to pay; mother anticipates the process of obtaining funding for health care coverage to be time-consuming and difficult; health care was provided by private insurance or settlement and will continue into adulthood; the mother provides all health care support and will continue to do so. Not planning led to youth’s concerns regarding changes in government policies related to medical services and funding.

All patients regarded parents, esp mothers, as key to record keeping. Patients recognized the importance of managing healthcare information but delegated to parents. Patients remembered some pertinent healthcare events but not to the same degree as mothers. Medical records maintained by families were organized chronologically. Patients and parents reported that standard questions on medical forms failed to capture the complexity of spina bifida care. Providers asked the same generic questions again and again. Patients and parents felt that many healthcare providers deliberately did not want them to have access to their medical record. They perceived that their medical information belonged to them and not to providers and institutions. Patients and parents also expressed concern that healthcare institutions did not share medical information. Parents and patients supported online access to medical records. Medical emergencies highlighted the need for a complete and accessible medical record.	Small sample and qualitative, exploratory, and descriptive nature limited findings. Participants represented motivated parents and well functioning patients. Specific needs of spina bifida patients seeing a large number of sub- specialties may have shaped responses.

First set of models examined factors associated with treatment comfort. Second set examined whether treatment comfort was associated with primary care physicians’ views on whether an adult- focused generalist provider was best suited to provide care for young adults with either CF or SCD	Internists and pediatricians were similarly comfortable in being the PCP for 17–25 year old patients with SCD, but less comfortable being the PCP for patients with CF and congenital heart disease. Both were more comfortable treating patients with common diseases than treating patients CF and SCD. About half of general pediatricians reported that a pediatrician (generalist or specialist) should be delegated primary care responsibility for an 18-year-old young adult with CF or SCD Over 80–90% of internists thought an adult-focused provider (generalist or specialist) should take responsibility for the primary care needs of an 18-year-old young adult with CF or SCD. 24% of internists and 21% of pediatricians report insufficient training severely or significantly limited ability to provide care to young adults aged 17–25 with chronic illness. Pediatricians were more likely than internists to report barriers due to insufficient time, insufficient mental healthcare support, insufficient social work support. Experience treating a larger number of patients with CF and SCD in practice was associated with higher treatment comfort for both internists and pediatricians Higher treatment comfort among internists was, in turn, significantly associated with delegating to an internist primary care responsibility for patients aged 18 with CF and SCD.	Study did not assess comfort level of other provider types. Results may have differed if study used an older age range in questions. Study did not assess comfort of internists in treating youth without chronic conditions, so lack of comfort cannot be attributed entirely to treating chronic conditions. Estimate of treatment comfort could be biased if there was systematic bias among non- respondents. Cross-section design did not show causality. Lack of association between ready access to subspecialists may be because most internists had subspecialty access. Focus on CF and SCD prevented generalizability to other diseases.

Most participants acknowledged the primary areas of stress were related to health insurance, finances and daily schedule, or the idea of needing to fit therapies and health care into a very busy time of life. 6 participants identified health coverage as a significant stress. Insurers refused to pay for equipment or medications. Having CF placed a significant stress on finances because of co-pays, deductibles, non-covered services, medications and nutritional requirements. Finances and insurance were not concerns until becoming an adult and assuming these responsibilities. All participants felt they were different from peers without CF in this aspect of transition. New Responsibilities. Most felt they had taken over responsibilities for health care such as scheduling clinic appointments, performing daily therapies and obtaining medications long before entering adulthood. None reported changing treatment regimens once they were on their own, but some described the need to take more initiative without a parent there reminding them to do therapies.	Findings were exploratory and Could not be generalized to all young people with CF due to the small sample size and nonrandom sample.

Content analysis methods were used in which the unit of analysis is a statement (or group of statements). A set of thematic categories was developed with a definition for each category; these were coded and three independent coders validated the codes. A grounded theory approach was used to develop themes and to organize the ideas that emerged. Data were analyzed by coding and constantly comparing codes. Segments of the text associated with a particular code or combination of codes were retrieved. Frequency tabulations for each category and code were computed across participants.	One overriding principle, that health care providers should feel comfortable caring for patients with disabilities, influenced all three themes. barriers to successful transition included: the difference between pediatric and adult health care, late introduction to transition, parents who had trouble letting go, becoming burned out on health care, not being included in choices or decisions, and not planning for transition. what helps transition: the pediatric provider had introduces the teen to an adult provider, provider explains the options of care with a rationale for each, choices, communication, and provider gender. strategies for successful transition: having the pediatric provider suggest an adult provider and give the adult provider the teen’s pertinent history, having a mentor, having a nurse oversee the transition process, for the teen to become an expert on his or her own health care condition, peer-written resources distributed via the internet, inservice for adult providers to help providers understand what it is like to have a disability, and viewing someone with a disability as a person	The qualitative study results cannot be generalized to all teens and young adults with disabilities.

A researcher coded transcripts and organized themes into 3 domains: stages of transition, health care systems, and transition narratives. Narrative analysis to understand the meanings of HCT and the beliefs held about the process was conducted on transition stories.	2 factors had a significant effect on the process and outcomes of HCT: cognitive ability of the young adult and the progressive nature of the SHCN or disability. Participants viewed transition as a developmental process with 3 stages: 1. envisioning a future: Envisioning the child growing up to be an adult helped promote future planning. Plans changed as child’s abilities emerged over time. 2. age of responsibility: family members taught and gave responsibility to the child to carry out tasks of daily living and medical self-care. Examples included talking with providers, ordering and taking medications, and developing positive habits and routines. 3. age of transition: divided into 2 periods of adolescence and young adulthood. Maturity and experience were necessary to carry out successfully medical responsibilities. Participants noted differences in pediatric and adult-oriented systems that created barriers to transition. Four systems barrier are: 1. aging out; 2. insurance/funding; 3. availability of care: it was difficult to find A-OPs who matched pediatric providers in knowledge about, training in, and experience with disability or SHCN; 4. practice differences: organization of care, communication between pediatric providers and A-OPs, and family involvement	Many disability/diagnoses were represented by the participants, but only a few individuals had experience with a given condition. Differences that exist in the transition experience of individuals who represent different conditions could not be identified or addressed.

No respondent reported becoming aware through institutional policy, clinical guidelines, or requests for referrals from adult providers. All endorsed as very important: 1) adolescents should be able to describe the signs and symptoms requiring urgent medical attention; and 2) adolescents understand the implications of their condition and treatments on their sexuality and reproductive health. Second-order priorities included: 1) importance of young adults addressing insurance access; 2) ensuring adolescents’ awareness of condition-specific supporting organizations; and 3) the ability of adolescents to describe the roles of primary care providers and subspecialists. Primary care providers believe individualized care for their patients rather than a uniform protocol is key to transition. Respondents acknowledged as significant transition barriers: difficulty identifying adult primary care providers; adolescent and family resistance; lack of institutional support	The sample was not representative of physicians in North America and did not allow for generalization to all physicians.

All subjects were patients of the specialty services of a large children’s hospital and had participated in a longitudinal study with 155 youth about healthcare preferences	Des, Qual	Each participant completed a questionnaire and open-ended interview regarding healthcare preferences at each of three planned visits over an 18-month interval. The open-ended interview script allowed interviewer to discuss transition if subject raised the issue. Interviewers indicated themes in a set of pre-coded boxes. One theme was transition. Subjects in this analysis discussed transition during interviews.	48 transcripts were analysed. Two investigators reviewed transcripts, reaching consensus about major transition themes. Longitudinal changes in opinions examined. An overall emergent coding scheme was developed based on these themes. Theoretical constructs were developed for content related to timing, parents’ changing role in health care and attitudes and concerns of subjects before and after transition to adult care.	Key themes as subjects progressed through the transition process: beliefs about the desirability of transition, feelings about current medical care, relationship with current providers and decision making/parents’ role in the process. Views about these themes varied over time. Parents played a significant role during transition. Many reported that their parents’ support and involvement were important to successful transition. Most felt empowered by making a break from parents and seeing provider alone, despite reported parental difficulty with this change. Most adolescents anticipating transition expressed negative aspects to transfer and felt unprepared to transfer. Perceived downsides of adult care included having to start over with a new provider, bringing a new team up to speed about medical history, concern that medical and psychosocial issues were too complicated for future adult provider, and concern about the unknown. Once transferred to an adult specialty provider, many were pleased with new providers. Many subjects appreciated the efficiency of the adult system but missed the nurturing setting of paediatrics. Others were concerned that the briefer interactions meant providers were less qualified. Some subjects believed it would have been helpful to start transition earlier. Others believed that being introduced to future adult specialists and being able to visit the adult venue would have helped.	This secondary analysis was unable to tailor interviews to address issues that arose during data analyses. Limited data are available for some areas.	Indiv: Subj exp Micro: Fam, prov Meso
(Wang, et al., 2008)	To address the questions: are youth with non-severe and severe disabilities more likely to experience insurance loss compared to youth without disabilities? Does the type of insurance that a youth possesses affect the likelihood of loss of coverage?	Not discussed	2,123 insured youth without disabilities, 320 insured youth with non-severe disabilities, and 295 insured youth with severe disabilities, ages 15–25 years. Nationally representative sample	Des, Quant, Cross-section	Survey of Income and Program Participation (SIPP) 2001	Descriptive statistics to characterize youth who maintained or who lost insurance. Significant differences between youth were assessed using chi-square tests. Logistic regression to calculate the association between disability status and loss of insurance	36% of insured youth without disabilities lost insurance over three years compared to 43% of insured youth with non-severe disabilities and 41% of insured youth with severe disabilities. Youth with non-severe and severe disability on public insurance had lower odds of losing insurance compared to youth without disabilities on public insurance. Youth with severe disabilities had higher odds of losing health insurance compared to youth without disabilities. Youth with non-severe disabilities and youth without disabilities on private insurance had similar odds of losing insurance.	Disability variable was an imperfect measure for non-severe and severe disability. Disability was treated as a static characteristic over 3 years even though impairments likely changed over time. Study did not consider whether individuals changed insurance types before losing insurance coverage. Cross-sectional study estimated association only and not causality.	Exo: Nat-state prog
(Wiener, et al., 2007)	To examine whether an association existed between transition readiness, specific barriers to transition, and level of state anxiety. An intervention by physician or social worker was conducted for each transition barrier. Hypothesis: readiness scores would increase and state anxiety scores would decrease between two time points as a result of the intervention.		65 children and adolescents with HIV at the National Institutes of Health. 51 families participated in the transition readiness program.	Exp, Quant, Long	Transition Readiness Scale: designed by the investigators to obtain information on factors identified in the literature as obstacles to successful transition State portion of the State/Trait Anxiety Inventory for Adults: measures a transitory emotional response to a stressful situation and consists of 20 phrases with responses on a 4-point Likert scale.	Paired sample t-tests to compare readiness and state anxiety scores between Time 1 (T1) and Time (T2). A change score was calculated for each respondent based on their readiness and state anxiety scores at T1 and T2. Independent samples t-tests were conducted to see whether any of the summary need variables at T1were related to the amount of change between T1 and T2 for both readiness and state anxiety.	Participants of the transition readiness program completed two sets of identical interviews, mean 6.8 months apart Between T1 and T2, mean transition readiness scores increased significantly and state anxiety decreased significantly At T1, readiness was negatively correlated with state anxiety and years at NIH. These relationships were no longer significant at T2. Between T1 and T2, the most notable improvements were in need for home physicians, social workers, and knowledge about disease status, names of prescribed medication, and dosages. There was no significant relationship between readiness and disease status (CD4, viral load) at either T1 or T2.	No follow-up data on whether the participants effectively utilized the medical care in their new clinical centers. Transition scale was designed for the study and reliability and validity data were needed. Results may be skewed towards those youth less ready for transitioning.	Indiv: Subj exp
(Wojciechowski, et al., 2002)	To address the research questions: 1) Do youth who transfer from pediatric care (PC) to adult care (AC) receive preparation before transfer? 2) Do youth who transfer to AC receive uninterrupted care? 3) Do youth who transfer to AC comply with the medical treatment regimen? 4) Do youth who transfer to AC move towards independence?	Not discussed	Convenience sample of 18 young adults with sickle cell disease, between the ages of 18 and 24 years old, who had transferred to adult care and their providers. All patients, with the exception of one, transferred to an adult center between March 1996 and April 1998.	Des, Quant, Cross-section	Historical data were obtained through record review and face-to-face contact or telephone interviews with primary providers. past and present experiences were obtained through face-to-face interviews with youth participants. Data were collected with: Demographic and Informational Inventory, Pediatric Site Review Form, Adult Site Review Form, SCD Compliance Questionnaire, Self-efficacy Scale for Managing SCD	Descriptive and frequency techniques. nonparametric statistical tests to examine correlations between variables	None of the participating sites had a formal process to transition patients. All participants except one transferred to the only adult care center in the city’s metropolitan area. 11 youth had no preparation before going to adult care. 7 had preparation that ranged from a one-time discussion to making a telephone call to the adult care center. 7 participants were transferred to adult care because of age. Regarding continuity of care, 11of 18 youth kept their first adult care appointment	Small sample size precludes determining if any relationships exist among variables or making generalizations to other populations. Potential cases were lost to follow-up, and this may have explained absence of differences between those who had preparation and those who did not. Those lost to follow-up might have been less compliant and less self-efficacious. Study was unable to compare to other adult care centers. Lack of information on ED visits and use of other providers in addition to primary provider made it difficult to track health status and care received.	Indiv: Person char Exo: Health services
(Zack, et al., 2003)	to investigate the perspectives of adolescents and adults with CF who receive care at a children’s hospital regarding preventive health counseling and transition issues.	Not discussed	37 consecutive patients 16 years old and over who were diagnosed with cystic fibrosis and received care at the CF Center at Children’s Hospital Boston were approached to participate. 32 youth completed the interviews.	Des, Quant and Qual, cross-section	57-item (19 structured interview questions, 8 open-ended questions, and 30 self-administered questions) survey instrument was reviewed by clinicians and by researchers. It was pilot-tested with 10 adolescents interviews lasted 30 minutes.	Quantitative data were analyzed across age, gender, and severity of illness using chi-square, t-tests, and Mann-Whitney U tests for non-normally distributed data. Qualitative responses from open-ended question included patients’ experience and thoughts. Responses were transcribed from notes taken during interviews. Three authors independently examined responses and grouped phrases into themes. The frequency of responses under each theme was tabulated.	Nearly 70% of patients identified a pulmonologist as their “main doctor,” even though three-quarters reported having a primary-care provider 97% participants reported spending time alone with their main doctor. Most considered 13 to 16 years to be the best age to start spending time alone with main doctors. 16 identified increased independence in making decisions about care and assumption of greater responsibility as changes that occurred as they’ve grown older. In response to questions about best features of receiving care at the pediatric hospital, 30 responses highlighted the importance of patient-provider relationship. 11 patients (30%), all inpatients, had considered transferring care; the other 70% had not considered transferring care based on medical, personal, or financial concerns. One patient had transferred care and returned to the pediatric hospital due to “harsh care in the adult world.”	Small sample size. Study included patients accessing medical care. Comparisons looking at patients who had transitioned were not feasible. Participants represented a sample from one CF center, and other centers may have had different experiences and care arrangements. Some results may have represented lack of experience with an alternative system and/or absence of transition programs.	Ind: Person char, Subj exp Micro: Prov
(Zebrack, et al., 2004)	To identify barriers/obstacles to obtaining appropriate follow-up care; To elicit suggestions for components and models of care having the greatest potential for success; To assess potential ways to enhance health care for the survivor population	Not discussed	21 expert panelists invited based on history of participating in cancer survivorship efforts or advocacy. 20 agreed to participate. 19 panelists were survivors of childhood malignancies, 1 was the mother of a deceased cancer patient. 17 participants completed all three survey rounds.	Des, Qual	Delphi method used to formulate a list of ideas and to develop group consensus concerning the relative importance of those ideas.	multidisciplinary team analyzed, and interpreted data from three rounds of questionnaires.	After the third round of survey, the top ranked barriers: Survivors lack knowledge about late effects and are unaware of risks; Lack of insurance; Lack of training/education of primary care physicians about health problems of survivors; (Tie) Lack of training/education of specialists regarding health problems of survivors; 4. (Tie) Limited number of adult health care providers equipped to deal with childhood cancer survivors. 5 top initiatives to enhance care: Education of health care professionals; Education of survivors; Provide written medical synopsis that summarizes chemotherapy, radiation, operative and pathology reports and current medical problems and medications; help survivors maintain or rebuild their medical history; More research in late physical and psychological effects; Develop and implement protocols for follow-up visits Components of optimum health care: Focus on educational activities; Focus on screening; Accessible medical record; Uncomplicated and convenient access to specialists; Ongoing communication between all providers; Inexpensive care; National web-based information center with resources.	The views expressed were primarily those of the panelists. Demographics of the panelists lacked racial/ethnic diversity. The panel did not include survivors who practice avoidance or wish to forget their cancer experience. Empiric findings reported in the study are not meant to be definitive conclusions with respect to the needs of young adult cancer survivors.	Exo: Health services
